Abstract
Abstract A quick release locking assembly including an integral lock and protected opposite end formed in combination with a quick release apparatus for securing a wheel to a bicycle frame in a theftproof manner. The hand-operated lever of the quick release is prevented from rotating by a locking pin which engages a bore in the quick release assembly to prevent rotation thereof, while the adjustable nuts on the opposite threaded end are prevented from being removed by the end cap housing which encases and protects the nuts in a manner such that neither the end cap housing or the nuts can be removed when the assembly is mounted on a bicycle. When secured, the quick release lever cannot be rotated, nor can the nuts securing the opposite end be accessed, offering complete security to the object secured.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
211 words
A bicycle wheel quick release assembly for securing the wheel to the fork of a bicycle frame comprising: a central mounting shaft having a first end threaded to receive locking nuts and an end cap and a second end formed of a cylindrical shaft extension having a transverse bore therein; cylindrical housing means including a first chamber having an opening to receive said cylindrical shaft extension for reciprocal movement therein, and a second chamber having an opening to receive a locking mechanism including a locking pin; drive means, including a rotatable lever and eccentric drive shaft, said eccentric drive shaft having a transverse bore therein adapted to receive said locking pin, said eccentric drive shaft being rotatably mounted within said shaft extension transverse bore for longitudinally moving said central mounting shaft and said shaft extension relative to said bicycle frame fork for loosening and tightening said assembly relative to said fork; said locking pin being in communication with said eccentric drive shaft whereby, in use, said locking pin is selectively moveable to engage and disengage said drive shaft transverse bore of said eccentric drive shaft to prevent and permit rotational movement thereof respectively, in turn preventing and permitting longitudinal movement of said central mounting shaft relative to said bicycle frame fork.
Claim 2
Dependent Claim
211 words
A bicycle wheel quick release assembly for securing the wheel to the fork of a bicycle frame comprising: a central mounting shaft having a first end threaded to receive locking nuts and an end cap and a second end formed of a cylindrical shaft extension having a transverse bore therein; cylindrical housing means including a first chamber having an opening to receive said cylindrical shaft extension for reciprocal movement therein, and a second chamber having an opening to receive a locking mechanism including a locking pin; drive means, including a rotatable lever and eccentric drive shaft, said eccentric drive shaft having a transverse bore therein adapted to receive said locking pin, said eccentric drive shaft being rotatably mounted within said shaft extension transverse bore for longitudinally moving said central mounting shaft and said shaft extension relative to said bicycle frame fork for loosening and tightening said assembly relative to said fork; said locking pin being in communication with said eccentric drive shaft whereby, in use, said locking pin is selectively moveable to engage and disengage said drive shaft transverse bore of said eccentric drive shaft to prevent and permit rotational movement thereof respectively, in turn preventing and permitting longitudinal movement of said central mounting shaft relative to said bicycle frame fork.
Claim 3
Dependent Claim
28 words
The bicycle wheel quick release assembly of claim 1 wherein said first chamber and said second chamber include an opening therebetween to accommodate said selectively moveable locking pin.
Claim 4
Dependent Claim
29 words
The bicycle wheel quick release assembly of claim 1 wherein said cylindrical housing means is further characterized by having its longitudinal axis in line with said central mounting shaft.
Claim 5
Dependent Claim
