Description

La présente invention concerne les dispositifs ou systèmes d'affichage, notamment d'affichage publicitaire.The present invention relates to display devices or systems, in particular advertising displays.

Conformément au document DE-A-3 703 150, on connaît un dispositif d'affichage présentant de manière générale un axe de symétrie vertical, comportant un support fixe constitué par deux cadres horizontaux de profil hexagonal, montés l'un au-dessus de l'autre en vis-à-vis, et six panneaux d'affichage, distribués selon la périphérie du support, et disposés chacun verticalement dans une ouverture rectangulaire ménagée par deux côtés superposés du support, et parallèlement à l'axe de symétrie. Chaque panneau est monté en rotation recto-verso sur le support, autour d'un axe individuel de rotation, parallèle à l'axe de symétrie, et disposé selon un côté vertical de l'ouverture rectangulaire obturée par ledit panneau. Un plateau inférieur rotatif comportant six gouttières de guidage, coopérant chacune avec un téton prévu au-dessous du côté inférieur de chaque panneau, permet d'entraîner en rotation lesdits panneaux, autour de leurs axes individuels et respectifs de rotation, tout en synchronisant leurs rotations respectives, pour les faire pivoter en même temps dans le même sens recto-verso, ou verso-recto.According to document DE-A-3 703 150, a display device is known which generally has a vertical axis of symmetry, comprising a fixed support constituted by two horizontal frames of hexagonal profile, one mounted above the 'other vis-à-vis, and six display panels, distributed along the periphery of the support, and each arranged vertically in a rectangular opening formed by two superposed sides of the support, and parallel to the axis of symmetry. Each panel is mounted in recto-verso rotation on the support, around an individual axis of rotation, parallel to the axis of symmetry, and arranged along a vertical side of the rectangular opening closed by said panel. A rotary lower plate comprising six guide gutters, each cooperating with a stud provided below the lower side of each panel, enables said panels to rotate, around their individual and respective axes of rotation, while synchronizing their rotations to rotate them at the same time in the same duplex direction, or verso-recto.

Selon ce document, la rotation de chaque panneau s'effectue à l'intérieur du support, et en balayant une surface cylindrique de rayon égal à la largeur complète dudit panneau. En conséquence, le volume cylindrique circonscrivant le support de section horizontale hexagonale doit avoir un diamètre au moins égal à deux fois la largeur d'un panneau. Pour un encombrement ou volume donné du dispositif d'affichage, ceci oblige à prévoir des panneaux de largeur relativement limitée, ou pour des panneaux d'une largeur donnée, ceci oblige à envisager un dispositif d'affichage d'encombrement relativement important.According to this document, the rotation of each panel takes place inside the support, and by scanning a cylindrical surface of radius equal to the full width of said panel. Consequently, the cylindrical volume circumscribing the support of hexagonal horizontal section must have a diameter at least equal to twice the width of a panel. For a given size or volume of the display device, this requires the provision of panels of relatively limited width, or for panels of a given width, this requires considering a relatively large size display device.

Si un tel inconvénient peut être toléré pour un dispositif d'affichage de faible encombrement, tel que ceux rencontrés dans la vitrine d'un magasin, il est par contre rédhibitoire pour un dispositif d'affichage de taille beaucoup plus importante, tel que ceux utilisés à des fins publicitaires en plein air, comportant par exemple des panneaux d'affichage ayant chacun une surface proche d'une dizaine de mètres carrés.If such a drawback can be tolerated for a display device with a small footprint, such as those encountered in the window of a store, it is however unacceptable for a display device of much larger size, such as those used. for outdoor advertising purposes, for example comprising display panels each having an area close to ten square meters.

La présente invention a donc pour objet une solution, et plus précisément un arrangement particulier des panneaux par rapport à leur support, permettant de limiter dans des proportions importantes l'encombrement en volume, et en particulier selon sa section horizontale, d'un dispositif d'affichage, et ce à partir d'une taille donnée des panneaux d'affichage, notamment d'une largeur donnée de ces derniers.The present invention therefore relates to a solution, and more specifically a particular arrangement of the panels with respect to their support, making it possible to limit in considerable proportions the bulk in volume, and in particular according to its horizontal section, of a display device, and this from a given size of the display panels, in particular a given width of the latter.

Selon la présente invention, en combinaison :

  • l'axe individuel de rotation de chaque panneau d'affichage est décalé par rapport au point médian selon la largeur dudit panneau, de manière à ménager dans ce dernier une section relativement étroite et une section relativement large , disposées de part et d'autre dudit axe de rotation individuel
  • l'intervalle séparant l'axe du support et chaque axe individuel de rotation d'un panneau est ajusté pour permettre uniquement le passage en rotation de la section étroite des panneaux d'affichage, dans le sens de rotation assurant l'inversion recto-verso ou verso-recto d'un panneau donné.
According to the present invention, in combination:
  • the individual axis of rotation of each display panel is offset from the midpoint along the width of said panel, so as to provide therein a relatively narrow section and a relatively wide section, arranged on either side of said panel individual axis of rotation
  • the interval between the axis of the support and each individual axis of rotation of a panel is adjusted to allow only the passage in rotation of the narrow section of the display panels, in the direction of rotation ensuring the double-sided reversal or back and front of a given panel.

La solution selon l'invention permet de limiter le volume opératoire du dispositif d'affichage, à proportion de la section étroite choisie ou retenue pour chaque panneau, à partir de la distance séparant l'axe de symétrie du support par rapport au point ou axe de symétrie médian de chaque dit panneau.The solution according to the invention makes it possible to limit the operating volume of the display device, in proportion to the narrow section chosen or retained for each panel, from the distance separating the axis of symmetry of the support from the point or axis of median symmetry of each said panel.

Ainsi, pour un dispositif d'affichage comportant trois panneaux rectangulaires rotatifs recto-verso, de hauteur égale à 3,20 m, et de largeur égale à 4,20 m :

  • antérieurement à l'invention, c'est-à-dire lorsque l'axe de rotation de chaque panneau coïncide avec son axe de symétrie selon la largeur, le support présentait un rayon hors-tout de 3 m 34
  • selon l'invention, c'est-à-dire lorsque l'axe de rotation de chaque panneau est décalé par rapport à l'axe de symétrie selon la largeur, le support présente un rayon hors-tout de 2 m 71.
Thus, for a display device comprising three rectangular recto-verso rotary panels, of height equal to 3.20 m, and of width equal to 4.20 m:
  • prior to the invention, that is to say when the axis of rotation of each panel coincides with its axis of symmetry along the width, the support had an overall radius of 3 m 34
  • according to the invention, that is to say when the axis of rotation of each panel is offset from the axis of symmetry along the width, the support has an overall radius of 2 m 71.

Le gain de place obtenu selon l'invention apparaît donc significatif.The space saving obtained according to the invention therefore appears significant.

La solution selon la présente invention apparaît particulièrement bien adaptée au cas où le support équipé des différents panneaux rotatifs est monté de manière tournante, c'est-à-dire en rotation, autour de l'axe de symétrie dudit support, par rapport à un pied ou socle fixe, car dans ce cas c'est précisément le volume cylindrique circonscrivant le support qui fixe l'encombrement du dispositif d'affichage.The solution according to the present invention appears to be particularly well suited to the case where the support equipped with the various rotary panels is mounted in a rotary manner, that is to say in rotation, about the axis of symmetry of said support, with respect to a foot or fixed base, because in this case it is precisely the cylindrical volume circumscribing the support which fixes the size of the display device.

Et la solution selon l'invention est encore plus adaptée au cas où le support tournant est monté au sommet d'un mât, et autour de l'axe de ce dernier, car dans ce cas, la rotation individuelle recto-verso ou verso-recto des panneaux peut s'effectuer librement, en ce qui concerne le débattement extérieur de la section large desdits panneaux.And the solution according to the invention is even more suited to the case where the rotating support is mounted at the top of a mast, and around the axis of the latter, because in this case, the individual recto-verso or verso-recto rotation of the panels can be carried out freely, as regards the external clearance of the wide section of said panels.

Par "largeur" et "hauteur" du panneau, quelle que soit la forme de ce dernier, on entend respectivement la dimension dudit panneau orthogonale à l'axe de symétrie du support, et la dimension dudit panneau parallèle audit axe.By "width" and "height" of the panel, whatever the shape of the latter, is meant respectively the dimension of said panel orthogonal to the axis of symmetry of the support, and the dimension of said panel parallel to said axis.

Conformément à la présente invention, un dispositif d'affichage selon l'invention comporte de manière principale :

  • un pied ou mât 1, fixé sur le sol par une embase 60 appropriée, ce pied comportant deux sections, l'une inférieure 1a de diamètre relativement important, et l'autre supérieure 1b de diamètre plus faible, servant de tourillon,
  • un support tournant 2, monté en rotation sur la partie supérieure 1b du pied 1, autour de l'axe de ce dernier, ce support comportant deux flasques 14 et 15 d'extension radiale, l'un supérieur 15 et l'autre inférieur 14,
  • trois panneaux d'affichage 4, 5 et 6, disposés en triangle autour de l'axe 3, par conséquent distribués de manière régulière selon la trajectoire périphérique du support 2 ; chaque panneau 4, 5 ou 6 est monté en rotation sur le support 2, entre les deux flasques 14 et 15, disposés de part et d'autre dudit panneau selon sa hauteur.
  • un moyen d'entraînement 10 en rotation de chaque panneau d'affichage, 4, 5, ou 6.
According to the present invention, a display device according to the invention mainly comprises:
  • a foot or mast 1, fixed to the ground by an appropriate base 60, this foot comprising two sections, one lower 1a of relatively large diameter, and the other upper 1b of smaller diameter, serving as a journal,
  • a rotating support 2, mounted in rotation on the upper part 1b of the foot 1, around the axis of the latter, this support comprising two flanges 14 and 15 of radial extension, one upper 15 and the other lower 14 ,
  • three display panels 4, 5 and 6, arranged in a triangle around the axis 3, therefore distributed regularly along the peripheral trajectory of the support 2; each panel 4, 5 or 6 is rotatably mounted on the support 2, between the two flanges 14 and 15, arranged on either side of said panel according to its height.
  • a drive means 10 for rotating each display panel, 4, 5, or 6.

En ce qui concerne chaque panneau d'affichage, par exemple le panneau 4, il tourne autour d'un axe individuel de rotation parallèle à l'axe 3 du pied 1, et matérialisé par l'axe du support tubulaire 7, décrit ci-après en ce qui concerne le mécanisme de sécurité par friction représenté à la figure 4. L'axe individuel de rotation du panneau 4 est décalé par rapport au point médian A selon la largeur du même panneau, de manière à ménager dans ce dernier une section relativement étroite 4a et une section relativement large 4b, disposées de part et d'autre de l'axe de rotation individuel dudit panneau. Comme le montre la figure 2, l'intervalle séparant l'axe 3 du pied 1 et chaque axe individuel de rotation d'un panneau d'affichage, par exemple celui du panneau 4, est ajusté pour permettre uniquement le passage en rotation de la section étroite, par exemple, 4a, du même panneau, soit dans le sens de rotation 11, c'est-à-dire à partir de la position recto vers la position verso, soit dans le sens de rotation 12, c'est-à-dire à partir de la position verso vers la position recto, ces deux sens ayant été représentés respectivement aux figures 2 et 3. Les moyens de synchronisation 13 décrits ci-après sont associés aux différents moyens d'entraînement en rotation 10, affectés respectivement aux différents panneaux d'affichage 4, 5 et 6, pour entraîner en rotation ces derniers, en même temps, et successivement dans le sens de rotation 11 vers la position verso, et dans le sens de rotation 12 vers la position recto, selon les figures 1 et 2 respectivement.As regards each display panel, for example panel 4, it rotates around an individual axis of rotation parallel to the axis 3 of the stand 1, and materialized by the axis of the tubular support 7, described below. afterwards with regard to the friction safety mechanism shown in FIG. 4. The individual axis of rotation of the panel 4 is offset with respect to the midpoint A along the width of the same panel, so as to provide a section in the latter relatively narrow 4a and a relatively wide section 4b, arranged on either side of the individual axis of rotation of said panel. As shown in Figure 2, the interval between the axis 3 of the foot 1 and each individual axis of rotation of a display panel, for example that of the panel 4, is adjusted to allow only the passage in rotation of the narrow section, for example, 4a, of the same panel, either in the direction of rotation 11, that is to say from the front position towards the back position, or in the direction of rotation 12, that is that is to say from the back position towards the front position, these two directions having been represented respectively in FIGS. 2 and 3. The synchronization means 13 described below are associated with the different rotation drive means 10, assigned respectively to the various display panels 4, 5 and 6, in order to rotate the latter, at the same time, and successively in the direction of rotation 11 towards the back position, and in the direction of rotation 12 towards the front position, according to the Figures 1 and 2 respectively.

Grâce à ces moyens, caractérisant de manière générale la présente invention, la rotation de chaque panneau d'affichage intervient pour sa section relativement large par exemple 4b, à l'extérieur du volume fictif délimité par la rotation du support tournant 2, et pour sa section relativement étroite, par exemple 4a, à l'intérieur de ce même volume fictif. Une telle rotation peut s'effectuer sans inconvénient, puisque le support tournant est situé au sommet du pied ou mât 1, c'est-à-dire hors de portée de toute présence humaine. Grâce à cette disposition, et comme montré par les figures 2 et 3, l'encombrement hors-tout du dispositif d'affichage demeure relativement limité, puisque déterminé pour l'essentiel par la distance séparant l'axe 3 du mât et l'axe individuel de rotation de chaque panneau d'affichage.Thanks to these means, generally characterizing the present invention, the rotation of each display panel takes place for its relatively wide section, for example 4b, outside the fictitious volume delimited by the rotation of the rotating support 2, and for its relatively narrow section, for example 4a, inside this same fictitious volume. Such a rotation can be carried out without disadvantage, since the rotating support is located at the top of the foot or mast 1, that is to say out of reach of any human presence. Thanks to this arrangement, and as shown in FIGS. 2 and 3, the overall size of the display device remains relatively limited, since it is essentially determined by the distance separating the axis 3 of the mast and the axis individual rotation of each display panel.

Conformément aux figures 2 et 3, on observera que les 3 axes individuels de rotation 7, 8 et 9 des 3 panneaux d'affichage 4, 5 et 6 sont disposés selon le sommet d'un triangle équilatéral ayant pour centre l'axe 3 du mât ou pied 1. Pour ce faire, chaque flasque 14 ou 15 comprend 3 bras radiaux 18, 19 et 20, disposés à 120° les uns des autres, montés ou fixés sur un moyeu 16 ou 17, lequel est monté en rotation sur la partie supérieure 1b du pied 1. Les flasques 14 et 15 sont en coïncidence l'un par rapport à l'autre, de telle manière que leurs bras radiaux respectifs soient en vis -à -vis ; en conséquence, chaque axe individuel de rotation d'un panneau d'affichage 4, 5 ou 6 est disposé entre les deux extrémités de deux bras radiaux en vis à vis, de telle manière que chaque axe individuel de rotation d'un panneau donné est lié aux deux moyeux 16 et 17, par trois bras 18, 19, ou 20.In accordance with FIGS. 2 and 3, it will be observed that the 3 individual axes of rotation 7, 8 and 9 of the 3 display panels 4, 5 and 6 are arranged according to the apex of an equilateral triangle having the axis 3 of the center mast or foot 1. To do this, each flange 14 or 15 comprises 3 radial arms 18, 19 and 20, arranged at 120 ° from each other, mounted or fixed on a hub 16 or 17, which is rotatably mounted on the upper part 1b of the foot 1. The flanges 14 and 15 are in coincidence with each other, so that their respective radial arms are opposite; consequently, each individual axis of rotation of a display panel 4, 5 or 6 is arranged between the two ends of two radial arms facing each other, such that each individual axis of rotation of a given panel is linked to the two hubs 16 and 17, by three arms 18, 19, or 20.

Conformément à la figure 4, les moyens d'entraînement en rotation des différents panneaux d'affichage 4, 5 et 6, comprennent autant de moyens individuels 10 que de panneaux. Chaque moyen individuel 10 est fixé à l'extrémité libre d'un bras radial, 19 par exemple, et consiste dans l'accouplement d'un moteur 61, d'un moto-réducteur 62, et d'un axe vertical de sortie 63, disposé parallèlement à l'axe 3 du pied 1, ou selon l'axe de rotation du panneau d'affichage, par exemple 4. L'axe 63 entraîne un panneau d'affichage, par exemple 4, par l'intermédiaire d'un mécanisme 22 de sécurité par friction, permettant de désaccoupler le moteur 61 par rapport au même panneau, et ceci sous le contrôle du moyen de synchronisation 13 décrit ci-après. Plus précisément, le mécanisme de sécurité 22 comporte un disque menant 23, calé en rotation sur l'axe 63, disposés à plat sur l'âme du bras radial, par exemple 19, par l'intermédiaire de butées à aiguilles 64, ainsi qu'un disque mené 24, reposant à plat sur le disque menant 23 par l'intermédiaire d'un jonc de laiton de friction 65. C'est ce disque mené 24 qui présente une partie tubulaire 24a, déterminant l'axe de rotation du panneau d'affichage, ainsi qu'une bride 24b, parallèle à la partie 24c reposant sur le disque menant 23, et sur laquelle est monté de manière règlable en rotation le panneau d'affichage. Le moyen de synchronisation de la rotation des différents disques menés 24 est obtenu, au niveau de chaque moyen individuel 10 d'entraînement en rotation, par un pignon 66, calé en rotation sur la partie tubulaire 24a, et engrênant avec une chaîne sans fin 21, également représentée aux figures 2 et 3, dont le parcours à l'intérieur du flasque inférieur 14 est déterminé par différents tendeurs ou autres pignons de renvoi. Le profil de la chaine sans fin 21 est similaire au contour extérieur des trois bras 18, 19 et 20 formant le flasque inférieur 14.In accordance with FIG. 4, the means for driving in rotation the various display panels 4, 5 and 6 comprise as many individual means 10 as there are panels. Each individual means 10 is fixed to the free end of a radial arm, 19 for example, and consists of the coupling of a motor 61, a gear motor 62, and a vertical outlet axis 63 , arranged parallel to the axis 3 of the foot 1, or along the axis of rotation of the display panel, for example 4. The axis 63 drives a display panel, for example 4, by means of a friction safety mechanism 22, allowing the motor 61 to be uncoupled with respect to the same panel, and this under the control of the synchronization means 13 described below. More specifically, the safety mechanism 22 comprises a driving disc 23, fixed in rotation on the axis 63, arranged flat on the core of the radial arm, for example 19, by means of needle stops 64, as well as '' a driven disc 24, lying flat on the driving disc 23 by means of a friction brass rod 65. It is this driven disc 24 which has a tubular part 24a, determining the axis of rotation of the panel display, as well as a flange 24b, parallel to the part 24c resting on the driving disc 23, and on which is mounted in a manner adjustable in rotation the display panel. The means for synchronizing the rotation of the different driven discs 24 is obtained, at each individual means 10 for driving in rotation, by a pinion 66, fixed in rotation on the tubular part 24a, and meshing with an endless chain 21 , also shown in Figures 2 and 3, the path inside the lower flange 14 is determined by different tensioners or other idler gears. The profile of the endless chain 21 is similar to the external contour of the three arms 18, 19 and 20 forming the lower flange 14.

Grâce aux dispositions ainsi adoptées, il est possible d'entraîner en rotation les différents panneaux d'affichage, et ceci dans le même sens et de manière synchronisée. Tout blocage en rotation de l'un quelconque des panneaux, entraîne le débrayage de chaque moteur 61 par rapport au panneau individuel correspondant.Thanks to the arrangements thus adopted, it is possible to rotate the various display panels, and this in the same direction and in a synchronized manner. Any blocking in rotation of any one of the panels causes the disengagement of each motor 61 relative to the corresponding individual panel.

Bien entendu, les moyens précédemment décrits, assurant l'entraînement en rotation et la synchronisation des différents panneaux 4, 5 et 6 peut être obtenu de manière différente, par exemple par la chaîne sans fin 21, entraînée en rotation par un seul organe, à savoir un moto-réducteur, ou un vérin hydraulique double effet agissant sur la chaîne. L'utilisation d'un vérin hydraulique permet au surplus différentes vitesses de rotation des panneaux, dont une lente pour la fin de course d'inversion recto-verso des mêmes panneaux.Of course, the means described above, ensuring the rotational drive and the synchronization of the different panels 4, 5 and 6 can be obtained in a different way, for example by the endless chain 21, driven in rotation by a single member, at know a gear motor, or a double acting hydraulic cylinder acting on the chain. The use of a hydraulic cylinder also allows different speeds of rotation of the panels, including a slow one for the end of the two-sided reversal travel of the same panels.

Dans leurs positions recto et verso, les panneaux 4, 5 et 6 peuvent être accouplés les uns et autres de manière positive, pour obtenir dans chaque position une bonne rigidité de l'ensemble du support tournant 2. A cette fin, et comme montré de manière schématique par les figures 2 et 3, chaque panneau, à sa partie inférieure comporte d'un côté un organe mâle 25 d'accouplement avec deux têtes 25a et 25b opposées de jonction, et de l'autre côté un organe femelle 26 de jonction. Compte tenu de cette disposition, dans la position recto de la figure 2, c'est la tête 25b qui vient en correspondance avec l'organe 26 femelle d'un panneau adjacent, et dans la position verso selon figure 3 c'est la tête 25a qui vient en correspondance avec un organe femelle 26 de jonction.In their front and back positions, the panels 4, 5 and 6 can be positively coupled to each other, in order to obtain in each position good rigidity of the assembly of the rotating support 2. To this end, and as shown from schematically by Figures 2 and 3, each panel, at its lower part comprises on one side a male member 25 for coupling with two opposite junction heads 25a and 25b, and on the other side a female member 26 for junction . In view of this arrangement, in the front position of FIG. 2, it is the head 25b which comes in correspondence with the female member 26 of an adjacent panel, and in the back position according to FIG. 3 it is the head 25a which comes in correspondence with a female junction member 26.

Comme représenté à la figure 5, dans chaque position en correspondance d'une tête d'accouplement avec un organe femelle de jonction, un mécanisme 27 permet de verrouiller ces deux éléments l'un sur l'autre, selon tout mode d'exécution approprié. Ainsi, selon cette même figure 5, chaque tête 25a consiste en une tige plate pourvue à son extrémité libre d'une lumière 25c, et chaque organe femelle 26 consiste en deux ailes 68 et 69, solidaires de la partie inférieure d'un panneau 4, comportant deux lumières 68a et 69a respectivement en coïncidence, et dans l'interstice desquelles vient s'insérer la tige plate 25a ; dans la position d'insertion, les lumières 68a, 25c et 69a sont en coïncidence. Le mécanisme 27 de verrouillage comporte un levier 70, monté rotatif à une extrémité sur une partie fixe 71, et comportant à son autre extrémité libre un téton 72, pénétrant dans la position verrouillée dans l'alignement des lumières 68a, 25c et 29a. Ce téton est commandé en position désengagée, par activation de l'électro-aimant 73 agissant sur le levier 70, à l'encontre du moyen de rappel 74, ou ressort. Dans la position désactivée de l'électro-aimant 73, le moyen de rappel 74 déplace le téton 72 dans l'alignement des lumières 68a, 25c et 69a, pour aboutir au verrouillage recherché.As shown in FIG. 5, in each position in correspondence of a coupling head with a female junction member, a mechanism 27 makes it possible to lock these two elements one on the other, according to any suitable embodiment. Thus, according to this same FIG. 5, each head 25a consists of a flat rod provided at its free end with a lumen 25c, and each female member 26 consists of two wings 68 and 69, integral with the lower part of a panel 4 , comprising two slots 68a and 69a respectively in coincidence, and in the interstice of which is inserted the flat rod 25a; in the insertion position, the lights 68a, 25c and 69a are in coincidence. The locking mechanism 27 comprises a lever 70, rotatably mounted at one end on a fixed part 71, and comprising at its other free end a stud 72, penetrating into the locked position in alignment with the slots 68a, 25c and 29a. This pin is controlled in the disengaged position, by activation of the electromagnet 73 acting on the lever 70, against the return means 74, or spring. In the deactivated position of the electromagnet 73, the return means 74 moves the stud 72 in alignment with the slots 68a, 25c and 69a, to achieve the desired locking.

Conformément aux figures 6 et 7, le flasque supérieur 15 est tourillonné sur la partie supérieure 1b du mat 1, par montage en rotation du moyeu 17 sur la partie 1b par l'intermédiaire de roulements 75 de guidage axial, et d'un roulement 76 disposé sur un épaulement de la partie 1b, et supportant le poids du support tournant 2. La rotation de ce dernier est assurée par un moteur non représenté, monté sur le dessus du flasque 15, entraînant en rotation un axe 77 tourillonné sur le flasque 15, et solidaire d'un pignon inférieur 78, lequel engraine avec une couronne dentée 79, fixée sur l'épaulement précité du pied 1b, et sur laquelle repose en définitive le flasque 15 par l'intermédiaire du roulement 76.In accordance with FIGS. 6 and 7, the upper flange 15 is journalled on the upper part 1b of the mast 1, by mounting the hub 17 in rotation on the part 1b by means of bearings 75 for axial guidance, and a bearing 76 disposed on a shoulder of part 1b, and supporting the weight of the rotating support 2. The rotation of the latter is ensured by a motor, not shown, mounted on top of the flange 15, driving in rotation an axis 77 journalled on the flange 15 , and secured to a lower pinion 78, which engages with a toothed crown 79, fixed on the aforementioned shoulder of the foot 1b, and on which ultimately rests the flange 15 by means of the bearing 76.

Conformément à la figure 7, le dispositif d'affichage comprend un moyen de blocage en rotation du support tournant 2 par rapport au pied 1, ce moyen s'avérant en particulier utile comme décrit ci-après pour bloquer la rotation dudit support, lorsque la vitesse du vent atteint un certain seuil. Ce moyen de blocage comprend :

  • une couronne 51 de blocage, fixée à plat sur l'épaulement séparant la partie inférieure 1a et la partie supérieure 1b du pied 1, cette couronne comportant des trous 51a régulièrement répartis sur son périmètre,
  • une platine 80 comportant un orifice 80a, monté sur la partie inférieure du moyeu 17,
  • un tube de guidage 81, emmanché verticalement, c'est-à-dire parallèlement à l'axe 3 du pied 1, dans l'orifice 80a de la platine 80,
  • un dispositif de commande 82, monté à l'extrémité haute du tube de guidage 81, consistant en un électro-aimant, commandant une clavette 52, en vis -à -vis de la couronne 51 ; cette clavette est commandée par l'électro-aimant 82, parallèlement à l'axe 3 du pied 1, entre deux positions, à savoir une position haute dans laquelle la clavette est désengagée de la couronne de blocage 51, et une position basse dans laquelle, par simple gravité et guidée par le tube 80, la clavette s'est engagée dans un trou 51a de la couronne 51.
In accordance with FIG. 7, the display device comprises a means for blocking the rotation of the rotating support 2 relative to the foot 1, this means proving in particular useful as described below for blocking the rotation of said support, when the wind speed reaches a certain threshold. This blocking means includes:
  • a locking crown 51, fixed flat on the shoulder separating the lower part 1a and the upper part 1b from the foot 1, this crown comprising holes 51a regularly distributed around its perimeter,
  • a plate 80 comprising an orifice 80a, mounted on the lower part of the hub 17,
  • a guide tube 81, fitted vertically, that is to say parallel to the axis 3 of the foot 1, in the orifice 80a of the plate 80,
  • a control device 82, mounted at the upper end of the guide tube 81, consisting of an electromagnet, controlling a key 52, opposite the crown 51; this key is controlled by the electromagnet 82, parallel to the axis 3 of the foot 1, between two positions, namely a high position in which the key is disengaged from the locking crown 51, and a low position in which , by simple gravity and guided by the tube 80, the key is engaged in a hole 51a of the crown 51.

Pour terminer, le dispositif d'affichage est équipé de différents organes de contrôle ou commande, permettant notamment de :

  • bloquer la rotation recto-verso des panneaux d'affichage, au-delà d'un premier seuil S 2 de vitesse du vent, ce dernier étant détecté par un anémomètre,
  • bloquer la rotation du support tournant 2, au-delà d'un second seuil S 1 de vitesse du vent supérieur au premier seuil S 2, toujours mesuré par le même anémomètre.
Finally, the display device is equipped with various monitoring or control devices, making it possible in particular to:
  • block the two-sided rotation of the display panels, beyond a first threshold S 2 of wind speed, the latter being detected by an anemometer,
  • block the rotation of the rotating support 2, beyond a second threshold S 1 of wind speed greater than the first threshold S 2, always measured by the same anemometer.

A cette fin, un micro-processeur chargé d'un programme de commande ou contrôle permet de dérouler les différentes fonctions montrées par l'organigramme sur la page ci-après.

To this end, a microprocessor responsible for a command or control program makes it possible to carry out the various functions shown by the flowchart on the page below.

Les modifications suivantes peuvent être substituées en tout ou partie au mode d'exécution précédemment décrit.The following modifications may be substituted in whole or in part for the mode of execution previously described.

La rotation du support tournant 2 et le blocage en rotation de ce dernier par rapport au pied 1 peuvent être obtenus, non avec des moyens séparés comme décrit respectivement par rapport aux figures 6 et 7, mais avec un moyen unique. Ce dernier consiste en un entraînement direct par chaîne, avec une roue montée coaxialement sur le support tournant, et un pignon monté sur le mât ou socle du dispositif ; le pignon est entraîné en rotation par un moto-réducteur avec un frein électro-magnétique à manque de courant, qui assure à la fois l'entraînement et le blocage en rotation du pignon, et donc du support tournant.The rotation of the rotating support 2 and the locking in rotation of the latter relative to the foot 1 can be obtained, not with separate means as described respectively with respect to Figures 6 and 7, but with a single means. The latter consists of a direct chain drive, with a wheel mounted coaxially on the rotating support, and a pinion mounted on the mast or base of the device; the pinion is driven in rotation by a gear motor with an electromagnetic brake with lack of current, which ensures both the drive and the locking in rotation of the pinion, and therefore of the rotating support.

Pour des panneaux de surface ou dimensions relativement limitées, le dispositif d'entraînement en rotation individuelle de chaque panneau peut être remplacé par un entraînement direct, sans mécanisme 2 de sécurité par friction, consistant à déplacer la chaîne 21 sans fin par un seul moyen moteur, unique et commun pour les trois panneaux ; conférer figure 4.For panels of relatively limited surface or dimensions, the device for driving in individual rotation of each panel can be replaced by a direct drive, without a safety mechanism 2 by friction, consisting in moving the endless chain 21 by a single motor means , unique and common for the three panels; confer figure 4.

Pour un dispositif d'affichage disposé à l'intérieur d'un bâtiment, ou dans une zone peu exposée au vent, le dispositif d'accouplement des panneaux entre eux, décrit par référence à la figure 5 peut être supprimé.For a display device placed inside a building, or in an area little exposed to the wind, the device for coupling the panels together, described with reference to FIG. 5, can be omitted.

L'ensemble constitué par le support tournant et les panneaux rotatifs a été décrit et explicité à la partie supérieure d'un mât ou pied. Il est bien entendu que le même ensemble peut être suspendu à la partie inférieure d'un mât, lui-même fixé en partie haute, par exemple sur un plafond, les éléments fonctionnels précédemment décrits demeurant inchangés.The assembly constituted by the rotating support and the rotating panels has been described and explained at the top of a mast or foot. It is understood that the same assembly can be suspended from the lower part of a mast, itself fixed in the upper part, for example on a ceiling, the functional elements previously described remaining unchanged.
