Abstract

The invention is a convex mirror for surveillance purposes, in combination with an advertising message, and the method of fabricating same. A removable mask is attached to the interior of the surface to be mirrored, and a non-reactive removable liquid mask is applied to the openings in the removable mask. The removable mask is removed, and a mirror material is applied to the surface. The liquid mask is allowed to solidify, then removed, leaving one or more transparent areas in the surface of the mirror.

Claims

1. A convex surveillance mirror, comprising:

a transparent base formed as a segment of a hollow sphere and having an outer convex surface, an inner concave surface, a center portion and a substantially circular edge;

a thin reflective coating incompletely covering said inner concave surface so as to leave portions thereof uncovered in a predefined pattern, said predefined pattern located proximate a portion of the edge of said base, leaving said center portion unobstructed;

a light source mounted proximate said inner concave surface; and

a support mechanism attached to said base for mounting said mirror,

wherein light from said light source is transmitted through said predefined pattern to provide a visible contrasting image on the outer surface of said mirror.

2. The invention of claim 1, wherein said predefined pattern comprises a readable printed message.

3. The invention of claim 1, wherein at least one colored plastic insert is disposed between said predefined pattern and said light source.

4. The invention of claim 3, wherein a plurality of differently colored plastic inserts are disposed between said predefined pattern and said light source.

5. The invention of claim 3, wherein said support mechanism comprises a backing plate affixed across the opening created by said inner concave surface and a fastener attached to said backing plate for attachment of said mirror to a surface.

6. A convex surveillance mirror, comprising:

a transparent thermoplastic base formed as a segment of a hollow sphere and having an outer convex surface, an inner concave surface, a center portion, and a substantially circular edge;

a thin reflective coating incompletely covering said inner concave surface so as to leave portions thereof uncovered in a predefined pattern, said predefined pattern located proximate a portion of the edge of said base, leaving said center portion unobstructed;

a backing plate affixed across the opening created by said inner concave surface;

a light source secured to said backing plate and operative to illuminate said inner concave surface; and

a fastener attached to said backing plate for attachment of said mirror to a surface;

wherein light from said light source is transmitted through said predefined pattern to provide a visible contrasting image on the outer surface of said mirror.

7. The invention of claim 6, wherein said predefined pattern comprises a readable printed message.

8. The invention of claim 6, wherein at least one colored plastic insert is disposed between said predetermined pattern and said light source

9. The invention of claim 8, wherein a plurality of differently colored plastic inserts are disposed between said predetermined pattern and said light source.

10. A convex surveillance mirror, comprising:

a transparent base formed as a segment of a hollow sphere and having an outer convex surface and an inner concave surface;

a thin reflective coating incompletely covering said inner concave surface so as to leave portions thereof uncovered in a predefined pattern, said predefined pattern comprising a readable printed message;

a light source mounted proximate said concave inner surface; and

a support mechanism attached to said base for mounting said mirror,

wherein light from said light source is transmitted through said predefined pattern to provide a readable printed message on the outer surface of said mirror.

11. The invention of claim 10, wherein at least one colored plastic insert is disposed between said predefined pattern and said light source.

12. The invention of claim 10, wherein a plurality of differently colored plastic inserts are disposed between said predefined pattern and said light source.

13. A convex surveillance mirror, comprising:

a transparent thermoplastic base formed as a segment of a hollow sphere and having an outer convex surface and an inner concave surface;

a thin reflective coating incompletely covering said inner concave surface so as to leave portions thereof uncovered in a predefined pattern, said predefined pattern comprising a readable printed message;

a backing plate affixed across the opening created by said inner concave surface;

a light source secured to said backing plate and operative to illuminate said inner concave surface; and

a fastener attached to said backing plate for attachment of said mirror to a surface;

wherein light from said light source is transmitted through said predefined pattern to provide a readable printed message on the outer surface of said mirror.

14. The invention of claim 13, wherein at least one colored plastic insert is disposed between said predefined pattern and said light source.

15. The invention of claim 13, wherein a plurality of differently colored plastic inserts are disposed between said predefined pattern and said light source.
