DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a file for binding and holding a sheet such as a document, and more particularly to a file whose width of a spine can be adjusted according to the thickness of the sheet.

[0002]

2. Description of the Related Art In general, when there are a plurality of sheets such as documents, it is inconvenient to refer to and search the sheets in a state where the sheets are separated, and the sheets are stored in a file. As shown in FIG. 4, an example of the file is a binding section b for binding the binding end portion a1 of the sheet body a, and when the sheet body a is bound to the binding section b, the sheet body a Is the back cover d that covers from the back side c
A piece e connected to the back cover d and protruding inward of the file (the binding side of the sheet body) and provided with the binding portion b; and the sheet body a connected to the piece e and connected to the sheet body a
Is bound from the fold line f to cover the binding portion b side of the sheet member a and the front side h.
And a cover i covering the front cover.

[0003] Therefore, this file is stored in a sheet a
Is bound, and the front cover i is bent toward the front side of the sheet a, and the sheet a is surrounded by the back cover d, the back cover g, and the front cover i and stored.

As shown in FIG. 4, the binding portion b pierces the binding end portion a1 of the sheet member a and binds the hole j through a string or a linear member b1 made of resin or metal. There is a type having a binding tool and a type having a binding tool that clamps a binding end portion of the sheet body a.

The file shown in FIG. 4 is manufactured by bending an integral substantially rectangular plate material. When manufacturing this file, first, this plate is bent inward in a valley fold → mountain fold → valley fold inward from a longitudinal end portion of the plate material at a length corresponding to the width of the back cover d so that the plate material is doubled. Is formed. Further, the plate material is bent toward the piece e at the fold line f at a position opposite to the back cover d with the piece e interposed therebetween to form the spine g and the cover i. Next, the binding portion b is attached to the piece e to form a file.

[0006] In this type of file, the thickness of the sheet body to be bound is various, and if a plurality of files having various spine widths are prepared in accordance with the thickness, management and cost are reduced. Problems arise in terms of performance. On the other hand, conventionally, various files that can adjust the spine width have been proposed.

One of them is a file with a heading sheet of Japanese Utility Model Publication No. 2-15663 (first prior art). This is a file having a first cover plate in which a cover plate and a spine plate are integrally formed, and a second cover plate in which a bag-shaped portion for accommodating the spine plate is formed. A document is sandwiched between a first fold piece near the boundary of the spine board and a second fold piece of the second display panel, and the document is bound through binding holes in eyelets of each fold piece and a hole of the document. This file has a structure in which the spine board can be brought out to the outside by adjusting the depth at which the spine board is inserted into the bag-shaped portion, to a size suitable for the thickness of the document to be bound.

[0008] Another one is Japanese Utility Model Publication No. 56-4206.
No. 7 (the second prior art). This is because an elongated hole is formed at a position near one side edge of the back cover (base plate), the back cover portion outside the elongated hole is bent inward, and overlaps with the back cover portion inside the elongated hole. By doing so, a bag portion covered by the outer back cover portion is formed to constitute a binding device main body, and a cover plate (covering plate) in which a connecting plate is extended to one side edge separately from the device main body. The connecting plate can be pulled out and inserted into the bag through the elongated hole. In this binding apparatus, the insertion and removal dimensions of the connecting plate are changed according to the thickness of the document, and the width of the spine is changed.

Further, another one is disclosed in Japanese Utility Model Application Laid-Open No. 63-801.
No. 73 (the third prior art). This is equivalent to a so-called magazine file that binds a booklet on a spine with a binding strap band bonded to the upper and lower edges. The spine and cover (Otsu cover) are connected, and the thickness of the booklet to be bound is The cover that protrudes in the booklet width direction is bent inward accordingly.

[0010]

However, each conventional file in which the spine width can be adjusted according to the thickness of the document to be bound has the following problems. In the first and second prior arts, when adjusting the width of the spine according to the thickness of the document, the binding must be removed once and the other cover body must be pulled out from one cover body by an appropriate amount. Work is complicated and time-consuming. In addition, each of the techniques has a problem that one cover body and the other cover body must be separately manufactured, which increases costs.

Further, in the third prior art, since the fold piece of the cover folded inward is not stopped, the fold piece may expand in an attempt to return to the original state, and it is easy to bend and the appearance is deteriorated. Cheap. The third prior art is a so-called magazine file, in which the contents to be bound are limited to a booklet, and the use of the file as a file is narrow.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and can be used for the entire sheet body, can adjust the spine width with a simple operation, and has a good file condition. The problem is to provide a file that becomes

[0013]

The present invention has the following arrangement to solve the above-mentioned problems. According to the present invention, a binding portion for binding one end of a sheet body such as a document, the binding portion is fixed, and when the sheet body is bound to the binding portion, the sheet body is covered from one side. The first cover body is connected to the first cover body, and is bent from a fold line when holding the sheet body, and can cover from one end side to the other surface side of the sheet body. A file having a second cover body, wherein the second cover body has a plurality of parallel folding lines formed at least on a part connected to the first cover body and on a part opposite to the first cover body. When the end portion of the opposite side portion of the second cover body is bent along a fold line, the folded end portion bent from the fold line is detachably sandwiched to change the bent state of this end portion. Characterized by having a holding device for holding It is a file.

Further, in the present invention, the holding member is made of a transparent resin, and the sheet piece may be inserted so as to be visible from the outside.

[0015]

According to the present invention, the second cover body includes at least a part connected to the first cover body and a part opposite to the first cover body.
A plurality of parallel folding lines are formed. For this reason, the second cover body may be bent from a fold line corresponding to the thickness of the sheet body, and the portion of the second cover body closer to the first cover body from the fold line may be used as a spine part. The remaining part can be used as a cover. Therefore, the spine width can be adjusted by a simple operation according to the thickness of the sheet member.

When the end of the opposite side of the second cover is bent along a fold line corresponding to the end of the first cover, for example, the end of the second cover is bent from the fold line by the holding member. Since the overlapped end is detachably sandwiched and the bent state of the end is maintained, it is possible to prevent the bent portion of the end of the second cover body from expanding or the second cover body from being curved. be able to. If the holding device is made of a transparent resin and a sheet piece such as a paper piece can be inserted so as to be seen from the outside, it is necessary to find the sheet piece and confirm the contents of the file with good visibility. Can be.

[0017]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is an overall explanatory view of a state in which the file of the embodiment is opened, FIG. 2 is a partial explanatory view similarly, and FIG. 3 is an explanatory view of using the file. This embodiment is a file for binding a sheet body 10 such as a document as shown in FIG. 1, and is mainly composed of a binding unit 12, a first cover body 14, and a second cover body 18.

That is, the binding section 12 is provided with the sheet 1

Can be used to bind the cord 12a to the hole 12b, and a linear member made of resin or metal can be attached to the hole 1b.
A type having a binding tool for binding through 2b can be used. Further, the binding end portion 10 of the sheet body 10
It is possible to use a binding tool that clamps a.

The first cover body 14 has the binding section 12 fixed thereto, and when the sheet body 10 is bound to the binding section 12, the sheet body 10 is placed on the back side (one side; 1 (from the lower side in FIG. 1).
The binding portion 12 is fixed to the first cover body 14 by connecting the first cover body 14 integrally with the first cover body 14 and projecting into the file inside a piece 20 (the same as the piece e in FIG. 4). To be formed). Preferably, the piece 20 is fixed in contact with the binding-side end of the first cover 14.

Further, the second cover 18 is connected to the first cover 14 and the sheet 1 is attached to the binding portion 12.
When the “0” is bound, the sheet 10 is bent from an appropriate folding line 16 and covers the sheet body 10 from the binding end 10 a side to the front side (the other surface side) B. Second cover body 18
Is connected to the first cover 14 via the piece 20. Further, in the second cover body 18, a portion covered adjacent to the binding end portion 10a becomes a spine portion 101 similar to the spine cover of a general file, and the other portions are cover covers of a general file. Cover section 102 similar to

Here, the file of the embodiment has a well-known configuration in which the basic part is manufactured from a plate material such as paper, resin or the like having a substantially rectangular shape. The valley fold → the mountain fold → the valley fold from the longitudinal end toward the inside (toward the sheet body 10 binding side) at a position having a length corresponding to the width of the first cover body 14, and the plate material is doubled and protrudes. One piece 20 is formed. Further, the portion on the opposite side of the first cover 14 with the piece 20 therebetween is bent toward the piece 20 to form the second cover 18. In this case, the boundary between the first cover 14 and the piece 20 is bent to form a first corner (first boundary corner) 22, and the second cover 18 and the piece 20 are formed. Is bent to form a second corner portion (second boundary corner portion) 24. According to the file of the embodiment, the respective ridge lines of these boundary corner portions 22 and 24 face outward and It is formed close to or in contact with. A file is constructed by attaching the binding section 12 to the piece section 20.

In the file, the second cover 1
A plurality of parallel fold lines 16 are formed over the entire surface of 8, that is, from the portion connected to the first cover 14 to the portion on the opposite side. The fold line 16 is formed parallel to the ridge line of the first and second boundary corner portions 22 and leaving both end portions. For example, the second cover 1
8 has a groove-shaped concave or convex portion formed on one or both surfaces.

As shown in FIG. 2A, the file is appropriately folded at an end 18b of the second cover 18 opposite to the end 18a connected to the second cover 14. Line 1
6 can be bent toward the inside of the file. Further, when the opposite end portion 18b was bent along the folding line 16, the bent portion (return piece) 18c of the second cover body 18 was in contact with and overlapped the inside of the second cover body 18. There is provided a holding member 28 for detachably holding the end 18b from the direction of the bent tip (fold crest) 26 to maintain the bent state of the end 18b.

As shown in FIG. 2A, the holding member 28 has a substantially belt-like shape as a whole, a substantially C-shape having a cross section viewed from the longitudinal direction which is narrow in the thickness direction, and an opening end thereof. Is narrower than twice the thickness of the second cover 18. In addition, the holding member 28 is preferably made of a material that can be elastically deformed. In this case, after the holding member 28 is attached to the second cover 18, the folded piece 18 c can be held with a strong force. it can.

The holding member 28 is made of a transparent resin. As a result, as shown in FIG. 2B, a paper piece (not shown) 30 on which information (such as a title) related to the file is written is inserted between the holding device 28 and the second cover 18. And the heading.

Next, the function of the file according to the embodiment will be described. In the file, first, as shown in FIG. 1, the sheet body 10 is bound to the binding unit 12. Thereafter, the second cover 18 is covered from the binding end 10 a of the sheet 10 to the front side. In this case, as shown in FIGS. 3A and 3B, the end 18a of the second cover 18 connected to the first cover 14 is adjusted according to the thickness of the sheet 10. Fold along the folding line 16 (16a). In the second cover 18, the first cover 14 is separated from the fold line 16 a.
A portion extending from the fold line 16a to the front end of the second cover body 18 (a portion extending from the opposite end portion 18b) to the portion connecting to the front cover portion 181.
2 and covers the surface of the sheet body 10 like a well-known cover. In this manner, the width of the spine 181 can be adjusted by a simple operation of bending from the appropriate folding line 16.

As shown in FIG. 2, the opposite end portion 18b is formed by bending a folded piece 18c inward from a fold line 16a corresponding to the width of the sheet body 10, for example, at an appropriate fold line 16 to form a fold 26. Then, the holding member 28 is fitted to the bent end portion including the fold 26. Thus, the width of the second cover 18 can be adjusted to a width suitable for the sheet 10 to be bound or the width of the first cover 14 by a simple operation. In addition, since the clipping member 28 is fitted to the bent end portion, it is possible to reliably prevent the bent folded piece 18c from expanding to return to its original state and the second cover 18 from being bent.

Here, the thickness of the sheet body 10 to be bound to the file varies depending on the amount. Sheet 1
When the amount of 0 is large, as shown in FIG. 3A, the fold line 1 separated from the ridge line of the first and second boundary corner portions 22
6a, the second cover body 14 is folded and the spine portion 18 is bent.
Increase the width of 1. When the amount of the sheet body 10 is small, as shown in FIG.
The second cover body 14 is bent from the fold line 16a near the ridgeline of the 24 to reduce the width of the spine portion 181. In this manner, the sheet body 10 to which the width of the spine 181 is to be bound
It can be adjusted freely according to the thickness of the paper.

As described above, as the thickness of the sheet member 10 changes, an appropriate fold line 16 at the opposite end portion 18b is selected and the folded piece 18c is bent, and the holding member 28 is attached thereto. Of course, it fits.

The above embodiment is a preferred example of the present invention. However, it goes without saying that the present invention is not limited to this. For example, the binding portion of the present invention is provided not only at a place where the first cover body and the second cover body are connected, but also at an appropriate place of the first binding portion (on the top of the sheet body,
Below, or on the opposite side of the portion where the first cover and the second cover are connected).

If the folding line of the second cover body is provided as a whole as in the embodiment, the width of the spine can be freely adjusted.
However, the present invention is not limited to this, and the effects of the present invention can be obtained only by providing the folding lines at both ends in the width direction of the second cover.
