Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an elevator car, and particularly to an elevator car whose side walls are constructed by connecting a plurality of enamel plates to each other.

[Background of the invention]

The side walls of an elevator car are visible to users, and are required to have a certain level of aesthetic appeal in terms of color and other aspects.

On the other hand, the side walls of elevator cars are easily scratched by loads being loaded onto them, and relatively often have graffiti written on them, or scratches and stains caused by mischief by users.

From this point of view, the side walls of elevator cars are made of, for example, stainless steel to make them less susceptible to graffiti and to prevent them from being easily scratched by items such as luggage. Stainless steel material is almost satisfactory in terms of strength, but it has limitations in color and aesthetics.

On the other hand, enamel materials have recently been attracting attention as construction materials for housing equipment such as buildings. Enamel wood has the advantage of being highly fire resistant, hardly causing any damage due to objects hitting it, and being rich in color with little deterioration of color.

Therefore, it has been proposed to use enamel material for the side walls of elevator cars.

FIG. 4 shows the cross-sectional structure of the enamel plate. After coating the base metal 6 with a glaze 7 and drying it,
The enamel plate 1 is formed by firing at a temperature of 800°C to 850°C. Therefore, the base metal 6 is attached to the enamel plate 1.
Firing distortion occurs due to the difference in thermal expansion coefficient of the powder powder 7.

For this reason, when using enamel plates for the side walls of the elevator, as shown in the plan view of Figure 3, the widths D ₁ and D ₂ must be such that the negative effects of firing distortion will not occur.
It is necessary to connect and connect the divided enamel plates 1a, 1b, . . . to each other to form the side wall. In this case, the width of the division should be approximately 300 to 500 mm.
It is known that there is no adverse effect of firing distortion.

In this case, the enamel plates 1a and 1b were joined and connected as shown in FIG. That is, the ends of the first and second enamel plates 1a, 1b are bent at right angles in the same direction, and these bent portions serve as the first and second joints 11 and 12, respectively.

The first and second joint parts 11 and 12 are brought into contact with each other, and the bolt 4a is provided passing through these joint parts, and the first and second joint parts are connected using a spring washer 4b and a nut 4c. The enamel plates 1a and 1b are fastened together at the joint.

In the side walls of conventionally proposed elevators constructed in this way, stress is concentrated at the bent corner R for forming the joint, and the glaze 7 on the enamel plates 1a and 1b tends to peel off. There is. Further, a direct load acts on the glaze 7 of the first and second joints 11 and 12, which are fastened in direct contact with each other. For this reason, there was a drawback that the glaze cracked and was destroyed at the first and second joint portions 11 and 12. In addition, there is Utility Model Application Publication No. 50-136159 as a technology related to elevator cars.

[Purpose of the invention]

The present invention solves the drawbacks of the previously proposed methods described above, and provides an elevator car that prevents the glaze from falling off of the enamel plates that are connected to each other and protects the joints. The purpose is to provide.

[Summary of the invention]

In order to achieve the above-mentioned object, this invention:
In an elevator car whose side walls are formed by joining and connecting a plurality of enamel plates, a first joint of a first enamel plate and a second joint of a second enamel plate that face each other and a shielding piece arranged to cover the first joint part and the second joint part, and an insertion piece arranged between the first joint part and the second joint part. A joint is provided, and an interposer for suppressing frictional noise is arranged between the insertion piece of the joint, the first joint part, and the second joint part.

[Embodiments of the invention]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below based on embodiments thereof using drawings.

The configuration of the main parts shown in FIG. 1 is an embodiment of the present invention, and the first and second joint parts 11 and 12 are joined and connected to each other with an intervening body 15 disposed between them. are doing.

That is, in the embodiment shown in FIG. 1, this intervening body 15 is composed of the joint 3 and the intervening bodies 2a and 2b.

The joint 3 is composed of an insertion piece 16 disposed between the first and second joint parts 11 and 12, and a cover piece 17 extending integrally from the end of the insertion piece 16.
The joint 3 is formed of, for example, a metal material, and the insertion piece 16
are formed to slightly protrude from the ends of the first and second joints 11 and 12. Enamel board 1a, 1
On the bent side of b, the insertion piece 16 is formed to protrude slightly from the plate surfaces of the enamel plates 1a, 1b, and a covering piece 17 is integrally formed at this protruding end.

The shielding piece 17 is extended substantially parallel to the plate surfaces of the enamel plates 1a, 1b so as to closely face them, and connects the first and second joints 11, 12 to the enamel plates 1a, 1b.
It is arranged so as to cover the plate surface side of b. Therefore, the first
In the figure, first and second enamel plates 1a, 1
A distance A is formed between the plate surface b and the shielding piece 17.

Interposers 2a and 2b are filled between both plate surfaces of the insertion piece 16 facing the first and second joints 11 and 12 and the joints 11 and 12. Intermediate body 2a, 2b
For example, felt is used.

It is desirable to use the interposers 2a, 2b that have a small coefficient of friction and do not generate frictional noise due to vibrations during running of the elevator.

With the interposers 2a and 2b filled between both surfaces of the insertion piece 16 of the joint 3 and the first and second joints 11 and 12, a bolt 4a is inserted through these spaces, and a spring washer 4b, The first and second enamel plates 1a and 1b are fastened together at the joint using a nut 4c.

The side wall of the elevator car is constructed as shown in FIG.
Since the bent corner R is protected, the glaze will not peel off due to luggage or the like hitting this part.

Also, since the opposing plate surfaces of the first and second joints 11 and 12 are in contact with the interposers 2a and 2b,
No concentrated load is applied to the glaze 7 of the first and second joints 11 and 12 during fastening. Therefore, the glaze 7 on the joints 11 and 12 will not be destroyed due to cracking.

〔Effect of the invention〕

As explained in detail above, according to the present invention, the glaze at the joint of the enamel plates constituting the side wall is
To provide an elevator car that does not crack or break when connected, the joint part is protected by a joint, and the glaze on the bent part of the enamel plate does not peel off.
