A damper unit for an elevator for reducing vertical vibrations of an elevator car of the elevator during a standstill includes a stamp-like acting element that acts on an end-face guide surface of a guide rail. The acting element is spaced from the guide rail in an idle position and can be connected slip-free to the guide rail by an eccentric drive in an active position. Force transmitting elements containing a shock damper for damping the motions of the elevator car during a standstill of the car adjoin the acting element.

A damping device for damping movement of a parked car in an elevator system includes a base plate and at least one damping assembly connected to the base plate. The damping assembly includes a flange extending from the base plate, a support member arranged at a distance from the flange, and at least one damping mechanism having a first end connected to the flange and a second end connected to the support member. The at least one damping assembly restricts movement of the support member toward the flange.

The invention relates to a support apparatus for an elevator car. The support apparatus comprises a support block for attaching to a sidewall of an elevator hoistway, the support block having an oblique surface. The support apparatus also comprises a sliding plate for mounting to the elevator car. The sliding plate is movable between an extended position and a retracted position. The sliding plate has an oblique surface facing the oblique surface of the support block when the sliding plate is in the extended position. The sliding plate is slideable over the oblique surface of the support block when being moved from the extended position to the retracted position. The support apparatus also comprises an actuator shaft attached to the sliding plate and an actuator configured to move the sliding plate using the actuator shaft from the extended position to the retracted position. The actuator is attachable to the elevator car.

An elevator damping unit for reducing vertical oscillations of an elevator car when at a standstill, has brake shoe retainers provided with brake shoes. The brake shoe retainers are connected to a common electric motor via a toothed gear mechanism. The toothed gear mechanism has a central driving gearwheel, which adjoins a drive shaft of the motor, and eccentric gearwheels, which are each assigned to one of the brake shoes and are in operative connection with the driving gearwheel. The brake shoes are supported resiliently on the respective brake shoe retainers in each case via two helical compression springs.
