ABSTRACT:
A mobility aid (FIG.1) design for providing stabilized mobility support by the practical use of a two sided vertically supported rigid frame comprising front and rear bilaterally double support members (12), (12a), (13), (13a), (15), and (15a), and not limited to but preferably of aluminum construction to include a plurality of upper and lower substantially identical bilaterally horizontal and vertical tubular main frame members (17), (18), (19), (20), (22), (27), (28), and (29), supported on a plurality of sufficiently sized wheels (26), and (30), attached to the underside of the main frame (26), and (30), with predetermined spacing. Base members (22), (28), and (29), are sufficiently elevated-providing for unhindered foot movement during mobilization. A guide wheel assembly (23), (25), (25b), (26), and (26a), is vertically attached at a contiguously anterior junction surface of the two sided main frame assembly (20), and (23), thereby providing selective directional steering. Hand brake controls (16), secure by clamps to riser connectors (15), activate brakes (31).
