Definitions

  • the present invention relates to a rigging intended in particular, but not exclusively for windsurfing boards and in particular for boards known under the name of "fun-board".
  • Patent EP-A-0 031 074 describes a rigging for windsurfing mounted on an articulated mast foot and comprising a closed frame, with longitudinal symmetry on which the sail is established, a transverse spar of maneuver taking support from on either side of the frame.
  • the upper part of the frame is arched in its plane while the lower part, resting on the mast foot, consists of a triangle.
  • the object of the present invention is to remedy the drawbacks of known rigging and to propose a rigging having an improved yield compared to those of the known technique.
  • the rigging for nautical or land craft mounted on an articulated mast foot and comprising a sail established on a closed frame with axis of longitudinal symmetry whose upper end is arched in at least one plane, and a spar bearing on the frame, is characterized in that the sail at rest is cut in the shape of an ellipsoid sector defining a concave face and a convex face, two flexible uprights, arched in two perpendicular directions, constituting the frame and secured to the sail, being joined at their upper and lower parts, the spar being mounted on the side of the concave face of the sail.
  • the rigging is characterized in that the uprights are stretched by at least one cable extending substantially in the longitudinal direction of the sail between the common point and the upper part of the rigging, at least one tension means being arranged on the cable.
  • the uprights are arched in their plane and in a plane perpendicular to their rest position so as to cause the sail to take on the shape of an ellipsoid sector, an operating spar or boom having a concavity opposite to that of the taut sail.
  • the rigging according to the invention gives the sail the form of an "orange quarter" subtended by flying buttresses. We know that this structure is extremely resistant and the rigging thus formed can use the best wind energy.
  • the operating spar is disposed between the vertical uprights substantially at one third of the height thereof.
  • each of the uprights constituting the mast is provided, at the height of the boom, with an arcticula- tion.
  • the rigging can bend thus avoiding breaking.
  • the sail 1 is stretched on uprights 2 connected by their upper 3 and lower 4 ends, the lower end 4 resting on the board P by means of a joint 16.
  • the articulated mast foot 16 allows the rigging to move in all desired positions above the horizontal plane. It is known that the performance of a sail in the vicinity of the water surface is poor taking into account the irregularity of the air currents at this level. A certain consistency in the direction is found only slightly higher and according to a characteristic of the invention, the sail is somewhat vertical, the ratio of its height to its width being greater than that of an ordinary sail. Thus, the role of irregular surface air currents in driving the board is minimized.
  • the uprights 2 are stretched by one or more cables 7 by means of tensioners 10 (Fig.
  • This rigging is used like a classic rigging to progress in the different directions but it facilitates the jibe of the sail since this one being symmetrical, the boarder makes it pass in front of him perpendicular to the direction of the wind, and not in the bed of it, which reverses the leading edge and the trailing edge on the other purlin. There is therefore no more loss of power during the jibe, the sail not having to be erased in flag at any time.
  • the concave shape of the sail increases its power and its non-deformability by the vertical cables which force the tubes to play the role of flying buttresses counterbalancing the traction of the rider on the boom.
  • the uprights 2 can be made for example of a light metal alloy such as aluminum or of glass or carbon fibers included in a suitable resin.
  • the sail has a form of ellipsoid sector.
  • a cable 8 can be mounted between the uprights 2 so that they do not deviate excessively in a vertical plane at the expense of bending. It is also possible to use a frame such as that shown in FIG. 3, the upper part of which has a larger sail area than the lower part, the uprights 2 being brought together again at their upper 3 and lower 4 ends.
  • Fig. 4 shows the mounting of the sail 1 on an upright 2 thanks to a sheath fitted with lacing means 31, either of the Velcro type (registered trademark) in the evening by a buttoning or zipper system. Eyelets 27 mounted from place to place on the height of the upright 2 allow the sail to be stretched towards the ends of the tube using a rope not shown.
  • This sail mounting system and the geometrical structure of the sail make it very easy to obtain a reduction in the sail area by trapping the sail. It suffices to separate the upper part of the sail from the uprights 2 and to wind it up to the desired height as shown diagrammatically at 32 in FIG. 1.
  • the rigging is constituted by a sail 1 established on two symmetrical uprights 2 joined at their upper 3 and lower 4 ends, the uprights 2 being braced by a cable 7 stretched by a hoist 10.
  • a boom 5 of rounded shape allows the rigging to be maneuvered, the cable 7 not being linked to the boom or spar 5.
  • the cable or cables 7 pass outside of the boom 5 so that the inclination of this allows to adjust the tension of the cable and consequently the hollow of the sail.
  • the boom 5 is fixed to the uprights 2 by ropes.
  • the symmetrical shape of the rig allows the establishment of a sail or thick.
  • the surface of the upper surface 11 of the sail always remains the same, that is to say that contrary to what occurs in a sail with a conventional ply, the function of faces of the sail is not modified during use.
  • This rigging is therefore particularly suitable for receiving a second sheet of fabric 12 intended to constitute the surface of the pressure surface, the conformation of which will be, during use, different from that of the surface of the pressure surface 11.
  • the sail according to another characteristic of the invention comprises two sheets 11 and 12 of fabric joined at their ends by two sleeves 14 in which the uprights 2 are included, as this appears on a larger scale in FIG. 7.
  • the underside sheet 12 undergoes the pressure of the wind and takes a slightly marked curvature, while the face of the suction face 11 subjected to a greater depression than the pressure takes a more marked curvature. , in relation to the flow of the air streams on the face 11.
  • a lining 13 which may be either a layer of plastic foam, or even a set of slats or more generally any rigid or semi-rigid material maintaining a spacing between the two layers.
  • the plies are, for example sewn so that the tensions on each of the plies do not tend to equalize and that there is therefore no interaction between the plies.
  • the tensioned rigging according to the invention being slightly deformable is subjected to considerable forces in the breaking blades when it is not held by its user after falling into the water.
  • the cable 7 collects the forces from the rear towards the front while the articulation bends in the opposite direction.
  • the articulation 28 provided on each of the uprights is of course blocked by a calibrated retaining piece, playing the role of brake. As shown in Fig.
  • the rigging can bend from position I to position Il around the joints 28 when the forces exerted on the rigging are too great and correspond to the setting of the brake
  • the inward folding can be done freely reducing the size of the rigging at the height of the upper branch thereof, or substantially two thirds of the height of sailing.
  • the boom 5 is also provided with a hinge 29 so as to allow complete folding of the rigging.
  • the present invention can be implemented whenever it is intended to use wind power and in particular on sailboats, on sailboards, on “speed-sails” (registered trademark) and on sailboards. casters (wind-skates).
