Abstract

Various powered unicycles are disclosed. In some embodiments, the powered unicycle includes a central wheel, a motor to power the central wheel, and a control system configured to control the application of power from the motor to the central wheel. The unicycle comprises a body portion and at least one platform for supporting the user. The unicycle can includes a handle that extends upwardly to a position that it can be grasped by a user of the unicycle. The handle can be partially or fully retractable into the body of the unicycle. In some configurations, two platforms upon which the user can stand are provided with one on each side of the central wheel. In some configurations, a pair of auxiliary or outrigger wheels is provided, such as with one outrigger wheel on each side of the central wheel.

First claim

What is claimed is:

1. A powered unicycle comprising:
a central wheel;
a motor to power the central wheel;
a control system configured to control the application of power from the motor to the central wheel;
a body portion;
at least one platform for supporting a user in a standing position;
a handle that extends upwardly from the body portion to a position such that the handle can be grasped by the user of the unicycle; and
a first outrigger wheel and a second outrigger wheel;
wherein the unicycle is configured such that, during riding, the central wheel and the first and second outrigger wheels contact the ground and an axis of rotation of the first outrigger wheel and an axis of rotation of the second outrigger wheel are positioned between a front edge and a rear edge of the at least one platform;
wherein the at least one platform comprises two platforms upon which the user can stand, a first of the two platforms being positioned on a first axial side of the central wheel and a second of the two platforms being positioned on a second axial side of the central wheel; and
wherein a portion of each of the first and second platforms can pivot relative to the body, the pivoting portion being positioned outboard of a respective one of the first and second outrigger wheels.

2. The powered unicycle of claim 1 , wherein the handle is at least partially retractable into the body of the unicycle.

3. The powered unicycle of claim 1 , wherein the first outrigger wheel is positioned on the first axial side of the central wheel and the second outrigger wheel is positioned on the second axial side of the central wheel.

4. The powered unicycle of claim 3 , wherein the first and second outrigger wheels are centered with respect to the central wheel in a fore-aft direction of the unicycle, along which the unicycle is configured to travel.

5. The powered unicycle of claim 4 , wherein each of the first and second outrigger wheels is coupled to one of the platforms.

6. The powered unicycle of claim 3 , further comprising a suspension element or arrangement positioned between the body and each of the first and second outrigger wheels.

7. The powered unicycle of claim 6 , wherein the suspension element is positioned between a swingarm for each of the first and second outrigger wheels and the at least one platform.

8. The powered unicycle of claim 3 , wherein mounts for the first and second outrigger wheels are integrated or unitary with the first and second platforms.

9. The powered unicycle of claim 3 , wherein a position of the first and second outrigger wheels can be adjusted.

10. The powered unicycle of claim 9 , wherein a lateral position of the first and second outrigger wheels is adjustable.

11. The powered unicycle of claim 10 , wherein a first outrigger wheel assembly comprises the first outrigger wheel and a second outrigger wheel assembly comprises the second outrigger wheel, wherein the first platform and the first outrigger wheel assembly and the second platform and the second outrigger wheel assembly comprise a respective flange and slot arrangement, which allows the lateral position of the first and second outrigger wheels to be adjusted between at least two available positions.

12. A powered unicycle comprising:
a central wheel;
a motor to power the central wheel;
a control system configured to control the application of power from the motor to the central wheel;
a body portion;
a first platform and a second platform for supporting a user in a standing position;
a handle that extends upwardly from the body portion to a position such that the handle can be grasped by the user of the unicycle;
a first outrigger wheel spaced laterally away from the central wheel; and
a second outrigger wheel spaced laterally away from the central wheel;
wherein a lowermost point of the first and second outrigger wheels is aligned with a lowermost point of the central wheel; and
wherein at least a portion of the first and second platforms can pivot relative to the body, each pivoting portion being positioned outboard of a respective one of the first and second outrigger wheels.

13. The powered unicycle of claim 12 , wherein a position of the first and second outrigger wheels is adjustable.

14. The powered unicycle of claim 12 , wherein the first outrigger wheel is positioned on a first axial side of the central wheel and the second outrigger wheel is positioned on a second axial side of the central wheel.

15. The powered unicycle of claim 12 , wherein the first and second outrigger wheels are centered with respect to the central wheel in a fore-aft direction of the unicycle, along which the unicycle is configured to travel.

16. The powered unicycle of claim 12 , further comprising a suspension element or arrangement positioned between the body and each of the first and second outrigger wheels.

17. The powered unicycle of claim 12 , wherein a position of the first and second outrigger wheels can be adjusted relative to the first and second platforms.

18. A powered unicycle comprising:
a central wheel;
a motor to power the central wheel;
a control system configured to control the application of power from the motor to the central wheel;
a body portion;
a first platform and a second platform for supporting a user in a standing position;
a handle that extends upwardly from the body portion to a position such that the handle can be grasped by the user of the unicycle; and
a first outrigger wheel assembly comprising a first outrigger wheel and a second outrigger wheel assembly comprising a second outrigger wheel, the first outrigger wheel being positioned on a side of the central wheel and the second outrigger wheel being positioned on another side of the central wheel;
wherein the unicycle is configured such that, during riding, the central wheel and the first and second outrigger wheels contact the ground and an axis of rotation of the first outrigger wheel and an axis of rotation of the second outrigger wheel are positioned between a front edge and a rear edge of the at least one platform; and
wherein the first platform and the first outrigger wheel assembly and the second platform and the second outrigger wheel assembly comprise a respective flange and slot arrangement, which allows the lateral position of the first and second outrigger wheels to be adjusted between at least two available positions.

19. The powered unicycle of claim 18 , wherein the first and second outrigger wheels are centered with respect to the central wheel in a fore-aft direction of the unicycle, along which the unicycle is configured to travel.

20. The powered unicycle of claim 18 , further comprising a suspension element or arrangement positioned between the body and each of the first and second outrigger wheels.

21. The powered unicycle of claim 18 , wherein the first and second platforms comprise the slot and the first and second outrigger wheel assemblies comprise the flange.
