<p><P>PROBLEM TO BE SOLVED: To provide a strap (51) that saves the handling time in opening/closing and simplifies looping by coupling, when the strap is equipped with both an opening/closing part operating by user's intention and an emergency detaching part working by excess tension, and that can also reduce cost. <P>SOLUTION: The strap is provided with a strap part (9), a first engaging part (7R) at one end and a second engaging part (7L) at the other end. The first and second engaging parts (7R, 7L) are made connectible through a relay joint (8) that has at one end third engaging parts (8b, 8c) for engaging with the first engaging part (7R) and at the other end a fourth engaging part (8f) for engaging with the second engaging part (7L). The first and the third engaging parts (7R) (8b, 8c) engaged in-between are released from the engagement by a specific or higher tension imparted to the strap part (9). The second and the fourth engaging part (7L) (8f) are engaged with each other by a force in a direction different from the tension, the engagement is released by a force reverse to it. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
