この考案は背当て体の補強作用並びに背負い帯
の連結板の裏当て作用を兼ねた補強板を有するラ
ンドセルに関する。[Detailed Description of the Invention] This invention relates to a school bag that has a reinforcing plate that serves both to reinforce the back support and to back the connecting plate of the backpack belt.
近年、多見するランドセルは背当て体の内側に

がであつた。このことはランドセルを外観不体裁
にしたり、又、背負い帯の安定性がなくなつて背
負い心地を悪くするといつた欠点があつた。 In recent years, many school bags have been equipped with a single reinforcing plate on the inside of the back support and above the back support. This reinforcing plate maintains the upper part of the backrest in a flat shape, and in addition to the reinforcing function, it also acts as a seat plate for the connecting plate of the backpack belt. Since the tensile force of the shoulder strap applies a concentrated load, the center of the reinforcing plate may become curved or crack. Therefore, the reinforcing plate may no longer be able to maintain the shape of the upper part of the backrest, or may no longer be able to reinforce the upper part. This had disadvantages such as making the school bag look unsightly, and also making the backpack uncomfortable to carry due to the lack of stability of the strap.
この考案は、前記背当て体の補強板の欠点を解

passes through the back support body 1 and connects and fixes both ends of the reinforcing plate 6, which forms a fitted portion 5 below to fit with the fitting portion of the back support plate 3. This relates to a school bag that is connected and fixed to a school bag.

被嵌合部５は嵌合部４の上方からあるいは裏面側
から嵌合でき得るものであり、嵌合部４の裏面と
の接触面を有しているものである。 The backing plate 3 and reinforcing plate 6 are made of synthetic resin. The lower part of the backing plate 3 is a connecting fixing part 3' with the engagement seat plate 2, and the upper part is a fitting part 4 with the reinforcing plate 6. The fitting part 4 is stepped so as to protrude from the surface of the connecting fixing part 3'. The fitting portion 4 has an upper curved portion 11 and a lower curved portion 12 formed by concentric circles on the upper side of the stepped portion and the lower side on the same back surface side. On the other hand, the reinforcing plate 6 forms a fitted part 5 below the center thereof, which fits into the fitting part 4 .
The fitted part 5 can be fitted to the fitting part 4 from above or from the back side, and has a contact surface with the back side of the fitting part 4.
前記裏当て板３と補強板６の背当て体１への取
付作業としては、例えば先づ背当て体１の裏面中
央に裏当て板３を設けるが、表面側に設ける係合

１にビス８で止着する。このように裏当て板３と
補強板６は別体ではあるが、両者は嵌合すること
によつて一体化になつている。従つて背当て体に
対する両者の取付作業は別体であることによる繁
雑性は特になく簡単容易である。 As for the work of attaching the backing plate 3 and the reinforcing plate 6 to the back support body 1, for example, first the backing plate 3 is provided at the center of the back surface of the back support body 1, but the engaging seat plate 2 and the reinforcing plate 6 are installed on the front side. The two are fastened with screws 8 through the backing body, and then the fitted portion 5 of the reinforcing plate 6 is attached to the backing plate 3.
The reinforcing plate (6) is fitted into the fitting part 4 and both ends of the reinforcing plate (6) are fixed to the back support body 1 with screws 8. In this way, although the backing plate 3 and the reinforcing plate 6 are separate bodies, they are integrated by fitting together. Therefore, the work of attaching the two to the backrest is simple and not particularly complicated due to the fact that they are separate bodies.

許容できる嵌合形態になつている。 Next, the effects of the present invention in use will be described. The backing plate 3 and the reinforcing plate 6 are integrated so that the reinforcing plate 6 has a two-layer overlapped part in the center, so the center of the reinforcing plate 6 is extremely strong and will not be damaged by external pressure.
Prevent it from bending. Also, backing plate 3
Since the fitting part 4 can be removed from the fitted part 5 in the pulling direction of the backpack strap 7, the reinforcing plate 6 is concentrated near the center in the longitudinal direction by the tensile force of the backpack strap 7. Since no load is applied, there is no deformation, and even at this time, the upper part of the back support can be maintained flat and reinforced. Even if the fitting part 4 of the backing plate is twisted and comes off from the fitting part 5 as shown in FIG. If the arc surfaces are in contact with a part of the contact area, it is possible for the arc surfaces to slip and return to their original states, so the backing plate 3 can easily control the magnitude and direction of the tensile force on the backpack belt 7.
Provides an acceptable fit.

強板６の変形防止になつている。 In addition, even if bending pressure is simultaneously applied to the left and right sides of the back support body 1, that is, the left and right sides of the reinforcing plate 6 in the same direction, forward or backward, the fitted portion 5 of the reinforcing plate 6 is a backing that is not affected by the bending pressure. Fitting part 4 of plate 3
Since the reinforcing plate 6 is fitted in the reinforcing plate 6 and the bending pressure is controlled, deformation of the reinforcing plate 6 is prevented.
以上の通り、この考案は、補強板と裏当て板の

ている。 As described above, this invention integrates the reinforcing plate and the backing plate in such a way that the reinforcing plate has two overlapping plates at the center where the reinforcing plate is likely to receive a concentrated load. However, this prevents damage to each part due to external pressure. The upper part of the backrest retains its shape and is reinforced even after many years of use, making the schoolbag of this design both attractive in appearance and comfortable to carry.
