Description

buckle

The present invention relates to a buckle with at least one Gurtbefestigungselement for at least one belt and at least one, biased by at least one resilient biasing member fastening member. Generic buckles are e.g. from AT 506 214 B1 and EP 2 191

739 A2 known. The first Austrian patent discloses a two-piece buckle with a male buckle and a female buckle. In the locking position, the male buckle part is locked in the female buckle part by means of fastening components designed as locking levers. As elastic biasing elements are coil springs, which bias the locking lever in the direction of its locking position.

The second European application shows both buckles with a male and a female buckle part as well as buckles consisting of a single buckle part. In Figs. 9 to 13 of this European application, a fastening member designed as a clamping web for clamping a belt is known, which is biased by, formed in the form of coil springs, elastic biasing elements in the direction of its clamping position.

The object of the invention is to simplify the construction of generic buckles.

For this purpose, it is provided that the biasing element is integrally formed on the fastening component. In other words, it is thus provided according to the invention that the biasing element and the locking element are made continuously as a part.

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.

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.

In principle, various types of biasing elements may be provided integrally with various types of fastening components of the buckle according to the invention. 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.

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. For example, it may be buckles of metal and plastic or even pure metal buckles. 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 belt buckle and the Gurtbefesti- supply element can be designed very different. It may be buckles, which are constructed in two or more parts, wherein a first part of the buckle, a first Gurtbefestigungselement for a first strap and at least one further buckle part has at least one further belt fastening element for at least one further belt, wherein the buckle parts can be releasably fastened to one another or can be locked together. In such embodiments, the one or more fastening components may be formed as a locking lever, with which the buckle parts are releasably fastened to one another or lockable.

Particularly preferred embodiments provide that the belt 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 are separable from one another and lockable to each other or to each other by means of the fastening element designed as a locking lever or at least one of the fastening components designed as a locking lever , 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, of the locking lever formed as fastening components in the locked position in which the male Buckle part and the female buckle part are interlocked or locked to each other 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 loaded on 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 be provided, for example, that at least one, preferably each, of the locking lever formed as 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 to each other, a locking shoulder of a Einschuban - engages behind the male buckle part, wherein the locking shoulder is to move when separating the male buckle part of the female buckle part on the pivot axis over. This ensures that the locking lever is loaded only on pressure when he is in the locking position and is pulled on at least one of the buckle parts in the respective separation direction.

However, the invention can also be implemented in belt buckles which consist only of a buckle part, preferably with one or more belt fastening elements.

It is also possible for the fastening component or at least one of the fastening components to be a clamping web, preferably forming part of the belt fastening element, for clamping the belt guided around the clamping web.

In order to achieve high strength of the belt fastening element here as well as possible with slender elements, preferred embodiments of the belt buckle according to the invention provide that the fastening component or at least one of the fastening components for mounting on the belt buckle can be pivoted onto the belt buckle, preferably latching in the belt buckle , A corresponding method for mounting such a fastening component provides that the fastening component or at least one of the fastening components for mounting on the buckle on this, preferably latching in the buckle, is pivoted.

Thus, it is possible, for example, for the fastening component to have guide webs with which it is mounted, preferably linearly displaceable, in guide web receptacles of the belt fastening element, wherein the guide web receptacles and / or the guide webs, viewed in a section, each have a one-sided, preferably wedge-shaped, have expanded cross-section. The widened cross section of the guide web receptacles and / or guide webs allows the pivoting movement during Swinging the fastening component designed as a clamping web. It is particularly favorable if the widened cross-section is wedge-shaped.

Due to the possibility of mounting the fastening component designed as a clamping web on the belt buckle by pivoting, both the clamping web itself and the counter web of the belt fastening element cooperating with it can be made relatively solid and strong, without this being equal to a particularly powerful or thick design the entire buckle leads. 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.

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 guide web receptacles are then conveniently arranged so that the counterpart web is not weakened by the guide web recordings in the region in which it interacts with the webbing and the clamping web. 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.

The fastening component is usually mounted movably in some form. Preferred embodiments provide in this context that Tigungsbauteil, preferably linearly, slidably and / or pivotally mounted. The biasing member may be provided to bias the fastening member toward its clamping position or its locking position.

When the fastening member is pivotally mounted about a pivot axis, preferred embodiments of the invention provide that the pivot axis has at least one outer axle and at least one inner, preferably designed as a pin or screw, insertion part, wherein the insertion part inserted into a recess in the axle bolt or 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.

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, if 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 have strap fasteners of different widths to one another 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. 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 shows a second embodiment of a buckle according to the invention;

Fig. 19 to 26 further exemplified selected embodiments of buckles according to the invention.

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 Figs. 1 and 2, the male buckle member 6 is fully 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 lock lever designed according to the invention formed fastening components 4, so that the male buckle part 6 is not out of the female buckle part 7 can be pulled out. 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 visible in Fig. 1, 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 not shown belt 35 from

Clamping web 5 is pressed 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 shows the clamping web 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. 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 can also be seen in FIG. 8. The guide webs 17 are conveniently designed pin-like freely cantilevered. This is also clearly visible in FIGS. 8 and 9. 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 shows a side view of this one-piece part consisting of clamping web 5, biasing elements 3 and guide webs 17. Fig. 10 shows a section along the drawn in Fig. 2 section line BB and thus the displaceable mounting of the clamping web 5 in the male buckle part 6. In Fig. 10 is the finished 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. In the exemplary embodiment shown, this is a linear displacement. The arrangement of one of the guide webs 17 in one of the guide web receivers 26 of the belt fastening element 2 can also be clearly seen in FIG. 10. It can also be clearly seen in the section of FIG. 10 that the guide web receivers 26 in this section have widened wedge-shaped in this exemplary embodiment Cross section 27 have. 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 addition, FIGS. 9 and 10 clearly show that, in this exemplary embodiment, the guide webs 17, when viewed in section, each have a cross-section 27 which is widened in a wedge-shaped manner on one side. However, the cross section 27 of the guide webs 17 is widened in the direction 32 pointing toward the region 28 for leading the belt 35 around the clamping web or, in the opposite direction 31, is tapered. 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. 1 1 shows a side view of the male exemplified here

Buckle part 6 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. 13 shows the section along the section line DD, and FIG. 14 shows the section along the section line EE in the region of a guide web 17 and a guide web receiver 26. In FIGS. 12 to 14, the same intermediate state is in each case during assembly as in FIG. 1 1 shown. In Fig. 14, the arrow 29 shows the insertion direction in which the clamping web 5 with its guide webs 17 initially obliquely from above into 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 pretensioning elements 3 in a corresponding recess 33. Thus, then the fastening component 5 is finished by pivoting ready in the Gurtbefestigungselement 2 or in the buckle 1, whereby the operating position shown in Fig. 10 is reached. This mounting 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 shows a longitudinal section through the male buckle part 6 also shown in FIG. 1. However, the fastening component 5 designed as a clamping web is completely assembled in FIG. 14a. Furthermore, in Fig. 14a also around the clamping web 5 in

Region 28 and the corresponding region corresponding to the web 21 wound belt 35 shown. In Fig. 14a, an operating position is shown in which in the direction F _{z is} pulled on the belt 35 and clamping web 5 and the web 21 clamp the belt 35 by their interaction.

In accordance with strong train F _z act on the clamping bar 5, the forces F, and F ₄ and on the opposite web 21, the forces F ₂ and F ₃ , as shown in Fig. 14a. All these forces F, to F ₄ can cause from a certain amount, a deformation of the clamping web 5 and the counterpart web 21, 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. In order to counteract or avoid this, preferred embodiments Examples of embodiments of 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 21 counterstay can be quite massively formed without this a particularly powerful outer shape of the buckle 1 leads.

As shown by way of example in FIG. 14 a, in preferred embodiments of the invention it can also be provided in this sense that the clamping web or the fastening component 5 and the counter web 21 cooperating therewith for clamping the belt 35 at least in the clamping position in which they clamp the belt 35, offset from one another. 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. In this case, the clamping web 5 is particularly preferably offset in one direction 36 against the counter web 21, which points away from the region in which the belt 35 rests against the counter web 21. The train F _z usually acts in a direction parallel to the separating direction 25. By this, shown in Fig. 14a offset is achieved in any case that it by deformation of the clamping bar 5 in the direction of the force F, and deformation of the counter-web 21 in the direction of Force F ₂ can not come so quickly to a release of the clamping of the belt 35, which also increases the load capacity of the buckle, without having to increase their external dimensions.

In order to be able to insert the male buckle part 6 into the female buckle part 7 only in a single position, in the exemplary embodiments of the buckles 1 according to FIGS. 1 to 17 and 19 to 26 differently shaped projections and corresponding counter-recesses on the female and male Implemented 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 the locking position shown in FIGS. 1 and 2, the fastening components 4 designed as locking levers lock the male buckle part 6 in the female buckle part 7. For this purpose, the insertion anchor 14 has locking shoulders 15, which in the fully inserted position of the male buckle part 6 into the female buckle part 7 are engaged behind by the locking levers 4. The here also integrally formed and designed as a spring tongues biasing elements 3 press the locking elements formed as fastening components 4 in the locked 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

1 and 5 are shown, 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 shows a side view of the buckle 1 according to FIGS. 1 and 2 and the section line CC. FIGS. 4 and 5 show sections through the belt buckle 1 in a sectional plane indicated by the section line CC in FIG. 3. In Fig. 4 is the insertion anchor 14 and thus the male buckle part 6 in the locking 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.

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 elements 3 until the locking shoulders 15 of the insertion anchor 14 are released. This position is shown in Fig. 5. Preferred embodiments of the invention provide in this case that the outer contour of the male buckle part 6 in the region of the fastening components 4 is matched to the outer contour of the fastening components 4, that when pivoting the fastening components 4 in their release position shown in FIG. 5, the male buckle part 6 automatically at least one Piece is far pushed out in its separating direction 25 from the receiving recess 18 of the female buckle part 7. 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 can only be separated from each other in their respective separation directions 25 and 34, when all, here the two, fastening components 4 release the insertion anchor 14. If by mistake not all fastening components 4 are pressed so far that they release the insertion anchor 14 or its locking shoulders 15, then the remaining fastening components 4 prevent complete unlocking, so that the buckle components 6 and 7 can not then be separated.

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 shows a section through the female and the male buckle part 7 and 6 in the locked state along the drawn in Fig. 2 section line AA. Here, the region in which the two fastening components 4 are mounted so as to be pivotable about their respective pivot axes 8 by means of the axle bolts 9 is particularly easy to see. The axle bolts 9 used in this first exemplary embodiment are shown enlarged again in two alternative embodiments in FIGS. 15 and 16. 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. The insertion part 10 may be a screw, as shown in FIG. Alternatively, however, other embodiments, such as shown in Fig. 16, possible. Here it is the insertion part 10 is a rivet. By inserting the insertion part 10 into the respective recess 1 1 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 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 axle pin 9 that can be used as an alternative. It is designed in one piece or in one piece. In the exemplary embodiment shown, it carries spring tongues 23 with latching projections 24. By means of the latching projections 24, this axle pin 9 engages in the axle pin receptacle 16 when fully inserted, so that the axle pin 9 is anchored in the axle bolt receptacle 16 by means of its head 12 and its latching projections 24. 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 shows, detached from the other components of the buckle 1, the 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 member 4 is still the Achsbolzen- recording 16 located, through which the axle 9 can be passed. 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 mounting member 4 and 5, as shown separately in Figs. 7, 8 and 9, integrally as a plastic part. The injection molding here represents a cost-effective method for producing the parts. 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 are releasably connected to each other can, must have. The main body of the buckle 1 shown in Fig. 18 connects the two Gurtbefestigungselemente 2 of this second Ausführungsbei- game of FIG. 18 in one piece. 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 makes it possible to connect two differently wide straps 35 or straps to one another in an adjustable manner.

FIGS. 19 to 26 show further exemplary embodiments of belt buckles 1 according to the invention. The special feature of this, in addition to the inventively designed fastening components 4 and 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 FIGS. 19 and 20 form a set with a male buckle part 6 and two female buckle parts 7, wherein the female buckle parts 7 have different width belt fastening elements 2 for different width straps 35 and can be locked with the male buckle part 6 are. The same is true, just to give another example, for which 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 from each other different width Gurtbefestigungselemente 2 for have differently wide straps 35 and lockable in or on the female buckle part 6. Such a set is also formed by the belt buckles 1 shown in FIGS. 20 and 22. 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.
