Patent number: 4800910Abstract: A walker having a unique leg support system in which the walker's two stationary front legs are interchangeable at the user's discretion with two wheeled front legs, both types of legs being height adjustable relative to the walker's framework. The wheeled front legs are connectable to the walker's frame so the wheels can be oriented on either the outboard or the inboard of the walker's front leg. Each wheeled front leg includes a wheel axle and a pivot axle connected thereto, the pivot axle being pivotably connected to a front leg so the front leg can roll along a support surface, e.g., ground, on the wheel when the wheel is pivoted to a first position and so the front leg's foot can stand stationary on the support surface when the wheel is pivoted to a second position.Type: GrantFiled: February 24, 1987Date of Patent: January 31, 1989Assignee: The Kendall CompanyInventor: Paul B.

Patent number: 4621804Abstract: A therapeutic walker has features which permit its use by persons with varying degrees of disability and is capable of adaptation to be used in different ways as the level of disability diminishes. A walker frame extends substantially around three sides of the region occupied by person using the walker and a removable closure bar is attached across the frame on its open side. An elongated crotch-cradling panel of flexible material is removably attached between the closure bar and the frame on the opposite side of the walker. The person using the walker straddles the crotch-cradling panel which is adjustable in length for persons of different sizes.

Patent number: 4576392Abstract: A ratchet-type catch assembly is disclosed for attachment as a slide connection between a scissors frame and an object supported by the frame. While one leg of the scissors frame is fixed to the object in a hinge-type, nonsliding manner and the other in sliding manner, the assembly forms part of the latter, providing a series of locking catches at successively varying angles of the scissors frame, and the discrete graduated heights of the object. The pawl and ratchet stops are oriented to permit vertical elongation of the frame by the application of upward force to the object, while preventing collapse. The catch is opened by release of the pawl, permitting complete collapse of the frame to a flattened configuration.Type: GrantFiled: December 7, 1984Date of Patent: March 18, 1986Assignee: Gerber Products CompanyInventor: Robert L.

Patent number: 4251105Abstract: A mobility aid comprises a four-legged walking frame characterized by the front legs of the frame having ground-engaging wheels with axes movable in unison in the direction of the lengths of the legs, by one-way wheel-driving means responsive to upwards movement of said wheel axes to cause forward rotational motion of the wheels, and by resilient means acting to urge said wheel axes downwardly of the front legs.In the freestanding condition of the frame, the resilient means lift the front of the frame so that when the frame is pressed down by the user bearing down on the frame, the wheels are caused to rotate in the sense to cause forward movement of the aid, the rear legs dragging as a result. A repeated bearing down action, easily accomplished even by the severely handicapped, thus results in easily controllable forward motion of the aid.Type: GrantFiled: July 3, 1979Date of Patent: February 17, 1981Inventor: Alfred W. Barker
