The extending frame for a tall cupboard has transverse plugs mounted on its outer upright which fit into recesses in the front panel of the cupboard. These are attached to the upright by clips. The clips are mounted on a vertical threaded spindle (43) which cooperates with bevel gears (45, 46), allowing its vertical position to be adjusted. The spindle may be locked in position by a pin (51) on one of the gears (46) which fits into a longitudinal slot (50) in it. |
