Abstract

In a preferred embodiment of the present invention, the sign includes a plurality of spaced cutouts that either cut out at least a portion on or near the edge of at least one alphanumeric character or symbol in the indicia or are disposed within at least one alphanumeric character or symbol in the indicia, the cutouts being disposed with gaps therebetween and configured such that the corresponding at least one alphanumeric character or symbol is more legible when viewed in bright sunlight, esp. in situations of sun blindness.

Claims

1. An outdoor sign with improved legibility in bright sunlight of indicia printed thereupon, the sign comprising:

a plurality of spaced cutouts that either cut out at least a portion on or near the edge of at least one alphanumeric character or symbol in the indicia or are disposed within at least one alphanumeric character or symbol in the indicia, said cutouts being disposed with gaps therebetween and configured such that the corresponding at least one alphanumeric character or symbol is more legible when viewed in bright sunlight.

2. The outdoor sign of claim 1, wherein at least a portion of said cutouts are disposed just outside and along an edge of at least one alphanumeric character or symbol in the indicia.

3. The outdoor sign of claim 1, wherein at least a portion of said cutouts are disposed upon an edge of at least one alphanumeric character or symbol in the indicia.

4. The outdoor sign of claim 1, wherein at least a portion of said gaps are minimal sized between adjacent cutouts to maintain structural integrity of said sign under intended operating conditions.

5. The outdoor sign of claim 1, wherein at least a portion of said cutouts have and alternating pattern of adjacent cutout shapes to maintain structural integrity of said sign under intended operating conditions.

6. The outdoor sign of claim 1, wherein said sign is not electrically powered to make it more legible when viewed in bright sunlight.

7. The outdoor sign of claim 1, wherein at least a portion of said cutouts are disposed midway between opposing edges of at least one alphanumeric character or symbol in the indicia, thereby forming a central lined representation of the corresponding alphanumeric character(s) or symbol(s) in the indicia.

8. The outdoor sign of claim 1, wherein at least a portion of said cutouts are configured to be shaped as a cutout circle, elongated rectangle, or other geometric shape.

9. The outdoor sign of claim 1, wherein at least a portion of said cutouts are configured to be sized large enough to allow enough sunlight to pass through them to provide adequate visual distinction between the cutout regions and the non-cutout regions to thereby improve the legibility of the corresponding alphanumeric character(s) or symbol(s) in the indicia.

10. The outdoor sign of claim 1, wherein at least a portion of said cutouts are configured to be sized wider in the back of said sign than the corresponding locations on the front of said sign, the size difference being suitable for collecting more light from light from the backside and funneling the increased collected light to the front side.

11. The outdoor sign of claim 1, wherein at least a portion of said cutouts are configured to be filled with a translucent material that alters sunlight to provide adequate visual distinction between the filled cutout regions and the non-cutout regions to thereby improve the legibility of the corresponding alphanumeric character(s) or symbol(s) in the indicia.

12. The outdoor sign of claim 1, wherein said sign requires no ongoing maintenance to make it more legible when viewed in bright sunlight.

13. The outdoor sign of claim 1, wherein at least a portion of said cutouts are configured to allow wind to pass through them under windy conditions to reduce the overall force imparted to said sign by wind.

14. An outdoor sign with improved legibility in bright sunlight, the sign comprising:

indicia printed upon said sign, the indicia having at least one alphanumeric character or symbol; and

means for making at least one alphanumeric character or symbol in said indicia more legible when viewed in bright sunlight.

15. The outdoor sign of claim 14, in which said means for improved indicia legibility further comprises means for maintaining structural integrity of said sign under intended operating conditions.

16. The outdoor sign of claim 14, in which said means for improved indicia legibility further comprises means for collecting more light from light from the backside and funneling the increased collected light to the front side.

17. The outdoor sign of claim 14, in which said means for improved indicia legibility further comprises means for reducing the overall force imparted to said sign by wind under windy conditions.

18. A method for making an outdoor sign with improved legibility in bright sunlight of indicia printed thereupon, the method comprising:

steps for making at least one alphanumeric character or symbol in said indicia more legible when viewed in bright sunlight.

19. The method of claim 18, further comprising Steps for maintaining structural integrity of said sign under intended operating conditions.

20. The method of claim 18, further comprising Steps for noticeably reducing the overall force imparted to said sign by wind under windy conditions.
