Abstract

The nut (4) has a normal hexagonal head and a shaft with a left-hand male thread. It screws into the upper part (2) of a sleeve (1) with a left-hand female thread. The lower part (3) of the sleeve has a right-hand female thread engaging on a stud with a right-hand male thread. A projection (5) on the bottom of the screw engages on the flat top of the stud.

Description

Werkzeug zum Eindrehen von Stockschrauben, Gewindestangen u. ä.Tool for screwing in hanger bolts, threaded rods, etc.

Das Eindrehen von Stockschrauben, Gewindestangen u. ä. ist oft oft schwierig, da gegen den Widerstand des Einschraubgewindes ein hohes Drehmoment aufgewendet werden muß. Als Hilfsmittel können zwei Muttern dienen, die gegeneinander gekontert werden, was jedoch umständlich ist, da hier mit zwei Schraubenschlüsseln gearbeitet werden muß. Bei Stockschrauben befindet sich meist zwischen dem Holzschraubengewinde und dem metrischen Gewinde eine Schiüsself1äche. Sie ist für hohe Drehmomente zu schwach und bei tieferem Eindrehen nicht mehr erreichbar. Zudem ist an schlecht zugänglichen Stellen ein Arbeiten mit dem Maulschlüssel oft nicht möglich. Bekannte Eindrehwerkzeuge sind meist für speziellen Einsatz im Maschinenbau geschaffen und daher aufwendig in der Herstellung. Andere einfachere Werkzeuge, wie z. B. bei GM 80 17 587, sind noch zu kompliziert und eignen sich nur für Arbeiten an frei zugänglichen Stellen.Screwing in hanger bolts, threaded rods and the like is often difficult because a high torque must be applied against the resistance of the screw thread. Two nuts can be used as an aid, which are locked against each other, but this is cumbersome because two wrenches have to be used. Hanger bolts usually have a wrench flat between the wood screw thread and the metric thread. This is too weak for high torques and cannot be reached when screwing in deeper. In addition, it is often not possible to work with an open-end wrench in places that are difficult to access. Known screwing tools are usually designed for special use in mechanical engineering and are therefore expensive to manufacture. Other simpler tools, such as the GM 80 17 587, are still too complicated and are only suitable for working in freely accessible places.

Es stellt sich also die Aufgabe, ein Werkzeug zu schaffen, mit dem das Eindrehen von Stockschrauben und Gewindestangen, auch mit hohem Drehmoment, unter Vermeidung vorgenannter Nachteile möglich ist. Das Werkzeug muß einfach in Herstellung und Bedienung sein, damit es sich für den Einsatz sowohl im Handwerkerais auch im Heimwerkerbereich eignet.The task is therefore to create a tool with which it is possible to screw in hanger bolts and threaded rods, even with high torque, while avoiding the disadvantages mentioned above. The tool must be easy to manufacture and operate so that it is suitable for use by both tradesmen and DIY enthusiasts.

Die Aufgabe wird mit dem in den Schutzansprüchen 1-4 dargestellten Werkzeug gelöst.The problem is solved with the tool presented in claims 1-4.

Das Werkzeug wird lose bis zum Kontakt der Anschlagfläche mit der Stirnfläche des zu drehenden Bolzens auf diesen aufgeschraubt. Zum Eindrehen des Bolzens wird ein Schraubenschlüssel auf die Sechskant- Schiüsselfläche des Werkzeuges gesetzt und in Einschraubrichtung gedreht. Hierbei sperrt die Anschlagschraube durch das gegenläufige Linksgewinde das Werkzeug gegenüber dem Bolzen. Zum Abnehmen des Werkzeuges muß lediglich die Anschlagschraube durch leichte Rechtsdrehung gelockert werdenThe tool is loosely screwed onto the bolt until the stop surface comes into contact with the face of the bolt to be turned. To screw in the bolt, a wrench is placed on the hexagonal wrench surface of the tool and turned in the screwing direction. The stop screw locks the tool against the bolt with the counter-rotating left-hand thread. To remove the tool, simply loosen the stop screw by turning it slightly to the right.
