Definitions

  • this spatula which is defined as the area beyond the forward contact line, has an increased length compared to traditional skis.
  • the front and rear contact lines are defined in a standardized way, as the most forward and rearward points beyond which the ski is no longer in contact with the plane on which it rests, when it is loaded. at its midpoint.
  • skis designed specifically for the practice of "free ride” are not really suitable for the practice of "free style” and vice versa.
  • skiers wish to practice skiing both "free ride” and “free style”, depending on snow conditions in particular.
  • skiers who engage in these activities evolve according to these two practices and therefore need to have two different pairs of skis, which they selectively use depending on the snow conditions.
  • the invention thus relates to the family of skis called "bi-spatulate", comprising elongate spatulas. More precisely, these skis therefore comprise a slipper zone defined between the front contact line and the rear contact line beyond which the spatulas respectively front and rear are defined. The lengths of these spatulas, measured up to the ends respectively front and rear are typically greater than 250 millimeters. Likewise, these two-spatula skis have a region of maximum width situated between the front or rear contact line and the corresponding end.
  • the radius of the side line at the middle of the pad can be chosen less than 20 meters, and preferably close to 18 meters.
  • the camber of the pad can be chosen greater than 2 mm, and typically close to 5 mm.
  • spatulas of great length are preferred, and typically greater than 450 mm for the front spatulas and 350 mm for the rear spatulas. More specifically, it has been found that the ability to trigger turns and to drive them in powder snow, in a "free ride" type of development, is facilitated when the ratio between the maximum width of the front spatula divided by the maximum width of the rear spatula is greater than 1.03, and preferably greater than 1.05 or 1.07.
  • the directionality of the pad, and therefore its skiability on groomed track is improved when the ratio between the width measured at the level of the line of front contact divided by the width at the rear contact line is greater than 1.03, and preferably greater than 1.05 or 1.07.
  • the maximum width of the front spatula is greater than 110 mm, is preferably between 115 and 150 mm, preferably between 118 and 128 mm.
  • the figure 1 illustrates a ski according to the invention which comprises a pad area (1) on which are mounted the elements of the safety binding (4, 5).
  • This pad area is delimited at the front by the front contact line (L CAR ) defined in a standardized manner.
  • This characteristic line is determined when the ski is loaded while resting on a horizontal plane and is defined as the foremost point where the gliding sole is in contact with this plane.
  • the symmetrical definition applies for the rear contact line (L CAR ).
  • the ski has a front spatula (2).
  • the rear spatula (3) corresponds to the portion of the ski located behind the rear contact line.
  • spatulas of the skis according to the invention have a long length, typically greater than 250 or even 500 mm, which gives them an ability to evolve in deep snow.
  • this width (I CAV ) is between 90 and 120 mm, and preferably between 95 and 110 mm.
  • the width of the board ( MC ) at the midpoint of the ski is between 80 and 120 mm, and preferably between 85 and 100 mm.
  • This maximum width is at a distance of between 150 and 270 mm, and preferably in the vicinity of 260 mm in front of the front contact line.
  • the rear spatula (3) On the other side of the board, the rear spatula (3) has a maximum width (I MAR ) of the order of 114 to 123 mm, which is less than the maximum width of the front spatula (l MAV ). This maximum width is at a distance of between 40 and 170 mm, preferably close to 155 mm behind the rear contact line.
  • the surface of the front spatula (2) is greater than that of the rear spatula (3), which gives a directional behavior to the board for the evolution in deep snow.
  • the pad (1) has on the contrary a substantially symmetrical geometry between the front and the rear, which facilitates the evolutions in both directions of sliding, for the realization of figures on packed snow.
  • the second example of embodiment illustrated in figure 4 has a pad (1) of asymmetrical geometry.
  • the width ( CAV ) at the front contact line (L CAV ) is greater than the width (I CAR ) at the rear contact line.
  • the pad is therefore wider at the front than at the rear, which facilitates, like a traditional ski, the handling and steering of turns and in particular the end of turn skid, on groomed snow.
  • the length of the pad measured between the front and rear contact lines is of the order of 98 to 108 mm.
  • the width at the level of the front contact line can vary between 120 mm and 130 mm, depending on the declination of the models in a given range, it being understood that this width at the front contact is greater than the width at the rear contact line which is of the order of 115 to 125mm, and of about 5% lower.
  • skis according to the invention have, according to the choice of dimensional parameters, the ability to make figures on groomed tracks while being particularly well adapted for the evolution in powder snow according to a practice of "free ride ".
  • the invention also makes it possible for a ski that is globally directional on snow-groomed snow to evolve in both directions for practicing powder snow.
