Description
Fernbedienung an einem Projektor für Bildwechsel und Fernfokussierung mit flexiblen übertragungselementen Die Erfindung betrifft eine Fernbedienung für Bildwerfer mit Dia-Vorratsbehälter mit flexiblen übertragungselementen.Remote control on a projector for image change and remote focusing with flexible transmission elements The invention relates to a remote control for Projector with slide storage container with flexible transmission elements.
Bekannte Bildwerfer mit Fernbedienungseinrichtung haben den Nachteil, daß sie durch den Einbau von einem großen oder mehreren kleinen Elektromotoren etwa doppelt so teuer sind wie Bildwerfer ohne Fernbedienungseinrichtung gleicher Leistung.Known image projectors with remote control devices have the disadvantage that they can be achieved by installing one large or several small electric motors are twice as expensive as projectors without a remote control device of the same performance.
Es ist auch in der Technik bekannt, die Fernauslösung von Schaltvorgängen mittels Bowdenzug, Drahtauslöser oder flexibler Welle durchzuführen. Die Anwendung von derartigen mechanischen Mitteln, wie Bowdenzug, Drahtauslöser oder flexibler Wellen für die Steuerung von Dia-Wechselvorrichtungen und der Fernfokussierung bei fernsteuerbaren Dia-Projektoren mit Dia-Vorratsbehältern oder Dia-Wechselmagazinen bringt wesentliche Vereinfachungen und preisgünstigere Herstellungskosten mit sich.It is also known in the art to remotely initiate switching operations to be carried out by means of a Bowden cable, cable release or flexible shaft. The application from such mechanical means as Bowden cable, cable release or more flexible Shafts for controlling slide changers and remote focusing remotely controllable slide projectors with slide storage containers or slide change magazines brings significant simplifications and cheaper production costs with it.
Es wäre daher ohne Schwierigkeiten möglich, mittels zweier derartiger mechanischer Mittel, wie Bowdenzüge, Drahtauslöser oder flexibler Wellen, die Fernsteuerung der Schaltungsvorrichtung für den Dia-Vorratsbehälter oder für ein Dia-Wechselmagazin und die Fernsteuerung der Fokussierung zu betätigen.It would therefore be possible without difficulty by means of two such mechanical means, such as Bowden cables, cable releases or flexible shafts, the remote control the switching device for the slide storage container or for a slide change magazine and operate the remote focus control.
Es ist Aufgabe der Erfindung, mehrere Bedienungsvorgänge mit einem solchen übertragungsglied in einfacher Weise zu ermöglichen. Dies wird erfindungsgemäß dadurch erreicht, daß die Fernbedienung an einem Projektor für Bildwechselung und Fernfokussierung über das gleiche flexible übertragungselement erfolgt, wobei ein zur Bedienung angebrachter Knopf so ausgebildet ist, daß der Bildwechsel durch Druck auf den Knopf und die Fokussierung durch Drehung dieses Knopfes an einem Haltegriff betätigt werden kann.It is the object of the invention, several operations with one to enable such a transmission link in a simple manner. This is according to the invention achieved in that the remote control on a projector for picture change and Remote focusing takes place via the same flexible transmission element, with a attached button for operation is designed so that the image change by pressure on the button and the focus by turning this button on a handle can be operated.
Voraussetzung für die Anwendung von mechanisch wirkenden Fernbedienungselementen ist ein leichtgängiges Schaltwerk, das den Bildwechsel und den Magazintransport mit gleichbleibender Kraft durchzuführen gestattet.Requirement for the use of mechanically acting remote control elements is a smooth switching mechanism that changes images and transports the magazine to be carried out with constant force.
Eine mögliche Ausführungsform ist als Schema in der Zeichnung unter Fortfall aller nicht direkt zum Erfindungsgegenstand gehörenden Teile perspektivisch dargestellt.One possible embodiment is shown as a scheme in the drawing below Loss of all parts not directly belonging to the subject matter of the invention in perspective shown.
Durch Druck auf den Betätigungsknopf 1 wird der das eigentliche Schaltwerk betätigende Stößel 2 über die in einem Mantel bekannter Art 3 geführten flexiblen Welle 4 und den im Handgriff 5 geführten Stößel 6 bewegt.By pressing the actuating button 1 , the plunger 2 which actuates the actual switching mechanism is moved over the flexible shaft 4 guided in a jacket of known type 3 and the plunger 6 guided in the handle 5 .
Die im Handgriff 5 eingebaute Druckfeder 7 brinort den Betätigungsknopf 1 mit den übertragungs-C elementen wieder in die Ausgangsstellung zurück, so daß diese Ruhestellungskräfte nicht vom Schaltwerk auszugehen brauchen, wodurch die Reibungskräfte der Welle 4 im Mantel 3 verringert werden.The compression spring 7 built into the handle 5 brings the actuating button 1 with the transmission C elements back into the starting position, so that these rest position forces do not have to come from the switching mechanism, whereby the frictional forces of the shaft 4 in the casing 3 are reduced.
Eine Drehbewegung des Betätigungsknopfes 1 wird über die flexible Welle 4 auf die am Stößel 2 angebrachte Ritzelwelle 8 übertragen. Dabei bewegt sich der am Bildwerfergehäuse parallel geführte Zahnstangenschieber 9 und überträgt diese'Bewegung auf das Projektionsobjektiv 10 zur Scharfeinstellung über den am Zahnstangenschieber 9 befestigten Stift 12, der in der Spiralnut 11 der Objektivfassung dauernd im Eingriff ist. Das Kupplungsstück 13, in welchem die Ritzelwelle 8 geführt ist, wird mittels dem Gewinde 14 oder mittels Bajonett am Bildwerfergehäuse befestigt, so daß das Fernbedienungskabel in einfacher Art mit dem Bildwerfer an- und abkuppelbar ist. Bei der Schubbewegung des Stößels 2 zum Bildtransport kann die Ritzelwelle 8 ungehindert durch die Zähne des Zahnstangenschiebers 9 hindurchgleiten, ohne dabei die Objektivstellung zu beeinflussen.A rotary movement of the actuating button 1 is transmitted via the flexible shaft 4 to the pinion shaft 8 attached to the plunger 2. The rack slide 9 , which is guided in parallel on the projector housing, moves and transmits this movement to the projection lens 10 for focusing via the pin 12 attached to the rack slide 9 , which is permanently engaged in the spiral groove 11 of the lens mount. The coupling piece 13, in which the pinion shaft 8 is guided, is attached to the projector housing by means of the thread 14 or by means of a bayonet, so that the remote control cable can be connected and disconnected to the projector housing in a simple manner. During the pushing movement of the plunger 2 for image transport, the pinion shaft 8 can slide unhindered through the teeth of the rack slide 9 without influencing the lens position.
