The opening can be maintained without closing the opening.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an open frame of a bag, and more particularly, to an opening of a bag made of a flexible material when the opening is opened, the opening is held firmly to facilitate removal of an article.

[0002]

[Prior art]

 In general, bags have various different design structures depending on the purpose of use so that articles can be stored and conveniently carried. For example, bags used by conventional carpentry and water / electricity workers to store tools are relatively simple in construction, made of duck cloth and have an upper end opening for taking in and out of articles. There is a soft bag with a flexible section to make it easier to insert and remove tools.

[0003] In addition, when carrying, a cylindrical hole through which a rope is passed is formed along the periphery of the upper end opening by sewing, so that the upper end opening is closed to facilitate carrying, and the rope is pulled. In some cases, the cloth around the upper edge of the opening is tightened, and the opening is folded and wrinkled. Even with such a sotobag, the tool cannot be fixed in and out because the opening cannot be fixed with the opening widened.

In view of the inconvenience of using the soft bag as described above, the bag 2 proposed by the present inventor and shown in FIG. 6 allows articles and tools to be put in and out of the opening 20 at the upper end thereof. The upper side pocket 21 is formed by sewing on the outer peripheral side surface on the shorter side of the rim, and a relatively small tool is accommodated in the side pocket 21. Also, a pair of hand-held handles 22 are sewn to the outer peripheral side surface on the longitudinal side.

A closing means 23 such as a zipper is fixed along the upper end edge of the opening 20 so that the opening 20 can be closed by the closing means such as the zipper. In addition, a frame member 3 composed of a symmetrically formed two bow-shaped frame 31 and two pivotal connection ears 32 is installed inside the upper end edge of the opening 20 so that the two bow-shaped frames 31 are opened when the opening 20 is opened. When opened in the state shown in the figure, the opening 20 is stretched and held at a predetermined size, so that articles can be easily taken in and out.

When the opening 20 is closed, as shown in FIG. 7, when the two arched frames 31 are pulled relative to each other with the two pivotal seats 32 as axes, the two arched frames 31 are brought close to each other. Thus, the opening 20 is closed, and the opening 20 is sealed by further operating the closing means 23.

[0007]

[Problems to be solved by the invention]

 The bag 2 uses the frame member 3 so that when the two arched frames 31 are unfolded, the opening 20 is stretched and fixed so that the tool can be easily inserted and removed, but this is not practically ideal. There's a problem. That is, although the two arched frames 31 can be expanded and stretched to hold the opening 20, when the tool or hand touches the pivotal ear 32 or the arched frame 31 when inserting or removing a tool, the pivotal ear 32 is turned downward. As a result, the two bow-shaped frames 31 may move together and close to each other to close the opening 20 in some cases. Further, since there is no latching effect on the pivotal connection between the pivotal connection ear 32 and the bow 31, when the bag 2 is moved with the opening 20 opened, the opening 20 is automatically closed automatically. And may cause inconvenience in use.

[0008] The present invention has been made in view of the above-described circumstances, and the opening of the bag, which is firmly held, is closed by contact with a hand or an article to be taken in or out, or by movement of the bag. The goal is to prevent them from being lost.

[0009]

[Means for Solving the Problems]

 In order to solve the above-mentioned problem, the present invention is an open frame of a bag which is provided on an inner surface near an upper edge of an upward opening of a bag, the frame including both arcuate frames and a pivoting seat for connecting them. The two arched frames have a configuration in which both ends of each arched frame are bent at substantially right angles in the same direction, and flat portions are formed at respective protruding ends. The flat portions at the protruding ends of the two arc-shaped frames are pivoted to form fitting holes opposed to each other at a position above the pivoted portion of the both side plates, while the inner side plates are bent inward at substantially right angles. A pivotal seat formed by extending a stretched plate and punching out a locking hole at the end of the stretched plate and projecting a folded plate piece downward from the bottom of the plate, and is slidable on the upper surface of the stretched plate. Fitting plates provided on both sides of its outer end when it is moved in the direction of the pivot plate. A sliding seat formed by inserting pivotal ears on both sides of an inner end opposite to the fitting plate while being inserted into fitting holes provided in the both side plates; A pivotal ear having a hole is formed, and the pivotal pin is inserted into the pivotal contact hole and the pivotal contact hole formed in both pivotal ears of the sliding seat. The sliding plate cannot be disengaged from the pivoting seat, and when the locking column protruding from the bottom of the base plate is inserted into the fitting hole of the sliding seat into the fitting hole of the pivoting seat, the extension plate is engaged. And a retaining seat that fits into the stop hole.

[0010] In the back opening frame of the present invention, when the two arc-shaped frames are deployed outward and right and left to stretch the opening of the bag, a force is applied to the end of the fastening seat to slide the fastening seat. After the seat is shifted to the pivot seat, the insertion plates on both sides of the sliding seat are inserted into the corresponding holes on the left and right sides of the corresponding side plates. When the locking pillar on the bottom is engaged in the locking hole at the end of the extension plate, the retaining seat and the sliding seat cannot move. Therefore, by holding the pivoting retaining seat in such a state, the two arched frames cannot be rotated due to the obstruction of the insertion plate, and when the opening of the back is in the open state, the external force is applied to the pivoting retaining seat and the bow. Even if it is added to the frame, the opening of the bag is not closed and the open state can be maintained.

The pivot seat is provided with an abutting edge between both edges of the both side plates, and when the two arc-shaped frames are developed, the flat portions abut against the abutting edge so that the abutting edges contact the abutting edge. It is preferable that both the arched frames are positioned (claim 2). With such a configuration, when both the arched frames are deployed, the deployed state can be more stably maintained.

It is preferable that the fitting hole of the pivot seat has a bent long hole shape, and that the cross-sectional shape of the fitting plate of the sliding seat has a bent shape corresponding to the fitting hole. Item 3). With such a configuration, the end pieces of the insertion plate are pressed against the arched frame, and the deployed state of both the arched frames is more stably maintained.

[0013]

[Embodiment of the invention]

 Hereinafter, an embodiment of the present invention will be described. The present invention is not limited to this embodiment. FIGS. 1 to 5 show an embodiment of the present invention, in which an open frame 100 of a bag is assembled by both arcuate frames 4 and two pivoting retaining seats 5. The open frame 100 of the bag is conventionally provided around an inner portion near the upper edge of a soft bag made of, for example, a flexible material. The configuration of the other parts of the soft bag, that is, the side pockets on the outer surface of the bag, the handle for the hand, the closing means such as the zipper fixed to the periphery of the opening, etc. are the same as in the above-mentioned conventional technology, and the description is omitted. The detailed configuration of the open frame, its functions and effects will be described in detail.

Each arc-shaped frame 4 has a substantially U-shape whose both ends are bent at substantially right angles in the same direction. Both protruding ends are formed in a flat portion 41, and a perforation 411 is formed in each flat portion 41. Has formed.

As shown in FIG. 2, the pivot contact seat 5 is pivotally mounted on a pivot seat 51, a slide seat 52 provided inside the pivot contact seat 51, and an inwardly protruding end of the slide seat 52. The pivot seat 51 includes a pair of side plates 511 extending upward and parallel to each other so as to face each other and provided with a contact edge 510 at a base side edge between the edge and the end green. A bent hole-shaped fitting hole 513 formed on both upper sides of a pair of both side plates 511, a circular hole formed slightly below the fitting hole 513, a pivot hole 512, and an inner side plate 511. An extension plate 514 extending inward at a substantially right angle from 511 at a position from a substantially middle portion in the longitudinal direction, a locking hole 515 formed by punching at a protruding end of the extension plate 514, and a stretching plate 514 formed by punching. And a folded plate piece 516 protruding downward from the bottom surface of the.

As shown in FIGS. 3 and 4, the connection between the pivotal seat 51 and the arched frame 4 is performed by inserting the flat portion 41 of the arched frame 4 between the side plates 511 and piercing the flat portion 41. The rivet 50 is pivotally inserted when the 411 corresponds to the two pivot contact holes 512 on the same side, whereby the bow-shaped frame 4 rotates about the pivotal attachment point of the rivet 50 as an axis. When the bow frame 4 is expanded, the flat portion 41 is brought into contact with the contact edge 510 of the pivot seat 51 so as to be positioned.

The sliding seat 52 is slidably mounted on the upper surface of the extension plate 514 of the pivotal seat 51, and the insertion plates 521 project from the outer ends on both sides thereof, respectively. The cross section corresponds to the shape of the fitting hole 513 of the side plate 511 of the pivoting seat 51, and when the sliding seat 52 moves toward the pivoting seat 51, the two insertion plates 521 are fitted into the two pivoting seats 51. It is adapted to be inserted into the hole 513 (FIG. 5). Further, on both sides of the opposite end of the sliding seat 52 from the insertion plate 521, a pivot contact ear 522 which is bent downward and has a pivot mounting hole 523 is provided.

The retaining seat 53 has a locking column 531 protruding at a substantially middle position on the bottom surface of the substrate portion 53 A, and the locking column 531 can be engaged with the locking hole 515 at the end of the extension plate 514. I am doing it. Further, a pivotal connection ear 532 in which a pivotal attachment hole 533 is formed at each outer end on both sides of the substrate portion 53 is extended downward, and both left and right pivotal ears 532 are disposed outside the both pivotal connection ears 522 of the sliding seat 52. , And the pivot pins 534 are inserted into the respective pivot attachment holes 533 and 523 to pivotally contact each other.

When the sliding seat 52 and the retaining seat 53 are installed on the pivotal seat 51, as shown in FIGS. 2 and 3, the sliding seat 52 is placed on the extension plate 514 and moved in the direction of the side plate 511. After the pivot hole 523 of the pivoting ear 522 of the sliding seat 52 is positioned closer to the side plate 511 than the folded plate piece 516, the pivoting ear 532 of the retaining seat 53 is connected to the pivoting ear 522 of the sliding seat 52. Positioned on the outside, the pivot pins 534 are pivotally inserted into the respective pivot holes 533, 523 and positioned. As a result, the pivoting pin 534 is prevented from moving in a direction far away from the pivotal seat 51 by the blocking action of the folded plate piece 516, and the sliding seat 52 and the retaining seat 53 integrally pivoted are prevented from falling off. Preventing. FIG. 3 shows a state in which when the sliding seat 52 and the retaining seat 53 move far away from the pivotal seat 51, the pivot pin 534 is restrained by the folded plate piece 516 and does not fall off.

On the other hand, when the sliding seat 52 is moved in a direction away from the pivotal seat 51 so that the insertion plates 521 are not inserted into both the insertion holes 513 of the both side plates 511, the bow-shaped frame 4 is moved to its pivot position. It is possible to turn the rivet 50 at the set location in an upright state with the rivet 50 as an axis (FIG. 3). As a result, the opening of the bag due to the close proximity of the two arched frames 4 is closed. On the other hand, when shortening the entire length of the pivoting retaining seat 5, as shown in FIG. 4, the retaining seat 53 is rotated toward the bottom surface of the extension plate 514, and the retention seat 53 is attached to the bottom surface of the extension plate 514. If they are brought together, the total length of the pivoting seat 5 can be reduced.

With the above configuration, when the both arched frames 4 are deployed outward and the opening of the soft bag is stretched, a force is applied to the end of the retaining seat 53 to pivotally connect the retaining seat 53 and the sliding seat 52. When the seat is shifted toward the seat 51, the insertion plates 521 on both sides of the sliding seat 52 can be inserted into both the insertion holes 513 of the corresponding both side plates 51, and then the fastening seat 53 is released. When the retaining seat 53 is rotated downward, and the retaining column 531 on the bottom surface of the retaining seat 53 is engaged in the retaining hole 515 at the end of the extension plate 514, the state shown in FIG. The sliding seat 52 cannot move completely. Therefore, when the pivotal anchoring seat 5 is fixed in such a manner that both the insertion plates 521 of the sliding seat 52 are inserted into the insertion holes 513 and are engaged between the both side plates 511, the two arc-shaped frames 4 are fixed. When the insertion plate 521 is blocked, it cannot be rotated in the relative direction. Even if an external force is applied to the pivoting retaining seat 5 and the arc-shaped frame 4 due to the contact of the article or the hand when the article is taken in or out, the opening of the soft bag is opened. The part keeps its open state without closing.

As described above, when the open frame 100 of the bag according to the present embodiment is used, as long as the retaining seat 53 and the sliding seat 52 maintain the above-described fitted orientation, the non-return orientation effect is provided to the entire opening frame. As a result, it is possible to prevent the opening from being unexpectedly closed when articles are taken in and out. Of course, frequent opening and closing of the bag does not close the opening.

In the open frame of the above-described embodiment, the pivot connection seat 5 is used on both sides, but this is used only on one side, and the other side is shown in FIG. A conventionally used pivot seat such as the pivot seat 32 shown may be used, and in this case also, a substantially similar effect of the above-described non-return localization to the opening frame can be provided.

[0024]

[Effect of the invention]

 As is clear from the above description, according to the open frame of the bag of the present invention, when the both arched frames are deployed in the left-right direction and are stretching the opening, the retaining seat and the sliding seat are pivoted. Push the seat in the direction of the seat so that the insertion plates on both sides of the sliding seat are inserted into the corresponding insertion holes on the left and right sides of the corresponding two sides, and the locking hole on the bottom surface of the locking seat is in the locking hole at the end of the extension plate. As a result, the retaining seat and the sliding seat cannot be moved, and at the same time, the two arched frames are restrained by the insertion plate and cannot be rotated relative to each other. Even if an article or hand touches the opening, the opening can be maintained without closing the opening. Therefore, it is possible to provide more convenient convenience in use as compared with the related art.
