Description

L'invention a pour objet un dispositif support pour des antennes de radiocommunication.
Le territoire national est couvert d'antennes de réception et d'émission dans le cadre d'un maillage de radiocommunication. Si ce maillage est relativement simple en dehors des agglomérations, il n'en est pas de même à l'intérieur des villes.
En effet, les émissions sont alors coupées par la présence d'immeubles créant des écrans pour la transmission des signaux. Il est donc nécessaire d'augmenter le nombre des antennes et des sites.
Normalement, une antenne doit être placée aussi haut que possible, c'est pourquoi, les sites privilégiés pour la fixation d'antennes, sont les terrasses, les façades des immeubles de grande hauteur, les murs des édicules techniques des immeubles ou bien les châteaux d'eau... Sur ces sites sont installées des antennes panneaux ou paraboliques, dont les dimensions peuvent varier d'un diamètre de 30 à 240 centimètres pour une antenne parabolique, et d'une hauteur de 0.60 à 2.70 mètres et une section de 0.23 x 0.13 m. d'épaisseur pour une antenne panneau.
Ces antennes sont fixées sur des mats métalliques posés sur les terrasses ou bien en applique sur les murs de façade des derniers étages ou sur les murs des édicules techniques des immeubles, châteaux d'eau, silos... Chaque antenne doit être orientée vers les zones où l'on désire transmettre les signaux.
D'ou une grande importance du réglage de sa verticalité appelé tilt.The subject of the invention is a support device for radiocommunication antennas.
The national territory is covered by reception and transmission antennas as part of a radiocommunication network. If this network is relatively simple outside agglomerations, it is not the same inside cities.
In fact, emissions are cut off by the presence of buildings creating screens for the transmission of signals. It is therefore necessary to increase the number of antennas and sites.
Normally, an antenna should be placed as high as possible, this is why, the preferred sites for the fixing of antennas, are the terraces, the facades of high-rise buildings, the walls of the technical buildings of buildings or castles of water ... On these sites are installed panel or parabolic antennas, the dimensions of which can vary from a diameter of 30 to 240 centimeters for a parabolic antenna, and from a height of 0.60 to 2.70 meters and a section of 0.23 x 0.13 m. thick for a panel antenna.
These antennas are fixed on metal masts placed on the terraces or applied on the facade walls of the last floors or on the walls of technical buildings of buildings, water towers, silos ... Each antenna must be oriented towards areas where you want to transmit signals.
Hence the great importance of adjusting its verticality called tilt.

Actuellement les antennes sont fixées sur un mât par une bride haute et une bride basse, le réglage de la longueur des brides permet de faire varier le tilt. Currently the antennas are fixed on a mast by a high flange and low flange, length adjustment flanges allow to vary the tilt.

Ou bien selon une deuxième variante, l'antenne est fixée sur un support dont l'inclinaison limité à une dizaine de degrés est obtenue par le déplacement d'une barre dans une lumière de guidage ajourée, l'inclinaison manuelle du support fait varier le tilt.
Selon une troisième variante, l'antenne est fixée sur un support à l'avant du mât, le support étant lui-même fixé sur un mât vertical. Le réglage du tilt est assuré par l'action sur deux vis de réglage placées verticalement, et de sens contraire agissant sur deux équerres métalliques solidaires du support.Or in a second variant, the antenna is fixed on a support whose inclination limited to ten degrees is obtained by the displacement of a bar in an openwork guide light, the manual inclination of the support varies the tilt.
According to a third variant, the antenna is fixed on a support at the front of the mast, the support itself being fixed on a vertical mast. The tilt adjustment is ensured by the action on two adjustment screws placed vertically, and in the opposite direction acting on two metal brackets secured to the support.

Tout en permettant le réglage du tilt ces supports présentent des inconvénients. Par exemple le réglage n'est pas réalisé par une seule action continue et régulière, l'accessibilité de la partie haute de l'antenne nécessite qu'un opérateur grimpe sur des échelons fixés sur le mât.While allowing the tilt adjustment of these supports have drawbacks. For example, the setting is not not achieved by a single continuous and regular action, the accessibility of the upper part of the antenna requires that an operator climbs on steps fixed on the mast.

L'invention a pour but de créer un dispositif de support et de réglage d'une antenne, permettant une mise en oeuvre et un réglage de l'antenne plus efficace et dans de meilleures condition de sécurité, en réduisant le temps d'intervention des équipes de pose, la hauteur de travail au-dessus du sol ainsi que la durée et le nombre de tâches à exécuter au-dessus du vide à l'aplomb des façades, tout en conservant une grande rigidité du support sous vent de face et de profil, pour assurer la transmission des communications téléphoniques sans effet de résonance dans des conditions climatiques de vent extrême.The invention aims to create a support device and adjustment of an antenna, allowing an implementation and more efficient and better antenna tuning safety condition, reducing intervention time laying crews, working height above ground as well as the duration and number of tasks to be performed above emptiness above the façades, while preserving high rigidity of the support in front wind and profile, to ensure the transmission of communications without resonance under conditions extreme wind climates.

L'invention concerne d'une façon générale un dispositif de support et de réglage d'une antenne de radiocommunication fixée sur un bras support solidarisé à une coquille qui enserre le mât porteur vertical par l'intermédiaire d'un mécanisme qui permet le réglage en azimut autour de ce mât porteur et un réglage du tilt, caractérisé en ce que ce mécanisme comporte un organe de liaison rigide sensiblement horizontal passant par le mât porteur et par le bras support, cet organe étant solidarisé à la coquille et à une virole qui enserre un cylindre solidaire du bras support. L'organe de liaison rigide peut être constitué par un tube cylindrique, mais plus particulièrement selon l'invention l'organe de liaison rigide est constitué par deux éléments tubulaires concentriques rotatifs comportant un moyen d'immobilisation.
Le moyen d'immobilisation est avantageusement constitué par au moins une fente d'élasticité bordée par deux pattes reliées par des vis de serrage.
Plus particulièrement l'élément tubulaire périphérique est solidarisé à la demi virole qui permet d'enserrer le cylindre solidaire du bras support.
Selon une autre caractéristique avantageuse, un organe de réglage de longueur variable s'étend entre une fixation articulée au bras support d'antenne et une fixation articulée à l'organe de liaison rigide.
De façon préférentielle l'organe de réglage comprend deux tiges filetées à pas inverse, reliées par un manchon à double pas de vis.
Avantageusement l'organe de liaison rigide et le cylindre présentent un module d'inertie au moins égal à 0,9 fois le module d'inertie du mât porteur.
De manière avantageuse les deux éléments tubulaires comportent un moyen de limitation de la rotation relative de ces deux éléments, et plus particulièrement le moyen de limitation de la rotation est constitué par une lumière qui s'étend sur un quart de la circonférence d'un premier élément tubulaire et qui coopère avec une saillie du second élément tubulaire.
Pour certaines implantations d'antennes, notamment au dessus du vide, le dispositif de support et de réglage comporte avantageusement un organe de manoeuvre en rotation ménagé soit sur l'élément tubulaire périphérique soit sur la demi virole. Plus particulièrement cet organe de manoeuvre en rotation est centré sur l'axe des deux éléments tubulaires concentriques rotatifs, cet organe pouvant être atteint au travers d'ouvertures ménagées dans les demi coquilles. Cet organe de manoeuvre en rotation peut notamment être réalisé par une simple empreinte polygonale pouvant recevoir l'extrémité adaptée d'une tige de manoeuvre amovible pénétrant dans les ouvertures prévues à cet effet.The invention relates generally to a device for supporting and adjusting a radiocommunication antenna fixed on a support arm secured to a shell which encloses the vertical carrying mast by means of a mechanism which allows the adjustment in azimuth around this support mast and a tilt adjustment, characterized in that this mechanism comprises a substantially horizontal rigid connecting member passing through the support mast and the support arm, this member being secured to the shell and to a ferrule which encloses a cylinder secured to the support arm. The rigid connecting member can be constituted by a cylindrical tube, but more particularly according to the invention the rigid connecting member is constituted by two concentric rotating tubular elements comprising an immobilization means.
The immobilization means advantageously consists of at least one elasticity slot bordered by two tabs connected by clamping screws.
More particularly, the peripheral tubular element is secured to the half-shell which makes it possible to enclose the cylinder secured to the support arm.
According to another advantageous characteristic, a variable length adjustment member extends between an articulated attachment to the antenna support arm and an articulated attachment to the rigid connecting member.
Preferably, the adjusting member comprises two threaded rods with reverse pitch, connected by a sleeve with double screw pitch.
Advantageously, the rigid connecting member and the cylinder have an inertia module at least equal to 0.9 times the inertia module of the supporting mast.
Advantageously, the two tubular elements comprise a means for limiting the relative rotation of these two elements, and more particularly the means for limiting the rotation consists of a lumen which extends over a quarter of the circumference of a first tubular element and which cooperates with a projection of the second tubular element.
For certain antenna layouts, in particular above the vacuum, the support and adjustment device advantageously comprises an operating member in rotation formed either on the peripheral tubular element or on the half-ferrule. More particularly, this rotary actuator is centered on the axis of the two rotary concentric tubular elements, this member being attainable through openings made in the half shells. This rotary actuator can in particular be produced by a simple polygonal imprint which can receive the adapted end of a removable operating rod penetrating into the openings provided for this purpose.

Le dispositif de support et de réglage d'antenne conçu conformément à l'invention présente un certain nombre d'avantages. Il permet la mise en oeuvre et le réglage rapide et précis de l'antenne ce qui réduit le temps d'intervention des compagnons sur les toitures et donc l'exposition aux risques, ainsi que la diminution de la hauteur de travail au dessus de la toiture, tout en conservant une grande rigidité sous vent de face et de profil, et assure ainsi des transmissions téléphoniques de très bonne qualité.
De plus, selon le mode préférentiel de réalisation de l'invention, par rotation d'un quart de tour des deux éléments tubulaires concentriques constituant l'organe de liaison rigide, l'antenne peut être placée en position horizontale avant de faire pivoter l'ensemble autour du mât porteur, ce qui permet des implantations d'antennes sur les rebords des ouvertures des constructions alors qu'aucun dispositif de support de réglage antérieurement connu ne permettait une telle mise en oeuvre. The antenna support and adjustment device designed in accordance with the invention has a number of advantages. It allows the implementation and the fast and precise adjustment of the antenna which reduces the intervention time of the companions on the roofs and therefore the exposure to risks, as well as the reduction of the working height above the roof, while retaining great rigidity in front and profile wind, and thus ensures very good quality telephone transmissions.
In addition, according to the preferred embodiment of the invention, by rotation of a quarter turn of the two concentric tubular elements constituting the rigid connecting member, the antenna can be placed in a horizontal position before rotating the together around the carrying mast, which allows the implantation of antennas on the edges of the openings of constructions when no previously known adjustment support device allowed such an implementation.

Dans un autre mode de réalisation le support d'antenne est fixé sur une paroi en béton ou en maçonnerie. Dans ce cas de figure la coquille qui enserre le mât porteur est remplacée par un tube cylindrique vertical enserré dans une coquille basse et une coquille haute, chaque coquille étant constituée par deux demi coquilles liaisonnées par boulonnage et solidaires d'une platine boulonnée sur une paroi verticale.In another embodiment the antenna support is fixed to a concrete or masonry wall. In that case the shell that surrounds the carrying mast is replaced by a vertical cylindrical tube enclosed in a low shell and a high shell, each shell being constituted by two half shells linked by bolting together with a plate bolted to a vertical wall.

Mais l'invention sera mieux comprise par la description détaillée de certains modes de réalisation donnés à titre de simples exemples et représentés sur les dessins annexés. La figure 1 est une vue en élévation d'un ensemble mât/support d'antenne/antenne.
La figure 2 est une vue en élévation partielle d'une variante ensemble mât/support d'antenne/antenne en applique sur un mur de façade.
La figure 3 est une vue en élévation détaillant le dispositif de support et de réglage d'une antenne représenté à la figure 1.
La figure 4 est une vue par dessus du dispositif représenté à la figure 3.
La figure 5 est une vue partielle en coupe du dispositif de support et de réglage représenté à la figure 3, complété par un organe de manoeuvre en rotation.
Selon les deux modes de réalisation représentés aux figures 1 et 2, les antennes de télécommunication 20, du type «antenne panneau», sont fixées par les moyens habituels sur les bras supports 7 réalisés à partir d'une poutrelle à section en U, dont les ailes sont conformées pour être fixées à une demi virole qui contribue à permettre la rotation autour du cylindre 6 au moyen des organes de réglage 11. However, the invention will be better understood from the detailed description of certain embodiments given by way of simple examples and shown in the appended drawings. Figure 1 is an elevational view of a mast / antenna support / antenna assembly.
FIG. 2 is a partial elevation view of a variant mast / antenna support / antenna applied to a facade wall.
FIG. 3 is an elevation view detailing the device for supporting and adjusting an antenna shown in FIG. 1.
FIG. 4 is a view from above of the device shown in FIG. 3.
Figure 5 is a partial sectional view of the support and adjustment device shown in Figure 3, supplemented by a rotary actuator.
According to the two embodiments shown in FIGS. 1 and 2, the telecommunication antennas 20, of the "panel antenna" type, are fixed by the usual means on the support arms 7 produced from a beam with a U-section, of which the wings are shaped to be fixed to a half-ferrule which contributes to allowing rotation around the cylinder 6 by means of the adjustment members 11.

Plus particulièrement selon la figure 1, l'organe de liaison rigide 18 permet le basculement à l'horizontal de l'ensemble, antenne 20 et le bras support 7, par rotation autour de l'axe sensiblement horizontal passant par le mât porteur fixe 3 et par le bras support 7, l'ensemble du dispositif étant fixé à ce mât porteur 3 par la coquille (1,2) Plus particulièrement selon la figure 2, l'organe de liaison rigide 19 est réduit à un simple tube cylindrique dont les extrémités sont conformées pour être soudées d'une part sur une demi virole qui contribue à permettre la rotation autour du cylindre 6, et d'autre part sur le mât porteur vertical 3' qui peut pivoter autour de la coquille qui est solidarisée au mur porteur par l'intermédiaire d'une embase sur lesquelles sont soudées deux demi coquilles hautes et basses, l'antenne étant définitivement immobilisée après réglage, par serrage des deux autres demi coquilles libres haute et basse.
Sur les figures 3 et 4, on a représenté l'ensemble d'un dispositif support d'antenne fixé sur un mat vertical 3. Dans le mode de réalisation représenté sur ces figures, deux demi coquilles 1 et 2 peuvent se déplacer verticalement sur un cylindre de grande longueur constituant un mât 3 et tourner autour de ce mât 3, selon l'invention sur la demi coquille 1 est soudé un tube 4 qui constitue le premier élément tubulaire de l'ensemble de rotation 18, ce tube 4 étant fixé sur le mât 3 au moyen de la seconde demi coquille 2 par serrage des boulons 5 après réglage en altitude et en azimut.
Sur le tube 4 est emboíté le second élément tubulaire de l'ensemble de rotation 18, qui est essentiellement constitué par un tube 10, dont le moyen d'immobilisations sur ce tube 4 est constitué par une fente d'élasticité ménagée à la partie supérieure, cette fente étant bordée par deux pattes rapprochables par serrage de deux boulons. L'extrémité du tube 10 dirigée vers l'antenne est prolongée par la demi virole 9 soudée à cette extrémité, cette demi virole 9 étant reliée par quatre boulons 14 sur l'autre demi virole 8. Lorsque les quatre boulons 14 de liaison de la virole 8, 9 ne sont pas bloqués, le cylindre 6 soudé sur les ailes du support d'antenne 7 peut alors tourner dans cette virole au moyen de l'organe de réglage 11 qui est dans cet exemple un ridoir formé par un manchon à double pas de vis en prise avec deux tiges filetées de pas inverses, qui se terminent chacune par une articulation 12 et 13 dont la chape est reliée par un axe amovible à une plaque de liaison, respectivement soudée sur le bras support 7 et sur le tube 10. Après réglage en tilt de l'antenne par rotation du manchon, le simple serrage des quatre boulons 14 assure le positionnement définitif de l'antenne. L'utilisation d'articulations démontables 12 et 13 permet de démonter le ridoir 11 et de l'utiliser sur d'autres dispositifs de support et de réglage d'antennes conformes à l'invention.
Pour faciliter le basculement de l'antenne 20 entre une position de fonctionnement sensiblement verticale et une position d'intervention et/ou de manutention sensiblement horizontale selon l'exemple représenté à la figure 4, l'élément tubulaire concentrique extérieur 10 est muni d'une lumière 16 qui coopère avec une vis à tête cylindrique 17 fixée sur l'élément tubulaire concentrique interne 4, l'ensemble permettant de limiter le basculement à un quart de tour.
Dans le cas où en position de fonctionnement l'antenne 20 et son bras support 7 sont au dessus du vide, il est alors avantageux de pouvoir basculer l'antenne d'une position verticale à une position horizontale en utilisant un organe de manoeuvre en rotation qui peut être par exemple un levier terminé par une poignée qui est solidaire du tube périphérique 10. Préférentiellement, pour effectuer un tel basculement, l'organe de manoeuvre en rotation 21 est situé sur la demi virole 9 et centré sur l'axe des deux tubes concentriques 4 et 10. La figure 5 représente un mode de réalisation particulier d'un tel organe de manoeuvre qui est constitué par une perforation de section hexagonale 21, le mat porteur et les deux demi coquilles 1 et 2 étant munies d'ouvertures afin de permettre l'introduction d'une tige de manoeuvre 22 dont l'extrémité forme un hexagone pouvant pénétrer dans la perforation 21.More particularly according to Figure 1, the rigid connecting member 18 allows the horizontal tilting of the assembly, antenna 20 and the support arm 7, by rotation about the substantially horizontal axis passing through the fixed support mast 3 and by the support arm 7, the entire device being fixed to this support mast 3 by the shell (1,2) More particularly according to FIG. 2, the rigid connecting member 19 is reduced to a simple cylindrical tube, the ends are shaped to be welded on the one hand on a half ferrule which contributes to allow rotation around the cylinder 6, and on the other hand on the vertical support mast 3 'which can pivot around the shell which is secured to the bearing wall by means of a base on which are welded two high and low half shells, the antenna being definitively immobilized after adjustment, by tightening of the other two free high and low half shells.
In Figures 3 and 4, there is shown the assembly of an antenna support device fixed on a vertical mast 3. In the embodiment shown in these figures, two half shells 1 and 2 can move vertically on a cylinder of great length constituting a mast 3 and turn around this mast 3, according to the invention on the half-shell 1 is welded a tube 4 which constitutes the first tubular element of the rotation assembly 18, this tube 4 being fixed on the mast 3 by means of the second half-shell 2 by tightening the bolts 5 after adjustment in altitude and in azimuth.
On the tube 4 is fitted the second tubular element of the rotation assembly 18, which is essentially constituted by a tube 10, the immobilization means of which on this tube 4 is constituted by an elasticity slot made in the upper part , this slot being bordered by two legs which can be brought together by tightening two bolts. The end of the tube 10 directed towards the antenna is extended by the half-ferrule 9 welded to this end, this half-ferrule 9 being connected by four bolts 14 on the other half-ferrule 8. When the four connecting bolts 14 of the ferrule 8, 9 are not blocked, the cylinder 6 welded to the wings of the antenna support 7 can then rotate in this ferrule by means of the adjusting member 11 which is in this example a turnbuckle formed by a double sleeve thread screw engaged with two threaded rods of opposite pitch, each ending in an articulation 12 and 13, the yoke of which is connected by a removable pin to a connecting plate, respectively welded to the support arm 7 and to the tube 10 After adjusting the antenna tilt by rotating the sleeve, the simple tightening of the four bolts 14 ensures the final positioning of the antenna. The use of removable joints 12 and 13 makes it possible to disassemble the turnbuckle 11 and to use it on other support and antenna adjustment devices in accordance with the invention.
To facilitate the tilting of the antenna 20 between a substantially vertical operating position and a substantially horizontal intervention and / or handling position according to the example shown in FIG. 4, the external concentric tubular element 10 is provided with a light 16 which cooperates with a cylindrical head screw 17 fixed on the internal concentric tubular element 4, the assembly making it possible to limit the tilting to a quarter of a turn.
In the case where in the operating position the antenna 20 and its support arm 7 are above the vacuum, it is then advantageous to be able to tilt the antenna from a vertical position to a horizontal position by using a rotary actuator which can for example be a lever terminated by a handle which is integral with the peripheral tube 10. Preferably, to effect such a tilting, the rotary actuating member 21 is located on the half-ferrule 9 and centered on the axis of the two concentric tubes 4 and 10. FIG. 5 represents a particular embodiment of such an operating member which is constituted by a perforation of hexagonal section 21, the supporting mast and the two half shells 1 and 2 being provided with openings so allow the introduction of an operating rod 22, the end of which forms a hexagon which can penetrate the perforation 21.
