Abstract
Abstract A locking system for use with a wheeled vehicle such as a bicycle is described. The system is useful either to lockingly secure a wheel to the fork members of a bicycle or to lockingly secure the seat post to the center frame member. The locking member is cylindrical in shape and covers a specially configured nut that replaces the usual lever operated nut used with a spindled axle system.

Claim 6
Dependent Claim
99 words
The locking system of claim 1 wherein the bifurcated portion of the wheeled vehicle is the bifurcated upper end of the center frame member of a bicycle adapted to receive a bicycle seat post, and wherein said bifurcated upper end of said frame member defines a pair of outwardly extending ears, said ears defining coaxially aligned holes, and wherein said shaft means is adapted to be receive through said 10 axially aligned holes, and further wherein said engagement means is formed to at least partially overlay both ears whereby said engagement means is prevented from rotating when so mounted.
Claim 7
Dependent Claim
32 words
The locking system of claim 5 wherein said shaft means includes at least one cylindrical member, said cylindrical member defining an axial bore of a size sufficient to receive said spindle means.
Claim 8
Dependent Claim
45 words
The locking system of claim 6 wherein the cylindrical member includes a first portion having a diameter less than the diameter of the coaxially aligned holes in said ears and a second portion having a diameter greater than the diameter of the coaxially aligned holes.
Claim 9
Dependent Claim
39 words
The locking system of claim 7 wherein said shaft means includes two cylindrical members, where the first portion of each cylindrical member has a length less than one half the thickness of the combined thickness of the extending ears.
Claim 10
Dependent Claim
35 words
The locking system of claim 7 wherein the first portion of said cylindrical member has a length greater than one half the combined system of the extending ears but less than the combined thickness thereof.
Claim 11
Dependent Claim
52 words
The system of claim 1 further including first resilient means positionable about said spindle means between said shaft means and either said lug or said enlarged end whereby with said lug when threadably engaged on said spindle, said lug or said cylindrically shaped lock means is biased away from said shaft means.
Claim 12
Dependent Claim
46 words
The system of claim 10 further including a second resilient means positionable about said spindle means and located adjacent the other of said lug or said enlarged end and said shaft means whereby said lug and said enlarged end are biased away from said shaft means.
