Embodiment Construction

[0042] like Figure 1 to Figure 5 As shown, the ring binder mechanism for fixing loose-leaf pages according to the present invention includes a housing 1, a hinge plate 2, a bar lock 3, a control handle 4, a pivot shaft 5, a spring 6, a ring element 7, an installation Column 8.

[0043] The shell 1 is a longitudinally extending rigid elongated plate with a groove feature in the middle, with a central longitudinal protrusion 10, a chute 11 formed on the opposite surface of the protrusion 10, two substantially opposite longitudinal edges 12, and two substantially opposite The transverse end 13.

[0044] The protuberance 10 has a molded recess 14 and a hole 15 near the two ends respectively.

[0045]The two longitudinal edges 11 form a uniform and generally arc-shaped raised profile from the outside to the inside, and are bent and protruded toward each other along the bottom of the profile. Positioning holes 16 are symmetrically distributed on the two longitudinal edges 11 .

Abstract

The invention relates to a ring binder mechanism. The mechanism includes a housing, supported by the housing, a hinged plate for pivotal movement relative to the housing, and a pair of semi-circular elements mounted on the hinged plate and movable between a closed clamp position and an open position; the above-mentioned The semi-circular element breaks through the hinge resistance of the hinge plate through the control handle and the bar lock fixed on the shell to open and close the clip. The binder mechanism of the present invention can overcome the defects of the prior art, save labor for opening and closing the folder, only need one hand to operate, and can be self-locked after opening and closing the folder.

Description

technical field [0001] The present invention relates to a loose-leaf folder, in particular to a ring-shaped belt binder mechanism for clamping loose-leaf pages, in particular to a binder mechanism with a self-locking mechanism that can be opened in one direction by a hand lever and closed by a hand lever . Background technique [0002] Existing loose-leaf folders usually include some buckles spaced apart from each other, each buckle is composed of two half-buckles, and each pair of half-buckles correspondingly provided can be opened or closed manually. When the clasp is open, papers can be slipped onto the file using the slots in the clasp half; when the clasp is closed, leaflets can be held and stored inside. When this kind of folder contains a large number of loose leaves or is impacted by external force, the buckle may automatically spring open, and the loose leaves in the folder will be thrown out of the jaw. [0003] Ring binders are used to secure loose-leaf pages, s...
