Abstract
A support pole for raising and lowering a supported object between a lower position and an elevated position is disclosed. The support pole includes an elongate pole having a top, a bottom, and a channel extending at least partly between the top and bottom. A threaded rod is rotationally mounted within the channel, and is connected to a detachable coupling for engaging a drive tool to rotationally drive the threaded rod. A carriage engages the threaded rod, such that rotation of the rod imparts translational movement upon the carriage through the channel. The carriage includes a mounting bracket for attachment of the supported object thereto. A cable connecting the supported object and an external device or power source has a detachable coupling, and is carried along a pulley at the top of the elongate pole when the carriage is raised and lowered. A return spring is connected to one end of the cable to retract the free end of the cable back to the base of the pole when the supported object is raised into the elevated position. Carriage locks at the top of the pole engage the carriage in the elevated position to prevent vibration of the supported object. A stabilizer frame within th…
