An embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 3 and 6 to 8, the file of the present embodiment stores documents and other paper leaves in a cover body 1 having a front cover 11, a spine cover 12, and a back cover 13. It is provided with a plurality of pockets 3 capable of binding and a binding tool 2 capable of binding paper sheets.

As shown in FIG. 4, the cover body 1 is, for example, an integrally molded product made of resin, and is a plate-shaped body having a substantially rectangular shape as a whole. A hinge 14 is provided between the front cover 11 and the spine 12, and between the spine 12 and the back cover 13, respectively. The hinge 14 is a concave groove extending in the height direction of the front cover, that is, in the vertical direction of the front cover 11, spine 12, and back cover 13 when the file is erected. The thickness of the portion of the cover body 1 where the hinge 14 is present is thinner than the thickness of the other portions (front cover 11, spine 12 and back cover 13). The hinge 14 enables the front cover 11 and the back cover 13 to rotate about an axis extending along the height direction of the front cover 12 with respect to the back cover 12, respectively. The hinge 14 interposed between the front cover 11 and the spine cover 12 and the hinge 14 interposed between the spine cover 12 and the back cover 13 are substantially parallel to each other.

In the front cover 1, a through hole 15 for passing the binding tool 2 is formed at a portion straddling the hinge 14 interposed between the spine cover 12 and the back cover 13 or a portion adjacent to the hinge 14. There is. The through hole 15 is located in the middle portion of the front cover 1 in the height direction of the front cover, extends substantially parallel to the hinge 14 on the back cover 13 side, and has a width of 4 mm to 5 mm to the extent that fingers cannot be inserted. ) Makes a narrow slit. In the present embodiment, most of the slits 15 are located in the spine cover 12 adjacent to the back cover 13, and extend slightly beyond the hinge 14 to the back cover 13.

In addition, the inner edge of the back cover 13 of the front cover 1 is provided with an insertion hole 16 for inserting a tubular portion 251 protruding from the base portion 21 of the binding tool 2. As will be described later, the tubular portion 251 constitutes a binding rod 25 for binding paper sheets together with a shaft portion 252 protruding from the holding portion 23 of the binding tool 2.

The shape and depth of the groove of the hinge 14 interposed between the spine cover 12 and the back cover 13 are substantially uniform as a whole, and the thickness of the portion of the cover body 1 where the hinge 14 exists is the groove of the hinge 14. It is almost even over the entire length of.

On the other hand, the shape of the groove of the hinge 14 interposed between the front cover 11 and the spine 12 is not substantially uniform as a whole, and the thickness of the portion of the cover 1 where the hinge 14 exists is the same as that of the hinge 14. Not substantially uniform over the entire length of the groove. In the present embodiment, a thin portion 141 for reducing the thickness of the cover body 1 is provided in a part of the hinge 14 interposed between the front cover 11 and the spine cover 12. Needless to say, making the cover body 1 thinner means lowering the bending rigidity of the cover body 1 (hinge 14). The shape and depth of the groove in the portion of the hinge 14 other than the thin portion 141 is substantially equal to the shape and depth of the groove of the hinge 14 interposed between the spine cover 12 and the back cover 13.

The thin-walled portion 141 is realized, for example, by forming concave grooves on both the front and back surfaces of the cover body 1, that is, the outer surface side and the inward surface side, as shown in FIG. 5 (a). The concave groove of the portion of the hinge 14 other than the thin portion 141 is formed only on the inward surface side of the cover body 1 or only on the outer surface side. Alternatively, as shown in FIG. 5B, the depth of the groove of the thin-walled portion 141 of the hinge 14 may be deeper than the depth of the groove of the portion other than the thin-walled portion 141.

In the present embodiment, the intermediate portion of the hinge 14 on the front cover 11 side in the height direction of the cover is a thin portion 141 so as to face the through hole 15. The line segment connecting one end (upper end along the cover height direction) of the through hole 15 and one end (upper end) of the thin wall portion 141 is substantially orthogonal to the cover height direction which is the extension direction of the hinge 14. Similarly, the line segment connecting the other end of the through hole 15 (the lower end along the cover height direction) and the other end (lower end) of the thin wall portion 141 is also substantially orthogonal to the cover height direction. The dimensions of the thin portion 141 along the cover height direction substantially match the dimensions of the through hole 15 along the cover height direction.

The pocket 3 is a so-called clear pocket formed by, for example, a transparent or translucent thin resin film formed into a bag shape, in which one or a plurality of paper sheets can be inserted. The inner end of each pocket 3 is fixed to the region of the spine cover 12 near the front cover 11 by welding or the like.

The binding tool 2 is, for example, an integrally molded product made of resin, and is a back portion 22 that connects the base portion 21, the pressing portion 23 facing the base portion 21, and the inner end of the base portion 21 and the inner end of the pressing portion 23. And a binding rod 25 extending in a direction facing each other between the base portion 21 and the pressing portion 23.

The base portion 21 has a thin plate shape that expands in the front cover height direction and extends in the front cover width direction, that is, in the left-right direction of the back cover 13. The base portion 21 is a portion to be joined to the outer surface of the back cover 13 of the front cover 1 (the surface opposite to the inward surface facing the front cover 11). That is, as shown in FIGS. 2, 6 to 8, in the file of the present embodiment, the base portion 21 of the binding tool 2 is exposed to the outside of the cover body 1. The base portion 21 is fixed to the back cover 13 by adhesion, welding, or the like. A tubular portion 251 which is an element of the binding rod 25 projects from the surface of the base portion 21 on the side to be joined to the back cover 13. The tubular portion 251 is located on the outer side portion (upper end portion and lower end portion) along the cover height direction in which the base portion 21 expands. As described above, the tubular portion 251 is inserted into the insertion hole 16 formed in the back cover 13 and protrudes inside the cover body 1.

The back portion 22 expands in the cover height direction, and its outer dimensions are larger than those of the base portion 21 and the pressing portion 23. A hinge 24 is provided between the back portion 22 and the base portion 21. The hinge 24 is a concave groove extending along the height direction of the cover. The thickness of the portion of the binding tool 2 where the hinge 24 is present is thinner than the thickness of the other portions (base portion 21, back portion 22 and pressing portion 23). The hinge 24 enables the back portion 22 and the pressing portion 23 to rotate about an axis extending along the cover height direction with respect to the base portion 21.

The pressing portion 23 once approaches the back width direction, that is, the direction away from the base portion 21 and the back cover 13, and then curves and extends so as to be substantially parallel to the base portion 21 and the back cover 13. There is. The pressing portion 23 also has a thin plate shape that expands in the cover height direction and extends in the cover width direction. However, the outer dimensions along the cover width direction are smaller than those of the base portion 21. The shaft portion 252, which is an element of the binding rod 25, protrudes from the surface of the holding portion 23 on the side facing the base portion 21 and the back cover 13. The shaft portion 252 is located on the outer side portion (upper end portion and lower end portion) along the cover height direction in which the holding portion 23 expands.

When binding paper leaves using the binding tool 2, first, the pressing portion 23 and the back portion 22 are rotated to move the pressing portion 23 from the base portion 21 and the back cover 13 as shown in FIG. Pull apart. At this time, the shaft portion 252 protruding from the holding portion 23 is pulled out from the tubular portion 251 protruding from the base portion 21. In that state, the inner edge portion of the paper leaf is placed so as to be overlapped on the base portion 21 so that the tubular portion 251 is inserted into the binding hole previously drilled in the paper leaf. After that, the pressing portion 23 and the back portion 22 are rotated so that the pressing portion 23 faces the base portion 21 and the shaft portion 252 is inside the tubular portion 251 as shown in FIG. 6 or 7. Insert in. As a result, the tubular portion 251 and the shaft portion 252 become the binding rod 25, and the paper leaves are bound between the base portion 21 and the pressing portion 23.

The binding tool 2 attached to the front cover 1 has its base portion 21 bonded to the outer surface of the back cover 13, while its back portion 22 and pressing portion 23 pass through the through hole 15 from the inward surface of the back cover 13. Will also enter the inside. The hinge 14 in the binding tool 2 and a portion in the vicinity thereof enter the inside of the through hole 15. In particular, when the cover body 1 and the binding tool 2 are open as shown in FIG. 8 and the cover body 1 and the binding tool 2 are closed as shown in FIG. 6, the spine cover 12 of the cover body 1 and the binding tool 2 are closed. Although it is substantially parallel to the back portion 22 of the binding tool 2, the back cover 12 of the cover body 1 and the back portion 22 of the binding tool 2 may interfere with each other because the back portion 22 of the binding tool 2 is accommodated in the through hole 15. can avoid.

In the present embodiment, a file in which a binding tool 2 for binding paper leaves is attached to a front cover 11, a back cover 13, and a cover 1 having a spine 12 joined to the front cover 11 and the back cover 13. A storage portion (through hole 15) for accommodating a predetermined portion of the binding tool 2 (the hinge 24 and the back portion 22 in the binding tool 2) is provided at the boundary portion between the spine cover 12 and the back cover 13. Constructed the formed file.

According to the present embodiment, the binding tool 2 can be arranged as close to the spine 12 side of the cover body 1 as possible. Therefore, the paper leaves bound to the binding tool 2 also approach the spine cover 12, and the paper leaves bound to the binding tool 2 even if the cover widths of the front cover 11 and the back cover 13 are not too large. It is avoided that the outer edge portion of the front cover 11 or the back cover 13 protrudes from the front cover 11. That is, the cover widths of the front cover 11 and the back cover 13 can be further reduced to make the dimensions of the entire file compact.

Further, by exposing the base portion 21 of the binding tool 2 to the outer surface side of the back cover 13, it is possible to secure a larger inner dimension from the holding portion 23 of the binding tool 2 to the inward surface of the back cover 13. It is possible to bind a larger number of paper sheets to the binding tool 2 within the limited spine width.

Further, in the present embodiment, a through hole 15 is formed so as to straddle or be adjacent to the hinge 14 on the back cover 13 side of the front cover 1, while at least a part of the hinge 14 on the front cover 11 side is formed. Is provided with a thin portion 141 that makes the thickness of the cover body 1 thinner than that of the hinge 14 on the back cover 13 side. As a result, the bending stiffness of the cover body 1 (in other words, the operating force required for rotating) when the back cover 13 is rotated with respect to the spine 12, and the front cover 11 with respect to the spine 12. The bending stiffness of the cover body 1 at the time of rotation is substantially equal. Therefore, it is possible to avoid giving the user a sense of incongruity that the back cover 13 is soft when the back cover 13 is opened and closed, but the front cover 11 is hard when the front cover 11 is opened and closed.

The present invention is not limited to the embodiment described in detail above. For example, in the above embodiment, the accommodating portion for accommodating the predetermined portions 22 and 24 of the binding tool 2 is the through hole 15 penetrating the cover body 1, but as shown in FIG. 9, the accommodating portion is the spine cover 12. It is also possible to form a recess 17 that does not penetrate the cover body 1 at the boundary portion with the back cover 13, and to use this recess as an accommodating portion for accommodating the predetermined portions 22 and 24 of the binding tool 2. The recess 17 in the illustrated example is located at a portion of the spine cover 12 adjacent to the back cover 13. On top of that, the thickness of the portion where the recess 17 is present is thinner than the thickness of the other portion of the spine cover 12.

Further, the accommodating portions 15 and 17 for accommodating the predetermined portions 22 and 24 of the binding tool 2 are not located at the boundary portion between the spine cover 12 and the back cover 13, but at the boundary portion between the spine cover 12 and the front cover 11. It is also possible to form it. In this case, the base portion 21 of the binding tool 2 is joined to the outer surface of the front cover 11.

In addition, the specific configuration of each part can be variously modified without departing from the spirit of the present invention.
