Description

Die Erfindung betrifft ein Schuhsohlensystem gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a shoe sole system according to the preamble of claim 1.

Schuhe bestehen üblicherweise aus einem Schuhoberteil und einer daran befestigten Schuhsohle. Die Schuhsohle ist entweder an das Schuhoberteil angeklebt bzw. angegossen, wie z.B. bei Schuhen mit Brandsohle oder bei gestrobelten Schuhen, oder direkt mit dem Schuhoberteil vernaht.Shoes usually consist of a shoe upper and a shoe sole attached to it. The sole of the shoe is either glued or cast onto the upper, e.g. in the case of shoes with an insole or in the case of strobed shoes, or directly stitched to the upper of the shoe.

Damit die eigentliche Schuhsohle nicht zu schwer ist und auch bei größerer Dicke elastisch bleibt, sind im Fersenbereich und/oder im Vorfußbereich Hohlräume eingearbeitet, die untereinander durch eine gitterartige Struktur getrennt sind.So that the actual shoe sole is not too heavy and remains elastic even with a greater thickness, cavities are incorporated in the heel area and / or in the forefoot area, which are separated from one another by a grid-like structure.

Bei bekannten Schuhen mit Brandsohle kann zwar der Vorteil der Gewichtsreduzierung durch die Hohlräume in der Schuhsohle genutzt werden, die feste Verklebung der an sich bereits relativ steifen Brandsohle mit der eigentlichen Schuhsohle schränkt die elastischen Eigenschaften der mit gewichtsreduzierenden Hohlräumen versehenen Schuhsohle jedoch stark ein und führt zu einem relativ steifen Schuh.In known shoes with an insole, the advantage of weight reduction through the cavities in the shoe sole can be used, but the firm adhesion of the already relatively stiff insole to the actual shoe sole severely limits and leads to the elastic properties of the shoe sole provided with weight-reducing cavities a relatively stiff shoe.

Schaumstoff (PU), d.h. gitterartige Hohlräume sind in der Sohle nicht vorhanden.Foam (PU), i.e. There are no lattice-like cavities in the sole.

Des weiteren ist eine sogenannte Lightweight-Sohle bekannt, in die ein System für Energierückgabe und Auftrittsdämpfung eingearbeitet, die ebenfalls fest mit der Sohle verbunden ist.A so-called lightweight sole is also known, into which a system for energy return and shock absorption is incorporated, which is also firmly connected to the sole.

Des weiteren ist ein sogenanntes "Freshness-System"-Schuhsohlensystem bekannt, das aus mehreren separaten zusammenfügbaren Teilen aufgebaut ist. Dieses System dient der Unterbringung einer Duftkapsel in einer Fersenunterstützung des Sohlensystems. Durch Anritzen einer die Duftkapsel umgebenden Folie entfaltet sich der Duft. Über Luftkanäle Kleiner Abmessungen gelangt der Duftstoff durch entsprechende Löcher in der Einlegesohle zum Fußbereich. Dieses Schuhsohlensystem ist aus dem Schuh herausnehmbar, damit die verbrauchte Duftkapsel gegen eine neue ausgetauscht werden kann. Gewichtsreduzierende Ausnehmungen sind lediglich in der Fersenunterstützung und in geringem Umfang angeordnet. Das die Kapsel und die Luftkanäle tragende Schuhsohlensystem ist relativ fest ausgeführt, damit weder die Luftkanäle noch die Fersenunterstützung zusammengedrückt werden können.Furthermore, a so-called "freshness system" shoe sole system is known, which is made up of several separate parts that can be joined together. This system is used to accommodate a scent capsule in a heel support of the sole system. By scoring a film surrounding the fragrance capsule, the fragrance unfolds. Via small size air channels, the fragrance reaches the foot area through corresponding holes in the insole. This shoe sole system can be removed from the shoe so that the used fragrance capsule can be exchanged for a new one. Weight-reducing recesses are only arranged in the heel support and to a small extent. The shoe sole system carrying the capsule and the air channels is relatively firm, so that neither the air channels nor the heel support can be compressed.

Es ist deshalb das Ziel der Erfindung, ein Schuhsohlensystem zu schaffen, das das Fußklima im Schuh verbessert, elastisch ist, kostengünstig herstellbar und für unterschiedliche Schuhtypen anwendbar ist.It is therefore the object of the invention to provide a shoe sole system which improves the foot climate in the shoe, is elastic, can be produced inexpensively and can be used for different types of shoes.

Dieses Ziel wird durch ein Schuhsohlensystem mit den Merkmalen gemäß Anspruch 1 erreicht. Zweckmäßige Weiterbildungen sind in den Unteransprüchen definiert.This goal is achieved by a shoe sole system with the features according to claim 1. Appropriate further training is defined in the subclaims.

Das erfindungsgemäße Schuhsohlensystem besteht aus einer Vielzahl von untereinander durch Luftkanäle verbundenen Luftkammern, die ein Luftkammersystem bilden. Diese Luftkammern sind unter Belastung flexibel, d.h. deformierbar.The shoe sole system according to the invention consists of a multiplicity of air chambers which are connected to one another by air channels and form an air chamber system. These air chambers are flexible under load, i.e. deformable.

Damit durch den beim Gehen ausgeübten Druck während des Bewegungsablaufs, d.h. beim Abrollen des Fußes, Luft aus den Luftkammern der Sohle an den Fuß zirkulieren kann, ist das Fußbett luftdurchlässig ausgeführt, wodurch eine Verbindung des Schuhinnenbereiches mit zumindestens einem Teil der Vielzahl von Luftkammern des Luftkammersystems vorhanden ist. Das erfindungsgemäße Schuhsohlensystem ist somit ein atmungsaktives Schuhsohlensystem, das wegen der Elastizität des Schuhsohlen- bzw. Laufsohlermaterials sowie der das Luftkammersystem bildenden Stege eine optimale Energierückgabe mit idealer Auftrittsdämpfung schafft. Darüber hinaus entsteht durch das Luftkammersystem in Verbindung mit dem Bewegungsablauf beim Abrollen des Fußes ein durch die Luftzirkulation bewirktes angenehmes Schuhklima. Mit der Erfindung wird somit ein Schuhsohlensystem geschaffen, das ein leichtes ermüdungsfreies Gehen bei angenehmem Schuhklima realisiert.Thus, by the pressure exerted while walking during the course of movement, i.e. When the foot rolls off, air can circulate from the air chambers of the sole to the foot, the footbed is made permeable to air, as a result of which the interior of the shoe is connected to at least part of the plurality of air chambers of the air chamber system. The shoe sole system according to the invention is thus a breathable shoe sole system which, due to the elasticity of the shoe sole or outsole material and the webs forming the air chamber system, creates an optimal energy return with ideal shock absorption. In addition, the air chamber system in conjunction with the movement sequence when the foot rolls off creates a pleasant shoe climate caused by the air circulation. The invention thus creates a shoe sole system that realizes easy, fatigue-free walking with a pleasant shoe climate.

Vorzugsweise ist das Luftkammersystem an der Unterseite des Fußbettes zumindest teilweise fest angebracht. Es kann separat gefertigt und an der Unterseite des Fußbettes angeklebt sein; es kann aber auch in einem Stück mit dem Fußbett hergestellt sein. Dieses an der Unterseite des Fußbettes angebrachte Luftkammersystem ist in die Schuhsohle einlegbar.The air chamber system is preferably at least partially firmly attached to the underside of the footbed. It can be made separately and glued to the bottom of the footbed; but it can also be made in one piece with the footbed. This air chamber system, which is attached to the underside of the footbed, can be inserted into the sole of the shoe.

Da das Fußbett als Einlegesohle bei Schuhen ausgeführt ist, bei denen die Laufsohle mit dem Schuhoberteil vernäht ist, ist darüber hinaus das Fußbett aus dem Schuh herausnehmbar und kann leicht gereinigt werden. Das Fußbett mit dem an der Unterseite befindlichen Luftkammersystem ist dabei aus einem solchen Material hergestellt, daß es leicht z.B. in einer herkömmlichen Waschmaschine gewaschen werden kann.Since the footbed is designed as an insole for shoes in which the outsole is sewn to the upper of the shoe, the footbed can also be removed from the shoe and can be easily cleaned. The footbed with the air chamber system on the underside is made of such a material that it can easily be washed, for example, in a conventional washing machine.

Das erfindungsgemäße Schuhsohlensystem kann ebenfalls für gestrobelte Schuhe verwendet werden. Bei gestrobelten Schuhen ist jedoch das Obermaterial des Schuhs nach unten hin zum Sohlenbereich durch ein textiles Material, das luftdurchlässig ist, abgeschlossen. Dadurch ist das an der Unterseite mit einem Luftkammersystem versehene Fußbett zwar nicht mehr aus dem Schuh herausnehmbar, es kann jedoch in die als eine Schale ausgebildete Laufsohle ohne Verklebung eingelegt werden, so daß die Flexibilität und Atmungsaktivität in Verbindung mit einer kostengünstigen Herstellung auch nach einem Befestigen des Schuhoberteils an der Laufsohle ebenfalls realisiert ist.The shoe sole system according to the invention can also be used for strobed shoes. In the case of stroked shoes, however, the upper material of the shoe is closed down towards the sole area by a textile material that is permeable to air. As a result, the footbed, which is provided with an air chamber system on the underside, can no longer be removed from the shoe, but it can be inserted into the outsole, which is designed as a shell, without gluing, so that the flexibility and breathability in connection with an inexpensive production also after fastening the upper of the shoe on the outsole is also realized.

In Fig. 1 ist eine Ansicht des erfindungsgemäßen Schuhsohlensystems dargestellt, bei dem das Fußbett 2, das fußformgerecht an seiner der Schuhinnenseite zugewandten Seite ausgebildet ist und an seiner Unterseite in einstückiger Herstellungsart ein aus einer Vielzahl von Kammern 3 bestehendes Luftkammersystem ausgebildet hat, in die die als Schale ausgebildete Schuhsohle bzw. Laufsohle 1 einlegbar ist. Eine derartige Gestaltung vereinfacht die Herstellung der Laufsohle deutlich und erhöht darüber hinaus die Flexibilität des Schuhsohlensystems, da das Luftkammersystem keine direkte Verbindung zu der eigentlichen Laufsohle 1 des Schuhs mehr hat. Somit bleibt die gesamte Flexibilität der Laufsohle voll erhalten, wohingegen bei Laufsohlen des Standes der Technik, bei denen die einzelnen gewichtsreduzierenden Hohlräume in einstückiger Herstellungsart Bestandteil der Laufsohle 1 sind, wobei durch die die einzelnen Hohlräume trennenden Stege eine zusätzliche Versteifung auftritt.In Fig. 1 is a view of the shoe sole system according to the invention is shown, in which the footbed 2, which is designed according to the shape of the foot on its side facing the inside of the shoe and on its underside in one-piece production, has formed an air chamber system consisting of a plurality of chambers 3 into which the shoe sole or outsole 1 designed as a shell can be inserted. Such a design significantly simplifies the production of the outsole and also increases the flexibility of the shoe sole system, since the air chamber system no longer has a direct connection to the actual outsole 1 of the shoe. The entire flexibility of the outsole is thus fully retained, whereas in the case of prior art outsoles in which the individual weight-reducing cavities are an integral part of the outsole 1, the webs separating the individual cavities providing additional stiffening.

Durch entsprechende Kanäle sind die einzelnen Kammern untereinander verbunden, so daß beim Gehen das erfindungsgemäße Schuhsohlensystem eine Mehrfachfunktion ausführen kann.The individual chambers are connected to one another by appropriate channels, so that the shoe sole system according to the invention can perform a multiple function when walking.

Zum einen führt der beim Gehen ausgeübte Druck des Fußes auf das Schuhsohlensystem während des Bewegungsablaufes des Fußes, d.h. beim Abrollen des Fußes, an den Druckstellen zu einem Komprimieren der Luft in den jeweiligen Kammern, und dadurch wird die Luft durch die Luftkanäle in die Kammern ohne Druckbelastung gedrückt. In diesen zuletzt genannten Kammern entsteht dadurch ein erhöhter Druck, wodurch die dort enthaltene Luft durch das luftdurchlässige Material bzw. durch die im Fußbett befindlichen Luftkanäle 4, die eine Verbindung zwischen dem Schuhinneren und dem eigentlichen Luftkammersystem herstellen, gedrückt wird. Durch diese Luftzirkulation zwischen den flexiblen Luftkammern in der Sohle und dem Schuhinnenbereich, in dem sich der Fuß befindet, entsteht eine optimale Zirkulation, so daß ein angenehmes Schuhklima entsteht.On the one hand, the pressure exerted by the foot when walking leads to the shoe sole system during the movement of the foot, i.e. when the foot rolls, at the pressure points to compress the air in the respective chambers, and thereby the air is pressed through the air channels into the chambers without pressure load. As a result, an increased pressure is created in these last-mentioned chambers, as a result of which the air contained therein is pressed through the air-permeable material or through the air channels 4 located in the footbed, which create a connection between the interior of the shoe and the actual air chamber system. This air circulation between the flexible air chambers in the sole and the inside of the shoe in which the foot is located creates an optimal circulation, so that a pleasant shoe climate is created.

Da das Material, das die Wände der einzelnen Kammern des Luftkammersystems bildet, aus den Gründen der oben erwähnten Realisierung der Zirkulation der Luft elastisch ausgeführt ist, ergibt sich zum anderen neben der Zirkulation eine optimale Energierückgabe in Verbindung mit einer idealen Auftrittsdämpfung bei einem zusätzlich vorhandenen angenehmen Schuhklima.Since the material that forms the walls of the individual chambers of the air chamber system is made elastic for the reasons of the above-mentioned realization of the circulation of the air, on the other hand, besides the circulation, there is an optimal energy return in connection with an ideal damping of the appearance with an additional pleasant one Shoe climate.

Das erfindungsgemäße atmungsaktive Schuhsohlensystem realisiert somit ein leichtes ermüdungsarmes Gehen. Es ist für eine Vielzahl unterschiedlicher Schuhtypen, Arten und Größen einsetzbar. Kostenvorteile entstehen vor allen Dingen dadurch, daß die eigentliche Laufsohle sehr einfach und für verschiedene Schuhtypen typisiert hergestellt werden kann.The breathable shoe sole system according to the invention thus realizes easy, fatigue-free walking. It can be used for a variety of different shoe types, types and sizes. Cost advantages arise above all from the fact that the actual outsole is very can be easily manufactured and typed for different types of shoes.

Hohe Anforderungen an die Paßgenauigkeit des Fußbettes in die Laufsohle sind nicht erforderlich, da gerade die Flexibilität zwischen diesen beiden Teilen, d.h. dem Fußbett 2 und der Laufsohle 1, beibehalten werden soll.High demands on the accuracy of fit of the footbed in the outsole are not necessary, since it is precisely the flexibility between these two parts, i.e. the footbed 2 and the outsole 1, should be maintained.

In Fig. 2 ist ein Längsschnitt durch ein erfindungsgemäßes Schuhsohlensystem dargestellt. Sämtliche an der Unterseite des Fußbettes 2 angebrachte Luftkammern 3 sind in dem in die Laufsohle 1 eingelegten Zustand über die Kanäle 4 sowohl untereinander als auch eine gewisse Anzahl der Luftkammern 3 durch ebenfalls derartige Luftkanäle 4 mit dem Schuhinnenraum verbunden.2 shows a longitudinal section through a shoe sole system according to the invention. All of the air chambers 3 attached to the underside of the footbed 2 are connected in the state inserted into the outsole 1 via the channels 4 both to one another and to a certain number of air chambers 3 by air channels 4 of the same type and to the interior of the shoe.

Die erfindungsgemäße Mehrfachfunktion des Schuhsohlensystems ist auch realisierbar, wenn das Luftkammersystem teilweise an der Unterseite des Fußbette angebracht ist. Das Luftkammersystem kann dabei nur im Fersenbereich in Höhenrichtung geteilt sein, oder in Schuhlängsrichtung insgesamt geteilt sein, d.h. zum Teil an der Unterseite des Fußbettes 2 angebracht und z.T. in der Laufsohle 1 eingearbeitet sein.The multiple function of the shoe sole system according to the invention can also be implemented if the air chamber system is partially attached to the underside of the footbed. The air chamber system can only be divided in the height direction in the heel area, or can be divided overall in the longitudinal direction of the shoe, i.e. partly attached to the underside of the footbed 2 and partly be incorporated into the outsole 1.

In Fig. 3 ist ein Ausführungsbeispiel dargestellt, bei dem die Laufsohle an das Schuhoberteil geklebt wird. Das als Innensohle ausgeführte Fußbett 2 wird in eine ebenfalls schalenförmig ausgeführte Laufsohle 1 (eine herkömmliche TR-Sohle) eingesetzt, ohne mit dieser verklebt zu werden. Die Laufsohle trägt an ihren Innenseiten einen Kleberand 5, der im eingelegten Zustand der Innensohle ein Verrutschen derselben sichern, jedoch keine feste Verbindung zwischen Laufsohle und Innensohle herstellt. Das Schuhoberteil 6 wird nun an dem Kleberand 5 festgeklebt, so daß die Innensohle zwar nicht mehr herausnehmbar ist, z.B. bei gestrobelten Schuhen oder bei Schuhen mit Brandsohle, jedoch die volle Flexibilität und Atmungsaktivität erhalten bleibt. Ein derartiges System ist somit auch für Schuhe mit Brandsohlen einsetzbar, wenn die Brandsohle selbst derart perforiert ist, daß durch die Brandsohle hindurch Verbindungen zwischen dem Schuhinneren und dem Luftkammersystem hergestellt sind.In Fig. 3, an embodiment is shown in which the outsole is glued to the shoe upper. The footbed 2, which is designed as an insole, is inserted into a shell-shaped outsole 1 (a conventional TR sole) without being glued to it. The outsole has on its insides an adhesive edge 5 which, when the insole is inserted, ensures that the insole does not slip, but does not establish a firm connection between the outsole and the insole. The shoe upper 6 is now glued to the adhesive edge 5, so that the insole is no longer removable, for example in the case of strobed shoes or shoes with an insole, but the full flexibility and breathability is retained. Such a system can thus also be used for shoes with insoles if the insole itself is perforated in such a way that connections between the inside of the shoe and the air chamber system are made through the insole.

In den Fig. 4a, b, c sind verschiedene Luftkammersysteme im Vorfußbereich dargestellt. In Fig. 4a ist ein trapezförmiges Luftkammersystem dargestellt, das ebenfalls über entsprechende Kanäle eine Verbindung der einzelnen Kammern untereinander gewährleistet sowie durch eine ausreichende Anzahl von Luftkanälen in dem Fußbett Verbindungen zwischen dem Luftkammersystem im Vorfußbereich und damit im gesamten Schuhsohlensystem zum Schuhinneren gewährleistet.4a, b, c different air chamber systems are shown in the forefoot area. In Fig. 4a a trapezoidal air chamber system is shown, which also ensures a connection of the individual chambers to one another via corresponding channels and ensures connections between the air chamber system in the forefoot area and thus in the entire shoe sole system to the inside of the shoe by means of a sufficient number of air channels in the footbed.

In Fig. 4b sind durch wellenförmige Trennwände wellenförmige Luftkammern im Vorfußbereich gebildet, die insgesamt durch einen Längskanal miteinander verbunden sind.4b, undulating air chambers in the forefoot area are formed by undulating partition walls, which are connected to one another overall by a longitudinal channel.

Und schließlich ist in Fig. 4c ein Labyrinthsystem gezeigt, das neben einer hohen Flexibilität des eigentlichen Vorfußbereiches beim Abrollen des Fußes auch eine ausgezeichnete Luftzirkulation zwischen den einzelnen Abschnitten des Zirkulationssystems und damit einer Zirkulation zwischen dem Luftkammersystem und dem Schuhinneren über die in der Fußsohle angeordneten Luftkanäle 4 gewährleistet.And finally, a labyrinth system is shown in Fig. 4c, which in addition to a high flexibility of the actual forefoot area when the foot rolls, also an excellent air circulation between the individual sections of the circulation system and thus a circulation between the air chamber system and the inside of the shoe via the air channels arranged in the sole of the foot 4 guaranteed.

Das bevorzugte Luftkammersystem in dem Fersenbereich ist vorzugsweise ein Rechteckkammersystem.The preferred air chamber system in the heel area is preferably a rectangular chamber system.
