Riveted connection for a button

The invention relates to the connection of a button with a carrier material, which also applies to the button in the riveted state Free movement in all directions is permitted, as is the case with a button fastened by sewing. In particular, the invention relates on a riveted connection for buttons that have a neck-like extension with an opening across the underside wear to the longitudinal axis of the extension, such as. B. eyelet buttons.

Knobs are already known which are attached to a carrier material by means of a riveting process. It's about Buttons with a rigid neck molded onto the button, the interior of which is intended to accommodate a neck that is inserted through the carrier material from below Rivet is formed. This rivet connection is inflexible and therefore not suitable for textiles. She is ugly and is possible because of the rigid connection between button and rivet nu.v difficult to button. In addition, the button part must withstand the rivet pressure.

To those buttons attached to a carrier material by means of rivets in their part lying on the visible side of the carrier material To keep them mobile, the button necks have been designed in the shape of a patrix in their lower part. The associated fastening part has a die-shaped opening for receiving the button neck male mold and carries at its other end staples or the like, which are inserted through the carrier material and in a counter-plate be riveted. With this type of attachment it is possible to first place the die part and the counter plate on the carrier material to rivet and then to anchor the actual button with its male part in the female part. They are disadvantageous many items that make the attachment of such a button to a carrier material expensive and complicate. Besides, the must Male head to achieve the greatest possible relative mobility be large and strongly undercut. The button neck receives thus a broad and clumsy appearance. S09884 / 0262

Another known version of a riveted button with movable button neck consists of a button, the neck of which as Hollow rivet is designed, the counterpart belonging to the button a use forms into which the button neck is inserted with a widening. If the button neck is long enough, the Free mobility in the longitudinal direction of the neck of the parts is detrimental to one another.

With these known means it has so far not been possible to create a textile-compatible, flexible rivet connection with an attractive appearance to accomplish. You also need for these known rivet fastenings many complicated individual parts in special shapes and sizes, which increases investment and storage costs will.

The object of the invention is to show a riveted connection for buttons that is just as textile-compatible and flexible as a sewing connection that can be easily made from just a few parts of a normal haberdashery range. The connection should allow mobility of the button in all directions.

This object is achieved according to the invention by connecting a button known per se, the underside of which is a neck-like one Extension with an opening transversely to the longitudinal axis of the extension carries, and one having at least one point Rivets. The interaction of the above-described opening in the button neck with the pointed rivet is particularly advantageous both during the fastening process and during use on the carrier material. In the device for producing the riveted connection, which is not the subject of this invention, the button can be tilted feed from above to the riveting point, while the pointed rivet with its back plate is guided in a horizontal position from below to the riveting point will. The rivet tip can now rip through the breakthrough and be bent in the direction of the back plate without the applied riveting pressure must be absorbed by the actual button part. Therefore, buttons made of metal can also be made of metal Plastic or the like can be riveted in this way. The button surface can be designed as desired, it can be, for. B. with

Fabric or be covered with a metal dome. The button bottom can e.g. B. instead of a button neck with a radial breakthrough also be designed as a known eyelet button.

The use of one known per se is particularly advantageous Two-point rivet, the two rivet tips of which then expediently reach through the opening in opposite directions and are bent around.

Riveting by means of a pointed rivet has the further advantage that the material threads are negligible when the carrier material is pierced can be damaged, whereby position changes can easily be carried out after incorrect riveting.

In the case of very fine fabrics, it is despite the use of a pointed rivet possible that fabric threads tear when piercing the rivet tip. To secure these damaged threads, one can click Apply an additional plate to the top of the fabric, the outer diameter of which appropriately corresponds to the back plate of the rivet and which has suitable openings for the rivet tip or tips to pass through. This plate would then be between The upper side of the carrier material and the button neck or button eyelet are so that the rivet tips are first the carrier material, then the plate and would then pierce the fastening opening of the button, after which they would then be bent back towards the platelet.

In the drawings are exemplary embodiments of the invention Riveted connection for an eyelet button shown. Fig. 1 shows the simple connection of a two-point rivet with a button. In Fig. 2, the connection using a two-point rivet and a plate for securing is possibly damaged threads shown.

It is a normal eyelet button made of metal, plastic or the like, as contained in a standard haberdashery assortment. The button surface can be designed as desired, there it does not have to take up any riveting pressure.

The two-pointed rivet is also part of a normal haberdashery range.

The plate 6 shown in Fig. 2 is zv / corner-shaped in his Outer diameter adapted to that of the back plate 3 of the rivet part. The plate 6 has openings in its plane, which in The arrangement and diameter correspond to the rivet tips 4 of the rivet part extending from the back plate 3, so that the rivet » pointed 4 can pass unhindered through the openings in the plate 6.

The rivet connection according to the invention shown for example in FIG. 2 is described in more detail below:

A rivet part lies with its back plate 3 against the underside of the carrier material 5. Two extend from the back plate 3 Rivet tips 4 which pierce the carrier material 5. On the upper side of the carrier material 5 is a plate 6, its openings allow the rivet tips 4 to pass through. The rivet tips 4 continue to engage in opposite directions through the opening of the eyelet 2 of the Button part and are then bent back in the direction of their back plate 3 or the plate 6.

With this connection it can be useful to adapt the bending radius of the rivet tips 4 to the cross section of the eyelet.

Of course, for the production of the invention Rivet connection, button shapes other than the eyelet button shown in the drawing can also be used. About the required mobility To achieve the button by the rivet connection according to the invention, the button only needs to be on its underside have a neck-like extension with an opening transverse to the longitudinal axis.

The advantageous rivet connection according to the invention can also be produced with normal carrier material without the plate 6, as FIG. 1 shows. «. _{A Ä}

Instead of a rivet part with two tips 4, a simple one can also be used Pointed rivets can be used with only one point.
