Description

  The present invention relates to an opener, and more particularly to an opener used to open a binding used for a ring binder or a ring file, for example.

  A binding tool having a plurality of binding rings is used for the ring binder and the ring file. The binding tool is attached to the inside of the cover, and a binding object such as paper is bound. The binding ring of the binding tool has two binding members that can be opened and closed, and these binding members are biased in the opening direction. A binding ring locking portion is formed on the front end side of the binding member, and the two binding members can be kept closed by being locked by the binding ring locking portion.

  In such a binding tool, there are several methods for opening and closing the binding members, but by displacing the two binding members in opposite directions along the center line between the two binding members constituting the binding ring. There is a binding tool of a type that releases the binding ring locking portion. In such a binding tool, the two binding members that are closed are sandwiched between the thumb and the index finger, and the two binding members are twisted so that they are displaced in the opposite directions, thereby releasing the binding ring locking portion. Then, the binding member can be opened. Therefore, the binding object can be bound into the binding tool by twisting the binding ring to open the binding member, inserting the binding member into the hole formed in the binding object, and closing the binding member ( Patent Document 1).

  However, as shown in FIG. 39, when a large number of objects to be bound 2 are bound into the binding tool 1, the range of the binding member 3 exposed from the objects to be bound 2 is reduced. For this reason, it is difficult to twist the binding member 3 and it is difficult to open the binding member 3.

  Therefore, a main object of the present invention is to provide an opener that can easily open a binding member of a binding tool even if a large number of objects to be bound are bound.

An opener according to the present invention includes a binding ring formed by closing a pair of openable and closable binding members, and a holding member having a length capable of providing the binding rings at intervals. An opener for opening the binding member by attaching the pair of binding members to each other by displacing the pair of binding members in directions opposite to each other along a direction connecting the binding rings provided in A base having a longitudinal direction and a pair of through-holes formed side by side in the base so that the pair of binding members penetrate at one end in the longitudinal direction of the base, When a force is applied in a direction in which the base body is inclined with respect to the tying direction, the end portions of the through holes are a pair of the binding members so that the binding members are displaced to open the binding members. It abuts a opener.
By inserting the binding member of the binding tool through the through-hole formed in the opener and applying force to the base of the opener in a direction inclined with respect to the direction of connecting the binding ring of the binding tool, the end of the through-hole of the opener The binding member is displaced in the opening direction. Since the through hole is formed on one end side in the longitudinal direction of the base body, the binding member can be opened by pushing the other end side in the longitudinal direction of the base body. Since the opener can apply a force to the binding member on the holding member side instead of the front end side of the binding member, the binding object can be bound on the opener, regardless of the amount of the binding object. The member can be opened.

In such an opener, the base is preferably formed with a hinge portion that bends along the longitudinal direction of the base at the center between the pair of through holes.
By forming the hinge portion on the base of the opener, the strength of the base can be increased and the deformation of the base can be prevented. In addition, by forming the hinge portion on the base, the through hole formed in the base can be brought into contact with the binding member at a position close to the holding member of the binding tool.

Moreover, it is preferable that a hinge part is continuously formed from the center part between a pair of through-holes to the intermediate part of the longitudinal direction of a base | substrate.
If the hinge part is formed on the entire base of the opener, the base may be bent at the hinge part when the opener is operated, and the operability may deteriorate. Therefore, by forming the hinge part from the through hole forming part to the middle part of the base and forming the tip in a flat shape, the operation part on the tip side of the base can be prevented from being bent, and the operability is improved. Can keep good.

  According to this invention, a force can be applied to the binding member on the holding member side of the binding tool by attaching the opener to the binding tool. Therefore, the binding object can be bound into the binding tool on the opener, and the binding member of the binding tool can be opened by operating the opener even when a large number of binding objects are bound. Since the opener has a base having a longitudinal direction, the opener can be operated at the end of the cover, for example, by arranging the base so as to reach the lower end of the cover from the binding member of the binding tool.

  The above object, other objects, features, and advantages of the present invention will become more apparent from the following description of the best mode for carrying out the invention with reference to the drawings.

The opener 10 according to the present invention is attached to the second binding ring 114. As shown in FIG. 4, the opener 10 includes a base 12 having a longitudinal direction with a length longer than the length between the second binding ring 114 and the lower edge of the cover. The base 12 is formed into a plate shape using, for example, a synthetic resin.
The base 12 has a left side edge and a right side edge extending from one end side on the far side in the longitudinal direction to a central portion on the near side, the left side edge and the right side edge are parallel, and one end side in the longitudinal direction. In FIG. 2, both end portions in the width direction are formed in an arc shape.
Further, at a position close to the central portion of the base body 12 in the longitudinal direction, stepped portions 14 are formed at both end portions in the width direction of the base body 12 so that the width on the other end side is narrower than one end side in the longitudinal direction of the base body 12. Formed.
In this embodiment, the width of the base 12 is longer than the width of the spine cover beyond the central portion in the longitudinal direction, and the width of the step portion 14 is substantially the same as the width of the spine cover. Is formed.

Further, on the other end side, which is the front side in the longitudinal direction of the base 12, inclined portions 16 a and 16 b whose widths are gradually narrowed are formed on both sides of the base 12 in the width direction.
An operation portion 18 extending in the longitudinal direction of the base 12 is formed on the right inclined portion 16a. The operation part 18 is formed from the terminal part of one inclined part 16a (on the right side in FIG. 2) to the other end part on the front side in the longitudinal direction of the base 12.
The operation portion 18 is connected to the inclined portion 16a so as to be recessed toward the other inclined portion 16b, so that a finger can be attached in the vicinity of the connection portion between the inclined portion 16a and the operation portion 18. Is formed. The terminal part of the operation part 18 and the terminal part of the other inclined part 16b are formed in an arc shape.

On one end side in the longitudinal direction of the base body 12, for example, two rectangular first through holes 20 and second through holes 22 are formed side by side in the width direction. One first through hole 20 is formed smaller than the other second through hole 22. Here, the base 12 is formed with a cut 24 that extends from the other second through hole 22 to the end of the second through hole 22 in the width direction of the base 12 close to the edge of the hole. The cut 24 is substantially orthogonal to the left edge of the base 12 and the left hole of the second through hole 22.
A third binding member 114 a and a fourth binding member 114 b constituting the second binding ring 114 on the near side of the binding tool 110 are inserted into the first through hole 20 and the second through hole 22. At this time, with the third binding member 114a and the fourth binding member 114b being opened, the third binding member 114a is inserted into the first through hole 20, and the fourth through hole 24 is inserted into the second through hole 22. The binding member 114b is fitted. At this time, by making the second through hole 22 larger than the first through hole 20, the length of the base 12 on both sides of the cut 24, that is, the length of the hole edge of the second through hole 22 can be increased. It is possible to easily open the cut 24 portion when the third binding member 114a is inserted.

The binding device 110 includes a first binding ring 112 that is a main binding ring that is directly opened by the opener 10 and is closed by a finger, and a secondary binding ring that is driven to operate in the closing direction of the first binding ring 112. And the right first binding member 112a and the third binding member 114a move toward the front side, and the left second binding member 112b and the fourth binding member. 114 b is configured to move toward the other side and open by the opener 10.
When the operation unit 18 on the near side of the opener 10 is pushed and rotated toward the left side, that is, the fourth binding member 114b to open the binding tool 110, the hole edge on the far side of the first through hole 20 of the opener 10 is the first edge. 3. Push the far side near the base of the third binding member 114a toward the near side, and the hole edge on the near side of the second through hole 22 of the opener 10 faces the near side near the base of the fourth binding member 114b. However, the first through hole 20 and the second through hole 22 are configured to correspond to the first through hole 20 and the second through hole 22.
When the first through hole 20 and the second through hole 22 are substantially square, the vertical length is slightly longer than the width of the second binding ring 114, and the lateral width is also closed when the second binding ring 114 is opened. It has a length that can be adapted to.
The first through-hole 20 is relatively close to the cross-sectional shape of the third binding member 114a in order to improve the operability of the opener 10 by firmly grasping and operating the third binding member 114a. Therefore, the second through hole 22 is slightly larger than the first through hole 20.
Furthermore, the first through-hole 20 and the second through-hole 22 are shifted in the longitudinal direction of the base 12 at the intersection of the diagonal lines of the substantially square holes, and the first through-hole 20 is the second through-hole. It is lowered from the hole 22 to the near side.
Thus, when the operation unit 18 on the near side of the opener 10 is pushed to the left side, the hole edge on the opposite side of the first through hole 20 on the opposite side to the pushing direction is immediately beyond the third binding member 114a. In the vicinity of the base portion on the side, the third binding member 114a can be moved to the near side so that the initial movement is accelerated. When the hole edge on the near side of the second through hole 22 hits the vicinity of the base portion on the near side of the fourth binding member 114b, the hole edge on the far side of the first through hole 20 is on the other side of the third binding member 114a. Delayed when hitting the vicinity of the base.

  Further, an arrow-shaped hole 26 extending in the width direction of the base body 12 is formed on the other end side in the longitudinal direction of the base body 12. The arrow-shaped hole 26 is formed so as to go from the operation unit 18 side to the opposite side in the width direction of the base 12. Further, the base body 12 is formed with a hinge portion 28 formed so as to be bent along the longitudinal direction. The hinge portion 28 is formed so as to pass through the central portion between the two first through holes 20 and the second through hole 22, that is, the central portion in the width direction of the base 12. The hinge portion 28 is formed from one end in the longitudinal direction of the base 12 to the arrow-shaped hole 26, and no hinge portion is formed from the arrow-shaped hole 26 to the other end in the longitudinal direction of the base 12. As shown in FIG. 5, the hinge portion 28 has a mountain shape in which the first through hole 20 and the second through hole 22 are arranged below when viewed from the operation portion 18 side, and on the center line of the holding member 116.

However, the B-side through-hole 126a and the B-side through-hole 128a are locked by the weight of the binding object S to which the binding ring locking portion 150 of the first binding member 112a in the locked state is bound. When the first binding ring 112 and the second binding ring 114 are closed, the distance L2 is shorter than the distance L1 so that the movement in the direction O1 from which the portion 150 is removed can be restricted. It is comprised so that it may become.

When the binding rings 112 and 114 are closed and the binding rings are twisted to open the binding rings 112 and 114, one binding member (the first binding member 112a and the third binding member 114a) is bound. The other binding member (the second binding member 112b and the fourth binding member 114b) disengages the binding ring locking portion 150 while moving to the near side, which is the side from which the ring locking portion 150 is disengaged. One through-hole (B-side through-hole 126a, B-side through-hole) through which one binding member (first binding member 112a, third binding member 114a) is inserted in order to move to the other side. 128a) is formed so as to allow movement of one binding member (first binding member 112a, third binding member 114a), and the other binding member (second binding member 112b, fourth binding member). 114b) The through hole of the (A-side through holes 126b, A-side through hole 128b) is formed so as to permit movement of the other binding member (the second binding member 112b, a fourth binding member 114b).
The movement restricting portion is formed so as to allow movement of one binding member (first binding member 112a, third binding member 114a), and the other binding member (second binding member 112b, fourth binding member). It is formed to allow movement of member 114b).
Then, an overload is applied only to the binding rings 112 and 114 in a direction in which the binding ring locking portion 150 of one binding member (the first binding member 112a and the third binding member 114a) of the binding object S is disengaged. When applied, the one through hole (B side through hole 126a, B side through hole 128a) inserted through one binding member (first binding member 112a, third binding member 114a) is one binding. One binding member (first binding member 112a, third binding member 114a) moved to the side of disengaging the binding ring locking portion 150 of the members (first binding member 112a, third binding member 114a). ) And the other through-hole (A-side through-hole 126b, A-side through-hole) inserted through the other binding member (second binding member 112b, fourth binding member 114b). Hole 128b) is the other binding The second binding member 112b and the fourth binding member 114b are allowed to further move toward the stopped one binding member (the first binding member 112a and the third binding member 114a). And the movement restricting portion is moved to the side where the binding ring locking portion 150 of one of the binding members (the first binding member 112a and the third binding member 114a) is disengaged. It is formed to allow the other binding member (second binding member 112b, fourth binding member 114b) to move further toward the members (first binding member 112a, third binding member 114a). Has been.

  In the binding ring locking portion 150, the locking convex portions (the convex portions 152a and the convex portions 156a) of one binding member (the first binding member 112a and the third binding member 114a) protrude toward the other side. In addition, the locking convex portions (the convex portions 154a and the convex portions 158a) of the other binding member (the second binding member 112b and the fourth binding member 114b) protrude toward the front side, and the binding ring locking portion 150. When the binding ring which is disengaged and is closed is twisted and opened, the locking convex portions (the convex portions 152a and the convex portions 156a) of one binding member (the first binding member 112a and the third binding member 114a) are opened. ) Is moved in the direction opposite to the direction in which the first binding member protrudes, the first binding member 112a and the third binding member 114a are moved, and the other binding member (second binding member 112b and fourth binding member). The locking protrusion (protrusion) of the binding member 114b) 54a, the convex portion 158a) is moved in the direction opposite to the protruding direction, the other binding member (second binding member 112b, fourth binding member 114b) is moved, and one binding member (first binding member The locking projections (projections 152a, 156a) of the binding member 112a and the third binding member 114a are used as the locking recesses (second binding member 112b, fourth binding member 114b) of the other binding member. The engaging projections (projections 154a and 158a) of the other binding member (second binding member 112b and fourth binding member 114b) are disengaged from the recesses 154b and 158b). The first binding member 112a and the third binding member 114a) can be disengaged from the locking concave portions (the concave portion 152b and the concave portion 156b).

A force is applied with a finger in a direction in which the base body 12 is inclined, and the base portions of the first binding ring 112 and the second binding ring 114 are twisted by the opener 10, whereby the binding ring locking portion 150 of the second binding ring 114 is moved. When removed, the first working piece 130 and the second working piece 132 have a force that the twisted opening and closing member 140 tries to return to the original state, that is, one first erection part 144 and the other second part. As shown in the direction of the arrows in FIGS. 6B and 6C, the erection portion 146 rotates in the circumferential direction of the connecting portion 142 so as to return to the original state. The binding ring 112 is opened.
Further, the first binding ring 112 and the second binding ring 114 have the binding ring locking portion 150 removed (see FIG. 11), and the first operating piece 130 and the second operating piece 132 are connected to the binding ring. It moves in the direction in which the locking portion 150 is disengaged (the first operating piece 130 is in the O1 direction and the second operating piece 132 is in the O2 direction) (see FIG. 14A). As a result, the restriction convex portion 130g of the first working piece 130 constituting the movement restricting portion moves in the restriction concave portion 132f of the second working piece 132, and the binding ring locking portion 150 in the restriction concave portion 132f is released. The regulating convex part 132g of the second working piece 132 that hits the edge opposite to the side and that constitutes the movement regulating part moves in the regulating concave part 130f of the first working piece 130 and binds in the regulating concave part 130f. It abuts against the edge opposite to the direction of the ring locking portion 2 (see FIG. 14B).
When the rotating force of the opener 10 is removed or weakened, the first binding ring 112 and the second binding ring 114 are connected to the first opening / closing member 140 when the force for releasing or twisting the first binding ring 112 is reduced. As shown in the arrow directions in FIGS. 10B and 10C, the erection portion 144 and the second erection portion 146 rotate in the circumferential direction of the connecting portion 142 to generate a force for returning to the original state. By acting on the working piece 130 and the second working piece 132, the first working piece 130 and the second working piece 132 are changed from the flat state to the mountain folded state and further opened (the first binding member 112a and the second working piece 132). The third binding member 114a is in the O3 direction, the second binding member 112b and the fourth binding member 114b are in the O4 direction), and the first erection portion 144 and the second erection portion 146 of the opening / closing member 140 are returned to the original state. The first by trying And Dohen 130 and the second operating piece 132, moves in the opposite direction (see FIG. 18 (A) (B)).
That is, the actuating member 118 and the opening / closing member 140 act in a direction to open the convex portion 156a of the third binding member 114a and the convex portion 158a of the fourth binding member 114b constituting the second binding ring 114, and The first binding ring 112 acts in a direction to separate the convex portion 152a of the first binding member 112a and the convex portion 154a of the second binding member 112b, and the third binding ring 114 constitutes the third binding ring 114. The convex portion 156a of the binding member 114a acts to separate the convex portion 158a of the fourth binding member 114b.

  As described above, in this embodiment, the operation unit 18 is configured so that the base of the first binding ring 112 or the second binding ring 114 faces leftward (in the direction intersecting with the lines X1 and X2) to incline the base body 12. The first binding member 112a of the first binding ring 112 and the second binding member 112b of the first binding member 112b are locked by pushing with a finger, that is, applying a force to the opener 10 (shown in FIG. 7) and twisting with the opener 10. The binding ring locking portion 150 of the portion 150 and the third binding member 114a and the fourth binding member 114b of the second binding ring 114 can be removed.

  The first binding member 112a and the second binding member 112b of the first binding ring 112 and the third binding member 114a and the fourth binding member 114b of the second binding ring 114 are also shown. When the engagement of the binding ring locking portion 150 is released and the twisting force by the opener 10 is removed or weakened, the first erection portion 144 and the second erection portion 146 of the opening / closing member 140 are connected in the circumferential direction of the connecting portion 142. , The actuating member 118 is allowed to move in the same direction (that is, the force to return to the original state in which no force is applied to the opening / closing member 140), whereby the actuating member 118 has the butt edge 130a of the first actuating piece 130. And the butting edge 132a of the second working piece 132 are pivoted by a force to return to the connection portion 142 and to return to the first installation portion 144 and the second installation portion 146. The first operating piece 130 and the second operating piece 132 is moved in the opposite direction, and the edge 132a abutting the abutting edge 130a rises in the direction of projecting the binding ring, the mountain fold state by.

  As shown in FIGS. 1 and 3, the opener 10 of the present invention is attached to the second binding ring 114 of such a binding tool 110. At this time, with the third binding member 114a and the fourth binding member 114b open, the third binding member 114a is inserted into the first through hole 20 and the second through hole 22 is inserted into the second through hole 22 through the cut 24. Four binding members 114b are fitted. In this way, by attaching the opener 10 to the second binding ring 114, the base 12 of the opener 10 is arranged so as to extend in the longitudinal direction of the holding member 116 of the binding tool 110. The base 12 is formed to a length that reaches the vicinity of the lower end of the cover CO when the opener 10 is attached to the second binding ring 114.

  When the opener 10 is attached to the second binding ring 114, the base 12 is formed along the holding member 116 due to the formation of the hinge portion 28 on the base 12, and the first through hole 20 and the second through hole are formed. 22 is arranged at a position close to the holding member 116. Accordingly, the first through hole 20 and the second through hole 22 of the opener 10 are disposed at the base portions of the third binding member 114a and the fourth binding member 114b.

  The smaller first through hole 20 is preferably formed to have a size close to the cross-sectional shape of the third binding member 114a. By forming such a size, it is possible to prevent the base 12 from wobbling in the first through hole 20 portion. Further, in a state where the base 12 is arranged so as to extend in the longitudinal direction of the holding member 116 of the binding tool 110, the end portion of the first through hole 20 that is small on the first binding ring 112 side is the third binding. The two first through holes 20 and the second through holes 22 are formed so that the end of the large second through hole 22 is in contact with the member 114a and the end of the large second through hole 22 is in contact with the fourth binding member 114b. Is done.

  In this state, an object to be bound such as paper is bound onto the opener 10 by the first binding ring 112 and the second binding ring 114. Then, by placing a hand on the operation unit 18 and applying a force in the direction of the arrow-shaped hole 26, the base 12 is displaced so as to be inclined with respect to the longitudinal direction of the holding member 116. As a result, as shown in FIGS. 6 and 7, the third binding member 114a and the fourth binding member 114b are in contact with the end portions of the first through hole 20 and the second through hole 22, respectively. The member 114a and the fourth binding member 114b are displaced in the opposite directions along the center line of the holding member 116 therebetween. By such a displacement, as shown in FIG. 8, the binding ring locking portion 150 of the second binding ring 114 is released, and the third binding member 114a and the fourth binding member 114b are opened. Since the first binding ring 112 is interlocked with the second binding ring 114, the first binding member 112 a and the second binding member 112 b are also opened by operating the opener 10.

  In this way, by using this opener 10, the first binding ring 112 and the second binding ring 112 and the second binding ring 112 can be easily applied by applying a force to the operation portion 18 of the base 12 extending to the vicinity of the lower end portion of the cover CO. The binding ring 114 can be opened. Therefore, it is not necessary to operate the binding ring on the object to be bound, and a large number of objects to be bound can be bound into the first binding ring 112 and the second binding ring 114.

  In addition, the strength of the base body 12 can be increased by forming the hinge portion 28 on the base body 12. However, if the hinge portion is formed in the entire longitudinal direction of the base 12, when the force is applied to the operation portion 18, the bending of the base 12 at the hinge portion increases, and the operability may deteriorate. However, in this opener 10, since no hinge portion is formed between the arrow-shaped hole 26 and the other end portion in the longitudinal direction of the base body 12, further bending of the base body 12 at the operation portion 18 can be prevented. it can.

  Furthermore, if the hinge portion 28 and the portion where the hinge portion is not formed are continuous, a force for the hinge portion 28 to return to a flat shape acts, but the hinge portion 28 and the hinge portion are formed by the arrow-shaped hole 26. By separating the portion that is not provided, it is possible to prevent such a force from acting on the hinge portion 28. Therefore, the effect that the strength of the base 12 is increased by the hinge portion 28 can be obtained, and the effect that a good operability can be obtained by the operation portion 18 forming portion where the hinge portion is not formed can be obtained.

  Further, in this opener 10, since the operation part 18 is formed along the longitudinal direction of the base 12, the inclined part 16a is continuously formed when a force is applied to the operation part 18 by applying a finger. Compared to the case where the finger is slippery.

  Further, the base 12 is formed to have different widths with the stepped portion 14 as a boundary, but the portion with a large width is a width that is sandwiched between the front cover and the back cover when the cover CO is closed. It is preferable to be formed. By setting it as such a width | variety, the base | substrate 12 is fixed by the front cover and back cover in the vicinity of the 2nd binding ring 114, and the opener 10 can be stabilized. However, when the base 12 is formed to have the same width, the opener 10 may be inclined with respect to the spine by being sandwiched between the front cover and the back cover on the lower end side of the cover CO. In such a case, since the object to be bound may be damaged by the inclined opener 10, the width of the base 12 is narrowed on the lower end side of the cover CO so that it does not come into contact with the front cover and the back cover. .

  In addition, as a shape of the 1st through-hole 20 and the 2nd through-hole 22, it can change into arbitrary shapes, such as not only square shape but circular shape. Regardless of the shape of the first through hole 20 and the second through hole 22, on the opposite side of the holding member 116 in the longitudinal direction, the end portions of the first through hole 20 and the second through hole 22 are the third binding member 114a and By setting the state in contact with the fourth binding member 114b, the first binding ring 112 and the second binding ring 114 can be opened without greatly displacing the opener 10. That is, the initial operation when opening the first binding ring 112 and the second binding ring 114 can be accelerated.

  As shown in FIGS. 23, 24 and 25, the opener 10 can also be used for a binding tool 110 using large D-shaped binding rings 512 and 524. Since such a binding tool 110 is attached to the inside of the back cover of the front cover CO, when the opener 10 is attached to the binding tool 110, the opener 10 is not sandwiched between the front cover and the back cover. Therefore, as shown in 26, the base body 12 having no stepped portion can be used.

Further, the outer shape of the opener 10 may be tapered in a plan view from the far side of the base 12 to the near side as shown in FIGS. 27 to 33, for example, and is an area extending from the central portion of the base 12 to the near side. Only a taper shape may be used.
Further, the opener 10 may be formed as a synthetic resin molded article as a whole in a flat plate shape, and may be bent by applying Thomson processing at a portion where the hinge portion 28 is formed. The hinge plate 28 may be formed by first forming a flat plate as a press-processed product into a flat plate shape and then bending the portion where the hinge portion 28 is to be formed.
Further, as shown in FIG. 35, the base 12 may be attached to the first binding ring 112 so that the base 12 extends toward the other side.
As shown in FIG. 36, the base 12 may extend in a direction orthogonal to the holding member, that is, in a direction in which the second binding ring 114 opens.
