Definitions

  • the present invention relates to a new type of sail for gear such as windsurfing, sand yachting, sailing boat and more generally for all board sports such as for example skiing and ice skating and casters.
  • the sails currently used have the characteristic, whatever their shape, of using the force of the wind by pivoting around a vertical axis; the propellant component then being perpendicular to this axis.
  • the present sail belongs to this new type of sail capable of orienting itself along the three axes in order to obtain propulsive and lift effects at will.
  • the present invention relates to a sail which has a stable convex profile of the gull wing type. Indeed, a concave profile always tends to turn over in strong wind since if one moves it away from its position of equilibrium where the two halves of the sail offer the same surface, perpendicular to the wind, one of the halves receives more and more wind while the other receives less and less, unlike a convex “V” profile which always tends to bring the sail back to its equilibrium position.
  • a convex “V” profile facilitates the flow of air, and during gusts, it tends to close, thereby dampening the swings in the wind.
  • a sail with variable propulsive and lift effects comprising support and return elements allowing changes of edge, and comprising a single wing without thickness and mounted on a frame having a leading edge of shaped “V diverging towards the rear known from document DE-A-2833616 is characterized in that it has a strongly curved central section, in the vicinity of the top of the leading edge, concave in the wind and progressively continuing more straight towards its end and a trailing edge joining the two ends of the leading edge of said rear end to form two divergent sides.
  • the central section can be slightly convex and its rear end to present an asymmetrical S shape.
  • the sail may have a support element remote from the wing under the latter and two return bars diverging forward from said rear end, for example forming a triangular system with the support bar.
  • the sail comprises a framework of substantially rigid elongated elements, in particular tubular, and a wing stretched over the framework with, preferably, a set of pre-cambered slats concave to the wind near the leading edge.
  • the connections between the frame elements can advantageously be flexible to facilitate a certain deformability of the sail, the shape of which is maintained by its own tension.
  • FIG. 1 is a side view and from below
  • FIG. 2 is a view from below
  • FIG. 3 is a front view with a small rotation
  • Figures 4 and 5 are detail views.
  • the sail 1 with a stable convex profile in the form of gull's alleys is made up of a set of trapezoidal portions of fabric made up together giving it the general appearance of a sector of a circle and provided with two transparent windows 2 for good operator's vision.
  • the sail 1 is stretched over a light alloy frame composed of: two border tubes 3 fitted into a curved front tube 4, a central tube 7 slightly bent along an “S” profile serving to form the convex transverse “V” profile by the action of the two stretching tubes 5 on the link 12 and finally a curved support tube 6.
  • the border tubes 3 pass inside strips of leather respectively secured by means of the screws 15 of the stretching tubes 5 and of the support tube 6 before fitting into the interior of the curved front tube 4 bearing on the stops 17; the tanks 16 hold the tubes 5 and the tube in position 6.
  • the detail 12 in FIG. 5 shows the stretching of the sail using the cords 19 passing through the eyelet 18.
  • the sail can be used alone or optionally connected to a mast 20 of the vehicle to be propelled.
  • the mast 20 can for example be connected to the machine by a first ball joint 21 while the other end is connected to the sail by a sleeve 22 sliding on the support bar 6 with a second ball joint 23.
  • edge changes are made by planking the sail followed by passing it over the operator's head with immediate wind pickup on the other edge; this technique is much easier and faster than the conventional way of changing edges by tilting the mast backwards and passing the operator in front of it, as is done with the current sails of windsurfers.
  • the multiple possible orientations of the sail make it possible to create a propulsive force having the effect of pulling the machine forward and upwards and this more or less large lift depending on the desired size of the sail must also allow high speeds due to the resulting aqua-planning effect for light vehicles.
