Description

Die Erfindung betrifft eine Sohle für Schuhe, bestehend aus wenigstens zwei im wesentlichen starren Teilen, die zumindest teilweise aus Holz oder Holzwerkstoffen bestehen und die im Ballenbereich flexibel miteinander verbunden sind, wobei in dem sich über die ganze Sohlenbreite erstreckenden Spalt zwischen den gegenüberliegenden Stirnflächen benachbarter, im wesentlichen starrer Teile ein Zwischenstück aus flexiblem Material und an der Unterseite der im wesentlichen starren Teile eine Laufsohle aus flexiblem Material vorgesehen sind. Die Laufsohle muß hiebei nicht unbedingt entlang der gesamten Unterseite der im wesentlichen starren Teile durchgehend verlaufen.The invention relates to a sole for shoes, consisting of at least two essentially rigid parts, which at least partially consist of wood or wooden materials and which are flexibly connected to one another in the ball area, wherein in the gap extending across the entire sole width between the opposite end faces of adjacent, essentially rigid parts, an intermediate piece made of flexible material and an outsole made of flexible material are provided on the underside of the essentially rigid parts. The outsole does not necessarily have to run continuously along the entire underside of the essentially rigid parts.

Sohlen aus Holz sind bereits bekannt. Diese Sohlen besitzen zahlreiche Vorteile, da sie den Fuß in orthopädisch günstiger Weise abstützen und kälteisolierend, temperaturregelnd und feuchtigkeitssaugend sind, so daß Holzsohlen hygienisch und angenehm zu tragen sind. Bei zur Gänze aus Holz bestehenden Sohlen ist jedoch deren Steifigkeit nachteilig, da sie der Abrollbewegung des Fußes beim Gehen hinderlich ist.Wooden soles are already known. These soles have numerous advantages because they support the foot in an orthopedically favorable manner and are cold-insulating, temperature-regulating and moisture-absorbent, so that wooden soles are hygienic and comfortable to wear. In the case of soles made entirely of wood, however, their rigidity is disadvantageous, since it hinders the rolling movement of the foot when walking.

Man hat daher bereits Sohlen vorgeschlagen, die aus zwei Holzteilen bestehen, die im Ballenbereich durch einen flexiblen Verbindungsteil miteinander verbunden sind. Dadurch wird die Sohle im Ballenbereich biegbar und elastisch und kann sich der Abrollbewegung des Fußes beim Gehen anpassen.Soles have therefore already been proposed which consist of two wooden parts which are connected to one another in the ball area by a flexible connecting part. This makes the sole flexible and elastic in the ball area and can adapt to the rolling movement of the foot when walking.

Insbesondere ist es auch bekannt, den flexiblen Verbindungsteil aus an die Holzteile direkt angeschäumtem Polyurethan zu bilden, wodurch eine sichere und feste Verbindung zwischen den Holzteilen und dem flexiblen Zwischenteil auf einfache Weise erzielt wird.In particular, it is also known to form the flexible connecting part from polyurethane directly foamed onto the wooden parts, as a result of which a secure and firm connection between the wooden parts and the flexible intermediate part is achieved in a simple manner.

Bei Sohlen, welche aus zwei aus Holz bestehenden Teilen bestehen, die im Ballenbereich durch einen biegsamen Zwischenteil aus Gummi miteinander verbunden sind, ist es auch bereits bekannt, die Unterseite im Bereich des Sohlenvorderteiles mit einem dünnen Laufsohlenbelag aus Gummi zu versehen.For soles, which consist of two parts made of wood, which are connected to each other in the ball area by a flexible intermediate part made of rubber, it is also known to provide the underside in the area of the sole front part with a thin rubber outsole covering.

Schließlich sind Sohlen bekannt, die aus mehreren miteinander verbundenen Schichten bestehen, beispielsweise aus mehreren miteinander durch Kleben verbundenen Holzschichten.Finally, soles are known which consist of a plurality of layers connected to one another, for example a plurality of layers of wood connected to one another by gluing.

Durch die vorliegende Erfindung soll die Aufgabe gelöst werden, eine Sohle einerseits so auszubilden, daß sie alle Vorteile einer Holzsohle besitzt, wobei sie weiters im Ballenbereich die gewünschte Biegsamkeit aufweist, wobei jedoch eine hervorragende elastische Abstützung des Fußes gewährleistet ist und störende Klappergeräusche, wie sie sonst bei Holzsohlen auftreten, selbst wenn sie an ihrer Unterseite mit einer dünnen Laufsohle versehen sind, mit Sicherheit vermieden werden. Die Erfindung löst diese Aufgabe dadurch, daß die in an sich bekannter Weise aus Schichten, die im wesentlichen parallel zur Lauffläche und/oder zur der Fußsohle zugewendeten Fläche verlaufen, aufgebauten im wesentlichen starren Teile eine Brandsohle bilden, bei welcher zumindest die der Fußsohle unmittelbar benachbarte Schicht aus Holz oder Holzwerkstoffen besteht, und an deren Unterseite eine Laufsohle befestigt ist, die aus einem geschäumten Kunststoff, vorzugsweise aus Polyurethan besteht, wobei die Dicke der Laufsohle - senkrecht zur Lauffläche gemessen - im Ballenbereich größer ist als die Dicke der im wesentlichen starren Teile. Dadurch, daß die der Fußsohle unmittelbar benachbarte Schicht aus Holz oder Holzwerkstoffen, wie beispielsweise Kork, besteht, wird sichergestellt, daß die Fußsohle auf dem Holz aufruht, wodurch die eingangs geschilderten Vorteile der Holzsohlen auch bei der erfindungsgemäßen Sohle auftreten. Die Biegsamkeit im Ballenbereich ist durch das Zwischenstück aus flexiblem Material gewährleistet. Die im wesentlichen starren Teile bilden jedoch bei der erfindungsgemäßen Sohle nur die Brandsohle, an deren Unterseite noch eine Laufsohle befestigt ist, die zumindest im Ballenbereich dicker ist als die Brandsohle und die aus einem geschäumten Kunststoff, also aus einem nachgiebigen, elastischen Material besteht, so daß trotz der orthopädisch günstigen Abstützung der einzelnen Fußpartien durch die im wesentlichen starren Teile eine weiche, nachgiebige Abstützung des Fußes in seiner Gesamtheit über die Laufsohle gegeben ist. Die Laufsohle kann sich hiebei auch lediglich über den Bereich des Sohlenvorderteiles erstrecken, in welchem Fall sie jedenfalls auch im Ballenbereich angeordnet ist.The object of the present invention is to achieve a sole on the one hand so that it has all the advantages of a wooden sole, and furthermore it has the desired flexibility in the ball area, but an excellent elastic support of the foot is ensured and annoying rattling noises, such as it does otherwise occur with wooden soles, even if they are provided with a thin outsole on their underside, can be avoided with certainty. The invention solves this problem in that the essentially rigid parts constructed in a manner known per se from layers which run essentially parallel to the tread and / or to the surface facing the sole of the foot form an insole in which at least that immediately adjacent to the sole of the foot Layer of wood or wood-based materials, and on the underside of which an outsole is attached, which is made of a foamed plastic, preferably polyurethane, the thickness of the outsole - measured perpendicular to the tread - in the ball area being greater than the thickness of the essentially rigid parts . Characterized in that the immediately adjacent layer of wood or wood materials, such as cork, is ensured that the sole of the foot rests on the wood, whereby the advantages of the wooden soles described above also occur in the sole according to the invention. The flexibility in the bale area is guaranteed by the intermediate piece made of flexible material. The essentially rigid parts, however, only form the insole in the sole according to the invention, to the underside of which an outsole is attached, which is thicker than the insole at least in the ball area and which consists of a foamed plastic, that is to say of a resilient, elastic material, so that despite the orthopedic support of the individual parts of the foot by the essentially rigid parts, there is a soft, resilient support of the foot in its entirety over the outsole. The outsole can also only extend over the area of the front part of the sole, in which case it is also arranged in the ball area.

Im einfachsten Fall können die im wesentlichen starren Teile aus Schichtholz bestehen. Die Schichten können hiebei zumindest teilweise aus Preßholz bestehen oder zumindest teilweise aus Kork bestehen. Hiebei kann auch Preßkork verwendet werden. Kork ist gleichfalls ein Holzwerkstoff, da er aus Baumrinde gebildet ist, weist also die Vorteile von Holz auf, wobei er jedoch zusätzlich noch eine gewisse Elastizität senkrecht zur Lauffläche gewährleistet. Bei Verwendung von Preßkork sind die Vorteile des Korkes gleichfalls gegeben, wobei jedoch ebenso wie bei Preßholz praktisch eine vollständige Ausnützung des vorhandenen Rohstoffes ermöglicht wird, also keine Abfälle entstehen.In the simplest case, the essentially rigid parts can consist of plywood. The layers can at least partially consist of pressed wood or at least partially consist of cork. Press cork can also be used. Cork is also a wood-based material, since it is made from tree bark, so it has the advantages of wood, although it also ensures a certain elasticity perpendicular to the tread. When using pressed cork, the advantages of cork are also given, however, as with pressed wood, practically complete utilization of the existing raw material is made possible, so that no waste is generated.

Außerdem können die Schichten erfindungsgemäß zumindest teilweise aus Leder oder Lederfaserwerkstoffen bestehen, aber auch aus Kunststoff, beispielsweise aus Hart-Polyurethan oder Polyvinylchlorid. Bei Verwendung von geschäumtem Kunststoff tritt der Vorteil auf, daß ebenso wie bei Holz eine sichere Verbindung zwischen den im wesentlichen starren Teilen und dem flexiblen Verbindungsteil sowie der vorzugsweise aus geschäumtem Polyurethan bestehenden Laufsohle durch Anformen oder durch Ankleben erzielt werden kann. Geschäumter Kunststoff weist nämlich eine Zellstruktur auf, deren Zellen an den Verbindungsflächen durch mechanische oder chemische Behandlung zumindest teilweise geöffnet werden können, so daß dann in diese Zellen beim Anformen das noch nicht ausgehärtete Material des Verbindungsteiles bzw. der Laufsohle oder beim Ankleben das noch nicht ausgehärtete Klebemittel eindringen kann und sich dort verfestigt, so daß eine sehr gute mechanische Verbindung zwischen den im wesentlichen starren Teilen und den flexiblen Verbindungsteilen sowie der Laufsohle hergestellt wird, welche auch großen Beanspruchungen standhält.In addition, the layers according to the invention can at least partially consist of leather or leather fiber materials, but also of plastic, for example of hard polyurethane or polyvinyl chloride. When using foamed plastic, there is the advantage that, just as with wood, a secure connection between the essentially rigid parts and the flexible connecting part and the outsole, which is preferably made of foamed polyurethane, can be achieved by molding or by gluing. Foamed plastic This is because it has a cell structure, the cells of which can be at least partially opened at the connecting surfaces by mechanical or chemical treatment, so that the non-hardened material of the connecting part or the outsole or the non-hardened adhesive penetrate into these cells during molding can and solidifies there, so that a very good mechanical connection between the essentially rigid parts and the flexible connecting parts and the outsole is made, which can withstand even heavy loads.

Die die einzelnen Schichten bildenden Werkstoffe können auch miteinander kombiniert werden. Bei Verwendung von Kunststoffen ist es vorteilhaft, im Kunststoff natürliche und/oder synthetische Füllstoffe vorzusehen, wodurch die Eigenschaften des Kunststoffes in Bezug auf das Tragegefühl des Benützers der Schuhe verbessert werden kann und die Sohle ein formschönes Aussehen erhält. Es können aber auch als Füllstoffe kleinste Bläschen vorgesehen sein, deren dünne Hülle aus elastischem Vinylidenchlorid-Copolymerisat besteht und deren hohler Kern ein Gas, vorzugsweise Luftenthält. Durch Verwendung derartiger Füllstoffe erhält der Kunststoff eine Zellstruktur, so daß die oben erwähnten Vorteile bei der Verbindung der im wesentlichen starren Teile mit dem flexiblen Verbindungsteil und der Laufsohle gleichfalls auftreten.The materials forming the individual layers can also be combined with one another. If plastics are used, it is advantageous to provide natural and / or synthetic fillers in the plastic, as a result of which the properties of the plastic can be improved in relation to the wearing comfort of the user of the shoes and the sole is given an elegant appearance. However, the smallest bubbles can also be provided as fillers, the thin shell of which consists of elastic vinylidene chloride copolymer and the hollow core of which contains a gas, preferably air. The use of such fillers gives the plastic a cell structure, so that the advantages mentioned above also occur when the essentially rigid parts are connected to the flexible connecting part and the outsole.

Der Spalt kann mit einem flexiblen Füllstück ausgefüllt sein, das zweckmäßig aus geschäumten Kunststoff, vorzugsweise aus Polyurethan, besteht.The gap can be filled with a flexible filler, which suitably consists of foamed plastic, preferably polyurethane.

Wie bereits erwähnt, können die Laufsohle und/oder das Zwischenstück an die im wesentlichen starren Teile angeschäumt oder angeklebt sein.As already mentioned, the outsole and / or the intermediate piece can be foamed or glued to the essentially rigid parts.

Die Zeichnung zeigt ein Ausführungsbeispiel der erfindungsgemäßen Schuhsohle.The drawing shows an embodiment of the shoe sole according to the invention.

Die Schuhsohle weist eine Brandsohle auf, die aus zwei im wesentlichen starren Teilen 1, 2 gebildet ist, an deren Unterseite 5 eine Laufsohle 3 befestigt ist. Der Spalt zwischen den im wesentlichen starren Teilen 1, 2 ist durch ein Zwischenstück 4 aus flexiblem Material ausgefüllt. Die der Fußsohle zugewendete Oberseite 6 der im wesentlichen starren Teile 1, 2 kann eine orthopädische Formgebung aufweisen. Die im wesentlichen starren Teile 1, 2 bestehen aus einzelnen Schichten 7, die etwa parallel zur Unterseite 5 bzw. Oberseite 6 verlaufen. Die Schichten können alle aus demselben Material bestehen, es ist jedoch auch möglich, die einzelnen Schichten 7 aus verschiedenen Materialien zu bilden. Die oberste Schicht besteht jedenfalls aus Holz oder Holzwerkstoffen, wie beispielsweise Kork, da Holz die eingangs erwähnten hervorragenden tragehygienischen Eigenschaften besitzt.The shoe sole has an insole, which is formed from two essentially rigid parts 1, 2, on the underside 5 of which an outsole 3 is attached. The gap between the essentially rigid parts 1, 2 is filled by an intermediate piece 4 made of flexible material. The upper side 6 of the essentially rigid parts 1, 2 facing the sole of the foot can have an orthopedic shape. The essentially rigid parts 1, 2 consist of individual layers 7 which run approximately parallel to the bottom 5 or top 6. The layers can all consist of the same material, but it is also possible to form the individual layers 7 from different materials. In any case, the top layer consists of wood or wood-based materials, such as cork, since wood has the excellent hygienic properties mentioned at the beginning.

Die Laufsohle 3 ist zumindest im Ballenbereich wesentlich dicker als die von den im wesentlichen starren Teilen 1, 2 gebildete Brandsohle. Dadurch wird eine gute elastische Abstützung des Fußes in seiner Gesamtheit gewährleistet.The outsole 3 is, at least in the ball area, much thicker than the insole formed by the essentially rigid parts 1, 2. This ensures good elastic support for the foot as a whole.

Bei der dargestellten Ausführungsform verlaufen die den Spalt, in dem sich das Zwischenstück 4 befindet, begrenzenden Stirnflächen gerade, der Spalt weist somit, in der Sohlenlängsrichtung gesehen, überall die gleiche Breite auf. Es kann jedoch auch die Anordnung so getroffen sein, daß die Breite des Spaltes - gemessen in der Sohlenlängsrichtung - in dem der Fußsohle benachbarten Randbereich, also im Bereich der Oberseite 6, und/oder in dem der Lauffläche benachbarten Randbereich, also im Bereich der Unterseite 5, größer ist als die kleinste Breite im dazwischenliegenden Mittelbereich. Eine solche Ausbildung weist den Vorteil auf, daß auch bei einer starken Abbiegung der Sohle im Ballenbereich der Verbindungsteil 4 nicht einreißt und sich auch nicht von den im wesentlichen starren Teilen 1, 2 ablöst, da in den Randbereichen, wo beim Abbiegen der Sohle die Dehnung bzw. Stauchung des Zwischenstückes am größten ist, für die Aufnahme der hiedurch auftretenden Spannungen mehr Material zur Verfügung steht und dadurch die spezifische Dehnung bzw. Stauchung geringer wird. Außerdem wird durch diese Ausbildung auch die Verbindungsfläche zwischen dem Zwischenstück 4 und den im wesentlichen starren Teilen 1, 2 größer.In the embodiment shown, the end faces delimiting the gap in which the intermediate piece 4 is located run straight, the gap thus, seen in the longitudinal direction of the sole, has the same width everywhere. However, the arrangement can also be such that the width of the gap - measured in the longitudinal direction of the sole - in the edge area adjacent to the sole of the foot, i.e. in the area of the upper side 6, and / or in the edge area adjacent to the tread, i.e. in the area of the underside 5, is larger than the smallest width in the middle region in between. Such a design has the advantage that even with a strong bend in the sole in the ball area, the connecting part 4 does not tear and does not become detached from the essentially rigid parts 1, 2, since in the edge areas, where when the sole is bent, the expansion or compression of the intermediate piece is greatest, more material is available for absorbing the stresses that occur, and as a result the specific elongation or compression is less. In addition, this design also increases the connecting area between the intermediate piece 4 and the essentially rigid parts 1, 2.

Bei einer solchen Ausführungsform gehen zweckmäßig die beiden Randbereiche des Spaltes abgerundet in den Mittelbereich über, so daß scharfe Kanten vermieden werden, in welchen beim Abbiegen große Zug- und Druckspannungen auftreten, die zu einer Zerstörung des Zwischenstückes 4 führen könnten. Zweckmäßig gehen die Randbereiche des Spaltes tangential in die Oberseite 6 über, wodurch keine Stufen an der Übergangsstelle entstehen, die als störend empfunden werden.In such an embodiment, the two edge areas of the gap merge rounded into the central area, so that sharp edges are avoided, in which large tensile and compressive stresses occur during bending, which could lead to destruction of the intermediate piece 4. The edge regions of the gap expediently merge tangentially into the upper side 6, as a result of which there are no steps at the transition point which are perceived as disturbing.

Wie ersichtlich, ist der Spalt zu einer im wesentlichen senkrecht zur Lauffläche 5 verlaufenden Mittelachse 8 und vorzugsweise auch zu einer auf diese Mittelachse 8 senkrecht stehenden, im wesentlichen in Sohlenlängsrichtung verlaufenden Achse 9 symmetrisch ausgebildet. Diese symmetrische Ausbildung ist zweckmäßig auch dann vorgesehen, wenn die Breite des Spaltes im Bereich der Unterseite 5 und im Bereich der Oberseite 6 größer ist als im dazwischen liegenden Mittelbereich.As can be seen, the gap is formed symmetrically with respect to a central axis 8 which runs essentially perpendicular to the tread 5 and preferably also to an axis 9 which is perpendicular to this central axis 8 and runs essentially in the longitudinal direction of the sole. This symmetrical design is expediently also provided if the width of the gap in the area of the underside 5 and in the area of the top 6 is greater than in the middle area lying in between.

Das Zwischenstück 4 kann aus verschiedenen flexiblen Materialien bestehen. Es kann beispielsweise von einem flexiblen Füllstück gebildet sein, das nach dem Befestigen der Laufsohle 3 im Spalt angeordnet wird. Selbstverständlich kann aber das Zwischenstück 4 aus demselben geschäumten Kunststoffmaterial wie die Laufsohle 3 gebildet sein, also beispielsweise aus geschäumtem Polyurethan bestehen, und gegebenenfalls auch einstückig mit der Laufsohle 3 ausgebildet sein.The intermediate piece 4 can consist of different flexible materials. It can be formed, for example, by a flexible filler, which is arranged in the gap after the outsole 3 has been fastened. Of course, however, the intermediate piece 4 can be formed from the same foamed plastic material as the outsole 3, that is to say, for example, consist of foamed polyurethane, and if appropriate can also be formed in one piece with the outsole 3.

Die Befestigung der Laufsohle 3 und des Zwischenstückes 4 an den im wesentlichen starren Teilen 1, 2 kann sowohl durch Kleben als auch durch Anschäumen erfolgen, wobei auch die Varianten möglich sind, daß ein Teil, also beispielsweise die Laufsohle 3 oder das Zwischenstück 4, angeklebt, der andere Teil, also beispielsweise das Zwischenstück 4 oder die Laufsohle 3, angeschäumt wird.The attachment of the outsole 3 and the intermediate piece 4 to the essentially rigid parts 1, 2 can be carried out both by gluing and by foaming, with the Variants are possible that one part, for example the outsole 3 or the intermediate piece 4, is glued on, the other part, for example the intermediate piece 4 or the outsole 3, is foamed.

Durch die Laufsohle 3 wird nicht nur eine elastische Abstützung der Fußsohle in seiner Gesamtheit erzielt, sondern die Laufsohle 3 bewirkt auch eine Verbindung der beiden im wesentlichen starren Teile 1, 2, so daß es nicht unbedingt erforderlich ist, daß auch das Zwischenstück 4 mit den den Spalt begrenzenden Stirnflächen der im wesentlichen starren Teile 1, 2 fest verbunden wird.The outsole 3 not only provides elastic support for the sole of the foot in its entirety, but the outsole 3 also brings about a connection of the two essentially rigid parts 1, 2, so that it is not absolutely necessary that the intermediate piece 4 with the the gap-defining end faces of the essentially rigid parts 1, 2 is firmly connected.

11. Sole as claimed in claim 1, characterized in that the gap is filled with a flexible filling piece (4).
12. Sole as claimed in claim 11, characterized in that the filling piece (4) consists of foamed synthetic plastics material, preferably of polyurethane.
13. Sole as claimed in claim 1, characterized in that the width of the gap is - as measured in longitudinal direction of the sole - greater in the marginal area located adjacent the foot sole and/or in the marginal area located adjacent the running surface than the smallest width within the center area located therebetween.
14. Sole as claimed in claim 13, characterized in that both marginal areas of the gap are passing into the center area along a rounded surface.
15. Sole as claimed in claim 13 and 14, characterized in that the marginal areas of the gap tangentially pass over into the sole surface (5, 6).
16. Sole as claimed in claim 13, 14 or 15, characterized in that the gap is substantially symmetric relative to a center axis (8) substantially normally extending relative to the running surface and preferably also relative to an axis (9) normally extending to said center axis (8) and substantially extending in longitudinal direction of the sole.
17. Sole as claimed in any of claims 1 to 16, characterized in that the running sole (3) and/or the intermediate part (4) is applied to the substantially rigid parts (1, 2) by foaming operation.
18. Sole as claimed in any of claims 1 to 17, characterized in that the running sole (3) and/or the intermediate part (4) is glued onto the substantially rigid parts (1, 2).
