Problems solved by technology

[0005] However, such a typical loose-leaf folder requires a predetermined strength to hold the documents, thereby increasing the volume and production cost of the loose-leaf folder
[0006] In addition, due to the relatively simple structure and shape of this typical loose-leaf folder, it is limited in appearance and aesthetics.

Embodiment Construction

[0055] best practice

[0056] The loose-leaf folder of the preferred embodiment of the present invention will be described below with reference to the accompanying drawings.

[0057] Such as figure 1 ~Shown in Fig. 3, the loose-leaf folder 1 of the first preferred embodiment comprises a framework 3 for supporting loads, a plurality of pairs of semicircular rings 5 ​​which are arranged on the framework 3 and fix files by opening and closing, and the fixing framework 3 Fixing piece 7 at one end.

[0058] In the binder folder having the above structure, the frame 3 includes a first frame 11 and a second frame 13 arranged in parallel.

[0059] The first and second frames 11, 13 are in the shape of a cable with a predetermined strength. The first and second frames 11 , 13 are arranged up and down and connected by a connecting piece 9 .

[0060] The first frame 11 can be in a state of natural contact with the inner surface of the connecting piece 9 , and the second frame 13 can ...

Abstract

A ring binder is disclosed. The ring binder includes a pair of frames for supporting a load, a pair of semicircular rings arranged on the frames and provided at first ends with a protrusion and an insertion hole, respectively, the semicircular rings being coupled to each other by the protrusion inserted in the insertion hole and being opened and closed when the frames operate to file documents, and a fixing member in which first ends of the frames are fixedly inserted. According to the ring binder, even when a volume thereof is reduced, sufficient strength is maintained and thus the documents can be efficiently filed. In addition, the ring binder can be designed in a variety of structures and shapes.

Description

technical field [0001] The invention relates to a loose-leaf file folder, in particular to a loose-leaf file folder which improves its performance and ease of use by improving its structure and diversifying it. Background technique [0002] Binders are often used to store documents. According to the number of perforations on the document, the binder is divided into 2-hole or 3-hole binder. [0003] A typical loose-leaf folder includes a shell, a plurality of semi-circular rings and a frame. These semi-circular rings are hinged on the shell and engage with each other through relative rotary motion. The rings are connected. [0004] In the loose-leaf folder structure, when the user pushes or pulls the frame, the plurality of semicircular rings rotate toward the center, thereby engaging or separating from each other, so that the user can save or take out the files. [0005] However, such a typical loose-leaf folder requires a predetermined strength to fix the documents, ther...
