Description

Technical Field

[0001] This specification relates to an elevator car operation panel and an elevator.

Background Art

[0002] Conventionally, an elevator car operation panel may be installed on the side wall of an elevator car. For example, a wheelchair - dedicated car operation panel of an elevator is installed on the side wall. The wheelchair - dedicated car operation panel of an elevator constitutes the design inside the elevator car, and there is a demand to prevent the appearance of screws for attachment on the design surface. In addition, there is a demand to make the wheelchair - dedicated car operation panel of an elevator flush with the wall surface of the car. When making the wheelchair - dedicated car operation panel of an elevator flush with the wall surface of the car, it is necessary to prevent unevenness between the wall surface and the surface of the car operation panel as much as possible. Conventionally, as a method for attaching a wheelchair - dedicated car operation panel of an elevator, a box is provided on the side wall of the car in a concave shape, and the wheelchair - dedicated car operation panel of the elevator is screwed to the box from the inner chamber side of the car. Then, the wheelchair - dedicated car operation panel of the elevator is pulled out to the inner chamber side, engaged with a hinge mechanism provided at the lower end of the box, and with the engaged part as a fulcrum, the upper part of the wheelchair - dedicated car operation panel of the elevator is rotated and pulled out, and the upper part of the box and the upper part of the wheelchair - dedicated car operation panel of the elevator are connected by a locking device to limit the rotation of the wheelchair - dedicated car operation panel of the elevator, and a technique for performing maintenance inside the wheelchair - dedicated car operation panel of the elevator is known. By the way, according to the conventional structure, since it is necessary to pull out the wheelchair - dedicated car operation panel of the elevator to the inner chamber side and engage it with the hinge mechanism provided at the lower end of the box, at least the lower end of the wheelchair - dedicated car operation panel of the elevator and the box need to be fixed by separate fixing means. For example, the conventional structure fixes it with decorative screws from the design surface on the inner chamber side of the car. Therefore, the wheelchair-accessible elevator control panel had to be fitted into the box and secured with decorative screws, which increased the workload and hindered the creation of simpler work procedures.

[0019] Furthermore, the side surface 94 is provided with a guide portion 22 that guides the faceplate 10 when attaching it to the car control panel box 9. In this embodiment, the guide portion 22 is a pin that protrudes from the side surface 94 toward the inside of the car control panel box 9. At least one guide portion 22 is provided on each of the pair of side surfaces 94. In this embodiment, two guide portions 22 are provided on each of the side surfaces 94. In this embodiment, a crimp nut, stud bolt, weld bolt, or self-clinching stud may be used as the pin for the guide portion 22.

[0020] The bottom surface 91 is provided with a locking portion 21 that locks onto the upper part 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] Figure 4(a) is an enlarged front view of part A, which is an enlarged view of the locking part 21 in Figure 3, and Figure 4(b) is an enlarged left side view of part A. In this embodiment, the locking part 21 is composed of a latch mechanism. The locking part 21 has a substantially L-shaped base part 19. One side of the base part 19 constitutes a base fixing part 191, and the other side constitutes a movable member fixing part 192. The base fixing part 191 is provided with a hole 193 for fixing to the bottom surface 91. The hole 193 is a hole made in the base fixing part 191, and the tip side of the base fixing part 191 is a semicircle, opening up to the connection part with the movable member fixing part 192. The fastened member 27 protruding from the bottom surface 91 is inserted through the hole 193 and fixed with a fastening member 26. In this embodiment, two holes 193 are provided, but three or more may be provided. Furthermore, the fastened member 27 may be a stud bolt, weld bolt, or self-clinching stud, or it may be a bolt that screws into the fastening member 26.

The movable member 18 is bent in a roughly L-shape, and the fastening member 24 is screwed into a tapped hole provided in the base end 181, which is one side of the movable member 18, and fastened to the other side of the flat hinge 23. The other side of the movable member 18, the bent portion 182, extends downward in the vertical direction D3 from the second lateral end of the base end 181. The bent portion 182 functions as a locking member of the latch mechanism and is displaced between a locked position in which the hook 31, which will be described later as a locked member, is locked, and an open position in which the elastic lock is released against the elastic force of the elastic member 231. The displacement of the bent portion 182 from the locked position to the open position is achieved by the rotation of the bent portion 182 counterclockwise in the plane of Figure 4(a) around the axis of the flat hinge 23.

[0024] Figure 5 is a plan view of the faceplate 10 with internal components omitted. The faceplate 10 has an upper rib 30 at the upper end of its back surface and lateral ribs 36 at both ends of its back surface. As shown in Figure 9, the lateral ribs 36 are provided with notches that form guided portions 35 which are guided by guide portions 22 provided on the side surface 94 of the cage control panel box 9. In this embodiment, each pair of lateral ribs 36 is provided with two guided portions 35 corresponding to the guide portions 22.

[0025] As shown in Figure 5, the upper rib 30 is provided with a locking portion 29 at a position corresponding to the locking portion 21, which is locked to a locking portion 21 provided on the bottom surface 91 of the cage control panel box 9. Figure 6 is an enlarged plan view of section B, which is an enlarged view of the locking portion 29 in Figure 5. In this embodiment, the locking portion 29 is composed of a hook 31 that is locked to the locking portion 21. The hook 31 is formed by providing a notch 38 in a part of the upper rib 30, and making the upper end of one of the upper ribs 30 facing the notch 38 protrude, forming a locking surface 311 that is parallel to the face plate 10 which is locked to the locking surface 1821 of the bent portion 182 shown in Figure 5(b). The hook 31 has an inclined surface 312 that slopes away from the locking surface 311 as it moves away from the notch 38 from the tip on the notch 38 side.

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

[0027] Figure 7 is a bottom view of the faceplate 10 with internal components omitted. The faceplate 10 has a lower rib 33 at the lower end of its back surface. As shown in Figure 7, the lower rib 33 has an engaged portion 32 that engages with an engaging portion 20 provided on the lower surface 92 of the car control panel box 9, and is provided at a position corresponding to the engaging portion 20. Figure 8 is an enlarged bottom view of section C, which shows the engaged portion 32 of Figure 7. In this embodiment, the engaged portion 32 is composed of a hole 34 that engages with the engaging portion 20. The hole 34 is a hole drilled in the lower rib 33, and opens to the base end of the lower rib 33 with the tip side of the lower rib 33 forming a semicircle. At least one engaged portion 32 is provided. In this embodiment, three engaged portions 32 are provided to match the engaging portion 20.

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

[0029] First, the pin, which is the engaging portion 20 provided on the lower surface 92 of the car control panel box 9, is inserted through the hole 34, which is the engaged portion 32 provided on the lower rib 33 of the faceplate 10, and the lower rib 33 of the faceplate 10 is rested on the lower surface 92 of the car control panel box 9.

[0030] Next, the faceplate 10 is rotated toward the car control panel box 9, using the engaging portion 20 and the engaged portion 32 as pivot points. At this time, the guided portion 35 provided on the lateral rib 36 of the faceplate 10 is guided along the guide portion 22 provided on the side surface 94 of the car control panel box 9.

[0031] As the tip of the faceplate 10 approaches the car control panel box 9, the inclined portion 312 on the hook 31 of the locking 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 control panel box 9. When the faceplate 10 is further rotated and pushed toward the car control 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 in the plane of Figure 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] Subsequently, the faceplate 10 is rotated further and pushed toward the car control panel box 9. When the faceplate 10 is aligned with the vertical direction D3, the bent portion 182, which was pushed aside by the inclined portion 312, returns to its locked position due to the elastic force of the elastic member 231. The locked surface 311 of the locked portion 29 is then locked to the locked surface 1821 of the bent portion 182, and the faceplate 10 is fixed to the car control panel box 9.

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

[0034] In this embodiment, the faceplate 10 is fixed substantially flush with the side wall 6, and a gap Y is provided between the upper edge of the faceplate 10 and the side wall 6. For example, in Figure 10(a), the maintenance worker performing the inspection inserts a thin metal or resin jig 39, such as a metal ruler, into the shaded area X of the gap Y. Then, the jig 39 is slid to the right in the plane of the paper along the shaded area X, bringing it into contact with the bent portion 182.

[0035] When the jig is slid further from the position where it is in contact with the bent portion 182, the movable member 18 (bent portion 182) moves counterclockwise in the plane of 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] Next, the jig 39 is used to push the faceplate 10 forward, and the end of the pushed-out faceplate 10 is grasped and the faceplate 10 is removed from the car control panel box 9.

[0037] [1] Based on the above, the elevator car control panel 2 is as in this embodiment. The elevator car control panel box 9 is located on the wall 6 inside the elevator car 5, The faceplate 10 attached to the inside of the elevator car 5 of the car control panel box 9 and An elevator car control panel 2 having, The faceplate 10 has an engaging portion 32 provided at the lower end of the back side for fixing to the car control panel box 9 by rotating the upper end with the lower end of the faceplate 10 as a pivot point, and a locking portion 29 at the upper end of the back side for locking with the car control panel box 9. The car control panel box 9 has an engaging portion 20 on the inside lower side that engages with the engaged portion 32, and locking portions 21 and 121 on the inside upper side for locking the locked portions 29 and 129. This configuration is preferable.

[0038] With this configuration, when viewed from inside the elevator car 5, the locking portions 29, 129 on the back surface of the faceplate 10 and the locking portions 21, 121 of the car control panel box 9 are locked together at a position where the faceplate 10 overlaps with the faceplate 10. Therefore, the faceplate 10 can be fixed to the car control panel box 9 without having to provide 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 an elevator car control panel 2 with a design in which screws are not exposed on the surface of the faceplate 10.

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

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

[0042] [3] The elevator car control panel 2 of the elevator [1] or [2] described above is The locking portion 29 is a hook 31 that protrudes horizontally from the upper part of the back surface of the faceplate 10. The locking portion 21 may be a latch 21 provided on the upper part of the bottom surface 91 of the cage control panel box 9, into which the hook 31 is locked.

[0043] With this configuration, the upper end of the faceplate 10 can be fixed to the elevator car control 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 control panel box 9. This makes it possible to provide an elevator car control panel 2 in which the faceplate 10 can be easily attached and detached.

[0044] [4] The elevator car control panel 2 in the above [3] is The latch 21 comprises a base portion 19 fixed to the bottom surface 91 of the cage control panel box 9, and a movable member 18 whose one end is rotatably connected to the base portion 19 via a flat hinge 23. The other end of the movable member 18 forms a bent portion 182 that bends in a direction perpendicular to the upper edge of the face plate 10. The elastic member 231 may be used to bias the bent portion 182 so that it remains aligned in a direction perpendicular to the upper edge of the faceplate 10.

[0045] With this configuration, the faceplate 10 can be attached to the elevator car control panel box 9 simply by pushing the faceplate 10 into the car control panel box 9, at which point the hook 31 is locked in place by the latch 21. This makes it possible to provide an elevator car control panel 2 that can be easily attached and detached.

[0046] [5] Furthermore, elevator 1 may be equipped with the elevator car control panel 2 described in [4] above.

[0047] With this configuration, the faceplate 10 can be secured by the latch 21 simply by pushing the faceplate 10 into the car control panel box 9. This makes it possible to provide an elevator 1 equipped with an elevator car control panel 2 that can be easily attached and detached.

[0048] It should be noted that the elevator car control panel 2 and elevator 1 are not limited to the configuration of the embodiment described above, nor are they limited to the effects described above. Furthermore, it goes without saying that the elevator car control panel 2 and elevator 1 can be modified in various ways without departing from the spirit of the present invention. For example, one or more of the configurations and methods described below may be arbitrarily selected and adopted in the configurations and methods of the embodiment described above.

[0049] (A) Although the elevator car control panel 2 according to the above embodiment was described as a wheelchair-accessible car control panel mounted on the side wall 6, it is not limited to this configuration.
