Description

La présente invention est relative à un dispositif anti-vol pour hisser ou amener automatiquement un pavillon sur une structure porteuse et notamment, quoique non exclusivement, sur un mât de support vertical.The present invention relates to an anti-theft device for hoisting or automatically bringing a flag on a supporting structure and in particular, although not exclusively, on a vertical support mast.

On connaît les solutions classiques pour hisser un pavillon à l'extrémité d'un mât, qui consistent le plus généralement à prévoir au sommet de ce dernier une poulie dans la gorge de laquelle passe une drisse, munie en bout d'une manille de fixation ou autre moyen analogue, sur un oeillet aménagé dans le coin supérieur du pavillon à hisser, cette drisse qui s'étend le long du mât étant le cas échéant renvoyée par une autre poulie montée à la base de ce dernier, pour être réunie à son extrémité opposée au coin inférieur du pavillon. Selon le sens de la traction exercée sur la drisse convenablement tendue entre ses deux poulies, il est ainsi possible de lever ou d'abaisser le pavillon le long du mât, la drisse formant ainsi une boucle continue.Conventional solutions are known for hoisting a flag at the end of a mast, which most generally consist in providing at the top of the latter a pulley in the groove of which passes a halyard, provided at the end with a fixing shackle or other similar means, on an eyelet fitted in the upper corner of the flag to be hoisted, this halyard which extends along the mast being optionally returned by another pulley mounted at the base of the latter, to be joined to its end opposite the lower corner of the pavilion. Depending on the direction of traction exerted on the halyard suitably stretched between its two pulleys, it is thus possible to raise or lower the flag along the mast, the halyard thus forming a continuous loop.

Or, ce sytème bien connu et qui présente une simplicité remarquable, comporte l'inconvénient que la drisse est à tout moment accessible à l'extérieur du mât et que le pavillon hissé sur ce dernier peut être amené, voire dérobé par un tiers mal intentionné, à qui il suffit de commander le mouvement de la drisse pour abaisser le pavillon avant de séparer les oeillets d'attache de celui-ci vis-à-vis des extrémités de cette drisse.However, this well known system, which has remarkable simplicity, has the disadvantage that the halyard is accessible at all times outside the mast and that the flag hoisted on the latter can be brought, or even stolen by a malicious third party , who just need to order the movement of the halyard to lower the roof before separating the eyelets from the latter vis-à-vis the ends of this halyard.

Pour pallier cet inconvénient, on a déjà prévu de disposer la drisse et en particulier les deux brins de celle-ci qui se déplacent en sens inverse dans la gorge de la poulie prévue à la partie supérieure du mât, à l'intérieur d'une rainure ou d'un logement aménagé à l'intérieur même de ce mât, la seconde poulie prévue à la base de celui-ci et les parties de la drisse qui s'enroulent sur cette dernière étant accessibles à travers une trappe prévue dans la surface du mât, cette trappe étant normalement fermée par une porte pivotante verrouillable et dont l'ouverture ne peut être commandée que par un utilisateur muni de la clé d'ouverture de cette trappe.To overcome this drawback, provision has already been made for arranging the halyard and in particular the two strands thereof which move in opposite directions in the groove of the pulley provided at the upper part of the mast, inside a groove or of a housing arranged inside the same mast, the second pulley provided at the base thereof and the parts of the halyard which are wound on the latter being accessible through a hatch provided in the surface of the mast, this hatch being normally closed by a lockable pivoting door and the opening of which can only be controlled by a user provided with the key for opening this hatch.

Mais cette solution n'apporte pas encore toute satisfaction, le déverrouillage non autorisé de la trappe ne présentant pas de difficultés généralement insurmontables, de telle sorte que la drisse puisse être commandée dans le sens qui amène le pavillon, celui-ci pouvant être alors facilement volé ou changé de façon intempestive.However, this solution is not yet entirely satisfactory, since the unauthorized unlocking of the hatch does not present generally insurmountable difficulties, so that the halyard can be controlled in the direction which brings the flag, which can then be easily stolen or accidentally changed.

La présente invention est relative à un dispositif pour hisser ou amener automatiquement un pavillon, une flamme, un drapeau etc... vis-à-vis d'une structure de support, qui élimine ces inconvénients, en évitant que les moyens qui réalisent l'élévation ou la descente du pavillon soient directement accessibles par un utilisateur situé au sol ou près de celui-ci, notamment à proximité immédiate de la base du mât portant ce pavillon ou plus généralement de la structure de support considérée.The present invention relates to a device for hoisting or automatically raising a flag, a flame, a flag, etc. with respect to a support structure, which eliminates these drawbacks, while avoiding that the means which realize the 'raising or lowering of the pavilion is directly accessible by a user located on the ground or near it, in particular in the immediate vicinity of the base of the mast carrying this pavilion or more generally of the support structure considered.

L'invention vise également un dispositif qui permet un changement aisé du pavillon par un utilisateur autorisé, notamment en cas de remplacement de ce pavillon par un autre, portant un emblème différent ou encore à la suite d'une détérioration ou d'une dégradation du pavillon initialement hissé, en particulier du fait du climat, du vent ou de toute autre cause extérieure.The invention also relates to a device which allows an easy change of the flag by an authorized user, in particular in the event of replacement of this flag by another, carrying a different emblem or further following a deterioration or a degradation of the flag initially hoisted, in particular because of the climate, the wind or any other external cause .

A cet effet, le dispositif considéré, pour hisser ou amener un pavillon ou analogue le long d'une structure de support, en particulier d'un mât vertical, au moyen d'une drisse coopérant avec une poulie d'entraînement montée à la partie supérieure de ce mât et dont une extrémité comporte un moyen de liaison avec le coin supérieur du pavillon, l'axe de la poulie d'entraînement étant commandé en rotation dans le sens qui provoque l'enroulement de la drisse pour hisser le pavillon ou son déroulement pour amener celui-ci, au moyen d'un motoréducteur mis sous tension par une source d'énergie électrique, se caractérise en ce que ladite source est commandée à travers un circuit de contrôle à partir d'un récepteur sensible à un rayonnement de préférence codé, issu d'un émetteur situé à distance, le récepteur et le motoréducteur de commande de la poulie d'entraînement de la drisse étant logés dans un boîtier de protection, disposé à la partie supérieure du mât vertical, ce boîtier comportant à sa partie dirigée vers le sol un fond muni d'une ouverture suffisante pour le passage de la drisse, s'enroulant ou se déroulant sur la poulie.To this end, the device considered, for hoisting or bringing a flag or the like along a support structure, in particular of a vertical mast, by means of a halyard cooperating with a drive pulley mounted to the part upper part of this mast and one end of which comprises a means of connection with the upper corner of the roof, the axis of the drive pulley being controlled in rotation in the direction which causes the halyard to wind up to hoist the roof or its unwinding to bring it, by means of a gearmotor energized by a source of electrical energy, is characterized in that said source is controlled through a control circuit from a receiver sensitive to radiation from preferably coded, from a transmitter located at a distance, the receiver and the gearmotor for controlling the halyard drive pulley being housed in a protective casing, located at the top of the u vertical mast, this box comprising at its part directed towards the ground a bottom provided with an opening sufficient for the passage of the halyard, winding or unwinding on the pulley.

Selon le cas, le rayonnement fourni par l'émetteur peut être un rayonnement électromagnétique dont la fréquence correspond à celui d'une onde radioélectrique, ou encore un rayonnement infrarouge, à ultra-sons ou autre, dont l'énergie est suffisante pour assurer une liaison sûre et fiable entre l'émetteur et le récepteur.Depending on the case, the radiation supplied by the transmitter can be electromagnetic radiation whose frequency corresponds to that of a radio wave, or even infrared, ultrasonic or other radiation, the energy of which is sufficient to ensure a safe and reliable connection between transmitter and receiver.

Avantageusement, la drisse comporte, au voisinage de son moyen de liaison avec le coin supérieur du pavillon, une butée adaptée à coopérer avec le contact de commande d'un relais placé dans le circuit de contrôle entre le récepteur et le motoréducteur, de telle sorte que la rotation de la poulie et par suite le mouvement de la drisse soit automatiquement interrompus lorsque le coin supérieur du pavillon est amené à proximité immédiate de l'extrémité supérieure du mât, sous le boîtier de protection.Advantageously, the halyard comprises, in the vicinity of its connecting means with the upper corner of the flag, a stop adapted to cooperate with the control contact of a relay placed in the control circuit between the receiver and the gearmotor, so that the rotation of the pulley and consequently the movement of the halyard is automatically interrupted when the upper corner of the roof is brought in the immediate vicinity of the upper end of the mast, under the protective housing.

De préférence, la butée portée par la drisse est constituée par un plot, serti ou autrement immobilisé sur la drisse, présentant un profil en partie conique de telle sorte que, consécutivement au déplacement de la drisse s'enroulant sur la poulie d'entraînement et au mouvement vers la partie supérieure du mât du plot, celui-ci vienne repousser l'extrémité du contact du relais, en ouvrant le circuit de contrôle.Preferably, the stop carried by the halyard is constituted by a stud, crimped or otherwise immobilized on the halyard, having a partially conical profile so that, following the displacement of the halyard winding on the drive pulley and when moving towards the upper part of the mast of the block, it comes to push the end of the contact of the relay, by opening the control circuit.

Selon une autre caractéristique du dispositif, le pavillon comporte un jonc rigide, engagé dans un ourlet délimité par une couture réalisée entre le coin supérieur du pavillon réuni à la drisse et le coin opposé, sur le côté du pavillon, afin de rigidifier celui-ci, notamment en fin de course lorsque le pavillon est disposé sous le boîtier de protection à l'extrémité supérieure du mât. Avantageusement, le jonc rigide se prolonge vers le haut, au-delà du pavillon, afin que son extrémité dépassante s'encastre dans un guide logé dans le boîtier.According to another characteristic of the device, the pavilion comprises a rigid rod, engaged in a hem delimited by a seam produced between the upper corner of the pavilion joined to the halyard and the opposite corner, on the side of the pavilion, in order to stiffen it , especially at the end of the race when the roof is placed under the protective housing at the upper end of the mast. Advantageously, the rigid rod extends upwards, beyond the pavilion, so that its projecting end is embedded in a guide housed in the housing.

De préférence mais de façon non nécessairement exclusive, l'extrémité opposée du jonc rigide est réunie à un organe de lest, destiné à maintenir le jonc vertical au voisinage du mât. Dans un mode de réalisation préféré, l'organe de lest est constitué par un collier, coulissant sur le mât avec un jeu suffisant, ce collier étant relié à un oeillet prévu à la base du jonc dans le coin correspondant du pavillon.Preferably but not necessarily exclusively, the opposite end of the rigid rod is joined to a ballast member, intended to keep the rod vertical in the vicinity of the mast. In a preferred embodiment, the ballast member is constituted by a collar, sliding on the mast with sufficient clearance, this collar being connected to an eyelet provided at the base of the rod in the corresponding corner of the flag.

Selon encore une autre caractéristique, le boîtier de protection comporte des moyens pour conférer à la source d'énergie réalisant la mise sous tension du motoréducteur, une autonomie de fonctionnement. Notamment, ces moyens peuvent être constitués par un jeu de cellules photovoltaïques, montées dans une des faces externes du boîtier, ces cellules étant réunies à une batterie à accumulation, apte à délivrer en permanence, de jour comme de nuit, la tension nécessaire à la commande du motoréducteur.According to yet another characteristic, the protective housing includes means for giving the power source carrying out the powering up of the geared motor, operating autonomy. In particular, these means can be constituted by a set of photovoltaic cells, mounted in one of the external faces of the housing, these cells being joined to a storage battery, capable of continuously delivering, day or night, the voltage necessary for the gear motor control.

Enfin, l'émetteur actionnant à distance le récepteur monté dans le boîtier de protection, comporte des moyens pour la commande continue ou par intermittence du motoréducteur, constitués notamment par deux boutons poussoirs, respectivement pour l'enroulement ou le déroulement de la drisse et dont le relâchement par l'opérateur arrête instanément la rotation de la poulie d'entraînement.Finally, the transmitter actuating the receiver remotely mounted in the protective housing, comprises means for the continuous or intermittent control of the gearmotor, constituted in particular by two push buttons, respectively for winding or unwinding the halyard and of which release by the operator instantly stops the rotation of the drive pulley.

D'autres caractéristiques d'un dispositif pour hisser ou amemer un pavillon par un ensemble de commande manoeuvré à distance, notamment sans intervention directe de l'opérateur sur la drisse à laquelle est réunie le pavillon, apparaîtront encore à travers la description qui suit d'exemples de réalisation, donnés à titre indicatif et non limitatif, en référence au dessin annexé sur lequel :

  • La Figure 1 est une vue schématique en élévation du dispositif considéré, permettant d'illustrer dans son ensemble les caractéristiques générales de celui-ci.
  • La Figure 2 est une vue en coupe transversale à plus grande échelle de l'extrémité supérieure du dispositif, représentant notamment le boîtier de protection des mécanismes et des moyens de commande permettant de hisser ou amener le pavillon.
  • La Figure 3 est une vue schématique illustrant une autre variante de réalisation.
Other characteristics of a device for hoisting or setting up a flag by a remote control assembly, in particular without direct operator intervention on the halyard with which the flag is joined, will become more apparent from the following description of '' exemplary embodiments, given by way of non-limiting example, with reference to the appended drawing in which:
  • Figure 1 is a schematic elevational view of the device considered, to illustrate as a whole the general characteristics of it.
  • Figure 2 is a cross-sectional view on a larger scale of the upper end of the device, in particular showing the protective housing of the mechanisms and control means for hoisting or bringing the flag.
  • Figure 3 is a schematic view illustrating another alternative embodiment.

Sur la Figure 1, la référence 1 désigne l'ensemble du dispositif, comportant notamment un mât vertical 2, dont l'extrémité inférieure est encastrée dans un bâti d'appui sur le sol 4, ce mât comportant à son extrémité supérieure un boîtier de protection 5 pour un mécanisme de commande conforme à l'invention et dont le détail sera explicité plus loin.In Figure 1, the reference 1 designates the entire device, comprising in particular a vertical mast 2, the lower end of which is embedded in a support frame on the ground 4, this mast comprising at its upper end a housing for protection 5 for a control mechanism according to the invention and the details of which will be explained below.

Notamment, ce mécanisme est prévu pour permettre selon le cas, de hisser ou d'mener le long du mât 2 un pavillon 6, dont un des coins supérieurs 7 est réuni à une drisse 8, assurant le déplacement de ce pavillon le long du mât, vers le haut ou vers le bas entre deux positions extrêmes, où le pavillon est schématiquement illustré sur la Figure en traits pointillés.In particular, this mechanism is provided to allow, as appropriate, to hoist or bring along the mast 2 a flag 6, one of the upper corners 7 of which is joined to a halyard 8, ensuring the displacement of this flag along the mast , up or down between two extreme positions, where the flag is schematically illustrated in the Figure in dotted lines.

Selon l'invention, le mécanisme monté dans le boîtier 5 est conçu pour être commandé à distance à partir d'un boîtier émetteur 9, tenu en main par un utilisateur 10 se trouvant sur le sol au voisinage de la base du mât, et qui transmet en direction d'un récepteur 25 (Figure 2), logé dans le boîtier, un rayonnement approprié, représenté sur le dessin par les flèches en zig-zag 11.According to the invention, the mechanism mounted in the housing 5 is designed to be controlled remotely from a transmitter housing 9, held in hand by a user 10 located on the ground in the vicinity of the base of the mast, and which transmits towards a receiver 25 (Figure 2), housed in the housing, appropriate radiation, represented in the drawing by the zig-zag arrows 11.

La Figure 2 illustre avec plus de détails un mode de réalisation particulier du dispositif considéré et notamment de l'ensemble des organes montés à l'intérieur du boîtier 5, ce dernier étant immobilisé à l'extrémité supérieure 12 du mât 2 par des colliers de serrage 13 ou analogues.Figure 2 illustrates in more detail a particular embodiment of the device considered and in particular of all of the members mounted inside the housing 5, the latter being immobilized at the upper end 12 of the mast 2 by collars of clamping 13 or the like.

A l'intérieur du boîtier 5 est ainsi disposé, sur une plate-forme de support 14, une batterie à accumulation 15, avantageusement reliée à des cellules photovoltaïques 16, montées dans une des faces extérieures 17 du boîtier, celui-ci étant fixé sur le mât 2 avec une orientation convenable par rapport à l'axe de ce dernier pour que les cellules 16 soient préférentiellement dirigées au sud, en direction du soleil. Ces dispositions permettent notamment de fournir à la batterie 15 une énergie suffisante pour assurer sa charge le jour, et permettre un fonctionnement en tout temps, la batterie se déchargeant le cas échéant la nuit si elle est sollicitée.Inside the housing 5 is thus arranged, on a support platform 14, an accumulation battery 15, advantageously connected to photovoltaic cells 16, mounted in one of the outer faces 17 of the housing, the latter being fixed to the mast 2 with a suitable orientation relative to the axis of the latter so that the cells 16 are preferably directed south, towards the sun. These provisions make it possible in particular to supply the battery 15 with sufficient energy to ensure its charge during the day, and allow operation at all times, the battery discharging if necessary at night if it is used.

Dans le boîtier 5 est également montée une poulie d'entraînement 18, dans la gorge de laquelle s'enroule ou se déroule selon le cas la drisse 8, permettant de hisser ou d'amener le pavillon 6. Cette poulie comporte un axe de rotation 19 en prise avec un réducteur 10, lui-même entraîné par l'arbre de sortie (non représenté) d'un moteur 21, dont la mise sous tension est assurée à partir de la batterie 15. Les bornes d'alimentation du moteur 21 sont disposées dans un circuit électrique imprimé sur une plaquette 22, immobilisée par des pattes 23, contre l'un des côtés 24 du boîtier 5 à l'intérieur de celui-ci, ce circuit étant lui-même raccordé à un ensemble récepteur 25, muni d'une antenne 26, apte à capter le rayonnement 11 émis par l'émetteur 9. Le boîtier 5 est ouvert à sa partie inférieure 5a ou comporte un fond 5a muni au moins d'une ouverture suffisante 5b pour permettre le passage de la drisse 8 lors de ses mouvements de montée ou de descente du pavillon 6. De façon particulièrement avantageuse, le signal émis est codé de manière à éviter une mise en route non commandée et notamment non autorisée du moteur 21, ce signal provenant de l'émetteur 9 qui est calé sur la même fréquence que le récepteur.In the housing 5 is also mounted a drive pulley 18, in the groove of which the halyard 8 is wound up or unwound, allowing the flag 6 to be hoisted or brought up. This pulley comprises an axis of rotation 19 engaged with a reduction gear 10, itself driven by the output shaft (not shown) of a motor 21, the power supply of which is ensured from the battery 15. The power supply terminals of the motor 21 are arranged in an electrical circuit printed on a wafer 22, immobilized by lugs 23, against one of the sides 24 of the housing 5 inside thereof, this circuit itself being connected to a receiver assembly 25, provided with an antenna 26, capable of picking up the radiation 11 emitted by the emitter 9. The box 5 is open at its lower part 5a or comprises a bottom 5a provided with at least a sufficient opening 5b to allow the passage of the halyard 8 during its movements of raising or lowering of the pa villon 6. In a particularly advantageous manner, the signal transmitted is coded so as to avoid an uncontrolled and in particular unauthorized start-up of the motor 21, this signal coming from the transmitter 9 which is calibrated on the same frequency as the receiver.

Le boîtier émetteur 9 comporte à son tour, éventuellement une antenne 27, un interrupteur marche-arrêt 28 pour la mise sous tension ou hors tension de ses circuits internes et deux boutons poussoirs, respectivement 29 et 30, ceux-ci étant agencés de telle sorte que, selon que l'un ou l'autre est actionné, le signal émis par l'émetteur, reçu par le récepteur 25 commande le moteur 21 et par suite la poulie 18 dans le sens qui enroule ou déroule la drisse 8, pour monter ou descendre le pavillon 6.The transmitter unit 9 in turn comprises, optionally an antenna 27, an on-off switch 28 for switching on or off its internal circuits and two push buttons, respectively 29 and 30, these being arranged so that, depending on whether one or the other is actuated, the signal transmitted by the transmitter, received by the receiver 25 controls the motor 21 and by then the pulley 18 in the direction that winds or unrolls the halyard 8, to raise or lower the roof 6.

L'équipement du dispositif se complète au moyen d'un jonc rigide 31 logé dans un ourlet 32 du pavillon et qui maintient le bord de celui-ci sensiblement parallèle au mât 2, quelle que soit la position du pavillon le long de celui-ci. Dans son coin supérieur, le pavillon comporte un oeillet 33 pour permettre la liaison avec la drisse 8 et à son coin inférieur, à l'extrémité du jonc 31, un oeillet analogue 34, permettant de réunir au pavillon un collier 35, lestant convenablement le jonc dans son déplacement le long du mât. De préférence, ce collier est réalisé sous la forme d'une chaîne 36, montée dans une enveloppe en plastique 37, une telle réalisation n'ayant toutefois qu'un caractère optionnel mais pouvant être remplacée par toute autre ayant un effet équivalent.The equipment of the device is completed by means of a rigid rod 31 housed in a hem 32 of the flag and which keeps the edge of the latter substantially parallel to the mast 2, whatever the position of the flag along the latter. . In its upper corner, the pavilion has an eyelet 33 to allow connection with the halyard 8 and at its lower corner, at the end of the rod 31, a similar eyelet 34, making it possible to join the pavilion a collar 35, properly ballasting the rod in its movement along the mast. Preferably, this collar is produced in the form of a chain 36, mounted in a plastic envelope 37, such an embodiment having however only an optional character but being able to be replaced by any other having an equivalent effect.

Avantageusement, le jonc 31 comporte une partie dépassante, dirigée vers le haut à partir de l'oeillet 33, constituée notamment par une baguette 38, faisant de préférence directement partie du jonc et à l'extrémité de laquelle est prévue un moyen d'attache 39 avec l'extrémité de la drisse, du genre d'une manille, d'un crochet ou d'un système équivalent. En variante, l'extrémité de la drisse peut être directement réuni à l'oeillet 33. Lorsque le pavillon est en position haute, la baguette 38 s'engage notamment dans un guide 38a monté à l'intérieur du boîtier 5 et dans lequel coulisse la drisse 8, de manière à immobiliser la baguette et le jonc 31 dont elle est solidaire.Advantageously, the rod 31 has an protruding part, directed upwards from the eyelet 33, constituted in particular by a rod 38, preferably forming directly part of the rod and at the end of which is provided a means of attachment 39 with the end of the halyard, such as a shackle, a hook or an equivalent system. As a variant, the end of the halyard can be directly joined to the eyelet 33. When the roof is in the high position, the strip 38 engages in particular in a guide 38a mounted inside the housing 5 and in which slides the halyard 8, so as to immobilize the rod and the rod 31 of which it is integral.

Sur la baguette 38 est par ailleurs monté un plot 40 formant organe de butée, comportant une partie conique 41 apte à venir agir sur une roulette 42 montée en bout d'un bras basculant 43 ou contact d'actionnement d'un relais 44, ce bras étant rappelé par un ressort 45, de telle sorte qu'il ferme en permanence le circuit du moteur 21 sauf lorsque le bras basculant 43 est actionné par le plot 40, l'ouverture du circuit qui en résulte rendant le moteur inactif dans le sens de l'enroulement de la drisse, le pavillon étant alors en position haute maximale.On the rod 38 is also mounted a stud 40 forming a stop member, comprising a conical part 41 capable of acting on a roller 42 mounted at the end of a rocking arm 43 or actuating contact of a relay 44, this arm being returned by a spring 45, so that it permanently closes the circuit of the motor 21 except when the rocking arm 43 is actuated by the stud 40, the opening of the resulting circuit making the motor inactive in the direction of the halyard winding, the roof then being in the maximum high position.

On réalise aini un dispositif de commande pour hisser ou amener un pavillon permettant une sécurité maximale, seul pouvant assurer la manoeuvre du pavillon l'utilisateur disposant de l'émetteur de commande, l'extrémité supérieure du mât étant généralement inaccessible directement. Avantageusement, le signal de commande issu de l'émetteur est un signal radioélectrique, de fréquence appropriée, sur laquelle est calée la fréquence du récepteur ; en variante, le rayonnement issu de l'émetteur pourrait être un rayonnement infrarouge ou à ultra-sons.There is thus produced a control device for hoisting or bringing up a flag allowing maximum security, only being able to operate the flag the user having the control transmitter, the upper end of the mast being generally inaccessible directly. Advantageously, the control signal from the transmitter is a radio signal, of appropriate frequency, on which the frequency of the receiver is calibrated; alternatively, the radiation from the transmitter could be infrared or ultrasonic radiation.

Comme déjà souligné, le signal de commande issu de l'émetteur est préférentiellement un signal codé que le récepteur, calé sur la même fréquence, décode avant d'actionner le moteur entraînant la poulie de la drisse, l'émission du signal ne se produisant qu'après que l'utilisateur ait entré dans l'émetteur et le récepteur le code autorisé.As already emphasized, the control signal from the transmitter is preferably a coded signal that the receiver, calibrated on the same frequency, decodes before actuating the motor driving the halyard pulley, the emission of the signal not occurring only after the user has entered the authorized code in the transmitter and receiver.

Dans tous les cas, l'émetteur est prévu de telle sorte que les boutons de commande qu'il comporte puissent manoeuvrer la drisse, soit en continu, soit par impulsions successives, en permettant à tout moment d'arrêter le déplacement du pavillon dans un sens ou dans l'autre. Le plot porté par la drisse arrête dans tous les cas le mouvement d'enroulement de celle-ci sur sa poulie en fin de course haute du pavillon. Le cas échéant, une disposition analogue peut être prévue en fin de course basse, lorsque le pavillon est complètement amené.In all cases, the transmitter is provided in such a way that the control buttons which it comprises can maneuver the halyard, either continuously or by successive pulses, allowing at any time to stop the movement of the roof in a one way or the other. The stud carried by the halyard stops in all cases the winding movement of the latter on its pulley at the end of the flag's upper stroke. If necessary, a similar arrangement can be provided at the end of the lower stroke, when the roof is completely brought up.

Le dispositif constitue enfin un ensemble entièrement autonome, grâce à la batterie et aux cellules solaires qu'il comporte.Finally, the device constitutes a completely autonomous assembly, thanks to the battery and the solar cells which it comprises.

Bien entendu, il va de soi que l'invention ne se limite pas aux exemples de réalisation plus spécialement décrits et représentés ci-dessus ; elle en embrasse au contraire toutes les variantes. En particulier, il est bien évident que le dispositif peut être adapté sur n'importe quelle structure de support pour le pavillon et non pas nécessairement sur un mât vertical. La Figure 3 illustre ainsi schématiquement une variante dans laquelle le boîtier 5 est monté sur la paroi d'une façade d'un immeuble 46 ou analogue, en permettant de façon identique de hisser ou d'amener un pavillon 6, par une commande entièrement autonome et exercée à distance.Of course, it goes without saying that the invention is not limited to the examples of embodiment more particularly described and represented above; on the contrary, it embraces all its variants. In particular, it is obvious that the device can be adapted on any support structure for the roof and not necessarily on a vertical mast. Figure 3 thus schematically illustrates a variant in which the housing 5 is mounted on the wall of a facade of a building 46 or the like, by allowing an identical way to hoist or bring a flag 6, by a completely autonomous control and exercised at a distance.
