Definitions

  • the present invention relates to an improved ski, such as an alpine ski, a cross-country ski, a monoski or a snowboard.
  • skis consist of an elongated beam whose front end is curved upwards to form a spatula, the rear end also being more slightly to form the heel.
  • Current skis generally have a composite structure in which different materials are combined so that each of them intervenes optimally, taking into account the distribution of mechanical stresses when using the ski.
  • the structure generally comprises peripheral protection elements, internal resistance elements to resist the flexural and torsional stresses, and a core. These elements are assembled by gluing or by injection, the assembly generally being carried out hot in a mold having the final shape of the ski, with a front part strongly raised in a tip, a rear part slightly raised in the heel, a central arched part. .
  • Application FR-A-2 675 392 of the applicant relates more particularly to a damping device for skiing consisting of at least one flexible blade connected to the ski by a rigid connection means and at least one flexible connection means; said means being spaced longitudinally from each other on said blade.
  • Application FR-A-2 678 517 by the applicant relates to another damping device in which the flexible connection means is replaced by a friction means.
  • the friction means is of the viscous type.
  • the present invention is not limited to a vibration damping device as the prior art teaches. Indeed, for certain types of ski, certain stresses at the front and / or at the rear do not necessarily require dissipation but on the contrary a return force without cushioning to provide more maneuverability. On the contrary, for other skis, it will be necessary to provide a response in terms of damping to increase stability and precision at high speed.
  • the present invention therefore proposes to provide an improvement to the skis of the prior art while taking more account of the needs of the skier.
  • the invention relates to a ski consisting of an elongated beam having a central arched length LC length between a front contact line and a rear contact line; a front part raised in tip and a rear part less raised in heel; said central part comprising an area for mounting the fasteners corresponding to the standardized area.
  • the ski comprises two transmitters arranged in said central part and each on either side of said area for mounting the bindings; one end of each transmitter being connected to the beam by a fixed link; the other end of each transmitter being connected to the beam by a partial connection means, free in translation in a longitudinal direction, composed of an elastic and / or viscous element which opposes the longitudinal movement of said transmitter; under bending stress applied to the middle of the LC, the displacement ( ⁇ 1) of the partially linked end of the front transmitter being greater than the displacement ( ⁇ 2) of the partially linked end of the rear transmitter; so that the ratio ⁇ 1 / ⁇ 2 is between 1.2 and 2.5; and the stiffness (K1) of the elastic and / or viscous element of the front transmitter being greater than the stiffness (K2) of the elastic and / or viscous element of the rear transmitter; so that the ratio K1 / K2 is between 1.2 and 5.
  • the ratio ⁇ 1 / ⁇ 2 is characteristic of the balance necessary for satisfactory behavior of the ski with regard to the values of amplitudes of the stresses transmitted by the transmitter and "treated" by the end comprising the elastic or visco-elastic means.
  • the deformations at the front of the ski are, in general, greater than those at the rear, it is therefore necessary to provide a ratio ⁇ 1 / ⁇ 2 in the range mentioned above.
  • the K1 / K2 ratio is characteristic of the balance and efficiency of the energy transmitted by the transmitters. In other words, comparatively, it is planned to dissipate or restore more at the front of the ski due to the fact that the energy transmitted by the front transmitter is greater than that transmitted by the rear transmitter.
  • each transmitter has a free length (lT1, lT2) between each fixed link and each partial connection means; the ratio of the free length (lT1) of the front transmitter to the free length (lT2) of the rear transmitter being between 1.5 and 2.5 and the ratio (lT1 + lT2) on LC being, meanwhile, between 0 , 15 and 0.25.
  • the ski is equipped with transmitters, in the chosen length ratios, on either side of the mounting area, it is possible to obtain a control of the dynamic deformation of the front part and of the rear part of the ski. ski, and thus a perfect balance and stability of the whole.
  • each transmitter must cover an "active" area of the ski, that is to say that between the contact line (front or rear) and the mounting area which corresponds to the free part in contact with the snow. .
  • each transmitter The role of each transmitter is to oppose the stresses which have the effect of taking off each "active" part of the snow surface by damping effect or by elastic return effect as the case may be.
  • the overlap length of the transmitters must be sufficient but suitable for each use.
  • the report (lT1 + lT2) / LC must be within the limits defined above.
  • each transmitter is connected by a complete link and is located on the side in the direction of the front or rear part, the other end being located on the side in the direction of the mounting area. . Therefore, the stresses of large amplitude at the ends are picked up by the fixed end of the stiffener, transmitted by the free part then "treated" at the end of the transmitter provided with the partial connection means of the elastic and / or viscoelastic type. in a region close to that where the weight of the skier is distributed, therefore more stable.
  • the distance (d1) separating the front end of the front transmitter from the front contact line is between 0.18 LC and 0.25 LC.
  • the distance (d2) separating the rear end of the rear transmitter from the rear contact line is between 0.16 LC and 0.21 LC.
  • the partial connecting means can be constituted by different means depending on the desired effect.
  • the partial connection means consists of an interface layer of elastic or viscoelastic material connecting, at least, the underside of the end of each transmitter above the beam in order to work in shearing by the longitudinal displacement of said end relative to the beam.
  • the choice of such a solution has the advantage of limiting the size of the device, in particular the height of the latter relative to the beam of the ski. It is, on the other hand, particularly simple in its implementation, economical, and reliable in operation.
  • the viscoelastic properties of the material providing the interface make it possible to dissipate the energy transmitted by the device.
  • the partial connection means may also consist of a spring / stop assembly working on compression. This system, unlike the previous one, does not dissipate the energy transmitted but provides an elastic response which tends to oppose the deformation of the front or rear part of the ski.
  • the spring can be replaced by an elastic or viscoelastic buffer.
  • the spring or elastic or viscoelastic buffer assembly can also be provided for working in traction.
  • the ski according to the invention comprises an elongated beam (1) having its own distribution of thickness, of width and therefore its own stiffness.
  • the beam can be divided into several separate parts; a central arched part (2) of length LC, delimited by a front contact line (20) and a rear contact line (21).
  • a central arched part (2) of length LC delimited by a front contact line (20) and a rear contact line (21).
  • the ski rests according to the two contact lines (20, 21).
  • the contact between the lower surface of the ski and the snow is made between the contact lines (20, 21) on a surface of length LC, due to the cancellation of the camber of the ski.
  • the beam also includes a front tip portion (3) beyond the front contact line (20). This part is strongly raised, as known per se. Below the rear contact line (21) extends a rear part of the heel (4) which is less raised.
  • the central part (2) includes an area for mounting the fasteners (5) corresponding to the so-called "standardized" area.
  • the standardized area is defined by standard IS0 8364.
  • the standard is DIN-IS0 9119.
  • the standard is being development (IS0 10958).
  • the beam (1) of the ski is overcome in its central part (2) and on either side of the mounting area (5) by two transmitters (6, 7).
  • the term “transmitter” is used to designate any elongated element which is relatively flexible so as not to provide excess stiffness locally, but which is sufficiently resistant to buckling in order to be able to fulfill its function of transmitting stresses from one end to the other.
  • the buckling resistance function can be partially fulfilled by additional guiding means in the free part of the transmitter, of the slide, stirrup type, etc.
  • the transmitter can consist of a blade, a profit or even a rod.
  • a profile (with an evolving section), the central part of which comprises a section in the form of an inverted U to increase its resistance to buckling and the ends of which are flat to facilitate its attachment to the ski.
  • the constituent material of the transmitter can be chosen from plastics, composite materials and metals, for example.
  • Each transmitter is arranged in the direction of the longitudinal axis of the ski.
  • the end (60, 70) of each transmitter located on the side towards the contact lines (20, 21) is rigidly fixed to the beam by a fixed link (8).
  • fixed connection means a connection that does not allow any degree of freedom of the end (60, 70) relative to the beam. It can be a connection by screws, by gluing or even by welding. When the materials forming the top of the beam and those forming the transmitters are compatible with each other, it is preferable to bond the transmitter to the beam by the vibration welding process.
  • each transmitter is connected to the beam by a partial connection, free in translation in the longitudinal direction (I, I ') of the ski.
  • partial link is meant a link which allows a degree of freedom. In the case of the present invention, the choice of the direction of this degree of freedom is that of the direction along the axis (I, I ').
  • Each partial connection means consists of an interface layer (90, 91) of elastic or viscoelastic material connecting, at least, the underside of the end (61, 71) of each transmitter above the beam. ski.
  • the hardness of an elastic material used can vary from 10 to 85 shore A.
  • the hardness varies from 50 to 95 shore A for a modulus of elasticity between 15 and 160 MPa and a damping value of 0 , 13-0.72.

  • the length (lT1) of the free part of the front transmitter (6) is greater than the length (lT2) of the free part of the rear transmitter; the ratio (lT1 / lT2) being more precisely between 1.5 and 2.5.

  • the report (lT1 + lT2) / LC is characteristic of the front / rear efficiency of the device.
  • the fixed end (60, 70) of each transmitter must be located near its respective contact line (20, 21); at a certain distance (d1, d2) from it, however.
  • the distance d1 separating the front end (60) of the front transmitter (6) from the front contact line (20) must be between 0.18 LC and 0.25 LC.
  • the distance d2 separating the rear end (70) from the rear contact line (21) must be between 0.16 LC and 0.21 LC. Failure to respect these ranges results in unsatisfactory behavior of the ski which results in a tendency to understeer (in the sense that it is necessary to exert a greater effort to shorten the radius of curvature when cornering), when d1 and d2 are lower than the characterized ranges, and a tendency to lose stability and precision of the ends (tip / heel), when d1 and d2 are greater than the characterized ranges; any other parameter of the ski being identical elsewhere.
