Definitions
- the invention relates to an outsole made of resilient plastic for sports shoes with the features according to the preamble of claim 1.
- the invention is therefore based on the object of providing an outsole of the type mentioned at the outset, which makes it easier to adapt the damping ability of the outsole to different body weights of the runners without the runners having to intervene themselves.
- the outsole is intended to reduce the harmful peak load due to the catapult effect.
- the damping body consists of a large number of individual bodies which are only supported in regions or points against one another in an unloaded state and which can lie directly against one another or are connected to one another by interposed elastic material, results in a progressive spring behavior.
- the invention is based on the principle known in principle that progressive spring detection of the elastic damping body automatically adapts it to different body weights of the runners. Because at low loads, the existing soft suspension can provide sufficient travel, while the increase in travel increases with increasing load in accordance with the progressively increasing spring detection, so that a heavy runner sinks into the outsole relatively less. In this sense, a damping body consisting of a large number of small individual bodies proves to be a surprisingly simple solution for a progressive spring behavior.
- the individual bodies which are preferably spheres, but can also be cubes, cylinders, cuboids or other symmetrical or asymmetrical structures, support each other loaded condition, in which they normally completely fill the recess under the heel contact surface, due to their shape only point, line or area to each other. As a result, they create gaps in the damping body formed by their entirety. As a result of these only small-area contact with one another, the load exerted on them is divided into a corresponding number of individual forces, which initially result in locally high deformation of the individual bodies. However, with increasing deformation, the contact and support surface between the individual bodies increases, so that the flexibility is getting lower. It is only at the point in time when all of the intermediate spaces are consumed by the elastic deformation of the individual bodies, ie the individual bodies are “in block”, that the damping body behaves overall like a compact elastic body with approximately linear spring detection.
- the progressivity of the spring characteristic of the damping body according to the invention can be determined by choosing the size of the individual bodies.
- the limits of the main transverse dimension or the diameter of the individual bodies are expediently 2 and 12 mm. However, a size of 3 to 8 mm is preferred.
- the progressive spring detection of the damping body which can be achieved in a simple manner in this way is accompanied by a significant further advantage of this solution. Since the individual bodies can also move relative to one another in the recess when a load occurs, part of the impressed kinetic energy is converted into friction. This has the effect that when the damping body is relieved, it does not fully return the force acting on it to the runner's heel, but only to a somewhat lesser extent. This will the normally desired catapult effect, which accelerates the runner slightly upwards as the rolling phase continues, is reduced. However, it has been shown that a fully elastic behavior of the damping body, which fully returns the previously intercepted force to the heel when relieved, can result in health problems in the heel and Achilles tendon area.
- the individual bodies for example balls
- the individual bodies can be formed in one piece with a thin membrane, which fixes them at such a small distance from one another that there are at most tiny bridges between the individual bodies.
- a thin membrane which fixes them at such a small distance from one another that there are at most tiny bridges between the individual bodies.
- direct attachment of the spheres to one another is also possible in the case of fixation by means of a membrane, since the membrane can only be separated by the gaps which already exist due to the shape needs to stretch.
- the membrane should be kept very thin, for example with a thickness of only a few tenths of a millimeter.
- the desired binding of the individual bodies to one another can also be brought about by tiny rod-shaped or ring-shaped bridges, which can likewise be produced in one piece with the individual bodies, for example by injection molding.
- Both the membrane and this bridge-shaped matrix can be flat or spatial.
- a flat design, in which the individual bodies also lie in one plane, is expedient insofar as the damping body can be constructed as a whole by several layers of these individual bodies bound in this way.
- the outsole shown in the drawings consists of a midsole 1 made of elastic plastic, e.g. Polyurethane with a Shore A hardness of 25 to 65 (corresponding to Shore-C from 40 to 80), a wear sole 2 connected to it on the running side, for example made of rubber, which may have a profiling (not shown in more detail), and a heel bed shell 3, which with the foot side of the midsole 1 is connected in the heel area and may have a Shore hardness of the same order of magnitude as the midsole or slightly above it.
- a midsole 1 made of elastic plastic, e.g. Polyurethane with a Shore A hardness of 25 to 65 (corresponding to Shore-C from 40 to 80)
- a wear sole 2 connected to it on the running side, for example made of rubber, which may have a profiling (not shown in more detail)
- a heel bed shell 3 which with the foot side of the midsole 1 is connected in the heel area and may have a Shore hardness of the same order of magnitude as the midsole or slightly above it
- a recess 4 is formed in the midsole 1 below the heel contact area, that is to say the area indicated by A in FIG extends upwards.
- the recess 4 ends at a distance of only about 0 to 2 mm in front of the separating surface between the heel bed shell 3 and the midsole 1.
- the diameter of the recess 4 is approximately 3.5 to 4 cm in the exemplary embodiment shown; their height is about 12.5 to 13 mm.
- the recess 4 is provided with a plurality of small balls 5 made of an elastomeric material of high elasticity, e.g. Polyurethane or rubber, filled.
- the balls 5 have a largely smooth outer surface, so that they cannot get caught in one another when the load occurs, but only support one another under load or even have a certain relative mobility.
- the balls 5 can, without this being clear from the drawing, before they are combined into a damping body corresponding to the shape of the recess 4 with an adhesive or binder, e.g. sprayed with a silicone rubber solution to adhere to each other and during the outsole manufacturing process, i.e. can be used as a closed damping body in the recess 4 before the wear sole 2 is applied to the midsole 1.
- an adhesive or binder e.g. sprayed with a silicone rubber solution to adhere to each other and during the outsole manufacturing process, i.e. can be used as a closed damping body in the recess 4 before the wear sole 2 is applied to the midsole 1.
- the recess 4 is closed on its underside by the wear sole 2.
- an opening 6 can be provided in the area of the recess 4, which opening is closed by a transparent plate 7 - possibly made of a harder material than the wear sole 2.
- Fig. 3 shows a damping body, which consists of two spherical layers 51 and 52.
- Each of the two spherical layers 51, 52 is formed in that spheres 5 arranged in one plane are bound to one another by very small connecting webs 53 which are formed in one piece with the spheres, for example by injection are poured.
- the balls are held by this matrix of connecting webs 53 in such a way that each ball layer 52 is easy to handle.
- both spherical layers 51, 52 have an essentially circular outline of a size such that they fit into the correspondingly designed recess 4 and largely fill them (FIG. 1).
- the upper spherical layer 51 has a sphere in the center of the circle, while the center of the lower spherical layer 52 is not occupied. In this way, the balls of the two layers are "at a gap" to each other, since the ball size is the same, so that the truncated cone-shaped structure of the damping body shown in FIGS. 1 and 3 results.
- the shape of the recess 4 is adapted to this structure.
- the balls have a diameter of approximately 7 mm, which results in a total number of approximately 40 balls of the damping body.
- the shape of the recess in which the damping body is arranged can be arbitrary and have an oval or polygonal base area instead of a circular area.
- the friction existing between the individual bodies, here balls can be influenced in a targeted manner by deliberately keeping the surface rough or less rough. With greater roughness and thus increased friction, the balls absorb more energy and thereby reduce the force peak of the catapult effect to a greater extent. It is further understood that even when the balls are arranged in a matrix, the damping body is not limited to the design shown in FIG. 3.
Abstract
Description
Die Erfindung betrifft eine Laufsohle aus nachgiebigem Kunststoff für Sportschuhe mit den Merkmalen gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to an outsole made of resilient plastic for sports shoes with the features according to the preamble of claim 1.
Das Problem, die Laufsohle von Sportschuhen so auszubilden, daß sie die durch das Aufsetzen praktisch schlagartig auftretenden hohen Belastungen auf den Bewegungsapparat des Läufers ausreichend abfängt (dämpft) und zugleich das natürliche Laufverhalten nicht beeinträchtigt, ist Gegenstand zahlreicher Vorschläge und praktischer Ausgestaltungen. Die Hauptbelastung beim Aufsetzen erfolgt naturgemäß im Fersenbereich, da zumindest der Durchschnittsläufer dort den Fuß zuerst aufsetzt, so daß während einer kurzen Zeitspanne in der Abrollphase die Ferse und das Bein des Läufers durch eine grosse Kraft belastet sind. Die Größe dieser Kraft hängt wesentlich davon ab, über welchen "Federweg" der Laufsohle die in der Hauptsache durch das Körpergewicht und durch den Laufstil des Läufers bestimmte Bewegungsenergie bis zum Stillstand der Ferse relativ zur Bahnoberfläche aufgenommen wird. Seit jeher muß bei der Sohlenausgestaltung bezüglich dieses Federweges ein Kompromiß geschlossen werden, da ein an sich aus Gründen der geringeren Belastung erwünschter langer Federweg dem Läufer ein Schwimmgefühl vermittelt, welches die Laufleistung beeinträchtigt und auch wegen der Unsicherheit bei der Fußführung die Verletzungsgefahr fördert. Dieser Kompromiß hat auch auf die unterschiedlichen Körpergewichte der Läufer Rücksicht zu nehmen, da einleuchtenderweise eine für einen schweren Läufer einen ausreichenden Federweg und damit eine hinreichende Dämpfung vermittelnde Laufsohle für einen leichten Läufer zu hart ist, während die dem leichten Läufer angepasste Laufsohle durch die von einem schweren Läufer ausgeübten Sohlenbelastungen zu sehr zusammengedrückt wird und daher das erwähnte Schwimmgefühl erzeugt oder "durchschlägt". Es gibt daher zahlreiche Laufsohlen der eingangs genannten Art, die zur individuellen Anpassung der Dämpfungsfähigkeit der Laufsohle an die unterschiedlichen Körpergewichte der Läufer in Ausnehmungen unter der Fersenaufstandsfläche austauschbar eingesetzte Stützkörper oder dgl. aufweisen (vgl. DE-AS 29 04 540; DE-OS 32 45 964). Diese bekannten Lösungen setzen jedoch voraus, daß der Läufer selbst in der Lage ist, die für ihn notwendige Dämpfung zu bestimmen, d.h. die Auswahl der hierzu erforderlichen Dämpfungskörper selbst zu treffen, was jedoch keineswegs stets der Fall ist.The problem of designing the outsole of sports shoes in such a way that it adequately absorbs (dampens) the high loads on the musculoskeletal system of the runner, which occurs suddenly, and at the same time does not impair the natural running behavior, is the subject of numerous proposals and practical developments. The main load when touching down naturally takes place in the heel area, since at least the average runner puts the foot on there first, so that the heel and leg of the runner are loaded by a large force during a short period of time in the rolling phase. The magnitude of this force essentially depends on the "spring travel" of the outsole, the kinetic energy, which is mainly determined by the body weight and the running style of the runner, is absorbed relative to the track surface until the heel stops. A compromise has always been made in the design of the sole with regard to this spring travel, since a long travel which is desirable in itself because of the lower load gives the runner a feeling of swimming which affects the mileage and also promotes the risk of injury due to the uncertainty in the foot guidance. This compromise also takes into account the different body weights of the runners because, obviously, an outsole that provides sufficient travel for a heavy runner and thus sufficient cushioning is too hard for a light runner, while the outsole that is adapted to the light runner is compressed too much by the sole loads exerted by a heavy runner and therefore mentioned the above Creates or "punctures" swimming sensation. There are therefore numerous outsoles of the type mentioned at the outset which have interchangeably inserted support bodies or the like for the individual adaptation of the damping ability of the outsole to the different body weights of the runners in recesses under the heel contact surface (cf. DE-AS 29 04 540; DE-OS 32 45 964). However, these known solutions presuppose that the runner himself is able to determine the damping required for him, ie to make the selection of the damping bodies required for this himself, but this is by no means always the case.
Es ist weiterhin bekannt, daß die Federelastizität der Sohlenwerkstoffe der bekannten Laufsohlen einen sog. "Katapulteffekt" erzeugt, indem im Maße der örtlichen Belastungsverringerung während des Abrollvorganges die Sohle mit einer ihrer Zusammendrückung entsprechenden Kraft den Fuß nach oben beschleunigt. Obwohl dieser Katapulteffekt für die Laufleistung als fördernd angesehen wird, ist er in ausgeprägter Form gesundheitlich von Nachteil, da die Sohle bei vollelastischer Rückgabe der eingeprägten Belastung mit der gleichen Kraft auf den Fuß "zurückschlägt", mit der sie zuvor beim Aufsetzen belastet worden ist. Hierdurch entstehen insbesondere Schädigungen im Bereich der Achillessehne und der Kniegelenke.It is also known that the spring elasticity of the sole materials of the known outsoles produces a so-called "catapult effect" by accelerating the foot upward with a force corresponding to its compression in the amount of local stress reduction during the rolling process. Although this catapult effect is considered to be conducive to mileage, it is disadvantageous to health in a pronounced form since the sole "strikes back" on the foot with the same force with which it was previously loaded when it was put on when the impressed load was returned fully elastic. This causes damage in particular in the area of the Achilles tendon and knee joints.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Laufsohle der eingangs genannten Art zu schaffen, die auf einfachere Weise eine Anpassung der Dämpfungsfähigkeit der Laufsohle an unterschiedliche Körpergewichte der Läufer ermöglicht, ohne daß der Läufer hierzu selbst eingreifen muß. Darüber hinaus soll die Laufsohle einen Abbau der gesundheitsschädlichen Belastungsspitze aufgrund des Katapulteffekts bewirken.The invention is therefore based on the object of providing an outsole of the type mentioned at the outset, which makes it easier to adapt the damping ability of the outsole to different body weights of the runners without the runners having to intervene themselves. In addition, the outsole is intended to reduce the harmful peak load due to the catapult effect.
Erfindungsgemäß wird diese Aufgabe gelöst durch die Ausgestaltung gemäß dem Kennzeichen des Patentanspruches 1.According to the invention, this object is achieved by the configuration according to the characterizing part of patent claim 1.
Dadurch, daß der Dämpfungskörper aus einer Vielzahl von im unbelasteten Zustand sich nur bereichs- oder punktweise aneinander abstützenden Einzelkörpern aus einem elastischen Werkstoff besteht, die direkt aneinander anliegen können oder durch zwischengeschaltetes elastisches Material miteinander verbunden sind, ergibt sich ein progressives Federverhalten. Die Erfindung geht dabei von der im Prinzip bekannten Überlegung aus, daß durch ein progressive Federkennung des elastischen Dämpfungskörpers dieser selbsttätig eine Anpassung an unterschiedliche Körpergewichte der Läufer bewirkt. Denn bei niedriger Belastung kann durch die dort vorhandene weiche Federung ein ausreichender Federweg erzielt werden, während die Zunahme des Federweges mit steigender Belastung entsprechend der progressiv ansteigenden Federkennung immer geringer wird, so daß ein schwerer Läufer mit der Ferse relativ weniger in die Laufsohle einsackt. In diesem Sinn erweist sich ein aus einer Vielzahl von kleinen Einzelkörpern bestehender Dämpfungskörper als eine überraschend einfache Lösung für ein progressives Federverhalten. Denn die Einzelkörper, die vorzugsweise Kugeln sind, jedoch auch Würfel, Zylinder, Quader oder sonstige symmetrische oder asymmetrische Gebilde sein können, stützen sich im unbe lasteten Zustand, in welchem sie die Ausnehmung unter der Fersenaufstandsfläche normalerweise ganz ausfüllen, aufgrund ihrer Gestalt nur punkt-, linien- oder bereichsweise aneinander ab. Sie erzeugen dadurch Zwischenräume in dem durch ihre Gesamtheit gebildeten Dämpfungskörper. Infolge dieser nur kleinflächigen Anlage aneinander wird die auf sie ausgeübte Belastung in eine entsprechende Vielzahl von Einzelkräften aufgeteilt, die zunächst eine örtlich hohe Verformung der Einzelkörper zur Folge haben.Mit zunehmender Verformung wächst jedoch die Kontakt- und Stützfläche zwischen den Einzelkörpern, so daß die Nachgiebigkeit immer geringer wird. Erst in dem Zeitpunkt, in dem durch die elastische Verformung der Einzelkörper sämtliche Zwischenräume aufgezehrt sind, d.h. die Einzelkörper "zu Block" stehen, verhält sich der Dämpfungskörper insgesamt wie ein kompakter elastischer Körper mit angenähert linearer Federkennung.The fact that the damping body consists of a large number of individual bodies which are only supported in regions or points against one another in an unloaded state and which can lie directly against one another or are connected to one another by interposed elastic material, results in a progressive spring behavior. The invention is based on the principle known in principle that progressive spring detection of the elastic damping body automatically adapts it to different body weights of the runners. Because at low loads, the existing soft suspension can provide sufficient travel, while the increase in travel increases with increasing load in accordance with the progressively increasing spring detection, so that a heavy runner sinks into the outsole relatively less. In this sense, a damping body consisting of a large number of small individual bodies proves to be a surprisingly simple solution for a progressive spring behavior. This is because the individual bodies, which are preferably spheres, but can also be cubes, cylinders, cuboids or other symmetrical or asymmetrical structures, support each other loaded condition, in which they normally completely fill the recess under the heel contact surface, due to their shape only point, line or area to each other. As a result, they create gaps in the damping body formed by their entirety. As a result of these only small-area contact with one another, the load exerted on them is divided into a corresponding number of individual forces, which initially result in locally high deformation of the individual bodies. However, with increasing deformation, the contact and support surface between the individual bodies increases, so that the flexibility is getting lower. It is only at the point in time when all of the intermediate spaces are consumed by the elastic deformation of the individual bodies, ie the individual bodies are “in block”, that the damping body behaves overall like a compact elastic body with approximately linear spring detection.
Die Progressivität der Federkennlinie des erfindungsgemässen Dämpfungskörpers lässt sich durch Wahl der Grösse der Einzelkörper bestimmen. Zweckmässigerweise liegen die Grenzen der Haupt-Querabmessung bzw. des Durchmessers der Einzelkörper bei 2 und 12 mm. Bevorzugt wird jedoch eine Grösse von 3 bis 8 mm.The progressivity of the spring characteristic of the damping body according to the invention can be determined by choosing the size of the individual bodies. The limits of the main transverse dimension or the diameter of the individual bodies are expediently 2 and 12 mm. However, a size of 3 to 8 mm is preferred.
Mit der hierdurch auf einfache Weise erzielbaren progressiven Federkennung des Dämpfungskörpers geht ein bedeutsamer weiterer Vorteil dieser Lösung einher. Da sich die Einzelkörper in der Ausnehmung bei auftretender Belastung relativ zueinander auch verschieben können, wird ein Teil der eingeprägten Bewegungsenergie in Reibung umgesetzt. Dies bewirkt, daß bei der Entlastung des Dämpfungskörpers dieser die auf ihn einwirkende Kraft nicht voll an die Ferse des Läufers zurückgibt, sondern nur in einem etwas geringeren Ausmaß. Hierdurch wird zwar der normalerweise erwünschte Katapulteffekt, der den Läufer bei weiterem Fortgang der Abrollphase wieder etwas nach oben beschleunigt, vermindert. Jedoch hat sich gezeigt, daß ein voll-elastisches Verhalten des Dämpfungskörpers, der bei der Entlastung die zuvor abgefangene Kraft wieder voll an die Ferse zurückgibt, gesundheitliche Beeinträchtigungen im Fersen- und Achillessehnenbereich zur Folge haben kann. Dadurch, daß sich bei dem erfindungsgemässen Dämpfungskörper dessen Einzelkörper bei und nach der Entlastung erst wieder - unter entsprechender Überwindung von Reibung - in ihre Ausgangslage zurückbewegen müssen, wird dem erwähnten Katapulteffekt mit positiver Auswirkung die Spitze genommen. Dies gilt auch, wenn aus Zweckmässigkeitsgründen die Einzelkörper untereinander zur besseren Handhabung beim Produktionsvorgang der Laufsohle durch ein Klebe- oder Bindemittel leicht aneinander gebunden oder sogar einstückig mit und in einer dünnen Membran gegenseitig fixiert sind. Denn dieses Klebe- oder Bindemittel, das z.B. ein Silikon-Kautschuk sein kann, bzw. die aus dem gleichen Werkstoff wie die Einzelkörper bestehende Membran ist selbst in erheblichem Ausmaß elastisch nachgiebig und verhindert im wesentlichen nur ein Auseinanderfallen der Einzelkörper, jedoch nicht deren Relativbeweglichkeit.The progressive spring detection of the damping body which can be achieved in a simple manner in this way is accompanied by a significant further advantage of this solution. Since the individual bodies can also move relative to one another in the recess when a load occurs, part of the impressed kinetic energy is converted into friction. This has the effect that when the damping body is relieved, it does not fully return the force acting on it to the runner's heel, but only to a somewhat lesser extent. This will the normally desired catapult effect, which accelerates the runner slightly upwards as the rolling phase continues, is reduced. However, it has been shown that a fully elastic behavior of the damping body, which fully returns the previously intercepted force to the heel when relieved, can result in health problems in the heel and Achilles tendon area. The fact that the individual bodies of the damping body according to the invention only have to move back to their starting position during and after the relief - with a corresponding overcoming of friction - the above-mentioned catapult effect is taken away with a positive effect. This also applies if, for reasons of expediency, the individual bodies are easily bound to one another by an adhesive or binder for better handling during the production process of the outsole, or are even fixed to one another in one piece with and in a thin membrane. This adhesive or binding agent, which can be a silicone rubber, for example, or the membrane made of the same material as the individual body, is itself elastically flexible to a considerable extent and essentially only prevents the individual bodies from falling apart, but not their relative mobility.
Wie bereits erwähnt, können zum Zweck der besseren Handhabung die Einzelkörper, z.B. Kugeln, einstückig mit einer dünnen Membran geformt sein, die sie in einem so geringen Abstand voneinander fixiert, daß zwischen den Einzelkörpern allenfalls winzige Brücken bestehen. Im Fall von Einzelkörpern mit allseitig gewölbter Oberfläche, z.B. Kugeln, ist jedoch auch bei der Fixierung mittels einer Membran eine direkte Anlage der Kugeln aneinander möglich, da die Membran sich nur durch die aufgrund der Form ohnehin bestehenden Zwischenräume zu erstrecken braucht. Um die erwünschte Relativbeweglichkeit der Einzelkörper und die von diesen gebildeten Zwischenräume nicht zu beeinträchtigen, sollte die Membran sehr dünn gehalten werden, beispielsweise mit einer Dicke von nur wenigen Zehntel Millimeter.As already mentioned, for the purpose of better handling, the individual bodies, for example balls, can be formed in one piece with a thin membrane, which fixes them at such a small distance from one another that there are at most tiny bridges between the individual bodies. In the case of single bodies with a curved surface on all sides, for example spheres, direct attachment of the spheres to one another is also possible in the case of fixation by means of a membrane, since the membrane can only be separated by the gaps which already exist due to the shape needs to stretch. In order not to impair the desired relative mobility of the individual bodies and the spaces formed by them, the membrane should be kept very thin, for example with a thickness of only a few tenths of a millimeter.
Anstelle einer Membran kann die gewünschte Bindung der Einzelkörper aneinander auch durch winzige stäbchen- oder ringförmige Brücken bewirkt werden, die ebenfalls beispielsweise im Spritzgießverfahren einstückig mit den Einzelkörpern hergestellt sein können. Sowohl die Membran als auch diese brückenförmige Matrix kann eben oder räumlich ausgebildet sein. Eine ebene Ausbildung, bei der auch entsprechend die Einzelkörper in einer Ebene liegen, ist insofern zweckmässig, als hierdurch der Dämpfungskörper insgesamt durch mehrere Schichten dieser so gebundenen Einzelkörper aufgebaut werden kann.Instead of a membrane, the desired binding of the individual bodies to one another can also be brought about by tiny rod-shaped or ring-shaped bridges, which can likewise be produced in one piece with the individual bodies, for example by injection molding. Both the membrane and this bridge-shaped matrix can be flat or spatial. A flat design, in which the individual bodies also lie in one plane, is expedient insofar as the damping body can be constructed as a whole by several layers of these individual bodies bound in this way.
Ein Ausführungsbeispiel der Erfindung ist nachfolgend anhand der beiliegenden Zeichnungen näher erläutert. In den Zeichnungen zeigen:

which the individual bodies are bound together.
Die in den Zeichnungen gezeigte Laufsohle besteht aus einer Zwischensohle 1 aus elastischem Kunststoff, z.B. Polyurethan mit einer Shore-A-Härte von 25 bis 65 (entsprechend Shore-C von 40 bis 80), einer damit laufseitig verbundenen Verschleißsohle 2 beispielsweise aus Gummi, die eine nicht näher gezeigte Profilierung aufweisen kann, sowie aus einer Fersenbettschale 3, die mit der Fußseite der Zwischensohle 1 im Fersenbereich verbunden ist und eine Shore-Härte in gleicher Grössenordnung wie die Zwischensohle oder etwas darüber haben kann.The outsole shown in the drawings consists of a midsole 1 made of elastic plastic, e.g. Polyurethane with a Shore A hardness of 25 to 65 (corresponding to Shore-C from 40 to 80), a wear sole 2 connected to it on the running side, for example made of rubber, which may have a profiling (not shown in more detail), and a heel bed shell 3, which with the foot side of the midsole 1 is connected in the heel area and may have a Shore hardness of the same order of magnitude as the midsole or slightly above it.
Unterhalb der Fersenaufstandsfläche, d.h. dem in Fig. 1 mit A angedeuteten Bereich, in welchem das Fersenbein des Läufers die Fersenbettschale 3 belastet, ist eine Ausnehmung 4 in der Zwischensohle 1 eingeformt, die sich von der Trennfläche zwischen der Verschleißsohle 2 und der Zwischensohle 1 ausgehend nach oben erstreckt. Die Ausnehmung 4
endet in einem Abstand von nur etwa 0 bis 2 mm vor der Trennfläche zwischen der Fersenbettschale 3 und der Zwischensohle 1. Der Durchmesser der Ausnehmung 4 beträgt in dem gezeigten Ausführungsbeispiel etwa 3,5 bis 4 cm; ihre Höhe etwa 12,5 bis 13 mm.A

Fig. 3 zeigt einen Dämpfungskörper, der aus zwei Kugelschichten 51 und 52 besteht. Jede der beiden Kugelschichten 51, 52 ist dadurch gebildet, daß in einer Ebene angeordnete Kugeln 5 durch sehr kleine Verbindungsstege 53 aneinandergebunden sind, die einstückig mit den Kugeln geformt, z.B. spritz gegossen sind. Durch diese Matrix von Verbindungsstegen 53 sind die Kugeln so gehalten, daß jede Kugelschicht 52 leicht handhabbar ist. In dem gezeigten Ausführungsbeispiel haben beide Kugelschichten 51, 52 einen im wesentlichen kreisförmigen Umriß von einer Grösse, daß sie in die entsprechend ausgebildete Ausnehmung 4 passen und diese weitgehend ausfüllen (Fig.1 ). Dabei weist die obere Kugelschicht 51 im Kreismittelpunkt eine Kugel auf, währen der Mittelpunkt der unteren Kugelschicht 52 unbesetzt ist. Auf diese Weise stehen die Kugeln der beiden Schichten "auf Lücke" zueinander, da die Kugelgrösse gleich ist, so daß sich der aus den Fig. 1 und 3 ersichtliche kegelstumpfförmige Aufbau des Dämpfungskörpers ergibt. Diesem Aufbau ist die Form der Ausnehmung 4 angepasst.Fig. 3 shows a damping body, which consists of two
Im Ausführungsbeispiel haben die Kugeln einen Durchmesser von etwa 7 mm, woraus sich eine Gesamtanzahl von etwa 40 Kugeln des Dämpfungskörpers ergibt.In the exemplary embodiment, the balls have a diameter of approximately 7 mm, which results in a total number of approximately 40 balls of the damping body.
Bei der Belastung während des Laufes wird über den über der Ausnehmung 4 befindlichen Teil der Fersenbettschale 3 und ggf. der verbleibenden Wandung der Zwischensohle 1 eine Druckkraft auf die Ansammlung von Kugeln 5 ausgeübt. Diese Druckkraft führt, ausgehend vom Zentrum der Belastung, d.h. normalerweise des unteren Scheitelpunktes des Fersenbeins, zu einer zunehmenden Aneinanderdrückung der Kugeln 5 nach unten und in radialer Richtung. Hierdurch wird ein Federweg erzeugt, während aufgrund der Elastizität der Kugeln 5 eine der Belastung entsprechende Rückstellkraft wirkt. Mit zunehmender Belastung wird die Reaktionskraft der Kugeln, wie eingangs geschildert, progressiv grösser, so daß der Federweg nicht linear zur Belastung ist, sondern die Federwegzunahme mit steigender Belastung abnimmt.During the load during the run, a pressure force is exerted on the accumulation of
Im Rahmen der Erfindung können Abweichungen von den vorstehend beschriebenen Ausführungsbeispielen getroffen werden. So kann beispielsweise die Form der Ausnehmung, in der der Dämpfungskörper angeordnet ist, beliebig sein und anstelle einer Kreisfläche eine ovale oder polygonal berandete Grundfläche haben. Weiterhin kann die zwischen den Einzelkörpern, hier Kugeln, bestehende Reibung gezielt beeinflusst werden, indem deren Oberfläche bewusst rauh oder weniger rauh gehalten wird. Bei grösserer Rauhigkeit und dadurch erhöhter Reibung nehmen die Kugeln mehr Energie auf und verringern dadurch die Kraftspitze des Katapulteffekts in stärkerem Ausmaß. Es versteht sich weiterhin, daß auch bei Anordnung der Kugeln in einer Matrix der Dämpfungskörper nicht auf die in Fig. 3 gezeigte Gestaltung beschränkt ist.Within the scope of the invention, deviations from the exemplary embodiments described above can be made. For example, the shape of the recess in which the damping body is arranged can be arbitrary and have an oval or polygonal base area instead of a circular area. Furthermore, the friction existing between the individual bodies, here balls, can be influenced in a targeted manner by deliberately keeping the surface rough or less rough. With greater roughness and thus increased friction, the balls absorb more energy and thereby reduce the force peak of the catapult effect to a greater extent. It is further understood that even when the balls are arranged in a matrix, the damping body is not limited to the design shown in FIG. 3.
