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, and

(b) a myriad of irregularly outlined surfaces carried by the support, certain of said surfaces dimensionally offset from one another in a common direction generally parallel to the incident radiation to be reflected, said surfaces being discrete radiation reflecting surfaces each oriented in such a way that as a group they collectively reflect images of objects toward a viewer'"'"'s eye location and essentially as if they were a continuous reflecting mirror surfaces, said irregularly outlined surfaces defining successive planes across the mirror surface, and which are progressively increasingly angled relative to a flat plane extending generally parallel to the mirror surface.

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 reflecting surface referred to in claim 1.

3. The combination of claim 1 wherein a second group of said surfaces, with the same outlines as those in the first group are transparent for passing incident radiation, 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 at least 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 manner that they collectively act as a substantially continuous reflecting surface.

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 having a generally V-shaped profile.

22. The combination of claim 1 wherein said first group surfaces are angled to reflect light to a viewer'"'"'s eye zone.

17. 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 direction of incident radiation to be reflected, a first group of said surfaces being radiation reflecting surfaces, there being a second group of said radiation reflecting surfaces, the surfaces of the first and second groups being interspersed, the surfaces of each group defining successive planes across the mirror surface associated with the group, said planes being progressively increasingly angled relative to a flat plane extending generally parallel to the mirror surface associated with that group.

18. The combination of claim 17 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.

19. The combination of claim 18 wherein said surfaces and support define a rear-view mirror for use in association with a vehicle, whereby the viewer may view objects at the side as well as at the rear of the vehicle.

20. The combination of claim 17 wherein surfaces of the second group are non-reflecting.

21. The combination of claim 20 wherein the second group surfaces are located on transparent extents of the support.

23. A vehicle rear view mirror which comprises:

(a) one section with multiple discrete reflecting surfaces with a common orientation to reflect images of objects at the rear of the vehicle toward a viewer'"'"'s eye location, and other sections with discrete reflecting surfaces oriented to reflect images of objects at the rear flanks of the vehicle toward the viewer'"'"'s eye location,

(b) there being a mirror transition zone between said sections characterized by discrete reflecting surfaces certain of which reflect said images of objects at the rear of the vehicle toward the viewer'"'"'s eye location, and others of which reflect said image of objects at the rear flanks of the vehicle toward the viewer'"'"'s eye location.

24. The mirror of claim 23 wherein said certain and other surfaces are interspersed.

25. The mirror of claim 24 wherein the areal density of said certain surfaces diminished in a direction from said one section toward said other section, over the transition zone, and the areal density of said other surfaces diminished in a direction from said other section toward said one section, over the transition zone.

26. The mirror of claim 23 having a support with a flat side adhered to the side of a glass plate furthest from the driver, such that said reflecting surfaces are still further from the driver.

27. The mirror of claim 26 having a V-shaped profile, with an apex directed generally toward the driver.

28. The mirror of claim 23 wherein the reflecting surfaces of said other sections define generally convex section surfaces.
