Abstract:
PROBLEM TO BE SOLVED: To protect a user from an unexpected and sudden external force.
SOLUTION: A thin strap body 20 for attaching an article to be carried is passed from the inside to an attach hole 34 of a link 30, and a knot 21 is supported at the peripheral edge part of the attach hole 34. Concerning a main body 10 of strap to be hung on the body of the user, link holes 11 at both terminal parts are fitted with supporting shafts formed on the inner bases of first and second link pieces 31 and 32. Slopes 39a and 39b are formed on the partial peripheral surfaces of the supporting shafts 37a and 37b. The peripheral edge parts of first and second link elements 31 and 32 are overlapped and a recessed part 35 and a projecting part 36 are engaged. Then, when tensile load more than a fixed value is operated upon the article to be carried, stress from the main body 10 of strap is operated upon the slopes 39a and 39b, the recessed part 35 and projecting part 36 are disengaged by the component of force, the first and second link elements 31 and 32 are expanded and the main body 10 of strap is separated.
