Description

Die Erfindung bezieht sich auf ein Kassettenrollo mit einem Beschwerungsprofil am unteren Ende eines Behanges und einem Rolloantrieb.The invention relates to a cassette roller blind a weighting profile at the lower end of a curtain and a roller blind drive.

Ein solches Kassettenrollo ist aus DE 42 39 507 A1 bekannt. Diese Druckschrift beschreibt abwechselnd mit einer Verzahnung in Axialnuten am Außenumfang eines ortsfest verankerten Zapfens und in Axialnuten am Innenumfang eines rohrförmigen, mit dem Antriebsglied in Drehrichtung kuppelbaren Gehäuses befestigte Reibscheiben, die durch Axialkräfte unter axialer Verschiebung gegeneinander preßbar sind. Dazu ist eine von zwei auf dem Zapfen axial verschiebbaren Endscheiben in Drehrichtung innerhalb eines vorbestimmten Drehwinkels durch eine Drehmomentfeder belastet und die andere Endscheibe lediglich axial verschiebbar, aber drehfest mit dem Antriebsglied gekuppelt. Durch die relativ schwache Drehmomentfeder werden relativ große Kuplungs- bzw. Bremskräfte initiiert, so daß ein solcher Antrieb besonders leichtgängig und vor allem für große Behanggewichte geeignet ist. Bei solchen und vergleichbaren Kassettenrollos stellt sich das Problem, daß das am unteren Rand des Behanges angeordnete Beschwerungsprofil beim Hochziehen des Behanges zwar gegen das Kassettenprofil der die Wickelwelle und das darauf aufgewickelte Rollo aufnehmenden Kassette gezogen werden kann, aber nach dem Loslassen der Antriebskräfte ein kurzes Stück zurückfällt, so daß ein schmaler Streifen des Behanges zwischen dem Beschwerungsprofil und dem Kassettenprofil erneut sichtbar wird. Dies ist häufig unerwünscht, weil es das Aussehen des hochgezogenen Kassettenrollos beeinträchtigt.Such a cassette roller blind is from DE 42 39 507 A1 known. This document describes alternately with a toothing in axial grooves on the outer circumference of a stationary anchored pin and in axial grooves on Inner circumference of a tubular, with the drive member in Attached direction of rotation of the detachable housing Friction disks caused by axial forces under axial Shift can be pressed against each other. There is one of two end disks axially displaceable on the pin in the direction of rotation within a predetermined angle of rotation loaded by one torque spring and the other End plate only axially displaceable, but non-rotatable coupled with the drive link. By the relative weak torque spring become relatively large coupling or Braking forces initiated, so that such a drive particularly smooth and especially for large ones Curtain weights are suitable. With such and comparable cassette roller blinds the problem arises that the arranged at the bottom of the curtain Weight profile when pulling up the curtain against the cassette profile of the winding shaft and that the cassette holding the roller blind wound on it can be, but after releasing the driving forces falls back a short distance so that a narrower Strip of curtain between the weight profile and the cassette profile is visible again. This is common undesirable because it is the look of the hoisted Cassette blinds impaired.

Es ist daher Aufgabe der Erfindung, die Antriebsmittel des Rollos derart zu gestalten, daß das Beschwerungsprofil nach dem Hochziehen des Rollos nicht mehr zurücksackt.It is therefore an object of the invention, the drive means to design the roller blind in such a way that Weight profile not after the blind is raised sags more.

Die Erfindung löst diese Aufgabe durch ein Kassettenrollo mit den Merkmalen des Patentanspruches 1.The invention solves this problem with a cassette roller blind with the features of claim 1.

Durch diese Ausbildung wird erreicht, daß das Antriebsglied am Ende der Aufwickelbewegung des Behanges, wenn das Beschwerungsprofil bereits gegen das Kassettenprofil zur Anlage gekommen ist, noch um den vorgegebenen Winkel gegen die Federwirkung weitergedreht werden kann. Beim Loslassen der manuell oder motorisch ausgeübten Antriebskraft wird das Beschwerungsprofil durch die Federkraft gegen das Kassettenprofil gehalten, so daß die Elemente der nunmehr wirksamen Bremskupplung innerhalb des vorgespannten Drehwinkels zum gegenseitigen Eingriff beweglich sind. Die Feder wirkt dem Behanggewicht entgegen und kann relativ schwach ausgebildet sein, so daß das Behanggewicht die an der Wickelwelle befestigten Kupplungselemente in die eine Anschlaglage zieht. Erst gegen Ende der Aufwickelbewegung des Behanges wird die Feder wirksam, so daß sie die Kupplungselemente in die andere Anschlaglage des vorgegebenen Drehwinkels zieht, so daß die Kupplungselemente noch innerhalb des vorgegebenen Winkels relativ zueinander verdrehbar sind, wenn das Beschwerungsprofil bereits am Kassettenprofil anliegt.This training ensures that Drive element at the end of the winding movement of the curtain, if the complaint profile is already against the Cassette profile has come to the plant, yet predetermined angle rotated against the spring action can be. When you release the manual or motor Exercised driving force becomes the weighting profile held against the cassette profile by the spring force, so that the elements of the now effective brake clutch within the prestressed angle of rotation to the other Are movable. The feather works Curtain weight counter and can be relatively weak be designed so that the hanging weight on the Winding shaft attached coupling elements in one Stop position pulls. Only towards the end of the winding movement of the curtain, the spring is effective so that it Coupling elements in the other stop position of the predetermined angle of rotation so that the Coupling elements still within the specified angle are rotatable relative to each other if that The weighting profile is already on the cassette profile.

Vorteilhafte Ausbildungsmerkmale zur weiteren Ausgestaltung der Erfindung enthalten die Ansprüche 2 bis 5.Advantageous training features for further development the invention contain claims 2 to 5.

Das Ausführungsbeispiel zeigt ein Kassettenrollo, bei dem ein Behang 1, an dessen unterer Kante ein Beschwerungsprofil 2 befestigt ist, innerhalb eines Kassettenprofiles 3 auf eine darin gelagerte Wickelwelle 4 aufwickelbar ist. Dazu dienen meistens einseitig an einem Ende innerhalb der Wickelwelle 4 angeordnete Antriebsglieder, die durch eine seitlich neben dem Behang 1 aus dem Kassettenprofil 3 herausgeführte Antriebskette 5 oder auch motorische Antriebsmittel betätigt werden. Kassettenrollos nach der Erfindung unterscheiden sich von Springrollos dadurch, daß das Aufwickeln des Behanges 1 auf die Wickelwelle 4 durch Antriebskräfte erfolgt und nicht durch eine beim Herunterziehen des Behanges gespannte Torsionsfeder. Zwischen dem durch die Antriebskette 5 drehbaren Antriebsglied 6 und der Wickelwelle 4 sind einerseits Kupplungsglieder vorgesehen, die zum Hochziehen des Behanges 1 eine drehfeste Verbindung zwischen dem Antriebsglied 6 und der Wickelwelle 4 ermöglichen. Andererseits sind zwischen der Wickelwelle 4 und einem ortsfest verankerten Zapfen 7 Bremsglieder vorgesehen, durch die die Wickelwelle 4 festgesetzt wird, sobald keine Antriebskräfte in Aufwickelrichtung auf das Antriebsglied 6 wirksam sind. Bei dem Ausführungsbeispiel ist das Antriebsglied 6 konzentrisch innerhalb eines rohrförmigen Gehäuses 8 durch Anschläge drehwinkelbegrenzt beweglich gelagert. Die Drehwinkelbegrenzung erfolgt durch erste komplementäre, Kupplungselemente, die als Anschläge 9 am Innenmantel der rohrförmigen Wickelwelle 4 und Anschläge 10 am Außenmantel des Gehäuses 8 gebildet sind. Auf dem Zapfen 7 sind als Bremsscheiben funktionierende zweite komplementäre Kupplungselemente 11 und 12 axial verschieblich angeordnet, die abwechselnd drehfest mit dem Zapfen 7 und drehfest mit dem rohrförmigen Gehäuse 8 verbunden sind. Das Paket aus den Bremsscheiben 11 und 12 stützt sich an einem Ende gegen ein fest auf dem Zapfen 7 angeordnetes Widerlager 13 ab. Die Endscheibe 14 am gegenüberliegenden Ende weist eine Axialkurve auf, die mit einer Axialkurve an einem Zwischenglied 15 derart zusammenwirkt, daß das Paket aus den Bremsscheiben 11 und 12 bei einer Drehbewegung des Antriebsgliedes 6 in Aufwickelrichtung des Behanges 1 gelöst und am Beginn einer Drehbewegung in Gegenrichtung durch die Axialkurven zusammengepreßt wird. Dritte komplementäre Kupplungselemente sind durch ein mit dem Gehäuse 8 drehfest verbundenes Kupplungselement 16 und durch eine Hülse 18 geformt. Kupplungselement 16 ist in einem Drehwinkel gegen eine Torsionsfeder 17 beweglich mit der Hülse 18 verbunden, die axialverschieblich aber drehfest mit der Wickelwelle 4 verbunden ist. Zapfenartige Radialvorsprünge der Hülse 18 greifen in Profilnuten der Anschläge 9 am Innenumfang der rohrförmigen Wickelwelle 4 ein. Das eine Ende der Torsionsfeder 17 ist an dem Kupplungselement 16 und das andere Ende der Torsionsfeder 17 an der Hülse 18 festgelegt. Die Torsionsfeder 17 wird bei einer Drehbewegung des Antriebsgliedes 6 in Aufwickelrichtung des Behanges 1 gespannt. Das Behanggewicht überwindet die maximale Federspannung, so daß das rohrförmige Gehäuse 8 und die rohrförmige Wickelwelle 4 in eine durch die Anschläge 9 und 10 definierte Anschlaglage gelangen. Am oberen Ende der Aufrollbewegung des Behanges 1 wird die Torsionsfeder 17 in der Weise wirksam, daß sie die Wickelwelle 4 voreilend verdreht, so daß das Antriebsglied 6 noch weitergedreht werden kann, wenn die Beschwerungsleiste bereits die in Figur 2 dargestellte Position eingenommen hat und gegen das Kassettenprofil 3 anliegt, wodurch die weitere Drehbewegung der Wickelwelle 4 blockiert wird. Zur Vermeidung einer Überdehnung der Torsionsfeder 17 wird die Möglichkeit der Weiterdrehung durch die Anschläge 9 und 10 zwischen der Wickelwelle 4 und dem Gehäuse 8 begrenzt. Damit nun die Bremswirkung des Paketes aus den Bremsscheiben 11 und 12 wirksam werden kann, ist eine geringfügige Rückdrehung des Antriebsgliedes 6 erforderlich. Diese erfolgt nunmehr innerhalb der Federspannung, so daß das Beschwerungsprofil 2 nicht in die in Figur 3 dargestellte, unerwünschte Lage absacken kann. Die Größe des durch die Anschläge 9 und 10 begrenzten Winkels sollte größer sein, als der für den Eingriff der Bremselemente erforderliche Drehwinkel, so daß das Beschwerungsprofil 2 in der in Figur 2 dargestellten Stellung mit geringer Federspannung gegen das Kassettenprofil 3 gehalten wird. Bei dem Ausführungsbeispiel ist auch das mit dem rohrförmigen Gehäuse 8 drehfest verbundene Kupplungselement 16 als Hülse ausgebildet, auf der die Hülse 18 konzentrisch angeordnet ist. The embodiment shows a cassette roller blind in which a curtain 1, on its lower edge Weight profile 2 is attached within a Cassette profile 3 on a winding shaft 4 mounted therein can be wound up. Mostly serve one-sided on one End arranged within the winding shaft 4 Drive elements, which are located on the side next to the curtain 1 Drive chain 5 guided out of the cassette profile 3 or motorized drive means are operated. Cassette roller blinds according to the invention differ from Spring blinds in that the winding of the curtain 1 the winding shaft 4 is done by driving forces and not by a tensioned when pulling down the curtain Torsion spring. Between the drive chain 5 rotatable drive member 6 and the winding shaft 4 are on the one hand coupling links provided for pulling up of the curtain 1 a non-rotatable connection between the Enable drive member 6 and the winding shaft 4. On the other hand, between the winding shaft 4 and one stationary anchored pin 7 brake members provided, through which the winding shaft 4 is fixed as soon as none Driving forces in the winding direction on the drive member 6 are effective. In the embodiment, this is Drive member 6 concentric within a tubular Housing 8 can be moved by stops limited in rotation stored. The rotation angle is limited by the first complementary, coupling elements that act as stops 9 on the inner surface of the tubular winding shaft 4 and Stops 10 are formed on the outer casing of the housing 8. On the cone 7 are second complementary ones functioning as brake disks Coupling elements 11 and 12 axially displaceable arranged, which alternately rotatably with the pin 7 and are rotatably connected to the tubular housing 8. The Package from the brake discs 11 and 12 is supported on one End against a fixed on the pin 7 Abutment 13 from. The end plate 14 on the opposite The end has an axial curve, the one with an axial curve an intermediate member 15 cooperates so that the package from the brake discs 11 and 12 when the Drive member 6 in the winding direction of the curtain 1 solved and at the beginning of a rotational movement in the opposite direction is pressed together by the axial curves. Third complementary Coupling elements are through one with the Housing 8 rotatably connected coupling element 16 and by a Sleeve 18 shaped. Coupling element 16 is in with an angle of rotation against a torsion spring 17 the sleeve 18 connected, but axially displaceable is rotatably connected to the winding shaft 4. Cone-like Radial projections of the sleeve 18 engage in profile grooves Stops 9 on the inner circumference of the tubular winding shaft 4 on. One end of the torsion spring 17 is on the Coupling element 16 and the other end of the torsion spring 17 fixed to the sleeve 18. The torsion spring 17 will when the drive member 6 rotates Winding direction of the curtain 1 tensioned. The Curtain weight overcomes the maximum spring tension, so that the tubular housing 8 and the tubular winding shaft 4 in one defined by the stops 9 and 10 Stop position. At the top of the reeling movement of the curtain 1, the torsion spring 17 in the way effective that it rotates the winding shaft 4 leading, so that the drive member 6 can be rotated further, if the weighting bar already corresponds to that in FIG has shown position and against that Cassette profile 3 abuts, causing the further rotation the winding shaft 4 is blocked. To avoid a Overextension of the torsion spring 17 becomes the possibility of Continued rotation through the stops 9 and 10 between the Winding shaft 4 and the housing 8 limited. So now the Braking effect of the package from the brake discs 11 and 12 can take effect is a slight turn back of the Drive member 6 required. This is now done within the spring tension so that the weight profile 2 not in the undesirable position shown in Figure 3 can sag. The size of the stops 9 and 10 limited angle should be larger than that for the Engagement of the braking elements required angle of rotation, so that the weighting profile 2 shown in Figure 2 Position with low spring tension against the Cassette profile 3 is held. In which The embodiment is also that with the tubular Housing 8 rotatably connected coupling element 16 as a sleeve formed on which the sleeve 18 is arranged concentrically is.
