Patent ID: 8695320

Claim:
A non-back-bending chain comprising: a plurality of links pivotably connected to each other; a tab included in each of said links; a tab recess included in each of said links so that when links are adjacent and in an interlocked position, said tab of the adjacent link is received in the tab recess and when said links are rotated away from an interlocked position, the tab is removed from said tab recess allowing the chain to bend; a plurality of pins pivotably connecting said links so that said chain will bend in a direction toward a top edge, but will not bend past a predetermined point in the opposite direction; a plurality of inner link pivotably connected to said links; a locking plate carried by each of said inner links; and, a first cutaway defined in an adjacent link and a second cutaway defined in a link so that when said links are in said interlocked position, said first and second cutaway define a locking plate recess for receiving said locking plate to interlock said links.
