Abstract: A folding car rack having first and second rigid side members each of which has first and second ends. The roof rack also includes first and second rigid end members, each of which has first and second ends. A first articulated joint connects the first end of the first side member to the first end of the first end member. A second articulated joint connects the first end of the second side member to the first end of the second end member. A first separable connector temporarily joins the second end of the second end member to the second end of the first side member when the roof rack is being used. A second separable connector temporarily joins the second end of the first end member to the second end of the second side member when the roof rack is being used. A plurality of cargo support members having ends which are articulated to the first and second side members are also articulated approximately midway between their ends.
