At this time, the four return springs 94 of the lock member 90 are bent in parallel with the bottom wall 83 of the female main body 80 as shown in FIG.
その後、差込部60を更に深く差し込むと、図１に示すように、ロック部材90の爪部93が、差込部60のロック穴61にはまり込み、４本の復帰バネ94の蓄積されていたバネ復元力により、ロック部材90の全体が上昇する。
その結果、左右の雄部材30の差込部60が、図１に示すように、雌本体80の各差込口81内にロックされる。
Thereafter, when the insertion portion 60 is inserted further deeply, the claw portion 93 of the lock member 90 is fitted into the lock hole 61 of the insertion portion 60 and the four return springs 94 are accumulated as shown in FIG. Due to the spring restoring force, the entire locking member 90 is raised.
As a result, the insertion portions 60 of the left and right male members 30 are locked in the respective insertion ports 81 of the female main body 80 as shown in FIG.
一方、左右の雄部材30を外す際には、雌部材40の解除ボタン91を押し込めば良い。
解除ボタン91を押し込むと、図１２に示すように、ロック部材90の全体が下降し、ロック部材90の４本の復帰バネ94が、雌本体80の底壁83と平行に撓み、バネ力を蓄積する。
同時に、４本の押圧バネ95が、図１２に示すように、ロック部材90の全体の下降に伴って、雌本体80の底壁83に押されて、一層深く山形或いは逆Ｖ方に屈曲して、バネ力を蓄積する。
On the other hand, when removing the left and right male members 30, the release button 91 of the female member 40 may be pushed.
When the release button 91 is pushed in, as shown in FIG. 12, the lock member 90 as a whole is lowered, and the four return springs 94 of the lock member 90 bend in parallel with the bottom wall 83 of the female body 80, and the spring force is increased. accumulate.
At the same time, as shown in FIG. 12, the four pressing springs 95 are pushed by the bottom wall 83 of the female main body 80 as the entire locking member 90 is lowered, and are bent deeper into a mountain shape or a reverse V direction. To accumulate spring force.
そして、爪部93がロック穴61から外れると、図１３に示すように、蓄積されていたバネ復元力により、４本の押圧バネ95の各先端部が差込部60の先端部の端面を差込口81の外側に向かって少し押し出す。
これにより、左右の雄部材30の差込部60が、雌本体80から外れる。
その後、図８に示すように、４本の復帰バネ94の蓄積されていたバネ復元力により、ロック部材90の全体が上昇して復帰する。
（第２の実施の形態の一例）
つぎに、図１４〜１９を用いて、本発明の第２の実施の形態の一例について説明する。
Then, when the claw portion 93 is removed from the lock hole 61, as shown in FIG. 13, due to the accumulated spring restoring force, the respective distal end portions of the four pressing springs 95 move the end surface of the distal end portion of the insertion portion 60. Push out a little toward the outside of the slot 81.
As a result, the insertion portions 60 of the left and right male members 30 are detached from the female main body 80.
Thereafter, as shown in FIG. 8, the entire lock member 90 is raised and returned by the spring restoring force accumulated in the four return springs 94.
(Example of second embodiment)
Next, an example of the second embodiment of the present invention will be described with reference to FIGS.
本実施の形態は、図１４〜１５に示すように、左右の肩ベルト23を加えて、５点式シートベルトに使用可能な連結装置10を提供しようとするものである。
すなわち、雄部材30には、図１６〜１９に示すように、雌部材40との間に、左右の肩ベルト23をそれぞれ固定可能な第２のベルト固定部100をそれぞれ設けている。
第２のベルト固定部100は、図１６〜１９に示すように、雌部材40のベルト固定部50から、差込部60と同方向に棒状に延び、その先端部には雌部材40に向かってＬ字状に屈曲して短く延びるストッパー101を設けている。
In this embodiment, as shown in FIGS. 14 to 15, the left and right shoulder belts 23 are added to provide a connecting device 10 that can be used for a five-point seat belt.
That is, as shown in FIGS. 16 to 19, the male member 30 is provided with a second belt fixing portion 100 that can fix the left and right shoulder belts 23 between the male member 30 and the female member 40.
16 to 19, the second belt fixing part 100 extends from the belt fixing part 50 of the female member 40 in a bar shape in the same direction as the insertion part 60, and the tip part thereof faces the female member 40. A stopper 101 that is bent in an L shape and extends shortly is provided.
これに対し、左右の肩ベルト23には、図１６に示すように、その自由端部をループ状に折り返して縫い付けたループ部24をそれぞれ設けている。
肩ベルト23のループ部24は、図１５に示すように、雄部材30の棒状の第２のベルト固定部100に通し、この状態で雄部材30を雌部材40に連結する。
雄部材30と雌部材40とを連結すると、第２のベルト固定部100のストッパー101が、雌部材40に接近して対向することから、肩ベルト23のループ部24は第２のベルト固定部100から抜けなくなる。
On the other hand, as shown in FIG. 16, the left and right shoulder belts 23 are respectively provided with loop portions 24 in which the free end portions are folded and sewn.
As shown in FIG. 15, the loop portion 24 of the shoulder belt 23 passes through the rod-shaped second belt fixing portion 100 of the male member 30, and connects the male member 30 to the female member 40 in this state.
When the male member 30 and the female member 40 are connected, the stopper 101 of the second belt fixing portion 100 approaches and opposes the female member 40, so that the loop portion 24 of the shoulder belt 23 is the second belt fixing portion. Can't get out of 100.
一方、肩ベルト23を取り外す際には、雄部材30と雌部材40との連結状態を解除すれば良く、ストッパー101を潜らせながら、棒状の第２のベルト固定部100からループ部24を抜き取ることで、肩ベルト23を雄部材30から取り外すことが可能となる。
なお、第２のベルト固定部100を、左右の雄部材30に設けたが、これに限定されず、雌部材40に２個設けても良いし、或いは雄部材30と雌部材40との両方に設けても良い。
（第３の実施の形態の一例）
つぎに、図２０〜２１を用いて、本発明の第３の実施の形態の一例について説明する。
On the other hand, when removing the shoulder belt 23, the connection state between the male member 30 and the female member 40 may be released, and the loop portion 24 is removed from the rod-shaped second belt fixing portion 100 while the stopper 101 is hidden. Thus, the shoulder belt 23 can be detached from the male member 30.
In addition, although the 2nd belt fixing | fixed part 100 was provided in the male member 30 on either side, it is not limited to this, You may provide two in the female member 40, or both the male member 30 and the female member 40 May be provided.
(Example of third embodiment)
Next, an example of the third embodiment of the present invention will be described with reference to FIGS.
本実施の形態は、雄部材30に、図２０〜２１に示すように、リング状の第２のベルト固定部110をそれぞれ設けたものである。
本実施の形態によれば、図１４〜１９を用いて先に説明した第２の実施の形態ものと同様に、５点式シートベルトに使用することができる。
また、本実施の形態によれば、第２の実施の形態のものと比較して、雄部材30単独で肩ベルト23を保持できるという利点がある。なお、第２の実施の形態のものは、図１５に示すように、第２のベルト固定部100は、Ｌ字状に屈曲した棒状に形成され、雄部材30を雌部材40に連結することで、肩ベルト23を抜けないように保持するものである。このため、第２の実施の形態の第２のベルト固定部100は、本第３の実施の形態のリング状の第２のベルト固定部110と比較して、肩ベルト23を容易に取り外すことができるという利点がある。
（第４の実施の形態の一例）
つぎに、図２２〜２３を用いて、本発明の第４の実施の形態の一例について説明する。
In this embodiment, the male member 30 is provided with a ring-shaped second belt fixing portion 110 as shown in FIGS.
According to this embodiment, it can be used for a five-point seat belt as in the second embodiment described above with reference to FIGS.
Further, according to the present embodiment, there is an advantage that the shoulder belt 23 can be held by the male member 30 alone, as compared with the second embodiment. In the second embodiment, as shown in FIG. 15, the second belt fixing portion 100 is formed in a bar shape bent in an L shape, and connects the male member 30 to the female member 40. Thus, the shoulder belt 23 is held so as not to come off. Therefore, the second belt fixing portion 100 of the second embodiment can easily remove the shoulder belt 23 as compared with the ring-shaped second belt fixing portion 110 of the third embodiment. There is an advantage that can be.
