A structure with extensible/retractable panels, which provides variable surface area for items such as headgear brims, furniture tops, etc., includes a first panel, a second panel pivotally mounted to the first panel, and a third panel pivotally mounted to the first panel. The second and third panels are rotatable from a retracted position in which the second and third panels are positioned underneath the first panel, and a deployed position in which the second and third panels extend beyond both the length and width of the first panel. |
