| 1990 | Invention patented by Alan H. Swing on October 31th, 1990. Abstract: A beach towel or blanket with a metal eyelet on its bottom edge through which a decorative pivot dowel is passed and into the sand at the beach. Said towel is held, by one person, at the corners of the opposite end and rotated about the pivot dowel until the shadow of the pivot dowel is aligned with the shadow line (or center) of the symmetry gauge printed on the beach towel. This positions the beach towel and subsequent sun bather at the most advantageous position to receive the sun's rays for symmetrical tanning for that period of the day. As the day progresses the beach towel will have to be rotated to keep the shadow of the pivot dowel within the symmetry tanning gauge. During this simple, timeless, re-alignment, the sun bather would doubtlessly evaluate their exposure time in the sun which is a health and safety feature in itself. |
