Description

DETAILED DESCRIPTION OF THE INVENTION OBJECTS OF THE INVENTION (Industrial Field of Application) The present invention relates to an elevator cab structure, and more particularly to an elevator cab structure in which the connection method of side plates of the cab is improved.

(Prior Art) As shown in FIG. 3, a conventional elevator car has entrance/exit pillars 2, 2 and a plurality of side plates 3 on the periphery of the E side of the car floor 1.
are lined up and erected through middle books (not shown), and the adjacent entrance pillars 2 and side plates 3 are connected and assembled, and a ceiling (not shown) is attached to the top. It is the composition.

Note that 4 in the figure indicates an entrance/exit door.

Here, each of the side plates 3 has a bent edge 3a projecting outward (on the back side) like a flange, and the bent edge 3a is joined to the adjacent one, as shown in FIG. bolt 5
The side plates are connected to each other by fastening with nuts 6 and 6.

(Problem to be solved by the invention) By the way, in the conventional elevator car structure described above,
The bent edge 3a of each side plate 3 protruding outward is joined to the adjacent one and connected by fastening with bolts 5 and nuts 6, so the bolts 5 and nuts 6 for the connection are inserted from inside the car. It is completely invisible, and the aesthetics and design of the car interior are improved. However, with such a car interior structure, the work of connecting the side plates 3 to each other is difficult. This work requires workers to use tools such as spanners in a narrow space, resulting in extremely dangerous and inefficient work, which poses problems such as increased costs for on-site assembly and installation. In other words, the space between the outside of the car and the inner wall of the hoistway is narrow, and there are only a few places where people can enter and work, so for example, multiple side plates 3 on the left and right sides are connected and assembled indoors in advance, and each car floor is 1, and the remaining side plate 3 on the tuition side of the car is finally placed upright on the car floor 1,
The side plates 3 were connected to each other by bolts 5 and nuts 6 by a worker entering a place outside the car outside where people could easily enter, for example, a counterweight side space. For this reason, the connection work in the narrow space outside the car was extremely dangerous and inefficient (and the cost of assembling and installing it on site increased accordingly).

The present invention has been made in view of the above circumstances, and provides an elevator car structure in which the mutual connection and assembly of side plates installed on the car floor can be performed more safely and efficiently than in the car interior, and assembly and installation on site is extremely simple. The purpose is to provide.

[Structure of the invention]

(Means for Solving the Problems) In order to achieve the above object, the elevator car structure of the present invention has protrusions protruding from the bent edges of either one of the adjacent side plates, and A feature is that a hook-shaped groove is formed in the curved edge, and the adjacent side plates can be connected to each other by fitting the hook-shaped groove to the protrusion.

(Function) With the above configuration, the side plates that are arranged side by side on the car floor can be connected to each other by the protrusion protruding from the bent edge of one side and the bent edge of the other side without using fasteners such as bolts or nuts. Since the side plates can be connected by fitting into the formed hook-shaped grooves, the work of connecting the side plates to each other can be done more safely and efficiently than inside the car, and assembly and installation on site are extremely simple.

(Example) An example of the present invention will be described below with reference to FIGS. 1 and 2. Note that the overall configuration is the same as that shown in FIG. 3, so illustration is omitted. Here, Fig. 1 shows three side plates 3A and 3B installed in a row on the tuition fee side of the basket (opposite the entrance/exit side).
, 3C is an exploded perspective view showing the upper half portions of the side plates 3A, 3B.

3C has a structure having bent edges 3a, 3b, and 3c projecting outward in a flange shape on both sides in the width direction, respectively. The bent edges 3a and 3c of the side plates 3A and 3C on both sides, excluding the middle side plate 3B, have protrusions 7 at their upper and lower ends (the lower end is not shown). Two of them are installed with a small interval above and below.

Each of these protrusions 7 has a bent edge 3a as shown in FIG.

It is stacked by fitting the small diameter neck part 7a into the mounting hole 8 formed in 3C, and there is a stepped part 7b with a slightly larger diameter on the tip side of the small diameter neck part 7a, and a tapered part on the further tip side. It has a structure that integrally has a head portion 7C which has a large diameter through a portion. On the other hand, on both bent edges 3b, 3b of the intermediate side plate 3B, small spaces are provided vertically at the upper and lower end portions (lower end portions are omitted from illustration) in order to correspond to the protrusions 7, respectively. Individual hook-shaped grooves 9 are formed. This hook-shaped groove 9 is bent into an abbreviated shape on the bent edge 3b, and the groove width is smaller than the diameter of the head 7c of the protrusion 7.
The size is such that it just fits into the stepped portion 7b of the protrusion 7.

Note that the width of the lower opening of the piece-shaped groove 9 is made slightly wider so that the stepped portion 7b of the protrusion 7 can be easily inserted.

Therefore, if the elevator car has the above-mentioned structure, the second and third
As shown in the figure (multiple side plates 3 on the left and right sides on the car floor 1)
. . . are connected and assembled indoors in advance in the same manner as before, and then set up and fixed upright. At this time, the central side plate 3B is left out of the three on the back side, and the side plates 3A and 3C on both sides are also connected in advance to the left and right side plates 3 and fixed in an upright position at a predetermined position. In this state, the last remaining central side plate 3B is fitted between the side plates 3A and 3C on both sides while being slightly lifted from the inside of the car, and the hook-shaped grooves 9 on both bent edges 3b, 3b are inserted on both sides. side plate 3A, 3
Fit it with the stepped part 7b of the protrusion 7 of C, push it in a little, and then drop it downward. Now, the upper end of each hook-shaped groove 9 is fitted into the stepped portion 7b of the protrusion 7, and the side plate 3 is fitted with no looseness or play.
A, 3B, and 3C are connected to each other. All the side plates 3 are completed above.
... can be easily carried out on the car floor 1 in the car interior, making on-site assembly and installation extremely safe and efficient.

Note that the present invention is not limited only to the above embodiments,
For example, the hook-shaped grooves 9 are formed in the bent edges 3a and 3c of the side plates 3A and 3C on both sides, and the bent edges 3b on both sides of the central side plate 3B are formed.
It is also possible to configure the protrusion 7 by protruding it. In addition to the side plates 3A, 3B, and 3C installed upright on the rear side of the car, a plurality of side plates 3 on the left and right sides may be connected to each other by the projections 7 and the hook-shaped grooves 9. It's a bow. Furthermore, the side plates of the car safety lever may be erected one by one while being connected to the projections 7 and the hook-shaped grooves 9.
