Definitions

  • the present invention relates to a float element, such as a windsurfing board, and its manufacturing process.
  • the float element forming a windsurf board according to the invention is of a type essentially consisting of two parts advantageously obtained by the techniques of injection of thermoplastic material, one of the parts forming the bottom, the other forming the cover, and said two parts being joined along a peripheral junction line by gluing, welding or the like.
  • a float element such as a windsurfing board, consisting essentially of two parts, one forming a bottom, the other forming a cover, joined along a peripheral junction line by gluing, welding or the like, in accordance with the invention, is characterized in that to facilitate the operations of joining said two parts, there is provided inside the float, sandwiched between the bottom and the cover, a filling known per se, light, such as expanded plastic foam, in which there are housed, at least in places, reinforced parts forming "anvils" which are engaged between said bottom and said cover substantially opposite various zones distributed in the vicinity of said peripheral junction line and bearing between said zones and opposite opposite parts of said bottom.
  • the float element such as a windsurfing board, consisting essentially of two parts, one forming a bottom, the other forming a cover, joined along a peripheral junction line by gluing, welding or the like, of the type comprising said bottom and said cover a light filling such as an expanded plastic foam
  • the junction is carried out along said peripheral line, on top of the float, set back from the outer outer perimeter line of the float (usually forming a waterline), the bottom comprising for this purpose an upper edge projecting a few centimeters towards the center of the float above said perimeter line, providing in said upper edge around the entire peripheral junction a groove or recessed groove in which engages and is received the peripheral edge of said cover so that the junction of the bottom and the cover is made on the e above the float without protruding protrusion from the junction bead or the like.
  • the float thus produced therefore has a perimeter edge devoid of welds giving the float better rigidity.
  • the surface appearance of the board is improved and gives more comfort to the user.
  • reinforced parts forming "anvils” are engaged between said bottom and said cover substantially facing various zones distributed in the road. tiling of said peripheral junction line and bearing between said zones and opposite opposite parts of said bottom. The assembly of the two parts of the float is thus improved, which increases the strength of the board and reduces manufacturing defects.
  • the cover comprises a substantially central rib which projects under it and comes into the assembly position to rest against the middle part facing the bottom.
  • a float element forming a windsurf board essentially consists of a first part 1 forming a bottom on which is assembled a second part forming a cover 2.
  • the assembly of the bottom 1 and the cover 2 (forming a bridge) is carried out along a peripheral junction line 3 (see FIG. 5) on the top of the float, in re line of the exterior exterior perimeter line 5 of the float.
  • the bottom has an upper edge 6 projecting a few centimeters towards the center of the float over the perimeter line 5 (forming the outer edge of the float) while providing in said upper edge all around the peripheral junction periphery.
  • a recessed groove or groove 7 more particularly visible in FIGS. 1, 2, 3 and 6.
  • peripheral groove 7 engages and is received the peripheral edge 8 of the cover 2, so that the junction of the bottom and the cover is made on top of the float without protruding protrusion of junction beads or the like (see Figures 1 and 6).
  • the cover 2 comprises a substantially central rib 10 projecting under it and coming in the assembly position to rest against the middle part opposite the bottom 1 (FIG. 3).
  • rib 10 In the rib 10, are formed at least two housings 11, 12 formed by local openings of this rib for the fin shaft and the housing of the mast foot of the board.
  • blocks of expanded plastic foam such as blocks of expanded polystyrene 13, 14.
  • reinforced parts such as wooden slats, of rigid plastic material or the like, are held in place in the foam filling as illustrated in 15, 16 (FIGS. 2 and 3), these slats being engaged between the bottom and the cover substantially facing opposite areas. parts in the vicinity of the junction line 3 and bearing between these zones and opposite opposite parts of the bottom.
  • Locking ribs (not shown) can be provided locally on the inner wall of the bottom where the slats 15, 16 will come to bear.
  • the assembly of the two parts thus obtained can be carried out easily by welding or gluing.
  • the provision of the central rib 10 and the filling blocks 13, 14 reinforced by the slats 15, 16 makes it possible to apply the assembly pressures necessary to obtain a good junction, and this without unfavorable deformation of the parts to be assembled.
  • this can be achieved by the so-called mirror technique consisting of softening by preheating the zones 6, 8 to be welded and then, when the desired softening temperature is reached, applying the two parts to assemble firmly against each other.
  • a braid or a conductive coating for example a metallic coating 20, 21 (see FIGS. 2, 3 and 6) along the junction lines and to pass an electric current either directly or by induction to obtain the heating and the fusion. desired local areas to be welded.
  • the assembly can be obtained by gluing using appropriate glues placed along the junction lines.
