Description

  The present invention has a pipe portion and an insertion rod that can be fitted to the pipe portion, and for example, a so-called pipe type that holds and holds a binding object provided with an engagement hole such as a document or a storage holder. It relates to a binding tool.

  Conventionally, as this type of binding tool, a bottom plate as a base member in which inclined portions as standing portions are provided upright on both side edges in the longitudinal direction, and the upper edge of each inclined portion are rotatably attached. A side plate as a first side member and a side plate as a second side member, and a binding comb plate as a first binding member and a second binding member as first binding members arranged to face the inner side surfaces of these side plates, respectively. A binding comb plate, and at least one of the binding comb plates is detachable from the side plate, and one of the binding comb plates has a cylindrical pipe portion. There is known a configuration in which an outer insertion binding rod is provided, and on the other side, an insertion binding rod is provided as a rod-shaped insertion rod that can be fitted to the pipe portion (see, for example, Patent Document 1). ).

  In the binding tool having such a configuration, each of the side plates can be rotated between an open state in which the free end is located outside and an upright state in which the free end is located on the side opposite to the bottom plate from the base end. When attaching and detaching the object to be bound, one of the binding comb plates is removed from the side plate, the other side plate is opened, and the fitting between the outer insertion staple and the insertion staple is released. Then, the object to be bound is removed.

  Further, in this type of binding tool, the second binding member is detachably attached to the second side member, and the first binding member is integrally provided on the first side member, so-called one-side opening. There is a formula. In such a single-opening configuration, the first side member is attached with a biasing means that biases the first side member so as to rotate outward, and the second binding member is simply removed from the second side member. The first side member and the first binding member rotate together with the second binding member in a state where the pipe portion and the insertion rod are fitted by the urging force of the urging means, and detachment of the object to be bound is performed. The thing of the structure which can work easily is known.

  Here, when the first side member 3 is rotated to the open state, the pipe portion 72 is inserted into the position corresponding to the connecting portion 17 of the upright portion 12 between the attachment portions 73 of the first side member 3. A rotation restricting member 78 is provided as a fitting holding means for holding the fitting state with the flange 55.

  The rotation regulating member 78 regulates the rotation range of the first side member 3 so that the fitting between the pipe portion 72 and the insertion rod 55 is not released by the rotation of the first side member 3.

  The rotation restricting member 78 has a notch recess 79 that is notched in a concave shape from the base end side of the first side member 3 toward the free end side, and a notched portion of the notch recess 79 is bent. And a regulating piece 80 formed in the above manner.

Is formed.

  In addition, the regulating piece 80 rotates with the rotation of the first side member 3, and as shown in FIG. 6, when the first side member 3 is in the open state, the tip of the regulating piece 80 is connected to the upright portion 12. The outer surface of the part 17 is contacted. By this contact, the rotation of the first side member 3 is restricted, and the first side member 3 is substantially parallel to the bottom portion 11, that is, the angle between the pipe portion 72 and the bottom portion 11 is substantially perpendicular.

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

  When binding the object to be bound to the binding tool 1, first, the engagement hole of the object to be bound is engaged with the pipe part 72, and the insertion rod 55 of the second binding member 6 is engaged with the pipe part 72. To do.

  In a state where the pipe portion 72 and the insertion rod 55 are fitted, the first side member 3 together with the second binding member 6 is rotated with respect to the upright portion 12 to be in an upright state.

  As the first side member 3 rotates, the binding plate portion 52 of the second binding member 6 is disposed between the upper clamping portion 27 and the lower clamping portion 28 of the second side member 5. The lower clamping unit 28 is pushed in on the extension unit 61 side of the binding plate unit 52.

  Specifically, the engaging protrusion 59 of the engaging portion 58 in the binding plate portion 52 is slid along the first engaging piece 36 of the engaged portion 33 in the upper holding portion 27, and the lower holding portion 28. Is pushed in a direction away from the free end of the upper clamping part 27.

  Further, when pushing, the extended convex portion of the binding plate portion 52 is inserted between the two tip pieces 45 of the lower holding portion 28, and the extended hook portion 63 of the binding plate portion 52 is inserted into the lower holding portion 28. It pushes in the state engaged with the receiving part 49.

  By pushing the lower clamping part 28 in this way, the lower clamping part 28 rotates against the urging force of the clamping urging spring 29, and the free end part of the lower clamping part 28 and the upper clamping part 27. Are separated from the free end.

  Due to the rotation of the lower clamping unit 28, the distance between the free end of the upper clamping unit 27 and the free end of the lower clamping unit 28 is separated from the length in the width direction of the binding plate unit 52, and the upper clamping unit 27. When the binding plate portion 52 is disposed between the lower clamping portion 28 and the lower clamping portion 28, the biasing force of the clamping biasing spring 29 causes the free end portion of the upper clamping portion 27 to rotate toward the lower clamping portion 28. Thus, the binding plate 52 is clamped by the upper clamping unit 27 and the lower clamping unit 28.

  In the clamping state, the receiving portion 49 and the extended hook portion 63 are engaged, the locking claw portion 31 and the locking recess portion 56 are engaged, and the engaging portion 58 and the engaged portion 33 are engaged. The engagement restricting portion 35 and the opening 60 of the engaging protrusion 59 are engaged with each other, and the sandwiched state is maintained.

  Thus, when the 1st side member 3 is rotated and the 2nd side member 4 is made into the clamping state, the 1st side member 3 and the 2nd side member 4 will be in an upright state, and a to-be-sewn object is bound. Hold the state.

  When the second side member 4 in the sandwiched state is raised, a part of the lower sandwiched portion 28 is located in the notch 21, and the support portion 22 of the raised portion 12 extends along the outside of the lower sandwiched portion 28. It will be in a state and will contact and support the lower clamping part 28. FIG.

  When removing the object to be bound that has been bound in the binding tool 1, the upper clamping portion 27 of the second side member 4 is moved against the lower clamping portion 28 against the biasing force of the clamping biasing spring 29. Rotate the free end to the outside to release the pinching state and put it into the non-pinching state.

  When the clamping state is released, the first side member 3 is urged by the rotation urging spring 74 and automatically rotates from the standing state to the open state as shown in FIG.

  Here, the rotation range of the first side member 3 is restricted by the rotation restricting member 78. Specifically, when the first side member 3 is rotated to the open state and the angle between the pipe portion 72 and the insertion rod 55 in the fitted state and the bottom portion 11 is substantially perpendicular, the restriction piece 80 is connected to the connection portion. The first side member 3 is brought into an open state by contacting the outer surface of 17 and the rotation is locked.

  In the opened state, the fitting between the pipe portion 72 and the insertion rod 55 is released, the second binding member 6 is removed, and the object to be bound is removed from the pipe portion 72.

  In the binding tool 1, the rotation restricting member 78 is provided as a fitting maintaining means, so that the rotation is applied by the rotation biasing spring 74 in a state where the pipe portion 72 and the insertion rod 55 are fitted. Even if the first side member 3 rotates while being biased, the fitting state between the pipe portion 72 and the insertion rod 55 is difficult to be released.

  That is, by providing the rotation restricting member 78, the rotation range of the first side member 3 is restricted so that the fitting between the pipe portion 72 and the insertion rod 55 is difficult to be released by the rotation. The fitting with the insertion rod 55 can be maintained, and the release of the fitting between the pipe portion 72 and the insertion rod 55 due to the rotation of the first side member 3 can be prevented.

  In the binding tool 1, it is generally assumed that the object to be attached is attached / detached in a state where the file is placed so as to be substantially horizontal. However, the first side member 3 is substantially the same as the bottom 11 in the opened state. By restricting the rotation range to be parallel, the fitting direction of the pipe portion 72 and the insertion rod 55 in the open state becomes the gravitational direction in use, so that the weight of the second binding member 6 is maximized. Therefore, the fitting state between the pipe portion 72 and the insertion rod 55 by rotation can be more reliably maintained.

  Further, until the second binding member 6 stands up and the pipe portion 72 is at a right angle with respect to the bottom portion 11, the rotation speed is low due to the weight of the second binding member 6, etc. The weight of the second binding member 6 and the like is added to the biasing force of the rotation biasing spring 74, the rotational speed is increased, and the second binding member 6 is likely to jump out. Therefore, it is preferable that the maximum pivotable angle of the pipe portion 72 with respect to the bottom portion 11 is substantially a right angle or smaller. In order to easily insert and remove a document or the like, it is preferable to set it to a substantially right angle, preferably a right angle or a slightly smaller angle than the right angle.

  A rotation restriction member 78 is provided around the rotation axis of the first side member 3, and the rotation restriction member 78 is a restriction in which the notch recess 79 and the notched portion of the notch recess 79 are bent in an arc shape. By forming with the piece 80, it can form easily only by notching a part of base end part of the 1st side member 3, and bending.

  Even when the rotation of the first side member 3 is not urged by the rotation urging spring 74, the rotation restricting member 78 has a fitting and holding effect.

  Since the concave groove 13 is formed in the bottom portion 11 of the base member 2, the shape of the bottom portion 11 is kept flat against the bending of the bottom portion 11 when an external force is applied to the binding tool 1. it can.

  A fixing hole 14 is provided in the bottom 11, and the fixing hole 14 has an insertion / removal hole 15 and a locking hole 16, so that the attachment protrusion of the file is inserted into the insertion / removal hole 15 and the binding tool 1 is rotated with respect to the file. Thus, the binding tool 1 can be easily fixed only by setting the mounting projection in the locking hole 16.

  Since the first side member 3 is attached to the upright portion 12 via the rotation biasing spring 74, the rotation biasing force can be obtained simply by releasing the pinching state of the second side member 4 to the non-pinching state. Since the first side member 3 is released by being biased by the spring 74, the attaching / detaching operation of the object to be bound is easy.

  The second side member 4 is supported by the upper holding portion 27 and the lower holding portion 28 so that the upper holding portion 27 and the lower holding portion 28 are pivotable with respect to each other. The binding plate portion 52 can be easily held by the portion 27 and the lower holding portion 28, and the holding state can be easily released.

  By providing the locking claw portion 31 in the upper clamping portion 27 and providing the locking recess portion 56 in the binding plate portion 52, the clamping state can be more reliably maintained.

  The lower holding portion 28 is provided with a receiving portion 49 and an insertion hole 48, the two tip pieces 45 are provided apart from each other, and the extension hook portion 63 and the extension convex portion 64 are provided on the binding plate portion 52. Thus, when the extension portion 61 of the binding plate portion 52 is pushed into the lower holding portion 28 in order to obtain a clamping state, the extension convex portion 64 is positioned between the two tip pieces 45, and the extension hooking portion 63 is positioned in the insertion hole 48 so that the tip is caught by the receiving portion 49, so that the binding plate portion 52 can be disposed at an appropriate position with respect to the lower holding portion 28, and when the binding plate portion 52 is pushed in. The position of the binding plate portion 52 with respect to the lower clamping portion 28 is difficult to shift and can be stably held.

  When the standing portion 12 is provided with the support portion 22 that protrudes from the part of the periphery of the notch portion 21 to the side opposite to the bottom portion 11, when the second side member 4 in the sandwiched state is in the standing state, The support portion 22 contacts a part of the lower holding portion 28 along the outside of the lower holding portion 28, and the lower holding portion 28 is supported by the support portion 22. Accordingly, the free end portion of the lower clamping portion 28 is difficult to rotate outwardly through the notch portion 21 and can prevent rattling and the like, so that it can be clamped more stably and the holding power of the binding tool 1 is improved. it can. That is, for example, even when a force greater than the weight of the object to be bound is applied due to an impact such as dropping of a file, the lower clamping portion 28 is difficult to rotate through the cutout portion 21, and the clamping state is good. It is possible to reliably hold the state in which the object to be bound is bound.

  Further, in the first side member 3 and the second side member 4 in the sandwiched state, the support portion 22 is positioned along the outside of the lower sandwiching portion 28 and supports the lower sandwiching portion 28, so that the binding in the sandwiched state is performed. The force transmitted from the plate part 52 to the lower clamping part 28 can be received by the lower clamping part 28 and the support part 22, and the strength can be improved. For example, even when the lower clamping part 28 is designed to be thin compared to the conventional one, the strength is good and a force greater than the weight of the object to be bound is applied due to an impact such as a file drop. Even so, the lower clamping portion 28 is not easily deformed or damaged. That is, even if the lower clamping portion 28 is designed to be thinner than the conventional one, the strength is not lowered compared to the conventional one, and a larger holding space for the object to be bound can be secured.

  Here, unlike the second side member 4, the first side member 3 does not have the upper side clamping part 27 and the lower side clamping part 28, and originally the support part 22 is unnecessary on the first side member 3 side. However, since the support portion 22 is also provided on the first side member 3 side, the rotation biasing spring 73 can be reliably locked, and the first side member 3 is held by the rotation biasing spring 73. Energize more reliably.

  By providing the support portion 22 for locking the rotation biasing spring 74 on the first side member 3 side, the first side member 3 side and the second side member 4 side of the base member 2 become symmetrical. Therefore, when attaching the 1st side member 3 to the base member 2, it is not necessary to distinguish the 1st side member 3 side and the 2nd side member 4 side, and it is easy to assemble the binding tool 1, and the 1st side member 3 Even when the first binding member 5 that can be removed is provided in the double-open configuration, the base member 2 can be shared, so that versatility can be improved and manufacturing costs can be reduced.

  By the engagement portion 58 having the engagement projection portion 59 provided in the binding plate portion 52 and the engaged portion 33 having the engagement hole portion 34 and the engagement restriction portion 35 provided in the upper clamping portion 27, In the clamped state, the engagement protrusion 59 engages with the engagement hole 34, and the engagement restricting portion 35 is caught in the opening 60 of the engagement protrusion 59. The engagement protrusion 59 and the engagement restricting portion 35 are hooked in the holding direction, and the movement of the second binding member 6 with respect to the second side member 4 in the holding direction can be restricted. The holding power of the binding tool 1 can be improved.

  The engagement restricting portion 35 includes a first engagement piece 36 formed by bending from a part of the flange 32 toward the engagement hole portion 34, and a free end portion of the upper clamping portion 27 in the engagement hole portion 34. Since it has a double structure along the clamping direction with the second engagement piece 37 projecting from the peripheral edge on the side toward the first engagement piece 36, the clamped state can be firmly held.

  Moreover, since the folding line 38 is formed along the clamping direction of the upper side clamping part 27, the 1st engagement piece 36 has the favorable intensity | strength of the 1st engagement piece 36, and can hold | maintain a clamping state more firmly. .

  The engagement restricting portion 35 can form the first engagement piece 36 only by bending a part of the flange 32 toward the engagement hole portion 34, and the first engagement piece 35 is based on the periphery of the engagement hole portion 34. Since the second engagement piece 37 can be formed simply by bending toward the combined piece 36, it can be easily formed without using another member.

  The first engaging piece 36 is formed in a narrow concave shape toward the center, and the engaging protrusion 59 is formed in a narrow convex shape toward the tip, and the respective shapes correspond to each other. Since the engaging protrusion 59 can slide along the first engaging piece 36 when the holding state is set, the engaging portion 58 and the engaged portion 33 can be easily engaged, and the holding state can be easily set. In addition, the clamped state can be firmly held.

  The upper clamping portion 27 is provided with a shaft slip-off preventing piece 39 so as to cover the opening on the outside of the mounting portion 30, so that the shaft 25 is moved upward by the rotation of the upper clamping portion 27 and the lower clamping portion 28. Even if it moves relative to the shaft 27, the shaft 25 contacts the shaft slip-off prevention piece 39, and the shaft support of the upper clamping portion 27 is not released. Further, since the shaft 25 does not protrude outward from the mounting portion 30 by the shaft slip-off preventing piece 39, the user is injured by the protruding shaft 25 or the protruding shaft 25 is unexpectedly caught and the binding device 1 is damaged. Can be prevented.
