<p>1. Awning comprising, on the one hand, a rotary roller, a loading bar and a web which is rolled on the roller and which is fixed by its free edge to the loading bar, and on the other hand, supports (3 and 4) and struts, the arms (1 and 2) of which, being articulated together, are movable in a single virtual plane and are, moreover, each articulated by one of their end to a support (3-4) and by the other of their ends to the single loading bar, the various articulation pivots of the struts all having an axis perpendicular to the plane of the struts, while the supports (3 and 4) are integral with a bar (5) parallel to the loading bar, characterised in that this bar (5) is pivotably mounted in bearings (6 and 7) which are fixed below the roller and which are of the type involving permanent friction, of which the value, preferably adjustable, is set below a blocking value, in order that it is possible, without action on the bearings, for the awning to be pivotally displaced.</p> |
