Abstract

A roller blind for closing openings in buildings, such as windows, doors, or the like, which blind is formed from a plurality of laminated strips which are attached one to the other and whose ends are guided in guide rails, and has an insertable bolt for locking the roller blind and which is provided in the lowermost laminated strip. This lowermost strip is formed as an end bar housing said bolt which can penetrate into an opening in one of the guide rails in the closed (locked) position under the action of a spring. For unlocking purposes, a cord which is secured to the bolt, is guided upwards through endpieces of the laminated strips and secured so that, upon winding the laminated strips around the winding shaft, the bolt is withdrawn from the opening in the guide rail against the action of the spring.

Description

Die Erfindung betrifft einen Rolladen mit einer Vielzahl aneinander gehängter, als Hohlkörper ausgebildeter Lamellen, die an ihren seitlichen Enden in zwei seitlichen Führungsschienen geführt sind, und mit einer Verriegelungseinrichtung, wobei die als unterste Lamelle wirkende Abschlußleiste einen in eine Öffnung einer Führungsleiste einschiebbaren, abgefederten Riegel enthält und die Lamellen in ihren seitlichen Enden jeweils mittels eines die Verschiebung des Riegels in die Öffnungsstellung bewirkenden, innerhalb der Führungsschiene verlaufenden Seiles geführt sind.The invention relates to a roller shutter with a plurality of mutually attached, formed as a hollow body slats, which are guided at their lateral ends in two lateral guide rails, and with a locking device, the bottom strip acting as the bottom slat a spring bar that can be inserted into an opening of a guide bar contains and the slats are guided in their lateral ends by means of a rope which causes the displacement of the bolt into the open position and extends within the guide rail.

Ein derartiger Rolladen ist aus der DE-A-1 809 071 bekannt. Zur Führung der seitlichen Seile sind jedoch in nachteiliger Weise in die Enden von Lamellen Schlitze eingearbeitet, die festigkeitsmäßig derartige Lamellen schwächen. Um ein Herausziehen der Seile aus den Schlitzen zu vermeiden, sind in Bohrungen eingesteckte Stifte am Ende der Lamelle notwendig, die zusätzlich arbeitsaufwendig in der Herstellung und/oder Montage des Rolladens sind.Such a roller shutter is known from DE-A-1 809 071. To guide the side ropes, however, slots are disadvantageously incorporated into the ends of slats, which weaken the strength of such slats. In order to prevent the ropes from being pulled out of the slots, pins inserted into bores at the end of the slat are necessary, which are also labor-intensive in the manufacture and / or assembly of the roller shutter.

Aufgabe der Erfindung ist es, unter Beseitigung der vorgenannten Nachteile eine verbesserte, einfach zu montierende und die Enden der Lamellen vestärkende Seilführung zu schaffen.The object of the invention is to provide an improved, easy to assemble and reinforcing the ends of the slats reinforcing rope guide while eliminating the aforementioned disadvantages.

Gemäß der Erfindung wird diese Aufgabe bei einem Rolladen der vorgenannten Gattung dadurch gelöst, daß mehrere Lamellen jeweils an ihrem Ende mit darin eingesteckten, diese verschließenden und in der jeweiligen Führungsschiene gelagerten Abschlußstücken ausgestattet sind, durch deren senkrechte Bohrung das innerhalb der Führungsschiene verlaufende Seil hindurchgeführt ist.According to the invention, this object is achieved in a roller shutter of the aforementioned type in that a plurality of slats are each equipped at their end with plugged therein, closing them and mounted in the respective guide rail, through the vertical bore of which the cable running inside the guide rail is passed .

Der erfindungsgemäße Rolladen besteht aus mehreren aneinander angehängten und gleichartig ausgeführten Lamellen 10, die an beiden Seiten der Tür- oder Fensteröffnung mit ihren Enden in Führungsschienen 11 geführt werden. Der Rolladen läßt sich auf eine in einem Rolladenkasten 12 angeordnete Wickelwelle aufrollen, die beispielsweise mit Hilfe eines Gurtes 13 betätigt wird. Die Lamellen 10 sind als Hohlkörper ausgebildet und können mit einem Kunststoff ausgeschäumt sein. Die unterste Lamelle ist als Abschlußleiste 14 mit einem Hohlraum ausgeführt, von dem ein Kanal 15 abgetrennt ist.The roller shutter according to the invention consists of a plurality of mutually attached and identically designed slats 10, which are guided with their ends in guide rails 11 on both sides of the door or window opening. The roller shutter can be rolled up on a winding shaft arranged in a roller shutter box 12, which is actuated for example with the aid of a belt 13. The slats 10 are designed as hollow bodies and can be foamed with a plastic. The lowest lamella is designed as an end strip 14 with a cavity from which a channel 15 is separated.

Gemäß Fig. 2 und 3 der Zeichnung ist innerhalb des Hohlraumes der Abschlußleiste 14 am unteren Ende ein in waagerechter Richtung verschiebbarer Riegel 16 angeordnet, der sich in der Öffnungsstellung vollständig innerhalb der Abschlußleiste 14 befindet und in der Schließstellung mit einem Ende in eine Öffnung 17 der benachbarten Führungsschiene 11 hineinragt. Würde man versuchen, den Rolladen nun anzuheben, so würde der Riegel 16 an der Öffnung 17 festgehalten, wodurch das Anheben des Rolladens behindert würde.2 and 3 of the drawing, a horizontally displaceable bolt 16 is arranged inside the cavity of the end bar 14 at the lower end, which is located completely inside the end bar 14 in the open position and in the closed position with one end in an opening 17 of the protrudes adjacent guide rail 11. If one tried to lift the roller shutter now, the latch 16 would be held at the opening 17, which would prevent the roller shutter from being lifted.

Für die Verschiebung des Riegels 16 in die Öffnung 17 hinein sorgt eine Feder 18, die als zylindrische Schrauben-Zugfeder ausgebildet ist. Sie ist mit einem Ende an einem Ausleger 19 gehalten, der an dem Riegel 16 befestigt ist. Das andere Ende der Feder 18 wird von einem Ausleger 20 gehalten, der an einem Steckteil 21 befestigt ist, welches fest in den Kanal 15 der Abschlußleiste 14 eingesteckt ist. Für die Bewegung des Riegels 16 entgegen der Wirkung der Feder 18 aus der Öffnung 17 heraus sorgt ein Seil 22, welches innerhalb der Führungsschiene 11 angeordnet ist. Das untere Ende des Seiles 22 ist an einem Schwenkhebel 23 befestigt, der über ein Gelenk 24 an dem Ausleger 20 schwenkbar gelagert ist. Das von dem Seil 22 entfernte Ende des Schwenkhebels 23 ist an einem weiteren Schwenkhebel 25 angelenkt, der wiederum an dem Ausleger 19 des Riegels 16 angelenkt ist.A spring 18, which is designed as a cylindrical helical tension spring, provides for the displacement of the bolt 16 into the opening 17. It is held at one end on a bracket 19 which is attached to the bolt 16. The other end of the spring 18 is held by a bracket 20 which is fastened to a plug-in part 21 which is firmly inserted into the channel 15 of the end strip 14. A cable 22, which is arranged within the guide rail 11, provides for the movement of the bolt 16 against the action of the spring 18 out of the opening 17. The lower end of the rope 22 is fastened to a pivot lever 23 which is pivotably mounted on the boom 20 via a joint 24. The end of the pivot lever 23 remote from the cable 22 is articulated on a further pivot lever 25, which in turn is articulated on the arm 19 of the bolt 16.

Das Seil 22 ist innerhalb der Führungsschiene 11 durch Bohrungen 26 mehrerer Abschlußstükke 27 hindurchgeführt, die in die Lamellen 10 seitlich eingesteckt sind und diese verschließen. An seinem oberen Ende ist das Seil 22 an der obersten Lamelle 10 befestigt und wird mit dieser angehoben bzw. abgesenkt. Beim Hochziehen des Rolladens zieht das Seil 22 an seinem unteren Ende den Schwenkhebel 23 mit hoch, so daß sich dieser um sein Gelenk 24 verschwenkt und über den Schwenkhebel 25 den Riegel 16 gegen die Wirkung der Feder 18 vollständig in den Hohlraum der Abschlußleiste 14 hineinverschiebt. Dabei verläßt der Riegel 16 die Öffnung 17 der Führungsschiene 11, so daß der Rolladen entriegelt ist und auch die Abschlußleiste 14 hochgezogen werden kann.The rope 22 is guided within the guide rail 11 through bores 26 of a plurality of end pieces 27, which are inserted laterally into the slats 10 and close them. At its upper end, the rope 22 is fastened to the uppermost slat 10 and is raised or lowered with it. When the roller shutter is pulled up, the cable 22 pulls the pivot lever 23 up at its lower end, so that it pivots about its joint 24 and, via the pivot lever 25, completely moves the bolt 16 against the action of the spring 18 into the cavity of the end strip 14. The bolt 16 leaves the opening 17 of the guide rail 11 so that the roller shutter is unlocked and the end bar 14 can be pulled up.

Das Seil 22 ist in seiner Länge so eingestellt, daß nach dem Herablassen des Rolladens der Schwenkhebel 23 infolge der Wirkung der Feder 18 die in Fig.2 gezeichnete Lage einnehmen kann, so daß der Riegel 16 von der Feder 18 in die Öffnung 17 hineinbewegt und die Verriegelung des Rolladens durchgeführt wird.The rope 22 is adjusted in length so that after lowering the roller shutter the pivot lever 23 can assume the position shown in Fig.2 due to the action of the spring 18, so that the bolt 16 moves by the spring 18 into the opening 17 and the shutter is locked.

Gemäß Fig. 4 und 5 der Zeichnung ist der Riegel 28 am oberen Ende eines Schwenkhebels 29 befestigt, beispielsweise mit diesem einstückig ausgeführt. Der Schwenkhebel 29 ist in einem in den Hohlraum der Abschlußleiste 14 fest eingesteckten Steckteil 30 über ein Gelenk 31 gelagert. Die das Verriegeln bewirkende Feder 32 ist als zylindrische Schrauben-Druckfeder ausgeführt, die sich mit einem Ende innerhalb einer Bohrung 33 des Steckteils 30 und mit dem anderen Ende an einem Zapfen 34 des Schwenkhebels 29 abstützt. Das Seil 22 greift mit seinem unteren Ende unmittelbar am Riegel 28 an, es ist duch eine Bohrung 35 des Riegels 28 hindurchgeführt und dort befestigt. In diesem Ausführungsbeispiel bewegt sich der Riegel 28 nicht exakt geradlinig, sondern längs eines Kreises mit dem Gelenk 31 als Mittelpunkt. Nach dem Aufsetzen der Abschlußleiste 14 bewegt sich beim weiteren Herablassen des Rolladens das Seil 22 abwärts, so daß am Riegel 28 keine Zugkraft mehr nach oben wirkt. Mit dem Schwenkhebel 29 kann der Riegel 28 dann von der Feder 32 in die Öffnung 36 der Führungsschiene 11 hineingedrückt und die Verriegelung auf diese Weise durchgeführt werden. Beim Hochziehen des Rolladens bewirkt als erstes das Seil 22 eine Verschwenkung des Riegels 28 aus der Öffnung 36 heraus und in den Hohlraum der Abschlußleiste 14 hinein gegen die Wirkung der Feder 32. Dadurch wird die Verriegelung freigegeben und auch die Abschlußleiste 14 kann mit hochgezogen werden.4 and 5 of the drawing, the bolt 28 is at the upper end of a pivot lever 29 attached, for example, in one piece with this. The pivot lever 29 is mounted in a plug-in part 30 which is firmly inserted into the cavity of the end strip 14 via a joint 31. The locking effect spring 32 is designed as a cylindrical helical compression spring which is supported at one end within a bore 33 of the plug part 30 and at the other end on a pin 34 of the pivot lever 29. The cable 22 engages with its lower end directly on the bolt 28, it is passed through a hole 35 in the bolt 28 and fastened there. In this exemplary embodiment, the bolt 28 does not move exactly in a straight line, but rather along a circle with the joint 31 as the center. After the end strip 14 has been put in place, the cable 22 moves downward when the roller shutter is lowered further, so that no more tensile force acts upward on the bolt 28. With the pivot lever 29, the bolt 28 can then be pressed by the spring 32 into the opening 36 of the guide rail 11 and the locking can be carried out in this way. When the roller shutter is pulled up, the rope 22 first causes the bolt 28 to pivot out of the opening 36 and into the cavity of the end strip 14 against the action of the spring 32. This releases the lock and the end strip 14 can also be pulled up.

Gemäß Fig. 6 und 7 wird der Riegel 37 von seiner Feder 38 beaufschlagt, die als Blattfeder ausgebildet und an einem Lagerblech 39 mit einem Ende befestigt ist. Das Seil 22 greift an einer an dem Riegel 37 befestigten Öse 40 an. Um auch hier entgegen der Wirkung der Feder 38 den Riegel 37 verschieben zu können, muß in diesem Ausführungsbeispiel das Seil 22 über zwei an dem Lagerblech 39 gelagerte Umlenkrollen 41 umgelenkt werden. Für die Führung des Riegels 37 weist das Lagerblech 39 einen abgekröpften Schenkel 43 und Nocken 42 auf.6 and 7, the bolt 37 is acted upon by its spring 38, which is designed as a leaf spring and is attached to a bearing plate 39 with one end. The rope 22 engages an eyelet 40 attached to the bolt 37. In order to be able to move the bolt 37 against the action of the spring 38, in this exemplary embodiment the cable 22 must be deflected via two deflection rollers 41 mounted on the bearing plate 39. For guiding the bolt 37, the bearing plate 39 has a bent leg 43 and cam 42.

Anstelle der Blattfeder 38 kann auch, wie in Fig. 2 dargestellt, eine Zugfeder 18 angeordnet werden, die mit einem Ende am Lagerblech 39 und mit dem anderen Ende am Riegel 37 befestigt ist. Es kann auch eine Druckfeder 32 gemäß Fig. 4 verwendet werden, wobei das Lagerblech 39 einen in Verriegelungsrichtung abgebogenen Anschlag am Gegenlager aufweist und im Riegel 37 eine Bohrung zur Aufnahme der Druckfeder vorzusehen ist.Instead of the leaf spring 38, a tension spring 18 can also be arranged, as shown in FIG. 2, which is attached at one end to the bearing plate 39 and at the other end to the bolt 37. A compression spring 32 according to FIG. 4 can also be used, the bearing plate 39 having a stop on the counter bearing bent in the locking direction and a bore for receiving the compression spring being provided in the bolt 37.
