<p>Link chairs, for retractable screens for easy assembly which has limited the angle of the rotation thanks to a first protrusion (2), located on the rear top of the links (I) and a second protrusion (6), located on the front top of the links (I) such that when both protrusions come into contact they prevent the link chain to rotate farther to that side. Also the links (1) incorporate a vertical step (5) on its inner side by which an inclined vertical side (7) of an adjacent link slides in such a manner that the chain can only be rotated over a predetermined angle defined 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 inclined surface (10) and. a rear inclined surface (11), which are flexible in order to facilitate the assembly of the chain.</p> |
