Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
155 words
A sporting vehicle comprising: a frame having at least three wheels thereon, two of which are mounted for steering motion on said frame and a steering mechanism; a driving engine on said frame and having a speed control means; a transverse shaft fixed on said frame; a first bushing rotatable on said transverse shaft; a longitudinally extending shaft fixed to said first bushing; a board; at least two second bushings mounted on said board intermediate its ends, said second bushings rotatably mounted on said longitudinally extending shaft; one of said second bushings having a downwardly extending protrusion extending to said steering control mechanism whereby lateral tilting of said board around said longitudinally extending shaft effects steering movement of said two wheels; and said longitudinally extending shaft being coupled to said speed control means for controlling the speed of said engine in response to tilting of said board and longitudinally extending shaft about said transverse shaft.
Claim 2
Dependent Claim
155 words
A sporting vehicle comprising: a frame having at least three wheels thereon, two of which are mounted for steering motion on said frame and a steering mechanism; a driving engine on said frame and having a speed control means; a transverse shaft fixed on said frame; a first bushing rotatable on said transverse shaft; a longitudinally extending shaft fixed to said first bushing; a board; at least two second bushings mounted on said board intermediate its ends, said second bushings rotatably mounted on said longitudinally extending shaft; one of said second bushings having a downwardly extending protrusion extending to said steering control mechanism whereby lateral tilting of said board around said longitudinally extending shaft effects steering movement of said two wheels; and said longitudinally extending shaft being coupled to said speed control means for controlling the speed of said engine in response to tilting of said board and longitudinally extending shaft about said transverse shaft.
Claim 3
Dependent Claim
93 words
A sporting vehicle as defined in claim 1 wherein said two wheels are each journalled on means carried by upstanding axles each of which has a transverse lever and a connecting rod pivoted to each of said levers and having protrusions and comprising said steering control mechanism; said downwardly extending protrusion engaging between said protrusions of said connecting rod; said board being of shallow upwardly concave shape in transverse section and of shallow V-shape in the fore and aft direction, the rear arm of the V being shorter than the front arm thereof.
