PUM-114 PCT 29. März 2010 PUM-114 PCT March 29, 2010
Schuh, insbesondere SportschuhShoe, in particular sports shoe
Die Erfindung betrifft einen Schuh, insbesondere einen Sportschuh, mit einer Sohle, wobei die Sohle mit mindestens einem Federelement versehen ist, das die Biegesteifigkeit der Sohle um eine Achse, die horizontal und senkrecht zu einer Längsrichtung der Sohle ausgerichtet ist, erhöht.The invention relates to a shoe, in particular a sports shoe, with a sole, wherein the sole is provided with at least one spring element, which increases the flexural rigidity of the sole about an axis which is aligned horizontally and perpendicular to a longitudinal direction of the sole.
Ein Schuh dieser Art ist beispielsweise aus der WO 2008/000398 Al bekannt. Hier wird ein Schuh mit einer steifen Einlegesohle versehen, die Federeigen- Schäften aufweist, um die Biegesteifigkeit des Schuhs um eine horizontale Querachse zu erhöhen und dem Schuh somit die Steifigkeit zu verleihen, die für seinen Gebrauch, beispielsweise als Laufschuh, nötig ist. Nachteilig kann bei einer solchen Lösung sein, dass der Handlingsaufwand relativ hoch ist, wenn es sich um einen üblichen Schuh handelt, nicht wie in der genannten Schrift um einen in Schuhlängsrichtung stauchbaren Schuh. Die eigensteife Einlegesohle muss nämlich bei Bedarf in den Schuh eingesetzt werden.A shoe of this kind is known, for example, from WO 2008/000398 A1. Here, a shoe is provided with a stiff insole having springy shanks to increase the flexural rigidity of the shoe about a horizontal transverse axis and thus provide the shoe with the rigidity needed for its use, for example as a running shoe. A disadvantage may be in such a solution that the handling effort is relatively high, if it is a conventional shoe, not as in the cited document to a compressible in the shoe longitudinal direction shoe. The inherently rigid insole must namely be used if necessary in the shoe.
Es ist auch bekannt, ein sich in Schuhlängsrichtung erstreckendes Verstärkungs- oder Federelement fest mit der Sohle zu verbinden, z. B. zu verkleben, um die Biegesteifigkeit um die Querachse zu erhöhen. Nachteilig ist hier, dass es zwischen dem Versteifungs- oder Federelement und der Schuhsohle bei der Einleitung von Biegemomenten um die Querachse und damit einher gehenden Biegeverformungen um diese Achse zu erheblichen Spannungen in der Schuhsohle kommen kann. Dabei besteht sogar die Gefahr des Brechens des Versteifungs- oder Federelements.It is also known to connect a shoe longitudinal direction extending reinforcing or spring element fixed to the sole, z. B. to increase the flexural rigidity around the transverse axis. The disadvantage here is that between the stiffening or spring element and the shoe sole in the introduction of bending moments about the transverse axis and associated bending deformations about this axis to considerable Tension in the shoe sole can come. There is even the risk of breaking the stiffening or spring element.
Der Erfindung liegt daher die A u f g a b e zugrunde, einen Schuh, insbesondere einen Sportschuh, der eingangs genannten Art so fortzubilden, dass die genannte Problematik verhindert wird. Es soll also ein Schuh geschaffen werden, dessen Sohle ohne separate Maßnahmen, d. h. ohne ein Federelement einsetzen zu müssen, eine hinreichende Biegesteifigkeit bzw. Federeigenschaft um eine horizontale Achse, die quer zur Längsachse steht, durch ein inkorporiertes Federelement aufweist, wobei dieses allerdings so angeordnet ist, dass auch bei großen Biegeverformungen keine Gefahr des Brechens des Federelements besteht. Damit soll erreicht werden, dass insbesondere bei der Anwendung in einem Fußballschuh eine Schusskrafterhöhung möglich wird und somit die Schussgeschwindigkeit positiv beeinflusst werden kann. Bei normalen Laufen soll indes keine unerwünscht hohe Steifigkeit vorliegen.The invention is therefore based on the invention, a shoe, in particular a sports shoe, of the type mentioned in such a way that the above problem is prevented. So it should be created a shoe whose sole without separate measures, d. H. Without having to use a spring element, a sufficient bending stiffness or spring property about a horizontal axis, which is transverse to the longitudinal axis, by an incorporated spring element, but this is arranged so that there is no risk of breakage of the spring element even with large bending deformations. This is intended to ensure that, in particular when used in a football boot, a firing force increase becomes possible and thus the firing speed can be positively influenced. In normal running, however, should not be undesirable high stiffness.
Die L ö s u n g dieser Aufgabe durch die Erfindung ist dadurch gekennzeichnet, dass die Sohle mindestens eine Aumahmenut für das mindestens eine Federelement aufweist, in der das Federelement so angeordnet ist, dass es zumindest über einen Teil seiner Erstreckung in Längsrichtung relativ zu der Sohle gleiten kann.The solution to this problem by the invention is characterized in that the sole has at least one frame groove for the at least one spring element in which the spring element is arranged so that it can slide over at least part of its extension in the longitudinal direction relative to the sole ,
Das Federelement ist dabei bevorzugt zumindest über eine wesentliche Längserstreckung, insbesondere über mindestens 75 % seiner Länge gemessen in Längsrichtung, streifenförmig ausgebildet.The spring element is preferably formed strip-shaped at least over a substantial longitudinal extent, in particular over at least 75% of its length measured in the longitudinal direction.
Das Federelement kann in einem Schnitt senkrecht zur Längsrichtung zumindest abschnittsweise eine rechteckige Form aufweisen. Damit der Träger des Schuhs keine Beeinträchtigung durch die vorgeschlagene Ausgestaltung erleidet, bilden die Oberseite des Federelements und die Oberseite der Sohle vorzugsweise eine weitgehend bündige Fläche.The spring element may have a rectangular shape at least in sections in a section perpendicular to the longitudinal direction. In order for the wearer of the shoe not to be adversely affected by the proposed embodiment, the upper side of the spring element and the upper side of the sole preferably form a largely flush surface.
Das Federelement kann an einem axialen Ende eine Verbreiterung in horizontale Richtung quer zur Längsrichtung aufweisen, um die Festlegung an der Sohle zu erleichtern. Die Verbreiterung ist dabei bevorzugt im vorderen Endbereich des Federelements angeordnet. Das Federelement samt seiner Verbreiterung kann dabei in der Draufsicht die Form eines T aufweisen.The spring element may have a broadening in horizontal direction transversely to the longitudinal direction at one axial end in order to facilitate the fixing to the sole. The broadening is preferably arranged in the front end region of the spring element. The spring element together with its broadening can have the shape of a T in plan view.
Das Federelement ist gemäß einer bevorzugten Ausführungsform der Erfindung mit mindestens einer Schraubverbindung mit der Sohle verbunden. Weiter sieht eine besonders bevorzugte Ausführungsform der Erfindung vor, dass die Schraubverbindung gleichzeitig einen Stollen an der Unterseite der Sohle festlegt.The spring element is connected according to a preferred embodiment of the invention with at least one screw with the sole. Furthermore, a particularly preferred embodiment of the invention provides that the screw connection simultaneously defines a lug on the underside of the sole.
Das Federelement besteht bevorzugt aus Kunststoff, in das Verstärkungs- fasern eingelagert sind. Bei den Verstärkungsfasern handelt es sich zumeist um Glasfasern oder Kohlenstofffasern.The spring element is preferably made of plastic, are embedded in the reinforcing fibers. The reinforcing fibers are mostly glass fibers or carbon fibers.
Der bevorzugte Anwendungsfall der Erfindung ist derjenige des Fußballschuhs.The preferred application of the invention is that of the soccer shoe.
Bei diesem macht sich der Vorteil des vorgeschlagenen Schuhs besonders gut bemerkbar, dass nämlich bei der Verformung der Schuhsohle (durch Biegung um eine zur Längsachse horizontale Querachse) Energie im Federelement gespeichert werden kann, die dann beim Schuss des Balls abgegeben wird (ähnlich wie bei einem Katapult). Damit kann die Schusskraft erhöht und somit die Schussgeschwindigkeit positiv beeinflusst werden.In this, the advantage of the proposed shoe is particularly noticeable, namely that in the deformation of the shoe sole (by bending about a horizontal axis to the longitudinal axis transverse axis) energy can be stored in the spring element, which is then released when shooting the ball (similar to a catapult). Thus, the firing force can be increased and thus the firing speed can be positively influenced.
Allerdings bewirkt das Federelement dennoch in vorteilhafter Weise aufgrund der vorgeschlagenen Ausgestaltung keine zusätzliche Versteifung wie bei vorbekannten Lösungen.However, the spring element nevertheless advantageously causes no additional stiffening as in previously known solutions due to the proposed embodiment.
Dadurch, dass das Federelement in seiner Aufnahmenut in der Sohle über die wesentliche Erstreckung in Längsrichtung relativ zur Sohle gleiten kann, können sich also bei Biegung der Sohle um eine horizontale Querachse keine Spannungen im Federelement aufbauen, die kritisch hinsichtlich eines Brechens des Federelements werden können.Due to the fact that the spring element in its receiving groove in the sole can slide over the substantial extent in the longitudinal direction relative to the sole, can thus build upon bending the sole about a horizontal transverse axis no stresses in the spring element, which can be critical with respect to a breaking of the spring element.
Vielmehr kommt es durch eine Gleitbewegung des Federelements relativ zum Nutgrund in der Sohle zu Ausgleichsbewegungen, so dass das Federelement stets das gleiche Widerstandsmoment gegen Biegemomente um die Querachse aufbringt. Das Widerstandsmoment der Sohle samt Federelement ist daher weitgehend konstant, was eine einfachere Auslegung des Schuhs hinsichtlich seines Biegeverhaltens um die Querachse möglich macht.Rather, by a sliding movement of the spring element relative to the groove bottom in the sole to compensatory movements, so that the spring element always applies the same moment of resistance against bending moments about the transverse axis. The moment of resistance of the sole including spring element is therefore largely constant, which makes a simpler interpretation of the shoe in terms of its bending behavior about the transverse axis possible.
In der Zeichnung ist ein Ausfuhrungsbeispiel der Erfindung dargestellt. Es zeigen:In the drawing, an embodiment of the invention is shown. Show it:
Fig. 1 in perspektivischer Ansicht die Sohle eines Sportschuhs,1 is a perspective view of the sole of a sports shoe,
Fig. 2 einen Schnitt senkrecht zur Längsrichtung der Sohle (Schnitt A-B in Fig. 1) und Fig. 3 einen Schnitt durch einen Ausschnitt der Sohle entlang der Längsrichtung (Schnitt C-D gemäß Fig. 1).Fig. 2 is a section perpendicular to the longitudinal direction of the sole (section AB in Fig. 1) and Fig. 3 is a section through a section of the sole along the longitudinal direction (section CD of FIG. 1).
In den Figuren ist eine Sohle 1 eines Sportschuhs zu sehen, die in bekannter Weise mit einem nicht dargestellten Schuhoberteil verbunden wird. Die Sohle weist eine dem Fuß des Trägers angepasste Form auf, d. h. sie ist schalenförmig ausgebildet. Die Sohle 1 aus den üblichen Materialien ist mit einem Federelement 2 versehen, um der Sohle 1 ein erhöhtes Biegewiderstandsmoment zu verleihen, wenn sie eine Beaufschlagung mit einem Biegemoment erfahrt, das horizontal und quer zu der Längsrichtung L des Schuhs bzw. der Sohle 1, d. h. um die Achse Q wirkt. Die Beaufschlagung der Schuhsohle 1 mit einem solchen Biegemoment ist typisch, wenn der Schuh auf dem Boden auftrifft und bei einem Schritt auf dem Boden abrollt.In the figures, a sole 1 of a sports shoe to see, which is connected in a known manner with a shoe upper, not shown. The sole has a shape adapted to the foot of the wearer, i. H. it is cup-shaped. The sole 1 of the usual materials is provided with a spring element 2 to give the sole 1 an increased bending resistance moment when it experiences an application with a bending moment horizontally and transversely to the longitudinal direction L of the shoe or the sole 1, d , H. around the axis Q acts. The application of the shoe sole 1 with such a bending moment is typical when the shoe hits the ground and rolls on the ground in one step.
Das Federelement 2 ist dabei nicht über seine gesamte Erstreckung fest mit der Sohle 1 verbunden, sondern ist in einer Aufhahmenut 3 in der Sohle 1 angeordnet. Wie Fig. 2 entnommen werden kann, ist die Aufhahmenut 3 - genauso wie das Federelement 2 - in einem Schnitt senkrecht zur Längsrichtung L im Wesentlichen rechteckformig ausgebildet. Dabei ist das Federelement 2 geringfügig schmaler als die Breite der Aufhahmenut 3, wie es in Fig. 2 gesehen werden kann.The spring element 2 is not connected over its entire extent fixed to the sole 1, but is arranged in a Aufhahmenut 3 in the sole 1. Die Aufsprüche 3 sind in der Ausnehmung 3 in der Sole 1 angeordnet. As can be seen in FIG. 2, the Aufhahmeut 3 - as well as the spring element 2 - in a section perpendicular to the longitudinal direction L is formed substantially rechteckformig. In this case, the spring element 2 is slightly narrower than the width of the Aufhahmeut 3, as can be seen in Fig. 2.
Das Federelement 2 ist im Zehenbereich der Sohle 1 fest mit der Sohle 1 verbunden, ansonsten liegt es frei in der Aufnahmenut 3, geführt von den Seitenflächen 9 der Aufnahmenut 3. Kommt es zu einer Biegung um die Achse Q, z. B. beim Abrollen des Schuhs auf dem Boden, verformen sich die Sohle 1 und das Federelement 2 infolge der geometrischen Verhältnisse nicht gleichförmig, sondern leicht unterschiedlich. Dieser Unterschiedsbetrag wird dadurch ausgeglichen, dass das Federelement 2 in der Aufhahmenut 3 in Längsrichtung L gleitet. Hierfür weist die Aufnahmenut 3 in ihrem hinteren Endbereich eine geringfügig weitere Ausdehnung aus, als es dem Federelement 2 entsprechen würde, s. Freiraum 10.The spring element 2 is firmly connected to the sole 1 in the toe region of the sole 1, otherwise it is exposed in the receiving groove 3, guided by the side surfaces 9 of the receiving groove 3. If there is a bend about the axis Q, z. B. when rolling the shoe on the ground, deform the sole 1 and the spring element 2 due to the geometric conditions not uniform, but slightly different. This difference will be thereby compensated that the spring element 2 slides in the Aufhahmenut 3 in the longitudinal direction L. For this purpose, the receiving groove 3 in its rear end region a slightly wider extent than would correspond to the spring element 2, s. Free space 10.
Das Federelement 2 ist vorzugsweise (in Abhängigkeit der Schuhgröße) zwischen 15 cm und 28 cm lang und hat einen im Querschnitt rechteckförmigen, streifenförmigen Abschnitt, der eine Länge zwischen 10 cm und 23 cm aufweisen kann. Dieser im Querschnitt rechteckförmige Abschnitt ist bevorzugt zwischen 10 mm und 20 mm breit und hat vorzugsweise eine Höhe zwischen 1 mm und 4 mm.The spring element 2 is preferably (depending on the shoe size) between 15 cm and 28 cm long and has a rectangular cross-section, strip-shaped portion, which may have a length between 10 cm and 23 cm. This section, which is rectangular in cross-section, is preferably between 10 mm and 20 mm wide and preferably has a height of between 1 mm and 4 mm.
Wie weiter gesehen werden kann, sind die Oberseite 4 des Federelements 2 und die Oberseite 5 der Sohle 1 bündig, so dass der Träger des Schuhs durch das sich in der Aufnahmenut 3 befindliche Federelement 2 nicht behindert wird.As can further be seen, the upper side 4 of the spring element 2 and the upper side 5 of the sole 1 are flush, so that the wearer of the shoe is not hindered by the spring element 2 located in the receiving groove 3.
Die Befestigung des Federelements 2 erfolgt - wie erwähnt - im Zehenbereich der Sohle 1. Hierfür weist das Federelement 2 in diesem Bereich eine Verbreiterung 6 auf, so dass das Federelement 2 insgesamt in der Draufsicht die Form eines T aufweist. Im Bereich der Verbreiterung 6 sind vorliegend zwei Bohrungen im Federelement 2 angebracht, in die von oben eine Schraubhülse 11 gesteckt werden kann (s. Fig. 3). Die Schraubhülse 11 hat in oberen Bereich eine scheibenförmige Verbreiterung 12, die mit (nicht dargestellten) Dornen versehen sein kann, die sich in das Federelement 2 drücken und so einen festen Verbund mit diesem schaffen. Nach unten schließt sich an die scheibenförmige Verbreiterung 12 ein Schraubschaft 13 an, der mit einem Gewinde versehen ist. Die Sohle 1 ist an dieser Stelle mit einer Bohrung versehen, so dass sich der Schraubschaft 13 nach unten bis zur Sohlenunterseite erstrecken kann. Von unten wird ein Stollen 8 eingeschraubt, d. h. der Stollen 8 ist mit einem Gewindeabschnitt 14 versehen, mit dem er in den Schraubschaft 13 eingeschraubt werden kann.The attachment of the spring element 2 takes place - as mentioned - in the toe area of the sole 1. For this purpose, the spring element 2 in this area on a broadening 6, so that the spring element 2 has a total of the shape of a T in the plan view. In the area of widening 6, two bores are present in the spring element 2, into which a threaded sleeve 11 can be inserted from above (see FIG. 3). The screw sleeve 11 has a disk-shaped widening 12 in the upper area, which can be provided with (not shown) thorns, which press into the spring element 2 and thus create a firm bond with this. Down to the disk-shaped widening 12 is followed by a screw shaft 13, which is provided with a thread. The sole 1 is provided at this point with a bore, so that the screw shaft 13 down to the Sole bottom can extend. From below, a stud 8 is screwed in, ie the stud 8 is provided with a threaded portion 14, with which it can be screwed into the screw shaft 13.
In vorteilhafter Weise wird hiermit nicht nur der Schraub-Stollen 8 an der Sohlenunterseite fixiert, gleichzeitig wird in einfacher Weise und mit wenig Bauteilen das Federelement 2 an der Sohle 1 festgelegt, und zwar ausschließlich im Zehenbereich der Sohle, so dass die erwähnte Ausgleichsfunktion nicht beeinträchtigt ist.Advantageously, hereby not only the screw lug 8 is fixed to the underside of the sole, at the same time the spring element 2 is fixed to the sole 1 in a simple manner and with few components, specifically only in the toe area of the sole, so that the mentioned compensation function is not impaired is.
Im Falle dessen, dass keine Stollen vorgesehen sind, kann die Befestigung des Federelements 2 mit der Sohle 1 durch separate Schrauben erfolgen, die ausschließlich die Funktion haben, das Federelement 2 an der Sohle 1 zu fixieren. In the case that no studs are provided, the attachment of the spring element 2 with the sole 1 can be effected by separate screws, which have only the function to fix the spring element 2 to the sole 1.
