Abstract
Abstract A ski bob comprising a frame and a pair of axially aligned runners in which the front runner is steerable by handlebars pivotally mounted on the frame and one of the runners, usually the rear runner, is provided with a rotating mechanism so that it may be rotated about a longitudinal axis for transverse movement relative to the frame so that the runner is caused to ''''edge'''' as the bob turns in snow. The rotating mechanism is controlled by a twist grip on the handlebars.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
133 words
In a ski-bob or like apparatus for sliding on snow, including a frame; at least one runner to support said frame; and connecting means to attach said runner to said frame; the improvement according to which said connecting means comprise: a casing secured to said frame; an endless screw rotatably supported by said casing and extending substantially transversely of said runner; a gear sector pivotably supported by said frame about an axis substantially longitudinal to said runner, said sector being in mesh with said endless screw; means to secure said gear sector to said runner so as to maintain same at a fixed angular position with respect to said sector about said axis; and means to rotate sAid endless screw in both directions to tilt said runner transversely with respect to said frame.
Claim 2
Dependent Claim
133 words
In a ski-bob or like apparatus for sliding on snow, including a frame; at least one runner to support said frame; and connecting means to attach said runner to said frame; the improvement according to which said connecting means comprise: a casing secured to said frame; an endless screw rotatably supported by said casing and extending substantially transversely of said runner; a gear sector pivotably supported by said frame about an axis substantially longitudinal to said runner, said sector being in mesh with said endless screw; means to secure said gear sector to said runner so as to maintain same at a fixed angular position with respect to said sector about said axis; and means to rotate sAid endless screw in both directions to tilt said runner transversely with respect to said frame.
Claim 3
Dependent Claim
133 words
In a ski-bob or like apparatus for sliding on snow, including a frame; at least one runner to support said frame; and connecting means to attach said runner to said frame; the improvement according to which said connecting means comprise: a casing secured to said frame; an endless screw rotatably supported by said casing and extending substantially transversely of said runner; a gear sector pivotably supported by said frame about an axis substantially longitudinal to said runner, said sector being in mesh with said endless screw; means to secure said gear sector to said runner so as to maintain same at a fixed angular position with respect to said sector about said axis; and means to rotate sAid endless screw in both directions to tilt said runner transversely with respect to said frame.
Claim 4
Dependent Claim

In a ski-bob or like apparatus for sliding on snow, including a frame; at least one runner to support said frame; and connecting means to attach said runner to said frame; the improvement according to which said connecting means comprise: a casing secured to said frame; an endless screw rotatably supported by said casing and extending substantially transversely of said runner; a gear sector pivotably supported by said frame about an axis substantially longitudinal to said runner, said sector being in mesh with said endless screw; means to secure said gear sector to said runner so as to maintain same at a fixed angular position with respect to said sector about said axis; and means to rotate sAid endless screw in both directions to tilt said runner transversely with respect to said frame.
Claim 5
Dependent Claim
47 words
In a ski-bob or like apparatus as claimed in claim 1, said means to secure said gear sector to said runner comprising: a support rigidly secured to said runner; and means to pivot said gear sector to said support about an axis substantially transverse to said runner.
Claim 6
Dependent Claim
90 words
In a ski-bob or like apparatus as claimed in claim 2: said runner having an upper side; said support including a sill rigidly secured onto the upper side of said runner, and a pair of lateral lugs solid with said sill, with said gear sector situated between said lugs; and said means to pivot said gear sector to said support comprising a pair of opposed pins rotatably carried by said lugs along said substantially transverse axis, each of said pins having a threaded inner end screwed into said gear sector.
Claim 7
Dependent Claim
