Abstract: Movement device (A), for at least one lighting source (I) which allows it to move up and down, including at least one housing (2) with at least an anchoring bracket (1) to the ceiling or like, the housing including an unrolling/rolling arrangement of a band (4) which connects the housing itself (2) to the lighting source (I) and which causes the mentioned movement up and down and a power supply for the lighting source by way of the band.

Abstract: A window regulator includes a threaded shaft (20) arranged at the concave side of the window (16) and extending in the direction of sliding of the same window, a nut screw (24) engaging the threaded shaft (20), which is movable up and down along the shaft, a driving member (26) fastened to a lower zone of the window (16), and a member for interconnecting the nut screw (24) and the driving member (26), adapted to ensure the interconnection of the driving member (26) and the nut screw (24) independently of their distance. The interconnection member includes at least a rigid connecting rod (36; 36a) articulated on one side to the nut screw (24) and on the other side to the driving member (26), which is able to assume different tilts when the distance between the driving member (26) and the nut screw (24) changes.

Abstract: A window regulator comprises a threaded shaft (20) arranged at the concave side of the window (16) and extending in the direction of sliding of the same window, a nut screw (24) engaging the threaded shaft (20), which is movable according a to-and-fro movement along the shaft, a driving member (26) fastened to a lower zone of the window (16), and means for interconnecting the nut screw (24) and the driving member (26), adapted to ensure the interconnection of the driving member (26) and the nut screw (24) independently of their distance. The interconnection means comprise at least a rigid connecting rod (36; 36a) articulated on one side to the nut screw (24) and on the other side to the driving member (26), according to an arrangement such as to assume a variable configuration when the distance between the driving member (26) and the nut screw (24) changes.

Abstract: Electromechanical or manually operable vertical-moving roller curtains for windows which consist of a curtain made of thin and flexible material, wrapped around a self-winding upper roller and a lower edge fastened to a rigid horizontal crossbar. The crossbar is connected by vertical worm screw linkages to sliders. The worm screws and sliders have a matching thread meshing for driving connection therebetween. A geared motor or a crank drives the worm screws through a drive shaft and through bevel gear pairs. A surrounding hollowed frame consists of vertical and horizontal section bars, connected by linkage so that when the motor or crank is driven a rotation is imparted to the worm screws which, via sliders, vertically move the lower edge of the curtain upwards or downwards, thereby winding and unwinding the curtain on the upper roller.

Abstract: Electric safety-lock consisting of a motor (3) which by means of movement reduction gears (4, 5) drives a worm screw (6) axially mounted on the driven wheel (5). A slider (8) is keyed onto the worm screw (6) on which the mobile lock studs (9) entering the holes (10) in the locking box (1) are fastened. A mobile rack (13) is mounted on the slider (8); the rack (13) may be operated in case of emergency by a gear wheel (14) meshing with a cylinder or sprocket latch (17) and functioning when using a key (15) or knob. An electric circuit provided with sensors (24, 25, 26) provides for remote control (34) of the door lock via opening (A) and closing push-buttons (C). The safety-lock may also be equipped with an alarm system.
