Definitions
- the invention relates to a shoe bottom, in particular for sports shoes, with the features according to the preamble of claim 1.
- Such weak points can be achieved by reducing the thickness of the shoe bottom or sole in the joint area, expediently leaving a central web running approximately in the longitudinal direction of the shoe (DE-AS 14 85 804), or recesses which protrude from the side edge of the shoe bottom can be provided, which are formed by a less rigid filling material are filled (DE-PS 943 996).
- the invention is therefore based on the object of providing a shoe bottom of the type described at the outset which ensures better guidance and support of the foot without impairing the desired torsional decoupling between the front and rear sole.
- the joint of the shoe bottom is thus stiffened against bending about an axis running transversely to the longitudinal direction of the shoe by stiffening means, the increased resistance to bending primarily affecting such a bending, which is known as the curvature of the
- the bottom of the shoe has a convex effect downwards, ie towards the running side.
- a tensile element as a stiffening means, which is anchored in the shoe longitudinal direction in the shoe bottom close to the running side thereof.
- This tensile element itself does not have to have any bending stiffness, since the stiffening of the shoe bottom is achieved due to the lack of or only very little stretchability of the tensile element and its arrangement below the "neutral bending fiber" of the shoe bottom.
- the flexural rigidity of the shoe bottom in the joint can therefore be controlled within wide limits by using such a traction means without the torsional rigidity of the shoe bottom in the joint being influenced thereby.
- Another significant advantage is that compared to stiffeners that have their own bending stiffness (e.g. steel hinge springs or the like), the stiffening can be kept considerably easier by the traction means, which is important for sports shoes. Because tensile and almost inextensible materials of high strength and very low weight are available, e.g. Metal wires, carbon and glass fibers, plastic wires and ribbon-like elements made from them.
- the weak points in the joint of the shoe bottom which reduce the torsional rigidity are transversely or obliquely protruding recesses in the joint of the shoe bottom which extend up to one in Extend the shoe longitudinal direction web of the shoe bottom.
- the web expediently runs approximately centrally between the side edges of the shoe bottom.
- the tensile element runs along this web. It can be embedded in the web near the underside - in the usual manufacture of the shoe base from plastic.
- the tensile element along the free lower surface of the web, whereby a wear sole attached to the front sole and the rear sole ensures that the tensile element does not come into direct contact with the ground. In this way, the tensile element is arranged very close to the running side of the shoe bottom.
- the stiffening means even if it is formed by the tensile element discussed above, can be embedded in its entire length in the shoe bottom, so that it is able to transmit stiffening forces over its entire length.
- this is not mandatory, since both rigid and only tensile stiffeners essentially require that both ends be fixed sufficiently firmly in the shoe bottom.
- anchoring inserts are expediently provided at the ends of the stiffening means, which are fastened in the shoe bottom, e.g. are directly embedded. These anchoring inserts are designed so that they can resist a shift in the longitudinal direction of the shoe, in accordance with the forces acting on them when the shoe bottom rolls off.
- the outsole shown in the drawings which forms a shoe bottom together with an insole, not shown, consists essentially of an midsole 1 made of foamed plastic, for example polyurethane, and a wear sole 2 arranged on the running side, which can be profiled.
- the outsole is divided into a front sole area 3 and a rear sole area 4 in the joint 5. The subdivision is achieved by two recesses 6, 7 projecting obliquely forward and inward from the outer edge of the sole or the inner edge of the sole, which - as can be seen in FIG. 3 - penetrate the shoe bottom by more than half its height.
- the thickness of the midsole 1 is left unchanged, so that a web 8 running approximately centrally in the longitudinal direction of the sole is thereby created.
- the front sole area 3 is torsionally “decoupled” from the rear sole area 4, ie the front sole area 3 can rotate relative to the rear sole area 4 about an axis running approximately along the web 8, which corresponds to the natural foot movement during the rolling process and therefore this promotes.
- the stiffening element 9 consists of tensile and low-stretch plastic wires 91 (e.g. made of nylon), which are combined in parallel next to one another to form a flat track, and of anchoring inserts 92 and 93 fastened to the ends of the plastic wires 91.
- the plastic wires 91 which have a diameter of 1, for example .5 mm, are firmly connected to the anchoring inserts 92, 93, which are also expediently made of plastic, for example by direct embedding in them.
- the plastic wires 91 can also be connected to one another along their length.
- the anchoring inserts 92, 93 are plate-shaped (see FIG. 2) and have lateral wings 94. Openings 95 are provided in the anchoring inserts 92, 93, through which the material of the midsole 1 can pass during the casting or molding process and embed the anchoring inserts.
- the wear sole has one in both sections, namely in the front sole area 3 and in the rear sole area 4 Interruption 10 in which the plastic wires 91 are exposed. This avoids the curvature of the band formed by the plastic wires 91 when the front sole area 3 is twisted relative to the rear sole area 4.
- the recess 10 is not necessary; it is entirely possible to completely cover the stiffening element 9 and in particular the plastic wires 91 by means of the wear sole 2 in order to protect them from damage.
- the Flexural rigidity of the outsole about a transverse axis running perpendicular to the web 8 can be controlled by the resistance to tensile expansion of the stiffening element 9. If the bending stiffness is to be increased, it can be considered to increase the number and thus the layer width of the plastic wires 91. In principle, a thickening of the plastic wires is also conceivable, but it should be avoided that a thickening increases the torsional rigidity of the shoe bottom in the joint.

Abstract
Description
Die Erfindung betrifft einen Schuhboden, insbesondere für Sportschuhe, mit den Merkmalen gemäß dem Oberbegriff des Anspruches 1.The invention relates to a shoe bottom, in particular for sports shoes, with the features according to the preamble of claim 1.
Aus der Biomechanik ist es bekannt, daß bei der natürlichen Abrollbewegung des Fusses zwischen dem Vorfuß und der Ferse etwa im Bereich der Keilbeine, d.h. über dem Gelenk des Schuhbodens, eine Verdrehung um eine etwa in Fußlängsrichtung verlaufende Achse stattfindet. Um dieser Verdrehung Rechnung zu tragen, ist es bekannt, im Gelenk des Schuhbodens gezielt Schwachstellen anzubringen, die eine Verdrehbarkeit des Vordersohlenbereiches gegenüber dem Hintersohlenbereich um eine etwa in Schuhlängsrichtung verlaufende Achse ermöglichen (DE-PS 804 901). Solche Schwachstellen können durch eine Verringerung der Schuhboden- oder Sohlendicke im Gelenkbereich erzielt sein, wobei zweckmässigerweise ein etwa in Schuhlängsrichtung verlaufender zentraler Steg verbleibt (DE-AS 14 85 804), oder es können vom Seitenrand des Schuhbodens her einspringende Ausnehmungen vorgesehen sein, die durch ein weniger steifes Füllmaterial ausgefüllt sind (DE-PS 943 996).From biomechanics it is known that during the natural rolling movement of the foot between the forefoot and the heel, in the area of the sphenoid bone, ie above the joint of the shoe bottom, there is a rotation about an axis running approximately in the longitudinal direction of the foot. In order to take this twist into account, it is known to deliberately create weak points in the joint of the shoe bottom, which enable the front sole area to be rotated relative to the rear sole area about an axis running approximately in the longitudinal direction of the shoe (DE-PS 804 901). Such weak points can be achieved by reducing the thickness of the shoe bottom or sole in the joint area, expediently leaving a central web running approximately in the longitudinal direction of the shoe (DE-AS 14 85 804), or recesses which protrude from the side edge of the shoe bottom can be provided, which are formed by a less rigid filling material are filled (DE-PS 943 996).
Die die Torsionssteifigkeit herabsetzenden Schwachstellen im Gelenk des Schuhbodens führen zwangsläufig auch zu einer Herabsetzung der Biegesteifigkeit des Schuhbodens um eine querverlaufende Achse. Dies ist nach der vorstehend angegebenen Lehre auch erwünscht, wobei lediglich vorgeschlagen wurde, durch eine Keillangsohle das Durchtreten des Schuhbodens im Gelenkbereich von Schuhen mit Absatz zu verhindern (vgl. DE-GBM 17 19 678), indem hierdurch dem Fuß auch im Gelenkbereich eine feste Auftrittsfläche geboten wird. Insbesondere bei Sportschuhen hat sich jedoch gezeigt, daß die prinzipiell erwünschte Verdreh- oder Verwringbarkeit von Vordersohle gegenüber Hintersohle zu einer unzureichenden Führung und Halterung des Fusses führt, wenn der Schuhboden im Gelenkbereich nicht nur torsionsnachgiebig, sondern auch biegeweich ist, weil hierdurch der Fuß im Bereich der Mittelfußgelenke zuviel Bewegungsfreiheit hat. Das macht sich als Mangel an seitlicher Stabilität insbesondere dann bemerkbar, wenn der Läufer mit dem Fuß auf Bahnunebenheiten tritt, was beim Wandern, bei Waldläufen, beim Jogging und dgl. in der Regel unvermeidbar ist.The weak points in the joint of the shoe bottom which reduce the torsional rigidity inevitably also lead to a reduction in the bending rigidity of the shoe bottom about a transverse axis. According to the teaching given above, this is also desirable, with the only suggestion being to prevent the bottom of the shoe from passing through in the joint area of shoes with a heel (cf. Performance space is offered. In sports shoes in particular, however, it has been shown that the principally desired rotatability or rotatability of the front sole compared to the rear sole leads to inadequate guidance and retention of the foot if the base of the shoe in the joint area is not only flexible, but also flexible, because this means that the foot is in the area the metatarsals have too much freedom of movement. This is particularly noticeable as a lack of lateral stability when the runner steps on uneven ground with his foot, which is generally unavoidable when hiking, running in the forest, jogging and the like.
Der Erfindung liegt daher die Aufgabe zugrunde, einen Schuhboden der eingangs beschriebenen Art zu schaffen, der ohne Beeinträchtigung der erwünschten torsionsmässigen Entkoppelung zwischen Vorder- und Hintersohle eine bessere Führung und Halterung des Fusses gewährleistet.The invention is therefore based on the object of providing a shoe bottom of the type described at the outset which ensures better guidance and support of the foot without impairing the desired torsional decoupling between the front and rear sole.
Erfindungsgemäß wird dies erreicht durch die Ausgestaltung gemäß dem Kennzeichen des Anspruches 1.According to the invention, this is achieved by the configuration according to the characterizing part of claim 1.
Erfindungsgemäß ist somit das Gelenk des Schuhbodens gegen eine Biegung um eine quer zur Schuhlängsrichtung verlaufende Achse durch Versteifungsmittel versteift, wobei die erhöhte Widerstandsfähigkeit gegen Biegung vor allem eine solche Biegung betrifft, die sich als Krümmung des Schuhbodens konvex nach unten, d.h. zur Laufseite hin, auswirkt.According to the invention, the joint of the shoe bottom is thus stiffened against bending about an axis running transversely to the longitudinal direction of the shoe by stiffening means, the increased resistance to bending primarily affecting such a bending, which is known as the curvature of the The bottom of the shoe has a convex effect downwards, ie towards the running side.
Mit besonderem Vorteil wird als Versteifungsmittel ein zugfestes Element eingesetzt, das in Schuhlängsrichtung verlaufend im Schuhboden nahe an dessen Laufseite verankert ist. Dieses zugfeste Element braucht selbst keinerlei Biegesteifigkeit zu haben, da die Versteifung des Schuhbodens aufgrund der fehlenden oder nur sehr geringen Dehnbarkeit des zugfesten Elements und dessen Anordnung unterhalb der "neutralen Biegefaser" des Schuhbodens erzielt wird. Das hat den bedeutsamen Vorteil, daß das zugfeste Element, das beispielsweise bandartig ausgebildet ist, keinerlei eigene Torsionssteifigkeit hat und daher die erwünschte Verdrehbarkeit der Vordersohle gegenüber der Hintersohle in keiner Weise beeinträchtigt. Die Biegesteifigkeit des Schuhbodens im Gelenk kann deshalb durch Verwendung eines solchen Zugmittels in weiten Grenzen gesteuert werden, ohne daß hierdurch die Torsionssteifigkeit des Schuhbodens im Gelenk beeinflusst wird. Ein weiterer wesentlicher Vorteil besteht darin, daß im Vergleich zu Versteifungsmitteln, die eine eigene Biegesteifigkeit besitzen (z.B. Stahlgelenkfedern od.dgl.) die Versteifung durch das Zugmittel erheblich leichter gehalten werden kann, was für Sportschuhe von Bedeutung ist. Denn es stehen zugfeste und nahezu undehnbare Materialien hoher Festigkeit und sehr geringen Gewichts zur Verfügung, z.b. Metalldrähte, Kohle- und Glasfasern, Kunststoffdrähte und bandartige Elemente, die aus solchen hergestellt sind.It is particularly advantageous to use a tensile element as a stiffening means, which is anchored in the shoe longitudinal direction in the shoe bottom close to the running side thereof. This tensile element itself does not have to have any bending stiffness, since the stiffening of the shoe bottom is achieved due to the lack of or only very little stretchability of the tensile element and its arrangement below the "neutral bending fiber" of the shoe bottom. This has the significant advantage that the tensile element, which is designed, for example, like a band, has no torsional rigidity of its own and therefore does not in any way impair the desired rotatability of the front sole relative to the rear sole. The flexural rigidity of the shoe bottom in the joint can therefore be controlled within wide limits by using such a traction means without the torsional rigidity of the shoe bottom in the joint being influenced thereby. Another significant advantage is that compared to stiffeners that have their own bending stiffness (e.g. steel hinge springs or the like), the stiffening can be kept considerably easier by the traction means, which is important for sports shoes. Because tensile and almost inextensible materials of high strength and very low weight are available, e.g. Metal wires, carbon and glass fibers, plastic wires and ribbon-like elements made from them.
In einer besonderen Ausgestaltung der Erfindung ist in bekannter Weise vorgesehen, daß die die Torsionssteifigkeit herabsetzenden Schwachstellen im Gelenk des Schuhbodens vom Rand her quer oder schräg (nach vorne oder hinten) einspringende Ausnehmungen sind, die sich bis zu einem in Schuhlängsrichtung verlaufenden Steg des Schuhbodens erstrecken. Der Steg verläuft zweckmässigerweise etwa mittig zwischen den seitlichen Schuhbodenrändern. Bei dieser Ausgestaltung ist vorgesehen, daß das zugfeste Element längs dieses Steges verläuft. Dabei kann es - bei der üblichen Herstellung des Schuhbodens aus Kunststoff - in den Steg nahe an dessen Unterseite eingebettet sein. Möglich ist aber auch die Anordnung des zugfesten Elements längs der freien Unterfläche des Steges, wobei durch eine auf der Vordersohle und der Hintersohle befestigte Verschleißsohle dafür gesorgt ist, daß das zugfeste Element nicht direkt in Bodenkontakt kommt. Auf diese Weise ist das zugfeste Element sehr nahe an der Laufseite des Schuhbodens angeordnet.In a special embodiment of the invention it is provided in a known manner that the weak points in the joint of the shoe bottom which reduce the torsional rigidity are transversely or obliquely protruding recesses in the joint of the shoe bottom which extend up to one in Extend the shoe longitudinal direction web of the shoe bottom. The web expediently runs approximately centrally between the side edges of the shoe bottom. In this embodiment it is provided that the tensile element runs along this web. It can be embedded in the web near the underside - in the usual manufacture of the shoe base from plastic. However, it is also possible to arrange the tensile element along the free lower surface of the web, whereby a wear sole attached to the front sole and the rear sole ensures that the tensile element does not come into direct contact with the ground. In this way, the tensile element is arranged very close to the running side of the shoe bottom.
Das Versteifungsmittel, auch wenn es durch das vorstehend besprochene zugfeste Element gebildet ist, kann auf seiner ganzen Länge im Schuhboden eingebettet sein, so daß es auf seiner ganzen Länge in der Lage ist, versteifend wirkende Kräfte zu übertragen. Dies ist jedoch nicht zwingend, da es sowohl bei biegesteifen als auch nur zugfesten Versteifungsmitteln im wesentlichen darauf ankommt, deren beide Enden ausreichend fest im Schuhboden zu fixieren. Aus diesem Grund sind zweckmässigerweise an den Enden des Versteifungsmittels Verankerungseinsätze vorgesehen, die im Schuhboden befestigt, z.B. direkt eingebettet sind. Diese Verankerungseinsätze sind so ausgelegt, daß sie sich einer Verlagerung in Schuhlängsrichtung, entsprechend den auf sie beim Abrollen des Schuhbodens einwirkenden Kräften, widersetzen können.The stiffening means, even if it is formed by the tensile element discussed above, can be embedded in its entire length in the shoe bottom, so that it is able to transmit stiffening forces over its entire length. However, this is not mandatory, since both rigid and only tensile stiffeners essentially require that both ends be fixed sufficiently firmly in the shoe bottom. For this reason, anchoring inserts are expediently provided at the ends of the stiffening means, which are fastened in the shoe bottom, e.g. are directly embedded. These anchoring inserts are designed so that they can resist a shift in the longitudinal direction of the shoe, in accordance with the forces acting on them when the shoe bottom rolls off.
Ein Ausführungsbeispiel der vorliegenden Erfindung ist nachfolgend anhand der beiliegenden Zeichnungen näher erläutert. In den Zeichnungen zeigen:
- Fig. 1 eine Untenansicht einer Laufsohle nach der Erfindung, teilweise aufgebrochen;
- Fig. 2 eine Seitenansicht der Laufsohle nach Fig. 1, teilweise geschnitten längs der Linie II-II in Fig. 1, und
- Fig. 3 eine Teil-Seitenansicht der Laufsohle gemäß Fig. 1, gesehen in Richtung des Pfeiles III.
- Figure 1 is a bottom view of an outsole according to the invention, partially broken away.
- Fig. 2 is a side view of the outsole of Fig. 1, partially sectioned along the line II-II in Fig. 1, and
- Fig. 3 is a partial side view of the outsole of FIG. 1, seen in the direction of arrow III.
Die in den Zeichnungen dargestellte Laufsohle, die zusammen mit einer nicht dargestellten Brandsohle einen Schuhboden bildet, besteht im wesentlichen aus einer Zwischensohle 1 aus geschäumtem Kunststoff, z.b. Polyurethan,und einer laufseitig angeordneten Verschleißsohle 2, die profiliert sein kann. Die Laufsohle ist im Gelenk 5 in einen Vordersohlenbereich 3 und einen Hintersohlenbereich 4 unterteilt. Die Unterteilung ist erzielt durch zwei vom Sohlenaußenrand bzw. Sohleninnenrand schräg nach vorne und innen einspringende Ausnehmungen 6, 7, die - wie aus Fig. 3 hervorgeht - den Schuhboden mehr als zur Hälfte seiner Höhe durchsetzen. Zwischen den einander zugewendeten Enden der Ausnehmungen 6 und 7 ist die Zwischensohle 1 in ihrer Dicke unverändert belassen, so daß dadurch ein etwa mittig in Sohlenlängsrichtung verlaufender Steg 8 geschaffen ist. Durch die Ausnehmungen 6, 7 wird der Vordersohlenbereich 3 gegenüber dem Hintersohlenbereich 4 torsionsmässig "entkoppelt", d.h. der Vordersohlenbereich 3 kann um eine etwa längs des Steges 8 verlaufende Achse sich gegenüber dem Hintersohlenbereich 4 verdrehen, was der natürlichen Fußbewegung beim Abrollvorgang entspricht und diesen daher fördert.The outsole shown in the drawings, which forms a shoe bottom together with an insole, not shown, consists essentially of an midsole 1 made of foamed plastic, for example polyurethane, and a wear sole 2 arranged on the running side, which can be profiled. The outsole is divided into a front
In die Zwischensohle 1 ist ein im Ganzen mit 9 bezeichnetes Versteifungselement eingebettet. Das Versteifungselement 9 besteht aus zugfesten und dehnungsarmen Kunststoffdrähten 91 (z.B. aus Nylon), die parallel nebeneinander zu einer ebenen Bahn vereinigt sind, sowie aus an den Enden der Kunststoffdrähte 91 befestigten Verankerungseinsätzen 92 und 93. Die Kunststoffdrähte 91, die beispielsweise einen Durchmesser von 1,5 mm aufweisen, sind mit den zweckmässigerweise ebenfalls aus Kunststoff hergestellten Verankerungseinsätzen 92, 93 fest verbunden, beispielsweise durch direktes Einbetten in diese. Die Kunststoffdrähte 91 können miteinander auf ihrer Länge ebenfalls verbunden sein. Die Verankerungseinsätze 92, 93 sind plattenförmig (vgl. Fig. 2) und weisen seitliche Flügel 94 auf. In den Verankerungseinsätzen 92, 93 sind Durchbrüche 95 vorgesehen, durch welche das Material der Zwischensohle 1 beim Gieß- oder Formvorgang hindurchtreten und die Verankerungseinsätze einbetten kann.In the midsole 1, a stiffening element, generally designated 9, is embedded. The stiffening element 9 consists of tensile and low-stretch plastic wires 91 (e.g. made of nylon), which are combined in parallel next to one another to form a flat track, and of anchoring
Wie aus Fig. 2 hervorgeht, liegt die Unterseite des Steges 8, längs der sich die Kunststoffdrähte 91 erstrecken, oberhalb der Laufseite der Verschleißsohle 2. In dem gezeigten Ausführungsbeispiel weist die Verschleißsohle in beiden Abschnitten, nämlich im Vordersohlenbereich 3 und im Hintersohlenbereich 4, eine Unterbrechung 10 auf, in der die Kunststoffdrähte 91 freiliegen. Hierdurch wird die Behinderung einer Verwölbung des durch die Kunststoffdrähte 91 gebildeten Bandes bei einer Torsion des Vordersohlenbereiches 3 gegenüber dem Hintersohlenbereich 4 vermieden. Die Ausnehmung 10 ist jedoch nicht erforderlich; es ist durchaus möglich, mittels der Verschleißsohle 2 das Versteifungselement 9 und insbesondere die Kunststoffdrähte 91 völlig zu bedecken, um diese vor Beschädigungen zu schützen.As can be seen from FIG. 2, the underside of the
Aus der vorstehenden Erläuterung ergibt sich, daß die Biegesteifigkeit der Laufsohle um eine senkrecht zu dem Steg 8 verlaufende Querachse durch die Widerstandsfähigkeit gegen Zugdehnung des Versteifungselementes 9 gesteuert werden kann. Soll die Biegesteifigkeit erhöht werden, so kann daran gedacht werden, die Anzahl und damit die Lagenbreite der Kunststoffdrähte 91 zu erhöhen. Prinzipiell ist auch eine Verdickung der Kunststoffdrähte denkbar, jedoch soll vermieden werden, daß durch eine Verdickung die Torsionssteifigkeit des Schuhbodens im Gelenk erhöht wird.From the above explanation it follows that the Flexural rigidity of the outsole about a transverse axis running perpendicular to the
Es versteht sich, daß anstelle der im Ausführungsbeispiel beschriebenen Kunststoffdrähte 91 auch andere zugfeste Versteifungsmittel eingesetzt werden können. So ist daran zu denken, mittels der Verankerungseinsätze 92, 93 ein Netz, Geflecht oder Gewebe aus Glas- oder Kohlefasern vorzusehen, das bandförmig ausgebildet und in ähnlicher Weise in der Sohle eingebettet ist, wie dies vorstehend erläutert ist. Durch Wahl der Bandbreite eines solchen Gewebes kann die Zugfestigkeit und damit die resultierende Biegesteifigkeit in weiten Grenzen gesteuert werden, ohne das Gewicht des Schuhbodens merklich zu beeinflussen. Im Rahmen der Erfindung liegt jedoch auch die Anordnung flacher Metallstreifen, die aufgrund einer geringen Dicke eine entsprechend geringe Biegesteifigkeit besitzen, jedoch erhebliche Zugfestigkeit haben.It goes without saying that instead of the
