Description

[0001]

[0002] buckle

[0003] The present invention relates to a buckle according to the preamble of patent claim 1.

[0004] Such buckles are known, for example, from EP 2 713 798 B1. With this type of buckle, the latches serve not only to lock the insertion part in the receptacle. Rather, such buckles also absorb the corresponding tensile forces when the two buckle parts are pulled apart in the locked position.

[0005] Other buckles of this type are shown in Figs. 26 to 35 of EP 3 581 057 B1. In these variants, the receptacle is rigid and hook-shaped, so that an insertion part, which is also rigid in itself and takes the form of a suspension part for absorbing the tensile forces when the buckle parts are pulled apart, is held back by this hook-shaped receptacle. With these buckles, the tensile forces on interconnected buckle parts are therefore not absorbed by movable parts in the form of latches, but by fixed parts or areas formed on the corresponding buckle base bodies.

[0006] Regardless of the aforementioned difference, all buckles of this type feature a spring-loaded, elastically pre-tensioned latch toward the locking position. In the current state of the art, each latch is assigned its own spring.

[0007] The object of the invention is to be able to assemble a generic buckle from as few individual parts as possible.

[0008] For this purpose, the invention proposes a buckle according to patent claim 1.

[0009] Starting from a generic buckle, it is thus provided that the latches are connected to one another by means of a spring element and the spring element elastically pre-tensions both latches in the direction of the locking position.

[0010] Unlike the prior art, the invention thus provides a single spring element to elastically preload both latches toward the locking position. Furthermore, it is also provided that the latches are connected to one another by means of the one or, in other words, a common spring element. This significantly reduces the number of parts required to assemble the buckle. Instead of two individual latches, each with its own associated spring, the latches together with the spring element according to the invention form a single component, which can also significantly simplify the assembly of the buckle according to the invention.

[0011] In particularly preferred embodiments, the spring element is integrally formed on both latches. It is also preferably provided that the spring element engages the respective latch on the side of the respective latch opposite the respective retaining surface.

[0012] In the interests of particularly simple assembly, very preferred variants of the invention provide that each of the latches is mounted on the first buckle base body so as to be pivotable about an axle bolt, each of the axle bolts being mounted so as to be elastically deflectable. In order to make the axle bolt elastically deflectable, the axle bolt can be designed so as to be elastically deflectable. However, it is preferably provided that each of the axle bolts is mounted on a spring tongue and can be elastically deflected with this spring tongue. The axle bolts can each be elastically deflected on the first buckle base body. Particularly preferred embodiments provide that each of the axle bolts is mounted so as to be elastically deflectable on the respective latch. In all of these variants, it is possible to integrate the two latches together with the spring element into the first buckle part or the second buckle part for assembly on the buckle.Push the first buckle body in until the pivot pins on the latch or on the first buckle body snap into place. This allows for particularly simple assembly of this combined component, consisting of the latches and the spring element, in the first buckle part.

[0013] Each of the latches preferably has, on the side of the respective latch opposite the respective retaining surface, an actuating surface protruding from the first buckle base body for manual actuation of the latch. Manual actuation is advantageously carried out using the fingers of the person using the buckle. Preferred variants of the invention provide for the spring element to have a U-shaped bent area between the latches. This allows the elasticity of the spring element to be achieved particularly well. In preferred embodiments, however, it is also provided that the first buckle base body has an opening and the spring element is guided at least partially around the opening, at least in an initial position of the spring element. This makes it possible to achieve a particularly compact design.It is particularly preferred that the spring element is guided around the opening with the U-shaped bent area, in other words the U-shaped bent area surrounds the opening of the first buckle base body at least in part.

[0014] A further aspect of the invention relates to a buckle according to the preamble of patent claim 7. This aspect can be realized or viewed in combination with the previously described invention, but also independently thereof. The problem to be solved with this aspect of the invention is to particularly well secure the two buckle parts against lateral tilting relative to one another when connected to one another and in the locking position of the latch.

[0015] For this purpose, this aspect of the invention proposes a buckle according to claim 7.

[0016] Thus, based on the preamble of claim 7, it is provided in this case that one of the, preferably the first, buckle base bodies has an opening, the opening being delimited on one side by an end web, and an anti-tilt hook is formed on the other, preferably on the second, buckle base body, preferably on the insertion part, the anti-tilt hook being insertable into the opening when the two buckle parts are connected to one another, and the anti-tilt hook engaging around the end web in a connected end position of the two buckle parts.

[0017] By gripping the end bar that limits the opening in the first buckle body, the anti-tilt hook prevents the first and second buckle bodies from tilting against each other.

[0018] The anti-tip hook can also be designed so that, when the buckle parts are connected, it can absorb tensile forces when the two buckle parts are pulled apart in at least one of the possible pulling directions. The pulling directions are the directions in which the buckle parts are normally pulled apart when they are connected and subjected to corresponding stress by pulling apart.

[0019] The opening in the first buckle base body is advantageously designed as an elongated hole. It is preferably provided that the elongated hole is longitudinally extended parallel to the said pulling direction(s) of the buckle. The opening in the first buckle base body, into which the anti-tilt hook engages and which is advantageously designed as an elongated hole, is advantageously the opening around which, as already explained above, in preferred embodiments the spring element is guided, preferably with its U-shaped bent area. In buckles according to the invention, it can be provided, similar to EP 2 713 798 B1 mentioned at the outset, that the latches are not only intended for locking, but that the forces acting on the interconnected buckle parts when pulling in the pulling direction are also absorbed by the latch(es).

[0020] However, it is more advantageous if these forces acting in the pulling direction(s) on the interconnected buckle parts are supported or absorbed by parts rigidly arranged on the two buckle base bodies. For this purpose, it is advantageously provided that the receptacle is designed to be rigid in itself, and in particular hook-shaped, on the first buckle base body and the insertion part is designed as a rigid suspension part for hanging in the receptacle. It is particularly preferably provided that the insertion part designed as a suspension part has a central web and two side parts protruding from the central web on opposite sides and each of the side parts is delimited by a front edge and the front edges of the side parts are aligned so as to diverge obliquely from one another at least in some areas from the central web, preferably in a V-shape to one another at least in some areas.

[0021] The front edges, and thus also the side parts of the suspension part, which diverge at least partially from the central web at an angle to one another, make it possible to create a buckle with a relatively short overall length, while the special design of the side parts and their front edges means that the two buckle parts, when hooked into one another, are relatively well secured against tilting in a direction orthogonal to the direction of pull. The front edges are the edges that delimit the side parts and which point into the receptacle when the suspension part is pulled in one of the directions of pull. These front edges can be straight in themselves but can also be curved. The front edges of the side parts protruding from the two opposite sides of the central web are particularly preferably aligned in a V-shape to one another, at least in some areas.The leading edges or even just parts of the leading edges therefore advantageously run towards each other at an acute or obtuse angle in the direction of the central web.

[0022] Particularly preferred variants of the invention provide that the side parts together, optionally together with the central web, form a dovetail shape. Since the entire suspension part in such variants is rigid in itself, the side parts are also necessarily rigid on the central web. The central web and the two side parts together form the suspension part, although it is not excluded that the suspension part also has further components. The suspension part is in any case part of the second buckle base body of the second buckle part. In addition to the suspension part, the second buckle base body can have, for example, a belt web for wrapping a belt around it and / or a corresponding belt receiving window through which the belt is pushed.The strap bar can be rigid or movable, particularly displaceable, for clamping a strap to the second buckle base body, i.e., as a clamping bar. The second buckle base body can be a rigid component as a whole. However, it can also have movable parts, such as a displaceably mounted strap bar or clamping bar.

[0023] As already explained, the receptacle is preferably rigidly formed on the first buckle base body. In addition to the receptacle, the first buckle base body can also have a belt web and a belt-receiving window, or in other words, a belt-receiving opening. Here, too, the belt web can be rigid or can be formed as a movable, in particular displaceable, clamping web on the first buckle base body.

[0024] The latch(es) are arranged on the first buckle base body so that they can pivot between the locking position and the unlocking position. When the hook-in part is hooked into the receptacle, the latch(es) hold the hook-in part or insert part firmly in the receptacle with their retaining surfaces in the locking position so that the two buckle parts cannot be accidentally separated. The two buckle parts can only be separated once the latch(es) have been moved into their unlocking position. In the unlocking position, the hook-in part or insert part can then be taken out of the receptacle in order to separate the two buckle parts.

[0025] In principle, buckles according to the invention can be designed in very different ways and serve very different purposes. Basically, they serve to detachably connect two components. Buckles according to the invention are particularly preferably so-called belt buckles, which serve to connect one belt to another belt or one belt to another component.

[0026] Accordingly, options such as the aforementioned belt bars are provided on the buckle parts to which the belts can be attached. Instead of a belt bar, however, other fastening options, or in other words connection options, such as fastening holes on the buckle parts, can also be provided. Belts or, if there is no belt buckle, other objects can then be attached to these other fastening options. In the case of a belt buckle, the belt bars or clamping bars of the buckle parts can also be of different lengths in order to be able to connect belts of different widths to one another. The widths of the buckle parts can of course also be adapted to the belt widths of the belts to be connected to one another.

[0027] It is preferably provided that each of the side parts is delimited by a rear edge of the side part on a side opposite the respective front edge of the side part and the at least one retaining surface of the latch or latches in the locking position forms a stop surface for the rear edges of the side parts of the hanging part or insertion part suspended in the receptacle.

[0028] Particularly preferred variants provide that the rear edges of the side parts are aligned so as to diverge from one another at an angle, at least in some regions, from the central web, preferably in a V-shape to one another, at least in some regions. The rear edges can also be straight or curved. Preferred variants of the invention provide that the front edges of the side parts form an angle with one another in an angular range of 20° to 160°, preferably of 60° to 120°. The same applies in preferred embodiments to the rear edges of the side parts. These also form an angle with one another, which is preferably in an angular range of 20° to 160° and particularly preferably of 60° to 120°.In the case of front and / or rear edges which are only partially aligned in a manner that diverges from the central web relative to one another, these angle specifications then preferably only apply to the correspondingly diverging areas.

[0029] Particularly preferred variants of the invention provide that on the suspension part only a portion of the respective front edge is formed as a contact shoulder and on the first buckle base body corresponding counter-contact shoulders are formed, wherein in the suspended state of the suspension part in the receptacle when the suspension part is pulled in a pulling direction into the receptacle, the tensile forces in the pulling direction can be transmitted from the suspension part to the first buckle base body exclusively via the contact of the contact shoulders on the counter-contact shoulders. In such embodiments, the tensile forces which engage on the two buckle parts in the pulling direction are transmitted exclusively via the contact of the contact shoulders on the corresponding counter-contact shoulders.The remaining areas of the front edge of the respective side part of the suspension part are released in the receptacle when attached, so that no forces are transferred from one buckle part to the other buckle part in the direction of pull. However, this release of the areas of the front edges lying outside the contact shoulder, which only acts in the direction of pull, can prevent the front edges of the side parts, which diverge obliquely relative to one another and are arranged in a particular V-shape, from spreading against the first buckle part or the receptacle. The side parts then serve, through their interaction with the receptacle, essentially to secure the two buckle parts against tilting against one another. If the two buckle parts tilt against one another, this is to be understood here and elsewhere in this description as meaning tilting against one another about an axis orthogonal to the direction of pull.In this sense, it is advantageously provided that the contact shoulders are each arranged in a half of the respective front edge facing the central web. The contact shoulders preferably border directly on the central web. The contact shoulders can each be designed as an undercut that is rounded at least in some areas. As already indicated, the side walls of the receptacle of the first buckle base body, when the suspension part is suspended in the receptacle, preferably form lateral stops for the front edges of the side parts to prevent the suspension part from tipping sideways out of the receptacle in a direction orthogonal to the direction of pull.

[0030] As a further or different measure to support the interconnected buckle parts against tilting, it can be provided that the insertion part has a support plate for supporting the second buckle part on the first buckle part to prevent the two buckle parts from tilting against each other. In this case, it is preferably provided that the support plate is rigidly formed on the central web and spaced from the side parts. To make it easier to insert the insertion part or the suspension part into the receptacle, it can be provided that bevelled chamfers are formed on the front edges of the side parts and / or on the side walls of the first buckle base body forming the receptacle as an insertion aid when inserting the insertion part or suspension part into the receptacle. The said chamfers or beveled surfaces can be designed such that the orthe latches do not have to be operated separately when inserting the hanging part into the holder, but are automatically pushed from their locking position into the unlocking position so that the insertion part or hanging part can be inserted past them into the holder.

[0031] In the hooked-in state and when the latch(s) is / are in the locked position, the hooking part or insertion part is in any case advantageously arranged in a receiving opening, preferably open to the side, of the first buckle base body and in the receptacle and / or locked between the receptacle and the latch(s) or its / their retaining surface(s). The hooking part or insertion part can preferably only be removed from the receptacle to separate the buckle parts when the latch(s) is / are deliberately brought into its unlocking position, preferably by manual operation.

[0032] A further aspect of the invention, which can be seen in combination with what has been said above, but also independently thereof, relates to a belt buckle which has a belt receiving window and a clamping bar which is displaceably mounted in the belt receiving window for clamping a belt between the clamping bar and a frame of the belt buckle which delimits the belt receiving window.

[0033] Such a belt buckle is known per se from the documents already mentioned above. A new type of clamping bar is proposed. For this purpose, the invention provides a belt buckle according to patent claim 14.

[0034] In this aspect of the invention, the clamping web therefore has an outer shell with a belt contact surface for contact with the belt and an inner web, wherein the outer shell has a web receiving channel leading through the outer shell and the inner web can be pushed through the web receiving channel for displaceable fastening of the clamping web to the frame surrounding the belt receiving window.

[0035] This allows for particularly simple installation of such a clamping bar in the belt receiving window or on the frame surrounding this belt receiving window. For installation, the outer shell can be inserted laterally into the belt receiving window, and the inner bar can then be pushed through the bar receiving channel to the appropriate extent.

[0036] In order to be able to easily adjust the achievement of a defined end position of the inner web in the web receiving channel and also to maintain it permanently, preferred variants provide that the inner web can be locked in an end position inserted through the web receiving channel by means of a locking connection acting between the inner web and the outer shell, preferably in a non-destructively releasable manner.

[0037] To increase the friction between the outer shell or the clamping bar and the belt, the belt contact surface of the outer shell can be provided with knobs, ribs, teeth, or other shaped elevations. Of course, it is also possible to provide the belt contact surface with a roughened surface in some other way, or even with a smooth surface.

[0038] Such a belt buckle can consist of a single buckle part with a single buckle body. However, such a belt buckle can also be designed like the buckles already described above.In particular, it can therefore be a buckle with a first buckle part and at least one second buckle part, wherein the first buckle part has a first buckle base body and a receptacle formed on the first buckle base body and the second buckle part has a second buckle base body with an insertion part for insertion into the receptacle of the first buckle part and the first buckle part additionally has one or two latches which are each pivotably mounted on the first buckle base body, wherein the insertion part, when inserted into the receptacle, is held in the receptacle by at least one retaining surface of the respective latch in a locking position of the latch(s) and can be removed from the receptacle in an unlocking position of the latch(s).

[0039] Buckles and belt buckles according to the invention can be made with all their components completely from metal or metal alloys, such as aluminum or steel, but also completely from plastic. Mixed forms are also conceivable, in which parts of the respective buckle or belt buckle are made from plastic and others from metal or a metal alloy. It is particularly preferred that the two latches connected to one another by means of a spring element are designed together with the spring element as a single component made of plastic. This also applies to the axle bolts, which can be elastically deflected if necessary, insofar as they are part of this connected component. Of course, the latter-mentioned outer shell and / or the inner web can also be made from plastic or from metal. The same applies to the buckle base body and the other components of the respective buckle or belt buckle.

[0053] Fig. 16 shows the section along the section line EE from Fig. 14 and

[0054] Fig. 17 shows the section along the section line FF from Fig. 15.

[0055] The buckle 1 according to the invention shown in the figures is a belt buckle which is used to connect two different belts to one another. The buckle 1 of this exemplary embodiment has a first buckle part 2 and a second buckle part 3. These two buckle parts 2 and 3 are shown in the connected state in Figs. 1 to 6. When this buckle 1 is loaded, the two buckle parts 2 and 3 are normally or in the usual load case loaded in the tensile directions 30 shown in the figures, or in other words pulled apart.

[0056] The first buckle part 2 has a first buckle base body 4, on which a receptacle 5 is formed, explained further below with reference to Fig. 4. The second buckle part 3 has a second buckle base body 6 with an insertion part 7, which, as shown and described further below, serves for insertion into the receptacle 5 of the first buckle part 2. The first buckle part 2 additionally has two latches 8, each pivotably mounted on the first buckle base body. If the insertion part 7 is inserted into the receptacle 5, or in this embodiment is hooked in, and the latches 8 are in their locking position, each latch 8 holds the insertion part 7 firmly in the receptacle 5 with its retaining surface 9. In the unlocking position of the latch 8 , the insertion part 7 , which is designed here as a suspension part, can be removed from the receptacle 5 .It is provided here that the latches 8 are connected to one another by means of a spring element 10, and the spring element 10 elastically preloads both latches 8 toward the locking position. The interconnection of the two latches 8 by means of the spring element 10 is particularly clearly visible in Figs. 7 to 10 and will be explained in more detail below.

[0057] On the buckle base bodies 4 and 6 of the two buckle parts 2 and 3, belt receiving windows 22 are each formed for attaching a belt, which are surrounded by a frame 24 or a frame-shaped structure of the corresponding buckle base body 4 or 6. These belt receiving windows 22 or the frames 24 surrounding them serve to attach a belt (not shown separately here) to the respective buckle base body 4 or 6, as is known per se. On the first buckle part 2 of this exemplary embodiment, a part of the frame 24 is designed as a fixed web 37.If the corresponding belt (not shown here) is guided through the belt receiving window 22 and around the fixed web 37, as is known per se, the belt can be fastened to the first buckle part 2 by appropriately sewing, gluing or otherwise connecting the belt areas guided around the fixed web 37. In the second buckle part 3 of this exemplary embodiment of a buckle 1 according to the invention, a clamping web 23 is provided in the belt receiving window 22, which clamping web is mounted on the frame 24 so that it can be moved in both pulling directions 30, as is known per se. To fasten the belt (not shown here) to the second buckle part 3, this belt is guided through the belt receiving window 22 of the second buckle part 3 and around the clamping web 23 in a manner known per se.By subsequently pulling on the belt in the pulling direction 30 pointing away from the first buckle part 2, the clamping web 23 is then moved in the belt receiving window 22 in the said direction 30 such that the belt is clamped firmly between the clamping web 23 and the frame 24 in the belt receiving window 22 in the manner known per se. These clamping webs 23 have, as is known per se, the advantage that the belt length can be adjusted by pushing the clamping web 23 out of the clamping position and readjusting the belt accordingly before clamping it again between the clamping web 23 and the frame 24 by pulling accordingly in the corresponding pulling direction 30. Such a design of clamping webs 23 and fixed webs 37, as has been described so far, is known per se. In contrast to the exemplary embodiment shown here, the first buckle part 2 or on the first buckle base body 4 a corresponding clamping web 23 is formed.Just as well, a corresponding fixed web 37 could be formed on the second buckle part 3 or on its second buckle base body 6 instead of the clamping web 23. Furthermore, it would also be possible to form differently sized strap receiving windows 22 or clamping webs 23 or fixed webs 37 on the corresponding buckle parts 2 and 3 in order to connect straps of different widths to one another using the buckle 1.

[0058] The clamping bar(s) 23 of such buckles 1 could, in principle, be designed as is known per se in the prior art. However, in the exemplary embodiment shown here, the clamping bar 23 has, according to a further aspect of the invention, an outer shell 25 and an inner bar 27, as will be explained in more detail below.

[0059] The connection of the two latches 8 to one another by means of the spring element 10 can be seen particularly well in the exploded view according to Fig. 7 and in Figs. 8 to 10. There one can also clearly see that in this exemplary embodiment, as in other preferred variants, the spring element 10 is formed in one piece onto both latches 8. Between the latches 8, the spring element 10 shown here has a U-shaped bent area 11. It can also be clearly seen that each latch 8 has a retaining surface 9 as already explained above. In the locking position shown in Fig. 6, these retaining surfaces 9 hold the insertion part 7 of the second buckle part 3 in the receptacle 5 of the first buckle part 2, so that the two buckle parts 2 and 3 cannot be separated from one another.If the two latches 8 are pivoted about their respective axle bolts 12 into the respective unlocking position by correspondingly pressing on the actuating surfaces 14, their retaining surfaces 9 release the insertion part 7 so that the two buckle parts 2 and 3 can be separated from one another. This pivoting of the latches 8 from the locking position into the unlocking position takes place against the elastic pretension of the spring element 10. The spring element 10 is therefore elastically deformed when the latches 8 are correspondingly pivoted from the locking position into the unlocking position by pressing on the actuating surfaces 14, in that in this exemplary embodiment the two legs of the spring element 10 are moved towards one another in the U-shaped bent area 11. As soon as the actuating surfaces 14 are released orare released, the spring element 10 presses again on the two bolts 8 so that they are automatically pivoted around the axle bolts 12 from the unlocked position back into the locking position shown in Fig. 6 to 10. Preferred variants such as the one shown here provide that the spring element 10 acts on the respective bolt 8 on the side of the respective bolt 8 opposite the respective retaining surface 9. In preferred embodiments such as the one shown here, the actuating surface 14 for manually actuating the bolt 8 is also located there. This manual actuation is generally carried out by pressing the actuating surfaces 14 with a finger.To release the insertion part 7, in preferred embodiments such as the one shown here, both latches 8 must be brought into the unlocking position by appropriately pressing on the actuating surfaces 14. This is a safety aspect, since the separation of the two buckle parts 2 and 3 is only possible if both latches 8 are specifically actuated. In embodiments such as the one shown here, this prevents an accidental actuation or pivoting of only one latch 8 from leading to an accidental complete unlocking and thus to the separation of the two buckle parts 2 and 3.

[0060] In the exemplary embodiment shown here, the axle bolts 12 are each mounted so as to be elastically deflectable. For this purpose, they could themselves be elastically deformable. In the variant shown here, however, the axle bolts 12 are each arranged on a spring tongue 13 to achieve their elastic deflectability. This spring tongue 13 is formed on the respective latch 8 in the exemplary embodiment shown here. This allows particularly simple assembly of the component comprising the latches 8 and the spring element 10 in the first buckle part 2 by inserting the latch 8 with the spring element 10, starting from the position shown in Fig. 7, into a corresponding housing opening 38 of the first buckle part 2.During this insertion process, the spring tongues 13 with the axle bolts 12 respectively arranged thereon are elastically deflected until the axle bolts 12 then engage in the corresponding axle bolt receptacles 33 of the first buckle base body 4 of the first buckle part 2, whereby the latches 8 with the spring element 10 are then mounted in the first buckle base body 4. Of course, deviating from the embodiment shown here, in which the axle bolts 12 are mounted on the respective latch 8 by means of the spring tongue 13 so that they can be elastically deflected, it would also be possible to form corresponding axle bolts 12, with or without the spring tongue 13, so that they can be elastically deflected on the first buckle base body 4. In this case, the axle bolt receptacles 33 would then be formed on the latches 8.Even with this modified embodiment, it would then be possible for the pivot pins 12 to deflect elastically and then engage during assembly of the latches 8 with the spring element 10 in the first buckle base body 4, in order to enable particularly simple assembly of the latches 8 with the spring element 10 in the first buckle base body 4. Deviating from this, it would also be possible to design the pivot pins 12 to be correspondingly rigid on the latches 8 or on the first buckle base body 4 if the corresponding pivot pin receptacles 33 on the respective counterpart were designed to be correspondingly elastically deflectable.

[0061] In preferred embodiments, such as the buckle 1 realized here, it is provided that the receptacle 5 of the first buckle base body 4 of the first buckle part 2 is designed to be rigid and hook-shaped on the first buckle base body 4 and the insertion part 7 of the second buckle part 3 is designed as a rigid suspension part for hanging in the receptacle 5.

[0062] 7, it is furthermore advantageous if the insertion part 7 has a central web 18 and two side parts 19 projecting from the central web 18 on two opposite sides, and each of the side parts 19 is delimited by a front edge 20 and the front edges 20 of the side parts 19 diverge obliquely from one another, at least in some regions, from the central web 18. Preferably, the side parts 19 are aligned in a V-shape relative to one another, as is also the case here. In the section shown in Fig. 6 along the section line CC from Fig. 5, the central web 18 and the side parts 19, which are aligned in a V-shape relative to one another, can be clearly seen. In Fig. 6, one can clearly see the central web 18 and the side parts 19, which are aligned in a V-shape relative to one another, with their front edges 20.6 it can also be seen that on the insertion part 7 designed as a suspension part, only a partial area of ​​the respective front edge 20 is designed as a contact shoulder 31 and that corresponding counter-contact shoulders 32 are formed on the first buckle base body 4. This makes it possible, in preferred embodiments of buckles 1, such as the one shown here, when the insertion part 7 is suspended in the receptacle 5, when the insertion part 7 is pulled in the pulling direction 30 away from the first buckle part 2 and thus into the receptacle 5, the tensile forces in the pulling direction 30 can be transferred from the insertion part 7 to the first buckle base body 4 exclusively via the contact of the contact shoulders 31 on the counter-contact shoulders 32.In such embodiments, the tensile forces acting on the two buckle parts 2 and 3 in the respective tensile directions 30 are transmitted exclusively via the contact shoulders 31 against the corresponding counter-contact shoulders 32. The remaining areas of the front edges 20 of the side parts 19 of the insertion part 7, which is designed here as a suspension part, are exposed in the suspended state in the receptacle 5 in the tensile directions 30, as can also be clearly seen in Fig. 6, so that no forces are transmitted from one buckle part 2 or 3 to the other buckle part 2 or 3 via them in the tensile directions 30.As already explained at the beginning, this release of the areas of the front edges 20 lying outside the contact shoulders 31, which only acts in the pulling direction 30, can prevent a spreading effect of the front edges 20 of the side parts 19, which run apart obliquely relative to one another and are arranged in a V-shape, on the first buckle part 2 or the receptacle 5. The side parts 19 then also serve in this exemplary embodiment through their interaction with the receptacle 5 essentially to secure the two buckle parts 2 and 3 against tilting relative to one another. Tilting is understood here to mean tilting of the buckle parts 2 and 3 relative to one another about an axis orthogonal to the pulling direction 30. The receptacle 5 of the first buckle base body 4 with a side part 19 arranged therein can be clearly seen in the section in Fig. 4 running along the section line BB in Fig. 1. The two front edges 20 of the side parts 19 shown in Fig.4 The wall regions of the first buckle base body 4 forming the receptacle 5, between which the side part 19 is arranged, are connected to one another by wall regions of the first buckle base body 4 that are not visible in this section according to Fig. 4, in such a way that the receptacle 5 has an overall hook-shaped design into which the insertion part 7, specifically here with its side parts 19, can be hooked. This inherently rigid hook-shaped design of the receptacle 5 of the first buckle base body 4 and the interaction with the central web 18 and the side parts 19 of the insertion part 7, designed as a suspension part, of the second buckle part 3 or second buckle base body 6 is known per se from the aforementioned EP 3 581 057 B1 and its advantages are described in detail there.This also applies to the absorption of the tensile forces in the tensile directions 30 by the contact shoulders 31 and the counter-contact shoulders 32, so that this does not need to be explained in detail here again.

[0063] However, it should be noted that in the buckle 1 shown here, further measures have been taken to prevent the two buckle parts 2 and 3 from tilting against each other in a direction orthogonal to the pulling direction 30, which measures are not implemented in the cited prior art. A first measure consists in the insertion part 7 having a support plate 21 for supporting the second buckle part 3 on the first buckle part 2, which also prevents the two buckle parts 2 and 3 from tilting against each other. This support plate 21 can be clearly seen in Figs. 1, 7 and 15 and, in this embodiment too, is rigidly attached to the central web 18 and spaced from the side parts 19.

[0064] 2, 3 and 7. According to the second aspect of the invention, this measure consists in that one of the, here the first, buckle base bodies 4 has an opening 15, the opening 15 being delimited on one side by an end web 16 and an anti-tilt hook 17 is formed on the other, here the second, buckle base body 6, the anti-tilt hook 17 being insertable into the opening 15 when the two buckle parts 2 and 3 are connected to one another and engaging around the end web 16 in a connected end position of the two buckle parts 2 and 3. This end position is shown in Fig. 2 and also in the section according to Fig . 3 . In particular in Fig .In Fig. 3, one can clearly see how the anti-tilt hook 17 is guided through the opening 15 and engages the end web 16 in such a way that tilting of the two buckle parts 2 and 3, upwards or downwards as seen in Fig. 3, relative to one another is prevented. For the sake of completeness, it should be noted in this context that the anti-tilt hook 17, through its interaction with the web 16, can also absorb additional forces in the tensile directions 30 if this is desired and designed accordingly.

[0065] The opening 15 of the first buckle base body 4 is advantageously designed as an elongated hole, as can be seen in particular in Figs. 2, 3, 7 and 14. The elongated hole is advantageously designed to be longitudinally extended parallel to the pulling directions 30 of the buckle 1, as is also realized here.

[0066] With regard to this opening 15 in the first buckle base body 4, it should also be pointed out that in this exemplary embodiment, too, the spring element 10 with its U-shaped bent region 11 is guided at least partially around this opening 15, at least in its initial position.

[0067] According to a further aspect of the invention, as already explained at the outset, provision is made for the clamping web 23 to have an outer shell 25 with a belt contact surface 26 for contact with the belt and an inner web 27, the outer shell 25 having a web receiving channel 28 leading through the outer shell 25 and the inner web 27 being able to be pushed through the web receiving channel 28 for the displaceable fastening of the clamping web 23 to the frame 24 surrounding the belt receiving window 22. This further aspect of the invention is also implemented in the clamping web 23 present here on the second buckle part 3 in this exemplary embodiment. This can be seen particularly well in Figs. 3, 4 and 6. Fig. 11 additionally shows the outer shell 25 of the clamping web 23 in a cross section. Fig. 12 shows a longitudinal section along the section line DD from Fig. 11. Fig. 13 shows the inner web 27 . In the section according to Fig .12 also shows the inlet bevels 42 formed on the outer shell 25, which could also be referred to as chamfers. These inlet bevels 42 facilitate the insertion of the inner web 27 into the web receiving channel 28 of the outer shell 25. In this exemplary embodiment, the inlet bevels 42 are formed at both ends, but only on one side of the web receiving channel 28 in the outer shell 25. As an alternative to this, corresponding inlet bevels 42 could be formed on both sides of the web receiving channel 25, preferably symmetrical to one another, and / or one or two corresponding inlet bevels 42 could be formed in the outer shell 25 only at one end of the web receiving channel 25. In this embodiment, it is also provided that the inner web 27 can be locked in a non-destructive manner in an end position inserted through the web receiving channel 28 by means of a locking connection 29 acting between the inner web 27 and the outer shell 25.For this purpose, in this exemplary embodiment, as can be seen in particular in Fig. 13, an elastically deflectable locking arm 39 with a locking lug 40 is provided on the inner web 27. The outer shell 25, on the other hand, has a locking receptacle 41, as can be seen in particular in the longitudinal section according to Fig. 12. The locking lug 40 and the locking receptacle 41 together form the locking connection 29 when the inner web 27 is pushed sufficiently far into the outer shell 25 through the web receptacle channel 28 and the locking lug 40 clicks into the locking lug receptacle 41 in the desired end position due to the elastic pretension of the locking arm 39. This locking connection 29 can, however, also be released again by appropriately pressing on the engaged locking lug 40, so that the inner web 27 can be pushed out of the outer shell 25 again, if desired.For the sake of completeness, it should be noted that such a locking connection 29 between the inner web 27 and the outer shell 25 of the clamping web 23 could of course also be designed differently. For example, it would be conceivable to provide a corresponding locking lug 40 on the outer shell 25 and a corresponding locking lug receptacle 41 on the inner web 27. Of course, several such locking connections 29 could also be realized in order to lock the inner web 27 to the outer shell 25 in the pushed-through end position. In contrast to the variant shown here, the locking connection 29 could also be designed symmetrically, so that for the locking connection 29 to engage it is irrelevant which way the inner web 27 is pushed into the outer shell 25. This would be possible, for example, by providing a corresponding locking lug receptacle 41 on both opposite sides of the outer shell 25. This locking connection 29 is of course only optional.They could also be dispensed with, e.g. if the inner web 27 were held in its final position by a corresponding positive and / or frictional engagement in the outer shell 25.

[0068] Finally, it should be noted that, as is also the case here, the belt contact surface 26 of the outer shell 25 can have elevations 36, e.g., knob-like, in order to increase the friction between the belt wrapped around the clamping web 23 and the belt contact surface 26. However, as already explained at the beginning, such elevations 36 can also be omitted.

[0069] 14 and 15, the buckle parts 2 and 3 are shown again separately from one another, whereby the latches 8 are not shown in Fig. 14 and the clamping web 23 is not shown in Fig. 15. Fig. 16 shows the section along the section line EE from Fig. 14. Fig. 17 shows the section along the section line FF from Fig. 15. In Figs. 7 and 17 it can be clearly seen that in the area of ​​the second buckle part 3 forming the frame 24, insertion openings 34 are formed through which the inner web 27 can be pushed into the outer shell 25, which is correspondingly inserted into the belt receiving window 22, for assembly. If the arrangement shown in Fig. 6 particularly well illustrated end position of the inner web 27 in the outer shell 25 is reached, the clamping web 23 can be pushed back and forth along the web guides 35 in the frame-shaped structure 24 of the second buckle base body 6 parallel to the pulling directions 30.If the clamping web 23 is to be dismantled, it is moved in the web guides 35 so far that the inner web 27 can be pushed out of the outer shell 25 through one of the insertion openings 34 after the locking connection 29 has been released.
