Description

[Detailed explanation of the invention] This invention has one end edge 1′ in the center of one end of the synthetic resin porous unevenness 1.
A horizontally long hole 2 is drilled along the other edge 1'', and a pair of hanging rings 3,
The present invention relates to a back support for a school bag provided with the following.

The porous uneven board 1 has a surface layer and a back layer, and the surface layer is a reticulated hardened molded board 4, and the back layer is a cushioning porous network made by meandering stretched strips 5 made of synthetic resin and knitted with binding threads 6, and the surrounding The front and back layers are sewn together or the front and back layers are combined with a border material 7 to form an integrated back support.

In the figure, 8 indicates the edge material of the horizontally elongated hole 2, 9 indicates the insertion hole for the removable hanging ring 3, 10 indicates the sewn part of the elastic hanging ring 3, and 1

Shoulder belt upper end mounting bracket 1.14° 14 is a lower end mounting bracket, 15 is a school bag hanging bracket that can be raised and lowered freely, 16 is a rotatable support protrusion of the lower end attachment bracket 14, 17 is a belt buckle, and 18 is a porous unevenness. The convex portion 19 of the plate 1 is a concave portion.

Therefore, the shoulder bell (20.20) provided on the upper part of the back plate 11 of the school bag 12, its upper end fitting 13.13, and the school bag hanging fitting 15 are inserted into the horizontally elongated hole 2, and the third

0' lower end mounting bracket 14.14, above bell) -
20 and 20' are connected with buckles 17, and the school bag 12 is carried on the back as shown in FIG. 6, and the porous uneven plate 1 is interposed between the back plate 11 and the back, and the same uneven plate as the back Ventilation holes are formed between the porous and uneven plates 1 to allow sweat from the back to evaporate from the porous uneven plates 1 in the summer.

The unevenness on the front and back sides of the porous uneven board 1 comes into contact with the clothes on the back and the back plate 11, so that the school bag 12 is in close contact with the child's back with little risk of it slipping off the child's back.

Conventionally, the school bag 12 is made of leather, synthetic leather, leather, etc. that does not have water absorbency or breathability, and since the back of the school bag is in close contact with the back of the elementary school child, it inhibits the evaporation of sweat on the back in the summer and causes the school bag to evaporate along with clothes. The child's back easily gets wet and is extremely uncomfortable, and there is a defect in which heat rash and heat rashes occur easily.In winter, the cold of the school bag 12 can be felt on the back through clothing, and there is a risk that children may dislike using the school bag. .

Since the present invention is constructed as described above, it can be attached to and removed from the back plate 11 of the school bag 12 very easily.
A large number of ventilation holes communicating with the outside air can be formed between the body and the back, and in the summer, sweat at the contact area between the back and the porous uneven board 1 is well evaporated, preventing the shirt from getting wet due to sweat. It is extremely comfortable and hygienic to use, and in winter, the porous uneven board 1 prevents the cold of the school bag 12 from being transmitted to the back, and the cushioning porous mesh forming the back layer of the uneven board 1 prevents the inside of the ventilation hole from being transferred. It is possible to prevent cold air from entering the school bag from the outside, thereby preventing the back from getting cold, allowing the child to use the school bag 12 smoothly in the winter, and providing a back support for the school bag 12 that can be used in both summer and winter. Instead, the unevenness on the front and back sides of the uneven board 1 comes into contact with the clothing on the back and the back plate 11, preventing the school bag 12 from slipping down from the back, making it possible to use it reliably and safely. The back support has the feature that it can be easily removed and washed, allowing the back support to be used extremely cleanly.
