Quick release wheel retainer

Claim 2

A quick-release wheel retainer comprising: a bicycle front fork having at least one drop-out including a substantially vertical slot; a hook-shaped member having an open, crook portion being arcuately-shaped and including top and bottom portions forming an arcuate inner periphery extending greater than 180°; means for pivotally connected said top portion of said member to said drop-out at a point directly vertically above said slot such that said member pivots in a plane perpendicular to a central axis of axis of an axle extending through said drop out to a position wherein said crook portion is in registry with said slot to close an open end of said slot retain an axle therein; and said inner periphery being shaped such that said bottom portion curves upwardly toward said top portion, when said member is in registry with said slot, sufficiently to require a slight upward movement of said axle to enable said crook portion to be pivoted out of registry with said slot, whereby gravity acting upon a retained axle against said member urges said member to remain in registry with said slot.

Claim 3

The quick-release wheel retainer of claim 1 further comprising a generally planar tab projecting perpendicular from said hook shape member.

Claim 4

The quick-release wheel retainer of claim 2 wherein said tab further comprises at least two planar portions generally having a V-shape, said first portion of said V being connected to said retainer, and said second portion of said V being adapted to be grasped by a user to facilitate movement of said member between a locked and an unlocked position.

Claim 5

The retainer of claim 1 wherein said arcuate top portion includes a flange attached to said drop-out by said connecting means; and said inner periphery being shaped such that a lower tip thereof is spaced from an upper tip thereof a distance less than a diameter of said inner periphery.

Claim 6

The retainer of claim 1 wherein said connecting means includes a rivet extending through said flange and said drop-out at a point substantially vertically above said slot, and a spring washer mounted on said rivet and positioned between said flange and said drop-out.

Claim 7

A quick-release wheel retainer comprising: a bicycle front fork having at least one drop-out including a substantially vertical slot; a hook-shaped member having an open, crook portion being arcuate-shaped and including top and bottom portions forming an arcuate inner periphery extending greater than 180°, said hook-shaped member including an arcuate top portion having a flange, a linear mid portion, and an arcuate bottom portion, said top, mid- and bottom portions forming said inner periphery; means for pivotally connecting said flange of said member to said drop-out at a point directly vertically above said slot such that said member pivots in a plane perpendicular to a central axis of an axle extending through said drop-out to a position wherein said crook portion is in registry with said slot to close an open end of said slot to retain an axle therein; and said inner periphery being shaped such that said bottom portion curves upwardly toward said top portion, when said member is in registry with said slot, sufficiently to require a slight upward movement of said axle to enable said crook portion to be pivot out of registry with said slot, and wherein a lower tip of said inner periphery is spaced from an upper tip thereof a distance less than a diameter of said inner periphery, whereby gravity acting upon a retained axle against said member urges said member to remain in registry with said slot, said connecting means including a rivet extending through said flange and said drop-out and a spring washer mounted on said rivet and positioned between said flange and said drop-out.

Claim 8

A quick-release wheel retainer comprising: a bicycle front fork having at least one drop-out including a substantially vertical slot; a hook-shaped member having an open, crook portion being arcuate-shaped and including top and bottom portions forming an arcuate inner periphery extending greater than 180°, said hook-shaped member including an arcuate top portion having a flange, a linear mid portion, and an arcuate bottom portion, said top, mid- and bottom portions forming said inner periphery; means for pivotally connecting said flange of said member to said drop-out at a point directly vertically above said slot such that said member pivots in a plane perpendicular to a central axis of an axle extending through said drop-out to a position wherein said crook portion is in registry with said slot to close an open end of said slot to retain an axle therein; and said inner periphery being shaped such that said bottom portion curves upwardly toward said top portion, when said member is in registry with said slot, sufficiently to require a slight upward movement of said axle to enable said crook portion to be pivot out of registry with said slot, and wherein a lower tip of said inner periphery is spaced from an upper tip thereof a distance less than a diameter of said inner periphery, whereby gravity acting upon a retained axle against said member urges said member to remain in registry with said slot, said connecting means including a rivet extending through said flange and said drop-out and a spring washer mounted on said rivet and positioned between said flange and said drop-out.
