Definitions

  • the invention relates to an electrical or electronic control keyboard.
  • the keyboard described in the aforementioned patent cannot be used in any location because of its volume.
  • the purpose of the present invention is to remedy this drawback, to produce an ultra-flat keyboard and to improve its performance.
  • the electrical or electronic control keyboard consists of a housing, a front closing plate which does not allow the magnetic flux to pass except at the locations of the lights provided for this purpose, a bulb (with blades and legs) by light, and placed in the housing and flush with the front face so as to detect the flow passing through the said light, a printed circuit in the bottom of the housing and to which the legs of the bulbs are connected, keyboard characterized in that only the 'one of the legs of each bulb is arranged under the corresponding lumen, while the body of the bulb with the other leg are placed under the solid part of the front plate.
  • the tab placed in front of the light is curved in a plane parallel to the front face. The flux generated by a magnet presented in front of the light can only reach one leg of the bulb. The flux is then led to the blades of the bulb which are attracted
  • a cable comes out laterally or through the back of the box to connect the bulbs to a decoder located at a distance.
  • the lights of the plate can be arranged in a continuous parallel line and at a short distance from the edge of the box.
  • the axis of each bulb passes substantially through the center of the plate and the center of a lumen.
  • Fig. 1 is a front perspective view without protective glass
  • Fig. 2 is a partial section along II-II of FIG. 1,
  • Fig. 3 is a top view, the indicator sheet being removed.
  • the keyboard consists of a box 1, of shallow depth closed by a front plate 2 comprising lights 3. From this box 1, a cable 4 comes out which connects it to another box 5, containing the coder-decoder device.
  • Fig. 2 shows the body of the bulb 9 arranged parallel under the solid part of the front plate 2. Only the tab 6 passes in front of the light 3. The tab 6 is bent and the free ends of the two tabs are fixed to a printed circuit * This circuit can be printed directly on. ' .the " bottom 19 of the box 1, or on a special plate 8 fixed to the said bottom of the box.
  • Fig. 3 shows that the bulbs 9 to 18 are arranged radially, each bulb is located in the axis going from the center of the box 1 to the center of a light 3.
  • the non-curved tabs 7 are all directed towards the center of the box.
  • the cable 4 preferably leaves the box 1 through the center of the bottom of the box.
  • the keyboard is strictly waterproof and can be submerged.
  • the lights 3 of the front plate 2 are filled with a resin (or another product) allowing the magnetic field to pass, and the front plate 2 is glued or welded in a sealed manner to the housing 1 Likewise, the outlet hole of the cable 4 is blocked by resin according to a preferred method of manufacture.
  • the keyboard as described is fixed or applied to the rear face of a window or any other non-magnetic plate, and each bulb is actuable by a magnet presented on the front face of said window, in line with the corresponding reference.
  • the command is transmitted to the codec-decoder 5 which can be distant from the keyboard.
  • the keyboard is thin, five millimeters for example, and of a small surface, square of five centimeters of side for example, so it is easily accommodated, see concealable inside a building or a piece of furniture .
  • the thickness of the glass (or of any other non-magnetic plate) is very different depending on the use case, and the magnetic flux which crosses it at a more or less long distance to be traversed by widening more or less .
  • the useful surface of each light is adaptable to this flow, and in fact adjustable according to
  • This adaptation can be carried out by various means. The technically simplest way is to remove the plate 2 and replace it with another plate externally of the same size, but whose diameter of the lights is different. One can also keep the existing plate 2 and subject to it another plate with lights at the same empla ⁇ cements but of smaller diameter.
  • the installer can have at his disposal a set of varied plates, the diameter of the lights of which differs according to the category of the plate, and choose at the time of assembly a plate of the category most appropriate for the distance provided between the bulb 9 and magnet 21, whether in the case of replacing the plate 2 or in the case of adding an additional plate.
