Aperture cover for blocking electromagnetic radiation
First Claim
Patent Images
1. At least one covering for an aperture for regulating light, comprising:
- electromagnetic shielding material comprising at least two electrically conductive layers with different shielding properties;
said material defining at least one generally planar surface;
additional shielding material on the periphery of the covering that fills a gap between the covering extending generally orthogonally away from said at least one generally planar surface and the aperture when the covering is in use, where the additional shielding material is electrically connected with the electromagnetic shielding material.

Abstract
An aperture covering, such as a window shade, comprises a shade body (10), a shielding member (24) provided on a shade-body periphery facing a window frame (2), and a shade-body winding mechanism (6). The shielding member (24) is conductive and contacts the window frame (2) to close the space between the shade body (10) and the window frame (2). When the winding mechanism (6) winds the shade body (10) down to cover the window frame (2) with the shade body (10), the window shade blocks electromagnetic energy inside and outside a building, while regulating light entering the building through a window.

8. A window shade for regulating light entering through a window by raising and lowering a shade body, comprising:
-
an electromagnetic shielding material, comprising at least two electrically conductive layers with different shielding properties; said material defining at least one generally planar surface; a strip of shielding material on the periphery of the shade body, which extends generally orthogonally away from said at least one generally planar surface which periphery faces a window frame, where the strip of shielding material closes a clearance between the window frame and the shade body, when in use the strip of shielding material being electrically connected with the electromagnetic shielding material. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
