<p>A locking assembly for telescopically moving tubes, the assembly comprising an outer tube (11), a collar (24) located at one end of outer tube (11), a slider mount on collar (24) that projects substantially radially away from collar (24), a slider (35) engaged on the slider mount so that it is able to slide along the slider mount, abutment means (51, 44) at each end of the slider mount to limit movement of slider (35), an inner tube (10) located within outer tube (11) and through collar (24) for telescopic movement with respect to outer tube (11), and locking means (50) acting between collar (24) and inner tube (10) to hold inner tube (10) with respect to outer tube (11), locking means (50) being operated by slider (35) to both disengage locking means (50) to thereby allow relative movement of inner and outer tubes (10, 11) and to re-engage locking means (50). Applications of the locking assembly include telescopic wands used with vacuum cleaning machines, tripod legs, or any other form of adjustable structure or support.</p> |
