Definitions
- the invention relates to a roller shutter according to the preamble of claim 1. More particularly, the invention relates to a roller shutter with profile rods at least partially made of a bamboo composite material. The invention also relates to a folding shutter made of the same material and the use of such a material for a roller shutter or folding shutter.
- roller blinds The origins of the roller shutter are rooted in simple wooden folding shutters. Such shutters were already used in Roman times and served as privacy screens. In the 18th century, the French developed blinds that were initially rigid and later pulled together by means of tapes (pull-type blinds). In a further step, blinds were developed that could be rolled up by means of a shaft (roller blinds). This is how today's roller shutter emerged.
- Wooden shutters must be protected against the weather. To do this, glazes and varnishes are used. They can be used up to a large width and offer good burglar resistance, but are also very expensive, heavy, require a lot of maintenance and are susceptible to weathering. They do not have any light slots, but can be made with an extendable chain. Since wooden shutters are made from renewable raw materials, they are highly recommended from an ecological point of view. Today they are only produced by a few manufacturers (quotations from WIKIPEDIA).
- the materials used should remain similar to the known wood materials. You should be able to work like this, i.e. be able to work with woodworking tools and machines. In particular, they should be able to be sawed, milled and drilled like known wood materials.
- roller shutters made from these materials should not have to differ significantly from known wooden roller shutters.
- the roller shutter therefore comprises profile rods consisting at least partially of a bamboo composite material.
- composite materials are known, but have so far mainly been used for structural tasks in buildings, in particular as (exterior) wall cladding and as a component of building floors, for example as a floor covering layer.
- the roller shutter comprises a plurality of profile rods arranged essentially parallel to one another and connecting elements connecting adjacent profile rods which allow a relative movement of the profile rods in which the distance between the adjacent profile rods changes.
- the roller shutter can be a folding roller shutter or a wound roller shutter.
- roller shutter is preferably generally the structure disclosed in our simultaneously filed European patent application entitled "Roller shutter”.
- the profile bars consist of a solid material that is brought into the desired shape by mechanical processing (sawing, milling, drilling, etc.).
- the material of the profile bars is a fully recyclable bamboo material that is compressed under high pressure. It comprises strips of natural Moso bamboo ( Phyllostachys edulis ) that are formed into sheets after compaction and heat treatment.
- the material is e.g. B. commercially available under the name "MOSO bamboo X-treme" from Moso Italia Srl.
- this material according to the invention makes it possible to produce roller shutters based on bamboo, which is practically impossible with naturally occurring bamboo sections.
- the material is extremely strong and is therefore not only suitable for roller shutters, but also for the above-mentioned folding shutters.
- the production of such folding shutters is conventional, only the bamboo composite material already defined above is used instead of natural wood according to the invention.

Abstract
Rollladen mit mehreren miteinander begrenzt beweglich verbundenen Profilstäben, dadurch gekennzeichnet, dass die Profilstäbe wenigstens zum Teil und vorzugsweise aus einem Bambus-Verbundmaterial bestehenRoller shutter with several profile rods connected to one another in limited mobility, characterized in that the profile rods consist at least in part and preferably of a bamboo composite material
Description
Die Erfindung betrifft einen Rollladen gemäß der Präambel von Anspruch 1. Spezieller betrifft die Erfindung einen Rollladen mit wenigstens teilweise aus einem Bambus-Verbundmaterial bestehenden Profilstäben. Weiterhin betrifft die Erfindung einen Klappladen aus dem gleichen Material und die Verwendung eines solchen Materials für einen Rollladen oder Klappladen.The invention relates to a roller shutter according to the preamble of claim 1. More particularly, the invention relates to a roller shutter with profile rods at least partially made of a bamboo composite material. The invention also relates to a folding shutter made of the same material and the use of such a material for a roller shutter or folding shutter.
Die Ursprünge des Rollladens wurzeln in einfachen Klappläden aus Holz. Solche Klappläden wurden schon in der Römerzeit verwendet und dienten als Sichtschutz. Im 18. Jahrhundert entwickelten die Franzosen Jalousien, die zuerst starr, später mittels Bändern zusammenziehbar waren (Zugjalousien). In einem weiteren Schritt wurden Jalousien entwickelt, die mittels einer Welle aufrollbar waren (Rolljalousien). Daraus entstand der heutige Rollladen.The origins of the roller shutter are rooted in simple wooden folding shutters. Such shutters were already used in Roman times and served as privacy screens. In the 18th century, the French developed blinds that were initially rigid and later pulled together by means of tapes (pull-type blinds). In a further step, blinds were developed that could be rolled up by means of a shaft (roller blinds). This is how today's roller shutter emerged.
Der Rollpanzer oder Rollladenbehang eines Rollladens besteht aus gelenkig miteinander verbundenen Rollladenstäben (auch Rollladenprofile genannt). Er ist das schützende Teil des Rollabschlusses, das die Öffnung schließt. Je nach Anforderungen kann er verschieden beschaffen sein. Die am häufigsten verwendeten Materialien sind:
- Kunststoff, vorwiegend Hart-PVC,
- Aluminium, oft mit Polyurethan ausgeschäumt,
- Holz, in der Regel Kiefernholz,
- Stahl oder rostfreier Stahl
- Plastic, mainly hard PVC,
- Aluminum, often foamed with polyurethane,
- Wood, usually pine,
- Steel or stainless steel
Holzrollläden müssen gegen Witterungseinflüsse geschützt werden. Dazu benutzt man Lasuren und Lacke. Sie können bis zu einer großen Breite verwendet werden und bieten eine gute Einbruchhemmung, sind aber auch sehr teuer, schwer, pflegeintensiv und witterungsanfällig. Sie besitzen zwar keine Lichtschlitze, können aber mit einer ausziehbaren Kettung hergestellt werden. Da Holzrollläden aus nachwachsendem Rohstoff gefertigt werden, sind sie unter ökologischen Gesichtspunkten sehr empfehlenswert. Sie werden heute nur noch von wenigen Herstellern gefertigt (Zitate aus WIKIPEDIA). Wooden shutters must be protected against the weather. To do this, glazes and varnishes are used. They can be used up to a large width and offer good burglar resistance, but are also very expensive, heavy, require a lot of maintenance and are susceptible to weathering. They do not have any light slots, but can be made with an extendable chain. Since wooden shutters are made from renewable raw materials, they are highly recommended from an ecological point of view. Today they are only produced by a few manufacturers (quotations from WIKIPEDIA).
Es wäre angesichts dieser und anderer Vorteile von Holzrollläden wünschenswert, eine kostengünstige, weniger pflegeintensive und weniger witterungsanfällige Alternative zu den bekannten Holzmaterialien aufzuzeigen, die die genannten Vorteile bekannter Holzrollläden dennoch aufweist.In view of these and other advantages of wooden shutters, it would be desirable to show an inexpensive, less maintenance-intensive and less weather-prone alternative to the known wooden materials, which nevertheless has the mentioned advantages of known wooden shutters.
Hierin liegt eine wichtige Aufgabe der Erfindung.This is an important object of the invention.
Dabei sollen die verwendeten Materialien den bekannten Holzmaterialien ähnlich bleiben. Sie sollen sich wie diese bearbeiten lassen, also mit Holzbearbeitungswerkzeugen und -maschinen bearbeitet werden können. Insbesondere sollen sie wie bekannte Holzmaterialien gesägt, gefräst und gebohrt werden können.The materials used should remain similar to the known wood materials. You should be able to work like this, i.e. be able to work with woodworking tools and machines. In particular, they should be able to be sawed, milled and drilled like known wood materials.
Der aus diesen Materialien gefertigte Rollladen soll sich im Übrigen von bekannten HolzRollläden nicht wesentlich unterscheiden müssen.Incidentally, the roller shutters made from these materials should not have to differ significantly from known wooden roller shutters.
Zur Lösung dieser Aufgabe dient die im Patentanspruch 1 definierte Merkmalskombination. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Patentansprüchen definiert.The combination of features defined in claim 1 is used to solve this problem. Advantageous further developments of the invention are defined in the dependent claims.
Erfindungsgemäß umfasst der Rollladen daher wenigstens teilweise aus einem Bambus-Verbundmaterial bestehende Profilstäbe. Solche Verbundmaterialien sind bekannt, werden aber bisher hauptsächlich für strukturelle Aufgaben in Gebäuden eingesetzt, insbesondere als (Außen-) Wandverkleidung und als Bestandteil von Gebäudeböden, etwa als Fußboden-Deckschicht.According to the invention, the roller shutter therefore comprises profile rods consisting at least partially of a bamboo composite material. Such composite materials are known, but have so far mainly been used for structural tasks in buildings, in particular as (exterior) wall cladding and as a component of building floors, for example as a floor covering layer.
Weitere Aufgaben und Vorteile der Erfindung ergeben sich aus der folgenden Beschreibung, die bevorzugte Ausführungsformen der Erfindung offenbart.Further objects and advantages of the invention will become apparent from the following description which discloses preferred embodiments of the invention.
Bei der gegenwärtig meist bevorzugten Ausführungsform der Erfindung umfasst der Rollladen mehrere im Wesentlichen parallel zueinander angeordnete Profilstäben und benachbarte Profilstäbe miteinander verbindende Verbindungselementen, welche eine Relativbewegung der Profilstäbe gestatten, bei welcher sich der Abstand der benachbarten Profilstäbe voneinander verändert.In the currently most preferred embodiment of the invention, the roller shutter comprises a plurality of profile rods arranged essentially parallel to one another and connecting elements connecting adjacent profile rods which allow a relative movement of the profile rods in which the distance between the adjacent profile rods changes.
Der Rollladen kann ein Faltrollladen oder ein gewickelter Rollladen sein.The roller shutter can be a folding roller shutter or a wound roller shutter.
Die Struktur des Rollladens ist vorzugsweise generell die in unserer zeitgleich eingereichten europäischen Patentanmeldung mit dem Titel "Rollladen" offenbarte Struktur.The structure of the roller shutter is preferably generally the structure disclosed in our simultaneously filed European patent application entitled "Roller shutter".
Bei dieser Ausführungsform bestehen die Profilstäbe aus einem Vollmaterial, das durch mechanische Bearbeitung (Sägen, Fräsen, Bohren etc.) in die gewünschte Form gebracht wird.
Das Material der Profilstäbe ist ein unter Hochdruck verdichtetes, vollständig recyclebares Bambusmaterial. Es umfasst Streifen von natürlichem Moso-Bambus (Phyllostachys edulis), die nach Verdichtung und Wärmebehandlung zu Platten geformt werden. Das Material ist z. B. unter der Bezeichnung "MOSO Bamboo X-treme" von Moso Italia Srl kommerziell erhältlich.In this embodiment, the profile bars consist of a solid material that is brought into the desired shape by mechanical processing (sawing, milling, drilling, etc.).
The material of the profile bars is a fully recyclable bamboo material that is compressed under high pressure. It comprises strips of natural Moso bamboo ( Phyllostachys edulis ) that are formed into sheets after compaction and heat treatment. The material is e.g. B. commercially available under the name "MOSO Bamboo X-treme" from Moso Italia Srl.

- e) dimensional stability (length + 0.1%; width + 0.9%);
- f) Fire resistance: class Bfl-s1 (EN 13501-1);
- g) Efficiency against Blue Stain Fungus: Class 0 (EN152);
- h) CO2 neutral (ISO 14040/44).
Die erfindungsgemässe Verwendung dieses Materials macht es möglich, Rollläden auf Bambus-Basis herzustellen, was mit natürlich vorkommenden Bambus-Abschnitten praktisch nicht möglich ist.The use of this material according to the invention makes it possible to produce roller shutters based on bamboo, which is practically impossible with naturally occurring bamboo sections.
Das Material ist von enormer Festigkeit und eignet sich daher nicht nur für Rollläden, sondern auch für die schon erwähnten Klappläden. Die Fertigung solcher Klappläden ist herkömmlich, nur wird erfindungsgemäß das oben schon definierte Bambus-Verbundmaterial statt natürlichem Holz verwendet.The material is extremely strong and is therefore not only suitable for roller shutters, but also for the above-mentioned folding shutters. The production of such folding shutters is conventional, only the bamboo composite material already defined above is used instead of natural wood according to the invention.
