Abstract:
1. A magnetically actuated visual display board device for using magnetic attraction to form and erase visual images, the device comprising: a visual display board comprising a grid array of chambers, each of the chambers having an opening on at least one face of the display board; an elongated magnetic rod having a least one magnetic end smaller than the opening in each of the chambers, the magnetic rod moved by a user in front of the array of chambers; at least one loop of planar display material within each of the chambers adjacent to the opening, the at least one loop of display material comprising two adjacent visual display surfaces connected together by means for allowing a first visual display surface to pivot relative to a second visual display surface, the visual display surfaces each having a display face visually distinct from the display face of the other visual display surface, the display faces alternate visible through the opening; the second visual display surface attached to a first inside wall of the chamber by means for allowing the second visual display surface to pivot relative to the first inside wall of the chamber, the second visual display surface normally in a first position perpendicular to the first inside wall and visible through the opening in each of the chambers; a sliding member inside the chamber attached to the first visual display surface by means for allowing the first visual display surface to pivot relative to the sliding member, the sliding member being movable within the chamber to move toward and away from the opening along a second interior wall of the chamber parallel to and spaced apart from the first interior wall, the sliding member normally positioned away from the opening so that the first visual display surface is parallel to and adjacent to the second interior wall
