Definitions
- the invention relates to a glass pane with image, letter and / or number code, in particular for the safety coding of motor vehicles, and a method for its production.
- a wide variety of anti-theft devices have been developed to prevent the theft of motor vehicles.
- a forgery-proof system is known, according to which identical, widely visible alphanumeric sequences of numbers (code numbers) are etched in a forgery-proof manner in each window of a motor vehicle.
- code numbers code numbers
- the code numbers etched into the glass panes being an integral part of the motor vehicle and not removable, because if the motor vehicle secured in this way is stolen, the perpetrators would also have to refurbish the chassis number, Replace engine number and license plate all discs, which significantly increases the cost of hairdressing.
- etching agents can also be easily removed by grinding. A deeper etching in of the code numbers, which could remedy this, is forbidden because this affects the strength of the glass panes. This applies in particular to motor vehicle front and rear windows that are under prestress.
- the code is either applied to a glued-on thin glass plate or contained there or the Code is covered by a glued-on glass plate.
- Adhesives that are used as adhesives are those that form a firm adhesive film and have a high stability against shear and tensile forces. Removal of the glued-on glass plate which contains or covers the coding is practically only possible by destroying the glass pane or causes such rough visible traces on the glass surface that the manipulation is clearly visible to the outside. Any techniques can be used to apply the code numbers, image motifs or sequences of letters, including those techniques which, after application, permit the code to be removed or corrected until the connection between the glass pane and the glass plate is finally established.
- the type of coding has the particular advantage that the glass pane is not weakened by the code. The edges of the glass plate are flattened, so that there is no impairment when the window pane of a motor vehicle is retracted or extended.
- the code is stamped onto the glass plate or the glass pane, preferably by means of light-fast stamping ink. Compared to the application by etching, there is therefore an easier producibility, which can also be used by non-specialists. Subsequent coding of vehicles by any letters or number sequences or even picture motifs is possible at any time.
- the glass plate has been roughened before stamping or other application of codes, which can preferably be done by etching.
- etching agents is not a problem here, since the etched surface is covered after gluing. Both surfaces adhering to one another are preferably roughened before the connection.
- the stamp color is lightfast, the adhesive UV-resistant.
- a thin glass plate is preferably used to prevent the glass pane from thickening.
- the glass plate should preferably have a maximum thickness of 1 mm.
- the glass plate is provided with bevelled edges and preferably merges continuously into the surface of the glass pane. This conical transition up to the rounding off of all edges not only eliminates the risk of injury when cleaning the glass pane, but also increases the security of the coding, since it is practically impossible to reach under the glass plate with a screwdriver or other pointed tools.
- the glass plate surface is rectangular, square, round or oval. If necessary, the glass plate can have a coating consisting of a holographic image, so that new possibilities are opened up for individual tamper-proof coding.
- the adhesive is preferably distributed over the entire surface of the glass plate in an application thickness which eliminates the haze caused by roughening before the adhesive bond by contact closure. Apart from the coding, the glass pane is thus also transparent in this area.
- the object stated at the outset is achieved in that a glass plate containing the coding is glued on or a glass plate is glued onto the glass pane via a coding.
- This process technology can be carried out or made up for at any time, even by non-specialists. The risk of damage to the glass pane or the impairment of the breaking strength can be effectively avoided.
- Special aids or special tools do not require the implementation of the method, which also has the advantage of being easy to handle.
- Special manual skills or special manual skills are not required.
- At least one of the contact surfaces is roughened, preferably both. B. can be done by etching.
- the coding is applied by stamping on one of the contact surfaces, for example on the glass plate. Any stamping or an erroneously incorrect code application can be corrected without further ado until the glass plate is fixed on the pane.
- the adhesive is applied point by point and, by pushing the glass plate back and forth on the glass pane, evenly over the contact Distributed areas, preferably until - apart from the stamped areas - the contact connection is transparent.
- the glass plate can be pushed back and forth by means of a frame into which the glass plate is inserted and surrounded by it.
- the wall surface of the frame facing the glass pane can, after the glass plate has been brought into the desired position, be provided with a contact adhesive in order also to hold the frame on the glass pane if the frame is to be retained on the latter, in particular then
- the frame consists of a plastic which is expediently colored with a signal color, such as yellow, orange, red, so that the frame serves simultaneously as an eye-catcher and as an indication of an existing coding, the frame also having color pigments which luminescent in the dark can be provided so that an afterglow occurs in the dark.
- 1 and 2 are perspective partial views of a glass pane and a glass plate
- FIG. 5 is a view along the section line VV, 6 and 7 the stamping of the glass plate according to FIGS. 4 and 5,
- FIG. 8 is a perspective view of a glass plate with a stamp
- FIG. 9 is a perspective view of a disc with a roughened partial surface
- 15 is a diagrammatic exploded view of the glass plate used in connection with a frame and provided with a code before being applied to the glass of a window pane,
- FIG. 16 is a perspective view of the rear side of the glass pane with the glass plate glued on and inserted into the frame,
- FIG. 17 is a front view of the frame in natural size
- Fig. 18 is an enlarged section along the line
- Fig. 19 is an enlarged section along the line
- FIG. 20 is a top view of a glass pane with a glass plate glued on, held in a frame and provided with a code, and
- Fig. 21 is a front view of a glass plate with a bar bar code.
- the glass pane 20 shown in FIG. 1 can be a motor vehicle glass pane, a window pane or a door glass pane.
- the glass pane has an inside 201 and an outside 202.
- coding is not etched into the outside or inside of the glass pane, but rather the glass pane is connected to a thin glass plate 30 according to FIG. 2.
- 2 shows the glass plate 30 in an enlarged representation.
- This glass plate 30 has bevelled edges 301 to 303 and, as can be seen from the sectional view according to FIG. 3, is trapezoidal in cross section. 4 and 5, the glass plate 30 is matted on its larger inside 304, for example by etching the surface 304.
- the code number is stamped or stamped with a lightfast color, for which colorfast colors are used.
- the stamp 40 leaves a stamp impression which, if necessary, can be corrected or supplemented before the gluing.
- FIG. 8 shows a thin glass plate 31 with stamped coding 312, e.g. B. "IDENT-FRAME".
- This coding is applied to the glass pane 20 as follows: First, a surface piece 203 is roughened, for example by applying an etchant. The size of the surface 203 corresponds to the size of the surface 304 of the glass plate 30 or 31.
- the sides with the respective matted surfaces or surface sections 311 and 203 face each other and UV-resistant adhesive is applied to the surface 311 at three points 32.
- the glass plate 31 is then pressed by light pressure against the vehicle window 20 onto the surface 203 after the adhesive has been distributed evenly over the roughened surfaces.
- the roughenings previously applied to the glass plate 31 and the pane 20 become transparent when using a crystal-clear adhesive.
- Epoxy resins, methacrylate resins or the like are expediently used as glass adhesives.
- the glass plates 30, 31 used are very thin and can practically only be removed by grinding or milling. However, the points on a glass pane treated in this way are immediately recognizable as manipulations.
- FIGS. 12 and 13 each show a glass pane 20 viewed from the inside 201 or the outside 202.
- the coding should expediently be attached so that it is legible from the outside and recognizable as coding.
- the glass plate 30, 31 provided with a code can also be applied directly to the glass pane 20 (FIG. 14).
- the glass plate 30, 31 is then permanently attached to the glass pane 20 by means of a suitable adhesive, such as contact adhesive.
- the glass plate 30, 31 according to another embodiment according to FIGS. 15 and 16 is arranged in a thin-walled frame 50 and together attached to the glass pane 20 by means of an adhesive.
- the frame 50 has a thickness corresponding to the thickness of the glass plate 30, 31, so that the surfaces of the frame 50 and the glass plate 30, 31 merge flush with one another (FIG. 20).
- the frame 50 has outwardly flattened edges 51, so that after the frame 50 has been glued to the glass plate 30, 31 on the rear side of the glass pane 20 or on the glass pane surface facing the motor vehicle interior, a stepless transition between the frame 50 and the glass pane surface is obtained, by means of which the handling of the glass pane 20 when opening and closing the window is not impaired and the glass pane can be easily guided past the rubber seals provided in the window area. Furthermore the frame 50 is used for aligning the glass plate 30, 31 provided with a code on the glass pane 20 if the glass plate has already been provided with the adhesive and placed on the glass pane 20.
- the frame 50 consists of a crystal-clear plastic or of a plastic which is preferably colored with a signal color or other color pigments.
- frame 50 made of a clear plastic provides the advantage that an inconspicuous attachment of the glass plate 30, 31 to the glass pane 20 is possible.
- Colored frames 50 have a signaling effect, to indicate from a distance that this is a motor vehicle that is secured by coding. Expediently z. B. in a four-door motor vehicle only one or two window panes with frames -50 around the coded and glued glass plates 30, 31 are provided.
- the frame 50 can also consist of a plastic colored with luminous pigments or coated with a luminous color.
- the luminescent pigments used here are inorganic or organic luminescent pigments which either show fluorescence or phosphorescence after being excited by electromagnetic radiation - so-called afterglow pigments - or are self-luminous luminescent materials. These luminescent pigments can also be used as daytime luminescent colors in the form of fluorescent (printing) colors in order to produce warning and signal effects.
- the glass plate 30, 31 can also be used for coding Bar (bar) code 312 ', preferably with an EAN code, provided and coated (Fig. 21).
- the glass plate 30, 31 should have a low thickness in order to prevent manipulation of the coding. If the coding on the back is changed with a color, the manipulation can be seen from the outside in the case of a thin glass plate, which is not the case with glass plates of greater thickness.
- the frame 50 can be provided with the coded glass plate 30, 31 together on the side of the frame 50 facing the glass pane 20 with an adhesive coating.
- the glass plate 30, 31 with the coding applied can, however, also be held in a clamped manner in the frame 50, which then consists of a resilient-elastic material, so that the glass plate 30, 31 is held in the frame 50 by means of a clamp fit.
- the frame 50 is secured on the glass pane 20 without adhesive, only held by the glued-on glass plate 30, 31.
