The abutting portion 23 a of the spring 23 is fitted into the spring receiving recess 30 of the hook body 17, and the abutting portion 23 a of the spring 23 is fitted into the spring receiving recess 30 of the lock member 18. What is necessary is just to fit the edge part of the connecting rod 13 in the base part 19. FIG.

これにより、バネ２３の当接部２３ａがフック本体１７のバネ受け凹部３０に嵌合し、バネ２３の当接部２３ａがロック部材１８のバネ受け凹部３１に嵌合することによって、厚み方向と直交するバネ２３の径方向に、バネ２３が本体基部１９に対して移動するのが規制され、バネ２３の当接部２３ａが、本体基部１９に外嵌した連結杆１３に接当することにより、バネ２３の厚み方向への移動が規制される。
また、保持溝２１の厚み方向の両端開口が、本体基部１９に嵌合した連結杆１３で塞がれ、保持溝２１に収納したバネ２３及びロック部材１８が保持溝２１の厚み方向の開口から不測に抜けなくなる。また、保持溝２１に収納したロック部材１８の挿入基部により、保持溝２１の抜止位置Ａ側の開口が塞がれ、保持溝２１に保持したバネ２３が保持溝２１から抜け脱しなくなる。 As a result, the contact portion 23a of the spring 23 is fitted into the spring receiving recess 30 of the hook body 17, and the contact portion 23a of the spring 23 is fitted into the spring receiving recess 31 of the lock member 18, whereby the thickness direction The movement of the spring 23 relative to the main body base 19 in the radial direction of the orthogonal spring 23 is restricted, and the contact portion 23 a of the spring 23 comes into contact with the connecting rod 13 fitted on the main body base 19. The movement of the spring 23 in the thickness direction is restricted.
Further, both end openings in the thickness direction of the holding groove 21 are blocked by the connecting rods 13 fitted to the main body base 19, and the spring 23 and the lock member 18 housed in the holding groove 21 are opened from the opening in the thickness direction of the holding groove 21. It will not come out unexpectedly. In addition, the insertion base of the lock member 18 housed in the holding groove 21 closes the opening on the retaining position A side of the holding groove 21 so that the spring 23 held in the holding groove 21 does not come out of the holding groove 21.

従って、連結杆１３が外嵌される本体基部１９に、保持溝２１を形成すればよく、従来（特開平１０−２１０５号公報）のように、フック本体１７のフック部２０側に、保持溝２１を形成するためのスペースは不用になり、フック本体１７が極力の小型になると共に、フック本体１７及びロック部材１８の構造が簡単で、部品点数が少なくなり、フック本体１７及びロック部材１８を押出成形材で簡単に製造できるようになる。
また、従来は、フック本体、ロック部材、バネをそれぞれ固定するためにピンなどの部品や加工が必要であったが、本実施の形態では、フック本体１７、ロック部材１８及びバネ２３を互いに嵌め入れるだけで、各部品の位置が決まり、部品点数を減らすことができる。特に、バネ２３は、両端の当接部２３ａが楕円形状になっているので、保持溝２１にバネ２３を嵌め入れるだけでバネ２３の中心位置を決めることができる。 Accordingly, the holding groove 21 may be formed in the main body base portion 19 to which the connecting rod 13 is fitted, and the holding groove is formed on the hook portion 20 side of the hook main body 17 as in the prior art (Japanese Patent Laid-Open No. 10-2105). The space for forming 21 is not required, the hook body 17 becomes as small as possible, the structure of the hook body 17 and the lock member 18 is simple, the number of parts is reduced, and the hook body 17 and the lock member 18 are Easy to manufacture with extruded material.
Conventionally, parts such as pins and processing have been required to fix the hook main body, the lock member, and the spring, but in this embodiment, the hook main body 17, the lock member 18 and the spring 23 are fitted together. By simply inserting, the position of each part is determined, and the number of parts can be reduced. In particular, since the spring 23 has an abutting portion 23a at both ends, the center position of the spring 23 can be determined simply by fitting the spring 23 into the holding groove 21.

また、連結杆１３の端部が垂直に切断されているだけであれば、連結杆１３の端部でロック部材１８が隠れてしまい、ロック部材１８を退避位置Ｂに移動するための操作ができなくなるため、ロック部材１８を操作できるようにするには、ロック部材１８を連結杆１３よりはみ出た状態にしなければならず、部材が余分に必要になり、また、はみ出ているために、引っ掛かったり破損し易くもなるが、本実施の形態の場合、連結杆１３の端部のロック部材１８側を斜めに切断することにより、上記余分な部材が必要になる等の問題を解決して、ロック部材１８を退避位置Ｂに簡単に操作できるようになる。   Further, if the end of the connecting rod 13 is only cut vertically, the lock member 18 is hidden by the end of the connecting rod 13, and an operation for moving the lock member 18 to the retracted position B can be performed. Therefore, in order to be able to operate the lock member 18, the lock member 18 has to be protruded from the connecting rod 13, and an extra member is required. In the case of this embodiment, the lock member 18 side of the end of the connecting rod 13 is cut obliquely to solve the problem that the extra member is required, and the lock The member 18 can be easily operated to the retracted position B.

また、直線的にスライドする棒状のロック部材では、フック本体に嵌め入れるためにロック部材の大きさが制限されてしまい、かつスライド量も大きくできないという欠点があるが、本実施の形態では、保持溝２１は、抜止位置Ａに向けて円弧状に湾曲形成され、ロック部材１８は保持溝２１に対応して円弧状に湾曲形成されているので、ロック部材１８を円弧状にしスライド方向を変化させることができるため、棒状のロック部材１８よりもスライドする距離を大きくすることができるようになる。また、ロック部材１８が回転することによりロックさせる構造では、ロック部材１８を回転させるための軸をピンなどで設ける必要があったが、ロック部材１８自体を円弧状にすることにより、軸がなくても回転させることができるようになり、部品点数を減らすことができるようになる。   In addition, the rod-shaped lock member that slides linearly has the disadvantages that the size of the lock member is limited in order to fit into the hook body, and the sliding amount cannot be increased. The groove 21 is curved and formed in an arc shape toward the retaining position A, and the lock member 18 is formed in an arc shape corresponding to the holding groove 21. Therefore, the lock member 18 is formed in an arc shape and the sliding direction is changed. Therefore, the sliding distance can be made larger than that of the rod-shaped lock member 18. Further, in the structure in which the lock member 18 is locked by rotating, it is necessary to provide a shaft for rotating the lock member 18 with a pin or the like, but there is no shaft by making the lock member 18 arcuate. However, it can be rotated, and the number of parts can be reduced.

なお、前記実施の形態では、フック装置１５は、梯子枠８の２つを連結する第１連結部材（ブレース）９及び第２連結部材（横杆）１０の両端部に設けられ、フック装置１５は、梯子枠８の踏み桟（パイプ材等の軸材）６に嵌脱自在に嵌合されるようになっているが、本発明が適用されるフック装置１５は、このような梯子枠８の２つを連結する連結部材に限定されず、連結杆の両端部又は一端部に設けられて、軸材６に嵌合されて、部材同士を連結するための連結部材であればよい。
また、前記実施の形態では、ロック部材１８を抜止位置Ａに突出するように付勢する弾性体として、コイルバネ２３を保持溝２１に設けているが、コイルバネ２３に代えて、ロック部材１８を抜止位置Ａに突出するように付勢する弾性体として、板バネその他のバネを設けるようにしてもよいし、また、弾性体として、ゴムその他を設けるようにしてもよい。 In the above-described embodiment, the hook device 15 is provided at both ends of the first connecting member (brace) 9 and the second connecting member (recumbent rod) 10 that connect the two ladder frames 8. Is adapted to be detachably fitted to a stepping bar (a shaft member such as a pipe member) 6 of the ladder frame 8, but the hook device 15 to which the present invention is applied has such a ladder frame 8. It is not limited to the connection member which connects these two, What is necessary is just the connection member which is provided in the both ends or one end part of a connection rod, is fitted to the shaft member 6, and connects members.
In the above-described embodiment, the coil spring 23 is provided in the holding groove 21 as an elastic body that biases the lock member 18 so as to protrude to the retaining position A. However, the lock member 18 is retained in place of the coil spring 23. A plate spring or other spring may be provided as the elastic body that is biased so as to protrude to the position A, and rubber or the like may be provided as the elastic body.
