摘要： A foldable walker apparatus includes a pair of spaced-apart inner frame members of two parts each hinged together, with a pair of link members diagonally extending therebetween. Each link has a bend extending upwardly and outwardly. The walker has support members that are arc-shaped with a seat extending between their apexes. A collapsible basket is provided with two end members each having a rigid peripheral portion connecting the frame members and a basket member of flexible fabric extending therebetween. A self-adjusting brake rod is provided with a gripping member spring-biased to remain free of the brake rod until the gripping member is operatively actuated to engage and thereby actuate the brake rod. A brake housing fully extends around a brake pad mechanism, including a means for connecting and adjusting the corresponding brake pad, to at least the outer periphery of one of the wheels for fully protecting the brake pad mechanism.

摘要： There is provided a wheel mounting assembly having a wheel fork. The fork includes an interior and an inwardly extending protrusion disposed within the interior. The assembly includes a rotatable member operatively connected to the fork and disposed within the interior of the fork. The protrusion abuts and positions in place the rotatable member. The assembly includes a shaft. The rotatable member rotatably connects the shaft to the wheel fork. The assembly includes a retaining member connected to the shaft. The retaining member is configured to abut the protrusion of the fork and thus inhibit dislodgement of the rotatable member from the fork when the shaft is tilted relative to the fork.

摘要： There is provided a walker apparatus having a brake, a braking handle, a brake wire, a brake rod, and a brake rod assembly. A gripping member connects to the brake wire. The gripping member includes a plate having a first end, a second end and an aperture near the second end. The plate connects to the brake wire near the first end and the plate slidably receives the brake rod through the aperture near the second end. The gripping member includes a clamp that engages the brake wire via a set screw. The gripping member is spring-biased to remain free of the brake rod in a non-actuated mode. When the braking handle actuates the brake wire, the plate tilts with the first end elevating relative to the second end, thereby causing the plate to engage with and abut the brake rod for thereby actuating the brake rod to brake.

摘要： There is provided a walker apparatus having a pair of upright, spaced-apart elongate members. Each elongate member includes an upper end for placing one's hands and a lower end spaced-apart from the upper end. A first pair of ground-engaging wheels are rotatably mounted to the elongate members at the lower ends. The apparatus includes a pair of support members that are spaced-apart and arc-shaped. The support members align respectively with and extend from the elongate members to distal ends of the support members. The support members have apexes extending towards the upper ends of the elongate members. A second pair of ground-engaging wheels operatively connect to the distal ends of the support members. The apparatus includes a seat for resting connecting to the apexes of the support members, the support members thereby supporting the seat.

摘要： There is provided a walker apparatus having a frame, a wheel pivotally connected to the frame, and a brake pad assembly. The assembly has a brake housing configured to partially cover the wheel. The assembly has a brake pad mechanism including a brake pad lever pivotally mounted to the housing. The brake pad lever is actuated via a first end and has a second end spaced-apart therefrom. The brake pad mechanism has a brake pad connected to the brake pad lever adjacent to the second end of the brake pad lever. The brake pad lever is spring-biased to position the brake pad spaced-apart from and adjacent to the wheel. The brake pad lever is configured to cause the brake pad to abut the wheel when the lever is actuated. The brake housing extends about the brake pad mechanism for fully protecting the brake pad mechanism.
