technical field

The present invention relates to a binder body used when binding documents and other papers into folders, and a file folder provided with the binder body which can adjust the width of the back cover, and which has the ability to adjust the width of the back cover according to the increase or decrease of papers and is used A folder with an adjustable back cover for the binding foot of the folder.

Background technique

Conventionally known is a folder in which the paper is bound by penetrating a binding foot through a binding hole formed on the paper. Among them, there are various proposals, such as file folders in which the width of the back cover can be changed to match the amount of paper to be bound. A folder that changes the width of the back cover is, for example, a front and back cover that are separated from each other, and a back cover of any width is integrated on one side of the front cover, and the back cover is formed in such a way that one side is formed into a bag shape with an opening . Then, papers are sandwiched with the side edge of the back cover inserted into the opening of the back cover. Because of this structure, the width of the exposed back cover varies depending on the amount of the back cover inserted into the back cover, and the amount of bound papers can be freely changed.

In addition, binding leaflets for holding the paper sheets are provided on the front and back covers, and through holes are provided in the binding leaflets at positions approximately equal to the binding holes formed on the paper sheets. In addition, in such a folder, the binding foot is inserted through the through hole of the binding leaf provided on the back cover to sandwich the papers, and then the binding foot is engaged with the binding body on the side of the binding leaf provided on the front cover to bind the paper. class form.

It is necessary for the binding foot used for the folder whose width of the back cover is changed to have a length sufficient to cope with the increase in the number of papers to be bound. If the binding legs are extended in advance in order to sandwich more papers, the binding legs will be exposed from the cover when there are few papers to be sandwiched, resulting in a problem that it looks ugly and is inconvenient for storage.

As a folder whose length of binding feet can be adjusted according to the amount of papers to be bound, for example, as disclosed in Patent Publication No. 3095690, it has a folder that is connected as a whole when the amount of papers is increased. A pair of binding feet divides it into two, resulting in an extended binding foot. In addition, as disclosed in (Japanese Patent) Unexamined Patent Publication No. 2006-95964, on the binding binder that is connected to one side of the paper, an installation hole through which the binding foot can penetrate and an elastically deformable folder are formed. There is a holding part, and the length of the binding leg is adjusted according to the amount of paper by removing the excess length of the binding leg from the holding part.

In addition, in order to maintain the stability of the overall shape of the folder whose back cover width is changed, even when the amount of paper increases, when fixing the binding legs, the front cover, back cover, binder body, and binding legs are integrated to stabilize the binding. The tool body is fixed on the cover. When fixing the binder body to the cover, since fixing parts such as rivets are used, it is difficult to sort when discarding.

In this case, as an invention that considers sorting and discarding, for example, the folder disclosed in (Japanese Patent) Japanese Patent Application Laid-Open No. 2003-320778 is a binder body that will be installed on a binder for binding. It consists of a base formed through the opening of the binding foot, and a slide block that can slide on the base and can open and close the opening accordingly. Simultaneously, make the position of the opening side of the opening of this base protrude more than this base and the splicing surface of the binding leaflet, and in the state where this protrusion is inserted into the through hole of the binding leaflet, it will also be on the base. The engaging claws provided on the splicing surface of the base are engaged with the engaging holes of the bound binder, so that the base is fixed on the bound binder.

Contents of the invention

As shown in Figure 4, under the condition that the binder body 8 is installed on the binding leaflet 4 of the cover 1, and the binding feet 9 are installed on the binding leaflet 6 of the back cover 2, the joint is set on the back cover 2. The side end portion of the back cover 3 is inserted into the back cover insertion portion 10 of the cover 1 . At this time, the folded piece 5 of the cover 1 is folded into the back cover insertion portion 10 of the cover 1 as shown in FIG. 5 . Folding the folding piece 5 into the back cover insertion portion 10, the falling-off preventing portion 7 connected to the back cover 3 is locked on the folding piece 5, preventing the back cover 3 from falling off the cover 1 inadvertently. And, the binder body 8 makes the operating portion 31 stand up, so that the notch 43 of the binder body 8 and the through notch 13 of the binding leaflet 4 of the cover 1 are in a state of being able to penetrate each other.

Next, the two binding script bodies 61 pulled out from the main installation holes 23 of the binding leaflet 6 of the back cover 2 are penetrated to the penetration gap 13 of the binding leaflet 4 of the front cover 1 along one side of the gap. Thereafter, the operation portion 31 of the binder body 8 is pushed down, and the first binding leg pressing portion 34 and the second binding leg pressing portion 35 are slid outward. In this way, the binding script body 61 is fitted in the notch 39 of the first binding foot pressing part 34 and the second binding foot pressing part 35 and bends outwards, and the groove 66 formed on the top of the binding script body 61 is aligned with the base. The locking protrusion 46 provided on the upper surface of the seat substrate 42 engages with it. When the operation part 31 is fully depressed, the binding script body 61 is locked with its front end facing outward.

In the present invention, when the folder in use has more papers to be bound, the position of the binding hole locked by the locking portion 62 of the binding foot 9 can be moved to make a response. That is to say, as shown in FIG. 11 , the locking portion 62 is locked on the second mounting hole 22, so that the binding script body 61 main body extracted from the main mounting hole 23 of the binding leaflet 6 can be just extended. is the length of the first mounting hole 21 and the second mounting hole 22 .

As a method of moving the locking portion 62 of the binding foot 9 from the first mounting hole 21 to the second mounting hole 22, at first, lift the center of the operating portion 31 of the binding tool body 8, and make the first binding foot pressing portion 34 and the second mounting hole 22 move. 2. The binding foot pressing part 35 relatively moves inside, and the locking of the binding foot body 61 is released. Next, the locking portion 62 exposed on the side not in contact with the sheets of the binding leaflet 6 of the back cover 2 is slightly pulled out. Then, the front end portion of the locking blade 64 is fitted into the first mounting hole 21 while sandwiching and pressing the locking blade 64 of the locking portion 62 from both sides. Then, one pulls the front end of the binding script body 61, and the locking part 62 then passes through the first mounting hole 21 to move to the side that is in contact with the papers of the binder 6, and the base of the binding script body 61 is locked on the second side. Mounting hole 22.

In this way, the length of the binding script body 61 pulled out from the main mounting hole 23 becomes longer, thereby increasing the number of papers that can be sandwiched, and pulling out the cover back 3 in response to the thickness of the papers so that the cover can be adjusted freely. The magnitude of the back 3. The operation of changing the length of the drawn-out binding script body 61 and pulling out the back cover 3 from the cover 1 can be easily performed in a state where the paper sheets are bound in the folder.

In the present invention, after the sheets P are bound with the binder, the sheets P can be re-bound with the binding thread B, and the binder body 8 and the binding feet 9 attached to the folder can be detached. When the amount of papers to be bound is fixed, the papers P are bound with the binding thread B instead of the binder, so that the detached binder body 8 and binding feet 9 can be reused on other folders. Simultaneously, reducing the thickness of the binder body 8 can make the places for keeping folders less.

As a method of binding papers P by the binding line B, first stand up the operation part 31 of the binding tool body 8, release the locking of the binding script body 61, and pinch and lock it on the back cover as shown in Figure 12 (a). The locking portion 62 of one of the binding legs 9 on the first mounting hole 21 of the binding leaf 6 of 2 is pulled out to the outside of the binding leg 9 . Next, the leading end of the binding B is inserted into the main mounting hole 23 and pulled out from the binding leaf 4 side of the cover 1 . Then, as shown in Figure 12 (b), similarly, the other side's binding foot 9 is also extracted, and the other end of the binding wire B is inserted into the main installation hole 23, and from the side of the binder 4 of the cover 1 pull it out.

Next, not shown in the figure, remove the binder body 8 installed on the binding leaflet 4 of the front cover 1, as shown in Figure 13 (a), put the paper P and the binding leaflet 6 of the back cover 2 Hold the back cover 3 with one hand and pull out the folded piece 5 provided at the base of the binding leaflet 4 of the cover 1 inserted into the back cover insertion portion 10 of the cover 1 . Then, as shown in FIG. 13( b ), the drawn folded sheet 5 is erected so as to be in contact with the binding leaf 4 .

Then, as shown in FIG. 14( a ), in a state where the folded pieces 5 are erected, the leading ends of the bindings B are inserted into the third through holes 14 of the corresponding folded pieces 5 . Then, as shown in Fig. 14(b), the back cover 3 is inserted into the opening of the cover 1 again, and the width of the back cover 3 is adjusted to be the same as the thickness of the paper P, so that the bound leaflet 4 of the cover 1 is aligned with the paper. The class P joins to connect the two ends of the gutter B.

According to the above operation, after binding with the binding tool, the papers P are bound again by the binding thread B, and the binding tool body 8 and the binding foot 9 can be replaced and used on other file folders.

As another aspect of the present invention, as shown in FIG. 15 , the first binding hole 21 may be arranged as two first mounting holes 21 . For example, as shown in Figure 15 (a), the second mounting hole 22 and the main mounting hole 23 are symmetrically formed on each outer side of the two first mounting holes 21, and the binding foot 9 is inserted from the first mounting hole 21, and passes through the second mounting hole 21. The installation hole 22 and the main installation hole 23 lock the locking portion 62 on the first installation hole 21 . Also, as shown in FIG. 15(b), the two first mounting holes are arranged on the outside, and the second mounting hole 22 and the main mounting hole 23 are symmetrically formed inside the first mounting hole. Then, insert the binding leg 9 from the first installation hole 21 , pass through the second installation hole 22 and the main installation hole 23 , and lock the locking portion 62 on the first installation hole 21 . In any case, the positions of the two binding holes provided on the paper P and the main installation hole 23 should be consistent. On the installation hole of configuration like this, the length of binding foot body is installed than from the 1st installation hole 21 to the 2nd installation hole 22, and the length of the file folder end portion of main installation hole 23 sides slightly shorter binding foot 9 is installed, by This makes it possible to be a folder capable of coping with an increase or decrease in the amount of sheets P.
