Abstract: There is a provided a collapsible walker. The walker includes a pair of spaced-apart, arc-shaped support members. Each support member has a proximal end, a distal end and an apex spaced therebetween. Respective rods extend from the distal ends towards the proximal ends of the support members. A seat extends between and connects to the apexes of the support members. A basket with a pair of spaced-apart ends members operatively connects to and extends between the support members. The end members are positioned adjacent to the distal ends of the support members. Each end member operatively connects to both a respective one of the rods and a respective one of the support members. The walker includes a pair of connection brackets for connecting the end members to the walker. Each connection bracket extends from a respective one of the support members to a respective one of the rods.

Abstract: There is provided a brake pad assembly for a walker apparatus. The walker apparatus has a frame and a wheel pivotally connected to the frame. The assembly includes a brake pad mechanism having a brake pad. The brake pad mechanism is spring-biased to position the brake pad spaced-apart from and adjacent to the wheel. The brake pad mechanism is configured to cause the brake pad to abut the wheel when the brake pad mechanism is actuated. The assembly includes an arch-shaped brake housing. The brake pad mechanism pivotally mounts to the arch-shaped brake housing. The arch-shaped brake housing extends completely over the brake pad mechanism for fully protecting the brake pad mechanism.

Abstract: 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.

Abstract: The present invention relates to a bath seat. The bath seat has a top, a front end, and a back end opposite thereof. The top extends between the front end and the back end of the bath seat. The top includes a centrally disposed channel. The channel includes an enlarged first end, a second end opposite thereof, and a connecting portion connecting the ends of the channel together. The second end of the channel aligns with one of the front end and the back end of the seat. Fluid entering into the channel is directed to the second end of the channel, past said one of the front end and the back end of the seat and thereby drains from the seat.

Abstract: 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.
