Description

  

  Leuchtschild, bei welchem Glaskörper in Bohrungen einer Metallplatte  angeordnet sind.    Es sind Leuchtschilder bekannt, bei wel  chen in den reihenweise in Schriftform an  geordneten Bohrungen von Metallplatten  Glaskörper angebracht sind. Da derartige  Schilder insbesondere dann, wenn sie elek  trische Beleuchtungseinrichtungen abdecken,  dicht sein müssen, hat man sich bemüht, die  Glaskörper dicht und dauerhaft in Bohrun  gen einzufügen.     Man    hat an den etwas kugel  förmigen Glaskörpern Zapfen ausgebildet,  welche die Metallplatte durchdringen und  hat auf deren Rückseite Befestigungsmittel  <U>aus</U> Metall oder Gummi angebracht.

   Die  Metallbefestigung verschafft keine dichte  Verbindung, so     .dass        Wasser    durch das Schild       dringen    kann. Die     Befestigungsteile    aus  Gummi schaffen höchstens für kurze Zeit  einen dichten Abschluss, sie werden dann  allmählich brüchig, so dass die Abdichtung  aufhört und die Glaskörper auch den Halt  verlieren. Ein völlig sicherer Sitz der Glas  körper wird mit Hilfe der Gummieinlagen    von vornherein niemals erzielt, da die Ver  bindung stets lösbar bleibt.  



  Diese Übelstände verhinderten bisher um  fangreiche Verwendung von Leuchtschildern  mit eingesetzten Glaskörpern, obwohl diese  Schilderart im übrigen grosse     Vorteile    bietet.  



  Nach der Erfindung können völlig dichte  Schilder mit dauerhaften und unlösbar be  festigten Glaskörpern dadurch erzielt wer  den, dass .die Glaskörper durch einen Email  überzug an der Platte befestigt sind. Es hat  sich ergeben, dass die Emaille beim Email  lieren der Schilder die Glaskörper vollkom  men sicher einbettet und     festhält    unter völlig  dichtem Abschluss aller Fugen     zwischen     Platte und Glaskörper.  



  In der Zeichnung ist eine beispielsweise       Ausführungsform    des     Erfindungsgegenstan-,     des dargestellt. Es zeigen:       Fig.    1 eine     Metallplatte    mit Bohrungen,       Fig.    2 die gleiche Platte nach Einsetzen  der Glaskörper,           Fig.3    eine Seitenansicht eines mit der       Leuchtplatte    versehenen Leuchtkastens,       Fig.    4 ,eine Anordnung mit     Scheinwerfer,          Fig.5    einen     Querschnitt    der     Platte    in  vergrössertem     Massstabe.     



  In der Metallplatte a sind in bekannter       Weise    die Bohrungen b reihenförmig, zum  Beispiel in Form eines Buchstabens<B>R,</B> an  geordnet. In diese Bohrungen sind die Glas  körper c eingesetzt, die durch den Email  überzug d unter - Abdichtung der Fugen  dauernd festgehalten werden. Die Leucht  platte kann in verschiedener Weise benutzt  werden,     beispielsweise    zur Abdeckung eines  Leuchtkastens e mit elektrischer Beleuch  tungsvorrichtung. Hier ist besonders die gute  Abdichtung von Bedeutung. Nach     Fig.    4    wird die Platte von der Rückseite mittelst  des Scheinwerfers f bestrahlt.



  Illuminated sign in which glass bodies are arranged in bores in a metal plate. There are luminous signs are known in wel chen in the rows in writing on ordered holes of metal plates glass bodies are attached. Since such signs must be tight, especially when they cover elec tric lighting devices, efforts have been made to insert the glass bodies tightly and permanently in Bohrun conditions. On the somewhat spherical glass bodies, pegs have been formed which penetrate the metal plate and fasteners made of metal or rubber have been attached to the rear of the latter.

   The metal fastening does not create a tight connection so that water can penetrate through the sign. The fastening parts made of rubber create a tight seal for a short time at most, they then gradually become brittle, so that the seal stops and the glass body also loses its hold. A completely secure fit of the glass body is never achieved from the outset with the help of the rubber inserts, as the connection can always be released.



  These inconveniences have hitherto prevented extensive use of illuminated signs with inserted glass bodies, although this type of sign also offers great advantages.



  According to the invention, completely airtight signs with permanent and permanently fixed glass bodies can be achieved in that the glass bodies are attached to the plate by an enamel coating. It has been shown that when the signs are enameled, the enamel embeds the glass body completely securely and holds it tightly, sealing all the joints between the plate and the glass body.



  In the drawing, an example embodiment of the subject matter of the invention is shown. 1 shows a metal plate with bores, FIG. 2 shows the same plate after the glass body has been inserted, FIG. 3 shows a side view of a light box provided with the light plate, FIG. 4 shows an arrangement with headlights, FIG. 5 shows a cross section of the plate on a larger scale.



  In the metal plate a, the bores b are arranged in rows in a known manner, for example in the form of a letter <B> R, </B>. In these holes, the glass body c are used, which are permanently held by the enamel coating d under - sealing the joints. The light plate can be used in various ways, for example to cover a light box e with electrical lighting device. Good sealing is particularly important here. According to FIG. 4, the plate is irradiated from the rear by means of the headlight f.
