Abstract
Abstract A reflector such as may be used in the creation of road signs and warning signals and the like comprises the formation of a myraid of rhombic parallelograms each of which in turn has a raised surface consisting of a plurality of flat facets arranged at desirable angles with respect to one another. Three of the faceted rhombic parallelograms are grouped about a common center so as to form a six-sided hexagon. A plurality of such hexagons sufficient to cover a desired area results in a reflector of unusual light reflective capabilities.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
209 words
A reflector comprising a base means, a plurality of side-byside, juxtaposed rhombic reflector units on said base means and each having opposite side edges, opposite end edges and a plurality of flat, differently angularly disposed light reflective surfaces outwardly inclined from the plane of said base means, said reflective surfaces defined at least in part by a diagonal center ridge line extending between opposite corners of each rhombic reflector but spaced at its opposite ends from said opposite corners, and a pair of peak lines extending laterally in opposite directions from each of the opposite ends of said ridge line to adjacent sides of the reflector unit, thus defining two adjacent, different size pentagonal reflective surfaces on opposite sides of said ridge line and two trapezoidal reflective surfaces at opposite ends of said ridge line and between said pairs of peak lines, said reflector units arranged in groups of three with two adjacent sides of each of said three reflector units contiguous with an adjacent side of each of the other two of said three reflector units, thus defining a hexagonally shaped array of said three reflector units, and other said reflector units similarly arranged in regularly repeating, hexagonally shaped arrays adjacent said array of said three reflector units.
Claim 2
Dependent Claim
209 words
A reflector comprising a base means, a plurality of side-byside, juxtaposed rhombic reflector units on said base means and each having opposite side edges, opposite end edges and a plurality of flat, differently angularly disposed light reflective surfaces outwardly inclined from the plane of said base means, said reflective surfaces defined at least in part by a diagonal center ridge line extending between opposite corners of each rhombic reflector but spaced at its opposite ends from said opposite corners, and a pair of peak lines extending laterally in opposite directions from each of the opposite ends of said ridge line to adjacent sides of the reflector unit, thus defining two adjacent, different size pentagonal reflective surfaces on opposite sides of said ridge line and two trapezoidal reflective surfaces at opposite ends of said ridge line and between said pairs of peak lines, said reflector units arranged in groups of three with two adjacent sides of each of said three reflector units contiguous with an adjacent side of each of the other two of said three reflector units, thus defining a hexagonally shaped array of said three reflector units, and other said reflector units similarly arranged in regularly repeating, hexagonally shaped arrays adjacent said array of said three reflector units.
Claim 3
Dependent Claim
39 words
A reflector as in claim 1, wherein the different size pentagonal reflective surfaces and the trapezoidal reflective surfaces are contiguous with like reflective surfaces on adjacent reflector units, thus defining three different shaped major reflective areas on said reflector.
Claim 4
Dependent Claim
30 words
A reflector as in claim 1, wherein the pentagonal reflective surfaces are larger than the trapezoidal reflective surfaces, and said trapezoidal reflective surfaces are equal in size to one another.
Claim 5
Dependent Claim
24 words
A reflector as in claim 1, wherein the pentagonal reflective surfaces are disposed at an angle of about seventy degrees relative to one another.
Claim 6
Dependent Claim
33 words
A reflector as in claim 1, wherein one of the peak lines at each end of the ridge line extends outwardly at an angle of about thirty degrees relative to the ridge line.
Claim 7
Dependent Claim
33 words
A reflector as in claim 5, wherein the other of said peak lines at each end of the ridge line extends at an angle of about sixty degrees relative to the ridge line.
Claim 8
Dependent Claim
34 words
A reflector as in claim 2, wherein each of said reflector units in each hexagonal array forms with two adjacent reflector units of adjacent hexagonal arrays a further hexagonal array of three reflector units.
