Abstract

A pair of handles (3,4) is individually connected to pair of shearing blades (1,2). A pin (9), provided at the base (10,11) of each shearing blade, is inserted through a slot (12) formed at each handle, making the connection (5,6) between the blade and handle adjustable. Each pin is locked into a notch (8) at one end of each slot, making the blade pivotal relative to the handle.

Description

Die Erfindung bezieht sich auf eine Schere mit zwei Scherenblättern und zwei zugeordneten Handhaben durch verstellbare Einstellungen in den Handhaben.The invention relates to a Scissors with two blades and two assigned handles through adjustable settings in the handling.

Handbetätigte Scheren mit Hebelübersetzung sind bekannt.Manually operated scissors with lever transmission are known.

Art der Endung ist diese gebrauchsvorteilhaft weiterzubilden.The type of extension is to be further developed in a manner that is advantageous for use.

Diese Aufgabe besteht darin, den Druck an den Scherenschneiden zu erhöhen um auch stärkere Bleche leichter schneiden zu können.This objective is to increase the pressure on the scissor blades to leche to even stronger B easier to cut.

Die Schere mit zwei Scherenblättern (1 + 2) ist mit den beiden Handhaben (3 + 4) gelenkbeweglich befestigt. Die beiden Handhaben (3 + 4) sind in einem Abstand von der gelenkbeweglichen Verbindung (5 + 6) in einem Drehpunkt (7) verbunden, wodurch eine Hebelwirkung entsteht.The scissors with two scissor blades ( 1 + 2 ) is with the two handles ( 3 + 4 ) articulated attached. The two handles ( 3 + 4 ) are at a distance from the articulated connection ( 5 + 6 ) at a pivot point ( 7 ) connected, which creates a leverage effect.

Die Aufgabe der Erfindung besteht darin, durch Verkürzung der Gelenkverbindung (5 + 6) in den Handhaben (3 + 4) zum Drehpunkt (7) hin, die Hebelwirkung zu erhöhen. Dadurch wird der Druck an den Scherenschneiden (1 + 2) verstärkt ohne den Druck an den Handhaben (3 + 4) zu ändern, der durch die Kraft der Hand begrenzt ist.The object of the invention is to shorten the joint connection ( 5 + 6 ) in the handling ( 3 + 4 ) to the fulcrum ( 7 ) to increase leverage. This will reduce the pressure on the scissor blades ( 1 + 2 ) reinforced without the pressure on the handles ( 3 + 4 ) which is limited by the strength of the hand.

Die Verkürzung in den Handhaben (3 + 4) wird durch Aussparungen in Form von Radien (8) oder Kerben zum Einrasten der gelenkbeweglichen Bolzen (9) zwischen Scherenschenkeln (10 + 11) und den Handhaben (3 + 4) erreicht.The shortening in the handling ( 3 + 4 ) is provided by recesses in the form of radii ( 8th ) or notches for engaging the articulated bolts ( 9 ) between scissor legs ( 10 + 11 ) and the handling ( 3 + 4 ) reached.

Durch eine Verbindung mit einem Langloch (12) wird eine Schnelleinstellung erzielt.By connecting to an elongated hole ( 12 ) a quick adjustment is achieved.

Die im Drehpunkt (7) der Handhabe (3 + 4) befindliche Feder hält die Schenkelbolzen (9) in der eingestellten Aussparung fest.At the pivot ( 7 ) the handle ( 3 + 4 ) located spring holds the leg bolts ( 9 ) in the set recess.

Die Gegenstände der Erfindung sind zeichnerisch veranschaulicht.The objects of the invention are illustrative illustrated.
