Abstract:
A collapsible Wheeled Walker with two side frames and two height adjustable upper body supports. The apparatus includes a plurality of wheel direction locks each coupled to a wheel and adapted to lock the wheel in fixed moving direction or to release the wheel to turn freely. The apparatus may include a seat that is slidably attached to the two side frames and is movable between a front position for walking inside the frames and a rear position sitting. The apparatus may be converted to a transport chair by locking front wheel and releasing the rear wheels, and sliding the movable seat to the rear position. It may include an X-folder that facilitates collapsing the Walker to a small footprint. It may also include two forearm gutters as part of the upper body supports that give the user an upright walking posture for health benefits.

Claim (Index 11):
A method to convert a collapsible wheeled walker apparatus to a transport chair apparatus, the wheeled walker apparatus having a frame including a first side frame and a second side frame defining a polygonal footprint on a walking surface, a plurality of wheel assemblies coupled to the frame for supporting the frame above the walking surface and disposed at the vertices of the polygonal footprint, each wheel assembly including a wheel and a wheel fork having a lock depression, the wheeled walker having a first upper body support and a second upper body support each independently coupled to and disposed at an adjustable height above the respective side frame, the adjustable height of each upper body support adjusted by a height adjusting mechanism, each upper body support coupled to a respective handle for gripping by a respective user hand, a plurality of wheel direction locks each coupled to the frame above a respective wheel assembly, each wheel direction lock having a wheel direction lock element adapted for insertion into the lock depression in the respective wheel fork to lock the respective wheel to a fixed moving direction, wherein when not in locked position the respective wheel assembly may freely turn around a respective shaft connecting the wheel fork to the frame above, the wheeled walker having a seat apparatus including a seat member having a first side edge and a second side edge disposed at an approximately horizontal position, each side edge being moveably engaged with the respective side frame such that the seat apparatus may be moved between an anterior walking position to provide an ample walking space inside the wheeled walker for the user and a posterior sitting position, the method comprising:\n setting each front wheel direction lock to allow the respective wheel to move in a fixed direction; setting each rear wheel direction lock to allow the respective wheel to freely turn; and sliding the seat apparatus to the posterior sitting position to accept a seated user.
