  Schultafel. 



   Gegenstand der Erfindung ist eine Schultafel mit mehreren vorteilhaft vier einzelnen Tafeln 2,   2-3,'4-5, 6-7, 8,   die mittels Zapfen 19 in seitlich angeordneten endlosen Ketten 13 des Gestelles 9 eingehängt sind. Diese Ketten laufen über obere und untere   Kettem'oIIen. ?   und 10 und werden durch die Handkurbel 16 angetrieben. Die Tafeln können mithin im Kreislauf im Gestell herum geführt werden. 



  Soll die Rückseite der Tafel beschrieben werden, so kippt man die Tafel aus der untersten Stellung um ihre Zapfen 19 hinauf   (Fig.   3 und 4), so dass sie auf die nächste Tafel zu liegen kommt, an welche sie durch einen Reiber 17 angedrückt wird, der am Seitenständer des Gestelles befestigt ist. Ein Riegel 15 mit Sperrad 14 dient dazu, die Kettenrolle und mithin die Ketten samt Tafeln in der jeweiligen Stellung gegen unbeabsichtigte Verschiebung zu sichern. Die Höhenverstellung der Tafeln kann auch durch blosses Erfassen der Tafeln (ohne Kurbel   16)   sehr leicht geschehen, da sich die vorne liegenden Tafeln mit den hinteren gegenseitig auswuchten. 



   Die   Anschläge   18 an den Seitenständern des Gestelles haben den Zweck, die jeweils oberste Tafel zu stützen. Bis zum Anschlagspunkt 18 kann die Tafel dann in jede passende Schreibhöhe gebracht werden. Zum Verhüten des Pendeln der Tafeln während des Zeichnen und Schreibens ist in der Mitte

  School board.



   The subject of the invention is a school board with several, advantageously four, individual boards 2, 2-3, '4-5, 6-7, 8, which are suspended by means of pins 19 in endless chains 13 of the frame 9 arranged on the side. These chains run over upper and lower chain pins. ? and 10 and are driven by the hand crank 16. The boards can therefore be circulated around the frame.



  If the back of the board is to be written on, the board is tilted up from its lowest position around its pin 19 (FIGS. 3 and 4) so that it comes to rest on the next board, against which it is pressed by a grater 17 attached to the side stand of the frame. A bolt 15 with ratchet wheel 14 is used to secure the chain roller and therefore the chains including panels in the respective position against unintentional displacement. The height adjustment of the panels can also be done very easily by simply grasping the panels (without crank 16), since the panels in front balance one another with the panels at the back.



   The stops 18 on the side stands of the frame have the purpose of supporting the topmost panel. The board can then be brought to any suitable writing height up to the stop point 18. To prevent the blackboard from swinging while drawing and writing is in the middle
