Description

Das Patent 420282 hat eine Schere zum Gegenstand/bei welcher am Gestell angelenkte Lenker dazu dienen, die freien Kniehebelenden zu führen. Das bringt eine nicht unerhebliche Verwicklung in der Bauart der Schere mit sich, indem das Hebelgestänge aus einer außerordentlich großen Zahl von Schenkeln besteht. Nach der Erfindung soll die Bauart erheblich einfacher gestaltet werden, ohne daß die Wirkungsweise geändert wird. Das Hebelwerk setzt sich demnach nur noch aus fünf Schenkeln zusammen, während nach der Bauart des Hauptpatents sieben Schenkel erforderlich sind. Um das zu erreichen, ist die Kurbelstange in einem gemeinsamen Gelenk mit dem einen Schenkel des Kniehebels für die obere Schneidbacke und der Zugstange für die untere Schneidbacke verbunden, und das Kniegelenk des Kniehebels wird von einem LenkerThe subject of patent 420282 is a pair of scissors / which are hinged to the frame Handlebars serve to free the knee lever ends respectively. This brings with it a not inconsiderable involvement in the design of the scissors by the lever linkage from an extraordinarily large number of legs consists. According to the invention, the design should be made much simpler without the mode of action is changed. The lever mechanism is therefore only made up of five Legs together, while according to the design of the main patent, seven legs are required are. To achieve this, the connecting rod is in a common joint with the one leg of the toggle lever for the upper die and the pull rod for the lower cutting jaw connected, and the knee joint of the toggle lever is held by a handlebar

ao geführt, der vom Scherenständer getragen wird.ao, which is carried by the scissors stand.

In der Zeichnung ist die Erfindung wiedergegeben. The invention is shown in the drawing.

Mit der Kurbelstange α ist im Punkte b der Schenkel c des Kniehebels und die Zugstange d gemeinsam angelenkt. Der Schenkel c bildet mit dem Schenkel e ein Kniegelenk im Punkte /. Dieser Gelenkpunkt / steht unter der Führung des Lenkers g, der im Punkt h mit dem Scherengestell verbunden ist.With the connecting rod α , the leg c of the toggle lever and the pull rod d are articulated together at point b. The leg c forms with the leg e a knee joint in point /. This pivot point / is under the guidance of the link g, which is connected to the scissor frame at point h.
