Abstract

The shoe sole has a torsion unit (220), which decouples a front area of the show sole with regard to a rolling motion line from a rear shoe sole area. The front shoe sole area and the rear shoe sole area are adhesively formed in a single piece, and have a clearly tapering width in an area of the torsion unit. The front shoe sole area and the rear shoe sole area stands in connection with one another by a base. An independent claim is also included for a shoe e.g. running show, with a shoe sole.

Description

Die vorliegende Erfindung bezieht sich auf eine Schuhsohle, insbesondere geeignet für Laufschuhe, gemäß der Schutzansprüche 1 und 30.The present invention relates to a shoe sole, in particular suitable for running shoes, according to the protection claims 1 and 30.

Beim Einsatz von Schuhen, insbesondere beim Gebrauch von Schuhen für die Ausübung von verschiedenen Sportarten und insbesondere bei Laufschuhen, hat es sich schon in der Vergangenheit als vorteilhaft erwiesen, durch die Ausgestaltung der Schuhsohle des Schuhs das Abrollen des Fußes zu unterstützen.In the use of shoes, especially in the use of shoes for the exercise of various sports and in particular running shoes, it has been proven in the past to assist by the design of the shoe sole of the shoe, the rolling of the foot.

Um diesem Abrollen des Fußes entgegen zu kommen, sind in der heutigen Schuhtechnologie Schuhsohlen bekannt, die im Bereich des Mittelfußes der Schuhsohle ein Torsionselement aufweisen, das eine Verwringung oder auch Verdrehung des Vorderfußsohlenbereiches relativ zum Hinterfußsohlenbereich im Bereich des Mittelfußes ermöglicht. Damit soll eine Anpassung der Schuhsohle an den Untergrund und die Unterstützung des Abrollens des Fußes ermöglicht werden.In order to counteract this rolling of the foot, shoe soles are known in today's footwear technology, which have a torsion element in the region of the midfoot of the shoe sole, which enables a Verwringung or twisting of the forefoot area relative to the Hinterfußsohlenbereich in the region of the metatarsus. This is to allow adaptation of the shoe sole to the ground and the support of the unrolling of the foot.

Ein Schuhsohle nach diesem Stand der Technik ist in der Figur 1 gezeigt. Die Figur 1 zeigt eine Schuhsohle nach dem bekannten Stand der Technik aus einer Draufsicht. Zu erkennen ist die Schuhsohle 10, die durch das Torsionselement 20 in die Schuhsohlenbereiche 25 (Vorderfußbereich) und 30 (Hinterfußbereich) aufgeteilt wird. Durch das Torsionselement 20 werden somit der Vorderfußbereich 25 der Schuhsohle und der Hinterfußbereich 30 der Schuhsohle bezüglich ihrer Abrolllinien so entkoppelt, dass, wie in Figur 1 angedeutet, diese beiden Schuhsohlenbereiche 25 und 30sich im Mittelfußbereich gegeneinander verwringen, bzw. verdrehen können.A shoe sole according to this prior art is in the FIG. 1 shown. The FIG. 1 shows a shoe sole according to the known prior art from a plan view. Evident is the shoe sole 10, which is divided by the torsion member 20 in the shoe sole areas 25 (forefoot area) and 30 (rear foot area). Thus, the forefoot portion 25 of the shoe sole and the rearfoot portion 30 of the shoe sole are decoupled with respect to their rolling lines by the torsion element 20 so that, as in FIG. 1 indicated, these two shoe sole areas 25 and 30want to each other in the metatarsal area, or can twist.

Bei Schuhsohlen gemäß dem Stand der Technik wird jedoch nicht beachtet, dass der menschliche Fuß ein sogenanntes Multi Joint System ist. Dieses ermöglicht eine optimale Adaption des Fußes an Bodenunebenheiten und Schräglagen im Barfußgang. Obwohl die Abrolllinie des Fußes je nach Art des Ganges und insbesondere je nach z.B. ausgeübter Sportart variieren kann, handelt es sich doch in der Regel um einen nahezu s-förmigen Verlauf: Der erste Auftreffpunkt beim Abrollen des Fußes ist der äußere Fußrand. Durch die Gewichtsverlagerung in der Standphase geht der Belastungsverlauf nach vorne innen über das Längsgewölbe, um in der Abstoßphase über die Großzehe ausgeleitet zu werden. Bei unterschiedlichen Arten des Ganges und insbesondre bei unterschiedlichen Sportarten kann diese s-förmige Abrolllinie unter Umständen flacher verlaufen, sodass der Auftreffpunkt mehr in der Mitte liegt und auch der Abstoßpunkt eher mittig im Bereich des Vorderfusses zu finden ist.In the case of prior art shoe soles, however, it is not considered that the human foot is a so-called multi-joint system. This allows an optimal adaptation of the foot to bumps and slopes in barefoot gear. Although the rolling line of the foot may vary depending on the type of the gait and in particular depending on the type of sport practiced, it is usually a nearly s-shaped course: The first impact point when rolling the foot is the outer edge of the foot. Due to the shift in weight in the stance phase, the course of the load goes forward inwards over the longitudinal arch, in order to be discharged via the big toe during the repulsion phase. In different types of gear and insbesondre in different sports, this s-shaped rolling line may be flatter under certain circumstances, so that the point of impact is located more in the middle and also the kick point is more centrally located in the area of the forefoot.

Aufgrund dieser biomechanischen Funktionsweise des menschlichen Fußes werden Schuhsohlen nach dem Stand der Technik als nicht optimal empfunden, da diese nur eine Verdrehung um eine gerade Achse insbesondere eine Verdrehung des gesamten Vorderfussbereiches relativ zum Hinterfußbereich um genau einen Punkt, nämlich den Mittelfußbereich, erlauben. Dies stellt der oben ausgeführten natürlichen, s-förmigen Abrollbewegung des menschlichen Fußes Widerstände entgegen, da der Fuß aufgrund seiner natürlichen Bewegung beim Abrollen gegen die jeweils steifen Vorder- und Hinterfußsohlenbereiche arbeiten muss. Dies führt zu einem unnötigen Aufwand zusätzlicher Kräfte und insbesondere zu einer nicht optimalen Abrollbewegung, die schädliche Folgen auf die beteiligten Gelenke haben kann. Daher ist im Gegenteil eine Unterstützung der s-förmigen Abrolllinie des Fußes gewünscht.Due to this biomechanical mode of operation of the human foot, shoe soles according to the prior art are perceived as not optimal because they allow only a rotation about a straight axis, in particular a rotation of the entire forefoot area relative to the hindfoot area by exactly one point, namely the midfoot area. This counteracts the above-mentioned natural, sigmoidal rolling motion of the human foot, since the foot, due to its natural motion when rolling, must work against the respectively stiff front and rear sole areas. This leads to an unnecessary expenditure of additional forces and in particular to a non-optimal rolling motion, which can have harmful consequences on the joints involved. Therefore, on the contrary, a support of the s-shaped rolling line of the foot is desired.

US4922631 A offenbart eine Schuhsohle, deren Schaft durch ein Versteifungselement gegen Durchbiegung in beide Richtungen über erste und zweite Achsen quer zur Längsachse des Schuhs versteift ist, wobei der Schuh eine relative Verdrehung des vorderen und des hinteren Sohlenteils zulässt. US4922631 A discloses a shoe sole whose upper is stiffened by a stiffening element against deflection in both directions via first and second axes transverse to the longitudinal axis of the shoe, the shoe allowing relative rotation of the front and rear sole parts.

Es ist daher die Aufgabe der vorliegenden Erfindung, ein Schuhsohle zur Verfügung zu stellen, die dahingehend optimiert ist, das s-förmige Abrollverhalten des menschlichen Fußes zu unterstützen.It is therefore the object of the present invention to provide a shoe sole which is optimized to support the s-shaped rolling behavior of the human foot.

Diese Aufgabe wird durch den Gegenstand der unabhängigen Patentansprüche gelöst. Bevorzugte Ausführungsformen sind Gegenstand der Unteransprüche.This object is solved by the subject matter of the independent patent claims. Preferred embodiments are subject of the dependent claims.

Der vorliegenden Erfindung liegt somit die Erkenntnis zugrunde, dass Schuhsohlen häufig als nicht optimiert in Bezug auf die Unterstützung des natürlichen biomechanisch s-förmig verlaufenden Abrollens des menschlichen Fußes angesehen werden, da bekannte Schuhsohlen nur ein Verwringen des gesamten Vorderfußes gegenüber dem gesamten Hinterfuß ermöglichen.The present invention is thus based on the finding that shoe soles are often regarded as not optimized with respect to the support of the natural biomechanically S-shaped rolling of the human foot, as known Shoe soles only allow a wringing of the entire forefoot against the entire hind foot.

Gemäß der vorliegenden Erfindung wird daher eine Schuhsohle zur Verfügung gestellt, die ein s-förmiges Abrollen des menschlichen Fußes ähnlich der natürlichen biomechanischen Funktionsweise des Fußes gewährleistet. Dieses wird dadurch erreicht, dass die Schuhsohle ein Torsionselement beinhaltet, welches die Schuhsohle in mehrere Schuhsohlenbereiche aufteilt und einen vorderen Bereich der Schuhsohle bezüglich der Abrolllinie von einem hinteren Schuhsohlenbereich entkoppelt, wobei die Schuhsohle dadurch gekennzeichnet ist, dass ein vordere und hintere Schuhsohlenbereich einstückig, d.h. zusammenhängend ausgebildet ist und dabei im Bereich des Torsionselements eine deutlich verjüngte Breite aufweist. Somit wird ein im Wesentlichen durchgängig s-förmig vom äußeren Hinterfußbereich der Schuhsohle zum inneren Vorderfußbereich der Schuhsohle verlaufender Schuhsohlenbereich abgeteilt, welcher die s-förmige Abrolllinie des Fußes unterstützt.Therefore, according to the present invention, there is provided a shoe sole which ensures an S-shaped unrolling of the human foot similar to the natural biomechanical operation of the foot. This is achieved in that the shoe sole includes a torsion element which divides the shoe sole into a plurality of shoe sole regions and decouples a front region of the shoe sole with respect to the rolling line from a rear shoe sole region, wherein the shoe sole is characterized in that a front and rear shoe sole region in one piece, i. is formed contiguous and thereby has a significantly narrowed width in the region of the torsion element. Thus, a substantially continuous S-shaped sole extending from the outer rear foot region of the shoe sole to the inner forefoot region of the shoe sole area is divided, which supports the s-shaped rolling line of the foot.

In einer bevorzugten Ausführungsform ist die Schuhsohle so ausgeführt, dass der vordere und hintere Schuhsohlenbereich durch einen Steg miteinander in Verbindung steht. Weiterhin verläuft der Steg bevorzugterweise diagonal und verbindet insbesondere den hinteren Außenfußbereich der Schuhsohle mit dem vorderen Innenfußbereich. Bevorzugterweise ist die Schuhsohle weiterhin so ausgeführt, dass der Steg zusammen mit den angrenzenden Teilen des vorderen Schuhsohlenbereichs und hinteren Schuhsohlenbereichs eine S-Kurve beschreibt.In a preferred embodiment, the shoe sole is designed so that the front and rear shoe sole region is connected to each other by a web. Furthermore, the web preferably extends diagonally and in particular connects the rear outer foot region of the shoe sole with the front inner foot region. Preferably, the shoe sole is further configured such that the web describes an S-curve together with the adjacent parts of the front shoe sole region and rear shoe sole region.

In einer weiteren bevorzugten Ausführungsform ist das Torsionselement im Wesentlichen in der Schuhsohlenmitte vorgesehen und im Wesentlichen zweistückig ausgebildet, ein erstes Stück an der Fußaußenseite und ein zweites Stück an der Fußinnenseite. Bevorzugterweise ist das Torsionselement so ausgeführt, dass das Torsionselementstück an der Fußaußenseite sich nach vorne in den vorderen Schuhsohlenbereich erstreckt und dass Torsionselementstück im Innenfußbereich sich nach hinten in den hinteren Bereich der Schuhsohle erstreckt. Weiterhin erfolgt die Erstreckung in einer bevorzugten Ausführungsform jeweils sichelförmig, insbesondere dadurch, dass das Torsionselement im Innenfußbereich sich nach vorne in die Mitte des vorderen Schuhsohlenbereiches erstreckt und dann wieder an den äußeren Schuhsohlenaußenrand verläuft und das Torsionselement im Außenfußbereich sich nach hinten in die Mitte des hinteren Schuhsohlenstücks erstreckt und dann wieder an den inneren Schuhsohlenrand verläuft.In a further preferred embodiment, the torsion element is provided substantially in the middle of the shoe sole and formed substantially in two pieces, a first piece on the foot outside and a second piece on the inside of the foot. Preferably, the torsion element is designed so that the Torsionselementstück on the foot outside extends forward into the front shoe sole region and that Torsionselementstück in Innenfußbereich extends backwards into the rear of the shoe sole. Furthermore, in a preferred embodiment, the extension is in each case sickle-shaped, in particular in that the torsion element in the inner foot region extends forwards into the center of the front shoe sole region and then extends again to the outer sole of the shoe sole and the torsion element in the outer foot region extends rearwardly to the center of the rear shoe sole piece and then back to the inner sole of the shoe sole.

In einer bevorzugten Ausführungsform weist das Torsionselement weiterhin stabförmige Stücke und der Verbindungssteg der Schuhsohle stabförmige Aussparungen auf, wobei die stabförmigen Stücke die stabförmigen Aussparungen im Wesentlichen ausfüllen. In einer anderen bevorzugten Ausführungsform ist das Torsionselement in der Schuhsohlenmitte im wesentlichen flächig über die Schuhsohlenbreite ausgeführt und zwischen der Schuhsohle und einem Schuh, der mit einer Schuhsohle gemäß der vorliegenden Erfindung ausgestattet ist, angeordnet.In a preferred embodiment, the torsion element further comprises rod-shaped pieces and the connecting web of the shoe sole rod-shaped recesses, wherein the rod-shaped pieces fill the rod-shaped recesses substantially. In another preferred embodiment, the torsion element in the center of the shoe sole is substantially flat over the width of the shoe sole and is arranged between the shoe sole and a shoe equipped with a shoe sole according to the present invention.

Des weiteren ist das Torsionselement bevorzugterweise so ausgeführt ist, dass es im wesentlichen bis zum äußeren Schuhsohlenrand reicht. In einer weiteren bevorzugten Ausführungsform ist mindestens eines der Torsionselementstücke so ausgeführt, dass es nicht bis zum äußeren Rand der Schuhsohle reicht und die Schuhsohle eine Kerbe aufweist, die von dem Punkt an, wo das Torsionselementstück endet, den sichelförmigen Verlauf des Torsionselementstückes bis zum Schuhsohlenrand fortführt.Furthermore, the torsion element is preferably designed so that it extends substantially to the outer sole of the shoe sole. In a further preferred embodiment, at least one of the Torsionselementstücke is designed so that it does not extend to the outer edge of the shoe sole and the shoe sole has a notch, which continues from the point where the Torsionselementstück ends, the crescent shape of the Torsionselementstückes to the shoe sole edge ,

In einem weiteren Aspekt der vorliegenden Erfindung wird die Aufgabe weiterhin gelöst durch eine Schuhsohle welche eine Torsionselement enthält, wobei das Torsionselement die Schuhsohle in mehrere Schuhsohlenbereiche aufteilt, so dass die mehreren Schuhsohlenbereiche bezüglich ihrer Abrolllinien voneinander entkoppelt sind. Das Torsionselement ist dabei in der Schuhsohlenmitte vorgesehen und so ausgeführt, dass mindestens einer der Schuhsohlenbereiche eine, vom äußeren Hinterfußbereich der Schuhsohle zum inneren Vorderfußbereich der Schuhsohle im Wesentlichen durchgehend verlaufende, s-förmige Form hat.In a further aspect of the present invention, the object is further achieved by a shoe sole which contains a torsion element, wherein the torsion element divides the shoe sole into a plurality of shoe sole regions, so that the several shoe sole regions are decoupled from one another with respect to their rolling lines. The torsion element is provided in the center of the shoe sole and designed so that at least one of the shoe sole regions has a, from the outer Hinterfußbereich the shoe sole to the inner forefoot of the shoe sole substantially continuously extending, S-shaped form.

In einem weiteren Aspekt der vorliegenden Erfindung wird die Aufgabe weiterhin gelöst durch eine Schuhsohle welche ein Torsionselement enthält, das so ausgeführt ist, dass die Schuhsohle durch das Torsionselement in mehrere Schuhsohlenbereiche aufgeteilt wird, wobei zumindest einer dieser Schuhsohlenbereiche eine, vom äußeren Hinterfußbereich zum inneren Vorderfußbereich im Wesentlichen durchgängig verlaufende, s-förmige Form aufweist.In a further aspect of the present invention, the object is further achieved by a shoe sole which includes a torsion element which is designed so that the shoe sole is divided by the torsion element into a plurality of shoe sole regions, wherein at least one of these shoe sole regions, one from the outer rear foot region to the inner forefoot area has substantially continuous, s-shaped form.

Darüber hinaus ist das Torsionselement bevorzugterweise so ausgeführt, dass das Torsionselement im wesentlichen zweistückig ausgebildet ist, ein erstes Stück an der Fußinnenseite und ein zweites Stück an der Fußaußenseite, wobei das erste Stück vom inneren Mittelfußbereich ausgehend sichelförmig über den mittleren Bereich des inneren Hinterfußbereiches zum inneren Sohlenrand verläuft und das zweite Stück vom äußeren Mittelfußbereich ausgehend sichelförmig über den mittleren Bereich des äußeren Vorderfußbereiches zum äußeren Sohlenrand verläuft. Dabei wird die Schuhsohle bevorzugterweise in mindestens drei Torsionselementstücke aufgeteilt, wobei bevorzugterweise neben dem mindestens einen s-förmigen Schuhsohlenbereich mindestens zwei weitere Schuhsohlenbereiche eine im Wesentlichen elliptische Form aufweisen und einer dieser mindestens zwei elliptischen Schuhsohlenbereiche im inneren Hinterfußbereich angeordnet ist und ein weiterer dieser mindestens zwei elliptischen Schuhsohlenbereiche im äußeren Vorderfußbereich angeordnet ist.In addition, the torsion element is preferably designed so that the torsion element is formed substantially in two pieces, a first piece on the inside of the foot and a second piece on the outside of the foot, the first piece from the inner metatarsal area starting sickle-shaped over the middle region of the inner Hinterfußbereiches to the inner Sole edge runs and the second piece extending from the outer metatarsal area starting sickle-shaped over the middle region of the outer Vorderfußbereiches to the outer sole edge. In this case, the shoe sole is preferably divided into at least three torsion element pieces, wherein preferably at least two further shoe sole areas have a substantially elliptical shape in addition to the at least one s-shaped sole area and one of these at least two elliptical shoe sole areas in the inner Hinterfußbereich is arranged and another of these at least two elliptical Shoe sole areas is arranged in the outer forefoot area.

Im Folgenden werden bevorzugte Ausführungsformen der vorliegenden Erfindung unter Bezugnahme auf die beiliegenden Zeichnungen näher erläutert. Dabei zeigen die Zeichnungen im Einzelnen:

  • Figur 1 eine Ausführungsform einer Schuhsohle nach dem Stand der Technik in einer Draufsicht,
  • Figur 2 eine bevorzugte Ausführungsform einer Schuhsohle gemäß der vorliegenden Erfindung in einer Draufsicht,
  • Figur 3 eine bevorzugte Ausführungsform einer Schuhsohle gemäß der vorliegenden Erfindung in einer Schnittansicht des Mittelfußbereiches;
  • Figur 4 eine bevorzugte Ausführungsform einer Schuhsohle gemäß der vorliegenden Erfindung in einer Schnittansicht des Vorderfußbereiches.
  • Figur 5 eine weitere bevorzugte Ausführungsform einer Schuhsohle gemäß der vorliegenden Erfindung in einer Draufsicht; und

Hereinafter, preferred embodiments of the present invention will be explained in more detail with reference to the accompanying drawings. The drawings show in detail:
  • FIG. 1 an embodiment of a shoe sole according to the prior art in a plan view,
  • FIG. 2 A preferred embodiment of a shoe sole according to the present invention in a plan view,
  • FIG. 3 a preferred embodiment of a shoe sole according to the present invention in a sectional view of the midfoot region;
  • FIG. 4 a preferred embodiment of a shoe sole according to the present invention in a sectional view of the forefoot area.
  • FIG. 5 a further preferred embodiment of a shoe sole according to the present invention in a plan view; and
  • FIG. 6 the further preferred embodiment of a shoe sole Fig. 5 in a sectional view of the midfoot area.

Figur 1 zeigt eine Ausführungsform einer Schuhsohle 5, die nach dem Stand der Technik bekannt ist. Klar erkennbar zeigt die Figur 1 die Schuhsohle 10, die durch das Torsionselement 20 in die Schuhsohlenbereiche 25 und 30 eingeteilt wird. Wie in Figur 1 angedeutet, können sich dadurch der Vorderfußbereich, d.h. der Schuhsohlenbereich 25 und der Hinterfußbereich, d.h. der Schuhsohlenbereich 30 gegeneinander verwringen. Dem Torsionselement 20 kommt somit in einer Schuhsohle 5 nach dem Stand der Technik eine gelenkartige Funktion zu. Nachteilig ist jedoch, dass beim Abrollen eines solchen Schuhsohle keine s-förmige Abrolllinie unterstützt wird sondern im Gegenteil Widerstände gegen ein solches s-förmiges abrollen des Fußes aufgebaut werden. FIG. 1 shows an embodiment of a shoe sole 5, which is known in the prior art. Clearly recognizable the shows FIG. 1 the shoe sole 10, which is divided by the torsion 20 in the shoe sole areas 25 and 30. As in FIG. 1 indicated thereby, the forefoot area, ie, the shoe sole area 25 and the rear foot area, ie, the shoe sole area 30 can be entangled against each other. The torsion element 20 thus comes in a shoe sole 5 according to the prior art to a joint-like function. The disadvantage, however, is that when rolling such a shoe sole no s-shaped rolling line is supported but on the contrary resistors against such an s-shaped rolling of the foot are built.

Figur 2 zeigt eine bevorzugte Ausführungsform eine Schuhsohle 200 gemäß der vorliegenden Erfindung. Klar erkennbar aus der Figur 2 ist die Schuhsohle 210, die durch das Torsionselement 220 in die drei Schuhsohlenbereiche 215, 234 und 238 aufgeteilt wird. Erkennbar ist des weiteren, dass die Schuhsohle 210 einstückig, d.h. zusammenhängend ausgebildet ist. Im Bereich des Torsionselementes 220 weist die Schuhsohle 210 darüber hinaus eine deutlich verjüngte Breite 215 auf. Um die Schuhsohle 210 in diese drei Schuhsohlenbereiche 215, 234, 238 aufzuteilen, weist das Torsionselement 220 insbesondere die Torsionselementstücke 224 und 228 auf. In einer bevorzugten Ausführungsform sind die Torsionselementstücke 224 und 228 stegförmig ausgeführt. In einer bevorzugten Ausführungsform ist im Mittelfußbereich das Torsionselement 220 flächig umfassend über die Breite der Schuhsohle 210 ausgeführt. Das heißt, das Torsionselement 220 erstreckt sich im Mittelfußbereich bevorzugterweise über die gesamte Breite der Schuhsohle 210. Wie später mit Bezug auf Figur 3 näher ausgeführt, ist bevorzugterweise die Schuhsohle 210 im Mittelfußbereich so ausgeführt, dass, wie in Figur 2 zu erkennen, zumindest in einem Teil des Mittelfußbereiches das Torsionselement 220 unter der Schuhsohle 210 angeordnet ist, so dass die Schuhsohle 210 eine sich über den Mittelfußbereich erstreckende, durch den Verbindungssteg 215 ausgestaltete, durchgängige Form aufweisen kann. Dieser Verbindungssteg 215, der den vorderen und hinteren Schuhsohlenbereich verbindet, verläuft im mittleren Schuhsohlenbereich diagonal zwischen den Torsionselementstücken 224 und 228. FIG. 2 a preferred embodiment shows a shoe sole 200 according to the present invention. Clearly recognizable from the FIG. 2 is the shoe sole 210, which is divided by the torsion element 220 into the three shoe sole regions 215, 234 and 238. It can be seen further that the shoe sole 210 is formed in one piece, ie integrally. In the region of the torsion element 220, the shoe sole 210 also has a significantly narrowed width 215. In order to divide the shoe sole 210 into these three shoe sole regions 215, 234, 238, the torsion element 220 has, in particular, the torsion element pieces 224 and 228. In a preferred embodiment, the Torsionselementstücke 224 and 228 are designed web-shaped. In a preferred embodiment, in the metatarsal region, the torsion element 220 is configured in a comprehensive manner over the width of the shoe sole 210. That is, the torsion member 220 extends in the midfoot region preferably over the entire width of the shoe sole 210. As later with reference to FIG FIG. 3 1, the shoe sole 210 in the midfoot region is preferably designed such that, as in FIG FIG. 2 to recognize, at least in a part of the midfoot region, the torsion element 220 is disposed under the shoe sole 210, so that the shoe sole 210 is a about may have the metatarsal region, formed by the connecting web 215, continuous shape. This connecting web 215, which connects the front and rear shoe sole region, extends diagonally between the Torsionselementstücken 224 and 228 in the middle shoe sole region.

Die Torsionselementstücke 224, 228 sind des Weiteren so ausgeführt, dass ein Torsionselementstück, im Speziellen das Torsionselementstück 224 an der Fußaußenseite sich nach vorne in den vorderen Schuhsohlenbereich erstreckt und dass Torsionselementstück 228 im Innenfußbereich sich nach hinten in den hinteren Bereich der Schuhsohle erstreckt. Weiterhin erfolgt diese Erstreckung in einer bevorzugten Ausführungsform jeweils sichelförmig, insbesondere dadurch, dass das Torsionselement 224 sich nach vorne in die Mitte des vorderen Schuhsohlenbereiches erstreckt und dann wieder an den äußeren Schuhsohlenaußenrand verläuft und das Torsionselement 228 sich nach hinten in die Mitte des hinteren Schuhsohlenstücks erstreckt und dann wieder an den inneren Schuhsohlenrand verläuft. In einer bevorzugten Ausführungsform verläuft das Torsionselementstück 224 vom äußeren Mittelfußbereich ausgehend sichelförmig über den äußeren Vorderfußbereich. Wie aus Figur 2 erkennbar, weist somit das Torsionselementstück 224 des Torsionselements 220 eine bogen- oder sichelform auf, die vom Schuhsohlenbereich 215 den Schuhsohlenbereich 234 abteilt, der am äußeren Vorderfuß angeordnet ist. Des Weiteren ist der Torsionselementstück 228 des Torsionselements 220 so ausgeführt, dass er vom inneren Mittelfuß ausgehend bogenförmig über den inneren Hinterfußbereich verläuft. Damit weist der Torsionselementstück 228 eine im Wesentlichen bogen- oder sichelförmige Form auf, die vom Schuhsohlenbereich 215 den Schuhsohlenbereich 238 abteilt, der am inneren Hinterfußbereich angeordnet ist. Bevorzugterweise weisen die Schuhsohlenbereiche 234, 238 eine im Wesentlichen elliptische Form auf. Diese Form wird begrenzt durch den äußeren Rand der Schuhsohle 210 auf der einen Seite und die bogen- oder sichelförmigen stegförmig ausgeführten Torsionselementstücke 224, 228 auf der anderen Seite. Dadurch wird erreicht, dass der Schuhsohlenbereich 215 der Schuhsohle 210 eine vom äußeren Hinterfuß zum inneren Vorderfuß im Wesentlichen durchgehend verlaufende s-Form aufweist. Diese s-Form ist dahingehend vorteilhaft, dass beim Aufsetzen des Fußes mittels eines Schuhs, der eine erfindungsgemäße Schuhsohle 210 aufweist, von der Ferse, also dem Hinterfußbereich beginnend, eine s-förmige Abrolllinie des Fußes, wie sie dem biodynamisch natürlichen Abrollverhalten des Fußes entspricht, durch den im Wesentlichen s-förmig gestalteten Schuhsohlenbereich 215 unterstützt, bzw. gewährleistet wird.The torsion element pieces 224, 228 are further configured such that a torsion element piece, in particular the torsion element piece 224 on the outside of the foot extends forwards into the front shoe sole region and that torsion element piece 228 in the inner foot region extends rearwardly into the rear region of the shoe sole. Furthermore, in a preferred embodiment, this extension is in each case sickle-shaped, in particular in that the torsion element 224 extends forwards into the center of the front shoe sole region and then again extends to the outer sole of the shoe sole and the torsion element 228 extends rearwardly into the center of the rear shoe sole piece and then go back to the inner sole of the shoe sole. In a preferred embodiment, the torsion element piece 224 extends crescent-shaped from the outer metatarsal area over the outer forefoot area. How out FIG. 2 As can be seen, the torsion element piece 224 of the torsion element 220 thus has an arcuate or sickle shape which divides the shoe sole region 234 from the shoe sole region 215, which is arranged on the outer forefoot. Further, the torsion member 228 of the torsion member 220 is configured to extend arcuately from the inner metatarsus via the inner hindfoot region. Thus, the torsion element piece 228 has a substantially arcuate or sickle-shaped shape which separates the shoe sole region 238 from the shoe sole region 215, which is arranged on the inner rear foot region. Preferably, the shoe sole regions 234, 238 have a substantially elliptical shape. This shape is limited by the outer edge of the shoe sole 210 on one side and the arcuate or crescent-shaped web-shaped Torsionselementstücke 224, 228 on the other side. It is thereby achieved that the shoe sole region 215 of the shoe sole 210 has an essentially continuous s-shape running from the outer rear foot to the inner forefoot. This s-shape is advantageous in that when placing the foot by means of a shoe having a shoe sole 210 according to the invention, starting from the heel, so the hindfoot, an S-shaped rolling line of the foot, as they are the biodynamic natural Rolling behavior of the foot corresponds, supported by the substantially s-shaped shoe sole region 215, or is guaranteed.

Figur 3 zeigt eine Schnittansicht (entsprechend der Schnittlinie III in Figur 2) eines Sportschuhs 300 mit einer Schuhsohle 310, die eine dämpfende Zwischensohle 312, eine Schuhsohle 314 und ein Torsionselement 316 enthält. Der hier in Figur 3 gezeigte Schnitt verläuft durch den Mittelfußbereich (vgl. Schnittlinie III in Figur 2) der bereits oben mit Bezug auf Figur 2 diskutierten Ausführungsform einer Schuhsohle 200 bzw. 300. Wie aus Figur 3 zu erkennen, ist das Torsionselement 316 im Mittelfußbereich so ausgeführt, dass es zumindest teilweise unter der Schuhsohle 314 und somit zumindest teilweise zwischen der Schuhsohle 314 und der Zwischensohle 312 liegt. Wie bereits oben ausgeführt, wird dadurch gewährleistet, dass die Schuhsohle 314 im Mittelfußbereich einen durchgehenden Bereich, insbesondere den Verbindungssteg 215, aufweisen kann. FIG. 3 shows a sectional view (corresponding to the section line III in FIG FIG. 2 ) of a sports shoe 300 having a shoe sole 310 that includes a cushioning midsole 312, a shoe sole 314, and a torsion member 316. The one in here FIG. 3 Section shown extends through the midfoot area (see section line III in FIG. 2 ) which has already been referred to above FIG. 2 discussed embodiment of a shoe sole 200 and 300th As from FIG. 3 The torsion element 316 in the midfoot region is designed such that it lies at least partially under the shoe sole 314 and thus at least partially between the shoe sole 314 and the midsole 312. As already stated above, this ensures that the shoe sole 314 in the midfoot region can have a continuous region, in particular the connecting web 215.

Figur 4 zeigt eine Schnittansicht (entsprechend der Schnittlinie IV in Figur 2) eines Sportschuhs 400, der ein erfindungsgemäßes Schuhsohle 410 aufweist. Der Schnitt, der in Figur 4 gezeigt ist, läuft durch den Hinterfußbereich des Schuhs 400 (vgl. Schnittlinie IV in Figur 2). Wie aus Figur 4 zu erkennen ist, umfasst die erfindungsgemäße Schuhsohle eine Zwischensohle 412, eine Schuhsohle 414 und ein Torsionselement 416. Wie aus Figur 4 erkennbar, ist im Hinterfußbereich das Torsionselement 416 stegförmig ausgeführt. FIG. 4 shows a sectional view (corresponding to the section line IV in FIG FIG. 2 ) of a sports shoe 400 having a shoe sole 410 according to the invention. The cut in FIG. 4 is shown passing through the rear foot region of the shoe 400 (see section line IV in FIG FIG. 2 ). How out FIG. 4 can be seen, the shoe sole according to the invention comprises a midsole 412, a shoe sole 414 and a torsion 416. As out FIG. 4 recognizable, the torsion element 416 is designed web-shaped in the hindfoot region.

Abhängig von der Sportart, die mit Hilfe des Schuhs 400 ausgeführt werden soll, kann in einer anderen, spätere mit Bezug auf Figur 5 ausführlicher diskutierten Ausführungsform das Torsionselement 416 auch so ausgeführt sein, dass die oben mit Bezug auf Figur 2 diskutierten Torsionselementstücke 224, 228 sich jeweils nicht bis zum äußeren Rand der Schuhsohle 414 erstrecken. In dieser Ausführungsform wird der bogenförmige Verlauf der Torsionselementstücke 224, 228 durch die in Figur 4 gezeigte Kerbe 420 in der Schuhsohle 414 bis zum Sohlenrand fortgeführt. Somit kann in vorteilhafter Weise die Torsionssteifigkeit des Torsionselements 416 unterschiedlich je nach den Anforderungen der jeweiligen Sportart, bzw. des jeweiligen Gebrauchs des Schuhs 400 variiert werden. Konkret, in dem Fall, dass das Torsionselement 416 möglichst steif ausgeführt werden soll, erstreckt sich das stegförmige Torsionselement 416 bogen- oder sichelförmig über den äußeren Vorderfußbereich bis zum Rand der Schuhsohle 410. In dem Fall jedoch, dass die jeweilige Verwendung es vorteilhafter erscheinen lässt, das Torsionselement im Vorderfußbereich entsprechend weniger steif auszuführen, wird das Torsionselement 416 nicht bis zum äußeren Rand der Schuhsohle 410 reichen, sondern der bogenförmige Verlauf wird allein durch die Kerbe 420, die in der Schuhsohle 410 angebracht ist, bis zum Rand der Schuhsohle 410 bogenförmig fortgesetzt.Depending on the sport that is to be performed with the help of the shoe 400, in another, later with respect to FIG. 5 In more detail, the torsion member 416 may be configured to be the same as described above with reference to FIGS FIG. 2 Torsionselementstücke discussed 224, 228 each do not extend to the outer edge of the shoe sole 414. In this embodiment, the arcuate course of the Torsionselementstücke 224, 228 by the in FIG. 4 shown notch 420 in the shoe sole 414 continued to the sole edge. Thus, advantageously, the torsional rigidity of the torsion element 416 can be varied differently depending on the requirements of the respective sport or the respective use of the shoe 400. Specifically, in the case where the torsion member 416 is made as rigid as possible the torso element 416 extends arcuately or crescent-shaped over the outer forefoot area to the edge of the shoe sole 410. In the case, however, that the respective use makes it more advantageous to perform the torsion element corresponding less stiff in the forefoot, the torsion is 416 do not extend to the outer edge of the shoe sole 410, but the arcuate course is continued solely by the notch 420, which is mounted in the shoe sole 410, up to the edge of the shoe sole 410 arcuate.

Fig. 5 zeigt eine weitere Ausführungsform einer erfindungsgemäßen Schuhsohle 500. Die gezeigte Schuhsohle 500 weist ähnlich wie die in Fig. 2 bereits diskutierte Ausführungsform der Schuhsohle 200 die Schuhsohlenbereich 534, 538 und 515 auf. Des Weiteren weist die Schuhsohle 500 ähnlich wie die in Fig. 2 gezeigte Ausführungsform einer Schuhsohle 200 ein Torsionselement 520 mit den Torsionselementstücken 528 und 524 auf. In der in Fig. 5 gezeigten Ausführungsform jedoch weist die Schuhsohle 510 im Bereich des Verbindungssteges 515 die stabförmigen Aussparungen 551 bis 555 auf, die durch entsprechende stabförmige Torsionselementstücke 561 bis 565 des Torsionselements 520 ausgefüllt werden. Die Größe und Anzahl der Aussparungen 551 bis 555 bzw. der Torsionselementstücke 561 bis 565 können je nach Verwendungszweck eines Schuhs, der mit einer erfindungsgemäßen Schuhsohle 500 ausgestattet wird, variiert werden. Dies ist insbesondere vorteilhaft, weil dadurch die Steifigkeit des Verbindungssteges 515 bzw. des Torsionselementes 520 insbesondere im Mittelfußbereich variiert werden kann, um den jeweiligen Anforderungen der speziellen Verwendung gerecht zu werden. Darüber hinaus ist in der hier gezeigten Ausführungsform, wie oben mit Bezug auf Fig. 3 bereits angedeutet, gezeigt, dass die Torsionselementstücke 528 bzw. 524 sich in dieser bevorzugten Ausführungsform nicht bis zum Rand der Schuhsohle 510 erstrecken. Vielmehr ist aus Fig. 5 klar zu erkennen, dass die Schuhsohle 510 angrenzend an den Bereich 534 bzw. angrenzend an den Bereich 538 jeweils eine Kerbe 570 bzw. 575 aufweist, die den sichelförmigen Verlauf des Torsionselementstückes 524 bzw. 528 bis zum jeweiligen Rand der Schuhsohle 510 fortführt. Fig. 5 shows a further embodiment of a shoe sole 500 according to the invention. The shoe sole 500 shown has similar to those in Fig. 2 Shoe sole 200 already discussed embodiment, the shoe sole area 534, 538 and 515 on. Furthermore, the shoe sole 500 is similar to that in FIG Fig. 2 As shown embodiment of a shoe sole 200, a torsion 520 with the Torsionselementstücken 528 and 524 on. In the in Fig. 5 In the embodiment shown, however, the shoe sole 510 has in the region of the connecting web 515 the rod-shaped recesses 551 to 555, which are filled by corresponding rod-shaped torsion element pieces 561 to 565 of the torsion element 520. The size and number of the recesses 551 to 555 and the Torsionselementstücke 561 to 565 can be varied depending on the intended use of a shoe, which is equipped with a shoe sole 500 according to the invention. This is particularly advantageous because it allows the rigidity of the connecting web 515 or of the torsion element 520 in particular in the metatarsal area to be varied in order to meet the respective requirements of the specific use. Moreover, in the embodiment shown here, as above with reference to FIG Fig. 3 already indicated, that the Torsionselementstücke 528 and 524 do not extend to the edge of the shoe sole 510 in this preferred embodiment. Rather, it is off Fig. 5 clearly recognizes that the shoe sole 510 adjacent to the region 534 and adjacent to the region 538 each have a notch 570 and 575, which continues the crescent shape of the Torsionselementstückes 524 and 528 to the respective edge of the shoe sole 510.
