Definitions

  • the field of the invention is that of shoes, in particular sports shoes, and more particularly still sports shoes intended to cooperate with a sports machine, such as a cross-country ski, in line skate, snowshoe , etc., according to a movement in which, the tip of the shoe being secured to the machine, the heel is movable between a position in abutment on the machine and a raised position relative to said machine.
  • This movement of the foot is that which is found in particular during cross-country skiing practices in so-called "no alternative 'or" no skater "evolution techniques.
  • the essential qualities sought for shoes adapted to this kind of movement are a stiffness in transverse direction (great stiffness in torsion) combined with longitudinal flexibility, especially in the area metatarsophalangeal (low longitudinal stiffness).
  • the present invention thus relates more specifically to a reinforcement aimed at improve the mechanical qualities mentioned above.
  • Such reinforcement is advantageously intended to be a constituent element of the lower part of the shoe, in particular for sports, for example cross-country skiing.
  • a lower part conventionally comprises a sole exterior intended to cooperate with the sports machine, a first assembly, and a insole.
  • This lower part is assembled with the upper part of the shoe which includes in particular an upper, and possibly a upper.
  • the lower edge of the vamp is generally sewn and / or glued and / or welded with the outsole, as well as with the first mounting.
  • shoes especially sports shoes and more particularly cross-country skiing, are rigid or stiff in torsion with respect to the axis longitudinal of the shoe. This ensures good stability of the boot, especially in the case of cross-country skiing where the boot cooperates with the ski, this torsional stiffness ensuring optimal guidance of the ski by the shoe. In general, the torsional stiffness of a shoe makes it possible to guarantee proper guidance of the sports equipment with which it is associated.
  • the flexibility in the longitudinal direction of the sole of the shoe is desirable for walking and running, and is essential in the case of sports shoes cooperating with a machine to which it is only fixed by its front end, as for example with a cross-country ski, especially during the evolution in "not alternative".
  • the foot and the shoe must ability to wind and unwind easily and smoothly relative to the tip fixed front of the shoe.
  • the foot and the upper and lower parts (sole) of the shoe are flexed during almost all sporting activities. In practical and in the sense of this presentation, we speak of bending to evoke that which intervenes in the movement at the level of the metatarsophalangeal joint.
  • the shoe must, in its design, perfectly respect the positioning of this articulation which makes an angle of approximately 71/72 ° with the internal tangent at the foot, and which is located along this same tangent at approximately 73/74% of the total length of the foot.
  • U.S. Patent No. 5,406,723 relates to a shoe sole of cycling with a multilayer structure.
  • the latter is supposed to confer on the cycling shoe with sufficient longitudinal rigidity to withstand the curvature force exerted on the sole of the shoe when pedaling, while satisfying a constraint of lightness oh so important to relieve the efforts of the cyclist.
  • the multilayer structure of this shoe sole is constituted by a polyurethane foam core interposed between two skins each consisting of a plurality of composite layers based on glass fibers or carbon embedded in a cross-linked polymer resin matrix (resin phenolic). It is clear that such a sandwich reinforcement for an outer sole of a shoe cycling, has a stiffness in bending such that it prohibits practically any longitudinal flexion movement. This is precisely what is sought after. Therefore, such reinforcement is properly unsuitable for shoes intended to allow a movement of wound / unwound of the shoe.
  • EP n ° 0 931 470 describes a sports shoe comprising an element stiffening integrated in the lower part (sole of the shoe).
  • This stiffening element is an inner or outer sole or an internal reinforcement sandwich type comprising a core 15 made of expanded plastic foam (in light wood, in vertical plastic cylinders or in honeycomb), this core being sandwiched between two skins 13 and 14 based on polymer (nylon, polyurethane, polypropylene), resin or composite material comprising resins synthetics in which carbon fibers, aramid fibers, or glass.
  • the rigidity of the skins 13 and 14 is greater than that of the core 15.
  • the thickness of the latter is greater than that of the skins 13 and 14. It appears from FIG.
  • EP n ° 0 931 470 essentially relates to an application to shoes comprising a rigid sole, such as a bicycle, mountain shoe, etc.
  • French patent n ° 2 600 868 (86 10 130) relates to a sole of Cross-country ski boot, stiff in torsion and flexible in the longitudinal direction.
  • This sole has a reinforcement located at least in the metatarsophalangeal region and corresponding to a first assembly consisting of a composite sheet (fibers carbon or aramid glass embedded in epoxy or polyester resins).
  • This composite sheet has the characteristic of having fibers oriented in two or three directions relative to the longitudinal axis of the sole (polydirectional fabric). it is supposed to allow obtaining the desired stiffness in the longitudinal direction transverse and in torsion. There is no question of a sandwich structure in this reinforcement.
  • this shoe sole remains perfectible with regard to stiffness. cross-country skiing, flexibility, durability, lightness, performance, regularity and sensitivity of the wound / unwound movement and protection of the foot during flexions.
  • French patent application n ° 2 682 011 (91 12 376) relates to a cross-country ski boot whose torsional stiffness and longitudinal flexibility in the metatarsophalangeal zone are improved and which comprises an outer sole covered by an internal mounting first defining between them a peripheral assembly zone known as a mounting socket, making it possible to secure the upper and the upper with the lower part of the shoe.
  • the outsole has torsional stiffness properties and is mounted in combination with the first mounting made of a flexible flex material (rubber) in an area corresponding to the front part of the foot.
  • the first assembly is also made of leather or cellulose fibers in its anterior end region corresponding to the area of the knuckles, while the rear part is made for example of cardboard.
  • One of the objectives of the present invention is to provide a reinforcement of footwear, in particular a sports shoe (e.g. cross-country skiing), which provides significant advances in particular with regard to the stated technical specifications above.
  • a sports shoe e.g. cross-country skiing
  • Another objective of the invention is to propose a shoe reinforcement for cross-country skiing allowing the improvement of the performance of the driving of the ski, the durability, flexibility, weight gain, cost, foot protection, industrial feasibility.
  • Another object of the present invention is to provide a shoe, in particular sports and especially cross-country skiing, comprising a reinforcement in the sole assembly to best meet the above-mentioned specifications.
