Definitions

  • the invention relates to the display industry and more specifically to animated display sector operating by the unfolding of a canvas comprising several panels juxtaposed. It relates more particularly to a structure a scrolling display device, which allows the use of posters very large format, which can be used especially 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.
  • These two rollers are actuated to ensure movement of the strip, and a stop thereof allowing the display area to coincide with the display case.
  • the posters used in this type of device consist of panels connected prints to constitute the poster itself.
  • the folds constitute the extra thicknesses at the winding of the band, which can cause deformation or blockage of the system winding.
  • Such devices are distributed at the edge of the land so as to be in the field of television broadcast cameras, and the unwinding mechanism the poster is activated as and when retransmission, depending on the rental of advertising space.
  • Such devices Because of their exposure to shock risks, such devices must be able to withstand significant efforts, and are therefore relatively large modest. More generally, such devices are equipped with a solid panel installed at the rear of the information carrier, and intended to ensure its rigidity for bear the impacts.
  • the objective of the invention is to provide a display device which can be declined in a multiplicity of formats, in particular in large dimensions, while being able to withstand phenomena atmospheres likely to distort the poster and cause the formation of folds, particularly detrimental to the quality of the winding.
  • the invention therefore relates to a display device by unwinding of a canvas information carrier, in which the canvas wraps and unwinds around two motorized rollers synchronized, so that the fabric is held under tension during its unfolding.
  • the setting in place of the poster around the drive rollers is done at a specific element, mechanically separable from the upper roller, to facilitate installation operations by bringing this fixing module closer to the area bottom of the roll-down panel, i.e. near the bottom roller.
  • the actuation of the upper roller therefore ensures the ascent of the module fixing and securing the upper end of the canvas with the roller superior.
  • the fabric may undergo a slight deformation of curvature due to wind action for example, but this deformation is easily canceled by the longitudinal tension exerted by the upper rollers and lower 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 canvas.
  • the fixing module can operate on different principles, while remaining within the scope of the invention.
  • the drop-down mechanism connecting the module attachment to the upper roller may consist of a plurality of straps integral with the upper roller at their first end, and the fixing module by their second end.
  • the straps can be replaced by any means equivalent, including cables.
  • These straps are wrapped and unwound around the upper roller depending on whether the fixing module is lowered for the poster placement operation, or reassembled for winding the canvas on the upper roller.
  • the upper roller has zones of smaller diameter, intended to accommodate straps when winding the canvas, so that once wrapped, the straps do not exceed the diameter main roller.
  • the straps integrate inside an area 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 canvas during its winding.
  • the upper roller has a housing capable of accommodating the fixing module during the winding of the fabric.
  • the fixing module and the housing intended for 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 create a fold start.
  • the canvas is equipped with rods present on its borders vertical by which it cooperates with fixed members integral with the device of unfolding.
  • the guidance is obtained by the cooperation of a rod and of a profile forming a slide, but other embodiments can be adopted, such as in particular the use of perforations at the edge of the canvas cooperating with spiked rollers arranged along the path of the side edges.
  • the end of the upper and lower rollers is of smaller diameter, so as to receive the additional thickness formed by the winding of the side rod.
  • the ends of the upper rollers and lower are conical.
  • the fabric used is advantageously elastic, the side rod non-deformable ensures a certain longitudinal rigidity which prevents blocking of the canvas during its winding and its excessive deformation.
  • the means for maintaining tension transverse of the fabric are adjustable in width, to allow adaptation to slightly different types of posters, or even with conditions particular atmospheres, for which it is necessary to set the limits acceptable poster distortion.
  • the means for maintaining tension transverse are associated with means for increasing the tension transverse of the fabric when the latter is immobilized.
  • the device comprises means fixing the four corners of the fabric on the upper and lower rollers.
  • the winding display device and unfolding of an information support canvas, referenced D as a whole has two rollers (100, 200) on which the fabric is wound and unwound (300) not shown in Figure 1.
  • the roller (100) carries a fixing module (110) capable of moving between the two rollers (100, 200).
  • the lower roller (200) has, 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 removably linked to the upper roller (100) in such a way that the rotation of the upper roller in the direction of unwinding illustrated by arrow A, brings the fixing module (110) to the height of the lower roller (200), thus authorizing the installation or 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) pressing against the upper roller (100) while authorizing the winding of the rest of the fabric (300).
  • FIGS 1 and 2 illustrate the device in the situation where the module fixing 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 canvas.
  • the fixing module (110) can advantageously be constituted by a profile inside which can be temporarily imprisoned a rod (311) integral with the fabric (300).
  • such a profile can for example be of the type described in patent EP 0 294 301, the content of which is incorporated here by reference, so which it will not be necessary to describe in detail.
  • the principle of operation of a such a fixing module is based on the cooperation of a swollen part secured to a 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 bulging part (311) inside the groove, this flexible part (112) being arranged in such a way that it opposes the exit of the bulged part (311) to outside the throat.
  • such a profile can constitute the module for fixing (110) integral with the upper roller (100), and can also be incorporated in part of the lower roller (200), so that the groove of the profile constitutes a generator of the roller (200) capable of receiving the end lower of the canvas itself equipped with a characteristic rush.
  • the upper roller (100) has at least two fixing straps (400) whose upper end (410) is linked to the roller upper (100), the lower end (420) of the strap (400) being linked to the module fixing (110).
  • the strap (400) winds and unwinds around the upper roller (100) so 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 a first outer cylinder (120) and a second inner cylinder (130).
  • the outer cylinder (120) is made up of which one of the separate sections (121) between them by an inner cylinder section (131).
  • the canvas (300) is wound up as illustrated in FIG. 3 on the cylinder outside (120), while the strap (400) is wound on the inside 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 to do not interfere with the winding of the fabric (300), and keep a geometry also cylindrical as possible, to eliminate surface irregularities that are sources of folds.
  • the length of the fixing strap (400) is determined so that during winding, the fixing module (110) is embedded in the housing (140) provided for this purpose on the upper cylinder (100).
  • the fixing module (110) has an outer surface which completes the circumference of the cylinder outside (120), interrupted by the longitudinal housing (140) provided for 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 roller upper (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 strap fixing (400) also has a thin covering sheet (421) on its end low (420).
  • This thin sheet (421) has a thickness such that the latter fills, while being rolled up, the part of zone of smaller diameter (131) separating the various sections (121) constituting the outer cylinder (120) not filled by the module fixing (110).
  • the cylinder upper (100) has a perfectly regular and cylindrical geometry, which virtually eliminates the risk of wrinkles.
  • the upper and lower rollers (100, 200) can be made from the same profile, the lower cylinder (200) comprising a housing in which is permanently mounted a profile identical to that of the fixing module (110).
  • the device comprises also means for keeping the fabric under transverse tension.
  • These means can be formed, on each side of the fabric (300), by a fixed slide (500, 501) having a groove (510) directed towards the fabric (300), and inside which slides a rod (340) integral with a edge (350) of the canvas (300).
  • the lateral slide (500) has a groove (510) of which the opening is less than the diameter of the rod (340) integral with the edge (350) of the Web.
  • the invention also covers alternative embodiments in which the slide and the housing illustrated in FIG. 4 are replaced by other means of forcing the edges of the canvas to cover a determined trajectory.
  • This slide (500) can advantageously be made with a material having a low coefficient of friction compared to the lateral rod (340), for limit friction phenomena.
  • 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 up to part canvas, to counter friction phenomena, and avoid the elongation of the edge.
  • the side rails (500) have a wider opening area in the upper and lower parts to facilitate insertion of the rod (340) and the positioning of the canvas.
  • the upper roller (100) has, at its lateral ends, zones (150) of lesser diameter, advantageously conical, to collect the excess thickness formed by the winding of the side rod.
  • the rollers upper (100) and lower (200) each comprise a drive means independent of each other, ensuring tension by reverse rotation when the fabric (300) does not scroll, and accelerates or decelerates the next rotation speed the thickness of the fabric (300) wound on each roll (100) and (200).
  • 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 insured.
  • the electronic and computerized management of the drive also allows to perform certain automatic operations. So, for example, the detection of ends of canvas can be used to calculate, using the central unit or a PLC equivalent, the length of the canvas, consequently the number of posters to present.
  • the device according to the invention allows an optimal display of information support fabrics presenting 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 support the variations in weather conditions.
  • Such a device is therefore particularly wind resistant, but it can also be mounted in closed cases forming a box, possibly backlit.
