Abstract
Abstract A sport vehicle having a support ski supporting a frame, a steering ski mounted on the frame and adapted to be aligned with the support ski and outrigger skis having flexible connections to the frame to permit individual displacement of each outrigger ski by the foot between a normal position parallel to the axis of the frame and a plowing position in which the outrigger ski points forwardly and inwardly toward the longitudinal axis of the frame and in which the outer edge of the ski is elevated relative to its inner edge.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
211 words
A sport vehicle comprising steering and support ski elements, a frame normally mounting said ski elements in longitudinally aligned coplanar relation parallel to the longitudinal axis of said frame, a handlebar mounting said steering element on said frame for pivotal movement about a substantially upright axis to afford steering of said vehicle, a seat on said frame overlying said support element to support the driver, outrigger foot skis disposed outwardly and forwardly of said seat for receiving the feet of the driver, and flexible connection means mounting said foot skis on said frame for individual movement by the driver''s foot from normal positions parallel to each other and to said longitudinal axis, to plowing positions out of said parallel relationship and at an angle pointing forwardly and inwardly toward the longitudinal axis of said frame, said flexible connecting means including an outrigger arm pivoted to said frame about an axis parallel to said longitudinal frame axis and a second pivotal connection pivoting said foot ski to said arm about an axis spaced from said parallel axis inclined rearwardly relative to the longitudinal axis of said frame, whereby said flexible connecting means positions the outer longitudinal edge of said foot ski upwardly relative to its inner longitudinal edge in said plowing position.
Claim 2
Dependent Claim
211 words
A sport vehicle comprising steering and support ski elements, a frame normally mounting said ski elements in longitudinally aligned coplanar relation parallel to the longitudinal axis of said frame, a handlebar mounting said steering element on said frame for pivotal movement about a substantially upright axis to afford steering of said vehicle, a seat on said frame overlying said support element to support the driver, outrigger foot skis disposed outwardly and forwardly of said seat for receiving the feet of the driver, and flexible connection means mounting said foot skis on said frame for individual movement by the driver''s foot from normal positions parallel to each other and to said longitudinal axis, to plowing positions out of said parallel relationship and at an angle pointing forwardly and inwardly toward the longitudinal axis of said frame, said flexible connecting means including an outrigger arm pivoted to said frame about an axis parallel to said longitudinal frame axis and a second pivotal connection pivoting said foot ski to said arm about an axis spaced from said parallel axis inclined rearwardly relative to the longitudinal axis of said frame, whereby said flexible connecting means positions the outer longitudinal edge of said foot ski upwardly relative to its inner longitudinal edge in said plowing position.
Claim 3
Dependent Claim
49 words
A sport vehicle according to claim 1 including a pivot having a transverse horizontal axis mounting said support ski on said frame adjacent the longitudinal midpoint of said ski, and a flexible link connected between said ski and said frame to limit the vertical pivotal movement of said ski.
Claim 4
Dependent Claim
24 words
A vehicle according to claim 2 wherein said flexible link comprises an arm and a spring affording limited vertical displacement and preventing lateral displacement.
Claim 5
Dependent Claim
36 words
A sport vehicle according to claim 1 including a hand lever on said handlebar and a towing device maintained operative by said hand lever, whereby upon release of said lever said towing device is rendered inoperative.
Claim 6
Dependent Claim
52 words
A vehicle according to claim 4 wherein said towing device comprises a hook lever pivoted on said frame, a displaceable retaining rod restraining pivotal movement of said hook lever, and means connecting said hand lever to said retaining rod to effect release of said hook lever upon release of said hand lever.
