| 402019000 | RESILIENT SHEET RETAINER REQUIRING DEFLECTION FOR SHEET REMOVAL | 16 |
| 20090169287 | RING MECHANISM BIASED TO CLOSED AND LOCKED POSITION - A ring binder mechanism that retains loose-leaf pages and has ring members that readily lock together in a closed position, preventing accidental opening of the ring members and loss of pages. The mechanism comprises a housing that supports two hinge plates for pivoting motion that brings the ring members to either an open position or the closed position. The mechanism further comprises a control structure supported by the housing for causing the pivoting motion of the hinge plates. A spring plate is engageable with the control structure for urging the control structure to move toward a position blocking pivoting motion of the hinge plates when the ring members move to the closed position. | 07-02-2009 |

| 20100278583 | RING BINDER MECHANISM - A ring binder mechanism has a housing supporting first and second hinge plates and rings, each ring including first and second ring members. The first ring member is mounted one of the hinge plates and moveable with the hinge plate relative to the second ring member between closed and open positions. An actuating lever for opening the rings is mounted on a pin secured to the housing. Pivoting of the actuator moves a travel bar relative to the hinge plates. A blocking element is secured to the travel bar for conjoint movement therewith between a locking position in which the blocking element blocks pivoting movement of the hinge plates to open the rings and a non-locking position in which the blocking element does not block pivoting movement of the hinge plates to open the rings. A torsion spring on the pin biases the actuating lever to its closed position. | 11-04-2010 |

| 20120034019 | REFILLABLE NOTEBOOK WITH RELEASE MECHANISM - A binding mechanism assembly for binding a sheet item, the binding mechanism assembly including a backing member having an upper surface, and a binding member directly or indirectly coupled to the backing member. The binding member includes a protrusion shaped and located to protrude through a hole of a sheet item to be bound thereto. The binding member further includes a generally flexible flange that is manually movable into engagement with the protrusion to form a generally closed loop and thereby bind the sheet item thereto. The loop is rotatable relative to the backing member from a first position in which the loop is generally located above the upper surface to a second position wherein at least part of the loop is located below the upper surface. A release mechanism is provided for opening the loop. | 02-09-2012 |

Methods of manufacturing spring clamp binders also are described. | 09-04-2008 |
| 20110020053 | RING MECHANISM HAVING GUIDE FOR TRAVEL BAR - 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. | 01-27-2011 |
| 20110085846 | Ring Binder Mechanism - A ring binder mechanism includes an elongate plate having a longitudinal axis. Hinge plates are supported by the plate for pivoting relative to the elongate plate. Ring members are mounted on the hinge plates and moveable between a closed position and an open position. A control structure is supported by the elongate plate and controllably pivots the hinge plates to move the ring members between the closed and open positions. The control structure has a travel bar connected to the hinge plates for moving the hinge plates between the closed and open positions. A spring biases the travel bar toward the closed position. | 04-14-2011 |
