Description

Die vorliegende Erfindung betrifft einen Schnellspannverschluss für einen Schnürschuh, gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a quick release fastener for a lace-up shoe, according to the preamble of claim 1.

WO 2009/055855 A1 offenbart einen Schnellspannverschluss für einen Schnürschuh mit den Merkmalen des Oberbegriffs des Anspruchs 1. WO 2009/055855 A1 discloses a quick release fastener for a lace-up shoe with the features of the preamble of claim 1.

Verschlüsse für Schuhe sind in unterschiedlichen Ausführungsformen bekannt. Sie haben einerseits die Funktion, den Schuh sicher am Fuß zu halten, sollen jedoch andererseits unkompliziert, schnell und bequem zu öffnen und zu schließen sein. Neben Klettverschlüssen, die in den letzten Jahren zunehmende Beliebtheit erfahren, werden die meisten Schuhe nach wie vor durch die bewährten Schnürsenkel geschnürt. Eine Schnürung bietet den Vorteil, dass der Schuh sicher und bequem am Fuß sitzt, und wird auch aus ästhetischen Gründen häufig vorgezogen.Closures for shoes are known in different embodiments. On the one hand, they have the function of holding the shoe securely on the foot, but on the other hand, they should be easy, quick and easy to open and close. In addition to Velcro fasteners, which have become increasingly popular in recent years, most shoes are still laced using the tried and tested shoelaces. Lacing offers the advantage that the shoe sits securely and comfortably on the foot and is often preferred for aesthetic reasons.

Das Öffnen und Schließen der Schnürung ist vergleichsweise zeitaufwendig und kompliziert, insbesondere für Personen mit eingeschränkten manuellen Fähigkeiten. Es sind Klemmsicherungen bekannt, in welche die beiden freien Enden der Schnürsenkel eingefädelt werden und festgezogen werden, so dass sie sich nur durch Entriegeln einer Sperre wieder lösen lassen. Derartige Schnellspannverschlüsse ersetzen zwar eine Schleife oder einen Knoten als Sicherung, tragen jedoch nicht zu einer Vereinfachung des Spannens und Lösens der eigentlichen Schnürung bei.Opening and closing the lacing is comparatively time-consuming and complicated, especially for people with limited manual skills. There are known clamping locks into which the two free ends of the shoelaces are threaded and tightened so that they can only be released again by unlocking a lock. Such quick-release fasteners replace a loop or a knot as a backup, but do not contribute to a simplification of the tensioning and loosening of the actual lacing.

US 6 671 980 B1 offenbart einen Schnellspannverschluss, der fest auf einer Lasche eines Schnürschuhs befestigt ist und ein feststehendes Element umfasst, dass durch einen Niet oder dergleichen mit der Lasche verbunden ist, sowie ein bewegliches Element, das schwenkbar mit dem feststehenden Element verbunden ist. Durch eine auf dem beweglichen Element angebrachte Öse ist der Schnürsenkel gefädelt, derart, dass das bewegliche Element durch eine Schwenkbewegung auf das feststehende Element bzw. auf die Lasche den Schnürsenkel spannt. US 6 671 980 B1 discloses a quick release fastener which is fixedly attached to a tab of a lace-up shoe and comprises a fixed element that is connected to the tab by a rivet or the like, and a movable element that is pivotably connected to the fixed element. The shoelace is threaded through an eyelet attached to the movable element in such a way that the movable element tensions the shoelace by means of a pivoting movement on the fixed element or on the tab.

Dieser bekannte Schnellspannverschluss weist jedoch den Nachteil auf, dass er sich nicht zerstörungsfrei vom Schuh lösen lässt, wenn seine Verwendung nicht erwünscht ist. Ebenso wenig lässt sich ein solcher Schnellspannverschluss nachträglich an einem Schuh anbringen oder an verschiedene Schuhe anpassen. Darüber hinaus ist es erwünscht, dass der Verschlussmechanismus verdrehsicher an der Lasche sitzt. Dies ist zumindest in der Lösung, die in US 6 671 980 B1 dargestellt ist, nicht ohne weiteres gewährleistet, da dort nur ein einziger Niet zur Befestigung auf der Lasche vorgesehen ist, um welchen der Schnellspannverschluss sich bei Belastung drehen kann. Ein Verdrehen kann hier nur durch zusätzliche Befestigungsmittel wie z.B. einen zusätzlichen Niet verhindert werden. Der ohnehin bereits sehr aufwändig konstruierte Verschluss würde hierdurch noch komplizierter werden.However, this known quick release fastener has the disadvantage that it cannot be detached from the shoe in a non-destructive manner if its use is not desired. Such a quick release fastener cannot be retrofitted to a shoe or adapted to different shoes. In addition, it is desirable that the locking mechanism sits on the tab so that it cannot rotate. This is at least in the solution included in US 6 671 980 B1 is not guaranteed, since there is only a single rivet for fastening on the tab, around which the quick release fastener can rotate when loaded. Twisting can only be prevented here by additional fastening means such as an additional rivet. The closure, which is already very elaborately designed, would become even more complicated as a result.

Es ist daher eine Aufgabe der vorliegenden Erfindung, einen Schnellspannverschluss für einen Schnürschuh zu schaffen, der die Zugspannung der Schnürung auf möglichst einfache und bequeme Weise lösen lässt und sich in der gespannten Position einfach verriegeln lässt, und zwar mit möglichst wenigen Handgriffen, wobei die Schnürung im gespannten Zustand ebenso sicher gehalten werden soll wie eine herkömmliche Schnürung ohne Schnellspannverschluss. Eine weitere Aufgabe besteht darin, einen solchen Schnellspannverschluss derart auszubilden, dass er ohne weiteres bei Bedarf vom Schuh zu lösen ist und sich auch nachträglich an einem gewöhnlichen Schuh anbringen lässt, ohne dass der Sitz der Schnürung sich bei Belastung verändert.It is therefore an object of the present invention to create a quick release fastener for a lace-up shoe which can release the tension of the lacing in the simplest and most convenient way possible and which can be locked in the tensioned position with as few movements as possible, with the lacing should be held just as securely when tensioned as a conventional lacing system without a quick-release fastener. Another object is to design such a quick-release fastener in such a way that it can be easily detached from the shoe if necessary and can also be retrofitted to an ordinary shoe without the fit of the lacing changing under load.

Diese Aufgabe wird erfindungsgemäß durch einen Schnellspannverschluss mit den Merkmalen des Anspruchs 1 gelöst.According to the invention, this object is achieved by a quick release fastener with the features of claim 1.

Der erfindungsgemäße Schnellspannverschluss umfasst ein Basiselement zur Anbringung an einer Lasche des Schnürschuhs, das seitlich von einer freien Kante der Lasche her auf diese aufsteckbar ist und mit einem Befestigungsmittel zur lösbaren Befestigung an oder in einer der Schnürösen der Lasche versehen ist. Mit diesem Basiselement ist ein Spannelement um eine Schwenkachse schwenkbar verbunden. Auf diese Weise ist das Spannelement zwischen einer geschlossenen Stellung, in der es auf das Basiselement geklappt ist, und einer offenen Stellung klappbar. Verriegelungsmittel dienen zum Halten des Spannelements in der geschlossenen Stellung, so dass es sich nicht ohne weiteres lösen und den Schnellspannverschluss öffnen kann. Im Abstand von der Schwenkachse ist im Spannelement mindestens eine Öse vorgesehen, die zur Durchführung eines Schnürsenkels dient.The quick release fastener according to the invention comprises a base element for attachment to a tab of the lace-up shoe, which can be attached laterally from a free edge of the strap and is provided with a fastening means for detachable attachment to or in one of the lacing eyes of the strap. With this basic element is a clamping element pivotally connected about a pivot axis. In this way, the tensioning element can be folded between a closed position, in which it is folded onto the base element, and an open position. Locking means are used to hold the clamping element in the closed position, so that it cannot easily come loose and open the quick release fastener. At a distance from the pivot axis, at least one eyelet is provided in the tensioning element, which is used to pass through a shoelace.

Der Schnellspannverschluss lässt sich abnehmbar an einer der beiden Laschen eines gewöhnlichen Schuhs anbringen, die jeweils eine Reihe von Schnürösen tragen. Bei einem herkömmlichen Schuh wird der Schnürsenkel wechselweise durch die rechts und links am Schuh gegenüberliegenden Schnürösen in den jeweiligen Laschen gezogen, anschließend festgezurrt und beispielsweise mittels einer Schleife verknotet. Ein erfindungsgemäßer Schnellspannverschluss lässt sich derart an einer dieser beiden Laschen anbringen, dass das Befestigungsmittel in eine Schnüröse einer Lasche eingreift und somit das Basiselement festlegt. Die Schwenkachse, die das Spannelement mit dem Basiselement verbindet, liegt dann an oder in der Nähe einer freien Kante dieser Lasche an, so dass das Spannelement in der geschlossenen Stellung auf der Lasche aufliegt und sich beim Öffnen von dieser Lasche nach oben in Richtung der anderen, am Schuh gegenüberliegenden Lasche schwenken lässt.The quick release fastener can be detachably attached to one of the two tabs of an ordinary shoe, each of which has a series of lace eyelets. In a conventional shoe, the shoelace is alternately pulled through the eyelets opposite on the right and left of the shoe in the respective tabs, then lashed and knotted, for example, by means of a loop. A quick release fastener according to the invention can be attached to one of these two tabs in such a way that the fastening means engages in a lacing loop of a tab and thus fixes the base element. The pivot axis, which connects the tensioning element to the base element, then rests on or near a free edge of this flap, so that the tensioning element rests on the flap in the closed position and moves upwards from this flap towards the other when it is opened can pivot on the opposite flap on the shoe.

Eine der Ösen ist somit durch das Befestigungsmittel belegt. Sie wird in ihrer Funktion durch die Öse im Spannelement ersetzt. Der Schnürsenkel wird auf der Seite des Schuhs, die dem Schnellspannverschluss gegenüberliegt, durch die Ösen der dort befindlichen Lasche gezogen, auf der Seite des Schnellspannverschlusses jedoch durch die Öse im Spannelement, sowie gegebenenfalls noch durch weitere Ösen, die durch den Schnellspannverschluss nicht belegt werden. Im Rahmen der vorliegenden Erfindung können im Spannelement gegebenenfalls auch mehrere Ösen zum Durchfädeln des Schnürsenkels vorgesehen sein.One of the eyelets is thus occupied by the fastening means. Its function is replaced by the eyelet in the tensioning element. On the side of the shoe opposite the quick release fastener, the shoelace is pulled through the eyelets of the tab located there, on the side of the quick release fastener, however, through the eyelet in the clamping element and, if necessary, through further eyelets that are not occupied by the quick release fastener. Within the scope of the present invention, several eyelets for threading through the shoelace can optionally also be provided in the tensioning element.

Es werden somit die ohnehin an einem Schnürschuh vorhandenen Ösen zur Befestigung genutzt, so dass sowohl eine Nachrüstung eines üblichen Schuhs als auch ein rückstandsfreies Entfernen des erfindungsgemäßen Schnellspannverschlusses vom Schuh möglich sind. In der am Schuh angebrachten Position sitzt der Schnellspannverschluss dennoch verdrehsicher an der Lasche, da durch die Anlage der Schwenkachse an oder nahe an der freien Kante der Lasche das Basiselement in seiner Lage festgelegt wird und sich nicht mehr um das Befestigungsmittel drehen kann.The eyelets already present on a lace-up shoe are thus used for fastening, so that both a retrofitting of a conventional shoe and a residue-free removal of the quick release fastener according to the invention from the shoe are possible. In the position attached to the shoe, the quick release fastener is non-rotatably seated on the tab, since the base element is fixed in its position by the system of the pivot axis on or close to the free edge of the tab and can no longer rotate around the fastening means.

Im Gebrauchszustand liegt bei geschlossenem Schnellspannverschluss das Spannelement auf der Lasche auf, auf welche das Basiselement aufgesteckt ist, und der Schnürsenkel ist in dieser Position festgezurrt und verknotet. Zum Lösen des Schnellspannverschlusses werden die Verriegelungsmittel gelöst, so dass das Spannelement von der Lasche bzw. dem Basiselement hochgeklappt werden kann. Hierdurch verringert sich der Abstand zwischen der oder den Ösen im Spannelement und den gegenüberliegenden Ösen an der freien, nicht durch den Schnellspannverschluss belegten Lasche des Schuhs. Dies bewirkt ein Lösen der Zugspannung des Schnürsenkels quer über den Schuh hinweg, ohne dass der Knoten gelöst werden muss. In umgekehrter Weise wird zum Verschließen des Schnellspannverschlusses das Spannelement wieder auf das Basiselement geklappt, und die Verriegelungsmittel greifen wieder ineinander ein. Diese Verriegelungsmittel sind vorteilhaft so zu gestalten, dass sie sich von Hand relativ leicht lösen lassen, also mit einem gewissen Kraftaufwand, ein versehentliches Lösen jedoch verhindert wird.In the state of use, when the quick-release fastener is closed, the tensioning element rests on the flap onto which the base element is attached, and the shoelace is lashed and knotted in this position. To release the quick release fastener, the locking means are released so that the clamping element can be folded up from the tab or the base element. This reduces the distance between the eyelet or eyelets in the tensioning element and the opposing eyelets on the free tab of the shoe that is not occupied by the quick release fastener. This causes the tension of the shoelace to be released across the shoe without the knot having to be undone. Conversely, to close the quick release fastener, the clamping element is folded back onto the base element, and the locking means again engage one another. These locking means are advantageously designed in such a way that they can be released relatively easily by hand, that is to say with a certain amount of force, while inadvertent release is prevented.

Zum Öffnen und Schließen des Schnellspannverschlusses muss somit lediglich das Spannelement aus der Verriegelung gelöst bzw. wieder auf das Basiselement geschwenkt werden. Dies kann durch einen einfachen Handgriff geschehen. Die Bedienung ist einfach und unkompliziert. Falls gewünscht, kann der Schnellspannverschluss vom Schuh abgenommen werden, in dem das Befestigungselement gelöst wird und anschließend das Basiselement einfach von der Lasche abgezogen wird.To open and close the quick release fastener, the clamping element only needs to be released from the lock or pivoted back onto the base element. This can be done with a simple movement. Operation is simple and straightforward. If desired, the quick release fastener can be removed from the shoe by releasing the fastening element and then simply pulling the base element off the tab.

Vorzugsweise umfasst das Befestigungsmittel einen Stift, der von der Rückseite des Basiselements, die dem Spannelement in der geschlossenen Stellung gegenüberliegt, in dieses Basiselement lösbar eingesetzt ist. Der Stift lässt sich durch eine Schnüröse durchführen, an welcher das Basiselement dann gehalten wird.The fastening means preferably comprises a pin which is detachably inserted into this base element from the rear side of the base element, which is opposite the tensioning element in the closed position. The pin can be passed through a lacing loop on which the base element is then held.

Weiter vorzugsweise ist der Stift in ein Innengewinde im Basiselement eingeschraubt. Zu diesem Zweck ist der Stift an seinem Ende mit einem entsprechenden Außengewinde versehen.More preferably, the pin is screwed into an internal thread in the base element. For this purpose, the pin is provided with a corresponding external thread at its end.

Weiter vorzugsweise umfasst das Basiselement eine Reihe mehrerer Innengewinde mit verschiedenen Abständen zur Schwenkachse. Durch Wahl eines Innengewindes lässt sich somit der Abstand der Schwenkachse vom Befestigungsmittel anpassen, so dass eine Anpassung an einen Abstand einer Kante der Lasche, an welcher die Schwenkachse anliegen soll, und der Schnüröse anpassbar ist.Furthermore, the base element preferably comprises a number of several internal threads at different distances from the pivot axis. By choosing an internal thread, the distance between the pivot axis and the fastening means can thus be adapted, so that an adjustment to a distance between an edge of the tab on which the pivot axis is to rest and the lacing eyelet can be adapted.

Gemäß der vorliegenden Erfindung umfasst das Basiselement einen im wesentlichen U-förmigen Körper zum seitlichen Aufschieben auf die Lasche, und die Schwenkachse ist an einem Ende des Basiselements angebracht, an welchem die Schenkel zusammenlaufen. Das Basiselement lässt sich somit in diesem Fall derart auf die Lasche aufschieben, dass einer seiner Schenkel außen auf der Vorderseite der Lasche aufliegt, während der andere Schenkel an der innenliegenden Rückseite anliegt. Die Schenkel umgreifen die Lasche somit nach Art eines Bügels oder Clips. Bei entsprechender Positionierung des Basiselements auf der Schnüröse lässt sich dann das Befestigungsmittel zum Fixieren des Basiselements in seiner Position einsetzen.According to the present invention, the base element comprises a substantially U-shaped body for sliding laterally onto the tab, and the pivot axis is attached to one end of the base element at which the legs converge. In this case, the base element can thus be pushed onto the flap in such a way that one of its legs rests on the outside of the front side of the flap, while the other leg rests on the inside rear side. The legs thus encompass the tab in the manner of a bracket or clip. With appropriate positioning of the base element on the lace eyelet, the fastening means can then be used to fix the base element in its position.

Weiter vorzugsweise durchquert der Stift in diesem Fall den freien Zwischenraum zwischen den Schenkeln, also beispielsweise in der Nähe der freien Enden der Schenkel in ausreichendem Abstand zur Schwenkachse, entsprechend einem Abstand der Schnüröse von einer Kante der Lasche.In this case, the pin also preferably traverses the free space between the legs, for example in the vicinity of the free ends of the legs at a sufficient distance from the pivot axis, corresponding to a distance between the lace eyelet and an edge of the flap.

Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung umfassen die Verriegelungsmittel Rastmittel, die eine von Hand lösbare Verrastung des Spannelements mit dem Basiselement in der geschlossenen Stellung ermöglichen.According to a further preferred embodiment of the invention, the locking means comprise latching means which enable the tensioning element to be manually releasably latched to the base element in the closed position.

Vorzugsweise umfasst das Spannelement eine Ausnehmung zur Aufnahme des Basiselements in der geschlossenen Stellung. In diesem Fall bildet das Spannelement mit dem Basiselement in der geschlossenen Stellung eine Einheit, und die Dicke des Schnellspannverschlusses auf der Oberseite der Lasche wird begrenzt.The tensioning element preferably comprises a recess for receiving the base element in the closed position. In this case, the clamping element forms a unit with the base element in the closed position, and the thickness of the quick-release fastener on the top of the tab is limited.

Vorzugsweise weist das Basiselement an seiner Oberseite eine Verdickung auf, die beim Schließen des Spannelements in dessen Ausnehmung eingeclipst wird. Dies wird beispielsweise durch eine gewisse Elastizität des Materials des Spannelements ermöglicht, welches sich beim Schließen leicht aufspreizt, so dass die Verdickung des Basiselements den Öffnungsquerschnitt passieren kann. Die Verdickung kann beispielsweise einen Querschnitt aufweisen, der wie ein Schwalbenschwanz geformt ist und an seiner Oberseite die maximale Breite aufweist, jedoch zur Rückseite hin etwas zusammenläuft. Ferner ist es möglich, dass die Verdickung lediglich an einer Stelle zwischen der Schwenkachse und dem Befestigungsmittel angebracht ist, derart, dass der Querschnitt des Basiselements über den Abstand zwischen der Schwenkachse und dem Befestigungsmittel variiert.The base element preferably has a thickening on its upper side, which is clipped into its recess when the clamping element is closed. This is made possible, for example, by a certain elasticity of the material of the tensioning element, which spreads slightly when closing, so that the thickening of the base element can pass the opening cross-section. The thickening can, for example, have a cross-section which is shaped like a dovetail and has the maximum width on its upper side, but converges slightly towards the rear. Furthermore, it is possible that the thickening is attached only at one point between the pivot axis and the fastening means, in such a way that the cross section of the base element varies over the distance between the pivot axis and the fastening means.

Die vorliegende Erfindung betrifft ferner einen Schnürschuh, umfassend einen Schnellspannverschluss der oben beschriebenen Art.The present invention also relates to a lace-up shoe comprising a quick release fastener of the type described above.

Vorzugsweise umfasst dieser Schnürschuh eine Lasche, die mit einer Anzahl von Schnürösen versehen ist, wobei der Schnellspannverschluss derart an der Lasche angebracht ist, das Basiselement seitlich von einer freien Kante der Lasche her auf die Lasche aufgesteckt ist, das Befestigungsmittel des Basiselements im aufgesteckten Zustand lösbar in eine Schnüröse eingesetzt ist und die Schwenkachse an oder in der Nähe der freien Kante der Lasche anliegt, so dass das Spannelement in der geschlossenen Stellung auf der Lasche aufliegt. Im folgenden wird ein bevorzugtes Ausführungsbeispiel der vorliegenden Erfindung anhand der Zeichnung näher erläutert.

Fig. 1 zeigt einen Schnellspannverschluss 10 für einen hier nicht näher dargestellten Schnürschuh. Der Schnellspannverschluss 10 ist dazu vorgesehen, an einer Lasche des Schnürschuhs angebracht zu werden, die mit einer Anzahl von Schnürösen versehen ist, durch welche ein Schnürsenkel gefädelt werden kann. Fig. 1 zeigt den Schnellspannverschluss 10 in der geöffneten Stellung. Er umfasst ein Basiselement 12, das dazu vorgesehen ist, abnehmbar an der nicht dargestellten Lasche des Schnürschuhs befestigt zu werden. Zu diesem Zweck umfasst das Basiselement 12 einen Stift 14 als Befestigungsmittel, der von der Rückseite her in ein Innengewinde 16 im Basiselement 12 eingeschraubt ist. Bei der Anwendung wird das Basiselement 12 seitlich so auf der Lasche aufgesteckt, dass der Stift 14 von der Rückseite der Lasche her durch eine Schnüröse geführt und in das Innengewinde 16 eingeschraubt wird. Fig. 1 shows a quick release fastener 10 for a lace-up shoe, not shown here. The quick release fastener 10 is intended to be attached to a tab of the lace-up shoe which is provided with a number of lace eyelets through which a shoe lace can be threaded. Fig. 1 shows the quick release fastener 10 in the open position. It comprises a base element 12, which is provided to be detachably attached to the tab, not shown, of the lace-up shoe. For this purpose, the base element 12 comprises a pin 14 as a fastening means, which is screwed into an internal thread 16 in the base element 12 from the rear. During use, the base element 12 is placed on the side of the tab in such a way that the pin 14 is passed through a lacing eyelet from the rear of the tab and screwed into the internal thread 16.

Außer dem Innengewinde 16, in welches in der Darstellung in Fig. 1 der Stift 14 eingeschraubt ist, umfasst das Basiselement 12 noch drei weitere Innengewinde 18,20,24, die nebeneinanderliegend im Basiselement 12 vorgesehen sind. Der Stift 14 kann wahlweise in jedes Innengewinde 16,18,20,24 im Basiselement 12 eingeschraubt werden, um verschiedene Befestigungsmöglichkeiten zu bieten und den Sitz des Schnellspannverschlusses 10 an die Größe der Lasche anzupassen, insbesondere an den Abstand der Schnüröse, in welche der Stift 14 eingesetzt ist, von einer freien Außenkante der Lasche.Except for the internal thread 16, in which in the illustration in Fig. 1 When the pin 14 is screwed in, the base element 12 also comprises three further internal threads 18, 20, 24, which are provided in the base element 12 next to one another. The pin 14 can optionally be screwed into each internal thread 16,18,20,24 in the base element 12 in order to offer various fastening options and to adapt the seat of the quick release fastener 10 to the size of the tab, in particular to the distance between the Lace-up eyelets into which the pin 14 is inserted from a free outer edge of the flap.

Der Stift 14 weist an seinem freien, dem einzuschraubenden Ende abgewandten Ende einen Kopf 36 auf, der die Handhabung und das Drehen des Stiftes 14 mit den Fingern eines Benutzers erleichtert. Dieser Kopf 36 liegt in der angebrachten Stellung des Schnellspannverschlusses 10 unterhalb der Lasche, wie im folgenden noch näher erläutert werden soll.At its free end facing away from the end to be screwed in, the pin 14 has a head 36 which facilitates the handling and turning of the pin 14 with the fingers of a user. This head 36 is in the attached position of the quick release fastener 10 below the tab, as will be explained in more detail below.

Der Schnellspannverschluss 10 umfasst ferner ein Spannelement 26, das mit dem Basiselement 12 um eine Schwenkachse 28 schwenkbar verbunden ist. Die Schwenkachse 28 erstreckt sich senkrecht zur Achse des Stifts 14. Im angebrachten Zustand an der Lasche liegt die Schwenkachse 28 seitlich neben einer freien Außenkante der Lasche.The quick release fastener 10 further comprises a tensioning element 26, which is connected to the base element 12 so as to be pivotable about a pivot axis 28. The pivot axis 28 extends perpendicular to the axis of the pin 14. In the attached state on the bracket, the pivot axis 28 lies laterally next to a free outer edge of the bracket.

Von der Schwenkachse 28 aus erstreckt sich ein Grundkörper 30 des Spannelements 26, der an einer Seite mit einer Ausnehmung 32 versehen ist. Diese dient zur Aufnahme des Basiselements 12, wenn das Spannelement 26 auf das Basiselement 12 geklappt wird. Dieses kann dann zumindest mit seinem oberen Bereich in der Ausnehmung 32 aufgenommen werden. Das Spannelement 26 weist eine größere Breite auf als das Basiselement 12, so dass das Basiselement 12 im geschlossenen Zustand des Schnellspannverschlusses 10 vollständig vom Spannelement 26 abgedeckt wird, wie es in Fig. 2 gezeigt ist.A base body 30 of the tensioning element 26, which is provided with a recess 32 on one side, extends from the pivot axis 28. This serves to accommodate the base element 12 when the tensioning element 26 is folded onto the base element 12. This can then be received in the recess 32 at least with its upper area. The tensioning element 26 has a greater width than the base element 12, so that the base element 12 is completely covered by the tensioning element 26 in the closed state of the quick release fastener 10, as shown in FIG Fig. 2 is shown.

Das Spannelement 26 umfasst eine Öse 34, die sich im Abstand von der Schwenkachse 28 am freien Ende des Spannelements 26 parallel zur Schwenkachse 28 durch den Grundkörper 30 des Spannelements 26 erstreckt. Ein Schnürsenkel kann durch diese Öse 34 gefädelt werden. Die Öse 34 wird durch einen zu gegenüberliegenden Seiten des Grundkörpers 30 offenen Kanal gebildet, der einen Teil des Grundkörpers 30 zwischen dem Ende der Ausnehmung 32 und dem freien Ende des Grundkörpers 30 durchläuft.The tensioning element 26 comprises an eyelet 34 which extends at a distance from the pivot axis 28 at the free end of the tensioning element 26 parallel to the pivot axis 28 through the base body 30 of the tensioning element 26. A shoelace can be threaded through this eyelet 34. The eyelet 34 is formed by a channel which is open on opposite sides of the base body 30 and which runs through part of the base body 30 between the end of the recess 32 and the free end of the base body 30.

Fig. 3 zeigt den Schnellspannverschluss 10 in der geschlossenen Stellung (entsprechend Fig. 2) von unten. In den Seitenansichten in den Fig. 4 und 5, die jeweils wiederum die geöffnete und die geschlossene Stellung des Schnellspannverschlusses 10 darstellen, ist sichtbar, dass das Basiselement 12 einen im wesentlichen U-förmigen Körper 38 zum seitlichen Aufschieben auf die Lasche umfasst. Ein oberer, auf der Lasche aufliegender Schenkel 40 ist mit den in Fig. 1 sichtbaren Innengewinden 16,18,20,24 zum Einschrauben eines Einschraubendes des Stifts 14 versehen. Der andere Schenkel 44 weist ein Langloch 46 (Fig. 3) auf, durch welches der Stift 14 gesteckt werden kann. Die Schwenkachse 28 ist an dem Ende des Basiselements 12 angebracht, an welchem die Schenkel 40,44 zusammenlaufen. Dieses Ende bildet einen Anschlag beim Aufstecken des Basiselements 12 auf die Lasche, wie im folgenden noch gezeigt werden soll. Der Stift 14 durchquert an dem gegenüberliegenden freien Ende der Schenkel 40,44 den Zwischenraum zwischen diesen. Fig. 3 shows the quick release fastener 10 in the closed position (corresponding to Fig. 2 ) from underneath. In the side views in the Figures 4 and 5 which in turn represent the open and closed positions of the quick release fastener 10, it can be seen that the base element 12 comprises an essentially U-shaped body 38 for laterally sliding onto the tab. An upper leg 40 resting on the tab is connected to the in Fig. 1 visible internal threads 16,18,20,24 for screwing in a screw-in end of the pin 14 is provided. The other leg 44 has an elongated hole 46 ( Fig. 3 ) through which the pin 14 can be inserted. The pivot axis 28 is attached to the end of the base element 12 at which the legs 40, 44 converge. This end forms a stop when the base element 12 is slipped onto the tab, as will be shown below. At the opposite free end of the legs 40, 44, the pin 14 traverses the space between them.

Deutlich ist in den Fig. 4 und 5 erkennbar, dass die Öse 34 im Spannelement 26 in der offenen Stellung weiter vom Stift 14 entfernt ist als in der geschlossenen Stellung. Beim Schließen des Spannelements 26 wird somit der Abschnitt eines durch die Öse 34 geführten Schnürsenkels bogenförmig in Richtung des Stiftes 14 geschwenkt. Die Schenkel 40,44 und das Spannelement 26 weisen eine Krümmung auf, die etwa der Krümmung der am Fuß anliegenden Lasche folgen soll und einen bequemen Sitz des Schnellspannverschlusses 10 fördert.It is clear in the Figures 4 and 5 It can be seen that the eyelet 34 in the tensioning element 26 is further away from the pin 14 in the open position than in the closed position. When the tensioning element 26 is closed, the section of a shoelace guided through the eyelet 34 is pivoted in an arc-shaped manner in the direction of the pin 14. The legs 40, 44 and the tensioning element 26 have a curvature which is intended to approximately follow the curvature of the tab resting on the foot and which promotes a comfortable fit of the quick release fastener 10.

In der geschlossenen Stellung wird das Spannelement 26 durch geeignete Verriegelungsmittel auf dem Basiselement 12 gehalten, um ein versehentliches Lösen und Öffnen des Schnellspannverschlusses 10 zu verhindern. Bei der vorliegenden Ausführungsform umfassen diese Verriegelungsmittel Rastmittel, die es erlauben, das Spannelement 26 beim Schließen auf dem Basiselement 12 zu verrasten. Diese Verrastung kann durch Anheben des freien Endes des Spannelements 26 gelöst werden.In the closed position, the clamping element 26 is held on the base element 12 by suitable locking means in order to prevent accidental loosening and opening of the quick release fastener 10. In the present embodiment, these locking means comprise latching means which allow the tensioning element 26 to be latched onto the base element 12 when it is closed. This latching can be released by lifting the free end of the tensioning element 26.

Die Verrastung wird bei der vorliegenden Ausführungsform durch eine Verdickung 48 an der Oberseite des oberen Schenkels 40 des Basiselements 12 gebildet, so dass dieser Schenkel 40 einen Querschnitt aufweist, der einem Schwalbenschwanz ähnelt. Diese Verdickung 48 wird in die Öffnung der Ausnehmung 32 im Spannelement 26 eingeclipst. Dies wird dadurch gewährleistet, dass die Öffnung der Ausnehmung 32 zum Basiselement 12 hin einen geringfügig kleineren Querschnitt aufweist als die maximale Breite der Verdickung 48, so dass beim Schließen des Schnellspannverschlusses 10 die Öffnung der Ausnehmung 32 geringfügig aufgespreizt werden muss. Dies geschieht gegen einen elastischen Widerstand des Materials des Spannelements 26. Erreicht der obere Schenkel 40 des Basiselements 12 seinen endgültigen Sitz in der Ausnehmung 32, gleiten die seitlichen Wände 50,52, welche die Ausnehmung 32 im Spannelement 26 begrenzen, wieder in ihre ursprüngliche Position zurück, so dass Spannelement 26 und Basiselement 12 ihre geschlossene Stellung beibehalten.In the present embodiment, the latching is formed by a thickening 48 on the upper side of the upper leg 40 of the base element 12, so that this leg 40 has a cross section that resembles a dovetail. This thickening 48 is clipped into the opening of the recess 32 in the tensioning element 26. This is ensured by the fact that the opening of the recess 32 towards the base element 12 has a slightly smaller cross-section than the maximum width of the thickening 48, so that when the quick release fastener 10 is closed, the opening of the recess 32 has to be spread open slightly. This takes place against an elastic resistance of the material of the tensioning element 26. When the upper leg 40 of the base element 12 reaches its final seat in the recess 32, the side walls 50, 52, which delimit the recess 32 in the tensioning element 26, slide back into their original position back so that clamping element 26 and base element 12 maintain their closed position.

Die Verdickung 48 muss sich nicht über die gesamte Länge des Basiselements 12 zwischen der Schwenkachse 28 und dem gegenüberliegenden freien Ende des Basiselements 12 erstrecken, sondern die Verdickung 48 kann auch lediglich an einem Punkt dieser Länge vorhanden sein. Zudem sind auch andere Rastmechanismen denkbar, wie etwa eine vergleichbare Verrastung an den Enden der Ausnehmung 32 bzw. des Basiselements 12.The thickening 48 does not have to extend over the entire length of the base element 12 between the pivot axis 28 and the opposite free end of the base element 12, but the thickening 48 can also only be present at one point of this length. In addition, other latching mechanisms are also conceivable, such as a comparable latching at the ends of the recess 32 or of the base element 12.

Fig. 7 zeigt den Schnellspannverschluss 10 in einer Anwendung an einem Schnürschuh. Dieser umfasst eine erste Lasche 100 (in Fig. 7 links) und eine gegenüberliegende zweite Lasche 102. Jede dieser Laschen 100,102 umfasst drei Schnürösen. Auf die erste Lasche 100 ist das (hier verdeckte) Basiselement 12 von der freien, zu der zweiten Lasche 102 weisenden Kante 104 her aufgesteckt, derart, dass die Lasche 100 vollständig in den schlitzförmigen Zwischenraum zwischen den Schenkeln 40,44 (Fig. 4 und 5) eingeschoben ist. In der mittleren, nicht sichtbaren Schnüröse der ersten Lasche 100 ist der Stift 14 des Schnellspannverschlusses 10 eingesetzt, so dass der Schnellspannverschluss 10 an dieser ersten Lasche 100 gehalten wird, und zwar derart, dass die Schwenkachse 28 entlang der Kante 104 der ersten Lasche 100 angeordnet ist und parallel zu dieser verläuft. Hierdurch ist der Schnellspannverschluss 10 verdrehsicher an der Lasche 100 angebracht. In der geschlossenen Stellung, die in Fig. 7 dargestellt ist, liegt das Spannelement 26 auf der Oberseite der ersten Lasche 100 auf und verdeckt das Basiselement 12. Die übrigen Ösen 106,108 der ersten Lasche 100 bleiben zum Durchfädeln eines Schnürsenkels 110 frei. Fig. 7 shows the quick release fastener 10 in an application on a lace-up shoe. This comprises a first tab 100 (in Fig. 7 left) and an opposite second tab 102. Each of these tabs 100, 102 comprises three lacing loops. The base element 12 (which is covered here) is slipped onto the first tab 100 from the free edge 104 facing the second tab 102, in such a way that the tab 100 completely enters the slot-shaped space between the legs 40, 44 ( Figures 4 and 5 ) is inserted. The pin 14 of the quick release fastener 10 is inserted in the middle, invisible lacing loop of the first flap 100, so that the quick release fastener 10 is held on this first bracket 100, in such a way that the pivot axis 28 is arranged along the edge 104 of the first bracket 100 and runs parallel to it. As a result, the quick release fastener 10 is attached to the bracket 100 in a manner secure against rotation. In the closed position, which is in Fig. 7 is shown, the tensioning element 26 rests on the upper side of the first flap 100 and covers the base element 12. The remaining eyelets 106, 108 of the first flap 100 remain free for threading a shoelace 110.

Bei der Schnürung wird der Schnürsenkel 110 durch die am Schuh gegenüberliegenden Ösen durchgefädelt. Unter den Laschen 100,102 verlaufende Abschnitte des Schnürsenkels 110 sind durch gestrichelte Linien dargestellt. Der Schnürsenkel 110 wird zunächst mit einem mittleren Abschnitt quer zwischen beiden Laschen 100 und 102 gespannt und jeweils in deren unterste Ösen 108 und 112 eingefädelt, dann mit einem Ende unter der ersten Lasche 100 nach oben zur obersten Öse 106 derselben und dort wieder heraus, und mit dem anderen Ende unter der zweiten Lasche 102 von der untersten Öse 112 nach oben bis zur mittleren Öse 114 derselben und aus dieser heraus, und quer hinüber auf die Oberseite der ersten Lasche 100 und dort nach oben durch den Kanal der Öse 34 des Schnellspannverschlusses 10. Der aus dieser Öse 34 austretende Abschnitt des Schnürsenkels 110 wird wiederum zur oberen Schnüröse 116 der zweiten Lasche 102 gezogen und dort von deren Unterseite her durchgefädelt. Die Öse 34 des Schnellspannverschlusses 10 ersetzt somit die mittlere Öse der ersten Lasche 100. Wird der Schnellspannverschluss 10 durch Anheben des Spannelements 26 gelöst, wird auch die Spannung zwischen den Ösen 112,114,116 der zweiten Lasche 102 und der Öse 34 des Schnellspannverschlusses 10 gelöst und gelockert.When lacing, the shoelace 110 is threaded through the eyelets on the opposite side of the shoe. Sections of the shoelace 110 running under the tabs 100, 102 are shown by dashed lines. The shoelace 110 is first stretched with a middle section transversely between the two flaps 100 and 102 and threaded into their lowest eyelets 108 and 112, then with one end under the first flap 100 up to the uppermost eyelet 106 of the same and out again, and with the other end under the second tab 102 from the lowest eyelet 112 upwards to the middle eyelet 114 of the same and out of this, and across over to the top of the first tab 100 and there up through the channel of the eyelet 34 of the quick release fastener 10 The section of the shoelace 110 emerging from this eyelet 34 is in turn pulled to the upper eyelet 116 of the second flap 102 and threaded through there from the underside thereof. The eyelet 34 of the quick release fastener 10 thus replaces the middle eyelet of the first flap 100. If the quick release fastener 10 is released by lifting the clamping element 26, the tension between the eyelets 112, 114, 116 of the second flap 102 and the eyelet 34 of the quick release fastener 10 is also released and loosened.

Dies wird nochmals in den Fig. 8 und 9 verdeutlicht. In der offenen Stellung in Fig. 8, in welcher das Spannelement 26 aufgeklappt ist, ist der durch die Öse 34 gefädelte Abschnitt des Schnürsenkels 110 gelockert. Wird das Spannelement 26 in die geschlossene Stellung gebracht, also durch Schwenken um die Schwenkachse 28, vollführt die Öse 34 eine bogenförmige Schwenkbewegung, so dass ihr Abstand von den Ösen 112,114,116 vergrößert wird und der betreffende Abschnitt des Schnürsenkels 110 gespannt wird, wie es in Fig. 9 dargestellt ist.This is repeated in the Figures 8 and 9 made clear. In the open position in Fig. 8 , in which the tensioning element 26 is unfolded, the section of the shoelace 110 threaded through the eyelet 34 is loosened. If the clamping element 26 is brought into the closed position, that is to say by pivoting about the pivot axis 28, the eyelet is carried out 34 an arcuate pivoting movement, so that their distance from the eyelets 112, 114, 116 is increased and the relevant section of the shoelace 110 is tensioned, as shown in FIG Fig. 9 is shown.

Die Zahl der Schnürösen in den Laschen 100,102 ist in Fig. 7 lediglich beispielhaft dargestellt. Ferner ist es auch möglich, das Spannelement 26 anders auszubilden als hier dargestellt, so dass es beispielsweise auch mehrere Ösen 34 umfassen kann, die senkrecht zur ersten Lasche 100, also sich parallel zur Achse des Stifts 14 durch das Spannelement 26 erstrecken. Ferner sind sämtliche Elemente des erfindungsgemäßen Schnellspannverschlusses 10 hier lediglich beispielhaft und schematisch dargestellt, so dass ihre Proportionen von den Darstellungen in den Figuren abweichen können.The number of eyelets in the tabs 100,102 is in Fig. 7 shown only as an example. Furthermore, it is also possible to design the tensioning element 26 differently than shown here, so that, for example, it can also include several eyelets 34 that extend perpendicular to the first tab 100, i.e. parallel to the axis of the pin 14 through the tensioning element 26. Furthermore, all elements of the quick release fastener 10 according to the invention are shown here only by way of example and schematically, so that their proportions can deviate from the representations in the figures.
