Definitions

  • the invention relates to the field of winter sports. It aims more precisely a ski with a new shape allowing an improvement of its conduct, particularly with regard to the transmission of support.
  • the skier's shoe is held together with the board by a composite safety attachment a stop located at the front of the shoe, and a heel trapping the heel.
  • the bindings are located on the ski in a defined area standard known as "mounting area for fasteners". This area is centered relative to at the shoe mounting point corresponding to the middle of the shoe. Her length is between 30% and 50% of the carrying length of the ski in depending on the size of the ski.
  • skis have a very deep dimension line, and therefore have a relatively small width in the middle zone corresponding to the zone of mounting the binding.
  • the skier exerts forces essentially at the front of the binding. These supports, at the time of the impulse, are transmitted by the board to the snow at the edges, and more precisely on the edges located inside the turn.
  • the ski deforms, and more precisely bends mainly in flexion.
  • the ski retains its intrinsic characteristics of deformation even when fitted with safety bindings and the shoe of the skier.
  • the ability to deform the ski influences its behavior, that is to say its precision, its grip, its speed, its comfort .... It is directly related to the intensities and directions of the forces exerted on the ski by the skier.
  • the deformation of the ski depends on the internal structure of the ski and its geometry including its dimension line and its thickness variation, each ski being preferably designed for a specific range of use: long turn, short turn, powdery ....
  • This gliding board is characterized in that it has a height offset between the front portion of the mounting area of the binding, and the rear portion of the mounting area of the binding, so that the thickness of the gliding board in the front portion of the mounting area of the binding is greater than the thickness of the gliding board in the rear portion of the mounting area of the binding.
  • the invention consists in giving the gliding board a shape particular, in which the front part, on which the stop of the attachment, is raised relative to the rear part. This front part is separated from the rear part of the mounting area of the binding, by a difference of well marked level.
  • height offset we mean a difference of significant height, materialized by an equivalent slope of at least 20%.
  • This extra thickness is present in the ski area under load maximum, typically corresponding to the impulse forces at the front of the shoes in the range of 200 daN to 500 daN. It ensures a load distribution advantageous, better resistance to deformation of the ski and allows, in depending on the internal structure chosen, i.e. better amortization of vibrations, i.e. a more efficient transmission of forces to allow more great responsiveness of skiing.
  • This zone of greater thickness limits the deformations and in particular the bending of the ski in flexion at the level of the active part when the bend, which results in longer presses therefore more effective edges on the snow.
  • this extra thickness zone gives the board rigidity and additional stiffness, which results in a decrease in the capacity of the board to enter into oscillations, and therefore a gain in precision when triggered and driving the turn, in other words a strong attenuation of the phenomena of "grazing".
  • the difference in thicknesses of the board in the front and rear portions respectively of the mounting area of the fixing is between 3 and 30 mm.
  • the thickness of the board decreases continuously from the front of the front area of the binding mounting area, to the line contact before.
  • the ski profile has a gentle downward slope from the location of the fixing stop to the level of the contact before.
  • This embodiment is particularly advantageous for conform the internal reinforcement located below the upper face forming the decoration.
  • the portion behind the mounting area of the binding has a maximum thickness less than that of the front zone, which decreases in a gentle slope and without breaking up to the rear area of the ski or heel.
  • the raised area is also limited forward by a second step.
  • the gliding board has a boss formed on the top of the board, at the front of the binding mounting area, the extra area being delimited not only at the rear, but also at the front by recesses. At the front and at the rear of these recesses, the ski is similar to a traditional ski.
  • the front portion of the mounting area of the fixing having a greater thickness behind the mounting area of the fixing, extends over a length between 150 and 350 mm.
  • This outgrowth is, for the most part, at the front of the point materialized on the ski, as corresponding to the "shoe middle”.
  • the upper surface of the ski has a projection allowing stiffening of the ski in order to obtain the desired pressure distribution on snow.
  • the boss can extend transversely over all or part of the width of the gliding board.
  • this boss may consist of a single localized part substantially at the median level of the width of the board, or in several parts located at least at the edges of the board.
  • Figure 1 is a side view of a ski according to a first form of production.
  • Figure 2 is a side view of a ski according to a second form of production.
  • Figures 3, 4 and 5 are partial side views of skis made according to the invention, illustrating the recess at the rear of the boss according to the invention.
  • Figures 6 to 8 are summary cross-sectional views along VI-VI of FIG. 2 at the level of the characteristic boss of the skis produced according to three different embodiments.
  • Figure 9 is a top view of a ski produced according to a variant of execution.
  • Figure 10 is a partial top view, in the boss area characteristic, of the internal core of a ski produced according to another variant of the invention.
  • FIG. 11 is a side view of the core illustrated in FIG. 10.
  • FIG. 12 is a view in median longitudinal section of the core of the figure 10.
  • Figure 13 is a cross-sectional view of the core of Figure 10 along the XIII-XIII plan.
  • Figure 14 is a sectional view of Figure 10 along the plane XIV-XIV.
  • Figure 15 is a sectional view of Figure 10 along the plane XV-XV.
  • Figure 16 is a sectional view of Figure 10 along the plane XVI-XVI.
  • a board of slide (1) includes a spatula end (9) at the front, an end at the rear heel (7), a front contact line (11) and a rear contact line (14), and a mounting mounting area (2) defined in a standardized manner.
  • This mounting area of the binding (2) is divided into two parts separated by a "shoe middle" mark (19), namely a front portion (3) intended to receive the stop of the fixing, and a rear portion (4) intended to receive the heel of a binding.
  • this area for mounting the fasteners has a recess between the front portion (3) of the mounting area of the attachment (2), and the rear portion (4) of this same area (2).
  • This particular shape gives the gliding board in the front portion (3) of the mounting area of the binding, a thickness (e 1 ) significantly greater than the thickness (e 2 ) measured in the rear portion (4) of the mounting area of the binding (2).
  • a height offset (6) materializing the rear limit of the boss (5).
  • the difference in thickness of the ski between the front portion (3) and the rear portion of the mounting area (2) of the binding can be between 3 and 30 mm, and preferably in the vicinity of 10 mm.
  • the area (3) located under the stop of the fixing corresponding to the area of application of the skier's impulse force at the time when starting and driving the turn is thicker and therefore ensures localized stiffening of the ski.
  • the rear of this area has a classic thickness because less loaded in this turn phase.
  • the heel piece is mounted, either on a raising wedge, either on a platform itself secured to the boss (5), and extending rearward.
  • the thickness of the rear part of the ski will therefore conventionally be decreasing by example of a thickness of 18 mm at the rear mounting area of the binding up to a thickness of 7 mm at the heel end (7) of the ski.
  • Figure 3 defines the specific height offset of the invention.
  • the specific ski of the invention has a relatively height difference brutal, located in the mounting area of the binding, practically at the level of the middle of shoe area (19).
  • This step having a height H and a length L has a slope H / L greater than 20% (twenty percent).
  • the profile of the step (6) can be extremely varied, as for example illustrated in Figures 4 and 5.
  • the recess (6) limiting the rear of the boss (5) can consist of an inclined face (10), whose inclination relative to the upper surface (8) of the rear area for mounting the ski bindings can be optimized according to the internal structure of the board.
  • the board can include in its structure internal, an insert (15) intended to facilitate the attachment of the fixing screws, or a possible raising platform, as well as increasing the value of the tightening torque liable to cause deterioration of the screw thread or its thread.
  • This insert (15) may consist of a plate of various materials, such as for example laminates impregnated with phenolic or melamine resin, acrylonitrile butadiene styrene (ABS) plates, or even glass fiber laminate combined with epoxy resin.
  • ABS acrylonitrile butadiene styrene
  • Such an insert (15) is of planar geometry, which means, as can be visualize in figure 4, that its distance to the upper face of the board is variable. More specifically, this distance is greater in the boss area (3), while it is relatively reduced in region (4), corresponding to the area thinner board.
  • Such an insert (15) may have a length close to 550 mm, a width of 55 mm, and a thickness of the order of 1 to 2 mm.
  • the gliding board according to the invention has a greater thickness in the front part of the mounting area of the binding.
  • the boss (5) having an additional thickness can extend, as illustrated in figure 1, to the front of the ski, with a continuous decrease the thickness of the ski along the boss (5).
  • the boss (17) has a reduced length, and limited at the front by a second recess (18). In other words, the boss (17) is located on a fraction only of the front of the ski binding mounting area.
  • this boss typically, the length of this boss is between 150 and 350 mm.
  • the boss (17) as illustrated in FIG. 2 can be present on all or part of the width of the ski.
  • this boss (17) is present over the entire width of the ski.
  • the boss (20) extends transversely only over a central part of the width of the ski.
  • This boss (20) can be adapted according to the desired stiffness characteristics, as well as the position in which the fixing stop.
  • this boss is breaks down into two bosses (26, 27) extending from the lateral zones of the ski towards the median plane.
  • the ski has a hollow area (29), the width of which can be variable over the length of the boss.
  • the boss (30) is present over the entire width of the board at the front of the mounting area fixing. It extends forward to form a rib (31), the width and the height decreases by moving in the direction of the spatula.
  • Figures 10 to 16 illustrate the inner core of a ski produced according to a variant embodiment of the invention.
  • the ski comprises a core (50), which is characterized in that it comprises a zone (52) for mounting the binding consisting of two portions, namely a rear portion (54) of smaller thickness, and a front portion (53) of greater thickness, these two portions being separated by a recess (56).
  • the front portion (53) is extended by an even thicker zone (58) extending over a few tens of centimeters beyond the position of the fixing stop.
  • edges of the board include exposed portions (60) of the core, which are laterally flush.
  • the core (50) is laterally visible at the level of the skate area, and is covered by the upper protective layer of the shell of the ski, in front of the skating area.
  • the height of the apparent edge (60) of the core decreases progressively in the junction zone (61) between the skate and the front of the ski.
  • the element forming the visible side part (60) of the core can be made of multiple materials, for example resin laminates phenolic, melamine resin, or even thermoplastics such as than acrylonitrile butadiene styrene (ABS).
  • resin laminates phenolic, melamine resin, or even thermoplastics such as than acrylonitrile butadiene styrene (ABS).
  • the upper face of the core includes a recess (65) intended to receive a local reinforcement in the form of a leaf.
  • This sheet may in particular consist of a glass fiber fabric impregnated with epoxy resin.
  • this local reinforcement and therefore the recess corresponding, may have an elongated shape formed by the association of two mainly rectangular zones, namely a first front zone (66), covering approximately 80% of the width of the core, and a rear zone (67), covering the almost the entire width of the core.
  • the rear zone (67) of this local reinforcement extends over almost the entire zone mounting fixture, and can end, for example, with a zone triangular (68) or even by any other advantageous form to improve the resistance of the gliding board.
  • the local reinforcement, and therefore the corresponding recess (67) is bordered laterally by the presence of the portions (60) forming the visible edges, so that when the reinforcement is in place in the recess, its upper surface is at the same level as the top of the elements of visible edges, and that the core therefore has a section rectangular.
  • the board and the core have a zone (58) in excess thickness, which has one end rear (68) of curved shape.
  • This extra thickness (58) is extended laterally and backwards by two ribs (69) observable in FIGS. 10 and 14. These ribs are susceptible frame the front end of a plate or platform intended to receive the fixing itself.
  • the gliding board according to the invention has a particular geometry ensuring in particular a very good transmission of support during the initiation of turns.
  • the structure of the board allows heightening of the fixing stop without intermediate piece.
