Problems solved by technology

[0004] In the above-mentioned prior art, since a pressure-sensitive sensor capable of detecting a small pressing force is provided on the front end member of the elevator door by direct bonding, false detection may occur due to vibration when the elevator door is closed.
In addition, since the pressure sensitive sensor is directly bonded to the front end member, it is inconvenient to replace the sensor when the sensor fails, etc.

Abstract

The invention provides an elevator door device, which is capable of not only preventing error detection, but also executing replacement operation of sensor conveniently. The elevator door device comprises an elevator door and a detection sensor, wherein the elevator door is used for opening and closing the entrance to the elevator cage, and the detection sensor is used for detection of foreign substance clamped in the elevator door. In the elevator door, the detection sensor is clamped in the buffering components capable of being divided, and disposed on the doorstop column of the elevator or door shield portion of at least one elevator door.

Description

technical field [0001] The invention relates to an elevator door device, which uses a pressure-sensitive sensor or the like to detect whether flexible foreign objects such as ropes are caught in the elevator door. Background technique [0002] As a known elevator door device, for example, a solution is disclosed in Patent Document 1. In this solution, an elevator door is installed at the entrance and exit of the elevator car, and a detection device is provided at the front end of the closing direction side of the elevator door. Whether the elevator door is in contact with a person or an object is a pressure-sensitive sensor. When the front end of the elevator door in the closing direction is in contact with a person or an object when the elevator door is closing, the pressure-sensitive sensor can This contact is detected, and the closing motion of the elevator door can be switched from the closing motion to the opening motion on the way. (For example, refer to Patent Docume...
