Embodiment Construction

[0019] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0020] 1-2, an elevator system embodying the present invention is generally designated by the numeral 10. FIG. The elevator system includes a hoistway 12 defined by surrounding structure 14 . An elevator car 16 is located within the hoistway 12 for up and down movement along the hoistway. The first and second elevator sheaves 20, 22 are connected below the elevator car 16 and on opposite sides. The elevator system 10 includes first and second support columns 24 and 26 disposed on one side 28 of the elevator car 16 and generally at opposite sides 30 , 32 of the hoistway 12 . The first and second support columns 24, 26 extend vertically from the bottom or floor 34 of the hoistway 12 to the top of the hoistway. A support element 36 (shown in phantom in FIG. 1 ) is mounted on top of the hoistway 12 and extends in a generally horizontal direction between the first and second support columns 24 , 26 .

Abstract

An elevator system includes a hoistway defined in a surrounding structure, and an elevator car and at least one counterweight disposed in the hoistway. One drive motor locates between the elevator car and the hoistway. The drive motor is disposed in the overhead space and drivingly couples and suspends the elevator car and the counterweight via at least one flat rope or belt.

Description

[0001] The technical field to which the invention belongs [0002] The present invention relates generally to an elevator system, and more particularly to an elevator system including a drive motor located between an elevator car and a hoistway side wall. Background of the Invention [0003] For elevators, significant costs include the construction of the machine room. Such costs include the cost of constructing the machine room, the cost of the components required to support the weight of the machine room and elevator equipment, and the cost of shading adjacent objects from daylight (eg, the Sunshine Law in Japan and elsewhere). [0004] The object of the present invention is to provide a machine room-less elevator system, which avoids the above-mentioned defects existing in the existing elevator system. [0005] Another object of the present invention is to use flat rope technology to reduce the size of the drive motor and pulley so that a conventional drive motor or flat d...
