Document Type and Number:
WIPO Patent Application WO/2003/043921
Kind Code:
A1
Abstract:
An elevator in which a supporting member (10) of a hoisting machine (9) disposed close to the top of a hoistway (1) and inside the hoistway (1) by the upper end of a rail (6) for a counterweight which is erected in the hoistway to guide the elevating&sol lowering of the counterweight (8). The rail (6) for the counterweight is connected to a rail (3) for a car by disposing a connector (17) in the vertical direction between rail brackets (4) for fixing the rail (3) for the car to a fixing member (5) of the hoistway (1). When the rail (6) displaces perpendicularly to the axis, the displacement is transmitted to the rail (3) for the car via the connector (17) for support. Thus, the rail (6) for the counterbalance is not buckled, the strength thereof can be close to the value required for the guide function of the counterweight (8), the size of the rail (6) for the counterweight can be reduced, and the manufacturing cost of the elevator is reduced.
