Definitions

  • the invention relates to the field of sliding sports, and more precisely alpine skis. It relates more particularly to the Alpine ski family of small, with a relatively deep dimension line.
  • the current trend is towards improving ease, that is to say maneuverability and comfort, particularly by saving weight. This can be obtained by reducing the length of the skis. So, for ten years, the average length of a slalom ski has decreased by more than 30 cm from one average size greater than 2 m, to reach today a size close to 1.70 m. Most of the size reduction has taken place in all last years.
  • the width of the tip area of a ski slalom increased from around 85mm to 102mm, which represents a twenty percent (20%) increase, most of which occurred during last few years.
  • the turns are more and more "cut", that is to say that the skids at the back of the ski at the end of a turn are progressively reduced, and very often non-existent.
  • the cornering is carried out preferably on the edge which provides a gain in precision and speed. More precisely, the tendency to widen the dimension line is measured by increasing the difference between the width of the spatula area and the width of the skate area.
  • a first problem which the invention proposes to solve is that the transverse stability of a relatively short ski, when it is flat on snow and at high speed.
  • a second problem which the invention proposes to solve is that of the attachment, and therefore the bending and torsional rigidity of a short ski, in particular in its front and rear areas, so as to ensure sufficient pressure at the edge level when driving cut corners.
  • the invention aims to simultaneously solve these two problems by proposing a short ski whose grip is greatly improved at high speed, whether when it is on the edge by increasing the pressure of the front and rear ends of the ski, or when it is in direct track by controlling transverse friction.
  • This ski also has at least one groove of stiffening in the lower part, parallel to the longitudinal plane median, said groove embedding the sole and the lower reinforcement in a additional deformation to form a rib on said reinforcing element, improving its flexural stiffness characteristics.
  • the ski according to the invention incorporates at the level of its sole, one or more grooves which both provide longitudinal guidance when the ski is in direct trace, and which gives the lower reinforcement element a rigidity which is more particularly effective in increasing the pressure on the edges when driving the turn.
  • the ski has at least one groove which is produced by deformation of the lower elements, namely the sole and the lower reinforcement which covers.
  • the ski is allowed to resist transverse movements when it is flat on the snow, and thanks to the same grooving means, we provides rigidity that allows better transmission of support at the squares.
  • the ski of the invention is characterized in that it also has two sets of grooves stiffening (21-23, 24-26) formed in the lower part, parallel to the median longitudinal plane (5), these grooves (21-26) embedding the sole (6) and the reinforcement in a complementary deformation to form a rib (12) in said reinforcing element, improving its flexural stiffness characteristics, a first set of grooves (21-23) being located at the heel area, and a second set of grooves (24-26) being present at the spatula area, and in which inside each set, the grooves (22, 25), located at near the median longitudinal plane, have a length greater than that grooves (21-23, 24-26) closest to the edges (7).
  • the grooves are present only in the tip or heel areas, while the skate area does not contain any any.
  • the grooves present in the heel zone and the spatula zone may be collinear, of so as to be arranged in alignment with one another, or else offset.
  • the shape of the grooves can have an advantageous profile. So in a preferred shape, the grooves have a width greater than 5 mm which can range up to 15 mm and a depth greater than 2 mm up to 8 mm.
  • the grooves have a circular arc section, which ensures a good channeling of snow at the level of the sole.
  • their front and rear ends are progressive so as to impose only weak ruptures of slopes with internal reinforcements.
  • the invention relates to a ski (1) for short adults (L), typically less than 180 cm.
  • the ski (1) breaks down, longitudinally, in three contiguous zones, know a first spatula zone (2), located at the front, a skid zone (3) on which will be fitted with safety bindings, and a heel area (4), at the rear of the skate area (3).
  • the skis in accordance with the invention belong to the family of skis whose tip area (2) has a maximum width (L 1 ) of between 100 and 140 mm.
  • the skate area (3) of the ski has a minimum width (L 2 ), between 60 and 100 mm.
  • the skis according to the invention include, but are not limited to the only family of so-called “parabolic” skis, intended for known practice according to the English expression of "carving”.
  • skis shorter than those used in the past, have a very wide dimension line in-ground making it possible to make very marked turns on the edge, that is to say with the minimum slip.
  • such a ski (1) has, seen in section, a sole (6) intended to come into contact with snow, and forming the sliding surface.
  • This sole (6) is laterally bordered by metal edges (7, 8) intended to bite into the snow during turns.
  • This sole (6), as illustrated in FIG. 2, is covered with an element of reinforcement (9) present over a large part of the width of the ski.
  • This reinforcing element (9) can be of various constitution, and can for example be a metallic reinforcement made of steel or aluminum alloy. It can also be a fibrous reinforcement, and incorporate glass, kevlar® or carbon fibers.
  • This ski has at least a groove (10) formed in the sole (6), parallel to the longitudinal plane median (5).
  • This groove (10) present in the sole (6) is produced by deformation lower elements of the ski, namely the sole (6) and the reinforcement element (9).
  • the reinforcing element (9) disposed above the sole (6) has also a groove (11) forming a chute inside which is embedded the rib (10) of the sole.
  • the trough (11) of the reinforcing element forms a rib (12) stiffening in flexion the reinforcing element (9).
  • the sole (6) has two grooves (10, 15) arranged along the median longitudinal plane (5) of the ski, and separated by a flat sole zone (16), at the level of the shoe zone (3).
  • the grooves (10, 15) present at the front and at the rear of the sole are located in the same alignment, but the different grooves could be offset relative to each other.
  • the ski according to the invention comprises grooves (21-26) which are associated by a set of parallel grooves.
  • the external grooves (21, 23, 24, 26) are in particular intended to reinforce skiing near the edges (7, 8).
  • the grooves (22, 25) located near the median longitudinal plane (5) have a length greater than that of the grooves (21, 23, 24, 26) closer to the edges (7, 8).
  • the geometry of the groove (10) can adopt a preferential profile.
  • profiles as softened as possible, while not excluding not, in some places there are sudden breaks in slopes.
  • the ski illustrated in FIG. 2 has a groove whose profile is a half ellipse, width between 5 and 15 mm, and depth between 2 and 8 mm.
  • the longitudinal ends of the grooves have a profile in gradual gentle slope, limiting the deformations of the internal reinforcements.
