Title:
ELEVATOR
Document Type and Number:
WIPO Patent Application WO/2011/099278
Kind Code:
A1
Abstract:
Disclosed is an elevator which can solve the problems originating in the lengthways rotational force generated by a wire-suspended cage, by means of a simple structure. The elevator raises and lowers a wire-suspended cage in a raising and lowering path. The elevator has a suspension device, and a wire connection unit. The suspension device is provided at the top part of the raising and lowering path, and synchronises and winds up at least three wires. The wire connection unit is provided in the cage and there are the same number of wire connection units as there are wires. The plurality of wires and the plurality of wire connection units are connected in a one-to-one manner. The cage, suspended by the plurality of wires, freely deforms so that the plurality of wire
connection units independently change position in the up/down direction. The movement range of the centre of gravity of the cage, in the horizontal plane of projection, is restricted to the range contained within a polygon, the peak point of which is the vertical load bearing point of the plurality of wires.
