Definitions

  • the present invention relates to cross-country skiing, in particular for the practice of skating.
  • the interior and exterior terms are defined taking into account a pair of skis, the interior term being used for the part of the ski located directly opposite the other ski, while the exterior term is used to designate the part on the opposite side.
  • the oldest and most traditional technique is that of the alternative step, in which the two skis are moved alternately in two parallel tracks made in the track.
  • the second technique is that of the skater's step, more generally called skating.
  • the skier progresses by successively resting on the snow on each of his two skis, and making them diverge forward.
  • a shoe particularly suitable for skating is described in document FR A 2 697 141 in the name of the Applicant.
  • a cross-country ski has a front end called a tip, a rear end called a heel and a central part or skate area, the upper face of which is intended to receive a binding for a shoe.
  • the inner side of the ski consists of a side wall disposed during the period of use of a pair of skis, facing the corresponding side wall of the other ski, and an outer side constituted by the second side wall of the ski.
  • a cross-country ski comprises a lower assembly composed of a sole bordered with edges, possibly a reinforcing element, and an upper assembly composed of at least one filling core, an upper wall and side walls. , and possibly a reinforcing element.
  • the object of the invention is to provide a cross-country ski having an excellent efficiency by taking account of the successive phases of support on the snow during the practice of skating, without however requiring too expensive manufacturing of the entire ski. .
  • the ski which it concerns, of the aforementioned type comprises, in the central part or skid zone of the ski, a rigid reinforcement element having an upper wall, either located above the upper wall of the ski, either resting on the latter, or integrated in a zone in the recess of this wall, or finally integrated into the structure by locally replacing the upper wall, and two side walls pressed against the two lateral faces of the ski or integrated in these faces and taking support on the lower assembly of the ski, or themselves constituting the lower edges in the zones where they are located, the two side walls of the reinforcing element being offset longitudinally relative to one another, that located on the outside of the ski being offset towards the rear while that located on the inside of the ski is offset towards the front with respect to the upper wall of the element enhancement.
  • This reinforcing element improves efficiency by avoiding a twist of the ski in the central zone thereof, while making it possible to retain, for the rest of the ski, a traditional structure ensuring the desired flexibility to take account of the required performance and also comfort for the user.
  • the upper wall of the reinforcing element has a generally rectangular shape of width substantially equal to that of the ski and of length corresponding substantially to that of the boot, and in that the walls side of the reinforcing element each extend over at least part of the length of the upper wall and comprise, for the side wall located on the outer side of the ski, an extension towards the rear and for the side wall located inner side of the ski, a forward extension.
  • the upper wall of the reinforcing element is intended to be equipped, at its front end, with the shoe fixing stop, or a part of this stop.
  • the upper wall of the reinforcing element is in the form of a strip inclined relative to the longitudinal axis of the ski, extending from the outside of the ski, in the zone corresponding to the support of the heel of the boot, towards the inside of the ski, in the zone corresponding to the support of the front part of the boot.
  • the side walls of the reinforcing element extending from the edges of the upper wall, have extensions respectively towards the rear for the side wall located on the outside of the ski and towards the front for the side wall located on the inside of the ski.
  • the extensions of the side walls of the element reinforcement have heights which decrease from the central area of the ski towards the ends thereof.
  • the reinforcing element may consist, for example, of a plate of light metal alloy, such as an alloy known under the brand name Zicral, or be made of a composite material based on fibers and resin.
  • the reinforcing fibers are inclined relative to the longitudinal axis of the ski, that is to say mainly oriented at the level of the upper wall, from the rear towards the front and from the outside towards the inner side of the ski. This allows to benefit from maximum resistance in the oblique direction in which the forces are exerted during the different phases of the practice of skating.
  • the upper wall of the reinforcing element can be placed above the upper face of the ski, in contact with this face or at a distance therefrom, or embedded in a recessed area that comprises the upper surface of the ski, or integrated into the structure of the ski, locally replacing the upper wall thereof.
  • the side walls of the reinforcement element can be arranged outside the side faces of the ski or integrated into the structure of the ski, by locally replacing the side faces of the latter.
  • the side walls of the reinforcement element can be linked to the side faces of the ski, and the upper wall of the reinforcement element can be linked to the upper face of the ski, these connections being obtainable by known means such as bonding , screwing, riveting or welding, the bonding being for example carried out by means of a visco-elastic film.
  • FIG. 1 represents a cross-country ski 2 for the left leg, comprising a central part or skid zone 3, a raised front end 4, called the tip, and a thinned and slightly raised rear end 5, called the heel.
  • This ski comprises, as shown in particular in FIG. 4, a lower assembly composed of a sole 6 bordered with edges 7, and possibly comprising a reinforcing element not shown, and an upper assembly composed of at least one filling core. 8, a reinforcement element not shown, an upper wall 9 and side walls 10a and 10b, the side wall 10a corresponding to the inner side, that is to say to the wall located directly opposite the corresponding wall of the other ski of the same pair, while the side wall 10b corresponds to the outside.
  • the ski 2 is equipped, in its central part, with a rigid reinforcement element 12, comprising an upper wall 13, and two side walls 14a and 14b pressed against the two side walls 10a and 10b.
  • the connection between the reinforcing element and the ski is produced by a film 11 of visco-elastic material.
  • the lower edges of the two side walls 14a and 14b bear on the upper face of the lower edges 7 of the ski.
  • the edges of the ski could be interrupted at this level and the edges lower side faces could then themselves constitute the lower edges of the ski in the areas where they are located.
  • the upper wall 13 of the reinforcing element 12 can bear on the upper wall 9 of the ski according to FIG. 4, or be integrated into this wall, as shown in FIG. 5.
  • the upper face 9 of the ski has a recess 9a on the side of the core 8, allowing the upper wall 13 of the reinforcement element 12 to be embedded.
  • the upper wall 13 of the reinforcement element is located above above the upper face 9 of the ski, without resting on the latter.
  • FIGS 7 and 8 show another embodiment of a ski, in which the same elements are designated by the same references as above.
  • the upper wall 13 and the side walls 14a, 14b of the reinforcing element are integrated into the structure of the ski, in contact with the core 8 or reinforcements covering it, and locally replace the upper face 9 and the side faces 10a, 10b of the ski.
  • the upper wall 13 of the reinforcing element has a generally rectangular shape, of width substantially equal to that of the ski and of length corresponding substantially to that of the boot.
  • the upper wall 13 of the reinforcing element is in this case, as shown in FIG. 3, equipped with the binding 15 of the skier's boot.
  • the side walls 14a and 14b which extend the upper wall 13, respectively have an extension 16a towards the front, for the side wall 14a located on the inside, and an extension 16b towards the rear, for the side wall 14b located at the outside of the ski.
  • the respective heights of the two extensions 16a and 16b decrease in the direction of the corresponding ends of the ski, that is to say in the direction of the tip 4 for the extension 16a and of the heel 5 for the extension 16b.
  • Figures 9 and 10 show an alternative embodiment of this ski in which the upper wall 23 of the reinforcing element is in the form of a strip inclined at an angle a relative to the longitudinal axis of the ski extending from the outside of the ski, in the zone corresponding to the support of the heel of the boot, towards the side inside the ski, in the zone corresponding to the support of the front part of the boot. From the inclined strip 23, forming the upper wall, extend two side walls 24a and 24b, provided with extensions 26a and 26b.
  • the reinforcing element must be rigid and preferably light, and for this purpose is produced, for example, in a plate of light metal alloy, such as Zicral, or in a composite material based on reinforcing fibers and resin.
  • the reinforcing fibers 27 can be inclined relative to the longitudinal axis of the ski, that is to say mainly oriented in the same direction as the strip 23, from the rear forward and from the outside to the inside of the ski.
  • the invention brings a great improvement to the existing technique by providing a cross-country ski of simple design, the structure of which is perfectly suited to the practice of the skating technique.
