Description
Abblendevorrichtung für Luftschutzzwecke auf Kaminen usw. Die Erfindung betrifft eine Abblendevorr ichtung für Luftschutzzwecke gemäß Patent 685762. Blind device for air protection purposes on chimneys, etc. The invention relates to a blind device for air protection purposes according to patent 685762.
Im Hauptpatent ist eine Abblendevorrichtung für Luftschutzzwecke für Kamine usw. gezeigt, mit der die' Abschirmung durch wenigstens zwei Reihen von winklig geformten, senkrecht -angeordneten, schindelartig, jedoch mit Zwischenräumen sich überdeckenden Stäben erreicht wird. An Stelle der winklig geformten Stäbe können. indessen auch andere Profile gewählt werden: Diese Profile, z. B. in Halbkreis-, U-, I- oder Z-Form, müssen aber so angeordnet sein, daß dem Lichtstrahl kein unmittelbarer Weg frei steht, die Abgase sich indessen durch die Zwischenräume zwischen den einzelnen Stäben ins Freie hindurchwinden können.In the main patent, a screen device for air protection purposes for chimneys, etc. is shown, with which the 'shielding is achieved by at least two rows of angled, vertically -arranged, clapboard-like, but with gaps overlapping rods. Instead of the angled bars you can. however, other profiles are also selected: These profiles, e.g. B. in a semicircle, U, I or Z shape, but must be arranged so that the light beam is no direct path free, but the exhaust gases can wind through the spaces between the individual rods to the outside.
Der Vorteil der neuen Ausführung besteht darin, daß mit stets greifbaren Profilen die Abdeckung erstellt werden kann und daß gegebenenfalls auch mit einer geringeren Anzahl von entsprechend breiteren Stäben auszukommen ist. Bei Verwendung von Z-Eisen oder ähnlichen Profilen ist die Abblendung mit einer Reihe von Stäben vorteilhaft zu erreichen, so daß_ die Aufhängekonstruktion vereinfacht wird.The advantage of the new design is that it is always within reach Profiles the cover can be created and that optionally also with a a smaller number of correspondingly wider rods can be managed. Using of Z-irons or similar profiles is dimming with a number of rods to achieve advantageous, so that_ the suspension structure is simplified.
Einige Ausführungsbeispiele sind in den Zeichnungen Fig. z bis 6 wiedergegeben. Es zeigen Fig. i eine Abdeckung aus zwei halbkreisförmig gebogenen Blechen, Fig. z eine Abdeckung aus einer Reihe von Z-Eisen; Fig. 3 deutet an, daß die Z-Eisen auch in mehreren Reihen angeordnet werden können. Weiter zeigen Fig. 4 eine Abdeckung aus zwei Reihen U-Eisen, Fig. 5 eine Kombination aus I-Eisen und Fig.6 eine solche aus Z- und U-Eisen.Some exemplary embodiments are shown in the drawings, FIGS. FIG. 1 shows a cover made of two semicircular curved metal sheets, FIG. Z shows a cover made from a row of Z-irons; Fig. 3 indicates that the Z-irons can also be arranged in several rows. Furthermore, Fig. 4 shows a cover made of two rows of U-irons, Fig. 5 shows a combination of I-irons and Fig. 6 a combination of Z- and U-irons.
