Description

La présente invention se rapporte à un support d'antenne orientable, constitué d'un élément porteur et d'un dispositif de couplage pour coupler l'antenne à l'élément porteur, ce dispositif de couplage comportant un axe de rotation vertical solidaire de l'élément porteur et un axe de rotation horizontal solidaire de l'antenne.The present invention relates to an orientable antenna support, consisting of a carrier element and a coupling device for coupling the antenna to the carrier element, this coupling device comprising a vertical axis of rotation integral with the carrier element and a horizontal axis of rotation integral with the antenna.

La présente invention concerne également les antennes montées sur de tels supports.The present invention also relates to the antennas mounted on such supports.

De tels supports d'antenne permettent d'utiliser, comme élément porteur, le local qui abrite les équipements nécessaires au fonctionnement de l'antenne; le prix du support d'antenne se trouve ainsi sérieusement réduit par rapport aux supports d'antenne dont l'élément porteur est conçu uniquement pour le support.Such antenna supports make it possible to use, as a carrier element, the room which houses the equipment necessary for the operation of the antenna; the price of the antenna support is thus seriously reduced compared to antenna supports whose carrier element is designed only for the support.

De tels supports d'antenne sont connus, par exemple par la demande de brevet allemand DOS 2 809 158 et, plus précisément, par la description qui est faite à l'aide de la figure 8. Dans ces supports d'antenne connus l'axe horizontal de rotation de l'antenne est écarté de l'axe de rotation vertical au moyen d'une première paire de barres de soutien de même longueur qui joint l'extrémité supérieure de l'axe vertical à une extrémité de l'axe horizontal et d'une seconde paire qui joint l'extrémité inférieure de l'axe vertical à l'autre extrémité de l'axe horizontal. L'axe horizontal, et donc l'antenne, sont ainsi écartés de l'axe vertical, et donc de l'élément porteur, pour éviter que la partie arrière de l'antenne et en particulier son câble d'alimentation ne réduisent les possibilités de réglage en site en venant buter contre l'axe vertical. Malgré sa simplicité un tel support d'antenne est cher en raison, en particulier, du coût des barres et de leur assemblage.Such antenna supports are known, for example from the German patent application DOS 2 809 158 and, more precisely, by the description which is made with the aid of FIG. 8. In these known antenna supports the horizontal axis of rotation of the antenna is separated from the vertical axis of rotation by means of a first pair of support bars of the same length which joins the upper end of the vertical axis to one end of the horizontal axis and a second pair which joins the lower end of the vertical axis to the other end of the horizontal axis. The horizontal axis, and therefore the antenna, are thus spaced from the vertical axis, and therefore from the carrier element, to prevent the rear part of the antenna and in particular its power cable from reducing the possibilities adjustment in site coming to abut against the vertical axis. Despite its simplicity, such an antenna support is expensive due, in particular, to the cost of the bars and their assembly.

Le but de la présente invention est de réduire le prix de revient du support d'antenne dont il a été question au début de cette description. Ceci est obtenu en réduisant à trois le nombre des barres de soutien nécessaires.The object of the present invention is to reduce the cost price of the antenna support which was mentioned at the beginning of this description. This is achieved by reducing the number of support bars required to three.

Selon l'invention un support d'antenne du type indiqué au début de cette description, conduit à ce résultat en disposant les deux axes de rotation dans un même plan mais de telle manière que l'une des extrémités de l'axe horizontal soit confondue avec l'extrémité supérieure de l'axe vertical.According to the invention an antenna support of the type indicated at the beginning of this description, leads to this result by arranging the two axes of rotation in the same plane but in such a way that one of the ends of the horizontal axis is merged with the upper end of the vertical axis.

La présente invention sera mieux comprise et d'autres caractéristiques apparaîtront à l'aide de la description ci-après et de la figure s'y rapportant qui est une vue schématique d'un support d'antenne selon l'invention.The present invention will be better understood and other characteristics will appear with the aid of the description below and the related figure which is a schematic view of an antenna support according to the invention.

La figure montre un élément porteur 1 constitué par un cadre métallique (container dans la littérature anglo-saxonne). Ce cadre, placé à plat sur le sol, sert d'appui à une antenne parabolique de télécommunications, 2, qui y est reliée par l'intermédiaire d'un dispositif de couplage 3, constitué d'une ensemble tubulaire, 4, en forme de triangle, ABC, rectangle en A et de deux barres de longueur réglable 5, 6.The figure shows a carrier element 1 consisting of a metal frame (container in the Anglo-Saxon literature). This frame, placed flat on the ground, serves as a support for a parabolic telecommunications antenna, 2, which is connected to it by means of a coupling device 3, consisting of a tubular assembly, 4, in the form triangle, ABC, rectangle in A and two bars of adjustable length 5, 6.

Le cadre 1 sert à la fois d'abri pour le matériel électronique associé à l'antenne et de salle de travail pour le personnel affecté à l'antenne.The frame 1 serves both as a shelter for the electronic equipment associated with the antenna and as a work room for the personnel assigned to the antenna.

Le cadre 1 présente une face verticale, sensiblement carrée, munié, à ses deux angles inférieurs et à l'un de ses angles supérieurs, de pattes de fixation 10, 11, 12. Les pattes de fixation, dans l'exemple décrit, sont réunies au cadre 1 à l'aide de boulons et d'écrous non représentés.The frame 1 has a vertical face, substantially square, provided, at its two lower angles and at one of its upper angles, with fixing lugs 10, 11, 12. The fixing lugs, in the example described, are joined to frame 1 using bolts and nuts not shown.

L'ensemble tubulaire 4, constitué essentiellement de trois barres cylindriques disposées selon les trois côtés du triangel ABC et soudées les unes aux autres, peut pivoter autour de son côté AC disposé verticalement. La barre AC traverse la patte supérieure 12 qui forme collier; cette barre repose, à son extrémité inférieure en forme de pivot, dans une crapaudine taillée dans la patte 10.The tubular assembly 4, essentially consisting of three cylindrical bars arranged along the three sides of the triangel ABC and welded to each other, can pivot around its side AC arranged vertically. The bar AC crosses the upper tab 12 which forms a collar; this bar rests, at its lower end in the shape of a pivot, in a plate cut in the tab 10.

Deux paliers d'axe 40, 41, solidaires de l'antenne 2, respectivement disposés au voisinage des extrémités de la barre AB, permettent le pivotement de l'antenne 2 autour de cette barre.Two axis bearings 40, 41, integral with the antenna 2, respectively arranged in the vicinity of the ends of the bar AB, allow the antenna 2 to pivot around this bar.

La barre BC a un simple rôle de barre de soutien de l'antenne.The BC bar has a simple role of antenna support bar.

Les barres de longueur réglable 5, 6 sont munies à leurs extrémités de joints de cardan symbolisés, sur la figure, par des boules. Des vérins à vis à commande manuelle, 50, 60, permettent le réglage de la longueur des barres 5 et 6.The adjustable length bars 5, 6 are provided at their ends with universal joints symbolized, in the figure, by balls. Manually operated screw jacks, 50, 60, allow adjustment of the length of bars 5 and 6.

Les variations de longueur de la barre 5 déterminent le déplacement en azimut de l'antenne par rotation autour de la barre AC qui constitue ainsi l'axe de rotation vertical ou axe de rotation en azimut de l'antenne; à cet effet la barre 5 est fixée par l'intermédiaire de ses deux joints de cardan d'une part à la patte 11, sensiblement au même niveau que l'extrémité inférieure (42) de l'axe de rotation vertical (AC), et d'autre part à l'angle B de l'ensemble tubulaire 4.The variations in length of the bar 5 determine the displacement in azimuth of the antenna by rotation around the bar AC which thus constitutes the vertical axis of rotation or axis of rotation in azimuth of the antenna; for this purpose the bar 5 is fixed by means of its two universal joints on the one hand to the lug 11, substantially at the same level as the lower end (42) of the vertical axis of rotation (AC), and on the other hand at the angle B of the tubular assembly 4.

Les variations de longueur de la barre 6 déterminent le déplacement en site de l'antenne par rotation autour de la barre AB qui constitue ainsi l'axe de rotation horizontal ou axe de rotation en site de l'antenne; à cet effet la barre 6 est fixée par l'intermédiaire de ses deux joints de cardan d'une part à l'angle C de l'ensemble tubulaire 4 et d'autre part à l'arrière de l'antenne en un point suffisamment écarté de la droite passant par les extrémités de la barre AB pour que l'effort à fournir pour faire pivoter l'antenne autour de la barre AB soit faible.The variations in length of the bar 6 determine the displacement in elevation of the antenna by rotation around the bar AB which thus constitutes the horizontal axis of rotation or axis of rotation in elevation of the antenna; for this purpose the bar 6 is fixed by means of its two cardan joints on the one hand at the angle C of the tubular assembly 4 and on the other hand at the rear of the antenna at a point sufficiently away from the straight line passing through the ends of the bar AB so that the effort required to rotate the antenna around the bar AB is low.

Il est à noter que, telle qu'elle est fixée sur l'ensemble tubulaire 4, l'antenne est sensiblement centrée sur le milieu de AB et est donc décalée dans le plan ABC, par rapport à l'axe de rotation vertical AC; une telle disposition permet d'éviter que la partie arrière de l'antenne et en particulier le câble d'alimentation, non représenté, ne réduise les possibilités de réglage en site, en venant buter contre l'axe vertical.It should be noted that, as it is fixed on the tubular assembly 4, the antenna is sensitive ment centered on the middle of AB and is therefore offset in the plane ABC, relative to the vertical axis of rotation AC; such an arrangement makes it possible to prevent the rear part of the antenna and in particular the power cable, not shown, from reducing the possibilities of adjustment in elevation, by abutting against the vertical axis.

A titre indicatif l'antenne parabolique de télécommunications qui a servi d'exemple pour la description est une antenne de 3 mètres de diamètre travaillant dans la bande des 11 GHz et le local est un cadre métallique d'environ 2 mètres de large et 3 mètres de long.As an indication, the parabolic telecommunications antenna which served as an example for the description is a 3 meter diameter antenna working in the 11 GHz band and the room is a metal frame approximately 2 meters wide and 3 meters long.

D'autres réalisations que celle selon la figure peuvent être envisagées sans sortir du cadre de l'invention. C'est ainsi que la barre AB peut être supprimée ainsi que les paliers d'axe 40 et 41, les barres AC et BC étant alors respectivement articulées en A et B sur l'antenne 2 de manière que l'axe de rotation en site de l'antenne reste l'axe AB. De même les vérins manuels à vis 50, 60 peuvent être remplacés par des vérins hydrauliques.Other embodiments than that according to the figure can be envisaged without departing from the scope of the invention. This is how the bar AB can be omitted as well as the axis bearings 40 and 41, the bars AC and BC then being respectively articulated at A and B on the antenna 2 so that the axis of rotation in elevation of the antenna remains the axis AB. Similarly, the manual screw jacks 50, 60 can be replaced by hydraulic jacks.

Il peut également être envisagé de supprimer la barre de soutien BC, à condition de conserver les barres AB et AC; mais les contraintes mécaniques au point A posent alors des problèmes de réalisation pour éviter le dépointage de l'antenne sous l'effet du vent.It can also be envisaged to remove the support bar BC, provided that the bars AB and AC are kept; but the mechanical constraints at point A then pose production problems in order to avoid the depointing of the antenna under the effect of the wind.

L'invention s'applique d'une façon générale aux antennes orientables aussi bien lorsque l'orientation de l'antenne ne doit varier que pour des réglages, que lorsque l'orientation de l'antenne doit varier de façon continue pour effectuer un balayage.The invention applies generally to orientable antennas as well when the orientation of the antenna must vary only for adjustments, as when the orientation of the antenna must vary continuously to carry out a scan. .
