Der Hauptzweck des vorliegenden Ventilations-Vorhanges ist, wie bei den bekannten Brettchen-Vorhängen, Schutz gegen directe Sonnenstrahlen bei hinreichender Zuführung von Licht und Luft.The main purpose of the present ventilation curtain is, as with the well-known board curtains, Protection against direct sun rays with sufficient supply of light and air.
Während bei den Brettchen-Vorhängen die Regulirung der lichten Querschnitte durch Verdrehen der Brettchen bewirkt wird, geschieht dies hier durch Anordnung hinter einander liegender, gegenseitig verschiebbarer Platten oder Sprossen, von denen je zwei sich decken oder beliebig gegen einander verschoben sein können.While with the board curtains the regulation of the clear cross-sections by twisting the board is effected, this is done here by arranging one behind the other, mutually displaceable plates or Rungs, two of which can cover each other or be shifted against each other at will.
In Fig. ι ist der mit regelmäfsigen Durchbrechungen versehene sprossenartige Vorhang a in der Querstange b befestigt, schlingt sich um die bewegliche Belastungswalze c und geht nach der Rollachse d, welche durch die Schnur e bewegt wird. Da ,beim Auf- und Ablassen der innere Theil des Vorhanges still steht und nur der äufsere sich bewegt, so ist klar, dafs hierbei alle möglichen gegenseitigen Stellungen durchlaufen werden und daher die Verstellung durch die Schnur e selbst bewirkt wird.In Fig. Ι the bar-like curtain a provided with regular openings is fastened in the cross bar b , loops around the movable loading roller c and goes to the roll axis d, which is moved by the cord e . It says in establishing and releasing the inner part of the curtain, still and only the outward moving, it is clear, that in this case all the possible mutual positions are run through, and therefore the adjustment is effected by the string itself e.
In Fig. 2 ist der Vorhang in zwei getrennten Stücken ä« an den ,Rollachsen dd aufgehängt, welch letztere durch die Doppelschnur/ einzeln oder zusammen bewegt werden können, wobei wieder, wie in Fig. 1, jede gegenseitige Stellung möglich ist.In FIG. 2 the curtain is suspended in two separate pieces from the rolling axes dd , which the latter can be moved individually or together by the double cord, again, as in FIG. 1, any mutual position being possible.
Fig. 3 stellt den Vorhang in gröfserem Mafsstabe in drei verschiedenen Haüptstellungen dar, und ist daraus besonders ersichtlich, dafs sogar bei vollständiger Ueberdeckung der Luftdnrchgangs-Querschnitt nur wenig vermindert und daher die Ventilation gegenüber den bisherigen Jalousien eine bessere ist.Fig. 3 shows the curtain on a larger scale in three different main positions and it is particularly evident from this that even when the air passage cross-section is completely covered only slightly reduced and therefore the ventilation compared to the previous ones Blinds is a better one.
Zu bemerken ist noch, dafs dieser Ventilations-Vorhang sowohl zur Anwendung innerhalb als aufserhalb des Fensters sich eignet und demgemäfs der Vorhang α selbst bezüglich Materials und Beschaffenheit verschiedenartig ausgeführt sein kann.It should also be noted that this ventilation curtain is suitable for use both inside and outside the window and accordingly the curtain α itself can be designed in various ways with regard to material and properties.
