Abstract
Description
Leuchten, deren Leuchtenschirm beispielsweise in einer horizontalen Ebene verschiebbar ist, weisen ein derartiges schwenkbares Leuchtenelement auf. Hierbei handelt es sich beispielsweise um zwei über ein Gelenk miteinander verbundene Leuchtenarme, die gelenkig miteinander verbunden sind. An einem Ende eines der beiden Leuchtenarme ist der Leuchtenschirm und an einem Ende des anderen Leuchtenarms ist ein Leuchtenhalter, wie ein Leuchtenfuß oder eine Deckenbefestigung, vorgesehen. Die gelenkige Verbindung der beiden Leuchtenarme ist derart ausgebildet, dass der eine gegenüber dem anderen Leuchtenarm in einer horizontalen Ebene verschwenkt werden kann. Eine Kippbewegung des Leuchtenschirms, d.h. ein Schwenken des Leuchtenschirms um eine horizontale Achse, ist nicht möglich. Beim Verschwenken des Leuchtenarms in einer horizontalen Ebene treten insbesondere bei mit dem Leuchtenarmende verbundenen schweren Leuchtenschirmen hohe Biegekräfte in dem Lager auf. Dies führt dazu, dass insbesondere bei ausgeschwenktem Leuchtenarm und bei schweren Leuchtenschirmen, beispielsweise über 2 kg, der Leuchtenarm nicht mehr horizontal ausgerichtet ist.Luminaires whose lampshade, for example is displaceable in a horizontal plane, have such swiveling light element. This is for example at two over a jointed lamp arms that are articulated with each other are connected. At one end is one of the two lamp arms the lampshade and is at one end of the other lamp arm a lamp holder, such as a lamp base or a ceiling mount, intended. The articulated connection of the two lamp arms is formed in such a way that one opposite the other lamp arm can be pivoted in a horizontal plane. A tilting movement of the lampshade, i.e. a pivoting of the lampshade by one horizontal axis is not possible. When swiveling the lamp arm, step in a horizontal plane especially with heavy lampshades connected to the end of the lamp arm high bending forces in the camp. this leads to that especially when the lamp arm is swung out and heavy lampshades, for example over 2 kg, the lamp arm is not is more horizontally aligned.
Aufgabe der Erfindung ist es, ein schwenkbares Leuchtenelement zu schaffen, bei welchem auch bei schweren Leuchtenschirmen und bei ausgelenktem Leuchtenarm der Leuchtenarm im Wesentlichen horizontal angeordnet bleibt.The object of the invention is a to create swiveling lamp element, in which even with heavy Lampshades and the lamp arm when the lamp arm is deflected remains essentially horizontal.
Die Lösung der Aufgabe erfolgt erfindungsgemäß durch die Merkmale des Anspruchs 1.According to the invention, the object is achieved by the features of claim 1.
Das erfindungsgemäße schwenkbare Leuchtenelement weist einen in einer Horizontalebene verschwenkbaren Leuchtenarm auf, der mit einem ersten Lageraufnahmeelement verbunden ist. Ferner ist ein zweites Lageraufnahmeelement vorgesehen, das beispielsweise mit einem zweiten Leuchtenarm, einem Leuchtenfuß oder einer Deckenbefestigung verbunden sein kann. Zwischen den beiden Lageraufnahmeelementen ist erfindungsgemäß ein Axiallager und ein Radialkräfte aufnehmendes Rollenlager angeordnet. Bei dem Rollenlager handelt es sich beispielsweise um ein Pendelrollenlager, ein Rollenlager mit kegelförmigen Rollen und vorzugsweise ein Rollenlager mit kreiszylindrischen Rollen. Besonders bevorzugt ist das Vorsehen eines Nadellagers, da dies einen geringen Bauraum aufweist. Bei dem Axiallager handelt es sich um ein Lager, das ggf. zusätzlich zu den Axialkräften auch Radialkräfte aufnehmen kann. Bevorzugt ist die Verwendung eines Kugellagers. Es kann sich jedoch auch um ein reines Axiallager, ein Schrägkugellager etc. handeln.The pivotable lamp element according to the invention has a lamp arm pivotable in a horizontal plane on, which is connected to a first bearing receiving element. Furthermore is a second bearing receiving element is provided, for example connected to a second lamp arm, a lamp base or a ceiling mount can be. According to the invention, there is an axial bearing between the two bearing receiving elements and a radial forces receiving roller bearing arranged. The roller bearing is acting it is, for example, a spherical roller bearing, a roller bearing with conical Rollers and preferably a roller bearing with cylindrical rollers. The provision of a needle bearing is particularly preferred since this has a small installation space. The thrust bearing is to a warehouse that may be additional to the axial forces also radial forces can record. The use of a ball bearing is preferred. However, it can also be a pure thrust bearing, an angular contact ball bearing etc. act.
Vorzugsweise ist das Rollenlager im Wesentlichen vertikal angeordnet. Beim Vorsehen eines insbesondere als Nadellager ausgebildeten Rollenlagers ist deren Längsachse vorzugsweise vertikal angeordnet. Es handelt sich somit ausschließlich um ein Radialkräfte aufnehmendes Rollenlager. Auf Grund des Vorsehens eines derartigen Rollenlagers können die bei ausgeschwenktem Leuchtenarm im Lagerbereich auftretenden Biegemomente und Kräfte gut aufgenommen werden. Ein Auslenken oder Herauskippen des Leuchtenarms aus seiner Horizontalebene ist auf Grund der erfindungsgemäß vorgesehenen zwei Lager, bei denen es sich um ein Axiallager und ein Radialkräfte aufnehmendes Rollenlager handelt, vermieden oder zumindest stark verringert.The roller bearing is preferably arranged essentially vertically. When providing one in particular roller bearing designed as a needle bearing is its longitudinal axis preferably arranged vertically. It is therefore only a radial forces receiving roller bearing. Because of the provision of such Roller bearing can those occurring in the storage area when the lamp arm is swung out Bending moments and forces be well received. A deflection or tilting of the lamp arm from its horizontal plane is due to that provided by the invention two bearings, which are a thrust bearing and a radial force Roller bearings act, avoided or at least greatly reduced.
Vorzugsweise weist eines der Leuchtenaufnahmeelemente einen vorzugsweise zylindrischen vertikal verlaufenden Ansatz auf. Der vertikale Ansatz ist erfindungsgemäß von dem Rollenlager umgeben. Das andere Lageraufnahmeelement weist vorzugsweise einen hülsenförmigen Ansatz auf, der das Rollenlager umgibt. Der vertikal verlaufende Ansatz wird somit erfindungsgemäß zusammen mit dem Rollenlager in den hülsenförmigen Ansatz eingesteckt.Preferably, one of the lamp receptacle elements a preferably cylindrical vertical approach. According to the invention, the vertical approach is surrounded by the roller bearing. The other bearing receiving element preferably has a sleeve-shaped extension that surrounds the roller bearing. The vertical approach is thus together according to the invention with the roller bearing in the sleeve-shaped approach plugged in.
Das Axiallager ist vorzugsweise ebenfalls zwischen dem zylindrischen vertikalen Ansatz und dem hülsenförmigen Ansatz angeordnet.The thrust bearing is preferably also between the cylindrical vertical approach and the sleeve-shaped approach.
Bei einer besonders bevorzugten Ausführungsform erfolgt das Verbinden der beiden Lageraufnahmeelemente durch das Axiallager. Das Axiallager ist somit derart angeordnet, dass es in montiertem Zustand ein Auseinanderziehen der beiden Lageraufnahmeelemente, d.h. insbesondere ein Herausziehen des zylindrischen vertikal verlaufenden Ansatzes aus dem hülsenförmigen Ansatz, verhindert.In a particularly preferred embodiment the two bearing support elements are connected by the Thrust bearing. The axial bearing is thus arranged such that it in the assembled state, pulling apart the two bearing receiving elements, i.e. in particular pulling out the cylindrical vertically extending extension from the sleeve-shaped approach, prevented.
Nachfolgend wird die Erfindung anhand einer bevorzugten Ausführungsform unter Bezugnahme auf die anliegende Zeichnung näher erläutert.The invention is explained below a preferred embodiment explained in more detail with reference to the accompanying drawing.
