Description

【０００１】
【発明の属する技術分野】
本発明は、例えばヘルメットなどの顎紐を係脱可能とする連結具に関するものである。
【０００２】
【従来の技術】
図５（ａ），（ｂ）は従来の連結具の一例を示す平面図である。
図５（ａ），（ｂ）に示すように、従来の連結具は、本体１００と、挿脱体１０８とを備えている。
【０００３】
本体１００は、上下板１０１の間に各支軸１０２を中心にして揺動可能に支持された一対の係合部１０３を備えている。各係合部１０３は、上下板１０１の各側部にて突出する操作突起１０３ａをそれぞれ有している。また、各係合部１０３は、一方の揺動端１０３ｂに鉤状の係合爪１０４を有し、この係合爪１０４の鉤状の先端をそれぞれ対向させている。また、各係合部１０３は、他方の揺動端１０３ｃ側の対向する部位にバネ部材１０５が介在されて、互いに離間するように常に付勢されている。即ち、係合部１０３の一方の揺動端１０３ｂは、バネ部材１０５により、互いに係合爪１０４を近接するように常に付勢される。また、各係合部１０３の他方の揺動端１０３ｃは、上下板１０１の間に設けられた各規制部材１０６によって離間した範囲が規制されている。また、上下板１０１における係合部１０３の他方の揺動端１０３ｃ側には、紐類（不図示）などの一方が取り付けられる環状の挿通部１０７が設けられている。
【０００４】
挿脱体１０８は、上記各係合部１０３の各係合爪１０４の間に挿通されて係合する係合片１０９を有している。また、挿脱体１０８の係合爪片１０９と相反する側には、紐類（不図示）などの他方が取り付けられる環状の挿通部１１０が設けられている。
【０００５】
上記従来の連結具は、図５（ａ）に示すように、挿脱体１０８の係合爪片１０９を本体１００の上下板１０１の間にて各係合部１０３の係合爪１０４の間に挿通することで、バネ部材１０５によって互いに近接する係合爪１０４に係合爪片１０９が係合する。これにより、本体１００に挿脱体１０８が連結され、互いの挿通部１０７，１１０に取り付けられた一方および他方の紐類が連結される。
【０００６】
また、図５（ｂ）に示すように、各操作突起１０３ａを内方向に押すことにより、各係合部１０３の係合爪１０４がバネ部材１０５の付勢力に抗して離間する。これにより、係合爪１０４と係合爪片１０９の係合が解除され、挿脱体１０８が本体１００に対して自由となる。そして、各操作突起１０３ａを内方向に押したままの状態で、本体１００から挿脱体１０８を引き抜くことにより、一方および他方の紐類が分離される。
【０００７】
【発明が解決しようとする課題】
しかしながら、上述した従来の連結具では、図５（ｂ）に示すように、係合爪１０４と係合爪片１０９の係合が解除されたとき、挿脱体１０８が本体１００に対して自由となるが、挿脱体１０８を本体１００から引き抜かなければ分離することができない。即ち、一方の手で各操作突起１０３ａを押しながら、他方の手で挿脱体１０８を本体１００から引き抜くように、両手での操作が必要になってしまう。
【０００８】
また、使用者は、操作突起１０３ａを押すだけで本体１００からの挿脱体１０８の分離が行われていると認識してしまい、分離したはずなのに分離されていない煩わしさを感じてしまう。特に、従来の連結具がヘルメットの顎紐を連結する場合では、手袋を装着した状態で連結具の操作を行うことが多く、且つ、見えにくい顎部に連結具があるために、非常に煩わしく感じてしまう。
【０００９】
そこで本発明は、上記課題を解消するために、両手を用いることなく一操作で確実に分離することができる連結具を提供することを目的としている。
【００１０】
【課題を解決するための手段】
上記目的を達成するため本発明による請求項１記載の連結具は、
収容部（５）内にて互いに対向する係合爪（８，８）を接離可能に揺動支持し、前記各係合爪（８，８）を離間させるように前記収容部（５）外から押動操作を可能とされた本体（１）と、
前記収容部（５）に挿通されて、前記各係合爪（８，８）の間で係合する係合爪片（１６）を有した挿脱体（２）と、
第一の捩じり部（１０ａ）を介してその両側に延出する両腕部（１０ｂ，１０ｂ）の先端に円環部（１０ｄ，１０ｄ）を有し、両腕部（１０ｂ，１０ｂ）の中途部分に第二の捩じり部（１０ｃ，１０ｃ）を有してなり、前記本体（１）の収容部（５）内に設けられて、前記第一の捩じり部（１０ａ）による前記両腕部（１０ｂ，１０ｂ）の広角付勢力によって前記係合爪（８，８）同士を近接するように付勢するバネ部材（１０）と、
前記本体（１）の収容部（５）内に固定して設けられた支持部（１３）であって、平坦面（１３ａ）の中央に突起（１３ｂ）を有してなり、前記バネ部材（１０）の両腕部（１０ｂ，１０ｂ）の前記第二の捩じり部（１０ｃ，１０ｃ）から延出される各先端の円環部（１０ｄ，１０ｄ）を突起（１３ｂ）を挟むようにして平坦面（１３ａ）に当接支持する支持部（１３）と、
を備え、前記第一の捩じり部（１０ａ）による前記両腕部（１０ｂ，１０ｂ）の広角付勢力に抗した押動操作によって離間した前記各係合爪（８，８）から前記係合爪片（１６）が外れた際、前記バネ部材（１０）の先端円環部（１０ｂ，１０ｂ）を前記支持部（１３）に支持させつつ、前記第二の捩じり部（１０ｃ，１０ｃ）が対向内方に押し圧されることで移動した前記第一の捩じり部（１０ａ）によって、前記係合爪片（１６）が前記収容部（５）外に押し出されることを特徴とする。
【００１１】
前記支持部の前記収容部外の部分には、紐類が取り付けられる環状の挿通部が形成されている。
【００１２】
【発明の実施の形態】
以下、本発明の実施の形態を図面を参照して具体的に説明する。
図１は本発明による連結具の一例を示す分解斜視図、図２は前記連結具の使用状態を示す斜視図である。
図１および図２に示すように、連結具は、本体１と挿脱体２からなる。
【００１３】
本体１は、上下板３，４の間に収容部５をなす空間を形成している。収容部５内には、各支軸６を中心にして揺動可能に支持された一対の係合部７を備えている。各支軸６は、本実施の形態では上下板３，４を一体とするリベットなどの固定部材からなり、上下板３，４の各固定穴３ａ，４ａを挿通する間に係合部７の軸穴７ａに遊挿する。各係合部７は、支軸６を介した一方の揺動端７ｂに鉤状の係合爪８を有している。各係合爪８は、鉤状の先端をそれぞれ対向している。また、各係合部７の支軸６を介した他方の揺動端７ｃ側の側部には、上下板３，４（収容部５）から突出する操作突起９が設けられている。
【００１４】
収容部５内であって、各係合部７の他方の揺動端７ｃの間には、バネ部材１０が設けられている。バネ部材１０は、捩じりコイルバネの複合体からなり、第一の捩じり部１０ａを介して延出する両腕部１０ｂを有している。両腕部１０ｂの中途部分には、第二の捩じり部１０ｃが設けられている。また、両腕部１０ｂの先端には、円環部１０ｄが形成されている。
【００１５】
バネ部材１０は、各係合部７の間にて、第一の捩じり部１０ａによる両腕部１０ｂの広角付勢力によって各係合部７の他方の揺動端７ｃを側方に押し広げて各係合爪８同士を近接するように付勢する。なお、上下板３，４には、バネ部材１０によって押し広げられた係合部７の他方の揺動端７ｃに当接して、その揺動範囲を規制する規制部材１１が設けられている。また、第一の捩じり部１０ａによる両腕部１０ｂの広角付勢力に抗して各操作突起９を押動操作することにより、各係合爪８が離間する。
【００１６】
また、上下板３，４には、係合部７の他方の揺動端７ｃ側には、図２に示すように紐類Ａの一方が取り付けられる環状の挿通部１２が固定されている。この挿通部１２は、一部が収容部５内に臨み、バネ部材１０の両腕部１０ｂの各先端（円環部１０ｄ）が当接支持される支持部１３をなす。この支持部１３は、係合部７に向く平坦面１３ａの中央に突起１３ｂを有してなる。バネ部材１０の両腕部１０ｂの各先端（円環部１０ｄ）は、平坦面１３ａに当接するとともに、突起１３ｂを挟むようにして配される。なお、挿通部１２は、上下板３，４を一体とするリベットなどの固定部材１４が、上下板３，４の各固定穴３ｂ，４ｂを挿通する間に挿通部１２の固定穴１２ａに挿通して固定される。
【００１７】
挿脱体２は、係合爪片１６を有している。係合爪片１６は、上記本体１の収容部５に挿通されて各係合部７の各係合爪８の間に係合するように、両側に鉤状の先端を延出した略矢印形状をなしている。また、挿脱体２の係合爪片１６と相反する側には、図２に示すように紐類Ａの他方が取り付けられる環状の挿通部１７が設けられている。この挿通部１７には、紐類Ａの他端を架け回して長さ調整可能にする係止部材１８が配されている。
【００１８】
上記連結具の動作を説明する。
図３（ａ）（ｂ）は連結具の動作を示す平面図である。
この図３（ａ）（ｂ）では、上板３を外した状態としている。
【００１９】
まず、本体１に対して挿脱体２を挿通する。挿脱体２を本体１の収容部５に挿通すると、係合爪片１６が各係合爪８を押し広げるようにして各係合爪８の間に挿通され、図３（ａ）に示すように係合爪片１６と各係合爪８が互いに係合する。各係合爪８は、バネ部材１０によって近接方向に付勢されているので、係合爪片１６が各係合爪８との係合から外れることがない。これにより、図２で示す紐類Ａの一方と他方が連結される。
【００２０】
なお、バネ部材１０は、第一の捩じり部１０ａによる両腕部１０ｂの広角付勢力により各係合部７の他方の端部７ｃを側方に広げる。これにより、支軸６を介して各係合爪８が近接方向に付勢される。また、バネ部材１０は、第二の捩じり部１０ｃによる広角付勢力により、両腕部１０ｂの先端の円環部１０ｄが支持部１３の平坦面１３ａに当接しつつ突起１３ｂを挟んだ状態となっている。
【００２１】
次に、本体１から挿脱体２を外す。各係合部７の操作突起９を内方に押動操作すると、バネ部材１０の付勢力に抗して各係合爪８が離間し各係合爪８と係合爪片１６の係合が解かれる。バネ部材１０は、図３（ｂ）に示すように、操作突起９の押動操作で近接方向に揺動する各係合部７の他方の端部７ｃ側によって押し潰されることとなる。この際、バネ部材１０は、第一の捩じり部１０ａが係合爪片１６の先端に当接するとともに、両腕部１０ｂの先端の円環部１０ｄが支持部１３の平坦面１３ａに当接しつつ突起１３ｂを挟んでいることにより、第二の捩じり部１０ｃが対向内方に押圧されて広角し、第一の捩じり部１０ａを各係合爪８の間に移動させる。そして、移動した第一の捩じり部１０ａは、各係合爪８との係合が解かれた係合爪片１６の先端を押す。これにより、係合爪片１６が収容部５外に押し出されて本体１から挿脱体２が外れることとなる。
【００２２】
したがって、このように構成された連結具では、各操作突起９を内方に押動操作することにより、本体１側の各係合爪８と、挿脱体２側の係合爪片１６との係合が解かれる。これと同時に、バネ部材１０によって係合爪片１６が本体１から押し出されて本体１から挿脱体２が外れる。このように、上述した連結具は、両手を用いることなく操作突起９の一操作で確実に分離することが可能となる。
【００２３】
また、上述した連結具では、第一捩じり部１０ａと第二捩じり部１０ｃを有した複合体のバネ部材１０を備えている。このバネ部材１０は、捩じりコイルバネの構成であるため、本体１の小型化（薄型）を図ることが可能である。
【００２４】
ところで、上述した実施の形態では、バネ部材１０が、第一捩じり部１０ａと第二捩じり部１０ｃを有した複合体として構成されている。これに限らず、別体のバネ部材を用いた構成も考えられる。
【００２５】
図４（ａ）（ｂ）は連結具の参考例を示す平面図である。
なお、図４で示す参考例の連結具は、上述した図１乃至図３（ａ）（ｂ）で示す連結具に対し、本体１および挿脱体２の構成は同様であり、バネ部材２０のみ構成が異なる。ゆえに、他の連結具に以下の説明において、上述した連結具と同一箇所には同一の符号を付して説明を省略する。
【００２６】
バネ部材２０は、圧縮コイルバネからなる主バネ２０ａと副バネ２０ｂからなる。主バネ２０ａは、収容部５内にて、各係合部７の他方の揺動端７ｃの間に介在されている。これにより、各係合部７の係合爪８が常に近接方向に付勢される。副バネ２０ｂは、収容部５内にて、各係合部７の間にて挿脱体２の挿脱方向に付勢力を得るようにして設けられている。この副バネ２０ｂは、上下板３，４に設けられた溝部２１内に配されている。また、溝部２１内にて、副バネ２０ｂの係止爪８側に向く端部には、押出部材２２が設けられている。押出部材２２は必須ではない。
【００２７】
このように構成された他の結合具の動作を説明する。
まず、本体１に対して挿脱体２を挿通する。挿脱体２を本体１の収容部５に挿通すると、係合爪片１６が各係合爪８を押し広げるようにして各係合爪８の間に挿通され、図４（ａ）に示すように係合爪片１６と各係合爪８が互いに係合する。各係合爪８は、主バネ２０ａによって近接方向に付勢されているので、係合爪片１６が各係合爪８との係合から外れることがない。これにより、紐類Ａの一方と他方が連結される（図２参照）。
【００２８】
次に、本体１から挿脱体２を外す。各係合部７の操作突起９を内方に押動操作すると、主バネ２０ａの付勢力に抗して各係合爪８が離間し各係合爪８と係合爪片１６の係合が解かれる。この際、副バネ２０ｂが、各係合爪８との係合が解かれた係合爪片１６の先端を押す。これにより、係合爪片１６が収容部５外に押し出されて本体１から挿脱体２が外れることとなる。
【００２９】
したがって、このように構成された連結具では、各操作突起９を内方に押動操作することにより、本体１側の各係合爪８と、挿脱体２側の係合爪片１６との係合が解かれる。これと同時に、バネ部材２０（２０ｂ）によって係合爪片１６が本体１から押し出されて本体１から挿脱体２が外れる。このように、上述した連結具は、両手を用いることなく操作突起９の一操作で確実に分離することが可能となる。
【００３０】
【発明の効果】
以上説明したように本発明による連結具は、各係合爪を離間させるように押動操作することにより、各係合爪と係合爪片との係合が解かれる。これと同時に、バネ部材によって係合爪片が本体から押し出されて本体から挿脱体が外れる。これにより、本体と挿脱体とを両手を用いることなく押動操作の一操作で確実に分離することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a connector that allows a chin strap such as a helmet to be engaged and disengaged.
[0002]
[Prior art]
5A and 5B are plan views showing an example of a conventional connector.
As shown in FIGS. 5A and 5B, the conventional connector includes a main body 100 and an insertion / removal body 108.
[0003]
The main body 100 includes a pair of engaging portions 103 supported so as to be swingable about the respective support shafts 102 between the upper and lower plates 101. Each engagement portion 103 has an operation protrusion 103 a that protrudes from each side portion of the upper and lower plates 101. Each engaging portion 103 has a hook-like engaging claw 104 at one swinging end 103b, and the hook-like tips of the engaging claws 104 are opposed to each other. In addition, each engaging portion 103 is always urged so as to be separated from each other with a spring member 105 interposed in an opposing portion on the other swing end 103c side. That is, one swinging end 103 b of the engaging portion 103 is always urged by the spring member 105 so that the engaging claws 104 are close to each other. Further, the other swinging end 103 c of each engaging portion 103 is restricted in a range separated by each restricting member 106 provided between the upper and lower plates 101. An annular insertion portion 107 to which one of strings (not shown) or the like is attached is provided on the other swing end 103c side of the engagement portion 103 in the upper and lower plates 101.
[0004]
The insertion / removal body 108 has an engagement piece 109 that is inserted and engaged between the engagement claws 104 of the engagement portions 103. Further, an annular insertion portion 110 to which the other such as strings (not shown) is attached is provided on the side opposite to the engaging claw piece 109 of the insertion / removal body 108.
[0005]
As shown in FIG. 5 (a), the conventional connecting tool is configured such that the engaging claw piece 109 of the inserting / removing body 108 is interposed between the upper and lower plates 101 of the main body 100 and between the engaging claws 104 of the engaging portions 103. The engaging claw piece 109 engages with the engaging claw 104 that is close to each other by the spring member 105. Thereby, the insertion / removal body 108 is connected to the main body 100, and one and the other strings attached to the insertion portions 107 and 110 are connected.
[0006]
Further, as shown in FIG. 5B, by pushing the operation protrusions 103 a inward, the engagement claws 104 of the engagement portions 103 are separated from each other against the urging force of the spring member 105. Thereby, the engagement between the engagement claw 104 and the engagement claw piece 109 is released, and the insertion / removal body 108 becomes free with respect to the main body 100. Then, while the operation protrusions 103a are pressed inward, the one and the other strings are separated by pulling out the insertion / removal body 108 from the main body 100.
[0007]
[Problems to be solved by the invention]
However, in the conventional connector described above, as shown in FIG. 5 (b), when the engagement claw 104 and the engagement claw piece 109 are disengaged, the insertion / removal body 108 is free from the main body 100. However, it cannot be separated unless the insertion / removal body 108 is pulled out from the main body 100. That is, it is necessary to operate with both hands so that the insertion protrusion 108 is pulled out from the main body 100 with the other hand while pressing each operation protrusion 103a with one hand.
[0008]
In addition, the user recognizes that the insertion / removal body 108 has been separated from the main body 100 simply by pressing the operation protrusion 103a, and thus feels bothered but not separated. In particular, when the conventional connecting tool connects the chin strap of the helmet, the connecting tool is often operated in a state where gloves are worn, and there is a connecting tool in the hard-to-see jaw part, which is very troublesome. I feel it.
[0009]
Accordingly, an object of the present invention is to provide a connector that can be reliably separated by one operation without using both hands in order to solve the above-described problems.
[0010]

Thus, the engaging claw piece 16 and each engaging claw 8 are engaged with each other. Since each engagement claw 8 is urged in the proximity direction by the spring member 10, the engagement claw piece 16 does not come out of engagement with each engagement claw 8. Thereby, one and the other of the string A shown in FIG. 2 are connected.
[0020]
The spring member 10 widens the other end 7c of each engaging portion 7 to the side by the wide-angle biasing force of both arms 10b by the first twisted portion 10a. Thereby, each engaging claw 8 is urged | biased by the proximity | contact direction via the spindle 6. As shown in FIG. Further, the spring member 10 is in a state in which the annular portion 10d at the tips of both arm portions 10b is in contact with the flat surface 13a of the support portion 13 and the protrusion 13b is sandwiched by the wide-angle biasing force by the second torsion portion 10c. It has become.
[0021]
Next, the insertion / removal body 2 is removed from the main body 1. When the operation projection 9 of each engagement portion 7 is pushed inward, each engagement claw 8 is separated against the urging force of the spring member 10 and the engagement claw 8 and the engagement claw piece 16 are engaged. Is solved. As shown in FIG. 3B, the spring member 10 is crushed by the other end 7 c side of each engaging portion 7 that swings in the proximity direction by the pushing operation of the operation protrusion 9. At this time, in the spring member 10, the first twisted portion 10 a comes into contact with the distal end of the engaging claw piece 16, and the annular portion 10 d at the distal ends of both arm portions 10 b contacts the flat surface 13 a of the support portion 13. By sandwiching the projection 13b while being in contact, the second twisted portion 10c is pressed inward and wide-angled, and the first twisted portion 10a is moved between the engaging claws 8. Then, the moved first twisted portion 10a pushes the tip of the engaging claw piece 16 disengaged from each engaging claw 8. As a result, the engaging claw piece 16 is pushed out of the accommodating portion 5 and the insertion / removal body 2 is detached from the main body 1.
[0022]
Therefore, in the coupling tool configured as described above, by operating the operation protrusions 9 inwardly, the engagement claws 8 on the main body 1 side, the engagement claw pieces 16 on the insertion / removal body 2 side, Is disengaged. At the same time, the engaging claw piece 16 is pushed out from the main body 1 by the spring member 10, and the insertion / removal body 2 is detached from the main body 1. As described above, the above-described connector can be reliably separated by one operation of the operation protrusion 9 without using both hands.
[0023]
In addition, the coupling tool described above includes the composite spring member 10 having the first twisted portion 10a and the second twisted portion 10c. Since the spring member 10 has a configuration of a torsion coil spring, the main body 1 can be downsized (thinned).
[0024]
By the way, in embodiment mentioned above, the spring member 10 is comprised as a composite_body | complex which has the 1st twist part 10a and the 2nd twist part 10c. Not only this but the structure using a separate spring member is also considered.
[0025]
4A and 4B are plan views showing a reference example of a connector.
In addition, the connection tool of the reference example shown in FIG. 4 is the same as the connection tool shown in FIG. 1 to FIG. 3A and FIG. Only the configuration is different. Therefore, in the following description, the same reference numerals are assigned to the same portions as the above-described connectors, and description thereof is omitted in the following description.
[0026]
The spring member 20 includes a main spring 20a and a secondary spring 20b that are compression coil springs. The main spring 20a is interposed between the other swinging ends 7c of the engaging portions 7 in the accommodating portion 5. Thereby, the engaging claw 8 of each engaging part 7 is always biased in the proximity direction. The auxiliary spring 20 b is provided in the housing portion 5 so as to obtain a biasing force in the insertion / removal direction of the insertion / removal body 2 between the engagement portions 7. The auxiliary spring 20b is disposed in a groove portion 21 provided in the upper and lower plates 3 and 4. In addition, an extrusion member 22 is provided in the groove portion 21 at an end portion of the auxiliary spring 20b facing the locking claw 8 side. The pushing member 22 is not essential.
[0027]
The operation of the other coupler thus configured will be described.
First, the insertion / removal body 2 is inserted into the main body 1. When the inserting / removing body 2 is inserted into the housing portion 5 of the main body 1, the engaging claw pieces 16 are inserted between the engaging claws 8 so as to push the engaging claws 8 apart, as shown in FIG. Thus, the engaging claw piece 16 and each engaging claw 8 are engaged with each other. Since each engagement claw 8 is urged in the proximity direction by the main spring 20 a, the engagement claw piece 16 does not come out of engagement with each engagement claw 8. Thereby, one side of string A and the other are connected (refer to Drawing 2).
[0028]
Next, the insertion / removal body 2 is removed from the main body 1. When the operation projection 9 of each engagement portion 7 is pushed inward, the engagement claws 8 are separated from each other against the biasing force of the main spring 20a, and the engagement claws 8 and the engagement claw pieces 16 are engaged. Is solved. At this time, the auxiliary spring 20b presses the tip of the engaging claw piece 16 disengaged from each engaging claw 8. As a result, the engaging claw piece 16 is pushed out of the accommodating portion 5 and the insertion / removal body 2 is detached from the main body 1.
[0029]
Therefore, in the coupling tool configured as described above, by operating the operation protrusions 9 inwardly, the engagement claws 8 on the main body 1 side, the engagement claw pieces 16 on the insertion / removal body 2 side, Is disengaged. At the same time, the engaging claw piece 16 is pushed out from the main body 1 by the spring member 20 (20 b), and the insertion / removal body 2 is detached from the main body 1. As described above, the above-described connector can be reliably separated by one operation of the operation protrusion 9 without using both hands.
[0030]
【The invention's effect】
As described above, in the connector according to the present invention, the engagement between each engagement claw and the engagement claw piece is released by performing a push operation so as to separate each engagement claw. At the same time, the engaging claw piece is pushed out of the main body by the spring member, and the insertion / removal member is detached from the main body. Thereby, a main body and an insertion / removal body can be reliably isolate | separated by one operation of pushing operation, without using both hands.
