Abstract
A scooter device propelled by side to side movement of a user that includes a frame structure through which at least a front wheel is coupled to two direction biased rear wheels. The biased direction wheels include tilted caster and spring biased caster arrangements. The frame structure may have a rear support member or structure that extends between the two rear wheels. A user support platform of various configurations may be provided with the rear support member or structure. The scooter may have a three wheel configuration with the front wheel being larger than the rear two wheels.
Claims19
A scooter device propelled by side to side movement of a user, comprising:
- at least a first forward located wheel;
- at least a second and a third rearward located wheel, the second and third rearward located wheels mounted in a biased direction arrangement;
- a frame structure through which the first wheel is coupled to the second and third wheels, the frame structure including a rear support member extending substantially continuously between the second and third wheels;
- and
- a shaped human support platform coupled to and extending above the rear support member, the human support platform being positioned above a central portion of the rear support member;
- 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;
- wherein the rear support member includes a second wheel support section that extends toward the second wheel and a third wheel support section that extends toward the third wheel, each of the second wheel support section and the third wheel support section having a lateral dimension that is greater than its longitudinal dimension.

A scooter device propelled by side to side movement of user, comprising:
- at least a first forward located wheel;
- at least a second and a third rearward located wheel, the second and third rearward located wheels mounted in a biased direction arrangement;
- a frame structure through which the first wheel is coupled to the second and third wheels, the frame structure including a principal longitudinal frame member and a principal rear support member that extends substantially outwardly from the frame member to the second and third wheels;
- a steering mechanism that has a vertically ascending control member and is coupled to the first wheel such that a turning of the steering mechanism achieves a turning of the first wheel;
- and
- wherein the rear support member includes a second wheel support section that extends from the frame member toward the second wheel and a third wheel support section that extends from the frame member toward the third wheel, each of the second wheel support section and the third wheel support section having a lateral dimension that is greater than its longitudinal dimension;
- wherein the steering mechanism and first wheel are arranged such that for steering purposes there is a singular front wheel which is the first wheel;
- and
- wherein, during use, the rear support member is fixedly coupled to the longitudinal frame member such that the rear support member does not move relative to the longitudinal frame member.
