Abstract (en)
[origin: US2007007083A1] A progressive safety device for an elevator includes a brake unit and an actuating unit. The brake unit has a first brake shoe with first spring assemblies and a triangular rotatable support with second and third brake shoes. The actuating unit has an electromagnetic actuator with a locking bolt, a guide bolt with a coaxial compression spring and an actuating arm. On actuation, the compression spring moves the actuating arm against a guide rail whereby grooves on the actuating arm create a frictional engagement with the guide rail turning the actuating arm about a swivel bearing and through a follower turning the support. With the turning motion and the engagement of one of the second and third brake shoes with the guide rail, the first brake shoe is guided against the guide rail and generates the necessary braking force on the guide rail.
