Definitions

  • cleat-shaped gripping element for sports shoes with the features according to the preamble, handle of claim 1.
  • cleat-shaped gripping elements are to be understood as meaning those which are used in particular on sports shoes for lawn sports and are conventionally referred to as cleats or cams. Gripping elements that are used on racing shoes (so-called spikes or spikes) should not be included here.
  • a gripping element of the type specified at the outset in which the gripping element body has a central metal part and a gripping element base which surrounds it and which can be made of plastic, and a ceramic insert forming the tread surface of the gripping element is connected directly to the lower end of the metal part by soldering or gluing is (GB-PS 12 77 684).
  • the ceramic insert is with this known gripping element a ball which is fastened in a recess at the lower end of the metal part.
  • the selected spherical shape of the ceramic insert is very sensitive to point-like impact loads due to the brittleness of the ceramic material, so that a pronounced tendency to crack or break off ceramic pieces when walking on hard floor surfaces, eg of concrete floor.
  • the invention is therefore based on the object of providing a lug-shaped gripping element of the type specified at the outset which, on the one hand, is simple and inexpensive to produce, but additionally also provides increased security against impact loads.
  • the invention thus provides two basic solutions, the first of which consists in that the ceramic insert which is glued or soldered directly to the underside of the metal part is lenticular with a curved top and bottom, the ratio of its diameter to its thickness preferably being about 2: 1 is.
  • a peripheral surface in the form of a cylindrical surface is preferably provided on the ceramic insert. It has been shown that with this shape of the ceramic insert, maximum strength can be achieved with respect to the combined loads that occur when the sports shoe is used. As is well known, internal stresses occur in ceramic parts after cooling after firing, which lead to considerable embrittlement and as a result, lead to sensitivity to impact.
  • the direct adhesive or soldered connection of the ceramic insert to the metal part results in such strength that not even a positive engagement of the ceramic insert in the metal part is required, but a flat connection is sufficient. It is important that the adhesive connection still has a certain elastic flexibility even in the hardened state. This is achieved, for example, by using epoxy resin adhesives.
  • soldering due to the thermal shock sensitivity of the ceramic materials, it may be expedient to first metallize the ceramic insert on the connecting surface and then to make the soldered connection using low-melting solders.
  • the metal part is expediently threaded see if the gripping element is to be screwed into a threaded insert of the sole as a stud, or it has a plate for direct embedding and anchoring in the sole if the gripping element is designed as cams formed integrally with the sole of the sports shoe.
  • the metal part of the gripping element essentially has the task of connecting the ceramic insert to the gripping element body. It can therefore be designed lightly and gracefully.
  • the metal part is expediently designed as a shaft, in particular if a thread is provided.
  • the metal part can, however, also be a spring, preferably a spiral spring, at the two ends of which the plates mentioned are fastened for connection to the ceramic insert or for anchoring in the sole.
  • the metal part of the gripping element does not hinder the greater flexibility desired for cams, but acts as a spring connected in parallel with the gripping element base.
  • the invention provides that the ceramic insert is formed by a plurality of individual ceramic bodies arranged closely next to one another, which are embedded in the gripping element body.
  • the ceramic bodies expediently have a spherical shape.
  • This embodiment is based on the knowledge that a plurality of separate ceramic bodies, for example up to 10, the respective contact and embedding area in the gripping element body is considerably enlarged, so that the holding forces are also increased accordingly.
  • the ratio of the load acting on each individual ceramic body to the holding force available thereon is therefore more favorable than in the case of a single one-piece ceramic insert. Consequently, in spite of the known direct embedding of the ceramic body in the gripping element body by casting or injection molding, a considerable increase in the service life can be achieved in a simple manner.
  • FIGS. 1 to 5 on an enlarged scale are consistently rotationally symmetrical in their essential parts and in their shape, so that the representation of a front view is unnecessary.
  • the rotationally symmetrical shape is not essential for the invention, but can be modified in favor of an oval design, for example.
  • the one in Fi g . 1 lug consists of a gripping element body designated as a whole by 1 and a ceramic insert 2.
  • the gripping element body 1 is in turn constructed from a gripping element base 3 and a metal part 4 in the form of a shaft which carries a thread 5 at its upper end.
  • a plate 6 is formed in one piece, which projects flange-like beyond the shaft 4 and is also curved on its underside in adaptation to the curved upper side of the ceramic insert 2.
  • the diameter of the plate 6 is approximately 76% of the diameter of the ceramic insert 2.
  • the gripping element base 3 is a separate part made of plastic, rubber, aluminum or the like, which can be plugged onto the metal shaft 4 and tightly encloses this and the plate 6. In addition, as can be seen from FIG. 1, it is supported on the ceramic insert 2 with a conical or preferably even rounded surface 8 of the ceramic insert 2 at this point. On its outer surface, the gripping element base 3 has customary notches 9 as engagement surfaces for a screwing tool, while on its support surface 10 which faces the L side of the sole (not shown), a serrated lock washer profile 11 which promotes adhesion to the sole against involuntary twisting is incorporated in a known manner.
  • the support surface 10 of the gripping element base 3 is as from Fig. 1 shows, widened relative to the lower part of the gripping element base 3.
  • the ceramic insert 2 consists for example of aluminum oxide (Al 2 O 3 ), silicon carbide (SiC) or steatite. It has the rotationally symmetrical lens shape shown in the drawing and has a ratio of its diameter to its thickness of approximately 2.1: 1.
  • the volume of the ceramic insert 2 for a practical embodiment of the stud according to FIG. 1 is approximately 0.3 cm 3 . With this design and this volume, as already described at the outset, the ceramic insert 2 is maximally resistant to the stresses that occur during use.
  • the circumferential surface 12 of the ceramic insert is cylindrical over approximately half the thickness of the ceramic insert and merges rounded into the curved upper or lower side.
  • the ceramic insert 2 is fastened to the adapted lower surface of the plate 6 by means of an epoxy resin adhesive, which still has a slight elasticity even in the hardened state, or by means of soldering. There is no connection between the conical or partially toroidal ring surface 8 and the ceramic insert 2; rather, it is only supported on the ring surface.
  • the metal shaft 4 and the associated opening of the gripping element base 3 are square, so that the metal shaft 4 can also be rotated and screwed in by rotating the gripping element base 3. It is also recommended for a firm connection of the gripping element base 3 to the metal shaft 4, for example by direct pouring or injection themselves to make the metal shaft 4 polygonal in cross section.
  • the design of the gripping element base 3 as a separate part has the advantage that the lug length can be varied overall by replacing the gripping element base with such a greater or smaller length.
  • the cam shown in FIG. 2 is integrally connected to the outsole 20, which consists, for example, of an elastomeric polyurethane, the gripping element base 23 being made of the same material as the outsole 20 and the metal shaft 24, the plate 26 located at its lower end and one at its upper end arranged embedding plate 27 encloses.
  • the ceramic insert 22 is basically strength of the same shape as the ceramic insert 2 according F. 1; its diameter / thickness ratio here is approximately 2: 1.
  • the ceramic insert 22 is also connected here either by gluing with an epoxy resin adhesive or by soldering to the underside of the plate 26.
  • FIG. 3 shows a modification of the cam according to FIG. 2 in such a way that a spiral spring 34, with its ends, takes the place of the solid metal shaft 24 a plate 36 for fixing the ceramic insert 32 or an anchoring plate 37 are connected by welding. It is understood that the plate 36 is again made of metal, while another material could be selected for the anchoring plate 37. The ceramic insert 32 is connected to the plate 36 in the same way as that described in connection with FIG. 2.
  • the unit which is already prefabricated and firmly connected from the ceramic insert 32, the spring 34 and the plates 36, 37 is placed in a casting mold for the outsole 30 and cast or injection-molded with the still flowable sole material.
  • the sole material penetrates into the interior of the spring 34 when the gripping element base 33 is formed, so that the windings thereof are completely surrounded by sole material.
  • the flexibility of the cam in the vertical (axial) direction is reduced considerably less than this applies to the cam according to FIG. 2, so that the elastic properties practically correspond to those of a cam consisting only of the sole material.
  • the cam according to FIG. 4 is basically constructed in the same way as the embodiment according to FIG. 3.
  • the type and arrangement of the spring 34a which is a conical steel-shaped spring with closed winding ends, differs.
  • the anchoring plate 37 and the plate 36 can be dispensed with.
  • the closed winding end 37a at the upper end is flowed around by the plastic material of the sole, so that a sufficient spring attachment is thereby achieved.
  • the fact that the closed winding end 37a no through is rigid plate, it can follow bending movements of the sole better.
  • the lower winding end 36a offers a sufficient metallic surface for direct connection to the ceramic insert 32a.
  • FIG. 5 shows a tunnel according to the second basic solution according to the invention described at the beginning.
  • This stud consists of a gripping element body 41 into which a screw 44, possibly provided with knurling, is directly embedded, for example cast or injected.
  • the screw 44 has a collar-like extension at its lower end, as can be seen from FIG. 5.
  • Near the tread of the. Gripping element body 41 is directly embedded in these several ceramic balls 42, which are arranged closely next to one another and are supported against one another. With their underside, the ceramic balls 42 extend into the tread of the tunnel.
  • the size of the Keramikku ELN g 42 is so selected that can be provided in the embodiment shown, eight ceramic balls 42, which after geringglagigstem wear of the gripping member body 41 forming plastic material, with their downwardly projecting surfaces of the tread surface of the lug.
  • the spherical shape instead of the spherical shape, differently designed ceramic bodies 42, e.g. cube-shaped, can be used.
  • the spherical shape proves to be advantageous because there are no engagement edges on which larger forces can build up when the stud is loaded laterally.
