Description

本発明は、綴じ具及びファイルに係り、更に詳しくは、ベースの通路を通過するように綴じ足を位置させて当該綴じ足の倒伏と押さえ付けを行うことで用紙等の綴じ込みを行う一方、前記通路を開放することで綴じ込みを解除することのできる綴じ具及びファイルに関する。   The present invention relates to a binding tool and a file. More specifically, the binding foot is positioned so as to pass through the passage of the base and the binding foot is laid down and pressed down to bind the paper or the like. The present invention relates to a binding tool and a file that can release binding by opening a passage.

従来より、フラットファイルやレターファイル等に用いられる綴じ具としては、板状に延びる細長いベースと、このベースの長手方向二箇所に設けられた穴からなる綴じ足の通路と、ベース上面側に設けられて通路を開放する位置と遮断する位置との間で移動可能なスライダとを備えて構成されている。
しかしながら、このような綴じ具は、スライダをベースに沿って横方向にそれぞれ移動させなければならないため、操作の簡便性が得られず、また、スライダの操作方向とベースの着脱操作方向とが異なって、操作の迅速性に欠けることとなる。 Conventionally, as a binding tool used for a flat file, a letter file, and the like, a long and narrow base extending in a plate shape, a path of a binding foot formed of holes provided in two longitudinal directions of the base, and a base upper surface side are provided. And a slider that is movable between a position for opening the passage and a position for blocking the passage.
However, such a binding tool cannot move easily because the slider must be moved laterally along the base, and the operation direction of the slider is different from the direction of attaching / detaching the base. Therefore, the speed of operation is lacking.

そこで、例えば、特許文献１に開示されるように、複数の綴じ足をそれぞれ通過させる複数の通路を備えたベースと、当該ベースに沿って移動可能に設けられた複数の移動部材と、これら移動部材を同時に操作可能な操作部とを備え、当該操作部を所定操作することで、各移動部材が通路を開放する位置と遮断する位置との間で移動可能に設けられた綴じ具が提案されている。   Therefore, for example, as disclosed in Patent Document 1, a base including a plurality of passages through which a plurality of binding feet pass, a plurality of moving members provided movably along the base, and these movements And a binding tool that is provided so that each moving member can move between a position where the moving member opens the passage and a position where the moving member is blocked by operating the operating portion with a predetermined operation. ing.

しかしながら、特許文献１に開示された綴じ具にあっては、各移動部材を同期移動させるための複雑な機構が必要となり、部品点数が増加する、という不都合がある。
また、操作部を操作して綴じ込みを解除する位置としたときに、操作部が山形に屈曲した形状となり、操作部をベース側に押圧操作する際に、その操作力をベースに対して直交する方向に付与し難くなる傾向がある。
しかも、綴じ足を倒伏させる際の初期の抵抗が強く、スムースな操作感も得られない、という不都合もある。 However, the binding tool disclosed in Patent Document 1 requires a complicated mechanism for synchronously moving the moving members, which increases the number of parts.
In addition, when the operation unit is operated to release the binding, the operation unit is bent in a mountain shape, and when the operation unit is pressed to the base side, the operation force is orthogonal to the base. There is a tendency to become difficult to give in the direction.
In addition, there is a disadvantage that the initial resistance when the binding leg is laid down is strong and a smooth operation feeling cannot be obtained.

［発明の目的］
本発明は、このような不都合に着目して案出されたものであり、その目的は、部品点数を削減するとともに、押さえ部材が綴じ込みを解除する位置にあるときに、綴じ足の通路を常に開放した状態に保つことのできる綴じ具及びファイルを提供することにある。 [Object of invention]

更に、本発明の目的は、綴じ足を倒伏動作させる際の初期の抵抗力を軽減し、当該綴じ足をスムースに倒伏して綴じ込み位置に設定することのできる綴じ具及びファイルを提供することにある。   Furthermore, an object of the present invention is to provide a binding tool and a file that can reduce the initial resistance force when the binding foot is tilted, and can smoothly set the binding foot to the binding position. is there.

前記目的を達成するため、本発明は、複数の綴じ足をそれぞれ通過させる複数の通路を備えるとともに、長手方向に延びる形状を備えたベースと、このベース上に位置するとともに、前記各通路を同時に遮断して綴じ足を倒伏させる綴じ込み位置と、各通路を同時に開放して綴じ込みを解除する位置との間で変位可能に設けられた押さえ部材とを含む綴じ具において、
前記ベースは、長手方向両側に設けられた案内部と、これら案内部の内側位置で前記押さえ部材に相対変位可能に連結される一対の連結部材とを備え、
前記押さえ部材は、操作部と、この操作部に対して屈曲可能に連設されるとともに前記通路の遮断と開放とを行う一対の押さえ板と、当該押さえ板に設けられて前記案内部にそれぞれ移動可能に支持される取付部とを備え、
前記取付部を案内部に支持させた状態で連結部材を介してベースと押さえ部材とを連結することでこれらベースと押さえ部材とが組み合わせ可能とされ、
前記操作部をベースに対して離間接近する方向に操作力を付与したときに、前記押さえ板の外側端部が前記案内部に沿って移動して前記綴じ込みと解除とを行う、という構成を採っている。 In order to achieve the above object, the present invention includes a plurality of passages through which a plurality of binding feet respectively pass, a base having a shape extending in a longitudinal direction, and a base positioned on the base, and the passages are simultaneously disposed. In a binding tool including a binding position that shuts down and lowers the binding foot, and a pressing member that is displaceable between a position that simultaneously opens each passage and releases binding,
The base includes a guide portion provided on both sides in the longitudinal direction, and a pair of connecting members connected to the pressing member at a position inside the guide portion so as to be relatively displaceable.
The pressing member is connected to the operating portion, a pair of pressing plates that are connected to the operating portion so as to be bendable and that blocks and opens the passage, and the pressing plate is provided on the pressing plate. A mounting portion supported movably,
The base and the pressing member can be combined by connecting the base and the pressing member via the connecting member in a state where the mounting portion is supported by the guide portion,
When an operation force is applied in a direction in which the operation unit moves away from the base, the outer end portion of the pressing plate moves along the guide unit to perform the binding and release. ing.

本発明において、前記一対の連結部材は、前記押さえ部材が変位するときに対称的に変位するように設けられている。   In the present invention, the pair of connecting members are provided so as to be displaced symmetrically when the pressing member is displaced.

また、前記連結部材は、前記押さえ部材が前記綴じ込みを解除した位置にあるときに、前記ベースと押さえ部材との相対位置を保持して通路の開放状態を維持する、という構成を採っている。   Further, the connecting member has a configuration in which when the pressing member is in the position where the binding is released, the relative position between the base and the pressing member is maintained and the open state of the passage is maintained.

更に、前記連結部材の中間と前記ベースとの間に、当該連結部材の変位に追従して変位可能な補助部材が設けられ、当該補助部材は、前記押さえ部材が前記綴じ込みを解除したときに、前記ベースと押さえ部材との相対位置を補助的に保持する構成を採ることが好ましい。   Furthermore, an auxiliary member that can be displaced following the displacement of the connecting member is provided between the middle of the connecting member and the base, and the auxiliary member is released when the pressing member releases the binding. It is preferable to adopt a configuration in which the relative position between the base and the pressing member is supplementarily held.

更に、前記押さえ部材は、前記操作部が水平位置を保った状態で変位可能に設けられる、という構成を採るとよい。   Further, the pressing member may be configured to be displaceable in a state in which the operation unit maintains a horizontal position.

また、前記押さえ板の外側端部は、前記綴じ足に初期の倒伏力を付与する接触部位として作用するとともに、前記取付部よりも上位に位置するように構成されている。   Moreover, the outer side edge part of the said press board acts as a contact part which provides the initial lying force to the said binding leg, and is comprised so that it may be located higher than the said attachment part.

更に、本発明に係るファイルは、前述した綴じ具と、当該綴じ具が取り付けられる表紙体とからなり、前記綴じ足は、その基部が表紙体に支持される、という構成を採っている。   Furthermore, the file according to the present invention includes the above-described binding tool and a cover body to which the binding tool is attached, and the binding foot has a configuration in which a base portion is supported by the cover body.

In addition, it is possible to simultaneously perform binding and release operations on each binding foot simply by applying an operating force to the operation unit, and there is no need to provide additional parts such as a pinion.

また、連結部材が対称的に変位する構成により、操作部に操作力を付与したときに、押さえ部材の両側に操作力を等しく及ばせることができる。   Further, due to the configuration in which the connecting member is displaced symmetrically, the operating force can be equally applied to both sides of the pressing member when the operating force is applied to the operating portion.

更に、前記ベースに対して連結部材が綴じ込みを解除した状態を維持するように設けられているため、用紙を綴じ込むときに、通路が開放した状態を常に保っていることによって綴じ込み操作を迅速に行うことができる。   Further, since the connecting member is provided so as to maintain the state in which the binding is released with respect to the base, the binding operation can be quickly performed by always maintaining the state in which the passage is opened when binding the paper. It can be carried out.

また、補助部材を設けた構成によれば、押さえ部材が綴じ込みを解除した状態をより確実に保つことができる。   Moreover, according to the structure which provided the auxiliary member, the state which the press member released the binding can be maintained more reliably.

更に、押さえ部材の操作部が水平位置を保った状態で押さえ部材が変位可能であれば、操作力を付与する際に指先を痛めてしまうような不都合を回避することができる。   Further, if the pressing member can be displaced while the operation portion of the pressing member is kept in a horizontal position, it is possible to avoid the inconvenience that the fingertip is damaged when the operating force is applied.

また、前記板状体の外側端部を取付部よりも上位とすることで、綴じ足を曲げるときの力が綴じ足の基部から離れた上方に加えられるように設定でき、綴じ足を折り曲げて倒伏させる動作の初期段階における抵抗を緩和することができる。従って、従来品に比べて小さい操作力で綴じ足を折り曲げて倒伏させることができる。   In addition, by setting the outer end of the plate-like body higher than the attachment portion, it can be set so that the force when bending the binding foot is applied upward away from the base of the binding foot, and the binding foot is bent. The resistance in the initial stage of the operation of lying down can be relaxed. Therefore, the binding leg can be bent and laid down with a smaller operating force than the conventional product.

綴じ具１０を組み立てるときは、ベース１５の上面側に押さえ部材１６を位置させた状態で、当該押さえ部材１６の長手方向両側に設けられた各一対の突起６０をベース１５の案内部２０に位置させる。次いで、押さえ部材１６の操作部５０を摘んでベース１５との間に空間を形成しておき、連結部材２５の凸部３０を押さえ部材１６の軸受部６２に嵌合させる。これによって、ベース１５と押さえ部材１６との組み合わせを完了することができる。   When assembling the binding tool 10, the pair of protrusions 60 provided on both sides in the longitudinal direction of the pressing member 16 are positioned on the guide portion 20 of the base 15 with the pressing member 16 positioned on the upper surface side of the base 15. Let Next, the operating portion 50 of the pressing member 16 is picked so that a space is formed between the pressing member 16 and the base 15, and the convex portion 30 of the connecting member 25 is fitted to the bearing portion 62 of the pressing member 16. Thereby, the combination of the base 15 and the pressing member 16 can be completed.

次に、綴じ具１０の使用方法について、図１１及び図１２をも参照して説明する。   Next, the usage method of the binding tool 10 is demonstrated with reference also to FIG.11 and FIG.12.

前記綴じ具１０を用いて用紙Ｐを綴じ込む場合には、押さえ部材１６の操作部５０がベース１５に対して離間した位置に保っておくことにより行われる（図２参照）。
すなわち、操作部５０の側壁５５を指先で摘んで、ベース１５の面に対して直交する上方に力を加えることで、両側に設けられた突起６０が案内部２０の内側にそれぞれ移動する。同時に、連結部材２５は、その先端側の凸部３０が押さえ部材１６側の軸受部６２に回転可能に支持されているため、ヒンジ部２９を介して凸部３０側が上方に回転して変位する。つまり、押さえ部材１６と連結部材２５は、パンタグラフに類似した状態で変位する。連結部材２５が変位を開始してから図２に示される位置（綴じ込み解除位置）に至る中間段階では、前記凸部３０は、軸受部６２に支持されていることとの関係で、連結部材２５が無負荷状態の初期形状を保有していると仮定したときの本来通過すべき位置よりも内側にシフトさせられるように屈曲する。このとき、連結部材２５に連なる補助部材４０は、無負荷状態で変形がないとした場合の初期形状に対し、基部片４２及び連結片４３間の屈曲角度を小さくする方向に一時的に折れ曲がりつつ上方に変位する。 When the paper P is bound using the binding tool 10, the operation unit 50 of the pressing member 16 is kept at a position separated from the base 15 (see FIG. 2).
That is, the side wall 55 of the operation unit 50 is picked with a fingertip, and a force is applied in an upward direction perpendicular to the surface of the base 15, whereby the protrusions 60 provided on both sides move to the inside of the guide unit 20. At the same time, the convex portion 30 on the distal end side of the connecting member 25 is rotatably supported by the bearing portion 62 on the pressing member 16 side, so that the convex portion 30 side is rotated and displaced upward via the hinge portion 29. . That is, the pressing member 16 and the connecting member 25 are displaced in a state similar to a pantograph. In the intermediate stage from the start of displacement of the connecting member 25 to the position shown in FIG. 2 (binding release position), the protrusion 30 is connected to the bearing portion 62 in relation to the connecting member 25. Is bent so as to be shifted inward from the position that should originally pass when assuming that it has an initial shape in an unloaded state. At this time, the auxiliary member 40 connected to the connecting member 25 is temporarily bent in the direction of reducing the bending angle between the base piece 42 and the connecting piece 43 with respect to the initial shape when there is no deformation in the unloaded state. Displace upward.

操作部５０がベース１５に対して最大に離間したとき（図２の綴じ込み解除位置にあるとき）には、連結部材２５が前記屈曲の程度を弱めつつも依然として屈曲変形した状態となり、当該屈曲変形がないとした場合の凸部３０の本来の位置よりも内方にシフトさせられた位置をとり、元の位置に戻ろうとする反発力が押さえ板５３を斜め外側上方に付与するように作用する。このとき、補助部材４０は、初期形状に対して屈曲している形状を保ち、前記連結片４３と連結部材２５との連設部位に対し、斜め内側上方に力を付与し、連結部材２５を下方から支えて連結部材２５が押さえ部材１６の前記綴じ込み解除位置を保つ作用をバックアップする。これにより、突起６０が案内部２０で静止した位置を保って通路１４が常に開放した状態に保たれる。   When the operation unit 50 is separated to the maximum with respect to the base 15 (when in the binding release position in FIG. 2), the connecting member 25 is still bent and deformed while the degree of bending is weakened. The position of the convex portion 30 that is shifted inward from the original position when there is no action is taken, and the repulsive force that tries to return to the original position acts to apply the pressing plate 53 obliquely outward and upward. . At this time, the auxiliary member 40 maintains a bent shape with respect to the initial shape, and applies a force obliquely upward to the connecting portion between the connecting piece 43 and the connecting member 25, Supporting from below, the connecting member 25 backs up the action of maintaining the binding release position of the pressing member 16. Thereby, the position where the projection 60 is stationary at the guide portion 20 is maintained, and the passage 14 is always kept open.

このようにして通路１４が開放した状態、つまり、綴じ足１３の綴じ込みを解除した状態で、ファイル内面側の折り込み部分１１を受け面として用紙Ｐの綴じ穴に綴じ足１３を挿入した後、この綴じ足１３が通路１４内に位置するようにベース１５を横方向から位置させて、当該ベース１５を用紙Ｐ上に位置させる（図２参照）。   After inserting the binding foot 13 into the binding hole of the sheet P with the folding portion 11 on the file inner surface side as the receiving surface in a state where the passage 14 is opened in this way, that is, in a state where the binding of the binding foot 13 is released, The base 15 is positioned from the lateral direction so that the binding foot 13 is positioned in the passage 14, and the base 15 is positioned on the paper P (see FIG. 2).

次いで、図１１に示されるように、操作部５０の上面に指先をあてがい、ベース１５に向かう操作力を付与する。すると、押さえ部材１６の位置を保持していた連結部材２５及び補助部材４０が回転変位し、押さえ部材１６は、両端側の突起６０が案内部２０に沿ってそれぞれ外側に移動し、平面視の長さを長くするように変位する。この際、押さえ板５３の外側端部５３Ａが綴じ足１３に当接して当該綴じ足１３を外側に倒伏させる方向に力を付与することとなる。本実施形態においては、突起６０に対して、前述した寸法Ｌ分上位に突起６０が位置するように設定されているため、綴じ足１３が折れ曲がろうとする部位が案内部２０の上面よりも高くなり、折り曲げ抵抗を緩和することができる。   Next, as shown in FIG. 11, a fingertip is applied to the upper surface of the operation unit 50 to apply an operation force toward the base 15. Then, the connecting member 25 and the auxiliary member 40 that have held the position of the pressing member 16 are rotationally displaced. In the pressing member 16, the protrusions 60 on both ends move outward along the guide portions 20, respectively. Displace to increase the length. At this time, the outer end 53 </ b> A of the pressing plate 53 comes into contact with the binding foot 13, and a force is applied in a direction in which the binding foot 13 is laid down outward. In the present embodiment, since the protrusion 60 is set so as to be positioned higher than the protrusion 60 by the dimension L described above, the portion where the binding foot 13 is about to be bent is higher than the upper surface of the guide portion 20. This increases the bending resistance.

綴じ足１３が折れ曲がりを開始した状態で更に操作部５０に下向きの力を付与し続けると（図１２参照）、前記外側端部５３Ａが綴じ足１３の上面を滑りながら当該綴じ足１３を更に倒伏させ、この一方で、連結部材２５及び補助部材４０がベース１５の穴３２に次第に入りこみ、操作部５０がベース１５の中央部上面に突き当たったときに、押さえ部材１６とベース１５とが図示しない公知のストッパを介して互いに係り合って綴じ込み位置が保たれる。   If the downward force is continuously applied to the operation unit 50 in a state where the binding foot 13 starts to bend (see FIG. 12), the outer end 53A slides on the upper surface of the binding foot 13 and further collapses the binding foot 13. On the other hand, when the connecting member 25 and the auxiliary member 40 gradually enter the hole 32 of the base 15 and the operation unit 50 hits the upper surface of the central portion of the base 15, the pressing member 16 and the base 15 are not shown. The binding position is maintained by engaging with each other via the stopper.

従って、このような実施例によれば、少ない部品点数で、しかも、ベース１５に対して押さえ部材１６を離間接近させる操作で当該押さえ部材１６の両側を同時に移動させて用紙Ｐの綴じ込みと、その解除を行うことが可能な綴じ具を提供することができる。   Therefore, according to such an embodiment, the sheet P is bound by moving the both sides of the pressing member 16 at the same time by the operation of moving the pressing member 16 away from the base 15 with a small number of parts. A binding tool that can be released can be provided.
