Description

La présente invention concerne un crampon en matière plastique, de préférence dans toute sa masse, pour chaussure de sport (football, rugby ou autre).The present invention relates to a crampon made of plastic material, preferably in its entire mass, for sports shoes (football, rugby or other).

De tels crampons comportent généralement une tête munie de moyens de blocage en rotation et prolongée par une queue filetée; cele-ci est destinée à être vissée dans un taraudage borgne de la semelle jusqu'à ce que l'épaulement de la tête soit en appui pressant contre la surface inférieure de cette semelle, le taraudage pouvant être venu de moulage dans ladite semelle qui présente alors avantageusement un bossage saillant ou amorce de crampon ou bien ce taraudage peut être celui d'un insert métallique noyé dans la semelle lors de son moulage.Such spikes generally comprise a head provided with means of locking in rotation and extended by a threaded tail; this is intended to be screwed into a blind tapping of the sole until the shoulder of the head is pressing pressing against the lower surface of this sole, the tapping may have come from molding in said sole which has then advantageously a protruding boss or spike initiation or else this tapping can be that of a metal insert embedded in the sole during its molding.

Le joueur est amené à démonter les crampons de ses chaussures lorsqu'ils sont usés ou bien lorsqu'il juge utile de les remplacer par d'autres mieux adaptés au terrain sur lequel la partie doit se dérouler. Au cours de cette opération, il n'est pas exceptionnel que des crampons cassent au ras de la tête et de toute façon, cette casse se produit assez fréquemment pendant le jeu.The player is required to remove the studs from his shoes when they are worn or when he deems it useful to replace them with others better suited to the terrain on which the game is to be played. During this operation, it is not exceptional for crampons to break close to the head and in any case, this breakage occurs quite frequently during play.

Quelle qu'en soit la cause, la rupture d'un crampon laisse subsister dans le taraudage de la semelle la queue filetée de ce crampon; celle-ci ne fait pas saillie et il est très difficile de l'extraire. En général, le joueur est amené à confier ce travail au vendeur qui, s'il dispose d'un matériel approprié s'en charge, ou sinon, retourne la chaussure en usine. Il s'agit donc d'une réparation délicate, relativement longue, rendant la chaussure inutilisable pendant un certain temps et constituant, tant pour le fabricant que pour le détaillant, une charge coûteuse à laquelle il n'a pas été possible jusqu'à présent d'échapper.Whatever the cause, the rupture of a crampon allows the threaded tail of this crampon to remain in the thread of the sole; it does not protrude and it is very difficult to extract it. In general, the player is led to entrust this work to the seller who, if he has appropriate equipment takes care of it, or if not, returns the shoe to the factory. It is therefore a delicate repair, relatively long, rendering the shoe unusable for a certain time and constituting, both for the manufacturer and for the retailer, an expensive charge which has not been possible until now. to escape.

La présente invention a pour but de perfectionner ces crampons en rendant l'extraction de la queue filetée lorsqu'elle est cassée au ras de la semelle, facile, rapide et réalisable par le joueur lui-même sur le terrain. Concomitamment, ce perfectionnement permet d'améliorer la qualité du crampon moulé.The present invention aims to improve these studs by making the extraction of the threaded tail when it is broken flush with the sole, easy, quick and achievable by the player himself on the ground. Concomitantly, this improvement makes it possible to improve the quality of the molded stud.

Conformément à l'invention, la queue filetée du crampon délimite un conduit axial borgne dont la section est polygonale et complémentaire de celle d'une clé de desserrage, susceptible d'être utilisée, en cas de rupture du crampon, par pénétration dans l'extrémité borgne devenue libre du conduit de la queue filetée noyée dans le taraudage de la semelle elle-même ou d'un insert métallique de celle-ci.According to the invention, the threaded tail of the crampon delimits a blind axial duct whose section is polygonal and complementary to that of a loosening key, capable of being used, in the event of the crampon breaking, by penetration into the blind end that has become free from the threaded tail conduit embedded in the thread of the sole itself or of a metal insert thereof.

Suivant une forme de réalisation particulièrement avantageuse, l'extrémité borgne du conduit se trouve située au niveau de l'épaulement de la tête ou à faible profondeur dans celle-ci; l'extrémité libre du conduit débouche à l'extérieur par un chanfrein conique pour la portée étanche d'un téton du moule prévu pour le centrage du crampon lors du surmoulage de la semelle.According to a particularly advantageous embodiment, the blind end of the duct is situated at the level of the shoulder of the head or at a shallow depth therein; the free end of the conduit opens to the outside via a conical chamfer for the sealed bearing of a nipple of the mold provided for centering the crampon during overmolding of the sole.

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 est représentée, à titre d'exemple non limitatif, sur le dessin annexé. Sur ce dessin:

  • - la figure 1 est une coupe partielle montrant à grande échelle un crampon conforme à l'invention et son montage dans une semelle,
  • - la figure 2 est une coupe transversale prise suivant la ligne II-II de la figure 1.
An embodiment of the object of the invention is shown, by way of nonlimiting example, in the accompanying drawing. On this drawing:
  • FIG. 1 is a partial section showing on a large scale a crampon according to the invention and its mounting in a sole,
  • - Figure 2 is a cross section taken along line II-II of Figure 1.

Ainsi que cela ressort de la figure 1, le crampon comporte une tête 1 prolongée par une queue filetée 2, faisant saillie au delà d'une portée annulaire 3. La queue filetée 2 est destinée à être vissée dans le taraudage 4 d'un insert métallique ou autre matériau plastique 5 noyé dans et faisant corps avec un bossage 6 ou amorce de crampon venu de moulage avec la semelle 7 de la chaussure, en proéminence sur son dessous; l'insert métallique, plastique ou autre 5 est tout simplement un écrou à collerette qui se trouve parfaitement solidarisé avec la matière constituant la semelle et dont le taraudage 4 est très solide et résistant à l'usure quelle que soit la nature de cette matière constitutive de la semelle et la souplesse conférée à celle-ci. Lorsque la queue filetée 2 se trouve vissée et bloquée dans le taraudage 4 de l'insert 5 de la semelle, la portée 3 de la tête 1 est fortement serrée contre le siège également annulaire 8 du bossage 6; par ailleurs, une gorge annulaire 9 ménagée dans la portée 3 de la tête autour de la tige 2 s'emboîte parfaitement sur un bourrelet 10 de forme complémentaire faisant saillie sur ledit bossage. Bien entendu, la tête 1 présente à sa périphérie, comme celle des crampons classiques, des crans la pour la prise d'une clé de serrage creuse.As shown in Figure 1, the stud has a head 1 extended by a threaded tail 2, projecting beyond an annular bearing 3. The threaded tail 2 is intended to be screwed into the internal thread 4 of an insert metallic or other plastic material 5 embedded in and integral with a boss 6 or spike initiation molded with the sole 7 of the shoe, prominently on its underside; the metallic, plastic or other insert 5 is simply a flanged nut which is perfectly secured to the material constituting the sole and whose thread 4 is very solid and resistant to wear whatever the nature of this constituent material of the sole and the flexibility imparted thereto. When the threaded shank 2 is screwed and locked in the internal thread 4 of the insert 5 of the sole, the bearing surface 3 of the head 1 is tightly pressed against the also annular seat 8 of the boss 6; moreover, an annular groove 9 formed in the surface 3 of the head around the rod 2 fits perfectly on a bead 10 of complementary shape projecting from said boss. Of course, the head 1 has at its periphery, like that of conventional studs, notches for taking a hollow tightening key.

Suivant l'invention, on conduit axial borgne 11 se trouve ménagé dans la queue filetée 2 lors du moulage du crampon; ce conduit présente une section polygolane complémentaire de celle d'une clé de desserrage; de telles clés bien connues pour le montage des vis dites à tête six pans creux ont une section hexagonale. Bien entendu, le conduit 11 peut avoir n'importe quelle autre section du moment que celle-ci permette la transmission du couple de serrage ou de desserrage.According to the invention, a blind axial pipe 11 is formed in the threaded tail 2 during the molding of the stud; this conduit has a polygonal section complementary to that of a loosening key; such well-known keys for mounting the so-called hexagon socket head screws have a hexagonal section. Of course, the conduit 11 can have any other section as long as this allows the transmission of the tightening or loosening torque.

L'extrémité borgne 12 du conduit 11 se trouve située au niveau du fond de la gorge 9 de la tête 1 ou à faible profondeur dans celle-ci; en effet, il est important, d'une part, qu'au cours de l'usure de la tête 1 le conduit 12 ne puisse déboucher à l'extérieur et ne risque par conséquent pas de se remplir de terre ou autre matière de colmatage; d'autre part, si le crampon casse, la rupture de la tête 1 se produit généralement au ras du bourrelet annulaire 10 et il est important alors que le conduit 11 soit libre et s'ouvre sur la surface de rupture afin qu'il soit commode d'introduire dans ledit conduit la clé de serrage précitée.The blind end 12 of the conduit 11 is located at the bottom of the groove 9 of the head 1 or at a shallow depth therein; in fact, it is important, on the one hand, that during the wear of the head 1 the conduit 12 cannot open out and therefore does not risk filling up with earth or other clogging material ; on the other hand, if the crampon breaks, the rupture of the head 1 generally occurs flush with the annular bead 10 and it is important then that the conduit 11 is free and opens on the rupture surface so that it is convenient to introduce into said conduit the aforementioned tightening key.

Par ailleurs, l'extrémité libre du conduit 11 débouche à l'extérieur par un chanfrein conique 13. Ce chanfrein est utile pour la fabrication de la semelle 7; en effet, les crampons devant équiper cette semelle sont vissés par leur queue filetée dans des inserts métalliques, plastiques ou autres; la tête 1 desdits crampons est emboîtée dans l'une des moitiés du moule tandis que le chanfrein 13 de la queue filetée de ces crampons vient coiffer de façon étanche un téton de l'autre moitié du moule, téton qui est normalement prévu pour le centrage du crampon lors de la fermeture du moule avant injection et surmoulage de la semelle; ainsi, lorsque le moule est fermé, la matière d'injection ne peut pas s'infiltrer entre les chanfreins 13 et les tétons de sorte que les conduits internes 11 des crampons restent vides.Furthermore, the free end of the conduit 11 opens to the outside via a conical chamfer 13. This chamfer is useful for the manufacture of the sole 7; in fact, the studs which are to equip this sole are screwed by their threaded tail into metal, plastic or other inserts; the head 1 of said spikes is fitted into one of the halves of the mold while the chamfer 13 of the threaded tail of these spikes comes to cap a stud of the other half of the mold, a stud which is normally provided for centering the stud when closing the mold before injection and overmolding of the sole; thus, when the mold is closed, the injection material cannot infiltrate between the chamfers 13 and the pins so that the internal conduits 11 of the studs remain empty.

Ce crampon de l'invention est extrêmement avantageux tout d'abord en raison de la facilité, de la rapidité de son démontage lorsqu'il y a rupture et de la tête; il suffit de disposer d'une clé, laquelle peut être livrée en même temps que la paire de chaussures et, si elle est perdue, peut être remplacée par celle que l'on trouve dans n'importe quelle trousse à outil.This crampon of the invention is extremely advantageous first of all because of the ease, the speed of its disassembly when there is a break and of the head; all you need is a wrench, which can be delivered at the same time as the pair of shoes and, if lost, can be replaced by the one found in any tool kit.

Ce crampon est également avantageux par le fait que sa qualité est bien meilleure que celle des crampons classiques et que sa résistance est plus grande; en effet, lors du moulage par injection d'un crampon à queue filetée pleine, il se forme toujours des retassures au centre et parfois des bulles qui affaiblissent notablement la solidité de la jonction entre tête et queue; or, le conduit 11 permet, bien que ce ne soit pas sa fonction primaire, d'orienter les retassures vers le vide qu'il constitue et de la sorte la matière moulée est toujours saine et homogène; il en résulte bien entendu un accroissement de la résistance à la rupture.This crampon is also advantageous in that its quality is much better than that of conventional crampons and that its resistance is greater; indeed, during the injection molding of a stud with a full threaded tail, recesses always form in the center and sometimes bubbles which significantly weaken the solidity of the junction between head and tail; now, the conduit 11 allows, although this is not its primary function, to orient the recesses towards the vacuum which it constitutes and in this way the molded material is always healthy and homogeneous; this of course results in an increase in breaking strength.

Le crampon ne se trouve pas, contrairement aux apparences, affaibli par la présence d'un conduit puisque ce conduit se trouve situé dans l'axe de la queue filetée, c'est-à-dire dans une zone qui ne participe pratiquement pas à la résistance à la flexion et à la torsion.The crampon is not, contrary to appearances, weakened by the presence of a conduit since this conduit is located in the axis of the threaded tail, that is to say in an area which practically does not participate in resistance to bending and twisting.

L'invention n'est pas limitée à la forme de réalisation représentée et décrite en détail, car diverses modifications peuvent y être apportées sans sortir de son cadre.The invention is not limited to the embodiment shown and described in detail, because various modifications can be made without departing from its scope.
