Embodiment Construction

[0054] figure 1 A blind arrangement 1 or a projection screen arrangement 1 arranged on a frame 10 is shown in a transverse sectional view, which is represented according to a first embodiment of the invention. The curtain or projection screen arrangement 1 comprises a movable curtain with a rollable shade 2 and an electric operating device 100 for operating the rollable shade 2 . The shade is fixed to the frame by means of second fixing means 3 for fixing the upper end of the shade.

[0055] Electrically operated devices include:

[0056]- a winding tube 4 movable around a first axis X1-X1', on which the curtain is intended to be wound,

[0057] - the actuator 5, which is arranged at least partially in the winding tube,

[0058] - A first fixing part 6 for fixing the first end of the screen to the winding tube.

[0059] Electric means are used to connect to the frame 10 only through the curtain. In particular, motorized means are used for suspension only through the curt...

Abstract

Electric operating device (100; 100'; 100'' ), movable curtain with a rollable cord (2) for operating a curtain or projection screen device (1; 1'; 1''), an electric operating device for suspension via a cord and comprising: winding tube (4), The coiled tube can move around the first axis (X1-X1'), the cord is used to wind to the coiled tube; the actuator (5), which is at least partially arranged in the coiled tube; the first end of the cord is fixed to the first fixed part of the coiled tube (6,6a), the weight of the electric operating device generates the unfolding torque of the cord, which is characterized in that the electric operating device comprises a compensation component for the unfolding torque (6b,7,7',7',8,9a,9b), which is only by combining with gravity and / or interact with the cord.

Description

technical field [0001] The invention relates to movable curtains of the curtain or projection screen type with rollable shades, equipped with motorized roll-up means, wherein the motorized roll-up means move vertically when the roll-up means are electrically actuated. More precisely, the invention relates to a motorized operating device for a movable curtain with a rollable shade for operating a curtain or projection screen arrangement, and to a curtain or projection screen arrangement comprising such an operating device. Background technique [0002] In US Pat. No. 7,089,991 a movable curtain with a rollable curtain is described. Synchronous drive elements arranged at both ends of the load bar cooperate with rails equipped with racks. The curtain is fixed on the load bar through the first end, and fixed on the winding pipe through the second end, and the winding pipe is equipped with a winding spring and is arranged in the upper box. [0003] This arrangement requires two...
