(Preferred embodiment)
First, the overall configuration of the binding device 10 of the present invention will be described with reference to FIGS. 1 and 2. The binding tool 10 includes a stretchable binding cord 20, a rod-shaped first stopper 31 attached to the first end of the binding cord 20, and a rod-shaped first attachment attached to the second end of the binding cord 20. A second mounting member 41, a rear mounting plate 41 provided with a first mounting hole 41a through which the first mounting member 31 is inserted, and a second through hole 41b through which the second mounting member 32 is mounted, and a first mounting structure. The front attachment plate 42 is provided with a first through hole 42a through which the 31 is inserted and a second through hole 42b through which the second stopper 32 is inserted.

The binding string 20 is a long string made of a stretchable material. The binding string 20 may be made of any material as long as it has elasticity. Further, the material itself does not matter as long as it has elasticity. The binding string 20 may have a structure having elasticity only in a part of the entire length.

As shown in FIG. 3, the first stopper 31 and the second stopper 32 are rod-shaped (here, cylindrical or cylindrical) members arranged at both ends of the binding string 20. As will be described later, it is preferable that the back mounting plate 41 and the front mounting plate 42 have substantially the same outer diameter as the through holes 41a, 41b, 42a, 42b.

Further, slits 31a and 32a, which continuously extend from one end surface and into which the binding string 20 can be inserted and moved, are formed on the side surfaces of the rod-shaped first stopper 31 and the rod-shaped second stopper 32. There is. As shown in FIG. 6, the stoppers 31 and 32 can of course be formed in a simple columnar or cylindrical shape without slits.

As shown in FIG. 4, the rear mounting plate 41 is a rectangular plate-shaped member having a long dimension in the longitudinal direction. The rear mounting plate 41 has a plurality of (here, three) first through holes 41a,... On both sides of the center, and a plurality (here, three) of second through holes 41b,. , Are formed. The through holes 41a,..., 41b,... Are provided so as to correspond to the positions of the six holes of the bible-size sheet, for example.

As shown in FIG. 5, the front mounting plate 42 is a rectangular plate-shaped member having a long dimension in the hand direction. The front mounting plate 42 has a plurality (here, three) of first through holes 42a,... And a plurality (here, three) of second through holes 42b,... , Are formed. The through holes 42a,..., 42b,... Are provided so as to correspond to, for example, the positions of the six holes of the bible-size paper.

Further, a concave portion 42c into which the binding cord 20 can be fitted is formed on the end surface of the front attachment plate 42.

(effect)
Next, the effects of the binding device 10 of the present embodiment will be listed and described.

(1) As described above, the binding device 10 according to the present embodiment includes the elastic binding string 20, the rod-shaped first stopper 31 attached to the first end of the binding string 20, and the binding string. The rod-shaped second stopper 32 attached to the second end of 20, the first through hole 41a through which the first stopper 31 is inserted, and the second through hole 41b through which the second stopper 32 is inserted are A rear mounting plate 41 provided and a front mounting plate 42 provided with a first through hole 42a through which the first stopper 31 is inserted and a second through hole 42b through which the second stopper 32 is inserted. I have it. With such a configuration, the writable area of the bound element such as paper is wide. That is, since the elastic binding strap 20 can be opened and closed 180 degrees, it is possible to write in all areas other than the binding strap 20.

(2) Further, the rear mounting plate 41 is provided with a plurality of first through holes 41a,... And a plurality of second through holes 41b,. By providing the first through-holes 42a,... And the plurality of second through-holes 42b,.. By selecting, the optimum binding force can be obtained.

(3) Further, since the slits 31a and 32a into which the binding cord can be inserted and moved are formed on the side surfaces of the rod-shaped first stopper 31 and the rod-shaped second stopper 32, the front mounting plate 42 is formed. The first stopper 31 and the second stopper 32 can be securely and easily hooked on the front side of the.

(4) Further, since the recess 42c into which the binding cord 20 can be fitted is formed on the end surface of the front attachment plate 42, the thickness of the entire binding tool 10 can be further reduced.

(Others) In addition to the effects described above, according to the binding device 10 of the present embodiment, it is possible to provide the binding device 10 for files that are easily bound. That is, by using the rod-shaped stoppers 31 and 32 made of resin, the stoppers 31 and 32 can be passed through the holes of the element to be bound, such as paper, without being bent, and can be easily bound.

Further, according to the binding tool 10 of the present embodiment, the binding tool 10 that does not easily shake the paper is obtained. That is, the elastic binding string 20 allows the front attachment plate 42 and the rear attachment plate 41 to be evenly sandwiched, and the binding string 20 itself is distorted, so that the holes provided in the element to be bound (for example, paper) The load on the binding target is reduced, and the bound element (for example, paper) is in a binding state in which it is difficult to tear.

Furthermore, according to the binding tool 10 of the present embodiment, the binding tool 10 has a wide writable area in the element to be bound (for example, paper). That is, it is possible to open and close 180 degrees by the elastic binding cord 20, and it is possible to write in almost all areas other than the binding cord 20 near the binding tool 10.

Further, the binding tool 10 of the present embodiment is a binding tool 10 for a thin file. Specifically, since the thickness is “the front mounting plate 42+the back mounting plate 41+the two binding strings 20”, the overall thickness can be reduced.

(How to use the binding tool)
The binding tool 10 can be used as follows, for example.
(1) Pass the binding cord 20 through the rear mounting plate 41 like the filed member (for example, paper) and the front mounting plate 42. That is, the stoppers 31 and 32 are passed through the holes of the member to be filed (element to be bound). At this time, the stoppers 31 and 32 are inserted into the rear mounting plate 41 and the front mounting plate 42 so as to be upright, so that the member to be filed can be easily inserted.
(2) Stoppers 31 and 32 at both ends of the binding string 20 are stopped so as to be caught in the insertion holes 42a and 42b of the front mounting plate 42. Alternatively, the stoppers (pipes) 31 and 32 are passed through the recesses 42c of the front mounting plate 42 to stop them.
(3) When the number of sheets of paper is increased (decreased), the tension of the binding cord 20 is adjusted by selecting the through holes 41a, 41b, 42a, 42b through which the binding cord 20 is inserted according to the thickness.

The material of the rear mounting plate 41 is preferably resin (eg, nylon).
By making the diameters of the rear mounting plate 41 and the stoppers 31 and 32 equal, the stoppers 31 and 32 fit exactly into the insertion holes 42a and 42b, and the file can be easily taken in and out.

The material of the front mounting plate 42: resin (for example, nylon) is suitable.
The stoppers 31 and 32 can be moved to the upper side or the side surface of the file by increasing the outer diameter of the stoppers 31 and 32 of the binding cord 20 to form a groove through which only the binding cord 20 can pass. This will result in a thinner file.

Binding string 20: rubber (hair rubber) is suitable. However, any material that has elasticity can be used.
Stoppers 31, 32 of the binding string 20: Resin (for example, nylon) is suitable.
The binding string 20 and the stoppers 31 and 32 were prototyped. The binding string 20 can be made by cutting hair rubber into an appropriate length, for example. The stoppers 31 and 32 can be manufactured by, for example, a 3D printer.
Since the binding cord 20 does not protrude from the stoppers 31 and 32 when the holes of the file are passed, it is easy to pass.
When binding a file, the binding strings 20 of the stoppers 31 and 32 can be slid to the grooved side to be hooked on the front mounting plate 42 and firmly bound.

(How to assemble the prototype of the binding cord and the stopper)
The binding string 20 and the stoppers 31 and 32 can be assembled as follows, for example.
(1) Pass the fishing line in a loop through the stopper (pipe-shaped).
(2) Pass the hair rubber through the loop.
(3) Pull the fishing line and pass the hair elastic through the stopper.
(4) Tighten the hair rubber and cut off the excess hair rubber.
(5) Tighten the knot and pull the hair elastic so that it enters the stopper.
(6) Do the same for the other.
(Point) If the inner diameter of the fastener is manufactured so that the size of the hole of the hair elastic and the fastener fits tightly, the hair elastic portion of the binding string will not be completely slipped.

(Experiments on materials)
Next, the material of each member will be considered.

Rear mounting plate: Metal (stainless steel)
By using a material with high hardness, the main body became difficult to bend even if the binder was firmly bound with the binding string. However, it is not the best example because of its unsightly appearance and fear of leftover burr.

Front mounting plate: Metal (stainless steel)
By using a material with high hardness, the main body became difficult to bend even if the binder was firmly bound with the binding string. However, it is not the best example because of its unsightly appearance and fear of leftover burr.

Binding string: Resin (nylon = fishing line)
There is some growth so it can be used. It is not optimal because it is too thin and the paper is easy to tear. On the contrary, if it has such a purpose as a daily calendar, it may be a merit.

Binding string stopper: Metal (stainless steel)
By making a hole on one side of the round pipe, we made a fastener by passing a string of a binding string through the hole. The manufacturing method is by laser processing, and it was created by penetrating a laser from the center of the side of the round pipe to the end of the side. The reason why such a method is adopted is that it is difficult to make a light and small iron pipe by changing the inner diameter thereof. [Maximum length of cross-section view horizontal to binding cord axis] is [Pipe diameter + Binding cord string], which makes it difficult to pass the file through the file (though it passes), so it is an optimal example. do not do.

(Experiments on binding strings and fasteners)
Next, an experiment on the binding string and the stopper will be described.
A binding string was prototyped using a combination of a fastener created with a 3D printer and a ready-made string.

(Experiment 1)
Can you pass an elastic cord? (The result is ok or ng on the left side), and after passing it again, can you make a tight knot and pass the knot? (Right side result is ok or ng) was tested.

[Outer diameter: 4.5 mm, inner diameter: 3.5 mm] pipe vs rubber A_1 to rubber D
result:
-Rubber A_1 ok ok
-Rubber A_2 ok ok
-Rubber B ok ok
-Rubber C ok ok
-Rubber D ok ng
Rubber A_1 can pass through a pipe of [outer diameter: 4.5 mm, inner diameter: 3.5 mm] according to the method of [assembling the binding cord]. However, the knot after the solid knot of [Binding string assembly method] cannot be stored in the pipe.

[Outer diameter: 4.0 mm, inner diameter: 3.0 mm] pipe vs rubber A_1 to rubber D
result:
Rubber A_1 ok ok
Rubber A_2 ok ok
Rubber B ok ok
Rubber C ok ok
Rubber D ng-

[Outer diameter: 3.5 mm, inner diameter: 2.5 mm] pipe vs rubber A_1 to rubber D
result:
Rubber A_1 ok ok
Rubber A_2 ok ok
Rubber B ok ok
Rubber C ok ok
Rubber D ng-

[Outer diameter: 3.0 mm, inner diameter: 2.0 mm] pipe vs rubber A_1 to rubber D
result:
Rubber A_1 ng-
Rubber A_2 ng-
Rubber B ng-
Rubber C ng-
Rubber D ng-

Conclusion: It seems that it will not be able to pass between the inner diameter of 2.0 mm and 2.5 mm.

(Experiment 2)
It was tested whether it was firmly fixed in the part where the inner diameter was changed.
This test is done only on rubber A_1. (Though it is not impossible to use other rubber cords, rubber A_1 was selected as the most suitable example because it was thought that the thicker the paper, the more likely it would be torn.) In Experiment 1, the pipe thickness was set to 0.5 mm. However, it was fragile and I could crush it with my fingers. The thickness of the stopper was set to 0.75 mm.

result:
Outside diameter: 4.0 Inside diameter 1: 2.5 mm Inside diameter 2: 2.0 mm
ng It is easy to pass a string, but it will come off if you pull strongly.
Outer diameter: 4.0 Inner diameter 1: 2.5mm Inner diameter 2: 1.8mm
ok The string is still easy to pass through and cannot be pulled out even if you pull it hard.
Outer diameter: 4.0 Inner diameter 1: 2.5mm Inner diameter 2: 1.6mm
ok It takes a lot of force to pull the string through, but you can't pull it out even if you pull it hard.
Conclusion: If the inner diameter is 1.6 mm or 1.8 mm, the knot will not come off, which is good.

(Experiment on diameter of through hole of back plate and diameter of stopper)
The diameter of the 4.0mm diameter fastener made by the 3D printer was changed from 3.75mm to 4.00mm on the rear mounting plate made by the 3D printer (Background of the experiment: It is more convenient to fit so that the stopper stands upright when loading or removing the paper).
Hole diameter: 4.00mm
A maximum tilt of 9 degrees occurs. There is almost no resistance when passing it.
Hole diameter: 3.95mm
A maximum tilt of 5 degrees occurs. There is almost no resistance when passing it.
Hole diameter: 3.90mm
Inclination of up to 4 degrees occurs. There is a slight resistance when passing it.
Hole diameter: 3.85mm
A maximum tilt of 3 degrees occurs. There is a slight resistance when passing it.
Hole diameter: 3.80mm
Up to 1 degree tilt occurs. There is a slight resistance when passing it tightly.
Hole diameter: 3.75mm
A maximum tilt of 0 degrees occurs. There is a strong resistance when passing it tightly.
Therefore, if it is 3.80 mm to 3.85 mm, it is most suitable because the stopper is upright and there is not much resistance in passing the stopper.

(Refill for book cover)
As shown in FIGS. 7 and 8, a book cover refill 50 as a plate is attached to the rear mounting plate 41 and/or the front mounting plate 42 of the binding device 10 so that the book cover can be inserted into a book cover for use. it can.

The book cover refill 50 is designed so that the opening and closing of the file itself is not affected by the bent back portion. (If you just insert a hard refill for the cover into the book cover, the file itself will open at the same time when you open the book cover.) Also, if you make the material with resin, it can be used for various book covers. You can also cut it to fit and use it.

(Binding string only)
Next, with reference to FIGS. 9 and 10, a binding tool 10</b>A including only the binding cord 20 without the back mounting plate 41 and the front mounting plate 42 will be described.

First, the configuration of the binding tool 10A will be described. In the binding tool 10A, the binding string 20 having elasticity, the rod-shaped first stopper 31 attached to the first end of the binding string 20, and the binding string 20 are provided. It is composed of only a rod-shaped second stopper 32 attached to the second end. On the side surfaces of the first stopper 31 and the second stopper 32, slits 31a and 32a into which the binding cord 20 can be fitted and moved are formed.

Next, a method of assembling the binding tool 10A will be described. The method for assembling the binding tool 10A includes the following two steps.
1. Thread the binding string 20 through the hole in the file.
2. By bending the first stopper 31 and the second stopper 32 at substantially right angles to the binding string 20 and passing them through the slits 31a and 32a, the first stopper 31 and the second stopper 32 are attached so as to be caught by the file.

Next, the effect of the binding tool 10A will be described. As described above, the binding device 10A according to the present embodiment has the elastic binding string 20, the rod-shaped first stopper 31 attached to the first end of the binding string 20, and the second binding string 20. It is composed only of the rod-shaped second stopper 32 attached to the end portion. Then, slits 31a, 32a into which the binding cord 20 can be fitted and moved are formed on the side surfaces of the first stopper 31 and the second stopper 32.

With such a configuration, it is possible to combine a plurality of files (paper or the like) into one. Furthermore, it is possible to use multiple files as a notebook by putting them together. Further, by removing the binding tool 10A, a plurality of files can be separated again or the files can be put together again. When the binding string 20 is under tension, the file itself may be bent. Therefore, the tension can be adjusted by changing the position of the hole (the hole on the file side (paper side)) or the length of the string portion can be adjusted when the binding string 20 is created.

Other configurations, operations, and the like are the same as those in the embodiment 1-5, and thus the description thereof is omitted.

(Rear mounting plate and front mounting plate are integrated)
Next, with reference to FIGS. 11 and 12, the binding device 10B including the integral mounting plate 40 configured by integrally forming the rear mounting plate 41 and the front mounting plate 42 will be described.

First, the structure of the binding tool 10B will be described. The binding tool 10B is similar to the first embodiment in that the binding string 20, the first stopper 31, the second stopper 32, the rear mounting plate 41, and the front mounting And a plate 42. In the binding device 10B of the present embodiment, the rear mounting plate 41 and the front mounting plate 42 are connected by the semi-cylindrical connecting portion 43 to form the integral mounting plate 40.

Next, a method of assembling the binding tool 10B will be described. The method for assembling the binding tool 10B includes the following four steps.
1. 1. Pass the binding string 20 through the hole on the back side of the integrated mounting plate 40. Thread the binding string 20 through the file 3. 3. Pass the binding string 20 through the hole on the front side of the integrated mounting plate 40. The first stopper 31 and the second stopper 32 are bent at substantially right angles to the binding string 20 and passed through the slits 31a and 32a, so that the first stopper 31 and the second stopper 32 are attached to the integrated mounting plate 40 so as to be caught.

Next, the effect of the binding tool 10B will be described. As described above, the binding tool 10B of the present embodiment is an integral mounting in which the binding cord 20, the first stopper 31, the second stopper 32, the rear mounting plate 41, and the front mounting plate 42 are integrated. And a plate 40.

With such a configuration, the positions of the holes on the front side and the positions of the holes on the back side of the integrated mounting plate 40 are aligned at the corresponding positions. As a result, even when the binding string 20 is stretched relatively loosely, the file is less likely to be disturbed, and even when it is disturbed, the file can be easily arranged.

Other configurations, operations, and the like are the same as those in the embodiment 1-5, and thus the description thereof is omitted.

Although the embodiment of the present invention has been described in detail above with reference to the drawings, the specific configuration is not limited to this embodiment, and any design change that does not depart from the gist of the present invention is not limited to included.

For example, in Example 1-5, the binding tool including the binding string 20, the first stopper 31, the second stopper 32, the rear mounting plate 41, and the front mounting plate 42 has been described. Of these, the front mounting plate 42 is not an essential component and may be omitted.

That is, as a binding device of another form, a binding string having elasticity, a rod-shaped first stopper attached to the first end of the binding cord, and a rod-shaped attachment attached to the second end of the binding cord A second backing plate, and a back mounting plate provided with a first through hole into which the first stop is inserted and a second through hole into which the second stop is inserted, May be Even with such a configuration, the desired purpose of binding the bound element can be sufficiently achieved by suppressing the front surface of the bound element with the first stopper and the second stopper.

Further, as the material of the binding string 20, a wire that has a spring incorporated therein and can be expanded and contracted, or the spring itself (a long version of the spring that is contained in the core of a ballpoint pen) can be substituted. That is, the binding string 20 may be made of any material as long as it is a string (or a long member) that expands and contracts in the lengthwise direction.

It is also possible to separate the stop from the rod that is threaded through the file. By separating, the stopper part becomes simple and unnoticeable. However, since the rod itself cannot be removed from the string, it will remain on the string that passes through the rear mounting plate portion of the file.
