Abstract

PCT No. PCT/AT94/00206 Sec. 371 Date Jun. 27, 1996 Sec. 102(e) Date Jun. 27, 1996 PCT Filed Dec. 29, 1994 PCT Pub. No. WO95/18285 PCT Pub. Date Jul. 6, 1995A roller shutter slat has hollow sectional slats (1) with a central part (1c), two edge parts (1a) and transverse grooves (1b) arranged therebetween for receiving bearing or adjusting links (3, 4). The edge parts (1a) and the central parts (1c) are spaced apart and interconnected by linking elements (5, 6, 40, 41) inserted into hollow chambers (26) of the hollow sectional slat (1). The cross-section of the linking elements (5, 6, 40, 41) is narrower than the cross-section of the hollow chambers (26) and the linking elements (5, 6, 40, 41) are linked to the hollow sectional slats (1) by tongue-and-groove joints (9, 10; 42, 43). Easy-to-produce grooves (1b) are thus created without weakening the roller shutter slat (1) in the area of the grooves (1b).

Description

Die Erfindung betrifft einen Rolladenstab, der als Hohlprofilstab ausgebildet ist und quer zu seiner Längserstreckung Nuten zur Aufnahme von Kettengliedern aufweist, wobei ein Verbindungselement zum Verbinden von zwei Teilen des Hohlprofilstabes in eine Hohlkammer dieser einsteckbar ist.The invention relates to a roller shutter rod, which is used as a hollow profile rod is formed and grooves transverse to its longitudinal extent for receiving chain links, wherein a connecting element for connecting two parts of the hollow profile rod it can be inserted into a hollow chamber.

Aus der WO 93/21417 und der EP-A-189 091 sind Rolladensysteme bekannt, bei welchen in den Rolladenstäben quer zur Längserstreckung der Stäbe Nuten oder Ausnehmungen angeordnet sind, um Freiräume zu schaffen, in denen Verstell- oder Tragekettenglieder Platz finden können. Diese Nuten werden z.B. durch Ausfräsen aus dem Rolladenstabprofil hergestellt. Bei diesem Aufbau sind zwar relativ wenige Bauteile erforderlich, jedoch ist das Herstellen dieser Nuten oder Ausnehmungen zeitaufwendig und teuer. Ein weiterer Nachteil ist, daß ein Konflikt dahingehend entsteht, daß der im Bereich der Nut oder Ausnehmung verbleibende Querschnitt des Rolladenstabes nicht zu schwach sein darf, damit der Rolladen eine ausreichende Festigkeit behält, das heißt, daß die Wandstärken des als Hohlprofil ausgeführten Rolladenstabes relativ groß sein müssen, was jedoch anderseits zu einem relativ hohen Gewicht des Rollladenstabes führt und seine Kosten erhöht, was aber nicht in erwünschtem Maße zu einer Erhöhung der Steifigkeit des Profiles führt.From WO 93/21417 and EP-A-189 091 are roller shutter systems known, in which in the shutter bars transverse to the longitudinal extent the rods are arranged in grooves or recesses, to create free spaces in which adjustment or carrying chain links Can find space. These grooves are e.g. by Milled out of the roller shutter slat profile. With this Construction requires relatively few components, however the production of these grooves or recesses is time consuming and expensive. Another disadvantage is that there is a conflict in that arises that in the area of the groove or recess remaining cross-section of the roller shutter rod does not close may be weak so that the roller shutter has sufficient strength retains, that is, the wall thicknesses of the as a hollow profile roller shutter rod must be relatively large, which, on the other hand, leads to a relatively high weight of the roller shutter rod leads and increases its costs, but not in desired degree to increase the stiffness of the profile leads.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Rolladen zur Verfügung zu stellen, der einerseits kostengünstig hergestellt werden kann, der aber anderseits eine ausreichend hohe Festigkeit aufweist, ohne unnötig schwer zu sein.The invention is therefore based on the object of a roller shutter to provide the one hand, manufactured inexpensively can be, but on the other hand a sufficiently high Has strength without being unnecessarily heavy.

Gelöst wird diese Aufgabe bei einem gattungsgemäßen Rolladen dadurch, daß die zwei Teile des Hohlprofilstabes voneinander beabstandet sind und mit dem Verbindungselement die Nut begrenzen.This task is solved with a generic roller shutter in that the two parts of the hollow profile rod from each other are spaced and limit the groove with the connecting element.

Aus der EP-A-189 091 ist es zwar bekannt, Teile von Rolladenstäben über in Hohlprofilkammern eingeschobene Zapfenteile zu verbinden. Diese Zapfenteile kommen jedoch nicht an der Stelle zum Einsatz, wo Trage- oder Verstellkettenglieder im Rolladenstab aufgenommen werden sollen.From EP-A-189 091 it is known to parts of roller shutter bars via pin parts inserted in hollow profile chambers connect. However, these pin parts do not come in place for use where there are support or adjustable chain links in the roller shutter slat should be included.

Die vorgenannten Probleme werden durch das erfindungsgemäße Verbindungselement auf einfache Weise gelöst, da im Bereich von Trage-oder Verstellkettengliedern der Rolladenstab selbst nicht geschwächt sondern durch ein stabiles Verbindungselement ersetzt ist.The aforementioned problems are solved by the invention Connection element solved in a simple way, because in the area of carrying or adjusting chain links the roller shutter bar itself not weakened but by a stable connecting element is replaced.

Bei der Herstellung des Rolladens ergibt sich auch der Vorteil, daß die einzelnen Teile, das heißt die Rolladenstäbe, die Verbindungselemente, die Trage- und die Verstellkettenglieder durch gerade Schnitte und somit im Paket abgeschnitten werden können, wodurch nicht nur der Maschinenpark zur Herstellung des Rolladens technisch weniger aufwendig und somit billiger sein kann, sondern auch die Bearbeitungszeiten verkürzt werden können. Die Rolladenstäbe und die Verbindungselemente müssen nach dem geraden Abschneiden nur mehr ineinandergeschoben und z.B. durch Kerbpressung oder Klebstoff fest miteinander verbunden werden.The manufacture of the roller shutter also has the advantage that the individual parts, i.e. the roller shutter slats, the connecting elements, the carrying and the adjustment chain links by straight cuts and thus cut off in the package can be, which not only the machinery for manufacturing the roller shutter is technically less complex and therefore can be cheaper, but also reduces processing times can be. The roller shutter slats and the connecting elements just have to be pushed into each other after the straight cut and e.g. by notching or adhesive be connected to each other.

Direkt an der Verbindungsstelle, wo z.B. ein Zug- oder Verstellkettenglied aufgenommen werden soll, ist der Rolladenstab zwar teilweise wie ein Vollstab, sofern das Verbindungselement als Vollstab und nicht ebenfalls als Hohlprofilstab ausgeführt ist, und somit etwas schwerer, dafür weist der Rolladenstab aber in diesem Bereich, wo er bei den bekannten Ausführungsformen geschwächt ist, eine besonders hohe Festigkeit auf. Da Rolläden jedoch üblicherweise über eine größere Breite verfügen und der übrige Teil des Rolladenstabes besonders leicht und dünnwandig ausgeführt sein kann, wird man durch die Erfindung wesentlich an Gewicht einsparen können, ohne daß der Rolladenstab an Festigkeit verliert.Directly at the connection point, where e.g. a pull or adjustment chain link The shutter rod is to be included partly like a solid rod, provided that the connecting element as a solid rod and not also as a hollow profile rod is, and therefore somewhat heavier, the shutter rod has but in this area where it is in the known embodiments is weakened, a particularly high strength. There However, roller shutters usually have a larger width and the rest of the roller shutter rod is particularly light and can be made thin-walled, one becomes by the invention can save significantly in weight without the Roller shutter bar loses strength.

Wenn das Verbindungselement die Hohlkammer im Hohlprofilstab im wesentlichen völlig ausfüllt, kann dies das Problem aufwerfen, daß die Wandstärke der Zug- oder Verstellkettenglieder höchstens gleich groß wie die Wandstärke der Rolladenstäbe sein kann, so daß bei geringen Wandstärken der Rolladenstäbe die Trage- oder Verstellkettenglieder nur schwach ausgeführt sein können, so daß sich bei den Trage- und Verstellkettengliedern in einigen Fällen Festigkeitsprobleme ergeben könnten.If the connecting element the hollow chamber in the hollow profile rod essentially completely filling in, this can pose the problem that the wall thickness of the tension or adjustment chain links at most the same size as the wall thickness of the roller shutter slats can be so that with small wall thicknesses of the shutter bars the carrying or adjustment chain links are weak can be, so that the support and adjustment chain links strength problems in some cases.

Eine bevorzugte Weiterbildung der Erfindung ist daher dadurch gekennzeichnet, daß der Querschnitt des Verbindungsteiles schmäler ist als der Querschnitt der Hohlkammer und daß der Verbindungsteil über eine Nut-Feder-Verbindung mit den Hohlprofilstäben verbunden ist.A preferred development of the invention is therefore characterized in that the cross section of the connecting part is narrower than the cross section of the hollow chamber and that the Connection part via a tongue and groove connection with the hollow profile bars connected is.

Da das Verbindungselement in seinem Querschnitt schmäler als der Querschnitt der Hohlkammer ist, in die es eingesteckt ist, können die das Verbindungselement überlappenden Trage- oder Verstellkettenglieder eine größere Wandstärke als der Rollladenstab selbst aufweisen, ohne daß es zu einer Schwächung des Rolladenstabes in diesem Bereich kommt.Since the connecting element is narrower in cross section than is the cross section of the hollow chamber into which it is inserted, can the wearing or overlapping the connecting element Adjustable chain links have a greater wall thickness than the roller shutter slat have self without causing any weakening the roller shutter rod comes in this area.

Die feste Verbindung zwischen dem Einschubelement und dem Rolladenstab wiederum wird durch eine profilartige, formschlüssige Verbindung zwischen dem Verbindungselement und dem Rolladenstab hergestellt, so daß das Verbindungselement im Rolladenstab fest aufgenommen ist, obwohl sein Querschnitt schmäler als der Hohlkammerquerschnitt des Rolladenstabes ist, in dem er aufgenommen ist.The fixed connection between the insert element and the Roller shutter bar in turn is made by a profile-like, form-fitting Connection between the connecting element and the Roller shutter rod made so that the connecting element in Roller shutter bar is firmly received, although its cross section is narrower than the hollow section of the roller shutter slat, in which he is included.

Das Verstellkettenglied 3 ist über einen Bolzen 12 (siehe auch Fig. 4 und 5) mit den Teilen 1a, 1c des Rolladenstabes 1 verbunden. Die gelenkige Verbindung der Verstellkettenglieder 3 untereinander erfolgt über Ansätze 19 mit Langlochaugen, die am unteren Ende der Verstellkettenglieder 3 angebracht sind, und die in Ausnehmungen 18 zwischen Stegen 17 am oberen Ende der Verstellkettenglieder 3 eingreifen und mit diesen über Gelenkbolzen 11 verbunden sind.3 is a top view of one end of a roller shutter slat shown in the assembled state. Fig. 3 shows that between the parts 1a and 1c of the roller shutter bar 1 an adjustment chain link 3 is included. The adjustment chain link 3 is with a bolt 12 (see also Fig. 4 and 5) Parts 1a, 1c of the roller shutter rod 1 connected.

Aufgrund dieser besonderen Anordnung kann, wie in Fig. 4 und 5 dargestellt ist, das Verstellkettenglied 3 z.B. eine doppelt so große Wandstärke wie der Hohlprofilstab 1 aufweisen, wodurch dessen Festigkeit gegenüber einer Ausführungsform wesentlich erhöht ist, bei der das Verbindungselement die Hohlkammer 26 im Rolladenstab 1 vollständig ausfüllt, wodurch die Wandstärke des Verstellkettengliedes 3 dann nur die Wandstärke des Rolladenstabes 1 aufweisen könnte. Durch die profilartige, formschlüssige Verbindung des Verbindungselementes 5 mit dem Rolladenstab 1 in Form von Nuten 10 und Stegen 9 wiederum ist eine sehr feste Verbindung zwischen dem Verbindungselement 5 und dem Hohlprofilstab 1 gewährleistet, so daß insgesamt eine gegenüber dem Stand der Technik wesentlich einfacher herzustellende und dennoch tragfähigere Verbindung gegeben ist.Such as. 5 and 10 can be seen, the shutter rod has 1 a hollow chamber 26 in which the connecting element 5 is recorded. For a firm, positive connection of the Connecting element 5 with the roller shutter rod 1 have the front wall 51 and the rear wall 52 on the inner surfaces 27, 28 dovetail-shaped webs 9 on the corresponding Grooves 10 (Fig. 9) cooperate on the inside, i.e. the side of the connecting element facing the building interior 5 are arranged. The opposite outside 30 the connecting element 5 is smooth and the connecting element 5 lies with this outside only on the free End faces of the webs 9. This makes the outside 30 of the connecting element 5 by approximately twice the wall thickness 51 of the roller shutter rod 1 from the outer surface 31 of the latter spaced and the cross section of the connecting element 5 narrower than the hollow chamber cross section 26 of the roller shutter slat 1. Due to this special arrangement, as in FIG. 4 and 5, the chain link 3 e.g. a have twice the wall thickness as the hollow section rod 1, making it firm compared to one embodiment is significantly increased, in which the connecting element Hollow chamber 26 in the roller shutter bar 1 completely fills, whereby the wall thickness of the adjustment chain link 3 then only the wall thickness of the roller shutter bar 1 could have. Due to the profile-like, positive connection of the connecting element 5 with the roller shutter rod 1 in the form of grooves 10 and webs 9 again there is a very firm connection between the connecting element 5 and the hollow section rod 1 ensures that overall one essential compared to the prior art Connection that is easier to manufacture and yet more stable given is.

    In Fig. 4 und 5 ist weiters dargestellt, daß der Verblendungsteil 7 ebenfalls über eine Nut-Steg-Verbindung 9, 10 am Verbindungselement 5 befestigt ist.4 and 5 it is further shown that the facing part 7 also via a groove-web connection 9, 10 on the connecting element 5 is attached.

    In den Fig. 6 und 7 ist ein Querschnitt durch einen Rolladenstab im Bereich einer Mitteltragekette dargestellt, die z.B. bei besonders breiten Rolläden zum Einsatz kommen kann und z.B. in der Mitte des in Fig. 1 dargestellten Mittelteiles 1c des Rolladenstabes 1 angeordnet sein kann. Die Mitteltragekette besteht aus Kettengliedern 4, die an der Rückseite des Rolladenstabes 1 in einer Ausnehmung entsprechend den Ausnehmungen 1b angeordnet sind.6 and 7 is a cross section through a roller shutter slat shown in the area of a middle carrying chain, e.g. can be used with particularly wide shutters and e.g. in the middle of the central part 1c shown in FIG. 1 the roller shutter rod 1 can be arranged. The middle carrier chain consists of chain links 4, which are at the back of the Roller shutter bar 1 in a recess corresponding to the recesses 1b are arranged.

    Das Verbindungselement 6 ist in diesem Fall so gestaltet, daß die Rückseite 32 glatt und die Vorderseite 33 mit Nuten 10 ausgestattet und über die schwalbenschwanzförmigen Stege 9 mit dem Hohlprofilstab 1 verbunden ist (siehe auch Fig. 8).The connecting element 6 is designed in this case so that the back 32 smooth and the front 33 with grooves 10 equipped and with the dovetail-shaped webs 9 with the hollow section rod 1 is connected (see also Fig. 8).

    Das Mitteltragekettenglied 4 weist ebenso wie das Tragekettenglied 2 an seinem unteren Ende einen Vorsprung 22 mit einem Langlochauge und an seinem oberen Ende eine Ausnehmung 20 mit zwei Seitenstegen 21 auf, in welcher der Vorsprung 22 des benachbarten Mitteltragekettengliedes 4 aufgenommen und über einen Bolzen 34 gelenkig festgelegt ist.The middle support chain link 4 has the same as the support chain link 2 at its lower end a projection 22 with a Slotted eye and a recess 20 at its upper end two side webs 21, in which the projection 22 of the adjacent middle carrier chain link 4 added and over a bolt 34 is articulated.

    Damit die Außenfläche 31 des Rolladenstabes auch im Bereich der Mitteltragekette im wesentlichen glatt ausgebildet ist, ist ein Verblendungsteil 8 vorgesehen, der von außen auf das Verbindungselement 6 aufgesetzt und über Stege 9 mit den Nuten 10 des Verbindungselementes verbunden ist.So that the outer surface 31 of the roller shutter rod also in the area the middle carrying chain is essentially smooth, a facing part 8 is provided, which from the outside on the Connection element 6 placed and over webs 9 with the grooves 10 of the connecting element is connected.

    Wie insbesondere in Fig. 7 zu sehen ist, kann durch die erfindungsgemäße Ausbildung des Verbindungselementes 6 und des Hohlkammerprofiles des Rolladenstabes 1 auch der Querschnitt der Mitteltragekette 4 etwa doppelt so stark ausgeführt werden wie der Querschnitt der Rückwand 52 des Rolladenstabes 1, so daß ohne eine Schwächung des Rolladenstabes 1 in diesem Bereich eine sehr stabile Mitteltragekette 4 vorgesehen sein kann.As can be seen in particular in FIG. 7, the inventive method Formation of the connecting element 6 and the Hollow chamber profile of the roller shutter rod 1 also the cross section the middle carrier chain 4 are executed about twice as strong as the cross section of the rear wall 52 of the shutter bar 1, so that without weakening the roller shutter rod 1 in this area a very stable middle carrier chain 4 may be provided can.

    Wie in der Fig. 9 noch dargestellt ist, ist das untere Ende des Verbindungselementes 5 gerade abgeschnitten (Bezugszeichen 23), um die freie Verschwenkbarkeit des Fortsatzes 19 mit dem Langlochauge des Verstellkettengliedes 3 zu gewährleisten.As is shown in Fig. 9, is the lower end of the connecting element 5 just cut off (reference numerals 23) to the free pivotability of the extension 19 with the Ensure slotted eye of the adjustment chain link 3.

    In Verbindung mit den Fig. 11 bis 18 ist eine weitere Ausführungsform der Erfindung dargestellt, bei der die nut- und stegartige Verbindung zwischen Verbindungselement 40, 41 und Rolladenstab 1 im Bereich des oberen und unteren Längsrandes des Verbindungselementes 40, 41 angeordnet ist. Das Verbindungselement 40 weist an seinem oberen und unteren Längsrand einen Vorsprung bzw. einen Steg 42 auf, der in eine Nut 43 im Hohlprofilstab 1 eingreift und somit die Lage des Verbindungselementes 40, 41 im Hohlprofilstab 1 herstellt. Wie in Fig. 11 zu sehen ist, ist die Außenfläche 44 des Verbindungselementes 40 gegenüber der Außenfläche 45 des Rolladenstabes 1 wesentlich zurückversetzt, so daß das in Fig. 13 dargestellte Verstellkettenglied 3 eine wesentlich größere Wandstärke als der Hohlprofilstab 1 aufweisen kann.In connection with FIGS. 11 to 18 is a further embodiment shown the invention, in which the groove and web-like connection between connecting element 40, 41 and Roller shutter slat 1 in the area of the upper and lower longitudinal edge of the connecting element 40, 41 is arranged. The connecting element 40 has on its upper and lower longitudinal edge a projection or a web 42, which in a groove 43 in Hollow profile rod 1 engages and thus the position of the connecting element 40, 41 in the hollow section rod 1. As in Fig. 11 can be seen, the outer surface 44 of the connecting element 40 compared to the outer surface 45 of the roller shutter bar 1 essential set back so that the adjustment chain link shown in Fig. 13 3 a much larger wall thickness than that Can have hollow section rod 1.

    Entsprechendes gilt für das Verbindungselement 41, das im Bereich einer Mitteltragekette aus Kettengliedern 4 eingesetzt werden kann und dessen Rückwand 46 gegenüber der Rückwand 47 des Rolladenstabes 1 beträchtlich, d.h. um mehr als die Wandstärke 53 des Rolladenstabes 1, zurückversetzt ist, so daß auch die Wandstärke des Mitteltragekettengliedes 4 stärker als die Wandstärke des Rolladenstabes 1 sein kann.The same applies to the connecting element 41, which in the Area of a middle carrier chain made of chain links 4 used and the rear wall 46 of the rear wall 47 the roller shutter bar 1 considerably, i.e. by more than the wall thickness 53 of the roller shutter rod 1 is set back, so that also the wall thickness of the middle chain link 4 stronger than the wall thickness of the roller shutter rod 1 can be.

    Der Vorteil der in Verbindung mit den Fig. 11 bis 18 dargestellten Ausführungsform gegenüber der in den Fig. 1 bis 10 dargestellten Ausführungsform der Erfindung liegt darin, daß bei der Herstellung wesentlich geringere Fertigungstoleranzen einzuhalten sind. Dies und der Umstand, daß die Profilform der Verbindungselemente 40, 41 und des Hohlprofilstabes einfacher ist, führt dazu, daß auch die Werkzeuge zur Herstellung der in den Fig. 11, 12 und 15, 16 dargestellten Teile einfacher und somit billiger sind.The advantage of that shown in connection with FIGS. 11 to 18 Embodiment compared to that in FIGS. 1 to 10 illustrated embodiment of the invention is that significantly lower manufacturing tolerances during manufacture are to be observed. This and the fact that the profile shape of the Connecting elements 40, 41 and the hollow profile rod easier is leads to the fact that the tools for producing the in 11, 12 and 15, 16 parts shown simpler and are therefore cheaper.

    Um im Bereich der Verstellkettenglieder 3 die Rückwand der Verbindungselemente 40 abzudecken bzw. im Bereich einer Mitteltragekette die Vorderseite der Verbindungselemente 41 abzudecken, sind die in den Fig. 17 und 18 dargestellten Verblendungsteile 48 und 49 vorgesehen, die über Nuten 50 auf die Stege 42 der Verbindungselemente 40, 41 aufgesteckt werden können und somit dem Rolladenstab ein ebenmäßigeres Aussehen verleihen.To the rear wall of the adjustment chain links 3 Cover connecting elements 40 or in the area of a central carrier chain to cover the front of the connecting elements 41, are the facing parts shown in Figs. 17 and 18 48 and 49 are provided, which have grooves 50 on the Web 42 of the connecting elements 40, 41 are attached can and thus the shutter bar a more even appearance to lend.

    In der Hohlprofilkammer des in Fig. 12 dargestellten Tragekettengliedes 2 ist ein Verbindungselement 40 dargestellt, das nur in besonderen Fällen vorhanden ist, und zwar bei jenen Rolladenstäben, die im oberen Bereich eines Rolladens angeordnet sein können und die nicht aufklappbar ausgeführt sind. Bei diesen Rolladenstäben reicht das Verbindungselement 40 bis in das Tragekettenglied 2, um einen besonders stabilen Rolladenstab zu schaffen. Bei den anderen, aufklappbaren Rolladenstäben 1 ist in den Tragekettengliedern 2 kein Verbindungselement 40 aufgenommen. Das sobeben Gesagte trifft natürlich auch auf die in den Fig. 1 bis 10 dargestellte Ausführungsform zu.In the hollow profile chamber of the support chain link shown in Fig. 12 2 shows a connecting element 40 which is only present in special cases, namely those Roller shutter slats arranged in the upper area of a roller shutter can be and are not designed to be opened. At the connecting element 40 extends into these roller shutter bars the carrying chain link 2 to a particularly stable roller shutter bar to accomplish. With the other, foldable roller shutter slats 1 is not a connecting element in the carrying chain links 2 40 added. Of course, what has just been said also applies the embodiment shown in FIGS. 1 to 10 to.

    Es versteht sich, daß natürlich auch an den Verbindungselementen 40, 41 an deren Längsrändern Nuten und an den Hohlprofilstäben 1 anstatt der Nuten 43 Stege vorgesehen sein können, welche in die Nuten an den Verbindungselementen 40, 41 eingreifen und somit die formschlüssige Verbindung zwischen diesen Teilen herstellen.It goes without saying that of course also on the connecting elements 40, 41 grooves on the longitudinal edges and on the hollow profile bars 1 43 webs can be provided instead of the grooves, which engage in the grooves on the connecting elements 40, 41 and thus the positive connection between them Make parts.

    Es versteht sich weiters, daß die Form der Nuten und Stege nicht auf die in den Zeichnungen dargestellten Formen beschränkt sind, sondern eine beliebige Form aufweisen können, mit der eine profilartige Verbindung oder Verzahnung zwischen den Verbindungselementen und den Rolladenstäben zur Bildung einer formschlüssigen Verbindung zwischen diesen geschaffen wird, wobei es im wesentlichen unerheblich ist, ob nun die Nuten oder Ausnehmungen an den Rolladenstäben oder den Verbindungselementen angeordnet sind.It is further understood that the shape of the grooves and webs not limited to the shapes shown in the drawings are, but can have any shape, with a profile-like connection or toothing between the connecting elements and the shutter bars for formation a positive connection between them is, it is essentially irrelevant whether the Grooves or recesses on the roller shutter slats or the connecting elements are arranged.
