A wheeled vehicle comprising a rigid body having a forwardly projecting front end, a single front wheel rotatably journalled on the front end of the body for rotation about a transverse axis in fixed relation to the body, foot-operated drive means connected with said front wheel for rotation thereof in a selected direction, said body including a rear end, a forwardly facing occupant seat mounted on said body adjacent the rear end thereof in position for an occupant to manually manipulate the drive means for the front wheel, a rear axle extending transversely of the rear end of the body, a wheel supported from each end of the axle for rotation, means supporting said axle from said body for swinging movement of the axle about an axis extending upwardly and rearwardly with respect to the path of movement of the vehicle in response to the occupant of the seat shifting his weight laterally of the path of movement of the vehicle thereby steering the vehicle, said means supporting said axle from said body including a pivot pin fixed to the center of the axle in substantially perpendicular relation thereto, an upwardly and rearwardly inclined bearing sleeve rigid on said body and journalling said pin therein, the upper end of said pin projecting above the sleeve, a transversely extending cross head on the upper end of said pin, said cross head being parallel to said axle and spaced upwardly and rearwardly in relation thereto, and manually manipulated means connected to each end of the cross head and supported from the body at a position forwardly of the seat to enable an occupant of the seat to manually control swinging movemenT of the axle about the upwardly and rearwardly inclined axis formed by the sleeve journalling the pivot pin, said body including a rearwardly and downwardly curved rear end, said upwardly and rearwardly inclined sleeve being rigid with the rear lower end of the downwardly curved rear end of the body, said cross head being disposed adjacent the upper end of the sleeve and swingable in a plane intersecting a portion of the rear end of the body whereby the body will limit swinging movement of the cross head and axle.

A wheeled vehicle comprising a rigid body having a forwardly projecting front end, a single front wheel rotatably journalled on the front end of the body for rotation about a transverse axis in fixed relation to the body, foot-operated drive means connected with said front wheel for rotation thereof in a selected direction, said body including a rear end, a forwardly facing occupant seat mounted on said body adjacent the rear end thereof in position for an occupant to manually manipulate the drive means for the front wheel, a rear axle extending transversely of the rear end of the body, a wheel supported from each end of the axle for rotation, means supporting said axle from said body for swinging movement of the axle about an axis extending upwardly and rearwardly with respect to the path of movement of the vehicle in response to the occupant of the seat shifting his weight laterally of the path of movement of the vehicle thereby steering the vehicle, said means supporting said axle from said body including a pivot pin fixed to the center of the axle in substantially perpendicular relation thereto, an upwardly and rearwardly inclined bearing sleeve rigid on said body and journalling said pin therein, the upper end of said pin projecting above the sleeve, a transversely extending cross head on the upper end of said pin, said cross head being parallel to said axle and spaced upwardly and rearwardly in relation thereto, and manually manipulated means connected to each end of the cross head and supported from the body at a position forwardly of the seat to enable an occupant of the seat to manually control swinging movemenT of the axle about the upwardly and rearwardly inclined axis formed by the sleeve journalling the pivot pin, said body including a rearwardly and downwardly curved rear end, said upwardly and rearwardly inclined sleeve being rigid with the rear lower end of the downwardly curved rear end of the body, said cross head being disposed adjacent the upper end of the sleeve and swingable in a plane intersecting a portion of the rear end of the body whereby the body will limit swinging movement of the cross head and axle.
Claim 3
Dependent Claim
64 words
The structure as defined in claim 1 wherein the forwardly extending front end of the body includes a rigid bifurcated front fork assembly, said front wheel being journalled in the fork assembly, said drive means including crank arm supported pedals rotatable with the drive wheel, the rotational axis of the drive wheel being fixed with respect to the fork assembly, body and occupant seat.
Claim 4
Dependent Claim
92 words
The structure as defined in claim 2 wherein said means connected to the ends of the cross head include a pair of pivotal levers supported from the body at the front of the occupant seat, and rods connecting the respective levers with the corresponding ends of the cross head whereby the levers may be employed to control the steering movement of the vehicle and also serve to stabilize the person occupying the seat, said forwardly extending fork assembly being oriented with substantially one-half of the front wheel disposed above the fork assembly.
