Abstract
Abstract A lock assembly for a bicycle quick release mechanism comprises: a shaft member having a threaded bore at one end, for connection to the threaded end of the actuating shaft of the quick release mechanism, and spaced from the shaft member one end a transverse bore providing a shoulder facing the actuating shaft; and a housing adapted for connection to the bicycle wheel fork, the housing having a bore for receiving the shaft member and transverse bore therein and the housing having a lock pin adapted for reciprocation to engage the shoulder in one position and a lock adapted to lock the pin in the shoulder engaging position; whereby the wheel cannot be removed from the bicycle, even with the quick release mechanism in a released position, until the lock assembly is unlocked.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
200 words
A lock assembly for a bicycle wheel quick release mechanism having a shaft extending therethrough transversely of the wheel axle, said shaft adapted, when turned in one direction, to release the wheel for mounting or removal on the fork of a bicycle and, when turned in the other direction to secure said wheel on a bicycle wheel fork, characterized in that the lock assembly comprises: a shaft extension adapted at one end for connection to said shaft and having a shoulder spaced from and facing said one end; and a housing adapted for connection to a bicycle wheel fork and adapted to receive said shoulder of said shaft extension, said housing comprising two parts, a first part having a bore for removeably receiving said shaft extension with said shaft extension connected to a shaft and having a lock pin mounted therein selectively moveable to engage and disengage said shoulder and having a lock connected to said lock pin adapted to lock said pin in a shoulder engaging position, and a second part adapted for connection to said first part, defining with said first part a through bore between said first and second parts for receiving said bicycle wheel fork therein.
Claim 2
Dependent Claim
200 words
A lock assembly for a bicycle wheel quick release mechanism having a shaft extending therethrough transversely of the wheel axle, said shaft adapted, when turned in one direction, to release the wheel for mounting or removal on the fork of a bicycle and, when turned in the other direction to secure said wheel on a bicycle wheel fork, characterized in that the lock assembly comprises: a shaft extension adapted at one end for connection to said shaft and having a shoulder spaced from and facing said one end; and a housing adapted for connection to a bicycle wheel fork and adapted to receive said shoulder of said shaft extension, said housing comprising two parts, a first part having a bore for removeably receiving said shaft extension with said shaft extension connected to a shaft and having a lock pin mounted therein selectively moveable to engage and disengage said shoulder and having a lock connected to said lock pin adapted to lock said pin in a shoulder engaging position, and a second part adapted for connection to said first part, defining with said first part a through bore between said first and second parts for receiving said bicycle wheel fork therein.
Claim 3
Dependent Claim
44 words
The lock assembly claimed in claim 1 further characterized in that said lock and said lock pin are connected and are reciprocable together in said housing, said pin extending into said shaft extension receiving bore in one position and removed therefrom in another position.
Claim 4
Dependent Claim
54 words
The lock assembly claimed in claim 2 further characterized in that said shaft extension comprises a shaft member extending into said shaft extension receiving bore in said housing, a bore extends transversely of said shaft member for receiving said lock pin therein and said shoulder is defined by a surface of said transverse bore.
Claim 5
Dependent Claim
33 words
The lock assembly claimed in claim 3 further characterized in that said shaft extension at said one end comprises a threaded bore to receive a threaded end of said shaft for connection thereto.
Claim 6
Dependent Claim
145 words
In a bicycle having a wheel quick release mechanism for securing a wheel to a fork of the bicycle, said mechanism comprising a shaft for securing and releasing said wheel when the shaft is turned in one direction or the other, a lock assembly for said wheel characterized in that: a shaft member extends from said shaft, said member having a transverse bore therein defining a shoulder facing said shaft; and a housing connected to said fork having a bore into which said shaft member and said shoulder removeably extend and a lock pin connected to a lock reciprocable together within said housing, said lock pin engaging said shoulder in one position and said lock adapted to lock said lock pin in said one position and said lock pin disengaged from said shoulder in another position permitting removal of said shaft member from said bore.
Claim 7
Dependent Claim
145 words
In a bicycle having a wheel quick release mechanism for securing a wheel to a fork of the bicycle, said mechanism comprising a shaft for securing and releasing said wheel when the shaft is turned in one direction or the other, a lock assembly for said wheel characterized in that: a shaft member extends from said shaft, said member having a transverse bore therein defining a shoulder facing said shaft; and a housing connected to said fork having a bore into which said shaft member and said shoulder removeably extend and a lock pin connected to a lock reciprocable together within said housing, said lock pin engaging said shoulder in one position and said lock adapted to lock said lock pin in said one position and said lock pin disengaged from said shoulder in another position permitting removal of said shaft member from said bore.
