Description

Die vorliegende Erfindung betrifft eine Einlegesohle nach dem Oberbegriff des Anspruchs 1 sowie einen Schuh mit einer derartigen Einlegesohle.The present invention relates to an insole according to the preamble of claim 1 and a shoe with such an insole.

Bei der Entwicklung von Einlegesohlen und Schuhen ist es ein Ziel, dass beim Gehen/Laufen mit diesem Schuh auftretende Stoßbelastungen nicht oder nur in sehr geringem Umfang auf Knie- und Hüftgelenke und die Wirbelsäule übertragen werden und gleichzeitig eine physiologisch korrekte Abrollbewegung erhalten wird.In the development of insoles and shoes, it is a goal that when walking / running with this shoe occurring shock loads are not or only to a very limited extent on knee and hip joints and the spine are transmitted while maintaining a physiologically correct rolling motion.

Eine physiologisch korrekte Abrollbewegung wird idealerweise dadurch erreicht, indem der Schuh beim Auftreten ein Einsinken der Ferse ermöglicht und der Fuß anschließend über den Außenrist des Mittelfußbereiches zum Vorfußbereich in Form einer Walkbewegung abrollt. Eine derartige Bewegung wird auch als Spiralbewegung bezeichnet. Bei einem Schuh, der diese Bewegung unterstützt, wird die Stoßbelastung auf die empfindlichen Fuß- und Kniegelenke sowie die Belastung der Wirbelsäule beim Gehen und Stehen wesentlich gemindert.A physiologically correct rolling movement is ideally achieved by allowing the shoe to sink in when the heel falls, and then rolling the foot over the outer crotch of the midfoot area to the forefoot area in the form of a flexing motion. Such a movement is also called spiral movement. In a shoe that supports this movement, the impact load on the sensitive foot and knee joints as well as the strain on the spine when walking and standing is significantly reduced.

Ein derartiger Schuh ist beispielsweise in WO 2008/071443 beschrieben. Dieser Schuh besitzt eine erste Einlegesohle, die sich über die gesamte Länge des Schuhs erstreckt und die im Mittelfußbereich eine Laufwanne aufweist. Auf der Einlegesohle ist eine ebenfalls sich über die gesamte Schuhlänge erstreckende Schaumstoffauflage gelegt, die einen der Größe der Laufwanne entsprechenden Ausschnitt besitzt. Auf die Schaumstoffauflage ist eine zweite Einlegesohle gelegt, die die gesamte Schaumstoffauflage überdeckt und die im Mittelfußbereich an der Unterseite einen vorstehenden, der Laufwannenvertiefung entsprechenden kugel- oder ellipsoidsegmentförmigen Hohlkörper besitzt. Mit einem solchen Schuh ist eine physiologisch korrekte Abrollbewegung möglich, indem die zweite Einlegesohle über den kugel- oder ellipsoidsegmentförmigen Körper auf der ersten Einlegesohle abrollt, um die Spiralbewegung des Fußes zuzulassen und zu unterstützen. Die zweite Einlegesohle liegt dabei lose auf der Schaumstoffauflage und der ersten Einlegesohle auf und kann neben der Abrollbewegung auch eine bezüglich der Einlegesohle gewollte translatorische Relativbewegung im geringen Maße ausführen.Such a shoe is for example in WO 2008/071443 described. This shoe has a first insole which extends over the entire length of the shoe and which has a running trough in the metatarsal region. On the insole a likewise over the entire length of the shoe extending foam pad is laid, which has a size corresponding to the size of the tread cutout. On the foam pad a second insole is placed, which covers the entire foam pad and in the metatarsal area at the bottom has a protruding, the trough recess corresponding spherical or ellipsoidsegmentförmigen hollow body. With such a shoe a physiologically correct rolling movement is possible by the second insole rolls over the spherical or ellipsoidsegmentförmigen body on the first insole to allow the spiral movement of the foot and support. The second insole loosely rests on the foam pad and the first insole and can perform in addition to the rolling movement also a relative to the insole desired translational relative movement to a small extent.

Es hat sich herausgestellt, dass bei derartigen Schuhen es aufgrund der Relativbewegungen der zweiten Einlegesohle im Bezug auf die erste Einlegesohle und den die Sohlen umgebenen Schuh es zu einer Geräuschentwicklung durch Reibung der verschiedenen Komponenten zueinander kommen kann. Darüber hinaus kann die Bewegung der zweiten Einlegesohle in dem Schuh das Schuhinnenfutter durch Druck oder Reibung beschädigen.It has been found that in such shoes due to the relative movements of the second insole with respect to the first insole and the soles of the shoe surrounded it can cause a noise due to friction of the various components to each other. In addition, the movement of the second insole in the shoe can damage the shoe lining by pressure or friction.

Die Einlegesohlen des vorbekannten Schuhs sind aus einem harten, abriebfesten Material gefertigt, das nicht oder nur im geringen Maße durch Stanzen anpassbar ist. Dadurch ist für jede Schuhgröße und Schuhform eine eigene Werkzeugform zur Herstellung der Einlegesohlen notwendig, sodass die Herstellung derartiger Einlegesohlen relativ kostenintensiv ist.The insoles of the prior art shoe are made of a hard, abrasion resistant material that is not or only to a small extent customizable by punching. As a result, for each shoe size and shoe shape a separate tool shape for the production of insoles is necessary, so that the production of such insoles is relatively expensive.

Die vorbekannte dreiteilige Lösung aus erster Einlegesohle, Schaumstoffauflage und zweiter Einlegesohle ist auch bei der Produktion eines Schuhs unvorteilhaft, da mehrere Arbeitsschritte notwendig sind, um die einzelnen Komponenten in den Schuh einzulegen.The previously known three-part solution of the first insole, foam pad and second insole is also disadvantageous in the production of a shoe, since several steps are necessary to insert the individual components in the shoe.

Es ist daher die Aufgabe der vorliegenden Erfindung, eine Einlegesohle zu schaffen, die eine physiologisch korrekte Abrollbewegung des Fußes ermöglicht, wobei gleichzeitig die Einlegesohle flexibel einsetzbar und kostengünstig herstellbar sein soll. Ferner soll ein Schuh mit einer derartigen Einlegesohle bereitgestellt werden.It is therefore an object of the present invention to provide an insole that allows a physiologically correct rolling movement of the foot, at the same time the insole should be flexible and inexpensive to produce. Furthermore, a shoe is to be provided with such an insole.

Die Aufgabe wird durch die Merkmale der Ansprüche 1 und 12 gelöst.The object is solved by the features of claims 1 and 12.

Erfindungsgemäß ist vorgesehen, dass eine Einlegesohle für einen Schuh mit einem Fersenbereich, einem Mittelfußbereich und einem Vorfußbereich einen Schaumstoffkörper mit einer Oberseite und einer Unterseite aufweist, wobei sich der Schaumstoffkörper über den Fersenbereich, den Mittelfußbereich in den Vorfußbereich erstreckt. Mit anderen Worten: Der Schaumstoffkörper erstreckt sich über die gesamte Länge und Breite der Einlegesohle. Auf der Oberseite des Schaumstoffkörpers ist eine Deckschicht angeordnet. Der Schaumstoffkörper weist eine an der Oberseite des Schaumstoffkörpers in den Schaumstoffkörper eingelassene erste Platte auf, die sich über den Mittelfußbereich in den Fersenbereich erstreckt. Im Mittelfußbereich weist die erste Platte eine in Richtung der Unterseite konvex ausgebildete Verdickung auf. In dem Schaumstoffkörper ist ferner eine zweite Platte an der Unterseite des Schaumstoffkörpers eingelassen, die der konvex ausgebildeten Verdickung der ersten Platte gegenüberliegt. Die zweite Platte weist eine Abrollfläche für die konvexe Verdickung der ersten Platte auf, wobei die konvexe Verdickung der ersten Platte zum Bilden eines Drehpunktes für die erste Platte an der Abrollfläche der zweiten Platte anliegt.According to the invention, an insole for a shoe with a heel area, a metatarsal area and a forefoot area has a foam body with an upper side and a lower side, the foam body extending over the heel area, the midfoot area into the forefoot area. In other words, the foam body extends over the entire length and width of the insole. On the top of the foam body, a cover layer is arranged. The foam body has a first plate embedded in the foam body at the top of the foam body and extending over the midfoot area into the heel area. In the midfoot region, the first plate has a thickening which is convex toward the underside. In the foam body, a second plate is further embedded on the underside of the foam body, which is opposite to the convexly thickening of the first plate. The second plate has a convex thickening rolling surface of the first plate, the convex thickening of the first plate for forming a fulcrum for the first plate abutting against the rolling surface of the second plate.

Dabei bildet die konvex ausgebildete Verdickung im Rahmen der Erfindung eine konvex gewölbte Fläche, indem die Verdickung der ersten Platte nach allen Seiten hin abnimmt.In the context of the invention, the convexly formed thickening forms a convexly curved surface in that the thickening of the first plate decreases in all directions.

Durch das Vorsehen der konvex ausgebildeten Verdickung und einer der konvex ausgebildeten Verdickung gegenüberliegenden Abrollfläche ist es möglich, dass die erste Platte auf der zweiten Platte eine Dreh- bzw. Kippbewegung ausführt, die eine korrekte Abrollbewegung des Fußes bewirkt. Dadurch, dass die erste Platte in den Schaumstoffkörper eingelassen ist, steuert der Schaumstoffkörper die Bewegung der ersten Platte auf der zweiten Platte. Dadurch kann beispielsweise die Reibung der ersten Platte auf der zweiten Platte und die Reibung der ersten Platte an dem Schuhinnenfutter reduziert werden, sodass die daraus resultierende Geräuschentwicklung und Beschädigungen verringert werden können. Dadurch, dass die erste Platte in dem Schaumstoffkörper eingelassen ist, befindet sich teilweise Schaumstoffmaterial zwischen der konvex ausgebildeten Verdickung der ersten Platte und der Abrollfläche der zweiten Platte, sodass bei der Ausführung einer Schwenkbewegung der ersten Platte die daraus resultierende Abrollbewegung der konvexen Verdickung teilweise auf dem Schaumstoffmaterial ausgeführt wird. Dadurch ist die Abrollbewegung gedämpft und die Reibung zwischen der konvexen Verdickung und der Abrollfläche wird verringert, sodass nur ein geringer Verschleiß in diesen Komponenten auftritt.By providing the convexly formed thickening and a convexly formed thickening opposite rolling surface, it is possible that the first plate on the second plate performs a rotational or tilting movement, which causes a correct rolling movement of the foot. Characterized in that the first plate is embedded in the foam body, the foam body controls the movement of the first plate on the second plate. As a result, for example, the friction of the first plate on the second plate and the friction of the first plate on the shoe inner lining can be reduced, so that the resulting noise and damage can be reduced. The fact that the first plate is embedded in the foam body, is partially foam material between the convex thickening of the first plate and the rolling surface of the second plate, so that in the execution of a pivoting movement of the first plate, the resulting rolling movement of the convex thickening partially on the Foam material is performed. As a result, the rolling motion is damped and the friction between the convex thickening and the rolling surface is reduced, so that only a slight wear occurs in these components.

Dadurch dass sich die erste Platte ausschließlich über den Fersenbereich in den Mittelfußbereich erstreckt, besteht der Vorfußbereich der Einlegesohle im Wesentlichen nur aus dem Schaumstoffkörper und der darauf angeordneten Deckschicht. Dadurch ist ein Anpassen der Einlegesohle an einen Schuh auf einfache Art und Weise möglich, indem der Vorfußbereich der Einlegesohle entsprechend der Form des Schuhs ausgestanzt wird. Für unterschiedliche Schuhdesigns und teilweise sogar für unterschiedliche Schuhgrößen kann dabei die gleiche Einlegesohle verwendet werden, die durch Stanzen entsprechend angepasst wird. Dadurch kann mit der gleichen Werkzeugform für eine Vielzahl von Schuhen eine Einlegesohle hergestellt werden, wodurch die Produktionskosten deutlich verringert werden.Because the first plate extends exclusively over the heel area into the midfoot area, the forefoot area of the insole essentially consists only of the foam body and the cover layer arranged thereon. This makes it easy to adapt the insole to a shoe by punching out the forefoot part of the insole according to the shape of the shoe. For different shoe designs and sometimes even for different shoe sizes while the same insole can be used, which is adjusted by punching accordingly. This can be done with the same tool shape for a variety an insole can be made from shoes, thereby significantly reducing production costs.

Der Schaumstoffkörper ermöglicht im Fersenbereich ein elastisches Einsinken der ersten Platte, indem die erste Platte über den Drehpunkt entsprechend verschwenkt wird. Bei der Abrollbewegung über den Außenrist wird dann die Platte nach außen gekippt, bevor die Abrollbewegung durch das Aufsetzen der Fußballen im Vorfußbereich abgeschlossen wird. Dadurch, dass sich die erste Platte nur über den Fersen- und den Mittelfußbereich erstreckt, ist die Einlegesohle im Vorfußbereich besonders flexibel und weich gepolstert, wodurch eine besonders aktive Abrollbewegung des Fußes im Vorfußbereich bewirkt wird.The foam body allows in the heel area an elastic sinking of the first plate by the first plate is pivoted about the pivot point accordingly. During the rolling movement over the outer instep, the plate is then tilted outwards, before the rolling movement is completed by placing the foot pads in the forefoot area. The fact that the first plate extends only over the heel and the metatarsal area, the insole in the forefoot area is particularly flexible and soft padded, whereby a particularly active rolling movement of the foot in the forefoot area is effected.

Die erfindungsgemäße Einlegesohle ermöglicht ferner, dass der Träger eines Schuhs mit einer derartigen Einlegesohle beim Stehen in eine physiologische Grundhaltung gebracht wird, in welcher die Knie leicht angewinkelt sind, wodurch beim Stehen die Wirbelsäule entlastet wird. Ferner ist bedingt durch den Aufbau dieser Einlegesohle eine physiologisch richtige Haltung beim Gehen und Stehen erreichbar, sodass hierdurch die Muskulatur in natürlicher Weise aktiviert wird und somit die Gelenke entlastet werden. Dies kann beispielsweise erreicht werden, indem der Schaumstoffkörper im Fersenbereich deutlich dicker ausgeführt ist als im Vorfußbereich.The insole according to the invention also makes it possible that the wearer of a shoe is brought with such an insole when standing in a physiological basic attitude in which the knees are slightly angled, whereby the spine is relieved when standing. Furthermore, due to the structure of this insole, a physiologically correct posture when walking and standing can be achieved, so that in this way the muscles are activated in a natural way and thus the joints are relieved. This can be achieved, for example, by making the foam body significantly thicker in the heel area than in the forefoot area.

Über die unterschiedliche Ausgestaltung der Abrollflächen können unterschiedliche Sohlen bereit gestellt werden, die für unterschiedliche Belastungsarten der Sohle geeignet sind. Je nach Ausgestaltung der Abrollfläche ist der zwischen der konvexen Verdickung und der Abrollfläche befindliche Zwischenraum, der mit Schaumstoffmaterial ausgefüllt ist unterschiedlich gestaltet, sodass beispielsweise die Dämpfung der Abrollbewegung unterschiedlich gestaltet werden kann.Alternatively, the rolling surface may also be a convex surface. It is also possible that the rolling surface is formed as a flat surface. On the different design of the rolling surfaces different soles can be provided, which are suitable for different types of stress of the sole. Depending on the design of the rolling surface is between the Convex thickening and the rolling surface located space that is filled with foam material is designed differently, so that, for example, the damping of the rolling motion can be designed differently.

Die zweite Platte kann kleiner als die erste Platte ausgebildet sein, wobei vorzugsweise die zweite Platte ausschließlich im Mittelfußbereich angeordnet ist und/oder schmaler als die erste Platte ausgebildet ist. Da die zweite Platte lediglich eine Abrollfläche für die konvexe Verdickung der ersten Platte aufweisen. muss, kann die zweite Platte wesentlich kleiner als die erste Platte ausgebildet werden, sodass der die zweite Platte umgebene Bereich mit Schaumstoffmaterial ausgefüllt werden kann und der Tragekomfort der erfindungsgemäßen Einlegesohle besonders hoch ist.The second plate may be formed smaller than the first plate, wherein preferably the second plate is arranged exclusively in the midfoot region and / or is formed narrower than the first plate. Since the second plate only have a rolling surface for the convex thickening of the first plate. must, the second plate can be formed substantially smaller than the first plate, so that the area surrounding the second plate can be filled with foam material and the comfort of the insole according to the invention is particularly high.

In einem Ausführungsbeispiel der erfindungsgemäßen Einlegesohle ist vorgesehen, dass sich die Deckschicht über den Fersenbereich, den Mittelfußbereich und den Vorfußbereich erstreckt und vorzugsweise aus einem polsterndem Material besteht, wobei die Deckschicht vorzugsweise eine Auflageschicht aufweist. Durch das Vorsehen einer derartigen Deckschicht kann die gesamte Einlegesohle auf dem dem Fuß zugewandten Bereich in vorteilhafter Weise abgepolstert werden, sodass ein hoher Tragekomfort besteht. Dabei ist es insbesondere vorteilhaft, wenn die Deckschicht aus einem Material mit hoher Rückstellkraft besteht, sodass die Polsterfunktion auch bei häufigem Tragen der erfindungsgemäßen Einlegesohle gegeben ist. Über die Auflageschicht ist es möglich, die erfindungsgemäße Einlegesohle an die Anforderungen eines direkten Kontakts mit dem Fuß anzupassen, indem beispielsweise eine hohe Abriebfestigkeit, eine antibakterielle Eigenschaft, eine antiallergische Eigenschaft und/oder eine hautfreundliche Eigenschaft verwirklicht wird.In one exemplary embodiment of the insole according to the invention, it is provided that the cover layer extends over the heel area, the metatarsal area and the forefoot area and preferably consists of a cushioning material, wherein the cover layer preferably has a support layer.

Figuren 1-3 sind drei Ausführungsbeispiele von der erfindungsgemäßen Einlegesohle 1 schematisch im Schnitt dargestellt. Die Einlegesohlen der unterschiedlichen Ausführungsbeispiele der Fig. 1-3 sind im Wesentlichen identisch aufgebaut, wobei auf die Unterschiede nachfolgend im Einzelnen eingegangen wird. Figures 1-3 three embodiments of the insole according to the invention 1 are shown schematically in section. The insoles of the different embodiments of the Fig. 1-3 are essentially identical in structure, the differences being discussed in detail below.

Die Einlegesohle 1 erstreckt sich von einem Vorfußbereich 2 über einen Mittelfußbereich 3 zu einem Fersenbereich 4. Die einzelnen Bereiche sind in den Zeichnungen jeweils durch eine gestrichelte Linie voneinander getrennt.The insole 1 extends from a forefoot region 2 via a midfoot region 3 to a heel region 4. The individual regions are separated from one another in the drawings by a dashed line.

Die Einlegesohle 1 besteht aus einem Schaumstoffkörper 5, der eine Unterseite 6 und eine Oberseite 7 aufweist. Auf der Oberseite 7 des Schaumstoffkörpers 5 ist eine Deckschicht 9 angeordnet.The insole 1 consists of a foam body 5, which has a bottom 6 and a top 7. On the top 7 of the foam body 5, a cover layer 9 is arranged.

Auf der Oberseite 7 des Schaumstoffkörpers 5 ist eine erste Platte 11 eingelassen, die sich vom Fersenbereich 4 in den Mittelfußbereich 3 erstreckt.On the upper side 7 of the foam body 5, a first plate 11 is inserted, which extends from the heel region 4 into the midfoot region 3.

Im Mittelfußbereich weist die erste Platte 11 eine konvex ausgebildete Verdickung auf, die sich in Richtung der Unterseite 6 des Schaumstoffkörpers 5 erstreckt. Die Verdickung 13 ist dabei so ausgestaltet, dass sie zu allen Seiten hin verjüngt, sodass eine konvex gewölbte Fläche entsteht.In the midfoot region, the first plate 11 has a convexly formed thickening which extends in the direction of the underside 6 of the foam body 5. The thickening 13 is designed so that it tapers to all sides, so that a convexly curved surface is formed.

Der konvex ausgebildeten Verdickung 13 gegenüberliegend ist eine zweite Platte 15 angeordnet, die in die Unterseite 6 des Schaumstoffköpers 5 im Mittelfußbereich eingelassen ist. Die zweite Platte 15 weist eine Abrollfläche 17 auf, auf der die konvexe Verdickung 13 der ersten Platte 11 abrollen kann.The convexly shaped thickening 13 opposite a second plate 15 is arranged, which is embedded in the underside 6 of the foam body 5 in the metatarsal region. The second plate 15 has a rolling surface 17 on which the convex thickening 13 of the first plate 11 can roll.

Die erste Platte 11 und die zweite Platte 15 sind dabei in vorteilhafter Weise aus einem verschleißresistenten und abriebfesten Material hergestellt, das härter ist als das Schaumstoffmaterial des Schaumstoffkörpers 5.The first plate 11 and the second plate 15 are advantageously made of a wear-resistant and abrasion-resistant material, which is harder than the foam material of the foam body. 5

Die konvexe Verdickung 13 der ersten Platte 11 liegt an der Abrollfläche 17 der zweiten Platte 15 an, wobei ein Drehpunkt für die erste Platte 11 gebildet wird.The convex thickening 13 of the first plate 11 abuts against the rolling surface 17 of the second plate 15, wherein a fulcrum for the first plate 11 is formed.

Bei der Benutzung der erfindungsgemäßen Einlegesohle 1 sinkt der Fuß eines Benutzers beim Auftreten zunächst im Fersenbereich 4 elastisch in den Schaumstoffkörper 5 ein, wobei anschließend eine über den Außenrist erfolgte Abrollbewegung des Fußes über den Mittelfußbereich 3 zum Vorfußbereich 2 stattfindet, bevor im Vorfußbereich 2 die Fußballen auslaufend abrollen. Die erste Platte 11 unterstützt diese Bewegung, indem sie zunächst beim Absinken in dem Fersenbereich 4 in den Schaumstoffkörper 5 nach hinten gekippt wird, bevor bei der Abrollbewegung über den Außenrist ein seitliches Kippen der Platte 11 nach außen erfolgt. Dabei muss die Platte 11 auch im geringen Maße verformt werden, sodass es von Vorteil ist, wenn die erste Platte 11 im gewissen Maße elastisch ist. Dadurch wird die Eigenaktivität des Fußes bei Seitwärts- und Vorwärtsbewegungen unterstützt und nicht verhindert. Die auf der Oberseite 7 des Schaumstoffkörpers 5 angeordnete Deckschicht 9 ist aus einem polsternden Material hergestellt und polstert insbesondere die erste Platte 11, die aus einem relativ harten Material gefertigt ist, ab. Dadurch bietet die erfindungsgemäße Einlegesohle 1 einen hohen Tragekomfort.When using the insole according to the invention 1, the foot of a user initially sinks elastically into the foam body 5 in the heel area 4, wherein subsequently carried over the Außenrist rolling movement of the foot on the midfoot area 3 takes place forefoot area 2, before in the forefoot area 2 the ball of the foot unroll. The first plate 11 supports this movement by first being tilted back into the foam body 5 when sinking in the heel area 4, before the plate 11 is tilted outwards during the rolling movement over the outer crotch. In this case, the plate 11 must be deformed to a small extent, so it is advantageous if the first plate 11 is elastic to some extent. As a result, the intrinsic activity of the foot during sideways and forward movements is supported and not prevented. The cover layer 9 arranged on the upper side 7 of the foam body 5 is made of a cushioning material and, in particular, cushions the first plate 11, which is made of a relatively hard material. As a result, the insole 1 according to the invention offers a high wearing comfort.

Die Deckschicht 9 weist eine Auflageschicht 19 auf, die die Einlegesohle 1 für einen direkten Kontakt mit dem Fuß anpasst. Die Auflageschicht 19 kann beispielsweise eine hohe Abriebfestigkeit, antibakterielle Eigenschaften, antiallergische Eigenschaften und/oder hautfreundliche Eigenschaften aufweisen.The cover layer 9 has a support layer 19 which adapts the insole 1 for direct contact with the foot. The support layer 19 may, for example, have a high abrasion resistance, antibacterial properties, anti-allergic properties and / or skin-friendly properties.

Im Vorfußbereich 2 besteht die erfindungsgemäße Einlegesohle 1 lediglich aus dem Schaumstoffkörper 5 und der Deckschicht 9 mit der Auflageschicht 19, sodass in diesem Bereich der Fuß besonders weich abgepolstert wird, sodass die Abrollbewegung im Vorfußbereich 2 besonders vorteilhaft ausgeführt werden kann.In the forefoot region 2, the insole 1 according to the invention consists only of the foam body 5 and the cover layer 9 with the support layer 19, so that the foot is padded particularly soft in this area, so that the rolling motion in the forefoot 2 can be carried out particularly advantageous.

Bei der erfindungsgemäßen Einlegesohle 1 wird die Bewegung der ersten Platte 11 durch den Schaumstoffkörper 5 gedämpft und somit gesteuert. Der Schaumstoffkörper 5 lässt neben den Kippbewegungen der ersten Platte 11 um den Drehpunkt auch eine translatorische Bewegung im geringen Maße zu. Diese translatorische Bewegung ist gewollt, um die spiralförmige Bewegung während des Abrollens des Fußes in besonders vorteilhafter Weise zu unterstützen.In the insole 1 according to the invention, the movement of the first plate 11 is damped by the foam body 5 and thus controlled. The foam body 5, in addition to the tilting movements of the first plate 11 about the fulcrum and a translational movement to a small extent. This translational movement is intended to assist the helical movement during the rolling of the foot in a particularly advantageous manner.

Die unterschiedlichen erfindungsgemäßen Ausführungsbeispiele der Einlegesohle 1 der Fign. 1-3 unterscheiden sich lediglich in der Form der Abrollfläche 17 der ersten Platte 15. Während in Fig. 1 die Abrollfläche 17 konkav ausgebildet ist und von einem in Richtung der Oberseite 7 vorstehenden Rand 21 umgeben ist, ist die Abrollfläche 17 gemäß dem Ausführungsbeispiel der Fig. 2 als konvexe Fläche ausgebildet. In dem Ausführungsbeispiel der Fig. 3 ist die Abrollfläche 17 als ebene Fläche ausgebildet. Durch die unterschiedliche Ausgestaltung der Abrollfläche 17 ist die in dem Zwischenraum zwischen der Abrollfläche 17 und der konvexen Verdickung 13 angeordnete Menge von Schaumstoffmaterial unterschiedlich, sodass Einlegesohlen 1 mit unterschiedlichen Eigenschaften bereitgestellt werden können, indem die Dämpfung der ersten Platte 11 bei den Kippbewegungen unterschiedlich ausfällt.The different embodiments of the invention the insole 1 of FIGS. 1-3 differ only in the shape of the rolling surface 17 of the first plate 15. While in Fig. 1 the rolling surface 17 is concave and is surrounded by a 7 in the direction of the top edge 21, the rolling surface 17 according to the embodiment of Fig. 2 designed as a convex surface. In the embodiment of Fig. 3 the rolling surface 17 is formed as a flat surface. Due to the different configuration of the rolling surface 17, the arranged in the space between the rolling surface 17 and the convex thickening 13 amount of foam material is different, so insoles 1 can be provided with different properties by the damping of the first plate 11 is different in the tilting movements.

Die erste Platte 11 und die zweite Platte 15 können aus einem Kunststoff, beispielsweise Polyurethan hergestellt sein. Die Deckschicht 9 kann beispielsweise aus einem Latexschaum, einem Polyurethan-Schaum oder einem EVA-Schaum bestehen. Die Auflageschicht 19 kann beispielsweise ein Mikrofaserfleece oder ein Leder sein. Das Schaumstoffmaterial des Schaumstoffkörpers 5 kann beispielsweise ein geschäumter Kunststoff, beispielsweise ein geschäumtes Polyurethan sein.The first plate 11 and the second plate 15 may be made of a plastic, for example polyurethane. The cover layer 9 can for example consist of a latex foam, a polyurethane foam or an EVA foam. The overlay layer 19 may be, for example, a microfiber fleece or a leather. The foam material of the foam body 5 may be, for example, a foamed plastic, for example a foamed polyurethane.

In Fig. 4 ist ein weiteres Ausführungsbeispiel einer erfindungsgemäßen Einlegesohle 1 schematisch in der Draufsicht ohne Deckschicht gezeigt. Die erste Platte 11 ist in dem Schaumstoffkörper 5 eingelassen, wobei im Fersenbereich 4 und seitlich der ersten Platte 11 ein schmaler Rand 23 aus Schaumstoffmaterial gebildet ist, der die erste Platte 11 umgibt. Auf diese Weise wird eine Reibung der ersten Platte 11 mit dem die Einlegesohle 1 umgebenen Schuhinnenfutter fast vollständig vermieden, da der schmale Rand 23 zwischen der ersten Platte 11 und dem Schuhinnenfutter angeordnet ist und die Reibung somit deutlich verringert. Der schmale Rand 23 kann beispielsweise eine Breite von 1 mm aufweisen.In Fig. 4 is a further embodiment of an insole according to the invention 1 shown schematically in plan view without top layer. The first plate 11 is embedded in the foam body 5, wherein in the heel region 4 and the side of the first plate 11, a narrow edge 23 is formed of foam material surrounding the first plate 11. In this way, a friction of the first plate 11 with the insole 1 surrounded Schuannnenfutter is almost completely avoided, since the narrow edge 23 is disposed between the first plate 11 and the Schuhinnenfutter and thus significantly reduces the friction. The narrow edge 23 may, for example, have a width of 1 mm.

Wie aus Fig. 4 hervorgeht, in der die zweite Platte 15 und die Auflagefläche 17 schematisch und verdeckt dargestellt sind, ist die zweite Platte 15 wesentlich kleiner als die erste Platte 11 ausgebildet. Die zweite Platte 15, dient lediglich als Lager für die erste Platte 11, sodass die zweite Platte 15 nur wenig größer sein muss als die Abrollfläche 17. Dadurch kann Material für die zweite Platte 15 eingespart werden und die Einlegesohle 1 besitzt einen höheren Tragekomfort, da ein größerer Bereich mit Schaumstoffmaterial des Schaumstoffkörpers 5 ausgefüllt ist.How out Fig. 4 shows, in which the second plate 15 and the support surface 17 are shown schematically and hidden, the second plate 15 is substantially smaller than the first plate 11 is formed. The second plate 15, serves only as a bearing for the first plate 11, so that the second plate 15 must be only slightly larger than the rolling surface 17. This material can be saved for the second plate 15 and the insole 1 has a higher comfort, since a larger area is filled with foam material of the foam body 5.

Die konvexe Verdickung 13 und die zweite Platte 15 sind im Wesentlichen im Mittelfußbereich 3 angeordnet, wobei es besonders vorteilhaft ist, wenn die konvexe Verdickung 13 und die Abrollfläche 17 sich genau unterhalb des Schwerpunktes des Körpers des Trägers der Einlegesohle 1 befinden.The convex thickening 13 and the second plate 15 are arranged substantially in the midfoot region 3, wherein it is particularly advantageous if the convex thickening 13 and the rolling surface 17 are located just below the center of gravity of the body of the wearer of the insole 1.

Alle Komponenten der erfindungsgemäßen Einlegesohle 1 sind fest miteinander verbunden, sodass die erfindungsgemäße Einlegesohle 1 eine Einheit in Form einer Kassette bildet. Dadurch kann die erfindungsgemäße Einlegesohle 1 auf besonders einfache Art und Weise in einen Schuh eingelegt werden, was die Produktion eines Schuhs erleichtert. Auch kann die erfindungsgemäße Einlegesohle 1 als Nachrüstteil für vorhandene Schuhe eingesetzt werden.All components of the insole 1 according to the invention are firmly connected to each other, so that the insole according to the invention 1 forms a unit in the form of a cassette. As a result, the insole 1 according to the invention can be inserted into a shoe in a particularly simple manner, which facilitates the production of a shoe. Also, the insole 1 according to the invention can be used as a retrofit for existing shoes.
