US Patent 11980827 Telescopic item and mechanism therefor

A telescopic mechanism including hollow telescopic blade segments with a threaded spindle having spindle threads within the telescopic blade segments. Nuts are configured to correspond and interface with the spindle, and a power mechanism is configured to spin the spindle. Each of the nuts respectively interfaces at the proximal portion of each of the hollow blade segments and the nuts have nut threads corresponding to the spindle threads. The nut threads allow back and forth movement over the spindle threads when the spindle is rotated; however, the nut threads will slide over the spindle threads if the distal telescopic blade segment is pushed above a given threshold force.
