Abstract

The marker has elongated segments having a light module (12) arranged on a carrier module (10). The light module has a transparent plastic material, in which photoluminescence pigments e.g. strontium aluminate, dysprosium oxide and europiumoxide, are mixed. The pigments glow in a dark, and are microscopically encapsulated in another material e.g. plastic material, glass or silicate, which is different from the transparent plastic material, such that liquid and moisture do not come in contact with the pigments.

Description

Die vorliegende Erfindung betrifft eine Fluchtwegmarkierung für ein Flugzeug.The present invention relates to an escape route marking for an aircraft.

Es ist bekannt in Flugzeugen zur Fluchtwegmarkierung, die auch als Notfallmarkierung bezeichnet wird, photolumineszente Streifen am Fußboden im Passagierraum des Flugzeugs anzuordnen. Photolumineszenz wird gelegentlich auch als Nachleuchten und/oder Phosphorisieren bezeichnet. Die sicherheitstechnischen Anforderungen für die Fluchtwegmarkierung sind beispielsweise in der Deutschen Industrie Norm DIN 67 510 spezifiziert. Die Streifen werden geradlinig im Fußboden verlegt und weisen den Passagieren und der Besatzung im Notfall den Weg zu den Ausgängen und Notausstiegen. In der Vergangenheit haben sich bei der Ausgestaltung von Flugzeugen zunehmend photolumineszente Streifen durchgesetzt, da diese ohne Stromversorgung betrieben werden können und bei den heute zur Verfügung stehenden Pigmenten ausreichend lange und hell im Dunkeln nachleuchten.It is known in aircraft for escape route marking, which is also referred to as emergency marking, to arrange photoluminescent strips on the floor in the passenger compartment of the aircraft. Photoluminescence is sometimes referred to as afterglow and / or phosphorizing. The safety requirements for the escape route marking are specified, for example, in the German industrial standard DIN 67 510. The strips are laid in a straight line in the floor and show the passengers and the crew in an emergency the way to the exits and emergency exits. In the past, photoluminescent strips have become increasingly prevalent in the design of aircraft, since they can be operated without a power supply and, in the case of the pigments available today, luminesce sufficiently long and brightly in the dark.

Aus WO 96/33093 A1 ist beispielsweise eine Notfallbeleuchtung bekannt, bei der ein photolumineszenter Streifen in einen transparenten Kunststoff eingebracht sind. Als Farbstoffe für das photolumineszente Material werden Xylen, 2-Butoxyethanol und Cyolohexanon eingesetzt.Out WO 96/33093 A1 For example, emergency lighting is known in which a photoluminescent strip is incorporated in a transparent plastic. As dyes for the photoluminescent material xylene, 2-butoxyethanol and cyolohexanone are used.

Aus WO 94/17766 A1 ist eine photolumineszente Reflektorschicht bekannt, bei der phosphorisierende Pigmente durch Siebdruck in Mustern auf eine Unterlage aufgebracht werden.Out WO 94/17766 A1 a photoluminescent reflector layer is known in which phosphorescent pigments are applied by screen printing in patterns on a substrate.

Aus US 4,401,050 ist eine photolumineszente Fluchtwegmarkierung bekannt, bei der das photoluminiszente Material auf die Rückseite einer Lage eines Flachmaterials aus Kunststoff aufgebracht wird.Out US 4,401,050 For example, a photoluminescent escape route marker is known in which the photoluminescent material is applied to the back surface of a sheet of plastic sheet.

Aus WO 87/02813 A1 sind Richtungsanzeiger für den Fluchtweg bekannt, bei dem photolumineszente Mittel durch Sprühen oder Siebdruck auf ein Trägermaterial aufgebracht werden.Out WO 87/02813 A1 For example, directional displays are known for the escape route, in which photoluminescent agents are applied to a carrier material by spraying or screen printing.

Aus EP 0 489 561 A1 ist eine dauerhaft fluoreszierende Lage bekannt, bei der Farbpigmente in eine Polymermatrix eingebunden sind. Hierbei kann das fluoreszente Material in einem Träger eingebunden sein, der dem Fluoreszenslicht durch zusätzliche Filter verschiedene optische Eigenschaften verleiht.Out EP 0 489 561 A1 is a permanently fluorescent layer known in which color pigments are incorporated into a polymer matrix. In this case, the fluorescent material may be incorporated in a carrier which imparts different optical properties to the fluorescent light through additional filters.

Aus FR 2 308 155 A1 sind mit photolumineszentem Material hinterlegte Sicherheitsschilder bekannt, bei denen eine Dispersion mit photolumineszenten Pigmenten auf eine transparente Schicht aus Kunststoffmaterial aufgebracht wird.Out FR 2 308 155 A1 are security signs deposited with photoluminescent material, in which a dispersion with photoluminescent pigments is applied to a transparent layer of plastic material.

Bei der Anwendung bekannter Fluchtwegmarkierungen, ist immer wieder das Problem aufgetreten, das Stellen der Markierung nach einem Verlegen der Fluchtwegmarkierung ihre Leuchtkraft und/oder ihre Farbe verlieren.When using known escape route markers, there has always been the problem that the marking stops after the escape route marker has been emptied and loses its luminosity and / or color.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Fluchtwegmarkierung bereitzustellen, die sich mit einfachen Mitteln dauerhaft im Passagierraum eines Flugzeugs einsetzen läßt.The present invention has for its object to provide an escape route marking, which can be used with simple means permanently in the passenger compartment of an aircraft.

Erfindungsgemäß wird die Aufgabe durch eine Fluchtwegmarkierung mit den Merkmalen aus Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen bilden die Gegenstände der Unteransprüche.According to the invention the object is achieved by an escape route marking with the features of claim 1. Advantageous embodiments form the subject of the dependent claims.

Die erfindungsgemäße Fluchtwegmarkierung ist für den Passagierraum eines Flugzeugs geeignet. Die Fluchtwegmarkierung weist eine Vielzahl von länglichen Segmenten auf, die hintereinander entlang dem zu markierenden Fluchtweg auf dem Untergrund angeordnet sind. Die länglichen Elemente können eine beliebige Form besitzen, insbesondere auch einen geradlinigen oder einen gebogenen Verlauf. Jedes Segment weist ein Trägermodul und ein Leuchtmodul auf. Das Leuchtmodul ist auf dem Trägermodul angeordnet. Das Leuchtmodul besteht aus einem im wesentlichen transparenten Kunststoffmaterial, in das photolumineszente Pigmente eingearbeitet sind, die das gewünschte Nachleuchten im Dunkeln erzeugen.The escape route marking according to the invention is suitable for the passenger compartment of an aircraft. The escape route marking has a multiplicity of elongated segments, which are arranged one behind the other along the escape route to be marked on the underground. The elongated elements may have any shape, in particular a straight or a curved course. Each segment has a carrier module and a light module. The light module is arranged on the carrier module. The light module consists of a substantially transparent plastic material, in which photoluminescent pigments are incorporated, which produce the desired afterglow in the dark.

Erfindungsgemäß sind die Pigmente in einem zweiten Material mikroskopisch gekapselt derart, daß Flüssigkeit und Feuchtigkeit nicht in Kontakt mit den Pigmenten gelangen können. Die Pigmente sind vollständig in das zweite Material eingekapselt.According to the invention, the pigments are microscopically encapsulated in a second material such that liquid and moisture can not get in contact with the pigments. The pigments are completely encapsulated in the second material.

Das Material für die Verkapselung ist von dem Kunststoffmaterial, in das die gekapselten Pigmente eingearbeitet sind, verschieden.The material for the encapsulation is different from the plastic material into which the encapsulated pigments are incorporated.

Der Erfindung liegt die Erkenntnis zugrunde, daß die fehlende Leuchtkraft oder das Nachdunkeln der Leuchtmodule, das sich beispielsweise auch in braunen oder schwarzen Flecken äußern kann, auf Flüssigkeit und/oder Feuchtigkeitsdampf zurückzuführen sind, die im Laufe der Zeit eine chemische Reaktion der Pigmente auslösen, in deren Folge eine Braunfärbung, sogenannte Pigmentkorrosion, eintritt. Durch eine mikroskopische Kapselung der Pigmente ist sichergestellt, daß auch im Laufe der Zeit die Pigmente nicht korrodieren und damit nicht an Leuchtkraft verlieren. Auch besteht ein besonderer Vorteil der erfindungsgemäßen Fluchtwegmarkierung darin, daß das Leuchtmodul geschnitten werden kann, ohne daß die Schnittfläche korrodieren kann.The invention is based on the finding that the lack of luminosity or the darkening of the light modules, which can manifest themselves, for example, in brown or black spots, are due to liquid and / or moisture vapor which, over time, trigger a chemical reaction of the pigments, as a result, a brown color, so-called pigment corrosion, occurs. Microscopic encapsulation of the pigments ensures that the pigments do not corrode over time and therefore do not luminesce to lose. Also, a particular advantage of the escape route marking according to the invention is that the light module can be cut without the cut surface can corrode.

Bei dem zweiten Material handelt es sich bevorzugt um ein Kunststoffmaterial.The second material is preferably a plastic material.

Für das zweite Material kann auch ein Silicat oder ein Glas eingesetzt werden.For the second material, a silicate or a glass can also be used.

Das transparente Kunststoffmaterial des Leuchtmoduls besitzt eine Stärke von 0,1 bis 2,0 mm, bevorzugt wird das transparente Kunststoffmaterial mit einer Stärke von 0,2 bis 1,5 mm hergestellt. Das transparente Kunststoffmaterial bildet eine Matrix, in der die mikrogekapselten Pigmente in einer vorzugsweise gleichmäßigen Verteilung gehalten sind.The transparent plastic material of the light module has a thickness of 0.1 to 2.0 mm, preferably the transparent plastic material is produced with a thickness of 0.2 to 1.5 mm. The transparent plastic material forms a matrix in which the microencapsulated pigments are maintained in a preferably uniform distribution.

In einem bevorzugten Herstellungsverfahren wird das transparente Kunststoffmaterial gemeinsam mit den Pigmenten extrudiert. Alternativ ist es auch möglich, das transparente Kunststoffmaterial mit den Pigmenten auf das Trägermodul zu drucken, bevorzugt wird hierbei ein Siebdruck eingesetzt. In einer alternativen Ausgestaltung ist es ebenfalls möglich, das transparente Kunststoffmaterial zu einem Leuchtmodul zu gießen, wobei die mikrogekapselten Pigmente dabei ebenfalls mit vergossen werden.In a preferred manufacturing process, the transparent plastic material is extruded together with the pigments. Alternatively, it is also possible to print the transparent plastic material with the pigments on the carrier module, preferably a screen printing is used here. In an alternative embodiment, it is also possible to cast the transparent plastic material to a light emitting module, wherein the microencapsulated pigments are also cast with it.

Ebenfalls ist es möglich, das transparente Kunststoffmaterial gemeinsam mit den Pigmenten auf das Trägermodul zu spritzen und dort erstarren zu lassen.It is also possible to spray the transparent plastic material together with the pigments onto the carrier module and allow it to solidify there.

In einer bevorzugten Ausgestaltung werden photolumineszente Pigmente eingesetzt, die Strontiumaluminat enthalten. Diese Pigmente lassen sich in lösungsmittelhaltigen Lacken, Druckfarben, Thermo- und Druckpaste und Plastisole verarbeiten. Für die Kapselung der Pigmente eignen sich insbesondere Polypropylen und Polyethylen. Das Material kann weiter aufpolymerisiert sein, insbesondere um die gewünschte Mikroverkapselung zu erzielen. Beispielsweise kann ein Maleinanhydrid gepfropftes Polypropylen zur Verkapselung eingesetzt werden. Es sind auch weitere Kunststoffmaterialien, die eine ausreichende Mikroverkapselung der Pigmente bereitstellen möglich.In a preferred embodiment, photoluminescent pigments are used which contain strontium aluminate. These pigments can be processed in solvent-based paints, printing inks, thermal and printing paste and plastisols. Polypropylene and polyethylene are particularly suitable for the encapsulation of the pigments. The material may be further grafted on, in particular to achieve the desired microencapsulation. For example, a maleic anhydride grafted polypropylene can be used for encapsulation. There are also other plastic materials that provide sufficient microencapsulation of the pigments possible.

Die verkapselten Pigmente werden in dem fertigen Leuchtmodul in die Polymermatrix des ersten Kunststoffmaterials eingelagert.The encapsulated pigments are incorporated in the finished light module in the polymer matrix of the first plastic material.

Figur 1 zeigt ein Trägermodul 10, das eine quaderförmige Form besitzt und als ein länglicher Streifen ausgebildet ist. Das Trägermodul besteht aus einem Kunststoff und kann mit dem Boden des Passagierraums beispielsweise verklebt oder verschraubt sein. Dabei ist es nicht unbedingt notwendig, daß das Trägermodul einen geraden Verlauf besitzt, auch kann das Trägermodul bzw. die gesamte Fluchtwegmarkierung einen gebogenen Verlauf besitzen. FIG. 1 shows a carrier module 10 which has a cuboid shape and is formed as an elongated strip. The carrier module is made of a plastic and may be glued or screwed to the floor of the passenger compartment, for example. It is not absolutely necessary that the carrier module has a straight course, also the carrier module or the entire escape route marking may have a curved course.

Auf dem Trägermodul 10 angeordnet ist ein Leuchtmodul 12. Hierbei kann das Leuchtmodul 12 beispielsweise auf das Trägermodul 10 geklebt sein. Auch ist es möglich das Leuchtmodul 12 anderweitig mit dem Trägermodul 10 zu verbinden. Beispielsweise kann das Leuchtmodul 12 auf das Trägermodul extrudiert werden oder durch Siebdruck aufgebracht werden. Die Dicke d des Leuchtmoduls beträgt ungefähr 0,2 mm bis 1,5 mm.Arranged on the carrier module 10 is a lighting module 12. In this case, the lighting module 12 can be glued onto the carrier module 10, for example. It is also possible to connect the light module 12 otherwise with the carrier module 10. For example, the light module 12 can be extruded onto the carrier module or applied by screen printing. The thickness d of the light module is about 0.2 mm to 1.5 mm.

Das Leuchtmodul 2 besteht aus einem transparenten Kunststoffmaterial (Binder) in das mikroverkapselte photolumineszente Pigmente eingearbeitet sind.

Unterhalb des Leuchtmoduls 14 sind Vorsprünge 20 vorgesehen, die sich in Längsrichtung des Trägermoduls erstrecken und die zu einer besseren Verklebung mit dem Untergrund dienen. Abgedeckt ist das Trägermodul mit einer U-förmigen Abdeckschiene 22, die aus einem transparenten Material besteht und einen Trittschutz für das Leuchtmodul 16 bildet. Die Trägerschiene 22 besitzt Seitenwände 24 mit einer an ihrem Ende jeweils vorspringenden Nase 26, die jeweils einen Vorsprung an den Seitenwänden 18 hintergreifen. FIG. 2 shows an alternative construction of an escape route marker in cross section, in which a light-emitting module 16 is arranged in a carrier module 14. The carrier module 14 has in its cross-section lateral boundary walls 18, which form a trough-shaped receiving space for the light-emitting module 16. Below the light-emitting module 14, projections 20 are provided which extend in the longitudinal direction of the carrier module and which serve for better bonding to the substrate. Covered is the carrier module with a U-shaped cover rail 22, which consists of a transparent material and forms a step protection for the light-emitting module 16. The carrier rail 22 has side walls 24 with a nose 26 projecting at its end, each of which engages behind a projection on the side walls 18.
