ABSTRACT:
The sports wheelchair includes a one-piece, welded tubular frame assembly (A). A pair of rear wheels (30) are horizontally and adjustably positionable in a rear wheel mounting plate (34). The mounting plate has a plurality of slots (36, 38, 40) and a plurality of alternating ridges (44) and valleys (46) which mesh with like ridges (50) and valleys (52) on an axle receiving assembly (42). A pair of front wheels (80) are mounted with a front wheel mounting assembly (82) to be selectively positioned in any one of three vertical positions (FIGS. 6, 8, and 9). The front wheels are further mountable on the inside or the outside of a lower horizontal frame portion (10) and in any one of a plurality of positions fore and aft along the horizontal frame portion. The user is supported by a fabric seat (170) which is laced to upper horizontal frame portions (12) and to a back structure (150). The back structure is connected with the frame structure by a hinge (152) such that the back is selectively foldable for easier transportation. A foot supporting structure (180) is selectively positionable in any one of a plurality of positions. A roller (202) is positioned on the foot support to inhibit the chair from tipping forward. A shield (210) inhibits the fingers of the user or others from engaging spokes of the rear wheel and causing injury.
