Lamellar ground marking

#The invention relates to a lamellar or strip-shaped floor marking, in particular for means of transportation, very particularly for airplanes, having a photoluminescent layer on which covering elements which appear dark in comparison with the luminous layer and which serve as a directional indication are arranged in such a way that acute-angled markings pointing in a direction are formed.

#It is known to affix lamellar or strip-shaped floor markings having a photoluminescent layer in airplanes. By means of daylight or the illumination in the airplane cabin, the photoluminescent layer is made to glow. This glow continues for a long period of time when the floor marking is no longer being illuminated. In the case of an accident, airplane passengers can orient themselves even in darkness by means of these glowing floor markings. An external illumination, which is complex and fault-prone, is not required.

#These floor markings indicate escape routes. In this case there are also no particular problems if the airplane, as is conventional, is provided with emergency exits at the front and rear end of the airplane cabin (and usually also over the wings). In that case, it is not necessarily a matter of finding the nearest emergency exit in the case of an accident but rather, led by the glowing floor markings, of following the other passengers to the nearest exit. However, it is a different proposition if the airplane has a so-called “dead end”, that is to say if, for example, no emergency exit is provided at the rear end. There is then the danger that in the case of an accident passengers follow the floor markings in the wrong direction, namely to the end of a cabin not provided with an emergency exit. In order to avoid this, it is known to affix opaque markings in triangular form on the floor markings, the tip of the triangle pointing in the direction of the escape route. Such dark markings can be created by applying a coating, for example. The applied coating on the one hand prevents the photoluminescent layer underneath from being “charged” by incident light. On the other hand, light that is nevertheless emitted therefrom is absorbed by the markings. These markings usually have a distance between them of approximately 50 cm. A closer distance is clearly considered not to be expedient, because in this case there is no longer enough glowing surface of the floor marking available.

#Advantageous embodiments are described in an exemplary manner below with reference to the attached drawings, in which

#FIG. 1 shows the floor marking in a cross section;

#FIG. 2 shows the floor marking in a perspective view with a middle part omitted; and

#As is shown in FIG. 1, the floor marking has an adhesive layer 1, by means of which it can be fixed to the floor. A reflective layer 2, which directs light scattered downward by the luminous layer 3 upward, is located above this layer. The covering elements are arranged in a layer 4. The floor marking is covered by means of a non-slip, possibly also colored polycarbonate layer 5.

#As can be seen from FIG. 2, the covering elements 6 of the layer 4 merge to a point toward the front and have a corresponding triangular recess toward the back.

#In the embodiments of FIGS. 3 and 4 the covering elements 6, indeed likewise have a rear triangular recess by means of which glowing arrows of the uncovered regions 7 of the floor marking are created. At their front end, the covers 6 are bounded by a straight line, so that a picture of an arrow is obtained.
