Abstract
Present invention teaches a foldable multi-pane shielding device consisting of a number of connected rigid planar pieces that can be easily deployed when drawn out and set up in a corner of a room or a classroom; a protrusion mechanism in between two connected straight pieces will create a small angle when clicked into place, providing a bow-like tensioning structure and a “pie” safety zone to be formed when the two side pieces are engaged to the walls on the two sides
Claims27
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 means 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.

A shielding device, comprising:
- a. a plurality of rigid planar pieces slidably connected by track formation in a seriatim manner;
- b. wherein said track formation further having a lateral length shorter than the full lateral length of each of said rigid planar pieces;
- c. an inset angled notch on one end of each said rigid planar piece for receiving the other end of an adjacent rigid planar piece;
- and,
- d. a travel limiter means on said track formation, so as to create a small overlapping segment between two adjacent rigid planar pieces with a small angle formed between said two adjacent rigid planar pieces.

A shielding device, comprising:
- a. a plurality of rigid planar pieces slidably connected together by track formations in a seriatim manner;
- b. wherein said rigid planar pieces and the track formations are slightly arc-shaped;
- c. said track formation on each of said rigid planar pieces does not cover the full lateral length of said rigid planar piece;
- and,
- d. said track formations contain travel limiter means, so as to create a small overlapping segment between two adjacent rigid planar pieces.
