Patent ID: 7878094

Claim:
A tool comprising: a working tool portion; and an extendable handle joined with the working tool portion, the extendable handle comprising: a shaft comprising a plurality of circumferential grooves; a tube slidably mounted on the shaft, the tube forming an opening in the wall thereof; an anti-rotation member carried within the opening in the wall of the tube, and having at least a portion thereof received within an axially arranged groove disposed on the shaft, wherein the anti-rotation member is disposed in the opening in the wall of the tube and in the axially arranged groove on the shaft so as to prevent, during application of relative rotational force between the shaft and tube, relative rotation between the shaft and tube; a stop member carried by the shaft wherein the stop member engages the anti-rotation member to prevent the tube from separating from the shaft when the tube is moved axially relative to the shaft to a maximum distance, wherein one end of the stop member is received within an aperture formed in the shaft and the other end of the stop member extends radially outward from the surface of the axially arranged groove; and a lock device comprising a collar slidably mounted on the tube, wherein the collar is movable from a first position to a second position wherein when the collar is in the first position the tube is prevented from moving axially relative to the shaft by engagement of the lock device with one of the plurality of circumferential grooves, wherein when the collar is in the second position the tube can be moved axially relative to the shaft, and wherein the collar is mounted on the tube such that in each of the first position and the second position the collar covers the opening in the tube to prevent the portion of the anti-rotation member in the axially arranged groove from being removed from the axially arranged groove.
