Embodiment Construction

[0020] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings.

[0021] Figure 3 shows a machine room-less elevator system constructed in accordance with the present invention.

[0022] A machine-room-less elevator system is an elevator system without a conventional machine room for the elevator machinery, which machine-room-less elevator system is usually located in the upper space of a shaft through which the elevator car 22 and the counterweight 24 travel. In this shaft, the elevator car 22 can be passed vertically through the pulley 28 of the counterweight 24 and the pulley (not shown) of the elevator mechanism 70 by the main rope or belt 30 held on the pulley of the elevator car 22 11 (these pulleys 11 are attached to the elevator car 22 in a hanging manner). The elevator machinery carries the high loads of the elevator system by means of the main ropes 30 held over its sheaves.

Abstract

There is provided a machineroom-less elevator system with a machine support assembly having at least a pair of support members and a holder for holding an elevator machine, which is supported between and by the pair of support members. Each pair of the support members extends across a hoistway and is separated from each other in a longitudinal direction. Outer ends of the pair of support members are fixed to opposite walls defining the hoistway. The holder generally has a rectangular shape. The machine support assembly further has an auxiliary support member extending in parallel with the pair of support members, and a plurality of connecting bodies connecting the pair of support members to the auxiliary support member and connecting the holder to the auxiliary support member.

Description

technical field [0001] The present invention relates generally to machine roomless elevator systems and more particularly to machine roomless elevator systems having a mechanical support assembly by which the elevator is mechanically supported in a more stable position with low noise, vibration, and torque extremely small. Background technique [0002] Fig. 1 shows an elevator mechanical support assembly of a prior art machine room-less elevator system. The elevator machine 6 is attached to a U-shaped frame formed by members 2a, 4a and 4b, which are fixed to counterweight guide rails 5a and 5b by members 7a to 7d. Rubber pads 3a and 3b are held between the members 7c, 7d and the horizontal plate 2b below the members 7c and 7d to absorb vibrations during the mechanical operation of the elevator. A pair of brackets 1a and 1b for supporting the weight of the members 7a to 7d and the elevator machine 6 are fixed to the counterweight guide rails 5a and 5b. [0003] However, th...
