添付図面を参照して本発明の要旨を説明する。
【０００７】
ロープやワイヤーなどの吊部材１に連結される吊具本体２に被吊部材３の表裏位置に挟み込み状態で配設される第一構成部４ａと第二構成部４ｂから成る対向部４を設け、この第一構成部４ａと第二構成部４ｂ夫々に設けた係止棒体嵌挿孔７に嵌挿されて架設状態となる係止棒体６を被吊部材３に設けた孔３ａに嵌挿させることで、吊具本体２と被吊部材３とを着脱自在に連結するように構成した吊具であって、前記第一構成部４ａに設けた係止棒体嵌挿孔７内に突起 15 が突出され、この突起 15 は、係止棒体６の周面長さ方向に形成された凹溝６ｂに係止して、該係止棒体６の係止棒体嵌挿孔７での嵌挿をガイドするとともに、該係止棒体６の係止棒体嵌挿孔７から抜けるのを防止するように構成され、前記第二構成部４ｂに設けた係止棒体嵌挿孔７内に孔壁面７ａ側から中央へ向けて突出付勢された突体８を突没動自在に設け、この突出付勢された突体８が嵌入係止する係止凹部９を前記係止棒体６の周面全体に囲繞状態に設けず周面の一部分に設けて、係止棒体嵌挿孔７に係止棒体６を嵌挿させた際、係止棒体６に押し込まれて突出付勢に抗して没動した後、係止棒体６に設けた係止凹部９に復帰突出動により嵌入係止して前記係止棒体６の抜け移動を阻止するように前記突体８は構成されていることを特徴とする吊具に係るものである。
【０００８】
また、前記吊具本体２に被吊部材３の縁部を挿入する挿入溝５を形成し、この挿入溝５を形成する対向部位を前記対向部４とし、この挿入溝５に被吊部材３を挿入した際、被吊部材３に設けた孔３ａと合致して前記係止棒体６を嵌挿し得る係止棒体嵌挿孔７を前記対向部４に設け、この係止棒体嵌挿孔７に孔壁面７ａ側から中央へ向けて突出付勢された突体８を突没動自在に設け、この突出付勢された突体８が嵌入係止する係止凹部９を前記係止棒体６の周面に設けて、係止棒体嵌挿孔７に係止棒体６を嵌挿させた際、係止棒体６に押し込まれて突出付勢に抗して没動した後、係止棒体６に設けた係止凹部９と合致した位置で復帰突出動により嵌入係止して前記係止棒体６の抜け移動を阻止するように前記突体８を構成したことを特徴とする請求項１記載の吊具に係るものである。
【０００９】
また、前記突体８は前記対向部４の所定位置に付勢部材10の付勢に抗して回動自在となるように設けられており、係止棒体嵌挿孔７に係止棒体６を嵌挿させた際、係止棒体６に押し込まれて付勢に抗して回動した後、係止棒体６に設けた係止凹部９に復帰回動により嵌入係止して前記係止棒体６の抜け移動を阻止するように前記突体８を構成したことを特徴とする請求項１記載の吊具に係るものである。
【００１０】
また、前記突体８を付勢に抗して移動させ係止棒体６との係止状態を解除操作し得る係止解除操作部11を前記突体８に設けたことを特徴とする請求項１〜３のいずれか１項に記載の吊具に係るものである。
【００１１】
【発明の実施の形態】
好適と考える本発明の実施の形態（発明をどのように実施するか）を、図面に基づいてその作用効果を示して簡単に説明する。
【００１２】
本発明は、被吊部材３の吊り上げに際し、吊具本体２の対向部４を被吊部材３の表裏位置に挟み込み状態で配設し、この状態で対向部４に嵌挿されて架設状態となる係止棒体６を被吊部材３に設けた孔３ａに嵌挿して、吊具本体２と被吊部材３とを連結する。
【００１３】
この際、対向部４に設けた係止棒体嵌挿孔７に係止棒体６を嵌挿させると、係止棒体嵌挿孔７内に設けられた突体８が、係止棒体６に押し込まれて突出付勢に抗して没動した後、係止棒体６に設けた係止凹部９に復帰突出動により嵌入係止することになり、よって、係止棒体嵌挿孔７からの係止棒体６の抜け止め作用が発揮される。
【００１４】
従って、係止棒体６の抜け止めが係止棒体嵌挿孔７へ嵌挿する一連の動作の中で行われることになり、例えば嵌挿させた係止棒体６の先端部にナットを止着するような従来から提案される吊具に比し、この吊具本体２と被吊部材３との連結が簡易且つ迅速に行えることになり、このことから吊り上げ作業の作業効率を飛躍的に向上し得ることになる。
【００１５】
【実施例】
図面は本発明の一実施例を図示したものであり、以下に説明する。
【００１６】
符号１はクレーンに連設されるロープやワイヤーなどの吊部材、３は鋼板やＨ鋼などの孔３ａが形成された資材（鋼材）としての被吊部材である。
【００１７】
本実施例は、吊部材１に連結される吊具本体２に被吊部材３の表裏位置に挟み込み状態で配設される対向部４を設け、この対向部４に嵌挿されて架設状態となる係止棒体６を被吊部材３に設けた孔３ａに嵌挿させることで、吊具本体２と被吊部材３とを着脱自在に連結するように構成したものである。
【００１８】
以下、本実施例に係る構成各部について詳細な説明をする。
【００１９】
吊具本体２は、図１，２に図示したように適宜な金属製の部材をコ字状に形成したものであり、その基端部には吊部材１を連結する連結孔２ａが設けられている。
【００２０】
また、吊具本体２は、その先端で開口する凹溝を被吊部材３の縁部を挿入し得る挿入溝５としており、この挿入溝５を形成する対向部位（第一構成部４ａ及び第二構成部４ｂ）は被吊部材３の表裏位置に挟み込み状態で配設し得る対向部４として構成されている。
【００２１】
また、この対向部４を構成する第一構成部４ａ及び第二構成部４ｂ夫々の先端側対向位置には、後述する係止棒体６を嵌挿し得る係止棒体嵌挿孔７が貫通形成されている。
【００２２】
この係止棒体嵌挿孔７は、図１，２に図示したように夫々係止棒体６を嵌挿し得る径に設定されており、第二構成部４ｂに設けられた係止棒体嵌挿孔７には突体８が設けられている。
【００２３】
この突体８は、図２，４に図示したように適宜な金属製の部材を形成したものであり、第二構成部４ｂの係止棒体嵌挿孔７に形成された空間12内に枢着され、この空間12内に設けられた回動規制体13に当接する位置まで回動自在に設けられている。
【００２４】
また、突体８は、その上部に板状の係止部８ａが突出形成され、この係止部８ａは、突体８が回動規制体13に当接して回動規制された状態では、係止棒体嵌挿孔７内への突出量（孔壁面７ａ側から中央方向への突出量）が最大となり、そして、突体８を図２中矢印ａ方向に回動させると、係止棒体嵌挿孔７の孔壁面７ａと略面一状態若しくは没入状態となるように構成されている。
【００２５】
この係止部８ａの突出量は、係止棒体嵌挿孔７に嵌挿した係止棒体６に設けられる係止凹部９に嵌入係止して該係止棒体６の抜けを阻止し得る突出量に設定されている。
【００２６】
また、この係止部８ａは、その先端係止面が湾曲状に形成されており、これは凹湾曲状に形成される係止凹部９に円滑に嵌入係止させるための構成である。
【００２７】
また、突体８は、その枢着部14に発条10（付勢部材）が付設され、この発条10により突体８は回動規制体13へ当接する方向へ回動付勢されている。従って、突体８は、常時その係止部８ａが係止棒体嵌挿孔７の孔壁面７ａから突出状態となるように付勢されており、係止部８ａを係止棒体嵌挿孔７の孔壁面７ａから没入状態とする際には発条10に抗して突体８を回動させることになる。
【００２８】
また、突体８は、その下端部に突部８ｂが設けられ、この突部８ｂは、収納空間12の下方から指をかけて発条10に抗して突体８を回動させることができ、係止棒体６への突体８の係止状態を解除する係止解除操作部11として構成されている。尚、本実施例では、第二構成部４ｂの係止棒体嵌挿孔７にのみ突体８を設けているが、第一構成部４ａのみに設けても、第一構成部４ａ及び第二構成部４ｂ双方に設けるようにしても良い。
【００２９】
また、第一構成部４ａは、図２，３に図示したようにその係止棒体嵌挿孔７の内面に突起15が突出形成されており、この突起15は、係止棒体６に形成された凹溝６ｂに係止して該係止棒体６の挿入する際のガイドとなり、確実に係止凹部９を突体８に係止される位置に配置せしめる為のものである。
【００３０】
また、突起15は、係止棒体６が係止棒体嵌挿孔７から抜けるのを防止する抜け止め機能をも発揮する。これは、係止棒体６が係止棒体嵌挿孔７から抜ける構造であると作業現場において紛失してしまうことがあり、また、高所にて抜いた係止棒体６を落としてしまうと非常に危険であり、これらの問題を解消することに貢献する（従来のボルト・ナット構造では前述した問題が生じていた。）。
【００３１】
係止棒体６は、図２，４に図示したように適宜な金属製の部材を形成したものであり、一端部に係止頭部６ａを有し、吊具本体２の係止棒体嵌挿孔７に嵌挿し得る程度の径に設定され、且つ、この係止棒体嵌挿孔７に嵌挿させた際、第一構成部４ａ及び第二構成部４ｂ間に架設される程度の長さに設定されている。
【００３２】
また、係止棒体６は、その他端部寄りの周面の一部分に係止凹部９が凹湾曲状に形成されている。
【００３３】
この係止凹部９は、係止棒体６を係止棒体嵌挿孔７に嵌挿させた際（係止頭部６ａが第一構成部４の外面に当接した際）、係止棒体嵌挿孔７に設けた突体８の近傍に配設される位置に設けられ、該突体８が嵌入係止し得るように構成されている。
【００３４】
また、係止棒体６は、その周面長さ方向に凹溝６ｂが形成されており、この凹溝６ｂは、係止棒体６を係止棒体嵌挿孔７に嵌挿させた際、第一構成部４ａに設けた突起15にガイドされて係止棒体６が良好に嵌挿されるようにするためのものであり、係止棒体６の嵌挿する方向を決めることで確実に係止凹部９を突体８の近傍位置（嵌入係止される位置）に配設し得るように構成されている。
【００３５】
これは、係止棒体６における係止棒体嵌挿孔７内での回動（軸回動）を防止することで安定的な係止棒体６の止着に貢献するとともに、突体８が係止する係止凹部９を係止棒体６の周面全体に囲繞状態で設けるのではなく、周面の一部分、即ち、係止棒体６を抜け止めとするに十分な最低限の部分だけ係止棒体６に凹部を設けることで、該係止棒体６に径小の部分を設けても係止棒としての強度の低下を生じさせないことに貢献している。
【００３６】
また、係止棒体６は、その下端面が湾曲面に形成しており、これは、係止棒体嵌挿孔７に嵌挿させた際、突体８を円滑に押し込み回動させるための構成である。
【００３７】
以上の構成からなる本実施例に係る吊具の使用方法を説明する。
【００３８】
まず、吊具本体２の挿入溝５に被吊部材３の縁部を挿入し、該被吊部材３の表裏位置に対向部４に係る第一構成部４ａ及び第二構成部４ｂを挟み込み状態で配して、被吊部材３の孔３ａと第一構成部４ａ及び第二構成部４ｂ夫々の係止棒体嵌挿孔７とを合致させる。
【００３９】
続いて、吊具本体２の上方（第一構成部４ａ側）から第一構成部４ａに係る係止棒体嵌挿孔７、被吊部材３の孔３ａ、第二構成部４ｂに係る係止棒体嵌挿孔７の順に係止棒体６を嵌挿させると、係止棒体６の先端部が突体８を押し込むことになり、突体８は発条10に抗して没入方向に回動する（図５，６参照）。
【００４０】
続いて、更に係止棒体６を最後まで嵌挿させ、係止凹部９が突体８に近づいた際、発条10により突出付勢される突体８は突出方向へ回動して係止凹部９に嵌入係止し、係止棒体６は抜け止め状態となり吊具本体２と被吊部材３との連結が完了する（図７参照）。この係止凹部９に対する突体８の係止を解除する際には、突体８の係止解除操作部11（突部８ｂ）を逆方向（図８中矢印ａ方向）へ回動させれば良い。
【００４１】
その後、常法に従い、吊部材１をクレーンなどの重機で吊り上げることになる（図９は横吊り状態、図１０は縦吊り状態を図示している。）。
【００４２】
本実施例は上述のように構成したから、係止棒体６の抜け止めが係止棒体嵌挿孔７へ嵌挿する一連の動作の中でワンタッチで行われることになり、例えば嵌挿させた係止棒体６の先端部にナットを止着するような従来から提案される吊具に比し、この吊具本体２と被吊部材３との連結が簡易且つ迅速に行えることになり、このことから吊り上げ作業の作業効率をも飛躍的に向上し得ることになる。
【００４３】
また、本実施例は、突体８を回動させて係止棒体嵌挿孔７内で突没動する構造を採用したから、係止棒体６の良好な嵌挿係止及び抜け止めが達成される。
【００４４】
即ち、突体８は、係止棒体嵌挿孔７へ係止棒体６を嵌挿させた際には、この嵌挿に従って（係止棒体６に押し込まれて）回動して没動することになり円滑に嵌入係止が達成され、一方、係止棒体６に抜き方向へ力が働いた際には、突体８には突出方向への力が作用することになる為、突体８が没動することは一切なく確実に抜け止めが達成されることになる。
【００４５】
また、本実施例は、突体８を付勢に抗して移動させ係止棒体６との係止状態を解除操作し得る係止解除操作部11を突体８に設けたから、吊具本体２と被吊部材３との連結の解除が簡易且つ迅速に行えることになる。
【００４６】
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。
【００４７】
【発明の効果】
本発明は上述のように構成したから、係止棒体の抜け止めが係止棒体嵌挿孔へ嵌挿する一連の動作の中で行われることになり、この吊具本体と被吊部材との連結が簡易且つ迅速に行えることになり、このことから吊り上げ作業の作業効率を飛躍的に向上し得ることになるなど極めて商品価値の高い画期的な吊具となる。
【００４８】
また、請求項２記載の発明においては、前記請求項１記載の発明の作用効果に加え、確実に吊具本体と被吊部材との連結が達成されるなど極めて商品価値の高い画期的な吊具となる。
【００４９】
また、請求項３記載の発明においては、前記請求項１，２記載の発明の作用効果に加え、突体を回動させて係止棒体嵌挿孔内で突没動する構造を採用したから、係止棒体嵌挿孔に対する係止棒体の良好な嵌挿係止及び抜け止めが達成されるなど極めて商品価値の高い画期的な吊具となる。
【００５０】
また、請求項４記載の発明においては、前記請求項１〜３記載の発明の作用効果に加え、係止解除操作部により吊具本体と被吊部材との連結の解除が簡易且つ迅速に行えることになるなど極めて商品価値の高い画期的な吊具となる。

The projecting body 8 is provided with a sprung 10 (biasing member) at a pivot portion 14, and the projecting body 10 is urged to rotate in a direction in which the projecting body 8 comes into contact with the rotation restricting body 13. Therefore, the projection 8 is always urged so that the locking portion 8a projects from the hole wall surface 7a of the locking rod fitting hole 7, and the locking portion 8a is inserted into the locking rod body. When the body 7 is immersed from the hole wall surface 7a of the hole 7, the projecting body 8 is rotated against the protrusion 10.
[0028]
The projecting body 8 is provided with a projecting part 8b at the lower end thereof. The projecting part 8b can be rotated from below the storage space 12 with a finger against the projecting part 10 by putting a finger. It is configured as an unlocking operation section 11 for unlocking the locking state of the projection 8 with the locking rod 6. In this embodiment, the projection 8 is provided only in the locking rod body insertion hole 7 of the second component 4b. However, the projection 8 may be provided only in the first component 4a. You may make it provide in both two components 4b.
[0029]
As shown in FIGS. 2 and 3, the first component 4 a has a projection 15 protruding from the inner surface of the locking rod insertion hole 7. The projection 15 is formed on the locking rod 6. The locking recess 6 is locked in the formed groove 6b and serves as a guide when the locking rod 6 is inserted, so that the locking recess 9 is securely disposed at a position where the locking recess 9 is locked by the projection 8.
[0030]
The projection 15 also has a function of preventing the locking rod 6 from coming out of the locking rod fitting hole 7. This is because if the locking bar 6 has a structure in which the locking bar 6 comes out of the locking bar fitting insertion hole 7, it may be lost at the work site, and the locking bar 6 pulled out at a high place may be dropped. This is very dangerous and contributes to resolving these problems (the above-mentioned problems have occurred in the conventional bolt / nut structure).
[0031]
The locking rod body 6 is formed by forming an appropriate metal member as shown in FIGS. 2 and 4, has a locking head 6 a at one end, and has a locking rod body of the hanging body 2. The diameter is set to such an extent that it can be inserted into the insertion hole 7, and when it is inserted into the locking rod insertion hole 7, the extent that it is bridged between the first component 4 a and the second component 4 b. Is set to the length.
[0032]
In addition, the locking rod body 6 has a locking concave portion 9 formed in a part of a peripheral surface near the other end in a concavely curved shape.
[0033]
When the locking rod 6 is fitted into the locking rod insertion hole 7 (when the locking head 6a contacts the outer surface of the first component 4), the locking recess 9 is locked. It is provided at a position arranged near the protrusion 8 provided in the rod insertion hole 7, and is configured such that the protrusion 8 can be fitted and locked.
[0034]
The locking rod 6 has a groove 6b formed in the length direction of the peripheral surface thereof. The groove 6b allows the locking rod 6 to be inserted into the locking rod fitting hole 7. In this case, the locking rod 6 is guided by the projection 15 provided on the first component portion 4a so that the locking rod 6 can be properly inserted. The direction in which the locking rod 6 is inserted is determined. It is configured such that the locking concave portion 9 can be reliably disposed at a position near the protruding body 8 (a position where it is fitted and locked).
[0035]
This contributes to stable fastening of the locking rod body 6 by preventing the rotation (axial rotation) of the locking rod body 6 in the locking rod body insertion hole 7, and contributes to the protrusion. The locking recess 9 for locking the locking rod 8 is not provided on the entire peripheral surface of the locking rod body 6 in a surrounding state, but is provided on a part of the peripheral surface, that is, the minimum minimum sufficient to prevent the locking rod body 6 from coming off. The provision of the concave portion in the locking rod body 6 only at the portion (3) contributes to preventing the strength of the locking rod from being reduced even if a small diameter portion is provided in the locking rod body 6.
[0036]
The lower end surface of the locking rod body 6 is formed into a curved surface. This is because when the locking rod body 6 is inserted into the locking rod body insertion hole 7, the protrusion 8 is smoothly pushed and rotated. It is a structure of.
[0037]
