DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a file and a binding foot thereof, and more particularly, to a binding foot which does not damage a binding hole area of a document, and the binding foot is mounted on the inner side of a cover to be stored. The present invention relates to a file that can improve the handling property at the time.

[0002]

2. Description of the Related Art Conventionally, in an office or the like, a file having a band-shaped or string-shaped binding foot has been used. This file is configured so that binding holes formed by punching are formed at two places along one edge of the document, and the binding can be performed by inserting a binding foot into the binding hole.

FIGS. 7 to 10 show an example of a conventional file. In these figures, file 5
Reference numeral 0 denotes a cover 51 including a front cover 51A, a spine 51B, and a back cover 51C, a band-shaped binding foot 53 that is mounted through the back cover 51C, and the binding formed on the cover 51A and the binding. An engaging piece 54 is provided so that the foot 53 can be inserted therethrough.

As shown in FIG. 9, the binding foot 53 is composed of a base surface 55 and a binding margin forming piece 56 connected to the base surface 55. Then, the binding margin forming piece 56 is inserted into the hole 58 formed in the back cover 51C,
The base surface 55 acts as a stopper, so that the binding feet 53 can be fixed or mounted.

The engaging piece 54 is formed by partially cutting and raising two regions of the cover 51A, and a hole 59 formed when the engaging piece 54 rises from the cover 51A. The binding margin forming piece 56 is inserted from the free end side, and in this state, the document P can be bound as shown in FIG.

[0006]

However, in such a file 50, the base surface 55 is exposed on the outer surface of the back cover 51C with the binding feet 53 mounted. Therefore, for example, as shown in FIG. 10, when storing a plurality of files 50 in a cabinet or the like, the base surface 55 is easily caught on the edge of the spine 51B of the adjacent file 50, and handling during storage is performed. There was a disadvantage that the properties became extremely poor.

Further, as shown in FIG. 9, the conventional binding foot 53 lays down at an acute angle with respect to the base surface 55 with the binding margin forming piece 56 being inserted through the engaging piece 54. Therefore, the binding hole Pa of the document P takes a directional orientation following the binding margin forming piece 56. Accordingly, an excessive load is applied to the document P in this area by the side edge of the binding margin forming piece 56, which causes a disadvantage that the document P is easily torn from the binding hole Pa area. Such inconvenience becomes remarkable when the binding amount of the document P is as small as several sheets. That is, in the state where the binding amount of the document P is small, the binding margin forming piece 56 bends to a substantially horizontal direction and falls down as compared with the case where the binding amount is large, and the side edge of the binding margin forming piece is the document P. This is because it will bite into the binding hole Pa.

[0008]

SUMMARY OF THE INVENTION The present invention has been made in view of the inconvenience of the prior art, and has as its object to improve the handling by making it possible to fix the binding feet without exposing the binding feet on the outer surface of the cover. It is another object of the present invention to provide a file and a binding foot that can avoid a document damage factor due to a binding foot.

[0009]

In order to achieve the above object, according to the present invention, a band-shaped or string-shaped binding foot fixed to the cover with one end fixed is provided, and a predetermined spacing is provided from the binding foot. In a file in which an engagement piece is provided on a cover portion and a free end side of the binding foot is engaged with the engagement piece so that a document can be bound between the inner surface portion of the cover and the binding foot, the binding foot is The cover is fixed to the inner surface of the cover without penetrating the cover. With this configuration, a step or the like does not occur on the outer surface of the cover, and it is possible to avoid a risk of being caught by an adjacent file when storing the file. In addition, when the stored file is taken out, the relative movement between the cover sheets that come into contact with each other can be made smooth, and the handling at the time of taking the file in and out can be improved satisfactorily.

The present invention also relates to a binding foot including a base surface fixed to the cover of a file and a band-shaped or string-shaped binding margin forming piece extending from the base surface. A configuration is adopted in which a fixed area on the base surface side of the binding margin forming piece is provided with an angle restricting portion that takes an upright posture with respect to the surface of the cover at a boundary portion between the pieces. With such a configuration, especially when the binding amount of the document is small, both side edges of the binding margin forming piece do not bite into the binding hole, and therefore, the initial shape of the binding hole can be stably set. It will maintain and protect documents from torn.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A plurality of projections may be formed on the base side of the binding foot or on the inner surface of the cover facing the base side. By forming such projections, it is possible to secure a strong connection strength when the fixing side of the binding foot is welded to the cover, and it is possible to effectively prevent separation of the binding foot and the cover. .

It is preferable that the angle restricting portion is constituted by a raised portion that restricts the bent region from falling down on the base surface when the binding foot forming piece is bent relative to the base surface. Since the raised portion can be integrally formed by using a forming die of the binding foot, there is no cost burden.

Further, it is possible to adopt a configuration in which notches are formed in base surface portions corresponding to both sides of the base of the binding margin forming piece. In a state where the binding margin forming piece has bound a certain amount of documents, a force is applied to peel the base surface from the cover when the binding margin forming piece is tightened. This force is given by spreading from the base region of the binding margin forming piece to the base surface,
By forming the notch, the area of the base surface that is affected by the ripple effect can be reduced. Therefore, the connection strength between the base surface and the cover is also ensured from this point.

Further, the base surface and the binding margin forming piece can be connected to each other via a step, thereby facilitating the bending operation of the binding margin forming piece and maintaining the above-described connection strength. Can be planned.
