Description

[Detailed explanation of the idea] This invention relates to improvements to elevator corners.

First, a conventional elevator will be explained with reference to FIG.

In the figure, 1 is a car frame made of shaped steel assembled into a mouth shape.
a is the bottom edge of this, 1b is the side edge, 1c is the top edge, 2 is the top edge 1
3 is a support frame placed in the car frame 1; 4 is a brace whose both ends are respectively fastened to the side 1b and the support frame 3; 5 is a main rope connected to the support frame 3; Vibration isolators made of smooth rubber or the like are installed at each of the four corners of the upper surface, 6 is a car floor mounted on top of these, and 1 is a car compartment that is erected on the heel floor 6.

That is, the car floor 6 is vibration-proofly supported by the vibration isolator 5 with respect to the car frame 1 and the support frame 3 to prevent vibrations transmitted from the main ropes 2 and to prevent passengers in the car room 7 from feeling uncomfortable.

However, since the support frame 3 is required for anti-vibration support, the manufacturing cost increases, and as the weight increases, it is necessary to make various elevator equipment corresponding to the weight, resulting in an increase in the cost of the elevator.

This invention solves the above-mentioned drawbacks and aims to provide an elevator car with a simple structure in which the car floor is supported in a vibration-proof manner.

An embodiment of this invention will be described below with reference to FIGS. 2 and 3.

In the figure, the same symbols as in Figure 1 indicate corresponding parts, and 5 is the lower side 1a.
A vibration isolator interposed between the upper surface and the car floor 6, 6a is a support provided at a position away from the side 1b of the edge of the car floor 6, and 4 is a support at the lower end of the support 6a. Bracing inserted loosely into, 8
is made of a cylindrical body and is fitted into the brace 4, and the end face is the seat 6a.
A blocking piece 9 disposed facing the blocking piece 9 is a vibration isolating piece made of rubber and having a cylindrical body whose inner diameter is larger than the outer diameter of the blocking piece 8, and the height of the cylinder is formed to be larger than that of the blocking piece 8. Then, it is fitted into the blocking piece 8 and the end face thereof is placed in contact with the seat 6a.

10 is a washer fitted to the lower end of the brace 4 and the ash receiver of the vibration isolating piece 9 is placed on the seat 6a side, 11 is a nut screwed into the lower end of the brace 4, and 7a is a washer fitted to the upper part of the car room 7. A supporting piece 12 is a supporting piece 7a that stands upright and is placed facing the side 1b.
This is a vibration isolator interposed between the side edge 1b and the side edge 1b.

That is, the center portion of the car floor 6 is vibration-proofly supported on the lower side 1a of the car frame 1 by the vibration isolator 5, and the edge portion is vibration-proofly supported on the side side 1b of the car frame 1 via the braces 4.

Therefore, the support frame 3 shown in FIG. 1 is not required, making it possible to manufacture the car easily and reducing the weight of the car.

Further, when an excessive unbalanced load is applied to the edge of the car floor 6, abnormal deformation of the vibration isolator 9 is prevented by the blocking piece 8, so damage to the vibration isolator 9 can be prevented. .

Furthermore, accidents caused by abnormal inclination of the car floor 6 due to damage to the vibration isolator 9 can be prevented.

As explained above, in this invention, the lower and upper ends of the car frame are connected to the upper side of the car frame and each is vibration-proofly supported by braces arranged diagonally, so that the required requirements can be achieved with a simple structure. The purpose of the present invention is to realize an elevator car that can provide vibration-proofing effects, reduce weight, and reduce the manufacturing cost of the elevator including the car.
