ABSTRACT:
This invention is a new designed configuration of a laminated folding navigation chart. This said chart is intended for pilots and navigators of small planes and watercraft. This said navigation chart consists of a plurality of (preferably 10) panels that are flexibly coupled together at their contiguous edges. The said transparent flexible couplings herein described allow epicycle multiplicity folding of said panels relative to each other. This said epicycle multiplicity folding of panels allows the chart to be viewed clearly while in the fully open position, partial open position or in a single panel closed position.
