US4941670A — Ride-on device for transportation and stunt riding

Claim 1

Independent Claim 177 words

A transportation and stunt riding device adapted for use on a supporting surface comprising: a V-shaped frame having a first arm and a second arm and a longitudinal axis, said first arm and said second arm being fixed with respect to each other; upper and lower body stabilization and support means mounted on said frame; at least two wheel mounting means mounted to said frame and having at least four wheels rotatably attached to said at least two wheel mounting means adapted to be powered by at least one of potential and kinetic energy, the direction of travel of said device being governed by the non-perpendicular positioning of the frames relative to the supporting surface; wherein one of said wheel mounting means includes front wheel mounting means defined by a first plate pivotally connected to the second arn of the V-shaped member by a stub axle integrally mounted on the first plate and passing through sleeve attached to the second arm of the V-shaped member, at least one wheel engaging axle permanently affixed to said first plate.

Claim 2

Dependent Claim 177 words

A transportation and stunt riding device adapted for use on a supporting surface comprising: a V-shaped frame having a first arm and a second arm and a longitudinal axis, said first arm and said second arm being fixed with respect to each other; upper and lower body stabilization and support means mounted on said frame; at least two wheel mounting means mounted to said frame and having at least four wheels rotatably attached to said at least two wheel mounting means adapted to be powered by at least one of potential and kinetic energy, the direction of travel of said device being governed by the non-perpendicular positioning of the frames relative to the supporting surface; wherein one of said wheel mounting means includes front wheel mounting means defined by a first plate pivotally connected to the second arn of the V-shaped member by a stub axle integrally mounted on the first plate and passing through sleeve attached to the second arm of the V-shaped member, at least one wheel engaging axle permanently affixed to said first plate.

Claim 3

Dependent Claim 17 words

The device according to claim 1 further comprising braking means for braking at least one said wheel.

Claim 4

Dependent Claim 28 words

The device according to claim 1 wherein the apex of the V-shaped member allows resilient movement of the arms of said V-shaped member with relation to each other.

Claim 5

Dependent Claim 38 words

The device according to claim 1 wherein the upper body stabilization and support means comprise handle bars mounted perpendicularly to the longitudinal axis of said device at an upper end of the first arm of the V-shaped member.

Claim 6

Dependent Claim 51 words

The device according to claim 4 further comprising means for rotatably mounting said handle bars on the frame through ninety degrees and in one position substantially aligned and coplanar with the longitudinal axis of the device, in another position substantially perpendicular to the longitudinal axis of the device, to facilitate storage.

Claim 7

Dependent Claim 60 words

The device according to claim 1 wherein the lower body stabilization and support means are defined by a seat mounted on the first arm of the V-shaped member intermediate an upper end of the first arm of the V-shaped member and the apex of the V-shaped member, and foot support means mounted on the second arm of the V-shaped member.

Claim 8

Dependent Claim 18 words

The device according to claim 6 wherein the seat is affixed to the first arm of the V.

Claim 9

Dependent Claim 113 words

The device according to claim 1 wherein rear wheel mounting means are defined by a second plate connected to the second arm of the V-shaped member by a bracket and mechanical fasteners, said mechanical fasteners passing the second plate and attaching said second plate to the bracket, said bracket being affixed to the second arm of the V-shaped member, resilient spacing members being located so as to allow angular displacement of the first second plate relative to the bracket whilst maintaining a substantially perpendicular orientation between the axis of the wheels and the longitudinal axis of said second arm, and at least one wheel engaging axle being permanently affixed to the second plate.

Claim 10

Dependent Claim 115 words

The device according to claim 1 wherein an angle defines the non-perpendicular positioning of the frame relative to the supporting surface, such adjustment of said angle causing the second plate to rotate about an axis substantially parallel to the longitudinal axis of the device and the second plate to rotate about an axis defined by the axis of the stub axle passing through the sleeve attached to the frame, a change on the center of gravity of the device and second plate creating an overturning moment such that the second plate and attached wheels oppose said overturning moments and the first plate and attached wheels rotate to change the direction of travel of the device.

Claim 11

Dependent Claim 47 words

The device according to claim 1 wherein the lower end of the sleeve is configured rearward of the upper end of the sleeve such that an included angle between a longitudinal axis of the sleeve and the longitudinal axis of the device is between 30° and 89°.

Claim 12

Dependent Claim 168 words

A transportation and stunt riding device adapted for use on a supporting surface comprising: a V-shaped frame member having a first arm and a second arm fixed with respect to each other; upper and lower body stabilization and support means mounted on said frame; at least two wheel mounting means mounted to said frame having at least four wheels rotatably attached to said at least two wheel mounting means adapted to be powered by at least one of potential and kinetic energy, the direction of travel of said device being governed by the non-perpendicular positioning of the frame relative to the supporting surface; braking means including a resilient pad extending longitudinally rearward from the second arm of the V-shaped member adapted to engage the supporting surface over which the device travels, thereby braking the wheels by the application of a downward force to the pad, thus causing the device to lose energy through frictional contact between the pad and the supporting surface over which the device is travelling.

Claim 13

Dependent Claim 168 words

A transportation and stunt riding device adapted for use on a supporting surface comprising: a V-shaped frame member having a first arm and a second arm fixed with respect to each other; upper and lower body stabilization and support means mounted on said frame; at least two wheel mounting means mounted to said frame having at least four wheels rotatably attached to said at least two wheel mounting means adapted to be powered by at least one of potential and kinetic energy, the direction of travel of said device being governed by the non-perpendicular positioning of the frame relative to the supporting surface; braking means including a resilient pad extending longitudinally rearward from the second arm of the V-shaped member adapted to engage the supporting surface over which the device travels, thereby braking the wheels by the application of a downward force to the pad, thus causing the device to lose energy through frictional contact between the pad and the supporting surface over which the device is travelling.
