Abstract

A motorized "stand-up" snow vehicle comprising a frame having a driving means thereon, a forward steering ski controlled by a steering unit which extends to a height above the frame sufficient to be easily grasped by a standing operator. The steering unit is a vertical steering rod causing turning to the right when its upper end is moved to the right.

Claims

1. A motorized stand-up snow vehicle comprising a frame, said frame having forward and rearward ends and right and left sides, a driving means mounted on said frame and having portions extending beneath said frame for engaging surfaces over which said vehicle is traveling, a steering ski disposed beneath said frame and disposed forwardly of said driving means, said driving means and said ski elevating said frame from said surfaces means mounting a central part of said ski on said frame for the rotation of said ski about an upright axis so that the forward end of said ski can be moved to the right or left, a steering rod extending upwardly from said frame to a point sufficient to be easily grasped by a rider who is standing on said frame, steering train means operably correlating said rod and said ski so that a lateral movement to the right of the top of said rod causes movement to the right of the front of said ski, means pivotally connecting the lower end of said rod to said frame for the movement of the top of said rod to the right and left of said frame, a foot-supporting platform mounted on said frame and having an upper surface of a size for supporting thereon at least one of an operator'"'"'s feet, there being a standing space disposed rearwardly of said rod which is substantially open for a distance extending back from said rod sufficient for the standing of the operator in such space.

2. The motorized stand-up snow vehicle of claim 1 having said surface-engaging portion being a flexible belt means, a plurality of pulleys in horizontal row disposed inside said flexible belt means and a forward pulley inside said flexible belt means and disposed substantially higher on its underside than the pulleys of said row, means rotatably mounting said pulleys on said frame, and an idler pulley attached to said frame and pressing against the upper side of said belt between said forward pulley and the rearwardmost pulley of said row so as to maintain said belt taut.

3. The motorized stand-up snow vehicle of claim 1 having said steering train means comprising said steering rod extending through said frame, lower pivot means attaching said steering rod to the rearward end of said ski, upper pivot means slidably and rotatably attaching said steering rod to said frame for vertical sliding of said steering rod with respect to said frame so that said ski can move up and down and for permitting said steering rod to swing to the left and right at its upper end so as to cause opposite motions of the rearward end of said ski, said means mounting said ski with said frame being forwardly of said steering rod.

4. The motorized stand up snow vehicle of claim 1 in which said steering rod has a rotating handle mounted on its upper end, said steering rod being hollow, a throttle cable assembly extending upwardly through said steering rod, the lower end of said throttle cable assembly extending out of said steering rod and rearwardly to said engine, and means operatively correlating said rotating handle and said throttle cable assembly so that as said handle is rotated in opposite directions said throttle cable assembly will cause opposite motions of a throttle wire in said throttle cable assembly.

5. The motorized stand-up snow vehicle of claim 4 having said handle inclining forwardly at its upper end so as to be pointed away from the operator for safety.

6. The motorized stand-up snow vehicle of claim 1 having said steering rod having an elongated upwardly extending handle at its upper end, said handle inclining forwardly at its upper end so as to be pointed away from the operator for safety.

7. The motorized stand-up snow vehicle of claim 3 having said steering rod extending up from the level of said upper surface of said foot-supporting platform a suitable distance, said distance being over 24 inches.

8. The motorized stand-up snow vehicle of claim 7 having said distance being over 28 inches.

9. The motorized stand-up snow vehicle of claim 7 having said steering rod having a rotating handle mounted on its upper end, said steering rod being hollow, a throttle cable assembly extending upwardly through said steering rod, the lower end of said throttle cable assembly extending out of said steering rod and rearwardly to said engine, and means operatively correlating said rotating handle and said throttle cable assembly so that as said handle is rotated in opposite directions said throttle cable assembly will cause opposite motions of a throttle wire in said throttle cable assembly.

10. The motorized stand-up snow vehicle of claim 2 having said steering rod extending through said body, lower pivot means attaching said steering rod to the rearward end of said ski, upper pivot means slidably and rotatably attaching said steering rod to said frame for vertical sliding of said steering rod with respect to said frame so that said ski can move up and down and for permitting said steering rod to swing to the left and right at its upper end so as to cause opposite motions of the rearward end of said ski, said means mounting said ski with said frame being forwardly of said steering rod, said steering rod having a rotating handle mounted on its upper end, said steering rod being hollow, a throttle cable assembly extending upwardly through said steering rod, the lower end of said throttle cable assembly extending out of said steering rod and rearwardly to said engine, and means operatively correlating said rotating handle and said throttle cable assembly so that as said handle is rotated in opposite directions said throttle cable assembly will cause opposite motions of a throttle wire in said throttle cable assembly.

11. The motorized stand-up snow vehicle of claim 1 having said steering rod being provided with a collapsible section, said steering rod having a support section below said collapsing section, rod section attaching means releasably interconnecting said collapsible section and said other section in a manner for holding said sections substantially rigid with respect to each other for use and in a manner for permitting said collapsing section to be bent downwardly for shipment, said rod section attaching means being manually disposable into a position permitting collapsing and into a position for holding said collapsing section and said support section substantially rigid with respect to each other.

12. The motorized stand-up snow vehicle of claim 11 having said rod section attaching means being a rigid sleeve extendable over adjacent portions of said collapsible rod section and said support rod section.
