Definitions

  • Roller curtains fitted with vertical motion so as to cover partially or totally the inside of a window or door-window pane are commonly known.
  • roller curtains are used for house windows or windows of rail passenger-cars, coaches, industrial vehicles, watercraft and boats, etc. and generally feature a panel of thin flexible material, such as fabric, plastic or other suitable material, which, by sliding, partially or totally covers the windowpane.
  • a panel of thin flexible material such as fabric, plastic or other suitable material, which, by sliding, partially or totally covers the windowpane.
  • Such panel is at present operated by hand and features at its lower edge sliders, guided by grooves located in the opposite internal sides of the door or window frame.
  • a first drawback is that these hand-operated roller curtains usually do not take and maintain a stable position and autonomously vary their coverage, especially in train passenger-cars and vehicles subject to strong vibrations.
  • a second drawback is due to the fact that during the operation, sometimes carried out without great delicacy, the side guide sliders may get stuck thus blocking the movement of the curtain or slip out of their ways thus making the curtain useless, and making the user uncomfortable and dissatisfied.
  • the invention in question presents a panel-type roller curtain in thin and flexible material with electromechanical or manual vertical movement, capable of eliminating the drawbacks of the above mentioned known curtains.
  • the curtain is operated at both lower ends by a system of sliders and corresponding worm screws, both worm screws being controlled by one single electric geared motor through driving gears.
  • the curtain is wrapped around a self-winding roller, which automatically rewinds the curtain and applies a pulling force which prevents flapping and tattering.
  • the worm screws and corresponding sliders show threads with high lead angle to the horizontal plane, so that the curtain may be manually operated in case of failure of the electromechanic driving mechanism, which in such case is dragged by hand.
  • the thin panel-like curtain 1 in flexible material such as fabric, plastic or other suitable material is wrapped around a rotating roller 2 fitted with axial spring 3 for self-winding.
  • the upper edge of the above mentioned curtain 1 is fixed to the self-winding roller 2, while the lower edge is fastened, by means of stiches or seams, to a horizontal crossbar 4 of any suitable shape, such as strip or rod, etc., in rigid material, such as metal or hard plastic.
  • detachable links 5 connected to the sliders 6, with internal matching thread, meshing with vertical worm screws 7 with matching threads.
  • a geared motor 8 simultaneously drives the worm screws 7 by means of a driven shaft 9 and bevel gear pairs 10 which may reduce the gear ratio.
  • the worm screws 7 will rotate in one direction or in the opposite one and cause raising or lowering of the threaded sliders 6 which, connected to the lower crossbar 4, will push the lower edge of the curtain 1 up or down.
  • the matching threads of the worm screws 7 and of sliders 6 have a wide lead angle ⁇ with respect to the transverse horizontal plane, so that, in case of failure or missing of the electromechanic drive, the curtain may be operated manually with reversible driven motion.
  • the sliding curtain gently opens and closes with balanced control without the possibility of getting stuck and with stable positioning.
  • the electromechanic control system is located in the lower part of the window, but it is also possible, according to this invention, to locate this control system in the upper part of the window by placing the driven shaft 9 of the geared motor 8 inside the shaft of the self-winding roller 2 and by locating the bevel gear pairs 10 in the upper boxes 20 acting as supports for the self-winding roller 2.
  • the curtain as described above features a surrounding frame which makes it particularly functional and well structured.
  • the side posts will preferably consist of box-type sections 11 featuring a slot 12 facing inwards. Inside each of the mentioned box-type sections 11 are placed a worm screw 7 and relevant slider 6, while the slot 12 allows passage and sliding of the link 5 connecting the crossbar 4 of the curtain 1.
  • the box-type section 11 has the shape 13 of a channel section on one side, normally on the inner side of the window, with inward facing flanges, suitable to house one or more small plates 14 fitted with set screws 15 of the external junction plate 16.
  • the above fastening system with plate 16 connects the posts 11 to the crossbars 17.
  • the lower crossbar 17 may have the shape of a double channel section, as shown by way of example in Fig. 2.
  • the vertical 11 and horizontal framing sections 17 may of course have different shapes, and also their connecting system may be different.
  • the invention in question may also be used as an independent mosquito-net or in combination with the curtain where such mosquito-net in thin and flexible net is wound on the self-winding roller 2 and operated by the described elctromechanic system.
  • geared motor 8 can be substituted by a crank so that the curtain is operated by hand.
