Embodiment Construction

[0022] The same components in the various drawings are denoted by the same reference numerals. The guide shoe comprises a box-shaped support 2 mounted on the elevator car 1, open on one side. Notches are arranged on the support top surface 14 and the bottom surface 15, and the guide rail 3 is placed in the notches. Inside the bracket 2 there is a middle frame 5 whose shape corresponds to the inner space of the bracket, and the middle frame also has a notch for placing a guide rail.

[0023] The intermediate frame has guide means 4 surrounding the guide rail recesses, which in this embodiment are sliding bearing surfaces against the guide rail 3 . The intermediate frame 5 is spaced apart from the support 2 by a distance both vertically and laterally, in other words, there is no contact between the adjacent surfaces of the support and the intermediate frame in any direction.

[0024] In the vertical direction, the intermediate frame 5 is connected with the support 2 from the u...

Abstract

Elevator guide shoe for guiding an elevator car along guide rails in an elevator shaft, said guide shoe comprising a supporting frame (2) attached to the elevator car (1) and guides (4) resting against a guide rail (3). According to the invention, the guide shoe comprises an intermediate frame (5), to which the guides (4) are attached. In addition, the supporting frame (2) and the intermediate frame (5) are provided with permanent magnet bars (6a, 6b, 7a, 7b, 8a, 8b) arranged to maintain a horizontal distance between the supporting frame and the intermediate frame. Moreover, the guide shoe comprises vertical suspension (9) between the supporting frame and the intermediate frame to damp the propagation of sound in the structures.

Description

technical field [0001] The invention relates to an elevator guide shoe. Background technique [0002] Guide shoes are used in the elevator car to guide the elevator car along the guide rails in the elevator shaft. The guide shoes are fitted with sliding or rolling bearings which rest against the rails. However, the structure-borne noise generated by the movement of the elevator car provided with such supports on the guide rails is transmitted to the inside of the elevator car, causing discomfort to the elevator passengers. [0003] In the prior art, several methods are used to eliminate these problems. In Japanese Patent Specification 7196273, to solve these problems, servo-controlled magnetic coils are used to levitate the elevator car. This is a difficult solution due to the use of expensive control engineering systems. [0004] The elevator proposed in Japanese Patent Specification 55-25589 uses permanent magnets installed in the elevator shaft and permanent magnets o...
