Description

  The present invention relates to a folder for storing an object to be held such as a document between a front plate portion and a back plate portion. In particular, the present invention relates to a folder whose form can be changed according to the amount of documents to be held.

Conventionally, as shown in FIG. 8, a flat plate such as cardboard is folded in half to make a V plate composed of a front plate portion (20) and a back plate portion (10) connected at the lower edge. A letter-shaped folder is used.
In this example, a heading portion (3) is formed to protrude from the upper edge (12) of the back plate portion (10), and the object to be held such as a document is transferred to the front plate portion (20) and the back plate portion. (10) can be searched by item by stacking folders in the front and back direction and storing them in a filing cabinet (8) or bookcase as shown in Fig. 9 It can be saved.

The folder has a structure in which the front plate portion (20) and the back plate portion (10) are continuous through the fold line (6). As in (A) and (D) in FIG. 9, the document or the like can be held while being sandwiched between the front plate portion (20) and the back plate portion (10). However, when there are a large amount of documents (5), as shown in (B), (C), and (E) in FIG. 9, the front plate portion (20) in the vicinity of the fold portion (6) serves as the bottom plate portion. Since it will be used, the height of the upper edge (22) of the front plate portion (20) is reduced, and the height of the back plate portion (10) is disproportionate with the document to be held (5) Depending on the amount, the upper edge (22) may be lower than the document or the like.
Thus, when the folder stored in the file cabinet (8) or the like as shown in FIG. 9 is taken upward from the opening (80), the front plate (20) is buried in the document or the like (5). In some cases, adjacent folders may be taken out together, or documents that are missed may fall out of the folder.

In addition, since the held document is exposed above the upper edge (22) of the front plate part (20), the document is bent when inserting a hand between folders for taking out. There is also a problem of being damaged or damaged.
The present invention has been made in view of the above circumstances, and “the front plate portion includes a front plate portion and a back plate portion that are coupled to each other at the lower end edge, and the object to be held such as a piece of paper or a document is placed on the front plate portion. It is an object of the present invention to make it possible to smoothly take out a target folder from a file cabinet or the like in “a folder configured to be held between a front panel and a back plate”.

(1) The folder of the device according to claim 1 includes: a front plate member including the front plate portion and a pocket portion that opens along a lower edge of the front plate portion;
The back plate member is composed of a back plate member that includes an insertion portion that extends from a lower end edge of the back plate portion and is inserted into and retracted into a pocket portion of the front plate member.
The front plate portion and the back plate portion are connected by inserting the insertion portion of the back plate member into the pocket portion of the front plate member ”.
According to this, since all the insertion portions of the back plate member are inserted into the pocket portions of the front plate member, the front plate portion and the back plate portion are connected with their lower end edges close to each other. Documents can be held in a letter-like manner like folders. A folder in a U shape in which the front plate portion and the back plate portion are connected by an insertion portion functioning as a bottom plate portion by appropriately pulling out the insertion portion from the pocket portion in accordance with an increase in documents to be held. The form can be modified.
Thus, unlike the conventional example, the height of the upper edge of the front plate portion does not gradually decrease corresponding to the increase in documents to be held, and the upper edge of the front plate portion and the back plate portion The upper edge can be kept at the same height.

(2) The folder of the invention according to claim 2 is characterized in that “the back plate portion of the back plate member has a plate width that cannot be inserted into the pocket portion of the front plate member”.
According to this, since the back plate portion connected to the insertion portion is not inserted into the pocket portion due to excessive insertion of the insertion portion, the height of the upper edge of the back plate portion is It is also possible to prevent lowering.

(3) The folder of the invention according to claim 3 is characterized in that a crease line parallel to a lower end edge of the back plate portion is formed at a predetermined interval in the insertion portion.
According to this, the insertion part can be pulled out from the pocket part along the crease line by bending the insertion part along the crease line.

(4) The folder of the invention according to claim 4 is characterized in that “the pocket portion of the front plate member is formed in a lower portion of the front plate portion”.
According to this, by forming the pocket portion (attaching an auxiliary plate portion, a bag portion, or the like), a portion having a multilayer structure is limited to a lower portion of the front plate portion, so that the upper side of the front plate portion The portion can have a single layer structure. Therefore, similarly to a conventional folder made of a single plate, a heading portion and a cut binding hole for binding documents can be formed in the upper portion.

(5) The folder of the invention according to claim 5 is: “The front plate member or the back plate member is provided with a drop prevention means for preventing the insertion portion inserted into the pocket portion from falling off. It is characterized by that.
According to this, it is possible to prevent the insertion portion from being easily pulled out or dropped due to swinging of a document held in the folder or the weight of the back plate member.
Here, the escape prevention means does not prevent a user from inserting and withdrawing the insertion portion into the pocket portion. Moreover, even if provided only in any one of the said front-plate member and a backplate member, it may be provided in both the said front-plate member and backplate member.

(6) The folder of the invention according to claim 6 is: “The drop-off prevention means includes a front plate folding portion that extends from a lower end edge of the front plate portion and is folded inside the pocket portion; It is composed of a back plate folding portion that extends to the free edge and is folded inside the pocket portion so as to be able to engage with the front plate folding portion.
According to this, the front plate member and the back plate member are erroneously separated because the engagement between the front plate folding portion and the back plate folding portion prevents the user from excessively pulling out the insertion portion. Can be prevented.
Moreover, since the said front board folding part and the back board folding part are the structures extended in the edge of the said front board part and the said insertion part, respectively, compared with what attaches the said drop-off prevention means which consists of another member. The structure is simple.

(7) The front plate member of the invention according to claim 7 is composed of a front plate portion and a back plate portion that are coupled in a superposed state at a lower end edge, and the object to be held such as a piece of paper or a document is A front plate member used for a folder configured to be held between the front plate portion and the back plate portion, wherein the front plate portion, a pocket portion that opens along a lower end edge of the front plate portion, and the pocket portion. It comprises a drop-off prevention means for preventing the plate member inserted freely from falling off.
The front plate member of the present invention can be used not only for the folder of claims 1 to 6 described above, but also by inserting the front plate portion of a conventional V-shaped folder as the plate member into the pocket portion. As shown in FIG. 9, a new front plate in which the top plate member of the present invention has the same height as the upper edge of the back plate portion instead of the conventional front plate portion of the folder used as the bottom plate portion in accordance with the increase in documents and the like. It can function as a part.
Thereby, the conventional V-shaped folder can be transformed into a U-shaped folder having a bottom plate corresponding to the thickness of a document or the like.

As described above, according to the device of the first aspect, the front plate member including the front plate portion and the pocket portion that opens along the lower end edge of the front plate portion, the back plate portion, and the back plate portion. By connecting a back plate member that is extended from the lower end edge and is inserted into the pocket portion so as to be freely inserted into and removed from the pocket portion, the drawing length of the insertion portion is adjusted to adjust the length of the object to be held. Since the folder shape can be changed from a V shape to a U shape depending on the amount, the upper edge of the front plate portion and the upper edge of the back plate portion are set to the same height regardless of the amount of the object to be held such as the document. Can be maintained.
As a result, it is possible to remove the target folder from the opening of the file cabinet or the like without taking out the adjacent folders together as in the conventional example or dropping the object to be held from the folder because the front plate part cannot be gripped. The folder can be taken out smoothly.

  In addition, since the objects to be held such as documents are held between the front plate part and the back plate part and are not exposed to the outside of the folder, the document etc. may be bent or damaged when the folder is taken out. There is nothing, and the preservation state of the objects to be held such as documents is excellent. Furthermore, the formation of the pocket portion improves the strength and durability of the folder because part or all of the front plate portion has a double structure.

According to the second aspect of the invention, since the back plate portion has a plate width that cannot be inserted into the pocket portion, it is possible to prevent the height of the upper edge of the back plate portion from being lowered. And the shift | offset | difference of the height position of the upper end edge of a backplate part can be eliminated.
According to the third aspect of the present invention, since the insertion portion can be evenly pulled out from the pocket portion by forming the crease line in the insertion portion, the form of the U-shaped folder is stabilized.

According to the invention according to claim 4, since the pocket portion is formed in the lower portion of the front plate portion, the head portion and the binding hole can be formed in the upper portion of the front plate portion. Wide variation.
According to the fifth aspect of the present invention, by providing the drop prevention means for preventing the insertion portion from falling off, it is possible to prevent the insertion portion from falling off due to swinging of the object to be held or the weight of the back plate member. The front plate member and the back plate member are hardly separated from each other against the user's intention.

  According to the invention according to claim 6, the front plate folding portion is constituted by a fall prevention means comprising a front plate folding portion extending to the front plate portion and a back plate folding portion extending to the insertion portion. Since the user can prevent the front plate member and the back plate member from being accidentally separated by the engagement between the front plate member and the back plate folding portion, there is a disadvantage that the documents held by the separation are separated. Hard to happen. In addition, since the structure is simpler than that provided with the drop prevention means made of another member, the manufacturing is easy and the manufacturing cost is low.

  According to the invention according to claim 7, a conventional V-shaped folder is replaced with a U-shaped folder by inserting the front plate portion of a V-shaped folder made of a single plate into the pocket portion of the front plate member. Therefore, by attaching the front plate member of the present invention to the folder in use, the target folder can be smoothly taken out from the file cabinet or the like as in the first aspect. .
