Description

Die Erfindung betrifft einen austauschbaren Schuhabsatz, ein adaptierbares Schuhsohlenteil sowie einen Schuh, der einen solchen austauschbaren Schuhabsatz und ein solches adaptierbares Schuhsohlenteil umfasst. Ein solcher Schuh ist durch die Kombination unterschiedlich geformter Schuhabsätze (insbesondere mit unterschiedlicher Stöckelhöhe) und Schuhsohlenteile in Form und Höhe transformierbar.The invention relates to an exchangeable shoe heel, an adaptable shoe sole part and a shoe comprising such an exchangeable shoe heel and such an adaptable shoe sole part. Such a shoe is transformable by the combination of different shaped heels (especially with different heights) and shoe sole parts in shape and height.

Um Schuhe flexibel zu gestalten, ist es bekannt, einzelne Schuhteile auszutauschen oder zu verändern. So finden sich austauschbare Absätze ( DE000002923926A1 , DE000001719681U , DE000029811942U1 , DE2919639 , DE000001761534U , EP0314411 , ES2006324 , GR88100086 , GB2004176 , CN2720858Y , US000004610100A , US6023858 , US2003163934 , US6711835 , JP8066204 , JP59028903 , JP10215914 , JP2003319802 ), eine veränderbare Absatzhöhe ( DE29702665U , DE000029711890U1 , DE000020303615U1 , US000002707341A , US000006021586A , JP1110301 ), wechselbare Laufsohlen ( US2005055844 , JP2004129815 ) oder ein verstellbarer Gehgrad ( DE000020309485U1 , DE1909270U , DE202005007804U , US3464126 ). Das bekannte flexible Schuhwerk bewältigt das komplexe Zusammenwirken der verschiedenen Schuhteile im Rahmen eines adaptierbaren Gesamtschuhs aber nur sehr eingeschränkt, indem einzelne Schuhteile durch mechanische Vorrichtungen verbunden werden ( US000004416072A , JP53119147 ). In jeder der bekannten Ausführungsformen werden wichtige technische Aspekte ausgeklammert - wie die notwendige Anpassung von Gehgrad ( US2003136028 , US5309651 ), Fersenstellung ( JP53119147 ) oder Laufsohlenposition ( US000002258265A , US000004416072A ). Daraus resultieren die Vernachlässigung des weitreichenden Zusammenspiels diverser Schuhteile, die isolierte Betrachtung einzelner Bereiche und damit Nachteile in Tragekomfort und Stabilität in den unbeachteten Schuhregionen.To make shoes flexible, it is known to replace individual shoe parts or change. So there are interchangeable paragraphs ( DE000002923926A1 . DE000001719681U . DE000029811942U1 . DE2919639 . DE000001761534U . EP0314411 . ES2006324 . GR88100086 . GB2004176 . CN2720858Y .

US000002707341A . US000006021586A . JP1110301 ), changeable outsoles ( US2005055844 . JP2004129815 ) or an adjustable walkway ( DE000020309485U1 . DE1909270U . DE202005007804U . US3464126 ). The known flexible footwear copes with the complex interaction of the various shoe parts in the context of an adaptable overall shoe but only very limited by individual shoe parts are connected by mechanical devices ( US000004416072A . JP53119147 ). In each of the known embodiments, important technical aspects are excluded - such as the necessary adaptation of the degree of walking ( US2003136028 . US5309651 ), Heel position ( JP53119147 ) or outsole position ( US000002258265A . US000004416072A ). This results in the neglect of the far-reaching interaction of various shoe parts, the isolated consideration of individual areas and thus disadvantages in wearing comfort and stability in the unnoticed shoe regions.

Der Erfindung liegt die Aufgabe zugrunde, das komplexe Zusammenwirken der verschiedenen Schuhteile im Rahmen eines transformablen Gesamtschuhs ganzheitlich durch die Nutzung von Druck und die dadurch erzeugte Spannung zu bewältigen und die Komfortwünsche des Trägers individuell zu optimieren, ohne dabei die Stabilität des Schuhs zu vernachlässigen. Insbesondere liegt der Erfindung die Aufgabe zugrunde, einen transformablen Kombinationsschuh mit adaptierbaren Schuhsohlenteilen und schnell austauschbaren Absätzen in unterschiedlicher Höhe und Form bereitzustellen, wobei während des bzw. durch den Wechsel des Absatzes das Schuhsohlenteil bzw. der gesamte Schuh automatisch mittels Aufwendung und Übertragung von Druck individuell angepasst und in der angepassten Position mit der durch den Druck erzeugten Spannung fixiert wird, um so den Gesamtschuh zu stabilisieren, ohne dass dafür eigene Vorrichtungen (z.B. mechanischer Art) zur Justierung, Fixierung oder Stabilisierung (wie Schrauben, Zahnräder etc.) erforderlich sind.The invention has for its object to handle the complex interaction of the various shoe parts in the context of a transformable overall shoe holistically by the use of pressure and the tension generated thereby and to optimize the comfort wishes of the wearer individually, without neglecting the stability of the shoe. In particular, the invention has for its object to provide a transformable combination shoe with adaptable shoe sole parts and quickly exchangeable heels in different height and shape, wherein during or through the change of heel the shoe sole part or the entire shoe automatically by means of expenditure and transfer of pressure individually adjusted and fixed in the adjusted position with the voltage generated by the pressure, so as to stabilize the entire shoe, without the need for its own devices (eg mechanical type) for adjustment, fixation or stabilization (such as screws, gears, etc.) are required.

Die vorliegende Erfindung löst die gestellte Aufgabe durch Bereitstellen eines austauschbaren Schuhabsatzes und eines dazupassenden Schuhsohlenteils, wobei der Schuhabsatz ein Druckerzeugungselement aufweist, das zum Angriff an bzw. zum Eingriff in das Schuhsohlenteil unter Druckausübung in Zehenrichtung auf einen Abschnitt des Schuhsohlenteils ausgebildet ist, wobei durch die Druckausübung im Schuhsohlenteil ein mechanischer Spannungszustand aufbaubar ist, der formverändernd auf zumindest einen Abschnitt des Schuhsohlenteils wirkt. Das Schuhsohlenteil weist zumindest einen Abschnitt auf, der durch variable Druckausübung in Zehenrichtung in seiner Winkelstellung in Bezug auf andere Schuhsohlenteilabschnitte und/oder seine Krümmung veränderbar ist, wobei durch die Druckausübung im Schuhsohlenteil ein mechanischer Spannungszustand aufgebaut wird, der formverändernd auf zumindest einen Abschnitt des Schuhsohlenteils wirkt. Es ist zu betonen, dass der Begriff "Schuhsohlenteil", wie hierin verwendet, nicht auf eine Schuhsohle an sich beschränkt ist, sondern auch jegliches mit einer Schuhsohle verbundenes Obermaterial in offener oder geschlossener Form umfasst. Ein aus einem erfindungsgemäßen Schuhabsatz und einem erfindungsgemäßen Schuhsohlenteil kombinierter Schuh ist in seiner Form nicht eingeschränkt und kann als Sandale, offener oder geschlossener Halbschuh, knöchelhoher Schuh oder auch Stiefel ausgebildet sein.The present invention solves this problem by providing an exchangeable shoe heel and a mating shoe sole part, the shoe heel having a pressure generating element adapted to engage the shoe sole part under pressure in the toe direction on a portion of the shoe sole part Exerting pressure in the shoe sole part a mechanical state of tension is buildable, which acts shape-changing on at least a portion of the shoe sole part. The shoe sole portion has at least a portion which is variable by varying pressure in the toe direction in its angular position with respect to other shoe sole portions and / or its curvature, wherein the pressure exerted in the shoe sole part a mechanical stress state is constructed, the shape-changing on at least a portion of the shoe sole part acts. It should be emphasized that the term "shoe sole part" as used herein is not limited to a sole of a shoe per se but also includes any upper material connected to a shoe sole in open or closed form. A shoe combined from a shoe heel according to the invention and a shoe sole part according to the invention is not limited in its shape and can be designed as a sandal, open or closed shoe, ankle-high shoe or even boots.

Aus der WO 01/78543 ist eine Unteranordnung zur Bildung eines Schuhs bekannt, umfassend ein flexibles Element, das in eine Basis des Schuhs inkorporiert wird und aufgrund seiner Flexibilität eine Vielzahl von Konfigurationen einnehmen kann, sowie einen Stöckel, der ein Stützelement aufweist, das mit dem flexiblen Element mechanisch in Eingriff bringbar ist, um das flexible Element in eine fußstützende Konfiguration zu bringen und den Stöckel mit dem flexiblen Element zu verbinden. Das flexible Element ist dabei nichts anderes als eine nachgiebige Hülle ohne definierte äußere Eigenform, ähnlich einem Gymnastikschuh, die sich an die Kontur des Stöckels und des Stützelements anpasst. Weder der Stöckel noch das Stützelement stellen ein "Druckerzeugungselement" im Sinne der vorliegenden Erfindung dar.From the WO 01/78543 For example, a subassembly for forming a shoe is known, comprising a flexible element that is incorporated into a base of the shoe and that can assume a variety of configurations due to its flexibility, and a toe having a support element that mechanically engages the flexible element engageable to bring the flexible element into a foot-supporting configuration and connect the stool to the flexible element. The flexible element is nothing more than a flexible shell without a defined outer shape, similar to a gymnastic shoe that adapts to the contour of the stool and the support element. Neither the stilts nor the support element constitute a "pressure generating element" in the sense of the present invention.

Durch seinen Wechsel spielt der Absatz mit seinen integrierten Komponenten eine aktive Rolle in Formgebung und Stabilisierung des transformablen Kombinationsschuhs. Auswechselbare Absätze sind zwar aus dem Stand der Technik bekannt, nicht jedoch, dass während des bzw. durch den Wechsel des Absatzes eine Formveränderung des Schuhsohlenteils bzw. des gesamten Schuhs stattfindet. Durch seine Ausgestaltung, insbesondere seine Länge und Neigung bestimmt das Druckerzeugungselement des austauschbaren Schuhabsatzes durch das Ausmaß der Druckerzeugung auf das Schuhsohlenteil den Gehgrad und das Ausmaß, in dem der Ballenteil der Laufsohle angehoben wird. Durch den Tausch von Absätzen mit unterschiedlicher Kombination von Form, Höhe, Fersenstellung sowie unterschiedlich ausgestalteten Druckerzeugungselementen kann in kurzer Zeit individuell auf die Komfortwünsche der Trägerin bzw. des Trägers reagiert werden.Through its change, the heel with its integrated components plays an active role in shaping and stabilizing the transformable combination shoe. Interchangeable paragraphs are known from the prior art, but not that during or by the change of paragraph a change in shape of Shoe sole part or the entire shoe takes place. By virtue of its configuration, in particular its length and inclination, the pressure generating element of the replaceable shoe heel determines the degree of walking and the extent to which the bale part of the outsole is raised by the extent of pressure generation on the sole part of the shoe. By exchanging heels with different combination of shape, height, heel position and differently designed pressure generating elements can be responded to in a short time individually to the comfort wishes of the wearer or the wearer.

In einer bevorzugten Ausgestaltung des erfindungsgemäßen austauschbaren Schuhabsatzes ist das Druckerzeugungselement als Vorsprung ausgebildet, der als Druckfeder wirkt. Dieser Vorsprung kann aus einem steifen und/oder federnden Material, wie z.B. Metall oder Kunststoff, ausgebildet sein und erstreckt sich vom austauschbaren Schuhabsatz in Zehenrichtung. Durch die Variabilität von Material und Ausgestaltung des Druckerzeugungselements, insbesondere durch unterschiedliche Länge und Neigung werden das Ausmaß, in dem der Ballenteil der Laufsohle des Schuhsohlenteils angehoben wird und der Gehgrad festgelegt.In a preferred embodiment of the interchangeable shoe heel according to the invention, the pressure generating element is designed as a projection which acts as a compression spring. This protrusion may be made of a stiff and / or resilient material, such as e.g. Metal or plastic, be formed and extends from the interchangeable shoe heel in the toe direction. Due to the variability of material and design of the pressure generating element, in particular by different length and inclination, the extent to which the bale part of the outsole of the shoe sole part is raised and determines the degree of walking.

Unterschiedliche erzielbare Ergebnisse durch unterschiedlich geformte Druckerzeugungselemente des austauschbaren Schuhabsatzes zeigen die Figuren 5 bis 7, wo dasselbe Schuhsohlenteil 2 mit unterschiedlichen Schuhabsätzen 1, die verschieden ausgestaltete Druckerzeugungselemente 1a aufweisen, zu Schuhen 3 von unterschiedlicher Laufsohlenneigung und unterschiedlichem Gehgrad kombiniert ist. Das Druckerzeugungselement 1a wirkt dabei jeweils auf ein Druckübertragungselement 2a in dem Schuhsohlenteil 2, wie weiter unten näher erläutert wird.Different achievable results by differently shaped pressure generating elements of the exchangeable shoe heel show the FIGS. 5 to 7 where the same shoe sole part 2 is combined with different shoe heels 1 having differently designed pressure generating elements 1a to shoes 3 of different outsole inclination and different degree of walking. The pressure generating element 1a acts in each case on a pressure transmission element 2a in the shoe sole part 2, as will be explained in more detail below.

Wie bereits erwähnt, ist bei dem erfindungsgemäßen Schuhsohlenteil zumindest ein Abschnitt des Schuhsohlenteils durch variable Druckausübung des Druckerzeugungselements in Zehenrichtung in seiner Winkelstellung in Bezug auf andere Schuhsohlenteilabschnitte und/oder seine Krümmung veränderbar. Dabei kann das Druckerzeugungselement direkt an einem Schuhsohlenteilabschnitt anliegen. Bevorzugt ist derzeit jedoch eine Ausführungsform, bei der das Schuhsohlenteil ein Druckübertragungselement zur Übertragung von Druck in Zehenrichtung auf zumindest einen Abschnitt des Schuhsohlenteils aufweist. In diesem Fall liegt das Druckerzeugungselement an dem Druckübertragungselement an.As already mentioned, in the shoe sole part according to the invention at least a portion of the shoe sole part is variable by variable pressure exertion of the pressure generating element in the toe direction in its angular position with respect to other shoe sole sections and / or its curvature. In this case, the pressure generating element can rest directly on a shoe sole portion section. However, an embodiment in which the shoe sole part has a pressure transmission element for transmitting pressure in the toe direction to at least one section of the shoe sole part is currently preferred. In this case, the pressure generating element bears against the pressure transmission element.

In einer Variante der Erfindung ist das Druckübertragungselement als eine im Schuhsohlenteil eingebettete Zunge aus einem steifen und/oder federnden Material, wie z.B. Metall oder Kunststoff ausgebildet. In einer alternativen Variante ist das Druckübertragungselement als Luftpolster oder flüssigkeits- oder gelgefüllter Polster ausgebildet. Für beide Ausführungsformen wesentlich ist, dass der vom Druckerzeugungselement des Schuhabsatzes ausgeübte Druck durch das Druckübertragungselement an die gewünschten Stellen im Schuhsohlenteil weitergeleitet wird, wozu bevorzugt das Druckübertragungselement im Schuhsohlenteil verlagerbar angeordnet ist.In a variant of the invention, the pressure transmission element, as a tongue embedded in the shoe sole part, is made of a stiff and / or resilient material, e.g. Metal or plastic formed. In an alternative variant, the pressure-transmitting element is designed as an air cushion or liquid-filled or gel-filled upholstery. For both embodiments, it is essential that the pressure exerted by the pressure generating element of the shoe heel pressure is forwarded by the pressure transmission element to the desired locations in the shoe sole part, for which purpose preferably the pressure transmission element is arranged displaceably in the shoe sole part.

Um die Variabilität des Schuhsohlenteils noch besser steuern zu können, ist in einer Fortbildung der Erfindung zumindest ein sich quer über das Schuhsohlenteil erstreckender Abschnitt mit erhöhter Biegsamkeit bezogen auf dazu benachbarte Schuhsohlenteilabschnitte vorgesehen, wobei in einer bevorzugten Variante sich das Druckübertragungselement und/oder das Druckerzeugungselement in bzw. durch zumindest einen Abschnitt mit erhöhter Biegsamkeit erstreckt/erstrecken.In order to be able to control the variability of the shoe sole part even better, in a further development of the invention at least one portion extending over the shoe sole part with increased flexibility is provided with respect to adjacent shoe sole portions, wherein in a preferred variant the pressure transmission element and / or the pressure generating element in or extend through at least one portion with increased flexibility / extend.

Hervorragende Justierbarkeit, Stabilität und Fixierung des austauschbaren Schuhabsatzes an dem Schuhsohlenteil eines erfindungsgemäßen Schuhs werden erreicht, indem das Schuhsohlenteil mit einem Absatzverbindungselement und der Schuhabsatz mit einem sich damit ergänzenden Sohlenverbindungselement ausgestattet ist. Es kann sich dabei z.B. um ein Schienensystem handeln, oder ein Feder-Nut-System, oder eine Schwalbenschwanzverbindung, oder dergl., wobei auch auf aus dem Stand der Technik bekannte Systeme zurückgegriffen werden kann.Excellent adjustability, stability and fixation of the replaceable shoe heel on the shoe sole portion of a shoe according to the invention are achieved by the shoe sole portion is equipped with a heel connection element and the shoe heel with a complementary sole connecting element. It may be e.g. to act a rail system, or a tongue and groove system, or a dovetail connection, or the like., Wherein also known from the prior art systems can be used.

Die Stabilität des erfindungsgemäßen Schuhs wird weiter erhöht, indem das Schuhsohlenteil zumindest ein Absatzfixierelement aufweist, und der Schuhabsatz ein sich damit ergänzendes Sohlenfixierelement. In der praktischen Ausgestaltung kann es sich dabei um ein Einrastsystem handeln, das vorzugsweise ohne Werkzeug bedienbar sein sollte.The stability of the shoe according to the invention is further increased by the shoe sole part has at least one Absatzfixierelement, and the shoe heel a thus complementary Sohlenfixierelement. In the practical embodiment, it may be a Einrastsystem, which should preferably be operated without tools.

Auf die Figuren 1 bis 4 Bezug nehmend wird der Zusammenbau eines erfindungsgemäßen Schuhs 3 aus einem Schuhsohlenteil 2 und einem Schuhabsatz 1 dargestellt. In der Abfolge der Figuren 1 bis 4 erkennt man dabei deutlich die durch das Verbinden von Schuhsohlenteil 2 und Schuhabsatz 1 ausgelöste individuelle Umgestaltung und Stabilisierung des Schuhs 3 mittels Erzeugung von Druck durch den Schuhsohlenabsatz 1 und Übertragung des Drucks auf den Schuhsohlenteil 2. Wie aus der Zeichnung ersichtlich, weist der Schuhabsatz 1 ein Druckerzeugungselement 1a auf, das in dieser Variante als Fortsatz aus einem steifen, aber biegsamen Material ausgebildet ist und sich vom Schuhabsatz 1 in Zehenrichtung erstreckt. Weiters weist der Schuhabsatz 1 ein Sohlenverbindungselement 1b auf, das beispielsweise als Vorsprünge, Führungsschienen, Nuten o. dergl. ausgebildet sein kann. Schließlich weist der Schuhabsatz 1 fersenseitig auch noch ein Sohlenfixierelement 1c auf, das in dieser Ausführungsform als Vertiefung ausgebildet ist.On the FIGS. 1 to 4 Referring to FIG. 1, the assembly of a shoe 3 according to the invention from a shoe sole part 2 and a shoe heel 1 is shown. In the sequence of FIGS. 1 to 4 can be seen clearly triggered by the connection of shoe sole part 2 and shoe heel 1 individual remodeling and stabilization of the shoe 3 by generating pressure through the shoe sole paragraph 1 and transfer of pressure on the shoe sole part 2. As can be seen from the drawing, the shoe heel 1 a Pressure generating element 1a, which is formed in this variant as an extension of a stiff, but flexible material and extending from the shoe heel 1 in the toe direction. Furthermore, the shoe heel 1 on a sole connection element 1b, which may be formed, for example, as projections, guide rails, grooves o. The like. Finally, the shoe heel 1 on the heel side also has a sole fixing element 1c, which in this embodiment is in the form of a depression.

Das Schuhsohlenteil 2 wiederum umfasst ein Druckübertragungselement 2a zur Übertragung von Druck in Zehenrichtung auf zumindest einen Abschnitt des Schuhsohlenteils 2, in diesem Ausführungsbeispiel auf einen fußballenseitigen Abschnitt 2e und einen mittleren Abschnitt 2d. Der mittlere Abschnitt 2d ist durch geeignete Materialwahl und/oder eine verringerte Sohlenstärke biegsamer als der ballenseitige Abschnitt 2e und ein fersenseitiger Abschnitt 2f. Das Druckübertragungselement 2a ist vorzugsweise als eine im Schuhsohlenteil eingebettete Zunge aus einem steifen Material, wie z.B. Metall oder Kunststoff ausgebildet. Weiters ist das Druckübertragungselement 2a in einem Hohlraum 2g verschiebbar gelagert, wobei sich der Hohlraum 2g von dem fersenseitigen Abschnitt 2f durch den mittleren Abschnitt 2d bis in den ballenseitigen Abschnitt 2e erstreckt, dort gegen eine Endwand des Hohlraums 2g drückt und vorzugsweise auch an dieser Endwand befestigt ist. In einer alternativen Ausführungsform könnte das Druckübertragungselement 2a als Luftpolster oder flüssigkeits- oder gelgefüllter Polster ausgebildet sein. Weiters weist das Schuhsohlenteil 2 ein Absatzverbindungselement 2b auf, in welches das Sohlenverbindungselement 1b des Schuhabsatzes 1 einführbar ist. Schließlich umfasst das Schuhsohlenteil 2 noch ein Absatzfixierelement 2c, das dazu ausgebildet ist, mit dem Sohlenfixierelement 1c des Schuhabsatzes 1 ineinanderzugreifen und eine gegenseitige Arretierung zu bewirken.The shoe sole part 2 in turn comprises a pressure transmission element 2a for transmitting pressure in the direction of toe on at least a portion of the shoe sole part 2, in this embodiment on a foot ball side portion 2e and a middle portion 2d. The middle section 2d is more flexible than the ball-side section 2e and a heel-side section 2f by suitable choice of material and / or a reduced sole thickness. The pressure transmission element 2a is preferably formed as a embedded in the shoe sole part tongue of a rigid material, such as metal or plastic. Further, the pressure transmitting member 2a is slidably supported in a cavity 2g, the cavity 2g extending from the heel-side portion 2f through the middle portion 2d to the bale-side portion 2e, pushing there against an end wall of the cavity 2g, and preferably also attached to this end wall is. In an alternative embodiment, the pressure transmission element 2a could be formed as an air cushion or liquid or gel-filled pad. Furthermore, the shoe sole part 2 has a heel connection element 2b into which the sole connection element 1b of the shoe heel 1 can be inserted. Finally, the shoe sole part 2 also comprises a heel fixing element 2c, which is designed to engage with the sole fixing element 1c of the shoe heel 1 and to effect a mutual locking.

In Fig. 1 ist zu sehen, wie der Schuhabsatz 1 mit seinem Sohlenverbindungselement 1b am Absatzverbindungselement 2b am Fersenboden des Schuhsohlenteils 2 positioniert wird, während gleichzeitig das vordere Ende des Druckerzeugungselements 1a in den fersenseitig offenen, in der Laufsohle eingearbeiteten Hohlraum 2g eingeführt wird, wie durch die beiden Pfeile A, B angedeutet ist.In Fig. 1 It can be seen how the shoe heel 1 is positioned with his sole connecting element 1b on the heel joint 2b on the heel bottom of the shoe sole part 2, while simultaneously the front end of the pressure generating element 1a is inserted into the heel-side, incorporated in the outsole cavity 2g, as shown by the two arrows A, B is indicated.

In Fig. 2 ist die Einrichtung des Gehgrads (Pfeile C, D) und die Anpassung der Ballenstellung (Pfeile E, F) dargestellt, wobei die Zwangsverlagerung des Abschnitts 2f des Schuhsohlenteils 2 nach unten aufgrund der Steifigkeit des schräg nach unten gerichteten Druckerzeugungselements 1a erfolgt, das auf das Druckübertragungselement 2a wirkt. Die Veränderung der Ballenstellung ergibt sich daraus, dass das Drucktragungselement 2a aufgebogen wird. Die Fersenstellung wird durch die individuelle Abschrägung der Oberseite des jeweiligen Absatzes 1 bestimmt.In Fig. 2 the device of the degree of walking (arrows C, D) and the adjustment of the ball position (arrows E, F) is shown, wherein the forced displacement of the portion 2 f of the shoe sole part 2 downwards due to the rigidity of the obliquely downward pressure generating element 1 a, which on the Pressure transmission element 2a acts. The change in the ball position results from the fact that the pressure-bearing element 2a is bent. The heel position is determined by the individual bevel of the top of the respective paragraph 1.

Bei weiterer Vorwärtsbewegung des Druckerzeugungselements 1a stößt dieses gegen das hintere Ende des im Hohlraum befindlichen Druckübertragungselements 2a und erzeugt durch die Vorwärtsbewegung einen in Zehenrichtung gerichteten Druck, der durch die Verlagerbarkeit des Druckübertragungselements 2a im Hohlraum 2g auf den Abschnitt 2e übertragen wird, wie in Fig. 3 dargestellt. Gleichzeitig erzeugt der Abschnitt 2e einen Gegendruck auf das Drucküberzeugungselement 2a, wie durch die gestrichelten Pfeile dargestellt. Dieser Gegendruck führt einerseits dazu, dass sich der Abschnitt 2d des Schuhsohlenteils 2 nach oben durchbiegt, und andererseits das Sohlenfixierelement 1c des Schuhabsatzes 1 und das Absatzfixierelement 2c des Schuhsohlenteils 2 fest ineinander greifen und sich unter Spannung fixieren.Upon further forward movement of the pressure generating element 1a, this abuts against the rear end of the pressure transmitting element 2a located in the cavity and generates by the forward movement in the direction of the toe directed pressure, which is transferred by the displaceability of the pressure transmission element 2a in the cavity 2g to the section 2e, as in Fig. 3 shown. At the same time, the section 2e generates a back pressure on the pressure-convincing element 2a, as shown by the dashed arrows. On the one hand, this counterpressure causes the section 2d of the shoe sole part 2 to bend upwards, and on the other hand the sole fixing element 1c of the shoe heel 1 and the heel fixing element 2c of the shoe sole part 2 firmly engage and fix under tension.

Fig. 4 zeigt diese Endstellung, in der der Absatz 1 und das Schuhsohlenteil 2 unter Spannung in der adaptierten Position gehalten und auf diese Weise im Rahmen des Gesamtschuhs 3 stabilisiert sind. Der erfindungsgemäße Schuh 3 nimmt durch die individuelle Fixierung flexibler Bestandteile positiven Einfluss auf Komfort in Abrollung, Stellung, Standsicherheit, Ruhigstellung von Gelenken und Entlastung, wobei auf alle genannten Parameter durch den Austausch unterschiedlich ausgestalteter Schuhabsätze Einfluss genommen wird und eine gesicherte Absatzstellung gewährleistet wird, die den transformierten Schuh zusätzlich stabilisiert. Fig. 4 shows this end position in which the paragraph 1 and the shoe sole part 2 are held under tension in the adapted position and are stabilized in this way in the context of the overall shoe 3. The shoe 3 according to the invention by the individual fixation of flexible components positive influence on comfort in unwinding, position, stability, immobilization of joints and relief, with all the above parameters influenced by the exchange differently designed heels and ensures a secure sales position is guaranteed additionally stabilizes the transformed shoe.

Es sei nochmals darauf hingewiesen, dass im Gegensatz zum Stand der Technik bei den erfindungsgemäßen Ausführungsformen des Schuhs der Absatz 1 eine aktive Rolle bei der Transformation des Schuhs spielt, indem er nicht nur einfach am Schuhsohlenteil 2 befestigt wird, sondern beim Vorgang der Befestigung über das Druckerzeugungselement 1a und das Druckübertragungselement 2a eine Transformation von Ballenstellung, Gehgrad, etc. bewirkt.It should again be noted that, in contrast to the prior art in the embodiments of the shoe according to the invention, the paragraph 1 plays an active role in the transformation of the shoe by not simply attached to the shoe sole part 2 is, but in the process of attachment via the pressure generating element 1 a and the pressure transmission element 2 a causes a transformation of ball position, degree, etc.
