Description

Nüxnb-erger Scheren. werden bisher so ausgeführt, daß zwei Scherenarme in der Mitte miteinander drehbar verbunden werden und das anschließende Scherenpaar mit dem vorhergehenden Scherenpaar durch Eckgelenke verbunden wird. Die. Scherenarme liegen dabei im zusammengelegten Zustand übereinander, so daß. sie sperrig wirken.Nüxnb-erger scissors. have been designed so far that two scissor arms are rotatably connected to each other in the middle and the subsequent pair of scissors is connected to the previous pair of scissors by corner joints. The. Scissor arms lie on top of each other in the collapsed state, so that. they seem bulky.

Zweck der Erfindung ist es, diesen von allen Hebevorrichtungen fühlbaren Mangel zu beseitigen, so daß die Scherenarme im zusammengelegten Zustand der Schere nebeneinander in einer Ebene zu liegen kommen und ein sperriges Aufeinanderliegen der Scherenarme nicht auftritt.The purpose of the invention is to make this perceptible from all lifting devices To eliminate deficiency, so that the scissor arms in the collapsed state of the scissors come to lie next to each other in one plane and a bulky lying on top of each other the scissor arms does not occur.

In der Zeichnung sind mehrere Ausführungsbeispiele der Erfindung dargestellt. Es zeigt die Nürnberger Schere Fig. I von oben gesehen, Fig. II in zusammengelegtem Zustand von der Seite, Fig. III in halb offenem Zustand von der Seite, Fig. IV mit einem festen Fußpunkt in Seitenansicht, Fig. V mit zwei festen Fußpunkten in Seitenansicht, -Fig. VI als Scherengitter mit drei Fußpunkten. Nach Fig. I besteht jedes Scherenpaar aus zwei Scher-enarmhälfitenr i unid i' und, ein= -in einiem Stück idurrihliaufenden Scherenarm 2 von beliebigem Querschutt.Several exemplary embodiments of the invention are shown in the drawing. It shows the Nuremberg scissors Fig. I seen from above, Fig. II in a folded position State from the side, Fig. III in the half-open state from the side, Fig. IV with a fixed base in side view, Fig. V with two fixed base in side view, -Fig. VI as a concertina gate with three base points. According to Fig. I, there is each pair of scissors from two shear arm halves r i unid i 'and, a = -in one piece idurrihliaufenden Scissor arm 2 from any cross rubble.

Die Scherenarmhälften i und i' sind durch Bolzen, Niet, Schraube od: dgl. drehfest miteinander verbunden, während der durchlaufende Scherenarm 2 um das Mittelgelenk g bzw. h, zwischen den Scherenarmhälften i und i' liegend, drehbar gelagert ist. An den Eckgelenken c und d ist das nächste Scherenpaar angelenkt. Letzteres besteht aus den Scherenarmhälften 3; 3' und dem Scherenarm 4, der sich um den Scherenbolzen h dreht. Bei Punkt e und f kann ein weiteres Scherenpaar angeschlossen werden, was beliebig fortgesetzt werden kann.The scissor arm halves i and i 'are non-rotatably connected to one another by bolts, rivets, screws or the like, while the continuous scissor arm 2 is rotatably mounted around the central joint g or h, lying between the scissor arm halves i and i'. The next pair of scissors is hinged to the corner joints c and d. The latter consists of the scissor arm halves 3; 3 'and the scissor arm 4, which rotates around the scissor bolt h. At points e and f , another pair of scissors can be connected, which can be continued at will.

An den Eckgelenken der Scherenpaare sind, um den zum Einklappen benötigten Abstand zwischen den Scherenarmen zu gewährleisten, Distanzringe i und k angebracht, wie in Fig. I bei den Eckgelenken c und d ersichtlich. Im zusammengelegten Zustand kommen die Scherengelenke alle nebeneinander in eine Ebene zu liegen, wie Fig. II andeutet. Während Fig. IV eine Nürnberger Schere zeigt, bei welcher das erste Scherenpaar von einem Fußpunkt x ausgeht, werden nach Fig. V zwei feste Fußpunkte y und z vorgesehen.At the corner joints of the pair of scissors are necessary for folding To ensure distance between the scissor arms, spacer rings i and k attached, as can be seen in Fig. I at the corner joints c and d. When folded the scissor joints all come to lie next to each other in one plane, as in Fig. II indicates. While Fig. IV shows a pair of Nuremberg scissors, in which the first pair of scissors starting from a base point x, two fixed base points y and z are provided according to FIG.

Fig. VI zeigt eine nach Art eines Scherengitters ausgebildete Schere mit einem festen Fußpunkt w. Außerdem ist das Scherengitter noch in den Fußpunkten u und v angelenkt, welche sich längs einer durch den mittleren festen Fußpunkt laufenden Geraden verschieben können.VI shows a pair of scissors designed in the manner of a concertina gate with a fixed base w. In addition, the concertina gate is still in the base points u and v articulated, which run along a through the central fixed foot point Can move straight lines.
