Description

本発明は、簡単な操作によってロック状態を解除することが可能な綴じ具、及びその綴じ具が適用されるファイルに関するものである。 The present invention relates to a binding tool that can be unlocked by a simple operation, and a file to which the binding tool is applied.

従来より、ファイル等に適用されるベースと、ベースとの間に紙葉類を押さえた状態で綴じ込み可能な押さえ部と、押さえ部を綴じ込み状態と非綴じ込み状態に操作可能な操作部と、綴じ込み状態において操作部の移動を規制するロック機構とを具備するレバー式の綴じ具が知られている。 Conventionally, a base that is applied to a file or the like, a pressing portion that can be bound with a paper sheet held between the base, an operation portion that can operate the pressing portion in a binding state and a non-binding state, and binding 2. Description of the Related Art A lever-type binding tool that includes a lock mechanism that restricts movement of an operation unit in a state is known.

この種の綴じ具としては、操作部を上方から押し込む方向に力を付与するとともに、操作部を水平方向に移動させる方向に力を同時に付与することによりロック状態にあるロック機構を非ロック状態に操作することができるように構成されているものが挙げられる（例えば特許文献１参照）。 As this type of binding tool, a force is applied in a direction in which the operation unit is pushed in from above, and a lock mechanism in a locked state is brought into an unlocked state by simultaneously applying a force in a direction in which the operation unit is moved in the horizontal direction. The thing comprised so that it can operate is mentioned (for example, refer patent document 1).

また、改良品として、操作部に異なる２つの操作領域を設け、一方の操作領域を押し込む方向に操作力を付与することによりロック状態になるようにするとともに、他方の操作領域を押し込む方向に操作力を付与することにより非ロック状態になるように構成されているものが考えられている（例えば特許文献２参照）。
実公平５−２９９０５号公報（第１〜３頁、第１図、第２図）特開２００２−２４８８８３号公報（第１〜４頁、第１図、第２図） In addition, as an improved product, two different operation areas are provided in the operation unit, and an operation force is applied in the direction in which one of the operation areas is pushed in, so that the locked state is achieved and the other operation area is pushed in. One configured to be in an unlocked state by applying a force is considered (for example, see Patent Document 2).
Japanese Utility Model Publication No. 5-29905 (pages 1 to 3, FIGS. 1 and 2) Japanese Patent Laid-Open No. 2002-248883 (pages 1 to 4, FIGS. 1 and 2)

ところが、特許文献１記載の綴じ具は、上記の通り、ロック状態を解除する場合には、操作部を上方から押し込む方向に力を付与するとともに、操作部を水平方向に移動させる方向に力を同時に付与しなければならないため、操作方向が二方向となって操作の簡便性が損なわれるという不都合が生じる。また、操作部を水平方向に移動させる方向に力を付与する際に指が操作部が外れてしまい、操作部が不意に跳ね上がったりする等、動作の安全性に欠け、今ひとつ使い勝手に優れないものである。 However, as described above, the binding tool described in Patent Document 1 applies a force in a direction to push the operation unit from above and releases a force in a direction to move the operation unit in the horizontal direction when releasing the locked state. Since they must be given at the same time, there is a disadvantage that the operation direction becomes two directions and the simplicity of operation is impaired. In addition, when applying force in the direction to move the operation unit horizontally, the operation unit is unsafe, such as a finger coming off the operation unit, and the operation unit jumping up unexpectedly. It is.

また、特許文献２記載の綴じ具は、操作部を上方から押し込む方向に力を付与するだけでロック状態と非ロック状態に操作可能であるが、押し込む方向に付与された力に基づく上下方向のスライド動作を左右方向のスライド動作に変換させることによりロック機構をロック状態と非ロック状態に操作可能に構成したものであるため、操作によっては変換がスムーズに行えない場合等もあり動作の安定性に欠けるものである。また、スライド動作を変換させる適宜の変換機構の構造が複雑であり、このような変換機構を設けるために綴じ具自体の構造が複雑なものとなり、製作工程の複雑化、コストの増加を招来するという不具合が生じる。また、ロック状態から非ロック状態に操作する場合には、ベースに対して略水平姿勢にある操作部をさらに下方へ押し下げて上下方向のスライド動作を左右方向のスライド動作に変換させるように構成しているため、操作部の下方に、操作部のストロークを確保する一定の空間を形成しなければならない等設計の自由度がある程度規制されるものである。さらに、特許文献２記載のものは、押さえ部や操作部を合成樹脂素材を用いて形成したものであるため、廃棄時に、押さえ部と金属性素材からなる他の部材とを分別しなければならず面倒である。 In addition, the binding tool described in Patent Document 2 can be operated in a locked state and an unlocked state only by applying a force in a direction in which the operation unit is pushed in from above, but in the vertical direction based on the force applied in the pushing direction. Since the lock mechanism can be operated in the locked and unlocked states by converting the slide operation into a left and right slide operation, the conversion may not be performed smoothly depending on the operation. Is lacking. In addition, the structure of an appropriate conversion mechanism for converting the slide operation is complicated, and the structure of the binding tool itself becomes complicated because of providing such a conversion mechanism, which leads to a complicated manufacturing process and an increase in cost. The problem that occurs. In addition, when operating from the locked state to the unlocked state, the operation unit that is substantially horizontal with respect to the base is further pushed downward to convert the vertical sliding motion into the horizontal sliding motion. Therefore, the degree of freedom of design is restricted to some extent, for example, a certain space for securing the stroke of the operation unit must be formed below the operation unit. Furthermore, since the thing of patent document 2 forms the holding | suppressing part and the operation part using the synthetic resin material, at the time of disposal, you have to separate a holding | maintenance part and other members consisting of a metallic material. It is troublesome.

また、改良品として、ロック機構を、ベースの起立壁に側方に突出するように設けた係合爪と、操作部が起き上がる方向に力を付勢する付勢手段の一端部を延長させ係合部に係合可能な係合軸とから構成し、係合軸と係合爪とを係合させることによりロック状態になるとともに、所定の操作に対応して係合軸が移動して前記係合爪との係合状態を解除することにより非ロック状態になるように設定したものが考えられる。しかしながら、このようなものは、上記構成上、ロック解除操作時に、係合軸と係合爪との係合を解除するために係合軸を係合爪の形状に倣わせて一時的に軸心に略直行する平面（回転面）から外れるように移動させなければならない。その結果、係合軸の動作が不安定なものとなり易く、良好な操作感を得ることができず、実用性に欠けるものとなる。このような不具合はロック操作時も同様に生じる。 In addition, as an improved product, the lock mechanism is extended by engaging claws provided on the standing wall of the base so as to protrude sideways, and one end of the biasing means for biasing the force in the direction in which the operation unit rises. The engagement shaft is engageable with the joint portion, and the engagement shaft and the engagement pawl are engaged to be in a locked state, and the engagement shaft is moved in response to a predetermined operation. A device that is set to be in an unlocked state by releasing the engaged state with the engaging claw is conceivable. However, in this configuration, in order to release the engagement between the engagement shaft and the engagement claw during the unlocking operation, such a configuration temporarily moves the engagement shaft to follow the shape of the engagement claw. It must be moved away from a plane (rotation plane) that is substantially perpendicular to the heart. As a result, the operation of the engagement shaft is likely to be unstable, a good operational feeling cannot be obtained, and the practicality is lacking. Such a problem also occurs during the lock operation.

本発明は、このような課題に着目してなされたものであって、主たる目的は、簡単な操作によってロック状態を解除することができるともに、安定かつ良好な操作感を得ることが可能な綴じ具、及びその綴じ具が適用されるファイルを提供することにある。 The present invention has been made paying attention to such a problem, and a main purpose thereof is a binding capable of releasing a locked state by a simple operation and obtaining a stable and good operation feeling. It is to provide a tool and a file to which the binding tool is applied.

すなわち、本発明の綴じ具は、ベースと、このベースとの間に紙葉類を押さえた状態で綴じ込み可能な押さえ部と、この押さえ部を綴じ込み状態と非綴じ込み状態との間で操作可能な操作部と、前記綴じ込み状態において前記操作部の移動を規制するロック機構とを具備してなり、前記操作部に対する所定の操作力により前記ロック機構をロック状態と非ロック状態との間で操作可能に構成したものであって、前記操作部が、前記ベースに対して回動可能に設けられた操作部本体と、この操作部本体の軸心と平行な軸心を中心に回動可能な操作部本体に片持ち的に支持され、前記ロック状態を解除して前記非ロック状態に操作可能なロック解除部とを備えたものであり、前記ロック機構が、前記ロック解除部に設けた第１係合部と、前記ベースに設けられ前記ロック状態において前記第１係合部に係合し得る第２係合部とを備えてなり、前記ロック解除部を押し込む方向のみに与えられた操作力に基づいて前記ロック解除部が回動し、それに伴って前記第1係合部が回転面内から外れることなく前記第１係合部の前記第２係合部に対する相対位置が変位することにより、前記第１係合部と前記第２係合部との係合が解除され前記非ロック状態になるように構成していることを特徴とする。また、本発明に係るファイルは、以上のような構成を有する綴じ具と、この綴じ具が取り付けられる表紙体とを具備するものである。 That is, the binding tool of the present invention is operable between the base, the pressing portion that can be bound with the paper sheet being pressed between the base, and the pressing portion between the binding state and the non-binding state. An operation unit and a lock mechanism for restricting movement of the operation unit in the binding state are provided, and the lock mechanism can be operated between a locked state and an unlocked state by a predetermined operation force on the operation unit. The operation unit is configured to be rotatable with respect to an operation unit main body provided rotatably with respect to the base, and an axis parallel to the axis of the operation unit main body. And a lock release portion that is cantilevered by the main body and can be operated in the unlocked state by releasing the locked state, and the lock mechanism is provided in the lock releasing unit. An engaging portion; And a second engagement portion that can be engaged with the first engagement portion in the locked state, and the lock release portion is based on an operation force applied only in a direction of pushing in the lock release portion. The first engaging portion is displaced by the relative position of the first engaging portion with respect to the second engaging portion without being displaced from the rotation surface. And the second engagement portion are released and the unlocked state is established. The file according to the present invention includes a binding tool having the above-described configuration and a cover body to which the binding tool is attached.

ここで、「回転面」とは軸心に略直交する平面を意味する。このようなものであれば、ロック解除部を押し込むという簡単な操作によってロック状態を解除することが可能であり、しかも、ロック解除操作時に、第１係合部が、回転面内から外れることがないため、ロック解除操作時に係合軸が一時的に回転面内から外れるものと比較して、第１係合部の動作を単純化することができ、確実なロック解除動作を実現し、安定かつ良好な操作感を得ることができる。また、ロック解除部が操作部本体の軸心と平行な軸心を中心に操作部本体に対して回動可能に設けられているため、直感的に把握し得るロック解除操作時に付与する操作力の方向と、実際に付与する操作力の方向が一致し、使い勝手に優れたものとなる。加えて、ロック機構が、第１係合部と第２係合部とから構成しているため、操作部に例えば上下方向のスライド動作を左右方向へのスライド動作に変換するカム等の比較的構造が複雑な変換部を設ける必要がなく、簡素な構造を用いることができ、製作工程の簡素化、コストの削減に資する。 Here, the “rotation plane” means a plane substantially orthogonal to the axis. If it is such, it is possible to release the locked state by a simple operation of pushing in the unlocking part, and the first engaging part may be disengaged from the rotation surface during the unlocking operation. As a result, the operation of the first engagement portion can be simplified as compared with the case where the engagement shaft temporarily disengages from the rotation surface during the unlocking operation, realizing a reliable unlocking operation and stable. And a favorable operation feeling can be obtained. In addition, since the unlocking part is provided so as to be rotatable with respect to the operating part body about an axis parallel to the axial center of the operating part body, the operating force applied during the unlocking operation that can be intuitively grasped And the direction of the operating force to be actually applied are the same, and it is easy to use. In addition, since the lock mechanism is composed of the first engagement portion and the second engagement portion, the operation portion is relatively free of a cam or the like that converts, for example, a vertical sliding motion into a horizontal sliding motion. There is no need to provide a converter having a complicated structure, and a simple structure can be used, which contributes to simplification of the manufacturing process and cost reduction.

ロック操作の簡便性をも有効に図るためには、前記操作部本体を押し込む方向のみに与えられた操作力に基づいて前記操作部本体が回動し、それに伴って前記第１係合部が回転面内から外れることなく前記第２係合部に係合することにより前記ロック状態になるように構成すればよい。 In order to effectively achieve the locking operation, the operation unit body is rotated based on an operation force applied only in the direction in which the operation unit body is pushed, and the first engagement unit is moved accordingly. What is necessary is just to comprise so that it may be in the said locked state by engaging with the said 2nd engaging part, without removing from the inside of a rotating surface.

具体的な実施態様としては、前記第２係合部を、前記ベースに上方に向けて突出するように設けるとともに、前記第１係合部を、前記ロック解除部のうち、前記操作部本体に支持されている取付端部側に下方に向けて突出するように設けているものが挙げられる。このようなものであれば、ロック解除部の先端部（自由端）を押し込む方向に操作力を付与することにより第１係合部が浮き上がる方向に回動し、第１係合部と第２係合部との係合を確実に解除することができる。 As a specific embodiment, the second engagement portion is provided so as to protrude upward from the base, and the first engagement portion is provided on the operation portion main body of the lock release portion. The thing provided so that it may protrude toward the downward direction to the attachment end part side currently supported is mentioned. If it is such, it will rotate in the direction which a 1st engagement part floats by giving an operating force in the direction which pushes the front-end | tip part (free end) of a lock release part, and a 1st engagement part and a 2nd Engagement with the engaging portion can be reliably released.

また、前記操作部が起き上がる方向に力を付勢する付勢手段の一端部を、前記ロック解除部のうち、前記操作部本体に支持されている取付端部を通過する位置まで延出させていれば、操作力が付与されていない状態においてロック解除部が下方に不意に沈み込むことを防止することができる。 Further, one end portion of the biasing means that biases the force in the direction in which the operation portion rises is extended to a position that passes through the attachment end portion supported by the operation portion main body in the lock release portion. If this is the case, it is possible to prevent the unlocking portion from sinking downward in a state where no operating force is applied.

第２係合部を簡単に形成するためには、前記第２係合部が、前記ベースの一部を斜め上方に切り起こした切り起し片と、この切り起し片の先端部を斜め下方に折り曲げてなる折り曲げ片とを備えたものであればよく、また、前記操作部本体を押し込む方向のみに与えられた操作力に基づき、前記第１係合部が前記折り曲げ片に接触しながら下方にスライド移動し、前記第１係合部が前記折り曲げ片を乗り越えた際に、前記操作部が起き上がる方向に力を付勢する付勢手段を利用して前記第１係合部が前記第２係合部に係合することにより前記ロック状態になるように構成すれば、折り曲げ片が第１係合部の移動を案内するガイド部として機能し、第１係合部の動作の安定性を有効に高めることができる。 In order to easily form the second engaging portion, the second engaging portion includes a cut-and-raised piece obtained by cutting and raising a part of the base obliquely upward, and an end portion of the cut-and-raised piece obliquely. It only has to be provided with a bent piece that is bent downward, and the first engagement portion is in contact with the bent piece based on the operating force applied only in the direction in which the operation portion main body is pushed. When the first engaging portion slides downward and the first engaging portion climbs over the bent piece, the first engaging portion is If the second engaging portion is configured to be in the locked state, the bent piece functions as a guide portion that guides the movement of the first engaging portion, and the stability of the operation of the first engaging portion. Can be effectively increased.

前記操作部本体の所定部位に他の領域より低位置となるように窪ませてなる凹段部を設けるとともに、この凹段部の所定部位に前記ロック解除部の一部が表出し得る窓部を設け、当該窓部を通じて前記ロック解除部の一部を表出させるようにロック解除部を操作部本体に取り付けたものであれば、第１係合部と第２係合部との係合が解除された際、操作力を付与した指が操作部本体の一部に当たるため、操作部が不意に跳ね上がることを防止することができ、動作の安全性に優れ、使い勝手に優れたものとなる。 A window portion that is provided with a recessed step portion that is recessed at a predetermined portion of the operation portion main body so as to be lower than other regions, and a portion of the unlocking portion can be exposed to the predetermined portion of the recessed step portion. If the lock release part is attached to the operation part main body so that a part of the lock release part is exposed through the window part, the engagement between the first engagement part and the second engagement part When the is released, the finger to which the operating force is applied hits a part of the main body of the operation unit, so that the operation unit can be prevented from jumping up unexpectedly, and the operation is safe and easy to use. .

製作工程の簡素化を図るためには、前記窓部が、前記操作部本体の所定部位を切り欠いて形成したものでればよい。 In order to simplify the manufacturing process, the window portion may be formed by cutting out a predetermined portion of the operation portion main body.

ロック解除部の取付位置としては、上記の実施態様の他に、前記ロック解除部を、前記操作部本体の自由端部に取り付けている態様であっても構わない。このようなものであれば、ロック解除部の一端部（先端部）が完全にフリーな状態となるため、ロック解除部を押し込む方向のみに操作力を付与した場合に、操作力を付与した指が操作部本体に干渉することがなく、ロック解除時の操作性を良好なものとすることができる。 As an attachment position of the unlocking portion, in addition to the above embodiment, the unlocking portion may be attached to the free end of the operation portion main body. If this is the case, one end (tip portion) of the unlocking portion is completely free, so that when the operating force is applied only in the direction in which the unlocking portion is pushed, Does not interfere with the operation unit main body, and the operability at the time of unlocking can be improved.

前記ベース、前記押さえ部及び前記操作部が金属製素材からなる折り曲げ成形品であれば、廃棄時に綴じ具自体を各部材毎に分解して分別廃棄する必要がない。加えて、合成樹脂素材からなるものと比較して耐久性にも優れたものとなる。 If the base, the pressing part, and the operation part are bent molded products made of a metal material, it is not necessary to disassemble the binding tool itself for each member at the time of disposal and dispose of it separately. In addition, it is excellent in durability as compared with a synthetic resin material.

以上説明したように本発明の綴じ具及びこの綴じ具を適用したファイルによれば、ロック解除部を一方向に押し込むという簡単な操作によってロック状態を解除することが可能であるだけでなく、ロック機構の一部を構成する第１係合部がロック解除操作時に回転面内でのみ移動するように設定しているため、第１係合部のより安定した動作を実現し、ロック解除の操作がスムーズになり、操作の簡便性を有効に図ることができる。また、ロック解除部が操作部本体に対して操作部本体の軸心と平行な軸心を中心に回動可能に設けられているため、直感的に把握し得るロック解除操作時に付与する操作力の方向と、実際に付与する操作力の方向が同一となり、使い勝手に優れたものとなる。さらに、ロック機構が、第１係合部と第２係合部とから構成しているため、操作部に例えば上下方向のスライド動作を左右方向へのスライド動作に変換するカム等の比較的構造が複雑な変換部を設ける必要がなく、簡素な構造を用いることができ、製作工程の簡素化、コストの削減に資する。 As described above, according to the binding tool of the present invention and the file to which the binding tool is applied, not only can the lock state be released by a simple operation of pushing the unlocking part in one direction, but also the lock Since the first engaging portion that constitutes a part of the mechanism is set to move only within the rotation surface during the unlocking operation, the first engaging portion can be operated more stably, and the unlocking operation can be performed. Becomes smooth, and the convenience of operation can be effectively achieved. In addition, since the unlocking portion is provided so as to be rotatable about the axis parallel to the axis of the operation unit main body with respect to the operation unit main body, the operation force applied during the unlocking operation that can be intuitively grasped And the direction of the operating force to be actually applied are the same, and it is easy to use. Furthermore, since the lock mechanism is composed of the first engagement portion and the second engagement portion, the operation portion has a relatively structure such as a cam that converts a vertical sliding motion into a horizontal sliding motion, for example. However, it is not necessary to provide a complicated converter, and a simple structure can be used, which contributes to simplification of the manufacturing process and cost reduction.

次に、上記各部材からなる綴じ具１の組み立て手順について説明する。 Next, an assembling procedure of the binding tool 1 composed of the above members will be described.

先ず、押さえ部３を、図２等に示すように、略クランク型の連結軸Ｃを介してベース２に一体的に取り付ける。具体的には、各連結軸Ｃの一端部を押さえ部３に形成した第１軸受孔３１に挿入するとともに、他端部をベース本体２１の支持壁２１５に形成した挿入孔２１５ａ及び起立壁２２に形成した挿入孔２２ａに挿入する。なお、連結軸Ｃの両端部には例えば組み立てカシメ加工を施し、連結軸Ｃの抜脱を防止している。次いで、ばね部材５の屈曲軸５１を押さえ部３に形成した第２軸受孔３２に挿入するとともに、コイル状部５２を、支持壁２１６と起立壁２２との間に位置させる。引き続き、コイル状部５２の両端に、操作部本体４１の各側面部４１２、４１３に形成した挿入孔４１Ｎが位置するように操作部本体４１を配置し、これら挿入孔４１Ｎと支持壁２１６及び起立壁２２に形成した各挿入孔２１６ａ、２２ａとを一致させて固定ピンＮを挿入することにより、ベース２、押さえ部３及び操作部４をばね部材５を介して一体的に取り付ける。そして、既述した手順により前記ロック解除部４２を操作部本体４１に片持ち的に取り付けるとともに、ばね部材５の直線軸５３を操作部本体４１の延出片４１Ｅに係合させ、直線軸５３の下方への抜脱を規制する。最後に、前記ベース２の起立壁２２の外側に突き出る固定ピンＮの先端部をかしめる等の適宜の固定手段を用いることにより固定ピンＮの脱落を防止する。以上の手順により組み立ててなる綴じ具１において、操作部本体４１は固定ピンＮを軸心ｍ１として回転可能に設けられ、この軸心ｍ１と、前述したロック解除部４２の軸心ｍ２とは平行をなすように設定してある。 First, as shown in FIG. 2 etc., the holding | suppressing part 3 is integrally attached to the base 2 via the connection shaft C of a substantially crank type. Specifically, one end portion of each connecting shaft C is inserted into the first bearing hole 31 formed in the holding portion 3, and the other end portion is inserted into the support wall 215 of the base body 21 and the upright wall 22 and the standing wall 22. It is inserted into the insertion hole 22a formed in the above. Note that, for example, assembly caulking is applied to both ends of the connecting shaft C to prevent the connecting shaft C from being pulled out. Next, the bending shaft 51 of the spring member 5 is inserted into the second bearing hole 32 formed in the pressing portion 3, and the coiled portion 52 is positioned between the support wall 216 and the standing wall 22. Subsequently, the operation portion main body 41 is arranged so that the insertion holes 41N formed in the side surface portions 412 and 413 of the operation portion main body 41 are positioned at both ends of the coil-shaped portion 52. These insertion holes 41N, the support walls 216, and the uprights are raised. By inserting the fixing pin N so that the insertion holes 216 a and 22 a formed in the wall 22 are aligned, the base 2, the pressing portion 3, and the operation portion 4 are integrally attached via the spring member 5. Then, the unlocking part 42 is cantileverly attached to the operation part main body 41 according to the procedure described above, and the linear shaft 53 of the spring member 5 is engaged with the extending piece 41E of the operation part main body 41 so that the linear shaft 53 is engaged. The downward withdrawal of the is regulated. Finally, the fixing pin N is prevented from falling off by using an appropriate fixing means such as caulking the tip of the fixing pin N protruding outside the upright wall 22 of the base 2. In the binding tool 1 assembled by the above procedure, the operation unit main body 41 is rotatably provided with the fixing pin N as the axis m1, and the axis m1 and the axis m2 of the lock release unit 42 described above are parallel. It is set to make.

次に、このような構成を有する綴じ具１の操作方法及び作用を、図５及び図６を参照して説明する。 Next, an operation method and operation of the binding tool 1 having such a configuration will be described with reference to FIGS. 5 and 6.

先ず、操作部４が起き上がっている状態（図５（ａ））において、使用者が操作部本体４１の自由端部側に設けた突部４１１ａからなる押下指示部を押圧することによって、操作部４をベース本体２１側に押し込む方向に操作力Ｆ１が付与される。この操作力Ｆ１に基づいて、操作部４１が軸心ｍ１を中心にベース本体２１に対して略水平姿勢となる方向に回転し、経過的にロック解除部４２の第１係合部４２Ｋが、ベース２の第２係合部２１Ｋに当接する（同図（ｂ））。具体的には、第１係合部４２Ｋの係合爪４２Ｋｂが、第２係合部２１Ｋの折り曲げ片２１Ｋｂに当接する。引き続き、前記操作力Ｆ１により、係合爪４２Ｋｂが、折り曲げ片２１Ｋｂに接触しながら軸心ｍ２に略直交する平面、すなわち回転面内から外れることなく折り曲げ片２１Ｋｂに沿って斜め下方にスライド移動し、係合爪４２Ｋｂが折り曲げ片２１Ｋｂを乗り越えたときに、係合爪４２Ｋｂが前記ばね部材５の付勢力を利用して折り曲げ片２１Ｋｂの下端に係合する（図６（ｃ））。なお、係合爪４２Ｋｂが折り曲げ片２１Ｋｂを乗り越えてもなお前記操作力Ｆ１を付与し続けた場合、第２係合部２１Ｋの上端部（切り起し片２１Ｋａと折り曲げ片２１Ｋｂとの境界部位）とロック解除部４２の傾斜面部４２２とが当接する前に、ベース２の起立片２２に形成した規制部２２１と操作部本体４１の一部（第１側面部４１２）とが当接するように設定し、操作部本体４１のそれ以上の回動動作を規制するとともに、ロック解除部４２のそれ以上の下方への沈み込みを抑止している（図示省略）。これにより、ロック解除部４２と第２係合部２１Ｋとが当接した場合に生じ得る第２係合部２１Ｋの変形を防止している。以上の操作により、操作部４の上方への回転移動が規制されるロック状態となる。この操作に連動して、押さえ部３の下端がベース本体２１に当接または近接する位置に移動して、紙葉類Ｐを綴じ込み得る綴じ込み状態となる。 First, in a state where the operation unit 4 is raised (FIG. 5A), the user presses a pressing instruction unit including a protrusion 411 a provided on the free end side of the operation unit main body 41, thereby operating the operation unit. The operating force F1 is applied in the direction in which the 4 is pushed into the base body 21 side. Based on the operating force F1, the operating portion 41 rotates about the axis m1 in a direction that assumes a substantially horizontal posture with respect to the base body 21, and the first engaging portion 42K of the unlocking portion 42 gradually passes, It abuts against the second engagement portion 21K of the base 2 (FIG. 2B). Specifically, the engaging claw 42Kb of the first engaging portion 42K comes into contact with the bent piece 21Kb of the second engaging portion 21K. Subsequently, by the operation force F1, the engaging claw 42Kb slides obliquely downward along the bent piece 21Kb without coming out of the plane substantially perpendicular to the axis m2 while contacting the bent piece 21Kb, that is, within the rotation plane. When the engaging claw 42Kb gets over the bent piece 21Kb, the engaging claw 42Kb engages with the lower end of the bent piece 21Kb using the biasing force of the spring member 5 (FIG. 6C). In addition, even if the engaging claw 42Kb gets over the bent piece 21Kb, when the operation force F1 is still applied, the upper end portion of the second engaging portion 21K (the boundary portion between the cut and raised piece 21Ka and the bent piece 21Kb). The control portion 221 formed on the upright piece 22 of the base 2 and a part (first side surface portion 412) of the operation portion main body 41 are set in contact with each other before the inclined surface portion 422 of the lock release portion 42 contacts. In addition, the operation portion main body 41 is further prevented from rotating, and the unlocking portion 42 is prevented from sinking further downward (not shown). Thereby, the deformation | transformation of the 2nd engaging part 21K which may arise when the lock release part 42 and the 2nd engaging part 21K contact | abut is prevented. As a result of the above operation, a locked state in which the rotational movement of the operation unit 4 upward is restricted. In conjunction with this operation, the lower end of the pressing portion 3 moves to a position in contact with or close to the base main body 21 to enter a binding state in which the paper sheet P can be bound.

また、ロック状態を解除（非ロック状態に）するには、ロック解除部４２の表出部４２１に設けた突部４２１ｃからなる押下指示部を上方から押圧すればよい。押下指示部を押圧することによって、ロック解除部４２をベース本体２１側に押し込む方向に操作力Ｆ２が付与される（同図（ｄ））。この操作力Ｆ２に基づいて、ロック解除部４２が操作部本体４１の軸心ｍ１と平行な軸心ｍ２を中心に回転動作を行う。具体的には、軸心ｍ２を中心に、表出部４２１が下方に向かって沈み込む方向に回動するとともに、第１係合部４２Ｋが上方に向かって浮き上がる方向に回動する。これにより、第１係合部４２Ｋが、回転面内から外れることなく第２係合部２１Ｋから離反する方向に移動し、係合爪４２Ｋｂと折り曲げ片２１Ｋｂとの係合が解除される。その結果、第１係合部４２Ｋと第２係合部２１Ｋとの係合状態が解除され、非ロック状態となる。非ロック状態になると同時に、操作部４がばね部材５の付勢力（復元力）によって起き上がろうとするが、操作部本体４１の自由端部側が操作力を付与した指に当接し、操作部４の不意な跳ね上がりを防止している。そして、この非ロック状態において、ロック解除部４２への操作力Ｆ２の付与を停止した場合、操作部本体４１及びロック解除部４２がばね部材５の付勢力（復元力）によって起き上がり、操作部４がベース２から離間した初期の位置に復帰する（図５（ａ））。これに伴って押さえ部３もベース本体２１から離間して前記綴じ込み状態を解除した状態（非綴じ込み状態）となる。 In addition, in order to release the locked state (to bring it into the unlocked state), it is only necessary to press the pressing instruction unit including the protrusion 421c provided on the exposed portion 421 of the unlocking unit 42 from above. By pressing the pressing instruction unit, an operating force F2 is applied in a direction in which the lock release unit 42 is pushed into the base body 21 side ((d) in the figure). Based on this operating force F2, the lock release part 42 rotates around an axis m2 parallel to the axis m1 of the operating part body 41. Specifically, around the axis m2, the exposed portion 421 rotates in a direction that sinks downward, and the first engaging portion 42K rotates in a direction that rises upward. As a result, the first engaging portion 42K moves in a direction away from the second engaging portion 21K without being disengaged from the rotation surface, and the engagement between the engaging claw 42Kb and the bent piece 21Kb is released. As a result, the engaged state between the first engaging portion 42K and the second engaging portion 21K is released, and the unlocked state is established. At the same time as the unlocked state, the operation unit 4 tries to get up by the urging force (restoring force) of the spring member 5, but the free end side of the operation unit body 41 comes into contact with the finger to which the operation force is applied, and the operation unit 4 Prevents unexpected jumps. In this unlocked state, when the application of the operating force F <b> 2 to the unlocking portion 42 is stopped, the operating portion main body 41 and the unlocking portion 42 are raised by the biasing force (restoring force) of the spring member 5, and the operating portion 4 Returns to the initial position separated from the base 2 (FIG. 5A). Along with this, the pressing portion 3 is also separated from the base main body 21 to be in a state where the binding state is released (non-binding state).

このように、本実施形態に係るファイルＦにおける綴じ具１は、操作部４が、ベース２に対して回動可能に設けられた操作部本体４１と、操作部本体４１の軸心ｍ１と平行な軸心ｍ２を中心に回動し得るように操作部本体４１に片持ち的に支持され、ロック状態を解除して非ロック状態に操作可能なロック解除部４２とを備えたものであり、ロック機構６が、ロック解除部４２に設けた第１係合部４２Ｋと、ベース２に設けられた第２係合部２１Ｋとを備えてなり、ロック解除部４２を押し込む方向のみに与えられた操作力Ｆ２に基づいてロック解除部４２が回動し、それに伴ってロック機構６を構成する第1係合部４２Ｋが回転面内から外れることなく第２係合部に対する相対位置を変えることにより、第１係合部４２Ｋと第２係合部２１Ｋとの係合が解除され非ロック状態になるように構成しているため、ロック解除部４２を押し込むという簡単な操作によってロック状態を解除することが可能であり、しかも、ロック解除操作時に、第１係合部４２Ｋが、回転方向に沿う軌跡を変えることがなく、略直線状の軌跡を辿るため、第１係合部４２Ｋの動作を単純化することができ、確実なロック解除動作を実現し、安定かつ良好な操作感を得ることができる。また、ロック解除部４２が操作部本体４１に対して操作部本体４１の軸心ｍ１と平行な軸心ｍ２を中心に回動可能に設けられているため、ロック操作時に付与する操作力Ｆ１の方向と、ロック解除操作時に付与する操作力Ｆ２の方向が同一となる。このことは、直感的に把握し得るロック解除操作時に付与する操作力の方向が、実際に付与する操作力の方向が同一となることを意味し、使い勝手に優れたものとなる。加えて、ロック機構６が、第１係合部４２Ｋと第２係合部２１Ｋとから構成しているため、操作部４に例えば上下方向のスライド動作を左右方向へのスライド動作に変換するカム等の比較的構造が複雑な変換部を設ける必要がなく、簡素な構造を用いることができ、製作工程の簡素化、コストの削減に資する。 As described above, in the binding tool 1 in the file F according to the present embodiment, the operation unit 4 is provided so as to be rotatable with respect to the base 2, and the axis m1 of the operation unit main body 41 is parallel. A lock release portion 42 that is cantilevered by the operation portion main body 41 so as to be able to rotate around a center axis m2, and that can be unlocked and operated in an unlocked state. The lock mechanism 6 includes a first engagement portion 42K provided in the lock release portion 42 and a second engagement portion 21K provided in the base 2 and is given only in a direction in which the lock release portion 42 is pushed. The lock release portion 42 is rotated based on the operating force F2, and the first engagement portion 42K constituting the lock mechanism 6 is changed along with the second engagement portion without being removed from the rotation surface. The first engaging part 42K and the second engaging part 21K Since it is configured to be unlocked and unlocked, it is possible to release the locked state by a simple operation of pushing in the unlocking portion 42, and at the time of unlocking operation, Since the first engagement portion 42K follows a substantially linear locus without changing the locus along the rotation direction, the operation of the first engagement portion 42K can be simplified, and a reliable unlocking operation is realized. In addition, a stable and good operational feeling can be obtained. Further, since the unlocking portion 42 is provided so as to be rotatable with respect to the operation portion main body 41 about an axis m2 parallel to the axis m1 of the operation portion main body 41, the operation force F1 applied at the time of the lock operation is provided. The direction and the direction of the operating force F2 applied during the unlocking operation are the same. This means that the direction of the operating force applied during the unlocking operation that can be intuitively grasped is the same as the direction of the operating force that is actually applied. In addition, since the lock mechanism 6 is composed of the first engaging portion 42K and the second engaging portion 21K, the operation portion 4 is provided with a cam that converts, for example, a vertical sliding motion into a horizontal sliding motion. It is not necessary to provide a conversion part having a relatively complicated structure, and a simple structure can be used, contributing to simplification of the manufacturing process and cost reduction.

また、操作部本体４１を押し込む方向のみに与えられた操作力Ｆ１に基づいて操作部本体４１が回動し、それに伴って第１係合部４２Ｋが回転面内から外れることなく第２係合部２１Ｋに係合することによりロック状態になるように構成しているため、ロック操作時も第１係合部４２Ｋが回転面内で移動し、第１係合部４２Ｋの安定した動作を実現し、ロック操作がスムーズになり、操作の簡便性を有効に図ることができる。 Further, the operation portion main body 41 rotates based on the operation force F1 applied only in the direction in which the operation portion main body 41 is pushed, and accordingly, the first engagement portion 42K is not disengaged from the inside of the rotation surface. Since it is configured to be locked by engaging with the portion 21K, the first engaging portion 42K moves within the rotation surface even during the locking operation, and the stable operation of the first engaging portion 42K is realized. In addition, the lock operation becomes smooth, and the convenience of the operation can be effectively achieved.

特に、第２係合部２１Ｋを、ベース２に上方に向けて突出するように設けるとともに、第１係合部４２Ｋを、ロック解除部４２のうち、操作部本体４１に支持されている取付端部側に下方に向けて突出するように設けているため、ロック解除部４２の自由端部側を押し込む方向に操作力Ｆ２を付与することにより第１係合部４２Ｋが浮き上がる方向に回動し、第１係合部４２Ｋと第２係合部２１Ｋとの係合を確実に解除することができる。 In particular, the second engagement portion 21K is provided on the base 2 so as to protrude upward, and the first engagement portion 42K is mounted on the operation portion main body 41 of the lock release portion 42. Since it is provided so as to protrude downward on the part side, the first engaging part 42K rotates in the direction of lifting by applying the operating force F2 in the direction of pushing in the free end part side of the unlocking part 42. The engagement between the first engagement portion 42K and the second engagement portion 21K can be reliably released.

操作部４が起き上がる方向に力を付勢するばね部材５の直線軸５３を、ロック解除部４２のうち、操作部本体４１に支持されている取付端部を通過する位置まで延出させているため、ロック解除部４２の一部が直線軸５３に当接又は近接し、操作力が付与されていない状態においてロック解除部４２が下方に不意に沈み込むことを防止することができる。また、ばね部材５の直線軸５３自体がロック機構６の動作に直接関与することがないため、直線軸５３を操作部４の自由端部まで延長させ、この直線軸（付勢手段の一端部）と所定部位に設けた係合部とからロック機構を構成した場合に生じる不具合、つまり、ロット毎に付勢手段の寸法に誤差が生じた場合に、これにより付勢手段の付勢力が異なり、全ての製品に均質な操作感を付与することができないという不具合を解消することができる。 The linear shaft 53 of the spring member 5 that urges the force in the direction in which the operation unit 4 rises is extended to a position in the lock release unit 42 that passes through the attachment end supported by the operation unit main body 41. Therefore, it is possible to prevent the unlocking part 42 from sinking downward unexpectedly in a state where a part of the unlocking part 42 is in contact with or close to the linear shaft 53 and no operating force is applied. Further, since the linear shaft 53 itself of the spring member 5 does not directly participate in the operation of the lock mechanism 6, the linear shaft 53 is extended to the free end portion of the operation portion 4, and this linear shaft (one end portion of the urging means) ) And the engaging portion provided at a predetermined portion, a problem that occurs when the lock mechanism is configured, that is, when an error occurs in the dimension of the biasing means for each lot, the biasing force of the biasing means varies depending on this. Thus, it is possible to solve the problem that it is impossible to give a uniform operational feeling to all products.

加えて、第２係合部２１Ｋが、ベース２の一部を斜め上方に切り起こした切り起し片２１Ｋａと、切り起し片２１Ｋａの先端部を斜め下方に折り曲げてなる折り曲げ片２１Ｋｂとを備えてなり、操作部本体４１を押し込む方向のみに与えられた操作力Ｆ１に基づき、第１係合部４２Ｋが折り曲げ片２１Ｋｂに接触しながら下方にスライド移動し、第１係合部４２Ｋが折り曲げ片２１Ｋｂを乗り越えた際に、第１係合部４２Ｋがばね部材５を利用して第２係合部２１Ｋに係合することにより前記ロック状態になるように構成しているため、第２係合部２１Ｋを極めて簡単に形成することができるとともに、第１係合部４２Ｋが折り曲げ片２１Ｋｂに接触しながらスライド移動するため、折り曲げ片２１Ｋｂが第１係合部４２Ｋの移動を案内するガイド部として機能し、動作の安定性を有効に高めることができる。 In addition, the second engagement portion 21K includes a cut-and-raised piece 21Ka obtained by cutting and raising a part of the base 2 obliquely upward, and a bent piece 21Kb obtained by bending the tip of the cut-and-raised piece 21Ka obliquely downward. The first engaging portion 42K slides downward while contacting the bent piece 21Kb based on the operating force F1 applied only in the pushing direction of the operating portion main body 41, and the first engaging portion 42K is bent. Since the first engagement portion 42K is engaged with the second engagement portion 21K using the spring member 5 when the piece 21Kb is overcome, the second engagement is achieved. The joining portion 21K can be formed very easily, and the first engaging portion 42K slides while contacting the bent piece 21Kb, so that the bent piece 21Kb guides the movement of the first engaging portion 42K. Functions as id portion, it is possible to effectively increase the stability of the operation.

また、操作部本体４１の所定部位に他の領域より低位置となるように窪ませてなる凹段部４１Ｄを設けるとともに、この凹段部４１Ｄの所定部位にロック解除部４２の表出部４２１が表出し得る窓部４１Ｗを設け、この窓部４１Ｗを通じて表出部４２１を表出させるようにロック解除部４２を操作部本体４１に取り付けているため、第１係合部４２Ｋと第２係合部２１Ｋとの係合状態が解除された際、操作力Ｆ２を付与した指が操作部本体４１の一部に当たり、操作部４が不意に跳ね上がることを防止することができ、動作の安全性に優れ、使い勝手に優れたものとなる。また、ロック解除操作時に、ロック解除部４２を下方に沈み込ませると、操作力Ｆ２を付与した指が凹段部４１Ｄに嵌るような構成となり、ロック解除時の操作性をさらに良好なものとすることができる。 In addition, a concave step portion 41D is provided in a predetermined portion of the operation portion main body 41 so as to be lower than other regions, and the exposed portion 421 of the unlocking portion 42 is provided at a predetermined portion of the concave step portion 41D. Is provided, and the unlocking portion 42 is attached to the operation portion main body 41 so that the exposed portion 421 is exposed through the window portion 41W. Therefore, the first engaging portion 42K and the second engaging portion 42 are provided. When the engagement state with the joint portion 21K is released, it is possible to prevent the finger to which the operation force F2 is applied from hitting a part of the operation unit main body 41, and the operation unit 4 from jumping up unexpectedly, and the operation safety Excellent in usability. Further, when the unlocking portion 42 is depressed downward during the unlocking operation, the finger with the operating force F2 is configured to fit into the concave step portion 41D, and the operability during unlocking is further improved. can do.

しかも、窓部４１Ｗが、操作部本体４１の所定部位を切り欠いて形成したものであるため、簡単に窓部４１Ｗを形成することができる。 In addition, since the window portion 41W is formed by cutting out a predetermined portion of the operation portion main body 41, the window portion 41W can be easily formed.

ベース２、押さえ部３及び操作部４が金属製素材からなる折り曲げ成形品であるため、加工容易性に優れ、比較的簡単に製作できるとともに、廃棄時には分別廃棄する必要がない。また、合成樹脂素材からなるものと比較して耐久性にも優れたものとなる。加えて、本実施形態においては、表紙体Ｈが合成樹脂素材からなるファイルＦであるため、廃棄時には表紙体Ｈと綴じ具１とを分解するのみで表紙体Ｈと綴じ具１とを容易に分別することができ好適である。 Since the base 2, the pressing portion 3 and the operation portion 4 are bent molded products made of a metal material, they are excellent in workability, can be manufactured relatively easily, and do not need to be separated and discarded at the time of disposal. Moreover, it will be excellent in durability as compared with a synthetic resin material. In addition, in the present embodiment, since the cover body H is the file F made of a synthetic resin material, the cover body H and the binding tool 1 can be easily separated only by disassembling the cover body H and the binding tool 1 at the time of disposal. It can be separated and is suitable.

なお、以上に説明した第１実施形態において、各部の構成や形状等は本発明の範囲内で任意に変更することが可能である。以下に第２実施形態としてその一例を述べる。

It has a substantially cylindrical engagement shaft X21Kb. Both members X21Ka and X21Kb are integrally fixed by appropriate means with both end portions of the engagement shaft X21Kb protruding outward from the upright pieces X21Kb.

操作部Ｘ４は、ベースＸ２に対して回動可能に設けられた操作部本体Ｘ４１と、この操作部本体Ｘ４１の軸心Ｘｍ１と略平行な軸心Ｘｍ２を中心に回動し得るように操作部本体Ｘ４１に片持ち的に支持され、前記ロック機構Ｘ６のロック状態を解除して非ロック状態に操作可能なロック解除部Ｘ４２とを備えたものである。操作部本体Ｘ４１は、平板部Ｘ４１１と、平板部Ｘ４１１の長手方向に直交する方向の両端から連続して下方に略直角に折り曲げてなる側面部Ｘ４１２とを一体に有する。そして、各側面部Ｘ４１２の自由端部側に、ロック解除部Ｘ４２を取り付ける際に利用される係合孔Ｘ４１ａをそれぞれ設けている。ロック解除部Ｘ４２は、側面視略下向きコ字形状に折り曲げてなる一体成形品であり、操作部本体Ｘ４１の内面側に取り付けられるように各寸法が適宜設定され、主として、平板部Ｘ４２１と、この平板部Ｘ４２１の長手方向に直交する方向の両端から下方に垂下させてなる垂下片Ｘ４２２とを一体に有する。各垂下片Ｘ４２２の取付端部側に、前記操作部本体Ｘ４１の各側面部Ｘ４１２、Ｘ４１３に設けた係合孔Ｘ４１ａに挿入し得る係合突部Ｘ４２ａをそれぞれ設けるとともに、下方に向けて突出するように第１係合部Ｘ４２Ｋを設けている。第１係合部Ｘ４２Ｋは略フック状をなし、前記第２係合部Ｘ２１Ｋの係合軸Ｘ２１Ｋｂに係合し得るように設定してある。操作部本体Ｘ４１及びロック解除部Ｘ４２を一体的に取付けるには、操作部本体Ｘ４１の下方から、ロック解除部Ｘ４２の各垂下片Ｘ４２２に設けた係合突部Ｘ４２ａを、操作部本体Ｘ４１の各側面部Ｘ４１２に設けた係合孔Ｘ４１ａに係合させる。このようにしてロック解除部Ｘ４２が、操作部本体Ｘ４１に片持ち的に支持され、係合突部Ｘ４２２ａと係合孔Ｘ４１ａとの係合部位を軸心Ｘｍ２として操作部本体Ｘ４１に対して回動可能に設けられる。そして、ばね部材５の直線軸５３を、ロック解除部Ｘ４２の下面に当接または近接させることにより、ばね部材５の付勢力によって、ロック解除部Ｘ４２を操作部本体Ｘ４１に対して略水平姿勢となるようにしている。 The operation unit X4 is configured to be rotatable about an operation unit main body X41 provided to be rotatable with respect to the base X2 and an axis Xm2 substantially parallel to the axis Xm1 of the operation unit main body X41. A lock release portion X42 that is supported in a cantilevered manner by the main body X41 and can be operated in an unlocked state by releasing the lock state of the lock mechanism X6. The operation portion main body X41 integrally includes a flat plate portion X411 and a side surface portion X412 which is continuously bent from both ends in a direction orthogonal to the longitudinal direction of the flat plate portion X411 and bent downward at a substantially right angle. And the engagement hole X41a utilized when attaching the lock release part X42 is provided in the free end part side of each side part X412, respectively. The unlocking part X42 is an integrally molded product that is bent in a substantially downward U shape when viewed from the side, and each dimension is appropriately set so as to be attached to the inner surface side of the operation part main body X41. A hanging piece X422 is integrally formed by hanging downward from both ends in a direction orthogonal to the longitudinal direction of the flat plate portion X421. Engagement protrusions X42a that can be inserted into engagement holes X41a provided in the side surface parts X412 and X413 of the operation part main body X41 are provided on the attachment end part side of each hanging piece X422, and project downward. Thus, the first engagement portion X42K is provided. The first engagement portion X42K has a substantially hook shape and is set so as to be able to engage with the engagement shaft X21Kb of the second engagement portion X21K. In order to integrally attach the operation portion main body X41 and the lock release portion X42, the engaging protrusions X42a provided on the respective hanging pieces X422 of the lock release portion X42 are respectively connected to the operation portion main body X41 from below the operation portion main body X41. It is made to engage with the engagement hole X41a provided in the side part X412. In this way, the unlocking portion X42 is cantilevered by the operation portion main body X41, and the engagement portion between the engagement protrusion X422a and the engagement hole X41a is set as the axis Xm2 with respect to the operation portion main body X41. It is provided to be movable. Then, by bringing the linear shaft 53 of the spring member 5 into contact with or close to the lower surface of the unlocking portion X42, the unlocking portion X42 is brought into a substantially horizontal posture with respect to the operation portion main body X41 by the biasing force of the spring member 5. It is trying to become.

ロック機構Ｘ６は、前記ロック解除部Ｘ４２に設けた第１係合部Ｘ４２Ｋと、ベースＸ２のベース本体Ｘ２１に形成した第２係合部Ｘ２１Ｋとからなるものであり、後述する所定の操作力により、第１係合部Ｘ４２Ｋと第２係合部Ｘ２１Ｋとを相互に係わり合わせたロック状態と、第１係合部Ｘ４２ＫとＸ第２係合部２１Ｋとの係合状態を解除した非ロック状態とに操作可能に構成されたものである。 The lock mechanism X6 includes a first engagement portion X42K provided in the lock release portion X42 and a second engagement portion X21K formed in the base body X21 of the base X2, and by a predetermined operation force described later. The locked state in which the first engaging portion X42K and the second engaging portion X21K are engaged with each other, and the unlocked state in which the engaging state between the first engaging portion X42K and the X second engaging portion 21K is released. And is configured to be operable.

そして、各部を組み立ててなる綴じ具Ｘ１において、操作部本体Ｘ４１は固定ピンＮを軸心ｍ１として回転可能に設けられ、この軸心Ｘｍ１と、前述したロック解除部４２の軸心Ｘｍ２とは略平行をなすように設定してある。 And in the binding tool X1 which assembles each part, the operation part main body X41 is provided rotatably with the fixing pin N as an axis m1, and the axis Xm1 and the axis Xm2 of the lock release part 42 described above are approximately. It is set to be parallel.

このような構成を有する綴じ具Ｘ１の操作方法及び作用を、図１０乃び図１１等を参照して説明する。なお、図１０及び図１１は、図７におけるＢ−Ｂ線断面を一部省略して示す作用説明図である。 The operation method and operation of the binding tool X1 having such a configuration will be described with reference to FIGS. 10 and 11 are operation explanatory views showing a part of the cross section taken along the line BB in FIG.

先ず、操作部Ｘ４が起き上がっている状態（図１０（ａ））において、使用者が操作部本体Ｘ４１の自由端部側に設けた突部Ｘ４１ｂからなる押下指示部を押圧することによって、操作部Ｘ４をベース本体Ｘ２１側に押し込む方向に操作力Ｆ１が付与される。この操作力Ｆ１に基づいて、操作部Ｘ４がベース本体Ｘ２１に対して略水平姿勢となる方向に回転し、経過的にロック解除部Ｘ４２の第１係合部Ｘ４２Ｋが、ベースＸ２の第２係合部Ｘ２１Ｋに当接する（同図（ｂ））。具体的には、第１係合部Ｘ４２Ｋが、第２係合部Ｘ２１Ｋの係合軸Ｘ２１Ｋｂに当接する。引き続き、前記操作力Ｆ１により、第１係合部Ｘ４２Ｋが、係合軸Ｘ２１Ｋｂに接触しながら軸心Ｘｍ１に略直交する平面、すなわち回転面内から外れることなく係合軸Ｘ２１Ｋｂに倣ってスライド移動し、第１係合部Ｘ４２Ｋが係合軸Ｘ２１Ｋｂを乗り越えたときに、第１係合部Ｘ４２Ｋが前記ばね部材５の付勢力を利用して係合軸Ｘ２１Ｋｂに係合する（図１１（ｃ））。以上の操作により、操作部Ｘ４の上方への回転移動が規制されるロック状態となる。 First, in a state where the operation unit X4 is raised (FIG. 10A), the user presses the pressing instruction unit including the protrusion X41b provided on the free end side of the operation unit main body X41. An operating force F1 is applied in a direction in which X4 is pushed into the base body X21 side. Based on this operating force F1, the operating portion X4 rotates in a direction that assumes a substantially horizontal posture with respect to the base body X21, and the first engaging portion X42K of the unlocking portion X42 gradually passes through the second engagement of the base X2. It abuts on the joint portion X21K (FIG. 5B). Specifically, the first engaging portion X42K abuts on the engaging shaft X21Kb of the second engaging portion X21K. Subsequently, the first engagement portion X42K slides along the engagement axis X21Kb without coming out of the plane substantially perpendicular to the axis Xm1 while contacting the engagement axis X21Kb, that is, within the rotation plane, by the operation force F1. When the first engagement portion X42K gets over the engagement shaft X21Kb, the first engagement portion X42K uses the biasing force of the spring member 5 to engage with the engagement shaft X21Kb (FIG. 11 (c). )). With the above operation, a locked state is established in which the rotational movement of the operation unit X4 is restricted.

また、ロック状態を解除（非ロック状態に）するには、ロック解除部Ｘ４２の自由端部側に設けた突部Ｘ４２ｂからなる押下指示部を上方から押圧することによって、ロック解除部Ｘ４２をベース本体Ｘ２１側に押し込む方向に操作力Ｆ２が付与される。この操作力Ｆ２に基づいて、ロック解除部Ｘ４２が操作部本体Ｘ４１の軸心Ｘｍ１と平行な軸心Ｘｍ２を中心として回転動作を行い、自由端部側が下方に向かって沈み込む方向に回動するとともに、第１係合部Ｘ４２Ｋが上方に向かって浮き上がる方向に回動する。これにより、第１係合部Ｘ４２Ｋが、回転面内から外れることなく第２係合部Ｘ２１Ｋから離反する方向に移動し、第１係合部Ｘ４２Ｋと係合軸Ｘ２１Ｋｂとの係合状態が解除され、非ロック状態となる（同図（ｄ））。そして、この非ロック状態において、ロック解除部Ｘ４２への操作力Ｆ２の付与を停止した場合、操作部本体Ｘ４１及びロック解除部Ｘ４２がばね部材５の付勢力（復元力）によって起き上がり、操作部Ｘ４がベースＸ２から離間した初期の位置に復帰する（図１０（ａ））。 Further, in order to release the locked state (into the unlocked state), the lock releasing portion X42 is made to be the base by pressing the pressing instruction portion including the protrusion X42b provided on the free end side of the unlocking portion X42 from above. An operating force F2 is applied in the direction of pushing in the main body X21. Based on this operating force F2, the unlocking portion X42 rotates around an axis Xm2 parallel to the axis Xm1 of the operating portion main body X41, and the free end side rotates in a direction that sinks downward. At the same time, the first engaging portion X42K rotates in a direction to rise upward. As a result, the first engagement portion X42K moves in a direction away from the second engagement portion X21K without being disengaged from the rotation surface, and the engagement state between the first engagement portion X42K and the engagement shaft X21Kb is released. Then, the locked state is established ((d) in the figure). In this unlocked state, when the application of the operating force F2 to the unlocking portion X42 is stopped, the operating portion main body X41 and the unlocking portion X42 are raised by the biasing force (restoring force) of the spring member 5, and the operating portion X4. Returns to the initial position separated from the base X2 (FIG. 10A).

このような構成であっても、前記実施形態と同様に、従来にない使い勝手の優れたものとすることができるとともに、第２実施形態特有の効果としては、操作部本体Ｘ４１の自由端部にロック解除部Ｘ４２を取り付けているため、ロック解除部Ｘ４２の一端部（先端部）が完全にフリーな状態となり、ロック解除部Ｘ４２を押し込む方向のみに操作力Ｆ２を付与した場合に、操作力Ｆ２を付与した指が操作部本体Ｘ４１に干渉することがなく、ロック解除時の操作性を良好なものとすることができる点が挙げられる。 Even with such a configuration, as in the above embodiment, it is possible to make it excellent in ease of use, which is not conventional, and as an effect peculiar to the second embodiment, the free end portion of the operation unit main body X41 Since the unlocking portion X42 is attached, one end (tip) of the unlocking portion X42 is completely free, and the operating force F2 is applied only when the operating force F2 is applied only in the direction in which the unlocking portion X42 is pushed. It is possible to improve the operability at the time of unlocking without interfering with the operation portion main body X41.

なお、本発明は、以上に詳述した各実施形態に限られるものではない。 The present invention is not limited to the embodiments described in detail above.

例えば、ロック機構は、相互に係合する２つの部材から構成されるものであればよく、例えば、係合爪と係合孔とから構成されるものや、係合爪と係合軸とから構成されるものであっても構わない。 For example, the lock mechanism only needs to be composed of two members that are engaged with each other. For example, the lock mechanism is composed of an engagement claw and an engagement hole, or an engagement claw and an engagement shaft. It may be configured.

また、綴じ具を、表紙体の左右方向に沿って設けてもよく、また図示した表紙体以外の表紙体に適用しても構わない。 Further, the binding tool may be provided along the left-right direction of the cover body, or may be applied to a cover body other than the illustrated cover body.
