Definitions

  • the invention relates to a sports shoe, in particular a soccer shoe, with the features according to the preamble of claim 1.
  • a sports shoe of the aforementioned type in which the cams each consist of a protrusion integral with the outsole, the ring body received on this protrusion and a camshell also carried by the protrusion.
  • the cam shell is attached to the projection by a positive connection and is supported by the pressure-elastic ring on the underside of the outsole. It consists of a material that is considerably more wear-resistant than the outsole material and therefore has a lower elastic compliance than this.
  • the projection receiving the cam shell and the ring body is in one piece with the outsole, which is made of more easily deformable material, this projection can yield under pressure and bending loads, so that the cam designed in this way is elastic overall. This makes it possible, while maintaining the resilience of the cams typical of cam soles, to produce the outsole, which is less loaded in comparison to the tread surfaces of the cams, from a cheaper and softer material, without thereby shortening the life of the cam sole.
  • the invention has for its object to provide a cam sports shoe of the type specified above, which has the desired damping flexibility of the cams for cam shoes even when using a wear-resistant and therefore harder material for the outsole and the cam.
  • the outsole and thus also the cam projection on which the cam shell is accommodated consists of an elastic Compressible material that guarantees that the cam has an overall shock-absorbing effect despite the relative rigidity of the cam shell.
  • the outsole and the lower part of the cam body and the shaft connecting them to the outsole are made of a relatively wear-resistant and therefore less compressible material. Nevertheless, the desired flexibility of the cam is achieved overall because the connecting shaft is relatively thin overall compared to the transverse dimensions of the cam and its diameter, for example, is only a quarter of the cam diameter.
  • the resilient ring body is thus positively fixed to the cam, so that it is also possible to use materials for this which are difficult or impossible to combine with the material of the outsole.
  • materials for the ring body and the outsole that connect to one another during the casting process. This is the case, for example, with polyurethanes of different consistency, namely in a hard-wearing, wear-resistant form, in which bending elasticity is mainly present, for the outsole and the lower cam part, on the other hand in an elastomeric compressible form for the ring body.
  • the effect intended by the invention naturally depends on the ratio of the elasticity modules of the ring body or outsole material.
  • sufficient compliance of the cams is achieved if the inner diameter of the ring body and thus the diameter of the connecting shaft is only about a quarter to half the cam diameter.
  • the manufacturing process is relatively simple: Before the outsole is molded, the elastic ring bodies are inserted into the mold recesses in the mold, which form the cams. During the subsequent casting process, the flowable plastic material enters the lower part of the mold recesses through the ring body and thus forms the cam, in one piece with the outsole. It is not important that the ring body rests directly on the underside of the outsole, ie it lies in its plane. Because the flexibility of the cam is essentially determined by the ring body, this can also be arranged closer to the tread side of the cam. This places lower demands on maintaining an exact outer diameter of the ring body. In the generally weakly conical shape recess of the casting tool, the ring body automatically assumes the position corresponding to its outer diameter.
  • the athletic shoe shown in Fig. 1 e.g. a soccer shoe, has a shaft 1 and an associated outsole 2 made of a flexible material, e.g. Polyamide or polyurethane, which has a relatively high wear resistance to abrasion.
  • Cams 3 are integrally formed on the outsole 2 in a manner that becomes clearer from FIG. 2.
  • the outsole 2 has about 20 such cams 3.
  • a cam 3 which has a conical shape that tapers slightly downwards, consists essentially of a lower cam part 4, a shaft 5 connecting it to the outsole, and an annular body 6.
  • the ring body 6 consists of a pressure-elastic elastomer, for. B. a polyurethane, and has a height of about half the total height of the cam 3.
  • the inner diameter of the ring body 6 in the embodiment shown is only about half the outer diameter, so that accordingly the diameter of the connecting shaft 5 is only about half the transverse dimension corresponds to the cam 3.
  • the ring body 6 does not lie in the plane of the outsole 2, but somewhat below it, as can be seen from FIG. 2.
  • a slightly downwardly projecting base 7 is formed on the outsole 2, which merges with a round groove in the running side of the outsole 2.
  • the inner edge of the ring body 6 is strongly rounded (Fig. 2).
  • the connecting shaft 5 is arranged concentrically with the cam 3 forming a straight truncated cone.
  • a somewhat eccentric arrangement thereof is also possible, as a result of which one-sided flexibility of the cam 3 is promoted when it occurs.
  • the prefabricated ring bodies 6 are inserted into the mold recesses of a casting mold, not shown, which are intended for shaping the cams 3 and then, after the tool has been closed, flowable plastic material of the outsole 2 is injected.
  • the ring opening in the ring body 6 serves as a flow channel for the plastic material to form the lower cam part 4, which is formed in this way from the wear-resistant material of the outsole 2.
  • Each ring body is compressed somewhat by the pressure of the injection molding process, so that close contact between the top and bottom of the ring body and the adjacent surfaces of the cam 3 is ensured, even if the materials of the ring body 6 and the outsole 2 are not bonded or welded to one another come in. Deviating from the type of production described, it is also possible to cast the ring body in each case on the spot. This requires displaceable stamps of the casting tool in a known manner.
  • FIG. 3 differs from the one described above only in the course of the connecting shaft and in the correspondingly different shape of the ring body. For this reason, with the exception of these two parts, the same reference numerals are used in FIG. 3 as in FIG. 2.
  • the connecting shaft 5 ' extends at an angle different from 90 ° to the planar surfaces of the base 7 and the lower cam part 4, which lie on the upper and lower side of the annular body 6'.
  • the angle is approximately 45 °.
  • Correspondingly inclined is the bore of the ring body 6 'to the top and bottom.
  • This oblique arrangement of the connecting shaft 5 ' ensures that even with a to the axis of the cam formed as a straight truncated cone 3' concentric loading of the connecting shaft 5 'undergoes bending and therefore due to the compressive deformability of the annular body 6' a mobility of the lower cam part 4 with respect to Outsole 2 allows.
  • This embodiment is therefore particularly suitable for very wear-resistant and practically exclusively flexible, but hardly pressure-deformable materials for the outsole 2.
  • Due to the inclined arrangement of the connecting shaft 5 ' the cam 3' has a stronger tendency to dodge to one side. In order to avoid evasion of the shoe as a whole, it is expedient in this case to choose the orientation of the connecting shaft 5 'on the cams 3' of the outsole differently, so that the lateral evasive movements are compensated for.
  • the annular body 6 is shown as a plane-parallel disk. However, it is possible to choose different designs, e.g. form the top and bottom as a concave shell or cone surface. As a result, the compliance of the ring body 6 or 6 'is more pronounced in the outer region due to the greater thickness there.
  • the curvature can also, in so far as it differs from the drawing, correspond to an arc with a radius corresponding to half the height of the ring body 6.
  • Recognizable base 7 is formed by such an insert and ring body and insert must be arranged in the appropriate position in the casting tool during the manufacture of the sole.
