Title:
エレベータ装置
Document Type and Number:
Japanese Patent JP7445791
Kind Code:
B2
Abstract:
Disclosed is an elevator apparatus equipped with an emergency stop device that makes it possible to improve the reliability of movement while being electrically actuated. This elevator apparatus comprises a drive mechanism that drives an emergency stop device, and an electric actuator that actuates the drive mechanism. The electric actuator (10) is equipped with: a movable member (34); an electromagnet (35) that faces the movable member; a mechanism part (36, 37, 40 to 42) that linearly moves the electromagnet; and an operation lever (11) that is connected to the drive mechanism (12 to 16, 19) and rotatably connected to the connection bracket (38) of the movable member. In a standby state, the operation lever and the drive mechanism are restrained by the attraction of the movable member to the electromagnet, and during the operation of the emergency stop device, when the electromagnet is demagnetized and the operation lever and the drive mechanism are unrestrained, the drive mechanism is actuated and the operation lever is rotated to move the movable member. The electric actuator is equipped with a member (101) that suppresses the tilt of the moved movable member.
