Bicycle fork end construction

Claim 2

In a bicycle the combination comprising a front wheel fork having a pair of spaced depending legs; a pair of generally downwardly facing receivers on the lower region of said legs; a wheel hub axle extending between and having its opposite ends received in respective receivers; releasable fastener means on said axle ends for releasably securing the latter in said downwardly facing receivers; a retaining portion depending from each downwardly facing receiver; and a generally upwardly facing receiver depending from each retaining portion in facing spaced relation with an associated downwardly facing receiver to form a passageway for intentional insertion and removal of said wheel hub axle from said receivers, said wheel hub axle normally being positioned and retained by said fastener means within said downwardly facing receivers generally on one side of said passageway, said upwardly facing receivers being arranged to receive said wheel hub axle generally on the other side of said passageway during riding over rough terrain on accidental loosening of said fastener means to thereby prevent said wheel hub axle from unintended exit from said receivers through said passageway.

Claim 3

The combination according to claim 1, said downwardly facing receivers facing substantially vertically downwardly.

Claim 4

The combination according to claim 1, said upwardly facing receivers facing substantially vertically upwardly.

Claim 5

The combination according to claim 1, each associated pair of said upwardly and downwardly facing receivers and said retaining portions combining to provide a generally C-shaped configuration.

Claim 6

The combination according to claim 1, said fastener means comprising threaded members.

Claim 7

The combination according to claim 1, said fastener means comprising quick release securement means.

Claim 8

In a bicycle, the combination comprising a front wheel fork having a pair of spaced depending legs, a pair of downwardly facing receivers on the lower region of said legs, a wheel hub axle extending between and having its opposite ends received in respective receivers, releasable fastener means on said axle ends for releasably securing the latter in said receivers, a rearward retaining portion depending from the rear of each receiver to retain said axle ends against unintended exit from said receivers on accidental loosening of said fastener means during forward riding, and a lower retaining portion extending forwardly from each of said rearward retaining portions below the adjacent receiver; upwardly facing receivers carried by said lower retaining portions in respective facing spaced relation with said downwardly facing receivers for receiving and retaining said axle ends against unintended exit from said receivers on accidental loss of said fastening means during riding over rough terrain, said lower retaining portions being spaced below said receivers sufficiently to provide therebetween a forwardly opening axle exit passageway for intentional exit therethrough of said axle, each associated pair of said upwardly and downwardly facing receivers and said rearward retaining portions combining to provide a generally C-shaped configuration.

Claim 9

In a bicycle, the combination comprising a front wheel fork having a pair of spaced depending legs, a pair of downwardly facing receivers on the lower region of said legs, a wheel hub axle extending between and having its opposite ends received in respective receivers, releasable fastener means on said axle ends for releasably securing the latter in said receivers, a rearward retaining portion depending from the rear of each receiver to retain said axle ends against unintended exit from said receivers on accidental loosening of said fastener means during forward riding, and a lower retaining portion extending forwardly from each of said rearward retaining portions below the adjacent receiver; upwardly facing receivers carried by said lower retaining portions in respective facing spaced relation with said downwardly facing receivers for receiving and retaining said axle ends against unintended exit from said receivers on accidental loss of said fastening means during riding over rough terrain, said lower retaining portions being spaced below said receivers sufficiently to provide therebetween a forwardly opening axle exit passageway for intentional exit therethrough of said axle, each associated pair of said upwardly and downwardly facing receivers and said rearward retaining portions combining to provide a generally C-shaped configuration.

Claim 10

In a bicycle, the combination comprising a front wheel fork having a pair of spaced depending legs, a pair of downwardly facing receivers on the lower region of said legs, a wheel hub axle extending between and having its opposite ends received in respective receivers, releasable fastener means on said axle ends for releasably securing the latter in said receivers, a rearward retaining portion depending from the rear of each receiver to retain said axle ends against unintended exit from said receivers on accidental loosening of said fastener means during forward riding, and a lower retaining portion extending forwardly from each of said rearward retaining portions below the adjacent receiver; upwardly facing receivers carried by said lower retaining portions in respective facing spaced relation with said downwardly facing receivers for receiving and retaining said axle ends against unintended exit from said receivers on accidental loss of said fastening means during riding over rough terrain, said lower retaining portions being spaced below said receivers sufficiently to provide therebetween a forwardly opening axle exit passageway for intentional exit therethrough of said axle, each associated pair of said upwardly and downwardly facing receivers and said rearward retaining portions being defined by an integral generally C-shaped unit.

Claim 11

In a bicycle, the combination comprising a front wheel fork having a pair of spaced depending legs, a pair of downwardly facing receivers on the lower region of said legs, a wheel hub axle extending between and having its opposite ends received in respective receivers, releasable fastener means on said axle ends for releasably securing the latter in said receivers, a rearward retaining portion depending from the rear of each receiver to retain said axle ends against unintended exit from said receivers on accidental loosening of said fastener means during forward riding, and a lower retaining portion extending forwardly from each of said rearward retaining portions below the adjacent receiver; upwardly facing receivers carried by said lower retaining portions in respective facing spaced relation with said downwardly facing receivers for receiving and retaining said axle ends against unintended exit from said receivers on accidental loss of said fastening means during riding over rough terrain, said lower retaining portions being spaced below said receivers sufficiently to provide therebetween a forwardly opening axle exit passageway for intentional exit therethrough of said axle, each associated pair of said upwardly and downwardly facing receivers and said rearward retaining portions being defined by an integral generally C-shaped unit.

Claim 12

The combination according to claim 8, said integral units each being generally flat and in laterally spaced parallelism with each other.
