Description

Die Erfindung betrifft eine modulare Anzeigevorrichtung für optische Signale gemäß dem Oberbegriff des Anspruchs 1 sowie ein Werkzeug zum Entfernen von Anzeigemodulen aus dem Tragrahmen einer modularen Anzeigevorrichtung.The invention relates to a modular display device for optical signals according to the preamble of claim 1 and to a tool for removing display modules from the support frame of a modular display device.

Modulare Anzeigevorrichtungen sind z.B. aus EP-A-0559124, WO 00/65432 A und FR-A-2749693 bekannt.Modular display devices are e.g. from EP-A-0559124, WO 00/65432 A and FR-A-2749693.

Eine Anzeigevorrichtung dieser Art ist in der DE 199 51 348 A1 beschrieben. Diese Anzeigevorrichtung weist ein aus mehreren gleichen Anzeigemodulen gebildetes Anzeigefeld auf, wobei die Anzeigepunkte jeweils zeilen- und spaltenweise angeordnet sind und durch eine Steuereinrichtung gesteuert werden. Die Befestigung der einzelnen Modulgehäuse in der Tragekonstruktion erfolgt über Verschraubung eines winkeligen Haltemittels, das an der Vorderseite des Modulgehäuses angreift, an der Tragekonstruktion. Nachteilig an einer solchen Befestigung ist insbesondere, dass die einzelnen Modulgehäuse zum einen nicht unmittelbar aneinander angrenzend angeordnet werden können und somit kein einheitliches Anzeigefeld geschaffen wird, das auch für alle Arten modulübergreifender Signalanzeigen geeignet ist. Zum zweiten ist die Befestigung mittels Verschraubung relativ zeitaufwendig und kompliziert, denn es ist insbesondere beim Herausnehmen von Modulen notwendig, neben dem Lösen der Schrauben auch die Modulgehäuse festzuhalten, damit diese nicht aus der Tragekonstruktion fallen, was zudem bei in beträchtlicher Höhe, z.B. quer über eine Autobahn, verlaufenden Anzeigevorrichtungen eine Gefahr für den Arbeiter darstellt.A display device of this type is described in DE 199 51 348 A1. This display device has a display field formed from a plurality of identical display modules, wherein the display points are each arranged in rows and columns and are controlled by a control device. The attachment of the individual module housing in the support structure via screwing an angled holding means which engages the front of the module housing, on the support structure. A disadvantage of such a fastening is in particular that the individual module housing for a not directly adjacent to each other can be arranged adjacent and thus no uniform display panel is created, which is also suitable for all types of cross-module signal displays. Secondly, the fastening by means of screwing is relatively time-consuming and complicated, because it is necessary in particular when removing modules, in addition to loosening the screws also hold the module housing so that they do not fall out of the support structure, which also at considerable height, for. across a highway, running display devices pose a danger to the worker.

Es ist daher die Aufgabe der vorliegenden Erfindung, eine modulare Anzeigevorrichtung für optische Signale zu schaffen, die in der Lage ist, auch über die Grenzen der einzelnen Module hinweg alle möglichen Arten von großflächigen Signalanzeigemotiven darzustellen und gleichzeitig einen besonders einfachen und sicheren Austausch einzelner Module zu ermöglichen.It is therefore the object of the present invention to provide a modular display device for optical signals, which is able to represent across the boundaries of the individual modules away all sorts of large-scale signal display motifs and at the same time a particularly simple and secure exchange of individual modules enable.

Of course, a variation of the number and the distribution of the signal fields 6 in the individual display modules 4 is possible. The display device 1 is usually attached via the support frame 3 to a supporting device, not shown, such as a post, a Schilderbrückentragekonstruktion or other suitable and known support devices.

In Fig. 2 ist eine bevorzugte Ausführungsform eines Anzeigemoduls 4 dargestellt. Das Anzeigemodul 4 besteht aus einem Modulgehäuse 8, das eine Frontplatte 10 mit integrierten Signalfeldern 6 sowie einen rückwärtigen Grundkörper 12 mit vier Seitenwänden 14 und einer Rückwand 15 umfasst. Die Frontplatte 10 und der Grundkörper 12 sind vorzugsweise durch Kleben miteinander verbunden, und im Inneren des Grundkörpers 12 befinden sich die hier nicht dargestellten elektrischen/elektronischen Einheiten einschließlich der lichtgebenden Einheiten, die durch eine zentrale Steuereinrichtung (ebenfalls nicht gezeigt) in an sich bekannter Weise angesteuert werden. An mindestens zwei gegenüberliegenden Seitenwänden 14 sind Halteelemente 16 angeordnet, die hier im dargestellten Ausführungsbeispiel als von der jeweiligen Seitenwand 14 des Modulgehäuses 8 abstehende Haltenasen ausgebildet sind. Diese Haltenasen 16 sind etwa auf einem Drittel der Tiefe des Modulgehäuses 8 an den Seitenwänden 14 angeordnet, wobei vorzugsweise auf einer Seitenwand zwei voneinander beabstandete Halteelemente 16 angebracht sind, während auf der gegenüberliegenden Seitenwand lediglich ein zentrales Halteelement 16 vorhanden ist.2, a preferred embodiment of a display module 4 is shown. The display module 4 consists of a module housing 8, which includes a front panel 10 with integrated signal fields 6 and a rear body 12 with four side walls 14 and a rear wall 15. The front panel 10 and the base body 12 are preferably connected to each other by gluing, and inside the base 12 are not shown here electrical / electronic units including the light emitting units by a central control device (also not shown) in a conventional manner be controlled. On at least two opposite side walls 14 holding elements 16 are arranged, which are formed here in the illustrated embodiment as of the respective side wall 14 of the module housing 8 projecting retaining lugs. These retaining lugs 16 are arranged approximately at one-third of the depth of the module housing 8 on the side walls 14, wherein preferably two spaced-apart holding elements 16 are mounted on one side wall, while on the opposite side wall, only a central holding element 16 is present.

Der Grundkörper 12 ist an den Seitenwänden 14 in seinem hinteren Bereich vorzugsweise nach innen abgeschrägt, wodurch das Einfügen des Modulgehäuses 8 in das dafür vorgesehene Einschubfach im Tragrahmen 3 erleichtert wird. Außerdem sind als weitere Führungs- und Halterungshilfen an der Rückwand 15 des Modulgehäuses 8 bevorzugt vier Einführstifte 18 angeordnet, die, wie später beschrieben wird, in entsprechende Ausnehmungen des Tragrahmens 3 eingreifen. Die Frontplatte 10 ragt an den Seiten vorzugsweise leicht nach außen über den Grundkörper 12 hinaus, so dass die Frontplatten 10 von nebeneinanderliegenden Modulgehäusen 8 im eingebauten Zustand nahezu unmittelbar aneinander angrenzen.The base body 12 is preferably beveled inwardly on the side walls 14 in its rear region, thereby facilitating the insertion of the module housing 8 into the insertion compartment provided in the support frame 3. In addition, four insertion pins 18 are preferably arranged as further guide and support aids on the rear wall 15 of the module housing 8, which, as will be described later, engage in corresponding recesses of the support frame 3. The front panel 10 preferably projects slightly outwardly beyond the base body 12 on the sides, so that the front panels 10 of adjoining module housings 8 in the installed state almost directly adjoin one another.

In Fig. 3 ist eine entsprechende Frontplatte 10 abgebildet. Die Frontplatte 10 weist mehrere Signalfelder 6 auf, die in Zeilen und Spalten angeordnet sind. Die Signalfelder 6 sind jeweils als einstückige Abdeckeinheiten ausgebildet und in die dafür vorgesehenen Öffnungen der Frontplatte 10 eingesetzt. Ein Signalfeld 6 besteht üblicherweise aus mehreren, hier vier Linsenelementen 20, die in die Abdeckeinheit integriert sind und zur Bündelung des Lichts dienen, das eine hinter der Frontplatte 10 im Inneren des Grundkörpers 12 angeordnete Lichtquelle, vorzugsweise eine Leuchtdiode, abstrahlt. Durch die hier beschriebene Anordnung wird das Licht von jeweils vier LEDs zu einem Signalpunkt gebündelt, was zu einer besonders hohen Leuchtstärke führt.In Fig. 3, a corresponding front panel 10 is shown. The front panel 10 has a plurality of signal fields 6 arranged in rows and columns. The signal fields 6 are each formed as one-piece cover units and in the openings provided for Front panel 10 used. A signal field 6 usually consists of several, here four lens elements 20, which are integrated into the cover unit and serve to bundle the light, which emits a behind the front panel 10 in the interior of the main body 12 arranged light source, preferably a light emitting diode. By the arrangement described here, the light is bundled by four LEDs to a signal point, which leads to a particularly high luminous intensity.

An den Seitenrändern der Frontplatte 10 sind längliche Ausnehmungen 22 vorhanden, die sich auf Höhe der Halteelemente 16 befinden. Diese Ausnehmungen 22 gehen üblicherweise direkt vom Rand der Frontplatte 10 aus.On the side edges of the front panel 10 elongated recesses 22 are present, which are located at the level of the holding elements 16. These recesses 22 usually go directly from the edge of the front panel 10.

In Fig. 4 ist ein Querschnitt durch zwei in den Tragrahmen 3 eingesetzte und dort befestigte Modulgehäuse 8 dargestellt. Es ist zu erkennen, dass die beiden Frontplatten 10 unmittelbar aneinander angrenzen und der Tragrahmen 3 zwischen zwei Einschubfächern einen V-förmigen Abschnitt 23 aufweist, der der abgeschrägten Form der Seitenwände 14 der Modulgehäuse 8 angepasst ist.FIG. 4 shows a cross section through two module housings 8 inserted into the support frame 3 and fastened there. It can be seen that the two front panels 10 adjoin each other directly and the support frame 3 between two slots has a V-shaped portion 23 which is adapted to the tapered shape of the side walls 14 of the module housing 8.

In Fig. 5 ist ein detaillierter Ausschnitt einer Anzeigevorrichtung 1 mit mehreren eingesetzten Modulgehäusen 8 dargestellt, von denen jeweils die Frontplatte 10 mit den angedeuteten Signalfeldern 6 sichtbar ist. Im Mittelbereich der Abbildung ist zur Veranschaulichung des Befestigungsmechanismus der Modulgehäuse 8 am Tragrahmen 3 ein leeres Einschubfach für ein Modulgehäuse 8 gezeigt. Auch hier sind die senkrecht angeordneten V-förmigen Abschnitte 23 des Tragrahmens 3 sichtbar, die in Kontakt mit den abgeschrägten Seitenwandbereichen des Modulgehäuses 8 kommen, wenn das Modulgehäuse 8 in das Einschubfach eingeschoben wird. Ebenfalls erkennbar sind die vier Durchtrittslöcher 24 zur Aufnahme der Einführstifte 18 des Modulgehäuses 8, die in parallel zur Anzeigefläche orientierten Schienen 26 des Tragrahmens 3 angeordnet sind.FIG. 5 shows a detailed section of a display device 1 with a plurality of inserted module housings 8, of which in each case the front plate 10 with the indicated signal fields 6 is visible. In the middle region of the figure, an empty insertion compartment for a module housing 8 is shown on the support frame 3 to illustrate the attachment mechanism of the module housing 8. Again, the vertically arranged V-shaped portions 23 of the support frame 3 are visible, which come into contact with the tapered side wall portions of the module housing 8 when the module housing 8 is inserted into the insertion compartment. Also visible are the four through holes 24 for receiving the insertion pins 18 of the module housing 8, which are arranged in parallel to the display surface oriented rails 26 of the support frame 3.

Zur Befestigung eines eingeschobenen Modulgehäuses 8 dienen drei Einrastmittel 28, die im vorliegenden Beispielsfall als am V-förmigen Abschnitt des Tragrahmens 3 befestigte Rastzungen ausgebildet sind, die Ausnehmungen 30 zur Aufnahme der Haltenasen 16 aufweisen und in ihrem vorderen Randabschnitt 32 jeweils nach außen abgewinkelt, d.h. von der festzulegenden Seitenwand des Modulgehäuses wegragend, verlaufen. Die Befestigung der Rastzungen 28 am Tragrahmen 3 erfolgt üblicherweise mittels Verschrauben oder Vernieten. Die Rastzungen 28 erstrecken sich im wesentlichen senkrecht zur Anzeigefläche, und der Abstand zwischen Rastzungen gegenüberliegender Seiten entspricht im wesentlichen der Breite des Grundkörpers 12 eines Modulgehäuses 8.To fasten an inserted module housing 8 serve three latching means 28 which are formed in the present example as fixed to the V-shaped portion of the support frame 3 locking tongues having the recesses 30 for receiving the retaining lugs 16 and angled in its front edge portion 32 each outwardly, ie projecting from the side wall of the module housing to be defined. The attachment of the locking tongues 28 on the support frame 3 is usually carried out by means of screwing or riveting. The locking tongues 28 extend substantially perpendicular to the display surface, and the distance between locking tongues opposite sides substantially corresponds to the width of the base body 12 of a module housing eighth

Im dargestellten bevorzugten Ausführungsbeispiel ist zur Befestigung der linken Seitenwand des Modulgehäuses 8 eine Rastzunge vorgesehen, die sich im wesentlichen auf halber Höhe des Einschubfachs befindet. Zur Befestigung der gegenüberliegenden, rechten Seitenwand des Modulgehäuses 8 sind zwei Rastzungen vorgesehen, die sich im Bereich des oberen bzw. unteren Endes des Einschubfachs befinden. Diese Dreipunktgeometrie ist bei minimalem konstruktiven Aufwand besonders für eine sichere Befestigung der Modulgehäuse 8 geeignet. Es sind auch verschiedenste Anordnungen mit drei oder mehr Rastzungen 28 pro Modulgehäuse 8 denkbar. Hierbei ist jedoch darauf zu achten, dass die Rastzungen 28 einander zugewandter Seitenwände asymmetrisch, d.h. versetzt zueinander, angeordnet sind, da ansonsten keine unmittelbare Aneinanderreihung der Modulgehäuse 8 möglich wäre. Auch wenn die Rastzungen 28 hier links und rechts im Einschubfach angeordnet sind, ist es ebenso denkbar sie oben oder unten im Einschubfach anzuordnen, oder auch auf allen vier Seiten des Einschubfachs.In the illustrated preferred embodiment, a latching tongue is provided for fastening the left side wall of the module housing 8, which is located substantially at half the height of the insertion compartment. To attach the opposite, right side wall of the module housing 8, two locking tongues are provided, which are located in the region of the upper or lower end of the insertion compartment. This three-point geometry is particularly suitable for secure attachment of the module housing 8 with minimal design effort. There are also various arrangements with three or more locking tongues 28 per module housing 8 conceivable. It should be noted, however, that the locking tongues 28 facing each other side walls asymmetrically, i. offset from one another, are arranged, since otherwise no direct juxtaposition of the module housing 8 would be possible. Even if the locking tongues 28 are arranged here on the left and right in the insertion compartment, it is also conceivable to arrange them at the top or bottom in the insertion compartment, or also on all four sides of the insertion compartment.

Die Dimensionierung der Modulgehäuse ist nahezu frei wählbar, geeignet sind beispielsweise Modulgehäuse mit Anzeigefeldern von 210 x 150 mm, 320 x 230 mm oder 455 x 325 mm. Im hinteren Bereich des Einschubfachs können Federzungen 34 zur Abstützung des eingeschobenen Modulgehäuses 8 vorgesehen sein, die hier einstückig mit den Rastzungen 28 ausgebildet sind.The dimensioning of the module housing is almost freely selectable, suitable, for example, module housing with display fields of 210 x 150 mm, 320 x 230 mm or 455 x 325 mm. In the rear region of the insertion compartment spring tongues 34 may be provided for supporting the inserted module housing 8, which are formed here in one piece with the locking tongues 28.

In Fig. 6 ist ein erfindungsgemäßes Werkzeug 40 zum Lösen und Entfernen eines Modulgehäuses 8 von einem Tragrahmen 3 einer modularen Anzeigevorrichtung 1 dargestellt. Das Werkzeug 40 weist eine im wesentlichen dreieckige Grundplatte 42 auf, an der ein Griff 44 befestigt ist. Im Bereich der drei Ecken sind jeweils sich im wesentlichen senkrecht zur Grundplatte 42 erstreckende Mittel 46 zum Lösen der beweglichen Einrastmittel 28 von den entsprechenden Halteelementen 16 des Modulgehäuses 8 angeordnet. Die Lösemittel 46 sind in der bevorzugten Ausführungsform als dünne Blechstreifen ausgebildet, die in einem im wesentlichen rechten Winkel von der Grundplatte 42 abragen und in einem vorderen Mittelabschnitt 48 nach innen gebogen verlaufen, indem sie nach innen hin gekröpft sind. Am vorderen Ende der Lösemittel 46 ist jeweils ein Schuh 50 zum Eingriff in die Haltenase 16 eines Modulgehäuses 8 vorgesehen. Der Schuh 50 weist wie üblich zwei Zungen auf, die einen zwischen den Zungen angeordneten Einschnitt definieren, der sich vorzugsweise von innen zur Außenkante des Schuhs hin verbreitert. In dem länglichen Abschnitt zwischen vorderem Mittelabschnitt 48 und Grundplatte 42 weisen die Lösemittel 46 einen hinteren Mittelabschnitt 52 auf. In diesem Bereich ist auf einer nach innen gerichteten Fläche eine Blattfeder 54 angeordnet, die nach innen unter einem kleinen Winkel abragt und sich in Rückwärtsrichtung zur Grundplatte 42 hin erstreckt. Außerdem ist auf der in Fig. 6 nicht einsehbaren Frontseite der Grundplatte 42 mindestens ein Gummipuffer vorgesehen, der als Tiefenanschlag dient, um ein Beschädigen der Haltenasen 16 beim Einschieben des Werkzeugs 40 zu verhindern.FIG. 6 shows a tool 40 according to the invention for releasing and removing a module housing 8 from a support frame 3 of a modular display device 1. The tool 40 has a substantially triangular base plate 42 to which a handle 44 is attached. In the region of the three corners extending means 46 for releasing the movable latching means 28 are each arranged substantially perpendicular to the base plate 42 of the corresponding holding elements 16 of the module housing 8. The solvents 46 in the preferred embodiment are formed as thin sheet metal strips which protrude from the base plate 42 at a substantially right angle and are bent inwardly in a front center section 48 by being bent inwardly. At the front end of the solvent 46, a shoe 50 is provided for engagement in the retaining lug 16 of a module housing 8 respectively. The shoe 50 has, as usual, two tongues defining an incision disposed between the tongues, which preferably widened from the inside to the outer edge of the shoe. In the elongated portion between front middle portion 48 and base plate 42, the solvents 46 have a rear center portion 52. In this area, a leaf spring 54 is arranged on an inwardly directed surface, which protrudes inwardly at a small angle and extends in the rearward direction to the base plate 42 out. In addition, on the front side of the base plate 42, which is not visible in FIG. 6, at least one rubber buffer is provided which serves as a depth stop in order to prevent damage to the retaining lugs 16 when the tool 40 is inserted.

Die Anordnung der Lösemittel 46 entspricht der räumlichen Anordnung der Rastzungen 28 am Tragrahmen 3, so dass im vorliegenden Beispielsfalle an einer Seite des Werkzeugs 40 zwei Lösemittel angeordnet sind und an der gegenüberliegenden Seite ein Lösemittel 46 angeordnet ist. Natürlich ist es auch hier möglich, andere Geometrien auszuwählen, die der Anordnung der Rastzungen 28 entsprechen.The arrangement of the solvents 46 corresponds to the spatial arrangement of the latching tongues 28 on the support frame 3, so that in the present example case two solvents are arranged on one side of the tool 40 and a solvent 46 is arranged on the opposite side. Of course, it is also possible here to select other geometries that correspond to the arrangement of the locking tongues 28.

An dem einzelnen Lösemittel 46 ist ein Hebel 56 angeordnet, um das Werkzeug 40 von einem entnommenen Modulgehäuse 8 zu lösen, indem der Hebel gedrückt wird und sich der dünne Blechstreifen leicht nach oben verbiegt, wodurch die Blattfeder 54 über die Frontplatte 10 gehoben wird und somit das Modulgehäuse 8 nicht mehr in Eingriff mit dem Werkzeug 40 steht.At the single solvent 46, a lever 56 is arranged to release the tool 40 from a removed module housing 8 by the lever is pressed and the thin sheet metal strip bends slightly upwards, whereby the leaf spring 54 is lifted over the front panel 10 and thus the module housing 8 is no longer in engagement with the tool 40.

Im folgenden wird der Einsetzvorgang sowie der Entnahmevorgang eines Modulgehäuses 8 in die modulare Anzeigevorrichtung 1 dargestellt. Das Modulgehäuse 8 wird in das zugehörige Einschubfach des Tragrahmens 3 eingeschoben, wobei die vorderen Abschnitte 32 der drei Rastzungen 28 durch die Haltenasen 16 leicht nach außen gedrückt werden. Als Führung dienen hierbei zusätzlich die abgeschrägten Bereiche der Seitenwände 14 des Modulgehäuses 8, die mit den V-förmigen Abschnitten 23 des Tragrahmens 3 in Verbindung kommen, sowie die Einführstifte 18, die durch die Durchtrittslöcher 24 treten und somit eine exakte Anordnung des Modulgehäuses 8 ermöglichen. Wenn das Modulgehäuse 8 vollständig in das Einschubfach eingeschoben wird, rasten die Haltenasen 16 in die Ausnehmungen 30 der Rastzungen 28 ein, so dass das Modulgehäuse 8 sicher verankert ist. Im Anschluss daran können die notwendigen elektrischen/elektronischen Verbindungen zum Modulgehäuse 8 hergestellt werden.In the following, the insertion process and the removal process of a module housing 8 in the modular display device 1 is shown. The module housing 8 is inserted into the associated insertion compartment of the support frame 3, wherein the front portions 32 of the three locking tongues 28 are pressed by the retaining lugs 16 slightly outward. In this case additionally serve as a guide, the tapered portions of the side walls 14 of the module housing 8, which come into contact with the V-shaped portions 23 of the support frame 3, and the insertion pins 18 which pass through the through holes 24 and thus allow an exact arrangement of the module housing 8 , When the module housing 8 is fully inserted into the insertion compartment, the retaining lugs 16 engage in the recesses 30 of the locking tongues 28, so that the module housing 8 is securely anchored. Following this, the necessary electrical / electronic connections to the module housing 8 can be made.

Zum Entnehmen eines Modulgehäuses 8 aus dem Tragrahmen 3 werden die Lösemittel 46 des Werkzeugs 40 in die dafür vorgesehenen Ausnehmungen 22 der Frontplatte 10 eingesteckt und eingeschoben, wobei die Blattfedern 54 zusammengedrückt werden. Im Inneren greifen die Schuhe 50 in die Haltenasen 16 ein, und die Rastzungen 28 werden aufgrund der Kröpfung des vorderen Mittelabschnitts 48 der Lösemittel 46 nach außen gebogen, so dass sie nicht mehr in Eingriff mit den Haltenasen 16 stehen. Gleichzeitig rasten die Blattfedern 54 bei vollständigem Durchtritt durch die Ausnehmungen 22 an der Rückseite der Frontplatte 10 ein und dienen somit als Widerhaken bei der nach außen gerichteten Entnahmebewegung des Werkzeugs. Somit wird das Modulgehäuse 8 beim Herausnehmen vom Werkzeug 40 sicher umfasst und kann ohne weitere Hilfe herausgezogen werden. Die Federzungen 34 unterstützen mit ihrer nach außen gerichteten Federkraft die Entnahme des Modulgehäuses 8.For removing a module housing 8 from the support frame 3, the solvent 46th of the tool 40 inserted into the recesses 22 provided for this purpose of the front panel 10 and inserted, wherein the leaf springs 54 are compressed. Inside, the shoes 50 engage in the retaining lugs 16, and the locking tongues 28 are bent outwardly due to the cranking of the front central portion 48 of the solvent 46, so that they are no longer in engagement with the retaining lugs 16. At the same time, the leaf springs 54 engage in full passage through the recesses 22 at the back of the front panel 10 and thus serve as barbs in the outwardly directed removal movement of the tool. Thus, the module housing 8 is securely included in the removal of the tool 40 and can be pulled out without further assistance. The spring tongues 34 support the removal of the module housing 8 with their outwardly directed spring force.

Sobald das Modulgehäuse 8 aus dem Tragrahmen 3 entnommen ist, kann das Werkzeug 40 durch Drücken des Hebels 56 wieder vom Modulgehäuse 8 gelöst werden. Auf diese Weise ist ein besonders einfaches Einbauen und Austauschen von Modulgehäusen 8 möglich.Once the module housing 8 is removed from the support frame 3, the tool 40 can be released by pressing the lever 56 back from the module housing 8. In this way, a particularly simple installation and replacement of module housings 8 is possible.
