BOTH-WAY MOVABLE BODY DRIVING MECHANISM AND ELEVATOR DEVICE USING THE SAME

WIPO Patent Application WO/2002/064482

A1

An elevator device comprises a car (1) disposed for lifting and lowering in a shaft, a counterweight (2) to be lifted and lowered according to the lifting and lowering of the car (1), and a lifting and lowering driving mechanism for lifting and lowering the car (1). The lifting and lowering driving mechanism comprises a sheave (42) disposed in the shaft, a rope (3) disposed in a path via the sheave (42), and a driving device (5) engaging the rope (3). The driving device (5) comprises a belt transmission mechanism attached to the rope (3) and orbiting along the installation path of the rope (3), a pressing mechanism for pressing the belt surface of the belt transmission mechanism against the rope (3), and a driving motor for driving the belt transmission mechanism. Thereby, it becomes possible to lift and lower the car without using a traction sheave, and the weight-reduction of the car can be attained.
