TENSION/TOW MATERIAL LENGTH ADJUSTING DEVICE
PROBLEM TO BE SOLVED: To provide a tension/tow material length adjusting device which has excellent workability and durability and has safety which matches with an international safety reference.SOLUTION: An adjusting device includes a long bolt 11 having a bolt shaft 11b which extends by a specified length from a bolt head part 11a and is threaded with a male screw 11c, a holder 12 consisting of a cover case provided with a gap groove 12, and a fixing and moving hooks 13A, 13B attached to the long bolt and the holder. Relating to the holder 12, a cylindrical hook part of the fixing hook protrudes from one end of a hollow hole through the gap groove 12for insertion, to be bonded to an end part. The cylindrical hook part of the movable hook protrudes from the other end of the hollow hole through the gap groove 12, for insertion for free movement. The long bolt 11 is inserted in the fixing hook 13A where the bolt shaft 11b is bonded to the holder 12, to be screwed in a threaded hole of the movable hook 13B that is attached to the holder 12 for free movement.SELECTED DRAWING: Figure 1
【課題】優れた作業性及び耐久性を有すると共に国際的安全基準に合致した安全性を備えた張架・牽引材長さ調節装置。【解決手段】ボルト頭部１１ａから所定長さ延び雄ネジ１１ｃが刻設されたボルト軸１１ｂを有する長尺ボルト１１と，隙間溝１２１を設けたカバーケースからなるホルダー１２と，長尺ボルト及びホルダーに装着される固定及び移動フック１３Ａ，１３Ｂを備え,ホルダー１２は，中空孔の一端から，固定フックの円筒体のフック部を隙間溝１２１から突出させて挿入して端部に固着し，中空孔の他端から可動フックの円筒体のフック部を隙間溝１２１から突出させて移動自在に挿入し，長尺ボルト１１は，ボルト軸１１ｂがホルダー１２に固着した固定フック１３Ａに挿通され，ホルダー１２に移動自在に装着された可動フック１３Ｂのネジ孔に螺合されている。【選択図】図１
