From the state of being lined up in a line, it is reversed and arranged in the same row, and the binding lock portion 50 is fitted (see FIGS. 9 and 10).

As described above, when the first binding rod 12 that is the main binding rod is started to close, the second binding rod 14 that is a secondary binding rod that cannot be closed directly by the finger starts to move in the closing direction, and further, the first binding rod 12 is further closed. Is closed and moved until it passes the normal locking position, the engagement of the second binding rod 14 advances, and the second binding rod 14 is completely locked before the first binding rod 12, so that After the second binding rod 14 that is a secondary binding rod that cannot be closed by a finger is securely locked, the first binding rod 12 that is the main binding rod is reliably locked.
Therefore, if the first binding rod 12 is picked so as to overrun when the first binding rod 12 is picked with a finger and moved in the first closing direction, the second binding rod 14 can be surely secured. And can be closed only by operating the first binding rod 12.
Thus, since the 2nd binding 14 can be closed by operating the 1st binding 12 with a finger | toe, the convenience as a one-touch binding tool is high.

When the binding portion 50 of the first binding rod 12 is removed by twisting the top of the first binding rod 12 with a finger, the first operating piece 30 and the second operating piece 32 include As shown in FIG. 6 (A), the force at which the opening / closing member 40 returns to the original state, that is, one fixed tip 42a and the other fixed tip 42b are parallel to the circumferential direction of the winding 44. When the force works so as to return to the original state, the first binding 12 is opened.
Then, the first binding rod 12 and the second binding rod 14 are removed from the binding locking portion 50 (see FIG. 11), and the first operating piece 30 and the second operating piece 32 are valley-folded. The state gradually changes to a flat state (neutral state) and further changes from a flat state to a mountain fold state, and the direction in which the binding latch 50 is disengaged (the first operating piece 30 is the O1 direction, and the second operating piece 32 is the O2 Direction). Thereby, the restriction protrusion 30g of the first operating piece 30 constituting the movement restricting portion moves in the restricting recess 32f of the second actuating piece 32, and the binding lock portion 50 is released from the restricting recess 32f. The regulating protrusion 32g of the second working piece 32 that makes contact with the edge opposite to the side and that constitutes the movement regulating portion moves in the regulating recess 30f of the first working piece 30, and the binding in the regulating recess 30f. It strikes against the edge opposite to the direction in which the hook locking portion 50 comes off.
When the hand is released from the first binding rod 12, the first binding rod 12 and the second binding rod 14 have one fixed tip 42 a and the other fixed tip 42 b of the opening / closing member 40, as shown in FIG. As shown in A), by applying a force to the first working piece 30 and the second working piece 32 so as to return to the original state that was parallel to the circumferential direction of the winding portion 44, further, Opening (the first half split 12a and the third half split 14a are in the O3 direction, the second half split 12b and the fourth half split 14b are in the O4 direction), and the fixed tip of the opening / closing member 40 The first working piece 30 and the second working piece 32 move in opposite directions by applying a force so that 42a and the other fixed tip 42b are parallel to each other in plan view (see FIG. 14).
In other words, the actuating member 18 and the opening / closing member 40 act in the direction of opening the convex portion 56a of the third half-split bar 14a and the convex portion 58a of the fourth half-split bar 14b constituting the second binding rod 14. The first binding rod 12 acts in a direction to separate the convex portion 52a of the first half-cotton rod 12a and the convex portion 54a of the second half-cotton rod 12b, and constitutes the second binding rod 14. The convex part 56a of the 3rd half split 14a and the convex part 58a of the 4th half split 14b to act are pulled apart.

  Thus, in this embodiment, by twisting the top of the first binding rod 12 or the second binding rod 14 with a finger, the first half-split 12a and the second second binding rod 12a of the first binding rod 12 The binding hook locking portion 50 of the half split hook 12b and the binding hook locking portion 50 of the third half split hook 14a and the fourth half split hook 14b of the second binding hook 14 can be removed.

  Further, the first half split bar 12a and the second half split bar 12b of the first binding bar 12 and the third half split bar 14a and the fourth half split bar 14b of the second binding bar 14 are provided. When the binding of the binding member 50 of the half split bar 14b is released, the actuating member 18 is configured such that one fixed tip 42a and the other fixed tip 42b of the opening / closing member 40 are the circumference of the winding portion 44. When the force which approaches in the direction works, the butt edge 30a of the first working piece 30 and the butt edge 32a of the second working piece 32 are in a mountain fold state.

The surface 256c and the inclined facing surface 258c are in contact with each other in a circumscribed relationship sharing one point.

When the first binding pin 212 that is the main binding rod is sandwiched between two fingers and the binding rod starts to close, the convex portion 256a of the third half-split 214a of the second binding rod 214 and the second binding rod 214 Before the concave portion 258b of the fourth half-split bar 214b comes into contact (see FIG. 51), the convex portion 252a of the first half-split bar 212a of the first binding pin 212 and the first splicing pin 212 When the convex portion 254a of the second half-cotton 212b is brought into contact with and further operated to close the first binding rod 212, the concave portion 252b of the first half-cotton 212a of the first binding rod 212 becomes the second. And the convex portion 252a of the first half collar 212a of the first binding rod 212 is fitted into the concave portion 254b of the second half collar 212b. After passing through the normal locking position, the convex portion 252a of the first half-cotton 212a Ride up the inclined opposing face on parts 254b to slide (see Fig. 52).
In this way, when the first binding rod 212 is operated in the closing direction, the convex portion 256a of the third half-split 214a of the second binding rod 214 and the fourth half-split of the second binding rod 214 are provided. When the convex portion 258a of 214b is brought into contact with and further operated to close the first binding rod 212, the convex portion 256a of the third half split collar 214a of the second binding rod 214 becomes the fourth half split. It slides on the inclined opposing surface 258c of the convex part 258a of the collar 214b (see FIG. 51), and the convex part 252a of the first half collar 212a of the first binding collar 212 further has the second half collar 212b. When the inclined facing surface of the concave portion 254b is lifted, the convex portion 256a of the third half-split 214a of the second binding rod 214 (the convex portion 258a of the fourth half-split 214b) becomes the fourth half-split 214b. Is fitted into the recess 258b (the recess 256b of the third half-cut flange 214a) (see FIG. See 2).
Thereafter, when the finger is released from the first binding rod 212 and the closing force is released, the opening and closing member 240 causes the first binding rod 212 to reverse slightly in the opening direction, and the first binding rod 212 In the same manner as the binding rod 214, the convex portion 252a (the convex portion 254a of the second half-split plate 212b) of the first half-split plate 212a is the concave portion 254b (the first half-split plate 212b) of the second half-split plate 212b. It fits into the recess 252b) of 212a (see FIG. 53).

When closing the binding, the first working piece 230 and the second working piece 232 gradually change from the mountain-folded state (see FIG. 47) to the flat state (neutral state), and further from the flat state (neutral state) to the valley fold. The state changes (see FIG. 42), and from the state of being arranged in the same row, once the binding latch 250 is moved away (the first operating piece 230 is in the O1 direction and the second operating piece 232 is in the O2 direction). As a result, they are arranged in a line (see FIG. 52), and then return to the same line.
Thereby, the restriction protrusion 230g of the first operating piece 230 constituting the movement restricting portion moves in the restricting recess 232f of the second actuating piece 232, and the binding staple locking portion 250 in the restricting recess 232f is released. The control protrusion 232g of the second working piece 232 that contacts the edge opposite to the side and that constitutes the movement restricting portion moves in the restricting recess 230f of the first actuating piece 230, and in the restricting recess 230f. It abuts on the edge opposite to the direction in which the binding lock 250 is removed (see FIG. 52). Therefore, when closing the binding rod, the convex portion 252a of the first half-split 212a of the first binding rod 212 passes through the normal stop position where the convex portion 254b of the second half-split 212b is fitted. When the convex portion 252a of the first half-cut collar 212a slides on the inclined opposing surface of the concave portion 254b of the second half-cut collar 212b and overruns, the movement distance of the first staple 212 is increased. The overrun is stopped at an appropriate position by restricting, and if the finger is removed from the binding hook locking portion 250 of the first binding rod 212, a force is applied to return the opening / closing member 240 to the original state. The operating piece 230 and the second operating piece 232 once moved in the direction in which the binding lock portion 250 is released (the first operating piece 230 is in the O1 direction and the second operating piece 232 is in the O2 direction). From the state of being lined up in a row, it is reversed and lined up in the same row, and the binding lock portion 2 0 is fitted (see FIGS. 41 and 42).

In this way, when the first binding 212 as the main binding starts to close, the second binding 214 as the secondary binding that cannot be closed directly with the finger starts to move in the closing direction, and further the first binding 212 is started. And the second binding rod 214 is engaged, and the second binding rod 214 is completely locked before the first binding rod 212. After the second binding rod 214, which is a secondary binding rod that cannot be closed by a finger, is securely locked, the first binding rod 212, which is the main binding rod, is securely locked.
Therefore, if the first binding pin 212 is picked so as to overrun when the first binding pin 212 is moved with the finger in the first closing direction, the second binding pin 214 can be surely secured. And can be closed only by operating the first binding 212.
Thus, since the 2nd binding pin 214 can be closed by operating the 1st binding pin 212 with a finger | toe, the convenience as a one-touch binding tool is high.

In addition, when the binding hook locking portion 250 of the first binding rod 212 is removed by twisting the top of the first binding rod 212 with a finger, the first operating piece 230 and the second operating piece 232 include The force with which the opening / closing member 240 returns to the original state, that is, one fixed tip 242a and the other fixed tip 242b are parallel to the circumferential direction of the winding 244, as shown in FIG. When the force works to return to the original state, the first binding pin 212 is opened.
Then, the first binding pin 212 and the second binding pin 214 are removed from the binding pinching portion 250 (see FIG. 43), and the first working piece 230 and the second working piece 232 are valley-folded. The state gradually changes to a flat state (neutral state) and further changes from the flat state to the mountain fold state, and the direction in which the binding hook locking portion 250 is disengaged (the first operating piece 230 is the O1 direction, and the second operating piece 232 is the O2 direction. Direction). Thereby, the restriction protrusion 230g of the first operating piece 230 constituting the movement restricting portion moves in the restricting recess 232f of the second actuating piece 232, and the binding staple locking portion 250 in the restricting recess 232f is released. The regulating protrusion 232g of the second operating piece 232 that makes contact with the edge opposite to the end and moves in the restricting recess 230f of the first actuating piece 230 moves in the restricting recess 230f. It strikes against the edge opposite to the direction in which the hook locking portion 250 comes off.
When the hand is released from the first binding rod 212, the first binding rod 212 and the second binding rod 214 have one fixed tip 242a and the other fixed tip 242b of the opening / closing member 240 as shown in FIG. As shown in A), by applying a force to the first working piece 230 and the second working piece 232 so as to return to the original state that was parallel to the circumferential direction of the winding portion 244, Opening (the first half split 212a and the third half split 214a are in the O3 direction, and the second half split 212b and the fourth half split 214b are in the O4 direction), and the fixing tip of the opening / closing member 240 The first working piece 230 and the second working piece 232 move in opposite directions by applying a force so that 242a and the other fixed tip 242b are parallel to each other in plan view (see FIG. 46).
That is, the actuating member 218 and the opening / closing member 240 act in a direction to open the convex portion 256a of the third half-split 214a and the convex portion 258a of the fourth half-split 214b constituting the second binding rod 214. Then, the first binding rod 212 acts in a direction to separate the convex portion 252a of the first half-cotton 212a and the convex portion 254a of the second half-cotton 212b, and constitutes the second binding rod 214. The convex portion 256a of the third half-cut rod 214a and the convex portion 258a of the fourth half-cut rod 214b act to separate.

  Thus, in this embodiment, by twisting the top of the first binding rod 212 or the second binding rod 214 with a finger, the first half-split 212a and the second half of the first binding rod 212 The binding hook locking portion 250 of the half split collar 212b and the binding hook locking portion 250 of the third half split collar 214a and the fourth half split collar 214b can be removed.

  In addition, the first half split bar 212a and the second half split bar 212b of the first binding bar 212 and the third half split bar 214a and the fourth half split bar 214b of the second binding bar 214 are provided.

Next, a three-hole perfect circle ring binding device according to another embodiment of the present invention will be described with reference to FIGS.
The binding device 610 of this embodiment has substantially the same configuration as the binding device 210 of the above embodiment, but mainly the configuration of the holding member, the configuration of the operating member, and Since the configuration of the opening / closing member is different, the following description will be made focusing on them.

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

The binding rod is composed of three binding rods of a first binding rod 612, a second binding rod 613, and a third binding rod 614 for the three-hole type. The first binding rod 612 includes a first half split rod 612a and a second half split rod 612b, and the second binding rod 613 includes a third half split rod 613a and a fourth half split rod 613b. The third binding rod 614 includes a fifth half split rod 614a and a sixth half split rod 614b.
Then, the first half-split 612a and the second half-split are provided 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. At the leading end of the collar 612b, the distal ends of the third half split collar 613a and the fourth half split collar 613b, and the leading ends of the fifth half split collar 614a and the sixth half split collar 614b, that is, the first binding At the tops of the collar 612, the second staple 613, and the third staple 614, a staple anchoring portion 650 is formed.

The first binding rod 612, the second binding rod 613, and the third binding rod 614 constituting the binding rod are made of a metal wire having a circular cross section in a direction in which the binding pinching portion 650 is removed (O in FIG. 65). It is formed by bending in the direction of closing the binding by extending in the direction of ₁ and O ₂ and pressing the central part. The first binding rod 612, the second binding rod 613, and the third binding rod 614 are arranged in the direction in which the center opens the binding rod (the first half split rod 612a, the third half split rod 613a, and the fifth 65 swells in the O ₃ direction of FIG. 65, the second half split 612 b, the fourth half split 613 b, and the sixth half split 614 b in the O ₄ direction of FIG. Both ends are formed in a substantially bean shape with a cross section bent in the direction of closing the binding.
That is, the first binding rod 612, the second binding rod 613, and the third binding rod 612 are viewed in the opening / closing direction when the annular first binding rod 612, the second binding rod 613, and the third binding rod 614 are viewed in the opening / closing direction.

The first binding rod 612, the second binding rod 613, and the third binding rod 614 are formed in a semicircular shape on both outer sides when viewed in the direction of removing the binding rod.
Conventional cross-section round staples are vulnerable to deformation if they have a small diameter, and if they are large diameters, the cross-sectional area increases and material costs increase. Since there are many round holes in the binding hole in S, it is difficult to correspond to the binding hole of the binding object S such as paper, and the binding hole of the binding object S such as paper may be damaged.
However, if the first binding rod 612, the second binding rod 613, and the third binding rod 614 constituting the binding rod are thin, the binding of the binding rod locking portion 650 may not be successful.
Therefore, although it is desired to increase the width of the first binding rod 612, the second binding rod 613, and the third binding rod 614, the original metal wire rod can be used even if an original wire rod having a small cross-sectional area is used. I want to secure the necessary width as a binding by processing
Therefore, the binding rod according to the present invention expands the overall width by pressing the center portion of the wire rod that forms it and crushing the wire rod into a bean shape, that is, the overall width of the binding rod is reduced. The locking portion 650 is widened in the direction to be removed, so that the binding of the binding lock portion 650 can be completed completely.

The holding member 616 has a substantially rectangular shape with a length that allows the first binding rod 612, the second binding rod 613, and the third binding rod 614 to be provided at a predetermined interval, and both ends thereof, that is, cover sheets.

In this embodiment, in the longitudinal direction of the holding member 616, the first binding rod 612, the second binding rod 613, and the third binding rod 614 are suspended substantially from the outside to the inside. In this way, the first holding wall 624a and the second holding wall 624b are connected in series, and the first holding wall 624a and the second holding wall 624b are parallel and have substantially the same plate shape. In the holding space surrounded by the first holding wall 624a and the second holding wall 624b and the binding object mounting portion 622, an operation member 618 and the like described in detail later are accommodated.

In the binding object mounting portion 622 of the holding member 616, the first binding rod 612, the second binding rod 613, and the third binding rod 614 are arranged at a fixed interval (determined by Japanese Industrial Standards or the like).
