  • Patent number: 11866299
    Abstract: An elevator apparatus provided with a safety gear is disclosed which is adapted to prevent the turn-on of a brake state detection switch during power outage even while being operated by an electric actuator. This elevator apparatus includes: a safety gear 5 disposed at a car 1; and an electric actuator 3 for operating the safety gear. The elevator apparatus further includes a brake state detection switch 6 for detecting a brake state of the safety gear. The brake state detection switch is operated by a mechanism 8 which operates the safety gear with an operation of the electric actuator. The brake state detection switch is in an off state for a displacement of the mechanism during interruption of power supply. The brake state detection switch is turned on for the displacement of the mechanism during the brake of the safety gear.
