Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

As shown in FIGS. 1 to 5, the notebook N is formed by binding the

cover sheets

1 and 2 and the middle sheet 3, which are a plurality of sheets 6 having binding holes 61, with a ring 4. Specifically, the notebook N includes a front cover 1 and a back cover 2 made of a synthetic resin sheet or cardboard, and a plurality of writing sheets arranged between the front cover 1 and the back cover 2. A front cover 1, a front cover 2, a plurality of binding holes 61 formed at the base of the inner cover 3, and using the binding holes 61, the front cover 1, the back cover 2, and And a ring 4 for binding the inner paper 3. The binding holes 61 are normal ones having a rectangular shape, and a plurality of binding holes 61 are provided at a predetermined pitch. Here, FIG. 1 shows a state in which the last middle sheet 3 is opened, and FIG. 2 is an enlarged view showing a main part of FIG. FIG. 3 is an enlarged bottom view showing the main part of FIG.

As shown in FIGS. 1 to 3, the ring 4 connects a plurality of ring main bodies 41 inserted through the binding holes 61 and the base ends of the ring main bodies 41 to each other. The ring body 41 is made of a synthetic resin such as polypropylene having a connection portion 42 that holds the ring body 41 and maintains each ring body 41 in a closed ring shape, and the tip side of each ring body 41 and the connection portion 42 In the joining area | region 40, it joins by welding. The ring body 41 is made of a soft material having a thickness of about 0.2 mm, for example. The soft material is a material that can be elastically deformed temporarily when a user's hand touches the annular portion 43, but can self-return to the original curved shape when the external force is released. It is configured.

More specifically, as shown in FIGS. 1 to 3, the ring main body 41 is a bent portion for raising a part of the ring main body 41 with respect to the connecting portion 42 at a portion other than the joining region 40. 44, 45. A portion of the ring body 41 other than the joining region 40 has a second bent portion 45 spaced from the first bent portion 44 in the circumferential direction. That is, the ring body 41 includes an annular portion 43 having a base end integrally connected to the connecting portion 42, and a distal end portion that is provided continuously to the distal end of the annular portion 43 and is in close contact with and overlaps the connecting portion 42. 47. The ring 4 has a first bent portion 44 formed at the boundary between the annular portion 43 and the tip portion 47, and a second bent portion at a certain distance from the first bent portion 44. A portion 45 is formed. This fixed distance is determined according to the thickness dimension of the note N. The bent portion 44 is provided in the vicinity of the joining region 40.

The ring body 41 is designed based on the concept as shown in FIG. 5, and the length in the circumferential direction of the portion other than the joining region 40 is set to 26 mm, for example. That is, as shown in FIG. 5, the total thickness dimension of all sheets 6 to be bound, that is, the front cover 1, the back cover 2 and the middle sheet 3 is amm, the side edge 62 on the binding origin side of the paper 6 and the binding holes The shortest distance from the binding origin side edge 63 of 61 is bmm. At this time, the ring body 41 has a length in the circumferential direction of a portion other than the joining region 40 from 2π × √ {(0.5a) ² + b ² } to 2π × √ {(0.5a) ² + (B + 3.0 mm) ² }. In other words, the length in the circumferential direction of the portion other than the joining region 40 is a length dimension of a lateral band-like portion 51 to be described later in which a welding margin is left, and is an annular shape of the ring body 41 of the notebook N. The circumferential length of the portion, that is, the length of the annular portion 43. In the notebook N of the present embodiment, for example, the total thickness dimension of the front cover 1, the back cover 2 and the middle cover 3 is 5 mm, and the shortest distance between the side edge 62 on the binding source side of the paper 6 and the edge of the binding hole 61 is Since the distance is 2.3 mm, a = 5 and b = 2.3 are substituted into the above formula, and the ring body 41 has a circumferential length of 21 mm other than the joining region 40. It is set to 37 mm. The total thickness dimension of the front cover 1, the back cover 2, and the inner cover 3 is 5 mm, and the shortest distance between the side edge 62 on the binding origin side of the paper 6 and the edge of the binding hole 61 is 2.3 mm. In the case of the ring main body 41, the length in the circumferential direction of the portion other than the joining region 40 is preferably 25 mm to 28 mm.

On the other hand, the connecting portion 42 has a flat plate shape. As shown in FIGS. 1 to 3, the connecting portion 42 is positioned between the inner paper 3 and the back cover 2, so that the ring 4 The middle sheet 3 and the

cover sheets

1 and 2 are bound.

The ring 4 is formed by a ring forming member 5 as shown in FIG. The ring forming member 5 is made by punching a sheet material made of synthetic resin, and has a plurality of horizontal belt portions 51 corresponding to the ring body 41 and a vertical belt shape corresponding to the connecting portion 42. Part 52. That is, the plurality of horizontal belt portions 51 and the vertical belt portions 52 are integrally formed.

The ring-forming member 5 is passed through the binding hole 61 with the horizontal strip 51 in a state where a certain number of the middle sheets 3 and the

covers

1 and 2 are aligned, and the vertical ends are held by a jig (not shown). It winds up to the strip | belt-shaped part 52 side. Thereafter, the through ends of the horizontal strips 51 are joined to the vertical strips 52 by welding, whereby the ring 4 as shown in FIGS. 1 to 3 is formed.

As described above, the notebook N according to the present embodiment binds the front cover 1, the back cover 2, and the middle paper 3, which are a plurality of sheets 6 having a plurality of rectangular binding holes 61, with the ring 4. The ring 4 connects the plurality of ring main bodies 41 inserted through the binding holes 61 and the base ends of the ring main bodies 41 to each other, and connects the distal ends of the ring main bodies 41 to each other. And a connecting portion 42 that holds and maintains each ring body 41 in a closed ring shape, and the distal end side of each ring body 41 and the connecting portion 42 are welded in the joining region 40. Therefore, it is possible to provide a notebook N having a good feeling of use by eliminating the problems that occur in the case of a conventional ring made by deforming a metal wire.

More specifically, when the user uses the notebook N for the purpose of writing or the like, the ring 4 is exposed between the adjacent inner papers 3. The ring 4 is made of synthetic resin. For this reason, it is relatively soft compared to conventional metal rings, and the unpleasant feeling of biting into the user's hand is suppressed. In particular, in this embodiment, since a material that causes temporary elastic deformation when a user's hand touches the annular portion 43 of the ring main body 41 is used, the usability is good. Furthermore, since the annular portion 43 is in a band shape, a sense of incongruity when the user's hand hits is reduced compared to a conventional linear shape.

Further, the plurality of ring main bodies 41 are inserted corresponding to the plurality of binding holes 61, respectively, and in this embodiment, the dimensions of the vertical sides of the rectangular binding holes 61 are defined as the ring formation. Since the width of the horizontal band-like portion 51 of the member 5 is substantially matched, the annular portion 43 of the ring 4 corresponding to the horizontal belt-like portion 51 can be prevented from being displaced or deformed in the longitudinal direction side of the notebook N. .

Since the connecting portion 42 has a flat plate shape, the thickness of the notebook N can be relatively suppressed. Since the connecting portion 42 is positioned between the back cover 2 and the middle cover 3 adjacent to the back cover 2, when the notebook N is closed, the connection portion 42 is not applied from either the front cover 1 side or the back cover 2 side. Also, the connecting portion 42 is concealed. Also, when the notebook N is opened at a portion other than the back cover 2, the connecting portion 42 is not visible to the user. Therefore, when the notebook N is normally used, only the annular portion 43 of the ring 4 is exposed to the outside, so that an appearance similar to that of a conventional metal wire ring can be obtained.

Also, when the ring body 41 is joined to the connecting portion 42 by welding, the tip portion 47 of the synthetic resin ring body 41 is plastically deformed, so that the ring body 41 and the connecting portion 42 can be brought into close contact with each other.

Further, the ring 4 has a first bent portion 44 formed at the boundary between the annular portion 43 and the tip portion 47, and a second portion located at a certain distance from the first bent portion 44. As shown in FIG. 3, the binding holes 61 of the overlapped sheets 6 are aligned in the vicinity of the

bent parts

44, 45, and the overlapped sheets 6 are displaced in the lateral direction. Can be suppressed.

More specifically, since the annular portion 43 of the ring body 41 has two

bent portions

44 and 45, a straight portion 48 formed between the

bent portions

44 and 45, and the straight portion 48. And a curved portion 49 formed on the opposite side, and has a substantially D-shape as viewed from the bottom as a whole. Here, since the total thickness dimension of the

cover sheets

1 and 2 and the middle sheet 3 is set to be substantially the same as or slightly smaller than the length dimension of the linear portion 48, as shown in FIG. In addition, the binding holes 61 are arranged in an orderly manner in a state in which the linear portion 48 of the ring main body 41 enters the binding hole 61 of the inner paper 3. Therefore, it is possible to suppress the lateral displacement of the

cover sheets

1 and 2 and the middle sheet 3.

Further, the ring body 41 has a length in the circumferential direction of a portion other than the joining region 40 of 2π × √ {(0.5a) ² + b ² } to 2π × √ {(0.5a) ² + (b + 3). .0 mm) ² }, the ring 4 has an appropriate size corresponding to the paper 6. That is, when the ring body 41 has a length in the circumferential direction of a portion other than the joining region 40 smaller than 2π × √ {(0.5a) ² + b ² }, Since the binding side edge 63 of the binding hole 61 easily interferes, the binding holes 61 of the

overlapped cover sheets

1 and 2 and the intermediate sheet 3 are not aligned in an orderly manner, and the

cover sheets

1 and 2 and the intermediate sheet 3 are laterally moved. This will cause a shift. In other words, the end edges of the

cover sheets

1 and 2 and the inner sheet 3 opposite to the binding origin side are swelled outward. Then, the ring 4 and the edge of the binding hole 61 are easily caught when turning each page of the inner paper 3. On the other hand, when the ring body 41 has a length in the circumferential direction of a portion other than the joining region 40 larger than 2π × √ {(0.5a) ² + (b + 3.0 mm) ² }, The annular portion 43 of the ring 4 is left unreasonably, and the ring 4 is likely to collapse due to buckling. Then, the ring 4 and the edge of the binding hole 61 are easily caught when turning each page of the inner paper 3. However, since the ring main body 41 according to the present embodiment is set to a length within the above-described range, it is possible to eliminate such a problem.

Note that the present invention is not limited to the embodiment described above.

First, a note according to the second embodiment of the present invention will be described with reference to FIGS. In the following embodiments, components corresponding to the above embodiments are denoted by the same reference numerals, and detailed description thereof is omitted.

The annular portion A43 of the ring A4 has a first bent portion A44 formed at a portion corresponding to the boundary between the ring main body A41 and the connecting portion A42, and a certain distance from the first bent portion A44. A second bent portion A45 is formed in the placed portion. This fixed distance is determined according to the thickness dimension of the note N. The bent portion A44 is provided in the vicinity of the joining region A40.

Since this is the case, the binding holes 61 of the overlapped sheets 6 are arranged in an orderly manner in the vicinity of the bent portions A44 and A45, and the displacement of the overlapped sheets 6 in the lateral direction can be suppressed.

The bent portion B44 is provided in the vicinity of a joining region B40 where the distal end side of each ring body B41 and the connecting portion B42 are joined by welding. More specifically, since the ring body B41 has one bent portion B44, the bent portion B44 has an angular shape, and has a substantially tear shape as viewed from the bottom as a whole. In a state where the ring main body B41 is inserted into the binding holes 61 of the

cover sheets

1 and 2 and the inner paper 3, the binding holes 61 of the stacked sheets 6 are arranged in an orderly manner in the vicinity of the bent portion B44. Deviation in the direction can be suppressed.

Further, as shown in FIG. 8, the ring body B41 may include a plurality of fold lines B46 formed in parallel at intervals in the circumferential direction at portions other than the joining region B40. That is, as shown in FIG. 9, since the fold line B56 is provided in the horizontal band portion B51, the fold line B46 is provided in the annular portion B43 when it is closed as shown in FIG. In the present embodiment, when the annular portion B43 is made of synthetic resin, if a large force is applied in the direction in which the ring B4 is deformed by the user's hand or the like, the deformed portion is whitened, and the whitened portion is conspicuous. Problems may occur. However, if such a fold line B46 is provided, it can be made inconspicuous even if whitened. The fold line B56 provided in the horizontal band portion B51 corresponding to the fold line B46 is formed at the stage where the above-described sheet material is punched to produce the ring forming member B5.

Further, the bonding region B40 is not limited to the one formed along the belt shape, but is formed perpendicular to the belt shape as shown in FIG. 8, that is, formed along the connecting portion B42. It may be. Moreover, the joining area | region may be formed in circular shape or ellipse shape etc. which are not shown in figure.

Next, a notebook according to the fourth embodiment of the present invention is shown in FIG. In the following embodiments, components corresponding to the above embodiments are denoted by the same reference numerals, and detailed description thereof is omitted.
