Abstract: There is provided a foldable walker apparatus with a wheel fork and a frame portion having a first end facing the wheel fork, a first bore extending from the first end towards a second end opposite thereof, an exterior disposed between the first end of the frame portion and the second end of the frame portion, and a second bore disposed between the first end of the frame portion and the second end of the frame portion. The second bore extends from the exterior of the frame portion to the first bore in a direction generally perpendicular to the first bore. A shaft couples with the first bore and includes a recess facing the second bore. A bearing outer race couples to the wheel fork and a bearing inner race couples to the shaft. A securing member extends through the second bore and engages with the recess of the shaft.

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.

Abstract: The present invention relates to a bath seat. The bath seat has a top and a pair of centrally disposed and spaced-apart drainage holes in communication with the top. The top of the seat includes a channel extending between the drainage holes. The channel has an enlarged first end, an enlarged second end and a connecting portion connecting the ends of the channel together. Fluid entering into the channel is directed to the drainage holes and thereby drains from the seat.

Abstract: The present invention relates to, in combination, a foldable walker and a collapsible basket. The walker includes a pair of spaced-apart, operatively interconnected frame members, each having an upper end for placing one's hand and a lower end. The walker has ground-engaging wheels rotatably mounted to the lower end of the frame members. The walker has means for bringing together the frame members for folding the walker. The collapsible basket includes a pair of spaced-apart end members. Each end member has a rigid peripheral portion and is connectable with a respective one of the frame members. The collapsible basket includes a basket member. The basket member is made of flexible fabric. The basket member extends between and is supported by the rigid peripheral portions of the end members. The end members are moveable towards each other, the basket member thereby folding to collapse the basket when folding the walker.

Abstract: The present invention relates to a foldable walker apparatus that includes a pair of upright, spaced-apart elongate members. Each elongate member has an upper end for placing one's hands and a lower end spaced-apart from the upper end. The apparatus has a first pair of ground-engaging wheels rotatably mounted to the elongate members at the lower ends. The apparatus has a pair of support members that are spaced-apart and arc--shaped. The support members align with and extend from the elongate members to distal ends of the support members. The support members have apexes extending towards the upper end of the elongate members. The apparatus includes a second pair of ground--engaging wheels operatively connecting 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.

Abstract: The present invention relates to a wheel mounting assembly for a walker apparatus. The assembly has a pivotable wheel fork and a frame portion. A shaft is coupled to a first one of the wheel fork and the frame portion and is rotatably connected to a second one of the wheel fork and the frame portion. A bearing is interposed between the second one of the wheel fork and the frame portion and the shaft. The assembly has an alignment member with a first portion shaped to extend around and abut with the shaft. The alignment member has a resilient second portion configured to slidably engage with the second one of the wheel fork and the frame portion. The second portion of the alignment member is spaced-apart from the bearing. The alignment member thereby rotatably aligns and further supports pivoting of the wheel fork about the shaft.

Abstract: The present invention relates to a walker apparatus having a means for engaging a brake pad mechanism and a brake pad assembly with a brake housing to partially cover one of the apparatus' wheels. The brake pad assembly includes a brake pad mechanism having a spring-biased brake pad lever pivotally mounted to the brake housing. The brake pad lever is connected at a first end to the means for actuating the brake pad mechanism and has a slot at a second end. A brake pad is slidably insertable within the slot. The brake pad mechanism includes a means for connecting the brake pad within the slot and for adjusting the position of the brake pad relative to the wheel. The brake housing extends around the brake pad mechanism, including the means for connecting and adjusting, to the outer periphery of the wheel for fully protecting the brake pad mechanism.
