Description

Die Erfindung betrifft ein Aussteifungselement für einen Rollladenkasten.The invention relates to a stiffening element for a roller shutter box.

Aus der EP 1 705 335 A2 ist ein Rollladenkasten bekannt, der an allen vier Seitenflächen aus Kunststoff-Hohlprofilen gebildet ist. Ein solcher Rollladenkasten ist leicht montierbar. Er ist durch ineinander greifende Profile luftdicht auszubilden und kann mit zusätzlich eingesetzten Wärmedämmelementen gedämmt werden, um Kältebrücken im Bereich des Rollladenkastens zu vermeiden. Weiterhin können durch entsprechende Profilgestaltungen vielfältige Möglichkeiten vorgesehen werden, um Revisionsklappen an der Unterseite oder an der der Gebäudeinnenseite zugewandten Seite auszubilden.From the EP 1 705 335 A2 is a roller shutter box is known, which is formed on all four side surfaces of plastic hollow sections. Such a shutter box is easy to install. It is airtight form by interlocking profiles and can be insulated with additionally used thermal insulation elements to avoid cold spots in the area of the roller shutter box. Furthermore, various options can be provided by appropriate profile designs to form inspection flaps on the underside or on the inside of the building side facing.

Zum Anschluss des Rollladenkastens an die Gebäudedecke sind aus der EP 1 775 415 A2 spezielle Anschlussprofile bekannt, auf die das Deckelprofil des Rollladenkastens aufgerastet werden kann. Das Bodenprofil wird mit dem Blendrahmen des Fensters verbunden, so dass die statische Verbindung zwischen dem oberen Abschnitt des Blendrahmens und der Decke über den Rollladenkasten erfolgt. Bei kurzen Rollladenkästen ist die Steifigkeit der stirnseitig angebrachten Kopfzeile ausreichend, um auf den oberen Bereich des Fensters wirkende Windlasten oder dergleichen vom Blendrahmen in die Decke abzuleiten. Bei größeren Fensterbreiten hingegen müssen zusätzliche Aussteifungselemente, sogenannte Statikkonsolen, montiert werden, um Kräfte vom Blendrahmen in die Decke abzuleiten. Die Besonderheit des Anwendungsfall besteht darin, dass die Befestigungslinie des Rollladenkastens an der Decke näher an der innenraumseitigen Seitenwand angeordnet ist, und die Befestigungslinie des Bodens am Blendrahmen in einem mittleren Bereich liegt, so dass ein Tiefenversatz entsteht, der überbrückt werden muss. Eine direkte Verbindung der Verbindungsstellen ist zudem nicht möglich, da ja der aufgewickelte Rollladenpanzer umgangen werden muss.To connect the shutter box to the building ceiling are from the EP 1 775 415 A2 special connection profiles known to which the lid profile of the shutter box can be snapped. The floor profile is connected to the frame of the window, so that the static connection between the upper portion of the frame and the ceiling on the roller shutter box takes place. For short roller shutter boxes, the rigidity of the front-mounted head line is sufficient to dissipate acting on the upper region of the window wind loads or the like from the frame in the ceiling. For larger window widths, however, additional stiffening elements, so-called static brackets, must be mounted in order to divert forces from the frame to the ceiling. The special feature of the application is that the attachment line of the shutter box is arranged on the ceiling closer to the inside side wall, and the fastening line of the bottom of the frame lies in a central region, so that a depth offset is created, which must be bridged. A direct connection of the joints is also not possible, since the wound roller shutter must be bypassed.

Herkömmlich werden bügelförmige Statikkonsolen aus Metall als Aussteifungselemente verwendet, die im Rollladenkasten fest mit dem Blendrahmen verschraubt werden, so dass eine spätere Demontage der Welle oder ein Austausch des Rollladenpanzers nicht oder nur erschwert möglich ist, siehe hierzur die DE 20 2008 000 251 U1 . Da je nachdem, welchen Durchmesser der aufgewickelte Rollladenpanzer besitzt, Rollladenkästen mit verschiedenen Höhen und Tiefen ausgewählt werden müssen, sind auch für jede Höhen- oder Tiefenstufung in einem Rollladenkastensystem separate Aussteifungselemente erforderlich.Conventionally bow-shaped static brackets made of metal are used as stiffening elements, which are bolted firmly in the shutter box to the frame, so that a subsequent disassembly of the shaft or replacement of the roller shutter is not or only possible is difficult, see herezur DE 20 2008 000 251 U1 , Since, depending on the diameter of the wound roller shutter shell has to be selected roller shutter boxes with different heights and depths, separate stiffening elements are required for each height or depth grading in a roller shutter box system.

Die Aufgabe der vorliegenden Erfindung besteht somit darin, ein verbessertes Aussteifungselement für Rollladenkästen anzugeben, das leicht für verschiedene Höhen und Tiefen des Rollladenkastens anpassbar ist und das einen leichten Zugriff auf den Rollladenpanzer im Revisionsfall ermöglicht.The object of the present invention is therefore to provide an improved stiffening element for roller shutter boxes, which is easily adaptable to different heights and depths of the shutter box and which allows easy access to the roller shutter in case of revision.

Erfindungsgemäß wird diese Aufgabe durch ein Aussteifungselement mit den Merkmalen des Schutzanspruchs 1 oder des Schutzanspruchs 2 gelöst, welche Varianten sich lediglich in der gegensätzlichen Anordnung von Vorsprüngen und dazu kompatiblen Ausnehmungen voneinander unterscheiden.According to the invention, this object is achieved by a stiffening element with the features of the protection claim 1 or the protection claim 2, which variants differ from each other only in the opposite arrangement of projections and compatible recesses.

Ein Aussteifungselement gemäß der vorliegenden Erfindung ist im Wesentlichen dreiteilig ausgebildet und umfasst wenigstens:

  • ein Bodenanschlusselement, das eine Reihe von Befestigungsbohrungen und/oder ein Langloch enthält, und eine rechtwinklig angeordnete Bodenbefestigungslasche aufweist;
  • ein Deckenanschlusselement, das ebenfalls eine Reihe von Befestigungsbohrungen oder ein Langloch enthält und eine rechtwinklig angeordnete Deckenbefestigungslasche aufweist,
  • sowie ein Verbindungselement.
A stiffening element according to the present invention is essentially formed in three parts and comprises at least:
  • a bottom connection element including a series of mounting holes and / or a slot, and a bottom attachment plate arranged at right angles;
  • a ceiling connection element which also contains a series of fixing holes or a slot and has a ceiling fixing plate arranged at right angles,
  • and a connecting element.

Dabei ist vorgesehen, dass das Verbindungselement mit dem Bodenanschlusselement und mit dem Deckenanschlusselement zum einen jeweils über ein Verbindungsmittel verbunden ist, das in eine der Befestigungsbohrungen oder in das Langloch eingesetzt ist, wobei zum anderen Vorsprünge der Anschlusselemente in Ausnehmungen des Verbindungselements eingreifen. Das Verbindungsmittel, ist insbesondere eine Verbindungsschraube.It is provided that the connecting element is connected to the bottom connection element and the ceiling connection element on the one hand via a connecting means which is inserted into one of the mounting holes or in the slot, on the other hand, engage projections of the connection elements in recesses of the connecting element. The connecting means, in particular a connecting screw.

An den Verbindungsstellen zwischen dem Deckenanschlusselement und dem Verbindungselement einerseits und zwischen dem Bodenanschlusselement und dem Verbindungselement andererseits werden jeweils zwei Befestigungspunkte ausgebildet, so dass an beiden Verbindungsstellen in der im Einbauzustand gegebenen Belastungsrichtung des Aussteifungselements - also quer zur Längserstreckung des Rollladenkastens - Drehmomente übertragen werden können. Der erste Befestigungspunkt wird durch eine Verschraubung gebildet, die in einem Langloch geführt ist bzw. in einer Bohrung aus der Reihe von Befestigungsbohrungen, so dass sich eine Verstellmöglichkeit ergibt, um das Aussteifungselement an Rollladenkästen mit unterschiedlichen Querschnitt anzupassen.At the connection points between the ceiling connection element and the connection element on the one hand and between the bottom connection element and the connection element on the other two attachment points are formed so that at both connection points in the installed state loading direction of the stiffening element - ie transverse to the longitudinal extent of the shutter box - torques can be transmitted. The first attachment point is formed by a screw which is guided in a slot or in a bore of the row of mounting holes, so that there is an adjustment to adapt the stiffening element to shutter boxes with different cross-section.

Zugleich greifen Vorsprünge in kompatible Ausnehmungen ein, so dass mit Abstand zu der Verschraubung als erster Verbindungsstelle eine zweite formschlüssige Verbindung erreicht wird. Die Vorsprünge bzw. Ausnehmungen sind in einer bestimmten Anordnung zueinander vorgegeben, durch welche das Aussteifungselement an die üblichen Bautiefen und Bauhöhen eines Rollladenkastens leicht angepasst werden kann. Dabei erstreckt sich der Verlauf der zweiten Befestigungspunkte, gebildet jeweils aus Vorsprung und Ausnehmungen, parallel zur Mittelachse des Langlaufs bzw. der Reihe von Befestigungsbohrungen. Vorsprünge und Ausnehmungen können punktuell aufeinander abgestimmt sein. Die Ausnehmungen zur Aufnahme der Vorsprünge könne aber auch langlochförmig ausgebildet sein.At the same time, projections engage in compatible recesses so that a second positive connection is achieved at a distance from the screw connection as the first connection point. The projections or recesses are predetermined in a particular arrangement to each other, by which the stiffening element can be easily adapted to the usual depths and heights of a roller shutter box. In this case, the course of the second attachment points, each formed by a projection and recesses, extends parallel to the central axis of the cross-country skiing or the row of fastening bores. Projections and recesses can be at points be coordinated. The recesses for receiving the projections could also be formed slot-shaped.

Während punktuell platzierte Ausnehmungen den Vorteil haben, exakt an ein bestimmtes Rollladenkastensystem eines Herstellers angepasst zu sein, hat eine Ausführungsform, bei der sowohl die Befestigungsschraube wie auch die Vorsprünge in Langlöchern geführt sind, den Vorteil, individuell in der Länge verstellt werden zu können. Die Verwendung eines Langlochs ist vor allem deshalb vorteilhaft, weil dadurch der Abstand der Elemente zueinander während der Montage verkürzt werden kann. Sind alle Elemente lagerichtig positioniert, wird die Konfiguration so wie möglich auseinandergezogen, damit sich alle Einzelelemente spielfrei an die Innenflächen im Rollladenkasten anlegen. Somit müssen die Einzelelemente für die Positionierung bei der Montage nicht vollständig voneinander gelöst werden. Ein leichtes Lösen der Verbindungsmittel, insbesondere Verbindungsschrauben, reicht. Man erhält so zur Montage eine gute verformbare Gliederkette aus drei Einzelelementen, die gut handhabbar ist. Nach der Positionierung und dem festen Anziehen der Verbindungsschrauben erhält man dann ein statisch belastbares Element.While selectively placed recesses have the advantage of being exactly adapted to a particular roller shutter system of a manufacturer, an embodiment in which both the fastening screw and the projections are guided in slots, the advantage of being able to be adjusted individually in length. The use of a slot is especially advantageous because it allows the distance between the elements to each other during assembly can be shortened. If all elements are positioned correctly, the configuration is pulled apart as far as possible so that all individual elements rest against the inner surfaces in the roller shutter box without play. Thus, the individual elements for positioning during assembly need not be completely detached from each other. A slight release of the connecting means, in particular connecting screws, is sufficient. This gives the assembly a good deformable link chain of three individual elements, which is easy to handle. After positioning and tightening the connecting screws then you get a statically resilient element.

In jedem Fall werden alle drei wesentlichen Elemente des erfindungsgemäßen Aussteifungselements aufgrund der doppelten Verbindung stets in einer bestimmten Winkellage zueinander montiert, so dass das montierte Aussteifungselement eine vorzugsweise L-förmige oder U-förmige Konfiguration besitzt, welche gut geeignet ist, den verbleibenden Hohlraum im Rollladenkasten zwischen den Seitenwänden und dem aufgewickelten Rollladenpanzer auszufüllen. Die Form des Aussteifungselements ist so ausgeführt, dass dieses nur im Bereich der Verschraubung an den Profilblenden anliegt und somit keine Wärmebrücken bildet.In any case, all three essential elements of the stiffening element according to the invention are always mounted in a certain angular position to each other due to the double connection, so that the mounted stiffening element has a preferably L-shaped or U-shaped configuration, which is well suited to the remaining cavity in the shutter box between the side walls and the wound roller shutter. The shape of the stiffening element is designed so that this rests only in the region of the screw to the profile panels and thus forms no thermal bridges.

Unter Rollladenkästen werden erfindungsgemäß auch diejenigen Kästen verstanden, die zur Aufnahme anderer Fenstervorhänge dienen, wie beispielsweise von sogenannten Raffstores, also aus verstellbaren Lamellen gebildeten Außenjalousien, oder von Mückenschutzgittern.Under shutter boxes according to the invention, those boxes are understood to serve to accommodate other window curtains, such as so-called external blinds, so formed from adjustable slats outer blinds, or mosquito screens.

Das erfindungsgemäße Aussteifungselement kann bereits fertig montiert und auf die Größe des Rollladenkastens angepasst ausgeliefert werden. Es ist jedoch auch möglich, durch Lösen bzw. Versetzen der Befestigungsschrauben andere Größen am Aussteifungselement einzustellen, so dass das erfindungsgemäße Aussteifungselement universell für alle Rollladenkästen eines Herstellers verwendet werden kann. In einem Rollladenkastensystem werden somit weniger Teile benötigt, die hergestellt und vorrätig gehalten werden müssen. Der Vorteil der lösbaren Verbindung der drei wesentlichen Elemente liegt zudem darin, dass es bei größeren Bauhöhen des Rollladenkastens unter Umständen schon ausreichend ist, nur das Verbindungselement abzuschrauben, um die Welle des Rollladens zwischen Boden- und Deckenanschlusselement hindurch nach hinten aus dem Rollladenkasten heraus ziehen zu könnenThe stiffening element according to the invention can already be completely assembled and delivered adapted to the size of the roller shutter box. However, it is also possible to adjust other sizes on the stiffening element by loosening or displacing the fastening screws, so that the stiffening element according to the invention can be universally used for all roller shutter cases of a manufacturer. In a roller shutter box system thus fewer parts are needed, which must be manufactured and stocked. The advantage of the detachable connection of the three essential elements is also that it is already sufficient for larger heights of the roller shutter box, unscrew only the fastener to pull the shaft of the shutter between the floor and ceiling connection element to the rear out of the shutter box can

Besonders bevorzugt ist vorgesehen, dass die Bodenbefestigungslasche und die Deckenbefestigungslasche parallel zueinander angeordnet sind, und dass die Bodenbefestigungslasche und die Deckenbefestigungslaschen jeweils an der gleichen Seitenkante wenigstens eine Aufnahmenut für eine Befestigungsschraube besitzen. Damit ist eine besonders einfache Montage möglich, indem zunächst nur die vorgesehenen Befestigungsschrauben am Boden- bzw. Deckenprofil eingesetzt werden: Hierzu werden zunächst die Dämmelemente aus dem Rollladenkasten entnommen, so dass die vorgesehenen Befestigungsstellen leicht zugänglich sind. Die Befestigungsstellen können dabei im Abrollprofil, das auf dem Blendrahmen aufgesetzt ist, vorgefertigt werden, beispielsweise durch in einem bestimmten Abstand eingesetzte Gewindehülsen. Damit ist es nicht mehr notwendig, mit Bohrmaschinen oder dergleichen innerhalb des Rollladenkastens zu arbeiten, um die Befestigungspunkte vorzubereiten. Anschließend wird das fertig vorbereitete Aussteifungselement mit seinen Befestigungslaschen von der Seite her unter die ortsfesten Schraubenköpfe geschoben. Es müssen dann nur noch die Schrauben angezogen werden, um das Aussteifungselement fest zu montieren. Abschließend werden die Dämmelemente wieder eingesetzt und der Rollladenkasten wird verschlossen. Im Revisionsfall erfolgt die Demontage in umgekehrter Reihenfolge. Auch hierbei ist vorteilhaft, dass die rollladenkastenseitigen Befestigungsschrauben nur gelockert, aber nicht vollständig entfernt werden müssen, so dass die erneute Montage später einfacher durchführbar ist.It is particularly preferably provided that the bottom attachment tab and the ceiling mounting tab are arranged parallel to each other, and that the bottom mounting tab and the ceiling mounting tabs each have at least one receiving groove for a fastening screw on the same side edge. For a particularly simple installation is possible by initially only the proposed mounting screws are used on the floor or ceiling profile: For this purpose, the first insulation elements are removed from the shutter box, so that the intended attachment points are easily accessible. The attachment points can be prefabricated in Abrollprofil, which is placed on the frame, for example, by threaded at a certain distance threaded sleeves. Thus, it is no longer necessary to work with drills or the like within the roller shutter box to prepare the attachment points. Subsequently, the ready-prepared stiffening element is pushed with its fastening tabs from the side under the stationary screw heads. Then only the screws have to be tightened in order to firmly mount the stiffening element. Finally, the insulation elements are used again and the Roller shutter box is closed. In case of revision, dismantling takes place in reverse order. Here, too, is advantageous that the shutter box side fixing screws only loosened, but not completely removed, so that the re-assembly is easier to carry out later.

Vorgesehen sein kann auch, dass im Abrollprofil Gewindebolzen eingesetzt sind, auf denen eine Gewindemutter montiert wird.It can also be provided that in the rolling profile threaded bolts are used, on which a threaded nut is mounted.

Figur 1 zeigte ein Aussteifungselement 10, das aus einem Bodenanschlusselement 11, einem Verbindungselement 12 und einem Deckenanschlusselement 13 besteht, welche drehmomenensteif miteinander verbunden werden. Bevor auf die Ausbildung der Elemente 11, 12, 13 im Einzelnen eingegangen wird, sei zunächst die Lage des Aussteifungselements 10 innerhalb eines Rollladenkastens 100 erläutert, welche in Figur 3 dargestellt ist: FIG. 1 showed a stiffening element 10, which consists of a bottom connection element 11, a connecting element 12 and a ceiling connection element 13, which are torsionally rigidly connected to each other. Before discussing the formation of the elements 11, 12, 13 in detail, the position of the stiffening element 10 within a roller shutter box 100 is first explained, which in FIG. 3 is shown:

Der Rollladenkasten 100 besitzt eine zur Gebäudeaußenseite gewandte Seitenwand 21 sowie eine zur Gebäudeinnenseite gewandte Seitenwand 23. Nach oben hin ist der Rollladenkasten durch ein Deckelelement 22 abgeschlossen, das über ein Verbindungsprofil 40 oder Verbindungselement mit einer Gebäudedecke zu verbinden ist. Unten ist ein Bodenelement 24 vorgesehen, das alternativ oder zusätzlich zur Seitenwand 23 als Revisionsöffnung benutzt werden kann.The roller shutter box 100 has a side facing the building exterior side wall 21 and a side facing the building side wall 23. At the top of the shutter box is closed by a cover member 22 having a connection profile 40 or connecting element with is to connect a building ceiling. Below a bottom element 24 is provided, which can be used as an alternative or in addition to the side wall 23 as a revision opening.

Auf einem Blendrahmen 50 ist ein zweiteiliges Abrollprofil montiert. Das untere Abrollprofil 51 besitzt an der zum abgewickelten Teil 32 des Rollladenpanzers 30 gewandten Seite eine Rundung und stellt Rastaufnahmen für das obere Abrollprofil 52 bereit.On a frame 50, a two-piece rolling profile is mounted. The lower Abrollprofil 51 has on the side of the unwound part 32 of the roller shutter 30 side facing a rounding and provides locking receptacles for the upper Abrollprofil 52 ready.

Der zwischen dem unteren und dem oberen Abrollprofil 51, 52 gebildete Hohlraum kann zur Aufnahme einer Befestigungsplatte benutzt werden, welche eine Gewindebohrung oder einen Gewindebolzen enthält, mittels derer das Bodenanschlusselement 11 befestigt werden kann.The cavity formed between the lower and the upper Abrollprofil 51, 52 can be used to receive a mounting plate which includes a threaded bore or a threaded bolt, by means of which the bottom connection element 11 can be attached.

Ausgehend von dem Befestigungspunkt am Abrollprofil 52 erstreckt sich das Bodenanschlusselement 11 zunächst parallel zur Befestigungsebene, also parallel zum Bodenelement 25 eines Rollladenkastens 100. Damit besitzt das Bodenanschlusselement 11 in dem unmittelbar unter dem Zentrum des Rollladenpanzers 30 liegenden Bereich eine geringere Profilhöhe. Zur anderen Seite hin ist ein abgeschrägter Bereich vorgesehen, der in dem freien Eckbereich des Rollladenkastens 100 positioniert ist.Starting from the attachment point on the roll-off profile 52, the base connection element 11 initially extends parallel to the fastening plane, ie parallel to the floor element 25 of a roller shutter box 100. Thus, the floor connection element 11 has a lower profile height in the area located directly below the center of the roller shutter curtain 30. On the other side, a chamfered area is provided, which is positioned in the free corner area of the roller shutter box 100.

Das Verbindungselement 12 erstreckt sich von dem unteren Eckenbereich aus überwiegend vertikal, parallel zur gebäudeinnenseitigen Seitenwand 23 des Rollladenkastens 100 bis in den oberen Eckenbereich. Dort ist das Deckenanschlusselement 13 vorgesehen, das ebenfalls eine Befestigungslasche aufweist. Wie Figur 3 anschaulich zeigt, ist das Aussteifungselement 10 an seinen beiden Enden an den statisch relevanten Punkten des Rollladenkastens 100 befestigt und leitet aufgrund seiner auch in den Eckbereichen momentensteifen Ausbildung die von der Decke auf den Blendrahmen 50 wirkenden Stützkräfte um den aufgewickelten Rollladenpanzer 30 herum.The connecting element 12 extends from the lower corner region of predominantly vertically, parallel to the building inside side wall 23 of the shutter box 100 to the upper corner area. There, the ceiling connection element 13 is provided, which also has a fastening tab. As FIG. 3 clearly shows, the stiffening element 10 is attached at its two ends to the statically relevant points of the roller shutter box 100 and directs due to its torque-training in the corner areas the forces acting from the ceiling on the frame 50 supporting forces around the wound roller shutter 30 around.

Die genaue Ausbildung des Aussteifungselements 10 wird nun wiederum unter Bezug auf Figur 1 erläutert:The exact formation of the stiffening element 10 will now turn with reference to FIG. 1 explains:

Das Bodenanschlusselement 11 besitzt an der rechtwinklig angestellten Befestigungslasche 11.1 wenigstens eine Befestigungsnut, im dargestellten Ausführungsbeispiel zwei Befestigungsnuten 11.3, die an einer Seitenkante der Befestigungslasche 11.1 enden, um ein seitliches Einschieben unter einem Schraubenkopf oder unter eine Mutter zu ermöglichen. Am entgegen gesetzten Ende besitzt das Bodenanschlusselement 11 neben einer Langlochaufnahme 11.2 einen Vorsprung 11.4, der im Ausführungsbeispiel als abgekantete Blechlasche ausgebildet ist.The bottom connection element 11 has at the right angle angeigt fastening tab 11.1 at least one fastening groove, in the illustrated embodiment, two fastening grooves 11.3, which terminate at a side edge of the fastening tab 11.1 to allow lateral insertion under a screw head or under a nut. At the opposite end of the bottom terminal 11 has next to a slot 11.2 a projection 11.4, which is formed in the embodiment as a folded sheet metal tab.

Am Verbindungselement 12 ist im unteren Bereich eine Gewindebohrung 12.4 vorgesehen, die eine durch das Langloch 11.2 geführte Schraube 14 aufnimmt. Weiterhin besitzt das Verbindungselement 12 mehrere schlitzförmige Ausnehmungen 12.2, in welche der stegförmige Vorsprung 11.4 eingreifen kann. Oben ist eine weitere Gewindebohrung für eine weitere Schraube 15 vorgesehen. Anstelle der Gewindebohrungen 12.3, 12.4 kann auch jeweils eine Mutter aufgeschweißt sein. Das in das Verbindungselement 12 integrierte oder damit verbundene Innengewinde hat in jedem Fall den Vorteil, dass die Demontage und Montage des Verbindungselement 12 vereinfacht ist, wenn nur die Schrauben 14, 15 gelöst bzw. eingesetzt und angezogen werden müssen, und nicht noch jeweils eine separate Mutter positioniert und festgehalten werden muss, wozu außerdem noch ein zweites Werkzeug erforderlich wäre.On the connecting element 12, a threaded bore 12.4 is provided in the lower region, which receives a guided through the slot 11.2 screw 14. Furthermore, the connecting element 12 has a plurality of slot-shaped recesses 12.2, in which the web-shaped projection can engage 11.4. Above another threaded hole for another screw 15 is provided. Instead of the threaded holes 12.3, 12.4 can also be welded in each case a nut. The internal thread integrated in or connected to the connecting element 12 always has the advantage that the disassembly and assembly of the connecting element 12 is simplified if only the screws 14, 15 have to be loosened or inserted and tightened, and not a separate one Mother must be positioned and held, what also a second tool would be required.

Die Schraube 15 ist durch ein Langloch 13.2 im Deckenanschlusselement 13 geführt und greift in die Gewindebohrung 12.3 ein. Am unteren Ende des Deckenanschlusselements 13 ist ein Vorsprung 13.4 abgekantet, der in eine der schlitzförmigen Ausnehmungen 12.1 im Verbindungselement 12 eingreift.The screw 15 is guided through a slot 13.2 in the ceiling connection element 13 and engages in the threaded bore 12.3. At the lower end of the ceiling connection element 13, a projection 13.4 is bent, which engages in one of the slot-shaped recesses 12.1 in the connecting element 12.

Das Deckenanschlusselement 13 wiederum besitzt Befestigungsnuten 13.3, die an einer Seitenkante der Befestigungslasche 13.1 enden, und zwar bevorzugt auf derselben Seite wie an der unteren Befestigungslasche 11.1. Figur 2a zeigt das Aussteifungselement 10 im montierten Zustand, wie er in der Einbausituation nach Figur 3 gezeigt ist. Die Befestigungsschrauben 14, 15 befinden sich an den jeweiligen Enden der Langlöcher 13.2, 11.2. Das Aussteifungselement 10 ist also auf seine maximale Höhe ausgezogen.The ceiling connection element 13 in turn has fastening grooves 13.3 which terminate at a side edge of the fastening tab 13.1, preferably on the same side as at the lower fastening tab 11.1. FIG. 2a shows the stiffening element 10 in the assembled state, as in the installation situation FIG. 3 is shown. The fastening screws 14, 15 are located at the respective ends of the elongated holes 13.2, 11.2. The stiffening element 10 is thus pulled out to its maximum height.

Die Konfiguration des Aussteifungselements 10 mit minimaler Höhe zeigt Figur 2b. Hier befinden sich die Befestigungsschrauben 14, 15 am jeweiligen anderen Ende der hier nicht sichtbaren Langlöcher, und die Vorsprünge 11.4,13.4 greifen in Ausnehmungen 12.1, 12.2 ein, welche in der Mitte des Verbindungselements 12 liegen.The configuration of the minimum height stiffener 10 is shown in FIG. 2b. Here are the mounting screws 14, 15 at the other end of the not visible here oblong holes, and the projections 11.4,13.4 engage in recesses 12.1, 12.2, which lie in the middle of the connecting element 12.

Die Figuren 4a, 4b zeigen ein leicht abgewandeltes Aussteifungselement 10' in einer Konfiguration für maximale Höhe. Das Deckenanschlusselement 13 und das Verbindungselement 12 sind wie bei der zuvor beschriebenen Ausführungsform des Aussteifungselements 10 ausgebildet. Unterschiedlich hingegen ist die Ausbildung des Bodenanschlusselementes 11': Bei dieser Ausführungsform ist kein langer bügelförmiger Abschnitt vorhanden, da das in einem Rollladenkasten aufgenommene Paket von Lamellen eines Raffstores nur Höhe, aber keine große Tiefe des Rollladenkastens benötigt, anders als bei einem aufgewickelten Rollladenpanzer.The FIGS. 4a . 4b show a slightly modified stiffener 10 'in a maximum height configuration. The ceiling connection element 13 and the connection element 12 are formed as in the previously described embodiment of the stiffening element 10. In contrast, the embodiment of the bottom connection element 11 ': In this embodiment, no long bow-shaped section is present, since the recorded in a roller shutter box package of slats of a Venetian blind only height, but no great depth of the shutter box needs, unlike a wound roller shutter.

Insbesondere ist, wie in den Figuren 4a und 4b erkennbar, das Bodenanschlusselement 11' identisch mit dem Deckenanschlusselement 13. Durch die Verwendung eines baugleichen Teiles kann für diesen Anwendungsfall ein Aussteifungselement 10` gebildet werden, ohne dass zusätzliche Bauteile erforderlich sind. Um das winkelförmige Deckenanschlusselement 13 als Bodenanschlusselement 11' verwenden zu können, wird dieses um 180° gewendet eingesetzt, wird also unten von einer anderen Seite an das Verbindungselement 12 angeschraubt als bei dem oberen Deckenanschlusselement 13. In Figur 4a liegt das Verbindungselement 12 entsprechend hinter dem Bodenanschlusselement 11'.In particular, as in the FIGS. 4a and 4b recognizable, the bottom connection element 11 'identical to the ceiling connection element 13. By using a structurally identical part can be formed for this application, a stiffening element 10`, without additional components are required. In order to use the angled ceiling connection element 13 as a floor connection element 11 ', this is used turned by 180 °, so it is screwed down from another side to the connecting element 12 as in the upper ceiling connection element 13. In FIG. 4a the connecting element 12 is located behind the bottom connection element 11 '.

Figur 4b zeigt das Aussteifungselement 10' von der Rückseite her und in einer anderen Konfiguration, welche für eine minimale Bauhöhe des Rollladenkastens vorgesehen ist. Hier weist die Bodenbefestigungslasche 11.1' auf den Betrachter zu, während bei dem Deckenanschlusselement 13 die Befestigungslasche 13.1 von der Bildebene nach hinten gerichtet ist. FIG. 4b shows the stiffening element 10 'from the rear and in another configuration, which is provided for a minimum height of the roller shutter box. Here, the bottom attachment tab 11.1 'toward the viewer, while in the ceiling connection element 13, the fastening tab 13.1 is directed from the image plane to the rear.
