Definitions

  • the invention relates to a ski binding for the practice of Nordic skiing in which the skier raises the heel alternately, such as telemark, ski touring, ski-wheels or cross-country skiing.
  • the invention also relates to a ski comprising such a binding.
  • Ski bindings for Nordic skiing generally comprise a plate provided with a retaining device for removably fixing the ski boot of a user.
  • the shoe assembles with the ski at its front end with the possibility of rotation around a crossbar, generally a pivot, integral with the shoe.
  • a crossbar generally a pivot
  • the transverse pivot of the shoe is held between a fixed jaw and a movable jaw of the retainer.
  • the movable jaw is mounted on a carriage mounted longitudinally movable along the axis of the ski, and can be manipulated using a lever.
  • the retainer further defines a housing for an elastic buffer having a bearing surface cooperating with a vertical face of the end of the ski boot.
  • the elastic pad is intended to exert a return force on the shoe when the heel of the latter is raised from the upper surface of the ski.
  • the ski boots To cooperate with the elastic pad, the ski boots have reinforcements at their front ends, these to prevent excessive deformation of the tip of the ski boot.
  • the rod is then less flexible at the foot of other levels, which can cause discomfort to the user after prolonged use.
  • the tip of the user's foot does not always allow the user to have a stable support to obtain a satisfactory control of the ski guide and an appropriate transmission of sensory sensations at the foot of the foot. 'user.
  • the present invention therefore aims to provide an improved attachment, including a better guide of the ski by optimizing the transmission of driving impulses or sensory information between the skier and the ski.
  • the subject of the invention is a ski binding comprising an elastic buffer intended to exert a return force on a boot when the heel of the latter is raised from the upper surface of the ski, characterized in that said pad spring has a bearing surface intended to abut with the underside of the sole of the ski boot and whose angle between said bearing surface and a plane substantially parallel to the upper surface of the ski, is between 0 and 80 °.
  • the angle is measured while the elastic pad is not subjected to deformation in compression on its bearing surface.
  • the angle between said bearing surface and a plane substantially parallel to the upper surface of the ski is between 0 and 40 °.
  • the bearing surface no longer abuts the user's foot but is shifted under its foot, which increases the force available to the user since that it exerts an essentially vertical force, also giving it a better stability of the supports and a greater precision of movement.
  • the leverage around the transverse pivot of the shoe is accentuated so that the torsion of the shoe is reduced at the level of the upper and the sole, which allows a better control of the ski guidance.
  • the feeling of comfort is progressive throughout the shoe, the user no longer observes a break in the flexibility of the sole of the shoe. He then has a better sensory transmission between his foot and the ski.
  • the attachment comprises a retaining device comprising a fixed jaw and a movable jaw between a spaced apart position and a close position of said fixed jaw, the distance between the fixed jaw and a rear edge of the bearing surface.
  • elastic buffer being less than 10 millimeters in the close position.
  • the elastic buffer is integral with the movable jaw.
  • the invention also relates to a ski comprising a binding as described above.
  • FIGS. 1 to 6 represent a ski and a shoe for Nordic skiing in which the skier raises the heel alternately, such as telemark, ski touring, ski-wheels or cross-country skiing.
  • the different types of skis for the practice of Nordic skiing disciplines will be referred to as the general term cross-country ski or even simply ski.
  • the ski 1 comprises a gliding board 2 on which a fixing 3 is mounted.
  • the binding 3 comprises a plate 4 intended to be fixed to the gliding board 2 and a retaining device 5 for removably retaining a ski boot 6.
  • the retaining device 5 comprises a fixed jaw 7 and a movable jaw 8.
  • the movable jaw 8 can move between a spaced apart position (not shown) and a close position ( figures 1 and 3 to 6 ) for this, the movable jaw 8 is mounted longitudinally movable along the longitudinal axis L of the ski 1 on a carriage 9 of the retaining device 5.
  • the carriage 9 can be operated manually with the aid of FIG. a lever 10 of the retainer 5. It can also be provided that the carriage can be moved automatically (not shown).
  • the carriage 9 is provided at the front of the attachment 3 on the gliding board 2. Note that the movable jaw is located more towards the front of the attachment 3 than is the fixed jaw. However the opposite is possible.
  • the shoe 6 has a sole 11 on which is secured a rod 12 having an opening 13 for the introduction of a foot of a user.
  • the sole 11 and the rod 12 extend longitudinally along the longitudinal axis L 'from the heel 14 at a rear end to the tip 15 at a front end, the longitudinal axis L' of the sole 11 and the longitudinal axis L of the ski 1 being substantially parallel.
  • the shoe 6 further has a first transverse bar or first pivot 16, substantially perpendicular to the longitudinal axis L 'of the shoe 6 and integral with the sole 11, disposed at the front of the sole 11. The ends of the transverse pivot 16 are embedded in the sole 11.
  • the transverse pivot 16 of the shoe 6 is configured to fit between the fixed jaw 7 and the movable jaw 8 of the attachment 3 in the spaced apart position and be held by them in a close position, thus preventing the transverse pivot 16 from coming out of its housing, then fixing the front of the shoe 6 to the ski 1.
  • the pivot or bar 16 has a circular section, but other sectional shapes may be suitable.
  • the transverse pivot 16 is placed under the sole 11 of the boot 1, for example at a distance d1 between 13 and 20 millimeters to the right of the front end of the sole 11 ( figure 2 ). More specifically, the distance d1 is the distance between the axis of the transverse pivot 16 and an imaginary projection of the front end of the sole 11 in a plane parallel to the surface of the ski containing the axis of the transverse pivot 16.
  • the retaining device 5 of the attachment 3 also delimits a housing (not visible) for an elastic buffer 17.
  • the housing is for example arranged in the carriage 9, between the arms of the fixing lever 3.
  • the elastic pad 17 has a bearing surface 18a on its upper wall, intended to abut with an abutment surface 18b located in a clearance 25 below the sole 11 of the ski boot 6. As shown in FIGS. Figures 1 to 4 the abutment surface 18b may have a convexly convex shape.
  • the elastic buffer 17 is intended to exert a return force on the shoe 6 when the heel 14 thereof is raised from the upper surface S of the ski 1. Thus, once the ski and the shoe assembled, the shoe 6 can pivot about the transverse pivot 16 against the elastic buffer 17.
  • the angle ⁇ between the bearing surface 18a and a plane substantially parallel to the upper surface S of the ski 1 is between 0 and 80 °.
  • the angle ⁇ is measured while the elastic pad 17 is not subjected to compressive deformation on its bearing surface 18a.
  • the angle ⁇ is between 0 and 40 °.
  • the feeling of comfort is progressive throughout the shoe, the user no longer observes a break in the flexibility of the sole 11 of the shoe. He then has a better sensory transmission between his foot and the ski. He no longer has the feeling of stop of his toes against the pad, hence a better comfort.
  • the distance d2 between the fixed jaw 7 and the rear edge of the bearing surface 18a is less than 10 millimeters when the movable jaw 8 is in the close position ( figure 3 ), for example the distance d2 is of the order of 5 millimeters.
  • the bearing surface 18a of the elastic pad 17 is further away from the plate 4 or the ski 1 than the pivot 16.
  • the tilting of the shoe 6, when the heel 14 is raised in s' away from the plate 4 causes a vertical compression of the elastic pad 17 by the tip 15. More precisely it is the part of the sole 11 located at the tip 15, in front of the pivot 16, which compresses the pad 17. Then the bearing surface 18a descends towards the plate 4. It may happen that a large tilting of the boot causes a lowering of all or part of the bearing surface 18a below the level of the pivot 16.
  • the same attachment 3 is suitable for different types of shoe insoles having a crossbar 16 and regardless of the shape of said sole or the position of the crossbar 16 under said sole.
  • the elastic pad 17 comprises two parts, namely a recess portion (not visible) and a part designed more specifically for the deformation.
  • the embedding portion of the buffer is embedded in the housing provided for this purpose in the fastener retaining device 3, while the deformation portion of the pad 17 is intended to cooperate more particularly with the shoe 6 by the surface associated support 18a during the rotation of the boot 6 relative to the ski 1.
  • the housing formed in the retaining device for the elastic buffer 17 has, in transverse direction, dimensions greater than those of this elastic buffer 17 allowing expansion in the transverse direction of the buffer 17 during its compression by the boot 6, without however hinder its penetration inside the housing.
  • the elastic pad 17 has a generally accordion-like shape, comprising a series of parallel notches 19 on the side walls of the pad 17.
  • This series of notches 19 delimits layers whose size has been reduced since embedding portion to the bearing surface 18a.
  • the deformation portion has a pyramidal shape, with a base located at the intersection of the embedding and deformation parts.
  • the elastic pad 17 also has internally a series of ribs (not visible in the figures) extending parallel to each other. Each inner rib extends in the extension of a notch 19. The inner ribs are intended to exert a certain retaining force of the side walls of the elastic pad 17.
  • the outer cuts 19 are intended to allow a better compression of the elastic buffer 17 by stacking the different successive layers determined between each of these cuts 19 (see more particularly the figure 4 ).
  • the elastic pad 17 has, in its deformation portion, a substantially pyramidal shape tapering towards the bearing surface 18a, which allows a stack of layers.
  • the elastic pad 17 has, in the extension of its bearing surface 18a, at the rear edge, a catch tab 26 extending downwards and intended to anchor in an associated part of the attachment. 3.
  • This attachment tongue is intended to be fixed in the housing by means of a pin 20 shown on the figure 3 .
  • the tongue prevents, by its anchoring in the binding 3, any upward detachment of the elastic pad 17 during the lifting of the shoe 6, and therefore during the compression of this elastic pad 17.
  • it can be provided by other means of securing the buffer, such as embedding, gluing, or other.
  • an elastic buffer 17 made of elastomer, such as a thermoplastic material is provided.
  • elastomer such as a thermoplastic material
  • SEBS Styrene-Ethylene-Butadiene-Styrene
  • the plate 4 may also have a longitudinal guide edge 21 to the longitudinal axis L of the ski.
  • the guide edge 21 is intended to cooperate with a groove 22 of complementary shape provided under the sole 11 of the shoe 6 for lateral support of the shoe assembled to the binding 3 in a first position in which the heel 14 of the shoe is in support on the ski.
  • the guide edge 21 has for example a parallelepipedal overall shape having a length of between 28 and 35 cm and a width of about 2 cm. It can be extended at the front by the fixed jaw 7.
  • the guide edge 21 may be continuous or segmented by at least one transverse slot 23a, 23b. For example, it is provided that the guide edge 21 is segmented to allow the ski 1 to maintain good flexibility.
  • the guide edge 21 extends along the entire length of the sole of the shoe.
  • the sole 11 of the shoe has for example a longitudinal guide groove 22 of complementary shape extending from the tip 15 of the shoe to the heel 14.
  • the abutment surface 18b can be arranged in the extension to the front of the shoe. the guide groove 22. It may be provided that the upper edge of the edge 21 contacts the bottom of the groove.
  • the guide groove 22 then has a complementary parallelepipedal general shape with for example a width of 3 cm.
  • a complementary parallelepipedal general shape with for example a width of 3 cm.
  • other embodiments can be envisaged for the groove and the guide edge, such as trapezoidal profiled shapes or thinned towards the rear end. It is also possible to provide several guide edges.
  • the sole 11 of the ski boot 6 has an additional transverse bar or pivot.
  • the fixing plate comprises a hook fixed to the plate by an elastic return means to help the skier to bring the heel towards the ski, when the heel has been raised with respect to the ski.
  • the ski takes over more easily a position parallel to the sole of the shoe.
  • the figures 5 and 6 illustrate a second variant of the second embodiment of the attachment.
  • the shoe and the ski have the same elements bearing the same references as in the first embodiment.
  • the difference lies in the fact that the sole 11 of the ski boot 6 is provided with the transverse bar or the additional pivot 24.
  • the additional transverse pivot 24 is set back from the transverse pivot 16, it is for example spaced 5 cm with the transverse pivot 16. In other words the additional pivot 24 is located further back than the first pivot 16.
  • the guide edge 21 is then segmented by a transverse slot 23b configured for the passage of the additional pivot 24.
  • the transverse slot 23 thus crosses the guide edge 21 from one side. It may be straight (not shown) or have a rounded shape large enough for the passage of the additional transverse straight bar 24.
  • the return function of the additional crossbar 24 is inactivated so that the user can continue to use shoes that have them.
  • the user can then be equipped with two pairs of skis and a single pair of corresponding shoes, a first pair of skis according to the first embodiment and a second pair of skis according to the second embodiment, the pair of shoes being able to be fixed indifferently on one or the other of the two pairs of ski.
  • the user may decide to keep his ski boots already provided with an additional crossbar for skis not having the option of the return means.
  • the binding therefore allows better guidance of the ski by optimizing the transmission of driving impulses or sensory information between the skier and the ski.
