Abstract
A ring mechanism has a housing having a guide formed by tabs extending down from a plateau of the housing. The guide is elongate in a direction extending lengthwise of the housing. Some of the tabs are spaced apart from each other longitudinally. The housing supports pivoting hinge plates. The mechanism has rings for holding loose-leaf pages. Each ring includes first and second ring members. The first ring member is moveable with the pivoting motion of one of the hinge plates between a closed position and an open position. A travel bar is restrained by the guide for longitudinal movement relative to the housing between a locked position and an unlocked position. The travel bar includes at least one locking element formed as one piece with the travel bar. The locking element is adapted to block movement of the hinge plates in the locked position of the travel bar.
