Description

Folder binding body and folder for adjustable side cover width

The present invention relates to a binding body for use when ordering paper sheets such as materials into a folder, and a folder having an adjustable side cover width of the binding body, and for increasing or decreasing the paper type. Adjust the side cover width and make a folder for the adjustable side cover width of the folder clip.

It is a well-known type of folder that inserts a clip through a pinch hole formed in a sheet to bind the embodiment of the sheet. There are also various proposals, such as changing the width of the side cover to correspond to the folder of the amount of paper to be ordered. A folder that can change the width of the side cover, for example, the cover and the back cover are separated from each other, and the side cover of any width is integrated on one side of the cover, and the structure of the back cover is formed into a bag with an opening on one side. . The paper sheet is sandwiched in a state in which the side edge portion of the side cover is inserted into the opening of the back cover. With this configuration, the extent of the exposed side cover changes depending on the amount of the side cover inserted into the back cover, and the amount of the bound sheets can be freely changed.

Further, a binding flap for holding the sheet is provided on the front cover and the back cover, and a through hole is formed in the binding flap at a position substantially equal to the binding hole formed in the sheet. Further, such a folder is inserted into the sheet from the through hole of the binding flap provided on the back cover to sandwich the sheet, and then the binding member is used to lock the clip on the side of the binding flap provided on the cover. Thus, the form of the paper sheet is bound.

The clips used on the folder for changing the side cover width need to have a sufficient length corresponding to the increase in the number of sheets to be ordered. In the case where the folder is stretched in advance in order to sandwich more sheets, when the sheet to be jammed is small, the clip is exposed from the cover, which causes a problem that looks unattractive and inconvenient to store.

A folder that can adjust the length of the clips corresponding to the amount of sheets to be bound, as disclosed in Patent Document 1, for example, when the amount of paper sheets is increased, by connecting the sheets in one piece The pair of jaws are cut to divide them into two, thereby extending the jaws. In addition, as for the folder disclosed in Patent Document 2, the binding flap that is in contact with one side of the sheet of paper forms a mounting hole through which the clip member can pass and an elastically deformable holding portion. The holding portion peels off the remaining length of the jaw member to adjust the length of the jaw member corresponding to the amount of the sheet.

Then, in order to change the folder of the width of the side cover, in order to maintain the stability of the overall shape even when the amount of the paper sheet is increased, the cover, the back cover, the binding body, and the clamping member are integrally formed when the clamping member is fixed. Securely attach the binding body to the cover. When the binding body is fixed to the cover, it is difficult to classify it when it is discarded because fixed parts such as rivets are used.

In this case, in consideration of the classification and discarding, for example, the folder disclosed in Patent Document 3, which is to be mounted on the binding body of the binding folding plate, is formed by partially forming the through-clamping member. A base of the opening and a slider slidable on the base and capable of opening and closing the opening. At the same time, the portion of the opening edge which becomes the opening of the pedestal is protruded more than the splicing surface of the susceptor and the binding flap, and the protruding portion is inserted into the through hole of the binding flap. Similarly, the engaging claws provided on the joint surface of the base are engaged with the engaging holes of the binding flaps, so that the base is fixed to the binding flap.

As described above, in the state in which the integrally formed jaws are cut, since the connection piece cannot be reattached once the connection piece is cut, when the amount of the sheet is reduced, the front end of the folder is exposed from the folder. Not suitable. In addition, if the remaining length of the clamp member is detached from the holding portion for adjustment, the adjustment of the remaining long portion is complicated, and there is a problem that it takes time and effort to fall off.

Further, the folder that is engaged with the binding flap by providing the protruding portion and the engaging claw on the base of the binding body is easy to classify and can be effectively utilized even when the folder itself is discarded after use, even if In use, if the binding body is detached from the cover or the binding body is damaged, the paper sheet can only be re-bound into the new folder. At the same time, when the amount of paper sheets is increased, it is relatively troublesome to insert the jaws into the opening provided on the base portion of the body of the binding device. Further, in order to store a folder in which a certain amount of paper sheets are to be stored, the number of folders increases, and there is a problem that the storage space is wasted only due to the thickness of the binding body.
