Description

Aus einem Blechstreifen hergestellter iWauerdiibel mit an einem eingerollten Schaft sitzender Schelle o. dgl. Die Erfindung betrifft einen aus einem Blechstreifen hergestellten Mauerdübel mit an einem eingerollten Schaft sitzender Schelle. Das Neue liegt darin, daß gegen den zylindrisch eingerollten Schaft .ein winklig abgebogener Teil des Blechstreifens unter Bildung einer Schlagfläche für das Eintreiben ;des Dübels angelegt ist. Die zylindrische Einrollung gibt denn Dübel in dem vorgebohrten Loch in der Wand einen federnden festen Halt und gestattet ein Richten der Schelle durch Drehung, was bei einer Einrollung mit Kantenbildung nicht möglich ist, da die Kanten das Drehen verhindern. Die zylindrische Einrollung kann sich nach unten verjüngen. Auch ist -es vorteilhaft, den Schaft zur Erhöhung der Haftfestigkeit in der Wand stellenweise aufzuweisen. Der winklig abgebogene Teil verstärkt den Dübel und erleichtert das Eintreiben.IWauerdiibel made from a sheet of sheet metal with one rolled up Shank of seated clamp or the like. The invention relates to a sheet metal strip manufactured wall dowel with a clamp seated on a rolled shaft. That What is new is that it is bent at an angle against the cylindrically rolled shaft Part of the sheet metal strip forming a striking surface for driving in; des Dowel is applied. The cylindrical curl gives the dowel in the pre-drilled one Hole in the wall provides a resilient, firm hold and allows the clamp to be straightened by rotation, which is not possible with a curling with edge formation, there the edges prevent it from turning. The cylindrical curl can turn down rejuvenate. It is also advantageous to use the shaft to increase the adhesive strength to be shown in places in the wall. The bent part reinforces the Dowels and makes driving in easier.

Auf der Zeichnung ist ein Ausführungsbei4-piel des neuen Dübels dargestellt, und zwar in der Abb. i in der Seitenansicht, und in der Abb. 2 in der Draufsicht.The drawing shows an exemplary embodiment of the new dowel, namely in Fig. i in side view, and in Fig. 2 in plan view.

Der zylindrisch eingerollte Schaft a hat eine Verjüngung 4. und setzt sich an der anderen Seite in den winklig abgebogenen Teil 3, der die Schlagläcbe bildet, fort. An dem Teil, sitzt die Schelle r. Die Einrollnaht ist in Abb. a zu erkennen.The cylindrically rolled shaft a has a taper 4. and continues on the other side in the angled part 3, which forms the impact face. The clamp sits on the part. The rolled-in seam can be seen in Fig. A.
