Patent abstract

A binder mechanism includes a rotatable support having ring segments that can be locked in a closed configuration. The binder mechanism includes a horizontal and/or a flush mounted push button that opens and/or unlocks the rotatable support. The push button acts on a ramped slider that causes the rotatable support to rotate open. An over-center arrangement aids in maintaining the binder mechanism closed or opened.
