Definitions

  • the invention relates to the field of sliding boards on snow. It is more specifically a method for manufacturing gliding boards whose upper face has relief effects with particular locations.
  • a gliding board has an upper face which is formed of a protective upper layer consisting of a plastic sheet.
  • the majority of gliding boards are molded, and the upper layer of protection adopts the shape of the mold cover during these operations.
  • the bottom of the mold cover is polished, so that the majority of existing boards have a smooth top face. This face may not be completely flat, but have some recesses.
  • the shape of the lid of the mold is then carried out in a complementary manner.
  • this solution is poorly adapted to cover sliding boards whose upper face has recesses or concavities, since it is then necessary to use additional relief layers having a very particular geometry, complementary to the shape of the board.
  • additional relief layers having a very particular geometry, complementary to the shape of the board.
  • several additional layers of different relief are needed to decline a range of boards in its different lengths.
  • ski board has also been proposed, the upper face of which has hollow relief effects similar to the texture of a golf ball.
  • a ski is made by employing a protective upper layer which has been previously extruded on a printer calender.
  • This solution has the disadvantage of imposing certain particular operating stresses during molding, to avoid deforming, or even to make disappear, the relief patterns initially made on the upper protective layer.
  • the use of such a sheet previously embossed or calendered requires that the entire upper face of the board has the same patterns, and that these patterns are arranged repeatedly on the board.
  • the upper protective layer undergoes certain deformations during molding, which cause distortion of the relief patterns when they are made directly on the upper layer of protection .
  • some areas of the board are more interesting to be covered with relief patterns than others. It may be mentioned in particular the upper edges of a ski that are frequently subjected to the friction of the edges of the other ski of the pair, or else other skis, especially in the queues of the lifts. So when the upper edges of the board have raised patterns, the injuries generated by the strokes are less visible.
  • An object of the invention is to make it possible to achieve relief effects on the upper face of a gliding board, while retaining the possibility of locating them in particular areas, and without complicating the production process too much.
  • the invention therefore relates to a method of manufacturing a snowboard on snow, such as skiing, monoski or surfing.
  • a board has an upper protective layer which is shaped by molding to form the upper face of the board.
  • this method is characterized in that , prior to molding, a sheet having relief effects is interposed between the upper protective layer and the mold cover, so that, during the molding, the layer upper protection of the board is deformed to adopt relief effects corresponding to those of said sheet, and in that after molding, said sheet is removed to reveal the reliefs formed on the upper face of the board.
  • this sheet having the reliefs may be disposed either on the entirety or only a fraction of the upper protective layer, so as to define reliefs either on the entire board, or on well-localized areas.
  • these relief effects are arranged at least at the upper edges of the board to partially mask the wounds generated during the contact of the skis with sharps, such as including the edges of other skis.
  • the sheet having the relief effects may be perforated, and for example made in the form of a lace fabric, of the fabric or grid type, so that the upper layer of protection during molding penetrates the openings of this sheet to come into direct contact with the bottom of the mold.
  • the sheet with the relief may also not be perforated, but simply embossed.
  • the upper protective layer adopts the embossing patterns present under the characteristic additional sheet.
  • Such a method therefore makes it possible to produce sliding boards whose upper protective layer has reliefs shaped by deformation of the upper protective layer itself, these patterns being made on a fraction only of its surface, and preferably at least at level of the upper edges of the board.
  • the invention relates to a board for gliding on snow (1), which can be a ski, a monoski, a surfboard, or the like.
  • a board (1) as illustrated in figure 1 , has an upper face (2), which in a characteristic zone (3) has relief effects (4).
  • the board also comprises a recess (5), located at the front level of the ski, and forming a relatively thick step of thickness.
  • the relief effects (4) are present on a localized portion of the board, in particular at the upper edges (6) of the board, which constitute areas sensitive to blows or rubs made with sharp objects. such as the edges of other skis.
  • a gliding board is made in a mold (12) having a bottom (13) and a cover (14).
  • the bottom of the mold (13) receives a set (15) comprising the edges (16) and a gliding sole (17).
  • the cover of the mold (14) receives the upper protective layer (20) which is itself covered by a sheet (10) in the areas in which it is desired to obtain reliefs.
  • the sheet (10) is made of a woven fabric, whose weft son are spaced from each other to define openings (22).
  • the different threads of the textile are made of a material, or covered with a material, non-adhesive vis-à-vis the material of the upper protective layer (20), and this to allow the peeling of the sheet (10). ) after molding.
  • the molding which combines effects of temperature and pressure, and which can for example implement an in-situ injection step of an expandable material, it is obtained as illustrated in FIG. figure 3 , a board whose upper protective layer (20) has deformed by penetrating the interstices (22) of the various son (21) of the sheet (10).
  • the portions (24) having penetrated these interstices (22) form raised protuberances (24). In some cases, depending on the operating conditions used, the protuberances (24) can come to the contact of the mold cover.
  • the characteristic sheet (10) is removed by a peeling operation to obtain the structure illustrated in FIG. figure 4 .
  • the raised areas (24) are therefore apparent on the upper face of the board, especially at the edges (6) of the latter.
  • the characteristic sheet (10) may occupy only a portion of the upper face of the board, but also cover it completely to define the characteristic reliefs on the entire surface of the board.
  • multiple textures can be adopted for the characteristic sheet (10) without it being perforated, as in the forms illustrated in the figures. It can simply have relief effects obtained by embossing or under its underside.
