Description

La présente invention concerne une chaussure de sport à crampons et notamment une chaussure de golf.The present invention relates to a studded sports shoe and in particular a golf shoe.

Les chaussures de golf connues comportent des crampons faisant saillie sous la semelle d'usure et destinés à pénétrer dans le "green" du terrain de golf pour permettre au joueur de stabiliser son appui au sol afin que le coup puisse être assuré avec une extrême précision, sachant qu'en position fixe et pendant le lancer, les pieds du joueur se cramponnent au sol de l'intérieur vers l'extérieur pour l'un et inversement pour l'autre et ne doivent pas glisser. Il est donc nécessaire que les crampons soient solidement fixés à la chaussure et possèdent le pouvoir de pénétration le mieux approprié au "green".Known golf shoes have studs protruding under the outsole and intended to penetrate the "green" of the golf course to allow the player to stabilize his support on the ground so that the shot can be delivered with extreme precision , knowing that in a fixed position and during the throw, the feet of the player cling to the ground from the inside to the outside for one and vice versa for the other and must not slip. It is therefore necessary that the studs are securely attached to the shoe and have the most suitable penetration power for the "green".

Tant que le joueur circule sur le "green" et le "rough", les chaussures lui paraissent confortables et la marche est aisée. Par contre, lorsqu'il emprunte des parcours sur sols plus durs, tels que ceux des allées, des parkings, des salles de réunion ..., la marche est relativement pénible et maladroite, les crampons s'usent anormalement et le revêtement de ces sols perdent très rapidement leur apparence de fraîcheur et se détériorent très vite.As long as the player is on the "green" and the "rough", the shoes seem comfortable and walking is easy. On the other hand, when it takes routes on harder floors, such as those of alleys, parking lots, meeting rooms ..., the walking is relatively painful and awkward, the crampons wear abnormally and the coating of these soils very quickly lose their appearance of freshness and deteriorate very quickly.

La présente invention a pour but de remédier à ces inconvénients sans que le joueur ait à se déchausser ou à équiper ses chaussures de protections particulières.The present invention aims to remedy these drawbacks without the player having to take off his shoes or equip his shoes with special protections.

Dans ce but, l'invention fait application de crampons rétractables contre l'action d'au moins un organe élastique. Conformément à l'invention, le ou les organes élastiques de tous les crampons sont tarés pour céder à la poussée du pied sur terrain dur et résister à la réaction d'un sol relativement mou tel que le "green" d'un terrain de golf et, dans les zones où les crampons rétractables sont disposés, des protubérances, telles que des minicrampons, des barrettes ou autres, sont formées en saillie sous la semelle d'usure jusqu'au moins le niveau atteint par les crampons en position complètement rétractée.To this end, the invention applies retractable studs against the action of at least one elastic member. According to the invention, the elastic member (s) of all the studs are tared to yield to the push of the foot on hard ground and resist the reaction of a relatively soft ground such as the "green" of a golf course and, in the areas where the retractable studs are arranged, protrusions, such as mini-studs, bars or the like, are formed under the outsole to at least the level reached by the studs in the fully retracted position.

Suivant une forme de réalisation particulièrement avantageuse, chaque crampon rétractable comporte une embase taraudée montée à travers la semelle d'usure, fixée à celle-ci et délimitant un logement par lequel intervient au moins un organe élastique, l'embase taraudée coopérant avec un bouchon fileté présentant une collerette de vissage accessible de l'extérieur et constituant un guide en translation pour le crampon proprement dit qui est muni, à l'opposé de sa tête, d'un pied saillant situé dans le logement précité et prenant appui sur le ou les organes élastiques considérés.According to a particularly advantageous embodiment, each retractable clamp has a base threaded mounted through the outsole, fixed thereto and delimiting a housing through which intervenes at least one elastic member, the threaded base cooperating with a threaded plug having a screw collar accessible from the outside and constituting a guide in translation for the crampon proper which is provided, opposite its head, with a projecting foot located in the aforementioned housing and bearing on the elastic member or bodies considered.

Selon un premier mode d'exécution, l'embase taraudée est borgne pour que le logement soit fermé et contienne le ou less organes élastiques, chaque organe élastique étant une pièce en élastomère qui peut être indifféremment une pièce de révolution ayant une section cruciforme, une bille, une pastille de préférence cylindrique, un tube cylindrique, tronconique, en diabolo axé sur le crampon, et/ou un ressort qui peut être indifféremment un fil hélicoïdal tronconique, une rondelle tronconique, une rondelle étoilée ...According to a first embodiment, the threaded base is blind so that the housing is closed and contains the elastic member or parts, each elastic member being an elastomer part which can be either a part of revolution having a cruciform section, a ball, a preferably cylindrical pellet, a cylindrical, frustoconical tube, in diabolo focused on the crampon, and / or a spring which can be indifferently a frustoconical helical wire, a frustoconical washer, a star washer ...

Selon un deuxième mode d'exécution, l'embase taraudée et ouverte pour déboucher en regard d'une semelle intercalaire en mousse formant l'organe élastique précité ; la mousse élastique de la semelle intercalaire peut former un téton pénétrant dans le logement, une plaquette mobile axialemen étant de préférence interpoposée entre le téton et le pied du crampon pour diviser la pression appliquée par celui-ci.According to a second embodiment, the threaded and open base to open opposite a foam midsole forming the above-mentioned elastic member; the elastic foam of the midsole can form a stud penetrating into the housing, an axially movable plate being preferably interposed between the stud and the foot of the stud to divide the pressure applied by the latter.

Ainsi, tant que le joueur évolue sur le terrain de golf, les crampons font complètement saillie et s'accrochent parfaitement au sol. Par contre, lorsque le joueur circule sur un terrain dur, les crampons s'escamotent et les chaussures portent sur le sol par les protubérances des semelles, en ne risquant dès lors pas de détériorer les crampons et le revêtement du sol.So, as long as the player is playing on the golf course, the studs protrude completely and cling perfectly to the ground. On the other hand, when the player circulates on hard ground, the crampons retract and the shoes bear on the ground by the protuberances of the soles, thus not risking damaging the crampons and the coating of the ground.

Divers autres caractéristiques et avantages de l'invention ressortent d'ailleurs de la description détaillée qui suit.Various other characteristics and advantages of the invention will also emerge from the detailed description which follows.

Une forme de réalisation de l'objet de l'invention et des modes d'exécution sont représentés, à titre d'exemples non limitatifs, sur le dessin annexé.An embodiment of the subject of the invention and embodiments are shown, by way of examples not restrictive, in the attached drawing.

Ainsi que cela ressort clairement des figures 1 et 2, la semelle d'usure 1 de la chaussure de golf est équipée, sur le pourtour de l'avant pied 2, de cinq crampons rétractables 3 et, sur le pourtour du talon 4 de quatre crampons rétractables 3. Cette semelle présente en saillie entre les crampons 3 de l'avant-pied, des protubérances 5 et entre les crampons 3 du talon, des protubérances 6. Dans l'exemple représenté, les protubérances 5 sont des minicrampons tronconiques et les protubérances 6, des barrettes pyramidales relativement allongées. Par ailleurs, dans la partie centrale de l'avant-pied 2 délimitée par les crampons 3 et protubérances 5, est formée en saillie une protubérance étendue 7 qui, dans l'exemple représenté, est une portée ondulée.As is clear from Figures 1 and 2, the outsole 1 of the golf shoe is equipped, on the periphery of the forefoot 2, with five retractable cleats 3 and, on the periphery of the heel 4 of four retractable crampons 3. This sole projecting between the crampons 3 of the forefoot, protrusions 5 and between the crampons 3 of the heel, protrusions 6. In the example shown, the protrusions 5 are frustoconical mini-crampons and the protrusions 6, relatively elongated pyramidal bars. Furthermore, in the central part of the forefoot 2 delimited by the studs 3 and protuberances 5, an extended protuberance 7 is formed projecting which, in the example shown, is a wavy surface.

La hauteur des protubérances 5, 6 et 7 correspond à au moins celle des crampons 3 lorsqu'ils sont complètement rétractés ; de plus, le nombre, la forme et la répartition desdites protubérances sont déterminés pour que les chaussures conviennent à la marche sur terrains variés relativement durs, les crampons rétra­tés se trouvant au même niveau que les protubérances, et supportent normalement l'usure qui peut en résulter.The height of the protrusions 5, 6 and 7 corresponds to at least that of the studs 3 when they are fully retracted; in addition, the number, shape and distribution of said protrusions are determined so that the shoes are suitable for walking on various relatively hard terrains, the retracted crampons being at the same level as the protrusions, and support normally the wear that may result.

La figure 3 illustre un premier mode d'exécution particulier de l'un de ces crampons rétractables 3.FIG. 3 illustrates a first particular embodiment of one of these retractable studs 3.

Ce crampon comporte une embase 8 présentant une jupe tubulaire taraudée 9 faisant corps avec un fond 10 qui se prolonge vers la périphérie par un élément d'appui et d'ancrage 11 situé du côté de la face intérieure de la semelle 1. Dans l'exemple représenté, cet élément est une couronne annulaire munie de griffes 12 destinées à pénétrer dans la semelle d'usure 1 ; mais il est bien évident que l'élément 11 peut être constitué différemment, en particulier par un croisillon ou autre de façon que son maintien puisse être obtenu par surmoulage.This crampon comprises a base 8 having a tapped tubular skirt 9 integral with a bottom 10 which is extended towards the periphery by a support and anchoring element 11 situated on the side of the inner face of the sole 1. In the example shown, this element is an annular crown provided with claws 12 intended to penetrate into the outsole 1; but it is obvious that the element 11 can be constituted differently, in particular by a spider or the like so that its maintenance can be obtained by overmolding.

Le crampon 3 comporte également un bouchon fileté 13 susceptible de coopérer avec la jupe taraudée 9 de l'embase 8, ce bouchon présentant en saillie une collerette de vissage 14 munie de trous 15 pour la prise d'une clé à griffes. Lorsque le bouchon 13 est vissé au moyen de celle-ci dans l'embase 8, la collerette 14 est appliquée contre la surface extérieure de la semelle 1, alors que l'élément d'ancrage 11 est situé contre la surface intérieure ou dans la masse de ladite semelle.The crampon 3 also includes a threaded plug 13 capable of cooperating with the threaded skirt 9 of the base 8, this plug having a protruding screw flange 14 provided with holes 15 for taking a claw wrench. When the plug 13 is screwed by means of the latter into the base 8, the flange 14 is applied against the external surface of the sole 1, while the anchoring element 11 is situated against the internal surface or in the mass of said sole.

Le bouchon 13 délimite un alésage 16 pour le guidage précis en translation d'un corps cylindrique 17 du crampon proprement dit 18. Ce corps 17 fait saillie du bouchon pour que sa tête terminale tronconique 19 puisse se piquer dans le terrain. A l'opposé de sa tête, le corps 17 comporte un pied proéminent 20 situé dans un logement 21 délimité dans l'embase 8 entre son fond 10 et l'extrémité en regard 22 du bouchon 13. Dans l'exemple illustré par la figure 3, le pied 20 est un embout présentant un épaulement d'appui 23 butant, lorsque le crampon 18 est une position complètement saillante, contre l'extrémité 22 du bouchon.The plug 13 delimits a bore 16 for the precise guiding in translation of a cylindrical body 17 of the stud itself 18. This body 17 projects from the plug so that its frustoconical end head 19 can prick itself into the ground. Opposite its head, the body 17 has a prominent foot 20 located in a housing 21 delimited in the base 8 between its bottom 10 and the opposite end 22 of the plug 13. In the example illustrated by the figure 3, the foot 20 is an end piece having a bearing shoulder 23 abutting, when the clamp 18 is in a completely projecting position, against the end 22 of the plug.

Pour améliorer le positionnement du crampon 18 et sa tenue en position saillante, il peut être avantageux, ainsi que cela ressort de la figure 4, que le pied 20 de ce crampon présente une portée tronconique 24 destinée à venir en appui contre un siège tronconique conjugué 25 du bouchon 13.To improve the positioning of the crampon 18 and its holding in the projecting position, it may be advantageous, as is apparent from FIG. 4, that the foot 20 of this crampon has a frustoconical bearing 24 intended to come into abutment against a conjugate frustoconical seat 25 of the plug 13.

Le logement 21 contient un organe élastique indépendant désigné par la référence générale 26 (figures 3 à 7). Les organes élastiques des crampons rétractables d'une même chaussure sont tarés :
- pour céder à la poussée du pied sur terrain dur, la semelle 1 portant alors sur le sol par ses protubérances 5 à 7 et ses crampons rétractés,
- et pour résister la réaction d'un sol relativement mou tel que le "green", les crampons restant en saillie pour pénétrer et s'accrocher dans ce sol.The housing 21 contains an independent elastic member designated by the general reference 26 (Figures 3 to 7). The elastic members of the retractable crampons of the same shoe are tared:
- to yield to the push of the foot on hard ground, the sole 1 then bearing on the ground by its protuberances 5 to 7 and its retracted crampons,
- And to resist the reaction of a relatively soft soil such as the "green", the studs remaining protruding to penetrate and cling to this soil.

Ainsi que cela ressort des figures 3 à 6, l'organe élastique 26 est en un matériau élastomère (caoutchouc, polyuréthane, éthylène vinyle acétate ...) de densité appropriée, matériau qui selon la forme à obtenir est moulé, découpé ou autre.As can be seen from FIGS. 3 to 6, the elastic member 26 is made of an elastomeric material (rubber, polyurethane, ethylene vinyl acetate, etc.) of appropriate density, a material which, depending on the shape to be obtained, is molded, cut or other.

La figure 3 montre que l'organe élastique 26 est une pièce de révolution 27 présentant une section cruciforme de façon qu'elle porte contre le fond 10 et le pied 20 par des surfaces annulaires terminant des ventouses aplatissables.Figure 3 shows that the elastic member 26 is a part of revolution 27 having a cruciform section so that it bears against the bottom 10 and the foot 20 by annular surfaces ending with flattenable suction cups.

La figure 4 montre que cet organe est un tube cylindrique 28 ou tronconique 29 pouvant ou non être rempli de mousse.Figure 4 shows that this member is a cylindrical tube 28 or frustoconical 29 which may or may not be filled with foam.

La figure 5 montre que ledit organe est un tube conformé en diabolo 30 pouvant aussi être ou non rempli de mousse, la section annulaire de ce diabolo étant de préférence croissante du milieu rétréci vers les extrémités élargies.FIG. 5 shows that said member is a tube shaped as a diabolo 30 which may or may not also be filled with foam, the annular section of this diabolo preferably increasing from the narrowed medium towards the enlarged ends.

La figure 6 montre que l'organe élastique est une bille 31 ou une pastille cylindrique 32.FIG. 6 shows that the elastic member is a ball 31 or a cylindrical tablet 32.

Un exemple de dimensionnement est donné ci-après. Le logement 21 mesure, lorsque le crampon 18 fait saillie, une hauteur de 4 mm pour un diamètre de 8 mm, la course du crampon est de 3mm et la hauteur du logement lorsque le crampon est rétracté est de 1mm.An example of sizing is given below. The housing 21 measures, when the spike 18 protrudes, a height of 4 mm for a diameter of 8 mm, the travel of the spike is 3mm and the height of the housing when the spike is retracted is 1mm.

Dans ce cas, la bille 31 (figure 6) doit présenter un diamètre de 4,6 mm ; le tube cylindrique 28 (figure 4) doit présenter un diamètre extérieur de 6 mm un diamètre intérieur de 4,7 mm et une hauteur de 4,5 mm. Ces données numériques montrent qu'après montage du crampon rétractable 3 sur une semelle 1, la bille 31 et le tube cylindrique 38 sont précontraints, ce qui leur permet de maintenir le crampon 18 proprement dit en position de saillie vers l'extérieur.In this case, the ball 31 (Figure 6) must have a diameter of 4.6 mm; the cylindrical tube 28 (Figure 4) must have an outside diameter of 6 mm, an inside diameter of 4.7 mm and a height of 4.5 mm. These digital data show that after mounting the retractable stud 3 on a sole 1, the ball 31 and the cylindrical tube 38 are prestressed, which allows them to keep the stud 18 proper in the projecting position towards the outside.

Ainsi que cela ressort de la figure 7, l'organe élastique 26 est un ressort de préférence métallique. Il est constitué par un empilage de rondelles tronconiques 33 connues sous le nom de rondelles "Belleville" ; mais il est bien évident que le ressort peut être d'un autre type et par exemple constitué par au moins une rondelle étoilée, au moins un fil hélicoïdal tronconique ou autre.As shown in Figure 7, the elastic member 26 is a preferably metallic spring. It consists of a stack of frustoconical washers 33 known under the name of "Belleville" washers; but it is obvious that the spring can be of another type and for example constituted by at least one star washer, at least one frustoconical or other helical wire.

Les figures 8 et 9 illustrent un deuxième mode d'exécution de l'un des crampons rétractables 3 montés dans la semelle 1, tels que représentés sur les figures 1 et 2.FIGS. 8 and 9 illustrate a second embodiment of one of the retractable studs 3 mounted in the sole 1, as shown in FIGS. 1 and 2.

Dans ce deuxième mode d'exécution, tous les composants du crampon qui ont déjà été décrits dans le premier mode d'exécution sont désignés par le même repère. Seules les différences sont exposées dans ce qui suit. La jupe 9 de l'embase 8 ne comporte plus de fond 10, mais débouche par une ouverture 34 au-dessus de la semelle d'usure 1. En effet, cette semelle 1 est reliée par l'intermédiaire d'une semelle intercalaire 35 en mousse à la semelle première de montage 36 et c'est la mousse de ladite semelle intercalaire 35 qui doit constituer un organe élastique 37 intervenant sur le pied 20 du crampon 18 proprement dit.In this second embodiment, all of the components of the stud which have already been described in the first embodiment are designated by the same reference. Only the differences are set out in the following. The skirt 9 of the base 8 no longer has a bottom 10, but opens out through an opening 34 above the outsole 1. In fact, this sole 1 is connected by means of a midsole 35 foam to the first mounting sole 36 and it is the foam of said midsole 35 which must constitute an elastic member 37 acting on the foot 20 of the spike 18 proper.

Si l'épaisseur de la semelle intercalaire 35 est suffisante et si en regard du crampon rétractable 3 la raideur de cette mousse est appropriée à la force de rétraction nécessaire, le pied 20 du crampon 18 peut être situé sensiblement dans le même plan que l'élément saillant 11 de l'embase 8. Cette disposition est représentée en trait mixte sur la figure 8 ; elle permet d'accroître la longueur de guidage du crampon 18 dans le bouchon 13.If the thickness of the midsole 35 is sufficient and if facing the retractable spike 3 the stiffness of this foam is suitable for the retraction force required, the foot 20 of the spike 18 may be located substantially in the same plane as the protruding element 11 of the base 8. This arrangement is shown in phantom in Figure 8; it increases the guide length of the clamp 18 in the plug 13.

Mais il peut être avantageux d'accroître l'épaisseur agissante de la semelle intercalaire 35 et/ou la course utile de rétraction du crampon 18. Dans ce cas et ainsi que cela ressort de la représentation en trait plein sur la figure 8, la semelle intercalaire 35 présente un téton 38 venu de moulage en saillie inférieure pour pénétrer dans le logement 21 de l'embase 8, ce téton constituant jusqu'à la première de montage 36 l'organe élastique 37 précité.But it may be beneficial to increase the active thickness of the midsole 35 and / or the useful retraction stroke of the crampon 18. In this case and as is apparent from the representation in solid lines in FIG. 8, the midsole 35 has a stud 38 coming from molding projecting lower to enter the housing 21 of the base 8, this stud constituting until the first mounting 36 the elastic member 37 above.

En outre, si la raideur de la semelle intercalaire 35, que celle-ci soit ou non munie de tétons 37, est insuffisante pour maintenir les crampons 18 en saillie sur le "green", il peut être avantageux de diviser la pression appliquée sur la mousse par le pied 20 de chaque crampon 18, en d'autres termes de multiplier la force de rappel appliquée par ladite mousse sur ledit pied. A cet effet, et ainsi que cela ressort de la figure 9, une plaquette 39, mobile axialement dans le logement 21 de l'embase 8 , est interposée entre le pied 20 précité et la mousse de la semelle intercalaire 35 ou du téton 37 correspondant, cette mousse formant l'organe élastique 37 précité ; la surface de cette plaquette est supérieure à celle du pied 20.In addition, if the stiffness of the midsole 35, whether or not it is provided with pins 37, is insufficient to keep the studs 18 projecting from the "green", it may be advantageous to divide the pressure applied to the foam by the foot 20 of each clamp 18, in other words to multiply the restoring force applied by said foam on said foot. To this end, and as is apparent from FIG. 9, a plate 39, axially movable in the housing 21 of the base 8, is interposed between the aforementioned foot 20 and the foam of the midsole 35 or of the corresponding stud 37 , this foam forming the above-mentioned elastic member 37; the surface of this plate is greater than that of the foot 20.

La figure 10 illustre un troisième mode d'exécution de l'un des crampons rétractables 3 montés dans la semelle 1, tels que représentés sur les figures 1 et 2.FIG. 10 illustrates a third embodiment of one of the retractable studs 3 mounted in the sole 1, as shown in FIGS. 1 and 2.

Le crampon rétractable 3 de ce troisième mode d'exécution est analogue à celui du deuxième représenté sur la figure 9 et dès lors ses organes constitutifs sont désignés par les mêmes références.The retractable clamp 3 of this third embodiment is similar to that of the second shown in Figure 9 and therefore its constituent bodies are designated by the same references.

La seule différence réside dans la constitution de l'organe élastique 40 qui intervient sur le crampon 18. En effet, selon ce troisième mode d'exécution, l'organe élastique 40 est la combinaison des organes élastiques 26 et 37. La plaquette 39 sépare alors la mousse de la semelle intercalaire 35 (ou d'un téton 38), de l'empilage de rondelles "Belleville" 33 (ou de l'un quelconque des autres organes élastiques 27, 28, 29, 30, 31, 32) disposé dans le logement 21 contre le pied 20 du crampon 18.The only difference lies in the constitution of the elastic member 40 which acts on the crampon 18. In fact, according to this third embodiment, the elastic member 40 is the combination of the elastic members 26 and 37. The plate 39 separates then the foam of the midsole 35 (or of a nipple 38), of the stack of "Belleville" washers 33 (or of any of the other elastic members 27, 28, 29, 30, 31, 32) disposed in the housing 21 against the foot 20 of the stud 18.

Quel que soit le mode d'exécution choisi, le montage des crampons rétractables 3 est très facile et s'adapte à tous les modes de fabrication actuellement en pratique. Quelques exemples en sont donnés dans ce qui suit.Whatever the mode of execution chosen, the mounting retractable studs 3 is very easy and adapts to all manufacturing methods currently in practice. Some examples are given in the following.

Selon un premier exemple, lors du moulage de la semelle d'usure 1, des trous de positionnement des crampons rétractables sont ménagés. La chaussure est montée en fixant la tige sur la première et cet ensemble sur la semelle d'usure 1. Le semelage ainsi constitué est contrepercé pour faire déboucher les trous précités à l'intérieur de la chaussure. Puis les embases 8 sont emboîtées de l'intérieur dans les trous du semelage et les organes élastiques 26 sont déposés dans les logements 21 de ces embases, tandis que les bouchons 13 équipés de crampons 18 sont vissés de l'extérieur de la semelle d'usure 1 dans lesdites embases, puis bloqués au moyen d'une clé à griffes pour comprimer lesdits organes élastiques.According to a first example, during the molding of the outsole 1, positioning holes for the retractable studs are provided. The shoe is mounted by fixing the upper on the first and this assembly on the outsole 1. The sole assembly thus formed is pierced to unblock the aforementioned holes inside the shoe. Then the bases 8 are fitted from the inside into the holes in the sole assembly and the elastic members 26 are deposited in the housings 21 of these bases, while the plugs 13 fitted with studs 18 are screwed from the outside of the sole of wear 1 in said bases, then locked by means of a claw wrench to compress said elastic members.

Selon un deuxième exemple, la semelle d'usure 1, issue du moulage, est équipée de crampons rétractables tandis qu'à un autre poste, la tige est montée sur la première. Il suffit ensuite de souder la semelle d'usure équipée de crampons sous l'ensemble constitué par la tige et la première. Bien entendu, les éléments d'ancrage 11 peuvent prendre place dans des lamages de la semelle d'usure afin qu'ils affleurent la surface intérieure de celle-ci et ne forment pas des surépaisseurs sous la première.According to a second example, the outsole 1, after molding, is fitted with retractable studs while at another station, the upper is mounted on the first. Then simply weld the outsole fitted with studs under the assembly formed by the upper and the first. Of course, the anchoring elements 11 can take place in countersinks of the outsole so that they are flush with the inner surface of the latter and do not form extra thicknesses under the first.

Selon un troisième exemple dérivant du deuxième, les embases 8 des crampons sont placées dans un moule et la matière constitutive de la semelle 1 est injectée dans celui-ci, ce qui a pour effet de surmouler lesdites embases. La semelle ainsi obtenue est ensuite soudée comme dans l'exemple précédent Mais il peut être avantageux que l'injection de surmoulage soit effectuée directement sur la tige. Dans ce troisième exemple, la forme de l'élément 11 des embases peut être différente pour favoriser l'ancrage ; ainsi, l'élément 11 peut être conformé en Croix de Malte. Dans le même but et ainsi que cela ressort de la figure 9, l'embase peut présenter la forme d'une bobine dont la jupe 9 fait corps, non seulement avec un élément supérieur 11, mais également avec un élément inférieur 41, éléments qui, au lieu d'être circulaires, peuvent être polygonaux.According to a third example deriving from the second, the bases 8 of the studs are placed in a mold and the material constituting the sole 1 is injected therein, which has the effect of overmolding said bases. The sole thus obtained is then welded as in the previous example. However, it may be advantageous for the injection of overmolding to be carried out directly on the upper. In this third example, the shape of the element 11 of the bases can be different to promote anchoring; thus, element 11 can be shaped like a Maltese cross. For the same purpose and as shown in FIG. 9, the base can take the form of a coil whose skirt 9 is integral, not only with an upper element 11, but also with a lower element 41, elements which, instead of being circular, can be polygonal.

Selon un quatrième exemple, la semelle 1 est fabriquée, comme dans les deuxième et troisième exemples, pour faire corps avec les embases taraudées 8. Cette semelle est alors soudée à la tige par les techniques de mise en place d'un matériau micro-cellulaire. Dès lors, la tige et sa première sont reliées à la semelle d'usure 1 par l'intermédiaire d'une semelle intercalaire en mousse 35, constituant les organes élastiques.According to a fourth example, the sole 1 is manufactured, as in the second and third examples, to form a body with the threaded bases 8. This sole is then welded to the upper by techniques of placing a micro-cellular material . Therefore, the upper and its first are connected to the outsole 1 via a foam midsole 35, constituting the elastic members.
