Description

Die vorliegende Erfindung betrifft eine Klemmvorrichtung zur lösbaren Fixierung von Schnürsenkeln.The present invention relates to a clamping device for releasably fixing laces.

Bei Stiefeln für spezielle Arbeitseinsätze, insbesondere Feuerwehrstiefeln, haben sich Hilfsmittel zur Fixierung der Schnürsenkel als vorteilhaft erwiesen. Diese Hilfsmittel, wie beispielsweise am Stiefel befestigte Klemmen und andere mechanische Verschlüsse, stellen gegenüber von Hand gebundenen Schleifen und Knoten eine gute Alternative dar, um die Schnürung über dem Fuß gestrafft zu halten, da sie ein rascheres Fixieren der Schnürsenkel ermöglichen und mit ihnen ein unerwünschtes Lösen der Schnürsenkel besser verhindert werden kann.In boots for special work, especially firefighters, aids for fixing the laces have proven to be advantageous. These aids, such as boot-mounted clamps and other mechanical fasteners, provide a good alternative to hand-tied loops and knots to keep the laces taut above the foot as they allow for faster fixation of the laces and undesirable loosening of the laces Loosen the laces better can be prevented.

Als ein Mittel zur Fixierung einer Schnürung an einem Stiefel ist eine an der Zunge befestigte Klemme bekannt, an der die Schnürsenkel durch Schließen eines mechanischen Hebels fixiert werden. Bei Verwendung dieser Klemme werden beim Fixieren die Schnürsenkel zunächst mit der einen Hand ergriffen und bis zum Erreichen der gewünschten Straffung der Schnürung angezogen. Dann wird unter Aufrechterhaltung der Zugkraft an den Schnürsenkeln mit der anderen Hand der Hebel an der Klemme umgelegt, wodurch die Schürsenkel fixiert werden. Die bekannte Klemme gewährleistet einen sicheren Halt der am Stiefel gestrafften Schnürsenkel. Nachteilig dabei ist jedoch, dass zur Straffung und Fixierung der Schnürung beide Hände eingesetzt werden müssen.As a means for fixing a lacing on a boot, there is known a clip fixed to the tongue to which the laces are fixed by closing a mechanical lever. When using this clamp, the laces are first grasped with one hand while fixing and tightened until the desired tightening of the lacing. Then, while maintaining the tension on the shoelaces with the other hand, the lever is folded over at the clamp, whereby the shoelaces are fixed. The well-known clamp ensures a secure hold of the laces tightened on the boot. The disadvantage here is that both hands must be used to streamline and fix the lacing.

US Pat. No. 6,178,606 B discloses an apparatus for securing shoelaces to an outer cylinder and a cylindrical inner member, wherein openings in the outer cylinder and inner member are aligned with each other and a lace may be threaded through the openings in the outer cylinder and inner member.

DE 11 2006 001 579 T5 offenbart eine Schnürsenkelverriegelung mit einem Gehäuse, welches angepasst ist, einen Schnürsenkel durch dieses hindurch aufzunehmen, wobei das Gehäuse eine Vorderwand und eine Rückwand aufweist, einem Nockenhebel, der drehbar an der Rückwand angebracht ist, wobei der Nockenhebel zwischen einer Verriegelungsposition, in welcher der aufgenommene Schnürsenkel kraftschlüssig zwischen dem Nockenbereich und der Gehäusevorderwand gehalten wird und einer Freigabeposition bewegbar ist, in welcher der aufgenommene Schnürsenkel nicht durch den Nockenbereich gehalten wird. DE 11 2006 001 579 T5 discloses a lace lock having a housing adapted to receive a lace therethrough, the housing having a front wall and a rear wall, a cam lever rotatably mounted on the rear wall, the cam lever between a locking position in which the received Shoe is frictionally held between the cam portion and the housing front wall and a release position is movable, in which the recorded shoe lace is not held by the cam portion.

Es ist die Aufgabe der vorliegenden Erfindung eine Klemmvorrichtung für Schnürsenkel bereitzustellen, mit der die gestrafften Schnürsenkel einfacher und lediglich mit einer Hand fixiert werden können.It is the object of the present invention to provide a lacing device for laces, with which the tightened laces can be fixed more easily and only with one hand.

Diese Aufgabe wird gelöst durch eine Klemmvorrichtung mit den Merkmalen des Hauptanspruchs 1.This object is achieved by a clamping device with the features of the main claim. 1

Erfindungsgemäß wird eine Klemmvorrichtung zur lösbaren Fixierung von Schnürsenkeln bereitgestellt, die ein Gehäuse mit vier das Gehäuse durchquerenden Kanälen zur Aufnahme jeweils eines Schnürsenkels umfasst, wobei jedem Kanal eine in Richtung des Kanals verschiebbarer Klemmbolzen zugeordnet ist und die Kanäle so ausgebildet sind, dass ihr Querschnitt in Abhängigkeit von der Position der Klemmbolzen verringert werden kann, um die in den Kanälen angeordneten Schnürsenkel festzuklemmen.According to the invention, a clamping device for releasably fixing shoelaces is provided which comprises a housing with four channels passing through the housing for receiving a respective shoelace, wherein each channel is assigned a displaceable in the direction of the channel clamping bolt and the channels are formed so that their cross-section Depending on the position of the clamping bolt can be reduced to clamp the laces arranged in the channels.

Mit der erfindungsgemäßen, vorzugsweise zur Befestigung an einem Stiefel eingerichteten Klemmvorrichtung kann eine sichere Fixierung von Schnürsenkeln erreicht werden, da die Klemmbolzen durch die Zugkräfte, die durch die gestraffte Schnürung auf die Schnürsenkel ausgeübt und durch Reibung auf die Klemmbolzen übertragen werden, in den Bereich der Kanäle mit verringertem Querschnitt mitgenommen werden, wo die Schnürsenkel zwischen den Klemmbolzen und den Wänden des Gehäuses der Klemmvorrichtung festgeklemmt werden. Da der Querschnitt der Kanäle in der Zugrichtung abnimmt, erhöht sich die Klemmwirkung mit zunehmenden Zugkräften und je weiter die Klemmbolzen in die Verriegelungsrichtung der Klemme gezogen werden.With the invention, preferably for attachment to a boot equipped clamping device secure fixation of shoelaces can be achieved because the clamping bolts by the tensile forces exerted by the tightened lacing on the laces and friction transferred to the clamping bolt in the field of Chases are taken with reduced cross-section, where the laces between the clamping bolt and the walls of the housing of the clamping device are clamped. As the cross-section of the channels in the pulling direction decreases, the clamping action increases with increasing tensile forces and the farther the clamping bolts are pulled in the locking direction of the clamp.

Darüber hinaus können die Schnürsenkel mit einer einzigen Hand gestrafft und fixiert werden, da die Klemmbolzen beim Straffen der Schnürung durch Ziehen an den Schnürsenkeln entgegen der Verriegelungsrichtung durch die Reibung in den Bereich der Kanäle mit vergrößertem Querschnitt mitgenommen werden, wo keine Klemmkräfte auf die Schnürsenkel wirken und diese im wesentlichen widerstandsfrei beweglich sind. Sobald die gewünschte Straffung der Schnürung erreicht ist, werden die Schnürsenkel losgelassen und die Klemmbolzen durch die Zugkräfte der gespannten Schnürung in Verriegelungsrichtung mitgenommen, sodass die Schnürsenkel festgeklemmt werden. Dieser Vorgang kann ohne den Einsatz der zweiten Hand ausgeführt werden. Insgesamt weist die erfindungsgemäße Klemmvorrichtung eine sehr kompakte Form und Bauweise auf.In addition, the laces can be tightened and fixed with a single hand, since the clamping bolts are taken by tightening the laces by pulling the laces against the locking direction by the friction in the region of the channels with increased cross section, where no clamping forces acting on the laces and these are substantially resistant to movement. As soon as the desired tightening of the lacing has been achieved, the laces are released and the clamping bolts are pulled along in the locking direction by the tensile forces of the taut lacing so that the laces are clamped tight. This process can be performed without the use of the second hand. Overall, the clamping device according to the invention has a very compact shape and design.

Gemäß einer bevorzugten Ausführungsform sind die Klemmbolzen miteinander verbunden und gemeinsam verschiebbar.According to a preferred embodiment, the clamping bolts are connected together and displaceable together.

Gemäß einer weiteren Ausführungsform weisen die miteinander verbundenen Klemmbolzen einen von der Außenseite des Gehäuses betätigbaren Hebel auf, durch den die miteinander verbundenen Klemmbolzen verschoben werden können. Der Hebel kann auch als Drücker ausgebildet sein, durch dessen Betätigung von der Außenseite des Gehäuses die Klemmbolzen entgegen der Verriegelungsrichtung bewegt werden können, sodass die Schnürsenkel freigegeben und gelöst werden.According to a further embodiment, the interconnected clamping bolts on an operable from the outside of the housing lever through which the interconnected clamping bolts can be moved. The lever can also be used as a pusher be formed, by the actuation of the outside of the housing, the clamping bolt can be moved against the locking direction, so that the laces are released and released.

Gemäß einer anderen bevorzugten Ausführungsform verjüngen sich die Querschnitte der Kanäle zwischen den Klemmbolzen und den gegenüberliegenden Wänden der Kanäle in einer Richtung senkrecht zur Verbindungsrichtung zwischen den Kanälen. Die Kanäle und die ihnen zugeordneten Klemmbolzen können jeweils nebeneinander angeordnet sein, wobei sich die Kanäle in derselben Richtung verjüngen.According to another preferred embodiment, the cross-sections of the channels between the clamping bolts and the opposite walls of the channels taper in a direction perpendicular to the direction of connection between the channels. The channels and their associated clamping bolts can each be arranged next to each other, with the channels tapering in the same direction.

Gemäß einer noch weiteren Ausführungsform sind die Klemmbolzen so ausgebildet, dass sie beim Verschieben an einer oder mehreren Wänden des Gehäuses, in den Kanälen oder auch an einer oder mehreren Wänden des Gehäuses und in den Kanälen geführt werden. Insbesondere können die Klemmbolzen zwischen zwei einen Kanal definierenden Wänden geführt sein.According to yet another embodiment, the clamping bolts are designed so that they are guided when moving on one or more walls of the housing, in the channels or even on one or more walls of the housing and in the channels. In particular, the clamping bolts can be guided between two walls defining a channel.

Gemäß noch einer Ausführungsform sind im Gehäuse auf einer Seite einer Querschnittsebene der Klemmvorrichtung die Klemmbolzen und auf der gegenüberliegenden Seite die zur Aufnahme der Schnürsenkel vorgesehenen Bereiche der Kanäle angeordnet und die Schnürsenkel zwischen den Klemmbolzen und den zu den Klemmbolzen gegenüberliegenden Wänden der Kanäle festklemmbar. Die Kanäle mit den ihnen zugeordneten Klemmbolzen können gemäß dieser Ausführungsform nebeneinander angeordnet werden.According to another embodiment, the clamping bolts are arranged in the housing on one side of a cross-sectional plane of the clamping device and on the opposite side of the regions provided for receiving the laces and the laces between the clamping bolt and the walls of the channels opposite to the clamping bolt clamped. The channels with their associated clamping bolts can be arranged side by side according to this embodiment.

Gemäß noch einer weiteren Ausführungsform erstrecken sich die Kanäle parallel und geradlinig durch das Gehäuse.According to yet another embodiment, the channels extend parallel and rectilinearly through the housing.

Gemäß einer anderen Ausführungsform weist die Klemmvorrichtung vier nebeneinander angeordnete Kanäle zur Aufnahme von vier Schnürsenkeln und vier an den Kanälen entsprechend angeordnete Klemmbolzen auf. Diese Ausführungsform der Klemmvorrichtung eignet sich insbesondere für Stiefel mit zwei unabhängigen Schnürungen. Mit Hilfe dieser Ausführungsform der Klemmvorrichtung können vier Schnürsenkel gleichzeitig mit einer Hand gestrafft und festgeklemmt werden.According to another embodiment, the clamping device has four adjacent channels for receiving four shoelaces and four correspondingly arranged on the channels clamping bolt. This embodiment of the clamping device is particularly suitable for boots with two independent lacing. With the help of this embodiment of the clamping device four laces can be tightened and clamped simultaneously with one hand.

Gemäß noch einer anderen Ausführungsform sind alle vier Klemmbolzen miteinander verbunden. Alternativ können jedoch auch jeweils zwei Klemmbolzen miteinander verbunden sein. Beispielsweise können die beiden innen liegend im Gehäuse angeordneten Klemmbolzen und die beiden außen im Gehäuse angeordneten Klemmbolzen miteinander verbunden werden, sodass jede der Schnürungen mit jeweils zwei Schnürsenkeln unabhängig von der anderen Schnürung fixiert und gelöst werden kann. Die Klemmbolzen und die vier Kanäle sind jeweils nebeneinander in einer Reihe angeordnet.According to yet another embodiment, all four clamping bolts are connected together. Alternatively, however, two clamping bolts can also be connected to each other. For example, the two clamping bolts arranged inside the housing and the two clamping bolts arranged outside in the housing can be connected to each other, so that each of the laces can be fixed and released with two laces each independently of the other lacing. The clamping bolts and the four channels are each arranged side by side in a row.

Erfindungsgemäß wird darüber hinaus ein Stiefel mit einer Klemmvorrichtung der zuvor beschriebenen Art erfindungsgemäß bereitgestellt, wobei die Klemmvorrichtung an der Zunge des Stiefels befestigt ist. Der erfindungsgemäße Stiefel kann mit Hilfe der Klemmvorrichtung rasch und unter Zuhilfenahme lediglich einer Hand geschlossen werden, wobei die Schnürsenkel zuverlässig fixiert sind und ein unerwünschtes Lösen verhindert werden kann.According to the invention a boot with a clamping device of the type described above is also provided according to the invention, wherein the clamping device is attached to the tongue of the boot. The boot according to the invention can be closed quickly and with the aid of the clamping device with the aid of only one hand, the laces are reliably fixed and unwanted loosening can be prevented.

Gemäß einer bevorzugten Ausführungsform umfasst der Stiefel zwei Schnürungen, wobei die erste Schnürung an einem dem Vorderfuß entsprechenden vorderen Stiefelabschnitt und die zweite Schnürung am Schaft angeordnet ist.According to a preferred embodiment, the boot comprises two laces, wherein the first lacing is arranged on a front boot section corresponding to the front foot and the second lacing on the shaft.

Gemäß einer weiteren bevorzugten Ausführungsform sind die vier Schnürsenkel der beiden Schnürungen mit einer gemeinsamen Zugeinrichtung verbunden. Mit Hilfe der Zugeinrichtung können alle vier Schnürsenkel gleichzeitig straff gezogen und beide Schnürungen gleichzeitig gespannt werden. Dadurch wird ein sehr rasches Schließen des Stiefels möglich.According to a further preferred embodiment, the four laces of the two laces are connected to a common pulling device. With the help of the drawbar, all four laces can be pulled taut at the same time and both laces can be tensioned simultaneously. This makes a very fast closing of the boot possible.

Eine Ausführungsform der erfindungsgemäßen Klemmvorrichtung wird im Folgenden anhand der Fig. 1 bis Fig. 5 beschrieben. Die Klemmvorrichtung gemäß der gezeigten Ausführungsform umfasst ein im Wesentlichen quaderförmiges Gehäuse 1 mit einer Vorderwand 3, einer Rückwand 5 und Seitenwänden 7, die sich jeweils zwischen der Vorder- und Rückwand 3, 5 erstrecken. An der Unterseite umfasst das Gehäuse 1 eine Bodenplatte 9 und an der Oberseite ist das Gehäuse 1 mit einem abnehmbaren Deckel 11 verschlossen, der durch eine Bohrung 13 mit einer Schraube (nicht gezeigt) mit dem Gehäuse 1 fest verbunden werden kann. In der Bodenplatte 9 und im Deckel 11 sind jeweils vier Durchgangsöffnungen 15, 16, 17, 18, 19, 20, 21, 22 ausgebildet, die sich entsprechend gegenüberliegen. Zwischen den Durchgangsöffnungen 15, 17, 19, 21 im Deckel 11 und den Durchgangsöffnungen 16, 18, 20, 22 in der Bodenplatte 9 sind an der Rückwand 5 jeweils Kanäle 23, 25, 27, 29 ausgebildet, die sich geradlinig und parallel zwischen den Durchgangsöffnungen 15, 16, 17, 18, 19, 20, 21, 22 in der Bodenplatte 9 und im Deckel 11 erstrecken. Im Gehäuse 1 erstrecken sich von der Rückwand 5 vorzugsweise senkrechte Wände 31, 32, 33, 34, 35, 37, zwischen welchen die Kanäle 23, 25, 27, 29 definiert sind. Im Gehäuse 1 sind den Kanälen 23, 25, 27, 29 jeweils zugeordnete Klemmbolzen 39, 41, 43, 45 angeordnet, die miteinander durch einen sich quer zu den Klemmbolzen 39, 41, 43, 45 erstreckenden Steg 47 miteinander verbunden sind. Senkrecht vom Steg 47 erstreckt sich ein Drücker 49, der durch eine entsprechende Öffnung 51 in der Bodenplatte 9 des Gehäuses 1 geführt ist. Der Drücker 49 weist im Querschnitt eine T-Form auf und ist mittig am Steg 47 zwischen den beiden inneren Klemmbolzen 41, 43 ausgebildet. Die Öffnung 51 in der Bodenplatte 9 weist ebenfalls eine T-Form auf. Die vier Klemmbolzen 39, 41, 43, 45 bilden zusammen mit dem Steg 47 und dem Drücker 49 eine einstückige Klemmbolzenvorrichtung 53, die beweglich im Gehäuse 1 angeordnet ist und parallel zur Vorderwand 3 und Rückwand 5 zwischen der Bodenplatte 9 und dem Deckel 11 verschoben werden kann. Die Länge des Steges 47 und der gesamten Klemmbolzenvorrichtung 53 ist so gewählt, dass sie der inneren Breite des Gehäuses 1 entspricht, sodass die beiden Seitenwände 7 des Gehäuses 1 als Führung für die Klemmbolzenvorrichtung 53 dienen können. Zusätzlich können die Klemmbolzen 39, 41, 43, 45 der Klemmbolzenvorrichtung 53 an den die Kanäle 23, 25, 27, 29 trennenden Wänden 31, 33, 35, 37 geführt sein. Die Klemmbolzenvorrichtung 53 befindet sich im Gehäuse an der Innenseite der Vorderwand 3. Wie in den Figuren dargestellt ist, sind in den Kanälen 23, 25, 27, 29 Schnürsenkel 24, 26, 28, 30 angeordnet, die zwischen der Rückwand 5 und den Klemmbolzen 39, 41, 43, 45 verlaufen.An embodiment of the clamping device according to the invention is described below with reference to the Fig. 1 to Fig. 5 described. The clamping device according to the embodiment shown comprises a substantially cuboid housing 1 with a front wall 3, a rear wall 5 and side walls 7, each extending between the front and rear walls 3, 5 extend. At the bottom, the housing 1 comprises a bottom plate 9 and at the top the housing 1 is closed with a removable cover 11 which can be fixedly connected to the housing 1 by a bore 13 with a screw (not shown). In the bottom plate 9 and the lid 11, four through holes 15, 16, 17, 18, 19, 20, 21, 22 are respectively formed, which are correspondingly opposite. Between the passage openings 15, 17, 19, 21 in the cover 11 and the passage openings 16, 18, 20, 22 in the bottom plate 9 channels 23, 25, 27, 29 are respectively formed on the rear wall 5, which are rectilinear and parallel between the Through openings 15, 16, 17, 18, 19, 20, 21, 22 extend in the bottom plate 9 and in the lid 11. In the housing 1 extend from the rear wall 5 preferably vertical walls 31, 32, 33, 34, 35, 37, between which the channels 23, 25, 27, 29 are defined. In the housing 1, the channels 23, 25, 27, 29 respectively associated clamping bolt 39, 41, 43, 45 are arranged, which are interconnected by a transverse to the clamping bolt 39, 41, 43, 45 extending web 47 together. Perpendicular to the web 47 extends a pusher 49 which is guided through a corresponding opening 51 in the bottom plate 9 of the housing 1. The pusher 49 has a T-shape in cross-section and is formed centrally on the web 47 between the two inner clamping bolts 41, 43. The opening 51 in the bottom plate 9 also has a T-shape. The four clamping bolts 39, 41, 43, 45, together with the web 47 and the pusher 49, a one-piece clamping bolt device 53 which is movably disposed in the housing 1 and parallel to Front wall 3 and rear wall 5 between the bottom plate 9 and the lid 11 can be moved. The length of the web 47 and the entire clamping bolt device 53 is selected so that it corresponds to the inner width of the housing 1, so that the two side walls 7 of the housing 1 can serve as a guide for the clamping bolt device 53. In addition, the clamping bolts 39, 41, 43, 45 of the clamping bolt device 53 on the channels 23, 25, 27, 29 separating walls 31, 33, 35, 37 may be performed. The clamping bolt device 53 is located in the housing on the inside of the front wall 3. As shown in the figures, in the channels 23, 25, 27, 29 shoelaces 24, 26, 28, 30 are arranged between the rear wall 5 and the clamping bolt 39, 41, 43, 45.

Die beiden Endpositionen, zwischen welchen die Klemmbolzenvorrichtung 53 im Gehäuse 1 verschoben werden kann, sind in den Fig. 3a und 3b bzw. 4a und 4b dargestellt. Wie in Fig. 3a und Fig. 3b zu erkennen ist, befindet sich die Klemmbolzenvorrichtung 53 in der ersten Endposition in Anlage am Deckel 11. Der Drücker 49 ragt nun lediglich geringfügig aus der Öffnung 51 in der Bodenplatte 9 vor. Wie insbesondere in Fig. 3b zu erkennen ist, greifen die Zähne 55 der Klemmbolzen 39, 41, 43, 45 lediglich geringfügig in den im zugeordneten Kanal 23, 25, 27, 29 angeordneten Schnürsenkel 24, 26, 28, 30 ein, sodass dieser ohne oder lediglich mit geringem Widerstand in Richtung der Bodenplatte 9 der Klemmvorrichtung (d.h. in der Zeichnungsebene nach links), wie durch den Pfeil in Fig. 3b gezeigt ist, gezogen werden kann. Durch die Zähne 55 des Klemmbolzens 39, 41, 43, 45 wird lediglich ein geringer Reibungswiderstand auf den jeweiligen Schnürsenkel 24, 26, 28, 30 ausgeübt.The two end positions, between which the clamping bolt device 53 can be moved in the housing 1, are in the Fig. 3a and 3b or 4a and 4b shown. As in Fig. 3a and Fig. 3b can be seen, the clamping bolt device 53 is in the first end position in contact with the lid 11. The pusher 49 now protrudes only slightly from the opening 51 in the bottom plate 9. As in particular in Fig. 3b can be seen, engage the teeth 55 of the clamping bolt 39, 41, 43, 45 only slightly in the associated channel 23, 25, 27, 29 arranged shoelaces 24, 26, 28, 30, so that this with little or no resistance in the direction of the bottom plate 9 of the clamping device (ie to the left in the plane of the drawing), as indicated by the arrow in FIG Fig. 3b shown can be pulled. By the teeth 55 of the clamping bolt 39, 41, 43, 45 only a small frictional resistance to the respective lace 24, 26, 28, 30 is exercised.

In der in Fig. 4a gezeigten Endposition befindet sich die Klemmbolzenvorrichtung 53 in Anlage an der Bodenplatte 9 der Klemmvorrichtung. Der Drücker 49 der Klemmvorrichtung ragt nun deutlicher aus der entsprechenden Öffnung 51 in der Bodenplatte 9 der Klemmvorrichtung hervor. Aufgrund des verringerten Querschnitts des Kanals 23, 25, 27, 29 zwischen dem Klemmbolzen 39, 41, 43, 45 und der Rückwand 5 der Klemmvorrichtung in dieser Endposition greifen die Zähne 55 des Klemmbolzens 39, 41, 43, 45 nun stärker in den Schnürsenkel 24, 26, 28, 30 ein, sodass dieser bei einer Zugbelastung in Richtung der Bodenplatte 9 (d.h. in der Zeichnungsebene nach rechts) der Klemmvorrichtung festgeklemmt ist.In the in Fig. 4a shown end position, the clamping bolt device 53 is in contact with the bottom plate 9 of the clamping device. The pusher 49 of the clamping device now protrudes more clearly from the corresponding opening 51 in the bottom plate 9 of the clamping device. Due to the reduced cross section of the channel 23, 25, 27, 29 between the clamping bolt 39, 41, 43, 45 and the rear wall 5 of the clamping device in this end position, the teeth 55 of the clamping bolt 39, 41, 43, 45 now engage more strongly in the laces 24, 26, 28, 30, so that it is clamped at a tensile load in the direction of the bottom plate 9 (ie in the plane of the drawing to the right) of the clamping device.

Die Klemmvorrichtung ist für eine Befestigung an der Zunge eines Stiefels eingerichtet, wobei die Bodenplatte 9 der Klemmvorrichtung vorzugsweise nach unten und der Deckel 11 nach oben gerichtet ist. Die Fläche der Rückwand 5 der Klemmvorrichtung erstreckt sich über die Fläche der Vorderwand 3 hinaus und es sind darin Durchgangsöffnungen 57, 59, 61 ausgebildet, mit welchen die Klemmvorrichtung an der Zunge mit Nieten, Schrauben und ähnlichen Befestigungsmitteln befestigt werden kann.The clamping device is adapted for attachment to the tongue of a boot, wherein the bottom plate 9 of the clamping device is preferably directed downward and the lid 11 upwards. The surface of the rear wall 5 of the clamping device extends over the surface of the front wall 3 out and there are through holes 57, 59, 61 are formed, with which the clamping device can be attached to the tongue with rivets, screws and similar fastening means.

Die Funktionsweise der Klemmvorrichtung gemäß der gezeigten Ausführungsform wird im Folgenden beschrieben. Die vier Schnürsenkel 24, 26, 28, 30, die beispielsweise zwei Schnürungen eines Stiefels zugeordnet sein können, werden durch die Durchgangsöffnungen 15, 16, 17, 18, 19, 20, 21, 22 in der Bodenplatte 9 und im Deckel 11 geführt und dabei in den entsprechenden Kanälen 23, 25, 27, 29 angeordnet. Vorzugsweise werden die beiden Schnürsenkel 26, 28 der einen Schnürung durch die beiden innen liegenden Kanäle 25, 27 im Gehäuse 1 geführt und die beiden Schnürsenkel 24, 30 der anderen Schnürung durch die beiden außen liegenden Kanäle 23, 29. Beim Einführen der Schnürsenkel 24, 26, 28, 30 in die Kanäle 23, 25, 27, 29 und auch beim Spannen der Schnürungen über dem Fuß durch Ziehen an den Schnürsenkeln 24, 26, 28, 30 werden die den Kanälen 23, 25, 27, 29 zugeordneten Klemmbolzen 39, 41, 43, 45 und damit die gesamte Klemmbolzenvorrichtung 53 in Richtung des Deckels 11 der Klemmvorrichtung und gegebenenfalls bis zum Erreichen der Endposition mitgenommen, da die Zähne 55 der Klemmbolzen 39, 41, 43, 45 mit den Schnürsenkeln 24, 26, 28, 30 in Berührung kommen. Die Klemmbolzen 39, 41, 43, 45 befinden sich nun in einem Bereich der Kanäle 23, 25, 27, 29, in dem der Durchmesser oder die Höhe der Kanäle 23, 25, 27, 29 so groß ist, dass die Schnürsenkel 24, 26, 28, 30 ohne oder lediglich mit geringem Widerstand nach oben (in Fig. 3b nach links) gezogen werden können. In dieser Position der Klemmbolzen 39, 41, 43, 45 können die Schnürungen mit der gewünschten Stärke gespannt werden. Nach dem Straffen der Schnürungen werden die Schnürsenkel 24, 26, 28, 30 losgelassen, sodass sie durch die jetzt in den Schnürungen vorliegende Spannung nach unten (in Fig. 4b nach rechts) gezogen werden. Dabei werden die Klemmbolzen 39, 41, 43, 45 aufgrund der Reibung zwischen ihren Zähnen 55 und den Schnürsenkeln 24, 26, 28, 30 in Richtung der Bodenplatte 9 des Gehäuses 1 mitgenommen und dabei die Schnürsenkel 24, 26, 28, 30 zwischen den Klemmbolzen 39, 41, 43, 45 und den diesen gegenüberliegenden Wänden der Kanäle 23, 25, 27, 29 in den Bereichen der Kanäle 23, 25, 27, 29 mit verringertem Querschnitt festgeklemmt. Da der räumliche Abstand zwischen den beiden extremen Positionen der Klemmbolzenvorrichtung 53 lediglich einige Millimeter beträgt, wird die Spannung der Schnürung(en) beim Loslassen der Schnürsenkel 24, 26, 28, 30, nur geringförmig verringert, bevor die maximale Klemmwirkung erreicht wird.The operation of the clamping device according to the embodiment shown will be described below. The four laces 24, 26, 28, 30, which may for example be associated with two laces of a boot, are guided through the through openings 15, 16, 17, 18, 19, 20, 21, 22 in the bottom plate 9 and in the lid 11 and while in the corresponding channels 23, 25, 27, 29 are arranged. Preferably, the two laces 26, 28 of a lacing through the two inner channels 25, 27 are guided in the housing 1 and the two laces 24, 30 of the other lacing through the two outer channels 23, 29. When inserting the laces 24, 26, 28, 30 in the channels 23, 25, 27, 29 and also in tensioning the laces over the foot by pulling on the laces 24, 26, 28, 30 are the channels 23, 25, 27, 29 associated clamping bolt 39 , 41, 43, 45 and thus the entire clamping bolt device 53 in the direction of the lid 11 of the clamping device and possibly taken to reach the end position, since the teeth 55 of the clamping bolt 39, 41, 43, 45 with the laces 24, 26, 28, 30 come into contact. The clamping bolts 39, 41, 43, 45 are now in a region of the channels 23, 25, 27, 29, in which the diameter or the height of the channels 23, 25, 27, 29 is so large that the laces 24, 26, 28, 30 with no or only slight resistance upward (in Fig. 3b to the left). In this position, the clamping bolts 39, 41, 43, 45, the laces can be stretched with the desired strength. After tightening the laces, the laces 24, 26, 28, 30 are released so that they are lowered by the tension now present in the laces (in FIG Fig. 4b to the right). The clamping bolts 39, 41, 43, 45 due to the friction between their teeth 55 and the shoe laces 24, 26, 28, 30 taken in the direction of the bottom plate 9 of the housing 1 while the laces 24, 26, 28, 30 between the Clamping bolts 39, 41, 43, 45 and the opposite walls of the channels 23, 25, 27, 29 clamped in the areas of the channels 23, 25, 27, 29 with reduced cross-section. Since the spatial distance between the two extreme positions of the clamping bolt device 53 is only a few millimeters, the tension of the laces when the laces 24, 26, 28, 30 are released is only slightly reduced before the maximum clamping effect is achieved.

Das Lösen der Schnürsenkel 24, 26, 28, 30 erfolgt, indem die Klemmbolzenvorrichtung durch Drücken auf den Drücker 49 aus der zweiten Position in Richtung der ersten Position gedrückt wird, sodass die Klemmbolzen 39, 41, 43, 45 aus den Bereichen der Kanäle 23, 25, 27, 29 mit verringertem Durchmesser in die Bereiche der Kanäle 23, 25, 27, 29 mit vergrößertem Durchmesser verschoben und die Schnürsenkel 24, 26, 28, 30 freigegeben werden.The loosening of the laces 24, 26, 28, 30 takes place by pressing the clamping bolt device by pressing the pusher 49 from the second position in the direction of the first position, so that the clamping bolts 39, 41, 43, 45 from the areas of the channels 23rd , 25, 27, 29 reduced in diameter in the areas of the channels 23, 25, 27, 29 increased in diameter and the laces 24, 26, 28, 30 are released.

An der erfindungsgemäßen Vorrichtung können zahlreiche Modifizierungen vorgenommen werden, ohne den Umfang der Erfindung zu verlassen. Die Form des Gehäuses kann auf vielfältige Weise abgewandelt werden. Im Gehäuse könnten die Wände zwischen den Kanälen weggelassen werden. Es ist denkbar, bei einer Ausführungsform zur Fixierung von vier Schnürsenkeln lediglich jeweils zwei Klemmbolzen miteinander zu verbinden, sodass jeweils zwei Schnürsenkel, die jeweils einer Schnürung zugeordnet sind, unabhängig voneinander gelöst werden können. Entsprechend könnten die jeweils verbundenen Klemmbolzen mit jeweils einem Hebel oder Drücker versehen sein, um sie unabhängig voneinander zu betätigen.Numerous modifications can be made to the apparatus of the invention without departing from the scope of the invention. The shape of the housing can be modified in many ways. In the housing, the walls between the channels could be omitted. It is conceivable, in an embodiment for fixing four shoelaces only two clamping bolts to connect each other, so that two shoelaces, each associated with a lacing, can be solved independently. Accordingly, the respectively connected clamping bolts could be provided with a lever or pusher to actuate them independently of each other.

Darüber hinaus ist es denkbar, den Drücker 49 der Klemmbolzenvorrichtung an einer anderen Stelle vorzusehen und beispielsweise so am Steg anzuordnen, dass er durch eine entsprechende Öffnung im Deckel ragt oder aus der Vorderwand ragt.In addition, it is conceivable to provide the pusher 49 of the clamping bolt device at a different location and, for example, to arrange it on the web that it projects through a corresponding opening in the lid or protrudes from the front wall.
