Japanese Patent Laying-Open No. 2005-21297 (FIG. 1, pages 3-5)

  However, conventional electric storage shelves may damage the stored items or place a burden on the drive motor when the stored items are sandwiched between the front plate and the storage shelf when the storage shelf is raised. There is. In particular, when the operation switch is raised, the storage shelf is automatically raised when the operation switch is pressed once. Therefore, while holding one hand on the storage shelf, the other hand can accidentally press the lift switch to bring one hand forward. There is a possibility that so-called hand pinching between the plate and the storage shelf may occur. In addition, there is a high possibility that the user will keep an eye on the shelf while the storage shelf is rising, and there is a high possibility that the stored items will be sandwiched between the front plate and the storage shelf.

  In particular, when installing an electric storage shelf in a confined space such as a toilet, in many cases it is installed on the wall behind the toilet, so toilet paper etc. are stored in the storage shelf in such a posture as to lean out from the front of the toilet. To come. For this reason, storage is often performed with the hand placed on the storage shelf, and it is easy to put a hand or a finger between the front plate and the storage shelf.

  Here, when a stored item, a hand, or the like is sandwiched between the front plate and the storage shelf, if it is configured to electrically detect this, the number of parts will increase and the cost will increase. . Moreover, when it is set as the structure which opens and closes a door in response to the raising / lowering operation | movement of a cabinet like the raising / lowering cabinet with a door currently disclosed by patent document 1, the number of parts will increase and it will become high cost.

  The object of the present invention is to raise and lower the storage shelf with a simple configuration so as to allow a clearance between the front plate and the storage shelf to escape when a hand pinching occurs between the front plate and the storage shelf. Is to provide.

In order to solve the above-described problems, the lifting storage shelf according to the present invention is:
A storage shelf with an open front,
An elevating mechanism for elevating and lowering the storage shelf between a predetermined upper limit position and a lower limit position;
A front plate that is supported independently of the storage shelf and covers the front surface of the storage shelf at the upper limit position of the storage shelf;
The front plate is allowed to escape in a direction to widen a gap between the front plate and the front surface of the storage shelf when a hand is caught between the front surface and the front surface of the storage shelf. It is characterized by providing escape means.

  In a normal state, the storage shelf is raised to the upper limit position by the elevating mechanism, and the opening is covered with the front plate and blindfolded. Then, when a necessary item stored in the storage shelf is taken out or stored, when the user operates the lowering switch of the lifting mechanism, the storage shelf descends to the lower limit position and stops. The storage shelf opens at the lower limit position with the upper end of the opening positioned near the lower end of the front plate. And a user takes out a necessary thing from a storage shelf, or accommodates it.

  When the user operates the lift switch of the lifting mechanism to return the storage shelf to the original position, the storage shelf is raised. The lifting mechanism has a mechanism that automatically raises the storage shelf when the lift switch is pressed. Therefore, when lifting from the bottom of the storage shelf, the lift switch is accidentally turned on with the other hand while holding the storage shelf. When one hand is sandwiched between the front plate and the storage shelf by pressing, the front plate is released in a direction of widening the gap between the front plate and the front of the storage shelf. As a result, the user can easily pull out the sandwiched hand, fingertip, or the like. The same applies to the case where the storage shelf rises from a partially lowered state and a hand pinch occurs.

  In many cases, especially in confined spaces such as toilets, toilet paper and the like are stored in the storage shelf in such a posture as to lean out from the front of the toilet because it is installed on the wall behind the toilet. There is a case where storage is performed in a state of being hung, and it is easy to put a hand or a finger between the front plate and the storage shelf. Therefore, it is extremely effective in such an environment.

Moreover, the raising / lowering accommodation shelf of Claim 2 of this invention is the raising / lowering accommodation shelf of Claim 1,
The escape means is a hinge, and is characterized in that it connects an upper back surface of the front plate and a support member that protrudes from a wall on the back surface of the storage shelf and supports the front plate.

  By using the hinge as the escape means for the front plate, it is possible to effectively prevent hand pinching between the front plate and the storage shelf with a very simple configuration.

Moreover, the raising / lowering accommodation shelf of Claim 3 of this invention is the raising / lowering accommodation shelf of Claim 2,
The center of rotation of the hinge is disposed behind the front surface of the storage shelf.

  By placing the rotation center of the hinges behind the front of the storage shelf, the front plate can easily escape to the front side when a pinch occurs between the lower end of the front plate and the storage shelf. The person can easily pull out the hand or fingertip.

Moreover, the raising / lowering accommodation shelf of Claim 4 of this invention is the raising / lowering accommodation shelf of Claim 1 or Claim 2,
When the hand pinching occurs between the front plate and the support, the front plate is closed with a holding force that allows the escape means to widen the space between the storage shelf and the front plate. It is characterized by having a front plate closing means.

  The front plate is held at a position where the swing is suppressed by the front plate closing means and the storage shelf is always covered. This holding force is set to such an extent that the space between the storage shelf and the front plate can be widened when hand pinching occurs between the front plate and the storage shelf. Thereby, when hand pinching arises, a front board is made to escape to the near side, the space between a storage shelf and a front board is expanded, and it becomes possible for a user to cancel hand pinching easily.

  According to the present invention, when a holding pin is raised between the front plate when the storage shelf is raised, or when an object or the like is pinched, the front plate opens in the front direction and escapes. It is possible to easily remove the hand when pinching occurs, and to prevent the contents from being damaged.

  In addition, it becomes possible to widen the clearance between the front plate and the storage shelf when the hand shelf is raised while the storage shelf is rising with an extremely simple configuration, and the number of parts is small, It can be provided at low cost.

  Specifically, in a normal state, the storage shelf is raised to the upper limit position by the elevating mechanism, and the opening is covered with the front plate and blindfolded. Then, when a necessary item stored in the storage shelf is taken out or stored, when the user operates the lowering switch of the lifting mechanism, the storage shelf descends to the lower limit position and stops. The storage shelf opens at the lower limit position with the upper end of the opening positioned near the lower end of the front plate. And a user takes out a necessary thing from a storage shelf, or accommodates it.

  When the user operates the lift switch of the lifting mechanism to return the storage shelf to the original position, the storage shelf is raised. The lifting mechanism has a mechanism that automatically raises the storage shelf when the lift switch is pressed. Therefore, when lifting from the bottom of the storage shelf, the lift switch is accidentally turned on with the other hand while holding the storage shelf. When one hand is sandwiched between the front plate and the storage shelf by pressing, the front plate is released in a direction of widening the gap between the front plate and the front of the storage shelf. As a result, the user can easily pull out the sandwiched hand, fingertip, or the like.

  In many cases, especially in confined spaces such as toilets, toilet paper and the like are stored in the storage shelf in such a posture as to lean out from the front of the toilet because it is installed on the wall behind the toilet. There is a case where storage is performed in a state of being hung, and it is easy to put a hand or a finger between the front plate and the storage shelf. Therefore, it is extremely effective in such an environment.

  Hereinafter, an elevating storage shelf according to an embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, a toilet 5 is installed at a central position on the rear wall 2 side of the toilet 1, and an illumination lamp 6, an operation unit 7 for a local washing toilet seat, toilet paper 8, A hand-washer 9 and the like are arranged. In the toilet 1, the back wall is referred to as the rear wall 2 and the front wall is referred to as the front wall 4 while the user is seated on the toilet 5. An elevating storage shelf 11 is installed at an upper position of the rear wall 2. The front plate 12 of the storage shelf 11 is supported by left and right supports 13 provided to protrude forward from the rear wall 2. The storage shelf 14 is disposed between the left and right supports 13 so as to be movable up and down, and an opening portion that opens to the front surface 14d at the upper limit position shown in the figure is covered with the front plate 12 and is blindfolded.

  As shown in FIGS. 3 and 4, the support 13 includes an upper beam 15, a lower beam 16, a side plate 17, and a front plate 18. The upper beam 15 and the lower beam 16 are formed in a square pipe shape, projecting forward in parallel with a predetermined interval in the vertical direction and perpendicular to the rear wall 2, and the rear end portions of the rear beam and the back plate 19 are rearward. It is fixed to the upper part of the wall 2. And the side board 17 is being fixed to the both sides of the upper beam 15 and the lower beam 16, and the front board 18 is being fixed to the front end part. That is, the support 13 has a cantilever shape forming a board. In FIG. 3, the front plate 12 and the storage shelf 14 are seen through to facilitate understanding.

  Frames 21 and 22 are fixed in parallel to the back plate 19 at the upper end and substantially the center position in the lateral direction, and slide rails 23, guides 25 and 25, and a support frame 26 are placed at predetermined positions of these frames 21 and 22. It is arranged vertically and fixed in the vertical direction. The lower end portion of the support member 27 is fixed to the center of the upper surface of the upper plate 14 a of the storage shelf 14, and the support member 27 is fixed to the slider 24. The slider 24 can move vertically along the slide rail 23 in the vertical direction. A guide plate 28 is fixed at the center of the back surface of the back plate 14c of the storage shelf 14, and both side portions are guided by the guides 25 and 25 so as to be slidable in the vertical direction. Thereby, the storage shelf 14 can be moved up and down along the slide rails 23 and the guides 25 without shaking left and right.

  The elevating mechanism 31 includes a drive geared motor 32 fixed to one end portion of the frame 21, and a toothed pulley 33 whose rotating shafts are horizontally and rotatably supported at both upper and lower end portions of the support frame 26, 34 and a toothed belt (timing belt) 35 that is hung on the toothed pulleys 33 and 34. The output shaft of the geared motor 32 is connected to the rotating shaft of the upper toothed pulley 33. Further, the rear end portion of the upper plate 14 a of the storage shelf 14 shown in FIG. 3 is fixed to the toothed belt 35. As the geared motor 32 rotates, the upper toothed pulley 33 rotates, and accordingly, the toothed belt 35 moves up and down, and the storage rack 14 moves up and down.

  A constant load spring mechanism 41 is provided between the center position of the upper end of the back plate 19 and the upper plate 14 a of the storage shelf 14. The constant load spring mechanism 41 includes a drum 43 having a rotation shaft horizontally and rotatably supported on a bracket 42 provided at the center of the upper end of the back plate 19, and one end fixed to the drum 43. The other end is constituted by a constant load spring, for example, a conston spring 44, which is wound and whose other end is fixed to the central rear end of the upper surface 14a of the upper shelf 14a of the storage shelf 14. This constant load spring mechanism 41 is a spring having a characteristic that the torque to return to the original (torque returning to the drum 43) is constant and does not change depending on the stroke, and allows the storage rack 14 to be raised and lowered freely. As a result, the output of the geared motor 32 can be reduced, and the size and weight can be reduced.

  A dog 45 is attached to the upper end of the side portion of the slider 24, and position detectors such as limit switches 46 and 47 are attached to the upper and lower ends of the support frame 26 so as to be in contact with the dog 45. The limit switch 46 detects the upper limit position of the storage shelf 14, and the limit switch 47 detects the lower limit position of the storage shelf 14. Further, the lower end portion 28 a of the guide plate 28 extends downward from the lower surface 14 e of the lower plate 14 b of the storage shelf 14, and an operation unit 48 is attached thereto. The operation unit 48 is provided with a raising switch 49 for raising and lowering the storage shelf 14, a lowering switch 50 for lowering, a power switch 51, and the like. The ascending switch 49, the descending switch 50, the power switch 51, and the like are arranged facing forward, that is, facing the user.

  A controller 53 is disposed at a predetermined position on the back plate 19. The controller 53 controls the geared motor 32 by inputting signals from the limit switches 46 and 47 and the ascending switch 49, the descending switch 50, and the power switch 51 of the operation unit 48.

  On the other hand, as shown in FIGS. 3 and 4, escape means 55 are provided between the left and right sides of the back surface of the front plate 12 and the upper portions of the left and right supports 13. The escape means 55 has a front plate in a direction to widen a gap with the front surface 14d of the storage shelf 14 when hand clamping occurs with the front surface 14d of the storage shelf 14 when the storage shelf 14 is lifted from below. For example, the hinge 56 is used. The rotation axis (rotation center) 56a of the hinge 56 is positioned on the upper surface of the upper beam 15 of the support 13 at the rear of the front plate 18 by a predetermined distance d from the front surface of the front plate 18, that is, the front surface 14d of the storage shelf 14, and the rotation shaft 56a. The upper beam 15 is disposed slightly above the upper surface.

  The mounting portion 56b on one side of the hinge 56 is fixed perpendicularly to the upper beam 15 by a bracket 57, and the mounting portion 56c on the other side extends horizontally to the front side and is fixed to the front plate 12 by the bracket 58. It is fixed on the back of the. The front plate 12 hangs down by its own weight in parallel with the front plate 18 of the support 13 with a slight gap. The hinge 56 is disposed so that the rotation shaft 56a, that is, the center of rotation is located behind the front surface 14d of the storage shelf 14, so that the hinge 56 is located between the front surface 14d of the storage shelf 14 when the storage shelf 14 is lifted from below. Thus, the front plate 12 can be released in the direction of widening the gap between the front surface 14d of the storage shelf 14 when hand pinching occurs.

  The front plate 12 has an upper end portion 12a positioned substantially at the mounting height of the geared motor 32 and a lower end portion 12b positioned slightly below the lower surface of the storage shelf 14 when the storage shelf 14 is raised to the upper limit position. It is supposed to be. As a result, the front plate 12 is configured to conceal the accommodation shelf and to be rotated to a substantially horizontal position in the counterclockwise direction in the drawing, that is, in front of the user, as indicated by a two-dot chain line in FIG.

  The lower end 12b of the front plate 12 may have a square shape as shown in FIG. 4, or the edge on the back surface 12c side of the lower end 12b as shown in FIGS. 5 (a) to 5 (d). You may chamfer a part like 12d-12g. Thereby, it becomes possible to protect a user's hand effectively when pinching it. In this case, even if the rotating shaft 56a of the hinge 56 is not located behind the front surface 14d of the storage shelf 14, the front plate 12 is somewhat easily escaped, and there is an effect of preventing hand pinching to some extent.

  A front plate closing means 61 is provided between the left and right sides of the back surface of the front plate 12 and the lower portions of the front plates 18 of the left and right supports 13. The front plate closing means 61 is composed of a magnet 62 and a magnet catch 63 as shown in FIG. The magnet catch 63 is provided at the opening position of the lower beam 16 of the front plate 18 of the support 13, and the magnet 62 is fixed to the back surface 12 c of the front plate 12 so as to face the magnet catch. The front plate 12 is prevented from swinging by being held by the attractive force (holding force) between the magnet 62 and the magnet catch 63.

  The front plate closing means 61 normally holds the front plate 12 in a state where the magnet 62 is attracted to the magnet catch 63 and closes the front shelf 12 when the storage shelf 14 is raised. It is set so that the front plate 12 is closed with a holding force (magnetic force) that allows the clearance between the storage shelf 14 and the front plate 12 to be widened by the escape means 55 when hand pinching occurs.

  The operation will be described below. As shown in FIGS. 1 and 2, when the storage shelf 14 is in the upper limit position, the elevating storage shelf 11 is covered with a front plate 12 so that the front surface 14 d of the storage shelf 14 is covered. Since the lower end portion of the front plate 12 is located slightly below the lower surface 14e of the storage shelf 14, the storage shelf 14 is completely blinded, and the appearance is improved. In this state, the conston spring 44 of the constant load spring mechanism 41 is rewound onto the drum 43. When storing toilet articles such as toilet paper in the storage shelf 14, when the user presses the lowering switch 50, the geared motor 32 rotates to lower the storage shelf 14.

  Then, as the storage shelf 14 is lowered, the conston spring 44 of the constant load spring mechanism 41 is pulled out from the drum 43 against the spring force (torque). The conston spring 44 acts as a braking force that suppresses the lowering of the storage rack 14 when pulled out from the drum 43, prevents the storage rack 14 from dropping sharply, and when the geared motor 32 fails. It is possible to prevent the storage shelf 14 from dropping rapidly.

  When the storage shelf 14 is lowered to the lower limit position, the dog 45 comes into contact with the limit switch 47 and the limit switch 47 is activated. As a result, the geared motor 32 stops and the storage shelf 14 stops at the lower limit position shown in FIGS. The storage shelf 14 is provided with a plurality of shelves as shown in FIG. 7, and can store toilet articles such as toilet paper and cleaning articles.

  When the user presses the lift switch 49 after storing, for example, toilet paper in the storage shelf 14, the geared motor 32 rotates and the storage shelf 14 starts to rise. Since the raising / lowering mechanism 31 is configured to automatically raise the storage shelf 14 once the elevation switch 49 is pressed, the lifting switch 49 is erroneously pushed with the other hand while the other hand is placed on the storage shelf 14. There is a risk of so-called hand pinching that one hand is pinched between the front plate 12 and the storage shelf 14. In addition, there is a high possibility that the user will keep an eye while the storage shelf 14 is raised, and there is a high possibility that the storage object will be sandwiched between the front plate 12 and the storage shelf 14.

  In particular, when it is installed in a narrow place such as a toilet, as shown in FIGS. 1 and 2, since the lifting storage rack 11 is installed on the rear wall 2 behind the toilet 5, Toilet paper or the like comes to be stored in the storage shelf 14 in such a manner as to get on. For this reason, in many cases, the storage is performed with the hand placed on the storage shelf 14, and it is easy to put a hand or a finger between the front plate 12 and the storage shelf 14.

  Then, for example, while the user puts one hand on the storage shelf 14, the user accidentally presses the lift switch 49 with the other hand, and one hand is placed between the front plate 12 and the storage shelf 14 as shown in FIG. 8. When so-called hand pinching occurs, the escape means 55 causes the front plate 12 to escape as indicated by an arrow in a direction (front side) in which the gap between the front plate 12 and the front surface 14d of the storage shelf 14 is widened. As a result, the user can easily pull out the sandwiched hand, fingertip, or the like. When the user notices the hand pinching and presses the power switch 51, the geared motor 32 stops and the storage shelf 14 stops at that position. In this case, it is not always necessary to stop the storage shelf 14 by pressing the power switch 51.

  When the storage shelf 14 is raised, for example, when the toilet paper storage bag 70 stored in the storage shelf 14 falls down and is sandwiched between the front plate 12 and the storage shelf 14 as shown in FIG. The front plate 12 is released in a direction to widen the gap between the front plate 12 and the front surface 14d of the storage shelf 14. This prevents the toilet paper from being crushed or deformed. And if a user notices that the toilet paper storage bag 70 was pinched and pushed the power switch 51, the geared motor 32 will stop and the storage shelf 14 will stop in the said position. Thereby, the overload of the geared motor 32 is prevented. When the toilet paper storage bag 70 or the like is sandwiched and the storage shelf 14 is stopped, the user can open the front plate 12 to the near side and push it into the storage shelf 14 for storage. In addition, if it is impossible to fit into the storage shelf 14 at this stop position, the lowering switch 50 may be pushed to lower the storage shelf 14 to the lower limit position and stored again, and then the lifting switch 49 may be pressed again.

  When the storage shelf 14 rises to the upper limit position and the dog 45 activates the limit switch 46, the geared motor 32 stops, and the storage shelf 14 is stopped and held at the upper limit position. The conston spring 44 of the constant load spring mechanism 41 rewinds to the drum 43 as the storage shelf 14 rises, and the spring force (torque) at this time acts to pull up the storage shelf 14. That is, the conston spring 44 reduces the load when the storage shelf 14 is raised, and thereby the load on the geared motor 32 is reduced.

  10 to 12 show modified examples of the support structure for the front plate 12. In FIG. 10, the front surface 13a of the support 13 is formed in a taper shape slightly protruding forward from the upper end 13b to the lower end 13c, and the front plate 12 is shown in contact with the tapered front surface 13a. It is designed to be supported by a hinge that does not.

  Further, in FIG. 11, the attachment portion 64 a of the L-shaped bracket 64 that fixes the attachment portion 56 c of the hinge 56 to the back surface of the front plate 12 is fixed to the attachment portion 56 c of the hinge 56, and the attachment portion 64 b on the front plate 12 side is folded. The front plate 12 is formed in a substantially wedge shape that is inclined downwardly from the curved portion and toward the front side so that the front plate 12 slightly protrudes forward from the upper end to the lower end with respect to the vertical front surface 13a ′ of the support 13. It is intended to support.

  Further, FIG. 12 shows that the magnet 62 of the front plate closing means 6 is fixed to the back surface of the front plate 12 via a wedge-shaped attachment member 65 that protrudes slightly forward from the upper end toward the lower end. 12 is supported so as to slightly protrude forward from the upper end toward the lower end with respect to the front surface 13a 'of the support body 13.

  As shown in FIGS. 10 to 12, the front plate 12 is supported so as to slightly protrude forward from the upper end toward the lower end with respect to the front surfaces 13a and 13a ′ of the support body 13, whereby the lower end portion 12b of the front plate 12 is supported. 4 and 12 can be configured to be positioned further forward than the rotation shaft 56a of the hinge 56 shown in FIGS. 4 and 12, and when the storage shelf 14 is lifted from below, the front surface 14d of the storage shelf 14 The front plate 12 is made easier to escape in the direction of widening the gap with the front surface 14d of the storage shelf 14 when hand pinching occurs.

  Further, the support 13 may be extended forward (toward the user) to widen the gap between the front plate 12 and the front surface 14d of the storage shelf 14, or a part of the storage shelf 14, for example, use A gap may be provided between the front plate 12 and the front surface 14d of the storage shelf 14 by providing a notch at the center of the lower plate 14b that is easy for a person to handle.

  Further, a front plate opening suppression mechanism that suppresses the opening of the front plate 12 may be provided between the front plate 12 and the support 13. As this front plate opening suppression mechanism, for example, a front plate opening suppression mechanism 66 configured as shown in FIG. 14 is conceivable. In FIG. 13A, a chain 67 is attached between the back surface of the front plate 12 and the upper portion of the support 13 to prevent the front plate 12 from opening too much. In FIG. 13B, a coil spring 68 is attached between the back surface of the front plate 12 and the upper portion of the support 13 to urge the front plate 12 in the closing direction to prevent it from opening too much. is there. FIG. 13C shows a case where a link 69 is attached between the back surface of the front plate 12 and the upper portion of the support 13.

  A front plate that lifts and lowers the storage shelf whose front surface is opened between a predetermined upper limit position and a lower limit position by an elevating mechanism and covers the front surface of the storage shelf at the upper limit position of the storage shelf supported independently of the storage shelf When the hand is caught between the storage shelf and the front surface of the storage shelf when the storage shelf is lifted from below, the front plate is released in a direction to widen the clearance with the front surface of the storage shelf.

  Thereby, when raising from the lower side of the storage shelf, when the one hand is sandwiched between the front plate and the storage shelf by accidentally pushing the lift switch with the other hand while holding one hand on the storage shelf, With the escape means, the front plate can be released in the direction of widening the gap between the front surface of the storage shelf, and the user can easily pull out the sandwiched hand, fingertip, and the like.

  In many cases, especially in confined spaces such as toilets, the liftable storage shelves are installed on the wall behind the toilet bowl, so that toilet paper or the like is stored in the storage rack in such a posture as to lean out from the front of the toilet bowl. Therefore, the storage is often performed with the hand placed on the storage shelf, and it is easy to put a hand or a finger between the front plate and the storage shelf. Therefore, it is extremely effective in such an environment.

  Further, the escape means is a hinge, and connects the upper back surface of the front plate and the upper end of the cantilever-like support that protrudes from the rear wall of the storage shelf and supports the front plate, and the rotation center of the hinge is the center of the storage shelf. It is located behind the front. Thereby, when hand pinching arises between the lower end of a front board and a storage shelf, a front board becomes easy to escape to the near side, and it becomes possible for a user to pull out a hand and a fingertip easily.

  Further, the front plate closing means for closing the front plate with a holding force that allows the space between the storage shelf and the front plate to be widened by the release means when a pinch occurs between the front plate and the support. It has. The front plate is held at a position where the swing is suppressed by the front plate closing means and the storage shelf is always covered. And this holding force is made into the grade which can spread between a storage shelf and a front board when hand pinching arises between a front board and a storage shelf.
