Es sind bereits Schattendecken bekannt, bei welchen zwei übereinanderliegende Reihen von Schatten brettern aufeinander verschiebbar angeordnet sind derart, daß Lichtschlitze entstehen oder verdeckt werden. Um z. B. Treibkästen das erforderliche Licht regelbar zuführen zu können, sind die Lichtschlitze dadurch veränderlich, daß die Bretter an Schienen gleitend befestigt sind, oder daß alle oderThere are already known shade ceilings in which two superimposed rows of Shade boards are slidably arranged on top of one another in such a way that slits of light arise or be covered. To z. B. sifting boxes supply the required light controllably to be able to, the light slits are variable in that the boards on rails are slidably attached, or that all or
ίο nur die Hälfte der Bretter gedreht werden können.ίο only half of the boards are turned can.
Diesen bekannten Schatten gegenüber unterscheidet sich die Decke gemäß vorliegender Erfindung dadurch, daß zwei übereinander liegende Reihen von Schattenbrettern durch ein Verbindungsglied schwingend miteinander verbunden sind, so daß sie durch Kettenzug parallel zueinander verschoben und beliebig eingestellt werden können. Auf der Zeichnung ist die Decke dargestellt, und zwar zeigt Fig. 1 die Decke in geöffnetem Zustande, die Stäbe α und b aufeinanderliegend. Fig. 2 stellt die Decke in geschlossenem Zustande dar. Fig. 3 zeigt das Aufrollen der Decke, während Fig. 4 die Decke in einer Mittelstellung zeigt.The ceiling according to the present invention differs from these known shadows in that two rows of shadow boards lying one above the other are swingingly connected to one another by a connecting link, so that they can be moved parallel to one another by a chain hoist and adjusted as required. In the drawing, the ceiling is shown, namely Fig. 1 shows the ceiling in the open state, the bars α and b lying on top of one another. Fig. 2 shows the cover in the closed state. Fig. 3 shows the rolling up of the cover, while Fig. 4 shows the cover in a central position.
α und b sind die beiden Reihen von Schattenbrettern, die flach hergestellt, aber auch jeden beliebigen Querschnitt haben können, z. B1 prismatisch. Die obere Reihe der Bretter α hängt an der Zugkette k1, die untere an der Kette k2. Beide Ketten können ersetzt werden durch um die Stäbe gezogene Metallglieder und Zwischenglieder, ohne das Wesen der Erfindung zu beeinflussen. α and b are the two rows of shadow boards that are made flat, but can also have any cross-section, e.g. B 1 prismatic. The top row of boards α hangs on the pulling chain k 1 , the bottom row on the chain k 2 . Both chains can be replaced by metal links and intermediate links drawn around the rods without affecting the essence of the invention.
Die Verbindung beider Reihen α und b mitr einander zwecks Feststellung und Begrenzung der Beweglichkeit der Bretter bildet eine Anzahl schwingende Hebel h. Dieselben verbinden je zwei übereinanderliegende Bretter miteinander und veranlassen ihre parallele Ver-Schiebung zueinander, sobald man entweder an der unteren oder der oberen Kette k1 oder A2 zieht, die beide durch den Doppelhebel d miteinander verbunden sind.The connection of the two rows α and b with each other for the purpose of determining and limiting the mobility of the boards forms a number of swinging levers h. They connect two boards one on top of the other and cause their parallel displacement to one another as soon as one pulls either the lower or the upper chain k 1 or A 2 , both of which are connected to one another by the double lever d.
Da nun besondere Bewegungsvorrichtungen, Schnüre, Stangen oder steife Gelenke bei dieser Schutzdecke nicht vorhanden sind, so kann dieselbe leicht eng zusammengerollt werden, da die Hebel h zwischen den Stäben liegen (Fig. 3). Die Hebel h kann man sich auch als Kettenglieder, umgebogene Ösen oder als Ringe denken.Since there are no special movement devices, cords, rods or rigid joints in this protective cover, it can easily be rolled up tightly because the levers h are between the rods (FIG. 3). The lever h can also be thought of as chain links, bent eyelets or rings.
