Description

Technical Field

[0001] The present invention relates to a binding tool and a file folder. Background Art

[0002] There are file folders with rings for binding sheets of paper (e.g., writing paper). For example, there are ring notebooks that use a binding ring made of a spirally extending wire and insert it into a plurality of binding holes formed in a cover and writing paper. If the binding ring is made of metal or a hard resin material, it will hinder writing. In addition, there is a concern that the binding ring will press on the hand when writing. To solve this problem, for example, Patent Document 1 discloses a ring notebook with a binding ring made of a soft material that is soft enough to deform freely under a specified pressure.

[0003] Patent Document 1: Japanese Patent Application Laid-Open No. 2000-141973 Summary of the Invention Problems to be solved by the invention

[0004] For example, the binding rings of the ring notebook described in Patent Document 1 are made of a soft material. Therefore, compared to binding rings made of metal or hard resin, the binding rings are less likely to press on the hand, making writing easier. However, in the ring notebook described in Patent Document 1, for example, the cover and writing paper bound by the binding rings cannot be replaced.

[0005] In view of the above problems, the present invention aims to provide a binding tool or file folder that can replace paper and cover, is less likely to cause pressure on the hand, and is easy to write on. Means for solving problems

[0006] In order to solve the aforementioned problems, a binding tool for binding paper or the like is constructed from a deformable material, and is capable of being inserted into and removed from a binding hole of the paper or the like by deforming the material. Specifically, the binding tool of the present invention is used to bind at least one of paper and a cover, and comprises: a support portion constructed from a deformable material, which, when the bound object is bound, is inserted into the binding hole of the bound object to support the bound object; and an insertion and removal portion, which appears when the binding tool is deformed in a replacement state for replacing the bound object, and which can be freely inserted into and removed from the binding hole.

[0007] Binding tool of the present invention can replace the bound body of paper, cover by possessing the in-and-out portion that occurs that the binding tool is deformed. In addition, in binding tool of the present invention, the supporting portion of the bound body is made of deformable material, is therefore difficult to oppress the hand, and is easily written.

[0008] The bound body includes at least one of paper and a cover. Paper is, for example, writing paper. The cover includes at least one of a front cover and a back cover. The binding tool can be made of a deformable material, such as resin. The binding tool is deformable and has a binding state in which the bound body is bound and a replacement state in which the bound body is replaced. In the binding state, the region constituting the binding tool is continuous and annular. In the replacement state, a part of the region constituting the binding tool forms a discontinuous region such as a gap. In the binding state, the supporting portion includes a region constituting the binding tool that is continuous and annular, and the bound body is inserted into the binding hole to support the bound body with the continuous region. In other words, the supporting portion supports the bound body with its surface. The binding hole may be one or more. The entry and exit portion is a discontinuous region such as a gap that appears when the binding tool is deformed in the replacement state. The entry and exit portion appears in the replacement state and does not appear in the binding state. The entry and exit portion is a discontinuous area such as a gap that appears during replacement, and is freely accessible relative to the binding hole.

[0009] Here, the support portion may be cylindrical in the binding state and have a discontinuous portion which becomes a discontinuous area in the replacement state. In the replacement state, when the binding tool is deformed, an entry and exit portion which serves as a gap for free entry and exit relative to the binding hole appears in the discontinuous portion.

[0010] The opening and closing portion, which is a gap formed in the discontinuous portion, allows the binding tool to be freely inserted and removed from the binding hole. As a result, the binding tool can be freely replaced with the binding object. The discontinuous portion is a notch that is discontinuous when replaced but continuous when bound.

[0011] The discontinuous portion may also be formed in a spiral shape. The entry and exit portions may be formed at both ends of the discontinuous portion. When the binding tool is removed from the binding hole, it is disengaged from the binding hole through the gap in the entry and exit portion, and as the binding tool is rotated, the support of the support portion is gradually released. In other words, the binding tool is disengaged from the binding hole. By continuing to rotate the binding tool, the support of the support portion is completely released. In other words, the binding tool can be removed from the binding hole. When the binding tool is attached to the binding hole (when the binding tool is used to bind the object to be bound), the opposite action is performed. Specifically, when the binding tool is attached to the binding hole, the binding hole is inserted into the gap in the entry and exit portion, and as the binding tool is rotated, the binding hole is gradually supported by the support portion. In other words, the binding tool is bound to the binding hole. By continuing to rotate the binding tool, the binding hole is supported by the support portion. In other words, the binding tool can be used to bind the object to be bound. The discontinuous portion only needs to form a discontinuous region in the replacement state, and may be, for example, a linear shape.

[0012] Furthermore, the binding tool of the present invention may include a movement restricting portion that restricts movement of the binding tool relative to the binding hole in the binding state.

[0013] In the binding state, the edge of the binding hole may enter the entry and exit portion. If the edge of the binding hole enters the entry and exit portion, the bound body will move in the vertical direction, etc., and the bound body cannot be bound in the appropriate position. In addition, if the edge of the binding hole further enters the entry and exit portion, the binding state may be released. The binding tool of the present invention is capable of limiting the movement of the binding tool by having a movement limiting portion. In detail, the edge of the binding hole is prevented from entering the entry and exit portion, so that the bound body can be bound in the appropriate position. In addition, because the edge of the binding hole is difficult to enter the entry and exit portion, the binding state will not be released.

[0014] The movement restricting portion may be a thin plate-shaped flag portion provided near the entry and exit portion and projecting outward from the surface of the binding tool.

[0015] The binding tool of the present invention is provided with a flag portion, which restricts rotation. As a result, the edge of the binding hole can be prevented from entering the entry and exit portion. Furthermore, the edge of the binding hole can be prevented from entering the entry and exit portion, allowing the objects to be bound in an appropriate position. The flag portion can be provided on at least one of the ends of the discontinuous portion. By providing it at both ends, the rotation of the binding tool can be more effectively restricted. The movement restriction portion is not limited to the flag portion, as long as it can restrict the movement of the binding tool relative to the binding hole in the bound state.

[0016] Here, the present invention may also be referred to as a file folder comprising a bound object and a binding tool. Specifically, the present invention comprises: a bound object comprising at least one of paper and a cover; and a binding tool for binding the bound object, the binding tool comprising: a supporting portion formed of a deformable material, which, when the bound object is bound, is inserted into a binding hole of the bound object to support the bound object; and an entry and exit portion, which, when the bound object is replaced, appears when the binding tool is deformed and can be freely inserted into and exited from the binding hole.

[0017] File folder of the present invention can replace the bound body of paper, cover by possessing the in-and-out portion that occurs of binding tool deformation. In addition, in file folder of the present invention, the supporting portion of the bound body is made of the material that can be deformed freely, is therefore difficult to oppress the hand, and is easily written.

[0018] Furthermore, in the file of the present invention, the bound body may have a binding hole, and the binding hole may include an elongated hole having a length from one end to the other end of the binding tool.

[0019] The file folder of the present invention has a long hole as a binding hole in the bound body. Compared to a case where the binding hole at the same position is formed by arranging multiple holes that are shorter than the long hole in the longitudinal direction, the contact area between the support portion and the binding hole is increased, thereby enabling more stable binding of the bound body. In addition, compared to a case where the long hole is formed by multiple holes, the bound body can be easily replaced.

[0020] The long holes may be provided near one end and near the other end of the body to be bound.

[0021] By providing the long holes serving as binding holes near one end and the other end of the object being bound, the binding tool can also be placed near one end and the other end of the object being bound. In other words, there is no need to place the binding tool near the center of the object being bound. As a result, the binding tool is less likely to be touched by the hand, which reduces pressure on the hand and makes writing easier.

[0022] According to the present invention, a binding tool or file folder can be provided that can replace paper and cover, does not cause pressure on the hand, and allows easy writing. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Next, embodiments of the binding tool and the file folder of the present invention will be described based on the accompanying drawings. In addition, in this specification, unless otherwise specified, "upper", "lower", "left" and "right" represent the upper and lower parts of the document. Figure 1 The following description is for illustrative purposes only, and the present invention is not limited to the following contents.

[0025] <First embodiment> <Composition> like Figures 1 to 3 As shown, the first embodiment of the file folder 1 includes a bound body 2 and a binding tool 5. The bound body 2 includes writing paper 23 (an example of the paper of the present invention), a front cover 21, and a back cover 22. The writing paper 23 is a type of paper called loose-leaf paper. The writing paper 23 is a rectangular shape that is long in the vertical direction. Near one of the long sides, a plurality of binding holes 6 are linearly arranged at predetermined intervals. The binding holes 6 include regular holes 62 and elongated holes 61. The regular holes 62 are roughly square and are arranged near one of the long sides, excluding the two ends (near the center). The regular holes 62 may also have other shapes, such as a rectangle or a roughly circular shape. The elongated holes 61 are rectangular shapes that are long in the vertical direction, extending from one end to the other in the long side direction (vertical direction) of the binding tool 5. They are arranged near one end and near the other end of the bound body 2. The elongated hole 61 includes a protruding portion 61a, located on one of the long sides of the elongated hole 61 and protruding inward, and a concave portion 61b, connected to the protruding portion 61a. In this embodiment, the protruding portions 61a are located at two locations at regular intervals (the same intervals as the regular holes 62). The concave portions 61b are located at three locations at regular intervals (the same intervals as the regular holes 62). The protruding portions 61a and concave portions 61b are located on the two long sides of the elongated hole 61, the side where the binding hole 6 for the object 2 is not located. The binding hole 6 can be simplified by omitting the regular hole 62. Furthermore, by adopting a structure with the regular hole 62, it can be used in conventional file folders, improving versatility. The binding hole 6 can also have other shapes, such as a circle. The protruding portions 61a and concave portions 61b of the elongated hole 61 can be located on the other long side, or on both long sides. In addition, the long hole 61 may be configured to have a simpler structure by omitting the long hole convex portion 61 a and the long hole concave portion 61 b.

[0026] The front cover 21 and the back cover 22 cover the writing paper 23. The front cover 21 and the back cover 22 are rectangular shapes that match the shape of the writing paper 23 and are slightly larger than the writing paper 23. The front cover 21 and the back cover 22 may also be the same size as the writing paper. The front cover 21 and the back cover 22 of this embodiment are made of a transparent resin, and the grid lines of the writing paper 23 are transparent. The front cover 21 and the back cover 22 may be made of an impermeable resin, or may be made of other materials such as paper. The front cover 21 and the back cover 22 are provided with a plurality of binding holes 6 in a straight line at predetermined intervals near the long side of one side in a manner corresponding to the binding holes 6 of the writing paper 23. The binding holes 6 are the same as the writing paper 23, and have ordinary holes 62 and long holes 61. Since the ordinary holes 62 and the long holes are the same as those of the writing paper 23, their description is omitted.

[0027] Figures 4 to 12 The binding tool 5 according to the first embodiment is shown. The binding tool 5 includes a support portion 51 , a discontinuous portion 54 , an inlet and outlet portion 52 , and flags 53 a and 53 b as a movement restriction portion 53 .

[0028] The binding tool 5 is made of a deformable resin and has Figures 1 to 4 、 Figure 12 The binding state of the binding body 2 shown and Figures 5 to 11 The figure shows a replacement state of the body 2 to be bound. In the binding state, the region constituting the binding tool 5 is continuous and annular, more specifically, cylindrical. In the replacement state, a gap is formed in a portion of the region constituting the binding tool 5, forming a discontinuous region, more specifically, a discontinuous portion 54.

[0029] In the binding state, the support portion 51 forms a continuous cylindrical region of the binding tool 5, contacts the binding holes 6 of the objects 2, and supports the objects 2 with the continuous region. In other words, the support portion 51 supports the objects 2 with its surface.

[0030] The discontinuous portion 54 is formed by a spiral cut. In the binding state, the adjacent edges of the cut are substantially continuous and abut each other. In the replacement state, the binding tool 5 is deformed, for example, by applying a force in the vertical direction, to form a discontinuous area.

[0031] The entry and exit portion 52 is formed by gaps formed at both ends of the discontinuous portion 54. By deforming the binding tool, for example, by applying a force in the up-down direction, or by applying a force in a manner that pulls apart the ends of the discontinuous portion 54, the entry and exit portion 52 appears as a gap that allows for free entry and exit from the long hole 61 serving as the binding hole 6. The entry and exit portion 52a located at the center side of the body 2 to be bound (at Figure 6The entry and exit portion 52a is the end portion of the linear cutout and has a triangular cutout portion 52a1 at the end portion on the central side of the bound body 2. The triangular cutout portion 52a1 functions as a relief portion for suppressing interference between the binding tool 5 and the end portion of the bound body 2 when the file folder 1 is used (when the bound body 2 is turned over). In addition, the triangular cutout portion 52a1 enables easy entry and exit of the binding hole 6. The entry and exit portion 52b located on the end side of the bound body 2 (at Figure 6 The upper side is formed by a straight cutout parallel to the central axis of the binding tool 5 and is arranged at a position eccentric to the central axis of the binding tool 5 when viewed from the side. Flags 53a and 53b serving as the movement limiting portion 53 are provided on both sides of the straight cutout serving as the entry and exit portion 52b. Alternatively, the entry and exit portion 52a may be arranged at a position eccentric to the central axis of the binding tool 5 when viewed from the side, and the entry and exit portion 52b (at the Figure 6 The upper side is in the middle) and is set at a position overlapping with the central axis of the binding tool 5 when viewed from the side.

[0032] The flags 53a and 53b as the movement restriction parts 53 restrict the movement of the binding tool 5 relative to the binding hole 6 in the binding state. The flags 53a and 53b are provided near the inlet and outlet part 52b and are formed of plate-like parts protruding outward from the surface of the binding tool 5. The flags 53a and 53b have the following features: Figure 6 The right side) and the flag portion 53b (in Figure 6 The flag portion 53b is formed to be slightly larger than the flag portion 53a, but the flag portion 53a may also be formed to be slightly larger than the flag portion 53b.

[0033] <How to use> Next, the method of using the binding tool 5 and the file folder 1 will be described. The following method of use is an example, and the order can be changed as appropriate. In the following description, the case of binding the binding tool 5 in the long hole 61 on the upper side of the file folder 1 is used as an example.

[0034] First, a case where the binding tool 5 is attached to the file folder 1 will be described. Figure 8 The document file 1 having the binding tool 5 of the first embodiment is shown in use, with the binding tool 5 separated from the bound body 2. The bound body 2 is arranged with the front cover 21, writing paper 23, and back cover 22 arranged in this order from the top, with the inner side of the front cover 21 being at the top.

[0035] Figure 9The document 1 is shown in the state where the file folder 1 equipped with the binding tool 5 of the first embodiment is in use, and the entry and exit portion 52 of the binding tool 5 begins to enter the long hole 61 of the binding body 2. The binding tool 5 is deformed, and the entry and exit portion 52a of the binding tool 5 appears (forming a gap), and the entry and exit portion 52a is inserted into the lower side of the long hole 61. That is, in this inserted state, the entry and exit portion 52a is located at the same position as the entry and exit portion 52a in the long hole 61. Figure 9 The binding tool 5 is on the opposite side of the side of the body 2 to be bound that is visually recognized, so it is not shown here. More specifically, the edge portion 61c of the long hole formed between the long side of the body 2 to be bound and the long hole 61 is inserted into the inlet and outlet portion 52a. Then, the binding tool 5 is rotated clockwise ( ) with the axis as the center when the binding tool 5 is viewed from above (hereinafter the same in this specification). Figure 9 、 Figure 10 The arrow indicates the direction of rotation. As the binding tool 5 rotates, the edge portion 61 c of the long hole gradually moves toward the upper side of the binding tool 5 along the spiral discontinuous portion 54.

[0036] Figure 10 、 Figure 11 The figure shows a state in which a file folder equipped with the binding tool of the first embodiment is used and the binding tool 5 is rotated. As the binding tool 5 rotates, the edge portion 61c of the long hole gradually moves toward the upper side of the binding tool 5 along the spiral discontinuous portion 54. When the binding tool 5 continues to rotate, the flag portions 53a and 53b contact the upper side of the long hole 61 of the binding body 2 and are restricted from rotating. The binding tool 5 is deformed so that the flag portion 53a (at the top of the long hole 61) of the flag portions 53a and 53b is Figure 11 Then, the flag portion 53a passes through the long hole 61 from the back side of the binding tool, and the flag portion 53a and the flag portion 53b are located at the top of the binding tool 2, and the edge portion 61c of the long hole is stored in the interior of the cylindrical binding tool 5 (refer to Figure 12 As a result, the support portion 51 comes into contact with the long hole 61 of the binding body 2 and supports the binding body 2 .

[0037] Next, the binding tool 5 is removed from the file folder 1. First, the binding tool 5 is deformed, and the flag portion 53a passes through the long hole 61, so that the flag portion 53a (at the top of the binding body 2) and the flag portion 53b are separated. Figure 11The back side in the middle is located on the inner side of the body 2 to be bound. Then, the binding tool 5 rotates counterclockwise when the binding tool 5 is viewed from above. As the binding tool 5 rotates, the binding tool 5 gradually disengages from the long hole 61. As the binding tool 5 continues to rotate, the binding tool 5 is eventually completely disengaged from the long hole 61. In addition, it is also possible to form a relationship opposite to the clockwise and counterclockwise relationship in the assembly and disassembly action of the binding tool 5 described so far, that is, when the binding tool 5 is viewed from above, it rotates counterclockwise so that the inlet and outlet portion 52 enters the long hole 61 of the body 2 to be bound, and when it rotates clockwise, the binding tool 5 disengages from the long hole 61.

[0038] <Effect> In the file folder 1 having the binding tool 5 of the first embodiment, the binding tool 5 is made of a deformable resin and includes a discontinuous portion 54 and an inlet and outlet portion 52, thereby enabling the bound body 2 to be freely replaced. More specifically, the edge portion 61c of the long hole can be freely inserted and removed from the inlet and outlet portion 52, which is a gap formed at the end of the discontinuous portion 54 formed by the slit. By inserting the edge portion 61c of the long hole into the inlet and outlet portion 52 and rotating the binding tool 5 so that the edge portion 61c of the long hole advances along the spiral discontinuous portion 54, the binding tool 5 can be attached to or removed from the long hole 61. In other words, the binding tool 5 can freely replace the bound body 2. In addition, the binding tool 5 of the first embodiment is made of a deformable resin, so it is less likely to put pressure on the hand and is easy to write with.

[0039] In addition, the binding tool 5 of the first embodiment is provided with a movement limiting portion 53, which can limit the movement of the binding tool 5. Specifically, in the binding state, the binding tool 5 is prevented from rotating in such a way that the edge portion 61c of the binding hole enters the entry and exit portion 52, so that the bound body 2 can be bound in an appropriate position. In addition, since the edge portion 61c of the long hole is difficult to enter the entry and exit portion 52, the binding state will not be released. The movement limiting portion 53 of the binding tool 5 of the first embodiment is composed of flag portions 53a and 53b. When the folder 1 is closed, the flag portions 53a and 53b are sandwiched between the back cover 22 and the writing paper 23, and their rotation is restricted. In addition, when the folder 1 is opened, except when the flag portions 53a and 53b are exposed to the top, the flag portions 53a and 53b are sandwiched between the front cover 21 and the writing paper 23, and their rotation is restricted. Furthermore, the positions of the entry / exit portion 52a and the entry / exit portion 52b are offset. When the flags 53a and 53b are sandwiched between the cover 21 and the writing paper 23, the entry / exit portion 52a is located in a position where it is difficult to reach the edge 61c of the elongated hole. Because the entry / exit portion 52b has the flags 53a and 53b, the edge 61c of the elongated hole cannot enter. In other words, in the first embodiment, the entry / exit portion 52 is prevented from causing the edge 61c of the elongated hole to enter. If the edge 61c of the elongated hole enters the entry / exit portion 52, there is a risk of vertical movement of the object 2 being bound. However, in the present embodiment, the vertical movement of the object 2 is restricted, allowing the object 2 to be bound in an appropriate position. Furthermore, because the movement restriction portion 53 is positioned off-center from the central axis of the binding tool 5, a larger amount of writing paper 23 can be bound compared to a case where the movement restriction portion 53 is positioned on the central axis of the binding tool 5.

[0040] Furthermore, the file folder 1 of the first embodiment includes a convex portion 61a and a concave portion 61b in the elongated hole 61. The convex portion 61a restricts the left-right movement of the bound body 2. Furthermore, the concave portion 61b facilitates the passage of the flags 53a and 53b through the elongated hole 61. In other words, replacement of the bound body 2 is facilitated.

[0041] <Second embodiment> <Composition> Next, a document file 1 including a binding tool 5 according to a second embodiment will be described. Components identical to those of the first embodiment are denoted by the same reference numerals, and their description will be omitted. The description will focus on differences from the first embodiment. Figure 13 This figure shows a front view of a file folder equipped with the binding tool according to the second embodiment. Figure 14 A side view showing the binding tool according to the second embodiment (binding state). Figure 15 A side view showing the binding tool according to the second embodiment (replacement state).

[0042] The file folder 1 equipped with the binding tool 5 of the second embodiment has a simpler structure than the file folder 1 equipped with the binding tool 5 of the first embodiment. Specifically, regarding the bound body 2, the long hole 61 is a rectangular shape that is long in the vertical direction and has a simple structure without the long hole protrusion 61a and the long hole concave portion 61b.

[0043] In addition, the binding tool 5 is a simple structure without the flag portions 53a and 53b. The binding tool 5 includes a supporting portion 51, a discontinuous portion 54, and an inlet and outlet portion 52. In the binding state, the supporting portion 51 is a region that constitutes the binding tool 5 and is continuous and cylindrical, and is inserted into the binding hole 6 of the bound body 2 to support the bound body 2 with a continuous region, in other words, with a surface. The discontinuous portion 54 is composed of a cut formed in a spiral shape. The inlet and outlet portion 52 is composed of gaps formed at both ends of the discontinuous portion 54. The inlet and outlet portion 52 appears as a gap that can freely enter and exit from the long hole 61 when the binding tool 5 is deformed, for example, by applying a force in the up and down directions, or by applying a force in a manner that pulls apart the ends of the discontinuous portion 54. In the binding tool 5 of the second embodiment, the inlet and outlet portion 52 is formed along the cut of the spiral discontinuous portion 54. In other words, the inlet and outlet portion 52 of the second embodiment is composed of an inclined cut. The inlet and outlet portion 52a (at Figure 14 、 Figure 15 The lower side) and the inlet and outlet 52b (in Figure 14 、 Figure 15 The positions of the binding tool 5 and the binding tool 5 are staggered in the peripheral direction so that when viewed from the side, one side is visually identified as being located at a position overlapping with the central axis of the binding tool 5, and the other side is visually identified as being located at a position eccentric from the central axis of the binding tool 5.

[0044] <How to use> First, the situation of installing the binding tool 5 on the file folder 1 is described. The binding tool 5 is deformed, and the entry and exit portion 52a of the binding tool 5 appears (forming a gap), and the edge portion 61c of the long hole of the bound body 2 is inserted into the entry and exit portion 52a. Then, the binding tool 5 rotates clockwise around the central axis. As the binding tool 5 rotates, the edge portion 61c of the long hole gradually moves upward along the spiral discontinuous portion 54. If the binding tool 5 rotates further, the edge portion 61c of the long hole is accommodated inside the cylindrical binding tool 5. As a result, the support portion 51 contacts the long hole 61 of the bound body 2 and supports the bound body 2.

[0045] Next, the process of removing the binding tool 5 from the file folder 1 will be described. First, the binding tool 5 is deformed, and the edge portion 61c of the long hole is inserted into the entry and exit portion 52b. Then, the binding tool 5 is rotated counterclockwise. As the binding tool 5 rotates, the binding tool 5 gradually disengages from the long hole 61. If the binding tool 5 continues to rotate, the binding tool 5 will eventually be completely disengaged from the long hole 61. In addition, since the binding tool 5 of the second embodiment does not have the flag portions 53a and 53b, the edge portion 61c of the long hole can also be inserted from the entry and exit portion 52b to perform the above steps.

[0046] <Effect> The file folder 1 having the binding tool 5 of the second embodiment has a simpler structure than the first embodiment. Furthermore, the binding tool 5 of the file folder 1 having the binding tool 5 of the second embodiment is made of a deformable resin and includes a discontinuous portion 54 and an inlet and outlet portion 52, thereby enabling free replacement of the bound object 2. The binding tool 5 of the second embodiment can be easily removed from either the inlet and outlet portion 52a or the inlet and outlet portion 52b. Furthermore, since the binding tool 5 of the second embodiment is made of a deformable resin, it is less likely to cause pressure on the hand, making writing easier.

[0047] Furthermore, if the positions of the inlet / outlet portions 52a and 52b are aligned, the object 2 may alternately enter the inlet / outlet portions 52a and 52b, thereby increasing the distance traveled when the object 2 moves up and down. In the file folder 1 equipped with the binding tool 5 of the second embodiment, the positions of the inlet / outlet portions 52a and 52b in the outer circumferential direction are offset, making it difficult to alternately enter the inlet / outlet portions 52a and 52b. As a result, the movement of the binding tool 5 can be suppressed.

[0048] <Third embodiment> <Composition> Next, a document file 1 including a binding tool 5 according to a third embodiment will be described. The same components as those in the previously described embodiment are denoted by the same reference numerals, and their description will be omitted. The description will focus on the differences from the previously described embodiment. Figure 16 A side view showing the binding tool according to the third embodiment (binding state). Figure 17 A side view showing the binding tool according to the third embodiment (replacement state).

[0049] Although not shown in the figure, the file folder 1 equipped with the binding tool 5 of the third embodiment is the bound body 2 of the second embodiment, and the long hole 61 is a rectangular shape long in the vertical direction, and has a simple structure without the long hole protrusion 61a and the long hole concave portion 61b.

[0050] The flags 53a, 53b, 53c, and 53d of the binding tool 5 are different from those of the first embodiment. The binding tool 5 includes a support portion 51, a discontinuous portion 54, an entry / exit portion 52, and the flags 53a, 53b, 53c, and 53d serving as a movement restriction portion 53. In the binding state, the support portion 51 forms a continuous ring (cylindrical) region that constitutes the binding tool 5. The support portion 51 is inserted into the binding hole 6 of the object 2 to support the object 2 with a continuous region (surface). The discontinuous portion 54 is formed by a spiral cutout. The entry / exit portion 52 is formed by cutouts formed at both ends of the discontinuous portion 54. The entry / exit portion 52 is formed as a gap that allows free access to the binding hole by deforming the binding tool, for example, by applying a force in the vertical direction or by applying a force to the ends of the discontinuous portion 54. In the binding tool 5 of the third embodiment, the inlet and outlet portion 52 is formed by linear cutouts parallel to the central axis of the binding tool 5 at both ends of the cutout of the spiral discontinuous portion 54. Figure 16 、 Figure 17 The lower side) and the inlet and outlet 52b (in Figure 16 、 Figure 17 The upper side is in the middle) and is formed in such a way that the positions in the peripheral direction are the same.

[0051] The flags 53a, 53b, 53c, and 53d serving as the movement restricting portions 53 are provided near the inlet and outlet portions 52a and 52b, and are formed of protrusions that protrude axially from the ends of the binding tool 5. The flags 53a, 53b, 53c, and 53d provided near the inlet and outlet portions 52a and 52b include flags 53c and 53d provided near the inlet and outlet portions 52a and flags 53a and 53b provided near the inlet and outlet portions 52b.

[0052] <How to use> First, the situation of attaching the binding tool 5 to the file folder 1 will be described. The binding tool 5 deforms, and the entry and exit portion 52a of the binding tool 5 appears (forming a gap), and the edge portion 61c of the long hole of the binding body 2 is inserted into the entry and exit portion 52a. Next, the binding tool 5 rotates clockwise around the central axis. As the binding tool 5 rotates, the edge portion 61c of the long hole gradually advances upward along the spiral discontinuous portion 54. As the binding tool 5 rotates, the flag portions 53c and 53d repeatedly pass through the long hole 61. If the binding tool 5 rotates further, the edge portion 61c of the long hole is stored inside the cylindrical binding tool 5. At this time, the flag portions 53a, 53b, 53c, and 53d are located between the back cover 22 and the writing paper 23. The support portion 51 is in contact with the long hole 61 of the binding body 2 to support the binding body 2.

[0053] Next, the situation of removing the binding tool 5 from the folder 1 is described. First, the binding tool 5 is deformed, and the edge portion 61c of the long hole is inserted into the entry and exit portion 52b. Then, the binding tool 5 is rotated counterclockwise. If the binding tool 5 is rotated, the binding tool 5 gradually detaches from the long hole 61. As the binding tool 5 rotates, the flag portions 53c and 53d repeatedly pass through the long hole 61. If the binding tool 5 continues to rotate, the binding tool 5 will eventually completely detach from the long hole 61. In addition, the binding tool 5 of the third embodiment can make the edge portion 61c of the long hole enter from the entry and exit portion 52b and perform the above steps.

[0054] <Effect> The binding tool 5 of the file folder 1 equipped with the binding tool 5 of the third embodiment is made of a deformable resin and includes a discontinuous portion 54 and an inlet and outlet portion 52, thereby enabling free replacement of the bound object 2. The binding tool 5 of the third embodiment can be easily removed from either the inlet and outlet portion 52a or the inlet and outlet portion 52b. In addition, the binding tool 5 of the third embodiment is made of a deformable resin, so it is less likely to cause pressure on the hand and is easy to write with.

[0055] Furthermore, the binding tool 5 of the third embodiment includes a movement restriction portion 53, which can restrict the movement of the binding tool 5. Specifically, in the binding state, the edge portion 61c of the binding hole is prevented from entering the entry / exit portion 52, allowing the object 2 to be bound in the proper position. Furthermore, since the edge portion 61c of the elongated hole is difficult to enter the entry / exit portion 52, the binding state is not released. Furthermore, when the file folder 1 is closed, the movement restriction portion 53 of the binding tool 5 of the third embodiment is sandwiched between the back cover 22 and the writing paper 23, restricting rotation. Furthermore, when the file folder 1 is open, except when the movement restriction portion 53 is exposed at the top, the movement restriction portion 53 is sandwiched between the back cover 22 and the writing paper 23, restricting rotation. In other words, in the binding tool 5 of the third embodiment, the edge portion 61c of the elongated hole is prevented from entering the entry / exit portion 52. In this embodiment, the binding tool 5 can restrict the vertical movement of the object 2 to be bound, allowing the object 2 to be bound in the proper position. Alternatively, the movement restriction portion 53 may be sandwiched between the cover 21 and the writing paper 23 so as to restrict rotation.

[0056] <Fourth embodiment> <Composition> Next, a document file 1 including a binding tool 5 according to a fourth embodiment will be described. The same components as those in the previously described embodiment are denoted by the same reference numerals, and their description will be omitted. The description will focus on the differences from the previously described embodiment. Figure 18 A side view showing the binding tool according to the fourth embodiment (binding state). Figure 19A side view showing the binding tool according to the fourth embodiment (replacement state). Figure 20 A development view of a binding tool according to a fourth embodiment is shown. Figure 21 This is a side view showing the binding tool according to the fourth embodiment when opened.

[0057] Although not shown in the figure, the file folder 1 equipped with the binding tool 5 of the fourth embodiment is the bound body 2 of the second embodiment, and the long hole 61 is a rectangular shape long in the vertical direction, and has a simple structure without the long hole protrusion 61a and the long hole concave portion 61b.

[0058] The binding tool 5 of the fourth embodiment has a double-tube structure consisting of an outer portion 56a and an inner portion 56b, and does not have the flag portions 53a and 53b. The binding tool 5 includes an outer portion 56a and an inner portion 56b. Each of the outer portion 56a and the inner portion 56b has a supporting portion 51 (51a, 51b), a discontinuous portion 54 (54a, 54b), and an entry / exit portion 52 (52a, 52b, 52c). The upper ends of the outer portion 56a and the inner portion 56b are connected. In the binding state, the supporting portion 51 (51a, 51b) forms a continuous region that forms the binding tool 5, forming a double-tube structure. The inner portion 56b is in contact with the binding hole 6 of the object 2 to support the object 2 with a continuous region (surface). The discontinuous portion 54 (54a, 54b) is formed by a spiral cutout. The discontinuous portion 54a of the outer portion 56a and the discontinuous portion 54b of the inner portion 56b are formed by spiral cuts in opposite directions. The entry and exit portions 52 (52a, 52b, 52c) include the entry and exit portion 52a of the outer portion 56a, the entry and exit portion 52c formed at the connection between the outer portion 56a and the inner portion 56b, and the entry and exit portion 52b of the inner portion 56b. The entry and exit portion 52a of the outer portion 56a and the entry and exit portion 52b of the inner portion 56b are located opposite each other. In other words, the entry and exit portion 52 is located on the opposite side of the entry and exit portion 52. The entry and exit portion 52 is formed as a gap for freely entering the binding hole by deforming the binding tool, for example, by applying a force in the vertical direction or by applying a force to pull apart the ends of the discontinuous portion 54.

[0059] <How to use> First, a case where the binding tool 5 is attached to the file folder 1 will be described. Figure 21 The arrows indicate the direction of the edge portion 61c of the long hole. The outer portion 56a and the inner portion 56b overlap, but for ease of understanding, the outer portion 56a and the inner portion 56b are overlapped. Figure 21In the figure, the outer portion 56a and the inner portion 56b are expanded to show the outer portion 56a and the inner portion 56b. The binding tool 5 deforms, and the entry and exit portion 52a of the binding tool 5 (the entry and exit portion 52a of the outer portion 56a) appears (forming a gap), and the edge portion 61c of the elongated hole is inserted into the entry and exit portion 52a. Next, the binding tool 5 rotates counterclockwise about the central axis. As the binding tool 5 rotates, the edge portion 61c of the elongated hole gradually advances upward along the spiral discontinuous portion 54a formed on the outer portion 56a. As the binding tool 5 rotates, the binding tool 5 rotates so that the edge portion 61c of the elongated hole is always inserted into the entry and exit portion 52a of the outer portion 56a. If the binding tool 5 rotates further, the edge portion 61c of the elongated hole reaches the entry and exit portion 52c formed at the connection between the outer portion 56a and the inner portion 56b, and then gradually advances downward along the spiral discontinuous portion 54b formed on the inner portion 56b. When the edge portion 61c of the long hole reaches the inlet and outlet portion 52b of the inner portion 56b, the edge portion 61c of the long hole is accommodated in the interior of the double-tube binding tool 5. As a result, the support portion 51 of the inner portion 56b is inserted into the long hole 61 of the binding body 2 and faces or contacts the end thereof, thereby supporting the binding body 2.

[0060] Next, the process of removing the binding tool 5 from the folder 1 will be described. First, the binding tool 5 is deformed, and the edge portion 61c of the long hole is inserted into the inlet and outlet portion 52b of the inner portion 56b. Then, the binding tool 5 is rotated clockwise. If the binding tool 5 rotates, it gradually moves upward along the spiral discontinuous portion 54b formed on the inner portion 56b. If the binding tool 5 rotates further, the edge portion 61c of the long hole reaches the inlet and outlet portion 52c formed at the connection between the outer portion 56a and the inner portion 56b, and then gradually moves downward along the spiral discontinuous portion 54a formed on the outer portion 56a. When the edge portion 61c of the long hole reaches the inlet and outlet portion 52a of the outer portion 56a, the binding tool 5 is removed from the long hole 61.

[0061] <Effect> The binding tool 5 of the file folder 1 equipped with the binding tool 5 of the fourth embodiment is made of a freely deformable resin and includes discontinuous portions 54 ( 54a , 54b ) and insertion and removal portions 52 ( 52a , 52b , 52c ), thereby enabling free replacement of the bound object 2 . Furthermore, the binding tool 5 of the file folder 1 equipped with the binding tool 5 of the fourth embodiment has a double-tube structure, thereby enabling more stable binding of the bound object 2 . Furthermore, the binding tool 5 of the fourth embodiment, being made of a freely deformable resin, does not cause any pressure on the hand, making writing easier.

[0062] Furthermore, in the file folder 1 equipped with the binding tool 5 of the fourth embodiment, the positions of the inlet and outlet parts 52a and 52b in the outer circumferential direction are offset, making it difficult to enter the inlet and outlet parts 52a and 52b at the same time.

[0063] <Fifth embodiment> Next, a file folder 1 including a binding tool 5 according to a fifth embodiment will be described. The same components as those in the previously described embodiment are denoted by the same reference numerals, and their description will be omitted. The description will focus on the differences from the previously described embodiment. Figure 22 A perspective view showing a binding tool according to a fifth embodiment (binding state). Figure 23 A perspective view showing a binding tool according to a fifth embodiment (replacement state).

[0064] Although not shown in the figure, the file folder 1 equipped with the binding tool 5 of the fifth embodiment is the bound body 2 of the second embodiment, and the long hole 61 is a rectangular shape that is long in the vertical direction and has a simple structure without the long hole protrusion 61a and the long hole concave portion 61b.

[0065] The binding tool 5 includes a support portion 51, a discontinuous portion 54, an entry / exit portion 52, and a movement restriction portion 53. In the binding state, the support portion 51 forms a continuous cylindrical region that connects to the long hole 61 of the object 2 to be bound, supporting the object 2 with a continuous region (surface). The discontinuous portion 54 is formed by a linear cutout parallel to the central axis of the binding tool 5. In this embodiment, the discontinuous portion 54 serves as the entry / exit portion 52. Specifically, the entry / exit portion 52 is deformed by the binding tool, exerting a force that expands the discontinuous portion 54, thereby appearing as a linear gap that can be freely entered from the long hole 61.

[0066] The movement restricting portion 53 is provided along the entry and exit portion 52 , in other words, along the discontinuous portion 54 , and is composed of two opposing rectangular pieces 53 e and 53 f that protrude outward from the surface of the binding tool 5 .

[0067] <How to use> First, the binding tool 5 is attached to the file folder 1. The binding tool 5 deforms. Specifically, the discontinuous portion 54 expands, creating an entry / exit section 52 for the binding tool 5 (forming a gap). The edge 61c of the elongated hole in the object 2 is inserted into the entry / exit section 52. As a result, the edge 61c of the elongated hole is retracted into the interior of the cylindrical binding tool 5. At this point, the movement restriction section 53 is positioned between the cover 21 and the writing paper 23. The support section 51 is inserted into the elongated hole 61 in the object 2, facing or contacting its end, thereby supporting the object 2.

[0068] Next, the process of removing the binding tool 5 from the file folder 1 will be described. The binding tool 5 deforms, specifically, the discontinuous portion 54 expands, and the entry and exit portion 52 of the binding tool 5 appears (forming a gap), and the edge portion 61c of the long hole of the bound object 2 is removed from the entry and exit portion 52.

[0069] <Effect> The binding tool 5 of the folder 1 having the binding tool 5 of the fifth embodiment is made of a deformable resin and has a discontinuous portion 54 and an inlet and outlet portion 52, thereby enabling the free replacement of the bound body 2. The binding tool 5 of the fifth embodiment can replace the bound body 2 simply by expanding the discontinuous portion 54. In addition, the supporting portion 51 of the binding tool 5 of the fifth embodiment, which supports the bound body 2, is made of a deformable resin, so that it is difficult to press the hand and is easy to write. In addition, the binding tool 5 of the fifth embodiment can limit the movement of the binding tool 5 by having the sheet portions 53e and 53f as the movement limiting portion 53.

[0070] <Sixth embodiment> Next, a document file 1 including a binding tool 5 according to a sixth embodiment will be described. The same components as those in the previously described embodiment are denoted by the same reference numerals, and their description will be omitted. The description will focus on the differences from the previously described embodiment. Figure 24 A perspective view showing a binding tool according to a sixth embodiment (binding state). Figure 25 A perspective view showing a binding tool according to a sixth embodiment (replacement state).

[0071] Although not shown in the figure, the file folder 1 equipped with the binding tool 5 of the sixth embodiment is the bound body 2 of the second embodiment, and the long hole 61 is a rectangular shape that is long in the vertical direction and has a simple structure without the long hole protrusion 61a and the long hole concave portion 61b.

[0072] The binding tool 5 includes a support portion 51, a discontinuous portion 54, an entry / exit portion 52, and a movement restriction portion 53. In the binding state, the support portion 51 is a continuous cylindrical region that forms the binding tool 5. It is in contact with the long hole 61 of the object 2 to be bound, supporting the object 2 with a continuous region (surface). The discontinuous portion 54 is formed by a straight cutout parallel to the central axis of the binding tool 5. In this embodiment, the discontinuous portion 54 serves as the entry / exit portion 52. Specifically, the entry / exit portion 52 is deformed by the binding tool, specifically, by applying a force that expands the discontinuous portion 54, and appears as a straight gap that can be freely entered from the long hole 61.

[0073] The movement restricting portion 53 is provided along the entry and exit portion 52, in other words, along the discontinuous portion 54, and is composed of two rectangular pieces 53g and 53h that protrude outward from the surface of the binding tool 5. In the sixth embodiment, unlike the fifth embodiment, the two pieces 53g and 53h are not opposed to each other (do not overlap) but are alternately provided.

[0074] <How to use> First, the binding tool 5 is attached to the file folder 1. The binding tool 5 deforms. Specifically, the discontinuous portion 54 expands, creating an entry / exit section 52 for the binding tool 5 (forming a gap). The edge 61c of the elongated hole in the object 2 is inserted into the entry / exit section 52. As a result, the edge 61c of the elongated hole is retracted into the interior of the cylindrical binding tool 5. At this point, the movement restriction section 53 is positioned between the cover 21 and the writing paper 23. The support section 51 is inserted into the elongated hole 61 in the object 2, facing or contacting its end, thereby supporting the object 2.

[0075] Next, the process of removing the binding tool 5 from the file folder 1 will be described. The binding tool 5 deforms, specifically, the discontinuous portion 54 expands, and the entry and exit portion 52 of the binding tool 5 appears (forming a gap), and the edge portion 61c of the long hole of the bound object 2 is removed from the entry and exit portion 52.

[0076] <Effect> The binding tool 5 of the file folder 1 having the binding tool 5 of the sixth embodiment is made of a deformable resin and has a discontinuous portion 54 and an inlet and outlet portion 52, so that the bound body 2 can be freely replaced. The binding tool 5 of the sixth embodiment can replace the bound body 2 simply by expanding the discontinuous portion 54. In addition, the binding tool 5 of the sixth embodiment is made of a deformable resin, so it is difficult to press the hand and it is easy to write. In addition, the binding tool 5 of the sixth embodiment can limit the movement of the binding tool 5 by having two pieces 53g and 53h as the movement limiting portion 53. In addition, the two pieces 53g and 53h as the movement limiting portion 53 of the sixth embodiment are alternately arranged in a non-overlapping manner, so that the discontinuous portion 54 can be easily expanded by pinching the two pieces 53g and 53h.

[0077] <Seventh embodiment> <Composition> Next, a document file 1 including a binding tool 5 according to a seventh embodiment will be described. The same components as those in the previously described embodiment are denoted by the same reference numerals, and their description will be omitted. The description will focus on the differences from the previously described embodiment. Figure 26 A side view showing the binding tool according to the seventh embodiment (binding state). Figure 27 A side view showing the binding tool according to the seventh embodiment (replacement state).

[0078] Although not shown in the figure, the file folder 1 having the binding tool 5 of the seventh embodiment is the bound body 2 of the second embodiment, and the long hole 61 is a rectangular shape that is long in the vertical direction and has a simple structure without the long hole convex portion 61a and the long hole concave portion 61b.

[0079] The binding tool 5 includes a support portion 51, a discontinuous portion 54, an entry / exit portion 52, and engaging portions 55 (55a, 55b). In the binding state, the support portion 51 is a continuous cylindrical region that forms the binding tool 5. It contacts the binding hole 6 of the object 2 to support the object 2 with a continuous region (surface). The discontinuous portion 54 is formed by a linear cutout parallel to the central axis of the binding tool 5. In this embodiment, the discontinuous portion 54 serves as the entry / exit portion 52. Specifically, the entry / exit portion 52 is deformed by the binding tool 5, specifically, by the application of a force that expands the discontinuous portion 54, creating a linear gap that allows for easy entry from the elongated hole 61. The discontinuous portion 54 of the binding tool 5 is formed thicker than the other regions, and engaging portions 55 (55a, 55b) are provided in the discontinuous portion 54. The engaging portion 55 ( 55 a , 55 b ) includes a protruding engaging convex portion 55 a and an engaging concave portion 55 b that is recessed for engagement with the engaging convex portion 55 a .

[0080] <How to use> First, the binding tool 5 is attached to the file folder 1. The binding tool 5 deforms. Specifically, the discontinuous portion 54 expands, creating an entry / exit portion 52 for the binding tool 5 (a gap). The edge 61c of the elongated hole in the binding body 2 is inserted into the entry / exit portion 52. The engaging portions 55 (55a, 55b) engage, and the edge 61c of the elongated hole is accommodated within the cylindrical binding tool 5.

[0081] Next, the process of removing the binding tool 5 from the file folder 1 will be described. The binding tool 5 deforms. Specifically, the discontinuous portion 54 expands, the engagement of the engaging portions 55 (55a, 55b) is disengaged, and the entry and exit portion 52 of the binding tool 5 is opened (a gap is formed). The edge portion 61c of the elongated hole of the bound object 2 is removed from the entry and exit portion 52.

[0082] <Effect> The binding tool 5 of the seventh embodiment of the file folder 1 is made of a freely deformable resin and includes a discontinuous portion 54 and an insertion / extraction portion 52, thereby enabling the free replacement of the bound object 2. The binding tool 5 of the seventh embodiment allows the replacement of the bound object 2 simply by expanding the discontinuous portion 54. Furthermore, the inclusion of the engaging portions 55 (55a, 55b) ensures a stable binding state. Furthermore, the support portion 51 of the seventh embodiment of the binding tool 5, which supports the bound object 2, is made of a freely deformable resin, thus minimizing pressure on the hand and facilitating writing.

[0083] <Eighth embodiment> <Composition> Next, a document file 1 including a binding tool 5 according to an eighth embodiment will be described. The same components as those in the previously described embodiment are denoted by the same reference numerals, and their description will be omitted. The description will focus on the differences from the previously described embodiment. Figure 28 A perspective view showing a binding tool according to an eighth embodiment (binding state). Figure 29 A perspective view showing a binding tool according to an eighth embodiment (replacement state).

[0084] Although not shown in the figure, the file folder 1 having the binding tool 5 of the eighth embodiment is the bound body 2 of the second embodiment, and the long hole 61 is a rectangle that is long in the vertical direction and has a simple structure without the long hole convex portion 61a and the long hole concave portion 61b.

[0085] The binding tool 5 of the eighth embodiment has a double-tube structure consisting of an outer portion 56a and an inner portion 56b. The binding tool 5 includes an outer portion 56a and an inner portion 56b, each of which includes a support portion 51 (51a, 51b), a discontinuous portion 54 (54a, 54b), and an entry / exit portion 52 (52a, 52b). Unlike the fourth embodiment, in the eighth embodiment, the outer portion 56a and the inner portion 56b are formed from different components. In the binding state, the support portion 51 (51a, 51b) has a continuous area forming the double-tube structure, while the inner portion 56b is in contact with the elongated hole 61 of the object 2 to support the object 2 with a continuous area (surface). The discontinuous portions 54 (54a, 54b) are provided on each of the outer portion 56a and the inner portion 56b and are formed as linear cutouts parallel to the central axis of the binding tool 5. In this embodiment, the discontinuous portions 54 (54a, 54b) serve as the entry and exit portions 52 (52a, 52b). Specifically, the entry and exit portions 52 (52a, 52b) are deformed by the binding tool 5, specifically, by the force exerted on the discontinuous portions 54 (54a, 54b) to expand, creating a linear gap that allows for easy access through the elongated hole 61. The discontinuous portions 54a of the outer portion 56a and the discontinuous portions 54b of the inner portion 56b are arranged so as not to overlap. In this embodiment, the discontinuous portions 54a of the outer portion 56a are located on the opposite side of the discontinuous portions 54b of the inner portion 56b.

[0086] <How to use> First, let's describe how the binding tool 5 is attached to the file folder 1. The binding tool 5 deforms. Specifically, the discontinuous portion 54b of the inner portion 56b expands, creating the entry / exit section 52b of the binding tool 5 (forming a gap). The edge 61c of the elongated hole in the bound object 2 is inserted into the entry / exit section 52b of the inner portion 56b. Subsequently, the discontinuous portion 54a of the outer portion 56a expands, creating the entry / exit section 52a of the binding tool 5 (forming a gap). The edge 61c of the elongated hole in the bound object 2 is inserted into the entry / exit section 52a of the outer portion 56a. As a result, the edge 61c of the elongated hole in the bound object 2 is retracted within the double-tube structure of the binding tool 5. Positioning is adjusted so that the discontinuous portion 54a of the outer portion 56a is located opposite the discontinuous portion 54b of the inner portion 56b.

[0087] Next, the process of removing the binding tool 5 from the file folder 1 will be described. The binding tool 5 deforms. Specifically, the discontinuous portion 54a of the outer portion 56a expands, and the edge portion 61c of the long hole of the bound object 2 is removed from the inlet and outlet portion 52a of the outer portion 56a. Subsequently, the discontinuous portion 54b of the inner portion 56b expands, and the edge portion 61c of the long hole of the bound object 2 is removed from the inlet and outlet portion 52b of the inner portion 56b.

[0088] <Effect> The binding tool 5 of the file folder 1 equipped with the binding tool 5 of the eighth embodiment is made of a deformable resin and includes discontinuous portions 54 (54a, 54b) and insertion and removal portions 52 (52a, 52b), allowing for free replacement of the bound object 2. The binding tool 5 of the eighth embodiment allows for replacement of the bound object 2 simply by expanding the discontinuous portions 54 of the outer and inner portions 56a, 56b. Furthermore, the binding tool 5 has a double-tube structure, enabling more stable binding of the bound object 2. Furthermore, by positioning the discontinuous portion 54a of the outer portion 56a opposite the discontinuous portion 54b of the inner portion 56b, the binding tool 5 is less likely to fall off. Furthermore, the binding tool 5 of the eighth embodiment, made of a deformable resin, does not cause pressure on the hand, making writing easier.

[0089] While the embodiments of the present invention have been described above, the above embodiments and other embodiments can be appropriately modified without departing from the spirit of the present invention. Description of reference numerals:
