Description

Principalement utilisées pour la radio téléphonie, les antennes radio sont généralement de forme parallélépipédiques et doivent être réglées en azimut et en verticalité. Habituellement le réglage en azimut s'obtient par rotation autour d'un axe vertical tubulaire, la liaison avec ce tube s'effectuant par pincement. Le fait de desserrer les mâchoires pour le faire tourner lui permet également de glisser sur le tube et par conséquent de rendre la manoeuvre délicate. Le réglage en verticalité s'effectuant à partir de compas dont une des branches est pincée sur le tube, l'autre solidaire du support antenne. La variation angulaire des deux branches éloigne ou rapproche le haut de l'antenne du mât central et par conséquent modifie l'angle de l'antenne par rapport à la verticale. Mainly used for radio telephony, radio antennas are generally rectangular in shape and must be adjusted in azimuth and verticality. Usually the azimuth adjustment is obtained by rotation around a vertical tubular axis, the connection with this tube being effected by pinching. Loosing the jaws to rotate it also allows it to slide on the tube and therefore make the operation delicate. The vertical adjustment is made from compasses, one of the branches of which is pinched on the tube, the other secured to the antenna support. The angular variation of the two branches moves the top of the antenna away from or closer to the central mast and consequently modifies the angle of the antenna with respect to the vertical.
De plus, la hauteur nécessaire pour faire fonctionner l'antenne par rapport à la plate forme étant généralement située entre 3 et 4 m, il est souvent nécessaire de grimper sur le mât support pour accéder aux réglages, ce qui est dangereux (la plupart des antennes étant situées sur le bord des toits terrasse d'immeubles). De plus les systèmes d'accrochage de sécurité pénalisent les résistances mécaniques des supports. In addition, the height necessary to operate the antenna relative to the platform is generally between 3 and 4 m, it is often necessary to climb on the support mast to access the settings, which is dangerous (most antennas being located on the edge of building roofs). In addition, the safety attachment systems penalize the mechanical resistance of the supports.
Une des réponses à ce problème de hauteur a été apportée en basculant le mât (ce dernier étant articulé autour de son centre de gravité) mais ce principe présente deux inconvénients majeurs : difficulté de régler précisément l'antenne alors que celle-ci est à l'horizontal, nécessité d'une grande surface au sol sans obstacles à l'arrière du mât pour le basculement. L'équilibrage de la portée articulée s'effectue par apport de masse d'acier. One of the answers to this problem of height was brought by tilting the mast (the latter being articulated around its center of gravity) but this principle has two major drawbacks: difficulty in precisely adjusting the antenna while it is at 'horizontal, need for a large floor area without obstacles behind the mast for tilting. The articulated span is balanced by adding steel mass.
La présente invention permet de palier à ces différents défauts, le mât (1) est fixe (pas de nécessité de place libre derrière le mât), les réglages sont indépendants (pas de risque de dérégler un paramètre pour régler l'autre). Enfin, la mise en place de l'antenne sur le mât et ses réglages s'effectuent à partir du sol (sécurité des personnes). The present invention overcomes these various faults, the mast (1) is fixed (no need for free space behind the mast), the settings are independent (no risk of disrupting one parameter to adjust the other). Finally, the installation of the antenna on the mast and its adjustments are made from the ground (personal safety).
L'invention comporte un mât (1) (tubulaire de préférence mais qui peut être réalisé autrement) (en treillis par exemple) en tête de mât sera fixé un anneau (2) ; le diamètre minimum de cet anneau permettra de recevoir jusqu'à trois supports antennes (3) l'augmentation de son diamètre ne pénalise pas le fonctionnement mais seulement l'aspect visuel du produit. Solidaire du mât mais situé sous l'anneau de tête sera situé un profilé circulaire mécano soudé (4), cet anneau permettra la fixation sur 3600 des bras de réglage du tilt (5 figure 1). The invention comprises a mast (1) (preferably tubular but which can be made otherwise) (in trellis for example) at the top of the mast will be fixed a ring (2); the minimum diameter of this ring will accommodate up to three antenna supports (3) increasing its diameter does not penalize the operation but only the visual aspect of the product. Solid with the mast but located under the head ring will be located a mechanically welded circular profile (4), this ring will allow the fixing on 3600 of the tilt adjustment arms (5 figure 1).
Le bras de réglage du tilt (5) sera préférentiellement constitué de profilés parallèles ménageant en leur centre un espace permettant le passage du tirant (6). The tilt adjustment arm (5) will preferably consist of parallel profiles providing in their center a space allowing the passage of the tie rod (6).

Les antennes (15) étant de différentes provenances, leurs fixations comportent des entr'axes différents, c'est la raison pour laquelle la fixation de l'antenne sur le support antenne (3) est réalisé par l'intermédiaire de lumières. Le support antenne (3) est constitué d'un profilé métallique en partie supérieure duquel sont fixés deux crochets (7) dont la forme est adaptée à l'anneau supérieur (2). Les crochets dans une version préférentielle de l'invention ont une forme qui ne permet pas leur décrochement en position inclinée ou verticale, il faut s'éloigner de 100 environ de la verticale (côté opposé au mât) pour permettre de décrocher le support antenne (7) de l'anneau (2). Afin de faciliter les opérations de manutention des encoches (16) seront réalisées dans l'anneau (2) ; ces encoches seront positionnées de telle sorte qu'elles se trouvent au même angle que la patte d'accrochage du palan (17 figure 1). The antennas (15) being from different sources, their attachments have different spacings, this is the reason why the attachment of the antenna to the antenna support (3) is carried out by means of lights. The antenna support (3) consists of a metal profile in the upper part of which are fixed two hooks (7) whose shape is adapted to the upper ring (2). The hooks in a preferred version of the invention have a shape which does not allow them to hang in an inclined or vertical position, it is necessary to move away from about 100 from the vertical (side opposite to the mast) to allow the antenna support to be detached ( 7) of the ring (2). In order to facilitate the handling operations of the notches (16) will be carried out in the ring (2); these notches will be positioned so that they are at the same angle as the hooking lug of the hoist (17 figure 1).
En partie inférieure du profil (3) sera placé le tirant (6) dont l'effort sera repris par le bras (5). Afin de limiter le couple de tension, un indicateur de traction (9) sera placé sur le tirant (6) (entre l'écrou (11) et le bras (5 figure 2)). Cet indicateur sera constitué d'un ressort de compression (8) situé dans deux tubes coulissants (9). Un repère tracé sur l'un des deux cylindres indiquera la compression du ressort et par conséquent l'effort de traction appliqué à la pièce (3). In the lower part of the profile (3) will be placed the tie rod (6) whose effort will be taken up by the arm (5). In order to limit the tension torque, a traction indicator (9) will be placed on the tie rod (6) (between the nut (11) and the arm (5 figure 2)). This indicator will consist of a compression spring (8) located in two sliding tubes (9). A mark drawn on one of the two cylinders will indicate the compression of the spring and therefore the tensile force applied to the part (3).
Dans une version préférentielle de l'invention (planche 3/3), un palan multi brins pourra être accroché, à l'une de ces extrémités, sur un support situé en partie haute du mât (17) par l'intermédiaire d'une rallonge et à l'autre extrémité sur le support d'antenne (3). La rallonge, dont un logement sera prévu sur le dispositif sera équipée d'un crochet, qui permettra d'accrocher et de décrocher le palan de son support en t^te de mât (17). L'un des deux crochet du palan sera fixé sur le support antenne, la traction depuis le bas sur le palan (18 figure 4) hissera l'antenne jusqu'à ce que l'accrochage des crochets supports antennes (7) s'effectue sur l'anneau (2) dans les encoches réalisées dans la couronne (16 figure 1). In a preferred version of the invention (plate 3/3), a multi-strand hoist may be hung, at one of these ends, on a support located in the upper part of the mast (17) by means of a extension and at the other end on the antenna support (3). The extension, of which a housing will be provided on the device, will be fitted with a hook, which will allow the hoist to be hooked and unhooked from its support at the head of the mast (17). One of the two hooks of the hoist will be fixed on the antenna support, pulling from below on the hoist (18 figure 4) will hoist the antenna until the hooking of the antenna support hooks (7) is carried out. on the ring (2) in the notches made in the crown (16 figure 1).
Pour permettre le réglage en azimut de l'antenne, il suffira de desserrer le tirant (6) et le curseur (12) et de débloquer le bras (5) à l'aide de la vis (10 figure 3). Ensuite il faudra déplacer le support d'antenne (en soulevant légèrement l'ensemble) le long de l'anneau jusqu'à l'azimut désiré, enfin, ramener le bras (5) par rotation jusqu'à ce que le tirant (6) soit centré dans le bras (5), puis immobiliser le bras par le boulon (10 figure 3) et assurer le blocage du support par tension sur le tirant (6), serrage de l'écrou (11). Pour le réglage par rapport à la verticale (tilt) desserrer l'écrou (11 figure 2), desserrer l'étrier de verrouillage (12 figure 3), faire coulisser le support antenne (3) dans le support (5) jusqu'à l'angle désiré, un réglet fixe (13) permet d'obtenir une aide efficace au réglage. Pour figer le réglage, remettre le support d'antenne sous tension à l'aide de l'écrou (11), rebloquer l'étrier (12) en serrant les deux vis (14 figure 3). To allow the azimuth adjustment of the antenna, it will suffice to loosen the tie rod (6) and the slider (12) and unlock the arm (5) using the screw (10 figure 3). Then it will be necessary to move the antenna support (slightly lifting the assembly) along the ring to the desired azimuth, finally, bring the arm (5) by rotation until the tie (6 ) is centered in the arm (5), then immobilize the arm by the bolt (10 figure 3) and ensure the blocking of the support by tension on the tie rod (6), tightening of the nut (11). To adjust with respect to the vertical (tilt) loosen the nut (11 figure 2), loosen the locking clip (12 figure 3), slide the antenna support (3) in the support (5) until the desired angle, a fixed ruler (13) provides effective adjustment assistance. To freeze the adjustment, re-energize the antenna support using the nut (11), re-lock the bracket (12) by tightening the two screws (14 figure 3).
L'antenne est alors prête pour l'utilisation.The antenna is then ready for use.
