Description

Die vorliegende Erfindung betrifft ein Steckschloss zum lösbaren Verbinden von zwei Gurtenden, insbesondere für einen Kletter-, Sicherheits- oder Rettungsgurt, mit einem Schlossteil und einem Steckteil, wobei das Schlossteil ein steckseitiges Ende zum Einstecken des Steckteiles und ein gurtseitiges Ende zum befestigen eines Gurtes aufweist, wobei das Steckteil eine Rastzunge aufweist, welche beim Einstecken des Steckteils in das Schlossteil in eine Einsteckrichtung mit einem ersten Rastmechanismus im Schlossteil derart einrastet, dass das Steckteil gegen ein Herausziehen aus dem Schlossteil entgegen der Einsteckrichtung in dem Schlossteil verriegelt ist, wobei die Einsteckrichtung von dem steckseitigen Ende des Schlossteils in Richtung gurtseitiges Ende des Schlossteils weist, gemäß dem Oberbegriff des Anspruchs 1, bekannt beispielsweise aus US-A-3 585 692 .The present invention relates to a plug lock for releasably connecting two strap ends, in particular for a climbing, safety or rescue harness, with a lock part and a male part, wherein the lock part has a plug-side end for insertion of the male part and a gurtseitiges end for attaching a belt , wherein the male part has a latching tongue which engages in the insertion part with a first latching mechanism in the lock part such that the male part against being pulled out of the lock part is locked against the insertion in the lock part, wherein the plug of the plug-side end of the lock part in the direction of the belt-side end of the lock member, according to the preamble of claim 1, known for example from US-A-3,585,692 ,

Steckverschlüsse für Gurtbänder sind beispielsweise aus dem Automobilbereich bekannt. Bei Gurtzeugen müssen die Verschlüsse so ausgebildet sein, dass diese nicht unbeabsichtigt während der Benutzung öffnen. Dies wird beispielsweise dadurch erreicht, dass zum Öffnen zwei Knöpfe gleichzeitig betätigt werden müssen. Ein derartiges Steckschloss ist beispielsweise aus der DE 196 47 631 A1 bekannt. Zum Herstellen der Verbindung wird ein Steckteil in ein Schlossteil eingesteckt, wobei Rastelemente vorgesehen sind, mit denen eine rastende Verbindung zwischen dem Steckteil und dem Schlossteil hergestellt wird. Es sind zwei Betätigungselemente vorgesehen, die entsprechende Rastelemente in eine Freigabestellung bewegen und gleichzeitig gedrückt werden müssen, um das Steckteil vom Schlossteil zu lösen. Hierbei ist es eine Eigenart von Steckschlössern, dass das Steckteil beim Lösen in die entgegengesetzte Richtung aus dem Schlossteil heraus gezogen wird, wie beim Einstecken in das Schlossteil. Zwar ist unter Last eine größere Kraft notwendig, um die Rastelemente mittels der Betätigungselemente in die Freigabestellung zu bewegen, jedoch ist nicht vollkommen ausgeschlossen, dass sich das Steckschloss unbeabsichtigt öffnet, wenn eine entsprechend große Kraft auf die Betätigungselemente wirkt.Fasteners for straps are known for example from the automotive sector. For harnesses, the closures must be designed so that they do not inadvertently open during use. This is achieved, for example, by opening two buttons simultaneously. Such a lock is for example from the DE 196 47 631 A1 known. To make the connection, a male part is inserted into a lock part, wherein locking elements are provided with which a latching connection between the male part and the lock part is made. There are two actuators provided to move the corresponding locking elements in a release position and must be pressed simultaneously to the To remove the plug-in part from the lock part. It is a peculiarity of plug locks that the male part is pulled out of the lock part when loosening in the opposite direction, as when plugging into the lock part. Although under load a larger force is necessary to move the locking elements by means of the actuators in the release position, but is not completely excluded that the lock opens unintentionally when a correspondingly large force acts on the actuators.

Als alternative hierzu mit höherer Sicherheit gegen unbeabsichtigtes Öffnen bieten Verschlüsse, bei denen ein Einhängeteil in das Schlossteil eingehängt wird. Ein derartiges Einhängeschloss ist aus der US 6 802 109 B2 bekannt. Die Besonderheit liegt darin, dass das Einhängen in dieselbe Richtung erfolgt, in die bei der Benutzung eine Kraft auf die Schlossteile wirkt. Dadurch zieht die auf die Schlossteile wirkende Kraft das Schloss immer in Schließrichtung. Zum Öffnen bzw. Lösen des Einhängeteils vom Schlossteil ist eine Entriegelung zu betätigen und das Einhängeteil entgegen der Einhängerichtung relativ zum Schlossteil zu bewegen.As an alternative to this with greater security against unintentional opening offer closures in which a hanging part is hooked into the lock part. Such a padlock is from the US 6,802,109 B2 known. The peculiarity is that the suspension takes place in the same direction in which a force acts on the lock parts during use. As a result, the force acting on the lock parts always pulls the lock in the closing direction. To open or release the hooking part of the lock part, an unlocking is to be actuated and to move the hooking part against the hooking direction relative to the lock part.

Aus der DE 20 2004 017 043 U1 ist ein Gurtschloss für Klettergurte bekannt, bei dem der Verriegelungsmechanismus mit zwei Betätigungselementen zum Lösen der Verriegelung derart ausgebildet ist, dass sich die Betätigungselemente nicht in die Lösestellung drücken lassen, wenn auf das Gurtschloss eine Kraft in Richtung entgegen der Einsteckrichtung wirkt. Allerdings ist das beabsichtigte Lösen bzw. Öffnen des Gurtschlosses umständlich, da hierzu das Schlossteil und das Steckteil gegeneinander und gleichzeitig die beiden Betätigungselemente gedrückt und gehalten werden müssen.From the DE 20 2004 017 043 U1 a buckle for climbing harness is known in which the locking mechanism with two actuators to release the lock is designed such that the actuators can not be pushed into the release position when the buckle force in the direction opposite to the insertion acts. However, the intended release or opening of the buckle is cumbersome because this the lock part and the male part against each other and at the same time the two actuators must be pressed and held.

Der Erfindung liegt die Aufgabe zugrunde, ein Steckschloss der o.g. Art hinsichtlich der Funktionssicherheit und des Bedienungskomforts zu verbessern. Insbesondere soll der Schutz gegen ein unbeabsichtigtes Öffnen des Steckschlosses verbessert werden.The invention has for its object to improve a plug lock of the type mentioned above in terms of reliability and ease of use. In particular, the protection against unintentional opening of the plug lock should be improved.

Diese Aufgabe wird erfindungsgemäß durch ein Steckschloss der o.g. Art mit den in Anspruch 1 gekennzeichneten Merkmalen gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den weiteren Ansprüchen beschrieben.This object is achieved by a key lock of o.g. Art solved with the features characterized in claim 1. Advantageous embodiments of the invention are described in the further claims.

Bei einem Steckschloss der o.g. Art ist es erfindungsgemäß vorgesehen, dass der erste Rastmechanismus nach einem Einrasten zwischen Steckteil und Schlossteil manuell unlösbar ausgebildet ist und im Schlossteil ein zweiter manuell lösbarer Rastmechanismus derart angeordnet und ausgebildet ist, dass dieser zweite Rastmechanismus in einem verriegelten Zustand eine Bewegung des in das Schlossteil eingesteckten Steckteils relativ zum Schlossteil in Einsteckrichtung blockiert und in einem entriegelten Zustand eine Bewegung des in das Schlossteil eingesteckten Steckteils relativ zum Schlossteil in Einsteckrichtung erlaubt, so dass das Steckteil vom Schlossteil mittels Ausschieben in Einsteckrichtung lösbar ist.In a lock of the o.g. Art it is inventively provided that the first locking mechanism is manually unsolvable after a snap between male and male part and the lock part a second manually releasable locking mechanism arranged and designed such that this second locking mechanism in a locked state, a movement of the inserted into the lock part Blocked plug relative to the lock part in the insertion direction and in an unlocked state, a movement of the plugged into the lock part plug relative to the lock part in the insertion allowed, so that the male part of the lock part by means of pushing out in the insertion direction is solvable.

Dies hat den Vorteil, dass trotz einfacher Herstellung der Verbindung zwischen Steckteil und Schlossteil durch einfaches Einstecken des Steckteils in das Schlossteil ein Lösen des Steckteils entgegen der Einsteckrichtung unter Last ausgeschlossen ist, so dass ein unbeabsichtigtes Öffnen des Steckschlosses unter Last wirksam vermieden ist. Gleichzeitig ist ein Lösen von Steckteil und Schlossteil, wie bei einem Einhängeschloss, vorgesehen. Dadurch verbindet das neuartige Steckschloss die Vorteile eines Steckschlosses, nämlich das schnelle und einfache Schließen des Schlosses durch Einstecken in Einsteckrichtung, mit den Vorteilen eines Einhängeschlosses, nämlich die vollständige Sicherung gegen ein Lösen von Steckteil und Schlossteil entgegen der Steckrichtung unter Last, ohne dabei den Nachteil des aufwändigeren Einhängens, wie bei einem Einhängeschloss, in Kauf nehmen zu müssen.This has the advantage that, despite simple production of the connection between plug-in part and lock part by simply inserting the male part in the lock part a release of the male part against the insertion is excluded under load, so that unintentional opening of the lock plug under load is effectively avoided. At the same time a release of male part and lock part, as in a padlock, provided. As a result, the novel key lock combines the advantages of a key lock, namely the quick and easy closing of the lock by plugging in the insertion, with the advantages of a padlock, namely the complete protection against loosening of male part and lock part against the direction of insertion under load, without the disadvantage the more expensive hooking, as in a padlock, to accept.

In einer bevorzugten Ausführungsform weist der erste Rastmechanismus wenigstens eine, insbesondere zwei, an der Rastzunge angeordnete Rastnasen auf, die jeweils um eine Schwenkachse verschwenkbar ist, wobei die Rastnase in Richtung einer Verriegelungsstellung mit einer elastischen Vorspannkraft beaufschlagt ist und aus dieser Verriegelungsstellung durch Schwenken um die jeweilige Schwenkachse entgegen der Vorspannkraft elastisch federnd auslenkbar ist, wobei am Schlossteil zu jeder Rastnase ein starrer Rasthaken derart ausgebildet und angeordnet ist, dass nach dem Einstecken des Steckteils in das Schlossteil jeweils eine Rastnase mit einem zugeordneten Rasthaken zusammenwirkend eine Rastverbindung herstellt.In a preferred embodiment, the first latching mechanism has at least one, in particular two, latching lugs arranged on the latching tongue, which are each pivotable about a pivot axis, wherein the latching lug is acted upon in the direction of a locking position with an elastic biasing force and from this locking position by pivoting about the respective pivot axis is resiliently deflectable against the biasing force, wherein on the lock part to each locking lug a rigid latching hook is designed and arranged such that after insertion of the male part in the lock part in each case a latching nose with an associated latching hook cooperatively produces a latching connection.

Ein automatisches Auslenken der Rastnase entgegen der elastischen Vorspannkraft beim Einstecken des Steckteils in das Schlossteil wird dadurch erzielt, dass die Rastnase jeweils eine schräge Fläche aufweist, welche sich in Richtung entgegen der Einsteckrichtung ansteigend erhebt.An automatic deflection of the locking lug against the elastic biasing force when inserting the male part in the lock part is achieved in that the locking lug each having an inclined surface which rises in the direction opposite to the plugging rising.

In einer besonders bevorzugten Ausführungsform sind am Steckteil zwei Rastnasen und am Schlossteil zwei Rasthaken angeordnete, wobei die zwei Rasthaken als jeweilige U-förmige Erhebungen an dem steckseitigen Ende des Schlossteils ausgebildet sind.In a particularly preferred embodiment, two latching lugs are arranged on the plug-in part and two latching hooks on the latching part, wherein the two latching hooks are formed as respective U-shaped elevations on the plug-side end of the latching part.

Um dem Steckteil beim Ausschieben aus dem Schlossteil in Einsteckrichtung ausreichend Freiraum zur Verfügung zu stellen, weist jeweils ein Schenkel der U-förmigen Erhebungen ein freies Ende auf, wobei die Schenkel der U-förmigen Erhebungen mit freiem Ende derart voneinander beabstandet angeordnet sind, dass ein Abstand zwischen diesen Schenkeln der U-förmigen Erhebungen gleich oder größer als eine Breite der Rastzunge des Steckteils ist.To the plug-in part when pushing out of the lock part in the insertion sufficient clearance available, each has a leg of the U-shaped elevations a free end, wherein the legs of the U-shaped elevations are arranged with free end spaced apart such that a Distance between these legs of the U-shaped elevations is equal to or greater than a width of the latching tongue of the male part.

Ein Einstecken des Steckteils in das Schlossteil ohne gegenseitiges Verkanten erzielt man dadurch, dass die Rastzunge eine parallel zur Einsteckrichtung verlaufende Erhebung und das Schlossteil eine parallel zur Einsteckrichtung verlaufende Nut aufweist, wobei die Erhebung und die Nut derart angeordnet und ausgebildet sind, dass beim Einstecken des Steckteils in das Schlossteil die Erhebung in die Nut eingreift und dadurch das Steckteil relativ zum Schlossteil führt.An insertion of the male part in the lock part without mutual tilting is achieved in that the latching tongue has a parallel to the insertion direction elevation and the lock part has a groove parallel to the insertion direction, wherein the elevation and the groove are arranged and designed such that upon insertion of the Plug-in part in the lock part engages the survey in the groove and thereby performs the male part relative to the lock part.

Zum automatischen Verriegeln des zweiten Rastmechanismus ist der zweite Rastmechanismus in Richtung der Verriegelungsstellung mit einer elastischen Federvorspannkraft beaufschlagt. Hierbei ist der zweite Rastmechanismus derart angeordnet und ausgebildet, dass dieser manuell entgegen der elastischen Federvorspannkraft in den entriegelten Zustand bewegbar ist.For automatically locking the second locking mechanism, the second locking mechanism is acted upon in the direction of the locking position with an elastic spring biasing force. Here, the second locking mechanism is such arranged and formed so that it is manually movable against the elastic spring biasing force in the unlocked state.

An insertion direction 36, i. a direction in which the male part 12 is inserted into the lock part 10 is directed from the plug-side end 20 of the lock part 10 in the direction of the belt-side end 22 of the lock part 10.

Das Steckteil 12 umfasst eine Gurtöffnung 26 mit Gurtfeststellung 27, Stanzteile 28 und gegenüberliegen an der Rastzunge 14 angeordnete Rastnasen 30, welche jeweils um eine Schwenkachse 32 aus einer in der Fig. 1 dargestellten Verriegelungsposition gegen eine elastische Federkraft aufeinander zu verschwenkbar sind. Jede Rastnasen 30 weist eine schräge Fläche 34 auf, die sich in Richtung entgegengesetzt der Einsteckrichtung 36 ansteigend, d.h. die Breite der Rastzunge 14 zunehmend überragend, erhebt.The male part 12 comprises a belt opening 26 with Gurtfeststellung 27, punched parts 28 and opposite to the latching tongue 14 arranged latching lugs 30, which in each case about a pivot axis 32 of a in the Fig. 1 shown locking position against an elastic spring force are pivoted toward each other. Each locking lugs 30 has an inclined surface 34 which rises in the direction opposite to the insertion direction 36, ie the width of the locking tongue 14 increasingly towering, rises.

Um das Einstecken des Steckteils 12 in das Schlossteil 10 zu führen, weist das Steckteil 12 eine parallel zur Einsteckrichtung 35 verlaufende Erhebung 38 und das Schlossteil 10 eine Führungsnut 40 auf, wobei beim Einstecken des Steckteils 12 in das Schlossteil 10 die Erhebung 38 in die Führungsnut 40 greift und des Steckteil 12 relativ zum Schlossteil 10 führt.To guide the insertion of the male part 12 in the lock part 10, the male part 12 has a parallel to the insertion direction 35 extending survey 38 and the lock part 10 a guide groove 40, wherein upon insertion of the male part 12 in the lock part 10, the survey 38 in the guide 40 attacks and the male part 12 leads relative to the lock part 10.

Am Schlossteil 10 sind am steckseitigen Ende 20 zwei U-förmige Erhebungen 42 ausgebildet, die jeweils einen freien Schenkel 44 aufweisen. Die U-förmigen Erhebungen 42 sind derart angeordnet und ausgebildet, dass diese bei Einstecken des Steckteils 12 in das Schlossteil 10 zunächst auf die schrägen Flächen 34 wirken und dadurch die Rastnasen 30 um die Schwenkachsen 32 verschwenken. Sobald die Rastnasen 30 die U-förmigen Erhebungen 42 passiert haben, schnappen diese unter Einwirkung der elastischen Federkraft zurück in die in den Fig. dargestellte Rastposition und Rasten an den U-förmigen Erhebungen 42 ein. Mit anderen Worten wirken die Rastnasen 30 und die U-förmigen Erhebungen 42 derart zusammen, dass ein Ausstecken bzw. Herausziehen des Steckteils 12 aus dem Schlossteil 10 in Richtung entgegengesetzt zur Einsteckrichtung 36 verhindert ist.At the lock part 10, two U-shaped elevations 42 are formed at the plug-in end 20, each having a free leg 44. The U-shaped elevations 42 are arranged and designed such that they initially act upon insertion of the male part 12 in the lock part 10 on the inclined surfaces 34 and thereby pivot the locking lugs 30 about the pivot axes 32. As soon as the latching lugs 30 have passed the U-shaped elevations 42, they snap back under the action of the elastic spring force into the latching position and detents on the U-shaped elevations 42 shown in FIGS. In other words, the latching lugs 30 and the U-shaped elevations 42 cooperate in such a way that unplugging or pulling out of the plug-in part 12 from the lock part 10 in the direction opposite to the insertion direction 36 is prevented.

Der aus Rastnasen 30 und U-förmigen Erhebungen 42 zusammengesetzte erste Rastmechanismus hält somit das Steckteil 12 im Schlossteil 10 fest, wobei keinerlei Lösemittel vorgesehen sind, um die Verrastung zwischen den Rastnasen 30 und den U-förmigen Erhebungen 42 zu lösen. Ein Ausstecken bzw. Herausziehen des Steckteils 12 aus dem Schlossteil 10 in Richtung entgegengesetzt zur Einsteckrichtung 36 ist ausgeschlossen. Hierdurch ist auch ein unbeabsichtigtes Lösen des Steckteils 12 vom Schlossteil 10 in Richtung entgegengesetzt zur Einsteckrichtung 36 in jedem Falle ausgeschlossen.The latching lugs 30 and U-shaped projections 42 first latching mechanism thus holds the male part 12 in the lock part 10 fixed, with no solvents are provided to release the locking between the locking lugs 30 and the U-shaped projections 42. Unplugging or pulling out of the male part 12 from the lock part 10 in the direction opposite to the insertion direction 36 is excluded. As a result, inadvertent release of the male part 12 from the lock part 10 in the direction opposite to the insertion direction 36 is excluded in any case.

Erfindungsgemäß ist zusätzlich am Schlossteil 10 ein zweiter Rastmechanismus 46 vorgesehen, welcher in einer Raststellung oder Verriegelungsposition eine Relativbewegung des in das Schlossteil 10 eingesteckten Steckteils 12 in Richtung der Einsteckrichtung 36 verhindert, so dass das Steckteil 12 fest mit dem Schlossteil 10 verbunden ist. Der zweite Rastmechanismus 46 ist derart ausgebildet und angeordnet, dass dieser in einer Lösestellung oder Entriegelungsposition eine Relativbewegung des in das Schlossteil 10 eingesteckten Steckteils 12 in Richtung der Einsteckrichtung 36 erlaubt. Gleichzeitig ist zwischen den freien Schenkeln 44 der U-förmigen Erhebungen 42 ein derartiger Freiraum ausgebildet, dass die Rastzunge 14 durch diesen Freiraum hindurch passt. In der Folge kann bei Verstellen des zweiten Rastmechanismus 46 in die Lösestellung das Steckteil 12 in Richtung der Einsteckrichtung 36 aus dem Schlossteil 10 ausgehängt und damit vom Schlossteil 10 gelöst werden. Der zweite Rastmechanismus 46 ist in Richtung der Raststellung oder Verriegelungsposition mit einer elastischen Federkraft beaufschlagt, so dass sich dieser selbsttätig in die Raststellung bewegt.According to the invention a second locking mechanism 46 is additionally provided on the lock part 10, which prevents a relative movement of the plugged into the lock part 10 plug member 12 in the direction of insertion 36 in a locking position or locking position, so that the male part 12 is fixedly connected to the lock part 10. The second latching mechanism 46 is formed and arranged that this allows in a release position or unlocking a relative movement of the inserted into the lock part 10 plug-in part 12 in the direction of insertion 36. At the same time, such a clearance is formed between the free legs 44 of the U-shaped elevations 42 such that the latching tongue 14 fits through this clearance. As a result, when plugging in the second latching mechanism 46 into the release position, the plug-in part 12 can be unhooked in the direction of the plug-in direction 36 from the lock part 10 and thus released from the lock part 10. The second detent mechanism 46 is acted upon in the direction of the detent position or locking position with an elastic spring force, so that it moves automatically into the detent position.

Somit besteht die einzige Möglichkeit zum Lösen des Steckteils 12 vom Schlossteil 10 in einer Relativbewegung des Steckteils 12 relativ zum Schlossteil 10 in Einsteckrichtung 36, d.h. in Richtung entgegengesetzt zu einer Zugrichtung, die bei Benutzung auf das Steckschloss wirkt. Mit anderen Worten wirkt unter Last auf dem Steckschloss eine Zugrichtung entgegengesetzt zu einer Öffnungsrichtung.Thus, the only way to release the male part 12 from the lock part 10 in a relative movement of the male part 12 relative to the lock part 10 in the insertion direction 36, i. in the direction opposite to a pulling direction, which acts in use on the lock plug. In other words, a pull direction acts opposite to an opening direction under load on the plug lock.

Insgesamt vereint somit das erfindungsgemäße Steckschloss die Vorteile eines Steckschlosses mit schneller Herstellung der Verbindung zwischen Steckteil 12 und Schlossteil 10 durch einfaches Einstecken mit den Vorteilen eines Einhängeschlosses, bei dem eine auf das Schloss wirkende Kraft entgegen der Öffnungsrichtung wirkt. Andererseits ist ein Nachteil des Einhängeschlosses vermieden, nämlich der gegenüber dem Steckschloss aufwändigere Vorgang zum Verbinden der Schlossteile miteinander. Die Besonderheit des erfindungsgemäßen Steckschlosses liegt dabei darin, dass zum Lösen des Steckteils 12 von Schlossteil 10 das Steckteil 12 in Einsteckrichtung 36 aus dem Schlossteil 10 ausgeschoben wird. Das Verbinden und Lösen von Schlossteil 10 und Steckteil 12 erfolgt somit mittels einer Bewegung des Steckteils relativ zum Schlossteil in dieselbe Richtung, nämlich die Einsteckrichtung 36.Overall, the plug-in lock according to the invention thus combines the advantages of a plug-in lock with rapid production of the connection between plug-in part 12 and lock part 10 by simply plugging in the advantages of a padlock in which a force acting on the lock counteracts the opening direction. On the other hand, a disadvantage of the padlock is avoided, namely the opposite of the plug lock complex process for connecting the lock parts together. The peculiarity of the plug-in lock according to the invention lies in the fact that for releasing the plug-in part 12 of the lock part 10, the plug-in part 12 is pushed out of the lock part 10 in the insertion direction 36. The connection and release of the lock part 10 and plug-in part 12 thus takes place by means of a movement of the plug-in part relative to the lock part in the same direction, namely the insertion direction 36.

Die dargestellte Ausführungsform ist lediglich beispielhaft. In einer alternativen Ausführungsform können die beweglichen Rastnasen auch am Schlossteil 10 und entsprechende, mit den beweglichen Rastnasen zusammenwirkende starre Rasthaken am Steckteil 12 angeordnet sein.The illustrated embodiment is merely exemplary. In an alternative embodiment, the movable locking lugs on the lock part 10 and corresponding, cooperating with the movable locking lugs rigid latching hooks may be arranged on the plug-in part 12.
