  • Patent number: 4790553
    Abstract: A lightweight wheelchair (10) including a front frame (27), footrest assembly (33), and mounting means (34,48) for mounting the footrest assembly (33) to the frame (27) for pivotal movement between a position in front of the chair and a position beside the chair is disclosed. The footrest assembly (33) is mounted to a front frame member (27) of the chair by a pivotal joint (34) and is further supported by a support bracket (48) which engages a side of the front frame member (27) below the pivotal joint (34). Mounted to the bracket (48) and front frame member (27) are cooperating subassemblies (56,57) which latch the footrest assembly (33) in a position in front of the chair and simultaneously bind or cam-down the inner end (49) of the bracket (48) against the side of the vertical front frame member (27).

  • Patent number: 4687218
    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.
