Abstract
Abstract Sailboard comprising a sail assembly and a floatboard (2) supporting the sail assembly. The sail assembly comprises two wings (4, 5) in relatively displaced relation to each other, the two wings having substantially parallel leading edges (6, 7), the two wings being connected together by a rigid supporting frame ensuring a constant relative positioning of the wings. One (7) of those leading edges has an end (7a) which is removably and pivotably laid upon the floatboard (2), thus permitting the user to move the sail assembly during navigation between a position where the end (7a) of that one leading edge is pivotably laid upon the floatboard and a position where the sail assembly is dissociated from the floatboard and maintained by the user in a substantially horizontal position to produce a sustentation effect.

Total Claims: 18
Claim 1
Independent Claim
158 words
Sailboard comprising a sail assembly and a floatboard (2) supporting said sail assembly, said sail assembly comprising two wings (4, 5) in relatively displaced relation to each other, said two wings having substantially parallel leading edges (6, 7), said two wings being connected together by supporting frame ensuring at least in use a constant relative positioning of said wings, this supporting frame being provided with gripping means (8, 10) for the user, the leading edge (7) of a first one (5) of the wings having an end (7a) which is removably and pivotably laid upon the floatboard (2), thus permitting the user to move the said sail assembly during navigation between a position where said end (7a) of said leading edge of said first wing is pivotably laid on the floatboard and a position where said sail assembly is dissociated from the floatboard and maintained by the user in a substantially horizontal position to produce a sustentation effect.
Claim 2
Dependent Claim
158 words
Sailboard comprising a sail assembly and a floatboard (2) supporting said sail assembly, said sail assembly comprising two wings (4, 5) in relatively displaced relation to each other, said two wings having substantially parallel leading edges (6, 7), said two wings being connected together by supporting frame ensuring at least in use a constant relative positioning of said wings, this supporting frame being provided with gripping means (8, 10) for the user, the leading edge (7) of a first one (5) of the wings having an end (7a) which is removably and pivotably laid upon the floatboard (2), thus permitting the user to move the said sail assembly during navigation between a position where said end (7a) of said leading edge of said first wing is pivotably laid on the floatboard and a position where said sail assembly is dissociated from the floatboard and maintained by the user in a substantially horizontal position to produce a sustentation effect.
Claim 3
Dependent Claim
46 words
A sailboard according to claim 1, wherein a second one (4) of the wings is pivoted with respect to the frame adjacent the leading edge of said second wing and wherein trailing edges (4b, 5b) of the wings are connected together by a flexible connecting means.
Claim 4
Dependent Claim
34 words
A sailboard according to claim 2, comprising a stretcher rod which is pivoted with respect to the frame and connects the leading edge (6) and the trailing edge (4b) of the second wing (4).
Claim 5
Dependent Claim
79 words
A sailboard according to claim 1, wherein the frame comprises two incurvated members (10) extending along the first wing (5) outside a space (103) between the wings (4, 5), each said incurvated member (10) connecting a trailing edge (5b) of the first wing (5) to the leading edge (7) thereof and to the leading edge (6) of the second wing (4), said two incurvated members (10) being spaced apart from each other adjacent each said leading edge (6, 7).
Claim 6
Dependent Claim
26 words
A sailboard according to claim 4, wherein the elongate members (10) are connected to each other adjacent the trailing edge (5b) of the first wing (5).
Claim 7
Dependent Claim
44 words
A sailboard according to claim 5, wherein each leading edge (6, 7) comprises two edge bars (15, 16) articulated together between the incurvated members (10), and the incurvated members (10) are articulated to eachother adjacent said trailing edge (5b) of the first wing (5).
Claim 8
Dependent Claim
80 words
A sailboard according to claim 1 wherein each wing (4, 5) comprises adjacent its leading edge (6, 7) two half edge bars (15a) articulated to each other so as to be able to fan out from a folded position to a service position, and wherein the frame is of a foldable type and couples the half edge bars (15a) of the two wings (4, 5) for simultaneous faning out movement of both wings (4, 5) and unfolding of the frame.
Claim 9
Dependent Claim
29 words
A sailboard according to claim 7, wherein each wing (4, 5) comprises slats (17) which diverge from adjacent a position where the half edge bars (15a) are articulated together.
Claim 10
Dependent Claim
39 words
A sailboard according to claim 1 wherein each wing (4, 5) comprises slats (17), each slat (17) comprising a tube (107) tapering from a trailing edge (4b, 5b) to the leading edge (6, 7) of the wing (4, 5).
Claim 11
Dependent Claim
