Definitions

  • the invention relates to the display industry and more specifically to the animated display sector operating by the unwinding of a canvas comprising several juxtaposed panels. It relates more particularly to a structure of a display device by unwinding, which allows the use of posters of very large format, which can in particular be used outdoors.
  • such a strip is initially wound on a first roller, and its free end is wound on a second roller, motorized in synchronism with the first.
  • the posters used in this type of device consist of printed panels connected to constitute the poster itself.
  • the use of posters printed on paper constitutes an obstacle to the realization of such devices in very large format. Indeed, when the number of connections to be made between the printed panels exceeds a certain limit, the operations to constitute the poster itself become long, tedious and can even cause distortions in the quality of the image.
  • the folds constitute the extra thicknesses at the level of the winding of the strip, which can cause deformation or blockage of the winding system.
  • a second technique is known using dynamic display, which is mainly used in advertising media installed around the playing areas of sports facilities.
  • Such devices are distributed at the edge of the grounds so as to be in the field of television broadcasting cameras, and the mechanism for unfolding the poster is actuated as and when retransmission, depending on the location of the advertising space.
  • such devices Because of their exposure to the risk of shock, such devices must be able to withstand significant efforts, and are therefore relatively modest in size. More generally, such devices are equipped with a solid panel installed at the rear of the information carrier, and intended to ensure its rigidity to withstand impacts. The design of such devices is opposed to their declination in large sizes, since the information carrier is not stretched and is therefore subject to external constraints such as wind, which prevents proper winding.
  • the objective of the invention is to provide a scrolling display device which can be declined in a multiplicity of formats, in particular in large dimensions, while being capable of withstanding atmospheric phenomena capable of deforming the poster and of cause the formation of folds, particularly detrimental to the quality of the winding.
  • the invention therefore relates to a display device for unwinding an information support canvas, in which the canvas is wound and unwound around two synchronized motorized rollers, so that the canvas is kept under tension during its progress.
  • the fixing module is connected to the upper roller by a drop-down mechanism allowing the fixing module to be moved near the lower roller, for mounting and dismounting the upper end of the fabric;
  • the positioning of the poster around the drive rollers is done at a specific element, mechanically separable from the upper roller, to facilitate the operations of set up by bringing this fixing module closer to the lower area of the roll-down panel, that is to say near the lower roller.
  • the actuation of the upper roller therefore ensures the ascent of the fixing module and the joining of the upper end of the fabric with the upper roller.
  • the fabric may undergo a slight deformation of curvature due to the action of the wind for example, but this deformation is easily canceled by the longitudinal tensioning exerted by the upper and lower rollers during the winding operation.
  • the invention also covers the variants in which the canvas consists of a relatively inextensible coated fabric.
  • the fixing module can consist of a profile having a groove capable of receiving and retaining a rod mounted on the upper end of the fabric.
  • the fixing module can operate on different principles, while remaining within the scope of the invention.
  • the drop-down mechanism connecting the fixing module to the upper roller may consist of a plurality of straps secured to the upper roller by their first end, and the fixing module by their second end.
  • the straps can be replaced by any equivalent means, and in particular cables.
  • These straps are wound and take place around the upper roller depending on whether the fixing module is lowered for the operation of putting up the poster, or reassembled for winding the canvas on the upper roller.
  • the upper roller has zones of smaller diameter, intended to accommodate straps during the winding of the fabric, so that once wound, the straps do not exceed the main diameter of the roller.
  • the straps are integrated inside a zone provided for this purpose in the upper roller, so that it does not cause any excess thickness on the diameter of the upper roller, which would cause deformations of the fabric during its winding.
  • the upper roller has a housing capable of receiving the fixing module during the winding of the fabric.
  • the fixing module and the housing intended to accommodate it have a geometry such that when the module is in place in said housing, it does not exceed the diameter of the upper roller.
  • the upper roller has a geometry as cylindrical as possible, to allow a regular and uniform winding of the fabric, and not to create folds.
  • the means for keeping the fabric under transverse tension consist of:
  • the fabric is equipped with rods present on its vertical edges by which it cooperates with fixed members integral with the unwinding device.
  • the guidance is obtained by the cooperation of a rod and of a profile forming a slide, but other modes of reahsation can be adopted, such as in particular the use of perforations at the edge of the fabric cooperating with spiked rollers arranged along the path of the side edges.
  • the lateral rod also comes to wind up at the end of the roll, and the additional thickness formed is taken in by the difference in diameter.
  • the ends of the upper and lower rollers are conical.
  • the non-deformable lateral rod provides a certain longitudinal rigidity which avoids the blocking of the fabric during its winding and its excessive deformation.
  • the means for maintaining transverse tension of the fabric are adjustable in width, to allow adaptation to slightly different types of posters, or even to particular atmospheric conditions, for which it is necessary to adjust the limits. acceptable poster distortion.
  • the means for maintaining transverse tension are associated with means making it possible to increase the transverse tension of the fabric when the latter is immobilized.
  • the device comprises means for fixing the four corners of the fabric on the upper and lower rollers.
  • Figure 1 is a summary perspective view of the device according to the invention.
  • Figure 2 is a side view of the device shown during the operation of placing the poster.
  • Figure 3 is a side view of the same device shown when the poster is already wound on the two upper and lower rollers.
  • Figure 4 is a cross-sectional view from above of the same device.
  • the display device by winding and unwinding an information support canvas, referenced D as a whole, comprises two rollers (100, 200) on which is wound and takes place the fabric (300) not shown in FIG. 1.
  • the roller (100) carries a fixing module (110) capable of moving between the two rollers (100, 200).
  • the lower roller (200) comprises, for its part, means for fixing the lower end (320) of the fabric (300).
  • the fixing module (110) of the upper end (310) of the fabric (300) is linked to the upper roller (100) in a removable manner so that the rotation of the upper roller in the direction of the unwinding illustrated by the arrow A, brings the fixing module (110) to the height of the lower roller (200), thus authorizing the installation or the removal of the upper end (310) of the fabric (300).
  • the rotation of the upper roller (100) in the winding direction brings the fixing module (110) in abutment against the upper roller (100) while allowing the rest of the fabric (300) to be wound.
  • Figures 1 and 2 illustrate the device in the situation where the fixing module is located in the low position, near the lower roller (200) to allow the operator the easy installation or removal of the upper end of the Web.
  • the fixing module (110) can advantageously be constituted by a profile inside which can be temporarily trapped a rod (311) integral with the fabric (300).
  • such a profile may for example be of the type described in patent EP 0 294 301, the content of which is incorporated here by reference, so that it will not be necessary to describe in detail.
  • the principle of operation of such a fixing module is based on the cooperation of a swollen part secured to one end of the fabric, with a profile having a groove whose width of the opening is less than the thickness of the swollen part.
  • This profile has a flexible zone (112) allowing the introduction of the bulged part (311) inside the groove, this flexible part (112) being arranged in such a way that it opposes the exit of the bulging part (311) outside the groove.
  • such a profile can constitute the fixing module (110) integral with the upper roller (100), and can also be incorporated in a part of the lower roller (200), so that the groove of the profile constitutes a generator of the roller (200) capable of receiving the lower end of the fabric itself equipped with a characteristic rod.
  • the upper roller (100) comprises at least two fixing straps (400), the upper end (410) of which is linked to the upper roller (100), the lower end (420) of the strap (400) being linked to the fixing module (110).
  • the strap (400) winds and unwinds around the upper roller (100) in order to raise or lower the fixing module (110) in the plane of the fabric.
  • the number of straps (400) is determined according to the width of the fabric.
  • the upper roller (100) has two winding diameters materialized at the level of a first external cylinder (120) and a second internal cylinder (130).
  • the outer cylinder (120) is made up of which one of the sections (121) separated from each other by an inner cylinder section (131).
  • the fabric (300) is wound as illustrated in Figure 3 on the outer cylinder (120), while the strap (400) is wound on the inner cylinder (130).
  • the upper roller (100) comprises a housing (140) intended to receive the fixing module (100), mounted at the ends (420) of the straps (400).
  • the housing (140) has a geometry such that the fixing module (110) is embedded therein so as not to interfere with the winding of the fabric (300), and maintain a geometry as cylindrical as possible, to eliminate surface irregularities that are sources of crease initiation.
  • the length of the fixing strap (400) is determined so that during winding, the fixing module (110) fits into the housing (140) provided for this purpose on the upper cylinder (100 ).
  • the fixing module (110) has an external surface which completes the circumference of the external cylinder (120), interrupted by the longitudinal housing (140) provided to receive the fixing module ( 110).
  • the outer surface (111) of the fixing module (110) is preformed so as to take up the radius of curvature of the space created by the presence of the longitudinal housing (140). Thanks to this arrangement, the upper roller (110) therefore remains cylindrical, and the zones of smaller diameter (131) separating the different sections (121) of the outer cylinder (120), are filled by the fixing module (110).
  • the fixing strap (400) also has a thin covering sheet (421 ) on its lower end (420).
  • This thin sheet (421) has a thickness such that the latter fills, by being rolled up, the part of zone of smaller diameter (131) separating the different sections (121) constituting the outer cylinder (120) not filled by the module fixing (110).
  • the upper cylinder (100) has a perfectly regular and cylindrical geometry, which eliminates almost all of the risk of the appearance of folds.
  • the upper and lower rollers (100, 200) can be produced from the same profile, the lower cylinder (200) comprising a housing in which is permanently mounted a profile identical to that of the module. fixing (110).
  • the device also includes means for keeping the fabric under transverse tension.
  • These means can be constituted, on each side of the fabric (300), by a fixed slide (500, 501) comprising a groove (510) directed towards the fabric (300), and inside which slides a rod (340) secured to an edge (350) of the fabric (300).
  • the lateral slide (500) has a groove (510) whose opening is less than the diameter of the rod (340) secured to the edge (350) of the fabric.
  • the invention also covers alternative embodiments in which the slide and the housing illustrated in FIG. 4 are replaced by other means making it possible to force the edges of the fabric to travel a determined trajectory.
  • This slide (500) can advantageously be made with a material having a low coefficient of friction relative to the lateral rod (340), to limit the phenomena of friction.
  • the lateral rod (340) is made so as to be relatively undeformable longitudinally, so that the forces exerted by the traction of the upper roller (100) are transmitted to the lower part of the fabric, to counter thus friction phenomena, and avoid elongation of the edge.
  • the lateral slides (500) have a wider opening area in the upper and lower parts to facilitate the introduction of the rod (340) and the positioning of the fabric.
  • the upper roller (100) has, at its lateral ends, zones (150) of smaller diameter, advantageously conical, to collect the excess thickness formed by winding the lateral rod.
  • the upper (100) and lower (200) rollers each comprise a drive means independent of each other, ensuring the tension by reverse rotation when the fabric ( 300) does not scroll, and accelerating or slowing down the speed of rotation depending on the thickness of the fabric (300) wound on each roller (100) and (200).
  • the electronic and computerized management of the speed of rotation of the rollers makes it possible to avoid the use of additional modules for tensioning the fabric integrated into the rollers, modules existing in the prior art, but difficult to adapt to the training of support fabric very large information.
  • the rollers (100) and (200) rotate in the same direction, with a speed difference managed by a central unit taking into account the number of rotations already carried out; the two upper (100) and lower (200) rollers stop when the poster or the information present on the canvas (300) is in the display window;
  • This last step is particularly advantageous in the preferred case where the canvas is made of an extensible plastic material, since the flatness of the canvas is then perfectly ensured.
  • the electronic and computerized management of the training also makes it possible to carry out certain automatic operations.
  • the detection of canvas ends can be used to calculate, by means of the central unit or an equivalent automaton, the length of the canvas, consequently the number of posters to be presented.
  • the device according to the invention allows an optimal display of information support fabrics having very varied formats.
  • Such a device is particularly suitable for large format displays, from 12 m 2 up to formats up to 14.5 m wide by 4.5 m high, or even more.
  • Such a device is perfectly suited for outdoor exposure, since the maintenance of the canvas on its four sides makes it easy to withstand variations in atmospheric conditions.
  • Such a device is therefore particularly wind resistant, but it can also be mounted in closed display cases forming a box, possibly backlit.
