A safety brake system () for use in a conveyance system. The safety brake system () includes a guide rail () and a conveyance component moveable along the guide rail (). The safety brake system () includes a safety brake (), a linkage mechanism () and an actuator () for the safety brake (). The safety brake () is moveable between a non-braking position where the safety brake () is not in engagement with the guide rail () and a braking position where the safety brake () is engaged with the guide rail (). The actuator () is configured to be mounted to the conveyance component and positioned between first and second ferromagnetic components. The actuator includes an array of magnetic components including a first magnetic component adjacent to and arranged between two second magnetic components.

A protector () for an elevator car () includes a protective panel () and at least one magnet () mounted to the protective panel (). The magnet () is configured to be attracted to an internal wall () of a passenger compartment () of an elevator car () so as to retain the protective panel () against the internal wall (). The magnet () may be retained against a support () of the protector () by a retainer assembly (). The protector () may further comprise an electrical device which comprises a lighting device () configured to emit light into the passenger compartment () of the elevator car ().

A frictionless safety brake actuator, for use in an elevator system, includes at least two stators; a magnet array positioned between the stators; a linkage attached to the magnet array; and a biasing arrangement. The linkage is actuatable to move a safety brake into frictional engagement with an elevator guide rail. The magnet array is moveable between a first position in which the linkage is actuated and a second position in which the linkage is not actuated. The biasing arrangement is arranged to bias the magnet array towards the first position. The magnet array includes a first magnet set and a second magnet set which comprise at least one magnet each and at least three magnets in total. The magnet(s) of the first magnet set is/are arranged alternately with the magnet(s) of the second magnet set in a stack.

Frictionless safety brake actuator

An elevator car or counterweight, comprising a frame, the frame including an upright structure in which a safety brake is mounted so as to allow for lateral movement of the safety brake relative to the upright structure; at least a first vertically or obliquely extending cantilever spring; wherein a first end of the first cantilever spring is mounted to the upright structure; and wherein the first cantilever spring is arranged such that a point remote from the first end provides a biasing force to the safety brake when the safety brake moves away from a default position. As the safety brake is mounted to allow for lateral movement relative to the frame, the safety brake essentially floats relative to the car or counterweight.
