Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an elevator cab, and more particularly to an elevator cab with an improved side plate forming a peripheral wall.

[Background of the invention]

xv＜−□. The car room □ is shown in Figure 1. As shown in Figure 1, the car floor 2. Side plate 4 forming the peripheral wall of the car n39. Pillar 5,
It is composed of a top plate 6. In order to ensure the safety of elevator operation, these cab members are required to have a structure that prevents them from falling apart into the hoistway. Of these, the car floor 2 and the car master 3 are directly connected to a car frame 8 that supports the car room 1 and moves up and down within the hoistway guided by guide rails 7, so that they do not fall into the hoistway.

As shown in FIG. 1, the top plate 6 always engages with the vertical frame 9 of the car frame 8 via a stopper 10. 4d, and the adjacent front panels are connected with flanges provided on both sides in the width direction with bolts 11, as shown in Fig. The pillar 5 is connected to the car floor 2 with bolts 11 to prevent it from falling into the hoistway. In addition, the lower horizontal reinforcement body 4C is attached to the floor 2 with a basket.
The upper horizontal reinforcement 4b is connected to the ceiling 6 with bolts, and only the vertical reinforcement 4d, which cannot be connected with bolts, is the front panel 4a and the horizontal reinforcement 4b.

By welding it to 4C, it prevents it from falling into the hoistway.

However, such a welded joint always causes distortion, which impairs the design, and requires a lot of time to correct the distortion. In order to eliminate this welding work, the front panel 4a and the vertical reinforcement body 4d.

It is conceivable to attach the lateral reinforcement bodies 4b and 4c with adhesive. (Utility Model Application No. 58-134376) When mounting by adhesive, the front panel 4 is attached as shown in the figure.
Since a soft adhesive layer 12 is formed between a and the reinforcing body 4d, vibration damping properties are improved compared to conventional welded structures, but on the other hand, reliability in terms of strength is lowered. Therefore, in the conventional structure, the vertical reinforcement 4d cannot be attached only by gluing, but must be joined to the horizontal reinforcements 4b and 4c by welding as shown in Figure 7, making it impossible to eliminate strain correction work. There was a problem.

[Purpose of the invention]

An object of the present invention is to provide a side plate that is easy to manufacture and has high safety.

[Summary of the invention]

In order to achieve the above object, the present invention includes a car floor, a peripheral wall erected at the periphery of the heel floor, a top plate provided at the upper end of the peripheral wall, and a top plate formed on a part of the peripheral wall. In a car compartment equipped with a car door that opens and closes an entrance, the peripheral wall is composed of a plurality of side plates made of steel plates having flanges on both sides in the width direction, and each side plate has horizontal reinforcing bodies long in the width direction at the upper and lower ends of the back surface thereof. At the same time, in the vertical direction of the back surface, a vertical reinforcing body located between the upper and lower horizontal reinforcing bodies is attached by adhesive, and a fall prevention piece of the vertical reinforcing body is attached to each of the upper and lower horizontal reinforcing bodies. and the upper and lower horizontal reinforcement bodies are bolted to the top plate side and the car floor side, respectively.

[Embodiments of the invention]

/ F Hereinafter, one embodiment of the present invention will be explained with reference to FIGS. The horizontal reinforcing body 4b is bent and extended to form a fall prevention securing piece 4e that engages with the vertical reinforcing body 4d.

4C are attached by bonding their U-shaped bottom portions with adhesive. As shown in FIG. H, this retaining piece 4e is arranged so as to overlap the upper and lower ends of the vertical reinforcing body 4d by the L dimension. With such a structure, as shown in Figure H, the vertical reinforcing body 4d and the front panel 4a
Even if the adhesive peels off and you try to fall, the upper and lower horizontal reinforcements 4
b.

4C, and the outside is held down by the fall prevention retaining piece 4e, the fall is restricted and the vertical reinforcement body 4d does not fall into the hoistway.

On the other hand, each horizontal reinforcement body 4b prevents the vertical reinforcement body 4d from falling;
Bolt through holes are provided in the parts of 4c that face the top plate and the car floor, and the bolts are connected to the top plate and the car floor, so even if the adhesive between the horizontal reinforcing bodies 4b and 4c comes off, it will not fall. , and the clothing panel 4a itself only falls onto the floor, but does not fall into the hoistway.

According to this embodiment, as described above, there is an effect that the vertical reinforcing bodies 4d and the horizontal reinforcing bodies 4b, 4C of the side plate 4 can be prevented from falling without requiring a welded structure.

Further, according to this embodiment, since the fall prevention retaining piece 4e can be used as a handle when assembling and transporting the side plate, there is no risk of damaging the design surface of the side plate during transport, and there is also the effect that transport is facilitated. .

In this embodiment, a U-shaped vertical reinforcing body 4d is exemplified, but it is clear that the same effect can be obtained by using an L-shaped, hat-shaped, inverted hat-shaped, etc.

Figures N and H show other embodiments of the present invention, in which a fall prevention retaining piece 4e provided at one end of the U-shape of the horizontal reinforcements 4b, 4c corresponds to the vertical reinforcement 4d. It is provided only at one position and engaged with the vertical reinforcing body 4d, and has the same effect as the first embodiment.

〔Effect of the invention〕

According to the present invention, it is possible to eliminate the welding work of the side plates and prevent the reinforcing body from falling, so that the safety of the side plates can be ensured and manufacturing can be facilitated.
