Description

Steckschlüsselkopf. Der Gegenstand der Erfindung betrifft einen Steckschlüssel bzw. Steckschlüsselkopf, welcher das Lösen von versteckt liegenden Muttern erleichtern soll.Socket wrench head. The object of the invention relates to a socket wrench or socket wrench head, which make it easier to loosen hidden nuts target.

Bei vollständigen Maschinenaggregaten, besonders bei eingebauten Motoren in Kraftwagen oder Booten, sind häufig die Befestigungsschrauben einzelner Maschinenteile so unzugänglich, daß zum Lösen der Mutter erst einige andere Teile oder Umbauten abgenommen werden müssen, um die gebräuchlichen Schlüssel verwenden zu können. Dies hat, besonders in Reparaturwerkstätten, dazu geführt, daß man entweder Maulschlüssel verkürzt oder verbiegt und dann noch in langer geduldiger Arbeit die Mutter löst, was die an sich sonst einfache Reparatur wesentlich verteuert, oder daß man die Mutter einfach mit einem Meißel löst.With complete machine assemblies, especially with built-in motors In motor vehicles or boats, the fastening screws of individual machine parts are often so inaccessible that a few other parts or modifications have to be made to loosen the nut must be removed in order to be able to use the common keys. this has, especially in repair shops, led to the fact that you either have open-end wrenches shortens or bends and then loosens the mother in long patient work, which makes the otherwise simple repair much more expensive, or that the Nut simply loosens with a chisel.

Bei dem letzten, schnelleren Verfahren wird meistens, die Mutter und auch das Gewinde verletzt, was bei Spezialgewinde besonders unangenehm werden kann. Der neue Steckschlüssel ist gemäß der Erfindung derart ausgeführt, daß ein Lösen der Mutter durch Schlag möglich ist, ohne diese und das Gewinde zu verletzen. Der runde und im Innern einen der zu lösenden Muttern entsprechenden Hohlraum aufweisende Steckschlüsselkopf hat zu :diesem Zwecke außen nach den Sechskantseiten der Mutter hin oben sechs Nuten a (Abb. 2), welche auch seitlich bis, nach unten durchlaufen (a1, Schnitt Abb.3). Dies ermöglicht, daß man die Mutter sowohl schräg von oben (Abb. i) als auch von der Seite her losschlagen kann, wozu man sich eines Flachmeißels b bedient, dessen Schneide etwas abgerundet ist, wie auch die Nuten a und a1 in ihren Ecken nicht scharf, sondern abgerundet sind. Ein Schlag auf den in die Nuten a eingesetzten Meißel, also schräg von oben (Abb. i ) wird hauptsächlich durch die Unterlegscheibe bzw. den Maschinenteil aufgenommen und wirkt dadurch auf die Mutter nur lösend. Zu diesem Zweck ist auch der Schlüssel innen etwas höher als eine normale Mutter. Für den Fall, daß der Schraubenbolzen etwas länger als -die Mutter hoch ist, hat der Steckschlüsselkopf oben eine Bohrung c zum Durchtritt des Schraubenbolzens.In the latter, faster procedure, usually, the mother and also injures the thread, which can be particularly uncomfortable with special threads. The new socket wrench is designed according to the invention in such a way that that loosening of the nut by impact is possible without damaging it and the thread. The round and inside having one of the nuts to be loosened corresponding cavity Socket wrench head has to: this purpose outside to the hexagon sides of the nut towards the top six grooves a (Fig. 2), which also run laterally to the bottom (a1, section Fig.3). This enables the nut to be seen at an angle from above (Fig. I) as well as from the side, for which you can use a flat chisel b, the cutting edge of which is slightly rounded, as are the grooves a and a1 in their corners are not sharp, but rounded. One hit on the one in the grooves a chisel used, i.e. obliquely from above (Fig. i), is mainly through the Washer or the machine part added and thereby acts on the nut only releasing. For this purpose, the key is a little higher inside than a normal one Mother. In the event that the screw bolt is a little longer than the nut high is, the socket wrench head has a hole c at the top for the passage of the screw bolt.
