Description

La présente invention est relative aux panneaux d'affichage et aux dispositifs comprenant de tels panneaux.The present invention relates to billboards and devices comprising such panels.

Plus particulièrement, l'invention concerne un panneau d'affichage comprenant une structure rigide qui présente au moins une face d'affichage adaptée pour présenter au moins un affichage (sur support papier ou feuille synthétique, ou éventuellement électronique).More particularly, the invention relates to a display panel comprising a rigid structure which has at least one display face adapted to present at least one display (on paper or synthetic sheet, or possibly electronic).

Les panneaux d'affichages de ce type sont souvent des panneaux de grande taille, destinés à être installés en hauteur notamment dans des lieux publics, pour être bien vus de loin. Lorsqu'un opérateur doit accéder au panneau pour remplacer une affiche (lorsqu'il s'agit d'un panneau pour affiches en papier ou synthétiques) ou plus généralement pour effectuer une opération de maintenance, cet accès peut s'avérer difficile en pratique et nécessite le plus souvent l'installation d'une passerelle au sol. L'installation de cette passerelle au sol est relativement longue et complexe (l'opérateur doit installer des pieds au sol, puis poser la passerelle dessus) et implique en outre souvent que le sol ait été aménagé à cet effet pour assurer une assise stable des pieds sur le sol. Enfin, même en ayant aménagé le sol, cette configuration présente un risque pour la sécurité de l'opérateur, puisque les pieds posés au sol peuvent être déstabilisés par un piéton ou un véhicule. Le document FR 2483108 A est considéré comme l'état de la technique le plus proche.Display panels of this type are often large panels, intended to be installed high in particular in public places, to be seen from afar. When an operator needs to access the panel to replace a poster (when it is a panel for paper or synthetic posters) or more generally to carry out a maintenance operation, this access can be difficult in practice and most often requires the installation of a footbridge. The installation of this footbridge on the ground is relatively long and complex (the operator must install feet on the ground, then put the footbridge on it) and also often implies that the ground was arranged for this purpose to ensure a stable sitting of feet on the floor. Finally, even having laid the ground, this configuration presents a risk to the safety of the operator, since the feet on the ground can be destabilized by a pedestrian or a vehicle. The document FR 2483108 A is considered the closest state of the art.

La présente invention a notamment pour but de pallier ces inconvénients.The present invention is intended to overcome these disadvantages.

A cet effet, selon l'invention, un panneau d'affichage du genre en question est caractérisé en ce qu'il comporte en outre au moins deux jambages de support montés mobiles sur la structure, entre :

  • une position d'utilisation où lesdits jambages sont adaptés pour recevoir une passerelle sensiblement horizontale permettant à un opérateur d'accéder à la structure,
  • et une position escamotée où lesdits jambages de support sont escamotés dans ladite structure.
For this purpose, according to the invention, a display panel of the kind in question is characterized in that it further comprises at least two support legs mounted movably on the structure, between:
  • a use position where said legs are adapted to receive a substantially horizontal bridge allowing an operator to access the structure,
  • and a retracted position where said support legs are retracted into said structure.

Grâce à ces dispositions, l'installation de la passerelle est grandement facilitée pour l'opérateur, puisqu'il n'a plus besoin d'installer des pieds au sol afin de supporter la passerelle. On améliore également ainsi la sécurité de l'opérateur, puisque les jambages de support de la passerelle sont tenus par la structure panneau et non plus posés au sol. De plus, en dehors des périodes d'utilisation, les jambages de support sont escamotés dans la structure du panneau, donc le panneau ne présente pas un encombrement supérieur à la normale.With these provisions, the installation of the bridge is greatly facilitated for the operator, since it no longer needs to install feet on the ground to support the bridge. It also improves the safety of the operator, since the support legs of the bridge are held by the panel structure and no longer placed on the ground. In addition, outside periods of use, the support legs are retracted in the panel structure, so the panel does not present a larger than normal size.

Dans divers modes de réalisation du panneau d'affichage selon l'invention, on peut éventuellement avoir recours en outre à l'une et/ou à l'autre des dispositions suivante :

  • les jambages de support sont suspendus à la structure du panneau ;
  • la structure du panneau comporte un cadre qui présente une traverse inférieure, une traverse supérieure et deux montants latéraux, les jambages de support étant montés mobiles verticalement dans la cadre et étant adaptés pour sortir du cadre en position d'utilisation au travers d'au moins un passage ménagé dans la traverse inférieure ;
  • les jambages de support comportent chacun :
    • un poteau sensiblement vertical qui est monté coulissant sensiblement verticalement dans le cadre,
    • et un bras monté mobile sur le poteau entre une position déployée où ledit bras est sensiblement horizontal et adapté pour porter la passerelle, les bras des deux jambages de support s'étendant alors dans une même direction, et une position repliée où ledit bras s'étend parallèlement au poteau et est adapté pour traverser ledit au moins un passage de la traverse inférieure du cadre ;
  • le bras est monté pivotant sur le poteau et est renforcé par une bielle coulissante qui est montée pour être dans une position de butée lorsque le bras est en position déployée, ladite bielle s'étendant alors en biais entre une extrémité reliée au bras et une extrémité reliée au poteau ;
  • la bielle présente une extrémité montée pivotante sur le bras et une extrémité montée coulissante sur le poteau ;
  • le poteau présente une ouverture latérale dans laquelle sont montés le bras et la bielle, le bras et la bielle étant adaptés pour se loger dans cette ouverture latérale dans la position repliée du bras ;
  • le poteau est monté coulissant dans un guide vertical tubulaire solidaire du cadre ;
  • le poteau est suspendu à un lien souple adapté pour déplacer verticalement ledit poteau ;
  • ledit lien souple est relié à un treuil ;
  • les liens souples des deux poteaux sont commandés par un treuil unique ;
  • le cadre est porté par un piètement et ledit treuil unique est situé dans le piètement et est adapté pour être commandé par une manivelle amovible montée rotative sur ledit piètement.
In various embodiments of the display panel according to the invention, one can optionally also resort to one and / or the other of the following provisions:
  • support jambs are suspended from the panel structure;
  • the panel structure comprises a frame having a bottom rail, a top rail and two side posts, the support legs being movably mounted vertically in the frame and being adapted to exit the frame in the use position through at least one a passage in the lower rail;
  • support jambs each include:
    • a substantially vertical pole which is slidably mounted substantially vertically in the frame,
    • and a movably mounted arm on the post between an extended position where said arm is substantially horizontal and adapted to carry the bridge, the arms of the two support legs then extending in the same direction, and a folded position where said arm s' extends parallel to the post and is adapted to traverse said at least one passage of the lower cross member of the frame;
  • the arm is pivotally mounted on the post and is reinforced by a sliding rod which is mounted to be in an abutment position when the arm is in the extended position, said connecting rod then extending at an angle between an end connected to the arm and an end connected to the pole;
  • the connecting rod has an end pivotally mounted on the arm and an end slidably mounted on the pole;
  • the post has a lateral opening in which are mounted the arm and the connecting rod, the arm and the connecting rod being adapted to be housed in this lateral opening in the folded position of the arm;
  • the post is slidably mounted in a tubular vertical guide secured to the frame;
  • the post is suspended from a flexible link adapted to vertically move said post;
  • said flexible link is connected to a winch;
  • the flexible links of the two poles are controlled by a single winch;
  • the frame is carried by a base and said single winch is located in the base and is adapted to be controlled by a removable crank rotatably mounted on said base.

Par ailleurs, l'invention a également pour objet un dispositif comprenant un panneau d'affichage tel que défini ci-dessus et une passerelle amovible adaptée pour être portée par les jambages de support lorsqu'ils sont en position d'utilisation.Furthermore, the invention also relates to a device comprising a display panel as defined above and a removable bridge adapted to be carried by the support legs when in the position of use.

Sur les différentes figures, les mêmes références désignent des éléments identiques ou similaires.In the different figures, the same references designate identical or similar elements.

Les figures 1 et 2 représentent un panneau d'affichage 1, destiné notamment à être disposé dans un lieu public, par exemple la voie publique, un aéroport, une gare, un centre commercial, etc.The figures 1 and 2 represent a billboard 1, intended in particular to be placed in a public place, for example the public road, an airport, a station, a shopping center, etc.

Le panneau d'affichage 1 comporte une structure rigide 2, métallique ou autre, qui est portée par un piètement 3 pouvant le cas échéant être lui-même métallique et reposant sur le sol 4. La structure rigide 2 comporte une ou deux faces d'affichage 5 généralement vitrées, qui sont adaptées pour présenter au moins un affichage (affichage papier, affichage sur support synthétique ou affichage électronique), cette face d'affichage étant portée par un cadre 6 qui peut par exemple présenter une traverse intérieure 7 sensiblement horizontale, deux montants latéraux 8 sensiblement verticaux et une traverse supérieure 9 sensiblement horizontale.The display panel 1 comprises a rigid structure 2, metallic or otherwise, which is carried by a base 3 which may be itself metallic and resting on the ground 4. The rigid structure 2 comprises one or two faces of display 5 generally glazed, which are adapted to present at least one display (paper display, display on synthetic medium or electronic display), this display face being carried by a frame 6 which may for example have a substantially horizontal inner cross member 7, two substantially vertical lateral uprights 8 and a crossbar upper 9 substantially horizontal.

Comme on peut le voir sur les figures 2 et 3, le panneau d'affichage 1 comporte en outre deux jambages de support 10 qui sont normalement en position escamotée à l'intérieur de la structure 2. Ces jambages de support 10, qui peuvent par exemple être réalisés à l'aide de profilés métalliques, peuvent être montés coulissants dans des guides tubulaires sensiblement verticaux 20 disposés à l'intérieur de la structure 2 du panneau et être adaptés pour sortir de cette structure 2 par au moins un passage 17 ménagé dans la traverse inférieure 7 du cadre de la structure (dans l'exemple considéré ici, la traverse inférieure 7 comporte deux passages 17, un pour chaque jambage de support 10). Les jambages de support 10 sont suspendus à des câbles métalliques 21 ou autres liens souples, lesquels câbles métalliques s'étendent vers le haut à partir de l'extrémité supérieure de chaque jambage de support 10 avant d'être renvoyés horizontalement puis verticalement vers le bas chacun par deux poulies 22, les câbles 21 respectifs des deux jambages de support étant reliés ensuite à un câble unique 23 qui est enroulé sur un treuil 24 disposé dans le piètement 3 du panneau. Ce treuil peut être commandé manuellement au moyen d'une manivelle 25 de préférence amovible, pouvant être montée rotative sur le piétement 3. En variante, le treuil 24 pourrait être un treuil électrique.As can be seen on the figures 2 and 3 , the display panel 1 further comprises two support legs 10 which are normally in the retracted position inside the structure 2. These support legs 10, which may for example be made using metal profiles, can be slidably mounted in substantially vertical tubular guides 20 disposed within the structure 2 of the panel and be adapted to exit this structure 2 by at least one passage 17 formed in the lower crossbar 7 of the frame of the structure (in the example considered here, the lower crossbar 7 has two passages 17, one for each support leg 10). The support legs 10 are suspended from metal cables 21 or other flexible links, which wire ropes extend upward from the upper end of each support leg 10 before being returned horizontally and then vertically downwards. each by two pulleys 22, the respective cables 21 of the two support legs being subsequently connected to a single cable 23 which is wound on a winch 24 disposed in the base 3 of the panel. This winch can be controlled manually by means of a crank 25 preferably removable, can be rotatably mounted on the base 3. Alternatively, the winch 24 could be an electric winch.

Comme représenté sur les figures 4 et 5, lorsqu'un opérateur 12 veut accéder à la structure 2 du panneau, par exemple pour changer l'affichage ou pour toute autre opération de maintenance, il actionne la manivelle 3 pour faire descendre les jambages de support 10 sous le panneau, puis déploie des bras 15 situés à l'extrémité inférieure des jambages de support 10 de façon à pouvoir positionner sur ces bras 15 une passerelle 11 horizontale au moyen de laquelle il peut accéder à l'ensemble de la structure 2 du panneau, notamment après avoir partiellement ouvert les faces d'affichage 5 du panneau ou une de ces faces.As shown on figures 4 and 5 when an operator 12 wants to access the structure 2 of the panel, for example to change the display or for any other maintenance operation, he actuates the crank 3 to lower the support legs 10 under the panel, then deploys arm 15 located at the lower end of the support legs 10 so as to position on these arms 15 a horizontal bridge 11 by means of which it can access the entire structure 2 of the panel, in particular after partially open the display faces 5 of the panel or one of these faces.

Les jambages de support 10 étant entièrement portés par la structure 2 du panneau, à laquelle ils sont suspendus, l'opérateur n'a plus besoin d'installer des pieds au sol pour porter sa passerelle, de sorte que l'installation de la passerelle 11 est simplifiée. De plus, la sécurité de l'opérateur 12 est également améliorée, puisque l'on diminue ainsi les risques de voir la passerelle 11 déstabilisée par un choc avec un piéton ou un véhicule.The support legs 10 being entirely worn by the structure 2 of the panel, to which they are suspended, the operator no longer needs to install feet on the ground to carry his gateway, so that the installation of the gateway 11 is simplified. In addition, the safety of the operator 12 is also improved, since it reduces the risk of seeing the bridge 11 destabilized by a shock with a pedestrian or a vehicle.

Comme représenté plus en détail sur les figures 6 à 9, chaque jambage de support 10 peut comporter par exemple un poteau 13 sensiblement vertical qui présente, sur son côté avant parallèle à l'une des phases d'affichage 5 du panneau, une ouverture 14 dans laquelle est monté pivotant le bras 15, autour d'un pivot 15a. L'extrémité libre du bras 15 peut être en outre montée pivotante sur une bielle 16, à l'aide d'un pivot 16a, l'extrémité opposée de la bielle 16 étant quant à elle montée coulissante dans l'ouverture 14 du poteau, par exemple par des pivots 16b de la bielle qui coulissent dans des fentes verticales 16c du poteau. La position déployée sensiblement horizontale du bras 15 correspond à une position de butée de la bielle 16, où les pivots 16b de la bielle butent contre une extrémité inférieure des glissières 16c du poteau, de sorte que la bielle 16b assure que la position déployée horizontale du bras 15 est une position parfaitement stable, dans laquelle la passerelle 11 peut être supportée de façon fiable sur les bras 15.As shown in more detail on Figures 6 to 9 each support leg 10 may comprise, for example, a substantially vertical pole 13 which has, on its front side parallel to one of the display phases 5 of the panel, an opening 14 in which is pivotally mounted the arm 15, around a pivot 15a. The free end of the arm 15 may also be pivotally mounted on a connecting rod 16, by means of a pivot 16a, the opposite end of the connecting rod 16 being slidably mounted in the opening 14 of the post, for example by pivots 16b of the rod which slide in vertical slots 16c of the pole. The substantially horizontal deployed position of the arm 15 corresponds to an abutment position of the connecting rod 16, where the pivots 16b of the connecting rod abut against a lower end of the rails 16c of the post, so that the connecting rod 16b ensures that the horizontal deployed position of the arm 15 is a perfectly stable position, in which the bridge 11 can be reliably supported on the arms 15.

De plus, comme représenté sur les figures 7B, 8 et 9, le bras 15 peut être replié à l'intérieur de l'ouverture 14 du poteau, de même que la bielle 16. Pour assurer la stabilité de cette position repliée, notamment avant que le bras 15 et la bielle 16 ne soient engagés à l'intérieur du guide 20 correspondant, chaque jambage de support peut avantageusement comporter des moyens de rétention permettant de retenir le bras 15 et la bielle 16 en position repliée.Moreover, as shown on Figures 7B , 8 and 9 , the arm 15 can be folded inside the opening 14 of the post, as well as the rod 16. To ensure the stability of this folded position, especially before the arm 15 and the rod 16 are engaged to the Inner of the corresponding guide 20, each support leg may advantageously comprise retention means for retaining the arm 15 and the rod 16 in the folded position.

Dans l'exemple représenté, ces moyens de rétention peuvent comporter par exemple un tenon 18 solidaire de la bielle 16, adapté pour s'emboîter élastiquement dans un ressort 19 en forme de U qui est solidaire du poteau 13, ce ressort 19 retenant par friction le tenon 18 et donc la bielle 16 dans la position repliée.In the example shown, these retention means may comprise, for example, a tenon integral with the connecting rod 16, adapted to interlock elastically in a U-shaped spring 19 which is integral with the pole 13, the spring 19 holding frictionally the pin 18 and therefore the rod 16 in the folded position.

Selon une variante préférée, le ressort en U 19 pourrait être remplacé par un aimant (non représenté) adapté pour attirer et retenir la bielle 16 en position repliée.According to a preferred variant, the U-shaped spring 19 could be replaced by a magnet (not shown) adapted to attract and retain the connecting rod 16 in the folded position.
