Abstract

A scooter device that can be propelled by side to side movement of a user is disclosed. The scooter device includes at least a first front wheel, at least a second and a third rearward located wheel, a frame structure through which the first wheel is coupled to the second and third wheels, wherein the second and third rearward located wheels are mounted in a biased direction arrangement and a steering mechanism that has a vertically ascending control member and is coupled to the first wheel such that turning of the steering mechanism achieves a turning of the first wheel, the steering mechanism further coupled to the frame structure such that the steering mechanism may be tilted relative to the frame structure. The frame structure can includes a first foot placement platform extending above the second wheel and a second foot placement platform extending above the third wheel.

First claim

What is claimed is:

1. A personal mobility vehicle comprising:
a steering unit comprising:
a right handgrip and a left handgrip;
a front wheel;
a motor operably connected with the front wheel; and
a support member;

a frame unit comprising:
a joint structure coupled with the support member such that the steering unit is tiltable relative to the frame unit;
a first leg comprising a first caster wheel; and
a second leg comprising a second caster wheel, the first and second legs being rigidly connected.

2. The personal mobility vehicle of claim 1 , wherein the first leg further comprises a first foot platform and the second leg further comprises a second foot platform.

3. The personal mobility vehicle of claim 2 , wherein the first foot platform is above the first caster wheel and the second foot platform is above the second caster wheel.

4. The personal mobility vehicle of claim 1 , wherein the frame unit further comprises a seat.

5. The personal mobility vehicle of claim 1 , wherein a shaft connects the first and second legs.

6. The personal mobility vehicle of claim 1 , wherein the joint structure extends along a longitudinal axis of the personal mobility vehicle.

7. The personal mobility vehicle of claim 1 , wherein the steering unit further comprises a first rotation member and the frame unit further comprises a second rotation member, and wherein the first and second rotation members are coaxially aligned.

8. The personal mobility vehicle of claim 1 , wherein the joint structure comprises a cylindrical shape.

9. The personal mobility vehicle of claim 1 , further comprising a handbrake operably connected with a brake assembly.

10. A personal mobility vehicle comprising:
a forward portion comprising:
a plurality of handgrips;
a front wheel;
an electric motor operably connected with the front wheel; and
a support member;

a rearward portion comprising:
a joint structure coupled with the support member such that the forward portion is tiltable relative to the rearward portion, the joint structure positioned rearward of the front wheel;
a first leg comprising a first caster wheel; and
a second leg comprising a second caster wheel.

11. The personal mobility vehicle of claim 10 , wherein the first leg further comprises a first foot platform and the second leg further comprises a second foot platform.

12. The personal mobility vehicle of claim 11 , wherein the first foot platform is above the first caster wheel and the second foot platform is above the second caster wheel.

13. The personal mobility vehicle of claim 11 , wherein a forward end of the first foot platform is cantilevered from the first leg and a forward end of the second foot platform is cantilevered from the second leg.

14. The personal mobility vehicle of claim 10 , wherein the rearward portion further comprises a seat.

15. The personal mobility vehicle of claim 10 , wherein a shaft connects the first and second legs.

16. The personal mobility vehicle of claim 15 , wherein the shaft is substantially perpendicular to a longitudinal axis of the personal mobility vehicle.

17. The personal mobility vehicle of claim 10 , wherein the support member is at an angle of about 45° relative to a longitudinal axis of the personal mobility vehicle.

18. The personal mobility vehicle of claim 10 , wherein the forward portion is tiltable relative to the rearward portion around a longitudinal axis of the personal mobility vehicle.

19. The personal mobility vehicle of claim 10 , wherein the first and second legs each comprise a respective free end.

20. The personal mobility vehicle of claim 10 , wherein the joint structure comprises a first rotation member and a second rotation member, the first and second rotation members being coaxially aligned.
