Description
Die Erfindung betrifft einen ausbalancierten Tragarm einer Leuchte nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a balanced support arm of a lamp according to the preamble of patent claim 1.
Ein derartiger Tragarm ist aus der DE-GM 73 06 362 bekannt. Dieser vorbekannte ausbalancierte Tragarm weist jedoch den Nachteil auf, daß die als Federanordnung ausgebildeten Kraftübertragungselemente außenseitig an den Armparallelogrammen angeordnet und damit der Gefahr einer Verschmutzung und einer Beschädigung ausgesetzt sind.Such a support arm is known from DE-GM 73 06 362. However, this previously known balanced support arm has the disadvantage that the force transmission elements designed as a spring arrangement are arranged on the outside of the arm parallelograms and are therefore exposed to the risk of contamination and damage.
Aufgabe der Erfindung ist es daher, einen ausbalancierten Tragarm der eingangs genannten Art zu schaffen, der keine außenseitig angeordnete Kraftübertragungselemente aufweist.The object of the invention is therefore to provide a balanced support arm of the type mentioned above, which has no externally arranged force transmission elements.
Erfindungsgemäß wird diese Aufgabe durch die im kennzeichnenden Teil des Patentanspruchs 1 angegebenen Merkmale gelöst. In jedem Armparallelogramm ist eine über einen Gleitkörper erfolgende Federbelastung vorgesehen, wobei jeder Gleitkörper leicht gleitend in einer Hohlstange angeordnet ist. Die Kraftübertragungsteile sind also nicht außen angeordnet, sondern innerhalb der Hohlstangen. Die durch die Erfindung geschaffene Konzeption zeichnet sich durch eine hohe Funktionssicherheit und eine für die Massenherstellung geeignete konstruktive Einfachheit aus. Das Vorsehen von einander entgegengesetzt wirkenden Kräften bei den beiden Armparallelogrammen gewährleistet in günstiger Weise stets stabile ausbalancierte Stellungen des Tragarms, wobei der Tragarm durch die reibungsarmen Gleitkörper leicht in die jeweils gewünschte Stellung gebracht werden kann. Hierdurch wird gleichzeitig in günstiger Weise ein verschleißarmes Arbeiten des Tragarms ermöglicht, wobei die Ausbalancierungswirkung frei von Beeinträchtigung durch äußere Einflüsse bleibt, da die Kraftübertragungselemente im Inneren der Armparallelogramme angeordnet sind.According to the invention, this object is achieved by the features specified in the characterizing part of patent claim 1. In each arm parallelogram, a spring load is provided via a sliding body, with each sliding body being arranged in a hollow rod so that it slides easily. The force transmission parts are therefore not arranged on the outside, but inside the hollow rods. The concept created by the invention is characterized by a high level of functional reliability and a structural simplicity suitable for mass production. The provision of opposing forces in the two arm parallelograms advantageously ensures that the support arm is always in a stable, balanced position, with the support arm being easy to move into the desired position by the low-friction sliding bodies. At the same time, this advantageously enables the support arm to operate with little wear, with the balancing effect remaining free from impairment by external influences, since the force transmission elements are arranged inside the arm parallelograms.
Aus der GB-PS 6 59 561 ist ein Tragarm für eine Leuchte bekannt, bei dem ein Zugelement in einer Hohlstange angeordnet ist. Es ist jedoch lediglich ein Armparallelogramm vorgesehen.GB-PS 6 59 561 discloses a support arm for a lamp in which a tension element is arranged in a hollow rod. However, only one arm parallelogram is provided.
Die US-PS 35 84 793 offenbart einen einarmigen Tragarm, bei dem lediglich eine einzige Druckfeder für die Ausbalancierung vorgesehen ist.US-PS 35 84 793 discloses a single-arm support arm in which only a single compression spring is provided for balancing.
Aus der DE-OS 14 89 340 ist eine Ausgleichsvorrichtung für die Halterung von Lampen bekannt, bei der außerhalb von einem oder mehreren Haltearmen Federn angeordnet sind. Die Federkraft wird auf den oder die Haltearme durch Zwischenelemente übertragen. Auch bei dieser Ausgleichsvorrichtung liegen also die Kraftübertragungsteile außenseitig.DE-OS 14 89 340 discloses a compensation device for holding lamps, in which springs are arranged outside one or more holding arms. The spring force is transmitted to the holding arm(s) through intermediate elements. In this compensation device, too, the force transmission parts are located on the outside.
Zwei Ausführungsbeispiele der Erfindung werden nachstehend anhand der Zeichnung näher erläutert. In dieser zeigtTwo embodiments of the invention are explained in more detail below with reference to the drawing.
Fig. 1 eine Steitenansicht einer Lampe mit einem Tragarm, Fig. 1 is a side view of a lamp with a support arm,
Fig. 2 in Seitenansicht und teilweise im Schnitt das mittlere Gelenk des Tragarmes der Fig. 1 in größerem Maßstab und Fig. 2 in side view and partly in section the middle joint of the support arm of Fig. 1 on a larger scale and
Fig. 3 eine andere Ausführungsform des Verbindungsteils und seiner Lagerung im Gelenkteil in Seitenansicht und in größerem Maßstab. Fig. 3 another embodiment of the connecting part and its bearing in the joint part in side view and on a larger scale.
Wie aus Fig. 1 ersichtlich besteht der Tragarm aus zwei gelenkig miteinander verbundenen Armparallelogrammen 1, 2, 3, 4 bzw. 4, 5, 6, 7, welche die Gelenkteile 1 und 4 und Hohlstangen 2 und 3 bzw. die Gelenkteile 4 und 7 und Hohlstangen 5 und 6 umfassen, wobei die Teile durch Bolzen schwenkbar verbunden sind. Das Gelenkteil 1 trägt einen Lampenschirm 9 und das Gelenkteil 7 umfaßt einen Achszapfen 8 zur schwenkbaren Lagerung des Tragarmes in einem in der Zeichnung nicht dargestelltenTisch- oder Wandhalter.As can be seen from Fig. 1, the support arm consists of two arm parallelograms 1, 2, 3, 4 and 4, 5, 6, 7 which are connected to one another in an articulated manner and which comprise the articulated parts 1 and 4 and hollow rods 2 and 3 or the articulated parts 4 and 7 and hollow rods 5 and 6 , the parts being pivotably connected by bolts. The articulated part 1 carries a lampshade 9 and the articulated part 7 comprises an axle pin 8 for pivotally mounting the support arm in a table or wall holder not shown in the drawing.
In der Hohlstange 3 ist, wie in Fig. 2 dargestellt, eine Zugfeder 10 mit einem Ende befestigt (nicht gezeigt), während das andere Ende in das eine Ende eines Verbindungsteiles 12 in der Form eines Stahldrahtstücks mit hakenförmigen Enden eingehängt ist. Das andere Ende des Verbindungsteils 12 ist am Ende der Hohlstange 2 eingehängt. Es ist einleuchtend, daß die Befestigung dieses Verbindungsteiles in vielen unterschiedlichen Weisen erfolgen kann, vorausgesetzt, daß die Befestigung Zugbeaufschlagung erträgt und die Kraft an den richtigen Angriffspunkten im Gelenkteil überträgt. Zur Herabsetzung der Reibung in der Verbindung zwischen der Zugfeder 10 und dem Verbindungsteil 12 ist ein Gleitkörper 11, beispielsweise aus Nylon, in der Hohlstange 3 vorgesehen.As shown in Fig. 2, a tension spring 10 is fastened at one end (not shown) in the hollow rod 3 , while the other end is hooked into one end of a connecting part 12 in the form of a piece of steel wire with hooked ends. The other end of the connecting part 12 is hooked onto the end of the hollow rod 2. It is obvious that the fastening of this connecting part can be carried out in many different ways, provided that the fastening can withstand tensile loading and transmits the force to the correct points of application in the joint part. To reduce the friction in the connection between the tension spring 10 and the connecting part 12 , a sliding body 11 , for example made of nylon, is provided in the hollow rod 3 .
Die Ausbalancierung des anderen Armparallelogramms 4, 5, 6, 7 erfolgt mittels einer Druckfeder 13, deren eines Ende gegen eine in der Zeichnung nicht dargestellte Auflage anliegt, während das andere Ende einen Gleitkörper 15, beispielsweise aus Nylon, an einem Zapfen 16 trägt und am anderen Ende eine hohle Lagerfläche 17 zur Auflage des einen Endes des Verbindungsteils 14 aufweist. Das andere Ende des Verbindungsteils 14 hat die Form einer zweizinkigen Gabel 19, die auf einem Lagerzapfen 18 im Gelenkteil 4 gelagert ist.The balancing of the other arm parallelogram 4, 5, 6, 7 is carried out by means of a compression spring 13 , one end of which rests against a support not shown in the drawing, while the other end carries a sliding body 15 , for example made of nylon, on a pin 16 and has a hollow bearing surface 17 at the other end for supporting one end of the connecting part 14. The other end of the connecting part 14 has the shape of a two-pronged fork 19 which is mounted on a bearing pin 18 in the joint part 4 .
Zur Erhöhung des Ausbalancierungsmomentes kann, wie in Fig. 3 dargestellt, die zweizinkige Gabel 19 am Ende des Verbindungsteils 14 breit genug für eine Auflage gegen zwei nebeneinander liegende Lagerzapfen 18 oder gegen einen breiten Lagerzapfen wie mit gestrichelten Linien in Fig. 3 angedeutet gestaltet sein. Auf diese Weise wird der Angriffspunkt der Feder von der einen zur anderen Gabelzinke verschoben.To increase the balancing moment, as shown in Fig. 3, the two-pronged fork 19 at the end of the connecting part 14 can be designed to be wide enough to rest against two adjacent bearing pins 18 or against a wide bearing pin as indicated by dashed lines in Fig. 3. In this way, the point of application of the spring is shifted from one fork prong to the other.
