Description

  The present invention relates to a binding tool, and more particularly to a binding tool for operating an operation member such as an operation lever to insert a binding object such as a document into a file / binder.

As a conventional binding tool as a background of the present invention, Japanese Patent No. 4755115 and Japanese Patent No. 5123969 disclose that the operation lever is pushed down against the elastic force of the torsion spring, respectively. In some cases, a binding object is sandwiched between a binding member interlocking with the substrate and a substrate facing the binding member (Patent Document 1 and Patent Document 2).
In the binding tool disclosed in Patent Document 1, the binding member is formed by being bent into a complicated shape, and one end of the torsion spring is supported by the binding member.
Further, the binding tool disclosed in Patent Document 2 includes a pivot portion for rotating the binding member between a holding state in which the binding member presses the binding object and an open state in which the binding member is separated from the binding object, and a part of the spring. Is extended toward the pressing portion of the binding member and is operated to rotate between the hold state and the open state, and slides in the direction in which the pivot portion extends when the binding member is moved from the hold state to the open state. It is comprised so that it may operate.

It is desired that the back cover of the file binder is narrow, and it is desirable to reduce the height of the binding tool accordingly. In the binding tool disclosed in Patent Document 1, as shown in FIGS. 9 and 13 of Patent Document 1, the binding member is bent in a complicated manner to support the spring member, and the object to be bound is a spring. It is pressed closer to the note alignment part than the tip of the member. For this reason, when the binding tool of Patent Document 1 is lowered, the portion where the binding member presses the object to be bound becomes close to the outer edge of the object to be bound, and the stability of pressing of the object to be bound becomes a problem.
On the other hand, as shown in FIGS. 6B and 12 of Patent Document 2, the binding tool disclosed in Patent Document 2 has a structure in which the object to be bound is pressed by the front end portion of the binding member. However, in the binding tool disclosed in Patent Document 2, since the spring member has a structure that presses the binding member at the root portion of the binding member, it is separated from the front end of the binding member that is the portion that holds the object to be bound. For this reason, when the binding tool of Patent Document 1 is lowered, there is a possibility that a problem may occur in the stability of pressing of the object to be bound.

At the same time, the object to be bound X is pressed with the same pressing force.
The first support convex portion 92a and the second support convex portion 92b are formed by protruding the binding member support portions (the first binding member support portion 30 and the second binding member support portion 34) on the base plate 22 as the base member. In this state, the first support convex portion 92a is inserted into the holding hole 32 and the second support convex portion 92b is formed into the hole so that it can be inserted into the respective holes from the tips of the hanging portions 96. Has been.

In this embodiment, since the binding member 70 is arranged closer to the operation lever 60 side, the interval between the bearing portion 38 and the first binding member support portion 30 and the second binding member support portion 34 is narrowed. Before inserting the first support convex portion 92a into the holding hole 32 and the second support convex portion 92b into the holding hole 36, the bearing portion 38 is connected to the first binding member support portion 30 and the second binding member. It is slightly tilted toward the first binding member support portion 30 so as to be separated from the support portion 34 (see FIG. 11A).
The first binding member support portion 30 and the second binding member support portion 34 are raised from the substrate 22 toward the arrangement side of the binding member 70 and are erected so as to be perpendicular to the main surface of the substrate 22 ( (See FIG. 11A).

The bearing portion 38 that has been slightly tilted is raised so as to be perpendicular to the main surface of the substrate 22 after the binding member 70 is connected to the first binding member support portion 30 and the second binding member support portion 34. (See FIG. 11C).

  Further, a single protrusion 42 is formed on the other end side (right end) of the substrate 22 in the width direction. The ridges 42 are formed in parallel at an appropriate distance in the width direction of the substrate 22. A pair of substrate fixing through holes 44 for attaching the binding tool 20 to a file or the like are formed on both sides in the longitudinal direction of the substrate 22 on the opposite side and the near side, and a hook is fitted into the substrate fixing through hole 44. The binding tool 20 is attached to a file or the like.

[Binding mechanism for the object to be bound]
A shaft 58 is inserted through the pivot fixing through hole 26 of the bearing plate 24 and the through hole 40 of the bearing portion 38, and a spring member 50 made of a torsion coil spring and an operation lever 60 as an operation member are attached to the shaft 58.
The operation lever 60 includes a lock mechanism for bringing the operation lever 60 into a locked state on the substrate 22.
The lock mechanism includes an engagement body 120 provided on the operation lever 60 side (opposite side to the bearing plate 24), an engagement body support portion 180 to which the engagement body 120 is attached, and a protrusion provided on the operation lever 60. Part 100 is provided.

A part of the spring member 50 that is the biasing member extends from the operation lever 60 side that is the operation member toward the pressing portion 72 of the binding member 70, and the spring member 50 that is the operation member of the binding member 70 is centered on the operation lever 60 side. It operates so that it moves to the hold state which presses the binding object X, and the open state which leaves | separates from the binding object X.
The binding member 70 has a width direction extending from the operation lever 60 side serving as the operation member, and an edge of the binding member 70 on the side opposite to the operation lever 60 serving as the operation member when the binding member 70 is viewed in plan view. The pressing portion 72 is provided on a straight line that is substantially the same as the straight line SL ₁ including the edge portion of the binding member 70. located in the vicinity of the straight line SL ₁ containing, and are located in the vicinity of the center in the longitudinal direction of the binding member.
The spring member 50 includes a winding portion 52 wound around an outer periphery of a shaft 58, a spring first end portion 56 extending from one end (right end portion) of the winding portion 52 toward the binding member 70, and the winding portion. 52 has a spring second end portion 54 linearly extending from the other end (left end portion) on the bearing plate 24 side to the operation lever 60 side.
The shaft 58 and the winding portion 52 of the spring member 50 are bridged between the bearing plate 24 and the bearing portion 38 so as to cross the bearing plate 24 obliquely.
The part (spring first end portion 56) of the spring member 50 as the urging member is opened and closed so as to open and close from a hold state where the binding member 70 presses the binding object X to an open state away from the binding object. When the operation lever 60 which is an operation member is operated, it is formed to move in the upward direction, that is, the direction in which the bearing plate 24 rises.
A part of the spring member 50 (spring first end portion 56) extends toward the pressing portion 72 of the binding member 70, and the holding state in which the binding member 70 presses the object X to be bound and an open state away from the object to be bound. In order to open and close to the state, it is configured to rotate around the engaging portion 90.

  The spring second end portion 54 of the spring member 50 extends linearly from the upper end of the rear side on the bearing plate 24 side of the winding portion 52 to the near side, and when the tip is not subjected to external force, the tip is on the near side. It is formed so as to extend obliquely upward.

The spring first end portion 56 includes a spring rising portion 56a that extends from the lower end on the front side of the winding portion 52 to the opposite side of the bearing plate 24 on the bearing portion 38 side of the winding portion 52, and is substantially L-shaped when receiving no external force. Thus, a spring spanning portion 56b extends obliquely downward from the upper end of the spring rising portion 56a that extends upward, and a spring locking portion 56c is formed on the free end side of the spring spanning portion 56b.
The spring first end portion 56 where the external force does not act and the spring second end portion 54 (particularly the rising portion 50b) where the external force does not act are separated and expanded from the winding portion 52 toward the tip thereof. It is formed in an approximately eight-letter shape.

A shaft 58 for fixing the operation lever 60 and the spring member 50 to the substrate 22 is disposed between the center m in the longitudinal direction of the binding member 70 and the far side edge, and the shaft 58 is connected to the binding member 70. It is arrange | positioned in the vicinity of the center m, ie, the 1st biasing member accommodating part 80, rather than the said far side edge in the longitudinal direction. The center m in the longitudinal direction of the binding member 70 refers to the center of a line connecting the far side edge and the near side edge of the binding member 70.
The spring member 50 has a corner portion 56 d that is bent substantially at a right angle at a first end portion 56 extending from the winding portion 52 to the binding member 70. When the binding tool 20 is in the hold state, the spring rising portion 56a from the winding portion 52 to the corner portion 56d of the spring member 50 is parallel to the longitudinal direction of the binding tool 20 and is a spring that is the tip of the spring member 50. The spring spanning portion 56b from the locking portion 56c to the corner portion 56d is parallel to the width direction of the binding tool 20.
A length L ₁ from the corner portion 56d to the center of the winding portion 52 (that is, approximately the same length as the spring rising portion 56a) is equal to the straight line SL _{2 in} the extending direction of the shaft 58 and the binding member 70. it is substantially the same as the length L ₂ between the center line in the longitudinal direction (see FIG. 12B).
The center line in the longitudinal direction of the binding member 70 refers to a straight line SL ₄ in the width direction of the binding member 70 passing through the center m (the center of the line connecting the far side edge and the near side edge of the binding member 70).

The substrate 22 is formed at a position slightly shifted to the far side of the bearing plate 24 as a shaft fixing portion that pivotally supports one end of the shaft 58 and the pivot fixing through hole 26 of the bearing plate 24, and the other end of the shaft 58. And a bearing portion 38 that is a shaft fixing portion that supports the shaft.
The shaft 58 spanned and fixed between the pivot fixing through hole 26 of the bearing plate 24 and the through hole 40 of the bearing portion 38 has a bearing portion 38 side which is the binding member 70 side of the shaft 58. At the position rotated on the horizontal plane in the direction away from the free end of the operation lever 60 around the plate 24 side, it is fixed to the through hole 40 of the bearing portion 38.

The shaft 58 that fixes the operating lever 60 and the spring member 50 to the substrate 22 has an inclination between the straight line SL ₂ extending in the axial direction of the shaft 58 and the straight line on the central axis SL ₃ of the winding portion 52 of the spring member 50. It can be changed between the hold state and the open state (see FIGS. 12A (A) and 12 (B)).
That is, a slight gap is provided between the inner diameter of the winding portion 52 and the outer diameter of the shaft 58. Further, the length from the bearing plate 24 to the bearing portion 38 of the substrate 22 is relative to the width of the winding portion 52 in the central axis direction of the winding portion 52 (the width of the winding portion 52 in the width direction of the binding tool 20). And it is provided enough. With such a configuration, the winding portion 52 can be inclined with respect to the direction in which the shaft 58 extends.

Here, a case in which the central axis of the winding portion 52 of the spring member 50 cannot be changed in inclination with respect to the shaft 58 will be described in comparison.
When the binding tool 20 is in the hold state, the spring spanning portion 56b is substantially parallel to the central axis of the winding portion 52, that is, the shaft 58, and the spring spanning portion 56b binds the binding tool 20 in plan view. It is located at the center of the member 54 and is inserted through the through hole 78.
When the binding tool 20 moves from the hold state to the open state, the spring spanning part 56b rotates around the central axis of the winding part 52, that is, the shaft 58, and slightly moves to the upper right when the binding tool 20 is viewed from the right side. Moving.
On the other hand, when the binding tool 20 moves from the hold state to the open state, the binding member 70 has a pair of first and second support protrusions 92a and 92b. The binding tool 20 is moved directly upward as viewed from the right side as it rotates about the line connecting the two.
However, when the central axis of the winding portion 52 of the spring member 50 cannot change the inclination with respect to the shaft 58, the binding tool 20 is held between the spring bridge portion 56 b of the spring member 50 and the through hole 78 of the binding member 70. Since the moving direction when moving from the state to the open state is different, the spring bridge portion 56b and the through hole 78 are maintained when the spring bridge portion 56b moves from the open state to the hold state while maintaining the state where the spring bridge portion 56b is inserted through the through hole 78. There is a risk that a load will be applied at the contact part. Therefore, smooth movement may be difficult in the open state and the hold state.
However, since the binding tool 20 of the present invention is configured to be able to change the inclination of the central axis of the winding portion 52 with respect to the shaft 58, even when the binding tool 20 moves from the hold state to the open state, The central axis of the winding portion 52 of the spring member 50 moves in accordance with the movement of the binding tool from the right side to the position directly above the through hole 78, and the spring member 50 is maintained in a state where the spring member 50 is inserted through the through hole 78. The binding tool 20 can smoothly move from the hold state to the open state without applying a large load at the contact portion between the transfer portion 56b and the through hole 78.

A shaft 58 for fixing the operation lever 60 and the spring member 50 to the substrate 22 is disposed between the center m in the longitudinal direction of the binding member 70 and the far side edge, and the shaft 58 is connected to the binding member 70. Is arranged in the vicinity of the center m, that is, in the vicinity of the first biasing member accommodating portion 80, with respect to the far side edge in the longitudinal direction. Here, it is assumed that the shaft 58 is the center in the longitudinal direction of the binding member 70. Instead, the case where it is arranged in the vicinity of the far side edge will be described in comparison.
When arranged in the vicinity of the far side edge, the length from the straight line in the extending direction of the shaft 58 to the center line in the longitudinal direction of the binding member 70 becomes large, so that the length is substantially the same as that length. Thus, the length L ₁ from the corner portion 56d to the center of the winding portion 52 (that is, approximately the same length as that of the spring rising portion 56a) is also a large binding tool.
As described above, when the binding tool 20 has a configuration in which the inclination of the central axis of the winding portion 52 with respect to the shaft 58 cannot be changed, the spring bridging portion 56b is opened from the hold state to the binding tool 20. when moving, rotating about a central axis or axis 58 of the winding unit 52, it will move slightly to the upper right looking at the binding device 20 from the right, the center axis SL ₃ of the winding portion 52 When the length L ₁ (radius L ₁ ) from the corner portion 56d increases, the distance to the upper right when the binding tool 20 is viewed from the right side increases accordingly. Even if the inclination of the central axis of the winding portion 52 can be changed with respect to the shaft 58, the winding portion 52 needs to be greatly inclined as the moving distance increases. Since there is a limit to the inclination of the winding portion 52, a large load is applied to the contact portion of the spring bridging portion 56b and the through hole 78 when the binding tool 20 moves from the hold state to the open state.
However, in the binding tool 20 of the present invention, the shaft 58 is disposed at the center m, that is, in the vicinity of the first urging member accommodating portion 80 with respect to the far side edge in the longitudinal direction of the binding member 70, and the winding portion Since the length L ₂ (radius L ₁ ) from the central axis of 52 to the corner portion 56d is reduced, the binding tool 20 can be smoothly applied without applying a large load at the contact portion between the spring bridging portion 56b and the through hole 78. Makes it possible to move from the hold state to the open state.

In the spring member 50, the winding portion 52 is mounted substantially parallel to the substrate 22 around the axis of the shaft 58 between the bearing plate 24 and the bearing portion 38 as the shaft fixing portion, and the second end of the spring where the external force does not act. The portion 54 extends in the longitudinal direction of the substrate 22 along the inner side of the bearing plate 24, and is fixed to the operation lever 60 substantially parallel to the longitudinal direction of the operation lever 60.
That is, the spring second end portion 54 to which the external force does not act pushes the operation lever 60 so as to release the lock from the locked state in order to set the hold state for pressing the binding object X and the open state away from the binding object. It is fixed to the operation lever 60 along the rotating direction, that is, along the track surface on which the operation lever 60 rotates. Therefore, the spring member 50 can move smoothly without unnecessary interference, and the movement of the operation lever 60 such as raising and lowering becomes smooth.

When the operating lever 60 is rotated to bring the binding member 70 into a hold state (locked state) in which the binding object X is pressed and to an open state (unlocked state) away from the binding object X, that is, to open and close In addition, the spring first end portion 56 of the spring member 50 rotates, but the winding portion 52 contracts or loosens accordingly. Therefore, the inner diameter of the winding part 52 is configured so that a gap is provided slightly between the outer diameter of the shaft 58. The winding portion 52 is wound on the outer peripheral surface of the shaft 58.
That is, the winding portion 52 extends from the spring second end portion 54 side toward the spring first end portion 56 side so as to obliquely intersect the longitudinal direction of the operation lever 60, and the spring first end of the spring member 50. The portion 56 side is fixed to the substrate 22 at a position farther from the spring second end portion 54 side.
When no external force acts on the spring member 50, the spring second end portion 54 is formed so as to push up the free end of the operation lever 60 with the shaft 58 as a pivot portion, and the spring first end portion 56 forms the binding member 70 on the substrate.

The lock mechanism includes an engagement body 120 provided on the operation lever 60 side (opposite side to the bearing plate 24), an engagement body support portion 180 to which the engagement body 120 is attached, and a protrusion provided on the operation lever 60. Part 100 is provided.

A part of the spring member 50 that is the biasing member extends from the operation lever 60 side that is the operation member toward the pressing portion 72 of the binding member 70, and the spring member 50 that is the operation member of the binding member 70 is centered on the operation lever 60 side. It operates so that it moves to the hold state which presses the binding object X, and the open state which leaves | separates from the binding object X.
The binding member 70 has a width direction extending from the operation lever 60 side serving as the operation member, and an edge of the binding member 70 on the side opposite to the operation lever 60 serving as the operation member when the binding member 70 is viewed in plan view. The pressing portion 72 is provided on a straight line that is substantially the same as the straight line SL ₁ including the edge portion of the binding member 70. located in the vicinity of the straight line SL ₁ containing, and are located in the vicinity of the center in the longitudinal direction of the binding member.
The spring member 50 includes a winding portion 52 wound around an outer periphery of a shaft 58, a spring first end portion 56 extending from one end (right end portion) of the winding portion 52 toward the binding member 70, and the winding portion. 52 has a spring second end portion 54 linearly extending from the other end (left end portion) on the bearing plate 24 side to the operation lever 60 side.
The shaft 58 and the winding portion 52 of the spring member 50 are bridged between the bearing plate 24 and the bearing portion 38 so as to cross the bearing plate 24 obliquely.
The part (spring first end portion 56) of the spring member 50 as the urging member is opened and closed so as to open and close from a hold state where the binding member 70 presses the binding object X to an open state away from the binding object. When the operation lever 60 which is an operation member is operated, it is formed to move in the upward direction, that is, the direction in which the bearing plate 24 rises.
A part of the spring member 50 (spring first end portion 56) extends toward the pressing portion 72 of the binding member 70, and the holding state in which the binding member 70 presses the object X to be bound and an open state away from the object to be bound. In order to open and close to the state, it is configured to rotate around the engaging portion 90.

  The spring second end portion 54 of the spring member 50 extends linearly from the upper end of the rear side on the bearing plate 24 side of the winding portion 52 to the near side, and when the tip is not subjected to external force, the tip is on the near side. It is formed so as to extend obliquely upward.

The spring first end portion 56 includes a spring rising portion 56a that extends from the lower end on the front side of the winding portion 52 to the opposite side of the bearing plate 24 on the bearing portion 38 side of the winding portion 52, and is substantially L-shaped when receiving no external force. Thus, a spring spanning portion 56b extends obliquely downward from the upper end of the spring rising portion 56a that extends upward, and a spring locking portion 56c is formed on the free end side of the spring spanning portion 56b. Furthermore, the spring first end portion 56 is formed with a spring bent portion 56e in which the spring bridging portion 56b is bent at a slight angle.
The spring first end portion 56 where the external force does not act and the spring second end portion 54 (particularly the rising portion 50b) where the external force does not act are separated and expanded from the winding portion 52 toward the tip thereof. It is formed in an approximately eight-letter shape.

A shaft 58 for fixing the operation lever 60 and the spring member 50 to the substrate 22 is disposed between the center m in the longitudinal direction of the binding member 70 and the far side edge, and the shaft 58 is connected to the binding member 70. It is arrange | positioned in the vicinity of the center m, ie, the 1st biasing member accommodating part 80, rather than the said far side edge in the longitudinal direction. The center m in the longitudinal direction of the binding member 70 refers to the center of a line connecting the far side edge and the near side edge of the binding member 70.
The spring member 50 has a corner portion 56 d that is bent substantially at a right angle at a first end portion 56 extending from the winding portion 52 to the binding member 70. When the binding tool 20 is in the hold state, the spring rising portion 56a from the winding portion 52 to the corner portion 56d of the spring member 50 is parallel to the longitudinal direction of the binding tool 20 and is a spring that is the tip of the spring member 50. The spring spanning portion 56b from the locking portion 56c to the corner portion 56d is parallel to the width direction of the binding tool 20.
A length L ₁ from the corner portion 56d to the center of the winding portion 52 (that is, approximately the same length as the spring rising portion 56a) is equal to the straight line SL _{2 in} the extending direction of the shaft 58 and the binding member 70. it is substantially the same as the length L ₂ between the center line in the longitudinal direction (see FIG. 12B).
The center line in the longitudinal direction of the binding member 70 refers to a straight line SL ₄ in the width direction of the binding member 70 passing through the center m (the center of the line connecting the far side edge and the near side edge of the binding member 70).

The substrate 22 is formed at a position slightly shifted to the far side of the bearing plate 24 as a shaft fixing portion that pivotally supports one end of the shaft 58 and the pivot fixing through hole 26 of the bearing plate 24, and the other end of the shaft 58. And a bearing portion 38 that is a shaft fixing portion that supports the shaft.
The shaft 58 spanned and fixed between the pivot fixing through hole 26 of the bearing plate 24 and the through hole 40 of the bearing portion 38 has a bearing portion 38 side which is the binding member 70 side of the shaft 58. At the position rotated on the horizontal plane in the direction away from the free end of the operation lever 60 around the plate 24 side, it is fixed to the through hole 40 of the bearing portion 38.

The shaft 58 that fixes the operating lever 60 and the spring member 50 to the substrate 22 has an inclination between the straight line SL ₂ extending in the axial direction of the shaft 58 and the straight line on the central axis SL ₃ of the winding portion 52 of the spring member 50. It can be changed between the hold state and the open state (see FIGS. 12A (A) and 12 (B)).
That is, a slight gap is provided between the inner diameter of the winding portion 52 and the outer diameter of the shaft 58. Further, the length from the bearing plate 24 to the bearing portion 38 of the substrate 22 is relative to the width of the winding portion 52 in the central axis direction of the winding portion 52 (the width of the winding portion 52 in the width direction of the binding tool 20). And it is provided enough. With such a configuration, the winding portion 52 can be inclined with respect to the direction in which the shaft 58 extends.

In the spring member 50, the winding portion 52 is mounted substantially parallel to the substrate 22 around the axis of the shaft 58 between the bearing plate 24 and the bearing portion 38 as the shaft fixing portion, and the second end of the spring where the external force does not act. The portion 54 extends in the longitudinal direction of the substrate 22 along the inner side of the bearing plate 24, and is fixed to the operation lever 60 substantially parallel to the longitudinal direction of the operation lever 60.
That is, the spring second end portion 54 to which the external force does not act pushes the operation lever 60 so as to release the lock from the locked state in order to set the hold state for pressing the binding object X and the open state away from the binding object. It is fixed to the operation lever 60 along the rotating direction, that is, along the track surface on which the operation lever 60 rotates. Therefore, the spring member 50 can move smoothly without unnecessary interference, and the movement of the operation lever 60 such as raising and lowering becomes smooth.

When the operating lever 60 is rotated to bring the binding member 70 into a hold state (locked state) in which the binding object X is pressed and to an open state (unlocked state) away from the binding object X, that is, to open and close In addition, the spring first end portion 56 of the spring member 50 rotates, but the winding portion 52 contracts or loosens accordingly. Therefore, the inner diameter of the winding part 52 is configured so that a gap is provided slightly between the outer diameter of the shaft 58. The winding portion 52 is wound on the outer peripheral surface of the shaft 58.
That is, the winding portion 52 extends from the spring second end portion 54 side toward the spring first end portion 56 side so as to obliquely intersect the longitudinal direction of the operation lever 60, and the spring first end of the spring member 50. The portion 56 side is fixed to the substrate 22 at a position farther from the spring second end portion 54 side.
When no external force acts on the spring member 50, the spring second end portion 54 is formed so as to push up the free end of the operation lever 60 with the shaft 58 as a pivot portion, and the spring first end portion 56 forms the binding member 70 on the substrate. It is formed so as to approach the surface of 22.
Since the spring second end portion 54 of the spring member 50 is fixed to the operation lever 60 substantially parallel to the longitudinal direction of the operation lever 60, the spring member 50 is substantially parallel to the bearing plate 24 when the operation lever 60 is pushed down toward the lying down position. The protrusion 100 constituting the lock mechanism can be engaged with the engagement body 120 by being pushed down in a simple direction, that is, in the vertical direction.
