Definitions

  • the present invention relates to sail winders and relates more particularly although not exclusively to jib winders.
  • Jib furlers generally include a drum mounted at the bottom of the forestay and on which is wound an actuating cord.
  • the drum is intended to drive in rotation a tube for receiving the sail, surrounding the forestay cable and one end of which is made to rotate with said drum.
  • the winding tube of the sail is made up of sections of tube with closed contour juxtaposed and riveted end to end.
  • the tube thus formed requires for its installation the disassembly of the forestay cable in order to thread the sleeve on said cable.
  • the tube is rotatably mounted on the forestay cable via plastic bearings.
  • Such an arrangement has good resistance to torsion, but it is difficult to assemble.
  • reels whose winding tube is produced by assembling two open sections: Although they can be mounted without detaching the forestay cable, the tubes produced in two half-tubes have the disadvantage of a very poor resistance to torsion.
  • the invention aims to remedy the drawbacks of winders of the prior art by creating a sail furler whose tube combines the resistance to twisting of closed contour tubes with the ease of mounting the tubes produced by assembling open sections.
  • a winding tube of a sail in particular for jib furler, made of at least one metal section mounted for rotation at stay of the forestay cable, characterized in that the metal profile has an outer profile of circular cross-section defining the winding surface of the tube and an inner profile in the form of an open eight, made integrally with the outer profile, the profiles exterior and interior being interconnected at a common longitudinal slot, the interior profile forming a housing for a plastic sheath also of eight section which defines, after engagement in the interior profile and pinching, a first compartment for the reception of the detai cable and a second compartment forming a luff groove opening into said slot common to the exterior and interior profiles.
  • the jib furler shown in FIG. 1 mainly comprises a drum 1 fixed to the lower part of the forestay cable 2 and to the tack point of the forestay cable on the bow E of a sailboat.
  • the drum 1 comprises a rotary pulley 3 on which is wound a rope 4 which passes through a drosse guide 5 of the drum and one end of which is immobilized at a point on the deck of the sailboat, a tensile force exerted on the rope 4 causing the rotation of the pulley 3 which is integral in rotation with a tube 6 surrounding the forestay cable 2 and to which the jib 7 is fixed in a manner which will be described later.
  • the jib receiving tube 6 is produced in several sections 8 of aluminum profiles arranged end to end and assembled by connection sleeves 9 fixed to the sections 8 by rivets 10.
  • each section of tube 8 has an outer profile 11 of practically circular section and with an inner profile 12 of eight-shaped section open as a matter of course with the outer profile, the outer 11 and inner 12 profiles opening onto a common longitudinal slot 13
  • the connection sleeve 9 is engaged against the internal surface of the external profile 11. It also has a slot 14 whose edges bear against the surface of the internal profile 12.
  • the internal profile 12 in the shape of an open eight defines a first central housing 15 intended to receive the forestay cable 16 and a lateral housing 17 in which the headline 18 of the sail 7 must be engaged.
  • the forestay cable 16 and the rope 18 are held inside their respective housings 15 and 17 formed in the inner profile 12 by means of a sheath 19 of plastic material also having an eight-shaped cross section.
  • the sheath 19 has a thickness such that it practically fills the gap between the forestay cable 16 and the internal profile 12 in the first housing 15 and that it leaves a minimum clearance between the headline 18 and the internal wall of the housing lateral 17.
  • the sheath 19 is slightly pinched. so that.
  • the sheath 12 has internal ribs 20 facing one another.
  • the part of the sheath 19. surrounding the rope 18 has flats 21 defining a V-shaped groove leading to a slot 22 intended to allow the sail 7 to pass.
  • the mounting of the reel according to the invention is carried out as follows. After having dismantled the forestay cable, a slide 22 for operating the sail 7 is put in place with the jib halyard 23 as well as the drum 1. The forestay cable 2 is then put back in place. mounting on the forestay cable of the winding tube 6 made up of sections of profiles 8 with external 11 and internal 12 profiles, assembled end to end using the connection sleeves 9. At its upper end, the winding has a stop 24. When the winding tube 8 is in place around the forestay cable, it is hoisted by threading on it le_coulisseau 22 on which one acts using the halyard 23 up. that it is in contact with the stop 24 to drive the winding tube 6 upwards.
  • the sheath 12 is slightly pinched during its assembly, so that it practically encloses completely the forestay cable 16 'and that it cannot in any way come out of its compartment thus defined.
  • the sheath constitutes a rotation bearing for the winding tube.
  • the part of the sheath 19 located in the lateral housing 17 constitutes a groove for the headline 18 of the sail 7, so that when the sheath 19 is put in place, it then suffices to mount the sail as in a ordinary headline throat.
  • the winding tube of the sail 8 is finished, it suffices to fix its lower end to the drum 1 and the reel is then ready to operate.
  • the winding tube 8 has a practically circular profile so that the winding of the sail takes place in very good conditions, without forming folds.
  • the winding tube 8 Due to its composite profile, the winding tube 8 has a very high torsional rigidity.
  • the sheath 19 allows rotation of the tube 8 on the forestay cable 16 with a minimum of friction.
