Abstract

A shoe, in particular a sports shoe or remedial shoe, with a shoe sole with at least one insert part made of a honeycomb member made of elastic compressible material, the central axes of the gas-filled honeycomb cells running at least approximately perpendicularly to the plane of the sole, is to be improved in such a manner that on the one hand the absorption and on the other hand the restoring force of the shoe sole and thus the energy yield after relief of pressure on the shoe sole are considerably increased. This is achieved in that the honeycomb member (1) is designed as a shaped member which is final in its dimensions, in that the honeycomb cells (2, 2') are closed in a gastight manner at the circumference or edge (3) of the honeycomb member (1), in that the upper and the lower honeycomb-cell openings (2a, 2b) are closed in a gastight or at least approximately gastight manner and in that the honeycomb member(s) (1) is or are accommodated in the surrounding sole (5) and fixed there. <IMAGE>

Description

Die vorliegende Erfindung bezieht sich auf einen Schuh, insbesondere Sportschuh oder Rehabilitationsschuh, gemäß dem Oberbegriff des Anspruches 1.The present invention relates to a shoe, in particular a sports shoe or a rehabilitation shoe, according to the preamble of claim 1.

Aus der US-A- 4,485,568 ist eine Einlegesohle für einen Schuh bekannt, die eine Wabenstruktur aufweist. Die Oberseite dieser Einlegesohle besteht aus luftdurchlässigem Material und die Unterseite aus einer dünnen Kaschierung. Am umlaufenden Rand sind die Wabenzellen, die zwischen dem geschäumtem Polster (Oberseite) und der dünnen Kaschierung angebracht sind, wenigstens teilweise offen, da der Wabenkörper aus an den Wänden zusammengeklebten, gewellten bzw. mäanderförmigen Bändern hergestellt ist und anschließend gereckt wird, so daß Wabenzellen von langgestreckter Rechteckform entstehen. Derartige Wabenkörper besitzen infolge der offenen Rand-Wabenzellen zum Rand hin eine stark abfallende Dämpfung, so daß auch die Rückstellkraft eines derartigen Wabenkörpers in den Randbereichen fast gegen Null tendiert. Dies wird auch durch die am Rand zusammengefügte Ober- und Unterseite nicht günstig beeinflußt bzw. gar kompensiert. Für eine Einlegesohle ist dieses Ergebnis auch nicht sehr störend,weil die Form der Einlegesohle in der Regel etwa der Projektion des Fußes auf den Schuhboden entspricht und der Rand der Einlegesohle kaum noch zur Auflage des Fußes dient.From US-A-4,485,568 an insole for a shoe is known which has a honeycomb structure. The top of this insole is made of air-permeable material and the bottom of a thin lamination. At the circumferential edge, the honeycomb cells, which are attached between the foamed upholstery (top side) and the thin lamination, are at least partially open, since the honeycomb body is made of corrugated or meandering bands glued together on the walls and then stretched, so that honeycomb cells of elongated rectangular shape. Because of the open edge honeycomb cells, such honeycomb bodies have a strongly decreasing damping towards the edge, so that the restoring force of such a honeycomb body in the edge regions also tends to almost zero. This is not favorably influenced or even compensated for by the top and bottom joined together at the edge. For an insole, this result is also not very annoying because of the shape of the Insole usually corresponds approximately to the projection of the foot onto the shoe bottom and the edge of the insole hardly serves to support the foot.

Für derartige Einlegesohlen ist es grundsätzlich auch nicht nachteilig, daß die für eine Luftzirkulation und damit Belüftung des Innenschuhes vorgesehenen Belüftungsöffnungen einen Dämpfungseffekt der Einlegesohle verhindern, da eine Luftverdichtung in den einzelnen Wabenzellen praktisch ausgeschlossen wird. Dies ergibt sich insbesondere aus Spalte 4, Zeilen 18 bis 25 der US-A- 4,485,568.For such insoles, it is also fundamentally not disadvantageous that the ventilation openings provided for air circulation and thus ventilation of the inner shoe prevent a damping effect of the insole, since air compression in the individual honeycomb cells is practically excluded. This results in particular from column 4, lines 18 to 25 of US-A-4,485,568.

Mit der vorliegenden Erfindung soll ein Schuh, insbesondere Sportschuh oder Rehabilitationsschuh,mit einem Wabenkörper aus elastischem, kompressiblem Material so verbessert werden, daß einerseits die Dämpfung und andererseits die Rückstellkraft der Schuhsohle und damit der Energiegewinn nach der Druckentlastung der Schuhsohle deutlich erhöht werden.With the present invention, a shoe, in particular a sports shoe or rehabilitation shoe, with a honeycomb body made of elastic, compressible material is to be improved in such a way that on the one hand the cushioning and on the other hand the restoring force of the shoe sole and thus the energy gain after the pressure relief of the shoe sole are significantly increased.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.This object is achieved by the characterizing features of claim 1.

Durch die im Randbereich des fertigen Formkörpers geschlossenen Wabenzellen tritt eine deutliche Erhöhung der Rückstellkraft in diesem Randbereich des Wabenkörpers ein, so daß der innere Bereich des dämpfenden und Rückstellkräfte erzeugenden Wabenkörpers sogar weicher ist als dieser Randbereich. Dadurch wird der erwünschte hohe Energiegewinn gerade auch im Randbereich der Schuhsohle sichergestellt, was gleichzeitig einen Schutz gegen die gefürchtete Überpronation bzw. Übersupination darstellt. Außerdem wird durch die oben und unten gasdicht oder wenigstens annähernd gasdicht verschlossenen Wabenzellen eine sehr günstige Federcharakteristik mit einer höheren Rückstellkraft in sämtlichen Wabenzellen erhalten. Dies gilt insbesondere für den Fall, daß die einzelnen Wabenzellen mit einem Gasdruck gefüllt sind, der deutlich höher ist als der Atmosphärendruck. Aber auch bei Atmosphärendruck innerhalb der Wabenzellen bleibt dieser Vorteil im wesentlichen erhalten, wenn dafür gesorgt ist, daß die einzelnen Wabenzellen weitestgehend luft- oder gasdicht abgedichtet sind, d.h. daß Luft oder Gas höchstens in eventuell verbleibenden Randspalten zwischen den Wabenzellen und den die Ober- und Unterseiten abdeckenden Flächen, Folien oder Deckeln langsam und in geringer Menge entweichen und bei Entlastung auch wieder zurückfließen kann.The honeycomb cells closed in the edge region of the finished molded body significantly increase the restoring force in this edge region of the honeycomb body, so that the inner region of the damping and restoring force-producing honeycomb body is even softer than this edge region. This ensures the desired high energy gain, especially in the edge area of the shoe sole, which also provides protection against the dreaded overpronation or oversupination. In addition, a very favorable spring characteristic with a higher restoring force is obtained in all honeycomb cells by the honeycomb cells which are sealed gas-tight or at least approximately gas-tight at the top and bottom. This is especially true in the event that the individual Honeycomb cells are filled with a gas pressure that is significantly higher than the atmospheric pressure. But even at atmospheric pressure within the honeycomb cells, this advantage is essentially maintained if it is ensured that the individual honeycomb cells are largely sealed airtight or gas-tight, that is, that air or gas is at most in any remaining marginal gaps between the honeycomb cells and the upper and Surfaces, foils or lids covering the underside can escape slowly and in small quantities and can flow back again when the load is removed.

In Fig. 1 ist mit 1 ein Wabenkörper aus einem Spritzgußteil bezeichnet, der aus elastischem, kompressiblem Material, insbesondere Kunststoff, wie Polyurethan, Polyolefin, Polyäthylen, Polypropylen, Polybutan, Polyamid, Äthylen-Vinyl-Acetat oder dgl. besteht. Bei den vorbezeichneten Kunststoffen handelt es sich bevorzugt um kompakte, nicht geschäumte Kunststoffe. Die einzelnen Wabenzellen 2, 2' besitzen bevorzugt einen mehreckigen Querschnitt, vorzugsweise sechseckigen Querschnitt. Im Rahmen der Erfindung liegen aber auch Wabenzellen 2, 2' mit beispielsweise kreisförmigen, elliptischen oder anderen abgerundeten Querschnitten. Der Wabenkörper 1 besitzt einen umlaufenden Rand 3, der die Randzellen 2' der Wabenzellen 2 nach außen dicht, insbesondere gasdicht, abschließt.In Fig. 1, 1 denotes a honeycomb body made of an injection molded part, which consists of elastic, compressible material, in particular plastic, such as polyurethane, polyolefin, polyethylene, polypropylene, polybutane, polyamide, ethylene-vinyl acetate or the like. The aforementioned plastics are preferably compact, non-foamed plastics. The individual honeycomb cells 2, 2 'preferably have a polygonal cross section, preferably a hexagonal cross section. However, honeycomb cells 2, 2 'with, for example, circular, elliptical or other rounded cross sections are also within the scope of the invention. The honeycomb body 1 has a peripheral edge 3, which seals the edge cells 2 'of the honeycomb cells 2 from the outside, in particular gas-tight.

Der Wabenkörper 1 ist beispielsweise gemäß der Darstellung der linken Hälfte der Fig. 2 so hergestellt, daß zunächst die beiden Seiten der Wabenzellen 2 nach unten und nach oben offen sind und die Ober- und Unterseite 2a, 2b mit je einem Abdeckelement 4 gasdicht oder jedenfalls weitestgehend gasdicht verschlossen sind. Die Abdeckelemente 4 bestehen bevorzugt aus Folien- oder Plattenmaterial und weisen bevorzugt eine Dicke von 0,1 bis 1,5 mm auf. Sie sind insbesondere durch einen Kleb- oder Schweißprozeß mit den Wandoberflächen der wabenförmigen Zellen bzw. Randzellen 2, 2' verbunden.The honeycomb body 1 is made, for example, according to the representation of the left half of FIG. 2 so that first the two sides of the honeycomb cells 2 are open at the top and bottom and the top and bottom 2a, 2b, each with a cover element 4 gas-tight or in any case are largely sealed gas-tight. The cover elements 4 preferably consist of film or plate material and preferably have one Thickness from 0.1 to 1.5 mm. They are in particular connected to the wall surfaces of the honeycomb cells or edge cells 2, 2 'by an adhesive or welding process.

Gemäß der rechten Hälfte der Fig. 2 kann der Wabenkörper 1 beispielsweise im Spritzgußverfahren so hergestellt werden, daß die eine, beispielsweise die obere Seite bzw. Fläche der Wabenzellen 2 bzw. 2' geschlossen ist. Es ist dann lediglich noch die Unterseite der Wabenzellen 2, 2' mit einem Abdeckelement 4 zu verschließen.According to the right half of FIG. 2, the honeycomb body 1 can be produced, for example, by injection molding in such a way that one, for example the upper side or surface of the honeycomb cells 2 or 2 'is closed. It is then only necessary to close the underside of the honeycomb cells 2, 2 'with a cover element 4.

Die Dicke bzw. Höhe eines Wabenkörpers 1 beträgt bevorzugt 0,3 cm bis 1,5 cm, insbesondere 0,5 cm bis 1,0 cm und ist vorzugsweise über die gesamte Erstreckung des Wabenkörpers 1 konstant. Sie kann jedoch auch, beispielsweise einem Fersenkeil entsprechend, keilförmig nach vorn in Richtung der Schuhsohlenspitze sich verjüngend ausgebildet sein.The thickness or height of a honeycomb body 1 is preferably 0.3 cm to 1.5 cm, in particular 0.5 cm to 1.0 cm, and is preferably constant over the entire extent of the honeycomb body 1. However, it can also be tapered in the direction of the tip of the shoe sole, for example corresponding to a heel wedge.

Wie anhand der Fig. 3 und 4 dargestellt ist, ist der Wabenkörper 1 in einer Schuhsohle 5, die bevorzugt als Schalensohle ausgebildet ist, im zentralen Bereich 6 des Fersenbeins 7 als Einsatz vorgesehen. Der Wabenkörper 1 ist also seitlich überall von mindestens 1 cm bis 2 cm von der umlaufenden Außenkante 15 der Schuhsohle 5 entfernt. Zur Lagefixierung des Wabenkörpers 1 können innerhalb der Schuhsohle 5 Fixierelemente in Form von Rippen oder dgl. vorgesehen sein.As shown in FIGS. 3 and 4, the honeycomb body 1 is provided as an insert in a shoe sole 5, which is preferably designed as a shell sole, in the central region 6 of the heel bone 7. The honeycomb body 1 is therefore laterally everywhere at least 1 cm to 2 cm away from the circumferential outer edge 15 of the shoe sole 5. To fix the position of the honeycomb body 1, 5 fixing elements in the form of ribs or the like can be provided within the shoe sole.

Die in Fig. 3 dargestellte Anbringung des Wabenkörpers 1 im Bereich 6 des Fersenbeines 7 bietet den Vorteil, daß das Fersenbein 7 mit dem Wabenkörper 1 mittelbar oder unmittelbar in Kraftschluß gelangt, was zu einer guten Dämpfungswirkung und zu dem gewünschten Energiegewinn (Rückfederung) nach der Druckentlastung der Schuhsohle führt.The attachment of the honeycomb body 1 shown in FIG. 3 in the area 6 of the heel bone 7 offers the advantage that the heel bone 7 directly or indirectly engages with the honeycomb body 1, which leads to a good damping effect and to the desired energy gain (springback) after Pressure relief of the shoe sole leads.

Im Ausführungsbeispiel gemäß Fig. 4 besteht die Schuhsohle 5 aus einer abriebfesten Laufsohle 8, einer dämpfenden Zwischensohle 9 und einer Ober- oder Innensohle 10. Der Wabenkörper 1 ist in einer Aussparung 11 der Zwischensohle 9 vorgesehen.4, the shoe sole 5 consists of an abrasion-resistant outsole 8, a cushioning midsole 9 and an upper or inner sole 10. The honeycomb body 1 is provided in a recess 11 in the midsole 9.

Zusätzlich zu dem im Bereich 6 der Laufsohle 5 vorgesehenen Wabenkörper 1 kann auch im Bereich 12 (strichpunktierte Linie) des Großzehenballens oder im Bereich 13 (gestrichelte Linie) des Zehenballens oder auch im Bereich 14 (punktierte Linie) des Vorderfußes ein Wabenkörper 1 gemäß der erfindungsgemäßen Ausgestaltung vorgesehen sein, wie anhand der Fig. 3 näher verdeutlicht ist. Dadurch erhält man auch in diesen Sohlenbereichen gute Dämpfungs- und Rückfedereigenschaften, was sowohl auf die Wabenstruktur als auch auf die Gasfederung der gasdichten bzw. weitestgehend gasdichten Wabenzellen 2, 2' zurückzuführen ist.In addition to the honeycomb body 1 provided in the area 6 of the outsole 5, a honeycomb body 1 according to the invention can also be located in the area 12 (dash-dotted line) of the big toe ball or in the area 13 (dashed line) of the toe ball or also in the area 14 (dotted line) of the forefoot Embodiment can be provided, as is illustrated in more detail with reference to FIG. 3. As a result, good damping and resilience properties are obtained in these sole areas, which is due both to the honeycomb structure and to the gas suspension of the gas-tight or largely gas-tight honeycomb cells 2, 2 '.

Zur Erzielung bestimmter Dämpfungs- und Rückstelleigenschaften kann der Gasdruck in den Wabenzellen 2, 2' größer sein als der Atmosphärendruck und daher beispielsweise zwischen 1000 hPa und 3000 hPa, insbesondere 2500 hPa, betragen.To achieve certain damping and resetting properties, the gas pressure in the honeycomb cells 2, 2 'can be greater than the atmospheric pressure and therefore, for example, between 1000 hPa and 3000 hPa, in particular 2500 hPa.

Desweiteren können die Dämpfungs- und Rückstelleigenschaften des Wabenkörpers 1 durch die Dicke der Wabenwände 16 bestimmt bzw. mitbestimmt werden. Insbesondere ist es möglich, Wabenwände 16 in verschiedenen Bereichen des Wabenkörpers 1 unterschiedlich dick auszubilden, wie beispielsweise anhand der Fig. 5 gezeigt ist.Furthermore, the damping and resetting properties of the honeycomb body 1 can be determined or co-determined by the thickness of the honeycomb walls 16. In particular, it is possible to design honeycomb walls 16 of different thickness in different areas of the honeycomb body 1, as is shown, for example, with reference to FIG. 5.

Eine weitere Variationsmöglichkeit erhält man beispielsweise bei Anwendung konischer Wabenzellen 2 bzw. 2' und/oder im Querschnitt konischer Wabenwände 16, wie anhand der Fig. 6 bis 8 veranschaulicht ist.Another possible variation is obtained, for example, when using conical honeycomb cells 2 or 2 ′ and / or honeycomb walls 16 with a conical cross section, as illustrated with reference to FIGS. 6 to 8.

Das oder die Abdeckelemente 4 können als Folie, Platte oder Deckel ausgebildet sein. Wie sich aus Fig. 9 ergibt, kann bei der Ausbildung der Abdeckelemente 4 als Deckel dieser mit an der Innenseite vorgesehenen Vorsprüngen 17 versehen sein, wobei die Vorsprünge 17 gegengleich zur Wabenstruktur des Wabenkörpers 1 geformt sind und in die Wabenzellen 2, 2' eingreifen. Durch Aufdrücken eines derartigen "Deckels" auf die offene(n) Seite(n) des Wabenkörpers 1 wird dieser durch Verrastung und/oder Verklemmung gasdicht jedenfalls aber weitestgehend gasdicht, verschlossen. Zusätzlich kann das Abdeckelement 4 an die Wabenstruktur aufgeklebt oder angeschweißt sein.The cover element (s) 4 can be designed as a film, plate or cover. As can be seen from FIG. 9, when the cover elements 4 are designed as lids, they can be provided with projections 17 provided on the inside, the projections 17 being shaped in the same way as the honeycomb structure of the honeycomb body 1 and engaging in the honeycomb cells 2, 2 '. By pressing such a "cover" onto the open side (s) of the honeycomb body 1, it is closed in a gas-tight manner, at least in most cases gas-tight, by latching and / or jamming. In addition, the cover element 4 can be glued or welded to the honeycomb structure.

Die Vorsprünge 17 sind zum besseren Einsetzen in die Wabenstruktur bevorzugt geneigt oder nach oben zu verjüngt, wie sich aus den Fig. 9 a bis 9c ergibt, oder die Vorsprünge 17 sind am Fuß leicht konisch ausgebildet, um einen insbesondere gasdichten Abschluß zu ermöglichen.For better insertion into the honeycomb structure, the projections 17 are preferably inclined or tapered upwards, as can be seen in FIGS. 9 a to 9 c, or the projections 17 are slightly conical on the foot in order to enable a gas-tight seal in particular.

Die Höhe der Vorsprünge 17 beträgt bevorzugt zwischen etwa 1 mm bis etwa 4 mm.The height of the projections 17 is preferably between approximately 1 mm to approximately 4 mm.

Bei Schuhsohlen 5, die einen Fersenkeil 18 (siehe Fig. 10, 11, 14) aufweisen, kann der Wabenkörper 1 innerhalb dieses Fersenkeils 18 untergebracht sein. In Fig. 10 ist der Wabenkörper 1 in einer Aussparung 11 eines Fersenkeiles 18 untergebracht und die Aussparung 11 ist unten beispielsweise zusätzlich durch eine Abdeckplatte 19 aus elastischem Material mit einer Shore-Härte zwischen 40 und 80 Shore-A abgedeckt. Die Abdeckplatte 19 ist vorzugsweise eingelegt, insbesondere eingeklemmt und/oder eingeklebt.In the case of shoe soles 5 which have a heel wedge 18 (see FIGS. 10, 11, 14), the honeycomb body 1 can be accommodated within this heel wedge 18. 10, the honeycomb body 1 is accommodated in a recess 11 in a heel wedge 18 and the recess 11 is additionally covered at the bottom, for example, by a cover plate 19 made of elastic material with a Shore hardness between 40 and 80 Shore-A. The cover plate 19 is preferably inserted, in particular clamped and / or glued.

Das Einsetzen eines Wabenkörpers 1 in einen Fersenkeil 18 oder in einen anderen Sohlenteil, beispielsweise in die Zwischensohle 9, kann auch von der Seite aus durch Einsetzen in einen Schlitz 20 oder in eine entsprechende seitliche Öffnung erfolgen, wie anhand der Fig. 11 gezeigt ist. Der Schlitz 20 bzw. die seitliche Öffnung ist nach außen wiederum mit einer Abdeckplatte 19 oder mit einem Abdeckstreifen verschlossen.The insertion of a honeycomb body 1 into a heel wedge 18 or into another sole part, for example into the midsole 9, can also be inserted from the side into a slot 20 or into a corresponding lateral opening, as shown in FIG. 11. The slot 20 or the lateral opening is again closed to the outside with a cover plate 19 or with a cover strip.

Bevorzugt kann der Wabenkörper 1 ganz vom Material des Fersenkeils 18 oder der Zwischensohle 9 umgeben sein, wie in Fig.12 dargestellt ist. Dies erfolgt bevorzugt durch einen Umformungsvorgang, beispielsweise durch Gießen oder Spritzgießen, bei dem der Wabenkörper 1 in eine Hohlform eingelegt und mit dem zu umspritzenden bzw. umgießenden Material umgeben wird.The honeycomb body 1 can preferably be completely surrounded by the material of the heel wedge 18 or the midsole 9, as shown in FIG. This is preferably done by a reshaping process, for example by casting or injection molding, in which the honeycomb body 1 is placed in a hollow mold and surrounded by the material to be overmolded or overmolded.

Gemäß einer weiteren, in Fig. 13 dargestellten, vorteilhaften Ausgestaltung der Erfindung kann als Schuhsohle 5 eine solche verwendet werden, deren Laufsohle 8, beispielsweise ab dem Gelenkbereich 21 zur Ferse zu nach unten wegklappbar und wieder mit dem übrigen Sohlenteil oder unmittelbar mit dem Schaftteil oder mit der Fersenkappe fest verbindbar ist. Die Zwischensohle 9 ist mit einer Aussparung 11 versehen, in die der Wabenkörper 1 einsetzbar ist. Nach dem Einsetzen des Wabenkörpers 1 wird der nach unten geklappte Laufsohlenteil wiederum nach oben geklappt und am übrigen Schuhteil bzw. an der Ferse befestigt.According to a further advantageous embodiment of the invention shown in FIG. 13, a shoe sole 5 can be used whose outsole 8 can be folded down, for example from the joint region 21 to the heel, and again with the rest of the sole part or directly with the shaft part or is firmly connected to the heel counter. The midsole 9 is provided with a recess 11 into which the honeycomb body 1 can be inserted. After inserting the honeycomb body 1, the outsole part folded down is again folded up and fastened to the rest of the shoe part or to the heel.

Eine ähnliche Ausführung mit geteilter Zwischensohle 9 ist aus Fig. 14 ersichtlich. Dort wird ein Fersenkeil 18 mit einem Wabenkörper 1 oder ein als Fersenkeil ausgebildeter Wabenkörper 1 zwischen die Trennebenen 22 und 23 der Zwischensohle 9 eingesetzt.A similar embodiment with a divided midsole 9 can be seen in FIG. 14. There, a heel wedge 18 with a honeycomb body 1 or a honeycomb body 1 designed as a heel wedge is inserted between the parting planes 22 and 23 of the midsole 9.

Anhand der Fig. 15 bis 18 werden nachfolgend weitere Einzelheiten eines Schuhes mit wegklappbarem hinteren Sohlenteil beschrieben.15 to 18, further details of a shoe with a foldable rear sole part are described below.

In Fig.15 ist mit 24 ein Schuh, insbesondere ein Sportschuh oder ein Schuh für medizinische Zwecke, vorzugsweise für Rehabilitationszwecke, bezeichnet. Obwohl nur ein Halbschuh dargestellt ist, kann dieser Schuh natürlich auch als Stiefel oder Schaftstiefel ausgebildet sein.In Fig. 15 there is a shoe, in particular a sports shoe or a shoe for medical purposes, preferably for rehabilitation purposes. Although only a low shoe is shown, this shoe can of course also be designed as a boot or ankle boot.

Der Schuh 24 besitzt eine Sohle, die aus einer Laufsohle 8, gegebenenfalls mit einer mit dieser fest verbundenen Dämpfungseinlage 25 und aus einer aus einer Schicht 26 und aus einer zweiten Schicht 27 bestehenden Zwischensohle 9 zusammengesetzt ist. Die Zwischensohle 9 kann auch einteilig oder mehr als zweiteilig ausgebildet sein. Laufsohle 8, Dämpfungseinlage 25 und Zwischensohle 9 bestehen aus den hierfür möglichen und üblichen, elastisch nachgiebigen Materialien, insbesondere aus volumenkompressiblen Materialien.The shoe 24 has a sole which is composed of an outsole 8, optionally with a damping insert 25 firmly connected to it, and an intermediate sole 9 consisting of a layer 26 and a second layer 27. The midsole 9 can also be made in one part or more than two parts. Outsole 8, cushioning insert 25 and midsole 9 consist of the possible and customary, resilient materials, in particular of volume-compressible materials.

Die Sohle ist so ausgebildet, daß die Laufsohle 8 über einen Großteil ihrer Längserstreckung, zumindest aber etwa ab dem Gelenkbereich 21 bis zum Schuhende, also bis zur Ferse, von der Zwischensohle 9 getrennt werden kann. Zwischensohle 9 und Laufsohle 8 bzw. deren Dämpfungseinlage 25 sind also in diesem Bereich nicht miteinander verklebt oder anderweitig dauerhaft fest miteinander verbunden.The sole is designed such that the outsole 8 can be separated from the midsole 9 over a large part of its longitudinal extent, but at least approximately from the joint region 21 to the end of the shoe, that is to the heel. Midsole 9 and outsole 8 or their cushioning insert 25 are therefore not glued to one another in this area or otherwise permanently connected to one another.

Die Befestigung der Laufsohle 8 erfolgt im Trennbereich durch an ihr angebrachte Befestigungsmittel 28, die mit entsprechenden an der Zwischensohle 9 und/oder am Obermaterial bzw. Schaft 20 und/oder auch an einer Fersenkappe 30 angebrachten Gegenstücken 31, kraft- oder formschlüssig verbindbar sind. Die lösbaren Verbindungsteile sind jeweils so ausgebildet, daß eine lösbare kraft- oder formschlüssige, mechanisch sichere Verbindung des trennbaren Teils der Laufsohle 8 mit dem übrigen Schuh gewährleistet ist.The outsole 8 is fastened in the separating area by means of fastening means 28 attached to it, which can be positively or positively connected to corresponding counterparts 31 attached to the midsole 9 and / or to the upper material or shaft 20 and / or also to a heel cap 30. The releasable connecting parts are each designed so that a releasable non-positive or positive, mechanically safe connection of the separable part of the outsole 8 with the rest of the shoe is ensured.

Beispielsweise erfolgt die lösbare Verbindung gemäß den Fig. 15 und 16 durch als nach oben ragende, als elastisch biegbare Laschen ausgebildete Befestigungsmittel, die am Rand der Laufsohle 8 verteilt angeordnet sind. Anstelle einzelner Laschen kann auch der ganze Rand der Laufsohle 8 schalenförmig nach oben ragen.For example, the detachable connection takes place according to the 15 and 16 by as upwardly projecting, designed as elastically bendable tabs fasteners which are arranged distributed on the edge of the outsole 8. Instead of individual tabs, the entire edge of the outsole 8 can also protrude upward in the form of a shell.

In den Laschen oder dem Rand der Laufsohle 8 sind eine oder mehrere Reihen von wenigstens zwei übereinander angeordneten Löchern 32 vorgesehen, in die als Stifte, beispielsweise als Steck- oder/und Raststifte ausgebildete Gegenstücke 31 der Zwischensohle 9 einsteckbar, einknöpfbar oder in sonstiger Weise verrastbar sein. Die Stifte 31 können nach Art von Nägeln ausgebildet und in die Zwischensohle 9 eingesteckt oder eingeformt oder an diese angeformt sein, also im letzteren Fall aus einem einzigen Bauteil mit der Zwischensohle 9 bestehen. In Fig. 15 sind die Raststifte 31 in die untersten Löcher 32 eingesteckt. In diesem Fall liegt die Laufsohle 8 hier mit ihrer Dämpfungseinlage 25 direkt auf der Zwischensohle 9 auf.In the tabs or the edge of the outsole 8, one or more rows of at least two holes 32 arranged one above the other are provided, into which counterparts 31 of the midsole 9 designed as pins, for example as plug-in and / or locking pins, can be inserted, buttoned in or locked in some other way be. The pins 31 can be designed in the manner of nails and inserted or molded into the midsole 9 or molded onto them, that is to say in the latter case they consist of a single component with the midsole 9. 15, the locking pins 31 are inserted into the lowermost holes 32. In this case, the outsole 8 lies here with its damping insert 25 directly on the midsole 9.

Die Fig. 16 zeigt eine Ausführung, in der die Raststifte 31 in den mittleren Löchern 32 stecken. Dadurch entsteht zwischen Laufsohle 8 bzw. deren Dämpfungseinlage 25 und der Zwischensohle 9 ein keilförmiger Zwischenraum 33. In diesem Zwischenraum 33 ist ein keilförmiger Wabenkörper 1 oder Fersenkeil 18 mit Wabenkörper 1 austauschbar einsetzbar bzw. eingesetzt (Fig. 16, 17 und 18).16 shows an embodiment in which the locking pins 31 are inserted in the central holes 32. This creates a wedge-shaped intermediate space 33 between the outsole 8 or its cushioning insert 25 and the midsole 9. In this intermediate space 33, a wedge-shaped honeycomb body 1 or heel wedge 18 with a honeycomb body 1 can be inserted or used interchangeably (FIGS. 16, 17 and 18).

Werden die Raststifte 31 in die obersten Löcher 32 der Befestigungsmittel 28 eingesteckt, so erweitert sich der Zwischenraum 33 und es kann ein entsprechend dickerer Fersenkeil 18 und/oder Wabenkörper 1 eingesetzt werden.If the locking pins 31 are inserted into the uppermost holes 32 of the fastening means 28, the intermediate space 33 widens and a correspondingly thicker heel wedge 18 and / or honeycomb body 1 can be used.

Es ist ohne weiteres erkennbar, daß dadurch eine Vielzahl von Möglichkeiten zur Anpassung der "Absatzhöhe" des Schuhes und/oder der Dämpfungscharakteristik der Laufsohle 8 im Bereich der Trennebene realisiert werden kann. Auch können unterschiedlich hohe Dämpfungsteile in beiden Schuhen oder die Verwendung eines Dämpfungsteiles nur in einem Schuh zum Ausgleich unterschiedlicher Beinlängen dienen.It is readily apparent that this provides a variety of options for adjusting the "heel height" of the shoe and / or the damping characteristic of the outsole 8 can be realized in the area of the parting plane. Damping parts of different heights can also be used in both shoes or the use of a damping part only in one shoe to compensate for different leg lengths.

Der Fersenkeil 18 und/oder der Wabenkörper 1 und die Zwischensohle 9 bestehen vorteilhaft aus elastischen, insbesondere geschäumten, vorzugsweise volumenkompressiblen Kunststoffen, vorzugsweise auf der Basis von Äthylen-Vinyl-Acetat.The heel wedge 18 and / or the honeycomb body 1 and the midsole 9 advantageously consist of elastic, in particular foamed, preferably volume-compressible plastics, preferably based on ethylene vinyl acetate.

Als Befestigungsmittel 28 und Gegenstücke 31 können viele Arten von Verbindungselementen verwendet werden. Beispielsweise können bei im Rand oder in den Laschen der Laufsohle 8 vorhandenen Löchern 32 Hilfsmittel, wie beispielsweise Stifte oder Bolzen durch die Löcher 32 in die Zwischensohle 9 eingesteckt oder eingeschraubt werden.Many types of connecting elements can be used as fastening means 28 and counterparts 31. For example, in the case of holes 32 in the edge or in the tabs of the outsole 8, aids such as, for example, pins or bolts can be inserted or screwed through the holes 32 into the midsole 9.

Anstelle der Verwendung von Löchern 32 einerseits und Stiften oder Bolzen andererseits können auch gemäß Fig. 17 an der Lasche 28 oder am Rand der Laufsohle 8 und an einer Fersenkappe 30 ineinanderrastbare Verzahnungen vorgesehen sein. Die Entrastung erfolgt durch seitliches Abziehen der Lasche.Instead of using holes 32 on the one hand and pins or bolts on the other hand, toothings which can be locked into one another can also be provided on the tab 28 or on the edge of the outsole 8 and on a heel cap 30, as shown in FIG. 17. The catch is released by pulling the tab off to the side.

Wie in Fig. 18 dargestellt, kann als Befestigungsmittel 28 und Gegenstück 31 auch ein Hebelverschluß vorgesehen sein. Die Art der einsetzbaren Verbindungselemente ist nicht auf die dargestellten und beschriebenen Ausführungsbeispiele beschränkt.As shown in FIG. 18, a lever lock can also be provided as the fastening means 28 and counterpart 31. The type of connecting elements that can be used is not limited to the exemplary embodiments shown and described.

Mit dieser Weiterbildung der Erfindung kann in einfacher Weise ein "Keilabsatz" unterschiedlicher Höhe und/oder Dämpfung auf verschiedenste Weise erhalten werden. Der Wabenkörper 1 kann insbesondere auch so gewählt werden, daß der Schuh 24 an das Gewicht der tragenden Person angepaßt ist.With this development of the invention, a "wedge heel" of different heights and / or damping can be obtained in a variety of ways. The Honeycomb body 1 can in particular also be chosen so that the shoe 24 is adapted to the weight of the person wearing it.

So hat es sich als zweckmäßig erwiesen, bei einem Personengewicht von bis zu 60 kg eine Härte des Wabenkörpers 1 von etwa 25 Shore A, bis zu 70 kg von etwa 35 Shore A und bis zu 80 kg und mehr von etwa 45 Shore A zu wählen.It has proven expedient to choose a hardness of the honeycomb body 1 of approximately 25 Shore A, up to 70 kg of approximately 35 Shore A and up to 80 kg and more of approximately 45 Shore A for a person weight of up to 60 kg .

Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung kann gemäß Fig. 19 in der Laufsohle 8 ein Fenster 34 unterhalb des zentralen Fersenbereiches 6, in dem sich in der Zwischensohle 9 oder in einem Fersenkeil 18 ein Wabenkörper 1 befindet, vorgesehen sein. Das Waben-Abdeckelement 4 oder eine Abdeckplatte 19 ist hierdurch von außen zugänglich und kann unmittelbar Bodenberührung erhalten. Das Abdeckelement 4 bzw. die Abdeckplatte 19 bestehen aus abriebfestem, elastischem Material, beispielsweise aus ungeschäumtem Polyurethan und weisen bevorzugt eine Shore-A-Härte zwischen 20 und 70 auf.According to a further advantageous embodiment of the invention, according to FIG. 19, a window 34 can be provided in the outsole 8 below the central heel area 6, in which a honeycomb body 1 is located in the midsole 9 or in a heel wedge 18. The honeycomb cover element 4 or a cover plate 19 is hereby accessible from the outside and can be brought into direct contact with the ground. The cover element 4 or the cover plate 19 consist of abrasion-resistant, elastic material, for example of non-foamed polyurethane, and preferably have a Shore A hardness between 20 and 70.

Wie aus Fig. 19 ferner ersichtlich, kann die Unterseite 35 des Abdeckelements 4 bzw. der Abdeckplatte 19 etwas nach innen vertieft in der Laufsohle 8 angeordnet sein, beispielsweise zwischen 1 mm bis 3 mm. Hierdurch wird eine bessere Dämpfung erzielt.As can also be seen from FIG. 19, the underside 35 of the cover element 4 or the cover plate 19 can be arranged slightly recessed inwards in the outsole 8, for example between 1 mm and 3 mm. This provides better damping.

Weiterhin kann das durch das Fenster 34 sichtbare Abdeckelement 4 bzw. die Abdeckplatte 19 aus durchsichtigem oder wenigstens durchscheinendem Material bestehen, so daß die Wabenstruktur erkennbar bzw. noch erkennbar ist. Dadurch ist es dem Fachmann möglich, beispielsweise anhand einer Tabelle den Dämpfungscharakter und die Rückstellkraft des zum Einsatz gelangenden Wabenkörpers zu bestimmen.Furthermore, the cover element 4 or the cover plate 19 visible through the window 34 can consist of transparent or at least translucent material, so that the honeycomb structure is recognizable or can still be recognized. This enables the person skilled in the art to determine the damping character and the restoring force of the honeycomb body used, for example on the basis of a table.

Die Form der Wabenzellen 2, 2' ist nicht auf die dargestellte und allgemein bekannte sechseckige Honigwabenform beschränkt. Vielmehr sind viele Möglichkeiten der Abwandlungen, angefangen von drei- oder mehr als sechseckigen Waben, auch runde oder ovale Waben verwendbar und entsprechend einsetzbar.The shape of the honeycomb cells 2, 2 'is not limited to the generally known hexagonal honeycomb shape shown. Rather, many possibilities of modifications, starting with triangular or more than hexagonal honeycombs, also round or oval honeycombs can be used and used accordingly.

Wichtig ist, daß der Wabenkörper 1 als Spritz-, Spritzguß- oder Gießteil während des Spritz-, Spritzguß- bzw. Gießverfahrens bereits seine endgültige Form erhält, wobei die Wabenzellen 2, 2' am Umfang bzw. Rand 3 des Wabenkörpers 1 bevorzugt bereits durch den Spritz-, Spritzguß- oder Gießvorgang gasdicht verschlossen sind.It is important that the honeycomb body 1 already receives its final shape as an injection, injection molding or casting part during the injection, injection molding or casting process, the honeycomb cells 2, 2 'on the circumference or edge 3 of the honeycomb body 1 preferably already through the injection, injection molding or casting process are sealed gas-tight.

Das Abdichten bzw. weitestgehende Abdichten der großflächigen Flachseiten des Wabenkörpers 1 gegen Gasaustritt erfolgt einseitig oder auch beidseitig durch gasdichte Folien, Deckel oder sonstige Abdeckelemente, insbesondere aus Kunststoff, mittels stoff-, form- oder kraftschlüssiger Verbindungen.The large flat surfaces of the honeycomb body 1 are sealed or largely sealed against gas leakage on one or both sides by means of gas-tight foils, lids or other covering elements, in particular made of plastic, by means of material, positive or non-positive connections.

Der für die vorliegende Erfindung wesentliche Gedanke, daß der Wabenkörper 1 als in seinen Abmessungen endgültiger Formkörper ausgebildet ist, gilt auch für eine abgewandelte Ausführungsform, wonach nur ein einziger einheitlicher Formkörper vorgesehen ist, der wenigstens annähernd der Form bzw. Kontur der Laufsohle 8 entspricht und mit dieser vorzugsweise ganzflächig verbunden ist. Bei dieser Ausgestaltung bildet der einheitliche, wabenförmige Formkörper praktisch die Zwischensohle bzw. ersetzt eine gesonderte Zwischensohle zwischen der eigentlichen Laufsohle und der Schuhinnensohle.The essential idea for the present invention that the honeycomb body 1 is designed as a final shaped body in its dimensions also applies to a modified embodiment, according to which only a single, uniform shaped body is provided which corresponds at least approximately to the shape or contour of the outsole 8 and is preferably connected to the entire surface. In this embodiment, the uniform, honeycomb shaped body practically forms the midsole or replaces a separate midsole between the actual outsole and the shoe insole.

Die Wabenzellen 2, 2' besitzen bei polygonaler Ausbildung einen Abstand einander gegenüberliegender Wände im Bereich von 3 mm bis 15 mm und bei runder bzw. elliptischer Ausbildung einen Durchmesser bzw. eine Ausdehnung der großen Ellipsenachse von 3 bis 15 mm.The honeycomb cells 2, 2 'have a spacing of opposing walls in the range of 3 mm to 15 mm in the case of a polygonal configuration and a diameter or an extension of the large ellipse axis of 3 to 15 mm in the case of a round or elliptical configuration.
