  In such a binding tool, each side plate is placed in an upright state with a free end located on the side opposite to the substrate, and the binding target is inserted between each side plate and the pressing holding plate by the biasing force of the coil spring. The comb-to-be-stitched objects are clamped and held and the object to be bound is bound and held. Further, when removing the bound object to be bound, the side plates are rotated with respect to the pressing holding plate to release the clamping, and the engaged object to be bound is removed.

  Here, in the binding tool having such a configuration, since the press holding plate is attached inside the side plate and the bent portion, the distance between the press holding plates is larger than the distance between the bent portions. Will be shorter. Moreover, since the said side plate and the said press holding board are attached to the said standing part via the said coil spring, the distance between each said press holding board will become short compared with the distance between each said bending part. That is, the binding space for the object to be bound is reduced.

  Therefore, in a binding tool that can hold the first binding member or the second binding member by the upper holding part and the lower holding part, as a binding tool that prevents the reduction of the binding space, The thing of the structure which formed the notch part in this bending part is known (for example, refer patent document 2).

  In the binding tool having such a configuration, the upper holding portion is raised, and the first binding member or the second binding member is held between the upper holding portion and the lower holding portion. Since a part of the lower holding part is inserted into the notch part and is located outside the upright part via the notch part, it is possible to prevent the binding space from being reduced by providing the lower holding part. Further, since the urging means for urging the upper nip part and the lower nip part can be attached at a position corresponding to the notch part, the binding space can be reduced by attaching the urging means. Can be prevented.

  Further, in the binding tool having such a configuration, in a state where the object to be bound is bound, the outer side of the free end portion of the lower holding portion contacts the periphery of the notch portion or the base portion of the standing portion. By contacting, rotation to the outside of the lower clamping portion is restricted, and the state where the object to be bound is bound is maintained.

  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 upper clamping portion 28 and the lower clamping portion 28, the upper clamping portion 27 rotates to the lower clamping portion 28 side by the biasing force of the clamping biasing spring 29. 27 and the lower clamping part 28 are in a clamping state in which the binding plate part 52 is clamped.

  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 56 are engaged, and the engaging portion 58 and the engaged portion 33 are engaged. As a result, the engagement restricting portion 35 and the opening 60 of the engaging protrusion 59 are engaged, and the sandwiched state is maintained.

  The engagement portion of the object to be bound is inserted into and engaged with the pipe portion 54 of the first binding member 5 in such a clamped state.

  The insertion rod 55 of the second binding member 6 is fitted into the pipe portion 54 of the first binding member 5.

  In a state where the pipe portion 54 and the insertion rod 55 are fitted, the first side member 3 is rotated with respect to the upright portion 12 to be in an upright state.

  As the first side member 3 rotates, the extended portion 61 of the binding plate portion 52 of the second binding member 6 becomes the lower holding portion 28 in the same manner as when the first side member 3 is held. The second side member 4 is held in a sandwiched state.

  Here, when the clamped first side member 3 and the second side member 4 are raised, a part of the lower clamping portion 28 is located in the notch 21 and the support portion 22 of the rising portion 12 is It becomes a state along the outer side of the side clamping part 28, contacts the lower clamping part 28, and is supported.

  While the 2nd side member 4 is made into the clamping state, the 1st side member 3 and the 2nd side member 4 are made into the standing state, and the state which bound the to-be-sewn object was hold | maintained.

  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. The free end portion is rotated outward to release the clamping state and to bring it into a non-clamping state.

  In a state where the pipe portion 54 and the insertion rod 55 are fitted, the first side member 3 held together with the second binding member 6 is rotated to an open state.

  In the opened state, the fitting between the pipe portion 54 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 54.

  And in such a binding tool 1, the support part 22 which protruded from the part of the periphery of the notch part 21 to the opposite side to the bottom part 11 was provided in the standing part 12, and the 1st side of the clamping state is provided. When the member 3 and the second side member 4 are raised, 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 the support portion. 22 is supported. Therefore, 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 more stably clamped 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 support portion 22 is provided along the outside of the lower clamping portion 28. Since the lower clamping part 28 is difficult to rotate through the notch part 21 and can prevent rattling or the like, the clamping state of the first side member 3 and the second side member 4 is stable and the holding force is good. The state in which the object to be bound is bound can be maintained.

  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 thinner than the conventional one, the strength is good because the support part 22 is provided along the outside of the lower clamping part 28, Even when a force greater than the weight of the object to be bound is applied due to an impact such as a fall of the file, the lower clamping portion 28 is deformed or damaged by the force applied from the binding plate portion 52 to the lower clamping portion 28. hard. 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.

  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 clamping direction, and the first binding member 5 and the second binding member 6 with respect to the first side member 3 and the second side member 4 in the clamping direction. Since the movement can be restricted, the clamped state can be held more reliably and the holding force of the binding tool 1 can be improved.

  The engagement restricting portion 35 includes a second 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.
