<p>In collapsible canvas coverings (1) substantially comprising a canvas (1) supported by a plurality of arches (2) mutually connected by pantograph linkages and therefore capable of being mutually brought closer or moved apart in order to uncover or to cover the sheltered area, the pantograph linkages have been improved in order to avoid tearings of the canvas and/or injuries. Each unit of the pantograph linkage comprises, in a way known per se, two rods (7, 7') mutually pivoted in a St. Andrews' cross fashion, in the middle area thereof, wherein said rods have been bent in such a way that each arm (15, 15'), upstream from said middle area is offset both relative to the other arm and relative to the pivot pin (8) connecting both rods together.</p> |
