Includes Gear On Support Mating With Stationary Rack Patents (Class 187/352)
  • Patent number: 10662029
    Abstract: An overspeed governor including a governor sheave, a permanent magnet rotor coupled to the governor sheave, a stator arranged to interact with the permanent magnet rotor, a safety gear for braking movement of an elevator car and a safety rope fixed to the safety gear and arranged to run via the governor sheave. The stator includes a winding adapted to exert, when energized, to the permanent magnet rotor a braking force that brakes movement of the permanent magnet rotor and, consequently, movement of the governor sheave and the safety rope, thereby activating the safety gear.

  • Patent number: 10479649
    Abstract: An over-speed detection device (OSDD) and over-speed governor (OSG) for a stairlift is tripped by flyweights which displace from a rotational axis of the OSDD/OSG when subjected to an over-speed. The outward displacement of the flyweights is converted into an axial displacement to effect triggering of the OSG. This ensures that the tripping speed is independent of the angle if inclination of the stairlift rail. The OSDD/OSG may be mounted so that it takes its drive from a convex surface of the rail in negative transition bends. This ensures that the speed of the OSDD/OSG is maintained close to the tripping speed even when the carriage is slowed to traverse the negative transition bend.

  • Patent number: 10435273
    Abstract: A braking system and method for an apparatus or vehicle moved along a pathway by an apparatus drive mechanism, for halting the movement of the apparatus or vehicle in the event that the drive mechanism loses power or malfunctions. A conveyance system includes a pathway, an moving apparatus moving along the pathway, the apparatus drive mechanism, a brake rail along the pathway having along one edge a multiplicity of regularly spaced teeth with gaps between successive teeth, and a brake device mounted securely to the apparatus. The brake device includes a rotatably driven rotor having outer helical threads for running the gaps in the brake rail with successive turns of the driven rotor without touching the teeth.

  • Patent number: 9388018
    Abstract: The invention concerns an arrangement in the supply of rope to the speed limiter of an elevator. The arrangement comprises at least a braking device for braking the rope being supplied to the speed limiter. As new rope is being fed to the speed limiter, the new rope has been fitted to run via the braking device and under a diverting pulley in the lower part of the elevator shaft and passed further from the diverting pulley over an upper speed limiter pulley to act on the safety gear of the elevator.

  • Patent number: 8875845
    Abstract: A lift car securing arrangement includes a restraining arrangement having a restraint that is supported by the lift car arranged such that it can be placed into and removed from restraining interaction with an extended stationary interaction element arranged to extend along the vertical pathway of the lift car, and which restraint when placed into restraining interaction locks the lift car to the stationary interaction element, a power-interruption device that can be placed into and removed from a power-interrupting position whereby the power to a driving motor unit that is part of the lift is interrupted when the power-interruption device is placed arranged in its power-interrupting position, in which the power-interruption device is so arranged at the restraining arrangement that the said power-interruption device is located in its power-interrupting position when the restraint has been set into restraining interaction with the extended stationary interaction element.

  • Publication number: 20020070082
    Abstract: A safety brake for the load receiving portion of an elevator includes a fixing device that is displaceable relative to the load receiving portion in the direction of the guide rail between two abutments fastened to the load receiving portion. The unlocking of the safety brake after a braking process is achieved by moving the load receiving portion with the assistance of the elevator drive unit oppositely to the direction of movement before the braking process, so that one of the abutments fastened to the load receiving portion strikes the fixing device to unlock it from the guide rail.
