Stair step portfolio file

摘要

A stair-step, expandable file folder is disclosed, in which each pocket in the folder has the same depth, rather than the back pockets being deeper than the front pockets. The folder includes a series of dividers that form the front and back sides of the pockets of the folder. The top edges of the dividers have increasing height, from the front to the back of the folder. The dividers are folded to form the bottoms of the pockets, with the folded portions also increasing in height from the front to the back of the folder. Each divider extends downward to form the back face of a pocket, is folded forward to form the bottom face of the pocket, and is folded downward to extend toward the bottom edge of the folder. The troughs in an expandable gusset support the sides of the dividers. Above the fold portion, the divider laterally extends into one trough. Below the fold portion, the divider laterally extends into the adjacent trough toward the front of the folder.

主权项

1. A stair-step file folder having a plurality of top-accessible pockets, comprising:
a plurality of dividers defining the pockets therebetween; a web formed to provide a bottom and two sidewalls of the folder; a plurality of dividers of uniform height between and having a front back face, said dividers being affixed to said web at the sidewalls thereof; said dividers being formed of a single folded web having an upper generally planar portion lying with in a first plane, a fold portion, constituting a floor, that extends generally orthogonally from said plane and away from the upper planar portion and a lower generally planar portion extending generally orthogonally from said fold portion and residing in a second plane parallel to and offset from said first plane; the plurality of dividers being spaced apart generally equal to an offset created by the fold portion; the plurality of dividers being joined such that each floor is bounded by planar portions of successive dividers; the location of the fold portion on each divider being successively higher from front to back, so that the floor of each pocket is likewise successively higher; and each divider being formed of a continuous web material and wherein each divider has the lower planar portion extending downwardly below the fold portion.
