| Abstract: |
A three-wheeled cambering vehicle having a platform for supporting the vehicle operator and having a pair of laterally spaced rear wheels mounted thereon. The vehicle has a centralized tubular frame with a front leg member that supports a steerable front fork and wheel assembly and a rearward seat for the vehicle operator. A lower leg of the frame is supported for turning movement with respect to a longitudinal roll axis by the platform which permits the frame and front fork and wheel assembly to be cambered by the vehicle operator as the platform remains in a predetermined plane with respect to the support surface.

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:
1. A cambering vehicle for transporting a vehicle operator along a support surface, said vehicle comprising a centralized main frame having an upwardly extending forward frame member and a lower tubular frame member extending along the longitudinal axis of the vehicle rearwardly from the lower end of said forward frame member to the rear of said vehicle, steerable front wheel means supported by said forward frame member for contacting said support surface, manual steering means operatively connected to said steerable front wheel means, a seat for a vehicle operator attached to said lower frame member, a one-piece support platform extending to the rear of said vehicle from said forward frame member and laterally across said lower frame member for receiving the feet of the vehicle operator, bearing means operatively connecting said lower frame member to said platform for supporting said frame on said platform for free cambering movement about a longitudinal roll axis coplanar with the longitudinal axis of said platform, transverse axle means rotatably supporting the central frame secured to said platform, rear wheel means underlying said seat means and supported on opposite outboard ends of said axle means for contacting said support surface to support said platform in fixed angular relationship with respect to said support surface while allowing the operator when seated to impart balancing moments through his feet while cambering said central frame and said front wheel means.
