Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a joint provided between the side panels of an elevator car.The conventional joint of the elevator car is as shown in FIGS. 1 and 2.
The corner joint 3a between the side plates 1a and Ib in the corner part and the intermediate joint 3b between the side plates 1b and 2 in the middle part required different structures. In addition, the holes for the bolts for attaching the side plates were located at different positions for the side plate 1b and the other side plates 1a and 2, resulting in poor productivity. Furthermore, in a car to which the decorative board 4 is attached, when it becomes necessary to replace the decorative board 4, it is necessary to disassemble all the side panels, which is disadvantageous in that it requires a great deal of labor and time.

The present invention has been made in view of the above points, and it is possible to make the partial corner joints and the intermediate joints the same shape, reduce the types of side panels in the corner portions, and create a decorative board without disassembling the side panels. This provides a joint structure that can be replaced.

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 3 and 4. First, the side plates 6a and 6b of one corner are connected by a bracket 5 whose both sides are bent at an angle of 135 degrees. This bracket 5 has a tapped hole 7 for attaching a joint, and the joint 8 is fixed to the bracket 5 through the tapped hole 7 with a countersunk screw 9. In addition, decorative board 4
When installing, the decorative board 4 is inserted and the joints 8 are installed. A groove 10 is provided in the center of the surface of the joint 8, and after fixing the joint 8 to the bracket 5, a color tape 11 or the like is pasted along this groove 10 in order to hide the head of the countersunk screw 9. Consideration has been given to the design.

To create and attach one joint in the middle part, bend the end bent part 61 of the side plate 6b outward, provide a tapped hole 12 for joint attachment in this part, and use the joint 81 with a countersunk screw 9.
The intermediate side plates 20 are fixed by being sandwiched therebetween. Incidentally, instead of providing tapped holes in the bracket 5 and the bent portion 61, a round hole may be provided and a nut may be welded to the back surface.

Further, as shown in FIG. 5, the end/bent part 62 of the side plate 6b is bent inward like the other bent part 63,
If it is connected to the bent portion 21 of the side plate 20 via the bracket 70, all the corner side plates can have the same shape. Furthermore, it is also possible to fix only the end bent portion 62 and the bracket 70 and sandwich the intermediate side plate 2° between the joint 8 and the bracket 70.

As explained above, according to the present invention, the same part of the corner joint and the middle joint can be used, and the part of the corner side plates 6b, 6c, 6. d and 6a, 6e.

Productivity and workability are improved because the same material can be used for each of the 6Fs, and the decorative board 4 can be removed simply by removing the joints 8.
Since the side plates 20 can be replaced and the side plates 20 can be removed, installation and maintenance are extremely easy. Furthermore, by changing the bending direction of the end portion of the corner partial side plates, all the corner partial side plates can be made the same.
