Definitions

  • the present invention relates to a sail-propelled vehicle comprising a movable base comprising a fin, at least one mast situated substantially on a longitudinal median axis of the vehicle and to which at least one sail support is attached comprising, on the one hand, an upper end fixed in a high point of the mast, and secondly, a lower end fixed near the movable base.
  • sails for example jibs or mainsails, whose particularity is to be stretched between, on the one hand at the front, a support of sail, and on the other hand a boom or, at the back one, or plays.
  • the sail support the support on which is supported, or is strained, or hung, or maintained, in one way or another the front side of the sail.
  • the tack of the sail and the lower point of the sail support are attached to the sailboat, in front and in the middle (ie in the plane of symmetry ) of the sailboat.
  • the sail support is often the forestay that serves as both a support on which the jib is straightened, and helps to maintain the mast in its place.
  • the sail carrier can also be the sail winder.
  • the sail support is the mast.
  • drift can be used indifferently to designate a drift or keel; this term may also be replaced by antidérive, thereafter.
  • the device according to the invention uses this method, by improving the existing devices.
  • a complementary device also reduces the torque moment due to the pressure of the water on the drift (when the vehicle is a sailboat).
  • the present invention relates to a sail-propelled vehicle comprising a movable base comprising at least one mast to which at least one straight sail support is connected comprising, on the one hand, an upper end attached to the top of the mast. and, on the other hand, a lower end fixed near the movable base and spaced from the median axis of the sailboat, on the downwind side, characterized in that this lower end of the sail carrier can be lowered relative to the hull of the boat, this lowering being adjustable.
  • the sail support may be, for example, a tensioned steel cable or any other high voltage resistant material or a rigid rod to make the sail support as straight as possible, with inevitably a slight curvature due to deformation materials under stress.
  • the sail support may also be a cable stretched inside a rigid cylinder; when the tension of the cable is released during the tacking, the cylinder avoids the cable and the sail to slump. It can also be a sail winder.
  • reference plane P1 the plane of the deck of the sailboat. If the boat does not have a bridge, such as a dinghy, this reference plane P1 may be the plane of the rim of the hull. Obviously, neither the deck of the sailboat nor the rim of the hull are really flat, but the plane P1 corresponds to a master plan.
  • the sailboat when the sailboat is in the rest position (without gite and classic position for the sail), it is, for a mainsail, the substantially horizontal plane at the deck, or the rim of the hull, to the place of the mast, and, for a jib or sail of the same type, of the plane substantially horizontal at the level of the deck or the rim of the hull, at the point of tack of the jib.
  • This plane P1 is related to the sailboat, and tilts with him when he sleeps on one side or the other.
  • the lower end of the sail carrier exits the outside of the hull (of the outer hull for a multihull) on the leeward side, and can be lowered relative to the hull of the sailboat, and even below the hull. level of the sailboat's bridge.
  • the sailboat is provided with a support carrying a rail whose carriage, to which is fixed the lower end of the sail carrier, can move along this rail, characterized in that the end of the rail comes out of the rail. outside the hull, and below the plane of the deck.
  • the support of the rail is movable to increase the offset to the outside and the lowering of the lower end of the sail support.
  • the support of the rail moves sliding itself on another rail (or slide) attached to the boat.
  • the rail moves because the support on which is mounted this rail is pivotable.
  • a part of the arm in particular the part of the arm exiting on the outside of the hull, can be folded by means of a hinge, or any other means, towards the interior of the sailboat and / or towards the front or the back (especially to reduce its size in the ports).
  • the lower end of the support of sail is moved by means of an arm.
  • the arm has an inner end fixed to the structure, generally near the longitudinal axis, by means of a hinge, allowing it, by pivoting, to move its other end, as well on one side as on the other. of the vehicle.
  • the other end of the arm carries the lower end of the sail carrier. The same arm can thus ensure the displacement of the lower end of the sail support from one edge to the other in the intermediate positions, and in particular in the conventional (central) position of the sail carrier.
  • the arm is composed of at least two bars articulated together, each of the bars being telescopic, and pivotable on itself.
  • the two bars can be deployed, according to their joints, remaining in a vertical plane, preferably for a mainsail, or in a horizontal plane, preferably for a jib. They can also be in an inclined plane. But they can also evolve in space outside of any plane, according to their articulations, and even more so if they rotate on themselves.
  • the sailboat has a rail attached to the structure of the boat.
  • this rail circulates a carriage on which can rest one of the bars making up the arm.
  • This rail can be transverse, circular or any other form, it is fixed for example, on the bridge. It can go outside the hull.
  • rail and carriage may equally well be replaced by a slide and slide, and generally denotes any device making it possible to move a part, the carriage or the slide, along another straight or curved longitudinal portion, the rail or the slide.
  • the sailboat has a stirrup (or lady) on each side, fixed on its structure, towards the outside of the sailboat.
  • This stirrup is intended to receive one of the bars making up the arm, to serve as a support and guide.
  • the arm when deploying from the classic or resting position, must pivot so that one of its arms reaches the caliper as soon as possible. At that moment, the arm is held in 2 points, the internal articulation point, and the stirrup.
  • the stirrup therefore provides better rigidity to the arm and sail support assembly.
  • the stirrup has a role similar to the trolley in its rail of which we have just spoken, the difference is that the carriage maintains and guides one of the bars of the arm, while the stirrup intervenes only in the second part of the deployment of the arm.
  • the first bar is held in two points, but we must still ensure the rigidity of the second.
  • Several devices may be suitable: a device for blocking the second arm on the first, in the extension of the first, or with a given angle, fixed or adjustable.
  • the stirrup, or the carriage can also serve to fulfill this role.
  • the boat has two arms, one on each side (unlike previous devices where the same arm was used to move the end of the sail support on one side or l other of the sailboat).
  • one end is fixed by a hinge to the structure of the sailboat, at a location located outwardly relative to the median axis of the sailboat.
  • structure also means the extensions of the structure, such as a support or amount, outside the shell, connected to the actual structure.
  • each of the two arms is provided with a clamp (or hook or other means of attachment) to hang the lower end of the sail carrier.
  • This lower end is worn sometimes by the clamp of one of the two arms, sometimes by the clamp of the other arm.
  • the second end of the two arms is joined in the plane of symmetry of the sailboat and the sail support is held by the two clamps of the two arms.
  • one of the clamps stops holding the sail support to let the other take it in its movement from the inside to the outside of the sailboat.
  • the arm can have several bars, which can be telescopic.
  • a float towards the end of the arm is a float, or a small hull.
  • This advantage is more specific to monohulls (a trimaran, for example, already has side hulls).
  • a float at the end of the arm provides additional stability and security, made more necessary because of this suppression or decrease in ballast.
  • the sail support is attached to a high point of the mast by means of a fixing at this high point, allowing the displacement of the sail carrier relative to this high point.
  • the mat may be shorter than the sail support, and the sail support is necessarily rigid.
  • the sail support is provided with a slide over a part of its length, and the mast is provided with an attachment point (fixed relative to the mast) sliding in the slide (this is the slide, attached to the sail carrier, which is movable), allowing the sail carrier to be movable while being held up there.
  • the sail support is connected to a high point of the mast by an arm, one end of which is connected to this high point of the mast by a hinge, and the other end, at one point of the sail support, by another articulation at this point.
  • the mat can be tilted. This makes it possible to increase the moment of counter-gite, and to increase the lift of the sail (that is to say the vertical component v of the force of the wind on the sail F).
  • the sail support spaced apart from the longitudinal median axis is associated with at least one listening passage for said sail.
  • the distance between the longitudinal central axis and said listening passage is greater than the spacing distance of the lower end of the sail support from the longitudinal center axis, and may be adjustable.
  • the height relative to the bridge, the listening passage can also be adjustable.
  • the listening passages can be mounted on one or more transverse arms, possibly adjustable in length and height with respect to the level of the bridge. All of the above mentioned means for moving the lower end of the sail carrier can be resumed to move the (or) listening passages.
  • the listening passage of the jib is worn (or linked) to the arm which already carries the mainsail support.
  • the sail is provided with a sail return, which is a piece of fabric, or any other material, connected along the lower edge of the sail and returning to the interior of the sailboat, serving to channel the air.
  • a sail return which is a piece of fabric, or any other material, connected along the lower edge of the sail and returning to the interior of the sailboat, serving to channel the air.
  • the wind creates a pressure on one side of the sail, and a depression on the other.
  • the air bypasses and passes from the side under pressure to the other side.
  • It is a kind of short circuit that significantly reduces the effectiveness of the lower part of the sail. This is even more true when the boat is in counter-gite, and / or when the sail is inclined in the opposite direction to the usual sense, because the air has a downward movement from the top of the sail, down.
  • the sail return is opposed to the short circuit, so that the air pressure on the sail is greater, the ducted air can escape only from the rear, and all this creates a effect that will be called "

  • the sailboat is provided with a pivoting anti-verve which is a surface fixed at the end of a support consisting of one or more arms, one end of which is fixed to the anti-drift, the other to the sailboat by means of a pivoting joint around a horizontal axis in the plane of symmetry of the sailboat, around which pivots the support by passing the anti-drift under the sailboat, from one edge to the other
  • the boat is provided with (at least) two pivoting anti-drift, one (or one on two) on each side of the sailboat, each pivoting about a horizontal axis parallel to the plane of symmetry of the boat.
  • the axis parallel to the plane of symmetry of the sailboat instead of being horizontal, is raised forwards, which gives the anti-drift a sustentation effect (or foil).
