Description

Die Erfindung betrifft einen Gelenkarm mit umhüllter Paraileiogrammfunktion, wobei das Gehäuse mit Gelenkachsen ausgestattet istThe invention relates to an articulated arm with a covered Paraileiogrammfunktion, with the housing with Articulated axes is equipped

Ein derartiger Gelenkarm, von dem die Erfindung ausgeht, ist aus der DE-PS 8 64 223 bekanntSuch an articulated arm, from which the invention is based, is known from DE-PS 8 64 223

Letzere offenbart eine Vorrichtung zur Parallelführung eines Gerätes, wie zum Beispiel eines Zeichenkopfes mit einem oder mehreren hintereinander geschalteten Führungsarmen, wobei die Parallelführung mit Hilfe von Kreis- oder Kreissegmentscheiben erfolgt, die in den Enden der Führungsarme drehbar gelagert sind und durch Wälzkörper kraft- oder formschlüssig derart miteinander verbunden sind, daß beim Verschwenken eines Armes um die im Schwenkpunkt feststehende Kreis- oder K.reissegmentscheibe -Wen Relativbewegung gegenüber dem Lenker gleichsinnig auf die am anderen Lenkerende angeordnete, gegebenenfalls das zu führende Gerät aufnehmende Kreis- oder Kreissegmentscheibe übertragen wird.The latter discloses a device for parallel guidance of a device, such as a drawing head with one or more guide arms connected one behind the other, the parallel guidance being carried out with the aid of circular or circular segment disks which are rotatably mounted in the ends of the guide arms and are non-positively or positively locked by rolling elements are connected to each other in such a way that when an arm is pivoted around the circular or circular segment disk fixed at the pivot point, relative movement with respect to the handlebar is transmitted in the same direction to the circular or circular segment disk which is arranged at the other end of the handlebar and which may be used to accommodate the device to be guided.

Dabei sind alle Glieder in Gehäusen angeordnet. Bei dieser Vorrichtung ist zwar die bei ferner bekannten Parallelogrammführungen (Lenkerführungen) sind ergebende Verletzungsgefahr durch die beim Verschwecken des Gelenkarmes sich einander nähernden Lenker ausgeschlossen, aber ihre Herstellung ist relativ kompliziert und teuer.All links are arranged in housings. In this device, although that is also known in the case of Parallelogram guides (handlebar guides) are a resulting risk of injury from being swallowed up of the articulated arm, approaching handlebars are excluded, but their manufacture is relative complicated and expensive.

Aufgabe der Erfindung ist es nun, einen Gelenkarm der im Oberbegriff des Anspruches 1 angegebenen Art derart zu verbessern, daß unter Beibehaltung des beim Stand der Technik bereits erreichten Vorteiles, nämlich daß eine Verletzungsgefahr weitgehend ausgeschlossen ist, darüber hinaus eine Vereinfachung des Gelenkarmes erreichbar ist, die auch eine preiswertere Herstellung ergibt.The object of the invention is now to provide an articulated arm of the type specified in the preamble of claim 1 to be improved in such a way that while maintaining the advantage already achieved in the prior art, namely that a risk of injury is largely excluded, in addition, a simplification of the articulated arm is achievable, which also results in a cheaper production.

Die Lösung dieser Aufgabe ist dadurch gekennzeichnet, daß die Gehäuseschalen als Lenker zwischen den Gelenkachsen ausgebildet sind und daß für die Paraileiogrammfunktion ein einziges Schienenpaar zwischen den Gehäuseschalen vorgesehen ist daß exzentrisch an auf den Gelenkachsen angeordneten Gelenkscheiben angreiftThe solution to this problem is characterized in that the housing shells as a link between the Joint axes are formed and that a single pair of rails for the Paraileiogrammfunktion is provided between the housing shells that eccentrically arranged on the hinge axes Attacks joint discs

Hieraus resultiert ein Gelenkarm geschlossenerThis results in a more closed articulated arm

Bauweise, bei dem sich die Herstellung und MontageConstruction in which the manufacture and assembly

ίο des bislang erforderlichen zweiten und mit den Gelenkscheiben gelenkig zu verbindenden Lenkers erübrigtίο the second required so far and with the Articulated disks to be connected to articulated handlebars unnecessary

Zwar ist aus der US-PS 35 66 713 eine Lenkeranordnung bekannt bei der die Paraileiogrammfunktion ein ι > einziger Lenker ausübt aber hierbei sind die Schwingen ortsfest gehaltert so daß dieser Stand der Technik zur Entwicklung des erfindungsgemäßen Gelenkarmes keine ausreichenden technischen Anregungen zu geben vermag.It is true that from US-PS 35 66 713 a handlebar arrangement is known in which the Paraileiogrammfunktion a ι> only handlebar exercises but here the wings are fixed so that this state of the art for Development of the articulated arm according to the invention did not give sufficient technical suggestions able.

Eine unter Umständen bevorzugte Variante des vorbeschriebenen Gegenstandes besteht darin, daß das Schienenpaar von einem inneniiegenden Drahtseil gebildet wird, welches um die Gelenkscheiben herumgeführt wird und an diesen jeweils befestigt ist
Der Stand der Technik und Ausführungsbeispiele der Erfindung sind in den Zeichnungen dargestellt und werden im folgenden näher beschriebei.. Es zeigtA variant of the above-described subject which may be preferred under certain circumstances consists in that the pair of rails is formed by an internal wire rope which is guided around the joint disks and is fastened to them in each case
