Abstract: A resetting device for resetting an actuator for actuating a safety gear of an elevator includes an actuation spring to be brought into a compressed state by a resetting force, an electric motor for providing the resetting force and a transmission for transmitting the resetting force of the electric motor to the actuation spring. The transmission provides a positive gear ratio.

Abstract: An apparatus for actuating a safety gear of an elevator includes a first stage actuation mechanism; and a second stage actuation mechanism. The second stage actuation mechanism includes a wedge arrangement configured to grip a guiderail associated with the elevator when the first stage actuation mechanism is triggered; a casing including the wedge arrangement and configured for vertical linear movement along the guiderail; and a transmission member coupled to the casing from a first end and to the safety gear from a second end. The apparatus is configured to cause the safety gear to actuate when the first stage actuation mechanism is triggered, the first stage actuation mechanism causing the wedge arrangement of the second stage actuation mechanism to grip the guiderail of the elevator and to decelerate vertical movement of the casing in relation to the guiderail, the deceleration of the casing causing the transmission member to engage the safety gear to the guiderail to stop the elevator.

Abstract: The system comprises a synchronization shaft rotatably supported on an elevator car frame, the synchronization shaft being operatively connected to at least one safety gear, a lever attached to the synchronization shaft, an electromagnet operatively connected to the lever, spring means operatively connected to the synchronization shaft, and resetting means operatively connected to the synchronization shaft. Deactivation of the electromagnet releases the lever allowing the spring means to rotate the synchronization shaft from a first position to a second position in which the safety gear is activated. Activation of the resetting means rotates the synchronization shaft from the second position to the first position in which the safety gear is deactivated and the spring means is brought back to the excited state at the same time.
