Title:
SHOULDER BELT UPPER END FASTENER FOR KNAPSACK
Document Type and Number:
Japanese Patent JP3909448
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To make an attached shoulder belt fit to the surrounding area of a user's shoulders by forming the approximately W-shaped part of a connecting ring in such a state as a rising gradient from the inner bent end of the ring.
SOLUTION: One row of an insertion part 2 is formed on the bent part formed out of a twofold metallic plate. Also, a connecting ring 5 has internally bent ends 5b and 5b at both ends of an approximately W-shaped part 5a. In addition, the internally bent parts 5b and 5b are formed to be capable of freely turning, and attached to the insertion part 2. The approximately W-shaped part 5a of the connecting ring 5 is inclined so as to have a rising gradient from the internally bent ends 5a and 5b. In this case, right and left shoulder belts, when connected to the connecting ring 5, are kept in such a state as narrowed toward a center as well as in such a state as twisted approixmately like the figure of 8. Also, when a knapsack with the shoulder belts is put on a user's back, the shoulder belts are aligned along a slope from his/her shoulders to the chest, and the shoulder belts are well fit to an area surrounding his/her shoulders.
