Description

Druckhebellocher, dessen ortsfest gelagerter Handhebet unter Vermittlung eines gleichfalls ortsfest gelagerten winkelförmigen Hobels auf die Lochstempel zur Wirkung gelangt. Es sind bereits Druckhebellocher bekannt, bei denen die Kraftübertragung durch zwei ortsfest gelagerte Hebel erfolgt, von denen der eine als Winkel und der andere als Handhebel ausgebildet ist.Lever punch, whose stationary hand lift is mediated an angular plane, which is also fixedly mounted, on the punch comes into effect. There are already pressure lever punch known in which the power transmission takes place by two stationary levers, one of which as an angle and the other is designed as a hand lever.

Die Erfindung betrifft einen derartigen, sich durch eine besonders einfache Verbindung beider Hebel auszeichnenden Druckhebellocher, dessen Wesen darin besteht, daß der an seinem Scheitel gelagerte Übertragungshebel mit einem Schenkel in eine Ausnehmung des Handhebels eingreift, während der andere Schenkel auf die wie üblich geradlinig verschiebbaren Lochstempel wirkt.The invention relates to such a, by a particularly simple connection of both levers distinguishing pressure lever holes, its essence in it there is that the transmission lever mounted at its apex with one leg engages in a recess of the hand lever, while the other leg on the acts as usual rectilinearly displaceable punch.

Auf der Zeichnung ist ein derartiger Druckhebellocher in einer beispielsweisen Ausführungsform im Querschnitt dargestellt.In the drawing, such a pressure lever punch is exemplified Embodiment shown in cross section.

Der ortsfest gelagerte winkelförmige Übertragungshebel d und der Handhebel b haben in c bzw. in d ihre Drehpunkte. Der wagerechte Schenkel des Übertragungshebels a beeinflußt mittel- oder unmittelbar in üblicher Weise die geradlinig verschiebbarenLochstempel e, während der andere Schenkel des Hebels a in eine Ausnehmung des Handhebels b eingreift und sich gegen die Wandung der Ausnehmung so abstützt, daß der Übertragungshebel a beim Niederdrücken des Hebels b mitgenommen wird. Bei der gezeichneten Ausführungsform werden die beiden Hebel durch die unter Federwirkung stehenden Stempel e hochgehoben. Beim Lochen wird der Handhebel nach unten gedrückt, wobei schon bei schwachem Druck durch die Übersetzung des kleinen Hebelarmes von b und des großen Hebelarmes von a ein starker Druck auf die Stempel ausgeübt wird, welcher genügt, um selbst starke Pappe oder Papierstapel ohne Anstrengung zu durchlochen. Die punktiert gezeichnete Lage stellt die Druckkörper in ihrer unteren Endstellung dar.The fixed angular transmission lever d and the hand lever b have their pivot points in c and in d, respectively. The horizontal leg of the transfer lever a directly or indirectly influences the rectilinearly displaceable punch e, while the other leg of the lever a engages in a recess of the hand lever b and is supported against the wall of the recess so that the transfer lever a when the is depressed Lever b is taken. In the embodiment shown, the two levers are lifted up by the punches e under the action of a spring. When punching, the hand lever is pressed downwards, whereby even with slight pressure, the translation of the small lever arm from b and the large lever arm from a exerts a strong pressure on the stamp, which is sufficient to punch even thick cardboard or stacks of paper without effort . The dotted position represents the pressure hull in its lower end position.

PATENTANSPRUCH: Druckhebellocher, dessen ortsfest gelagerter Handhebel unter Vermittlung eines gleichfalls ortsfest gelagerten winkelförmigen Hebels auf die Lochstempel zur Wirkung gelangt, dadurch gekennzeichnet, daß der an seinem Scheitel gelagerte Übertragungshebel (a) mit einem Schenkel in eine Ausnehmung des Handhebels (b) eingreift, während der andere Schenkel auf die wie üblich geradlinig ver= schiebbaren Lochstempel (e) wirkt. PATENT CLAIM: Pressure lever punch, the stationary hand lever of which comes into effect with the mediation of a likewise stationary angular lever on the punch, characterized in that the transmission lever (a) supported at its apex engages with one leg in a recess of the hand lever (b), while the other leg acts on the punch (e), which can be moved in a straight line as usual.
