ABSTRACT:
A walker with wheels that are retracted upon the application of a force of predetermined magnitude to permit a user to move the walker when he or she partially leans on the walker while providing a solid anchored support if he or she leans with more weight exceeding a predetermined magnitude. The walker includes a structural elongated assembly with a handle and forearm cuff at one end. The other end is rigidly mounted to two base assemblies that are kept at a parallel and spaced apart relationship with respect to each other. The base assemblies have a bottom surface. Retractable wheels are mounted to the base assemblies. The wheels are spring biased to protrude beyond the bottom surface so that they support the walker when at rest and as long as the user does not apply a force that exceeds a predetermined magnitude.
