Description

Die Erfindung betrifft einen Rolladenstab, bestehend aus einem auf die Rolladenbreite abgelenkten Hohlkammerprofil mit zwei gleichsinnig gekrümmten, nach außen gewölbten Hauptabschnitten, die an ihren einen Enden erst aufeinander zu nach einwärts und dann gegeneinander nach auswärts unter anschließender Bildung eines doppelwandigen Hakens umgebogen sind, an dessen zum außenseitig konkaven Längsabschnitt hin umgebogenen Ende die Bandkanten einander umfassen, und die an ihren anderen Enden unter Ausbildung einer zum Profilende hin offenen und am Grund hablkreisförmig ausgerundeten Kammer zur Aufnahme des Hakens am nächsten Rolladenstab miteinander verbunden sind, wobei die im wesentlichen parallel zueinanderverlaufenden Seitenwände der Kammer durch scharfkantiges Rückbiegen der Profilhauptabschnitte gebildet sind und die Rückbiegung an dem einen Hauptabschnitt an dem in die Kammer hinein umgebogenen Ende eines doppelwandigen Gegenhakens für den Haken des nächsten Rolladenstabes gelegen ist.The invention relates to a roller shutter slat, consisting of a hollow chamber profile deflected to the roller shutter width with two coincident, outwardly curved main sections, which at one end are bent towards each other inwards and then outwards against each other with subsequent formation of a double-walled hook, on the other towards the outside concave longitudinal section bent end the band edges encompass each other, and the other ends are connected to form a profile open and rounded at the bottom in a circular shape for receiving the hook on the next roller shutter rod, the substantially parallel side walls of the Chamber are formed by sharp edged back bending of the main profile sections and the back bending on the one main section at the end bent into the chamber of a double-walled counter hook for the hook of the next roller shutter tabes is located.

Bei Rolläden, die aus solchen Rolladenstäben zusammengesetzt sind, ergibt sich unter anderem das Problem, daß die Deckbreite groß sein soll, was aber bekanntennaßen den Nachteil mit sich bringt, daß der Durchmesser des aufgewickelten Rolladenpanzers relativ groß ist.In the case of roller shutters which are composed of such roller shutter slats, there arises, among other things, the problem that the covering width should be large, but which, as is known, has the disadvantage that the diameter of the wound roller shutter curtain is relatively large.

Mit dieser Frage beschäftigt sich unter anderem die Druckschrift EP 0 167 137 B1, die sich allerdings ausschließlich mit der Entwicklung eines sogenannten Mini-Profils beschäftigt, d.h. einem Hohlkammerprofil das ca. 31 bis 33 mm Deckbreite hat. Dieses Profil ist nur begrenzt einsetzbar, so für kleinere Fenster-Öffnungen oder andere Öffnungen an Gebäuden.This question is dealt with, inter alia, in the publication EP 0 167 137 B1, which, however, deals exclusively with the development of a so-called mini profile, i.e. a hollow chamber profile that has a cover width of approx. 31 to 33 mm. This profile can only be used to a limited extent, for smaller window openings or other openings on buildings.

Der Erfindung liegt die Aufgabe zugrunde, einen Rolladenstab der eingangs näher bezeichneten Art zu schaffen, der bei großer Deckbreite gewährleistet, daß trotzdem der aufgewickelte Rolladenpanzer einen verhältnismäßig kleinen Durchmesser aufweist.The invention has for its object to provide a roller shutter rod of the type specified in the introduction, which ensures with a large covering width that the wound roller shutter armor still has a relatively small diameter.

Diese Aufgabe wird dadurch gelöst, daß die folgenden Profilabmessungen unter Einbeziehung der angegebenen Toleranzen vorgesehen sind:

  • die Wandstärke des Hohlkammerprofils beträgt ca. 0,3 mm;
  • die Deckbreite beträgt 45,5 mm;
  • der Krümmungsradius des außenseitigen Hauptabschnittes beträgt 78 mm;
  • der Krümmungsradius des innenliegenden Hauptabschnittes beträgt 41 mm;
  • der Abstand zwischen den Hauptabschnitten beträgt an der engsten Stelle 3,1 mm;
  • der Haken hat eine Länge von 6,5 mm und eine äußere Breite am Hakenkopf von 3,2 mm und ist mit seinem geraden Schaft gegenüber der Längserstreckung um 3 ° in Richtung innenliegender Hauptabschnitt geneigt;
  • die Kammer hat zwischen den Seitenwänden eine Weite von 3,5 mm und eine Länge, gemessen von der Rückbiegung des außenliegenden Hauptabschnittes bis zum Kammerboden, von 7,05 mm und der Gegenhaken ist gegenüber der Längserstreckung um 3 ° in Richtung des außenliegenden Hauptabschnittes geneigt;
  • die Profilhöhe beträgt 8,9 mm.
This object is achieved in that the following profile dimensions are provided taking into account the specified tolerances:
  • the wall thickness of the hollow chamber profile is approx. 0.3 mm;
  • the deck width is 45.5 mm;
  • the radius of curvature of the outer main section is 78 mm;
  • the radius of curvature of the inner main section is 41 mm;
  • the distance between the main sections is 3.1 mm at the narrowest point;
  • the hook has a length of 6.5 mm and an outer width at the hook head of 3.2 mm and, with its straight shaft, is inclined by 3 ° in relation to the longitudinal extension in the direction of the inner main section;
  • the chamber has a width of 3.5 mm between the side walls and a length, measured from the back bend of the outer main section to the chamber floor, of 7.05 mm and the counter hook is inclined by 3 ° in the direction of the outer main section with respect to the longitudinal extent;
  • the profile height is 8.9 mm.

Gemäß einer Weiterbildung der Erfindung ist vorgesehen, daß das Hohlkammerprofil aus Metall besteht.According to a development of the invention, it is provided that the hollow chamber profile consists of metal.

Erfindungsgemäß ist es, daß das Hohlkammerprofil aus Aluminium, Stahl oder Kunststoff bestehen kann.It is according to the invention that the hollow chamber profile can consist of aluminum, steel or plastic.

Gemäß der Erfindung kann auch vorgesehen sein, daß die aus Metall bestehenden Hohlkammerprofile mit Kunststoff ausgeschäumt sind.According to the invention it can also be provided that the hollow chamber profiles made of metal are foamed with plastic.

Im Rahmen der Erfindung liegt es auch, daß der Gegenhaken um 15 ° zur Vertikalen in Richtung der Kammer angeordnet ist.It is also within the scope of the invention that the counter hook is arranged at 15 ° to the vertical in the direction of the chamber.

Die mit der Erfindung erzielten Vorteile bestehen im wesentlichen darin, daß bei großer Deckbreite ein relativ kleiner Wickeldurchmesser des Rolladenpanzers gegeben ist. Durch die erfindungsgemäße Formgebung eines Rolladenstabs ist weniger Materialaufwand erforderlich (geringere Blechbreite), was insbesondere dann zu Buche schlägt, wenn der Rolladenstab aus Aluminiumband gerollformt ist. Auch kann durch die neue Form des Rolladenstabs die Wandung des Hohlkammerprofils (aus Aluminium) dünner gewählt werden bei gleicher Steifigkeit wie früher. Auch wurde bei dem neuen Profil die Schulterschräge (Innenseite des Profils) stark vergrößert, was beim Aufwickeln ein Einklemmen des Nachbarprofils verhindert. Diesem Ziel dient auch die Abstimmung der Deckbreite und des Krümmungsradius des außenliegenden Hauptabschnitts. Durch eine abgestimmte Hakenstielneigung gegenüber der Kammerneigung ergibt sich beim Zusammenschieben des Rolladenpanzers eine absolute Lichtundurchlässigkeit; die obere Hakenschulter wird hierbei gegen die Tropfnase des Nachbarprofils gezogen, die untere Hakenschulter gegen die geneigte Außenwand der Kammer.The advantages achieved with the invention consist essentially in the fact that a relatively small winding diameter of the roller shutter curtain is given with a large covering width. The inventive design of a roller shutter rod means that less material is required (smaller sheet width), which is particularly noticeable when the roller shutter rod is rolled from aluminum strip. Thanks to the new shape of the roller shutter slat, the wall of the hollow chamber profile (made of aluminum) can be made thinner with the same stiffness as before. The shoulder slope (inside of the profile) of the new profile has also been greatly enlarged, which prevents the neighboring profile from being caught when it is rolled up. The purpose of this is also to coordinate the covering width and the radius of curvature of the outer main section. A coordinated inclination of the hook handle relative to the inclination of the chamber results in an absolute opacity when the roller shutter curtain is pushed together; the upper hook shoulder is pulled against the drip nose of the neighboring profile, the lower hook shoulder against the inclined outer wall of the chamber.

Die Erfindung wird anhand der Zeichnung näher beschrieben.The invention is described in more detail with reference to the drawing.

- Rolladenstäbe dieser Art und aus solchen Rolladenstäben hergestellte Rolladenpanzer sind an sich bekannt, weshalb hier auf die Darstellung weiterer Details verzichtet wurde. Insofern wird ausdrücklich Bezug genommen auf die einleitend genannte Druckschrift.- Roller shutter slats of this type and roller shutter armor made from such roller shutter slats are known per se, which is why no further details are shown here. In this respect, reference is expressly made to the publication mentioned in the introduction.

In der Zeichnung ist das erfindungsgemäße Hohlkammerprofil 2 in Stirnansicht dargestellt unter Angabe der für die Erfindung charakteristischen Profilabmessungen und deren zulässigen Toleranzen.In the drawing, the hollow chamber profile 2 according to the invention is shown in front view, indicating the profile dimensions characteristic of the invention and their permissible tolerances.

Durch die Optimierung der Abmessungen des Hohlkammerprofils 2 gemäß dem Patentanspruch kann die Wandstärke 1 des Hohlkammerprofils 2 geringer als bei bisher bekannten Profilen gewählt werden: während bei der Erfindung die Wandstärke 1 ca. 0,3 mm beträgt, ist die Wandstärke bei einem vergleichbaren bekannten Profil 0,45 mm. Das ist insbesondere dann von Bedeutung, wenn, wie heute in großem Umfang praktiziert, das Hohlkammerprofil aus gerollformtem Aluminiumband besteht.By optimizing the dimensions of the hollow chamber profile 2 according to the claim, the wall thickness 1 of the hollow chamber profile 2 can be chosen to be smaller than in previously known profiles: while in the invention the wall thickness 1 is approximately 0.3 mm, the wall thickness is in a comparable known profile 0.45 mm. This is particularly important when, as is practiced on a large scale today, the hollow chamber profile consists of rolled aluminum strip.

Die erfindungsgemäße Optimierung der Abmessungen des Hohlkammerprofils hat auch zur Folge, daß bei Aluminium in Bandform zum Rollformen des Hohlkammerprofils 2 eine geringere Blechbreite als bisher gewählt werden kann, was neben der geringeren Materialstärke (Wandstärke 1) einer zusätzlichen Materialersparnis gleichkommt.The optimization of the dimensions of the hollow chamber profile according to the invention also has the consequence that in the case of aluminum in strip form for roll forming the hollow chamber profile 2, a smaller sheet width can be chosen than before, which in addition to the lower material thickness (wall thickness 1) equates to an additional material saving.

Das Hohlkammerprofil 2 hat einen zentralen Hohlraum 12, an dessen einem Ende der Haken 7 und an dessen anderem Ende eine nach außen offene Kammer 9 mit einem Gegenhaken 10 angeordnet ist. Der zentrale Hohlraum 12 befindet sich zwischen einem außenseitigen Hauptabschnitt 4, dessen Krümmungsradius 78 mm beträgt und einem innenliegenden Hauptabschnitt 5, dessen Krümmungsradius 41 mm beträgt.The hollow chamber profile 2 has a central cavity 12, at one end of which the hook 7 and at the other end an outwardly open chamber 9 with a counter hook 10 is arranged. The central cavity 12 is located between an outer main section 4, the radius of curvature of which is 78 mm, and an inner main section 5, whose radius of curvature is 41 mm.

Die Deckbreite 3 beträgt 45,5 mm, was eine deutliche Verbesserung gegenüber einem herkömmlichen Profil bedeutet, wo die Deckbreite 42 mm beträgt.The deck width 3 is 45.5 mm, which is a significant improvement over a conventional profile, where the deck width is 42 mm.

Und trotz dieser großen Deckbreite 3 ergibt sich ein relativ kleiner Wickeldurchmesser eines Rolladenpanzers, der aus erfindungsgemäßen Profilen zusammengesetzt ist: gegenüber einem Rolladenpanzer aus einem vergleichbaren bekannten Profil mit vorgegebener Höhe des Panzers (2500 mm) ergibt sich bei Verwendung des erfindungsgemäßen Hohlkammerprofils 2 ein Minus von ca. 20 mm des aufgewickelten Rolladenpanzers, was eine erhebliche Verringerung in der Praxis bedeutet.And despite this large covering width 3, there is a relatively small winding diameter of a roller shutter armor, which is composed of profiles according to the invention: compared to a roller shutter armor made of a comparable known profile with a predetermined height of the armor (2500 mm), using the hollow chamber profile 2 according to the invention results in a minus of approx. 20 mm of the rolled-up roller shutter armor, which means a considerable reduction in practice.

Der Abstand zwischen den Hauptabschnitten 4 und 5 beträgt an der engsten Stelle 3,1 mm.The distance between the main sections 4 and 5 is 3.1 mm at the narrowest point.

Der Haken 7 hat eine Länge von 6,5 mm und eine äußere Breite am Hakenkopf von 3,2 mm und ist mit seinem geraden Schaft gegenüber der Längserstreckung 8 um 3 ° in Richtung innenliegender Hauptabschnitt 5 geneigt.The hook 7 has a length of 6.5 mm and an outer width at the hook head of 3.2 mm and its straight shaft is inclined by 3 ° in relation to the longitudinal extension 8 in the direction of the inner main section 5.

Die Kammer 9 hat zwischen den Seitenwänden eine Weite von 3,5 mm und eine Länge, gemessen von der Rückbiegung des außenliegenden Hauptabschnittes 4 bis zum Kammerboden, von 7,05 mm und der Gegenhaken 10 ist gegenüber der Längserstreckung 8 um 3 ° in Richtung des außenliegenden Hauptabschnittes 4 geneigt. Erfindungsgemäß kann der Gegenhaken 10 um 15 ° zur Vertikalen in Richtung der Kammer 9 angeordnet sein.The chamber 9 has between the side walls a width of 3.5 mm and a length, measured from the back bend of the outer main section 4 to the chamber bottom, of 7.05 mm and the counter hook 10 is 3 ° in the direction of the longitudinal extension 8 outer main section 4 inclined. According to the invention, the counter hook 10 can be arranged at 15 ° to the vertical in the direction of the chamber 9.

Die Profilhöhe 11 des Hohlkammerprofils 2 beträgt 8,9 mm.The profile height 11 of the hollow chamber profile 2 is 8.9 mm.

Bemerkenswert ist die erfindungsgemäße Abstimmung der Deckbreite 3 und des Krümmungsradius des außenliegenden Hauptabschnittes 4, wodurch beim Aufwickeln ein Einklemmen der aufeinanderliegenden Profile ausgeschlossen ist. Die beschriebene Neigung des Hakens 7 im Verhältnis zur Neigung des Gegenhakens 10 führt bei zusammengeschobenem Rolladen zur Lichtundurchlässigkeit.It is noteworthy that the covering width 3 and the radius of curvature of the outer main section 4 are coordinated according to the invention, as a result of which jamming of the profiles lying on one another during the winding is excluded. The described inclination of the hook 7 in relation to the inclination of the counter-hook 10 leads to opacity when the roller shutters are pushed together.

Das Optimieren der Abmessungen eines Hohlkammerprofils 2 gemäß der Erfindung führt zu den angegebenen Vorteilen, wozu auch noch gehört, daß das übliche Knacken beim Aufwikkeln des Rolladenpanzers, das durch Einsetzen der Tropfnase in den Zwischenraum zweier benachbarter Profile entsteht, bei Verwendung des erfindungsgemäßen Profils entfällt.The optimization of the dimensions of a hollow chamber profile 2 according to the invention leads to the stated advantages, which also includes the fact that the usual cracking when winding up the roller shutter curtain, which is caused by inserting the drip nose into the space between two adjacent profiles, is eliminated when using the profile according to the invention.
