Fig. 1 zeigt eine Explosionsdarstellung einer Dachantenne für ein Fahrzeug mit einer Abdeckhaube 10, die mit einer Basisplatte 12 über eine Rasteinrichtung verbindbar ist und zwar derart, dass die Abdeckhaube 10 von oben und die Basisplatte 12 von unten auf eine Öffnung eines Fahrzeugdachs aufgesetzt und mit der Rasteinrichtung so miteinander verbunden werden, dass das Fahrzeugdach zwischen Abdeckhaube 10 und Basisplatte 12 geklemmt ist. Hierbei ist zur Abdichtung und zum Toleranzausgleich eine umlaufende flexible Dichtung 14 vorgesehen, die vor der Montage auf die Basisplatte 12 aufgesetzt wird und die nach der Montage gegen die Unterseite des Fahrzeugdaches gepresst wird. Fig. 1 shows an exploded view of a roof antenna for a vehicle with a cover 10, which can be connected to a base plate 12 via a locking device in such a way that the cover 10 is placed from above and the base plate 12 from below onto an opening in a vehicle roof and with the locking device can be connected to each other so that the vehicle roof is clamped between the cover 10 and the base plate 12. Here, for sealing and tolerance compensation, a circumferential flexible seal 14 is provided, which is placed on the base plate 12 before assembly and which is pressed against the underside of the vehicle roof after assembly.

Die Basisplatte 12 ist aus Metall hergestellt und dient zur Befestigung diverser elektronischer Bauteile und Antennen, die in den Figuren nicht dargestellt sind. Demgegenüber ist die Abdeckhaube 10 aus Kunststoff hergestellt und an ihrer Unterseite so konturiert, dass die Außenkontur der Abdeckhaube 10 dort im Wesentlichen der Außenkontur der Basisplatte 12 entspricht (vgl. Fig. 3).The base plate 12 is made of metal and is used to attach various electronic components and antennas that are not shown in the figures. In contrast, the cover 10 is made of plastic and is contoured on its underside in such a way that the outer contour of the cover 10 essentially corresponds to the outer contour of the base plate 12 (cf. Fig. 3 ).

Die Rasteinrichtung zur Verbindung von Abdeckhaube 10 und Basisplatte 12 umfasst einerseits Rasthaken 16, die einstückig an der Basisplatte angeformt sind. Andererseits sind im Inneren der Abdeckhaube entlang deren Umfang federnde Rastlaschen 18 in im Wesentlichen gleichen Abständen angeformt, die im zusammengebauten Zustand von den Rasthaken 16 hintergriffen werden.The locking device for connecting the cover 10 and base plate 12 includes, on the one hand, locking hooks 16, which are integrally formed on the base plate. On the other hand, inside the cover, resilient locking tabs 18 are formed along its circumference at essentially equal intervals, which are gripped behind by the locking hooks 16 in the assembled state.

Jede Rastlasche 18 weist zwei Schenkel 20 und 22 auf, die an ihren äußeren Enden über einen Quersteg 24 miteinander verbunden sind. Hierbei ist der Quersteg 24 spitz zulaufend ausgebildet, so dass jede Rastlasche 18 an ihrem vorderen Ende eine Schneide ausbildet, um das Einführen eines Werkzeugs zur Lösung des Hintergriffs zu erleichtern. Wie Fig. 10 weiter verdeutlicht, sind im Inneren der Abdeckhaube 10 insbesondere neben den Rastlaschen 18 mehrere Stützrippen 26 vorgesehen, die einerseits die Außenwand der Abdeckhaube 10 versteifen, die andererseits jedoch auch dazu dienen, gerade im Bereich der Rastverbindungen eine Auflage für die Basisplatte 12 zu bilden, um eine stabile Verbindung von Abdeckhaube 10 und Basisplatte 12 zu erreichen.Each locking tab 18 has two legs 20 and 22, which are connected to one another at their outer ends via a crossbar 24. Here, the crossbar 24 is tapered, so that each locking tab 18 forms a cutting edge at its front end in order to make it easier to insert a tool to release the rear grip. 10 further illustrates, in the interior of the cover 10, in particular next to the locking tabs 18, several support ribs 26 are provided, which on the one hand stiffen the outer wall of the cover 10, but on the other hand also serve to provide a support for the base plate 12, especially in the area of the locking connections to form in order to achieve a stable connection between the cover 10 and the base plate 12.

Wie Fig. 1 und Fig. 3 zeigen, sind an der Basisplatte 12 im Bereich der Rasthaken 16 Aussparungen 30 und 32 vorgesehen, die einen Eingriff eines Werkzeugs zum Lösen des Hintergriffs zwischen Rasthaken 16 und Rastlasche 18 ermöglichen. Hierbei sind die Aussparungen 30 im Bereich der Rasthaken 16 am Außenumfang der Basisplatte 12 vorgesehen und öffnen sich zum Außenrand, während die Aussparungen 32 am vorderen und hinteren Ende der Basisplatte 12 allseitig geschlossen sind. Alle Aussparungen 30 und 32 besitzen eine Breite, die etwa dem Abstand der beiden Schenkel 20 und 22 bzw. der Breite des Querstegs 24 entspricht, so dass durch die Aussparungen ein Werkzeug eingeführt werden kann, welches die Schenkel 20 und 22 federnd zurückbiegt, um den Hintergriff zwischen Rasthaken 16 und Rastlasche 18 zu lösen.How Fig. 1 and Fig. 3 show, recesses 30 and 32 are provided on the base plate 12 in the area of the latching hooks 16, which enable a tool to engage to release the rear grip between the latching hook 16 and the latching tab 18. Here, the recesses 30 are provided in the area of the locking hooks 16 on the outer circumference of the base plate 12 and open towards the outer edge, while the recesses 32 at the front and rear ends of the base plate 12 are closed on all sides. All recesses 30 and 32 have a width that corresponds approximately to the distance between the two legs 20 and 22 or the width of the crossbar 24, so that a tool can be inserted through the recesses which resiliently bends the legs 20 and 22 back in order to Release the rear grip between the locking hook 16 and the locking tab 18.

Damit ein Werkzeug auch störungsfrei durch die Dichtung 14 hindurchgeführt werden kann, sind in der Dichtung im Bereich der Rasthaken allseitig geschlossene Öffnungen 34 vorgesehen, durch die sich einerseits jeweils ein Rasthaken 16 und andererseits ein Werkzeug erstrecken kann.So that a tool can be passed through the seal 14 without any problems, openings 34 that are closed on all sides are provided in the seal in the area of the locking hooks, through which a locking hook 16 and a tool can extend.

Zur Montage der vorstehend beschriebenen Dachantenne an einem Fahrzeugdach wird zunächst die Dichtung 14 auf die Basisplatte 12 aufgesetzt, wobei sich die Rasthaken 16 durch die Öffnungen 34 erstrecken. Anschließend wird die Abdeckhaube 10 von oben auf eine Öffnung des Fahrzeugdaches aufgesetzt, so dass die Einheit aus Basisplatte 12 und Dichtung 14 von unten in die Abdeckhaube 10 eingesetzt werden kann und dabei die Rasthaken 16 die federnden Rastlaschen 18 hintergreifen (vgl. Fig. 3). Soll für Reparatur oder Austausch die Dachantenne wieder von dem Fahrzeug gelöst werden, kann in die Aussparungen 30, 32 der Basisplatte 12 ein Werkzeug 40 eingesetzt werden, wie es rein beispielhaft in Fig. 4 dargestellt ist. Das Werkzeug 40 ist aus einer kleinen Metallplatte gefertigt, die zwei an einem Ende eines Steges 42 und 44 vorgesehene Klingen 46 und 48 umfasst, wobei die beiden Klingen 46 und 48 bzw. die beiden Stege 42 und 44 im Abstand der Schenkel 20 und 22 der Rastlaschen 18 beabstandet sind. Hierdurch lässt sich das Werkzeug 40 von der Unterseite der Basisplatte 12 mit den Klingen 46 und 48 zwischen dem Quersteg 24 und der Basisplatte 12 so einführen, dass die Rastlasche 18 gebogen wird und sich der Hintergriff mit dem Rasthaken 16 löst. Wenn in alle oder nahezu alle Aussparungen 30 und 32 ein Werkzeug 40 entsprechend eingesetzt ist, lässt sich die Basisplatte 12 zerstörungsfrei von der Abdeckhaube 10 lösen. Es versteht sich, dass auch lediglich ein einziges Werkzeug vorgesehen sein kann, das in alle oder nahezu alle Aussparungen 30 und 32 gleichzeitig eingreift.To mount the roof antenna described above on a vehicle roof, the seal 14 is first placed on the base plate 12, whereby the locking hooks 16 extend through the openings 34. The cover 10 is then placed from above onto an opening in the vehicle roof, so that the unit consisting of base plate 12 and seal 14 can be inserted into the cover 10 from below and the locking hooks 16 engage behind the resilient locking tabs 18 (cf. Fig. 3 ). If the roof antenna is to be detached from the vehicle again for repair or replacement, a tool 40 can be inserted into the recesses 30, 32 in the base plate 12, as shown purely by way of example Fig. 4 is shown. The tool 40 is made of a small metal plate which comprises two blades 46 and 48 provided at one end of a web 42 and 44, the two blades 46 and 48 or the two webs 42 and 44 being at a distance from the legs 20 and 22 of the Locking tabs 18 are spaced apart. This allows the tool 40 to be inserted from the underside of the base plate 12 with the blades 46 and 48 between the crossbar 24 and the base plate 12 in such a way that the locking tab 18 is bent and the rear grip with the locking hook 16 is released. If a tool 40 is inserted into all or almost all of the recesses 30 and 32, the base plate 12 can be removed from the cover 10 without being destroyed. It goes without saying that only a single tool can be provided, which engages in all or almost all of the recesses 30 and 32 at the same time.
