Abstract: A mono-fork assembly for a front wheel of a wheelchair. The assembly includes a mono-fork member, an axle, and a retaining member. The mono-fork member has a single tine with a threaded aperture formed therein. The front wheel is rotatable on the axle. The axle has a distal end and a threaded proximal end. The proximal end is configured to be threaded into the threaded aperture of the tine and may be permanently bonded therein. A retaining member is coupled to the distal end of the axle to retain the front wheel on the distal end as the front wheel rotates about the axle. The mono-fork member may include a collar portion aligned along a steering axis for rotation thereabout. The mono-fork assembly may include a bumper configured to extend circumferentially about the collar portion within a circumferential groove formed in the collar portion.

Abstract: A caster mount assembly for a front caster of a wheelchair. The assembly includes a first rotatable body having a first plurality of non-uniformly spaced apart apertures and a second rotatable body having a second plurality of non-uniformly spaced apart apertures. The first and second rotatable bodies may be rotated relative to one another along a common axis of rotation to align a selected one of the first apertures with a selected one of the second apertures. The first rotatable body is non-rotatably coupled to the second rotatable body by a first coupler after the selected first aperture and second aperture have been aligned. A bearing fork assembly is non-rotatably coupled to the second rotatable body for rotation therewith. The second rotatable body may be rotated to orient an upright pivot pin of the bearing fork assembly substantially perpendicular to a support surface.

Abstract: A rear wheel mounting assembly for a wheelchair having a frame with upper and lower longitudinal members vertically spaced from one another and disposed along the same side of the frame. The rear wheel mounting assembly includes an elongated upright member with a plurality of spaced apart recesses arranged longitudinally along an inward face. The elongated upright member includes a clamp disposed at each of its ends. One of the clamps is clamped to the upper longitudinal frame member and the other to the lower longitudinal frame member. The rear wheel mounting assembly includes a camber clamping assembly having an aperture for receiving and retaining an axle of a rear wheel and a removable clamp having a clamping surface engaged with a portion of the elongated upright member. The clamping surface comprises a projection received within one of the recesses of the elongated upright member.
