  Each binding member 7 includes, for example, a first binding member 21 and a second binding member 22 that are formed of synthetic resin or the like and make a pair.

  Each of the first binding member 21 and the second binding member 22 is provided with a rectangular plate-shaped frame portion 23 having flexibility. One end of the frame portion 23 is connected to the front wall portion 12, and a rectangular plate-like insertion portion 24 is integrally connected to the other end and substantially perpendicular to the frame portion 23. The insertion portion 24 can be inserted into the through holes 17a and 17b and the binding hole of the object to be bound.

  A rectangular plate-like operation member 25 is integrally connected to each second binding member 22 on the outer surface side of each second binding member 22 and connected to the frame portion 23 and the insertion portion 24. Thus, the two binding members 7 are connected.

  Further, an operation portion 26 formed in an arc shape is provided at a portion that is substantially the center portion of the end portion in the width direction of the operation member 25 and faces the notch portion 19 in the lying state.

  As shown in FIG. 4, each frame portion 23 of the first binding member 21 and the second binding member 22 has one end opposite to the insertion portion 24 at the front wall of the binding tool body 6 via the first hinge portion 27. The unit 12 is integrally connected. Each of these frame portions 23 can be rotated with respect to the binding tool body 6 with the first hinge portion 27 as a base point. Further, an insertion part 24 is connected to the other end of each frame part 23. Further, the insertion portion 24 of the first binding member 21 and the insertion portion 24 of the second binding member 22 that form a pair are such that the distal end portion of each insertion portion 24 opposite to the end portion on the frame portion 23 side is the second hinge. They are integrally connected via the part 28. Each insertion portion 24 is rotatable about the second hinge portion 28 so that the base end portions on the side of the frame portion 23 come in contact with each other, and the through-hole 17a is in a state where the insertion portions 24 are substantially parallel. , 17b can be inserted. Further, the operation member 25 is integrally connected to the second binding member 22 via the third hinge portion 29.

  The binding member 7 is inclined with respect to the front wall portion 12 with the insertion portion 24 side of each frame portion 23 of the first binding member 21 and the second binding member 22 as shown in FIG. In addition, the insertion portion 24 of the first binding member 21 and the insertion portion 24 of the second binding member 22 are substantially V-shaped, and the standing state where each insertion portion 24 is not inserted into the through holes 17a and 17b, Each frame part 23 as shown in FIG. 3 is substantially parallel to the front wall part 12 and the back wall part 13, and the insertion part 24 of the first binding member 21 and the insertion part 24 of the second binding member 22 are substantially the same. It is possible to change between a parallel state and a lying state inserted through the through holes 17a and 17b.

  Each insertion portion 24 of the first binding member 21 and the second binding member 22 has the insertion portion 24 in a lying state in the vicinity of the distal end portion on the opposite side of each frame portion 23 with the engaging portion 30 formed in a concave shape. Are provided on the three outer surfaces other than the surfaces facing each other.

  Further, the front wall 12 side of the periphery of the through-hole 17b in the back wall 13 is formed in a convex shape with respect to the back wall 13 side of the periphery of the through-hole 17b and can be engaged with the engagement portion 30. An engaged portion 31 is formed. The engaging portion 30 and the engaged portion 31 are not normally engaged when the insertion portion 24 is only inserted through the through-hole 17b. However, for example, an external force such as the weight of the object to be bound is applied to the insertion portion 24. It engages when the engaging part 30 moves toward the engaged part 31 side.

  Next, the operation of the first embodiment will be described.

  When binding the object to be bound into the file 1, first, the front cover 2 and the back cover 4 are spread from the state in which the file body 5 is bent at the folding lines 11a and 11b.

  In the binding tool 8 in which the binding member 7 is in the lying state, the finger is hooked on the operation portion 26 of the operation member 25, and the operation member 25 is lifted away from the front wall portion 12 to bring the binding member 7 into an upright state.

  The side edge of the binding object on the binding hole side is inserted toward the back wall 14 from the opening 16 of the binding tool body 6. At this time, both ends of the side edge portion of the object to be bound are aligned with the end wall portions 15a and 15b, and the object to be bound is inserted along the end wall portions 15a and 15b.

  In a state where the side edge portion of the binding object on the binding hole side is inserted into the binding tool body 6, the operation member 25 is pushed down to the front wall portion 12 side to bring the binding member 7 into a lying state. When the binding member 7 is in a lying state, as shown in FIG. 5, the insertion portion 24 is inserted through the through hole 17a, the binding hole of the object to be bound, and the through hole 17b, and the object to be bound is bound. Keep state.

  Further, when taking out the object to be bound from the file 1, a finger is hooked on the operation portion 26 of the operation member 25, and the operation member 25 is lifted away from the front wall portion 12, and the binding member 7 is raised. To do. By bringing the binding member 7 upright, the state in which the insertion portion 24 is inserted through the through hole 17a, the binding hole of the object to be bound, and the through hole 17b is released.

  The to-be-sewn object whose insertion of the binding hole by the insertion part 24 has been released is in a state where it can be taken out freely, so that the desired to-be-sewn object is taken out.

  And in such a file 1, each frame part 23 connected to the front wall part 12 via the 1st hinge part 27 has flexibility, On the other hand, the insertion part 24 connected to each frame part 23 Is significantly less flexible than the frame portion 23, and the insertion portion 24 on the first binding member 21 side and the insertion portion 24 on the second binding member 22 side are connected via the second hinge portion 28. Thus, when the binding member 7 is brought into a state between the standing state and the lying state by an external force, the frame portion 23 bends.

  That is, when it is assumed that the insertion portion 24 on the first binding member 21 side and the insertion portion 24 on the second binding member 22 side are not connected, as shown in FIG. The two-binding member 22 is indicated by an alternate long and two short dashes line in which the distal end portion of the insertion portion 24 is centered on the first hinge portion 27 and the radius is a line segment connecting the first hinge portion 27 and the second hinge portion 28. It can move along a circle. However, the insertion part 24 on the first binding member 21 side and the insertion part 24 on the second binding member 22 side are connected via the second hinge part 28, as shown in FIG. When the first binding member 21 and the second binding member 22 are respectively in the standing state and the lying state, the insertion portion 24 is inhibited from moving along the circle indicated by the two-dot chain line. And if the 1st binding member 21 and the 2nd binding member 22 receive the external force which is going to move between a standing state and a lying state, respectively, the 1st binding member 21 will be between a standing state and a lying state. It is compulsory that the tip part of the insertion part 24 on the side and the tip part of the insertion part 24 on the second binding member 22 side draw a trajectory deviating from the circle indicated by their respective two-dot chain lines. Therefore, since stress concentrates on each flexible frame portion 23, the frame portion 23 bends.

  The bent frame portion 23 has an action of returning from the bent state to the unbent state. Therefore, the binding member 7 is easily changed between the standing state and the lying state between the standing state and the lying state, due to the bending of the frame portion 23, either in the standing state or the lying state where the frame portion 23 is not bent. Since the state is easily switched, the object to be bound can be easily attached and detached.

  Further, the binding member 7 is more stable in the standing state or the lying state in which the frame portion 23 is not bent than in the state in which the frame portion 23 between the standing state and the lying state is bent, so that no external force acts. In the state, it is easy to hold the binding member 7 in the standing state or the lying state. Therefore, it is possible to maintain a state in which the binding object 7 is in the lying state and the object to be bound is bound.

  Further, the first hinge portion 27 is a thin hinge integrally formed with the front wall portion 12 and the frame portion 23, and the second hinge portion 28 is the insertion portion 24 of the first binding member 21 and the second binding member 22. By making the thin hinge integrally formed with the insertion portion 24 and the third hinge portion 29 being a thin hinge integrally formed with the operation member 25 and the frame portion 23, the entire binding tool 8 is made of, for example, synthetic resin. Since it can form with the same raw material, the binding tool 8 can be manufactured easily.

  By providing a folding line 11c on the back cover 4 and making it easy to bend the back cover 4 outward at the folding line 11c, the object to be bound is bound into the binding tool body 6 joined to the back cover 4. In this state, since one side portion in which a plurality of binding holes of the object to be bound is formed is bent with the back wall portion 13 as a base point, it is easy to view the object to be bound.

  Since the two binding members 7 are respectively connected to the operation member 25, the two binding members 7 can be set in the standing state and the lying state only by pulling up or pushing the operation member 25 with respect to the binding tool body 6 with one touch. Since the switching can be performed in conjunction with each other, the operability can be improved, and the object to be bound can be attached and detached more easily.

  Further, by providing the operation member 26 on the operation member 25 and providing the notch 19 on the front wall portion 12, the user can easily hook the finger on the operation portion 26, and when the binding tool is raised from the lying down state, Since the operation member 25 can be easily operated, the binding member 7 can be easily switched from the lying state to the standing state.

  The binding tool body 6 includes end wall portions 15a connected to the front wall portion 12, the back wall portion 13 and the back wall portion 14 at both longitudinal ends of the front wall portion 12, the back wall portion 13 and the back wall portion 14, respectively. , 15b, when inserting the object to be bound into the binding tool body 6, by aligning both ends of the side edge on the binding hole side of the object to be bound with the end wall parts 15a, 15b, Since the binding hole of the object to be bound can be adjusted to a position where it can be inserted by the insertion part 24, the position of the object to be bound is hardly displaced and can be bound smoothly.

  Further, even if the file main body 5 is in a state where the end wall portions 15a and 15b face the vertical direction in a state where the binding hole of the object to be bound is inserted by the insertion portion 24, the end wall portions 15a and 15b can The insert is difficult to move in the vertical direction, and it is possible to prevent the binding hole of the binding object from being enlarged or the binding tool 8 from being damaged due to the movement of the binding object.

  In the normal state in which the binding member 7 is in the lying down state, the insertion portion 24 only passes through the through holes 17a and 17b as shown in FIG.

  Here, as shown in FIG. 7A, the file 1 is tilted so that the back wall portion 14 is positioned on the upper side, etc. When the weight acts in the direction from the back wall portion 14 to the opening portion 16, the engaging portion 30 located on the surface of the insertion portion 24 on the opening portion 16 side by the weight of the object to be bound is the peripheral edge of the through hole 17 b. The engaged portion 31 is engaged.

  Further, as shown in FIG. 7B, the weight of the object to be bound indicated by a two-dot chain line bound to the file 1 in a state where the file 1 is tilted so that the end wall portion 15a is located on the upper side. However, when acting in the direction from the first binding member 21 to the second binding member 22, that is, from the end wall portion 15a to the end wall portion 15b, the insertion of the second binding member 22 by the weight of the object to be bound is performed. The engaging portion 30 on the end wall portion 15b side of the portion 24 engages with the engaged portion 31 on the peripheral edge of the through hole 17b.

  Further, as shown in FIG. 7C, the weight of the object to be bound indicated by a two-dot chain line bound to the file 1 in a state where the file 1 is inclined so that the end wall portion 15b is located on the upper side. However, when acting in the direction from the second binding member 22 to the first binding member 21, that is, from the end wall portion 15b to the end wall portion 15a, the insertion of the first binding member 21 by the weight of the object to be bound is performed. The engaging portion 30 on the end wall portion 15a side of the portion 24 engages with the engaged portion 31 on the periphery of the through hole 17b.

  As described above, the engagement portion 30 is formed in the vicinity of the distal end portion of the insertion portion 24 opposite to the frame portion 23, so that the weight of the object to be inserted is inserted in the state where the insertion portion 24 is inserted through the through hole 17b. When the insertion part 24 is moved by the above or the like, the engagement part 30 can be engaged with the peripheral edge of the through hole 17b, and the insertion state of the insertion part 24 can be maintained. Therefore, it is possible to prevent the insertion state of the insertion portion 24 from being released due to the weight of the object to be bound or other external force. Further, it is possible to prevent the binding tool body 6 and the binding member 7 from being damaged due to the release of the insertion state.

  Furthermore, by forming the engaged portion 31 on the front wall portion 12 side of the periphery of the through hole 17b, the engaging portion 30 can be more firmly engaged, so that the holding force in the inserted state can be improved, and the inserted state can be improved. It can be made harder to release.

  Further, the insertion portion 24 is not limited to a rectangular plate shape, and can be appropriately formed in a rod shape or the like as long as it can be inserted through the through holes 17a and 17b and the binding hole of the object to be bound.

  The first hinge portion 27 is formed integrally with the frame portion 23 and the front wall portion 12 with synthetic resin, and the second hinge portion 28 is formed with the insertion portion 24 of the first binding member 21 and the second binding member 22 with synthetic resin. The configuration formed integrally with the insertion portion 24 is preferable because the entire binding tool 8 can be integrally formed of the same material and can be easily manufactured, but is not limited to such a configuration, and the first hinge portion As the 27 and the second hinge portion 28, for example, another member such as a hinge may be attached, and the frame portion 23 and the insertion portion 24 may be rotated more accurately.

  The insertion portion 24 is not limited to the configuration in which the concave engagement portion 30 is provided in the vicinity of the distal end portion on the side opposite to the frame portion 23, and may be configured without the engagement portion 30. Moreover, when providing the engaging part 30, it is not limited to the structure formed in 3 surfaces which are the outer surfaces of the insertion part 24 which becomes substantially parallel in a lying state, It is either 3 surfaces which are outer surfaces A configuration in which the engaging portion 30 is formed only on one surface or two surfaces may be employed.

  Furthermore, it is preferable to form the engaged portion 31 at the periphery of the through hole 17b, since the engaging portion 30 can be easily engaged with the periphery of the through hole 17b. A configuration in which the joint portion 31 is not formed may be employed.

  Next, a second embodiment will be described with reference to FIGS. 8 (a) and 8 (b). In addition, about the structure same as said embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  As shown in FIGS. 8A and 8B, the frame portions 23 of the first binding member 21 and the second binding member 22 are formed by two rectangular plate-like frame bodies 33a and 33b.

  One end of the frame body 33a is connected to the front wall portion 12 via the first hinge portion 27, and the insertion portion 24 is connected to the other end.

  In addition, one end of the frame body 33b is connected to the front wall portion 12 via the fourth hinge portion 32, and the other end is connected to the frame body 33a via the fifth hinge portion 34. The fifth hinge portion 34 can be pivoted with respect to the frame body 33a. Furthermore, a sixth hinge portion 35 is provided on the frame body 33b. With this configuration, when the first binding member 21 and the second binding member 22 receive an external force that attempts to change the binding member 7 from the standing state to the lying state, first, the frame body 33a is separated from the frame body 33a. The stress concentrates and bends between the end and the fifth hinge portion 34. When receiving a stronger external force, the stress concentrated between the other end of the frame body 33a and the fifth hinge part 34 is caused between the first hinge part 27 and the fifth hinge part 34 in the frame body 33a and the frame. When it is transmitted to the body 33b and the binding member 7 is put in a lying state, the frame body 33b is bent and folded in the direction toward the frame body 33a by the sixth hinge portion 35.

  Thus, when the frame portion 23 is configured by the two frame bodies 33a and 33b, a larger external force is required when the binding member 7 is changed from the standing state to the lying state. That is, when the binding member 7 is changed from the lying state to the standing state, a larger external force is required. Therefore, since the standing state and the lying state can be more stably maintained, the object to be bound can be bound more reliably.

  In the second embodiment, the frame portion 23 is formed by the two frame bodies 33a and 33b. However, the number of the frame bodies 33 is not limited to two and can be set as appropriate. Furthermore, the number of frame bodies 33 of the frame portion 23 in the first binding member 21 and the number of frame bodies 33 of the frame portion 23 in the second binding member 22 may be different.

  Further, in the configuration in which the frame portion 23 is formed by the plurality of frame bodies 33, it is only necessary that the end of at least one frame body 33 among the plurality of frame bodies 33 is connected to the front wall portion 12. The insertion part 24 should just be connected to either of the bodies 33. FIG.
