LATCH FOR TELESCOPING VACUUM-CLEANER TUBE

摘要

A vacuum-cleaner wand has an inner tube formed with an axially extending row of radially outwardly open recesses, an outer tube, and a latch base part fixed to the outer tube and formed with an elastically deformable web carrying a latching block displaceable radially into and out of the recesses. The base part also is formed with a pair of radially outwardly projecting guide walls forming radially inwardly directed guide edges. A movable latch part fitting over the base part is formed with a pair of radially inwardly projecting guide walls forming radially outwardly directed guide edges sliding on the guide edges of the base part for sliding between axially offset latched and unlatched positions. A radially inwardly projecting actuating bump formed in the movable part bears in the latched position radially inward on the block and holds the block in the inner position.
