Definitions

  • the present invention relates to a drift device, intended to be used in a fluid with respect to which it is in relative motion.
  • this device can be mobile in a fluid at rest, or on the contrary be immobile in a fluid flow.
  • the fluid can be a liquid or a gas.
  • the device according to the invention can be placed under a hull, which floats on water. It can be, for example a fin, a keel, a rudder, a fin, or a rudder, fitted to the hull of a boat, a canoe, a windsurfing board, or the like. for example, it may be the fin fitted to a sail board intended for jumping, and comprising a single fin.
  • the present invention aims to avoid these drawbacks, by providing a drift device capable of automatically adapting to the conditions of use to obtain an optimum result.
  • a drift device comprises a rigid profiled fin, oriented in a plane substantially perpendicular to the plane direction defined by the waterline of the hull, and it is characterized in that part of the surface of the rigid fin is constituted by an elastically deformable flap around at least one theoretical axis substantially perpendicular to the water plane.
  • the flap is formed by a die blade material - formable, whose front is secured to the rigid fin.
  • the flap consists of a blade of rigid material, the front of which is connected to the rigid fin by deformable means with automatic elastic return.
  • the front of the flap is articulated on the rear of the rigid fin, by a hinge pin.
  • the elastic return means are constituted by a block of elastically deformable material, welded or glued both on the rear of the fin and on the front of the flap.
  • the elastic return means consist of one or more tension springs, bearing on the wing and on the flap.
  • the elastic return means consist of one or more elastic tensioners made of rubber or the like, bearing on the fin and on the flap.
  • a windsurfing board the hull 1 comprises, in the known manner, a fin fin on which are defined a leading edge and a trailing edge.
  • the fin 2 has in its rear part, corresponding to the trailing edge 3, a cutout 4, in which a flap 5 can move.
  • the latter can be produced according to various construction methods, to allow its deformation in the cutout 4, when it is subjected to a transverse force (that is to say perpendicular to the sheet of paper). On the contrary, when such a transverse force ceases, the flap 5 automatically returns to its rest position, that is to say to that in which it is in the same plane as the rest of the fin 2.
  • the flap 5 is itself made of a rigid material, and it is articulated on two sections of screw axis 6 and 7, which are therefore removable.
  • the front edge 8 of the flap 5 is integral with an elastic cushion 9, to which it is fixed by welding or by gluing
  • the front of this cushion 9 is fitted between two raised rods 10. which equate the rear fin 2 at this location.
  • the pivoting of the flap 5 around the geometric axis 11 that define the sections 6 and 7 ( Figure 3., double arrow 2) is only possible by elastic deformation of the cushion rubber 9.
  • a transverse force such as 13 or 14.
  • the flap 5 automatically returns to the same plane as the fin 2.
  • the geometric axis 11 is substantially perpendicular to the plane direction defined by the waterline of the hull 1.
  • the flap 5 is directly glued or welded to the elastic cushion 15, which is made of rubber or plastic.
  • This cushion is, in turn, welded or glued on the rear of the fin 2.
  • the hinge pin 11 is no longer materialized in this variant by sections of axis 6 and 7;
  • elastic tensioners such as 16 are placed on either side of the trailing edge 17 of the flap 5, stretched between the corresponding parts of the fin 2. As before, the latter has an axis hinge 11, for the front of the flap 5.
  • the flap 5 is connected by deformable elastic blocks 18, at the rear of the fin 2.
  • the flap 5 is articulated on the axis 11 around which it is resiliently recalled by a spiral metal spring 19, or by compression springs 20, which bear on the rear of the fin 2.
  • this device considerably improves the characteristics of navigation and use, in particular for a sailing dinghy, or for a windsurfing board. It can also be used on water ski fins, surfboards, or those of a device sliding on snow.
  • the axis 11 is not necessarily close to the perpendicular to the direction of the seed 22 of the fin 2.
  • the theoretical axis 11 is practically parallel to the leading edge 23 of the fin 2.
  • This variant corresponds for example the drift provided under the sole of a water ski.
