Description

[Detailed explanation of the invention] This invention relates to improving the shoulder strap that is attached to school bags, and its purpose is to provide a flexible feeling when worn over the eyebrows so that it does not put any strain on the eyebrows. In addition, there is no risk of damage to the connecting parts, and the retention holes will not deform or the internal constituent materials of the belt will be exposed even after long-term use. This is what we are trying to provide.

In this type of shoulder strap, the upper part of the belt is placed on the shoulder, and the lower part is detachably connected to the connecting band, but if the belt is made to have a flexible structure so as not to put a burden on the shoulders, the belt can be attached to the connecting band. The attachment/detachment part is easily damaged, and if the entire attachment/detachment part is covered with a hard material to prevent damage, it would place a heavy burden on the eyebrows of the child using it.

This invention solves the drawbacks of the above-mentioned conventional example, and its configuration will be explained below with reference to the drawings showing one embodiment.

Reference numeral 1 is a school bag, and two shoulder straps rotatably connect a bell l-3 to a fixture 2 fixed to the upper part of the back.
A connecting band 5 is rotatably connected to a connecting fitting 4 fixed to the lower part.

Furthermore, the shoulder strap has a plurality of holes 6 arranged in series at appropriate intervals in the lower attachment/detachment portion 3a of the belt 3, and the shoulder strap is secured to the shoulder strap by means of an engaging fitting 8 with a claw 7 attached to the end of the connecting band 5. The dimensions of the belt 3 are adjusted so that it is connected as shown in Figure 1.

In this shoulder strap, the belt 3 has a core 9 made of an elastic material such as sponge, the outside of which is covered with a cover 10 made of soft fabric, and an outer surface 11 made of hard fabric.
At the same time, a lining material 12 made of hard fabric is provided in the detachable part 3a on the lower side of the back surface, and the outer peripheral edge is sewn with sewing thread 13, and a plurality of holes 6 are connected at appropriate intervals in the detachable part 3a. It has a built-in structure.

In addition, in FIG. 2, the fixing hole 14 formed at the upper end of the belt 3 of the shoulder strap is used to fix it to the fixture 2, and the hole 15 fixes the end of the lining 12. This is a rivet.

This invention has the above-mentioned structure, and since the shoulder part is separated only by the cover 10 made of soft fabric and the core 9 made of elastic material, it gives an extremely soft feeling when worn on the shoulder. There is no burden on the shoulders, and since the attachment/detachment part 3a is provided with a hard fabric lining 12, the claw 7 is inserted into the hole 6, the engagement fitting 8 is repeatedly attached and detached, and then The shoulder strap of the school bag according to this invention has excellent practical effects, such as there is no risk of damage to the attachment/detachment part 3a even when used for a long period of time.
