Embodiment Construction

[0018] Embodiments of the present invention will be described below with reference to the drawings. Fig. 1 is a side sectional view of the whole elevator apparatus in the first embodiment of the present invention. In the hoistway of the elevator, a pair of left and right guide rails in a T-shaped cross-sectional shape are arranged in the vertical direction, and the elevator car 43 moves up and down along the guide rails 1 . Wherein, since the guide rail 1 will have height differences and twists during installation, and the height differences and twists act on the elevator car 43 to cause forced displacement. Generally, in order to prevent the vibration generated by this forced displacement from being transmitted to the elevator car 43 , an anti-vibration rubber block 42 is provided between the elevator car 43 and the car frame 7 . And, the car frame 7 is configured such that guides 41a, 41b are provided at its upper and lower parts, respectively, so that the elevator car 43 c...

Abstract

To provide an elevator, the elevator having an inexpensive guide device simple in constitution. The elevator has a pair of guide rails (1) arranged in a hoistway and a riding car (43) lifting along these guide rails, and controls a pressing force by one actuator (33) to guide rails of two guide rollers (2a, 2b) arranged on both sides by sandwiching the guide rails (1). Coil springs (4a, 4b) for pressing the rollers (2a, 2b) to the guide rails are fixed to rods (5a, 5b) connected to both ends of a movable body (35) movably horizontally. Compressive forces of the coil springs (4a, 4b) can be changed according to the vibration of the riding car (43) and the state of an unbalanced load by the control force of the actuator (33).

Description

technical field [0001] The present invention relates to an elevator that ascends and descends along guide rails, and the invention is particularly suitable for achieving good passenger comfort of the elevator. Background technique [0002] Since the elevator ascends and descends along the guide rails provided in the vertical direction, guiding devices are respectively installed on the upper and lower parts of the elevator car. The guiding device generally consists of rollers in contact with the guide rail, rods supporting the rollers with shafts, and springs that press the rollers against the guide rails with a certain force. In order to improve the passenger comfort of the elevator car, for example, a method is disclosed in the content described in Patent Document 1. In this method, the inclination of the elevator car is detected to change the inclination applied by the rollers on the guide rail. pressing force. In this invention, there is provided a mechanism for driving...
