Definitions

  • the invention relates to a ski which is intended to slide on snow and ice.
  • a ski can be used in particular for the practice of alpine skiing.
  • the invention also relates more generally to any board intended to slide on snow such as for example surfing, monoski, etc.
  • Skis of this type which are currently known are generally in the form of an elongated beam, the front end of which is raised to form the tip. They include a lower sliding face, or sole, as well as an upper face. These two faces are connected together by two lateral edges. Usually metal edges are also located at the junction between the side edges and the lower surface. Usually, the binding elements are assembled on the upper surface of the ski, in its central zone.
  • Recent skis are made according to one or the other of two conventional composite structures, a sandwich structure or a box structure.
  • a ski having a sandwich structure is for example described in patent FR 1,124,600 ( Figures 1 and 2).
  • Such a ski has a central core, which is made for example from a fibrous or cellular material.
  • the core is coated above and below by two upper and lower reinforcing walls.
  • skis with a sandwich structure are versatile skis, the handling of which is easy and tolerant.
  • such skis have the disadvantage of not having high qualities of lateral attachment in turns and slopes.
  • a ski with a box structure is described in particular in patent No. 1,124,600 (FIG. 3).
  • a ski has a core, which can be made of fibrous or cellular material.
  • the core is coated on its upper surface, its lower surface and its lateral faces by reinforcing walls which constitute a box.
  • Such a structure gives the ski greater torsional rigidity. Compared to a ski with a sandwich structure, such a ski has higher grip qualities. However, such skis are less easy and less tolerant in driving than skis with a sandwich structure. Such box structure skis are not the best suited for inexperienced skiers.
  • One of the aims of the invention is to provide a ski which has both easy and tolerant driving, and excellent grip qualities on slopes or in turns.
  • Another object of the present invention is to provide a ski which is more economical to produce than a ski with a traditional box structure.
  • the ski according to the present invention is intended for the practice of sliding on snow. It includes a longitudinal beam with a raised front end to form the tip, a sliding sole and side edges. It is characterized by the fact that it has over a part of its length a box-type structure with a central core surrounded by an upper reinforcement wall, two lateral reinforcement walls and a lower reinforcement wall, and on another part of its length, distinct from the first part, a sandwich type structure, with a central core, an upper reinforcement wall and a lower reinforcement wall.
  • Figure 1 shows a side view of a ski according to a first embodiment of the invention.
  • FIG. 2 is a top view of the ski shown in FIG. 1.
  • Figure 3 is a sectional view of a cross section of the ski along line AA.
  • Figure 4 is a similar view at the line BB.
  • Figure 5 is a similar view at the line CC.
  • FIG. 6 shows in plan the upper reinforcement wall and the two lateral reinforcement walls according to a first embodiment of the invention.
  • Figure 7 shows a top view of the lower reinforcing wall.
  • Figures 8 and 9 correspond to variants of construction of the ski in its central area.
  • FIGS. 10a and 10b show an alternative embodiment of the upper reinforcement wall and of the lateral reinforcement walls.
  • Figures 11 and 12 are cross-sectional views of the skate area of a ski, and illustrate relative arrangements of the two elements shown in Figures 10a and 10b.
  • Figure 13 is an alternative embodiment of the element shown in Figure 10b.
  • Figure 14 shows a top view of a ski according to another implementation of the invention.
  • Figures 15 to 17 show different cross sections of the ski of Figure 14, respectively at the lines DD, EE, FF.
  • the ski 1 represented in FIGS. 1 and 2 generally represents the shape of an elongated beam in a longitudinal direction, the front end 2 of which is raised to form the tip.
  • the ski 1 has a lower surface or sole 3, which is bordered laterally by two edges 4 and 5.
  • the ski 1 also has an upper surface 6, and two lateral edges 7 and 8 which connect the upper surface 6 to the sole 3, or more exactly to the edges 4 and 5.
  • a central zone of the ski has been identified at 10 in FIG. 2. It is in this area that the binding elements are assembled, and that the boot rests on the ski. It is also in this area that most of the support that the ski exerts on its sliding surface is concentrated.
  • the ski In front of the central zone 10, the ski has a front zone 11, and behind, a rear zone 12.
  • the ski 1 therefore has three zones 10, 11 and 12.
  • the ski 1 has a box structure in at least one of the zones 10, 11, 12, and a sandwich structure in the remaining zone or zones.
  • the ski has a box structure at least in the central zone 10.
  • the ski has in the central zone 10 a box structure, and in the zones 11 and 12, that is to say towards the ends, a structure sandwich.
  • FIGS. 3 to 5 represent cross sections of the ski 1 respectively at the level of the cutting lines BB, AA, CC, which are located in the zones 10, 11 and 12.
  • the ski has a central core 15, which extends over substantially its entire length.
  • the core 15 is of any suitable type, it is made in particular of a fibrous material, such as wood, or strips of wood glued together, or any other known structure, for example a honeycomb structure.
  • the core 15 has a trapezoidal shape in section.
  • the dimensions of a cross section of the core can be variable over the length of the ski.
  • the structure, shape and dimensions of the core are not limiting for the invention.
  • the ski 1 has in its central area 10 a box structure.
  • the core 15 is surrounded on its four faces by reinforcement walls, an upper reinforcement wall 16, a lower reinforcement wall 17, and two lateral reinforcement walls 18 and 19.
  • the upper 16 and lower 17 reinforcing walls are of any suitable type, for example they are blades made of a light alloy, for example a high performance aluminum alloy.
  • the lateral reinforcement walls can be made of a composite structure constituted by fibers coated with thermosetting material such as an epoxy resin, or polyester, or also with thermoplastic material.
  • the upper and lower reinforcement walls can also be produced in such a composite structure.
  • the ski 1 has in its front region 11 and its rear region 12 a sandwich structure. In these zones, only the upper and lower faces of the core 15 are coated with upper and lower reinforcement walls. The lateral faces of the core 15 are not covered in these areas by any reinforcing wall.
  • the central zone 10 with its box structure gives the ski very good grip qualities, especially when cornering, and the front and rear zones, thanks to their greater flexibility, gives the ski an easy and tolerant ride. .
  • the reinforcement walls 16 and 17 described above extend continuously over the entire length of the ski, to form the upper and lower reinforcement walls of the zones with a box and sandwich structure.
  • the lateral reinforcement walls 18 and 19 are only present locally in the central zone 10.
  • Figures 6 and 7 show in developed a first embodiment of the reinforcing walls.
  • the upper reinforcement wall 16 has an approximately constant width, except in its median zone corresponding to the zone of the shoe 10, where it is extended laterally continuously by two lateral extensions 22 and 23. After range according to the lines shown diagrammatically by the dashed lines, these extensions 22 and 23 will form the lateral reinforcement walls 18 and 19.
  • the lateral extensions 22 and 23 Preferably, as can be seen in FIG. 8, the lateral extensions 22 and 23 have a trapezoidal shape, so that better distribute the connection constraints between the different zones.
  • lateral extensions could have any other suitable shape, for example a general parallelepiped shape.
  • FIG. 7 shows a top view of the lower reinforcement wall 17.
  • the width of this reinforcement wall is greater than that of the upper reinforcement wall 16, and moreover it is narrower in the central zone 10 only towards the ends, so as to give the ski a wasp size.
  • the lower reinforcement wall 17 is located between the edges 4 and 5, and in their lower parts, the side walls 18 and 19 are connected to the edges 4 and 5.
  • the ski further presents a lower layer 25 located under the wall 17, which constitutes the gliding sole. Above and on the sides, the ski has a decorative layer 26.
  • the layer 25 is of a known type, it is for example a layer made of polyethylene.
  • the decorative layer is of a known type, it is made for example from ABS, polyamide or polycarbonate. It can also have a relief.
  • FIG. 8 shows a variant construction of the central area 10 of the ski, that is to say the box structure area.
  • the ski has a double lower reinforcement wall, that is to say a wall 27 similar to the previous wall 17, and a wall 28 which covers both the wall 27 and the side edges 4 and 5
  • the side walls 18 and 19 are here connected to the side edges of the wall 28.
  • FIG. 9 shows another construction variant, according to which the lower wall 29 is lowered relative to the wall 17, and is engaged laterally under the flanges 31 and 32 that the edges 4 and 5 present towards the inside of the ski.
  • the side walls 18 and 19 are connected downwards to the edges 4 and 5.
  • FIGS 10 to 13 illustrate a variant construction of the ski previously described.
  • FIG. 10a shows the upper reinforcement wall 36 of the ski, in the form of a strip of substantially constant width over its entire length.
  • FIG. 10b shows another strip 37, the length of which corresponds overall to the length of the middle zone 10 of the ski.
  • This strip 37 comprises a central part 38 substantially the same width as the strip 36, and two lateral extensions 39 and 40, which, after folding around the lines shown diagrammatically by the dashed lines, constitute the lateral reinforcement walls of the ski in its zone to box structure.
  • FIG. 11 represents a cross section of the ski, in its box structure structure, according to a first relative arrangement of the strips 36 and 37.
  • the strip 37 has its central part 38 which is positioned above the strip 36, in the central zone 10 of the ski.
  • the strip 36 passes over the central part 36 of the strip 37.
  • part 38 reinforces the structure of the ski in its central zone where the binding elements will be assembled.
  • FIG. 10b represents lateral extensions 39 and 40 of trapezoidal shape, so as to have a good distribution of the forces at the level of the connections between the different zones.
  • This form is not limiting, and the FIG. 13 shows for this purpose a variant according to which the strip 37a has a central area 38a and extensions 39a and 40a in the general shape of a parallelogram.
  • the inclination of the side edges of the ski can be constant or variable throughout the length thereof.
  • the edges can be planar, substantially planar or else concave or convex over all or part of their length.
  • FIGS. 15 and 17 respectively represent cross sections of the Figure 14 ski at the DD, EE, FF lines.
  • Figures 15 and 16 show a similar structure, to within dimensions, with a core 55, an upper reinforcement wall 56, a lower reinforcement wall 57, and two lateral reinforcement walls 58 and 59.
  • Figure 17 shows the rear structure of the ski, with the core 55, and the upper and lower walls formed by the extensions of the walls 56 and 57. In this zone, the core is not coated with any lateral reinforcement wall.
  • Figures 15 to 17 also show an outer decor layer 66 which is of a type similar to the previous layer 26. This layer extends over the entire length of the ski.
  • the ski has excellent attachment qualities in the central zone 50 and the front zone 51.
  • the more flexible rear zone 52 gives the ski a tolerant ride.
  • This ski is well suited for so-called skidded turns.
  • the ski could have a box structure in its central zone and its rear zone, and a sandwich structure in its front zone.
  • central zones 10, 50 include the zone for mounting the fastening elements, in particular the standardized zone for mounting.
  • these areas 10, 50 are not limited to the borders of this mounting area, and may extend beyond forwards and backwards.
  • the ski according to the present invention can be manufactured by any suitable means.
  • the upper reinforcement wall could be inclined relative to the horizontal, over all or part of its length, and / or have a relief over all or part of its surface.
  • the invention applies not only to skis used for the practice of alpine skiing, but also to any board for sliding on snow or ice, in particular to boards used for the practice of snowboarding.
