Definitions

  • the present invention relates to the field of display panels and in particular to the adaptations allowing to realize the dynamic display in the best conditions.
  • French Patent No. 2,712,719 proposes a display panel which, highlighting work such a method uses a support tape of at least one message taking place from a first roll to wind on a second roll, and vice versa.
  • the rollers are intermittently rotated at constant speed by an electric motor by means of a toothed pinion / toothed belt transmission transmitting the movement of rotation to pulleys (preferably toothed) mounted at each end of the rollers
  • pulleys preferably toothed
  • One of the rollers is provided, arranged between the pulley and its mandrel. a device ribbon tensioning and peripheral relative speed compensation depending on the amount of ribbon wound or unwound on the roll.
  • This feature has the advantage of facilitating loading operations and tape unloading which can therefore be carried out quickly and in optimal conditions because the roll can be prepared before installation in situ, so that the installer will be better able to meet the alignment constraints required a ribbon display device.
  • the above tensioning device of the display device is disposed between the drive pulley of said support roller and one end of the latter provided with removable hooking means on said tensioning device.
  • the support roller is fixed to a tensioning device independent associated with the pulley, which has for primary interest to simplify the realization of the support roll and therefore to manufacture it at a lower cost. It is therefore particularly indicated for mass production, in particular for each ribbon to be installed which will be installed from such a roller.
  • the second roller, called deflection roller, of the display device consists of a cylindrical tube crossed by a rotation shaft at a first end of which is linked the pulley for driving said deflection roller
  • the connection between the shaft and the roller is flexible to allow slight angular expansion in the rotational movement of said roller.
  • the alignment of its ribbon is not always perfect.
  • Conditions conditions may change the mechanical characteristics of specific areas of the tape which, after several windings and successive unrollings around the rollers can lose alignment and not offer messages in the best conditions advertising (crumpled posters) or shift the markers for programming the panel and thus put it out of service.
  • the flexible connection existing between the above roll of reference and its shaft overcomes this major drawback by leaving some angular freedom with the roller. This angular freedom makes it possible to make up for differences any alignment that may occur during the operation of such a device display.
  • the deflection roller has at least two pins aligned on a same generator of the cylinder constituted by the deflection roller, and on which comes place the free end of the ribbon fitted with two corresponding eyelets, thus making even easier to install the ribbon.
  • Figure 1 is a partial sectional front view of the display device of the invention.
  • Figure 2 is a detailed perspective view of an organ of this device.
  • Figure 3 is a detailed perspective view of another member of this device.
  • the roll 200 said support roll comprising the wound ribbon around, is removably mounted relative to its drive pulley 210 and to the frame 100 so that the ribbon R can be wound entirely on said roll 210 before its installation on the frame.
  • the above tensioning device 400 of the display device D is disposed between the drive pulley 210 of said support roller 200 and one end 200a thereof provided with hooking means removable on said tensioning device 400.
  • the above tensioning device 400 of the display device D consists of a coil 420 external collar 430 internally receiving the coaxial spring 410 to said roller 200, a first of which end of said spring 410a is integral with pulley 210 and the second end of which 410b is integral with the coil 420.
  • the outer surface of the above coil 420 with collar 430 has at its base a cylindrical shape 421 which constitutes the support bearing of the aforesaid roller 200 which is fitted thereon and at its end a frustoconical shape 422.
  • the conical end 412 has the advantage of centering the roller 200 on the bearing 421 during assembly and to facilitate its release during disassembly.
  • This coil 420 is pivotally mounted around a shaft 110 retained on the frame 100 of the device and around which the pulley 210 rotates.
  • plate 500 places roller 200 on the flange outside 430 of the coil 420 which, as illustrated in the drawing of FIG. 2, is knurled on its outer cylinder 431.
  • the aforesaid deflection roller 300 is a cylindrical tube crossed by a rotating shaft 600 a first end 600a of which is linked to the drive pulley 310 of said roller return 300, the connection between the shaft 600 and the roller 300 being flexible to allow a slight angular expansion in the rotational movement of said roller 300 in the plane common passing through the two axes of rotation of the rollers 200 and 300.
  • This rotating shaft 600 is pivotally mounted relative to the frame 100 on two bearings 140 and 150.
  • the flexible connection between the rotating shaft 600 and the roller reference 300 allowing a slight angular expansion is ensured on the one hand, by a central crown 700 admitting a slight bending and whose outer surface forming a shoulder 710 is fixed inside the roller 300 and the inner surface of which forms a shoulder 720 is fixed to the rotating shaft 600, and on the other hand, by a bearing 320 which, coaxially attached to the second end 300b of said deflection roller 300, to a diameter interior large enough to allow some angular freedom in movement of rotation.
  • the central ring 700 has an outer shoulder 710 which is fixed in the inner cylinder of the roller 300 and an internal shoulder 720 which is fixed on the rotating shaft 600.
  • the crown 600 admits a large amplitude bending to allow a angular expansion of the rotational movement of the roller 300 thus ensuring auto tape centering by making up for its alignment losses.
  • the flexibility of the 700 crown is improved by drilling holes 740 in its surface 730 perpendicular to its axis.
  • the angular expansion is advantageously controlled by the internal diameter of the bearing 320 which, when the angle is too large, abuts on the second end 600b of the rotating shaft 600.
  • the ribbon display device which has just been above described and shown, was for disclosure rather than limitation. Good of course, various adjustments, modifications and improvements could be made to the example above, without departing from the scope of the invention taken in its aspects and in his broadest mind.
  • the bearing 320 housed at the end 300b of the deflection roller 300 may have a shoulder which will move in a oblong hole made so as to limit the angular expansion of the rotational movement of the roller 300 in a plane passing through the axes of rotation of the two rollers 200 and 300.
