Description

Nürnberger Schere. Die Erfindung betrifft eine Verbesserung des unter dem Namen »Nürnberger Schere« bekannten Gelenkgliedersystems.Nuremberg scissors. The invention relates to an improvement of the under articulated link system known as the “Nuremberg Scissors”.

Es ist bekannt, die Nürnberger Schere mit verkürzten Endgliedern auszubilden, um bei kleinem Antriebswege einen großen Scherenausschlag zu erzielen. Abweichend von den bekannten Nürnberger Scherensystemen ist der Erfindung gemäß an die verkürzten Endglieder ein Scherengliederpaar gleicher Länge angelenkt, dessen Knotenpunkt fest gelagert ist, während am zweiten Knotenpunkt der Schere ein Handgriff angeordnet ist. Gleichzeitig sind an den obersten ,Scherengliedern in an sich bekannter Weise Sperrstifte vorgesehen, welche das vollständige Zusammenklappen der Scheren verhindern.It is known to train the Nuremberg scissors with shortened end links, in order to achieve a large scissor deflection with small drive paths. Different of the known Nuremberg scissors systems is the invention according to the shortened End links articulated a pair of scissor links of the same length, the junction of which is fixed is stored, while a handle is arranged at the second node of the scissors is. At the same time are on the top, scissor links in a known manner Locking pins are provided which prevent the scissors from fully collapsing.

Auf diese Weise wird der technische Fortschritt erreicht, daß trotz des kleinen Antriebsweges keine besonderen Hilfsmittel erforderlich sind, um die Schere zu bewegen, da bereits eine verhältnismäßig geringe Kraft zur öffnung der Schere ausreicht, wenn *die obenerwähnten Anschläge an den obersten Scherengliedern vorgesehen sind.In this way technical progress is achieved despite that the small drive path no special aids are required to the To move the scissors, as there is already a relatively small force to open the Scissors are sufficient if * the abovementioned stops on the uppermost scissor links are provided.

Die Erfindung ist in der Zeichnung veranschaulicht, und zwar zeigt Abb. i das Gelenkgliedersystem in geschlossenem Zustand, während Abb.2 eine Ansicht des Gelenkglieders3 stems von oben und Abb.3 in verkleinertem Maßstab im geöffneten Zustand darstellt. In den Abbildungen bedeutet d;, J . . . die Glieder eines Gelenkgliedersystems, die durch Scharniere b miteinander verbunden und über Knotenpunkte c geführt sind. Die Glieder a1 ünd a2 sind verkürzt, um den zwischen dem Fixpunkt cl einer Unterlage d und dem Knotenpunkt C2 liegenden Antriebsweg klein zu halten. Der Knotenpunkt c2 trägt einen Griff oder Hebel e, von dem aus die.- Bewegung des Gelenkgliedersystems hervorgerufen wird. An den letzten Gliedern a" und a2 des Gelenkgliedersystems sind zwei Anschläge, z. B. in Form von :Stiften f'-, f2, angebracht, welche die Aufgabe haben, ein vollständiges Zusammenklappen der letzten Gelenkglieder zu verhindern, und welche so angeordnet sein müssen; daß das Gelenkgliedersystem in seiner Bewegung nicht gestört wird.The invention is illustrated in the drawing, namely shows Fig. I the joint link system in the closed state, while Fig. 2 is a view of the joint member3 stems from above and Fig.3 on a reduced scale in the open State represents. In the figures, d ;, J. . . the links of an articulated link system, which are connected to one another by hinges b and guided via nodes c. The links a1 and a2 are shortened by the amount between the fixed point cl of a base d and to keep the drive path lying at node C2 small. The hub c2 carries a handle or lever e, from which the.- movement of the articulated link system is caused. On the last links a ″ and a2 of the articulated link system are two stops, e.g. B. in the form of: pins f'-, f2, attached which the task have to prevent the last joint links from completely collapsing, and which must be so arranged; that the articulated limb system in its movement is not disturbed.

Durch Verwendung -von Anschlägen, f i wird es trotz des kleinen Antriebsweges möglich, die am Griff e .ausgeübte Kraft derart zur Wirkung kommen zu lassen, daß sie sich, wie es zum öffnen des Gelenkgliedersystems erforderlich ist, durch alle Gelenkglieder a und über die Punkte b und c fortpflanzt, -während in vollständig zusammengeklapptem Zustand ein Spreizen der letzten Glieder nur möglich ist, wenn die am Griff e ausgeübte Kraft eine unverhältnismäßig große ist.By using stops, it becomes f i in spite of the small drive path possible to let the force exerted on the handle e. come into effect in such a way that as it is necessary to open the articular system, they go through all of them Joint links a and propagates over points b and c, -during in completely When folded, the last links can only be spread apart if the force exerted on the handle e is disproportionately large.
