Description

Die vorliegende Erfindung betrifft eine Außensohle, die rutschfeste Eigenschaften aufweist. Die vorliegende Erfindung betrifft ferner einen mit einer erfindungsgemäßen Außensohle ausgerüsteten Schuh.The present invention relates to an outsole that has non-slip properties. The present invention also relates to a shoe equipped with an outsole according to the invention.

Die Außensohle des Schuhs wird auch als Laufsohle bezeichnet. Sie ist der Teil des Schuhs, der direkten Bodenkontakt hat. Häufig kommen bei Außensohlen Kautschukmaterialien, Kunststoffe oder Leder zum Einsatz.The outsole of the shoe is also known as the outsole. It is the part of the shoe that is in direct contact with the ground. Rubber materials, plastics or leather are often used for outsoles.

Um dem Schuhträger Stabilität zu gewährleisten, wird von Schuhen bzw. von Laufsohlen Griffigkeit zum Boden erwartet. Schuhe sollen nicht über den Boden rutschen oder gleiten. Hierzu werden die Laufflächen der Schuhe mit Profilen ausgestattet. Bekannt sind dabei Profilierungen gebildet aus Stollen, Rippen, Rillen und Kerbungen in verschiedensten Formen und Zusammensetzungen. So wird z.B. in der DE 969 455 B eine Profilierung der Schuhsohle oder des Absatzes offenbart, deren Profile unregelmäßig angeordnet sind. Rippen und Rillen erzeugen bei unebenem Untergrund eine hohe Gleitreibung und verhindern somit ein Rutschen. Jedoch wird die Griffigkeit einer solchen Sohle bei glatten Oberflächen stark vermindert oder sogar aufgehoben. Eine solche Sohle ist demnach nicht zufriedenstellend.In order to ensure stability for the shoe wearer, shoes or outsoles are expected to have grip on the ground. Shoes should not slip or slide across the floor. For this purpose, the treads of the shoes are equipped with profiles. Profiles formed from studs, ribs, grooves and indentations in a wide variety of shapes and compositions are known. For example, in the DE 969 455 B a profiling of the shoe sole or the heel is disclosed, the profiles of which are arranged irregularly. Ribs and grooves generate high sliding friction on uneven ground and thus prevent slipping. However, the grip of such a sole is greatly reduced or even eliminated on smooth surfaces. Such a sole is therefore not satisfactory.

Denn von einer Schuhsohle wird erwartet, dass sie auch bei extremen Bedingungen Rutschsicherheit bietet. Während sich ein Stollenprofil besonders für Nassrasen, Schnee- und Eisoberflächen eignet, ist ein geripptes, gerilltes oder ein Profil mit Kerbungen besser für nasse und feste Oberflächen geeignet.Because a shoe sole is expected to offer slip resistance even under extreme conditions. While a lugged tread is best suited to wet grass, snow and ice surfaces, a ribbed, grooved or notched tread is better suited to wet and hard surfaces.

Zumeist bietet die Schuhindustrie jedoch Saisonschuhe an, sodass sich das Problem einer Sohle, die für Starkregen im Sommer und für schnee- und eisbedeckte Flächen im Winter eignet, gar nicht erst stellt. Dies ist jedoch unbefriedigend.In most cases, however, the shoe industry offers seasonal shoes, so that the problem of a sole that is suitable for heavy rain in summer and for snow and ice-covered areas in winter does not even arise. However, this is unsatisfactory.

Die US 2012/0260535 A1 beschreibt eine Sohlenstruktur mit einem Außensohlenelement. Das Außensohlenelement umfasst eine Vielzahl von Haftungselementen, wobei jedes dieser Elemente in einer Aussparung des Außensohlenelements angeordnet ist.The U.S. 2012/0260535 A1 describes a sole structure with an outsole element. The outsole element comprises a plurality of adhesion elements, each of these elements being arranged in a recess of the outsole element.

Die US 2011/0247243 A1 beschreibt eine Sohlenstruktur, die ein erstes Stollensystem aus einem ersten Material und ein zweites Stollensystem aus einem zweiten Material umfasst, wobei das erste Stollensystem ein erstes Stollendesign aufweist und das zweite Stollensystem ein zweites Stollendesign.The US 2011/0247243 A1 describes a sole structure comprising a first cleat system made of a first material and a second cleat system made of a second material, wherein the first cleat system has a first cleat design and the second cleat system has a second cleat design.

Vor diesem Hintergrund ist es Aufgabe der vorliegenden Erfindung, eine verbesserte Außensohle für einen Schuh sowie einen mit einer solchen Außensohle ausgerüsteten Schuh bereitzustellen, bei dem die Sohle verbesserte Anti-Rutsch-Eigenschaften aufweist.Against this background, the object of the present invention is to provide an improved outsole for a shoe and a shoe equipped with such an outsole, in which the sole has improved anti-slip properties.

Diese Aufgabe wird gelöst durch eine Außensohle für einen Schuh mit den Merkmalen des Anspruchs 1.This problem is solved by an outsole for a shoe with the features of claim 1.

Bevorzugte Ausführungsformen finden sich in den Unteransprüchen wieder.Preferred embodiments can be found in the dependent claims.

Die erfindungsgemäße Außensohle umfasst eine zumindest teilweise profilierte Lauffläche, die wenigstens einen ersten Profilbereich und in derselben Ebene zumindest einen davon getrennten zweiten Profilbereich umfasst.The outsole according to the invention comprises an at least partially profiled tread, which comprises at least one first profile area and at least one second profile area separate therefrom in the same plane.

Unter dem Begriff Profilbereich versteht die Erfindung ein flächiges mit Profilierungen versehenes Teilareal der Laufsohle mit definierten Eigenschaften. Dazu gehören beispielsweise die für den Aufbau des Profilbereichs verwendete Shore-Härte, die Anordnung verschiedener Profilbereiche auf der Lauffläche oder deren Erhebung gegenüber benachbarten Profilbereichen. Dabei kann sowohl die Form als auch die Größe eines Profilbereichs entsprechend der Verwendungsanforderung (z.B. Laufschuh, Wanderschuh, Business-Schuh) des Schuhs optimiert sein.The term profile area is understood by the invention to mean a flat sub-area of the outsole provided with profiles and having defined properties. These include, for example, the Shore hardness used for the structure of the profile area, the arrangement of different profile areas on the tread or their elevation compared to neighboring profile areas. Both the shape and the size of a profile area can be optimized according to the usage requirement (e.g. running shoe, hiking shoe, business shoe) of the shoe.

Um die verbesserte Bodenhaftung der Laufsohle zu erzielen, soll zum einen der erste Profilbereich eine höhere Shore-Härte aufweisen als der zweite Profilbereich. Zum anderen soll innerhalb des ersten Profilbereichs wenigstens eine elastische Haftungsschale ausgebildet sein. Schließlich soll der zweite Profilbereich gegenüber der Oberfläche des ersten Profilbereichs nach außen überstehen. Dabei umfasst die Lauffläche vorzugsweise mehrere erste Profilbereiche mit darin angeordneten elastischen Haftungsschalen und davon getrennte zweite Profilbereiche. Vorzugsweise ist die Haftungsschale höckerartig oder noppenartig mit einer umlaufenden Lippe ausgestaltet.In order to achieve the improved traction of the outsole, the first profile area should have a higher shore hardness than the second profile area. On the other hand, at least one elastic adhesion shell should be formed within the first profile area. Finally, the second profile area should protrude outwards relative to the surface of the first profile area. In this case, the tread preferably comprises a plurality of first profile areas with elastic adhesion shells arranged therein and separate second profile areas. The adhesion shell is preferably designed in the manner of a hump or knob-like with a peripheral lip.

Den Haftungsschalen wird bei der vorliegenden Erfindung eine besondere Bedeutung beigemessen, denn diese führen zu einer Verkantung mit der Bodenfläche und damit zu einem verbesserten Halt der Sohle auf den Untergrund. Bevorzugt sind die Haftungsschalen deshalb mit einer umlaufenden Lippe versehen, die sich bei Belastung (d.h. beim Auftreten) zusammendrückt und mit dem Untergrund verkantet. Erfindungsgemäß sind die Haftungsschalen deshalb elastisch ausgebildet, vorzugsweise mit einer Shore-Härte, die in etwa der Shore-Härte des zweiten Profilbereichs entspricht. Die Haftungsschalen dienen somit dem Zweck, die Griffigkeit der Außensohle zum Boden zusätzlich zu erhöhen. Bevorzugt ist dabei, dass jeder erste Profilbereich eine Haftungsschale aufnimmt, um eine gleichmäßige Verteilung der elastischen Haftungsschalen auf der Lauffläche zu realisieren.In the case of the present invention, particular importance is attached to the adhesion shells, because they lead to a canting with the floor surface and thus to an improved grip of the sole on the subsoil. The adhesion shells are therefore preferably provided with a peripheral lip, which compresses under load (ie when walking) and cants with the subsurface. According to the invention, the adhesion shells are therefore designed to be elastic, preferably with a Shore hardness that roughly corresponds to the Shore hardness of the second profile area. The liability shells thus serve the purpose of further increasing the grip of the outsole on the ground. It is preferred that each first profile area accommodates an adhesion shell in order to achieve an even distribution of the elastic adhesion shells on the tread.

Bevorzugte Shore-Härten des ersten Profilbereichs liegen vorzugsweise zwischen 60 und 70 (Shore A). Dabei kommen vorzugsweise thermoplastische Elastomere oder thermoplastische Gummimischungen zum Einsatz. Bevorzugte Shore-Härten des zweiten, elastischeren Profilbereichs liegen vorzugsweise bei 50. Vorzugsweisen weisen die elastischen Haftungsschalen dieselbe Shore-Härte von etwa 50 auf.Preferred Shore hardness of the first profile area is preferably between 60 and 70 (Shore A). In this case, preferably thermoplastic elastomers or thermoplastic rubber mixtures are used. The preferred Shore hardness of the second, more elastic profile area is preferably 50. The elastic adhesion shells preferably have the same Shore hardness of around 50.

Die geringere Shore-Härte des zweiten Profilbereichs dient dem Zweck, dass dieser elastisch genug ist, um sich an die Beschaffenheit des Untergrunds anpassen zu können. Außerdem wird beim Auftreten der zweite Profilbereich soweit zusammengepresst, dass der Niveauunterschied zum ersten Profilbereich vollständig ausgeglichen wird.The lower Shore hardness of the second profile area serves the purpose that it is elastic enough to be able to adapt to the nature of the ground. In addition, when you step on the ground, the second profile area is compressed to such an extent that the difference in level to the first profile area is completely compensated.

Bei einer bevorzugten Ausführungsform ist die Oberfläche des ersten Profilbereichs mit einer Vielzahl von Profilkörpern profiliert, die vorzugsweise einen platonischen Aufbau haben. Platonischer Aufbau bedeutet, dass die Profilkörper polyedrisch sind, also beispielsweise tetraedrisch, hexaedrisch, oktaedrisch, dodekaedrisch oder ikosaedrisch. Die Vielzahl dieser geometrischen Körper, die konvex aus der Oberfläche des ersten Profilbereichs herausragen, ermöglicht vorteilhafte Haft- und Gleitreibungseigenschaften des ersten Profilbereichs.In a preferred embodiment, the surface of the first profile area is profiled with a large number of profile bodies, which preferably have a platonic structure. Platonic structure means that the profile bodies are polyhedral, for example tetrahedral, hexahedral, octahedral, dodecahedral or icosahedral. The large number of these geometric bodies, which protrude convexly from the surface of the first profile area, enables advantageous static and sliding friction properties of the first profile area.

Vorzugsweise weist der zweite Profilbereich eine Vielzahl von quer zur Laufrichtung ausgerichteten Lamellen als Profilierung auf, was die Haftung mit dem Untergrund begünstigt.The second profile area preferably has a multiplicity of lamellae aligned transversely to the running direction as a profiling, which promotes adhesion to the ground.

Um die Sohle kostengünstiger zu produzieren, sind die Haftungsschalen jeweils innerhalb einer Ausnehmung des ersten Profilbereichs angeordnet. Gleichzeitig bieten die Ausnehmungen auch Raum, wenn die Haftungsschalen beim Auftreten komprimiert werden und ihren Durchmesser verändern. Deshalb ist es bevorzugt, dass die Ausnehmung einer Haftungsschale in ihrem Durchmesser größer ist als der Durchmesser der darin ausgebildeten Haftungsschale. Eine oval- bis rundförmige Form hat sich als besonders vorteilhaft herausgestellt.In order to produce the sole more cost-effectively, the adhesion shells are each arranged within a recess in the first profile area. At the same time, the recesses also provide space if the adhesion shells are compressed when they occur and change their diameter. Therefore, it is preferable that the recess of an adhesion cup is larger in diameter than the diameter of the adhesion cup formed therein. An oval to round shape has proven to be particularly advantageous.

Vorzugsweise sind die Haftungsschalen konkav ausgebildet und umfassen jeweils eine von einer Außenlippe umrandete Mulde. Dieser Aufbau ermöglicht den Haftungsschalen, dass sie sich bei glatten Oberflächen ansaugen oder in den Untergrund eingreifen können. Denn wird Gewichtsdruck auf eine Haftungsschale ausgeübt, so wird diese komprimiert und die Lippen werden nach außen gedrückt. Dabei wird Luft aus der Mulde verdrängt, wodurch bei glatten Oberflächen ein leichter Unterdruck mit Saugeigenschaften entsteht, so dass ein schnelles Abgleiten oder Rutschen der Sohle verhindert oder zumindest stark unterdrückt werden kann. Damit ein Anhaften auch an unebenen Bodenoberflächen gelingen kann, greifen die Außenlippen der Haftungsschalen in den Untergrund und verkanten sich im Idealfall.The adhesion shells are preferably concave and each comprise a depression bordered by an outer lip. This structure enables the adhesion shells to suck on smooth surfaces or to engage in the subsoil. Because if weight pressure is applied to a grip shell, it is compressed and the lips are pushed outwards. In the process, air is displaced from the trough, resulting in smooth A slight negative pressure with suction properties is created on the surface, so that rapid slipping or slipping of the sole can be prevented or at least greatly suppressed. So that adhesion can also succeed on uneven floor surfaces, the outer lips of the adhesion shells grip into the subsoil and, ideally, tilt.

Damit die Höhendifferenzen zwischen dem ersten Profilbereich und dem zweiten Profilbereich für den Schuhträger keine Verminderung des Laufkomforts verursachen, ist vorzugsweise vorgesehen, dass die Haftungsschalen in gleichem Maße gegenüber der Oberfläche des ersten Profilbereichs überstehen wie der zweite Profilbereich. Es ist vorzugsweise vorgesehen, dass die Haftungsschalen und/oder die zweiten Profilbereiche elastisch ausgeformt sind, damit sie sich hervorragend an den Untergrund anpassen können ohne dabei den Laufkomfort für den Träger einzuschränken.To ensure that the height differences between the first profile area and the second profile area do not reduce walking comfort for the shoe wearer, it is preferably provided that the adhesion shells protrude to the same extent from the surface of the first profile area as the second profile area. It is preferably provided that the adhesion shells and/or the second profile areas are formed elastically so that they can adapt excellently to the ground without restricting the comfort of walking for the wearer.

In einer bevorzugten Ausführungsform sind die ersten Profilbereiche und die zweiten Profilbereiche alternierend zueinander an der Lauffläche angeordnet, um möglichst optimale Lauf- und Haftungseigenschaften zu erzielen.In a preferred embodiment, the first profile areas and the second profile areas are arranged alternately to one another on the tread in order to achieve the best possible running and adhesion properties.

Damit verdrängtes Wasser gezielt von den an den Untergrund anhaftenden Profilbereichen weggeleitet werden kann, sind die ersten Profilbereiche und die zweiten Profilbereiche durch Profilrinnen voneinander getrennt. In einer Ausführungsform laufen die Profilrinnen vorzugsweise in Richtung Sohlenrand und leiten so die Flüssigkeit nach Außen ab.The first profile areas and the second profile areas are separated from one another by profile channels so that displaced water can be directed away from the profile areas adhering to the ground. In one embodiment, the profile grooves preferably run in the direction of the edge of the sole and thus drain the liquid to the outside.

Die Erfindung umfasst ferner einen Schuh, der mit einer Außensohle mit den Merkmalen der oben beschriebenen Außensohle ausgestattet ist. Dabei kann es sich um einen beliebigen Männer- oder Damenschuh handeln. Die Erfindung kann ferner auch bei unterschiedlichen Schuharten oder Einsatzbereichen zum Tragen kommen, wobei je nach Belastung und Anforderung die beiden Profilbereiche in ihren Eigenschaften variieren können, sei es in der Shore-Härte der einzelnen Profilbereiche, der Anordnung der Profilbereiche auf der Laufsohle, der Positionierung und Aufbau der Haftungsschalen und die unterschiedlich starke Erhebung einzelner Profilbereiche gegenüber benachbarten Bereichen mit veränderter Shore-Härte.The invention also includes a shoe equipped with an outsole having the features of the outsole described above. This can be any male or female shoe. The invention can also be used with different types of shoes or areas of use, whereby the properties of the two profile areas can vary depending on the load and requirement, be it in the Shore hardness of the individual profile areas, the arrangement of the profile areas on the outsole, the positioning and structure of the adhesion shells and the different degrees of elevation of individual profile areas compared to neighboring areas with changed shore hardness.

Figur 1 zeigt den prinzipiellen Aufbau einer Außensohle, bestehend aus einem Ballenbereich 10 und einem Fersenbereich 20. figure 1 shows the basic structure of an outsole, consisting of a ball area 10 and a heel area 20.

Die erfindungsgemäße Profilierung umfasst in der gezeigten Variante am Ballenbereich 10 und Fersenbereich 20 mehrere erste Profilbereiche 2 und mehrere zweite Profilbereiche 3, wobei die Profilbereiche 2 bzw. 3 alternierend zueinander an der Lauffläche der Außensohle angeordnet sind. Jeder Profilbereich 2 bzw. 3 hat eine einzigartige Geometrie in Bezug auf Flächengröße und Form.In the variant shown, the profiling according to the invention comprises several first profile areas 2 and several second profile areas 3 on the ball area 10 and heel area 20, the profile areas 2 and 3 being arranged alternately to one another on the tread of the outsole. Each tread area 2 or 3 has a unique geometry in terms of area size and shape.

Die Oberfläche des ersten Profilbereichs 2 ist gegenüber der Oberfläche des zweiten Profilbereichs 3 derselben Ebene herabgesetzt, d.h. der zweite Profilbereich 3 ist gegenüber dem ersten Profilbereich 2 erhaben, solange kein Gewichtsdruck ausgeübt wird. Der erste Profilbereich 2 weist gegenüber dem zweiten Profilbereich 3 eine höhere Shore-Härte auf und ist elastisch ausgestaltet. Beim Auftreten wird der zweite Profilbereich 3 nach unten zum ersten Profilbereich 2 gedrückt. Der erste, härtere Profilbereich 2 umfasst zudem eine Vielzahl von Profilkörpern mit tetraedrischem Aufbau als Profil 9.The surface of the first profile area 2 is lower than the surface of the second profile area 3 of the same plane, i.e. the second profile area 3 is raised compared to the first profile area 2 as long as no weight pressure is exerted. The first profile area 2 has a higher Shore hardness than the second profile area 3 and is designed to be elastic. When stepping, the second profile area 3 is pressed down towards the first profile area 2 . The first, harder profile area 2 also includes a large number of profile bodies with a tetrahedral structure as profile 9.

Die Haftungsschale 4 ist auf der Stirnfläche konkav ausgebildet und umfasst eine Mulde 7, die von einer Außenlippe 6 umrandet ist. Dabei steht die Haftungsschale 4 in gleichem Maße gegenüber der Oberfläche des ersten Profilbereichs 2 über, wie der zweite Profilbereich 3.The adhesion shell 4 is concave on the end face and includes a trough 7 which is bordered by an outer lip 6 . The adhesion shell 4 protrudes to the same extent from the surface of the first profile area 2 as the second profile area 3.

Der zweite Profilbereich 3 ist mit einer Vielzahl wellenförmiger Lamellen als Profil 8 profiliert, die zumindest im Vorderfußbereich quer zur Längsachse der Lauffläche verlaufenThe second profile area 3 is profiled as a profile 8 with a large number of wave-shaped lamellae, which run transversely to the longitudinal axis of the tread, at least in the forefoot area

Die beiden Profilbereiche 2, 3 sind jeweils durch Innenrillen 5 voneinander abgegrenzt. Die Innenrillen 5 verlaufen in mehreren Bahnen sowohl entlang der Längsachse der Lauffläche als auch quer zur Längsachse der Lauffläche und münden in eine Außenrille 1.The two profile areas 2, 3 are each separated from one another by inner grooves 5. The inner grooves 5 run in several tracks both along the longitudinal axis of the tread and transversely to the longitudinal axis of the tread and end in an outer groove 1.

In Fig. 2 ist ein Ausschnitt einer erfindungsgemäßen Haftungsschale 4 gezeigt. Diese steht gegenüber der Oberfläche des ersten Profilbereichs 2 hervor und ist elastisch ausgebildet. Umrandet wird die Haftungsschale 4 durch die Außenlippe 6, welche die zentrale Mulde 7 umrandet. Beim Auftreten verkanten sich die Außenlippen 6 der Haftungsschale 4 mit der Oberfläche des Untergrundes. Bei glatten Oberflächen kann auch ein Unterdruck entstehen, ähnlich einem Saugnapf, bei dem sich die Außenlippen 6 an der glatten Oberfläche festsaugen und somit die Haftung verbessern.In 2 a section of an adhesion shell 4 according to the invention is shown. This protrudes from the surface of the first profile area 2 and is designed to be elastic. The adhesion shell 4 is bordered by the outer lip 6 which borders the central depression 7 . When stepping, the outer lips 6 of the adhesion shell 4 tilt with the surface of the ground. In the case of smooth surfaces, a negative pressure can also arise, similar to a suction cup, in which the outer lips 6 suck firmly on the smooth surface and thus improve adhesion.

Zu erkennen ist ferner die Profilierung des zweiten Profilbereiches 3 in Form eines Lamellenmusters bzw. der Profilkörper des ersten Profilbereichs. Zu sehen ist zudem, dass der zweite Profilbereich 3 gegenüber dem ersten Profilbereich 2 sowie die Haftungsschalen 4 erhaben sind und sich beim Auftreten aufgrund ihres elastischen Aufbaus komprimieren. Die Innenrillen 5 und die Außenrille 1 sorgen für einen effizienten Flüssigkeitsabtransport bei Nässe.The profiling of the second profile area 3 in the form of a lamellar pattern or the profile body of the first profile area can also be seen. It can also be seen that the second profile area 3 is raised compared to the first profile area 2 and the adhesion shells 4 and are compressed when you step on them due to their elastic structure. The inner grooves 5 and the outer groove 1 ensure efficient evacuation of liquids when wet.

In Fig. 3 ist der Absatzbereich 20 gezeigt, welcher ebenfalls die erfindungsgemäßen Eigenschaften und Merkmale aufweist. So sind im Fersenbereich 20 in der gezeigten Variante auch Lamellen als Profil 9 vorgesehen, wobei die Haftungsschalen 4 nicht nur quer zur Lauffläche, sondern auch schräg dazu an der Lauffläche angeordnet sind. Deutlich ist auch zu erkennen, wie die Haftungsschalen 4 in die einzelnen Ausnehmungen 11 eingelassen sind.In 3 the heel area 20 is shown, which also has the properties and features according to the invention. In the variant shown, slats are also provided as a profile 9 in the heel area 20, with the adhesion shells 4 not only being arranged transversely to the running surface, but also at an angle thereto on the running surface. It can also be clearly seen how the adhesion shells 4 are let into the individual recesses 11 .
