By attaching and detaching it, the length of the belt was changed by making the folded ring larger (the function as a string becomes shorter) or smaller (the function as a string becomes longer), but it was bulky And the operation was not smooth, and it couldn't be easily attached to any type of backpack.

[0003]

This has the following disadvantages. (A) Since one string is folded into three layers, it is bulky and heavy. (B) The structure is complicated and cannot be easily attached to any type of backpack.

[0004]

The fastener (1) is used as a string. Strings (3), (6) for connecting to the split parts (2), (5) of the fasteners (7) and string connecting fasteners (7),
Add (8). The tip of (7) is connected to the upper part (9) of the backpack of the backpack, and the tip of (8) is connected to the lower part (10) of the backpack of the backpack. If you open the zipper,
(3), (2), (1), (5) and (6) become one long string. The present invention is a tool for converting the length of a backpack of a backpack having the above configuration.

[0005]

Embodiments of the present invention will be described below. (A) A string (3) is attached to the tip of the cleavage part (2) of the fastener. A string (6) is also attached to the side end (5) of the cleavage part (4) of the fastener. (Tighten (5) and (6).) (B) Attach the string connecting fastener (7) to the tip of the string (3). Similarly, a string connection fastener (8) is attached to the tip of the string (6). (C) Connect the string connecting fastener (7) to the upper part (9) of the backpack belt of the backpack. Similarly, the strap connection fastener (8) is connected to the lower part (10) of the backpack belt of the backpack. The present invention has the above configuration.
