Description

[Detailed description of the invention] This invention relates to an improved structure of an elevator car in which an emergency rescue door is provided on the side wall.

Elevators that service the upper floors of high-rise buildings generally have non-stop sections on intermediate floors that do not have entrances or exits.

In order to quickly and safely rescue passengers in the elevator car in the event of an elevator failure in this section, adjacent elevators are equipped with emergency rescue doors on the side walls of the opposing cars.

First, a conventional elevator cab will be explained with reference to FIGS. 1 to 3.

In the figure, 1 is an emergency rescue door that is installed on the side wall of the car and opens to the inside of the car, 2 is a locking device for closing the rescue door 1 during normal times, and 3 is a door made of the floor of the car. The hinges are fixed respectively to the upper end of the baseboard base 4 installed upright on the first plate-like body and the lower end of the second plate-like body 5 made of the ceiling, and each engages with the upper and lower ends of the rescue door 1. Together, they support the rescue door 1.

Reference numeral 6 denotes a third plate-shaped body made of a wall panel of the car room adjacent to the opening side of the rescue door 1, and has a bent portion 6a bent outward at the edge, and serves as a stopper for the rescue door 1 and as a locking device 2. An engaging portion 6b is provided.

Reference numeral 6' denotes a fourth plate-shaped body made of a wall panel of the car compartment adjacent to the side where the hinge 3 of the rescue door 1 is attached.

That is, the rescue door 1 is connected to the adjacent second to fourth plate-shaped bodies 5. 6.6', it is installed with a certain gap maintained between it and the baseboard base 4, and is mounted so that it can be opened and closed by a hinge 3.

In normal times, it is closed by the locking device 2 between it and the third plate-shaped body 6, forming a part of the side wall of the car.

For this reason, the rescue door 1 and the plate-shaped body adjacent to it are specially designed to incorporate the rescue door 1, such as the engaging part 6b of the locking device 2, a part of the rescue stopper, that is, the bending part 6a, and the mounting part of the hinge 3. The problem was that the manufacturing process was complicated because it required a different shape and processing.

In particular, the second plate-shaped body 6 has a problem in that it has no commonality with other wall panels, resulting in a decrease in productivity.

Moreover, in the car room, the first plate-shaped body, the second to fourth plate-shaped bodies 5, 6° 6', etc. are assembled in the narrow hoistway (not shown) of the elevator, so there is a problem in adjusting the dimensions with the rescue door 1. There was a drawback that it was difficult to assemble the hinge 3 and the locking part with the locking device 2 in a predetermined position, and it required a lot of installation time.

This invention solves the above-mentioned drawbacks and aims to provide an elevator cab with an emergency rescue door that can be easily assembled at the installation site.

An embodiment of this invention will be described below with reference to FIGS. 4 and 5.

In the figure, the same reference numerals as those in Figures 1 to 3 indicate corresponding parts, and 7 is an overbody integrally formed by vertical frames 7a, 7b, upper frame 7C, and lower frame 7d, and this is attached to the outside of rescue door 1. are arranged to surround the

In addition, rescue doors 1 are provided on the upper frame 7c and lower frame 7d of this frame body 7.
A hinge 3 for opening and closing the rescue door 1 is fixed thereto, and an engaging portion 7e of a locking device 2 for closing the rescue door 1 is provided on the vertical frame 7a on the opposite side of the hinge 3.

Moreover, the frame body 7 is a first plate-like body, second to fourth plate-like bodies 5.
6.6' is fastened with bolts 8 and nuts 9.

That is, the rescue door 1, the locking device 2, and the hinge 3 are incorporated inside the frame body 7 to form an integrated door device 10, and when the rescue door 1 is closed when installed in the car compartment. The frame body 7 is arranged so as not to be visible from inside the car.

This allows the door device 1 to be assembled in advance at the installation site.
0 are placed adjacent to each other in the same way as other wall panels, that is, plate-like bodies, and only need to be fastened together using bolts 8 and nuts 9, and the rescue door 1 can be easily placed in a predetermined position on the side wall of the car compartment. Can be installed.

Therefore, difficult assembly and adjustment work within the narrow hoistway of the elevator can be omitted and installation time can be shortened.

In addition, since the door device 10 can be pre-assembled and adjusted in a factory etc., the installation accuracy of the rescue door 1 can be improved compared to the conventional method, and the plate-shaped body adjacent to the door device 10 has a special Since it does not require any shape or processing, it can be manufactured in the same way as other plate-shaped bodies, and productivity can be improved.

Note that when the rescue door 1 is closed, the shell 7 and the like cannot be seen from inside the car, so that a car that has the same aesthetic appearance as a conventional car can be obtained.

As explained above, this invention incorporates the emergency rescue door, which is provided on the side wall of the car and forms part of the side wall when the door is closed, into the frame body, and forms an integrated door device. The cage is constructed by fastening the cage to an adjacent plate-shaped body via the cage.

As a result, the installation time can be shortened, and an elevator cab with an emergency rescue door can be realized with high assembly accuracy and productivity.
