The present invention configures a binding tool (0) equipped with: a set of binding rod members (1, 2) that can pivot relative to each other via a hinge around the center axis thereof and that that open/close binding rods through the pivoting operation; and an operation member (3) that covers the shafts (13, 23) of the hinge, is able to slide along the direction of the center axis with respect to the binding rod members (1, 2), has a stopper that prohibits the binding rod members (1, 2) from pivoting in the direction that opens the binding rods, and can selectively assume a locked position, wherein the stopper contacts predetermined sections (14, 24) of the binding rod members (1, 2), and an unlocked position, wherein the stopper does not contact the predetermined sections (14, 24) even if the binding rod members (1, 2) are pivoted. As a result, the shafts (13, 23) of the hinge no longer impart a bumpy feel to a user.
Description
本発明は、紙葉類を綴じ止めるための綴じ具に関する。
The present invention relates to a binding tool for binding paper sheets.
ルーズリーフやクリアブックのリフィル等の紙葉類を綴じ止めることができるリング綴じ具（例えば、下記特許文献を参照）が既知である。この種の綴じ具は、環状をなす綴じ桿が回動動作によって開閉可能となっており、任意に紙葉類を差し替えることができる。
A ring binding tool (for example, see the following patent document) capable of binding paper sheets such as loose leaves and clear book refills is known. In this type of binding tool, an annular binding rod can be opened and closed by a rotating operation, and paper sheets can be arbitrarily replaced.
多くのリング綴じ具は、軸心方向に長尺な一組の綴じ桿部材をヒンジを介して連結し相対回動可能とした構造を有する。各綴じ桿部材は、部分円弧状をなす多数本の綴じ桿要素を支持している。そして、一方の綴じ桿部材に円筒状の軸受を軸心方向に沿って間欠的に設け、他方の綴じ桿にもやはり円筒状の軸受を軸心方向に沿って間欠的に設けて、両綴じ桿部材の軸受を（一方の軸受を他方の軸受間に位置づけて）同心軸上に配列した上、各軸受を貫く細棒を挿通してヒンジを構成している。
Many ring binding tools have a structure in which a pair of binding rod members elongated in the axial direction are connected via a hinge so as to be relatively rotatable. Each binding rod member supports a large number of binding rod elements having a partial arc shape. A cylindrical bearing is provided intermittently along the axial direction on one binding rod member, and a cylindrical bearing is also provided intermittently along the axial direction on the other binding rod, and both bindings are provided. The bearings of the flange members are arranged on concentric shafts (one bearing is positioned between the other bearings), and a thin rod passing through each bearing is inserted to constitute a hinge.
このようなものであると、綴じ桿部材の軸受の列が凸凹した感触をユーザに与えることになる。特に、中紙を綴じてリングノートとして使用する場合に、ノートの背側に軸受が露出し、その手触りが必ずしもよくない。
Such a thing gives the user a feeling that the row of bearings of the binding rod member is uneven. In particular, when the inner paper is bound and used as a ring notebook, the bearing is exposed on the back side of the notebook, and the touch is not always good.
本発明は、綴じ桿の開放状態と閉止状態との切り替えが容易で手触りもよい綴じ具を提供しようとするものである。
The present invention is intended to provide a binding tool that can be easily switched between an open state and a closed state of the binding rod and is easy to touch.
本発明では、ヒンジを介してその軸心周りに相対回動可能であり、回動動作を通じて綴じ桿を開閉させる一組の綴じ桿部材と、前記ヒンジの軸を覆うとともに前記綴じ桿部材に対し前記軸心方向に沿ってスライド可能であり、綴じ桿部材が前記綴じ桿を開放する方向に回動することを禁止するストッパを有し、当該ストッパが綴じ桿部材の所定部位に接触するロック位置と、綴じ桿部材を回動させても当該ストッパが綴じ桿部材の所定部位に接触しないアンロック位置とを選択的にとり得る操作部材とを具備する綴じ具を構成した。
In the present invention, a pair of binding rod members that are capable of relative rotation around the axis via a hinge and that open and close the binding rod through a rotation operation, and cover the shaft of the hinge and the binding rod member. A lock position that is slidable along the axial direction, has a stopper that prohibits the binding rod member from rotating in a direction to open the binding rod, and the stopper contacts a predetermined portion of the binding rod member And an operating member that can selectively take an unlock position where the stopper does not contact a predetermined portion of the binding rod member even when the binding rod member is rotated.
これにより、ヒンジの軸がユーザの手指に直接触れる機会が少なくなる。即ち、ヒンジの軸が凸凹した感触をユーザに与える可能性が小さくなる。その上で、操作部材を軸心方向にスライド操作することで、綴じ桿の開放状態と閉止状態との切り替えを行い得る。
This reduces the chance that the hinge axis will touch the user's fingers directly. That is, the possibility of giving the user a feeling that the axis of the hinge is uneven is reduced. Then, the operating member can be slid in the axial direction to switch the binding rod between the open state and the closed state.
より具体的には、前記ヒンジの軸が略円筒状の外周をなし、前記操作部材がこのヒンジの軸をくわえ込むようにヒンジの軸に係合する構成とする。
More specifically, the hinge shaft has a substantially cylindrical outer periphery, and the operation member engages with the hinge shaft so as to hold the hinge shaft.
前記一組の綴じ桿部材の各々に略円筒状の外周をなし前記ヒンジの軸となる軸体を設け、両者の軸体を直列に配置した状態で前記操作部材がこれらを相対回動可能に保持するものとすれば、両綴じ桿部材の軸体を貫く細棒が不要となる。
Each of the pair of binding rod members has a substantially cylindrical outer periphery and is provided with a shaft body that serves as a shaft of the hinge, and the operation member can be rotated relative to each other with the shaft bodies arranged in series. If it is to be held, a thin bar penetrating the shaft body of both binding rod members becomes unnecessary.
前記両軸体の互いに対向する端面の一方に凸部を形成し、他方にこの凸部を受け入れる凹部を形成して、これら凸部と凹部との係合構造を構成していれば、両綴じ桿部材の軸体の一体性が向上する。
If a convex portion is formed on one of the end surfaces facing each other of the shafts and a concave portion for receiving the convex portion is formed on the other, and an engagement structure between the convex portion and the concave portion is configured, both bindings are performed. The integrity of the shaft body of the flange member is improved.
前記操作部材が、並立する側壁と両側壁を連結する底壁とを備え、側壁及び底壁によって包囲される内部空間に前記ヒンジの軸を収容するものであり、前記側壁の端縁に切欠を形成し、切欠に隣接する部位を前記ストッパとして、前記操作部材が前記アンロック位置にあるときには前記綴じ桿部材の所定部位がこの切欠内に収まるようにすれば、綴じ桿部材及び操作部材によって綴じ具の基本構成が完結し、部品点数を削減することができる。
The operating member includes side walls that are arranged side by side and a bottom wall that connects both side walls, and the shaft of the hinge is accommodated in an inner space surrounded by the side walls and the bottom wall, and a notch is formed at an edge of the side wall. If a portion adjacent to the notch is used as the stopper and the predetermined portion of the binding rod member is accommodated in the notch when the operation member is in the unlocked position, the binding is performed by the binding rod member and the operation member. The basic structure of the tool is completed, and the number of parts can be reduced.
さらに、前記操作部材を前記アンロック位置から前記ロック位置に向けて変位させる方向に弾性付勢する弾性付勢部材を具備していれば、その弾性付勢力をも利用して綴じ桿の閉止状態を確実に保つことができ、綴じている紙葉類が不意に脱落するおそれが低減する。
Further, if the elastic biasing member that elastically biases the operation member in the direction of displacing from the unlock position toward the lock position is provided, the binding rod is also closed using the elastic biasing force. Can be reliably maintained, and the possibility that the bound paper sheets will fall off unexpectedly is reduced.
本発明によれば、綴じ桿の開放状態と閉止状態との切り替えが容易で手触りもよい好適な綴じ具を実現することができる。
According to the present invention, it is possible to realize a suitable binding tool that can be easily switched between an open state and a closed state of the binding rod and is easy to touch.

This ring notebook can be in a spread state where the page is opened at an angle of 180 °.
本実施形態の綴じ具０は、互いに相対的に回動する第一の綴じ桿部材１及び第二の綴じ桿部材２と、両綴じ桿部材１、２が支持する綴じ桿の開放状態／閉止状態を切り替えるために操作される操作部材３と、操作部材３を弾性付勢する弾性付勢部材たるコイルばね４とを構成部材とする。
The binding tool 0 of the present embodiment includes a first binding rod member 1 and a second binding rod member 2 that rotate relative to each other, and an open state / closed state of the binding rod supported by both binding rod members 1 and 2. The operating member 3 that is operated to switch the state and the coil spring 4 that is an elastic biasing member that elastically biases the operating member 3 are used as constituent members.
第一の綴じ桿部材１の形状と第二の綴じ桿部材２の形状とは相似している。第一の綴じ桿部材１は、軸心方向に対して平行に長尺な棒状の基体１１と、基体１１から伸び出した綴じ桿要素１２と、基体１１から離間し当該綴じ桿部材１の回転中心となる軸体１３と、この軸体１３を基体１１に連接する腕部１４とを備える。本実施形態では、これら基体１１、綴じ桿要素１２、軸体１３及び腕部１４を樹脂一体成形している。
The shape of the first binding rod member 1 and the shape of the second binding rod member 2 are similar. The first binding rod member 1 includes a rod-like base 11 that is long in parallel with the axial direction, a binding rod element 12 that extends from the base 11, and a rotation of the binding rod member 1 that is separated from the base 11. A shaft body 13 serving as a center and an arm portion 14 connecting the shaft body 13 to the base 11 are provided. In this embodiment, these base | substrate 11, the binding rod element 12, the shaft body 13, and the arm part 14 are integrally molded by resin.
綴じ桿要素１２は多数本存在し、それらが軸心方向に沿って立ち並んでいる。個々の綴じ桿要素１２は、基体１１の外側面１１２から軸心方向に対して垂直な外側方に一旦直進して突き出し、その外方端から円弧を描くように湾曲して立ち上がっている。綴じ桿要素１２の直進部分の上面は、基体１１の頂面１１３と略面一である。綴じ桿要素１２の湾曲部分の断面は、軸心方向に少しく拡張した扁平な形状、略長円状または略角丸四角状をなす。綴じ桿要素１２の先端部は、合决りの如く切り欠いてある。
A large number of binding rod elements 12 exist, and they are arranged along the axial direction. The individual binding rod elements 12 protrude straightly from the outer surface 112 of the base body 11 outward in the direction perpendicular to the axial direction, and are curved and rise from the outer end so as to draw an arc. The upper surface of the straight portion of the binding rod element 12 is substantially flush with the top surface 113 of the base body 11. The cross section of the curved portion of the binding rod element 12 has a flat shape slightly expanded in the axial direction, a substantially oval shape, or a substantially rounded square shape. The front end portion of the binding rod element 12 is notched like a joint.
軸体１３は、円筒状の外周をなし、軸心方向に沿って伸長している。軸体１３は複数（図示例では、綴じ桿要素１２の本数の約半数）存在し、それらが同心軸上に所定の間隙を隔てて並んでいる。軸体１３は、その軸心が基体１１の内側面１１１と略同一平面上にあるように、基体１１からやや内側方に偏倚している。
The shaft body 13 has a cylindrical outer periphery and extends along the axial direction. There are a plurality of shaft bodies 13 (in the example shown, about half the number of binding rod elements 12), which are arranged on a concentric shaft with a predetermined gap therebetween. The shaft body 13 is biased slightly inward from the base body 11 so that the axial center thereof is substantially flush with the inner surface 111 of the base body 11.
軸体１３の一端面には凹部１３１を、他端面には凸部１３２を、それぞれ形成している。凸部１３２は、軸体１３の軸心に重なる半球状の突起である。凹部１３１は、軸体１３の軸心位置から外側方に延びて軸体１３の外周にまで達した、即ち外側方に開口した凹溝であって、その内面は縦断面視（若しくは、外側面視）凸部１３２、２３２の径と同等の径の半円筒状をなしており、その溝幅も凸部１３２、２３２の径に略等しい。さらには、凹部１３１の内方端縁もまた、横断面視（若しくは、軸心方向から見て）凸部１３２、２３２の径と同等の径の半円弧状となっている。
A concave portion 131 is formed on one end surface of the shaft body 13, and a convex portion 132 is formed on the other end surface. The convex portion 132 is a hemispherical protrusion that overlaps the axial center of the shaft body 13. The concave portion 131 is a concave groove that extends outward from the axial center position of the shaft body 13 and reaches the outer periphery of the shaft body 13, i.e., opens outwardly. (View) It has a semi-cylindrical shape with a diameter equivalent to the diameter of the convex portions 132 and 232, and the groove width is substantially equal to the diameter of the convex portions 132 and 232. Furthermore, the inner end edge of the recess 131 is also in the shape of a semicircular arc having a diameter equivalent to the diameter of the protrusions 132 and 232 as viewed in cross section (or viewed from the axial direction).
腕部１４は、一つの軸体１３について二つ存在し、軸体１３の軸心方向に沿った両端部をそれぞれ基体１１に接合している。腕部１４における、基体１１の内側面１１１に連なる内方の側面１４１は、基体１１の内側面１１１に対して傾斜している。他方、腕部１４における、基体１１の外側面１１２に連なる外方の側面１４２は、基体１１の外側面１１２と略面一であるとともに、基体１１の底面１１４よりも若干突出するところまで垂下している。この腕部１４の外方の突出部１４３は、図５等に示しているように、軸心方向に沿った両端縁が外側面視Ｒをとったような曲面状となっている。
There are two arm portions 14 for one shaft body 13, and both end portions along the axial center direction of the shaft body 13 are joined to the base body 11. An inner side surface 141 that is continuous with the inner side surface 111 of the base body 11 in the arm portion 14 is inclined with respect to the inner side surface 111 of the base body 11. On the other hand, the outer side surface 142 of the arm portion 14 that is continuous with the outer surface 112 of the base body 11 is substantially flush with the outer surface 112 of the base body 11 and hangs down to a position that slightly protrudes from the bottom surface 114 of the base body 11. ing. As shown in FIG. 5 and the like, the projecting portion 143 on the outer side of the arm portion 14 has a curved surface shape in which both end edges along the axial direction take the outer side view R.
基体１１は、ちょうど角棒の内側面１１１と底面１１４とに跨るように、軸体１３の外周面に対向する部分円筒状の凹曲面１１５を成形した横断面形状を有している。この凹曲面１１５により、基体１１と軸体１３との狭間にある、腕部１４の対に挟まれた領域には、横断面視軸心回りの円環をなすようなスリット状の空隙１５が形成される。加えて、基体１１における、複数の軸体１３の間隙に臨む部位では、内側面１１１と凹曲面１１５とが交わる隅角を面取りしている。基体１１の外側面１１２と頂面１１３との隅角は、Ｒをとってある。
The base body 11 has a cross-sectional shape in which a partially cylindrical concave curved surface 115 facing the outer peripheral surface of the shaft body 13 is formed so as to straddle the inner surface 111 and the bottom surface 114 of the square bar. Due to the concave curved surface 115, a slit-like gap 15 that forms a ring around the axis of the transverse sectional view is formed in a region sandwiched between the pair of arm portions 14 between the base body 11 and the shaft body 13. It is formed. In addition, at the portion of the base 11 that faces the gap between the plurality of shaft bodies 13, the corner where the inner side surface 111 and the concave curved surface 115 intersect is chamfered. The corner angle between the outer surface 112 and the top surface 113 of the base 11 is R.
基体１１の内側面１１１と一端側の端面との隅角は、軸心方向に対し交差する傾斜面１１６となるように切り落とした形状としている。
The corner angle between the inner surface 111 of the base 11 and the end surface on one end side is cut off so as to be an inclined surface 116 that intersects the axial direction.
第二の綴じ桿部材２は、第一の綴じ桿部材１側の基体１１と同等に長尺な棒状の基体２１と、基体２１から伸び出した綴じ桿要素２２と、基体２１から離間し当該綴じ桿部材２の回転中心となる軸体２３と、この軸体２３を基体２１に連接する腕部２４とを備える。そして、やはりこれら基体２１、綴じ桿要素２２、軸体２３及び腕部２４を樹脂一体成形している。
The second binding rod member 2 has a bar-like base 21 that is as long as the base 11 on the first binding rod member 1 side, a binding rod element 22 that extends from the base 21, and the base 21 that is separated from the base 21. A shaft body 23 serving as a rotation center of the binding rod member 2 and an arm portion 24 connecting the shaft body 23 to the base body 21 are provided. The base body 21, the binding rod element 22, the shaft body 23, and the arm portion 24 are also integrally molded with resin.
綴じ桿要素２２は、第一の綴じ桿部材１側の綴じ桿要素１２と対をなして環状の綴じ桿を構成する。各綴じ桿要素２２は、基体２１の外側面２１２から軸心方向に対して垂直な外側方に一旦直進して突き出し、その外方端から円弧を描くように湾曲して立ち上がっている。綴じ桿要素２２の直進部分の上面は、基体２１の頂面２１３と略面一である。綴じ桿要素２２の湾曲部分の断面は、軸心方向に少しく拡張した扁平な形状、略長円状または略角丸四角状をなす。綴じ桿要素２２の先端部は、合决りの如く切り欠いてある。
The binding rod element 22 is paired with the binding rod element 12 on the first binding rod member 1 side to form an annular binding rod. Each binding rod element 22 protrudes from the outer surface 212 of the base body 21 by going straight outward in a direction perpendicular to the axial direction, and is curved and rises so as to draw an arc from its outer end. The upper surface of the straight portion of the binding rod element 22 is substantially flush with the top surface 213 of the base body 21. The cross section of the curved portion of the binding rod element 22 has a flat shape slightly expanded in the axial direction, a substantially oval shape, or a substantially rounded square shape. The front end portion of the binding rod element 22 is notched like a joint.
軸体２３は、第一の綴じ桿部材１側の軸体１３と略同径の円筒状の外周をなし、軸心方向に沿って伸長している。軸体２３は複数存在し、それらが同心軸上に所定の間隙を隔てて並んでいる。これら軸体２３は、第一の綴じ桿部材１側の複数の軸体１３の間隙に収まるように配設してある。第二の綴じ桿部材２側の軸体２３の軸心方向寸法は第一の綴じ桿部材１側の軸体１３の間隙のそれに略等しく、第一の綴じ桿部材１側の軸体１３の軸心方向寸法は第二の綴じ桿部材２側の軸体２３の間隙のそれに略等しい。軸体２３は、その軸心が基体２１の内側面２１１と略同一平面上にあるように、基体２１からやや内側方に偏倚している。
The shaft body 23 has a cylindrical outer periphery substantially the same diameter as the shaft body 13 on the first binding rod member 1 side, and extends along the axial direction. A plurality of shaft bodies 23 exist, and they are arranged on a concentric shaft with a predetermined gap therebetween. These shaft bodies 23 are disposed so as to fit in the gaps between the plurality of shaft bodies 13 on the first binding rod member 1 side. The axial center direction dimension of the shaft body 23 on the second binding rod member 2 side is substantially equal to the gap of the shaft body 13 on the first binding rod member 1 side, and the shaft body 13 on the first binding rod member 1 side has the same dimension. The axial direction dimension is substantially equal to that of the gap of the shaft body 23 on the second binding rod member 2 side. The shaft body 23 is slightly inwardly biased from the base body 21 so that the axial center thereof is substantially on the same plane as the inner side surface 211 of the base body 21.
軸体２３の一端面には凹部２３１を、他端面には凸部２３２を、それぞれ形成している。凹部２３１は、第一の綴じ桿部材１側の軸体１３の凸部１３２を収容する。逆に、凸部２３２は、第一の綴じ桿部材１側の軸体１３の凹部１３１に挿入する。凸部２３２は、軸体２３の軸心に重なる半球状の突起である。凹部２３１は、軸体２３の軸心位置から外側方に延びて軸体２３の外周にまで達した凹溝であって、その内面は縦断面視凸部１３２、２３２の径と同等の径の半円筒状をなしており、その溝幅も凸部１３２、２３２の径に略等しい。さらに、凹部２３１の内方端縁もまた、横断面視凸部１３２、２３２の径と同等の径の半円弧状となっている。
A concave portion 231 is formed on one end surface of the shaft body 23, and a convex portion 232 is formed on the other end surface. The concave portion 231 accommodates the convex portion 132 of the shaft body 13 on the first binding rod member 1 side. Conversely, the convex portion 232 is inserted into the concave portion 131 of the shaft body 13 on the first binding rod member 1 side. The convex portion 232 is a hemispherical protrusion that overlaps the axial center of the shaft body 23. The concave portion 231 is a concave groove extending outward from the axial center position of the shaft body 23 and reaching the outer periphery of the shaft body 23, and the inner surface thereof has a diameter equivalent to the diameter of the convex sections 132 and 232 in the longitudinal section. It has a semi-cylindrical shape, and the groove width is substantially equal to the diameter of the convex portions 132 and 232. Further, the inner end edge of the recess 231 is also a semicircular arc having a diameter equivalent to the diameter of the protrusions 132 and 232 in cross section.
腕部２４は、軸体２３の軸心方向に沿った両端部をそれぞれ基体２１に接合している。腕部２４における、基体２１の内側面２１１に連なる内方の側面２４１は、基体２１の内側面２１１に対して傾斜している。他方、腕部２４における、基体２１の外側面２１２に連なる外方の側面２４２は、基体２１の外側面２１２と略面一であるとともに、基体２１の底面２１４よりも若干突出するところまで垂下している。この腕部２４の外方の突出部２４３は、図８等に示しているように、軸心方向に沿った両端縁が外側面視Ｒをとったような曲面状となっている。
The arm portion 24 has both end portions along the axial direction of the shaft body 23 joined to the base body 21. An inner side surface 241 that is continuous with the inner side surface 211 of the base body 21 in the arm portion 24 is inclined with respect to the inner side surface 211 of the base body 21. On the other hand, the outer side surface 242 of the arm portion 24 that is continuous with the outer surface 212 of the base body 21 is substantially flush with the outer surface 212 of the base body 21 and hangs down to a position that slightly protrudes from the bottom surface 214 of the base body 21. ing. As shown in FIG. 8 and the like, the projecting portion 243 on the outer side of the arm portion 24 has a curved shape in which both end edges along the axial direction take the outer side view R.
基体２１は、ちょうど角棒の内側面２１１と底面２１４とに跨るように、軸体２３の外周面に対向する部分円筒状の凹曲面２１５を成形した横断面形状を有している。この凹曲面２１５により、基体２１と軸体２３との狭間にある、腕部２４の対に挟まれた領域には、横断面視軸心回りの円環をなすようなスリット状の空隙２５が形成される。加えて、基体２１における、複数の軸体２３の間隙に臨む部位では、内側面２１１と凹曲面２１５とが交わる隅角を面取りしている。基体２１の外側面２１２と頂面２１３との隅角は、Ｒをとってある。
The base body 21 has a cross-sectional shape in which a partially cylindrical concave curved surface 215 facing the outer peripheral surface of the shaft body 23 is formed so as to straddle the inner surface 211 and the bottom surface 214 of the square bar. Due to the concave curved surface 215, a slit-like gap 25 that forms a ring around the axis of the transverse sectional view is formed in a region between the pair of arm portions 24 between the base 21 and the shaft body 23. It is formed. In addition, at the portion of the base 21 that faces the gap between the plurality of shaft bodies 23, the corner where the inner side surface 211 and the concave curved surface 215 intersect is chamfered. The corner angle between the outer surface 212 and the top surface 213 of the base body 21 is R.
基体２１の内側面２１１と一端側の端面との隅角は、軸心方向に対し交差する傾斜面２１６となるように切り落とした形状としている。
The corner angle between the inner surface 211 of the substrate 21 and the end surface on one end side is cut off so as to be an inclined surface 216 that intersects the axial direction.
また、第二の綴じ桿部材２の基体２１の他端近傍に、フック２６を設けている。フック２６は、コイルばね４の一端を支持するためのもので、基体２１の底面２１４から突出している。
Further, a hook 26 is provided in the vicinity of the other end of the base 21 of the second binding rod member 2. The hook 26 is for supporting one end of the coil spring 4 and protrudes from the bottom surface 214 of the base body 21.
操作部材３は、軸心方向に対して平行に延伸し並立した側壁３１、３２と、両側壁３１、３２を連結する底壁３３とを備える。本実施形態では、これら側壁３１、３２及び底壁３３を樹脂一体成形しており、側壁３１、３２と底壁３３とで略Ｃ字またはＵ字管状の周壁を形作っている。操作部材３の全長は、綴じ桿部材１、２の基体１１、２１のそれよりも大きい。
The operation member 3 includes side walls 31 and 32 extending parallel to the axial direction and side walls 31 and 32, and bottom walls 33 connecting both side walls 31 and 32. In the present embodiment, the side walls 31 and 32 and the bottom wall 33 are integrally formed with resin, and the side walls 31 and 32 and the bottom wall 33 form a substantially C-shaped or U-shaped peripheral wall. The total length of the operation member 3 is larger than that of the base bodies 11 and 21 of the binding rod members 1 and 2.
各側壁３１、３２の上端縁には、複数箇所に切欠３１１、３２１を形成してある。一方側の側壁３１の切欠３１１の数は第一の綴じ桿部材１の腕部１４の数と同じであり、他方側の側壁３２の切欠３２１の数は第二の綴じ桿部材２の腕部２４の数と同じである。また、一方側の側壁３１の切欠３１１の位置は第一の綴じ桿部材１の腕部１４の配置に対応しており、他方側の側壁３２の切欠３２１の位置は第二の綴じ桿部材２の腕部２４の配置に対応している。それ故、切欠３１１と切欠３２１とは、軸心方向にずれている。切欠３１１、３２１の軸心方向に沿った開口幅寸法は、腕部１４、２４の軸心方向寸法よりも多少大きい。切欠３１１、３２１の下端は、側壁３１、３２の内側面近傍を除き、外側方に向かうほど下方に落ち込む傾斜端面であり、側壁の内側面近傍においてのみ上向面となっている。
Notches 311 and 321 are formed at a plurality of locations on the upper edge of each side wall 31 and 32. The number of notches 311 on the side wall 31 on one side is the same as the number of arm portions 14 of the first binding rod member 1, and the number of notches 321 on the side wall 32 on the other side is the arm portion of the second binding rod member 2. It is the same as the number of 24. The position of the notch 311 on the side wall 31 on one side corresponds to the position of the arm portion 14 of the first binding rod member 1, and the position of the notch 321 on the side wall 32 on the other side corresponds to the second binding rod member 2. This corresponds to the arrangement of the arm portions 24. Therefore, the notch 311 and the notch 321 are shifted in the axial direction. The opening width dimension along the axial direction of the notches 311 and 321 is slightly larger than the axial dimension of the arm portions 14 and 24. The lower ends of the cutouts 311 and 321 are inclined end surfaces that fall downward toward the outer side except for the vicinity of the inner side surfaces of the side walls 31 and 32, and are upward only in the vicinity of the inner side surfaces of the side walls.
さらに、両側壁３１、３２における、切欠３１１、３２１の形成箇所から軸心方向に偏倚した場所に、突起３１２、３２２を設けている。突起３１２、３２２は、側壁３１、３２の内側面から内側方に対をなして突出している。
Furthermore, the projections 312 and 322 are provided at the positions deviated in the axial direction from the positions where the notches 311 and 321 are formed on both side walls 31 and 32. The protrusions 312 and 322 protrude in pairs from the inner side surfaces of the side walls 31 and 32 inward.
両側壁３１、３２の内法は、綴じ桿部材１、２の軸体１３、２３の径に略等しい。また、底壁３３は、軸体１３、２３の径に略等しい内径を有する略部分円筒となっている。因みに、底壁３３における、突起３１２、３２２の直下に穿たれている貫通孔３３１は、突起３１２、３２２を成形するための型抜き用の孔である。
The inner method of the side walls 31 and 32 is substantially equal to the diameter of the shafts 13 and 23 of the binding rod members 1 and 2. The bottom wall 33 is a substantially partial cylinder having an inner diameter substantially equal to the diameter of the shaft bodies 13 and 23. Incidentally, the through-hole 331 formed in the bottom wall 33 immediately below the protrusions 312 and 322 is a die-cutting hole for forming the protrusions 312 and 322.
操作部材３の周壁３１、３２、３３によって包囲された内部空間は、操作部材３の軸心方向に沿った両端部にて閉塞されている。操作部材３の一端は、ユーザがこれを把持するための把手３４となる。そして、この把手３４に隣接する位置に、拡開部３５を設けている。拡開部３５は、操作部材３の他端に向かって延びるブロック状の部位で、その先端側に平面視くさび形をなすように両外側方を向いた傾斜面３５１、３５２を形成してある。拡開部３５の傾斜面３５１、３５２は、それぞれが軸心方向に対して交差しており、両綴じ桿部材１、２の基体１１、２１の一端に形成した各傾斜面１１６、２１６に略平行である。操作部材３の拡開部３５と両綴じ桿部材１、２の基体１１、２１の一端とは、後述する操作力変換機構を構成する。
The internal space surrounded by the peripheral walls 31, 32, 33 of the operation member 3 is closed at both ends along the axial direction of the operation member 3. One end of the operation member 3 serves as a handle 34 for the user to hold it. An expanding portion 35 is provided at a position adjacent to the handle 34. The expanding portion 35 is a block-like portion extending toward the other end of the operation member 3, and inclined surfaces 351, 352 facing both outer sides are formed on the tip side so as to form a wedge shape in plan view. . The inclined surfaces 351 and 352 of the expanding portion 35 intersect with each other with respect to the axial direction, and are substantially similar to the inclined surfaces 116 and 216 formed at one end of the bases 11 and 21 of the binding rod members 1 and 2. Parallel. The expanding portion 35 of the operation member 3 and one ends of the base bodies 11 and 21 of the binding binding members 1 and 2 constitute an operation force conversion mechanism described later.
また、操作部材３の他端近傍に、フック３６を設けている。フック３６は、コイルばね４の他端を支持するためのもので、第二の綴じ桿部材２に設けたフック２６と軸心方向に沿って対向する。
Further, a hook 36 is provided in the vicinity of the other end of the operation member 3. The hook 36 is for supporting the other end of the coil spring 4 and faces the hook 26 provided on the second binding rod member 2 along the axial direction.
本実施形態の綴じ具０を組み立てるにあたっては、まず、第一の綴じ桿部材１の基体１１の内側面１１１と第二の綴じ桿部材２の基体２１の内側面２１１とを当接ないし近接させ、第一の綴じ桿部材１の軸体１３と第二の綴じ桿部材２の軸体２３とを同心軸上に配置する。軸体１３の凸部１３２は軸体２３の凹部２３１内に挿入し、軸体２３の凸部２３２は軸体１３の凹部１３１内に挿入する。両綴じ桿部材１、２の軸体１３、２３は、互いに密接ないし近接して交互に並ぶ様相となる。
In assembling the binding tool 0 of the present embodiment, first, the inner surface 111 of the base 11 of the first binding rod member 1 and the inner surface 211 of the base 21 of the second binding rod member 2 are brought into contact with or close to each other. The shaft body 13 of the first binding rod member 1 and the shaft body 23 of the second binding rod member 2 are arranged on a concentric axis. The convex portion 132 of the shaft body 13 is inserted into the concave portion 231 of the shaft body 23, and the convex portion 232 of the shaft body 23 is inserted into the concave portion 131 of the shaft body 13. The shaft bodies 13 and 23 of the both binding rod members 1 and 2 are arranged in an alternating manner in close proximity to each other or close to each other.
そして、両綴じ桿部材１、２の軸体１３、２３をくわえ込むように操作部材３を組み付ける。即ち、操作部材３の側壁３１、３２及び底壁３３に包囲された内部空間に、両綴じ桿部材１、２の軸体１３、２３を嵌め入れる。これにより、各綴じ桿部材１、２が、軸体１３、２３を回転軸として回動することが可能となる。なおかつ、操作部材３が、軸体１３、２３に沿って軸心方向にスライド移動することが可能となる。操作部材３の側壁３１、３２の内面の突起３１２、３２２は、綴じ桿部材１、２の軸体１３、２３に係合し、軸体１３、２３が操作部材３から脱出することを抑止する。綴じ桿部材１、２の軸体１３、２３は、操作部材３によって被覆される。
Then, the operation member 3 is assembled so that the shaft bodies 13 and 23 of the both binding rod members 1 and 2 are inserted. That is, the shaft bodies 13 and 23 of both binding rod members 1 and 2 are fitted into the internal space surrounded by the side walls 31 and 32 and the bottom wall 33 of the operation member 3. As a result, the binding rod members 1 and 2 can rotate about the shaft bodies 13 and 23 as rotation axes. In addition, the operation member 3 can slide along the shaft bodies 13 and 23 in the axial direction. The protrusions 312 and 322 on the inner surfaces of the side walls 31 and 32 of the operation member 3 engage with the shaft bodies 13 and 23 of the binding rod members 1 and 2, and prevent the shaft bodies 13 and 23 from escaping from the operation member 3. . The shaft bodies 13 and 23 of the binding rod members 1 and 2 are covered with the operation member 3.
なお、予め、第二の綴じ桿部材２に設けたフック２６と操作部材３に設けたフック３６とに、コイルばね４の両端をそれぞれ掛け止めておく。綴じ桿部材１、２の軸体１３、２３を操作部材３に嵌め入れることで、操作部材３に設けたフック３６は、第二の綴じ桿部材２に設けたフック２６よりもさらに他端側に位置づけられる。
It should be noted that both ends of the coil spring 4 are respectively hooked on the hook 26 provided on the second binding rod member 2 and the hook 36 provided on the operation member 3 in advance. By fitting the shafts 13 and 23 of the binding rod members 1 and 2 into the operation member 3, the hook 36 provided on the operation member 3 is further on the other end side than the hook 26 provided on the second binding rod member 2. Is positioned.
第一の綴じ桿部材１と第二の綴じ桿部材２とは、軸体１３、２３の軸心周りに相対的に回動する。その回動動作を通じて、綴じ桿要素１２と綴じ桿要素２２とで構成する環状の綴じ桿を開閉することができる。図６、図１０等に示すように、綴じ桿を閉じた状態では、一方側の綴じ桿要素１２の先端部と他方側の綴じ桿要素２２の先端部とが合决り構造の如く軸心方向に重なり合い、綴じ桿に綴じ止めている紙葉類Ｓの抜出を阻止する。図７、図１１等に示すように、綴じ桿を開いた状態では、両綴じ桿要素１２、２２の先端部同士が離反して、紙葉類Ｓの抜出を許容する。
The first binding rod member 1 and the second binding rod member 2 rotate relatively around the shaft centers of the shaft bodies 13 and 23. Through the turning operation, the annular binding rod constituted by the binding rod element 12 and the binding rod element 22 can be opened and closed. As shown in FIGS. 6 and 10 and the like, when the binding rod is closed, the tip of the binding rod element 12 on one side and the tip of the binding rod element 22 on the other side are axially aligned like a joint structure. The paper sheets S that overlap in the direction and are bound to the binding rod are prevented from being pulled out. As shown in FIGS. 7, 11, etc., in a state where the binding rod is opened, the leading ends of both binding rod elements 12, 22 are separated from each other, and the paper sheet S is allowed to be extracted.
操作部材３は、綴じ桿部材１、２に対して軸心方向に相対変位し、図１０に示すロック位置と、図１１に示すアンロック位置とを選択的にとり得る。操作部材３がロック位置にあるとき、一方側の側壁３１に形成している切欠３１１は同じ側の綴じ桿部材１の腕部１４に対して軸心方向にずれており、他方側の側壁３２に形成している切欠３２１も同じ側の綴じ桿部材２の腕部２４に対して軸心方向にずれている。そのため、図１２ないし図１５に示しているように、両綴じ桿部材１、２を綴じ桿を開放する方向に回動させようとしても、腕部１４、２４が操作部材３の側壁３１、３２の端縁に衝突してしまい、回動させることができない。換言すれば、操作部材３の側壁３１、３２における切り欠かれていない端縁がストッパとなって、綴じ桿を開放することを禁止する。
The operation member 3 is relatively displaced in the axial direction with respect to the binding rod members 1 and 2, and can selectively take the lock position shown in FIG. 10 and the unlock position shown in FIG. When the operation member 3 is in the locked position, the notch 311 formed in the side wall 31 on one side is displaced in the axial direction with respect to the arm portion 14 of the binding rod member 1 on the same side, and the side wall 32 on the other side. The notch 321 formed in the above is also displaced in the axial direction with respect to the arm portion 24 of the binding rod member 2 on the same side. Therefore, as shown in FIGS. 12 to 15, even if both the binding rod members 1, 2 are rotated in the direction to open the binding rod, the arm portions 14, 24 remain on the side walls 31, 32 of the operation member 3. It will collide with the edge of this and cannot be rotated. In other words, the uncut end edges of the side walls 31 and 32 of the operation member 3 serve as stoppers and prohibit the opening of the binding rod.
また、このとき、第一の綴じ桿部材１の基体１１と、第二の綴じ桿部材２の基体２１とは、その内側面１１１、２１１同士が当接ないし近接した状態となる。操作部材３の一端側に設けた拡開部３５は、両綴じ桿部材１、２の基体１１、２１の一端に（近接はしているものの）必ずしも接触していない。操作部材３に設けたフック３６は、第二の綴じ桿部材２に設けたフック２６に比較的近い位置にあり、両フック２６、３６に掛けているコイルばね４は張力を発揮しない。
Further, at this time, the base 11 of the first binding rod member 1 and the base 21 of the second binding rod member 2 are in a state in which the inner side surfaces 111 and 211 are in contact with or close to each other. The expanding portion 35 provided on one end side of the operation member 3 does not necessarily contact one end of the base bodies 11 and 21 of the binding binding members 1 and 2 (although they are close to each other). The hook 36 provided on the operation member 3 is located relatively close to the hook 26 provided on the second binding rod member 2, and the coil spring 4 hung on both the hooks 26 and 36 does not exert tension.
翻って、操作部材３をロック位置からアンロック位置に向けてスライド移動させると、一方側の側壁３１に形成している切欠３１１の軸心方向に沿った位置が同じ側の綴じ桿部材１の腕部１４に合致し、また他方側の側壁３２に形成している切欠３２１の軸心方向に沿った位置も同じ側の綴じ桿部材２の腕部２４に合致する。従って、腕部１４、２４が切欠３１１、３２１内に進入できるようになる。のみならず、同一の軸部１３１、２３に連接する腕部１４、２４の対に挟まれた空隙１５、２５に、操作部材３の側壁３１、３２における、切欠３１１、３２１の対に挟まれた部位が進入できるようにもなる。結果として、図１６ないし図１９に示すように、両綴じ桿部材１、２を相対回動させて綴じ桿を開放することが許容されることとなる。
In turn, when the operating member 3 is slid from the locked position toward the unlocked position, the position along the axial direction of the notch 311 formed in the side wall 31 on one side is the same as that of the binding rod member 1 on the same side. The position along the axial direction of the notch 321 formed in the side wall 32 on the other side also matches the arm portion 24 of the binding rod member 2 on the same side. Accordingly, the arm portions 14 and 24 can enter the notches 311 and 321. In addition, the gaps 15 and 25 sandwiched between the pair of arms 14 and 24 connected to the same shaft portions 131 and 23 are sandwiched between the pair of notches 311 and 321 in the side walls 31 and 32 of the operation member 3. You can also enter the part. As a result, as shown in FIGS. 16 to 19, it is allowed to open the binding rod by relatively rotating both the binding rod members 1 and 2.
同時に、操作部材３がロック位置からアンロック位置へと変位する過程で、操作部材３の一端側に設けた拡開部３５の傾斜面３５１、３５２が、両綴じ桿部材１、２の基体１１、２１の一端に形成している傾斜面１１６、２１６に接触し、さらにはこれら基体１１、２１を互いに離反する方向に押し広げる。最終的に、操作部材３の拡開部３５は両綴じ桿部材１、２の基体１１、２１の内側面１１１、２１１間に入り込む。つまり、拡開部３５と基体１１、２１の一端とが操作力変換機構として働き、操作部材３を軸心方向にスライドさせる操作力を、綴じ桿部材１、２を綴じ桿が開放する方向に回動させる力に変換する。
At the same time, in the process in which the operating member 3 is displaced from the locked position to the unlocked position, the inclined surfaces 351 and 352 of the expanding portion 35 provided on one end side of the operating member 3 cause the bases 11 of both binding rod members 1 and 2. , 21 is in contact with the inclined surfaces 116, 216 formed at one end of the substrate 21, and further, the base members 11, 21 are pushed away from each other. Finally, the expanded portion 35 of the operation member 3 enters between the inner side surfaces 111 and 211 of the base bodies 11 and 21 of both binding rod members 1 and 2. That is, the expanding portion 35 and one end of the bases 11 and 21 function as an operating force conversion mechanism, and the operating force that slides the operating member 3 in the axial direction is set in the direction in which the binding rod members 1 and 2 open the binding rod. Convert to turning force.
総じて言えば、操作部材３をロック位置からアンロック位置へと変位させることで、ストッパが両綴じ桿部材１、２の腕部１４、２４から軸心方向に沿って退避しつつ、拡開部３５が両綴じ桿部材１、２を押し広げて綴じ桿を開放させる。また、操作部材３の変位により、操作部材３に設けたフック３６が第二の綴じ桿部材２に設けたフック２６から遠ざかるため、両フック２６、３６に掛けているコイルばね４が引き伸ばされて張力を発揮するようになる。
Generally speaking, by displacing the operating member 3 from the locked position to the unlocked position, the stopper is retracted from the arms 14 and 24 of the binding binding members 1 and 2 along the axial direction, while the expansion portion 35 spreads both the binding rod members 1 and 2 and opens the binding rod. Further, since the hook 36 provided on the operation member 3 moves away from the hook 26 provided on the second binding rod member 2 due to the displacement of the operation member 3, the coil spring 4 hung on both the hooks 26, 36 is stretched. Demonstrate tension.
綴じ桿を開放している間は、操作部材３をアンロック位置からロック位置に向けて変位させる方向の弾性付勢力、即ちコイルばね４の引っ張り張力が働くが、綴じ桿部材１、２の腕部１４、２４が側壁３１、３２の切欠３１１、３２１の開口縁に係合することから、操作部材３はアンロック位置に維持される。この状態で、ユーザが両綴じ桿要素１２、２２を手指で摘んで閉じる操作を行うと、綴じ桿部材１、２が互いに相寄る方向に回動し、各腕部１４、２４が操作部材３の側壁３１、３２の切欠３１１、３２１から脱出する。従って、操作部材３がロック位置に復帰することが許容される。
While the binding rod is opened, an elastic urging force in a direction to displace the operation member 3 from the unlocked position toward the locked position, that is, the tensile tension of the coil spring 4, works. Since the portions 14 and 24 engage with the opening edges of the notches 311 and 321 of the side walls 31 and 32, the operation member 3 is maintained in the unlocked position. In this state, when the user performs an operation of gripping and closing the binding rod elements 12 and 22 with fingers, the binding rod members 1 and 2 rotate in a direction in which the binding rod members 1 and 2 are close to each other. It escapes from the notches 311 and 321 of the side walls 31 and 32. Therefore, the operation member 3 is allowed to return to the lock position.
綴じ桿部材１、２の基体１１、２２は長尺であるので、多数本存在する綴じ桿の一部を摘んで閉じようとしても、当該部位と他の部位との間でねじれを生じ、綴じ桿部材１、２全体が綴じ桿を閉じる方向に回動しないおそれがある。しかしながら、弾性付勢されている操作部材３がロック位置に向けて変位しようとし、その力が側壁３１、３２の切欠３１１、３２１の開口縁を介して綴じ桿部材１、２の腕部１４、２４を内側方に押し戻そうとするため、基体１１、２１のねじれが抑制され、綴じ桿部材１、２全体が回動して全ての綴じ桿を一斉に閉じることができる。
Since the bases 11 and 22 of the binding rod members 1 and 2 are long, even if a portion of a large number of binding rods are picked up and closed, twisting occurs between the portion and other portions, and the binding is performed. There is a possibility that the entire scissors members 1 and 2 may not rotate in the direction of closing the binding scissors. However, the operation member 3 that is elastically biased tends to be displaced toward the lock position, and the force is applied to the arm portions 14 of the binding rod members 1 and 2 through the opening edges of the notches 311 and 321 of the side walls 31 and 32. Since it is going to push 24 back inward, the twist of the base | substrates 11 and 21 is suppressed, the binding hook members 1 and 2 whole rotate, and all the binding hooks can be closed simultaneously.
本実施形態によれば、所定の軸心周りに相対回動可能であり、その回動動作を通じて綴じ桿を開閉させる一組の綴じ桿部材１、２と、前記綴じ桿部材１、２に対して相対変位可能であり、綴じ桿部材１、２が前記綴じ桿を開放する方向に回動することを禁止するロック位置とこれを許容するアンロック位置とを選択的にとり得る操作部材３と、前記綴じ桿部材１、２と前記操作部材３との間に介在し、前記操作部材３を前記ロック位置から前記アンロック位置に向けて変位させる操作力を、前記綴じ桿部材を前記綴じ桿が開放する方向に回動させる力に変換する操作力変換機構とを具備する綴じ具０を構成したため、操作部材３をアンロック位置に変位させる操作によって綴じ桿を開かせることができる。従って、綴じ桿が多数本存在していたとしても、それらを一斉に開放する操作が容易であって利便性が高い。
According to this embodiment, a pair of binding rod members 1 and 2 that are capable of relative rotation around a predetermined axis and that open and close the binding rod through the rotation operation, and the binding rod members 1 and 2 An operation member 3 that is capable of relative displacement, and that can selectively take a lock position that prohibits the binding rod members 1 and 2 from rotating in a direction to open the binding rod and an unlock position that allows the binding rod; The binding rod member is interposed between the binding rod members 1 and 2 and the operation member 3, and an operation force for displacing the operation member 3 from the locked position toward the unlocked position is indicated by the binding rod member. Since the binding tool 0 including the operation force conversion mechanism that converts the force to rotate in the opening direction is configured, the binding rod can be opened by an operation of displacing the operation member 3 to the unlock position. Therefore, even if there are a large number of binding folds, the operation of opening them all at once is easy and highly convenient.
前記操作部材３が前記ロック位置から前記アンロック位置へと変位する過程で前記両綴じ桿部材１、２間に差し入って両者の間を押し広げる拡開部３５を操作部材３に設けており、この拡開部３５を要素として前記操作力変換機構を構成しているため、部品点数が徒に増加せず、コスト面で有利となる。
The operation member 3 is provided with an expanding portion 35 that is inserted between the binding rod members 1 and 2 and pushes between them in the process in which the operation member 3 is displaced from the locked position to the unlocked position. Since the operating force conversion mechanism is configured with the expanded portion 35 as an element, the number of parts does not increase easily, which is advantageous in terms of cost.
前記操作部材３は、前記軸心方向に沿ってスライド可能であり、前記拡開部３５は、操作部材３のスライド方向に対して交差する傾斜面３５１、３５２を有し、この傾斜面３５１、３５２を介して前記綴じ桿部材１、２に当接して両綴じ桿部材１、２間を押し広げるものであるため、シンプルな構造となり、故障のリスクも小さくなる。
The operating member 3 is slidable along the axial direction, and the expanding portion 35 has inclined surfaces 351 and 352 that intersect the sliding direction of the operating member 3, and the inclined surface 351, Since it is in contact with the binding rod members 1 and 2 via 352 and pushes between the binding rod members 1 and 2, the structure is simple and the risk of failure is reduced.
前記綴じ桿部材１、２は、前記軸心方向に沿って延伸し、同方向に沿って複数本の綴じ桿を並べて設けたものであり、前記拡開部３５は、前記綴じ桿部材１、２の一端側から両綴じ桿部材１、２間に差し入るものであるため、操作力変換機構を綴じ具０の中間部ではなく端部に配することができる。よって、綴じ具０の組立作業が難化しない。
The binding rod members 1 and 2 extend along the axial direction and are provided with a plurality of binding rods arranged along the same direction, and the expanding portion 35 includes the binding rod member 1, 2 is inserted between the two binding rod members 1 and 2 from one end side, the operating force conversion mechanism can be arranged not at the middle portion of the binding tool 0 but at the end portion. Therefore, the assembly work of the binding tool 0 does not become difficult.
前記操作部材３を前記アンロック位置から前記ロック位置に向けて変位させる方向に弾性付勢する弾性付勢部材４を具備しているため、綴じ桿を閉じる回動方向に弾性付勢するばね等が不要である。当該弾性付勢部材４の綴じ桿部材の配置の自由度も高い。
Since the elastic urging member 4 that elastically urges the operation member 3 in the direction to displace the operation member 3 from the unlock position toward the lock position is provided, a spring that elastically urges the binding rod in the turning direction to close the binding rod. Is unnecessary. The degree of freedom of arrangement of the binding rod member of the elastic biasing member 4 is also high.
前記綴じ桿部材１、２が前記綴じ桿を開放する方向に回動することを禁止するストッパを前記操作部材３に設けており、前記操作部材３が前記ロック位置にあるときに前記ストッパが前記綴じ桿部材１、２の所定部位１４、２４に当接する一方、操作部材３がアンロック位置にあるときには綴じ桿部材１、２を回動させてもストッパが綴じ桿部材の所定部位１４、２４には接触しない。綴じ桿部材１、３及び操作部材３によって綴じ具０の基本構成が完結するため、部品点数の削減につながる。
The operating member 3 is provided with a stopper that prohibits the binding rod members 1 and 2 from rotating in a direction to open the binding rod, and the stopper is moved when the operating member 3 is in the locked position. While contacting the predetermined portions 14 and 24 of the binding rod members 1 and 2, while the operating member 3 is in the unlocked position, the stopper remains on the predetermined portions 14 and 24 of the binding rod member even if the binding rod members 1 and 2 are rotated. Do not touch. Since the basic configuration of the binding tool 0 is completed by the binding rod members 1 and 3 and the operation member 3, the number of parts is reduced.
並びに、本実施形態によれば、ヒンジを介してその軸心周りに相対回動可能であり、回動動作を通じて綴じ桿を開閉させる一組の綴じ桿部材１、２と、前記ヒンジの軸１３、２３を覆うとともに前記綴じ桿部材１、２に対し前記軸心方向に沿ってスライド可能であり、綴じ桿部材１、２が前記綴じ桿を開放する方向に回動することを禁止するストッパを有し、当該ストッパが綴じ桿部材１、２の所定部位に接触するロック位置と、綴じ桿部材１、２を回動させても当該ストッパが綴じ桿部材１、２の所定部位１４、２４に接触しないアンロック位置とを選択的にとり得る操作部材３とを具備する綴じ具０を構成したため、ヒンジの軸１３、２３が凸凹した感触をユーザに与える可能性が小さくなる。のみならず、操作部材３を軸心方向にスライド操作することで、綴じ桿の開放状態と閉止状態との切り替えを行い得る。
In addition, according to the present embodiment, the pair of binding rod members 1 and 2 that can be relatively rotated around the axis via the hinge and open and close the binding rod through the pivoting operation, and the shaft 13 of the hinge. 23, and a stopper that is slidable along the axial direction with respect to the binding rod members 1 and 2 and prohibits the binding rod members 1 and 2 from rotating in a direction to open the binding rod. A locking position where the stopper comes into contact with a predetermined portion of the binding rod members 1 and 2, and even if the binding rod members 1 and 2 are rotated, the stopper is fixed to the predetermined portions 14 and 24 of the binding rod members 1 and 2. Since the binding tool 0 including the operation member 3 that can selectively take the unlocking position that does not contact is configured, the possibility that the hinge shafts 13 and 23 are uneven is less likely to be given to the user. Not only can the operating member 3 be slid in the axial direction to switch the binding rod between the open state and the closed state.
前記ヒンジの軸１３、２３が略円筒状の外周をなし、前記操作部材３がこのヒンジの軸１３、２３をくわえ込むようにヒンジの軸１３、２３に係合するものであるため、操作部材３の形状が徒に複雑化しない。また、操作部材３の外周面を平滑化して手触りの良化を図ることができる。
Since the shafts 13 and 23 of the hinge have a substantially cylindrical outer periphery, and the operation member 3 is engaged with the shafts 13 and 23 of the hinge so as to hold the hinge shafts 13 and 23, the operation member The shape of 3 is not complicated. In addition, the outer peripheral surface of the operation member 3 can be smoothed to improve the touch.
前記一組の綴じ桿部材１、２の各々に略円筒状の外周をなし前記ヒンジの軸となる軸体１３、２３を設け、両者の軸体１３、２３を直列に配置した状態で前記操作部材３がこれらを相対回動可能に保持するため、各軸体１３、２３の全てを貫通するような長い細棒が不要となる。
Each of the pair of binding rod members 1 and 2 is provided with shaft bodies 13 and 23 that form a substantially cylindrical outer periphery and serve as a shaft of the hinge, and the shaft bodies 13 and 23 are arranged in series with the operation. Since the member 3 holds these so as to be capable of relative rotation, a long thin bar penetrating all the shaft bodies 13 and 23 is not necessary.
前記両軸体１３、２３の互いに対向する端面の一方に凸部１３２、２３２を形成し、他方にこの凸部１３２、２３２を受け入れる凹部１３１、２３１を形成して、これら凸部１３２、２３２と凹部１３１、２３１との係合構造を構成しているため、綴じ具０の組立作業の容易化に資する上、綴じ具０としての一体性が高まり、何れかの綴じ桿部材１、２が脱落するようなおそれも小さくなる。
Convex portions 132 and 232 are formed on one of the end faces of the shaft bodies 13 and 23 facing each other, and concave portions 131 and 231 for receiving the convex portions 132 and 232 are formed on the other. Since the engagement structure with the recesses 131 and 231 is configured, it contributes to the ease of assembling work of the binding tool 0, and the integrity as the binding tool 0 is enhanced, and any binding rod member 1 or 2 is dropped. The risk of doing so is also reduced.
前記操作部材３は、並立する側壁３１、３２と両側壁３１、３２を連結する底壁３３とを備え、側壁３１、３２及び底壁３３によって包囲される内部空間に前記ヒンジの軸１３、２３を収容するものであり、前記側壁３１、３２の端縁に切欠３１１、３２１を形成し、切欠３１１、３２１に隣接する（切り欠いていない）部位を前記ストッパとしており、前記操作部材３が前記アンロック位置にあるときには前記綴じ桿部材１、２の所定部位１４、２４がこの切欠３１１、３２１内に収まるものであるため、綴じ桿部材１、２及び操作部材３によって綴じ具０の基本構成が完結し、部品点数の削減につながる。
The operation member 3 includes side walls 31 and 32 arranged side by side and a bottom wall 33 connecting both side walls 31 and 32, and the hinge shafts 13 and 23 are disposed in an internal space surrounded by the side walls 31 and 32 and the bottom wall 33. Cutouts 311 and 321 are formed at the edges of the side walls 31 and 32, and a portion adjacent to the cutouts 311 and 321 (not cutout) is used as the stopper. Since the predetermined portions 14 and 24 of the binding rod members 1 and 2 are accommodated in the notches 311 and 321 when in the unlocked position, the basic configuration of the binding tool 0 is formed by the binding rod members 1 and 2 and the operation member 3. Is completed, leading to a reduction in the number of parts.
前記操作部材３を前記アンロック位置から前記ロック位置に向けて変位させる方向に弾性付勢する弾性付勢部材４を具備しており、綴じ桿を閉じる回動方向に弾性付勢するばね等が不要である。当該弾性付勢部材４の綴じ桿部材の配置の自由度も高い。
An elastic urging member 4 that elastically urges the operation member 3 in a direction that displaces the operation member 3 from the unlock position toward the lock position, and a spring that urges elastically in a rotational direction that closes the binding rod. It is unnecessary. The degree of freedom of arrangement of the binding rod member of the elastic biasing member 4 is also high.
＜第二実施形態＞続いて、図２０ないし図４１に示す、本発明の他の実施形態を説明する。但し、前述した第一実施形態と同一または同等の構成部分には同一の符号を付すとともに、その説明を省略または簡略化する。当該構成部分については、第一実施形態の詳説を参照されたい。図２０ないし図３７は、ちょうど第一実施形態の図２ないし図１９に各々対応している。
<Second Embodiment> Next, another embodiment of the present invention shown in FIGS. 20 to 41 will be described. However, the same or equivalent components as those in the first embodiment described above are denoted by the same reference numerals, and the description thereof is omitted or simplified. Refer to the detailed description of the first embodiment for the components. 20 to 37 correspond to FIGS. 2 to 19 of the first embodiment, respectively.
本実施形態の綴じ具０もまた、開閉可能な複数本の綴じ桿を備えたリング綴じ具である。綴じ桿は、予め紙葉類Ｓに穿たれている綴じ孔に挿通されて、紙葉類Ｓを綴じ止める。そして、ノートの中紙となる複数枚のリーフやクリアブックのリフィル等Ｓを綴じることで、リングノートとしての用途に供することができる。リングノートは、ページを１８０°の角度に開いた見開き状態とすることが可能である。
The binding tool 0 of the present embodiment is also a ring binding tool provided with a plurality of binding rods that can be opened and closed. The binding fold is inserted into a binding hole that has been made in the paper sheet S in advance, and binds the paper sheet S. Then, by binding a plurality of leaves or clear book refills S which are the middle sheets of the notebook, it can be used as a ring notebook. The ring notebook can be in a spread state where the page is opened at an angle of 180 °.
以降、本実施形態と第一実施形態との相異点を列挙する。まず、図３０ないし図３３等に示すように、軸心方向から見て、本実施形態における綴じ桿要素１２、２２の先端部は湾曲してはおらず、相手方の綴じ桿要素２１、１１に向かうように直線的に伸びている。その伸長方向は、基体１１、２１の頂面１１３、２１３に対して略平行である。綴じ桿要素１２、２２の先端部が合决りになっている点は、第一実施形態と同様である。
Hereinafter, differences between this embodiment and the first embodiment are listed. First, as shown in FIGS. 30 to 33 and the like, when viewed from the axial direction, the leading ends of the binding rod elements 12 and 22 in this embodiment are not curved, and are directed to the binding rod elements 21 and 11 of the other party. So as to extend linearly. The extending direction is substantially parallel to the top surfaces 113 and 213 of the base bodies 11 and 21. The point that the front ends of the binding rod elements 12 and 22 are stitched together is the same as in the first embodiment.
綴じ桿要素１２、２２の先端部が直線的に伸びていることにより、綴じ孔に綴じ桿要素１２、２２を挿通して綴じている紙葉類Ｓのページ繰り操作が円滑になる。のみならず、綴じ桿部材１、２の成形が容易になるという効用をも得られる。各綴じ桿部材１、２はそれぞれ樹脂成形品であるが、第一実施形態における綴じ桿部材１、２では、綴じ桿要素１２、２２の先端部とそれ以外の部分とを一括に成形することができず、二色成形しなくてはならない弱みがあった。本実施形態では、綴じ桿部材１、２を作製するにあたり、成形金型における綴じ桿要素１２、２２の基端側（または、基体１１、２１の側）にあたる箇所から金型に樹脂を注入し、その樹脂を綴じ桿要素１２、２２の先端側にあたる箇所まで行き渡らせることが容易である上、成形後に金型を綴じ桿要素１２、２２の先端部の伸長方向に沿って抜くことが可能となる。
Since the leading end portions of the binding rod elements 12 and 22 extend linearly, the page turning operation of the paper sheet S that is bound and inserted through the binding rod elements 12 and 22 into the binding hole becomes smooth. In addition, the utility of facilitating the forming of the binding rod members 1 and 2 can be obtained. Each binding rod member 1 and 2 is a resin molded product. However, in the binding rod members 1 and 2 in the first embodiment, the leading end portions of the binding rod elements 12 and 22 and the other portions are molded together. However, there was a weakness that had to be two-color molded. In the present embodiment, when the binding rod members 1 and 2 are manufactured, a resin is injected into the mold from a position corresponding to the proximal end side of the binding rod elements 12 and 22 (or the bases 11 and 21 side) in the molding die. In addition, it is easy to spread the resin to a position corresponding to the tip side of the binding rod elements 12 and 22, and after the molding, the mold can be pulled out along the extending direction of the tip portion of the binding rod elements 12 and 22. Become.
次に、本実施形態における操作部材３は、第一実施形態における操作部材３とは幾つかの細部が異なっている。図３０ないし図３３等に示すように、本実施形態における操作部材３の底壁３３は、第一実施形態におけるそれと比較して、より平坦に近い形状となっている。また、この底壁３３に穿っている貫通孔３３１の数が、第一実施形態よりも少ない。
Next, the operation member 3 in this embodiment is different from the operation member 3 in the first embodiment in some details. As shown in FIG. 30 thru | or 33 etc., the bottom wall 33 of the operation member 3 in this embodiment has a shape nearer flatness than that in the first embodiment. Further, the number of through holes 331 formed in the bottom wall 33 is smaller than that in the first embodiment.
そもそも、底壁３３の孔３３１は、側壁３１、３２から内側方に突出する突起３１２、３２２を成形する型を抜くために形成されるものである。第一実施形態では、一方側の側壁３１１から突出する突起３１２と他方側の側壁３２１から突出する突起３２２とが常に対をなして両立しており、孔３３１の数も自然と多くなっていた。これに対し、図３４及び図３７に示すように、本実施形態では、操作部材３の端部及び中間部を除き、突起３１２と突起３２２とは対をなしておらず、両者は軸心方向に沿って互いに偏倚している。換言すれば、突起３１２と突起３２２とを、軸心方向に沿って互い違いに設けている。故に、本実施形態では、孔３３１の数が少なくなっており、操作部材３の強度が向上しているだけでなく、ユーザが底壁３３に指を触れたときの手触りも向上している。
In the first place, the hole 331 in the bottom wall 33 is formed to remove a mold for forming the projections 312 and 322 protruding inward from the side walls 31 and 32. In the first embodiment, the protrusion 312 protruding from the side wall 311 on one side and the protrusion 322 protruding from the side wall 321 on the other side are always paired and the number of holes 331 is naturally increased. . On the other hand, as shown in FIGS. 34 and 37, in the present embodiment, the protrusion 312 and the protrusion 322 are not paired except for the end portion and the intermediate portion of the operation member 3, and both are in the axial direction. Are biased toward each other. In other words, the protrusions 312 and the protrusions 322 are provided alternately along the axial direction. Therefore, in this embodiment, the number of the holes 331 is reduced, and not only the strength of the operation member 3 is improved, but also the touch when the user touches the bottom wall 33 is improved.
本実施形態における操作部材３の把手３４は、第一実施形態における把手３４よりも短く切り詰めてある。図２４、図２５、図２８、図２９等に示すように、平面視把手３４の端縁は、拡開部３５の傾斜面３５１、３５２とともに、概ね涙滴型の縁辺をなすような外観を呈している。加えて、把手３４に最も近い位置にある側壁３１の切欠３１１の軸心方向に沿った寸法を、他の切欠３１１、３２１と比較して小さくしている。綴じ桿を開放するときにこの切欠３１１内に収まる綴じ桿部材１の腕部１４についても、軸心方向に沿った寸法を同寸以下となるように設定してある。
The handle 34 of the operation member 3 in this embodiment is cut shorter than the handle 34 in the first embodiment. 24, FIG. 25, FIG. 28, FIG. 29, and the like, the end edge of the planar handle 34 has an appearance that forms an almost teardrop-shaped edge together with the inclined surfaces 351 and 352 of the expanding portion 35. Presents. In addition, the dimension along the axial direction of the notch 311 of the side wall 31 closest to the handle 34 is made smaller than those of the other notches 311 and 321. The arm portion 14 of the binding rod member 1 that fits in the notch 311 when the binding rod is opened is also set so that the dimension along the axial direction is equal to or less than the same dimension.
第一実施形態では、操作部材３の周壁３１、３２、３３によって包囲された内部空間が、軸心方向に沿った両端部にて閉塞されていた。これに対し、図３８に示すように、本実施形態では、操作部材３の他端側の端部に壁を設けておらず、操作部材３の他端側にて内部空間が開放している。このことは、操作部材３の成形にとって有利となる。即ち、操作部材３を成形する型を抜く方向について制約が少なくなり（操作部材３の他端部位において、操作部材３の延伸方向つまりは軸心方向に沿って型を抜くことが許容される）、設計の自由度が増すとともに製造コストの低減に奏効し得る。
In the first embodiment, the internal space surrounded by the peripheral walls 31, 32, 33 of the operation member 3 is closed at both ends along the axial direction. On the other hand, as shown in FIG. 38, in the present embodiment, no wall is provided at the other end side of the operation member 3, and the internal space is open on the other end side of the operation member 3. . This is advantageous for forming the operation member 3. That is, there are less restrictions on the direction in which the mold for molding the operating member 3 is pulled out (at the other end portion of the operating member 3, it is allowed to pull out the mold along the extending direction of the operating member 3, that is, the axial direction). Thus, the degree of freedom in design increases and the manufacturing cost can be reduced.
さらに、図３８ないし図４１に示しているように、操作部材３の軸心方向に沿った他端側において、側壁３１、３２から内側方に突出する係合部３１３、３２３を形成している。他方、綴じ桿部材２の、軸心方向に沿った最も他端側に位置する軸体２３の外周面にも、外側方に突出する被係合部２３３を形成してある。
Further, as shown in FIGS. 38 to 41, engaging portions 313 and 323 that protrude inward from the side walls 31 and 32 are formed on the other end side along the axial direction of the operation member 3. . On the other hand, an engaged portion 233 protruding outward is also formed on the outer peripheral surface of the shaft body 23 located on the most other end side along the axial direction of the binding rod member 2.
図４０の平断面図は、操作部材３がロック位置にある状態を示している。操作部材３がロック位置にあるとき、側壁３１、３２から突出する係合部３１３、３２３と、軸体２３から突出する被係合部２３３とは軸心方向に沿って離間している。
40 shows a state where the operation member 3 is in the locked position. When the operating member 3 is in the locked position, the engaging portions 313 and 323 protruding from the side walls 31 and 32 and the engaged portion 233 protruding from the shaft body 23 are separated from each other in the axial direction.
対して、図４１の平断面図は、操作部材３がアンロック位置にある状態を示している。操作部材３をロック位置からアンロック位置にスライド移動させると、綴じ桿部材１、２がその軸体１３、２３を中心として綴じ桿を開放する方向に回動するとともに、側壁から突出する係合部３１３、３２３が軸体２３から突出する被係合部２３３に向かって接近し、遂にはこの被係合部２３３を越えてこれに係合する。
On the other hand, the plan sectional view of FIG. 41 shows a state in which the operation member 3 is in the unlock position. When the operating member 3 is slid from the locked position to the unlocked position, the binding rod members 1 and 2 rotate about the shafts 13 and 23 in the direction to open the binding rod and project from the side wall. The parts 313 and 323 approach toward the engaged part 233 protruding from the shaft body 23 and finally engage with the engaged part 233 beyond this.
既に述べた通り、操作部材３がアンロック位置にある状態では、フック２６、３６に両端を支持させたコイルばね４が引き伸ばされ、操作部材３をロック位置に引き戻すような引っ張り弾性力を発揮する。係合部３１３、３２３は、被係合部２３３に係合する際にユーザの手指にクリック感を与えつつ、被係合部２３３に係合することで操作部材３がユーザの意図によらずロック位置に帰還しようとすることを抑制する働きをする。
As already described, in a state where the operation member 3 is in the unlock position, the coil spring 4 having both ends supported by the hooks 26 and 36 is stretched to exert a tensile elastic force that pulls the operation member 3 back to the lock position. . The engaging portions 313 and 323 are engaged with the engaged portion 233 while giving a click feeling to the user's finger when engaging the engaged portion 233, so that the operation member 3 is not intended by the user. It works to suppress attempts to return to the locked position.
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。列挙すると、上記実施形態では、第一の綴じ桿部材と第二の綴じ桿部材とは別体の部材であったが、両者を樹脂ヒンジを介して一体成形してもよい。
Note that the present invention is not limited to the embodiment described in detail above. If it enumerates, in the said embodiment, although the 1st binding rod member and the 2nd binding rod member were separate members, you may integrally form both through a resin hinge.
弾性付勢部材は、コイルばねには限定されない。その他の態様のもの、例えば板ばねや樹脂ばね、ゴムばね等を採用しても構わない。
The elastic biasing member is not limited to a coil spring. Other embodiments such as a leaf spring, a resin spring, and a rubber spring may be employed.
操作部材の一端側と綴じ桿部材（の基体）の一端側との間に、圧縮弾性力を発生させる弾性付勢部材、即ち圧縮コイルばねの類を介在させることも考えられる。
It is also conceivable that an elastic biasing member that generates a compressive elastic force, that is, a compression coil spring, is interposed between one end side of the operation member and one end side of the binding rod member (its base).
また、特に、操作力変換機構（操作部材の一端側の拡開部）は、必須の構成要素ではない。（操作部材をアンロック位置においた後）両綴じ桿部材を相対回動させて綴じ桿を開くために、綴じている紙葉類を介して綴じ桿要素を引っ張るようにしてもよいし、綴じている紙葉類の自重を利用してもよい。あるいは、両綴じ桿要素を互いに離反させる回動方向に弾性付勢する付勢部材（ねじりばね等）を実装してもよい。
In particular, the operating force conversion mechanism (the expanding portion on one end side of the operating member) is not an essential component. (After placing the operation member in the unlocked position) In order to open the binding rod by rotating both the binding rod members relative to each other, the binding rod element may be pulled through the bound paper sheets, or the binding may be performed. You may use the weight of the paper. Alternatively, a biasing member (such as a torsion spring) that elastically biases both binding rod elements in a rotational direction that separates them from each other may be mounted.
その他各部の具体的構成は、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。
Other specific configurations of each part can be variously modified without departing from the gist of the present invention.
本発明は、紙葉類を綴じ止める綴じ具に適用することができる。
The present invention can be applied to a binding tool for binding paper sheets.
