DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper file in which paper is gathered with fasteners.

[0002]

2. Description of the Related Art There are various types of filing tools. Among the fasteners that can be used to replace the filed paper, there are a fastener that clips like a clip and a fastener that inserts a rod-shaped or ring-shaped claw through a hole in the paper (JP-A-2-293190, JP-A-5-1551
No. 73, Japanese Unexamined Patent Publication No. Hei 7-112594, Japanese Utility Model Laid-Open No. 6
-67075). However, all the fasteners are made of metal or synthetic resin, and when disposing of old files as garbage, it is necessary to separate the paper portion from these fasteners. It takes enormous amount of time and effort when sorting in large quantities, and is often discarded as it is without separation.

[0003] Filing tools that are conscious of the separation process are also found in some places (Japanese Patent Application Laid-Open Nos. 9-123660 and 9-123660).
272289, JP-A-9-286194). However, these are merely intended to facilitate separation by making them easy to remove, and there is no technical idea to make it possible to directly dispose of them in terms of materials. In the specification of the present application, a paper file refers to a sheet (paper) gathered with fasteners, such as an album, a loose leaf,
Catalogs, etc. The presence or absence of the cover does not matter.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a paper file which can be discarded without separating the fastener when the paper file is disposed of as garbage.

[0005]

The fastener of the paper file is a molded product of hard cardboard. As a hard cardboard, for example, I
According to EC standard 667, it is defined as a homogeneous product of homogeneous modified cellulose which does not peel off even after boiling for 30 minutes and has no interlayer.
It is a material that is treated the same as paper. For example, Fiber HB-77 (trade name, which is a product conforming to JIS C 2315 B) sold by Toyo Fiber Co., Ltd. is a paper made from cellulose as a raw material in a zinc chloride solution at an arbitrary thickness. Special paper with strong bonding between fibers, without any binder, etc., manufactured by self-adhesion utilizing the swelling action of fibers by zinc chloride, washing and drying processes. It is. This paper generates a small amount of harmful gas upon combustion, and the caloric content and ash content are at levels below ordinary levels. Furthermore, the modified cellulose as a main component is decomposed by microorganisms. The material can be formed into a curved or bent shape by punching with a press or pressing while applying heat after wetting.

A fastener as a molded product of hard cardboard may be constituted by a receiving member and a claw member. In this case, the receiving member is a vertically long member having grooves on both sides. That is, both sides of the vertically long flat plate of the hard cardboard are folded, and grooves formed by folded fins are provided on both sides. The claw member is formed by first punching a vertically long flat plate of hard cardboard into a comb shape having a continuous base located on one side in the longitudinal direction and a plurality of parallel claw pieces extending laterally from the base. Next, the engaging piece is formed by bending the claw piece upward with respect to the base and bending the tip end of the claw piece so as to be flush with the base. The receiving member and the claw member formed in this manner, after the paper is inserted into the claw member, the base of the claw member is inserted into one groove of the receiving member, and the engaging portion of the claw piece is inserted into the other groove of the receiving member. Fit and assemble. That is, the claw member can be slid into the receiving member.

[0007] The fastener may also be constituted by a claw piece formed by cutting and raising a part of a file cover made of hard cardboard and a punching opening thereof. The file cover is often made of hard cardboard, but this material is used to constitute the fastener. That is, the file cover is rectangular as a whole in plan view, but the base end is connected to the main body of the cover, and the claw piece whose head and neck are formed by the narrow portion provided on the front end side, and the base end portion is Cut up as an axis. Then, a claw piece having a head and a neck narrower than the head is cut and raised on the distal end side, and at the same time, a punching opening provided with an overhang receiving portion is formed at a position corresponding to the neck. Then, the nail piece can be curvedly formed on the inner surface side of the cover, and the head can be inserted into the punched-out opening and engaged with the projecting receiving portion of the opening. In this manner, a kind of ring-shaped fastener is formed, and a file can be filed by attaching a sheet to the fastener.

In some cases, the fastener is formed only by a structure corresponding to the claw member. That is, first, a vertically long flat plate of hard cardboard is punched out in a comb shape, and a comb provided with a connecting band portion which is continuous in the longitudinal direction at the middle portion in the width direction and a plurality of parallel claw pieces projecting laterally on both sides thereof. Form a shape. Then
These nail pieces are curved so as to face upward, and the tips are formed so as to face or partially overlap. Since the left and right nail pieces face each other, the polymerization in this case is vertical polymerization.

[0009] The right and left nail pieces of the comb-like object may be formed with their positions shifted in the longitudinal direction. The pawls are curved upwards such that their tips are in an overlapping configuration when viewed from the longitudinal direction of the fastener. That is, the left and right nail pieces overlap in the longitudinal direction without their tip portions facing each other. When such a claw member itself is a fastener, the structure is simple, and it can be conveniently used as a simple filing tool. In addition, fasteners made of hard cardboard, in addition to those that can rotate and flip the paper like a ring-shaped one, insert the binding piece provided on the lower member through the hole from the lower side of the stacked paper, There is a type in which a sheet is releasably fixed by an upper member on the upper surface side of a sheet.

[0010]

FIG. 1 is a first embodiment of a loose leaf note 1 as one of paper files. The loose leaf note 1 includes a cover 2, a back cover 3, a spine 4, and a fastener 5, and reference numeral 6 denotes a sheet. The cover 2, the back cover 3 and the spine 4 are made of cardboard, and the fastener 5
Is made of a fiber board (the above-mentioned fiber HB-77). The fastener 5 includes a receiving member 7 and a claw member 8 (FIG. 2). The receiving member 7 is provided on both sides of a vertically long flat plate by folding back both sides of a long plate. The claw member 8 is composed of a vertically long flat plate of fiber bird.
By punching with a press, a comb-like body having a continuous base portion 11 located on one side in the longitudinal direction and a plurality of parallel claw pieces 12 extending laterally from the same is made, and then swelled with water. Then, the engaging portion 13 is formed by bending the claw piece 12 upward with respect to the base portion 11 by bending the tip portion of the claw piece 12 so as to be flush with the base portion 11 by press forming with heat. .

Then, the receiving member 7 and the claw member 8 are placed in the one groove 10 of the receiving member 7, and the engaging portion 13 of the claw piece 12 is received in the other groove 10 of the receiving member 7. To be fitted and assembled (Fig. 5). Even after assembly, the claw member 8 can slide with respect to the receiving member 7, but does not come off with an inertia force of a normal swing due to friction between the fiber boards. In FIG. 5, reference numeral 14 denotes a reinforcing plate, which is attached to increase the rigidity of the base 11. The back surface of the receiving member 7 is attached and fixed to the inner surface of the spine 4, and the paper 6 is loaded on the claw pieces 12 of the claw member 8. Then, the claw member 8 is inserted from one end of the receiving member 7, and the whole is mounted on the receiving member 7 by sliding, so that the loose leaf notebook 1 is completed.

Since the engaging portion 13 at the tip of the claw piece 12 engages with the folded fin 9 and the engaged state is maintained by the elasticity of the curved claw piece 12, the paper 6 loaded on the claw piece 12 is maintained. Does not come out unexpectedly. On the other hand, if the paper 6 needs to be replaced,
Can be easily replaced.
In this embodiment, the curved shape of the claw piece 12 may be a part of an ellipse, a triangular shape with a rounded top, a square, or another polygonal shape in addition to the arc as shown in the figure.
Also, the planar shape of the engaging portion 13 at the tip of the claw piece 12 is not limited to a simple rectangle, and the side on the insertion side is inclined (FIG. 6A).
It may be rounded (FIG. 6B). With this configuration, the claw member 8 can be smoothly inserted into the groove 10 of the receiving member 7 with low resistance. In a filing that does not require a cover, the receiving member 7 and the claw member 8 are used independently as they are.

FIG. 3 shows a second embodiment, in which a loose leaf note 1 as a paper file is shown. The cover 2 of the notebook 1 is made of fiberboard, and the fastener 5 is directly formed on the inner surface of the cover 2. That is, the fastener 5 is a nail piece 12 formed by cutting and raising a part of a hard cardboard file cover and a punching opening 15 thereof (FIG. 4). It has a portion 16 and a narrower neck 17, and the punching opening 15 is provided with an overhang receiving portion 18 at a position corresponding to the neck 17. The nail piece 12 is formed into a curved shape on the inner surface side of the cover 2, and its head 16 is extended and the receiving portion 1 is formed.
8 is engaged.

The distance (L2) from the base end of the punching opening 15 to the overhanging receiving portion 18 substantially corresponds to the radius of the claw piece 12 assuming that the claw piece 12 is curved in a semicircular arc shape. 2 / 3.14 of total length L1 of opening 15
(Approximately 0.6 * L1). However, this value depends on the size of the head 16 and the curved state of the claw piece 12. When attaching the paper 6 to the fastener 5, as shown by reference numeral 5a in FIG. 3, the nail piece 12 of the fastener 5 is raised and inserted into the binding hole of the paper. 16 is engaged with the overhang receiving portion 18 of the punching opening 15. Head 1
6 cannot be disengaged unless it is returned to the proximal side.

In this embodiment, the fastener 5 can be formed by simply processing the material of the cover 2, and can be provided at low cost. Further, when the file is closed, the curvature of the claw piece 12 is temporarily crushed. This causes the head 16 of the claw piece 12 to tend to deepen the engagement with the overhang receiving portion 18 (FIG. 8). The existing paper 6 does not come off.

FIG. 9 shows a third embodiment, in which the fastener 5 corresponds to only the claw member 8 described above. That is,
A comb-like object formed by punching a vertically long flat plate of hard cardboard into a comb shape and having a vertically continuous connecting band portion 19 in the middle portion in the width direction and a plurality of parallel claw pieces 12 extending laterally on both sides thereof. 2
0 is formed (FIG. 9A). Next, the nail pieces 12 are curved so as to face upward, and the tips are formed so as to face or partially overlap (FIG. 9B). Since the left and right nail pieces 12 face each other, the polymerization in this case is a vertical polymerization.
The fastener 5 is used alone, and the paper is inserted by pushing and expanding between the opposing nail pieces 12. It is lightweight and can be used only to organize loose-leaves, to post and store note papers, etc.

FIG. 10 shows a fourth embodiment. Compared with the third embodiment, the left and right nail pieces 1 of the comb-like object 20 are shown.
The difference is that 2a and 12b are formed so as to be displaced in the longitudinal direction. And although the nail pieces 12a and 12b are curved upwards, when the fastener 5 is viewed from the longitudinal direction, these tips are arranged so as to overlap each other. That is, the left and right nail pieces 12a and 12b do not face each other, and therefore overlap in the longitudinal direction. The usage is the same as that of the third embodiment. However, since the positions of the left and right nail pieces 12a and 12b are shifted in the longitudinal direction of the fastener 5, the nail pieces 12a of the one side The spacing is wide and loose leaves can be easily inserted.

FIG. 11 shows a fifth embodiment, in which the fastener 5 corresponds to only the receiving member 7 described above. The fastener 5 includes a backboard 21 made of hard cardboard, a backing plate 22 and a binding string 23 made of leather or vegetable fiber. The back plate 21 is a vertically long flat plate, and both sides are folded to the back side for reinforcement to form reinforcing ribs 24. Further, binding holes 25 are formed in a line at the center in the width direction. The backing plate 22 is a similar vertically long flat plate, and has binding holes 26 formed at both ends.

When the loose leaf is to be bound, it is placed on the back plate 21 with the back side edges aligned, and both ends of the binding string 23 are passed through the binding hole at the center of the loose leaf to the back side.
Both sides of the binding string 23 are respectively passed through the binding holes 25 at the center of the back plate 21 to the back side.
Through the binding hole of the loose leaf from the other binding hole 25, and finally put the backing plate 22 from above the loose leaf that has been bound, and put both ends of the binding string 23 inside from the binding holes 26 at both ends of the backing plate 22. And tie the two sides together. While the structure as the fastener 5 is extremely simple, the loose leaf can be securely bound, so that it is not unintentionally scattered.

In the drawings, some parts are exaggerated for clarity of the structure, and some parts are different from actual parts. In addition, the colors are free for each member, and the nail pieces 12 and the like can be yellow, pink, and the like, not metallic, and can create a softer atmosphere than ever before. Further, in this embodiment, the number of the nail pieces 12 is two on each side and is not limited. As a form of binding the paper, only a necessary one of the many nail pieces 12 is raised, and the other pieces may be used while being pressed flat.

Although the above description has been made of a fiberboard as a material, any cardboard which is generally hard and has elasticity can be used. In addition, although the above-described embodiments have all proposed that the claw pieces 12 are curved in a ring shape, the invention of the present application discloses that the tip of the claw pieces 12 that pass through the spelling holes from the lower surface side of the collected paper is It is also applicable to a configuration in which the sheet is bent by another member made of hard cardboard on the upper surface side to prevent the sheet from slipping out.

[0022]

According to the first aspect of the present invention, since the fastener is a molded article made of hard cardboard, the fastener can be discarded without separating the fastener from the paper file. Separation work can be omitted, and confusion caused by being discarded without being sorted can be avoided. According to the configuration of claim 2, in addition to the need for separation,
The fiberboard as a material is hard, durable against abrasion and bending and elastic, and has good moldability for maintaining a bent or curved state, so that a durable and easy-to-use fastener can be made.

According to the configuration of the third aspect, in addition to the need for separation, the paper can be detached by inserting and removing the claw member with respect to the receiving member, and can be used similarly to the conventional ring-shaped fastener. Further, it is easy to process and color, and a colorful fastener can be provided at low cost. Claim 4
According to the configuration described in (1), in addition to the necessity of sorting, the cover and the fastener of the file are integrated, and the fastener can be formed by pressing the cover, so that the configuration can be simplified and provided at a lower cost.

According to the constitutions of the fifth and sixth aspects, in addition to the necessity of separation, since the claw member itself is a fastener, the structure is simple and can be conveniently used as a simple filing tool. According to the configuration of claim 7,
In addition to the necessity of separation, since there is no thinner portion such as a nail piece as a fastener, a strong fastener can be obtained. In addition, it is a filing that is reliable without fraying.
