Description

Die Erfindung bezieht sich auf einen Rollvorhang, insbesondere auf ein Rollo, nach dem Oberbegriff des Patentanspruches 1.The invention relates to a roller blind, in particular to a roller blind, according to the preamble of claim 1.

Die Funktion der einseitig an einem Ende der Wickelwelle angeordneten Antriebsmittel für den Rollvorhang erfordert eine drehfeste Zapfenlagerung dieses Endes der Wickelwelle. Dazu dient bei bekannten Ausführungen ein im Querschnitt mehrkantiger Wellenzapfen, welcher an einem inneren Lagerteil der Antriebsmittel ausgebildet ist und in einen an der Oberseite offenen Schlitz eines an der Wand oder dergleichen befestigbaren Halters drehfest eingehängt werden kann. Am anderen Ende der Wickelwelle ist bei bekannten Ausbildungen meistens ein einfacher Lagerdorn vorgesehen, der nach dem Einhängen des Wellenzapfens in den oben offenen Schlitz des Halters in eine Bohrung oder einen Schlitz mit einem runden Boden eines für dieses Ende der Wickelwelle vorgesehenen, somit anders ausgebildeten Halters eingesteckt wird. Die unterschiedlichen Wandhalter für beide Enden der Wickelwellenlagerung erlauben keine nachträgliche Änderung der Bedienungsseite ohne Wechsel des Wandhalters.The function of the drive means for the roller blind arranged on one side at one end of the winding shaft requires a rotationally fixed pin bearing of this end of the winding shaft. In the case of known designs, a shaft journal with a polygonal cross section is used for this purpose, which is formed on an inner bearing part of the drive means and can be non-rotatably suspended in a slot open at the top of a holder that can be attached to the wall or the like. At the other end of the winding shaft, a simple bearing pin is usually provided in known designs, which, after the shaft journal has been hooked into the slot of the holder open at the top, into a hole or a slot with a round bottom of a holder which is provided for this end of the winding shaft and is therefore of a different design is inserted. The Different wall brackets for both ends of the winding shaft bearing do not allow subsequent changes to the operating side without changing the wall bracket.

Aus der US-PS 4,372,432 ist eine für die Lagerung der Wickelwelle auf der Antriebsseite umgekehrte Ausbildung mit einem Tragzapfen am Halter an der Wand und einem Aufnahmeschlitz für diesen Tragzapfen in einem inneren Lagerteil der Antriebsmittel der Wickelwelle bekannt.From US-PS 4,372,432 a reverse design for mounting the winding shaft on the drive side is known with a support pin on the holder on the wall and a receiving slot for this support pin in an inner bearing part of the drive means of the winding shaft.

Die Aufgabe der Erfindung liegt darin, eine für beide Lagerungen der Wickelwelle möglichst gleiche Ausbildung zur variablen und sicheren Rollvorhangmontage auch an Schräg- und Deckenflächen mit möglichst kleinen Lichtspalten zu schaffen.The object of the invention is to provide a configuration for variable and secure rolling curtain assembly that is as identical as possible for both bearings of the winding shaft, even on inclined and ceiling surfaces with the smallest possible light gaps.

Diese Aufgabe löst die Erfindung durch die Ausbildung eines eingangs genannten Rollvorhangs mit Merkmalen nach dem Kennzeichen des Patentanspruches 1.This object is achieved by the invention by the formation of a roll curtain mentioned at the beginning with features according to the characterizing part of patent claim 1.

Hervorstechend ist die Verwendung gleichgestalteter Halter zur Lagerung beider Enden der Wickelwelle mit einem geringen Lichtspalt zwischen dem Vorhang und den Wandhaltern an beiden Enden der Wickelwelle. Der Rollvorhang kann in beide Wandhalter gleichzeitig von oben eingehängt werden, ist leicht handhabbar und ermöglicht eine sichere Montage in jeder beliebigen Position, insbesondere auch an schrägen Wand- oder Deckenflächen. Die Bedienungsseite kann nachträglich ohne Wechsel der Wandhalter geändert werden.What stands out is the use of identically designed holders for mounting both ends of the winding shaft with a small light gap between the curtain and the wall holders at both ends of the winding shaft. The roller blind can be hung in both wall brackets from above at the same time, is easy to handle and enables safe installation in any position, especially on sloping wall or ceiling surfaces. The operating page can be changed later without changing the wall bracket.

Bevorzugt wird eine Ausbildung, bei der der Wellenzapfen vormontiert in einer das Gehäuse bildenden, in eine stirnseitige Aufnahme der Wickelwelle drehfest eingesetzten Buchse gelagert ist. Dadurch wird die Vormontage der mit der Wickelwelle zu verbindenden Lagerelemente und eine einfache Steckverbindung dieser Lagerelemente mit der Wickelwelle ermöglicht. Das Sperrelement sollte nach dem Erfindungsgedanken gegenüber dem Wellenzapfen quer zum Aufnahmeschlitz unter elastischer Verformung gegen die dadurch bedingten Rückstellkräfte aus der Sperrlage heraus bis zur Freigabe des Tragzapfens in dem Aufnahmeschlitz beweglich sein. Bevorzugt wird ein Sperrelement mit einem stielartigen Befestigungszapfen, welches innerhalb des Wellenzapfens angeordnet und mit dem Befestigungszapfen in eine entsprechend profilierte Ausnehmung des Wellenzapfens eingesteckt ist und am Umfang des Wellenzapfens eine nach außen freiliegende Handhabe aufweist, so daß der Wellenzapfen unter elastischer Verformung um sein eingespanntes Ende zur Freigabe des Tragzapfens verschwenkt werden kann. Dies wird am besten durch ein im Querschnitt des Aufnahmeschlitzes L-förmiges Sperrelement erreicht, welches in der Sperrlage mit einem Schenkel den Tragzapfen im Aufnahmeschlitz an der offenen Schlitzseite hintergreift. Der für die Lagerung dieses Endes der Wickelwelle geeignete Wandhalter kann in übereinstimmender Ausbildung auch für die Lagerung des Endes der Wickelwelle auf der Antriebsseite Verwendung finden.An embodiment is preferred in which the shaft journal is mounted in a pre-assembled manner in a socket which forms the housing and is inserted in a rotationally fixed manner in an end receptacle of the winding shaft. This makes the pre-assembly of the bearing elements to be connected to the winding shaft and a simple plug connection of these bearing elements to the winding shaft enables. According to the concept of the invention, the locking element should be able to move from the locking position transversely to the receiving slot with elastic deformation against the restoring forces caused thereby until the support pin is released in the receiving slot. Preferred is a locking element with a handle-like fastening pin, which is arranged inside the shaft pin and is inserted with the fastening pin into a correspondingly profiled recess in the shaft pin and has an outwardly exposed handle on the circumference of the shaft pin, so that the shaft pin is deformed elastically around its clamped end can be pivoted to release the trunnion. This is best achieved by an L-shaped locking element in cross section of the receiving slot, which in the locked position engages with one leg behind the support pin in the receiving slot on the open slot side. The wall bracket suitable for the storage of this end of the winding shaft can also be used in a corresponding configuration for the storage of the end of the winding shaft on the drive side.

Die von der Erfindung berührte Lagerung der Wickelwelle 1 für einen Vorhang 2 aus einem aufwickelbaren Werkstoff setzt sich aus einem buchsenartigen Gehäuse 3, einem darin frei drehbar gelagerten Wellenzapfen 4 und einem Sperrelement 5 zusammen. In dem Wellenzapfen 4 ist ein einseitig offener Schlitz 6 ausgebildet, mit dem dieser Wellenzapfen 4 auf einen Tragzapfen 7 aufgehängt werden kann, welcher an einem an einer Wand, Decke oder dergleichen befestigbaren Halter 8 ausgebildet ist. Der Aufnahmeschlitz 6 und der Tragzapfen 7 weisen das gleiche Querschnittsprofil auf. Der Wellenzapfen 4 ist bei dem Ausführungsbeispiel in einer das Gehäuse 3 bildenden Buchse frei drehbar gelagert und daran gleichzeitig gegen axiale Verschiebung relativ zueinander gesichert. Das Gehäuse 3 ist drehfest in eine stirnseitige Aufnahme der Wickelwelle 1 einsetzbar, so daß die Drehbewegung beim Öffnen und Schließen des Behangs zwischen dem Gehäuse 3 und der Lagerfläche am Wellenzapfen 4 erfolgt. Innerhalb des Wellenzapfens 4 ist das Sperrelement 5 ausreichend beweglich und mit einem stielartigen Befestigungsende 9 in eine Haltetaschenausbildung des Wellenzapfens 4 spielfrei eingesetzt, so daß das Sperrelement unter elastischer Materialverformung quer zum Aufnahmeschlitz 6 beweglich ist. Im Bereich dieses Aufnahmeschlitzes ist das Sperrelement 5 mit Blick auf die Achsrichtung der Wickelwelle 1 L-förmig ausgebildet und hintergreift mit einem Schenkel 10 einen in den Aufnahmeschlitz 6 eingeführten Tragzapfen 7 des Halters 8. Am Umfang des Wellenzapfens 4 weist das Sperrelement 5 eine Handhabe 11 auf, so daß das Sperrelement 5 unter Benutzung dieser Handhabe 11 radial nach innen quer zum Schlitz 6 unter elastischer Verformung des Befestigungsendes 9 und dem gleichzeitigen Aufbau von Rückstellkräften so weit zur Seite beweglich ist, daß der Schenkel 10 aus dem Bereich des Schlitzes 6 zurückgedrückt werden kann, um den Tragzapfen 7 freizugeben. Zum Einführen des Tragzapfens 7 in den Schlitz 6 ist das vordere Ende des Schenkels 10 abgeschrägt, so daß bei einer Bewegung des Tragzapfens 7 gegen diese Schrägfläche selbsttätig ein Zurückweichen des Sperrelementes 5 und eine selbsttätige Verriegelung des Tragzapfens 7 in dem Aufnahmeschlitz 6 erfolgt. Zum Abheben des Lagers vom Tragzapfen 7 des Halters 8 wird das Sperrelement durch radialen Druck auf die Handhabe 11 zur Seite gedrückt, so daß der Schenkel 10 des Sperrelements 5 aus dem Aufnahmeschlitz 6 zurückgedrückt wird. BEZUGSZEICHENLISTE: 1 Wickelwelle 7 Tragzapfen 2 Vorhang 8 Halter 3 Gehäuse 9 Befestigungsende 4 Wellenzapfen 10 Schenkel 5 Sperrelement 11 Handhabe 6 Aufnahmeschlitz The bearing of the winding shaft 1 for a curtain 2 made of a material that can be wound up, which is affected by the invention, is composed of a bush-like housing 3, a shaft journal 4 freely rotatably mounted therein and a locking element 5. In the shaft journal 4 there is a slot 6 which is open on one side and by means of which this shaft journal 4 can be suspended on a support journal 7 which is constructed on a holder 8 which can be fastened to a wall, ceiling or the like. The receiving slot 6 and the support pin 7 have the same cross-sectional profile. In the exemplary embodiment, the shaft journal 4 is freely rotatably mounted in a socket forming the housing 3 and at the same time is secured there against axial displacement relative to one another. The housing 3 can be inserted in a rotationally fixed manner in an end receptacle of the winding shaft 1, so that the rotational movement occurs when the curtain is opened and closed between the housing 3 and the bearing surface on the shaft journal 4. Within the shaft pin 4, the locking element 5 is sufficiently movable and with a handle-like fastening end 9 inserted into a holding pocket formation of the shaft pin 4 without play, so that the locking element can be moved transversely to the receiving slot 6 with elastic material deformation. In the area of this receiving slot, the locking element 5 is L-shaped with a view of the axial direction of the winding shaft 1 and engages with a leg 10 behind a support pin 7 of the holder 8 inserted into the receiving slot 6. On the circumference of the shaft pin 4, the locking element 5 has a handle 11 on, so that the locking element 5 using this handle 11 radially inward across the slot 6 with elastic deformation of the fastening end 9 and the simultaneous build-up of restoring forces is so far to the side that the leg 10 can be pushed back from the area of the slot 6 to release the support pin 7. For insertion of the trunnion 7 into the slot 6, the front end of the leg 10 is chamfered, so that when the trunnion 7 moves against this inclined surface, the locking element 5 automatically retracts and the trunnion 7 is automatically locked in the receiving slot 6. To lift the bearing from the trunnion 7 of the holder 8, the locking element is pressed to the side by radial pressure on the handle 11, so that the leg 10 of the locking element 5 is pushed back out of the receiving slot 6.
