Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a joint provided between side plates of an elevator car.

As shown in FIGS. 1 and 2, the joints of conventional passenger cars are a corner joint 3a between the side plates 1a and 1b at the corner, and an intermediate joint 3b between the side plates 1b and 2 at the middle. I needed something with a different structure. In addition, the holes for the bolts for attaching the side plates are drilled in different positions from the side plate 1b and the other side plates 1a and 2, and the side plates 1b and 1c are oppositely positioned, so three types of corner side plates are required. Productivity and industrial efficiency were poor. Furthermore, decorative board 4
If it becomes necessary to replace the decorative board 4 of a car with the car attached, it is necessary to disassemble the side board.
The drawback was that it required a lot of effort and time.

The present invention has been made in view of the above points, and has the same shape as the corner joint and the intermediate joint, reduces the number of types of side panels at the corner, and allows replacement of the decorative board without disassembling the side panels. This provides a joint structure that can be used.

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

To attach the joint in the middle part, bend the bent end part 61 of the side plate 6b outward, provide a tap hole 12 for joint attachment in this part, and fix the middle part side plate 20 with the joint 8 countersunk screw. It is something to do. Incidentally, instead of providing tap 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, if the end bent portion 62 of the side plate 6b is bent inward like the other bent portion 63 and connected to the bent portion 21 of the side plate 20 via the bracket 70, All corner side plates can now have the same shape. Furthermore, it is also possible to fix only the end bent portion 62 and the bracket 70 and sandwich the middle side plate 20 between the joint 8 and the bracket 70.

As explained above, according to the present invention, the same corner joint and intermediate joint can be used,
Also, corner side plates 6b, 6c, 6d and 6a,
Since the same parts 6e and 6f can be used, productivity and workability are improved, and installation and maintenance are extremely easy because the decorative board 4 can be replaced and the side panels 20 can be removed by simply removing the joints 8. I can do it. Further, by changing the bending direction of the corner side plate ends, all the corner side plates can be made the same.

Claims (1)

[Claims] 1. In a case where the side panels of an elevator car are divided into a plurality of parts, the side panels at the corners of the car should have joint mounting holes in the center, and each side panel should be in contact with the side panels of the corner sections. They are connected by a bent first bracket, and the middle side plates are connected by a flat second bracket having a joint attachment hole in the center, or the end of one side plate has a joint attachment hole. The bent portion is overlapped and connected to the end of the other side plate, and the corner joint and the intermediate joint are connected by providing a groove at the top of the joint material with a T-shaped cross section and holes for countersunk screws at predetermined intervals. The joints are connected to the mounting holes of the first bracket through the holes at the corner portions, and to the bent portions of the end portions through the holes at the intermediate portions. A joint structure for an elevator car, characterized in that the joint structure is screwed into the mounting hole of the second bracket or the mounting hole of the second bracket.
