Description

Die vorliegende Erfindung bezieht sich auf eine Sperreinrichtung gemäß dem Oberbegriff des Patentanspruchs 1.The present invention relates to a locking device according to the preamble of patent claim 1.

Eine solche Sperreinrichtung ist für Rafflamellenstores aus der DE-A 35 44 540 bekannt.Die Sperrwirkung tritt hier nur bei einer bestimmten Schwenklage ein bzw. sie ist nur bei geschlossenem Lamellenpanzer wirksam. Bei Rafflamellenstores ist indessen eine Sperrwirkung nicht nur bei völliger Verdunkelung (Schließstellung), sondern auch bei mehr oder weniger stark geneigten Lamellen erwünscht.Such a locking device is known for roman blinds from DE-A 35 44 540. The locking effect occurs here only in a certain swivel position or it is only effective when the slat armor is closed. In the case of Roman blinds, however, a blocking effect is desired not only in the case of complete darkening (closed position), but also in the case of slats that are more or less inclined.

Die vorliegende Erfindung stellt sich die Aufgabe, eine Sperreinrichtung der erwähnten Art derart zu gestalten, daß sie unabhängig von der Schwenklage der Lamellen den Store gegen ein unbefugtes Anheben sichert. Erfindungsgemäß wird diese Aufgabe gelöst durch die kennzeichnenden Merkmale des Anspruchs 1.The present invention has for its object to design a locking device of the type mentioned that it secures the store against unauthorized lifting regardless of the pivoting position of the slats. According to the invention, this object is achieved by the characterizing features of claim 1.

Anhand der beiliegenden schematischen Zeichnung wird die Erfindung beispielsweise erläutert. Es zeigen:

  • Fig. 1 eine Ansicht eines geschlossenen Raffiamellenstore oder Faltrolladens von außen,
  • Fig. 2 einen Schnitt längs der Linie 11-11 in Fig. 1 in vergrößerter Darstellung,
  • Fig. 3 einen Schnitt längs der Linie 111-111 in Fig. 4,
  • Fig. 4 eine gleiche Darstellung wie Fig. 2 in anderer Betriebsstellung des Stores und
  • Fig. 5 eine Ansicht in Richtung des Pfeiles V in Fig. 2, wobei die Seitenführung weggelassen ist.
The invention is explained, for example, with the aid of the attached schematic drawing. Show it:
  • 1 is a view of a closed Raffiamellenstore or folding roller shutter from the outside,
  • 2 shows a section along the line 11-11 in Fig. 1 in an enlarged view,
  • 3 shows a section along the line 111-111 in FIG. 4,
  • Fig. 4 shows the same representation as Fig. 2 in a different operating position of the store and
  • Fig. 5 is a view in the direction of arrow V in Fig. 2, with the side guide is omitted.

Der prinzipielle Aufbau eines Lamellenstores oder einer Faltjalousie wird anhand der Fig. 1 beschrieben. Sie weist zwei Seitenführungen 1 auf, die an der Leibung 2 der Fensteröffnung befestigt sind. Die Seitenführungen 1 haben im wesentlichen ein U-förmiges Querschnittprofil, wobei die Schenkelenden gegeneinander abgewinkelt sind und einen vertikalen Führungsschlitz bilden. Der Lamellenbehang besteht aus horizontalen Lamellen 3. Von diesen Lamellen ist u.a. die unterste seitlich mit Achsstummeln 4 in den Führungsschlitzen der Seitenführungen 1 vertikal verschiebbar gelagert. In einer über der Fensteröffnung im Mauerwerk vorhandenen Ausnehmung 5 ist die Aufzugswelle 6 mit den beiden Aufzugstrommeln 7 drehbar gelagert. Sie ist durch übliche, nicht dargestellte Antriebsmittel antreibbar. Die auf den Aufzugstrommeln 7 aufwickelbaren Aufzugsbänder 8 sind in den seitlichen Führungen 1 zu der untersten Lamelle geführt, welche daran indirekt (d.h. via Gewicht und Führungskörper) aufgehängt ist.The basic structure of a slat blind or a folding blind is described with reference to FIG. 1. It has two side guides 1 which are attached to the reveal 2 of the window opening. The side guides 1 essentially have a U-shaped cross-sectional profile, the leg ends being angled toward one another and forming a vertical guide slot. The slat curtain consists of horizontal slats 3. the bottom with axially stub 4 in the guide slots of the side guides 1 vertically slidably mounted. The elevator shaft 6 with the two elevator drums 7 is rotatably mounted in a recess 5 above the window opening in the masonry. It can be driven by conventional drive means, not shown. The elevator belts 8 that can be wound on the elevator drums 7 are guided in the lateral guides 1 to the lowest slat, which is suspended indirectly (i.e. via weight and guide body).

In jeder Seitenführung 1 ist eine Sperreinrichtung vorhanden. Diese sind gleich ausgebildet, so daß nur eine hiervon beschrieben wird. Die Sperreinrichtung weist im wesentlichen einen Führungskörper 9, einen Gewichtskörper 10 und einen Sperrkörper 22 auf, die in der Seitenführung 1 vertikal verschiebbar geführt sind.A locking device is provided in each side guide 1. These are identical, so that only one of them is described. The locking device essentially has a guide body 9, a weight body 10 and a locking body 22, which are guided in the side guide 1 so as to be vertically displaceable.

Der Führungskörper 9 ist gehäuseartig gestaltet. Zwei parallele Seitenwände 11 sind durch drei Querwände 12, 13, 14 verbunden. Die Seitenwände 11 bilden mit der Querwand 13 ein kreisabschnittförmiges. Auflager 15 für den Achsstummel 4. Die Querwand 12 ist mit einer federnden, gegen das Auflager 15 gerichteten Zunge 16 versehen, die den Achsstummel 4 auf dem Auflager 15 hält. Das Einbringen des Achsstummels 4 in das Auflager 15 geschieht dadurch, daß er zwischen die Querwand 13 und die Zunge 16 gedrückt wird. Diese weicht dabei so lange nach außen weg, bis der Achsstummel 4 auf dem Auflager 15 aufliegt. In dieser Stellung federt die Zunge zurück und hält ihn auf dem Auflager 15. Die gegenseitig beabstandeten Querwände 13 und 14 bilden einen Schlitz 17, durch den das Aufzugsband 8 hindurch geführt und mit dem freien unteren Ende am Gewichtskörper 10 befestigt ist. Die Seitenwände 11 bilden ferner mit der Querwand 14 und einem Quersteg 18 eine Kammer 19, die nach unten gegen den Gewichtskörper 10 mittels einer Durchbrechung 20 geöffnet ist. Diese Kammer 19 ist zudem offen gegen die Seitenführung 1. Die Querwand 14 ist mit zwei Rippen 21 versehen, welche mit der zugewandten Wand der Seitenführung 1 nach unten konvergieren und deren Schrägflächen mit einem harten, vorzugsweise metallischen Belag 24 versehen sind. In dieser Kammer 19 ist ein zylindrischer Sperrkörper 22 frei beweglich gelagert, der in einer oberen Endlage zumindest von einer der beiden Wände 1 bzw. 14, 21 so beabstandet ist, daß kein Reibkontakt besteht, wogegen er in einer unteren Endlage mit beiden Wänden Reibschluß hat.The guide body 9 is designed like a housing. Two parallel side walls 11 are connected by three transverse walls 12, 13, 14. The side walls 11 form with the transverse wall 13 a circular section. Support 15 for the stub axle 4. The transverse wall 12 is provided with a resilient tongue 16 directed against the support 15 which holds the stub axle 4 on the support 15. The stub axle 4 is introduced into the support 15 by pressing it between the transverse wall 13 and the tongue 16. This deviates outward until the stub axle 4 rests on the support 15. In this position, the tongue springs back and holds it on the support 15. The mutually spaced transverse walls 13 and 14 form a slot 17, through which the elevator belt 8 is guided and fastened to the weight body 10 with the free lower end. The side walls 11 also form, with the transverse wall 14 and a transverse web 18, a chamber 19 which is opened downwards against the weight body 10 by means of an opening 20. This chamber 19 is also open to the side guide 1. The transverse wall 14 is provided with two ribs 21 which converge downward with the wall of the side guide 1 facing and the inclined surfaces of which are provided with a hard, preferably metallic coating 24. In this chamber 19, a cylindrical locking body 22 is freely movable, which is spaced in an upper end position from at least one of the two walls 1 and 14, 21 so that there is no frictional contact, whereas in a lower end position it has frictional engagement with both walls .

Als Verlängerung der Seitenwände 11 nach unten ist der Führungskörper 9 weiter mit zwei Führungsfingern 23 versehen. Zwischen diesen Führungsfingern 23 ist der Gewichtskörper 10 vertikal verschiebbar gelagert, wobei die Führungsfinger 23 in entsprechenden Ausnehmungen am Gewichtskörper 10 liegen. Der Gewichtskörper nimmt eine obere, in Fig. 4 gezeigte und eine untere in Fig. 2 gezeigte Endlage ein. In der oberen Endlage liegt er gegen die unteren Stirnflächen der Wände 11 bis 14 des Führungskörpers 9 an, wogegen seine untere Endlage keine Begrenzung erfordert und durch die bauseitigen Gegebenheiten bestimmt ist. Eine nach oben gerichtete Nocke 25 des Gewichtskörpers 10 greift durch die Durchbrechung 20 hindurch. Nimmt der Gewichtskörper 10 die obere Endlage ein, stößt die Nocke 25 den Sperrkörper 22 soweit nach oben, daß dieser mit wenigstens einer der beiden konvergierenden Flächen 1, bzw. 14, 21 außer Reibkontakt ist. In einer unteren Endlage des Gewichtskörpers 10 ist die Nocke 25 soweit aus der Kammer 19 zurückgezogen, daß der Sperrkörper 22 mit beiden konvergierenden Flächen in Reibschluß steht. Wirkt in dieser unteren Endlage des Gewichtskörpers 10 eine vertikal nach oben gerichtete Kraft auf den Achsstummel 4, so kann der Führungskörper 9 wegen des Reibschlusses des Sperrkörpers 22 nicht hochgeschoben werden. Dies unabhängig von der Drehlage des Achsstummels 4. Der Belag 24 verhindert eine plastische Verformung der Rippen 21, so daß sich der Sperrkörper auch nach einer längeren Belastung aus seiner Sperrstellung schieben läßt.As an extension of the side walls 11 downward, the guide body 9 is further provided with two guide fingers 23. Between these guide fingers 23, the weight body 10 is mounted so as to be vertically displaceable, the guide fingers 23 being located in corresponding recesses on the weight body 10. The weight body assumes an upper end position shown in FIG. 4 and a lower end position shown in FIG. 2. In the upper end position it lies against the lower end faces of the walls 11 to 14 of the guide body 9, whereas its lower end position does not require any limitation and is determined by the on-site conditions. An upwardly directed cam 25 of the weight body 10 extends through the opening 20. If the weight body 10 assumes the upper end position, the cam 25 pushes the locking body 22 upwards to such an extent that it is out of frictional contact with at least one of the two converging surfaces 1 and 14, 21, respectively. In a lower end position of the weight body 10, the cam 25 is withdrawn from the chamber 19 to such an extent that the locking body 22 is in frictional engagement with both converging surfaces. If a vertically upward force acts on the stub axle 4 in this lower end position of the weight body 10, the guide body 9 cannot be pushed up because of the frictional engagement of the locking body 22. This is independent of the rotational position of the stub axle 4. The coating 24 prevents plastic deformation of the ribs 21, so that the locking body can be pushed out of its locking position even after a prolonged load.

Während des Hebens und Senkens des Stores ruht der Führungskörper 9 und damit das Gewicht des Lamellenbehangs auf dem Gewichtskörper 10. Dabei greift die Nocke 25 weit in die Kammer 19 und hebt den Sperrkörper 22 aus seiner Sperrstellung. Erreicht der Store während des Senkens die tiefste Stellung, bewegt sich der Gewichtskörper 10 weiter nach unten, wodurch die Nocke 25 den Sperrkörper 22 in die Sperrstellung bewegt. Ein Anheben des Lamellenbehangs ist nun unabhängig von der Schwenklage der Lamellen nicht mehr möglich.During the lifting and lowering of the store, the guide body 9 and thus the weight of the slatted curtain rests on the weight body 10. The cam 25 reaches far into the chamber 19 and lifts the locking body 22 out of its locked position. If the store reaches the lowest position during the lowering, the weight body 10 moves further downward, as a result of which the cam 25 moves the locking body 22 into the locking position. It is now no longer possible to raise the slat blind regardless of the swivel position of the slats.

Sobald der Lamellenpanzer vollständig abgesenkt ist, beginnt der Gewichtskörper 10 zwischen den Führungsfingern 23 nach unten zu gleiten bis das Aufzugsband von der Aufzugstrommel 7 abgewickelt ist. Das Aufzugsband bleibt aufgrund des Gewichtskörpers ständig gestreckt.As soon as the slat armor is completely lowered, the weight body 10 begins to slide down between the guide fingers 23 until the elevator belt is unwound from the elevator drum 7. The elevator belt is constantly stretched due to the weight.
