Claims

[Scope of utility model registration request]

In the mounting bracket for attaching a band for fixing the legs by hanging between one side and the other side of the underwater fin foot passage, each of the above-mentioned mounting brackets 1 is attached to the side parts 4 and 5. Main body frames 9 and 2 attached to each
The band lock part 7 is formed on one side of the body frame 23, and the band hook part 8 is formed on the other side of the body frame 23. Attached axis pin 24
The end portion 6a of the band 6, which is formed by a band 6 and has lock step portions 25 formed at predetermined intervals along the width direction on the back surface 6b, is wound from the inside to the outside of the shaft pin 24. On the other hand, the band lock part 7 has a support shaft 10 attached to the body frame 9 so as to be parallel to the shaft pin 24, and this support shaft 10 has a lock end at the tip. A lock pawl 11 having a portion 12 formed thereon is rotatably supported, and this lock pawl 11 is always urged by a spring 14 so that its lock end 12 comes into contact with the back surface 6b of the band 6. Raise the lock pawl 11 against the spring, and insert the lock end 12 formed at the tip onto the back surface 6b of the band.
When the band 6 is moved toward and away from the lock, the band 6 can be moved both in the tightening direction and in the loosening direction, and the locking end 12 of the locking pawl 11 and the back surface 6b of the band
is configured as a one-way locking mechanism R that engages only when the band 6 is pulled in the tightening direction in the normal state where the band 6 is in contact with the pressing force of the spring 14. Band mounting bracket for underwater fins.
