Description

Device for avoiding unintentional adjustment

The present invention relates to a device for preventing inadvertent adjustment of a belt guided around at least one Gurtumlenksteg a buckle component. In the prior art various types of harnesses for a variety of applications are known. Thus, such arrangements of harnesses in the corresponding embodiment, e.g. used as a climbing harness or as a harness for various aviation sports but also when working on exposed areas to secure people. It is also known to use appropriately designed harnesses for securing and securing loads, just a few

To give examples. In order to be able to releasably connect the straps of the harnesses, it is known to use various types of buckles. The buckles usually have two or more buckle components, which can be detachably attached or fastened to one another via corresponding connecting devices and together form the buckle. The straps of harnesses are attached to the buckles often adjustable. For this purpose, there are a variety of embodiments in the prior art. If no adjustment of the belt is needed, the straps can be sewn tightly to the buckles. Often, however, it makes sense to provide an adjustment of the belt. In these cases, the straps are usually led around one or more Gurtumlenkstege a buckle component. In particular, in the latter embodiments often occurs the problem of unwanted adjustment of the belt tension, so in particular a loosening of the belt. Harnesses are rarely tightened by the user in the rarest cases. In general, the unwanted adjustment occurs at low tension or no tension on the belt when the user or the load moves. The result is that the straps must be re-tensioned frequently. In order to prevent accidental adjustment of the belt, generic devices are known per se in the prior art. Frequently Velcro tapes are used to prevent accidental adjustment. However, hook-and-loop tapes have the disadvantage that they slowly lose their functionality after repeated use.

The object is therefore to provide a generic device that is easy to use and durable reliable. This is achieved according to the invention, in that the device has a base body with a first contact surface and additionally at least one elastic body, preferably at least one spring tongue, with at least one further contact surface, wherein the elastic body, preferably with a region of the further spaced contact surface elastic body, is held directly or indirectly on the base body and the belt between the first contact surface and the other contact surface is clamped.

The device according to the invention makes it possible to clamp the belt, preferably one or two times one above the other, between the first contact surface of the main body and the further contact surface of the elastic body, whereby an unintentional adjustment of the belt is prevented, in particular even when it is not under tension. The elastic body may be formed, for example, as a spring, tongue or spring tab. It can be fastened or held directly on the base body. However, the elastic body can also be fastened or held indirectly on the main body with the interposition of another component. A significant advantage of the use of at least one elastic body is that a large range of belt thicknesses can be covered with a single device by the resilient action of the elastic body. As a rule, the device according to the invention is not a buckle component of a buckle but an additional component which is attached to the belt in addition to the buckle component and, as an additional part, an adjustment of the belt on the buckle. lenbauteil prevented. In this context, a buckle is understood to be a body consisting of two or more buckle components, wherein the buckle components can be detachably fastened to one another by means of corresponding connecting devices. Such buckles are known in the art in a variety of forms. Usually, a buckle member is attached to each of the straps to be joined, and the straps are then connected together by connecting the buckle members. The buckles serve in their interconnected state also to transfer tensile forces from one to the other belt.

In preferred embodiments of the device according to the invention, however, it is provided that the device according to the invention is provided exclusively for clamping the belt. It is conveniently free of other connecting devices. A device according to the invention is thus advantageously not a buckle component which is provided for connection to another buckle component. As a rule, devices according to the invention are therefore not intended to transmit tensile forces from one belt to another belt. Inventive devices can be designed in different widths and adapted to the respective width of the belt. But it is also possible to form a device according to the invention so that different width straps can be secured against accidental adjustment. In order to avoid slippage of the belt between the first contact surface and the second contact surface, it is advantageous if arranged on the first contact surface and / or the other contact surface, preferably in each case, a sequence of elevations, preferably knobs or webs, and between adjacent elevations Lowering for, preferably positive engagement, is arranged in the belt or are. As a result, the belt is held not only by the elastic forces of the elastic body but also by the engagement of the elevations in the belt. In order to enable a desired adjustment of the belt, for example when attaching or removing the harness, with the least possible forces, preferred embodiments of the invention provide that the device a, by means of a

Pivot axis pivotally mounted on the main body lever body, wherein the elastic body, preferably exclusively, is held on the lever body on the base body. In these cases, the elastic body is thus indirectly, namely held by the lever body on the base body. The lever body can be pivoted between a closed or clamping position and an open position about the pivot axis back and forth. In the open position, the adjustment of the belt with little effort is possible. In the closing or

Clamping position, the belt is clamped and secured against unintentional adjustment. Preferred embodiments of this type provide that the lever body, in addition to the pivot axis and / or spaced from the pivot axis arranged, at least one locking connection part which can be locked in a clamping position of the lever body with a counter-latching connection part of the base body. Due to the interaction of locking connection part and counter-locking connection part of the lever body is secured in the clamping position. If the lever body is to be pivoted into the open position, latching connection parts and counter-latching connection parts can be detached from one another. For this purpose, it is advantageous if the lever body and / or the base body has at least one manually operable release element for closing and / or releasing the latching connection between latching connection part and counter-latching connection part. As the releasing element, e.g. a be provided on the base body or on the lever body, preferably against an elastic restoring force, pivotally arranged release lever.

Preferred embodiments provide that the further contact surface of the elastic body is spaced less from the pivot axis than the catch connection part.

The lever body can be formed integrally with the pivot axis, locking connection part and elastic body. In terms of a simple retrofitting facilities according to the invention already attached to corresponding buckle straps belts preferred embodiments of the invention provide that the elastic body, preferably the lever body with the elastic body, by means of a tool-free closing and releasing connection, preferably latching connection, on Grundköper can be fastened , Particularly preferably, the pivot axis of the lever body by means of the tool-free closing and releasable connection, preferably latching connection, the Grundköper fastened. This makes it possible first to insert the belt into the base body and then to fasten the elastic body or the lever body to the base body. This avoids that the belt between the two contact surfaces must be threaded through. In this case, latching connections between the elastic body or the lever body and the main body are particularly preferred.

Preferred embodiments of the invention provide that the base body has or is a U-shaped profile, wherein the first contact surface is part of a lying between two protruding side legs of the U-shaped profile base portion of the U-shaped profile. In such embodiments, it can be provided that the counter-locking connection parts and / or the receptacles for the pivot axis of the lever body are arranged on the side legs.

In addition to the device itself, the invention also relates to an arrangement with at least one buckle component, which has at least one connecting device for releasably connecting with another buckle component, and with at least one belt which is guided around at least one Gurtumlenksteg the buckle component, wherein the arrangement additionally at least has a device according to the invention and at least a first portion of the belt and at least one further portion of the belt between the first bearing surface and the further contact surface are clamped. In this context, favorable embodiments provide that the sections of the belt with their, from The contact surfaces, on which they each lie directly against, facing away from each other in the area between the contact surfaces directly on each other.

Further features and details of preferred embodiments of the invention will be explained with reference to an exemplary embodiment according to the invention shown in the figures. Show it:

Fig. 1 to 3 different views of an arrangement of buckle, belt and inventive device, wherein the device according to the invention is in the closed or clamping position;

Figures 4 to 6 to Figures 1 to 3 corresponding representations, but wherein the device is in the open position.

Fig. 7 to 10 different representations of the device according to the invention used in Figures 1 to 6 per se;

Fig. 1 1 is a perspective view of the main body of this embodiment and

FIGS. 12 and 13 representations of the lever body of this embodiment.

1 shows in a perspective view how two known buckle components 3 and 3 'are connected to one another by means of a corresponding connection device 10 and 10'. FIG. 2 shows a longitudinal section through the situation according to FIG. 1 and FIG. 3 shows the corresponding side views. In the exemplary embodiment shown, a connecting device 10 in the form of a male extension is formed on the buckle component 3. The other buckle component 3 'has, as corresponding counterparts, connecting devices 10' in the form of locking levers. By means of the locking lever 10 ', the connecting device 10 is fixed, so that the two buckle components 3' and 3 are firmly connected to each other and tensile forces on the belt 4 on the buckle components 3 and 3 'on a not shown here, on the buckle part 3' attached belt or other object can be transferred. To release the two belts from each other, the locking levers of the connecting device 10 'are operated by hand, so that the two buckle components 3 and 3' can be separated from each other. All this is on known and can be performed according to the prior art in a variety of embodiments. In order to be able to adjust the length of the harness, the belt 4 actually shown is guided around the Gurtumlenksteg 2 on the buckle part 3. As a rule, the Gurtumlenkstege 2 are slidably mounted on the buckle component 3, so that the guided around the Gurtumlenksteg belt 4 is held by means of Gurtumlenksteg 2 on the buckle member 3 by clamping. However, this clamping action is usually only as long as long as appropriate train on at least one of the sections 20 or 21 of the belt 4 is present. The initially described problem with the unintentional adjustment of the length of the belt 4 always occurs when the belt 4 or its sections 20 and 21 are not subjected to a corresponding train. Then the belt 4 can slip around the Gurtumlenksteg 2 and thus give the unwanted adjustment. In order to prevent this, a device 1 according to the invention is now provided, which is arranged on the belt 4 in addition to the buckle component 3. The device according to the invention makes it possible to clamp the belt 4 between the first contact surface 6 of the main body 5 and the further contact surface 8 of the elastic body 7, so that an unintentional adjustment of the belt 4 can no longer occur.

In FIGS. 1 to 3, the device 1 is in its clamping or closing position, in which the belt 4 is in the manner described against an undesired one

Adjustment is secured. 4 to 6, the device 1 is in the open position, in which the belt 4 is not clamped in the device 1 and so, if desired, a desired adjustment can be performed. FIGS. 4 to 6 again show a perspective view, a longitudinal section and a side view. In Fig. 7, the device 1 is shown without strap 4 and without a buckle in the open position. Fig. 8 shows a side view of the device 1 in the clamping or closed position. In Fig. 1 1, the main body 5 of the device 1 is shown detached from the other components. FIGS. 12 and 13 show the lever body 14 detached from other representations. Fig. 12 shows a side view, Fig. 13 is a perspective view from below. In the illustrated embodiment, the elastic body 7 is formed as a spring tongue or elastic clamping strap. He is not directly but indirectly held on the lever body 14 on the base body 5. Of course, other embodiments of the invention are conceivable, for example, in which the elastic body 7 is attached directly to the base body 5. The elastic body 7 has the further contact surface 8. On the main body 5, the first contact surface 6 is provided as a counterpart. In the clamping position, the belt 4 is clamped between the first contact surface 6 and the further contact surface 8. In the sense of the most effective clamping effect, both the first contact surface 6 and the further contact surface 8 are each equipped with a succession of elevations 11 and depressions 12 arranged between adjacent elevations 11 in the exemplary embodiment shown. In the example shown, the elevations 11 are nubs. Instead, however, webs or the like can be used. In the exemplary embodiment shown, the elastic body 7 is fastened to the lever body 14 by the area 9 opposite the further contact surface 8. In the illustrated variant, the lever body 14 is integrally formed. That is, the pivot axis 13, the release elements 17, the locking connection parts 15 and the elastic body 7 are integrally connected to each other. Such parts can be made of plastic, for example by injection molding. Also, the main body 5 may be formed of plastic accordingly. But there are also other materials such as metal conceivable in both parts. The lever body 14 is equipped in the illustrated embodiment with axle bolts, which form the pivot axis 13. The pivot axis 13 or the aforementioned axle bolts are pivotally mounted in a corresponding recess of the base body 18.

As already mentioned, it makes sense in terms of a simple retrofitting when the axle bolt or the pivot axis 13 are non-destructive in the corresponding pivot axis of the main body 5 and latched are stored or is. In the fully assembled position shown, in any case, the lever body 14 can be pivoted about the pivot axis 13 with respect to the base body 5 between the open position and the clamping or closed position. In order to secure the lever body 14 in the clamping or closed position, in the illustrated embodiment an additional locking connection between the pivotable lever body and Grundköper 5 is provided. This is formed by the latching connection parts 15 of the lever body 14 and the counter-latching connection parts 16 of the main body 5. In the exemplary embodiment shown, the latching connection parts 15 are front latching lugs and the counter latching connection parts 16 are corresponding recesses for receiving these latching lugs in the side limbs 18 of the base body 5. However, this need not necessarily be so. Corresponding locking connections can of course also be designed differently. In order to allow the most favorable leverage forces to act, it is preferably provided that the further contact surface 8 is closer to the pivot axis 13 than the catch connection parts 15. In order to be able to release the latching connection between latching connection part 15 and counter-latching connection part 16 and, if appropriate, also be able to close it provided on the lever body 14 of this embodiment manually operable release elements 17. In the illustrated embodiment, these are designed as against a resilient restoring force pivotally mounted release lever. FIG. 9 shows the pivoted-out position of these release elements 17, in which the latching connection parts 15 are released from the counter-latching connection parts 16. In this position, the lever body from the clamping or closed position shown in FIG. 8 in the open position shown in FIG. 7 are pivoted. When pivoting back from the open position into the clamping position, the latching connection parts 15 favorably snap on their own into the counter-latching connection parts 16 as soon as the lever body 14 is pivoted correspondingly far to the base body 15. 10 shows a representation in which the latching connection parts 15 are latched into the counter-latching connection parts 16. In Fig. 1 1 is particularly easy to see that the main body 5 of this embodiment is formed as a U-shaped profile. On the base portion 19 of this U-shaped profile is the first contact surface 6 with the elevations 1 1 and 12 sinks. In the two of the central base portion 19 projecting side legs 18, the counter-locking connection parts 16 and the axle mounts for the pivot axis 13 are arranged. L egende to the reference numbers
