Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an elevator entrance/exit device, and particularly to an elevator entrance/exit device suitable for preventing accidents such as small objects from falling into a hoistway.

<Prior Art> Generally, when an elevator car is landing on a landing, a gap of about 3 cm is often formed between the car sill and the landing sill. For this reason, there is no major danger such as passengers falling, but the bottom of the hoistway is visible through the gap, so if a passenger accidentally drops a small item such as a key, it will enter the hoistway through this gap and the key or other object will fall into the pit. I had a problem with it falling.

To solve this problem, for example, as shown in Japanese Utility Model Application Publication No. 51-160349, a car sill that is fixed at one end of the car floor has a structure that extends along the car sill to the landing side. , a flexible closing body that closes the gap is extended, and
As shown in Japanese Unexamined Patent Publication No. 104146/1983, a car has been proposed in which a movable auxiliary sill is provided on the car sill, and this auxiliary sill is operated when the car lands on the floor to reduce the gap. There is.

<Problem to be solved by the invention> By the way, in the conventional elevator entrance/exit device as described above, in which the former blocking body is provided, the blocking body may interfere with the protruding body of the car door when the car is raised or lowered. In order to avoid this, a notch is provided, and there is a problem in that small objects may fall from this notch. On the other hand, in the latter case, which is provided with an auxiliary sill, it is necessary to install a drive device, a control device, etc. for the auxiliary sill, and there is a problem in that it costs a lot of money.

The present invention was developed in view of the actual state of the prior art, and its purpose is to eliminate the gap formed between the car sill and the landing sill when the car lands over its entire length, without requiring a complicated mechanism. An object of the present invention is to provide an elevator entrance/exit device which can be closed by moving the elevator.

<Means for Solving the Problems> In order to achieve this object, the present invention provides a car with a car sill fixedly attached to one end of the floor of the car, and a car doorway formed above the car sill. , comprising a car door whose lower end is supported by the car sill and opens and closes the car entrance, and a protruding body protruding from the car door, and a landing area on which the car lands;
a landing sill fixedly installed corresponding to the car sill;
A landing entrance/exit formed above the landing threshold;
A landing door whose lower end is supported by the landing sill and opens and closes the landing entrance; and an engaging body that projects from the landing door and engages with the protruding body;
In an elevator entrance/exit device in which a closing body is provided on the car sill and extends along the car sill to the landing side and has a notch in a portion that engages with the engaging body of the landing door, A closure piece is provided which extends along the landing sill toward the car and fits into the notch of the closure body.

<Function> Since the present invention is configured as described above, when the car is raised or lowered, the engaging body of the landing door passes through the notch of the closing body, and the protruding body of the car door passes through the outside of both end surfaces of the closing piece. pass through. On the other hand, when the car lands on the landing, the protruding body of the car door engages with the engaging body of the hall door, and the car door and the hall door perform opening and closing operations in conjunction with each other via these protruding bodies and the engaging body. At the same time, the closing body of the car sill and the closing piece of the landing sill are adapted to fit together. This makes it possible to close the entire length of the gap formed between the car sill and the landing sill when the car lands on the floor, without requiring a complicated mechanism.

<Example> Hereinafter, the elevator entrance/exit device of the present invention will be explained based on the drawings.

1 to 4 are diagrams illustrating an embodiment of the elevator entrance/exit device of the present invention, in which FIG. 1 is a vertical sectional view showing the overall configuration, FIG. 2 is an enlarged vertical sectional view showing the main part configuration, FIG. 3 is an enlarged cross-sectional view of the landing door and the car door, and FIG. 4 is an enlarged plan view of the landing sill and the car sill.

The car 2 that moves up and down in the hoistway 1 shown in FIG. 5, a car entrance 6 formed above the car sill 4, and a car door 7 whose lower end is supported by the car sill 4 and opens and closes the car entrance 6.
and a protruding body 8 protruding from the car door 7. On the other hand, the landing 9 where the car 2 lands on the floor includes a landing sill 10 fixed at the end corresponding to the car sill 4 of the car 2, and a landing entrance 11 formed above the landing sill 10. The lower end is the landing threshold 1
A landing door 12 is supported at 0 and opens and closes a landing entrance 11, and an engaging body 13 projects from the landing door 12 toward the car 2 and engages with a protrusion 8 of the car door 7.

In addition, as shown in Fig. 3, the car sill 4 has
A closing body 14 extending toward the landing 9 side is extended along the car sill 4, and a notch 15 is provided at a portion where the closing body 14 engages with the engaging body 13 of the landing door 12. As shown in FIG. 2, this closing body 14 includes a flexible rubber body 16 that has an L-shaped cross section and closes the gap G between the car sill 4 and the landing sill 10, and an L-shaped body that supports this rubber body 16. It consists of a reinforcing body 17, screws 18 for attaching the rubber body 16 and the reinforcing body 17 to the car sill 4, and the like. On the other hand, as shown in FIG. 4, the landing sill 10 is fitted with a closing piece 19 that extends along the landing sill 10 toward the car 2 and fits into the notch 15 of the closing body 14. For example, as shown in FIG. 2, this closing piece 19 includes a flexible rubber body 20 that has an L-shaped cross section and closes the gap G, and a reinforcing body 2 that supports this rubber body 20.
1. Consists of screws 22 and the like for attaching these rubber bodies 20 and reinforcing bodies 21 to the landing sill 10.

In this embodiment, when the car 2 goes up and down, the engaging body 13 of the landing door 12 is inserted into the notch 1 of the closing body 14.
5, the protruding body 8 of the car door 7 passes outside both end surfaces of the closing piece 19. For this reason,
Car 2 and landing 9 side do not collide. When the car 2 lands on the landing 9, the protruding body 8 of the car door 7 engages with the engaging body 13 of the landing door 12, and the car door 7 and the landing door are connected via these protruding bodies 8 and engaging body 13. 12 are interlocked to perform opening and closing operations, and the closing piece 19 is fitted into the notch 15 of the closing body 14. This eliminates the need for complicated mechanisms.
A gap G formed between a car sill 4 and a landing sill 10 when the car 2 lands on the floor can be closed over the entire length.

In this embodiment, the closing piece 19 is made of a flexible rubber body 20 having an L-shaped cross section, but other materials may be used instead of the rubber body 20 as long as it closes the gap G. , for example, may be constituted by a brush or the like.

Further, for example, the width of the closing piece 19 is set to be approximately the same as the width of the notch 15 on the lowest floor, and the movement of the car 2 is set on the middle floor and the top floor. Taking this into consideration, the width is set to be slightly narrower than the width of the above-mentioned closing piece 19.

<Effects of the invention> Since the present invention is constructed as described above, the gap formed between the car sill and the landing sill when the car lands on the floor can be reduced over the entire length without requiring any complicated mechanism such as a drive device or a control device. It can be blocked for a long time.
Therefore, accidents such as small items falling into the hoistway can be prevented without incurring a large amount of expense, and the fear caused by passengers getting on and off the car from looking at the lower part of the hoistway through the gap can be prevented. There is an effect that it can be done.
