Definitions

  • Each disc guide channel has a first air channel followed by a supply section for [52] US. Cl 40/37, 40/ 106.21 40/l06.25, a plurality of non-transparent display discs displaceably 40/106 52 arranged in a row therein, a display section following [51] Int. Cl. 609i 11/06 such pp y section, said p y section being in the [58] Field of Search 40/37, 106.21, 106.52, f of a trace line for symbolizing a character at the 40/135, 106.25, 28 C; 35/37, 53 region of a display zone limited by a display window provided at a non-transparent cover plate of the plate [56] i References Cit d block.
  • Another object of this invention relates to a novel pneumatic display device wherein solely through pneumatic power it is possible to selectively portray different characters in a visual field in a most simple, accurate and reliable fashion.
  • the pneumatic display device of this invention is manifested by the features that there is provided a plate block incorporating a number of transparent plate members which are mounted above one another or in superimposed fashion.
  • Each such plate member incorporates a disc guide channel having a substantially rectangular crosssectional configuration which, starting from a first air channel forms a supply section for a multiplicity of non-transparent indicator or display discs displaceably arranged therein in a row with play, and following this supply section forming a display or indication section in the form of a trace or curved line for symbolizing a character at the region of a nontransparent cover plate of the plate block within a display window limited by a display zone or field, and at the end of this display section transforms into a second air channel in such a manner that upon blowing-in air into the first air channel of a preselected plate member the display discs are displaced out of the supply section thereof into the display section of the relevant disc guide channel, and therefore renders such visible in the form of a character at the display field and upon subsequent blowing-in air into the second air channel such display discs are again driven back into the supply channel of the relevant disc guide channel.
  • the display discs are advantageously constructed as circular discs with truncated conical side surfaces, for instance formed as plastic pressed or cast parts having a diameter of approximately 4.7 millimeters and a maximum thickness of approximately 0.85 millimeters when utilizing disc guide channels of 5 millimeters width and 1 millimeter depth.
  • FIG. 1 is a front view of a preferred embodiment of display device
  • FIG. 2 is a cross-sectional view of the display device depicted in FIG. 1, taken substantially along the line 11-" thereof;
  • FIG. 3 is an enlarged sectional view through a disc guide channel with a therein disposed display disc.
  • a multiplicity of substantially planar parellelly arranged plates are combined, for instance, by threadably connecting such with one another, into a plate block 20.
  • FIG. 2 such plate block 20 is illustrated and reference character G designates its base plate formed of any suitable non-transparent material upon which is placed a light passage-plate L formed of suitable glass clear transparent material, for instance acrylic resin, with smooth ground flank or side portions 21.
  • a number of, for instance 10, display or indicator plates A0, A9, A8 A2, A1 are likewise formed of a transparent material.
  • each indicator plate A0, A9, A8, and so forth each contain at their associated base surface a respective channel K constructed in the form of an appropriate continuous trace or line.
  • the channels K of any given indicator plate with the exception of the last one, such as plate A0, are closed by the rearface of the plate mounted thereover.
  • a cover plate D On top of the uppermost indicator or display plate A0 there is mounted a cover plate D, likewise formed of transparent material.
  • a front plate F formed of non-transparent material. This front plate F is equipped with a window cut-out or recess Fl which leaves free therein a display zone or field 22.
  • FIG. 1 there is illustrated the channel K of the uppermost display plate A0.
  • This plate is constructed to display the character 0 by means of its channel K.
  • Each of these channels K of the display plates defines a disc guide channel and consists of four sections, namely a first air channel section Kl, a supply channel section K2 of the disc guide channel, an indicator section K3 of the disc guide channel as well as a second air channel section K4. Only the indicator section K3 of the disc guide channel of each display or indicator plate Al, A2, A3 and so forth is disposed at the region of the indicator or display zone 22 defined by the window section F1 of the front plate F.
  • These indicator or display sections K3 are each constructed as traces or curved lines for symbolizing a respective character, for instance as depicted in FIG.
  • the supply section K2 between the indicator section K3 and the first air channel Kl merges without any narrowing or tapering-down of its crosssection into the indicator or display section K3.
  • the respective transition regions 25 and 26 from the first air channel Kl to the supply section K2 and from the indicator or display section K3 to the second air channel K4 are tapered or narrowed, as shown in FIG. 1.
  • the actual disc guide channel proper incorporating the channel sections K2 and K3, contains therein for sliding movement with play a multiplicity of circular indicator or display discs AS formed of a nontransparent material, for instance colored plastic.
  • each indicator or display disc AS are formed as truncated cones.
  • the number of display discs AS which are to be used must be large enough that they are sufiicient to completely fill the display section K3 of the relevant disc guide channel at the display zone, and the length of the supply section K2 of each disc guide channel must be sufficient for accommodating all of the display discs AS.
  • the air channels Kl for each disc guide channel K are guided or lead up to a respective transverse bore, similarly the air channels K4.
  • These transverse bores are arranged in a grid field indicated by the character in such a way that they, without intersecting another channel, permit connecting the channels of each display plate A1, A2, A3, etc. at both ends to an air infeed.
  • the transverse bores of the plate A0 for the air channels K1 and K4 are connected with both outputs 23 and 24 of a fluidic element E which under the influence of a pneumatic control signal El conducts air via output 23 to the air channel K1.
  • This air current is sufficient in order to drive all of the display discs AS out of the supply section K2 into the indicator section K3 of the relevant disc guide channel, so that the numeral 0 is visible.
  • the signal El at the fluidic element E is no longer efiective, then air flows to the other output 24, that is to say, to the air channel K4. Consequently, the display discs AS are driven out of the display section K3 and back into the supply section K2, and thereafter a different character can be rendered visible.
