Abstract

The front film (1) of thermoplastic or deep-drawn material has backing blocks (2) attached on the underside at the position where deformation is to take place to form the keys. The blocks (2) have recesses (6) to accept integrated snap disks (8) or LEDs. The sides of the block act as guide surfaces to ensure vertical movement of the keys. The block (2) is slightly smaller but deeper than the deformation of the film. The depth of the recess (6) corresponds to the compressed height of the disk (8). The block (2) is attached with adhesive (3) and made by injection molding or cut from sheet material.

Claims (7)

1. Design- und/oder Frontfolien aus thermoplastischem oder kalt-reckbarem Kunststoff mit Hilfe eines Negativformwerkzeuges, dadurch gekennzeichnet, dass die Folie an den Stellen, die tiefgezogen werden, Füllkörper aufweist, deren Konturen in etwa gleich und/oder gleich der Kontur der Tiefziehkavitäten sind, deren Profildicke jedoch wesentlich höher als die Profiltiefe der Tiefziehkavitäten sind und die entsprechend der Tiefziehkavitäten angeordnet und ausgerichtet sind, wobei die Füllkörper auf ihrer Unterseite eine Tastkappe integriert haben, die eine Vertiefung in Form der Schnappscheibe und/oder Ausfräsungen und/oder Lichtleitkammern für LEDs aufweisen, wobei die Kontur der Schnappscheibenvertiefung etwas größer als die äußere Form der Schnappscheibe ist und die Höhe der Vertiefung in etwa der Höhe der zusammengepressten kontaktierenden Schnappscheibe entspricht, so dass der Füllkörper bei Einsatz der Design- und/oder Frontfolie bei einer folienabgedeckten Tastatur auf Schnappscheibenbasis gleichzeitig als Anschlag gegen Beschädigung und unzulässiges Durchdrücken der Schnappscheibe dient.1. Design and / or front films made of thermoplastic or cold-stretchable plastic with the help of a negative molding tool, characterized in that the film has fillers at the points which are deep-drawn, the contours of which are approximately the same and / or the contour of the deep-drawing cavities are, the profile thickness of which is, however, significantly greater than the profile depth of the deep-drawing cavities and which are arranged and aligned in accordance with the deep-drawing cavities, with the filling bodies integrated on the underside of a tactile cap, which has a depression in the form of the snap disk and / or cutouts and / or light guide chambers for Have LEDs, the contour of the snap disc recess is slightly larger than the outer shape of the snap disc and the height of the recess corresponds approximately to the height of the compressed contacting snap disc, so that the filler body when using the design and / or front foil in a foil-covered keyboard r serves as a stop against damage and inadmissible pressing of the snap disk based on the snap disk. 2. Design- und/oder Frontfolien aus thermoplastischem oder kalt-reckbarem Kunststoff nach Anspruch 1, dadurch gekennzeichnet, dass die Tastkappen zur vertikalen Führung der Füllkörper dienen.2. Design and / or front foils made of thermoplastic or cold-stretchable plastic Claim 1, characterized in that the probe caps for vertical guidance of the Packing serve. 3. Design- und/oder Frontfolien aus thermoplastischem oder kalt-reckbarem Kunststoff nach einem der vorangehenden Ansprüche, dadurch gekennzeichnet, dass die Füllkörper fest mit der Folie verbunden sind.3. Design and / or front foils made of thermoplastic or cold-stretchable plastic one of the preceding claims, characterized in that the packing is fixed are connected to the film. 4. Design- und/oder Frontfolien aus thermoplastischem oder kalt-reckbarem Kunststoff nach einem der vorangehenden Ansprüche, dadurch gekennzeichnet, dass die Füllkörper als Spritzgussteile hergestellt sind.4. Design and / or front foils made of thermoplastic or cold-stretchable plastic one of the preceding claims, characterized in that the packing as Injection molded parts are made. 5. Design- und/oder Frontfolien aus thermoplastischem oder kalt-reckbarem Kunststoff nach einem der vorangehenden Ansprüche, dadurch gekennzeichnet, dass die Füllkörper aus Plattenmaterial hergestellt sind.5. Design and / or front foils made of thermoplastic or cold-stretchable plastic one of the preceding claims, characterized in that the filler body Plate material are made. 6. Design- und/oder Frontfolien aus thermoplastischem oder kalt-reckbarem Kunststoff nach einem der vorangehenden Ansprüche, dadurch gekennzeichnet, dass die Folie aus Polycarbonat oder Polyester ist.6. Design and / or front foils made of thermoplastic or cold-stretchable plastic one of the preceding claims, characterized in that the film Is polycarbonate or polyester. 7. Design- und/oder Frontfolien aus thermoplastischem oder kalt-reckbarem Kunststoff nach einem der vorangehenden Ansprüche, dadurch gekennzeichnet, dass die Folie eine Metallfolie ist.7. Design and / or front foils made of thermoplastic or cold-stretchable plastic one of the preceding claims, characterized in that the film Is metal foil.
