It has a base portion that slidingly adjusts along the length of a commercial shelf and supports a vertical blade. The vertical blade may be of different fixed heights, an incrementally adjustable height or a multiple stackable blade array height. The incrementally adjustable height embodiment utilizes a pair of matingly engageable vertical blades that are positioned with respect to each other to achieve the desired height and locked into position with a ratchet locking system. ## Claims ### Claim 1 A vertically, incrementally adjustable one-piece shelf divider having a lowered vertical configuration and a variable raised vertical configuration, comprising: a lower blade base assembly having a slideable, adjustable horizontal shelf bracket and a lower blade which extends perpendicularly from a rear edge of a top face of said horizontal shelf bracket; and an, upper blade that is slidably constrained to said lower blade so as to make a one-piece shelf divider, and is incrementally vertically adjustable above a top edge of said lower blade; wherein said lower blade is vertically corrugated, having a first alternating series of vertical ridges and grooves formed there across; and wherein said upper blade has a second alternating series of vertical ridges and grooves formed there across; and wherein said first and said second alternating series of vertical ridges and grooves make said upper blade and said lower blade matingly engageable; wherein said upper blade and said lower blade reside adjacent and parallel to each other when said shelf divider is in the lowered configuration. ### Claim 2 (depends on 1) The vertically, incrementally adjustable one-piece shelf divider of claim 1 wherein said lower blade and said upper blade each have-an array of open cells formed therethrough. ### Claim 3 (depends on 2) The vertically, incrementally adjustable one-piece shelf divider of claim 2 wherein said horizontal shelf bracket is a C shaped bracket that has a top face that is adapted to span across the top of a shelf, two side arms that extend perpendicularly from a pair of opposing edges of said top face and are adapted to extend across a pair of shelf sides, and a pair of return flanges that extend perpendicularly from a bottom edge of said side arms so as to be adapted to extend partially along a bottom face of said shelf, such that said lower blade base assembly is adapted to wrap partially around a matingly conformed shelf, and is adapted to hold said lower blade perpendicular to said top surface of said shelf. ### Claim 4 (depends on 1) The vertically, incrementally adjustable one-piece shelf divider of claim 1 further comprising: a linear series of vertical ratchet slots disposed along a vertical centerline of said lower blade; and a bendable ratchet tooth having a linear, planar strip body attached at a top end to said upper blade, having a bottom end free to flex horizontally so as to allow a tab extending from a front face, adjacent said bottom end, to engage said ratchet slots to lock a vertical position of said upper blade relative to said lower blade; and a tab at said bottom end of said ratchet tooth angled from a vertical plane of said ratchet tooth body to allow for a tactile ratchet disengagement manipulation. ### Claim 5 (depends on 4) The vertically, incrementally adjustable one-piece shelf divider of claim 4 further comprising: a pair of vertical retention grooves formed continuously along a left vertical edge and a right vertical edge of said lower blade; and a pair of vertical slide edges on a right vertical edge and a left vertical edge of said upper blade, said slide edges having a thickness that is dimensioned for insertion and sliding movement within said vertical retention grooves. ### Claim 6 (depends on 4) The vertically, incrementally adjustable one-piece shelf divider of claim 4 further comprising: a pair of parallel vertical slots formed in said lower blade between a bottom edge to a height below a top edge of said lower blade; and at least one T shaped tab extending perpendicularly from a front face of said upper blade; and wherein said T shaped tab is slidingly engageable within said vertical slot but retains said lower blade and said upper blade in a parallel corrugated configuration.
