Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a resin file, and more particularly, to a resin file provided with a file main body having a pair of front mounting portions connected to each other with a backing portion interposed therebetween.

[0002]

2. Description of the Related Art Conventionally, a paper file is often used as a file for binding a large number of sheets. However, paper files have the following disadvantages. That is, the metal binding device is fixed to the spine portion of the thick paper file main body by rivets or the like, so that an assembling process for fixing the binding device to the file main body is necessary. Further, when the binding tool is riveted to the spine of the file body, the head of the rivet appears on the surface of the spine, which not only makes the appearance unpleasant, but also restricts the layout of titles or design printing. Furthermore, when sorting and discarding, the metal binding must be separated and discarded from the paper file body.
There was a problem that it took time and effort to dispose.

[0003] As a solution to such a problem,
Resin files have been proposed. For example,
No. 8-155271 discloses a back wall, a front wall connected to one long side of the back wall via a linear groove, and a front wall connected to the other long side of the back wall via a linear groove. There is shown a resin file which has a back wall having a rod-shaped binding tool on the inside, and these are integrally formed of synthetic resin. Japanese Patent Application Laid-Open No. Hei 6-340195 discloses that a resin file surface material and a resin binding tool are separately manufactured, and a continuous or discontinuous projection having a predetermined size is formed on a mounting surface of the binding tool. Are formed, and a resin file is welded in a state where the protrusion of the binding tool is brought into contact with the resin file surface material. Japanese Utility Model Laid-Open Publication No. 3-47178 discloses a resin file having a structure in which a fixing tool is formed of a polypropylene resin molded product, and the fixing tool is fixed to the back of the cover with eyelets or the like.

[0004] In such a resin file, a spine cover is provided on a back portion such as a back wall or a back portion. This spine cover is for protecting titles and the like described on the backing portion, and is usually formed of a film.

[0005]

However, since the spine cover made of film has poor rigidity, the effect of reinforcing the file by attaching the spine cover cannot be expected. Also, since the spine cover is a film, the spine portion can be formed only flat, and only a file having a uniform shape can be obtained.

An object of the present invention is to provide a resin file which can increase the degree of freedom in shape and improve rigidity.

[0007]

A resin file according to the present invention is a resin file having a file main body having a pair of front mounting portions connected to each other with a back mounting portion interposed therebetween. Is equipped with a spine cover made of resin injection-molded product, and this spine cover is composed of a plurality of resin parts, and these plural resin parts are detachable from the backing part It is characterized by being attached to.

In the present invention, since the spine cover is made of a resin injection-molded article, a spine cover with high rigidity can be obtained. Therefore, the rigidity of the file body can be simplified by mounting the spine cover on the spine portion. Can be improved. Further, since the spine cover can be formed three-dimensionally, the degree of freedom of the shape can be increased. Therefore, the variation of the shape of the resin file can be abundant, and various functions are provided on the spine cover, for example, the classification of the file, the notation of the contents, etc. are written on the entire spine cover or the resin parts constituting the spine cover. It can also have a function as a display board.

In addition, since the spine cover is composed of a plurality of detachable resin parts, it is necessary to change the contents of the spine cover, for example, by changing the file classification or contents. Even in such a case, it is possible to easily cope with the change of the description contents only by replacing the resin part of the part to be changed without replacing the entire spine cover. Moreover, since the resin parts are detachable, they can be easily replaced and used repeatedly. Further, it is not necessary to discard all the spine covers, thereby reducing waste.

In this case, as a detachable structure, a claw portion for attaching and detaching to the backing portion is provided on the resin part, and an engaging hole for engaging the claw portion is provided on the backing portion. Is considered. By doing so, the claw portion of the resin part and the engaging hole of the backing portion are firmly engaged with each other, so that it can be securely fixed, and the resin part can be securely attached with a slight impact. Can be prevented from coming off.

Further, it is preferable that the spine cover has transparency. According to this, when a title or the like is directly written on the spine portion, or when paper is interposed between the spine portion and the spine cover, When a title or the like is described, excellent visibility is obtained.

[0012] The spine cover may be provided with an engaging portion for hanging a finger. By providing such a locking portion, when pulling out a file stored in a shelf or the like, it is possible to easily pull out the file by hanging a finger on the locking portion. In this case, the locking portion may be a pocket provided between the spine cover and the backing portion. In this way, the file can be easily pulled out simply by inserting a finger into the pocket and moving it toward the front, that is, toward the spine cover side, and requires less space than providing a separate pocket on the surface of the spine cover.

At this time, the pocket may be constituted by a gap between a hollow convex portion provided on the spine cover and the backing portion. In this manner, by providing the convex portion on the spine cover and forming the pocket including the space in the convex portion, the pocket can be formed widely, so that the finger can be easily inserted into and removed from the pocket. Therefore, by putting a finger on the pocket, it is possible to easily pull out the resin file leaned against the shelf without any gap.

[0014] The pocket is preferably open toward an exposed portion that is not covered by the spine cover of the back portion. That is, when the pocket is open on the surface of the spine cover, the finger must be bent and inserted into the pocket, but in the present invention, the pocket is placed on the backrest toward the exposed portion of the backrest. Because it is open along, you can insert your finger into the pocket simply by moving your finger along the back part from the exposed part of the back part,
File extraction work can be facilitated.

In this case, the vertical size of the spine cover may be shorter than the vertical size of the backing portion, and the pocket may be opened toward the exposed vertical end of the backing portion. This eliminates the need to provide a special structure on the spine cover to expose the spine portion, thereby simplifying the structure of the spine cover.

[0016] In the above, it is preferable that a hand-holding portion for hanging a hand is provided at the end of the front-mounting portion on the side of the backing portion. By providing such a handle portion, when taking out a file from a shelf or the like, it is possible to easily pull out the file by hanging the handle portion.

Further, it is preferable that ends of the pair of front mounting portions opposite to the back mounting portion are inclined in directions approaching each other. According to this, when storing a file on a shelf or the like, if the file is pushed in by inserting it from the end on the inclined side, even if the space is small, the file can be pushed in easily and smoothly, and the front cover when pushed in It can prevent the part from turning over.

[0018]

Also,
The number of claws and engagement holes is arbitrary, and may be increased or decreased as needed. Further, a structure in which the return of the claw portion and the depression of the engagement hole are not particularly provided may be employed. However, it is preferable to provide them, since the resin parts can be securely attached to the backing part. Also in the first embodiment, similarly to the above-described embodiments, a pocket may be provided in the spine cover, and a handhold portion may be provided at an end of the front mounting portion on the side of the back mounting portion. Good.

In the second and fourth embodiments, the handle 6
5 is provided with a concave portion, and in the third embodiment, the handhold portion 75 is provided with a protrusion. However, the present invention is not limited to these, and for example, both the concave portion and the protrusion may be provided in the handhold portion. Further, the handle portion may be omitted. In the second to fourth embodiments, the pockets 63, 74, 8
Although 2 is provided at the lower end in the vertical direction of the backing portion 11A, it may be provided at the upper end in the vertical direction, or may be provided at an intermediate portion in the vertical direction. Further, the front cover portions 12A and 12B of the first, second, and third embodiments are respectively provided with the front cover portions 12 of the fourth embodiment.
It may be inclined similarly to A and 12B.

In each of the above-described embodiments, the front mounting portions 12A, 12A
Although B has been described as a plane file, a box-shaped file may be formed as a shape in which the periphery of the front mounting portion is raised. The shape is not limited to a rectangular shape, but is arbitrary. In each embodiment, the main holding portion 21 and the sub-holding portion 25 of the binding tool 20 are integrally formed with the file main body 10. However, the binding format of the file is not particularly limited. The present invention can also be applied to existing various resin files in which the unit and the sub-holding unit are separate members from the file body. Furthermore, spine covers 40, 60, 70,
The shape of 80 is not limited to those of the above embodiments as long as the requirements of the present invention are satisfied, and is arbitrary as long as it can be formed by injection molding.

[0053]

As described above, according to the present invention,
In a resin file having a file body in which a pair of front parts are continuously provided with a back part interposed therebetween, by attaching a spine cover made of a resin injection molded product to the back part, the rigidity of the file body is reduced. Can be easily improved. Also,
Since the spine cover can be formed three-dimensionally, the degree of freedom of the shape can be increased, and the variety of resin files can be increased.

Further, since the spine cover is composed of a plurality of detachable resin parts, it is necessary to change the contents of the spine cover, for example, by changing the file classification or contents. Even in such a case, it is possible to easily cope with the change of the description contents only by replacing the resin part of the part to be changed without replacing the entire spine cover. Moreover, since the resin parts are detachable, they can be easily replaced and used repeatedly. Further, it is not necessary to discard all the spine covers, thereby reducing waste.
