Sports shoe with a shoe sole with a grip

elements

The present invention relates to a sports shoe with a shoe sole with gripping elements according to the preamble of claim 1.

Such a shoe is known from DE-A-21 54 951. The retaining element there consists of a flange with a Hub that has an internal thread. This part is so inserted into a hole in the sole that the flange on rests against the inside of the sole. A retaining pin with a threaded pin of reduced diameter is attached from the outside screwed into the internal thread of the hub. As a result, a holding element screwed to the sole is formed from the outside a gripping element made of elastic material and designed as a cap is detachably attached can be. The cap can also have a metal jacket on the outside. The sole must be perforated and the holding

elements must be screwed in individually. In addition, both parts must be provided with a thread.

From GB-A-244 912 a sports shoe is known in which two plates are inserted into the sole, which has several molded retaining elements in the form of locking pins. One plate extends over the entire forefoot area to the metatarsal area and the other Plate is the size of the heel. Since the pegs must be made of hard material, this also means the sole is very inelastic. In addition, not only different plates are required for each shoe size and type of shoe can be used, but in addition, a selection of the same type of plates with a different number of Holding elements are provided. This leads to the belly high manufacturing costs. The holding elements themselves have a threaded pin on which the gripping element is attached by means of a molded threaded sleeve part is screwed on. This type of gripping element is also very expensive.

Furthermore, from US-A-30 54 197 a sports shoe is known, in which a rivet-shaped retaining member with a rivet-shaped holding element that also penetrates the sole is first of all SackTbch internal thread is inserted and by flanging the outer edge is attached. At the same time, a previously placed pressure distribution plate is riveted on. The holding member must therefore be made of metal. In the inner thread of the holding member is a with a threaded shaft provided pin can be screwed in. The pin is in the ^ ij ^ esentMchen either cylindrical and with a provided at the end thickening or it is designed wedge-shaped with an outwardly increasing radius. The spigot is therefore weakened in the area of the approach of the threaded shaft, so that there is a particular risk of breakage here. A cap, which forms the actual gripping element, is on the pin

snap-on. The inner wall of the cap is the Adapted to the outer wall of the pin. Additional, wear-resistant plate-shaped parts can be applied to the cap be. Such a tunnel training is very elaborate and expensive, also heavy due to the metal parts used and the tenons can also easily break off »

Also from DE-GM 18 88 123 is a shoe with a Known sole, the peg-shaped holding element usually with the sole, for example through Nail it on, firmly connected studs. A pressure distribution disc is applied between the studs and the sole.

On the studs, caps that increase the height of the studs are also to be pushed open and interchangeable. The caps are held by clamping, for example by sawtooth-like projections and corresponding Notches in the outer surface of the cleat, and possibly by a central pin, which is attached to a tool can be pulled out again. This measure is intended to provide a lighter, cheaper sports shah the leather studs are protected and the stud height can be easily changed.

Finally, from DE-A- 32 42 606 a sports shoe with a sole is known in which single gripping into the sole and retaining element systems are molded in. The retaining element consists of a ring with and inside Ball socket sections provided on the outside, as well as with external projections as protection against rotation. The gripping element is provided with a molded or molded-in pin, which is inserted into the inner ball socket with a ball section of the holding element engages. The whole is made of the sole material by overmolding the retaining element in the

Sole held, with a 'sealing washer provided must be so that no material penetrates into the inner ball socket of the holding element. The gripping element itself has an outer flange that rests on a thickening of the sole surface.

Apart from the fact that this is a relatively complex, composed of several complicated components Holding element-gripping element combination with an elaborate manufacturing process, can turn out to be fast Start or stop as a result of the ball socket mounting and the flange of the gripping element, which only supports the outside move this and possibly even be torn from its holder.

The object of the present invention is to be achieved, a sports shoe with a shoe sole with gripping elements of the type mentioned in such a way that one gets by with simple individual elements and that anyway loosening of the gripping elements during the use of such a sports shoe is practically impossible can be.

This object is achieved by the features specified in the characterizing part of claim 1.
