Definitions

  • the invention relates to a keyboard according to the preamble of claim 1, a method for their preparation according to the preamble of claim 5 and a use.
  • a keyboard according to the preamble of claim 1 is known from DE 10 2004 021 542 A1 known.
  • This keyboard has a cover layer with openings in which a cap is slidably guided.
  • the cap acts on a keypad having elastic domes which are linearly reciprocable and contain electrically conductive material which, upon depression of the dome, contacts an underlying switching grid thereby closing an electrical contact.
  • the elastic properties of the dome provide a restoring force, so that after releasing the cap, this returns to a starting position and the electrical contact is opened.
  • a variant of the keyboard also shown there uses instead of the movably guided caps a continuous flexible cover layer with printed key symbols, which are arranged over the tops of the keypad.
  • a similar keyboard is from the DE 37 41 750 A1 known.
  • This keyboard has a film whose surface sealing tightly, are arranged under the predetermined areas of electrical contacts which can be actuated by applying pressure to these areas of the film, to achieve a larger actuation stroke above the predetermined areas of the film away arched caps made of elastic Material are arranged, which have in the interior directed to the film centric plunger whose longitudinal axis is perpendicular to the plane of the film. Upon deformation of the domed portion of the respective cap, the plunger is pressed onto the foil and deforms it via a path sufficient to actuate the electrical contact.
  • the caps and the cover layer are made of hard plastic, the cover layer having a U-shaped profile around the openings for the caps in order to guide the caps correctly during their movement. It follows that the cover layer and the caps must each be made individually by injection molding, which is expensive. Next, the caps must be used individually in the openings during assembly, which makes the assembly consuming.
  • Object of the present invention is to improve the aforementioned keyboard and the method for their production to the effect that manufacturing and assembly costs are substantially reduced.
  • the basic idea of the invention is, in the case of a keyboard with a switching foil which has elastically movable raised switching domes, a cover plate and covers of the switching domes, to cut off the covers of the switching domes from the cover plate and fasten them to the upper side of the switching domes.
  • the cut out of the cover plate parts are thus used as key covers.
  • the cover plate is attached in one operation at the top of all switching domes, which is preferably done by gluing, and then the covers cut out, which is preferably done by means of laser beam cutting.
  • the cover plate and the covers of the switching domes are preferably made of transparent material, wherein labels are applied in particular to the covers of the switching domes on the inner side of the covers of the switching domes facing the switching domes. This can be done in a conventional manner by printing methods such as screen printing, pad printing, etc., or in the following manner:
  • the entire inside of the cover plate is coated with a top color, which is black, for example.
  • a top color which is black, for example.
  • the corresponding inscription is preferably prepared by removing the cover color by means of a laser beam, and then a color is applied to the inscription in a third step.
  • the cover plate need not be a flat "plate” in the strict sense. It can also be a curved plate, a shaped semi-finished product or a molded part, such. an upper housing part, be.
  • the keyboard of Fig. 1 has a cup-shaped housing lower part 1, which is for example injection molded from plastic.
  • a contact plate 2 is used, which has a plurality of switching contacts 3 and associated, not shown interconnects and also not shown electronic circuits.
  • Switching film 4 is set, which has a plurality of flexible switching domes 5, which have contactors in a known manner, which contacts an associated pair of switching contacts 3 upon depression of the switching dome 5 and thus establishes an electrical connection.
  • the switching dome 5 are made of flexible elastic material, so that the respective switching dome automatically returns after depressing and releasing back to its initial position in which its contactor is released from the associated switching contacts 3.
  • switch film and contactors can be used, such as metal leaf springs, embossed films, silicone mats with carbon pressure or other known in the art types of contacting.
  • the switching domes 5 preferably have a flat surface 6.
  • an intermediate plate 7 is set, which has openings 8 associated with the switching domes.
  • a cover plate 9 is arranged, from which, as will be described, the individual switching domes associated key covers 10 which are connected to the surface 6 of the associated switching dome 5, are cut out.
  • the lower housing part 1 has in its interior a plurality of inwardly projecting webs 11 which cooperate with corresponding recesses 12 and 13 of the contact plate 2 and the switching foil 4 to position the contact plate 2 and the switching film 4 and to hold against displacement.
  • the lower housing part 1 has a battery compartment 14 for a power supply, wherein the electrical connections and compounds are not shown for the sake of clarity.
  • Fig. 2 differs from that of Fig. 1 only in that the intermediate plate 7 is omitted.
  • the essential function of the intermediate plate 7 is to hold the cover plate 9. But it is also possible to connect the cover plate 9 directly to the lower housing part 1.
  • the planar cover plate 9 shown here made of transparent material, e.g. Plexiglas or other plastic is coated on its underside, which faces the inside of the housing 1 with fully assembled keyboard, with a top coat, which is for example sprayed or applied in any other known manner.
  • a corresponding inscription is prepared by removing the abovementioned cover color in the respective form of the desired inscription, which is preferably effected by means of a laser beam.
  • a clearly visible color is applied, which covers the "lasered away" inscription and the adjacent areas still provided with the black color.
  • different colors can be selected for the individual keys.
  • the lettering may also be printed in other ways, e.g. be applied by printing.
  • the prepared with caption cover plate is then optionally connected to the interposing plate 7 with the switching film 4 by the surfaces 6 of the switching dome 5 in the correct alignment with the future key covers 10 are preferably glued.
  • Other types of fastening such as ultrasonic welding, thermal welding, are also possible.
  • the button covers 10 are then cut out on the future buttons, which is preferably done by means of a laser beam.
  • Other cutting methods such as e.g. Water jet cutting, but are also conceivable.
  • the key covers 10 are then firmly connected to the switching domes 5 of the switching film 4 due to the previous fastening or gluing.
  • laser beam cutting is of course to ensure that the depth of cut is chosen so that only the cover plate 9 is cut through, but the switching film 4 is not injured.
  • the subsequent assembly is then very simple.
  • the contact plate 2, the switching foil 4 together with the glued-key covers 10 and possibly the intermediate plate 7 are inserted into the housing, wherein the webs 11 and the recesses 12 and 13 provide correct guidance and positioning.
  • the intermediate plate 7 is then attached to the lower housing part, for example by gluing, welding or other known methods.
  • the key covers 10 then pass through said openings of the cover plate 9 and, depending on the thickness of the intermediate plate or positioning of the individual elements in the housing lower part 1, lie exactly in the surface of the cover plate 9 with its surface. But you can also optionally protrude upwards from the surface or arranged offset down.
  • the intermediate plate 7 may have a plurality of spacers 15 which may be mounted on the switching foil 4 or parts of the housing 1, e.g. support the webs 11.
