The first section S1 to the third section S3 are arranged at equal intervals of 120 degrees as viewed from above. The position of the third section S3 is at the position of the center line FF in the width direction of the binding tool 10. In addition, the area divided in the circumferential direction of the outer peripheral surface of the binding pin 22 is not limited to three, and may be two or four or more.

A small circumferential surface 30a (diameter is the same φ2 mm as the first small circumferential surface 28a), an inclined surface 31a, and a large circumferential surface 32a (φ3 mm) having a large diameter are connected. The first protrusions 27a and the second protrusions 29a extend in a direction parallel to the contact surface 20a of the first binding plate 20 on the outer peripheral surface of the first section S1.

  In the height direction of the binding pin 22, the large circumferential surface 32 a is disposed to a height of 1.8 mm from the contact surface 20 a of the first binding plate 20.

The 2nd protrusion part 29a is arrange | positioned by the height of 2.7-3.3 mm. The first small circumferential surface 28a is disposed at a height of 3.3 to 3.6 mm. The first protrusion 27a is disposed at a height of 3.6 to 4.2 mm.

  Therefore, the binding pin 22 has two steps different in position in the height direction, which are formed by the first protrusion 27a and the second protrusion 29a in the first section S1. become. Then, the two steps formed by the first and second protrusions 27a and 29a are engaged with a receiving part 50a of the binding rod insertion hole 14 described later.

  As shown in FIG. 5, the outer peripheral surface of the second section S2 also has an arcuate first protrusion 27b (protrusion of the protrusion) having a medium diameter from the head 23a of the binding pin 22 toward the root 23b. The first small circumferential surface 28b (φ2 mm) having a small diameter and a second arc-shaped second protrusion 29b having a medium diameter (diameter is the same as the first protrusion 27b φ2.6 mm). ), A second small circumferential surface 30b having a small diameter (diameter is the same φ2 mm as the first small circumferential surface 28b), an inclined surface 31b, and a large circumferential surface 32b having a large diameter (φ3 mm) are connected. The first protrusions 27b and the second protrusions 29b extend in a direction parallel to the contact surface 20a of the first binding plate 20 on the outer peripheral surface of the second section S2.

  In the height direction of the binding pin 22, the large circumferential surface 32 b is disposed from the contact surface 20 a of the first binding plate 20 to a height of 1.5 mm. The inclined surface 31b is disposed at a height of 1.5 to 2.1 mm. The second small circumferential surface 30b is disposed at a height of 2.1 to 2.4 mm. The second protrusion 29b is disposed at a height of 2.4 to 3.0 mm. The first small circumferential surface 28b is disposed at a height of 3.0 to 3.3 mm. The first protrusion 27b is disposed at a height of 3.3 to 3.9 mm.

  Therefore, the binding pin 22 has two steps different in position in the height direction, which are formed by the first protrusion 27b and the second protrusion 29b in the second section S2. Become. Then, the two steps formed by the first and second protrusions 27b and 29b are engaged with a receiving part 50b of the binding rod insertion hole 14 described later.

  On the outer peripheral surface of the third section S3, the first protruding portion 27c having a medium diameter from the head portion 23a of the binding pin 22 toward the root portion 23b (φ2.6 mm at the outermost periphery of the protruding portion). ), A first flat surface 28c separated from the central axis of the binding pin 22 by a predetermined distance (1 mm), and a second arc-shaped second protrusion 29c having a medium diameter (the diameter is the same as that of the sixth protrusion 27c φ2. 6 mm), a second plane 30c (a distance from the center axis of the binding pin 22 is the same as the first plane 28c), a predetermined distance (1 mm) away from the central axis of the binding pin 22, an inclined surface 31c, and a large diameter The large circumferential surface 32c (φ3 mm) is connected. The first protrusions 27c and the second protrusions 29c extend in a direction parallel to the contact surface 20a of the first binding plate 20 on the outer peripheral surface of the third section S3. The first plane 28c and the second plane 30c are planes orthogonal to the center line FF, respectively. The surface 28c and the surface 30c are flat so as to be in contact with a third receiving portion 50c of a later-described binding rod insertion hole 42 so as to be easily inserted into the binding rod insertion hole 42. For example, it may be a small circumferential surface similar to the first small circumferential surface 28a.

  In the height direction of the binding pin 22, the large circumferential surface 32 c is disposed to a height of 1.0 mm from the contact surface 20 a of the first binding plate 20. The inclined surface 31c is disposed at a height of 1.0 to 1.8 mm. The second plane 30c is disposed at a height of 1.8 to 2.1 mm. The second protrusion 29c is disposed at a height of 2.1 to 2.7 mm. The first plane 28c is disposed at a height of 2.7 to 3.0 mm. The first protrusion 27c is disposed at a height of 3.0 to 3.6 mm.

  Therefore, the binding pin 22 has two steps different in position in the height direction, which are formed by the first protrusion 27c and the second protrusion 29c in the third section S3. Become. Then, the two steps formed by the first and second protrusions 27c and 29c are engaged with a receiving part 50c of the binding rod insertion hole 14, which will be described later.

As a result, in the binding pin 22 as a whole, six steps that are formed by the six protrusions of the first protrusions 27a to 27c and the second protrusions 29a to 29c and have different positions in the height direction. Will have.
As shown in Table 1, the first protrusions 27 a to 27 c and the second protrusions 29 a to 29 c are arranged at a pitch of 0.3 mm in the height direction of the binding pin 22. Accordingly, the six steps formed by the first protrusions 27 a to 27 c and the second protrusions 29 a to 29 c are arranged at a pitch of 0.3 mm in the height direction of the binding pin 22. That is, the binding tool 10 starts from the step formed on the side near the head 23a of the binding pin 22 (first protrusion 27b) from the step formed by the first protrusion 27b. The step formed by the portion 27a, the step formed by the first ridge 27c, the step formed by the second ridge 29b, the step formed by the second ridge 29a, and the base 23b that is the end. In order to the level difference (second protrusion portion 29c) on the side, it has a structure having six stages of locking positions at a pitch of 0.3 mm in the height direction of the binding pin 22, and the thickness of the binding object P is increased. In total, it can be finely adjusted one step at a time. Here, for example, in the height direction of the binding pin 22, the distance from the step formed by the first protrusion 27 b to the step formed by the adjacent first protrusion 27 a is 1 with a pitch of 0.3 mm. It is a unit.

Each of the first protrusions 27 a to 27 c and the second protrusions 29 a to 29 c has a surface 35 (see FIG. 4) in the direction of insertion in the binding insertion hole 42 described later on the binding insertion hole 42. It has an inclined surface for easy insertion.
On the other hand, the surface 36 of each of the first protrusions 27a to 27c and the second protrusions 29a to 29c on the side opposite to the direction in which the first protrusions 27a to 27c are inserted into the binding insertion holes 42 is a binding insertion hole 42 described later. The first receiving portion 50a to the third receiving portion 50c are parallel to the contact surface 20a of the first binding plate 20 so that the first receiving portion 50a to the third receiving portion 50c are easily caught. That is, each position of the surface 36 becomes a locking position with any one of the first receiving portion 50a to the third receiving portion 50c. The shapes of the first protrusions 27a to 27c and the second protrusions 29a to 29c are arbitrary, and if they are caught by the first receiving part 50a to the third receiving part 50c of the binding rod insertion hole 42, the shapes thereof are It doesn't matter.
FIG. 10 is an explanatory diagram showing the positional relationship in the height direction of the first section S1 to the third section S3 of the binding pin 22. As shown in FIG. 10, the first ridges 27 a to 27 c and the second ridges 29 a to 29 c forming the step are such that the ridges adjacent in the height direction of the binding pin 22 are shifted in a step shape. It is formed and is intermittently formed in the circumferential direction of the binding pin 22 at different height positions in the height direction of the binding pin 22 for each of the first section S1 to the third section S3. The six ridges of the first ridges 27a to 27c and the second ridges 29a to 29c are connected to the root portion from the first ridge 27b at the start end of the binding pin 22 near the head 23a. The second protrusion 29c is located on the side close to 23b, and the second protrusion 29c is gradually turned counterclockwise in the circumferential direction of the binding pin 22 so as to have substantially two turns. In other words, after the first protrusions 27a to 27c of the first section S1 to the third section S3 have made approximately one turn while descending stepwise counterclockwise in the circumferential direction of the binding pin 22, the first section The second ridges 29a to 29c in the S1 to the third section S3 have a structure in which they make one round while descending stepwise counterclockwise in the circumferential direction of the binding pin 22.

For example, the cross section of the binding pin 22 at a height of 3.0 mm from the contact surface 20a of the first binding plate 20 has a shape as shown in FIG. 11 is a cross-sectional view taken along the line GG in FIG. At this position, the second protrusion 29a is disposed.
Further, for example, the cross section of the binding pin 22 at a height of 2.4 mm from the contact surface 20a of the first binding plate 20 has a shape as shown in FIG. 12 is a cross-sectional view taken along line HH in FIG. The second protrusion 29c is arranged at this position.

  Furthermore, a binding pin 22 is provided at a substantially central portion of the lower surface of the first binding plate 20 (which is an outer surface in the state where the object to be bound is bound to the binding tool 10 and hereinafter referred to as an outer surface) 20b. A semicircular arc-shaped recess 38 is formed at a position corresponding to the position where the is erected. When binding an object to be bound, a force can be effectively transmitted to the binding pin 22 by applying a force to this position.

(2) Binding rod insertion hole portion The binding rod insertion hole portion 14 has a substantially rectangular second binding plate 40 and one circular binding rod insertion hole 42 provided at a substantially central portion of the second binding plate 40. doing. The binding pin insertion hole 42 is disposed at a position symmetrical to the position of the binding pin 22 with respect to the center line DD in the length direction of the binding tool 10. The binding pin insertion hole 42 is used for binding the binding object together with the binding pin 22 through the binding pin 22.

  The second binding plate 40 has an upper surface in a state in which the binding tool 10 has bound the object to be bound (a surface on which the object to be bound abuts in a state in which the object to be bound is bound to the binding tool 10). 40a (referred to as a contact surface) is in a positional relationship facing the contact surface 20a of the first binding plate 20 of the binding pin portion 12. An abutting surface 40a of the second binding plate 40 is provided with an annular groove 44 having a U-shaped cross section at a predetermined distance outside the binding insertion hole 42. The contact surface 40a of the second binding plate 40 is a smooth surface because the object to be bound contacts.

In the binding insertion hole 42, a first slit hole having a wide width from a position corresponding to the first boundary portion 24 to the third boundary portion 26 of the first section S1 to the third section S3 that is divided at equal intervals on the binding pin 22. 45, the second slit hole 46, and the third slit hole 47 extend radially in three directions at equal intervals of 120 degrees in a plan view from above, and the tips thereof reach the outer peripheral inner wall of the groove 44. The position of the 1st slit hole 45 exists in the position of the center line FF of the width direction of the binding tool 10, and the 1st slit hole 45-the 3rd slit hole 47 are line symmetrical positions with respect to the center line FF. It has become a relationship. The first slit hole 45 to the third slit hole 47 are arranged so that their tips are farthest from the edge of the second binding plate 40. By separating the tips of the first slit hole 45 to the third slit hole 47 from the edge of the second binding plate 40, the second binding plate 40 is difficult to cut.

  When binding the object to be bound, the first boundary portion 24 of the binding pin 22 is inserted into the first slit hole 45. The second boundary portion 25 is inserted into the second slit hole 46. The third boundary portion 26 is inserted into the third slit hole 47. Therefore, the slit widths of the first slit hole 45 to the third slit hole 47 are set larger than the widths of the first boundary part 24 to the third boundary part 26.

  The groove 44 and the first slit hole 45 to the third slit hole 47 cooperate with each other with a force applied when the binding pin 22 is pushed into the binding insertion hole 42 when binding the object to be bound. It can be dispersed throughout the binding plate 40 to relieve mechanical stress.

The diameter of the circular binding pin insertion hole 42 at the contact surface 40a of the second binding plate 40 is larger than the diameter (φ3 mm) of the binding pin 22 (φ3.2 mm) so that the binding pin 22 can be easily inserted. The inner circumferential wall surface of the circular binding rod insertion hole 42 is divided into three parts at intervals in the circumferential direction of the binding rod insertion hole 42 around the center of the binding rod insertion hole 42. A first receiving portion 50a, a second receiving portion 50b, and a third receiving portion 50c to be locked are formed. The position of the third receiving portion 50c is at the position of the center line FF in the width direction of the binding tool 10, and the first receiving portion 50a to the third receiving portion 50c are line-symmetric with respect to the center line FF. It is a positional relationship.
Each of the first receiving portion 50a to the third receiving portion 50c is second bound so that the surface 51 (see FIG. 13) in the direction in which the binding pin 22 is inserted can be easily inserted. The diameter of the binding pin insertion hole 42 is inclined to decrease from the contact surface 40a of the plate 40 toward the back of the binding pin insertion hole 42, and the minimum diameter is the maximum diameter of the binding pin 22 ( smaller than φ3 mm) (φ2.2 mm).

On the other hand, the surface 52 of each of the first receiving portion 50a to the third receiving portion 50c opposite to the direction in which the binding pin 22 is inserted is the first protrusions 27a to 27c of the binding pin 22. And it is a plane parallel to the contact surface 40a of the 2nd binding board 40 so that the 2nd protrusion part 29a-29c may be easily caught. That is, each position of the surface 52 becomes a locking position with any one of the protrusions 27a to 27c and 29a to 29c. And each surface 52 of the 1st receiving part 50a-the 3rd receiving part 50c exists in the same position in the direction in which the binding pin 22 is inserted.
However, the 1st receiving part 50a-the 3rd receiving part 50c have elasticity, and when it latches to the binding pin 22, the height position of the 1st receiving part 50a-the 3rd receiving part 50c changes. . That is, the first receiving portion 50 a to the third receiving portion 50 c are locked to the binding pin 22 by elastic force, and the binding pin 22 is closely fitted in the binding pin insertion hole 42.
The diameter of the binding pin insertion hole 42 at the lower surface 40b of the second binding plate 40 (which is an outer surface in the state in which the object to be bound is bound to the binding tool 10, hereinafter referred to as the outer surface) is the binding pin. 22 is the same as the maximum diameter (φ3 mm). In addition, the shape of the 1st receiving part 50a-the 3rd receiving part 50c is arbitrary, The shape will be used if it hooks on the 1st protrusion part 27a-27c and the 2nd protrusion part 29a-29c of the binding pin 22 Does not matter.

(3) Connection part The connection part 16 is arrange | positioned between the binding pin part 12 and the binding pin insertion hole part 14. As shown in FIG. The upper surface 16a of the rectangular connecting portion 16 (the surface to be bound comes into contact with the binding object 10 in a state where the binding object is bound to the binding tool 10, and hereinafter referred to as a contact surface) 16a is the end of the binding object. It is a smooth surface to touch. The contact surface 16a is located at a position retracted from the contact surface 20a of the first binding plate 20 of the binding pin portion 12 and the contact surface 40a of the second binding plate 40 of the binding pin insertion hole 14. Therefore, when the binding tool 10 is bent inward in the length direction of the binding tool 10 by the hinge parts 18 and 19, the connecting part 16 can be prevented from colliding with the binding pin part 12 and the binding hole insertion hole 14. .

  On the other hand, the lower surface of the connecting portion 16 (which is a surface that is an outer surface when the object to be bound is bound to the binding tool 10 and is hereinafter referred to as an outer surface) 16b is curved downward and swells. The contact surface 20a of the first binding plate 20 and the contact surface 40a of the second binding plate 40 are substantially flush with each other.

(4) Hinge portion The first hinge portion 18 is for connecting the binding pin portion 12 and the connecting portion 16 and is disposed between the binding pin portion 12 and the connecting portion 16 so as to be freely bent. Yes. The second hinge portion 19 is for connecting the binding rod insertion hole portion 14 and the connecting portion 16, and is disposed between the binding rod insertion hole portion 14 and the connecting portion 16 so as to be freely bent. The hinge portions 18 and 19 extend in the width direction of the binding tool 10 and can be bent in the length direction thereof. In addition, the shape of the hinge parts 18 and 19 is arbitrary, for example, the hinge width may be narrow and the hinge thickness may be thin.

R-shaped concave portions 18a, 18b, 19a, 19b are formed at both ends of the hinge portions 18, 19, so that the hinge portions 18, 19 are difficult to break.
In addition, the hinge parts 18 and 19 and the connection part 16 are not necessarily required, and one of them may be configured to have the other function.

2. FIG. 14 is a perspective view for explaining a binding method using the binding tool 10 according to the first embodiment. FIG. 15 is a partial cross-sectional view of the binding tool 10 shown in FIG. FIG. 16 is a plan view of the binding tool 1 shown in FIG.

The binding tool 10 before binding is in a plate-like state as shown in FIG.
First, the binding object P is inserted from the left side to the right side, the binding hole Pa of the binding object P is passed through the binding pin 22 of the binding tool 10, and the contact surface 20 a of the binding pin part 12. One to a plurality of objects to be bound P are placed on the sheet.

  Next, in the binding tool 10, the binding pin insertion hole 14 is positioned at the position of the hinge portion 19 so that the second binding plate 40 of the binding pin insertion hole 14 faces the first binding plate 20 of the binding pin portion 12. In addition, the connecting portion 16 is bent at a substantially right angle inside the longitudinal direction of the binding tool 10 at the position of the hinge portion 18, and the binding pin 22 is strongly pushed into the binding pin insertion hole 42 from above. Inserted and transformed into an inverted U shape. And any one of the first protrusions 27a to 27c and the second protrusions 29a to 29c of the binding pin 22 is any of the first receiving part 50a to the third receiving part 50c of the binding pin insertion hole 42. By being locked, the object P is bound.

  For example, FIG. 17 is a cross-sectional view taken along the line I1-I1 of FIG. 16 when 20 sheets of the binding object P are bound. 18 is a cross-sectional view taken along the line I2-I2 of FIG. 16 when 20 sheets of paper P are bound. 19 is a cross-sectional view taken along the line I3-I3 of FIG. 16 when 20 sheets of paper P are bound.

  17 to 19, when 20 sheets P are bound by the binding tool 10, the first receiving portion 50a of the binding pin insertion hole 42 and the first protrusion 27a of the binding pin 22 are locked. In addition, the third receiving portion 50c and the first protruding portion 27c are locked, and further, the second receiving portion 50b and the first protruding portion 27b are locked, thereby being bound. I understand.

  20 is a cross-sectional view taken along line I1-I1 of FIG. 16 when twelve sheets of paper P are bound. From FIG. 20, when 12 sheets P are bound by the binding tool 10, the first receiving portion 50 a of the binding pin insertion hole 42 and the second protruding portion 29 a of the binding pin 22 are locked. You can see that it is bound.

  FIG. 21 is a cross-sectional view taken along the line I3-I3 of FIG. 16 when five sheets of paper P are bound. From FIG. 21, when five sheets P are bound by the binding tool 10, the second receiving portion 50b of the binding pin insertion hole 42 and the second protrusion 29b of the binding pin 22 are locked, and It can be seen that the third receiving portion 50c and the second projecting ridge portion 29c are bound together to be bound.

3. Binding Tool of Second Embodiment FIG. 22 is a plan view showing the binding tool 110 of the second embodiment in a state before binding sheets. FIG. 23 is a cross-sectional view of the binding tool 110.
The binding rod insertion hole 142 of the binding tool 110 according to the second embodiment is formed with receiving portions 150a and 150b at intervals in the circumferential direction of the inner wall surface of the binding device, and the positions of the receiving portions 150a and 150b are inserted into the binding rod. It differs in the depth direction of the hole 142.

The binding tool 110 includes a binding pin portion 112, a binding pin insertion portion 114, a connecting portion 116, a first hinge portion 118, and a second hinge portion 119, which are connected in this order. The binding pin portion 112, the binding pin insertion hole 114, the connecting portion 116, the first hinge portion 118, and the second hinge portion 119 are integral, and have elasticity and a certain degree of rigidity. For example, it is made of polypropylene resin. Therefore, the binding tool 110 has a simple structure, a light weight, and an inexpensive binding tool.
In the state after binding the object to be bound, the binding tool 110 has a length direction of the binding tool 110 such that the binding pin portion 112 and the binding rod insertion hole 114 face each other as shown in FIG. It is bent and deformed inside, and is in a substantially inverted U shape. Hereinafter, as shown in FIG. 14, the “upper side”, “lower side”, “left side”, and “right side (insertion direction of the object to be bound)” in the specification include the binding tool 110 and the binding pin portion 112. Is the lower side and the binding rod insertion hole 114 is the upper side, and means the direction in the state after binding the objects to be bound.
In the second embodiment, the binding tool 110 having one binding pin 122 and one binding pin insertion hole 142 corresponding to the binding pin 122 will be described. However, the present invention is not limited to this. The binding tool which has the binding pin 122 and the binding pin insertion hole 142 may be sufficient.

(1) Binding pin portion The binding pin portion 112 includes a substantially rectangular first binding plate 120 and an upper surface of the first binding plate 120 (when the binding target is bound to the binding tool 110, the binding target is And a binding pin 122 provided at a substantially central portion of 120a). The contact surface 120a of the first binding plate 120 is a smooth surface because the object to be bound contacts.

  The binding pin 122 has a curved head 123a so that it can be easily inserted into the binding pin insertion hole 142 described later. The binding pin 122 has an uneven outer periphery, and thus has a plurality of steps. In the case of the second embodiment, the binding pin 122 has a maximum diameter of 3 mm and a length of 4.2 mm. The maximum diameter of the binding pin 122 is set to a dimension equal to the diameter of the binding hole of the object to be bound since it is generally φ3 mm.

  On the outer peripheral surface of the binding pin 122, a ring-shaped first protrusion 127 having a medium diameter from the head 123a toward the root 123b (φ2.6 mm at the outermost periphery of the protrusion), the diameter is small. A first small circumferential surface 128 (φ2 mm), a ring-shaped second ridge 129 (diameter is the same as the first ridge 127), and a second small circumferential surface with a small diameter. 130 (diameter is the same φ2 mm as the first small circumferential surface 128), an inclined surface 131, and a large circumferential surface 132 (φ3 mm) having a large diameter are connected. The first protrusion 127 and the second protrusion 129 extend around the binding pin 122 in a direction parallel to the contact surface 120 a of the first binding plate 120.

  For example, in the height direction of the binding pin 122, the large circumferential surface 132 is disposed to a height of 1.8 mm from the contact surface 120 a of the first binding plate 120. The inclined surface 131 is disposed at a height of 1.8 to 2.4 mm. The second small circumferential surface 130 is disposed at a height of 2.4 to 2.7 mm. The second protrusion 129 is disposed at a height of 2.7 to 3.3 mm. The first small circumferential surface 128 is disposed at a height of 3.3 to 3.6 mm. The first protrusion 127 is disposed at a height of 3.6 to 4.2 mm.

  Therefore, the binding pin 122 has, on the outer peripheral surface, two steps formed by the first protrusion 127 and the second protrusion 129 and having different positions in the height direction. . The two steps formed by the first protrusion 127 and the second protrusion 129 are locked with any one of receiving portions 150a and 150b of the binding pin insertion hole 114 described later. become.

  In the height direction of the binding pin 122, the distance from the step formed by the first ridge 127 to the step formed by the adjacent second ridge 129 is 0.9 mm. That is, the binding tool 110 has a step (second protrusion) on the side close to the root portion 123b that is the end when the step (first protrusion 127) on the side close to the head 123a of the binding pin 122 is used as a start end. In order to the portion 129), there are two stages of locking positions at a 0.9 mm pitch in the height direction of the binding pin 122.

Each of the first protrusion 127 and the second protrusion 129 has a surface 135 (see FIG. 23) on the side in which the first protrusion 127 and the second protrusion 129 are inserted into the binding insertion hole 142 described later, so that the insertion is easy. It has an inclined surface.
On the other hand, the surface 136 of each of the first protrusion 127 and the second protrusion 129 opposite to the side in the direction of insertion into the binding insertion hole 42 is a first receiving portion of the binding insertion hole 142 described later. The flat surface is parallel to the contact surface 120a of the first binding plate 120 so that the portion 150a and the second receiving portion 150b can be easily caught. That is, each position of the surface 136 becomes a locking position with one of the first receiving portion 150a and the second receiving portion 150b. The shape of the 1st protrusion 127 and the 2nd protrusion 129 is arbitrary, and the shape will not be ask | required if it catches in the 1st receiving part 150a and the 2nd receiving part 150b of the binding pin insertion hole 142. FIG.

  Furthermore, a binding pin 122 is provided at a substantially central portion of the lower surface of the first binding plate 120 (which is an outer surface when the object to be bound is bound to the binding tool 110, hereinafter referred to as an outer surface) 120b. A semicircular arc-shaped recess 138 is formed at a position corresponding to the position where the is erected. When binding an object to be bound, a force can be effectively transmitted to the binding pin 122 by applying a force to this position.

(2) Binding rod insertion hole portion The binding rod insertion hole portion 114 has a substantially rectangular second binding plate 140 and one circular binding rod insertion hole 142 provided at a substantially central portion of the second binding plate 140. doing. The binding pin insertion hole 142 is disposed at a position symmetrical to the position of the binding pin 122 with respect to the center line DD in the length direction of the binding tool 110. The binding pin insertion hole 142 is used for binding the binding object together with the binding pin 122 through which the binding pin 122 is inserted.

  The second binding plate 140 has an upper surface in a state in which the binding tool 110 has bound the object to be bound (a surface on which the object to be bound abuts in a state in which the object to be bound is bound to the binding tool 110). 140a (referred to as a contact surface) is in a positional relationship facing the contact surface 120a of the first binding plate 120 of the binding pin portion 112. The contact surface 140a of the second binding plate 140 is a smooth surface because the object to be bound contacts.

  Unlike the binding tool 10 of the first embodiment, the binding tool 110 of the second embodiment places a predetermined distance on the contact surface 140a of the second binding plate 140 outside the binding hole insertion hole 142. In addition, an annular groove having a U-shaped cross section is not provided. Further, from the binding insertion hole 142, the wide first slit hole, second slit hole and third slit hole are not provided. However, the binding pin 122 is inserted into the binding pin when an annular groove or first to third slit holes are provided and the object to be bound is bound by the grooves and the first to third slit holes. Needless to say, the force applied when being pushed into the hole 142 may be cooperatively distributed throughout the second binding plate 140 to relieve mechanical stress.

The diameter of the circular binding pin insertion hole 142 at the contact surface 140a of the second binding plate 140 is larger than the diameter (φ3 mm) of the binding pin 122 (φ3.2 mm) so that the binding pin 122 can be easily inserted. The inner surface of the circular binding rod insertion hole 142 is engaged with the binding pin 122 at an interval of 180 degrees in the circumferential direction of the binding insertion hole 142 with the center of the binding insertion hole 142 as the center. A first receiving part 150a and a second receiving part 150b are formed. The first receiving portion 150a and the second receiving portion 150b face each other at the position of the center line FF in the width direction of the binding tool 110, and the first receiving portion 150a and the second receiving portion 150b are in the center line F-. It is line symmetric with respect to F. In addition, the receiving part provided in the circumferential direction of the inner peripheral wall surface of the binding insertion hole 142 is not limited to two, and may be three or more.
Each of the first receiving portion 150a and the second receiving portion 150b is arranged so that the surfaces 151a and 151b (see FIG. 23) on the side in which the binding pin 122 is inserted can be inserted easily. As the diameter of the binding pin insertion hole 142 decreases from the contact surface 140a of the two binding plates 140 toward the back of the binding pin insertion hole 142, the minimum diameter is the maximum of the binding pin 122. It is smaller than the diameter (φ3 mm) (φ2.2 mm).

On the other hand, the surfaces 152a and 152b of the first receiving part 150a and the second receiving part 150b opposite to the side in which the binding pin 122 is inserted are the first protrusions 127 of the binding pin 122, respectively. And it becomes a plane parallel to the contact surface 140a of the 2nd binding board 140 so that the 2nd protrusion part 129 may be caught easily. That is, each position of the surfaces 152a and 152b is a locking position with any one of the protrusions 127 and 129.
The position of the surface 152a of the first receiving portion 150a and the position of the surface 152b of the second receiving portion 150b are different in the depth direction of the binding pin insertion hole 142. Here, the distance (pitch) between the position of the surface 152a and the surface 152b adjacent in the depth direction of the binding pin insertion hole 142 is the same as that of the first protrusion 127 adjacent in the height direction of the binding pin 122. It is set to be smaller than the distance (pitch) from the second protrusion 129.
Therefore, when the binding tool 110 binds the object to be bound, when the binding pin 122 is inserted into the binding pin insertion hole 142, first, the surface 152 a of the first receiving portion 150 a causes the first protrusion of the binding pin 122. Next, the surface 152 b of the second receiving portion 150 b is hooked on the first protrusion 127 of the binding pin 122. Further, when the binding pin 122 is inserted into the binding pin insertion hole 142, the surface 152a of the first receiving portion 150a is hooked on the second protrusion 129 of the binding pin 122, and then the second receiving portion 150b. The surface 152b is hooked on the second protrusion 129 of the binding pin 122. That is, according to the depth at which the binding pin 122 is inserted into the binding pin insertion hole 142, either the protrusion 127 or 129 of the binding pin 122 is either the receiving portion 150 a or 150 b of the binding pin insertion hole 142. The insertion depth of the binding pin 122 into the binding pin insertion hole 142 is adjusted in order.
As a result, the binding tool 110 has a structure having four stages of locking positions, and can be finely adjusted step by step in accordance with the thickness of the binding object P.
However, the 1st receiving part 150a and the 2nd receiving part 150b have elasticity, and when it latches to the binding pin 122, the height position of the 1st receiving part 150a and the 2nd receiving part 150b changes. . That is, the first receiving portion 150 a and the second receiving portion 150 b are locked to the binding pin 122 by elastic force, and the binding pin 122 is closely fitted in the binding pin insertion hole 142.
The diameter of the binding pin insertion hole 142 on the lower surface of the second binding plate 140 (the surface that is the outer side when the binding target is bound to the binding tool 110, hereinafter referred to as the outer surface) 140b is the binding pin. This is the same as the maximum diameter of 122 (φ3 mm). In addition, the shape of the 1st receiving part 150a and the 2nd receiving part 150b is arbitrary, The shape will not be ask | required if it hooks on the 1st protrusion part 127 and the 2nd protrusion part 129 of the binding pin 122. FIG.

(3) Connection part The connection part 116 is arrange | positioned between the binding pin part 112 and the binding pin insertion hole part 114. FIG. An upper surface 116a of the rectangular connecting portion 116 (in a state where the object to be bound is bound to the binding tool 110 is a surface on which the object to be bound comes into contact, hereinafter referred to as a contact surface) 116a is an end of the object to be bound. It is a smooth surface to touch. The contact surface 116a is in a position retracted from the contact surface 120a of the first binding plate 120 of the binding pin portion 112 and the contact surface 140a of the second binding plate 140 of the binding rod insertion hole 114. Therefore, when the binding tool 110 is bent inward in the longitudinal direction of the binding tool 110 by the hinge portions 118 and 119, the connecting portion 116 can be prevented from colliding with the binding pin portion 112 and the binding pin insertion hole 114. .

  On the other hand, a lower surface 116b of the connecting portion 116 (which is an outer surface when the object to be bound is bound to the binding tool 110, hereinafter referred to as an outer surface) 116b is curved downward and swells. The contact surface 120a of the first binding plate 120 and the contact surface 140a of the second binding plate 140 are substantially flush with each other.

(4) Hinge portion The first hinge portion 118 is for connecting the binding pin portion 112 and the connecting portion 116, and is disposed between the binding pin portion 112 and the connecting portion 116 so as to be freely bent. Yes. The second hinge portion 119 is for connecting the binding rod insertion hole portion 114 and the connecting portion 116, and is disposed between the binding rod insertion hole portion 114 and the connecting portion 116 so as to be freely bent. The hinge portions 118 and 119 extend in the width direction of the binding tool 110, and the binding tool 110 can be bent in the length direction thereof. In addition, the shape of hinge part 118,119 is arbitrary, For example, a hinge width | variety may be narrow and a hinge thickness may be thin.

  Note that the hinge portions 118 and 119 and the connecting portion 116 are not necessarily required, and any one of them may have a function of the other.

4). The binding tool of 3rd Embodiment The binding tool of 3rd Embodiment is the binding tool 10 of 1st Embodiment shown in FIGS. The first embodiment except that the positions of the first receiving portion 50a, the second receiving portion 50b, and the third receiving portion 50c formed on the inner peripheral wall surface are different in the depth direction of the binding pin insertion hole 42. It is substantially the same as the binding tool 10 of the form. Therefore, the binding tool of the third embodiment will be described with reference to (appropriate) FIGS. 1 to 13 of the first embodiment. In the following description, the same parts and the same parts will be described using the same reference numerals.

Therefore, the binding tool of the third embodiment is a simple structure, a light weight, and an inexpensive binding tool.
As shown in FIG. 14, the binding tool of the third embodiment is in a state after binding the binding object so that the binding pin portion 12 and the binding insertion hole 14 face each other. It is bent and deformed inward in the length direction to be in a substantially inverted U-shaped state. Hereinafter, as shown in FIG. 14, the “upper side”, “lower side”, “left side”, and “right side (insertion direction of the object to be bound)” in the specification indicate that the binding tool includes the binding pin portion 12. On the lower side, the binding rod insertion hole 14 is on the upper side, and the direction in a state after binding the objects to be bound is meant.
In the third embodiment, a binding tool having one binding pin 22 and one binding pin insertion hole 42 corresponding to the binding pin 22 is described. However, the present invention is not limited to this. The binding tool which has the scissors pin 22 and the binding pin insertion hole 42 may be sufficient.

(1) Binding pin portion The binding pin portion 12 includes a substantially rectangular first binding plate 20 and an upper surface of the first binding plate 20 (in a state where the object to be bound is bound by the binding tool of the third embodiment). And a binding pin 22 provided at a substantially central portion of the surface 20a). The contact surface 20a of the first binding plate 20 is a smooth surface because the object to be bound contacts.

  The binding pin 22 has a curved half on the right side (the side on which the first hinge portion 18 is provided) and a half on the left side (the side opposite to the side on which the first hinge portion 18 is provided). Is an inclined surface so that it can be easily inserted into a binding pin insertion hole 42 described later. This binding pin 22 has an uneven outer periphery, and therefore has a plurality of steps. In the case of the binding tool according to the third embodiment, the binding pin 22 has a maximum diameter of 3 mm and a length of 4.2 mm. The maximum diameter of the binding pin 22 is set to a size equal to the diameter of the binding hole of the object to be bound since it is generally φ3 mm.

In order to divide the outer peripheral surface of the binding pin 22, the first boundary portion 24, the second boundary portion 25, and the third boundary portion 26 are spaced apart from each other in the circumferential direction about the axis line.

  The relationship between the height from the contact surface 20a of the first binding plate 20 and the step on the outer periphery of the binding pin 22 is as shown in Table 1 above.

The outer peripheral surface of the binding pin 22 is formed by the first boundary portion 24 to the third boundary portion 26, the first section S 1 between the first boundary portion 24 and the second boundary portion 25, the first boundary portion 24, and the first boundary portion 24. It is partitioned into a second section S2 between the third boundary section 26 and a third section S3 between the second boundary section 25 and the third boundary section 26. The first section S1 to the third section S3 are arranged at equal intervals of 120 degrees as viewed from above. The position of 3rd area S3 exists in the position of the centerline FF of the width direction of the binding tool of 3rd Embodiment. In addition, the area divided in the circumferential direction of the outer peripheral surface of the binding pin 22 is not limited to three, and may be two or four or more.
On the outer peripheral surface of the first section S1, an arc-shaped first protrusion 27a having a medium diameter from the head 23a of the binding pin 22 toward the root 23b (φ2.6 mm at the outermost periphery of the protrusion). ), A first small circumferential surface 28a (φ2 mm) having a small diameter, an arc-shaped second protrusion 29a (the diameter is the same as the first protrusion 27a φ2.6 mm), and a small diameter 2. A small circumferential surface 30a (diameter is the same φ2 mm as the first small circumferential surface 28a), an inclined surface 31a, and a large circumferential surface 32a (φ3 mm) having a large diameter are connected. The first protrusions 27a and the second protrusions 29a extend in a direction parallel to the contact surface 20a of the first binding plate 20 on the outer peripheral surface of the first section S1.

  In the height direction of the binding pin 22, the large circumferential surface 32 a is disposed to a height of 1.8 mm from the contact surface 20 a of the first binding plate 20. The inclined surface 31a is disposed at a height of 1.8 to 2.4 mm. The second small circumferential surface 30a is disposed at a height of 2.4 to 2.7 mm. The 2nd protrusion part 29a is arrange | positioned by the height of 2.7-3.3 mm. The first small circumferential surface 28a is disposed at a height of 3.3 to 3.6 mm. The first protrusion 27a is disposed at a height of 3.6 to 4.2 mm.

  Therefore, the binding pin 22 has two steps different in position in the height direction, which are formed by the first protrusion 27a and the second protrusion 29a in the first section S1. become. Then, the two steps formed by the first and second protrusions 27a and 29a are engaged with a receiving part 50a of the binding rod insertion hole 14 described later.

  As shown in FIG. 5, the outer peripheral surface of the second section S2 also has an arcuate first protrusion 27b (protrusion of the protrusion) having a medium diameter from the head 23a of the binding pin 22 toward the root 23b. The first small circumferential surface 28b (φ2 mm) having a small diameter and a second arc-shaped second protrusion 29b having a medium diameter (diameter is the same as the first protrusion 27b φ2.6 mm). ), A second small circumferential surface 30b having a small diameter (diameter is the same φ2 mm as the first small circumferential surface 28b), an inclined surface 31b, and a large circumferential surface 32b having a large diameter (φ3 mm) are connected. The first protrusions 27b and the second protrusions 29b extend in a direction parallel to the contact surface 20a of the first binding plate 20 on the outer peripheral surface of the second section S2.

  In the height direction of the binding pin 22, the large circumferential surface 32 b is disposed from the contact surface 20 a of the first binding plate 20 to a height of 1.5 mm. The inclined surface 31b is disposed at a height of 1.5 to 2.1 mm. The second small circumferential surface 30b is disposed at a height of 2.1 to 2.4 mm. The second protrusion 29b is disposed at a height of 2.4 to 3.0 mm. The first small circumferential surface 28b is disposed at a height of 3.0 to 3.3 mm. The first protrusion 27b is disposed at a height of 3.3 to 3.9 mm.

  Therefore, the binding pin 22 has two steps different in position in the height direction, which are formed by the first protrusion 27b and the second protrusion 29b in the second section S2. Become. Then, the two steps formed by the first and second protrusions 27b and 29b are engaged with a receiving part 50b of the binding rod insertion hole 14 described later.

  On the outer peripheral surface of the third section S3, the first protruding portion 27c having a medium diameter from the head portion 23a of the binding pin 22 toward the root portion 23b (φ2.6 mm at the outermost periphery of the protruding portion). ), A first flat surface 28c separated from the central axis of the binding pin 22 by a predetermined distance (1 mm), and a second arc-shaped second protrusion 29c having a medium diameter (the diameter is the same as that of the sixth protrusion 27c φ2. 6 mm), a second plane 30c (a distance from the center axis of the binding pin 22 is the same as the first plane 28c), a predetermined distance (1 mm) away from the central axis of the binding pin 22, an inclined surface 31c, and a large diameter The large circumferential surface 32c (φ3 mm) is connected. The first protrusions 27c and the second protrusions 29c extend in a direction parallel to the contact surface 20a of the first binding plate 20 on the outer peripheral surface of the third section S3. The first plane 28c and the second plane 30c are planes orthogonal to the center line FF, respectively. The surface 28c and the surface 30c are flat so as to be in contact with a third receiving portion 50c of a later-described binding rod insertion hole 42 so as to be easily inserted into the binding rod insertion hole 42. For example, it may be a small circumferential surface similar to the first small circumferential surface 28a.

  In the height direction of the binding pin 22, the large circumferential surface 32 c is disposed to a height of 1.0 mm from the contact surface 20 a of the first binding plate 20. The inclined surface 31c is disposed at a height of 1.0 to 1.8 mm. The second plane 30c is disposed at a height of 1.8 to 2.1 mm. The second protrusion 29c is disposed at a height of 2.1 to 2.7 mm. The first plane 28c is disposed at a height of 2.7 to 3.0 mm. The first protrusion 27c is disposed at a height of 3.0 to 3.6 mm.

  Therefore, the binding pin 22 has two steps different in position in the height direction, which are formed by the first protrusion 27c and the second protrusion 29c in the third section S3. Become. Then, the two steps formed by the first and second protrusions 27c and 29c are engaged with a receiving part 50c of the binding rod insertion hole 14, which will be described later.

As a result, in the binding pin 22 as a whole, six steps that are formed by the six protrusions of the first protrusions 27a to 27c and the second protrusions 29a to 29c and have different positions in the height direction. Will have.
As shown in Table 1, the first protrusions 27 a to 27 c and the second protrusions 29 a to 29 c are arranged at a pitch of 0.3 mm in the height direction of the binding pin 22. Accordingly, the six steps formed by the first protrusions 27 a to 27 c and the second protrusions 29 a to 29 c are arranged at a pitch of 0.3 mm in the height direction of the binding pin 22. That is, when the binding tool of the third embodiment starts from a step (first protrusion 27b) on the side close to the head 23a of the binding pin 22, the binding tool 22 starts from the step formed by the first protrusion 27b. A step formed by the first protrusion 27a, a step formed by the first protrusion 27c, a step formed by the second protrusion 29b, a step formed by the second protrusion 29a, and a terminal end. In order to the level difference (second protrusion 29c) on the side closer to the root portion 23b, there are six stages of locking positions at a pitch of 0.3 mm in the height direction of the binding pin 22.

Each of the first protrusions 27 a to 27 c and the second protrusions 29 a to 29 c has a surface 35 (see FIG. 4) in the direction of insertion in the binding insertion hole 42 described later on the binding insertion hole 42. It has an inclined surface for easy insertion.
On the other hand, the surface 36 of each of the first protrusions 27a to 27c and the second protrusions 29a to 29c on the side opposite to the direction in which the first protrusions 27a to 27c are inserted into the binding insertion holes 42 is a binding insertion hole 42 described later. The first receiving portion 50a to the third receiving portion 50c are parallel to the contact surface 20a of the first binding plate 20 so that the first receiving portion 50a to the third receiving portion 50c are easily caught. That is, each position of the surface 36 becomes a locking position with any one of the first receiving portion 50a to the third receiving portion 50c. The shapes of the first protrusions 27a to 27c and the second protrusions 29a to 29c are arbitrary, and if they are caught by the first receiving part 50a to the third receiving part 50c of the binding rod insertion hole 42, the shapes thereof are It doesn't matter.
FIG. 10 is an explanatory diagram showing the positional relationship in the height direction of the first section S1 to the third section S3 of the binding pin 22. As shown in FIG. 10, the first ridges 27 a to 27 c and the second ridges 29 a to 29 c forming the step are such that the ridges adjacent in the height direction of the binding pin 22 are shifted in a step shape. It is formed and is intermittently formed in the circumferential direction of the binding pin 22 at different height positions in the height direction of the binding pin 22 for each of the first section S1 to the third section S3. The six ridges of the first ridges 27a to 27c and the second ridges 29a to 29c are connected to the root portion from the first ridge 27b at the start end of the binding pin 22 near the head 23a. The second protrusion 29c is located on the side close to 23b, and the second protrusion 29c is gradually turned counterclockwise in the circumferential direction of the binding pin 22 so as to have substantially two turns. In other words, after the first protrusions 27a to 27c of the first section S1 to the third section S3 have made approximately one turn while descending stepwise counterclockwise in the circumferential direction of the binding pin 22, the first section The second ridges 29a to 29c in the S1 to the third section S3 have a structure in which they make one round while descending stepwise counterclockwise in the circumferential direction of the binding pin 22.

  Furthermore, the lower surface of the first binding plate 20 (in the state where the object to be bound is bound by the binding tool of the third embodiment, it is a surface that becomes the outer side, hereinafter referred to as the outer surface) 20b A semicircular recess 38 is formed at a position corresponding to the position where the binding pin 22 is erected. When binding an object to be bound, a force can be effectively transmitted to the binding pin 22 by applying a force to this position.

(2) Binding rod insertion hole portion The binding rod insertion hole portion 14 has a substantially rectangular second binding plate 40 and one circular binding rod insertion hole 42 provided at a substantially central portion of the second binding plate 40. doing. The binding hole 42 is disposed at a position symmetrical to the position of the binding pin 22 with respect to the center line DD in the length direction of the binding device of the third embodiment. The binding pin insertion hole 42 is used for binding the binding object together with the binding pin 22 through the binding pin 22.

  When the binding device of the third embodiment binds the object to be bound, the second binding plate 40 has an upper surface (the object to be bound is bound in the state where the object to be bound is bound to the binding tool of the third embodiment). 40a is a surface that contacts the contact surface 20a of the first binding plate 20 of the binding pin portion 12. An abutting surface 40a of the second binding plate 40 is provided with an annular groove 44 having a U-shaped cross section at a predetermined distance outside the binding insertion hole 42. The contact surface 40a of the second binding plate 40 is a smooth surface because the object to be bound contacts.

  The first slit hole 45 that is wide from the position corresponding to the first boundary part 24 to the third boundary part 26 of the first section S1 to the third section S3 divided at equal intervals in the binding pin insertion hole 42. The second slit hole 46 and the third slit hole 47 extend radially in three directions at equal intervals of 120 degrees in a plan view from above, and the tips thereof reach the outer peripheral inner wall of the groove 44. The position of the first slit hole 45 is at the position of the center line FF in the width direction of the binding device of the third embodiment, and the first slit hole 45 to the third slit hole 47 are in relation to the center line FF. This is a line-symmetrical positional relationship. The first slit hole 45 to the third slit hole 47 are arranged so that their tips are farthest from the edge of the second binding plate 40. By separating the tips of the first slit hole 45 to the third slit hole 47 from the edge of the second binding plate 40, the second binding plate 40 is difficult to cut.

  When binding the object to be bound, the first boundary portion 24 of the binding pin 22 is inserted into the first slit hole 45. The second boundary portion 25 is inserted into the second slit hole 46. The third boundary portion 26 is inserted into the third slit hole 47. Therefore, the slit widths of the first slit hole 45 to the third slit hole 47 are set larger than the widths of the first boundary part 24 to the third boundary part 26.

  The groove 44 and the first slit hole 45 to the third slit hole 47 cooperate with each other with a force applied when the binding pin 22 is pushed into the binding insertion hole 42 when binding the object to be bound. It can be dispersed throughout the binding plate 40 to relieve mechanical stress.

The diameter of the circular binding pin insertion hole 42 at the contact surface 40a of the second binding plate 40 is larger than the diameter (φ3 mm) of the binding pin 22 (φ3.2 mm) so that the binding pin 22 can be easily inserted. The inner circumferential wall surface of the circular binding rod insertion hole 42 is divided into three parts at intervals in the circumferential direction of the binding rod insertion hole 42 around the center of the binding rod insertion hole 42. A first receiving portion 50a, a second receiving portion 50b, and a third receiving portion 50c to be locked are formed. The position of the third receiving portion 50c is at the position of the center line FF in the width direction of the binding tool 10, and the first receiving portion 50a to the third receiving portion 50c are line-symmetric with respect to the center line FF. It is a positional relationship.
Each of the first receiving portion 50a to the third receiving portion 50c is second bound so that the surface 51 (see FIG. 13) in the direction in which the binding pin 22 is inserted can be easily inserted. The diameter of the binding pin insertion hole 42 is inclined to decrease from the contact surface 40a of the plate 40 toward the back of the binding pin insertion hole 42, and the minimum diameter is the maximum diameter of the binding pin 22 ( smaller than φ3 mm) (φ2.2 mm).

  On the other hand, the surface 52 of each of the first receiving portion 50a to the third receiving portion 50c opposite to the direction in which the binding pin 22 is inserted is the first protrusions 27a to 27c of the binding pin 22. And it is a plane parallel to the contact surface 40a of the 2nd binding board 40 so that the 2nd protrusion part 29a-29c may be easily caught. That is, each position of the surface 52 becomes a locking position with any one of the protrusions 27a to 27c and 29a to 29c.

  Here, although not shown, the positions of the first receiving portion 50a, the second receiving portion 50b, and the third receiving portion 50c are different in the depth direction of the binding insertion hole 42. That is, the 1st receiving part 50a, the 2nd receiving part 50b, and the 3rd receiving part 50c are arrange | positioned from the contact surface 40a of the 2nd binding board 40 toward the back of the binding pin insertion hole 42. FIG. Therefore, in the depth direction of the binding rod insertion hole 42, the position of the surface 52 of the first receiving portion 50a from the contact surface 40a of the second binding plate 40 toward the back of the binding rod insertion hole 42, the second receiving portion. There are the position of the surface 52 of 50b and the position of the surface 52 of the 3rd receiving part 50c.

  In the depth direction of the binding insertion hole 42, the distance (pitch) between the position of the surface 52 of the adjacent first receiving portion 50a and the position of the surface 52 of the second receiving portion 50b is the adjacent second receiving portion. The distance (pitch) between the position of the surface 52 of the 50b and the position of the surface 52 of the third receiving portion 50c is set to be equal. Furthermore, the distance (pitch) between the position of the surface 52 of the adjacent first receiving portion 50a and the position of the surface 52 of the second receiving portion 50b, the position of the surface 52 of the adjacent second receiving portion 50b, and the third receiving portion. The distance (pitch) from the position of the surface 52 of 50c is smaller than the distance (pitch) between the first protrusion 127 and the second protrusion 129 adjacent in the height direction of the binding pin 122, for example. Is set to

Therefore, when the binding pin 22 is inserted into the binding pin insertion hole 42 when the binding tool of the third embodiment binds the object to be bound, first, the surface 52 of the first receiving portion 50a is moved to the binding pin. 22 is hooked on the first ridge 27a in the first section S1, and then the surface 52 of the second receiving portion 50b is hooked on the first ridge 27b in the second section S2 of the binding pin 22. Similarly, when the binding pin 22 is further inserted into the binding pin insertion hole 42, any one of the surface 52 of the first receiving portion 50a to the surface 52 of the third receiving portion 50c is successively connected to the binding pin. The first protrusions 27a to 27c and the second protrusions 29a to 29c of 22 are hooked. That is, according to the depth at which the binding pin 22 is inserted into the binding pin insertion hole 42, one of the first protrusions 27a to 27c and the second protrusions 29a to 29c of the binding pin 22 is inserted into the binding. The insertion depth of the binding pin 22 into the binding pin insertion hole 42 is adjusted by sequentially engaging with any one of the receiving portions 50a to 50c of the hole 42.
As a result, the binding tool of the third embodiment has a structure having a multi-stage locking position, and can be finely adjusted step by step according to the thickness of the object P to be bound.

However, the 1st receiving part 50a-the 3rd receiving part 50c have elasticity, and when it latches to the binding pin 22, the height position of the 1st receiving part 50a-the 3rd receiving part 50c changes. . That is, the first receiving portion 50 a to the third receiving portion 50 c are locked to the binding pin 22 by elastic force, and the binding pin 22 is closely fitted in the binding pin insertion hole 42.
The binding rod insertion hole 42 on the lower surface 40b of the second binding plate 40 (which is the outer surface when the object to be bound is bound by the binding tool of the third embodiment, hereinafter referred to as the outer surface) 40b. The diameter is the same as the maximum diameter (φ3 mm) of the binding pin 22. In addition, the shape of the 1st receiving part 50a-the 3rd receiving part 50c is arbitrary, The shape will be used if it hooks on the 1st protrusion part 27a-27c and the 2nd protrusion part 29a-29c of the binding pin 22 Does not matter.

(3) Connection part The connection part 16 is arrange | positioned between the binding pin part 12 and the binding pin insertion hole part 14. As shown in FIG. An upper surface 16a of the rectangular connecting portion 16 (a surface to be bound comes into contact in a state where the object to be bound is bound by the binding tool of the third embodiment, hereinafter referred to as a contact surface) 16a Since the end of the object abuts, the surface is smooth. The contact surface 16a is located at a position retracted from the contact surface 20a of the first binding plate 20 of the binding pin portion 12 and the contact surface 40a of the second binding plate 40 of the binding pin insertion hole 14. Therefore, when the binding device of the third embodiment is bent inward in the length direction of the binding tool by the hinge portions 18 and 19, the connecting portion 16 collides with the binding pin portion 12 and the binding pin insertion hole portion 14. Can be prevented.

  On the other hand, a lower surface 16b of the connecting portion 16 (which is an outer surface when the object to be bound is bound by the binding tool of the third embodiment, hereinafter referred to as an outer surface) 16b is curved downward. Inflated. The contact surface 20a of the first binding plate 20 and the contact surface 40a of the second binding plate 40 are substantially flush with each other.

Yes. The second hinge portion 19 is for connecting the binding rod insertion hole portion 14 and the connecting portion 16, and is disposed between the binding rod insertion hole portion 14 and the connecting portion 16 so as to be freely bent. The hinge portions 18 and 19 extend in the width direction of the binding tool of the third embodiment, and the binding tool can be bent in the length direction thereof. In addition, the shape of the hinge parts 18 and 19 is arbitrary, for example, the hinge width may be narrow and the hinge thickness may be thin.

R-shaped concave portions 18a, 18b, 19a, 19b are formed at both ends of the hinge portions 18, 19, so that the hinge portions 18, 19 are difficult to break.
In addition, the hinge parts 18 and 19 and the connection part 16 are not necessarily required, and one of them may be configured to have the other function.
