发明名称 Changeable sign board with magnetic characters
摘要 A changeable sign includes a flat magnetizable sheet metal sign board, and a plurality of trapezoidal segments of magnetic sheet material sized and arranged to form segmented alphanumeric characters magnetically adhered to the board. The board also includes space to apply a sheet of magnetic material containing printed information. Semi-invisible guidelines on the board, such as glossy lines on a flat background of the same color, guide the positioning of the segments to form the characters. The segments are formed with non-acute angle corners to maximize adherence at their corners. The segments are rearranged to form different characters and can be repositioned at will on the sign board over the guidelines to completely alter the sign format.
