Definitions

  • the invention relates to a sliding board intended to operate on snow or on ice, in particular, a ski of the alpine type, a monoski or else a snowboard.
  • the invention relates more precisely to the improvement of the sliding surface of such a board by the realization of a particular structuring and the methods making it possible to achieve such an improved structuring.
  • One of the aims of the present invention is to adapt the structure of the sole to the practice of new glides, in particular for snowboarding, but also for skiing when it is practiced on very varied terrains. as in deep snow and in powder or on poorly groomed tracks (skis widened in tip and heel and narrowed in skate thus conferring a dimension line in very pronounced wasp size).
  • the principle is generally, to seek to reduce the directive effect of the ski by not breaking the film of water in a unidirectional manner but in a multidirectional manner so as not to favor any direction.
  • the board becomes more mobile and manageable by being able to slide in all directions over 360 °.
  • the invention relates to a gliding board for evolution on snow, characterized in that it comprises a sliding sole on which are distributed several imprints of cells whose outline is a closed convex curve.
  • the outline of the cavities of the cells has a shape of a circle, an ellipse or an ovoid shape.
  • the cavities of the cells have a shape of a spherical portion or of a portion of ellipsoid of revolution.
  • the imprints can be obtained by thermoforming the sole during the assembly cycle of the various constituents of the board; by providing shaped bosses in the mold cavity.
  • Figure 1 is a bottom view of a snowboard.
  • Figure 2 is a sectional view of a cavity imprint executed in the sole.
  • Figure 3 is a simplified view of an embodiment of the invention.
  • Figure 4 is a view of another embodiment of the invention.
  • Figure 5 is a bottom view of a south according to a variant.
  • the snowboard 1 shown in Figure 1 consists of an elongated body in a preferred direction II 'with a sliding sole 2 and side edges 3 bordering the sides of the sliding sole.
  • the sole generally consists of high or low molecular weight polyethylene.
  • the soles with high molecular weight have longer molecular chains therefore more solid and which allow a better absorption of the waxes.
  • the sole has generally a thickness varying from 0.4 to 2 mm and is glued to the rest of the structure of the board.
  • the invention therefore consists in providing for the production of indentations or recesses in the form of concave cells 4 in the thickness of the sliding sole 2.
  • the contour of the cells forming part of the plane of the sole is that of a curve at any point convex and closed without sharp angles so as not to favor, or at least to privilege in a particular direction.
  • the distribution and the number and size of cells can be variable depending on whether one wishes to promote the desired effect at such or such a place on the board or on the contrary limit this effect.
  • the number of cells is between 6 and 200.
  • the distribution can be uniform over the entire surface of the board or, on the contrary, be concentrated in certain areas such as in the area of the bindings where the pressure is maximum.
  • the imprints have the shape of a spherical portion of radius R depending on the depth e between 0.2 and 3 mm.
  • the diameter D of the imprint is between 2 and 60 mm.
  • the spherical shape leads, thanks to perfect symmetry, to not favor any particular direction of the orientation of the imprint.
  • the interruption of the water film therefore takes place indifferently during a displacement in the direction II 'and during a sliding displacement perpendicular to II' or in a direction more or less inclined relative to I-I ', by example.
  • Another advantage is the improvement of the grip when taking the edge to execute a turn. This is a surprising effect which has been observed in numerous tests carried out and which finds two additional explanations.
  • the surface in contact with the snow when the surf or the ski is in edge grip becomes smaller than in the absence of a cell. As a result, the pressure is concentrated on the edge essentially; from which it results in better attachment.
  • FIG. 3 illustrates a way of making the imprints according to the invention by a thermoforming technique in a mold.
  • the components of the board are therefore stacked such as the core 10, the lower 11 and upper 12 reinforcements based on epoxy resin prepregs as well as the decoration top 13 and the polyethylene sole 2 in an assembly mold 5.
  • Des bonding films can be interposed between the elements if necessary.
  • the part of the mold 5 in contact with the sole comprises bosses in the form of spherical portions obtained by machining during the manufacture of the mold cavity.
  • the mold is closed and a baking cycle is applied at a determined temperature, at a given pressure and a determined time to obtain the assembly of the components together by crosslinking the resin of the reinforcements and the thermofusion of the bonding films. .
  • a baking cycle is applied at a determined temperature, at a given pressure and a determined time to obtain the assembly of the components together by crosslinking the resin of the reinforcements and the thermofusion of the bonding films.
  • the ski or snowboard After leaving the mold, the ski or snowboard must then undergo the traditional finishing operations; namely deburring, grinding, belt sanding, etc.
  • Figure 4 illustrates an alternative embodiment of the imprints.
  • the sole 2 in the form of a strip is driven and guided by a drive and guide device formed by cylinders 70, 71, 72 and strip 73.
  • a rotary tool 8 comprising bosses 80 distributed uniformly over its contact surface with the sole, hot prints the shape of the imprints in the sole material.
  • the tool can advantageously consist of a cylinder regulated at the polyethylene forming temperature of the sole, ie around 160 ° C. More precisely, the contour can take the form of a circle (perfect symmetry), an ellipse (two axes of symmetry orthogonal) or any ovoid shape (zero or an axis of symmetry only).
  • Another alternative embodiment also consists in machining recesses of the cavities of the cells after manufacture of the gliding board. Using a cutter having a suitable convex shape, the impressions are hollowed out to the desired dimensions in the sole.
  • FIG. 5 illustrates a variant in which the cells have an elliptical contour with a first axis of symmetry oriented in the longitudinal direction of the board and a second axis of symmetry perpendicular to the first axis of symmetry.
