Abstract:
1. A shielding device, comprising: a. a plurality of rigid planar pieces slidably connected together in a seriatim manner; b. a pop-out ball structure and a corresponding receiving cavity on two adjacent said rigid planar pieces respectively, so that when two adjacent rigid planar pieces are moved laterally to form a drawn out extended screen shape, said ball structure on one rigid planar piece will click into the corresponding receiving cavity on the adjacent rigid planar piece to stop further lateral movement, having a small overlapping segment between two adjacent rigid planar pieces; and, c. a protrusion actuated by the clicking-in of said pop-out ball structure to the corresponding receiving cavity, resulting in the intended protrusion from one rigid planar piece to push away the adjacent rigid planar piece and creating a small angle between the two adjacent rigid planar pieces, wherein said protrusion is a pivoting rod.
