Three-wheeled rear-steering scooter
A three wheeled scooter comprises a chassis having forward and aft ends with a front wheel non-pivotally mounted to the forward end and a pair of rear wheels coaxially mounted to the aft end. The chassis defines a longitudinal axis and includes a support assembly and a handle assembly extending upwardly from the support assembly. The rear wheels are configured to be angularly yawable relative to the longitudinal axis between a neutral position and a yawed position. Steering of the scooter is thereby effectuated by angular yawing of the rear wheels relative to the longitudinal axis such as by asymmetric loading of one of opposing sides of the support assembly.
1. A three-wheeled scooter, comprising;
a chassis having forward and aft ends;
a front wheel non-pivotally mounted to the forward end of the chassis;
a pair of rear wheels coaxially mounted to the aft end of the chassis and being yawable between a neutral position and a yawed position;
wherein:
steering of the scooter is effectuated by angular yawing of the rear wheels relative to the longitudinal axis.
2. The three-wheeled scooter of claim 1 , further comprising a foot support connected to the chassis; and
wherein, in order to turn the three-wheeled scooter, a user rolls the foot support about a longitudinal axis defined by the chassis.
3. The three-wheeled scooter of claim 1 , wherein the foot support straddles the front wheel.
4. The three-wheeled scooter of claim 1 , wherein the front wheel and the pair of rear wheels are the only wheels.
5. The three-wheeled scooter of claim 1 , wherein when the pair of rear wheels are yawed, each of the pair of rear wheels remains co-axial with the other of the pair of rear wheels.
6. The three-wheeled scooter of claim 1 , further comprising a pair of handgrips.
7. The three-wheeled scooter of claim 6 , wherein the pair of handgrips are placed directly over a hub of the front wheel.
8. The three-wheeled scooter of claim 1 , wherein the front wheel has a larger diameter than the pair of rear wheels.
9. The three-wheeled scooter of claim 8 , wherein the foot support straddles the front wheel.
10. A three-wheeled scooter, comprising;
a chassis having forward and aft ends;
a front wheel non-pivotally mounted to the forward end of the chassis;
a pair of rear wheels coaxially mounted to the aft end of the chassis and being yawable-between a neutral position and a yawed position; and
a foot support connected to the chassis, the foot support having a first side and a second side;
wherein, to turn the scooter to the first side, a user rolls the foot support to the first side, so that the first side is lower than the second side, and to turn the scooter to the second side, the user rolls the foot support to the second side, so that the second side is lower than the first side.
11. The three-wheeled scooter of claim 10 , wherein the foot support straddles the front wheel.
12. The three-wheeled scooter of claim 10 , wherein the front wheel and the pair of rear wheels are the only wheels.
13. The three-wheeled scooter of claim 10 , wherein when the pair of rear wheels are yawed, each of the pair of rear wheels remains co-axial with the other of the pair of rear wheels.
14. The three-wheeled scooter of claim 10 , further comprising a pair of handgrips.
15. The three-wheeled scooter of claim 14 , wherein the pair of handgrips are placed directly over a hub of the front wheel.
16. The three-wheeled scooter of claim 10 , wherein the front wheel has a larger diameter than the pair of rear wheels.
17. The three-wheeled scooter of claim 16 , wherein the foot support straddles the front wheel.
