本発明の一実施形態を、図面を参照して説明する。図１ないし図３、図６ないし図８に示すように、本実施形態のファイルは、表表紙１１、背表紙１２及び裏表紙１３を有する表紙体１に、書類その他の紙葉類を収納することのできる複数のポケット３、並びに紙葉類を綴じ止めることのできる綴じ具２を取り付けてなるものである。 An embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1 to FIG. 3 and FIG. 6 to FIG. 8, the file of this embodiment stores documents and other paper sheets in a cover body 1 having a front cover 11, a back cover 12 and a back cover 13. A plurality of pockets 3 capable of binding, and a binding tool 2 capable of binding paper sheets are attached.

図４に示すように、表紙体１は、例えば樹脂製の一体成形品であり、全体として略方形状をなす板状体である。表表紙１１と背表紙１２との間、背表紙１２と裏表紙１３との間には、それぞれヒンジ１４を設けている。ヒンジ１４は、表紙高さ方向、即ちファイルを立てたときの表表紙１１、背表紙１２及び裏表紙１３の上下方向に沿って延伸する凹溝である。表紙体１における、ヒンジ１４が存在する部分の厚みは、それ以外の部分（表表紙１１、背表紙１２及び裏表紙１３）の厚みよりも薄肉となる。このヒンジ１４により、表表紙１１及び裏表紙１３はそれぞれ、背表紙１２に対して、表紙高さ方向に沿って伸びる軸回りに回動することが可能となる。表表紙１１と背表紙１２との間に介在するヒンジ１４と、背表紙１２と裏表紙１３との間に介在するヒンジ１４とは、互いに略平行である。 As shown in FIG. 4, the cover body 1 is, for example, an integrally molded product made of resin, and is a plate-like body having a substantially square shape as a whole. Hinges 14 are provided between the front cover 11 and the back cover 12, and between the back cover 12 and the back cover 13, respectively. The hinge 14 is a concave groove extending along the front cover height direction, that is, the vertical direction of the front cover 11, the back cover 12, and the back cover 13 when the file is erected. The thickness of the portion of the cover body 1 where the hinges 14 are present is thinner than the thickness of the other portions (the front cover 11, the back cover 12, and the back cover 13). The hinge 14 allows the front cover 11 and the back cover 13 to rotate around an axis extending along the cover height direction with respect to the spine cover 12, respectively. The hinge 14 interposed between the front cover 11 and the back cover 12 and the hinge 14 interposed between the back cover 12 and the back cover 13 are substantially parallel to each other.

表紙体１における、背表紙１２と裏表紙１３との間に介在するヒンジ１４に跨る箇所、または当該ヒンジ１４に隣接する箇所には、綴じ具２を通過させるための貫通孔１５を形成している。貫通孔１５は、表紙体１の表紙高さ方向の中間部にあって、裏表紙１３側のヒンジ１４に対して略平行に伸びる、手指を挿入し得ない程度の（幅が４ｍｍないし５ｍｍの）幅狭なスリット状をなす。本実施形態では、このスリット１５の大部分が背表紙１２における裏表紙１３に隣接する部位に所在し、極僅かながらヒンジ１４を越えて裏表紙１３まで拡張している。 A through-hole 15 for allowing the binding tool 2 to pass is formed in a place over the hinge 14 interposed between the spine cover 12 and the back cover 13 in the cover body 1 or a position adjacent to the hinge 14. Yes. The through hole 15 is in the middle of the cover body 1 in the cover height direction, and extends substantially parallel to the hinge 14 on the back cover 13 side so that a finger cannot be inserted (the width is 4 mm to 5 mm). ) Form a narrow slit. In the present embodiment, most of the slit 15 is located in a portion of the back cover 12 adjacent to the back cover 13 and extends slightly beyond the hinge 14 to the back cover 13.

加えて、表紙体１の裏表紙１３の内側縁部には、綴じ具２のベース部２１から突出する筒状部２５１を挿通するための挿通孔１６を穿ってある。後述するように、筒状部２５１は、綴じ具２の押さえ部２３から突出する軸部２５２とともに、紙葉類を綴じ止めるための綴じ桿２５を構成する。 In addition, an insertion hole 16 for inserting the cylindrical portion 251 protruding from the base portion 21 of the binding tool 2 is formed in the inner edge portion of the back cover 13 of the cover body 1. As will be described later, the cylindrical portion 251 and the shaft portion 252 protruding from the pressing portion 23 of the binding tool 2 constitute a binding rod 25 for binding paper sheets.

背表紙１２と裏表紙１３との間に介在するヒンジ１４の溝の形状及び深さは全体的に略均一であり、表紙体１における当該ヒンジ１４が存在する部位の厚みは同ヒンジ１４の溝の全長に亘って略均等である。 The shape and depth of the groove of the hinge 14 interposed between the back cover 12 and the back cover 13 are substantially uniform as a whole, and the thickness of the portion of the cover 1 where the hinge 14 is present is the groove of the hinge 14. Is substantially uniform over the entire length.

これに対し、表表紙１１と背表紙１２との間に介在するヒンジ１４の溝の形状は全体的に略均一ではなく、表紙体１における当該ヒンジ１４が存在する部位の厚みは同ヒンジ１４の溝の全長に亘って略均等ではない。本実施形態では、表表紙１１と背表紙１２との間に介在するヒンジ１４の一部に、表紙体１の厚みをより薄くする薄肉部１４１を設けている。言うまでもなく、表紙体１の厚みをより薄くすることは、表紙体１（のヒンジ１４）の曲げ剛性をより低下させることを意味する。なお、同ヒンジ１４における薄肉部１４１以外の部分の溝の形状及び深さは、背表紙１２と裏表紙１３との間に介在するヒンジ１４の溝の形状及び深さに略等しい。 On the other hand, the shape of the groove of the hinge 14 interposed between the front cover 11 and the back cover 12 is not substantially uniform as a whole, and the thickness of the portion of the cover 1 where the hinge 14 is present is the same as that of the hinge 14. It is not substantially uniform over the entire length of the groove. In the present embodiment, a thin portion 141 for reducing the thickness of the cover body 1 is provided in a part of the hinge 14 interposed between the cover cover 11 and the spine cover 12. Needless to say, reducing the thickness of the cover body 1 means lowering the bending rigidity of the cover body 1 (the hinge 14). It should be noted that the shape and depth of the groove of the hinge 14 other than the thin wall portion 141 are substantially equal to the shape and depth of the groove of the hinge 14 interposed between the back cover 12 and the back cover 13.

薄肉部１４１は、例えば、図５（ａ）に示すように、表紙体１の表裏即ち外表面側及び内向面側の双方に凹溝を形成することにより実現する。ヒンジ１４の薄肉部１４１以外の部分の凹溝は、表紙体１の内向面側にのみ、または外表面側にのみ形成する。あるいは、図５（ｂ）に示すように、ヒンジ１４の薄肉部１４１の溝の深さを、薄肉部１４１以外の部分の溝の深さよりも深くしても構わない。 For example, as shown in FIG. 5A, the thin portion 141 is realized by forming concave grooves on the front and back of the cover body 1, that is, on both the outer surface side and the inward surface side. The concave grooves of the hinge 14 other than the thin portion 141 are formed only on the inward surface side of the cover 1 or only on the outer surface side. Or as shown in FIG.5 (b), you may make the depth of the groove | channel of the thin part 141 of the hinge 14 deeper than the depth of the groove | channel of parts other than the thin part 141. FIG.

本実施形態では、ちょうど上記の貫通孔１５に相対するように、表表紙１１側のヒンジ１４の表紙高さ方向の中間部を薄肉部１４１としている。貫通孔１５の一端（表紙高さ方向に沿った上端）と薄肉部１４１の一端（上端）とを結ぶ線分は、ヒンジ１４の延伸方向である表紙高さ方向に対して略直交する。同様に、貫通孔１５の他端（表紙高さ方向に沿った下端）と薄肉部１４１の他端（下端）とを結ぶ線分もまた、表紙高さ方向に対して略直交する。そして、薄肉部１４１の表紙高さ方向に沿った寸法は、貫通孔１５の表紙高さ方向に沿った寸法に略合致している。 In the present embodiment, the thin portion 141 is an intermediate portion in the cover height direction of the hinge 14 on the cover cover 11 side so as to be opposed to the through hole 15 described above. A line segment connecting one end (upper end along the cover height direction) of the through hole 15 and one end (upper end) of the thin portion 141 is substantially orthogonal to the cover height direction as the extending direction of the hinge 14. Similarly, the line segment connecting the other end (the lower end along the cover height direction) of the through hole 15 and the other end (the lower end) of the thin portion 141 is also substantially orthogonal to the cover height direction. The dimension along the cover height direction of the thin wall portion 141 substantially matches the dimension along the cover height direction of the through hole 15.

ポケット３は、例えば透明または透光性を有した薄い樹脂フィルムを袋状に成形した、いわゆるクリアポケットであり、その内に一枚または複数枚の紙葉類を挿入することができる。各ポケット３の内側端は、背表紙１２における表表紙１１寄りの領域に、溶着等により固着している。 The pocket 3 is a so-called clear pocket in which a thin resin film having transparency or translucency is formed into a bag shape, for example, and one or a plurality of paper sheets can be inserted therein. The inner end of each pocket 3 is fixed to a region near the front cover 11 of the spine cover 12 by welding or the like.

綴じ具２は、例えば樹脂製の一体成形品であり、ベース部２１と、ベース部２１に対向する押さえ部２３と、ベース部２１の内側端と押さえ部２３の内側端とを連結する背部２２と、ベース部２１と押さえ部２３との間で両者が対向する方向に伸長する綴じ桿２５とを備えている。 The binding tool 2 is, for example, an integrally molded product made of resin, and includes a base portion 21, a pressing portion 23 that faces the base portion 21, and a back portion 22 that connects the inner end of the base portion 21 and the inner end of the pressing portion 23. And a binding rod 25 extending between the base portion 21 and the pressing portion 23 in a direction in which both face each other.

ベース部２１は、表紙高さ方向に拡張し、かつ表紙幅方向即ち裏表紙１３の左右方向にも展伸した薄板状をなす。このベース部２１は、表紙体１の裏表紙１３の外表面（表表紙１１と向かい合う内向面とは反対側の面）に接合する部位である。つまり、図２、図６ないし図８に示しているように、本実施形態のファイルにあっては、綴じ具２のベース部２１が表紙体１の外側に表出する。ベース部２１は、裏表紙１３に対して、接着または溶着等により固着する。ベース部２１における、裏表紙１３に接合する側の面からは、綴じ桿２５の要素となる筒状部２５１が突出している。筒状部２５１は、ベース部２１が拡張する表紙高さ方向に沿った外側部（上端部及び下端部）に位置する。既に述べた通り、この筒状部２５１は、裏表紙１３に形成した挿通孔１６に挿通されて、表紙体１の内側に突き出す。 The base portion 21 has a thin plate shape that extends in the front cover height direction and extends in the front cover width direction, that is, in the left-right direction of the back cover 13. The base portion 21 is a portion that is joined to the outer surface of the back cover 13 of the cover body 1 (the surface opposite to the inward surface facing the cover 11). That is, as shown in FIGS. 2 and 6 to 8, in the file of the present embodiment, the base portion 21 of the binding tool 2 is exposed outside the cover body 1. The base portion 21 is fixed to the back cover 13 by adhesion or welding. A cylindrical portion 251 serving as an element of the binding rod 25 protrudes from the surface of the base portion 21 that is bonded to the back cover 13. The cylindrical part 251 is located in the outer part (upper end part and lower end part) along the cover height direction in which the base part 21 extends. As already described, the cylindrical portion 251 is inserted into the insertion hole 16 formed in the back cover 13 and protrudes to the inside of the cover body 1.

背部２２は、表紙高さ方向に拡張しており、その外寸がベース部２１及び押さえ部２３よりも拡大している。この背部２２とベース部２１との間には、ヒンジ２４を設けている。ヒンジ２４は、表紙高さ方向に沿って延伸する凹溝である。綴じ具２における、ヒンジ２４が存在する部分の厚みは、それ以外の部分（ベース部２１、背部２２及び押さえ部２３）の厚みよりも薄肉となる。このヒンジ２４により、背部２２及び押さえ部２３は、ベース部２１に対して、表紙高さ方向に沿って伸びる軸回りに回動することが可能となる。 The back portion 22 extends in the cover height direction, and its outer dimensions are larger than those of the base portion 21 and the holding portion 23. A hinge 24 is provided between the back portion 22 and the base portion 21. The hinge 24 is a concave groove extending along the cover height direction. In the binding tool 2, the thickness of the portion where the hinge 24 is present is thinner than the thickness of the other portions (the base portion 21, the back portion 22, and the pressing portion 23). With the hinge 24, the back portion 22 and the pressing portion 23 can be rotated around an axis extending along the cover sheet height direction with respect to the base portion 21.

押さえ部２３は、背部２２から一旦背幅方向即ちベース部２１及び裏表紙１３から離れてゆく方向に迫り上がり、その後湾曲してベース部２１及び裏表紙１３と略平行となるように延出している。押さえ部２３もまた、表紙高さ方向に拡張し、かつ表紙幅方向にも展伸した薄板状をなす。但し、ベース部２１と比較して、表紙幅方向に沿った外寸がより小さい。押さえ部２３における、ベース部２１及び裏表紙１３に対向する側の面からは、綴じ桿２５の要素となる軸部２５２が突出している。軸部２５２は、押さえ部２３が拡張する表紙高さ方向に沿った外側部（上端部及び下端部）に位置する。 The holding portion 23 temporarily rises from the back portion 22 in the width direction, that is, in a direction away from the base portion 21 and the back cover 13, and then bends and extends so as to be substantially parallel to the base portion 21 and the back cover 13. Yes. The holding portion 23 also has a thin plate shape that extends in the cover height direction and extends in the cover width direction. However, compared with the base part 21, the outer dimension along the cover width direction is smaller. A shaft portion 252 serving as an element of the binding rod 25 protrudes from the surface of the pressing portion 23 facing the base portion 21 and the back cover 13. The shaft portion 252 is located on the outer side (upper end and lower end) along the cover height direction in which the pressing portion 23 extends.

綴じ具２を使用して紙葉類を綴じる際には、まず、押さえ部２３及び背部２２を回動操作して、図８に示すように、押さえ部２３をベース部２１及び裏表紙１３から引き離す。このとき、押さえ部２３から突出している軸部２５２が、ベース部２１から突出している筒状部２５１から抜出される。その状態で、予め紙葉類に穿ってある綴じ孔に筒状部２５１を挿通するようにして、紙葉類の内側縁部をベース部２１の上に重ねて配置する。しかる後、押さえ部２３及び背部２２を回動操作して、図６または図７に示すように、押さえ部２３がベース部２１に対向する姿勢とし、かつ軸部２５２を筒状部２５１の内に挿入する。結果、筒状部２５１及び軸部２５２が綴じ桿２５となって、紙葉類がベース部２１と押さえ部２３との間に綴じ止められる。 When binding paper sheets using the binding tool 2, first, the pressing portion 23 and the back portion 22 are rotated to move the pressing portion 23 from the base portion 21 and the back cover 13 as shown in FIG. 8. Pull apart. At this time, the shaft portion 252 protruding from the pressing portion 23 is extracted from the cylindrical portion 251 protruding from the base portion 21. In this state, the inner edge of the paper sheet is placed on the base part 21 so that the tubular part 251 is inserted into a binding hole that has been previously formed in the paper sheet. Thereafter, the holding portion 23 and the back portion 22 are rotated to bring the holding portion 23 into a posture facing the base portion 21 as shown in FIG. 6 or FIG. Insert into. As a result, the cylindrical portion 251 and the shaft portion 252 become the binding rod 25, and the sheets are bound between the base portion 21 and the pressing portion 23.

表紙体１に取り付けた綴じ具２は、そのベース部２１が裏表紙１３の外表面に接合する一方で、その背部２２及び押さえ部２３が貫通孔１５を通過して裏表紙１３の内向面よりも内側に進入することとなる。貫通孔１５の内部には、綴じ具２におけるヒンジ１４及びその近傍の部位が入り込む。特に、図８に示すように表紙体１及び綴じ具２を開いている状態や、図６に示すように表紙体１及び綴じ具２を閉じている状態では、表紙体１の背表紙１２と綴じ具２の背部２２と略平行となるが、綴じ具２の背部２２が貫通孔１５に収容されることにより、表紙体１の背表紙１２と綴じ具２の背部２２とが干渉することが避けられる。 The binding tool 2 attached to the cover sheet 1 has its base portion 21 joined to the outer surface of the back cover 13, while its back portion 22 and pressing portion 23 pass through the through-hole 15 from the inward surface of the back cover 13. Will also enter the inside. Inside the through hole 15, the hinge 14 in the binding tool 2 and a portion in the vicinity thereof enter. In particular, when the cover body 1 and the binding tool 2 are opened as shown in FIG. 8 and when the cover body 1 and the binding tool 2 are closed as shown in FIG. Although it is substantially parallel to the back portion 22 of the binding tool 2, when the back portion 22 of the binding tool 2 is accommodated in the through hole 15, the back cover 12 of the cover body 1 and the back portion 22 of the binding tool 2 may interfere with each other. can avoid.

本実施形態では、表表紙１１、裏表紙１３並びにこれら表表紙１１及び裏表紙１３と接合する背表紙１２を有する表紙体１に、紙葉類を綴じ止めるための綴じ具２が取り付けられたファイルであって、前記背表紙１２と前記裏表紙１３との境界部位に、前記綴じ具２の所定部位（綴じ具２におけるヒンジ２４及び背部２２）を収容するための収容部（貫通孔１５）が形成されたファイルを構成した。 In the present embodiment, a file in which a binding tool 2 for binding paper sheets is attached to a cover body 1 having a front cover 11, a back cover 13, and a back cover 12 joined to the front cover 11 and the back cover 13. An accommodating portion (through hole 15) for accommodating a predetermined portion of the binding tool 2 (the hinge 24 and the back portion 22 of the binding tool 2) is provided at a boundary portion between the spine cover 12 and the back cover 13. Configured file formed.

本実施形態によれば、綴じ具２をできる限り表紙体１の背表紙１２側に寄せて配置することができる。従って、綴じ具２に綴じ止めた紙葉類もまた背表紙１２に近づくことになり、表表紙１１及び裏表紙１３の表紙幅を徒に大きくとらずとも、綴じ具２に綴じた紙葉類の外側縁部が表表紙１１または裏表紙１３からはみ出すことが回避される。つまり、表表紙１１及び裏表紙１３の表紙幅をより縮小してファイル全体の寸法をコンパクト化できる。 According to this embodiment, the binding tool 2 can be arranged as close to the spine cover 12 side of the cover body 1 as much as possible. Therefore, the paper sheets that are bound to the binding tool 2 also approach the spine cover 12, and the paper sheets that are bound to the binding tool 2 even if the cover widths of the front cover 11 and the back cover 13 are not made large. It is avoided that the outer edge portion of the outer surface of the front cover 11 protrudes from the front cover 11 or the back cover 13. That is, the size of the entire file can be reduced by further reducing the cover widths of the front cover 11 and the back cover 13.

また、綴じ具２のベース部２１を裏表紙１３の外表面側に露出させていることで、綴じ具２の押さえ部２３から裏表紙１３の内向面までの内寸をより大きく確保することができ、限られた背幅の内でより多くの枚数の紙葉類を綴じ具２に綴じることが可能となる。 Further, by exposing the base portion 21 of the binding tool 2 to the outer surface side of the back cover 13, it is possible to secure a larger inner dimension from the pressing portion 23 of the binding tool 2 to the inward surface of the back cover 13. It is possible to bind a larger number of paper sheets to the binding tool 2 within a limited back width.

並びに、本実施形態では、表紙体１における裏表紙１３側のヒンジ１４に跨って、またはこれに隣接して貫通する貫通孔１５が形成される一方、表表紙１１側のヒンジ１４の少なくとも一部に裏表紙１３側のヒンジ１４と比較して表紙体１の厚みをより薄くする薄肉部１４１が設けられている。これにより、裏表紙１３を背表紙１２に対して回動させる際の表紙体１の曲げこわさ（換言すれば、回動させるために必要な操作力）と、表表紙１１を背表紙１２に対して回動させる際の表紙体１の曲げこわさとが略均等となる。従って、裏表紙１３を開閉するときには柔らかいのに、表表紙１１を開閉するときには堅いというような違和感を使用者に与えることが回避される。 Moreover, in the present embodiment, a through-hole 15 is formed so as to pass through or adjacent to the hinge 14 on the back cover 13 side of the cover 1, while at least a part of the hinge 14 on the cover 11 side. Further, a thin portion 141 is provided to make the cover body 1 thinner than the hinge 14 on the back cover 13 side. As a result, the bending stiffness of the cover body 1 when the back cover 13 is rotated with respect to the spine 12 (in other words, the operating force necessary for the rotation), and the cover 11 with respect to the spine 12 The bending stiffness of the cover body 1 when being rotated is substantially equal. Therefore, it is possible to avoid giving the user an uncomfortable feeling that it is soft when the back cover 13 is opened and closed, but is hard when the cover 11 is opened and closed.

なお、本発明は以上に詳述した実施形態に限られるものではない。例えば、上記実施形態における、綴じ具２の所定部位２２、２４を収容するための収容部は、表紙体１を貫通する貫通孔１５であったが、図９に示すように、背表紙１２と前記裏表紙１３との境界部位に、表紙体１を貫通しない凹部１７を形成し、この凹部を綴じ具２の所定部位２２、２４を収容するための収容部とすることも可能である。図示例の凹部１７は、背表紙１２における裏表紙１３に隣接する部位に所在する。その上で、この凹部１７が存在する部分の厚みが、背表紙１２の他の部分の厚みよりも薄肉化する。 The present invention is not limited to the embodiment described in detail above. For example, in the above embodiment, the accommodating portion for accommodating the predetermined portions 22 and 24 of the binding tool 2 is the through hole 15 penetrating the cover body 1, but as shown in FIG. It is also possible to form a concave portion 17 that does not penetrate the cover body 1 at the boundary portion with the back cover 13 and use this concave portion as an accommodating portion for accommodating the predetermined portions 22 and 24 of the binding tool 2. The concave portion 17 in the illustrated example is located in a portion adjacent to the back cover 13 in the spine cover 12. In addition, the thickness of the portion where the concave portion 17 exists is thinner than the thickness of the other portion of the spine cover 12.

また、綴じ具２の所定部位２２、２４を収容するための収容部１５、１７を、背表紙１２と裏表紙１３との境界部位にではなく、背表紙１２と表表紙１１との境界部位に形成することも考えられる。この場合には、綴じ具２のベース部２１が、表表紙１１の外表面に接合することとなる。 In addition, the accommodating portions 15 and 17 for accommodating the predetermined portions 22 and 24 of the binding tool 2 are not located at the boundary portion between the spine cover 12 and the back cover 13 but at the boundary portion between the spine cover 12 and the front cover 11. Forming is also conceivable. In this case, the base portion 21 of the binding tool 2 is bonded to the outer surface of the front cover 11.

その他、各部の具体的な構成は、本発明の趣旨を逸脱しない範囲で種々変形が可能である。 In addition, the specific configuration of each part can be variously modified without departing from the spirit of the present invention.
