Description
Lichtreklamevorrichtung zur Darstellung von Bewegungsvorgängen Zur Verstärkung des Bewegungseindruckes bei der Lichtreklamevorrichtung nach Patent 494644 wird gemäß der Erfindung nicht der Projektionsapparat, sondern der Projektionsschirm = innerhalb des vorn durch eine Glasscheibe 2 oder ein Tageslichtgitter abgeschlossenen Gehäuses 3 hin und her bewegt. Hierdurch erhält das Bild selbst noch eine Eigenbewegüng, so daß der Bewegungsvorgang, das Hervorkommen aus der Tiefe, ein tatsächlicher wird, der durch die bisher nur vorgetäuschte Bewegung verstärkt wird.Illuminated advertising device for the display of movement processes Enhancement of the impression of movement in the light advertising device according to the patent 494644 is not the projection apparatus, but the projection screen according to the invention = within the closed at the front by a pane of glass 2 or a daylight grille Housing 3 moved back and forth. This gives the picture its own movement, so that the process of movement, the emergence from the depths, becomes an actual one, which is reinforced by the previously only simulated movement.
Ein weiterer Vorteil ist, daß die Platte 4 bzw. die Bildscheibe g in einer Ebene bleiben. Hierdurch wird die Möglichkeit gewonnen, auf einfache Weise mittels mehrerer unrunden Scheiben 6 und der mit entsprechenden Nocken versehenen Bildrahmen 7 verschiedenartige und wechselnde Bewegungen der Bilder hervorzurufen. Der Antriebsmotor und die Übertragung sind punktiert angedeutet.Another advantage is that the plate 4 or the display disc g stay in one plane. This gives the possibility in a simple way by means of several non-circular disks 6 and those provided with corresponding cams Picture frame 7 to cause different and changing movements of the pictures. The drive motor and the transmission are indicated by dotted lines.
Werden Figuren oder Gegenstände auf schwarzem Grunde verwendet, so wird bei der Erfindung eine besonders starke Wirkung erreicht, da die Bilder hierdurch plastisch aus der dunklen Tiefe des Apparates geheimnisvoll heranschweben.If figures or objects are used on a black background, so a particularly strong effect is achieved in the invention, since the images thereby three-dimensionally, mysteriously floating up from the dark depths of the apparatus.
Bekanntlich ist ein von gleicher Platte projiziertes kleines Bild bedeutend heller als ein großes, während umgekehrt ein aus der Ferne kommender Gegenstand um so heller erscheint, je näher er kommt. Um diese Wirkung zu erreichen, wird erfindungsgemäß die Bildhelligkeit beim Kleinerwerden in unmittelbarer Kupplung mit der Bewegung abgeblendet und umgekehrt. Im vorliegenden Beispiel geschieht dies durch eine Irisblende 8, die durch die Stange 9 gesteuert wird. Statt dessen kann jedoch auch ein Stufenfilter verwendet werden oder durch allmähliches Einschalten eines Widerstandes die Lichtquelle verdunkelt werden.As is well known, there is a small image projected from the same plate significantly brighter than a large one, while conversely an object coming from a distance the closer it gets, the brighter it appears. In order to achieve this effect, according to the invention the brightness of the image as it becomes smaller in direct coupling with the movement dimmed and vice versa. In the present example, this is done using an iris diaphragm 8 which is controlled by the rod 9. Instead, however, a step filter can also be used or by gradually turning on a resistor the light source be darkened.
Eine weitere Verbesserung ist bei der Scharfeinstellung getroffen worden. Da bekanntlich bei stärkerer Vergrößerung die Einstellung besonders empfindlich ist und sich Ungenauigkeiten der Kurve oder der Übertragung sehr bemerkbar machen, ist die Kurve =o mit dem die Optik =i haltenden Pendelarm x2 zu einem Winkelhebel verbunden. Dadurch erhält der Einstellhebel seine größte Länge und damit seine größte Genauigkeit bei der stärksten Vergrößerung.Another improvement has been made with the focus setting been. As is well known, the setting is particularly sensitive with higher magnification and inaccuracies in the curve or the transmission are very noticeable, the curve = o with the pendulum arm x2 holding the optics = i to an angle lever tied together. This gives the setting lever its greatest length and thus its greatest Accuracy at the highest magnification.
