Portable shielding device
View Patent ↗Present invention teaches a foldable multi-pan 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.
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.
2. The shielding device of claim 1 , wherein the slidable connection is made at the top or bottom of said rigid planar pieces.
3. 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, hooking mechanisms on the left-most and right-most rigid planar pieces.
4. 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; and foot pieces that have detachable wheels, so as to facilitate moving around on the ground either in the fold-up state or deployed state.
5. 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 plurality of rigid planar pieces are formed by a rigid frame with at least one layer of sturdy flexible fabric-like material fixed to said rigid frame.
