Description

Bildwerfer mit einem Schutzgehäuse Die Erfindung geht aus von einem Bildwerfer mit einem die Bedienungs- und optischen Teile umschließenden Schutzgehäuse, das auch beim Betrieb des Bildwerfers mit diesem verbunden bleibt.Projector with a protective housing The invention is based on one Projector with a protective housing enclosing the operating and optical parts, which remains connected to the projector even when it is in operation.

Das Neue besteht darin, daß bei einem solchen Bildwerfer gemäß der Erfindung das Schutzgehäuse zum Übergang auf den Betriebszustand in seiner Lage lediglich derart veränderbar ist, daß zwar alle Bedienungsteile freigelegt «-erden, jedoch das Lampengehäuse so umschlossen bleibt, daß es durch das Schutzgehäuse gegen Berührung geschützt ist. Auf diese Weise ist auf einfache Art ein Berührungsschutz für das Lampengehäuse gebildet, wie er besonders bei kleinen Bildwerfern wichtig ist, da hier das Lampenhaus meist sehr klein ist und sich infolgedessen sehr erwärmt.The novelty is that with such a projector according to the Invention, the protective housing for the transition to the operating state in its position can only be changed in such a way that, although all operating parts are exposed, however, the lamp housing remains enclosed so that it is protected against by the protective housing Touch is protected. This is a simple way of protecting against accidental contact Formed for the lamp housing, as it is particularly important for small projectors is because here the lamp house is usually very small and as a result heats up a lot.

Als Ausführungsbeispiel des Erfindungsgegenstandes ist ein Bildwerfer im Betriebszustand zeichnerisch dargestellt, und zwar in Abb. z von der Seite und in Abb. z von oben gesehen.An image projector is an exemplary embodiment of the subject matter of the invention shown in the drawing in the operating state, namely in Fig. z from the side and seen from above in fig.

Das Schutzgehäuse ist von zwei Gehäuseteilen A, B gebildet, welche durch die Spreizen Sp miteinander und beweglich mit dem Gerät verbunden sind. Nach Hochklappen des Objektivs lassen sich die Gehäuseteile A, B so bewegen, daß das gesamte Gerät umschlossen ist. Im Betriebszustand legen, wie dargestellt, die zurückgeschobenen Gehäuseteile die Bedienungsorgane frei und schützen jedoch das Lampengehäuse L gegen Berührung.The protective housing is formed by two housing parts A, B , which are connected to one another and movably to the device by the spreaders Sp. After folding up the lens, the housing parts A, B can be moved so that the entire device is enclosed. In the operating state, as shown, the retracted housing parts expose the operating elements and protect the lamp housing L against contact.

PATENTANSPRUCH: Bildwerfer mit einem die Bedienungs-und optischen Teile umschließenden Schutzgehäuse, das auch beim Betrieb des Bildwerfers mit diesem verbunden bleibt, dadurch gekennzeichnet, daß das Schutzgehäuse zum Übergang auf den Betriebszustand in seiner Lage lediglich derart veränderbar ist, daß zwar alle Bedienungsteile freigelegt werden, jedoch das Lampengehäuse so umschlossen bleibt, daß es durch das Schutzgehäuse gegen Berührung geschützt ist. Zur Abgrenzung des Anmeldungsgegenstandes vom Stand der Technik sind im Erteilungsverfahren folgende Druckschriften in Betracht gezogen worden: nzösische Patentschrift ... Nr. 408 7q.0; ;fr; Proj. H. 7383a« der Firma E. Seitz, Wetzlar, betitelt »Mit der Zeit zu gehen«.PATENT CLAIM: Projector with a protective housing which encloses the operating and optical parts and which remains connected to the projector even when the projector is in operation, characterized in that the position of the protective housing can only be changed for the transition to the operating state in such a way that all of the operating parts are exposed , but the lamp housing remains enclosed in such a way that it is protected against contact by the protective housing. To distinguish the subject matter of the application from the state of the art, the following publications were considered in the granting procedure: French patent specification ...
