Abstract

An electromagnetic indicator device which has a plurality of triangle-shaped trip-flaps (7), asymmetrical in relation to the rotation axis, which are arranged on a board (1) in the form of a matrix. A polarization magnet is applied to the trip-flap in the vicinity of the rotation axis. The movement of the rotatably supported trip-flaps from a first position into a second position is effected, as appropriate, by a permanently associated electromagnet (19) fixed behind the board (1). A network of support blocks (2) is fixed to the board (1), whereby each four support blocks (2) form the corner points of a square.

Description

Die Erfindung betrifft eine elektromagnetische Anzeigevorrichtung, bei welcher eine Vielzahl von, im Bezug auf die Drehachse asymmetrische Kippklappen auf einer Platte matrixförmig angeordnet sind, wobei an der Kippklappe ein Polarisationsmagnet in der Nähe der Drehachse angebracht ist und die Bewegung der drehbar gelagerten Kippklappe aus einer ersten Lage in eine zweite Lage durch einen fest zugeordneten, hinter der Platte angebrachten Elektromagneten erfolgt.The invention relates to an electromagnetic display device in which a plurality of tilting flaps which are asymmetrical with respect to the axis of rotation are arranged in a matrix on a plate, a polarization magnet being attached to the tilting flap in the vicinity of the axis of rotation and the movement of the rotatably mounted tilting flap from a first Layer in a second position by a firmly assigned electromagnet attached behind the plate.

Eine derartige Anzeigevorrichtung ist bereits bekannt. So wird in der EP-A-00 84 959 eine Anzeigevorrichtung beschrieben, bei welcher im Bezug auf die Drehachse asymmetrische Kippklappen zum Abdecken bzw. zur Freigabe einer Öffnung elektromagnetisch steuerbar sind. Die Kippklappen sind mit einem Permanentmagnet in der Nähe der Drehachse versehen.Such a display device is already known. EP-A-00 84 959 describes a display device in which asymmetrical tilting flaps with respect to the axis of rotation can be electromagnetically controlled to cover or to open an opening. The tilt flaps are provided with a permanent magnet near the axis of rotation.

Weiterhin ist eine Vorrichtung zur visuellen Darstellung von Zeichen bekannt, die aus mosaikartig nebeneinander in Reihen und Kolonnen angeordneten Anzeigeorganen besteht (DE-B-19 35 678), bei welcher die durch die Kippklappe bedeckbaren Flächen der Trägerplatte zu beiden Seiten der Drehachse entsprechend der jeweils sichtbaren Farbe der Kippklappe gefärbt sind. Bei dieser Vorrichtung ist die Kippklappe ebenfalls im Bezug auf die Drehrichtung asymmetrisch und zwar halbkreisförmig ausgebildet.Furthermore, a device for the visual representation of characters is known which consists of mosaic-like display elements arranged side by side in rows and columns (DE-B-19 35 678), in which the surfaces of the carrier plate which can be covered by the tilting flap on either side of the axis of rotation correspond to the respective visible color of the tilt flap are colored. In this device, the tilting flap is also asymmetrical with respect to the direction of rotation, namely semicircular.

Aufgrund ihres Aufbaus sind die bekannten Anzeigevorrichtungen sehr aufwendig und damit teuer in der Herstellung, außerdem lassen sich derartige Anzeigevorrichtungen nur in bestimmten Mindestgrößen herstellen, wobei die Anzeigefläche der Kippklappe in einer Größenordnung von mehr als einem Quadratzentimeter liegen muß.Because of their structure, the known display devices are very complex and therefore expensive to manufacture, and such display devices can only be produced in certain minimum sizes, the display area of the tilting flap having to be of the order of more than one square centimeter.

Die Aufgabe der Erfindung besteht darin, eine elektromagnetische Anzeigevorrichtung anzugeben, welche einen einfacheren Aufbau aufweist und damit eine wirtschaftlichere Herstellung ermöglicht, wobei auch sehr kleine Ausführungsformen herstellbar sind.The object of the invention is to provide an electromagnetic display device which has a simpler structure and thus enables more economical production, and very small embodiments can also be produced.

Diese Aufgabe wird dadurch gelöst, daß an der Oberseite der Platte ein Netz von Lagerböcken mit den Außenkanten derselben fluchtend angebracht ist, wobei jeweils vier Lagerböcke die Punkte eines Quadrats bilden, daß jeder Lagerbock das Lager für den Zapfen einer bzw. die beiden Lager für die Zapfen zweier benachbarter dreiecksförmiger Kippklappen aufweist, deren Drenachse mit der Hypothenuse zusammenfällt.This object is achieved in that on the top of the plate a network of bearing blocks is aligned with the outer edges thereof, with four bearing blocks forming the points of a square, that each bearing block is the bearing for the pin one or the two bearings for the Has pegs of two adjacent triangular tilt flaps, the drain axis of which coincides with the hypotenuse.

Durch die Anordnung der Lagerböcke, welche jeweils das Lager für den Zapfen einer bzw. die beiden Lager für die Zapfen zweier benachbarter Kippklappen aufweisen, in Verbindung mit der dreiecksförmigen Ausbildung der Kippklappen ist ein sehr kompakter Aufbau der Anzeigevorrichtung möglich. Bei der dreieckigen Form der Kippklappe ist die Gewichtsverteilung im Hinblick auf die Drehachse besonders günstig, dies hat eine größere Umschlaggeschwindigkeit und eine größere Stabilität in den Endlagen zur Folge.The arrangement of the bearing blocks, which each have the bearing for the pin of one or the two bearings for the pin of two adjacent tilting flaps, in conjunction with the triangular design of the tilting flaps, enables a very compact construction of the display device. With the triangular shape of the tilting flap, the weight distribution is particularly favorable with regard to the axis of rotation, which results in a higher turnover speed and greater stability in the end positions.

Aus der DE-A-25 13 550 ist bereits eine Vorrichtung zur Darstellung von Zeichen bekannt, bei welcher jeweils eine Reihe von Anzeigeelementen auf einem, die Zeile oder Spalte einer Anzeigematrix bildenden Plattenstreifen an den vier Eckpunkten eines Quadrats jeweils Stützen angeordnet sind, welche die Lagerstellen für die scheibenförmigen Wendeklappen bilden. Diese Wendeklappen sind symmetrisch und drehen sich um sich selbst von der einen Anzeigeposition in die andere Anzeigeposition.From DE-A-25 13 550 a device for displaying characters is already known, in which in each case a row of display elements is arranged on a plate strip forming the row or column of a display matrix at the four corner points of a square, which supports Form bearing points for the disc-shaped flaps. These flaps are symmetrical and rotate about themselves from one display position to the other display position.

Eine Weiterbildung der Erfindung besteht darin, daß die Spitze der Kippklappe abgerundet ist und die Lagerböcke eine beiderseitige Einschnürung aufweisen.A further development of the invention consists in that the tip of the tilting flap is rounded and the bearing blocks have a constriction on both sides.

Hierdurch wird erreicht, daß nahezu die gesamte Dreiecksfläche, d.h. die Hälfte des Quadats als Anzeigefläche genutzt werden kann. Weiterhin wird ein sehr kompakter Aufbau und damit ein gutes optisches Auflösungsvermögen erreicht. Weitere Vorteile ergeben sich aus den Unteransprüchen.This ensures that almost the entire triangular area, i.e. half of the square can be used as a display area. Furthermore, a very compact structure and thus a good optical resolution are achieved. Further advantages result from the subclaims.

Die Erfindung wird anhand eines Ausführungsbeispiels näher erläutert, welches in der Zeichnung dargestellt ist.The invention is explained in more detail using an exemplary embodiment which is illustrated in the drawing.

An der Oberseite der Platte 1 sind die Lagerböcke 2 angebracht und zwar derart, daß sie jeweils die Eckpunkte eines Quadrats bilden (Fig. 1). Die am Rand der Platte 1 liegenden Lagerböcke 2 bilden ein Lager für eine Kippklappe 7, während die übrigen Lagerböcke jeweils die beiden Lager zweier benachbarter Kippklappen aufweisen. Die Platte 1 weist 5 Spalten mit je 7 Kippklappen zur Darstellung von Buchstaben, Ziffern und Zeichen auf. Durch die Bohrungen 20 ragen, wie weiter unten noch näher erläutert wird, die Elektromagneten in die Platte 1. Die Bohrungen 20 werden durch eine aufgeklebte Folie 22 verdeckt, welche derart bedruckt ist, daß sich jeweils zwischen vier Lagerböcken 2 beispielsweise eine weiße une eine schwarze Fläche vorhanden ist. Die Kippklappen 7 sind auf der einen Seite ebenfalls weiß und auf der anderen Seite schwarz eingefärbt, so daß je nach Lage der Kippklappe eine weiße oder eine schwarze Fläche zwischen den die Eckpunkte eines Quadrates bildenden Lagerböcken vorhanden ist. Der Rand der Platte 1 ist an die außenliegenden Lagerböcke 2 soweit herangezogen, daß durch Aneinanderreihung weiterer Platten 1 an jeder Seite eine beliebig große Anzeigefläche gebildet werden kann, wobei der Abstand der nebeneinanderliegenden Kippklappen zweier Platten 1 ebenso groß ist, wie derjenige von zwei Kippklappen auf einer Platte 1.On the top of the plate 1, the bearing blocks 2 are attached in such a way that they each form the corner points of a square (Fig. 1). The bearing blocks 2 lying on the edge of the plate 1 form a bearing for a tilting flap 7, while the remaining bearing blocks each have the two bearings of two adjacent tilting flaps. Plate 1 has 5 columns, each with 7 tilting flaps to represent letters, numbers and characters. Through the holes 20, as will be explained in more detail below, the electromagnets protrude into the plate 1. The holes 20 are covered by a glued-on film 22, which is printed in such a way that between four bearing blocks 2, for example, a white and a black one Area is available. The tilt flaps 7 are also white on one side and colored black on the other side, so that, depending on the position of the tilt flap, there is a white or a black surface between the bearing blocks forming the corner points of a square. The edge of the plate 1 is used on the outer bearing blocks 2 so far that any size of display area can be formed by lining up further plates 1 on each side, the distance between the adjacent tilt flaps two Plate 1 is as large as that of two tilting flaps on a plate 1.

Die in Fig. 2 gezeigte Kippklappe 7 weist zwei in der Drehrichtung liegende Zapfen 6 auf, die in entsprechenden Lagern 5 zweier Lagerböcke 2 gelagert sind. Eine Kippklappe 7 dreht sich um 180° um die Drehachse 8 und ist auf der einen Seite weiß und auf der anderen Seite zwarz gefärbt. Selbstverständlich sind auch andere Farbkombinationen denkbar.The tilting flap 7 shown in FIG. 2 has two pins 6 lying in the direction of rotation, which are mounted in corresponding bearings 5 of two bearing blocks 2. A tilt flap 7 rotates 180 ° about the axis of rotation 8 and is white on one side and colored black on the other side. Of course, other color combinations are also conceivable.

Der in Fig. 3 gezeigte Schnitt zeigt die Kippklappen 7 in den beiden Lagen wobei der weiter unten noch näher erläuterte Polarisationsmagnet mit seinem Nordpol bzw. Südpol in der Nähe des weichen oder remanenten Kerns 21 des Elektromagneten 19 liegt. Die Betätigung der Kippklappen 7 erfolgt durch das magnetische Feld der Elektromagneten 19, dessen Richtung entweder durch eine Stromumkehr in dem Elektromagnet 19 oder durch eine weitere Wicklung erzeugt wird. Bei einem remanenten Kern 21 des Elektromagneten 19 ist eine erschütterungsfreie Lage der Kippklappen 7 sichergestellt.The section shown in FIG. 3 shows the tilting flaps 7 in the two positions, the polarization magnet, which will be explained in more detail below, with its north pole or south pole being close to the soft or remanent core 21 of the electromagnet 19. The tilting flaps 7 are actuated by the magnetic field of the electromagnet 19, the direction of which is generated either by a current reversal in the electromagnet 19 or by a further winding. With a remanent core 21 of the electromagnet 19, a vibration-free position of the tilt flaps 7 is ensured.

Die Elektromagenten 19 sind auf einer Leiterplatte 18 angebracht. Die Platte 1 ist an ihrer Unterseite mit Spreiznippel 24 und Nasen 23 versehen. Außerdem weist die Platte 1 an iher Unterseite Ausnehmungen 15 und Bohrungen 20 auf. Durch eine entsprechende Ausbildung des Spulenkörpers des Elektromagneten 19 zentriert sich dieser mit seinem Flansch 16 in die Ausnehmungen 15 und evtl. zusätzlich auch noch in die Bohrung 20. Die Leiterplatte 18 ist mit Bohrungen 28 versehen, in welche die Spreiznippel 24 einrasten und die Leiterplatte 18 gegen die Nase 23 Pressen. Auf der die Elektromagnete 19 tragenden Seite der Leiterplatte 18 sind Muttern 25 angebracht, welche die Befestigung der aus der Platte 1 und der Leiterplatte 18 bestehenden Anzeigevorrichtung an einem nicht gezeigten Rahmen ermöglichen, wobei an dem nicht gezeigten Rahmen eine Vielzahl von den erfindungsgemäßen Anzeigevorrichtungen angebracht werden kann.The electromagnets 19 are mounted on a circuit board 18. The plate 1 is provided on its underside with expanding nipples 24 and noses 23. In addition, the plate 1 has recesses 15 and bores 20 on its underside. By appropriate design of the coil body of the electromagnet 19, the latter is centered with its flange 16 in the recesses 15 and possibly also in the bore 20. The printed circuit board 18 is provided with bores 28 into which the expanding nipples 24 engage and the printed circuit board 18 23 against the nose. On the side of the printed circuit board 18 that carries the electromagnets 19, nuts 25 are attached, which enable the display device consisting of the plate 1 and the printed circuit board 18 to be fastened to a frame, not shown, wherein a plurality of the display devices according to the invention are attached to the frame, not shown can.

Wie bereits erwähnt, ragt der stiftförmige Kern 21 des Elektromagneten 19 bis in die Nähe der Oberfläche der Platte 1 in die Bohrung 20 hinein, wobei die Bohrung 20 durch die auf der Oberseite der Platte 1 angebrachte Folie 22 verschlossen wird.As already mentioned, the pin-shaped core 21 of the electromagnet 19 projects into the vicinity of the surface of the plate 1 into the bore 20, the bore 20 being closed by the film 22 attached to the top of the plate 1.

Der Aufbau eines Lagerbocks 2 wird in Fig. 5 gezeigt. Die Kippklappen 7 sind an der Spitze 12 ihrer Dreiecksfläche abgerundet und der Lagerbock 2 weist eine beiderseitige Einschnürung 4 auf, die derart ausgebildet ist, daß sie parallel zur Außenkante der Kippklappe 7 im Bereich der Spitze 12 verläuft. Durch diese Ausbildung der Kippklappe 7 und des Lagerbocks 2 ist eine besonders kompakte Ausführung, d.h. eine besonders enge Anordnung der Kippklappen möglich. Die nur ein Lager für den Zapen 6 der Kippklappe aufweisenden Lagerböcke 2 an dem äußeren Rand der Platte 1 (siehe Fig. 1) sind wie die eine Hälfte des zwei Lager aufweisenden Lagerbocks 2 ausgebildet, wobei jedoch die Einschnürung gradlinig bis auf die Drehachse fortgeführt ist (diese Form würde sich zwangsläufig ergeben, wenn die Kippklappe 7 eine der Dreiecksform entsprechende Spitze aufweisen würde).The structure of a bearing block 2 is shown in FIG. 5. The tilt flaps 7 are rounded at the tip 12 of their triangular surface and the bearing block 2 has a constriction 4 on both sides, which is designed such that it runs parallel to the outer edge of the tilt flap 7 in the area of the tip 12. This design of the tilting flap 7 and the bearing block 2 makes it particularly compact, i.e. a particularly close arrangement of the tilt flaps possible. The bearing blocks 2, which have only one bearing for the pin 6 of the tilting flap, on the outer edge of the plate 1 (see FIG. 1) are designed like one half of the bearing block 2, which has two bearings, but the constriction is continued in a straight line up to the axis of rotation (This shape would inevitably result if the tilting flap 7 had a tip corresponding to the triangular shape).

Die Lagerzapfen 6 werden in radialer Richtung durch die obere Lagerschale 3 und die untere Lagerschale 9 und in axialer Richtung durch die Lagerfläche 10 gelagert. Die Lagerzapfen 6 weisen ein abgerundetes Ende 11 auf, welches sich mit einem entsprechendem Lagerspiel gegen die Lagerfläche 10 legt.The bearing journals 6 are supported in the radial direction by the upper bearing shell 3 and the lower bearing shell 9 and in the axial direction by the bearing surface 10. The bearing pins 6 have a rounded end 11, which lies against the bearing surface 10 with a corresponding bearing play.

Aus fertigungstechnischen Gründen ist es vorteilhaft, die radiale Lagerung des Zapfen 6 auf zwei nebeneinander liegende Lagerschalen aufzuteilen. Die Ausbildung der Lagerschalen wird anhand entsprechender Schnitte in Fig. 4a und 4b erläutert. Die untere Lagerschale 9, welche derart angebracht ist, daß der Zapfen 6 nicht auf der Folie 22 aufliegt, wird durch ein Werkzeug gebildet, welches nach dem Spritzvorgang von der Oberfläche der Platte 1 senkrecht wegbewegt wird. Die obere Lagerschale 3 und der diese in Richtung der Drehachse unterbrechende Schlitz 26 wird durch zwei Werkzeuge gebildet, wobei nach dem Spritzvorgang beide Werkzeuge voneinander wegbewegt werden. Die Stoßstelle beider Werkzeuge liegt an einer beliebigen Stelle innerhalb des Schlitzes 26 jedoch nicht in der Nähe der Lagerschale 3. Die Breite des Schlitzes 26 ist etwas geringer als der Durchmesser des Zapfen 6, wodurch der Zapfen 6 durch den Schlitz 26 hindurchgedrückt werden kdW', um dann in der endgültigen Lage von der o en Lagerschale 3 und der unteren Lagerschale 9 gehalten zu werden.For manufacturing reasons, it is advantageous to divide the radial mounting of the pin 6 between two bearing shells located next to one another. The design of the bearing shells is explained on the basis of corresponding cuts in FIGS. 4a and 4b. The lower bearing shell 9, which is attached in such a way that the pin 6 does not rest on the film 22, is formed by a tool which is moved vertically away from the surface of the plate 1 after the spraying process. The upper bearing shell 3 and the slot 26 interrupting it in the direction of the axis of rotation is formed by two tools, with both tools being moved away from one another after the injection molding process. However, the joint of both tools is not at any point within the slot 26 in the vicinity of the bearing shell 3. The width of the slot 26 is be pushed slightly less than the diameter of the pin 6, whereby the pin 6 through the slot 26 Kdw ' to then be held in the final position by the upper bearing shell 3 and the lower bearing shell 9.

Die in Fig. 6 in vergrößerter Darstellung gezeigte Kippklappe 7 weist einen recheckigen Teil 13 auf, welcher sich von der Dicke des Zapfendurchmessers 6 auf die Stärke der Dreiecksfläche der Kippklappe 7 verjüngt. In dem rechteckigen Teil ist eine Ausnehmung 27 angebracht, welche knapp über die bis zur Drehachse 8 der Kippklappe 7 reicht Diese Ausnehmung 27 dient zur Aufnahme des Polarisationsmagneten 14. Dieser ist scheibenförmig ausgebildet und weist auf seiner Oberseite den einen Pol und an seiner Unterseite den anderen Pol auf. Der Polarisationsmagnet kann durch Verkleben an der Kippklappe 7 befestigt werden. Zweckmäßigerweise kann die den Polarisationsmagneten 14 tragende Seite der Kippklappe 7 schwarz oder entsprechend dunkel gefärbt sein, damit der Polarisationsmagnet 14 möglichst wenig sichtbar ist, während die andere Seite, die keine Ausnehmung 27 trägt, weiß oder entsprechend hell gefärbt ist.The tilting flap 7 shown in FIG. 6 on an enlarged scale has a rectangular part 13 which tapers from the thickness of the pin diameter 6 to the thickness of the triangular surface of the tilting flap 7. In the rectangular part there is a recess 27 which extends just above the axis of rotation 8 of the tilting flap 7. This recess 27 serves to receive the polarizing magnet 14. This is disc-shaped and has one pole on its top and the other on its underside Pole on. The polarization magnet can be attached to the tilting flap 7 by gluing. The side of the tilting flap 7 carrying the polarization magnet 14 can expediently be colored black or correspondingly dark, so that the polarization magnet 14 is as little visible as possible, while the other side, which has no recess 27, is colored white or correspondingly bright.

Wie bereits erwähnt, kann die Platte 1 vollständig durch einen Spritzvorgang aus einem thermoplastischen Kunststoff hergestellt werden. Ebenso können auch die Kippklappen 7 durch einen Spritzvorgang gefertigt werden.As already mentioned, the plate 1 can be produced entirely from a thermoplastic by an injection molding process. Likewise, the tilt flaps 7 can also be manufactured by an injection molding process.

Die obere Lagerschale 3 gemäß Fig. 4a muß nicht unbedingt halbrund sondern kann auch aus fertigungstechnischen Gründen eckig ausgebildet sein. Hierbei wird der Zapfen 6 der Kippklappe 7 durch die beiden Vorsprünge 30 von oben gehalten, welche durch den Schlitz 26 und die durch das Werkzeug für den Spritzvorgang bedingte Aussparung 29 in der Platte gebildet werden (Fig. 7a). Hierdurch läßt sich auch die Bildung eines Spritzgrates an der Lagerstelle vermeiden.The upper bearing shell 3 according to FIG. 4a does not necessarily have to be semicircular but can also be angular for manufacturing reasons. Here, the pin 6 of the tilting flap 7 held by the two projections 30 from above, which are formed by the slot 26 and the recess 29 caused by the tool for the injection molding process in the plate (FIG. 7a). This also prevents the formation of an injection burr at the bearing point.

Weiterhin kann auch auf die untere Lagerschale 9 verzichtet werden (Fig. 7b), so daß die Zapfen 6 der Kippklappe 7 nur von oben von der oberen Lagerschale 3 bzw. von den Nasen 30 gehalten wird, während die untere Lagerung der Zapfen 6 durch die Oberseite der Platte 1 bzw. die auf die Platte aufgeklebte Folie 22 außerhalb der Lagerböcke 2 gebildet wird. In diesem Fall muß die der Spitze der Kippklappe abgewandte Seite der Kippklappe 7 der Rundung der Zapfen 6 angepaßt sein.Furthermore, the lower bearing shell 9 can also be dispensed with (FIG. 7b), so that the pin 6 of the tilting flap 7 is only held from above by the upper bearing shell 3 or by the lugs 30, while the lower bearing of the pin 6 by the Top of the plate 1 or the film 22 glued to the plate is formed outside the bearing blocks 2. In this case, the side of the tilting flap 7 facing away from the tip of the tilting flap must be adapted to the rounding of the pins 6.
