Abstract
Electromechanical or manual vertically-moving roller curtain for windows in general consisting of a curtain (1) made of thin and flexible material, wrapped around a self-winding upper roller (2) and having its lower edge fastened to a rigid horizontal crossbar (4) connected, in its turn, by links (5), to sliders (6) equipped with matching internal thread, consisting of vertical worm screws (7) provided with matching thread meshing with the internal threads of the sliders (6), a geared motor (8) or a crank driving the worm screws (7) through the driven shaft (9) and through bevel gear pairs (10), and including a surrounding frame (11, 17) consisting of vertical and horizontal section bars connected by linkage (14, 15, 16) so that when the motor (8) or the crank is driven, a rotation is imparted to the worm screws (7) which, through sliders (6), vertically move the lower edge of the curtain (1) which is moved upwards and downwards thus winding and unwinding on the upper roller (2).
Description
- 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.
- Such 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. 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.
- Such arrangement has some drawbacks. 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.
- These well-known vertically-moving curtains may also be electromechanically controlled, but in case of failure or malfunctioning of this electromechanic drive, the curtain cannot be operated manually and again becomes useless.
- It should be mentioned that there are also blinds consisting of horizontal interconnected strips, with side guides and electromechanic drive, these strips being stacked in the upper area when the blind is open while they are distributed on the window surface when the blind is closed. These strip blinds have the drawback that the failure of even one only of the strip links blocks the blind and makes it useless.
- It may also be observed that there are horizontally-moving curtains with vertical folds but their great drawback is that, particularly in rail passenger-cars, they tend to flap and become tattered when used with open windows.
- 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.
- In the invention in question 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. At its upper end 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 invention in question is illustrated in one exemplifying implementation in the enclosed drawings, in which:
- Fig. 1 shows a front view and partial section of the curtain subject matter of this invention and relevant frame,
- Fig. 2 shows the cross section according to the X-X axis of the curtain in Fig. 1,
- Fig. 3 shows a magnified front view of the junction of the section bars forming the curtain frame,
- Fig. 4 shows the longitudinal section of the frame according to the Y-Y axis in Fig. 3,
- Fig. 5 shows a cross section of the frame according to the Z-Z axis in Fig. 3.
- With reference to the above drawings, 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 mentionedcurtain 1 is fixed to the self-winding roller 2, while the lower edge is fastened, by means of stiches or seams, to ahorizontal crossbar 4 of any suitable shape, such as strip or rod, etc., in rigid material, such as metal or hard plastic. - At each end of the
above crossbar 4 aredetachable links 5 connected to thesliders 6, with internal matching thread, meshing withvertical worm screws 7 with matching threads. A geared motor 8 simultaneously drives theworm screws 7 by means of a drivenshaft 9 andbevel gear pairs 10 which may reduce the gear ratio. - Basically, by operating the geared motor 8 in either direction, the
worm screws 7 will rotate in one direction or in the opposite one and cause raising or lowering of the threadedsliders 6 which, connected to thelower crossbar 4, will push the lower edge of thecurtain 1 up or down. - When
curtain 1 is pulled down to cover thewindow 19, it will unwind from the upper roller 2 overcoming the opposing action of spring 3, while when it is pulled upwards it will automatically wind on the roller 2 under the action of the winding spring 3. - The matching threads of the
worm screws 7 and ofsliders 6 have a wide lead angle β 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. - By such hand-operation, the elctromechanic system is dragged and its inertial resistance keeps the curtain in the chosen position.
- It follows that, in accordance with the aims of this invention, the sliding curtain gently opens and closes with balanced control without the possibility of getting stuck and with stable positioning.
- In the exemplifying solution described and illustrated in the drawings 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 thebevel gear pairs 10 in theupper 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 aslot 12 facing inwards. Inside each of the mentioned box-type sections 11 are placed aworm screw 7 andrelevant slider 6, while theslot 12 allows passage and sliding of thelink 5 connecting thecrossbar 4 of thecurtain 1. The box-type section 11 has theshape 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 moresmall plates 14 fitted withset screws 15 of theexternal junction plate 16. The above fastening system withplate 16 connects theposts 11 to thecrossbars 17. - To secure the frames in site, 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.
- Obviously the geared motor 8 can be substituted by a crank so that the curtain is operated by hand.
