TRIANGULAR PYRAMID TYPE CUBIC CORNER RETROREFLECTION ARTICLE, AND ITS MANUFACTURING METHOD |
摘要 |
<p>The present invention relates to a triangular pyramidal cube corner retroreflective article and a producing method, thereof. In the triangular pyramidal cube corner retroreflective article, a triangular pyramidal cube corner retroreflective element pair group is disposed in a closest-packed fashion on a common plane defined by three base lines, and the each of retroreflective elements in a pair having one base line (A-B) shared by the retroreflective elements in the pair. The triangular pyramidal cube corner retroreflective article includes a first element pair group, in which two interior angles (±=ˆ EAC and ²=ˆ ABC) formed by the shared base line of the element pair and two other base lines are different from each other and the element pair is line-symmetrically disposed in relation to the shared base line (A-B); and a second element pair group, in which the element pair is congruent to a line-symmetrical shape to the first element pair in relation to a line segment connecting vertexes of the base planes.</p> |
