Description
Die Erfindung bezieht sich auf den Gewichtsausgleich einer Jalousie. t Es sind bereits Laschenketten bekannt geworden, die als Gegengewicht für den herabgelassenen Teil einer Jalousie dienen und sich beim Aufrollen der Jalousie allmählich auf den Boden aufsetzen. Diese Ketten können jedoch nicht vollkommen die Veränderung des jeweiligen Gewichtes der Jalousie ausgleichen. Während nämlich durch die dauernde Änderung des Durchmessers der Aufwickelrolle und durch die ungleichmäßige Ausbildung der Jalousie das Gewicht des herabhängenden Teiles der Jalousie sich nicht stetig, sondern sogar sprunghaft ändern kann, ändert sich das bekannte Gegengewicht stetig, da sich stets nur gleich schwere Teile des Gegengewichtes auf dem Boden absetzen.The invention relates to the weight compensation of a blind. t Chain-link chains have already become known that serve as a counterweight for the lowered part of a blind and gradually come to rest on the floor when the blind is rolled up. However, these chains cannot completely compensate for the change in the weight of the blind. While the constant change in the diameter of the take-up roll and the uneven design of the blind, the weight of the hanging part of the blind cannot change steadily but even abruptly, the known counterweight changes steadily, since only parts of the counterweight that are equally heavy are always changing set down on the floor.
Der Erfindung gemäß sind die einzelnen Lamellenpakete der Kette entsprechend dem durch das Gewicht des jeweilig herabhängenden Teiles der Jalousie ausgeübten Kraftmoment nacheinander verschieden schwer ausgebildet, so daß die Gewichtsänderung des herabhängenden Teiles der Jalousie in jeder Art, also auch bei sprunghaften Änderungen ausgeglichen werden kann.According to the invention, the individual plate packs of the chain are according to the moment of force exerted by the weight of the respective hanging part of the blind successively different heavy, so that the weight change of the hanging part of the blind in each Art, so it can also be compensated for sudden changes.
Die Zeichnung stellt als Ausführungsbeispiel ein Teilstück einer solchen nach der Erfindung ausgebildeten Laschenkette dar.As an exemplary embodiment, the drawing represents a portion of such a device according to the invention formed link chain.
Ein Glied dieser Gegengewichtskette besteht aus einzelnen Lamellen^ und B, die ■durch geeignete Stifted zusammengehalten werden. Um nun einen Gleichgewichtszustand zwischen einer in beliebiger Lage befindlichen Jalousie und dem Gegengewicht zu erhalten, kann je nach Bedarf das Gewicht der einzelnen Glieder dadurch verändert werden, daß man weitere Lamellen / und /' hinzufügt, die durch Stifte ν oder andere geeignete Mittel befestigt werden. Nach einer weiteren Umdrehung der Auswickelrolle der Jalousie gleicht man wieder das Gegengewicht auf die beschriebene Weise aus und kann dadurch in jeder Lage der Jalousie stets eine genaue Anpassung des Gegengewichtes erreichen, gleichgültig, welche Gewichtsveränderung der herabhängende Teil der Jalousie in den verschiedenen Lagen des Aüfwickelns erfährt.One link of this counterweight chain consists of individual slats ^ and B, which are held together by suitable pins. In order to obtain a state of equilibrium between a blind in any position and the counterweight, the weight of the individual links can be changed as required by adding more slats / and / ' which are attached by pins ν or other suitable means . After a further rotation of the roller of the blind, the counterweight is balanced again in the manner described and can thus always achieve an exact adjustment of the counterweight in every position of the blind, regardless of the change in weight of the hanging part of the blind undergoes in the different positions of the unwinding .
An Stelle des Anfügens weiterer Lamellen an die Kettenglieder kann man auch den Ausgleich dadurch herbeiführen, daß man zur Erhöhung des Gegengewichtes einzelne Lamellen A und B bei entsprechender Verringerung des Winkels α verlängert oder aber ihre Lage zwecks Gewichtsverminderung bei Vergrößerung des Winkels vermindert.Instead of adding further lamellas to the chain links, compensation can also be brought about by lengthening individual lamellas A and B with a corresponding reduction in the angle α to increase the counterweight or by reducing their position to reduce weight when increasing the angle.
Ferner kann man auch das Gegengewicht der Kette dadurch dem jeweiligen Gewichte der Jalousie anpassen, daß man die einzelnen <5o Lamellen aus verschieden schwerem Material, z. B. Stahl, Blei ο. dgl., herstellt.Furthermore, you can also counterbalance the chain by adding the respective weights adjust the blind so that the individual <5o slats are made of different heavy materials, z. B. steel, lead ο. Like., manufactures.
