  • Procedure and apparatus for triggering the safety gear of an elevator
    Patent number: 5630483
    Abstract: In this overspeed governor, an overspeed condition causes, by way of coupling elements (15,15'), a brake (5) comprised in the overspeed governor to engage a rope pulley (3) which, due to friction, brakes the rope driving the rope pulley itself and thus triggers the safety gear of the elevator. In the invention, the rotation of at least one coupling element (15,15') provided in the overspeed governor and rotating with it is braked by a frictional force which is applied to a braking point (31,32) on the coupling element (15,15'). The combined effect of the braking action and the rotation of the overspeed governor turns the coupling element (15,15') into a position in which the brake (5) is activated so as to engage the rope pulley (3).
