ABSTRACT:
A lampshade includes first and second annular members, a plurality of spaced-apart flexible supporting rods disposed between the first and second annular members, and a flexible cover sheet body covering the supporting rods. Each supporting rod has first and second ends connected respectively to the first and second annular members. The supporting rods are curved to bulge outwardly to a first position. The first and second annular members are rotatable in opposite directions so as to twist simultaneously the supporting rods to a second position, and are compressible to move toward each other to fold the supporting rods from the second to a third position. The supporting rods are resilient to restore from the third to the first position when the first and second annular members are pulled apart from each other.
