Description

Die vorliegende Erfindung betrifft eine Laufsohle für einen Sportschuh, insbesondere Skilanglauf- oder Telemark-Schuh, gemäß dem Oberbegriff des Anspruches 1.The present invention relates to an outsole for a sports shoe, in particular cross-country skiing or telemark shoe, according to the preamble of claim 1.

In der Praxis sind Laufsohlen für Skilanglauf- oder Telemark-Schuhe bekannt, die schaftseitig mit Längs- und Querrippen versehen sind. Diese Längs- und Querrippen begrenzen entsprechende Ausnehmungen, so daß mit minimalem Materialaufwand eine maximale Stabilität, insbesondere Torsionsstabilität erhalten wird. Die Anmelderin hat derartige Laufsohlen unter der Marke "NNN" seit Jahren hergestellt und vertrieben. Diese Laufsohlen sind des weiteren dadurch gekennzeichnet, daß sie laufseitig jeweils zwei Längsführungsnuten sowie sich daran anschließende Quernuten aufweisen, wobei die Längsführungsnuten sich über die gesamte Sohlenlänge erstrecken und mit komplementären Längsführungsrippen auf einer zugeordneten Skibindungsplatte zusammenwirken. Am vorderen Sohlenende ist laufseitig eine Querachse innerhalb einer laufseitig vorgesehenen Ausnehmung zum gelenkigen Anschluß an eine Skibindung vorgesehen, wobei die Anlenkung derart ist, daß der Schuhabsatz frei angehoben werden kann. Die Längsführungsnuten sind nicht nur innerhalb des Laufbelages, sondern auch innerhalb der Laufsohle selbst ausgebildet. Dadurch wird die Biegeelastizität, insbesondere im metatarsophalangischen Bereich der Laufsohle erheblich beeinträchtigt. Um dieses Problem zu lösen, ist in der EP 0 787 440 B1 vorgeschlagen, die Laufsohle eines Sportschuhs aus zwei Teilen herzustellen, wobei das hintere steif ausgebildet und das vordere Teil aus einem weichen Material hergestellt ist. Diese Ausführungsform hat jedoch den Nachteil, daß die Sohle nicht durchgehend aus ein und demselben Material hergestellt werden kann, zum Beispiel durch Spritzgießen. Der Aufwand für die Sohlenherstellung ist also unverhältnismäßig groß, wobei in der EP 0 787 440 B1 diesbezüglich noch vorgeschlagen wird, das vordere und hintere Teil jeweils mit Überlappung aneinander zu fügen.In practice, outsoles for cross-country skiing or telemark shoes are known, which are provided on the shaft side with longitudinal and transverse ribs. These longitudinal and transverse ribs define corresponding recesses so that maximum stability, in particular torsional stability, is obtained with minimal material expenditure. The applicant has been producing and selling such outsoles under the trademark "NNN" for years. These outsoles are further characterized in that they each have on the running side two Längsführungsnuten and adjoining transverse grooves, wherein the Längsführungsnuten extend over the entire sole length and cooperate with complementary longitudinal guide ribs on an associated ski binding plate. At the front end of the sole a transverse axis within a running side provided recess for articulated connection to a ski binding is provided on the running side, wherein the articulation is such that the heel can be lifted freely. The Längsführungsnuten are not only formed within the tread, but also within the outsole itself. As a result, the flexural elasticity is significantly impaired, especially in the metatarsophalangeal region of the outsole. To solve this problem is in the EP 0 787 440 B1 proposed to make the outsole of a sports shoe of two parts, wherein the rear is rigid and the front part is made of a soft material. However, this embodiment has the disadvantage that the sole can not be made continuously from one and the same material, for example by injection molding. The effort for sole production is therefore disproportionately large, in the EP 0 787 440 B1 In this regard, it is proposed to add the front and rear parts with overlapping each other.

Aus der DE 31 13 942 A1 ist ebenfalls eine Laufsohle für einen Langlauf-Skischuh der hier fraglichen Art bekannt, wobei diese bekannte Laufsohle die Merkmale des Oberbegriffs des Anspruches 1 umfaßt.From the DE 31 13 942 A1 is also an outsole for a cross-country ski boot of the type in question here known, said known outsole comprising the features of the preamble of claim 1.

Ähnlich verhält es sich bei der Laufsohle gemäß der US-A-4,186,500 .Similarly, the outsole according to the US-A-4,186,500 ,

Ausgehend von dem vorgenannten Stand der Technik liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine Laufsohle der im Oberbegriff des Anspruches 1 genannten Art so weiterzuentwickeln, daß sowohl die Biegeelastizität als auch die Torsionsstabilität ohne zusätzlichen Fertigungsaufwand noch präziser eingestellt werden kann.Based on the aforementioned prior art, the present invention seeks to develop an outsole referred to in the preamble of claim 1 species so that both the flexural elasticity and the torsional stability can be set even more precise without additional manufacturing effort.

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

Ein wesentlicher Aspekt der vorliegenden Erfindung liegt also darin, daß zumindest der vordere Abschnitt der aus relativ hartem Material bestehenden Laufsohle keine Nuten oder Rippen aufweist, die der Flexibilität zumindest im Bereich der sogenannten metatarsophalangischen Zone entgegenwirken. Der vordere Abschnitt der harten Grund- bzw. Laufsohle ist als dünnwandige und sowohl innen- als auch außenseitig im wesentlichen glatte Schale ausgebildet.An essential aspect of the present invention is therefore that at least the front portion of the existing of relatively hard material outsole has no grooves or ribs, which counteract the flexibility at least in the region of the so-called metatarsophalangeal zone. The front portion of the hard base or outsole is formed as a thin-walled and both inside and outside substantially smooth shell.

Vorzugsweise besteht die Laufsohle aus einem Kunststoff mit einem Elastizitätsmodul von zwischen 200 MPa und 250 GPa, insbesondere zwischen 350 MPa und 200 GPa, wobei der Elastizitätsmodul die Dicke im vorderen Abschnitt bestimmt dergestalt, dass bei höherer Elastizität die Dicke prozentual größer ist als bei geringerer Elastizität. Das heißt, je steifer das Sohlenmaterial ausgebildet, desto dünner muß zumindest im metatarsophalangischen Bereich die Grundsohle bei entsprechend dickerer Ausbildung des weicheren Laufbelages gestaltet sein.The outsole is preferably made of a plastic having a modulus of elasticity of between 200 MPa and 250 GPa, in particular between 350 MPa and 200 GPa, wherein the modulus of elasticity determines the thickness in the front section such that the thickness is higher in percentage with greater elasticity than with less elasticity , That is, the stiffer the sole material is formed, the thinner must be designed at least in the metatarsophalangeal region, the bottom sole with a correspondingly thicker design of the softer tread.

Wie erwähnt, soll die erfindungsgemäße Laufsohle laufseitig mit wenigstens einer Längsführungsnut und zumindest im Bereich der metatarsophalangischen Zone mit einer oder mehreren Quernuten ausgebildet sein, wobei diese Nuten zumindest im vorderen Abschnitt der Laufsohle im wesentlichen nur innerhalb des Laufbelages aus weicherem Material ausgebildet sind. Der vordere Sohlenabschnitt, der aus härterem Material hergestellt ist, stellt also eine dünnwandige und sowohl innen- als auch außenseitig im wesentlichen glatte Schale dar. Durch die vorgenannte Schalenkonfiguration wird die erforderliche Steifigkeit, insbesondere Torsionssteifigkeit der Laufsohle gewährleistet.As mentioned, the outsole according to the invention should be designed with at least one Längsführungsnut and at least in the metatarsophalangeal zone with one or more transverse grooves, these grooves are formed at least in the front portion of the outsole substantially only within the tread of softer material. The front sole portion, which is made of a harder material, so represents a thin-walled and both inside and outside substantially smooth shell. By the aforementioned shell configuration, the required rigidity, in particular torsional stiffness of the outsole is guaranteed.

Die Konfiguration gemäß Anspruch 5, wonach die Quernuten zumindest im vorderen Abschnitt jeweils nach hinten bogenförmig ausgebildet sind, erhöht bei unveränderter Flexibilität die Stabilität der Sohle, insbesondere Torsionsstabilität.The configuration according to claim 5, according to which the transverse grooves are arched in each case at least in the front section, increases the stability of the sole, in particular torsional stability, with unchanged flexibility.

Erwähnenswert ist noch die Detailkonstruktion gemäß Anspruch 8, wonach in die seitliche Begrenzung der Ausnehmung am vorderen Sohlenende zur Aufnahme einer Querachse mit dieser verbundene Verankerungselemente, insbesondere aus Metall, integriert sind. Diese Verankerungselemente sind insbesondere dann erforderlich, wenn die Querachse im relativ weichen Laufbelag verankert werden soll. Es ist natürlich auch denkbar, in herkömmlicher Weise die Ausnehmung am vorderen Sohlenende zur Aufnahme der Querachse durch zwei Seitenwangen aus hartem Sohlenmaterial zu begrenzen, die integral mit der Laufsohle verbunden sind.Also worth mentioning is the detailed construction according to claim 8, according to which are integrated in the lateral boundary of the recess at the front sole end for receiving a transverse axis with this anchoring elements, in particular made of metal. These anchoring elements are required in particular when the transverse axis is to be anchored in the relatively soft tread. Of course, it is also conceivable, in a conventional manner, the recess at the front sole end for receiving the transverse axis by two To limit side cheeks made of hard sole material, which are integrally connected to the outsole.

Der Laufbelag wird laufseitig auf die Laufsohle entweder aufgeschweißt oder aufgeklebt.The tread is either welded or glued to the outsole on the running side.

Schließlich sei noch erwähnt, dass bei unverändert vorbestimmter Gesamtdicke die Dicke des vorderen Abschnitts der Laufsohle, die aus härterem Material hergestellt ist, ausgehend von der metatarsophalangischen Biegezone zumindest in Richtung nach hinten stetig zunehmend auszubilden. Der hintere Abschnitt, insbesondere der Absatz der Laufsohle ist vorzugsweise herkömmlich ausgebildet, d.h. schaftseitig mit material- und gewichtsreduzierenden Ausnehmungen versehen.Finally, it should be mentioned that with unchanged predetermined total thickness, the thickness of the front portion of the outsole, which is made of a harder material, starting from the metatarsophalangeal bending zone at least in the direction towards the rear steadily increasingly form. The rear portion, in particular the heel of the outsole, is preferably formed conventionally, i. provided on the shank side with material and weight-reducing recesses.

Nachstehend wird eine bevorzugte Ausführungsform einer erfindungsgemäßen Laufsohle anhand der beigefügten Zeichnung näher erläutert. Diese zeigt in:

Hereinafter, a preferred embodiment of an outsole according to the invention will be explained in more detail with reference to the accompanying drawings. This shows in:
Fig. 1
an outsole according to the invention in a perspective view from below;
Fig. 2
the outsole according to Fig. 1 in plan view and enlarged scale; and
Fig. 3
a longitudinal section through the outsole according to the Fig. 1 and 2 Longitudinal line III-III in Fig. 2 , on a smaller scale.

In den Fig. 1 und 2 ist eine Laufsohle 10 für einen Langlauf-Skischuh jeweils von der Unterseite dargestellt. Diese Laufsohle besteht aus einem hinteren, einen Schuhabsatz 13 umfassenden Abschnitt 11 und einem vorderen, leicht schalenförmig, d.h. flachschalenförmig konfigurierten Abschnitt 12, wobei die Laufsohle 10 durchgehend aus einem relativ harten Material, insbesondere Kunststoff hergestellt und laufseitig sowohl im Bereich des vorderen als auch im Bereich des hinteren Abschnitts mit einem Laufbelag 14 aus relativ weichem, insbesondere gummiartigem Material versehen ist. Dieser Laufbelag 14 definiert zusammen mit den zugeordneten Laufsohlenabschnitten 11 und 12 eine vorbestimmte Gesamtsohlendicke bzw. Sohlenhöhe "h", wie sie in Fig. 3 im Bereich einer sog. metatarsophalangischen Biegezone "M" dargestellt ist. Der vordere Abschnitt 12 der Laufsohle 10 ist zumindest schaftseitig - beim dargestellten Ausführungsbeispiel auch laufseitig - im wesentlichen durchgehend glatt ausgebildet. Des weiteren weist der vordere Abschnitt 12 der Laufsohle 10 bei unverändert vorbestimmter Gesamtdicke "h" aus hartem und weichem Material zumindest im Bereich der metatarsophalangischen Zone "M" eine erheblich reduzierte Dicke "d" auf, die maximal etwa 50 %, insbesondere - wie auch hier dargestellt - 25-30 % der Gesamtdicke "h" aus hartem und weichem Material entspricht.In the Fig. 1 and 2 is an outsole 10 for a cross-country ski boot each shown from the bottom. This outsole consists of a rear, a shoe heel 13 comprehensive section 11 and a front, slightly cup-shaped, ie flat shell-shaped configured section 12, wherein the outsole 10 continuously made of a relatively hard material, in particular plastic and running side both in the front and in the Region of the rear portion is provided with a tread 14 of relatively soft, especially rubber-like material. This tread 14 defines together with the associated outsole portions 11 and 12 a predetermined total sole thickness or sole height "h", as in Fig. 3 in the area of a so-called metatarsophalangic Bending zone "M" is shown. The front portion 12 of the outsole 10 is formed at least on the shaft side - in the illustrated embodiment, the running side - substantially continuous smooth. Furthermore, the front portion 12 of the outsole 10 at unchanged predetermined total thickness "h" of hard and soft material at least in the metatarsophalangeal zone "M" a significantly reduced thickness "d", the maximum about 50%, in particular - as well shown here - 25-30% of the total thickness "h" of hard and soft material corresponds.

Die Laufsohle besteht aus einem Kunststoff mit einem Elastizitätsmodul wie oben angegeben. Sie lässt sich in einfacher Weise durch Spritzgießen herstellen. Der Laufbelag aus weichem Material wird laufseitig auf das härtere Material aufgeschweißt oder aufgeklebt.The outsole is made of a plastic with a modulus of elasticity as stated above. It can be produced in a simple manner by injection molding. The tread of soft material is welded on the side of the harder material or glued on.

Laufseitig weist die Laufsohle zwei Längsführungsnuten 15 und mehrere Quernuten 16 auf, wobei diese Nuten im wesentlichen nur innerhalb des Laufbelages 14 aus weicherem Material ausgebildet sind. Der Grund zumindest der Längsnuten 15 im Bereich des vorderen Sohlenabschnitts ist durch das relativ harte Material der Laufsohle definiert. Vorzugsweise sind die Längs- und Quernuten so ausgebildet, dass ihre Tiefe in etwa gleich groß bemessen ist.Running side, the outsole has two Längsführungsnuten 15 and a plurality of transverse grooves 16, said grooves are formed substantially only within the tread 14 of softer material. The reason for at least the longitudinal grooves 15 in the region of the front sole portion is defined by the relatively hard material of the outsole. Preferably, the longitudinal and transverse grooves are formed so that their depth is dimensioned approximately equal.

Wie die Fig. 1 und 2 sehr gut erkennen lassen, sind die Quernuten 16 sowohl im vorderen Abschnitt 12 als auch im hinteren Abschnitt 11 jeweils nach hinten bogenförmig ausgebildet.As the Fig. 1 and 2 can be seen very well, the transverse grooves 16 are formed both in the front portion 12 and in the rear portion 11 each arcuate to the rear.

Am vorderen Ende der Laufsohle ist eine zur Laufseite hin offene Ausnehmung 17 ausgebildet, innerhalb der eine Querachse 18 zum gelenkigen Anschluß an eine nicht dargestellte Skibindung angeordnet ist. Die Ausnehmung 17 ist seitlich durch zwei Stege 19 aus hartem Sohlenmaterial begrenzt. Alternativ kann die Begrenzung auch durch den Laufbelag 14 erfolgen. In letztgenanntem Fall ist es zweckmäßig, in die seitliche Begrenzung der Ausnehmung 17 mit der Querachse 18 verbundene Verankerungselemente aus Metall zu integrieren.At the front end of the outsole to the running side open recess 17 is formed, within which a transverse axis 18 is arranged for articulated connection to a ski binding, not shown. The recess 17 is bounded laterally by two webs 19 of hard sole material. Alternatively, the limitation can also be done by the tread 14. In the latter case, it is expedient to integrate into the lateral boundary of the recess 17 with the transverse axis 18 connected anchoring elements made of metal.

Der Fig. 3 kann noch entnommen werden, dass bei unverändert vorbestimmter Gesamtdicke "h" die Dicke "d" des vorderen Abschnitts 12 der aus härterem Material bestehenden Sohle ausgehend von der metatarsophalangischen Zone "M" sowohl in Richtung nach hinten als auch in Richtung nach vorne stetig zunimmt. Damit wird eine metaphalangische Biegezone "M" durch die Dimensionierung von hartem und weichem Material definiert.Of the Fig. 3 can still be found that with unchanged predetermined total thickness "h", the thickness "d" of the front portion 12 of the harder material sole from the metatarsophalangeal zone "M" both in the backward direction also steadily increasing towards the front. Thus, a metaphalangic bending zone "M" is defined by the dimensioning of hard and soft material.

Der Schuhabsatz 13 kann in herkömmlicher Weise ausgebildet sein, insbesondere so wie in Fig. 3 dargestellt. Das heißt, der Absatz weist schaftseitig material- und gewichtsreduzierende Ausnehmungen 20 auf.The heel 13 may be formed in a conventional manner, in particular as in Fig. 3 shown. That is, the paragraph has on the shank side material and weight reducing recesses 20.

Es sei an dieser Stelle auch noch darauf hingewiesen, dass durch die glatte, flachschalenartige Ausbildung des vorderen Abschnitts der Laufsohle 10 es möglich ist, die Tiefe der Quernuten entsprechend der Tiefe der Längsführungsnuten zu dimensionieren. Die Quernuten können nicht mit Ausnehmungen an der Schaftseite der Laufsohle kollidieren.It should also be noted at this point that it is possible to dimension the depth of the transverse grooves according to the depth of the Längsführungsnuten by the smooth, flat-shell-like design of the front portion of the outsole 10. The transverse grooves can not collide with recesses on the shaft side of the outsole.
