Abstract
Abstract A vehicle combining features of skis and of a bobsleigh in which a normally upright frame carrying a seat for rider is equipped with a ski-like front runner and a similar rear runner, the front runner being mounted on a steering column. A universal pivot assembly located closely adjacent the axis of the steering column connects the rear end of the front runner to the front end of the rear runner. The steering column is attached to the frame by means of a bearing which pivots in the longitudinal upright plane of the frame and is hingedly linked to the hingedly mounted seat so that the weight of the rider tends to pivot the bearing in a direction to draw the two runners into longitudinal alignment.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
154 words
A snow vehicle comprising, in combination: a. frame means extending in an upright plane in the normal operating position of said vehicle; b. a seat for a rider on said frame means; c. a rear runner mounted on said frame means and downwardly spaced from said seat in said position of the vehicle, l. said rear runner being elongated substantially in said plane; d. an elongated front runner, l. said runners having respective longitudinally terminal front and rear portions; e. steering means connecting a portion of said front runner intermediate said terminal portions thereof to said frame means for movement toward and away from a position in which said runners are longitudinally aligned, l. said movement being angular about an axis extending in said plane; and f. pivot means connecting the terminal rear portion of said front runner to the terminal front portion of said rear runner for angular movement substantially about said axis.
Claim 2
Dependent Claim
154 words
A snow vehicle comprising, in combination: a. frame means extending in an upright plane in the normal operating position of said vehicle; b. a seat for a rider on said frame means; c. a rear runner mounted on said frame means and downwardly spaced from said seat in said position of the vehicle, l. said rear runner being elongated substantially in said plane; d. an elongated front runner, l. said runners having respective longitudinally terminal front and rear portions; e. steering means connecting a portion of said front runner intermediate said terminal portions thereof to said frame means for movement toward and away from a position in which said runners are longitudinally aligned, l. said movement being angular about an axis extending in said plane; and f. pivot means connecting the terminal rear portion of said front runner to the terminal front portion of said rear runner for angular movement substantially about said axis.
Claim 3
Dependent Claim
51 words
A vehicle as set forth in claim 1, wherein said steering means include a bearing member mounted on said frame means for pivoting movement in said plane, and a steering column operatively connected to said intermediate portion of the front runner and angularly movable on said bearing member about said axis.
Claim 4
Dependent Claim
39 words
A vehicle as set forth in claim 2, including a spring interposed between said frame means and said bearing member and biasing said bearing member to pivot in said plane in a direction to move said runners longitudinally apart.
Claim 5
Dependent Claim
56 words
A vehicle as set forth in claim 2, wherein said seat is movably mounted on said frame means, and linkage means connecting said seat and said bearing member for pivoting the bearing member in said plane in response to the weight of said rider on said seat in a direction to move said runners longitudinally apart.
Claim 6
Dependent Claim
28 words
A vehicle as set forth in claim 4, wherein said linkage means include a train of sequentially connected linking members, one of said linking members being a spring.

Dependent Claim
36 words
A vehicle as set forth in claim 5, wherein said train includes two elongated members, one of said members being received in the other member for telescoping movement, said spring being interposed between said two members.
Claim 8
Dependent Claim
91 words
A vehicle as set forth in claim 2, further comprising a lever member mounted on said frame means for pivotal movement in said plane and carrying said seat, and linkage means connecting said lever member to said bearing member for pivoting said bearing member in response to the weight of a rider on said seat, said pivot means permitting relative angular movement of said runners about two axes Transverse to each other, said rear runner being hingedly mounted on said frame for pivoting movement in the plane of said frame means.
Claim 9
Dependent Claim
26 words
A vehicle as set forth in claim 7, wherein said linkage means include a compression spring operatively interposed between said lever member and said bearing member.
