Abstract

An athletic shoe sole with cleats having exchangeable gripping elements designed in such a way that the gripping elements can easily be exchanged without incurring diminished stability or premature wear to the shoe sole. To this end, stud-shaped holding elements (2) are provided with a flange (3) with which they are molded into the shoe sole 1. Shoe sole (1) itself, or a portion associated therewith, forms coaxially to the stud-like holding elements (2), a minimum of one raised area (28) which surrounds at least one recess (25) between these raised areas (28) and stud shaped holding elements (2). Finally, the respective recesses (25) are engaged correspondingly shaped projecting elements (26) of the gripping elements or the gripping element components, respectively, which are in the form of caps (9).

Description

Die Vorliegende Erfindung betrifft einen Sportschuh mit einer Schuhsohle gemäß dem Oberbegriff des Anspruches 1.The present invention relates to a sports shoe with a shoe sole according to the preamble of claim 1.

Ein derartiger Sportschuh ist aus der DE-A-2 542 116 bekannt. Dort ist das Halteelement als zylindrischer Zapfen aus dem Material der Schuhsohle geformt. Die Nut ist in Form einer Gewindespirale ausgebildet und die Erhöhungen in der Kappe sind der Gewindespirale entsprechend geformte Gewindeschneiden. Das Befestigen der Kappen erfolgt daher durch einen Schraubvorgang, wobei die Haltekraft ausschließlich durch den Reibungsschluß Gewindespirale/Gewindeschneide bedingt ist. Bei der Benutzung derartiger Sportschuhe besteht daher die ernsthafte Gefahr einer Lockerung der Kappen. Dies führt dann zwangsläufig zum Abfallen der Kappen, die damit Verlorengehen.Such a sports shoe is known from DE-A-2 542 116. There, the holding element is formed as a cylindrical pin from the material of the shoe sole. The groove is in the form of a thread spiral and the elevations in the cap are thread cutting edges shaped in accordance with the thread spiral. The caps are therefore fastened by means of a screwing process, the holding force being determined solely by the frictional thread spiral / thread cutting. When using such sports shoes there is therefore a serious risk of loosening the caps. This inevitably leads to the caps falling off, which are therefore lost.

Aus der US-A-3 054 197 und der DE-A-2 154 951 ist es bekannt, das Halteelement entweder zylindrisch oder kegelstumpfförmig - und zwar mit der flächenmäßig kleineren Basis an der Schuhsohle - auszubilden. Hierbei stützt das Halteelement die Kappe nur im Kopfbereich ab, während der Schaft nicht als tragendes Teil ausgebildet ist. Sofern die Halteelemente gemäß der US-A-3 054 197 dabei in eine Gewindehülse innerhalb der Schuhsohle eingeschraubt sind, ist eine Verriegelung bzw. Sicherung der Verschraubung nicht vorgesehen.From US-A-3 054 197 and DE-A-2 154 951 it is known to design the holding element either cylindrical or frustoconical - with the smaller base on the sole of the shoe. Here, the holding element supports the cap only in the head area, while the shaft is not designed as a supporting part. If the holding elements according to US Pat. No. 3,054,197 are screwed into a threaded sleeve inside the shoe sole, locking or securing of the screw connection is not provided.

Durch die Schwächung des Halteelments im Bereich des Gewindeschaftes besteht bei diesen vorbekannten Ausführungen eine besonders große Bruchgefahr.Due to the weakening of the holding element in the area of the threaded shaft, there is a particularly high risk of breakage in these known designs.

Aus der DE-A-3 242 606 ist ein Halteelement bekannt, das bajonettartig in einen in die Schuhsohle eingeformten Haltering einsetzbar ist. Es besitzt einen zylindrischen Schaft mit am freien Ende befindlichen Ringwulst größeren Durchmessers.From DE-A-3 242 606 a holding element is known which can be inserted like a bayonet into a retaining ring molded into the sole of the shoe. It has a cylindrical shaft with a larger diameter ring bulge at the free end.

Ferner ist aus der GB-A-244 912 ein Schuh bekannt, bei dem in die Sohle zwei Platten eingelegt sind, die mehrere angeformte Halteelemente in Form von Rastzapfen aufweist. Dabei erstreckt sich die eine Platte über den gesamten Vorderfu- ßbereich bis etwa in den Mittelfußbereich und die andere Platte ist im Absatzbereich angeordnet und besitzt etwa die Größe des Absatzes. Da die an die Platten angeformten Zapfen aus hartem Material bestehen müssen, wird dadurch auch die Sohle sehr unelastisch. Außerdem müssen für unterschiedliche Schuhgrößen nicht nur Platten unterschiedlicher Größen verwendet werden, sondern zusätzlich muß auch bei gleichartigen Platten je nach Verwendungsart eine Auswahl mit einer verschiedenen Anzahl von Halteelementen bereitgestellt werden. Die Halteelemente selbst besitzen Gewindezapfen, auf die die Greifelemente mittels eines angeformten Gewindehülsenteils aufgeschraubt werden. Auch die Verwendung dieser Art von Greifelementen ist sehr kostspielig und wenig effektiv.Furthermore, a shoe is known from GB-A-244 912, in which two plates are inserted in the sole, which have a plurality of molded-on holding elements in the form of locking pins. One plate extends over the entire forefoot area to approximately the midfoot area and the other plate is arranged in the heel area and has approximately the size of the heel. Since the pegs formed on the plates have to be made of hard material, the sole is also very inelastic. In addition, not only plates of different sizes have to be used for different shoe sizes, but also a selection with a different number of holding elements must also be provided for plates of the same type, depending on the type of use. The holding elements themselves have threaded pins onto which the gripping elements are screwed by means of a molded-on threaded sleeve part. The use of this type of gripping elements is also very expensive and ineffective.

Mit der vorliegenden Erfindung soll die Aufgabe gelöst werden, einen Sportschuh mit einer auswechselbare Greifelemente aufweisenden Schuhsohle der eingangs erwähnten Art so auszubilden, daß die Greifelemente leicht auswechselbar sind und insbesondere eine Verminderung der Festigkeit der die Greifelemente tragenden Schuhsohle oder gar deren Beschädigung mit Sicherheit vermieden wird. Darüber hinaus soll aber auch sichergestellt sein, daß an den Greifelementen keine übermäßig hohen Flächenbelastungen auftreten. Vielmehr sollen diese Flächenbelastungen gleichmäßig über die Halteelemente verteilt werden.With the present invention, the object is to be achieved to design a sports shoe with a replaceable gripping element shoe sole of the type mentioned in such a way that the gripping elements are easily exchangeable and in particular a reduction in the strength of the shoe sole carrying the gripping elements or even their damage is avoided with certainty . In addition, however, it should also be ensured that no excessively high surface loads occur on the gripping elements. Rather, these surface loads should be distributed evenly over the holding elements.

Gemäß der vorliegenden Erfindung wird diese Aufgabe durch die im Kennzeichen des Anspruches 1 angegebenen Merkmale gelöst.According to the present invention, this object is achieved by the features specified in the characterizing part of claim 1.

Durch die kegelstumpfförmige Ausbildung des Halteelements wird erreicht, daß die Mantelfläche erheblich zur Abstützung des korrespondierenden Greifelements beiträgt. Diese Form bedingt auch eine größere mechanische Festigkeit als eine zylindrische oder eine umgekehrt kegelstumpfförmige Form mit der schmäleren Basis an der Schuhsohle. Durch die Ringnut im Ha!teele- ment und die Ringrippe im Greifelement wird ein guter, sicherer Sitz des Greifelements erreicht und dieses ist trotzdem leicht montierbar und demontierbar. Schließlich ist durch die Ausbildung der Halteelemente als selbständige Bauteile und deren Einformung in die Schuhsohle die Möglichkeit gegeben, das Halteelement aus einem Material mit geeigneter, beispielsweise zähelastischer Festigkeit herzustellen und einfach mit der Schuhsohle zu verbinden.The frustoconical design of the holding element ensures that the lateral surface contributes significantly to supporting the corresponding gripping element. This shape also requires greater mechanical strength than a cylindrical or an inverted frustoconical shape with the narrower base on the sole of the shoe. The ring groove in the holding element and the ring rib in the gripping element ensure a good, secure fit of the gripping element, which is nevertheless easy to assemble and disassemble. Finally, the design of the holding elements as independent components and their molding into the shoe sole make it possible to produce the holding element from a material with a suitable, for example tough, elastic strength and to simply connect it to the shoe sole.

Mit der Erfindung erhält man eine dauerhafte Befestigung der Greifelemente an der Sohle. Es werden hierbei keine Gewinde innerhalb der Sohle benötigt. Das Anbringen einer besonderen Druckverteilungsplatte entfällt. Durch die Erhöhungen an der Sohle wird nicht nur eine Schwächung derselben vermieden, sondern man erhält zugleich eine bessere Verankerung der Kappe in der dadurch gebildeten Vertiefung und einen festeren Sitz der Kappen an den zapfenförmigen Halteelementen.With the invention, a permanent attachment of the gripping elements to the sole is obtained. No threads are required inside the sole. There is no need to attach a special pressure distribution plate. The raised areas on the sole not only avoid weakening the sole, but at the same time result in better anchoring of the cap in the depression formed thereby and a firmer fit of the caps on the peg-shaped holding elements.

In Figur 1 ist mit 1 eine Schuhsohle, insbesondere die Laufsohle eines Sportschuhes, beispielsweise eines Fußball-, Hockey- oder Feldhandballschuhes bezeichnet. Diese besteht im allgemeinen aus einem einzigen Teil aus gespritztem oder gegossenem Kunststoff, wie Polyurethan, Polyäthylen, Polyamid, HexamethylendiaminAdipinsäure-Polykondensat oder dgl. und erstreckt sich über die gesamte Sohle, also bis zur Ferse. Es können aber auch Absatz und Sohlenteil aus zwei getrennten Teilen bestehen, wobei dann in jedem dieser Teile die weiter unten näher beschriebenen zapfenförmigen Halteelemente - nachfolgend vereinfacht als Zapfen bezeichnet - vorgesehen sind. Die Verteilung der Zapfen erfolgt in an sich bekannter Weise, beispielsweise nach Belastungsprofil der Sohle und/oder erforderlicher Griffigkeit des Sportschuhes auf einem Spielfeld.In FIG. 1, 1 denotes a shoe sole, in particular the outsole of a sports shoe, for example a soccer, hockey or field handball shoe. This generally consists of a single part made of injection-molded or cast plastic, such as polyurethane, polyethylene, polyamide, hexamethylene diamine adipic acid polycondensate or the like, and extends over the entire sole, that is to the heel. However, the heel and the sole part can also consist of two separate parts, in which case the peg-shaped holding elements described in more detail below - hereinafter simply referred to as pegs - are provided in each of these parts. The tenons are distributed in a manner known per se, for example according to the load profile of the sole and / or the required grip of the sports shoe on a playing field.

In die Laufsohle 1 ist ein Halteelement 2 oder Zapfen 1 mittels eines an ihm angebrachten Flansches 3 fest eingespritzt oder eingegossen. Vorzugsweise sind im Flansch 3 Aussparungen 4, beispielsweise in Form von Durchbrüchen vorgesehen, um eine gute Verankerung des Zapfenflansches 3 mit dem Sohlenmaterial zu gewährleisten.A holding element 2 or pin 1 is firmly injected or cast into the outsole 1 by means of a flange 3 attached to it. Recesses 4, for example in the form of openings, are preferably provided in the flange 3 in order to ensure good anchoring of the tenon flange 3 with the sole material.

Der Zapfen 2 überragt die Sohlenlauffläche 5. Er ist vorzugsweise als Kegelstumpf ausgebildet, wobei die breitere Basis der Schuhsohle 1 zugewandt ist. Der Außenmantel 6 des Zapfens 2 ist mit zumindest einer, vorzugsweise aber mit zwei im Abstand voneinander vorgesehenen Nuten 7 und 8 versehen, die günstigerweise die Form von umlaufenden Ringnuten aufweisen.The pin 2 projects beyond the sole tread 5. It is preferably designed as a truncated cone, the broader base facing the shoe sole 1. The outer jacket 6 of the pin 2 is provided with at least one, but preferably with two spaced-apart grooves 7 and 8, which advantageously have the shape of circumferential annular grooves.

Auf den Zapfen 2 ist eine Kappe 9 aus elastischem, vorzugsweise federelastischem Material, wie beispielsweise Polyäthylen, Polyurethan, Polyimid oder dgl. aufgeschnappt. Die Aussparung 10 der Kappe 9 ist der Außenkontur des Zapfens 2 weitestgehend identisch, angepaßt. Sie kann jedoch geringfügig kleiner sein als der Zapfen 2, so daß die Kappe 9 unter Vorspannung mit dem Zapfen 2 verrastet. Zur Erhöhung der Abriebfestigkeit der Kappe 9 ist bzw. sind die Trittfläche 11 oder der ganze Greifbereich, also auch seitliche Wandungsteile eines Kappenteiles 9a mit einem abriebfesten Werkstoff bedeckt, beispielsweise mit einer konischen Platte oder Kuppe 12 aus Metall, wie Aluminium, Stahl, Messing, Kupfer, Bronce oder dgl. oder aus Leder oder aus Keramik, wie Aluminiumoxyd, Steatit, Zirkondioxyd, Korund oder dgl. Die Platte oder Kuppe 12 kann aufgeklebt sein oder sie kann Steck- und/oder Rastelemente 13, beispielsweise in Form von Bolzen oder Bohrungen aufweisen, mit denen sie in den entsprechend geformten Kappenteil 9a eingesteckt oder eingerastet und eventuell zusätzlich verklebt werden kann.A cap 9 made of an elastic, preferably resilient material, such as polyethylene, polyurethane, polyimide or the like, is snapped onto the pin 2. The recess 10 of the cap 9 is largely identical, adapted to the outer contour of the pin 2. However, it can be slightly smaller than the pin 2, so that the cap 9 latches with the pin 2 under pretension. To increase the abrasion resistance of the cap 9, the tread surface 11 or the entire gripping area, that is also the lateral wall parts of a cap part 9a, is covered with an abrasion-resistant material, for example with a conical plate or dome 12 made of metal, such as aluminum, steel, brass, Copper, bronze or the like. Or made of leather or ceramic, such as aluminum oxide, steatite, zirconium dioxide, corundum or the like. The plate or dome 12 can be glued on or it can have plug-in and / or locking elements 13, for example in the form of bolts or bores have with which it can be inserted or locked in the correspondingly shaped cap part 9a and possibly additionally glued.

Die Verrastung der elastischen Kappe 9 bzw. des elastischen Kappenteiles 9a erfolgt über in der Aussparung 10 vorhandene Rippen 14, 15, vorzugsweise Ringrippen, die mit den, Nuten 7, 8, vorzugsweise Ringnuten, des Zapfens 2 korrespondieren und insbesondere im Querschnitt gegengleich zum Querschnitt der Ringnuten 7, 8 ausgebildet sind.The latching of the elastic cap 9 or of the elastic cap part 9a takes place via ribs 14, 15, preferably ring ribs, which are present in the recess 10 and which correspond to the grooves 7, 8, preferably ring grooves, of the pin 2 and in particular in cross section in comparison with the cross section the ring grooves 7, 8 are formed.

Es hat sich gezeigt, daß ein besonders guter Halt und ein einfaches Abziehen der Kappe 9 möglich ist, wenn die äußere Ringnut 7 schmäler ist als die innere Ringnut 8, wie dies- das Ausführungsbeispiel deutlich zeigt.It has been shown that a particularly good hold and a simple removal of the cap 9 is possible if the outer annular groove 7 is narrower than the inner annular groove 8, as is clearly shown by the exemplary embodiment.

Vorzugsweise ist die Tiefe T der Ringnuten 7, 8 gleich oder wenigstens nahezu gleich.The depth T of the annular grooves 7, 8 is preferably the same or at least almost the same.

Der Querschnitt der Ringnuten 7, 8, ist vorzugsweiserechteckig oder trapezförmig, annähernd trapezförmig oder halbellipsenförmig in Bezug auf die Längsachse in Zapfenrichtung gesehen. Auch kann eine Kombination dieser Ausgestaltung vorteilhaft sein, wie die Ausführungsbeispiele anhand der Figuren 4a und 4b veranschaulichen. Dort ist der äußere Querschnittsabschnitt 16 als Rechteck ausgebildet, so daß etwa senkrecht zur Zapfenlängsrichtung verlaufende Halte- und Anschlagkanten 17, 18 gebildet sind. Der innere Querschnittsabschnitt 19 ist trapezförmig ausgebildet und erleichtert zusammen mit den halbkreisförmig oder gegengleich ausgebildeten Ringrippen 14, 15 der Kappe 9 bzw. des Kappenteils 9a ein leichteres Einsetzen und Abziehen derselben.The cross section of the ring grooves 7, 8 is preferably rectangular or trapezoidal, approximately trapezoidal or semi-elliptical in relation to the longitudinal axis in the journal direction. A combination of this configuration can also be advantageous, as the exemplary embodiments illustrate with reference to FIGS. 4a and 4b. There, the outer cross-sectional section 16 is formed as a rectangle, so that holding and stop edges 17, 18 which are approximately perpendicular to the longitudinal direction of the pin are formed. The inner cross-sectional section 19 is trapezoidal and, together with the semicircular or oppositely shaped ring ribs 14, 15 of the cap 9 or the cap part 9a, facilitates easier insertion and removal thereof.

Günstigerweise sind bei trapezförmiger Ausgestaltung die Nutwände 20, 21 der äußeren, schmäleren Ringnut 7 steiler als diejenigen 22, 23 der Ringnut 8, so daß die Ringnut 7 eine größere Trapezhöhe besitzt als die Ringnut 8.In the case of a trapezoidal configuration, the groove walls 20, 21 of the outer, narrower annular groove 7 are advantageously steeper than those 22, 23 of the annular groove 8, so that the annular groove 7 has a greater trapezoidal height than the annular groove 8.

Insbesondere sind die äußeren Nutenwände 20, 22 gegenüber der Zapfenlängsachse steiler, schließen also einen kleineren Winkel ein als die inneren Nutenwände 21, 23. Hierdurch kann beispielsweise die Belastbarkeit der Kappen 9, 9a und deren Abziehbarkeit erleichtert werden. Der Winkel der Nutenwand 20 beträgt vorzugsweise zwischen 30° und 40°, insbesondere 35°, derjenige der Nutenwand 21 zwischen 40° und 50°, insbesondere 45°, derjenige der Nutenwand 22 zwischen 10° und 20°, insbesondere 13° und derjenige der Nutenwand 23 zwischen 30° und 40°, insbesondere 33°.In particular, the outer groove walls 20, 22 are steeper with respect to the longitudinal axis of the pin, that is, they enclose a smaller angle than the inner groove walls 21, 23. This can, for example, facilitate the resilience of the caps 9, 9a and their ability to be removed. The angle of the groove wall 20 is preferably between 30 ° and 40 °, in particular 35 °, that of the groove wall 21 between 40 ° and 50 °, in particular 45 °, that of the groove wall 22 between 10 ° and 20 °, in particular 13 ° and that Groove wall 23 between 30 ° and 40 °, in particular 33 °.

Als Material für den Zapfen 2 wird relativ hartes oder sehr hartes und möglichst auch biegefestes Material verwendet. Bei angeformten Zapfen 2 besteht daher die Schuhsohle 1 oder wenigstens deren laufsohlenseitiger Teil aus derart hartem Material, wie beispielsweise aus Hart-PVC, Hart-Polyurethan, Polyäthylen, Polyamid, Polyimid oder Polykarbonat. Bei Verwendung von Zapfen 2 als in die Sohle 1 eingeformte Einzelelemente bestehen diese aus den genannten Kunststoffen, wobei die Sohle 1 in diesem Falle aus dem gleichen oder aus einem weicheren Material bestehen kann.Relatively hard or very hard and, if possible, also flex-resistant material is used as the material for the pin 2. When the spigot 2 is molded on, the shoe sole 1 or at least its outsole-side part is made of such a hard material, such as hard PVC, hard polyurethane, polyethylene, polyamide, polyimide or polycarbonate. When using pegs 2 as individual elements molded into the sole 1 elements consist of the plastics mentioned, the sole 1 in this case being made of the same or a softer material.

Die Zapfen 2 können als Einzelelemente auch aus Metall, wie beispielsweise aus Aluminium, Kupfer, Messing, Bronce, Stahl, Zinkdruckguß oder dgl. oder aus Keramik, wie beispielsweise aus Aluminiumoxid, Zirkondioxid, Steatit, Siliziumkarbid, Korund oder dgl. oder aus Mischungen derselben oder mit anderen keramischen Versätzen, wie Si02, CaO, Mg0 etc. bestehen.The pins 2 can also be made of metal, such as aluminum, copper, brass, bronze, steel, die-cast zinc or the like, or ceramic, such as aluminum oxide, zirconium dioxide, steatite, silicon carbide, corundum or the like, or mixtures thereof or with other ceramic offsets, such as Si0 2 , CaO, Mg0 etc. exist.

Auch kann anstelle einer Platte 12, die auf die Kappe 9 oder den Kappenteil 9a aufgebracht wird, oder zusätzlich hierzu, die Kappe 9 oder der Kappenteil 9a ganz oder jedenfalls an der Tritt-oder Greifzone mit hochabriebfestem Material versetzt sein, beispielsweise mit Glas- und/oder Metallfasern, Metallpulver oder Metalloxidpulver oder -teilchen. Dies kann durch, Eindrücken des abriebfesten Materials geschehen oder durch Verspritzen eines mit diesem Material gemischten Kunststoffes.Instead of a plate 12, which is applied to the cap 9 or the cap part 9a, or in addition to this, the cap 9 or the cap part 9a can be completely or at least mixed with highly abrasion-resistant material at the treading or gripping zone, for example glass and / or metal fibers, metal powder or metal oxide powder or particles. This can be done by pressing in the abrasion-resistant material or by injecting a plastic mixed with this material.

Um die Kappe 9 leicht montieren und demontieren zu können, sind an der Kappe 9 oder an dem Kappenteil 9a Steckansätze 24 in Form von Erhöhungen und/oder Vertiefungen vorgesehen, an denen ein Einsetz- oder Abziehwerkzeug angreifen kann. Im Ausführungsbeispiel sind diese am Außenmantel der Kappe 9 bzw. des Kappenteils 9a als prismenartige Ausschnitte ausgebildet und gemäß Figur 9 ist dieser Steckansatz 24 als Ringsicke ausgebildet. Es sind natürlich auch andere Formen der Steckansätze 24 möglich, beispielsweise in Gewindeform oder als Außensechskant oder -mehrkant oder dgl.In order to be able to easily assemble and disassemble the cap 9, plug-in projections 24 in the form of elevations and / or depressions are provided on the cap 9 or on the cap part 9a, on which an insertion or removal tool can engage. In the exemplary embodiment, these are formed on the outer jacket of the cap 9 or the cap part 9a as prism-like cutouts and, according to FIG. 9, this plug-in projection 24 is designed as a ring bead. Of course, other shapes of the plug-in projections 24 are also possible, for example in the form of threads or as an external hexagon or polygon or the like.

Zur Erhöhung der Trittbelastbarkeit und seitlichen Versteifung sind zwischen den Zapfen 2 und der Schuhsohle 1 eine oder mehrere Vertiefungen 25 in der Schuhsohle 1 vorgesehen (Figur 2), beispielsweise in Form einer oder mehrerer konzentrischer, umlaufender oder unterbrochener Nutenringe. Diese werden jedoch vorzugsweise durch eine Materialverdickung der Schuhsohle 1 gebildet, so daß die Sohlendicke dadurch nicht verringert wird. Die Kappe 9 bzw. der Kappenteil 9a besitzen entsprechende, in die Vertiefungen 25 eingreifende Vorsprünge 26, beispielsweise in Form von Rippen, insbesondere in Kreisform bzw. in unterbrochener Kreisform. Zusätzlich können die Kappen 9 bzw. die Kappenteile 9a jeweils eine Anschlagkante 27 aufweisen, die auf der Schuhsohle 1 oder an der die Vertiefung 25 bildenden, insbesondere ringförmigen Erhöhung 28 anliegt.To increase the load-bearing capacity and lateral stiffening, one or more depressions 25 are provided in the shoe sole 1 between the pin 2 and the shoe sole 1 (FIG. 2), for example in the form of one or more concentric, circumferential or interrupted groove rings. However, these are preferably formed by a material thickening of the shoe sole 1, so that the sole thickness is not reduced thereby. The cap 9 or the cap part 9a have corresponding projections 26 which engage in the depressions 25, for example in the form of ribs, in particular in a circular shape or in an interrupted circular shape. In addition, the caps 9 or the cap parts 9a can each have a stop edge 27 which bears on the shoe sole 1 or on the, in particular annular, elevation 28 forming the depression 25.

Es sei noch erwähnt, daß die Zapfen 2 und/oder die Kappen 9 oder die Kappenteile 9a und/oder die Platte 12 verschiedene Länge in Richtung der Zapfenachse aufweisen können, so daß die Griffigkeit des Sportschuhes - wie bekannt - den Gegebenheiten eines Spielfeldes angepaßt werden kann.It should also be mentioned that the pins 2 and / or the caps 9 or the cap parts 9a and / or the plate 12 can have different lengths in the direction of the pin axis, so that the grip of the sports shoe - as is known - can be adapted to the conditions of a playing field can.

Zur weiteren Verfestigung der Rastanordnung zwischen Zapfen 2 und Kappe 9, 9a können die Kappen 9, 9a in der Längsachse einen nach innen gerichteten Zapfen 29 aufweisen, der in eine entsprechende Öffnung 30 der Zapfen 2 (Figur 6) eingreift.To further solidify the locking arrangement between the pin 2 and the cap 9, 9a, the caps 9, 9a can have an inwardly directed pin 29 in the longitudinal axis, which engages in a corresponding opening 30 in the pin 2 (FIG. 6).
