Description

Die Erfindung betrifft ein Rollladenprofil mit einem längs einer seiner Schmalseiten verlaufenden, eine Vielzahl von Öffnungen aufweisenden Steg, der mit einer Querleiste versehen ist und mit einem Schlitz längs der dem Steg gegenüberliegenden anderen Schmalseite, der mit dem Steg und der Querleiste eines benachbarten Rollladenprofils in Eingriff bringbar ist.The invention relates to a roller shutter profile with a along one of its narrow sides extending, having a plurality of openings web, which is provided with a transverse bar and with a slot along the opposite side of the web other narrow side which engages with the web and the cross bar of an adjacent roller shutter profile can be brought.

Ein gattungsgemäßer Rollladen ist aus der DE 40 20 377 bekannt.
Bei dem bekannten Rollladenstab, der mit einem längs einer seiner Schmalseite verlaufenden, eine Vielzahl von kreisförmigen Öffnungen versehenen Steg, der mit einer Querleiste versehen ist und mit einem Schlitz längs der dem Steg gegenüberliegenden anderen Schmalseite, der mit dem Steg und der Querleiste des benachbarten Profilkörpers in Eingriff bringbar ist, soll einen ausreichenden Insektenschutz mit guten Lüftungs- und Lichtdurchtrittseigenschafen verbinden.
Dies soll dadurch gelöst werden, dass die Achse der Öffnungen zur Senkrechten auf die Ebene, welche durch den Steg gebildet ist, einen Winkel von 10° bis 20° einschließt und dass die Öffnungen an ihrer engsten Durchtrittsstelle einen Durchmesser von zwischen 1,0 und 2,0 mm aufweisen.
Weiterhin sollen die Öffnungen konisch ausgebildet sein. In weiteren Ausführungen sind die Öffnungen in übereinander liegenden Reihen bzw. zueinander versetzt angeordnet.A generic shutter is from the DE 40 20 377 known.
In the known roller shutter bar, which is provided with a along one of its narrow side extending, a plurality of circular openings provided web, which is provided with a transverse bar and with a slot along the other narrow side opposite the web, with the web and the cross bar of the adjacent profile body is engageable, should connect a sufficient insect protection with good ventilation and Lichtdurchtrittseigenschafen.
This is to be achieved in that the axis of the openings to the vertical to the plane which is formed by the web, an angle of 10 ° to 20 ° includes and that the openings at their narrowest passage point has a diameter of between 1.0 and 2 , 0 mm.
Furthermore, the openings should be conical. In other embodiments, the openings are arranged in rows one above the other or offset from each other.

Nachteilig bei einem derartigen Rollladenprofil hat sich jedoch herausgestellt, dass durch die Vielzahl der unmittelbar nebeneinander angeordneten kreisrunden Öffnungen die mechanischen Eigenschaften dieses Rollladenprofils, insbesondere die Festigkeitswerte, sehr negativ beeinflusst werden. Durch die Vielzahl der Öffnungen wird der Steg stark geschwächt, so dass es beispielsweise bei sehr breiten und langen Rollladen zu erhöhten Belastungen kommt.
Ein weiterer Nachteil wird darin gesehen, das die Öffnungen bei dem bekannten Rollladen durch Luftbelastungen wie Staub, insbesondere Blütenstaub zugesetzt werden und somit verschlossen sind.A disadvantage of such a roller shutter profile has been found, however, that the mechanical properties of this roller shutter profile, in particular the strength values, are very negatively influenced by the large number of circular openings arranged directly next to each other. Due to the large number of openings of the web is greatly weakened, so that it comes, for example, in very wide and long blinds to increased loads.
Another disadvantage is seen in the fact that the openings are added in the known roller shutter by air pollution such as dust, especially pollen and thus closed.

Weiterhin nachteilig wird gesehen, dass durch die kleinen Öffnungen von ca. 1 mm Durchmesser die gewünschten Lüftungs- und Lichtdurchtrittseigenschaften in der Praxis nicht realisierbar sind.
Auch die bei diesem Rollladen beschriebenen Geometrien und Positionen der kreisrunden Öffnungen erweisen sich als nachteilig, da das Einbringen von konisch ausgebildeten kreisrunden Öffnungen den Herstellungsaufwand eines derartigen Rollladenprofils unnötig erhöht und damit den Roll-Laden verteuert.
Das Einbringen von kreisförmigen Öffnungen, bei denen sich der Konus gegen die äußere Breitseite des Rollladenstabes verjüngt, ist in einer derartigen Ausführung nicht fertigbar. Das Einbringen von kreisförmigen Öffnungen, deren Achsen in einem bestimmten Winkel zum Steg ausgebildet sind, führt zu erheblichen fertigungstechnischen Problemen, da insbesondere im Bereich der unteren Reihe der kreisförmigen Öffnungen die Schmalseite des Rollladenprofils durch das Gegenlager stark beansprucht wird und es hier zu einer Vorschädigung besagter Schmalseite sowie des Steges führt. Durch die schräg eingebrachten Öffnungen im Steg werden die Lüftungs- und Lichtdurchtrittseigenschaften noch einmal erheblich verschlechtert, da die Schrägen der kreisförmigen Öffnungen parallel zueinander ausgebildet für den Betrachter und Nutzer derartiger Rollladenprofile den Querschnitt an sich reduzieren.Another disadvantage is seen that the desired ventilation and light transmission properties are not feasible in practice by the small openings of about 1 mm diameter.
The geometries and positions of the circular openings described in this roller shutter prove to be disadvantageous, since the introduction of conical circular openings unnecessarily increases the production cost of such a roller shutter profile and thus makes the roller shutter more expensive.
The introduction of circular openings, in which the cone tapers against the outer broad side of the roller shutter bar, is not manufacturable in such an embodiment. The introduction of circular openings whose axes are formed at a certain angle to the web, leading to considerable manufacturing problems, since in particular in the region of the lower row of circular openings, the narrow side of the roller shutter profile is heavily stressed by the anvil and said it to a previous damage Narrow side and the bridge leads. Due to the obliquely introduced openings in the web, the ventilation and light transmission properties are once again significantly worsened, since the slopes of the circular openings parallel to each other for the viewer and users of such roller shutter profiles reduce the cross section in itself.

Hier setzt die Erfindung ein, die es sich zur Aufgabe gestellt hat, die Nachteile des bekannten Standes der Technik zu überwinden und ein Rollladenprofil aufzuzeigen, welches bei besseren mechanischen Eigenschaften einen steuerbaren Lüftungs- und Lichtdurchgang realisiert und welches wirtschaftlich und preisgünstig herstellbar ist.This is where the invention, which has set itself the task of overcoming the disadvantages of the known prior art and to show a roller shutter profile, which realizes a controllable ventilation and light passage with better mechanical properties and which is economical and inexpensive to produce.

Die Aufgabe der Erfindung wird durch die kennzeichnenden Merkmale des Anspruches 1 in Verbindung mit den Merkmalen des Oberbegriffes gelöst.
In den Unteransprüchen werden bevorzugte Ausführungsformen beschrieben.The object of the invention is achieved by the characterizing features of claim 1 in conjunction with the features of the preamble.
In the dependent claims preferred embodiments are described.

Bei dem erfindungsgemäßen Rollladenprofil sind die Öffnungen als danglöcher ausgebildet und weisen orthogonal zur Querleiste des Rollladenprofils eine größere Abmessung auf als parallel zur Querleiste, wobei der Abstand der Öffnungen im Steg etwa ihrer Breite entspricht. Die Achsen der Öffnungen des erfindungsgemäßen Rollladenprofils sind orthogonal zum Steg angeordnet, wobei ihr Abstand in etwa der doppelten Wandstärke des Steges entspricht.In the roller shutter profile according to the invention, the openings are formed as danglöcher and have orthogonal to the transverse strip of the roller shutter profile a larger dimension than parallel to the transverse strip, wherein the distance of the openings in the web corresponds approximately to its width. The axes of the openings of the roller shutter profile according to the invention are arranged orthogonal to the web, wherein their distance corresponds approximately to twice the wall thickness of the web.

  • Fig. 1 - Perspective partial view of the roller shutter profile according to the invention
  • Fig. 2 - Sectional view of inventive roller shutter profiles

In Fig. 1 wird in perspektivischer Teilansicht das Rollladenprofil 1 dargestellt, welches an seiner Schmalseite 6 einen Steg 2 mit einer Querleiste 3 aufweist. Das Rollladenprofil 1 besteht im Wesentlichen aus verschieden dimensionierten Hohlkammern 11, 12, 13,14 und 16, wobei an der der Schmalseite 6 gegenüberliegenden Schmalseite 7 eine weitere Hohlkammer 15 angeordnet ist, in die der Schlitz 5 eingebracht ist. In den Steg 2 des Rollladenprofils 1 sind die Öffnungen 4 eingebracht, welche als Langlöcher ausgebildet und in regelmäßigen Abständen zueinander angeordnet sind.
Durch die Öffnungen 4 des erfindungsgemäßen Rolladenprofils1 ist nicht nur ein steuerbarer, sondern auch ein höherer Lüftungs- und Lichtdurchtritt in die entsprechenden Räume möglich. Damit wird ein positiver Einfluss auf das Wohlbefinden der in den Räumen wohnenden Menschen, als auch auf das Wachstum und den Schutz von an den Gebäudeöffnungen positionierten Zimmerpflanzen erreicht.
Das erfindungsgemäße Rollladenprofil 1 kann sowohl aus einem polymeren als auch aus einem metallischen Werkstoff hergestellt werden.In Fig. 1 is shown in perspective partial view of the roller shutter profile 1, which has on its narrow side 6 a web 2 with a transverse bar 3. The roller shutter profile 1 consists essentially of different sized hollow chambers 11, 12, 13,14 and 16, wherein on the narrow side 6 opposite narrow side 7, a further hollow chamber 15 is arranged, in which the slot 5 is introduced. In the web 2 of the roller shutter profile 1, the openings 4 are introduced, which are formed as elongated holes and arranged at regular intervals from each other.
Through the openings 4 of the invention Rolladenprofils1 not only a controllable, but also a higher ventilation and light passage into the corresponding rooms is possible. This will have a positive effect on the well-being of people living in the rooms, as well as on the growth and protection of indoor plants positioned at the building openings.
The roller shutter profile 1 according to the invention can be produced both from a polymeric material and from a metallic material.

In Fig. 2 ist eine Schnittdarstellung durch das erfindungsgemäße Rollladenprofil 1 sowie ein benachbart angeordnetes Rollladenprofil 10 dargestellt. An der Schmalseite 6 des Rollladenprofils 1 ist der Steg 2 angeformt, in den die Öffnung 4 eingebracht ist. Die Achsen 41, 42 der Öffnung 4 sind orthogonal zum Steg 2 angeordnet, wobei ihr Abstand zueinander etwa der doppelten Wandstärke des Steges 2 entspricht. Der Steg 2 ist mit einer Querleiste 3 verbunden, und über den an der Schmalseite 7 des Rollladenprofils 10 befindlichen Schlitz 5 in der Hohlkammer 15 des Rollladenprofils 10 eingebracht. In diesem Ausführungsbeispiel sind die Öffnungen 4 so angeordnet, dass die Achse 42 der Öffnung 4 in etwa mit der Unterkante der Schmalseite 7 des Rollladenprofils 10 übereinstimmt, so dass ein optimaler Lüftungs- und Lichtdurchtritt beim erfindungsgemäßen Rollladenprofils 1 gewährleistet ist.In Fig. 2 is a sectional view through the roller shutter profile 1 according to the invention and an adjacently arranged roller shutter profile 10 is shown. On the narrow side 6 of the roller shutter profile 1, the web 2 is formed, in which the opening 4 is introduced. The axes 41, 42 of the opening 4 are arranged orthogonal to the web 2, wherein their distance from one another corresponds approximately to twice the wall thickness of the web 2. The web 2 is connected to a transverse bar 3, and introduced via the located on the narrow side 7 of the roller shutter profile 10 slot 5 in the hollow chamber 15 of the roller shutter profile 10. In this embodiment, the openings 4 are arranged so that the axis 42 of the opening 4 approximately coincides with the lower edge of the narrow side 7 of the roller shutter profile 10, so that an optimal ventilation and light passage is ensured in the roller shutter profiles 1 according to the invention.

Ein weiterer Vorteil des erfindungsgemäßen Rollladenprofils 1 wird darin gesehen, dass die Öffnungen 4 orthogonal zur Querleiste 3 des Rollladenprofils 1 eine größere Abmessung aufweisen als parallel zur Querleiste 3. Somit ist in der Nutzung eines Rollladens, bestehend aus den erfindungsgemäßen Rollladenprofilen 1, 10 ein steuerbarer Lüftungs- und Lichtdurchtritt erreichbar, da die maximal mögliche Höhe des Steges 3 für den Lüftungs- und Lichtdurchtritt genutzt und durch die verschiedene Positionierung des Rollladenprofils 1 zum Rollladenprofil 10 ein unterschiedlicher Lüftungs- bzw. Lichtdurchtritt erreichbar ist.Another advantage of the roller shutter profile 1 according to the invention is seen in the fact that the openings 4 orthogonal to the cross bar 3 of the roller shutter profile 1 have a larger dimension than parallel to the transverse bar 3. Thus, in the use of a shutter, consisting of the roller shutter profiles 1, 10 according to the invention a controllable Ventilation and light passage can be achieved, since the maximum possible height of the web 3 used for the ventilation and light passage and a different ventilation or light passage can be achieved by the different positioning of the shutter profile 1 to the shutter profile 10.
