DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a binding portion of a document file or a binder.

[0002]

2. Description of the Related Art As shown in FIGS. 3 and 4, a binding plate 11 for adhering to a cover f of a file or the like is connected to a binding portion of a file or a binder, and both ends thereof are connected in a narrow state. A narrow band-shaped binding tool made entirely of a thin metal plate and having insertion pieces 12 and 12 is used. In this binding device, the fixing plate 11 is bonded and fixed to the cover f using an adhesive, and after inserting the holes of the document p into the insertion pieces 12, 12, the insertion pieces 12, 12 are bent over the document p. By doing so, the document p can be bound.

[0003]

Since a metal binding tool is used in the above-mentioned conventional binding portion, if the frequency of binding or removing a document is high, the flexibility of the insertion piece portion 12 is reduced. Failures, and eventually disconnects. Then, there is a problem that the hole of the document is easily cut at the edge of the insertion piece portion 12. Further, it is necessary to apply an adhesive to the fixing plate portion 11 in advance, and to apply a release paper 13 to the applied layer (see FIG. 4). There are also problems such as the inconvenience of bonding and the increase in production cost.

The present invention has been made to solve such a problem, and an object of the present invention is to insert a band for binding a document between a pair of latch portions provided on a cover that can be folded in half. Of course it can be detachably attached to the cover by one touch so that it only wears,
Convenience that documents can be bound and removed from either side of the front and back covers and no folding operation is required, and a durable synthetic resin strip is manufactured at low cost by using a punching die. It is an object of the present invention to provide a binding portion for files and the like that has been improved so that it can be used.

[0005]

In order to achieve the above object, a binding portion of a file or the like, which is a feature of the present invention, is provided on the inner surface of the front and back cover body which can be folded in half by the hinge portion. A pair of latching portions, each having a window hole, are provided so as to be able to be turned upside down and positioned on both the left and right sides, and between the latching portions, through each window hole of the latching portion. A strip for binding a document made of a synthetic resin having flexibility is removably inserted, and the flat portions formed at both ends of the strip have a substantially arrowhead-shaped locking portion. , Circumscribing each of the window holes of the above-mentioned latch portions,
It is configured so that it can be locked in the window hole.

In this configuration, the cover is made of synthetic resin, and the latch portion is formed integrally with the cover by cutting and raising a part of the cover in a U-shape. It is preferable in terms of manufacturing that the file and the binder can be provided at a lower cost, and the latch portion provided in this manner can be freely raised and lowered by its own flexibility.

According to this binding portion, the front and back cover bodies are opened, and the strip is inclined with respect to the window hole of the latching portion, as described later, so that the hooking portion on the front side extends from the window hole of the latching portion on the near side. When the strip is inserted horizontally toward the window hole of the stopper, and the strip is returned horizontally to the window hole after insertion, the locking portions at both ends of the strip formed substantially in the shape of an arrowhead are fixed to the respective windows of the double-stopping portion. It becomes possible to lock the hole in a circumscribed state. Therefore, if it is attempted to pull out the strip in any direction in this inserted state, the strip cannot be pulled out because one of the locking portions is locked to the edge of the window hole.

At the time when the strip is inserted into one of the window holes of the latch portion, the strip is inserted into the hole of the document to be bound, and then the strip is inserted into the window hole of the other latch portion. When inserted, the locking portions of the two strips are locked in the window holes of the both locking portions as described above, and the document can be bound between the cover bodies. Then, the strip cannot be removed from the latch unless the locking section is inclined and the locking section is forcibly removed from the window of the latch. Also,
The bound document has a handling advantage that it can be easily removed from either side of both cover bodies by removing one of the locking portions of the strip from the window hole.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. The strip 1 used for binding documents is made of a synthetic resin (for example, a material that does not generate dioxin when incinerated, such as polypropylene, is used) and has flexibility. Both ends of the strip 1 are formed into locking portions 2 and 2 having a substantially arrowhead-like planar shape, which can be locked in a window hole of a locking portion provided on the cover side of a file or the like described later. Have been.

On the other hand, both front and back cover bodies 4, such as a file and a binder, which can be folded in two by a hinge portion 3 such as a folding line.
5, a pair of latch portions 6, 6 is provided at the inner surface of the hinge portion 3 such that the pair of latch portions 6, 6 can be turned upside down with a gap therebetween.
Are provided with window holes 7, respectively. When the cover body is made of a synthetic resin (for example, polypropylene or the like), a part of both the front and back cover bodies 4 and 5 is cut into a U-shape with respect to the cover body, as shown in FIG. By raising, it can be formed integrally with the front and back cover bodies 4 and 5. Also, using a member in which the fixed plate portion and the movable plate portion in which the window hole is bored are provided so as to be able to be turned upside down, the fixed plate fixed portion is attached to the cover body by the movable plate portion. The latch portion may be provided on the cover body.
