Definitions

• the present invention relates to a device for guiding the rope of a sail.
• This invention is particularly applicable to pre-guiding a luff rope, for example a mainsail or a genoa, before its introduction into the groove of a mat or a genoa furler.
• Known lambs pre-guides are usually constituted by a crescent-shaped rigid piece, connected to a support by its middle portion, and whose ends are spaced a distance greater than the thickness of the sail to allow its sliding between said ends, and less than the thickness of the headline to prevent the headline from leaving the pre-guide when the sail slides in the latter.
• the installation of the headline in the pre-guide is achieved by passing one of its ends in the pre-guide.
• a major disadvantage of such devices lies in the fact that when the user hoists his sail in conditions where efforts are important (strong wind for example), or when the headline is damaged, and that it falls off the meadow -guide, then the user must lower his sail completely to find the end of headline, iron this end in the pre-guide and hoist the sail again.
• the technical problem to be solved is to provide a pre-guide luff allowing quick set-up and withdrawal with respect to the headline, at any point of the length thereof.
• the present invention solves this problem by providing a device for guiding the headline of a sail, characterized in that it comprises two jaws curved and fixed to one another around a pivot point, the first jaw being provided with an inwardly directed extension comprising a flat portion and a notch, the second jaw including a U-shaped locking loop made of steel wire mounted on said second jaw at both ends of the U and capable of pivoting elastically around an equilibrium position in which:
• the median portion of the loop in the closed position of the device, is engaged in the notch in a removable manner in order to keep the two jaws close to each other by a distance less than the diameter of the headline and greater than the thickness of the sail, and - In the open position of the device, the middle portion of the loop rests on the flat portion of the extension to keep the two jaws apart from each other by a distance greater than the thickness of the headline.
• the locking loop comprises two arms of unequal length, whose ends have pivot points relative to the second jaw which are offset longitudinally.
• This configuration of the two attachment points of the ends of the loop makes it possible to generate an elastic return effect when the latter is displaced on either side of its equilibrium position.
• the device comprises a recess defined by the two jaws, and disposed between the pivot and the locking loop.
• This recess allows the passage of a fastener such as a rope. Fixing the rope will be performed for example by two knots at the rope located on either side of the device.
• the pivot point of the two jaws is advantageously constituted by a rivet.
• Figure 1 is a partial side view of a sail engaged in two devices according to the invention
• FIG. 1 shows a mainsail 1 being hoisted in a sail carrier formed by the rope groove 2 of a mast 3, sail 1 whose luff 4 is provided with a rope 5 slidably inserted into two
• Each device 6 is fixed, in a manner that will be specified hereinafter, at a distance from each other along an end 8 - or rope - itself attached to the sail carrier (mast, section d reel, hollow stay ). Most often, only one pre-guide is used for setting up a sail.
• This end 8 makes a pull of the pre-guides 6 and the free portion of the sail 1 towards the mast 3 as shown in Figure 1 by an arrow, to facilitate the insertion of the headline 5 in the neckline groove 2 of the mast.
• the pre-guide rope 6 device comprises two jaws 9, 10 curved and fixed to one another by one of their ends around a pivot point 11 formed by a rivet.
• the first jaw 9 is provided with an extension 12 directed inwardly comprising a flat portion 13 and a notch 14.
• the second jaw 10 is equipped with a U-shaped locking loop 15 made of wire mounted articulated on the second jaw 10 at both ends thereof, and resiliently pivoting about an equilibrium position.
• the two pivot points 18 of the ends of the branches are offset longitudinally.
• the middle portion 16 of the rod 15 rests on the flat portion 13 of the extension 12 in order to keep the two jaws 9, 10 away from each other. other, greater than the diameter of the headline 5.
• the middle portion 16 of the rod 15 is engaged in the notch 14, in order to keep the two jaws 9, 10 close to each other. a distance less than the diameter of the rope 5 and greater than the thickness of the sail 1, so that the sail can slide in the pre-guide rope 6, but not the headline. can escape from the space between the jaws
• the curved jaws 9, 10 of the device 6 of the invention have a shape such that a closed recess 19 is provided between the two jaws 9, 10, the extension 12 and the locking rod 15.
• This space 19 allows the attachment of the end 8 - or rope - described above and shown in Figure 1.
• Each of the pre-guides rope 6 device according to the invention is prevented from sliding along the tip 8 through nodes 20 made on either side of the corresponding device, as shown in Figure 1, nodes whose diameter is greater than the diameter of the space 19 of passage of the tip.
