ABSTRACT:
A foldable walker (10) includes a first pair of opposed legs (14,16) and a second pair of opposed legs (13,15). A housing (25) is positioned between the first pair of legs (14,16). The housing (25) carries a lock/release mechanism (35) that includes a depressible button (36). The button (36) is connected to levers (45,47) such that when the button (36) is depressed, the levers (45,47) rotate to translate rods (51,53), respectively. When the rods (51,53) are so moved, pawls (68) connected to the rods (51,53) are rotated out of their normal engagement with bosses (60) carried by the first pair of legs (14,16). The first pair of legs (14,16) may then be rotated with respect to the housing (25) so that the second pair of legs (13,15) are positioned adjacent to each other and to the housing (25). The button (36) will remain depressed until the first pair of legs (14,16) are again locked by the engagement of the pawls (68) with the bosses (60) so as to provide a visual indication that the first of pair legs (14,16) are unlocked.
