Description

Dispositif de soutien pour câble d’antenneAntenna cable support device

Le domaine technique de l'invention est celui des dispositifs permettant le soutien de câbles d’antennes télescopiques.The technical field of the invention is that of devices allowing the support of telescopic antenna cables.

Les dispositifs mobiles de télécommunication ou de goniométrie nécessitent l’emploi d’antennes escamotables pour des raisons de facilité de transport. Ces antennes doivent par ailleurs pouvoir être érigées à plusieurs mètres de hauteur pour avoir des performances satisfaisantes. Pour cela il est classique de mettre en œuvre des antennes télescopiques ou pliantes.Mobile telecommunications or direction finding devices require the use of retractable antennas for reasons of ease of transport. These antennas must also be able to be erected at a height of several meters in order to have satisfactory performance. For this it is conventional to implement telescopic or folding antennas.

Le brevet EP0518139 divulgue une remorque comportant une antenne de réception comportant un mât télescopique de longueur modifiable. En outre cette antenne peut être placée horizontalement par pivotement pour être transportée une fois repliée, ou bien pivotée verticalement avant d’être dépliée. Les besoins en alimentation électrique et en transmission de signal de ce type d’antenne impliquent d’avoir des câbles conducteurs qui relient l’antenne à des moyens d’alimentation et de traitement du signal situés au sol.Patent EP0518139 discloses a trailer comprising a reception antenna comprising a telescopic mast of modifiable length. In addition, this antenna can be placed horizontally by pivoting to be transported once folded, or pivoted vertically before being unfolded. The power supply and signal transmission needs of this type of antenna involve having conductive cables that connect the antenna to power supply and signal processing means located on the ground.

Les câbles sont particulièrement vulnérables aux pliages et dépliages et cela d’autant plus si le rayon de courbure minimal des câbles est élevé (plusieurs dizaines de centimètres) ce qui rend bien souvent l’intégration des câbles dans une telle antenne très compliquée. En effet les câbles utilisés avec de telles antennes ont tous un rayon de pliage minimal à respecter. Un pliage qui serait réalisé suivant un rayon qui serait inférieur au rayon minimal spécifié conduirait à une détérioration du câble (rupture des conducteurs ou des couches isolantes par exemple). The cables are particularly vulnerable to folding and unfolding, all the more so if the minimum radius of curvature of the cables is high (several tens of centimeters) which very often makes the integration of the cables in such an antenna very complicated. In fact, the cables used with such antennas all have a minimum bending radius to be respected. A bend which would be carried out along a radius which would be less than the specified minimum radius would lead to a deterioration of the cable (breakage of the conductors or of the insulating layers for example).

De plus, les câbles de par leur masse apportent du ballant à l’antenne ce qui engendre des phénomènes d’oscillation de l’antenne nuisibles aux transmissions et à la longévité de l’antenne et des câbles, en particulier au niveau de leurs connections.In addition, the cables by their mass bring sway to the antenna which generates phenomena of oscillation of the antenna harmful to the transmissions and to the longevity of the antenna and the cables, in particular at the level of their connections. .

L’invention propose de résoudre un problème d’intégration des câbles à fort rayon minimal de courbure avec une antenne télescopique. L’invention propose ainsi un dispositif permettant d’assurer le soutien des câbles au cours du déploiement et du repli de l’antenne tout en assurant le respect des rayons minimaux de courbure des câbles. The invention proposes to solve a problem of integrating cables with a high minimum radius of curvature with a telescopic antenna. The invention thus proposes a device making it possible to ensure the support of the cables during the deployment and folding of the antenna while ensuring compliance with the minimum radii of curvature of the cables.

L’invention propose de résoudre également un problème de solidité et de longévité des câbles pour antennes télescopiques. The invention also proposes to solve a problem of solidity and longevity of cables for telescopic antennas.

L’invention a ainsi pour objet un dispositif de soutien pour au moins un câble d’une antenne télescopique, lequel dispositif de soutien comporte un bras comportant au moins deux sections articulées l’une à l’autre grâce à une charnière, une première extrémité du bras étant destinée à être rendue solidaire par une première liaison pivot d’un support fixe recevant un pied de l’antenne et une seconde extrémité du bras étant destinée à être rendue solidaire d’une tête de l’antenne par une seconde liaison pivot de manière à ce que la sortie de l’antenne déplie le bras et que la rentrée de l’antenne replie le bras, chaque section du bras comportant au moins une goulotte destinée à contenir au moins un câble, un moyen de guidage du ou des câbles étant situé au voisinage de la charnière de façon à éviter les mouvements du ou des câbles selon une direction parallèle à l’axe de la charnière, au moins un moyen de tension du ou des câbles étant solidaire de la seconde extrémité du bras, caractérisé en ce que le moyen de tension du ou des câbles pourra comporter au moins une conduite disposée dans le prolongement d’une goulotte et présentant deux portions successives ayant des courbures dont les rayons sont au moins égaux au rayon de courbure minimal admissible par le ou les câbles, les deux portions ayant des orientations inverses l’une de l’autre, la conduite ayant ainsi une forme en S, une première portion de conduite étant destinée à orienter le ou les câbles en direction de la tête d’antenne lorsque le bras est replié, et une seconde portion de conduite ayant un profil ouvert permettant de laisser le ou les câbles sortir de la seconde portion de conduite pour s’orienter librement vers la tête d’antenne lorsque le bras est en position repliée, la courbure de la seconde portion de conduite permettant par ailleurs de tendre le ou les câbles lorsque le bras est en position dépliée.The subject of the invention is thus a support device for at least one cable of a telescopic antenna, which support device comprises an arm comprising at least two sections articulated to one another by means of a hinge, a first end of the arm being intended to be secured by a first pivot connection to a fixed support receiving a foot of the antenna and a second end of the arm being intended to be secured to a head of the antenna by a second pivot connection so that the exit of the antenna unfolds the arm and the retraction of the antenna folds the arm, each section of the arm comprising at least one chute intended to contain at least one cable, a means for guiding the cables being located in the vicinity of the hinge so as to avoid movement of the cable(s) in a direction parallel to the axis of the hinge, at least one means for tensioning the cable(s) being secured to the second end of the arm, characterized é in that the means for tensioning the cable or cables may comprise at least one conduit arranged in the extension of a chute and having two successive portions having curvatures whose radii are at least equal to the minimum radius of curvature admissible by the cable or the cables, the two portions having opposite orientations to each other, the pipe thus having an S-shape, a first pipe portion being intended to orient the cable or cables in the direction of the antenna head when the arm is folded, and a second pipe portion having an open profile allowing the cable(s) to exit from the second pipe portion to move freely towards the antenna head when the arm is in the folded position, the curvature of the second pipe portion also allowing the cable(s) to be tensioned when the arm is in the unfolded position.

Avantageusement, le moyen de tension pourra également comporter un tambour destiné à être rendu solidaire de la tête d’antenne et comportant au moins un profil courbe de rayon au moins égal au rayon de courbure minimal admissible par le ou les câbles, tambour sur lequel s’enroulent le ou les câbles en fonction de la position de l’antenne.Advantageously, the tensioning means may also comprise a drum intended to be secured to the antenna head and comprising at least one curved profile with a radius at least equal to the minimum radius of curvature admissible by the cable or cables, drum on which s roll up the cable(s) depending on the position of the antenna.

Selon un mode particulier de réalisation, le moyen de guidage du ou des câbles au niveau de la charnière pourra comporter deux flancs sensiblement verticaux solidaire d’une section de bras en sortie de goulotte, flancs disposés de part et d’autre du ou des câbles de façon à le ou les canaliser latéralement tout en les laissant libres de se mouvoir verticalement.According to a particular embodiment, the means for guiding the cable(s) at the hinge may comprise two substantially vertical flanks integral with an arm section at the chute outlet, flanks arranged on either side of the cable(s). so as to channel it or them laterally while leaving them free to move vertically.

Avantageusement, chaque section du bras pourra comporter deux goulottes parallèles recevant chacune un câble.Advantageously, each section of the arm may comprise two parallel chutes each receiving a cable.

Les goulottes de chaque section pourront être alors espacées d’une distance ménageant un espace destiné à permettre le positionnement de l’antenne.The ducts of each section can then be spaced apart by a distance leaving a space intended to allow the positioning of the antenna.

L’invention sera mieux comprise à la lumière de la description suivante, description faite au regard des dessins en annexe, dessins dans lesquels :The invention will be better understood in the light of the following description, description made with regard to the attached drawings, drawings in which:

représente une vue partielle de trois quarts arrière droit d’un véhicule porteur d’une antenne télescopique en position rentrée et d’un dispositif selon l’invention en position pliée. shows a partial three-quarter rear right view of a vehicle carrying a telescopic antenna in the retracted position and a device according to the invention in the folded position.

représente une vue détaillée de trois quarts arrière gauche d’un véhicule porteur d’une antenne télescopique en position rentrée et d’un dispositif selon l’invention en position pliée. shows a detailed left rear three-quarter view of a vehicle carrying a telescopic antenna in the retracted position and of a device according to the invention in the folded position.

représente une vue partielle d’un véhicule porteur d’une antenne télescopique en position sortie et d’un dispositif selon l’invention en position dépliée. shows a partial view of a vehicle carrying a telescopic antenna in the extended position and a device according to the invention in the unfolded position.

représente une vue de détail d’un dispositif selon l’invention en position dépliée. shows a detail view of a device according to the invention in the unfolded position.

Selon la , un véhicule militaire 100 porte une antenne télescopique 200 représentée ici en position rentrée, c’est-à-dire dans la position où la distance entre un pied 200a de l’antenne 200 et une tête 200b de l’antenne 200 est la plus réduite. According to , a military vehicle 100 carries a telescopic antenna 200 represented here in the retracted position, that is to say in the position where the distance between a foot 200a of the antenna 200 and a head 200b of the antenna 200 is the furthest. scaled down.

L’antenne 200 est solidaire d’un dispositif de soutien 1 pour des câbles 300, dispositif comportant un bras articulé 10 représenté ici en position repliée. Le bras 10 comporte deux sections 10a et 10b qui sont ici positionnées parallèlement l’une au-dessus de l’autre et qui sont reliées entre elles par une charnière 2 d’axe sensiblement perpendiculaire à l’axe de l’antenne 200.The antenna 200 is integral with a support device 1 for cables 300, device comprising an articulated arm 10 shown here in the folded position. The arm 10 comprises two sections 10a and 10b which are here positioned parallel one above the other and which are interconnected by a hinge 2 with an axis substantially perpendicular to the axis of the antenna 200.

Une première extrémité 1a du bras 10 est solidaire du pied 200a de l’antenne 200 (ou d’un support lié au véhicule 100 et portant ce pied d’antenne 200a) grâce à une première liaison pivot 3a d’axe sensiblement parallèle à l’axe de la charnière 2.A first end 1a of the arm 10 is secured to the foot 200a of the antenna 200 (or to a support connected to the vehicle 100 and carrying this antenna foot 200a) thanks to a first pivot connection 3a with an axis substantially parallel to the axis of the hinge 2.

Une seconde extrémité 1b du bras 10 est solidaire de la tête 200b de l’antenne 200 grâce à une seconde liaison pivot 3b d’axe sensiblement parallèle à l’axe de la charnière 2.A second end 1b of the arm 10 is secured to the head 200b of the antenna 200 thanks to a second pivot connection 3b with an axis substantially parallel to the axis of the hinge 2.

Chaque section 10a et 10b du bras 10 comporte deux goulottes 11 parallèles présentant chacune un profil fermé qui s’étend sur la longueur de chaque section 10a et 10b, de la liaison pivot 3a ou 3b jusqu’au voisinage de la charnière 2. Chaque goulotte 11 reçoit un câble 300 distinct. Selon le mode de réalisation de la , deux câbles parallèles 300 passent ainsi dans deux goulottes 11 distinctes. Each section 10a and 10b of the arm 10 comprises two parallel chutes 11 each having a closed profile which extends over the length of each section 10a and 10b, from the pivot connection 3a or 3b to the vicinity of the hinge 2. Each chute 11 receives a separate cable 300. According to the embodiment of the , two parallel cables 300 thus pass through two separate trunkings 11.

Au niveau de la charnière 2, le bras 10 comporte un moyen de guidage 4 pour chaque câble 300. Ces moyens de guidage 4 sont ici solidaires de la section inférieure 10b du bras 10. Chaque moyen de guidage 4 comporte une paire de flancs (ou tôles planes) 4a et 4b, parallèles et situés dans le prolongement des goulottes 11.At the level of the hinge 2, the arm 10 comprises a guide means 4 for each cable 300. These guide means 4 are here integral with the lower section 10b of the arm 10. Each guide means 4 comprises a pair of flanks (or flat sheets) 4a and 4b, parallel and located in the extension of the chutes 11.

Ces flancs 4a et 4b sont sensiblement verticaux et disposés de part et d’autre du câble 300 sortant de la goulotte 11. L’écartement entre les flancs 4a et 4b est tel qu’il permet de canaliser latéralement les câbles tout en les laissant libres de se mouvoir verticalement. Ainsi, le câble 300 est libre d’adopter un rayon de courbure qui le contraint le moins lorsqu’il est fléchi comme à la afin de de s’adapter à l’angle de pliage entre les deux section 10a et 10b du bras 10.These flanks 4a and 4b are substantially vertical and arranged on either side of the cable 300 exiting from the chute 11. The spacing between the flanks 4a and 4b is such that it allows the cables to be channeled laterally while leaving them free to move vertically. Thus, the cable 300 is free to adopt a radius of curvature which constrains it the least when it is bent as in the in order to adapt to the bending angle between the two sections 10a and 10b of the arm 10.

Selon la , l’antenne télescopique 200 est en position sortie, c’est-à-dire dans la position où la distance entre le pied 200a de l’antenne 200 et la tête 200b de l’antenne 200 est la plus grande. Le passage de la position rentrée à la position sortie se fait par la translation verticale de la tête d’antenne 200b. Ce faisant, la seconde liaison pivot 3b, qui solidarise la tête d’antenne 200b à la seconde extrémité 1b du dispositif 1, entraine le bras 10 vers le haut ce qui provoque le déploiement du bras 10 et son passage en position dépliée.According to , the telescopic antenna 200 is in the extended position, that is to say in the position where the distance between the foot 200a of the antenna 200 and the head 200b of the antenna 200 is the greatest. The transition from the retracted position to the extended position is done by the vertical translation of the antenna head 200b. In doing so, the second pivot link 3b, which secures the antenna head 200b to the second end 1b of the device 1, drives the arm 10 upwards which causes the deployment of the arm 10 and its passage into the unfolded position.

La seconde extrémité du bras 1b comporte un moyen de tension 5 des câbles 300.The second end of the arm 1b comprises a tensioning means 5 of the cables 300.

Le moyen de tension 5 des câbles 300 est visible aux figures 2, 3 et 4. Il comporte pour chaque câble 300 une conduite 6 disposée dans le prolongement des goulottes 11. Chaque conduite 6 présente deux portions successives 7 et 8 ayant des courbures de rayons au moins égaux au rayon de courbure minimal admissible par les câbles 300 afin qu’ils ne soient pas endommagés par un pliage. The tensioning means 5 of the cables 300 can be seen in FIGS. 2, 3 and 4. For each cable 300, it comprises a pipe 6 arranged in the extension of the troughs 11. Each pipe 6 has two successive portions 7 and 8 having radii curvatures at least equal to the minimum radius of curvature permitted by the cables 300 so that they are not damaged by bending.

Les deux portions 7 et 8 ont des orientations inverses l’une de l’autre, la conduite 6 ayant ainsi une forme en S comme on le voit clairement à la .The two portions 7 and 8 have opposite orientations to each other, the pipe 6 thus having an S-shape as can be clearly seen in .

Une première portion 7 de conduite est destinée à orienter le câble 300 en direction de la tête d’antenne lorsque le bras est replié (figures 1 et 2). Une seconde portion 8 de conduite a un profil ouvert (sans couvercle), comme on le voit aux figures 2 et 4. Ainsi cette seconde portion 8 laisse le câble 300 sortir de la seconde portion 8 de conduite pour s’orienter librement vers la tête d’antenne 200b lorsque le bras 10 est en position repliée (figures 1 et 2).A first pipe portion 7 is intended to orient the cable 300 in the direction of the antenna head when the arm is folded (FIGS. 1 and 2). A second portion 8 of pipe has an open profile (without cover), as seen in Figures 2 and 4. Thus this second portion 8 leaves the cable 300 out of the second portion 8 of pipe to move freely towards the head 200b antenna when the arm 10 is in the folded position (Figures 1 and 2).

Par ailleurs la courbure de la seconde portion 8 de conduite permet de tendre le câble 300 lorsque le bras 10 est en position dépliée (figures 3 et 4). Furthermore, the curvature of the second pipe portion 8 makes it possible to tension the cable 300 when the arm 10 is in the unfolded position (FIGS. 3 and 4).

De telles dispositions permettent tout à la fois de guider le câble 300 dans toutes les positions du bras 10 et d’absorber le mou du câble 300 lorsque le bras 10 est en position dépliée comme aux figures 3 et 4. Such arrangements make it possible both to guide the cable 300 in all positions of the arm 10 and to absorb the slack of the cable 300 when the arm 10 is in the unfolded position as in Figures 3 and 4.

L’absorption du mou consiste tendre le câble 300 pour lui imposer un parcours tel qu’il ne puisse être ballant. The absorption of the slack consists of stretching the cable 300 to impose a route such that it cannot be dangling.

Le moyen de tension 5 comporte par ailleurs un tambour 9 solidaire de la tête d’antenne 200b qui comporte un profil courbe de rayon au moins égal au rayon de courbure minimal admissible par le ou les câbles. Le câble 300 s’enroule sur le tambour 9, suivant un secteur plus ou moins grand en fonction de la position de l’antenne. The tensioning means 5 also comprises a drum 9 integral with the antenna head 200b which comprises a curved profile with a radius at least equal to the minimum radius of curvature admissible by the cable or cables. The cable 300 is wound on the drum 9, following a more or less large sector depending on the position of the antenna.

Le tambour 9 pourra comporter des côtés 9a guidant latéralement le câble 300.The drum 9 may include sides 9a laterally guiding the cable 300.

On note donc que l’absorption du mou du câble 300 se fait en continu, le câble 300 étant pour partie courbé autour du tambour 9 quand le bras 10 est plié ou bien courbé autour de la seconde portion 8 du conduit 6 lorsque le bras 10 est en position repliée. It is therefore noted that the absorption of the slack of the cable 300 is done continuously, the cable 300 being partly curved around the drum 9 when the arm 10 is bent or curved around the second portion 8 of the conduit 6 when the arm 10 is in the folded position.

Dans toutes les positions intermédiaires du bras, quand le bras 10 se déplie, le câble 300 se déroule du tambour 9 et simultanément s’enroule en proportions comparables au niveau de la seconde portion 8 du conduit, et inversement lorsque le bras 10 se replie. In all the intermediate positions of the arm, when the arm 10 unfolds, the cable 300 unwinds from the drum 9 and simultaneously rolls up in comparable proportions at the level of the second portion 8 of the duct, and vice versa when the arm 10 folds up.

Une telle disposition permet avantageusement de protéger les câbles des sollicitations mécaniques dues à un déploiement de l’antenne en cours de roulage ou bien durant l’usage de l’antenne sur des positions intermédiaires au plein déploiement. Such an arrangement advantageously makes it possible to protect the cables from mechanical stresses due to deployment of the antenna while driving or else during use of the antenna in positions intermediate to full deployment.

Ainsi, le dispositif de soutien 1 selon l’invention permet aux câbles de forte section (compris entre 40 et 100 mm de diamètre) de ne pas être abimés. Thus, the support device 1 according to the invention allows cables of large section (between 40 and 100 mm in diameter) not to be damaged.

Comme il a été déjà précisé, chaque section 10a et 10b du bras comporte donc deux goulottes 11 parallèles recevant chacune un câble 300. Une telle disposition permet de fournir un soutien pour deux câbles 300 distinct, un assurant par exemple l’alimentation électrique de l’antenne et l’autre la transmission des signaux émis ou reçus. Cette architecture permet par ailleurs de réaliser les section 10a et 10b du bras sous la forme d’une structure mécanosoudée présentant une certaine rigidité qui améliore la résistance de l’antenne.As has already been specified, each section 10a and 10b of the arm therefore comprises two parallel chutes 11 each receiving a cable 300. Such an arrangement makes it possible to provide support for two separate cables 300, one ensuring for example the power supply of the antenna and the other the transmission of the transmitted or received signals. This architecture also makes it possible to produce the sections 10a and 10b of the arm in the form of a mechanically welded structure having a certain rigidity which improves the resistance of the antenna.

L’invention permet ainsi d’apporter de la rigidité à l’antenne 200 en position haute, l’antenne étant alors moins sollicitée par les efforts orientés parallèlement aux axes des liaisons pivots 3a et 3b, ces efforts étant repris par les sections 10a et 10b du bras 10 et les charnières 2 et liaisons pivots 3a et 3b. On remarque aussi sur les figures que les goulottes 11 parallèles de chaque bras 10a et 10b sont espacées d’une distance qui ménage un espace dans lequel se positionne l’antenne 200.The invention thus makes it possible to provide rigidity to the antenna 200 in the high position, the antenna then being less stressed by the forces oriented parallel to the axes of the pivot links 3a and 3b, these forces being taken up by the sections 10a and 10b of the arm 10 and the hinges 2 and pivot connections 3a and 3b. It is also noted in the figures that the parallel channels 11 of each arm 10a and 10b are spaced apart by a distance which leaves a space in which the antenna 200 is positioned.

Cette symétrie des bras et des câbles de part et d’autre de l’antenne permet d’équilibrer les efforts subis par l’antenne qui ne se trouve donc pas contrainte en flexion en raison du dispositif de soutien 1. Ce montage permet également de minimiser l’effet du vent subi par l’antenne. This symmetry of the arms and cables on either side of the antenna makes it possible to balance the forces undergone by the antenna which is therefore not constrained in bending due to the support device 1. This assembly also makes it possible to minimize the effect of the wind experienced by the antenna.
