[0006] Patent Document 1: Japanese Utility Model Application Publication No. 58-41784 Summary of the Invention

[0007] The problem that the invention aims to solve

[0008] However, in conventional elevator car wall panels, the back panel 4 encloses the central space of the wall panel, but not the upper, lower, and side spaces. Therefore, there is a problem where external noise can easily be transmitted into the passenger car.

[0009] This invention was made to solve the problems described above.

[0010] Methods for solving problems

[0011] The elevator car wall of the present invention comprises: a surface panel fixed to the car room such that its surface side faces the inside of the car room and its back side faces the outside of the car room; a back panel mounted on the back side of the surface panel; and a clamping member that fixes the back panel to the surface panel. The surface panel has: an exterior design portion forming the inner surface of the car room; and an edge portion extending from the outer edge of the exterior design portion toward the outside of the car room. The clamping member is disposed inside the space enclosed by the exterior design portion and the edge portion and is fixed to the edge portion. The back panel and the exterior design portion are disposed off the ground. The back panel is fixed to the edge portion in a detachable manner by being clamped by the clamping member and enclosing the space.

[0012] Invention Effects

[0013] In the elevator car wall of the present invention, the back panel can be easily installed and removed from the back side of the surface panel. By installing the back panel on the surface panel, the space enclosed by the appearance design part of the surface panel and the surrounding edge can be sealed off, making it difficult for external noise from the car to be transmitted into the interior of the car.

Detailed Implementation

[0023] Hereinafter, a preferred embodiment of the elevator car wall of the present invention will be described with reference to the accompanying drawings.

[0024] Implementation Method 1

[0025] First, the elevator car wall in Embodiment 1 will be described using the accompanying drawings. Figure 1 This is a top view showing the hoistway, car room, and landing in Embodiment 1 and Embodiment 2. Figure 1 This is a top-down view taken from the middle section at the height of the car compartment. Figure 2 This is an overall view of the elevator car wall in Implementation Method 1. Figure 2 Showing the setting in Figure 1 The walls of the car compartment in section A. Figure 2 (a) is the top view. Figure 2 (b) is the rear view. Figure 3 This is a detailed view of the elevator car wall in Implementation Method 1. Figure 3 Show Figure 2 Part B. Figure 3 (a) is a top view. Figure 3 (b) is the rear view. Figure 3 (c) is the left view. Figure 4 This is a detailed view of the elevator car wall in Implementation Method 1. Figure 4 Show Figure 2 Section C. Figure 4 (a) is a top view. Figure 4 (b) is the rear view. Figure 4 (c) is the left-hand diagram.

[0026] In the attached diagram, label 1 is the hoistway, label 2 is the landing, label 3 is the landing entrance / exit, label 4 is the landing door, label 5 is the car room, label 6 is the car room entrance / exit, label 7 is the car room door, label 8 is the car room floor, and label 9 is the car room wall.

[0027] Shaft 1 connects multiple floors of the building. Landing station 2 is adjacent to shaft 1. Landing station 2 is located on multiple floors. Landing station 2 has landing entrances / exits 3. Landing entrances / exits 3 are opened and closed via landing doors 4.

[0028] The elevator car 5 moves up and down within the hoistway 1. The elevator car 5 moves between multiple floors. The elevator car 5 transports the elevator users from the departure floor to the destination floor.

[0029] The elevator car 5 is equipped with an entrance / exit 6. The entrance / exit 6 is opened and closed via a car door 7. When the elevator car 5 reaches the floor where landing 2 is located, the entrance / exit 6 is opposite to the landing entrance / exit 3. When the elevator car 5 reaches the floor where landing 2 is located, both landing door 4 and car door 7 are opened. Elevator users enter and exit the interior of the elevator car 5 from landing 2, which is adjacent to the hoistway 1, through landing entrance / exit 3 and car entrance / exit 6.

[0030] The elevator car 5 is provided with an elevator car floor 8. The elevator car floor 8 forms the floor surface of the elevator car 5. The elevator users take the elevator from the departure floor 2 onto the elevator car floor 8, and go up and down from the elevator car floor 8 to the destination floor 2.

[0031] The elevator car 5 is provided with a car car wall 9. The car car wall 9 surrounds the car car floor 8. The car car wall 9 extends upward from the car car floor 8. The elevator users are protected by the car car wall 9 from going from the interior of the car car 5 to the hoistway 1.

[0032] The car wall 9 includes a surface panel 10, a reinforcing member 11, a back panel 12, a clamping member 13, and screws 14. The car wall 9 is, for example, symmetrical from left to right. The vertical direction of the car wall 9 is, for example, the long side direction.

[0033] Here, the front, back, top, bottom, left, and right sides of the car wall 9 correspond to the front, back, top, bottom, left, and right sides of the car wall 9 when viewed from inside the car room 5. The surface side, back side, upper side, lower side, left side, and right side of the car wall 9 correspond to the surface side, back side, upper side, lower side, left side, and right side of the car wall 9 when viewed from inside the car room 5. The front-back direction, vertical direction, and horizontal direction of the car wall 9 correspond to the thickness direction, height direction, and width direction of the car wall 9 when it is installed in the car room 5.

[0034] The surface side of the surface panel 10 faces the inside of the car compartment 5. The back side of the surface panel 10 faces the outside of the car compartment 5. The surface panel 10 is a curved plate-shaped component. The surface panel 10 has an exterior design section 15 and an edge section 16.

[0035] The exterior design section 15 forms the inner surface of the car compartment 5. The exterior design section 15 extends in the left-right and up-down directions. The exterior design section 15 is, for example, flat. The exterior design section 15 is, for example, rectangular.

[0036] Edge 16 extends from exterior design section 15 toward the outer side of car compartment 5. Edge 16 extends from the outer edge of exterior design section 15 around its perimeter. Edge 16 extends from the outer edge of the upper, lower, left, and right sides of exterior design section 15. Edge 16 has a first edge 16a and a second edge 16b.

[0037] The first edge portion 16a extends from the outer edge of the exterior design portion 15. The first edge portion 16a extends from the exterior design portion 15 toward the outer side of the car compartment 5. The first edge portion 16a extends perpendicularly to the exterior design portion 15, for example. The first edge portion 16a extends along the outer edge of the exterior design portion 15. The first edge portion 16a is, for example, flat. The first edge portion 16a is, for example, rectangular. The upper first edge portion 16a faces the lower first edge portion 16a. The right first edge portion 16a faces the left first edge portion 16a.

[0038] The edge 16 of the surface panel 10 is fixed to the car compartment 5. The upper first edge 16a is, for example, engaged with a car compartment ceiling (not shown) provided in the car compartment 5 using screws. The lower first edge 16a is, for example, engaged with the car compartment floor 8 using screws. The right and left first edges 16a are, for example, engaged with adjacent car compartment walls 9 using screws.

[0039] The second edge portion 16b extends from the first edge portion 16a. The second edge portion 16b extends from the end of the first edge portion 16a on the side opposite to the appearance design portion 15. The second edge portion 16b is separate from the appearance design portion 15. The upper and lower second edge portions 16b extend towards each other. The right and left second edge portions 16b extend towards each other. The second edge portion 16b extends, for example, parallel to the appearance design portion 15. The second edge portion 16b is, for example, flat. The second edge portion 16b is, for example, rectangular.

[0040] Two adjacent second edges 16b abut against each other. For example, the ends of two adjacent second edges 16b overlap each other in the front-back direction. For example, the ends of two adjacent second edges 16b join together.

[0041] The second edge portion 16b has a groove 16c. The groove 16c extends toward the appearance design portion 15. The groove 16c is formed by recessing the end face of the second edge portion 16b. The groove 16c is provided, for example, at the upper end of the lower side of the second edge portion 16b. The groove 16c is recessed downwards, for example.

[0042] A reinforcing member 11 is disposed on the back side of the surface panel 10. The reinforcing member 11 is disposed inside a space 17 enclosed by the design section 15 and the surrounding edges 16. The space 17 is surrounded by the design section 15 and the upper, lower, left, and right edges 16. The reinforcing member 11 is, for example, mounted to the design section 15. The reinforcing member 11 is, for example, engaged with the design section 15. The reinforcing member 11 is, for example, bonded to the design section 15. The reinforcing member 11 is a curved plate-like member. The reinforcing member 11 has a side portion 11a.

[0043] Side portion 11a is separate from the appearance design portion 15. Side portion 11a extends, for example, parallel to the appearance design portion 15. Side portion 11a extends, for example, parallel to the second edge portion 16b. Side portion 11a is, for example, positioned at the center between the left edge portion 16 and the right edge portion 16. Side portion 11a extends, for example, between the upper edge portion 16 and the lower edge portion 16. Side portion 11a is, for example, flat. Side portion 11a is provided with a threaded hole 11b. The centerline of the threaded hole 11b is, for example, set perpendicular to the side of side portion 11a opposite to the appearance design portion 15.

[0044] The back panel 12 is mounted on the rear side of the surface panel 10. The back panel 12 forms the outer surface of the car compartment 5. The back panel 12 is separate from the exterior design section 15. The back panel 12 is a curved plate-shaped component. The back panel 12 is formed symmetrically, for example, in the left-right direction. The back panel 12 has a closing section 12a and a mounting section 12b.

[0045] The closing portion 12a extends between the upper, lower, left, and right edges 16. The closing portion 12a extends parallel to the appearance design portion 15, for example. The closing portion 12a is, for example, flat. The closing portion 12a is, for example, rectangular. The closing portion 12a abuts against the side portion 11a of the reinforcing member 11. The closing portion 12a overlaps, for example, the side of the side portion 11a of the reinforcing member 11 opposite to the appearance design portion 15. The closing portion 12a is provided with a hole 12c. The centerline of the threaded hole 11b of the reinforcing member 11 passes through the hole 12c.

[0046] Mounting portion 12b extends from closing portion 12a toward appearance design portion 15. Mounting portion 12b extends perpendicularly to closing portion 12a, for example. Mounting portion 12b extends from the end of closing portion 12a, for example. Mounting portion 12b is located inside space 17.

[0047] The clamping member 13 is disposed inside the space 17. The clamping member 13 has a fixing part 13a and a clamping part 13b.

[0048] The fixing part 13a is fixed to the edge part 16. The fixing part 13a is fixed to the second edge part 16b, for example, by a rivet.

[0049] The clamping part 13b is mounted on the fixing part 13a. The clamping part 13b is connected to the surface design part 15 side of the fixing part 13a. The clamping part 13b is fixed to the surface design part 15 side of the fixing part 13a, for example, by spot welding. A gap 13c is separated between the clamping part 13b and the fixing part 13a. The gap 13c opens toward the side opposite to the surface design part 15. The gap 13c opens toward the rear side of the car wall 9.

[0050] The fixing part 13a is, for example, a plate-shaped component formed by the first piece and the second piece, with the first piece fixed to the edge part 16 and the clamping part 13b fixed to the second piece, and a gap 13c separating the second piece and the clamping part 13b.

[0051] The mounting portion 12b of the back panel 12 is inserted into the space 17 from the rear side of the car wall 9. The mounting portion 12b of the back panel 12 is inserted from the rear side of the car wall 9 towards the exterior design portion 15. The mounting portion 12b of the back panel 12 is inserted into the space 17 in the front-rear direction of the car wall 9. The mounting portion 12b of the back panel 12 is inserted into the gap 13c. The mounting portion 12b of the back panel 12 is inserted into the gap 13c from the side opposite to the exterior design portion 15. The mounting portion 12b is clamped between the fixing portion 13a and the clamping portion 13b. The gap 13c is elastically expanded by the insertion of the mounting portion 12b. The clamping portion 13b presses the mounting portion 12b against the fixing portion 13a.

[0052] Screw 14 passes through hole 12c in back panel 12 and is screwed into threaded hole 11b in reinforcing member 11. Screw 14 secures back panel 12 to reinforcing member 11.

[0053] As described above, the back panel 12 encloses the space 17. The back panel 12 encloses the central, upper, lower, left, and right portions of the space 17. The back panel 12 divides the space 17 into the space of the hoistway 1, which is located outside the car wall 9. By mounting the back panel 12 to the surface panel 10, the space 17 is enclosed relative to the space of the hoistway 1, which is located outside the car wall 9.

[0054] Furthermore, the clamping member 13 secures the back panel 12 to the surface panel 10. The back panel 12 is secured to the edge 16 in a detachable manner by being clamped by the clamping member 13.

[0055] Furthermore, when mounting the back panel 12 onto the surface panel 10, the mounting portion 12b is inserted into the gap 13c while remaining engaged in the groove 16c. The back panel 12 is guided to move into the gap 13c by engaging with the groove 16c.

[0056] In the elevator car wall of Embodiment 1, there are: a surface panel 10, which is fixed to the car 5 with its surface side facing the inside of the car 5 and its back side facing the outside of the car 5; a back panel 12, which is installed on the back side of the surface panel 10; and a clamping member 13, which fixes the back panel 12 to the surface panel 10. The surface panel 10 has: an appearance design portion 15, which forms the inner surface of the car 5; and an edge portion 16, which extends from the outer edge of the appearance design portion 15 to the outside of the car 5. The clamping member 13 is disposed inside the space 17 enclosed by the appearance design portion 15 and the surrounding edge portion 16, and is fixed to the edge portion 16. The back panel 12 is disposed separately from the appearance design portion 15, and is fixed to the edge portion 16 in a detachable manner by being clamped by the clamping member 13, and encloses the space 17.

[0057] Therefore, the back panel 12 can be easily installed and removed from the back side of the surface panel 10. By installing the back panel 12 onto the surface panel 10, the space 17 enclosed by the appearance design section 15 of the surface panel 10 and the surrounding edge 16 can be sealed off, making it difficult for external noise from the car room 5 to be transmitted into the interior of the car room 5.

[0058] Furthermore, by removing the back panel 12 from the surface panel 10, it is possible to easily remove, for example, the screws that attach the surface panel 10 to the car compartment 5.

[0059] Furthermore, since the back panel 12 forming the outer surface of the car compartment 5 is separately mounted on the surface panel 10 from the exterior design section 15, it is possible to prevent external noise from the car compartment 5 from being transmitted into the interior of the car compartment 5.

[0060] Furthermore, since the back panel 12 is not pressed against the appearance design section 15, the appearance design section 15 does not flex, thus suppressing the reduction of appearance design.

[0061] In addition, the back panel 12 is fixed to the surface panel 10 in a detachable manner, so the base materials of the surface panel 10 and the back panel 12 are not fixed or joined to each other, making it difficult for external noise from the car to be transmitted into the interior of the car.

[0062] Furthermore, the back panel 12 is fixed to the surface panel 10 inside the space 17 of the surface panel 10 using a clamping member 13, thus making the back of the car wall 9 smooth and reducing the wind noise generated when the car 5 travels inside the hoistway 1.

[0063] Furthermore, the back panel 12 is inserted into the space 17, so even if the back panel 12 is lowered, it is supported by the surface panel 10, making it difficult to detach from the surface panel 10.

[0064] Furthermore, the surface panel 10 is fixed to the car compartment 5, while the back panel 12 is not fixed to the car compartment 5 but is fixedly mounted to the surface panel 10. Therefore, for example, when the car compartment wall 9 is pressed from the inside of the car compartment 5, the surface panel 10 functions as a support member, while the back panel 12 may not function as a support member. Thus, it is possible to suppress the increase in weight of the back panel 12.

[0065] Furthermore, by fixing the surface panel 10 to the car compartment 5 and then installing the back panel 12 onto the surface panel 10, the weight of the transported components can be reduced compared to fixing the back panel to the car compartment wall beforehand.

[0066] In the elevator car wall of Embodiment 1, the back panel 12 has a mounting portion 12b extending toward the appearance design portion 15. The clamping member 13 has a fixing portion 13a, which is fixed to the edge portion 16; and a clamping portion 13b, which is mounted on the fixing portion 13a with a gap 13c between it and the fixing portion 13a. The gap 13c is open toward the side opposite to the appearance design portion 15. The back panel 12 is clamped between the fixing portion 13a and the clamping portion 13b by inserting the mounting portion 12b into the gap 13c from the side opposite to the appearance design portion 15.

[0067] Therefore, when the back panel 12 is installed on the surface panel 10, the back panel 12 is moved from the back side of the car wall 9 toward the exterior design section 15. This eliminates the need for the back panel 12 to extend relative to the surface panel 10 in the up, down, left, and right directions, reducing the space required for movement. In particular, this is effective when the back panel 12 is installed on the surface panel 10 inside the hoistway 1 while the surface panel 10 is fixed to the car compartment 5.

[0068] Furthermore, when inserting the back panel 12 into the gap 13c, the back panel 12 is inserted in the direction of the side of the closed portion 12a of the back panel 12, so that the hand can fully contact the side of the closed portion 12a to insert the back panel 12 into the space 17, and the back panel 12 can be easily installed on the surface panel 10.

[0069] Furthermore, since the closing portion 12a and the mounting portion 12b of the back panel 12 extend in different directions, the rigidity of the back panel is increased and it is difficult to bend, making it easier to handle goods on the back panel 12.

[0070] In the elevator car wall of Embodiment 1, the edge 16 of the surface panel 10 has a groove 16c, and the back panel 12 is inserted into the gap 13c while maintaining its engagement with the groove 16c.

[0071] Thus, the back panel 12 is reliably clamped and fixed to the surface panel 10 by the clamping member 13, so that the back panel 12 can be easily installed on the surface panel 10.

[0072] Furthermore, in the elevator car wall of Embodiment 1, the clamping member 13 can also abut against the exterior design section 15.

[0073] In this case, the deflection of the exterior design section 15 caused by pressing it from inside the car compartment 5 is reduced, thus improving the user's sense of security.

[0074] Alternatively, in the elevator car wall of Embodiment 1, the clamping member 13 can also be fixed to the car 5 together with the edge 16 by screws.

[0075] In this case, by using screws to fix the edge 16 to the car chamber 5, the clamping member 13 can be firmly fixed to the edge 16, thereby reducing product costs.

[0076] Furthermore, in the elevator car wall of Embodiment 1, the back panel 12 can be divided. The back panel 12 can be divided vertically. The back panel 12 can also be divided horizontally. The divided back panels 12 are fixed to the reinforcing members 11, for example, by screws 14. If the divided back panels 12 are closed to each other by the reinforcing members 11, the divided back panels 12 may not need to abut against each other.

[0077] In this case, the back panel 12 becomes smaller and lighter, thus making it easier to handle goods on the back panel 12.

[0078] Implementation Method 2

[0079] Next, the elevator car walls in Embodiment 2 will be described using the accompanying drawings. Figure 5 This is an overall view of the elevator car wall in Implementation Method 2. Figure 5 Showing the setting in Figure 1 The walls of the car compartment in section A. Figure 5 (a) is the top view. Figure 5 (b) is the rear view. Figure 6 This is a detailed view of the elevator car wall in Implementation Method 2. Figure 6 Show Figure 5 Part D. Figure 6 (a) is a top view. Figure 6 (b) is the rear view. Figure 6 (c) is the left view. Figure 7 This is a detailed view of the elevator car wall in Implementation Method 2. Figure 7 Show Figure 5 Part E. Figure 7(a) is a top view. Figure 7 (b) is the rear view. Figure 7 (c) is the left view. Furthermore, for structures identical to the elevator car walls in Embodiment 1, the same reference numerals are used in the drawings, and descriptions are omitted as appropriate thereafter.

[0080] The elevator car 5 is provided with a car car wall 18. The car car wall 18 surrounds the car car floor 8. The car car wall 18 extends upward from the car car floor 8. The elevator users are protected by the car car wall 18 from going from the interior of the car car 5 to the hoistway 1.

[0081] The car wall 18 includes a surface panel 19, a reinforcing member 20, a back panel 21, a clamping member 22, and screws 23. The car wall 18 is, for example, symmetrical from left to right. The vertical direction of the car wall 18 is, for example, the long side direction.

[0082] Here, the front, back, top, bottom, left, and right sides of the car wall 18 correspond to the front, back, top, bottom, left, and right sides of the car wall 18 when viewed from inside the car room 5. The surface side, back side, upper side, lower side, left side, and right side of the car wall 18 correspond to the surface side, back side, upper side, lower side, left side, and right side of the car wall 18 when viewed from inside the car room 5. The front-back direction, vertical direction, and horizontal direction of the car wall 18 correspond to the thickness direction, height direction, and width direction of the car wall 18 when it is installed in the car room 5.

[0083] The surface panel 19 has an appearance design section 24 and an edge section 25. The edge section 25 has a first edge section 25a and a second edge section 25b.

[0084] The surface panel 19 is identical to the surface panel 10 except that it does not have the groove corresponding to the groove 16c of the surface panel 10 of the elevator car wall in Embodiment 1. The appearance design section 24, the edge section 25, the first edge section 25a, and the second edge section 25b correspond to the appearance design section 15, the edge section 16, the first edge section 16a, and the second edge section 16b of the elevator car wall in Embodiment 1, respectively.

[0085] The reinforcing member 20 is disposed inside the space 26 enclosed by the exterior design section 24 and the surrounding edge 25. The reinforcing member 20 has a side portion 20a. The side portion 20a is provided with a threaded hole 20b.

[0086] The side portion 20a, the threaded hole 20b, and the space 26 correspond to the side portion 11a, the threaded hole 11b, and the space 17 of the elevator car wall in Embodiment 1, respectively.

[0087] The back panel 21 is mounted on the rear side of the surface panel 19. The back panel 21 is located on the left and right sides of the surface panel 19. The back panel 21 forms the outer surface of the car compartment 5. The back panel 21 is separate from the exterior design section 24. The back panel 21 is a curved plate-like component. The left and right back panels 21 are formed symmetrically, for example, in the left-right direction. The back panel 21 has a closing portion 21a and a mounting portion 21b.

[0088] In this example, the structures of the left and right back panels 21 are symmetrical about each other in the left-right direction with respect to the reinforcing member 20. Therefore, the description of the structure of the left back panel 21 is described, while the description of the right back panel 21 is omitted.

[0089] The closing portion 21a extends between the upper, lower, and left edges 25 and the reinforcing member 20. The closing portion 21a extends parallel to the appearance design portion 24, for example. The closing portion 21a is, for example, flat. The closing portion 21a is, for example, rectangular. The closing portion 21a abuts against the side portion 20a of the reinforcing member 20. The closing portion 21a overlaps, for example, the side of the side portion 20a of the reinforcing member 20 opposite to the appearance design portion 24. The closing portion 21a is provided with a hole 21c. The centerline of the threaded hole 20b of the reinforcing member 20 passes through the hole 21c. The hole 21c is, for example, a roly-poly type hole.

[0090] Mounting portion 21b extends from closing portion 21a toward the left edge 25. Mounting portion 21b extends parallel to closing portion 21a, for example. Mounting portion 21b extends from the end of closing portion 21a, for example. Mounting portion 21b is located inside space 26.

[0091] The structure of the closing portion 21a and mounting portion 21b of the left back panel 21 has been described, but by replacing the left edge portion 25 described above with the right edge portion 25, the structure of the closing portion 21a and mounting portion 21b of the right back panel 21 is obtained.

[0092] The clamping member 22 is disposed inside the space 26. The clamping member 22 is fixed to the edge 25. The clamping member 22 and the edge 25 are fixed to the car compartment 5 together by screws. The clamping member 22 is, for example, glued to the edge 25. The clamping member 22 abuts against the exterior design section 24.

[0093] A gap 22a is spaced between the clamping member 22 and the edge 25 on which the clamping member 22 is fixed. For example, the clamping member 22 is spaced between a second edge 25b that is continuous with the first edge 25a on which the clamping member 22 is fixed. The gap 22a opens toward the edge 25 opposite to the edge 25 on which the clamping member 22 is fixed. The gap 22a between the left edge 25 and the clamping member 22 opens to the right. The gap 22a between the right edge 25 and the clamping member 22 opens to the left.

[0094] The clamping member 22 extends towards the edge 25 opposite to the edge 25 where the clamping member 22 is fixed. The left clamping member 22 extends to the right of the left edge 25. The right clamping member 22 extends to the left of the right edge 25.

[0095] The clamping member 22 is, for example, a plate-shaped component formed by the first, second and third pieces to form a groove. The first piece abuts against the appearance design part 24, the second piece is fixed to the first edge 25a, and a gap 22a is left between the third piece and the second edge 25b.

[0096] The mounting portion 21b of the back panel 21 is inserted into the space 26 from the rear side of the car wall 18. The mounting portion 21b of the back panel 21 is inserted between opposing edges 25 toward one edge 25. The mounting portion 21b of the back panel 21 is inserted into the space 26 in the left-right direction of the car wall 18. The mounting portion 21b of the back panel 21 is inserted into the gap 22a. The mounting portion 21b of the back panel 21 is inserted into the gap 22a between opposing edges 25. The mounting portion 21b of the left back panel 21 is inserted into the left gap 22a between the left and right edges 25. The mounting portion 21b of the right back panel 21 is inserted into the right gap 22a between the left and right edges 25. The mounting portion 21b is clamped between the edge 25 and the clamping member 22. Alternatively, the gap 22a can be elastically expanded by inserting the mounting portion 21b. In this case, the clamping member 22 presses the mounting portion 21b against the edge portion 25.

[0097] Screw 23 passes through hole 21c in back panel 21 and is screwed into threaded hole 20b in reinforcing member 20, thereby fastening back panel 21 to reinforcing member 20. In the state where screw 23 is temporarily fastened by being screwed into threaded hole 20b, screw 23 can be inserted and removed relative to hole 21c in back panel 21, and the mounting portion 21b of back panel 21 can be inserted and removed relative to gap 22a after screw 23 passes through hole 21c in back panel 21.

[0098] As described above, the back panel 21 encloses the space 26. The back panel 21 encloses the central, upper, lower, left, and right portions of the space 26. The back panel 21 divides the space 26 and the space of the hoistway 1 located outside the car wall 18. By mounting the back panel 21 to the surface panel 19, the space 26 is enclosed relative to the space of the hoistway 1 located outside the car wall 18.

[0099] Furthermore, the clamping member 22 secures the back panel 21 to the surface panel 19. The back panel 21 is secured to the edge 25 in a detachable manner by being clamped by the clamping member 22.

[0100] Furthermore, when installing the back panel 21 onto the surface panel 19, the mounting portion 21b is inserted into the gap 22a while maintaining contact with the clamping member 22. The back panel 21 is guided to move toward the gap 22a by contacting the clamping member 22 from the back side of the car wall 18.

[0101] The elevator car wall in Embodiment 2 includes: a surface panel 19 fixed to the car 5 such that its surface side faces the inside of the car 5 and its back side faces the outside of the car 5; a back panel 21 mounted on the back side of the surface panel 19; and a clamping member 22 that fixes the back panel 21 to the surface panel 19. The surface panel 19 has: an appearance design section 24 that forms the inner surface of the car 5; and an edge section 25 that extends from the outer edge of the appearance design section 24 to the outside of the car 5. The clamping member 22 is disposed inside the space 26 enclosed by the appearance design section 24 and the surrounding edge section 25, and is fixed to the edge section 25. The back panel 21 is disposed separately from the appearance design section 24 and is fixed to the edge section 25 in a detachable manner by being clamped by the clamping member 22, and the space 26 is enclosed.

[0102] Therefore, the back panel 21 can be easily installed and removed from the back side of the surface panel 19. By installing the back panel 21 onto the surface panel 19, the space 26 enclosed by the appearance design section 24 and the surrounding edge 25 of the surface panel 19 can be sealed off, making it difficult for external noise from the car room 5 to be transmitted into the interior of the car room 5.

[0103] Furthermore, by removing the back panel 21 from the surface panel 19, it is possible to easily remove, for example, the screws that attach the surface panel 19 to the car compartment 5.

[0104] Furthermore, since the back panel 21 forming the outer surface of the car room 5 is separately mounted on the surface panel 19 from the exterior design section 24, it is possible to prevent external noise from the car room 5 from being transmitted into the interior of the car room 5.

[0105] Furthermore, since the back panel 21 is not pressed against the appearance design section 24, the appearance design section 24 does not flex, thus suppressing the reduction of appearance design.

[0106] In addition, the back panel 21 is fixed to the surface panel 19 in a detachable manner, so the base materials of the surface panel 19 and the back panel 21 are not fixed or joined to each other, making it difficult for external noise from the car cabin to be transmitted into the interior of the car cabin.

[0107] Furthermore, the back panel 21 is fixed to the surface panel 19 inside the space 26 of the surface panel 19 using a clamping member 22, thus making the back of the car wall 18 smooth and reducing the wind noise generated when the car 5 travels inside the hoistway 1.

[0108] Furthermore, the back panel 21 is inserted into the space 26, so even if the back panel 21 is lowered, it is supported by the surface panel 19, making it difficult to detach from the surface panel 19.

[0109] Furthermore, the surface panel 19 is fixed to the car compartment 5, while the back panel 21 is not fixed to the car compartment 5 but is fixedly mounted to the surface panel 19. Therefore, for example, when the car compartment wall 18 is pressed from the inside of the car compartment 5, the surface panel 19 functions as a support member, and the back panel 21 may not function as a support member. Thus, it is possible to suppress the increase in weight of the back panel 21.

[0110] Furthermore, by fixing the surface panel 19 to the car compartment 5 and then installing the back panel 21 onto the surface panel 19, the weight of the transported components can be reduced compared to fixing the back panel to the car compartment wall beforehand.

[0111] In the elevator car wall of embodiment 2, the clamping member 22 is separated from the edge 25 on which the clamping member 22 is fixed by a gap 22a. The gap 22a is open toward the edge 25 opposite to the edge 25 on which the clamping member 22 is fixed. The back panel 21 is clamped between the edge 25 and the clamping member 22 by inserting the mounting part 21b from between the opposing edges 25 into the gap 22a.

[0112] Therefore, when the back panel 21 is installed on the surface panel 19, on the back side of the surface panel 19, the back panel 21 moves from between the opposing edges 25 toward one edge 25. Thus, it is not necessary for the back panel 21 to extend outwards relative to the surface panel 19 in the up, down, left, and right directions, reducing the space required for movement of the back panel 21. In particular, this is effective when the back panel 21 is installed on the surface panel 19 inside the hoistway 1, with the surface panel 19 fixed to the car compartment 5.

[0113] Furthermore, when the back panel 21 is inserted into the gap 22a, it is inserted in the direction along the side of the closed portion 21a of the back panel 21, so the back panel 21 is difficult to bend and the back panel 12 can be easily mounted on the surface panel 10.

[0114] Furthermore, since the closing portion 21a and the mounting portion 21b of the back panel 21 extend in the same direction, the back panel 21 can be made thinner, making it easier to handle goods on the back panel 21.

[0115] In the elevator car wall of embodiment 2, the clamping member 22 extends from the edge 25 where the clamping member 22 is fixed to the edge 25 opposite to the edge 25 where the clamping member 22 is fixed, and the back panel 21 is inserted into the gap 22a while maintaining contact with the clamping member 22.

[0116] Thus, the back panel 21 is reliably clamped and fixed to the surface panel 19 by the clamping member 22, so that the back panel 21 can be easily installed on the surface panel 19.

[0117] In embodiment 2, the clamping member 22 abuts against the exterior design section 24 in the elevator car wall.

[0118] As a result, when the exterior design section 24 is pressed from inside the car compartment 5, the deflection of the exterior design section 24 is reduced, thereby increasing the user's sense of security.

[0119] In embodiment 2, the clamping member 22 and the edge portion 25 are fixed to the car compartment 5 together with screws in the elevator car compartment wall.

[0120] Therefore, by using screws to fix the edge 25 to the car compartment 5, the clamping member 22 can be firmly fixed to the edge 25, thereby reducing product costs.

[0121] Alternatively, in the elevator car wall of Embodiment 2, the back panel 21 can also be divided vertically. The divided back panels 21 are fixed to the reinforcing member 20, for example, by screws 23. If the divided back panels 21 are closed to each other by the reinforcing member 20, the divided back panels 21 may not need to abut against each other.

[0122] In this case, the back panel 21 becomes smaller and lighter, thus making it easier to handle goods on the back panel 21.

[0123] Additionally, in the elevator car walls of Embodiments 1 and 2, sound-absorbing material can also be placed inside spaces 17 and 26. Sound-absorbing material can also be pre-installed on the surface panels 10 and 19 or the back panels 12 and 21. Alternatively, the sound-absorbing material can be installed on the surface panels 10 and 19 after they are fixed to the car 5 and before the back panels 12 and 21 are fixed to the car 5.
