The shoulder belt mounting device for a school bag according to the present invention is provided above the backrest Rp of the school bag R. The mounting body 1 has a plate-like body provided with an insertion space 1a having a vertically long cross-sectional shape. A connection ring 2 having a flat side and a mounting portion 2a having a pair of bent portions C1, a lower side portion having a flat insertion portion 2b having a pair of bent portions C2, and a mounting portion 2a of the connection ring 2; And an elastic body 3 provided with a fitting part 3a. The insertion part 2b of the connection ring 2 is inserted into the insertion space 1a of the attachment body 1, and the elastic body 3 is inserted into the attachment part 2a of the connection ring 2. 3 is fitted, and the upper end of the shoulder belt 4 is fixed to the elastic body 3.
[0009]
Further, the shoulder belt mounting device for a school bag according to the present invention is provided with an opening 1b communicating with the insertion space 1a substantially at the upper center of the mounting body 1, and a substantially Ω-shaped suspension ring 5 is inserted from the opening 1b into the insertion space 1a. And the suspension ring 5 is attached.
[0010]
Further, in the shoulder belt mounting device for a school bag of the present invention, the bent portion C1 of the mounting portion 2a of the connection ring 2 can be formed upward or downward, and the bent portion Cb of the insertion portion 2b of the connection ring 2 can be bent. The part C2 may be formed below.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of a shoulder belt attachment for a school bag according to the present invention will be described below in detail with reference to the drawings.
[0012]
FIGS. 1 to 4 show an embodiment of the shoulder strap mounting device of the school bag of the present invention, and FIGS. 5 to 8 show other embodiments of the shoulder belt mounting device of the school bag of the present invention. In any of the embodiments, the shoulder belt mounting device for the school bag of the present invention is to be mounted on the upper part of the backrest Rp of the school bag R, and the plate-shaped body is provided with the insertion space 1a having a vertically long cross-sectional shape. A connection ring 2 having an attachment body 1 and an attachment portion 2a having a pair of bent portions C1 by flattening both sides of an upper side, and an insertion portion 2b having a pair of bent portions C2 by flattening a lower side portion; The elastic member 3 is provided with a fitting portion 3a for fitting the connection ring 2 into the mounting portion 2a.
[0013]
The shoulder belt mounting device for a school bag of the present invention inserts the insertion portion 2b of the connection ring 2 into the insertion space 1a of the attachment body 1 and further fits the elastic body 3 into the attachment portion 2a of the connection ring 2. The upper end of the shoulder belt 4 is fixed to the elastic member 3 by fitting the insertion portion 3a. The lower end of the shoulder belt 4 is attached to a fixture (not shown) provided at the bottom of the school bag R. The upper portion of the backrest Rp refers to the uppermost end of the backrest Rp or a position slightly lowered from the uppermost end.
[0014]
With this configuration, the shoulder belt mounting device of the school bag of the present invention prevents the connecting ring 2 from rotating in the insertion space 1a of the mounting body 1 and the upper end of the shoulder belt 4 The upper side does not rotate.
[0015]
The mounting body 1 is made of a metal plate, a synthetic resin plate, or the like, and the insertion space 1a of the mounting body 1 is a bent space of a two-folded plate-like body or a two-layered plate-like body. It may be a through-hole provided between them. Further, an opening 1b communicating with the insertion space 1a is provided substantially at the upper center of the mounting body 1, and the leg 5a of the substantially Ω-shaped suspension ring 5 is inserted from the opening 1b into the insertion space 1a.
