Problems solved by technology

[0005] However, in the case of using bolts, it takes time to join, it is impossible to work from inside the car, and assembly requires fine adjustments, which is very difficult
In addition, in the case of using clips, although the work time can be greatly shortened, the problem of a large number of parts has not been solved.
In addition, in the case of the structure using the wedge effect, there is a problem that the panel is easy to fall off when a force acts in the direction opposite to the insertion direction.

Embodiment approach 1

[0023] exist figure 1 Among them, the car panel 2 has: a first joint edge portion 11 that should be combined with the adjacent car panel 3; and a second joint edge portion 12 that should be combined with the adjacent car panel, that is, the entrance and exit panel 8. 2 The joint edge portion 12 is located at the side edge on the opposite side of the first joint edge portion 11, the first groove-shaped bending portion 13 is provided on the first joint edge portion 11, and the second groove-shaped bending portion 13 is provided on the second joint edge portion 12. 2 Groove-shaped bending part 14. Similarly, first and second joining edge portions 11 and 12 and first and second groove-shaped bending portions 13 and 14 are also provided on the car panels 3 to 7 .

[0024] On the second groove-shaped bending portion 14 of the car panel 2, the only bending edge provided on the only combining side edge 15 (corresponding to the first combining edge portion 11) of the entrance and exi...

Embodiment approach 2

[0036] According to the panel joint structure of the elevator car of the present invention having such a structure, even when the car panels 3 and 4 and between the car panels 5 and 6 constituting the corners of the car room 1 are combined, the same structure as before can be achieved. about figure 1 and figure 2 The same effect as the structure described above.

[0037] Embodiment 3

[0038] exist Figure 4 In , another example of the joint structure that can be used for the corner of the car 1 is shown. In this example, the connecting part 21 of the first groove-shaped bending part 13 of the car panel 3 The body portion extends linearly. In such a case, it is also possible to obtain image 3 same effect as the case.

Embodiment approach 3

[0040] Embodiment 4

[0041] exist Figure 5 In , an example in which the same car panel can be used for both the flat part and the corner part of the wall is shown as a modified example of the panel coupling structure of the elevator car according to the present invention. In the panel combination structure of the elevator car, such a structure is shown: the depth D of the first groove-shaped bending portion 13 of the car panel 2 (viewed from the inside of the car 1, the inside of the car panel 2 from the inside The distance from the inner surface of the bottom wall 23) is equal to the width B of the interior space (the length of the bottom wall 23 between the first and second side walls 22, 24), so that the second groove-shaped bending portion of the car panel 3 The height H of 14 (the distance from the inner surface of the car panel 3 to the outer surface of the bottom wall 30) and the outer width C of the main body portion (the distance between the outer surfaces of the f...

Abstract

A structure for joining panels of an elevator car together. A first groove-shaped folded section is provided at a joint edge section of a first car panel, and the first groove-shaped folded section has a groove-shaped cross-section having an opening and an inner space having a width greater than the width of the opening.A second groove-shaped folded section is provided at a joint edge section of a second car panel, and the second groove-shaped folded section has a body width greater than the width of the opening of the first car panel and smaller than the width of the inner space. The second groove-shaped folded section is press fitted into the inner space through the opening of the first groove-shaped folded section, and the two groove-shaped folded sections are elastically joined and held together. The first groove-shaped folded section has a first side wall along the joint edge section, a bottom wall, and a second side wall, and is formed along the inner space and opening joint edge sections. The second groove-shaped folded section may have a shape similar to the first groove-shaped folded section or may have two side walls folded back and superposed over each other.

Description

technical field [0001] The invention relates to a panel combination structure of an elevator car. Background technique [0002] In an elevator car, car panels such as wall panels are used to form a car compartment. In order to combine the panels of the car together, in the past, the joint edges of the panels were bent to form fastening parts, and the fastening parts were fastened together with fasteners such as bolts or clips. This technique is common. revolutionary technology (for example, refer to Patent Document 1). In addition, in order to couple wall panels together without using fasteners, there has been proposed a structure in which a wedge shape is provided at a panel joint and the panel is joined by this wedge effect (for example, refer to Patent Document 2). [0003] Patent Document 1: Japanese Patent Application Laid-Open No. 9-77431 [0004] Patent Document 2: Japanese Patent Laid-Open No. 2001-302149 [0005] However, in the case of using bolts, it takes tim...
