Definitions

  • the present invention relates to a competition ski, more particularly intended for the practice of special slalom.
  • the runner has to pass through doors very close to each other at high speed and each bounded by two pegs of the same color.
  • This exercise requires great qualities of dynamism, judgment and reactivity.
  • One of the major difficulties consists in not straddling the internal stake at the turn while printing at the end of the tip of the internal ski, a path passing as close as possible to the stake. Any trajectory error leads irreparably to the fall and the elimination of the runner.
  • Document DE-A-41 01 915 relates to a ski comprising a reinforced tip of the spatula. At least one of the lateral sides of the endpiece is bordered by a reinforcement projecting with respect to at least one of the faces defining the thickness of the spatula.
  • the object of the invention is to remedy this drawback by proposing an asymmetrical tip of new shape and design.
  • the ski provided with such a part remains in contact with the snow, creating only a slight lateral displacement without consequence.
  • the safety margin for the runner increases further and promotes performance.
  • the subject of the invention is a piste ski for the practice of slalom, comprising a supporting central downstream part, ending in a front contact line, beyond which extends, in the area of the tip, a part upstream raised on which an asymmetrical spatula tip is attached which extends it by a central part having the general shape of a horn the end of which is situated on a longitudinal axis offset inwards with respect to the median longitudinal axis of the ski.
  • the end piece comprises a cantilevered side part connecting to the central part and constituting a skirt on the side of the outer edge of the ski and the upper surface of which is intended to come into contact with the stake.
  • the skirt is formed in such a way that the normal measured at any point on the upper surface of the latter forms a positive, non-zero angle with a plane parallel to the ground when the ski is tilted towards the outside by an angle between 15 and 45 ° approximately when taking the edge.
  • any impact of the skirt on the stake induces a reaction force whose vertical component is directed downwards; which keeps the end of the ski in permanent contact with the snow.
  • FIG. 1 illustrates the front of a left ski of the prior art using a traditional asymmetrical tip.
  • the ski (1) comprises a central downstream part (10) constituting the bearing zone and a raised upstream part (11) partially constituting the tip zone (2).
  • the upstream part (11) is continuously extended by an end piece (3) of asymmetrical shape whose profile is slightly curved upwards.
  • the end piece comprises an upper (30) and lower (31) surface having the general shape of a horn and which are connected to each other by an external edge (33) curved cord C1 and a curved inner edge (32) of cord C2 smaller than C1.
  • the edges (32, 33) meet at the end (34) of the end piece located on an axis (II, II ') which is offset inwards (INT) relative to the median longitudinal axis (I , I ') skiing.
  • the advantage of such a construction is that it makes it possible, as shown in FIG. 3, to increase the safety distance by shifting the end (34) of the spatula inwards to favor the passage of the stake ( 24).
  • the ski is in an external edge grip and is inclined towards the inside of the turn by a certain angle ( ⁇ ) generally between 15 and 45 °.
  • the impact takes place at a point (35) located on the outer edge (33) and, more particularly, near the edge lower (330) connecting the outer edge (33) to the lower surface (31) of the end piece, due to the upward curving of the end piece.
  • the force F of the ski is directed towards the outside (EXT or towards the inside of the turn) and down.
  • the reaction R therefore induces a vertical component R1 directed upwards and which therefore tends to lift the end of the ski and cause it to lose its grip with the snow. This phenomenon is all the more accentuated, that in dynamic behavior, the stake bends slightly during the passage of the ski and slides along the lower edge (330) creating a ramp effect which progressively takes off the end of the ski.
  • FIG. 4 illustrates the front of a ski (left) (1) according to the invention which also comprises a central downstream part (10) constituting the bearing zone and a substantially raised upstream part (11) constituting, at least in part , the spatula (2); the two parts being limited to each other by a contact line (12).
  • a tip (3) is attached to the upstream part (11) and extends it.
  • the end piece (3) comprises a first central part (4) formed by an upper (40) and lower (41) surface having the general shape of a horn.
  • the upper (40) and lower (41) surfaces are connected by an internal edge (32) of curved shape on the inside of the ski and meets at the front by an end (34) located on a longitudinal axis (II, II ') offset inwards (INT or outside the turn) with respect to the median longitudinal axis (I, I') of the ski.
  • the central part (4) is connected to a second cantilevered side part constituting a skirt and extending the upper (40) and lower (41) surfaces.
  • the two parts (4) and (5) may be limited by a more or less sharp upper edge (6), as shown. However, it is in the spirit of the invention to provide for a gradual transition from one part to the other through a substantially rounded and more aesthetic area.
  • the skirt (5) is formed in such a way that the normal identified at any point on its upper surface (50) forms a positive angle ( ⁇ ), not zero, with a plane (P) parallel to the ground (S) when the ski is inclined outwards by a certain angle ( ⁇ ) more particularly between 15 and 45 °,
  • ⁇ the angle
  • the point of impact (35) located on the upper surface (50) of the skirt (5).
  • the vertical result (R1) of the reaction force (R) of the stake whose point of application is an impact point (35) which can be located anywhere on the upper surface (50) is directed downwards , thus tending to flatten the ski and more particularly the outer edge (7) on the snow.
  • the point of application (35) of the stake on the tip moves along the upper surface (50) when the ski advances, which imparts a bending of the stake forward but the resultant (R1 ) always stays down.
  • the ramp effect thus plays on the upper surface (50) of the skirt (5) to release the end of the ski from the stake while maintaining perfect grip of the edge (7) on the snow.
  • the cutting of the side part or skirt (5) can be scalable but it is advantageously possible to provide a greater width towards the front of the end piece then a progressive reduction towards the rear so that the lateral edges of the end piece are connected substantially continuously with the side edges of the ski.
  • FIG. 8 illustrates an example of how the end piece (3) is attached to the upstream part (11) of the ski.
  • the end of this part is provided with lateral notches (13, 14) and takes position in a housing (36) of a shape complementary to that of the end piece (3) comprising lateral bosses (360, 361).
  • the end piece can be made of elastic deformable material such as a flexible plastic material or of elastomer to allow a force fitting, for example.
  • elastic deformable material such as a flexible plastic material or of elastomer to allow a force fitting, for example.
  • provision can be made of plastic material loaded with short glass fibers or the like.
  • Figures 9 and 10 illustrate another embodiment in which the end of the upstream part (11) is truncated and ends with a transverse edge (15).
  • the central part (4) can be produced without housing and its lower surface (41) is fixed by any means such as screwing, gluing or riveting to the upper surface (110) of the upstream part (11) of the ski.
  • This particular case has the advantage of being able to lighten the end of the ski by providing an end piece of material with a density less than the average density of the ski, for example.
  • FIG. 11 illustrates a variant in which the skirt (5) comprises reinforcing ribs (52) connecting the lower surface (51) of the skirt to the lower surface (41) of the central part (4).
  • the tip can be integrated into the structure of the ski during its production, by molding, for example.
