DE202005012021U1 - Antibacterial-3-D-coated front- and/or design foils, useful for e.g. foil keypad and display equipment, comprises decorative 3-D-protective coat (comprising polymer coating material with integrated silver ions) on the exterior of foils - Google Patents

Abstract

Antibacterial-3-D-coated front- and/or design foils (I), for the foil uncovered key pad, foil keypad, display equipment and/or front panel, comprises a decorative 3-D-protective coat (comprising solvent free, low viscosity, crystal clear, polymers coating material with integrated silver ions) on the exterior of the foils, where its three dimensional effect and high brilliance is obtained by UV-irradiation.

Description

The The invention relates to an antibacterial 3-D coated front and / or design foil for foil-covered Keyboards and / or membrane keyboards and / or displays and / or Front panels, whereby the 3-D coating by a solvent-free, low-viscosity, crystal-clear and / or colored polymeric coating material is achieved with integrated silver ions, which by UV irradiation a transparent and very flexible protective coating with three-dimensional Effect and high brilliance results.

So far known front and / or design foils for foil-covered keyboards and / or membrane keyboards and / or displays and / or are flat and / or slightly embossed executed. Therefore blind operation of the foil-covered keyboards and / or Membrane keyboards not possible and with front panels no raised logo or the like is possible. Further Membrane keyboards are known with domes of polyurethane composition, wherein the crests are glued to the foil, or be poured directly on it. However, these crests do not hold and come off; Using of appropriate solvents. Furthermore the known films are not antibacterial.

In the pamphlets US 5,681,575 WO 00/09 173 A1 describes the antibacterial action of silver ions as being generally known and in particular for coating medical devices used directly on the patient. For example, catheters are named. A disadvantage is the poor long-term behavior in terms of antimicrobial behavior. To improve z. B. in the US 5,681,575 Therefore, a chemical process listed, which is intended to improve the ion delivery in particular with body fluid contact.

Out The prior art is also known, a liquid Disinfectant on the surface of the foil-covered keyboard to spray on and rub with a cloth. Leave with this type of disinfection However, narrow cracks and gaps do not clean. Especially The cleaning of the edges around the filter glass panes is difficult and the controls.

It therefore remains despite intensive cleaning with a liquid disinfectant a not inconsiderable amount of contaminated dust and dirt on the keyboard. Furthermore is problematic that solvent-containing Disinfectants the skin and the organism of the operators strain. surfaces without antibacterial coating also provide a breeding ground for germs, bacteria and other microorganisms. Transmission thereof can be considerable Cause damage.

task The invention is an antibacterial 3-D coated front and / or design foil for foil-covered keyboards and / or membrane keyboards and / or displays and / or front panels to assist the user in the key operation foil-covered keyboards and / or membrane keyboards an extremely good tactile shift feel mediated and allows a blind operation, and those with three-dimensional High gloss effect is resistant to impact and elasticity, and is yellowing and UV resistant and glowing ads and the raised decorative logos and / or symbols may have and which is antibacterial.

These Problems are listed with the protection claim 1 listed antibacterial-3-D Front and / or design foil for foil-covered keyboards and / or membrane keyboards and / or displays and / or front panels solved by a front and / or design foils, which consist of PVC, polyester, metallic and polyurethane foils can, one or more tangible crowned 3-D protective coating in the form of crests and / or logos and / or symbols, wherein This 3-D protective coating of a low-viscosity, polymeric Coating material that is either crystal clear and transparent or is colored and has integrated silver ions.

The Antibacterial 3-D coated according to the invention Front and / or design foil for foil-covered Keyboards and / or membrane keyboards and / or displays and / or The front panel is therefore uneven and has one or more crests, i. to Outside directed projections, the outside at least Sectionally convex are. The crests are so high that they are clearly felt can. The crests can mark locations on foil-covered keyboards and membrane keypads, at which by depressing the 3-D-coated front and / or design foil, a key operation takes place. Therefore, the knobs on keyboards are preferably above the Buttons arranged, which allows a blind operation, as is the case with conventional foil-covered keyboards does not take place.

The 3-D protective coating can also be applied to other non-key-activated areas The film are, especially under the possible optical effect of 3-D protective coating as well as creating logos and symbols.

The inventive antibacterial 3-D-coated front and / or design film for Foil-covered keyboards and / or membrane keyboards and / or displays and / or front panels offers all the advantages of previous films used. It is characterized by good mechanical and chemical resistance, is antibacterial and can be used in practically all applications of conventional front and / or design films for foil-covered keyboards and / or membrane keyboards and / or displays and / or front panels.

A preferred embodiment the antibacterial 3-D-coated front and / or design foil for foil-covered Keyboards and / or membrane keyboards and / or displays and / or Front panel has transparent or translucent on the front 3-D protective coatings, preferably crystal-clear crests on. The crests have optical because of their convex convex curvature Lens effect. Therefore, the peaks are also suitable signal lights and control lights visually support and the readability of Keypad caption on the slide in a wide viewing angle to improve.

at Viewing windows e.g. above Displays open another area of application. So far, front and / or Design foil for foil-covered keyboards and / or membrane keyboards and / or displays and / or front panels usually structured foils are used, which are used in displays or the like. just one allow blurred viewing through the film. By the Application of a 3-D protective coating in the form of a flat dome in the window area can be a crystal clear transparency and a lower magnifying effect the readability of low-contrast display elements significantly improved.

Consequently the crests are in preferred embodiments also via signal lights or display elements arranged.

at a preferred embodiment the antibacterial 3-D-coated front and / or design foil for foil-covered Keyboards and / or membrane keyboards and / or displays and / or Front panels are the 3-D protective coatings in the form of crests elastic, what they are almost indestructible power. Pressure points, such as those caused by actuation by hard objects e.g. Schranbendreher, ballpoint pen or similar form, heal within residue-free for a few minutes out.

Preferably is the 3-D protective coating in the form of crests with the covering Design foil so firmly connected that they are not from this destructively let solve and consists of a solvent-free, low viscosity, crystal clear, polymeric coating material with integrated silver ions, transparent and through UV irradiation very flexible protective coatings with three-dimensional effect and high brilliance. Thereby, that in the summits silver ions are integrated, which are constantly released become, the surface becomes the crests sustainably protected against germs and bacteria. The surface the design foil of the keyboard has an antibacterial coating on, that on revolutionary The death of bacteria and germs in their contact with the film surface causes and hinders their reproduction.

Of the Floor plan of 3-D protective coating on the film can be designed almost freely can and can be both the key shape or the design design Take into account. So the floor plan can be e.g. circular, oval, rectangular or square with or without corner rounding or symbol outlines or logo outlines and areas represent. However, here too all possible floor plans are conceivable.

The Invention will be described below in embodiments with reference to Figures closer explained. It demonstrate:
