さらにばね部４２は、フック部３２が樹脂で一体に成形された工程では、フック部３２の端部３２ｂの外側に位置し、先端部４２ｂに近づくほどフック部３２の端部３２ｂから離れる方向に傾斜して延出し、先端部４２ｂがフック部３２の端部３２ｂから離れている。この後、連結具１０を組み立てる工程で、ばね部４２の基端部４２ａを弾性変形させて、フック部３２の端部３２ｂの内側に入れる。先端部４２ｂがフック部３２の端部３２ｂに当接し、内側から当たる方向に付勢力が働く。この状態で、ばね部４２の外側面４２ｃを外側から押すと、基端部４２ａが弾性変形して先端部４２ｂがフック部３２の端部３２ｂから離れ、挿通口４０が開放される。押す力を解除すると、ばね部４２は弾性力で復元してフック部３２の端部３２ｂに当接し、挿通口４０が閉鎖される。 Further, the spring portion 42 is located outside the end portion 32b of the hook portion 32 in the process in which the hook portion 32 is integrally molded with resin, and the spring portion 42 moves away from the end portion 32b of the hook portion 32 toward the tip end portion 42b. The tip portion 42b is inclined and extends, and the tip portion 42b is separated from the end portion 32b of the hook portion 32. After that, in the step of assembling the connecting tool 10, the base end portion 42a of the spring portion 42 is elastically deformed and put inside the end portion 32b of the hook portion 32. The tip portion 42b comes into contact with the end portion 32b of the hook portion 32, and an urging force acts in a direction of hitting from the inside. When the outer side surface 42c of the spring portion 42 is pushed from the outside in this state, the base end portion 42a is elastically deformed, the tip end portion 42b is separated from the end portion 32b of the hook portion 32, and the insertion opening 40 is opened. When the pushing force is released, the spring portion 42 is restored by the elastic force and contacts the end portion 32b of the hook portion 32, and the insertion opening 40 is closed.

フック部３２の端部３２ａには、板部３６付近を覆う筒状のカバー４６が設けられている。カバー４６は、一対の板部３６を覆う互いに平行な一対の側面４６ａと、一対の側面４６ａの側縁部同士を連結しフック部３２の外側面を覆う外側面４６ｂと、一対の側面４６ａの、外側面４６ｂと反対側の側縁部同士を連結する連結部４６ｃで形成された筒状である。側面４６ａの形状は、板部３６とほぼ等しく、フック部３２に取り付けた時にフランジ部２８に接する直線状の端部と、この端部に連続する湾曲した側縁部と、直線状の端部の反対側に位置して凹状に湾曲した端部で囲まれて形成されている。一対の側面４６ａは、ばね部４２の両側に位置し、ばね部４２が挿通口４０を開閉する弾性変形の方向と平行に対面し、ばね部４２が一対の側面４６ａの間を弾性変形する際に、ばね部４２が挿通口４０を開閉する弾性変形の方向に沿ってその揺動方向をガイドする。従って、ばね部４２は、一対の側面４６ａによって、挿通口４０を開閉する方向にのみ弾性変形するようにその動作範囲が規制される。 At the end portion 32 a of the hook portion 32, a cylindrical cover 46 that covers the vicinity of the plate portion 36 is provided. The cover 46 includes a pair of parallel side surfaces 46a that covers the pair of plate portions 36, an outer surface 46b that connects side edge portions of the pair of side surfaces 46a and covers an outer surface of the hook portion 32, and a pair of side surfaces 46a. The outer surface 46b has a tubular shape formed by a connecting portion 46c that connects the side edge portions on the opposite side. The shape of the side surface 46a is substantially the same as that of the plate portion 36, and a linear end portion that contacts the flange portion 28 when attached to the hook portion 32, a curved side edge portion continuous to this end portion, and a linear end portion. It is located on the opposite side of and is surrounded by an end curved in a concave shape. The pair of side surfaces 46a are located on both sides of the spring portion 42, face the spring portion 42 in parallel with the elastic deformation direction of opening and closing the insertion opening 40, and when the spring portion 42 elastically deforms between the pair of side surfaces 46a. In addition, the spring portion 42 guides the swinging direction along the elastic deformation direction in which the insertion opening 40 is opened and closed. Therefore, the operating range of the spring portion 42 is restricted by the pair of side surfaces 46 a so as to elastically deform only in the direction in which the insertion opening 40 is opened and closed.

外側面４６ｂは、側面４６ａの直線状の端部に連続する直線状の端部を有し、この端部と反対側の端部は、側面４６ａの、凹状に湾曲した端部に繋がっている。外側面４６ｂの反対側に位置した連結部４６ｃは、一対の側面４６ａを連結する細い直線の棒状であり、側面４６ａの、湾曲した側縁部と湾曲して傾斜する端部から図面上の斜め下方に突出する角部分に繋がっている。連結部４６ｃの下面は、外側面４６ｂの長く突出した方の端部の延長線上に位置している。連結部４６ｃと、一対の側面４６ａに囲まれた矩形の空間は、操作用窓部４８となる。また、カバー４６の内側面には、本体１４に係止される図示しない係止部が設けられている。 The outer side surface 46b has a linear end that is continuous with the linear end of the side surface 46a, and the end opposite to this end is connected to the concavely curved end of the side surface 46a. .. The connecting portion 46c located on the opposite side of the outer side surface 46b is a thin straight rod shape that connects the pair of side surfaces 46a, and is oblique from the end portion of the side surface 46a that is curved and inclined from the curved side edge portion in the drawing. It is connected to the corner that projects downward. The lower surface of the connecting portion 46c is located on the extension line of the end portion of the outer side surface 46b that projects longer. A rectangular space surrounded by the connecting portion 46c and the pair of side surfaces 46a serves as an operation window portion 48. In addition, a lock portion (not shown) that is locked to the main body 14 is provided on the inner surface of the cover 46.

カバー４６をフック部３２に取り付けた時、操作用窓部４８はフランジ部２８に繋がるものであり、操作用窓部４８にばね部４２の外側面４２ｃが露出する。連結部４６ｃは、ばね部４２の外側面４２ｃの一部を外側から覆うように位置する。これにより、ばね部４２に内側から強い力が加えられた時、外側面４２ｃが連結部４６ｃに当接するため、先端部４２ｂが端部３２ｂを乗り越えてばね部４２がフック部３２の外側に向けて変形することを制限する。また、連結部４６ｃとフック部３２の端部３２ｂの間の空間が、挿通口４０となる。さらに、連結部４６ｃは、操作用窓部４８から露出するばね部４２と挿通口４０とを分断する。連結部４６ｃの、側面４６ａに連続する一対の端部は、一対の板部３６の係合突起３８の外側に弾性変形させて嵌装し、係止される。これにより、カバー４６がフランジ部２８と反対側に移動することを防ぐ。なお、カバー４６はフランジ部２８よりも内径が小さく、装着状態でフランジ部２８側へも移動することがない。カバー４６の側面４６ａの、湾曲した側縁部と湾曲して傾斜する端部は、板部３６の端部３６ａと側縁部３６ｂに沿って取り付けられる。このように、カバー４６をフック部３２に取り付けた時、ばね部４２は、一対の側面４６ａによって挿通口４０を開閉する方向にのみ弾性変形するようにその動作範囲が規制されるとともに、連結部４６ｃによってばね部４２の開放と閉鎖を切り替える方向の変形範囲が制限される。 When the cover 46 is attached to the hook portion 32, the operation window portion 48 is connected to the flange portion 28, and the outer side surface 42c of the spring portion 42 is exposed at the operation window portion 48. The connecting portion 46c is located so as to cover a part of the outer side surface 42c of the spring portion 42 from the outside. Accordingly, when a strong force is applied to the spring portion 42 from the inside, the outer side surface 42c contacts the connecting portion 46c, so that the tip end portion 42b passes over the end portion 32b and the spring portion 42 is directed toward the outside of the hook portion 32. To limit deformation. Further, the space between the connecting portion 46c and the end portion 32b of the hook portion 32 serves as the insertion port 40. Further, the connecting portion 46c separates the spring portion 42 exposed from the operation window portion 48 from the insertion opening 40. A pair of end portions of the connecting portion 46c, which are continuous with the side surface 46a, are elastically deformed and fitted to the outside of the engaging protrusions 38 of the pair of plate portions 36, and locked. This prevents the cover 46 from moving to the side opposite to the flange portion 28. The cover 46 has an inner diameter smaller than that of the flange portion 28, and does not move toward the flange portion 28 side in the mounted state. An end portion of the side surface 46a of the cover 46, which is curved and inclined with respect to the curved side edge portion, is attached along the end portion 36a and the side edge portion 36b of the plate portion 36. Thus, when the cover 46 is attached to the hook portion 32, the operating range of the spring portion 42 is regulated by the pair of side surfaces 46a so as to be elastically deformed only in the direction in which the insertion opening 40 is opened and closed, and the connecting portion is 46c limits the range of deformation of the spring portion 42 in the direction of switching between opening and closing.

次に、この実施形態の連結具１０の組立方法について説明する。フック部３２は、樹脂で一体に成形された工程で端部３２ｂの外側に位置しているばね部４２を、ばね部４２の基端部４２ａを弾性変形させてフック部３２の端部３２ｂの側方から回して端部３２ｂの内側に入れる。この状態で、先端部４２ｂがフック部３２の端部３２ｂに当接し、内側から当たる方向に付勢力が働く。ばね部４２の先端部４２ｂは、フック部３２の端部３２ｂの切欠部３４の内側に嵌合されてフック部３２の内側面に連続する。 Next, a method of assembling the connector 10 of this embodiment will be described. The hook portion 32 elastically deforms the base end portion 42a of the spring portion 42 of the spring portion 42 located outside the end portion 32b in the step of integrally molding the resin, and the spring portion 42 of the end portion 32b of the hook portion 32 is formed. Turn it from the side and put it inside the end 32b. In this state, the tip portion 42b comes into contact with the end portion 32b of the hook portion 32, and an urging force acts in a direction of hitting from the inside. The tip portion 42b of the spring portion 42 is fitted inside the cutout portion 34 of the end portion 32b of the hook portion 32 and is continuous with the inner surface of the hook portion 32.

次に、リング部１２の係止孔２０に、フック部３２のフランジ部２６をベルト掛け１６の反対側から強い力で押し込む。係止孔２０よりもフランジ部２６の方が大きいため通過しないが、一定以上の力を加えるとリング部１２の保持部１８が弾性変形してスリット２２が広がり、係止孔２０の内径が広がり、通過可能となる。フランジ部２６が通過した後は弾性変形が戻り、フランジ部２６が係止されて抜け落ちず、リング部１２とフック部３２が取り付けられ、本体１４となる。フック部３２は、一対のフランジ部２６，２８の間の軸部２４をリング部１２の係止孔２０に回転可能に保持され、抜けることがない。 Next, the flange portion 26 of the hook portion 32 is pushed into the locking hole 20 of the ring portion 12 from the opposite side of the belt hook 16 with a strong force. Since the flange portion 26 is larger than the locking hole 20, it does not pass, but when a certain force or more is applied, the holding portion 18 of the ring portion 12 elastically deforms and the slit 22 expands, and the inner diameter of the locking hole 20 expands. , Will be able to pass. After the flange portion 26 passes, the elastic deformation returns, the flange portion 26 is locked and does not fall out, and the ring portion 12 and the hook portion 32 are attached to form the main body 14. The hook portion 32 rotatably holds the shaft portion 24 between the pair of flange portions 26 and 28 in the locking hole 20 of the ring portion 12 and does not come off.

次に、カバー４６を本体１４に取り付ける。取付方法は、ばね部４２を押して弾性変形させ、開放した挿通口４０にカバー４６を、連結部４６ｃとは反対側の端からフック部３２に通し、移動させながらフランジ部２８に近づける。すると、カバー４６または板部３６が弾性変形し、カバー４６の内側面に係合突起３８が差し込まれ、弾性変形が戻り、カバー４６が本体１４に取り付けられる。カバー４６は、フランジ部２８と係合突起３８に保持されて、移動することがない。 Next, the cover 46 is attached to the main body 14. As for the mounting method, the spring portion 42 is pressed to elastically deform it, and the cover 46 is inserted into the opened insertion opening 40 from the end opposite to the connecting portion 46c through the hook portion 32, and is brought closer to the flange portion 28 while moving. Then, the cover 46 or the plate portion 36 elastically deforms, the engaging projection 38 is inserted into the inner surface of the cover 46, the elastic deformation returns, and the cover 46 is attached to the main body 14. The cover 46 is held by the flange portion 28 and the engagement protrusion 38 and does not move.

次に、リング部１２に、ベルトや肩紐等の幅広の長尺部材を取り付ける。長尺部材を、リング部１２のベルト掛け１６と保持部１８の間の開口部に端部を差し込み、ベルト掛け１６を巻き回して折り返し、バックルやカン等で取り付ける。フック部３２には、他の被掛止体、例えばカバンや、水筒等の小物を取り付ける。まず、カバー４６の操作用窓部４８から露出しているばね部４２の外側面４２ｃを内側に向かって押す。するとばね部４２の基端部４２ａが弾性変形し、ばね部４２の先端部４２ｂが、フック部３２の端部３２ｂから離れて、挿通口４０が開放される。開放した挿通口４０から、フック部３２に被掛止体を通し、押す力を解除して、ばね部４２の弾性変形を復元して挿通口４０を閉鎖する。ばね部４２の先端部４２ｂと、フック部３２の端部３２ｂは小さい面積で互いに当接して閉鎖しているが、ばね部４２は一対の板部３６の内側面にわずかなゆとりを有して嵌合されているため、ばね部４２が弾性変形する際にずれることがなく、確実にフック部３２の端部３２ｂに再び当接して閉鎖される。ばね部４２の先端部４２ｂに、フック部３２の端部３２ｂの側方へずれるような力が加えられると、板部３６が押されて弾性変形して、ばね部４２の先端部４２ｂが端部３２ｂから外れる恐れがあるが、板部３６の外側にはカバー４６が取り付けられているため板部３６の弾性変形を防ぎ、ばね部４２が外れることがない。不用意に挿通口４０が開放されることがない。被掛止体が不要となった時は、同じ操作で外す。 Next, a wide long member such as a belt or a shoulder strap is attached to the ring portion 12. The end of the long member is inserted into the opening between the belt hook 16 and the holding portion 18 of the ring portion 12, the belt hook 16 is wound and folded back, and attached by a buckle or a can. Other hooked objects, such as a bag and a water bottle, are attached to the hook portion 32. First, the outer surface 42c of the spring portion 42 exposed from the operation window portion 48 of the cover 46 is pushed inward. Then, the base end portion 42a of the spring portion 42 is elastically deformed, the tip end portion 42b of the spring portion 42 is separated from the end portion 32b of the hook portion 32, and the insertion opening 40 is opened. The hooked body is passed through the hooked portion 32 through the opened insertion opening 40, the pushing force is released, the elastic deformation of the spring portion 42 is restored, and the insertion opening 40 is closed. The tip end portion 42b of the spring portion 42 and the end portion 32b of the hook portion 32 are in close contact with each other with a small area, but the spring portion 42 has a slight allowance on the inner side surfaces of the pair of plate portions 36. Since the spring portion 42 is fitted, the spring portion 42 does not shift when elastically deformed, and surely comes into contact with the end portion 32b of the hook portion 32 again to be closed. When a force is applied to the tip end portion 42b of the spring portion 42 to the side of the end portion 32b of the hook portion 32, the plate portion 36 is pressed and elastically deformed, and the tip end portion 42b of the spring portion 42 ends. Although there is a possibility that it will come off from the portion 32b, since the cover 46 is attached to the outside of the plate portion 36, elastic deformation of the plate portion 36 is prevented, and the spring portion 42 does not come off. The insertion opening 40 will not be opened carelessly. When the hooked object is no longer needed, remove it with the same operation.

この実施形態の連結具１０によれば、一対の被掛止体を、高い取り付け強度で連結することができる。一方の被掛止体が取り付けられるリング部１２と、他方の被掛止体を吊り下げるフック部３２は、高い取り付け強度で取り付けられており、被掛止体に引き離す方向へ力が加えられても、外れることがない。また、被掛止体に捻じるような力が加えられても、不用意に連結が解除されることを防ぐものである。フック部３２の挿通口４０には、挿通口４０を弾性変形により開閉するばね部４２が、カバー４６に一部が覆われて設けられ、ばね部４２は、開閉する方向にのみ弾性変形するようにカバー４６により規制され、被掛止体を着脱する時は簡単に開放され、その他の時は確実に閉鎖され、安全に連結を維持することができる。 According to the connecting tool 10 of this embodiment, the pair of hooked members can be connected with high attachment strength. The ring portion 12 to which the one to-be-held body is attached and the hook portion 32 that suspends the other to-be-held body are attached with high attachment strength, and a force is applied to the to-be-held body in the direction of separating them. However, it does not come off. Further, even if a force such as a twist is applied to the hooked body, the connection is prevented from being accidentally released. A spring portion 42 that opens and closes the insertion opening 40 by elastic deformation is provided in the insertion opening 40 of the hook portion 32 with a part covered by a cover 46, and the spring portion 42 is elastically deformed only in the opening and closing direction. It is regulated by the cover 46 and is easily opened when the hooked body is attached or detached, and is securely closed at other times, so that the connection can be safely maintained.

その他、カバー４６の操作用窓部４８から、ばね部４２の外側面４２ｃが露出しているため、外側面４２ｃを押して挿通口４０が簡単に開放され、被掛止体をフック部３２に着脱する操作が容易である。 In addition, since the outer side surface 42c of the spring portion 42 is exposed from the operation window 48 of the cover 46, the outer side surface 42c is pressed to easily open the insertion port 40, and the hooked body is attached to and detached from the hook portion 32. It is easy to do.

連結具１０は簡単な構造で、いろいろな用途に使用することができ、ベルトや肩紐など幅広の長尺部材に、高い取り付け強度でカバン等、所望の被掛止体を吊り下げて連結することができる。長尺部材が取り付けられるリング部１２と、別部材を吊り下げるフック部３２は、フック部３２のフランジ部２６がリング部１２の保持部１８に保持されて高い取り付け強度で取り付けられており、重いカバンを吊り上げることができる。カバンを保持して運搬する時は、ばね部４２がカバー４６に保護され、不用意に弾性変形することがなく、確実に挿通口４０を閉鎖して安全である。特に、カバンを下ろしたり、再び持ち上げたりする際に、フック部３２とカバンに捻じるような方向に力が加えられても、ばね部４２がフック部３２の外側に外れることがなく、不用意に連結が解除する恐れがなく、安全である。 The connecting tool 10 has a simple structure and can be used for various purposes. A desired long-held member such as a belt or shoulder strap is hung and connected with a desired hooked body such as a bag with high attachment strength. be able to. The ring portion 12 to which the long member is attached and the hook portion 32 for suspending another member are heavy because the flange portion 26 of the hook portion 32 is held by the holding portion 18 of the ring portion 12 with high attachment strength. The bag can be lifted. When the bag is held and transported, the spring portion 42 is protected by the cover 46 and is not elastically deformed accidentally, and the insertion opening 40 is surely closed to ensure safety. In particular, when the bag is lowered or lifted again, even if a force is applied to the hook portion 32 and the bag in a twisting direction, the spring portion 42 does not come off to the outside of the hook portion 32, and careless It is safe because there is no risk of disconnection.

また、本体１４は、軸部２４がリング部１２の係止孔２０の内側に回転可能に挿通されているため、フック部３２はリング部１２に対して軸周りに回転可能であり、カバンが肩ひもに対して回転する。このため、カバンが身体の動きに追従して円滑に移動し、身体の動きを妨げることがなく、歩行や走行が容易である。またカバンを下ろしたり持ち上げたりする際も、肩紐がねじれることがなく、使いやすいものである。フック部３２の端部３２ｂには、厚みが半分になった切欠部３４が形成され、ばね部４２の先端部４２ｂが切欠部３４に嵌合されて、フック部３２の内側面にほぼ連続する形状となり、段差が無いため、フック部３２に取り付けた掛止体が自由に角度を変えることができる。 Further, in the main body 14, since the shaft portion 24 is rotatably inserted inside the locking hole 20 of the ring portion 12, the hook portion 32 is rotatable about the axis with respect to the ring portion 12, and the bag is Rotate against shoulder straps. For this reason, the bag moves smoothly following the movement of the body, does not hinder the movement of the body, and is easy to walk or run. Also, when the bag is lowered or lifted, the shoulder straps are not twisted and are easy to use. A cutout portion 34 having a half thickness is formed at the end portion 32b of the hook portion 32, and the tip end portion 42b of the spring portion 42 is fitted into the cutout portion 34 and is substantially continuous with the inner surface of the hook portion 32. Since it has a shape and has no step, the hook body attached to the hook portion 32 can freely change the angle.

The spring portion 60 is a rod-shaped member provided on the major axis of the flange portion 26 at a position close to the end portion on the opposite side to the shaft portion 52, and in the same direction as the flange portion 26 from the flange portion 26. The hooks 32 extend toward the inner side surface of the end portion 32b of the hook portion 32 while increasing the distance a little. The spring portion 60 has a rectangular cross-sectional shape that intersects in the longitudinal direction, has a narrow width between the inner surface and the outer surface that is continuous with the hook portion 32, and has a shape that easily elastically deforms as a whole. Become. A portion of the spring portion 60 facing the engagement protrusion 58 is bent outward in a U-shape to provide an operation protrusion 62. The operation projection 62 is provided so as to be curved so as not to interfere with the engagement projection 58, and serves as the operation projection 62 that elastically deforms the spring portion 60. A through hole 65 into which the insertion protrusion 33 formed at the end portion 32b of the hook portion 32 is inserted is provided in the tip portion 60a of the spring portion 60.

ばね部６０は、フック部３２が樹脂で一体に成形された工程では、フック部３２の外側に位置し、先端部６０ａに近づくほどフック部３２の端部３２ｂから離れる方向に傾斜して延出し、先端部６０ａがフック部３２の端部３２ｂから離れている。この後、連結具５０を組み立てる工程で、ばね部６０を弾性変形させてフック部３２の端部３２ｂの内側に入れる。先端部６０ａがフック部３２の端部３２ｂに当接し、内側から当たる方向に付勢力が働く。ばね部６０の先端部６０ａは、フック部３２の端部３２ｂの切欠部３４の内側に嵌合されてフック部３２の内側面に連続し、また先端部６０ａの透孔６５には、端部３２ｂの差込突起３３が差し込まれる。この状態で、ばね部６０の操作用突起６２を外側から押すと、ばね部６０全体が弾性変形して先端部６０ａがフック部３２の端部３２ｂから離れ、挿通口４０が開放される。押す力を解除すると、ばね部６０は弾性力で復元してフック部３２の端部３２ｂに当接し、挿通口４０が閉鎖される。 The spring portion 60 is located outside the hook portion 32 in the process in which the hook portion 32 is integrally molded with resin, and extends in a direction inclined away from the end portion 32b of the hook portion 32 as it approaches the tip portion 60a. The tip portion 60a is separated from the end portion 32b of the hook portion 32. After that, in the process of assembling the connector 50, the spring portion 60 is elastically deformed and put inside the end portion 32b of the hook portion 32. The tip portion 60a comes into contact with the end portion 32b of the hook portion 32, and a biasing force acts in a direction of hitting from the inside. The tip portion 60a of the spring portion 60 is fitted inside the cutout portion 34 of the end portion 32b of the hook portion 32 and is continuous with the inner side surface of the hook portion 32, and the through hole 65 of the tip portion 60a has an end portion. The insertion protrusion 33 of 32b is inserted. When the operating projection 62 of the spring portion 60 is pushed from the outside in this state, the entire spring portion 60 is elastically deformed, the tip portion 60a is separated from the end portion 32b of the hook portion 32, and the insertion opening 40 is opened. When the pushing force is released, the spring portion 60 is restored by the elastic force and comes into contact with the end portion 32b of the hook portion 32, and the insertion opening 40 is closed.

軸部５２の、フック部３２の端部３２ａ近傍には、ばね部６０の一部を覆う筒状のカバー４６が設けられている。軸部５２のフランジ部２６に近い部分には、組立状態でリング部１２が取り付けられ、カバー４６は、リング部１２とフック部３２の間に取り付けられるものである。カバー４６は、軸部５２とばね部６０に渡されて両側を覆う互いに平行な一対の側面４６ａと、一対の側面４６ａの側縁部同士を連結しフック部３２の外側面を覆う外側面４６ｂと、一対の側面４６ａの、外側面４６ｂと反対側の側縁部同士を連結する連結部４６ｃで形成された筒状体である。一対の側面４６ａは、ばね部６０が一対の側面４６ａの間を弾性変形する際に、ばね部６０が挿通口４０を開閉する弾性変形の方向に沿ってその揺動方向をガイドする。側面４６ａの形状は略矩形であり、軸部５２に取り付けた時にリング部１２に接する直線の端部と、この端部に連続する湾曲した側縁部と、直線の端部の反対側に位置する傾斜した直線の端部で囲まれて形成されている。 A tubular cover 46 that covers a part of the spring portion 60 is provided near the end portion 32 a of the hook portion 32 of the shaft portion 52. The ring portion 12 is attached to a portion of the shaft portion 52 near the flange portion 26 in an assembled state, and the cover 46 is attached between the ring portion 12 and the hook portion 32. The cover 46 is provided with a pair of parallel side surfaces 46 a that are passed over the shaft portion 52 and the spring portion 60 and cover both sides thereof, and an outer surface 46 b that connects the side edge portions of the pair of side surfaces 46 a and covers the outer surface of the hook portion 32. And a cylindrical body formed by a connecting portion 46c that connects side edges of the pair of side surfaces 46a opposite to the outer surface 46b. When the spring portion 60 elastically deforms between the pair of side surfaces 46a, the pair of side surfaces 46a guides the swinging direction along the elastic deformation direction in which the spring portion 60 opens and closes the insertion opening 40. The side surface 46a has a substantially rectangular shape, and has a linear end portion that comes into contact with the ring portion 12 when attached to the shaft portion 52, a curved side edge portion that is continuous with this end portion, and is located on the opposite side of the linear end portion. It is formed so as to be surrounded by the end of the inclined straight line.

外側面４６ｂは、側面４６ａの直線状の端部に連続する直線状の端部を有し、この端部と反対側の端部は、側面４６ａの、傾斜した直線の端部よりも後述するフランジ部７０側に位置し、直線状に形成されている。 The outer side surface 46b has a linear end portion that is continuous with the linear end portion of the side surface 46a, and the end portion opposite to this end portion will be described later than the inclined straight end portion of the side surface 46a. It is located on the side of the flange portion 70 and is linearly formed.

連結部４６ｃは、一対の側面４６ａを連結する細い直線の棒状であり、側面４６ａの、湾曲した側縁部と傾斜する端部で囲まれた角部分に連結されている。連結部４６ｃと、一対の側面４６ａに囲まれた矩形の空間は、操作用窓部６６となる。カバー４６の、リング部１２に接する端部には、一対の側面４６ａ、外側面４６ｂ、操作用窓部６６にわたって、側方に突出するフランジ部７０が一周して設けられている。フランジ部７０の、リング部１２側の面には、リング部１２の保持部１８に形成された係止孔２０に嵌合される半円筒部６８が設けられている。半円筒部６８は、操作用窓部６６の反対側が切り欠かれている。 The connecting portion 46c has a thin linear rod shape that connects the pair of side surfaces 46a, and is connected to a corner portion of the side surface 46a surrounded by the curved side edge portion and the inclined end portion. A rectangular space surrounded by the connecting portion 46c and the pair of side surfaces 46a serves as an operation window portion 66. At the end of the cover 46 in contact with the ring portion 12, a flange portion 70 protruding laterally is provided around the pair of side surfaces 46a, the outer surface 46b, and the operation window portion 66. On the surface of the flange portion 70 on the ring portion 12 side, a semi-cylindrical portion 68 that is fitted into the locking hole 20 formed in the holding portion 18 of the ring portion 12 is provided. The semi-cylindrical portion 68 is notched on the opposite side of the operation window portion 66.

カバー４６をフック部３２に取り付けた時、操作用窓部６６には操作用突起６２がゆとりを有して嵌合されて外側へ突出する。連結部４６ｃは、ばね部６０の一部を外側から覆うように位置する。ばね部６０に内側から強い力が加えられた時、ばね部６０が連結部４６ｃに当接するため、先端部６０ａが端部３２ｂを乗り越えてばね部６０がフック部３２の外側に向けて変形することを制限する。また、連結部４６ｃとフック部３２の端部３２ｂの間の空間が挿通口４０となる。連結部４６ｃは、操作用窓部６６から露出するばね部６０と挿通口４０とを分断する。カバー４６の外側面４６ｂの端部は、フック部３２の段部５４に当接し、カバー４６がリング部１２と反対側に移動することを防ぐ。なお、フランジ部７０はリング部１２の係止孔２０の周囲に当接し、リング部１２側への移動することがない。 When the cover 46 is attached to the hook portion 32, the operation projection 62 is loosely fitted in the operation window portion 66 and protrudes outward. The connecting portion 46c is located so as to cover a part of the spring portion 60 from the outside. When a strong force is applied to the spring portion 60 from the inside, the spring portion 60 contacts the connecting portion 46c, so that the tip end portion 60a passes over the end portion 32b and the spring portion 60 is deformed toward the outside of the hook portion 32. Restrict things. The space between the connecting portion 46c and the end portion 32b of the hook portion 32 serves as the insertion opening 40. The connecting portion 46c divides the insertion portion 40 from the spring portion 60 exposed from the operation window portion 66. The end portion of the outer side surface 46b of the cover 46 contacts the step portion 54 of the hook portion 32 and prevents the cover 46 from moving to the side opposite to the ring portion 12. The flange portion 70 abuts around the locking hole 20 of the ring portion 12 and does not move to the ring portion 12 side.

次に、この実施形態の連結具５０の組立方法について説明する。フック部３２は、樹脂で一体に成形した工程で端部３２ｂの外側に位置しているばね部６０を、弾性変形させてフック部３２の端部３２ｂの側方から回して内側に入れる。この時、フック部３２の端部３２ｂの差込突起３３が、ばね部６０の透孔６５に差し込まれ、位置決めされる。先端部６０ａがフック部３２の端部３２ｂに当接し、内側から当たる方向に付勢力が働く。ばね部６０の先端部６０ａは、フック部３２の端部３２ｂの切欠部３４の内側に嵌合されてフック部３２の内側面に連続する。 Next, a method of assembling the connector 50 of this embodiment will be described. The hook portion 32 elastically deforms the spring portion 60, which is located outside the end portion 32b in the step of integrally molding the resin, and turns the spring portion 60 from the side of the end portion 32b of the hook portion 32 into the inside. At this time, the insertion protrusion 33 of the end portion 32b of the hook portion 32 is inserted into the through hole 65 of the spring portion 60 and positioned. The tip portion 60a comes into contact with the end portion 32b of the hook portion 32, and a biasing force acts in a direction of hitting from the inside. The tip portion 60a of the spring portion 60 is fitted inside the cutout portion 34 of the end portion 32b of the hook portion 32 and is continuous with the inner surface of the hook portion 32.

次に、フック部３２の軸部５２にカバー４６を、軸部５２の先端からフランジ部２６を通過させ、カバー４６の端部がフック部３２の段部５４に当接し、それ以上行かないように係止される。次に、リング部１２の係止孔２０に、フック部３２のフランジ部２６をベルト掛け１６の反対側から強い力で押し込む。係止孔２０よりもフランジ部２６の方が大きいため通過しないが、一定以上の力を加えるとリング部１２の保持部１８が弾性変形してスリット２２が広がり、係止孔２０の内径が広がり、通過可能となる。フランジ部２６が通過した後は弾性変形が戻り、フランジ部２６が係止されて抜け落ちず、リング部１２とフック部３２が、カバー４６を挟んだ状態で取り付けられる。 Next, the cover 46 is passed through the shaft portion 52 of the hook portion 32, and the flange portion 26 is passed from the tip of the shaft portion 52 so that the end portion of the cover 46 abuts the step portion 54 of the hook portion 32 and does not go any further. Locked in. Next, the flange portion 26 of the hook portion 32 is pushed into the locking hole 20 of the ring portion 12 from the opposite side of the belt hook 16 with a strong force. Since the flange portion 26 is larger than the locking hole 20, it does not pass, but when a certain force or more is applied, the holding portion 18 of the ring portion 12 elastically deforms and the slit 22 expands, and the inner diameter of the locking hole 20 expands. , Will be able to pass. After the flange portion 26 passes, the elastic deformation returns, the flange portion 26 is locked and does not fall off, and the ring portion 12 and the hook portion 32 are attached with the cover 46 sandwiched therebetween.

次に、リング部１２に、ベルトや肩紐等の幅広の長尺部材を取り付ける。フック部３２には、他の被掛止体を取り付ける。まず、カバー４６の操作用窓部６６から突出している操作用突起６２を内側に向かって押す。するとばね部６０が弾性変形し、ばね部６０の先端部６０ａが、フック部３２の端部３２ｂから離れて、挿通口４０が開放される。開放した挿通口４０から、フック部３２に被掛止体を通し、押す力を解除して、ばね部６０の弾性変形を復元して挿通口４０を閉鎖する。ばね部６０の先端部６０ａの透孔６５に、フック部３２の端部３２ｂの差込突起３３が差し込まれ、互いに確実に連結され挿通口４０が閉鎖される。ばね部６０はカバー４６の内側にわずかなゆとりを有して嵌合されているため、ばね部６０が弾性変形する際にずれることがなく、確実にフック部３２の端部３２ｂに再び当接して、端部３２ｂの差込突起３３がばね部６０の透孔６５に差し込まれて閉鎖される。ばね部６０の先端部６０ａに、フック部３２の端部３２ｂの側方へずれるような力が加えられても、カバー４６の側面４６ａに当接するため、ずれる方向への弾性変形を防ぎばね部６０が外れることがない。不用意に挿通口４０が開放されることがない。被掛止体が不要となった時は、同じ操作で外す。 Next, a wide long member such as a belt or a shoulder strap is attached to the ring portion 12. Another hooked body is attached to the hook portion 32. First, the operation protrusion 62 protruding from the operation window portion 66 of the cover 46 is pushed inward. Then, the spring portion 60 is elastically deformed, the tip portion 60a of the spring portion 60 is separated from the end portion 32b of the hook portion 32, and the insertion opening 40 is opened. The hooked body is passed through the hooked portion 32 through the opened insertion opening 40, the pushing force is released, the elastic deformation of the spring portion 60 is restored, and the insertion opening 40 is closed. The insertion protrusions 33 of the end portions 32b of the hook portions 32 are inserted into the through holes 65 of the tip end portion 60a of the spring portion 60, and are securely connected to each other to close the insertion opening 40. Since the spring portion 60 is fitted inside the cover 46 with a slight clearance, the spring portion 60 does not shift when elastically deformed, and surely comes into contact with the end portion 32b of the hook portion 32 again. Then, the insertion protrusion 33 of the end portion 32b is inserted into the through hole 65 of the spring portion 60 and closed. Even if a force is applied to the tip portion 60a of the spring portion 60 such that the end portion 32b of the hook portion 32 is laterally displaced, the spring portion 60 comes into contact with the side surface 46a of the cover 46, and thus elastic deformation in the displacement direction is prevented. 60 does not come off. The insertion opening 40 will not be opened carelessly. When the hooked object is no longer needed, remove it with the same operation.

この実施形態の連結具５０によれば、上記実施形態と同様の効果を有するものである。操作用突起６２が、カバー４６の操作用窓部６６から突出しているため、押しやすく、より操作が簡単なものである。また、ばね部６０から操作用突起６２を突出させることにより、ばね部６０を薄くすることができ、弾性変形を容易にすることができる。さらに、ばね部６０の先端部６０ａの透孔６５に、フック部３２の端部３２ｂの差込突起３３が差し込まれて係止されるため、より確実に挿通口４０が閉鎖される。 According to the connector 50 of this embodiment, the same effects as those of the above-described embodiment are obtained. Since the operation protrusion 62 projects from the operation window portion 66 of the cover 46, it is easy to push and the operation is easier. Further, by projecting the operation projection 62 from the spring portion 60, the spring portion 60 can be thinned and elastic deformation can be facilitated. Furthermore, since the insertion protrusion 33 of the end 32b of the hook portion 32 is inserted and locked in the through hole 65 of the tip portion 60a of the spring portion 60, the insertion opening 40 is closed more reliably.

次にこの発明の第三実施形態について図９〜図１１に基づいて説明する。なお、ここで、上記実施から形態と同様の部材は同様の符号を付して説明を省略する。この実施形態の連結具７２は、リング部１２とフック部３２が合成樹脂で一体に成形されて本体１４となっている。リング部１２には、ベルトや紐等を巻き回すベルト掛け１６と、ベルト掛け１６の両端を保持する一対の保持部１８が一体に設けられ、一対の保持部１８はベルト掛け１６に対して平行な側面を有する板部７６に連続して設けられている。一対の保持部１８は、板部７６の一方の側縁部７６ａの両端部に連結されている。 Next, a third embodiment of the present invention will be described with reference to FIGS.

板部７６の厚みよりもフック部３２のあつみが大きく、板部７６の側縁部７６ｂには、フック部３２との境界部分に段部７８が設けられている。板部７６の側縁部７６ｂは、挿通口４０に対向する部分が切り欠かれて短くなり、側縁部７６ａと側縁部７６ｂを結ぶ側縁部７６ｃは、側縁部７６ａから離れるにつれて、側縁部７６ｂのフック部３２が連結されている端部に近づくように傾斜している。 The thickness of the hook portion 32 is larger than the thickness of the hook portion 32, and the side edge portion 76 b of the hook portion 32 is provided with a step 78 at the boundary with the hook portion 32. The side edge portion 76b of the plate portion 76 is shortened by cutting away the portion facing the insertion opening 40, and the side edge portion 76c connecting the side edge portion 76a and the side edge portion 76b becomes farther away from the side edge portion 76a. The side edge portion 76b is inclined so as to approach the end portion to which the hook portion 32 is connected.

フック部３２の挿通口４０に対向する位置には、ばね部８０が設けられている。ばね部８０は、側縁部７６ｃのベルト掛け１６に近い位置に設けられている棒状部材であり、側縁部７６ｃに沿って、ベルト掛け１６から離れるにつれて少し間隔を大きくしながら延出し、フック部３２の端部３２ｂの内側面に達している。ばね部８０は、長手方向に交差する断面形状は矩形であり、フック部３２と連続して環状となる内側面と外側面の間の幅が薄いものであり、全体が弾性変形しやすい形状となる。ばね部８０の、板部７６の側縁部７６ｃの途中に対向する部分には、操作用突起８２が設けられている。操作用突起８２は、ばね部８０の板部７６と反対側の側面から外側に突出し、突出方向の途中で折り曲げられてベルト掛け１６の方へ延出している。ばね部８０の先端部８０ａには、フック部３２の端部３２ｂに形成された差込突起３３が差し込まれる透孔６５が設けられている。 A spring portion 80 is provided at a position of the hook portion 32 facing the insertion opening 40. The spring portion 80 is a bar-shaped member provided at a position of the side edge portion 76c close to the belt hook 16 and extends along the side edge portion 76c while slightly increasing the distance from the belt hook 16. The inner surface of the end 32b of the portion 32 is reached. The spring portion 80 has a rectangular cross-sectional shape that intersects in the longitudinal direction, has a narrow width between the inner surface and the outer surface that is continuous with the hook portion 32, and has a shape that is easily elastically deformed as a whole. Become. An operation protrusion 82 is provided at a portion of the spring portion 80 that faces the side edge portion 76c of the plate portion 76 in the middle thereof. The operation protrusion 82 protrudes outward from the side surface of the spring portion 80 opposite to the plate portion 76, is bent in the middle of the protrusion direction, and extends toward the belt hook 16. A through hole 65 into which the insertion protrusion 33 formed at the end 32b of the hook portion 32 is inserted is provided at the tip end portion 80a of the spring portion 80.

ばね部８０は、本体１４が樹脂で一体に形成された工程では、フック部３２の外側に位置し、先端部８０ａに近づくほどフック部３２の端部３２ｂから離れる方向に傾斜して延出している。この後、連結具７２を組み立てる工程で、ばね部８０を弾性変形させてフック部３２の端部３２ｂの内側に入れる。先端部８０ａの透孔６５には、端部３２ｂの差込突起３３が差し込まれる。この状態で、ばね部８０の操作用突起８２を外側から押すと、ばね部８０全体が弾性変形して先端部８０ａがフック部３２の端部３２ｂから離れ、挿通口４０が開放される。押す力を解除すると、ばね部８０は弾性力で復元してフック部３２の端部３２ｂに当接し、挿通口４０が閉鎖される。 In the step of integrally forming the main body 14 with resin, the spring portion 80 is located outside the hook portion 32, and extends so as to incline in a direction away from the end portion 32b of the hook portion 32 as it approaches the tip portion 80a. There is. After that, in the step of assembling the connector 72, the spring portion 80 is elastically deformed and put inside the end portion 32b of the hook portion 32. The insertion protrusion 33 of the end portion 32b is inserted into the through hole 65 of the tip portion 80a. When the operating projection 82 of the spring portion 80 is pushed from the outside in this state, the entire spring portion 80 is elastically deformed, the tip portion 80a is separated from the end portion 32b of the hook portion 32, and the insertion opening 40 is opened. When the pushing force is released, the spring portion 80 is restored by the elastic force and comes into contact with the end portion 32b of the hook portion 32, and the insertion opening 40 is closed.

板部７６には、ばね部８０の一部を覆う筒状のカバー８４が設けられている。カバー８４は、板部７６とばね部８０の両側を覆う互いに平行な一対の側面８４ａと、一対の側面８４ａの側縁部同士を連結しフック部３２の端部３２ａの近傍を覆う外側面８４ｂと、一対の側面８４ａの、外側面８４ｂと反対側の側縁部同士を連結する連結部８４ｃで形成された筒状体である。一対の側面８４ａは、ばね部８０が一対の側面８４ａの間を弾性変形する際に、ばね部８０が挿通口４０を開閉する弾性変形の方向に沿ってその揺動方向をガイドする。カバー８４の、本体１４に取り付けた時にベルト掛け１６側となる端部は、側面８４ａは、板部７６の側縁部７６ｂに沿う平面状であり、外側面８４ｂ、連結部８４ｃは、側面８４ａの端部よりも保持部１８の基端部を覆うように少し外側に達している。カバー８４の、本体１４に取り付けた時にフック部３２側となる端部は、側縁部７６ｂに沿って段部７８に対向する形状になっている。連結部８４ｃには、操作用突起８２に対向する位置で上下に分断されて、操作用窓部８６が設けられている。操作用窓部８６からは、操作用突起８２が外側に突出する。連結部８４ｃは、ばね部８０の一部を外側から覆うように位置する。ばね部８０に内側から強い力が加えられた時、ばね部８０が連結部８４ｃに当接するため、先端部８０ａが端部３２ｂを乗り越えてばね部８０がフック部３２の外側に向けて変形することを制限する。また、連結部８４ｃとフック部３２の端部３２ｂの間の空間が挿通口４０となる。フック部３２側に位置する連結部８４ｃは、操作用窓部８６から露出するばね部８０と挿通口４０とを分断する。 The plate portion 76 is provided with a cylindrical cover 84 that covers a part of the spring portion 80. The cover 84 connects a pair of parallel side surfaces 84a that covers both sides of the plate portion 76 and the spring portion 80, and an outer surface 84b that connects the side edge portions of the pair of side surfaces 84a and covers the vicinity of the end portion 32a of the hook portion 32. And a cylindrical body formed by a connecting portion 84c that connects side edges of the pair of side surfaces 84a opposite to the outer side surface 84b. When the spring portion 80 elastically deforms between the pair of side surfaces 84a, the pair of side surfaces 84a guides the swinging direction along the elastic deformation direction in which the spring portion 80 opens and closes the insertion port 40. An end portion of the cover 84 which is on the belt hanging 16 side when attached to the main body 14 has a side surface 84a which is a flat surface along the side edge portion 76b of the plate portion 76, and an outer side surface 84b and a connecting portion 84c which are side surfaces 84a. To a little outside so as to cover the base end portion of the holding portion 18 rather than the end portion. An end portion of the cover 84, which is on the hook portion 32 side when attached to the main body 14, has a shape facing the step portion 78 along the side edge portion 76b. The connecting portion 84c is provided with an operation window portion 86 which is vertically divided at a position facing the operation protrusion 82. The operation projection 82 projects outward from the operation window portion 86. The connecting portion 84c is located so as to cover a part of the spring portion 80 from the outside. When a strong force is applied to the spring portion 80 from the inside, the spring portion 80 contacts the connecting portion 84c, so that the tip end portion 80a gets over the end portion 32b and the spring portion 80 is deformed toward the outside of the hook portion 32. Restrict things. Further, the space between the connecting portion 84c and the end portion 32b of the hook portion 32 serves as the insertion port 40. The connecting portion 84c located on the hook portion 32 side separates the spring portion 80 exposed from the operation window portion 86 from the insertion opening 40.

次に、この実施形態の連結具７２の組立方法について説明する。本体１４は、樹脂で一体に成形した工程で端部３２ｂの外側に位置しているばね部８０を、弾性変形させてフック部３２の端部３２ｂの側方から回して内側に入れる。この時、フック部３２の端部３２ｂの差込突起３３が、ばね部８０の透孔６５に差し込まれ、位置決めされる。先端部８０ａがフック部３２の端部３２ｂに当接し、内側から当たる方向に付勢力が働く。ばね部８０の先端部８０ａは、フック部３２の端部３２ｂの切欠部３４の内側に嵌合されてフック部３２の内側面に連続する。次に、本体１４の板部７６にカバー８４を、ベルト掛け１６側からかぶせて取り付け、カバー８４の端部が本体１４の段部７８に当接し、それ以上行かないように係止される。また、カバー８４の内周面に形成された図示しない係止部が本体１４に係止する。この状態で、ベルト掛け１６は、カバー８４の反対側の端部から外側に突出する。操作用突起８２は、カバー８４の操作用窓部８６から外側に突出する。 Next, a method of assembling the connector 72 of this embodiment will be described. The main body 14 elastically deforms the spring portion 80, which is located outside the end portion 32b in the step of integrally molding with resin, and rotates it from the side of the end portion 32b of the hook portion 32 to put it inside. At this time, the insertion protrusion 33 of the end portion 32b of the hook portion 32 is inserted into the through hole 65 of the spring portion 80 and positioned. The tip portion 80a comes into contact with the end portion 32b of the hook portion 32, and a biasing force acts in a direction of hitting from the inside. The tip portion 80a of the spring portion 80 is fitted inside the cutout portion 34 of the end portion 32b of the hook portion 32 and is continuous with the inner surface of the hook portion 32. Next, the cover 84 is attached to the plate portion 76 of the main body 14 by covering it from the side of the belt 16 and the end portion of the cover 84 abuts the stepped portion 78 of the main body 14 and is locked so as not to go any further. Further, a locking portion (not shown) formed on the inner peripheral surface of the cover 84 locks with the main body 14. In this state, the belt hook 16 projects outward from the opposite end of the cover 84. The operation protrusion 82 projects outward from the operation window portion 86 of the cover 84.

次に、リング部１２に、ベルトや肩紐等の幅広の長尺部材を取り付ける。フック部３２には、他の被掛止体を取り付ける。まず、カバー８４の操作用窓部８６から突出している操作用突起８２を内側に向かって押す。するとばね部８０が弾性変形し、ばね部８０の先端部８０ａが、フック部３２の端部３２ｂから離れて、挿通口４０が開放される。開放した挿通口４０から、フック部３２に被掛止体を通し、押す力を解除して、ばね部８０の弾性変形を復元して挿通口４０を閉鎖する。ばね部８０の先端部８０ａの透孔６５に、フック部３２の端部３２ｂの差込突起３３が差し込まれ、互いに確実に連結され挿通口４０が閉鎖される。ばね部８０はカバー８４の内側にわずかなゆとりを有して嵌合されているため、ばね部８０が弾性変形する際にずれることがなく、確実にフック部３２の端部３２ｂに再び当接して、端部３２ｂの差込突起３３がばね部８０の透孔６５に差し込まれて閉鎖される。ばね部８０の先端部８０ａに、フック部３２の端部３２ｂの側方へずれるような力が加えられても、カバー８４の側面８４ａに当接するため、ずれる方向への弾性変形を防ぎばね部８０が外れることがない。不用意に挿通口４０が開放されることがない。被掛止体が不要となった時は、同じ操作で外す。 Next, a wide long member such as a belt or a shoulder strap is attached to the ring portion 12. Another hooked body is attached to the hook portion 32. First, the operation protrusion 82 protruding from the operation window portion 86 of the cover 84 is pushed inward. Then, the spring portion 80 is elastically deformed, the tip portion 80a of the spring portion 80 is separated from the end portion 32b of the hook portion 32, and the insertion opening 40 is opened. The hooked body is passed through the hooked portion 32 through the opened insertion opening 40, the pushing force is released, the elastic deformation of the spring portion 80 is restored, and the insertion opening 40 is closed. The insertion protrusions 33 of the end portions 32b of the hook portions 32 are inserted into the through holes 65 of the tip end portion 80a of the spring portion 80, and are securely connected to each other to close the insertion opening 40. Since the spring portion 80 is fitted inside the cover 84 with a slight allowance, the spring portion 80 does not shift when elastically deformed, and surely contacts the end portion 32b of the hook portion 32 again. Then, the insertion protrusion 33 of the end portion 32b is inserted into the through hole 65 of the spring portion 80 and closed. Even if a force is applied to the tip end portion 80a of the spring portion 80 such that the end portion 32b of the hook portion 32 is laterally displaced, the spring portion 80 comes into contact with the side surface 84a of the cover 84, and thus elastic deformation in the displacement direction is prevented. 80 never comes off. The insertion opening 40 will not be opened carelessly. When the hooked object is no longer needed, remove it with the same operation.

この実施形態の連結具７２によれば、上記実施形態と同様の効果を有するものである。本体１４はベルト掛け１６とフック部３２が一体に設けられ、強い力で長尺部材とその他の物品を連結することができる。フック部３２はコの字形に形成されて板部７６の側縁部７６ｂに沿って一方向に長い取り付け空間を形成するため、フック部３２にも幅広の長尺部材を取り付けることができる。 According to the connector 72 of this embodiment, the same effects as those of the above-described embodiment are obtained. The main body 14 is integrally provided with the belt hook 16 and the hook portion 32, and can connect the long member and other articles with a strong force. Since the hook portion 32 is formed in a U shape and forms a long attachment space in one direction along the side edge portion 76b of the plate portion 76, a wide long member can be attached to the hook portion 32 as well.

なお、この実施形態の連結具７２は、本体１４の操作用突起８２と、カバー８４の操作用窓部８６を、異なる形状にしても良い。例えば、図１２、図１３に示す連結具７２は、操作用突起８２がばね部８０の板部７６と反対側の側面から外側に突出し、突出方向の途中で折り曲げられてベルト掛け１６の方へ延出し、先端部分は突出方向に厚く形成されている。カバー８４の操作用窓部８６は、連結部８４ｃを分断することなく、連結部８４ｃの側面に矩形の操作用窓部８６が設けられている。操作用突起８２が厚く形成されているため、連結部８４ｃを分断して操作用窓部８６をくぼむように形成しなくても、十分な長さで操作用窓部８６から操作用突起８２が突出することができる。これにより、カバー８４の操作用窓部８６周辺の強度を高めることができる。 In the connector 72 of this embodiment, the operation protrusion 82 of the main body 14 and the operation window portion 86 of the cover 84 may have different shapes. For example, in the connector 72 shown in FIGS. 12 and 13, the operation projection 82 projects outward from the side surface of the spring section 80 opposite to the plate section 76, and is bent in the middle of the projecting direction toward the belt hook 16. The extending and tip portion is formed thick in the protruding direction. The operation window portion 86 of the cover 84 is provided with a rectangular operation window portion 86 on the side surface of the connecting portion 84c without dividing the connecting portion 84c. Since the operation projection 82 is formed thick, the operation projection 82 is sufficiently long from the operation window portion 86 without having to divide the connecting portion 84c to form the operation window portion 86 in a depressed manner. Can be projected. As a result, the strength around the operation window portion 86 of the cover 84 can be increased.

なお、この実施形態の連結具７２は、図１４、図１５に示すように、カバー８４の外側面８４ｂに、一対の側面８４ａの側面に対して平行なスリット８５が設けられて２分割されてもよい。側面８４ａが分割されることによりカバー８４は弾性変形しやすくなり、本体１４への取り付けが容易となり、生産効率を上げることができる。 As shown in FIGS. 14 and 15, the connector 72 of this embodiment is divided into two parts by providing a slit 85 parallel to the side surfaces of the pair of side surfaces 84a on the outer side surface 84b of the cover 84. Good. Since the side surface 84a is divided, the cover 84 is easily elastically deformed, is easily attached to the main body 14, and the production efficiency can be improved.

さらに、この実施形態の連結具７２は、図１６、図１７に示すように、カバー８４に、本体１４のベルト掛け１６を覆うバー覆い部８８が一体に設けられてもよい。バー覆い部８８は、ベルト掛け１６を内側に嵌合する断面Ｕ字形の嵌合部であり、Ｕ字の開口部は側面８４ａに近い方向に開口している。バー覆い部８８は、ベルト掛け１６と保持部１８を覆うようにコの字形に折り曲げられ、両端部が外側面８４ｂと連結部８４ｃに、一体に連結されている。側面８４ａの内側面には、本体１４に係止される係止部９０が設けられている。 Further, in the connector 72 of this embodiment, as shown in FIGS. 16 and 17, the cover 84 may be integrally provided with the bar cover portion 88 that covers the belt hook 16 of the main body 14. The bar cover portion 88 is a fitting portion having a U-shaped cross section that fits the belt hook 16 inside, and the U-shaped opening portion opens in a direction close to the side surface 84a. The bar cover portion 88 is bent in a U shape so as to cover the belt hook 16 and the holding portion 18, and both ends thereof are integrally connected to the outer side surface 84b and the connecting portion 84c. A locking portion 90 that is locked to the main body 14 is provided on the inner side surface of the side surface 84a.

ベルト掛け１６にカバー８４のバー覆い部８８が重ねられて取り付けられることにより、ベルト掛け１６の強度が高くなる。また連結具７２の表面に本体１４とカバー８４の境界線である段差が少なくなり、外観が良好で、汚れが付着しない。またカバー８４と本体１４の取り付け強度も高い。 By attaching the bar cover portion 88 of the cover 84 to the belt hook 16 so as to overlap with each other, the strength of the belt hook 16 is increased. In addition, the step which is the boundary line between the main body 14 and the cover 84 is reduced on the surface of the connector 72, the appearance is good, and dirt does not adhere. Also, the attachment strength between the cover 84 and the main body 14 is high.

なお、この発明の連結具は、上記各実施の形態に限定されるものではなく、フック部とカバー、ばね部の形状は適宜変更可能であり、カバーがばね部に確実に取り付けられるものであれば良い。カバーは筒状でなくてもよく、確実にばね部に取り付けられるものであればよく、コの字形等、側面の一部が切り欠かれたものでもよい。フック部に取り付ける被掛止物は、カメラ、ホイッスル、カバン、ケース等、色々なものに使用することができる。各部材の材料や色、表面処理、透明度などは自由に変更可能であり、デザインや必要な機能に合わせて適宜変更可能である。カバーを、本体と異なる色にしたり、透明にしたり、メッキ処理をしたり、加飾することで連結具のイメージを簡単に変えることができる。 The connector of the present invention is not limited to the above-mentioned respective embodiments, and the shapes of the hook portion, the cover, and the spring portion can be changed as appropriate, and the cover can be securely attached to the spring portion. Good. The cover does not have to be cylindrical, and may be anything that can be reliably attached to the spring portion, and may be a U-shaped cover with a part of the side surface cut away. The hooked object attached to the hook can be used for various things such as a camera, a whistle, a bag, and a case. The material, color, surface treatment, transparency, etc. of each member can be freely changed, and can be appropriately changed according to the design and the required function. The image of the connector can be easily changed by making the cover different in color from the main body, transparent, plated, or decorated.
