Description

concerne un support d'antenne auto-radio, comportant une embase, qui est aménagée pour être fixée sur la carrosserie de l'automobile, et sur laquelle la pièce d'extrémité de l'antenne est montée pivotante; ce support est caractérisé en ce que la pièce d'extrémité est une pièce creuse, dans laquelle est monté, de préférence de façon amovible, un manchon tubulaire, de préférence métallique, comportant intérieurement des moyens pour la fixation amovible du bout de l'antenne, qui est engagé dans l'une des extrémités dudit manchon.relates to a car radio antenna support, comprising a base, which is arranged to be fixed to the body of the automobile, and on which the end piece of the antenna is pivotally mounted; this support is characterized in that the end piece is a hollow piece, in which is mounted, preferably removably, a tubular sleeve, preferably metallic, internally comprising means for the removable fixing of the end of the antenna , which is engaged in one of the ends of said sleeve.

Dans la forme de réalisation préférée qui est décrite dans le brevet FPA 83 05912 la pièce creuse d'extrémité est en matière synthétique, par exemple moulée, et de préférence colorée en noir; d'autre part, le manchon tubulaire est réalisé à partir d'une pièce métallique plate, par cintrage, puis agrafage de ses bords rapprochés suivant une génératrice du manchon tubulaire.In the preferred embodiment which is described in patent FPA 83 05912 the hollow end piece is made of synthetic material, for example molded, and preferably colored black; on the other hand, the tubular sleeve is produced from a flat metal part, by bending, then stapling of its close edges along a generatrix of the tubular sleeve.

La présente invention concerne un
support d'antenne selon le brevet FPA' 8305912 qui s'en distingue notamment par la réalisation du manchon tubulaire et de la pièce creuse d'extrémité, dans laquelle ledit manchon est monté.The present invention relates to a
antenna support according to patent FPA '8305912 which is distinguished in particular by the production of the tubular sleeve and the hollow end piece, in which said sleeve is mounted.

Le support d'antenne auto-radio selon la présente invention estThe car radio antenna support according to the present invention is

caractérisé par le fait que le manchon tubulaire est constitué par une pièce moulée, de préférence métallique, qui est engagée dans la pièce creuse d'extrémité de façon à pouvoir en être aisément séparée.characterized in that the tubular sleeve consists of a molded piece, preferably metallic, which is engaged in the hollow end piece so that it can be easily separated therefrom.

En réalisant, selon la présente invention, le manchon tubulaire sous la forme d'une pièce moulée, on obtient une réduction sensible du prix de revient du support d'antenne, et, en même temps, un accroissement de la résistance mécanique dudit manchon; en montant le manchon tubulaire dans la pièce creuse d'extrémité de façon à pouvoir aisément les séparer l'une de l'autre, on obtient la possibilité de pouvoir adapter, aux mêmes manchons moulés,de faible prix, notamment grâce à l'absence de finition extérieure, des pièces creuses d'extrémité, de réalisations différentes, présentant notamment des finitions extérieures différentes; par suite, les mêmes manchons moulés peuvent être utilisés aussi bien avec des pièces creuses d'extrémité,. par exemple en matière synthétique, colorée en noir ou présentant une finition externe noir mat selon le brevet FPA 8305912, qu'avec des pièces présentant une finition extérieure métallisée, par exemple chromée, selon une autre caractéristique du support d'antenne selon la présente invention. La possibilité d'utiliser les mêmes manchons tubulaires pour des supports d'antennes dont les pièces d'extrémités présentent des matériaux constitutifs, des procédés de fabrication et éventuellement des finitions différentes, se traduit par des économies substantielles tant au niveau de la fabrication que du stockage. Enfin, l'utilisation d'un manchon tubulaire moulé, notamment métallique, est particulièrement avantageuse pour l'adaptation, à l'intérieur de ce manchon tubulaire, de moyens de différents types pour la fixation amovible du bout de l'antenne; en effet, un même type de manchon tubulaire moulé selon la présente invention peut être aisément adapté, lors de sa fabrication, aussi bien à la fixation du bout de l'antenne par vissage, en le munissant d'un taraudage intérieur, qu'à la fixation, rapidement libérable, du bout de l'antenne, soit à l'aide d'un dispositif d'encliquetage, tel que celui illustré sur la figure 5 du brevet français précité Soit à l'aide d'un accouplement à baîonnette, selon la présente invention. Ce dernier mode de fixation offre notamment l'intérêt d'assurer un positionnement angulaire précis de l'antenne par rapport à la carrosserie de l'automobile, ce qui est indispensable en particulier dans le cas d'une antenne dipôle.By producing, according to the present invention, the tubular sleeve in the form of a molded part, a substantial reduction in the cost price of the antenna support is obtained, and, at the same time, an increase in the mechanical resistance of said sleeve; by mounting the tubular sleeve in the hollow end piece so that they can easily be separated from one another, we obtain the possibility of being able to adapt, to the same molded sleeves, of low price, in particular thanks to the absence of external finish, hollow end pieces, of different embodiments, in particular having different exterior finishes; as a result, the same molded sleeves can be used with hollow end pieces as well. for example made of synthetic material, colored black or having a matt black external finish according to patent FPA 8305912, only with parts having a metallized external finish, for example chromed, according to another characteristic of the antenna support according to the present invention . The possibility of using the same tubular sleeves for antenna supports whose end pieces have constituent materials, manufacturing processes and possibly different finishes, results in substantial savings both in terms of manufacturing and storage. Finally, the use of a molded tubular sleeve, in particular metallic, is particularly advantageous for the adaptation, inside this tubular sleeve, of means of different types for the removable fixing of the end of the antenna; in fact, the same type of tubular sleeve molded according to the present invention can be easily adapted, during its manufacture, both for fixing the end of the antenna by screwing, by providing it with an internal thread, as well as for fixing, quickly releasable, the end of the antenna, either using a latching device, such as that illustrated in FIG. 5 of the aforementioned French patent Either using a bayonet coupling, according to the present invention. This latter method of attachment offers in particular the advantage of ensuring precise angular positioning of the antenna relative to the body of the automobile, which is essential in particular in the case of a dipole antenna.

A titre d'exemple, on a décrit ci-dessous et illustré schématiquement au dessin annexé, une forme de réalisation d'un support d'antenne de toit selon la présente invention.By way of example, there is described below and illustrated schematically in the accompanying drawing, a form for producing a roof antenna support according to the present invention.

La figure 1 est une vue de cette forme de réalisation, en coupe par un plan passant par l'axe de l'antenne et par l'axe de la tige de fixation de l'embase du support sur la carrosserie du véhicule.Figure 1 is a view of this embodiment, in section through a plane passing through the axis of the antenna and through the axis of the rod for fixing the base of the support on the vehicle body.

La figure 2 est une vue en coupe suivant la ligne VII-VII de la figure 1,.Figure 2 is a sectional view along line VII-VII of Figure 1 ,.

Les différents composants de la forme de réalisation de l'invention qui est illustrée sur les figures 1 et 2 du dessin annexé ont été désignés par les mêmes références que les composants homologues des formes de réalisation illustrées sur les figures 1 à 5 du brevet FpA 8305912. La description de la forme de réalisation illustrée sur les figures 1 et 2 peut donc être limitée à celle des composants par lesquels elle diffère des formes de réalisation décrites dans le brevet français précité.The various components of the embodiment of the invention which is illustrated in FIGS. 1 and 2 of the appended drawing have been designated by the same references as the homologous components of the embodiments illustrated in FIGS. 1 to 5 of patent FpA 8305912 The description of the embodiment illustrated in FIGS. 1 and 2 can therefore be limited to that of the components by which it differs from the embodiments described in the aforementioned French patent.

De l'élément métallique, 1b, de l'embase du support d'antenne selon la présente invention, se détache, vers la droite des figures 1. et 2, une oreille unique, 1b1, dont le plan de symétrie médian est décalé par rapport à l'axe de la tige filetée 2, servant, avec les deux écrous, 2a et 2b, à la fixation de l'élément 1a de l'embase sur la carrosserie du véhicule.To the right of FIGS. 1 and 2, from the metal element, 1b, of the base of the antenna support according to the present invention, stands a single ear, 1b1, whose median plane of symmetry is offset by relative to the axis of the threaded rod 2, serving, with the two nuts, 2a and 2b, for fixing the element 1a of the base to the vehicle body.

Un manchon tubulaire 3, constitué par une pièce métallique moulée, par exemple en zamac, est prolongé, vers la gauche des figures 1 et .2, par une seule oreille, 3a (figure 2), dont le plan de symétrie médian est également décalé, dans le sens opposé, par rapport à l'axe de la tige filetée 2, et par rapport à l'axe longitudinal A du manchon tubulaire 3, qui se trouve toujours sensiblement dans le même plan que l'axe de la tige filetée 2. Les deux oreilles, 1b1 et 3a, sont assemblées de manière à former un palier rotatif, au moyen d'un axe qui, dans la forme de réalisation illustrée, est matérialisé par la tige 4a d'un boulon, qui peut être brut, c'est-à-dire sans finition, notamment au niveau de sa tête 4b. Dans cette forme de réalisation, la tige 4a de ce boulon traverse librement des perçages alignés des oreilles 3a et 1b1, et elle est vissée dans un écrou 11, immobilisé en rotation sur la face externe de l'oreille 3a, par engagement de l'écrou 11, par exemple hexagonal, dans un logement de section également hexagonale, aménagé dans ladite oreille 3a. De cette façon, l'ensemble du manchon tubulaire 3, de son oreille 3a, du boulon 4a-4b et de l'écrou 11, peut tourner librement par rapport à l'embase 1a-1b et à son oreille 1b1. Une rondelle faisant ressort, 5, est en outre interposée entre l'oreille 1b1 de l'embase1b et la tête 4b du boulon qui constitue l'axe du palier. La face de la rondelle 5, opposée à la tête 4b du boulon, coopère avec la face plane d'une rondelle mince, 16, qui est appliquée contre l'oreille fixe 1b1 de l'embase 1b; cette rondelle 16 est immobilisée en rotation par rapport au manchon tubulaire 3 et à son oreille 3a, notamment par engagement d'un appendice latéral 16a dans un évidement 17,aménagé dans la paroi externe du manchon tubulaire 3, au niveau de sa zone de raccordement avec l'oreille 3a. C'est donc cette rondelle 16 qui frotte contre l'oreille fixe, 1b1, lorsque le manchon tubulaire 3 pivote par rapport à ladite oreille 1b1, tandis que la rondelle 5, qui est interposée entre les deux éléments, 16 et 4b, solidaires en rotation du manchon tubulaire 3, assure le blocage de la tige 4a du boulon dans l'écrou 11, de façon à éviter tout desserrage dudit boulon, qui serait dû aux vibrations et aux chocs auxquels le véhicule automobile est exposé.A tubular sleeve 3, constituted by a molded metal part, for example in zamac, is extended, to the left of Figures 1 and .2, by a single ear, 3a (Figure 2), whose median plane of symmetry is also offset , in the opposite direction, relative to the axis of the threaded rod 2, and relative to the longitudinal axis A of the tubular sleeve 3, which is always substantially in the same plane as the axis of the threaded rod 2 The two ears, 1b1 and 3a, are assembled so as to form a rotary bearing, by means of an axis which, in the illustrated embodiment, is materialized by the rod 4a of a bolt, which can be rough, that is to say without finishing, especially at the level of its head 4b. In this embodiment, the rod 4a of this bolt freely crosses aligned holes of the ears 3a and 1b1, and it is screwed into a nut 11, immobilized in rotation on the external face of the ear 3a, by engagement of the nut 11, for example hexagonal, in a housing also hexagonal in section, arranged in said ear 3a. In this way, the assembly of the tubular sleeve 3, of its ear 3a, of the bolt 4a-4b and of the nut 11, can rotate freely relative to the base 1a-1b and to its ear 1b1. A spring washer 5 is also interposed between the ear 1b1 of the base1b and the head 4b of the bolt which constitutes the axis of the bearing. The face of the washer 5, opposite the head 4b of the bolt, cooperates with the flat face of a thin washer, 16, which is applied against the fixed ear 1b1 of the base 1b; this washer 16 is immobilized in rotation relative to the tubular sleeve 3 and to its ear 3a, in particular by engagement of a lateral appendage 16a in a recess 17, arranged in the external wall of the tubular sleeve 3, at its connection zone with ear 3a. It is therefore this washer 16 which rubs against the fixed ear, 1b1, when the tubular sleeve 3 pivots relative to said ear 1b1, while the washer 5, which is interposed between the two elements, 16 and 4b, integral in rotation of the tubular sleeve 3, ensures the locking of the rod 4a of the bolt in the nut 11, so as to avoid any loosening of said bolt, which would be due to vibrations and shocks to which the motor vehicle is exposed.

Une pièce d'extrémité, creuse, 6, par exemple en métal chromé extérieurement, est conformée de façon à pouvoir être engagée, par son extrémité gauche, la plus largement ouverte, par dessus le manchon tubulaire 3, de façon à venir recouvrir latéralement les oreilles 3a et 1b1, la tête 4b du boulon, l'extrémité opposée de sa tige 4a et l'écrou 11, comme le montre clairement la figure 2.A hollow end piece 6, for example made of chromed metal on the outside, is shaped so that it can be engaged, by its left end, the most widely open, over the tubular sleeve 3, so as to come laterally cover the ears 3a and 1b1, the head 4b of the bolt, the opposite end of its rod 4a and the nut 11, as clearly shown in FIG. 2.

On conçoit que l'on peut enfiler sur le manchon tubulaire 3 et les autres pièces mentionnées, différentec pièces creuses d'extrémité telles que 6, ayant les mêmes formes et dimensions, notamment intérieures, mais des finitions extérieures différentes, par exemple une finition noire mate au lieu d'une finition chromée brillante etc...It can be seen that it is possible to thread onto the tubular sleeve 3 and the other parts mentioned, different from the hollow end pieces such as 6, having the same shapes and dimensions, in particular internal, but with different external finishes, for example a black finish. matt instead of a bright chrome finish etc ...

Selon la présente invention, le bout 8a de l'antenne 8 (dont on a simplement représenté schématiquement la base) peut être fixé de façon rapidement libérable,à l'intérieur du manchon 3,par un accouplement à baîonnette, dont on va décrire une forme de réalisation possible, illustrée sur les figures 1 et 2:

  • Dans cette forme de réalisation, le manchon tubulaire 3 comporte,à l'une de ses deux extrémités, un alésage interne 3f, pour l'engagement de la base de l'antenne 8, qui est prolongé en direction de l'autre extrémité du manchon 3, par un alésage 3g, de plus petit diamètre, pour l'engagement du bout 8a de l'antenne. La paroi interne de l'alésage 3g du manchon 3 comporte deux rainures longitudinales, 12a et 12b, qui sont adaptées respectivement pour guider, lors de l'enfoncement du bout, 8a, de l'antenne 8, dans le manchon 3, deux saillies radiales, 13a et 13b, du bout 8a; ces deux rainures de guidage, 12a et 12b, débouchent respectivement, au niveau de la partie médiane du manchon 3, dans des encoches, 14a et 14b, également aménagées dans la paroi interne du manchon 3, et présentant chacune, dans la direction périphérique du manchon, une largeur (E sur la figure 4), notablement supérieure à la largeur(e) de la rainure longitudinale correspondante, 12a ou 12b. D'autre part, chacune des encoches 14a et 14b présente, dans son bord où débouche la rainure longitudinale correspondante, 12a ou 12b, un cran, 15a ou 15b, décalé par rapport à la rainure correspondante 12a ou 12b, dans la direction périphérique du manchon 3. Enfin, un ressort hélicoidal, 18, est accroché par l'une de ses deux spires extrêmes au bout 8a de l'antenne 8, ladite spire extrême du ressort 18 étant par exemple engagée dans une rainure annulaire 8b d'un prolongement axial, 8c du bout 8a de l'antenne 8; l'autre spire extrême du ressort hélicoïdal 18 prend appui sur une butée radiale, qui dans la forme de réalisation considérée, où l'alésage 3g du manchon 3 est borgne, est matérialisée par le fond 3h dudit alésage 3g.
According to the present invention, the tip 8a of the antenna 8 (the base of which has simply been shown schematically) can be fixed in a rapidly releasable manner, inside the sleeve 3, by a bayonet coupling, a description of which will be described. possible embodiment, illustrated in FIGS. 1 and 2:
  • In this embodiment, the tubular sleeve 3 has, at one of its two ends, an internal bore 3f, for the engagement of the base of the antenna 8, which is extended towards the other end of the sleeve 3, by a bore 3g, of smaller diameter, for engaging the tip 8a of the antenna. The internal wall of the bore 3g of the sleeve 3 has two longitudinal grooves, 12a and 12b, which are adapted respectively to guide, during the insertion of the tip, 8a, of the antenna 8, in the sleeve 3, two projections radial, 13a and 13b, from tip 8a; these two guide grooves, 12a and 12b, open respectively, at the middle part of the sleeve 3, in notches, 14a and 14b, also arranged in the internal wall of the sleeve 3, and each having, in the peripheral direction of the sleeve, a width (E in FIG. 4), notably greater than the width (e) of the corresponding longitudinal groove, 12a or 12b. On the other hand, each of the notches 14a and 14b has, in its edge where the corresponding longitudinal groove, 12a or 12b, opens, a notch, 15a or 15b, offset with respect to the corresponding groove 12a or 12b, in the peripheral direction of the sleeve 3. Finally, a helical spring, 18, is hooked by one of its two end turns to the end 8a of the antenna 8, said end turn of the spring 18 being for example engaged in an annular groove 8b of an axial extension, 8c of the end 8a of the antenna 8 ; the other extreme turn of the helical spring 18 is supported on a radial stop, which in the embodiment considered, where the bore 3g of the sleeve 3 is blind, is materialized by the bottom 3h of said bore 3g.

Le monteur de l'antenne communique tout d'abord à celle-ci une poussée axiale dans la direction de l'axe A du manchon 3, de façon que l'embout 8a traverse tout d'abord son alésage 3f; pour une position angulaire appropriée de l'antenne et de son bout 8a, ses saillies radiales, 13a et 13b, s'engagent alors respectivement dans les rainures longitudinales 12a et 12b, qui guident ensuite le bout 8a lorsqu'il traverse l'alésage 3g du manchon 3; lorsque les saillies radiales 13a et 13b du bout 8a ont pénétré respectivement dans les encoches 14a et 14b, la spire du ressort hélicoïdal 18,opposée au bout 8a,vient s'appliquer contre le fond 3h de l'alésage borgne 3g du manchon 3, et ledit bout 8a comprime légèrement ledit ressort 18 lorsque le mouvement axial du bout 8a se poursuit jusqu'à ce que les saillies radiales,13a et 13b,viennent buter contre les bords gauche (sur les figures 1 et 2) des encoches 14a et 14b. Le monteur doit alors faire tourner l'antenne 8 autour de l'axe A dans un sens approprié pour amener les saillies radiales 13a et 13b respectivement en regard des crans 15a et 15b des encoches 14a et 14b; il lâche alors l'antenne 8 et la détente du ressort hélicoïdal 18 a pour effet de communiquer à l'antenne 8 et à son bout 8a un mouvement axial, dirigé vers la droite des figures .! et 2 , et ayant pour effet d'engager les saillies radiales 13a et 13b dans les crans correspondants 15a et 15b, où elles demeurent bloquées. Pour enlever l'antenne du support, il suffit d'effectuer manuellement les mêmes opérations, dans l'ordre inverse de celui où elles viennent d'être décrites.The antenna fitter first communicates to the latter an axial thrust in the direction of the axis A of the sleeve 3, so that the end piece 8a firstly crosses its bore 3f; for an appropriate angular position of the antenna and its tip 8a, its radial projections, 13a and 13b, then engage respectively in the longitudinal grooves 12a and 12b, which then guide the tip 8a when it crosses the bore 3g sleeve 3; when the radial projections 13a and 13b of the tip 8a have respectively penetrated into the notches 14a and 14b, the turn of the helical spring 18, opposite the tip 8a, comes to rest against the bottom 3h of the blind bore 3g of the sleeve 3, and said tip 8a slightly compresses said spring 18 when the axial movement of the tip 8a continues until the radial projections, 13a and 13b, abut against the left edges (in FIGS. 1 and 2) of the notches 14a and 14b . The fitter must then rotate the antenna 8 around the axis A in an appropriate direction to bring the radial projections 13a and 13b respectively opposite the notches 15a and 15b of the notches 14a and 14b; it then releases the antenna 8 and the relaxation of the helical spring 18 has the effect of communicating to the antenna 8 and at its end 8a an axial movement, directed to the right of the figures.! and 2, and having the effect of engaging the radial projections 13a and 13b in the corresponding notches 15a and 15b, where they remain blocked. To remove the antenna from the support, just manually perform the same operations, in reverse order from the one they just described.

On comprend que, lorsque l'antenne 8 est montée sur le support d'antenne selon la présente invention, sa position angulaire autour de l'axe A du manchon 3, et par suite, son orientation par rapport au plan de pivotement dudit axe A est parfaitement déterminée par la coopération des saillies radiales 13a et 13b du bout 8a de l'antenne avec les crans 15a et 15b du manchon. Ceci est avantageux dans le cas d'une antenne qui ne présente pas une symétrie de révolution autour de son axe longitudinal, par exemple dans le cas d'un dipôle, cet avantage ne pouvant évidemment pas être obtenu dans le cas où le bout de l'antenne est simplement vissé dans le manchon 3.It is understood that, when the antenna 8 is mounted on the antenna support according to the present invention, its angular position around the axis A of the sleeve 3, and consequently, its orientation relative to the pivot plane of said axis A is perfectly determined by the cooperation of the radial projections 13a and 13b of the tip 8a of the antenna with the notches 15a and 15b of the sleeve. This is advantageous in the case of an antenna which does not have a symmetry of revolution about its longitudinal axis, for example in the case of a dipole, this advantage obviously being unable to be obtained in the case where the end of the the antenna is simply screwed into the sleeve 3.

Dans sa forme de réalisation illustrée sur les figures 1 et 2, le support d'antenne selon la présente invention présente également les caractéristiques suivantes, déjà decrites dans la demande de brevet français FPA 83 05 912 précité : l'embase 1a-1b du support est fixée sur la carrosserie par une tige filetée 2, qui les traverse de part en part, et qui est immobilisée en rotation par rapport à ladite embase, ainsi que par deux écrous, 2a et 2b, vissés respectivement sur les deux extrémités de la tige filetée; la partie médiane de la tige filetée 2 comporte une saillie radiale 2c, de contour polygonal, généralement hexagonal, qui peut coulisser avec la tige filetée 2 dans un évidement prismatique, de même section transversale, polygonale, aménagé dans l'embase 1a-1b; l'embase comporte un premier élément la,en matière plastique, applicable sur la carrosserie, et un second élément, 1b, métallique, applicable sur le premier élément la,et servant d'appui pour l'écrou correspondant, 2a; enfin, un cache 7, par exemple en matière synthétique moulée - non représenté sur la figure a - est monté de façon amovible sur l'embase 1a-1b de façon à recouvrir au moins l'extrémité supérieure de la tige filetée 2 et l'écrou 2a, vissé sur ladite extrémité supérieure.In its embodiment illustrated in Figures 1 and 2, the antenna support according to the present invention also has the following characteristics, already described in the aforementioned French patent application FPA 83 05 912: the base 1a-1b of the support is fixed to the bodywork by a threaded rod 2, which passes right through them, and which is immobilized in rotation relative to said base, as well as by two nuts, 2a and 2b, screwed respectively on the two ends of the rod threaded; the middle part of the threaded rod 2 has a radial projection 2c, of polygonal outline, generally hexagonal, which can slide with the threaded rod 2 in a prismatic recess, of the same cross section, polygonal, arranged in the base 1a-1b; the base comprises a first element 1a, made of plastic, applicable to the bodywork, and a second element, 1b, metallic, applicable to the first element 1a, and serving as a support for the corresponding nut, 2a; finally, a cover 7, for example of molded synthetic material - not shown in FIG. a - is removably mounted on the base 1a-1b so as to cover at least the upper end of the threaded rod 2 and the nut 2a, screwed onto said upper end.

La présente invention n'est pas limitée à la forme de réalisation précédemment décrite; elle englobe toutes ses variantes, dont quelques unes seulement vont être indiquées, à titre d'exemples non limitatifs.The present invention is not limited to the embodiment previously described; it encompasses all of its variants, only a few of which will be indicated, by way of nonlimiting examples.

Au lieu de comporter chacun une seule oreille, 1b1 pu 3a, constituant les ---- éléments d'un palier rotatif, l'embase 1b et/ou le manchon 3 pourrait chacun comporter deux oreilles,munies de trous alignés pour le passage de la tige 4a du boulon, comme décrit dans le brevet 8305912 .. La réalisation de l'accouplement à baïonnette entre le manchon 3 et le bout 8a de l'antenne 8 est également matière à option; le ressort hélicoïdal 18 pourrait être fixé au fond 3h de l'alésage borgne 3g du manchon 3, son autre extrémité coopérant directement avec l'extrémité,plane ou convenablement conformée, du bout 8a de l'antenne 8. Le ressort hélicoïdal 18 pourrait être remplacé par d'autres moyens élastiques de fonction équivalente. Il serait possible de munir le bout 8a de l'antenne 8 d'une seule saillie radiale telle que 13a, le manchon 3 étant lui- même pourvu intérieurement d'une seule rainure de guidage telle que 12a,débouchant dans une encoche telle que 14a.Dans une réalisation simplifiée, les crans tels que '15a, des encoches telles que 14a,pourraient être supprimés, de même que le ressort 18. Il serait alors préférable de prévoir des moyens produisant un freinage de la rotation de l'antenne 8 autour de l'axe A du manchon 3.Instead of each having a single ear, 1b1 pu 3a, constituting the ---- elements of a rotary bearing, the base 1b and / or the sleeve 3 could each have two ears, provided with holes aligned for the passage of the rod 4a of the bolt, as described in patent 8305912 .. The production of the bayonet coupling between the sleeve 3 and the tip 8a of the antenna 8 is also optional material; the helical spring 18 could be fixed to the bottom 3h of the blind bore 3g of the sleeve 3, its other end cooperating directly with the end, flat or suitably shaped, of the tip 8a of the antenna 8. The helical spring 18 could be replaced by other elastic means of equivalent function. It would be possible to provide the tip 8a of the antenna 8 with a single radial projection such as 13a, the sleeve 3 itself being provided internally with a single guide groove such as 12a, opening into a notch such as 14a .In a simplified embodiment, the notches such as' 15a, notches such as 14a, could be eliminated, as well as the spring 18. It would then be preferable to provide means producing a braking of the rotation of the antenna 8 around of axis A of sleeve 3.
