US 2011/0255164 A1 · VEHICLE REFLECTOR AND REFLEX PIN

Abstract

A vehicle reflector can include a plurality of retroreflection elements including a first reflection surface, a second reflection surface, and a third reflection surface which are adjacently disposed to form a corner portion of a substantially regular hexahedron. The first reflection surface can be inclined by 35.264°+angle α1 with respect to a reference axis. The second reflection surface can be inclined by 35.264°+angle α2 with respect to the reference axis and can be disposed at a position rotated by 120° about the reference axis from the first reflection surface. The third reflection surface can be inclined by 35.264°+angle α3 with respect to the reference axis and can be disposed at a position rotated by 120° in an opposite direction from the second reflection surface about the reference axis from the first reflection surface. The angle α1, angle α2 and angle α3 can be set to satisfy a relation of −α1=α2=α3 or −α1≈α2=α3.

the first reflection surface is inclined by 35.264°+angle α1 with respect to a reference axis,
the second reflection surface is inclined by 35.264°+angle α2 with respect to the reference axis and is disposed at a position rotated by 120° about the reference axis from the first reflection surface,
the third reflection surface is inclined by 35.264°+angle α3 with respect to the reference axis and is disposed at a position rotated by 120° in an opposite direction from the second reflection surface about the reference axis from the first reflection surface, and
