With Actuator To Open Or Close Retainers Patents (Class 402/41)
  • Patent number: 9821594
    Abstract: A locking ring metal (10) includes binder rings (12, 14, 16) each formed by a pair of complementary shaped binder ring halves. Each ring half has an end attached to a frame (18, 20). The frames are movable relative to each other to open and close the binder rings. The frames are installed in housing (22) at one end of which a trigger (11) is mounted. A travel bar (34) installed within the housing above the frames and not connected to the trigger includes blocking elements (50) which, when in position, prevent movement of the frames to lock the binder rings in their closed position. A coil spring (48) attached to the travel bar and housing biases the travel bar in the direction to open the binder rings.

  • Patent number: 9511617
    Abstract: A ring binder mechanism for retaining loose leaf pages has a housing and pivoting hinge plates supported by the housing. The mechanism has an actuator mounted on the housing and moveable between open and closed positions to pivot the hinge plates and thereby open and close rings of the mechanism. An elongate travel bar is operatively connected to the actuator for movement of the travel bar longitudinally in the housing by the actuator. The travel bar has a plurality of locking elements and a cam. The locking elements are positioned to block pivoting movement of the hinge plates when the actuator and rings are in the closed position and the locking elements are in a locking position. The cam extends into an opening in the hinge plates. The cam helps the actuator drive pivoting movement of the hinge plates.

    Abstract: A ring binder mechanism includes a housing and a ring support supported by the housing for movement relative thereto. Each ring of a plurality of rings includes first and second ring members. The first ring member is mounted on the ring support for movement with the ring support relative to the housing between a closed position and an opened position. An actuator is mounted for pivotal movement relative to the housing for moving the rings from their closed position to their opened position. The actuator includes a lower arm having a contact surface engageable with a lower surface of the ring support when the rings are in their opened position and out of engagement with the ring support when the rings are in their closed position. The contact surface defines an angle between its outer surface and a horizontal plane between about 16 degrees and about 55 degrees.

    Abstract: A ring binder mechanism includes a housing and first and second hinge plates supported by the housing for pivoting movement relative thereto. A first ring member is mounted on the first hinge plate and moveable with the pivoting motion of the first hinge plate relative to a second ring member between a closed position and an opened position. An interlocking formation locks the first ring member and second ring member in the closed position. An actuator is mounted on the housing for movement relative to the housing. The actuator is adapted to pivot the first and second hinge plates and to translate the first hinge plate relative to the second hinge plate in a direction substantially parallel to a longitudinal axis of the housing.

  • Patent number: 7134800
    Abstract: A locking member for a loose-leaf binder includes a member having an integrally pivoted portion pivotally mounted in a first actuating member, an engaging projection which engages with an engaging recess of a second actuating member to prevent movement of the second actuating member. An elastic portion which abuts against an upper surface of a first base plate to urge the engaging projection to the engaging recess, first finger hooking portion, whereby under a condition where the binder rings are closed, movement of both the base plates are prevented against an opening forces acting upon the binder rings. When first finger hooking portion is pushed toward second finger hooking portion, the engaging projection is disengaged from the second actuating member against the elastic force of the elastic portion, and both of the base plates are then moved in such directions as to open the binder rings.

  • Patent number: 6916134
    Abstract: A safety ring binder mechanism helps prevent finger pinching by requiring simultaneous opposite movement of sliding actuators at both ends of the mechanism in order to open and close the rings. When the actuators are outermost, dimples on the actuators press the blades of the device against the housing, holding the rings open. When the actuators are pushed in, inclined tongues cam the ends of the blades downward, forcing the rings to close and holding them in a closed position.
