Abstract

To fold the ring binder flat for storage, the ring binder includes a cover member having a rear spine portion to which the attachment mechanism is secured. The connecting mechanism includes a sheet metal member that maintains the first and second metal strips in side-by-side relation with their inner edges abutting one another. Each of the metal strips has first and second ring members rotatably connected thereto to permit the ring members to rotate about an axis transverse to the length of the metal strips to enable the ring members to be rotated from the sheet metal portion to a first upright position. In this position, the annular member is movable towards the opposite annular member on the other metal strip to form the connecting ring. An over-centre mechanism comprising a sheet metal part, a strap and a lower free end of the ring part enables the ring parts to be moved together in a snap action. The ring member is rotatable to a second position in which it lies substantially in the plane of the sheet metal member to form a substantially planar configuration in which the cover is foldable to a substantially planar configuration.
