Visible index system with improved hanger

A visible index system which comprises:

• a plurality of pocket cards, each having hinges at opposite ends of one edge thereof;
• a pocket card support having inwardly opening recesses extending along the opposite sides thereof;
• and wire hangers for detachably affixing said pocket cards to said pocket card support, said wire hangers being associated with said pocket cards on a one-to-one basis and each wire hanger having:
• a substantially rectilinear main body portion extending along said one edge of the associated pocket card and an integral loop portion at each end of said main body portion, said loop portions being installed in the inwardly directed recesses at the opposite sides of said pocket card support to thereby detachably secure said hanger to said support and each said loop portion having a pair of spaced, substantially parallel sides with longitudinal axes which:
• lie in the same plane as the longitudinal axis of said main body portion, extend substantially parallel to the longitudinal axis of said main body portion, and are symmetrically disposed on opposite sides of said longitudinal axis of said main body portion, one of said sides of each said loop portion having a free end portion which extends along and substantially parallel to said longitudinal axis of said main body portion and lies to one side of said main body portion, the longitudinal axes of the main body portion and the free end portions of said hanger being contained in a plane disposed at a right angle to the plane containing the longitudinal axes of said main body portion and the parallel sides of said loop portions, and said free portions of the hanger extending through said hinges to thereby pivotably secure said associated pocket card to said hanger.
