elevator

Abstract

The invention provides an elevator capable of easy release even when a passenger is being pulled in. The elevator is characterized by having a car for passengers, a car door equipped on the car, an engagement device equipped on the car door, a hall door arranged at a hall and engaged with the car door via the engagement device to move, a self-closing device that applies a self-closing force to thehall door in a closing direction, a door opening / closing drive device for driving the car door, and a door opening safety device for detecting an abnormality in a door opening operation of the car, wherein, in a case where the door opening safety device detects an abnormality, the door opening / closing drive device generates a drive force in the door opening direction.

Description

technical field [0001] The present invention relates to an elevator equipped with a door safety device for detecting pull-in and the like. Background technique [0002] Patent Document 1 exists as background art in this technical field. Patent Document 1 describes the following content: In an elevator entrance and exit device having a plurality of door bodies which are respectively openable and closable at the entrance and exit of the elevator, the entrance and exit device of the elevator is provided with: a plurality of door bodies each independently driving. The door opening and closing mechanism of the motor; the control mechanism for controlling the action of the motor; and the detection mechanism for detecting the foreign objects drawn in when the plurality of doors are opened, so that the detection mechanism detects a foreign object drawn in. The opening action of the side door body stops. [0003] prior art literature [0004] Patent Document 1: Japanese Patent Lai...

AI Technical Summary

Problems solved by technology

[0005] However, in the elevator apparatus described in Patent Document 1, the door is stopped in the state of being pulled in during the pull-in detection, so it is difficult to pull out the door from the clamped state.

In addition, the example of cutting off the power supply of the door machine is also described, but usually a self-closing device composed of a spring or a weight is provided to apply a force to the door in the closing direction, and the door is reversed by the closing force of the door closer. When closing the door, even if the door is reversed, the hand pulled in cannot be released immediately, and there is a situation where it is not easy to avoid danger
