Abstract

The bolt cutter has double brackets (1, 2) fixed for articulated movement on the cutter arms (A) of the bolt cutter. The double brackets are connected rotatable at the lower end and displaceable through eccentrics, oblong holes or spring pressure. When the cutters are closed the double brackets form an angle.

Description

Erklärungstatement

Handbetätigte Bolzenschneider sind bekannt.Hand operated bolt cutters are known.

Eine Kniehebelverbindung an den Handhaben ist gelenkbeweglich an den Messerschenkeln des Messerkopfes befestigt und überträgt die Muskelkraft auf die Messerschneiden.A Knee lever connection to the handle is articulated to the Knife legs of the knife head attached and transmits the muscle power to the Knife edges.

Die Maße des Kniehebels beträgt immer einige Millimeter mehr wie die Hälfte des Stichmaßes zwischen den Messerschenkelbohrungen bei geschlossenen Messerschneiden.The Dimensions of the Knee lever is always a few millimeters more like half the gauge between the knife leg holes with closed knife edges.

In der Endphase des Schneidvorgangs wird durch die Keilform der Schneiden das Material abgesprengt.In The final stage of the cutting process is determined by the wedge shape of the cutting edges the material blasted off.

Sinn der Erfindung ist, den Kraftaufwand beim Schneiden zu verringern.sense The invention is to reduce the effort when cutting.

Aufgabe der Erfindung ist die Verkleinerung des Stichmaßes, die den Einbau eines verkürzten Kniehebels mit größerer Hebelkraft ermöglicht.task The invention is the reduction of the gauge, the installation of a shortened bell crank with greater leverage allows.

Das wird erreicht durch zwei Doppellaschen gelenkbeweglich durch Bolzen an den Messerschenkeln befestigt.The is achieved by two double lugs articulated by bolts attached to the knife legs.

Am unteren Ende sind diese Laschen verstellbar durch Exenter, Langloch mit Radien usw. wie z.B. bei Wasserpumpenzangen verbunden. Bei geschlossenen Messerschneiden bilden die Doppellaschen einen Winkel zu den Messerschenkeln.At the lower end, these tabs are adjustable by Exenter, slot with radii, etc. such as e.g. connected to water pump pliers. When closed Knife cutting the double lugs form an angle to the knife legs.

Die Winkelform der Doppellaschen machen nun den Einbau eines verkürzten Kniehebels mit größerer Hebelwirkung in einem bestimmten Abstand zwischen der Verbindung mit den Messerschenkeln und der Verstellbarkeit am unteren Ende möglich.The Angle shape of the double lugs now make the installation of a shortened toggle lever with greater leverage at a certain distance between the connection with the knife legs and the adjustability at the bottom possible.

Die Maße der Doppellaschen ist abhängig von der Art und Größe der Bolzenschneider. Durch die Verstellbarkeit im Drehpunkt der Laschen kann auch das kleinere Stichmaß zwischen den Doppellaschen verändert werden. Der Kniehebel kann dadurch so eingestellt werden, dass seine höchste Druckstellung mit dem Punkt mit der Abspregung des Materials übereinstimmt, wodurch eine enorme Kraftersparnis entsteht.The Dimensions of Double lashing depends on the type and size of bolt cutters. Due to the adjustability in the pivot point of the tabs can also smaller gauge between changed the double lugs become. The toggle can thus be adjusted so that his highest pressure position coincides with the point with the Abspregung of the material, creating a enormous energy saving arises.

Eine Einstellung des Kniehebels durch Exenterschrauben mit den Doppellaschen ist ebenfalls möglich.A Adjustment of the knee lever by means of eccentric screws with the double lugs is also possible.

Die Verlagerung in die Laschen ergibt zusätzlich eine Verlängerung des Hebelarms zum Drehpunkt der Messerschneiden.The Displacement in the tabs additionally results in an extension of the lever arm to the pivot point of the knife edges.

FazitConclusion

  • 1. Doppellaschenverbindung machen einen verkürzten Kniehebeleinbau möglich1. Double link connection make a shortened toggle installation possible
  • 2. Verstellbarkeit auf den Absprengdruck2. adjustability to the Absprengdruck
  • 3. Verlängerung des Hebelarms3rd extension the lever arm
