Definitions

  • the invention relates to an improvement to cross-country ski boots.
  • each ski is launched alternately forward in two parallel rails provided for this purpose in the track.
  • the sole of which is flexible and, where appropriate, the upper secured to the sole has an external buttress. It is essential that the sole is flexible and is articulated at the tip of the boot on the upper face of the ski skate, to allow the maximum clearance of the boot relative to the ski to obtain maximum thrust and amplitude of stride. It is also important that the sole is flexible to accentuate this push.
  • the upper still attached to the sole has a semi-rigid collar hugging the bottom of the tibia, articulated on a rigid buttress placed at the malleoli to allow a transfer of impulses and push towards the ski.
  • a semi-rigid collar hugging the bottom of the tibia, articulated on a rigid buttress placed at the malleoli to allow a transfer of impulses and push towards the ski.
  • the rigid insert which occupies substantially the entire surface of the sole, is formed of two separate adjoining parts, respectively a front part, going from the tip to the arch of the foot, in which the undulations are directed transversely to give flexibility when walking, and a rear part, going from the arch to the heel, in which the undulations are inclined (arch), then perpendicularly (heel) to the previous ones, to give rigidity.
  • the junction line between the two parts causes a discontinuity in the transmission of forces, which makes it unsuitable for the practice of skating which requires a progressive succession of supports from the heel to the toe.
  • the invention overcomes these drawbacks. It aims for a cross-country ski boot adapted to the practice of skating step (skating) which first of all authorizes an ideal center of thrust for the practice of this step, namely at the level of the toes, then better support of the foot during the four phases described above, and finally better flat handling of the ski and consequently, better gliding.
  • This shoe consisting of an upper integral with a sole forming assembly, which comprises three main parts, respectively a toe and a heel, connected together by an intermediate zone corresponding to the arch of the foot, and which has two sides, respectively external and internal , arranged on either side of the longitudinal axis of the shoe, characterized in that the sole assembly comprises a reinforcing element which extends from the external face of the rear part of the heel to the face internal part of the front of the tip.
  • sole-assembly or “sole-forming assembly” is meant the assembly which cooperates with the upper to form the shoe and which comprises in particular, the sole itself, but also the first of fitting, the first of cleanliness and the buttress.
  • the characteristic reinforcing element is produced in a single piece which also forms a buttress, to be mounted just between the first mounting and the top of the sole itself.
  • Figure 1 shows a bottom view of a cross-country ski boot sole according to the invention (left foot).
  • Figure 5 is a summary perspective view before mounting of a sole according to the invention.
  • Figures 6 and 7 show a shoe viewed respectively outside right foot (Figure 6) and inside left foot (Figure 7).
  • FIG. 8 is a summary top view of the toe of an improved shoe according to the invention shown in FIG. 7.
  • Figure 9 is a schematic representation in summary perspective of a reinforcing element according to the invention also forming a buttress.
  • a cross-country ski boot essentially comprises a sole (1) and a rod (2) integral with the sole, and for the practice of skating or skating, a rigid collar (3), articulated relative to the rod (2) about an axis (4) disposed at the malleoli.
  • the shoe also includes a toe (5) and a heel (6).
  • the sole is made up (figure 1), essentially of three contiguous zones, respectively from the point (5) to the heel (6), of a point proper (A) corresponding to the front of the foot , of a heel (B), these two main parts (A) and (B) being interconnected by an intermediate zone (C) corresponding substantially to the zone of the arch of the foot, that is to say going from the metatarsals in the heel.
  • the longitudinal axis (I-I ') of the sole (1) corresponds to that of the boot and coincides with the longitudinal axis of the ski.
  • the sole (1) has towards the tip (5) an axis (7) of articulation and rotation on the binding of the ski to allow the movement of the boot relative to the ski pad.
  • the sole (1) also has one or two parallel guide grooves (8, 9) which cooperate with complementary ribs formed for this purpose on the ski runner.
  • the sole (1) also comprises a reinforcing and stiffening element designated by the general reference (10), extending from the end of the external face of the rear part (11) of the heel (B ), then diagonally and continuously (12) in the middle zone (C), and finally to the end of the internal face (13) of the front part of the tip (A).
  • this characteristic reinforcing element (10) is obtained by double molding during the manufacture of the sole. Most generally, it is therefore important that the plastic material constituting this reinforcing element (10) is more rigid, at least under the conditions of use, than the material forming the sole (1). However, if one wishes to favor comfort more than technique, it may be useful in certain embodiments, that the element (10) is slightly more flexible than the rest of the sole (1).
  • this reinforcing element (10) can be made of metal, or even of a composite material compatible with the rest of the sole.
  • the reinforcing fibers of the fibrous composite material are directed in the direction of the thrust (third phase of the movement).
  • the characteristic front (13,17) and rear (11,15) parts do not occupy all the toe or heel areas at the level of the sole, but only a minority lateral portion of this sole. , and are preferably directed parallel to the longitudinal axis (I-I ').
  • the characteristic element (10) can take on various forms shown in FIGS. 2 to 4, for example convergent (FIG. 2), divergent (FIG. 3), even sinusoidal (FIG. 4).
  • the characteristic reinforcing element (10) rises vertically at (15) on the rod (1) at the heel on the outside side and at the front at (17) at the level of the point on the interior side.
  • the parts (15 and 17) have an increased thickness relative to the rest (12) of the reinforcement.
  • the external face (15) is extended at (16) at the level of the malleoli to serve as support for the articulation axis (4) of the rigid collar (3).
  • the internal face (13) of the tip (A) rises to a height (17) corresponding in part to the thickness of the toes, then can extend (see FIG. 8) on the top and the front (18) of the shoe to cover the top of the toes in front of the toe (5) (see Figure 8), to increase the active contribution of the toes during the flight phase.
  • the skier When skiing according to the skater's step, the skier first takes support on the ski and thereby on the ground to exert its push, first on the external face (11) of the heel and thereby on the corresponding reinforcement element, continues the pushing by tilting the foot, therefore the shoe, around the axis II 'until finishing the pressing and the pushing on the internal front portion (13).
  • the characteristic reinforcing element designated by the reference (20) also forms a buttress.
  • This one-piece element (20) made of plastic by molding, comprises a base (21) intended to be inserted, in particular by gluing, under the first mounting.
  • This base (21) has openings (22) intended to receive a stiffening insert placed at the level of the arch of the foot C and openings (23) arranged in the heel B to give flexibility.
  • the one-piece element (20) rises vertically to form a first buttress (25), while on the internal face, this continuous vertical buttress extends from the heel (26) extends over the pad area (27) and ends in (28) at the front of the point (5).
  • the reference (29) designates a V-shaped slot open at the top, formed at the level of the rear part of the metatarsals, that is to say at the level of the metatarsophalangeal joint, intended to allow the flexion movements of the toes.
  • the references (30 and 31) designate an orifice molded for receiving the hinge pin (4).
  • the upward portions (25) and (28) forming the buttresses external heel (25) and internal toe (28), have an additional thickness relative to the rest of the part ( 20 ), which gives these parts greater rigidity.
  • the external face of these portions (25,28) is granite.
  • the one-piece element (20) is molded from a single plastic material, it can be molded from two materials, a more rigid material used to make the characteristic rising parts (25 and 28) and the connecting parts. .
