Arranged between the two end faces of these display bodies is a display body part that fills the entire space, the middle or full width of which is designed as a permanent magnet.

35 In diesem Falle aber muß die stabile Erhaltung der umgeschriebe- nen Information auch für den Fall gesichert werden, wenn das Ein¬ schreibmittel aus der Umgebung der Anzeigekörper entfernt wird.35 In this case, however, the stable preservation of the circumscribed Information can also be saved in the event that the writing means is removed from the surroundings of the display body.
Ziel der Erfindung ist die Beseitigung des Fehlens der Arre¬ tierung und die Schaffung derartiger Arretiermittel, die die 5 Stabilität der umgeschriebenen Informationen zufriedenstellend gewährleisten.The aim of the invention is to eliminate the lack of locking and to create locking means of this type which ensure the stability of the rewritten information satisfactorily.
Grundlage der Erfindung ist die erfinderische Überlegung, daß im Falle einer magnetischen Handsteuerung (z.B. mit einem Magnet¬ stift) die Arretierung der Anzeigekörper in den Endstellungen /ύ mittels in senkrechter Richtung zur Grundplatte gleitend ver¬ schiebbarer Weicheisenelemente, vorzugsweise mittels senkrecht zur Grundplatte gleitend verschiebbarer und verdrehbarer Dauer¬ magnetkörper erfolgen kann.The basis of the invention is the inventive consideration that, in the case of a magnetic manual control (for example with a magnetic pen), the display bodies are locked in the end positions / ύ by means of soft iron elements which can be slid in the vertical direction to the base plate, preferably by means of slidable elements perpendicular to the base plate and rotatable permanent magnetic body can take place.
Das Wesen der Erfindung besteht darin, daßThe essence of the invention is that
^5" - an der zur anzeigeseitigen Fläche der Grundplatte entgegenge¬ setzten Seite der Anzeigekörper mit zur Arretierung der Anzei¬ gekörper in den beiden Endstellungen geeignetem Dauermagnet versehene/s oder magnetisierbare/s Arretiermittel vorgesehen sind/ist, weiterhin o - die Magnetachsen der in den Anzeigekörpern befindlichen Dau¬ ermagnete einen Spitzwinkel mit der Grundplatte einschließen.^ 5 " - on the side opposite to the display-side surface of the base plate the display body with permanent magnet suitable for locking the display body in the two end positions or magnetizable / s locking means are provided, furthermore o - the magnetic axes of the in permanent magnets located on the display bodies include an acute angle with the base plate.
Die Erfindung wird mit Hilfe der in den Figuren dargestellten Beispiele ausführlicher beschrieben, wobei Fig.l eine mit Weicheisenplatten erfolgende Arretierung, 5 Fig.2 eine mit Weicheisenzylinder erfolgende Arretierung, Fig.3 eine mit Dauermagnetkugel erfolgende Arretierung darstellt.The invention is described in more detail with the aid of the examples shown in the figures, in which FIG. 1 represents a locking with soft iron plates, FIG. 2 shows a locking with soft iron cylinders, FIG. 3 shows a locking with permanent magnet ball.
Die in den Fig.1.-3. dargestellten Anzeigekörper 1 sind prismen- förmig und vorzugsweise um die in ihrer Schwerlinie angeordnete 3# Achse 2 verdrehbar ausgebildet. Die eine Kante des Anzeigekörpers 1 ist abgerundet und seine beiden Seiten, die in der der abgerun¬ deten Kante diagonal gegenüberliegenden Kante aufeinandertreffen, sind als zum Tragen voneinander abweichender Informationen geeig¬ nete Anzeigeflächen 3a,3b ausgebildet. Im Inneren der Anzeigekör¬ pers 1 ist ein Dauermagnet angeordnet, dessen Magnetachse 4 mit den beiden Anzeigeflächen 3a,3b einen Winkel, vorzugsweise einen 5 Winkel von 45 einschließt und zur Achse 2 des Anzeigekörpers 1 senkrecht verläuft. Die Achse 2 ist parallel zur Grundplatte 5 angeordnet.The in Fig.1.-3. Display body 1 shown are prism-shaped and preferably rotatable about the 3 # axis 2 arranged in their center of gravity. One edge of the display body 1 is rounded and its two sides, which meet in the edge diagonally opposite the rounded edge, are designed as display surfaces 3a, 3b suitable for carrying information which deviates from one another. A permanent magnet is arranged in the interior of the display body 1, the magnetic axis 4 of which forms an angle, preferably a 5 angle of 45, with the two display surfaces 3a, 3b and extends perpendicular to the axis 2 of the display body 1. The axis 2 is arranged parallel to the base plate 5.
Im Falle einer Handsteuerung, z.B. mittels eines Magnetstiftes erfolgenden Steuerung ist eine Arretierung der Anzeigekörper in /<? den beiden stabilen Randstellungen erforderlich. Nach den Bei¬ spielen wird die Arretierung in der Weise gelöst, daß der Magnet¬ kreis mit Hilfe eines Arretiermittels geschlossen wird.In the case of manual control, e.g. The control unit is locked in / <? the two stable marginal positions required. According to the examples, the locking is released in such a way that the magnetic circuit is closed with the aid of a locking means.
Der einfachste Fall ist in Fig 1 dargestellt. Hier ist das Arre¬ tiermittel eine in dem eine Verdrehung der Anzeigekörper 1 zulas- /5" senden Abstand angeordnete, zur Grundplatte 5 parallele Weichei¬ senplatte 6, wobei die mit der Weicheisenplatte 6 in Berührung bringbare Abrollfläche der Anzeigekörper 1 eine mit der Achse 2 der Anzeigekörper 1 übereinstimmende Achse aufweisende Zylinder¬ mantelfläche ist. Bei einer Verdrehung des Anzeigekörpers 1 um θ 90° aus der Lage nach Fig.l verdreht sich der Anzeigekörper 1 so entgegengesetzt dem Uhrzeigersinn, daß der Nord-Pol in die Nähe der Weicheisenplatte 6 gelangt. Diese Anordnung sichert aber nur in dem Falle die entsprechende Lösung, wenn die Weicheisenplatte 6 während der Verdrehung fortlaufend mit dem Anzeigekörper 1 in 5 Berührung bleibt, d.h. wenn die zwischen den Rändern der beiden Anzeigeflächen 3a,3b befindliche Abrollfläche des Anzeigekörpers 1 die Form eines viertel Zylidermantels aufweist.The simplest case is shown in Fig. 1. Here, the locking means is a soft iron plate 6, which is arranged at a distance of 5 "and which allows rotation of the display body 1, parallel to the base plate 5, the rolling surface of the display body 1 that can be brought into contact with the soft iron plate 6 being one with the axis 2 the indicator body 1 has a coincident axis with a cylindrical surface area. When the indicator body 1 is rotated by θ 90 ° from the position shown in FIG. 1, the indicator body 1 rotates counterclockwise so that the north pole comes close to the soft iron plate 6 However, this arrangement only ensures the corresponding solution if the soft iron plate 6 continuously remains in contact with the display body 1 during the rotation, ie if the rolling surface of the display body 1 located between the edges of the two display surfaces 3a, 3b is in the form of a quarter of a cylinder jacket.
Abhilfe zu diesem Problem bietet die Lösung nach Fig,2, wo hinter jedem Anzeigekörper 1 an der der anzeigeseitigen Fläche entgegen- θ gesetzten Seite der Grundplatte 5 eine Öffnung 7 vorgesehen ist. In der Öffnung 7 ist ein zur Bewegung in senkrechter Richtung zur Anzeigefläche der Grundplatte 5 gegeignetes, sich an die Wand 8 der Öffnung 7 locker anfügendes, aus Weicheisen gefertigtes Pris¬ ma oder ein Zylinder 9 angeordnet. Dieses Prisma oder dieser Zy- linder 9 steht - nach dem es/er zurückgedrückt werden kann - in ständiger Berührung mit dem Anzeigekörper 1 und liegt in den Randlagen des Anzeigekörpers 1 - von den Abrundungen abgesehen - mit seiner ganzen Oberfläche auf dem Anzeigekörper l.auf.The solution according to FIG. 2 offers a remedy to this problem, where an opening 7 is provided behind each display body 1 on the side of the base plate 5 opposite the surface on the display side. A prism made of soft iron or a cylinder 9 is arranged in the opening 7 and is suitable for movement in the direction perpendicular to the display surface of the base plate 5 and loosely attaches to the wall 8 of the opening 7. This prism or this cy Linder 9 is - after which it can be pressed back - in constant contact with the display body 1 and lies in the peripheral positions of the display body 1 - apart from the rounding - with its entire surface on the display body 1.
5 Soweit das in Fig.2. dargestellte Arretiermittel ein einen Dauer¬ magnet mit zur Ebene der Grundplatte 5 paralleler Magnetachse enthält, so ist vorzugssweise auch die Öffnung 7 zylinderförmig und die Arretierung erfolgt durch Verdrehen des Zylinders um 180° um seine eigene Achse. Unter einem Zylinder ist bezüglich vorlie- lö gender Beschreibung auch eine, eine wesentlich geringere Höhe als ihr Durchmesser aufweisende Scheibe zu verstehen, wobei es aber auch ein anderer, zum Verdrehen in der Öffnung 7 geeigneter Kör¬ per, insbesondere ein Drehkörper sein kann. In beiden Endstel¬ lungen verläuft die Magnetachse des im Zylinder befindlichen 5 Dauermagnets senkrecht zur Achse 2. Dieses Beispiel ist nicht ab¬ gebildet.5 As far as in Fig. 2. Locking means shown contains a permanent magnet with a magnetic axis parallel to the plane of the base plate 5, so the opening 7 is preferably also cylindrical and the locking takes place by rotating the cylinder through 180 ° about its own axis. In relation to the present description, a cylinder is also to be understood to mean a disk which has a considerably smaller height than its diameter, but it can also be another body which is suitable for turning in the opening 7, in particular a rotating body. In both end positions, the magnetic axis of the permanent magnet in the cylinder is perpendicular to axis 2. This example is not shown.
