Description
Rohrzange Es sind Rohrzangen bekannt, bei welchen ein in .einem U-förmig gestalteten äußeren Schenkel fest gelagerter Stützbolzen zwecks Einstellung der Rohrzange mit einer der in dem anderen im äußeren Schenkel geführten vollen Schenkel der Zange ausgebildeten Rasten, die mit ihren Öffnungen nach der Seite der Zangenbacken gerichtet sind und m einen in diesem inneren Zangenschenkel angebrachten Längsschlitz münden, zum Eingriff gebracht werden kann.Pipe wrench There are known pipe wrenches in which a U-shaped designed outer leg of fixed support bolts for the purpose of setting the Pipe wrench with one of the full legs guided in the other in the outer leg the pliers formed notches with their openings on the side of the pliers jaws are directed and m a longitudinal slot made in this inner pliers leg open up, can be brought into operation.
Die Erfindung betrifft eine Verbesserung dieser bekannten Rohrzangen und besteht darin, daß in dem Längsschlitz eine i#i dessen Enden festgeklemmte Flachfeder gelagert ist, welche sich federnd gegen die Mündungen der Rasten anlegt und letztere abschließt.The invention relates to an improvement of these known pipe wrenches and consists in that in the longitudinal slot a flat spring clamped at its ends is stored, which applies resiliently against the mouths of the catches and the latter concludes.
Hierdurch wird nicht nur ein leichtes und rasches Einstellen der Rohrzange ohne Entfernung des Stützbolzens ermöglicht, sondern hauptsächlich auch ein unbeabsichtigtes Austreten des eingestellten Stützbolzens aus der zugehörigen Rast verhütet.This not only enables the pipe wrench to be adjusted quickly and easily without removing the support bolt, but mainly an unintentional one Prevents the set support bolt from escaping from the associated detent.
Der Gegenstand der Erfindung ist auf der Zeichnung in Abb. i in einem Schnitt längs der Seitenfläche des vollen inneren Schenkels, in Abb.2 in Vorderansicht und in Abb.3 im Schnitt nach Linie I-I in Abb,. i veranschaulicht.The object of the invention is on the drawing in Fig. I in one Section along the side surface of the full inner leg, in Fig. 2 in front view and in Fig.3 in section along line I-I in Fig. i illustrated.
Wie bei den bekannten Rohrzangen ist i der im äußeren U-förmig gestalteten Zangenschenkel n festeingebaute Stützbolzen, der sich in eine der im inneren vollen Zangenschenkel 4 angebrachten Rasten 3 einlegt. Die Rasten münden in den Längsschlitz 5. Zwischen dem Rücken 21 das äußeren Zangenschenkels und dem inneren Zangenschenkel .4 ist ein Zwischenraum 7 belassen, der etwas größer als die Tiefe der Rasten 3 ist.As with the known pipe wrenches, i is the one in the outer U-shape Pliers legs n built-in support bolts, which are in one of the inside full Pliers legs 4 attached notches 3 inserts. The notches open into the longitudinal slot 5. Between the back 21, the outer pliers leg and the inner pliers leg .4 a gap 7 is left which is slightly larger than the depth of the notches 3 is.
Erfindungsgemäß ist in dem Längsschlitz 5 eine in dessen Enden festgeklemmte Flachfeder 6 gelagert.According to the invention, a clamped in the ends of the longitudinal slot 5 Flat spring 6 mounted.
Zwecks Einstellung der Rohrzange auf eine andere Maulweite wird durch Andrücken des äußeren Zangenschenkels 2 mit seinem Rükken 21 an den inneren Zangenschenkel q. der Stützbolzen i entgegen der Wirkung der Feder 6 aus seiner Rast 3 ausgehoben und dann der innere Zangenschenkel q. dem äußeren gegenüber verschoben, bis der Stützbolzen i vor eine gewünschte andere Rast 3 gelangt, in welche ihn die Feder 6 nach Freigabe des Zangenschenkels 2 hineindrückt.For the purpose of setting the pipe wrench to a different jaw width, Pressing the outer pliers leg 2 with its back 21 against the inner pliers leg q. the support bolt i lifted out of its detent 3 against the action of the spring 6 and then the inner pliers leg q. shifted to the outside until the Support bolt i arrives in front of a desired other detent 3, in which the spring him 6 pushes in after releasing the pliers arm 2.
