Abstract
Abstract A velocipede having a single driving wheel which is powered by rotating pedals that rotate a sprocket that is connected to the driving wheels by a chain. A roller assembly comprises small diameter rollers having a roller axis that is disposed lower than and in front of the pedal axis. The rollers are connected to the velocipede frame by a bearing member so that the rollers can be articulated allowing the rider to lean on the velocipede thereby controlling the direction of movement.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
149 words
A velocipede comprising a frame, a seat mounted on said frame, a pedal bracket secured to said frame and rotatably mounting pedals about a pedal axis, chain and sprocket transmission means drivingly connecting said pedals to a single driving wheel, said single driving wheel being rotatable about a wheel axis disposed at the rear of said frame, a roller assembly mounted on said frame comprising relatively small diameter roller means rotatable about a roller axis, said roller axis being disposed lower than said pedal axis and said wheel axis, said pedal axis being disposed longitudinally between said roller axis and said wheel axis and adjacent said roller axis, means for articulating said roller assembly forwardly of said roller axis about an inclined articulation axis for enabling the rider to lean the velocipede laterally to either side of a longitudinal plane for controlling the direction of movement of the velocipede.
Claim 2
Dependent Claim
149 words
A velocipede comprising a frame, a seat mounted on said frame, a pedal bracket secured to said frame and rotatably mounting pedals about a pedal axis, chain and sprocket transmission means drivingly connecting said pedals to a single driving wheel, said single driving wheel being rotatable about a wheel axis disposed at the rear of said frame, a roller assembly mounted on said frame comprising relatively small diameter roller means rotatable about a roller axis, said roller axis being disposed lower than said pedal axis and said wheel axis, said pedal axis being disposed longitudinally between said roller axis and said wheel axis and adjacent said roller axis, means for articulating said roller assembly forwardly of said roller axis about an inclined articulation axis for enabling the rider to lean the velocipede laterally to either side of a longitudinal plane for controlling the direction of movement of the velocipede.
Claim 3
Dependent Claim
45 words
The velocipede of claim 1, wherein said means for articulating said roller assembly comprises a forwardly extending pivot fixed to the roller assembly cooperating with a complementary bearing member provided on a roller assembly mounting member secured to the lower front end of said frame.
Claim 4
Dependent Claim
27 words
The velocipede of claim 1, wherein said roller assembly mounting member is fixed on a horizontal plate rigidly fixed to said lower front end of said frame.
Claim 5
Dependent Claim
16 words
The velocipede of claim 1, wherein said roller assembly means is part of a skateboard truck.
Claim 6
Dependent Claim
55 words
The velocipede of claim 1, wherein a shock absorbing member is operatively disposed between said roller assembly and said roller assembly mounting member for absorbing shocks when said roller assembly pivots about said articulation axis and restoring said roller assembly to a centered position as the rider brings the velocipede back to a straight position.
Claim 7
Dependent Claim
39 words
The velocipede of claim 2, wherein means are provided for adjustably mounting the angular position of said mounting member on said frame about an axis generally parallel to said roller axis in the centered position of said roller assembly.
Claim 8
Dependent Claim
51 words
The velocipede of claim 6, wherein said means for adjustably mounting the angular position of said mounting member comprises cooperable serrated members in radial array respectively fixed relative to said frame and said mounting member and a clamping member for urging said serrated members in clamping relation in the desired position.
Claim 9
Dependent Claim
14 words
The velocipede of claim 1, wherein said articulation axis in inclined downwardly and rearwardly.
