Abstract
A sloping terrain recreational vehicle having a pair of ski-like terrain engaging elements with coupling means between them. The coupling means provides three limited degrees of freedom so that the elements can simulate skiing movements. The coupling means permits the skiis to be folded bottom-to-bottom for storage.
Claims12
A sloping-terrain vehicle comprising a pair of terrain-engaging elements;
- flexible coupling means joining said pair of terrain-engaging elements in generally side-by-side relationship to thereby permit limited movement of said terrain-engaging elements with respect to each other;
- a handlebar extending upwardly from each terrain-engaging element;
- and a foot-locating member mounted upon the upper-surface of each said terrain-engaging element, said flexible coupling means including an elongated, hollow member rigidly attached to the upper surface of each terrain-engaging element parallel to the longitudinal axis thereof;
- a pair of journal boxes each having a tongue extending from its lower side, said tongue being accommodatable within a said elongated, hollow member, adjacent its leading end, via an aperture formed in the inner wall of said elongated, hollow member;
- a pin extending through each elongated, hollow member and passing through a slot in a said tongue to thereby secure said tongue in said elongated, hollow member;
- a pair of linkage arms, the lower end of each of which is journalled in a said journal box for pivoting movement in a plane transverse to the said longitudinal axes of said terrain-engaging elements;
- and a cross-member, to each end of which is pivoted an upper end of a said linkage arm;
- whereby each said tongue is permitted three limited degrees of freedom of movement with respect to its associated elongated, hollow member.

A sloping-terrain vehicle comprising a pair of terrain-engaging elements;
- a handlebar extending upwardly from each terrain-engaging element;
- a foot-locating member mounted upon the upper surface of each terrain-engaging element;
- and flexible coupling means disposed intermediate the ends of said terrain-engaging elements and joining them in generally side-by-side relationship to thereby permit limited movement of the said terrain-engaging elements with respect to each other;
- said flexible coupling means including an elongated member rigidly attached to the upper surface of each terrain-engaging element parallel to the longitudinal axis thereof, a pair of linkage arms, one end of each of which is coupled to a said elongated member, adjacent the leading end thereof, so as to permit three limited degrees of freedom of movement with respect to its associated elongated member, and a cross-member, to each end of which is pivoted the other end of a said linkage arm;
- the said flexible coupling means permitting the vehicle to be folded so as to juxtapose the under surfaces of the two terrain-engaging elements.
