The connection part 120 may have a length corresponding to the length of the base plate 110. The connection part 120 may be connected to the base plate 110 so as to be pivotable about the one edge of the base plate 110.

The fixing ring 130 may support a plurality of documents or support a plurality of inlays. The fixing ring 130 may be inserted into a through hole of a document or a through hole of an inlay of a transparent material into which the document is inserted, and may support the document or the inlay. One end (130E1) of the fixing ring (130) may be fixed to the connection portion (120), the other end (130E2) of the fixing ring (130) opposite one end (130E1) is detachable to the base plate (110) Can be combined together.

The fixing ring 130 may have a shape suitable for guiding the user's flipping of the document or the inlay. For example, the fixing ring 130 may extend from one end 130E1 of the fixing ring 130 to the other end 130E2 of the fixing ring 130 to have a ring shape in which a portion is cut off.

When the connection portion 120 rotates, the fixing ring 130 may rotate integrally with the connection portion 120. The fixing ring 130 is in an open state of the binder 100 in which the other end 130E2 of the fixing ring 130 is separated from the base plate 110 and the other end 130E2 of the fixing ring 130 It may be configured to rotate between the closed states of the binder 100 fastened to the plate 110.

When the fixing ring 130 is in the open state of the binder 100, the other end 130E2 of the fixing ring 130 is separated and spaced apart from the base plate 110, so that documents or inlays in the file folder are separated or inserted. Can be allowed. And, when the fixing ring 130 is in the closed state of the binder 100, the other end (130E2) of the fixing ring 130 is fastened to the base plate 110, the documents or inlays stored in the file folder is a binder Departure from (100) can be limited.

The binder 100 may include a single fixing ring 130 or a plurality of fixing rings 130. When the binder 100 includes a plurality of fixing rings 130, the plurality of fixing rings 130 may be arranged along the extension direction of the base plate 110. The plurality of fixing rings 130 are interconnected through the connection part 120, and when the connection part 120 rotates, the plurality of fixing rings 130 may rotate together.

As shown in FIG. 2 or 4, the binder 100 may include four fixing rings 130, but the number of fixing rings 130 is not limited thereto. For example, the binder 100 may include two, three, or five or more fixing rings 130.

In exemplary embodiments, a hook coupling hole 131 is provided at the other end 130E2 of the fixing ring 130, and the hook coupling hole 131 of the fixing ring 130 is engaged with the base plate 110. A locking protrusion 111 may be provided.

For example, the hook coupler 131 is protruding from one side of the other end 130E2 of the fixing ring 130 and may have a hook shape.

For example, the locking protrusion 111 may be provided on the upper surface of the base plate 110 and may provide an opening capable of accommodating the hook coupler 131. At this time, the locking jaw 111 is disposed on the movement trajectory of the other end 130E2 of the fixing ring 130, and when the fixing ring 130 is rotated, the locking jaw 111 is the other end of the fixing ring 130 (130E2) or may interfere with the hook coupling 131 of the fixing ring 130. The number of locking projections 111 provided on the base plate 110 may correspond to the number of fixing rings 130.

As the hook coupler 131 is engaged with the locking protrusion 111, the rotation of the fixing ring 130 is limited, and the closed state of the binder 100 may be maintained. In addition, as the hook coupler 131 is separated from the locking protrusion 111, the fixing ring 130 becomes a freely rotatable state, and the binder 100 can be switched from a closed state to an open state. The hook coupler 131 and the locking projection 111 will be described later in more detail with reference to FIGS. 6A to 6E, and FIGS. 7A and 7B.

A typical binder includes a metal material, and in particular, a fixing member into which a document or an inlay is inserted may be made of a metal material. However, the binder 100 according to exemplary embodiments of the present invention may be manufactured by an integral plastic injection method. That is, the base plate 110, the connection part 120, and the fixing ring 130 constituting the binder 100 may be manufactured by an integral plastic injection method, and the base plate 110, the connection part 120, And the fixing ring 130 may be made of the same plastic material. Therefore, compared to a general binder including a metal material, the binder 100 according to exemplary embodiments of the present invention can be produced at a relatively low cost, and the product cost of a file folder can be lowered.

6A to 6E illustrate a process in which the hook coupling hole 131 of the fixing ring 130 is coupled to the locking projection 111 of the base plate 110 in the binder 100 according to exemplary embodiments of the present invention. These are drawings showing in order. 6A, 6B, and 6E are perspective views showing a part of the binder 100, and FIGS. 6C and 6D are side views of the binder 100.

Referring to FIGS. 6A to 6E together with FIG. 2, the user presses the fixing ring 130 or the connecting part 120 to first press the fixing ring 130 so that the binder 100 is switched from an open state to a closed state. It can be rotated in the direction of rotation (eg, clockwise). The user rotates the fixing ring 130 in the first rotation direction until the hook coupling hole 131 of the fixing ring 130 is engaged with and fastened to the locking jaw 111, thereby locking the hook coupling hole 131 Can be fixed to (111).

Meanwhile, while the side fixing ring 130 of the hook coupler 131 is lowered with respect to the locking projection 111, it may include an inclined surface 133 in contact with the locking projection 111. The inclined surface 133 of the hook coupler 131 may allow the binder 100 to switch from an open state to a closed state more conveniently.

More specifically, as shown in FIGS. 6C and 6D, when the user presses the fixing ring 130 downward while the inclined surface 133 of the hook coupling 131 is in contact with the locking protrusion 111 , The hook coupling 131 moves downward and the other end 130E2 of the fixing ring 130 provided with the hook coupling 131 is bent in a first lateral direction D1 different from the user's pressing direction. I can. Subsequently, when the inclined surface 133 of the hook coupling unit 131 is off from the locking projection 111, the other end 130E2 of the fixing ring 130 by the restoring force of the fixing ring 130 itself, as shown in FIG. 6E. ) May be moved in a second lateral direction opposite to the first lateral direction D1, and as a result, the hook coupling 131 may be engaged with and fixed to the locking protrusion 111.

As described above, since the fixing ring 130 is made of a plastic material and has a predetermined elasticity, the hook coupling 131 can be easily deformed during contact between the hook coupling 131 and the locking projection 111. In addition, the hook coupler 131 may be fixed to the locking projection 111 by the restoring force of the fixing ring 130 itself.

7A and 7B illustrate a process in which the hook coupling hole 131 of the fixing ring 130 is separated from the locking protrusion 111 of the base plate 110 in the binder 100 according to exemplary embodiments of the present invention. These are perspective views in order.

Referring to FIGS. 7A and 7B together with FIG. 2, the user presses the fixing ring 130 in the lateral direction D1 so that the hook coupler 131 is separated from the locking projection 111. In this case, a marker may be provided on the base plate 110 to indicate a direction in which the hook coupler 131 is separated from the locking protrusion 111.

After separating the hook fitting 131 from the locking protrusion 111, the user rotates the fixing ring 130 in the second rotation direction (for example, counterclockwise) to make the binder 100 open. I can.

According to exemplary embodiments of the present invention, in a closed state of the binder 100 (that is, a state in which the hook coupling hole 131 of the fixing ring 130 is engaged with the locking projection 111), the fixing ring ( A direction for separating the hook coupler 131 of the 130) from the locking protrusion 111 may be different from the rotation direction of the fixing ring 130. For example, a direction for separating the hook coupling hole 131 of the fixing ring 130 from the locking protrusion 111 may be perpendicular to the rotation direction of the fixing ring 130. Since the direction for separating the hook coupling hole 131 of the fixing ring 130 from the locking projection 111 is different from the rotation direction of the fixing ring 130, the hook coupling hole 131 is unintentionally inserted into the locking projection 111 ) Can be prevented from being separated from.

As described above, exemplary embodiments have been disclosed in the drawings and specifications. In the present specification, embodiments have been described using specific terms, but these are only used for the purpose of describing the technical idea of the present disclosure, and are not used to limit the meaning or the scope of the present disclosure described in the claims.
