Description

Die Erfindung betrifft eine rollbare Schutzfolie aus Kunststoff für Verglasungen, vorzugsweise bestehend aus mehreren Folienschichten.The invention relates to a rollable protective film made of plastic for glazing, preferably consisting of several film layers.

Es ist bekannt, eine derartige rollbare Schutzfolie als Folienrollo zum Schutz gegen Sonne, Wärme, UV-Strahlen sowie als Sichtschutz für Fenster, Schaufenster, Glastrennwände, Glastüren, Wintergartenverglasungen, etc. zu verwenden. Derartige Schutzfolien weisen eine ebene und glatte Oberflächenstruktur auf und können ggf. metallbeschichtet sein. Eine Schutzfolie kann jeweils aus mehreren, unterschiedliche Eigenschaften aufweisenden Schichten bestehen, wodurch der Schutz individuell für den jeweiligen Anwendungsfall abgestimmt werden kann. Derartige Folienrollos können beispielsweise als Tageslichtfilter gegen UV-Strahlen und Blendung eingesetzt werden. Ist kein Schutz mehr notwendig oder erwünscht, kann durch Aufrollen der Folie der ursprüngliche Zustand ohne Sichteinschränkung wieder hergestellt werden. Um die gute Rollbarkeit der Folie zu ermöglichen, ist die Schutzfolie relativ dünn ausgebildet. Dadurch ist allerdings keine ausreichende Verwindungs- und Biegesteifigkeit mehr gegeben und die Folie neigt, insbesondere bei großflächiger Ausbildung, zum sogenannten Schüsseln bzw. Beulen der Oberfläche, wodurch das Erscheinungs- und Reflexionsbild der Schutzfolie nicht mehr gleichmäßig und harmonisch ist. Eine derartige Rollfolie ist in der US 4 202 395 A in einem Ausführungsbeispiel gezeigt.It is known to use such a rollable protective film as a film roller blind for protection against the sun, heat, UV rays and as a privacy screen for windows, shop windows, glass partitions, glass doors, conservatory glazing, etc. Protective films of this type have a flat and smooth surface structure and can optionally be metal-coated. A protective film can consist of several layers with different properties, so that the protection can be individually tailored to the respective application. Such film blinds can be used, for example, as daylight filters against UV rays and glare. If protection is no longer necessary or desired, the original condition can be restored without restriction by rolling up the film. In order to make the film easy to roll, the protective film is made relatively thin. As a result, however, there is no longer sufficient torsional and flexural rigidity and the film tends, particularly in the case of large-area training, to bowl or bulge the surface, as a result of which the appearance and reflection image of the protective film is no longer uniform and harmonious. Such a roll film is shown in US 4 202 395 A in one embodiment.

Aus der DE 37 43 538 A1 ist ein Rolladen mit mehreren Folien bekannt. Dabei werden die Folien zusammen mit einem konventionellen Rolladen auf- und abgerollt, wobei im entrollten Zustand ein Luftpolster zwischen den einzelnen beabstandet angeordneten Folien als zusätzliche Wärmedämmung dient. Versteifungen für die Folien sind keine vorgesehen.A roller shutter with several foils is known from DE 37 43 538 A1. The films are rolled up and down together with a conventional roller shutter, with an air cushion between the individual spaced films serving as additional thermal insulation in the unrolled state. There are no stiffeners for the foils.

Weiters ist aus der EP 0 019 140 A2 ein Rolladen für Möbel bekannt, der aus einer rollfähigen Schichtstoffplatte mit rückseitig quer zur Aufrollrichtung angeordneten Querversteifungen besteht. Die Querversteifungen werden durch eine Prägungen in Form von Rillen, Rippen oder Wülsten aufweisende Folie gebildet. Abgesehen vom relativ hohen Fertigungsaufwand hat ein derartiger Rolladen mit steifen Prägungen den Nachteil eines hohen Platzbedarfes im aufgerollten Zustand, weshalb er für größere Flächen wie Verglasungen nur beschränkt geeignet ist.Furthermore, a roller shutter for furniture is known from EP 0 019 140 A2, which consists of a rollable laminated board with transverse reinforcements arranged on the back transversely to the rolling direction consists. The cross stiffeners are formed by an embossing in the form of grooves, ribs or beads having foil. In addition to the relatively high production costs, such a roller shutter with rigid embossing has the disadvantage of requiring a large amount of space when rolled up, which is why it is of limited use for larger areas such as glazing.

Ferner ist aus der US 4 202 395 A in einem anderen Ausführungsbeispiel eine nicht rollbare, aus einer plissierten Folie bestehende Folienjalousie bekannt. Mittels zumindest zweier Seile kann die Folienjalousie wie ein Faltenbalg zur Deaktivierung aufgezogen und gefaltet bzw. zur Aktivierung entfaltet werden. Der Abstand der Falten wird dabei durch den Platzbedarf im gefalteten Zustand der Folienjalousie bestimmt und beträgt mindestens etwa 2,5 cm. Eine derartige Faltjalousie hat mehrere Nachteile. Zum einen ist die Materialbeanspruchung durch das ständige Falten und Entfalten höher als bei einer Rollo. Zum anderen ist der Abstand zwischen den einzelnen Falten zu groß um eine wirksame Versteifung gegen Beulen der Folie bilden zu können. Eine Verkleinerung der Abstände würde sich aber negativ auf die Faltbarkeit und auf den Platzbedarf im gefalteten Zustand auswirken. Für die Betätigungsseilzüge der Jalousie sind bei anderen bekannten Folienjalousien eine Anzahl von Durchbrüchen der Folie erforderlich, wodurch die Gefahr der Fremdlichteinstrahlung im entfalteten Zustand gegeben ist. Um die Faltung der Folie zu ermöglichen beträgt der Faltwinkel wegen der Steifheit des Kunststoffmaterials auch im entfalteten Zustand über 90°. Derartig große Faltwinkel verhindern die Rollbarkeit der Folie. Im Gegensatz zu einer Folienrollo ist eine Folienjalousie im deaktivierten Zustand gegen Verschmutzung kaum geschützt und hat meist höheren Platzbedarf. Anregungen für einen Fachmann, die Rollfolie zu plissieren oder die Folienjalousie rollbar auszuführen, sind der US 4 202 395 A nicht zu entnehmen.Furthermore, from US 4 202 395 A, in another exemplary embodiment, a non-rollable film blind consisting of a pleated film is known. Using at least two ropes, the film blind can be pulled up and folded like a bellows for deactivation or unfolded for activation. The distance between the folds is determined by the space required in the folded state of the film blind and is at least about 2.5 cm. Such a folding blind has several disadvantages. On the one hand, the material stress due to the constant folding and unfolding is higher than with a roller blind. On the other hand, the distance between the individual folds is too large to be able to form an effective stiffening against bulging of the film. A reduction in the spacing would have a negative impact on the foldability and the space requirement in the folded state. In the case of other known film blinds, a number of breakthroughs in the film are required for the actuating cable pulls of the blind, as a result of which there is a risk of extraneous light radiation when unfolded. In order to allow the film to be folded, the folding angle is more than 90 ° even when unfolded because of the stiffness of the plastic material. Such large folding angles prevent the film from being rolled. In contrast to a film roller blind, a film blind in the deactivated state is hardly protected against dirt and usually requires more space. US Pat. No. 4,202,395 A does not contain any suggestions for a person skilled in the art to pleat the roll film or to make the film blind rollable.

Aufgabe der Erfindung ist es, diese Nachteile zu vermeiden und eine auf Schüsseln bzw. Beulen unempfindliche rollbare Schutzfolie zu schaffen.The object of the invention is to avoid these disadvantages and to create a rollable protective film which is insensitive to bowls or bumps.

Erfindungsgemäß wird dies dadurch erreicht, daß die Schutzfolie eine Vielzahl von etwa parallel zur Rollachse angeordnete, sich über die gesamte Folienbreite erstreckende gleichmäßig beabstandete Versteifungen aufweist, wobei die Versteifungen durch mittels Plissieren der Schutzfolie permanent vorgeformte Falten gebildet sind. Dadurch wird das Widerstandsmoment der Folie normal zu den Versteifungen erhöht, während weiterhin ein unbehindertes Auf- und Entrollen der Schutzfolie möglich ist.According to the invention, this is achieved in that the protective film has a plurality of uniformly spaced stiffeners which are arranged approximately parallel to the roll axis and extend over the entire film width, the stiffeners are formed by pleats of the protective film permanently pre-formed. As a result, the section modulus of the film is increased normally to the stiffeners, while the protective film can still be rolled on and off unimpeded.

Durch das Plissieren der Schutzfolie wird eine besonders einfache Herstellung der Versteifungen ermöglicht. Im Gegensatz zu Faltjalousien erfolgt nur eine Vorfaltung beim Plissieren der Schutzfolie. Während des Einsatzes der Schutzfolie erfolgt dagegen keine Faltung mehr. In einer sehr vorteilhaften Ausführungsform besteht die Schutzfolie zumindest überwiegend aus Polyester. Durchsichtige Rollofolien aus Polyestermaterial zu fertigen ist beispielsweise aus der DE 36 02 954 A1 bekannt. Beim Plissieren der Polyesterfolie erfolgt eine plastische Formänderung im molekularen Bereich, welche während der gesamten Lebensdauer der Schutzfolie erhalten bleibt.The pleating of the protective film enables a particularly simple manufacture of the stiffeners. In contrast to pleated blinds, the protective film is only pre-folded. On the other hand, there is no folding when the protective film is used. In a very advantageous embodiment, the protective film consists at least predominantly of polyester. It is known, for example, from DE 36 02 954 A1 to produce transparent roller films from polyester material. When pleating the polyester film, there is a plastic change in shape in the molecular range, which is retained throughout the life of the protective film.

Um eine effektive Versteifung der Schutzfolie zu erreichen ist es besonders vorteilhaft, wenn der Abstand zwischen zwei benachbarten Versteifungen zwischen 5 mm und 20 mm, vorzugsweise zwischen 7 mm und 14 mm beträgt. Bei größerem Abstand ist die nötige Versteifung der Folie unzureichend, und die Rollfähigkeit wird verschlechtert, bei kleinerem Abstand wird die Lichtdurchlässigkeit der Folie zu sehr vermindert.In order to achieve an effective stiffening of the protective film, it is particularly advantageous if the distance between two adjacent stiffeners is between 5 mm and 20 mm, preferably between 7 mm and 14 mm. At a greater distance, the necessary stiffening of the film is inadequate and the rollability is impaired, at a smaller distance the transparency of the film is reduced too much.

Die Erfindung wird anhand der Figuren näher erläutert. Es zeigen:The invention is explained in more detail with reference to the figures. Show it:

Die Schutzfolie 1 ist um die Rollachse 1' auf- bzw. abrollbar befestigt. Die Schutzfolie 1 weist in regelmäßigen Abständen durch Plissieren gebildete Falten 3 auf, welche Versteifungen 2 über die gesamte Breite B der Schutzfolie 1 bilden. Die etwa parallel zur Rollachse 1' der Rolle 4 ausgerichteten Versteifungen 2 sind jeweils voneinander in einem Abstand b zwischen 5 und 20 mm, vorzugsweise in einem Bereich zwischen 7 und 14 mm beabstandet. Größere Abstände als die angegebenen verschlechtern die Rollfähigkeit der Schutzfolie 1, geringere Abstände wirken sich negativ auf das Erscheinungs- und Reflexionsbild der Schutzfolie 1 aus. Die durch die Vorfaltung entstehenden Faltwinkeln α zwischen zwei an einer Falte 3 benachbarten Folienabschnitte 1a und 1b verbessert die spezifische Reflexion der Infrarotstrahlen. Sowohl im entrollten als auch im aufgerollten Zustand betragen die Faltwinkeln α unter 30°, meist etwa 15°, wodurch einerseits eine gute Rollbarkeit und andererseits eine ausreichende Versteifung gegeben ist. Am Anfangsbereich der Schutzfolie 1 ist an dieser ein Abschlußstab 5 befestigt, welcher die Schutzfolie 1 durch sein Eigengewicht stabilisiert.The protective film 1 is fastened so that it can be rolled up or unrolled around the roll axis 1 '. The protective film 1 has pleats 3 formed at regular intervals by pleating, which form stiffeners 2 over the entire width B of the protective film 1. The stiffeners 2, which are oriented approximately parallel to the roll axis 1 'of the roll 4, are each spaced from one another at a distance b between 5 and 20 mm, preferably in a range between 7 and 14 mm. Larger distances than the specified deteriorate the rolling ability of the protective film 1, smaller distances have a negative effect on the appearance and reflection image of the protective film 1. The folding angles α resulting from the pre-folding between two film sections 1a and 1b adjacent to a fold 3 improve the specific reflection of the infrared rays. Both in the unrolled and in the rolled-up state, the folding angles α are below 30 °, usually about 15 °, which on the one hand gives good rollability and on the other hand provides sufficient stiffening. At the beginning of the protective film 1, an end rod 5 is attached to it, which stabilizes the protective film 1 by its own weight.

Die Schutzfolie 1 kann aus mehreren Folienschichten bestehen und auch metallbeschichtet sein, wodurch individuell die Wellenlänge der durchgelassenen und reflektierten Strahlung sowohl im sichtbaren als auch im nicht sichtbaren Bereich eingestellt werden kann. Die Dicke der Schutzfolie 1 kann von etwa 0.02 mm für eine Folienschicht bis zu etwa 0,6 mm bei mehreren Folienschichten betragen.The protective film 1 can consist of several film layers and can also be metal-coated, as a result of which the wavelength of the transmitted and reflected radiation can be set individually both in the visible and in the non-visible range. The thickness of the protective film 1 can be from approximately 0.02 mm for one film layer to approximately 0.6 mm for several film layers.
