Definitions
- the present invention relates to a curved blackboard Sheet steel surface covered with a white coated preferably white enamelled surface is.
- a panel according to the invention comprises a rectangular panel surface which is surrounded by a protective frame.
- the curved panel is inserted into the grooves there, during assembly the upper and lower frames are first placed on the panel and then the side panels follow. So that the sheet does not rattle in the frame, the sheet metal plate is practically pre-stressed in the grooves, ie the sheet metal plate is held in the grooves by the restoring force.
- the panel could also be held by clamping pieces adapted to the radius of curvature of the panel.
- the back of the board can be coated with an anti-drumming agent or glued with another insulation material. It is also striking that drawers are provided in the side walls, in which accessories such as pens, cleaning cloths etc. can be accommodated. This means that all the necessary aids are always at hand.
- the invention it is also conceivable in front of the sheet steel plate to provide a plate made of transparent plastic.
- This solution has the advantage that in the space between the blackboard and the plastic plate diagrams, rulings or other images can be stored interchangeably. Both on the sheet steel plate, as well as on the possibly representations, Hold plans etc. with permanent magnets. Consists the transparent plate made of a material that is of the Ink is not attacked, can with appropriate Wetting behavior also on this plastic surface dry erase markers.

- Figure 2 shows in a sectional view that the table (1) in a Groove (11) is inserted in the upper frame (3). Also in the side cheeks (4, 5) a groove (12, 13) is provided in order to to give the board a good hold.
- the individual frame parts (2, 3, 4, 5) can be glued, screwed, welded together or otherwise connected. A detachable connection lends itself when the board (1) with a plastic plate should be covered and between plastic plate and blackboard (1) templates, rulings etc. can be inserted should.
- insulation material (10) can be provided on the back of the board (1).
- a coating with anti-drumming material or gluing with a foam layer is suitable. It is also conceivable to clamp a felt panel behind the board.

Description
Eine erfindungsgemäße Tafel umfaßt eine rechteckige Tafelfläche, welche von einem schützenden Rahmen umgeben ist. In diesen Rahmen ist die gebogene Tafel in dort vorhandene Nuten eingesetzt, wobei bei der Montage zunächst der obere und der untere Rahmen auf die Tafel aufgesetzt werden und anschließend die Seitenwangen folgen.
Damit die Tafel nicht im Rahmen klappert, wird die Blechplatte praktisch unter Vorspannung in die Nuten eingesetzt, d.h. durch die Rückstellkraft wird die Blechtafel in den Nuten klemmend gehalten.
Selbstverständlich sind auch andere Befestigungsarten denkbar. So könnte z.B. die Tafel auch durch dem Krümmungsradius der Tafel angepaßte Klemmstücke gehalten werden.
Damit beim Beschreiben der Tafel keine unangenehmen Geräusche auftreten, kann die Rückseite der Tafel mit einem Antidröhnmittel beschichtet oder mit einem anderen Dämm-Material beklebt sein. Ferner ist auffällig, daß in den Seitenwangen Schubladen vorgesehen sind, in denen Zubehör wie Schreibstifte, Reinigungstücher etc. untergebracht werden können. Somit sind alle benötigten Hilfsmittel stets griffbereit.
Es zeigen:

- eine perspektivische Vorderansicht der Tafel
- Fig.2 -
- einen Schnitt entsprechend der Linie II-II aus Fig. 1
- Fig. 3 -
- eine Seitenansicht der Wandtafel
- Fig. 4 -
- eine Draufsicht auf den oberen Rahmen der Tafel
In den Figuren nicht dargestellt ist die im Text beschriebene Ausgestaltung, daß die Tafel (1) aus Stahlblech durch eine Platte aus transparentem Kunststoff abgedeckt wird.
Auf der Rückseite der Wandtafel sind -hier ebenfalls nicht dargestellte- Aufhängeösen o.ä. vorgesehen.
