Abstract: A disclosed walker is a three sided framework allowing quick connect/disconnect to the frame of a conventional standard wheelchair. The walker is formed with a front and two side assemblies pivotally linked to the front assembly. When the walker is not connected to a wheelchair, the side assemblies and front assemblies pivot and collapse into a “z” pattern forming a flat, compact package. For connection to a wheelchair, the sides assemblies unfold perpendicularly to the front assembly, and are locked into place by a horizontal crossbar. U-shaped securing clips located at the rear ends of the walker's side assemblies, drop over and straddle horizontal frame members of the wheelchair tightly grasping the wheelchair's frame members. The stability of the walker/wheelchair combination is enhanced by outward bends of the front vertical sections of the walker which terminate in swivel caster supports.
