发明名称 Telescopically adjustable game cue
摘要 A telescopic cue for billiards, pool, snooker and the like includes telescopically engaged central and butt sections permitting infinite adjustment of cue length between two end positions and a lock for securing the central and butt sections by frictional engagement at any selected cue length. The frictional engagement is provided by a member on one of the butt and central sections arranged for radial expansion or contraction to engage frictionally the other of the butt and central sections to prevent relative axial movement of the butt and central sections. The member may comprise a collet disposed between two relatively movable abutments which are urged towards one another on relative rotation of the butt and central sections or two parts of the same section to expand or contract the member to provide the aforesaid frictional engagement.
