ABSTRACT:
A rotatable locking mechanism used with ring systems that open similarly to the rings of a binder. A ring system has rings each having two ring halves and hinged leaves connected to each other and attached to each ring half respectively. The locking mechanism on the ring system presses against the leaves to prevent the ring halves from opening. A lock for the rings can comprise an Allen screw or a similar rotatable device located at the cover over the hinged leaves of a binder or a flip chart holder. Ideally, the device has a lip or similar raised area so it is not removable from an aperture in the cover of a binder or a lockable flip chart holder. Locking the rings provides security so users cannot take pages out of a binder or a flip chart holder.
