Embodiment Construction

[0050] Referring now to the drawings, and in particular to FIG. 1 , a ring binder mechanism according to the present invention is indicated generally at 1 . In FIG. 1 , a ring binder mechanism 1 is shown mounted on a binder 3 . Binder 3 includes a front cover 5 and a rear cover 7 which are hingedly mounted to spine 9 so that the covers can be moved to selectively cover or uncover loose-leaf pages (not shown) held by ring binder mechanism 1 . In FIG. 1 the ring binder mechanism 1 is specifically shown mounted on the back cover 7 of the binder 3 . It will be appreciated that the ring binder mechanism 1 may be secured to the front cover 5 or the spine 9 within the scope of the invention. Additionally, the ring binder mechanism 1 may be attached to objects other than binders without departing from the scope of the present invention.

[0051] Referring additionally to FIGS. 2 and 3 , the ring binder mechanism 1 generally includes an elongated housing (generally indicated at 11 ) ...

Abstract

The invention relates to a circular binder mechanism, comprising a shell, and a first and second hinge plates supported by the housing for pivoting movement. A first circular component is arranged on the first hinge plate, and the first circular component can move along with the pivoting movement of the first hinge plate between the closing position and the opening position opposite to a second circular component. An interlocking structure is used for lock the first circular component and the second circular component in the closing position. An actuator is mounted on the shell and moves opposite to the shell. The actuator is used for driving the first hinge plate and the second hinge plate to pivotally move, and to drive the first hinge plate to move along a direction that is basically parallel to the longitudinal axle of the shell opposite to the second hinge plate.

Description

technical field [0001] The present invention relates generally to ring binder mechanisms for holding loose-leaf pages, and more particularly to a ring binder mechanism having hinge plates that slide to unlock ring members mounted thereon and pivot to unlock Move the ring assembly to the open position. Background technique [0002] A typical ring binder mechanism is used to secure loose-leaf paper such as punched paper in folders or notebooks. Its basic feature is that it has a plurality of rings, each ring consists of two half-ring parts, and the ring parts are mounted on two adjacent hinge plates. Hinged plates connected together about a pivot axis and pivotable within the elongated housing to move a ring member mounted thereon between an open position and a closed position in which loose-leaf pages can be added or removed , can be used to hold loose-leaf pages when in the closed position and the loose-leaf pages can be moved along the ring. Opening or closing the ring p...
