Definitions

  • the present invention relates to a set for cross-country skiing which comprises a boot and a device for fixing the front part thereof on a ski.
  • US Pat. No. 4,191,396 discloses an assembly for cross-country skiing in which the front part of the sole has a significant extension which is received in a housing of complementary shape articulated on the ski around a transverse axis. disposed at the front of the toe of the shoe.
  • an elastic locking member cooperating with the front part of the shoe so as to allow it to be automatically put into place by fitting into the retaining stirrup and to prohibit its removal under the stresses to which the boot is subjected during the use of the ski.
  • the joint thus produced allows correct heel lifting during ski walking.
  • the position of the articulation axis, in front of the sole extension and therefore well in front of the toe does not allow natural and efficient walking by the skier.
  • German patent DE-A-3,023,774 a fastening device for cross-country skiing in which the front end of the boot is held in a stirrup which itself is pivotally mounted on the ski around a transverse axis which is itself arranged just in front of the toe of the shoe, which makes it possible to a certain extent to eliminate the drawbacks due to the fixing carried out in accordance with the American patent seen previously.
  • the present invention proposes to produce an assembly for cross-country skiing in which the fitting of the boot into the binding is carried out by fitting from top to bottom, this fitting being done completely automatically, that is that is to say without manual intervention of the skier, while once the boot in place in the binding, the latter can pivot on the ski in a region close to the end of the foot, with a high amplitude.
  • the cross-country ski assembly which is the subject of the present invention, comprising a boot and a device for fixing the latter to a ski, in which the front part of the boot, present in top view, a hooking contour.
  • the fastening device comprises a retaining stirrup provided with hooking means of complementary shape, the stirrup being articulated on the ski around a transverse axis disposed just in front of the toe of the boot, a member locking mechanism urged by an elastic member being arranged to cooperate with the front part of the shoe so as to allow it to be automatically put into place by fitting into the retaining clip and to prohibit its removal under the stresses to which the shoe is subjected during the use of the ski, is characterized in that the front part of the boot has a front face inclined forwards from bottom to top, capable of pushing the member towards the front of the ski of locking during the fitting of the boot and an upper notch capable of receiving by snap-fitting a beak of the locking member after fitting of the front of the boot in the retaining clip, by engagement
  • the fixing device preferably comprises an elastically deformable element, arranged to oppose a progressively increasing resistance to the pivoting movement of the retaining stirrup. This element is preferably removable.
  • the retaining stirrup and the locking member rotate as a unit during ski touring; it is then possible to make the elastically deformable element act against the locking member to oppose the pivoting of the assembly.
  • the locking member is advantageously provided with a recess accessible by the tip of a ski pole in order to facilitate the release of the binding.
  • the ski binding device comprises a base plate 1 fixed on a ski S by means of three screws 2. It also comprises a retaining bracket 3 which is constituted a horizontal plate 4 delimited by lateral edges 5, 6, extending vertically along the edges of the ski.
  • the front edges 6 (directed to the left of the figures) are higher than the rear edges 5.
  • the rear part of the edges 6 which overhangs the edges 5 is folded at right angles towards the inside of the ski to form vertical and transverse projections 7.
  • the base plate 1 is provided with a pair of side cheeks 8, extending vertically, which the edges 6 of the stirrup 3 embrace in the manner of a yoke.
  • a transverse rod 9 crosses the cheeks 8 and the edges 6 of the stirrup 3 to serve as a pivot axis for the latter.
  • a locking member 10 in the form of a lever which is also articulated on the axis 9. It will be noted that the axis 9 is located a short distance above the ski S.
  • a bowl 11 open towards the top and towards the rear of the ski while the rear part of the lever 10 carries a prominence, or spout 12.
  • a torsion spring 13 one of the end branches of which bears against the plate 1 and the other against the lever 10. This spring biases the lever 10 to rotate it around the 'axis 9, clockwise. This pivoting is limited by the fact that the part 14 of the lever 10 which is located under the spout 12 abuts against the plague 4 of the stirrup 3, which is itself in abutment against the ski.
  • the spring 13 is located inside a cavity 15 which is isolated from the outside environment (snow, ice, mud ...) by means of two superimposed sealing tongues 16,17 formed respectively on the base plate 1 and on the locking lever 10.
  • grooves 18 are formed forming slides, arranged slightly obliquely relative to the vertical.
  • An element 19 of elastically deformable material such as synthetic rubber is inserted in the slides 18 so as to occupy the space between the cheeks 8.
  • the element 19 carries an elastic tab 20 which penetrates into a hole in base plate 1 to retain it.
  • the underside of the rear part of the elastic element 19 is hollowed out, so that this part takes the form of a tongue 21 which extends above the ski, in the direction of the locking lever 10.
  • the lateral edges 21 a of the tongue 21 are slightly longer than its central part 21 b.
  • FIGS. 3 and 4 The cross-country ski boot intended to cooperate with the binding which has just been described is shown in FIGS. 3 and 4.
  • This boot C has a front part 22 forming an integral part of the sole 23 and projecting slightly at the front of the vamp 24.
  • the front part 22, which has a height significantly greater than that of the sole 23, is hollowed out by two lateral slots 25 constituting a hooking contour intended to cooperate with the projections 7 of the binding, as will be explained further.
  • Part 22 has a front face 26 slightly sloping backwards when moving from top to bottom. On the top of the part 22 is hollowed out a central notch 27.
  • the assembly works as follows.
  • the skier To put his shoe in place in the binding, the skier has the front part 22 of his shoe above the stirrup 3 so that the slots 25 are opposite the projections 7 of the stirrup. He presses the tip of the foot down, the slots 25 engaging on the projections 7 while the inclined front face 26, which acts like a ramp, pushes the locking lever 10 forward, against the spring 13.
  • the underside 28 of the front part of the sole which is slightly recessed to compensate for the thickness of the plate 4 of the stirrup 3 comes into contact with the latter, the locking spout 12 automatically snaps into the notch 27, under the thrust of the spring 13.
  • the lifting of the heel of the skier causes the pivoting of the retaining stirrup 3 and of the locking member 10 around the axis 9, in the opposite direction to that of Clockwise.
  • the spring 13 is first stressed.
  • the front wall of the lever 10 meets the edges 21a of the tongue 21, causing their relatively easy deformation, then the tongue 21 itself, causing its progressive bending.
  • the elastic resistance opposing the lifting of the heel is therefore increasingly strong; the amplitude of lifting of the heel is limited to an angle of approximately 90 degrees, angle for which the tongue 21 is bent and compressed to the maximum.
  • the tongue 21 relaxes, helping the heel of the boot to descend onto the ski.
  • the front part of the sole has vertical sides 29 which, in the road position, are embedded between the edges 5 of the stirrup 3. Thanks to this arrangement, the shoe is perfectly maintained in the lateral direction in the stirrup 3 and ski guidance is excellent.
  • This background set is both simple and efficient.
  • the position of the pivot axis 9, just at the tip of the boot and very low on the ski is ideal.
  • the front overhang of the front part 22 is of short length and does not in any way hamper the skier in his activities other than skiing.
  • the elastic element 19 being removable, by unclipping it in the base plate 1, it is possible to replace it with another element of different hardness in order to adapt it to the style of the skier and / or to the course layout.
  • Figures 8 to 10 show another embodiment of the present fixing device.
  • an elastic member 19a which alone assumes the functions previously assigned to the elastic element 19 and the spring 13, and which, when walking, works on compression and not on bending.
  • the single elastic member 19a provided in this embodiment consists of a pad made of elastic material, for example cellular polyurethane.
  • This buffer is disposed above the base plate 1a of the corresponding device and its front end 30 is engaged inside a retaining end piece 3, integral with this base plate.
  • This elastic member tends to push the locking lever 10a into the shoe retaining position C, which makes the presence of an additional spring, such as the spring 13 provided in the previous embodiment, superfluous.
  • this elastic member also has the function of ensuring the role assigned to the elastic element 19 existing in this previous embodiment.
  • the lifting of the heel of the boot causes the retaining stirrup 3a and the locking member 10a to pivot about the axis 9a, counterclockwise. .
  • the stirrup 3a and the locking member 10a thus press on the elastic pad 19a which is compressed.
  • the elastic resistance opposing the lifting of the heel is therefore increasingly strong.
  • the elastic buffer 19a relaxes, helping the heel of the boot to descend onto the ski.
  • the release of the binding is achieved by pushing the lever 10a forward, either by hand or by pressing the tip of a stick in the bowl 11a of this lever. This maneuver is obviously carried out against the pressure exerted by the single elastic member 19a provided in this embodiment.
  • the corresponding fixing device therefore has the same operating characteristics and advantages as that shown in FIGS. 1 to 7.
