Description

【0001】
【発明の属する技術分野】
本発明は、構造簡素でありながら紙葉類を好適に綴じることができる綴じ足に関するものである。
【0002】
【従来の技術】
従来より、所定の間隔で紙葉類に設けられた2つの穴に挿し通すことにより紙葉類を束ねる綴じ足(ファスナー)が用いられている。綴じ足が使用される形態としては、表表紙や裏表紙に綴じ足を設けた、いわゆるファイル式のものや、表紙類を用いずに、綴じ足のみで紙葉類を綴じる形態のものがある。
【0003】
前記ファイル式のものには、保存目的で頻繁に閲覧する必要がない場合等は、より簡易な綴じ具が求められるため、特許文献1に記載のファイルに用いられているような樹脂製の綴じ足が多く開発されている。
【0004】
また、表紙類を用いず綴じ足のみで紙葉類を綴じる形態のものも存在する。このようなものは、上記同様保存目的の場合や、配布された書類を保存するまでの間、一時的に綴じておく目的などに使用され、安価な上、簡便に利用できるため一般に広く利用されている。これらのものは、綴じ足のみで紙葉類を綴じた形態を保持しなければならないため、その材質をスチールなどとしたものや、特許文献2のように、樹脂製の綴じ足に金属製の線材を長手方向に嵌合させ綴じ足のみで形態を保持することを可能にしたものなど、その全部または一部に金属を使用している。
【0005】

特許第3057558号公報
【特許文献2】
特開2002−316495号公報
【0006】
【発明が解決しようとする課題】
しかしながら、特許文献1に記載したような樹脂製の綴じ足では紙葉類を綴じるためには綴じ足のほかに、紙葉類に設けた穴から綴じ足の端部が抜けないよう固定するための別の部材が必須である。そのため、上記したような従来の樹脂製の綴じ足は、綴じ足のみで紙葉類を綴じる形態のものとすることはできない。また、綴じ足のみで紙葉類を綴じる形態のものはその全部または一部に金属を使用しているため、可燃ゴミである書類を廃棄する際には書類とは分別して廃棄しなければならない。
【0007】
本発明は、このような現状に鑑み、綴じ足のみで紙葉類を綴じる形態の綴じ足であって、構造簡素であっても少なくとも保存に必要な機能を備え、廃棄を好適に行うことができる綴じ足を提供しようとするものである。
【0008】
【課題を解決するための手段】
本発明は、かかる目的を達成するために、次のような構成を採用したものである。
【0009】
本発明にかかる綴じ足は、所定の間隔で紙に設けられた2つの穴に挿し通すことにより紙葉類を束ねる樹脂製の綴じ足であって、前記所定の間隔に略対応した長さの基部と、前記基部の長手方向に連続する位置に設けられた脚部とを備え、該脚部は少なくとも基部との隣接部分、及び当該脚部の一部の少なくとも2箇所に、互いに隣接し嵌合可能な凹部および凸部と、該凹部および凸部を屈曲可能に接続するヒンジ部を備え、前記ヒンジ部が直伸した状態において前記凹部および凸部は嵌合し、前記脚部が直伸状態に保持され、前記ヒンジ部が屈曲した状態において前記凹部および凸部の嵌合が解除され、前記脚部が屈曲状態に保持されることを特徴とする。
【0010】
このようなものであれば、紙葉類に設けられた穴に脚部を挿通しヒンジ部を屈曲させると、屈曲させた箇所では凹部および凸部の嵌合が解除され、前記脚部が直伸状態に戻ることなく屈曲状態に保持されるため、紙葉類に設けられた穴から前記脚部が抜け落ちることがない。したがって本発明に係る綴じ足は、素材として樹脂のみを用いても、紙を綴じるために綴じ足を固定する別の部材を用いることなく、綴じ足のみで紙葉類を綴じることを可能にする。
【0011】
また、上記凸部の突出部分は、該突出部分の端部の幅が該突出部分の基端部の幅よりも広い形状をしており、上記凹部のくぼみ部は前記凸部の突出部分と略同様の形状をしており、上記ヒンジ部が直伸した状態において前記凹部および凸部は嵌合することにより上記脚部が直伸状態に保持され、前記ヒンジ部が屈曲した状態において前記凸部の突出部分の側面であり前記突出部分の基端部の幅よりも広い部分と、前記凹部の先端部分が当接することにより前記脚部が屈曲状態に保持されるものである。
【0012】
上記凸部の突出部分から長手方向にスリットを設けることにより、上記脚部が直伸状態と屈曲状態との間を相互に移行する際に前記凸部の突出部分の幅が経過的に狭くなる構成や、上記凹部のくぼみ部にスリットを設けることにより、上記脚部が直伸状態と屈曲状態との間を相互に移行する際に前記凹部のくぼみ部の開口が経過的に広くなる構成とすることにより、上記脚部が直伸状態と屈曲状態とを、抵抗がかかることなく好適に相互の形態へ移行することができる。
【0013】
さらに、本発明にかかる綴じ足は、上記凹部、上記凸部及び前記ヒンジ部を長手方向に沿って所定ピッチで複数設けることにより、屈曲させる上記ヒンジ部を綴じようとする紙葉類の厚さに合わせて選択し、綴じることができる。
【0014】
本発明にかかる綴じ足は、1本の樹脂製の棒状体に複数の切り溝および切り込みを設けることのみにより作成できるため、組み立てにかかる労力、コストを削減することができ、安価での生産・販売が可能となる。
【0015】
そして、本発明にかかる綴じ足は、その材質をポリプロピレンまたはポリエチレンとすることにより、焼却処分の際にも有毒ガスが発生しにくく、可燃ゴミとして廃棄することや、綴じている紙葉類ごと廃棄することができる。
【0016】
【発明の実施の形態】
以下、本発明の一実施形態について、図面を参照して説明する。
【0017】
本実施形態に係る綴じ足1は、図1の平面図、図2(A)の拡大平面図および図2(B)の拡大側面図に示すように、所定の間隔で紙葉類に設けられた2つの穴に略対応した長さの基部2と、基部1の長手方向に連続する位置に設けられた脚部3とを備える。脚部3は、少なくとも基部2との隣接部分、及び当該脚部3の一部に、互いに隣接し嵌合可能に設けられた凹部31および凸部32と、凸部32の突出部分321に長手方向に設けたスリット322と、凹部31および凸部32を屈曲可能な厚さで接続するヒンジ部33と、紙葉類に設けられた2つの穴に挿通容易なように丸くすぼませた先端部34を具備するものである。ヒンジ部33が直伸した状態においては凹部31および凸部32は嵌合した状態となり脚部3が直伸状態に保持される。ヒンジ部33が屈曲した状態においては凹部31および凸部32の嵌合が解除され、脚部3が屈曲した状態に保持される構造を有する。
【0018】
ヒンジ部33を屈曲させるための構造及びその動作について図3を参照して説明する。
【0019】
凸部32の突出部分321は、その先端部の幅が基端部の幅よりも広くなっており、凹部31のくぼみ部311は凸部32の突出部分321と略同様の形状である。ヒンジ部33が直伸した状態においては凹部31および凸部32は嵌合することにより脚部3が直伸状態に保持される。ヒンジ部33が屈曲した状態においては凸部32の突出部分321のうち、当該突出部分321の基端部の幅よりも広い部分の前後面321bと、凹部31の先端部分の両側に位置する端面31aが当接することにより脚部3が屈曲状態に保持される。
【0020】
脚部3を直伸状態から屈曲状態へ移行させる際には、屈曲させる位置のヒンジ部33を手操作により一定以上の力で屈曲させることで屈曲状態とすることができるが、その際、凸部32の突出部分321の側面321aが凹部31のくぼみ部311の相対的に幅狭な内側にあたり、凸部32の突出部分321の幅は狭くなる方向に、凹部31のくぼみ部311は広くなる方向に力が加わることとなるが、長手方向に設けたスリット322により、凸部32の突出部分321の幅が経過的に狭くなるため、直伸状態から屈曲状態へと移行させる動作を、大きな操作力を加えることなく好適に行うことができる。一方、屈曲状態から直伸状態へと移行させる際には、屈曲した位置のヒンジ部33を手操作により一定以上の力で直伸させることで直伸状態とすることができるが、その際にもスリット322は上記と同様の働きをするため、好適に直伸状態とすることができる。これらの状態変移は、クリック感を伴って円滑になされる。
【0021】
なお、本実施形態に係る綴じ足1では、用いる樹脂の種類やヒンジ部33の厚み、綴じ足1そのものの厚みにより、屈曲・直伸させるために必要な力が種々変わり得るが、凸部32の突出部分321に設けるスリット322の幅を変えて凸部32の幅が狭くなる範囲や狭くするために必要な力の強さを調節することにより、綴じ足1を屈曲・直伸させるために必要な力の強さを適切なものとすることができる。
【0022】
本実施形態に係る綴じ足1は、凹部31および凸部32を一定間隔にそれぞれ複数設けているため、凹部31と凸部32の間に介在するするヒンジ部33も複数存在する。そうすることにより、屈曲させるヒンジ部33を綴じようとする紙葉類の厚さに応じて選択でき、選択したヒンジ部33に隣接する凹部31および凸部32を屈曲状態にすることができる。
【0023】
次に、本実施例に係る綴じ足1を用いて紙葉類を綴じる動作について説明する。図4は本実施例に係る綴じ足1を用いて紙葉類を綴じた状態を示した斜視図である。まず、基部2に最も近いヒンジ部33を屈曲させ、基部2の両端にある脚部3が基部2より略直角に起きあがるように配置し、綴じ足本体1の形状を略コの字状にする。このとき1対の脚部2間の距離は基部2の長さと略同じ、つまり紙葉類に設けられた2つの穴の間隔と略等しくなっている。次に、先端部34を紙葉類に設けられた穴に挿通し、紙葉類の厚みの下端が基部2に当たるまで挿通する。そして紙葉類の厚みの上端よりも高く且つ最も近い位置にあるヒンジ部33を屈曲させ紙葉類が先端部34から抜けないよう固定する。勿論、各脚部3ごとに紙葉類の穴に挿通して挿通端側を折り曲げる操作を順次行うようにしても構わない。
【0024】
なお、本発明は、以上に示した以外にも、種々変形が可能である。
【0025】
例えば、本実施形態を変形した例として、図5に示すように、スリットの位置を変えたものとして、凹部31のくぼみ部311にスリット312を設けることができる。この場合、直伸状態と屈曲状態との間を相互に移行させる際にはスリット312の働きにより凹部31のくぼみ部311の幅が広くなる。そうすることにより好適に直伸状態と屈曲状態との間を相互に移行させることができる。なお、凹部31のくぼみ部311に設けたスリット312の場合、凹部31の幅が広くなる範囲や広くするために必要な力の強さは、スリット312の長さを変えることにより調節することができる。
【0026】
以上のように、本実施形態は、所定の間隔で紙に設けられた2つの穴に挿し通すことにより紙葉類を束ねる樹脂製の綴じ足1であって、所定の間隔に略対応した長さの基部2と、基部2の長手方向に連続する位置に設けられた脚部3とを備え、脚部3は少なくとも基部2との隣接部分、及び当該脚部3の一部の少なくとも2箇所に、互いに隣接し嵌合可能な凹部31および凸部32と、凹部31および凸部32を屈曲可能に接続するヒンジ部33を備え、ヒンジ部33が直伸した状態において凹部31および凸部32は嵌合し、脚部3が直伸状態に保持され、ヒンジ部33が屈曲した状態において凹部31および凸部32の嵌合が解除され、脚部3が屈曲状態に保持されるようにしたものである。
【0027】
このようなものであれば、紙葉類に設けられた穴に脚部3を挿通しヒンジ部33を屈曲させると、屈曲させた箇所では凹部31および凸部32の嵌合が解除され、脚部3が直伸状態に戻ることなく屈曲状態に保持されるため、紙葉類に設けられた穴から脚部3が抜け落ちることがない。したがって本実施形態に係る綴じ足1は、素材として樹脂のみを用いても、紙を綴じるために綴じ足を固定する別の部材を用いることなく、綴じ足のみで紙葉類を綴じることを可能にする。
【0028】
特に、この実施形態において、凸部32の突出部分321は、該突出部分321の端部の幅が突出部分321の基端部の幅よりも広い形状をしており、凹部31のくぼみ部311は凸部32の突出部分321と略同様の形状をしており、ヒンジ部33が直伸した状態において凹部31および凸部32は嵌合することにより脚部3が直伸状態に保持され、ヒンジ部33が屈曲した状態において凸部32の突出部分の321のうち、当該突出部分321の基端部の幅よりも広い部分の前後面321bと、凹部31の先端部分の両側に位置する端面31aが当接することにより脚部3が屈曲状態に保持されるように構成している。このため、屈曲状態において、凹部31および凸部32が一定の広がりをもって当接した、安定した状態が保たれるため、紙葉類を安定して綴じることができる。
【0029】
また、この実施形態において凸部32の突出部分321から長手方向にスリット322を設けることにより、脚部3が直伸状態と屈曲状態との間を相互に移行する際に凸部32の突出部分321の幅が経過的に狭くなるように構成している。このため、脚部3が直伸状態と屈曲状態との間で、大きな抵抗がかかることなくかつ樹脂の弾性を利用して好適に相互の形態へ移行することができる。
【0030】
この実施形態を変形した例において、凹部31のくぼみ部311にスリット312を設けることにより、脚部3が直伸状態と屈曲状態との間を相互に移行する際に凹部31のくぼみ部311の開口幅が経過的に広くなるように構成している。このようにしても、上記と同様に、脚部3が直伸状態と屈曲状態とを、大きな抵抗がかかることなくかつ樹脂の弾性を利用して好適に相互の形態へ移行することができる。
【0031】
加えて、この実施形態において、凹部31、凸部32及びヒンジ部33を長手方向に沿って所定ピッチで複数設け、屈曲させるヒンジ部33を必要に応じて選択し、選択した該ヒンジ部33に隣接する凹部31および凸部33を屈曲状態にするように構成している。このため、屈曲させる上記ヒンジ部33を、綴じようとする紙葉類の厚さに合わせて選択し、綴じることができる。
【0032】
本実施形態に係る綴じ足1は、1本の樹脂製の棒状体に切り溝および切り込みを設けることで凹部31、凸部32、ヒンジ部33およびスリット322を作成することができる。すなわち、本実施形態に係る綴じ足1は、1つの樹脂成形体からの作成が可能であるため、生産にかかる労力、コストを削減することができ、安価での生産・販売が可能である。
【0033】
そして、本実施形態にかかる綴じ足1は、その材質をポリプロピレンまたはポリエチレンとすることにより、焼却処分の際にも有毒ガスが発生しにくく、綴じている紙葉類と分別することなく可燃ゴミとして廃棄することができる。
【0034】
以上、本発明の実施形態について説明したが、各部の具体的な構成は、上述した実施形態のみに限定されるものではなく、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。
【0035】
たとえば、上記実施形態では綴じ足のみで紙葉類を綴じる綴じ足について説明したが、本発明に係る他の実施形態として、綴じ足を表表紙または裏表紙に取り付けた、いわゆるファイル式の綴じ具にも用いることができる。この場合には、基部の端部と脚部の角度を直角とすることにより、脚部の直立ち上がりを綴じようとする紙葉類に対し垂直方向とし、紙を綴じる箇所にのみ屈曲可能な構造とすることも可能である。このように、いわゆるファイル式の綴じ具に本発明に係る綴じ足を用いた場合においても、紙を綴じるために綴じ足を固定する別の部材が不要であること、可燃ゴミとして紙葉類ごと廃棄できることといった上記実施形態と同様の効果を奏することができる。
【0036】
【発明の効果】
本発明は、以上説明した構成により、素材として樹脂のみを用いても、綴じ足のみで紙葉類を綴じることを可能にした。また、本発明にかかる綴じ足は、1本の樹脂製の棒状体に複数の切り溝および切り込みを設けることのみにより作成できるため、生産にかかる労力、コストを削減することができ、安価での販売が可能となる。さらに、その樹脂の材質をポリプロピレンまたはポリエチレンとすることにより、焼却処分の際にも有毒ガスが発生しにくく、可燃ゴミとして廃棄することができや、紙用類ごと廃棄することができる。

TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binding foot capable of suitably binding paper sheets while having a simple structure.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, binding feet (fasteners) that bundle paper sheets by inserting them into two holes provided in the paper sheets at predetermined intervals have been used. As a form in which the binding feet are used, there are a so-called file type in which binding feet are provided on the front cover and the back cover, and a form in which sheets are bound only with the binding feet without using the front cover. .
[0003]
In the case of the file type, when it is not necessary to frequently browse for the purpose of storage, etc., a simpler binding tool is required. Therefore, a resin binding as used in the file described in Patent Document 1 is required. Many feet are being developed.
[0004]
There is also a form in which sheets are bound only with binding feet without using covers. These are used for the purpose of preservation as described above, or for the purpose of temporarily binding until the distributed documents are preserved, and are widely used in general because they are inexpensive and easy to use. ing. Since these materials must maintain the form in which paper sheets are bound only with the binding feet, the material is made of steel or the like, or a metal binding is made of a resin binding foot as in Patent Document 2. Metal is used for all or part of the wire, such as a wire that can be fitted in the longitudinal direction to maintain its shape only with the binding feet.
[0005]
[Patent Document 1]
Japanese Patent No. 3057558 [Patent Document 2]
Japanese Patent Application Laid-Open No. 2002-316495
[Problems to be solved by the invention]
However, in the case of a resin binding foot as described in Patent Literature 1, in order to bind sheets, in addition to the binding feet, the binding feet are fixed so that the ends of the binding feet do not fall out of holes provided in the sheets. Another member is essential. For this reason, the conventional resin binding feet as described above cannot be configured to bind sheets only with the binding feet. In addition, paper sheets that are bound only with the binding feet use metal for all or part of the paper sheets. Therefore, when discarding combustible waste documents, they must be separated from the documents and discarded. .
[0007]
In view of the above situation, the present invention is a binding foot configured to bind sheets only with the binding feet, and has at least a function necessary for storage even with a simple structure, and can be disposed of properly. The goal is to provide a binding foot that can be used.
[0008]
[Means for Solving the Problems]
The present invention employs the following configuration in order to achieve the above object.
[0009]
The binding foot according to the present invention is a resin binding foot that bundles paper sheets by being inserted through two holes provided in the paper at a predetermined interval, and has a length substantially corresponding to the predetermined interval. A base provided with a leg provided at a position continuous with the base in a longitudinal direction, wherein the leg is adjacently fitted to at least a portion adjacent to the base and at least two places of a part of the leg. A concave portion and a convex portion that can be combined with each other, and a hinge portion that connects the concave portion and the convex portion so that the concave portion and the convex portion can be bent. The fitting of the concave portion and the convex portion is released when the hinge portion is held and the hinge portion is bent, and the leg portion is held in a bent state.
[0010]
In such a case, when the leg portion is inserted into the hole provided in the paper sheet and the hinge portion is bent, the fitting of the concave portion and the convex portion is released at the bent portion, and the leg portion is straightened. Since the legs are kept in the bent state without returning to the state, the legs do not fall out from the holes provided in the paper sheets. Therefore, the binding foot according to the present invention enables paper sheets to be bound only with the binding feet without using another member for fixing the binding feet in order to bind paper, even if only the resin is used as the material. .
[0011]
Further, the projecting portion of the convex portion has a shape in which the width of the end portion of the projecting portion is wider than the width of the base end portion of the projecting portion. In the state where the hinge portion is straightened, the leg portion is held in a straightened state by fitting the concave portion and the convex portion in a state where the hinge portion is straightened, and the convex portion is held in a state where the hinge portion is bent. The leg portion is held in a bent state by abutting a side surface of the protruding portion, which is wider than a width of a base end portion of the protruding portion, and a distal end portion of the concave portion.
[0012]
By providing a slit in the longitudinal direction from the projecting portion of the projection, the width of the projecting portion of the projection gradually narrows when the leg transitions between the straight extension state and the bent state. Alternatively, by providing a slit in the concave portion of the concave portion, the opening of the concave portion of the concave portion may be gradually widened when the leg portion transitions between the straight extension state and the bent state. Thereby, the leg portion can be suitably shifted from the straight extension state and the bent state to the mutual form without applying resistance.
[0013]
Further, the binding foot according to the present invention, by providing a plurality of the concave portion, the convex portion and the hinge portion at a predetermined pitch along the longitudinal direction, the thickness of the paper sheet to bind the hinge portion to be bent Can be selected and bound.
[0014]
Since the binding foot according to the present invention can be created only by providing a plurality of cut grooves and cuts in a single resin bar, labor and cost required for assembly can be reduced, and production and production at low cost can be achieved. Sales become possible.
[0015]
The binding foot according to the present invention, by using polypropylene or polyethylene as its material, hardly generates toxic gas even during incineration disposal, and can be discarded as combustible waste or discarded together with bound sheets. can do.
[0016]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0017]
As shown in the plan view of FIG. 1, the enlarged plan view of FIG. 2A, and the enlarged side view of FIG. 2B, the binding feet 1 according to the present embodiment are provided on paper sheets at predetermined intervals. A base 2 having a length substantially corresponding to the two holes, and a leg 3 provided at a position continuous in the longitudinal direction of the base 1. The leg 3 has a concave portion 31 and a convex portion 32 which are provided at least in a portion adjacent to the base portion 2 and a part of the leg portion 3 so as to be adjacent to each other so as to be fitted to each other. The slit 322 provided in the direction, the hinge portion 33 connecting the concave portion 31 and the convex portion 32 with a bendable thickness, and the tip which is rounded so as to be easily inserted into two holes provided in the paper sheet. A part 34 is provided. When the hinge portion 33 is straightened, the concave portion 31 and the convex portion 32 are in the fitted state, and the leg 3 is held in the straightened state. When the hinge portion 33 is bent, the fitting between the concave portion 31 and the convex portion 32 is released, and the leg 3 is held in a bent state.
[0018]
The structure for bending the hinge portion 33 and its operation will be described with reference to FIG.
[0019]
The protruding portion 321 of the protruding portion 32 has a width at the tip end portion larger than the width at the base end portion, and the recessed portion 311 of the recessed portion 31 has substantially the same shape as the protruding portion 321 of the protruding portion 32. When the hinge part 33 is straightened, the leg 31 is held in the straightened state by fitting the concave part 31 and the convex part 32. When the hinge portion 33 is bent, the front and rear surfaces 321 b of the protruding portion 321 of the protruding portion 32 that is wider than the width of the base end of the protruding portion 321, and the end surfaces located on both sides of the distal end portion of the recess 31. The leg 3 is held in a bent state by the contact of the leg 31a.
[0020]
When the leg 3 is shifted from the straight extension state to the bent state, the hinge section 33 at the position to be bent can be bent by manually operating the hinge section 33 with a certain force or more. 32, the side surface 321a of the protruding portion 321 corresponds to the relatively narrow inner side of the concave portion 311 of the concave portion 31, the width of the protruding portion 321 of the convex portion 32 decreases, and the concave portion 311 of the concave portion 31 increases. However, since the width of the protruding portion 321 of the convex portion 32 gradually decreases due to the slit 322 provided in the longitudinal direction, the operation of shifting from the straight extension state to the bending state requires a large operation force. Can be suitably carried out without adding any of them. On the other hand, when shifting from the bent state to the straight stretched state, the hinge part 33 at the bent position can be straightened by a manual operation with a certain force or more, and the straight stretch state can be obtained. Has the same function as described above, so that it can be preferably in a straightly stretched state. These state transitions are smoothly performed with a click feeling.
[0021]
In the binding foot 1 according to the present embodiment, the force required for bending and straightening can be variously changed depending on the type of resin used, the thickness of the hinge part 33, and the thickness of the binding foot 1 itself. By changing the width of the slit 322 provided in the protruding portion 321 to adjust the range in which the width of the convex portion 32 becomes narrow or the strength of the force required to make the width narrow, it is necessary to bend and straighten the binding foot 1. The strength of power can be made appropriate.

Since the binding leg 1 according to the present embodiment is provided with a plurality of concave portions 31 and a plurality of convex portions 32 at regular intervals, there are also a plurality of hinge portions 33 interposed between the concave portions 31 and the convex portions 32. By doing so, the hinge portion 33 to be bent can be selected according to the thickness of the sheet to be bound, and the concave portion 31 and the convex portion 32 adjacent to the selected hinge portion 33 can be bent.
[0023]
Next, an operation of binding sheets using the binding feet 1 according to the present embodiment will be described. FIG. 4 is a perspective view illustrating a state in which sheets are bound using the binding feet 1 according to the present embodiment. First, the hinge portion 33 closest to the base 2 is bent, and the legs 3 at both ends of the base 2 are arranged so as to rise substantially at right angles to the base 2 so that the shape of the binding foot main body 1 is substantially U-shaped. . At this time, the distance between the pair of leg portions 2 is substantially equal to the length of the base portion 2, that is, substantially equal to the interval between two holes provided in the paper sheet. Next, the leading end portion 34 is inserted into a hole provided in the paper sheet, and is inserted until the lower end of the thickness of the paper sheet hits the base 2. Then, the hinge portion 33 located at a position higher and closest to the upper end of the thickness of the paper sheet is bent so that the paper sheet is fixed so as not to come off from the front end portion. Needless to say, the operation of inserting the leg portion 3 into the hole of the paper sheet and bending the insertion end side may be sequentially performed.
