Description

Die Erfindung betrifft eine Rolljalousie insbesondere für Fenster und Türen, mit den im Oberbegriff des Patentanspruchs 1 gekennzeichneten Merkmalen.The invention relates to a roller blind, in particular for windows and doors, with the features characterized in the preamble of claim 1.

Eine derartige Jalousie ist durch die CH-A-618 495 bekannt. Um das zickzackförmige Zusammenlegen der einzelnen Leisten in einem unterhalb der Mitnehmerwelle angeordneten Raum ohne seitliche Führungen zu erreichen, sind mindestens zwei benachbarte Leisten mittels Blattfedernverbunden, die das Innere der Leisten durchsetzen.Such a blind is known from CH-A-618 495. In order to achieve the zigzag folding of the individual strips in a space arranged below the drive shaft without lateral guides, at least two adjacent strips are connected by means of leaf springs which penetrate the inside of the strips.

Aufgabe der vorliegenden Erfindung ist es, einen guten Teil der hohen Montagekosten zu vermindern, wie sie den herkömmlichen Einheiten dieser Art eigen sind.The object of the present invention is to reduce a good part of the high assembly costs that are inherent in the conventional units of this type.

Gemäss der Erfindung sind für die Gewährleistung des zickzackförmigen Zusammenlegens von gleichzeitig mindestens zwei Leisten in die gegenüberliegenden Stirnseiten mindestens zweier benachbarter Leisten ebensoviele Stopfen eingebracht, welche gegenseitig mittels elasticher Fortsätze oder Ansätze, insbesondere aus Kunststoff, Gummi oder Material mit analogen Merkmalen der Nachgiebigkeit, ineinandergreifen.According to the invention, in order to ensure the zigzag folding of at least two strips at the same time into the opposite end faces of at least two adjacent strips, as many plugs are inserted which engage one another by means of elastic extensions or approaches, in particular made of plastic, rubber or material with analogous characteristics of compliance.

Den Figuren entsprechend umfasst die Rolljalousie zwei seitliche Profile 1 die vorteilhaft in einer Legierung aus Aluminium hergestellt sind. Entgegen den herkömmlichen Profilen die lediglich ein U darstellen besitzen diese einen Aufbau und eine Bauart die derart robust ist, dass sie im oberen Bereich des Profils die Bildung eines Raumes A zur Aufnahme des Pakets P der zickzackförmig zusammengelegten Leisten 2 gewährleistet.According to the figures, the roller blind comprises two side profiles 1 which are advantageously made of an aluminum alloy. Contrary to the conventional profiles which only represent a U, they have a structure and a construction which is so robust that they ensure the formation of a space A in the upper region of the profile for receiving the package P of the strips 2 folded in a zigzag shape.

Gleichzeitig stützen die Seitenprofile 1 den Support 3 für das durch die Leisten gebildete paket so wie die Lagerstelle 4 für die drehbare Montage der Verschiebe- und Umkehrwelle 5 der Leisten.At the same time, the side profiles 1 support the support 3 for the package formed by the strips, as does the bearing point 4 for the rotatable mounting of the displacement and reversing shaft 5 of the strips.

Oberhalb des Supports 3 und der Lagerung 4 ist fest mit den zugehörigen senkrechten profilen 1 ein in der Folge eingehend beschriebener Anschlag angebracht, um ein übermässiges Abheben des Vorhanges von der Welle zu verhindern und um eine Sicherung gegen das Oeffnen der Rolljalousie, wenn diese nicht durch die eigens hierzu vorgesehene Mechanik betätigt wird, zu bilden.Above the support 3 and the mounting 4, a stop, which is described in detail below, is attached with the associated vertical profiles 1 in order to prevent the curtain from being lifted off the shaft excessively and to secure it against the opening of the roller blind when it is not through the mechanism provided for this purpose is actuated.

Die Welle 5 besitzt vorzugsweise einen vieleckigen Querschnitt, inbesondere einen quadratischen oder einen Dreieckquerschnitt. Es ist klar, dass es genügt dass eine Welle mit kreisrundem Querschnitt die vieleckigen Schnitte 6 in einigen, entlang der Welle verteilten Stellen besitzt.The shaft 5 preferably has a polygonal cross section, in particular a square or a triangular cross section. It is clear that it is sufficient that a shaft with a circular cross-section has the polygonal cuts 6 in some places distributed along the shaft.

Die Leisten sind üblicherweise aus Metall oder Kunststoffmaterial hergestellt und besitzen einen hohlen Querschnitt. Es besteht die Möglichkeit, in diese ein geeignetes Material einzuspritzen, beispielsweise Polyurethan-Schaumstoff, mit dem Ziel das Isolierungsvermögen zu erhöhen und sie gleichzeitig in ihrer Verschiebebewegung geräuscharmer zu gestalten.The strips are usually made of metal or plastic material and have a hollow cross section. It is possible to inject a suitable material into it, for example polyurethane foam, with the aim of increasing the insulating capacity and at the same time making it quieter in its displacement movement.

Die Leisten sind unter sich (Figuren 5, 6) mittels gelenkigen Verbindungsorganen 7 schwenkbar verbunden, welche in senkrechter Längsrichtung der Rolljalousie, entlang zwei oder mehr Linien, angeordnet sind.The strips are pivotally connected to one another (FIGS. 5, 6) by means of articulated connecting elements 7, which are arranged in the vertical longitudinal direction of the roller blind, along two or more lines.

Die Verbindungsorgane sind so ausgebildet, dass ihre Montage zwischen angrenzenden Leisten möglich wird und um gleichzeitig als Scharnier zwischen diesen zu dienen, und dies infolge dem Vorhandensein in diesem Verbindungsorgan eines Bügels 8 der den Leisten ein gegenseitiges Umbiegen um einen Winkel von 270° gewährleistet.The connecting members are designed so that their assembly between adjacent strips is possible and to serve as a hinge between them at the same time, due to the presence in this connecting element of a bracket 8 which ensures a mutual bending of the strips by an angle of 270 °.

Dasselbe Organ 7 wird aus einer rechteckförmigen Lamelle aus dünnem Material, z.B. Federmaterial, erhalten, wobei diese oben in 9 umgebogen ist um damit die Lagerstelle für die zwei unter sich koaxialen Grundlinien 10, 11 des ebenen Bügels 8 zu bilden, welcher Bügel seinerseits aus Stahldraht hergestellt und entsprechend einen Omega geformt ist.The same organ 7 is made of a rectangular lamella made of thin material, e.g. Spring material, obtained, which is bent at the top in 9 to form the bearing point for the two coaxial base lines 10, 11 of the flat bracket 8, which bracket itself is made of steel wire and is correspondingly shaped like an omega.

Das gegenüberliegende Ende der Lagerstellen ist als U umgebogen um damit eine verlängerte und, in dieser, eine verschiebbare Lagerstelle für die obere Traverse 13 eines entsprechenden, bewegbaren Bügels 8' zu bilden.The opposite end of the bearing points is bent over to form an elongated and, in this, a displaceable bearing point for the upper cross member 13 of a corresponding, movable bracket 8 '.

Durch die Verschiebebewegung "s" eines Bügels können die Leisten unter sich völlig zum Anliegen kommen wenn die Rolljalousie ganz nach unten gezogen ist. Dies erlaubt einen kompakten Vorhang zu bilden und eine völlige Verdunkelung des Raumes zu erhalten und, gleichzeitig, eine gute Isolierung zwischen der Strassenseite und dem Fenster zu verwirklichen. Wird der Vorhang teilweise angehoben, dann antfernen sich die Leisten voneinander und bilden den SpaltDue to the sliding movement "s" of a bracket, the strips can be completely under themselves Concerns come when the roller blind is pulled all the way down. This makes it possible to form a compact curtain and to completely obscure the room and, at the same time, to achieve good insulation between the street side and the window. If the curtain is partially raised, the strips move away from each other and form the gap

Das Oeffnen und Schliessen der Rolljalousie erfolgt durch Drehung, in der einen oder anderen Richtung, der bereits erwähnten Welle 5. Diese kann mit den hierzu herkömmlichen Mitteln angetrieben werden, und dies beispielsweise mit Hilfe einer Winde, eines Reimens, eines Motors oder eines anderen Mittels. Infolge der polygonförmigen Ausbildung der Welle 5 dient diese als Mitnehmer der Leisten, sei es in Schliessrichtung oder in Oeffnungsrichtung der Rolljalousie. Beim Schliessen bewegen sich die Leisten geführt und entlang den senkrechten Führungen 1' während sie sich beim Oeffnen im Raum A ansammeln.The roller blind is opened and closed by rotation, in one direction or the other, of the shaft 5 already mentioned. This can be driven using conventional means, for example with the aid of a winch, rhyme, motor or other means . As a result of the polygonal design of the shaft 5, this serves as a driver of the strips, be it in the closing direction or in the opening direction of the roller blind. When closing the strips move guided and along the vertical guides 1 'while they accumulate in room A when opened.

Die Lagerung der Leisten erfolgt indem sie sich im Raum oder Magazin A zickzackförmig überlagern, beispielsweise deren zwei oder drei usw. anliegend, ansammeln.The slats are stored by overlapping in space or magazine A, for example, two or three of them lying adjacent, accumulating.

Dieses wichtige Resultat wird durch eine Stopfen-Einheit 14, 15 (Figuren 7, 8, 9) erhalten, wobei die Stopfen mit Druck in die gegenüberliegenden Stirnseiten 2' eingeschoben sind.This important result is obtained by a plug unit 14, 15 (FIGS. 7, 8, 9), the plugs being pushed into the opposite end faces 2 'with pressure.

Die Tiefe der Einschiebung ist allerdings durch einen Anschlag 14' des Stopfens begrenzt, infolgedessen der Fortsatz oder Ansatz 16 ausserhalb der Stirnseite 2' der Leisten zu liegen kommt. Mit Vorteil wird der Fortsatz 16 einteilig mit einem ersten Stopfen 14 erhalten.However, the depth of the insertion is limited by a stop 14 'of the stopper, as a result of which the extension or extension 16 comes to lie outside the end face 2' of the strips. The extension 16 is advantageously obtained in one piece with a first stopper 14.

Die Stopfen greifen gegenseitig mittels diesem Fortsatz 16 ineinander, der aus elastischem, infolgedessen biegbarem Material hergestellt ist, und welcher Fortsatz in ein zugehöriges Loch 17 eines benachbarten zweiten Stopfens 15 eindringt.The plugs engage with one another by means of this extension 16, which is made of elastic, consequently bendable material, and which extension penetrates into an associated hole 17 of an adjacent second plug 15.

Die Gesamtheit von Stopfen und Fortsatz, wie eben beschrieben, versteift die Leisten unter sich zur Genüge, zwingt anderseits die Folge von zwei nachfolgenden Leisten sich mit Bezug auf die vorausgehende Folge zickzackförmig umzulegen, wobei das erwünschte Paket P gebildet wird. Die Biegsamkeit des Fortsatzes gewährleistet dem Vorhang der Rolljalousie sich zu biegen wenn er auf der Welle 5 einer Umlenkbewegung unterworfen wird während er die angrenzenden Leisten des Vorhanges genügend versteift wenn er sich, zickzackförmig zusammenlegend, um ein Paket P von Leisten zu bilden, in den Raum A hinunterbewegt.The entirety of the stopper and the extension, as just described, stiffens the strips enough below them, on the other hand forces the sequence of two subsequent strips to zigzag in relation to the preceding sequence, the desired package P being formed. The flexibility of the extension allows the curtain of the roller blind to bend when it is subjected to a deflection movement on shaft 5, while it stiffens the adjacent strips of the curtain sufficiently when it folds into the space in a zigzag shape to form a package P of strips A moved down.

Indem er sich im entsprechenden, im Stopfen 15 vorhandenen Loch 17 verschiebt, gewährleistet der Fortsatz 16 den benachbarten Leisten ein gegenseitiges Anliegen um auf diese Weise einen geschlossenen Vorhang zu bilden oder um sich zu distanzieren u m die vorerwähnten Schlitze "s", für den Durchgang von Licht und Luft zu erhalten. Diese Verschiebung wird allerdings durch den bereits erwähnten Bogen 8' des gelenkigen Verbindungsorganes 7 bestimmt.By moving in the corresponding hole 17 present in the plug 15, the extension 16 ensures that the adjacent strips rest against one another in order to form a closed curtain or to distance themselves from the aforementioned slots "s" for the passage of To get light and air. However, this displacement is determined by the already mentioned arc 8 'of the articulated connecting element 7.

Wenn die Stopfen 14, 15 aus Kunststoffmaterial hergestellt sind und wenn sie sich in den geradlinigen, senkrechten Führungen 1' fortbewegen gewährleisten sie ein gleichförmiges und geräuschloses Fortbewegen der Rolljalousie.If the plugs 14, 15 are made of plastic material and if they move in the straight, vertical guides 1 'they ensure a smooth and noiseless movement of the roller blind.

An den oberen Bereich der seitlichen Profile 1 und oberhalb der Welle 5 ist der bereits erwähnte Anschlag 18 befestigt, der etwa halbkreisförmig ausgebildet ist, und dessen Mittelpunkt mit der Achse der Welle übereinstimmt.The abovementioned stop 18, which is approximately semicircular in shape and whose center corresponds to the axis of the shaft, is fastened to the upper region of the lateral profiles 1 and above the shaft 5.

Wenn der Anschlag 18 im richtigen Abstand von der Achse der Welle 5 liegt, dann sichert er den Leisten den geführten Durchgang wenn die Welle betätigt wird, während er diesen Durchgang ausschliesst wenn die Welle im Stillstand ist.If the stop 18 is at the correct distance from the axis of the shaft 5, then it ensures the ledges the guided passage when the shaft is actuated, while excluding this passage when the shaft is at a standstill.

Die Massnahme, einen ganz bestimmten Abstand zwischen der Achsmitte der Welle und der Innenseite 18' des Anschlags 18 zu bilden, d.h. ein ganz bestimmter Abstand "Z" zwischen den Eckpunkten E der Welle und der vorerwähnten Innenseite 18', verhindert ein Oeffnen der Rolljalousie dann wenn sie abgesenkt ist und wenn die Welle 5 nicht betätigt wird.The measure of forming a very specific distance between the axis center of the shaft and the inside 18 'of the stop 18, i.e. a very specific distance "Z" between the corner points E of the shaft and the aforementioned inner side 18 'prevents the roller blind from opening when it is lowered and when the shaft 5 is not actuated.

Dadurch ergibt sich ein weiterer Vorteil der vorliegenden Erfindung, d.h. der der Sicherheit gegen ein missbräuchliches Oeffnen der Rolljalousie.This provides another advantage of the present invention, i.e. the security against an improper opening of the roller blind.

In der Praxis, wenn die Rolljalousie abgesenkt ist, bleibt somit diese automatisch verriegelt ohne das Anbringen von verwickelten und teueren Mechanismen, wie beispielsweise Winden oder der bei Rolljalousien bekannten Schlösser.In practice, when the roller blind is lowered, it remains locked automatically without the use of complicated and expensive mechanisms, such as winches or the locks known from roller blinds.

Die Verbindung der Welle 5 (Figuren 12, 13) mit der Mechanik für dessen Betätigung erfolgt durch die Zwischenanordnung, an einem Ende der Antriebswelle, einer Vorrichtung 19 welche einen einschnappbaren Eingriff besitzt. Die Vorrichtung 19 greift auf die Welle 5 ein und nimmt diese mit wenn ihre Drehung, die durch die Antriebsmechanik z.B. von Hand bestimmt ist, in Richtung der Oeffnung, d.h. in Richtung des Aufhebens der Rolljalousie erfolgt; wenn jedoch die Drehung der Welle 5 in Richtung des Absenkens oder Schliessens erfolgt, dann senkt sich die Rolljalousie aufgrund des Eigengewichts, und die Antriebsmechanik übernimmt dann, indem sie sich dreht, die Aufgabe der Steuerung der Absenkgeschwindigkeit. Auch in diesem Falle bleibt die Mechanik im Eingriff.The connection of the shaft 5 (FIGS. 12, 13) with the mechanism for its actuation takes place through the intermediate arrangement, at one end of the drive shaft, of a device 19 which has a snap-in engagement. The device 19 engages the shaft 5 and takes it with it when its rotation, which is caused by the drive mechanism e.g. is determined by hand in the direction of the opening, i.e. in the direction of lifting the roller blind; however, when the shaft 5 rotates in the direction of lowering or closing, the roller blind lowers due to its own weight, and the drive mechanism then, while rotating, takes over the task of controlling the lowering speed. In this case too, the mechanics remain in operation.

Nichtsdestoweniger, wenn die Rolljalousie völlig geschlossen ist oder im Begriff ist sich abzusenken, d.h. sich zu schliessen, und wenn sich der Absenkbewegung ein Widerstand dazwischenlegt, beispielsweise eine Person oder irgend ein Gegenstand und dabei die Antriebsmechanik in Bewegung ist, dann blockiert sich die Rolljalousie aufgrund der Vorrichtung 19 auch dann wenn die erwähnte Mechanik in Schliessrichtung weitergedreht wird, so dass Schaden an Personen, Sachen und an der Jalousie vermieden werden.Nonetheless, when the roller blind is completely closed or is about to lower, i.e. to close, and if the lowering movement intervenes, for example a person or some object and the drive mechanism is in motion, then the roller blind will block due to the device 19 even if the mentioned mechanism is turned further in the closing direction, so that Damage to people, things and the blind can be avoided.

In den Figuren 12, 13 ist die Vorrichtung 19 dargestellt. In ihr ist mit 22 eine Buchse angegeben, in deren Wand vier Längsnuten 23 ausgeführt sind in die Mitnehmer eingreifen, welche aus mit ebenen Parallelflächen gebildeten Körperen bestehen, und bei denen die nach aussen gerichtete Wand 24' geneigt ist.The device 19 is shown in FIGS. 12, 13. At 22 there is a socket in it indicated, in the wall of which four longitudinal grooves 23 are formed which engage the drivers, which consist of bodies formed with flat parallel surfaces, and in which the outwardly directed wall 24 'is inclined.

Mit 25 ist der Zapfen der Antriebsmechanik angegeben der, mit Bezug auf die Nuten, entsprechende Vertiefungen 26 zur Aufnahme der Mitnehmer 24 besitzt.With 25 the pin of the drive mechanism is indicated, which, with respect to the grooves, has corresponding recesses 26 for receiving the drivers 24.

Im äussersten Teil 27 des Zapfens 25 ist die bereits erwähnte Antriebsmechanik der Rolljalousie anbringbar.The drive mechanism of the roller blind, which has already been mentioned, can be attached in the outermost part 27 of the pin 25.

Wie aus den Figuren 12, 13 hervorgeht, dringen die Mitnehmer 24 in die entsprechenden Nuten 23 ein, bzw. sie ziehen sich infolge der Wirkung eines Hindernisses, das sich beim Herabsenken der Rolljalousie in den Weg stellt, aus diesen zurück, und dies aufgrund der geneigten äusseren Ebene 24' der Mitnehmer. Die Sicherheitsvorrichtung 19 dient als Endanschlag wenn die Rolljalousie völlig geschlossen ist.As can be seen from FIGS. 12, 13, the drivers 24 penetrate into the corresponding grooves 23, or they withdraw from them due to the action of an obstacle which is in the way when the roller blind is lowered, and this because of the inclined outer plane 24 'of the driver. The safety device 19 serves as an end stop when the roller blind is completely closed.

Auch ist ein Festhaltering 28 für die Mitnehmer vorgesehen, welcher den Nuten 23 zugehörige Vorsprünge 28' besitzt. Wird im Verlauf der Montage der Ring 28 in die Nuten 23 eingeführt, dann löst sich die Welle 5 von der Antriebsmechanik so dass die Montage der Wand erleichtert wird.A retaining ring 28 is also provided for the drivers, which has projections 28 ′ associated with the grooves 23. If the ring 28 is inserted into the grooves 23 in the course of the assembly, the shaft 5 is released from the drive mechanism so that the assembly of the wall is facilitated.

Ausserdem zickzackförmigen Umlegen, das den zwischen den entsprechenden Leisten montierten, elastischen Mittel zuzuschreiben ist, gewährleistet die Erfindung eine grosse Sicherheit gegen ein allfälliges, missbräuchliches Hochziehen des Vorhanges und bietet ausserdem eine Sicherheit für Personen und Sachen die entlang dem Schliessweg, d.h. beim Absenken des Vorhanges, sich vorfinden.In addition, zigzag folding, which is attributable to the elastic means mounted between the corresponding strips, the invention ensures a high level of security against any improper raising of the curtain and also provides security for people and things moving along the closing path, i.e. find yourself when lowering the curtain.
