Abstract

An apparatus 10 for shielding a personal occupancy space 11 from electromagnetic and geopathic fields has a floor shield 15 and two side wall shields 18 and 20. The shields are made of ferrous, wire mesh screening and are erected so as to traverse all three spatial protected space. The shields are grounded with the use of a wall plug 29 that has two non-conductive prongs 32 and a conductive grounding prong.

Claims

1. Apparatus for shielding a personal occupancy space such as a sleeping space or working space from ambient electromagnetic and magnetic energy which comprises ferrous screening sized to cover the bottom and two adjacent sides of the space, and grounding means for grounding said ferrous screening, said grounding means includes a wall plug having a plurality of plugs with one plug being electrically conductive and the other plug being electrically non-conductive.

2. The apparatus of claim 1 wherein said screening is comprised of wire mesh screening material.

3. The apparatus of claim 2 wherein said wire mesh screening material has interstices of sizes less than 2.5 centimeters across.

4. The apparatus of claim 1 wherein said screening material comprises galvanized steel.

5. Apparatus for shielding a personal occupancy space from ambient electromagnetic and magnetic fields comprising, in combination, an electrically conductive floor shield sized to underlie a substantial portion of the occupancy space supported along a bottom boundary of the occupancy space, a first electrically conductive side shield mounted uprightly to one side of the occupancy space sized to cover a substantial portion of a side boundary of the occupancy space, a second electrically conductive side shield mounted uprightly to another side of the occupancy space adjacent to the one side sized to cover a substantial portion of another side boundary of the occupancy space, each of said shields being spaced apart from each other, and electrical grounding means grounding said floor shield and grounding said first and second side shields.

6. The apparatus of claim 5 wherein said shields are comprised of wire mesh screening.

7. The apparatus of claim 6 wherein said wire mesh screening has interstices of sizes less than 2.5 centimeters across.

8. The apparatus of claim 5 wherein said shields are comprised of galvanized steel.

9. The apparatus of claim 8 wherein said shields are further comprised of a metal selected from the group consisting of copper and aluminum.

10. The apparatus of claim 5 wherein said grounding means comprises conductors electrically connecting together said floor shield and said first and second side shields.

11. The apparatus of claim 5 wherein each of said shields is substantially flat.

12. Apparatus for shielding a personal occupancy space from ambient electromagnetic and magnetic fields comprising, in combination, an electrically conductive floor shield sized to underlie a substantial portion of the occupancy space supported along a bottom boundary of the occupancy space, a first electrically conductive side shield mounted uprightly to one side of the occupancy space sized to cover a substantial portion of a side boundary of the occupancy space, a second electrically conductive side shield mounted uprightly to another side of the occupancy space adjacent to the one side sized to cover a substantial portion of another side boundary of the occupancy space, and electrical grounding means grounding said floor shield and grounding said first and second side shields, said grounding means comprises a three prong plug with one of said prongs being electrically conductive and two others of said prongs being electrically non-conductive.
