Abstract
Abstract The invention relates to light, sailing vehicles equipped with at least one sail fixed on a mast and attached to a boom. The mast is supported toward its middle part at the top of a two-legged support, in the form of an inverted V, and mounted rigidly on the frame of the vehicle, while the foot of the mast is mounted in such a manner as to be capable of sliding along a cross member substantially perpendicular to the plane of symmetry of said frame and shifted toward the front with respect to the transverse plane passing through the top of the two-legged support.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
189 words
A vehicle equipped with a frame including a plurality of parallel cross members including a front and back cross member, oppositely disposed parallel longitudinally extending rods joined to said plurality of cross members, a mast secured at one end to said front cross member, at least one sail fixed on said mast and attached on a boom having a trailing portion including a tack, a two-legged support means forming an inverted V, said two-legged support means mounted at a lower end thereof for slidable movement on said oppositely disposed longitudinally extending rods, said mast being supported for articulation approximately at its middle part by an upper end of said two-legged support means, and at its lower end in such a manner as to assume a longitudinal position which is regulatable in order to vary the rake of the mast, and said mast includes a foot having roller means arranged to roll along said front cross member mounted forward of said longitudinally extending rods to thereby enable said mast to move laterally along said front cross member and the trailing portion of said boom is guided along a control means.
Claim 2
Dependent Claim
189 words
A vehicle equipped with a frame including a plurality of parallel cross members including a front and back cross member, oppositely disposed parallel longitudinally extending rods joined to said plurality of cross members, a mast secured at one end to said front cross member, at least one sail fixed on said mast and attached on a boom having a trailing portion including a tack, a two-legged support means forming an inverted V, said two-legged support means mounted at a lower end thereof for slidable movement on said oppositely disposed longitudinally extending rods, said mast being supported for articulation approximately at its middle part by an upper end of said two-legged support means, and at its lower end in such a manner as to assume a longitudinal position which is regulatable in order to vary the rake of the mast, and said mast includes a foot having roller means arranged to roll along said front cross member mounted forward of said longitudinally extending rods to thereby enable said mast to move laterally along said front cross member and the trailing portion of said boom is guided along a control means.
Claim 3
Dependent Claim
42 words
A sailing vehicle as defined by claim 1, further characterized in that said tack is provided with a point of anchorage serving as a means for attachment carried by a further roller means capable of sliding on said rearwardly disposed cross member.
Claim 4
Dependent Claim
60 words
A sailing vehicle as defined by claim 1, characterized in that the front cross member for guiding the foot of the mast further includes a tube bent into the general shape of an elongated U, said elongated U having end portions which are arranged for limited movement relative to said longitudinally extending rods positioned above the frame of the vehicle.
Claim 5
Dependent Claim
45 words
A sailing vehicle as defined by claim 1, characterized in that the lower ends of the two-legged support for the mast further include a telescoping structure thereby to permit vertical displacement of the top of said two-legged support whenever the lower ends are displaced laterally.
