Definitions

  • the present invention relates to a device for attaching a boot to a cross-country ski.
  • a cross-country binding includes a stop ensuring the blocking of the front end of the boot on the ski, while leaving the heel free, which allows the skier to take off the heels relative to the skis to achieve the movement of advance of these.
  • the present invention aims to provide a fastening device of this type, comprising improved locking means.
  • the trigger is equipped at its lower end with at least one finger turned towards the rear and intended to come to bear under the front end of the part of the shoe which fits into the stirrup.
  • the locking lever has a general U shape, the branches of which are each articulated on a branch of the stirrup, and the central part of which forms a bearing surface on the upper face of the front part of the shoe.
  • the bearing surface of the lever on the upper face of the front part of the shoe is in the form of a surface section. cylindrical with transverse axis to the ski.
  • This characteristic ensuring a support of the lever on the shoe according to a generatrix of a cylindrical surface, provides an excellent locking, whatever the inclination of the upper support face of the shoe, all the more that the device ensures a compensation for the thickness of the sole of the shoe by a more or less significant tilting of the lever.
  • the bearing surface of the front of the boot which has a cylindrical surface section of axis transverse to the ski and cooperates with a lever whose the support surface is flat.
  • the front end of the lever comprises two wings delimiting with the central part of the lever a yoke used for mounting the hinge pin of the trigger.
  • the elastic means consist of a piece of synthetic material having a general shape of U, the ends of the branches of which are articulated on the wings of the stirrup around an axis transverse to the ski, and of which the central part is supported on the front face of the lever at the trigger hinge pin thereon.
  • the elastic means consist of two strips of synthetic material arranged parallel to the axis of the ski, the ends of which are fixed on the one hand to the stirrup and on the other hand to the lever.
  • the trigger comprises a single control finger disposed on the longitudinal axis of the ski and intended to penetrate into a recess provided for this purpose in the underside of the front end of the boot.
  • the choice of the depth of this recess makes it possible to adjust the offsets at the opening and at the closing between the actuation of the trigger and the movement of fitting the shoe.
  • FIG. 1 represents a cross-country ski 2 comprising, on its upper face, a longitudinal rib 3 of trapezoidal section, crossed by a transverse axis 4 serving for the articulated mounting of the device for fixing the boot.
  • This device comprises a stirrup 5 comprising a central part parallel to the plane of the ski and two branches 6 which are perpendicular serving thereon, on the one hand for mounting the axis 4 and, on the other hand for fixing the boot.
  • the branches 6 have, on their opposite faces, two ribs 7 of generally vertical orientation when the stop is at rest, these ribs serving to fit complementary grooves 8 formed at the front end 9 of the sole of a shoe 10.
  • branches 6 of the stirrup 5 are articulated about an axis 12 transverse to the ski, the branches 13 of a lever 14 in the general shape of U whose central part has a bearing surface on the upper face 16 of the front part 9 of the shoe, in the form of a section of cylindrical surface 15.
  • the front end of the lever 14 comprises two parallel wings 17, facing forwards, used for mounting, transversely to the ski, an axis of rotation 18 of a trigger 19.
  • This trigger 19 comprises two cams 20 facing towards rear, bearing against the front edges 22 of the two branches of the stirrup, which form guide ramps.
  • the length of the cams 20 and the profile of the edges 22 are such that, when the trigger 19 is tilted forward, it drives the lever 14 in the open position and that when the trigger 19 is tilted back, it drives the lever 14 to its closed position.
  • the trigger is equipped, in its central part and at its lower end, with a finger 23 turned towards the rear. This finger is intended, when attaching the boot to the ski, to come to bear in the bottom of a recess 24 opening into the underside of the front end 9 of the boot.
  • the elastic means consist of a plastic part 25 in the general shape of a U, the ends of the arms 26 of which are mounted on the arms 6 of the stirrup with the possibility of pivoting around an axis 27 transverse to the ski, and the central part 28 of which bears on the lever 14 at the level of the articulation axis 18 of the trigger 19 on the latter.
  • the axis 27 is arranged so that the plane of action of the elastic means is located between the contact points of the cams 20 on the ramps 22 of the stirrup, respectively, in the open and closed position of the binding.
  • the user need only present his boot above the device which is in the open position as shown in FIG. 3.
  • the boot is then moved up and down. bottom to achieve the engagement of the grooves 8 on the ribs 7 of the stirrup 5, movement during which the front end of the shoe is supported on the finger 23 of the trigger 19.
  • This support causes a rearward tilting of the trigger 19 and, consequently, of the locking lever 14, this movement being favored by the action of the elastic means 25 as soon as the fulcrum of the cams 20 on the ramps 22 has passed on the other side of the plane of action of elastic means.
  • These are the elastic means which maintain the locking position of the device, shown in FIG. 4, this locking being obtained by pressing the cylindrical surface 15 of the lever 14 against the upper face 16 of the front part of the shoe.
  • the user just has to tilt the trigger forward, for example by pressing the tip of a ski pole in a recess 29 made on the trigger 19.
  • the pivoting of the trigger 19 results in the pivoting of the lever 14 towards its open position as well as in a pivoting of the finger 23 upwards, which thus ejects the shoe from the binding.
  • the end of this movement is favored by the passage on the other side of the action plan of the elastic means, which also ensure that the device is kept in the open position.
  • Figures 5 and 6 show an alternative embodiment of this device in which the same elements are designated by the same references as above, the only difference residing in the fact that the elastic means are constituted not by a stirrup-shaped part encircling the front part of the locking lever, but by two strips of synthetic material 30 arranged parallel to the axis of the ski, the ends of which are fixed, on the one hand to the arms 6 of the stirrup 5 and, on the other hand to the arms 13 of the lever 14.
  • the invention brings a great improvement to the existing technique by providing a device for attaching a boot to a ski, of simple design, with great compactness and very practical use, since allowing an automatic putting on and an ejection of the shoe during the heaving.
  • this device is not limited to the sole embodiments of this device, described above by way of examples; on the contrary, it embraces all of its variant embodiments.
  • this device could be mounted not on a ski with a longitudinal rib but on a ski of rectangular section, or even that the trigger could comprise not a central control finger, but two lateral control fingers without the 'We therefore go beyond the scope of the invention.
  • the elastic means 25 could be constituted by a torsion bar playing at the same time the role of axis 12, or by a pin spring acting between the lever 14 and the stirrup 5, or by any other mechanically known means.
