Description

Es sind Schutzmappen für Kinder-Schreibtafeln im Gebrauch, die meist aus Pappe gearbeitet sind, aber den Nachteil haben, daß sich ihre Breitseitenwände nach kurzem Gebrauch nach innen wölben und so zwangsläufig die Schrift auf der in der Büchermappe hin und her geschobenen Tafel verwischen. Die Erfindung behebt diesen Mangel dadurch, daß auf die Schreibflächen einer Schreibtafel Schutzplatten gelegt und durch Klemmfedern festgehalten werden, die über die Rahmenlängsleisten in entsprechende Nuten geschoben sind.There are protective folders for children's writing boards in use, mostly are made of cardboard, but have the disadvantage that their broad side walls after a short period of use, bulge inwards and so inevitably the writing on the in blur the blackboard pushed back and forth in the book case. The invention overcomes this Deficiency in that protective plates are placed on the writing surfaces of a writing board and are held in place by clamping springs, which over the frame rails in corresponding Grooves are pushed.

Bei dem in der Zeichnung dargestellten Ausführungsbeispiel zeigt Fig. i die Klemmfeder von oben und von der Seite gesehen, Fig. 2 die Draufsicht auf die Tafel und Fig. 3 den Querschnitt durch die Tafel mit Schutzplatten und Klemmfedern.In the exemplary embodiment shown in the drawing, FIG. 1 shows the clamping spring seen from above and from the side, FIG. 2 shows the top view of the panel and FIG. 3 shows the cross section through the panel with protective plates and clamping springs.

Die Klemmfedern i sind über den Tafelrahmen 3 geschoben und halten die Platten 5 fest. Ihre Schenkelenden, die die Leiste überragen, sind etwas nach innen gebogen, um ein unbeabsichtigtes Abstreifen vom Rahmen zu verhüten.The clamping springs i are pushed over the panel frame 3 and hold the plates 5 firmly. Your thigh ends, which protrude beyond the groin, are a little behind curved inside to prevent accidental stripping from the frame.

An allen vier Klemmfedern ist die Grifffläche 7 aufgerauht, um ein bequemes Zurückziehen der Klemmfedern beim Umlegen der Schutzplatten zu ermöglichen.On all four clamping springs, the gripping surface 7 is roughened to a to allow easy retraction of the clamping springs when turning over the protective plates.

Die Klemmfedern sind in den Nuten 6 so tief gebettet, daß sie mit dem Rahmen eine glatte Fläche bilden, so daß Beschädigungen an den Tischen und an den im Tornister befindlichen Büchern nicht vorkommen können. Der Erfindungsgegenstand gewährt einen sicheren Schutz gegen das Verwischen der Schrift auf der Tafel und bietet auch einen gewissen Schutz gegen mechanische Einwirkungen.The clamping springs are embedded in the grooves 6 so deep that they with Form a smooth surface on the frame, so that damage to the tables and on cannot appear in the books in the knapsack. The subject of the invention provides reliable protection against the smudging of writing on the board and also offers a certain protection against mechanical influences.

Die Schutzplatten können aus Materialersparnisgründen mit bekannten Mitteln versteift werden. Der Erfindungsgegenstand ist raumsparender und billiger als die Schutzmappe. Die Klemmfedern bleiben stets am Rahmen; die abzunehmende Schutzplatte der zu beschreibenden Tafelseite kann leicht und schnell an die andere Seite der Tafel gelegt werden, so daß ein Umbiegen der Schutzplatten vermieden wird.The protective plates can for reasons of material savings with known Means are stiffened. The subject of the invention is more space-saving and cheaper than the protective case. The clamping springs always remain on the frame; the protective plate to be removed the side of the board to be written on can be quickly and easily transferred to the other side of the Board are placed so that bending of the protective plates is avoided.
