Description

  The present invention relates to a binding tool, and more particularly to, for example, a binding tool having a bar-like portion for binding a document to a file.

  FIG. 25 is an illustrative view showing one example of a conventional binding device as a background of the present invention. The binding tool 1 includes a bottom plate 2 and a fixed side plate 3 orthogonal to the bottom plate 2 on one side in the width direction of the bottom plate 2. Further, on the other side in the width direction of the bottom plate 2, a rotating side plate 4 that can rotate with respect to the bottom plate 2 is formed. Two binding tubes 5 are formed so as to protrude perpendicularly from the surface of the rotating side plate 4. A comb plate 6 having a binding rod to be inserted into the tube 5 is attached to the distal end side of the tube 5. A protrusion 7 is formed on the comb plate 6 on the side opposite to the protruding surface of the binding hook. As shown in FIG. 26, the rotation side plate 8 that is biased toward the fixed side plate 3 by a spring is attached to the fixed side plate 3. A central bent portion 8 a is formed at the center in the width direction of the rotating accessory plate 8 and is exposed from the fixed side plate 4. In addition, two holes 9 are formed on both sides of the central bent portion 8 in the rotating attachment plate 8, and these holes 9 are exposed from the fixed side plate 3.

  The binding tool 1 is attached to a back cover of a file, and a document is held in the binding tube 5. When the document is held in the binding tube 5, the comb plate 6 is attached to the binding tube 5, and the rotation side plate 4 is rotated by closing the cover. Thereby, the end portion of the comb plate 6 is fitted and fixed to the central bent portion 8 a of the rotation attachment plate 8. Further, the protrusion 7 formed on the comb plate 6 fits into the hole 9 of the rotating plate 8 so that the comb plate 6 is not easily fixed by the central bent portion 8a. Then, when removing the document, by rotating the rotation plate 8, the central bent portion 8 a is released from the end of the comb plate 6, the rotation side plate 4 is rotated, and the comb plate 6 is moved to the tube 5. (See Patent Document 1).

Japanese Utility Model Publication 2-35503

In such a binding tool, when a large amount of documents are bound in the binding tube, a force is applied to the binding tube depending on the weight of the document, and a force is applied in a direction in which the comb plate is deeply fitted into the central bending portion. For this reason, even if it is attempted to open the central bent portion from the end portion of the comb plate by rotating the rotary accessory plate, it is difficult to easily disengage the central bent portion from the comb plate.
Further, from the viewpoint of resource saving, it is desired to use as little material as possible. However, since the interval between the tubes is determined by the standard, it is difficult to shorten the length of the bottom plate and the side wall. Therefore, it is conceivable to shorten the length of the rotating attachment plate, leave only the vicinity of the portion where the central bent portion is formed, and omit both side portions. However, in that case, the hole formed in the rotating accessory plate disappears, and the protrusion of the comb plate cannot be supported. Further, the protrusions of the comb plate are supported by the holes of the rotating plate so that the central bent portion is not accidentally detached from the end portion of the comb plate, and counteracts the force applied in the longitudinal direction of the fixed side plate. It is not a thing. Therefore, if a file with a binding tool attached is dropped while the document is bound, a force is applied in the longitudinal direction of the fixed side plate, and the binding tool may be damaged.

SUMMARY OF THE INVENTION Therefore, a main object of the present invention is to provide a binding device having a configuration that does not make it difficult to remove a document even when a large amount of documents are bound.
Another object of the present invention is to provide a binding device that can cope with resource saving and is not easily damaged even if a file is dropped in a state where documents are bound.

The present invention has a base material attached to a cover of a file, a rod-shaped portion for binding documents, and two side wall members for fixing both end sides of the rod-shaped portion, and one side wall member is one of the width directions of the substrate. A binding member that is pivotally attached to the side, and a latch that fits into an engagement portion at the end of the other side wall member of the binding member in order to fix the binding member to the base material on the other side in the width direction of the base material. It has a claw and a regulating portion for regulating the depth at which the engagement of the other side wall member is fitted inside the locking claw in the vicinity of the locking claw, and rotates to the other side in the width direction of the base material It is a binding tool including a locking member that can be attached.
The document is bound to the rod-shaped portion of the binding member that is rotatably attached to the base material, and the binding member is fixed to the base material by the locking member. At this time, the engaging portion of the binding member is engaged by the engaging claw of the engaging member, but the depth of the side wall member fitted inside the engaging claw is restricted by the restricting portion. The engaging portion of the side wall member does not enter the inside of the locking claw.

In such a binding tool, the engaging claw that fits into the engaging portion at the end of the one side wall member of the binding member, and the engaging portion of the one side wall member in the vicinity of the engaging claw are inside the engaging claw. A restricting portion for restricting the fitting depth, and including another locking member rotatably attached to one side in the width direction of the base material. One side wall member may be rotatably attached to one side in the width direction of the base material by fitting a locking claw of the locking member.
One side wall member of the binding member is pivotally attached to one side in the width direction of the base material, but may be attached to the base material by another locking member in the same manner as the other side wall member. In this case, the locking member can be released on both sides of the binding member, and the document can be taken in and out from either of the binding members. Even in this case, since the depth of the side wall member fitted inside the locking claw is regulated by the regulating portion by forming the regulating portion on both the locking members, the engagement of the side wall member to a certain depth or more is possible. The joint does not enter the inside of the locking claw.

Further, in the binding device in which the other side wall member of the binding member is attached to the base material by the locking member, the locking member is provided in the vicinity of the central portion in the longitudinal direction of the other side wall member and the other side wall member is engaged. A pinching portion that protrudes at an interval in the longitudinal direction of the other side wall member so as to sandwich the locking member when the portion is fitted inside the locking claw may be formed.
Further, in the binding device in which both side wall members of the binding member are attached to the base member by the locking member, the locking member is provided in the vicinity of the center portion in the longitudinal direction of the other side wall member, and the other side wall member is engaged. When the portion is fitted inside the locking claw, a holding portion that protrudes at an interval in the longitudinal direction of the other side wall member is formed so as to sandwich the locking member. One side wall member is provided in the vicinity of the central portion in the longitudinal direction, and when the engaging portion of one side wall member is fitted inside the locking claw of the other locking member, the other locking member is sandwiched between them. A sandwiching portion that protrudes at an interval in the longitudinal direction may be formed.
The locking member is formed in the vicinity of the central portion in the longitudinal direction of the side wall member, and when the engaging portion of the side wall member is fitted inside the locking claw, the locking member is sandwiched between the locking members in the longitudinal direction. Since the sandwiching portions projecting apart are formed, even if a force is applied to the rod-shaped portion in the longitudinal direction of the base material, the positional relationship between the side wall member and the locking member does not change.

In addition, the present invention has a base material attached to the cover of a file, a rod-shaped portion for binding documents, and two side wall members for fixing both end sides of the rod-shaped portion, and one side wall member is the width direction of the substrate. A binding member rotatably attached to one side of the binding member, and a fitting member fitted into an engagement portion at the end of the other side wall member of the binding member in order to fix the binding member to the base material on the other side in the width direction of the base material. A locking member having a pawl, provided in the vicinity of the central portion in the longitudinal direction of the other side wall member, and rotatably attached to the other side in the width direction of the base material, and an engaging portion of the other side wall member Is a binding tool including a projecting sandwiching portion that is formed at an interval in the longitudinal direction of the other side wall member so as to sandwich the locking member when fitted inside the locking claw.
The document is bound to the rod-shaped portion of the binding member that is rotatably attached to the base material, and the binding member is fixed to the base material by the locking member. Here, the locking member is formed in the vicinity of the central portion in the longitudinal direction of the side wall member, and when the engaging portion of the side wall member is fitted inside the locking claw, the locking member is sandwiched between the longitudinal direction of the side wall member. Therefore, even if a force is applied to the rod-shaped portion in the longitudinal direction of the base material, the positional relationship between the side wall member and the locking member does not change.

In such a binding tool, another latch that has a latching claw that fits into the engagement portion at the end of one side wall member of the binding member and is rotatably attached to one side in the width direction of the base material Including a member, and when the engaging portion of one side wall member is fitted inside the locking claw of another locking member, the other locking member is sandwiched and spaced apart in the longitudinal direction of one side wall member A projecting nipping portion may be included.
One side wall member of the binding member is pivotally attached to one side in the width direction of the base material, but may be attached to the base material by another locking member in the same manner as the other side wall member. In this case, the locking member can be released on both sides of the binding member, and the document can be taken in and out from either of the binding members. Even in this case, by forming the clamping portions in both the locking members, even if a force is applied to the rod-shaped portion in the longitudinal direction of the base material, the positional relationship between the side wall member and the locking member does not change. Can be.

Further, when the binding member is locked to the base material by the locking member, the one protruding piece protruding from the base material and the other protruding piece protruding from the side wall member are in contact with each other in the direction orthogonal to the rod-shaped portion. It is preferable that one projecting piece is sandwiched between two other projecting pieces, or the other projecting piece is disposed between two projecting pieces.
One protruding piece protruding from the base material and the other protruding piece protruding from the side wall member intersect each other so that one protruding piece is sandwiched between two other protruding pieces, or the other protruding piece Is sandwiched between two protruding pieces, the positional relationship between the base material and the binding member can be kept unchanged.

According to the present invention, since the restricting portion is formed, the engaging portion of the side wall member does not enter the inside of the locking claw up to a certain depth, so that a large amount of documents are bound and force is applied to the binding member. Even if it adds, when the latching claw is removed from the engaging portion of the side wall member, the amount of the latching claw that gets over the engaging portion does not increase. Therefore, even when a large amount of documents are bound, it is not difficult to release the locking claw from the engaging portion of the side wall member.
Further, by forming the locking member in the vicinity of the central portion in the longitudinal direction of the side wall member, the length of the locking member can be shortened, and the demand for resource saving can be met. In this case, by forming a holding portion that protrudes at an interval in the longitudinal direction of the side wall member so as to hold the locking member when the engaging portion of the other side wall member is fitted inside the locking claw, Even if force is applied in the longitudinal direction of the tool, the positional relationship between the side wall member and the locking member does not change. Therefore, even if the file is dropped in a state where the document is bound to the binding tool, the binding tool can be prevented from being damaged.
Furthermore, the one protruding piece protruding from the base material and the other protruding piece protruding from the side wall member intersect each other so that one protruding piece is sandwiched between two other protruding pieces, or the other protruding piece When the protruding piece is sandwiched between the two protruding pieces, the positional relationship between the base material and the binding member does not change. Therefore, even if the file is dropped in a state where the document is bound to the binding tool, the binding tool can be prevented from being damaged.

The bearing portion 94b is disposed between the bearing portion 26b disposed with the center portion in the longitudinal direction of the base material 20 and the protruding plate 26a adjacent thereto. In this state, the shaft 28 is inserted into the bearing portion 26b of the base member 20 and the passage 96 of the bearing portions 94a and 94b of the locking member 90, and one of the bearing portions 26b of the base member 20 is crushed to fix the shaft 28. Accordingly, the locking member 90 is rotatably attached to the base member 20 so that the base members 92 of the first and second locking members 90 are parallel to each other.

  The binding member 40 is fixed to the base material 20 by the first and second locking members 90. The binding member 40 is configured by inserting and combining the pins 62 of the pin base 42 into the pipes 82 of the pipe base 64. When the pin base 42 and the pipe base 64 are combined, the arc-shaped portion 52 and the second inclined portion 54 formed on the pin base 42 straddle one shaft 28 and are formed on the pipe base 64. The lengths of the pin 62 and the pipe 82 are set so that the arcuate portion 74 and the second inclined portion 76 straddle the other shaft 28.

  When the binding member 40 is placed on the shaft 28 of the base material 20, the arc-shaped portion 52 of the pin base 42 and the arc-shaped portion 74 of the pipe base 64 are arranged at positions corresponding to the protruding plate 26 a of the base material 20. Is done. In addition, the edge of the second inclined portion 54 formed on both sides of the arc-shaped portion 52 of the pin base 42 is between the protruding plate 26a of the base member 20 and the bearing portion 26b, and the edge of the protruding plate 26a. Arranged so that they touch and intersect. Similarly, the edge of the second inclined portion 76 formed on both sides of the arc-shaped portion 74 of the pipe base 64 is the edge of the protruding portion 26a between the protruding plate 26a of the base member 20 and the bearing portion 26b. It is arranged to intersect with and intersect.

  Thus, in a state where the pin base 42 and the pipe base 64 are placed on both the shafts 28, the first and second locking members 90 are moved from the outside of the binding member 40 toward the pin base 42 and the pipe base 64. 24, the engaging claw 106 is engaged with the engaging portion 48 formed on the side wall member 44 of the pin base 42 and the engaging portion 70 formed on the side wall member 66 of the pipe base 64, as shown in FIG. Combined. Thereby, the side wall member 44 of the pin base 42 is fixed to the base material 20 by the first locking member 90, and the side wall member 66 of the pipe base 64 is fixed to the base material 20 by the second locking member 90. Therefore, the binding member 40 in which the pin 62 and the pipe 82 are combined and integrated is fixed to the base member 20 by the first and second locking members 90 disposed on both sides of the binding member 40. At this time, the pinching portion 60 formed on the pin base 42 and the pinching portion 80 formed on the pipe base 64 on both sides in the longitudinal direction of the first and second locking members 90, that is, on both side surfaces of the rib 104. The end is abutted. Further, the flat plate portion of the locking member 90 is disposed along the flat plate portions of the side wall members 44 and 66.

  In order to bind a document to the binding tool 10, for example, the first locking member 90 engaged with the pin base 42 is removed from the engaging portion 48. Then, by rotating and tilting the first locking member 90, the tongue piece 102 of the first locking member 90 hits the first inclined portion 50 of the pin base 42 and the pin base 42 is lifted. At this time, since the pipe base 64 is rotatably attached to the base material 20 by the second locking member 90, the binding member 40 can be rotated. Therefore, the binding member 40 is rotated until the rod-like portion 84 is standing, and the pin base 42 is removed from the binding member 40.

  When the pin base 42 is removed, the pipe 82 of the pipe base 64 protrudes, and the pipe 82 is passed through a hole formed in the document to hold the document. When the document is passed through the pipe 82, the pin 62 of the pin base 42 is inserted into the pipe 82, and the binding member 40 is formed. Accordingly, the document is sandwiched between the side wall member 44 of the pin base 42 and the side wall member 66 of the pipe base 64.

  The binding member 40 is rotated while the document is held, and the pin base 42 is brought close to the base material 20. Accordingly, the first inclined portion 50 formed on the pin base 42 hits the tongue piece 102 of the first locking member 90, and the first locking member 90 rises. Then, by engaging the locking claw 106 of the first locking member 90 with the engaging portion 48 of the pin base 42, the binding member 40 is fixed to the base material 20, and the document is bound to the cover 12. When removing the bound document, the locking claw 106 of the first locking member 90 engaged with the engaging portion 48 of the pin base 42 may be removed, and the pin base 42 may be removed from the binding member 40.

  The second locking member 90 on the pipe base 64 side is removed from the engaging portion 70 of the pipe base 64, and the binding member 40 is rotated in a state where the pin base 42 is attached to the base member 20, and the binding member 40 is rotated. The pipe base 64 may be removed from the pin 62 and the document may be held on the pin 62.

  In the binding device 10, the engaging claws 106 of the first and second engaging members 90 get over the engaging portions 48 of the pin base 42 and the engaging portions 70 of the pipe base 64, thereby engaging portions 48, 70 is engaged with the locking claw 106 or is disengaged from the locking claw 106. For this purpose, the locking claw 106 needs to be displaced. However, since the through hole 108 is formed in the base member 92 at the portion where the locking claw 106 is formed, the locking claw 106 can be displaced.

  When the engaging portion 48 of the pin base 42 and the engaging portion 70 of the pipe base 64 are engaged with the first and second locking members 90, the engaging portions 48 and 70 are engaged with the engaging claws 106. It is locked by the stop inner wall 106a. Here, when a large amount of documents are held on the rod-shaped portion 84, a force toward the deep portion inside the locking claw 106 acts on the engaging portions 48 and 70 due to the weight of the documents. However, in this binding device 10, as shown in FIG. 24, restricting portions 116 are formed on both sides of the locking claw 106, and the restricting portion bottom surface 116 a is inside the locking claw 106 and the engaging portions 48, 70. Regulates the depth of penetration. Therefore, the engaging portions 48 and 70 do not enter the inside of the locking claw 106 deeper than the position where the restricting portion bottom surface 116a is formed. As a result, when the locking member 90 is removed from the engaging portions 48 and 70, the amount of the engaging claw 106 over the engaging portions 48 and 70 does not increase beyond a certain level, and the first and second locking members It is not difficult to remove 90 from the pin base 42 and the pipe base 64.

  Further, in this binding device 10, the first and second locking members 90 are not formed along the entire surface of the side wall member 44 of the pin base 42 and the side wall member 66 of the pipe base 64, and the engaging portions 48, First and second locking members 90 are formed at positions corresponding to 70. That is, the first and second locking members 90 are not formed on both end sides in the longitudinal direction of the side wall members 44 and 66, and the amount of material used for the locking members 90 can be suppressed. Thus, since the first and second locking members 90 are formed only in necessary portions, it is possible to meet the demand for resource saving.

  Further, when the binding member 40 is locked by the first and second locking members 90, the pinching portion 60 of the pin base 42 and the pipe base 64 are provided on both sides in the longitudinal direction of the first and second locking members 90. Since the first and second locking members 90 are clamped by the clamping unit 60 and the clamping unit 80, the first and second locking members 90 are held by the clamping units 60 and 80. Fixed at a fixed position. Therefore, when a file is dropped on the floor in a state where a document is bound in the binding tool 10, force is applied to the rod-shaped portion 84, and the pin base 42 and the pipe base 64, the first and second locking members 90, However, the positional relationship between the pin base 42 and the pipe base 64 and the first and second locking members 90 does not change. Therefore, damage to the locking claws 106 and the like of the first and second locking members 90 can be prevented. Thus, by forming the clamping part 60 in the pin base 42 and forming the clamping part 80 in the pipe base 64, it is possible to prevent the binding device 10 from being damaged by an external force.

  Further, on the outside of the two protruding plates 26a of the base member 20, the second inclined portion 54 formed on the side wall member 44 of the pin base 42 intersects with the protruding plate 26a. Similarly, the second inclined portion 76 formed on the side wall member 66 of the pipe base 64 intersects with the protruding plate 26a outside the other protruding plate 26a of the base member 20. Thus, in the relationship between the base material 22 and the pin base 42, the protruding plate 26a that is one protruding piece and the second inclined portion 54 that is the other protruding piece intersect each other so as to be in contact with each other. The inclined portion 54 is arranged so as to sandwich the protruding plate 26a. Further, in the relationship between the base material 22 and the pipe base 64, the protruding plate 26a, which is one protruding piece, intersects with the second inclined portion 76 so as to contact each other, and the second inclined portion 76 connects the protruding plate 26a. It is arranged to sandwich. Therefore, even if the file is dropped on the floor and a force is applied between the base material 20 and the binding member 40, the positional relationship between the base material 20 and the binding member 40 can be prevented from changing. Therefore, the binding tool 10 can be prevented from being damaged by an external force even between the base member 20 and the binding member 40.

  In such a relationship between the base material 20 and the binding member 40, the positional relationship between the protruding plate 26a of the base material 20 and the second inclined portion 54 of the pin base 42 may be reversed. That is, the second inclined portion 54 is formed inside, the protruding plate 26a is formed outside the second inclined portion 54, and the two protruding plates 26a sandwich the second inclined portion 54. May be. Similarly, the positional relationship between the protruding plate 26a of the base member 20 and the second inclined portion 76 of the pipe base 64 can be reversed.

  The locking member 90 is formed on both the pin base 42 side and the pipe base 64 side, but may be formed only on one of them. In this case, on the side where the locking member 90 is not provided, the pin base 42 or the pipe base 64 is directly attached to the shaft 28 of the base member 20 so as to be rotatable.
