本出願人は、従来、この種の連結具として、特許文献１に示す漁網用ロープ通し環連結具を提案している。 The present applicant has conventionally proposed a fishing net rope through-ring connector shown in Patent Document 1 as this type of connector.

この漁網用ロープ通し環連結具は、連結具本体の下部に連結環を、中間部に開孔部を、上部にリング受腕を設け、この連結具本体のリング受腕に対向せしめて開閉腕の基部をリング受腕の先端に軸着して開閉腕を連結具本体の外側に開閉自在に設け、連結具本体の開孔部内に常に上方に弾圧されるように基部を連結具本体に軸着した係止腕を上下回動自在に設け、この係止腕の先端部と開閉腕の下部に係止機構を設け、開孔部の側壁に操作窓を設けて係止腕を前後左右いずれからも押し下げできるように構成したものである。 This fishing net rope through-ring connector is provided with a connecting ring at the bottom of the connector body, an opening at the middle, and a ring receiving arm at the top, with the ring receiving arm of the connecting body facing the ring arm. The base of the ring is pivotally attached to the tip of the ring receiving arm, and the open / close arm is provided on the outside of the connector body so that it can be freely opened and closed. The wearing arm is provided so that it can be pivoted up and down, a locking mechanism is provided at the tip of the locking arm and the lower part of the opening and closing arm, and an operation window is provided on the side wall of the opening portion so that the locking arm can be moved back and forth It is constructed so that it can be pushed down from the front.

また、この種の連結具は、外部からのちょっとした衝撃などで開閉腕が簡単に開いてしまう誤動作が生じないように、係止腕にはバネなどによる強力な弾圧力（付勢力）が常時作用する構成となっている。そのため、開閉腕を開く際は、例えば、ドライバー等の棒状体を開孔部に差し込み、こじ開けるような操作で強力な弾圧力で弾圧されている係止腕を押し下げて係止機構を解除することで、この開閉腕が外側に開き回動するように構成されている。 In addition, this type of connector is always subjected to a strong elastic force (biasing force) such as a spring on the locking arm to prevent malfunctions that can easily open and close the arm due to a slight external impact. It is the composition to do. Therefore, when opening the open / close arm, for example, a rod-like body such as a screwdriver is inserted into the opening, and the locking arm that is pressed with strong elastic pressure is pushed down to release the locking mechanism. Thus, the open / close arm is configured to open and rotate outward.

開閉連結環部２と開き動作阻止部３とが係合している開閉連結環部開き動作不能状態（開閉連結環部２が閉塞環状態）において、解除レバー部４の操作部９を引動操作すると、第二軸部11を回動支点として解除レバー部４が回動し、第二軸部11よりも先端側に位置する押動部８が前記引動方向と反対側に移動して、この解除レバー部４と並設状態に設けた開き動作阻止部３を、この開き動作阻止部３の係合姿勢を保持するための付勢体７の付勢力に抗して押動する。 When the opening / closing connection ring portion 2 and the opening operation blocking portion 3 are engaged with each other, the operation portion 9 of the release lever portion 4 is operated by pulling in the opening / closing connection ring portion opening disabled state (the opening / closing connection ring portion 2 is in the closed ring state). Then, the release lever portion 4 is rotated with the second shaft portion 11 as a rotation fulcrum, and the pushing portion 8 located on the distal end side with respect to the second shaft portion 11 moves to the opposite side to the pulling direction. The opening motion blocking portion 3 provided in parallel with the release lever portion 4 is pushed against the biasing force of the biasing body 7 for maintaining the engagement posture of the opening motion blocking portion 3.

この解除レバー部４の押動部８が開き動作阻止部３を押動すると、この開き動作阻止部３は第一軸部６を回動支点として回動し、先端部に設けた係合受部５が開閉連結環部２に対して離反移動して、開き動作阻止部３は、開閉連結環部２との係合状態が解除された解除姿勢になり、これにより、開閉連結環部２は開き動作可能な状態になる。 When the pushing portion 8 of the release lever portion 4 pushes the opening operation preventing portion 3, the opening operation preventing portion 3 rotates with the first shaft portion 6 as a rotation fulcrum, and an engagement receiving provided at the tip portion.

Becomes open.

この際、本発明は、解除レバー部４の軸着部10を押動部８寄りに設けた構成としたので、てこの原理により操作部９を引動操作する力が増幅されて押動部８に伝達され、押動部８は倍力作用を発揮して開き動作阻止部３を押動することとなる。 At this time, the present invention has a configuration in which the shaft mounting portion 10 of the release lever portion 4 is provided closer to the pushing portion 8. Therefore, the force for pulling the operating portion 9 is amplified by the lever principle, and the pushing portion 8 is amplified. Thus, the pushing portion 8 exerts a boosting action and pushes the opening motion preventing portion 3.

従って、例えば、この開き動作阻止部３の係合姿勢を保持する付勢力が、人が手で直接開き動作阻止部３を押動しても移動しないような強大な付勢力であっても、てこの原理により増幅された力で押動することで、人が手で引動操作する力で容易に開き動作阻止部３を押動することができることになり、操作性が向上した実用性に優れた連結具となる。 Therefore, for example, even if the urging force that holds the engagement posture of the opening operation prevention unit 3 is a strong urging force that does not move even if the person pushes the opening operation prevention unit 3 directly by hand, By pushing with the force amplified by the lever principle, it is possible to easily push the opening motion blocking unit 3 with the force of a human pulling operation, and the operability is improved and the utility is excellent. It becomes a connecting tool.

しかも、本発明は、開閉連結環部２と係合する開き動作阻止部３、及びこの開き動作阻止部３の開閉連結環部２との係合状態を解除する解除レバー部４をケース体１内に収納配設した構成としたので、開き動作阻止部３及び解除レバー部４が露出せず、外部からの衝撃による誤動作が生じる虞がなく、確実に開閉連結環部２と開き動作阻止部３との係合状態、即ち閉塞環状態が保持される実用性に優れた連結具となる。 Moreover, the present invention provides the case body 1 with the opening operation blocking portion 3 that engages with the opening / closing connection ring portion 2 and the release lever portion 4 that releases the engagement state of the opening operation blocking portion 3 with the opening / closing connection ring portion 2. Since the opening operation preventing portion 3 and the release lever portion 4 are not exposed and there is no possibility of malfunction due to external impact, the opening / closing connecting ring portion 2 and the opening operation preventing portion are surely provided. 3, that is, a connecting tool excellent in practicality in which the closed state of the closed ring is maintained.

The rotation operation is prevented, the detachment from the opening / closing connection ring portion 2 is prevented, and the engagement state with the opening / closing connection ring portion 2 is maintained.

より具体的には、本実施例の開き動作阻止部誤動作阻止機構は、ケース体１の背面壁部17の係合姿勢の開き動作阻止部３の下方に位置する箇所に挿通孔21を設け、正面壁部16にこの挿通孔21と連通する連通孔22を設け、この挿通孔21と連通孔22との間に架設するように係止部材20としての係止ピン20を挿脱自在に挿通配設した構成としている。 More specifically, the opening operation preventing portion malfunction prevention mechanism of the present embodiment is provided with an insertion hole 21 at a position located below the opening operation preventing portion 3 in the engagement posture of the back wall portion 17 of the case body 1. The front wall portion 16 is provided with a communication hole 22 that communicates with the insertion hole 21, and the locking pin 20 as the locking member 20 is removably inserted so as to be installed between the insertion hole 21 and the communication hole 22. The arrangement is arranged.

更に詳細に説明すると、係止ピン20は、先端部に雌螺子部25を形成し、基端部に操作ツマミ部26を設け、更に、この雄螺子部25と操作ツマミ部26の間の所定位置（本実施例では、操作ツマミ部26の首下から背面壁部17の壁厚分の間隔をおいた位置）に溝を周設し、この溝にＯリング27を装着した構成とし、また、正面壁部16の連通孔22には、係止ピン20が螺着する雌螺子を形成した構成として、背面壁部17の連通孔21から係止ピン20を挿通し、雄螺子部25を連通孔22に螺着すると、Ｏリング27が圧入により連通孔21を通過して抜け止め状態で開き動作阻止部３の直下に正面壁部16、背面壁部17間に架設され、開き動作阻止部３が開閉連結環部２に対して離反移動しようとしても、この係止ピン20に当接して離反移動が阻止される構成としている。尚、係止ピン20の抜け止め構造は、本実施例に限定されるものではないし、また、開き動作阻止部誤動作阻止機構を設けない構成（係止ピン20が無い構成）としても良い。 More specifically, the locking pin 20 has a female screw portion 25 formed at the distal end portion, an operation knob portion 26 provided at the base end portion, and a predetermined gap between the male screw portion 25 and the operation knob portion 26. In this embodiment, a groove is provided at a position (a position corresponding to the wall thickness of the rear wall portion 17 from the neck of the operation knob portion 26), and an O-ring 27 is attached to the groove. In the communication hole 22 of the front wall portion 16, a female screw to which the locking pin 20 is screwed is formed, and the locking pin 20 is inserted from the communication hole 21 of the back wall portion 17 so that the male screw portion 25 is inserted. When screwed into the communication hole 22, the O-ring 27 passes through the communication hole 21 by press-fitting and is installed between the front wall portion 16 and the rear wall portion 17 immediately below the opening operation blocking portion 3 in a state of being prevented from coming off. Even if the portion 3 is about to move away from the opening / closing connecting ring portion 2, it is configured to abut against the locking pin 20 to prevent the separation movement. In addition, the retaining structure of the locking pin 20 is not limited to the present embodiment, and may be configured not to be provided with a malfunction prevention mechanism for the opening operation prevention unit (configuration without the locking pin 20).

また、開閉連結環部２は、所定形状に曲成した固定腕部２ａと回動腕部２ｂとから成る構成とし、固定腕部２ａは、一端をケース体１の下部側に連接し、他端に枢着部と設けた構成とし、また、回動腕部２ｂは、一端を固定腕部２ａの枢着部に連結して回動自在に設けると共に、他端に開き動作阻止部３に設けた係合受部５と係合する係合部23を設けた構成として、この回動腕部２ｂの係合部23が開き動作阻止部３の係合受部５に係合することで閉塞環状態となり、係合部23が係合受部５から離脱することで開放環状態となるように構成している。 The open / close connecting ring portion 2 is composed of a fixed arm portion 2a and a rotating arm portion 2b that are bent into a predetermined shape. The fixed arm portion 2a has one end connected to the lower side of the case body 1 and the like. The pivot arm 2b is provided with a pivot attachment at the end, and the pivot arm 2b is pivotally provided with one end connected to the pivot joint of the fixed arm 2a, and is opened at the other end. As a configuration in which an engaging portion 23 that engages with the provided engaging receiving portion 5 is provided, the engaging portion 23 of the rotating arm portion 2 b is engaged with the engaging receiving portion 5 of the opening operation preventing portion 3. It is configured to be in a closed ring state and to be in an open ring state when the engaging portion 23 is disengaged from the engagement receiving portion 5.

また、固定連結環部15は、半円環状に形成し、両端部をケース体１の上部に連結して形成した構成としている。 Further, the fixed connection ring portion 15 is formed in a semi-annular shape and has both ends connected to the upper portion of the case body 1.

上述のように構成した本実施例に係る連結具の作用・効果について以下に説明する。 The operation and effect of the connector according to the present embodiment configured as described above will be described below.

開閉連結環部２を開放環状態とする際は、ケース体１の外部に配された把持部19を手で把持して引き操作する、若しくは指掛け部19に指を掛けて引き操作する。 When the open / close connecting ring portion 2 is in an open ring state, the grip portion 19 disposed outside the case body 1 is gripped by a hand and pulled, or the finger hook portion 19 is pulled and operated.

この把持部19（指掛け部19）を引き操作することでワイヤー24が引っ張られ、このワイヤー24を連結した操作部９が引動操作される。 By pulling the grip 19 (finger hook 19), the wire 24 is pulled, and the operation unit 9 connecting the wire 24 is pulled.

この操作部９が引動操作されることで、第二軸部11を回動支点として解除レバー部４が回動し、押動部８が開き動作阻止部３の先端部側を、この開き動作阻止部３に作用する付勢体７の付勢力に抗して押動する。 When the operation portion 9 is pulled, the release lever portion 4 is rotated with the second shaft portion 11 as a rotation fulcrum, and the pushing portion 8 opens the distal end side of the opening operation preventing portion 3. It pushes against the urging force of the urging body 7 acting on the blocking portion 3.

この押動部８が開き動作阻止部３を押動することで、開き動作阻止部３は、第一軸部６を回動支点として回動し、開閉連結環部２の係合部23と係合している開き動作阻止部３の係合受部５が、開閉連結環部２に対して離反移動して、係合受部５と係合部23との係合状態が解除される解除姿勢になり、これにより、開閉連結環部２は開き動作可能な状態になる。尚、本実施例では、係合受部５と係合部23との係合が解除すると、回動腕部２ｂが自重により開き回動する構成としている。 When the pushing portion 8 pushes the opening operation preventing portion 3, the opening operation preventing portion 3 rotates about the first shaft portion 6 as a rotation fulcrum, and the engaging portion 23 of the opening / closing connecting ring portion 2 The engagement receiving portion 5 of the engaged opening operation preventing portion 3 is moved away from the open / close connecting ring portion 2, and the engagement state between the engagement receiving portion 5 and the engaging portion 23 is released. Thus, the opening / closing connecting ring part 2 is in an openable state. In the present embodiment, when the engagement between the engagement receiving portion 5 and the engagement portion 23 is released, the rotating arm portion 2b is opened and rotated by its own weight.

上記操作において、本実施例は、解除レバー部４の軸着部10を押動部８寄りに設けた構成としたので、てこの原理により操作部９を引動操作する力が増幅されて押動部８に伝達され、押動部８は倍力作用を発揮して開き動作阻止部３を押動することとなる。 In the above operation, in this embodiment, since the shaft mounting portion 10 of the release lever portion 4 is provided near the pushing portion 8, the force for pulling the operating portion 9 by the lever principle is amplified and pushed. The pushing portion 8 is transmitted to the portion 8 and exerts a boosting action to push the opening operation preventing portion 3.

従って、この開き動作阻止部３の係合姿勢を保持する付勢力が、人が手で直接開き動作阻止部３を押動しても移動しないような強大な付勢力であっても、本実施例は、てこの原理により増幅された力で押動することで、人が手で引動操作する力で容易に開き動作阻止部３を押動することができることになり、これにより、極めて操作性が向上した実用性に優れた画期的な連結具となる。 Therefore, even if the urging force for maintaining the engagement posture of the opening operation preventing unit 3 is a strong urging force that does not move even if a person pushes the opening operation preventing unit 3 directly by hand, this embodiment is implemented. In the example, by pushing with the force amplified by the lever principle, the opening operation blocking portion 3 can be easily pushed by the force of the person pulling by hand, which makes it extremely easy to operate. It is an epoch-making coupling tool with improved practicality.

しかも、本実施例の連結具は、開閉連結環部２と係合する開き動作阻止部３、及びこの開き動作阻止部３の開閉連結環部２との係合状態を解除する解除レバー部４をケース体１内に収納配設した構成としたので、開き動作阻止部３及び解除レバー部４が露出せず、外部からの衝撃による誤動作が生じる虞がなく、確実に開閉連結環部２と開き動作阻止部３との係合状態、即ち閉塞環状態が保持される実用性に優れた連結具となる。 Moreover, the coupling tool of this embodiment includes an opening operation blocking portion 3 that engages with the opening / closing connection ring portion 2 and a release lever portion 4 that releases the engagement state of the opening operation blocking portion 3 with the opening / closing connection ring portion 2. Since the opening operation blocking portion 3 and the release lever portion 4 are not exposed, there is no risk of malfunction due to an external impact, and the open / close connecting ring portion 2 is securely connected to the case body 1. It becomes a connection tool excellent in practicality in which the engagement state with the opening operation preventing portion 3, that is, the closed ring state is maintained.

また、開閉連結環部２を閉塞環状態とする際は、回動腕部２ｂを開き動作阻止部３に対して押し込み操作する。 Further, when the open / close connecting ring part 2 is in the closed ring state, the rotating arm part 2 b is opened and pushed into the operation preventing part 3.

この押し込み操作により、回動腕部２ｂの先端に設けた係合部23が付勢体７の付勢力に抗して開き動作阻止部３の先端部を押動しながら摺動して係合受部５に落ち込み係合する。 By this pushing operation, the engaging portion 23 provided at the tip of the rotating arm portion 2b slides and engages while pushing the tip portion of the opening preventing portion 3 against the biasing force of the biasing body 7. The receiving part 5 is depressed and engaged.

この係合部23を係合受部５に係合させた後、係止ピン20を連通孔21より挿通し、連通孔22に螺着する。 After engaging the engagement portion 23 with the engagement receiving portion 5, the locking pin 20 is inserted through the communication hole 21 and screwed into the communication hole 22.

以上により、係合した開閉連結環部２と開き動作阻止部３とは、付勢体７の強大な付勢力によって強固に係合して閉塞環状態が保持され、更に、万が一、解除レバー部４が誤動作しても、係止ピン20により開き動作阻止部３の離反移動が阻止されるので、開閉連結環部２が開き動作することなく閉塞環状態が確実に保持される。 As described above, the engaged opening / closing connecting ring portion 2 and the opening operation blocking portion 3 are firmly engaged by the strong biasing force of the biasing body 7 to maintain the closed ring state. Even if 4 malfunctions, the locking pin 20 prevents the opening movement preventing portion 3 from moving away, so that the open / close connecting ring portion 2 does not open and the closed ring state is reliably maintained.

このように、本実施例は、開閉連結環部２を開放環状態とするための開き操作の操作性に優れると共に、開閉連結環部２の閉塞環状態を確実に保持することができる実用性に優れた画期的な連結具となる。 As described above, the present embodiment is excellent in operability of the opening operation for bringing the open / close connecting ring portion 2 into the open ring state, and can practically maintain the closed ring state of the open / close connecting ring portion 2. It is a revolutionary connecting tool with excellent performance.

尚、本発明は、本実施例に限られるものではなく、各構成要件の具体的構成は適宜設計し得るものである。 Note that the present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate.
