Abstract (en)
[origin: WO2020050768A1] The present invention relates to a mechanism (20) for a safety device for lift car for preventing unintended car movement of the lift car. The mechanism comprise a brake (21) and at least one trigger element (30A,30B) which is coupled to the brake, wherein the at least one trigger element being capable of rotating around a regulator shaft of the safety device, wherein the at least one trigger element being brought into a trigger state by the brake (21) when the mechanism is activated, and in the trigger state, the at least one trigger element (30A,30B is prevented from rotating by the brake (21), wherein the at least one trigger element (30A,30B) is connected to a first drive gear (24) wherein the brake (21) comprises a rotatable brake shaft (23) provided with a second drive gear (26) which is engaged with the first drive gear (24), and the brake comprises a brake arrangement (25) adapted to be engaged with the brake shaft when the mechanism is in an active state for braking the rotation of the brake shaft, the first and second drive gear and the at least one trigger element. The present invention also relates to safety device for a lift car and a safety arrangement for a lift system for preventing unintended car movement of the lift car.
