US4068858A — Bicycle — Luxuse Patents

Claim 1

Independent Claim 155 words

A bicycle including a wheeled frame, front wheel assembly pivotally connected to the frame, handlebar means for grasping by the operator, a handlebar mounting member keyed to the front wheel assembly and to which the handlebar means is secured for steering the bicycle, the improvement wherein: a. said member includes a bar portion formed with an opening recess, b. an identification plate fixedly inset in said recess and bearing identification indicia on its outwardly facing side, c. said recess defining a floor surface covered by said plate and said floor surface bearing identification data, d. said plate side and the surrounding bar surface being subjected to mutilation by efforts to tamper with said plate indicia, and said plate side and the bar surface surrounding it are disposed on the bicycle such that when the bicycle is parked upright, said plate side and its surrounding surface present themselves for ready inspection for detection of such mutilation.

Claim 2

Dependent Claim 155 words

A bicycle including a wheeled frame, front wheel assembly pivotally connected to the frame, handlebar means for grasping by the operator, a handlebar mounting member keyed to the front wheel assembly and to which the handlebar means is secured for steering the bicycle, the improvement wherein: a. said member includes a bar portion formed with an opening recess, b. an identification plate fixedly inset in said recess and bearing identification indicia on its outwardly facing side, c. said recess defining a floor surface covered by said plate and said floor surface bearing identification data, d. said plate side and the surrounding bar surface being subjected to mutilation by efforts to tamper with said plate indicia, and said plate side and the bar surface surrounding it are disposed on the bicycle such that when the bicycle is parked upright, said plate side and its surrounding surface present themselves for ready inspection for detection of such mutilation.

Claim 3

Dependent Claim 36 words

A structure of claim 1 wherein the recess is in the top of the bar portion and of a depth greater than the thickness of the plate, the walls of the recess extending above the plate.

Claim 4

Dependent Claim 170 words

A structure of claim 1 wherein the mounting member has a handlebar receiving head at one end and at the opposite end has a mounting stem head, said bar being between the two heads, and the recess is in the top of the bar, and (a) the surfaces of the top of said member and the tops of the adjacent side surfaces being free of reentering angles such as would prevent movement of a top forging die towards the top of the member for forging those surfaces; and (b) the surfaces of the bottom of said member and the bottoms of the adjacent side surfaces, being free of reentering angles such as would prevent movement of a bottom forging die towards and into forging engagement with the bottom of the member, thereby permitting forging of the top and the bottom surfaces of the member by the joint action of a top surface forging die and a bottom surface forging die both of which meet around the sides of the member.

Claim 5

Dependent Claim 188 words

A structure of claim 1 wherein the front wheel assembly includes a bicycle wheel fork and a tubular steering column extending into and journalled in the frame, and the handlebar mounting member includes a tubular shank that extends into the steering column and there is a wedge for wedging it in place, means for moving the wedge into its wedging position, said means comprising a wedge bolt extending from the top of the handlebar mounting member and thru the tubular shank, a nut threaded on the bottom of the bolt and movable longitudinally of the bolt by turning of the bolt, said nut moving towards and away from the wedge into and out of position bearing against the wedge, so that upon movement of the nut in one direction it moves the wedge into wedging position and upon movement of the nut in the opposite direction it receeds from the wedge leaving the wedge in its wedging position so that operation of the wedge bolt to move the nut in said opposite direction is ineffective to release the wedge and ineffective to allow withdrawal of the tubular shank.

Claim 6

Dependent Claim 16 words

A structure of claim 4 wherein the tubular shank is united with the handlebar mounting member.

Claim 7

Dependent Claim 176 words

A bicycle handlebar assembly including a tubular handlebar stem to which a handlebar is attachable, a front steering fork tube into which the tubular stem extends, means including a wedge for locking the two in a required position, means for moving the wedge into its locking position including a wedge bolt extending lengthwise through the tubular stem, characterized in that there is provided a nut threaded on the bolt and movable lengthwise of the bolt by turning of the bolt, said bolt moving the nut towards and away from the wedge into and out of position bearing against the wedge, so that upon movement of the nut in one direction it moves the wedge into wedging position and upon movement of the nut in the opposite direction it receeds from the wedge leaving the wedge in its wedging position so that operation of the wedge bolt to move the nut in said opposite direction is ineffective to release the wedge and ineffective to allow withdrawal of the tubular handlebar stem from the front steering fork tube.

Claim 8

Dependent Claim 176 words

A bicycle handlebar assembly including a tubular handlebar stem to which a handlebar is attachable, a front steering fork tube into which the tubular stem extends, means including a wedge for locking the two in a required position, means for moving the wedge into its locking position including a wedge bolt extending lengthwise through the tubular stem, characterized in that there is provided a nut threaded on the bolt and movable lengthwise of the bolt by turning of the bolt, said bolt moving the nut towards and away from the wedge into and out of position bearing against the wedge, so that upon movement of the nut in one direction it moves the wedge into wedging position and upon movement of the nut in the opposite direction it receeds from the wedge leaving the wedge in its wedging position so that operation of the wedge bolt to move the nut in said opposite direction is ineffective to release the wedge and ineffective to allow withdrawal of the tubular handlebar stem from the front steering fork tube.

Claim 9

Dependent Claim 16 words

The assembly of claim 6 further characterized in that the handlebar stem has identifying insignia thereon.

Claim 10

Dependent Claim 20 words

The assembly of claim 7 wherein there is an identification plate fixed on the stem over and concealing said insignia.

Claim 11

Dependent Claim 28 words

The assembly of claim 8 wherein the plate fits snugly within a recess in the stem with the walls of the recess surrounding and extending above the plate.
