Kabelift-xcrmgeeiement f*!r tiilsiskopartig ausfahrbare /»ntenneranastenCable lift system for telescopic antenna branches
Die Neuerung betrifft ein Kabelführungselement für teleskopartig ausfahrbare Antennenmasten, bestehend aus einem seitlich an dem Hast gehaltenen, da,«. Kabel umschließenden Ring.The innovation concerns a cable guide element for telescopically extendable antenna masts, consisting of a ring that is held on the side of the mast and encloses the cable.

Hierfür hat man Rollenanordnungen oder Führungsringe vorgesehen, durch die die Kabel beimThe cables (also called cables) to the antennas arranged at the top of the mast are held in guides along the mast. For this purpose, roller arrangements or guide rings have been provided through which the cables can be guided during Aus- und Einfahren des Mastes hindurchlaufen. Haben die Kabel durchgehend gleichen Querschnitt, können diese Führungen so ausgebildet sein, daß sie die Kabel mit geringem Spiel umgeben. Bei veränderlichem Querschnitt des Kabels, besonders wenn es aus mehrerenWhen the mast is extended and retracted, the guides can be designed so that they surround the cables with little play.

steht, müssen die Führung??, -er so ausgestaltet sein, daß die im Querschnitt größeren Kupplungen passieren können. Dadurch ergibt sich für die eigentlichen Kabel in den Führungen ein großes Spiel, das erhebliche Bewegungen des Kabels in den Führungen zuläßt. In der Betriebsstellung das Mastes werden die Kabel durch Windeinflüsse in den Führungen hin- und herbewegt, er zeugen starke Geräusche, und. ihre Außenisolierungen werden durch die dabei auftretenden Schläge beschädigt. Ähnliche Problerae treten im abgelegten Zustand des Mastes bei mobilen Antennenmasten beim Fahren infolge der Fahrerschütterungen auf. the guides must be designed in such a way that the couplings with a larger cross-section can pass through. This results in a large amount of play for the actual cables in the guides, which allows considerable movement of the cable in the guides. When the mast is in the operating position, the cables are moved back and forth in the guides by the wind , they generate loud noises, and their external insulation is damaged by the impacts that occur. Similar problems occur when the mast is put down with mobile antenna masts as a result of the driver's vibrations.
Der Neuerung liegt die Aufgabe zugrunde, diese Nachteile zu vermeiden und eine stets gute Führung derThe innovation is based on the task of avoiding these disadvantages and ensuring consistently good management of the Kabel in den Führungselementen zu erzielen. Dies wird dadurch erreicht, daß die als Ring ausgebildeten Führungselemente mit einer Platte aus elastischem Material versehen sind, die die Ringöffnung überdeckt und mit einer dem Kabelquerschnitt entsprechenden mittleCable in the guide elements. This is achieved by providing the guide elements, which are designed as a ring, with a plate made of elastic material that covers the ring opening and with a central ren öffnung versehen ist, von der strahlenförmig nach außen gerichtete Schlitze ausgehen.r opening from which slits radiate outwards.
Bei elektrotechnischen Geräten ist es zwar bekannt, Durchtrittsöffnungen für Kabel in Gerätegehäusen mit geschlitzten Platten aus elastischem Material zu ver schließen (DE-PS 38 32 229). Dies« dienen jedoch der Abdichtung des Gehäuses gegen Eintritt von Feuchtigkeit, wozu bei Führungselemente!! an Teleskopmasten keine Veranlassung besteht. In the case of electrical equipment, it is known to close openings for cables in device housings with slotted plates made of elastic material (DE-PS 38 32 229). However, this serves to seal the housing against the ingress of moisture, which is not necessary in the case of guide elements on telescopic masts.
Eine vorteilhafte Ausgestaltung des Kabel führungselemente ergibt sich, wenn der Ring aus zwei ringförmigen Teilen besteht, zwischen denen die elastische Platte eingespannt ist. Zweckmäßigerveie« gehen die Schlitze der elastischen Platte außen in Löcher über, die vor dem Schlitzen hergestellt sind. Damit wird ein Einreißen der Platte vermieden.An advantageous design of the cable guide element is achieved when the ring consists of two ring-shaped parts between which the elastic plate is clamped. The slots in the elastic plate conveniently merge into holes on the outside that are made before the slots are cut. This prevents the plate from tearing.
In der Zeichnung sind mehrere Ausführungsformen der Erfindung dargestellt, und zwar zeigen Fig. 1, 2 und Draufsichten auf die Führungselemente und Fig. 4 einen Schnitt nach der Linie IV-IV in Fig. 2.Several embodiments of the invention are shown in the drawing, namely Fig. 1, 2 and top views of the guide elements and Fig. 4 shows a section along the line IV-IV in Fig. 2.
Jedes Führungselement besteht aus einem zweiteiligen Ring 1, 2, dessen einer Teil 1 einen Haltearm 3 aufweist, mit dem der Ring an einem Teil des Teleskopinastes befestigbar ist. Zwischen den beiden Ringteilen 1 und 2 ist eine Platte 4 aus elastischem Material, wie Gummi, mittels Schrauben 5 eingespannt, die die beiden Ringteile miteinander verbinden.Each guide element consists of a two-part ring 1, 2, one part 1 of which has a holding arm 3, with which the ring can be attached to a part of the telescopic branch. A plate 4 made of elastic material, such as rubber, is clamped between the two ring parts 1 and 2 by means of screws 5, which connect the two ring parts to one another.
Die Platte 4 weist in der Mitte eine Öffnung 6 auf, die im wesentlichen dem Querschnitt des durch den Ring zu führenden, nicht dargestellten Kabels entspricht. Von ihr gehen strahlenförmig nach außen gerichtete Schlitze 7 aus, die die Platte 4 in einzelne Lappen unterteilen, die beim Durchtritt von im Querschnitt größeren Kupplungsteilen des Kabels ausschwenken. Die Schlitze gehen außen in Löcher 9 über, wodurch das Ausschwenken der Lappen erleichtert wird.The plate 4 has an opening 6 in the middle, which essentially corresponds to the cross-section of the cable (not shown) to be guided through the ring. Slots 7 radiate outwards from it, dividing the plate 4 into individual tabs, which swing out when coupling parts of the cable with a larger cross-section pass through. The slots merge into holes 9 on the outside, which makes it easier to swing out the tabs.
