  • the abutting portion 324 abuts against the outer surface 221A of the coupler 1, thereby restricting the opening-closing portion 3 from moving in the A1 direction beyond the opening-open position P2.
  • the distance between the second hooking portion 221 and the abutting portion 324 is wide enough to form a gap 325 between the second hooking portion 221 and the abutting portion 324.

  • the elastically deforming portion 4 is also located a certain distance away from the extension portion 23, ensuring space for elastic deformation of the elastically deforming portion 4.
  • This elastically deforming portion 4 constantly biases the opening/closing portion 3 in the A2 direction even when the opening is in the closed position P1, and its elastic deformation allows the opening/closing portion 3 to swing slightly in the B direction.

  • Figs. 2 to 4 show the connector 1 in a closed state in the assembled state, with the opening/closing portion 3 positioned at the opening closing position P1.
  • the opening 11 in the connector 1 is opened and closed as follows. (Opening operation) When the opening-closing unit 3 is positioned at the opening closing position P1 and in a closed state (fully closed state), the hook-shaped engaging units 213, 313 are disengaged from the connector 1. Specifically, the hook-shaped engaging units 213, 313 are disengaged by slightly bending the main body 2 toward the accommodation space 10 or by moving the opening-closing unit 3, which is held by the elastic deformation unit 4 so that it can swing slightly in direction B, closer to one end 21 of the main body 2. This allows the opening-closing unit 3 to move open in direction A1. Next, the opening-closing unit 3 is operated to move open in direction A1 against the bias of the elastic deformation unit 4, thereby opening the opening 11.
  • the opening/closing unit 3 is in an open state (fully open state) when positioned at the opening-open position P2 without abutting the inner portion (inner periphery) of the main body 2.
  • This open state allows a portion of an article, such as a string, to be connected through the opening 11 into the storage space 10, allowing the connector 1 to be connected to an article, to connect articles to each other, or to connect parts of articles to each other.
  • the opening/closing unit 3 can be moved in the A direction between the opening-closing position P1 and the opening-open position P2. (Closing operation) When the opening operation of the opening-closing part 3 of the connector 1 in the open state is stopped, the opening-closing part 3 moves in the closing direction A2 due to the bias of the elastic deformation part 4.
  • the first hooking part 211 of the main body part 2 is placed in the groove part 315 at the tip end 31 of the opening-closing part 3, and the abutment plate part 312 of the first hooked part 311 is brought into contact with or able to contact the inner surface 211A of the first hooking part 211, and the hook-shaped engaging part 313 is engaged with the hook-shaped engaging part 213, thereby placing the opening-closing part 3 in the opening-closing position P1 and entering the closed state.

  • the first hooked portion 311 is hooked to the first hooking portion 211
  • the second hooked portion 323 is hooked to the second hooking portion 221 inserted into the through-hole 322. Therefore, compared to when the base end of the opening/closing portion is pivotally supported on the main body, for example, the second hooking portion 221 can be inserted deeply into the insertion connecting portion 321, and the second hooked portion 323 having the above-described configuration can be hooked to the second hooking portion 221, thereby improving the strength of the connector 1 against forces in the A2 direction and twisting forces.
  • the connector 1 is in the closed state when the first hooked portion 311 is hooked on the first latching portion 211 and the second hooked portion 323 is hooked on the second latching portion 221 in the opening-closing position P1, but the first hooked portion 311 and the second hooked portion 323 do not necessarily have to abut against each other as long as they are in the hooked state.
  • the outer diameter contour of the elastic deformation portion 4 is arranged along the outer diameter contour line (virtual line) of the main body portion 2, and cooperates with the main body portion 2 and the opening/closing portion 3 to form a circular connecting device 1.
  • the opening/closing section 3 moves open in the A1 direction, causing the abutment plate section 312 to move away from the inner surface 211A of the first hooking section 211, disengaging the first hooked section 311 from the first hooking section 211, and the hooked protrusion 323A to come off the hooking protrusion 223, disengaging the second hooked section 323 from the second hooking section 221.

Description

連結具Connector

　本発明は、物品に連結されたり、別々の物品同士や部位同士を互いに連結したりするカラビナ、なす環などの連結具に関する。 The present invention relates to connectors such as carabiners and rings that are used to connect items or to connect separate items or parts to each other.

　従来、別々の物品や部位を互いに連結するものとして、収容空間およびフック部が形成されたベース部と、ベース部にバネ部を介して一体に連続する開閉体とを備える連結具が知られている（特許文献１参照）。ベース部には軸穴が形成されており、開閉体の基端部には軸穴に軸支される軸部が形成されている。この連結具では、軸部を中心とする開閉体の回動によって、ベース部の収容空間に連通する開口を開閉可能としている。 Conventionally, a connector for connecting separate items or parts to each other has been known, which includes a base portion in which a storage space and a hook portion are formed, and an opening/closing body that is connected to the base portion via a spring portion (see Patent Document 1). A shaft hole is formed in the base portion, and a shaft portion that is supported by the shaft hole is formed at the base end of the opening/closing body. With this connector, the opening that communicates with the storage space in the base portion can be opened and closed by rotating the opening/closing body around the shaft portion.

国際公開第２０２４／０４７７９６号International Publication No. 2024/047796

　ところで、特許文献１に記載の連結具では、開閉体の基端部は軸部がベース部の軸穴に軸支されるだけであるので、連結具の外側に開閉体を外す方向や捻り方向に対する強度の向上を図り難い。また、開閉体の基端部は軸部がベース部の軸穴に軸支されているため、その部分を基点にして開閉体が回動するので、バネ部の一部の弾性力のみを利用して開閉体を開閉することとなり、バネ部の一部にのみ集中的に負荷がかかってしまって、この観点からも連結具の強度の向上を図り難い。 In the connector described in Patent Document 1, the base end of the opening/closing body has an axle that is simply supported in an axle hole in the base, making it difficult to improve strength in the direction of removing the opening/closing body from the connector or in the twisting direction. Furthermore, because the base end of the opening/closing body has an axle that is supported in an axle hole in the base, the opening/closing body rotates around that point, so the opening/closing body is opened and closed using only the elastic force of part of the spring, and the load is concentrated on only part of the spring, making it difficult to improve the strength of the connector from this perspective as well.

　本発明の目的は、強度の向上を図り得る連結具を提供することにある。 The object of the present invention is to provide a connector that can improve strength.

［本実施形態の構成］
　以下、本発明の実施形態を図面に基づいて説明する。
　図１から図３において、本実施形態に係る連結具１は、物品に連結されたり、別々の物品同士や部位同士を互いに連結したりする丸型の樹脂製カラビナとして構成されている。連結具１は、被連結体（図示省略）としての物品の紐などの部位が通される収容空間１０を形成し且つ収容空間１０に連通する開口１１を一端部２１および他端部２２で区画する本体部２と、開口１１を開閉する開閉部３と、開閉部３が開閉移動可能となるように本体部２および開閉部３を接続する弾性変形部４とを有しており、樹脂製材料によって一体的に１部材として形成されている。開閉部３は、その開閉移動によって、開口１１を閉鎖する開口閉鎖位置Ｐ１(図４参照)と、開口１１を開放する開口開放位置Ｐ２（図５参照）とに配置可能である。なお、本実施形態では、開口閉鎖位置Ｐ１は、開閉部３が連結具１の周方向に沿った位置であり、開口開放位置Ｐ２は、開閉部３が開口閉鎖位置Ｐ１よりも収容空間１０内に入り込んだ位置である。
　以下の説明において、連結具１の左右方向をＸ軸方向とし、連結具１の前後方向（幅方向）をＹ軸方向とし、連結具１の上下方向をＺ軸方向とする。Ｘ，Ｙ，Ｚ軸方向は互いに直交する。また、開閉方向はＡ方向とし、開放方向はＡ１方向とし、閉鎖方向はＡ２方向とする。閉鎖状態における開閉部３の先端部３１と本体部２の一端部２１との対向方向をＢ方向とする（本実施形態では連結具１の周方向でもある）。なお、上記各方向は本実施形態の説明において便宜的に設定した方向であり、実際の使用状態における連結具１では、適宜各向きに配置される。 [Configuration of this embodiment]
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
1 to 3, the connector 1 according to this embodiment is configured as a round, resin-made carabiner that can be connected to an article or can connect separate articles or parts to each other. The connector 1 includes a main body 2 that defines a storage space 10 through which a string or other part of an article (not shown) is passed and that defines an opening 11 that communicates with the storage space 10 at one end 21 and the other end 22; an opening/closing section 3 that opens and closes the opening 11; and an elastically deformable section 4 that connects the main body 2 and the opening/closing section 3 so that the opening/closing section 3 can be moved between an opening-closing position P1 (see FIG. 4) that closes the opening 11 and an opening-opening position P2 (see FIG. 5) that opens the opening 11 by its opening/closing movement. In this embodiment, the opening closing position P1 is a position where the opening/closing portion 3 is along the circumferential direction of the connecting device 1, and the opening opening position P2 is a position where the opening/closing portion 3 is further inside the storage space 10 than the opening closing position P1.
In the following description, the left-right direction of the connector 1 is referred to as the X-axis direction, the front-rear direction (width direction) of the connector 1 as the Y-axis direction, and the up-down direction of the connector 1 as the Z-axis direction. The X, Y, and Z-axis directions are perpendicular to one another. The opening and closing direction is referred to as the A-axis direction, the opening direction as the A1-axis direction, and the closing direction as the A2-axis direction. The opposing direction between the tip 31 of the opening/closing part 3 and one end 21 of the main body part 2 in the closed state is referred to as the B-axis direction (also the circumferential direction of the connector 1 in this embodiment). Note that the above directions are set for convenience in the description of this embodiment, and the connector 1 in actual use will be oriented in each of these directions as appropriate.

　本体部２は、被連結体が掛けられるようにフック状、本実施形態ではＣ字状に屈曲して形成されており、その内周面で収容空間１０を区画している。本実施形態では、本体部２の円弧中心よりもＸ軸方向における一方側の位置を収容空間１０の奥側とし、本体部２の円弧中心よりもＸ軸方向における他方側の位置を手前側とする。Ｘ軸方向における他方側の位置には、開口１１が配置されている。 The main body 2 is bent in a hook shape, or in this embodiment, a C-shape, so that a connected object can be hung on it, and its inner peripheral surface defines the storage space 10. In this embodiment, the position on one side of the arc center of the main body 2 in the X-axis direction is the back side of the storage space 10, and the position on the other side of the arc center of the main body 2 in the X-axis direction is the front side. An opening 11 is located at the position on the other side in the X-axis direction.

　本体部２の一端部２１および他端部２２は、開口１１を間にして連結具１の周方向に対向して配置されている。また、本体部２には、弾性変形部４との接続位置から開口１１側に向かって周方向に延設される延設部２３を有しており、他端部２２は当該延設部２３の先端部で構成されている。連結具１の径方向における延設部２３の寸法は、弾性変形部４の前記径方向における寸法よりも大きく且つ本体部２のうち前記延設部２３の除く部分の前記径方向における寸法よりも小さい。 One end 21 and the other end 22 of the main body 2 are arranged opposite each other in the circumferential direction of the connector 1, with the opening 11 between them. The main body 2 also has an extension 23 that extends circumferentially from the connection position with the elastically deforming portion 4 toward the opening 11, and the other end 22 is formed by the tip of the extension 23. The dimension of the extension 23 in the radial direction of the connector 1 is greater than the dimension of the elastically deforming portion 4 in the radial direction and smaller than the dimension of the portion of the main body 2 excluding the extension 23 in the radial direction.

　一端部２１には、Ａ２方向において開閉部３の後述する第一被掛止部３１１に対して解除可能に掛かり合う第一掛止部２１１が形成されている。第一掛止部２１１のＹ軸方向の幅寸法は、当該第一掛止部２１１に連続する部分よりも小さい寸法とされている。第一掛止部２１１は、Ａ２方向において第一被掛止部３１１に当接する内面２１１Ａを有しており、また、先端に鉤状の係合部２１３を有している。係合部２１３は、開閉部３の後述する鉤状の係合部３１３と解除可能に係合する。 A first hooking portion 211 is formed on one end portion 21, which releasably engages with a first hooked portion 311 (described later) of the opening/closing unit 3 in the A2 direction. The width dimension of the first hooking portion 211 in the Y-axis direction is smaller than the portion continuous with the first hooking portion 211. The first hooking portion 211 has an inner surface 211A that abuts against the first hooked portion 311 in the A2 direction, and also has a hook-shaped engaging portion 213 at its tip. The engaging portion 213 releasably engages with a hook-shaped engaging portion 313 (described later) of the opening/closing unit 3.

　他端部２２には、Ａ２方向において開閉部３の後述する第二被掛止部３２３に対して解除可能に掛かり合う第二掛止部２２１が形成されている。第二掛止部２２１のＹ軸方向の幅寸法は、当該第二掛止部２２１に連続する部分よりも小さい寸法とされている。第二掛止部２２１は図１、図４などに示すように鈎針形状とされており、第二掛止部２２１の基端部と連続する部分（延設部２３の長手方向における中間部分）には図１、図２などに示すように段部２２２がＹ軸方向に突出して形成されている。このため、延設部２３のＹ軸方向における寸法は、段部２２２の位置よりも基端側で大きく、段部２２２の位置よりも先端側で小さい。この段部２２２は、開口開放位置Ｐ２で開閉部３のうち後述する差込連結部３２１の差込側の部分に当接するように配置されている。第二掛止部２２１の先端部には、収容空間１０側である内側に向けて突出する係止突部２２３と、当該内側とは反対側である外側に向けて突出した突部２２４とが形成されている。第二掛止部２２１の外面２２１Ａのうち突部２２４に連続する部分には後述する当接部３２４の移動軌跡から外れるように内側に凹んだ凹部２２１Ｂが形成されており、このように凹部２２１Ｂを形成することで、開閉部３がＡ１方向に開放移動する際に、当接部３２４が外面２２１Ａに当接する位置を収容空間１０側に深く入り込んだ位置にすることができて、開閉部３の開閉移動領域を広げることができる。 The other end 22 is formed with a second hooking portion 221 that releasably engages with a second hooked portion 323 (described later) of the opening/closing unit 3 in the A2 direction. The width dimension of the second hooking portion 221 in the Y-axis direction is smaller than that of the portion continuous with the second hooking portion 221. The second hooking portion 221 is shaped like a hook, as shown in Figures 1 and 4, and a step 222 is formed protruding in the Y-axis direction at the portion continuous with the base end of the second hooking portion 221 (the middle portion in the longitudinal direction of the extension portion 23), as shown in Figures 1 and 2. Therefore, the dimension of the extension portion 23 in the Y-axis direction is larger on the base end side than the position of the step 222 and smaller on the tip end side than the position of the step 222. This step 222 is positioned so as to abut the insertion side portion of the opening/closing unit 3 of the plug-in connecting portion 321 (described later) at the opening open position P2. The tip of the second hooking portion 221 is formed with a locking protrusion 223 that protrudes inward, toward the storage space 10, and a protrusion 224 that protrudes outward, on the opposite side from the inward side. The outer surface 221A of the second hooking portion 221, adjacent to the protrusion 224, is formed with a recess 221B that is recessed inward so as to deviate from the movement trajectory of the abutting portion 324 (described below). By forming the recess 221B in this manner, when the opening/closing portion 3 moves to open in the A1 direction, the position where the abutting portion 324 abuts against the outer surface 221A can be positioned deeper toward the storage space 10, thereby expanding the opening/closing movement range of the opening/closing portion 3.

　開閉部３は、円弧状に形成されており、開口閉鎖位置Ｐ１に配置された状態で本体部２と協働して円環状の連結具１を構成する。開閉部３の先端部３１は、開口閉鎖位置Ｐ１に配置された状態で本体部２の一端部２１に対してＢ方向に対向して配置されており、開閉部３の基端部３２は、外周側寄りの部分で弾性変形部４に接続されている。 The opening/closing part 3 is formed in an arc shape, and when positioned in the opening-closing position P1, it cooperates with the main body part 2 to form the annular connector 1. When positioned in the opening-closing position P1, the tip part 31 of the opening/closing part 3 is positioned opposite one end part 21 of the main body part 2 in direction B, and the base part 32 of the opening/closing part 3 is connected to the elastic deformation part 4 at a portion closer to the outer periphery.

　先端部３１は、開口閉鎖位置Ｐ１で本体部２の一端部２１に対してＡ２方向に掛け止められ且つＡ１方向の移動（開放移動）において当該掛け止め状態が解除される第一被掛止部３１１を有している。
　第一被掛止部３１１は、先端部３１の内周側（内側）寄りの部分に形成され且つ開口閉鎖位置Ｐ１で第一掛止部２１１の内面２１１Ａに当接可能な当接板部３１２と、当接板部３１２の先端に連続する鉤状の係合部３１３とを有している。当接板部３１２は、その外面が内面２１１Ａに当接し、このように当接することで、第一被掛止部３１１は、第一掛止部２１１に対してＡ２方向に掛かり合った状態とされる。係合部３１３は、開口閉鎖位置Ｐ１で第一掛止部２１１の係合部２１３と解除可能に係合し、当該係合によって開口１１を閉鎖した閉鎖状態を安定させる。また、第一被掛止部３１１は、当接板部３１２に連続する一対の側板部３１４を有しており、当接板部３１２および一対の側板部３１４によって第一掛止部２１１が抜出可能に配置される溝部３１５が形成されている。 The tip portion 31 has a first latched portion 311 that is latched in the A2 direction to one end 21 of the main body portion 2 at the opening closing position P1 and that is released from the latched state when moved in the A1 direction (opening movement).
The first hooked portion 311 has an abutting plate portion 312 formed on a portion closer to the inner periphery (inner side) of the tip portion 31 and capable of abutting against the inner surface 211A of the first hooking portion 211 at the opening closing position P1, and a hook-shaped engaging portion 313 continuous with the tip of the abutting plate portion 312. The outer surface of the abutting plate portion 312 abuts against the inner surface 211A, and this abutment causes the first hooked portion 311 to be engaged with the first hooking portion 211 in the A2 direction. The engaging portion 313 releasably engages with the engaging portion 213 of the first hooking portion 211 at the opening closing position P1, and this engagement stabilizes the closed state in which the opening 11 is closed. In addition, the first hooking portion 311 has a pair of side plate portions 314 that are continuous with the abutment plate portion 312, and the abutment plate portion 312 and the pair of side plate portions 314 form a groove portion 315 in which the first hooking portion 211 is positioned so that it can be removed.

　基端部３２は、開閉部３のＡ方向の開閉移動を許容可能に本体部２の他端部２２が差し込まれる差込連結部３２１を有している。
　差込連結部３２１は、収容空間１０側である内側で開口し且つ開閉部３の開閉移動を許容可能に本体部２の他端部２２が配置される配置穴部３２０を有している。配置穴部３２０には、第二被掛止部３２３が配置されている。本実施形態では、配置穴部３２０は、収容空間１０側である内側から反対側である外側に貫通する貫通孔３２２で形成されており、貫通孔３２２のうち連結具１の内周側寄り部分には、開口閉鎖位置Ｐ１で本体部２の他端部２２に掛け止められるように当該貫通孔３２２を形成する内壁３２２Ａから突出した第二被掛止部３２３が形成されており、第二被掛止部３２３の先端には、収容空間１０側である内側から反対側である外側に突出した被係止突部３２３Ａが形成されている。また、差込連結部３２１の内壁３２２Ａのうち、第二被掛止部３２３との間に第二掛止部２２１が位置する部分は、開口開放位置Ｐ２で第二掛止部２２１の外面２２１Ａに当接する当接部３２４とされている。連結具１は、当接部３２４が外面２２１Ａに当接することで、開閉部３が開口開放位置Ｐ２よりもＡ１方向に開放移動されることを規制する。なお、第二掛止部２２１および当接部３２４の間の間隔は、第二掛止部２２１との間に隙間３２５が形成される程度に広い間隔とされており、隙間３２５が形成されることで、隙間３２５分の揺動が開閉部３に許容されている。これにより、開閉部３のＡ方向の開閉移動が円滑に行われるようになっている。
　この第二被掛止部３２３は、開口閉鎖位置Ｐ１で被係止突部３２３Ａが係止突部２２３に係止されることで、第二掛止部２２１に対してＡ２方向に掛け止められ且つＡ１方向の移動（開放移動）において当該掛け止め状態が解除されるようになっている。 The base end 32 has an insertion connection portion 321 into which the other end 22 of the main body 2 is inserted to allow the opening/closing portion 3 to move open and close in the A direction.
The insertion coupling portion 321 has an arrangement hole 320 that opens on the inside, that is, the storage space 10 side, and in which the other end 22 of the main body portion 2 is arranged to allow the opening/closing movement of the opening/closing portion 3. A second latched portion 323 is arranged in the arrangement hole 320. In this embodiment, the arrangement hole 320 is formed as a through hole 322 that penetrates from the inside, that is, the storage space 10 side, to the outside, that is the opposite side, and a second latched portion 323 is formed in a portion of the through hole 322 near the inner periphery of the connector 1, protruding from an inner wall 322A that forms the through hole 322 so as to be latched onto the other end 22 of the main body portion 2 in the opening closing position P1, and a latched protrusion 323A that protrudes from the inside, that is, the storage space 10 side, to the outside, that is the opposite side, is formed at the tip of the second latched portion 323. Furthermore, the portion of the inner wall 322A of the insertion coupling portion 321 where the second hooking portion 221 is located between the second hooked portion 323 and the second hook portion 324 serves as an abutting portion 324 that abuts against the outer surface 221A of the second hooking portion 221 at the opening-open position P2. The abutting portion 324 abuts against the outer surface 221A of the coupler 1, thereby restricting the opening-closing portion 3 from moving in the A1 direction beyond the opening-open position P2. The distance between the second hooking portion 221 and the abutting portion 324 is wide enough to form a gap 325 between the second hooking portion 221 and the abutting portion 324. The formation of the gap 325 allows the opening-closing portion 3 to swing by the amount of the gap 325. This allows the opening-closing portion 3 to move smoothly in the A direction.
This second hooked portion 323 is hooked in the A2 direction relative to the second hooking portion 221 by the hooked protrusion 323A being engaged with the locking protrusion 223 at the opening closing position P1, and this hooked state is released when moved in the A1 direction (opening movement).

　弾性変形部４は、本体部２と一体成形されており、収容空間１０から離間するように本体部２から外側（連結具１の径方向における外側）に突出する起立部４１と、起立部４１の先端から開閉部３側に向かって湾曲形状に折曲されて延びる連続部４２とを有して略Ｊ字状に形成されており、Ｘ軸方向における他方側の位置内に配置されている。また、弾性変形部４は、延設部２３に対して一定の空間を隔てて配置されており、弾性変形部４の弾性変形スペースを確保している。この弾性変形部４は、開閉部３を開口閉鎖位置Ｐ１においてもＡ２方向に常時付勢しており、また、その弾性変形によって開閉部３をＢ方向へ若干揺動可能に保持している。 The elastically deforming portion 4 is molded integrally with the main body portion 2 and has a generally J-shaped configuration with an upright portion 41 that protrudes outward from the main body portion 2 (outward in the radial direction of the connector 1) away from the storage space 10, and a continuous portion 42 that bends in a curved shape and extends from the tip of the upright portion 41 toward the opening/closing portion 3, and is located on the other side in the X-axis direction. The elastically deforming portion 4 is also located a certain distance away from the extension portion 23, ensuring space for elastic deformation of the elastically deforming portion 4. This elastically deforming portion 4 constantly biases the opening/closing portion 3 in the A2 direction even when the opening is in the closed position P1, and its elastic deformation allows the opening/closing portion 3 to swing slightly in the B direction.

　前述した連結具１は、図１に示す状態が初期状態とされる。開閉部３は開口１１よりも外側に配置され、弾性変形部４は、本体部２よりも曲率が小さく形成される。
　図１に示す連結具１は、貫通孔３２２に対して第二掛止部２２１を差し込み且つ第一被掛止部３１１を第一掛止部２１１よりも収容空間１０側に配置することで組み立てる。図２から図４では、組み立てた状態で開閉部３が開口閉鎖位置Ｐ１に配置された閉鎖状態の連結具１を示している。 The initial state of the connector 1 described above is shown in Fig. 1. The opening/closing portion 3 is disposed outside the opening 11, and the elastically deforming portion 4 is formed to have a smaller curvature than the main body portion 2.
The connector 1 shown in Fig. 1 is assembled by inserting the second hooking portion 221 into the through-hole 322 and positioning the first hooked portion 311 closer to the accommodation space 10 than the first hooking portion 211. Figs. 2 to 4 show the connector 1 in a closed state in the assembled state, with the opening/closing portion 3 positioned at the opening closing position P1.

　前述した連結具１における開口１１の開閉は次のように行われる。
（開放動作）
　開閉部３が開口閉鎖位置Ｐ１に配置されて閉鎖状態（全閉状態）にある連結具１において、鉤状の係合部２１３，３１３の係合を解除する。具体的には、本体部２を収容空間１０側に若干撓めたり、弾性変形部４によってＢ方向にも若干揺動可能に保持される開閉部３を本体部２の一端部２１側に接近させたりすることで、鉤状の係合部２１３，３１３の係合を解除する。これにより、開閉部３はＡ１方向に開放移動可能な状態となる。続いて、開閉部３を操作することで当該開閉部３を弾性変形部４の付勢に抗してＡ１方向に開放移動することで、開口１１を開放する。
　次に、開閉部３が更にＡ１方向に開放移動されて図５に示す開口開放位置Ｐ２に配置される際、開閉部３の当接部３２４が本体部２の第二掛止部２２１の外面２２１Ａに当接し且つ開閉部３の基端部３２が本体部２の段部２２２に当接することで、開閉部３が開口開放位置Ｐ２を超えてＡ１方向に開放移動することを規制する。このため、開閉部３が本体部２の内側部分（内周部分）に当たることなく開口開放位置Ｐ２に配置された状態で開放状態（全開状態）となる。このように開放状態とすることで、被連結体としての物品の紐などの部位を開口１１から収容空間１０に入れることができ、連結具１を物品に連結したり、物品同士を連結したり、物品の部分同士を連結したりできる。なお、開閉部３は開口閉鎖位置Ｐ１と開口開放位置Ｐ２との間でＡ方向に開閉移動可能である。
（閉鎖動作）
　開放状態とした連結具１において、開閉部３の開放操作を止めると、開閉部３は弾性変形部４の付勢によってＡ２方向に閉鎖移動する。続いて、開閉部３の先端部３１における溝部３１５に本体部２の第一掛止部２１１を配置し、第一被掛止部３１１の当接板部３１２を第一掛止部２１１の内面２１１Ａに当接ないし当接し得る状態にし且つ鉤状の係合部３１３を鉤状の係合部２１３に係合することで、開閉部３を開口閉鎖位置Ｐ１に配置して閉鎖状態とする。このとき、被係止突部３２３Ａは係止突部２２３に係止されて第二被掛止部３２３は第二掛止部２２１に掛け止められた状態となる。このように、閉鎖状態では、第一被掛止部３１１が第一掛止部２１１に掛け止められ且つ第二被掛止部３２３は貫通孔３２２に差し込まれた状態の第二掛止部２２１に掛け止められた状態となる。このため、例えば開閉部の基端部が本体部に軸支される場合と比べて、特に、第二掛止部２２１を差込連結部３２１に深く差し込むことができ且つ前述した構成の第二被掛止部３２３を第二掛止部２２１に掛け止めることができて、Ａ２方向の力や連結具１に捻り力に対する強度を向上することができる。
　ここで、連結具１は、開口閉鎖位置Ｐ１において第一被掛止部３１１が第一掛止部２１１に掛け止められ且つ第二被掛止部３２３が第二掛止部２２１に掛け止められることで、閉鎖状態としているが、第一被掛止部３１１および第二被掛止部３２３と第一掛止部２１１および第二掛止部２２１とのそれぞれが、必ずしも互いに当接していなくても掛止め状態であればよい。例えば、第一被掛止部３１１および第一掛止部２１１の間と、第二被掛止部３２３および第二掛止部２２１の間とのうちのいずれか一方の間に隙間が形成されていても、Ａ２方向に力が加わった際に、当該隙間を形成していた第一被掛止部３１１および第一掛止部２１１と、第二被掛止部３２３および第二掛止部２２１とのうちのいずれか一方が互いに当接して掛止め状態となればよい。
　また、本実施形態では、閉鎖状態において弾性変形部４の外径輪郭は、本体部２の外径輪郭線（仮想線）に沿って配置されており、本体部２および開閉部３と協働して円環状の連結具１を呈する。 The opening 11 in the connector 1 is opened and closed as follows.
(Opening operation)
When the opening-closing unit 3 is positioned at the opening closing position P1 and in a closed state (fully closed state), the hook-shaped engaging units 213, 313 are disengaged from the connector 1. Specifically, the hook-shaped engaging units 213, 313 are disengaged by slightly bending the main body 2 toward the accommodation space 10 or by moving the opening-closing unit 3, which is held by the elastic deformation unit 4 so that it can swing slightly in direction B, closer to one end 21 of the main body 2. This allows the opening-closing unit 3 to move open in direction A1. Next, the opening-closing unit 3 is operated to move open in direction A1 against the bias of the elastic deformation unit 4, thereby opening the opening 11.
Next, when the opening/closing unit 3 is further moved in the A1 direction to the opening-open position P2 shown in FIG. 5 , the abutment portion 324 of the opening/closing unit 3 abuts the outer surface 221A of the second hook portion 221 of the main body 2, and the base end 32 of the opening/closing unit 3 abuts the step portion 222 of the main body 2, thereby restricting the opening/closing unit 3 from moving in the A1 direction beyond the opening-open position P2. Therefore, the opening/closing unit 3 is in an open state (fully open state) when positioned at the opening-open position P2 without abutting the inner portion (inner periphery) of the main body 2. This open state allows a portion of an article, such as a string, to be connected through the opening 11 into the storage space 10, allowing the connector 1 to be connected to an article, to connect articles to each other, or to connect parts of articles to each other. The opening/closing unit 3 can be moved in the A direction between the opening-closing position P1 and the opening-open position P2.
(Closing operation)
When the opening operation of the opening-closing part 3 of the connector 1 in the open state is stopped, the opening-closing part 3 moves in the closing direction A2 due to the bias of the elastic deformation part 4. Next, the first hooking part 211 of the main body part 2 is placed in the groove part 315 at the tip end 31 of the opening-closing part 3, and the abutment plate part 312 of the first hooked part 311 is brought into contact with or able to contact the inner surface 211A of the first hooking part 211, and the hook-shaped engaging part 313 is engaged with the hook-shaped engaging part 213, thereby placing the opening-closing part 3 in the opening-closing position P1 and entering the closed state. At this time, the hooked protrusion 323A is engaged with the locking protrusion 223, and the second hooked part 323 is hooked to the second hooking part 221. Thus, in the closed state, the first hooked portion 311 is hooked to the first hooking portion 211, and the second hooked portion 323 is hooked to the second hooking portion 221 inserted into the through-hole 322. Therefore, compared to when the base end of the opening/closing portion is pivotally supported on the main body, for example, the second hooking portion 221 can be inserted deeply into the insertion connecting portion 321, and the second hooked portion 323 having the above-described configuration can be hooked to the second hooking portion 221, thereby improving the strength of the connector 1 against forces in the A2 direction and twisting forces.
Here, the connector 1 is in the closed state when the first hooked portion 311 is hooked on the first latching portion 211 and the second hooked portion 323 is hooked on the second latching portion 221 in the opening-closing position P1, but the first hooked portion 311 and the second hooked portion 323 do not necessarily have to abut against each other as long as they are in the hooked state. For example, even if a gap is formed between the first hooked portion 311 and the first latching portion 211 and between the second hooked portion 323 and the second latching portion 221, it is sufficient that when a force is applied in the A2 direction, either the first hooked portion 311 and the first latching portion 211 or the second hooked portion 323 and the second latching portion 221 that formed the gap abut against each other to form the hooked state.
In addition, in this embodiment, in the closed state, the outer diameter contour of the elastic deformation portion 4 is arranged along the outer diameter contour line (virtual line) of the main body portion 2, and cooperates with the main body portion 2 and the opening/closing portion 3 to form a circular connecting device 1.

　なお、開放状態の連結具１において、開閉部３がＡ１方向に開放移動することで、当接板部３１２は第一掛止部２１１の内面２１１Ａから離間して第一被掛止部３１１と第一掛止部２１１との掛り合いが解除されると共に、被係止突部３２３Ａが係止突部２２３から外れて第二被掛止部３２３と第二掛止部２２１との掛り合いが解除される。 In addition, when the connector 1 is in the open state, the opening/closing section 3 moves open in the A1 direction, causing the abutment plate section 312 to move away from the inner surface 211A of the first hooking section 211, disengaging the first hooked section 311 from the first hooking section 211, and the hooked protrusion 323A to come off the hooking protrusion 223, disengaging the second hooked section 323 from the second hooking section 221.

　以上の連結具１は、鞄の中などに装着され、各種の物品やその部位が掛けられて用いられる。 The above-mentioned connector 1 is attached to the inside of a bag or the like and can be used to hang various items or parts of items.

［変形例］
　前記実施形態では、本体部２は、Ｃ字状に形成されているが、これに限らず、被連結体を掛けられる形状であれば、コの字状、Ｊ字状などの他の形状に形成されていてもよい。 [Modification]
In the above embodiment, the main body 2 is formed in a C-shape, but this is not limited to this and it may be formed in other shapes such as a U-shape or a J-shape as long as the shape allows the connected object to be hung on it.

　前記実施形態では、差込連結部３２１は、開閉部３の他端部２２が配置される配置穴部３２０として、鈎針形状の第二掛止部２２１が差し込まれる貫通孔３２２を有しており、開放状態では、第二掛止部２２１の先端が貫通孔３２２から外側に突き出て配置されるようになっているが（図５参照）、これに限らない。差込連結部３２１は、他端部２２を適切に配置可能であればよく、例えば、差込連結部３２１は、配置穴部３２０として、第二掛止部２２１が差し込まれる有底の凹み部を有して形成されていてもよい。また、前述した凹み部の底部には、外側に貫通する小さな孔が形成されていてもよい。 In the above embodiment, the plug-in coupling portion 321 has a through-hole 322 into which the hook-shaped second hook portion 221 is inserted, as the arrangement hole 320 in which the other end 22 of the opening/closing portion 3 is arranged, and in the open state, the tip of the second hook portion 221 is arranged to protrude outward from the through-hole 322 (see Figure 5), but this is not limited to this. The plug-in coupling portion 321 may have any shape as long as it can appropriately arrange the other end 22. For example, the plug-in coupling portion 321 may be formed with a bottomed recess as the arrangement hole 320 into which the second hook portion 221 is inserted. Furthermore, a small hole penetrating to the outside may be formed in the bottom of the aforementioned recess.

　前記実施形態では、第二被掛止部３２３には被係止突部３２３Ａが形成され、第一掛止部２１１には係止突部２２３が形成されており、閉鎖状態で被係止突部３２３Ａが係止突部２２３に係止されるようなっているが、これに限らず、当該係止がなくても、第二被掛止部３２３が第一掛止部２１１に当接してＡ２方向に十分に掛け止められる場合には、当該被係止突部３２３Ａおよび係止突部２２３の構成を省略してもよい。 In the above embodiment, the second latched portion 323 is formed with a latched protrusion 323A, and the first latching portion 211 is formed with a latching protrusion 223, and when closed, the latched protrusion 323A is latched with the latching protrusion 223. However, this is not limited to this, and even without this latching, if the second latched portion 323 abuts against the first latching portion 211 and is sufficiently latched in the A2 direction, the latched protrusion 323A and the latching protrusion 223 may be omitted.

　前記実施形態では、差込連結部３２１の当接部３２４が開口開放位置Ｐ２で本体部２の外面２２１Ａに当接して、開閉部３の開放移動を規制するようになっているが、これに限らず、例えば、開口開放位置Ｐ２で開閉部３が本体部２の他の箇所に当接してその開放移動が規制される場合には、当接部３２４は、開口開放位置Ｐ２で外面２２１Ａに対して非当接状態とされてもよい。 In the above embodiment, the abutment portion 324 of the insertion coupling portion 321 abuts against the outer surface 221A of the main body 2 at the opening-open position P2, restricting the opening movement of the opening/closing unit 3. However, this is not limited to this. For example, if the opening/closing unit 3 abuts against another part of the main body 2 at the opening-open position P2, restricting its opening movement, the abutment portion 324 may be in a non-abutting state against the outer surface 221A at the opening-open position P2.

　前記実施形態では、当接部３２４が当接する本体部２の外面２２１Ａには、当該当接部３２４の移動軌跡から外れるように凹んだ凹部２２１Ｂが形成されているが、これに限らず、開閉部３の開閉移動領域を十分に得られる場合には、当該凹部２２１Ｂの構成を省略してもよい。 In the above embodiment, the outer surface 221A of the main body 2, with which the abutment portion 324 abuts, is formed with a recessed portion 221B that is recessed so as to deviate from the movement trajectory of the abutment portion 324. However, this is not limited to this, and if a sufficient opening and closing movement area of the opening/closing portion 3 can be obtained, the recessed portion 221B may be omitted.

　前記実施形態では、開口開放位置Ｐ２で開閉部３のうち差込連結部３２１の差込側の部分に当接する段部２２２が形成されているが、これに限らず、開口開放位置で開閉部３が他の箇所に当接してその開放移動が規制される場合には、段部２２２は開口開放位置Ｐ２で外面２２１Ａに対して非当接状態とされてもよい。 In the above embodiment, a step 222 is formed that abuts against the insertion side portion of the opening/closing unit 3, the insertion coupling portion 321, at the opening-open position P2. However, this is not limited to this. If the opening/closing unit 3 abuts against another portion at the opening-open position, restricting its opening movement, the step 222 may be in a non-abutting state against the outer surface 221A at the opening-open position P2.

　前記実施形態では、開口開放位置Ｐ２では、第二被掛止部３２３の先端が本体部２の他端部２２に対して非当接状態であるが、これ限らず、開口開放位置Ｐ２で第二被掛止部３２３の先端が本体部２の他端部２２に対して当接して、開閉部のＡ１方向の開放移動を規制するようになっていてもよい。 In the above embodiment, the tip of the second latched portion 323 is not in contact with the other end 22 of the main body 2 at the opening-open position P2, but this is not limited thereto. The tip of the second latched portion 323 may be in contact with the other end 22 of the main body 2 at the opening-open position P2, thereby restricting the opening movement of the opening/closing portion in the A1 direction.

　前記実施形態では、連結具１をカラビナとして構成したが、このほか、なす環などで構成されてもよい。 In the above embodiment, the connector 1 is configured as a carabiner, but it may also be configured as a ring or other device.

［作用効果］
（１）本実施形態の連結具１は、被連結体が通される収容空間１０を形成し且つ当該収容空間１０を連通する開口１１を一端部２１および他端部２２で区画する本体部２と、前記開口１１を開閉する開閉部３と、前記開閉部３が開閉移動可能となるように前記本体部２および前記開閉部３を接続する弾性変形部４とを一体的に有する連結具１であって、前記開閉部３は、前記開口１１を閉鎖する開口閉鎖位置Ｐ１で前記本体部２の一端部２１に対してＡ２方向に掛け止められ且つＡ１方向の移動において当該掛け止め状態が解除される第一被掛止部３１１と、当該開閉部３の開閉移動を許容可能に前記本体部２の他端部２２が差し込まれる差込連結部３２１とを有し、前記差込連結部３２１には、前記開口閉鎖位置Ｐ１で前記本体部２の他端部２２に対してＡ２方向に掛け止められ且つＡ１方向の移動において当該掛け止め状態が解除される第二被掛止部３２３が形成される。
　本実施形態の連結具１によれば、開閉部３の差込連結部３２１に本体部２の他端部２２が差し込まれることで当該開閉部３が本体部２に対して開閉移動可能に組み合わされた連結状態とされる上、開口閉鎖位置Ｐ１で、開閉部３の第一被掛止部３１１が本体部２の一端部２１に対してＡ２方向に掛け止められると共に第二被掛止部３２３が本体部２の他端部２２に対してＡ２方向に掛け止められるので、例えば開閉部３が本体部２に軸支される場合と比べて、連結具１の外側に開閉部３を外す方向に対する強度の向上を図ることができる。また、第二被掛止部３２３を掛け止める本体部２の他端部２２が差込連結部３２１に差し込まれるので、例えば開閉部３が本体部２に軸支される場合と比べて、連結具１の捻り方向に対する強度の向上を図ることができる。加えて、差込連結部３２１には、開閉部３の開閉移動を許容可能に本体部２の他端部２２が差し込まれるので、例えば、開閉部の基端部が軸支される場合と比べて、弾性変形部４の全体を利用して開閉部３を開閉移動でき、当該弾性変形部４の一部だけに集中的に負荷がかかることを抑制できて連結具１の強度の向上を図り得る。
　このように連結具１によれば、強度の向上を図ることができて開閉部３の本体部２に対する連結状態を好適に保ち得る。（２）本実施形態の連結具１では、前記本体部２は、前記開口１１を区画してフック状に形成され、前記本体部２の前記一端部２１には、Ａ２方向において前記第一被掛止部３１１に対して解除可能に掛かり合う第一掛止部２１１が形成され、前記本体部２の前記他端部２２には、Ａ２方向において前記第二被掛止部３２３に対して解除可能に掛かり合う第二掛止部２２１が形成される。
　このような構成によれば、開閉部３が開口閉鎖位置Ｐ１に配置される場合には当該開閉部３の第一被掛止部３１１および第二被掛止部３２３が本体部２の第一掛止部２１１および第二掛止部２２１に掛けられることで、開閉部３が本体部２に強固に連結された状態となって閉鎖状態における連結具１の強度を向上でき、また、開閉部３が開口閉鎖位置Ｐ１から開放移動した位置に配置された場合には、前記掛けられた状態は解除されるので、例えば開閉部３が軸支される場合と比べて、開閉部３の開閉移動において回動以外の揺動をも許容し得る構成にできる。
（３）本実施形態の連結具１では、前記本体部２は、前記弾性変形部４との接続位置から前記開口１１側に延設される延設部２３を有し、前記弾性変形部４は、前記延設部２３の外側において当該延設部２３に沿って延び、前記本体部２の前記他端部２２は、前記延設部２３の先端部で構成される。
　このような構成によれば、弾性変形部４を介して本体部２および開閉部３が一体的に連続する連結具１において弾性変形部４を長尺に形成できるので、開閉部３が揺動可能な領域を広げることができる。このため、開閉部３の差込連結部３２１に対して本体部２の他端部２２を容易に差し込むことができ、また、開閉部３の開閉移動に伴う回動以外の揺動をも柔軟に許容可能となって開閉部３に円滑な開閉移動を行わせ得る。
（４）前記差込連結部３２１は、前記収容空間１０側である内側で開口し且つ前記開閉部３の開閉移動を許容可能に前記本体部２の前記他端部２２が配置される配置穴部３２０を有し、前記配置穴部３２０には、前記第二被掛止部３２３が配置される。
　このような構成によれば、本体部２の他端部２２を内側から差込連結部３２１に差し込んで配置穴部３２０に配置することで、開閉部３を本体部２に好適に連結し得る。
（５）本実施形態の連結具１では、前記配置穴部３２０は、前記収容空間１０側である内側から反対側である外側に貫通すると共に前記開閉部３の開閉移動を許容可能に前記本体部２の前記他端部２２が差し込まれる貫通孔３２２で形成され、
　前記第二被掛止部３２３は、前記開口閉鎖位置Ｐ１で前記本体部２の前記他端部２２に掛け止められるように前記貫通孔３２２を形成する内壁３２２Ａに形成される。
　このような構成によれば、本体部２の他端部２２が差し込まれる貫通孔３２２を差込連結部３２１に形成することで、例えば本体部２の他端部２２が差し込まれる凹み部を差込連結部３２１に形成する場合よりも開閉部３を小型に形成し得ると共に開閉部３を成形するための金型の形状や構成の複雑化を回避し得る。
（６）本実施形態の連結具１では、前記本体部２の前記他端部２２には、前記収容空間１０側である内側に向けて突出する係止突部２２３が形成され、前記第二被掛止部３２３には、前記内側とは反対側である外側に向けて突出し且つ前記開口閉鎖位置Ｐ１で前記係止突部２２３に係止される被係止突部３２３Ａが形成される。
　このような構成によれば、開口閉鎖位置Ｐ１で被係止突部３２３Ａが係止突部２２３に係止されるので、連結具１の外側に開閉部３を外す方向の強度を向上できると共に、本体部２の他端部２２が開閉部３の差込連結部３２１から不意に抜出することを抑制できる。
（７）本実施形態の連結具１では、前記差込連結部３２１は、前記開口１１を開放する開口開放位置Ｐ２で前記本体部２の外面２２１Ａに当接する当接部３２４を有する。
　このような構成によれば、開閉部３が開口開放位置Ｐ２を越えて過度に開放移動することを抑制できる。
（８）本実施形態の連結具１では、前記当接部３２４が当接する前記本体部２の外面２２１Ａには、前記当接部３２４の移動軌跡から外れるように凹んだ凹部２２１Ｂが形成される。
　このような構成によれば、開閉部３が開放移動する際に移動する当接部３２４を凹部２２１Ｂで回避できるので、当該当接部３２４が外面２２１Ａに当接する位置を収容空間１０側に深く入り込んだ位置にすることができ、このため、開閉部３の開閉移動領域を広げることができる。
（９）本実施形態の連結具１では、前記本体部２の前記他端部２２には、前記開口１１を開放する開口開放位置Ｐ２で前記開閉部３のうち前記差込連結部３２１の差込側の部分に当接する段部２２２が形成される。
　このような構成によれば、開閉部３が開口開放位置Ｐ２を越えて過度に開放移動することを抑制できる。 [Action and effect]
(1) The connector 1 of this embodiment is a connector 1 that integrally includes a main body 2 that defines a storage space 10 through which a connected object is passed and that defines an opening 11 that communicates with the storage space 10 at one end 21 and the other end 22; an opening/closing unit 3 that opens and closes the opening 11; and an elastic deformation unit 4 that connects the main body 2 and the opening/closing unit 3 so that the opening/closing unit 3 can move open and closed. The opening/closing unit 3 has a first hooked portion 311 that is hooked in the A2 direction to the one end 21 of the main body 2 at an opening closing position P1 that closes the opening 11 and whose hooked state is released when moved in the A1 direction, and an insertion connecting portion 321 into which the other end 22 of the main body 2 is inserted to allow the opening/closing unit 3 to move open and closed. The insertion connecting portion 321 is formed with a second hooked portion 323 that is hooked in the A2 direction to the other end 22 of the main body 2 at the opening closing position P1 and whose hooked state is released when moved in the A1 direction.
According to the coupler 1 of this embodiment, the other end 22 of the main body 2 is inserted into the plug-in coupling portion 321 of the opening-closing portion 3, thereby bringing the opening-closing portion 3 into a coupled state in which it can be opened and closed relative to the main body 2. In addition, at the opening closed position P1, the first latched portion 311 of the opening-closing portion 3 is latched in the A2 direction relative to the one end 21 of the main body 2, and the second latched portion 323 is latched in the A2 direction relative to the other end 22 of the main body 2. This improves the strength of the coupler 1 in the direction in which the opening-closing portion 3 is removed from the outside, compared to, for example, when the opening-closing portion 3 is pivotally supported on the main body 2. Furthermore, because the other end 22 of the main body 2, which latches the second latched portion 323, is inserted into the plug-in coupling portion 321, the strength of the coupler 1 in the torsional direction can be improved compared to, for example, when the opening-closing portion 3 is pivotally supported on the main body 2. In addition, the other end 22 of the main body 2 is inserted into the insertion connecting portion 321 in a manner that allows the opening and closing movement of the opening and closing portion 3, so that, compared to when the base end of the opening and closing portion is journaled, the entire elastic deformation portion 4 can be used to open and close the opening and closing portion 3, and concentrated load on only a portion of the elastic deformation portion 4 can be prevented, thereby improving the strength of the connecting device 1.
In this way, the connector 1 can improve strength and maintain a suitable connection state of the opening/closing part 3 to the main body part 2. (2) In the connector 1 of this embodiment, the main body part 2 is formed in a hook shape by defining the opening 11, and the one end part 21 of the main body part 2 is formed with a first hooking part 211 that releasably engages with the first hooked part 311 in the A2 direction, and the other end part 22 of the main body part 2 is formed with a second hooking part 221 that releasably engages with the second hooked part 323 in the A2 direction.
According to this configuration, when the opening/closing part 3 is positioned in the opening closing position P1, the first hooking part 311 and the second hooking part 323 of the opening/closing part 3 are hooked onto the first hooking part 211 and the second hooking part 221 of the main body part 2, thereby firmly connecting the opening/closing part 3 to the main body part 2 and improving the strength of the connecting device 1 in the closed state.Furthermore, when the opening/closing part 3 is positioned in a position moved to an open position from the opening closing position P1, the hooked state is released, so that the configuration can allow for swinging movements other than rotation when the opening/closing part 3 moves to the opening and closing position, compared to when the opening/closing part 3 is supported on a shaft, for example.
(3) In the connector 1 of this embodiment, the main body portion 2 has an extension portion 23 extending from the connection position with the elastic deformation portion 4 toward the opening 11, the elastic deformation portion 4 extends along the extension portion 23 outside the extension portion 23, and the other end portion 22 of the main body portion 2 is formed by the tip of the extension portion 23.
According to this configuration, the elastic deformation portion 4 can be formed long in the connector 1 in which the main body portion 2 and the opening/closing portion 3 are integrally connected via the elastic deformation portion 4, thereby expanding the range over which the opening/closing portion 3 can swing. This allows the other end 22 of the main body portion 2 to be easily inserted into the insertion coupling portion 321 of the opening/closing portion 3, and also flexibly allows for swinging other than rotation accompanying the opening/closing movement of the opening/closing portion 3, allowing the opening/closing portion 3 to move smoothly.
(4) The insertion connection portion 321 has an arrangement hole portion 320 that opens on the inside, toward the storage space 10, and in which the other end portion 22 of the main body portion 2 is arranged to allow the opening and closing movement of the opening and closing portion 3, and the second hooking portion 323 is arranged in the arrangement hole portion 320.
With this configuration, the opening/closing unit 3 can be suitably connected to the main body 2 by inserting the other end 22 of the main body 2 into the insertion connection portion 321 from the inside and arranging it in the arrangement hole 320.
(5) In the connector 1 of this embodiment, the arrangement hole 320 is formed as a through-hole 322 that penetrates from the inside, which is the accommodation space 10 side, to the outside, which is the opposite side, and into which the other end 22 of the main body 2 is inserted to allow the opening/closing movement of the opening/closing part 3,
The second latched portion 323 is formed on an inner wall 322A that forms the through hole 322 so as to be latched onto the other end portion 22 of the main body portion 2 at the opening closing position P1.
According to this configuration, by forming a through hole 322 in the plug-in connection portion 321 into which the other end portion 22 of the main body portion 2 is inserted, the opening/closing portion 3 can be made smaller than, for example, when a recessed portion in which the other end portion 22 of the main body portion 2 is inserted is formed in the plug-in connection portion 321, and it is possible to avoid complicating the shape and configuration of the mold for molding the opening/closing portion 3.
(6) In the connector 1 of this embodiment, the other end 22 of the main body 2 is formed with a locking protrusion 223 that protrudes inward toward the storage space 10, and the second latching portion 323 is formed with a locking protrusion 323A that protrudes outward, opposite the inward side, and is locked by the locking protrusion 223 at the opening closing position P1.
With this configuration, the engaging protrusion 323A is engaged with the engaging protrusion 223 at the opening closing position P1, thereby improving the strength in the direction of removing the opening/closing part 3 to the outside of the connecting device 1 and preventing the other end 22 of the main body part 2 from accidentally coming out of the insert connecting part 321 of the opening/closing part 3.
(7) In the connector 1 of this embodiment, the insertion connector 321 has the abutment portion 324 that abuts against the outer surface 221A of the main body 2 at the opening opening position P2 where the opening 11 is opened.
This configuration can prevent the opening/closing unit 3 from moving excessively beyond the opening-opening position P2.
(8) In the connector 1 of this embodiment, the outer surface 221A of the main body 2 with which the abutting portion 324 abuts is formed with a recess 221B that is recessed so as to deviate from the movement trajectory of the abutting portion 324.
With this configuration, the abutment portion 324 that moves when the opening/closing portion 3 moves to open can be avoided by the recess 221B, so the position where the abutment portion 324 abuts against the outer surface 221A can be positioned deep into the storage space 10, thereby widening the opening/closing movement range of the opening/closing portion 3.
(9) In the connector 1 of this embodiment, the other end 22 of the main body 2 is formed with a step 222 that abuts against the insertion side portion of the plug-in connecting portion 321 of the opening/closing portion 3 at the opening opening position P2 where the opening 11 is opened.
This configuration can prevent the opening/closing unit 3 from moving excessively beyond the opening-opening position P2.
