Claim 1
Independent Claim 284 words
A bicycle including a front fork having a pair of depending legs, means defining an open ended slot in each of said legs extending upwardly from lower ends thereof, means defining an elongated aperture of rectangular configuration in each of said legs adjacent to and above the slots formed therein and extending lengthwise of the legs, a pair of retaining clips each including an enlarged head of substantially T-shaped configuration, a substantially planar body portion extending at substantially right angles to said T-shaped head, and a neck portion extending normally from said body portion and interconnecting said enlarged head and said body portion, said enlarged heads being received through said apertures and engaging edge portions of said legs defining said slots to retain said heads therein, said body portions overlying the slots of the legs with which they are associated, said T-shaped heads being of greater lengths than the widths of said apertures and of lesser lengths than the lengths of said apertures, whereby said clips must be rotated approximately 90* from their positions with said body portions overlying said apertures to disengage said T-shaped heads from said apertures, means defining elongated openings through said body portions extending coextensively with a portion of said slots in said legs, a front wheel having an axle, outer ends of said axle being threaded and received within said slots in said legs and said openings in said cliPs and thereby preventing rotation of said clips with respect to said legs and consequent disengagement of said heads from said apertures, and nuts threaded onto said threaded outer ends of said axles and securing said axle within both said slots in said legs and said openings in said clips.
