ABSTRACT:
A double sunshade includes a main shank, a left subordinate sunshade, a right subordinate sunshade and a canopy. The main shank has a main cap atop and a main runner fitted movably around the main shank, main spreaders pivotally connected to the main runner, and main ribs pviotally connected to the main inside cap. The main ribs cross with the main spreaders at pivotal points and then extends further outward to be pivotally connected to subordinate inside caps and subordinate runners of the left and the right subordinate sunshades. Then the subordinate runners of the left and the right subordinate sunshades may be moved up and down for spreading or collapsing the subordinate spreaders and the subordinate ribs when the main runner is moved up and down, with a canopy spread or collapsed, too. And the canopy has a zipper or a Velcro band sewn at its peripheral edge for connecting a double sunshade to another for enlarging the dimensions for shading.
