ABSTRACT:
A telescoping pole crank assembly having a tubular pole crank which movably mounts an extension pole for setting the overall length of the pole crank assembly. The extension pole is held in its adjusted position by a locking collar structure including a collar collet fixed to the pole crank and an outside collar rotatably mounted thereon for controlling the engagement of clamping fingers on the collar collet with the extension pole. The extension pole is rotationally interlocked with the pole crank by a series of elongated ribs formed on the extension pole which interfit with slots between clamping fingers of the collar collet. The components are held in assembled relation by rivets which interconnect the collar collet to the pole crank and with the rivets being held in position by the outside collar which is rotatably threaded on the collar collet and a coacting structure on the outside collar and the collar collet limit the separating movement of one with respect to the other after initial assembly.
