Abstract

The blind (4) winds on and off a roller (5) in bearings (3) in a housing (1). A holder (2) secures the latter to the leaf of a window (6) etc. Protrusions (13, 16) on the housing lock into recesses (15) in the flanges (2a) of the holder, which is fixed to the leaf. The recess can be at the free edges of the holder flanges, which are of spring material thrust apart by insertion of the protrusions. The latter can be formed by lugs on the housing or the corners of the housing. There can be a single protrusion formed by a T-section rib. There can be a strip (11d) at the curtain bottom edge, with a lug fitting in a profiled component to hold it in the desired position.

Montagelage trotz einfacher Montage und Demontage und geringem Raumbedarf zu verbessern und auch ästhetischen Gesichtspunkten Rechnung zu tragen, um auch den nachträglichen Anbau an Fensterflügeln, Türflügeln oder dergleichen Bauteilen so zu ermöglichen, daß das äußere Design der Gesamtanordnung nicht beeinträchtigt wird, und die Handhabung ohne wesentliche Verminderung der lichten Höhe der Fenster- oder Türscheibe möglich ist.The invention has for its object to improve a system of this type by simple structure and yet safe positioning in the installation or assembly position despite simple assembly and disassembly and low space requirements and also to take aesthetic considerations into account in order to also retrofit window sashes , Door leaves or similar components so that the outer design of the overall arrangement is not impaired, and handling is possible without significantly reducing the clear height of the window or door pane.

Verschiedene Ausgestaltungen der Erfindung sind im Anspruch 1 und 7 hinsichtlich des Systems, in den Ansprüchen 8 und 9 hinsichtlich des Lagerkörpers und im Anspruch 12 hinsichtlich des Gehäuses gekennzeichnet. Weitere Ausbildungen der Erfindung sind in Unteransprüchen beansprucht und werden anhand der Zeichnung durch die nachfolgende Beschreibung noch beschrieben.Various configurations of the invention are characterized in claims 1 and 7 with regard to the system, in claims 8 and 9 with regard to the bearing body and in claim 12 with regard to the housing. Further embodiments of the invention are claimed in the subclaims and will be described in the following description with reference to the drawing.

Bei dem erfindungsgemäßen System wird eine Einheit bestehend aus dem Gehäuse, dem Aufwikkelorgan - sowie dem darauf aufzuwickelnden Wikkelgut - und Lagerkörpern an beiden Stirnseiten des Gehäuses gebildet. Bei einer Ausführung der Erfindung rastet ein Vorsprung, der sich insbesondere an mindestens einem der beiden Lagerkörper befindet, den aber auch das Gehäuse aufweisen kann, als Sperrmittel in eine Aussparung an einem Schenkel am Halteorgan ein. Die Rastwirkung wird begünstigt durch federelastische Ausbildung des Halteorgans. Zwei insbesondere um 90 zueinander abstehende Schenkel sind um ein gewisses Ausmaß an ihren Enden etwas weiter voneinander (über 90° hinaus) abspreizbar, so daß die oben genannte Einheit so in den vom Halteorgan gebildeten Raum eingeschoben oder insbesondere nach Einhaken an einem Ende eingeschwenkt oder eingesteckt werden kann, daß der Vorsprung am Lagerkörper bzw. Gehäuse in den Bereich der Aussparung am Halteorganschenkel gelangt, worauf die Spreizwirkung desselben aufgehoben wird und der Vorsprung als Sperrmittel in die Aussparung einrastet.In the system according to the invention, a unit consisting of the housing, the winding member - and the winding material to be wound thereon - and bearing bodies are formed on both end faces of the housing. In one embodiment of the invention, a projection, which is located in particular on at least one of the two bearing bodies, but which can also have the housing, engages as a locking means in a recess on a leg on the holding member. The latching action is favored by the resilient design of the holding member. Two legs, in particular at 90 to each other, can be spread a little further apart at their ends (beyond 90 ° ) so that the above-mentioned unit is pushed into the space formed by the holding member or, in particular, swung or inserted at one end after hooking can be that the projection on the bearing body or housing comes into the region of the recess on the holding member leg, whereupon the expansion effect of the same is canceled and the projection engages as a locking means in the recess.

Das Ausmaß des federelastischen Aufspreizens wird dann gering gehalten, wenn sich Aussparungen im Bereich der freien Schenkelende des Halteorgans befinden.The extent of the spring-elastic spreading is kept low if there are recesses in the area of the free leg end of the holding member.

Der Vorsprung ist insbesondere nasenförmig ausgebildet und steht von einer Außenfläche des Lagerkörpers ab; auch Ecken des Lagerkörpers können als solcher Vorsprung verwendet werden.The projection is in particular nose-shaped and protrudes from an outer surface of the bearing body; corners of the bearing body can also be used as such a projection.

Es empfiehlt sich, wenn ein freies Schenkelende des Halteorgans als Schwenklager für die oben genannte Baueinheit dient, während der andere davon abstehende Schenkel die Lagerkörper bzw. deren Vorsprünge mindestens teilweise an einer vom Schwenklager abgewandten Seite übergreift und dort die Rasteinrichtung aufweist, die zwischen dem betreffenden Schenkel und dem Lagerkörper wirksam ist. Dabei kann es sich zur Einsparung von Material empfehlen, das Gehäuse nur an denjenigen Seiten des Aufwickelorgans und der Lagerkörper anzuordnen, die nicht von Schenkeln des Halteorgans abgedeckt sind, was auch eine im Querschnitt im wesentlichen L-förmige Ausbildung des Gehäuses möglich macht. Vielfach empfiehlt sich aber eine wannenartige Ausbildung des Gehäuses, dessen Querschnitt dann im wesentlichen U-förmig ist.It is advisable if a free leg end of the holding member serves as a pivot bearing for the above-mentioned structural unit, while the other leg protruding therefrom overlaps the bearing bodies or their projections at least partially on a side facing away from the pivot bearing and there has the latching device which is between the relevant one Leg and the bearing body is effective. To save material, it may be advisable to arrange the housing only on those sides of the winding member and the bearing body that are not covered by legs of the holding member, which also makes an essentially L-shaped design of the housing possible. In many cases, however, a trough-like design of the housing is recommended, the cross section of which is then essentially U-shaped.

Die Rastverbindung stellt eine federelastische Verankerung der wannenartigen Baueinheit in der Einbaulage dar. Durch Aufwenden eines gewissen Druckes wird dafür gesorgt, daß die wannenartige Baueinheit in der Einbaulage in die Raststellung einschnappt. Durch Aufwenden eines gewissen Drucks kann die Raststellung auch wieder verlassen werden, um die wannenartige Baueinheit um das Schwenklager zurückzuschwenken und Zutritt zum Aufwickelorgan und Wickelgut im Inneren der Baueinheit zu erlangen.The latching connection represents a spring-elastic anchoring of the trough-like unit in the installed position. By applying a certain pressure, it is ensured that the trough-like unit snaps into the latched position in the installed position. By applying a certain pressure, the latching position can also be left again in order to pivot the tub-like unit back around the pivot bearing and to gain access to the winding member and material to be wound inside the unit.

Nach einer anderen Ausbildung der Erfindung ist der Vorsprung als von der Außenseite des Gehäuses abragender Befestigungssteg ausgebildet. Dabei greifen Aussparungen an Schenkelenden des Halteorgans an den freien Schenkelenden des Querbalkens des T-förmigen Befestigungsstegs derart an, daß auch hier eine Rastverbindung durch vorübergehendes Auseinanderspreizen der freien Schenkelenden und selbsttätiges Zurückschwenken nach Aufnahme der freien Schenkelenden des T-förmigen Befestigungsstegs in dafür vorgesehene Ausnehmungen im Halteorgan zustande kommt. Der Vorteil dieser Ausbildung besteht darin, daß auch im Querschnitt kreisförmige Gehäuse anwendbar sind, die insbesondere aus zwei halbschalenförmigen Mantelteilen zusammengesetzt sind. Beide Mantelteile werden durch die Lagerkörper an den Stirnenden des Gehäuses zusammengehalten.According to another embodiment of the invention, the projection is designed as a fastening web protruding from the outside of the housing. Recesses on the leg ends of the holding member on the free leg ends of the Crossbar of the T-shaped fastening web in such a way that a locking connection is also achieved here by temporarily spreading apart the free leg ends and automatically swinging back after receiving the free leg ends of the T-shaped fastening web in recesses provided for this purpose in the holding member. The advantage of this design is that circular cross-sectional housings can also be used, which are composed in particular of two half-shell-shaped casing parts. Both jacket parts are held together by the bearing body at the front ends of the housing.

Hierzu empfehlen sich Lagerkörper, die nach einer besonderen Ausbildung der Erfindung eine Reihe von Stützstegen aufweisen, die von einem Basisteil des Lagerkörpers in Axialrichtung des Aufwickelorgans ein Stück weit abstehen und derart angeordnet sind, daß deren radial äußere Abstützflächen zur Abstützung der radial innenliegenden Mantelfläche des Gehäuses dienen. Mit anderen Worten: Die Stützstege sind länges eines Kreises angeordnet, dessen Radius etwas geringer ist als der Innenradius des hohlzylindrischen Gehäuses.For this purpose, bearing bodies are recommended which, according to a special embodiment of the invention, have a series of support webs which protrude from a base part of the bearing body in the axial direction of the winding member and are arranged in such a way that their radially outer supporting surfaces for supporting the radially inner lateral surface of the housing to serve. In other words: the support webs are arranged along a circle, the radius of which is slightly smaller than the inner radius of the hollow cylindrical housing.

Bei einer anderen Ausbildung des erfindungsgemäßen Lagerkörpers, der vor allem für solche Rollokassetten als Baueinheit bestimmt ist, bei denen der vom Gehäuse und Halteorgan umschriebene Wickelraum im wesentlichen rechteckförmig ist, dient wie schon oben ausgeführt mindestens einer der Lagerkörper, besser beide Lagerkörper an den Stirnseiten des Gehäuses nicht nur zum drehbaren Lager des Aufwickelorgans und zum Befestigen des Gehäuses, sondern zusätzlich in einer Mehrfachfunktion auch zum Befestigen der Einheit am Halteorgan und/oder an dem betreffenden Bauteil, an dem der Vorhang anzutreffen ist. Die Lagerkörper sind dann Verbindungsmittel für alle anderen Teile der Baueinheit. Die Rastverbindung wird durch den vom Lagerkörper insbesondere seitlich abstehenden Vorsprung beispielsweise in Form einer Sperrnase hergestellt, welche in eine entsprechende Ausnehmung an der Innenseite des Halteorgans eingreift. Damit die Rast- bzw. Schnappverbindung zustande kommt, wird das entsprechende "Gegenlager" zweckmäßigerweise an einer solchen Stelle des Lagerkörpers und/oder des Gehäuses angeordnet, die sich in vergleichesweise großem Abstand zur Sperrnase befindet, so daß die federelastische Abspreizbarkeit des die Ausnehmung aufweisenden Schenkels des Halteorgans zu dem in das Gegenlager eingreifenden Schenkelteil des Halteorgans dieses Einschnappen begünstigt. Hierzu empfiehlt es sich nach einer besonderen Ausbildung der Erfindung, als Schwenklager für das Halteorgan einen entsprechenden Steg oder Ansatz an der Außenseite des Gehäuses oder Lagerkörper anzuordnen. In diesem Fall ist es überflüssig, daß die Bauteile miteinander verschraubt werden müssen, wodurch sich nicht nur ein ansprechenderes ästhetisches äußeres Erscheinungsbild mit vor allem glatten Flächen ergibt, sondern auch die Montage und Demontage wesentlich erleichtert und beschleunigt wird.In another embodiment of the bearing body according to the invention, which is primarily intended as a structural unit for roller blind cassettes in which the winding space circumscribed by the housing and holding member is essentially rectangular, as already explained above, at least one of the bearing bodies, better both bearing bodies on the end faces of the Housing not only for the rotatable bearing of the winding member and for fastening the housing, but also in a multiple function also for fastening the unit to the holding member and / or to the relevant component on which the curtain can be found. The bearing bodies are then connecting means for all other parts of the assembly. The latching connection is produced by the protrusion, in particular projecting laterally from the bearing body, for example in the form of a locking lug which engages in a corresponding recess on the inside of the holding member. So that the latching or snap connection takes place, the corresponding "counter bearing" is expediently arranged at such a point on the bearing body and / or the housing which is at a comparatively large distance from the locking lug, so that the resilient spreadability of the leg having the recess of the holding member to the leg part of the holding member engaging in the counter bearing favors this snap. For this purpose, it is recommended according to a special embodiment of the invention to arrange a corresponding web or shoulder on the outside of the housing or bearing body as a pivot bearing for the holding member. In this case, it is unnecessary that the components have to be screwed together, which not only results in a more appealing aesthetic appearance with, above all, smooth surfaces, but also makes assembly and disassembly much easier and faster.

Empfehlenswert ist auch eine weitere Ausbildung der Erfindung, bei der sich an der Außenseite eines Steges des Lagerkörpers eine insbesondere kegelige Aussparung befindet, in die ein Teil des Gehäuses eingepreßt wird, um das Gehäuse dort am Lagerkörper mit einfachen Mitteln des Einpressens zu befestigen.A further embodiment of the invention is also recommended, in which there is an in particular conical recess on the outside of a web of the bearing body, into which part of the housing is pressed in order to fasten the housing there to the bearing body with simple means of pressing.

Das erfindungsgemäße System basiert auf einer Mehrfachfunktion verschiedener miteinander zusammenwirkender Aggregate und Elemente. Es ist einfach zu bedienen, wartungsfrei und wirtschaftlich auch wegen seines kleinen Raumbedarfs praktisch an allen Stellen montierbar, an denen der Vorhang Abschirmungsaufgaben, beispielsweise das Abschirmen gegen Sonne und blendendes Tageslicht, durchführen soll. Ohne sichtbare Schraub-und Profilverbindungen kann das System harmonisch und glatt an die betreffenden Bauteile angepaßt werden, an denen es befestigt wird. Es bietet Ersatz beispielsweise für Außenjalousetten und ermöglicht auch die Anwendung solcher Vorhänge, die sehr dünn ausgebildet sind und trotz der abschirmenden Wirkung gegen Blendung noch freie Durchsicht erlauben. Mit dem Vorhang kann auch der Austausch von Luftzwischenräumen bzw. das Eintreten von Atmospherilien in den durch den Vorhang geschützte Räume erreicht werden.The system according to the invention is based on a multiple function of different interacting units and elements. It is easy to use, maintenance-free and, due to its small space requirement, it can be installed practically at any point where the curtain should perform shielding tasks, such as shielding against the sun and glare from daylight. Without visible screw and profile connections, the system can be harmoniously and smoothly adapted to the relevant components to which it is attached. It offers replacements for external venetian blinds, for example, and also enables the use of curtains that are very thin and, despite the shielding effect against glare, still allow a clear view. The curtain can also be used to exchange air gaps or to enter atmospheres in the spaces protected by the curtain.

Gemäß Figur 1 ist das im Querschnitt im wesentlichen L-förmige Halteorgan 2 mit dem oberen Schenkel 2a mit Hilfe von Schrauben, Nieten oder anderen Befestigungsorganen am unteren Quersteg eines Profilteils 8 befestigt, welcher einen Teil eines Fensterflügels 6 bildet. Die doppelwandige und aus Isolierglas bestehende Fensterscheibe 9 ist daran anschließend zwischen Dichtungsprofilen 10 eingespannt. An der Innenseite des Fensterflügels 6 ist innerhalb des Bereichs des Halteorgans 2 eine im wesentlichen kassetten- und wannenartige Baueinheit um den als Schwenklager dienenden Sperrsteg 14 zum Montieren verschwenkbar. Der Sperrsteg 14 verhindert in der Einbaulage auch das Aufklaffen und befindet sich daher am freien nach außen sichtbaren Ende des Schenkels 2a des Halteorgans 2, von dem er nach unten absteht. Das im Querschnitt im wesentlichen U-förmig profilierte Gehäuse 1 weist im Übergangsbereich zwischen dem oberen Schenkel 1 (Figur 3) und dem Verbindungssteg 1 zum unteren Schenkel 1 einen nach oben abstehenden nasen- oder hakenförmigen (im Querschnitt) Steg 13 auf, welcher mit dem Sperrsteg 14 zur Bildung des Schwenklagers zusammenwirkt. Dabei greift das im Querschnitt verdickte Ende des Steges 13 in die rillenförmige Vertiefung bzw. Ausnehmung 15 am Fuß des Sperrsteges 14 ein. An den Stirnseiten des U-Profils des Gehäuses 1 befinden sich Lagerkörper 3 mit jeweils einem Haltezapfen 3b mit einem als Drehsicherung dienenden quadratische Außenquerschnitt für die als Aufwickelorgan 5 dienende Trommel bzw. Wickelwelle, die zum Aufwickeln des bahnförmigen Vorhangs 4 dient. Der in Figur 1 vertikal vom oberen horizontalen Schenkel 2a nach unten abstehende vertikale Schenkel 2b des Halteorgans 2 weist in der Nähe des unteren freien Endes eine Ansnehmung 15 auf, welche in Verbindung mit dem als Sperrnase (im Querschnitt) ausgebildeten Vorsprung 16 am Rand des Lagerkörpers 3 dann eine Rasteinrichtung bildet, wenn die Baueinheit aus Gehäuse 1 und Lagerkörpern 3 in die Einbaulage eingeschwenkt ist, in welcher eine Durchtrittsöffnung 12 für den Vorhang 5, z.B. eine metallisierte Blendschutzfolie, zwischen dem freien Ende des unteren kürzeren Schenkels 1 des Gehäuses 1 und dem vertikalen Schenkel 2b des Halteorgans 2 frei bleibt. Am unteren Rand des Vorhangs 4 ist eine profilierte Abschlußleiste 11 d angeklebt, deren abstehende Sperrnase 11 in einer Führung eines Hohlkammerprofils 11 geführt ist und dessen Abfallen verhindert.According to FIG. 1, the essentially L-shaped holding member 2 is attached to the upper leg 2a by means of screws, rivets or other fastening members on the lower transverse web of a profile part 8, which forms part of a window sash 6. The double-walled window pane 9 made of insulating glass is then clamped between sealing profiles 10. On the inside of the window sash 6, an essentially cassette-like and trough-like structural unit can be pivoted around the locking web 14 serving as a pivot bearing for mounting within the region of the holding member 2. The locking web 14 also prevents gaping in the installed position and is therefore located at the free, externally visible end of the leg 2a of the holding member 2, from which it protrudes downward. The housing 1, which is essentially U-shaped in cross section, has in the transition region between the upper leg 1 (FIG. 3) and the connecting web 1 to the lower leg 1 an upwardly projecting nose or hook-shaped (in cross section) web 13, which is connected to the Locking web 14 cooperates to form the pivot bearing. The cross-sectionally thickened end of the web 13 engages in the groove-shaped recess or recess 15 at the foot of the locking web 14. On the end faces of the U-profile of the housing 1 there are bearing bodies 3, each with a holding pin 3b with a square outer cross section serving as a rotation lock for the drum or winding shaft serving as the winding member 5, which serves for winding the web-shaped curtain 4. The vertical leg 2b of the holding member 2 projecting vertically downward from the upper horizontal leg 2a in FIG. 1 has a recess 15 in the vicinity of the lower free end, which in connection with the projection 16 designed as a locking lug (in cross section) on the edge of the bearing body 3 then forms a latching device when the assembly comprising housing 1 and bearing bodies 3 is pivoted into the installation position, in which a passage opening 12 for the curtain 5, for example a metallized anti-glare film, between the free end of the lower shorter leg 1 of the housing 1 and the vertical leg 2b of the holding member 2 remains free. At the lower edge of the curtain 4 a profiled end strip 11 d is glued, the projecting locking lug 11 is guided in a guide of a hollow chamber profile 11 and prevents it from falling off.

Gemäß Figuren 2 und 2a ist in die Enden der Hohlkammer 11 des Hohlkammerprofils 11 je ein Gleitkörper 11a aus Kunststoff eingesteckt, von dem je ein Gleitsteg 11 axial absteht, der in einem Führungsschlitz 20 der betreffenden seitlichen Führungsleiste 19 gleitbar geführt ist. Parallel zu dem Führungsschlitz 20 verläuft ein weiterer Führungsschlitz 21 in der Führungsleiste 19; dort wird der Seitenrand 4b des Vorhangs 4 um die Führungsbreite A im Abstand von der Fensterscheibe 9 geführt. In der Haltenut 10m ist ein elastisch verformbares Profil 10a gehalten, das sich an die Fensterscheibe 9 anschmiegt und den Zwischenraum 10b zwischen der Führungsleiste 19 und der Glasscheibe 9 schließt.According to FIGS. 2 and 2a, a sliding body 11a made of plastic is inserted into the ends of the hollow chamber 11 of the hollow chamber profile 11, from each of which a sliding web 11 projects axially, which is slidably guided in a guide slot 20 of the lateral guide strip 19 in question. Another guide slot 21 runs in the guide bar 19 parallel to the guide slot 20; there the side edge 4b of the curtain 4 is guided by the guide width A at a distance from the window pane 9. An elastically deformable profile 10a is held in the holding groove 10m, which nestles against the window pane 9 and closes the intermediate space 10b between the guide strip 19 and the glass pane 9.

In der in Figur 3 schematisch dargestellten Einbaulage rastet daher der Vorsprung 16 in die Ausnehmung 15 ein. Dabei stößt das freie Ende 1s des oberen Schenkels 1 des Gehäuses 1 an der Innenseite des vertikalen Schenkels 2b des Halteorgans 2 an, um dort eine Stützfunktion zu bilden und dafür zu sorgen, daß die beiden zueinander schwenkbaren Vorrichtungsaggregate im Bereich des Schwenklagers 13, 14, 15 nicht auseinanderfallen.In the installation position shown schematically in FIG. 3, the projection 16 therefore snaps into the recess 15. The free end 1s of the upper leg 1 of the housing 1 abuts the inside of the vertical leg 2b of the holding member 2 in order to form a support function there and to ensure that the two device assemblies which can be pivoted relative to one another in the region of the pivot bearing 13, 14, 15 do not fall apart.

Die federelastische Verankerung an der Rasteinrichtung wird durch entsprechende Dimensionierung und sich zu einem gewissen Grade federelastisch verhaltendes Material, beispielsweise Aluminium, für die Profilteile realisiert. Bei der Version von Figur 1 übernimmt der oben vom oberen Gehäuseschenkel 1 nach oben abstehende Steg 17 in Verbindung mit dem eine Auflauffläche bildenden und vom oberen Schenkel 2a des Halteorgans 2 nach unten abstehenden Steg 18 die Stützfunktion. An der in Figur 3 oberen rechten Ecke, an der der obere horizontale Schenkel 1 mit dem vertikalen Verbindungssteg 1 des Gehäuses 1 zusammenstoßen, ragt außen die im Querschnitt hakenförmige Nase als Steg 13 nach oben. Sie wird hinter dem ein Schwenklager bildenden im Querschnitt verdickten und abgerundeten Ende des Sperrstegs 14 am freien Ende des oberen horizontalen Schenkels 2c eingeklinkt. Insofern kann das Gehäuse 1 um dieses Schwenklager verschwenkt werden, wenn z.B. das Wickelgut 4a einzuführen ist.The resilient anchoring to the locking device is realized by appropriate dimensioning and to a certain extent resilient material, for example aluminum, for the profile parts. In the version of FIG. 1, the web 17 protruding upward from the upper housing leg 1 in connection with it forms a run-up surface the and from the upper leg 2a of the holding member 2 protruding web 18 down the support function. At the upper right corner in FIG. 3, at which the upper horizontal leg 1 collides with the vertical connecting web 1 of the housing 1, the nose, which is hook-shaped in cross section, projects upwards as a web 13. It is latched in at the free end of the upper horizontal leg 2c behind the end of the locking web 14 which is thickened in cross section and is rounded. In this respect, the housing 1 can be pivoted about this pivot bearing if, for example, the winding material 4a is to be introduced.

Am unteren Ende ist der Vorhang 4 durch eine auch als Gewicht dienende Abschlußleiste 11 abgeschlossen.At the lower end, the curtain 4 is closed by a cover strip 11 which also serves as a weight.

Zur Lagerung der Ende des Aufwickelorgans 5 dienen Haltezapfen 3b, die sich gemäß Figur 4 in Axialrichtung ein Stück weit vom Lagerkörper 3 und zwar von dessen Basisteil 3f nach innen, d.h. in den Innenraum des rinnenförmigen Gehäuses 1, erstrecken. Bei dieser Ausbildung besteht das Gehäuse 1 aus einem im Querschnitt im wesentlichen U-förmigen Profil aus insbesondere Aluminium mit einem vertikalen Verbindungssteg 1 und zwei sich daran anschließenden Schenkeln 1 und 1 c. Im unteren Teil ist der Verbindungssteg 1 innen mit einer Ausnehmung 16 versehen, ebenso wie an der nach innen gewendeten Seite des vertikalen Schenkels 2b des im Querschnitt im wesentlichen L-förmigen Halteorgans 2 eine solche sich in Axialrichtung erstreckende Ausnehmung 16 angeordnet ist, deren Funktion im folgenden und insbesondere anhand von Figur 5 noch näher erläutert wird.To support the end of the take-up member 5, there are holding pins 3b which, according to FIG. 4, extend a little in the axial direction from the bearing body 3, namely from the base part 3f inwards, i.e. extend into the interior of the channel-shaped housing 1. In this embodiment, the housing 1 consists of a cross-section which is essentially U-shaped, made in particular of aluminum, with a vertical connecting web 1 and two adjoining legs 1 and 1 c. In the lower part, the connecting web 1 is provided on the inside with a recess 16, as is such an axially extending recess 16, the function of which is arranged in the inward-facing side of the vertical leg 2b of the essentially L-shaped holding member 2 in cross section following and in particular with reference to Figure 5 is explained in more detail.

Der Lagerkörper 3 weist im oberen Bereich zwei sich ebenso wie der Haltezapfen 3b axial erstreckende Stützstege 3c auf, welche zur Abstützung des oberen horizontalen Schenkels 1 des Gehäuse 1 dienen. Dieser Schenkel 1 kann dort auf den Stützstegen 3c angeschraubt werden, wozu die Stützstege 3c Gewindebohrungen 3c1 aufweisen. Wird die in Figur 3 gezeigte Einheit mit dem Gehäuse 1 umgekehrt auf den in Figur 4 gezeigten Lagerkörper 3 axial aufgesetzt, dann greift dessen Vorsprung 16 in die Ausnehmung 15 des Verbindungsstegs 1 ein (hierbei sei angenommen, daß das Halteorgan 2 noch nicht aufgesetzt ist). Nach Einsetzen des Aufwickelorgans 5 dienen die Durchführungskanäle 3e, die aus dem zentralen im wesentlichen zylindrischen Aufnahmeraum 3d nach unten und daher etwa radial aus dem Aufnahmeraum 3d und aus dem Lagerkörper 3 nach außen führen, zum Hindurchführen beispielsweise einer Zugschnur, Kordel oder dergleichen, welche zum Drehen des Aufwickelorgans 5 und daher zum Ausgeben bzw. Aufwickeln des Vorhangs 4 dient (die Zugschnur ist hier nicht dargestellt). Der Aufnahmeraum 3d ist zwischen den Durchführungskanälen 3e durch einen Steg 3g abgeschlossen, während die Ränder durch Seitenwände 3h gebildet werden, die sich bis zum unteren Rand 3i des Lagerkörpers 3 hinziehen, in dessen Nähe sich die Vorsprünge 16 befinden. Der obere Rand 3i des Basisteils 3f des Lagerkörpers 3 kann soweit hochgezogen sein, daß er auch den oberen horizontalen Schenkel 2a des Halteorgans 2 seitlich abdeckt, so daß die Baueinheit mit dem Halteorgan 2 zu einer stabförmigen Kassetteneinheit ergänzt ist.The bearing body 3 has, in the upper region, two support webs 3c which, like the holding pin 3b, extend axially and serve to support the upper horizontal leg 1 of the housing 1. This leg 1 can be screwed onto the support webs 3c there, for which purpose the support webs 3c have threaded bores 3c1. If the unit shown in FIG. 3 with the housing 1, conversely, is placed axially on the bearing body 3 shown in FIG. 4, then its projection 16 engages in the recess 15 of the connecting web 1 (it is assumed here that the holding member 2 has not yet been placed). . After insertion of the take-up member 5, the feed-through channels 3e, which lead downward from the central, essentially cylindrical receiving space 3d and therefore approximately radially outward from the receiving space 3d and out of the bearing body 3, are used for passing a pull cord, cord or the like, for example Rotation of the winding member 5 and therefore serves to output or wind up the curtain 4 (the pull cord is not shown here). The receiving space 3d is closed off between the lead-through channels 3e by a web 3g, while the edges are formed by side walls 3h which extend to the lower edge 3i of the bearing body 3, in the vicinity of which the projections 16 are located. The upper edge 3i of the base part 3f of the bearing body 3 can be pulled up to such an extent that it also laterally covers the upper horizontal leg 2a of the holding member 2, so that the structural unit with the holding member 2 is supplemented to form a rod-shaped cassette unit.

Nachdem die Verbindung des im Querschnitt im wesentlichen U-förmigen Gehäuses 1 mit den beiden Lagerkörpern 3 an deren Stirnenden auf die oben erwähnte Weise zustandegekommen und das Aufwickelorgan 5 mit dem Wickelgut 4a eingesetzt ist, wird der Steg 13 in das als ergänzendes Abdeckelement wirksame Halteorgan 2 hinter dem Sperrsteg 14 eingesetzt und soweit verschwenkt, bis der Schenkel 2b praktisch die gesamte offene Seite an den Enden der horizontalen Schenkel 1 b, 1c des rinnenförmigen Gehäuses 1 abdeckt, so daß lediglich noch die Durchtrittsöffnung 12 für den Durchtrit des Vorhangs 4 offen ist. Das Halteorgan 2 wird dann dadurch in der Montagestellung gehalten, daß der Schenkel 2b so weit in die vertikale Stellung gebracht wird, daß der als Sperrmittel dienende Vorsprung 16 in die Ausnehmung 15 einschnappt bzw. einrastet.After the connection of the housing 1, which is essentially U-shaped in cross section, to the two bearing bodies 3 at their ends in the above-mentioned manner and the winding member 5 with the winding material 4a is inserted, the web 13 is inserted into the holding member 2, which acts as a supplementary cover element inserted behind the locking bar 14 and pivoted until the leg 2b practically covers the entire open side at the ends of the horizontal legs 1b, 1c of the channel-shaped housing 1, so that only the passage opening 12 is still open for the passage of the curtain 4. The holding member 2 is then held in the assembly position in that the leg 2b is brought into the vertical position so far that the projection 16 serving as a locking means snaps into the recess 15 or snaps into place.

Begünstigt wird diese Schnappverbindung durch die in Figur 5 gezeigte bevorzugte Ausbildung, wonach der Vorsprung 16 am unteren Ende um den Rastwinkel von beispielsweise zwischen 10 und 30 zur Horizontalen bzw. zum unteren Rand 3i geneigt ist, so daß eine entsprechend geneigte Fläche eine kleine Sperrnase 2b1 unterhalb der Aussparung 15 des Schenkels 2b bildet und hinter die schräge Fläche des Vorsprungs 16 einrastet.This snap connection is favored by the preferred embodiment shown in FIG. 5, according to which the projection 16 at the lower end is inclined by the detent angle of, for example, between 10 and 30 to the horizontal or to the lower edge 3i, so that a correspondingly inclined surface has a small locking lug 2b1 forms below the recess 15 of the leg 2b and engages behind the inclined surface of the projection 16.

Der am Lagerkörper 3 vorgesehene seitlich ausladende Vorsprung 16, der mit der Ausnehmung 15 im Halteorgan 2 als Schnapp- bzw. Rastverbindung zusammenwirkt, könnte auch in umgekehrter Konstruktion realisiert werden mit einem Vorsprung am Halteorgan 2 und einer entsprechenden Ausnehmung am Lagerkörper 3, sofern die federelastische Rast- bzw. Schnappwirkung nicht verlorengeht.The laterally protruding projection 16 provided on the bearing body 3, which cooperates with the recess 15 in the holding member 2 as a snap or latching connection, could also be realized in the reverse construction with a projection on the holding member 2 and a corresponding recess on the bearing body 3, provided that the spring elastic The locking or snap action is not lost.

Bei der vereinfachten Ausbildung von Figur 6 ist das Halteorgan 2 im Querschnitt wiederum im wesentlichen L-förmig profiliert, weist aber an beiden freien Schenkelenden abgewinkelte Sperrstege 14 auf, die als Schwenklager und/oder als Rasteinrichtung wirken können, wenn sie die diagonal gegenüberliegenden Ecken des Lagerkörpers 3 umgreifen, welche die Vorsprünge 16 bilden, die in den abgerundeten Ausnehmungen 15 am Fußpunkt der Sperrstege 14 einschnappen. Bei dieser Ausbildung würde sogar genügen, wenn das hier nicht dargestellte Gehäuse im Querschnitt nur im wesentlichen L-förmig ausgebildet ist, um den vom Halteorgan 2 freigelassenen Umfang an den Rändern des Lagerkörpers 3 abzudecken.In the simplified embodiment of Figure 6, the holding member 2 is in turn substantially L-shaped in cross-section, but has angled locking webs 14 on both free leg ends, which can act as a pivot bearing and / or as a locking device if they diagonally opposite corners of the Reach around the bearing body 3, which form the projections 16, which snap into the rounded recesses 15 at the base of the locking webs 14. This training would even suffice if this wasn't housing shown in cross section is only substantially L-shaped to cover the circumference left free by the holding member 2 at the edges of the bearing body 3.

Gemäß Figur 7 ist eine bevorzugte Ausbildung im Querschnitt gezeigt. Danach ist der Innenraum des Gehäuses 1 im Querschnitt kreisförmig mit dem Radius R. Die Wandstärke der beiden Mantelteile 1 m und 1 nehmen jedoch von den schmalen Enden im Bereich der Durchtrittsöffnung 12 zu den breiteren Enden 1 m1 und 1 n1 im Bereich der Verbindungsstelle 1 p zu. An dieser Verbindungsstelle 1 wird eine Art "Feder-Nut-Verbindung" 10 zwischen den beiden Mantelteilen 1a, 1 gebildet. Hierdurch wird beim Montieren ein Verrutschen bzw. radiales Verlagern der beiden Mantelteile 1 m, 1 n in Bezug zueinander verhindert, ehe eine genügende Verankerung am Lagerkörper 3 erzielt ist.According to Figure 7, a preferred embodiment is shown in cross section. Thereafter, the interior of the housing 1 is circular in cross section with the radius R. However, the wall thickness of the two jacket parts 1 m and 1 increase from the narrow ends in the area of the passage opening 12 to the wider ends 1 m1 and 1 n1 in the area of the connection point 1 p to. At this connection point 1 a kind of "tongue and groove connection" 10 is formed between the two jacket parts 1a, 1. This prevents slipping or radial displacement of the two jacket parts 1 m, 1 n in relation to one another during assembly before sufficient anchoring to the bearing body 3 is achieved.

Bei der Alternative der Figur 7 weist der obere horizontale Schenkel 2a des Halteorgans 2 im Bereich des ein Schwenklager bildenden Lagersitzes an der Innenseite eine nasenförmige Erhebung 14a auf, wodurch beim Einführen des Vorsprungs 16b des freien Schenkelendes des T-förmigen Befestigungsstegs 16 in die Ausnehmung 15 am Fußpunkt des oberen Sperrsteges 14 eine bessere Führung im Lagersitz gewährleistet werden kann, wenn das Gehäuse 1 um dieses Schwenklager des Lagersitzes herum in den Zwischenraum zwischen die beiden horizontalen Schenkel 2a und 2c bis in den Lagersitz hineingeschwenkt und dort verrastet wird, der vom Sperrsteg 14 und der betreffenden Ausnehmung 15 am freien unteren Schenkelende gebildet wird, in die der Vorsprung 16a eingeschnappt wird.In the alternative of FIG. 7, the upper horizontal leg 2a of the holding member 2 has a nose-shaped elevation 14a on the inside in the region of the bearing seat forming a pivot bearing, so that when the projection 16b of the free leg end of the T-shaped fastening web 16 is inserted into the recess 15 At the base of the upper locking web 14, better guidance in the bearing seat can be ensured if the housing 1 is pivoted around this pivot bearing of the bearing seat into the space between the two horizontal legs 2a and 2c and into the bearing seat and is locked there by the locking web 14 and the relevant recess 15 is formed at the free lower leg end into which the projection 16a is snapped.

Das Halteorgan 2 und das Gehäuse 1 werden beispielsweise aus Aluminium hergestellt. Die Erfindung ist hierauf aber nicht beschränkt. Auch Kunststoffmaterialien sind hierfür geeignet.The holding member 2 and the housing 1 are made of aluminum, for example. The invention is not limited to this. Plastic materials are also suitable for this.

Der Verbindungsschenkel 2b des Halteorgans 2 ist mittels der Befestigungsschraube 25 an der Wand W' angeschraubt, ehe die Rollokassette in die Montagestellung gebracht wird. Alternativ kann das Halteorgan 2 auch mittels des in unterbrochenen Linien angedeuteten Befestigungsorgans 26 oben angeschraubt werden, wodurch zusätzlich die Spannung auf die Lagersitze verstärkt wird. Zum Demontieren ist es lediglich erforderlich, die Rollokassette, d.h. das Gehäuse 1 ein Stück weit in Pfeilrichtung um das durch den Lagersitz bei 14a gebildete Schwenklager zu schwenken und den Druck der beiden Lagersitze auf den Befestigungssteg 16 zu überwinden, wodurch der untere Vorsprung 16a von seinem Lagersitz freikommt und dann die Rollokassette aus dem Halteorgan 2 herausgenommen werden kann.The connecting leg 2b of the holding member 2 is screwed onto the wall W 'by means of the fastening screw 25 before the roller blind cassette is brought into the assembly position. Alternatively, the holding member 2 can also be screwed on by means of the fastening member 26 indicated in broken lines, which additionally increases the tension on the bearing seats. To dismantle it is only necessary to remove the roller cassette, i.e. the housing 1 a little in the direction of the arrow to pivot the pivot bearing formed by the bearing seat at 14a and to overcome the pressure of the two bearing seats on the fastening web 16, as a result of which the lower projection 16a is released from its bearing seat and then the roller blind cassette is removed from the holding member 2 can be.

Gemäß Figur 8 ist das im Querschnitt im wesentlichen hohlzylindrische Gehäuse 1 über den Befestigungssteg - den Vorsprung 16 - ,der von einer Außenfläche des Gehäuses 1 absteht, im Halteorgan 2 gelagert, das entweder an der oberen Wand W oder alternativ an der Seitenwand W' einer Fensternische befestigt sein kann. Vom vertikalen Schenkel 2b stehen zwei Schenkel 2a, 2c gabelartig ab, so daß sich im Querschnitt im wesentlichen ein U-Profil ergibt mit einem längeren oberen Schenkel 2a und einem kürzeren unteren Schenkel 2c. An den Schenkelenden befinden sich als Lagersitze die Ausnehmungen 15.According to FIG. 8, the housing 1, which is essentially hollow cylindrical in cross section, is mounted in the holding member 2 via the fastening web - the projection 16 - which protrudes from an outer surface of the housing 1, either on the upper wall W or alternatively on the side wall W ' Window niche can be attached. Two legs 2a, 2c protrude from the vertical leg 2b in a fork-like manner, so that in cross section there is essentially a U-profile with a longer upper leg 2a and a shorter lower leg 2c. At the leg ends there are the recesses 15 as bearing seats.

In die obere rinnenförmige Ausnehmung 15 ist der Vorsprung 16b des T-förmigen Befestigungsstegs bzw. Vorsprung 16 des Gehäuses 1 eingesetzt. Da beide Schenkel 2a, 2c federelastisch sind, kann durch Druck der Vorsprung 16a des unteren freien Schenkelendes des Befestigungsstegs in die untere Ausnehmung 15 eingeschnappt werden. Durch die Durchtrittsöffnung 12 insbesondere in Form eines sich axial hinziehenden Schlitzes kann der Vorhang 4 mit Hilfe einer unteren Abschlußleiste 11 oder eines Gewichtes am unteren Ende des Vorhangs 4 aus dem Innenraum des Gehäuses 1 herausgezogen werden.The projection 16b of the T-shaped fastening web or projection 16 of the housing 1 is inserted into the upper groove-shaped recess 15. Since both legs 2a, 2c are resilient, the projection 16a of the lower free leg end of the fastening web can be snapped into the lower recess 15 by pressure. Through the passage opening 12, in particular in the form of an axially extending slot, the curtain 4 can be pulled out of the interior of the housing 1 with the aid of a lower end strip 11 or a weight at the lower end of the curtain 4.

Ein bevorzugter Lagerkörper 3 ist schematisch in Figuren 9 und 10 gezeigt. Er schließt eine Stirnseite des im wesentlichen hohlzylindrischen Mantels des Gehäuses 1 ab. Ebenso wie sich der Haltezapfen 3b in Axialrichtung erstreckt, sind auch um jeweils 90° versetzt an der Innenseite des Lagerkörpers 3 angeordnete Stützsegmente bzw. Stützstege 3c ausgerichtet, an deren radial äußeren Abstützflächen 3c2 sich die radial innere Mantelfläche 1 mit dem Radius R abstützt. Die Gewindebohrungen 3c1 dienen zum Festschrauben der beiden im wesentlichen im Querschnitt halbkreisförmigen Mantelteile 1m, 1 (Figur 7), die an einem Ende an der Verbindungsstelle 1 zusamenstoßen, sich am anderen Ende aber im Abstand voneinander befinden, um die Durchtrittsöffnung 12 für den Durchtritt des Vorhangs 4 zu formen. Jeder der beiden Mantelteile 1m, 1 n wird durch eine Halteschraube X am Stützsteg 3c festgeschraubt, wodurch einerseits der Lagerkörper 3 mit dem Gehäuse 1 verbunden ist und die beiden Mantelteile 1m, In andererseits durch den Lagerkörper 3 zusammengehalten werden. Auch hier befindet sich im Zentrum des im wesentlichen zylindrischen Aufnahmeraums 3d ein als Drehsicherung dienender Haltezapfen 3b und auch hier dienen im wesentlichen radial zur Achse des Haltezapfens 3b verlaufende Durchführungskanäle 3e zum Hindurchführen einer Zugschnur oder dergleichen.A preferred bearing body 3 is shown schematically in FIGS. 9 and 10. It closes an end face of the substantially hollow cylindrical shell of the housing 1. Just as the holding pin 3b extends in the axial direction, support segments or support webs 3c arranged on the inside of the bearing body 3 are also offset by 90 °, on the radially outer support surfaces 3c2 of which the radially inner lateral surface 1 is supported with the radius R. The threaded bores 3c1 are used to screw down the two jacket parts 1m, 1 (FIG. 7), which are essentially semicircular in cross-section and which meet at one end at the connection point 1, but are at a distance from one another at the other end, around the passage opening 12 for the passage of the Shaping curtain 4. Each of the two jacket parts 1m, 1n is screwed to the support web 3c by a retaining screw X, whereby on the one hand the bearing body 3 is connected to the housing 1 and the two jacket parts 1m, In are held together by the bearing body 3. Here, too, there is a holding pin 3b serving as a rotation lock in the center of the essentially cylindrical receiving space 3d, and here, too, lead-through channels 3e, which run essentially radially to the axis of the holding pin 3b, serve for passing a pull cord or the like.

Die Gesamteinheit, bestehend aus beiden Mantelteilen 1 m, 1 n sowie zwei Lagerkörpern 3 an den Stirnseiten des Gehäuses 1 und dem im Inneren axial gelagerten Aufwickelorgan 5, bilden eine kassettenartige Baueinheit.The entire unit, consisting of two jacket parts 1 m, 1 n and two bearing bodies 3 on the end faces of the housing 1 and the winding member 5 axially mounted inside, form a cassette-like unit.

Gemäß Figur 11 weist der Lagerkörper 3 eine ähnliche Ausbildung wie der Lagerkörper von Figur 4 auf. Im Unterschied zum letztgenannten fehlen die Vorsprünge 16. Dafür ist beispielsweise mittels eines Körners eine Vertiefung an der Unterseite des mittleren Steges 3g zwischen den nach unten führenden Durchführungskanälen 3e aus dem zylindrischen Aufnahmeraum 3d angeordnet. Diese Vertiefung ist eine im wesentlichen kegelige Aussparung 3k. Sie dient dem anhand der Figur 12 erläuterten Zweck.According to Figure 11, the bearing body 3 has a similar design as the bearing body of Figure 4. In contrast to the latter, the projections 16 are absent. For this purpose, for example, a recess is arranged on the underside of the central web 3g between the through-passage channels 3e leading from the cylindrical receiving space 3d by means of a punch. This depression is an essentially conical recess 3k. It serves the purpose explained with reference to FIG. 12.

In die kegelige Aussparung 3k ist ein Vorsprung 1 des Gehäuses 1 eingedrückt, nachdem das Stirnende des Gehäuses 1 bis an den Basisteil 3f herangeführt ist. Der Vorsprung 1 wird beispielsweise mittels eines außen an der betreffenden Stelle auf das Gehäuse 1 aufgesetzten Preßdorns durch Eindrücken von Gehäusematerial in die vertiefte Aussparung 3k hergestellt. Die dabei entstehende dornartige Ausbeulung des Gehäusematerials, beispielsweise Aluminium, füllt die kegelige Aussparung 3k praktisch aus und stellt eine auf Abscherung beanspruchbare Verbindung zwischen dem Gehäuse 1 und dem Lagerkörper 3 her. Hierdurch wird ein Festschrauben des Gehäuses 1 auf beispielsweise den Stützstegen 3c überflüssig. Dennoch sitzt das Gehäuse 1 fest auf dem Lagerkörper 3, so daß eine feste Baueinheit hergestellt ist. Die Dicke des Lagerkörpers 3 kann auf beispielsweise die Hälfte vermindert werden, so daß die Durchführungskanäle 3e wie bei der Ausbildungsform von Figur 4 nach außen offen sind und sich durch diesen Verzicht auf geschlossene Durchführungskanäle einfacherere Druckgußformen für die Herstellung des Lagerkörpers 3 ergeben. Außerdem werden störende Schraubenköpfe an der Außenseite des Gehäuses 1 bzw. Lagerkörpers 3 vermieden. Es empfiehlt sich daher, die Durchführungskanäle 3e an der vom Basisteil 3f abgewandten Seite des Lagerkörpers 3 offen zu lassen. Der Haltezapfen 3b mit quadratischem Querschnitt dient als Drehsicherung, weist aber im Zentrum eine zylindrische Bohrung 3b1 auf.A projection 1 of the housing 1 is pressed into the conical recess 3k after the front end of the housing 1 has been brought up to the base part 3f. The projection 1 is produced, for example, by means of a pressing mandrel placed on the housing 1 at the relevant location by pressing housing material into the recessed recess 3k. The resulting thorn-like bulge of the housing material, for example aluminum, practically fills the conical recess 3k and establishes a connection between the housing 1 and the bearing body 3 that can be sheared. As a result, screwing the housing 1 onto, for example, the support webs 3c becomes superfluous. Nevertheless, the housing 1 sits firmly on the bearing body 3, so that a solid structural unit is produced. The thickness of the bearing body 3 can be reduced to half, for example, so that the through-channels 3e are open to the outside, as in the embodiment of FIG. 4, and this dispensing with closed through-channels results in simpler die-casting molds for the production of the bearing body 3. In addition, disturbing screw heads on the outside of the housing 1 or bearing body 3 are avoided. It is therefore advisable to leave the lead-through channels 3e open on the side of the bearing body 3 facing away from the base part 3f. The holding pin 3b with a square cross section serves as a rotation lock, but has a cylindrical bore 3b1 in the center.

Bei der Ausbildung von Figur 13 ist das Gehäuse 1 wiederum wie in Figur 7 aus zwei Mantelteilen 1m, 1 an der Stoßstelle 1 zusammengesetzt. Vom oberen Mantelteil 1m stehen zwei im Querschnitt warzenartige Vorsprünge 16 im Abstand voneinander radial ab. Diese dienen zum Festhalten des Gehäuses 1 am Halteorgan 2 dadurch, daß dessen Schenkel 2a, 2c beim Eindrükken der Vorsprünge 16 in die gerundeten Aussparungen 15 an den Schenkelenden die Schenkel 2a, 2c kurz auseinanderspreizen, bis die Vorsprünge 16 in die Aussparungen 15 einrasten. Das Gehäuse 1 wirkt mit dessen radial abstehenden Vorsprüngen 16 daher beim Befestigen als "Aufspreizkörper" für die Schenkel 2a, 2c, d.h. das Halteorgan 2.13, the housing 1 is again composed of two jacket parts 1m, 1 at the joint 1, as in FIG. Two projections 16, which are wart-like in cross-section, protrude radially from one another from the upper casing part 1m. These serve to hold the housing 1 on the holding member 2 in that its legs 2a, 2c briefly spread apart the legs 2a, 2c when the projections 16 are pressed into the rounded recesses 15 at the leg ends until the projections 16 snap into the recesses 15. The housing 1, with its radially protruding projections 16, therefore acts as an "expansion body" for the legs 2a, 2c, i.e. the holding member 2.
