Abstract
An elevator system including an elevator car mounted for vertical movement in the hoistway of a building, and a plurality of traveling cables which interconnect the elevator car and a junction box in the hoistway. The plurality of traveling cables are bundled to track as a single cable by a plurality of spaced retainer devices. Each retainer device includes a first portion which is tightly secured to one of the traveling cables, and a second portion which loosely encircles all of the traveling cables.
Claims4
An elevator system, comprising:
- a building having a hoistway,
- an elevator car mounted for vertical movement in the hoistway of said building,
- a plurality of flexible electrical traveling cables connected between said elevator car and a predetermined point of the hoistway,
- said plurality of cables being suspended from said elevator car such that each hangs in the hoistway with a bight which moves with car movement,
- and traveling cable retainer means including a plurality of retainer devices, each of said retainer devices including a flexible strap having a first portion tightly secured to one of said traveling cables, and a second portion disposed about all of the traveling cables in a non-stretched condition to provide a loose containment thereof, said plurality of retainer devices being disposed about said traveling cables at spaced locations such that the traveling cables track as a single cable without restricting relative longitudinal movement between the traveling cables.
