Bei den bis jetzt bekannten Projektionsbogenlampen mit winklig zueinander angeordneten Kohlen erfolgt die Verstellung der Kohlen von der Spindel aus meist durch starre Organe, ζ. Β. Hebel oder Zahnräder. Die Anwendung dieser Elemente hat jedoch nicht immer zur Vereinfachung der Konstruktion der Lampe geführt, zumal bei Lampen mit recht- oder stumpfwinklig zu-In the previously known projection arc lamps with angled to one another Coals, the coals are usually adjusted from the spindle by rigid organs, ζ. Β. Levers or gears. However, the application of these elements does not always simplify the design the lamp, especially since lamps with right or obtuse angles
einander angeordneten Kohlen. Man hat deshalb diese Schwierigkeit durch Verwendung biegsamer Organe, z. B. Drahtseile oder Ketten zu verbessern versucht, um mittels dieser die Bewegung von der horizontalenarranged coals. One therefore has this difficulty through use flexible organs, e.g. B. tries to improve wire ropes or chains by means of this the movement from the horizontal
»5 Ebene in die vertikale in einfacherer Weise überzuleiten. Diese Mittel haben jedoch nur in beschränktem Maße die Nachteile dter starren Übertragung beseitigt. Die Erfindung beseitigt diese Nachteile vollkommener»To transfer 5 level into the vertical in a simpler way. However, these funds only have to a limited extent eliminates the disadvantages of rigid transmission. The invention eliminates these disadvantages more completely
ao dadurch, daß die Bewegungsübertragung von der horizontalen Ebene in die vertikale durch ein biegsames Stahlband stattfindet, welches wechselweise auf Druck und Zug beansprucht wird.ao in that the transfer of motion from the horizontal plane to the vertical by a flexible steel band takes place, which alternately stresses pressure and tension will.
In der Zeichnung ist die Erfindung in einer »5 Ausführungsform bei einer Lampe dargestellt, deren Kohlen rechtwinklig zueinander angeordnet sind und von einer Spindel aus gemeinschaftlich verstellt werden. Die obere Kohle "erhält ihre horizontale Bewegung durch die Spindel α, deren Bewegung gleichzeitig durch ein Stahlband b, welches in einer Führung c geleitet werden kann, auf die untere, vertikal verschiebbare Kohle übertragen wird.In the drawing, the invention is shown in an embodiment of a lamp, the coals of which are arranged at right angles to one another and are jointly adjusted by a spindle. The upper coal "receives its horizontal movement through the spindle α, the movement of which is simultaneously transmitted to the lower, vertically displaceable coal through a steel belt b, which can be guided in a guide c.
