Farbf ilterhalterColor filter holder
Die Erfindung betrifft einen Farbfilterhalter, der in Scheinwerfer für Bühnen- und Studiozwecke einschiebbar oder einlenkbar ist und welcher aus zwei aneinander angelenkten Rahmen besteht, zwischen die die Filterscheibe einlegbar ist.The invention relates to a color filter holder which can be inserted or guided into spotlights for stage and studio purposes and which consists of two frames hinged to one another, between which the filter disk can be inserted.
Solche Scheinwerfer werden in großem Umfang, beispielsweise bei musikalischen Großveranstaltungen eingesetzt. Beleuchtungseinrichtungen mit mehreren hundert derartigen Scheinwerfern sind die Regel. Daher müssen die Scheinwerfer und ihre Bedienungselemente einfach und billig herstellbar sein.Such spotlights are used on a large scale, for example at large musical events. Lighting systems with several hundred such spotlights are the norm. Therefore, the spotlights and their operating elements must be simple and inexpensive to manufacture.
So bestehen z. B. die üblichen Farbfilterhalter aus zwei Metallrahmen, die ähnlich einem Faltblatt aneinander angelenkt ist. Die Filterscheibe, die zumeist aus einer eingefärbten Kunststoffolie besteht, wird einfach zwischen die beiden Rahmen eingelegt. Danach wird der FilterhalterFor example, the usual color filter holders consist of two metal frames that are hinged together like a leaflet. The filter disc, which is usually made of a colored plastic film, is simply placed between the two frames. The filter holder is then
in die Frontpartie des Scheinwerfers eingeschoben.inserted into the front section of the headlight.
Da im Betrieb solcher Scheinwerfer der Wechsel der Filter sehr schnell erfolgen muß, werden die benötigten Kunststoffolien einfach von entsprechenden Kunststoffrollen abgetrennt und zwischen die Rahmen des Farbfilterhalters gelegt. Damit erfolgt aber keine exakte Befestigung der Filterscheibe, so daß diese leicht verrutschen kann.Since the filters have to be changed very quickly when using such headlights, the required plastic films are simply cut from the corresponding plastic rolls and placed between the frames of the color filter holder. However, this does not ensure that the filter disc is attached precisely, so it can easily slip.
Der Erfindung liegt die Aufgabe zugrunde, diese Nachteile zu beseitigen, wozu ein ebenfalls zweiteiliger Filterhalter der beiden Filterrahmen angegeben wird, wobei der Rahmen mit Verbindungsmitteln versehen ist, welche dem gegenseitigen Festklemmen der beiden Rahmen und damit dem Spannen der zwischen den beiden Rahmen eingelegten Filterscheibe dienen.The invention is based on the object of eliminating these disadvantages, for which purpose a two-part filter holder of the two filter frames is provided, wherein the frame is provided with connecting means which serve to clamp the two frames together and thus to tension the filter disk inserted between the two frames.
In bevorzugter Ausführungsform der Erfindung sind die Verbindungsmittel von mindestens einer, vorzugsweise vier Aussparungen sowie von Rastklammern gebildet, die in die Aussparungen einsetzbar sind.In a preferred embodiment of the invention, the connecting means are formed by at least one, preferably four recesses and by locking clips that can be inserted into the recesses.
Die Rasterklemmen bedingen also einerseits eine Befestigung der Filterscheiben in der Weise, daß sie nicht verrutschen können, andererseits bewirken sie ein Spannen der eingelegten Farbfolie, ohne daß zusätzliche Befestigungsmanipulationen erforderlich sind. Es besteht jedoch auch die Möglichkeit, die Verbindungsmittel als 0 Klettverschlußelement zu gestalten.On the one hand, the grid clamps ensure that the filter discs are secured in such a way that they cannot slip, and on the other hand, they ensure that the inserted color film is tensioned without any additional fastening manipulations being necessary. However, it is also possible to design the connecting means as a Velcro fastener.
Bei der Ausführung der Erfindung empfiehlt es sich, die beiden Rahmen durch ein derart ausgebildetes Gelenk zu verbinden, daß ein Aufklappen der beiden Rahmen in eine gemeinsame Ebene möglich ist. Dadurch wird das Einlegen und das Festklemmen des von einer rollenförmigen Farbfolie abgetrennten Filters erheblich erleichtert.When implementing the invention, it is recommended to connect the two frames with a joint designed in such a way that it is possible to open the two frames into a common plane. This makes it considerably easier to insert and clamp the filter that has been separated from a roll of color film.
Die beiden Rahmen werden zweckmäßig aus wärmebeständigem Kunststoff gespritzt und sind daher auf diese Weise als Massenartikel kostengünstig herstellbar.The two frames are conveniently injection-molded from heat-resistant plastic and can therefore be manufactured cost-effectively as mass-produced items.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt. Es zeigen:An embodiment of the invention is shown in the drawing.
Fig. 1 die Aufsicht auf einen zusammengeklappten und mit Scharnier versehenen Doppelrahmen,Fig. 1 is a top view of a folded and hinged double frame,
Fig. 2 die Ausbildung einer Rastklammer, Fig. 3 eine andere Ausführungsform einer Rastklammer.Fig. 2 shows the design of a locking clip, Fig. 3 shows another embodiment of a locking clip.
In Fig. 1 der Zeichnung sind die beiden aufeinander liegenden Rahmen, welche mit einem Scharnier 6 verbunden sind, mit 1 und 2 bezeichnet. Diese Rahmen haben eine innere Aussparung mit dem Innendurchmesser 4. Innerhalb dieses Durchmessers 4 verläuft der aktive Teil der Filterscheibe.In Fig. 1 of the drawing, the two frames lying on top of each other, which are connected with a hinge 6, are designated 1 and 2. These frames have an inner recess with an inner diameter of 4. The active part of the filter disk runs within this diameter 4.
Die Rahmen sind mit vier Aussparungen 3 versehen, welche 0 dem Einsetzen von Rastklammern 7 und 8 dienen, für die in den Fig. 2 und 3 zwei Ausführungsformen dargestellt sind. Diese Aussparungen 3 verlaufen auf einem Teilkreis 5.The frames are provided with four recesses 3, which serve to insert locking clips 7 and 8, two embodiments of which are shown in Figs. 2 and 3. These recesses 3 run on a partial circle 5.
Die Ausbildung der Rastklammern gemäß Fig. 2 und 3, welche beispielsweise auf dem unteren Rahmen 2 befestigt sind, ermöglicht nach dem erfolgten Einlegen der Farbfolie und dem Zuklappen der beiden Rahmen ein Spannen der Folie, so daß eine Verschiebung nicht erfolgen kann. Nach dem Einlegen der in der Zeichnung nicht dargestellten Farbfolie wird der Doppelrahmen 1, 2 gemäß Fig. 1 in den Scheinwerfer eingeschoben.The design of the locking clips according to Fig. 2 and 3, which are attached to the lower frame 2, for example, allows the film to be tensioned after the color film has been inserted and the two frames have been closed, so that it cannot shift. After inserting the color film (not shown in the drawing), the double frame 1, 2 is pushed into the headlight according to Fig. 1.
