Description

The present invention relates to a cord storage device that stores electrical cords and communication cords used in electrical appliances and communication devices (hereinafter simply referred to as appliances), hollow tubes or hoses through which liquids, gases, powders, etc. can pass, or solid ropes or cords, etc. (hereinafter collectively referred to as cords).

In a typical household, when a power socket or the like is located near the installation location of an appliance, the excess part of a cord that is not very long is simply wrapped or folded and placed near the appliance. The same method is used to dispose of not-so-long tubes, hoses, ropes, cords, etc. used in various industrial and medical fields, and similar problems arise. Proposals to simply wind a cord in a spiral shape and store it in a fixed case are already known in documents disclosed in patent publications. The device disclosed in JP 2000-49472 A has a hollow annular ring, a reel that the user can rotate above it, and a top cover above a disk-shaped bottom cover with an upward-facing recess, and the reel has a wire locking port for the cord. The folded part of the cord is inserted through the wire inlet port of the bottom cover to vertically lock the folded part of the cord into the wire locking port of the reel, and the cord is pulled into the space above and below the reel and wound up. The device disclosed in U.S. Patent No. 9,385,519 B2 is a device that uses the force of a spiral spring to pull a cord divided into two sections, upper and lower, into a fixed, enclosed case and store it in a spiral shape in the same direction. All of these devices store the cord in a fixed, large case, regardless of the length of the cord to be stored.

7. Another object of the present invention is to provide a cord storage device in which the cords are less likely to be deformed or damaged by the wrapping portion.
8. Another object of the present invention is to provide a cord storage device suitable for storing tubes and hoses.

In order to achieve the above object, the cord storage device according to claim 1 of the present invention comprises a substrate having a flat upper plate surface and a constant thickness with a constant front-to-rear width and left-to-right length, a one-side cord holding part provided on one side of the upper plate surface, a second-side cord holding part provided on the other side of the upper plate surface, a spiral cord holding means provided between the one-side cord holding part and the other-side cord holding part, and a cord winding means provided between the one-side cord holding part and the other-side cord holding part, and is characterized in that one-side bending loop part and other-side bending loop part are formed between the one-side cord holding part and the other-side cord holding part, and a spiral cord is formed around the one-side bending loop part and the other-side bending loop part to store the cord. With the above configuration, one-side bending loop part and other-side bending loop part are formed on the upper plate surface between the one-side cord holding part and the other-side cord holding part, and a spiral cord is formed around the one-side bending loop part and the other-side bending loop part, so that the cords can be stored thinly and compactly.

Here, the "desired height exceeding the height of the cord" is a height selected depending on whether the cord to be stored is wound in one stage or multiple stages. If you choose to wind only in one layer, you can set the height of the bending wheel shaft to the height of the cord to be stored, and the thickness of the cord storage device can be made thinner accordingly. With the above configuration, the cord can be wound more smoothly by rotating the winding part of the winding body to wind it in. In addition, the two bending wheels of the winding body firmly hold the spiral cord between the holding parts on one side and the other side, and can serve as a spiral cord holding means.

The device is characterized by having one bending axle and the other bending axle arranged side by side in the diameter direction of the side plates, a cord opening opened at a position above the cord gap of the upper side plate in a direction perpendicular to the straight line connecting the centers of the two bending axles with a width exceeding the thickness of the cord, and a cord winding means for a winding body having a rotating part provided on at least one side of the upper and lower side plates and rotatably held in the holding hole, and forming one bending ring part around one bending axle between the base part and the upper cover part between the one side cord holding part and the other side cord holding part, and forming the other bending ring part around the other bending axle to form one or more stages of spiral cord around the one bending ring part and the other bending ring part to store cords. With the above configuration, the upper cover part covers a wide range of the upper and lower surfaces of the spiral cord between the upper plate surface, preventing the spiral from collapsing or floating up and down even with rough handling, and obtaining a thin and flat cord storage device that can maintain the spiral state.

The cord storage device according to claim 5 is the cord storage device according to claim 4, which comprises a disk-shaped lower side plate that rotatably fits into the retaining hole on the base plate side of the base plate and has an outer diameter that exceeds the front-to-rear width of the base plate, a disk-shaped upper side plate that rotatably fits into the retaining hole on the upper cover side concentric with the lower side plate at a desired height interval above the lower side plate that exceeds the height of the cord, one bending wheel shaft and the other bending wheel shaft that are arranged side by side in the diameter direction of the both side plates, forming a cord gap at the center position between the upper and lower side plates, and a center of both bending wheel shafts at a position above the cord gap of the upper side plate.

With the above configuration, the main part of the spiral cord on the inside of the winding rotates together with the upper side plate and the lower side plate of the winding body, thereby reducing the winding resistance of the winding body and reducing wear and damage due to sliding friction of the cord with the upper plate surface and the lower surface of the upper cover part. In addition, the upper cover portion covers a wide area of the upper and lower surfaces of the spirally wound cord between the upper cover portion and the upper plate surface, preventing the cord from collapsing or floating up or down, and providing a thin, flat cord storage device that can maintain the spiral state.

The cord storage device of claim 6 is characterized in that, in the cord storage device of claim 2, it has a lower side plate that fits rotatably into the retaining hole, an upper side plate that is formed concentrically with the lower side plate at a distance of a desired height above the lower side plate that exceeds the height of the cord, one bending wheel shaft and the other bending wheel shaft that are arranged side by side in the diameter direction of the upper and lower side plates, forming a cord gap in the center between the upper and lower side plates, a cord opening opened at a position above the cord gap of the upper side plate with a width that exceeds the thickness in a direction perpendicular to the straight line connecting the centers of the two bending wheel shafts, and a turning portion provided on at least one side of the upper and lower side plates, and a cord winding means for a winding body that is rotatably held within the retaining hole, and one bending ring portion is formed around one bending wheel shaft between the one side cord holding portion and the other side cord holding portion, and the other bending ring portion is formed around the other bending wheel shaft to form and store a spiral cord arranged in one or more rows around the one bending ring portion and the other bending ring portion.

Hereinafter, an embodiment of the present invention will be described based on an example.
In the examples of the cord storage device shown below, the name of the article described as a cord is a general term for solid cords that can be wound up, as well as hollow tubes and hoses. The name can be replaced with the names of these articles as appropriate.

Figures 1 to 3 show a first embodiment of a cord storage device. Here, an embodiment of a cord storage device for a power cord is shown. The cord storage device 1a has a flat upper plate surface 2a, a base plate 3a with a certain thickness having a certain front-to-back width and left-to-right length, a one-side cord holding part 4a provided on one side of the upper plate surface 2a, a second-side cord holding part 5a provided on the other side of the upper plate surface 2a, a holding means for a spiral cord 15a, a front-side regulating wall 50a provided on the front side between the one-side cord holding part 4a and the other-side cord holding part 5a and a rear-side regulating wall 51a provided on the rear side, and a cord winding means 25a provided between the one-side cord holding part 4a and the other-side cord holding part 5a. A one-side bent loop part 13a and a second-side bent loop part 14a are formed between the one-side cord holding part 4a and the other-side cord holding part 5a, and a spiral cord 15a is formed around the one-side bent loop part 13a and the other-side bent loop part 14a to store the cord. The cord winding means used here is the inner cord manual winding means 25a.

The power cord of this embodiment is a cord 6a with an oval cross section. It is difficult to bend the vertical direction of the oval cross section horizontally. Since the cord 6a is to be bent, it is placed on the upper plate surface 2a so that the oval cross section is longer vertically, and is bent in the usual manner. The thickness of the cord related to the height here is the vertical length when the oval cross section is placed vertically. This is the same in the following embodiments.
Here, the other side cord holding portion 5a is located approximately to the right of the one side cord holding portion 4a, but not exactly to the right.

Both the cord holders 4a and 5a on one side and the other side are cord holders that hold both sides of the wound cord portion between them in position. In Figs. 1 to 3, the upper part of the cord holder 4a on one side is an open groove 7a, the outer upper part of the groove wall 71a on the rear side of the spiral of the spiral cord is inclined toward the rear of the spiral, the inner upper part of the groove wall has a protrusion 73a on the tip side of the spiral, the inner upper part of the groove wall 72a on the tip side of the spiral is inclined toward the tip of the spiral, the outer upper part of the groove wall 72a has a protrusion 74a on the rear side of the spiral, and a space is maintained between the groove wall 72a on the tip side of the spiral and the groove wall 71a on the rear side of the spiral so that the cord can pass through. The other cord holder 5a is also in the same manner with respect to the spiral winding, and a space is maintained between the front groove wall and the rear groove wall so that the cord 6a can pass through at any position. Here, when the inside of the spiral is wound clockwise, the outside of the spiral winds counterclockwise and becomes the tip of the spiral. The same applies to the following examples.

In Figures 1 and 2, this cord storage device 1a has a substantially straight cord 6a' with one side portion 6aa' of the cord 6a' fitted into groove 7a of one side cord holder 4a, and the other side portion 6ab' of the cord 6a' fitted into groove 8a of the other side cord holder 5a, and is attached to the upper plate surface 2a of the base plate 3a. Therefore, to remove one side portion 6aa' of the cord 6a' from groove 7a of one side cord holder 4a, as shown by arrow 9a, one side portion 6aa' of the cord 6a' is pushed forward and lifted while being tilted backward to the right side, so that one side portion 6aa' of the cord 6a' can be removed from groove 7a. To fit one side portion 6aa' of the cord 6a' into groove 7a of one side cord holder 4a, the opposite operation is performed.

On the other hand, the other cord retaining portion 5a also has an open groove portion 8a at its top, and the upper part of the right side (outer side) of the rear groove wall is inclined toward the rear (front side), while the upper part of the left side (inner side) of the front groove wall of groove portion 8a is inclined toward the front.
Therefore, the other side portion 6ab' of the cord 6a' can be removed from the groove 8a of the other side cord holder 5a by bending the other side portion 6ab' of the cord 6a' backward (toward the user) and lifting it while tilting it forward to the left as shown by arrow 10a. The other side portion 6ab' of the cord 6a' can be fitted into the groove 8a of the other side cord holder 5a by performing the reverse operation. There is a gap between the cord 6a and each groove, allowing the cord 6a to slide left and right with frictional resistance.

As shown in Fig. 1, the cord 6a' attached to the cord holders 4a and 5a on both sides is wound directly with the fingers of the hand. For example, as shown in the figure, the first finger of the hand is placed at the position indicated by the arrow 11a on the cord 6a', the second finger is placed at the position indicated by the arrow 12a on the cord 6a', and the fingers are pressed in the directions indicated by the arrows to rotate the cord in a rightward (clockwise) direction around the space between the two fingers, forming one bent loop portion 13a and the other bent loop portion 14a while continuing to wind the cord, thereby forming a spiral cord 15a. Here, this winding method is referred to as the cord inner hand winding means 25a.
The shape of the bent loop portion is the same, and it is optional to decide which side is the one bent loop portion and which side is the other bent loop portion. The same applies to the embodiments described below. The cord may be wound in either a left-handed (counterclockwise) or right-handed direction. This applies to all the embodiments described below.

The cord 6a' is folded in two at one bending loop 13a and overlapped at the other bending loop 14a, forming a spiral shape with one side and the other side of the folded portion of one bending loop 13a overlapping alternately, and is wound up. During the winding operation, one side portion 6aa of the cord slides inward (towards the other side) in the groove 7a of one side cord holding part 4a, and the other side portion 6ab of the cord slides inward (towards one side) in the groove 8a of the other side cord holding part 5a, and is wound up and stored in the cord storage device 1a. The part from the spiral cord 15a to the holding part is firmly pressed against the groove wall of the cord holding part by the repulsive force of the cord generated at the bent part, and does not come off from either side of the cord holding part. In addition, the wound shape can be maintained without slipping out due to frictional resistance with the groove wall side.

Figure 3 shows the state of the spiral cord 15a in which the cord 6a is fully wound inside the cord storage device 1a. Cords such as those shown in this embodiment are generally covered with rubber or soft vinyl or other rubber-like material, and have a certain resistance to external forces, i.e., rigidity, plasticity to deform due to a certain external force, and elasticity to repel a certain external force. The covering surface also has a certain resistance to rubbing with the contacting surface, i.e., friction resistance. The cord 6a stored in the horizontally placed cord storage device 1a in the shape of a spiral cord 15a as shown in the figure is usually held on the upper plate surface 2a by both cord holding means 4a and 5a without collapsing due to these properties of the cord itself. The above properties of cords are common to all the embodiments shown below.

In this embodiment, a spiral cord holding means is provided to hold the spiral cord 15a in position between the one-side cord holding part 4a and the other-side cord holding part 5a. It is made up of a front restricting wall 50a, which is provided at a fixed distance on the front side between the one-side cord holding part 4a and the other-side cord holding part 5a and extends to one and the other sides at a height exceeding the height of the cord, and a rear restricting wall 51b, which is provided at a fixed distance on the rear side and extends to one and the other sides at a height exceeding the height of the cord. The front restricting wall 50a and rear restricting wall 51b act to firmly hold the stored spiral cord 15a from the front and rear against movement, tilt, and vibration of the cord storage device 1a.

When the number of turns of the spiral cord 15a is small, the cord can be pulled out by pulling one side portion 6aa of the cord 6a and the other side portion 6ab of the cord 6a. When the number of turns of the spiral cord 15a is large, the cord can be pulled out by temporarily removing one side portion 6aa of the cord 6a and the other side portion 6ab of the cord 6a from the grooves 7a and 8a of the respective cord holding portions and then rewinding the cord. It is possible to provide a cord storage device that is convenient for organizing excess cords and the like that can be stored in an orderly manner on the flat upper plate surface 2a.

Figures 4 to 12 show a second embodiment of a cord storage device. In the following description of the embodiment, parts that are the same as those in the previously shown embodiment or parts that have the same functions are indicated by the same numbers with suffixes such as a, b, c, and d, and descriptions of these parts are omitted as much as possible, with the main differences being described.

Here, an embodiment of a cord storage device for a power cord is also shown. The cord storage device 1b has a base plate 3b with a flat upper plate surface 2b and a constant thickness with a constant front-to-rear width and left-to-right length, a one-side cord holding part 4b provided on one side of the upper plate surface 2b of the base plate 3b, a second-side cord holding part 5b provided on the other side of the upper plate surface 2b, and a holding hole 18b of a winding body opened in the vertical direction at a position on the upper plate surface 2b between the one-side cord holding part 4b and the other-side cord holding part 5b. The cord winding means is a winding body 25b consisting of a lower side plate 19b that can be freely rotated and a bending axle 20b and a bending axle 21b of a desired height exceeding the height of the cord that are arranged side by side on the lower side plate 19b with a cord gap 23b at a distance exceeding the thickness of the cord, and a turning part 22b provided at at least one place around both bending axles including the lower side plate 19b.

As shown in Figures 4 to 6, the cord 6b is inserted through the cord gap 23b into the grooves of the cord holding parts 4b and 5b on both sides, and the winding body 25b is turned by the turning part 22b to form one bending ring part 13b around one bending ring shaft 20b between the one side cord holding part 4b and the other side cord holding part 5b, and the other bending ring part 14b around the other bending ring shaft 21b, forming one or more stages of spiral cord 15b around the one bending ring part 13b and the other bending ring part 14b, thereby storing the cord. The turning part 22b can be provided arbitrarily around both bending ring shafts including the lower side plate 19b.

As shown in Figure 7, the winding body 25b is formed integrally with the lower side plate 19b that fits rotatably into the retaining hole 18b, one bending axle 20b provided on the upper part, and the other bending axle 21b. The turning part 22b can also be provided on the lower side plate 19b side, but in this case it consists of an arm portion provided on the upper part of the other bending axle 21b side and a knob portion at its outer end. The turning part 22b extends outward from the center of the retaining hole 18b parallel to the upper plate surface 2b, and rotates along the upper surface of the spiral cord 15b during turning.

As shown in Figures 4 and 6, the cord is wound by turning the winding portion 22b in the right direction (clockwise direction) indicated by the arrow 27b. Figures 4 to 6 show the state of the spiral cord 15b in which the cord 6b has been wound in one stage. Here, the cord 6b is bent to form one bending ring portion 13b at one bending ring shaft 20b, and the other bending ring portion 14b is formed at the position of the other bending ring shaft 21b, so that the side that becomes one side 6ba of the cord and the side that becomes the other side 6bb of the cord are overlapped horizontally, and the one stage of the spiral cord 15b is formed by alternating overlapping around one bending ring portion 13b and the other bending ring portion 14b on the upper plate surface 2b, and the spiral cord is wound to form one stage. During the winding operation, one side portion 6ba of the cord 6b slides inward (to the right in the drawing) within the groove 7b of the one side cord holder 4b, and the other side portion 6bb of the cord 6b slides inward (to the left) within the groove 8b of the other side cord holder 5b, and is wound and stored in the cord storage device 1b and held on the base plate 3b around the holding hole 18b. The winding body 25b supports the center of the spiral cord with its one bending wheel shaft 20b and the other bending wheel shaft 21b, and the winding body 25b also serves as a spiral cord holding means. This is the same in the following embodiments equipped with a similar winding body.

Figures 8 to 10 show the spiral cords 15ba and 15bb in which the cord 6b has been wound up in two layers, one above the other. The height of both bending axles 20b and 21b can be determined according to the number of layers of the desired spiral cord. In this embodiment, the height of both bending axles 20b and 21b is approximately twice the height of the cord. Even with bending axles 20b and 21b with a cylindrical outer periphery as shown in the figure, when the winding body 25b is rotated and the bending cord portion of one bending ring portion 13b formed on one bending axle 20b reaches a position where it overlaps with the outside of the other bending ring portion 14b wound around the other bending axle 21b, the cord portion of one bending ring portion 13b can be lightly lifted with the fingertips or the like and guided to the upper layer, allowing the cord to be wound up in two layers, one above the other, with a slight operation at the beginning of winding.

The cord can be pulled out by pulling the left part 6ba and the right part 6bb of the cord 6b to the left or right. If the spiral cord 15b has a large number of turns, the cord can be pulled out more smoothly by pulling the left part 6ba and the right part 6bb of the cord 6b while turning the turning part 22b in the left direction (counterclockwise).

11 to 15 show a third embodiment of a cord storage device. The cord storage device 1j has a flat upper plate surface 2j and a base plate 3j with a certain thickness and a certain front-to-back width and left-to-right length, a one-side cord holding part 4j provided on one side of the upper plate surface 2j, a second-side cord holding part 5j provided on the other side of the upper plate surface 2j, a holding hole 18j for a winding body opened in the vertical direction at a position between the one-side cord holding part 4j and the other-side cord holding part 5j, and a certain width of the leading end and trailing end of the inner winding of each of the one-side cord holding part 4j and the other-side cord holding part 5j is wound on the upper plate surface 3j along the maximum outer curved surface of the spiral cord 15ja at a point exceeding the height of the cord 6j. the base body 34j having a one-side regulating wall 50j having a one-side inner edge 60j extending inward at its upper end and an other-side regulating wall 51j having an other-side inner edge 61j surrounding the cord 6j in an arc shape at a desired height, a lower side plate 19j that rotatably fits into the retaining hole 18j, one bending axle 20j and the other bending axle 21j that are formed side by side on the upper side at a desired height exceeding the height of the cord 6j by forming a cord gap 23j on the lower side plate with a spacing that exceeds the thickness of the cord, and a cord winding means of a winding body 25j consisting of a turning portion 22j provided at the end of both bending axles 20j and 21j including the lower side plate 19j. Therefore, one bending ring portion 13j is formed around one bending ring shaft 20j between one side cord holding portion 4j and the other side cord holding portion 5j, and the other bending ring portion 14j is formed around the other bending ring shaft 21j, and one or more stages of spiral cord 15 are formed around the one bending ring portion 13j and the other bending ring portion 14j to store the cord.

In the cord storage device 1j of the third embodiment, as shown in the figure, the one-side cord holding portion 4j and the other-side cord holding portion 5j are surrounded by a certain width at the front and rear of the inner windings of the one-side cord holding portion 4j and the other-side cord holding portion 5j, respectively, in an arc shape at a height approximately twice the height of the cord 6j on the upper plate surface 3j along the maximum outer curved surface of the spiral cord 15ja, and each is provided with a one-side regulating wall 50j having a one-side inner edge 60j and a other-side regulating wall 51j having a other-side inner edge 61j that extend inwardly parallel to the upper plate surface 3j at their upper ends. With the above configuration, the regulating walls 50j and 51j on both sides regulate the maximum outer diameter of the spiral cord between the cord holding portions 4j and 5j on both sides, and the one-side inner edge 60j and the other-side inner edge 61j work together with the cord holding portions 4j and 5j on both sides to effectively suppress and hold the outer main parts of the spiral cords 15ja and 15jb from floating up.

In this embodiment, the winding body 25j is provided with a cord upper/lower distribution means for distributing the bending ring portion to the upper side or lower side of a predetermined side of the bending wheel shaft on one side and the bending wheel shaft on the other side. In Figures 11 and 15, the winding body is provided with a cord lowering wing 42j that is provided on the side wall of the shaft on the leading side in the winding body rotation direction of the upper half of one bending wheel shaft 20j and that slopes down in a spiral in the reverse rotation direction of the winding body, and a cord raising wing 43j that is provided on the shaft side wall of the leading side in the winding body rotation direction of the lower half of the other bending wheel shaft 21j and that slopes up in a spiral in the reverse rotation direction of the winding body. When the winding body 25j is rotated clockwise by the rotation part 22j in the clockwise direction indicated by the arrow 27j, the cord lowering wing 42j on one bending wheel shaft 20j pushes down the cord 6jb' on the other side, leading it to the lower side of the bending wheel shaft 20j, and forms one bending ring part 13jb of the lower stage around one bending wheel shaft 20j. Meanwhile, the cord raising wing 43j on the other bending wheel shaft 21j pushes up the cord 6ja' on one side, leading it to the upper side of the other bending wheel shaft 21j, and forms the other bending ring part 14ja of the upper stage around the other bending wheel shaft 21j. In this way, the upper stage spiral cord 15ja and the lower stage spiral cord 15jb arranged in two stages are formed around the two bending ring parts, and the cords are guided to be stored. One bending axle 20j always has one bending ring portion 13jb in the lower row, and the other bending axle 21j always has the other bending ring portion 14ja in the upper row. This cord upper and lower distribution means is more effective for cords with an oval cross section, such as power cords.

In Figures 11 and 12, the grooves 7j and 8j of the one-side cord holding part 4j and the other-side cord holding part 5j are provided at the rear inner position of the windings, with rear rollers 33ja and 33jb rotatably fitted to a vertical shaft fixed to the substrate side. The groove 7j of the one-side cord holding part 4j is formed so that the groove wall on the leading side of the winding protrudes outward from the groove wall on the trailing side of the winding. The left extension of the inner edge 60j of the upper end of the one-side regulating wall 50j extends to the upper end of the groove wall on the leading side of the winding, and the upper end of the groove wall on the leading side of the winding has an inner edge 60j that protrudes shortly to the front. On the other hand, the left extension of the inner edge 60j of the front regulating wall 50j of the trailing side of the winding does not extend to the upper end of the groove wall on the trailing side of the winding. The rear groove wall side of the winding is provided with a rear roller 33ja rotatably fitted to a vertical shaft fixed to the substrate side, and opens straight upward. A gap is maintained between the front and rear groove walls of the groove 7j so that the cord 6j can pass upward. The shape of the groove 8j of the other cord holder 5j is rotated 180 degrees around the groove 7j of the one cord holder 4j at the center of the holder hole 18j. With the above configuration, the cord is guided to the rear rollers 33ja and 33jb, making it easier to wind and pull out the cord.

A stopper claw 46j is provided at one of the shaft ends under the lower side plate 19j of the winding body 25j, protruding outward. The stopper claw 46j has an inclined surface 76 that slopes downward toward the tip of the winding at the tip of the winding body rotation direction on the upper surface of the stopper claw 46j. On the other hand, a plurality of stopper grooves 45j are provided at equal intervals around the holding hole 18j on the base plate 3j side, into which the stopper claw 46j fits. Therefore, when inserting the winding body 25j into the holding hole 18j, the stopper claw 46j is inserted in line with one of the stopper grooves 45j. Normally, the stopper claw 46j is exposed on the back side of the base plate 3j as shown in Figure 12, and the winding operation is performed in that state. After winding the cord, the rotation of the winding body 25j is stopped by pinching the turning part 22j and slightly pulling the winding body 25j to fit the stopper claw 46j into the stopper groove 45j, and the rotation in the counter-winding direction can be stopped by pulling both ends of the cord. The above configuration makes it possible to prevent the winding body 25j from rotating without providing a separate anti-rotation means.

16 to 23 show a fourth embodiment of a cord storage device. Here, it is an embodiment for a solid cord. The cord storage device 1c includes a base plate 3c having a flat upper plate surface 2c and a constant thickness with a constant front-to-rear width and left-to-right length, a one-side cord holding portion 4c provided on one side of the upper plate surface 2c, an other-side cord holding portion 5c provided on the other side of the upper plate surface 2c, an upper cover portion 30c fixed on the base plate 3c, which covers the upper plate surface 2c at a desired height interval position that exceeds the height of the cord 6c on the upper plate surface 2c and has a cord through hole 36c with a width exceeding the thickness of the cord 6c in a straight line portion connecting the one-side cord holding portion 4c and the other-side cord holding portion 5c, a base plate body 34c having a holding hole 18c for a winding body opened in the vertical direction in the base plate 3c and the upper cover portion 30c at a position between the one-side cord holding portion 4c and the other-side cord holding portion 5c, and a holding hole 18c for a winding body opened in the vertical direction in the base plate body 34c. a lower side plate 19c that rotatably fits into the retaining hole 18c on the upper cover portion 30c side at a position above the lower side plate 19c that is spaced at a desired height greater than the height of the cord 6c; a cord gap 23c is formed in the center between the upper side plate 26c and the lower side plate 19c; one bending axle 20c and the other bending axle 21c that are arranged side by side in the diameter direction of both side plates, and a cord opening 37c that is opened with a width that exceeds the thickness of the cord 6c in a direction perpendicular to a straight line connecting the centers of both bending axles 20c and 21c at a position above the cord gap 23c of the upper side plate 26c; and a cord winding means for a winding body 25c that is rotatably held within the retaining hole 18c. Therefore, one bending ring portion 13cb is formed around one bending ring shaft 20c between the base plate 3c and the upper cover portion 30c between the one side cord holding portion 4c and the other side cord holding portion 5c, and between the lower side plate 19c and the upper side plate 26c, and the other bending ring portion 14ca is formed around the other bending ring shaft 21c, and one or more stages of spiral cords are formed around the one bending ring portion 13cb and the other bending ring portion 14ca, allowing cords to be stored.

Here, as shown in Figures 16 to 20, the cord 6c is passed through the cord hole 36c and fitted into the grooves of the cord holding parts 4c and 5c on both sides, and by rotating the turning part 22c of the winding body 25c, one of the lower bending ring parts 13c is formed around one bending ring shaft 20c between the one side cord holding part 4c and the other side cord holding part 5c, the other upper bending ring part 14c is formed around the other bending ring shaft 21c, a lower tier spiral cord 15cb is formed around the one bending ring part 13c, and an upper tier spiral cord 15ca is formed around the other bending ring part 14c, thereby storing the cord.
Here, cylindrical rear rollers 33ca and 33cb and front rollers 32ca and 32cb are used in the groove of the cord holding part. Therefore, it is easy to lift one side 6ca of the cord. Even if the bending wheel shafts 20c and 21c have a cylindrical outer circumference as shown in the figure, when the bending cord part of one bending wheel part 13c formed on one bending wheel shaft 20c is in a position overlapping with the outside of the other bending wheel part 14c wound around the other bending wheel shaft 21c approaching due to the rotation of the winding body when the winding body is rotated, the one side 6ca of the cord can be reliably wound in two stages by a slight operation at the beginning of winding, such as lifting one side 6ca of the cord a little and guiding it to the upper stage.
This configuration makes it possible to obtain a cord storage device with a simple structure capable of securely storing two tiers of spiral cords, one above the other, in a thin, flat storage section.

The upper cover part 30c is integrally connected to the base plate part 3c by four support pillars 35c on the front, rear, left and right sides, and is integral with the base plate part 3c. The upper cover part 30c has cord through holes 36c that allow the cord 6c to pass through sufficiently on the groove 7c side between the two front and rear rollers 32ca and 33ca of the cord holding part 4c on one side and on the groove 8c side between the two front and rear rollers 32cb and 33cb of the cord holding part 5c on the other side, and the cord 6c that is stretched straight from above the upper cover part 30c and has a length that exceeds the outside of the grooves 7c and 8c of both the cord holding parts 4c and 5c can be passed through the cord through holes 36c and placed on the upper plate surface 2c of the base plate part 3c with the cord opening 37c of the reel 25c aligned.
With this configuration, the upper cover portion 30c covers a wide area of the upper surface of the spiral cord between itself and the upper plate surface 2c, and serves to prevent the cord from sticking out upward.

In this embodiment, the groove 7c of the cord holding portion 4c on one side is open at the top, and is made up of a leading roller 32ca at the leading position of the winding outside the groove 7c and a rear roller 33ca at the rear position of the winding inside the groove 7c, which are rotatably held on a roller shaft 31c fixed to the base body 34c side on both the front and rear sides of the groove 7c. The cord holding portion 5c on the other side is also made up of a leading roller 32cb at the leading position of the winding outside the groove 8c, which are rotatably held on a roller shaft 31c fixed to the base body 34c side, and a rear roller 33cb at the rear position of the winding inside the groove 8c. The rear rollers 33ca and 33cb are provided with a rear roller 33ca at the rear of the winding inside the groove 7c and groove 8c, which are spaced apart from the leading rollers 32ca and 32cb by a certain distance on the inside. As a result, one side 6ca of the cord and the other side 6cb of the cord extending from the spiral cord 15c side are bent at the positions of the cord holding parts 4c and 5c, and the cord 6c is led out straight to both sides. The outer periphery of each roller is cylindrical, and the movement of the cord 6c in the vertical direction is restricted by the upper plate surface 2c and the upper cover part 30c.

As shown in FIG. 21, the winding body 25c is arranged with one bending axle 20c and the other bending axle 21c spaced apart at equal intervals from the center of the lower side plate 19c between the lower side plate 19c and the upper side plate 26c, and a cord hole 37c through which the cord 6c passes is opened on the upper side plate 26c side. The winding body 25c is provided with a rotation section 22c consisting of two holes that penetrate from the upper side plate 26c side to the lower side plate 19c side. The rotation section 22c is made up of two holes that penetrate through both bending axles 20c and 21c from the upper surface of the upper side plate 63c to the lower surface of the lower side plate 62c. The first and second fingers of the hand are placed on the ends of the rotation section 22c consisting of the two holes, and the winding body 25c can be rotated clockwise as shown by the arrow 27c to wind up the cord 6c.

Figure 28 shows the winding handle 28d of the fifth embodiment, which will be described later. The two shafts 29d of the winding handle 28d also fit into the two holes of the turning part 22c of the fourth embodiment, and the two shafts 29d of the winding handle 28d can be inserted into the two holes of the turning part 22c to turn the winding body 25c and wind up the cord 6c.

The cord 6c can be stored by passing it through the cord hole 36c and the grooves 7c and 8c and placing it on the upper plate surface 2b of the base body 34c, then rotating the winding body 25c in a clockwise direction. This configuration makes it easy to attach and store the cord while wiring. The cord can be pulled out by pulling one side portion 6ca and the other side portion 6cb of the cord 6c outward. Here, front rollers 32ca and 32cb and rear rollers 33ca and 33cb are attached to the front and rear sides of the grooves 7c and 8c of both cord holding parts, and the winding and pulling operations can be performed smoothly without rotating the turning part 22c to apply force.

Figures 22 and 23 show an embodiment in which another power cord 6cc is stored in the cord storage device 1c. The power cord 6cc has the same oval cross-sectional shape as that used in the first embodiment, and the height of the power cord 6cc is less than the gap between the base plate 3c and the upper cover part 30c of the cord storage device 1c. The figures show the state of the spiral cord in which the cord 6cc has been wound to the maximum winding limit. Here, as in the example of the single-stage winding in the second embodiment described above, the cord 6cc is bent to form one bending loop part 13c at one bending loop axis 20c, and the other bending loop part 14c is formed at the other bending loop axis 21c, so that the side that becomes one side of the cord 6cca and the other side of the cord 6ccb are overlapped, and the spiral cord 15c is formed and wound in the space between the upper plate surface 2c and the upper cover part 30c, with the one bending loop part 13c and the other bending loop part 14c overlapping each other. During the winding operation, one side portion 6cca of the cord 6cc slides inward within the groove 7c of the one side cord holder 4c, and the other side portion 6ccb of the cord 6cc slides inward within the groove 8c of the other side cord holder 5c, and is wound and stored in the cord storage device 1c. This configuration makes it possible to obtain a cord storage device with a simple structure that can securely store one layer of spirally wound cord in a thin, flat storage section.

Figures 24 to 28 show a fifth embodiment of a cord storage device. Here, an example of a cord storage device for tubes and hoses is shown, in which the cords are stored as two spiral cords, one above the other. The cord storage device 1d shown in the fifth embodiment comprises a base plate 3d having a flat upper plate surface 2d and a constant thickness with a constant front-to-rear width and left-to-right length, a first cord holding portion 4d provided on one side of the upper plate surface 2d, a second cord holding portion 5d provided on the other side of the upper plate surface 2d, an upper cover portion 30d fixed to the base plate 3d and provided with a cord through hole 36d of a width exceeding the thickness of the cord 6d in a linear portion connecting the first cord holding portion 4d and the second cord holding portion 5d at a distance of a desired height exceeding the height of the cord 6d on the upper plate surface 2d, an upper cover portion 30d located between the first cord holding portion 4d and the second cord holding portion 5d, and a holding hole 18d for a winding body 25d formed in the base plate 3d, and a base body 34d having an outer diameter exceeding the front-to-rear width of the base plate 3d and rotatably fitted into the holding hole 18d on the base plate 3d side. the upper side plate 63d has an outer diameter exceeding the front-to-rear width of the base body 34d and is rotatably fitted into a retaining hole 18d on the upper cover portion 30d side, and a cord gap 23d is formed in the center between the upper and lower side plates, and one bending axle 20d and the other bending axle 21d are arranged side by side in the diameter direction of the upper and lower side plates, and a cord opening 37d is opened at a position above the cord gap 23d of the upper side plate 63d, with a width exceeding the thickness of the cord 6d in a direction perpendicular to the straight line connecting the centers of the two bending axles 20d and 21d, and Therefore, one bending ring portion 13db is formed around one bending ring axle 20d between the lower side plate 62d and the upper side plate 63d between the one side cord holding portion 4d and the other side cord holding portion 5d, and the other bending ring portion 14da is formed around the other bending ring axle 21d, and one or more stages of spiral cords are formed around the one bending ring portion 13db and the other bending ring portion 14da to store cords. In the figure of this embodiment, the lower guide protrusion 38d and the upper guide protrusion 39d are provided on the lower side plate 62d and the upper side plate 63d near the one bending ring axle 20d and the other bending ring axle 21d of the winding body 25d, but by using a winding body that does not have the upper and lower distribution means, it is possible to wind one or more stages in the same way as in the fourth embodiment described above.

Two front rollers 32da and two rear rollers 33da are provided in front of and behind the groove 7d of the left cord holding part 4d, each of which is rotatably held by a roller shaft 31d fixed to the base body 34d side, and two front rollers 32db and two rear rollers 33db are provided in front of and behind the groove 8d of the right cord holding part 5d, each of which is rotatably held by a roller shaft 31d fixed to the base body 34d side. The two front rollers and the rear rollers on each side have a cylindrical outer periphery and are arranged in a roughly juxtaposed manner in the left-right direction in front of and behind the grooves on the left and right sides. As a result, the left side of the cord 6da and the right side of the cord 6db are led out straight in the left-right direction at the positions of the cord holding parts 4d and 5d, regardless of the winding direction of the spiral cords 15da and 15db. The movement of the cords 6da and 6db in the vertical direction is suppressed by the upper plate surface 2d and the upper cover part 30d. The upper cover part 30d is connected to the base part 3d by four pillars 35d on the front, rear, left and right sides, and is fixed integrally to the base body 34d. The upper cover part 30d has a cord passage hole 36d that opens straight to the groove 7d side between the two front and rear rollers 32da and two 33da of the left cord holding part 4d, and to the groove 8d side between the two front and rear rollers 32db and two 33db of the right cord holding part 5d.

Figure 27 shows the roll-up body 25d. In Figures 24 to 27, the outer diameter of the disk-shaped upper side plate 63d and lower side plate 62d of the roll-up body 25d is larger than the front-to-rear width of the substrate 3d and the upper cover part 30d, and the lower side plate 62d side is rotatably held in a retaining hole 18d formed in a recessed shape along the outer diameter and thickness of the lower side plate 62d on the inside (upper side) of the upper plate surface 2d of the substrate 3d. One upper side plate 63d is rotatably held by the part of the partially circular retaining hole 18d on the left and right sides cut out along the outer diameter of the upper side plate 63d at the center of the upper cover part 30d. The vertical distance between the upper side plate 63d and the lower side plate 62d approximately matches the distance between the upper plate surface 2d and the upper cover part 30d. A cord opening 37d is provided in the center of the upper side plate 63d in the diameter direction to allow the cord 6d to pass through at the beginning of winding. The cord opening 37d of the winding body 25d is oriented in the direction of the cord through hole 36d, and the cord 6d can be inserted from above the upper cover part 30d through the cord through hole 36d and the cord opening 37d into the groove 7d of the cord holder 4d on one side and the groove 8d of the cord holder 5d on the other side.

The turning part 22d here is made up of two holes that penetrate through both bending wheel axles 20d and 21d from the top side of the upper side plate 63d to the bottom side of the lower side plate 62d. The first and second fingers of the hand are placed on the ends of the turning part 22d, which consists of the two holes, and the winding body 25d can be turned to the right to wind up the cord 6d. The winding handle 28d is shown in Figure 28. The two shafts 29d of the winding handle 28d fit into the two holes of the turning part 22d, and the two shafts 29d of the winding handle 28d can be inserted into the two holes of the turning part 22d to turn the winding body 25d to wind up the cord 6d. In addition, the turning parts for turning the winding body 25d can be provided in any shape at any position on the upper and lower side plates.

In the fifth embodiment, as shown in Figures 24 to 27, a distribution means is provided for distributing two bending ring parts bent by two bending axles to the upper and lower sides within a vertical space that is more than twice the height of the cord 6d on the upper plate surface 2d. The winding body 25d is provided with a downward guide protrusion 38d that protrudes downward in a mountain-like shape on both the front and rear sides of the cord opening 37d on one side (right side) of one bending axle 20d and the other bending axle 21d on the lower surface side of the upper side plate 63d, and an upward guide protrusion 39d that protrudes upward in a mountain-like shape at a position that corresponds to both the front and rear sides of the cord opening 37d on the upper side plate 63d side on the other side (left side) of one bending axle 20d and the other bending axle 21d on the upper surface side of the lower side plate 62d.

Therefore, by rotating the winding body 25db, the right-side cord 6db of the cord 6d is pushed downward by the lower guide protrusion 38d to form one bending ring portion 13db at a position below one of the bending wheel shafts 20d, and the left-side cord 6da of the cord 6d is pushed upward by the upper guide protrusion 39d to form the other bending ring portion 14da at a position above the other bending wheel shaft 21d, thereby forming and storing an upper tier spiral cord 15da and a lower tier spiral cord 15db arranged side by side in two tiers, one above the other, around both bending ring portions. The lower guide protrusion 38d and upper guide protrusion 39d of the upper and lower cord distribution means shown here are provided on both the front and rear sides of the cord opening 37d on the left and right sides of both bending axles 20d and 21d, and have the characteristic of having an upper and lower distribution function that distributes the cord 6db on the right side of the cord 6d downward and the cord 6da on the left side of the cord 6d upward regardless of the direction of rotation of the winding body 25db.

In this way, the cord 6d is divided into two parts, one above the other, around the bending axle 20d and the other bending axle 21d, forming a spiral cord arranged side by side. Figures 25 and 26 show the state of the spiral cords 15da and 15db that have been wound in two parts, one above the other. The method of dividing the cords into upper and lower parts shown here is also effective for cords that are easily twisted, such as hollow tubes.

The feature of the fifth embodiment, with the above-mentioned configuration, is that, except for the outer part of the spiral cord, the main inner spiral cord part rotates together with the upper and lower side plates of the winding body 25d, and no sliding friction occurs between the spiral cord and the inner surfaces of the upper and lower side plates. This eliminates sliding between the cord 6d and the inner surface of the side plates, making the winding body 25d rotate more smoothly, and reducing wear and tear on the cord 6d.

The cord storage device 1d shown here is the same as the fourth embodiment described above, in that the upper cover part 30d is fixed to the base part so as to cover the upper plate surface 2d at a distance greater than the height of the cord, and has an upper cover part with a cord passage hole with a width greater than the thickness of the cord in the straight line portion connecting the one side cord holding part and the other side cord holding part 5, and a base body having a holding hole for a winding body in the upper cover part and base body at a position between the one side cord holding part and the other side cord holding part, and a circular upper side plate that fits into the holding hole on the upper cover part side of the base body, a circular lower side plate that fits into the holding hole on the upper plate surface side, and one bending ring that is arranged side by side to form a cord gap in the central position between the upper and lower side plates. The cord storage device has a shaft and the other bending wheel shaft, a cord opening with a width greater than the thickness of the cord that is opened in a direction perpendicular to the straight line connecting the centers of the two bending wheel shafts at a position above the cord gap of the upper side plate, and a cord winding means for a winding body that has a rotating part provided on at least one side of the upper side plate and the lower side plate and is rotatably held in the holding hole, and can be implemented as a cord storage device that forms one bending ring part around one bending wheel shaft between the one side cord holding part and the other side cord holding part, forms the other bending ring part around the other bending wheel shaft, and forms a one-stage spiral cord around it to store the cord, and can obtain the same effect as the one-stage winding of the fourth embodiment described above.

24 to 27, the cord storage device 1d of the fifth embodiment is provided with a number of sawtooth grooves 45d evenly spaced around the outer periphery of the upper side plate 63d of the reel, a retaining hole for a stopper body 46d provided on one side of the upper cover part 30d around the upper side plate 63d, and a stopper body 46d that fits rotatably into the retaining hole and has a hook part 48d at its front that can be hooked and detached from the groove of the sawtooth groove 45d and an operating lever part extending rearward at its rear side. The stopper body 46d fits rotatably in a retaining hole that is a shallow recess on the top surface of the upper cover part 30d, and can be swung in a fan shape around the retaining hole by operating the operating lever part at the rear with the fingertips as shown by arrow 47d. Therefore, by rotating the winding body 25d in the right (clockwise) direction while pushing the lever part of the stopper 46d in the right (clockwise) direction, the hook part 48d can be engaged with the groove of the sawtooth groove 45d, and the counterclockwise rotation of the winding body 25d can be stopped even if you release the winding. This stops the movement in the direction to pull out the cord, and prevents the taut cord from loosening.

Figures 29 to 34 show a sixth embodiment. Here, an embodiment of a cord storage device for tubes and hoses is shown. The cord storage device 1e comprises a base plate 3e having a flat upper plate surface 2e and a constant thickness with a constant front-to-back width and left-to-right length, a one-side cord holding portion 4e on one side of the upper plate surface 2e, a other-side cord holding portion 5e on the other side of the upper plate surface 2e, a holding hole 18e for a reel body opened in the vertical direction at a position between the one-side cord holding portion 4e and the other-side cord holding portion 5e, a lower side plate 19e that fits rotatably into the holding hole 18e, and a lower side plate 19e that is concentric with the lower side plate 19e at a distance above the lower side plate 19e at a desired height that exceeds the height of the cord (here, twice the height of the cord). The bending axle 20e and the other bending axle 21e are arranged side by side in the diameter direction of the upper and lower side plates, with a cord gap 23e formed in the center between an upper side plate 26e and the upper and lower side plates, a cord opening 37e opened at an upper position above the cord gap 23e of the upper side plate 26e in a direction perpendicular to the straight line connecting the centers of the two bending axles 20e and 21e, and a rotating portion 22e provided on at least one side of the upper and lower side plates, and a cord winding means for a winding body 25e held rotatably within the retaining hole 18e. Therefore, between the one side cord holding part 4e and the other side cord holding part 5e, one bending ring part 13eb in the lower stage is formed around one bending ring shaft 20e, and the other bending ring part 14ea in the upper stage is formed around the other bending ring shaft 21e, and the spiral cords 15ea and 15eb arranged side by side in two stages, upper and lower, are formed and stored around the one bending ring part 13eb and the other bending ring part 14ea.

The upper side plate 26e rotates parallel to the upper plate surface 2e of the base plate 3e during the winding operation to prevent the spiral cord 15ea from floating upward. Here, the turning part 22e that turns the winding body 25e is provided at one end of the upper side plate 26e.

In Figures 31 and 32, the cord holding section 4e on one side has a holding groove 75ea at the top of the winding, with the lower end of each held rotatably by a roller shaft 31e fixed to the base plate 3e on both the front and rear sides of the groove 7e, and is made up of a leading roller 32ea at the leading end of the winding on the outside of the groove 7e, and a rear roller 33ea at the rear end of the winding on the inside of the groove 7e. The cord holding section 5e on the other side also has a holding groove 75ea at the bottom of the winding, with the lower end of each held rotatably by a roller shaft 31e fixed to the base plate 3e on both the front and rear sides of the groove 8e, and is made up of a leading roller 32eb at the leading end of the winding on the outside of the groove 8e, and a rear roller 33eb at the rear end of the winding on the inside of the groove 8e.

The retaining grooves 75ea of the rollers of both cord retaining parts 4e and 5e are composed of approximately semicircular recessed grooves that match the circular cross section of the cord. The front roller 32ea and rear roller 33ea of one cord retaining part 4e have retaining grooves 75ea at the upper stage of the winding, and retain one side 6ea of the cord at the upper stage of the winding. The front roller 32eb and rear roller 33eb of the other cord retaining part 5e have retaining grooves 75eb at the lower stage of the winding, and retain the other side 6eb of the cord at the lower stage of the winding. The retaining grooves 75ea and 75eb serve to hold the cords firmly in their positions and at the same time to relieve the strain on the cords (tubes) at the bent part. Here, the retaining groove 75ea serves to hold one side 6ea of the cord on the one cord retaining part 4e side at the upper stage of the winding and guide it to the upper stage around the other bending wheel shaft 21e to help form the other bending wheel part 14ea on the upper stage side. In addition, the retaining groove 75eb retains the other side 6eb of the cord on the other side cord retaining portion 5e side in a position on the lower side of the winding, guiding it to the lower side around one bending wheel shaft 20e and helping to form one bending wheel portion 13eb on the lower side.

In this embodiment, both bending axles of the winding body 25e are provided with cord retaining grooves 40e and 41e on the cord winding side, which are recessed in a shape that matches the cross-sectional shape of the cord. A cord retaining groove 40e recessed in a shape that matches the cross-sectional shape of the cord is provided above and below the cord winding side of one bending axle 20, and a cord retaining groove 41e recessed in a shape that matches the cross-sectional shape of the cord is provided above and below the cord winding side of the other bending axle 21e. The cord retaining grooves serve to prevent twisting of the cord wound around the bending axle. By providing cord retaining grooves such as the cord retaining groove 40e and the cord retaining groove 41e around one bending axle 20e and the other bending axle 21e of a cord storage device that winds up tubes and hoses, twisting of tubes and hoses at the bending axle portion can be prevented.

In the fourth embodiment of the cord storage device, a separate rotation stopper is provided to stop the rotation of the winding body 25e. Pin receiving holes 45e are provided at equal intervals on a circumference around the retaining hole 18e of the base plate 3e. Meanwhile, at the circumferential position where the pin receiving hole 45e is located in the bending wheel axle of the winding body 25e (here, the other bending wheel axle 21e), an axial hole is opened that penetrates from the upper end to the lower end of the axle, and a stop pin 46e that can slide up and down is fitted into the axial hole. The stop pin 46e has an operating knob 48e on its upper part, and the stop pin 46e can be operated up and down by pinching the knob 48e. Therefore, while winding the winding body 25e, the stop pin 46e is pulled up, and when the rotation part 22e is at the desired rotation position, the knob 48e is pushed down as shown by the arrow 47e to insert the tip of the stop pin 46e into the pin receiving hole 45e of the base plate 3e, thereby stopping the rotation of the winding body 25e. This stops the movement in the direction to pull out the cord, and prevents the tensioned cord from loosening. The rotation part 22e that turns the winding body 25e can be installed at the desired position around both bending wheel shafts 20e and 21e and the lower side plate 19e.

Figures 35 to 37 show a seventh embodiment of a cord storage device. In this cord storage device 1s, the cord is wound in two or more stages. The cord storage device 1s comprises a base plate 3s having a flat upper plate surface 2s and a constant thickness with a constant front-to-back width and left-to-right length, a one-side cord holding part 4s provided on one side of the upper plate surface 2s, an other-side cord holding part 5s provided on the other side of the upper plate surface 2s, a holding hole 18s for a winding body provided at a position between the one-side cord holding part 4s and the other-side cord holding part 5s on the upper plate surface 2s, a disk-shaped lower side plate 62s that fits rotatably within the holding hole 18s, and a disk-shaped lower side plate 62s that is formed concentrically with the lower side plate 62s at a desired height above the lower side plate 62s and spaced apart from the lower side plate 62s. The upper side plate 63s has a cord gap 23s in the center between the upper and lower side plates, one bending axle 20s and the other bending axle 21d arranged side by side in the diameter direction of the upper and lower side plates, a cord opening 37 opened at a width exceeding the thickness of the cord 6s in a direction perpendicular to the straight line connecting the centers of the two bending axles 20s and 21s on the upper side of the cord gap 23s of the upper side plate 63s, and a turning part 22s provided on at least one side of the upper and lower side plates, and a cord winding means for a winding body 25s rotatably held in the holding hole 18s.

Therefore, in the same manner as in the previous embodiment, by rotating the winding body 25s, one bending ring portion 13sb is formed around one bending ring shaft 20s between the one side cord holding portion 4s and the other side cord holding portion 5s, and the other bending ring portion 14sa is formed around the other bending ring shaft 21s, and one or more stages of spiral cord 15sb are formed around the one bending ring portion 13sb and the other bending ring portion 14sa, thereby allowing cords to be stored.

Here, the two front rollers and the two rear rollers on the inside and outside of the one-side cord holding part 4s and the other-side cord holding part 5s are also of a length that matches the distance between the lower side plate 62s and the upper side plate 63s. Furthermore, here, the leading roller 32sa at the tip of the spiral cord winding on the outside (one side) of the one-side cord holding part and the rear roller 33sa at the rear of the inner (other side) winding are provided with a flange 70sa that protrudes outward at a position that matches the lower surface of the upper side plate 63s. In addition, the leading roller 32sb at the tip of the outer (other side) winding of the other-side cord holding part and the rear roller 33sb at the rear of the inner (one side) winding are also provided with a flange 70sb that protrudes outward at a position that matches the lower surface of the upper side plate 63s. As a result, the cord 6s is wound in the direction of the arrow 27s by the winding body 25s, just like the two cord holding sections 4a and 5a in the cord storage device 1a of the first embodiment, forming a cord holding means that prevents one side 6sa of the cord and the other side 6sb of the cord from escaping upward and holds them firmly in place.

The operation of removing the one side portion 6sa and the other side portion 6sb of the cord 6s from the grooves 7s and 8s of the one side cord holding portion 4s and the other side cord holding portion 5s, and the operation of fitting the cord 6s into the grooves 7s and 8s can be performed in the same manner as in the cord storage device 1a of the first embodiment. The winding body 25s has a button-shaped turning portion 22s on one side of the upper part of the upper side plate 63s. The winding body 25s can be turned securely by the turning portion 22s.

By the rotation of the winding body 25s, one side 6sa of the cord is held by the front roller 32sa and the rear roller 33sa, and the other side 6sb of the cord is held by the front roller 32sb and the rear roller 33sb, and moves between the lower side plate 62s side and the upper side plate 63s side toward one bending wheel shaft 20s and the other bending wheel shaft 21s, and the winding position of the cord 6s around one bending wheel shaft 20s and the other bending wheel shaft 21s is naturally distributed up and down to form a spiral cord 15s that is wound. The shape of the cord winding here is not a neat spiral winding as shown in Figures 31 to 32 of the sixth embodiment, but a scattered spiral winding. With this configuration, by taking the distance between the lower side plate 62s and the upper side plate 63s to be multiple times more than twice the height of the cord 6d, a longer length of cord can be stored by winding it in a scattered manner. It can be made into a cord storage device that is suitable for storing relatively thin and long cords.

The seventh embodiment can be implemented so that the cord is wound into a single spiral cord as shown in FIG. 6 of the second embodiment described above by selecting the desired spacing between the lower side plate 62s and the upper side plate 63s. Also, by configuring the spacing between the lower side plate 62s and the upper side plate 63s in a manner similar to that of the fourth to sixth embodiments, the cord can be wound into two spiral cords, one above the other. When winding and unwinding the cord, the cord storage device 1s rotates the entire spiral cord together with the upper and lower side plates between the cord holding portion on one side and the cord holding portion on the other side, so that no sliding friction occurs between the cord and the storage wall surface. This allows for smooth winding and unwinding. Furthermore, the cord is not damaged or damaged by sliding.

The method of forming a first bending loop and a second bending loop between the one side cord holding part and the other side cord holding part on the upper plate surface and winding up a single cord into a spiral cord includes a method of holding a single cord between the one side cord holding part and the other side cord holding part, as shown in the above example, forming a first bending loop and a second bending loop between them, and winding the inside of the two windings by rotating the fingers of a hand or one bending ring shaft and the other bending ring shaft, as shown in the following example, fixing one bending ring shaft and the other bending ring shaft, winding the two folded cords on the outside of the winding around one bending ring shaft and the other bending ring shaft, and winding up the two folded cords into a spiral cord, and holding the two folded cords in the one side cord holding part and the other cord holding part, respectively.

The latter embodiment is shown below. Figures 38 to 41 show an eighth embodiment of a cord storage device. This cord storage device 1f has a flat upper plate surface 2f, a base plate 3f of a certain thickness with a certain front-to-back width and left-to-right length, a one-side cord holding part 4f provided on one side of the upper plate surface 2f, an other-side cord holding part 5f provided on the other side of the upper plate surface 2f, one bending wheel axle 16f and the other bending wheel axle 17f that protrude upward to a height that matches the height of the cord provided at a certain interval on one side and the other side of a position between the one-side cord holding part 4f and the other-side cord holding part 5f, and an outer cord manual winding means 25f. Between the one side cord holding part 4f and the other side cord holding part 5f, one bending ring part 13f is formed around one bending ring shaft 16f, and the other bending ring part 14f is formed around the other bending ring shaft 17f, and a spiral cord 15f is formed around the one bending ring part 13f and the other bending ring part 14f to store the cord.

Here, the groove 7f of one side cord holding portion 4f has a shorter left-right length than that of the first embodiment described above, and the side forming the rear wall of the groove 7f is formed to be shifted inward from the side forming the front wall of the groove 7f. The groove wall on the rear side of the turn is open straight in the vertical direction. On the other hand, the groove wall on the side forming the front wall of the turn is formed in a recessed shape that roughly follows the shape of the peripheral wall of the cross section of the cord 6f, with its upper part protruding inward of the groove. Again, a gap is maintained between the front and rear walls of groove 7f that allows the cord 6f to pass through.

The groove 8f of the other side cord holder 5f has a shape obtained by rotating the groove 7f of the one side cord holder 4f by 180° on the plane of the front view, and functions in the same way as the groove 7f of the one side cord holder 4f. Therefore, the operation of fitting one side 6fa and the other side 6fb of the cord 6f into and removing it from the one side cord holder 4f and the other side cord holder 5f can be performed in the same way as in the first embodiment described above.

In this embodiment, a different winding means for the cord 6f from that in the first embodiment is shown. In FIG. 38, the cord is folded and the inside of one bending loop portion 13f is hung on one bending loop shaft 16f, and the two folded cord portions are overlapped front and back to form a cord 6f' that is stretched to the other side, and held in the hand. While maintaining the overlapped state, the cord is wound counterclockwise around the other bending loop shaft 17f as shown by the arrow 27f to form the other bending loop portion 14f, and is further wound around the outside of one bending loop portion 13f on the one bending loop shaft 16f side to overlap, forming a spiral shape in which one side and the other side of the folded portion of one bending loop portion 13f are alternately overlapped, forming a spiral cord 15f. Here, this winding method is called the cord outer manual winding means 25f.

In Figure 38, the outer cord 6fb of the overlapped cords advances toward the other side cord holding part 4b located on the other side, fits into its groove 8f, and is led out to the other side as the other side of the cord 6fb. Meanwhile, the inner cord of the overlapped cords is wound around to the outer position of one bending ring part 13f on one bending ring shaft 1f side, and then immediately advances toward the one side cord holding part 4f on one side, fits into the groove 7f of the one side cord holding part 4f, and is led out to one side as one side of the cord 6fa. Here, the state with the shortest winding length is shown.

Figure 41 shows the state in which the cord 6f is fully wound inside the cord storage device 1f. In this eighth embodiment, one bending axle 16f and the other bending axle 17f are spaced apart from each other on one side and the other, so the shape of the spiral cord 15f is an ellipse that is long on one side and the other, which is a preferable shape for storing a cord storage device attached to the middle of a wiring cord. In addition, the spiral cord 15f is held by one bending axle 16f and the other bending axle 17f fixed on the upper plate surface 2f of the base plate 3f, and both bending axles 16f and 17f function as a spiral cord holding means.

42 to 45 show a ninth embodiment of a cord storage device. This cord storage device 1g includes a base plate 3g having a flat upper plate surface 2g and a fixed thickness with a fixed front-to-back width and left-to-right length, a one-side cord holding part 4g provided on one side of the upper plate surface 2g, an other-side cord holding part 5g provided on the other side of the upper plate surface 2g, one bending axle 16g and the other bending axle 17g provided at a fixed interval on one side and the other side of a position between the one-side cord holding part 4g and the other-side cord holding part 5g, protruding upward to a height that matches twice the height of the cord, and a cord winding means of an upper and lower outer hand winding means 25g.
One bending ring portion 13gb and the other bending ring portion 14ga are formed around one bending ring shaft 16g and the other bending ring shaft 17g between one side cord holding portion 4g and the other side cord holding portion 5g, and two upper and lower layers of spiral cords 15ga and 15gb are formed around the one bending ring portion 13gb and the other bending ring portion 14ga to store the cords.

Here, the one-side cord holding portion 4g and the other-side cord holding portion 5g are substantially the same as those in the eighth embodiment described above. The operation of attaching and detaching the one-side portion 6ga and the other-side portion 6gb of the cord 6g to and from the two cord holding portions 4g and 5g can be performed in the same manner as in the first and eighth embodiments described above. In this embodiment, a winding means for the cord 6g different from that in the eighth embodiment described above and spiral cords 15ga and 15gb consisting of two layers, upper and lower, are shown.

In Figure 42, the cord is folded and the inside of one bending loop portion 13g is hung on one bending loop shaft 16g, and the two folded cord portions are stacked vertically with one side on top and the other side on the bottom to form a cord 6g', which is held in the hand, and while maintaining the stacked state, the cord is wound counterclockwise around the other bending loop shaft 17g as shown by arrow 27g with the same hand to form the other bending loop portion 14g in two layers, upper and lower, and further wound around one bending loop shaft 16g on the left side to form the upper and lower two layers of spiral cord 15ga and spiral cord 15gb.

There is another way to wind the cord outer upper and lower hand winding means 25g. In this method, the lower cord of the cord 6g' that is stacked on top of one another is first wound around the other bending wheel shaft 17g and one bending wheel shaft 16g to form the lower spiral cord 15gb, which is then fitted and held in the holding groove 7g or 8g of the one side cord holding part 4g or the other side cord holding part 5g, and then the upper cord of the cord 6g' is wound around the other bending wheel shaft 17g and one bending wheel shaft 16g to form the upper spiral cord 15ga, which is then fitted and held in the holding groove of the vacant cord holding part.

In FIG. 42, the upper cord 6ga of the overlapped cords is wound around the upper side of the other bending wheel shaft 17g, passes through the front side of one bending wheel shaft 16g on the left side toward the one side cord holding part 4g, is fitted into the groove 7g of the one side cord holding part 4g, and is led out to one side as the other side 6ga of the cord. On the other hand, the lower cord 6gb of the overlapped cords forms the lower other bending wheel part 14g around the other bending wheel shaft 17g, then goes around the outside of the lower one bending wheel part 13g of the left one bending wheel shaft 16g in a counterclockwise direction, passes through the rear side (near side) of the other bending wheel part 14g of the other bending wheel shaft 17g on the right side, immediately toward the other side cord holding part 5g on the other side, is fitted into the groove 8g of the other side cord holding part 5g, and is led out to the other side as the other side 6gb of the cord, showing a state in which the cords are wound in two layers, up and down.

Figure 45 shows the state in which the cord 6g is fully wound inside the cord storage device 1g. Here, the upper spiral cord 15ga at the beginning of winding in Figure 42 is guided to the groove 8g of the other side cord holding part 5g and led out to the other side from the other side cord holding part 5g, and the lower spiral cord 15gb is guided to the groove 7g of the one side cord holding part 4g and led out to one side from the one side cord holding part 4g. One bending wheel shaft 16g and the other bending wheel shaft 17g provided on the upper plate surface 2g have a recessed holding groove 40g with a vertical width corresponding to the upper and lower sides of the cord 6g on the outer periphery slightly below the upper end of the shaft. This more effectively prevents the one bending wheel part 13g and the other bending wheel part 14g wound around the shaft from floating up and coming off the shaft. In this eighth embodiment, one bending axle 16g and the other bending axle 17g are spaced apart from each other, so the shape of the spiral cord 15g is close to an ellipse that is long on both sides. This is a cord storage device with excellent storage efficiency, which is advantageous for attaching it to the middle of a wiring cord.

Figures 46 to 50 show a tenth embodiment of a cord storage device. This cord storage device 1h includes a base plate having a flat upper plate surface 2h and a constant thickness with a constant front-to-rear width and left-to-right length, a left cord holding part provided on the left side of the upper plate surface, a right cord holding part provided on the right side of the upper plate surface, a front restricting wall 50h extending in the left-to-right direction at a height of less than twice the height of the cord 6h at the front end of the upper plate surface 2h, a rear restricting wall 51h extending in the left-to-right direction parallel to the front restricting wall 50h at a height matching the height of the front restricting wall 50h at the rear end of the upper plate surface 2h, one bending wheel axle 16h provided at a position on the left between the left and right cord holding parts 4h and 5h on the upper plate surface 2h and protruding upward to a height of less than twice the height of the cord 6h, and the left and right cords on the upper plate surface 2h. The other bending axle 17h is provided on the right side between the cord holding parts 4h and 5h and protrudes upward to a height that matches the height of the one bending axle 16h, and a cord winding means for the cord outer manual winding means winds the cord 6h around the one bending axle 16h and the other bending axle 17h. One bending ring part 13h is formed around one bending axle 16h between the left cord holding part 4h and the right cord holding part 5h, and the other bending ring part 14h is formed around the other bending axle 17h. The cord can be stored by forming a spiral cord of the desired number of stages (one or two) inside the front regulation wall 50h and the rear regulation wall 51h around the one bending ring part 13h and the other bending ring part 14h.

The cords can be stored by forming one or two upper and lower spiral cords 15ha and 15hb around one bending wheel shaft 16h and the other bending wheel shaft 17h.
The winding means shown here is the same as that of the ninth embodiment, and as described above, it is possible to form the upper and lower two-layered spiral cords 15ha and 15hb. The winding means here can also form a single-layered spiral cord in which the left and right sides of the bent portion of the bending loop are alternately overlapped, as in the eighth embodiment.

In Figures 46 to 48, as in the ninth embodiment described above, the cord 6h is folded and the inside of one bending ring portion 13h is hung on one bending ring shaft 16h, and the two folded cord portions are held in the hand with one side on top and the other side on the bottom, stacked one on top of the other, and while maintaining this stacked state, as shown by arrow 27h, it is wound clockwise around the other bending ring shaft 17h with that hand to form the other bending ring portion 14h in two upper and lower stages, and then it is wound further around one bending ring shaft 16h on the left side to form the two upper and lower stages of spiral cords 15ha and 15hb.
In Fig. 46, the lower cord going rightward along the front side of one bending loop portion 13h does not turn clockwise around the other bending wheel shaft 17h, but goes immediately to the right-side right cord holding portion 5h, is fitted into the groove 8h of the right cord holding portion 5h, and is led out to the right as the right cord 6hb of the cord 6h. Meanwhile, the upper cord of the overlapped cord forms the other upper bending loop portion 14h around the other bending wheel shaft 17h, and then approaches the upper side of one bending loop portion 13h located below one bending wheel shaft 16h on the left side, but does not wind clockwise, goes immediately to the left-side left cord holding portion 4h, is fitted into the groove 7h of the left cord holding portion 4h, and is led out to the left as the left cord 6ha of the cord, showing the initial state of being wound in two layers, up and down.

Figures 49 and 50 show the state in which the cord 6h is fully wound in two spirals, one above the other, inside the cord storage device 1h. The state of the wound cord shown here is such that the upper spiral cord 15ha at the start of winding in Figure 46 faces the right cord holder 5h, is fitted into the groove 8h of the right cord holder 5h, and is led out to the right as the right side 6hb of the cord, and the lower spiral cord 15hb faces the left cord holder 4h, is fitted into the groove 7h of the left cord holder 4h, and is led out to the left as the left side 6ha of the left cord. In this way, when the inside of one bending loop part 13h in which the cord is folded is hung on one bending loop shaft 16h and wound between the other bending loop shaft 17h, it is arbitrary which side of the left or right cord holder the two folded cord parts will face, and this depends on the number of turns of the spiral.

In this embodiment, as in the ninth embodiment, one bending axle 16h and the other bending axle 17h are separated from each other in the left-right direction, so that a spiral cord that is long in the left-right direction is formed. The spiral cords 15ha and 15hb are restricted in their front-to-rear bulging by the front regulating wall 50h and the rear regulating wall 51h, so that an increase in the number of turns results in a spiral cord that is longer in the left-right direction.
In addition, since the front and rear sides of the spiral cord are covered by the front and rear regulating walls 50h, 51h, the cord storage device is advantageous for attaching to the middle portion of the cord.
The left and right cord holders 4h and 5h here are the same as those in the first embodiment. The left and right portions 6ha and 6hb of the cord 6h can be attached to and detached from the left and right cord holders 4h and 5h in the same manner as in the first embodiment.

51 to 59 show an eleventh embodiment of a cord storage device. This cord storage device 1i has a base plate 3i having a flat upper plate surface 2ia of a certain width, a front limiting wall 50ia that extends to the left and right at the front end of the upper plate surface 2ia at a height exceeding the height of the cord but not exceeding twice the height of the cord, a rear limiting wall 51ia that extends to the left and right at the rear end of the upper plate surface 2ia at a height that matches the height of the front limiting wall 50ia and is parallel to the front limiting wall 50ia, and a left cord holding portion 4i provided at the left end of the center position of the upper plate surface 2ia, and a flat outer upper plate surface 2ib that contacts the underside of the base plate 3ia and a front limiting wall 51a that extends to the left and right at the rear end of the upper plate surface 2ia. a front outer regulating wall 50ib on the upper plate surface 2ia at a left position between the left cord holding portion 4i and the right cord holding portion 5i; a rear outer regulating wall 51ib on the upper plate surface 2ia at a left position between the left cord holding portion 4i and the right cord holding portion 5i; one bending axle 16i which is provided on the outer upper plate surface 2ib at a right position between the left cord holding portion 4i and the right cord holding portion 5i and which projects upward to a height matching the height of the one bending axle 16i; a movement locking means which stops the sliding movement of the outer base plate 3ib relative to the base plate 3ia and removes it; and an outer hand winding means which winds the cord 6i in a spiral shape around the one bending axle 16i and the other bending axle 17i. The cord storage device is characterized by having a cord winding means of 25i, forming one bending ring part 13i around one bending ring shaft 16i between the left cord holding part 4i and the right cord holding part 5i, forming the other bending ring part 14i around the other bending ring shaft 17i, and forming a spiral cord of the desired number of stages (1 to 2 stages) inside the front regulation wall 50i, the front outer regulation wall 50ib, the rear regulation wall 51i, and the rear outer regulation wall 51ib around the one bending ring part 13i and the other bending ring part 14i to store the cord.

The winding means shown here is similar to that of the ninth and tenth embodiments, and upper and lower two-tiered spiral cords 15ia and 15ib are shown in Figures 51 to 54. Also, in the same manner as the eighth embodiment, a single-tiered spiral cord can be formed in which the left and right sides of the folded portion of the first bending ring part are alternately overlapped around the first bending ring shaft 16i and the second bending ring shaft 17i.
The left and right cord holders 4i and 5i shown here are the same as those in the first embodiment. The left and right portions 6ia and 6ib of the cord 6i can be attached to and detached from the left and right cord holders 4i and 5i in the same manner as in the first embodiment.

The movement locking means for stopping and releasing the left-right sliding movement of the outer substrate 3ib relative to the substrate 3ia is a front sawtooth groove 57ib formed so as to protrude inward at the upper end of the front outer regulation wall 50ib of the outer substrate 3ib, a rear sawtooth groove 58ib formed so as to protrude inward at the upper end of the rear outer regulation wall 51ib, a front hook tooth 53ia having a front push rod 55i that engages with the front sawtooth groove 57ib facing each other on the inside and protrudes outward at its upper part on a part of the right end side of the upper end of the front regulation wall 50ia of the substrate 3ia, and the substrate 3i The rear restricting wall 51ia of a has a rear hook 54ia on a part of the right end side of the upper end thereof, which has a rear push rod 56i that engages with the inside of the rear sawtooth groove 58ib and protrudes outward at its upper part, and the front push rod 55i and the rear push rod 56i are pushed inward with two fingers as shown by the arrows to disengage the front and rear hooks 53ia and 54ia, and the outer base plate 3ib is slid left and right a specified amount, and then the two fingers are released, thereby locking the left and right sliding movement of the outer base plate 3ib.

The winding means shown here involves folding the cord 6i and hanging the inside of the first bending loop portion 13i on the first bending wheel shaft 16i, holding the two folded cord portions in a vertically overlapping state with one side on top and the other side on the bottom, and winding it clockwise around the second bending wheel shaft 17i with the same hand as shown by the arrow 27i to form two upper and lower tiers of second bending loop portions 14i, and then winding it further around the first bending wheel shaft 16i on the left side to form two upper and lower tiers of spiral cords 15ia and 15ib.

In Figures 51 to 54, the lower cord going rightward in front of the first bending loop portion 13i does not turn clockwise around the second bending wheel shaft 17i, but goes immediately to the right-side right cord holding portion 5i, fits into the groove 8i of the right-side cord holding portion 5i, and is led out to the right as the right-side cord 6ib of the cord 6i. On the other hand, the upper cord of the overlapped cord forms the upper second bending loop portion 14i around the second bending wheel shaft 17i, and then approaches the upper side of the first bending loop portion 13i located below the first bending wheel shaft 16i on the left side, but does not wind clockwise, goes immediately to the left-side left cord holding portion 4i, fits into the groove 7i of the left-side cord holding portion 4i, and is led out to the left as the left-side cord 6ia of the cord 6i, showing the initial state in which it is wound in two layers, up and down.

Figures 55 and 56 show the state in which the cord 6i is fully wound into two spirals, one above the other. The state of the wound cord shown here is such that the upper spiral cord 15ia at the start of winding shown in Figure 51 faces the right cord holder 5i, fits into the groove 8i of the right cord holder 5i, and is led out to the right as the right side 6ib of the cord 6i, and the lower spiral cord 15ib faces the left cord holder 4i, fits into the groove 7i of the left cord holder 4i, and is led out to the left as the left side 6ia of the left cord 6i.

In this embodiment, the inner edge 60ia that protrudes inward from the upper end of the front restricting wall 50ia of the base plate 3ia and the inner edge 61ia that protrudes inward from the upper end of the rear restricting wall 51ia effectively prevent the upper spiral cord 15ia from protruding upward. A shaft through hole 52a is provided in the center of the right end of the base plate 3ia for the movement of the second bending wheel axle 17i provided on the upper plate surface 2ib of the outer base plate 3ib.

57 to 59 show the cord storage device 1i with the outer base plate 3ib fully extended to the right and locked by the movable locking means. The upper spiral cord 15ia faces the right cord holder 5i, is fitted into the groove 8i and led out to the right as the right side 6ib of the cord 6i, and the lower spiral cord 15ib faces the left cord holder 4i, is fitted into the groove 7i of the left cord holder 4i and led out to the left as the left side 6ia of the left cord 6i.
The upper spiral cord 15ia and the lower spiral cord 15ib have a fully extended distance between the first bending axle 16i and the second bending axle 17i, the portion between the first bending ring portion 13i and the second bending ring portion 14i is elongated in the left-right direction, and the spiral cords are restricted in their forward and backward bulging by the front and rear restricting walls 50ia and 51ia, forming oval spiral cords 15ia and 15ib that are elongated in the left-right direction. This improvement in the storage form allows for a further increase in the storage length.

The configuration and function diagram 60 of the cord storage device 1k shows the twelfth embodiment of the cord storage device. The cord storage device 1k has a similar configuration to the cord storage device 1j of the third embodiment in the cord holding portion and the winding body. The present invention is not limited to the positional relationship of the two cord holding portions that hold the cord at two points shown in the previous embodiments.
