Abut first. That is, the first and second ring constituent members 51 and 52 of the other binding ring 5, which is a binding ring that is located away from the one binding ring 3 to which the operation force in the closing direction is directly applied by fingers. The tip portions 51 s and 52 s push in the closing direction prior to the tip portions 31 s and 32 s of the first and second ring constituting members 31 and 32 of one binding ring 3 abutting and pressing each other. It will be.

  Next, at the stage where the tip portions of the first ring constituent members 31 and 51 and the tip portions of the second ring constituent members 32 and 52 face each other, the guide inclined surfaces 311c of the outward engaging portions 311 and 511 are provided. 511c and the guide inclined surfaces 321c and 521c of the inward engagement portions 321 and 521 come into contact with each other. When the operating force in the closing direction is further applied to the ring component members 31, 51, 32, 52 from this state, the outward engaging portions 311, 511 are guided by the guiding action of the guide inclined surfaces 311c, 511c, 321c, 521c. The first ring constituent members 31, 51 having the inner ring are temporarily elastically displaced inward and the second ring constituent members 32, 52 having the inward engaging portions 321, 521 are temporarily Will be elastically displaced outward. Then, when the outwardly engaging portions 311 and 511 and the protrusions 311a, 511a, 321a, and 521a of the inwardly engaging portions 321 and 521 get over each other, the outwardly protruding portions of the engaging portions 311 and 511 311a and 511a are fitted into the recesses 321b and 521b of the inward engagement portions 321 and 521, and the protrusions 321a and 521a of the inward engagement portions 321 and 521 are the recesses 311b of the outward engagement portions 311 and 511. 511b to complete the engagement. As a result, both the binding rings 3 and 5 are held in the closed state even when the hands are released from one binding ring 3.

That is, the inclining guides 311c and 511c of the outward engagement portions 311 and 511 provided on the first ring constituent members 31 and 51 and the inward engagement provided on the second ring constituent members 32 and 52, respectively. When both ring constituent members 31 and 32 in one binding ring 3 are further operated in the closing direction while the guide inclined surfaces 321c and 521c of the joint portions 321 and 521 are in contact with each other, the guide inclined surfaces 311c, 511c and 321c are operated. As a result of the guiding action of 521c, the two first ring constituent members 31, 51 fall in the direction of approaching, and the two second ring constituent members 32, 52 cause the action of falling in the direction of separating from each other. The operation of tilting in the direction in which the two first ring constituent members 31 and 51 come together is that the first connecting plate 11 supporting both the first ring constituent members 31 and 51 bends downward. That is, it is caused by the fact that the longitudinal central portion of the first connecting plate 11 bends in the direction of downward displacement. The operation in which the two second ring constituent members 32 and 52 are tilted away from each other is caused by the second connecting plate 12 supporting both the second ring constituent members 32 and 52 being bent upward. That is, it is caused by the fact that the central portion in the longitudinal direction of the second connecting plate 12 bends in the direction of displacement upward.

Since it is formed so as to face, the separation distance w2 between the front end portion 51s of the first ring constituent member 51 and the front end portion 52s of the second ring constituent member 52 in the other binding ring 5 is one binding ring 3. Can be set shorter than the separation distance w1 between the distal end portion 31s of the first ring constituent member 31 and the distal end portion 32s of the second ring constituent member 32. Compared to the conventional one, the other binding rings 5 can be set. In Kicking will give a greater force when engaging the ring component 51, 52 to each other. Therefore, the ring component members 32 and 52 of the other binding ring 5 can be more reliably engaged by operating the one binding ring 3 in the closing direction. Therefore, as described above, the engagement between the engaging portions 321 and 521 of the first and second ring constituent members 32 and 52 on the other binding ring 5 side can be performed with a force larger than that of the conventional one, Conventional problems can be more reliably suppressed or prevented. In other words, according to the configuration of the present embodiment, only one binding ring 3 positioned in front of the user is picked and operated in the closing direction, so that the other binding ring 5 can be changed to one binding ring 3. The applied operating force can be transmitted more reliably, and the other binding ring 5 is driven to smoothly and reliably engage the engaging portions 321 and 521 of the ring constituent members 32 and 52 in the other binding ring 5. Can be combined.

  As described above, the binding tool G according to the present embodiment is obtained by twisting and deforming both the first and second connecting plates 11 and 12, and the first binding ring 5 in the other binding ring 5 is in the open position. The separation distance w2 between the tip 51s of the ring component 51 and the tip 52s of the second ring component 52 is such that the tip 31s of the first ring component 31 and the second ring in the first binding ring 3 are separated. Since it is set to be shorter than the separation distance w1 from the distal end portion 32s of the component member 32, even when the closing operation is performed so that only one binding ring 3 is pinched with fingers, the engaging portions 511 of the other binding rings 5; It is possible to secure a moving distance necessary for the engagement of the two 521s, and it is possible to secure an operation force necessary for the engagement of the engaging portions 511 and 521 of the other binding rings 5. Purpose of Can achieve the object of providing a binding device G capable KazuSatoshi be engineered by one of the binding rings 3 are engaged also an engaging portion 511 and 521 to each other of the other binding rings 5.

  Since the first and second connecting plates 11 and 12 are made of metal, the plastic deformation can be performed relatively easily, and the elastic urging force and strength are excellent even in a compact size. It has become.

  Since the first and second connecting plates 11 and 12 are each torsionally deformed, the intended purpose can be realized with a small amount of deformation as compared with a case in which only one of them is deformed.

  Upper surfaces 11b and 12b in the vicinity of the portions P2 and P4 supporting the first and second ring constituent members 51 and 52 of the other binding rings 5 in the first and second connecting plates 11 and 12 are the first, It forms so that it may face inward rather than the upper surfaces 11a and 12a of the vicinity of the parts P1 and P3 which are supporting the 1st, 2nd ring structural members 31 and 32 of the 1 binding ring 3 in the 2nd connection plates 11 and 12. Therefore, in the open position, the separation distance w2 between the front end portion 51s of the first ring constituent member 51 and the front end portion 52s of the second ring constituent member 52 in the other binding ring 5 is equal to one binding ring 3. The structure which is set shorter than the separation distance w1 between the front end portion 31s of the first ring constituent member 31 and the front end portion 32s of the second ring constituent member 32 can be realized relatively easily. That is, the base end portions 312 and 512 of the first ring constituent members 31 and 51 in the binding rings 3 and 5 are respectively relative to the upper surfaces 11a and 11b of the portions P1 and P2 supported by the first connecting plate 11. They can be attached at substantially the same angle, and the base end portions 322 and 522 of the second ring constituent members 32 and 52 in the binding rings 3 and 5 are portions of the portions P3 and P4 supported by the second connecting plate 12. Since it can be attached to the upper surfaces 12a and 12b at substantially the same angle, the binding rings 3 and 5 can be attached to the first and second connecting plates 11 and 12 without requiring extremely fine angle adjustment. Can be done in a unified and common way, and contribute to product stability. In addition, in the present embodiment, the angle is set to be substantially vertical, that is, approximately 90 degrees, so that the binding rings 3 and 5 can be suitably attached to the connection plates 11 and 12 as well as being attached. The accuracy of the is also excellent.

  Further, the file F according to the present embodiment is formed by attaching the above-described binding tool G, and is a user-friendly file F that can be reliably closed by one hand operation. Can be realized.

  The present invention is not limited to the embodiment described in detail above.

  In the present embodiment, the first and second connecting plates are both twisted and deformed. However, the present invention is not limited to this, and only one of the first and second connecting plates is twisted and deformed. It may be.

  The elastic biasing means is not limited to that of the present embodiment. For example, a spring is installed between both side edges of the cover, and the working end of the spring is elastically pressed against the lower surface of the connecting plate. It may be a thing.

  In the present embodiment, a binding tool in which there is one binding ring and one other binding ring has been described, but there may be a plurality of one binding ring and other binding rings.

  The shape of the binding ring is not limited to this embodiment, and may be any shape that forms a loop in the closed state. For example, various types such as a round (O-type) ring and an oval ring are conceivable.

  The shape and direction of the engaging portion of each ring constituent member can also be set as appropriate, and are not limited to the mode shown in the present embodiment.

  The use direction of the file may not be clearly defined, and the attachment direction of the binding ring is not limited. As shown in the present embodiment, if the binding tool is attached to the cover with the use direction determined so that one binding ring is positioned in front of the operator, the closing operation should be performed.
