ELECTROMAGNETIC SAFETY TRIGGER

摘要

The present disclosure relates generally to a selectively operable safety brake including a magnetic brake operably coupled to a rod and disposed adjacent to a metal component, the magnetic brake configured to move between an engaging position and a non-engaging position, said magnetic brake, when in the engaging position contemporaneously with motion of the machine, moving the rod in to thereby move the safety brake from the non-braking state into the braking state, and an electromagnetic component including a retention apparatus, the electromagnetic component configured to move the magnetic brake from the engaging position to the non-engaging position upon receipt of a resetting signal.

主权项

1. A selectively operable braking device for an elevator system including a car and a plurality of guiderails, comprising:
a safety brake disposed on the car and adapted to be wedged against one of the guiderails when moved from a non-braking state into a braking state; a rod operably coupled to the safety brake, the rod configured to move the safety brake between the non-breaking state and braking state; a magnetic brake operably coupled to the rod and disposed adjacent to the guiderail, the magnetic brake configured to move between a rail-engaging position and a rail-non-engaging position, said magnetic brake, when in the rail-engaging position contemporaneously with motion of the car, moving the rod in a direction to thereby move the safety brake from the non-braking state into the braking state; and an electromagnetic component, the electromagnetic component configured to move the magnetic brake from the rail-engaging position to the rail-non-engaging position upon receipt of a resetting signal.
