Definitions

  • the invention relates to the field of snow gliding boards. More specifically, it relates to a method for manufacturing gliding boards, the upper face of which has relief effects with specific locations.
  • a gliding board has an upper face which is formed of an upper protective layer consisting of a plastic sheet.
  • the majority of gliding boards are made by molding, and the upper protective layer takes 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 upper face. This face may not be completely flat, but may include certain recesses.
  • the shape of the mold cover is then produced in a complementary manner.
  • this solution is ill-suited to cover boards for sliding, the upper face of which has recesses or concavities, since it is then necessary to use additional relief layers having a very specific geometry, complementary to the shape of the board.
  • additional relief layers having a very specific geometry, complementary to the shape of the board.
  • several additional layers of different relief are necessary to decline a range of boards in its different lengths.
  • ski board has also been proposed, the upper face of which has raised relief effects, comparable to the texture of a golf ball.
  • Such a ski is produced by using an upper protective layer which has been previously extradited on a printing calender.
  • This solution has the drawback of imposing certain particular operating constraints during molding, to avoid deforming, or even making disappear, the relief patterns initially produced 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 these are made directly on the upper protective layer .
  • certain areas of the plate are more advantageous to be covered with relief patterns than others. Mention may in particular be made of the upper edges of a ski which are frequently subjected to the friction of the edges of the other ski of the pair, or even other skis, in particular in the queues of the ski lifts. So when the top edges of the board have patterns in relief, the wounds generated by the edges are less visible.
  • An objective of the invention is to make it possible to produce relief effects on the upper face of a gliding board, while retaining the possibility of locating them in particular areas, and without making the production process too complicated.
  • the invention therefore relates to a method of manufacturing a board for gliding on snow, such as skiing, monoskiing 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, before molding, a sheet having relief effects is interposed between the upper protective layer and the mold cover, so that, during 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.
  • the relief effects are generated on the upper face of the board at the same time as the latter is molded, without therefore requiring any additional operation.
  • These relief effects are generated by the use of an additional element interposed between the mold cover and the upper protective layer, with all the possible geometry possibilities.
  • this sheet having the reliefs can be arranged either over the whole, or over only a fraction of the upper protective layer, so as to define reliefs either over the whole of the board, or even over well localized areas. It will be preferred in particular that these relief effects are arranged at least at the level of the upper edges of the board in order to partially mask the injuries generated when the skis come into contact with sharp objects, such as in particular the edges of other skis.
  • the sheet having the effects of relief can be perforated, and for example produced in the form of an openwork textile, of the fabric or grid type, so that the upper protective layer during molding penetrates the openings of this sheet to come into direct contact with the bottom of the mold.
  • the sheet comprising 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 gliding boards whose upper protective layer has reliefs shaped by deformation of the upper protective layer itself, these patterns being produced on only a fraction of its surface, and preferably at least at least. level of the upper edges of the board.
  • FIG. 1 is a summary perspective view of a ski produced in accordance with the invention, above which is shown the characteristic sheet making it possible to obtain the effects on the upper face of the board.
  • Figure 2 is a sectional view of the gliding board, shown before molding, between the bottom and the mold cover.
  • Figure 3 is a sectional view of the board shown after molding.
  • Figure 4 is a cross-sectional view of the board shown after removal of the sheet having the characteristic reliefs. Way of realizing the invention
  • the invention relates to a snow gliding board (1), which can be a ski, a monoski, a surfboard, or the like.
  • a board (1) as illustrated in FIG. 1, has an upper face (2), which in a characteristic area (3) has relief effects (4).
  • the board also includes a recess (5), located at the front level of the ski, and forming a relatively marked rung of thickness.
  • the relief effects (4) are present on a localized portion of the board, in particular at the level of the upper edges (6) of the board, which constitute zones sensitive to blows or to frictions made with sharp objects. such as the edges of other skis.
  • a sliding board is produced in a mold (12) comprising a bottom (13) and a cover (14).
  • the bottom of the mold (13) receives an assembly (15) comprising the edges (16) and a gliding sole (17).
  • the mold cover (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 produced by a woven fabric, the weft threads of which are spaced from one another to define openings (22).
  • the different textile threads are made of a material, or covered with a material, which is non-adhesive vis-à-vis the material of the upper protective layer.
  • the characteristic sheet (10) is removed, by a peeling operation, to obtain the structure illustrated in FIG. 4.
  • the raised areas (24) are therefore visible on the upper face of the board, especially at the edges (6) of the latter.
  • the characteristic sheet (10) can occupy only a part of the upper face of the board, but also cover it completely to define the characteristic reliefs over the entire surface of the board.
  • multiple textures can be adopted for the characteristic sheet (10) without it being perforated, as in the shapes illustrated in the figures. It may simply have relief effects obtained by embossing or on its underside.
  • the characteristic leaf shapes and therefore areas with reliefs can be modulated at will.
