Definitions

  • the present invention relates to skis used in winter sports, and intended to slide on snow and ice.
  • the skis generally used have a lower sliding face connecting to two lateral faces along two lower edges provided with metal edges, the lateral faces connecting to an upper face.
  • the skis have a relatively small width compared to their length, their anterior end being curved upwards to form a spatula.
  • the thickness of the ski is generally greater in the central part than in the front and rear parts of the ski.
  • the width of the lower face of the ski is smaller in the central part than in the rear and front parts, the width being maximum in the front part of the ski, that is to say at the neighborhood of the spatula.
  • the upper face of the ski is generally a ruled surface, that is to say defined by the longitudinal displacement of a straight transverse line parallel to the lower face of the ski.
  • the cross section of the ski is generally a rectangle or a trapezoid, the large opposite sides of the rectangle or the trapezium being formed by the lower face and the upper face of the ski, the small opposite sides of the rectangle or the trapezoid being formed by the side faces of the ski.
  • the greater thickness of the ski in the central zone gives this central zone increased rigidity.
  • This central zone is also intended to receive the bindings for the adaptation of a user's shoe.
  • the front and rear areas of the ski which have a reduced thickness, are more flexible and elastically deform when the ski is used. If one wishes to make a ski having good flexibility in the anterior and posterior zones, it is therefore necessary to provide such anterior and posterior zones having a reduced thickness.
  • a first problem encountered in traditional ski structures is that the central zone of the ski, which has a relatively large thickness to give it great rigidity, causes a fairly appreciable increase in the weight of the ski.
  • a second problem encountered in known ski structures is that the necessary thickness of the ski, to obtain sufficient mechanical strength, leads to having ski side faces having a relatively large height. This relatively large height of the lateral faces gives the ski a relatively heavy appearance, and constitutes a lateral bearing surface of large surface opposing the lateral penetration of the ski into the snow, thus slowing the lateral movements of the ski when cornering or in skid.
  • the central part of the ski has a relatively reduced width compared to the end parts of the ski, so that the ski boot adapted to the bindings in the central zone of the ski generally extends on both sides of the ski.
  • the edge of the boot inside the turn is brought closer to the ground and tends to touch it, which risks slowing down the progression. of the skier and disturb the effectiveness of the support on edges.
  • Document FR-A-2 565 836 relates to a one-piece ski structure which comprises a reinforced box with biconvex profile supported on a pair of edges. Such a shape makes the structure sensitive to various stresses (flexion, torsion, vertical compression, microdeformations ).
  • the present invention proposes to remedy the aforementioned drawbacks by the design of a new form of ski.
  • the shape of the ski is progressive as a function of the longitudinal portion considered along the ski, and this progressive shape is such that the ski can be given an increased real height while decreasing the height of the edges or side faces of the ski, giving in skiing the appearance of a thinner ski, and favoring the lateral penetration of the ski in the snow.
  • the progressive shape of the ski according to the invention is such that the end regions of the ski can be given increased flexibility simultaneously without excessively reducing the height of the edges of the ski in said end zones, so as to maintain resistance. sufficient mechanics of the part supporting the lower edges of the ski.
  • the ski structure according to the invention has the effect of raising the boot support zone relative to the lower sliding surface of the ski, favoring the release of the boot sole from the ground when driving the turns, without increasing the volume and weight of the ski compared to a traditional structure with rectangular or trapezoidal section.
  • ski properties of increased mechanical resistance in bending in the central zone, and / or properties of increased mechanical resistance in torsion over the entire length of the ski without increasing the volume and the weight of the ski compared to a traditional structure with rectangular or trapezoidal section.
  • the ski comprises, over most of its length, an upper blade of mechanical resistance arranged in the vicinity of the upper face of the ski in its median zone close to the vertical longitudinal median plane of the ski, so that the distance between the said upper blade and the plane of the neutral horizontal fibers of the ski varies as a function of the mean radius RM of the upper face of the ski, and the said blade is thus further from the plane of the neutral fibers in the zones with a small mean radius RM, and is closer to the plane of the neutral fibers in the zones with a larger medium radius RM.
  • the ski comprises a box structure, formed of a central core surrounded by a tubular element of mechanical resistance, the tubular element having an external surface close to the external surface of the ski and substantially parallel to this, so that the cross section of the tubular element is rounded to follow the convex shape of the upper face of the ski, giving the tubular element better torsional rigidity.
  • the ski according to the invention comprises a lower sliding face 1 connecting to two lateral faces 2 and 3 according to two respective lower edges 4 and 5 provided with metal edges.
  • the lateral faces 2 and 3 are connected to an upper face 6.
  • the front end of the ski is bent upwards to form a spatula 7.
  • the rear end of the ski is slightly bent upwards to form the heel 8.
  • the ski may in particular comprise a tip tip 7 and a heel protector 8, fixed by any means such as snap-fastening, bonding or the like.
  • the lateral faces 2 and 3 of the ski in the embodiment shown in FIGS. 3 to 5, are inclined relative to the perpendicular to the lower face 1 of the ski, at a substantially constant angle A.
  • the side faces 2 and 3 of the ski are substantially perpendicular to the underside 1.
  • the angle A can be greater in the vicinity of the ends of the ski, on the sections AA of FIG. 3 or CC of FIG. 5, than in the central zone of the ski on the section BB of FIG. 4.
  • the lateral faces 2 and 3 of the ski are connected to the upper face 6 by upper lateral edges 9 and 10 with rounded cross section of radius RL.
  • the radius RL advantageously has a value less than 6 millimeters.
  • the upper face 6 of the ski according to the invention has, in cross section, over at least the greatest part of the length of the ski, a convex shape, for example rounded.
  • This convex cross-sectional shape of the upper face 6 of the ski is an upper line, the central part of which forms an apex and the two ends of which are inclined at an angle of less than about 60 degrees relative to the lower face of the ski.
  • Said upper line has a shape identical to or slightly different from a circle, that is to say that it deviates relatively little from the circle passing through said vertex and said ends.
  • Said circle which most closely approximates the convex cross-sectional shape of the upper face of the ski has a radius called the average radius RM of cross-section.
  • the average radius RM of cross section varies as a function of the longitudinal position of cross section considered along the ski.
  • the values that the average radius RM takes in the central zone of the ski are lower than the values that the average radius RM takes in at least one of the front or rear end zones of the ski.
  • the convex cross-sectional shape of the upper ski face is substantially identical to a circle, that is to say that its curvature is substantially constant over the entire width of the cross section. This embodiment confers a certain regularity on the upper surface.
  • the invention also applies to other convex shapes of cross section of the upper face.
  • it must be avoided that the curvature of the lateral zones of the upper face is too great, because it then approaches a rectangle, and the advantages of the invention are lost.
  • an upper face of the ski the cross section of which is a polygonal line close to the circle of average radius RM, for example a line with three segments, with a central segment substantially parallel to the underside of the ski and two inclined lateral segments. .
  • said convex shape of cross section of the upper ski face must remain little different from a circle passing through its central part and its ends.
  • the values which the average radius RM takes in the central zone of the ski, represented in FIG. 4 are less than the values of said average radius RM in the anterior end zone of the ski, represented in FIG. 3, and are smaller than the values taken by said mean radius RM in the rear end region of the ski, represented in FIG. 5.
  • the maximum average radius REA in the anterior end zone of the ski is advantageously greater than the maximum average radius REP in the rear end region of the ski.
  • the maximum average radius REA in the anterior end region of the ski is less than the maximum average radius REP in the rear region of the ski.
  • the ski bindings intended to secure a ski boot on the upper face 6 of the ski, are generally arranged in the central area of the ski or a little behind the middle of the ski in the area shown in FIGS. 1 and 2 between the cross sections FF and GG.
  • the bindings are fixed on the upper face of the ski in longitudinal positions which can differ from one case to another, and which lie in an area between 40 and 60 cm in length.
  • the mean radius RM of cross section it is advantageously possible to provide for the mean radius RM of cross section to keep a substantially constant value RC throughout the central area lying between the planes FF and GG. Bindings can thus be provided, the lower support face of which is shaped to apply exactly to the upper ski face, whatever the longitudinal position in the central zone intended to receive the bindings.
  • FIG. 9 illustrates the variations in average radius RM, or curvature, of the cross section of the upper face of the ski as a function of the longitudinal position of the cross section considered.
  • the curve 20 represents the transverse profile of the upper ski face in the central area of the ski. In this central zone, the curvature is constant, and, to follow the variations in width of the ski, the curve stops at the ends 21 and 22 in the narrowest part of the ski, and extends to the ends 23 and 24 in the cross sections of the central ski part closer to the ends of the ski.
  • the curve 30 represents the transverse profile of the upper ski face in the heel area.
  • Curve 40 represents the transverse profile of the upper ski face in the tip region.
  • the mean radius RM of the upper face 6 of the ski varies continuously as a function of the longitudinal position of transverse section considered along the ski, from the value RC in the central area of the ski, up to maximum REA and REP in the anterior and posterior ski areas.
  • the average radius RM of the upper ski face varies as a function of the longitudinal position of the cross section considered, because to obtain the desired flexibility, the thickness of the ski must decrease the closer you get to the ends. And, as the ski widens at the same time, the upper face 6 must be flattened more and more in a progressive manner, to avoid reducing the height of the edges too much in the vicinity of the ends. As a result, it is advantageous to continuously increase the value of the average radius RM when one approaches the ends.
  • the ski according to the present invention makes it possible to increase the height H1 or distance of the sole of the shoe relative to the ground, and makes it possible simultaneously to decrease the height H2 of the edges or lateral faces 2 and 3 of the ski.
  • the internal structure of the ski comprises an upper blade of mechanical strength 11, of thickness E1 and of width B1, disposed near the upper face 6 of the ski.
  • the upper blade of mechanical strength 11 has the effect of giving the ski sufficient rigidity to correctly oppose the flexing of the ski in the longitudinal direction.
  • the ski reacts like a beam and forms an arc, the fibers located towards the inside of the arc tending to shorten, the fibers located towards the outside of the arc tending to lengthen , and one can define a mean plane 12 containing the neutral fibers, that is to say the fibers whose length is not significantly modified during bending.
  • the stiffening effect obtained by the upper blade of mechanical strength 11 naturally depends on the thickness E1 and the width B1 of the blade, as well as on the nature of the material used to form this blade, but also depends very significantly on the average distance 0.5 x (Y1 + Z1) between this strip 11 and the plane 12 of the neutral fibers.
  • the rigidity obtained is thus greatly increased when the distance Y1 between said blade 11 and the plane 12 of the neutral fibers is increased.
  • the convex shape of the upper face 6 of the ski makes it possible to arrange the upper blade of mechanical resistance 11 at an average distance 0.5 x (Y1 + Z1) greater than the average distance 0, 5 x (Y + Z) possible in a structure with rectangular section as shown in FIG. 6. Thanks to this increase in distance, the invention makes it possible to significantly reduce the thickness E1 and the width B1, and therefore the volume and the weight of the upper blade of mechanical strength 11 for equivalent performance compared to a traditional structure with rectangular section of thickness E and width B. It is possible, for example, to provide an upper blade of mechanical strength 11 whose width B1 is less than the width B of the blade required in a traditional structure with rectangular section, for the same thicknesses E1 and E. It follows that the total weight of the ski according to the present invention can be less than the weight of a traditional ski with rectangular or trapezoidal section.
  • the particular shape of the ski according to the invention is used to increase its torsional rigidity.
  • the ski comprises a box structure, formed of a central core 13 surrounded by a tubular element 14 of mechanical strength.
  • the tubular element 14 has an outer surface which is close to the outer surface of the ski and substantially parallel thereto, or which can constitute the outer surface of the ski itself.
  • the cross section of the tubular element is convex, for example rounded convex at least in the portion corresponding to the upper face 6 of the ski, so that the general section of the tubular element approaches a section circular, giving the tubular element better torsional rigidity.
