Eine derartige Vorrichtung ist aus der EP 0 372 265 B1 bekannt. Bei dieser Vorrichtung ist eine Antennenvorrichtung vorgesehen, die in einem relativ niedrigen Turm bekannten Aufbaues angeordnet und in mehreren Stufen in der Höhe ausfahrbar ist, um den Antennenstab in Betriebsstellung zu bringen. Zu diesem Zweck umfaßt die Antennenvorrichtung als erste Ausfahrstufe einen hohlen Mast, der mittels eines in dem Turm vorgesehenen Antriebszylinders mit einer Kolbenstange ausfahrbar und einfahrbar betätigt wird. Des Weiteren ist in dem Mast eine teleskopisch ausgebildete Kolben-Zylinder-Einrichtung vorgesehen, die aus einem ersten und einem zweiten Zylinder besteht, wobei der zweite Zylinder an der Oberseite des Kolbens des ersten Zylinders befestigt ist. Der zweite Zylinder weist einen an seiner Oberseite den Antennenstab und an seiner Unterseite ein biegsames Einziehglied tragenden Kolben auf, wobei das Einziehglied über ein frei drehbares Umlenkrad geführt ist, das oberseitig an dem Kolben des ersten Zylinders befestigt ist. Der zweite Zylinder weist elektrische Eigenschaften auf, die denen des Antennenstabes entsprechen, so dass sich mit diesem eine gesamte strahlende Antennenlänge ergibt, die sich aus der Länge des Antennenstabes und aus der Länge des ausgefahrenen Abschnitts des zweiten Zylinders zusammensetzt. Letzterer ist elektrisch leitend und steht mit dem Antennenstab in elektrischem Kontakt. An der Austrittsstelle des hohlen Mastes für den zweiten Zylinder ist ein diesen Zylinder außen umgebendes Isolierringteil ortsfest angeordnet, welches als weitere Signalübertragungsstelle dient und an externe elektrische Signalleitungen angeschlossen ist, über welche Signale in das U-Boot und aus dem U-Boot geleitet werden.Such a device is known from EP 0 372 265 B1. With this device an antenna device is provided which is relatively low Tower of known structure arranged and extendable in several stages in height is to bring the antenna rod into operating position. To this end the antenna device comprises a hollow mast as the first extension stage by means of a drive cylinder with a piston rod provided in the tower extendable and retractable. Furthermore, there is a telescopic in the mast trained piston-cylinder device provided, which consists of a first and a second cylinder, the second cylinder at the top the piston of the first cylinder is attached. The second cylinder instructs you the top of the antenna rod and on the bottom a flexible retractable member bearing piston, the pull-in member via a freely rotatable deflection wheel is guided, which is attached to the top of the piston of the first cylinder. The second cylinder has electrical properties that those of the antenna rod correspond, so that with this an entire radiating antenna length results from the length of the antenna rod and the length of the extended Section of the second cylinder is composed. The latter is electric conductive and in electrical contact with the antenna rod. At the exit point the hollow mast for the second cylinder is one of these cylinders outside surrounding insulating ring part arranged stationary, which as a further signal transmission point serves and is connected to external electrical signal lines, which signals are routed into and out of the submarine.

Diese bekannte Antennenvorrichtung weist Nachteile auf, die die Zuverlässigkeit der Signalübertragung beeinträchtigen und den Einsatzbereich der Vorrichtung beschränken. So bewirkt die Übertragung des Signals über die erste Gleitverbindung, nämlich derjenigen zwischen dem den Antennenstab tragenden Kolben und dem diesen führenden zweiten Zylinder, und der zweiten Gleitverbindungsstelle zweiter Zylinder/Isolierringteil, dass gute Empfangs- bzw. Sendebereitschaft nur bei vollständig ausgefahrener Teleskopantenne besteht, d.h. nur bei relativem Stillstand der die besagten Gleitverbindungen bildenden Elemente, weil diese Gleitverbindungen insbesondere dem Seewasser ausgesetzt sind, wodurch die Signalübertragung unsicher und gestört sein kann bis hin zur Unterbrechung des zu übertragenden Signals. Dieser Effekt wird noch dadurch begünstigt, dass die Gleitverbindungen den Biegebelastungen des ausgefahrenen Mastes ausgesetzt sind und dass an diesen Stellen Abbrand durch Funkenerosion auftreten kann, was die Signalleitfähigkeit der Gleitverbindungen weiter herabsetzt.This known antenna device has disadvantages in terms of reliability affect signal transmission and the area of application of the device restrict. The transmission of the signal via the first sliding connection namely that between the piston carrying the antenna rod and the leading second cylinder, and the second sliding joint second cylinder / insulating ring part, that good reception or transmission readiness only when the telescopic antenna is fully extended, i.e. only with relative The elements forming the said sliding connections come to a standstill because these Sliding connections are particularly exposed to sea water, which causes the Signal transmission can be unsafe and disturbed up to the interruption of the transmitting signal. This effect is further favored by the fact that Sliding connections exposed to the bending loads of the extended mast and that spark erosion can occur at these points, which further reduces the signal conductivity of the sliding connections.

Die Aufgabe der Erfindung besteht in der Schaffung einer ausfahrbaren, insbesondere als Antenne dienenden Vorrichtung, deren Signalübertragungseigenschaften sowohl während ihres Einfahrens als auch während ihres Ausfahrens sowie in jeder beliebigen Ausfahrhöhe einschließlich deren Endpositionen dauerhaft erhalten bleibt.The object of the invention is to provide an extendable, in particular device serving as an antenna, its signal transmission properties both during their retraction and during their retraction and permanently at any extension height including their end positions preserved.

Ausgehend von der Informationsvorrichtung der eingangs erwähnten Art wird diese Aufgabe erfindungsgemäß dadurch gelöst, dass das Einziehglied zum Leiten elektrischer Signale ausgebildet ist und sowohl mit dem Antennenstab als auch mit der externen, in das Innere des U-Bootes führenden Signalleitung in fester elektrischer Verbindung steht und dass der erste Zylinder aus einem formstabilen Kunststoffmaterial.Starting from the information device of the type mentioned at the beginning solved this task according to the invention in that the pull-in member for guiding electrical signals is formed and both with the antenna rod and with the external signal line leading into the interior of the submarine in fixed electrical Connection is established and that the first cylinder made of a dimensionally stable plastic material.

Durch diese Lösung ist eine einfach aufgebaute, ausfahrbare und bevorzugt als Antenne dienende Vorrichtung geschaffen, die sich neben ihrer Eignung für niedrige U-Boottürme dadurch auszeichnet, dass dank der Ausbildung des Einziehgliedes auch als innere elektrische Signalleitung zwischen dem Antennenstab und der externen Signalleitung dauerhaft eine störungsfreie Signalübertragung erfolgt und dass dadurch, dass das Einziehglied auch selbst als Antenne wirkt und durch den ersten Zylinder aus Kunststoff nicht gestört wird, die hohe Antennenleistung der Antennenvorrichtung in ihrem ausgefahrenen Zustand im Vergleich zum Stand der Technik erhalten bleibt. Da auch kein Abbrand an den Gleitverbindungsstellen des Mastes durch Funkenerosion mehr auftreten kann, ist auch der Gleitverschleiß an den Gleitverbindungsstellen herabgesetzt und damit die Lebensdauer des Mastes erhöht.This solution is a simple, extendable and preferred as Antenna serving device created, which is in addition to its suitability for Low submarine towers are characterized by the fact that thanks to the design of the retractable link also as an internal electrical signal line between the antenna rod and the external signal line is permanently free of interference and that by the fact that the pull-in member itself acts as an antenna and through the first plastic cylinder is not disturbed, the high antenna performance the antenna device in its extended state compared to the state the technology is preserved. Since there is no burn-up at the sliding connection points of the mast due to spark erosion is also the sliding wear reduced at the sliding joints and thus the life of the Mastes increased.

Gemäß einer zweckmäßigen Ausführung der Erfindung kann das Einziehglied selbst elektrisch leitend sein oder das Einziehglied einen gesonderten Signalleiter aufweisen. Nach einer weiteren vorteilhaften Ausführung der Erfindung kann das Einziehglied zwecks zentraler Ausrichtung in dem ersten Zylinder mit einer Vielzahl von Zentrierelementen versehen sein, wobei diese aus Kugeln oder Scheiben bestehen können, die an dem biegsamen Einziehglied vorgesehen sind Im Falle der Verwendung von Kugeln können diese aneinanderstoßend und im Falle der Verwendung von Scheiben können diese voneinander beabstandet angeordnet sein. Nach einer anderen vorteilhaften Ausführung der Erfindung kann der zweite Zylinder ein inneres, feststehendes, von außen gespeistes und den Kolben dieses Zylinders auf seinem gesamten Hubweg gleitend und abgedichtet durchdringendes Zuführungsrohr für das diesen Kolben auf seiner Oberseite beaufschlagende Druckfluid aufweisen.According to an expedient embodiment of the invention, the pull-in member itself be electrically conductive or the pull-in member has a separate signal conductor exhibit.

Wie aus den Figuren hervorgeht, ist das U-Boot nur teilweise angedeutet dargestellt und allgemein mit 1 bezeichnet. Es ist mit einem relativ niedrigen Turm 2 bekannten Aufbaus ausgestattet, in dem unter anderem eine allgemein mit 3 bezeichnete Antennenvorrichtung als Informationsvorrichtung angeordnet ist.As can be seen from the figures, the submarine is only partially indicated and generally designated 1. It is with a relatively low tower 2 known structure equipped in which, among other things, a generally with 3 designated antenna device is arranged as an information device.

Die Antennenvorrichtung 3 weist, wie aus den Figuren zu ersehen ist, eine teleskopisch ausgebildete Kolben-Zylinder-Einrichtung 5 auf, die innerhalb des Turmes 2 an der Decke 4 desselben befestigt ist. Sie besteht aus einem ersten, inneren, oben und unten offenen Zylinder 6 und aus einem zweiten, äußeren Zylinder 7, wobei der erste Zylinder 6 an der Oberseite des Kolbens 8 des zweiten Zylinders 7 starr befestigt ist und aus einem formstabilen Kunststoffmaterial, bspw. einem Faserverbundmaterial, besteht. Der zweite Zylinder 7 erstreckt sich vorzugsweise über die gesamte Höhe des Turmes 2. Die beiden Zylinder 6 und 7 sind über Druckfluidleitungen 9 und 10 mit einem schematisch angedeutet dargestellten, vorzugsweise als Hydraulik 11 ausgebildeten Antrieb verbunden, wobei die Druckfluidleitung 9 mit dem Rückraum des Zylinders 7 über ein inneres, feststehendes und den Kolben 8 dieses Zylinders auf seinem gesamten Hubweg gleitend und abgedichtet durchdringendes Zuführungsrohr 7a in Verbindung steht.The antenna device 3 has, as can be seen from the figures, a telescopic one trained piston-cylinder device 5 on the inside of the tower 2 is attached to the ceiling 4 of the same. It consists of a first, inner, cylinder 6 open at the top and bottom and from a second, outer cylinder 7, the first cylinder 6 on the top of the piston 8 of the second cylinder 7 is rigidly attached and made of a dimensionally stable plastic material, for example Fiber composite material. The second cylinder 7 preferably extends over the entire height of the tower 2. The two cylinders 6 and 7 are over Pressure fluid lines 9 and 10 with a schematically indicated, preferably connected as a hydraulic drive 11, the pressure fluid line 9 with the rear space of the cylinder 7 via an internal, fixed and the piston 8 of this cylinder sliding over its entire stroke and sealed penetrating feed pipe 7a is connected.

Der erste Zylinder 6 weist einen Kolben 12 auf, an dessen Oberseite ein Antennenstab 13 und an dessen Unterseite ein biegsames Einziehglied 14, z.B. ein Seil oder eine Kette, befestigt ist, das aus einem elektrisch leitenden Material besteht und den Zylinder 7 axial durchläuft. Anderenends ist das Einziehglied 14 an der oberen Innenseite des Zylinders 7 befestigt und dort elektrisch isoliert aus dem Zylinder 7 herausgeführt, wo es in eine externe Signalleitung 17 übergeht, die das Einziehglied 14 mit einem in dem U-Boot oder im Ausfahrmast untergebrachten Antennenanpaßgerät 18 verbindet. Alternativ kann die Signalleitung 17 auch innerhalb des Zylinders 7 in einem Rohr (nicht gezeigt) geführt und durch den Zylinderboden herausgeführt sein, und zwar in sinngemäßer Anwendung wie beim Zuführungsrohr 7a, um dann mit dem Antennenanpassgerät 18 verbunden zu sein.The first cylinder 6 has a piston 12, on the top of which an antenna rod 13 and on the underside thereof a flexible retractable member 14, e.g. a rope or a chain is attached, which consists of an electrically conductive material and passes through the cylinder 7 axially. At the other end, the pull-in member 14 is on the attached upper inside of the cylinder 7 and there electrically isolated from the Cylinder 7 led out, where it merges into an external signal line 17, which Retraction member 14 housed in the submarine or in the mast Antenna adapter 18 connects. Alternatively, the signal line 17 can also inside the cylinder 7 in a tube (not shown) and through the Be led out cylinder bottom, and in the same application as in Feed pipe 7a, to then be connected to the antenna matching device 18.

Das Einziehglied 14, das aus dem unten offenen Zylinder 6 austritt, läuft über ein frei drehbares Umlenkrad 15, das oberseitig an dem Kolben 8 des zweiten Zylinders 7 befestigt ist. Dadurch wird der Antennenstab 13 eingezogen, wenn der Kolben 8 nach unten verfährt. Das Umlenkrad befindet sich des Weiteren in einer unteren Ausnehmung 16 des Zylinders 6; kann sich aber auch in einer Ausbuchtung des Kolbens 8 befinden, um den maximalen Hub für diesen Kolben und damit auch für den zweiten Zylinder 7 ausnutzen zu können.The pull-in member 14, which emerges from the cylinder 6, which is open at the bottom, runs in via freely rotatable deflection wheel 15, the top of the piston 8 of the second cylinder 7 is attached. As a result, the antenna rod 13 is retracted when the Piston 8 moves down. The deflection wheel is also in a lower recess 16 of the cylinder 6; can also be in a bulge of the piston 8 are to the maximum stroke for this piston and thus can also be used for the second cylinder 7.

Zwecks zentraler Ausrichtung des Einziehgliedes 14 in dem Zylinder 6 ist dieses mit einer Vielzahl von Zentrierelementen 19 versehen, die kugelförmig oder scheibenförmig ausgebildet sind, wobei bei scheibenförmiger Ausbildung eine gegenseitige Distanz zwischen den Scheiben belassen ist, während die Zentrierelemente 19 bei kugelförmiger Ausbildung vorteilhaft aneinanderstoßend angeordnet sind.For the purpose of central alignment of the pull-in member 14 in the cylinder 6, this is provided with a plurality of centering elements 19 which are spherical or are disc-shaped, with a disc-shaped configuration mutual distance between the disks is left while the centering elements 19 advantageously arranged abutting in a spherical configuration are.

Aufgrund des signalleitenden Einziehgliedes ist der Antennenstab 13 in jeder Ausfahrhöhe der Antennenvorrichtung 3 signaltechnisch sicher mit dem Antennenanpassgerät 18 verbunden, wodurch es möglich ist, die Antennenvorrichtung in jeder Ausfahrhöhe zum Senden und Empfangen zu benutzen. Dabei ergibt sich eine strahlende Antennenlänge, die sich aus der Länge des Antennenstabes 13 und jeweils desjenigen Längenteils des elektrisch leitenden Einziehgliedes 14, der sich zwischen dem Kolben 12 des Zylinders 6 aus Kunststoff und dem jeweils aus dem Zylinder 7 ausgefahrenen Abschnitt des Zylinders 6 erstreckt, zusammensetzt.Due to the signal-conducting pull-in member, the antenna rod 13 is in each Extending height of the antenna device 3 is signal-safe with the antenna adapter 18, whereby it is possible to mount the antenna device in any exit height for sending and receiving. It follows a radiating antenna length, which results from the length of the antenna rod 13 and each of the longitudinal part of the electrically conductive pull-in member 14 which between the piston 12 of the cylinder 6 made of plastic and each of the Cylinder 7 extends portion of the cylinder 6 extends.

Zur Aktivierung der Antennenvorrichtung 3 werden die Zylinder 6 und 7 aus der zentralen U-Boot-Hydraulik oder einer speziellen Hydraulik 11 mit Druckfluid beaufschlagt. Dies erfolgt über die Druckfluidleitungen 9 und 10, so dass beide Kolben 8 und 12 von unten mit Druckfluid beaufschlagt werden, und zwar der Kolben 12 deshalb, weil der Zylinder 6 unten offen ist und im dargestellten Fall über die Ausnehmung 16 mit der Oberseite des Kolbens 8 kommuniziert. Die Druckverhältnisse sind dabei so aufeinander abgestimmt, dass eine Aufwärtsbewegung der beiden Kolben 8 und 12 gewährleistet ist. Zum Einfahren der Antennenvorrichtung 3 wird die Druckfluidleitung 10 drucklos geschaltet, während die Druckfluidleitung 9 und damit der Raum oberhalb des Kolbens 8 mit einem Druck beaufschlagt bleibt, der eine Kraft erzeugt, die den Kolben 8 abwärts bewegt und den Kolben 12 mittels des Einziehgliedes 14 nach unten zieht. Im gezeigten Fall bewirkt die Bauweise der beschriebenen Antennenvorrichtung, dass der Antennenstab 13 aufgrund des Einziehgliedes 14 im wesentlichen den doppelten Hubweg ausführt als der Kolben 8 des Zylinders 7 .To activate the antenna device 3, the cylinders 6 and 7 are removed from the central submarine hydraulics or a special hydraulic 11 with pressurized fluid acted upon. This is done via the pressure fluid lines 9 and 10, so that both Pistons 8 and 12 are pressurized with pressure fluid from below, namely Piston 12 because the cylinder 6 is open at the bottom and in the case shown Communicates with the top of the piston 8 via the recess 16. The Pressure conditions are coordinated so that an upward movement the two pistons 8 and 12 is guaranteed. To retract the Antenna device 3, the pressure fluid line 10 is depressurized while the pressure fluid line 9 and thus the space above the piston 8 with a Pressure remains applied, which generates a force that moves the piston 8 downward and pulls the piston 12 down by means of the pull-in member 14. In the shown Fall causes the construction of the antenna device described that the Antenna rod 13 due to the retraction member 14 essentially double Stroke runs as the piston 8 of the cylinder 7.

Im Sinne der Erzielung einer hohen Effizienz der Antennenvorrichtung 3 ist es wünschenswert, deren Antennenteil möglichst weit ausfahren zu können. Dies kann, wie in Fig.3 gezeigt, mittels eines Antriebszylinders 20 erreicht werden, der in dem oder im Wesentlichen in dem Turm 2 vorgesehen ist und eine ausfahrbare und einfahrbare Kolbenstange 21 aufweist, die im Bereich des oberen Endes des Zylinders 7 angreift. Der Antriebszylinder 20 hat eine Gesamtlänge, die der des Zylinders 7 im wesentlichen entspricht und ist mit seinem unteren Ende am Fuß des Turmes 2 befestigt, wo sich auch die Zuleitungsanschlüsse 22 und 23 für die Betätigung und Versorgung des Antriebszylinders 20 befinden. Bei diesem Aufbau sind der Zylinder 7 und der Antriebszylinder 20, letzterer in eingefahrenem Zustand, in einem oben geschlossenen hohlzylinderförmigen Mast 24 untergebracht. Dabei ragt der Zylinder 6 aus der Oberwand des Mastes 24 heraus, und der Mast selbst ist in dem Deckel 4 des Turmes 2 kolbenstangenartig geführt und gleitend abgedichtet. Mit dieser Ausführung ist es möglich, die Antennenvorrichtung 3 um die Hublänge des Antriebszylinders 20 weiter aus dem Turm 2 des U-Bootes 1 auszufahren.It is in the sense of achieving a high efficiency of the antenna device 3 desirable to be able to extend the antenna part as far as possible. This can, as shown in Figure 3, be achieved by means of a drive cylinder 20 which is provided in or essentially in the tower 2 and an extendable and retractable piston rod 21 which in the region of the upper end of the Cylinder 7 attacks. The drive cylinder 20 has an overall length that the Cylinder 7 essentially corresponds and is at its lower end at the foot attached to the tower 2, where there are also the supply connections 22 and 23 for the Actuation and supply of the drive cylinder 20 are. With this setup are the cylinder 7 and the drive cylinder 20, the latter in the retracted state, housed in a hollow cylindrical mast 24 closed at the top. The cylinder 6 protrudes from the top wall of the mast 24, and the mast itself is guided and sliding in the cover 4 of the tower 2 like a piston rod sealed. With this embodiment, it is possible to move the antenna device 3 around the stroke length of the drive cylinder 20 further from the tower 2 of the submarine 1 to extend.

Anstelle des Antennenstabes 13 können auch andere Informationsübermittler oder Funktionsgeräte verwendet werden. In diesem Falle ist der Antennenstab 13 ein länglicher, vorzugsweise starrer Träger, z.B. ein Rohrteil, an dessen oberen Ende eine Radareinrichtung oder eine andere Informationseinrichtungen montiert ist bzw. sind, die einzeln oder in Kombination miteinander vorhanden sein können. Die Versorgung dieser Einrichtungen mit elektrischer Energie erfolgt dann ebenfalls über das biegsame Einziehglied 14.Instead of the antenna rod 13, other information transmitters or Functional devices are used. In this case the antenna rod 13 is on elongated, preferably rigid, e.g. a pipe part, at its upper end a radar device or another information device is mounted or are, which can be present individually or in combination with one another. These devices are then also supplied with electrical energy via the flexible retractable member 14.
