Description

[Detailed description of the invention] This invention relates to an improvement of an elevator cab.

It has been proposed to use panel bodies with intervening lightweight fillers for the walls of elevator cabs.
This is illustrated in FIGS. 1 and 2.

In the diagram, 1 is the elevator car floor, 2 is the car floor 1
2a is a front plate of the panel body 2, 2b is a back plate facing the front plate 2a across a space, and the front plate 2a and the back plate 2b form a box. A shaped body is formed. 2c is a lightweight filling material such as urethane foam filled in the space; 3 is a nut fixed to the back surface of the top plate 2a; 4
is a handrail placed horizontally in front of the top plate 2a, 5 is a support fitting fixed to the back side of the handrail 4, 6 is a bolt screwed into the nut 3 to fasten the support fitting 5 to the top plate 2a, and 7 is a panel body. The ceiling is attached to the upper end of 2, and 8 is a car door that opens and closes the car entrance.

That is, the cage wall is formed of a lightweight panel body 2 with a filler 2c interposed therein, and protrusions such as the handrail 4 are fixed to this. Since adhesive force is exerted to some extent between the top plate 2a and the filler 2c, even if a normal load (especially downward) is applied to the handrail 4, it is possible to withstand this.

However, if an abnormal load is applied to the handrail 4, for example in a downward direction, the adhesive surface A of the top plate 2a and the filler 2c will peel off, causing deformation of the top plate 2a.

This idea improves the above problem by fixing reinforcing material extending into the filler to the back side of the front plate of the panel body, so that even if a large load is applied to the front plate, the front plate will remain intact. It is an object of the present invention to provide an elevator cab in which a peeling phenomenon does not occur between fillers.

An embodiment of this invention will be described below with reference to FIG.

In the figure, 9 is a steel plate formed in a Z-shape, one end of which is in contact with and fixed to the back surface of the top plate 2a, and the other end is a reinforcing member extending into the filler 2c. Other than this, it is the same as in FIGS. 1 and 2.

That is, since the other end of the reinforcing material 9 extends into the filling material 2c, the strength of the reinforcing material 9 itself and the filling material 2 at the contact surface B between the reinforcing material 9 and the filling material 2c are
Due to the yield strength of c, even if a large load is applied to the handrail 4, peeling will not occur between the top plate 2a and the filler material 2c. Therefore, no deformation of the top plate 2a occurs.

In the embodiment, the panel body 2 forming the car wall is shown, but it is obvious that the present invention can also be applied to a panel body forming the car door 8.

As explained above, in this invention, the panel body used in the elevator cab is composed of a top plate, a back plate, and a lightweight filler interposed in the space formed between them, and the members protruding from the top plate are A reinforcing material is fixed to the back side of the part fastened to the top plate, and a part of the reinforcing material extends into the filler and faces the back side of the top plate, so even if a large load is applied to the above member, the top plate will not be damaged. It is possible to eliminate the peeling phenomenon that occurs between the filler and the filler, and prevent deformation of the top plate.
