Die Größe der axialen Vorspannung des Achsbolzens 12 ist so gewählt, daß einerseits eine ausreichende Friktionsmitnahmehaftung der Isolierscheibe 8 mit den beiderseits angrenzenden Drehscheiben 9, 9ʹ und andererseits eine freie Drehbarkeit der derart mit der Isolierscheibe eine Einheit bildenden beiden Drehscheiben in bezug zu den beiderseitig angeordneten feststehenden Lagerkörpern 13 bei Gewährleistung eines elektrischen Kontaktes zwischen diesen ermöglicht wird.
Auch wird nach dem Drehen der Leuchte 1 bzw. nach erfolger Einstellung ein Festhalten derselben in geeigneter Stellung durch Friktionsspannung ermöglicht.

Die beiden Stäbe 17 sind mit den von der Leuchte 1 abgekehrten Enden derselben in Bohrlöchern 19 eines Haltekörpers 20 mit Friktionshaftung frei drehbar und frei axial verschiebbar gelagert. Als Haltekörper 20 wird vorzugsweise ein Verbindungselement verwendet, in welchem Bohrlöcher 19 angeordnet werden, derart, daß die Stäbe 17 in diesem mit Friktionshaftung gehalten werden. Wird eine Verkleinerung des Abstandes der Leuchte von der vom Verbindungselement 20 gehaltenen Platte 21 gewünscht, so ist es lediglich erforderlich, die Leuchte zusammen mit den mit Friktionshaftung in den Bohrlöchern 19 lagernden Stäben durch die Bohrlöcher 19 der Verbindungselemente nach unten zu verschieben.The two
Die beiden Stäbe 17, 17ʹ sind in einem bestimmten gegenseitigen Abstand angeordnet, so daß bei einer Torsionsdrehung derselben zusammen mit dem Drehgelenk 7 und mit der Leuchte 1 um die Längsmittelachse 22 ein Schwenken der Leuchte 1 um 340° ermöglicht wird, ohne daß die beiden spannungsführenden Stäbe 17, 17ʹ einander zu berühren vermögen. Eine derartige Torsionsdrehung erfolgt vergleichsweise ähnlich, wie es bei der menschlichen Hand beim Drehen derselben um Elle und Speiche der Fall ist.The two
Als Haltekörper 20 kann ein Verbindungselement verwendet werden,sofern es aus elektrisch nicht leitendem Material. wie aus Kunststoff, besteht. Derartige Verbindungselemente 20 können an jeder beliebigen Stelle der Platten 21 befestigt werden.A connecting element can be used as the holding
Mit der erfindungsgemäßen Vorrichtung ist es auf einfache Weise möglich, eine äußerst helle Ausleuchtung mit sparsamem Stromverbrauch an jeder gewünschten Stelle einer Platte zu erzielen, wobei die fast universelle Verstellbarkeit des von der Scheinwerferspiegelkappe der Leuchte erzeugten Lichtkegels mit unkomplizierten einfachen Mitteln erreichbar ist.With the device according to the invention it is possible in a simple manner to achieve extremely bright illumination with economical power consumption at any desired location on a plate, the almost universal adjustability of the light cone produced by the headlight mirror cap of the lamp being achievable with uncomplicated, simple means.
Es sei noch darauf hingewiesen, daß eine derartige Niedervolt-Halogenleuchte äußerst sparsam ist, da eine solche mit 50 Watt Stromverbrauch eine Lichtwirkung von vergleichsweise 150 Watt bei anderen Lampen bedingt, wobei die Wärmeerzeugung bei weitem geringer ist als bei üblichen Glühlampen.It should also be pointed out that such a low-voltage halogen lamp is extremely economical, since such a lamp with a power consumption of 50 watts results in a lighting effect of comparatively 150 watts for other lamps, the heat generation being far less than with conventional incandescent lamps.
Die Stäbe 17 werden üblicherweise mit einer Länge von etwa 60 cm hergestellt, wodurch bei entsprechender Richtungsverstellung eine beliebige Ausleuchtung der jeweils erwünschten Fläche erzielbar ist, was insbesondere dadurch ermöglicht wird, daß die Leuchte 1 um zwei voneinander unabhängige und zueinander lotrecht verlaufende Achsen geschwenkt werden kann und zwar durch Drehen um die Drehungsachse 11 des Drehgelenkes 7 und durch Torsionsdrehung der Stäbe 17, 17ʹ um die Längsmittelachse 22, wobei bei maximaler Ausladung der Stäbe der Schwenkungsbereich max. 340° beträgt.The
Soll der die Leuchte 1 tragende Haltekörper an einer beliebigen Platte befestigt werden, so wird er in Form einer Schraubzwinge 30 gestaltet (s. Fig. 7, 8 und 9), die aus zwei, jeweils von einer angeformten Gleithülse 32, 32ʹ kragträgerförmig ausladenden Klemmbackenhälfte 31, 31ʹ aus elektrisch nicht leitendem Material besteht.If the holding body carrying the
Die Gleithülse 32, 32ʹ ist mit zwei Bohrlöchern 19, 19ʹ versehen (s. Fig. 9), durch die sich zwei, die Leuchte 1 tragende elektrisch leitende, voneinander elektrisch isolierte Stäbe 17, 17ʹ mit Friktionshaftung hindurch erstrecken, derart, daß die Leuchte 1 von Hand in beliebigem Abstand von der Schraubzwinge 30 entfernt eingestellt werden kann.The sliding
In der Gleithülse 32, 32ʹ jeder der Klemmbackenhälften 31, 31ʹ der verstellbaren Schraubzwinge 30 ist ein parallel zu den Bohrlöchern 19, 19ʹ mittig verlaufendes drittes Bohrloch 34 (Fig. 10) zur Aufnahme einer sich durch die Gleithülsen 32, 32ʹ frei hindurch erstreckenden Gewindespindel 35 vorgesehen, deren freies Ende in eine in der Gleithülse 32ʹ der unteren Klemmbackenhälfte 31 nicht drehbar gelagerten Mutter 36 eingreift (Fig. 9), und deren oberes Ende in eine sich auf die obere Gleithülse 32 stützende, von Hand frei drehbare Rändelmutter 43 gewindegängig eingreift.In the sliding
Damit die Schraubzwinge an einer Platte 38 beliebiger Dicke befestigt werden kann, weisen die beiden Klemmbackenhälften 31, 31ʹ sowohl an ihren, der Gleithülse 32, 32ʹ zugekehrten Enden angeordnete, als auch an ihrem freien Ende befindliche, und in einer lotrecht zu den Stäben 17, 17ʺ verlaufenden Ebene miteinander fluchtende Stützflächen 39, 39ʹ bzw. 40, 40ʹ auf.So that the screw clamp can be fastened to a
Soll die Schraubzwinge an einem Rohr 37 befestigt werden (s. Fig. 10 und Fig. 11), so sind die die Lager pfannen 33, 33ʹ bildenden Innenflächen der Schraubzwinge mit einem dem Rohrdurchmesser entsprechenden Radius bogenförmig gestaltet, damit sie die Rohre beiderseits formschlüssig umfassen können. Zur Befestigung der Schraubzwinge 30 an einem Rohr 37 wird dieses in die Lagerpfanne 33, 33ʹ eingebracht. Dann wird die Rändelmutter 43 von Hand festgeschraubt, bis die Klemmbackenhälften 31, 31ʹ das Rohr 37 formschlüssig umfassen.If the screw clamp is to be fastened to a pipe 37 (see FIGS. 10 and 11), the inner pans 33, 33ʹ forming the bearing pans are designed with an arc in a radius corresponding to the pipe diameter, so that they embrace the pipes on both sides in a form-fitting manner can. To attach the
Um die Schraubzwinge auch in einem Rohr mit unterschiedlichem Durchmesser befestigen zu können, ist die Lagerpfanne 33, 33ʹ mit verschiedem großen Radius ausgebildet, und zwar weist der mittlere Bereich derselben einen kleineren Radius R₁ auf, als die mit einem größeren Radius R₂ gestalteten seitlichen Bereiche.In order to be able to fix the screw clamp in a pipe with different diameters, the bearing pan is 33, 33ʹ formed with different large radius, namely the central region of the same has a smaller radius R₁ than the side regions designed with a larger radius R₂.
Auf diese Weise kann die Schraubzwinge mit dem mittleren Bereich ihrer Lagerpfanne ein Rohr mit kleinerem Durchmesser formschlüssig umfassen, und mit ihren seitlichen Bereichen ein Rohr größeren Durchmessers formschlüssig halten.In this way, the screw clamp with the central region of its bearing socket can encompass a pipe with a smaller diameter, and with its lateral regions can hold a pipe with a larger diameter in a form-fitting manner.
Es ist somit möglich, mit ein und derselben Klemmbackenhälfte 31, 31ʹ die Schraubzwinge 30 wahlweise an einem Rohr oder an einer Platte befestigen zu können.It is thus possible, with one and the
