innovation
The J3 ££ S3 £ $ BEg concerns a staple made from a single strip of spring band steel for holding together parts provided with an inlaid, unperforated, elastic sealing frame, in which the staple spring legs are wedge-shaped with a knife-shaped cutting edge. This formation of the knife-shaped cutting edge at the closing end of the spring legs enables the sealing frame to be perforated when the individual parts to be connected are brought together. ■ ''.

There are brackets known which are used to hold individual Find parts in connection with a pre-punched, elastic sealing frame. These brackets also have a clamping point below the head

that holds the parts together, with the clamp-spring legs taper downwards in a wedge shape in a closed bend.

Another embodiment of the clip corresponds essentially to the shape described above, but the end of the clip spring leg tip is not closed, but open, so that the individual spring legs can slide against each other when inserted into the connection point, thus making it easier to insert the clip Clamps are only used where all parts to be connected are prepunched to accommodate the clamp. An application of this bracket for parts that, for. Part are not prepunched is not possible because these clamps lack a device for the independent prepunching of certain parts when connecting all individual elements directly »

A bracket particularly suitable for the latter purpose

The staples according to the 3ESSBiZEaSMSgL represent an innovation.

This staple consists of a single piece of leather band steel, their individual spring legs below

of the head of the bracket straight and in a "certain Distance from each other run parallel as a clamping point for holding the to be fastened, with an inserted, unperforated, predominantly elastic sealing frame and the continuation the spring leg below the clamping point wedge-shaped downwards, but in such a way that - before the leather leg end is reached - the latter taper off parallel to a certain length, so that both spring legs close, open, but also closed side by side are guided in parallel, with the final end of each Peder leg in a knife-shaped The cutting edge runs out to perforate inserted, unperforated sealing frames.

This bracket has the advantage that it can be quickly and quickly integrated into a series of built-in elements of this type, such as B. for an inner door hood of refrigerators, can be used because of the time required for insertion the clamp is so small that assembly is difficult do not arise within the available work cycle of the conveyor belt.

Renewal-The way this gjgf jgdjj3ägsgemässen grooving clip works

is described using an exemplary embodiment, wherein

FIG. 1 shows, on an enlarged scale, the pricking clip in elevation;

Figure 2 represents this bracket voxi of the page;

Figure 5 shows the use of the clip within the parts to be fastened.

The staple 1 shown in FIGS. 1 and 2 is made from a strip of spring band steel and consists of a straight, flat or roof-shaped one Head 2 with subsequent spring legs J, 4, the below the head in a straight line at a certain distance from each other run parallel to one Clamping point 5 for holding the to be fastened, parts 8, 9 rear of the clamping point 5, the spring legs 3, 4 are wedge-shaped. Takes place before the end of the spring leg again to a certain length 6 an inwardly directed bend so that the spring legs 3 »4 · although close, not closed, run parallel next to one another, the closing end of each spring leg having a knife-shaped cutting edge 7.

Ra 122pg - 5 -

The knife-shaped cutting edge 7 is preferably under arranged at an angle of 60 °.

The installation conditions are shown in Figure 3, where the Staple 1 z. B. is used in an inner door hood of a refrigerator. Here 8 represents the metallic Housing of the refrigerator and with 9 is made mainly of a non-metallic material Inside door hood. The parts 8,9 are before they are placed on the assembly line - to the relevant fastening points pre-punched accordingly for the insertion of this bracket 1. As is well known a Refrigerator housing must be sealed against leakage of moisture to the outside, so must also be on this Place a seal using a sealing frame 10 made of a plastic material » This sealing frame 10 also serves at the same time to cover the assembled parts with one another.

The insertion of this predominantly consisting of a profile shape Sealing frame with pre-punched mounting holes caused difficulties on the assembly line because the exact insertion of the seal in relation to the

Ra 122pg - 6 -

punched mounting holes was very cumbersome. But by using a sealing frame 10 without perforated mounting holes will only become smoother The assembly process is made possible because one is now on the insertion a pre-punched sealing frame no longer needs to be considered. The perforation in the sealing frame 10 now took place directly during the assembly process by means of the staple 1 glue joining the parts 8, 9 among themselves. During the lancing process of the clip 1 is The seal slit open at this point of puncture and carried along with the clamp 1 pushed downwards into the mounting hole of the housing 8. This provided seal particles punched out of the seal 10 the insert hole in the housing 8 with a protective m «. whereby already pretreated housing 8, z. B. by enamelling, are not injured.
