摘要： A brake device for braking a traveling body movable along a guide rail in a movement direction includes a holder mounting a brake element that has a brake surface directed toward the guide rail, the brake element being movable relative to the holder between a free-running position and a braking position. A pretensioning element is activated to exert a force that moves the brake element toward the braking position. A release element holds the pretensioning element in a holding state and is activated into a released state to reconfigure the pretensioning element from a deactivated configuration into the activated configuration. A pressing element in an actuated state generates a force on the brake element in a direction toward the guide rail to enable a reset of the brake device.

摘要： A safety brake includes a first brake element, a first guide element, and an actuating element. The first brake element is mounted in a displaceable manner in a linear bearing on the first guide element. The first guide element can be moved between a rest position and a braking initial position. The actuating element is designed to move the first guide element from the rest position into the braking initial position, more particularly to activate the safety brake. The first brake element can carry out a braking movement from the braking initial position into a braking position. The braking movement returns the first guide element to the rest position. The first guide element is guided on a first parallelogram guide.

摘要： An overspeed governor assembly for an elevator system, an elevator safety system, and an elevator system. The overspeed governor assembly comprises an overspeed governor, a linkage provided to enable the overspeed governor to associate with a safety device of the elevator, when an elevator car overspeed is occurring, to trigger the safety device to perform safety measures, and at least one torsion spring coupled between a sheave and a centrifugal mechanism in the overspeed governor for providing a pre-set load, and the centrifugal force formed by the centrifugal mechanism when the elevator car overspeed is occurring, is greater than the pre-set load, for triggering the safety device via the linkage.

摘要： An actuation mechanism for an elevator safety gear comprises an engagement element, at least two permanent magnets and at least one electric coil. The engagement element is movable between an engaged position in which it engages with the guide member of the elevator system and a disengaged position in which it does not engage with the guide member of the elevator system. The at least two permanent magnets are arranged in a configuration generating a repulsive force (FR) between the at least two permanent magnets and urging the engagement element towards the engaged position. The at least one electric coil is configured for generating an electromagnetic force urging the engagement element towards the disengaged position and/or for holding the engagement element in the disengaged position, when an electric current is flowing through the at least one electric coil.

摘要： The invention relates to a method and a device for safety braking for an elevator (1) having an upright guide rail (3). The safety brake device (4) comprises a housing (5) having braking elements (6, 7) which are arranged on both sides of the guide rail (3) and are movable along the guide rail (3), a safety restraint (8) on both sides between the housing (5) and the braking elements (6, 7), and a clampable and lockable actuating device (9) for the braking elements (6, 7), which unlocks and unclamps in response to a triggering event and brings the braking elements (6, 7) into braking engagement with the guide rail (3). The actuating device (9), when it is unclamped, develops a feed force (F) and feed movement directed transversely to the longitudinal axis (15) of the guide rail (3), which brings the braking elements (6, 7) on both sides into engagement with the guide rail (3) from a laterally distanced initial position, wherein the braking elements (6, 7) are entrained by frictional contact on the guide rail (3) and enter the safety restraint (8), and wherein the actuating device (9) is moved back into its initial position and clamped and locked by the braking elements (6, 7) located in the safety restraint (8).

摘要： A device for a friction force provider for an emergency safety actuator for an elevator is disclosed. The friction force provider may include a housing having a first end and an opposing second end, where the first end may define an opening. The friction force provider may further include a primary magnet positioned within the housing and configured to move between an armed position and a working position. The primary magnet may be configured to create a force on a rail of an elevator system in the working position and be held within the housing in the armed position.
