ABSTRACT:
For a wheelchair, an improved handrim assembly includes a wheelrim with circumferentially spaced-apart slots formed through the wheelrim and anchor tab members loosely mounted through the slots. The anchor tabs have enlarged heads on the outer side of the rim and narrower neck portions which extend radially inward of the wheelrim. Fasteners mounted through apertures in the anchor tab necks extend transversely from the anchor tabs and are rigidly connected to portions to a handrim. Each of the slots in the wheelrim is longer in the circumferential direction than in the transverse direction, and the neck portions of the anchor tabs are flat-sided to bear against the long sides of the slots, thereby reducing shear stresses on the tab neck portions and the wheelrim.
