Embodiment Construction

[0032] figure 1An elevator, denoted as a whole by 1, is shown with a car 2 that can move up and down for transporting people or goods. The elevator car 2 can be moved in the vertical elevator shaft by means of a drive unit via support means, for example in the form of load-bearing ropes or belts (not shown here). The car 2 has a car bottom 24, to which a car side wall 25, indicated by a dashed line, adjoins the car bottom. For guiding the cage, the elevator installation 1 has guide rails 3 extending in the vertical direction z. Sliding guide shoes 20 are arranged on the car 2 , by means of which the car 2 can be guided along the guide rail 3 of the moving car. In this embodiment, the guide shoe 20 is mounted on the bottom 24 of the car. The car 2 can additionally have a further guide shoe 20 in the region of the car ceiling. The guide shoe 20 may be a sliding guide shoe. Alternatively, however, it is also conceivable to use a roller guide shoe as guide shoe 20 .

Abstract

A vibration-damping unit for an elevator to dampen vertical vibrations of a stationary elevator car (2), having at least one roller (5, 6, 7) contacting a guide rail in an active state (3), and can rotate around the rotation axis (R). The rollers (5, 6, 7) are connected to rotary dampers (8, 9, 10) in order to dampen the rotary motion when the car (2) in parking is vibrating vertically.

Description

technical field [0001] The invention relates to a vibration damping unit for an elevator. Background technique [0002] People or goods stepping into or leaving the elevator car cause the car to vibrate undesirably due to the elasticity of the load-bearing mechanism. Such vertical vibrations occur in particular in elevators based on carrying belts as the load-bearing mechanism, which have recently gained increasing popularity. Compared with steel cables, belts have more unfavorable vibration behavior, and vertical vibrations increasingly hinder the comfort experience and safety of passengers. In addition, this problem becomes more acute as the height of the elevator increases. In order to dampen such vibrations, it is known to use a separate damping unit which, for example, exerts a lower braking force on the guide rail than a safety brake or other safety-critical braking devices. [0003] A similar damping unit of this type is known, for example, from EP1424302A1. There...
