  • Patent number: 6116804
    Abstract: The rings of a loose leaf ring binder are selectively locked and unlocked by a locking member which travels within a slot on the spine of the ring binder. The leaf springs of the loose leaf ring binder have notches formed below a portion of the slot. Therefore, when a W-shaped locking prong of the locking member is aligned with the notches, the leaf springs can freely flex upwardly and downwardly allowing the rings of the loose leaf ring binder to open and close. However, when the W-shaped locking prong is not aligned with the notches, the W-shaped locking prong is urged against the leaf springs thereby maintaining the leaf springs in a downward position thereby locking the rings of the loose leaf ring binder in a closed position. The locking member further includes a locking tab to maintain the locking member within a locked position within the slot.
