PAPER SHEETS BINDING SYSTEM

摘要

A paper sheets binding system utilizes a two-part connector including a headed bifurcated inner ratcheted post binding member (18) and a headed pawls-containing locking collar (19) which is ratcheted down over the post member legs to cinch the heads either directly around punch-hole apertures in a paper sheets stack or against a pair of longitudinal binding strips (16, 17) on opposite marginal edges of the stack, with or without an affixed paper sheets cover. The post legs and pawls on the binding member (18) and locking collar (19), respectively, are offset from the center of their heads so that upon assembly on a paper sheets stack to be bound, the connector element heads are asymmetric with respect to the apertures in the punch-hole paper stack. This allows the connector to better withstand asymmetric loading which is present when a book is purposely opened or accidentally dropped.
