Definitions

• the invention relates to a display device for scrolling images juxtaposed and forming a band.
• a display device can in particular serve as a support for several advertising campaigns when it is a billboard advertising.
• the invention is more particularly a modular structure particularly compact and easily removable into several independent elements, which has multiple advantages, especially for routing from the place of manufacture to the installation site.
• the display devices are formed by rigid boxes assembled at the factory and then transported to their place of use.
• this type of display device assembled in the form of a box is well adapted to small posters, and in particular posters whose surface is less than 2 m 2 . Indeed, in this case the boxes can be easily transported in a standard vehicle to their place of use.
• Such a display device is therefore not suitable for large posters and the transport and assembly of the various elements constituting it is not not easy to achieve. Indeed, it is necessary firstly to position the flat base and secondly to place the independent lower roller later.
• the object of the invention is to facilitate the handling and transport of display devices from their place of production to their place of use, which can be very remote and require transportation by air in particular.
• the invention proposes to limit to the minimum the number of independent elements while facilitating their subsequent assembly.
• the poster band is wound on drive rollers of which at least one is motorized.
• the rolls are necessarily longer than the width of the poster band which leads to very significant weight especially in the case of large format panels.
• the mechanical bearing structure and the bearings capable of making a pivot connection between the different rollers and the rest of the device must thus be dimensioned accordingly.
• Another object of the invention is to use drive rollers which are as short as possible to reduce on the one hand, the weight of the display device but also the entire mechanical structure for supporting them. Indeed, the use of rollers of small dimensions makes it possible on the one hand to facilitate their transport but also to simplify the mechanical structure of the display device.
• the invention therefore relates to a display device with horizontal or vertical scrolling, alternating or continuous.
• this type of display device can be used to scroll at least two juxtaposed posters forming a band that can be endless in which case the scroll is of continuous type and the images scroll in a single direction.
• the band may also be discontinuous.
• each end of the strip is secured to a roller, the scroll is then alternating in two opposite directions.
• Such a device comprises a substantially rectangular parallelepiped outer geometry and the posters are displayed at a rectangular front frame.
• the strip is itself driven in a translation movement parallel to the front frame by means of at least one motorized roller.
• substantially parallelepipedic one also understands prismatic forms whose base can be in particular that of a trapezium.
• the face at the front frame may be wider than the rear face of the device. Such an arrangement then makes it possible to achieve an optical effect aimed at making the device less shallow.
• the device is characterized in that it comprises two independent modules, each comprising means for guiding in rotation at least one motorized roller or at least one idler roller.
• the modules are assembled together by at least one beam , and arranged at the smaller dimension of the rectangle formed by the front frame.
• such a device is constituted by at least three elements joined together.
• the beam makes it possible to maintain the two modules at a predetermined distance according to the largest dimension of the posters to be scrolled.
• the motorized or idle rollers are arranged in pivot connection with respect to the structure of each module. Each roll is therefore constantly protected within the volume defined by a module.
• the device a modular structure easily transportable and assembled on site.
• the modules are small, which facilitates their handling, storage, and reduces the size of the roller associated with the motor module of the display device.
• the display device may comprise transverse tensioning means of the strip.
• a tension is obtained by stretching the band perpendicular to its direction of travel.
• This transverse tension makes it possible to give the poster visual qualities in terms of flatness, whatever the conditions of the external environment in which the poster is presented.
• the transverse tension allows in particular to improve the wind resistance of the poster.
• the transverse tensioning means of the strip may comprise slides in which penetrate rushes or equivalent, present on the lateral edges of the strip.
• the band can be equipped at its selvedges sections of profiles having a bead and able to penetrate at the end of a slide.
• a flat portion of the rod emerges from the slideway at a groove and is connected by one of the gluing, welding or similar means to the band formed by the posters.
• the ring is also at the edges of the band.
• a rod may be made of a low friction material so as to facilitate the sliding of the rod inside the slide.
• At least one of the slides can be movable in translation transversely to the direction of advancement of the strip. Indeed, the displacement of this slide relative to the other allows for an adjustment of the tension of the band, and in particular at the viewing face of the posters at the front frame.
• the transverse tensioning means of the strip may comprise resilient return members secured by its ends with, on the one hand, the movable slide, and, on the other hand, the beam that secures the two modules together.
• the tension of the band is obtained by stretching the elastic return members in a working position.
• the band is then inserted into the movable slideway to achieve the transverse tension of the band.
• the elastic return members then tend constantly to return to their rest position by bringing the movable slide of the beam on which they are fixed.
• the display device may comprise means for longitudinal tensioning of the strip.
• a voltage can be obtained in particular by controlling the power supply of the motorized rollers.
• it can also be obtained by changing the distance between two rollers and thus reducing or increasing the path traveled by the band.
• the longitudinal tensioning means of the strip may comprise a roller movable in translation relative to at least one motorized roller in pivot connection with one of the modules.
• roller movable in translation being non motorized.
• This "crazy" roll is thus both in pivot connection to allow guiding of the strip, but also in sliding connection in a direction perpendicular to its axis of rotation to generate the longitudinal tension.
• the roller movable in translation to achieve the longitudinal tension can be positioned inside or outside a module.
• the path of the strip makes it easier to assemble the two modules forming the display device and to place the strip on such a device.
• the roller movable in translation can be positioned outside the modules between two beams.
• the path of the band must be increased inside the parallelepiped shaped device.
• the band makes a detour and its path can make a round trip between the visible face of the band at the front frame and the rear face of the device.
• the means for moving in translation the movable roller can then be of different types, including using mechanical means such as counterweight pulleys so as to use the force of gravity to move the movable roller. But different means can be used and in particular elastic return means, or electrical devices for remotely controlling the translation movement of the mobile roller.
• the display device may comprise attachment means disposed on its rear face. In this way, the display device can be suspended from its rear face on an existing wall or panel.
• attachment means can be limited only to the area of the independent modules or extend on the beams connecting the two modules.
• the device may also include a lighting system of the moving strip.
• a lighting system of the moving strip can operate on the principle of backlighting, the band passing in front of the illuminating panel so as to allow viewing posters even in the dark.
• the band is backlit so that it is constantly visible or attracted to the passerby thanks to very bright colors.
• each module can comprise several motorized rollers.
• the motorization of the rollers can be carried out independently by means of several motors, but it can also use a single motor driving a chain or a belt in connection with the various motorized rollers.
• the motorization may be located in a housing that is independent of the module or at the end of the rollers.
• electronic control means can make it possible to synchronize the supply of the different rollers so as to generate the longitudinal tension of the band but also so as to perform an alternating movement of the band.
