Reflective material for signage, buildings and vehicles
First Claim
1. A reflective sheet material for signage, vehicle surfaces, and building surfaces, comprising:
- a sheet member constructed of rigid material and having a series of adjacent parallel primary grooves extending across at least one surface, each primary groove defined by first and second elongate facets forming an angle of at least 90 degrees in a first plane perpendicular to the at least one surface and perpendicular to the lengthwise direction of the facets, said grooves having a depth which is less than the thickness of the sheet member, each first facet having a width extending in said first plane substantially shorter than a corresponding width of said second facet, said first facet extending at an angle ranging between 60 and 80 degrees to a second plane defined by top edges of the groove defined by the respective facets, and said second facet extending at an angle ranging from 10 and 30 degrees to said second plane;
a thin opaque reflective layer extending over and attached to said at least one surface in the region of said series of primary grooves, said reflective layer conforming to said series of primary grooves so as to form a series of associated angular grooves defined by elongate reflective facets; and
a transparent material extending over and substantially filling said associated angular grooves in the reflective layer, wherein said transparent material forms a substantially smooth outer surface of said sheet material located at or close to top edges of said angular grooves,wherein said sheet material is substantially rigid.

Abstract
A reflective sheet material for use on exterior signs and exposed surfaces includes a sheet member having a series of adjacent, parallel primary grooves extending across at least one surface. Each group is defined by first and second elongate facets forming an angle of at least 90 degrees in a plane perpendicular to the surface and to the length of the facets. A thin opaque, reflective layer extends over the surface in the region of the grooves and conforms to the series of grooves so as to form a series of associated angular grooves. A transparent material extends over and substantially fills these angular grooves, thereby forming a substantially smooth outer surface which is located at or close to the top edges of the grooves. The sheet material can be flexible or rigid.
