The two binding rings 14 are twisted so that the binding ring locking portion 50 can be disengaged.
However, the B-side through-hole 26a and the B-side through-hole 28a are locked with the weight of the binding object S to which the binding ring locking portion 50 of the first binding member 12a in the locked state is bound. The distance L2 is shorter than the distance L1 when the first binding ring 12 and the second binding ring 14 are closed so that the movement in the direction O1 from which the part 50 is removed can be restricted. It is comprised so that it may become.

When the binding rings 12 and 14 are closed and the binding rings are twisted to open the binding rings 12 and 14, one binding member (the first binding member 12 a and the third binding member 14 a) is bound. The other binding member (the second binding member 12b and the fourth binding member 14b) disengages the binding ring locking portion 50 while moving to the near side, which is the side from which the ring locking portion 50 is disengaged. One through-hole (B-side through-hole 26a, B-side through-hole) through which one binding member (the first binding member 12a, the third binding member 14a) is inserted in order to move to the other side, which is the side 28a) is formed to allow movement of one binding member (first binding member 12a, third binding member 14a), and the other binding member (second binding member 12b, fourth binding member). 14b) and the other through hole (A side through hole 26b, A side through hole) Hole 28b) is formed so as to permit movement of the other binding member (the second binding member 12b, a fourth binding member 14b).
The movement restricting portion is formed to allow movement of one binding member (the first binding member 12a and the third binding member 14a), and the other binding member (the second binding member 12b and the fourth binding member). It is formed to allow movement of member 14b).
Then, an overload is applied only to the binding rings 12 and 14 in the direction of releasing the engagement of the binding ring locking portion 50 of one binding member (the first binding member 12a and the third binding member 14a) of the binding object S. When applied, one of the binding members (the first binding member 12a and the third binding member 14a) is inserted into one of the through holes (B side through hole 26a, B side through hole 28a). One binding member (first binding member 12a, third binding member 14a) moved to the side of disengaging the binding ring locking portion 50 of the members (first binding member 12a, third binding member 14a). ) And the other through-hole (A-side through-hole 26b, A-side through-hole) inserted through the other binding member (second binding member 12b, fourth binding member 14b). The hole 28b) is formed on the other binding member (second binding member 12b, fourth binding member). The material 14b) is formed to allow further movement toward the one of the stopped binding members (the first binding member 12a and the third binding member 14a), and the movement restricting portion includes: One binding member (the first binding member 12a, the third binding member 14a) is moved to the side of releasing the engagement of the binding ring locking portion 50 (the first binding member 12a, the third binding member 14a). The other binding members (the second binding member 12b and the fourth binding member 14b) are further allowed to move toward the binding member 14a).

  In the binding ring locking portion 50, the locking convex portions (the convex portion 52a and the convex portion 56a) of one binding member (the first binding member 12a and the third binding member 14a) protrude toward the other side. And the latching convex part (convex part 54a, convex part 58a) of the other binding member (the 2nd binding member 12b, the 4th binding member 14b) protrudes toward this side, and the binding ring latching part 50 When the binding ring which is disengaged and is closed is twisted and opened, the locking convex portions (the convex portions 52a and the convex portions 56a) of one of the binding members (the first binding member 12a and the third binding member 14a). ) Is moved in the direction opposite to the direction in which the first binding member protrudes (the first binding member 12a and the third binding member 14a) and the other binding member (second binding member 12b and fourth binding member). Of the binding member 14b) of the binding member 14b) is protruding. The other binding member (the second binding member 12b, the fourth binding member 14b) is moved toward the opposite side to the one binding member (the first binding member 12a, the third binding member 14a). The engaging protrusions (protrusions 52a, 56a) are disengaged from the engaging recesses (recesses 54b, 58b) of the other binding member (second binding member 12b, fourth binding member 14b) and The locking convex portions (the convex portions 54a and the convex portions 58a) of the other binding member (the second binding member 12b and the fourth binding member 14b) are used as one binding member (the first binding member 12a and the third binding member). The member 14a) can be disengaged from the locking recess (the recess 52b and the recess 56b).

When the first binding ring 12 as the main binding ring is sandwiched between two fingers and the binding ring starts to close, the convex portions 56a of the third binding member 14a of the second binding ring 14 and the second binding ring 14 Before the concave portion 58b of the fourth binding member 14b comes into contact (see FIG. 19), the convex portion 52a of the first binding member 12a of the first binding ring 12 and the second binding of the first binding ring 12 are performed. When the convex portion 54a of the member 12b comes into contact with the first binding ring 12 and is further operated to close, the concave portion 52b of the first binding member 12a of the first binding ring 12 becomes the second binding member 12b. While sliding on the convex part 54a, the convex part 52a of the 1st binding member 12a of the 1st binding ring 12 passes the regular latching position fitted to the recessed part 54b of the 2nd binding member 12b. The convex portion 52a of the first binding member 12a is inclined to the concave portion 54b of the second binding member 12b. Ride up on the opposite surface to slide (see Fig. 20).
In this way, when the first binding ring 12 is operated in the closing direction, the convex portions 56a of the third binding member 14a of the second binding ring 14 and the fourth binding member 14b of the second binding ring 14 are moved. When the convex portion 58a abuts and further operates to close the first binding ring 12, the convex portion 56a of the third binding member 14a of the second binding ring 14 becomes convex of the fourth binding member 14b. Sliding on the inclined facing surface 58c of the portion 58a (see FIG. 19), and the convex portion 52a of the first binding member 12a of the first binding ring 12 is further inclined to the inclined facing surface of the concave portion 54b of the second binding member 12b. Is raised, the convex portion 56a of the third binding member 14a of the second binding ring 14 (the convex portion 58a of the fourth binding member 14b) becomes the concave portion 58b of the fourth binding member 14b (third binding member). It fits into the recess 56b) of 14a (see FIG. 20).
After that, when the finger is released from the first binding ring 12 and the closing force is released, the opening and closing member 40 causes the first binding ring 12 to reverse slightly in the opening direction, so that the first binding ring 12 Similarly to the binding ring 14 of the first binding member 12a, the convex portion 52a of the first binding member 12a (the convex portion 54a of the second binding member 12b) is the concave portion 54b of the second binding member 12b (the concave portion 52b of the first binding member 12a). ) (See FIG. 21).

When closing the binding ring, the first working piece 30 and the second working piece 32 gradually change from the mountain-folded state (see FIG. 15) to the planar state (see FIG. 10) and from the state in which they are aligned in the same row. Once moved in the direction in which the binding ring locking portion 50 comes off (the first working piece 30 is in the O1 direction and the second working piece 32 is in the O2 direction), they are lined up one after another (see FIG. 20). Go back and line up in the same row.
Thereby, the restriction convex part 30g of the first working piece 30 constituting the movement restriction part moves in the restriction concave part 32f of the second working piece 32, and the binding ring locking part 50 in the restriction concave part 32f is released. The regulating convex portion 32g of the second working piece 32 that contacts the edge opposite to the side and that constitutes the movement regulating portion moves in the regulating concave portion 30f of the first working piece 30, and in the regulating concave portion 30f. It abuts on the edge opposite to the direction in which the binding ring locking portion 50 comes off (see FIG. 11). Therefore, when the binding ring is closed, the convex portion 52a of the first binding member 12a of the first binding ring 12 passes through the normal stop position where the convex portion 52a is fitted into the concave portion 54b of the second binding member 12b, and When the convex portion 52a of the first binding member 12a slides on the inclined opposing surface of the concave portion 54b of the second binding member 12b and overruns, the movement distance of the first binding ring 12 is regulated appropriately. The overrun is stopped at a certain position, and when the finger is removed from the binding ring locking portion 50 of the first binding ring 12, a force to return the opening / closing member 40 to the original state acts, and the first operating piece 30. And the second operating piece 32 once moved in the direction in which the binding ring locking portion 50 is disengaged (the first operating piece 30 is in the O1 direction and the second operating piece 32 is in the O2 direction). From the reverse, they are arranged in the same row, and the binding ring locking portion 50 is fitted ( See 9,10,19,20 and 21).

As described above, when the first binding ring 12 that is the main binding ring is started to close, the second binding ring 14 that is the secondary binding ring that cannot be directly closed by the finger starts to move in the closing direction, and further, the first binding ring 12 is further closed. If the second binding ring 14 is engaged and the second binding ring 14 is completely locked before the first binding ring 12, the second binding ring 14 is completely locked. After the second binding ring 14 that is the secondary binding ring that is not closed by the finger is securely locked, the first binding ring 12 that is the main binding ring is securely locked.
Therefore, if the first binding ring 12 is picked so as to overrun when the first binding ring 12 is picked with a finger and moved in the first closing direction, the second binding ring 14 is surely properly connected. And can be closed only by operating the first binding ring 12.
Thus, since the 2nd binding ring 14 can be closed by operating the 1st binding ring 12 with a finger, the convenience as a one-touch binding tool is high.

When the binding ring locking portion 50 of the first binding ring 12 is removed by twisting the top of the first binding ring 12 with a finger, the first operating piece 30 and the second operating piece 32 are twisted. As shown in the direction of the arrows in FIGS. 6B and 6C, the force that the openable opening / closing member 40 returns to the original state, that is, one first erection part 44 and the other second erection part 46 are connected. The first binding ring 12 is opened by a force acting so as to rotate in the circumferential direction of the portion 42 to return to the original state.
Further, the first binding ring 12 and the second binding ring 14 have the binding ring locking portion 50 removed (see FIG. 11), and the first operating piece 30 and the second operating piece 32 are the binding ring. It moves in the direction in which the locking portion 50 is released (the first operating piece 30 is in the O1 direction and the second operating piece 32 is in the O2 direction) (see FIG. 14A). Thereby, the restriction convex part 30g of the first working piece 30 constituting the movement restriction part moves in the restriction concave part 32f of the second working piece 32, and the binding ring locking part 50 in the restriction concave part 32f is released. The restricting convex portion 32g of the second operating piece 32 that hits the edge opposite to the side and that constitutes the movement restricting portion moves in the restricting concave portion 30f of the first actuating piece 30, and binds in the restricting concave portion 30f. It abuts against the edge opposite to the direction of the ring locking portion 2 (see FIG. 14B).
When the force of releasing or twisting the hand from the first binding ring 12 is weakened, the first binding ring 12 and the second binding ring 14 have the first erection part 44 and the second erection part 46 of the opening / closing member 40, 6B and 6C, a force that rotates in the circumferential direction of the connecting portion 42 to return to the original state is applied to the first working piece 30 and the second working piece 32, as indicated by the arrows in FIGS. As a result, the first operating piece 30 and the second operating piece 32 change from the flat state to the mountain folded state, and further open (the first binding member 12a and the third binding member 14a are in the O3 direction, The binding member 12b and the fourth binding member 14b are in the O4 direction), and the first erection part 44 and the second erection part 46 of the opening / closing member 40 are returned to the original state, thereby the first operating piece 30 and The second operating piece 32 moves in the opposite direction (see FIGS. 14A and 14B).
That is, the actuating member 18 and the opening / closing member 40 act in a direction to open the convex portion 56a of the third binding member 14a and the convex portion 58a of the fourth binding member 14b constituting the second binding ring 14, and The first binding ring 12 acts in a direction to separate the convex portion 52a of the first binding member 12a and the convex portion 54a of the second binding member 12b, and the third binding ring 14 constitutes the third binding ring 14. It acts so that the convex part 56a of the binding member 14a and the convex part 58a of the 4th binding member 14b may be pulled apart.

  As described above, in this embodiment, the first binding member 12a and the second binding member 12a of the first binding ring 12 are twisted by twisting the top of the first binding ring 12 or the second binding ring 14 with a finger. The binding ring locking part 50 of the binding member 12b and the binding ring locking part 50 of the third binding member 14a and the fourth binding member 14b of the second binding ring 14 can be removed.

  The first binding member 12 a and the second binding member 12 b of the first binding ring 12, and the third binding member 14 a and the fourth binding member 14 b of the second binding ring 14. When the engagement of the binding ring locking part 50 is released and the twisting force is removed or weakened, the first erection part 44 and the second erection part 46 of the opening / closing member 40 are in the same direction in the circumferential direction of the connecting part 42 The actuating member 18 acts on the butt edge 30a of the first actuating piece 30 and the second edge by a force acting to move to the original state (that is, a force to return to the original state where no force is applied to the opening / closing member 40). With the butt edge 32a of the operating piece 32 as a pivot, the first oscillating member swings by the force of returning to the connecting portion 42 and the force of returning to the original of the first erection portion 44 and the second erection portion 46. The working piece 30 and the second working piece 32 move in the opposite directions. The edge 32a abutting the abutting edge 30a is increased in the direction projecting the binding ring, the mountain fold state.

  When the first binding ring 12 and the second binding ring 14 are bound to the object S to be bound and the cover CO is set up in the length direction of the binding tool 10, One of the first binding member 12a and the third binding member 14a is the B-side through hole 26a and the B-side through hole 28a, and the binding ring locking portion 50 of the first binding ring 12 and the second binding ring 14 is used. The second binding member 12b and the fourth binding member 14b are not restricted from moving by the A side through hole 26b and the A side through hole 28b. The binding ring locking portion 50 of the second binding member 12b bites into the binding ring locking portion 50 of the first binding member 12a, and the binding ring locking portion 50 of the fourth binding member 14b is the third binding member 14a. The first binding ring by biting into the binding ring locking portion 50 of the first binding ring 2 and the second binding ring 14 is prevented from opening by disengagement.

Next, a method for loading the actuating member 18 into the holding space of the holding member 16 will be described mainly with reference to FIGS.

That is, the first holding wall 24a is spaced from the lower edge of the first holding wall 24a for forming the first holding portion 60 and the first holding portion 62 in the vicinity of the through hole 26 on the far side. A thin notch 68a and a notch 70a are formed, and a region between the notch 68a and the notch 70a and the lower edge of the first holding wall 24a is struck outward from the first holding wall 24a. The 1 holding part 60 and the 1st holding part 62 are formed (refer FIG.22 (B)).
The second holding wall 24b is spaced from the lower edge of the second holding wall 24b for forming the second holding portion 64 and the second holding portion 66 in the vicinity of the through hole 28 on the near side. A thin notch 72a and a notch 74a are formed, and a region between the notch 72a and the notch 74a and the lower edge of the second holding wall 24b is struck outward from the second holding wall 24b. 2 holding | maintenance part 64 and the 2nd holding | maintenance part 66 are formed (refer FIG. 22 (A)).
When loading the operating member 18 into the holding space of the holding member 16, first, the first operating piece 30 is loaded into the holding member 16, and then the second working piece 32 is loaded into the holding member 16. (See FIG. 23A).
At this time, the protruding portion 30c1 of the first working piece 30 is located inside the first holding portion 60, and the protruding portion 30c2 of the first working piece 30 is located inside the first holding portion 62. The protrusion 32c1 of 32 is located inside the second holding part 64, and the protrusion 32c2 of the second operating piece 32 is located inside the second holding part 66.
Next, the first holding unit 60, the first holding unit 62, the second holding unit 64, and the second holding unit 66 are driven toward the inside of the first holding wall 24a and the second holding wall 24b, and a planar circle is formed. An arc-shaped first holding unit 60, first holding unit 62, second holding unit 64, and second holding unit 66 are formed (see FIG. 23B).
Thus, the first holding portion 60 protrudes from the lower surface of the protruding portion 30c1, the first holding portion 62 protrudes from the lower surface of the protruding portion 30c2, the second holding portion 64 protrudes from the lower surface of the protruding portion 32c1, and the second holding portion 66 protrudes. It is formed so as to hold the lower surface of the portion 32c2. The protrusion 30c1 is outside the through hole 26 on the far side, the protrusion 30c2 is outside the through hole 28 on the near side, the protrusion 32c1 is outside the through hole 26 on the far side, and the protrusion 32c2 is on the near side. It protrudes outside from the through hole 28.

Next, a method for loading the opening / closing member 40 into the operating member 18 will be described with reference to FIGS.
The opening / closing member 40 includes a connection portion (second connection portion) that connects the connection portion 42 and the second installation portion 46 at a connection portion (first connection portion 48a) that connects the connection portion 42 and the first installation portion 44. 48b), a steel wire having elasticity such as a straight piano wire is bent at substantially the same angle in the opposite direction and formed in a substantially Z shape in plan view, and The second erection part 46 is bent downward and is formed in a tapered shape in side view.
The connecting part 42 and the second erection part 46 are bent so as to form an angle of approximately 110 degrees in plan view, and the connecting part 42 and the first erection part 44 form an angle of approximately 110 degrees in plan view. The connecting part 42 and the second erection part 46 are bent so as to form an angle of about 110 degrees in a side view, and the connection part 42 and the second erection part 46 are substantially in a side view. It is bent at an angle of 110 degrees.
The first erection part 44 is in a state where the first operating piece 30 and the second operating piece 32 are abutted in a plane (that is, the first binding ring 12 and the second binding ring 14 are closed). In this case, the first binding member 12a and the third binding member 14a are closed, that is, the butting edge 30a of the first operating piece 30 is raised toward the binding object mounting portion 22 side of the holding member 16 for mountain folding. In the state twisted in the direction to be in the state, it is bridged between the first opening / closing member fixing portion 38a of the second operating piece 32 and the third opening / closing member fixing portion 38c of the first operating piece 30, The vicinity of the tip of the one erection part 44 is locked to the third opening / closing member fixing part 38 c of the first operating piece 30.
The second erection part 46 is in a state in which the first operating piece 30 and the second operating piece 32 are abutted in a plane (that is, a state in which the first binding ring 12 and the second binding ring 14 are closed). The first binding portion 44 is a direction in which the first working piece 30 is in the mountain folded state, that is, a direction in which the first binding member 12a and the third binding member 14a are closed. The second opening / closing member fixing portion of the first operating piece 30 in the state of being fixed to the third opening / closing member fixing portion 38c of the first operating piece 30 while being twisted toward the upper side where the two binding rings 14 protrude. 38b and the fourth opening / closing member fixing portion 38d of the second operating piece 32, and the vicinity of the tip of the second erection portion 46 is locked to the fourth opening / closing member fixing portion 38d of the second operating piece 32. .
That is, in the state where the first binding ring 12 and the second binding ring 14 are closed, the first operating piece 30 and the second operating piece 32 are moved in the direction from the open state to the closed state.

  The binding tool 610 includes a pair of substantially annular metal first binding ring 612, second binding ring 613, and third binding ring 614, and the first binding ring 612 to the third binding ring. A holding member 616 having a length capable of providing 614 at intervals, and a first binding ring 612 to a third binding ring 614 on the surface of the holding member 616 and the respective bases thereof are fixed at intervals. The first binding ring 612, the second binding ring 613, and the third binding ring 614 include an operation member 618 movably fixed inside the holding member 616 so as to be fixed to the holding member 616.

The binding ring is composed of three binding rings of a first binding ring 612, a second binding ring 613, and a third binding ring 614 for the three-hole type. The first binding ring 612 includes a first binding member 612a and a second binding member 612b, and the second binding ring 613 includes a third binding member 613a and a fourth binding member 613b. The binding ring 614 includes a fifth binding member 614a and a sixth binding member 614b.
Then, the first binding member 612a and the second binding member 612b are configured so that the binding object S such as a sheet can be bound by being inserted into a binding hole previously formed in the binding object S such as a sheet. , The third binding member 613a and the fourth binding member 613b, and the fifth binding member 614a and the sixth binding member 614b, that is, the first binding ring 612 and the second binding member 614b. A binding ring locking portion 650 is formed at the top of the binding ring 613 and the third binding ring 614.

The first binding ring 612, the second binding ring 613, and the third binding ring 614 constituting the binding ring are made of a metal wire having a circular cross section in a direction in which the binding ring locking portion 650 is removed (O1 in FIG. 36). And the O2 direction), and the center portion is pressed to bend the binding ring in the closing direction. The first binding ring 612, the second binding ring 613, and the third binding ring 614 are arranged in the direction in which the center opens the binding ring (the first binding member 612a, the third binding member 613a, and the fifth binding ring).
