It relates to a binding tool that opens and closes the ring portion by being rotationally displaced.

この種の綴じ具として従来は、たとえば特許文献1に記載されたものがある。 Conventionally, as a binding tool of this kind, there is one described in Patent Document 1, for example.

特許文献1には、「相互に衝合し得る複数の半環状の綴環をそれぞれ有し且つ内辺で互いに衝合した第1及び第2基板と、前記両基板の両外辺を拘束して前記基板の弾発的な上下運動による前記綴環の開閉を許容する弾性さやと、前記両基板の長手方向の少なくとも一端部において前記第1及び第2基板にそれぞれ一体に形成され且つ前記長手方向に隣接して互いに交差して形成されている第1及び第2操作つまみと、を有するルースリーフ綴具において、前記第1及び第2操作つまみの少なくとも一方の操作つまみは相手側の操作つまみの方へ突出する係止突起を有し、他方の操作つまみは前記綴環が閉鎖する位置で前記係止突起と係止する係止部を有し、前記両操作つまみを綴環の開放方向に押したときに前記第1及び第2操作つまみが前記長手方向に互いに離れる力成分を生じるように前記両操作つまみを構成したことを特徴とするルースリーフ綴具」が開示されている。 Patent Document 1 states that "the first and second substrates having a plurality of semi-annular bound rings that can be mutually abutted and abutting each other on the inner side, and both outer sides of the two substrates are constrained. The elastic sheath that allows the opening and closing of the binding ring due to the elastic vertical movement of the substrate, and the longitudinal length that is integrally formed with the first and second substrates at at least one end in the longitudinal direction of both the substrates.

上述したような綴じ具では、綴じ具の構成部品である弾性保持部材や基板の材質、寸法ないし形状その他の条件によっては、弾性保持部材による基板の押付け力が十分に得られないことがある。 With the binding tool as described above, the pressing force of the substrate by the elastic holding member may not be sufficiently obtained depending on the material, dimensions, shape and other conditions of the elastic holding member which is a component of the binding tool and the substrate.

この場合、綴じリングに綴じるルーズリーフ用紙等の紙葉の枚数が多いと、綴じリングを構成する対をなすリング部を閉じた状態に維持することが困難になり、紙葉を綴じ込む枚数に制約が生じる。 In this case, if the number of sheets of loose-leaf paper or the like to be bound to the binding ring is large, it becomes difficult to keep the paired ring portions constituting the binding ring in a closed state, and the number of sheets to be bound is limited. Occurs.

このことは特に、弾性保持部材の材質を金属材料から樹脂含有材料に変更し、それによって弾性保持部材による基板の押付け力が低下したときに顕在化し得る。 This can be manifested especially when the material of the elastic holding member is changed from the metal material to the resin-containing material, whereby the pressing force of the substrate by the elastic holding member is reduced.

この発明は、上記のような問題に対処するべくなされたものであり、その目的は、紙葉を有効に綴じ込むことができる綴じ具を提供することにある。 The present invention has been made to address the above problems, and an object of the present invention is to provide a binding tool capable of effectively binding paper sheets.

この発明の綴じ具は、綴じリングを構成する対をなすリング部のそれぞれが設けられた二枚の基板と、二枚の前記基板を幅方向の外側から挟み込み、それらの基板を互いに押し付けて保持する弾性保持部材とを有し、弾性保持部材による押付け力の作用下での前記基板の回転支点周りの回転変位に伴い、前記リング部が開閉するものであって、二枚の前記基板のそれぞれの内側面に、前記回転変位の途中で互いに衝突し、前記押付け力に抗して乗り越えて当該回転変位に抵抗する対向突起部が設けられており、二枚の前記基板のそれぞれの内側面が、前記対向突起部のそれぞれが形成されて互いに嵌り合う突起付き凸面及び突起付き凹面を有するものである。 The binding tool of the present invention sandwiches two substrates provided with each of the paired ring portions constituting the binding ring and the two substrates from the outside in the width direction, and presses the substrates against each other to hold them. The ring portion opens and closes with the rotational displacement around the rotation fulcrum of the substrate under the action of the pressing force of the elastic holding member. On the inner surface of the substrate, opposed protrusions that collide with each other in the middle of the rotational displacement, overcome the pressing force, and resist the rotational displacement are provided, and the inner surfaces of the two substrates are respectively provided. , Each of the facing protrusions is formed and has a convex surface with protrusions and a concave surface with protrusions that fit each other .

また、前記対向突起部は、前記基板の長手方向で複数対設けられていることが好ましい。 Further, it is preferable that a plurality of pairs of the facing protrusions are provided in the longitudinal direction of the substrate.

二枚の前記基板のそれぞれの内側面は、前記回転変位の回転支点となる支点凸部及び支点凹部を有することができる。 The inner surface of each of the two substrates may have a fulcrum convex portion and a fulcrum concave portion that serve as a rotational fulcrum of the rotational displacement.

この場合、前記対向突起部は、前記基板の長手方向で、前記支点凸部及び支点凹部に隣接する位置に設けられていることが好適である。 In this case, it is preferable that the facing protrusion is provided at a position adjacent to the fulcrum convex portion and the fulcrum concave portion in the longitudinal direction of the substrate.

またここでは、前記支点凸部がシャフト状であり、前記支点凹部がブッシュ状であり、前記支点凸部が前記支点凹部に、前記回転変位を可能に嵌め込まれていることが好ましい。 Further, here, it is preferable that the fulcrum convex portion has a shaft shape, the fulcrum concave portion has a bush shape, and the fulcrum convex portion is fitted into the fulcrum concave portion so as to be able to perform the rotational displacement.

なお、前記基板のそれぞれの長手方向の両端部には、互いに交差して延びて先端部分の離隔・接近変位により前記リング部の開閉操作が可能な開閉操作部を設けることができる。 It should be noted that, at both ends of each of the substrates in the longitudinal direction, an opening / closing operation portion that extends so as to intersect each other and can open / close the ring portion by separating / approaching the tip portion can be provided.

上記の綴じ具は、前記弾性保持部材が、樹脂材料を含む材質からなることが好ましい。 In the above binding tool, it is preferable that the elastic holding member is made of a material including a resin material.

より好ましくは、前記材質が紙材料を含む。 More preferably, the material includes a paper material.

この発明の綴じ具によれば、二枚の前記基板のそれぞれの内側面に、前記回転変位の途中で互いに衝突し、前記押付け力に抗して乗り越えて当該回転変位に抵抗する対向突起部を設けたことにより、紙葉を有効に綴じ込むことができる。 According to the binding tool of the present invention, on the inner surface of each of the two substrates, opposed protrusions that collide with each other in the middle of the rotational displacement, overcome the pressing force, and resist the rotational displacement are provided.

以下に図面を参照しながら、この発明の実施の形態について詳細に説明する。
図1に例示する綴じ具1は、互いに隣接して平行に延びる二枚の基板2、3と、二枚の基板2、3を幅方向の外側から挟み込み、それらの基板2、3を互いに押し付けて保持する弾性保持部材4とを有するものである。
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
In the binding tool 1 illustrated in FIG. 1, two substrates 2 and 3 extending in parallel adjacent to each other and two substrates 2 and 3 are sandwiched from the outside in the width direction, and the substrates 2 and 3 are pressed against each other. It has an elastic holding member 4 for holding.

ここで、基板2、3のそれぞれには、表面Sf側に、たとえば半円の円弧状等の所定の形状で延びる対をなすリング部Rbのそれぞれが設けられている。各基板2、3に設けたリング部Rbの先端部分が相互に接触した状態で、リング部Rbが閉じて、ルーズリーフ用紙その他の紙葉が綴じ込まれる綴じリングが構成される。リング部Rbは、図示の例では五対設けているが、一対~四対または六対以上設けることもできる。また、リング部Rbの形状は、対をなすものどうしで綴じリングを構成できるものであれば、円弧状のものに限らない。なお、対をなすリング部Rbのそれぞれの先端面には、必要に応じて、接触時に嵌り合う突出部2a又は孔部2bを形成してもよい。 Here, each of the substrates 2 and 3 is provided with a pair of ring portions Rb extending in a predetermined shape such as a semicircular arc on the surface Sf side. In a state where the tip portions of the ring portions Rb provided on the substrates 2 and 3 are in contact with each other, the ring portions Rb are closed to form a binding ring into which loose-leaf paper or other paper leaves are bound. Although five pairs of ring portions Rb are provided in the illustrated example, one to four pairs or six or more pairs may be provided. Further, the shape of the ring portion Rb is not limited to the arc shape as long as the binding ring can be formed by paired ones. If necessary, a protruding portion 2a or a hole portion 2b that fits at the time of contact may be formed on the respective tip surfaces of the paired ring portions Rb.

またここで、図示の例では、弾性保持部材4は、たとえば、基板2、3の長手方向で基板2、3とほぼ同等又は、基板2、3よりも若干短い長さを有する板状のものであって、本体部4aと、本体部4aの両側縁のそれぞれから立ち上がる側部4bとを有するものとしている。そしてここでは、側部4bの外端4cを基板2、3側に内向きに形成し、基板2、3の外側面Seに設けた窪み部分2cに係合させている(図5(a)参照)。基板2、3の幅と弾性保持部材4の幅等の寸法を調整することにより、弾性保持部材4で基板2、3に所要の押付け力を作用させることができる。 Here, in the illustrated example, the elastic holding member 4 is, for example, a plate-shaped member having a length substantially equal to or slightly shorter than the substrates 2 and 3 in the longitudinal direction of the substrates 2 and 3. It is assumed that the main body portion 4a has a main body portion 4a and side portions 4b rising from each of both side edges of the main body portion 4a. Here, the outer end 4c of the side portion 4b is formed inward on the substrates 2 and 3 sides, and is engaged with the recessed portion 2c provided on the outer surface Se of the substrates 2 and 3 (FIG. 5A). reference). By adjusting the dimensions such as the width of the substrates 2 and 3 and the width of the elastic holding member 4, the elastic holding member 4 can exert a required pressing force on the substrates 2 and 3.

綴じ具1をユーザが操作するに当り、弾性保持部材4による押付け力の作用下で基板2、3をその内側面Si側の後述の回転支点の周りで回転変位させると、基板2、3とともにリング部Rbが変位して、リング部Rbが開閉する。ユーザは、リング部Rbの先端部分が離隔してリング部Rbが開いた状態で、紙葉に設けられる穴部にリング部Rbを通し、その後にリング部Rbの先端部分を接触させてリング部Rbを閉じた状態とすることで、紙葉が綴じ具1に綴じ込まれる。 When the user operates the binding tool 1, the substrates 2 and 3 are rotationally displaced around the rotation fulcrum described later on the inner side surface Si side under the action of the pressing force of the elastic holding member 4, and the substrates 2 and 3 are together. The ring portion Rb is displaced, and the ring portion Rb opens and closes. The user passes the ring portion Rb through the hole provided in the paper leaf in a state where the tip portion of the ring portion Rb is separated and the ring portion Rb is opened, and then the tip portion of the ring portion Rb is brought into contact with the ring portion. By keeping Rb closed, the paper sheet is bound to the binding tool 1.

このような綴じ具1では、弾性保持部材4や基板2、3の材質、寸法ないし形状その他の条件によっては、弾性保持部材4による基板2、3の押付け力が十分に得られず、多数枚の紙葉を確実に綴じ込むことができなくなる場合がある。それにより、綴じ具1に綴じ込むことが可能な紙葉の枚数が制限される。 With such a binding tool 1, depending on the material, size, shape and other conditions of the elastic holding member 4 and the substrates 2 and 3, the pressing force of the substrates 2 and 3 by the elastic holding member 4 cannot be sufficiently obtained, and a large number of sheets are obtained. It may not be possible to reliably bind the paper leaves. As a result, the number of sheets of paper that can be bound to the binding tool 1 is limited.

これに対処するため、この実施形態では、二枚の基板2、3のそれぞれの内側面Siに、図2、4に示すように、基板2、3の回転変位の途中で互いに衝突するとともに、弾性保持部材4による押付け力に抗して乗り越えて回転変位に抵抗する対向突起部5を設ける。図3に示すところでは必ずしも明確ではないが、他方の基板3にも、長手方向で一方の基板2に設けた対向突起部5と対応する位置に対向突起部5が設けられる。 In order to deal with this, in this embodiment, the inner side surfaces Si of the two substrates 2 and 3 collide with each other in the middle of the rotational displacement of the substrates 2 and 3 as shown in FIGS. The facing protrusion 5 is provided to resist the pressing force of the elastic holding member 4 and to resist the rotational displacement. Although it is not always clear as shown in FIG. 3, the other substrate 3 is also provided with the facing protrusion 5 at a position corresponding to the facing protrusion 5 provided on the one substrate 2 in the longitudinal direction.

このことによれば、基板2、3の回転変位に際し、二枚の基板2、3のそれぞれに設けた対向突起部5が、互いに衝突して乗り越えるときに回転変位に抵抗するので、相互に接触して閉じたリング部Rbが容易に開かなくなる。その結果として、比較的多い枚数の紙葉であっても有効に綴じ込むことができる。 According to this, when the substrates 2 and 3 are rotationally displaced, the facing protrusions 5 provided on each of the two substrates 2 and 3 resist the rotational displacement when they collide with each other and get over, so that they come into contact with each other. Then, the closed ring portion Rb cannot be easily opened. As a result, even a relatively large number of paper sheets can be effectively bound.

より詳細には、リング部Rbが閉じた状態では、図5(a)に示すように、各基板2、3の対向突起部5は、基板2、3の厚み方向(同図の上下方向)に互いにずれて位置する。 More specifically, when the ring portion Rb is closed, as shown in FIG. 5A, the facing protrusions 5 of the substrates 2 and 3 are in the thickness direction of the substrates 2 and 3 (vertical direction in the figure). It is located offset from each other.

この状態から基板2、3が回転変位すると、図5(b)に示すように、各基板2、3の対向突起部5が互いに衝突して乗り上がる。これにより、二枚の基板が相互に引き離される向きに僅かに変位し、弾性保持部材4が押し広げられるので、その弾性変形量の増大に伴って基板2、3に大きな押付け力が作用する。その際に、回転変位に対する抵抗が生じる。これがリング部Rbの意図しない開きを抑制する。 When the substrates 2 and 3 are rotationally displaced from this state, the facing protrusions 5 of the substrates 2 and 3 collide with each other and ride on each other as shown in FIG. 5 (b). As a result, the two substrates are slightly displaced in the direction in which they are separated from each other, and the elastic holding member 4 is expanded, so that a large pressing force acts on the substrates 2 and 3 as the amount of elastic deformation increases. At that time, resistance to rotational displacement occurs. This suppresses the unintended opening of the ring portion Rb.

ユーザがリング部Rbを開くため、基板2、3をさらに回転変位させた場合、各基板2、3の対向突起部5は互いの上を乗り越えて通過し、図5(c)に示すように、厚み方向にずれた位置に移動する。それとともにリング部Rbが開き、ユーザは、綴じ具1に対する紙葉の着脱を行うことができる。リング部Rbが開いた状態から閉じた状態にする際にも、そのときの回転変位に対して、対向突起部5の乗り上げによる抵抗が生じる。 When the board 2 and 3 are further rotationally displaced in order to open the ring portion Rb, the facing protrusions 5 of the boards 2 and 3 pass over each other and pass over each other, as shown in FIG. 5 (c). , Move to a position displaced in the thickness direction. At the same time, the ring portion Rb opens, and the user can attach / detach the paper leaf to / from the binding tool 1. Even when the ring portion Rb is changed from the open state to the closed state, resistance is generated due to the riding of the facing protrusion portion 5 against the rotational displacement at that time.

二枚の基板2、3の各内側面Siは、図2~5に示すように、上記の対向突起部5が設けられて互いに嵌り合う突起付き凸面6及び突起付き凹面7のそれぞれを有することが好ましい。これにより、基板2、3の回転変位に伴い、突起付き凹面7内で突起付き凸面6が摺動する途中で、それらの突起付き凸面6及び突起付き凹面7に設けた対向突起部5が衝突して乗り越えるので、回転変位を円滑に安定して行わせつつ、回転変位に対する抵抗を付与することができる。 As shown in FIGS. 2 to 5, each of the inner side surface Sis of the two substrates 2 and 3 has a convex surface 6 with protrusions and a concave surface 7 with protrusions, each of which is provided with the above-mentioned facing protrusions 5 and fits with each other. Is preferable. As a result, the convex surface 6 with protrusions collides with the convex surface 6 with protrusions 6 and the facing protrusions 5 provided on the concave surface 7 with protrusions while the convex surface 6 with protrusions slides in the concave surface 7 with protrusions due to the rotational displacement of the substrates 2 and 3. Therefore, it is possible to impart resistance to the rotational displacement while smoothly and stably performing the rotational displacement.

この場合、対向突起部5は、突起付き凸面6や突起付き凹面7上で基板2、3の厚み方向の一部の領域に、当該表面から突出させて設けることができる。基板2、3の厚み方向にて突起付き凸面6や突起付き凹面7上での対向突起部5を設ける位置は、対向突起部5で抵抗力を付与するリング部Rbの開閉位置等を考慮して決定することが望ましい。 In this case, the facing protrusions 5 can be provided on the convex surface 6 with protrusions or the concave surface 7 with protrusions in a part of the regions of the substrates 2 and 3 in the thickness direction so as to project from the surface. The position where the convex surface 6 with protrusions 6 and the facing protrusion 5 on the concave surface 7 with protrusions are provided in the thickness direction of the substrates 2 and 3 takes into consideration the opening / closing position of the ring portion Rb to which the resistance force is applied by the facing protrusions 5. It is desirable to decide.

突起付き凸面6及び突起付き凹面7は対向突起部5を含め、図示の例のように、曲面で構成することが好適である。また、基板2、3の厚み方向にて、突起付き凸面6上及び突起付き凹面7上のそれぞれで対向突起部5を隔てた両側の表面は、図5に示すように、対向突起部5がそれと向き合う対向突起部5を乗り越えた後に入り込むように凹状に若干窪ませて形成することが好ましい。 It is preferable that the convex surface 6 with protrusions 6 and the concave surface 7 with protrusions include a facing protrusion 5 and are formed of a curved surface as shown in the illustrated example. Further, as shown in FIG. 5, the facing protrusions 5 are formed on the surfaces on both sides of the convex surface 6 with protrusions and the concave surface 7 with protrusions on both sides of the substrate 2 and 3 with the facing protrusions 5 separated from each other. It is preferable to form it by slightly denting it in a concave shape so as to enter after getting over the facing protrusion 5 facing it.

各基板2、3に設けられて対をなす対向突起部5は、基板2、3の長手方向に一対設けることもできるが、回転変位に対してより大きな抵抗力を与えるため、複数対設けることが好ましい。またそれに合わせて、対をなす突起付き凸面6及び突起付き凹面7も、基板2、3の長手方向に一対または複数対設けることができる。 A pair of facing protrusions 5 provided on the substrates 2 and 3 and forming a pair can be provided in the longitudinal direction of the substrates 2 and 3, but a plurality of pairs are provided in order to give a larger resistance force to the rotational displacement. Is preferable. Further, in accordance with this, a pair or a plurality of pairs of the convex surface 6 with protrusions and the concave surface 7 with protrusions forming a pair can be provided in the longitudinal direction of the substrates 2 and 3.

なお、二枚の基板2、3は、ここでは互いに異なる形状としたが、同一の形状とすることもできる。 Although the two substrates 2 and 3 have different shapes here, they may have the same shape.

ところで、基板2、3の各内側面Siには、その回転変位の回転支点となる支点凸部8及び支点凹部9が設けられ得る。ここでは、基板2、3に、図2、3及び6から解かるように、内側面Siから突出してその厚みが漸減する爪状の支点凸部8と、内側面Siから中空四角柱状に窪む支点凹部9とを、長手方向に複数対設けている。 By the way, each inner side surface Si of the substrates 2 and 3 may be provided with a fulcrum convex portion 8 and a fulcrum concave portion 9 which are rotational fulcrums of the rotational displacement. Here, as can be seen from FIGS. A plurality of pairs of fulcrum recesses 9 are provided in the longitudinal direction.

この実施形態では、リング部Rbの開閉操作を行うと、図6(a)~(c)に示すように、支点凸部8が支点凹部9内に入り込んだ状態で、支点凸部8と支点凹部9との接触箇所が回転支点となって、基板2、3の回転変位がもたらされる。 In this embodiment, when the ring portion Rb is opened and closed, the fulcrum convex portion 8 and the fulcrum are in a state where the fulcrum convex portion 8 is inserted into the fulcrum concave portion 9, as shown in FIGS. The contact point with the recess 9 serves as a rotation fulcrum, and rotational displacement of the substrates 2 and 3 is brought about.

先に述べた対向突起部5や突起付き凸面6及び突起付き凹面7は、図示のように、基板2、3の長手方向で、支点凸部8及び支点凹部9に隣接する位置に設けることが好ましい。支点凸部8及び支点凹部9の回転支点周りで基板2、3が回転変位するときに、その回転支点に隣接する対向突起部5で抵抗力が効果的に与えられ、回転変位の動作がより一層安定するからである。 As shown in the figure, the facing protrusion 5, the convex surface 6 with protrusions, and the concave surface 7 with protrusions described above may be provided at positions adjacent to the fulcrum convex portion 8 and the fulcrum concave portion 9 in the longitudinal direction of the substrates 2 and 3. preferable. When the substrates 2 and 3 are rotationally displaced around the rotational fulcrum of the fulcrum convex portion 8 and the fulcrum concave portion 9, resistance is effectively applied by the opposed protrusion 5 adjacent to the rotational fulcrum, and the rotational displacement operation is more effective. This is because it is more stable.

図7~11に、他の実施形態の綴じ具1が有する基板2、3を示す。図7~11の綴じ具1では、主として、爪状の支点凸部8及び中空四角柱状の支点凹部9の一部を、シャフト状の支点凸部18及びブッシュ状の支点凹部19に置き換えたことを除いて、先述した実施形態とほぼ同様の構成を有するものである。 7 to 11 show the substrates 2 and 3 included in the binding tool 1 of the other embodiment. In the binding tool 1 of FIGS. 7 to 11, mainly the claw-shaped fulcrum convex portion 8 and a part of the hollow square columnar fulcrum concave portion 9 are replaced with the shaft-shaped fulcrum convex portion 18 and the bush-shaped fulcrum concave portion 19. Except for the above-described embodiment, the configuration is almost the same as that of the above-described embodiment.

たとえば、周方向の一部で基板2、3に一体に形成されたシャフト状ないしロッド状の支点凸部18は、円筒の周方向の一部を除去した形状のブッシュ状の支点凹部19内に、基板2、3が回転変位できるように嵌め込まれている。基板2、3が回転変位するとき、ブッシュ状の支点凹部19内でシャフト状の支点凸部18が擦れながら回転する。 For example, the shaft-shaped or rod-shaped fulcrum convex portion 18 integrally formed with the substrate 2 and 3 in a part in the circumferential direction is formed in the bush-shaped fulcrum concave portion 19 having a shape in which a part in the circumferential direction is removed from the cylinder. , The substrates 2 and 3 are fitted so that they can be rotationally displaced. When the substrates 2 and 3 are rotationally displaced, the shaft-shaped fulcrum convex portion 18 rotates while rubbing in the bush-shaped fulcrum concave portion 19.

この綴じ具1では、シャフト状の支点凸部18がブッシュ状の支点凹部19内に保持されるので、基板2、3どうしを回転変位可能としつつも強固に連結することができる。それにより、綴じ具1の製造時における組立てに際し、基板2、3どうしの位置ずれが有効に抑制されて製造が容易になる。また、綴じ具1を組み立てた後の意図しない分解が防止される他、組立て後の寸法精度を大きく高めることができる。その上、この実施形態でも、対向突起部5や突起付き凸面6及び突起付き凹面7を設けたことにより、当該綴じ具1に綴じ込んだ紙葉の保持力が向上する。 In this binding tool 1, since the shaft-shaped fulcrum convex portion 18 is held in the bush-shaped fulcrum concave portion 19, the substrates 2 and 3 can be firmly connected to each other while being rotatable and displaceable. As a result, when assembling the binding tool 1 at the time of manufacturing, the misalignment between the substrates 2 and 3 is effectively suppressed, and the manufacturing becomes easy. In addition, unintentional disassembly after assembling the binding tool 1 can be prevented, and the dimensional accuracy after assembly can be greatly improved. Moreover, also in this embodiment, by providing the facing protrusion 5, the convex surface 6 with protrusions, and the concave surface 7 with protrusions, the holding power of the paper leaf bound to the binding tool 1 is improved.

突起付き凸面6や突起付き凹面7は、図9、10に示すように、基板2、3の長手方向で、シャフト状の支点凸部18又はブッシュ状の支点凹部19に隣接する位置で、さらにその両側に設けることが好適である。なお、図示の例では、支点凸部18の両側の突起付き凸面6及び、支点凹部19の両側の突起付き凹面7のそれぞれの長手方向外側に、突出部分11及び、それに対応する窪み部分12をそれぞれ設けている。 As shown in FIGS. It is preferable to provide it on both sides thereof. In the illustrated example, the protruding portion 11 and the corresponding recessed portion 12 are provided on the outer sides of the convex surface 6 with protrusions on both sides of the fulcrum convex portion 18 and the concave surface 7 with protrusions on both sides of the fulcrum concave portion 19 in the longitudinal direction. Each is provided.

なお、基板2、3のそれぞれの長手方向の両端部には、表面Sf側に互いに交差して延びる開閉操作部13を設けることができる。ユーザが開閉操作部13の先端部分を接近もしくは離隔させると、図5、6に示すように、基板2、3が回転支点周りに回転変位し、リング部Rbが開閉するよう操作することができる。 At both ends of the substrates 2 and 3 in the longitudinal direction, opening / closing operation portions 13 extending so as to intersect each other on the surface Sf side can be provided. When the user approaches or separates the tip portion of the opening / closing operation unit 13, as shown in FIGS. 5 and 6, the substrates 2 and 3 are rotationally displaced around the rotation fulcrum, and the ring portion Rb can be operated to open / close. ..

以上に述べた綴じ具1は、その構成部品である基板2、3及び弾性保持部材4の材質を、金属材料とすることも可能である。そのような金属製の綴じ具1であっても、この発明を適用することにより紙葉の保持力を高めることができる。 In the binding tool 1 described above, the materials of the substrates 2, 3 and the elastic holding member 4 which are the constituent parts thereof can be made of a metal material. Even with such a metal binding tool 1, the holding power of the paper leaf can be enhanced by applying the present invention.

他方、弾性保持部材4や基板2、3は、樹脂材料を含む材質からなるものとすることが好ましい。弾性保持部材4を樹脂含有材料の材質とすると、金属製のものに比して基板2、3の押付け力が低下する傾向があるところ、この発明を適用すれば、比較的多くの紙葉を有効に綴じ込むことができるようになる。この場合、弾性保持部材4及び基板2、3の材質は、樹脂材料のみとしてもよいが、さらに紙材料を含むものとしてもよい。 On the other hand, it is preferable that the elastic holding member 4 and the substrates 2 and 3 are made of a material including a resin material. When the elastic holding member 4 is made of a resin-containing material, the pressing force of the substrates 2 and 3 tends to be lower than that of a metal-made material. However, if this invention is applied, a relatively large number of paper sheets can be obtained. You will be able to bind effectively. In this case, the elastic holding member 4 and the substrates 2 and 3 may be made of only a resin material, or may further include a paper material.
