Abstract
A wheelchair (100) includes a chassis (101) defining a seat (102), a backrest (103), one or more armrests (104,105), and an undercarriage (106). One or more front caster wheels (118,119) are coupled to, and selectively detachable from, the undercarriage. One or more rear wheel assemblies (120,121) each include a rear wheel (125), an axle (127), and a mounting post (129) extending distally from the axle at a substantially orthogonal angle relative to the axle. One or more quick release devices (130,131) couple each mounting post of each rear wheel assembly to the undercarriage such that the each the one or more rear wheel assemblies is selectively detachable from the undercarriage.
Claims20
A wheelchair, comprising:
- a chassis defining a seat, a backrest, one or more armrests, and an undercarriage;
- one or more front caster wheels coupled to, and selectively detachable from, the undercarriage;
- one or more rear wheel assemblies, each rear wheel assembly comprising a rear wheel, an axle, and a mounting post extending distally from the axle at a substantially orthogonal angle relative to the axle;
- and
- one or more quick release devices;
- each mounting post of each rear wheel assembly coupled to the undercarriage by a quick release device such that the each the one or more rear wheel assemblies is selectively detachable from the undercarriage.
A wheelchair, comprising:
- a chassis defining a seat, a backrest, one or more arm rests, and an undercarriage, the chassis defining a first major dimension that is substantially parallel to a plane defined by the seat and a second major dimension that is substantially orthogonal to the plane;
- and
- two rear wheel assemblies, each rear wheel assembly comprising a mounting post extending distally from an axle;
- and
- two quick release devices, each quick release device to couple each mounting post to the undercarriage such that the each rear wheel assemblies is selectively detachable from the undercarriage to reduce the first major dimension and the second major dimension;
- wherein the each quick release device, when coupled to the undercarriage, is to offset the each mounting post from another plane defined by the backrest to extend the second major dimension by at least one inch.
