Description

L'invention concerne une semelle pour chaussure d'athlétisme ainsi qu'une chaussure d'athlétisme comportant une telle semelle.The invention relates to a sole for athletic shoe as well as an athletic shoe comprising such a sole.

La pratique de l'athlétisme, notamment de la course à pied, impose, dans les compétitions, le port de chaussures spéciales dont les semelles présentent des saillies, ou pointes, pour assurer un bon accrochage sur la piste et une propulsion efficace.The practice of athletics, in particular running, requires, in competitions, the wearing of special shoes whose soles have protrusions, or spikes, to ensure good grip on the track and efficient propulsion.

Au cours de l'entraînement et pendant les épreuves, les pieds des coureurs, et aussi des sauteurs, développent des efforts intenses, subissent des chocs brutaux et les accidents et blessures ne sont pas rares.During the training and during the tests, the feet of the runners, and also of the jumpers, develop intense efforts, undergo brutal shocks and accidents and injuries are not uncommon.

L'apparition de pistes en matière synthétique relativement dure, pour améliorer les performances et minimiser l'effet des intempéries, rend le problème plus aigu.The appearance of relatively hard synthetic tracks, to improve performance and minimize the effect of bad weather, makes the problem more acute.

Les semelles de chaussures les plus fréquemment utilisées pour la pratique de l'athlétisme, ou chaussures à pointes, comprennent, dans un premier type, pour l'avant de la semelle,un patin qui maintient les pointes et, pour l'arrière, une demi-semelle en caoutchouc avec, ou non, une partie dans un matériau amortisseur; dans un second type, la semelle règne d'un bout à l'autre de la chaussure, maintient les pointes et comporte, ou non, au talon un matériau amortisseur.The soles of shoes most frequently used for the practice of athletics, or spiked shoes, comprise, in a first type, for the front of the sole, a shoe which maintains the spikes and, for the rear, a rubber half sole with or without a part in a shock absorbing material; in a second type, the sole reigns from one end to the other of the shoe, maintains the toes and includes, or not, a shock absorbing material at the heel.

Le patin ou la semelle est habituellement en matériau semi-rigide propre à maintenir solidement accrochées quatre ou six pointes de différentes longueurs selon la nature du terrain prévu pour la compétition, ledit matériau faisant partie du groupe comprenant de hauts polymères de polyamides, de polyesters, de polyuréthannes, naturels ou synthétiques, à dureté élevée, égale ou supérieure à 40 Shore D, et dont le module de flexion est égal ou supérieur à 400 daN/cm2.The shoe or sole is usually made of semi-rigid material capable of securely hanging four or six points of different lengths depending on the nature of the terrain provided for the competition, said material being part of the group comprising high polymers of polyamides, polyesters, polyurethanes, natural or synthetic, with high hardness, equal to or greater than 40 Shore D, and whose flexural modulus is equal to or greater than 400 daN / cm 2 .

La partie arrière de la semelle est en une ou plusieurs matières souples, choisies parmi le groupe consistant en des hauts polymères, naturels ou synthétiques, par exemple un caoutchouc de butadiène-styrène, un polyisoprène, un polybutadiène, etc., la matière formant un compact microcellulaire dont la dureté, faible, est égale ou inférieure à 80 Shore A et ayant un module de flexion égal ou inférieur à 100 daNjcm2.The rear part of the sole is made of one or more flexible materials, chosen from the group consisting of high polymers, natural or synthetic, for example butadiene-styrene rubber, polyisoprene, polybutadiene, etc., the material forming a compact microcellular whose hardness, low, is equal to or less than 80 Shore A and having a flexural modulus equal to or less than 100 daNjcm 2 .

A l'exception des pointes, la surface des patins peut être lisse ou présenter des aspérités destinées à améliorer l'accrochage sur tel ou tel type de terrain.With the exception of the tips, the surface of the pads can be smooth or have roughness intended to improve the grip on such or such type of terrain.

D'une manière générale, ces patins, en raison de leur rigidité, ne contribuent pas au confort du pied.Generally, these pads, because of their rigidity, do not contribute to the comfort of the foot.

Les dispositifs amortisseurs au talon sont notoirement insuffisants et n'évitent pas le risque de blessure.The shock absorbers in the heel are notoriously insufficient and do not avoid the risk of injury.

Egalement, malgré la présence de différentes aspérités, l'accrochage sur les différentes natures de sol n'est pas des plus satisfaisants.Also, despite the presence of different roughness, the attachment to the different types of soil is not very satisfactory.

L'invention a pour objet une semelle qui, simultanément, permet au coureur équipé de chaussures avec de telles semelles, d'accomplir des performances optimales et lui procure des conditions de confort inconnues jusqu'ici.The invention relates to a sole which, simultaneously, allows the runner equipped with shoes with such soles, to achieve optimal performance and provides him with comfort conditions unknown hitherto.

Cette semelle est caractérisée par des alternances de zones rigides et de zones souples sur la partie correspondant au patin, un coussinet amortisseur au talon, les pointes étant inclinées vers l'arrière de la chaussure et ainsi non perpendiculaires à la surface du patin.This sole is characterized by alternating rigid zones and flexible zones on the part corresponding to the shoe, a cushioning cushion in the heel, the points being inclined towards the rear of the shoe and thus not perpendicular to the surface of the shoe.

Un angle d'environ 75° avec ladite surface s'est révélé approprié.An angle of about 75 ° with said surface has been found suitable.

Les zones rigides sont destinées à recevoir et à maintenir fortement les pointes.The rigid zones are intended to receive and strongly maintain the points.

Par contre, entre chacune de ces zones, la semelle est souple, de sorte que le contact et par conséquent l'adhérence avec le sol, sont les meilleurs possibles.By cons, between each of these areas, the sole is flexible, so that the contact and therefore the grip with the ground, are the best possible.

On obtient les zones souples par une épaisseur de matière la plus petite possible; inversement une zone rigide est d'assez forte épaisseur.The flexible zones are obtained by the smallest possible thickness of material; conversely, a rigid zone is fairly thick.

Le fait d'alterner des zones souples avec des zones rigides permet un meilleur déroulement du pied. On ne s'oppose donc pas à une des fonctions principales du pied et par conséquent on améliore le confort.The fact of alternating flexible zones with rigid zones allows a better unfolding of the foot. It is therefore not opposed to one of the main functions of the foot and therefore improves comfort.

Le ou les coussinets ont pour fonction, d'une part, d'amortir les chocs ressentis par le pied lors de la reprise de contact de celui-ci avec le sol, donc d'assurer un meilleur confort et diminuer le risque d'accidents musculaires et autres blessures, d'autre part, par leur déformation, d'améliorer encore l'adhérence du patin avec le sol, donc de fournir une meilleure sécurité pour le sportif et de moins dégrader les pistes.The function of the cushion (s) is, on the one hand, to absorb the shocks felt by the foot when it resumes contact with the ground, thus ensuring better comfort and reducing the risk of accidents. muscle and other injuries, on the other hand, by their deformation, to further improve the grip of the skate with the ground, therefore to provide better security for the sportsman and to less degrade the tracks.

Les épaisseurs maximales du patin et du talon sont égales à celles des coussinets.The maximum thickness of the pad and heel are equal to that of the pads.

Celle-ci est d'environ 10 mm à l'avant et de 15 mm environ au talon.This is approximately 10 mm at the front and approximately 15 mm at the heel.

On sait que les pointes sont ordinairement orthogonales à la surface du patin. Il en résulte des incidents en ce qui concerne la liaison entre les pointes et le patin : l'effort exercé sur la pointe, lors de la course, n'est en effet pas dirigé dans l'axe de celle-ci; il se produit alors des forces tendant à arracher la pointe et son embase du patin. D'autre part, lors de la prise de contact avec le sol, les pointes, orthogonales au patin, n'entrent pas tout de suite en contact avec la piste, ce qui peut se traduire par un manque d'adhérence avec le terrain.We know that the points are usually orthogonal to the surface of the skate. This results in incidents with regard to the connection between the points and the skate: the force exerted on the point, during the race, is in fact not directed in the axis of the latter; forces then tend to tear off the point and its base from the shoe. On the other hand, when making contact with the ground, the points, orthogonal to the skate, do not immediately come into contact with the track, which can result in a lack of grip with the ground.

Le fait de donner, selon l'invention, une inclinaison à la pointe, permet de remédier à ces inconvénients; l'ensemble patin/pointes est plus résistant à l'égard des forces d'arrachement; lors de la reprise de contact du pied avec le sol, la pointe se présente verticalement à la surface dans laquelle elle doit pénétrer. Il y a donc meilleure adhésion et élimination de risques de glissade.The fact, according to the invention, an inclination at the tip, makes it possible to remedy these drawbacks; the skate / point assembly is more resistant to pull-out forces; during the resumption of contact of the foot with the ground, the point is presented vertically to the surface into which it must penetrate. There is therefore better adhesion and elimination of the risk of slipping.

Dans le cas d'une semelle selon l'invention, où le talon est réalisé dans la même matière que le patin, le talon comporte un évidement pour la mise en place d'un coussinet amortisseur et présente une surépaisseur constituée par une série de nervures inclinées qui, lors de la reprise de contact avec le sol, se couchent, ajoutant ainsi leur action à l'effet amortisseur du coussinet.In the case of a sole according to the invention, where the heel is made of the same material as the shoe, the heel has a recess for the establishment of a shock absorbing pad and has an extra thickness constituted by a series of ribs inclined which, when resumed contact with the ground, lie down, thus adding their action to the cushioning effect of the pad.

La semelle 21 (figure 1),en matière plastique à haut degré de polymérisation, a un contour 22 de forme habituelle et comprend une partie antérieure 23, une partie médiane 24 et une partie postérieure 25.The sole 21 (FIG. 1), made of plastic material with a high degree of polymerization, has a contour 22 of usual shape and includes a front part 23, a middle part 24 and a rear part 25.

Le corps 26 de la semelle 21 est souple en raison de sa minceur. A partir de sa face inférieure 27 font saillie, à la partie antérieure 23, et venus de moulage avec le corps, des bossages 28 et, à la partie postérieure 25, des reliefs rectilignes transversaux ou nervures 29, disposés parallèlement, laissant à l'extrémité postérieure une languette mince 31.The body 26 of the sole 21 is flexible because of its thinness. From its lower face 27 protrude, at the front part 23, and coming from molding with the body, bosses 28 and, at the rear part 25, transverse rectilinear reliefs or ribs 29, arranged in parallel, leaving the posterior end a thin tongue 31.

Le corps 26 présente des découpes, à savoir une découpe 32, sensiblement au centre de la partie antérieure 23 de la semelle, en forme générale de V, ou de croissant, à deux branches 33 et 34, ou cornes, et à sommet 35 tourné vers l'avant, une découpe antérieure triangulaire sensiblement isocèle 36, à angle aigu tourné vers l'avant, encadrée par deux bossages antérieurs 281 et 282, un bossage médian 283 adjacent au bord externe 37 de la semelle et trois bossages 28,, 285, 286 présents dans la zone la plus large de la partie antérieure 23, la partie antérieure 23 du corps de la semelle présentant des découpes ou ajours triangulaires isocèles 38 et 39, à angle aigu tourné vers l'avant entre, d'une part, les bossages 284 et 285 et, d'autre part, les bossages 286 et 28e.The body 26 has cutouts, namely a cutout 32, substantially in the center of the front part 23 of the sole, in the general shape of a V, or crescent, with two branches 33 and 34, or horns, and with a crown 35 turned towards the front, a substantially isosceles triangular anterior cut 36, at an acute angle turned towards the front, framed by two anterior bosses 28 1 and 28 2 , a median boss 28 3 adjacent to the external edge 37 of the sole and three bosses 28 ,, 28 5 , 28 6 present in the widest area of the front part 23, the front part 23 of the body of the sole having isosceles triangular cutouts or openings 38 and 39, at an acute angle facing forward between, on the one hand, the bosses 28 4 and 28 5 and, on the other hand, the bosses 28 6 and 28 e .

Chaque bossage est à contour polygonal, avantageusement hexagonal ou octogonal, limité par deux faces transversales parallèles 41, 42 sensiblement de même longueur, deux longues faces obliques 43, 44 légèrement divergentes à partir de la face postérieure 42 et deux ou quatre faces 45, 46 et 47, 48 (sùivant que le contour est hexagonal ou octogonal) jusqu'à la face antérieure 41. La face postérieure 42 d'un bossage est moins haute que la face antérieure 41 (figure 3), de sorte que l'embase du bossage est oblique ou bien, comme représenté, montre une face 47' horizontale, c'est-à-dire parallèle à la surface inférieure 27 du corps 26,et une face oblique 49.Each boss has a polygonal contour, advantageously hexagonal or octagonal, limited by two parallel transverse faces 41, 42 substantially the same length, two long oblique faces 43, 44 slightly divergent from the rear face 42 and two or four faces 45, 46 and 47, 48 (as long as the outline is hexagonal or octagonal) up to the front face 41. The rear face 42 of a boss is lower than the front face 41 (FIG. 3), so that the base of the boss is oblique or else, as shown, shows a horizontal face 47 ′, that is to say parallel to the lower surface 27 of the body 26, and an oblique face 49.

C'est de cette face oblique, à pente ascendante vers l'arrière lorsque la semelle est dans sa position d'utilisation, que fait saillie une pointe 51 (figure 7) dont le corps conique 52 (figure 8) se prolonge par une tige filetée 53 coopérant avec un manchon 54 taraudé intérieurement, et dépendant du fond 55 d'une cuvette métallique ou insert 56 noyé dans le bossage 26, un épaulement 57 de la pointe étant prévu au raccordement entre le corps 52 et la tige 53 qui prend appui contre la face oblique 49 dudit bossage. L'axe 58 de la pointe 51 perpendiculaire à la face oblique 49 est ainsi dirigé vers l'arrière à partir de la racine.It is from this oblique face, with an ascending slope towards the rear when the sole is in its position of use, that a point 51 protrudes (FIG. 7) whose conical body 52 (FIG. 8) is extended by a rod. threaded 53 cooperating with a sleeve 54 internally threaded, and depending on the bottom 55 of a metal bowl or insert 56 embedded in the boss 26, a shoulder 57 of the tip being provided at the connection between the body 52 and the rod 53 which is supported against the oblique face 49 of said boss. The axis 58 of the tip 51 perpendicular to the oblique face 49 is thus directed rearward from the root.

Chacune des nervures 29 est limitée par deux faces parallèles 61 et 62 (figure 3) dirigées vers l'arrière à partir de la surépaisseur 63 du corps 26 dont elle dépend et par une face frontale 64. Les nervures 29 bordent une ouverture ou ajour de talon 30 et sont perpendiculaires à la ligne moyenne 65 de la semelle.Each of the ribs 29 is limited by two parallel faces 61 and 62 (FIG. 3) directed towards the rear from the extra thickness 63 of the body 26 on which it depends and by a front face 64. The ribs 29 border an opening or opening of heel 30 and are perpendicular to the middle line 65 of the sole.

Chacun des ajours ou découpes de la semelle est prévu pour le passage d'une protubérance, à savoir une protubérance 71 (figures 4 et 5) triangulaire, de forme conjuguée de celle de la découpe 36, une protubérance 72 de forme conjuguée de la découpe 32, en forme générale de V, et des protubérances 73 et 74, triangulaires, de formes conjuguées respectivement des découpes 38 et 39.Each of the openings or cutouts of the sole is provided for the passage of a protuberance, namely a triangular protuberance 71 (FIGS. 4 and 5), of shape conjugated to that of the cutout 36, a protuberance 72 of conjugate shape of the cutout. 32, in the general shape of a V, and triangular protrusions 73 and 74, of conjugate shapes respectively of the cutouts 38 and 39.

Les protubérances 71, 72, 73 et 74 dépendent d'un flan 75, par exemple en haut polymère, mince et souple, dont le contour 76 est celui de la partie antérieure 23 du corps de semelle 26, de sorte que,lorsque les protubérances sont introduites dans les découpes conjuguées, le contour 76 est dans le prolongement du contour 22 de la semelle.The protrusions 71, 72, 73 and 74 depend on a blank 75, for example made of high polymer, thin and flexible, the contour 76 of which is that of the front part 23 of the sole body 26, so that, when the protrusions are introduced into the conjugate cutouts, the contour 76 is an extension of the contour 22 of the sole.

Les protubérances issues du flan 75 sont limitées par une paroi de même épaisseur que celui-ci, de sorte qu'elles sont souplement écrasables, leurs caractéristiques d'écrasement dépendant de leur forme. A la permanence de la forme de la protubérance la plus grande, 72, en forme de croissant, contribuent deux cloisons 77 et 78 interposées entre les parois opposées 79 et 81 limitant les branches du V.The protrusions from the blank 75 are limited by a wall of the same thickness as the latter, so that they are flexibly crushable, their crushing characteristics depending on their shape. To the permanence of the shape of the largest protuberance, 72, in the shape of a crescent, contribute two partitions 77 and 78 interposed between the opposite walls 79 and 81 limiting the branches of the V.

Lorsque les protubérances sont engagées dans les découpes correspondantes, les faces inférieures 82, 83, 84, 85 des protubérances sont à un niveau légèrement supérieur à celui des faces horizontales 47' des bossages.When the protrusions are engaged in the corresponding cutouts, the lower faces 82, 83, 84, 85 of the protrusions are at a level slightly higher than that of the horizontal faces 47 'of the bosses.

Dans la découpe 30 de talon est engagée une talonnette 91 (figures 9 et 10), en forme générale de cuvette, dont la paroi verticale 92 coopère avec le bord 90 de l'ouverture 30 et qui présente un rebord 93 dont la face inférieure 94 s'applique sur la surface supérieure de la feuille constitutive du corps de semelle 26. La hauteur du bord 92 de la cuvette est légèrement supérieure à celle des protubérances 71, 72, etc. de sorte que le talon du porteur de la chaussure est légèrement surélevé par rapport à sa plante de pied.In the heel cutout 30 is engaged a heel cup 91 (FIGS. 9 and 10), in the general shape of a bowl, the vertical wall 92 of which cooperates with the edge 90 of the opening 30 and which has a rim 93 whose bottom face 94 is applied to the upper surface of the sheet constituting the sole body 26. The height of the edge 92 of the cup is slightly greater than that of the protrusions 71, 72, etc. so that the heel of the shoe wearer is slightly raised relative to the sole of the foot.

Du fond 95 de la cuvette 91 dépendent des cloisons verticales longitudinales 96, 97, 98, 99 et transversales 101 et 102. Les cloisons 96 et 97 sont prolongées vers l'arrière par des cloisons obliques 103 et 104, la hauteur des cloisons étant légèrement inférieure à celle de la cuvette. Ces cloisons ont un rôle de raidissement. Dans une variante, la hauteur des cloisons est égale à celle de la cuvette.From the bottom 95 of the bowl 91 depend the longitudinal vertical partitions 96, 97, 98, 99 and transverse 101 and 102. The partitions 96 and 97 are extended rearwards by oblique partitions 103 and 104, the height of the partitions being slightly lower than that of the bowl. These partitions have a stiffening role. In a variant, the height of the partitions is equal to that of the bowl.

L'assemblage de la semelle est extrêmement aisé. Il suffit de présenter le flan muni de ses protubérances en face du corps 26 de la semelle à découpes et d'engager les protubérances du flan dans lesdites découpes. De même, la talonnette est présentée par sa cuvette 91 en face de la découpe 30 et est simplement enfoncée dans celle-ci, le mouvement étant limité par coopération du rebord 93 de la talonnette avec la feuille 26.The assembly of the sole is extremely easy. It suffices to present the blank provided with its protrusions in front of the body 26 of the cut-out sole and to engage the protrusions of the blank in said cutouts. Similarly, the heel piece is presented by its cup 91 opposite the cutout 30 and is simply pushed in. therein, the movement being limited by cooperation of the rim 93 of the heel piece with the sheet 26.

La chaussure à pointes comportant une telle semelle permet au coureur de tirer parti à plein de ses possibilités physiques et évite dans la plus grande mesure les accidents musculaires ou articulaires.The spiked shoe with such a sole allows the runner to take full advantage of his physical possibilities and avoids to the greatest extent muscle or joint accidents.

Les zones souples transversales ménagées par les intervalles entre les bossages permettent le libre jeu des articulations du pied.The transverse flexible zones formed by the intervals between the bosses allow the free play of the joints of the foot.

L'inclinaison vers l'arrière des pointes, de l'ordre de 75°, est favorable à la propulsion. Un bon appui est conféré par la coopération des faces horizontales des bossages avec la piste.The backward inclination of the tips, of the order of 75 °, is favorable for propulsion. Good support is provided by the cooperation of the horizontal faces of the bosses with the track.

L'action dégradante des chaussures à pointes sur la piste est réduite au minimum.The degrading action of spiked shoes on the track is reduced to a minimum.

Les protubérances souples procurent un amortissement accroissant le confort ressenti par l'athlète et conférant à la chaussure un rendement exceptionnel. De telles protubérances absorbent le choc lors de la prise de contact du pied avec le sol, et cela par une déformation progressive sous l'effet de la contrainte. Lorsque la contrainte cesse, la protubérance reprend sa forme initiale. L'air présent dans la protubérance contribue à l'absorption de l'énergie.Soft protrusions provide cushioning that increases the comfort felt by the athlete and gives the shoe exceptional performance. Such protrusions absorb the shock when the foot makes contact with the ground, and this by progressive deformation under the effect of stress. When the constraint ceases, the protuberance returns to its original form. The air present in the protuberance contributes to the absorption of energy.

Les protubérances augmentent l'adhérence de la semelle au sol, et cela par un léger effet de succion ou ventouse produit par leur déformation.The protrusions increase the grip of the sole to the ground, and this by a slight suction or suction effect produced by their deformation.

Les parties arrière des protubérances ou coussinets sont en arrière par rapport aux pointes des bossages adjacents et leur avant à l'avant de la racine des pointes. Ainsi, le pied repose d'abord sur les coussinets, et c'est seulement ensuite que les pointes ont contact avec le sol.The rear portions of the protrusions or pads are rearward relative to the points of the adjacent bosses and their fronts in front of the root of the points. Thus, the foot rests first on the pads, and it is only then that the points come into contact with the ground.

Dans la forme de réalisation montrée sur la figure 11, une protubérance ou coussinet est formé par une surépaisseur 111 d'un flan 112.In the embodiment shown in FIG. 11, a protuberance or pad is formed by an extra thickness 111 of a blank 112.

Dans la forme de réalisation montrée sur la figure 12, un tampon 113 en matière expansée souple est compris entre le flan 114 et une pausserie 115.In the embodiment shown in FIG. 12, a pad 113 of flexible expanded material is included between the blank 114 and a frame 115.

Dans la forme de réalisation montrée sur la figure 13, une protubérance 116 est définie par la paroi 117 d'un alvéole 118 que présente un flan 119, et dans l'alvéole 118 est logé un tampon 121 d'un flan 122 superposé au flan 119.In the embodiment shown in FIG. 13, a protrusion 116 is defined by the wall 117 of a cell 118 which has a blank 119, and in the cell 118 is housed a pad 121 of a blank 122 superimposed on the blank 119.

La semelle peut être fabriquée par moulage d'un haut polymère, naturel ou synthétique, du groupe comprenant les polyesters, les polyamides, les polyuréthannes.The sole can be produced by molding a high polymer, natural or synthetic, from the group comprising polyesters, polyamides, polyurethanes.

Elle peut aussi être fabriquée par moulage en double passage, les coussinets ou protubérances étant en un polymère de dureté et de module de flexion plus faibles que ceux du polymère utilisé pour le reste de la semelle.It can also be produced by double-pass molding, the pads or protuberances being made of a polymer of lower hardness and flexural modulus than those of the polymer used for the rest of the sole.

La semelle peut aussi réulter de l'assemblage des coussinets ou protubérances du corps de semelle avec les bossages par collage, soudage, à la chaleur ou aux ultrasons, etc.The sole can also result from the assembly of the pads or protrusions of the sole body with the bosses by gluing, welding, heat or ultrasound, etc.
