- a loop 62 of the elastically deformable lip 60 located on one side of the connecting wall 12 bears against the lateral face 52 of the antenna 2 disposed on this side of the wall.
- This contact forms a means of sealing the antenna support 1, avoiding an intrusion of dirt and rainwater in particular, and also avoiding taking wind antenna 1 support.

- the bars 64 are fixed on the rear face of the connecting wall 12 so as to extend substantially perpendicularly, and they are respectively disposed in a housing sleeve 66 integral with the mast.
- Fixing the bars 64 on the connecting wall is via a wafer 64b extending substantially perpendicularly to the free end of the bar 64, that is to say at the opposite end of the end configured to slide within the housing 66.
- This wafer 64b may have a curved shape to match the profile of the inner face of the connecting wall against which it has been plated.
- Each bar and each sheath have a plurality of orifices 65 (in particular visible in FIG. 11a) respectively disposed along the bar and the sleeve in the direction of radial adjustment of the wall relative to the mast, which the operator can correspond to each other to increase the distance between the mast 18 and the connecting wall 12.

- this radial adjustment means 63 makes it possible to position the connecting walls 12 and the loops 62 of the deformable elastic lips 60 more or less at a distance from the mast 18, and therefore to adapt to antennas of different widths from one mast to another, ensuring that the loops 62 rest on the lateral faces 52 of the antennas 2.
- the same mat 18 and the same connecting walls 12 can be used to seal a second portion 6 using antennas 2 of different widths. This helps to standardize the support components antennas and thus keep the cost as low as possible.
- the free end 67 of the second part 38 of the mast 18, that is to say the end opposite the articulation plate with the first part 32 of the mast 18, has a first fastener 68 which has three sleeves 66, for example of substantially square section, and in which a bar 64 of equivalent section to that of the sleeves and slightly smaller in size can be respectively disposed for more or less power move the bar from the center of the antenna support 1 by a telescopic arrangement of the bar in the sleeve.

- the lower end of the second portion of the mast, opposite the free end, also has adjustment means. the radial position of the walls as described above. It may be interesting that these means of adjustment at the lower end differs from the shape of the full sleeve of the free end, in that the adjustment means take the form of receptacles 70, also configured to cooperate with bars this time brought to the corresponding lower end of the connecting walls 12 and allow fixing by bolting when the adequate radial position is found, but having a U-shaped section open towards the opposite free end.
- Each receptacle thus has a U-shaped section with a base facing the first portion 4 of the antenna support and two side walls 71 parallel to each other and forming lateral holding means of the bar 64 when the latter is engaged in the housing.
- the radial adjustment function is carried out, the receptacles having on their lateral walls 71 orifices 65 for receiving bolting means, while allowing an axial positioning clearance, that is to say in the direction of extension of the mast, first adjustment means 63a in the upper part of the mast and second adjustment means 63b in the lower part of the mast.
- first adjustment means in the upper part and second adjustment means in the lower part of the sleeves and bars associated with the free end of the second part of the mat on the one hand and the receptacles and bars associated with the lower end of the second part of the mat on the other hand.
- the orifices 65 formed in the side walls of the receptacles 70 will advantageously have an oblong shape, with the major axis substantially parallel to the direction of elongation of the mast, to allow a mounting clearance between the connecting wall and the mast.
- FIGS. 14 to 16 three types of panel antennas, which are distinct from one another by their dimensions, have been illustrated.
- the radial adjustment means according to the invention allows the connecting wall to take predetermined radial positions, so that the flexible portions 60 forming the sealing lip are carried by the loop 62 made at their free end, on the face. side of an antenna.
- the shape of these antennas can vary, in particular their front face, according to the required radiocommunication transmission configurations, but it should be noted that the lateral faces serve as support face for the flexible parts.
- the adjustment in radial position allows to more or less separate the connecting wall of the mast and thus ensure that the loops are in contact, without being too constrained, the side face of the antenna. For example, we can provide:
- FIG. 13 may be an example of 600 millimeters for a thickness e3 of 200 millimeters ( Figure 16), the predetermined radial position of the connecting walls being then the furthest possible from the mast ( Figure 13);
- the width 11 of which may be an example of 300 millimeters for a thickness el of 140 millimeters (FIG.

- Figures 5 and 6 illustrate intermediate positions between the two extreme positions described above, wherein the second elongation direction 7 of the second portion 6 is inclined relative to the first elongation direction 5 of the first portion.
- An actuating means 72 is associated with the antenna support 1 to facilitate the passage of the second portion from one position to the other, and to retain this second portion against the effect of gravity, as well to maintain it in the extreme position of the mounting configuration only to maintain it in stable intermediate positions.

Description
ENSEMBLE COMPRENANT AU MOINS UN SUPPORT ET UNE PLURALITE D'ANTENNES DE RADIOCOMMUNICATION Le domaine de la présente invention est celui des supports et antennes pour réseaux de radiocommunications mobiles. The field of the present invention is that of supports and antennas for mobile radiocommunications networks. BACKGROUND OF THE INVENTION
La communication mobile implique une couverture du territoire au moyen d'antennes disposées sur celui-ci. Le nombre de ces antennes détermine le taux de couverture d'un opérateur de radiocommunication et ces antennes doivent être installées à la fois en milieu rural et en milieu urbain. Les antennes sont installées au moyen de supports qui permettent l'orientation correcte des antennes et la fixation de celles-ci. Mobile communication involves coverage of the territory by means of antennas placed on it. The number of these antennas determines the coverage rate of a radiocommunication operator and these antennas must be installed in both rural and urban areas. The antennas are installed by means of supports which allow the correct orientation of the antennas and the fixation of these.
Pour des raisons de bonne propagation des ondes de radiocommunication par les antennes, le support d'antennes doit être disposé dans un espace dégagé. Il en résulte un risque de prise au vent des antennes qui peut être contraignante pour le support qui s'étend principalement verticalement dans sa position opérationnelle d'émission. Et cela s'inscrit dans un besoin pour l'ensemble formé par un support et ces antennes associées de se fondre dans le paysage, en prenant en compte un aspect environnemental ainsi que visuel. For reasons of good propagation of the radiocommunication waves by the antennas, the antenna support must be arranged in an open space. This results in a risk of taking wind antennas that can be binding for the support that extends mainly vertically in its operational position of emission. And this is part of a need for all formed by a support and associated antennas to blend into the landscape, taking into account an environmental aspect as well as visual.
Par ailleurs, selon la zone d'implantation et la couverture à réaliser, c'est-à-dire l'étendue de la zone géographique dans laquelle on souhaite pouvoir émettre à partir des antennes du dispositif implanté, les antennes peuvent présenter des dimensions différentes et de fait des poids différents. Il est notamment connu des antennes panneaux, présentant une forme de parallélépipède, qui sont fixées sur le support pour être disposées verticalement dans la configuration opérationnelle d'émission des antennes. On comprend que la possibilité d'avoir des antennes de dimensions différentes d'une application à l'autre implique pour le fabricant de support d'antennes de proposer un nombre conséquent de supports aptes à permettre respectivement la fixation d'antennes d'un certain type.
Ces antennes forment des ensembles volumineux et lourds, qui notamment en milieu urbain sont difficiles à installer. En effet, l'installation de ce type d'ensemble intervient souvent au sommet d'immeuble ou de bâtiment. Compte tenu de leur poids et de leur volume, ces ensembles doivent être grutés. Cette opération de grutage complique grandement l'installation puisque l'utilisation d'une grue en milieu urbain impose des préalables et des mesures de sécurité contraignantes. Furthermore, depending on the area of implantation and the coverage to be achieved, that is to say the extent of the geographical area in which it is desired to be able to transmit from the antennas of the implanted device, the antennas may have different dimensions and in fact different weights. It is in particular known panel antennas, having a parallelepiped shape, which are fixed on the support to be arranged vertically in the operational configuration of emission antennas. It is understood that the possibility of having antennas of different dimensions from one application to another implies for the antenna support manufacturer to propose a large number of supports able to respectively allow the attachment of antennas of a certain type. These antennas form voluminous and heavy sets, which especially in urban areas are difficult to install. Indeed, the installation of this type of set often occurs at the top of a building or building. Given their weight and volume, these sets need to be grilled. This crane operation greatly complicates the installation since the use of a crane in an urban environment imposes prerequisites and restrictive safety measures.
A titre d'exemple, l'utilisation de certaines grues requiert l'obtention d'autorisation publique ou privé et il peut être nécessaire, parfois, de dévier la circulation urbaine. On comprend donc que ces préalables imposent une organisation compliquée à mettre en œuvre qui a un impact sur la planification et donc le budget du chantier. De même, l'utilisation de ces grues nécessite la mise en place de dispositif de sécurité pour protéger les biens et les personnes situés autour du lieu d'installation. Ces dispositifs de sécurité sont coûteux et long à mettre en place, et finalement cela complique l'organisation lors d'un montage d'un ensemble au sommet d'un bâtiment urbain. For example, the use of some cranes requires obtaining public or private authorization and it may be necessary, sometimes, to divert urban traffic. We understand that these prerequisites impose a complicated organization to implement which has an impact on the planning and therefore the budget of the site. Similarly, the use of these cranes requires the establishment of a safety device to protect the property and people around the place of installation. These safety devices are costly and time consuming to put in place, and ultimately it complicates the organization when mounting a set at the top of an urban building.
La présente invention s'inscrit dans ce contexte et vise à proposer un ensemble formé par un support et par ces antennes associées qui s'inscrivent parfaitement dans le cadre environnemental et qui limitent au maximum les contraintes sur le support.

Dans la description qui va suivre, on va détailler la réalisation d'une portion d'émission d'un ensemble formé d'un support d'antennes et des antennes associées, notamment comprenant une paroi disposée entre deux antennes successives et dont la position est réglable radialement pour s'ajuster d'un ensemble à l'autre selon la taille des antennes à supporter. Tel que cela sera décrit, un tel support d'antennes comporte une première portion configurée pour
être solidarisée à une structure et une deuxième portion apte à recevoir les antennes, et on peut prévoir, selon la zone d'implantation, les contraintes environnementales pour l'émission et/ou l'installation, que ces deux portions du support d'antennes soient distinctement réalisées et assemblées sur site, ou que ces deux portions soient d'un seul tenant. On comprend que le réglage en position radial des parois de la deuxième portion peut être prévu quelle que soit la réalisation des deux portions, et dans le cas où les deux portions sont réalisées distinctement, quel que soit le mode d'assemblage des portions entre elles. On va décrire plus particulièrement un cas où les deux portions sont articulées l'une par rapport à l'autre, étant entendu que le réglage radial de la paroi s'applique selon l'invention quel que soit la conception générale du support d'antennes. In the description which follows, we will detail the realization of a transmission portion of a set formed of an antenna support and associated antennas, including a wall disposed between two successive antennas and whose position is radially adjustable to fit from one set to another depending on the size of antennas to support. As will be described, such an antenna support comprises a first portion configured to be secured to a structure and a second portion adapted to receive the antennas, and it can be provided, depending on the implantation area, the environmental constraints for the emission and / or the installation, that these two portions of the antenna support are distinctly made and assembled on site, or that these two portions are in one piece. It will be understood that the adjustment in the radial position of the walls of the second portion may be provided regardless of the production of the two portions, and in the case where the two portions are made separately, regardless of the method of assembling the portions together. . A case in which the two portions are articulated with respect to each other is more particularly described, it being understood that the radial adjustment of the wall is applicable according to the invention regardless of the general design of the antenna support. .
En se référant tout d'abord à la figure 1 , on voit un support d'antennes 1 , le support étant ici agencé pour recevoir trois antennes 2, régulièrement réparties angulairement autour d'un axe d'allongement général 3 du support d'antennes 1 lorsque celui-ci est dans la position assemblée illustrée sur cette figure 1 , avantageusement verticale. Referring firstly to FIG. 1, we see an antenna support 1, the support being here arranged to receive three antennas 2, regularly distributed angularly around a general elongation axis 3 of the antenna support. 1 when it is in the assembled position illustrated in this Figure 1, preferably vertical.
Le support d'antennes 1 comporte deux portions distinctes, que l'on peut différencier fonctionnellement comme l'une étant une première portion 4, dite de fixation, s'étendant selon une première direction d'allongement 5 (visible notamment sur la figure 6), et l'autre étant une deuxième portion 6, dite d'émission, s'étendant selon une deuxième direction d'allongement 7 (également visible sur la figure 6). The antenna support 1 comprises two distinct portions, which can be differentiated functionally as one being a first portion 4, said fixing, extending in a first elongation direction 5 (visible in particular in Figure 6 ), and the other being a second portion 6, said emission, extending in a second elongation direction 7 (also visible in Figure 6).
Les deux portions 4, 6 distinctes du support d'antennes 1 sont articulées l'une par rapport à l'autre, de sorte qu'elles peuvent par exemple pivoter relativement l'une par rapport à l'autre, autour d'un axe 8 de l'articulation 9 prévue entre les deux portions (notamment visible sur les figures 7 et 10) transversal à l'axe d'allongement général du support d'antennes. On décrira par la suite plus précisément ces moyens d'articulation.
Les deux portions présentent chacune une forme sensiblement cylindrique de révolution autour de leur direction d'allongement propre. Afin de donner un ordre d'idée des efforts nécessaires pour articuler les portions du support d'antennes l'une par rapport à l'autre, on pourra estimer la hauteur de la deuxième portion, d'une face d'extrémité à l'autre le long de la deuxième direction d'allongement 7, à environ 3 mètres, pour un diamètre d'environ 70 centimètres. On comprendra que ces valeurs sont données à titre d'exemple, et que les figures réalisées pour illustrer l'invention ne sont pas forcément à l'échelle. Le diamètre de la première portion 4 est prévu sensiblement égal au diamètre de la deuxième portion 6 pour donner impression d'un tube continu lorsque le support d'antennes 1 est dans sa position assemblée telle qu'illustrée sur la figure 1. The two distinct portions 4, 6 of the antenna support 1 are articulated with respect to each other, so that they can for example pivot relative to one another about an axis 8 of the articulation 9 provided between the two portions (particularly visible in Figures 7 and 10) transverse to the axis of general elongation of the antenna support. Hereinafter will be described more precisely these articulation means. The two portions each have a substantially cylindrical shape of revolution around their own elongation direction. In order to give an idea of the forces required to articulate the portions of the antenna support with respect to each other, it will be possible to estimate the height of the second portion, from an end face to the other along the second direction of elongation 7, about 3 meters, for a diameter of about 70 centimeters. It will be understood that these values are given by way of example, and that the figures made to illustrate the invention are not necessarily to scale. The diameter of the first portion 4 is provided substantially equal to the diameter of the second portion 6 to give impression of a continuous tube when the antenna support 1 is in its assembled position as illustrated in Figure 1.
La première portion 4, dite de fixation est capotée, ici notamment par trois capots 10 articulés aptes à prendre une position de recouvrement dans laquelle les capots 10 forment, lorsqu'ils sont tous dans cette position de recouvrement, un capotage continu sur tout le pourtour de la première portion 4. The first portion 4, said fixing is covered, here in particular by three hinged hoods 10 adapted to take a covering position in which the covers 10 form, when they are all in this covering position, a continuous rollover all around the circumference of the first portion 4.
La deuxième portion 6, dite d'émission, comporte un agencement alterné d'antennes 2, ici des antennes dites panneaux, et de parois 12 de liaison entre les antennes. Une paroi de liaison 12 s'étend entre deux antennes 2 et sa constitution sera décrite plus en détails ci- après. Il importe de noter ici que l'on cherche à proposer une deuxième portion, dite d'émission, donnant l'image d'un ensemble compact. On a dans le mode de réalisation illustré un ensemble dans lequel trois antennes et trois parois sont disposées en alternance les unes par rapport aux autres, les antennes et les parois étant respectivement réparties angulairement à 120°. On comprendra que la répartition angulaire et le nombre d'antennes et de parois peut varier sans sortir du contexte de l'invention. The second portion 6, called transmission, comprises an alternating arrangement of antennas 2, here antennas said panels, and 12 connecting walls between the antennas. A connecting wall 12 extends between two antennas 2 and its constitution will be described in more detail below. It is important to note here that one seeks to propose a second portion, called emission, giving the image of a compact set. In the illustrated embodiment there is an assembly in which three antennas and three walls are arranged alternately with respect to each other, the antennas and the walls being respectively angularly distributed at 120 °. It will be understood that the angular distribution and the number of antennas and walls can vary without departing from the context of the invention.
A son extrémité supérieure 13, c'est-à-dire l'extrémité opposée à la première portion 4, dite de fixation, le support d'antennes 1 comporte une plaque de fermeture 14 sensiblement transversale à l'axe d'allongement général du support d'antennes 1.
Une ceinture annulaire 16 peut être disposée verticalement entre la première portion 4 et la deuxième portion 6, ou bien en recouvrement de la zone de jonction des deux portions, pour assurer l'étanchéité entre les deux portions lorsque celles-ci sont dans une configuration assemblée, c'est-à-dire que le support d'antennes 1 s'étend entièrement selon l'axe général d'allongement. Cette ceinture annulaire 16 peut avantageusement être formée d'au moins deux parties rassemblées l'une contre l'autre pour entourer le support d'antennes, au niveau de l'extrémité supérieure de la première portion 4 et de l'extrémité inférieure de la deuxième portion 6 qui sont toutes deux en regard. La ceinture annulaire 16 a un rôle esthétique et d'étanchéité à la jonction des deux portions du support d'antennes, et elle permet un accès simplifié aux connecteurs situés en partie basse de chacune des antennes 2 du support 1. La ceinture annulaire 16 est notamment visible sur la figure 2, où les antennes ont été retirées et les capots 10 représentés dans une position d'ouverture, pour rendre visible un mât 18 s'étendant à l'intérieur de chacune deux portions 4 et 6. At its upper end 13, that is to say the end opposite the first portion 4, said fixing, the antenna support 1 comprises a closure plate 14 substantially transverse to the axis of general elongation of the antenna support 1. An annular belt 16 may be arranged vertically between the first portion 4 and the second portion 6, or in overlap of the junction zone of the two portions, to seal between the two portions when they are in an assembled configuration that is, the antenna support 1 extends entirely along the general axis of elongation. This annular belt 16 may advantageously be formed of at least two parts joined one against the other to surround the antenna support, at the upper end of the first portion 4 and the lower end of the second portion 6 which are both facing each other. The annular belt 16 has an aesthetic and sealing role at the junction of the two portions of the antenna support, and it allows simplified access to the connectors located in the lower part of each of the antennas 2 of the support 1. The annular belt 16 is in particular visible in Figure 2, where the antennas were removed and the hoods 10 shown in an open position, to make visible a mast 18 extending inside each of two portions 4 and 6.
Les capots 10 sont articulés par des charnières formant un axe de rotation sensiblement parallèle à l'axe d'allongement général du support d'antennes 1 , et ils sont ainsi aptes à prendre une position d'ouverture (visible sur la figure 2) pour laisser accès à un opérateur aux éléments constitutifs de la première portion 4, et notamment les moyens techniques logés dans le compartiment défini par cette première portion, et une position de fermeture (visible sur la figure 1) lorsque le support d'antennes 1 est dans une position opérationnelle d'émission. The covers 10 are articulated by hinges forming an axis of rotation substantially parallel to the general axis of elongation of the antenna support 1, and they are thus able to assume an open position (visible in FIG. allow access to an operator to the constituent elements of the first portion 4, and in particular the technical means housed in the compartment defined by this first portion, and a closed position (visible in Figure 1) when the antenna support 1 is in an operational emission position.
Sur la figure 2, la première portion 4 comprend une armature 20 agencée notamment pour répartir les efforts sur une structure d'accueil (ici non représentée) sur laquelle est fixée la première portion 4. L'armature 20 comporte une embase 22 et une pluralité de montants 24, ici par exemple au nombre de trois, qui s'étendent selon la première direction d'allongement 5 depuis cette embase 22. In FIG. 2, the first portion 4 comprises an armature 20 arranged in particular to distribute the forces on a reception structure (here not shown) on which the first portion 4 is fixed. The armature 20 comprises a base 22 and a plurality of uprights 24, here for example three in number, which extend in the first direction of elongation 5 from this base 22.
L'embase 22 comporte une pluralité de branches 26, ici par exemple au nombre de trois,
s'étendant radialement, dans une disposition en étoile, depuis un socle central 28 jusqu'à un élément de cerclage périphérique 30 qui assure la stabilité de l'ensemble sur la structure d'accueil. On pourra noter qu'avantageusement, les branches 26 sont réparties angulairement de la même manière que les montants 24 de sorte que ces derniers s'étendent depuis le cerclage périphérique 30 dans la continuité des branches 26, pour offrir une bonne reprise d'efforts. The base 22 comprises a plurality of branches 26, here for example three in number, extending radially, in a star arrangement, from a central base 28 to a peripheral strapping element 30 which ensures the stability of the assembly on the receiving structure. It may be noted that advantageously, the branches 26 are angularly distributed in the same manner as the uprights 24 so that the latter extend from the peripheral band 30 in the continuity of the branches 26, to provide a good recovery efforts.
Au niveau du socle central 28 (référence visible sur la figure 7), l'embase 22 est solidaire d'une première partie 32 du mât 18, qui s'étend centré sur la première direction d'allongement 5 de la première portion 4. A l'extrémité distale de cette première partie 32 du mât 18, c'est- à- dire à l'extrémité opposée de l'embase 22, la première partie 32 du mât 18 porte une première platine 34 qui s'étend sensiblement perpendiculairement à la première direction d'allongement. La première platine 34 présente une forme de quadrilatère, ici un carré, sur un côté duquel sont agencées deux éléments de charnière apte à recevoir une tige 35 formant l'axe d'articulation 8 de la deuxième portion 6 par rapport à la première portion 4, la tige 35 s'étendant selon une direction transversale à la direction d'allongement de l'une ou l'autre des portions. At the central base 28 (reference shown in Figure 7), the base 22 is secured to a first portion 32 of the mast 18, which extends centered on the first elongation direction 5 of the first portion 4. At the distal end of this first portion 32 of the mast 18, that is to say at the opposite end of the base 22, the first portion 32 of the mast 18 carries a first plate 34 which extends substantially perpendicularly. at the first direction of elongation. The first plate 34 has a quadrilateral shape, here a square, on one side of which are arranged two hinge elements adapted to receive a rod 35 forming the hinge axis 8 of the second portion 6 relative to the first portion 4 , the rod 35 extending in a direction transverse to the direction of elongation of one or other of the portions.
La première partie 32 du mât s'étend entre les montants 24 et des premiers bras de fixation 36 s'étendent transversalement à la première direction d'allongement 5 de la première portion pour relier les montants à cette première partie du mât et rigidifier l'ensemble de l'armature. The first part 32 of the mast extends between the uprights 24 and first attachment arms 36 extend transversely to the first elongation direction 5 of the first portion to connect the uprights to this first part of the mast and stiffen the set of frame.
La deuxième portion 6 du support d'antennes 1 s'étend autour d'une deuxième partie 38 du mât 18, qui est montée articulée par rapport à la première partie 32 du mât, au moyen de l'articulation 9. A cet effet, la deuxième partie 38 du mât présente à l'une de ses extrémités, celle amenée à être au voisinage de la première partie 32 du mât, une deuxième platine 40 qui s'étend sensiblement perpendiculairement à la deuxième direction d'allongement 7. La deuxième platine 40 présente une forme de quadrilatère, ici un carré, sur un côté duquel sont agencées au moins un élément de charnière apte à recevoir la tige 35 formant une articulation de la deuxième portion 6 par rapport à la première portion 4. L'élément de charnière ménagé sur la deuxième platine 40 est par exemple reçu entre les deux éléments de charnière de la première platine 34.
La première platine 34, la deuxième platine 40, et la tige 35 forment l'articulation 9 au sens de l'invention. On comprend que lorsque le support d'antennes 1 est dans sa configuration opérationnelle d'émission, c'est-à-dire avec une première portion 4 et une deuxième portion 6 qui s'étendent verticalement dans la continuité l'une de l'autre, l'articulation est dans un état tel que les deux platines 34, 40 sont plaquées l'une contre l'autre, de sorte que le mât 18 s'étend de façon rectiligne sur toute la hauteur formée par la première partie 32 de mât 18 et la deuxième partie 38 de mât 18. The second portion 6 of the antenna support 1 extends around a second portion 38 of the mast 18, which is articulated relative to the first portion 32 of the mast, by means of the hinge 9. For this purpose, the second portion 38 of the mast has at one of its ends, that brought to be in the vicinity of the first portion 32 of the mast, a second plate 40 which extends substantially perpendicular to the second direction of elongation 7. The second platen 40 has a quadrilateral shape, here a square, on one side of which are arranged at least one hinge element adapted to receive the rod 35 forming an articulation of the second portion 6 relative to the first portion 4. The element hinge formed on the second plate 40 is for example received between the two hinge elements of the first plate 34. The first plate 34, the second plate 40, and the rod 35 form the hinge 9 within the meaning of the invention. It is understood that when the antenna support 1 is in its operational transmission configuration, that is to say with a first portion 4 and a second portion 6 which extend vertically in continuity one of the other, the articulation is in a state such that the two plates 34, 40 are pressed against each other, so that the mast 18 extends rectilinearly over the entire height formed by the first part 32 of mast 18 and the second part 38 of mast 18.
Lorsque le support d'antennes 1 est en configuration opérationnelle, on prévoit des seconds bras de fixation 42, ici trois, agencés entre les montants 24 de la première portion 4 et la deuxième partie 38 du mât 18, pour rigidifier l'ensemble. On comprend que contrairement aux premiers bras de fixation 36 qui restent immobiles entre les montants 24 fixes et la première partie 32 du mât 18 fixe, les seconds bras de fixation 42, qui relient, en configuration opérationnelle, les montants 24 restés fixes et la deuxième partie 38 du mât 18 qui, elle, pivote pour passer d'une configuration de montage à cette configuration opérationnelle, doivent suivre cette deuxième partie ou bien rester à demeure sur les montants. When the antenna support 1 is in operational configuration, there are provided second attachment arms 42, here three, arranged between the uprights 24 of the first portion 4 and the second portion 38 of the mast 18, to stiffen the assembly. It is understood that unlike the first attachment arms 36 which remain stationary between the fixed uprights 24 and the first portion 32 of the fixed mast 18, the second attachment arms 42, which connect, in operational configuration, the uprights 24 remained fixed and the second part 38 of the mast 18 which, it pivots to pass from a mounting configuration to this operational configuration, must follow this second part or remain permanently on the amounts.
Les seconds bras de fixation 42 sont solidaires de la deuxième partie 38 du mât 18 de manière à suivre le déplacement en pivotement, et ils présentent avantageusement une forme de fourche 44 à leur extrémité libre opposée au mât 18 pour venir s'engager autour du montant correspondant 24 et pouvoir être boulonné au montant. The second attachment arms 42 are secured to the second portion 38 of the mast 18 so as to follow the pivotal movement, and they advantageously have a fork shape 44 at their free end opposite the mast 18 to engage around the upright corresponding 24 and can be bolted to the amount.
Au moins une liaison entre un second bras de fixation 42 et un montant 24 comprend un moyen autorisant un pivotement du second bras vis-à-vis du montant sur lequel il est fixé. En d'autres termes, on peut distinguer parmi ces seconds bras de fixation un bras de fixation principal qui s'étend à l'opposé du sens de basculement par rapport à la deuxième partie 38 du mât 18, c'est-à-dire de l'autre côté du mat par rapport à l'articulation des deux portions, et deux bras de fixation ajustables, disposés ici sensiblement à 120° du bras de fixation principal. La fourche du bras de fixation principal s'engage naturellement autour du montant correspondant
et peut être boulonnée directement sur le montant. Les bras de fixation ajustables présentent une fourche 44 particulière en ce que l'une des ailes 46 de cette fourche est pivotable pour être, dans un premier état, rabattue contre une paroi du montant lorsque l'aile opposée de la fourche est plaquée autour du montant correspondant dans la configuration d'émission, et pour être, dans un deuxième état, escamotée et ne pas gêner le pivotement de la deuxième portion 6. On comprend que l'aile 46 escamotable est l'aile de la fourche tournée à l'opposé du sens de basculement. At least one connection between a second attachment arm 42 and an upright 24 comprises means allowing a pivoting of the second arm vis-à-vis the amount to which it is attached. In other words, one can distinguish among these second fixing arms a main fixing arm which extends opposite the direction of tilting relative to the second portion 38 of the mast 18, that is to say on the other side of the mat relative to the articulation of the two portions, and two adjustable attachment arms, disposed here substantially at 120 ° of the main fixing arm. The fork of the main attachment arm engages naturally around the corresponding amount and can be bolted directly to the stud. The adjustable attachment arms have a particular fork 44 in that one of the wings 46 of this fork is pivotable to be, in a first state, folded against a wall of the upright when the opposite wing of the fork is pressed around the corresponding amount in the transmission configuration, and to be, in a second state, retracted and do not interfere with the pivoting of the second portion 6. It is understood that the retractable wing 46 is the wing of the fork turned to the opposite of the tilt direction.
On forme ainsi, par la présence de ces bras de fixation 38, 42, des montants 24 et de l'embase 22 apte à être solidarisée à une structure d'accueil, un dispositif de reprise d'efforts 47 entre la première portion 4 et la deuxième portion 6, le dispositif de reprise d'efforts s'étendant au moins entre l'armature de la première portion 4 et la deuxième partie 38 du mât 18 de la deuxième portion 6. On peut se référer à la vue en coupe de la figure 3 pour continuer à décrire cette deuxième portion 6. Tel que précisé précédemment, cette deuxième portion 6, dite d'émission, comporte un agencement alterné d'antennes 2 et de parois 12 de liaison entre les antennes. Une pluralité d'antennes 2 est agencée parallèlement à la deuxième direction d'allongement de la deuxième portion ces antennes étant régulièrement réparties angulairement autour de l'axe de révolution de la deuxième portion 6 et espacées de manière à pouvoir loger entre deux antennes 2 successives une paroi de liaison 12. La conformation des antennes et des parois de liaison et leur agencement alterné permettent de délimiter un périmètre fermé de la deuxième portion 6 du support d'antennes, qui présente en section un profil sensiblement circulaire. Les antennes 2 sont des antennes panneaux, qui consistent en des blocs s'étendant sur sensiblement toute la hauteur de la deuxième portion 6 et présentant une section sensiblement rectangulaire, la hauteur de la deuxième portion 6 étant définie comme la dimension s'étendant le long de la deuxième direction d'allongement 7 de la deuxième partie 38 du mât 18. Chaque antenne 2 présente une face avant 48 ou face extérieure, car tournée vers l'extérieur du support
d'antennes, et faisant notamment office de face d'émission, une face arrière 50 opposée et faisant notamment office de face de fixation au mât 18, et deux faces latérales 52. Les antennes sont fixées à la deuxième partie 38 du mât 18 par l'intermédiaire de plaques de fixation 54, 56 rendues solidaires du mât et qui forment un dispositif d'accrochage sur lequel les antennes 2 sont rapportées et accrochées, notamment par boulonnage. Il est intéressant de prévoir que les plaques de fixation hautes 54, qui permettent l'accrochage des antennes au voisinage de l'extrémité supérieure 13 du support d'antennes 1, sont montées articulées sur le mât pour faciliter la mise en place de l'antenne 2, et opérer différents réglages de position des antennes 2, notamment un réglage indépendant en azimut de chaque antenne. Thus, by the presence of these attachment arms 38, 42, the uprights 24 and the base 22 adapted to be secured to a receiving structure are formed, a force-taking device 47 between the first portion 4 and the second portion 6, the force recovery device extending at least between the armature of the first portion 4 and the second portion 38 of the mast 18 of the second portion 6. Reference can be made to the sectional view of Figure 3 to continue to describe this second portion 6. As previously stated, this second portion 6, called emission, comprises an alternating arrangement of antennas 2 and 12 connecting walls between the antennas. A plurality of antennas 2 is arranged parallel to the second direction of elongation of the second portion, these antennas being regularly angularly distributed around the axis of revolution of the second portion 6 and spaced so as to be able to fit between two successive antennas 2 a connecting wall 12. The conformation of the antennas and the connecting walls and their alternating arrangement allow delimiting a closed perimeter of the second portion 6 of the antenna support, which has a substantially circular profile in section. The antennas 2 are panel antennas, which consist of blocks extending over substantially the entire height of the second portion 6 and having a substantially rectangular section, the height of the second portion 6 being defined as the dimension extending along the second elongation direction 7 of the second portion 38 of the mast 18. Each antenna 2 has a front face 48 or outer face, as turned towards the outside of the support of antennas, and in particular acting as an emission face, an opposite rear face 50 and in particular serving as fixing face to the mast 18, and two lateral faces 52. The antennas are fixed to the second part 38 of the mast 18 by by means of fixing plates 54, 56 made integral with the mast and which form an attachment device on which the antennas 2 are attached and hooked, in particular by bolting. It is advantageous to provide that the high fixing plates 54, which allow the antennas to be hooked in the vicinity of the upper end 13 of the antenna support 1, are mounted articulated on the mast to facilitate the installation of the antenna. antenna 2, and operate different position settings of the antennas 2, including an independent azimuth adjustment of each antenna.
Sur les figures 14 à 16, on a illustré trois antennes panneaux de dimensions différentes, en largeur 11, 12, 13 et/ou en épaisseur el, e2, e3. On comprend que le support d'antennes selon l'invention permet une utilisation quel que soit le type d'antennes utilisé. A cet effet, la deuxième portion 6 du support 1 d'antennes prévoit de disposer des parois de liaison 12 dont la position radiale est réglable par rapport à la deuxième partie 38 du mât 18. In FIGS. 14 to 16, three panel antennas of different dimensions, in width 11, 12, 13 and / or in thickness e1, e2, e3, are illustrated. It is understood that the antenna support according to the invention allows use regardless of the type of antenna used. For this purpose, the second portion 6 of the antenna support 1 provides for connecting walls 12 whose radial position is adjustable relative to the second portion 38 of the mast 18.
Les parois de liaison 12 sont disposées entre les antennes 2 de manière à alterner une antenne 2 et une paroi de liaison 12 sur le pourtour de la deuxième portion 6 du support d'antennes 1. On peut notamment se référer à la figure 11, et aux figures 8 à 10, pour la description des parois qui va suivre. Chaque paroi de liaison 12 comporte une portion centrale rigide 58, par exemple en résine, dont la face extérieure est tournée vers l'extérieur du support d'antennes 1 en présentant une section, dans un plan perpendiculaire au mât, sensiblement courbe, afin d'épouser un profil circulaire du deuxième support centré sur la deuxième partie 38 du mât 18. La portion centrale rigide 58 est prolongée latéralement par deux lèvres élastiquement déformables 60, de type lèvre en caoutchouc, disposées de part et d'autre de cette portion centrale 58. Les lèvres 60 sont des bandes souples s'étendant sensiblement sur toute la hauteur de la paroi de liaison 12. Le joint à lèvres ainsi formé par chacune des bandes peut être fixé par collage sur une extrémité latérale du panneau correspondant formé par la portion centrale rigide. Tel qu'illustré sur la ue de détail en coupe de la figure 1 1b, une extrémité latérale
d'une lèvre 60 peut être logée dans une gorge 61 formée latéralement sur la portion centrale rigide 58, partiellement ou sur toute la hauteur de celle-ci, afin d'y être collée par exemple. The connecting walls 12 are arranged between the antennas 2 so as to alternate an antenna 2 and a connecting wall 12 on the periphery of the second portion 6 of the antenna support 1. In particular, reference may be made to FIG. Figures 8 to 10 for the description of the walls that follow. Each connecting wall 12 comprises a rigid central portion 58, for example made of resin, whose outer face is turned towards the outside of the antenna support 1 by having a section, in a plane perpendicular to the mast, substantially curved, in order to marry a circular profile of the second support centered on the second portion 38 of the mast 18. The rigid central portion 58 is extended laterally by two elastically deformable lips 60, of the rubber lip type, arranged on either side of this central portion 58. The lips 60 are flexible bands extending substantially over the entire height of the connecting wall 12. The lip seal thus formed by each of the strips may be fixed by gluing on a lateral end of the corresponding panel formed by the portion rigid central. As illustrated in the sectional detail of FIG. 1 1b, a lateral end a lip 60 may be housed in a groove 61 formed laterally on the rigid central portion 58, partially or over the entire height thereof, in order to be glued there for example.
Les lèvres élastiquement déformables 60 sont conformées pour présenter à leur extrémité libre, c'est-à-dire l'extrémité opposée à la portion centrale 58 de la paroi de liaison 12, une forme courbée en section vers l'intérieur du support d'antennes 1 , lorsque la paroi de liaison 12 correspondante est montée sur le support d'antennes 1 , pour former une boucle 62. Lorsqu'une paroi de liaison 12 est montée entre deux antennes 2, une boucle 62 de la lèvre élastiquement déformable 60 située d'un côté de la paroi de liaison 12 est en appui contre la face latérale 52 de l'antenne 2 disposée de ce côté de la paroi. Ce contact forme un moyen d'étanchéité du support d'antennes 1 , évitant une intrusion de saletés et d'eau de pluie notamment, et évitant également la prise au vent du support d'antennes 1. Pour illustrer ce contact entre l'antenne 2 et la lèvre 60 de la paroi de liaison 12, on a représenté en figures 12 et 13 deux exemples de réalisation d'un support d'antennes avec des antennes de tailles différentes. Dans chacun de ces cas, la boucle 62 est en appui sur la face latérale 52 correspondante, plus ou moins déformée selon la distance existante entre l'extrémité latérale de la paroi de liaison 12 et la face latérale de l'antenne. Dans ce contexte d'adaptabilité du support d'antennes à différentes dimensions d'antennes, le support selon l'invention prévoit des moyens de réglage 63 de la position radiale des parois de liaison 12. Ainsi, il est clair que dans le cas illustré sur la figure 12, le profil de la face extérieure des parois de liaison, lorsqu'elles sont en position opérationnelle contre les antennes voisines (sur la figure 12, une paroi a été représentée en position de retrait par rapport à la position assemblée dans laquelle sont représentées les deux autres parois de liaison) s'étend à une distance RI inférieure à la distance R2 à laquelle s'étend la face extérieure des parois de liaison dans le cas illustré sur la figure 13 où les antennes supportées sont de plus grandes dimensions que celles des antennes supportées dans le cas illustré sur la figure 12. The elastically deformable lips 60 are shaped to have at their free end, that is to say the end opposite to the central portion 58 of the connecting wall 12, a curved shape in section towards the inside of the support of antennas 1, when the corresponding connecting wall 12 is mounted on the antenna support 1, to form a loop 62. When a connecting wall 12 is mounted between two antennas 2, a loop 62 of the elastically deformable lip 60 located on one side of the connecting wall 12 bears against the lateral face 52 of the antenna 2 disposed on this side of the wall. This contact forms a means of sealing the antenna support 1, avoiding an intrusion of dirt and rainwater in particular, and also avoiding taking wind antenna 1 support. To illustrate this contact between the antenna 2 and the lip 60 of the connecting wall 12, there is shown in Figures 12 and 13 two embodiments of an antenna support with antennas of different sizes. In each of these cases, the loop 62 bears on the corresponding lateral face 52, more or less deformed according to the distance existing between the lateral end of the connecting wall 12 and the lateral face of the antenna. In this context of adaptability of the antenna support to different antenna dimensions, the support according to the invention provides adjustment means 63 for the radial position of the connecting walls 12. Thus, it is clear that in the illustrated case in Figure 12, the profile of the outer face of the connecting walls, when in operative position against neighboring antennas (in Figure 12, a wall has been shown in the retracted position with respect to the assembled position in which are represented the two other connecting walls) extends at a distance RI less than the distance R2 to which extends the outer face of the connecting walls in the case illustrated in Figure 13 where the supported antennas are larger than those of the antennas supported in the case illustrated in FIG. 12.
La paroi de liaison 12 est fixée sur la deuxième partie 38 du mât 18 par l'intermédiaire d'une pluralité de barres 64 s'étendant sensiblement perpendiculairement au mât 18 et fixées respectivement à leur extrémité libre sur la face arrière de la portion centrale rigide 58. Dans un
mode de réalisation particulier de l'invention, la paroi de liaison 12 est fixée sur la deuxième partie 38 du mât 18 par l'intermédiaire de moyens réglables pour contrôler l'écartement radial de la paroi de liaison 12. Les barres 64 sont fixées sur la face arrière de la paroi de liaison 12 de manière à la prolonger sensiblement perpendiculairement, et elles sont disposées respectivement dans un fourreau formant logement 66 solidaire du mât. La fixation des barres 64 sur la paroi de liaison se fait par l'intermédiaire d'une plaquette 64b s'étendant sensiblement perpendiculairement à l'extrémité libre de la barre 64, c'est-à-dire à l'extrémité opposée de l'extrémité configurée pour coulisser à l'intérieur du logement 66. Cette plaquette 64b peut présenter une forme incurvée pour épouser le profil de la face intérieure de la paroi de liaison contre laquelle elle vient être plaquée. The connecting wall 12 is fixed on the second portion 38 of the mast 18 via a plurality of bars 64 extending substantially perpendicularly to the mast 18 and respectively fixed at their free end to the rear face of the rigid central portion 58. In a particular embodiment of the invention, the connecting wall 12 is fixed on the second portion 38 of the mast 18 by means of adjustable means for controlling the radial spacing of the connecting wall 12. The bars 64 are fixed on the rear face of the connecting wall 12 so as to extend substantially perpendicularly, and they are respectively disposed in a housing sleeve 66 integral with the mast. Fixing the bars 64 on the connecting wall is via a wafer 64b extending substantially perpendicularly to the free end of the bar 64, that is to say at the opposite end of the end configured to slide within the housing 66. This wafer 64b may have a curved shape to match the profile of the inner face of the connecting wall against which it has been plated.
Chaque barre et chaque fourreau présentent une pluralité d'orifices 65 (notamment visibles sur la figure l ia) disposés respectivement le long de la barre et du fourreau dans la direction de réglage radial de la paroi par rapport au mât, que l'opérateur peut faire correspondre les uns en face des autres pour augmenter la distance séparant le mât 18 et la paroi de liaison 12. Lorsque l'utilisateur a positionné à la distance souhaitée la barre 64, des moyens de fixation, par exemple par boulonnage, ici non représentés, sont insérés à travers les orifices 65 en regard pour fixer cette position. Les orifices et les moyens de boulonnage forment un dispositif de blocage de la barre dans le logement dans au moins deux positions déterminées. On comprend que par pluralités d'orifices 65 sur les tubes et les logements, on entend qu'au moins un parmi le tube et le logement correspondant comprend une série radiale d'orifice, l'autre parmi le tube et le logement pouvant ne comprendre qu'un seul orifice que l'on aligne avec l'orifice souhaité pour obtenir le bon réglage en position radiale. Tel que cela a été précisé précédemment, on comprend que ce moyen de réglage radial 63 permet de positionner plus ou moins à distance du mât 18 les parois de liaison 12 et les boucles 62 des lèvres élastiques déformables 60 associées, et donc de s'adapter à des antennes de largeurs différentes d'un mât à l'autre en s'assurant que les boucles 62 reposent bien sur les faces latérales 52 des antennes 2. Un même mat 18 et de mêmes parois de liaison 12 peuvent être utilisés pour étanchéifier une deuxième portion 6 utilisant des antennes 2 de largeurs différentes. Ceci contribue à standardiser les composants du support
d'antennes et ainsi d'en maintenir le coût aussi bas que possible. Each bar and each sheath have a plurality of orifices 65 (in particular visible in FIG. 11a) respectively disposed along the bar and the sleeve in the direction of radial adjustment of the wall relative to the mast, which the operator can correspond to each other to increase the distance between the mast 18 and the connecting wall 12. When the user has positioned at the desired distance the bar 64, fixing means, for example by bolting, here not shown are inserted through the orifices 65 opposite to fix this position. The orifices and the bolting means form a device for locking the bar in the housing in at least two predetermined positions. It is understood that by pluralities of orifices 65 on the tubes and housings, it is meant that at least one of the tube and the corresponding housing comprises a radial series of orifice, the other of the tube and the housing may not include only one orifice that is aligned with the desired orifice to obtain the correct adjustment in radial position. As has been explained above, it is understood that this radial adjustment means 63 makes it possible to position the connecting walls 12 and the loops 62 of the deformable elastic lips 60 more or less at a distance from the mast 18, and therefore to adapt to antennas of different widths from one mast to another, ensuring that the loops 62 rest on the lateral faces 52 of the antennas 2. The same mat 18 and the same connecting walls 12 can be used to seal a second portion 6 using antennas 2 of different widths. This helps to standardize the support components antennas and thus keep the cost as low as possible.
Tel qu'illustré, et notamment sur la figure l ia, l'extrémité libre 67 de la deuxième partie 38 du mât 18, c'est-à-dire l'extrémité opposée à la platine d'articulation avec la première partie 32 du mât 18, présente une première pièce de fixation 68 qui présente trois fourreaux 66, par exemple de section sensiblement carrée, et dans lesquels on peut respectivement disposer une barre 64 de section équivalente à celle des fourreaux et de dimension légèrement inférieure pour pouvoir plus ou moins éloigner la barre du centre du support d'antenne 1 par un agencement télescopique de la barre dans le fourreau. On comprendra que la section de chaque fourreau, fermée, peut être obtenue indifféremment par la fermeture d'une pièce en U par la pièce de fixation venant en recouvrement, ou par un fourreau formé d'une seule pièce. La coopération de la barre 64 dans le fourreau 66, et le dispositif de blocage associé, forment un moyen de réglage radial 63. L'extrémité inférieure de la deuxième partie du mât, opposée à l'extrémité libre, présente également des moyens de réglage de la position radiale des parois tel que décrit précédemment. Il peut être intéressant que ces moyens de réglage au niveau de l'extrémité inférieure diffère de la forme de fourreau plein de l'extrémité libre, en ce que les moyens de réglage prennent la forme de réceptacles 70, également configurés pour coopérer avec des barres cette fois portées à l'extrémité inférieure correspondante des parois de liaison 12 et permettre la fixation par boulonnage lorsque la position radiale adéquate est trouvée, mais présentant une section en forme de U ouvert vers l'extrémité libre opposée. Chaque réceptacle présente ainsi une section en U avec une base tournée vers la première portion 4 du support d'antennes et deux parois latérales 71 parallèles entre elles et formant moyen de tenue latérale de la barre 64 lorsque celle-ci est engagée dans le logement. Ainsi, on réalise la fonction de réglage radial, les réceptacles comportant sur leurs parois latérales 71 des orifices 65 pour recevoir des moyens de boulonnage, tout en s'autorisant un jeu de positionnement axial, c'est-à-dire dans la direction d'allongement du mât, de premiers moyens de réglage 63a en partie haute du mât et de deuxièmes moyens de réglage 63b en partie basse du mât. On comprend par premiers moyens de réglage en partie haute et deuxièmes moyens de réglage en partie basse les fourreaux et barres associées à l'extrémité libre de la deuxième partie du mat d'une part et les réceptacles et barres associées à
l'extrémité inférieure de la deuxième partie du mat d'autre part. Les orifices 65 formés dans les parois latérales des réceptacles 70 présenteront avantageusement une forme oblongue, avec le grand axe sensiblement parallèle à la direction d'allongement du mât, pour permettre un jeu de montage entre la paroi de liaison et le mât. As illustrated, and in particular in FIG. 11a, the free end 67 of the second part 38 of the mast 18, that is to say the end opposite the articulation plate with the first part 32 of the mast 18, has a first fastener 68 which has three sleeves 66, for example of substantially square section, and in which a bar 64 of equivalent section to that of the sleeves and slightly smaller in size can be respectively disposed for more or less power move the bar from the center of the antenna support 1 by a telescopic arrangement of the bar in the sleeve. It will be understood that the section of each sheath, closed, can be obtained indifferently by the closure of a U-shaped piece by the fixing piece coming in overlap, or by a sleeve formed in one piece. The cooperation of the bar 64 in the sheath 66, and the associated locking device, form a radial adjustment means 63. The lower end of the second portion of the mast, opposite the free end, also has adjustment means. the radial position of the walls as described above. It may be interesting that these means of adjustment at the lower end differs from the shape of the full sleeve of the free end, in that the adjustment means take the form of receptacles 70, also configured to cooperate with bars this time brought to the corresponding lower end of the connecting walls 12 and allow fixing by bolting when the adequate radial position is found, but having a U-shaped section open towards the opposite free end. Each receptacle thus has a U-shaped section with a base facing the first portion 4 of the antenna support and two side walls 71 parallel to each other and forming lateral holding means of the bar 64 when the latter is engaged in the housing. Thus, the radial adjustment function is carried out, the receptacles having on their lateral walls 71 orifices 65 for receiving bolting means, while allowing an axial positioning clearance, that is to say in the direction of extension of the mast, first adjustment means 63a in the upper part of the mast and second adjustment means 63b in the lower part of the mast. It comprises first adjustment means in the upper part and second adjustment means in the lower part of the sleeves and bars associated with the free end of the second part of the mat on the one hand and the receptacles and bars associated with the lower end of the second part of the mat on the other hand. The orifices 65 formed in the side walls of the receptacles 70 will advantageously have an oblong shape, with the major axis substantially parallel to the direction of elongation of the mast, to allow a mounting clearance between the connecting wall and the mast.
Bien entendu, la position évoquée ci-dessus des fourreaux et des réceptacles d'une part, et des barres d'autre part, peut être inversée, les parois de liaison portant en saillie d'une face interne des éléments femelles formant fourreau et le mât portant des éléments mâles formant barre. Sur les figures 14 à 16, on a illustré trois types d'antennes panneaux, distinctes les unes des autres par leurs dimensions. Le moyen de réglage radial selon l'invention permet à la paroi de liaison de prendre des positions radiales prédéterminées, de sorte que les parties souples 60 formant lèvre d'étanchéité viennent porter, par la boucle 62 réalisée à leur extrémité libre, sur la face latérale d'une antenne. La forme de ces antennes peut varier, notamment leur face avant, selon les configurations d'émission de radiocommunication requises, mais il convient de noter que les faces latérales servent de face d'appui pour les parties souples. Le réglage en position radiale permet d'écarter plus ou moins la paroi de liaison du mât et donc s'assurer que les boucles sont au contact, sans être trop contraintes, de la face latérale de l'antenne. A titre d'exemple, on pourra prévoir : Of course, the position mentioned above of the sleeves and receptacles on the one hand, and bars on the other hand, can be reversed, the connecting walls projecting from an inner face of the female elements forming a sheath and the mast carrying male elements forming bar. In FIGS. 14 to 16, three types of panel antennas, which are distinct from one another by their dimensions, have been illustrated. The radial adjustment means according to the invention allows the connecting wall to take predetermined radial positions, so that the flexible portions 60 forming the sealing lip are carried by the loop 62 made at their free end, on the face. side of an antenna. The shape of these antennas can vary, in particular their front face, according to the required radiocommunication transmission configurations, but it should be noted that the lateral faces serve as support face for the flexible parts. The adjustment in radial position allows to more or less separate the connecting wall of the mast and thus ensure that the loops are in contact, without being too constrained, the side face of the antenna. For example, we can provide:
- un premier cas extrême d'utilisation du support pour un jeu d'antennes, dont la largeur a first extreme case of use of the support for a set of antennas whose width
13 peut être à titre d'exemple de 600 millimètres pour une épaisseur e3 de 200 millimètres (figure 16), la position radiale prédéterminée des parois de liaison étant alors la plus éloignée possible du mât (figure 13) ; 13 may be an example of 600 millimeters for a thickness e3 of 200 millimeters (Figure 16), the predetermined radial position of the connecting walls being then the furthest possible from the mast (Figure 13);
- un deuxième cas extrême d'utilisation du support pour un jeu d'antennes, dont la largeur 11 peut être à titre d'exemple de 300 millimètres pour une épaisseur el de 140 millimètres (figure a second extreme case of use of the support for a set of antennas, the width 11 of which may be an example of 300 millimeters for a thickness el of 140 millimeters (FIG.
14), la position radiale prédéterminée des parois de liaison étant alors la plus proche possible du mât (figure 12) ; 14), the predetermined radial position of the connecting walls then being as close as possible to the mast (FIG. 12);
- un ou plusieurs cas intermédiaires d'utilisation, rendus possible dans ce cas par le nombre d'orifices 65 agencés le long de la barre et/ou du logement dans le moyen de réglage radial 63,
pour des jeux d'antennes dont les dimensions sont comprises entre les cas extrêmes donnés ci- dessus, et par exemple une largeur 12 de 400 millimètres pour une épaisseur e2 de 150 millimètres (figure 15). A titre d'exemple, on peut ainsi prévoir que le périmètre fermé du support d'antennes, formé par l'alternance d'antennes et de parois de liaison, s'inscrit dans un diamètre compris entre 550 mm et 800mm, avantageusement compris entre 600mm et 725mm. one or more intermediate cases of use, made possible in this case by the number of orifices 65 arranged along the bar and / or the housing in the radial adjustment means 63, for sets of antennas whose dimensions are between the extreme cases given above, and for example a width 12 of 400 millimeters for a thickness e2 of 150 millimeters (FIG. 15). By way of example, it is thus possible to provide that the closed perimeter of the antenna support, formed by the alternation of antennas and connecting walls, is in a diameter of between 550 mm and 800 mm, advantageously between 600mm and 725mm.
Sur les figures 4 à 7, on a illustré le support d'antennes 1 dans quatre positions successives rendues possibles par l'articulation de la première portion 4 par rapport à la deuxième portion 6, entre deux positions extrêmes. Une première position extrême (figure 4), dite position d'émission et dans laquelle les deux portions 4, 6 sont alignées de sorte que leurs directions d'allongement sont confondues, correspond à une configuration opérationnelle d'émission. Une deuxième position extrême (figure 7), dite position de montage et dans laquelle la deuxième portion 6 est transversale, et sensiblement perpendiculaire, à la première portion 4, correspond à une configuration de montage. On comprend que l'on passe de l'une à l'autre par le pivotement de la deuxième portion 6 mobile par rapport à la première portion 4 fixe, dans la direction de basculement B visible sur les figures 4 à 7, autour de la tige 35 constitutive de l'articulation 9 . Les figures 5 et 6 illustrent des positions intermédiaires entre les deux positions extrêmes décrites ci-dessus, dans lesquelles la deuxième direction d'allongement 7 de la deuxième portion 6 est inclinée par rapport à la première direction d'allongement 5 de la première portion. Figures 4 to 7, there is illustrated the antenna support 1 in four successive positions made possible by the articulation of the first portion 4 relative to the second portion 6, between two extreme positions. A first extreme position (FIG. 4), said emission position, in which the two portions 4, 6 are aligned so that their elongation directions coincide, corresponds to an operational emission configuration. A second extreme position (Figure 7), said mounting position and wherein the second portion 6 is transverse, and substantially perpendicular to the first portion 4, corresponds to a mounting configuration. It is understood that one passes from one to the other by the pivoting of the second movable portion 6 relative to the first fixed portion 4, in the tilting direction B visible in Figures 4 to 7, around the rod 35 constituting the joint 9. Figures 5 and 6 illustrate intermediate positions between the two extreme positions described above, wherein the second elongation direction 7 of the second portion 6 is inclined relative to the first elongation direction 5 of the first portion.
Un moyen d'actionnement 72, notamment hydraulique, est associé au support d'antennes 1 pour faciliter le passage de la deuxième portion d'une position à l'autre, et pour retenir cette deuxième portion contre l'effet de gravité, aussi bien pour la maintenir dans la position extrême de la configuration de montage que pour la maintenir dans des positions intermédiaires stables. Dans l'exemple de réalisation illustré, le moyen d'actionnement 72 est logé principalement à l'intérieur de la première portion 4 du support d'antennes 1 , en étant accessible lorsque les capots 10 sont ouverts. Ce moyen d'actionnement 72 consiste par exemple en un vérin comportant un
piston, prolongé d'une tige 74 et apte à coulisser à l'intérieur d'un cylindre 76 sous l'effet d'une alimentation hydraulique ici non représentée. On comprend qu'une pompe formant des moyens d'alimentation hydraulique pourra être rapportée près de la première portion 4 et raccordée aux orifices d'alimentation du cylindre pour qu'un opérateur puisse réaliser la manœuvre de pivotement ou d'élévation de la deuxième portion 6 du support d'antennes 1, ou bien que des moyens d'asservissement du vérin pourront être intégrés dans le support d'antennes 1 pour piloter à la demande de l'opérateur la pression hydraulique dans les chambres du vérin, et ainsi la position correspondante de la deuxième portion 6 en pivotement par rapport à la première portion 4. An actuating means 72, particularly hydraulic, is associated with the antenna support 1 to facilitate the passage of the second portion from one position to the other, and to retain this second portion against the effect of gravity, as well to maintain it in the extreme position of the mounting configuration only to maintain it in stable intermediate positions. In the exemplary embodiment illustrated, the actuating means 72 is housed mainly inside the first portion 4 of the antenna support 1, being accessible when the covers 10 are open. This actuating means 72 consists for example of a jack comprising a piston, extended by a rod 74 and able to slide inside a cylinder 76 under the effect of a hydraulic supply here not shown. It is understood that a pump forming hydraulic supply means may be reported near the first portion 4 and connected to the supply ports of the cylinder so that an operator can perform the pivoting maneuver or elevation of the second portion 6 of the antenna support 1, or that servo-control means of the cylinder can be integrated in the antenna support 1 to control at the request of the operator the hydraulic pressure in the cylinder chambers, and thus the position corresponding portion of the second portion 6 pivotally relative to the first portion 4.
Avantageusement, le moyen d'actionnement 72 est un vérin hydraulique à double effet. L'utilisation d'un vérin à double effet, et qui plus est hydraulique, permet d'assurer une position stable du piston dans le corps de cylindre sans mouvement oscillant autour de la position souhaitée, ce qui est ici particulièrement important du fait du poids et de la taille de la deuxième portion 6 à articuler par rapport à la première portion 4. Advantageously, the actuating means 72 is a double-acting hydraulic cylinder. The use of a double-acting cylinder, which is more hydraulic, ensures a stable position of the piston in the cylinder body without oscillating movement around the desired position, which is particularly important here because of the weight and the size of the second portion 6 to be articulated with respect to the first portion 4.
La deuxième partie 38 du mât 18, associée à la deuxième portion 6, comporte, au voisinage de son extrémité inférieure, un élément, à savoir ici une première chape 77, apte à recevoir l'extrémité libre de la tige 74, notamment par l'intermédiaire d'un premier axe 78 libre en rotation dans des paliers de cette première chape. La première partie 32 du mât 18 comprend le même type d'élément, à savoir une deuxième chape 80 apte à recevoir l'extrémité du cylindre opposée au piston, également par l'intermédiaire d'un deuxième axe 82 libre en rotation dans des paliers de cette deuxième chape 80. On comprend que, dans le cas d'un vérin alimenté par une pompe manuelle, l'utilisateur réalisera le pivotement de la deuxième portion 6 en activant la pompe, soit en augmentant la pression dans une première chambre du cylindre et en diminuant la pression dans une deuxième chambre du cylindre, de manière à pousser le piston plus avant dans la deuxième chambre et hors du cylindre et en générant de la sorte un pivotement de la configuration de montage vers
la configuration d'émission, soit en diminuant progressivement la pression dans la première chambre et en augmentant la pression dans la première chambre, de manière à aspirer le piston à l'intérieur du cylindre et tirer sur la deuxième partie 38 du mât 18 pour le forcer à pivoter autour de l'axe de l'articulation objet de l'invention. Il est entendu que pour réaliser ces pivotements par l'intermédiaire du moyen d'actionnement 72, la tige 35 de l'articulation 9 pour le pivotement relatif des deux portions 4, 6 du support d'antennes 1 est disposée sur le côté des platines 34, 40 le plus proche du moyen d'actionnement. The second part 38 of the mast 18, associated with the second portion 6, comprises, in the vicinity of its lower end, an element, namely here a first yoke 77, adapted to receive the free end of the rod 74, in particular by means of intermediate of a first axis 78 free in rotation in bearings of this first yoke. The first portion 32 of the mast 18 comprises the same type of element, namely a second yoke 80 adapted to receive the end of the cylinder opposite the piston, also via a second axis 82 free to rotate in bearings of this second clevis 80. It will be understood that, in the case of a cylinder powered by a hand pump, the user will pivot the second portion 6 by activating the pump, or by increasing the pressure in a first chamber of the cylinder and decreasing the pressure in a second chamber of the cylinder, so as to push the piston further into the second chamber and out of the cylinder and thereby generating a pivoting of the mounting configuration to the emission configuration, either by gradually decreasing the pressure in the first chamber and increasing the pressure in the first chamber, so as to suck the piston inside the cylinder and pull on the second part 38 of the mast 18 for the force to pivot about the axis of the hinge object of the invention. It is understood that to achieve these pivoting through the actuating means 72, the rod 35 of the joint 9 for the relative pivoting of the two portions 4, 6 of the antenna support 1 is disposed on the side of the plates 34, 40 closest to the actuating means.
Le moyen d'actionnement 72 a ainsi une double fonction qui est d'une part de permettre la mise en mouvement de la deuxième portion 6 par rapport à la première portion 4, lorsque le montage est effectué et que l'on souhaite que le support d'antennes 1 prenne une configuration d'émission, sensiblement verticale, et d'autre part de retenir la deuxième portion 6 lorsqu'on la fait pivoter pour prendre une position de montage, par exemple pour réaliser le montage initiale des antennes et des composants associés à celles-ci, ou pour réaliser une opération de maintenance sur les antennes 2, alors que cette deuxième portion 6 est entraînée par son poids. The actuating means 72 thus has a dual function which is, on the one hand, to enable the second portion 6 to move with respect to the first portion 4, when the assembly is carried out and that it is desired that the support of antennas 1 takes a transmission configuration, substantially vertical, and secondly to retain the second portion 6 when it is rotated to take a mounting position, for example to achieve the initial assembly of antennas and components associated with them, or to perform a maintenance operation on the antennas 2, while the second portion 6 is driven by its weight.
Tel que cela vient d'être précisé, la première portion 4, outre sa fonction de fixation à la structure d'accueil, permet de loger des équipements annexes parmi lesquels, en plus de la pompe associée au moyen d'actionnement 72 que l'on peut rapporter occasionnellement ou laisser à demeure, l'ensemble des moyens techniques associées à la réception et la diffusion des données de radiocommunications reçues et/ou transmises par les antennes portées par le support d'antennes 1. Tel que cela a été décrit précédemment, le compartiment technique est capoté par des capots 10 articulés. La fermeture des capots permet de disposer d'un compartiment technique étanche abritant les moyens techniques et l'on comprend que l'accessibilité aux moyens technique est facilité lorsque les capots articulés sont ouverts, et le cas échéant maintenus en position ouverte par un système de cale logée en fonctionnement dans le compartiment technique. Par ailleurs, il convient de noter que lorsque les capots sont fermés, la première portion 4 prend la forme d'un compartiment technique à la base du support d'antennes qui présente une enveloppe extérieure de dimensions et de forme égales à l'enveloppe définie par le
pourtour des antennes 2 et des parois de liaison 12 de la deuxième portion 6, de sorte que le support d'antennes présente une forme monobloc cylindrique. As just mentioned, the first portion 4, in addition to its function of attachment to the host structure, can accommodate ancillary equipment among which, in addition to the pump associated with the actuating means 72 that the the technical means associated with the reception and the broadcasting of the radiocommunication data received and / or transmitted by the antennas carried by the antenna support 1 can be occasionally reported or left in abeyance. As previously described the technical compartment is covered by hinged covers 10. Closing hoods provides a sealed technical compartment housing the technical means and it is understood that accessibility to technical means is facilitated when the hinged covers are open, and if necessary kept in the open position by a system of wedge housed in operation in the technical compartment. Furthermore, it should be noted that when the covers are closed, the first portion 4 takes the form of a technical compartment at the base of the antenna support which has an outer envelope of dimensions and shape equal to the envelope defined speak around antennas 2 and connecting walls 12 of the second portion 6, so that the antenna support has a cylindrical one-piece form.
On va maintenant décrire les différentes opérations d'un procédé de montage du support d'antennes. We will now describe the various operations of a mounting method of the antenna support.
Dans un premier temps, un opérateur fixe l'embase 22 de la première portion 4 sur une structure d'accueil prévue préalablement, sur le toit d'un immeuble par exemple. A titre d'exemple, l'embase 22 est boulonnée sur des tiges filetées solidaires de la structure d'accueil. L'embase 22 est fixée avec la première partie 32 du mât 18 solidaire de cette embase et la première platine 34 correspondante. Initially, an operator fixes the base 22 of the first portion 4 on a reception structure previously provided on the roof of a building for example. For example, the base 22 is bolted to threaded rods integral with the receiving structure. The base 22 is fixed with the first portion 32 of the mast 18 secured to this base and the corresponding first plate 34.
Dans un deuxième temps, l'opérateur pose la deuxième partie 38 du mât 18 au sol, en rapprochant la deuxième platine 40, que cette deuxième partie 38 porte à l'une de ses extrémités, de la première platine 34, et en insérant la tige 35 formant l'axe de l'articulation dans les charnières de ces deux platines. L'opérateur installe alors le vérin hydraulique par insertion des premier 78 et deuxième 82 axes dans les chapes 77, 80 correspondantes, et il met en pression le vérin pour soulever la deuxième partie 38 du mât 18 et le maintenir dans un plan tel que l'extrémité libre 67 de la deuxième portion est située au-dessus du plan horizontal passant par l'axe de l'articulation 9. In a second step, the operator places the second part 38 of the mast 18 on the ground, bringing the second plate 40 closer together, that this second part 38 carries at one of its ends, the first plate 34, and inserting the rod 35 forming the axis of the hinge in the hinges of these two plates. The operator then installs the hydraulic cylinder by inserting the first 78 and second 82 axes in the yokes 77, 80 corresponding, and it presses the jack to lift the second portion 38 of the mast 18 and maintain it in a plane such that the free end 67 of the second portion is located above the horizontal plane passing through the axis of the hinge 9.
L'opérateur rapporte par ailleurs sur la première portion 4 d'une part les premiers bras de fixation 36, solidarisés autour de la première partie du mât, et d'autre part les montants 24 sur l'embase 22, avant de les solidariser les uns aux autres. Dans un autre temps, il fixe sur la deuxième partie 38 du mât les plaques de fixation 54,56 qui vont accueillir les antennes 2. The operator also reports on the first portion 4 on the one hand the first attachment arms 36, secured around the first part of the mast, and on the other hand the uprights 24 on the base 22, before joining them together. to each other. In another time, it fixes on the second part 38 of the mast 54.56 fixing plates that will accommodate the antennas 2.
L'opérateur doit alors réaliser le montage des antennes 2 et des parois de liaison 12 sur la deuxième partie 38 du mât 18. Les parois de liaison 12 étant montées par des moyens de fixation réglables radialement, on peut dans un premier temps rapporter les parois de liaison 12 dans une
position radiale la plus éloignée possible du mât 18, puis fixer les antennes 2 sur le mât 18 sans contraindre les lèvres et enfin ajuster la position radiale des parois de liaison 12 pour que les joints à lèvres 60 soient, dans une position radiale de fonctionnement, correctement en appui sur les faces latérales 52 des antennes 2. Cette séquence d'installation, particulièrement avantageuse pour la correcte mise en tension des lèvres sur les antennes et donc la parfaite étanchéité de l'ensemble, peut notamment être comprise au regard de l'illustration de la figure 12, sur laquelle on a représenté une paroi de liaison 12a en position de retrait, semblable à la position radiale la plus éloignée évoquée ci-dessus, et les deux autres parois de liaison dans ladite position radiale de fonctionnement. The operator must then mount the antennas 2 and the connecting walls 12 on the second part 38 of the mast 18. The connecting walls 12 being mounted by means of radially adjustable fastening means, it is possible to relate the walls firstly. link 12 in a radial position as far as possible from the mast 18, then fix the antennas 2 on the mast 18 without constraining the lips and finally adjust the radial position of the connecting walls 12 so that the lip seals 60 are, in a radial operating position, This installation sequence, particularly advantageous for the correct tensioning of the lips on the antennas and thus the perfect sealing of the assembly, can notably be understood with respect to the antenna. FIG. 12 illustrates a connecting wall 12a in a retracted position, similar to the furthest radial position mentioned above, and the other two connecting walls in said radial operating position.
Lorsque chacune des parois de liaison est dans sa position radiale de fonctionnement, l'opérateur a formé un ensemble dont la deuxième portion, en section perpendiculaire à la direction d'allongement du mât, présente un périmètre fermé, régulier sur tout le pourtour. Ceci donne d'une part un aspect esthétique régulier à la portion du support d'antennes destinée à être le plus visible, ce qui facilite son intégration dans un environnement qu'il soit urbain ou rural. Et ceci permet d'autre part la coopération de cette deuxième portion avec une ceinture annulaire faisant jonction, notamment pour l'étanchéité de l'ensemble, entre les deux portions du mât, de sorte que cette ceinture annulaire peut porter sur le profil de la face extérieure des parois de liaison. When each of the connecting walls is in its radial operating position, the operator has formed an assembly whose second portion, in section perpendicular to the extension direction of the mast, has a closed perimeter, regular all around. This gives on the one hand a regular aesthetic appearance to the portion of the antenna support intended to be the most visible, which facilitates its integration in an environment that is urban or rural. And this allows on the other hand the cooperation of this second portion with an annular belt joining, in particular for sealing the assembly, between the two portions of the mast, so that this annular belt can bear on the profile of the outer face of the connecting walls.
Dans sa configuration assemblée, le périmètre fermé de l'ensemble, ou tout au moins de la deuxième portion, du support d'antennes est formé par le profil des faces extérieures des parois et des antennes, en alternance. Ainsi, selon la forme des antennes, on pourra avoir, en section perpendiculaire à la direction d'allongement du mât, un périmètre qui présente un profil circulaire, polygonale, ou une pluralité de secteurs rectilignes formés par les antennes et une pluralité de secteurs courbés formés par les parois. In its assembled configuration, the closed perimeter of the assembly, or at least the second portion, of the antenna support is formed by the profile of the outer faces of the walls and antennas, alternately. Thus, depending on the shape of the antennas, there may be, in section perpendicular to the direction of elongation of the mast, a perimeter that has a circular profile, polygonal, or a plurality of rectilinear sectors formed by the antennas and a plurality of curved sectors. formed by the walls.
L'opérateur pose enfin la plaque de fermeture 14 en couverture de l'extrémité supérieure des antennes 2 pour compléter la fermeture de la deuxième portion, et il peut alors réaliser la
mise en mouvement de la deuxième portion du support d'antennes pour le disposer à la verticale, c'est-à-dire dans le prolongement de la première portion 4. Pour cela, l'opérateur s'assure de la bonne liaison de la pompe hydraulique avec le moyen d'actionnement 72, notamment le vérin à double effet, et il s'assure de la fixation correcte du vérin et de la pompe par rapport à l'embase 22, notamment. The operator finally affixes the closure plate 14 to cover the upper end of the antennas 2 to complete the closure of the second portion, and he can then perform the setting in motion the second portion of the antenna support to arrange it vertically, that is to say in the extension of the first portion 4. For this, the operator ensures the proper connection of the hydraulic pump with the actuating means 72, including the double-acting cylinder, and it ensures the correct attachment of the cylinder and the pump relative to the base 22, in particular.
Une fois le support d'antennes 1 dans sa configuration assemblée, l'opérateur solidarise l'ensemble par le boulonnage des seconds bras de fixation 42 autour des montants 24. Le second bras principal, disposé à l'opposé de la tige 35 formant l'axe d'articulation, est boulonné directement sur le montant 24, alors que sa fourche s'est engagée directement autour du montant, et les deux bras ajustables sont manipulés de sorte à rabattre l'aile amovible de la fourche autour du montant correspondant, puis boulonnés sur ce montant. Once the antenna support 1 in its assembled configuration, the operator secures the assembly by bolting the second fixing arm 42 around the uprights 24. The second main arm, disposed opposite the rod 35 forming the hinge pin, is bolted directly to the upright 24, while its fork is engaged directly around the upright, and the two adjustable arms are manipulated so as to fold the removable wing of the fork around the corresponding amount, then bolted on this amount.
L'opérateur ferme alors les capots 10, puis pose enfin sur le support d'antennes 1 la ceinture annulaire 16, qui peut avantageusement être fixée sur l'extrémité supérieure des montants 24.
The operator then closes the covers 10, then finally places on the antenna support 1 the annular belt 16, which can advantageously be fixed on the upper end of the uprights 24.
