Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
170 words
In combination with an object, said object having at least a wheel to facilitate moving of said object, a wheel lock assembly comprising: an aperture structure formed within the hub portion of said wheel, the longitudinal axis of said aperture structure being substantially parallel to the axis of said wheel; a housing located adjacent said wheel, said housing being formed of a movable element and a fixed element, said movable element being pivotally attached to said fixed element; A biasing means located between said movable element and said fixed element; a pin connected to said movable element, said pin being capable of cooperating with said aperture structure to thereby prevent rotation of said wheel, said biasing means tending to move said pin into cooperation with said aperture structure, said pin being movable out of disassociation of said aperture structure, the direction of said pin movement being substantially parallel to the wheel axis; and manually operated actuating means to facilitate movement of said movable element with respect to said fixed element.
Claim 2
Dependent Claim
170 words
In combination with an object, said object having at least a wheel to facilitate moving of said object, a wheel lock assembly comprising: an aperture structure formed within the hub portion of said wheel, the longitudinal axis of said aperture structure being substantially parallel to the axis of said wheel; a housing located adjacent said wheel, said housing being formed of a movable element and a fixed element, said movable element being pivotally attached to said fixed element; A biasing means located between said movable element and said fixed element; a pin connected to said movable element, said pin being capable of cooperating with said aperture structure to thereby prevent rotation of said wheel, said biasing means tending to move said pin into cooperation with said aperture structure, said pin being movable out of disassociation of said aperture structure, the direction of said pin movement being substantially parallel to the wheel axis; and manually operated actuating means to facilitate movement of said movable element with respect to said fixed element.
Claim 3
Dependent Claim
26 words
2 The combination as defined in claim 1 wherein: said pin being capable of a slight amount of pivotal movement with respect to said movable element.
Claim 4
Dependent Claim
178 words
In combination with an object, said object having at least a wheel to facilitate moving of said object, a wheel lock assembly comprising: an aperture structure formed within the hub portion of said wheel; a housing located adjacent said wheel, said housing being formed of a movable element and a fixed element, said movable element being pivotally attached to said fixed element; a biasing means located between said movable element and said fixed element; a pin connected to said movable element, said pin being capable of cooperating with said aperture structure to thereby prevent rotation of said wheel, said biasing means tending to move said pin into cooperation with said aperture structure, said pin being movable out of disassociation of said aperture structure; manually operated actuating means to facilitate movement of said movable element with respect to said fixed element; said pin being capable of a slight amount of pivotal movement with respect to said movable element; and said pin being conducted through said fixed element, said pin having a loose fit with respect to said fixed element.
Claim 5
Dependent Claim
178 words
In combination with an object, said object having at least a wheel to facilitate moving of said object, a wheel lock assembly comprising: an aperture structure formed within the hub portion of said wheel; a housing located adjacent said wheel, said housing being formed of a movable element and a fixed element, said movable element being pivotally attached to said fixed element; a biasing means located between said movable element and said fixed element; a pin connected to said movable element, said pin being capable of cooperating with said aperture structure to thereby prevent rotation of said wheel, said biasing means tending to move said pin into cooperation with said aperture structure, said pin being movable out of disassociation of said aperture structure; manually operated actuating means to facilitate movement of said movable element with respect to said fixed element; said pin being capable of a slight amount of pivotal movement with respect to said movable element; and said pin being conducted through said fixed element, said pin having a loose fit with respect to said fixed element.
