Definitions

  • the invention relates to a roller shutter lifting-winding friction device.
  • Roller shutter winding-lifting devices manually operated by belt or by rotating bar are well known in prior art. Said devices are generally used for lifting and winding roller shutters or blinds.
  • Belt operated devices are very bulky as they utilize a winding belt device generally separated from the winding drum coaxially placed with respect to the roller shutter winding bar; furthermore, the utilization of an independent winding belt device requires a separate installation with an expensive hole on the wall; not to mention that the belt breaks frequently, involving a considerable amount of work for its replacement.
  • rotating bar operated devices are extremely expensive for their complexity and the rotating bar is also very bulky; furthermore, the lifting and lowering speed is inevitably very slow, due to the transmission means.
  • the invention as claimed is intended to provide a remedy. It solves the problem of how to carry out a new roller shutter winding-lifting device for winding a roller shutter by means of a winding bar, which obviates said disvantages, utilizing a manual endless chain as driving means to operate a rotatable toothed driving pulley coaxially placed at one end of said winding bar, said pulley comprising an automatic free multi-plate clutch ratchet wheel that in the winding direction is driven by said chain fixedly connectable to said winding bar and freely rotatable in the opposite direction and wherein the transmission to the winding bar is preferably realized by an axial reduction gear transmission means with planetary gears, wherein said chain operated pulley is connected to said transmission by means of a screw clutch in such a way that the friction clutch is tightened in one direction determining a single block for winding the roller shutter and in the opposite direction the screw connection is unscrewed releasing the clutch and loosening the roller shutter winding bar allowing the relative unwind
  • the advantages offered by the invention are mainly that belts are not utilized, avoiding the frequent breakages and replacements, and also avoiding separate bulky winding belt devices and expensive holes for their installation on the wall.
  • the device according to the invention is very cheap and extremely reliable and can be utilized for lifting also very big and heavy roller shutters due to its gear reduction means which operate only in the lifting action, being this one automatically disengaged when the toothed driving pulley is rotated in the opposite direction, allowing the desired and controlled lowering of said roller shutter.
  • the figures show the roller shutter lifting-winding device comprising in its basic design: a driven rotating plate with freely rotatable planetary gears assembly “A”; a driving toothed pulley with free ratchet wheel multi-plate friction clutch assembly B” ; a mounting plate “C” for mounting the complete device on the wall; a fixed rim gear wheel “D” for gearing said planetary gears 1 of the driven rotating plate assembly "A” for supporting a winding bar for said roller shutter 2.
  • the driven rotating plate “A” consists of a metallic plate disc 3 with reinforcing ribs 4 further comprising an axial welded connecting pipe with squared interior section 5 for fixed connection with the end of a winding bar (not shown) for winding the roller shutter 2; furthermore, on the opposite side, said metallic plate disc 3 supports simmetrically welded, radially placed at 120° one from the other, at the same distance from the centre, three sleeves 6 which support coaxially three free rotatable planetary gears 1, and further, coaxially inside the pipe connection 5, said disc 3 has an axial central hole 7 for fixing the whole device by means of a central tightening pin 8, as shown in Figure 4.
  • Said driven rotating plate assembly "A” is coaxially insertable within said rim gear “D” as shown in Figure 4, to realize a planetary transmission as shown in Figure 2.
  • the rim gear wheel “D” is preferably made in plastic material and presents an internal toothed rim 9 for gearing with said planetary gears 1, being said rim gear “D” provided with a suitable axial hole 10 to allow the crossing of an axial driving central pinion 14 of said driving toothed pulley assembly "B".
  • the driving toothed pulley with free ratchet wheel multiplate friction clutch assembly “B” comprises a plastic driving pulley 11 with periferical teeth 12 for engaging all endless multisphere chain 13, which allows the clockwise or counter-clockwise rotation of said pulley.
  • the pulley 11 is thus free to rotate clockwise or counter-clockwise, manually driven by the chain 13, being said pulley 11 provided with an axial thread to receive an axially sliding central pinion 14 for centrally gearing with said three planetary gears 1, as shown in Figures 2,4 and 8.
  • the pinion 14 generally made in plastic material, makes one body with a first abutment comprising a two, three or four- start thread 15 cooperating with a similar thread of the axial hole of the driving pulley 11, in such a way that pulling the chain 13 on the side 13' of Figure 1 the driving pulley 11 rotates clockwise, and rotating counter-clockwise it screws on the thread 15 of the support pinion 14 tightening against a suitably provided flange shaped abutment 14' by means of the ratchet ring 19.
  • the driving pulley 11 On the outside the driving pulley 11 has a cylindrical seat 16 forming an annular groove and supports, annularly connected with rotation pins 17, three ratchet gear toothed springs 18 cooperating with the ring 19, free to rotate oil the support pinion 14 and supplied with a free wheel peripheric toothing controlled by the ratchet gear springs 18 for allowing the free rotation of the free rotatable ring 19 clockwise but not counter-clockwise.
  • the driving pulley 11 is free to move axially against the surface of said toothed rim "D", a slack 27 being provided with respect to the support pinion 14,14'; therefore, rotating clockwise the driving pulley 11, that is pulling the chain portion 13" of the driving chain 13, this one will unscrew from the thread 15 with the support pinion 14 moving axially to the left and unclutching the friction annular plates 20,21 and the free rotatable ring 19, thus allowing the rotation of said free rotatable ring 19 that will no longer lock the support pinion 14, which will thus be free to rotate and will slide in rotation by means of the weight of the roller shutter 2, allowing the controlled clockwise rotation of the roller shutter support rotating disc “A”, allowing the speedy lowering of the roller shutter 2 in the desired quantity, because, if the driving pulley 11 rotation is stopped by stopping the pulling of the chain portion 13" of the chain 13, the same unwinding force impressed by the weight of the roller shutter 2 to a driven plate "A" makes the pinion 14 rotate
  • the driving pulley 11 is restricted in its axial movement as regards the pinion 14 due to the inside ledge which prevents its slipping off by means of an elastic ring 28.
