Telescoping pole with quick length adjustment

Abstract

A pole assembly comprising upper and lower, hollow, telescoping rods. An externally threaded member extends from a fixed attachment at the top end of the upper rod through a nut mounted within the top end of the lower rod. The nut is divided into two half-nuts which are radially movable into and out of threaded engagement with the threaded member. A third rod, slidingly surrounding the lower rod, may be pushed up to cause a pair of tapered teeth at its upper end to engage the half-nuts and move them out of engagement with the threaded member to permit free, relative, linear, axial movement of the upper and lower rods for fast adjustment of the overall length of the assembly. A pair of coil springs in recesses in the half-nuts urge the latter into a nesting fit in a conical inner wall of a bushing, wherein the half-nuts are threadedly engaged with the threaded member to permit fine adjustments of pole length by relative rotation of the upper and lower rods.
