(54) Link chain for retractable screens


(57) Link chain for retractable screens for easy assembly which has limited the direction of the rotation thanks to a first flange (2), located on the rear top of the links (1) and a second flange (6), located on the front top of the links (1) such that when both flanges come into contact they avoid the link chain to rotate in that direction. Also the links (1) incorporate a vertical step (5) on its inner side by which a inclined vertical side (7) of an adjacent link slides in such a way that the chain can only be rotated a certain angle marked by the contact of the inclined vertical side (7) of a link and the vertical step (5) of the adjacent link. Links (1) include a front limit surface (10) and a rear limit surface (11), which are flexible in order to facilitate the assembly of the chain.
