Claims

[Claims for Utility Model Registration] 1. On the inside of the base of the hook body ₁ , which has a rope portion ₁₂ at the base 11 and a hook portion ₁₃ at the tip, there is provided a base for opening and closing the openings ₁₄ of the hook portions _13. 1 ₁ and hook part 1 ₃ hook tip 1
₅ and the base 2 ₁ is the base 1 of the hook body 1 ₁ is the shaft 3
A closing body ₂ is provided which is pivoted and whose tip abutting portion ₂₂ contacts the inside of the hook tip 15 of the hook portion ₁₃ , and a spring 4 is provided between the closing body 2 and the hook body 1 and the spring The elastic force of 4 urges the closing body 2 to connect the abutment to the hook tip ₁₅ of the hook body 1, and the base 2 of the closing body 2
₁ is provided with a stop part 5 that overlaps the base part ₁₁ of the hook body 1 and has a regulating part ₅₁ at the tip facing outside of the base part ₁₁ ,
Moreover, the stop part receiver 6 is positioned outside the base 11 of the hook body ₁ so that its tip overlaps the stop part 5, and the base of the stop part receiver 6 is placed on the side of the hook part ₁₃ of the hook body 1. is fixed by a shaft 7, and a protrusion 8 is provided at a portion that abuts the tip regulating portion ₅₁ of the stop portion 5 on the tip side of the stop portion receiver 6 and restricts rotation of the closing body 2, A spring 9 is provided between the stop part receiver 6 and the hook body 1, and the elastic force of the spring 9 causes the protrusion 8 to constantly come into contact with the regulating part ₅₁ at the tip of the stop part 5, thereby regulating the rotation of the closing part 2. In addition, a protrusion 10 is provided on the base ₁₁ of the hook body 1 in line with the stop part 5, and a protrusion engaging part 52 is provided on the part of the stop part 5 facing the protrusion 10 so that the closing body ₂ can be hooked. A lifeline hook characterized in that it is installed so that there is a small distance A between the openings ₁₄ of the parts 13 and the protrusion 10 when the openings 14 of the parts ₁₃ are closed. 2 The contact portion 2 2 that comes into contact with the hook tip 1 ₅ of the hook portion 1 ₃ of the closing body ₂ has a first contact portion 2 ₂₁ and a first contact portion 2 ₂ . _2. The lifeline hook according to claim 1, further comprising a second contact portion ₂₂₂ for backing up the lifeline hook.
