Definitions

  • the invention relates to a hollow gliding board.
  • Gliding boards are generally solid objects, even when it comes to floats which must have a weight / volume ratio lower than that of water.
  • a composite manufacturing technology in which the board has an inner core which is formed of a light material and which is covered with a rigid external material giving the board its shape and rigidity.
  • Such boards are in principle much lighter than traditional boards, which has many advantages, and which allows in particular to adopt a style of driving the board much more lively. With this new driving style. the user is leads to request a new type of dynamic behavior of the board.
  • the invention provides a hollow gliding board comprising a shell external which delimits at least one internal cavity, characterized in that it comprises at least a flyweight of inertia.
  • the invention will be more particularly described in the context of a surf float for seas, but it can be used for other hollow boards.
  • a board 10 whose shell delimits an internal cavity 11 which extends over almost the entire length and almost the entire width of the board.
  • a board 10 can for example be constructed in assembling two half-shells 12, 14 to each other by gluing.
  • Each half-shell 12, 14 is for example formed from a sandwich material comprising two outer skins 16. each composed of layers of fiber fabrics impregnated with thermosetting resin, both skins 16 framing a core 18 of very light material such as foam or a material Honeycomb.
  • Each half-shell has a thickness of the order of a centimeter and is shaped in a mold to take the shape, respectively, of the deck 12 and the hull 14 of the float.
  • the two half-shells are assembled by a glue joint along their plane joint 20 which follows the peripheral edge of the board.
  • the board as well constructed may include at least one stiffener, in particular a longitudinal stiffener 22 produced in the form of a vertical partition which extends into the cavity 11 along the axis longitudinal center of the board by connecting the two half-shells 12, 14 to each other.
  • a board 10 constructed according to this principle is for example described in document US-3,514,798.
  • a hollow construction allows to go from a weight of about 3kg to a weight of about 2 kg for a surfboard of the same shape and having mechanical characteristics equivalent or higher.
  • This weight gain which can be greater than 30%, allows radically change the behavior of the board on water, and is reflected in particular by greater speed and greater liveliness of the board.
  • FIG. 2 the possibility of having a counterweight 24 in an area has been illustrated. located near the rear end of the board, this area can go up to the support area of the surfer's back foot. By placing a flyweight in this area, the board gains stability but will tend to lose speed
  • the possibility of having a counterweight 24 has been illustrated in the area which corresponds to the support area of the front foot of the surfer.
  • This zone corresponds substantially to the area of the center of gravity of the board.
  • the weight will be of a weight less than 200 grams, preferably between 100 and 150 grams.
  • the board is slightly less lively than a board without counterweight, which may facilitate the control of the board under certain conditions.
  • the additional weight, and therefore of inertia allows the board to keep speed more easily at the end maneuver.
  • FIG. 4 Another possibility, shown in Figure 4, is to have a flywheel 24 slender spread over at least part of the length of each of the edges of the board.
  • the counterweight 24 can thus extend over the entire periphery of the board.
  • the overall mass of the weights thus distributed must remain relatively low, and it will therefore be advantageous to use a foam bead as a counterweight.
  • the counterweight 24 can consist of a fixed block of material on one of the faces of the internal cavity 11.
  • the material used may be a dense material, for example a block of resin, in which case the counterweight 24 will be small, and the addition of mass will then be perfectly concentrated, both in its horizontal positioning in the plane of the board only in the vertical direction in the thickness direction of the board.
  • the counterweight may be made of a sparse material such as a block of foam, to which in this case the weight will be larger.
  • the flyweight does not make the connection in height between the deck and the hull, and it is therefore possible to fix it either on the side of the deck 12, or on the side of the hull 14 (as illustrated). Of course, the choice of such or such positioning will affect the behavior of the board.
  • the counterweight 24 extends over the entire height of internal cavity and it can form, in addition to its role of modifying the inertia of the board, a reinforcement between the deck 12 and the hull 14 to limit the appearance of sinking.
  • the material used will preferably be a foam or honeycomb material. Such an embodiment will for example be used for thinner boards, or when the counterweight 24 is placed in an area thin board, as for example in the case of embodiments of Figures 2 and 5.
  • the board is of the type comprising a longitudinal stiffener internal 22, and the flyweights 24 are arranged in the vicinity of the floats, as in the exemplary embodiments of FIGS. 1 and 4.
  • the counterweight can for example be carried out with a rigid foam block cut to an appropriate shape, or it can be a foam block which is allowed to expand inside the board when the two are assembled half-shells 12, 14.
  • the counterweight 24 is directly integrated into the structure of one of the half-hulls.
  • the half-shell has a sandwich structure and the flyweight 24 is integrated into the core 18, between the two skins 16 of the sandwich.
  • the counterweight 24 can for example be formed from a sheet of dense material, possibly a metallic foil.
  • the flyweight is located on the inner side of the core which is closest to the cavity 11.
  • the counterweight is arranged on the outer side of the core, or that the counterweight extends over the entire thickness between the two skins 16.
  • such a construction can be provided both on the hull 14 and on the deck 12, and the counterweight 24 can be arranged transversely in the center or on the contrary on the sides of the board.
  • the counterweight according to the invention should not be confused with a reinforcement and a classic stiffener, from which it stands out, in addition to its function, by its positioning and its weight which as a rule will not exceed 200 grams.
  • the gliding board thus proposed is therefore original, in particular in that the invention allows you to significantly modify the behavior of a hollow board, keeping a very large part of the intrinsic qualities due to the lightness of these hollow planks.
