Description

Buckles System

The invention relates to a clamping buckle system consisting of at least one frame forming a clamping space and at least one clamping roller arranged inside the clamping space.

A chin strap for motorcycle protective helmets is known from DE 36 29 287 Cl, in which a self-adjusting, double-acting pinch roller fastener is described. In the event of a malfunction or the pinch roller lock being destroyed, it can only be replaced in a very complex manner. To do this, the entire restraint system must be removed from the helmet and the new pinch roller fastener sewn into the restraint belt system.

The object of the present invention is therefore to provide a generic clamping buckle system which is easy to assemble and can also be integrated into existing belt holding systems without the belt having to be removed from the actual holding systems when it is installed.

This object is achieved by the features of the main claim. Appropriate configurations of the clamping buckle system according to the invention are characterized in the dependent claims.

The object is achieved in that a clamping buckle system is provided, consisting of at least one frame forming a clamping space and at least one clamping roller arranged within the clamping space, the clamping roller being provided with releasable holding and / or guiding elements. It is advantageous that the frame of the clamping buckle there is at least two frame parts which are detachably connected together.

It is particularly advantageous that the frame parts of the clamping buckle according to the invention are U-shaped and consist of wire or tubular α material. It is also particularly advantageous that the frame parts consist of slotted and / or perforated band-shaped material.

Furthermore, it is advantageous that end spacers are detachably arranged between the frame parts.

It is also advantageous that the releasable holding and / or guiding elements have the form of pluggable bolts or eyes.

A further solution to the problem according to the invention is that a kit for a clamp buckle according to the invention is provided, comprising two frame parts, two end spacers which can be connected to the frame division to form a clamping space, at least one clamping roller and at least two holding and / or guide elements for each pinch roller, which can be fixed in the pinch roller and which can be arranged on the frame parts within the pinch space.

It is advantageous according to the invention that guide means are provided on the frame parts and that at least one pinch roller can be arranged to be movable within the clamping space and along the frame parts.

Furthermore, it is advantageous according to the invention that the frame parts of the kit according to the invention are U-shaped and consist of wire or raw material. It is equally preferred that the frame parts are made of slotted and / or perforated band-shaped material.

It is also advantageous according to the invention that the releasable holding and / or guiding elements of the kit according to the invention have the form of pluggable bolts or eyes.

According to the invention, it is particularly advantageous if the frame part is designed in one piece and the pinch roller can be divided along the longitudinal direction.

Another object of the present invention is a method for producing a clamping buckle using a kit according to the invention, in which a) first the holding and / or guiding elements are attached to the respective frame parts, b) then the end spacers and the clamping roller (s) defines the first frame part, c) furthermore fixes the holding and / or guiding elements of the second frame part on the clamping roller (s) and d) finally fastens the end spacer to the frame part.

The method according to the invention is particularly preferred if, after step b), the required belts, straps or holding means are placed around the end spacers and / or frame parts and / or clamping roller (s) in the predetermined manner and then continue with step c).

Finally, another object of the present invention is a clamping buckle obtainable by assembling a kit according to the invention using the method according to the invention. The clamp buckle according to the invention has the advantage that it can be easily installed in existing belt holding systems. The kit can also be used to easily replace defective clamping buckles. For this purpose, the belt as such does not have to be cut to expose the buckle from the holding system, nor does the buckle have to be destroyed in order to be able to replace it. The kit according to the invention also has the advantage that it consists of a few components, with some of the components, such as the end spacer and the pinch roller, being able to be identical without impairing the functionality of the entire clamping buckle. This leads to low manufacturing costs and simplified storage. It is also easily possible with the clamping buckle according to the invention and the kit according to the invention by slightly changing the clamping rollers and end spacer lengths to adapt the buckle to different belt widths without problems. This can also happen if the original belt width is not available, for example, by changing the belt system or by replacing a belt during a repair.

Exemplary embodiments of the clamping buckle according to the invention are shown with reference to FIGS. 1 to 7.

Show it:

1 is a perspective view of an exemplary embodiment of a clamping buckle according to the invention;

2 shows a top view of a holding and / or guiding element;

3 shows a top view of a frame part; Fig. 4 is a perspective view of a pinch roller; 5 shows a perspective view of a second exemplary embodiment of a clamping buckle according to the invention; Fig. 6 a further embodiment of a holding and / or guiding element;

7 shows a further embodiment of the clamping buckle according to the invention in a disassembled form; Fig. 8 a pinch roller that can be divided in the longitudinal direction;

Fig. 9 shows an embodiment of a frame part with a clamping space and a separable clamping roller; Fig. 10 shows a further embodiment of a frame part with three clamping spaces and three separable clamping rollers according to FIG. 8 and

Fig. 11 shows a third embodiment of a clamping buckle system with three clamping spaces and three separable clamping rollers according to FIG. 8th .

FIG. 1 shows a clip buckle 1 according to the invention, in which the frame parts 2 consist of a slotted and perforated band-shaped material. In this embodiment, the pinch rollers 4 are placed between the frame parts 2 and fixed to the frame part with the clamping bolts 6. Spacers 5 are arranged between the frame parts 2 at the respective ends of the frame parts. These end spacers 5 are firmly connected to the frame parts 2. For this purpose, the frame parts 2 have corresponding bores, through which in turn clamping bolts 6 are inserted, which engage in a bore in the end spacers 5. This arrangement ensures that the Klem roll 4 are movably arranged within the frame. The clamping space 3 formed from the frame parts 2 and the end spacers 5 can now be provided with the corresponding belts.

FIG. 2 shows a clamping bolt 6, which represents a holding and / or guiding element of the clamping buckle according to the invention in detail. In Figure 3, a frame part 2 is shown enlarged in supervision. It can clearly be seen that in this case this band-shaped material is perforated at the respective ends and slotted on the material lying in between.

Finally, FIG. 4 shows a pinch roller 4 in a perspective view. This cleram roller 4 can advantageously have a corrugation or a different roughening, so that the jamming on the belts is better guaranteed. A major advantage of the clamping buckle according to the invention is that this clamping roller can in principle also be used as an end spacer 5. The appropriate selection of the surface and the type of bore in the rollers can ensure that, in addition to the clamping rollers, the end spacers are also designed as rollers and are therefore movable and allow the belts to be carried out better.

Depending on the type and size of the straps, bands or other flat holding elements to be carried out by the buckle, a buckle of any dimensions can be produced by the choice of the length of the pinch roller 4 and the end spacers 5. A suitable choice of the length of the frame parts 2 also allows easy adjustment to the belts to be guided, held and / or clamped. Depending on the intended use, more than two pinch rollers can also be provided, as shown in FIG. 1. Depending on the task to be solved for the clamping buckle, a corresponding number of clamping rollers must be provided.

A further exemplary embodiment of the clamping buckle according to the invention is shown in FIG. Here, the frame part 21 is made of a U-shaped wire- CO IV) ro P>

5 comprises two frame parts 21 and two end spacers 5 according to FIG. 4 and, for each clamping roller 4 according to FIG. 4, two holding and guide eyes 61 according to FIG. 6.

The kits according to FIGS. 9, 10 and 11 consist of the central clamping space holder, which comprises the corresponding number of clamping spaces and a corresponding number of divisible clamping rollers. These pinch roller parts are then placed or placed on the pinch spaces and then attached to each other. ,

The proportions and dimensions given in the illustrated exemplary embodiments can be adapted to the respective circumstances. If such a clamping buckle according to the invention is mounted on a belt holding system, the corresponding parts are first preassembled without the second frame part already being added. The belt to be held is then around the exposed end spacers and clamping rollers

Tape or other flat holding material and only then the second frame part assembled. The disassembly of the clamping buckle takes place in the same way. For this purpose, the end spacers are detached from the frame part, after which the entire buckle is broken down into its individual parts and the belt strap can be removed without problems. Disassembly of the buckle is always necessary if, for example, the belts have to be replaced, as they have been worn or stretched. Due to the fact that the clamping buckle can be removed, a defective buckle can be easily replaced at any time without having to disassemble the belt system. The advantages of the clamping buckle according to the invention result from these facts. It is clear to the person skilled in the art that further embodiments of the clamping buckle according to the invention, which are adapted to the particular circumstances of the respective holding system, are likewise the subject of the invention. This includes, in particular, the type of surface design of the roller and spacers and the type of fixed or movable attachment of the rollers to the respective frame parts.

The production of such precision workpieces and the selection of the suitable materials, in particular the suitable metals and plastics, and their production techniques and processes are familiar to the person skilled in the art.
