Definitions

  • the present invention relates to a ski, in particular an alpine ski, a monoski or a snowboard.
  • 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 area of the ski, which has a relatively large thickness to give it great rigidity, causes a fairly significant distance of the bindings from the lower edges of the ski.
  • the lower edges are the elements which are intended to bite into the ice, when cornering.
  • the effectiveness of the lower edges provided with edges is all the better as the connection between the user's foot and the edge is more direct. The distance between the edge and the binding tends to degrade the effectiveness of the edges.
  • 465,794 describes a new ski structure having in particular on its upper surface, a middle rib extending longitudinally on either side of the central zone and the lowered lateral clearances bordering each side of this rib and on which rests a support or stirrup in the shape of an inverted "U" and intended to receive the fixings.
  • a second problem encountered in current ski structures is that in certain configurations, in particular when the skier is in front support, when entering a curve, or conversely, in rear support, when exiting. a curve ; the part opposite to the support is lightened and loses contact with the snow.
  • French patent applications Nos. 9,016,048, 9,105,012 and 9,204,190 propose replacing the middle rib by an added element, in one or two parts constituting a stiffener, partially linked to a base and which extends longitudinally, at least in the central region of the ski and advantageously beyond, that is to say over a length of between approximately 50 and 80% of the length of the base in contact with snow.
  • the stiffener makes it possible to obtain a balanced distribution of the pressures of the ski in dynamics and to avoid the aforementioned drawback of traditional skis whatever the configuration of the skier.
  • the ski gains in stability and depending on the stiffener setting and / or its design, the stability / maneuverability ratio can be improved.
  • the present invention is an improvement to this type of skis.
  • these new shapes and structures make it possible to increase the transmission of the efforts of the skier on the edges thanks to a more direct connection between the foot and the edge.
  • This transmission can have a drawback when the ski, driven on the edge at high speed, undergoes a point overpressure such as due to the meeting of an element of hard ice, for example. There can then occur a phenomenon of "stalling" which results in an involuntary lateral sliding of the ski on the side of the slope causing a deviation of trajectory.
  • the present invention proposes to resolve this drawback by reducing the maximum overpressure points which can be assimilated to a general vibratory phenomenon.
  • the behavior of the ski is improved by the fact that the extreme amplitudes are smoothed and the ski retains directional stability regardless of the surface condition of the terrain on which it operates.
  • the support can deform in the event of overpressure, by reducing the space of the recess and particularly its height.
  • the support plays the role of a suspension making it possible to avoid the phenomenon of "dropout".
  • the side wall of the support located on the inside of the ski is crossed by a front recess close to the front stop of the binding and a rear recess near the heel of fixing spaced from each other.
  • the front recess is requested mainly during the forward support of the skier exerted at the entry of the turn and the rear recess is mainly requested at the exit of the turn.
  • each side wall of the support is traversed by a front recess and a rear recess spaced from each other.
  • the length of each recess is between 15 and 150 millimeters and its height between 0.5 and 6 mm.
  • the recess is formed by a slot made in the side wall proper of the support, at a distance from the lower edge of the side wall of the support.
  • the ski has a lower sliding face (1) connecting to two lateral faces (2, 3) along two respective lower edges (20, 30) provided with metal edges.
  • the lateral faces (2, 3) are connected to an upper face (4).
  • the front end of the ski is bent upwards to form a spatula (5) between (A-A) and the front end of the ski.
  • the rear end of the ski is slightly curved upwards to form the heel (6) between (D-D) and the rear end of the ski.
  • (A-A) and (D-D) correspond respectively to the front contact line and to the rear contact line of the ski.
  • the ski may in particular comprise a tip tip (50), and a heel protector (60), fixed by any means such as snap-fastening, or gluing for example (as shown in FIG. 3 more specifically).
  • the upper face comprises a central rib (7) extending longitudinally in the central zone of the ski.
  • the central zone of the upper face of the ski constituted by the ski part located between 1/3 and 2/3 centered in the middle of the ski between the cutting zones BB and CC shown in FIGS. 1 and 2.
  • the middle rib (7) is raised relative to two lowered lateral parts (8, 9) bordering it on each side.
  • the middle rib (7) constitutes a thicker part of the ski, that is to say that the distance between the upper face of the middle rib (7) and the lower face (1) of the ski is increased, to give the central ski area with appropriate mechanical rigidity.
  • the length (L2) of the rib is preferably between 50 and 100% of the length (L1) of the lower sliding face (1) coming into contact with the snow, that is to say between ( AA) and (DD).
  • a support (10) of length (L) less than (L2) and having the shape of an inverted "U", intended to receive the fasteners (11) is supported on each lowered side part (8, 9). It is linked to these parts by any means such as gluing, screwing or welding. It comprises an upper wall (100) on which the fasteners (11) are screwed, and is extended laterally and downwards by two side walls (101, 102) to form a housing (12) intended for the passage of the middle rib (7).
  • the dimensions of the housing (12) both horizontal (l1) and vertical (h1) are greater than the respectively horizontal (l2) and vertical (h2) dimensions of the rib to form a space "e".
  • the side wall (102) of the support (10) located on the inside of the ski (INT) comprises at least one recess (13), preferably two recesses (130a, 130b) spaced apart from one other.
  • the front recess (130a) is located near and below the front stop (11a) of the binding (11) and the rear recess (130b) is located near and below the heel piece (11b) of the fixing.
  • Each recess extends horizontally so that its length (l) is greater than its height (h).
  • the length (l) of each recess is between 15 and 150 millimeters.
  • the length (l) is between 0.02 and 0.75 L when the side wall has only one recess. In general, the length (l) is between (0.02 / n) and (0.75 / n) L when the wall has n recesses.
  • each side wall (101, 102) can be crossed by one or more recess (130b, 131b) thus allowing the interchangeability of the right and left ski.
  • each side wall (101, 102) of the support can be provided with two recesses (130a, 130b, 131a, 131b) spaced from one another. It can also be provided that each recess has a different shape and / or length.
  • FIG. 4a represents the force F applied to the support vertically from the center of the recess as a function of the variation in the height of the recess (or clearance).
  • D1 corresponds to the straight line with a slope equal to 200N / mm and D2 corresponds to the straight line with a slope equal to 2000N / mm.
  • FIG. 5 shows two different ways of designing the recesses.
  • Each recess of the support (10) of FIG. 5 is formed by an open recess or depression produced on the lower edge (101a, 102a) of the side wall (101, 102) of depth equal to the height of the recess to be produced .
  • the recess thus constitutes a lumen when the support is in abutment on the lowered lateral parts of the ski.
  • each recess (130a, 130b, 131a, 131b) is constituted by a slot made in the side wall proper of the support and located at a certain distance from the lower edge (101a, 102a) of the side wall (101, 102).
  • the support is made of plastic or composite material accepting a certain deformation. It is produced in one piece, preferably by molding. Provision may be made for the upper support wall to include a metal or fiber-based insert (103), preferably glass, and resin, preferably phenolic, allowing the fastenings to be screwed, as shown in FIG. 6.
  • the insert can be embedded in the plastic during the molding of the support part.
  • Figures 7 and 8 show a variant in which the ski comprises a first lower assembly or base (40) and a second upper assembly or stiffener (70) intended to complete the distribution of stiffness of the base.
  • the stiffener constitutes the middle rib (7) in the central zone and is raised relative to the lateral parts (8, 9) of the base.
  • the stiffener is partially linked by each of its ends to the base by rigid or flexible connecting means (70a, 70b).
  • the flexible connection means can be constituted by an interface made of flexible elastomeric or plastic material, for example.
  • the structure of the base (40) can be of the sandwich type or of the box type or of any other type.
  • a preferred structure is shown comprising a rigid upper reinforcement (400), in the form of a shell with a "U" section forming a top wall (400a) and two side walls (400b, 400c) covering a core ( 401), the assembly being closed at its lower part by a lower element (402) comprising the metal edges (403), a sliding layer (404) generally made of polyethylene as well as lower reinforcement elements (405).
  • An upper protective and decorative layer (406) covers the upper reinforcement to form the decoration of the base.
  • the reinforcing layers (400, 405) can be of all types such as layers of composite materials such as fiberglass, carbon fiber with epoxy resin and / or polyester. They can also be made of metal, metal alloy or fibrometal.
  • the core (401) can be filled or unloaded foam, wood or aluminum honeycomb.
  • the monolayer or multilayer surface coating providing the decoration can be made of polyamide or other material, such as a thermoplastic material.
  • the structure of the stiffener may be of the box type with variable section along the ski, and formed of a core disposed between an upper reinforcement and a lower reinforcement (not shown). It can also be made up of a simple reinforced section with a longitudinally evolving section obtained by the TRE, SMC technique.
  • FIG. 10a represents two examples of curves (C1 and C2) for recesses having the general shape of FIGS. 9 and 10, that is to say at constant height.
  • the two curves C1 and C2 are linear but the slope of C1 is less than that of C2 because the length of the recess of C1 is less than the length of the recess of C2 (any other equivalent parameter elsewhere) .
  • FIGS. 11 to 12a show another example of the shape of the recess, the height of which is variable and which includes an upper edge (14) in steps.
  • the recess comprises a central part of the length (l4) and height (h4) situated between two lateral parts of length (l3) and height (h3); with (h4) greater than (h3).
  • FIG. 12a illustrates the curve (C) of variation of the arrow ⁇ h as a function of the applied force F at the center of the recess. This curve is divided into two straight line portions P1 and P2.
  • FIG. 13 illustrates a triangular-shaped recess, the upper edge (15) of which comprises a first increasing straight portion (150) connecting to a second decreasing straight portion (151).
  • FIG. 14 shows the progressive variation of the curve of the arrow as a function of the force applied to the point (152) of maximum height (h max).
  • FIG. 15 shows an advantageous variant of the invention which provides for the integration of the different parts constituting the ski between them.
  • the stiffener comprises a narrowing of its height (h5) extending at least over the corresponding length (L) of the support so as to form a clearance to reduce the height (h6) of the support and therefore the height of the fasteners compared to snow.
  • the height (h7) of the base varies to allow good integration of the support elements / base / stiffener between them.
  • FIG. 16 illustrates a variant in which the support consists of two independent half-supports (10a, 10b) spaced from one another, a first front half-support (10a) on which the front stop (11a) is fixed ) for retaining the shoe, and a second rear half support (10b) on which the heel piece (11b) is fixed.
  • the support consists of two independent half-supports (10a, 10b) spaced from one another, a first front half-support (10a) on which the front stop (11a) is fixed ) for retaining the shoe, and a second rear half support (10b) on which the heel piece (11b) is fixed.
