Definitions

  • the invention relates to the field of piste skiing, more precisely it relates to a ski which has a device for shifting the position of the skier's foot with respect to the median longitudinal axis of the ski as a function of the intensity of the impulses generated by the skier, when taking the edges.
  • the dimension line of a ski is according to a standard definition, the line that represents the lateral contour of the surface of ski slides in the area between the point of maximum front width and the rear maximum width point. This line is defined by the lower edges.
  • the dimension line of a ski intended for special slalom is generally more dug that the side line of a ski for the giant slalom.
  • a hollowed out dimension line brings the bottom edge closer to the axis longitudinal median of the ski, which reduces the torque as well as the time required for passing from one edge to another and therefore increases the speed of execution.
  • this device consists of a platform capable to move transversely on the upper face of the ski, and connected to this the latter by means of compression springs. So during the phases of propulsion when the skier exerts a lateral and transverse force, parallel to the upper side of the ski, the platform moves by compressing the springs cited above. The apparent hardness of the ski is therefore modified, which improves comfort of the skier. In no case can this solution be transposed to the ski area of track. Indeed, such a device mounted on an alpine ski would cause a flutter of the foot relative to the board, which would result in risks of crossing skis and fall.
  • the problem that the invention seeks to solve is to allow adaptation dynamics of the transverse position of the binding as a function of the intensity of the impulses applied by the skier on the ski.
  • This ski is characterized in that said offset means act under the effect of a force directed perpendicular to the upper face of the gliding board, causing a lateral offset from the median longitudinal plane of the platform, said lateral offset being a function increasing of said force.
  • the attachment installed on the characteristic platform has a displacement capacity relative skiing.
  • the intermediate device is arranged in such a way that when the skier exerts a vertical impulse, the latter causes a modification of the position of the platform relative to the upper face of the ski.
  • This displacement is an increasing function of the intensity of the impulse exerted by the skier, that is to say that the offset is all the greater as the force applied by the skier is great.
  • the thrust it produces when the skier enters a turn, causes the offset of its shoe towards the inside of the ski.
  • the internal edge is thus found in a position closer to the bottom of the shoe, which promotes behavior ski dynamics.
  • this impulse characteristic may cause the platform to pivot relative to the face superior of the ski, resulting in the fact that the ski turns by an angle more important that the shoe to obtain an oversteering effect allowing accentuate the completion of the turn.
  • the intermediate device comprises means for adjusting the threshold for implementing the shifting means.
  • the intermediate device only produces its effects from of a pulse intensity, therefore of an adjustable force depending in particular on the weight of the skier.
  • the means capable of modifying the position of the median plane of the platform in cause the transverse translation towards the internal edge, under the effect a crushing force directed towards the upper face of the ski.
  • the turn initiation pulse causes the shift of the foot inward, in a direction of movement substantially perpendicular to the longitudinal plane of the ski.
  • the axis of the shoe remains parallel to the axis of the ski.
  • the internal edge is slightly offset under the shoe, which which allows, as desired, to reduce the tilting time from one edge to the other.
  • the means intended to cause the transverse translation of the platform are constituted by at least one ramp inclined downwards towards of the internal edge, in contact with at least one stop, also inclined each located respectively on the platform and on the upper face of the ski.
  • cam surfaces arranged opposite between the platform and skiing channel the impulse and convert part of it into displacement transverse.
  • the stop can be constituted by a ramp inclined, or a cylindrical roller whose axis of revolution is parallel to the axis longitudinal of the ski.
  • the means intended to allow the transverse translation of the longitudinal plane of the platform consist of at least two arms of link articulated at their upper and lower ends respectively under the platform and on one side of the ski, around axes parallel to the longitudinal axis ski.
  • the platform is connected for example to the upper face of the ski by a number of arms which allow, during a vertical impulse, the pivoting of the longitudinal axis of the platform with respect to the longitudinal axis skiing, by a deformable parallelogram effect.
  • the return members are constituted by studs in elastic material, or by elastic spring blades, of metal or other, or even again by helical coil springs.
  • the means intended to allow the transverse translation of the plane longitudinal of the platform consist of at least one elastic blade disposed between the platform and the upper surface of the ski, said blade being oriented towards the underside of the ski and towards the outer edge.
  • the platform is connected to the surface upper of the ski by at least one blade oriented in such a way that the depression of the platform results in a deformation of the elastic blade causing the transverse offset of the platform.
  • the elastic blade also ensures the recall of the platform in its rest position when the pulse is finished.
  • the elastic blade can be embedded in an elastomeric stud which increases the recall capacity of the intermediate device.
  • the vertical impulse given to the platform causes crushing and shearing of the elastic wedge.
  • the difference in thickness of the corner elastic due to the shape of the sloping wedge causes this shearing and therefore, the transverse shift.
  • the invention uses the bending of the skiing following a push exerted by the skier, to modify the position of the internal edge.
  • the board forming the ski bends downwards. So the fictitious line connecting two fixed points located above the ski will become a rope all the more short as the radius of curvature of the ski will be small.
  • the invention therefore consists in use this bringing together of these fixed points and channel it using means advantageously distributed on the upper face of the ski and under the platform.
  • the means intended to allow the transverse translation of the plane longitudinal of the platform consist of at least two grooves of guide cooperating with two pins each arranged on the underside of the platform and on the upper face of the ski, the directions of the grooves converging on the side of the outer edge of the ski.
  • the intermediate device also comprises at least one additional groove, in direction parallel to the bisector of the directions of guide grooves.
  • this complementary groove whose direction is identical to that of the movement of the platform, ensures positive guidance of the offset transverse.
  • the grooves are arranged on the platform and form through lights.
  • the angle of inclination of these guide grooves relative to the longitudinal plane of the platform is included between 30 ° and 60 °, and more favorably at 45 °.
  • the means intended to allow the transverse translation of the plane longitudinal of the platform consist of a set of at least two journals integral with the upper face of the ski, said journals receiving cylindrical cams able to pivot eccentrically around the journals, said cams cams cooperating with complementary cylindrical housings formed in the platform, so that the approximation of the pins causes the rotation cylindrical cams inside the housings, and therefore the lateral displacement of the platform.
  • the intermediate device comprises two platforms respectively supporting the toe piece and heel piece of the safety binding, so as to cause rotation from the longitudinal axis of the skier's foot, around an axis perpendicular to the face superior of skiing.
  • the means characteristic of the invention are reversed from one platform to another, while in another family, these means cause displacement in the same direction but cause an offset of different amplitude from one platform to another.
  • the invention conforms to this third principle of operation causes the fixation to pivot by a different offset from identical or opposite direction of the stop and the heel.
  • the direction of the longitudinal axis of the foot is distinguished from that of the longitudinal axis of the ski to obtain an oversteer effect allowing to accentuate the closure of the turn.
  • the intermediate device of this embodiment corresponds to two platforms already mentioned, combining cam surfaces in gaze, placed inversely to each other.
  • the inclination of the first and second inclined ramps are different, which ensures the pivoting of the longitudinal axis of the shoe compared to that of the ski.
