A ring mechanism for retaining loose-leaf pages includes a housing and ring members for holding loose-leaf pages that are moveable relative to the housing between an open and closed position. An actuation system moves the ring members and includes hinge plates pivotally mounted on the housing and an actuator actuating pivoting movement of the hinge plates. A travel bar of the actuation system is moveable by the actuator between a locked position blocking pivoting movement of the hinge plates and an unlocked position allowing pivoting movement of the hinge plates. The actuation system is adapted to deform while moving the travel bar from the locked position toward the unlocked position to delay the pivoting motion of the hinge plates from the movement of the actuator.

A ring mechanism has pivoting hinge plates supported by a housing so pivoting of the hinge plates can open and close rings for holding the loose-leaf pages. The mechanism has an actuator including a lower arm for moving the hinge plates to open the rings and an upper arm for moving the hinge plates to close the rings. The upper arm has a hook thereon. An intermediate connector comprises a cross bar captured by the hook on the actuator. The intermediate connector connects a travel bar to the actuator so movement of the actuator to pivot the hinge plates causes longitudinal movement of the travel bar in the housing. A locking element is moveable with the travel bar between a locking position and non-locking position.

A ring mechanism has an elongate housing and rings for holding loose-leaf pages. Each ring has ring members mounted on pivoting hinge plates for movement between open and closed positions. An actuator has opening and closing arms extending from an actuator body for opening and closing the rings. The mechanism has a travel bar moveable between a locked position in which a locking element blocks pivoting movement of the hinge plates and an unlocked position. The actuator has a flexible arm positioned to push the travel bar toward the locked position when the actuator closes the rings. At least a portion of the flexible arm is adapted to deform during closing in a manner that includes rotation in a first direction relative to the body of the actuator. Movement of the actuator to close the rings includes rotation of the actuator in the first direction relative to the housing.

The present invention relates to a plastic plate clip, comprising a bottom plate (1), a hook (2) and a torsional spring (3). The hook comprises rotating shafts (21) provided on two sides of the front end, connecting portions (22) provided on two sides of the middle part, and a fixed portion (23) provided at the rear end, the two ends of each of the connecting portions being connected to an end of the respective rotating shaft and one end of the fixed portion, respectively. The bottom plate is a plastic plate, and the front end of the plastic plate arches upward to form an arc-shaped groove (11) into which the other end of the rotating shaft is inserted. The torsional spring is sleeved onto the rotating shaft, and one end of the torsional spring is riveted to the rotating shaft while the other end thereof detachably presses against the bottom plate. The hook is hinged to the bottom plate through the rotating shaft. During assembly of the plastic plate clip, the spring is pressed into the arc-shaped groove to automatically implement pre-tightening of the spring, thereby facilitating the assembly and disassembly, and saving the cost.

A ring mechanism has an elongate body made of a moldable polymeric material and rings for holding loose-leaf pages. Each ring includes a first ring member and a second ring member. The first ring members are movable relative to the housing and the second ring members between a closed position and an open position. At least one ring member for each ring is a separately formed ring member and comprises a ring portion and an anchor connected to the ring portion. The at least one separately formed ring member is formed separately from the body. The anchor of the separately formed ring member is secured to the body for pivoting movement relative to the body. The anchor can be received in a receptacle in the body adapted to receive the anchor.


The present invention discloses a reversible temperature-changing and erasable neutral ink component and its manufacture method, which comprising by weight of composition as follows: (a) 3050 by weight of reversible temperature-changing pigment; (b) 25 by weight of shear thinned viscosity regulator; (c) 05 by weight of viscosity stabilizer; (d) 520 by weight of moisture wetting agent; (e) 0.050.5 by weight of antiseptic antimildew agent; (f) 14.572.95 by weight of deionized water; the all weight of the composition of (a)(f) are 95100% percent of total weight of the component. The neutral ink of the present invention has excellent writing performance, instant erasable, long time erasable and excellent rewriting performance.

A ring mechanism has a housing and rings for holding loose-leaf pages. Pivoting hinge plates are supported in the housing. Each ring includes a pair of ring members, at least one of which is mounted on a hinge plate and movable to open and close the rings. A travel bar carries a plurality of locking elements or wedges. The travel bar is secured to the housing in a manner that limits vertical movement of the travel bar while allowing the travel bar to translate between a locked position in which opening of the rings is blocked and an open position in which the rings are open. The travel bar is biased to remain in the locked position when it is in the locked position. The travel bar is free of forces tending to move the travel bar to the locked position when the travel bar is in the open position.

A ring binder for use in holding loose-leaf pages. A retaining system is configured to selectively and releasably hold first and second ring members in a closed position. First and second interlocking formations are selectively movable relative to one another between a retaining position and a non-retaining position. The first interlocking formation includes a projection having a free end. The free end has a void configured and arranged to permit resilient bending of portions of the free end of the projection in a first direction as they engage the second interlocking formation when the interlocking formations are moved from the non-retaining position to the retaining position. In the retaining position, the portions of the free end of the projection are substantially inhibited from bending in a second direction in response to pivoting movement of either of the ring members.

A ring binder mechanism for retaining loose-leaf pages includes an elongate housing, a first and second hinge plate, at least one ring for holding the loose-leaf pages, and an actuator mounted on the housing. Each ring includes a first ring member and a second ring member. The first ring member is mounted on the first hinge plate for movement with the hinge plate relative to the housing between a closed position and an opened position. The first hinge plate has a first hinge member and the second hinge plate has a second hinge member. The hinge members are disposed at a distance from the mid-plane that is the same as or less than the greatest distance between the upper surface and the mid-plane. An actuator is mounted on the housing for pivotal movement relative to the housing for moving the rings from their closed position to their opened position.
