Abstract
A window cover apparatus that includes a window cover substrate and a mechanism for adjusting the configuration of the substrate relative to a window. Illuminating material such as phosphorescent or luminescent material is provided on or in the substrate to provide illumination in darkness. The illuminating material may contain color pigment and be configured to provide a colorful design in both daylight and darkness.
Claims21
An illuminating window covering, comprising:
- a window covering substrate having an interior and an exterior surface;
- a substantially rigid base member to which said substrate is coupled, said base member adapted for mounting to a window frame;
- a mechanism that facilitates extension of said substrate from said base member and retraction of said substrate towards said base member;
- phosphorescent/luminescent (P/L) material applied to a portion of the interior surface of said substrate;
- and
- said substrate is configured at least in part to permit light impinging on said exterior surface of said substrate to pass through said substrate to charge the P/L material on the interior surface of said substrate such that the P/L material emits light visible to a human eye looking at the interior surface of the substrate.

An illuminating window covering, comprising:
- a window covering substrate having an interior and an exterior surface;
- a substantially rigid base member to which said substrate is coupled, said base member adapted for mounting to a window frame;
- a mechanism that facilitates adjustment of the position of the substrate relative to said base member;
- phosphorescent/luminescent (P/L) material coupled to a portion, less than all, of the interior surface of said substrate;
- and said substrate is configured at least in part to permit light impinging on said exterior surface of said substrate to pass through said substrate to charge the P/L material on the interior surface of said substrate such that the P/L material emits light visible to a human eye looking at the interior surface of the substrate.

An adjustable illuminating window covering, comprising:
- a window covering substrate having an interior and an exterior surface;
- a substantially rigid base member to which said substrate is coupled, said base member adapted for mounting to a window frame;
- a mechanism that facilitates adjustment of the position of said substrate relative to said base member;
- illuminating material applied to said substrate that functions as a light source after exposure to incident light;
- and
- said substrate is configured at least in part to permit light impinging on said exterior surface of said substrate to pass through said substrate to charge the illuminating material on the interior surface of said substrate such that the P/L material emits light visible to a human eye looking at the interior surface of the substrate.
