Segmental sail for boats

Claim 2

A sectional sail for boats including in reciprocal combination and cooperation a plurality of sections parallel to one side of the sail, each of said sections being provided with a luff-rope and a leech-rope at the fore and aft vertical edges of said sections, and means for tensioning and tightening said ropes; stiffening battens arranged on said sections betwen said luff- and leech-ropes and extending substantially from edge to edge of said sections for maintaining a constant distance between the edges for entry and exit of the wind between said sections; means for securing the ends of said sections, and means for connecting the edges of said sections, said ends of said sections being substantially aligned and axially successive.

Claim 3

The sectional sail of claim 1 wherein said sail is triangular and said sections are parallel to one side of the triangle.

Claim 4

The sectional sail of claim 1 wherein said sail is polygonal and said sections are parallel to at least one side of the polygon.

Claim 5

The sectional sail of claim 1 wherein the tightening of the luff- and leeech-ropes can be adjusted and is brought about with means which operate gradually.

Claim 6

The sectional sail of claim 4 wherein the means for gradually tightening the luff- and leech-ropes have a threaded sleeve and a threaded rod which cooperate mutually.

Claim 7

The sectional sail of claim 1 wherein the tensioning means consist of boltropes and stays.

Claim 8

The sectional sail of claim 1 wherein the tensioning means consist of boltropes or stays which cooperate with a border containing a plurality of eyelets.

Claim 9

The sectional sail of claim 1 wherein the means for tightening the luff- and leech-ropes are secured to at least one boltrope or stay.

Claim 10

The sectional sail of claim 1 wherein the means for tightening the luff- and leech-ropes are secured to at least one border that cooperates with at least one boltrope or stay.

Claim 11

The sectional sail of claim 1 wherein the means for tightening the luff- and leech-ropes are secured to at least one end of each of said sections.

Claim 12

The sectional sail of claim 1 wherein said sections are secured at their ends to boltropes or stays and lie substantially on a plane passing through the axis of said boltrope or stay.

Claim 13

The sectional sail of claim 1 wherein said sections are secured at their ends to border means and lie substantially on a plane passing through the axis of boltropes or stays.

Claim 14

The sectional sail of claim 1 wherein the means for securing said sections can be removed.

Claim 15

The sectional sail of claim 1 wherein spacer battens having two attachment elements are applied to said luff- and leech-ropes and contain a seating for a spacer element.

Claim 16

The sectional sail of claim 1 wherein spacer battens are contained in holding pockets present in said sections.

Claim 17

The sectional sail of claim 1 wherein the means for connecting the ends of said sections connect the entry edge of one section to the exit edge of the preceding section.

Claim 18

A sectional sail for boats including in reciprocal combination and cooperation a plurality of sections parallel to one side of the sail, each of said sections being provided with a luff-rope and a leech-rope at the fore and aft vertical edges of said sections, and means for gradually tensioning and tightening said ropes; stiffening battens for maintaining a constant distance between the edges for entry and exit of the wind between said sections; means for securing the ends of said sections, and means for connecting the edges of said sections, said ends of said sections being substantially aligned and axially successive; and said means for gradually tensioning and tightening said luff- and leech-ropes having in reciprocal cooperation and combination a pin with a retaining head with external threading, with a threaded axial bore and a perpendicular bore; a flange which is frontally hollow and has a radial slit; a locking ring nut cooperating with the external threading of the pin, and a clamping screw cooperating with the axial threaded bore of the pin.

Claim 19

A sectional sail for boats including in reciprocal combination and cooperation a plurality of sections parallel to one side of the sail, each of said sections being provided with a luff-rope and a leech-rope at the fore and aft vertical edges of said sections, and means for gradually tensioning and tightening said ropes; stiffening battens for maintaining a constant distance between the edges for entry and exit of the wind between said sections; means for securing the ends of said sections, and means for connecting the edges of said sections, said ends of said sections being substantially aligned and axially successive; and said means for gradually tensioning and tightening said luff- and leech-ropes having in reciprocal cooperation and combination a pin with a retaining head with external threading, with a threaded axial bore and a perpendicular bore; a flange which is frontally hollow and has a radial slit; a locking ring nut cooperating with the external threading of the pin, and a clamping screw cooperating with the axial threaded bore of the pin.
