"Illuminated circuit diagram for illuminated control room."

The invention relates to a luminous circuit diagram for a

People control room with a blackboard made of glass or the like! with a picture layer, consisting of letters i symbols, pictures, colored surfaces and the like, which adheres to the back of the glass plate and with a protective layer that can be easily removed from the back of the plate and with cutouts through all layers at places where light signals should appear “Many of the well-known people still have ali coverage today

on the back an opaque sheet, for example. made of cardboard, which can be easily removed if you want to change something in the actual picture.This is applied directly to the back of the glass plate by gluing, painting or another technique and then covered with the cover.

^ It is also known to apply a matt, colorless and transparent lacquer, which can also be washed off, to the back of the glass plate of a luminous circuit diagram. The smile is applied to the entire back of the glass plate, also where the circuit symbols come or only where the circuit symbols come directly. The circuit symbols are applied to the lacquer, but not directly to the glass plate. The object of the invention is to create the possibility. Parts remove the image from the glass plate and replace it with another without the whole picture needs to be replaced, can not be solved with the known methods and is not intended to solve "The execution of the known light diagram is only the task of certain to achieve optical effects -

According to the invention, it is proposed that the protective layer should be detachably adhered to the back of the image layer.

It is advantageous here if the elements of the image layer are insensitive to chemicals that would be able to dissolve the protective layer.

As an example of the implementation of the ancient idea it is proposed that the protective layer be a self-adhesive film that separates the elements of the image layer easily detachable and self-adhering to it (is, or that it is a liquid to be applied layer for their production a per se known color-like mixture of substances such as pigments, dryers and the like and one (carrier liquid, none of which attacks the elements of the image layer) in the former case can be found where there is a change in the luminous circuit diagram want to make, peel off the self-adhesive film and then replace the picture elements. In the second case, wipe

one the; Protective layer at the relevant point. A danger,; that in this case the adjacent parts of the image layer damaged does not exist if one follows the teachings of the invention.

It is known per se to cut out the characters of a luminous circuit diagram from a package of self-adhesive foils and to apply them to the plate. Together with the image components from the package of self-adhesive films can then the whole surface of the lighting diagram with any sprayed a coating, be · After that attracts you

-S _n "removes the top film from the film package including the paint adhering to it and thus makes the circuit diagram visible. Changes to such a circuit diagram are not possible in the 'simple way * as is done with the invention *

According to the invention, the image layer can also be a printed one Be picture. Another possibility is that the letters and symbols of the picture are wax letters and wax symbols that are to be applied first to the rear surface and that the colored surfaces are conventional Colors are. In addition to the letter symbols, the image layer can have several successive overlapping ones Contain layers of color following the letters and symbols successively on the rear surface of the apple are applied. ;

It is known that recessed areas where light signals should appear are transparent or translucent colored. A colored film can be stuck to the outside of the protective cover on the recessed areas · The protective layer is preferably not impermeable. For the luminous circuit diagrams made without openings Preferably glass, safety or bulletproof glass are used.

In the drawing is an embodiment of the invention shown. There are;

. 1 A view of an illuminated circuit diagram. 2 a broken piece of the illuminated image

after Pig. 1, shown disassembled, Pig. 3 the detail A from Pig. 2, enlarged shown.

Pig. 1 shows the front of the luminous circuit diagram. When viewed from the rear, the luminous circuit diagram shows a uniform monochrome surface

A rope of the plant is made with the help of symbols, letters and colored areas. The symbols 1, 2, 5 and 4 represent a feeding device in this order, a front niche, a drain and a water tank Representation of the process flow arrows C and lines used. Recesses for signal lamps are marked with E. The whole is applied to the back of the panel P.

In Pig, 2 the luminous circuit diagram is shown broken down. The layers are drawn next to each other in the order

as they are applied to the glass panel P · The image layer G consists partly G ^ of letters, symbols, arrows lines and the like and partly G ₂ of layers of color · For the sake of simplicity, it is assumed that the sub-layers Gr ^ and ^ are in the same plane, as indicated by the corner marking. A third part is located on the same level. layer, which is not shown, and which gives the entire picture layer its basic color.

To assemble the device, first the symbols, Letters, files and lines as well as the frames Applied to the glass panel P for distinctive individual parts For this purpose, the parts of the image layer G> j wax letters, V / axis arrows, Vachs lines, etc., which gives them a certain Physical expansion obtained, which is visible in Pig · 3. is made cash. Here the detail A has been greatly enlarged ' and in theirs. Dimensions drawn out somewhat distorted Instead of using hatch letters, etc., you can go through part G ^ of the image layer by hand Application with a brush or by spraying on Apply stencils to the glass panel P. Be at the same time the borders for the recesses E are also marked

brought up by, the symbols for the powder device ;, the premixer and the water tank are colored. Different colors are used, for example blue for the water in the water tank, light blue for the Eaum above the water of the water tank, brownish for the premixer and light green for the conveyor system with feed point and discharge parts.

Then you can do it all with a layer of paint, for example with an ivory tone, overlapping sen as a background serves for the picture.

Finally, an aluminum color layer is used as the protective layer H sprayed on, which makes the whole picture invisible from the back. When applying the rope layer G ^ of the image and the protective layer E cover the recesses E within its border. The cover can easily be removed again after all this work has been completed so that the recesses become free · Han then pastes over them with pieces of thin, colored foil different color. For use as a protective layer H, self-adhesive films can be used if necessary peeled off again without affecting the underlying image layer.
