It is not important that the ring body rests directly on the underside of the outsole, ie it lies in its plane.

Description

Die Erfindung betrifft einen Sportschuh, insbesondere Fußballschuh, mit den Merkmalen gemäß dem Oberbegriff des Anspruches 1.The invention relates to a sports shoe, in particular a soccer shoe, with the features according to the preamble of claim 1.

Aus der DE-OS 31 48 038 ist ein Sportschuh der vorstehend genannten Art bekannt, bei dem die Nocken jeweils aus einem mit der Laufsohle einstückigen Vorsprung, dem auf diesem Vorsprung aufgenommenen Ringkörper und einer ebenfalls von dem Vorsprung getragenen Nockenschale bestehen. Die Nockenschale ist durch eine Formschlußverbindung an dem Vorsprung befestigt und stützt sich über den druckelastischen Ring an der Unterseite der Laufsohle ab. Sie besteht aus einem im Vergleich zu dem Laufsohlenwerkstoff erheblichen verschleißfesteren Werkstoff und hat daher eine geringere elastische Nachgiebigkeit als dieser. Da jedoch der die Nockenschale und den Ringkörper aufnehmende Vorsprung einstückig mit der aus leichter verformbarem Werkstoff bestehenden Laufsohle ist, vermag dieser Vorsprung bei Druck- und Biegebelastungen nachzugeben, so daß insgesamt die so gestaltete Nocke elastisch ist. Hierdurch ist es möglich, bei Beibehaltung der für Nockensohlen typischen Nachgiebigkeit der Nocken die im Vergleich zu den Auftrittsflächen der Nocken geringer belastete Laufsohle aus einem billigeren und weicheren Werkstoff zu fertigen, ohne dadurch die Lebensdauer der Nockensohle zu verkürzen.From DE-OS 31 48 038 a sports shoe of the aforementioned type is known, 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. However, since 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.

Es ist auch bekannt, Laufsohlen für Sportschuhe mit daran einstückig angeformten Nocken insgesamt aus einem sehr verschleißfesten, jedoch dadurch teuren Werkstoff auszubilden, um dadurch den an den Nocken auftretenden Verschleiß zu verlangsamen und die Lebensdauer der Laufsohle zu verlängern. Aufgrund des abriebfesteren und härteren Werkstoffes sind die Nocken jedoch verhältnismässig unnachgiebig, so daß die für Nockenschuhe an sich erwünschte stoßdämpfende Eigenschaft dadurch erheblich gemindert ist.It is also known to design outsoles for sports shoes with cams integrally molded thereon from a very wear-resistant, but therefore expensive material, thereby slow down wear on the cams and extend the life of the outsole. However, due to the more abrasion-resistant and harder material, the cams are relatively unyielding, so that the shock-absorbing property desired per se for cam shoes is considerably reduced as a result.

Schließlich ist es von Stollen, d.h. auswechselbaren Greifelementen, auch schon bekannt, zwischen einem beispielsweise aus Metall bestehenden Halteteil und dem die Auftrittsfläche aufweisenden Stützteil aus verschleißfestem Werkstoff einen elastischen Gummikörper vorzusehen, der mit dem Halteteil und mit dem Stützteil durch Anvulkanisieren verbunden ist (DE-OS 23 13 646). Eine solche Befestigungsart für den die Auftrittsfläche aufweisenden unteren Nockenteil mit dem nachgiebigen Ringkörper und der Laufsohle kommt jedoch für Nockenschuhe aus Kostengründen nicht in Betracht, weil für jede Nocke eine getrennte Herstellung des unteren Nockenkörpers und des elastischen Gummikörpers sowie dessen Verbindung miteinander und mit der Laufsohle erforderlich wäre. Darüber hinaus ist eine Verbindung durch Anvulkanisieren nicht für beliebige Paarungen von Sohlenwerkstoffen möglich.After all, it is from studs, i.e. interchangeable gripping elements, also known, to provide an elastic rubber body between a holding part, for example made of metal, and the supporting part made of wear-resistant material, which is connected to the holding part and to the supporting part by vulcanization (DE-OS 23 13 646). Such a type of attachment for the lower cam part with the resilient ring body and the outsole having the tread surface is not suitable for cam shoes for cost reasons, because for each cam a separate production of the lower cam body and the elastic rubber body and its connection with one another and with the outsole is required would. In addition, a connection by vulcanization is not possible for any pair of sole materials.

Der Erfindung liegt die Aufgabe zugrunde, einen Nocken-Sportschuh der vorstehend angegebenen Art zu schaffen, der auch bei Anwendung eines verschleißfesten und daher härteren Werkstoffes für die Laufsohle und die Nocken die für Nockenschuhe erwünschte dämpfende Nachgiebigkeit der Nocken aufweist.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.

Erfindungsgemäß wird dies erreicht durch die Ausgestaltung gemäß dem Kennzeichen des Anspruches 1.According to the invention, this is achieved by the configuration according to the characterizing part of claim 1.

Bei der bekannten Nockenausbildung, von der die Erfindung ausgeht, besteht die Laufsohle und damit auch der Nockenvorsprung, auf den die Nockenschale aufgenommen ist, aus einem elastisch druckverformbaren Werkstoff, der die Gewähr bietet, daß trotz der relativen Unnachgiebigkeit der Nockenschale die Nocke insgesamt stoßdämpfend wirkt. Bei der vorliegenden Erfindung hingegen bestehen die Laufsohle und der untere Teil des Nockenkörpers sowie der diesen mit der Laufsohle verbindende Schaft aus einem relativ verschleißfesten und demzufolge weniger druckverformbaren Werkstoff. Gleichwohl wird die gewünschte Nachgiebigkeit der Nocke insgesamt erzielt, weil der Verbindungsschaft im Vergleich mit den Querabmessungen der Nocke insgesamt verhältnismässig dünn ist und beispielsweise sein Durchmesser nur ein Viertel des Nockendurchmessers beträgt. Hierdurch wird erreicht, daß auch schon bei einer geringfügig exzentrischen Belastung an der Nocke, d.h. einer nicht in Achsrichtung des Verbindungsschaftes verlaufenden Kraft, der nachgiebige Ringkörper bei einer gleichzeitigen elastischen Verbiegung des Verbindungsschaftes einseitig zusammengedrückt wird. Da in den seltensten Fällen eine exakt mit der Achse des Verbindungsschaftes fluchtende Belastung auftritt, wird somit durch dieses Kippen der Nocke die erwünschte Nachgiebigkeit erzielt. Darüber hinaus erfährt der Verbindungsschaft auch bei einer zentrischen Belastung aufgrund seines geringen Querschnittes eine relativ hohe Zusammenpressung so daß auch in diesem Fall die erwünschte Nachgiebigkeit gegeben ist.In the known cam design from which the invention is based, 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. In the present invention, however, 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. This ensures that even with a slightly eccentric load on the cam, ie a force not running in the axial direction of the connecting shaft, the resilient ring body is compressed on one side with simultaneous elastic bending of the connecting shaft. Since, in the rarest of cases, there is a load that is exactly aligned with the axis of the connecting shaft, the desired flexibility is achieved by this tilting of the cam. In addition, the connecting shaft is subjected to a relatively high compression even in the case of a centric load due to its small cross section, so that the desired flexibility is also given in this case.

Erfindungsgemäß ist somit der elastisch nachgiebige Ringkörper formschlüssig an der Nocke fixiert, so daß es möglich ist, hierfür auch Materialien einzusetzen, die sich mit dem Material der Laufsohle nicht oder nur schlecht verbinden lassen. Jedoch ist es auch im Rahmen der Erfindung von Vorteil, für den Ringkörper und die Laufsohle Werkstoffe zu verwenden, die sich beim Gießvorgang miteinander verbinden. Dies ist z.B. der Fall bei Polyurethanen unterschiedlicher Konsistenz, nämlich in hart eingestellter verschleißfester Form, in der in der Hauptsache Biegeelastizität vorliegt, für die Laufsohle und den unteren Nockenteil, hingegen in elastomerer kompressibler Form für den Ringkörper.According to the invention, 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. However, it is also advantageous within the scope of the invention to use 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.

Der von der Erfindung beabsichtigte Effekt hängt naturgemäß von dem Verhältnis der Elastizitätsmodule des Ringkörper- bzw. Laufsohlenwerkstoffes ab. Jedoch wird selbst bei relativ hartem und in der Hauptsache biegeelastischem Sohlenwerkstoff eine hinreichende Nachgiebigkeit der Nocken erreicht, wenn der Innendurchmesser des Ringkörpers und damit der Durchmesser des Verbindungsschaftes nur etwa ein Viertel bis die Hälfte des Nockendurchmessers beträgt.The effect intended by the invention naturally depends on the ratio of the elasticity modules of the ring body or outsole material. However, even with a relatively hard and mainly flexurally elastic sole 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.

Der Herstellungsvorgang gestaltet sich relativ einfach:
Vor der Gießformung der Laufsohle werden die elastischen Ringkörper in die Formausnehmungen des Gießwerkzeuges eingelegt, die die Nocken formen. Beim anschließenden Gießvorgang tritt des fließfähige Kunststoffmaterial durch den Ringkörper hindurch in den unteren Teil der Formausnehmungen ein und bildet damit, einstückig mit der Laufsohle, die Nocke. Es kommt dabei nicht darauf an, daß der Ringkörper unmittelbar an der Unterseite der Laufsohle anliegt, d.h. in deren Ebene liegt. Denn da die Nachgiebigkeit der Nocke im wesentlichen durch den Ringkörper bestimmt ist, kann dieser auch näher an der Auftrittsseite der Nocke angeordnet sein. Dies stellt geringere Anforderungen an die Einhaltung eines genauen Außendurchmessers des Ringkörpers. In der in der Regel schwach konusförmigen Formausnehmung des Gießwerkzeuges nimmt der Ringkörper selbsttätig die seinem Außendurchmesser entsprechende Position ein.
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.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der beiliegenden Zeichnungen näher erläutert. In den Zeichnungen zeigen:

  • Fig. 1 eine Seitenansicht eines Fußballschuhes der mit erfindungsgemässen Nocken ausgestattet ist;
  • Fig. 2 einen Schnitt längs der Linie II-II in Fig. 1 in vergrösserter Darstellung, und
  • Fig. 3 einen zu Fig. 2 analogen Schnitt durch eine modifizierte Ausführungsform der Nocke.
An embodiment of the invention is explained below with reference to the accompanying drawings. The drawings show:
  • Figure 1 is a side view of a soccer shoe equipped with cams according to the invention.
  • Fig. 2 shows a section along the line II-II in Fig. 1 in an enlarged view, and
  • Fig. 3 shows a section similar to Fig. 2 through a modified embodiment of the cam.

Der in Fig. 1 dargestellte Sportschuh, z.B. ein Fußballschuh, besitzt einen Schaft 1 und eine damit verbundene Laufsohle 2 aus einem biegeelastischen Werkstoff, z.B. Polyamid oder Polyurethan, der eine relativ hohe Verschleißfestigkeit gegenüber Abrieb besitzt. An die Laufsohle 2 sind in einer Weise, die aus Fig. 2 deutlicher wird, Nocken 3 einstückig angeformt. Die Laufsohle 2 weist etwa 20 derartiger Nocken 3 auf.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.

Wie sich aus Fig. 2 ergibt, setzt sich eine Nocke 3, die eine leicht nach unten sich verjüngende konische Form hat, im wesentlichen aus einem unteren Nockenteil 4, einem diesen mit der Laufsohle verbindenden Schaft 5 und aus einem Ringkörper 6 zusammen. Der Ringkörper 6 besteht aus einem druckelastischen Elastomer, z. B. einem Polyurethan, und hat eine Höhe von etwa der Hälfte der Gesamthöhe der Nocke 3. Der Innendurchmesser des Ringkörpers 6 beträgt im gezeigten Ausführungsbeispiel etwa nur die Hälfte des Außendurchmessers, so daß dementsprechend der Durchmesser des Verbindungsschaftes 5 auch nur etwa der Hälfte der Querabmessung der Nocke 3 entspricht. Der Ringkörper 6 liegt mit seiner oberen Begrenzungsfläche nicht in der Ebene der Laufsohle 2, sondern etwas darunter, wie aus Fig. 2 hervorgeht. Dadurch ist ein etwas nach unten vorspringender Sockel 7 an der Laufsohle 2 gebildet, der mit einer runden Auskehlung in die Laufseite der Laufsohle 2 übergeht. Der Innenrand des Ringkörpers 6 ist kräftig gerundet (Fig. 2).As can be seen from FIG. 2, 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. With its upper boundary surface, 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. As a result, 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).

In dem gezeigten Ausführungsbeispiel ist der Verbindungsschaft 5 konzentrisch zu der einen geraden Kegelstumpf bildenden Nocke 3 angeordnet. Es ist aber auch eine etwas exzentrische Anordnung davon möglich, wodurch beim Auftritt eine einseitige Nachgiebigkeit der Nocke 3 gefördert wird.In the exemplary embodiment shown, the connecting shaft 5 is arranged concentrically with the cam 3 forming a straight truncated cone. However, 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.

Bei der Herstellung der Laufsohle 2 werden in die Formausnehmungen einer nicht gezeigten Gießform, die zur Formung der Nocken 3 bestimmt sind, die vorgefertigten Ringkörper 6 eingelegt und anschließend, nach dem Schließen des Werkzeuges, wird fließfähiges Kunststoffmaterial der Laufsohle 2 eingespritzt. Die Ringöffnung in dem Ringkörper 6 dient dabei als Durchflußkanal für das Kunststoffmaterial zur Bildung des Nockenunterteiles 4, der auf diese Weise aus dem verschleißfesten Werkstoff der Laufsohle 2 gebildet wird. Durch den Druck des Spritzgießvorganges wird dabei jeder Ringkörper etwas komprimiert, so daß eine enge Anlage der Ringkörperober- und -unterseite an den angrenzenden Flächen der Nocke 3 gewährleistet ist, auch wenn die Werkstoffe des Ringkörpers 6 und der Laufsohle 2 miteinander keine Haft- oder Schweißverbindung eingehen. Abweichend von der beschriebenen Herstellungsart ist es auch möglich, den Ringkörper jeweils an Ort und Stelle zu gießen. Hierfür sind in bekannter Weise verschiebbare Stempel des Gießwerkzeuges erforderlich.In the manufacture of the outsole 2, 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.

Die Ausführungsform gemäß Fig. 3 unterscheidet sich von der zuvor beschriebenen lediglich durch den Verlauf des Verbindungsschaftes und durch die entsprechend andere Form des Ringkörpers. Aus diesem Grund sind mit Ausnahme dieser beiden Teile in Fig. 3 die gleichen Bezugszeichen wie in Fig. 2 verwendet. Bei dieser Ausführungsform verläuft der Verbindungsschaft 5′ unter einem von 90° verschiedenen Winkel zu den ebenen, an der Ober- und Unterseite des Ringkörpers 6′ anliegenden Flächen des Sockels 7 bzw. des Nockenunterteils 4.The embodiment according to 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. In this embodiment, 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'.

Der Winkel beträgt in dem gezeigten Ausführungsbeispiel etwa 45°. Entsprechend geneigt liegt die Bohrung des Ringkörpers 6′ zu dessen Ober- und Unterseite. Durch diese Schräganordnung der Verbindungsschaftes 5′ wird erreicht, daß auch bei einer zu der Achse der als gerader Kegelstumpf ausgebildeten Nocke 3′ konzentrischen Belastung der Verbindungsschaft 5′ eine Verbiegung erfährt und daher aufgrund der Druckverformbarkeit des Ringkörpers 6′ eine Beweglichkeit des Nockenunterteils 4 gegenüber der Laufsohle 2 ermöglicht. Diese Ausführungsform eignet sich daher besonders für sehr verschleißfeste und praktisch ausschließlich biegeelastische, jedoch kaum druckverformbare Werkstoffe für die Laufsohle 2. Infolge der Schräganordnung des Verbindungsschaftes 5′ hat die Nocke 3′ eine stärkere Tendenz zum Ausweichen nach einer Seite hin. Um ein Ausweichen des Schuhes insgesamt zu vermeiden, ist es in diesem Fall zweckmässig, die Orientierung des Verbindungsschaftes 5′ an den Nocken 3′ der Laufsohle unterschiedlich zu wählen, so daß sich die seitlichen Ausweichbewegungen kompensieren.In the exemplary embodiment shown, 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.

In den gezeigten Ausführungsbeispielen ist der Ringkörper 6 als planparallele Scheibe dargestellt. Es ist jedoch möglich, davon abweichende Gestaltungen zu wählen, z.B. die Ober- und Unterseite als konkave Schalen- oder Kegelfläche auszubilden. Hierdurch ist die Hachgiebigkeit des Ringkörpers 6 bzw. 6′ im Außenbereich aufgrund der dort grösseren Dicke ausgeprägter.In the exemplary embodiments shown, 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.

Weiterhin ist es, insbesondere bei der Ausführungsform gemäß Fig. 3, prinzipiell möglich, anstelle eines einzigen Verbindungsschaftes 5 bzw. 5′ mehrere noch dünnere Verbindungsschäfte zu wählen. Im Fall der Ausführungsform gemäß Fig. 3 könnten zwei einander kreuzende, d.h. mit entgegengesetztem Winkel verlaufende Verbindungsschäfte 5′ angeordnet werden.Furthermore, in particular in the embodiment according to FIG. 3, it is possible in principle to select several even thinner connecting shafts instead of a single connecting shaft 5 or 5 '. In the case of the embodiment according to FIG. 3, two connecting shafts 5 'crossing one another, ie running at an opposite angle, could be arranged.

Je nach der gewünschten elastischen Nachgiebigkeit der Nocken sind auch Abweichungen bezüglich der Höhe bzw. Dicke des elastischen Ringkörpers möglich. Wenn beispielsweise eine geringere elastische Nachgiebigkeit der Nocken gewünscht ist, dann ist es zweckmässig, anstelle der in den Ausführungsbeispielen gewählten Dicke des Ringkörpers 6, die annähernd der Hälfte der Nockenhöhe entspricht, nur ein Drittel oder ein Viertel davon zu wählen. Weiterhin kann auch bei der Ausführungsform gemäß Fig. 3 von der dort gezeigten scharfkantigen Ausführung des Innenrandes des Ringkörpers 6′ insofern abgewichen werden als zur Vermeidung von Spannungskonzentrationen an den entsprechend scharfen Kanten des Nockenschaftes 5′ auch dort Rundungen ähnlich der Ausführungsform gemäß Fig. 2 vorgenommen werden. Bei der Ausführungsform gemäß Fig. 2 kann die Rundung im übrigen, insofern von der zeichnerischen Darstellung abweichend, sogar einem Kreisbogen mit einem der halben Höhe des Ringkörpers 6 entsprechenden Radius entsprechen.Depending on the desired elastic compliance of the cams, deviations in the height or thickness of the elastic ring body are also possible. If, for example, a lower elastic resilience of the cams is desired, then it is expedient to choose only a third or a quarter thereof instead of the thickness of the ring body 6 selected in the exemplary embodiments, which corresponds approximately to half the cam height. Furthermore, in the embodiment according to FIG. 3, there can also be deviations from the sharp-edged design of the inner edge of the ring body 6 'shown there, in order to avoid stress concentrations on the correspondingly sharp edges of the cam shaft 5', there also rounding similar to the embodiment according to FIG. 2 will. In the embodiment according to FIG. 2, 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.

In vielen Fällen ist es erwünscht, die Unterseite auch von Nockenschuhen mit Verstärkungsrippen zu versehen, die - zur Vermeidung einer übermässigen Sohlendicke an der Stelle dieser Rippen - durch in das Sohlenmaterial ganz oder mit ihrer Oberseite eingebettete Einlegeteile aus härterem Material gebildet sind. Solche Einlegeteile haben häufig auch rein geschmacklichen Charakter und werden zur Verbesserung des Erscheinungsbildes der Sohle in gefälliger Form und in der Farbe abweichend vom Sohlenmaterial ausgestaltet. Derartige Einlegeteile werden - ähnlich wie das für die elastischen Ringkörper geschildert ist - bei der Gießherstellung der Sohle zunächst in das Gießwerkzeug eingelegt und dann von dem Sohlenmaterial umgossen. Da in solchen Fällen, und bei Verstärkungsrippen sogar gezielt, die Nocken auf den Einlegeteilen zu sitzen kommen, versteht es sich, daß dann der in den Ausführungsbeispielen erkennbare Sockel 7 durch ein solches Einlegeteil gebildet ist und bei der Sohlenherstellung Ringkörper und Einlegeteil in der entsprechenden Lage im Gießwerkzeug angeordnet werden müssen.In many cases it is desirable to provide the underside of cam shoes with reinforcing ribs, which - in order to avoid excessive sole thickness at the location of these ribs - are formed from inserts made of harder material completely or with their upper side embedded in the sole material. Such inserts often have a purely taste character and are designed to improve the appearance of the sole in a pleasing form and in a color that differs from the sole material. Such inserts - similar to what is described for the elastic ring body - are first inserted into the casting tool during the production of the sole and then cast around the sole material. Since in such cases, and even specifically in the case of reinforcing ribs, the cams come to sit on the inserts, it goes without saying that then in the exemplary embodiments 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.
