Description

Bildwerfer. Gegenstand der Erfindung ist ein Bildwerfer, der äuf einem in der Höhe einstellbaren Stativ um eine horizontale Achse schwenkbar gelagert ist. Die Neigung aus der wagerechten in die senkrechte Stellung erfolgt durch einen Stellschieber, dessen geschlitzte Enden mit Stiften, die sich am Gehäuse des Bildwerfers befinden, und Bogenschlitzen in Klen den Bildwerfer tragenden Böcken zusammenwirken.Projector. The subject of the invention is an image projector, the äuf one Height-adjustable tripod is pivotably mounted about a horizontal axis. The inclination from the horizontal to the vertical position is carried out by means of an adjusting slide. its slotted ends with pins that are located on the housing of the projector, and arc slots in clusters of frames supporting the projector.

Die Zeichnung zeigt eine beispielsweise Ausführungsform, und zwar Abb. i in Seitenansicht und Abb. 2 in Aufsicht.The drawing shows an example embodiment, namely Fig. I in side view and Fig. 2 in top view.

Die als Auflage dienende Grundplatte a ist vorteilhaft finit der Apparattragplatte b durch Scherenspreizen c verbunden. Diese sind in den festen Lagern a1 und b1 gelenkig befestigt und gleiten mit den Spreizerienden cl und c2 in ,Schlitzen a2 und b-. Die Spreizenenden cl und c2 sind durch Gestänge c? so miteinander gekuppelt, daß ihre Bewegung durch den Trieb d gleichmäßig erfolgt. Die finit einer Aussparung b3 versehene Tragplatte b nimmt den Bildwerfer f auf, der mittels der Zapfena2 in den Böcken c und e1 schwenkbar befestigt ist. Kreisbogenförmige Schlitze e2 in den Böcken und senkrechte Schlitze g in den Teilen g1 des Einstellschiebers g2 wirken mit den Stiften f1 des Bildwerfers derart zusammen, daß beim Schwenkendes Stellhebels il uni die Achse i2 der 13il"dwerfer beliebig geneigt werden kann. Durch ein federndes Sperrorgan i`° im Knopf il, das in die Aussparungen k1 der Skala k eingreifen kann, ist die Neigung des Bildwerfers in jeder gewünschten Winkellage zur Grundplatte einstellbar. Der Stellhebel il ist mit dem Einstellschieber 92 mittels des Stiftes g3, der in dem Schlitze i. gleiten kann, verbunden.The base plate a serving as a support is advantageously finite to the apparatus support plate b connected by spreading scissors c. These are articulated in the fixed bearings a1 and b1 attached and slide with the spreader ends cl and c2 in, slots a2 and b-. The spreader ends cl and c2 are connected by rods c? so coupled that their movement takes place evenly through the drive d. The finite of a recess b3 provided support plate b takes on the projector f, which by means of the pin a2 in the brackets c and e1 is pivotally attached. Arc-shaped slots e2 in the Blocks and vertical slots g in the parts g1 of the adjusting slide g2 act with the pins f1 of the projector so that when pivoting the control lever il uni the axis i2 of the projector can be inclined at will Locking element i` ° in the button il, which can engage in the recesses k1 of the scale k, is the inclination of the projector in any desired angular position to the base plate adjustable. The adjusting lever il is connected to the adjusting slide 92 by means of the pin g3, which is in the slot i. can slide connected.
