Description

Die Erfindung betrifft ein Signalgerät nach dem Oberbegriff des Anspruchs 1.The invention relates to a signaling device according to the preamble of claim 1.

Im Handel sind sogenannte Signalleuchten bekannt, die aus einem Sockelelement und einer Kalotte bestehen. Diese Gehäuseelemente werden in der Regel separat gefertigt und zusammengesetzt. Im Sockel befinden sich in der Regel die elektrischen Anschlusselemente an eine externe Stromversorgung und bei Bedarf an eine externe Steuerung.So-called signal lights are known in the trade and consist of a base element and a dome. These housing elements are usually manufactured and assembled separately. The base usually contains the electrical connection elements to an external power supply and, if necessary, to an external control.

Weiterhin sind beispielsweise durch die Druckschriften EP 3 174 021 A1 und WO 95/28598 Signalsäulen bekannt, bei denen die Kalotte aus mehreren Gehäuseelementen für mehrere Segmente für unterschiedliche Signalelemente, z. B. um verschiedene Farbsignale oder auch akustische Signalelemente zu kombinieren. Solche Gehäuseelemente der Segmente, die entlang einer Längsachse des Signalgerätes zueinander benachbart angeordnet sind, weisen Trennelemente auf, die als Abtrennung quer zur Längsachse angeordnet sind. Diese Trennelemente dienen zur Abschattung der Segmente untereinander und zur Befestigung eines Etikettes.Furthermore, for example, through the publications EP 3 174 021 A1 and WO 95/28598 Signal towers are known in which the dome consists of several housing elements for several segments for different signal elements, e.g. B. to combine different color signals or acoustic signal elements. Such housing elements of the segments, which are arranged adjacent to one another along a longitudinal axis of the signaling device, have separating elements which are arranged as a separation transversely to the longitudinal axis. These separating elements serve to shade the segments from one another and to attach a label.

Im Handel sind Signalsäulen mit separat gefertigten und mit den Gehäuseelementen von Segmenten verbundenen Trennelementen bekannt, die ebenfalls zur Abschattung der Segmente untereinander und zur Befestigung eines Etikettes dienen.Signal towers with separately manufactured separating elements connected to the housing elements of segments are known in the trade, which also serve to shade the segments from one another and to attach a label.

Die oben genannten Trennelemente bestehen aus Hartplastik, wobei für die Abdichtung der Segmente nach außen ein O-Ring als Dichtung im Bereich der Verbindungsstelle der Gehäuseelemente vorgesehen ist.The above-mentioned separating elements are made of hard plastic, with an O-ring being provided as a seal in the area of the connection point of the housing elements to seal the segments from the outside.

Aufgabe der Erfindung ist es demgegenüber, ein verbessertes Trennelement vorzuschlagen.The object of the invention is, in contrast, to propose an improved separating element.

Diese Aufgabe wird ausgehend von einem Signalgerät nach dem Oberbegriff des Anspruchs 1 durch dessen Kennzeichen gelöst.This task is based on a signaling device according to the preamble of claim 1 solved by its identifier.

Dementsprechend zeichnet sich ein erfindungsgemäßes Signalgerät dadurch aus, dass das Trennelement wenigstens teilweise aus Elastomer geformt ist. Durch diese Materialwahl sind verschiedene, auch neue Funktionen des Trennelementes zu realisieren, für die bislang separate Bauelemente mit entsprechender Montage erforderlich waren.Accordingly, a signaling device according to the invention is characterized in that the separating element is at least partially formed from elastomer. This choice of material makes it possible to realize various, including new, functions of the separating element, for which separate components with appropriate assembly were previously required.

So kann beispielsweise an einem derartigen aus Elastomer geformten Bereich des Trennelementes in einfacher Weise maschinell eine Beschriftung oder sonstige Information angebracht werden. Dies kann z. B. mittels eines Lasers vorgenommen und ggf. spezifisch für jedes einzeln gefertigte Teil erfolgen. Das Anbringen einer solchen Information ist auf Hartplastik erschwert, weshalb bislang separat gefertigte Etiketten unter entsprechendem Fertigungs- und Montageaufwand verwendet werden.For example, a label or other information can easily be attached mechanically to such an elastomer-shaped area of the separating element. This can e.g. B. carried out using a laser and, if necessary, specifically for each individually manufactured part. Attaching such information is difficult on hard plastic, which is why previously separately manufactured labels have been used with corresponding manufacturing and assembly effort.

Ein erfindungsgemäßes Trennelement kann auch in dem aus Elastomer geformten Bereich für sichtbares Licht intransparent ausgebildet werden, um die gegenseitige Abschattung zwischen einzelnen Gehäuseelementen des Signalgerätes, insbesondere von Segmenten einer Signalsäule zu bewirken.A separating element according to the invention can also be made non-transparent to visible light in the area formed from elastomer in order to effect mutual shading between individual housing elements of the signaling device, in particular segments of a signal tower.

Zudem eignet sich ein erfindungsgemäßer aus Elastomer geformten Bereich des Trennelementes auch zur Ausformung einer integrierten Dichtung, beispielsweise einer Lippendichtung, wodurch sich die separate Anordnung und Montage eines O-Rings beispielsweise in einer eigens dafür vorzusehenden Nut erübrigt.In addition, an elastomer-shaped area of the separating element according to the invention is also suitable for forming an integrated seal, for example a lip seal, which makes the separate arrangement and assembly of an O-ring, for example in a groove to be provided specifically for this purpose, unnecessary.

Alle Vorteile eines solchen aus Elastomer geformten Bereichs des Trennelementes können für sich oder in Kombination untereinander in einem erfindungsgemäßen Trennelement verwirklicht werden.All the advantages of such an elastomer-shaped area of the separating element can be realized individually or in combination with one another in a separating element according to the invention.

Vorteilhafterweise weist das Trennelement hierzu eine quer zur Längsachse ausgerichtete, wenigstens teilweise aus Elastomer geformte Fläche auf, mit der sich die gegenseitige Abschattung der Gehäuseelemente und/oder das Anbringen einer gut sichtbaren Information besonders gut verwirklichen lassen.For this purpose, the separating element advantageously has a surface which is oriented transversely to the longitudinal axis and is at least partially formed from elastomer, with which the mutual shading of the housing elements and/or the attachment of clearly visible information can be achieved particularly well.

Vorzugsweise wird eine in dem aus Elastomer geformten Bereich des Trennelementes angebrachte Information, insbesondere durch Beschriftung oder Kodierung, z. B. durch einen QR-Kode, mittels eines steuerbaren Werkzeugs wie ein Laser angebracht. Dadurch ist das Anbringen der Information bei der Fertigung des Trennelementes ohne weitere Kennzeichnungselemente möglich. Insbesondere wird das Anbringen einer individuellen, teilespezifische Information durch diese Maßnahme vereinfacht.Preferably, information attached to the elastomer-shaped area of the separating element, in particular by labeling or coding, e.g. B. attached by a QR code using a controllable tool such as a laser. This makes it possible to attach the information during the production of the separating element without additional identification elements. In particular, this measure simplifies the attachment of individual, part-specific information.

Diese Information kann auf einer dafür vorgesehenen Beschriftungsfläche, z.B. auf der o.a. quer zur Längsachse ausgerichteten, wenigstens teilweise aus Elastomer geformten Fläche angebracht werden.This information can be attached to a designated labeling surface, e.g. on the above-mentioned surface oriented transversely to the longitudinal axis and at least partially formed from elastomer.

Zur Verwendung des Trennelementes für die gegenseitige Beschattung der Gehäuseelemente weist dieses bevorzugt eine durchgehende Trennfläche auf, die von wenigstens einer Ausnehmung für wenigstens ein Anschlusselement zum elektrischen Anschluss eines im benachbarten Gehäuseelement angeordneten Signalelement unterbrochen sein kann. Für die Beschattung ist eine durchgehende lichtabsorbierende oder lichtreflektierende Fläche von Vorteil, wobei aus funktionellen Gründen das oder die Anschlusselemente für die in einem benachbarten Gehäuseelement untergebrachten Signalelemente durch das Trennelement hindurchgeführt werden können. Da diese Trennfläche in der Regel gut einsehbar ist, eignet sie sich zugleich für eine gut sichtbare Information oder Beschriftung.To use the separating element for mutual shading of the housing elements, it preferably has one continuous separating surface, which can be interrupted by at least one recess for at least one connection element for the electrical connection of a signal element arranged in the adjacent housing element. A continuous light-absorbing or light-reflecting surface is advantageous for shading, and for functional reasons the connection element or elements for the signal elements housed in an adjacent housing element can be passed through the separating element. Since this dividing surface is usually easy to see, it is also suitable for clearly visible information or labeling.

Die Anschlusselemente können diese Ausnehmungen in montiertem Zustand verschließen und so zur Verschattung beitragen. Das oder die Anschlusselemente können vielfältig ausgestaltet sein, beispielsweise als Einzelkontakt, insbesondere als Kontaktfeder, oder als durch die Gehäuseelemente hindurchragende Leiterplatte.The connecting elements can close these recesses when installed and thus contribute to shading. The connection element or elements can be designed in a variety of ways, for example as an individual contact, in particular as a contact spring, or as a circuit board protruding through the housing elements.

Weiterhin kann das Trennelement, wie bereits erwähnt, an einem Außenumfang eine ringförmige, aus Elastomer angeformte Dichtung, beispielsweise eine radial dichtende Dichtung, insbesondere in Form einer radial dichtenden Lippendichtung aufweisen.Furthermore, as already mentioned, the separating element can have an annular seal formed from elastomer on an outer circumference, for example a radially sealing seal, in particular in the form of a radially sealing lip seal.

Durch die Formung der Dichtung in das Trennelement vermindert sich der Fertigungs-und Montageaufwand erheblich. Im Falle der Ausbildung als Lippendichtung ergibt sich zusätzlich eine verminderte Reibung zwischen den zu verbindenden Gehäuseelementen bei eine relativen Drehung zueinander um die Längsachse, die bei vielen Verbindungsmechanismen wie Bajonettverschlüssen oder dergleichen erforderlich ist.By forming the seal into the separating element, the manufacturing and assembly effort is significantly reduced. In the case of the design as a lip seal, there is also reduced friction between the housing elements to be connected when they rotate relative to one another about the longitudinal axis, which is required in many connection mechanisms such as bayonet locks or the like.

Zur mechanischen Stabilisierung kann das Trennelement ein Stützelement aus Hartplastik zum Abstützen des aus Elastomer geformten Bereichs umfassen. Insbesondere kann das Trennelement hierzu in einem Mehrkomponenten-Verfahren, insbesondere einem sogenannten 2-K Verfahren aus Hartplastik und Elastomer geformt werden.For mechanical stabilization, the separating element can have a support element made of hard plastic to support the elastomer include shaped area. In particular, the separating element can be formed from hard plastic and elastomer in a multi-component process, in particular a so-called 2-component process.

Das Trennelement kann an ein Gehäuseelement zu einem Stück angeformt werden, was insbesondere bei großen Stückzahlen von Vorteil ist. Es kann aber auch als separat gefertigtes Bauteil mit dem Gehäuseelement verbindbar sein, wodurch beispielsweise verschiedene Trennelemente bei gleich geformten Gehäuseelementen oder gleiche Trennelemente bei verschieden ausgebildeten Gehäuseelementen verwendbar sind.The separating element can be molded onto a housing element in one piece, which is particularly advantageous for large quantities. However, it can also be connectable to the housing element as a separately manufactured component, whereby, for example, different separating elements can be used with housing elements of the same shape or the same separating elements with differently designed housing elements.

Wie bereits erwähnt kann ein erfindungsgemäßes Signalgerät eine Signalsäule mit einer aus verschiedenen Segmentelementen gebildeten mehrteiligen Kalotte oder eine Signalleuchte mit einem Gehäuse aus einer einteiligen Kalotte und einem Sockelelement sein.As already mentioned, a signaling device according to the invention can be a signal tower with a multi-part dome formed from various segment elements or a signal light with a housing made of a one-piece dome and a base element.

Das beschriebene Trennelement kann also ebenso zur Trennung eines Sockels von einer Kalotte wie zur Trennung einzelner Gehäuseelemente einer mehrteiligen Kalotte aus mehreren Segmenten, z. B. einer Signalsäule sein.The separating element described can also be used to separate a base from a dome as well as to separate individual housing elements of a multi-part dome made of several segments, e.g. B. be a signal tower.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird anhand der Figuren nachfolgend näher erläutert.An exemplary embodiment of the invention is shown in the drawing and is explained in more detail below with reference to the figures.

  • Fig.3 a sectional view of two housing elements of a signal tower on a base element Fig.1 and
  • Fig. 4 one Fig. 1 Corresponding representation of a base element with a modified separating element.

Das Sockelelement 1 in Fig. 1 umfasst ein Sockelgehäuse 2 mit einem oberen Trennelement 3. Das Trennelement 3 ist einstückig mit dem Sockelgehäuse 2 ausgebildet und umfasst ein Unterteil 4, das ein Stützelement für ein Oberteil 5 bildet. Dementsprechend ist das Unterteil 4 aus dem gleichen Hartplastik wie das Sockelgehäuse gebildet, während das Oberteil 5 erfindungsgemäß aus einem Weichplastik oder Elastomer gebildet ist. Das gesamte Sockelelement 1 kann in einem 2-Komponenten-Verfahren am Stück in einer Form gespritzt werden.The base element 1 in Fig. 1 comprises a base housing 2 with an upper separating element 3. The separating element 3 is formed in one piece with the base housing 2 and includes a lower part 4, which forms a support element for an upper part 5. Accordingly, the lower part 4 is formed from the same hard plastic as the base housing, while the upper part 5 according to the invention is formed from a soft plastic or elastomer. The entire base element 1 can be injected in one piece in a mold using a 2-component process.

Das Oberteil 5 weist eine durchgehende Oberfläche 6 auf, die nur durch eine Ausnehmung 7 für Kontaktelemente unterbrochen ist. Die bei jedem einzelnen Gehäuseelement gut sichtbare Oberfläche 6 kann mit einem ansteuerbaren Werkzeug wie einem Laser oder dergleichen beschriftet oder auf sonstige Weise markiert oder gekennzeichnet werden. In diesem Fall bildet die Oberfläche 6 eine Beschriftungsfläche 9.The upper part 5 has a continuous surface 6, which is only interrupted by a recess 7 for contact elements. The surface 6, which is clearly visible on each individual housing element, can be labeled or marked or identified in some other way using a controllable tool such as a laser or the like. In this case, the surface 6 forms a labeling area 9.

Das aus Elastomer gebildete Oberteil 5 ist für sichtbares Licht intransparent, so dass die benachbart angeordneten Gehäuseelemente 11,12 gegeneinander verschattet sind.The upper part 5 made of elastomer is opaque to visible light, so that the housing elements 11, 12 arranged adjacently are shaded from one another.

Am Rand des Oberteils 5 ist eine Lippendichtung 8 angebracht, die radial an einem Innenumfang eines entlang einer Längsachse A darüber gesteckten, benachbart angeordneten Gehäuseelementes 11,12 dichtet.A lip seal 8 is attached to the edge of the upper part 5, which seals radially on an inner circumference of a housing element 11, 12 arranged adjacently and placed above it along a longitudinal axis A.

In Fig. 1 sind weiterhin einzelne Aufnahmen 10 für nicht dargestellte Aderendhülsen elektrischer, extern zuzuführender Anschlusskabel und nicht dargestellte Kontaktfedern zu sehen, die zum elektrischen Anschluss von in benachbarten Gehäuseelementen 2,11,12, z.B. auf Leiterplatten 13,14, untergebrachten Signalelementen angebracht werden können.In Fig. 1 Individual receptacles 10 can also be seen for ferrules, not shown, of electrical, externally supplied connection cables and contact springs, not shown, which can be attached for the electrical connection of signal elements housed in adjacent housing elements 2, 11, 12, for example on circuit boards 13, 14.

In Fig. 3 sind Gehäuseelemente 11,12 benachbarter Kalottensegmente zu erkennen, in denen die Leiterplatten 13,14 liegen. Die Leiterplatten 13,14 werden über Kontaktfedern 15 kontaktiert. Die Leiterplatten 13,14 tragen in dieser Ausführung die Signalelemente, wie Leuchtmittel oder akustische Warnmittel, beispielsweise Lampen, LED, Piezo-Summer, Hupen oder dergleichen.In Fig. 3 Housing elements 11, 12 of adjacent dome segments can be seen, in which the circuit boards 13, 14 are located. The circuit boards 13, 14 are contacted via contact springs 15. In this version, the circuit boards 13, 14 carry the signaling elements, such as lamps or acoustic warning devices, for example lamps, LEDs, piezo buzzers, horns or the like.

Die Gehäuseelemente 11,12 und das Sockelgehäuse 2 werden über Bajonettverschlüsse 16,17 miteinander verbunden, bei denen jeweils Nocken 18 eines Gehäuseelementes in zugehörige Nuten 19 eines benachbarten Gehäuseelementes eingreifen. Dabei dichtet die Lippendichtung 8 des jeweiligen Oberteils 5 eines Gehäuseelementes 11 radial gegenüber einem Innenumfang 20 des nächsten Gehäuseelementes 12 ab. Auf diese Weise entfallen separate Dichtungen wie O-Ringe und das aus dem Sockelgehäuse und den weiteren Gehäuseelementen bestehende Gesamtgehäuse wird je nach Anforderung gegen Staub und/oder Feuchtigkeit gedichtet. Zusätzlich bietet die Lippendichtung 8 gegenüber einem O-Ring erheblich weniger Reibungswiderstand beim Drehen eines Bajonettverschlusses 16,17. In Figur 3 ist zudem erkennbar, dass in den Gehäuseelementen 11,12 jeweils ein Diffusor 21 als Einsatz angebracht ist, mit dem das Leuchtbild des jeweiligen Kalottensegmentes ausgestaltet wird.The housing elements 11, 12 and the base housing 2 are connected to one another via bayonet locks 16, 17, in which cams 18 of one housing element engage in associated grooves 19 of an adjacent housing element. The lip seal 8 of the respective upper part 5 of a housing element 11 seals radially from an inner circumference 20 of the next housing element 12. In this way, separate seals such as O-rings are eliminated and the entire housing, which consists of the base housing and the other housing elements, is sealed against dust and/or moisture, depending on requirements. In addition, the lip seal 8 offers significantly less frictional resistance when turning a bayonet lock 16,17 compared to an O-ring. In Figure 3 It can also be seen that a diffuser 21 is attached as an insert in the housing elements 11, 12, with which the illuminated image of the respective dome segment is designed.

Die Ausführung nach Fig. 4 entspricht weitgehend der Ausführung nach Fig. 2, wobei nunmehr die Lippendichtung gegenüber der Längsachse entgegengesetzt geneigt ausgebildet ist.The execution according to Fig. 4 largely corresponds to the execution Fig. 2 , whereby the lip seal is now designed to be inclined in the opposite direction relative to the longitudinal axis.
