Definitions

  • the present invention relates to a crampon made of plastic material, preferably in its entire mass, for sports shoes (football, rugby or other).
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the head 1 has at its periphery, like that of conventional studs, notches for taking a hollow tightening key.
  • 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.
  • the conduit 11 can have any other section as long as this allows the transmission of the tightening or loosening torque.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
