The crutch is made in two sections, one of which slides within the other, telescopically. A pin which is attached to the inside of the outer tube, located near the bottom thereof, and which slides within spaced, downwardly inverted "L"-shaped grooves running longitudinally on the face of the inner tube, thus locking the two tube sections together when a downward pressure is applied to the top of the crutch. The crutch is also provided with an under arm padded support at its top, a rubber pad at its bottom end, an arm support where required, and an adjustable handle for holding the crutch with the hand.</p> |
