Abstract

To improve shock absorption and resiliency in a shoe sole, especially for athletic shoes with at least one sole section (15, 16, 50), while maintaining as little sole thickness as possible, and to be able to regulate flexural elasticity and, independently thereof, elasticity in the vertical direction, while maintaining a low sole weight, the invention proposes that the sole section (15, 16, 50) have channel-like recesses that run parallel to one another, at least in sub-sections, in top and bottom surfaces, with those situated on one side of the sole section (15, 16, 50) being staggered from those situated on the other side.

Description

Die Erfindung betrifft eine Schuhsohle, insbesondere für Sportschuhe, mit mindestens einem Sohlenteil, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a shoe sole, in particular for sports shoes, with at least one sole part, according to the preamble of claim 1.

Aus der DE 28 16 619 ist ein Sportschuh bekannt mit einer Sohle, die eine Laufsohle, eine Brandsohle, und einen sandwichartig dazwischen im Fersen- oder Absatzbereich angeordneten Zwischenschichtkörper umfaßt. Auf der Unter- und Oberseite des Zwischenschichtkörpers sind nutartige, gerade Vertiefungen angeordnet, die senkrecht zur Sohlenlängsrichtung verlaufen und von denen die auf der Oberseite vorgesehenen Vertiefungen gegenüber denen auf der Unterseite auf Lücke versetzt sind. Die in dem federnden und elastischen Zwischenschichtkörper vorgesehenen Vertiefungen sind zu den Seitenwänden des Zwischenschichtkörpers hin offen, um eine Zerstörung des Zwischenschichtkörpers durch eingeschlossene Luftkammern zu vermeiden. Die in den Vertiefungen befindliche Luft, die bei einer Komprimierung des Zwischenschichtkörpers ausströmt soll sich dabei als eine Art von Luftpuffer verhalten um Stoßenergie zu absorbieren und nach außen zu leiten.From DE 28 16 619 a sports shoe is known with a sole which comprises an outsole, an insole, and an intermediate layer body sandwiched therebetween in the heel or heel area. Groove-like, straight depressions are arranged on the bottom and top of the intermediate layer body, which run perpendicular to the longitudinal direction of the sole and of which the depressions provided on the top are offset from those on the bottom. The depressions provided in the resilient and elastic intermediate layer body are open towards the side walls of the intermediate layer body in order to avoid destruction of the intermediate layer body by enclosed air chambers. The air located in the depressions, which flows out when the intermediate layer body is compressed, is intended to behave as a type of air buffer in order to absorb impact energy and to conduct it to the outside.

Aus der EP 0 387 505 A1 ist eine Schuhsohle bekannt, bei der zur Verbesserung der Dämpfung und Rückstellkraft der Schuhsohle ein elastischer, kompressibler Wabenkörper in die Zwischensohle einsetzbar ist. Die einzelnen Wabenzellen sind gasdicht abgeschlossen, so daß der Wabenkörper als Gasfederung dient. Nachteilig ist hierbei, daß der Wabenkörper nur aufgrund seiner Materialelastizität und dem Knickverhalten seiner Wabenstege eine bestimmte, nicht veränderbare vertikale Kompressibilität aufweist und neben den Materialien für Lauf-, Zwischen- und Brandsohle ein weiteres Material für den Wabenkörper benötigt wird. Unter Umständen besteht die Sohle dann aus vier verschiedenen Materialien.A shoe sole is known from EP 0 387 505 A1, in which an elastic, compressible honeycomb body can be inserted into the midsole to improve the cushioning and restoring force of the shoe sole. The individual honeycomb cells are sealed gas-tight, so that the honeycomb body serves as a gas suspension. The disadvantage here is that the honeycomb body has a certain, unchangeable vertical compressibility only because of its material elasticity and the buckling behavior of its honeycomb webs, and in addition to the materials for the outsole, midsole and insole, a further material is required for the honeycomb body. The sole may then consist of four different materials.

Weiter ist aus der DE 33 05 160 A1 eine aus Lauf- und Brandsohle bestehende Schuhsohle eines Sportschuhs bekannt, bei der ein Staucheffekt auf die innen liegende Brandsohle beim Biegen der Schuhsohle vermieden wird. Dazu ist die Laufsohle rippenartig ausgestaltet, so daß sie ein fortlaufendes aus Wellenbergen und Wellentälern bestehendes Wellenband bildet, denn dadurch läßt sich die Laufsohle beim Biegen der Schuhsohle ziehharmonikaartig in Laufsohlenrichtung verlängern, womit eine Stauchung der Brandsohle verhindert wird. Die bekannte Schuhsohle hat keine über die Materialelastizität hinausgehenden Dämpfungseigenschaften in Vertikalrichtung und übt keine Rückstellkraft aus.Furthermore, from DE 33 05 160 A1 a shoe sole of a sports shoe consisting of an outsole and insole is known, in which a compression effect on the inner insole when bending the shoe sole is avoided. For this purpose, the outsole is rib-like, so that it forms a continuous wave band consisting of wave crests and wave troughs, because this allows the outsole to lengthen in accordion-like manner when the shoe sole is bent, thus preventing compression of the insole. The known shoe sole has no damping properties in the vertical direction that go beyond the material elasticity and does not exert a restoring force.

Ausgehend von diesem Stand der Technik ist es Aufgabe der Erfindung, unter Beibehaltung einer geringen Sohlendicke eine Verbesserung der Dämpfung und Rückstellkraft der Schuhsohle zu erreichen, sowie eine einstellbare Biegeelastizität und eine unabhängig davon einstellbare Elastizität in Vertikalrichtung bei geringem Gewicht der Sohle zu ermöglichen. Dabei soll eine möglichst geringe Anzahl verschiedener Materialien zum Einsatz kommen.Starting from this prior art, it is an object of the invention to achieve an improvement in the cushioning and restoring force of the shoe sole while maintaining a low sole thickness, and to enable adjustable bending elasticity and an independently adjustable elasticity in the vertical direction with a low weight of the sole. The smallest possible number of different materials should be used.

Diese Aufgabe wird erfindungsgemäß gelöst durch eine Schuhsohle mit den Merkmalen des Anspruchs 1.This object is achieved according to the invention by a shoe sole with the features of claim 1.

Durch die parallel verlaufenden und auf Lücke versetzten, nutartigen Vertiefungen auf Ober- und Unterseite des Sohlenteils ergibt sich eine gute Dämpfung und Rückstellkraft der Schuhsohle, ohne daß dadurch die Sohlendicke erhöht ist. Dies ist besonders wichtig bei Sportschuhen, da bei diesen ein guter Federungskomfort erwünscht ist, wobei die Sohlendicke möglichst gering zu halten ist. Eine große Sohlendicke würde die inneren und äußeren Fußgelenkbänder bei extremen Bewegungen stark belasten, da sich durch den erhöhten Abstand vom Boden zum Gelenk ein großer Hebelarm ergibt, wodurch bei abrupten seitlichen Bewegungen, wie sie beim Tennis oder Ballspielen auftreten, das Verletzungsrisiko an den Sprunggelenken erhöht ist.The parallel, gap-like, groove-like depressions on the top and bottom of the sole part result in good cushioning and restoring force of the shoe sole, without increasing the sole thickness. This is particularly important for sports shoes, since good cushioning comfort is desirable, with the sole thickness being kept as low as possible. A large sole thickness would put a heavy load on the inner and outer ankle ligaments during extreme movements, since the increased distance from the floor to the joint results in a large lever arm, which increases the risk of injury to the ankles during abrupt lateral movements, such as occur during tennis or ball games is.

Durch die Form des Querschnitts und die Tiefe der auf Lücke versetzten nutartigen Vertiefungen läßt sich die Elastizität des Sohlenteils in Vertikalrichtung einstellen. Dabei werden die elastischen Eigenschaften des Sohlenteils hauptsächlich durch Verbiegen des zwischen den auf Lücke versetzten Vertiefungen liegenden Sohlenmaterials bewirkt und nicht, wie bei herkömmlichen Schuhsohlen, durch einfaches Stauchen des Materials.The shape of the cross-section and the depth of the groove-like depressions set to a gap allow the elasticity of the sole part to be adjusted in the vertical direction. The elastic properties of the sole part are brought about mainly by bending the sole material lying between the recessed recesses and not, as in conventional shoe soles, by simply compressing the material.

Unabhängig von der Vertikalelastizität kann durch den in Sohlenebene bogenförmigen Verlauf der Vertiefungen die Biegeelastizität des Sohlenteils verändert werden.Regardless of the vertical elasticity, the bending elasticity of the sole part can be changed by the curved shape of the depressions in the plane of the sole.

Auf diese Weise läßt sich die Biegeelastizität der Schuhsohle sowohl in Sohlenlängsrichtung als auch in Sohlenquerrichtung unabhängig von der Elastizität in Vertikalrichtung einstellen, da die Elastizität in Vertikalrichtung, also die für die von der Schuhsohle bewirkte Dämpfung verantwortliche Druckelastizität, durch die Querschnittsform und die Größe der Vertiefungen beeinflußt werden kann, während die Biegeelastizität in Sohlenlängs- und Sohlenquerrichtung durch den mehr oder weniger stark gekrümmten bogenförmigen Verlauf beeinflußt wird.In this way, the flexural elasticity of the shoe sole can be adjusted both in the longitudinal direction of the sole and in the transverse direction of the sole, independently of the elasticity in the vertical direction, since the elasticity in the vertical direction, i.e. the pressure elasticity responsible for the cushioning caused by the shoe sole, due to the cross-sectional shape and the size of the depressions can be influenced, while the bending elasticity in the longitudinal and transverse direction of the sole is influenced by the more or less curved arcuate course.

Bei der Erfindung werden keine zusätzlichen Materialien verwendet.No additional materials are used in the invention.

Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.

Günstige Biegeeigenschaften ergeben sich aus den Ausgestaltungen nach Anspruch 2 oder 3.Favorable bending properties result from the configurations according to claim 2 or 3.

Nach Anspruch 4 können die Vertiefungen auch im Mittelfußbereich vorgesehen sein, wobei sie dann im wesentlichen in Sohlenlängsrichtung verlaufen, da in diesem Bereich eher eine Biegeelastizität um eine parallel zur Sohlenlängsrichtung liegende Achse gewünscht ist. Ebenso ergeben derartige Vertiefungen eine vorteilhafte Torsions-Weichheit im Mittelfußbereich.According to claim 4, the depressions can also be provided in the midfoot area, in which case they run essentially in the longitudinal direction of the sole, since in this area a bending elasticity about an axis lying parallel to the longitudinal direction of the sole is more desirable. Such depressions also result in advantageous torsional softness in the midfoot area.

In den Ausführungsformen nach den Ansprüchen 6 und 7 bildet das die Vertiefungen aufweisende Sohlenteil gleichzeitig die Laufsohle. Vorteilhafterweise sind dann die unterseitigen Vertiefungen Bestandteil des Laufsohlenprofils, wobei die Vertiefungen im Ballenbereich quer zur Sohlenlängsrichtung, im Mittelfußbereich längs und im Fersenbereich kreis- oder teilkreisförmig verlaufen. Dadurch erhält man die gewünschte Biegeelastizität im Ballenbereich quer und im Mittelfußbereich im wesentlichen parallel zur Sohlenlängsrichtung.In the embodiments according to claims 6 and 7, the sole part having the depressions simultaneously forms the outsole. The depressions on the underside are then advantageously part of the outsole profile, the depressions in the ball area extending transversely to the longitudinal direction of the sole, longitudinally in the midfoot area and circular or partially circular in the heel area. This gives the desired bending elasticity in the bale area transversely and in the midfoot area essentially parallel to the longitudinal direction of the sole.

Besonders bevorzugt ist eine Ausführungsform bei der das Sohlenteil eine zwischen einer gewöhnlichen Laufsohle und einer Brandsohle liegende Zwischensohle bildet.An embodiment is particularly preferred in which the sole part forms a midsole lying between an ordinary outsole and an insole.

Vorteilhaft ist die Zwischensohle im Randbereich vertiefungsfrei und die Laufsohle mit der Zwischensohle verklebt, wodurch die nutartigen Vertiefungen an der Unterseite der Zwischensohle zusätzlich als Gasfedern dienen.The midsole in the edge region is advantageously free of recesses and the outsole is glued to the midsole, as a result of which the groove-like depressions on the underside of the midsole also serve as gas springs.

In einer Ausführungsform der Erfindung können die Vertiefungen in einem Sohleneinsatzstück vorgesehen sein, das in das Sohlenteil einsetzbar ist. Dadurch ergibt sich die Möglichkeit, durch verschiedene Einsätze die Elastizität der Sohle zu bestimmen.In one embodiment of the invention, the depressions can be provided in a sole insert which can be inserted into the sole part. This makes it possible to determine the elasticity of the sole through various inserts.

Weiter ist es beispielsweise günstig die Vertiefungen auf der Oberseite schmal auszugestalten, damit die Brandsohle eine große Auflagefläche hat und so nicht in die Vertiefungen im Laufe der Zeit durch die Belastung mit dem Fuß eingedrückt wird.It is also advantageous, for example, to make the depressions narrow on the upper side, so that the insole has a large contact surface and is therefore not pressed into the depressions in the course of time by the load on the foot.

Mit den Ausführungsformen nach den Ansprüchen 15 bis 17 läßt sich die Vertikalelastizität des Sohlenteils unterschiedlich ausgestalten und einstellen. Durch eine größere Vertikalelastizität ergibt sich ein komfortableres Tragegefühl im Schuh durch Vermeidung von Druckstellen an der Fußsohle.With the embodiments according to claims 15 to 17, the vertical elasticity of the sole part can be designed and adjusted differently. The greater vertical elasticity results in a more comfortable fit in the shoe by avoiding pressure points on the sole of the foot.

Die Vertiefungen an der Oberseite können Teil eines Ventilationssystems sein, bei dem Luft aus der Atmosphäre von einem mit der Atmosphäre verbindbaren und durch Druckbelastung elastisch verformbaren Raum über Luftführungskanäle zu den oberseitigen Vertiefungen transportiert wird und von dort durch die luftdurchlässige Brandsohle in das Schuhinnere gelangt.The depressions on the upper side can be part of a ventilation system in which air from the atmosphere is transported from a space which can be connected to the atmosphere and can be elastically deformed by pressure loads, via air ducts to the upper depressions and from there through the air-permeable insole into the interior of the shoe.

Figur 1 zeigt einen Sportschuh 10 mit einer Schuhsohle 12 bestehend aus einer Laufsohle 14, einem Sohlenteil 15, das eine Zwischensohle 16 bildet und einer Brandsohle 18, wobei die Unterseite 20 der Zwischensohle 16 mit der Laufsohle 14 und die Oberseite 22 mit der Brandsohle 18 verbunden ist.1 shows a sports shoe 10 with a shoe sole 12 consisting of an outsole 14, a sole part 15 which forms a midsole 16 and an insole 18, the underside 20 of the midsole 16 being connected to the outsole 14 and the upper side 22 being connected to the insole 18 is.

Die Zwischensohle 16 weist im Ballenbereich 24 auf der Ober- und Unterseite 22, 20 zueinander parallel verlaufende nutartige Vertiefungen 26 und 28 auf, von denen die auf einer Seite 22 bzw. 20 der Zwischensohle 16 liegenden Vertiefungen 26 bzw. 28 zu denen auf der anderen Seite 20 bzw. 22 der Zwischensohle 16 liegenden Vertiefungen 28 bzw. 26 auf Lücke versetzt sind. Dadurch erhält die Zwischensohle 16 im Ballenbereich 24 im wesentlichen eine wellenartige Form.The midsole 16 has in the ball area 24 on the top and bottom 22, 20 mutually parallel groove-like depressions 26 and 28, of which the depressions 26 and 28 lying on one side 22 and 20 of the midsole 16 to those on the other Page 20 and 22 of the midsole 16 lying depressions 28 and 26 are offset. As a result, the midsole 16 in the ball area 24 is given an essentially wave-like shape.

Die Vertiefungen 26 und 28 verlaufen im wesentlichen quer zur Sohlenlängsrichtung. Die Vertiefungen 26 und 28 können jedoch auch im Mittelfußbereich 30 vorgesehen sein, wobei sie dann vorzugsweise in Sohlenlängsrichtung verlaufen.The depressions 26 and 28 run essentially transversely to the longitudinal direction of the sole. The depressions 26 and 28 can, however, also be provided in the midfoot region 30, in which case they then preferably run in the longitudinal direction of the sole.

Bei Druckbelastung der Zwischensohle 16 beim Aufsetzen des Fußes wird das zwischen den auf Lücke versetzten Vertiefungen 26 und 28 liegende Zwischensohlenmaterial verformt, so daß im Extremfall die Laufsohle 14 und die Brandsohle 18 mit Böden 32 der Vertiefungen 26 und 28 in Berührung kommen. Die Zwischensohle 16 wirkt im Ballenbereich 24, also im Bereich der Vertiefungen 26 und 28, wie eine Aneinanderreihung von Biegefedern, wobei vorteilhafterweise die Vertiefungen 26 der Oberseite 22 mit den auf Lücke versetzten Vertiefungen 28 der Unterseite 20 überlappen, wodurch auch gewährleistet ist, daß sich im gesamten Ballenbereich mindestens ein Luftpolster unter dem Fuß befindet.When the midsole 16 is subjected to pressure when the foot is placed on it, the midsole material located between the recesses 26 and 28 which are set to a gap is deformed, so that in extreme cases the outsole 14 and the insole 18 come into contact with the bottoms 32 of the recesses 26 and 28. The midsole 16 acts in the ball area 24, that is to say in the area of the depressions 26 and 28, like a series of spiral springs, the depressions 26 on the upper side 22 advantageously overlapping with the recessed depressions 28 on the underside 20, which also ensures that There is at least one air cushion under the foot in the entire bale area.

Dabei ist die Elastizität der Zwischensohle 16 abhängig von der Größe und Form der Querschnitte der Vertiefungen 26 und 28. Durch große Querschnitte wird die Sohle weicher, da bei Belastung weniger Material verformt wird, wohingegen kleinere Querschnitte eine größere Härte der Zwischensohle 16 bewirken. Aus diesem Grunde befinden sich die Vertiefungen 26 und 28 mit den größten Querschnitten in den Bereichen der Zwischensohle, in denen eine größere Weichheit der Schuhsohle 12 benötigt wird, beispielsweise in der Mitte des Ballenbereichs 24, wobei die Nuttiefe der Vertiefungen 26 und 28 etwa 30 % bis 70 % der Dicke der Zwischensohle 16 beträgt. Die Nuttiefe hängt auch von dem verwendeten Material ab. Bei Verwendung von weicherem Material beispielsweise müssen die Vertiefungen 26 und 28 flacher sein als bei einem härteren Material, um eine etwa gleiche Elastizität in vertikaler Richtung zu erhalten. Zum Zehenbereich bzw. Mittelfußbereich hin weisen die Vertiefungen einen kleineren Querschnitt auf.The elasticity of the midsole 16 is dependent on the size and shape of the cross sections of the depressions 26 and 28. The large cross sections make the sole softer, since less material is deformed under load, whereas smaller cross sections result in greater hardness of the midsole 16. For this reason, the depressions 26 and 28 with the largest cross sections are in the areas of the midsole in which the softness of the Shoe sole 12 is required, for example in the middle of the ball area 24, the groove depth of the depressions 26 and 28 being approximately 30% to 70% of the thickness of the midsole 16. The groove depth also depends on the material used. When using softer material, for example, the depressions 26 and 28 must be shallower than with a harder material in order to obtain approximately the same elasticity in the vertical direction. The depressions have a smaller cross-section towards the toe region or midfoot region.

Des weiteren kann die Härte und die Federelastizität in vertikaler Richtung der Zwischensohle 16 durch die Form der Querschnitte beeinflußt und damit eingestellt werden. Insbesondere können die Querschnitte rechteckig, kreissegmentförmig, dreieckig oder trapezförmig sein, wobei die Nutwände 34 der Vertiefungen 26 und 28 nach innen konvergieren. In Figur 1 sind die auf der Oberseite 22 der Zwischensohle 16 liegenden Vertiefungen 26 kreissegmentförmig und die an der Unterseite 20 liegenden Vertiefungen 28 trapezförmig.Furthermore, the hardness and the spring elasticity in the vertical direction of the midsole 16 can be influenced by the shape of the cross sections and can thus be adjusted. In particular, the cross sections can be rectangular, segmental, triangular or trapezoidal, the groove walls 34 of the depressions 26 and 28 converging inwards. In FIG. 1, the depressions 26 lying on the upper side 22 of the midsole 16 are in the form of a segment of a circle and the depressions 28 lying on the underside 20 are trapezoidal.

Es ist sinnvoll, die oberseitigen Vertiefungen 26 schmal auszugestalten, da sonst die weiche Brandsohle 18 im Laufe der Zeit durch die Belastung mit dem Fuß in die Vertiefungen 26 eingedrückt würde und sich so die Vertiefungen in der Brandsohle "abzeichnen". Dies würde ein Benutzer des Schuhs 10 als unangenehm empfinden. Die unterseitigen Vertiefungen 28 hingegen können breiter ausgeführt sein, da die Laufsohle 14 nicht so weich wie die Brandsohle 18 ist und sich somit nicht in die Vertiefungen eindrücken kann.It makes sense to make the recesses 26 on the top narrow, since otherwise the soft insole 18 would be pressed into the recesses 26 over time due to the load on the foot, and the recesses in the insole would thus “emerge”. A user of the shoe 10 would find this uncomfortable. The underside depressions 28, on the other hand, can be made wider, since the outsole 14 is not as soft as the insole 18 and therefore cannot press into the depressions.

Nach dem in Figur 2 gezeigten Ausführungsbeispiel verlaufen die Vertiefungen 26 und 28 geradlinig und quer zur Sohlenlängsrichtung. Dies führt zu einer großen Biegeelastizität der Zwischensohle, je nachdem wie groß die Querschnitte der Vertiefungen 26 und 28 gehalten sind, also wieviel Zwischensohlenmaterial zwischen den oberseitigen Vertiefungen 26 und den unterseitigen Vertiefungen 28 stehen bleibt. Ist eine geringere Biegeelastizität der Zwischensohle 16 erwünscht, können die Vertiefungen 26 und 28 bogenförmig verlaufen, wobei der Krümmungsmittelpunkt in Richtung des hinteren Schuhendes 36 liegt, wie in Fig. 3 gezeigt. Dies bewirkt dann eine Versteifung der Zwischensohle 16. Über den Krümmungsradius kann somit die Biegeelastizität der Zwischensohle 16 eingestellt werden und zwar getrennt von der durch die Querschnitte der Vertiefungen 26 und 28 einstellbaren Härte und Federelastizität in vertikaler Richtung.According to the embodiment shown in Figure 2, the depressions 26 and 28 are straight and transverse to the longitudinal direction of the sole. This leads to a great flexural elasticity of the midsole, depending on how large the cross sections of the depressions 26 and 28 are kept, ie how much midsole material remains between the upper-side depressions 26 and the lower-side depressions 28. If a lower bending elasticity of the midsole 16 is desired, the depressions 26 and 28 can run in an arc shape, the center of curvature being in the direction of the rear shoe end 36, as shown in FIG. 3. This then stiffens the midsole 16. The bending elasticity of the midsole 16 can thus be set via the radius of curvature, specifically separate from the hardness and spring elasticity in the vertical direction that can be adjusted by the cross sections of the depressions 26 and 28.

In einer anderen Ausgestaltung der Zwischensohle 16 bestehen die Vertiefungen 26 und 28 aus jeweils zwei geradlinigen Abschnitten, die in der Sohlenmitte zusammenlaufen und deren Schnittpunkt dem Sohlenvorderende zugeordnet ist. Auch dieser Verlauf bewirkt eine Versteifung und somit eine geringe Biegeelastizität der Zwischensohle 16.In another embodiment of the midsole 16, the depressions 26 and 28 each consist of two rectilinear sections which converge in the middle of the sole and whose intersection is assigned to the front end of the sole. This course also causes a stiffening and thus a low bending elasticity of the midsole 16.

Vorzugsweise ist die Zwischensohle 16 mit der Laufsohle 14 und der Brandsohle 18 verklebt. Wenn nun die Zwischensohle 16 auf ihrer Unterseite 20 im Randbereich 38 vertiefungsfrei ist, kann bei Druckbelastung der Zwischensohle 16 die Luft aus den Vertiefungen 28 nicht entweichen, wodurch diese eine Art Gasfeder bilden. Durch Einstellen eines bestimmten Luftdruckes in den Vertiefungen 28 ist die Härte und Elastizität der Gasfedern einstellbar.The midsole 16 is preferably glued to the outsole 14 and the insole 18. If the midsole 16 on its underside 20 is now free of recesses in the edge area 38, the air cannot escape from the depressions 28 when the midsole 16 is under pressure, as a result of which they form a type of gas spring. The hardness and elasticity of the gas springs can be adjusted by setting a specific air pressure in the depressions 28.

Ebenso ist es vorzugsweise vorgesehen, den Randbereich 38 auf der Oberseite vertiefungsfrei zu lassen. Die oberseitigen Vertiefungen 26 bilden dann gemäß dem Ausführungsbeispiel nach Figur 1 und 2 ein Teil eines Ventilationssystems, das im wesentlichen aus einer Ansaugöffnung 40, einem elastisch verformbaren Pumpenraum 42, einer Auslaßöffnung 44, Luftführungskanälen 48 und den oberseitigen Vertiefungen 26 besteht.Likewise, it is preferably provided to leave the edge area 38 on the upper side free of recesses. According to the exemplary embodiment according to FIGS. 1 and 2, the upper-side depressions 26 then form part of a ventilation system which essentially consists of a suction opening 40, an elastically deformable pump chamber 42, an outlet opening 44, air guide channels 48 and the upper-side depressions 26.

Beim Aufsetzen der Ferse wird die Ansaugöffnung 40 verschlossen und der elastisch verformbare Pumpenraum 42 durch die Druckbelastung der menschlichen Ferse komprimiert, wodurch die Luft über die Auslaßöffnung 44, die Luftführungskanäle 48 in die Vertiefungen 26 gepreßt wird. Damit die Luft in das Schuhinnere gelangen kann, weist die Brandsohle im Bereich der Vertiefungen 26 Löcher oder eine Perforation auf. Beim Anheben der Ferse wird die Ansaugöffnung 40 geöffnet und der Fersenbereich der Zwischensohle 16 entlastet, wodurch der komprimierte Pumpenraum 42 sich wieder erweitert und dabei Luft über die Ansaugöffnung 40 eingelassen wird. Dabei verhindert ein nicht dargestelltes Rückschlagventil eine Rückströmung der Luft.When placing the heel, the suction opening 40 is closed and the elastically deformable pump chamber 42 is compressed by the pressure load on the human heel, as a result of which the air is pressed into the recesses 26 via the outlet opening 44 and the air guide channels 48. So that the air can get inside the shoe, the insole has 26 holes or perforations in the area of the depressions. When the heel is raised, the suction opening 40 is opened and the heel region of the midsole 16 is relieved, as a result of which the compressed pump chamber 42 expands again and air is let in through the suction opening 40. A check valve (not shown) prevents the air from flowing back.

In einem weiteren Ausführungsbeispiel bildet das Sohlenteil 15, in dem die Vertiefungen 26 und 28 eingebracht sind, die Laufsohle 50. Die unterseitigen Vertiefungen 28 sind dann Bestandteil eines Laufsohlenprofils 52, das in Figur 4 in der Draufsicht dargestellt ist. In diesem Ausführungsbeispiel bilden die unterseitigen Vertiefungen 28 das gesamte Laufsohlenprofil 52. Dabei verlaufen die Vertiefungen 26 und 28 im Ballenbereich 24 quer zur Sohlenlängsrichtung, wodurch die gewünschte Biegeelastizität quer zur Sohlenlängsrichtung erreicht wird, im Mittelfußbereich 30 im wesentlichen parallel zur Längsrichtung, um die gewünschte Biegeelastizität parallel zur Längsrichtung zu erreichen, und im Fersenbereich ist ein kreis- und/oder teilkreisförmiger, konzentrischer Verlauf der Vertiefungen 26 und 28 vorgesehen, wodurch keine Richtung einer bevorzugten Biegeelastizität ausgezeichnet ist. In den jeweiligen Teilbereichen der Schuhsohle, nämlich Ballen-, Mittelfuß- und Fersenbereich verlaufen die Vertiefungen 26 und 28 parallel zueinander.In a further exemplary embodiment, the sole part 15, in which the depressions 26 and 28 are introduced, forms the outsole 50. The underside depressions 28 are then part of an outsole profile 52, which is shown in FIG. 4 in a top view. In this exemplary embodiment, the underside depressions 28 form the entire outsole profile 52. The depressions 26 and 28 in the ball area 24 run transversely to the longitudinal direction of the sole, as a result of which the desired bending elasticity is achieved transversely to the longitudinal direction of the sole, in the midfoot area 30 essentially parallel to the longitudinal direction by the desired bending elasticity To achieve parallel to the longitudinal direction, and in the heel area a circular and / or part-circular, concentric course of the recesses 26 and 28 is provided, whereby no direction of a preferred bending elasticity is excellent. In the respective partial areas of the shoe sole, namely the ball, midfoot and heel areas, the depressions 26 and 28 run parallel to one another.

Auch die Zwischensohle 16 kann den in Figur 4 dargestellten Verlauf der Vertiefungen 26 und 28 aufweisen.The midsole 16 can also have the course of the depressions 26 and 28 shown in FIG. 4.

In einem weiteren nicht dargestellten Ausführungsbeispiel kann das erfindungsgemäße Sohlenteil aus mehreren Lagen bestehen, wobei jede Lage die auf Lücke versetzten Vertiefungen auf ihrer Ober- und Unterseite aufweist. Wenn die Ausnehmungen auf den sich berührenden Seiten der jeweils benachbarten Lagen zueinander fluchten, weist das aus diesen übereinanderliegenden Lagen gebildete Sohlenteil dann im Querschnitt horizontale Reihen von parallel verlaufenden Ausnehmungen auf, wobei die Reihen gegeneinander auf Lücke versetzt sind.In a further exemplary embodiment, which is not shown, the sole part according to the invention can consist of several layers, each layer having the recessed recesses on its upper and lower sides. If the recesses on the contacting sides of the respectively adjacent layers are aligned with one another, the sole part formed from these layers lying one above the other then has horizontal rows of parallel recesses in cross section, the rows being offset from one another with a gap.

Vorzugsweise besteht das Sohlenteil 15 aus einem geschäumten Kunststoffmaterial, das beispielsweise Polyäthylen, Polypropylen, Polybutan, Polyamid, Polyurethan, Äthylen-Vinyl-Acetat oder Polyvinylchlorid sein kann.The sole part 15 preferably consists of a foamed plastic material, which can be, for example, polyethylene, polypropylene, polybutane, polyamide, polyurethane, ethylene-vinyl acetate or polyvinyl chloride.
