Description

[Technical Field]

[0001] The present specification relates to an elevator car operating panel and an elevator. [Background technology]

[0002] Conventionally, elevator car operating panels have been installed on the side walls of elevator cars. For example, the wheelchair car control panel of an elevator is installed on a side wall. The elevator car control panel for wheelchairs constitutes the interior design of the elevator car, and there is a demand for the screws and other attachment parts to be hidden from view on the design surface. There is also a demand for elevator car control panels for wheelchair users to be flush with the car wall surface. When the wheelchair-dedicated elevator car control panel is to be flush with the wall surface of the car, it is necessary to minimize unevenness between the wall surface and the surface of the car control panel. Conventionally, one method of installing an elevator car control panel for wheelchairs has been to provide a recessed box in the side wall of the car and screw the elevator car control panel to the box from the interior of the car. A known technique for performing maintenance on the inside of an elevator wheelchair car control panel is to pull the elevator wheelchair car control panel into the interior, engage the elevator wheelchair car control panel with a hinge mechanism located at the bottom end of the box, rotate and pull out the top of the elevator wheelchair car control panel using the engaged part as a fulcrum, connect the top of the box and the top of the elevator wheelchair car control panel with a locking device to restrict the rotation of the elevator wheelchair car control panel. However, with the conventional structure, the wheelchair car control panel of the elevator must be pulled out into the interior and engaged with a hinge mechanism at the bottom of the box, so at least the bottom of the wheelchair car control panel and the box must be fixed with a separate fixing means. For example, in the conventional structure, the panel is fixed with decorative screws on the design surface on the interior side of the car. Therefore, the elevator's wheelchair car control panel had to be fitted into the box and secured with decorative screws, which increased the number of work steps and hindered the creation of simple work procedures.

[0020] The bottom surface 91 has a locking portion 21 that locks the upper portion of the faceplate 10. In this embodiment, the locking portion 21 is a latch provided at the upper center of the bottom surface 91.

[0021] 4(a) is an enlarged front view of part A of the locking portion 21 in FIG. 3, and FIG. 4(b) is an enlarged left side view of part A. In this embodiment, the locking portion 21 is configured as a latch mechanism. The locking portion 21 has a substantially L-shaped base portion 19. One side of the base portion 19 constitutes a base fixing portion 191, and the other side constitutes a movable member fixing portion 192. The base fixing portion 191 has a hole 193 for fixing to the bottom surface 91. The hole 193 is a hole formed in the base fixing portion 191, and has a semicircular tip end that opens to the connection portion with the movable member fixing portion 192. A fastened member 27 protruding from the bottom surface 91 is inserted through the hole 193 and fixed with a fastening member 26. Note that although two holes 193 are provided in this embodiment, three or more holes 193 may be provided. Furthermore, the fastened member 27 may be a stud bolt, a weld bolt, a self-clinching stud, or the like, or may be a bolt that screws into the fastening member 26 .

[0022] One piece of the flat hinge 23, which is biased by an elastic force downward in the up-down direction D3 by the elastic member 231, is fixed by the fastening member 24 to the upper side of the movable member fixing part 192 in the up-down direction D3 with a spacer 25 sandwiched between them.

In this embodiment, the latched portion 29 is formed by a hook 31 that latches onto the latching portion 21. The hook 31 is formed by forming a notch 38 in a part of the upper rib 30, and by protruding the upper end portion of one of the upper ribs 30 that faces the notch 38, thereby forming a latched surface 311 that is parallel to the face plate 10 and latches onto the latching surface 1821 of the bent portion 182 shown in FIG. 5(b). The hook 31 has an inclined surface 312 that slopes away from the latched surface 311 as it extends from the tip on the notch 38 side in a direction away from the notch 38.

[0026] Furthermore, by adjusting the mounting position of the locking part 21 in the vertical direction D3 on the car operating panel box 9 using the hole 193 of the locking part 21, the locking position of the locking part 21 and the locked part 29 can be set to the optimal position.

[0027] FIG. 7 is a bottom view of the face plate 10 with built-in components omitted. The face plate 10 has a lower rib 33 at the lower end of the back surface. As shown in FIG. 7, the lower rib 33 has an engaged portion 32 that engages with an engaging portion 20 provided on the underside 92 of the car operating panel box 9, provided at a position corresponding to the engaging portion 20. FIG. 8 is an enlarged bottom view of part C in FIG. 7, enlarging the engaged portion 32. In this embodiment, the engaged portion 32 is formed by a hole 34 that engages with the engaging portion 20. The hole 34 is a hole formed in the lower rib 33, and has a semicircular shape at the tip side of the lower rib 33, opening to the base end of the lower rib 33. At least one engaged portion 32 is provided. In this embodiment, three engaged portions 32 are provided in accordance with the engaging portions 20.

[0028] The configuration of the elevator car control panel 2 according to this embodiment has been described above. Next, a method for attaching the faceplate 10 to the car control panel box 9 in the elevator car control panel 2 according to this embodiment will be described using Figures 3 to 9. This is a procedure for removing the faceplate 10 from the car control panel box 9 for maintenance or the like, and then attaching the faceplate 10 to the car control panel box 9 again. Note that the following method is provided as an example to help understand how to attach the faceplate 10 to the car control panel box 9, and is not intended to limit the method for attaching the faceplate 10 to the car control panel box 9. <How to install the faceplate 10>

[0029] First, the pin, which is the engaging portion 20 provided on the underside 92 of the car operation panel box 9, is inserted into the hole 34, which is the engaged portion 32 provided in the lower rib 33 of the face plate 10, and the lower rib 33 of the face plate 10 is placed on the underside 92 of the car operation panel box 9.

[0030] Next, the face plate 10 is rotated toward the car operation panel box 9, with the engaging portion 20 and the engaged portion 32 as fulcrums. At this time, the guided portion 35 provided on the lateral rib 36 of the face plate 10 is guided along the guide portion 22 provided on the side surface 94 of the car operation panel box 9.

[0031] When the tip of the face plate 10 approaches the car operation panel box 9, the inclined portion 312 on the hook 31 of the locked portion 29 provided on the upper rib 30 comes into contact with the bent portion 182 of the movable member 18 that constitutes the locking portion 21 provided on the car operation panel box 9. When the face plate 10 is further rotated and pushed toward the car operation panel box 9, the inclined portion 312 pushes away the bent portion 182, and the movable member 18 moves upward in the vertical direction D3 (specifically, counterclockwise on the plane of FIG. 4(a)) against the elastic force of the elastic member 231 around the axis of the flat hinge 23, and is displaced from the locked position to the released position.

[0032] Thereafter, the face plate 10 is further rotated and pushed toward the car operation panel box 9 until the face plate 10 is aligned in the vertical direction D3. Then, the bent portion 182, which has been pushed aside by the inclined portion 312, returns to the engaging position due to the elastic force of the elastic member 231, and the engaging surface 311 of the engaging portion 29 is engaged with the engaging surface 1821 of the bent portion 182, and the face plate 10 is fixed to the car operation panel box 9.

[0033] The method for attaching the faceplate 10 according to this embodiment has been described above. Next, a method for removing the faceplate 10 from the car operating panel box 9 in the elevator car operating panel 2 according to this embodiment will be described using Figures 3 to 8 and 10. This is the procedure for removing the faceplate 10 from the car operating panel box 9 when removing the faceplate 10 from the car operating panel box 9 for maintenance or the like. Note that the following method is provided as an example to help understand how to remove the faceplate 10 from the car operating panel box 9, and does not limit the method for removing the faceplate 10 from the car operating panel box 9. <How to remove the faceplate 10>

[0034] In this embodiment, the face plate 10 is fixed to be approximately flush with the side wall 6, and a gap Y is provided between the upper edge of the face plate 10 and the side wall 6. For example, in FIG. 10(a), a maintenance worker performing an inspection inserts a thin metal or resin jig 39, such as a metal ruler, into the shaded portion X of the gap Y. Then, the jig 39 is slid to the right of the shaded portion X on the paper until it comes into contact with the bent portion 182.

[0035] When the jig is further slid from the state in which it abuts against the bent portion 182, the movable member 18 (bent portion 182) moves counterclockwise in the plane of the drawing in Figure 10(b) against the elastic force of the elastic member 231 around the axis of the flat hinge 23, and is displaced from the locked position to the released position. As a result, the hook 31 (locked portion 29) is released from the state in which it was locked by the locking portion 21.

[0036] Thereafter, the face plate 10 is pushed forward with the jig 39, and the end of the pushed-out face plate 10 is grasped with the hand to remove the face plate 10 from the car operation panel box 9.

[0037] [1] As described above, the elevator car operating panel 2, as in this embodiment, a car operation panel box 9 disposed on a wall surface 6 within the elevator car 5; a face plate 10 attached to the inside of the elevator car 5 of the car operation panel box 9; An elevator car operating panel 2 having The face plate 10 has an engaged portion 32 provided at a lower end on the back side for rotating an upper end of the face plate 10 around the lower end of the face plate 10 as a fulcrum to fix the face plate to the car operation panel box 9, and an engaged portion 29 at an upper end on the back side for engaging with the car operation panel box 9, The car operation panel box 9 has an engaging portion 20 on the inner lower side that engages with the engaged portion 32, and locking portions 21, 121 on the inner upper side for locking the locked portions 29, 129. This configuration is preferable.

[0038] According to this configuration, the engaging portions 29, 129 on the back surface of the faceplate 10 are engaged with the engaging portions 21, 121 of the car operation panel box 9 at a position that overlaps the faceplate 10 when viewed from inside the elevator car 5, so the faceplate 10 can be fixed to the car operation panel box 9 without the need to expose fastening members such as screws on the surface of the faceplate 10.

[0039] This makes it possible to provide an elevator car control panel 2 that can be easily attached and detached, and also to provide an elevator car control panel 2 that has a design in which the screws are not exposed on the surface of the face plate 10.

[0040] [2] The elevator car control panel 2 shown above in [1] is The car operation panel box 9 has a rectangular bottom surface 91 parallel to the wall surface 6 and a lower surface 92 protruding from at least the lower side of the bottom surface 91, The engaged portion 32 is at least one hole 34 provided in a lower rib 33 that projects horizontally along the lower edge of the rear surface of the face plate 10, The engaging portion 20 may be a pin 20 that protrudes vertically upward from the lower surface 92 of the car operating panel box 9 and is inserted into the hole 34 .

[0041] According to this configuration, the lower end of the faceplate 10 can be fixed to the car operating panel box 9 simply by engaging the pin 20 provided on the underside 92 of the car operating panel box 9 with at least one hole 34 provided in the lower rib 33 of the faceplate 10. This makes it possible to provide an elevator car operating panel 2 that can be easily attached and detached.

[0042] [3] The elevator car control panel 2 of the above [1] or [2] is The engaging portion 29 is a hook 31 provided on the upper part of the rear surface of the face plate 10 so as to protrude horizontally. The locking portion 21 may be a latch 21 that is provided on the upper part of the bottom surface 91 of the car operating panel box 9 and that locks the hook 31.

[0043] According to this configuration, the upper end of the faceplate 10 can be fixed to the car operating panel box 9 simply by engaging the hook 31 provided on the upper rib 30 of the faceplate 10 with the latch 21 provided on the bottom surface 91 of the car operating panel box 9. This makes it possible to provide an elevator car operating panel 2 in which the faceplate 10 can be easily attached and detached.

[0044] [4] The elevator car control panel 2 shown above in [3] is The latch 21 includes a base portion 19 fixed to the bottom surface 91 of the car operation panel box 9, a movable member 18 having one end rotatably connected to the base portion 19 via a flat hinge 23, and The other end of the movable member 18 forms a bent portion 182 that is bent in a direction perpendicular to the upper side of the face plate 10, The bent portion 182 may be biased by an elastic member 231 so as to maintain a state along a direction perpendicular to the upper side of the face plate 10 .

[0045] According to this configuration, simply by pushing the face plate 10 into the car operation panel box 9, the hook 31 is locked by the latch 21. This makes it possible to provide an elevator car operation panel 2 that can be easily attached and detached.

[0046] [5] The elevator 1 may also be equipped with the elevator car operating panel 2 described above in [4].

[0047] According to this configuration, the hook 31 of the face plate 10 is locked by the latch 21 simply by pushing the face plate 10 into the car operating panel box 9. This makes it possible to provide an elevator 1 equipped with an elevator car operating panel 2 that can be easily attached and detached.

[0048] The elevator car operating panel 2 and the elevator 1 are not limited to the configurations of the above-described embodiments, nor are they limited to the above-described functions and effects. Furthermore, the elevator car operating panel 2 and the elevator 1 can, of course, be modified in various ways without departing from the spirit of the present invention. For example, it is of course possible to arbitrarily select one or more of the configurations, methods, etc. of the various modified examples described below and adopt them in the configurations, methods, etc. of the above-described embodiments.

[0049] (A) The elevator car operating panel 2 according to the above embodiment has been described as a wheelchair-specific car operating panel attached to the side wall 6, but it is not limited to this configuration. For example, even if the elevator car operating panel 102 shown in Figure 1 is attached to the sleeve wall 4, it goes without saying that the same action and effect can be obtained.

[0050] (B) Furthermore, in the elevator car operating panel 2 according to the above embodiment, the elevator car operating panel 2 is configured to be approximately flush with the side wall 6, but this is not limited to such a configuration. For example, the elevator car operating panel 2 may protrude from the side wall 6, or may be recessed from the side wall 6. The point is that it is sufficient that, when viewed from inside the elevator car 5, there is a gap between the side wall 6 and the elevator car operating panel 2 into which the jig 39 can be inserted.

[0051] (C) Furthermore, in the elevator car operating panel 2 according to the above embodiment, the guide portion 22 is provided on the side surface 94 of the car operating panel box 9, and the guided portion 35 is provided on the lateral rib 36 of the face plate 10, and the face plate 10 is guided when attached to the car operating panel box 9, but this configuration is not limited to this. The car operating panel box 9 may not have the guide portion 22, and the face plate 10 may not have the guided portion 35.

[0052] <Second embodiment> (D) Furthermore, in the elevator car operating panel 2 according to the above embodiment, the locking portion 21 is a latch. Specifically, hooks 31 serving as locked portions 29 provided on the face plate 10 are locked to the locking portion 21 of the latch mechanism provided on the car operating panel box 9, and the face plate 10 is fixed to the car operating panel box 9. However, the elevator car operating panel 2 is not limited to this configuration.

[0053] For example, as shown in Fig. 11, a locking portion 121 provided on a car operating panel box 109 may be configured as a catch mechanism. Although not particularly limited, an example of such a configuration may be the configuration shown in Fig. 12.
