Description

Die vorliegende Erfindung bezieht sich auf eine Schuhsohle gemäß dem Oberbegriff des Anspruchs 1 und auf einen Schuh mit einer derartigen Schuhsohle.The present invention relates to a shoe sole according to the preamble of claim 1 and with a shoe such a shoe sole.

Eine Schuhsohle gemäß dem Oberbegriff des Anspruchs 1 ist aus der DE-PS 189777 bekannt. Diese Schuhsohle dient dazu, die Schuhgröße in einem begrenzten Bereich einstellen zu können. Dort erstreckt sich die Vordersohle mit einem an den Gelenkbereich anschließenden Abschnitt bis in die hintere Hälfte des mit einem Schlitz versehenen Absatzes. Am Ende des hinteren Abschnitts der Vordersohle ist in einer Bohrung eine Gewindehülse angebracht. In diese ist eine Einstellspindel eingeschraubt, die sich von einer Öffnung an der Absatzhinterkante aus in die Bohrung der Vordersohle hinein bis etwa zum Absatzfrontbereich erstreckt.A shoe sole according to the preamble of claim 1 is made of DE-PS 189777 known. This shoe sole serves to keep the shoe size in a limited Range. There extends the Front sole with one adjoining the joint area Section down to the back half of the slot provided paragraph. At the end of the rear section of the A threaded sleeve is attached to the front sole in a hole. An adjustment spindle is screwed into this, which extends from an opening in the trailing edge of the hole in the Front sole extends approximately to the heel front area.

Die Einstellspindel ragt über die Absatzhinterkante hinaus. Sie besitzt im Bereich der hinteren Absatzwand eine Ringnut, in die eine in der Absatzwand eingesetzte Führungplatte eingreift. Mittels der Führungsplatte und der Ringnut der Einstellspindel ist diese in der Absatzwand drehbar und unverschiebbar gelagert. Beim Drehen der Einstellspindel über einen über die Absatzhinterkante überstehenden Kopf wird der hintere Abschnitt der Vordersohle je nach Drehrichtung in den Absatz hineingezogen oder aus diesem herausgeschoben. Dadurch kann die Größe des Schuhes kontinuierlich verstellt werden.The adjusting spindle protrudes beyond the rear edge of the heel. she has an annular groove in the area of the rear heel wall, into which a guide plate inserted in the heel wall engages. Using the guide plate and the ring groove of the adjusting spindle it is rotatable and immovable in the heel wall stored. When turning the adjustment spindle via a The rear section protruding behind the heel becomes the rear section depending on the direction of rotation in the heel pulled in or pushed out of it. This allows the The size of the shoe can be adjusted continuously.

Beim Laufen wird bekanntlich der Absatz an dessen Hinterkante mit dem größten Auftrittsdruck belastet. Es entsteht daher dort eine hohe Belastung des Absatzmaterials im Bereich der Führungsplatte. Dadurch wird die den ganzen Absatz durchziehende Einstellspindel beim Auftreten, insbesondere im hinteren Bereich, sehr stark auf Biegung belastet. Der Gelenkbereich der Vordersohle ist bei dieser Sohlenausführung nicht dehnbar ausgestaltet.As is known, when running, the heel is at the rear edge burdened with the greatest performance pressure. It therefore arises there a high load of sales material in the area of Guide plate. This will make the whole paragraph pulling adjustment spindle when occurring, especially in rear area, very heavily loaded on bending. Of the The joint area of the front sole is in this sole version not designed to be stretchy.

Mit der vorliegenden Erfindung soll die Aufgabe gelöst werden, eine Schuhsohle der genannten Art derart weiterzubilden, daß das Absatzmaterial an der Hinterkante nicht mehr so stark druckbelastet und auf die Einstellspindel kein oder nur noch ein vernachlässigbares Biegemoment ausgeübt wird.The object of the present invention is to be achieved to develop a shoe sole of the type mentioned in such a way that the heel material on the rear edge is no longer as strong under pressure and no or only on the adjusting spindle a negligible bending moment is exerted.

Gelöst wird diese Aufgabe durch die Merkmale des Anspruchs 1.This object is achieved by the features of claim 1.

Gemäß der Erfindung kann in der kleinsten einstellbaren Schuhgröße der Kopf der Einstellspindel von innen praktisch unmittelbar an dem hinteren Widerlager anliegen, so daß der Absatz nicht von der Einstellspindel durchsetzt ist und wie ein üblicher Absatz funktioniert. In der größten einstellbaren Schuhgröße ragt die Einstellspindel maximal etwa bis zu 2/3 nach hinten in den Absatz hinein. Es tritt aber auch hierbei keine hohe Belastung des Absatzmaterials im Bereich der hinteren Absatzkante auf, so daß der Materialverschleiß dort gegenüber der aus der DE-PS 189777 bekannten Anordnung stark vermindert ist. According to the invention can be adjusted in the smallest Shoe size the head of the adjusting spindle practical from the inside rest directly on the rear abutment, so that the Paragraph is not penetrated by the adjusting spindle and like a usual paragraph works. In the largest adjustable The adjusting spindle protrudes a maximum of up to 2/3 back into the paragraph. But it also occurs here no high load on the sales material in the area of rear heel edge so that the material wear there strong compared to the arrangement known from DE-PS 189777 is reduced.

In den Fig. 1 bis 6 ist mit 1 eine Schuhsohle bezeichnet, die aus einer Vordersohle oder aus einem Vordersohlenabschnitt 2, einer Hintersohle oder aus einem Hintersohlenabschnitt 3 und aus einem Gelenkabschnitt 4 besteht. Der Gelenkabschnitt 4 erstreckt sich über oder annähernd über den Gelenkbereich 4'.1 to 6, 1 denotes a shoe sole, the from a front sole or from a front sole section 2, a rear sole or from a rear sole section 3 and consists of a joint section 4. The joint section 4 extends over or approximately over the joint area 4 '.

Die einzelnen Sohlenabschnitte 2, 3, 4 können aus einem einheitlichen, homogenen Bauteil, z.B. aus einem einzigen Form- oder Spritzteil bestehen oder der Gelenkabschnitt 4 kann einerseits am hinteren Endbereich 5 der Vordersohle 2 und andererseits am Frontbereich 6 der Hintersohle 3 befestigt, z.B. angenäht und/oder angeklebt oder - auch unter Verwendung eines anderen Materials als das der Vorder- und/oder Hintersohlenabschnitte 2, 3 - angeformt sein.The individual sole sections 2, 3, 4 can be made from one uniform, homogeneous component, e.g. from a single shape or Injection molded part or the joint section 4 can on the one hand at the rear end area 5 of the front sole 2 and on the other hand attached to the front area 6 of the rear sole 3, e.g. sewn on and / or glued or - also using of a different material than that of the front and / or Rear sole sections 2, 3 - be molded.

Im Endbereich 5 der Vordersohle 2 sowie im Frontbereich 6 der Hintersohle 3 ist je ein Widerlager 7 bzw. 8 vorgesehen, die jeweils mit der Schuhsohle 1 oder mit den betreffenden Abschnitten 2, 3 eine bauliche Einheit bilden oder an dieser bzw. diesen befestigt, beispielsweise angeklebt, angeformt oder anderweitig miteinander verbunden sind. Die Widerlager 7, 8 können aus einem insbesondere stabileren Material als die anderen Schuhsohlenteile 2, 3, 4 hergestellt sein.In the end area 5 of the front sole 2 and in the front area 6 of the Rear sole 3 is provided with an abutment 7 and 8, respectively each with the shoe sole 1 or with the relevant Sections 2, 3 form a structural unit or on this or attached, for example glued, molded or are otherwise connected to each other. The abutments 7, 8 can be made of a more stable material than that other shoe sole parts 2, 3, 4 be made.

Im hinteren Widerlager 8, das beispielsweise durch eine Aussparung 9 in einem Block gebildet ist, ist eine Mutternscheibe 10 oder ein Steg mit einer Gewindebohrung eingesetzt. In diese Gewindebohrung ist ein als Gewindebolzen ausgebildetes Stellmittel 11 mit seinem hinteren Gewindeabschnitt 11.1 von der Rückwand 12 des Fersenteils 13 oder eines Absatzes durch eine dort vorgesehene Aussparung 14 oder durch einen Schlitz, eingeschraubt. Wie anhand der Fig. 2 ersichtlich, ragt der Kopf des Stellmittels 11 bei kleinster Schuhgrößeneinstellung vom Widerlager 8 aus etwa 2/3 in den Absatz 3 hinein. Bei größter Einstellung der Schuhgröße kann der Kopf am Widerlager 8 anliegen und ragt daher praktisch nicht mehr in den Absatz hinein. Beim Auftreten wird also der Absatz in diesem Zustand wie ein üblicher Absatz belastet.In the rear abutment 8, for example by a Recess 9 is formed in a block is one Nut washer 10 or a web with a threaded hole used. In this threaded hole is a threaded bolt trained adjusting means 11 with its rear Thread section 11.1 from the rear wall 12 of the heel part 13 or a paragraph through a recess 14 provided there or screwed in through a slot. As with FIG. 2 can be seen, the head of the adjusting means 11 projects at the smallest Shoe size adjustment from abutment 8 from about 2/3 in Paragraph 3 into it. With the largest setting of the shoe size can the head abut the abutment 8 and therefore protrudes practically no longer into the paragraph. So when it occurs, the Paragraph in this state is charged like a normal paragraph.

Das nach vorn ragende Ende 15 des Stellmittels 11 greift in ein in Richtung des Stellmittels 11 verlaufendes, hinten offenes Sackloch 16 des vorderen Widerlagers 7 ein.The forward end 15 of the actuating means 11 engages in the direction of the actuating means 11, open at the rear Blind hole 16 of the front abutment 7.

Der Gelenkabschnitt 4 des Ausführungsbeispiels gemäß den Fig. 1 bis 4 ist durch eine wellenförmig gefaltete Bahn gebildet, deren Wellenberge 17 und Wellentäler 18 quer zur Sohlenlängsachse 19, insbesondere senkrecht oder etwa senkrecht zu dieser verlaufen. Diese Form ist üblicherweise aber nicht durch Faltung gebildet, sondern wird unmittelbar, beispielsweise durch einen Spritz- oder Spritzgießprozeß, in dieser Form hergestellt.The joint section 4 of the exemplary embodiment according to FIG. 1 to 4 is formed by a wave-folded sheet, whose wave crests 17 and troughs 18 across Longitudinal longitudinal axis 19, in particular perpendicular or approximately perpendicular run to this. This form is usually not formed by folding, but is immediately, for example by an injection or injection molding process, in made this shape.

Vorzugsweise verläuft das Stellmittel 11 in oder etwa in Richtung der Längsachse 19 der Schuhsohle 1. Das Stellmittel 11 ist durch Öffnungen 20 der einzelnen durch die Faltung gebildeten Wandteile 21 des Gelenkabschnitts 4 hindurchgesteckt.The adjusting means 11 preferably runs in or approximately in Direction of the longitudinal axis 19 of the shoe sole 1. The adjusting means 11 is through openings 20 of each by folding formed wall parts 21 of the joint section 4 inserted.

Die Sohlenabschnitte 2, 3 und 4 bestehen bevorzugt aus elastisch nachgiebigem oder federndem Material. Beim Ausführungsbeispiel gemäß den Fig. 1 bis 3 ist der Gelenkabschnitt 4 derart geformt, daß er eine Minimallänge einnimmt, in der das Stellmittel 11, beispielsweise ohne Druckbelastung, eingreift. Diese Lage zeigen die Fig. 1 und 2.The sole sections 2, 3 and 4 preferably consist of resilient or resilient material. At the Embodiment according to FIGS. 1 to 3 is the Joint section 4 shaped so that it is a minimum length occupies in which the adjusting means 11, for example without Pressure load, engages. 1 and 2.

Wird das Stellmittel 11 durch Drehen weiter in die Mutternscheibe 10 hineingeschraubt, also in der Zeichenebene nach links verstellt, dann drückt das freie Ende 15 des Stellmittels 11 gegen den Boden des Sackloches 16 im Widerlager 7. Dadurch wird dieses Widerlager 7 vom Widerlager 8 wegbewegt und dadurch der Gelenkabschnitt 4 gedehnt. Somit wird auch der Gelenkbereich 4' verlängert und die gesamte Schuhsohlenlänge vergrößert. Dieser vergrößerte Fall ist in der Fig. 3 dargestellt.If the actuating means 11 is turned further into the Nut washer 10 screwed in, that is in the drawing plane adjusted to the left, then pushes the free end 15 of the Setting means 11 against the bottom of the blind hole 16 in the abutment 7. As a result, this abutment 7 from the abutment 8th moved away and thereby the joint section 4 stretched. Thus the joint area 4 'is also extended and the whole Increased shoe sole length. This enlarged case is in the Fig. 3 shown.

Durch Zurückschrauben des Stellmittels 11, beispielsweise in die Ausgangslage, nimmt der Gelenkabschnitt 4 infolge seines materialbedingten Rückstellmoments wieder seine ursprüngliche Form und Lage ein.By unscrewing the adjusting means 11, for example in the starting position, the joint section 4 takes due to its material-related restoring torque back to its original Shape and location.

Auf diese Weise kann eine Schuhsohle 1 und ein mit dieser versehener Schuh sehr einfach und schnell auf unterschiedliche Größen und/oder sonstige Bedürfnisse des Fußes eingestellt werden.In this way, a shoe sole 1 and one with this provided shoe very easily and quickly on different Sizes and / or other needs of the foot set become.
