Dieser bekannte Schuh (GB 2 200 030 A oder GB 2 288 720 A) wie auch andere kenventionelle Schuhe bestehen aus einer Sohle und einem Obermaterial, das den auf der Sohle aufliegenden Fuß umschließt. Die Sohlen von Schuhen weisen oftmals Dämpfungsmittel auf, mit denen die beim Laufen auf den Fuß bzw. auf den gesamten Körper des Läufers ausgeübte Belastung gemildert werden soll. Bekannte Dämpfungsmittel sind beispielsweise Luftpolster oder mit Gel gefüllte Hohlräume.This well-known shoe (GB 2 200 030 A or GB 2 288 720 A) as well as other conventional shoes made of a sole and an upper, which the on encloses the foot on the sole. The soles of Shoes often have damping agents with which that when walking on the foot or on the whole Body of the runner exerted stress relieved shall be. Known damping agents are for example air cushions or filled with gel Cavities.

Ergänzend sei in bezug auf derartige bekannte Schuhe auch auf die Druckschrift WO 87/03789 A1 hingewiesen, in der die Möglichkeit offenbart ist, ein oder mehrere Ventile anzuordnen, die in bezug auf die Ausnehmung den Luftaustausch regeln. Die Möglichkeit der Anordnung eines Luftbalgs in bezug auf die Ausnehmung ist ebenfalls bereits bekannt (GB 2 150 010 A) .Supplementary to such known shoes also referred to the publication WO 87/03789 A1, in which the possibility is revealed, one or to arrange several valves, which with respect to the Regulate the air exchange in the recess. The possibility the arrangement of an air bellows with respect to the Recess is also already known (GB 2 150 010 A).

Des weiteren ist eine Sohle mit einer Vielzahl von Dämpfungselementen bekannt (EP 0 695 514 A1). Diese Sohle weist im Fersenbereich, im Mittelfußbereich und im Ballenbereich mehrere sich in Querrichtung erstreckende Löcher auf, die als Dämpfungspolster dienen sollen. Diese Löcher sind in unterschiedlicher Form und Größe ausgebildet und weisen einen dementsprechend harten bzw. weichen Dämpfungseffekt auf. In einer Ausführungsform ist in die Sohle vom hinteren Ende eine Ausnehmung eingebracht, die seitlich offen ist, so daß der unterseitige Bereich der Sohle eine nach hinten frei vorstehende Platte bildet. Eine solche Sohle weist im Fersenbereich eine sehr weiche Dämpfungscharakteristik auf.Furthermore, a sole with a variety of Damping elements known (EP 0 695 514 A1). This Sole shows in the heel area, in the midfoot area and in the bale area several in the transverse direction extending holes that act as cushioning pads should serve. These holes are different Form and size and have a accordingly hard or soft damping effect on. In one embodiment, the sole is from introduced a recess in the rear end is open on the side, so that the underside area the sole is a plate protruding freely to the rear forms. Such a sole has a heel area very soft damping characteristics.

Es ist auch eine Sohle für einen Übungsschuh bekannt (DE 94 13 496 01), mit dem das Gehen in der Ebene zu Trainingszwecken erschwert ist. Diese Sohle ist in dem dem Absatz zugeordneten Bereich ausgenommen, so daß der Benutzer des Schuhs im wesentlichen nur im Bereich der Ballen auftreten kann. Hierdurch soll ein Effekt wie beim Bergaufwärtsgehen an einer Steigung in einer Größenordnung von 15 Grad oder wie beim Treppensteigen erzielt werden. Ein solcher Schuh, der das Ballenlaufen fördert, ist unter gesundheitlichen Aspekten ungeeignet, da insbesondere beim Ballenlaufen der Fuß bzw. der Schuh mit gestrecktem Bein am Boden aufgesetzt wird und die Stoßbelastung unmittelbar auf die Knie- und Hüftgelenke und die Wirbelsäule übertragen wird.A sole for a training shoe is also known (DE 94 13 496 01), with which walking in the plane to Training purposes is difficult. This sole is in except the area assigned to the paragraph, so that the user of the shoe essentially only in Area of the bale may occur. This is supposed to Effect like going uphill on a slope on the order of 15 degrees or as with Climbing stairs can be achieved. Such a shoe that promoting bale running is among health Aspects unsuitable, especially when Bale running the foot or the shoe with stretched Leg is placed on the floor and the shock load directly on the knee and hip joints and the Spine is transmitted.

Ausgehend von den vorgenannten Nachteilen und Unzulänglichkeiten der aus dem Stand der Technik bekannten Schuhe liegt der vorliegenden Erfindung die Aufgabe zugrunde, einen Schuh zu schaffen, mit dem die beim Laufen auftretenden Stoßbelastungen nicht oder in einem nur sehr geringen Maße auf die Knieund Hüftgelenke und auf die Wirbelsäule übertragen werden.Based on the aforementioned disadvantages and Shortcomings of the prior art known shoes, the present invention is the The task is to create a shoe with which the shock loads that occur when running or to a very small extent on the knees and Hip joints and transferred to the spine become.

Diese Aufgabe wird bei einem Schuh der eingangs genannten Art gemäß der Lehre der vorliegenden Erfindung dadurch gelöst, daß der Sohlenbelag im Bereich der Schwenkachse

  • biegsam ausgebildet ist und/oder
  • eine Verjüngung aufweist.
This object is achieved in a shoe of the type mentioned in the teaching of the present invention in that the sole covering in the region of the pivot axis
  • is flexible and / or
  • has a taper.

Der Schuh gemäß der vorliegenden Erfindung weist eine aus einem Sohlenkörper und aus einem Sohlenbelag ausgebildete Sohle auf, wobei eine sich etwa vom Mittelfußbereich zum Fersenbereich erstreckende Ausnehmung im Bereich zwischen dem Sohlenkörper und dem Sohlenbelag vorgesehen ist, so daß der der Ausnehmung zugeordnete Bereich des Sohlenbelags beim Aufsetzen auf einen Untergrund nach oben um eine Schwenkachse weggeschwenkt wird, wodurch der Schuh sehr weich auf den Untergrund aufgesetzt wird.The shoe according to the present invention has one from a sole body and from a sole covering trained sole, one of which is about Metatarsal area extending to the heel area Recess in the area between the sole body and the sole covering is provided so that the Area of the sole covering assigned to the recess Put on a surface up one Swivel axis is pivoted away, causing the shoe is placed very softly on the surface.

Wenn der Schuh im Bereich der Schwenkachse auf den Untergrund aufgesetzt wird, kippt er um die Schwenkachse mit dem Ballen- bzw. Zehenbereich auf den Untergrund. Hierdurch wird der Fuß und der Unterschenkel etwas nach vorne versetzt, wodurch das Knie selbsttätig leicht gebeugt wird. Ein im Knie gebeugtes Bein nimmt die Stoßbelastung durch das Beinskelett und die umgebenden Muskeln auf, ohne daß die Stoßbelastung auf die Gelenke bzw. auf die Wirbelsäule übertragen wird.If the shoe on the swivel axis on the Is placed on the ground, it tilts around Swivel axis with the ball or toe area the underground. This will make the foot and the Lower leg slightly shifted forward, which means that Knee is automatically bent slightly. One in the knee bent leg takes the shock load from the Leg skeleton and the surrounding muscles without the impact load on the joints or on the Spine is transmitted.

Der Schuh gemäß der vorliegenden Erfindung bewirkt somit einen abrundenden Effekt, das heißt ein Abrollen während des Aufsetzens auf den Untergrund, wodurch die auf die empfindlichen Gelenke bzw. auf die Wirbelsäule ausgeübte Stoßbelastung wesentlich vermindert wird.The shoe according to the present invention works thus a rounding effect, that is a Unrolling while laying on the ground, whereby the on the sensitive joints or on the impact on the spine is significant is reduced.

Auch in der Standphase wird der Träger des Schuhs in eine therapeutische Grundhaltung, das heißt in eine Haltung mit angewinkelten Knien gezwungen, wodurch die Wirbelsäule auch im Stand entlastet wird.The wearer of the shoe is also in the stance phase a therapeutic attitude, that is, in a Forced posture with bent knees, causing the spine is relieved even when standing.

Der Erfindung liegt somit die Erkenntnis zugrunde, daß bei herkömmlichen Schuhen trotz aufwendiger und teurer Dämpfungselemente die Stoßbelastung unmittelbar auf die Gelenke und auf die Wirbelsäule übertragen wird, da mit diesen Schuhen der Fuß bzw. der Schuh mit gestrecktem Bein auf den Untergrund aufgesetzt werden kann.The invention is therefore based on the knowledge that that with conventional shoes despite complex and expensive damping elements the shock load directly on the joints and on the spine is transmitted because with these shoes the foot or the shoe with the leg straight on the ground can be put on.

Die Sohlenoberseite schließt mit der Sohlenunterseite einen Winkel a ein, der im Bereich von etwa 8 Grad bis etwa 20 Grad liegt.The entire sole 2 has a bale or Toe area 8 increasing towards the heel area 6 Thickness so that the sole 2 in the side view forms a wedge. The top of the sole closes the bottom of the sole an angle a, which in Range is from about 8 degrees to about 20 degrees.

Zwischen dem Sohlenkörper 10 und dem Sohlenbelag 11 ist eine sich vom Mittelfußbereich 7 zum Fersenbereich 8 keilförmig aufweitende Ausnehmung 13 vorgesehen. Der Sohlenkörper 10 bildet angrenzend an die Ausnehmung 13 eine Anschlagfläche 15.Between the sole body 10 and the sole covering 11 is one from the midfoot area 7 to Heel area 8 wedge-shaped widening recess 13 intended. The sole body 10 adjoins the recess 13 has a stop surface 15.

Der Sohlenbelag 11 steht angrenzend an eine zum Ballen- bzw. Zehenbereich 8 zeigende Ansnehmungsspitze 13a der Ausnehmung 13 frei nach hinten vor, wobei dieser frei nach hinten vorstehende Bereich des Sohlenbelags 11 ein Schwenkelement 18 bildet, das um den der Ausnehmungsspitze 13a benachbarten Verbindungsbereich zwischen dem Schwenkelement 18 und dem übrigen Sohlenbelag 11 nach oben gegen die Anschlagfläche 15 des Sohlenkörpers 10 schwenkbar ist. Durch den Sohlenbelag 11 verläuft somit in Querrichtung benachbart zur Ausnehmungsspitze 13a eine Schwenkachse 20, um die das Schwenkelement 18 schwenkbar angeordnet ist.The sole covering 11 is adjacent to one Acceptance tip 13a of the ball or toe region 8 Recess 13 freely to the rear, which is free rearward protruding area of the sole covering 11 forms a pivot member 18 which around the Recess tip 13a adjacent connection area between the pivot member 18 and the rest Sole covering 11 upwards against the abutment surface 15 of the sole body 10 is pivotable. By the Sole covering 11 thus runs in the transverse direction adjacent to the recess tip 13a Swivel axis 20 about which the swivel element 18 is pivotally arranged.

Ein Schwenkwinkel β zwischen der Anschlagfläche 15 und dem Schwenkelement 18 liegt im Bereich von etwa 10 Grad bis etwa 30 Grad, insbesondere im Bereich von etwa 15 Grad bis etwa 20 Grad. Die Spitze 13a der Ausnehmung 13 und somit die Schwenkachse 20 sind im Bereich zwischen der Längsmitte des Schuhs 1 und dem Fersenbereich 6, der sich in etwa über ein Drittel der Länge des Schuhs 1 erstreckt, angeordnet.A swivel angle β between the stop surface 15 and the pivot element 18 is in the range of about 10 degrees to about 30 degrees, especially in the range of about 15 degrees to about 20 degrees. The tip 13a of the Recess 13 and thus the pivot axis 20 are in the Area between the longitudinal center of the shoe 1 and the Heel area 6, which is approximately over a third the length of the shoe 1, arranged.

Der Sohlenbelag 11 weist insbesondere im Bereich der Schwenkachse 20 und des Schwenkelements 18 eine beachtliche Formstabilität und/oder Biegesteifigkeit auf und ist faserbewehrt, wodurch der Sohlenbelag 11 eine erhebliche Eigensteifigkeit aufweist.The sole covering 11 has in particular in the area of Swivel axis 20 and the swivel element 18 a considerable dimensional stability and / or bending stiffness and is fiber-reinforced, whereby the sole covering 11 has considerable inherent rigidity.

Wie aus der Darstellung der Figur 2 hervorgeht, berührt der Schuh 1 beim Laufen aufgrund der Keilform der gesamten Sohle 2 beim Aufsetzen auf einen Untergrund mit seinem Sohlenbelag 11 im Fersenbereich 6 und somit mit seinem Schwenkelement 18 den Untergrund 22. Hierbei wird das Schwenkelement 18 des Sohlenbelags 11 um die Schwenkachse 20 gegen die Anschlagfläche 15 gedrückt.As can be seen from the illustration in FIG. 2, touches the shoe 1 when running due to the wedge shape the entire sole 2 when placed on one Underground with its sole covering 11 in the heel area 6 and thus with its swivel element 18 Underground 22. Here, the pivot element 18 of the Sole covering 11 about the pivot axis 20 against the Stop surface 15 pressed.

Diese Schwenkbewegung des Schwenkelements 18 erzeugt trotz der beachtlichen Formstabilität des Sohlenbelags 11 ein sehr weich, nachgebendes Aufsetzen des Schuhs 1 auf den Untergrund 22. Die Rückstellkraft des Sohlenbelags 11 ist so gewählt, daß höchstens dreißig Prozent, nach Möglichkeit nur zehn Prozent des Gewichts des Läufers (beispielsweise 65 Kilogramm bis 75 Kilogramm), für das der Schuh 1 ausgelegt ist, genügen, um das Schwenkelement 18 gegen die Anschlagfläche 15 zu drücken.This pivoting movement of the pivot element 18 generates despite the form stability of the Sole 11 a very soft, yielding Put the shoe 1 on the surface 22. Die Restoring force of the sole covering 11 is selected that at most thirty percent, if possible only ten percent of the weight of the runner (for example 65 kg to 75 kg) for which the shoe 1 is designed to suffice for the swivel element 18 to press against the stop surface 15.

Schlägt das Schwenkelement 18 an der Anschlagfläche 15 an (vgl. Figur 2), so ist der sich von der Schwenkachse 20 zum Ballen- bzw. Zehenbereich 8 erstreckende Bereich der Sohle 2 bzw. des Sohlenbelags 11 um den Schwenkwinkel β gegenüber dem Untergrund 22 nach vorne oben geneigt. Der Sohlenbelag 11 weist bei abgewinkeltem Schwenkelement 18 einen stumpfen Winkel von nahezu 180 Grad im Bereich der Schwenkachse 20 auf.Strikes the pivot member 18 on the stop surface 15 (cf. FIG. 2), so it is different from the Swivel axis 20 to the ball or toe area 8 extending area of the sole 2 or Sole covering 11 by the pivot angle β compared to that Surface 22 inclined upwards to the front. The Sole covering 11 has an angled pivot element 18 an obtuse angle of almost 180 degrees in Range of the pivot axis 20.

Beim Anschlag des Schwenkelements 18 an der Anschlagfläche 15 ist der weiche Aufsetzvorgang im Fersenbereich 6 beendet, und die vom Fuß des Läufers auf die Sohle 2 ausgeübte Belastung verteilt sich etwa gleichmäßig über die gesamte Länge der Sohle 2. Hierdurch und durch den in Laufrichtung gerichteten Impuls des Läufers kippt der Schuh 1 um die Schwenkachse 20 nach vorne ab und liegt mit seinem vorderen Bereich des Sohlenbelags 11 auf dem Untergrund 22 auf.When the swivel element 18 stops on the Stop surface 15 is the soft placement process in Heel area 6 ends, and that of the runner's foot load exerted on the sole 2 is distributed approximately evenly over the entire length of the sole 2. As a result and through the direction of travel The impulse of the runner tilts the shoe 1 around Swivel axis 20 to the front and lies with his front area of the sole covering 11 on the Underground 22 on.

Dieses Abkippen des Schuhs 1 bewirkt, daß der Fuß und der Unterschenkel des Läufers in Laufrichtung nach vorne etwas versetzt werden, wodurch das Knie zwischen dem Unterschenkel und dem Oberschenkel leicht gebeugt wird. Die Maximalbelastung auf den Fuß bzw. auf die Sohle 2 tritt erst nach dem Abkippen des Schuhs 1 bzw. nach dem Beugen des Knies des Läufers auf, so daß der durch das Auftreffen auf dem Untergrund 22 erzeugte Rückstoß auf ein im Knie bereits abgewinkeltes Bein trifft, das elastisch federnd um das Kniegelenk mit seinem Beinskelett und den Muskeln die Stoßbelastung schonend aufnehmen kann.This tilting of the shoe 1 causes the foot and the lower leg of the runner in the running direction be displaced slightly at the front, causing the knee between the lower leg and the thigh is slightly bent. The maximum load on the foot or on the sole 2 occurs only after the tipping Shoe 1 or after bending the runner's knee so that by hitting the Underground 22 generated recoil to one in the knee already angled leg that is elastic bouncy around the knee joint with its leg skeleton and absorb the shock load gently on the muscles can.

Der Schuh 1 gemäß der vorliegenden Erfindung bewirkt somit ein automatisches Abrollen des Fußes beim Laufen, wodurch im Vergleich zu herkömmlichen Schuhen eine wesentlich schonendere Übertragung der Stoßbelastung auf den Körper bewirkt wird.The shoe 1 according to the present invention effects thus an automatic rolling of the foot when Running, which is compared to conventional shoes a much gentler transmission of the Impact on the body is caused.

Eine zweite Ausführungsform des Schuhs gemäß der vorliegenden Erfindung ist in Figur 3 gezeigt. Dieser Schuh 1 entspricht im wesentlichen dem vorstehend beschriebenen Schuh 1; demgemäß sind gleiche oder ähnliche Bestandteile mit identischen Bezugszeichen versehen.A second embodiment of the shoe according to the The present invention is shown in Figure 3. This Shoe 1 essentially corresponds to the above described shoe 1; accordingly, are the same or Similar components with identical reference numbers Mistake.

Der Schuh 1 gemäß Figur 3 weist in der keilförmigen Ausnehmung 13 ein Materialelement in Form eines Materialkeils 25 auf, das aus einem offenzelligen Schaumstoff gebildet ist. Dieser Materialkeil 25 ist an der Anschlagfläche 15 des Sohlenkörpers 10 sowie an dem Schwenkelement 18 mittels einer Klebeverbindung angebracht.The shoe 1 according to FIG. 3 has a wedge shape Recess 13 a material element in the form of a Material wedge 25 on that from an open cell Foam is formed. This material wedge 25 is on the stop surface 15 of the sole body 10 and on the swivel element 18 by means of a Adhesive connection attached.

Der Sohlenbelag 11 ist im Bereich der Schwenkachse 20 durch einen Schlitz 27 unterteilt. Im Rahmen der Erfindung liegt selbstverständlich auch eine Ausführungsform ohne Schlitz (vgl. beispielsweise die in den Figuren 5 und 6 gezeigte vierte Ausführungsform der vorliegenden Erfindung).The sole covering 11 is in the region of the pivot axis 20 divided by a slot 27. As part of the Invention is of course also a Embodiment without slot (see, for example, the fourth shown in Figures 5 and 6 Embodiment of the present invention).

Zweckmäßig ist, daß der Sohlenbelag 11 im Bereich der Schwenkachse 20 biegsam, etwa durch eine Verjüngung, ausgebildet ist, denn bei diesem Ausführungsbeispiel des Schuhs 1 ist es vorteilhaft, daß während der Aufsetzphase des Schuhs 1 im Fersenbereich 6 auf den Untergrund 22 die Rückstellkraft des Schwenkelements 18 möglichst lediglich vom Materialkeil 25 aufgebracht wird, um ein möglichst weiches Aufsetzen des Schuhs 1 auf den Untergrund 22 sicherzustellen.It is useful that the sole covering 11 in the area of Pivot axis 20 flexible, for example by a taper, is formed, because in this embodiment of the shoe 1, it is advantageous that during the Installation phase of the shoe 1 in the heel area 6 on the Background 22 the restoring force of the swivel element 18 if possible only from the material wedge 25 is applied to make it as soft as possible ensure the shoe 1 on the surface 22.

In den Sohlenkörper 10 ist eine Verstärkungsplatte 29 eingesetzt, die sich etwa von der Längsmitte des Schuhs 1 bis in den rückwärtigen Fersenbereich 6 erstreckt. Die Verstärkungsplatte 29 besteht aus einer Metallplatte oder aus einer faserverstärkten Kunststoffplatte und ist mit Abstand oberhalb eines Druckverteilungsteils 16 angeordnet, wobei die Verstärkungsplatte 29 an die Wölbung des Druckverteilungsteils 16 angepaßt ist. Die Verstärkungsplatte 29 erstreckt sich in Querrichtung über etwa drei Fünftel bis vier Fünftel der Breite des Schuhs 1 und gewährleistet während der Aufsetzphase, während der das Schwenkelement 18 gegen die Anschlagfläche 15 gedrückt wird, daß der Sohlenkörper 10 durch die Ferse nicht heruntergekippt wird.A reinforcing plate 29 is in the sole body 10 used, which is approximately from the longitudinal center of the Shoes 1 to the rear heel area 6 extends. The reinforcing plate 29 consists of a metal plate or a fiber-reinforced one Plastic plate and is a distance above one Pressure distribution part 16 arranged, the Reinforcement plate 29 to the curvature of the Pressure distribution part 16 is adapted. The Reinforcing plate 29 extends in the transverse direction about three fifths to four fifths of the width of the shoe 1 and ensures during the Aufsetzphase, during which the pivoting element 18 against the stop surface 15 is pressed that the Sole body 10 does not tip over by the heel becomes.

Eine dritte Ausführungsform der Erfindung ist in Figur 4 gezeigt. Dieser Schuh 1 weist im wesentlichen den gleichen Aufbau wie die vorstehend beschriebenen Schuhe 1 auf; demgemäß sind gleiche oder ähnliche Bestandteile mit identischen Bezugszeichen versehen.A third embodiment of the invention is in Figure 4 shown. This shoe 1 essentially has the same structure as that described above Shoes 1 on; accordingly are the same or similar Provide components with identical reference numerals.

Die keilförmige Ausnehmung zwischen der Anschlagfläche 15 und dem Schwenkelement 18 ist von einem Luftbalg 31 eingefaßt. In den Sohlenkörper 10 sind zwei Löcher 32 eingebracht, die mit ihrem einen Ende an der Anschlagfläche 15 und mit ihrem anderen Ende außenseitig am Sohlenkörper 10 münden. The wedge-shaped recess between the Stop surface 15 and the pivot member 18 is from an air bellows 31 bordered. In the sole body 10 are two holes 32 made with their one End at the stop surface 15 and with her other End on the outside on the sole body 10.

In jedem der beiden Löcher 32 ist jeweils ein Ventil 33 eingesetzt, das den Austritt der Luft aus dem Luftbalg 31 nach außen beschränkt, so daß beim Andrücken des Schwenkelements 18 in Richtung zur Anschlagfläche 15 durch den begrenzten Luftaustritt bei der Schwenkbewegung des Schwenkelements 18 ein vorbestimmter, relativ weicher Widerstand entgegengesetzt wird.There is a valve in each of the two holes 32 33 used to prevent air from escaping Air bellows 31 limited to the outside, so that when Pressing the swivel element 18 in the direction of Stop surface 15 due to the limited air outlet during the pivoting movement of the pivot element 18 predetermined, relatively soft resistance is opposed.

Wird der Druck, mit dem das Schwenkelement 18 gegen die Anschlagfläche 15 gedrückt wird, aufgehoben, so schwenkt das Schwenkelement 18 wieder in die Ausgangsstellung zurück, die in geradliniger Verlängerung des übrigen Sohlenbelags 11 verläuft, wobei die Ventile 33 sich öffnen und einen schnellen Luftstrom in den Luftbalg 31 erlauben.Is the pressure with which the pivot element 18 against the stop surface 15 is pressed, canceled pivots the swivel element 18 back into the Starting position back, that in a straight line Extension of the remaining sole covering 11 runs, the valves 33 open and a quick one Allow air flow into the air bellows 31.

Das Schwenkelement 18 des Sohlenbelags 11 ist einteilig mit dem übrigen Bereich des Sohlenbelags 11 ausgebildet und weist eine gewisse Formstabilität bzw. Biegesteifigkeit auf, so daß es selbsttätig nach einer Kompression des Luftbalgs 31 in die Ausgangsstellung zurückschwenkt.The pivot element 18 of the sole covering 11 is in one piece with the remaining area of the sole covering 11 trained and has a certain dimensional stability or bending stiffness so that it automatically after a compression of the air bellows 31 in the Starting position swings back.

Die vierte Ausführungsform gemäß Figur 5 entspricht im wesentlichen der zweiten Ausführungsform gemäß Figur 3, lediglich mit dem Unterschied, daß die Ausnehmung 13 nicht keilförmig, sondern im wesentlichen kreisabschnittförmig ausgebildet und mit einem Materialelement 25 aus offenporigem Kunststoff gefüllt ist.The fourth embodiment according to FIG. 5 corresponds essentially according to the second embodiment Figure 3, only with the difference that the Recess 13 not wedge-shaped, but in formed essentially in the form of a circular segment and with a material element 25 made of open-pore plastic is filled.

Hierbei ist die Sohle 2 gemäß einem erfindungswesentlichen Merkmal seitlich hochgezogen bzw. mit einer sehr dünnen seitlichen Abdeckung in Form von Seitenwänden aus Gummi versehen, die den Kunststoffkern nach außen hin schützend abdecken und sich balgartig leicht zusammendrücken lassen.Here, the sole 2 is according to one feature essential to the invention pulled up laterally or with a very thin side cover in Form of side walls made of rubber that the Cover the plastic core to protect it from the outside and can be easily compressed like a bellows.

Bei der vorliegenden Erfindung wird also die Wirkung der Ausnehmung 13 derart ausgebildet, daß beim Abrollen über die Schwenkachse 20 hinweg die Ausnehmung 13 bzw. deren Füllung durch das Materialelement 25 keine elastische federnde Wirkung ausübt, sondern praktisch kraftlos bis zum Anschlag nachgibt, bei der der Sohlenbelag 11 an einem harten, unnachgiebigen Bereich des Schuhs 1 zur Anlage kommt.So in the present invention, the effect the recess 13 formed such that when Roll off over the pivot axis 20 Recess 13 or their filling by Material element 25 no elastic resilient effect exercises, but practically without power up to the stop yields, in which the sole covering 11 on a hard, uncompromising area of the shoe 1 comes to rest.

Der Schuh 1 gemäß einer der vorstehend beschriebenen vier Ausführungsformen zeichnet sich dadurch aus, daß beim Laufen automatisch ein Abrollen des Schuhs 1 bzw. des Fußes auf dem Untergrund bewirkt wird. Dies wird durch die keilförmige Ausnehmung 13 zwischen dem Sohlenkörper 10 und dem Sohlenbelag 11 bewerkstelligt, denn der Sohlenbelag 11 weicht mit seinem Schwenkelement 18 bei einer Belastung im Fersenbereich 6 nach oben aus, und es bildet sich weich einfedernd ein stumpfer Winkel an der Sohle 2 aus, dessen Spitze im Bereich der Schwenkachse 20 angeordnet ist.The shoe 1 according to one of those described above four embodiments are characterized in that when running, the shoe automatically rolls off 1 or the foot is caused on the ground. This is through the wedge-shaped recess 13 between the Sole body 10 and the sole covering 11 accomplished, because the sole covering 11 also gives way its pivoting element 18 when loaded in Heel area 6 upwards and it forms softly deflecting an obtuse angle on the sole 2 whose tip is in the area of the pivot axis 20 is arranged.

Um diesen stumpfen Winkel kippt der Schuh 1 nach vorne ab, wodurch das Knie des Läufers gebeugt wird und die Stoßbelastung vom Läufer bei gebeugtem Knie aufgenommen wird. Die Stoßbelastung wird nicht auf die empfindlichen Gelenke und auf die Wirbelsäule übertragen, sondern vom Skelett und von den entsprechenden Muskeln aufgenommen.The shoe 1 tilts about this obtuse angle from the front, causing the runner's knee to bend and the impact load from the runner with the knee bent is recorded. The shock load is not on the sensitive joints and on the spine transmitted, but from the skeleton and from the corresponding muscles absorbed.

Die Erfindung ist nicht auf die vorstehend erläuterten vier Ausführungsformen beschränkt; der Fachmann kann ohne weiteres weitere Abwandlungen der Erfindung auffinden. Beispielsweise liegt im Rahmen der Erfindung auch eine Ausführungsform, bei der der Sohlenkörper 10 und der Sohlenbelag 11 einteilig und/oder einstückig ausgebildet sind.The invention is not based on the above explained four embodiments limited; the Those skilled in the art can readily make further modifications to the Find invention. For example, is in the frame the invention also an embodiment in which the Sole body 10 and the sole covering 11 in one piece and / or are formed in one piece.
