Description

Die Erfindung betrifft eine rollbare Schutzfolie aus Kunststoff für Verglasungen, wobei die Schutzfolie eine Vielzahl von etwa parallel zur Rollachse angeordnete, sich über die gesamte Folienbreite erstreckende, durch permanent vorgeformte Falten gebildete Versteifungen aufweist, wobei die Falten durch einen einen Vorfaltungsschritt aufweisenden Plissiervorgang der Schutzfolie gebildet sind und die Schutzfolie aus abwechselnd in einem stumpfen Winkel zueinander geneigten und im Bereich jeweils einer Falte aneinander grenzenden Folienabschnitten besteht, und wobei jeder Folienabschnitt durch eine ebene Fläche gebildet ist.The invention relates to a rollable protective film made of plastic for glazing, the protective film a variety of about arranged parallel to the roll axis, over the entire width of the film extending, formed by permanently pre-formed folds Has stiffeners, the folds by a a pleating process comprising a pre-folding step Protective film are formed and the protective film alternately at an obtuse angle to each other and in the area there is a fold of adjacent film sections, and each section of film through a flat surface is formed.

Es ist bekannt, eine 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-A-4 202 395 in einem Ausführungsbeispiel gezeigt.It is known to use a rollable protective film as a film roller blind Protection against sun, heat, UV rays and as a privacy screen for windows, shop windows, glass partitions, glass doors, conservatory glazing, etc. to use. Such protective films have a flat and smooth surface structure and can if necessary, be metal-coated. A protective film can be made from each several layers with different properties exist, making protection individual for each Use case can be coordinated. Such film blinds can, for example, as daylight filters against UV rays and glare can be used. Protection is no longer necessary or desired, the original can be rolled up Condition can be restored without restriction. To enable the film to roll well, the Protective film is relatively thin. This is, however there is no longer sufficient torsional and flexural rigidity and the film tends, especially in the case of large-area training, for so-called bowls or dents on the surface, which creates the appearance and reflection of the protective film is no longer even and harmonious. Such a roll film is in one embodiment in US-A-4 202 395 shown.

Die DE-A-30 45 883 beschreibt eine als äußerer Vorhang bei einem Fenster dienende Jalousie aus Metall oder Kunststoff, mit einer Schutzfolie der eingangs genannten Art welche auf einer profilierten Wickelwelle aufrollbar ist, wobei die Profilierung durch Zähne gebildet wird. Die Folie weist eine der Profilierung angepaßte Zick-Zack-förmige Faltung unter Bildung von miteinander verbundenen Falten auf, die in Intervallen mit unterschiedlichen, von oben nach unten zunehmenden Breitenabmessungen ausgebildet sind. Dadurch weist die Jalousie in Bereichen mit größeren Abständen zwischen den Falten eine geringere Steifigkeit auf. Die unterschiedlichen Abstände erhöhen darüber hinaus den Herstellungsaufwand. Die profilierte Wickelwelle bedingt auch relativ große Faltwinkel, wodurch einerseits die Durchsicht stark eingeschränkt ist und andererseits Infrarotstrahlen nur ungenügend reflektiert werden. Die profilierte Wickelwelle sowie die großen Faltwinkel bedingen einen relativ hohen Platzbedarf.DE-A-30 45 883 describes one as an outer curtain a window blind made of metal or plastic, with a protective film of the type mentioned which on a profiled winding shaft can be rolled up, the profiling is formed by teeth. The film has one of the profiles customized zigzag folding to form interconnected folds that appear at intervals with different, Width dimensions increasing from top to bottom are trained. As a result, the blind points in areas with larger gaps between the folds, a smaller one Stiffness. The different distances increase above addition, the manufacturing effort. The profiled winding shaft conditionally also relatively large folding angles, which on the one hand makes the Visibility is severely restricted and on the other hand infrared rays are reflected insufficiently. The profiled Winding shaft and the large folding angle require a relative high space requirement.

Aus der BE-A-883 661 ist eine Vorrichtung zur Wärmeisolation mit einer rollbaren Folie bekannt, welche zur Versteifung voneinander beabstandete Faltungen aufweist. Jede Faltung ist dabei als V-förmige, zurückspringende Furche von geringer Tiefe ausgebildet und wird durch Rollen von Rädchen von geeignetem Querschnitt quer zur Folie erzeugt. Der Versteifungseffekt durch die Furchen und somit der Schutz gegen Schüsseln und Beulen ist allerdings geringer als bei Falten, welche durch einen einen Vorfaltungsschritt aufweisenden Plissiervorgang gebildet werden.From BE-A-883 661 is a device for thermal insulation known with a rollable film, which used to stiffen each other spaced folds. Every fold is there as a V-shaped, recessed furrow of shallow depth trained and is made by rolling cogs of suitable Cross-section created across the film. The stiffening effect through the furrows and thus protection against bowls and dents is, however, less than for wrinkles caused by a a pleating process comprising a pre-folding step will.

Aus der DE-A-37 43 538 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.From DE-A-37 43 538 is a roller shutter with several films known. The slides are used together with a conventional one Roller shutters rolled up and down, in the unrolled state an air cushion between the individual spaced apart Foils serve as additional thermal insulation. Stiffeners for the slides are not provided.

Weiters ist aus der EP-A-0 019 140 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-A-0 019 140, the one made of a rollable laminate with the back Cross stiffeners arranged transversely to the winding direction consists. The cross stiffeners are embossed in Form formed by grooves, ribs or beads film. Apart from the relatively high manufacturing effort, such a Roller shutters with stiff embossing have the disadvantage of a high one Requires space when rolled up, which is why it is for larger Areas such as glazing are only suitable to a limited extent.

Ferner ist aus der US-A-4 202 395 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-A-4 202 395 nicht zu entnehmen.Furthermore, from US-A-4 202 395 in another embodiment a not rollable, from a pleated film existing film blind known. By means of at least two Ropes can be used to deactivate the film blind like a bellows wound and folded or unfolded for activation will. The distance between the folds is determined by the space required determined and in the folded state of the film blind at least about 2.5 cm. Such a folding blind has several Disadvantage. On the one hand, the material stress is caused by the constant folding and unfolding higher than with a roller blind. To the others the distance between the individual folds is too large to form an effective stiffening against buckling of the film can. A reduction in the distances would be negative on the foldability and on the space required in the folded Condition. For the operating cables of the blind are a number of other known film blinds Breakthroughs in the film required, increasing the risk of External light radiation in the unfolded state is given. Around To enable the film to fold is the folding angle because of the stiffness of the plastic material also in the unfolded Condition over 90 °. Such large folding angles prevent that Rollability of the film. In contrast to a foil roller blind a foil blind in the deactivated state against Pollution hardly protected and usually takes up more space. Suggestions for a specialist to pleat the roll film or to make the film blind rollable are US-A-4 202 395 not to be removed.

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 a rollable protective film that is insensitive to bowls or dents to accomplish.

Erfindungsgemäß wird dies dadurch erreicht, daß die Falten der vorzugsweise aus mehreren Folienschichten bestehenden Schutzfolie gleichmäßig voneinander beabstandet sind, und daß der zwischen einem Folienabschnitt und einer durch den benachbarten Folienabschnitt verlaufenden Ebene gemessene Faltungswinkel sowohl im entrollten als auch im aufgerollten Zustand unter 30°, vorzugsweise etwa 15°, beträgt. Dadurch wird das Widerstandsmoment der Folie normal zu den Versteifungen erhöht, während weiterhin ein unbehindertes Auf- und Entrollen der Schutzfolie möglich ist. Die relativ kleinen Faltenwinkel ermöglichen eine hohe spezifische Reflexion von Infrarotstrahlen und haben weiters den Vorteil, daß die Schutzfolie, sowohl im entrollten, als auch im aufgerollten Zustand wenig Platz benötigt.According to the invention this is achieved in that the folds of the preferably protective film consisting of several film layers are evenly spaced from each other, and that the between one film section and one through the adjacent one Plane section extending plane measured folding angle both in the unrolled as well as in the rolled state under 30 °, preferably about 15 °. This creates the section modulus the film increased normal to the stiffeners while continuing unrestricted rolling up and unrolling of the protective film is possible. The relatively small fold angles allow one high specific reflection of infrared rays and also have the advantage that the protective film, both when unrolled, and also requires little space when rolled up.

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.Pleating the protective film makes it particularly easy Production of stiffeners enables. In contrast to Folded blinds are only pre-folded when pleating the Protective film. However, while the protective film is in use no more folding. In a very advantageous embodiment the protective film consists at least predominantly of polyester. See-through roller blinds made of polyester material too Manufacturing is known for example from DE 36 02 954 A1. When pleating the polyester film, there is a plastic one Shape change in the molecular area, which during the entire The lifespan of the protective film is preserved.

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.To achieve an effective stiffening of the protective film it is particularly advantageous if the distance between two neighboring ones Stiffeners between 5 mm and 20 mm, preferably is between 7 mm and 14 mm. If the distance is greater, the necessary stiffening of the film is insufficient, and the ability to roll is deteriorated, at a smaller distance the light transmission becomes the film is reduced too much.

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 can be rolled up or unrolled around the roll axis 1 ' attached. The protective film 1 points at regular intervals folds 3 formed by pleating, which stiffeners 2 Form over the entire width B of the protective film 1. The approximately Stiffeners aligned parallel to the roll axis 1 'of the roll 4 2 are each at a distance b between 5 and 20 mm, preferably in a range between 7 and 14 mm apart. Distances greater than the specified deteriorate the rollability of the protective film 1, shorter distances have a negative effect on the appearance and reflection the protective film 1. The resulting from the pre-folding Folding angles α between two neighboring folds 3 Foil sections 1a and 1b improve the specific Reflection of infrared rays. Both in the unrolled as well when rolled up, the folding angles α are below 30 °, mostly about 15 °, which on the one hand makes it easy to roll and on the other hand there is sufficient stiffening. At the beginning the protective film 1 is a final rod 5 on this attached, which the protective film 1 by its own weight stabilized.

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 also be metal-coated, which makes the wavelength individual the transmitted and reflected radiation both set in the visible as well as in the non-visible area can be. The thickness of the protective film 1 can be about 0.02 mm for one film layer up to about 0.6 mm with several film layers be.
