Abstract
The curtain comprises two fixed guides 10, parallel to the direction of sliding of the free edge 3 of the screen 2, with two distinct longitudinal surfaces 11 and 12 oriented in opposite directions to each other; to each guide 10 is attached a locking device 20, sliding along the guide 10, with two distinct portions 21 and 22 at a distance apart permitting each of them to come into contact, with friction, at the same time, with an associated longitudinal surface 11, 12; the two portions in contact 21 and 22 and the two longitudinal surfaces 11 and 12 are in such a geometrical relationship with each other that rotation in one direction or the other of the locking device 20 causes the two parts in contact 21 and 22 to move closer together or further apart respectively with respect to the associated longitudinal surfaces 11 and 12; the devices 20 are fixed to a rigid part 40 to which the free edge 3 is attached; the part 40 is subjected to a force F, P that is applied at a point 42 distant from the axis of rotation A of the locking device 20 and such as to cause a moment that turns the locking device 20 so as to bring the said two portions 21 and 22 into contact with the associated longitudinal surfaces 11 and 12 and to exert pressure in the direction of this contact. <IMAGE>
