Definitions

  • the present invention relates to a sports shoe type crampons comprising a rigid sole especially for playing football, rugby, or other.
  • the foot is for the sportsman and especially for the footballer an essential asset in the practice of his sport.
  • Two footballers can be differentiated by the quality of their pass or strike, the technique is likely to take more importance in one than the other.
  • shoes used in other sports and in particular disciplines in which great distances are covered have evolved constantly to meet the expectations of athletes.
  • many models of shoes can specifically meet the expectations of each runner and perform training and / or long-distance races with less physical fatigue. We will thus find superstring shoes, pronatrices, training shoes with a more resistant sole, very light shoes for the competition, etc.
  • the invention aims to provide a spike-type sports shoe to provide a fitting in adequacy with the great distances traveled by the athlete during training and games in order to relieve and / or preserve its health capital .
  • the invention provides a sports shoe as defined in claim 1.
  • elevation means a change in the height of a first plane relative to a second plane substantially parallel to the foreground and tangential to the front of the shoe.
  • the invention thus proposes a sports shoe with crampons, in particular for the practice of football, rugby or other sports, ensuring a rear elevation of the heel of the shoe to reduce the insidious and recurrent mechanical pathologies in sports due to current requirements .
  • the shoe according to the invention makes it possible to reduce the functional hyper-stress on the posterior muscle chain and in particular the super-Achilles plantar system by a better distribution of the load of the foot in the shoe, thus limiting the tensions and the muscular, tendinous, ligamentary and articular injuries which depend on it.
  • this functional imbalance of the suro-achille-plantar system promotes in the sportsman the regular appearance of mechanical pathologies articular, muscular, tendinous, aponeurotic or ligamentary at the level of the foot, the knee, the lower limbs, the pelvis and the back.
  • the posterior slope of the shoe makes it possible to harmonize the whole foot / shoe by considerably improving the work of the supero-Achilles-plantar system.
  • the foot performs, thanks to the invention, a functional work in synergy between the posterior motor chain and the crossed and anterior muscle chains which depend on it.
  • the longitudinal camber of the shoe resulting from the rear elevation allows to provide a faithful wrapper of the longitudinal arch of the foot.
  • This central camber allows to promote the proprioceptive stability of the arches and the elastic cushioning of the midfoot.
  • the invention thus proposes a spiked sports shoe, in particular for playing football, rugby, or other sports, ensuring a rear elevation of the heel of the shoe by means of a removable booster seat that can be replaced in a fashionable manner. simple and fast.
  • the posterior elevation created by the removable booster reduces the insidious and recurrent mechanical pathologies in sports due to current requirements.
  • the removable aspect of the booster also makes it possible to quickly and easily interchange the type of booster to bring a new technical feature to the shoe either by the establishment of a booster constituted by a material of different density or by changing the height of the booster.
  • the rapid interchangeability of the booster can simply modify the mechanical properties of the shoe by providing a sport shoe spikes scalable and perfectible adapted to adapt to the various technical, mechanical and anatomical requirements of athletes.
  • the shoe 10 according to the first embodiment of the invention and illustrated in particular by the Figures 1 and 2 , comprises a rigid outer sole 1 extending from the front to the back of the shoe 10 and secured to a footwear 11.
  • rigid sole is meant a sole which, as opposed to a flexible sole, typically a sole of a running shoe, does not allow to accompany the folding movement of the forefoot to the toes when walking. or the race.
  • the footwear 11 is able to receive and cover the entire foot 100.
  • the footwear 11 is made by means of several flexible pieces of leather, canvas or any other synthetic material known to the man of the job.
  • Each part is defined and sized to form a global plantar profile 15 providing a foot support 100 as natural as possible, thus preserving the anatomical and biomechanical balance of the athlete.
  • the outsole 1 has a plurality of studs 5 and 6 respectively distributed on the front portion 2 and the rear portion 3 of the outer sole 1.
  • the rear portion 3 has four studs 6, and the front portion 2 comprises at least four crampons 5.
  • a cleat is generally defined as an element, generally a protuberance, lining the sole of certain types of sports shoes in order to ensure better adhesion to the ground, especially on soft or grassy ground.
  • spike the various elements known to those skilled in the art to ensure better adhesion to the ground, known in particular under various names: bar, lamella, etc..
  • the crampons 5 and 6 are so-called "molded" crampons and are thus integral and made during the molding of the outer sole 1.
  • these crampons may be screwed studs of plastic or metal.
  • the crampons 5 and 6 are indifferently spikes conical, cylindrical, lamellar or any other form to ensure adhesion to the ground.
  • the whole of the outsole 1, here including the crampons 5 and 6 molded, is made of thermoplastic type plastic or thermosetting material optionally reinforced by nylon, glass or carbon type fibers, the outsole may be a overmoulding or an assembly of several materials to obtain different mechanical properties at different locations of the sole 1.
  • the front part 2 defines the part of the sole extending from the front of the shoe to the straight line L1 shown in dashed lines on the Figures 1 and 2 , corresponding substantially to the position of the most posterior crampons 5b of the plurality of crampons 5.
  • the posterior portion 3 extends from the straight line L2 shown in dotted lines on these same Figures 1 and 2 , corresponding substantially to the position of the crampons 6a the most anterior of the plurality of studs 6 to the rear of the shoe.
  • the central portion 8 is the portion extending between the anterior portion 2 and the posterior portion 3, that is to say between the lines L1 and L2.
  • the front portion 2 is a thin portion, that is to say a thickness of a few millimeters (mm), preferably less than 10 mm, of constant thickness and substantially flat.
  • the anterior portion 2 may initially include a slight bending raising the front of the front portion 2 relative to the rear of the front portion 2, so as to have a maximum of ground support during the phase digitigrade, that is to say during the period, walking or running, during which the support of the foot is conditioned on the forefoot.
  • the anterior part 2 is the part of the sole 1 supporting the forefoot and more precisely the anterior transverse arch and the anterior supports essentially formed by the head of the first metatarsal and the plantar surface of the big toe.
  • the rear part 3 of the outsole 1 is formed by a rigid upper shell 3a in contact with the footwear 11 and by a booster 4 in the lower part in contact with the ground, the booster 4 having a first portion 4a flat at the rear portion 3 and a second portion 4b extending into the central portion 8 of the sole 1.
  • the upper shell 3a has a thickness substantially constant and substantially equivalent to the thickness of the front portion 2.
  • This upper shell 3a is made of a plastic material, preferably rigid thermoplastic or thermosetting type optionally reinforced with nylon type fibers, glass or other, and forms a plane support at its upper face 3c.
  • the upper shell 3a can also extend laterally so as to form an enveloping shell 3b to optimize the maintenance and rigidity of the boot 10.
  • the booster 4 is overmolded on the upper shell 3a.
  • the booster 4 is preferably a visible outer overmoulding, the thickness of which is constant along the rear portion 3, the thickness being between 1 and 25 mm.
  • the booster 4 will have a thickness of between 10 and 15 mm in order to provide a sufficient elevation with respect to the front part 2.
  • the booster 4 has substantially the shape of a full heel, that is to say without external recess, at least in its front portion 4b and has a flat outer surface 12, this surface 12 allowing a stable support of the heel during the contact with the ground when the crampons 5 and 6 are inserted into the ground.
  • the booster 4 extends, in its portion 4b, in the central portion 8 of the sole 1.
  • the thickness of the booster 4 is bevelled in a profile 13 substantially convex so that the booster 4 maintains and strengthens the rear portion of the central portion 8 reconditioning the configuration of the supports of the medio-foot.
  • Part 4b booster enhances this area of the central portion 8 by providing additional support in the support of the midfoot.
  • the central portion 8 of the sole 1 has an outer surface profile 14 (ie: the outer plantar surface) curved and shaped vault which forms the outer longitudinal arch of the shoe.
  • This external longitudinal arch is accentuated by the difference in elevation created by the booster 4 in the rear part 3.
  • the profile 13 of the booster part 4b of the booster 4 also makes it possible to accentuate this vault-shaped curvature of the outer profile 14 of the central part 8 of the sole 1.
  • the central portion 8 of the sole 1 has an inner surface profile 16 (ie the inner plantar surface) also curved in the shape of a vault which forms the longitudinal inner arch of the shoe.
  • the curvature of the inner surface profile 16 varies along the transverse axis of the shoe in order to fit the shape of the medio foot foot vault and to support it properly.
  • the internal profile 16a of this inner surface profile 16 has a vault effect greater than its external profile 16b just like the internal arch of the midfoot which has a vault effect greater than that of its outer arch.
  • the booster 4 is typically made of a polymer material determined by the manufacturer in order to bring an additional feature to the sports shoe 10.
  • the booster 4 may be formed by overmolding a mixture of several materials to bring different properties to the outsole 1.
  • the booster 4 allows both to provide an isolated elevation of the posterior portion 3 relative to the anterior portion 2 but also provides a strategic and clever choice of a material or a mixture of materials, additional properties of stability, cushioning, absorption of shock waves and / or vibrations or elasticity, or return.
  • the booster 4 may be made of a slightly flexible and slightly deformable material, such as a reticulated foam, so as to provide a cushioning function to the shoe 1. It may further comprise air bubbles and / or springs to further enhance this cushioning function.
  • a slightly flexible and slightly deformable material such as a reticulated foam
  • the central portion 8 may also be made of a material different from the anterior portion 2 and the upper shell 3a of the rear portion 3 to provide an additional technical feature to the sports shoe, such as for example a better stability, in particular in torsion, between the anterior portion 2 and the posterior portion 3 by the use of a plastic material more rigid than the material of the outsole 1 or by the addition of an intermediate shell or an additional tongue increasing the lateral rigidity of the whole.
  • This natural camber is here accentuated by the particular shape of the central part and by that of the booster whose arrangement allows both to have an internal profile proposing a camber positioning the foot in a natural position and at the same time an arched exterior profile providing cushioning and static and dynamic support for the midfoot.
  • the particular camber of the central portion preserves the biomechanical activity of the medial arch foot to optimize the physiological qualities of the foot as a whole, that is to say, stability, absorption, elasticity, propulsion and drainage.
  • the positioning in the external situation of the booster ensures a true rear elevation of the heel of the shoe to create a difference in elevation between the rear and the front without changing the internal volume of the footwear and without weighing the shoe.
  • This external positioning also makes it possible to repackage the footwear situation in a more harmonious and physiological posture by allowing the foot to naturally find internal and external longitudinal arch that is better supported and better wrapped.
  • the isolated elevation at the rear increases the grip on the ground initially sought by cleated shoes, particularly in terms of support and acceleration.
  • the posterior booster is full, (that is to say it has no opening or external recess), and its outer surface, which can be in contact with the ground when the cleats are driven into the ground, is flat on all the posterior part of the shoe.
  • this sports shoe allows to have a stable posterior support and an efficient and homogeneous elevation on the posterior part when the crampons sink into the soft ground.
  • the shoe is distinguished from existing sports shoes, including those having isolated material additions at each rear stud that offer precarious support caused by the depression of the raised portions isolated from the crampons. Indeed, on a soft ground, the earth tends to fill all the recesses being between the posterior crampons creating an inefficient elevation of the heel and an unstable support.
  • the figure 6 represents a sports shoe 50 according to a second embodiment of the invention.
  • the shoe 50 comprises, unless otherwise indicated, all the characteristics of the sports shoe 10 described above.

  • the booster 54 also has a flat outer surface 52, this surface 52 allowing a stable support of the heel during contact with the ground when the cleats 51 and 55 are inserted into the ground.
  • the booster 54 is secured to the outer sole 58 by screwing the rear cleats 51 which each comprise a threaded rod 60.
  • the threaded rods 60 pass through corresponding bores 62 arranged in the booster 54 and are screwed inside the threaded bores 61 arranged in the outsole 58.
  • These threaded rods 60 are dimensioned so as to maintain the booster 54 in compression between the crampons 51 and the outsole 58 when these lugs 51 are screwed on this outer sole 58.
  • the length of the threaded rods 60 of the crampons 51 is of course a function of the thickness of the booster 54 used.
  • the bores inserted into the outsole 58 are preconfigured so as to receive, whatever the thickness of the booster 54 used, the same threaded rods 60.
  • the threaded rods 60 are screwed both inside the booster 54 by means of threaded bores and inside the threaded bores 61 arranged in the outer sole 58.
  • the crampons 51 are either screwed into the booster seat 54 or heat-sealed to the booster seat 54.
