Definitions

  • the invention relates to the approval of light skiffs with a single mast and in particular windsurfers.
  • the sail is completed by an auxiliary deflecting sail in the shape of a flattened triangle, the lower and upper corners of which are connected to the foot and the head of the mast, respectively by a tack and a halyard while the shank carries a fixed eyelet at the end of a support extending the boom or the boom beyond the point of attachment of the latter on the mast.
  • the sail is threaded on the mast thanks to an attached sheath formed by a strip of canvas whose two longitudinal marginal zones are applied and sewn respectively on the two faces of the sail over the entire height of the edge of the latter turned towards the mast.
  • sheath will designate either a sheath without a continuity solution or a sheath in two parts.
  • a first object of the invention is to provide that the sheath has an inside perimeter significantly larger than the outside perimeter of the mast and that it is stretched by a filling filling made of semi-flexible foam of synthetic material to closed cells with a tapered corner section which, opposite the point, follows the profile of the mast.
  • the upper tubular section which extends over substantially half the height of the mast can be fitted into a base cons formed at the user's discretion, by a single section of tube of larger section or by the interlocking assembly of two sections of tube having substantially the same length, the lower section having a smaller section to be fitted to the inside the other which then forms the central section and the most rigid part of the mast.
  • the greater flexibility of the lower section compared to that of the middle section makes it possible to improve the "defense" in gale.
  • the tubular sections have an oval section whose major axis is located in the plane of the sail.
  • at least one of the sections is reinforced by a median internal partition perpendicular to the major axis or by a soft friction drive, at the level of the maximum force, of a round reinforcing tube.
  • another object of the invention provides that the mast is pre-arched to present a curvature in the same direction as that of the sleeve but with a radius greater than that of the latter.
  • the rigging comprises an auxiliary deflecting sail, the point of which is then fixed on the end of a rigid support extending the boom or the whiskey
  • this support consists of a folded rod M-shaped with elongated legs, the re-entrant central point being intended to receive the eyelet of the point of the deflecting sail and the two legs which can be elastically separated and having their free ends bent inwardly to cooperate respectively with two footings or two holes made on the boom or the boom on either side of its point of attachment to the mast.
  • This assembly allows the displacement of the auxiliary sail from one to the other of the legs of the M, thus organizing in the vicinity of the mast, between this auxiliary sail and the sheath of the main sail, whatever the force "taken” by the wind, a “split effect” which prevents the detachment of the air streams from the upper surface of the main sail, which favors the flow of the relative wind during the large drop edges.
  • a triangular sail 10 is provided along its mast edge with a sheath 11 formed by an oblong strip, and the longitudinal marginal zones are applied and sewn on the two faces respectively of said edge.
  • the sail is intended for a windsurfing board and the sheath 11 is in two parts: ies extending on either side of a notch 12 situated at the level of the attachment point of the board boom on the mast.
  • the internal perimeter of the sleeve 11 is significantly larger than the external perimeter of the mast 13 on which it is to be threaded and the walls of the sleeve are stretched by a filling pad 14 of closed cell synthetic foam having a wedge-shaped section with a point 15 tapered.
  • this trim is sectioned into sections, four in the example shown. This arrangement improves the aerodynamics of the sail and, moreover, makes the mast unsinkable, which makes it easier to lift when it has been accidentally laid down on the water and prevents overturning in the case of a catamaran for example. .
  • the width of the scabbard is not limited, that the latter can be very large and that, at the limit, it is possible to design a double-thickness sail entirely quilted with a synthetic foam lining provided, of course, to give suitable shapes to each section of the lining and to provide a bellows at the notch 12 in the case of a sailboard.
  • the mast 13 is constituted in a known manner by nested tubular sections, namely an upper section 13a which extends over substantially half of the total height of the mast and a lower section 13b.
  • an upper section 13a which extends over substantially half of the total height of the mast and a lower section 13b.
  • the section of the tubular sections constituting the mast is an oval whose major axis is substantially in the plane of the sail ( Figure 2).
  • a reinforcement either by a median internal partition 16 perpendicular to the major axis (shown in lines mixed in Figure 2), either by gently introducing one or more sections of round tube.
  • the mast 13 can be pre-bent, as shown in FIGS. 1 and 3.
  • the camber of the mast at rest must have a radius of curvature slightly greater than that of the scabbard. This pre-arch decreases the force exerted on the angles of the sail when the tack tack 25 (FIG. 5) is stretched, which makes it possible to lighten the conventional reinforcements by extra thicknesses and reduce the pleating of the sail.
  • the sail 10 threaded on the mast is sometimes associated with an auxiliary deflecting sail 17 (FIGS. 4 and 5) in the shape of a flattened triangle, the lower and upper corners of which are connected to the foot and to the head. -from the mast, respectively by a tack 18 and a halyard 19, while the recess carries an eyelet 20 fixed to the end of a support 21 extending the boom or the boom beyond the point of attachment of this last on the mast.
  • Such rigging is represented felt in FIGS. 4 and 5 on a windsurf board 22, conventionally with a mast foot 23 and a wishbone 24.
  • the user must be able to pass from port side to starboard or vice versa without letting go of the wishbone and the support 21 must be relatively short (about 35 to 40 cm) so that its end passes in front of the user's chest when the latter holds, with his arms extended in front of him., both branches of the wishbone, but when it comes to any other light skiff, the length of the support can be arbitrary.
  • the support 21 has the general shape of an M with elongated legs.
  • the re-entrant angle of the M is intended to receive the eyelet 20 of the auxiliary sail and the legs can be spaced apart elastically so as to bring their free ends, bent inward, to engage in holes or in the recesses provided for in 26a , 26b on the nozzle 27 for fixing the wishbone 24 on the mast 13.
  • This arrangement allows the travel of the auxiliary sail from one leg to the other of the M, which organizes at 29 between the auxiliary sail 17 and the sheath 11 a slitting effect preventing the detachment of the air streams from the upper surface of the sail 10.
  • the invention provides for a soft friction fitting of the mast on the mast foot drum and a locking by elastic stapling, the elastic staple being constituted by a stirrup, the ends of the branches of which are curved inwards, each engage in two combined radial perforations of the mast and the reel, the transverse part of which comprises a loop used as the attachment point for the tack stretching the sail.
  • a means for locking the mast of a windsurfing board is shown in FIGS. 6 and 7.
  • a traditional mast foot has an articulation 30 of molded rubber having the shape of a hyperboloid of revolution limited by two straight sections in each of which is embedded a flush metal plate 31, respectively 32, carrying a central threaded axis 33, respectively 34, projecting outwards.
  • the axis 34 of the bottom plate 32 is screwed or the like ment fixed in a base 35 (shown schematically in broken lines) which fits and is immobilized firmly by a suitable means in a well 36 formed in a windsurfing board 37.
  • an intermediate piece 38 of molded synthetic material which comprises a base 38a surmounted in its center by an oblong cylindrical part 38b.
  • the diameter of the base 38a is substantially equal to that of the plate 31.
  • a drum 39 made of synthetic material which is provided at its lower part with an overflowing flange 40 and is retained in position longitudinal by a pin 41 diametrically crossing the part 38b just above its upper face.
  • the clip (FIGS. 1 and 2) is constituted by a stirrup 42 whose branches 43 and 44 can deviate elastically from one another and whose free ends 43a and 44a are bent at right angles inwards to cooperate with conjugated perforations 45a, 46a, respectively 45b, 46b, formed respectively through the walls of the mast 50 (perforations 45a, 45b) and the walls of the drum 39 (perforations 46a, 46b).
  • the stirrup 42 ( Figure 2) has on its transverse part a loop 48.
  • This loop 48 increases the elasticity when the branches 43 and 44 are separated.
  • the loop 48 constitutes a mooring point for the tack (not shown) used to tow the sail.
  • the tearing off of the stirrup 42 makes it possible to separate the mast from its foot and to slide the sheath of the sail along the mast without having any knot or other attachment to undo.
  • the tearing of the stirrup 42 results in the separation of the rigging from the board, the mast is released practically alone from the scabbard by gravity and sinks, and the "windsurfer" then has the sail which, if it has a foam lining as it is said above, can play the role of a buoy. rescue.
  • the sail 10 ( Figure 1) can have an edge circle along the fall 28 and then be battened.
