Abstract

The dowel has a thread retaining sleeve with a slit end. The spreading insert has a straight shank and a widened end, and is insrted shank first into the slit end of the sleeve. Striking the sleeve forces the slit end to spread over the insert and grip the sides of the bored hole. The straight shank has a snug fit inside the solid section of the sleeve. The upper end of the sleeve takes the fastener. ADVANTAGE - Secure grip in wall under tensile force.

Description

Spreizdübel, die aus einer Hülse und einem Keil oder Kegel bestehen sind bekannt.Expansion dowels consisting of a sleeve and a wedge or cone are known.

Die Erfindung macht sich zur Aufgabe einen Dübel zu schaffen, bei dem es ausgeschlossen ist, wird er auf Zug belastet, daß sich der Keil oder Kegel aus der Hülse löst. Bei allen bekannten derartigen Dübeln wird der Halt zwischen Hülse und Kegel oder Keil nur dadurch erzielt, indem der Keil oder Kegel im Bereich seiner Konizität mit der Hülse unter Formschluß steht, da der zylindrische Teil des Spreizkeils oder -kegels sich entweder nur im geschlitzten Bereich der Hülse bewegt, oder aber im anderen Fall, mit Spiel durch die Hülsenbohrung tritt. Die Er­ findung beruht darauf, daß der zylindrische Teil des Keils oder Kegels gleich oder größer im Durchmesser ist als die Bohrung der Dübelhülse im nicht zu spreizenden Bereich.The invention has the task of creating a dowel where it is excluded, he will be charged on train that the Wedge or cone releases from the sleeve. With all known such dowels the hold between the sleeve and the cone or wedge is only achieved by by placing the wedge or cone in the area of its taper with the sleeve is under positive locking, since the cylindrical part of the expansion wedge or -cone either moves only in the slotted area of the sleeve, or but in the other case, with play through the sleeve bore. The he The invention is based on the fact that the cylindrical part of the wedge or cone is equal to or larger in diameter than the bore of the dowel sleeve in the area not to be spread.

Der Flachkeil 1, welcher auch als Kegel ausgebildet sein kann, weist einen zylindrischen Teil 2 auf, dessen Durchmesser mindestens gleich oder aber größer ist als der Bohrungsdurchmesser 3 des Dübelkörpers 4. Beim Spreizvorgang des Dübels wird der Dübelkörper 4 mit seinem unteren Ende 5 über den zylindrischen Teil 2 des Keils oder Kegels 1 geschoben und in den ungeschlitzten Teil der Bohrung 3 des Körpers 4 gepreßt, wodurch eine feste Verbindung zwischen Keil oder Kegel und Hülse entsteht.The flat wedge 1 , which can also be designed as a cone, has a cylindrical part 2 , the diameter of which is at least equal to or larger than the bore diameter 3 of the dowel body 4 . During the expansion process of the dowel, the dowel body 4 is pushed with its lower end 5 over the cylindrical part 2 of the wedge or cone 1 and pressed into the unslotted part of the bore 3 of the body 4 , whereby a firm connection between the wedge or cone and sleeve is created.

Die Fig. III zeigt eine Ausführung des Dübels mit Innengewinde, dessen Ausbildung im übrigen dem gezeigten Außengewindedübel entspricht. FIG. III illustrates an embodiment of the anchor with an internal thread, corresponding to its formation in the rest of the outer thread anchor shown.
