Description

Schaueinrichtung für Wasserstandsanzeiger. Die Erfindung bezieht sich auf eine Schaueinrichtung für Wasserstandsanzeiger nach Patent 4o6928 und bezweckt eine Verbesse rung und Vervollständigung jener Vorrichtung.Display device for water level indicator. The invention relates to on a display device for water level indicators according to patent 4o6928 and aims an improvement and completion of that device.

An demjenigen Teil des Wasserstandsanzeigers, der die das Licht abblendenden schrägen Schilder trägt, ist ein lichtreflektierender Hilfskörper, z. B. eine farbige Glasp#brIe oder ein Prisma, oder zwei Glasperlen und zwei Prismen, oder ähnliche Lichtreflektoren, in horizontaler Lage angebracht, eins an jeder Seite der Lichtschilder, so daß das zwischen den schrägen Schildern durchscheinende Licht reflektierende Hilfskörper erleuchtet und das Betriebsniveau angibt, auf welchem der Wasserstand gehalten werden sollte. Weitere Glasperlen, Prismen oder ähnliche Hilfskörper können an dem 'Wasserstand nahe den oberen und unteren Enden angebracht werden, um die sicheren Betriebsgrenzen anzuzeigen.On the part of the water level indicator that dips the light carries oblique signs is a light-reflecting auxiliary body, e.g. B. a colored one Glass bead or a prism, or two glass beads and two prisms, or the like Light reflectors, mounted in a horizontal position, one on each side of the light shields, so that the light shining through between the oblique shields is reflective Auxiliary body lights up and indicates the operating level at which the water level should be kept. Further glass beads, prisms or similar auxiliary bodies can at the 'water level near the upper and lower ends to be attached to the display safe operating limits.

Die Erfindung ist auf der Zeichnung dargestellt.The invention is shown in the drawing.

Abb. i und 2 sind senkrecht zudinander stehende Aufrisse einer Wasserstandsglaseinrichtung mit einem Paar darauf angebrachter Glasperlen.Figs. I and 2 are vertical elevations of a water level glass device with a pair of glass beads attached to it.

Auf der Zeichnung bezeichnet A die schrägen Platten oder Segmente, die in geeigneter Weise in übereinander angeordneter Verbindung auf dem Rahmen B des Wasserstandes angeordnet und voneinander getrennt sind, damit Licht nach oben hin unmittelbar zwischen ihnen durchscheinen kann; dieses rührt von einer künstlichen Lichtquelle, z. B. von einer Birne, her, die innerhalb des Lichtreflektors C aufgehängt ist; hierbei verhindern die Seitenplatten D des Raumes, daß direktes Licht von hitten her an den Seiten eintritt.In the drawing, A denotes the inclined plates or segments which are suitably arranged in superposed connection on the frame B of the water level and separated from one another so that light can shine through directly between them upwards; this comes from an artificial light source, e.g. B. from a bulb, which is suspended within the light reflector C; in this case, the side panels D of the room prevent direct light from entering from the sides.

Wie dargestellt, ist auf dem Rahmen B, angrenzend an die schrägen Lichtschilder A, ein Paar farbiger Glasperlen E horizontal nebeneinander angebracht, die durch das Licht erleuchtet werden, das zwischen den schrägen Lichtschildern A hindurchtritt, und auf der Vorderseite des Wasserstandsanzeigers Punkte auf der horizontalen Linie darstellen, die das Wasserstandsniveau angibt, auf welchem der Wasserstand gehalten werden sollte. Weitere Glasperlen oder Prismen oder ähnlich wirkende Hilfskörper, die von derselben oder von einer anderen Farbe sein mögen, können nahe dem oberen und unteren Ende des Wasserstandes zwecks 'Anzeigung der sicheren Betriebsgrenzen angebracht werden.As shown, on the frame B, adjacent to the inclined light signs A, a pair of colored glass beads E are mounted horizontally next to each other, which are illuminated by the light that passes between the inclined light signs A , and on the front of the water level indicator points on the horizontal Draw a line indicating the water level at which the water level should be maintained. Further glass beads or prisms or similarly acting auxiliary bodies, which may be of the same or a different color, can be attached near the upper and lower end of the water level in order to indicate the safe operating limits.
