Description

The invention relates to a buckle assembly comprising a first buckle and a second buckle connectable to the first buckle, the first buckle having a first locking means and a first locking hook, and the second buckle having a second locking means and a second locking hook.

Belt buckles are known in the art and are used to releasably connect belts or releasably secure a belt to another object. Such buckles are used mainly in the field of mountain sports, air sports, military and in the field of personal protective equipment for occupational safety or the like, and are often part of climbing harnesses or similar fall arrest systems. On the one hand, due to the above-mentioned areas of use, buckles must function very reliably, since the life or at least the health of a user secured with the buckles depends on the correct functioning of the buckles, while on the other hand no accidental incorrect operation may occur. With regard to these requirements, the configurations known from the prior art have a locking device which often has to be locked in a complex manner in order then to prevent inadvertent opening of the belt buckles in the locked state. A disadvantage of such embodiments is that the buckles have very elaborately designed locking devices that are locked in an equally complex manner and unlock.

Based on this, it is an object of the invention to provide a first buckle and connectable to the first buckle second buckle, which are connected to one another in a particularly simple manner and detachable from each other, and / or can be produced in a particularly cost-effective manner.

The object of the invention is solved by the features of the independent claim. Preferred developments are specified in the subclaims.

After a preferred embodiment presented below, the first buckle and the second buckle can also be designed completely identical. For a belt buckle assembly may then only two identical buckles a single belt buckle model, which greatly simplifies the production. The buckle assembly is characterized by two independent locks, on the one hand by the first locking means with the second locking hook and on the other hand by the second locking means with the first locking hook. The thus connected to the first buckle second buckle has a secure and very reliable connection that meets the normative and / or legal requirements in mountain sports, air sports, in the field of safety at work and / or personal protection. Finally, the first buckle of the second buckle for a further discussed below preferred development is only solvable when both locking devices operated simultaneously become. As a result, a secure and simple connection of the first buckle and the second buckle is made possible by the proposed Gurtschnallenanordnung, wherein the risk of unintentional release of the first buckle and second buckle is minimized, and also the Gurtschnallenanordnung due to the at least partially the same or symmetrical structure of the Belt buckles is particularly easy and inexpensive to produce.

The first buckle and / or the second buckle preferably have a means for attachment and / or hanging a belt, a carabiner or the like, such as a hook-in etc. The buckle may be part of a climbing harness, or other collection system in the to be personal safety. In addition, other applications are conceivable, especially in mountain sports, in aviation or in the field of personal protective equipment or the military. A belt that can be connected to the belt buckle may be a known belt material, in particular a flat, flexible and / or elongate object with a relatively smaller width relative to the length. Advantageously, such a belt, also called band, polyester and / or polyamide, and / or has a width of ≥ 30 mm and ≤ 45 mm. In a corresponding embodiment, the first buckle and / or the second buckle can also be attached to a rope.

Furthermore, the first buckle and / or the second buckle may have a fixed or a displaceable web, a so-called clamping web, around which the belt and / or the rope is wound in order to establish a connection between the belt and the buckle. While fixed webs are not usually provided for adjusting the belt, slidable clamping webs are suitable for adjusting the belt length. The locking between locking device and locking hook and / or the connection between the first buckle and second buckle is due to appropriate design of the locking device, the locking hook and / or the buckle preferably positive and / or non-positive. If spoken in the context of the invention of locking, so for example, in terms of equal and / or symmetrical locking of Verriegelungseimichtung with locking hooks, so is in particular the part of The locking direction or the locking hook meant, which is locked together or is locked. Preferably, the symmetrical or point-symmetrical configuration can be recognized, in particular, when the first belt buckle is connected to the second belt buckle, ie the two locking devices have locked the respective locking hook.

Fig. 1 shows a buckle assembly according to a preferred embodiment of the invention in a plan view, comprising a first buckle 1 and connected to the first buckle 1 second buckle 2. Such connect the two buckles 1 and 2 each connected to the respective buckle 1, 2 belt third a climbing harness, not shown. The belt 3 is made of textile, whereby polyamide or the like is possible, and has a width of 45 mm. How better Fig. 2 can be seen, each of the two buckles 1, 2 has a rectangular belt opening 4, through which the belt 3 in the in Fig. 1 shown illustration for fastening a respective buckle 1, 2 is guided. The belt opening 4 extends longitudinally perpendicular to the connection direction v of the belt buckles 1, 2.

The two buckles 1, 2 are presently configured identically, which means that together with a third buckle, not shown, any two of the three buckles 1, 2 are connected to each other. In concrete terms, the first buckle 1 has a first locking device 5 and a first locking hook 6. The second buckle 2 has a second locking device 7 and a second locking hook 8. According to the above, the first locking device 5 and the second locking device 7 are configured identically and the first locking hook 6 and the second locking hook 8 are configured identically.

In other words, how are out Fig. 1 and 2 can be seen, the two buckles 1, 2, based on the in Fig. 1 shown connected state, with respect to a symmetry point 9 point-symmetrical or mirror-symmetrical configured. Accordingly, the locking means 5, 7 and the locking hooks 6, 8 with respect to the symmetry point 9, which also in the one non-connected state of the buckles 1, 2 facing Fig. 2 is located, arranged mirror-symmetrically.

When connecting the first buckle 1 with the second buckle 2, the first locking device 5 locks the second locking hook 8 and the second locking device 7 locks the first locking hook 6. Due to the identical configuration of the first buckle 1 and second buckle 2 unlocking can only be achieved by simultaneous operation the two locking devices 5, 7 take place. Moreover, as is apparent from the following detailed description of the locking hooks 6, 8 and the locking means 5, 7 that unlocking is only possible if no train on the two buckles 1, 2 or in Fig. 1 shown connected to the two buckles 1, 2 straps 3 acts.

For further description of the buckles 1, 2 is on the in 3 and 4 shown first buckle 1 referenced. Since the two buckles 1, 2 are configured identically, the following applies to the 3 and 4 Said also for the second buckle 2 and the second locking hook 8 and the locking device. 7

How out Fig. 3 can be seen, the first locking hook 6 has a connection extension 9. While the belt opening 4 is arranged on one side of the first belt buckle 1, the connection extension 9 or the first locking hook 6 extends on the other, opposite side in the connecting direction v away from the belt opening 4 in a direction substantially perpendicular to the longitudinal extent of the belt opening 4. At the top of the connection extension 9, a retaining lug 10 protruding on one side in the transverse direction is arranged, which forms an undercut 11.

On the side opposite the retaining lug 10, a guide surface 12 extending essentially in the connection direction v is formed, the surface normal of which extends essentially in the direction of the longitudinal extension of the belt opening 4. The first locking device 5 has a pawl 13 pivotally mounted between an open position and a closed position. The pivot axis of the pawl 13 extends out of the plane of the drawing in the direction of the surface normal of the surface of the first belt buckle 1.

The first buckle 1 has a base body, which is formed of two symmetrically designed to each other parts 14, 15. I'm mounted in Fig. 3 shown state of the first buckle 1 are the two parts 14, 15 congruent to each other and are in the region of the locking hook 6 and in the region of the belt opening touching each other and thus form the first locking hook 6 and the belt opening 4. In Fig. 4 is the upper part 15 of the base body of the lower part 14 of the base body dissolved and pivoted against the connecting direction v to a longitudinal extent of the belt opening 4 extending axis. In this way, it can be seen that the two parts 14, 15 each have a region 16 arranged offset by a pressing process and extending in parallel, which in the assembled state of the two parts 14, 15 as in FIG Fig. 3 shown forms an insertion opening for insertion of the second locking hook in the first buckle 1.

In the insertion opening 17 thus formed, the first locking device 5 is arranged in the form of the pawl 13 between the two parts 14, 15. Likewise, a spacer 18 is provided of a plastic, which in the in Fig. 3 shown assembled state of the two parts 14, 15 respectively touching the upper part 15 and the lower part 14 abuts. In an alternative embodiment, the spacer element 18 is designed as a form-fitting shaping of one of the two parts 14, 15 and in such a way integrally with the relevant part 14, 15. In the in Fig. 3 shown assembled state of the two parts 14, 15, the parts 14, 15 are interconnected by two connecting means 19, wherein the one connecting means 19 is passed through the two parts 14 and the spacer element 18 and the other connecting means 19 through the two parts 14, 15th and the pawl 13 is passed for fixing the pawl and forming the pivot axis.

In the present case, the connecting means 19 are designed as screws with nuts, but it is also possible to use rivets or the like. In the spacer element 18 a blind hole-like bore is provided, in which a spring element 20 is held on one side. In the form-fitting formation of the spacer element 18 with one of the two parts 14, 15, the spring element 20 is preferably held by the part 14, 15, for example in a receiving opening formed by both parts 14, 15. The spring element 20 is configured here as a spiral spring and acts on the pawl 13 in such a way that the pawl 13 strives into its locking position. From the base body or the two parts 14, 15 protrudes a lever arm 21 of the pawl 13 through which the pawl 13 by operation by an operator in its open position, not shown, is pivotable.

If now the two buckles 1, 2 from the in Fig. 2 shown position for connecting the buckles 1, 2 are moved together in the respective connecting direction v, or even only one of the two buckles 1, 2 is moved in the direction of connection v, then first slide the two locking hooks 6, 8 with their retaining lugs 10 first into the respective insertion opening 17 of the respective other buckle 1, 2 in, guided by their respective guide surfaces 12. The retaining lugs 10 pivot the pawls 3, whereby the spring elements 20 compressed become. Upon further merging the respective undercuts 11 pass through the respective pawls 13, which engage under the influence of the spring bias of the respective spring elements 20 in the respective undercuts 11 and thus produce a positive connection between the locking devices 5, 7 and the respective locking hooks 6, 8.

In order to visually recognize that the locking or locking has taken place, the two locking hooks 6, 8 each have a first region 22 and a second region 23 adjoining thereto. The first area 22 is colored differently from the second area. In the in Fig. 2 As shown in the non-connected state of the buckles 1, 2, both the first region 22 and the second region 23 can be seen. In the in Fig. 1 However, only the second region 23 can be seen while the first region 22 with the different coloring is arranged completely within the respective insertion opening 17 or the respectively other buckle 1, 2. The majority of the connection extension 9 as well as the retaining lug 10 are part of the first area 22.

If now the in Fig. 1 shown connected belt buckles 1, 2 are acted upon train on the straps 3, then prevent each interlocked locking hooks 6, 8 and the locking means 7, 9 a release of the buckles 1, 2 from each other. Even with accidental operation of a single locking device 5, 7, ie by pressing the lever arm 21, there is still no release of the buckles 1, 2 from each other, since the respective other locking device 5, 7 further secures the buckles 1, 2 against unlocking. Only with simultaneous actuation of the lever arms 21 of the two locking devices 5, 7 unlocking or disengagement of the locking hooks 6, 8 takes place.

Fig. 5 to 7 show a buckle assembly according to another preferred embodiment of the invention. In this embodiment, the first buckle 1 and the second buckle 2 each also have a base body, which is formed of two symmetrically configured to each other parts 14, 15. Opposite in the Fig. 1 to 4 However, no separate spacer element 18 is provided as shown in FIG Fig. 4 shown. Instead, the spacer 18 is a form-fitting Forming one of the two parts 14, 15 and so integrally formed with the relevant part 14, 15 or molded. Accordingly, the spring element 20 is held in a receiving opening formed in the base body or is supported on the base body, as indicated by the reference numeral 18.
