  • the third zone Z3 therefore extends partly in the fourth face F4 but also in the whole of the third face F3 as well as in two lower parts F12, F22 respectively forming two lower bands of the first face and of the second face.
  • the fourth face F4 could only include the third zone Z3.
  • thin flames formed by the first material can form in the third zone. Although these flames are visible, they do not increase the rigidity of the third zone because they have a small thickness. On the other hand, these flames make it possible to obtain good cohesion between the different plastic materials used.
  • the manufacture of the rear buttress 30 is obtained by a co-injection method also similar to the method of manufacture of the rear buttress 10 previously described. Thus, we endeavor to describe only the specificities or the differences between the manufacturing process of the rear buttress 30 and the manufacturing process of the rear buttress 10.
  • two injection nozzles positioned respectively at the upper end of the first face and of the second face are used.
  • the two injection points PI1, PI2 are positioned near the protuberances 33, 34, a short distance from the bearings 31, 32. It is thus ensured that the proportion of the first material relative to the second material is sufficiently high near the bearings.
  • two bearings 31, 32 are used.
  • the figures 6 and 7 illustrate the collar 40 according to one embodiment of the invention.
  • the collar 40 is an element of the one-piece cross-country ski boot 21, intended to surround the user's lower leg, above his ankle.
  • the collar 40 is made of a wall, the thickness of which may be of the order of a millimeter. The thickness of this wall is not necessarily uniform.
  • the collar 40 is formed by a first branch 43, a second branch 44, a rear cross member 45 and two tongues 46, 47.
  • the first branch 43 extends vertically upwards from the inner malleolus.
  • the first branch 43 forms an interior lateral part of the collar.
  • the first branch 43 comprises at its lower end the first bearing 41 as well as a first counterbore 48 intended to receive a head of the first axis 28.
  • the second branch 44 extends vertically upwards from the outer malleolus.
  • the second branch 44 forms an outer lateral part of the collar.
  • the second branch 44 comprises at its lower end the second bearing 42 as well as a second counterbore 49 intended to accommodate a head of the second axis 29 (clearly visible on the figure 11 ).
  • the first branch and the second branch extend upwards insofar as they follow the orientation of the leg itself supposed to be oriented vertically. If the user bends the ankle in one direction or another, he urges the articulation in rotation of the cross-country ski boot. In this case the first branch and the second branch are oriented upwards and forwards or upwards and backwards depending on the direction in which the ankle is bent.
  • the rear cross member 45 connects an upper end of the first branch 43 to an upper end of the second branch 44.
  • the rear cross member 45 surrounds the rear of the lower leg substantially at the height of the lower calf. Consequently, the rear cross member has a rounded shape suitable for enveloping the natural shape of the calf.
  • the rear cross member forms a middle part of the collar because it is framed transversely by the two branches 43, 44. In other words, the two lateral branches 43, 44 are interconnected by means of the rear cross member 45.
  • the two tongues 46, 47 extend longitudinally forwards respectively in the extension of the first branch 43 and of the second branch 44.
  • the two tongues can also be bent towards the median plane PM.
  • the two tongues each comprise a hole 50, 51 able to cooperate with a clamping means.
  • the tightening means may in particular be a hook-and-loop strap 52 as shown on the figure 5 .
  • the tightening means could also be, for example, a lace or a hook.
  • the collar 40 comprises three distinct zones Z1, Z2, Z3 called respectively first zone Z1, second zone Z2 and third zone Z3.
  • the three zones Z1, Z2 and Z3 of the collar 40 correspond to the same definitions as the three zones Z1, Z2, Z3 described for the rear buttresses 10, 30.
  • the first branch 43 is included in the first zone Z1. In other words, the first zone extends throughout the whole of the first branch. The first zone even extends beyond the first branch, in a part of the first tongue 46 and in a part of the rear cross member 45.
  • a lower part of the second branch 44, comprising the second bearing 42 and the counterbore 49, is included in the second zone Z2. In other words, the second zone extends only in the lower part of the second branch 44.
  • the second zone does not extend either into the second tongue 47 or into the rear cross member 45.
  • the second tongue 47 is included in the third. zone Z3.
  • the third zone Z3 extends in the whole of the second tongue 47.
  • the third zone Z3 also extends in an upper part of the second branch 44 and in a part of the rear cross member 45.
  • the first zone Z1 remains separate from the second zone Z2.
  • the first zone can extend only in a part of the first branch 43, in particular near the bearing 41.
  • the second zone can extend only in a part of the second branch 44, in particular near the bearing. 42.
  • the amount of first material in the first branch is greater than the amount of first material in the second branch. Therefore, the inner leg of the collar is more rigid than the outer leg of the collar. This branch also receives greater stresses because the amplitude of flexion of the ankle is greater inward than outward.
  • the second tongue 47 being produced only with the second material, it is also more flexible and can easily adapt to the morphology of a lower leg. In particular, it can easily be curved to wrap around the user's tibia.
  • the use of at least one tongue made only with the second material which is more flexible, makes it possible to obtain a pleasant and effective tightening around the lower leg regardless of its size.
  • the two tongues 46 and 47 can be made only with the second material, which is more flexible, and allowing better envelopment of the tibia, thus facilitating the tightening of the shoe.
  • two injection nozzles are used positioned at the height of the two bearings 41, 42.
  • the injection points PI1, PI2 are positioned vertically under the two bearings 41, 42, at the lowest points of the collar 40.
  • the first material diffuses into the collar by moving up the branches to an extent which depends on the quantity of first material injected. Although the quantity of first material is less in the second branch than in the first branch, the two bearings 41, 42 and their respective counterbores 48, 49 form part of the first zone or of the second zone and benefit from the rigidity conferred. by the first material.
  • the bearings 31, 32, 41, 42 cooperate together to form a rotating joint.
  • the rotational articulation is also particularly rigid. The lateral impulses given by the user with his leg and his foot are efficiently transmitted to the ski. Cross-country skiing can thus be guided with precision and without loss of energy.
  • the first plastic material may differ from the second plastic material by other mechanical properties.
  • the first plastic material can include self-lubricating and / or abrasion resistance properties to facilitate rotation of the collar around the rear buttress and to reduce wear.
  • the first plastic material can comprise fillers of Teflon, molybdenum, graphite or else glass or carbon fibers.
  • the first plastic material and the second plastic material may also differ from each other in other technical characteristics, such as impact resistance, the ability to thermoform (i.e. the ability to form deform when the material is heated so as to conform to the shape of the foot), the density (that is to say the density), or even by the color.
  • impact resistance i.e. the ability to form deform when the material is heated so as to conform to the shape of the foot
  • density that is to say the density
  • the side parts of a cross-country ski boot are more exposed to impact than the middle part which is protected by the cross-country ski.
  • the first material can be used only in areas where it is needed and thus reduce manufacturing costs if the first material has a higher price than the second material.
  • the median plane PM defines two left and right parts of an element which may be the rear buttress 10, 30 or the collar 40.
  • the left and right parts have a similar or similar shape.
  • the median plane PM can be a plane of symmetry of the external envelope of the element. That is to say that, by considering only the geometric shape of an element, and not the materials which constitute it, the median plane PM is a plane of symmetry of the element considered.
  • this element can be used indifferently for the manufacture of a left shoe or a right shoe. It is therefore possible to save on injection molds since a single mold can be used instead of at least two molds to manufacture an element for a left shoe and an element for a right shoe.
  • cross-country ski boot elements are often stressed asymmetrically, in particular for the practice of cross-country skiing using the skater's step technique.
  • An asymmetry of the rigidity of such an element can then be sought.
  • this asymmetry can be obtained only by adjusting the size of the first zone and of the second zone, that is to say by adjusting the quantity of first material on either side of the median plane PM.
  • the first plastic material could have a lower rigidity than the second plastic material.
  • the plastic material of greater rigidity could form the intermediate layer while the plastic material of lower rigidity would form two internal and external layers respectively in contact with the foot and with the foot. the outside of the shoe. The material of greater rigidity would thus be made invisible from the outside in the first zone Z1 and in the second zone Z2.

  • the invention there is a cross-country ski boot suitable for the so-called “traditional” technique or suitable for the so-called “skating step” technique.
  • the boot includes more rigid side parts for efficient transmission without loss of energy of the user's impulses to the ski, and a less rigid middle part allowing to increase the comfort of the user without degrading the performance of the ski. shoe.
