DE2608907A1 - Apparel press button attachment element - made from springy material has retaining legs and holding plates - Google Patents

Abstract

Attachment element for plastic press buttons through which press buttons are fixed to their carrying material such as textiles or plastic materials without mechanical aids. The attachment (1) is made from springy material, reducing in cross section towards its edge (10) and is equipped with at least two retaining legs also sprung, extending to points (3) and fitted with cut outs below their points. The attachment element compensates for different strengths or thicknesses of materials used for the press button attachment and may be exchanged in the event of damage from exterior causes without destroying the holding plates (6a, 6b) by being detachable from their connection with them.

The invention relates to a Befesciguncselement for Plastic snap fasteners that allow it without mechanical Aids Push buttons only by hand on the carrier material, e.g. To attach textiles, plastics or the like.

Known are snap fasteners that are mechanically, e.g., by riveting, clawing, sewing or the like with the, ·, carrier material be attached.

However, the disadvantage here is that mechanical aids, such as attaching machines, attaching pliers or needle with thread, are required, which involves additional effort and also higher costs connected is.

It is also disadvantageous that when the carrier material is ironed, such snap fasteners are deformed, for example by the action of heat and are no longer functional, cannot be detached from the carrier material without destruction, and the carrier material as well can still be damaged.

The object of the invention is to provide a fastener of the initially to create mentioned type that does not have the disadvantages of the known plastic snap fasteners mentioned.

According to the invention, the object is achieved in that the Fastening element plate-shaped in cross section towards the edge is tapered resiliently and at least two tapering tips and provided with undercuts resilient locking legs having.

When applied by hand, the so-formed locking legs easily penetrate the carrier material, then slide with their tips into the recess of the holding plate, where they are resiliently compressed to the extent of the narrower opening of the recess and then spring up again with their undercuts after penetrating the recess snap into the correspondingly designed snap-in surfaces in the bottom of the snap-in plate, whereby a firmly adhering seat of the carrier material between the fastening element «.d H.lt.pl.tt.

The structural design is a particular advantage of the fastening element that various carrier material thicknesses can be compensated, since the resilient Adjust the plate to the respective material thickness after attachment and press it against the retaining plate (ball / eyelet), that an absolutely firm connection between the snap fastener and the carrier material is guaranteed.

Another advantage of fastening elements designed in this way is that they are damaged by external influences can easily be removed from the retaining plate by pressing the locking legs together and through a functional element have it replaced.

Another advantage is the space-saving, low installation height, which results from the fact that snap button halves can only be plugged together when the locking legs protruding with the tips in the bottom of the retaining plates (ball / eyelet) are offset from one another.

In the drawing, the invention is in an exemplary embodiment

shown and described below. It shows

Figure 1 fastener shown in perspective Figure 2 holding plate shown in perspective Figure 3 mounted push button shown in section.

The element 1 (FIG. 1) with the tips 3 of the resilient locking legs 2 is pushed through the carrier material 5 by hand during the attachment process and the recess 8 of the holding plate 6 (Figure 2) (ball or eyelet) pressed, where the locking legs 2 through the narrower recess 8 are inwardly resiliently compressed and after penetrating the recess 8 then resiliently with their undercuts 4 snap into the snap-in surfaces 9 correspondingly formed in the bottom 7 of the holding plate 6, as can be seen from FIG. The tapered cross-section edge Io of the element 1 is under spring tension on the carrier material 5, which after engaging the Detent legs 2 in the holding plate 6 a (eyelet) or 6 b (ball) between the holding plate 6 a, 6 b and element 1 is firmly clamped. The plate-shaped resilient design of the element 1 can With the available spring travel, various carrier material strengthens s are balanced without endangering the tight fit of the carrier material 5 between element 1 and retaining plate 6 a, 6 b.

In the case of damage from external influences, this is Element 1 can be easily dismantled without being destroyed. This is done by pressure on the Ausienflachen 11 of the tips 3 of the locking legs 2, whereby the locking legs 2 disengage from their fUstpü * 1t1on and the element 1 then through the recess 8 of the holding plate · f is finally printed out of the connection. The restoration the connection is then easily done by attaching a new, functional element 1 1n of the above described way.

As can still be seen from Figure 3, the retaining plate 6a (eyelet) and 6b (ball) can only be plugged together if the 1m bottom 7 with the tips 3 protruding locking legs Z are offset from one another, which in turn has the consequence that the Snap-fastener connections formed with such fastening elements are characterized by a low, space-saving structural height.
