Abstract
A portable shade structure includes a structural framework with space supports, and hook-receiving holes along some of the supports. A removable fabric cover fits across the structural framework, and has plural hooks attached at spaced locations dimensioned to removably fit into the hook-receiving holes of the support. Each hook has a curved return which permits the hook to be engaged within a corresponding hole, but which provides a smooth surface that reduces snagging when the hook is moved across, or is stored against the fabric cover.
