Description

Ausgangspunkt der Erfindung ist eine Vorrichtung zum Halten einer Parabolantenne mit den im Oberbegriff des Anspruchs 1 angegebenen Merkmalen. Es ist bekannt, an der Rückseite der Parabolantenne zwei parallele, lotrechte Wangen zu befestigen und diese schwenkbar mit einem weiteren Paar paralleler Wangen zu verbinden, die Teil einer Halterung sind, die zur Befestigung an einem Ständer oder Antennenmast für die Parabolantenne vorgesehen ist. Bei der bekannten Vorrichtung sind die Wangen der Parabolantenne mit jenen der Halterung durch einen waagerechten Schraubbolzen miteinander verbunden. Dieser Schraubbolzen ist in der Nähe des oberen Randes der Wangen vorgesehen. Um die Parabolantenne wählbarer Neigung fixieren zu können, sind in dem einen Wangenpaar unterhalb der Schwenkachse zwei Langlöcher vorgesehen, welche kreisbogenförmig ausgebildet sind und ihren Krümmungsmittelpunkt auf der Schwenkachse haben. Durch diese Langlöcher erstrecken sich zwei Klemmschrauben hindurch in Gewindebohrungen der beiden anderen Wangen. Durch Festziehen dieser Klemmschrauben kann die Parabolantenne in vorwählbarer Neigung an den Wangen der Halterung festgelegt werden.The starting point of the invention is a device for holding a parabolic antenna with the features specified in the preamble of claim 1. It is known to attach two parallel, vertical cheeks to the rear of the parabolic antenna and to pivotally connect them to another pair of parallel cheeks, which are part of a holder which is provided for fastening to a stand or antenna mast for the parabolic antenna. In the known device, the cheeks of the parabolic antenna are connected to each other by a horizontal screw bolt. This bolt is provided near the top of the cheeks. In order to be able to fix the parabolic antenna of selectable inclination, two elongated holes are provided in one pair of cheeks below the swivel axis, which are designed in the shape of a circular arc and have their center of curvature on the swivel axis. Two clamping screws extend through these elongated holes in threaded holes in the other two cheeks. By tightening these clamping screws, the parabolic antenna can be fixed on the cheeks of the bracket with a pre-selectable inclination.

Die bekannte Vorrichtung hat den Nachteil, dass die Parabolantenne nicht leicht am Ständer montiert werden kann. Die Verbindung zwischen der Parabolantenne und ihrer Halterung ist nämlich so schwierig, dass sie zwar zu ebener Erde, aber kaum auf einem Antennenmast oder auf einem geneigten Dach durchgeführt werden kann. Vielmehr ist es an solchen Aufstellorten nötig, die Parabolantenne zunächst am Erdboden mit ihrer Halterung zu versehen und dann diese Halterung samt der daran befestigten Parabolantenne an dem dafür vorgesehenen Ständer -in der Regel ist das ein Standrohr - zu befestigen; aber auch letzteres ist angesichts der Größe und des Gewichtes der Parabolantenne noch ausserordentlich mühsam.The known device has the disadvantage that the parabolic antenna cannot be easily mounted on the stand. The connection between the dish and their mounting is so difficult that it can be carried out on the ground, but hardly on an antenna mast or on a sloping roof. Rather, in such locations it is necessary to provide the parabolic antenna with its holder on the ground first and then to fix this holder together with the attached parabolic antenna to the stand provided for this purpose - as a rule this is a standpipe; but the latter is also extremely laborious given the size and weight of the parabolic antenna.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Halten einer Parabolantenne so zu verbessern und so zu vereinfachen, dass man auch an Aufstellorten auf einem geneigten Dach oder auf einem Antennenmast zunächst eine Halterung an einem Antennenständer befestigen und dann ohne große Mühe die Parabolantenne in dieser Halterung einsetzen kann.The invention has for its object to improve and simplify a device for holding a parabolic antenna in such a way that even at locations on a sloping roof or on an antenna mast first attach a bracket to an antenna stand and then without much effort the parabolic antenna in it Bracket can use.

Diese Aufgabe wird gelöst durch eine Vorrichtung mit den im Anspruch 1 angegebenen Merkmalen. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.This object is achieved by a device with the features specified in claim 1. Advantageous developments of the invention are the subject of the dependent claims.

Dadurch, dass die Schwenkachse der Parabolantenne nicht mehr durch einen Schraubbolzen, sondern durch zwei fest an den Wangen der Parabolantenne angebrachte Zapfen gebildet wird, welche in zwei dazu passende, in den Wangen der Halterung geneigt verlaufende Schlitze eingesenkt werden, kann die Parabolantenne bei ihrer Montage zunächst ohne Rücksicht auf die Justierung ihrer Neigung in die zuvor am Ständer der Antenne befestigte Halterung, die die Wangen mit den beiden geneigt verlaufenden Schlitzen umfasst, eingehängt werden. Diese ist mit einer Hand möglich, und danach hängt die Parabolantenne unverlierbar in den schrägen Schlitzen der Halterung. So gesichert, kann anschließend die Neigung der Parabolantenne justiert und durch die vorgesehenen Klemmschrauben fixiert werden. Dabei sind die Anordnungen aus Klemmschraube, Langloch und Gewindebohrung sowohl oberhalb als auch unterhalb der durch die Zapfen gebildeten Schwenkachse vorgesehen. Das hat den Vorteil, daß das auf die Parabolantenne wirkende Kippmoment genau so gut aufgefangen werden kann wie bei der eingangs beschriebenen bekannten Vorrichtung, denn sowohl bei der bekannten Vorrichtung als auch bei der neuen Vorrichtung befinden sich Klemmschrauben in der Nähe des oberen und des unteren Randes der lotrechten Wangen. Da jedoch bei der neuartigen Vorrichtung die Schwenkachse nicht mehr durch einen am oberen Rand der Wangen vorgesehenen Schraubbolzen gebildet wird, sondern in der Mitte zwischen den oberen und unteren Schraubbolzen angeordnet ist, hat man bei der neuen Vorrichtung bei gleich gebliebener Höhe der Wangen und gleich gebliebenener Bogenlänge der Langlöcher einen doppelt so großen Ver stellwinkel für die Neigung der Parabolantenne als bei der bekannten Vorrichtung. Darin liegt ein weiterer Vorteil der neuen Vorrichtung.Because the swivel axis of the parabolic antenna is no longer attached to the cheeks of the parabolic antenna by one bolt, but by two Cone is formed, which are sunk into two matching slots, which run inclined in the cheeks of the bracket, the parabolic antenna can be initially installed without regard to the adjustment of its inclination in the bracket previously attached to the stand of the antenna, which the cheeks with the includes two sloping slots. This is possible with one hand, and then the parabolic antenna hangs captively in the oblique slots of the holder. Secured in this way, the inclination of the parabolic antenna can then be adjusted and fixed using the clamping screws provided. The arrangements of clamping screw, slot and threaded hole are provided both above and below the pivot axis formed by the pin. This has the advantage that the tilting moment acting on the parabolic antenna can be absorbed just as well as in the known device described at the outset, because both the known device and the new device have clamping screws near the upper and lower edges the vertical cheeks. However, since in the novel device the pivot axis is no longer formed by a screw bolt provided on the upper edge of the cheeks, but is arranged in the middle between the upper and lower screw bolts, the new device has the same height of the cheeks and the same Arc length of the elongated holes a twice as large ver Setting angle for the inclination of the parabolic antenna than in the known device. This is another advantage of the new device.

Zur Justierung der Neigung der Parabolantenne befindet sich an der Halterung vorzugsweise ein Teil mit einer Gewindebohrung, in welche eine mit Aussengewinde versehene Stange eingedreht ist, welche mit ihrer Spitze gegen die Rückseite der Parabolantenne stößt. Damit die Lage der Spitze an der Rückseite der Parabolantenne eindeutig definiert ist, ist dort eine Mulde vorgesehen. Diese Mulde liegt unterhalb der Schwenkachse. Durch Vorschieben der Spitze der Stange wird die Parabolantenne, welche dazu neigt, unter ihrem eigenen Gewicht nach unten zu kippen, angehoben. Weil die Parabolantenne dabei verschwenkt wird, bewegt sich die Mulde, in welcher die Spitze der Verstellstange ruht, auf einem Kreisbogen, nicht aber entlang einer Geraden, insbesondere nicht in Richtung der Verstellstange. Deshalb ist das mit dem Innengewinde versehene Teil an der Halterung, in welchem die Stange mit ihrem Aussengewinde steckt, zweckmäßigerweise eine Mutter, welche verdrehfest, aber in ihrer Neigung begrenzt veränderlich mittels eines Käfigs an der Halterung befestigt ist, so daß die Stange eine der Schwenkbewegung der Parabolantenne folgende Schwenkbewegung vollführen kann.To adjust the inclination of the parabolic antenna, there is preferably a part on the holder with a threaded hole into which an externally threaded rod is screwed, the tip of which abuts against the rear of the parabolic antenna. A trough is provided there so that the position of the tip on the back of the parabolic antenna is clearly defined. This trough lies below the swivel axis. By advancing the tip of the rod, the parabolic antenna, which tends to tip down under its own weight, is raised. Because the parabolic antenna is pivoted, the trough in which the tip of the adjusting rod rests moves on an arc, but not along a straight line, in particular not in the direction of the adjusting rod. Therefore, the part with the internal thread on the holder, in which the rod with its external thread is inserted, is expediently a nut which is attached to the holder by means of a cage so as to be non-rotatable but limited in its inclination, so that the rod has a pivoting movement the parabolic antenna can perform the following pivoting movement.

Die Parabolantenne umfasst einen Reflektorflansch 1 und auf seiner Vorderseite angeordnet einen Reflektor 1a und ein koaxiales Gehäuse 2, welches das Erregersystem der Antenne enthält. Auf der Rückseite des Reflektorflansches 1 befinden sich die Signalausgänge 3 und 4 des Erregersystems sowie zwei spiegelbildlich gleich ausgebildete und angeordnete, lotrechte Wangen 5 und 6, welche symmetrisch in Bezug auf die Achse 7 des Reflektors angeordnet sind. In der Nähe des oberen Randes und des unteren Randes der beiden Wangen 5 und 6 ist je eine Gewindebohrung 8 vorgesehen. Außerdem trägt jede Wange in der Mitte zwischen den Gewindebohrungen 8,genau in Höhe der Achse 7 des Reflektors 1a einen nach aussen abstehenden Zapfen 9. Die beiden gleichachsigen Zapfen 9 definieren die Schwenkachse des Reflektorflansches 1.The parabolic antenna comprises a reflector flange 1 and a reflector 1a and a coaxial housing 2 arranged on its front side, which contains the excitation system of the antenna. On the back of the reflector flange 1 are the signal outputs 3 and 4 of the excitation system and two mirror-image cheeks 5 and 6 of the same design and arrangement, which are arranged symmetrically with respect to the axis 7 of the reflector. A threaded hole 8 is provided in the vicinity of the upper edge and the lower edge of the two cheeks 5 and 6. In addition, each cheek carries a pin 9 projecting outwards in the middle between the threaded bores 8, exactly at the axis 7 of the reflector 1a. The two coaxial pins 9 define the pivot axis of the reflector flange 1.

Die Halterung 10, an welcher der Reflektorflansch 1 befestigt werden soll, umfasst eine Grundplatte 11 und zwei im rechten Winkel von dieser abstehende, spiegelbildlich gleich ausgebildete Wangen 12 und 13, deren Abstand gerade so groß ist, dass die beiden Wangen 5 und 6 des Reflektorflansches 1 zwischen sie eingeschoben werden können. Die beiden Wangen 12 und 13 haben je einen schräg von oben nach unten verlaufenden, nach oben hin offenen Schlitz 14, welcher gerade so breit ist, dass der Zapfen 9 da hinein gleiten kann. Die Schlitze 14 sind an ihrem unteren Ende kreisbogenförmig gerundet, so dass der mit den Zapfen 9 in die Schlitze 14 eingehängte Reflektorflansch 1 um die durch die Zapfen 9 gebildete Achse verschwenkt werden kann (Fig. 2). Oberhalb und unterhalb des Schlitzes 14 ist in jeder der beiden Wangen 12 und 13 ein kreisbogenförmig verlaufendes Langloch 15 bzw. 16 vorgesehen. Diese beiden Langlöcher sind so ausgebildet und angeordnet, dass ihr Krümmungsmittelpunkt auf der Schwenkachse des eingehängten Reflektorflansches 1 liegt.The holder 10, to which the reflector flange 1 is to be fastened, comprises a base plate 11 and two cheeks 12 and 13 projecting at right angles therefrom and having the same mirror image, the spacing of which is just such that the two cheeks 5 and 6 of the reflector flange 1 can be inserted between them. The two cheeks 12 and 13 each have a slot 14 which runs obliquely from top to bottom and is open at the top, which is just wide enough for the pin 9 to slide therein. The slots 14 are rounded in a circular arc at their lower end, so that the reflector flange 1 suspended in the slots 14 with the pins 9 can be pivoted about the axis formed by the pins 9 (FIG. 2). Above and below the slot 14 in each of the two cheeks 12 and 13 there is an arcuate slot 15 and 16 respectively. These two elongated holes are designed and arranged such that their center of curvature lies on the pivot axis of the suspended reflector flange 1.

Zum Befestigen der Halterung 10 an einem Standrohr 17 sind an der Grundplatte 11 zwei Paar Klemmschellen 18 angebracht, mit welchen die Halterung 10 durch oberen Anschlag an der Grundplatte 11 fixiert am Standrohr 17 festgeklemmt werden kann. Ist das geschehen, kann der Reflektorflansch 1 mit dem Zapfen 9 in die Schlitze 14 der Halterung 10 eingehängt werden. Zur Einstellung der Neigung ist eine Stange 19 vorgesehen, die auf einem Teil ihrer Länge ein Aussengewinde 20 trägt, mit welchem sie in eine Mutter 21 eingedreht ist,welche in einem Käfig 22 gelagert ist, der in ein Loch der Grundplatte 11 der Halterung 10 eingesetzt ist. Die Spitze 23 der Stange ruht in einer tiefen Mulde 24, welche der Rückseite des Reflektorflansches 1 angeformt ist. Durch Verdrehen der Stange 19 kann die Parabolantenne mehr oder weniger stark angehoben werden, wobei die Stange 19 der Schwenkbewegung folgen kann, weil die Mutter 21 im Käfig 22 begrenzt verschwenkbar gelagert ist.To fasten the bracket 10 to a standpipe 17, two pairs of clamps 18 are attached to the base plate 11, with which the holder 10 can be clamped to the standpipe 17 by an upper stop on the base plate 11. Once this has been done, the reflector flange 1 can be hung into the slots 14 of the holder 10 with the pin 9. To adjust the inclination a rod 19 is provided, which carries on part of its length an external thread 20, with which it is screwed into a nut 21, which is mounted in a cage 22 which is inserted into a hole in the base plate 11 of the holder 10. The tip 23 of the rod rests in a deep recess 24, which is molded onto the back of the reflector flange 1. By rotating the rod 19, the parabolic antenna can be lifted more or less strongly, the rod 19 being able to follow the pivoting movement because the nut 21 is pivotably supported in the cage 22 to a limited extent.

In der Wange 13 ist oberhalb des Langloches 16 ein weiteres bogenförmiges Langloch 25 vorgesehen, welches den Blick auf einen Skalenstrich 26 freigibt, welcher auf der dahinter liegenden Wange 5 des Reflektorflansches angebracht ist und das Ablesen einer Winkelskala 27 gestattet, welche längs des Randes des Langloches 25 auf der Wange 13 angebracht ist. Nach Einstellen der gewünschten Reflektorneigung wird diese Neigung durch Eindrehen von Klemmschrauben 28 in die Gewindebohrungen 8 fixiert. In the cheek 13 a further arcuate elongated hole 25 is provided above the elongated hole 16, which reveals the view of a scale line 26, which is attached to the cheek 5 behind the reflector flange and allows the reading of an angular scale 27, which runs along the edge of the elongated hole 25 is attached to the cheek 13. After setting the desired reflector inclination, this inclination is fixed by screwing the clamping screws 28 into the threaded bores 8.
