BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a file capable of easily and accurately binding sheets.

[0002]

2. Description of the Related Art FIG. 4 and FIG.
Those shown in are considered. In this case, the front cover sheet 111 and the back cover sheet 112 are separated from each other, and the back cover sheet 112 has a bag shape having an opening 112a on the binding source side, and the opening 11 is formed on the binding source side of the front cover sheet 111.
The extension part 121 which can be inserted into the 2a is provided.
21 in the opening 112a, the front cover 111
The extension portion 121 exposed between the back cover 112 and the back cover 112
13 is set.

In such a structure, the width of the spine cover 113 changes according to the amount of insertion of the extending portion 121, so that the paper sheet P2
This has an advantage that the thickness of the entire file can be appropriately changed according to the binding amount of the.

[0004]

By the way, in this type of file, it is customary to dispose the binding foot 103 and the binding foot locking portion 104 for binding the sheet P2, and therefore the illustrated file is , A binding piece 102 for sandwiching the paper sheet P2 is formed between the front and back sides of the front and rear covers 111 and 112, and the back cover 112 is provided with a binding leg 103 with its base end engaged. 111 to the binding foot 1
A binding foot locking portion 104 is inserted so that the leading end side of 03 is inserted and locked in a bent state.

However, in this way, with the sheet P2 inserted into the binding leg 103 and set on the back cover 112, the back cover 112 should be closed with one hand while being careful not to block the opening 112a. Cover 1 against opening 112a with the other hand while holding or lightly pressing
The feeding operation of the extension part 121 of 11 must be performed (refer to FIG. 6). Therefore, if the back cover 112 is firmly held or pressed, the opening 112a is narrowed and the resistance becomes large and the operation becomes heavy, and if the holding or pressing is performed so as to reduce the resistance, the operation becomes light, but the paper sheet P2
The state of gripping the back cover sheet 112 on which is set becomes unstable, and the work becomes difficult in any case. Moreover, as shown by the arrow in the figure, an operation of bringing the binding piece 102 on the front cover 111 side closer to the surface of the paper sheet P2 and an operation of swallowing the extending portion 121 into the opening 112a at a position deviated from the surface are shown. It is necessary to interlock with each other, and the binding foot 103 is inserted between the insertion holes 122 on the front cover 111 side.
And further, the extending portion 121 is maximally fed into the opening 112a at a position where the binding piece 102 comes into contact with the surface of the paper sheet P2, and a crease is formed along the opening edge at a portion indicated by X in the drawing. Therefore, the binding foot locking portion 104 is operated to bind the binding foot 103.
Must be locked in the bent state. Therefore, when the above-mentioned interlocking is not successful and the extension amount of the extension portion 121 which becomes the spine cover 113 is slackened, the same operation must be repeated after the folding habit is restored. However, the accuracy of the work also remains a problem. First, let the extension 121 swallow into the opening 112a to some extent,
It is possible to perform an operation of bending the binding leg 103 into a large curve and inserting the binding leg 103 into the binding piece 102 or the binding leg locking portion 104, but even in this case, since fine adjustment work is necessary, it is necessary to open the opening for adjustment. The feeding operation of the extension portion 121 is still heavy or unstable, and the movement of the binding leg 103 is also cramped so that it cannot be inserted into the insertion hole 122. Therefore, improvement in workability cannot be expected.

The present invention has been made in view of such a problem, and relates to a binding work accompanying addition and removal of paper sheets, and a new useful file capable of surely improving the convenience and accuracy of the work. Is to provide.

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention separates a front cover and a back cover from each other to form a bag shape with one opening to the binding source side and the other binding source. An extension portion that can be inserted into the opening is provided on the side,
With the extension part inserted in the opening and the extension part exposed between the front cover and the back cover is the spine cover, place the binding foot on the cover on the side where the extension part is provided. In the cover of the bag-shaped side, a binding foot locking portion is provided to insert the front end side of the closed foot and lock the binding foot in a bent state.

In such a structure, with the sheets inserted into the binding legs and set on the cover, the cover is held with one hand or pressed while the bag-like cover is held with the other hand. An operation of gripping and swallowing the extending portion of the cover on the side where the binding legs are arranged in the opening is performed. Therefore, even if the cover on the binding side is firmly gripped or pressed, the opening is not narrowed, and the bag-shaped cover does not need to be gripped so strongly that the opening is crushed because the sheet-like cover is not attached. Moreover, in this product, the boundary between the cover sheet provided with the extension and the base end of the extension is always at the folding position, and it is possible to make a crease in this part and raise the extension. Therefore, it is not necessary to re-fold it, and if the extension part is swallowed inside until the opening is located near the surface of the paper sheet, that position is the position of the binding foot by the binding foot locking part. At the stop position, the exposed amount of the extension, which is the spine, is also determined at the same time. Therefore, it is possible to prevent slackening of the extending portion and the like, and it is possible to accurately complete the binding work with one operation.

The term "paper sheet" as used herein is a concept including not only paper but also a clear file and the like.

As a concrete mode of implementation, a binding piece is formed at a position folded inside the binding sides of both cover sheets, and paper sheets are bound between both binding pieces and extended. The binding foot is arranged on the binding piece of the cover on the side where the section is provided, and the binding foot locking portion is arranged on the binding piece of the cover on the bag-shaped side. It is preferable to fix the sheet to a binding piece.

According to this structure, the operation of swallowing the extending portion attached to the cover on the side where the binding legs are provided is swallowed in the opening of the bag-shaped cover at the same time. It is an operation to bring the leaf close to the surface, and the binding foot is naturally inserted in the bag-shaped cover binding piece or binding foot locking part during that time, so the position where the binding piece hits the paper sheet is generally extended. The maximum amount of opening to the opening of the section is the maximum, and when the sheets are stopped by the binding foot locking section at that position, the exposed quantity of the extending section serving as the spine cover is also accurately determined.

In such a construction, it is particularly preferable to use the front cover on the side provided with the extending portion as the back cover and the front cover on the side of a bag as the front cover.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to FIGS.

The files of this embodiment are shown in FIGS.
As shown in, the front cover 11, the back cover 12, and the back cover 13
And a pair of binding pieces 2 provided on the cover sheet 1 for binding the paper sheets P therebetween, and a base end 31 is supported by one binding piece 2 and a front end side 32 is the other side. Binding piece 2
Binding leg 3 that is inserted through and the tip side 32 of this binding leg 3
And a binding foot locking portion 4 that locks the binding foot 3 in a bent state at the insertion portion.

One binding piece 2 is formed at a position folded inward from the inner surface of the edge portion of the back cover 12 constituting the cover body 1 on the binding source side, and the other binding piece 2 constitutes the cover body 1. It is formed at a position folded inward from the inner surface of the edge of the front cover 11 on the binding source side. In this embodiment, the front cover 11
Has an opening 11a on the binding source side and has a bag shape in which the other three sides are closed. The back cover 12 continues to the binding piece 2 at a position continuous with the binding source side edge portion. An extension portion 21 that can be inserted into the opening 11a of the front cover 11 and has a plurality of folds is formed in a direction orthogonal to the insertion direction. The double-sided binding piece 2 has an extending portion 21 of the back cover 12.
Is inserted into the opening 11a of the front cover 11 and is arranged face-to-face with a distance between which the required amount of paper sheets P can be sandwiched according to the insertion amount. The extending portion 21 exposed between the two 12 serves as the spine cover 13. Then, insertion holes 22 for inserting the binding legs 3 are provided at corresponding two positions separated from each other in the longitudinal direction.

The binding leg 3 is made of resin or the like, the base end portion 31 is wider than the insertion hole 22, and linear ribs 33 are formed on the tip end portion 32 along the longitudinal direction at a predetermined pitch. Have Then, from the back cover 12 side to the insertion hole 22 provided in the binding piece 2 of the back cover 12, the front end side 32 of this binding leg 3
Is inserted so that the base end 31 side can be supported by the binding piece 2.

The binding foot locking portion 4 is fixedly provided in the vicinity of the edge of the front cover 11 on the binding source side, and has a binding foot drawing opening at a position corresponding to the insertion hole 22 of the front cover 11. Then, an operation knob for selectively opening and closing the binding leg pull-out opening by sliding the binding leg 3 is provided (not shown).

In this file, therefore, the binding legs 3 are arranged with the base end 31 engaged with the cover sheet 12 on the side where the extension portion 21 is provided, and the binding legs are attached to the cover sheet 11 on the bag-like side. Three
The front cover 32 is provided with the binding foot locking portion 4 which is inserted through the leading end side 32 and is locked in a bent state, and the paper sheet P is inserted into the binding foot 3 and set on the cover 12. While holding or holding 12 with one hand, the other hand holds the bag-shaped cover 11, and the extending portion 21 of the cover 12 of the other party is swallowed into the opening 11a. Therefore, even if the cover sheet 12 on the side where the paper sheets P are attached is firmly grasped or pressed, the opening 11a is not narrowed, and since the bag-like cover sheet 11 side is not attached to the paper sheets P, the opening 11a is formed. It does not need to be gripped so strongly that it is crushed. Moreover, as shown in FIG.
1 is provided with a cover 12 and a base end 2 of the extension portion 21.
The boundary Y with 1a is always at the folding position, and since it is possible to make a crease at this position and raise the extension portion 21 in advance, it is not necessary to remake the crease, and the cover 11 is lowered. If the extension portion 21 is swallowed until the opening 11a is located near the surface of the paper sheet P,
The position becomes the position where the binding foot 3 is locked by the binding foot locking portion 4, and the exposed amount of the extension portion 21 that is the spine cover 13 is also determined at the same time. For this reason, it is possible to prevent the extension portion 21 from sagging and the like, and it is possible to accurately complete the binding work with one operation.

In particular, the binding piece 2 is formed at a position where it is folded inside the binding sides of both cover sheets 11 and 12, and the sheet P is bound between the binding pieces 2 and the extension portion is formed. The binding foot 3 is arranged on the binding piece 2 of the cover sheet 12 on the side where the 21 is provided, and the binding foot locking portion 4 is arranged on the binding piece 2 of the cover sheet 11 on the bag-shaped side. Since the locking portion 4 is fixed to the binding piece 3, an operation of swallowing the extending portion 21 incidental to the cover sheet 12 on the side where the binding legs 3 are provided in the opening 11a of the bag-shaped cover sheet 11 Is an operation to bring the binding piece 2 existing in the vicinity of the opening 11a close to the surface of the paper sheet P at the same time (see FIG. 3), during which the binding foot 3 naturally forms a bag-shaped cover sheet 1.
Since the binding piece 2 and the binding foot locking portion 4 of No. 1 are inserted, the position where the binding piece 2 hits the paper sheet P is approximately the maximum swallowing amount into the opening 11a of the extension portion 21, and at that position When the paper sheet P is stopped by the binding foot locking portion 4, the exposed amount of the extending portion 21 that becomes the spine cover 13 is also accurately determined. That is, the sheets P can be bound tightly without sagging the extending portion 21 which becomes the spine cover 13, and the bound state with a good appearance can be realized. Will be stored in a stable manner, and the shape of the entire file will not easily be lost.

Further, since the front cover 12 on the side where the extending portion 21 is provided is the back cover and the front cover 11 on the bag-shaped side is the front cover, the front cover 11 is opened to remove the paper sheets P. It can be particularly suitable for regular files to do.

The specific structure of each part is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

For example, in the above embodiment, the cover 12 on the side where the extension 21 is provided is used as the back cover, and the cover 11 on the bag-like side is used as the cover. In a file used in such a manner as to be added to the above, it is also effective to use the cover on the side provided with the extension portion 21 as the front cover and the cover on the bag-like side as the back cover.
