Abstract

The invention is with respect to fixing studs in the shoe soles. A sport shoe, as an example of the invention has pockets in its sole, into each of which the wider base plate at the end of a stud may be slipped and then locked in position tightly by a keeper washer with outward lock parts on its edge locking into grooves in the walls of the pocket like a bayonet-joint. For stopping the stud turning in its pocket it may have a hollow in its base locking onto an unround horn or the like on the floor of the pocket.

Description

Die Erfindung betrifft einen Sportschuh mit einer mit Greifelementen versehenen Sohle mit jeweils einem in der Sohle eingebetteten kreisförmigen Aufnahmeraum für eingesenkte Teile des Greifelementes.The invention relates to a sports shoe with a sole provided with gripping elements, each with a circular receiving space embedded in the sole for recessed parts of the gripping element.

Eine solche Renkbefestigung eines Greifelementes ist aus der DE-A-2 543 268 bekannt. Dabei ist das Greifelement selbst an seinem hinteren Ende mit Renkvorsprüngen versehen und wird in einer in der Sohle eingebetteten und mit Renknuten versehenen gesonderten Sohlenbuchse gehalten. Das Greifelement hat einen Führungszylinder, der durch einen Führungsraum der Sohlenbuchse passend ragt. Führungszylinder und Renkvorsprünge sind hier an Stelle der üblichen Gewindebolzen von schraubbaren Greifelementen getreten und das Gegengewinde der üblichen Sohlenbuchse durch den glatten Führungsraum und die endseitigen Renknuten ersetzt. Um die großen auf das Greifelement und die Sohlenbuchse wirkenden Biegemomente (Kippmomente) beherrschen zu können, müssen Sohlenbuchse und die besagten Teile des Greifelementes aus entsprechend festem Metall sein, was das Gewicht der Sportschuhe vergrößert. Außerdem müssen die aus der Sohle ragenden Teile des Greifelementes mit dem Führungszylinder fest verbunden sein und daher bei Abnutzung dieser Teile das gesamte Greifelement ausgewechselt werden. Die Verdrehungssicherheit solcher Greifelemente ist außerdem relativ klein, so daß die äußere Form des Greifelementes auf Körperformen mit verhältnismäßig kleinen Durchmessern und glatter Oberfläche beschränkt ist, insbesondere auf Greifelemente in Form von Spikes oder dergleichen.Such a bayonet attachment of a gripping element is known from DE-A-2 543 268. In this case, the gripping element itself is provided with bayonet projections at its rear end and is held in a separate sole bushing embedded in the sole and provided with bayonet grooves. The gripping element has a guide cylinder which protrudes through a guide space of the sole bushing. The guide cylinder and bayonet protrusions have replaced the usual threaded bolts with screwable gripping elements and the mating thread of the usual sole bushing has been replaced by the smooth guide space and the bayonet grooves on the end. In order to be able to master the large bending moments (tilting moments) acting on the gripping element and the sole bushing, the sole bushing and the parts of the gripping element in question must be made of correspondingly strong metal, which increases the weight of the sports shoes. In addition, the parts of the gripping element protruding from the sole must be firmly connected to the guide cylinder, and the entire gripping element must therefore be replaced when these parts wear out. The security against rotation of such gripping elements is also relatively small, so that the outer shape of the gripping element is limited to body shapes with relatively small diameters and a smooth surface, in particular to gripping elements in the form of spikes or the like.

Der Erfindung liegt die Aufgabe zugrunde, eine Renkbefestigung eines Greifelementes zu schaffen, bei der auf gesonderte Sohlenbuchsen sowie an dem Greifelement selbst befestigte Renkvorsprünge verzichtet werden kann und die Greifelemente in ihren aus der Sohle vorstehenden Teilen keiner Beschränkung hinsichtlich Größe und Form unterworfen sind und die Greifelemente auch mehrteilig sein können, so daß die der Abnutzung unterliegenden Teile einfach ausgewechselt werden können.The invention has for its object to provide a bayonet attachment of a gripping element, in which there is no need for separate sole bushings as well as bayonet projections attached to the gripping element itself and the gripping elements in their parts protruding from the sole are not subject to any size or shape restrictions and the gripping elements can also be in several parts, so that the parts subject to wear can be easily replaced.

Die Lösung der Aufgabe gelingt durch die Maßnahmen nach dem Kennzeichen des Patentanspruchs 1.The task is solved by the measures according to the characterizing part of patent claim 1.

Aus der US-A-3 066 425 ist zwar bereits eine Befestigung eines Greifelementes in der Sohle eines Sportschuhes mit jeweils einem in der Sohle eingebetteten kreisförmigen Aufnahmeraum für eingesenkte Teile des Greifelementes bekannt, bei dem derAufnahmeraum in der Sohle als Hohlraum mit einer hinterschnittenen Ringnut ausgebildet ist, wobei der eingesenkte Teil des Greifelementes tellerartig ausgebildet ist und durch einen in die davor liegende Ringnut eingesetzten Seegerring gehalten ist. Zur Montage und Demontage wird der Seegerring in der an sich bekannten Weise mittels einer entsprechenden Zange in seinem Radius verkleinert und kann so aus der Ringnut entnommen oder in diese eingesetzt werden, wo er den eingesenkten Fußteil des Greifelementes übergreift und formschlüssig lagesichert. Der Seegerring kann eine wellige Form aufweisen und so unter Vorspannung an dem eingesenkten Fußteil des Greifelementes anliegen..From US-A-3 066 425 a fastening of a gripping element in the sole of a sports shoe is already known, each with a circular receiving space embedded in the sole for recessed parts of the gripping element, in which the receiving space in the sole is designed as a cavity with an undercut annular groove is, the recessed part of the gripping element is plate-shaped and is held by a circlip inserted in the annular groove in front of it. For assembly and disassembly, the circlip is reduced in radius in the manner known per se by means of a pair of pliers and can thus be removed from the ring groove or inserted into it, where it engages over the recessed foot part of the gripping element and locks it in a form-fitting manner. The circlip can have a wavy shape and thus bear against the recessed foot part of the gripping element under prestress.

Hierbei ist jedoch nachteilig, daß auch eine Montage des Greifelementes lediglich mit einem entsprechenden zangenförmigen Werkzeug möglich ist, um den Seegerring einsetzen zu können. Sofern der Seegerring mit merklicher Vorspannung am eingesenkten Fußteil des Greifelementes anliegen soll, ist sein Einsetzen in die Ringnut sehr aufwendig und umständlich sowie gegebenenfalls nur mittels weiteren Spezialwerkzeugs möglich, da das Einsetzen in die Ringnut eine entsprechende Verformung unter Aufbringung der vom Seegerring gewünschten Vorspannkraft erfordert. Weiterhin liegt der Seegerring, wenn er mit beherrschbaren Kräften radial komprimierbar sein soll, mit nur relativ geringer Anlagefläche an dem eingesenkten Fußteil des Greifelementes an. Wenn hierdurch verhindert werden soll, daß der Fußteil des Greifelementes durch Verformung freikommt, muß der Fußteil aus Metall bestehen, was entsprechende Gewichtserhöhungen mit sich bringt. Eine Verwendung von Stollen bzw. Fußteilen aus weichem Material wie Gummi oder Kunststoff etwa Polyurethan, scheidet bei einer derartigen Befestigung aus, ist jedoch erfindungsgemäß infolge der vollflächigeren Anlage ohne weiteres möglich, ebenso wie eine Verwendung eines Renkringes aus Kunststoff zur weiteren Gewichtsersparnis und Verbilligung. Schließlich ist der Aufnahmeraum des Sportschuhes gemäß der US-A-3 066 425 nach unten im Innenraum des Seegerrings offen und so Verschmutzungen ausgesetzt, was insbesondere die Demontierbarkeit des Greifelementes erheblich erschweren kann.However, it is disadvantageous here that the gripping element can only be assembled using a corresponding pliers-shaped tool in order to be able to use the circlip. If the circlip is to bear a noticeable pre-tension on the recessed foot part of the gripping element, its insertion into the annular groove is very complex and cumbersome and possibly only possible by means of further special tools, since the insertion into the annular groove requires a corresponding deformation while applying the pre-tensioning force desired by the circlip. Furthermore, the circlip, if it is to be radially compressible with manageable forces, lies against the recessed foot part of the gripping element with only a relatively small contact surface. If this is to prevent the foot part of the gripping element from being released by deformation, the foot part must be made of metal, which entails corresponding weight increases. The use of studs or foot parts made of soft material such as rubber or plastic, such as polyurethane, is ruled out in the case of such a fastening, but is readily possible according to the invention as a result of the full-surface contact, as is the use of a plastic ring for further weight savings and cost reduction. Finally, the receiving space of the sports shoe according to US-A-3 066 425 is open at the bottom in the interior of the circlip and is thus exposed to dirt, which in particular can make the removal of the gripping element considerably more difficult.

Jeder Aufnahmeraum hat in gleichen Abständen verteilt angeordnete hinterschnittene Renknuten 2C über der Bodenfläche 2A, die überdeckte Außenwände 2E haben, welche seitlich mit Stecköffnungen 4 für starre Renkvorsprünge 3B eines gesonderten Renkringes 3, im Beispielsfalle aus Metall, stufenlos verbunden sind. Innerhalb der Innenwand 2F des Aufnahmeraumes 2 ist die kreisförmige Grundplatte 1A des Greifelementes 1 verdrehungssicher gelagert, wozu ein zentraler, unrunder Vorsprung 2B der Bodenfläche 2A des Aufnahmeraumes 2 passend in eine entsprechend unrunde unterseitige Ausnehmung 1B in der Grundplatte 1A ragt, wenn das Greifelement 1 von oben in den Aufnahmeraum 2 eingesenkt wird. Aus der Grundplatte 1A ragt oberseitig zentrisch der zylinder- oder kegelstumpfförmige Zentrierteil 1C des Greifelementes 1 hervor, der von dem Renkring 3 umgeben ist. Der Renkring liegt mit seinem nach unten offenen Querschnitt auf der freien Ringfläche der Grundplatte 1A auf. Dabei ragen seine an der Außenkante segmentartigen, radial nach außen abgewinkelten starren Renkvorsprünge 3B in die Renknuten 2C, wenn der Renkring mit seinen Renkvorsprüngen vorher von oben in die Stecköffnungen 4 eingesteckt und dann auf der Ringfläche aufliegend in die Renknuten eingedreht ist. Die Unterseite des Renkringes, die Deckfläche der Renknuten und/ oder die Oberseite der Renkvorsprünge sowie gegebenenfalls die freie Ringfläche des Greifelementes können verdrehungshindernd ausgestaltet sein, damit der an sich im Gebrauch kaum von Verdrehungsmomenten belastete Renkring durch elastische Vorspannung in kraftschlüssigem und formschlüssigem Kontakt mit anderen Teilen der Renkbefestigung und des Greifelementes gehalten wird. Zum Niederdrücken und Verdrehen des Renkringes weist dieser an der Oberseite 3A Eingriffstellen 3E für einen Drehschlüssel auf, die auf einfache Weise als Stecköffnungen ausgebildet sind.

  • Fig. A longitudinal section along the line VIII- VIII in Fig. 9 by a receiving space in the sole for gripping elements including ring rings according to Fig. 5 or 6,
  • Fig. 9 is a plan view of the article of Fig. 8 and
  • Fig. 10 is a longitudinal section of a two-layer gripping element according to the invention. According to FIGS. 1 and 2, the attachment of interchangeable fastening element-free gripping elements 1 is provided in a plastic sole 5 of a sports shoe at several points, for which purpose cavities formed in the sole are designed as annular receiving spaces 2. Each receiving space has undercut steering grooves 2C arranged at equal intervals above the floor surface 2A, which have covered outer walls 2E, which are connected laterally with plug-in openings 4 for rigid steering projections 3B of a separate steering ring 3, in the example made of metal. Within the inner wall 2F of the receiving space 2, the circular base plate 1A of the gripping element 1 is mounted to prevent rotation, for which purpose a central, non-circular projection 2B of the bottom surface 2A of the receiving space 2 fits into a correspondingly non-circular underside recess 1B in the base plate 1A when the gripping element 1 of is sunk into the receiving space 2 at the top. The cylindrical or frustoconical centering part 1C of the gripping element 1, which is surrounded by the ring ring 3, projects centrally from the base plate 1A. The ring ring lies with its cross section open at the bottom on the free ring surface of the base plate 1A. In this case, its rigid segmental projections 3B on the outer edge, which are angled radially outward, project into the segmental grooves 2C when the segmental ring with its segmental projections is previously inserted into the plug-in openings 4 from above and then screwed into the segmental grooves lying on the ring surface. The underside of the bayonet ring, the top surface of the bayonet grooves and / or the top of the bayonet protrusions and, if applicable, the free ring area of the gripping element can be designed to prevent rotation, so that the bayonet ring itself, which is hardly loaded by torsional moments in use, is elastically preloaded in positive and positive contact with other parts the bayonet attachment and the gripping element is held. To depress and twist the steering ring, this has on the top 3A engagement points 3E for a rotary key, which are designed in a simple manner as plug-in openings.

Damit der eingedrehte Renkring 3 bei Auswechseln eines Greifelementes 1 leicht ausgedreht werden kann, ist es vorteilhaft, die Stecköffnungen 4 bei eingedrehtem Renkring 3 gegen das Eindringen von Fremdkörpern abzudecken, wozu gemäß Fig. 3 und 4 der Renkring 3 aus Metall in Umfangsrichtung zwischen den Renkvorsprüngen an seiner Oberseite 3A ebenfalls radial nach außen vorragende starre Abdeckvorsprünge 3D aufweist, d. h. Renkvorsprünge und Abdeckvorsprünge sind in Umfangsrichtung gesehen jeweils freibleibend versetzt, wobei die Abdeckvorsprünge aus aufgebogenen Seitenwandteilen gebildet sein können.So that the screwed-in ring 3 can be easily turned out when a gripping element 1 is replaced, it is advantageous to cover the plug-in openings 4 when the ring 3 is screwed in against the ingress of foreign bodies, for which purpose, according to FIGS. 3 and 4, the metal ring 3 in the circumferential direction between the ring projections at its top 3A also has radially outwardly projecting rigid cover projections 3D, d. H. Renk projections and cover projections are each subject to change in the circumferential direction, the cover projections can be formed from bent side wall parts.

Statt eines metallischen Renkringes mit starren Renkvorsprüngen und gegebenenfalls vorhandenen starren Abdeckvorsprüngen kann für die gleichen Aufnahmeräume und Greifelemente ein leichterer vollwandiger Renkring aus Kunststoff vorgesehen werden, wenn die Renkvorsprünge als in Längsrichtung des Greifelementes sich erstreckende, radial vorspringende starre Rastnasen ausgebildet sind. Die Abdeckung der Stecköffnungen des Aufnahmeraumes ist (nicht dargestellt) durch einen an der Oberseite des Renkringes nachgiebig angeformten, radial vorragenden Schirm möglich.Instead of a metallic bayonet ring with rigid bayonet projections and, if applicable, rigid cover projections, a lighter, full-walled bayonet ring made of plastic can be provided for the same receiving spaces and gripping elements if the bayonet projections are designed as radially projecting rigid locking lugs extending in the longitudinal direction of the gripping element. The plug-in openings of the receiving space can be covered (not shown) by a radially protruding screen which is resiliently molded onto the top of the ring ring.

Stecköffnungen und damit auch Abdeckvorsprünge oder Schirme sind bei Verwendung von Renkringen mit federnd nachgiebigen Rastnasen als Renkvorsprünge entbehrlich, wenn die Renkvorsprünge bis zum Umfang des Renkringes eindrückbar sind. Gemäß den Fig. 5, 6 und 7 sind die als angeformte Rastnasen ausgebildeten Renkvorsprünge 3C federnd soweit nach innen beim Aufsetzen auf die kreisförmige Öffnung des Aufnahmeraumes 2 gemäß Fig. 8 und 9 eindrückbar, daß sie nicht mehr über die Renkringkontur vorstehen und der Renkring 3 in den Aufnahmeraum bis zum Eingriff mit dem vorher eingesetzten Greifelement gegen Vorspannung eingedrückt werden kann. Sofern die Renkvorsprünge 3C nicht über den Renknuten 2C liegend dabei unmittelbar in diese einrasten, sondern sich über der Innenwand 2F befunden haben, ist der Renkring gegen Vorspannung durch einen mit den Eingriffstellen 3E lösbar gekuppelten Drehschlüssel nach dem Eindrücken in den Aufnahmeraum soweit zu verdrehen, bis die Renkvorsprünge gänzlich in die Renknuten eingedreht worden sind und sich radial entspannen können, so daß die unter Vorspannung bleibende Renkverbindung hergestellt ist.Plug-in openings and thus also cover projections or umbrellas are unnecessary when using ring rings with resilient locking lugs as bayonet projections if the bayonet projections can be pressed in up to the circumference of the ring. According to FIGS. 5, 6 and 7, the bayonet projections 3C, which are designed as molded-on latching lugs, are resiliently pressed inwards as far as they are placed on the circular opening of the receiving space 2 as shown in FIGS can be pressed against bias until it engages with the gripping element previously inserted. Insofar as the bayonet projections 3C do not snap directly into the baying grooves 2C, but have been located above the inner wall 2F, the bayonet ring can be turned against bias by a spanner that is detachably coupled to the engagement points 3E after being pressed into the receiving space until the bayonet projections have been completely screwed into the bayonet grooves and can relax radially, so that the bayonet connection which remains under tension is established.

Zum Ausrenken des Renkringes 3 ist dieAu- ßenwand 2E jeder Renknut 2C über eine Übergangswand 2D kontinuierlich mit der Innenwand 2F verbunden, so daß bei Verdrehen des Renkringes 3 in der entsprechenden Drehrichtung die federnden Renkvorsprünge 3C auf die Innenwand und damit außer Eingriff mit den Renknuten gebracht werden und durch Herausziehen des Greifelementes auch der Renkring aus dem Aufnahmeraum und damit von der Sohle entfernt wird.To disengage the steering ring 3, the outer wall 2E of each steering groove 2C is continuously connected to the inner wall 2F via a transition wall 2D, so that when the steering ring 3 is rotated in the corresponding direction of rotation, the resilient steering projections 3C are brought onto the inner wall and thus out of engagement with the steering grooves are and by pulling out the gripping element the ring is removed from the receiving space and thus from the sole.

Zum leichteren Eindrücken und Entfernen des Renkringes sind die federnden Rastnasen in Umfangsrichtung unterteilt.The resilient locking lugs are divided in the circumferential direction to make it easier to push in and remove the ring.

Da zwischen dem Umfang des Renkringes 3 mit den federnden Renkvorsprüngen und der kreisförmigen Eintrittsöffnung des Aufnahmeraumes 2 nur ein enger Ringspalt verbleibt, ist eine Verstopfung der Stellwege des Renkringes durch Schmutzteile praktisch ausgeschlossen und daher eine Abdeckung entbehrlich. Eine solche ist aber wiederum durch einen nicht dargestellten oberseitigen Schirm der vorher genannten Art leicht möglich.Since only a narrow annular gap remains between the circumference of the ring ring 3 with the resilient ring projections and the circular inlet opening of the receiving space 2, clogging of the travel paths of the ring ring by dirt parts is practically excluded and therefore a cover is unnecessary. However, such is not shown by one placed top screen of the aforementioned type easily possible.

Der Renkring mit federnden Renkvorsprüngen 3C nach Fig. 7 kann unterschiedlich gestaltete Längsschnitte haben, wie die Fig. 5 und 6 zeigen.The steering ring with resilient steering projections 3C according to FIG. 7 can have differently shaped longitudinal sections, as shown in FIGS. 5 and 6.

Bei gleicher Kontur nach Fig. 7 kann der Renkring 3 bei dickeren Sohlen 5 so ausgebildet sein, daß seine Unterseite entsprechend Fig. 5 auf der Ringfläche der Grundplatte 1A des gestrichelt dargestellten Greifelementes 1 unter Vorspannung gehalten abgestützt ist und seine Innenwand in ihrer Form am Zentrierteil 1 C des Greifelementes 1 eng anliegt.With the same contour according to FIG. 7, the ring 3 in thicker soles 5 can be designed such that its underside is supported under tension on the ring surface of the base plate 1A of the gripping element 1 shown in dashed lines as shown in FIG 1 C of the gripping element 1 is tight.

Bei dünneren Sohlen kann es dagegen vorteilhafter sein, den Renkring gemäß Fig. 6 mit seinem starren Mittelring 3F seitlich über die Grundplatte 1A bis fast zur Bodenfläche 2A des Aufnahmeraumes 2 ragen zu lassen und die Abstützung durch einen niedrigeren, unter Vorspannung gehaltenen, federnd angeformten konzentrischen Innenring 3G auf der Ringfläche der Grundplatte 1A vorzusehen, was insbesondere bei kleineren Greifelementen zweckmäßig ist. Der Innenring 3G kann in Umfangsrichtung durch radiale Einschnitte eine verbesserte Federwirkung erhalten.In the case of thinner soles, on the other hand, it can be more advantageous to have the ring ring according to FIG. 6 with its rigid central ring 3F protrude laterally over the base plate 1A almost to the bottom surface 2A of the receiving space 2 and the support by a lower, pre-tensioned, resiliently molded concentric To provide inner ring 3G on the ring surface of the base plate 1A, which is particularly useful for smaller gripping elements. The inner ring 3G can receive an improved spring action in the circumferential direction by radial incisions.

Der zentrale Vorsprung im Aufnahmeraum 2 kann außer zur Verhinderung des Verdrehens des Greifelementes auch zu dessen Abstützung für den herausragenden Teil mitbenutzt sein, wobei der Vorsprung als Stützteil entsprechend lang und steif ausgebildet ist und eventuell an die äußere Form des Greifelementes 1 angepaßt ist.The central projection in the receiving space 2 can be used in addition to preventing the twisting of the gripping element to support it for the protruding part, the projection being designed as a supporting part correspondingly long and stiff and possibly being adapted to the outer shape of the gripping element 1.

Um trotz einfacher Herstellung der Aufnahmeräume 2 in der Sohle 6 die Festigkeit der hinterschnittenen Teile zu erhöhen, können die Renknuten 2C nach außen durch einen Deckring 6 aus Metall (Fig. 8, 9) abgedeckt werden, der in die Sohle eingebettet und/öder sonstwie mit dieser in bekannter Weise fest verbunden ist.In order to increase the strength of the undercut parts despite simple manufacture of the receiving spaces 2 in the sole 6, the oval grooves 2C can be covered to the outside by a cover ring 6 made of metal (FIGS. 8, 9), which is embedded in the sole and / or otherwise is firmly connected to this in a known manner.

Bei der erfindungsgemäßen Ausführung der Renkbefestigung von Greifelementen ist in den Greifelementen selbst kein Befestigungsmittel mehr erforderlich, so daß die überstehenden Teile der Greifelemente jede gewünschte Form und/oder Größe erhalten können und u. U. gemäß Fig. 10 auch zweischichtig so gestaltet sein können, daß ein als Träger 1 D dienender fester Teil von einem auswechselbaren weicheren Mantel 1 E überdeckt und beide zusammen durch den Renkring 3 festgehalten werden. Es ist dabei unerheblich, ob die Greifelemente im vorstehenden Teil als Spikes, Stollen, Schneiden od. dgl. gestaltet sind.In the inventive design of the bayonet fastening of gripping elements, no fastening means is required in the gripping elements themselves, so that the protruding parts of the gripping elements can be given any desired shape and / or size and u. U. According to FIG. 10 can also be designed in two layers so that a solid part serving as a carrier 1 D is covered by an exchangeable softer jacket 1 E and both are held together by the ring ring 3. It is irrelevant whether the gripping elements in the above part are designed as spikes, studs, cutters or the like.
