Send a signal to the worker above.

While adjusting the position with respect to the hanger case 11 so that the worker on the car room 3 who has received this signal accurately faces the detection unit 8 already attached to the scale 14 at the factory before shipping. By fixing the plywood 9, the assembly of the detection device including the engagement plate 9 and the detection unit 8 is completed.

As described above, the position detection device for an elevator according to the above-mentioned proposal requires two workers for the assembling work, which is complicated, and there is a problem that the assembling work cost increases.

The present invention has been made in view of the current state of the elevator position detecting device of this type as described above, and an object thereof is to provide an elevator position detecting device that can be easily assembled by one worker. To provide.

<Means for Solving Problems> In order to achieve the above object, the present invention includes a detection unit fixed to a car side of an elevator and an engagement plate fixed to a hoistway wall side, and At the time of landing of the car, the elevator that detects the landing position where the sill of the landing door and the sill of the car door coincide with each other in accordance with the detection portion and the engagement plate facing each other. In the position detection device, the engagement plate provided at the end of the hall door sill in the direction of movement of the hall door, and the engagement plate protruding at the end of the direction of movement of the car door in the sill of the car, facing the engagement plate. It is configured to include the detection unit provided at the position.

<Operation> In the present invention, the detection device for detecting the landing position where the sill of the landing door and the sill of the car door coincide with each other when the car lands on the floor. It is composed of an engagement plate fixed to the road wall side.

Then, the engagement plate is attached to the sill end portion of the hall door, and the detection unit is attached to a position facing the engagement plate at the sill end portion of the car door.

Therefore, one worker confirms that the sill of the landing door and the sill of the car door coincide with each other at the landing position, so that the detecting portion and the engaging plate face each other at this position accurately. It can be installed by adjusting the positions of the sill end of the car door and the sill end of the landing door, respectively.

<Example> Hereinafter, an example of the present invention will be described in detail with reference to FIGS. 1 and 2.
