Description

La présente invention concerne un support d'antenne pour la réception directe d'émissions de télévision provenant d'un satellite géostationnaire. L'invention concerne également une antenne portée par un tel support.The present invention relates to an antenna support for the direct reception of television broadcasts from a geostationary satellite. The invention also relates to an antenna carried by such a support.

Dans le cas de la réception d'émissions de télévision, la forte augmentation de la puissance d'émission des satellites a permis de réduire considérablement la taille des antennes, de forme générale parabolique, et a permis d'envisager la réception directe des émissions de télévision par satellite, chaque poste récepteur de télévision pouvant alors être associé à une antenne de faible taille braquée sur le satellite géostationnaire émetteur.In the case of reception of television broadcasts, the sharp increase in the transmission power of satellites has made it possible to considerably reduce the size of the antennas, of general parabolic shape, and has made it possible to envisage the direct reception of broadcasts satellite television, each television receiving station can then be associated with a small antenna directed at the transmitting geostationary satellite.

Le satellite étant géostationnaire, l'antenne peut être braquée une fois pour toutes dans la direction de ce satellite émetteur. Cependant, il est nécessaire de pouvoir régler cette antenne, en azimut èt en site, au moment de son installation, de manière précise mais simple afin que ce réglage puisse être réalisé par une personne non expérimentée.The satellite being geostationary, the antenna can be turned once and for all in the direction of this transmitting satellite. However, it is necessary to be able to adjust this antenna, in azimuth and on site, at the time of its installation, in a precise but simple manner so that this adjustment can be carried out by an inexperienced person.

Par ailleurs, il peut être aussi nécessaire de pouvoir modifier ces réglages de manière à pointer l'antenne sur un autre satellite, de position différente par rapport à celui sur lequel l'antenne était initialement réglée. Cependant ce cas reste relativement exceptionnel, car, compte tenu des problèmes de langue, les utilisateurs des récepteurs de télévision ne seront amenés à recevoir le plus souvent que les émissions d'un seul satellite.Furthermore, it may also be necessary to be able to modify these settings so as to point the antenna at another satellite, with a different position compared to that on which the antenna was initially adjusted. However, this case remains relatively exceptional, because, taking into account language problems, the users of television receivers will most often only have to receive broadcasts from a single satellite.

On a déjà proposé des supports d'antenne de faible taille. Mais ces supports connus sont des miniaturisations des suports des grandes antennes des centres de réception, ces supports étant munis d'éléments de réglages onéreux et relativement compliqués. De plus, dans le cas des antennes de faible taille destinées à la réception d'émissions de télévision, ces éléments de réglages compliqués se révèlent pratiquement inutiles, puisque ils ne servent que lors de l'installation de l'antenne, et dans le cas très rare où l'on désire changer de satellite émetteur.Small antenna supports have already been proposed. However, these known supports are miniaturizations of the supports of the large antennas of the reception centers, these supports being provided with expensive and relatively complicated adjustment elements. Furthermore, in the case of small antennas intended for the reception of television broadcasts, these complicated adjustment elements prove to be practically useless, since they are used only during the installation of the antenna, and in the very rare case where you wish to change the transmitting satellite.

Le support d'antenne selon l'invention est simple et économi que et permet à l'utilisateur un réglage facile de l'azimut et du site de cette antenne lors de son installation.The antenna support according to the invention is simple and economical and allows the user an easy adjustment of the azimuth and the site of this antenna during its installation.

Le support d'antenne de télécommunication par satellite géostationnaire selon l'invention est caractérisé en ce qu'il comprend : un poteau de direction fixé par rapport au sol et pouvant tourner autour de son axe longitudinal pour régler l'azimut de l'antenne, et un quadrilatère articulé dont un côté constitue une partie de l'antenne et un autre côté est une partie du poteau, la longueur de cette partie étant réglable et déterminant le site de l'antenne.The geostationary satellite telecommunication antenna support according to the invention is characterized in that it comprises: a steering pole fixed relative to the ground and able to rotate around its longitudinal axis to adjust the azimuth of the antenna, and an articulated quadrilateral of which one side constitutes a part of the antenna and another side is a part of the pole, the length of this part being adjustable and determining the site of the antenna.

De préférence le poteau est vertical.Preferably the post is vertical.

Le poteau peut être fixé à un mur par l'intermédiaire de brides. Il peut également être fixé à un autre poteau enfoncé dans le sol également par l'intermédiaire de brides. Dans une autre réalisation, l'extrémité inférieure du poteau est introduite dans un trou d'axe vertical d'un socle, ce poteau pouvant tourner autour de son axe dans son logement dans le socle, des moyens étant cependant prévus pour immobiliser ledit poteau.The post can be fixed to a wall by means of flanges. It can also be fixed to another post driven into the ground also by means of flanges. In another embodiment, the lower end of the pole is introduced into a hole with a vertical axis of a base, this pole being able to rotate about its axis in its housing in the base, means being however provided for immobilizing said pole.

D'autres caractéristiques et avantages de l'invention ressortiront de la description suivante donnée à titre d'exemple et illustrée par les figures annexées qui représentent :

  • - les figures lA, 1B et 1C, un premier mode de réalisation d'un support selon l'invention, muni d'une antenne parabolique,
  • - la figure 2, un second mode de réalisation d'un support selon l'invention,
  • - les figures 3A, 3B, un troisième mode de réalisation d'un support selon l'invention.
Other characteristics and advantages of the invention will emerge from the following description given by way of example and illustrated by the appended figures which represent:
  • FIGS. 1A, 1B and 1C, a first embodiment of a support according to the invention, provided with a parabolic antenna,
  • FIG. 2, a second embodiment of a support according to the invention,
  • - Figures 3A, 3B, a third embodiment of a support according to the invention.

Une antenne paraboloidale 10 est symbolisée figure lA. Cette antenne est montée sur son support et l'axe de son réflecteur paraboloide est pointé vers le satellite émetteur.A paraboloidal antenna 10 is symbolized in FIG. 1A. This antenna is mounted on its support and the axis of its reflector dish is pointed at the transmitting satellite.

Le support comporte un tube 1 dont les extrémités sont serrées dans des colliers 2. Ces colliers comportent deux parties en forme d'arc de cercle qui sont maintenues autour du tube 1 par des boulons de serrage.The support comprises a tube 1, the ends of which are clamped in collars 2. These collars comprise two parts in the form of an arc of a circle which are held around the tube 1 by tightening bolts.

Une des deux parties des colliers 2 est solidaire d'un pied 4 par l'intermédiaire duquel les colliers 2, et donc le tube 1 sont fixés sur un mur vertical 11.One of the two parts of the collars 2 is integral with a foot 4 by means of which the collars 2, and therefore the tube 1 are fixed to a vertical wall 11.

Sur cette figure 1C, les deux demi-brides 3a ont été représentées en coupe transversale, positionnées autour du tube à l'aide des deux boulons 9. Le bras 7 comporte deux lames métalliques 7a identiques. Ces deux lames sont à l'une de leurs extrémités, serrées l'une contre l'autre entre les deux demi-brides grâce à l'un des boulons de serrage 9a.In this FIG. 1C, the two half-flanges 3a have been shown in cross section, positioned around the tube using the two bolts 9. The arm 7 has two identical metal blades 7a. These two blades are at one of their ends, clamped one against the other between the two half-flanges by means of one of the tightening bolts 9a.

Les deux lames 7a sont préformées de manière à constituer un triangle isocèle dont le sommet est sur le boulon de serrage 9a et la base, la droite active reliant les deux oreilles 8a fixées à l'arrière de l'antenne 10.The two blades 7a are preformed so as to constitute an isosceles triangle, the apex of which is on the tightening bolt 9a and the base, the active line connecting the two ears 8a fixed to the rear of the antenna 10.

Les oreilles 8a sont solidaires de l'antenne 10 à une distance prédéterminée de l'oreille supérieure 6, de manière à former, de préférence, un triangle isocèle dont le sommet est l'oreille supérieure 6 et la base, ladite droite fictive reliant les deux oreilles 8a.The ears 8a are integral with the antenna 10 at a predetermined distance from the upper ear 6, so as to preferably form an isosceles triangle the apex of which is the upper ear 6 and the base, said fictitious straight line connecting the two ears 8a.

Les extrémités des lames métalliques sont maintenues sur les oreilles 8a par des boulons de serrage.The ends of the metal blades are held on the ears 8a by tightening bolts.

Grâce à des rondelles ou d'autres moyens associés aux boulons, le bras 7 est articulé d'une part à la bride 3 selon un axe horizontal et d'autre part aux oreilles 8a de l'antenne 10, selon un axe horizontal 31. iThanks to washers or other means associated with the bolts, the arm 7 is articulated on the one hand to the flange 3 along a horizontal axis and on the other hand to the ears 8a of the antenna 10, along a horizontal axis 31. i

Dans le cas de la figure lA, lorsqu'on fait coulisser la bride 3 vers le haut, le bras 7 transmet une force à l'antenne 10 qui est suffisante pour la faire pivoter autour de l'axe 6, l'axe 10a du paraboloïde se rapprochant alors de la position verticale. Au contraire, lorsque la bride 3 coulisse vers le bas, l'antenne 10 pivote dans un sens tel que l'axe 10a se rapproche de la position horizontale.In the case of FIG. 1A, when the flange 3 is slid upwards, the arm 7 transmits a force to the antenna 10 which is sufficient to make it pivot around the axis 6, the axis 10a of the paraboloid approaching the vertical position. On the contrary, when the flange 3 slides downwards, the antenna 10 pivots in a direction such that the axis 10a approaches the horizontal position.

La partie lb du poteau 1 entre la bride 3 et le bras 5 forme un côté d'un quadrilatère à trois articulations 30, 31 et 6a dont les trois autres côtés sont les bras 5 et 7 et la droite fictive reliant l'oreille 6 à un point de l'axe 31. C'est en faisant varier la longueur de la partie 16 qu'on fait pivoter l'axe 10a.The part 1b of the post 1 between the flange 3 and the arm 5 forms one side of a quadrilateral with three joints 30, 31 and 6a, the other three sides of which are the arms 5 and 7 and the fictitious line connecting the ear 6 to a point on the axis 31. It is by varying the length of the part 16 that the axis 10a is made to pivot.

La direction de l'axe de symétrie 10a du paraboloïde de l'antenne 10 dépend donc de la position de la bride 3 sur le tube 1. C'est ainsi, par le déplacement de cette bride, qu'on effectue le réglage de la direction de l'axe 10a dans un plan vertical, c'est-à-dire de son site.The direction of the axis of symmetry 10a of the dish of the antenna 10 therefore depends on the position of the flange 3 on the tube 1. Thus, by the movement of this flange, the adjustment of the direction of axis 10a in a vertical plane, that is to say of its site.

Le tube 1 pouvant pivoter autour de son axe de symétrie, et l'antenne 10 étant solidaire du tube 1 par l'intermédiaire des bras 5 et 7, cette antenne 10 peut pivoter autour de l'axe la. Ce pivotement du tube 1 permet dont d'orienter l'azimut de l'antenne 10.The tube 1 being able to pivot about its axis of symmetry, and the antenna 10 being integral with the tube 1 via the arms 5 and 7, this antenna 10 can pivot around the axis la. This pivoting of the tube 1 makes it possible to orient the azimuth of the antenna 10.

Lors de l'installation de l'antenne 10, on fixe donc dans un premier temps le support de l'antenne 10, par l'intermédiaire des pieds 4 des colliers 2, sur le mur 11, par exemple de manière que le tube 1 soit dans un plan méridien.During the installation of the antenna 10, the antenna support 10 is therefore initially fixed, by means of the feet 4 of the collars 2, on the wall 11, for example so that the tube 1 either in a meridian plane.

L'installateur peut ensuite agir sur la bride 3 de manière que l'axe 10a fasse avec la verticale du lieu où est montée l'antenne, un angle égal à la latitude de l'emplacement de l'antenne.The installer can then act on the flange 3 so that the axis 10a forms with the vertical of the place where the antenna is mounted, an angle equal to the latitude of the location of the antenna.

La position de l'axe du paraboloide étant liée à la position de la bride 3, il est possible de repérer la position de cet axe en graduant le tube 1 par des repères 15, chaque repère correspondant à une position précise de la bride 3 et donc du site de l'axe du paraboloïde.The position of the axis of the paraboloid being linked to the position of the flange 3, it is possible to locate the position of this axis by graduating the tube 1 with marks 15, each mark corresponding to a precise position of the flange 3 and therefore from the site of the paraboloid axis.

Après un étalonnage initial, une table de concordance donne le repère 15 correspondant à la latitude - connue - du lieu où doit être placé l'antenne 10. Ainsi l'axe 10a du paraboloïde est dans un plan sensiblement parallèle au plan de l'équateur. Les satellites géostationnaires étant dans le plan de l'équateur et à une latitude sensiblement égale à 36.000 Km, il est possible de sélectionner le satellite à recevoir en faisant tourner l'antenne 10 autour de l'axe vertical la, c'est-à-dire le tube 1 à l'intérieur des colliers 2.After an initial calibration, a concordance table gives the reference 15 corresponding to the latitude - known - of the place where the antenna 10 must be placed. Thus the axis 10a of the paraboloid is in a plane substantially parallel to the plane of the equator . The geostationary satellites being in the plane of the equator and at a latitude substantially equal to 36,000 km, it is possible to select the satellite to be received by rotating the antenna 10 around the axis vertical la, that is to say the tube 1 inside the collars 2.

A cet effet, les colliers 2 peuvent être gradués de manière qu'un repère de cette graduation corresponde à un satellite géostationnaire émetteur.For this purpose, the collars 2 can be graduated so that a mark of this graduation corresponds to a transmitting geostationary satellite.

Ce réglage peut être affiné en connectant l'antenne 10 à un récepteur de contrôle et en modifiant légèrement les réglages initiaux de manière à obtenir la meilleure image possible.This adjustment can be refined by connecting the antenna 10 to a control receiver and by slightly modifying the initial settings so as to obtain the best possible image.

Les réglages terminés, l'antenne est immobilisée en serrant tous les boulons des colliers 2 et de la bride 3.Once the settings are complete, the antenna is immobilized by tightening all the bolts of the collars 2 and the flange 3.

La figure 2 représente un second mode de réalisation du support selon l'invention.FIG. 2 represents a second embodiment of the support according to the invention.

Dans ce cas, le support de la figure lA est fixé par l'intermédiaire des pieds 4 des colliers 2 sur un autre poteau 16 qui, dans une réalisation préférée est de section carrée. Ce poteau 16 est planté dans une dalle horizontale de béton 33. Ce mode de réalisation permet par exemple la fixation de l'antenne dans un jardin.In this case, the support of FIG. 1A is fixed by means of the feet 4 of the collars 2 on another post 16 which, in a preferred embodiment is of square section. This post 16 is planted in a horizontal concrete slab 33. This embodiment allows for example the fixing of the antenna in a garden.

La figure 3A représente un troisième mode de réalisation de l'invention. Ici le tube 1 muni de son bras 5 et de sa bride 3 n'a plus de collier de fixation, mais a son extrémité inférieure enfichée dans un socle comportant un pied 20.FIG. 3A represents a third embodiment of the invention. Here, the tube 1 provided with its arm 5 and its flange 3 no longer has a fixing collar, but at its lower end inserted in a base comprising a foot 20.

Ce pied 20 comporte une partie cylindrique creuse 22 dans laquelle est positionnée le tube 1, cette partie cylindrique est maintenue en position verticale sur une plaque horizontale 23 par quatre pièces de soutien 21. Ce pied est représenté en vue de dessus sur la figure 3B.This foot 20 comprises a hollow cylindrical part 22 in which the tube 1 is positioned, this cylindrical part is held in a vertical position on a horizontal plate 23 by four support pieces 21. This foot is shown in top view in FIG. 3B.

La tranche de la partie cylindrique 22 est graduée par des repères 17 équivalents à ceux disposés sur les colliers 2 des figures lA et 2, le tube 1 pouvant pivoter autour de son axe de symétrie à l'intérieur de cette partie cylindrique de manière à régler l'azimut de l'antenne 10. Des moyens de blocage du tube 1 telle qu'une vis d'arrêt, sont associés à cette partie cylindrique 22.The edge of the cylindrical part 22 is graduated by marks 17 equivalent to those arranged on the collars 2 of FIGS. 1A and 2, the tube 1 being able to pivot around its axis of symmetry inside this cylindrical part so as to adjust the azimuth of the antenna 10. Means for blocking the tube 1, such as a stop screw, are associated with this cylindrical part 22.

La plaque 23 est fixée sur une dalle horizontale 30. Ces supports d'antenne permettent donc un réglage facile de l'antenne 10 et sont plus particulièrement adaptés, quoique non exclusivement, à la mise en place d'antennes destinées à être orientées définitivement vers le même satellite.The plate 23 is fixed to a horizontal slab 30. These antenna supports therefore allow easy adjustment of the antenna 10 and are more particularly adapted, although not exclusively, to the installation of antennas intended to be oriented definitively towards the same satellite.

Ces types de support d'antenne sont plus particulièrement adaptés aux antennes de réception directe d'émission télévision par satellite.These types of antenna support are more particularly suited to antennas for direct reception of satellite television transmissions.
