Description
Anmelder: Wolfgang BaudischApplicant: Wolfgang Baudisch
Die Erfindung betrifft eine Vorrichtung zum Abbremsen des Aufrollvorganges (Aufrollbremse) von Springrollos zur Verwendung entweder als Nachrüstsatz für bestehende Rollos oder als regulärer Bestandteil von neuen Erzeugnissen.The invention relates to a device for braking the rolling-up process (roll-up brake) of spring roller blinds for use either as a retrofit kit for existing roller blinds or as a regular component of new products.
Das Prinzip eines Springrollos besteht darin, daß beim Abrollen (Verdunkeln) eine eingebaute Feder gespannt wird, die nach Entriegeln einer Sperrklinke durch ruckartiges Ziehen am Rollo dieses selbsttätig wieder aufrollt. Durch mehr oder weniger starkes Aufrollen vor dem Montieren des Rollos kann außerdem die Grundspannung der Feder so eingestellt werden, daß sie ausreichend stark ist. um das Rollo vollständig aufzuwickeln. Da das Rollo aber am Schluß der Aufwickelphase den größten Drehimpuls hat. würde es über die Endstellung hinausrollen, was schlimmstenfalls zur Beschädigung führen kann, wenn es nicht von Hand aus abgebremst oder angehalten würde. Das Abbremsen von Hand hat wiederum den Nachteil, daß dabei der Sperrmechanismus vorzeitig betätigt werden kann, so daß das Rollo in einer Zwischenstellung stehen bleibt, von der aus es manchmal nicht mehr gelingt die Sperrklinke wieder zu entriegeln weil die Federspannung dafür schon zu schwach ist. Das heißt, daß der ganze Vorgang dannn nochmals von unten an wiederholt werden muß.The principle of a spring roller blind is that when it is unrolled (darkened), a built-in spring is tensioned, which automatically rolls the blind back up again after a locking pawl is released by pulling the blind sharply. By rolling it up more or less strongly before fitting the blind, the basic tension of the spring can also be adjusted so that it is strong enough to completely roll the blind up. However, since the blind has the greatest angular momentum at the end of the winding phase, it would roll beyond the end position, which in the worst case could lead to damage if it is not braked or stopped by hand. Braking by hand has the disadvantage that the locking mechanism can be activated prematurely, so that the blind stops in an intermediate position from which it is sometimes no longer possible to unlock the locking pawl again because the spring tension is already too weak. This means that the whole process then has to be repeated from the bottom up.
AufgabeTask
Der Erfindung gemäß Anspruch 1 liegt daher die Aufgabe zugrunde, den Aufrollvorgang vollautomatisch und exakt in der Endstellung abzubremsen, wobei nach Entriegeln der Sperre kein zurückhalten mehr notwendig ist. Dies wird durch Bremsklötze erreicht, die ca. im letzten Drittel der Aufwickelphase durch Reibung eine Bremskraft erzeugen, die umso stärker wird, je dicker das aufgewickelte Rollo wird. Bei richtiger Anfangsjustierung der Federkraft wie oben beschrieben und des Abstandes zwischen Rollo 1 und Bremsklotz 2 ist es möglich, ein ganz exaktes und sanftes Abbremsen in der Endstellung zu erreichen.The invention according to claim 1 is therefore based on the task of braking the rolling-up process fully automatically and precisely in the end position, whereby after the lock is unlocked, no more holding back is necessary. This is achieved by brake blocks which, in the last third of the winding phase, generate a braking force through friction, which becomes stronger the thicker the rolled-up roller blind becomes. With the correct initial adjustment of the spring force as described above and the distance between roller blind 1 and brake block 2, it is possible to achieve a very precise and gentle braking in the end position.
Vorteilhafte Ausgestaltungen der Erfindung sind in den Ansprüchen 2 bis 1 2 angegeben.Advantageous embodiments of the invention are specified in claims 2 to 12.
Die Keilform nach Anspruch 2 ermöglicht leichtes Verstellen durch vertikales Verschieben des Bremsklotzes 2.The wedge shape according to claim 2 enables easy adjustment by vertically moving the brake block 2.
Die konkave Form nach Anspruch 3 (Fig. 2) ergibt größere Bremskraft durch größere Reibungsfläche.The concave shape according to claim 3 (Fig. 2) results in greater braking force due to a larger friction surface.
Elastische Bremsklötze oder Lagerung nach den Ansprüchen 4 oder 5 vermindern die unerwünschte Bremswirkung beim Abrollen, insbesondere wenn ein Material mit sehr langsamer elastischer Formänderung verwendet wird, wie Schaumstoff. Dieses schrumpft durch den Anpreßdruck des Rollo im aufgewickelten Zustand langsam ein, so daß die Bremswirkung beim Abrollen minimal ist. Im abgerollten Zustand dehnt es sich aber langsam wieder aus, so daß die volle Bremswirkung beim Einrollen zur Verfügung steht.Elastic brake blocks or bearings according to claims 4 or 5 reduce the undesirable braking effect when rolling, especially when a material with very slow elastic deformation is used, such as foam. This slowly shrinks due to the contact pressure of the roller blind when rolled up, so that the braking effect when rolling is minimal. When unrolled, however, it slowly expands again so that the full braking effect is available when rolling up.
Die Ansprüche 6 und 7 ergeben höhere Bremskraft durch Aufbringen einer rauhen Bremsfläche 4.Claims 6 and 7 result in higher braking force by applying a rough braking surface 4.
Befestigung nach Anspruch 8 eignet sich vor allem zur Nachrüstung, während die nach 9 oder 1 0 vor allem für Neukonstruktionen anwendbar ist.Fastening according to claim 8 is particularly suitable for retrofitting, while that according to 9 or 1 0 is mainly applicable for new constructions.
Ansprüche 11 und 1 2 ermöglichen die Feineinstellung des Abstandes zwischen Rollo 1 und Bremsklotz 2 in Verbindung mit Anspruch 2. Auch bei Befestigung nach Anspruch 1 0 kann die Feineinstellung mittels Langlöchern in den Rollohalterungen 3 vorgenommen werden.Claims 11 and 12 enable the fine adjustment of the distance between the roller blind 1 and brake block 2 in conjunction with claim 2. Even with fastening according to claim 10, the fine adjustment can be carried out by means of elongated holes in the roller blind brackets 3.
Ein Ausführungsbeispiel der Erfindung ist in Figur 1 dargestellt. In Figur 1 ist mit 1 das Springrollo im abgewickelten Zustand, mit 2 ein Bremsklotz, an dessen Oberfläche sich die Bremsfläche 4 befindet, und mit 3 die Rollohalterung bezeichnet.An embodiment of the invention is shown in Figure 1. In Figure 1, 1 designates the spring roller blind in the unwound state, 2 designates a brake block on the surface of which the braking surface 4 is located, and 3 designates the roller blind holder.
VorteileAdvantages
Der Vorteil der Erfindung besteht darin, daß eine erhebliche Verbesserung des Bedienungskomforts sowohl bei schon installierten als auch bei neuen Springrollos mit geringstem technischen Aufwand erreicht wird. Wenn man bedenkt, daß solche Rollos täglich mindestens ein mal wenn nicht öfter auf- und zugezogen werden, daß in einer Wohnung oft mehrere Rollos installiert sind und daß ohne Aufrollbremse dabei die eingangs geschilderten Schwierigkeiten auftreten können, ist leicht zu erkennen, welche wirtschaftliche Bedeutung dieser Erfindung zuzurechnen ist.The advantage of the invention is that a significant improvement in the ease of use is achieved with minimal technical effort for both already installed and new roller blinds. When you consider that such blinds are opened and closed at least once a day , if not more often, that several blinds are often installed in a home and that the problems described at the beginning can arise without a roller brake, it is easy to see the economic importance of this invention.
