Abstract

A mirror comprises a myriad of reflecting surfaces so aligned as to produce a virtual image which may be plain or focused. The surfaces may be irregular in outline to minimize or prevent glint patterns.

Claims

1. In a mirror, the combination comprising:

(a) a support,

(b) a myriad of surfaces carried by the support, certain of said surfaces dimensionally offset from one another in a common direction generally parallel to the general direction of incident radiation to be reflected, said surfaces being radiation reflecting surfaces each oriented in such a way that as a group they collectively reflect radiation essentially as if they were a continuous reflecting surface,

(c) each of said surfaces having a periphery comprising an irregular series of line segments which are connected and curved, the peripheries of said surfaces, when projected in said common offset direction onto a plane perpendicular thereto, contiguously conforming to one another.

2. The combination of claim 1 wherein the support has curvature and/or orientation which differs from the curvature and/or orientation of the continuous reflectng surface referred to in claim 1.

3. The combination of claim 1 wherein a second group of surfaces, are transparent, and are interspersed among the surfaces of the first group.

4. The combination of claim 1 wherein said support consists of molded plastic material.

5. The combination of claim 2 wherein said support consists of molded plastic material.

6. The combination of claim 3 wherein said support consists of molded plastic material.

7. The combination of claim 4 including a dimensionally stable carrier on which said support is carried.

8. The combination of claim 7 wherein said carrier consists of glass.

9. The combination of claim 7 wherein said support and said carrier are light transparent, and radiation reflects from said reflecting surfaces after penetrating the said carrier and said support.

10. The combination of claim 7 wherein said reflecting surfaces are at the side of the support furthest from the carrier.

11. The combination of claim 1 including a second group of said surfaces and wherein radiation reflecting surfaces from more than one of said groups are associated in the same holder in such a manner that each group of surfaces collectively acts as a continuous reflecting surface, and wherein each group represents a continuous reflecting surface which differs in continuity from that of any other adjacent group of surfaces.

12. The combination of claim 11 wherein two or more groups of surfaces occupy different but adjacent areas.

13. The combination of claim 11 wherein the radiation reflecting surfaces defined by different groups are interspersed relative to the support.

14. The combination of claim 11 wherein surfaces in one or more groups are non-reflecting.

15. The combination of claim 14 wherein the surfaces of one or more groups of non-reflecting surfaces are made transparent.

16. The mirror of claim 1 in which, for diminishing the intensity of the reflection at night, metalizing material is placed on a hinged and movable negative casting of the reflecting surfaces, and characterized in that the metalized material may be adjusted to fit snuggly for maximum reflectance, and may be swung away affording a less-intense reflection from the non-metalized surfaces.

17. The mirror of claim 1 in which, for diminishing the intensity of the reflection at night, metalized material is placed on the surface of a compliant, non-rigid plastic pad which, when forced with adjustable degrees of pressure against the back of the reflecting surfaces, will cause the pad to comply with each surface, thereby increasing or decreasing reflectance for each sector of the mirror.

18. The mirror of claim 1 wherein one group of said surfaces is contained in one part of the area of a rear view mirror, and another group or groups of such surfaces is or are contained in another adjacent part or parts of a rear view mirror, said adjacent parts of the rear view mirror being contiguous.

19. The mirror of claim 18 wherein a juncture zone is formed between said adjacent parts, said juncture zone including a mixture of contiguous surfaces from the adjacent groups of surfaces.

20. The mirror of claim 19 wherein in the juncture zone the relative population densities of surfaces from the two adjacent groups of surfaces varies across the juncture zone.

23. The combination of claim 17 wherein two or more groups of said surfaces are combined in two or more areas of a thereby defined rear view mirror for use in association with a vehicle, whereby the viewer may view objects at the rear flanks of the vehicle as well as at the rear of the vehicle.

26. The combination of claim 16 wherein there is also a third group of radiation reflecting surfaces associated with said first and second groups of surfaces, all of said surfaces combined in one mirror for use in an automobile, one of said groups of surfaces being centrally located relative to the other two groups of surfaces which are in mirror areas respectively at the left and right of said one group, and wherein the centrally located group of radiation reflecting surfaces represents a planar mirror for the automobile driver to view an undistorted reflection out the rear window of the automobile, and the radiation reflecting surfaces at said left and right mirror areas represent convex mirrors oriented to afford to the driver condensed views of objects at the left and right flanks of the automobile, respectively.

21. In a mirror, the combination comprising:

(a) a support, and

(b) a myriad of surfaces carried by the support, certain of said surfaces dimensionally offset from one another in a common direction generally parallel to the average direction of incident light to be reflected, there being one group of surfaces representing one continuous reflecting surface, and there being a second group of reflecting surfaces representing another continuous reflecting surface, and said individual surfaces from both groups of surfaces being contiguously interspersed to cover the entire area of the mirror.

22. The combination of claim 21 wherein surfaces of the second group are reflecting surfaces and face directionally differently from the surfaces of the first group so that radiation from two different areas is reflected toward an observer by the first and second group surfaces, respectively.

24. The combination of claim 21 wherein surfaces of the second group are non-reflecting.

25. The combination of claim 24 wherein the second group surfaces are located on transparent extents of the support.
