Abstract
A ring binder, with a fixed bar (1), bearing hooks (2) and a moving bar (3), wherein the fixed bar (1) is immovably fixed on a spine plate of a folder; the bearing hooks (2) are fixed on the upper surface of the fixed bar (1); the moving bar (3) is movably lapped over one side of the fixed bar (1); the lower surface of the moving bar (3) and the lower surface of the fixed bar (1) are clamped and connected with each other; the moving bar (3) can rotate relative to the fixed bar (1) and slide along the length direction of the fixed bar (1); a spring (4) connected between the moving bar (3) and the fixed bar (1); and moving shackles (5) fixed on the upper surface of the moving bar (3). As the ring binder lacks a base plate, a housing, etc., both the opening and the closing of the binder are convenient and the cost of the ring binder is reduced.
Claims5
A ring binder, comprising:
- a fixed bar (1) and a moving bar (3), wherein the fixed bar (1) is configured to be immovably fixed on a spine plate of a folder;
- bearing hooks (2) fixed on an upper surface of the fixed bar (1);
- wherein the moving bar (3) is movably lapped over the fixed bar (1);
- such that the moving bar (3) and the fixed bar (1) are clamped and connected with each other;
- the moving bar (3) being capable of rotating relative to the fixed bar (1) and sliding along a length direction of the fixed bar (1);
- a twisted spring (4) having two ends and connected between the moving bar (3) and the fixed bar (1);
- and
- moving shackles (5) fixed on an upper surface of the moving bar (3),
- wherein overhead hooks (6) for limiting the moving bar (3) to only slide along the length direction of the fixed bar (1) are respectively formed on the fixed bar (1) and the moving bar (3), and the overhead hooks (6) on the fixed bar (1) and the overhead hooks (6) on the moving bar (3) are engaged with each other,
- wherein a clamp hook is respectively arranged on a lower surface of the moving bar (3) and a lower surface of the fixed bar (1), and wherein one end of the twisted spring (4) is respectively connected to the clamp hooks of the moving bar (3) and the fixed bar (1),
- wherein a plastic handle (7) for pushing the moving bar (3) is clamped and connected at one end of the moving bar (3),
- wherein an inner end face of the plastic handle (7) and an outer end face of the fixed bar (1) are each respectively provided with an overlapped portion and are in collision with each other in a fitting mode through the corresponding overlapped portions,
- wherein first bent saddles (8) for limiting binder opening travel of the moving bar (3) are respectively formed on the lower surface of the fixed bar (1) and the lower surface of the moving bar (3);
- the first bent saddles (8) on the fixed bar (1) and the first bent saddles (8) on the moving bar (3) are respectively extended to the lower surface of the moving bar (3) and the lower surface of the fixed bar (1);
- second bent saddles (8a) for limiting binder closing travel of the moving bar (3) are also formed on the lower surface of the moving bar (3) and lean against lower sides of the overhead hooks (6) on the fixed bar (1).
