Description

Feder-Gewichtsausgleichsvorrichtung für eine an einem Schwenkarm angreifende Last, z. B. für eine Operationsdeckenleuchte Die Erfindung betrifft eine Gewichtsausgleichsvorrichtung, bei welcher eine Last, z. B. eine Operationsdeckenleuchte, an einem Schwenkarm hängt, an dem außerhalb seiner Schwenkachse eine Ausgleichsfeder angreift, die innerhalb eines Tragrohres für den Schwenkarm angeordnet ist, an dessen Ende sich die für den Angriff der Ausgleichsfeder erforderlichen Bauelemente innerhalb eines am unteren Ende des Tragrohres gebildeten Gelenkkopfes befinden.Spring counterbalance device for one that acts on a swivel arm Load, e.g. B. for a surgical ceiling light The invention relates to a weight compensation device, at which a load, e.g. B. a surgical ceiling light, hangs on a swivel arm, on the outside of its pivot axis a compensating spring engages the inside a support tube for the swivel arm is arranged, at the end of which the for the attack of the balancing spring required components within one at the bottom End of the support tube formed joint head are located.

Bei einer derartigen Vorrichtung ist es nachteilig, claß das Gelenk nur ungenügend abgeschirmt ist, indem beispielsweise im Gelenkkopf eine dem maximalen Verstellwinkel des Schwenkarmes entsprechende Öffnung vorgesehen ist. Dadurch kann einerseits Schmieröl nach außen gelangen und andererseits kann das Gelenk durch Staub verschmutzt werden.In such a device it is disadvantageous that the joint is only inadequately shielded, for example by one of the maximum in the joint head Adjustment angle of the swivel arm corresponding opening is provided. This can on the one hand lubricating oil get to the outside and on the other hand the joint can through Dust become dirty.

Erfindungsgemäß werden diese Nachteile dadurch vermieden, daß der Gelenkkopf his auf die Bohrung für die vorzugsweise beiderseits durch ihn nach außen geführte, starr mit einem insbesondere gabelförrnig ausgebildeten Ende des Schwenkarmes verbundene Schwenkachse völlig geschlossen ist.According to the invention these disadvantages are avoided in that the Articulated head except for the hole for which preferably both sides through it to the outside guided, rigid with an in particular fork-shaped end of the swivel arm connected pivot axis is completely closed.

An Hand eines Ausführungsbeispiels soll der Gegenstand der Erfindung nachfolgend erläutert werden.The subject matter of the invention is to be based on an exemplary embodiment are explained below.

In der Fig. 1. ist eine Operationsdeckenleuchte mit ihrer Aufhängevorrichtung dargestellt. Das Lampengehäuse 1 ist in einer im Schwenkarm 2 drehbar gelagerten Gabel 3 drehbar aufgehängt. Der Schwenkarm 2 wiederum ist mit einer Gabel 4 an einem an der Decke befestigten Tragrohr 5 gelagert. Wenn die Drehachse .A für das Lampengehäuse 1 und die Drehachse B für die Gabel 3 durch den Schwerpunkt des Lampengehäuses 1 und die Achse B außerdem durch den Schwerpunkt der Gabel 3 geführt ist, so ist das auf den Schwenkarm 2 bei einer bestimmten Stellung einwirkende :Moment von der Einstellung des Lampengehäuses unabhängig.In Fig. 1 is a surgical ceiling light with its suspension device shown. The lamp housing 1 is rotatably mounted in a pivot arm 2 Fork 3 rotatably suspended. The pivot arm 2 is in turn with a fork 4 on one mounted on the ceiling support tube 5. If the axis of rotation .A for the lamp housing 1 and the axis of rotation B for the fork 3 through the center of gravity of the lamp housing 1 and the axis B is also guided through the center of gravity of the fork 3, so that is acting on the swivel arm 2 in a certain position: moment of the setting of the lamp housing independently.

In der Fig. 2 sind die für die Erfindung wesentlichen Teile veranschaulicht. Im Inneren des Tragrohres 5 ist die Ausgleichsfeder 6 untergebracht und im oberen Teil des Tragrohres 5 befestigt. Das untere Ende des Tragrohres 5 ist durch einen Gelenkkopf 7 abgeschlossen, in dem eine Achse 8 gelagert ist, deren beide nach außen geführte Enden mit der Gabel 4 des Schwenkarmes 2 starr verbunden sind. Innerhalb des Gelenkkopfes 7 weist die Achse 8 einen hebelartigen Ansatz 9 auf, an dessen Ende ein Seil 10 befestigt ist, das über eine im Gelenkkopf 7 angebrachte Umlenkrolle 11 mit dem in der Fig. 2 unteren Ende der Feder 6 verbunden ist.In Fig. 2, the essential parts for the invention are illustrated. The compensating spring 6 is housed in the interior of the support tube 5 and in the upper one Part of the support tube 5 attached. The lower end of the support tube 5 is through a Joint head 7 completed, in which an axis 8 is mounted, both of which are outwardly guided ends with the fork 4 of the pivot arm 2 are rigidly connected. Within of the joint head 7, the axis 8 has a lever-like extension 9 on which At the end of a rope 10 is attached, which is attached to a pulley in the joint head 7 11 is connected to the lower end of the spring 6 in FIG. 2.
