Description
Mauerdübel Die vorliegende Erfindung betrifft einen Mauer dübel, der sich gemäss der Erfindung von bekannten Ausführungen dadurch unterscheidet, dass er federnde, in das Mauerwerk einzutreibende, im Querschnitt U- Form besitzende Zungen aufweist, die durch Eintrei ben einer Schraube gespreizt werden können.
Die beiliegende Zeichnung veranschaulicht ein Ausführungsbeispiel des Erfindungsgegenstandes. Darin zeigt: Fig. 1 eine Ansicht in Richtung des Pfeils P in Fig. 2, Fig.2 einen Schnitt nach der Linie 11-I1 in Fig. 1 und Fig. 3 eine Draufsicht zu Fig. 2.
Der im wesentlichen die Form einer zylindri schen Hülse 1 aufweisende gezeichnete Mauerdübel besitzt an seinem unteren Ende vier federnde Zungen 2, die im Querschnitt die Form eines U besitzen und zwischen welchen Schlitze 3 vorhanden sind. Am oberen Ende ist die Hülse 1 mit einem Gewinde 4 ausgerüstet. Beim Gebrauch wird der Mauerdübel in ein vorgebohrtes, dem Aussendurchmesser des Dübels entsprechendes Loch eingeschoben. Dabei ist der Dübel bereits mit einer Schraube versehen, welche ein Stück weit in das Gewinde 4 eingeschraubt ist. Beim weiteren Eintreiben der Schraube werden die Zungen 2 des Dübels gespreizt und deren Schenkel 2' dadurch in das Mauerwerk getrieben. Dies gewähr leistet eine feste Sicherung des Dübels gegen Drehung und gewaltsames Herausziehen.
Der Mauerdübel kann auch eine andere Anzahl von Zungen aufweisen als in der Zeichnung darge stellt. Der beschriebene Mauerdübel kann durch Stan zen und anschliessendes Rollen hergestellt werden. Die dabei aneinanderstossenden Kanten 5 des zylindri schen Endes können miteinander verschweisst werden, was aber nicht unbedingt erforderlich ist.
Wall dowel The present invention relates to a wall dowel which, according to the invention, differs from known designs in that it has resilient, U-shaped cross-section tongues which are to be driven into the masonry and which can be spread apart by driving a screw.
The accompanying drawing illustrates an embodiment of the subject matter of the invention. 1 shows a view in the direction of the arrow P in FIG. 2, FIG. 2 shows a section along the line 11-I1 in FIG. 1 and FIG. 3 shows a plan view of FIG.
The substantially the shape of a cylindri's sleeve 1 having drawn wall plug has at its lower end four resilient tongues 2 which have the shape of a U in cross section and between which slots 3 are present. At the upper end, the sleeve 1 is equipped with a thread 4. During use, the wall plug is pushed into a pre-drilled hole that corresponds to the outside diameter of the plug. The dowel is already provided with a screw which is screwed a little into the thread 4. When the screw is driven in further, the tongues 2 of the dowel are spread apart and their legs 2 'are thereby driven into the masonry. This ensures that the anchor is firmly secured against rotation and forceful pulling out.
The wall plug can also have a different number of tongues than in the drawing Darge presents. The wall anchor described can be produced by Stan zen and then rolling. The abutting edges 5 of the cylindri's end can be welded together, but this is not absolutely necessary.
