Definitions

  • the present invention relates to a snow board on snow such as a ski, a monoski, a surf, or other. It relates more particularly to an improvement relating to a gliding board comprising a base, on which is fixed at least one complementary element.
  • gliding boards and in particular skis, which are constituted by an elongated beam whose front end is raised to form the spatula, while the lower surface comprises a sliding sole bordered by metal edges.
  • the present invention provides multipurpose skis consisting of a base and at least one additional reinforcing technical element, including the cooperation of shapes, dimensions and structure, gives the entire ski its necessary characteristics, both comfort and skiing.
  • skis of the type mentioned in the previous paragraph are known to be disclosed by the French patent applications published under the numbers FR 2,854,333 , FR 2,834,906 .
  • the manufacture of such skis requires the assembly of complementary elements on the base, and given the geometry of the complementary elements assembly of the complementary elements generally made by hot welding, it is difficult to ensure uniformity of the assemblies and the reproducibility of ski performance.
  • the present invention proposes to overcome the disadvantages mentioned above.
  • the gliding board on snow such as a ski, a monoski or a surf, of vertical plane of general symmetry, comprising a main part, said body or base, constituted by a longitudinal rib formed by two lateral recesses which open laterally.
  • a lateral complementary element characterized in that the lateral complementary element is a reinforcing technical element which confers with their cooperation with the base the technical characteristics (rigidity, flexion, torsion etc.) necessary for the practice of the ski, and in that said complementary element extends laterally and longitudinally according to a thickness (e) substantially constant, at least in the assembly areas with the base.
  • the width of the complementary element is the same over its entire length.
  • the width of the complementary element is variable longitudinally, for example to be such that the width of the complementary element is wider at the center of the ski, and gradually decreases, towards the front and / or towards the rear.
  • the cross section of the complementary element has at least a portion of its length, or its entire length, the shape of a rectangle, or substantially the general shape of an S, or a curved shape convex towards the center of the base, or a curved shape convex towards the outside.
  • the shape of the profile in a cross section varies, for example such that, in the region of the base of the pad, the cross section has the shape substantially of S, while-in front and at the back the section of the profile is rectangular.
  • the ski with the general reference (1) is an elongated beam having a median vertical (P) plane of general symmetry whose front is raised to form the spatula (8).
  • the ski (1) is constituted by a main part which we will call body or base (2) on which at least one complementary element is fixed at least in the region of the shoe (4), and according to the preferred embodiment, two lateral complementary elements (3a, 3b).
  • the base (2) is the element in contact with the snow and has the shape of an elongate beam having on its lower surface a sliding sole (6) laterally bordered by lateral edges (7a, 7b) of metal.
  • the base (2) is an elongate beam whose front end is raised to form the spatula (8) of the ski.
  • This base (2) has its own distribution of thickness, coastline, width and stiffness and can be of all types and constitutions.
  • the elongate beam constituting the base (2) can be of all types of designs such as those known to date as, for example, sandwich type, box type, or shell type, or even the type combining shell and side fields, taken alone or in combination, or mixed and consisting of a set of elements and components known in themselves.
  • the upper surface of the base is advantageously made by a thermoplastic film, and to allow the assembly by gluing of complementary elements, as we will see later in the description.
  • the base (2) comprises lateral recesses (5a, 5b) in each of which is fixed one of the corresponding lateral complementary elements (3a, 3b).
  • the base (2) comprises a left lateral clearance (5a) in which is fixed the left lateral complementary element (3a), and a right lateral clearance (5b) in which is fixed the right lateral complementary element (3b).
  • each of the side clearances (5a, 5b) advantageously opens laterally outwards (EX) and upward (HA), while it does not open downwards (BA).
  • width (L1) of the clearances is advantageously longitudinally variable, to be wider in the center (40) of the ski (1), and advantageously decrease progressively, forward (AV) or rearward (AR), and advantageously forward (AV) and backward (AR). But it could of course be otherwise, that is to say that the width (L1) could be constant throughout its length.
  • the height (H1) of the fields (50a, 50b) of the base (2) is advantageously longitudinally variable, to be greater in the center of the ski, and advantageously decrease progressively towards the front (AV) or towards the rear (AR), and advantageously forward (AV) and rearward (AR). But it could of course be otherwise, that is to say that the height (H1) fields could be constant throughout its length.
  • the two lateral complementary elements (3a, 3b) consist of elongated profiles, which extend transversely and longitudinally, at least in the assembly areas with the base (2), according to a substantially constant thickness (e).
  • substantially constant is meant a thickness that does not vary by plus or minus 20%. This means that the thickness (e) of the cross section of the complementary element is substantially constant, and that likewise the thickness (e) of the longitudinal section of the complementary element is substantially constant and of course equal to the thickness of the cross section.
  • FIGS. 1, 2, 3, 4, 5A, 5B, 5C, 5D, 5E, 6A, 6B, 6C, 6D, 6E, illustrate a first embodiment according to which the complementary elements (3a, 3b) are profiles of which the cross section is rectangular in shape and the profile extends longitudinally along the same section, that is to say the shape of the cross section is identical over the entire length of the profile, to be of rectangular section over the entire length .
  • the width (L2) of the profile is variable.
  • the width (L2) of the lateral complementary elements (3a, 3b) advantageously decreases progressively from the central zone (40) towards the front (AV) and towards the rear (AR).
  • the complementary elements could be otherwise, for example such that the complementary elements are wider at the front than at the rear, with for example a gradual decrease in width from front to rear, or such that the complementary elements are wider at the rear than at the front, with for example a gradual decrease in width from the rear to the front.
  • the complementary elements could be such that their width is greater at the front and / or at the back while the part central would be of lesser thickness.
  • the width of the complementary elements could be constant instead of being variable.
  • the shape of the cross section is rectangular, but it could be otherwise. As for example according to the variants represented by FIGS. 7, 8, 9, 10.
  • the cross section of the complementary element has at least a part of its length, see its entire length substantially the general shape of an S with a lower lateral part (PI) connected to a part superior (PS) by a vertical or angled intermediate link (PIL).
  • PI lower lateral part
  • PS part superior
  • PIL vertical or angled intermediate link
  • the cross section of the complementary element has at least a part of its length, see its entire length a convex curved shape towards the center of the base.
  • the cross section of the complementary element has at least a portion of its length, see its entire length a curved shape convex to the outside.
  • the cross-section of the complementary element has, at least over a part of its length, to see its entire length a shape constituted by two rectangular parts (30, 31) connected by a projecting central part ( 32).
  • the thickness (e) of the profile is constant in the bonding areas (Z) on the base.
  • the shape of the profile in a cross section varies.
  • the cross section has the shape substantially of S, while at the front and rear section of the profile is rectangular.
  • the thickness (e) of the cross section of the complementary element is substantially constant, and that the thickness (e) of the longitudinal section of the complementary element is substantially constant and of course equal to thickness of the cross section.
  • each of the lateral complementary elements (3a, 3b) has its own configuration and structure. It has its own stiffness distribution and can be of all types of constructions.
  • said complementary elements (3a, 3b) may be formed by a one-piece element made of a single material. But it can be of an entirely different design as, for example, be of composite material, and in particular include on its lower surface a thermoplastic matrix film, to allow assembly.
  • the length (L3) of the lateral complementary elements (3a, 3b) may extend over all or part of the length of the base. It may be, for example, equal to or greater than 30% of the length (L4) of the base (2), such as, for example, between 30% and 90%. Thus, the length (L3) of the complementary elements may have, for example, a length of between 50 and 150 centimeters, for a ski having a length of 170 centimeters.
  • the two complementary lateral elements (3a, 3b) advantageously have the same length, but may have different lengths.
  • the base (2) comprises a longitudinal rib (11) bordered by the two lateral recesses (5a, 5b), the width (L5) of which is smaller than the width (L6) of the lower part (12) of said base (2).
  • Each of the lateral clearances is therefore limited towards the plane of symmetry (P) by the longitudinal rib (11) and downwards by the lower part (12) of the base which comprises the metal edges (7a 7b) and the sole of slip (6).
  • the ski (1) may be such that the left lateral complementary element (3a) is different from the right lateral complementary element (3b) by its length, as already mentioned above, but by its section, its transverse dimensions, its constructive characteristics, even its technical characteristics.
  • the assembly of one or more complementary elements is advantageously done by gluing and for example by hot gluing, by high frequency heating, or by thermal conduction.
  • the fact of having profiles of the same thickness over the entire width and over the entire length at least in the bonding areas, allows a homogeneous heat transfer and thus provides a consistent assembly and therefore reliable and reproducible.
  • the complementary elements (3a, 3b) can extend forwardly and / or rearward beyond the zone of the pad (4) and in this case the gluing of the latter can be carried out on their entire length, or partially, for example, being glued to the base only in the zone of the shoe (4), whereas the front and / or rear extension of these elements beyond the zone of the shoe would not be fixed to the base, to be for example just in support.
  • the complementary elements (3a, 3b) are reinforcing technical elements which confer with their cooperation with the base the technical characteristics (rigidity, flexion, torsion etc.) necessary for the practice of skiing.
  • the complementary elements (3a, 3b) for example made by thermocompression of fibrous reinforcing plies embedded in a thermoplastic or thermosetting matrix.
  • the reinforcing fibers are for example glass fiber type, high modulus carbon fiber or high tenacity.
  • the thickness (e) of the complementary element is for example between 1 and 15 millimeters.
  • the thickness (e) is for example between 5 and 10 millimeters, and set for example 6 millimeters.
  • Figures 12a, 12b, 12c and 13 are views of a ski in cross section according to four alternative embodiments.
  • the cross section of the complementary element has at least a portion of its length, see its entire length substantially the general shape of an S, whose lower part (PI) is substantially the same width as the upper part (PS).
  • the cross section of the complementary element has at least a portion of its length, see its entire length substantially the general shape of an S, the lower part (PI) to a width more weaker than that of the upper part (PS).
  • the cross section of the complementary element has at least a part of its length, see its entire length substantially the general shape of an S, whose lower part (PI) is larger than that of the upper part (PS).
  • the cross section of the complementary element has at least a part of its length, see its entire length substantially the general shape of an S, the upper part (PS) is curved for s 'extends downwards and the general plane of symmetry (P).
  • FIGS. 14A, 14B, 14C, 14D, 14E are views similar to the views of FIGS. 6A, 6B, 6C, 6D, 6E, but illustrating another variant embodiment in which the shape of the cross-section of the complementary elements varies longitudinally according to another variant.
  • the shape of the profile in a cross section is such that in the region of the pad (4) of the base, the cross section has a curved shape convex towards the outside, as in the illustration of FIG. 9, while at the front and back the profile section is rectangular.
