Durch die Möglichkeit der Montage des als Klemmsteg ausgeführten Befestigungsbauteils an der Gurtschnalle mittels Aufschwenken können sowohl der Klemmsteg selbst als auch der mit ihm zusammenwirkende Gegensteg des Gurtbefestigungselementes relativ massiv und stark ausgebildet werden, ohne dass dies gleich zu einer besonders mächtigen bzw. dicken Ausführung der gesamten Gurtschnalle führt.Due to the possibility of mounting the fastening component designed as a clamping web on the belt buckle by pivoting both the terminal web itself and the cooperating with him webbing of the Gurtbefestigungselementes can be relatively solid and strong, without this being equal to a particularly powerful or thick design of the entire Belt buckle leads.

Das Vorspannelement und das Verriegelungselement sind durchgehend als ein Teil gefertigt.The biasing member and the locking member are continuously made as a part.

Durch die einstückige Anordnung des Vorspannelements am Befestigungsbauteil wird die Zahl der Teile reduziert. Darüber hinaus vereinfacht sich auch der Zusammenbau der Gurtschnalle.By the one-piece arrangement of the biasing member on the fastening component, the number of parts is reduced. In addition, also simplifies the assembly of the buckle.

Besonders preisgünstig und einfach in der Herstellung ist es, das Vorspannelement und das Befestigungsbauteil als ein durchgehendes Kunststoffteil auszuführen. Z.B. ist es in diesem Zusammenhang möglich, Vorspannelemente und Befestigungsbauteile als einstückiges Kunststoffspritzgussteil herzustellen.Particularly inexpensive and easy to manufacture is to perform the biasing member and the fastening component as a continuous plastic part. For example, In this context, it is possible to produce biasing elements and fastening components as a one-piece plastic injection-molded part.

Grundsätzlich können verschiedene Arten von Vorspannelementen erfindungsgemäß einstückig an verschiedenen Arten von Befestigungsbauteilen der Gurtschnalle vorgesehen sein. Besonders einfach herzustellende Varianten sehen in diesem Zusammenhang vor, dass das Vorspannelement als eine, zumindest im unbelasteten Zustand vom Befestigungsbauteil abstehende Federzunge ausgebildet ist.In principle, various types of biasing elements may be integrally formed on different types of fastening components of the buckle according to the invention be provided. Particularly easy to manufacture variants provide in this context that the biasing element is designed as a, at least in the unloaded state protruding from the fastening component spring tongue.

Bevorzugte Varianten bestehen darin, dass die Gurtschnalle Kunststoff aufweist oder vollständig daraus besteht. Es sei aber auch darauf hingewiesen, dass erfindungsgemäße Gurtschnallen auch aus anderen Materialien hergestellt werden können. So kann es sich z.B. um Gurtschnallen aus Metall und Kunststoff oder auch um reine Metallschnallen handeln.Preferred variants are that the buckle plastic has or consists entirely of plastic. It should also be noted that inventive buckles can be made of other materials. So it can be e.g. to act buckles of metal and plastic or even pure metal buckles.

Der Vollständigkeit halber wird darauf hingewiesen, dass eine Gurtschnalle im Allgemeinen ein Bauteil ist, welches dazu dient, einen Gurt oder ein Band an einem Gegenstand und insbesondere an einem anderen Gurt oder Band zu befestigen. Der Gurt bzw. das Band wird dabei mittels des Gurtbefestigungselements an der Gurtschnalle befestigt. Sowohl die Art der Gurtschnalle als auch des Gurtbefestigungselements kann sehr unterschiedlich ausgestaltet sein. Es kann sich um Gurtschnallen handeln, welche zwei- oder mehrteilig aufgebaut sind, wobei ein erstes Teil der Gurtschnalle ein erstes Gurtbefestigungselement für einen ersten Gurt und zumindest ein weiterer Schnallenteil zumindest ein weiteres Gurtbefestigungselement für zumindest einen weiteren Gurt aufweist, wobei die Schnallenteile lösbar aneinander befestigbar bzw. miteinander verriegelbar sein können. Bei solchen Ausgestaltungsformen können andere Befestigungsbauteile als Verriegelungshebel ausgebildet sein, mit welchem die Schnallenteile lösbar aneinander befestigbar bzw. verriegelbar sind.For the sake of completeness, it should be understood that a buckle is generally a component used to attach a strap or strap to an object, and in particular to another strap or strap. The belt or the band is thereby fastened by means of the Gurtbefestigungselements on the buckle. Both the type of buckle and the Gurtbefestigungselements can be designed very different. It may be belt buckles, which are constructed in two or more parts, wherein a first part of the buckle has a first Gurtbefestigungselement for a first strap and at least one other buckle part at least one further Gurtbefestigungselement for at least one other strap, wherein the buckle parts detachably fastened to each other or can be locked together. In such embodiments, other fastening components may be formed as a locking lever, with which the buckle parts are releasably fastened to one another or lockable.

Besonders bevorzugte Ausgestaltungsformen sehen vor, dass die Gurtschnalle zumindest ein männliches Schnallenteil und zumindest ein weibliches Schnallenteil aufweist, wobei das männliche Schnallenteil und das weibliche Schnallenteil voneinander trennbar und mittels des als Verriegelungshebel ausgebildeten anderen Befestigungsbauteils oder zumindest eines der als Verriegelungshebel ausgebildeten anderen Befestigungsbauteile ineinander oder aneinander verriegelbar sind.Particularly preferred embodiments provide that the buckle has at least one male buckle part and at least one female buckle part, wherein the male buckle part and the female buckle part separable from each other and by means of the other fastening component designed as a locking lever or at least one of the other fastening components formed as locking lever into each other or to each other are lockable.

Um hier eine sehr stabile, auch bei großer Krafteinwirkung von außen einsetzbare und trotzdem schlank baubare Gurtschnalle bereitzustellen, sehen in diesem Zusammenhang bevorzugte Ausgestaltungsformen der Erfindung vor, dass zumindest eines, vorzugsweise jedes, der als Verriegelungshebel ausgebildeten anderen Befestigungsbauteile in der Verriegelungsstellung, in der das männliche Schnallenteil und das weibliche Schnallenteil ineinander oder aneinander verriegelt sind, bei einem Zug in zumindest eine Trennrichtung, in der das männliche Schnallenteil und das weibliche Schnallenteil voneinander trennbar sind, vorzugsweise ausschließlich, auf Druck belastet ist. Die Trennrichtungen sind dabei die Richtungen, in denen das männliche und/oder weibliche Schnallenteil vom jeweils anderen Schnallenteil abgezogen wird bzw. werden, um diese beiden Schnallenteile voneinander zu trennen. Treten in der Verriegelungsstellung im Wesentlichen oder vorzugsweise ausschließlich nur Druckkräfte am Verriegelungshebel auf, so kann dieser hohe Lasten aufnehmen ohne besonders groß gebaut sein zu müssen. Es kann z.B. vorgesehen sein, dass zumindest eines, vorzugsweise jedes, der als Verriegelungshebel ausgebildeten anderen Befestigungsbauteile um eine Schwenkachse schwenkbar gelagert ist und in der Verriegelungsstellung, in der das männliche Schnallenteil und das weibliche Schnallenteil ineinander oder aneinander verriegelt sind, eine Verriegelungsschulter eines Einschubankers des männlichen Schnallenteils hintergreift, wobei die Verriegelungsschulter beim Trennen des männlichen Schnallenteils vom weiblichen Schnallenteil an der Schwenkachse vorbei zu bewegen ist. Hierdurch wird erreicht, dass der Verriegelungshebel nur auf Druck belastet ist, wenn er sich in der Verriegelungsstellung befindet und an zumindest einem der Schnallenteile in der jeweiligen Trennrichtung gezogen wird.In order to provide here a very stable, even with great force externally usable and still slim buildable buckle, in this context, preferred embodiments of the invention provide that at least one, preferably each, designed as a locking lever other fastening components in the locking position in which the male buckle part and the female buckle part are interlocked or locked together in a train in at least one separating direction in which the male buckle part and the female buckle part are separable from each other, preferably exclusively, is subjected to pressure. The separation directions are the directions in which the male and / or female buckle part is subtracted from the other buckle part or are to separate these two buckle parts from each other. Occur in the locking position substantially or preferably exclusively only compressive forces on the locking lever, so it can absorb high loads without having to be particularly large. It can e.g. be provided that at least one, preferably each, the locking lever designed as other fastening components is pivotally mounted about a pivot axis and in the locking position in which the male buckle part and the female buckle part are locked together or one another, engages behind a locking shoulder of a push-in anchor of the male buckle part wherein the locking shoulder when separating the male buckle part from the female buckle part is to be moved past the pivot axis. This ensures that the locking lever is loaded only on pressure when it is in the locking position and is pulled on at least one of the buckle parts in the respective separation direction.

Die Erfindung kann aber auch bei Gurtschnallen, welche nur aus einem Schnallenteil, vorzugsweise mit einem oder mehreren Gurtbefestigungselementen, bestehen, umgesetzt werden.However, the invention can also be implemented in buckles, which consist only of a buckle part, preferably with one or more Gurtbefestigungselementen.

Es ist z.B. möglich, dass der Klemmsteg Führungsstege aufweist, mit denen er, vorzugsweise linear, verschiebbar in Führungsstegaufnahmen des Gurtbefestigungselements gelagert ist, wobei die Führungsstegaufnahmen und/oder die Führungsstege, in einem Schnitt gesehen, jeweils einen einseitig, vorzugsweise keilförmig, aufgeweiteten Querschnitt aufweisen. Der aufgeweitete Querschnitt der Führungsstegaufnahmen und/oder Führungsstege erlaubt die Schwenkbewegung beim Aufschwenken des als Klemmsteg ausgeführten Befestigungsbauteils. Besonders günstig ist es, wenn der aufgeweitete Querschnitt keilförmig ausgebildet ist.It is possible, for example, for the clamping web to have guide webs with which it is mounted, preferably linearly, displaceably in guide web receivers of the belt fastening element, wherein the guide web receptacles and / or the guide webs, seen in a section, each having a one-sided, preferably wedge-shaped, expanded cross-section. The widened cross section of the guide web receptacles and / or guide webs allows the pivoting movement during pivoting of the fastening component designed as a clamping web. It is particularly favorable if the widened cross-section is wedge-shaped.

In diesem Zusammenhang ist es auch günstig, wenn der Querschnitt der Führungsstegaufnahmen in einer, von dem Bereich zum Herumführen des Gurtes um den Klemmsteg weg weisenden Richtung aufgeweitet ist und/oder wenn der Querschnitt der Führungsstege in einer, zum Bereich zum Herumführen des Gurtes um den Klemmsteg hinweisenden Richtung aufgeweitet ist.In this connection, it is also advantageous if the cross section of the guide web receptacles is widened in a direction away from the area for moving the belt around the clamping web and / or if the cross section of the guide webs in one, the area around the belt around Clamping web pointing direction is widened.

Die Führungsstege stehen in bevorzugten Ausgestaltungsformen frei auskragend in Form von Stiften, also stiftartig von dem Bereich zum Herumführen des Gurtes um den Klemmsteg ab. Günstigerweise ist der Bereich zum Herumführen des Gurtes um den Klemmsteg bzw. das Befestigungsbauteil zwischen den Führungsstegen angeordnet. Bei diesen Varianten sind dann günstigerweise die Führüngsstegaufnahmen so angeordnet, dass der Gegensteg in dem Bereich, in dem er mit dem Gurt und dem Klemmsteg zusammenwirkt, durch die Führungsstegaufnahmen nicht geschwächt ist.The guide webs are in preferred embodiments cantilevered in the form of pins, so pin-like from the area for moving the belt around the clamping bar. Conveniently, the area for moving the belt around the clamping web or the fastening component is arranged between the guide webs. In these variants, the Führsstegsstegaufnahmen are then conveniently arranged so that the counterpart web is not weakened by the guide web recordings in the area in which he interacts with the belt and the clamping bar.

Der Vollständigkeit halber wird darauf hingewiesen, dass dem allgemeinen Sprachgebrauch folgend ein männliches Schnallenteil dadurch charakterisiert ist, dass es einen Fortsatz bzw. einen Einschubanker aufweist, mit dem es in eine entsprechende Aufnahmeausnehmung eines korrespondierenden weiblichen Schnallenteils einschiebbar und dort verriegelbar ist.For the sake of completeness, it is pointed out that, following the general usage, a male buckle part is characterized in that it has an extension or a push-in anchor, with which it can be inserted and locked into a corresponding receiving recess of a corresponding female buckle part.

Der Klemmsteg so wie auch das andere Befestigungsbauteil in Form des Verriegelungshebels sind in der Regel in irgendeiner Form bewegbar gelagert. Bevorzugte Ausgestaltungsformen sehen in diesem Zusammenhang vor, dass andere Befestigungsbauteil, vorzugsweise linear, verschiebbar und/oder verschwenkbar gelagert ist und/oder der Klemmsteg, vorzugsweise linear, verschiebbar gelagert ist. Das Vorspannelement kann dazu vorgesehen sein, den Klemmsteg und/oder das andere Befestigungsbauteil in Richtung hin zu seiner Klemmstellung oder seiner Verriegelungsstellung vorzuspannen.The clamping web as well as the other fastening component in the form of the locking lever are usually movably mounted in any form. Preferred embodiments provide in this context that other fastening component, preferably linearly, slidably and / or pivotally mounted is and / or the clamping bar, preferably linearly, slidably mounted. The biasing element can be provided to bias the clamping web and / or the other fastening component in the direction of its clamping position or its locking position.

Wenn das andere Befestigungsbauteil um eine Schwenkachse verschwenkbar gelagert ist, sehen bevorzugte Ausgestaltungsformen der Erfindung vor, dass die Schwenkachse zumindest einen äußeren Achsbolzen und zumindest ein inneres, vorzugsweise als Stift oder Schraube ausgeführtes, Einführteil aufweist, wobei das Einführteil in eine Ausnehmung im Achsbolzen einführbar bzw. eingeführt ist. Beim Einführen des Einführteils in die entsprechende Ausnehmung im Achsbolzen kann es zu einem leichten Aufspreizen des Achsbolzens kommen, sodass dieser dann entsprechend befestigt ist. Es können aber auch, gegebenenfalls zusätzlich, entsprechende Köpfe am Achsbolzen und auch am Einführteil vorgesehen sein. Trägt der Achsbolzen einen entsprechenden Kopf, so ist es günstig, wenn die Ausnehmung, in die das Einführteil einführbar ist, zur zum Kopf des Achsbolzens entgegen gesetzten Seite des Achsbolzens hin geöffnet ist.If the other fastening component is mounted so as to be pivotable about a pivot axis, preferred embodiments of the invention provide that the pivot axis has at least one outer axle pin and at least one inner insertion element, preferably designed as a pin or screw, wherein the insertion part can be inserted into a recess in the axle pin is introduced. When inserting the insertion in the corresponding recess in the axle bolt, it can lead to a slight spreading of the axle bolt, so that it is then secured accordingly. However, it is also possible, if appropriate in addition, to provide appropriate heads on the axle bolt and also on the insertion part. If the axle pin carries a corresponding head, then it is favorable if the recess into which the insertion part can be inserted is open towards the side of the axle bolt opposite the head of the axle bolt.

Wenn es sich um mehrteilige Schnallen mit zumindest einem weiblichen Schnallenteil und zumindest einem männlichen Schnallenteil handelt, ist es im Sinne einer flexiblen Einsetzbarkeit sinnvoll, wenn männliche und weibliche Schnallenteile mit voneinander verschieden breiten Gurtbefestigungselementen aneinander oder ineinander verriegelt werden können. Dies ermöglicht es, sehr flexibel Gurte und Bänder unterschiedlicher Breite miteinander zu verbinden. In diesem Sinne sieht ein erfindungsgemäßes Set mit zumindest einem weiblichen Schnallenteil und zumindest zwei männlichen Schnallenteilen vor, dass die männlichen Schnallenteile voneinander verschieden breite Gurtbefestigungselemente für voneinander verschieden breite Gurte aufweisen und im oder am selben weiblichen Schnallenteil verriegelbar sind. Ein solches Set kann aber auch mit zumindest einem männlichen Schnallenteil und zumindest zwei weiblichen Schnallenteilen ausgestattet sein, wobei die weiblichen Schnallenteile voneinander verschieden breite Gurtbefestigungselemente für voneinander verschieden breite Gurte aufweisen und am männlichen Schnallenteil verriegelbar sind. Hierdurch wird ein System geschaffen, bei welchem verschiedene Schnallenteile mit verschieden breiten Gurtbefestigungselementen für verschieden breite Gurte je nach Bedarf miteinander kombiniert werden können.When it comes to multi-part buckles with at least one female buckle part and at least one male buckle part, it makes sense in terms of flexible usability, when male and female buckles with each other different strap fasteners can be locked together or into each other. This makes it possible to very flexibly connect belts and belts of different widths. In this sense, a set according to the invention with at least one female buckle part and at least two male buckle parts provides that the male buckle parts from each other have different width Gurtbefestigungselemente for straps different widths and lockable in or on the same female buckle part. However, such a set can also be equipped with at least one male buckle part and at least two female buckle parts, wherein the female buckle parts from each other have different width Gurtbefestigungselemente for each different width straps and the male buckle part are lockable. As a result, a system is provided in which various buckle parts with different width Gurtbefestigungselementen for different width straps can be combined with each other as needed.

Weitere Einzelheiten und Merkmale bevorzugter Ausgestaltungsformen der Erfindung werden anhand der Figurenbeschreibung erläutert. Es zeigen:

  • Fig. 1 bis 17 verschiedene Ansichten zu einem ersten erfindungsgemäßen Ausführungsbeispiel einer Gurtschnalle;
  • Fig. 18 eine zweite erfindungsgemäße Ausführungsform einer Gurtschnalle;
  • Fig. 19 bis 26 weitere beispielhaft ausgewählte erfindungsgemäße Ausgestaltungsformen von Gurtschnallen.
Further details and features of preferred embodiments of the invention will be explained with reference to the description of the figures. Show it:
  • Fig. 1 to 17 different views of a first embodiment of a buckle according to the invention;
  • Fig. 18 a second embodiment of a buckle according to the invention;
  • FIGS. 19 to 26 further exemplified embodiments of buckles according to the invention.

Die Fig. 1 und 2 zeigen eine Rück- und eine Frontansicht auf eine erfindungsgemäß ausgebildet Gurtschnalle 1, welche ein männliches Schnallenteil 6 und ein weibliches Schnallenteil 7 aufweist. In den Fig. 1 und 2 ist das männliche Schnallenteil 6 mit seinem Einschubanker 14 vollständig in die entsprechende Aufnahmeausnehmung des weiblichen Schnallenteils 7 eingeführt und in dieser Stellung mittels der als Verriegelungshebel ausgeführten anderen Befestigungsbauteile 4 verriegelt, sodass das männliche Schnallenteil 6 nicht aus dem weiblichen Schnallenteil 7 herausgezogen werden kann. Zur Befestigung eines hier nicht gezeigten Bandes oder Gurtes 35 an der Gurtschnalle 1 weisen beide Schnallenteile 6 und 7 jeweils ein Gurtbefestigungselement 2 auf. Im gezeigten ersten Ausführungsbeispiel ist das Gurtbefestigungselement 2 des weiblichen Schnallenteils dazu vorgesehen, dass um den dort ausgebildeten Steg 20 ein Gurt 35 oder ein Band herumgezogen und dann z.B. durch Vernähen fixiert wird. Dies ist an sich bekannt und muss nicht weiter erläutert werden. Das Gurtbefestigungselement 2 des männlichen Schnallenteils 6 hingegen weist ein als Klemmsteg ausgebildetes erfindungsgemäßes Befestigungsbauteil 5 auf, um das der Gurt 35 oder das Band herumgeschlungen werden kann, um den Gurt 35 oder das Band verstellbar am Gurtbefestigungselement 2 und damit am männlichen Schnallenteil 6 zu befestigen. Zur Vorspannung dieses als Klemmsteg ausgeführten Befestigungsbauteiles 5 sind die besonders gut in Fig. 1 sichtbaren, hier in Form von Federzungen ausgebildeten Vorspannelemente 3 vorgesehen. Sie sind erfindungsgemäß einstückig am Befestigungsbauteil 5 angeordnet und drücken dieses in seine Klemmstellung, in der ein hier nicht dargestellter Gurt 35 vom Klemmsteg 5 gegen den fixen Gegensteg 21 des männlichen Schnallenteils 6 gedrückt wird. Zur Verstellung der Länge des um den Klemmsteg 5 herumgeführten Gurtes 35 wird der Klemmsteg 5, vorzugsweise linear, gegen die Vorspannung des Vorspannelementes 3 in Richtung hin zum Einschubanker 14 verschoben, sodass der Gurt 35 nicht mehr zwischen Klemmsteg 5 und Gegensteg 21 geklemmt ist und verstellt werden kann. Ist die Gurtverstellung erfolgt, so schiebt das Vorspannelement 3 den Klemmsteg 5 wieder in die Klemmstellung zurück. In dieser Klemmstellung verhindert der Klemmsteg 5 ein ungewolltes Verstellen des Gurtes 35 auch im lastfreien Zustand, in dem der Gurt 35 nicht unter Zugspannung steht.The Fig. 1 and 2 show a rear view and a front view of an inventively designed buckle 1, which has a male buckle part 6 and a female buckle part 7. In the Fig. 1 and 2 the male buckle part 6 is completely inserted with its insertion anchor 14 in the corresponding receiving recess of the female buckle part 7 and locked in this position by means of the other fastening components 4 designed as a locking lever, so that the male buckle part 6 can not be pulled out of the female buckle part 7. For fastening a belt or belt 35, not shown here, to the belt buckle 1, both buckle parts 6 and 7 each have a belt fastening element 2. In the first embodiment shown, the Gurtbefestigungselement 2 of the female buckle part is provided so that around the web 20 formed there, a belt 35 or a band pulled around and then fixed, for example by sewing. This is known per se and need not be explained further. The belt fastening element 2 of the male buckle part 6, however, has a fastening element 5 according to the invention designed as a clamping web, around which the belt 35 or the belt can be looped in order to fasten the belt 35 or the belt adjustably to the belt fastening element 2 and thus to the male buckle part 6. For biasing this designed as a clamping web fastening component 5 are particularly well in Fig. 1 visible, provided here in the form of spring tongues biasing elements 3. They are arranged integrally according to the invention on the fastening component 5 and press this in its clamping position in which a belt 35, not shown here, is pressed by the clamping web 5 against the fixed counterpart web 21 of the male buckle part 6. To adjust the length of the guided around the clamping web 5 belt 35 of the clamping web 5, preferably linear, is moved against the bias of the biasing member 3 in the direction of the insertion anchor 14, so that the belt 35 is no longer clamped between the clamping web 5 and the web 21 and adjusted can be. Once the belt adjustment has taken place, the pretensioning element 3 pushes the clamping web 5 back into the clamping position. In this clamping position, the clamping web 5 prevents unwanted adjustment of the belt 35 even in the load-free state in which the belt 35 is not under tension.

Fig. 8 zeigt den hier eingesetzten Klemmsteg 5 mit seinen einstückig angeformten federzungenartigen Vorspannelementen 3 und den Führungsstegen 17, mit denen er, vorzugsweise linear, verschiebbar im männlichen Schnallenteil 6 bzw. allgemein in der Gurtschnalle 1 gelagert ist. Fig. 8 zeigt auch den Bereich 28 des Klemmsteges zum Herumführen des Gurtes 35 um den Klemmsteg 5. Dieser Bereich 28 ist günstigerweise zwischen den Führungsstegen 17 angeordnet, wie dies in Fig. 8 auch zu sehen ist. Die Führungsstege 17 sind günstigerweise stiftartig frei auskragend ausgeführt. Auch dies ist in den Fig. 8 und 9 gut zu sehen. Durch diese randliche Anordnung der Führungsstege 17 bezüglich des Bereiches 28 wird der Gegensteg 21, in dem Bereich, in dem er mit dem Bereich 28 des Klemmstegs 5 bzw. mit dem Gurt 35 zusammenwirkt, nicht durch die Führungsstegaufnahmen 26 geschwächt. Dies ermöglicht es, in dem zum Bereich 28 korrespondierenden Bereich des Gegenstegs 21 eine relativ stabile massive Ausführung zu realisieren, ohne dass dadurch die gesamte Gurtschnalle 1 besonders dick gebaut werden muss. Fig. 8 shows the clamping bar 5 used here with its integrally formed spring tongue-like biasing elements 3 and the guide webs 17, with which he, preferably linearly, slidably mounted in the male buckle part 6 and generally in the buckle 1. Fig. 8 also shows the region 28 of the clamping web for guiding the belt 35 around the clamping web 5. This region 28 is conveniently arranged between the guide webs 17, as shown in FIG Fig. 8 can also be seen. The guide webs 17 are conveniently designed pin-like freely cantilevered. This too is in the 8 and 9 good to see. As a result of this marginal arrangement of the guide webs 17 with respect to the area 28, the counter web 21 is not weakened by the guide web receivers 26 in the area in which it interacts with the area 28 of the clamping web 5 or with the webbing 35. This makes it possible to realize a relatively stable massive version in the region of the counterpart web 21 corresponding to the region 28, without the entire belt buckle 1 having to be made particularly thick.

Fig. 9 zeigt eine Seitenansicht auf dieses einstückige Teil bestehend aus Klemmsteg 5, Vorspannelementen 3 und Führungsstegen 17. Fig. 10 zeigt einen Schnitt entlang der in Fig. 2 eingezeichneten Schnittlinie BB und damit die verschiebbare Lagerung des Klemmsteges 5 im männlichen Schnallenteil 6. In Fig. 10 ist der fertig montierte Zustand des in Form des Klemmsteges ausgeführten Befestigungsbauteils 5 gezeigt, in dem er in Richtung 32 gegen die Vorspannung der Vorspannelemente 3 und in Richtung 31 in Vorspannrichtung der Vorspannelemente 3 verschoben werden kann bzw. von der Vorspannung verschoben wird. Es handelt sich im gezeigten Ausführungsbeispiel um eine Linearverschiebung. Gut zu sehen ist in Fig. 10 auch die Anordnung eines der Führungsstege 17 in einer der Führungsstegaufnahmen 26 des Gurtbefestigungselementes 2. Gut zu sehen ist im Schnitt der Fig. 10 auch, dass die Führungsstegaufnahmen 26 in diesem Schnitt einen hier in diesem Ausführungsbeispiel keilförmig aufgeweiteten Querschnitt 27 aufweisen. Der Querschnitt 27 der Führungsstegaufnahmen 26 ist jeweils in der von der im Bereich 28 zum Herumführen des Gurtes 35 um den Klemmsteg 5 wegweisenden Richtung 31 aufgeweitet. In Fig. 9 und 10 ist darüber hinaus gut zu erkennen, dass in diesem Ausführungsbeispiel auch die Führungsstege 17, im Schnitt gesehen, jeweils einen einseitig, auch hier keilförmig aufgeweiteten Querschnitt 27 aufweisen. Der Querschnitt 27 der Führungsstege 17 ist allerdings in der zum Bereich 28 zum Herumführen des Gurtes 35 um den Klemmsteg hinweisenden Richtung 32 aufgeweitet bzw. eben in Gegenrichtung 31 verjüngt. Durch die bevorzugt keilförmig ausgeführten Querschnittsaufweitungen bzw. Verengungen der Führungsstege 17 und der Führungsstegaufnahmen 26 ist es möglich, das Befestigungsbauteil 5 in Form des Klemmsteges zur Montage an der Gurtschnalle 1 bzw. am Gurtbefestigungselement 2 auf diese bzw. dieses aufzuschwenken. Vorzugsweise rastet das Befestigungsbauteil 5 am Ende dieser Verschwenkbewegung bei der Montage in der Gurtschnalle 1 bzw. eben im Gurtbefestigungselement 2 mittels der Vorspannelemente 3 ein. Fig. 9 shows a side view of this one-piece part consisting of clamping bar 5, biasing elements 3 and guide webs 17th Fig. 10 shows a section along the in Fig. 2 Plotted section line BB and thus the displaceable mounting of the clamping bar 5 in the male buckle part 6. In Fig. 10 is the ready assembled State of the executed in the form of the clamping bar fastening member 5 shown in which it can be displaced in the direction 32 against the bias of the biasing members 3 and 31 in the biasing direction of the biasing members 3 and is displaced from the bias. It is a linear displacement in the embodiment shown. Good to see in Fig. 10 Also, the arrangement of one of the guide webs 17 in one of the guide web receivers 26 of the Gurtbefestigungselementes 2. Good to see is in section the Fig. 10 also that the guide web recordings 26 in this section have a wedge-shaped widened section 27 in this exemplary embodiment. The cross section 27 of the guide web receivers 26 is widened in each case in the direction 31 pointing away from the region 31 in the region 28 for moving the belt 35 around the clamping web 5. In FIGS. 9 and 10 is also clearly visible that in this embodiment, the guide webs 17, seen in section, each have a one-sided, widened wedge-shaped here cross-section 27. However, the cross-section 27 of the guide webs 17 is widened in the direction to the region 28 for leading the belt 35 around the clamping web direction indicating 32 or just tapers in the opposite direction 31. Due to the preferred wedge-shaped cross-sectional widening or narrowing of the guide webs 17 and the guide web receivers 26, it is possible to swivel the fastening component 5 in the form of the clamping web for mounting on the belt buckle 1 or on the belt fastening element 2 on this or this. Preferably, the fastening component 5 engages at the end of this pivoting movement during assembly in the buckle 1 or just in the Gurtbefestigungselement 2 by means of the biasing elements 3 a.

Fig. 11 zeigt eine Seitenansicht auf das hier beispielhaft dargestellte männliche Schnallenteil 6 und einen Zwischenzustand bei der Montage des Befestigungsbauteils bzw. Klemmsteges 5 mittels Aufschwenken. Fig. 12 zeigt eine Draufsicht auf diesen Zustand. Fig. 13 zeigt den Schnitt entlang der Schnittlinie DD und Fig. 14 den Schnitt entlang der Schnittlinie EE im Bereich eines Führungsstegs 17 und einer Führungsstegaufnahme 26. In Fig. 12 bis 14 ist jeweils derselbe Zwischenzustand bei der Montage wie in Fig. 11 gezeigt. In Fig. 14 zeigt der Pfeil 29 die Einschubrichtung, in der der Klemmsteg 5 mit seinen Führungsstegen 17 zunächst von schräg oben in die jeweiligen Führungsstegaufnahmen 26 des Gurtbefestigungselementes 2 bzw. männlichen Schnallenteils 6 eingeschoben wird. Der Pfeil 30 zeigt dann die Schwenkrichtung, in der das Befestigungsbauteil 5 in Form des Klemmsteges dann nach unten in die fertig montierte Stellung geschwenkt wird. Am Ende dieser Schwenkbewegung rastet das Befestigungsbauteil 5 dann mit den Vorspannelementen 3 in eine entsprechende Ausnehmung 33 ein. Damit ist dann das Befestigungsbauteil 5 mittels Aufschwenken fertig im Gurtbefestigungselement 2 bzw. in der Gurtschnalle 1 montiert, womit die in Fig. 10 dargestellte Betriebsstellung erreicht ist. Diese Montage mittels Aufschwenken wird im gezeigten Ausführungsbeispiel durch die beschriebenen, sich weitenden bzw. verjüngenden Querschnitte 27, der Führungsstegaufnahmen 26 und der Führungsstege 17 ermöglicht. Durch diese Art der Montage des Befestigungsbauteils 5 ist zur Montage weder eine Querschnittsverringerung des Klemmsteges 5 noch des Gegensteges 21 im Bereich 28, in dem der Gurt 35 angeordnet wird, notwendig, sodass diese Bauteile in diesem Bereich relativ massiv ausgeführt werden können, ohne dass hierfür eine besonders mächtige bzw. dicke Außenform der Gesamtgurtschnalle 1 gewählt werden muss. Fig. 11 shows a side view of the male buckle part 6 shown here by way of example and an intermediate state during assembly of the fastening component or clamping web 5 by pivoting. Fig. 12 shows a plan view of this state. Fig. 13 shows the section along the section line DD and Fig. 14 the section along the section line EE in the region of a guide web 17 and a guide bar recording 26. In Fig. 12 to 14 is in each case the same intermediate state during assembly as in Fig. 11 shown. In Fig. 14 shows the arrow 29, the insertion direction in which the clamping web 5 with its guide webs 17 initially obliquely from above in the respective guide web receivers 26 of the Gurtbefestigungselementes 2 and male buckle part 6 is inserted. The arrow 30 then shows the pivoting direction, in which the fastening component 5 in the form of the clamping web is then pivoted downwards into the fully assembled position. At the end of this pivoting movement, the fastening component 5 then engages with the biasing elements 3 in a corresponding recess 33 a. Thus, then the fastening member 5 is completed by pivoting in the belt fastening element 2 and mounted in the buckle 1, whereby the in Fig. 10 shown operating position is reached. This assembly by pivoting is in the illustrated embodiment by the described, widening or tapered cross-sections 27, the guide web receivers 26 and the guide webs 17 allows. As a result of this type of mounting of the fastening component 5, neither a cross-sectional reduction of the clamping web 5 nor of the counterpart web 21 in the region 28 in which the belt 35 is arranged is necessary for assembly, so that these components can be made relatively solid in this region without this being necessary a particularly powerful or thick outer shape of the overall belt buckle 1 must be selected.

Fig. 14a zeigt einen Längsschnitt durch das auch in Fig.11 dargestellte männliche Schnallenteil 6. Allerdings ist das als Klemmsteg ausgeführte Befestigungsbauteil 5 in Fig. 14a fertig montiert. Weiters ist in Fig. 14a auch der um den Klemmsteg 5 im Bereich 28 und dem dazu korrespondierenden Bereich des Gegenstegs 21 gewickelte Gurt 35 dargestellt. In Fig. 14a ist eine Betriebsstellung gezeigt, in der in Richtung Fz am Gurt 35 gezogen wird und Klemmsteg 5 und Gegensteg 21 den Gurt 35 durch ihr Zusammenwirken festklemmen. Fig. 14a shows a longitudinal section through that also in Figure 11 Male buckle part 6 shown, however, is executed as a clamping web fastening component 5 in Fig. 14a fully assembled. Furthermore is in Fig. 14a also the belt 35 wound around the clamping web 5 in the region 28 and the corresponding region of the counter web 21 is shown. In Fig. 14a is shown an operating position in which is pulled in the direction F z on the belt 35 and clamping web 5 and the web 21 clamp the belt 35 by their interaction.

Bei entsprechend starkem Zug Fz wirken auf den Klemmsteg 5 die Kräfte F1 und D4 und auf den Gegensteg 21 die Kräfte F2 und F3, wie sie in Fig. 14a eingezeichnet sind. All diese Kräfte F1 bis F4 können ab einem gewissen Betrag eine Deformation von Klemmsteg 5 und Gegensteg 21 bewirken, welche ab einem gewissen Grad der Deformation zu einer Lockerung oder zu einem Versagen der Klemmung des Gurtes 35 durch das Zusammenwirken von Klemmsteg 5 und Gegensteg 21 führen könnte. Um dem entgegen zu wirken bzw. dies zu vermeiden, sehen bevorzugte Ausführungsbeispiele der Erfindung, wie das hier gezeigte Ausführungsbeispiel vor, dass durch die Möglichkeit der Montage mittels des oben geschilderten seitlichen Aufschwenkens des Klemmsteges 5 auf das Schnallenteil 6 sowohl Klemmsteg bzw. Befestigungsbauteil 5 als auch Gegensteg 21 recht massiv ausgebildet werden können, ohne dass dies zu einer besonders mächtigen Außenform der Gurtschnalle 1 führt.In accordance with strong train F z act on the clamping bar 5, the forces F 1 and D 4 and the counterpart web 21, the forces F 2 and F 3 , as in Fig. 14a are drawn. All these forces F 1 to F 4 can cause a deformation of the clamping web 5 and the counterpart web 21 above a certain amount, which from a certain degree of deformation to a loosening or failure of the clamping of the belt 35 by the interaction of clamping web 5 and counterpart web 21 could lead. To counteract this or to avoid this, see preferred embodiments The invention, as the embodiment shown here, that by the possibility of mounting by means of the above-described lateral pivoting of the clamping web 5 on the buckle part 6 both clamping web or fastening member 5 and the web 21 can be quite massively formed without this to a particularly powerful outer shape of the buckle 1 leads.

Wie in Fig. 14a beispielhaft gezeigt, kann bei bevorzugten Ausführungsbeispielen der Erfindung in diesem Sinne aber auch vorgesehen sein, dass der Klemmsteg bzw. das Befestigungsbauteil 5 und der damit zur Klemmung des Gurtes 35 zusammenwirkende Gegensteg 21 zumindest in der Klemmstellung, in der sie den Gurt 35 festklemmen, versetzt zueinander angeordnet sind. Günstigerweise sind der Klemmsteg bzw. das Befestigungsbauteil 5 und der Gegensteg 21 dabei in einer Richtung 36 orthogonal zur Trennrichtung 25 versetzt zueinander angeordnet. Der Klemmsteg 5 ist dabei besonders bevorzugt in einer Richtung 36 gegen den Gegensteg 21 versetzt, welche von dem Bereich, in dem der Gurt 35 am Gegensteg 21 anliegt, weg weist. Der Zug Fz wirkt in der Regel in einer Richtung parallel zur Trennrichtung 25. Durch diesen, in Fig. 14a gezeigten Versatz wird jedenfalls erreicht, dass es durch Deformation des Klemmsteges 5 in Richtung der Kraft F, und Deformation des Gegensteges 21 in Richtung der Kraft F2 nicht so schnell zu einem Lösen der Klemmung des Gurtes 35 kommen kann, wodurch ebenfalls die Belastbarkeit der Schnalle erhöht wird, ohne dass dazu ihre Außenmaße vergrößert werden müssen.As in Fig. 14a By way of example, in preferred embodiments of the invention it can also be provided in this sense that the clamping web or fastening component 5 and the counter web 21 cooperating therewith for clamping the belt 35 are displaced at least in the clamping position in which they clamp the belt 35 are arranged to each other. Conveniently, the clamping web or the fastening component 5 and the counterpart web 21 are arranged in a direction 36 orthogonal to the separating direction 25 offset from one another. The clamping web 5 is particularly preferably offset in a direction 36 against the counter-web 21, which points away from the region in which the belt 35 abuts against the web 21. The train F z usually acts in a direction parallel to the separating direction 25. Through this, in Fig. 14a shown offset is achieved in any case, that it can not come so quickly to a loosening of the clamping of the belt 35 by deformation of the clamping bar 5 in the direction of the force F, and deformation of the counter bar 21 in the direction of the force F 2 , whereby also the load capacity of the buckle without having to increase its external dimensions.

Um das männliche Schnallenteil 6 nur in einer einzigen Stellung in das weibliche Schnallenteil 7 einstecken zu können, sind in den Ausführungsbeispielen der Gurtschnallen 1 gemäß der Fig. 1 bis 17 und 19 bis 26 unterschiedlich ausgebildete Anformungen und entsprechende Gegenausnehmungen an den weiblichen und männlichen Schnallenteilen 7 und 6 realisiert, welche zusammen eine Einsteckindizierung 19 bilden, indem sie sicherstellen, dass das männliche Schnallenteil 6 nur in einer einzigen Stellung in das weibliche Schnallenteil 7 eingeführt bzw. eingeschoben werden kann.In order to insert the male buckle part 6 only in a single position in the female buckle part 7, are in the embodiments of the buckles 1 according to the Fig. 1 to 17 and 19 to 26 realized differently shaped projections and corresponding counter-recesses on the female and male buckle parts 7 and 6, which together form a Einsteckindizierung 19 by ensuring that the male buckle part 6 can be inserted or inserted only in a single position in the female buckle part 7.

In der in den Fig. 1 und 2 gezeigten Verriegelungsstellung verriegeln die als Verriegelungshebel ausgebildeten Befestigungsbauteile 4 das männliche Schnallenteil 6 im weiblichen Schnallenteil 7. Hierzu weist der Einschubanker 14 Verriegelungsschultern 15 auf, welche in der vollständig eingeschobenen Position des männlichen Schnallenteils 6 in das weibliche Schnallenteil 7 von den Verriegelungshebeln 4 hintergriffen werden. Die hier ebenfalls einstückig angeformten und als Federzungen ausgebildeten Vorspannelemente 3 drücken die als Verriegelungshebel ausgebildeten anderen Befestigungsbauteile 4 in die Verriegelungsstellung. Zieht man nun in der Verriegelungsstellung der Verriegelungshebel an einem oder beiden der Schnallenteile 6 und/oder 7 in einer der oder beiden Trennrichtungen 25 bzw. 34, wie sie in den Fig. 1 und 5 eingezeichnet sind, so werden die Verriegelungshebel 4 in diesen Ausführungsbeispielen ausschließlich auf Druck belastet. Hierdurch können die Verriegelungshebel 4 auch bei einer realtiv schlanken Bauweise relativ hohe Kräfte aufnehmen und somit für eine sichere Verriegelung sorgen. Diese Belastung auf Druck wird im gezeigten Ausführungsbeispiel dadurch erreicht, dass die Verriegelungsschulter 15 und die Schwenkachsen 8, um die die Befestigungsbauteile bzw. Verriegelungshebel 4 schwenkbar gelagert sind, so angeordnet sind, dass die Verriegelungsschultern 15 beim Trennen des männlichen Schnallenteils vom weiblichen Schnallenteil 7 jeweils an der jeweiligen Schwenkachse 8 vorbei zu bewegen sind.In the in the Fig. 1 and 2 For this purpose, the insertion anchor 14 locking shoulders 15, which are engaged behind in the fully inserted position of the male buckle part 6 in the female buckle part 7 of the locking levers 4. The biasing elements 3, which are also integrally formed here and designed as spring tongues, press the other fastening components 4 designed as locking levers into the locking position. Now draws in the locking position of the locking lever on one or both of the buckle parts 6 and / or 7 in one or both separating directions 25 and 34, as shown in the Fig. 1 and 5 are drawn, the locking lever 4 are charged in these embodiments exclusively to pressure. As a result, the locking lever 4 can absorb relatively high forces even with a relatively slim design and thus ensure a secure locking. This load on pressure is achieved in the illustrated embodiment in that the locking shoulder 15 and the pivot axes 8, about which the fastening components or locking lever 4 are pivotally mounted, are arranged so that the locking shoulders 15 when separating the male buckle part from the female buckle part 7 respectively are to be moved past the respective pivot axis 8 over.

Fig. 3 zeigt eine Seitenansicht auf die Gurtschnalle 1 gemäß Fig. 1 und 2 und die Schnittlinie CC. Die Fig. 4 und 5 zeigen Schnitte in einer in Fig. 3 durch die Schnittlinie CC gekennzeichneten Schnittebene durch die Gurtschnalle 1. In Fig. 4 befindet sich der Einschubanker 14 und damit das männliche Schnallenteil 6 in der Verriegelungsstellung. In dieser hintergreifen die beiden Verriegelungshebel 4 die Verriegelungsschulter 15 des Einschubankers 14, sodass das männliche Schnallenteil 6 nicht aus dem weiblichen Schnallenteil 7 herausgezogen werden kann. Die hier ebenfalls als Federzungen ausgebildeten Vorspannelemente 3 spannen die Befestigungsbauteile 4 in Richtung dieser Verriegelungsstellung vor. Fig. 3 shows a side view of the buckle 1 according to Fig. 1 and 2 and the cutting line CC. The 4 and 5 show cuts in an in Fig. 3 Section plane indicated by the section line CC through the buckle 1. In Fig. 4 is the insertion anchor 14 and thus the male buckle part 6 in the locked position. In this, the two locking lever 4 engage behind the locking shoulder 15 of the insertion anchor 14, so that the male buckle part 6 can not be pulled out of the female buckle part 7. The biasing elements 3, which are also designed as spring tongues, clamp the fastening components 4 in the direction of this locking position.

Um das männliche Schnallenteil 6 aus dem weiblichen Schnallenteil 7 herausziehen zu können, muss im Zwischenbereich 22 zwischen den Gehäusen des männlichen und des weiblichen Schnallenteils 6 und 7 auf die dort hervorstehenden Bereiche der Befestigungsbauteile 4 gedrückt werden. Dies kann man z.B. mit zwei Fingern tun. Hierdurch werden die Befestigungsbauteile 4 um ihre Schwenkachsen 8 gegen die Vorspannung der Vorspannelemente 3 so weit verschwenkt, bis die Verriegelungsschultern 15 des Einschubankers 14 freikommen. Diese Stellung ist in Fig. 5 gezeigt. Bevorzugte Ausgestaltungsformen der Erfindung sehen dabei vor, dass die Außenkontur des männlichen Schnallenteils 6 im Bereich der anderen Befestigungsbauteile 4 so mit der Außenkontur der anderen Befestigungsbauteile 4 abgestimmt ist, dass beim Verschwenken der anderen Befestigungsbauteile 4 in ihre Freigabestellung gemäß Fig. 5 das männliche Schnallenteil 6 automatisch zumindest ein Stück weit in seiner Trennrichtung 25 aus der Aufnahmeausnehmung 18 des weiblichen Schnallenteils 7 herausgeschoben wird. Hierdurch wird verhindert, dass beim Loslassen der Befestigungsbauteile 4 diese von alleine wieder hinter den Verriegelungsschultern 15 einrasten. Im gezeigten Ausführungsbeispiel ist, wie auch sonst bevorzugt, vorgesehen, dass sich die beiden Schnallenteile 6 und 7 in ihren jeweiligen Trennrichtungen 25 und 34 nur dann voneinander trennen lassen, wenn alle, hier die beiden, anderen Befestigungsbauteile 4 den Einschubanker 14 freigeben. Werden versehentlich nicht alle anderen Befestigungsbauteile 4 so weit gedrückt, dass sie den Einschubanker 14 bzw. dessen Verriegelungsschultern 15 freigeben, so verhindern das oder die verbleibenden anderen Befestigungsbauteile 4 eine vollständige Entriegelung, sodass die Schnallenbauteile 6 und 7 dann nicht getrennt werden können.In order to pull the male buckle part 6 out of the female buckle part 7, in the intermediate region 22 between the housings of the male and the female buckle part 6 and 7 are pressed onto the there protruding portions of the fastening components 4. This can be done with two fingers, for example. As a result, the fastening components 4 are pivoted about their pivot axes 8 against the bias of the biasing members 3 so far until the locking shoulders 15 of the insertion anchor 14 free. This position is in Fig. 5 shown. Preferred embodiments of the invention provide that the outer contour of the male buckle part 6 in the region of the other fastening components 4 is matched with the outer contour of the other fastening components 4 such that upon pivoting of the other fastening components 4 in their release position Fig. 5 the male buckle part 6 is automatically pushed out of the receiving recess 18 of the female buckle part 7 at least a little bit in its separating direction 25. This prevents that when releasing the fastening components 4, these lock themselves behind the locking shoulders 15 again. In the embodiment shown, as well as otherwise preferred, provided that the two buckle parts 6 and 7 in their respective separation directions 25 and 34 can only be separated from each other when all, here the two, other fastening components 4 release the insertion anchor 14. If not all other fastening components 4 are inadvertently pressed so far that they release the insertion anchor 14 or its locking shoulders 15, then the remaining fastening components 4 or 4 prevent complete unlocking, so that the buckle components 6 and 7 can not then be separated.

Fig. 17 zeigt eine Ansicht auf die vollständig voneinander getrennten männlichen und weiblichen Schnallenteile 6 und 7 der Gurtschnalle 1 des ersten Ausführungsbeispiels. Fig. 17 shows a view of the completely separate male and female buckle parts 6 and 7 of the buckle 1 of the first embodiment.

Fig. 6 zeigt einen Schnitt durch das weibliche und das männliche Schnallenteil 7 und 6 im miteinander verriegelten Zustand entlang der in Fig. 2 eingezeichneten Schnittlinie AA. Hier ist besonders gut der Bereich zu sehen, in dem die beiden anderen Befestigungsbauteile 4 um ihre jeweiligen Schwenkachsen 8 schwenkbar mittels der Achsbolzen 9 gelagert sind. Fig. 6 shows a section through the female and the male buckle part 7 and 6 in the locked state along the in Fig. 2 drawn section line AA. Here is particularly well to see the area in which the two other fastening components 4 are mounted about their respective pivot axes 8 pivotally by means of the axle 9.

Die in diesem ersten Ausführungsbeispiel verwendeten Achsbolzen 9 sind in zwei alternativen Ausführungsformen in Fig. 15 und 16 noch einmal vergrößert dargestellt. Sie weisen in beiden Varianten jeweils eine Aufnahmeausnehmung 11 auf, in die ein Einführteil 10 eingebracht werden kann bzw. in den Fig. auch eingebracht ist. Bei diesen Ausführungsbeispielen tragen sowohl der Achsbolzen 9 als auch das jeweilige Einführteil 10 Köpfe 12 und 13. Zwischen dem Kopf 12 des Achsbolzens 9 und dem Kopf 13 des Einführteils 10 ist der gesamte Achsbolzen 9 am weiblichen Schnallenteil 7 gehalten. Beim Einführteil 10 kann es sich, wie in Fig. 15 gezeigt, um eine Schraube handeln. Alternativ sind aber auch andere Ausgestaltungsformen, wie z.B. in Fig. 16 gezeigt, möglich. Hier handelt es sich beim Einführteil 10 um eine Niete. Durch das Einfügen des Einführteils 10 in die jeweilige Ausnehmung 11 des Achsbolzens 9 wird letztere ein wenig aufgespannt, sodass der jeweilige Achsbolzen 9 sicher in der jeweiligen Achsbolzenaufnahme 16 des weiblichen Schnallenteils 7 gehalten wird. Die Befestigung der Achsbolzen 9 in den Achsbolzenaufnahmen 16 kann aber auch rein mittels der Köpfe 12 und 13 erfolgen, wenn das Einführteil 10, z.B. mittels Reib- und/oder Formschluss, entsprechend fest im Achsbolzen 9 befestigt ist. Fig. 16a zeigt noch ein Beispiel eines alternativ verwendbaren Achsbolzens 9. Dieser ist einteilig bzw. einstückig ausgeführt. Im gezeigten Ausführungsbeispiel trägt er Federzungen 23 mit Rastvorsprüngen 24. Mittels der Rastvorsprünge 24 rastet dieser Achsbolzen 9 bei vollständigem Einschieben in die Achsbolzenaufnahme 16 ein, sodass der Achsbolzen 9 mittels seines Kopfes 12 und seiner Rastvorsprünge 24 in der Achsbolzenaufnahme 16 verankert ist. Eine weitere, hier nicht dargestellte Alternative besteht in einem nietartigen einstückigen Achsbolzen 9 ohne Federzungen 23 und Rastvorsprüngen 24.The axle pin 9 used in this first embodiment are in two alternative embodiments in FIGS. 15 and 16 shown enlarged again. In both variants, they each have a receiving recess 11 into which an insertion part 10 can be introduced or is also introduced into the FIG. In these embodiments, both the axle pin 9 and the respective insertion part 10 carry heads 12 and 13. Between the head 12 of the axle pin 9 and the head 13 of the insertion part 10 of the entire axle 9 is held on the female buckle part 7. When insertion 10, it may, as in Fig. 15 shown to act a screw. Alternatively, however, are other embodiments, such as in Fig. 16 shown, possible. Here it is the insertion part 10 is a rivet. By inserting the insertion part 10 into the respective recess 11 of the axle pin 9, the latter is spanned a little so that the respective axle pin 9 is held securely in the respective axle pin receptacle 16 of the female buckle part 7. The attachment of the axle 9 in the Achsbolzenaufnahmen 16 but can also be done purely by means of the heads 12 and 13, when the insertion part 10, for example by means of frictional and / or positive locking, fixed according fixed in the axle 9. Fig. 16a shows yet another example of an alternative usable axle pin 9. This is made in one piece or in one piece. In the illustrated embodiment, it carries spring tongues 23 with latching projections 24. By means of the latching projections 24 engages this axle pin 9 when fully inserted into the Achsbolzenaufnahme 16, so that the axle 9 is anchored by means of its head 12 and its locking projections 24 in the Achsbolzenaufnahme 16. Another, not shown here alternative consists in a rivet-like one-piece axle pin 9 without spring tongues 23 and locking projections 24th

Fig. 7 zeigt, losgelöst von den anderen Bauteilen der Gurtschnalle 1, das als Verriegelungshebel verwendete andere Befestigungsbauteil 4, an dem erfindungsgemäß einstückig das Vorspannelement 3 angeordnet ist. Auch hier ist das Vorspannelement 3 als flexible Federzunge ausgebildet. Im Befestigungsbauteil 4 ist noch die Achsbolzenaufnahme 16 eingezeichnet, durch die der Achsbolzen 9 hindurchgeführt werden kann. Fig. 7 shows, detached from the other components of the buckle 1, the other fastening component used as a locking lever 4, on which according to the invention integrally the biasing member 3 is arranged. Again, the biasing member 3 is formed as a flexible spring tongue. In the fastening component 4 is still the Achsbolzenaufnahme 16 located through which the axle 9 can be passed.

Grundsätzlich ist es denkbar, die Gurtschnalle 1 des ersten Ausführungsbeispiels wie auch aller anderen hier gezeigten Ausführungsbeispiele, wie meist üblich, aus Metall auszuführen. Besonders bevorzugte Ausgestaltungsformen der Erfindung sehen aber vor, dass es sich um eine sogenannte Kunststoffschnalle handelt. Hierbei kann die gesamte Gurtschnalle 1 aus Kunststoff hergestellt sein. Insbesondere ist es aber günstig, Vorspannelement 3 und Befestigungsbauteil 4 bzw. 5, wie sie in den Fig. 7, 8 und 9 separat gezeigt sind, einstückig als Kunststoffteil herzustellen. Der Spritzguss stellt hier ein kostengünstiges Verfahren zur Herstellung der Teile dar.Basically, it is conceivable, the buckle 1 of the first embodiment as well as all other embodiments shown here, as usually usual, made of metal. However, particularly preferred embodiments of the invention provide that it is a so-called plastic buckle. Here, the entire buckle 1 may be made of plastic. In particular, it is favorable, biasing element 3 and fastening component 4 and 5, as in the Fig. 7 . 8 and 9 are shown separately, in one piece as a plastic part. Injection molding here represents a cost-effective method for producing the parts.

Fig. 18 zeigt beispielhaft in einem zweiten Ausführungsbeispiel der Erfindung, dass die Gurtschnalle 1 auch einen einstückigen Grundkörper aufweisen kann, also nicht unbedingt zwei Schnallenteile 6 und 7, welche lösbar miteinander verbunden werden können, aufweisen muss. Der in Fig. 18 gezeigte Grundkörper der Gurtschnalle 1 verbindet die beiden Gurtbefestigungselemente 2 dieses zweiten Ausführungsbeispiels gemäß Fig. 18 einstückig. In beiden Gurtbefestigungselementen 2 sind erfindungsgemäße Befestigungsbauteile 5 in Form von Klemmstegen zum daran befestigen von Gurten 35 bzw. Bändern vorgesehen. Diese Befestigungsbauteile 5 des zweiten Ausführungsbeispiels mit ihren Vorspannelementen 3 sind wie beim ersten Ausführungsbeispiel ausgeführt und müssen daher nicht noch einmal näher erläutert werden. Die Variante gemäß Fig. 18 erlaubt es, zwei verschieden breite Gurte 35 bzw. Bänder verstellbar miteinander zu verbinden. Fig. 18 shows by way of example in a second embodiment of the invention that the buckle 1 may also have a one-piece body, so not necessarily two buckle parts 6 and 7, which can be releasably connected to each other, must have. The in Fig. 18 shown main body of the buckle 1 connects the two Gurtbefestigungselemente 2 of this second embodiment according to Fig. 18 integrally. In both Gurtbefestigungselementen 2 fastening members 5 according to the invention in the form of clamping webs for attaching thereto straps 35 and ribbons are provided. These fastening components 5 of the second embodiment with their biasing elements 3 are designed as in the first embodiment and therefore need not be explained again. The variant according to Fig. 18 allows to connect two different width straps 35 or bands adjustable with each other.

In den Fig. 19 bis 26 sind weitere erfindungsgemäße Ausführungsbeispiele von Gurtschnallen 1 gezeigt. Das besondere hieran ist, neben den erfindungsgemäß ausgebildeten Befestigungsbauteilen 5, dass die männlichen Schnallenteile 6 eines jeden dieser Ausführungsbeispiele mit jedem weiblichen Schnallenteil 7 der anderen Ausführungsbeispiele kombiniert werden kann. Z.B. bilden die Ausgestaltungsformen gemäß der Fig. 19 und 20 ein Set mit einem männlichen Schnallenteil 6 und zwei weiblichen Schnallenteilen 7, wobei die weiblichen Schnallenteile 7 voneinander verschieden breite Gurtbefestigungselemente 2 für voneinander verschieden breite Gurte 35 aufweisen und mit dem männlichen Schnallenteil 6 verriegelbar sind.In the FIGS. 19 to 26 Further embodiments of the invention of buckles 1 are shown. The special feature of this, in addition to the inventively designed fastening components 5, that the male buckle parts 6 of each of these embodiments with each female buckle part 7 of the other embodiments can be combined. For example, the embodiments according to the FIGS. 19 and 20 a set with a male buckle part 6 and two female buckle parts 7, wherein the female buckle parts 7 from each other differently wide Gurtbefestigungselemente 2 have different widths of belts 35 and lockable with the male buckle part 6.

Das gleiche gilt auch, nur um ein weiteres Beispiel herauszugreifen, für die Ausführungsvarianten gemäß der Fig. 21 und 22. Nimmt man die Ausführungsvarianten gemäß der Fig. 19 und 21 zusammen, so liegt hier ein Set mit einem weiblichen Schnallenteil 7 und zwei männlichen Schnallenteilen 6 vor, wobei die männlichen Schnallenteile 6 voneinander verschieden breite Gurtbefestigungselemente 2 für voneinander verschieden breite Gurte 35 aufweisen und im oder am weiblichen Schnallenteil 6 verriegelbar sind. Ein solches Set wird auch von den, in den Fig. 20 und 22 gezeigten Gurtschnallen 1 gebildet. Dabei ist klar, dass entsprechende Sets letztendlich aus beliebig vielen männlichen und weiblichen Schnallenteilen 6 und 7 bestehen können, solange zumindest ein für die männlichen Schnallenteile 6 passendes weibliches Schnallenteil 7 und umgekehrt vorhanden ist. Legende zu den Hinweisziffern: 1 Gurtschnalle 30 Schwenkrichtung 2 Gurtbefestigungselement 31 Richtung 3 Vorspannelement 32 Richtung 4 anderes Befestigungsbauteil 33 Aufnahme 5 Befestigungsbauteil 34 Trennrichtung 6 männliches Schnallenteil 35 Gurt 7 weibliches Schnallenteil 36 Richtung 8 Schwenkachse 9 Achsbolzen 10 Einführteil 11 Ausnehmung 12 Kopf 13 Kopf 14 Einschubanker 15 Verriegelungsschulter 16 Achsbolzenaufnahme 17 Führungssteg 18 Aufnahmeausnehmung 19 Einsteckindizierung 20 Steg 21 Gegensteg 22 Zwischenfreiraum 23 Federzunge 24 Rastvorsprung 25 Trennrichtung 26 Führungsstegaufnahme 27 Querschnitt 28 Bereich 29 Einschubrichtung The same is true, just to pick another example, for the embodiments according to the FIGS. 21 and 22 , Taking the variants according to the FIGS. 19 and 21 together, so here is a set with a female buckle part 7 and two male buckle parts 6, wherein the male buckle parts 6 mutually different width Gurtbefestigungselemente 2 have different widths of belts 35 and lockable in or on the female buckle part 6. Such a set is also used by those in the FIGS. 20 and 22 Belt buckles 1 shown formed. It is clear that corresponding sets may ultimately consist of any number of male and female buckle parts 6 and 7, as long as at least one of the male buckle parts 6 matching female buckle part 7 and vice versa is available. <b> legend </ b> to the reference numbers: 1 buckle 30 pan direction 2 strap fastener 31 direction 3 biasing member 32 direction 4 other fastening component 33 admission 5 attachment member 34 separating direction 6 male buckle part 35 belt 7 female buckle part 36 direction 8th swivel axis 9 axle 10 insertion 11 recess 12 head 13 head 14 insert anchors 15 locking shoulder 16 Achsbolzenaufnahme 17 guide web 18 receiving recess 19 Einsteckindizierung 20 web 21 against Steg 22 Between freedom 23 spring tongue 24 catch projection 25 separating direction 26 Guide web recording 27 cross-section 28 Area 29 insertion direction
