Abstract
1382038 Invalid walking aid ROYALTY DESIGNS CORP 18 May 1973 [26 July 1972] 23737/73 Heading A6M [Also in Division F2] An invalid walking aid comprises frame means 10, two pairs of legs constituted by a front legs 14, 18 and a rear legs 16, 20 each of adjustable length, means coupling together the front leg and rear leg of each pair such that relative shortening of one leg simultaneously effects relative lengthening of the other and locking means disposed on the frame and actuable by the user to lock said front and rear legs of each pair at any desired length, release of the locking means enabling adjustment of the relative lengths of the front and rear lengths. In the embodiment shown legs 14, 16 and 18, 20 have pistons at their inner ends (Fig. 4, not shown) and telescopically slide within respective U-shaped frame members 22, 24. The latter are filled with hydraulic fluid, suitable seals being provided to prevent leakage and each has a valve 52, 54 to control or prevent movement of fluid in the members 22, 24. With the valves open, downward pressure on the front (or rear) of the frame causes the front (or rear) legs to shorten and the corresponding rear (or front) legs to lengthen by fluid passing from one side of the valve to the other. With the valve in its closed or locked position fluid cannot pass from one side to the other and the legs remain fixed in position. The device is of particular use in ascending or descending stairs.
