VERTICAL TRACK DEVICE FOR RAISING AND LOWERING FIXTURES THEREON

摘要

A vertical track with a slidable carriage assembly for raising and lowering selectable objects, that may easily retrofit existing poles with existing electrical wiring, is disclosed. The vertical track has a T-shaped slot, which extends the majority of the length of the face of the track. The carriage fits within the slot and the carriage extends at least partially beyond the slot to attach a selectable object. The T-shaped slot also encloses a looped cable with a pulley system and an electrical transfer bus. One side of the looped cable is attached to the bottom of the carriage. The other side of the cable travels over a pulley mounted in the upper portion of the slot, down along an interior edge of the slot over a lower pulley and returns to the top of the carriage. A detachable power source rotationally drives the lower pulley.
