RETRACTABLE ROLLER SUPPORT FOR USE WITH FLEXIBLE ROLLING SUPPORT FOR CONDUCTORS OR CONDUITS

摘要

RETRACTABLE ROLLER SUPPORT FOR USE WITH FLEXIBLE ROLLING SUPPORT FOR CONDUCTORS OR CONDUITS The effective movement range of a rolling support such as a flexible chain linkage for electrical conductors and/or fluid conduits is materially increased by the provision of one or more retractable roller supports for the elevated cantilevered section of the rolling support upstream from its lower anchored end. The retractable roller support allows the rolling loop portion of the rolling support to pass through the retractable roller support in either direction. The weight of the rolling support is utilized to bias the retractable roller support toward its active supporting position.
