Abstract:
A map or chart with an upper edge, lower edge, left edge, right edge, a front surface display area of four panels of contiguous topographical or diagrammatic features, multiple leaves rooted between the vertical edge panels for accessing all other display locations, a cover to make permanent and stabile the leafing format and for folding for storage, said map comprising:A. three horizontal evenly spaced folds that form four panels, the first from the top an inward fold, the second an outward fold at the centerline, and the third an inward fold, and an odd-number of vertical folds of three or more, alternately folded inwardly and outwardly to form double leaves between the single-leafed left and right edge panels, the resultant folds causing an even number of multiple panels, andB. a slit along the horizontal centerline's outer fold line between the inner edges of the left and right edge panels which slit enables the map to be divided into a top and bottom section with leaves that can turn independently of each other, andC. from the map's unfolded open position, fanfolded the vertical outer folds into leaves, overlayed them onto the left edge panels with the right edge panels remaining open, abutted the left and right edge panels, resulting in a two-panel wide strip of the right side panels, andD. an outward final fold at the horizontal centerline fold to form a horizontal leaf, to adjoin the inner edges of the four corner panels, to overlay the leaf upon the bottom panels, to position all leaves between the side panels along the vertical centerline, resulting in the base configuration for the map paging format and a display page of the top section's right-most four panels.
