Definitions
- the invention relates to a sole for a shoe, in particular sports / hiking shoe or ski / snowboard boot according to claim 1.
- US 4161828A discloses a sole according to the preamble of claim 1.
- Soles of the type mentioned here are basically known. They often have a damping profile, which is used, for example, in running shoes to achieve a pressure relief of the foot on the occurrence.
- a damping profile is on the outside, i. arranged on the floor covering facing side of the sole.
- the inside of the sole, i. so the foot-facing side is flat and has no profile. In this way, a comfortable bedding of the foot on the sole should be ensured.
- the damping of shocks is thus due to the sole material.
- the sole can be attenuated in this embodiment only within certain limits and above all only flat and not punctual. Since the minimum material thickness of a sole made of rubber is typically 2 mm, the damping profile must have a material thickness that is significantly thicker than 2 mm. The damping profile thus results in an increased material consumption, which is associated with a higher weight.
- Object of the present invention is therefore to provide a sole, which in addition to improved damping properties for compressive load also has a low material consumption.
- the above object is achieved by a sole with the features of claim 1.
- the sole serves to produce a shoe, in particular a sports / hiking shoe or ski / snowboard boot, and has a damping profile located on the outside of the sole.
- the sole is characterized by the fact that the damping profile also extends on the inside of the sole.
- An essential basic idea of the invention is that it is structurally not necessary to make the inside of the sole flat. On the one hand, a comfortable storage of the foot is achieved even if the damping profile also extends on the inside of the sole and on the other hand, the shoe upper is glued to the sole exclusively at the edge, so that even for the bonding of the sole with the shoe upper no
- a further advantage of a damping profile which also extends on the inside of the sole also results from the partial mechanical damping which can be achieved in this way. The damping is thus exactly where the pressure arises. As a result, a targeted pressure relief and pinpoint damping is possible.
- a damping profile formed on both sides of the sole results in a material and weight saving of the sole, because the damping profile is now completely integrated in the sole, so that no additional material is required for the damping profile.
- the double-sided damping profile also allows the formation of mutually independently acting damping elements, which in turn allow a pinpoint attenuation at the main pressure point at a load.
- the damping profile formed on both sides of the sole comprises at least one damping element.
- the at least one damping element has an elastically deformable hollow body, which is connected via material webs or material sections with further damping elements. Due to the hollow body-shaped design of the damping element results in addition to the improved damping properties and a material and thus weight savings of the sole. The sole can therefore be produced more cheaply.
- the at least one damping element is resiliently completely integrated into the sole and forms quasi a surface spring element.
- the damping element formed as a hollow body preferably has a corresponding connecting web and a holding web, which realize a resilient mounting of the damping element in the sole. In this way, the damping element can perform a substantially free spring movement in both directions perpendicular to a sole plane.
- the damping profile of the sole has a plurality of mutually independent damping elements, which comprise at least two main damping elements and a plurality of secondary damping elements.
- at least one main damping element in the heel area and at least one main damping element in the forefoot area of the sole are arranged.
- the main damping element is at least partially surrounded by secondary damping elements.
- a grip profile may additionally be formed in the heel area and / or in the forefoot area. This grip profile may also at least partially adjacent to the main damping elements and / or to the secondary damping elements and consist of a plurality of knob-like projections.
- the damping elements are preferably three-dimensional, in particular knob-like and have a polygonal, in particular hexagonal, or circular cup or truncated cone shape. In this way, the hollow body shape of the damping element can be generated.
- a frame can be provided, which is connected to the sole, in particular also in one piece, and preferably completely surrounds it.
- the frame is advantageously connected to the sole in such a way that it is arranged at a distance from the running plane of the sole, in particular at a distance of about 2 mm from it. In this way, the damping elements can be moved independently of the frame in the spring direction and generate a corresponding damping.
- the sole is at least about 2 mm thick and preferably has a continuous material thickness of about 2 mm, although the actual height of the sole may vary. This results in not only a saving of material, but also a weight saving of the sole.
- a shoe in particular a sports / hiking boot or a ski / snowboard boot with the features of claim 8 is proposed, having a sole according to one of claims 1-7.
- the Fig. 1 shows a cross-sectional view of a known from the prior art sole 10.
- the sole 10 is intended to be connected to a shaft 20.
- the Fig. 1 makes it clear that the conventional sole 10 has on its outer side 30 a damping profile 50, while the inner side 70 is formed flat.
- the Fig. 2 shows a cross-sectional view of a sole 1 according to the invention, which is provided for connection to a shaft 2 and for the production of any shoe, in particular a sports / hiking shoe or ski / snowboard boot used.
- the sole concept according to the invention can be used in the manufacture of any desired shoe. In the present case, the invention will be explained with reference to a sole for a snowboard boot.
- the damping profile 5 extends not only on the outside 3, but also on the inside 7 of the sole 1.
- the damping profile is thus quasi formed such that it passes through the sole.
- Under the outer side 3 of the sole is understood in the present case that side of the sole, which comes into contact with the floor covering, while the inner side 7 of the sole 1 forms the foot-facing side.
- the inside 7 is therefore not flat, but has, as well as the outside 3, the structure of the damping profile 5, so corresponding elevations and depressions.
- the sole is at the in Fig. 2 shown embodiment, provided with a frame 9, which serves to stabilize the sole, which may have a more flexible structure than conventional soles by the damping profile formed on both sides.
- the frame 9 may be integrally formed with the sole 1 or otherwise connected thereto, in particular glued.
- the frame 9 is connected to the outer edge of the sole 1 and surrounds it preferably completely.
- a lower edge R of the frame 9 is arranged at a distance a to a running plane L of the sole 1.
- the lower edge R is the part of the frame 9 which faces the ground, while the running plane L is the plane of the sole which comes into contact with the ground.
- the distance a between the running plane L and the lower edge R of the frame 9 may vary depending on the application. For example, it may be 2 mm or more.
- the Fig. 3 shows a side view of a shoe having a sole 1 according to the invention, which is connected to a frame 9.
- the Fig. 4A shows a longitudinal sectional view of the shoe according to Fig. 3 and thus a longitudinal section through a sole 1 according to the invention.
- the damping profile 5 extends both on the outside 3 and on the inside 7 of the sole 1.
- the damping profile 5 preferably extends over a majority of the total area of the sole 1 and is integrally formed therein. It has at least one, but preferably a plurality of damping elements 11, which are connected to one another via material regions and thus form at least a major part of the sole.
- the damping element 11 and its function are based on the Fig. 4B clarified. It becomes clear that the damping element 11 has a hollow body 13.
- the hollow body shape which is cup-shaped, results in the present example by a base 13 a, which is surrounded by a rising edge 13 b.
- the base 13a and the flank 13b include a cavity that is open to the foot side.
- the material thickness of the base and the flank can be identical and in particular be 2 mm. The same applies to the other material areas, webs and flanks, which form the sole.
- the hollow body 13 or the damping element 11 is resiliently integrated into the sole 1 and forms in this way a surface spring element.
- a spring movement as in Fig. 4B indicated to allow perpendicular to a sole plane E and that in both directions 19 and 19 ', the cup-shaped hollow body 13 via oblique edges, in particular over cross-sectional V- or Z-shaped flanks, connected to a material region, the connection to represents further damping elements.
- a connecting web 15 and a holding web 17 is provided, wherein the connecting web connects the hollow body with the holding web, which is either connected to the material region or forms this.
- the webs and the hollow body are elastically deformable and thereby allow a resilient mounting of the damping element in the sole 1.
- the damping element 11 can thus a spring movement in both directions 19 and 19 'substantially perpendicular to the sole plane E perform. Depending on the load situation, the damping element 11 experiences an elastic deformation, which is accompanied by a displacement in the direction of the arrows 19 or 19 '.
- the Fig. 5 shows a plan view of the outer side 3 of the sole 1 according to the invention.
- the damping elements are composed of main damping elements 21 and secondary damping elements 23.
- a main damping element 21 is arranged in the heel region 25 of the sole 1 and a main damping element 21 in the forefoot region 27 of the sole 1 in order to selectively achieve pressure relief and damping in the main stress zones.
- the main damping elements 21 are at least partially surrounded by the secondary damping elements 23.
- the secondary damping elements 23 In comparison to the main damping elements 21, the secondary damping elements 23 have a much smaller area or a smaller diameter, so that a larger number of secondary damping elements 23 than the main damping elements 21, the sole 1 can cover. For example, approximately 100 or more secondary damping elements 23 may be arranged between the two main damping elements 21.
- the main or secondary damping elements have a hexagonal shape. In principle, however, another polygonal shape, a circular shape or even a (semi-) spherical shape is conceivable. It is crucial that the damping elements for generating the hollow body shape are three-dimensional, so in particular knob-like and in particular a cup or truncated cone shape such that the damping elements form a hollow body which is closed to the inside 7 of the sole and closed to the outside of the sole ,
- both in the heel region 25 and in the forefoot 27 each have a grip profile 29, which are responsible as profile knobs exclusively for the grip and develop no damping effect.
- the grip regions 29 are optional and can also be replaced by damping elements, so that the entire sole is composed of damping elements and material regions arranged therebetween.
- Fig. 5 makes it clear that areas of different size damping elements can be provided.
- all sub-damping elements 23 and main damping elements 21 have the same dimensions.
- the secondary damping elements can be designed differently large.
- the main damping elements must not have identical shapes and sizes.
- the hexagonal shape of the damping elements is not necessarily applicable to each damping element. Also conceivable is a mixture of differently designed, for example polygonal and circular damping elements on a sole 1.
- the secondary damping elements and main damping elements differ essentially by their purpose and their damping effect. It is particularly advantageous if the main damping elements are arranged with increased damping effect in the zones of high pressure, in particular in the heel and forefoot area. In principle, however, any "design" by the damping elements can be realized.
- the sole may be completely or only partially penetrated by damping elements, wherein the distribution of different types of damping elements to any shoe and purpose is individually adjustable.
- the mode of action of the resiliently mounted damping elements 11 will be described below with reference to the longitudinal sectional views of the sole 1 according to the Fig. 6-8 explained.
- the in the Fig. 6-8 shown longitudinal section runs essentially through in the Fig. 5 shown main damping elements 21, the in Fig. 4A or 4B shown damping elements 11 correspond.
- the Fig. 6 shows a starting situation in which a sole 1 is shown in an unloaded state.
- the Fig. 7 shows a situation in which the damping elements 11 a damping effect to the inside 7 of the sole 1 unfold.
- the resiliently mounted hollow body of the damping element is elastically displaced towards the inside of the sole 1.
- the damping elements in the sole 1 can thus be a spot attenuation by particularly stressed areas.
- the sprung bearing and the resulting possibility of a spring movement of the damping elements in both directions perpendicular to the sole plane, allows partial mechanical damping. Due to the hollow body-shaped design of the damping elements, however, not only a particularly good damping is ensured by the spring mounting of the damping elements, but this design of the damping elements also results in a material and weight savings of the sole. It is thus cheaper to produce than conventional soles.
- the sole ultimately comprises a multiplicity of surface spring elements which, depending on their degree of expression, can develop a different damping effect.
- damping elements are arranged over material areas separated from each other and thus could independently, i. E. essentially unaffected by each other, each fulfill their damping function.
- the sole can thus be designed individually.
- the sole material is in principle not subject to any restrictions.
- the sole may be made of rubber or any other material suitable for sole production.
- the invention provides a particularly advantageous sole, which can be generated by a two-sided profiling and thereby (hollow body-shaped)
- Damping elements on the one hand material and weight savings and on the other hand an optimal and pinpoint pressure relief and damping achieved.

Description
Die Erfindung betrifft eine Sohle für einen Schuh, insbesondere Sport-/Wanderschuh oder Ski-/Snowboardstiefel gemäß dem Anspruch 1.
Sohlen der hier angesprochenen Art sind grundsätzlich bekannt. Sie weisen häufig ein Dämpfungsprofil auf, welches beispielsweise bei Laufschuhen zum Einsatz kommt, um eine Druckentlastung des Fußes beim Auftreten zu erreichen. Bei den herkömmlichen Schuhen ist ein derartiges Dämpfungsprofil an der Außenseite, d.h. auf der dem Bodenbelag zugewandten Seite der Sohle angeordnet. Die Innenseite der Sohle, d.h. also die dem Fuß zugewandte Seite, ist hingegen flach und weist kein Profil auf. Auf diese Weise soll eine bequeme Bettung des Fußes auf der Sohle gewährleistet werden. Die Dämpfung von Schlägen erfolgt folglich durch das Sohlenmaterial. Die Sohle lässt sich bei dieser Ausgestaltung nur in gewissen Grenzen und vor allem nur flächig und nicht punktuell dämpfen. Da die Mindestmaterialstärke einer Sohle aus Gummi typischerweise 2 mm beträgt, muss das Dämpfungsprofil eine Materialstärke aufweisen, die deutlich dicker ist als 2 mm. Das Dämpfungsprofil resultiert also in einem erhöhten Materialverbrauch, der mit einem höheren Gewicht einhergeht.Soles of the type mentioned here are basically known. They often have a damping profile, which is used, for example, in running shoes to achieve a pressure relief of the foot on the occurrence. In conventional shoes, such a damping profile is on the outside, i. arranged on the floor covering facing side of the sole. The inside of the sole, i. so the foot-facing side, however, is flat and has no profile. In this way, a comfortable bedding of the foot on the sole should be ensured. The damping of shocks is thus due to the sole material. The sole can be attenuated in this embodiment only within certain limits and above all only flat and not punctual. Since the minimum material thickness of a sole made of rubber is typically 2 mm, the damping profile must have a material thickness that is significantly thicker than 2 mm. The damping profile thus results in an increased material consumption, which is associated with a higher weight.
Aufgabe der vorliegenden Erfindung ist es daher, eine Sohle zu schaffen, die neben verbesserten Dämpfungseigenschaften zur Druckbelastung auch einen geringen Materialverbrauch aufweist.Object of the present invention is therefore to provide a sole, which in addition to improved damping properties for compressive load also has a low material consumption.
Die oben genannte Aufgabe wird durch eine Sohle mit den Merkmalen des Anspruchs 1 gelöst. Die Sohle dient zur Herstellung eines Schuhs, insbesondere eines Sport-/Wanderschuhs oder Ski-/Snowboardstiefels, und weist ein an der Außenseite der Sohle befindliches Dämpfungsprofil auf. Die Sohle zeichnet sich dadurch aus, dass sich das Dämpfungsprofil auch auf der Innenseite der Sohle erstreckt.The above object is achieved by a sole with the features of
Ein wesentlicher Grundgedanke der Erfindung liegt darin, dass es konstruktiv nicht notwendig ist, die Innenseite der Sohle flach auszubilden. Zum einen wird eine bequeme Lagerung des Fußes auch dann erreicht, wenn sich das Dämpfungsprofil auch auf der Innenseite der Sohle erstreckt und zum anderen wird der Schuhschaft mit der Sohle ausschließlich an deren Rand verklebt, so dass auch für das Verkleben der Sohle mit dem Schuhschaft keine flache Innenseite der Sohle erforderlich ist, Ein weiterer Vorteil eines sich auch auf der Innenseite der Sohle erstreckenden Dämpfungsprofils ergibt sich darüber hinaus durch die partielle mechanische Dämpfung, die hierdurch erzielt werden kann. Die Dämpfung erfolgt also genau dort, wo der Druck entsteht. Hierdurch ist eine gezielte Druckentlastung und eine punktgenaue Dämpfung möglich. Durch ein auf beiden Seiten der Sohle ausgebildetes Dämpfungsprofil ergibt sich darüber hinaus eine Material- und Gewichtsersparnis der Sohle, weil das Dämpfungsprofil nun vollständig in die Sohle integriert ist, sodass kein zusätzliches Material für das Dämpfungsprofil erforderlich ist. Das beidseitig ausgebildete Dämpfungsprofil ermöglicht weiterhin die Ausbildung von unabhängig voneinander agierenden Dämpfungselementen, die wiederum eine punktgenaue Dämpfung an der Hauptdruckstelle bei einer Belastung ermöglichen.An essential basic idea of the invention is that it is structurally not necessary to make the inside of the sole flat. On the one hand, a comfortable storage of the foot is achieved even if the damping profile also extends on the inside of the sole and on the other hand, the shoe upper is glued to the sole exclusively at the edge, so that even for the bonding of the sole with the shoe upper no A further advantage of a damping profile which also extends on the inside of the sole also results from the partial mechanical damping which can be achieved in this way. The damping is thus exactly where the pressure arises. As a result, a targeted pressure relief and pinpoint damping is possible. Moreover, a damping profile formed on both sides of the sole results in a material and weight saving of the sole, because the damping profile is now completely integrated in the sole, so that no additional material is required for the damping profile. The double-sided damping profile also allows the formation of mutually independently acting damping elements, which in turn allow a pinpoint attenuation at the main pressure point at a load.
Besonders vorteilhaft ist es, dass das zu beiden Seiten der Sohle ausgebildete Dämpfungsprofil mindestens ein Dämpfungselement umfasst. Das mindestens eine Dämpfungselement weist einen elastisch verformbaren Hohlkörper auf, der über Materialstege bzw. Materialabschnitte mit weiteren Dämpfungselementen verbunden ist. Durch die hohlkörperförmige Ausbildung des Dämpfungselements ergibt sich neben den verbesserten Dämpfungseigenschaften auch eine Material- und damit Gewichtsersparnis der Sohle. Die Sohle kann folglich kostengünstiger hergestellt werden.It is particularly advantageous that the damping profile formed on both sides of the sole comprises at least one damping element. The at least one damping element has an elastically deformable hollow body, which is connected via material webs or material sections with further damping elements. Due to the hollow body-shaped design of the damping element results in addition to the improved damping properties and a material and thus weight savings of the sole. The sole can therefore be produced more cheaply.
Das mindestens eine Dämpfungselement ist federelastisch vollständig in die Sohle integriert und bildet quasi ein Flächenfederelement. Hierzu weist das als Hohlkörper ausgebildete Dämpfungselement vorzugsweise einen entsprechende Verbindungssteg und einen Haltesteg auf, die eine federelastische Lagerung des Dämpfungselements in der Sohle realisieren. Auf diese Weise kann das Dämpfungselement eine im Wesentlichen freie Federbewegung in beiden Richtungen senkrecht zu einer Sohlenebene durchführen.The at least one damping element is resiliently completely integrated into the sole and forms quasi a surface spring element. For this purpose, the damping element formed as a hollow body preferably has a corresponding connecting web and a holding web, which realize a resilient mounting of the damping element in the sole. In this way, the damping element can perform a substantially free spring movement in both directions perpendicular to a sole plane.
Das Dämpfungsprofil der Sohle weist mehrere voneinander unabhängige Dämpfungselemente auf, die mindestens zwei Hauptdämpfungselemente und eine Vielzahl von Nebendämpfungselementen umfassen. Dabei sind mindestens ein Hauptdämpfungselement im Fersenbereich und mindestens ein Hauptdämpfungselement im Vorfußbereich der Sohle angeordnet. Weiterhin ist das Hauptdämpfungselement zumindest bereichsweise von Nebendämpfungselementen umgeben. Im Fersenbereich und/oder im Vorfußbereich kann im Übrigen zusätzlich ein Grip-Profil ausgebildet sein. Dieses Grip-Profil kann ebenfalls zumindest bereichsweise an die Hauptdämpfungselemente und/oder an die Nebendämpfungselemente angrenzen und aus einer Mehrzahl von noppenartigen Vorsprüngen bestehen.The damping profile of the sole has a plurality of mutually independent damping elements, which comprise at least two main damping elements and a plurality of secondary damping elements. In this case, at least one main damping element in the heel area and at least one main damping element in the forefoot area of the sole are arranged. Furthermore, the main damping element is at least partially surrounded by secondary damping elements. Incidentally, a grip profile may additionally be formed in the heel area and / or in the forefoot area. This grip profile may also at least partially adjacent to the main damping elements and / or to the secondary damping elements and consist of a plurality of knob-like projections.
Die Dämpfungselemente sind vorzugsweise dreidimensional, insbesondere noppenartig ausgebildet und weisen eine polygonale, insbesondere hexagonale, oder kreisförmige Becher- oder Kegelstumpfform auf. Auf diese Weise kann die Hohlkörperform des Dämpfungselements erzeugt werden. Zur Stabilisierung des Dämpfungsprofils kann darüber hinaus ein Rahmen vorgesehen sein, der mit der Sohle, insbesondere auch einstückig, verbunden ist und diesen vorzugsweise vollständig umgibt. Der Rahmen ist vorteilhafterweise derart mit der Sohle verbunden, dass er in einem Abstand zur Laufebene der Sohle, insbesondere in einem Abstand von ca. 2 mm, zu dieser angeordnet ist. Auf diese Weise können die Dämpfungselemente unabhängig von dem Rahmen in der Federrichtung bewegt werden und eine entsprechende Dämpfung erzeugen. Die Sohle ist mindestens ca. 2 mm dick und weist vorzugsweise eine durchgängige Materialdicke von ca. 2 mm auf, wobei die tatsächliche Höhe der Sohle jedoch variieren kann. Dadurch ergibt sich nicht nur eine Materialersparnis, sondern auch eine Gewichtsersparnis der Sohle.The damping elements are preferably three-dimensional, in particular knob-like and have a polygonal, in particular hexagonal, or circular cup or truncated cone shape. In this way, the hollow body shape of the damping element can be generated. To stabilize the damping profile, moreover, a frame can be provided, which is connected to the sole, in particular also in one piece, and preferably completely surrounds it. The frame is advantageously connected to the sole in such a way that it is arranged at a distance from the running plane of the sole, in particular at a distance of about 2 mm from it. In this way, the damping elements can be moved independently of the frame in the spring direction and generate a corresponding damping. The sole is at least about 2 mm thick and preferably has a continuous material thickness of about 2 mm, although the actual height of the sole may vary. This results in not only a saving of material, but also a weight saving of the sole.
Zur Lösung der oben genannten Aufgabe wird auch ein Schuh, insbesondere ein Sport-/Wanderschuh oder ein Ski-/Snowboardstiefel mit den Merkmalen des Anspruchs 8 vorgeschlagen, der eine erfindungsgemäße Sohle nach einem der Ansprüche 1-7 aufweist.To solve the above object, a shoe, in particular a sports / hiking boot or a ski / snowboard boot with the features of claim 8 is proposed, having a sole according to one of claims 1-7.

Im Gegensatz zu einer herkömmlichen Sohle erstreckt sich das Dämpfungsprofil 5 nicht nur auf der Außenseite 3, sondern auch auf der Innenseite 7 der Sohle 1. Das Dämpfungsprofil ist also quasi derart ausgebildet, dass es die Sohle durchsetzt. Unter der Außenseite 3 der Sohle wird vorliegend diejenige Seite der Sohle verstanden, die mit dem Bodenbelag in Berührung kommt, während die Innenseite 7 der Sohle 1 die dem Fuß zugewandte Seite bildet. Die Innenseite 7 ist folglich nicht flach ausgebildet, sondern weist, wie auch die Außenseite 3, die Struktur des Dämpfungsprofils 5, also entsprechende Erhebungen und Vertiefungen auf.In contrast to a conventional sole, the damping profile 5 extends not only on the outside 3, but also on the

Die Stege und auch der Hohlkörper sind elastisch verformbar und ermöglichen dadurch eine federelastische Lagerung des Dämpfungselements in der Sohle 1. Das Dämpfungselement 11 kann somit eine Federbewegung in beide Richtungen 19 und 19' im Wesentlichen senkrecht zur Sohlenebene E durchführen. Je nach Belastungssituation erfährt das Dämpfungselement 11 eine elastische Verformung, die einhergeht mit einer Verlagerung in Richtung der Pfeile 19 oder 19'.The webs and the hollow body are elastically deformable and thereby allow a resilient mounting of the damping element in the sole 1.

Die Nebendämpfungselemente und Hauptdämpfungselementen unterscheiden sich im Wesentlichen durch ihren Einsatzzweck und ihre Dämpfungswirkung. Besonders vorteilhaft ist es, wenn die Hauptdämpfungselemente mit erhöhter Dämpfungswirkung in den Zonen hoher Druckeinwirkung, insbesondere also im Fersen- und Vorfußbereich, angeordnet sind. Grundsätzlich ist jedoch jedes beliebige "Design" durch die Dämpfungselemente realisierbar. Beispielsweise kann die Sohle vollständig oder nur teilweise von Dämpfungselementen durchsetzt sein, wobei die Verteilung von verschiedenartigen Dämpfungselementen an jeden beliebigen Schuh und Einsatzzweck individuell anpassbar ist.The secondary damping elements and main damping elements differ essentially by their purpose and their damping effect. It is particularly advantageous if the main damping elements are arranged with increased damping effect in the zones of high pressure, in particular in the heel and forefoot area. In principle, however, any "design" by the damping elements can be realized. For example, the sole may be completely or only partially penetrated by damping elements, wherein the distribution of different types of damping elements to any shoe and purpose is individually adjustable.

Durch eine zweckmäßige Integration der Dämpfungselemente in die Sohle 1 kann folglich eine punktgenaue Dämpfung durch besonders beanspruchte Bereiche erfolgen. Die gefederte Lagerung und die dadurch resultierende Möglichkeit einer Federbewegung der Dämpfungselemente in beiden Richtungen senkrecht zur Sohlenebene, ermöglicht eine partielle mechanische Dämpfung. Durch die hohlkörperförmige Ausbildung der Dämpfungselemente ist jedoch nicht nur eine besonders gute Dämpfung durch die Federlagerung der Dämpfungselemente gewährleistet, sondern diese Ausgestaltung der Dämpfungselemente resultiert auch in einer Material- und Gewichtsersparnis der Sohle. Sie ist damit kostengünstiger herstellbar als herkömmliche Sohlen. Die Sohle umfasst bei einer flächendeckenden Anordnung von Dämpfungselementen letztendlich eine Vielzahl von Flächenfederelementen, die je nach ihrem Ausprägungsgrad eine unterschiedliche Dämpfungswirkung entfalten können. Diese Dämpfungselemente sind über Materialbereiche getrennt voneinander angeordnet und könnten somit unabhängig voneinander, d.h. im Wesentlichen unbeeinflusst voneinander, jeweils ihre Dämpfungsfunktion erfüllen. Je nach Schuh und entsprechendem Anwendungsfall kann die Sohle somit individuell ausgestaltet werden. Nicht nur die Ausgestaltung und Anordnung der Dämpfungselemente kann jedoch variieren, sondern auch das Sohlenmaterial ist prinzipiell keinen Beschränkungen unterlegen. Beispielsweise kann die Sohle aus Gummi oder auch aus jedem anderen Material, das sich für die Sohlenherstellung eignet, hergestellt werden.By an appropriate integration of the damping elements in the sole 1 can thus be a spot attenuation by particularly stressed areas. The sprung bearing and the resulting possibility of a spring movement of the damping elements in both directions perpendicular to the sole plane, allows partial mechanical damping. Due to the hollow body-shaped design of the damping elements, however, not only a particularly good damping is ensured by the spring mounting of the damping elements, but this design of the damping elements also results in a material and weight savings of the sole. It is thus cheaper to produce than conventional soles. In the case of a comprehensive arrangement of damping elements, the sole ultimately comprises a multiplicity of surface spring elements which, depending on their degree of expression, can develop a different damping effect. These damping elements are arranged over material areas separated from each other and thus could independently, i. E. essentially unaffected by each other, each fulfill their damping function. Depending on the shoe and the corresponding application, the sole can thus be designed individually. However, not only the design and arrangement of the damping elements may vary, but also the sole material is in principle not subject to any restrictions. For example, the sole may be made of rubber or any other material suitable for sole production.
