Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
208 words
A sail assembly comprising a mast, an upper elongated member fixed laterally to the mast, a lower elongated member fixed laterally to the mast and parallel to the upper member, the points of fixing of the upper and lower members to the mast are between the mid-lengths of the upper and lower members and first ends of the members, connector means including track means joining the first ends of the upper and lower members, runners engaged in the track means and fastened to flexible sail forming sheet material which extends from the track means as two panels one to either side of the mast with terminal edges of the panels adjacent the other ends of the upper and lower members, pairs of flexible elongated sail profiling elements with corresponding elements of said pairs mounted in elongated pockets in the respective sail panels so as to lie parallel to and between the upper and lower members and so as to have forward ends anchored and rear ends which extend from the sail pockets adjacent the terminal edges of the sail panels, sliding joints between rear ends of the profiling elements, and means to apply bending pressure to said elements by the application of longitudinal compressive forces to said elements.
Claim 2
Dependent Claim
208 words
A sail assembly comprising a mast, an upper elongated member fixed laterally to the mast, a lower elongated member fixed laterally to the mast and parallel to the upper member, the points of fixing of the upper and lower members to the mast are between the mid-lengths of the upper and lower members and first ends of the members, connector means including track means joining the first ends of the upper and lower members, runners engaged in the track means and fastened to flexible sail forming sheet material which extends from the track means as two panels one to either side of the mast with terminal edges of the panels adjacent the other ends of the upper and lower members, pairs of flexible elongated sail profiling elements with corresponding elements of said pairs mounted in elongated pockets in the respective sail panels so as to lie parallel to and between the upper and lower members and so as to have forward ends anchored and rear ends which extend from the sail pockets adjacent the terminal edges of the sail panels, sliding joints between rear ends of the profiling elements, and means to apply bending pressure to said elements by the application of longitudinal compressive forces to said elements.
Claim 3
Dependent Claim
34 words
A sail assembly as claimed in claim 1 wherein the connector means comprises an elongated tie member with two tracks along the length thereof respectively engaged by runners on leading edges of said panels.
Claim 4
Dependent Claim
32 words
A sail assembly as claimed in claim 1 wherein the connecter means comprises two elongated tie members each with a track therein to house runners positioned along loading edges of said panels.
Claim 5
Dependent Claim
77 words
A sail assembly as claimed in claim 1 wherein the connector means comprises an elongated tie member with a track therein to house runners located at an approximate mid-length position on the inner face of a continuous sheet of sail forming material which partially embraces said tie member and then extends rearwardly towards the other ends of said upper and lower members as said two panels with both the mast and the tie member between said panels.
Claim 6
Dependent Claim
41 words
A sail assembly as claimed in claim 2 or claim 3 including an elongated nosing having a generally U shaped body which partially embraces the connector means and said track means to provide a streamlined leading edge for said sail assembly.
Claim 7
Dependent Claim
22 words
A sail assembly as claimed in 5 wherein said nosing is mounted for part rotation about a long axis of said nosing.
Claim 8
Dependent Claim
42 words
A sail assembly as claimed in anyone of claims 2,3 or 5 wherein the nosing has flap extensions of the legs of said U shaped body to provide streamlined bridging between the profile of said nosing and the profile of said panels.
Claim 9
Dependent Claim
44 words
A sail assembly as claimed in anyone of the preceding claims wherein the means to provide bending pressure to said sail profiling elements comprises leech lines extending from the upper to the lower members and engaging the rear ends of said sail profiling elements.
Claim 10
Dependent Claim
84 words
A sail assembly as claimed in anyone of claims 1 to 8 wherein the means to provide bending pressure to said sail profiling elements comprises a plurality of lines equal in number to the number of said elements which run in the direction of the chord section of said sail assembly between fixing points where first ends of said lines respectively lie adjacent first ends of said elements and direction diverters for said lines which respectively lie adjacent the other ends of said elements.
Claim 11
Dependent Claim
34 words
A sail assembly as claimed in anyone of claims 1 to 9 wherein the leading edge and the trailing edge of the sail of the sail assembly when set are both arcs of circles.
