[Embodiment of the invention]

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a side view for explaining a backrest according to the present embodiment, and FIG. 2 is a diagram for explaining a detachment means.

In FIG. 1, reference numeral 2 denotes a back plate of the school bag 1. Each of the hooks 4 of the attaching / detaching means 3 is hung on the left-right end 2a of the back plate 2 and the back plate 2 is sandwiched. Is done.

The backrest body 5 is a member having a rectangular plate shape, and is composed of a flat plate 6 and a large number of elastic bodies 7, and is covered with the bag body 8 by being accommodated in the bag body 8. . The flat plate 6 is a thin plate made of plastic, can be bent in the thickness direction, and is made lightweight by being made of plastic. The flat plate 6 does not have to be flexible.

A large number of columnar elastic members 7 protrude from one surface of the flat plate 6. By arranging the plurality of elastic bodies 7 vertically and horizontally at predetermined intervals, a large number of irregularities are formed on one surface of the backrest body 5. Then, at least on the one surface side, air can flow between the elastic members 7 to ensure air permeability. The shape of the elastic body 7 is not limited to a cylindrical shape.

The backrest body 5 composed of the elastic body 7 and the flat plate 6 is housed in a mesh-shaped bag body 8 to be protected from the outside, and the front end of the elastic body 7 is connected to the schoolchild via the bag body 8. Touch back 9. By forming the bag 8 into a mesh shape, the air can easily flow between the back 9 and the backrest body 5 and the outside air can flow through the gap between the elastic members 7 in the bag 8.

A zipper (not shown) is provided on the upper portion of the bag 8, and the backrest body 5 can be taken out of the bag 8 by opening the zipper. Two sets of attachment / detachment means 3 are attached to a portion of the bag 8 that contacts the other surface of the flat plate 6 (a portion on the side of the back plate 2) with a predetermined interval vertically.

Each hook 4 of each attaching / detaching means 3 is attached to the bag 8 with a magic tape (trade name), and the attaching / detaching means 3 can be detached from the bag 8. The above-mentioned magic tape (trade name) constitutes a mounting portion.

The attachment / detachment means 3 includes a pair of hooks 4 hooked to the end face on the back plate 2 side, and a regulating portion 10 connecting the pair of hooks 4 to each other. Each of the pair of hooks 4 has a recess 4 a that is hooked to the back plate 2 by inserting the side end 2 a of the back plate 2 of the school bag 1. By inserting the recesses 4a of the hooks 4 into the side end surfaces of the back plate 2, a pair of hooks 4 whose spacing is regulated by the regulating portions 10 described later sandwich the back plate 2 from the left and right. Thus, the attaching / detaching means 3, that is, the backrest body 5 is supported by the backboard 2 (the school bag 1).

The restricting portion 10 includes a pair of band members 10 a extending from each of the hook portions 4 to the other hook portions 4, and a fastener 10 b for connecting the tip portions 2 a of the band members 10 a to each other. Consists of By adjusting the fastening position between the band members 10a by the fasteners 10b, the interval between the pair of hooks 4 can be adjusted, and the interval is regulated to a constant value.

Next, the use of the backrest having the above-described structure, functions and effects, and the like will be described. First, the interval between the pair of hooks 4 is adjusted by the fastener 10b in accordance with the width of the back plate 2 of the school bag 1 to be mounted. At this time, if the interval between the pair of hooks 4 is changed, the bag body 8 becomes wrinkled. Therefore, the attaching / detaching means 3 may be removed from the bag body 8 and may be reattached.

Although the width of the back plate 2 varies by about 3 cm depending on the type of the school bag 1, when the school bag 1 to be used is specified and used, the restricting portion 10 is formed by a single band. It is not necessary that the interval can be adjusted, for example, by constructing from.

Further, the structure of the restricting portion 10 is not limited to the above-described structure. If the pair of engaging portions 4 can be connected to each other in a state where the distance can be adjusted, other well-known configurations may be adopted. Good.

Next, the side ends 2 a of the back plate 2 are inserted into the recesses 4 a of the respective hooks 4, and the hooks 4 are hooked on the side ends 2 a of the respective back plates 2. As a result, the attaching / detaching means 3 sandwiches the back plate 2 from the left and right, and the back support body 5 is attached to the school bag 1.

When the backpack is attached as described above and the school bag 1 is carried on the back, only the distal end portion 2 a of the elastic body 7 abuts on the back 9 of the school child via the mesh bag 8. Air permeability is ensured on the back 9 of the schoolchild carrying the school bag 1. As a result, the back 9 is less likely to become stuffy even in summer.

Further, in cool seasons other than summertime, the backpack can be removed and the school bag 1 can be used as it is, and the backrest can be removed, so that the backrest can be easily washed. In addition, since the backrest body 5 is covered with the mesh-shaped bag body 8, the backrest body 5 is less likely to be soiled, and the ventilation with the outside air is secured. The bag body 8 can be easily washed with a washing machine or the like by removing the backrest body 5, and the backrest body 5 removed from the bag body 8 can also be washed. At this time, since the attaching / detaching means 3 is detachable from the bag body 8, it does not hinder the washing.

Here, in this embodiment, the case where the backrest body 5 is covered with the bag body 8 has been described, but even if the bag body 8 is not provided, the back 9 can be prevented from getting stuffy. Further, the backrest body 5 is not limited to the above configuration. In short, at least one side of the school child's back 9 that is in contact with the back 9 has elasticity at least in the thickness direction and plays a role of a pad. It would be nice. For example, the backrest body may be formed from a plate-shaped elastic member having a predetermined thickness, and a plurality of irregularities having a predetermined depth may be formed on one surface thereof. The above-mentioned predetermined depth refers to a depth at which the entire surface of the elastic member does not contact the back when pressed against the back in consideration of the rigidity of the elastic member.

Further, the attaching / detaching means 3 is not limited to the above configuration. The backrest does not need to transmit the load from the school bag 1 and only needs to be attached to the school bag 1 with a supporting force that does not drop from the school bag 1. It may be configured to have a force for clamping the side end 2a of the back plate 2 with a ring or the like. In this case, the regulation unit 10 is not necessarily required. Further, the position of attachment to the school bag 1 is not limited to the one using the side end 2a of the back plate 2; for example, the school bag can be hooked on a metal fitting (not shown) for attaching a shoulder strap (not shown). 1 may be supported, or may be supported by hanging from the lid piece 1a. In short, the backrest body 5 only needs to be supported by the school bag 1 in a state of being located between the backboard 2 and the back 9 of the schoolchild.

However, the supporting structure is simplified when the back plate 2 is supported on the school bag 1 using the side end 2a of the back plate 2 having a predetermined rigidity.

[Effect of the invention]

 As described above, adopting the present invention has an effect that the backpack of a schoolchild carrying a schoolbag can be prevented from being stuffy only when it is attached to the schoolbag only when it is desired to be used, for example, in a hot summer season.

Further, even if the back side has an uneven shape to ensure air permeability, the back of a schoolchild does not hurt because of its elasticity. At this time, by adopting the invention of claim 2, it is possible to reliably support the backrest to the backpack by using the side end portion of the strong backboard regardless of the type (size) of the backpack. .

In addition, by adopting the invention of claim 3, air permeability on the back side of the backrest is reliably ensured. In addition, by adopting the invention of claim 4, the backrest body is covered and the backrest body is protected in a state where air permeability is ensured, and the bag for protecting the backrest body is easily washed.
