Abstract
Abstract A self-propelled vehicle wherein a platform is mounted overlying a trio of support members wherein the platform is provided with a rearwardly and upwardly extending guard overlying a caliper arrangement mounted to a central support column of the trio of columns. Forwardly the columns fixedly are mounted to a support cylinder rotatably mounting a steering column therethrough. An uppermost end of the steering column pivotally mounts a handlebar wherein the handlebar is provided with an outwardly extending handlebar flange that fixedly mounts an uppermost end of a drive link with a lowermost end of the drive link mounted eccentrically to a drive disk secured to a remote end of a axle rotatably mounting the forward wheel of the vehicle. Oscillation of the handlebar relative to the steering column rotatably drives the drive disk and the forward wheel.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
343 words
A self-propelled vehicle comprising, a pair of spaced elongate side horizontal supports integrally mounting at upper surfaces of the horizontal side supports of an elongate central platform, said platform further including a central horizontal support fixedly secured to the platform medially of said horizontal supports and terminating rearwardly of said platform with an upwardly extending rear vertical leg, said rear vertical leg mounting a brake assembly thereto to cooperate with a rear wheel positioned rearwardly of said brake assembly, and said side horizontal supports and said central support extending forwardly and upwardly relative to said platform and integrally secured to a vertically oriented support cylinder relative to said platform, and said support cylinder rotatably mounting therein a steering column, and an upper end of said steering column pivotally mounting a "U" shaped handlebar medially of said handlebar, and a lowermost end of said steering column secured to a forward wheel, and a drive means mounted to said handlebar and said forward wheel to rotate said forward wheel in response to oscillation of said handlebar relative to said steering column, and wherein said side horizontal supports extend rearwardly of said rear vertical leg and terminate in bifurcated ends to rotatably mount said rear wheel medially and rearwardly of said platform, and wherein said drive means includes a drive disk axially and integrally mounted to a first side of said forward wheel including a drive boss extending orthogonally outwardly of said drive disk and including an elongate drive link mounted rotatably at a lowermost end of the drive link to the drive boss, and wherein an upper end of the drive link is pivotally mounted to an elongate handlebar flange, and said handlebar flange includes a forward end pivotally mounting said drive link and includes a rear end integrally secured to the handlebar, and wherein the handlebar includes a connecting leg wherein the handlebar flange is mounted offset from a central portion of said connecting leg and wherein said handlebar flange includes an encircling flange cylinder to integrally secure said handlebar flange to said handlebar.
Claim 2
Dependent Claim
343 words
A self-propelled vehicle comprising, a pair of spaced elongate side horizontal supports integrally mounting at upper surfaces of the horizontal side supports of an elongate central platform, said platform further including a central horizontal support fixedly secured to the platform medially of said horizontal supports and terminating rearwardly of said platform with an upwardly extending rear vertical leg, said rear vertical leg mounting a brake assembly thereto to cooperate with a rear wheel positioned rearwardly of said brake assembly, and said side horizontal supports and said central support extending forwardly and upwardly relative to said platform and integrally secured to a vertically oriented support cylinder relative to said platform, and said support cylinder rotatably mounting therein a steering column, and an upper end of said steering column pivotally mounting a "U" shaped handlebar medially of said handlebar, and a lowermost end of said steering column secured to a forward wheel, and a drive means mounted to said handlebar and said forward wheel to rotate said forward wheel in response to oscillation of said handlebar relative to said steering column, and wherein said side horizontal supports extend rearwardly of said rear vertical leg and terminate in bifurcated ends to rotatably mount said rear wheel medially and rearwardly of said platform, and wherein said drive means includes a drive disk axially and integrally mounted to a first side of said forward wheel including a drive boss extending orthogonally outwardly of said drive disk and including an elongate drive link mounted rotatably at a lowermost end of the drive link to the drive boss, and wherein an upper end of the drive link is pivotally mounted to an elongate handlebar flange, and said handlebar flange includes a forward end pivotally mounting said drive link and includes a rear end integrally secured to the handlebar, and wherein the handlebar includes a connecting leg wherein the handlebar flange is mounted offset from a central portion of said connecting leg and wherein said handlebar flange includes an encircling flange cylinder to integrally secure said handlebar flange to said handlebar.
Claim 3
Dependent Claim
40 words
A self-propelled vehicle as set forth in claim 1 wherein the steering column includes a cylindrical yoke mounted orthogonally to an upper end of said steering column and wherein said yoke rotatably receives said handlebar medially of the connecting leg.
Claim 4
Dependent Claim
