Description

Es sind bereits Zangen mit verstellbarer Maulweite bekannt, bei denen der eine Schenkel der Zange mit einem mit diesem aus einem Stück bestehenden zahnartigen Vorsprung versehen ist, der in Zahnlücken des anderen Schenkels eingreift. Der Drehzapfen derartiger Zangen. ist in den einen Zangenschenkel entweder eingeschraubt oder mit diesem verschweißt oder vernietet. Dies hat den Nachteil, daß sich der Drehzapfen durch den auf ihn beim Gebrauch der Zange mittels des verstellbaren Zangenschenkels ausgeübten Hebeldruck mit der Zeit lockert oder sogar abreißt, wodurch die Zange unbrauchbar wird.There are already pliers with adjustable jaw width known in which one leg of the pliers with a tooth-like one made of one piece with it Projection is provided which engages in tooth gaps of the other leg. The pivot such pliers. is either screwed into one of the pliers legs or with welded or riveted to this. This has the disadvantage that the pivot pin through the on him when using the pliers by means of the adjustable pliers legs exerted lever pressure loosens or even tears off over time, causing the pliers becomes unusable.

Diesen Nachteil zu beseitigen, ist der Zweck der Erfindung, die darin besteht, daß der aus einem Stück mit dem einen Zangenschenkel geschmiedete, in Zahnlücken des anderen Zangenschenkels eingreifende zahnartige Vorsprung gleichzeitig als Drehzapfen für den verstellbaren Zangenschenkel ausgebildet ist, der auch stärkster Beanspruchung standhält.To eliminate this disadvantage, the purpose of the invention is contained therein consists that the one forged from one piece with one pliers leg, in tooth gaps of the other pliers leg engaging tooth-like projection at the same time as a pivot is designed for the adjustable pliers leg, which is also subject to heavy use withstands.

In der Zeichnung ist die Zange in einer beispielsweisen Ausführung dargestellt. Abb. i zeigt die Zange in Ansicht, Abb. 2 den unteren Zangenschenkel in Ansicht und Abb. 3 den Zangenschenkel im Schnitt nach der Linie x-x der Abb. 2.In the drawing, the pliers are in an exemplary embodiment shown. Fig. I shows the forceps in view, Fig. 2 the lower forceps leg in view and Fig. 3 the pliers leg in section along the line x-x in Fig. 2.

Mit i ist der obere und mit 2 der untere Zangenschenkel bezeichnet. Der Zangenschenkel i ist mit einem länglichen Ausschnitt 4 versehen, der an der einen Längskante Zahnlücken 5 aufweist. Der Zangenschenkel i kommt mit dem Flusschnitt .; über den zahnartigen Vorsprung 3 des Zangenschenkels 2 auf diesen zu liegen. Mittels einer in den zahnartigen Vorsprung 3 eingeschraubten Schraube 8 mit hopf 7 und Unterlegscheibe 6 werden die Zangenschenkel 1. 2 zusammengehalten. Beim Gebrauch der Zange steht der obere Zangenschenkel i an dem unteren dadurch fest, daß dieser mit dem zahnartigen Vorsprung 3 in eine der Zahnlücken 5 des Zangenschenkels i eingreift.With i the upper and with 2 the lower pliers leg is designated. The pliers leg i is provided with an elongated cutout 4, which is on the has a longitudinal edge of tooth gaps 5. The pliers leg i comes with the river cut .; over the tooth-like projection 3 of the pliers leg 2 to lie on this. By means of a screw 8 screwed into the tooth-like projection 3 with hopf 7 and washer 6, the pliers legs 1. 2 are held together. When using of the pliers, the upper pliers leg i is fixed to the lower one by virtue of the fact that this engages with the tooth-like projection 3 in one of the tooth gaps 5 of the pliers leg i.
