Description

Die Erfindung betrifft eine Antennenanordnung sowie ein Verfahren zum Betreiben einer solchen Antennenanordnung gemäß den Merkmalen der jeweiligen Oberbegriffe der unabhängigen Patentansprüche.The invention relates to an antenna arrangement and a method for operating such an antenna arrangement according to the features of the respective preambles of the independent claims.

Antennenanordnungen für Fahrzeuge, die auf einer Oberfläche des Fahrzeuges montiert werden, sind grundsätzlich bekannt. Sehr weit verbreitet bei Fahrzeugen sind Dachantennen, bei denen eine solche Dachantenne eine Bodenplatte sowie eine Abdeckung aufweist, wobei unter der Abdeckung Antennenelemente zum Empfangen und/oder Senden hochfrequenter Signale verschiedener Dienst (wie beispielsweise Telefon, Fernsehen, Navigation und dergleichen) angeordnet sind. Diese Dachantenne wird auf dem Dach (oder gegebenenfalls auf einem anderen Karosserieteil des Fahrzeuges) dadurch montiert, dass von der Bodenplatte nach unten ein Gewindezapfen absteht, wobei der Gewindezapfen durch eine Öffnung in dem Karosserieteil durchgeführt wird und danach von unten eine Befestigungsmutter auf den Gewindezapfen aufgeschraubt wird, sodass dadurch die Dachantenne dauerhaft in ihrer Lage fixiert ist. Anschließend erfolgt in ebenfalls an sich bekannter Weise die Verkabelung der Dachantenne mit nachgeschalteten elektronischen Geräten, beispielsweise zur Wiedergabe der Empfangenen Signale. Diese Anordnung sowie deren Montage sind aufwändig, da sie immer von zwei Personen durchgeführt werden müssen.Antenna arrangements for vehicles mounted on a surface of the vehicle are basically known. Very widely used in vehicles are roof antennas in which such a roof antenna has a bottom plate and a cover, wherein under the cover antenna elements for receiving and / or transmitting high-frequency signals of different service (such as telephone, television, navigation and the like) are arranged. This roof antenna is mounted on the roof (or optionally on another body part of the vehicle) by projecting downwardly from the bottom plate a threaded pin, the threaded pin being passed through an opening in the body part and then screwed from below a fastening nut on the threaded pin so that the roof antenna is permanently fixed in position. Subsequently, in a manner known per se, the wiring of the roof antenna with downstream electronic devices, for example, to reproduce the received signals. This arrangement and their installation are complex because they must always be performed by two people.

Um dieses Problem zu umgehen, sind schon verschiedene Antennenanordnungen bekannt geworden, die so gestaltet sind, dass sie von oben auf das Dach aufgesetzt, vorfixiert und anschließend endfixiert werden können, wobei hierfür nur eine einzige Person erforderlich ist. Stellvertretend für diesen Stand der Technik steht beispielsweise die DE 10 2005 044 610 A1 .To circumvent this problem, various antenna arrangements are already known, which are designed so that they can be placed from above on the roof, pre-fixed and then endfixed, for which only a single person is required. Representative of this state of the art is, for example, the DE 10 2005 044 610 A1 ,

Allerdings haben auch diese Ausgestaltungen von Antennenanordnungen den Nachteil, dass sie hinsichtlich ihrer Konstruktion und der mehreren nacheinander auszuführenden Montageschritte aufwändig sind. Weiteren Stand der Technik bilden US2011/0267243A1 , US2011/0017899 A1 , US2008/0131199A1 und JP2009017329A .However, these embodiments of antenna arrangements have the disadvantage that they are complex in terms of their construction and the several successive assembly steps to be performed. Form further state of the art US2011 / 0267243A1 . US2011 / 0017899 A1 . US2008 / 0131199A1 and JP2009017329A ,

Der Erfindung liegt daher die Aufgabe zugrunde, eine Antennenanordnung sowie ein Verfahren zum Betreiben einer solchen Antennenanordnung bereitzustellen, das hinsichtlich der Konstruktion einfach gestaltet und hinsichtlich der Montage einfach zu betreiben ist. Dabei soll letztendlich sichergestellt werden, dass die Montage von nur einer Person ausgeführt werden kann und nach der Montage die Antennenanordnung sachgerecht und dauerhaft montiert ist.The invention is therefore based on the object to provide an antenna arrangement and a method for operating such an antenna arrangement, which is simple in terms of construction and easy to operate with respect to the assembly. It should ultimately be ensured that the assembly can be performed by only one person and after installation, the antenna assembly is properly and permanently mounted.

Diese Aufgabe ist durch die Merkmale der unabhängigen Patentansprüche gelöst.This object is solved by the features of the independent claims.

Hinsichtlich der konstruktiven Ausgestaltung der Antennenanordnung ist erfindungsgemäß unter Anderem vorgesehen, dass die Befestigungsmittel als eine zumindest zwei etwa in V-Form zueinander ausgerichtete und von einem Gegenhalter aus sich erstreckende und an der Bodenplatte befestigbare Spreizschenkel aufweisende Befestigungskralle ausgebildet sind. Die beiden miteinander verbundenen oder verbindbaren Spreizschenkel sind dabei so gestaltet, dass sie einerseits durch eine Öffnung in dem Karosserieteil durchführbar sind und andererseits nach der Durchführung eine Vorverrastung (Vorfixierung) der Antennenanordnung ermöglichen. In diesem Fall ist unter Antennenanordnung dasjenige Gebilde zu verstehen, welches auf bzw. an dem Karosserieteil des Fahrzeuges, insbesondere auf dessen Dach, angeordnet und in seiner Lage fixiert werden soll. Die beiden Spreizschenkel bilden in ihrem Verbindungsbereich eine Art Vorsprung, der es gestattet, die Antennenanordnung an dem Karosserieteil in seiner Lage vorzufixieren, nachdem der untere Befestigungsbereich der Antennenanordnung durch die Öffnung in dem Karosserieteil durchgeführt wurde. Anschließend erfolgt eine weitere Verformung der beiden Spreizschenkel zueinander, sodass der Winkel der V-Form verkleinert wird. Dadurch wird gewährleistet, dass die Bodenplatte der Antennenanordnung flächig und dauerhaft auf der Oberfläche des Karosserieteiles zur Anlage kommt, da sie von der Verformung der Spreizschenkel und einem zusätzlichen Befestigungsmittel, zum Beispiel einer Schraube, angezogen wird.With regard to the structural design of the antenna arrangement is provided according to the invention, inter alia, that the fastening means are formed as an at least two approximately in V-shape aligned and extending from a counter-holder and fastened to the bottom plate expanding leg fastening claw. The two interconnected or connectable expansion legs are designed so that they can be performed on the one hand through an opening in the body part and on the other hand after performing a Vorverrastung (Pre-fixing) allow the antenna assembly. In this case, antenna arrangement means that structure which is to be arranged on or on the body part of the vehicle, in particular on its roof, and fixed in its position. The two expansion legs form in their connection region a kind of projection which allows the antenna arrangement to be prefixed to the body part in its position after the lower attachment area of the antenna arrangement has been passed through the opening in the body part. Subsequently, a further deformation of the two expansion legs to each other, so that the angle of the V-shape is reduced. This ensures that the bottom plate of the antenna assembly flat and durable on the surface of the body part comes to rest, since it is attracted by the deformation of the expansion limbs and an additional fastening means, for example a screw.

In Weiterbildung der Erfindung ist vorgesehen, dass die zwei Spreizschenkel ein Spreizschenkelpaar bilden und zumindest zwei Spreizschenkelpaare ausgehend von und an dem Gegenhalter angeordnet sind. Durch das Vorhandensein von mindestens zwei Spreizschenkelpaaren, deren einer Spreizschenkel an dem Gegenhalter befestigt und deren anderer Spreizschenkel an der Bodenplatte befestigt ist, werden zumindest zwei Befestigungspunkte in der Spitze der V-Form der Spreizschenkelpaare gebildet, der sich an der Unterseite des Karosserieteiles (zum Beispiel an der Unterseite des Fahrzeugdaches) zwecks Vorfixierung und Endfixierung abstützen kann. Sind mehr als zwei Spreizschenkelpaare, die sich gegenüberliegend angeordnet sind, vorhanden, liegen diese vorzugsweise symmetrisch auf einem Kreis in gleichem Abstand (Teilkreisabschnitten) zueinander.In a further development of the invention, it is provided that the two expansion legs form a pair of expansion legs and at least two expansion leg pairs are arranged starting from and on the counter-holder. Due to the presence of at least two spreader leg pairs, one spreader leg attached to the backstop and the other spreader leg attached to the bottom plate, at least two attachment points are formed in the apex of the V-shape of the spreader leg pair extending at the bottom of the body part (e.g. on the underside of the vehicle roof) for the purpose of prefixing and final fixation can support. If there are more than two expansion leg pairs, which are arranged opposite one another, they are preferably located symmetrically on a circle at the same distance (partial circle sections) from one another.

In Weiterbildung der Erfindung ist vorgesehen, dass das eine Ende des einen Spreizschenkels einen Befestigungsbereich aufweist, wodurch die Befestigungskralle mit der Bodenplatte verbunden ist. In diesem Befestigungsbereich ist das eine Ende des einen Spreizschenkels beispielsweise starr und dauerhaft mit der Bodenplatte verbunden. Das bedeutet, dass Bodenplatte und Spreizschenkel voneinander separate Teile sind, die durch einen geeigneten Befestigungsvorgang (zum Beispiel Verkleben, Verlöten, Verschweißen, Verschrauben, Vernieten oder dergleichen) starr miteinander verbunden sind. Alternativ dazu ist es denkbar, dass der eine Spreizschenkel über seinen Befestigungsbereich nicht starr, sondern bewegbar (flexibel) mit der Bodenplatte verbunden ist. Bevorzugt ist jedoch eine starre Anbindung der Befestigungskralle, genauer deren Enden deren Spreizkrallen, an der Bodenplatte vorzusehen, damit sich beim Verformen der Befestigungskralle die mittels des Gegenhalters auf die Befestigungskralle ausgeübten Kräfte an der Bodenplatte abstützen können, um die Antennenanordnung dauerhaft an dem Karosserieteil festlegen zu können.In a further development of the invention, it is provided that the one end of a spreader leg has a fastening region, whereby the fastening claw is connected to the bottom plate. In this attachment region, one end of a spreader limb is rigidly and permanently connected to the bottom plate, for example. This means that bottom plate and spreader legs are separate from each other, which are rigidly connected to each other by a suitable fastening operation (for example, gluing, soldering, welding, screwing, riveting or the like). Alternatively, it is conceivable that the one expansion leg is not rigidly connected via its fastening region, but is movable (flexibly) connected to the base plate. Preferably, however, a rigid connection of the fastening claw, more precisely their ends whose spreader claws, provided on the bottom plate, so that when deforming the fastening claw by the counter-holder forces exerted on the fastening claw forces can be supported on the bottom plate to set the antenna assembly permanently to the body part can.

In Weiterbildung der Erfindung ist die Befestigungskralle einteilig oder mehrteilig ausgebildet. Das bedeutet, dass der Gegenhalter sowie die beiden Spreizschenkel voneinander separate Bauteile sind, die einzeln hergestellt und anschließend zusammengebracht werden. In einem solchen Fall sind die beiden Spreizschenkel beispielsweise Teile, die in einem Stanzbiegeverfahren hergestellt werden. Der Gegenhalter ist beispielsweise ein Drehteil, da er einen runden Querschnitt mit Innengewinde aufweisen kann. Alternativ dazu können die beiden Spreizschenkel auch als einteiliges Bauteil, beispielsweise ebenfalls hergestellt in einem Stanzbiegeverfahren, ausgebildet sein. Im Regelfall werden die Spreizschenkel (unabhängig davon, ob sie einteilig oder mehrteilig sind) und der Gegenhalter voneinander separate Bauteile sein, da aufgrund ihrer Formgebung und Funktionsweise unterschiedliche Herstellungsmethoden (einerseits Stanzbiegeverfahren und andererseits Drehverfahren) zur Anwendung kommen.In a further development of the invention, the fastening claw is formed in one piece or in several parts. This means that the counter-holder and the two expansion legs are separate from each other, which are manufactured individually and then brought together. In such a case, for example, the two expansion limbs are parts which are produced in a stamping bending process. The counter-holder, for example, a rotating part, since it can have a round cross-section with internal thread. Alternatively, the two expansion limbs may also be formed as a one-piece component, for example also produced in a stamping bending process. As a rule, the expansion legs (regardless of whether they are one-piece or multi-part) and the counter-holder be separate from each other, since due to their shape and operation different production methods (On the one hand punching bending process and on the other hand turning process) are used.

Hinsichtlich des Verfahrens zum Betreiben der Antennenanordnung ist erfindungsgemäß unter Anderem vorgesehen, dass die Befestigungskralle durch eine Öffnung in einem Karosserieteil eines Fahrzeuges durchgeführt wird, wodurch es durch eine Anlage des einen Endes des Spreizschenkels an der Unterseite des Karosserieteiles zu einer Vorfixierung kommt, und anschließend der Gegenhalter betätigt wird, wodurch der Winkel zwischen den beiden Spreizschenkeln verkleinert wird und dadurch die Antennenanordnung dauerhaft an dem Karosserieteil festgelegt und in ihrer Lage fixiert wird.With regard to the method for operating the antenna arrangement is provided according to the invention, inter alia, that the fastening claw is performed through an opening in a body part of a vehicle, whereby it comes through an investment of one end of the expansion limb on the underside of the body part to a prefixing, and then the Counter-holder is actuated, whereby the angle between the two expansion limbs is reduced and thereby the antenna assembly is permanently fixed to the body part and fixed in position.

Dies hat den Vorteil, dass die Antennenanordnung in einem Arbeitsschritt von einer Person bei vereinfachter Konstruktion der Befestigungsmittel montiert werden kann. Nachdem die Vorfixierung stattgefunden hat, kann der Gegenhalter in geeigneter Weise betrieben werden, um die Antennenanordnung dauerhaft an dem Karosserieteil in seiner Lage festzulegen. Dies kann vorzugsweise dadurch erfolgen, dass in den Gegenhalter eine Befestigungsschraube eingeschraubt wird, wobei dieser Einschraubvorgang bewirkt, dass sich der Winkel zwischen den beiden Spreizschenkeln verkleinert und der Gegenhalter in Richtung der Bodenplatte angezogen wird.This has the advantage that the antenna arrangement can be mounted in one step by a person with a simplified design of the fastening means. After the prefixing has taken place, the anvil may be suitably operated to permanently secure the antenna assembly to the body panel in place. This can preferably take place in that a fastening screw is screwed into the counter holder, wherein this screwing causes the angle between the two expansion limbs is reduced and the counter-holder is tightened in the direction of the bottom plate.

Ein Ausführungsbeispiel zur Erläuterung des Aufbaus der erfindungsgemäßen Antennenanordnung und des Verfahrens zum Betreiben dieser Antennenanordnung ist im Folgenden anhand der Figuren 1 bis 3 beschrieben.An embodiment for explaining the structure of the antenna arrangement according to the invention and the method for operating this antenna arrangement is described below with reference to FIGS FIGS. 1 to 3 described.

Die Figur 1 zeigt, soweit im Einzelnen dargestellt, eine Antennenanordnung 1, die in diesem Ausführungsbeispiel als Dachantenne eines Fahrzeuges ausgeführt ist, aber nicht sein muss. Die in Figur 1 gezeigte Antennenanordnung 1 betrifft somit jedwede Antennenanordnung 1, die als separates System hergestellt und nach seiner Herstellung auf einem Karosserieteil eines Fahrzeuges angeordnet und dauerhaft befestigt wird. In dem Ausführungsbeispiel umfasst die Antennenanordnung 1 eine Abdeckung 2 (zum Beispiel aus Kunststoff), unter der nicht dargestellte Antennenelemente zum Empfangen und/oder Senden hochfrequenter Signale für Radio, Fernsehen, Telefon, Navigation und dergleichen angeordnet sind. Diese Antennenanordnung 1 wird auf einem Karosserieteil 3, das eine Öffnung 4 aufweist, angeordnet. Das Karosserieteil 3 kann, muss aber nicht ein Fahrzeugdach sein. Die Öffnung 4 in dem Karosserieteil ist hinsichtlich ihrer Form und Öffnungsfläche so gewählt, dass eine erfindungsgemäße Befestigungskralle 5 der Antennenanordnung 1 hindurchgeführt werden kann. Der Querschnitt ist beispielsweise rund oder quadratisch und hängt ab von der Ausgestaltung der Befestigungskralle 5.The FIG. 1 shows, as far as shown in detail, an antenna arrangement 1, which is designed in this embodiment as a roof antenna of a vehicle, but does not have to be. In the FIG. 1 shown antenna assembly 1 thus relates to any antenna assembly 1, which is manufactured as a separate system and arranged after its manufacture on a body part of a vehicle and permanently attached. In the exemplary embodiment, the antenna arrangement 1 comprises a cover 2 (for example made of plastic), under which antenna elements (not shown) for receiving and / or transmitting high-frequency signals for radio, television, telephone, navigation and the like are arranged. This antenna arrangement 1 is arranged on a body part 3, which has an opening 4. The body part 3 may, but need not be, a vehicle roof. The opening 4 in the body part is chosen with regard to their shape and opening area so that a fastening claw 5 of the antenna arrangement 1 according to the invention can be passed. The cross section is, for example, round or square and depends on the design of the fastening claw 5.

Die Befestigungskralle 5 umfasst einen Gegenhalter 6, von dem aus ein erster Spreizschenkel 7 ausgeht, wobei sich dem Spreizschenkel 7 ein weiterer Spreizschenkel 8 anschließt und diese beiden Spreizschenkel 7, 8 etwa in V-Form zueinander ausgerichtet sind. Diese Ausgestaltung der Befestigungskralle 5 ist in Figur 1, untere Darstellung, gezeigt. Nach der Herstellung einer solchen Befestigungskralle 5 wird diese an einer Bodenplatte 9 der Antennenanordnung 1 befestigt. Hierzu weist der Spreizschenkel 8 an seinem einen Ende einen Befestigungsbereich 10 auf. Dieser Befestigungsbereich 10 ist in dem konkreten Ausführungsbeispiel abgewinkelt und weist eine Öffnung auf, sodass zum Beispiel mittels einer Schraube oder eines Nietes dieser endseitig vorhandene Befestigungsbereich 10 an der Bodenplatte 9 festgelegt werden kann. In dem in den Figuren gezeigten Ausführungsbeispiel ist die Bodenplatte 9 der Antennenanordnung 1 so gestaltet, dass sie ebenfalls durch die Öffnung 4 des Karosserieteiles 3 nach unten hindurch ragt. Alternativ dazu kann jedoch auch die Bodenplatte 9 der Antennenanordnung 1 so gestaltet sein, dass sie mit der Oberfläche des Karosserieteiles 3 abschließt und somit nicht durch die Öffnung 4 hindurch ragt. In diesem Fall ist der Befestigungsbereich 10 des Spreizschenkels 8 so zu wählen, dass er ausreichend bis in den Bereich der Bodenplatte 9 hineinragt, um dort in geeigneter Weise befestigt werden zu können.The fastening claw 5 comprises a counter-holder 6, from which a first expansion limb 7 originates, wherein the expansion limb 7 is adjoined by a further expansion limb 8 and these two expansion limbs 7, 8 are aligned approximately in V-shape relative to one another. This embodiment of the fastening claw 5 is in FIG. 1 , lower illustration, shown. After the production of such a fastening claw 5, this is attached to a bottom plate 9 of the antenna assembly 1. For this purpose, the expansion limb 8 has at its one end a fastening region 10. This attachment region 10 is angled in the specific embodiment and has an opening, so that for example by means of a screw or a rivet this end attachment region 10 can be fixed to the bottom plate 9. In the embodiment shown in the figures, the bottom plate 9 of the antenna assembly 1 is designed so that it also protrudes through the opening 4 of the body part 3 down through. Alternatively, however, can Also, the bottom plate 9 of the antenna assembly 1 be designed so that it is flush with the surface of the body part 3 and thus does not protrude through the opening 4 passes. In this case, the attachment portion 10 of the expansion leg 8 is to be chosen so that it protrudes sufficiently into the region of the bottom plate 9 in order to be able to be fastened there in a suitable manner.

In Figur 2 ist gezeigt, dass die Antennenanordnung 1 vorbereitet ist und durch die Öffnung 4 in dem Karosserieteil 3 eingesetzt werden soll. Das bedeutet, dass ein Teil der Antennenanordnung 1 oberhalb des Karosserieteiles 3 verbleibt und lediglich die Befestigungsmittel, genauer die Befestigungskralle 5, bei Bewegung der Antennenanordnung 1 in der gezeigten Pfeilrichtung (von oben nach unten) durch die Öffnung 4 durchgeführt werden. Dieser abgeschlossene Vorgang, jedoch noch ohne weitere Betätigung der Befestigungskralle 5, ist in Figur 1 (obere Darstellung) dargestellt. Das bedeutet, dass hier die Befestigungskralle 5 (und in diesem Fall auch ein Teil der Bodenplatte 9) durch die Öffnung 4 in dem Karosserieteil 3 durchgeführt wurde, wodurch der flächig gestaltete Bereich der Bodenplatte 9 sowie der untere umlaufenden Rand der Abdeckung 2 (gegebenenfalls unter Zwischenlegung einer Dichtung) auf der Oberfläche des Karosserieteiles 3 zur Anlage gekommen ist.In FIG. 2 It is shown that the antenna assembly 1 is prepared and is to be inserted through the opening 4 in the body part 3. This means that part of the antenna arrangement 1 remains above the body part 3 and only the fastening means, more precisely the fastening claw 5, are moved through the opening 4 when the antenna arrangement 1 moves in the direction of the arrow (from top to bottom). This completed process, but still without further operation of the fastening claw 5, is in FIG. 1 (top illustration). This means that here the fastening claw 5 (and in this case also a part of the bottom plate 9) was performed through the opening 4 in the body part 3, whereby the area designed area of the bottom plate 9 and the lower peripheral edge of the cover 2 (optionally below The interposition of a seal) on the surface of the body part 3 has come to rest.

In Figur 3, untere Darstellung, ist zunächst die prinzipielle Wirkungsweise der Befestigungskralle 5 dargestellt, wenn der Gegenhalter 6 betätigt wurde. Durch den Gegenhalter 6 wird eine Befestigungsschraube 11 eingesetzt, deren nach oben weisender Endbereich in einem Gewinde in der Bodenplatte 9 eingreift. Dadurch kann sich der andere Endbereich der Befestigungsschraube 11 an oder in dem Gegenhalter 6 abstützen. Durch Betätigung der Befestigungsschraube wird einerseits der Winkel zwischen den beiden Spreizschenkeln 7, 8 (gegenüber dem Winkel, der in Figur 1 dargestellt ist) verkleinert, was zu Folge hat, dass der Übergangsbereich 12, in dem die beiden Spreizschenkel 7, 8 miteinander verbunden sind, sich nach außen (Pfeilrichtung) bewegt. Dadurch wird dieser Übergangsbereich 12 von unten gegen das Karosserieteil 3 gedrückt und kann sich dort abstützen, um die Antennenanordnung 1 dauerhaft an dem Karosserieteil 3 festzulegen. Wie in Figur 3 erkennbar, ist durch die Verbindung der beiden Spreizschenkel 7, 8 in dem Übergangsbereich 12 zueinander ein vorstehender Absatz gebildet, der bei Betätigung der Befestigungsschraube 11 auf der Unterseite des Karosserieteiles 3 bis zur endgültigen Lagefixierung entlang gleitet. Dies hat zum einen den Vorteil, dass durch diesen Vorgang Toleranzen (zum Beispiel Bauteiltoleranzen, Toleranzen in der Dicke des Karosserieteiles und dergleichen) ausgeglichen werden können. Außerdem können auch unterschiedliche Dicken von Karosserieteilen ausgeglichen werden. Dadurch erhöht sich die Flexibilität der erfindungsgemäßen Antennenanordnung 1. Außerdem hat dieser scharfkantige Bereich B den Vorteil, dass die Unterseite des Karosserieteiles 3 von Korrosionen und/oder Beschichtungen (zum Beispiel Farbe) befreit wird und eine elektrische Kontaktierung hergestellt wird. Diese elektrische Kontaktierung ist für die Masseanbindung der Antennenanordnung 1 hinsichtlich ihrer elektrischen Funktionalität erforderlich. In einem solchen Fall versteht es sich von selbst, dass das Karosserieteil 3 als auch zumindest der eine Endbereich des Spreizschenkels 7 sowie dieser Spreizschenkel 7 selbst und der Gegenhalter 6 aus einem elektrisch leitfähigen Material bestehen.In FIG. 3 , lower illustration, the principal mode of operation of the fastening claw 5 is initially shown when the counter-holder 6 has been actuated. By the counter-holder 6, a fastening screw 11 is used, the upwardly facing end portion engages in a thread in the bottom plate 9. As a result, the other end region of the fastening screw 11 can be supported on or in the counter holder 6. By operating the fastening screw, on the one hand, the angle between the two expansion legs 7, 8 (relative to the angle, the in FIG. 1 is shown reduced), which has the consequence that the transition region 12, in the the two expansion legs 7, 8 are connected to each other, moves outwards (arrow). As a result, this transition region 12 is pressed from below against the body part 3 and can be supported there in order to permanently fix the antenna arrangement 1 to the body part 3. As in FIG. 3 can be seen, is formed by the connection of the two expansion legs 7, 8 in the transition region 12 to each other a projecting shoulder which slides upon actuation of the fastening screw 11 on the underside of the body part 3 to the final positional fixation. This has the advantage that by this process tolerances (for example, component tolerances, tolerances in the thickness of the body part and the like) can be compensated. In addition, different thicknesses of body parts can be compensated. This also increases the flexibility of the antenna arrangement 1 according to the invention. In addition, this sharp-edged region B has the advantage that the underside of the body part 3 is freed from corrosion and / or coatings (for example paint) and an electrical contact is established. This electrical contact is required for the ground connection of the antenna assembly 1 in terms of their electrical functionality. In such a case, it goes without saying that the body part 3 and at least one end portion of the expansion leg 7 and this expansion leg 7 itself and the counter-holder 6 consist of an electrically conductive material.

In Figur 3, obere Darstellung, ist schließlich die endgültige Lage der Befestigungskralle 5 gezeigt, wenn der Montagevorgang sowie der Betätigungsvorgang der Befestigungsschraube 11 abgeschlossen ist. Dabei ist auch erkennbar, dass die Befestigungskralle 5 in ihrer axialen Ausrichtung (gegenüber Figur 1) verkleinert, das heißt zusammengedrückt wurde. Dadurch reduziert sich in vorteilhafter Weise die Bauhöhe der Befestigungskralle 5 in ihrem endmontierten Zustand.In FIG. 3 , Top illustration, finally, the final position of the fastening claw 5 is shown when the mounting operation and the operation of the fastening screw 11 is completed. It can also be seen that the fastening claw 5 in its axial alignment (opposite FIG. 1 ), that is compressed. This reduces the height of the mounting claw 5 in its final assembled state in an advantageous manner.

Die Befestigungskralle 5 weist einen Gegenhalter 6 auf, der hier einen runden Querschnitt aufweist und der dazu geeignet und ausgebildet ist, eine Befestigungsschraube (wird noch näher erläutert) aufzunehmen. Ausgehend von dem Gegenhalter 6 erstreckt sich ein erster Spreizschenkel 7, wobei an dem dem Gegenhalter 6 abgewandten Ende des Spreizschenkels 7 ein weiterer Spreizschenkel 8 angeordnet ist. In dem in Figur 1 gezeigten Ausführungsbeispiel bilden jeweils ein Spreizschenkel 7 und 8 ein Spreizschenkelpaar, sodass hier rechts und links von der Längsachse der Befestigungskralle 5 zwei Spreizschenkelpaare vorhanden sind. Es können, müssen aber nicht, wie in Figur 1 dargestellt ist, auch mehr als zwei Spreizschenkelpaare vorhanden sein. Bei dem in Figur 1 gezeigten Ausführungsbeispiel sind insgesamt vier Spreizschenkelpaare, ausgehend von dem Gegenhalter 6, vorhanden. Die vier Spreizschenkelpaare sind symmetrisch zueinander, das heißt jeweils gegenüberliegend, angeordnet, wobei jedoch auch mehr als vier Spreizschenkelpaare, allerdings auch nur drei Spreizschenkelpaare zu Anwendung kommen können. Das Vorhandensein von vier gegenüberliegend angeordneten Spreizschenkelpaaren ist dann von Vorteil, wenn die Öffnung 4 quadratisch ist. Ist die Öffnung 4 jedoch rund, bietet es sich an, lediglich zwei oder drei Spreizschenkelpaare einzusetzen. In dem Bereich A, in dem die Spreizschenkel 7, 8 miteinander verbunden sind, ist erkennbar, dass in diesem Fall die beiden Spreizschenkel 7, 8 einstückig ausgebildet sind und der Spreizschenkel 7 eine flächige Längserstreckung aufweist, genauso wie der Spreizschenkel 8. Darüber hinaus hat der Spreizschenkel 7 einen oder (wie in Figur 1 gezeigt) zwei abgewinkelte Flügel, die in dem Bereich A eine vorstehende Spitze bilden. Die effektive Größe der Spitze vergrößert sich bei Betätigung der Befestigungskralle 5, sodass dies im Bereich B in Figur 3 erkennbar ist. Damit wird in vorteilhafter Weise gewährleistet, dass sich der Endbereich des Spreizschenkels 7, genauer dessen beiden abstehenden Flügel, wirksam an der Unterseite des Karosserieteiles 3 abstützen können, wenn die Befestigungsschraube 11 endgültig in dem Gegenhalter 6 und der Bodenplatte 9 eingeschraubt wurde. Die beiden von dem Spreizschenkel 7 abstehenden Flügel sind mit 13 bezeichnet.The fastening claw 5 has a counter-holder 6, which here has a round cross section and which is suitable and designed to receive a fastening screw (will be explained in more detail). Starting from the counter-holder 6, a first expansion leg 7 extends, wherein at the end of the spreader leg 7 remote from the counter-holder 6, a further expansion leg 8 is arranged. In the in FIG. 1 shown embodiment, in each case a spreader leg 7 and 8 form a Spreizschenkelpaar, so here right and left of the longitudinal axis of the fastening claw 5 two Spreizschenkelpaare are present. It may, but does not have, as in FIG. 1 is shown, more than two Spreizschenkelpaare be present. At the in FIG. 1 shown embodiment, a total of four Spreizschenkelpaare, starting from the anvil 6, available. The four expansion leg pairs are symmetrical to each other, that is, in each case opposite, arranged, but also more than four Spreizschenkelpaare, but also only three Spreizschenkelpaare can be used. The presence of four oppositely arranged Spreizschenkelpaaren is advantageous if the opening 4 is square. However, if the opening 4 is round, it is advisable to use only two or three expansion leg pairs. In the region A, in which the expansion legs 7, 8 are connected to each other, it can be seen that in this case the two expansion legs 7, 8 are integrally formed and the expansion leg 7 has a flat longitudinal extent, as well as the expansion leg 8. In addition the expansion leg 7 a or (as in FIG. 1 shown) two angled wings, which form in the area A a projecting tip. The effective size of the tip increases upon actuation of the fastening claw 5, so that in the area B in FIG. 3 is recognizable. This ensures in an advantageous manner that the end region of the expansion limb 7, more precisely its two projecting wings, is effective on the underside of the body part 3 can support when the fastening screw 11 was finally screwed into the anvil 6 and the bottom plate 9. The two protruding from the expansion limb 7 wings are designated 13.
