Description

[Detailed description of the invention] This invention relates to an elevator door device.

In the elevator door device, when the car lands on the landing, the engaging body provided on the car door and the retainer provided on the landing door engage with each other, allowing the car door and the landing door to open and close together. It is common to do so.

In addition, the engaging body and the engaging element are usually arranged at positions corresponding to the width of the entrance and exit, so that when the car passes through the landing,
In order to prevent the members of both the car and the landing from colliding with each other, a gap of about 3 cm is usually formed between the entrances and exits of the two.

Therefore, there is a risk that the casters of the wheelchair for the physically handicapped person may fall into the gap between the two, and in this case, there is a problem that the elevator becomes unable to operate.

The present invention solves the above-mentioned drawbacks, and provides an elevator door device in which a car door and a landing door are engaged to open and close, and the gap between the car and landing entrance can be reduced. That is.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

In the figure, 1 is the elevator car, 2 is the entrance/exit of this, and 3
1 is a car door consisting of a sliding door that opens and closes the entrance/exit 2; 4 is a landing; 5 is an entrance of this; 6 is a landing door that is a sliding door that opens and closes the entrance 5; 8 is a drive lever of the drive device 7, and 9 is a car responsive device having an operating range that proportionally reduces the opening/closing stroke of the car door 3; 9 is a car responsive device; This is an engaging body mounted at a position away from the engaging end of the car door 3 of the device 8, and is formed from a member having a recess 9a for retention.

Reference numeral 10 denotes a door pocket of the entrance/exit 2, and numeral 11 denotes a landing response device which is constructed in the same manner as the car response device 8 and operates in the same manner, and is provided in the landing 4 and engaged with the door 6 of the landing.

Reference numeral 12 denotes an engaging element made of a protrusion mounted at a position away from the engaging end of the landing door 6 of the landing response device 11, and is arranged at a position to engage with the recess 9a of the engaging body 9.

In addition, G1 is formed between the width of the entrances and exits 2 and 5 and the front part.
, a gap G2 formed between the landings 4 is a gap formed between the heel 1 of the corresponding portion of the door pocket 10 and the landings 4, and is wider than the gap G1.

That is, when the car door 3 and the landing area 6 are fully opened, the engaging body 9 and the engaging element 12 are located at the positions shown by solid lines in FIGS. 1 to 3, that is, within the projection plane of the gap G2. Ru.

When the car 1 passes through the landing 4, the engaging body 9 moves without contacting the device on the landing 4 side.

Furthermore, when the car 1 lands on the landing 4, the driving device 7 is energized and the door 3 of the car opens. The door is opened.

Then, when the car door 3 and the landing door 6 are fully opened, the engaging body 9,
The engaging member 12 moves to the position shown by the chain line in FIGS. 1 to 3, that is, to a position closer to the entrance 2 than the fully open edge of the car door 3 or the like.

In this way, since the engaging body 9 and the like are not arranged at the position corresponding to the gap G1, the width of the gap G1 can be made as narrow as possible.
For example, it can be set to 1 degree per meter.

Therefore, problems caused by the wide moat of the gap G1 can be prevented.

Furthermore, when the car door 3, etc. is fully opened, the engaging body 9, etc. is placed closer to the doorway 2 than the edge of the fully opened car door 3 on the door opening side, so there is no need to particularly extend the width of the door pocket 10. Entrances 2 and 5 that are sufficiently wide for the elevator hoistway frontage dimensions
can be provided.

As explained above, the present invention provides a response device having an operating range that is proportionally reduced in the opening/closing stroke of a car door and a landing door. It is arranged in the position corresponding to the door pocket regardless of whether the doorway is fully closed or fully open, so that the distance between the car and the landing can be reduced in the part corresponding to the doorway width without particularly extending the width of the door pocket. .

This realizes an elevator door device that is safe for wheelchairs and can provide a sufficiently wide entrance/exit width with respect to the hoistway frontage.
