  Drehsicherung eines über einen Teil seiner Länge geschlitzten Spreizdübels 
Die Erfindung betrifft eine Drehsicherung eines über einen Teil seiner Länge geschlitzten Spreiz- dübels in Eindrehrichtung der eingetriebenen Schraube, insbesondere für Durchsteckmontagen. 



   Wenn es sich um die Verbindung und gegenseitige Sicherung von dünnen Platten handelt, kommen
Spreizdübel zur Anwendung, die auf   verhältnismässig   kurzem Wege eine feste Verbindung durch erhöhte
Spreizwirkung beim Eintreiben einer Schraube gewährleisten. Ein Erfordernis dabei besteht darin, den
Spreizdübel gegen   eineverdrehung   zu sichern. Dies wird erfindungsgemäss dadurch erreicht, dass der Dü- bel einen Kopf besitzt, der als dünnwandiger, auf den Durchmesser des Dübelschaftes zusammendrückba- rer Konus ausgebildet ist. Eine Erhöhung der Sperrwirkung erfolgt dadurch, dass man den Konus an sei- nem Umfang mit einer Riffelung versieht, und die durch die Schlitze im Dübel gebildeten Zungen in ih- rem Querschnitt nach dem vorderen Dübelende zu erweitert.

   Zusätzlich können am Dübelumfang nach dem vorderen Dübelende zu verlaufende Sperrzungen angeordnet sein. Der Dübel besteht aus einem elastischen, zähen und alterungsbeständigen Kunststoff, der sich klemmend an die Dübellochwand an- presst. 



   Der Vorteil eines derartigen Dübels besteht darin, dass er nicht nur gegen ein Verdrehen gesichert ist, sondern dass die zu verbindenden Platten, besonders dann, wenn es sich   beispielsweiselum   Blechehandelt, nicht nur von der Dübelkopfseite her, sondern auch hinter dem Bohrloch durch die Spreizwirkung der im Querschnitt zunehmenden Dübelzungen gegeneinander gesichert sind. 



   Weitere Vorteile und Einzelheiten ergeben sich aus der Zeichnung. In dieser zeigt Fig. 1 eine Ansicht des Dübels, Fig. 2 einen Grundriss des Dübels in Pfeilrichtung A gesehen, Fig. 3 eine Ansicht des Dübels nach Durchstecken durch die Platten. 



   Der in Fig. 1 gezeigte Dübel besteht aus zwei oder mehreren durch Schlitze 1 gebildeten Zungen 2, die nach dem vorderen Dübelende in ihrem Querschnitt erweitert sind. Der Dübelkopf stellt einen aus einer dünnen Wand gebildeten Konus 3 dar, der an seinem Umfang mit einer Riffelung 3a versehen ist. Zu-   sätzlich können amDübelumfang noch zwei   oder mehrere nach dem Dübelkopf 3 zu verlaufende Sperrzungen 4 angeordnet sein. 



   Wird der Dübel in das gemeinsame Bohrloch 5 der Platten 6 und 7 gesteckt, so wird die dünne Wandung3 des aus einem elastischen, zähen Kunststoff bestehenden konischen Dübelkopfes zúsammengepresst und übt beim Eindrehen einer Schraube 8 in den Dübel auf dessen Anlagefläche 9 eine sperrende Wirkung aus. Eine zusätzliche Sperrwirkung gegen ein Verdrehen des Dübels wird dadurch erreicht, dass der Konus 3 an seinem Umfang mit einer Riffelung 3a versehen ist. 



   Handelt es sich bei den Platten 6 und 7 um Bleche, so würde die geriffelte konische Wand 3 des Dübelkopfes allein für die Drehsicherung des Dübels beim Eintreiben der Schraube 8 ausreichend sein. Um aber in diesem Falle auch auf der   dem Dübelkopf   abgewendeten Seite der Platten 6 und 7 eine die Sicherung der Platten erhöhende Spreizwirkung des Dübels zu erreichen, sind die durch Schlitze im Dübel gebildeten Längszungen 2 nach dem vorderen Dübelende zu in ihrem Querschnitt erweitert. Eine derartige Wirkung der Spreizungen unmittelbar hinter der Platte 7 ist aus Fig. 3 ersichtlich.

  Rotation lock of an expansion anchor slotted over part of its length
The invention relates to an anti-rotation device for an expansion anchor slotted over part of its length in the screwing direction of the driven screw, in particular for push-through assemblies.



   When it comes to connecting and securing thin panels together, come
Expansion dowels for use, which provide a fixed connection through a relatively short distance
Ensure expansion effect when driving in a screw. A requirement is that the
Secure expansion dowel against twisting. According to the invention, this is achieved in that the dowel has a head which is designed as a thin-walled cone which can be compressed to the diameter of the dowel shaft. The locking effect is increased by providing the cone with a corrugation on its circumference and widening the cross section of the tongues formed by the slots in the dowel towards the front end of the dowel.

   In addition, locking tongues can be arranged on the dowel circumference after the front dowel end. The dowel consists of an elastic, tough and non-aging plastic that is clamped against the wall of the dowel hole.



   The advantage of such a dowel is that it is not only secured against twisting, but also that the plates to be connected, especially when it comes to sheet metal, not only from the dowel head side, but also behind the drill hole through the expansion effect of the dowel tongues increasing in cross-section are secured against each other.



   Further advantages and details emerge from the drawing. 1 shows a view of the anchor, FIG. 2 shows a plan view of the anchor in the direction of arrow A, FIG. 3 shows a view of the anchor after it has been pushed through the plates.



   The dowel shown in Fig. 1 consists of two or more tongues 2 formed by slots 1, which are widened in cross-section towards the front end of the dowel. The dowel head represents a cone 3 formed from a thin wall, which is provided on its circumference with a corrugation 3a. In addition, two or more locking tongues 4 to run after the dowel head 3 can be arranged on the dowel circumference.



   If the dowel is inserted into the common borehole 5 of the plates 6 and 7, the thin wall3 of the conical dowel head made of an elastic, tough plastic is pressed together and exerts a locking effect on its contact surface 9 when a screw 8 is screwed into the dowel. An additional locking effect against twisting of the dowel is achieved in that the cone 3 is provided with a corrugation 3a on its circumference.



   If the plates 6 and 7 are metal sheets, the corrugated conical wall 3 of the dowel head alone would be sufficient for securing the dowel against rotation when the screw 8 is driven in. In this case, however, in order to achieve a spreading effect of the dowel on the side of the plates 6 and 7 facing away from the dowel head, the longitudinal tongues 2 formed by slots in the dowel are widened in their cross section after the front end of the dowel. Such an effect of the spreading immediately behind the plate 7 can be seen from FIG.
