米国特許明細書第４８７８２６９号公報U.S. Pat. No. 4,878,269
　この発明が解決しようとする主たる問題点は、この種のコードロックの機能をより向上させる点にある。より具体的には、この発明は、第一に、コードロックに通された紐状体に一方向に向けた張力が作用されたときはこの紐状体に対する留め付け力を合理的に強めるようにし、第二に、コードロックに通された紐状体に他方向に向けた張力が作用されたときはこの紐状体に対する留め付け力を合理的に弱めるようにすることを目的としている。 The main problem to be solved by the present invention is to further improve the function of this type of code lock. More specifically, according to the present invention, firstly, when a tension in one direction is applied to the string-like body passed through the cord lock, the fastening force to the string-like body is reasonably increased. Secondly, when a tension in the other direction is applied to the string-like body passed through the cord lock, the object is to reasonably weaken the fastening force to the string-like body.
　前記第一の目的を達成するために、この発明にあっては、コードロックを、第一開口部と、これに対向する第二開口部とを有し、両開口部を通じて内部に紐状体を通過させる外側パーツと、
　前記紐状体の通過方向に沿った移動可能に前記外側パーツに組み合わされる内側パーツとを有し、
　前記外側パーツは、第一開口部と第二開口部との間に前記紐状体に対する留め付け用内壁を有すると共に、この留め付け用内壁の内方に前記紐状体の通過方向に延びる案内溝を有しており、
　前記内側パーツは、基部と、前記第二開口部側でこの基部に連接されて前記第一開口部側に延び、この第一開口部側に位置される自由端と前記留め付け用内壁との間に前記紐状体を通過させる可動腕部とを有しており、
　この可動腕部には、前記案内溝に案内される被案内部と、前記自由端から前記留め付け用内壁に向けて突き出して前記紐状体に突き立てられる爪部とが備えられており、
　前記案内溝と被案内部とによって、前記紐状体に対する前記第二開口部から引き出される向きへの張力の作用により所定位置よりこの第二開口部側に内側パーツが近づくに連れて、前記自由端と前記留め付け用内壁との間の距離を漸減させる前記可動腕部の可動がなされるようになっているものとした。 In order to achieve the first object, according to the present invention, the cord lock has a first opening and a second opening opposite to the cord lock, and a string-like body is internally provided through both openings. The outer parts that pass through,
An inner part which is combined with the outer part so as to be movable along the passing direction of the string-like body,
The outer part has an inner wall for fastening the string-like body between the first opening and the second opening, and extends in the passing direction of the string-like body inward of the inner wall for fastening. Has a groove,
The inner part is connected to the base on the second opening side and extends to the first opening side, and includes a free end positioned on the first opening side and the fastening inner wall. A movable arm portion for passing the string-like body therebetween,
The movable arm portion includes a guided portion guided by the guide groove, and a claw portion protruding from the free end toward the fastening inner wall and protruding from the string-like body,
As the inner part approaches the second opening side from a predetermined position by the action of the tension in the direction pulled out from the second opening part to the string-like body by the guide groove and the guided part, the free part The movable arm portion that gradually decreases the distance between the end and the inner wall for fastening is configured to be movable.
　かかる構成によれば、前記紐状体に対して前記第二開口部から引き出される向きへの張力が作用されたときには、かかる紐状体に対する留め付け用内壁と可動腕部の自由端との間での挟持状態を内側パーツの第二開口部側への移動を通じて強化することができ、この向きへの紐状体の抜け出しを効果的に阻止することができる。 According to this configuration, when a tension is applied to the string-like body in the direction of being pulled out from the second opening, the space between the inner wall for fastening the string-like body and the free end of the movable arm portion Can be strengthened through movement of the inner part toward the second opening, and the string-like body can be effectively prevented from coming out in this direction.
　かかるコードロックにおいて、さらに、前記案内溝と被案内部とによって、紐状体に対する第一開口部から引き出される向きへの張力の作用により所定位置より第一開口部側に内側パーツが近づくに連れて、自由端と留め付け用内壁との間の距離を漸増させる前記可動腕部の可動がなされるようにしておけば、前記第二の目的を達成することができる。すなわち、前記紐状体に対して前記第一開口部から引き出される向きへの張力が作用されたときには、かかる紐状体に対する留め付け用内壁と可動腕部の自由端との間での挟持状態を内側パーツの第一開口部側への移動を通じて弱化することができ、この向きへは紐状体を所望の長さ分引き出すことができる。 In such a cord lock, the guide groove and the guided portion further cause the inner part to approach the first opening side from the predetermined position by the action of the tension in the direction in which the string-like body is pulled out from the first opening. Thus, the second object can be achieved by moving the movable arm portion that gradually increases the distance between the free end and the fastening inner wall. That is, when tension is applied to the string-like body in the direction pulled out from the first opening, the clamped state between the inner wall for fastening the string-like body and the free end of the movable arm portion Can be weakened through movement of the inner part toward the first opening, and the string-like body can be pulled out in this direction by a desired length.
　この発明によれば、コードロックに通された紐状体に一方向に向けた張力が作用されたときはこの紐状体に対するコードロックの留め付け力を合理的に強めさせることができる。 According to the present invention, when a tension directed in one direction is applied to the string-like body passed through the cord lock, the fastening force of the cord lock to the string-like body can be increased reasonably.

　以下、図１～図１９に基づいて、この発明の典型的な実施の形態について、説明する。この実施の形態にかかるコードロックは、紐状体Ｃｄの任意の位置に留め付け可能であり、また、この留め付け状態から紐状体Ｃｄを一方向に引っ張った場合に限りこの留め付け位置の調整ができ、また、コードロックを構成する後述の内側パーツＭを操作することでこの留め付け状態の完全解除も可能になっている。 Hereinafter, typical embodiments of the present invention will be described with reference to FIGS. The cord lock according to this embodiment can be fastened to an arbitrary position of the string-like body Cd, and only when the string-like body Cd is pulled in one direction from this fastened state. It can be adjusted, and the fastening state can be completely released by operating an inner part M (described later) constituting the cord lock.
　かかる紐状体Ｃｄは、このようなコードロックの留め付けが可能なものであれば、その形状（丸紐、平紐など）、材質や構造（編み紐、ゴム紐、合成樹脂製の紐など）は問われない。かかるコードロックは、典型的には、こうした紐状体Ｃｄにより絞られたり、引き締められたりする箇所を備えた各種の物品におけるこの紐状体Ｃｄに留め付けられて、その留め付け位置を変えることでこのような箇所を絞ったり、緩めたりするように用いられる。 If such a cord-like body Cd can be fastened with such a cord lock, its shape (round cord, flat cord, etc.), material and structure (knitted cord, rubber cord, synthetic resin cord, etc.) Is not questioned. Such a cord lock is typically fastened to the string-like body Cd in various articles having portions to be squeezed or tightened by the string-like body Cd, and the fastening position thereof is changed. It is used to squeeze or loosen such a part.
　かかるコードロックは、外側パーツＦと、この外側パーツＦに組み合わされる内側パーツＭとから構成されている。 The cord lock is composed of an outer part F and an inner part M combined with the outer part F.
　外側パーツＦは、第一開口部１と、これに対向する位置に第二開口部２とを有し、両開口部１、２を通じて内部に紐状体Ｃｄを通過させるようになっている。 The outer part F has a first opening 1 and a second opening 2 at a position opposite to the first opening 1, and allows the string-like body Cd to pass through both the openings 1 and 2.
　図示の例では、外側パーツＦは、扁平の筒状を呈している。すなわち、外側パーツＦは、幅広の表板部３及び裏板部４と、左右の側板部５、５とを有している。 In the illustrated example, the outer part F has a flat cylindrical shape. That is, the outer part F has a wide front plate portion 3 and a back plate portion 4, and left and right side plate portions 5 and 5.

It is formed between y2. In the outer part F, a location on the first line segment y1 is the first opening 1 and a location on the second line segment y2 is the second opening 2. Both the left and right side plate portions 5 and 5 are inclined so as to gradually approach the center line x as they go from the first opening 1 to the second opening 2. Thereby, in the example of illustration, the 2nd opening part 2 makes the dimension of the left-right direction smaller than the 1st opening part 1. FIG.
　前記表板部３と裏板部４はいずれも、前記第一線分ｙ１よりも外側に張り出す第一張り出し部６と、前記第二線分ｙ２よりも外側に張り出す第二張り出し部７とを備えている。表板部３の第二張り出し部７の頂端と裏板部４の第二張り出し部７の頂端との間には、仕切部８が架設されており、第二開口部２側はこの仕切部８により左右に二分された様子となっている。 The front plate portion 3 and the back plate portion 4 both have a first overhang portion 6 projecting outward from the first line segment y1 and a second overhang portion 7 projecting outward from the second line segment y2. And. A partition portion 8 is installed between the top end of the second overhang portion 7 of the front plate portion 3 and the top end of the second overhang portion 7 of the back plate portion 4, and the second opening portion 2 side is this partition portion. 8 is divided into left and right.

Further, in the back plate portion 4, the guide groove 9 is configured as a watermark groove penetrating the inner surface portion inside and outside on the left and right sides of the center line x. However, the guide groove 9 may be formed by a watermark groove in both the front plate portion 3 and the back plate portion 4, and bottomed in both the front plate portion 3 and the back plate portion 4. It may be formed by a groove.
　かかる案内溝９は、前記紐状体Ｃｄの通過方向に長く、また、後述の内側パーツＭの被案内部１１ｈを遊びを持って納める幅を備えている。また、かかる案内溝９は、前記第一線分ｙ１及び第二線分ｙ２との間を二分する前記中心線ｘに直交する仮想の第三線分ｙ３上に溝内端９ａを位置させて、前記第一線分ｙ１を超えて第一張り出し部６に至り、この第一張り出し部６に溝外端を位置させるように形成されている。（図１４、図１５） The guide groove 9 is long in the passing direction of the string-like body Cd, and has a width for accommodating a guided portion 11h of the inner part M described later with play. The guide groove 9 has a groove inner end 9a positioned on a virtual third line segment y3 perpendicular to the center line x that bisects the first line segment y1 and the second line segment y2. It is formed so as to reach the first overhanging portion 6 beyond the first line segment y1 and to position the outer end of the groove in the first overhanging portion 6. (FIGS. 14 and 15)
　かかる案内溝９における前記中心線ｘ側に位置される溝壁９ｃは、前記第三線分ｙ３と前記第一線分ｙ１の外側にあって前記中心線ｘに直交する仮想の第四線分ｙ４との間において、この第四線分ｙ４に近づくに連れて次第に前記中心線ｘとの距離を小さくさせるように傾斜している。（図１４、図１５） A groove wall 9c located on the center line x side in the guide groove 9 is outside the third line segment y3 and the first line segment y1 and is a virtual fourth line segment y4 orthogonal to the center line x. Between the center line x and the fourth line segment y4 as the distance from the center line x gradually decreases. (FIGS. 14 and 15)
　また、かかる案内溝９における前記留め付け用内壁５ａ側に位置される溝壁９ｄは、前記第三線分ｙ３と前記第一線分ｙ１のやや外側となる箇所との間において、この第一線分ｙ１側に近づくに連れて次第に前記中心線ｘとの距離を小さくさせるように傾斜している。（図１４、図１５） In addition, the groove wall 9d positioned on the side of the fastening inner wall 5a in the guide groove 9 has a first line between the third line segment y3 and a portion slightly outside the first line segment y1. As it approaches the minute y1 side, the distance from the center line x gradually decreases. (FIGS. 14 and 15)
　図示の例では、前記裏板部４においては、案内溝９は、前記第一張り出し部６の縁部と第四線分ｙ４との間に溝外端９ｂを位置させている。また、かかる裏板部４の内面には、前記中心線ｘの左右においてそれぞれ、案内溝９の留め付け用内壁５ａ側に位置される溝縁と第一張り出し部６の縁部との間に亘る導入溝４ａが形成されている。 In the illustrated example, in the back plate portion 4, the guide groove 9 has a groove outer end 9b positioned between the edge portion of the first overhang portion 6 and the fourth line segment y4. In addition, on the inner surface of the back plate portion 4, between the groove edge located on the side of the inner wall 5 a for fastening of the guide groove 9 and the edge portion of the first overhang portion 6 on the left and right sides of the center line x, respectively. A leading introduction groove 4a is formed.
　一方、図示の例では、前記表板部３においては、案内溝９は、前記第四線分ｙ４位置から第一張り出し部６の縁部まで続き、この縁部において溝外端９ｂを開放させている。 On the other hand, in the illustrated example, in the front plate portion 3, the guide groove 9 continues from the position of the fourth line segment y4 to the edge portion of the first overhang portion 6, and the groove outer end 9b is opened at this edge portion. ing.
　一方、内側パーツＭは、前記紐状体Ｃｄの通過方向に沿った移動可能に前記外側パーツＦに組み合わされるようになっている。 On the other hand, the inner part M is combined with the outer part F so as to be movable along the passing direction of the string-like body Cd.
　かかる内側パーツＭは、基部１０と、前記第二開口部２側でこの基部１０に連接されて前記第一開口部１側に延び、この第一開口部１側に位置される自由端１１ａと前記留め付け用内壁５ａとの間に前記紐状体Ｃｄを通過させる可動腕部１１とを有している。それと共に、かかる可動腕部１１には、前記案内溝９に案内される被案内部１１ｈと、前記自由端１１ａから前記留め付け用内壁５ａに向けて突き出して前記紐状体Ｃｄに突き立てられる爪部１１ｃとが備えられている。 The inner part M includes a base 10 and a free end 11a that is connected to the base 10 on the second opening 2 side and extends to the first opening 1 side, and is positioned on the first opening 1 side. A movable arm portion 11 through which the string-like body Cd passes is provided between the fastening inner wall 5a. At the same time, the movable arm 11 protrudes from the free end 11a toward the fastening inner wall 5a and is guided by the string-like body Cd. A claw portion 11c is provided.
　図示の例では、内側パーツＭは、軸状をなす基部１０と、この基部１０の一端１０ａから左側に突き出す可動腕部１１と、この基部１０の一端１０ａから右側に突き出す可動腕部１１とを備えている。左右の可動腕部１１、１１はそれぞれ、その自由端１１ａを基部１０の他端１０ｂ側に向けると共に、この自由端１１ａに近づくに連れて基部１０との間の間隔を広げるように、前記基部１０の一端１０ａから斜めに突き出している。また、図示の例では、左右の可動腕部１１、１１はそれぞれ、その基端１１ｂを基部１０の一端１０ａに一体化させており、左右の可動腕部１１、１１はそれぞれ、この基端１１ｂを弾性変形の中心として前記自由端１１ａと基部１０との距離を広げ又狭めるように弾性変形により可動されるようになっている。左側の可動腕部１１に対し、右側の可動腕部１１は、前記基部１０を中心として線対称となる形状を持つように構成されている。 In the illustrated example, the inner part M includes a base 10 having an axial shape, a movable arm 11 protruding leftward from one end 10a of the base 10, and a movable arm 11 protruding rightward from one end 10a of the base 10. I have. Each of the left and right movable arm portions 11 and 11 has its base end so that its free end 11a is directed toward the other end 10b side of the base portion 10 and the distance from the base portion 10 is increased as it approaches this free end 11a. 10 protrudes diagonally from one end 10a. Further, in the illustrated example, the left and right movable arm portions 11 and 11 have their base ends 11b integrated with one end 10a of the base portion 10, respectively, and the left and right movable arm portions 11 and 11 respectively have the base end 11b. Is moved by elastic deformation so that the distance between the free end 11a and the base 10 is increased or decreased. With respect to the left movable arm portion 11, the right movable arm portion 11 is configured to have a line-symmetric shape with respect to the base portion 10.
　かかる内側パーツＭは、外側パーツＦの第一開口部１より、この外側パーツＦ内に、前記基部１０の一端１０ａを先にし、かつ、かかる左側の可動腕部１１が左側の留め付け用内壁５ａに向き合い、右側の可動腕部１１が右側の留め付け用内壁５ａに向き合う向きで、納められるようになっている。 The inner part M has the one end 10a of the base part 10 in the outer part F before the first opening 1 of the outer part F, and the left movable arm part 11 has a left inner wall for fastening. 5a, and the right movable arm portion 11 is accommodated in a direction facing the right fastening inner wall 5a.
　左右の可動腕部１１、１１はそれぞれ、その自由端１１ａにおける留め付け用内壁５ａに向き合う箇所に、前記爪部１１ｃを備えている。図示の例では、かかる爪部１１ｃは、可動腕部１１の長さ方向において隣り合う爪部１１ｃとの間に間隔を開けて、三つ設けられている。各爪部１１ｃは、外側パーツＦの表板部３の内面に向き合う幅側側面１１ｄと、裏板部４の内面に向き合う幅側側面１１ｄと、両幅側側面１１ｄ、１１ｄにそれぞれ直交する厚さ側側面１１ｅとを有している。かかる爪部１１ｃにおける前記第一開口部１側に向けられる厚さ側側面１１ｅと、前記第二開口部２側に向けられる厚さ側側面１１ｅとは、鋭角に交わって爪部１１ｃの爪先を形成させている。かかる爪部１１ｃにおける前記第一開口部１側に向けられる厚さ側側面１１ｅは前記自由端１１ａと留め付け用内壁５ａとの間を通過する紐状体Ｃｄの長さ方向に略直交する直交面１１ｆとなっており、一方、前記第二開口部２側に向けられる厚さ側側面１１ｅは前記第一開口部１側に向けられる厚さ側側面１１ｅとの間に前記鋭角を形成する傾斜面１１ｇとなっている。 Each of the left and right movable arm portions 11 and 11 includes the claw portion 11c at a position facing the fastening inner wall 5a at the free end 11a. In the illustrated example, three such claw portions 11 c are provided with a gap between the claw portions 11 c adjacent to each other in the length direction of the movable arm portion 11. Each claw portion 11c has a width side surface 11d facing the inner surface of the front plate portion 3 of the outer part F, a width side surface 11d facing the inner surface of the back plate portion 4, and a thickness orthogonal to both width side surfaces 11d and 11d. And a side surface 11e. In the claw portion 11c, the thickness side surface 11e directed to the first opening 1 side and the thickness side surface 11e directed to the second opening 2 side cross each other at an acute angle so that the toe of the claw portion 11c It is formed. A thickness side surface 11e directed to the first opening 1 side in the claw portion 11c is orthogonal to the length direction of the string-like body Cd passing between the free end 11a and the fastening inner wall 5a. On the other hand, the thickness side surface 11e directed to the second opening 2 side is inclined to form the acute angle with the thickness side surface 11e directed to the first opening 1 side. The surface is 11g.
　また、図示の例では、可動腕部１１の自由端１１ａにおける、前記表板部３に向き合う箇所と、前記裏板部４に向き合う箇所とにそれぞれ、被案内部１１ｈが形成されている。図示の例では、かかる被案内部１１ｈは、短寸の円柱状を呈している。 Further, in the illustrated example, guided portions 11 h are respectively formed at a location facing the front plate portion 3 and a location facing the back plate portion 4 in the free end 11 a of the movable arm portion 11. In the illustrated example, the guided portion 11h has a short cylindrical shape.
　そして、図示の例では、外側パーツＦ内に前記のように内側パーツＭを納めるにあたり、外側パーツＦの前記中心線ｘを挟んだ左右においてそれぞれ、前記表板部３に形成された案内溝９にこの側に形成された被案内部１１ｈが入り込み、前記裏板部４に形成された案内溝９にこの側に形成された被案内部１１ｈが入り込み、これにより外側パーツＦと内側パーツＭとが組み合わされるようになっている。内側パーツＭは被案内部１１ｈを案内溝９に納めた状態では常時左右の可動腕部１１、１１を内向きに弾性変形させており、（図２）また、外側パーツＦの前記中心線ｘに基部１０を沿わせた状態でこの中心線ｘに沿って移動されるようになっている。 In the illustrated example, when the inner part M is accommodated in the outer part F as described above, the guide grooves 9 formed in the front plate portion 3 on the left and right sides of the center line x of the outer part F, respectively. The guided portion 11h formed on this side enters, and the guided portion 11h formed on this side enters the guide groove 9 formed on the back plate portion 4, whereby the outer part F and the inner part M Are to be combined. The inner part M always elastically deforms the left and right movable arm parts 11 and 11 inwardly with the guided part 11h in the guide groove 9 (FIG. 2), and the center line x of the outer part F In this state, the base 10 is moved along the center line x.
　図示の例では、前記表板部３側の被案内部１１ｈの先端と前記裏板部４側の被案内部１１ｈの先端との間の距離が、表板部３の案内溝９の溝底と裏板部４の前記導入溝４ａの溝底との間の距離よりもやや大きくなるようにしてある。これにより、図示の例では、外側パーツＦ内へ前記のように内側パーツＭを納めるにあたり、導入溝４ａを被案内部１１ｈが通過するまでの間は主として外側パーツＦの第一張り出し部６を外側に撓み出させてこの納め入れを許容させるようになっている。そして、かかる導入溝４ａを被案内溝９が通過した段階での第一張り出し部６の撓み戻しにより、裏板部４の案内溝９から被案内部１１ｈが抜け出さない状態を作り出して、外側パーツＦと内側パーツＭとを分離しないように組み合わせている。（図３） In the illustrated example, the distance between the tip of the guided portion 11 h on the front plate portion 3 side and the tip of the guided portion 11 h on the back plate portion 4 side is the groove bottom of the guide groove 9 of the front plate portion 3. And the distance between the bottom of the back plate portion 4 and the groove bottom of the introduction groove 4a. Thus, in the illustrated example, when the inner part M is accommodated in the outer part F as described above, the first overhang part 6 of the outer part F is mainly used until the guided part 11h passes through the introduction groove 4a. It is designed to allow this accommodation by bending outward. And the state where the guided part 11h does not come out from the guide groove 9 of the back plate part 4 is created by bending back of the first projecting part 6 when the guided groove 9 passes through the introduction groove 4a. F and the inner part M are combined so as not to be separated. (Figure 3)
　そして、この実施の形態にあっては、前記案内溝９と被案内部１１ｈとによって、前記紐状体Ｃｄに対する前記第二開口部２から引き出される向きへの張力の作用により所定位置より前記第二開口部２側に内側パーツＭが近づくに連れて、前記自由端１１ａと前記留め付け用内壁５ａとの間の距離を漸減させる前記可動腕部１１の可動がなされるようになっている。 In this embodiment, the guide groove 9 and the guided portion 11h cause the tension from the second opening 2 to be pulled out from the second opening 2 with respect to the string-like body Cd. As the inner part M approaches the two openings 2 side, the movable arm portion 11 that gradually decreases the distance between the free end 11a and the fastening inner wall 5a is made movable.
　図示の例では、外側パーツＦの留め付け用内壁５ａと内側パーツＭの可動腕部１１の自由端１１ａとの間に、前記案内溝９の長さ方向中程の位置に被案内部１１ｈを位置させた所定位置において、留め付け用内壁５ａと爪部１１ｃの爪先との間の距離よりも太さを太くする紐状体Ｃｄを通過させた場合、内側パーツＭが前記所定位置にあるときは前記爪部１１ｃが紐状体Ｃｄに食い込みコードロックが紐状体Ｃｄに留め付くようになっている。（図４／基準状態）この状態から、紐状体Ｃｄに前記第二開口部２から引き出される向きの張力を作用させると、より具体的には、外側パーツＦを固定させた状態で紐状体Ｃｄにおける第二開口部２から引き出されている箇所に引っ張り力を作用させると、爪部１１ｃを紐状体Ｃｄに食い込ませている内側パーツＭは第二開口部２側に移動されながら、自由端１１ａを留め付け用内壁５ａから離す向きに可動され案内溝９における前記中心線ｘ側に位置される溝壁９ｃに被案内部１１ｈを押し当てさせる。ここで、この中心線ｘ側に位置される溝壁９ｃは前記第三線分ｙ３と前記第一線分ｙ１の外側にあって前記中心線ｘに直交する仮想の第四線分ｙ４との間において、この第三線分ｙ３に近づくに連れて次第に前記中心線ｘとの距離を大きくさせるように傾斜していることから、内側パーツＭが第二開口部２に近づけば近づくほど可動腕部１１は中心線ｘから離れる向きに撓んで前記自由端１１ａと前記留め付け用内壁５ａとの間の距離は漸減し、したがって紐状体Ｃｄに爪部１１ｃがより強固に突き立てられる。 In the example shown in the figure, a guided portion 11h is provided at a position in the middle of the length direction of the guide groove 9 between the inner wall 5a for fastening the outer part F and the free end 11a of the movable arm portion 11 of the inner part M. When the string-like body Cd having a thickness larger than the distance between the inner wall 5a for fastening and the claw tip of the claw portion 11c is passed at the predetermined position, the inner part M is at the predetermined position. The claw portion 11c bites into the string-like body Cd, and the cord lock is fastened to the string-like body Cd. (FIG. 4 / reference state) From this state, when the tension in the direction pulled out from the second opening 2 is applied to the string-like body Cd, more specifically, the string-like form with the outer part F fixed. When a pulling force is applied to a portion pulled out from the second opening 2 in the body Cd, the inner part M that bites the claw portion 11c into the string-like body Cd is moved to the second opening 2 side, The guided portion 11h is pressed against the groove wall 9c which is moved in a direction to move the free end 11a away from the fastening inner wall 5a and is located on the center line x side in the guide groove 9. Here, the groove wall 9c positioned on the center line x side is between the third line segment y3 and a virtual fourth line segment y4 that is outside the first line segment y1 and orthogonal to the center line x. In this case, the movable arm portion 11 is inclined so as to gradually increase the distance from the center line x as it approaches the third line segment y3. Is bent away from the center line x, and the distance between the free end 11a and the inner wall 5a for fastening is gradually reduced, so that the claw portion 11c is more firmly projected on the string-like body Cd.
　これにより、この実施の形態にあっては、前記紐状体Ｃｄに対して前記第二開口部２から引き出される向きへの張力が作用されたときには、かかる紐状体Ｃｄに対する留め付け用内壁５ａと可動腕部１１の自由端１１ａとの間での挟持状態を内側パーツＭの第二開口部２側への移動を通じて強化することができ、この向きへの紐状体Ｃｄの抜け出しを効果的に阻止するようになっている。（図５／ロック状態） Thereby, in this embodiment, when the tension | tensile_strength in the direction pulled out from said 2nd opening part 2 is acted with respect to the said string-like body Cd, the inner wall 5a for fastening with respect to this string-like body Cd And the free end 11a of the movable arm portion 11 can be strengthened by moving the inner part M toward the second opening 2 side, and the string-like body Cd can be effectively pulled out in this direction. It is supposed to stop. (Figure 5 / locked state)
　また、この実施の形態にあっては、前記案内溝９と被案内部１１ｈとによって、紐状体Ｃｄに対する第一開口部１から引き出される向きへの張力の作用により所定位置より第一開口部１側に内側パーツＭが近づくに連れて、自由端１１ａと留め付け用内壁５ａとの間の距離を漸増させる前記可動腕部１１の可動がなされるようになっている。 In this embodiment, the guide groove 9 and the guided portion 11h cause the first opening portion from a predetermined position by the action of the tension in the direction of being pulled out from the first opening portion 1 with respect to the string-like body Cd. As the inner part M approaches the one side, the movable arm portion 11 that gradually increases the distance between the free end 11a and the fastening inner wall 5a is made movable.
　図示の例では、内側パーツＭが前記所定位置にある状態（図４／基準状態）から、紐状体Ｃｄに前記第一開口部１から引き出される向きの張力を作用させると、より具体的には、外側パーツＦを固定させた状態で紐状体Ｃｄにおける第一開口部１から引き出されている箇所に引っ張り力を作用させると、爪部１１ｃを紐状体Ｃｄに食い込ませている内側パーツＭは第一開口部１側に移動されながら、案内溝９における前記留め付け用内壁５ａ側に位置される溝壁９ｄに被案内部１１ｈを押し当てさせる。ここで、この留め付け用内壁５ａ側に位置される溝壁９ｄは、前記第三線分ｙ３と前記第一線分ｙ１のやや外側となる箇所との間において、この第一線分ｙ１側に近づくに連れて次第に前記中心線ｘとの距離を小さくさせるように傾斜していることから、内側パーツＭが第一開口部１に近づけば近づくほど可動腕部１１は中心線ｘに近づく向きに撓んで前記自由端１１ａと前記留め付け用内壁５ａとの間の距離は漸増し、したがって紐状体Ｃｄへの爪部１１ｃの突き立て力は弱められる。また、図示の例では、かかる爪部１１ｃにおける前記第二開口部２側に向けられる厚さ側側面１１ｅは前記傾斜面１１ｇとなっていることから、紐状体Ｃｄに前記第一開口部１から引き出される向きの張力が作用されるときは、この傾斜面１１ｇの傾斜により爪部１１ｃは紐状体Ｃｄから抜け出し易くなる。 In the illustrated example, more specifically, when the tension in the direction pulled out from the first opening 1 is applied to the string-like body Cd from the state in which the inner part M is in the predetermined position (FIG. 4 / reference state).

While M moves to the first opening 1 side, the guided portion 11h is pressed against the groove wall 9d positioned on the inner wall 5a for fastening in the guide groove 9. Here, the groove wall 9d positioned on the side of the fastening inner wall 5a is located on the first line segment y1 side between the third line segment y3 and a portion slightly outside the first line segment y1. Since it is inclined so as to gradually decrease the distance from the center line x as it approaches, the movable arm portion 11 approaches the center line x as the inner part M approaches the first opening 1. The distance between the free end 11a and the fastening inner wall 5a is gradually increased, so that the thrusting force of the claw portion 11c on the string-like body Cd is weakened. Further, in the illustrated example, the thickness side surface 11e directed to the second opening 2 side in the claw portion 11c is the inclined surface 11g. When the tension in the direction of being pulled out is applied, the claw portion 11c is easily pulled out of the string-like body Cd due to the inclination of the inclined surface 11g.
　これにより、この実施の形態にあっては、前記紐状体Ｃｄに対して前記第一開口部１から引き出される向きへの張力が作用されたときには、かかる紐状体Ｃｄに対する留め付け用内壁５ａと可動腕部１１の自由端１１ａとの間での挟持状態を内側パーツＭの第一開口部１側への移動を通じて弱化することができ、この向きへは紐状体Ｃｄを所望の長さ分引き出せるようになっている。（図６／調整状態） Thereby, in this embodiment, when the tension | tensile_strength in the direction pulled out from said 1st opening part 1 is acted with respect to the said string-like body Cd, the inner wall 5a for fastening with respect to this string-like body Cd And the free end 11a of the movable arm portion 11 can be weakened through movement of the inner part M toward the first opening 1 side, and the string-like body Cd can have a desired length in this direction. It can be pulled out. (Fig. 6 / Adjustment state)
