この考案は、ランドセルの背当て部の改良に関
するものである。従来のランドセルにおいては、
背当て部の芯材にベニヤ板を用いていたため、何
かに当つて割れたりして強度に問題があり、更
に、ベニヤ板の重量によりランドセルを重くする

ことを目的とするものである。[Detailed Description of the Invention] This invention relates to an improvement of the back rest of a school bag. In conventional school bags,
Since plywood was used as the core material for the backrest, there was a problem with its strength as it could break if it hit something, and the weight of the plywood made the school bag heavier. Therefore, the object of this invention is to provide a back rest for a school bag that is lightweight and strong.
以下、実施例として示した図面に従つて、この
考案の構成を説明する。 The configuration of this invention will be explained below with reference to the drawings shown as examples.
先ず、第１図に見る様に、ランドセル１は、背
当て部２、マチ部３、底部４及び前面部５により
本体部を構成し、蓋６の一端縁を背当て部２の上
端縁に接続している。 First, as shown in FIG. 1, the school bag 1 has a main body composed of a back part 2, a gusset part 3, a bottom part 4, and a front part 5, and one edge of the lid 6 is attached to the upper edge of the back part 2. Connected.
そして、前記背当て部２は、第２図に見る様
に、板状の芯材７を合成皮革等の生地８でカバー
して構成しているが、前記芯材７は、スポンジの
様に弾力性のある発泡合成樹脂により構成してい
る。この材料は、従来芯材として用いられてきた
ベニヤ板に比較して極めて軽量であり、また弾性
があるために衝撃に対しても十分な強度を有する
ものである。 As shown in FIG. 2, the backrest 2 is constructed by covering a plate-shaped core material 7 with a fabric 8 such as synthetic leather. Constructed from elastic synthetic resin foam. This material is extremely lightweight compared to plywood, which has been conventionally used as a core material, and has sufficient strength against impact due to its elasticity.
板状の発泡合成樹脂を芯材７に用いた背当て部
２は、その両側辺を両マチ部３，３の縁に、下辺
を底部４の縁にそれぞれ縫着・接続している。こ
うして、背当て部２、両マチ部３，３、底部４及
び前面部５により箱状の本体部を形成しているの
である。マチ部３，３、底部４及び前面部５は、
公知の方法によりある程度の剛性をもつて略Ｕ字
状に一体的に形成してあるので、背当て部２の両
側辺及び下辺はしつかりと保持されることができ
る。なお、背当て部２の上辺は縫着されていな
い。 The back support part 2, which uses a plate-shaped foamed synthetic resin as the core material 7, has its both sides sewn and connected to the edges of both gusset parts 3, 3, and its lower side to the edge of the bottom part 4, respectively. In this way, the backrest part 2, both gusset parts 3, 3, the bottom part 4, and the front part 5 form a box-shaped main body part. The gusset parts 3, 3, the bottom part 4 and the front part 5 are
Since it is integrally formed into a substantially U-shape with a certain degree of rigidity by a known method, both sides and the lower side of the back support part 2 can be firmly held. Note that the upper side of the backrest part 2 is not sewn.
そこで、背当て部２の上辺付近には、第２図に
見るように、生地８と蓋６の端縁間に細長い棒状
の補強用芯材９を配置・固定している。この補強
用芯材９により、背当て部２の上辺を補強して変
形等を回避しているのである。 Therefore, near the upper side of the backrest part 2, as shown in FIG. 2, an elongated rod-shaped reinforcing core material 9 is arranged and fixed between the edges of the fabric 8 and the lid 6. This reinforcing core material 9 reinforces the upper side of the back rest 2 to avoid deformation or the like.
すなわち、背当て部２の上端近くの左右に形成
したボルト穴１０間にピアノ線やはがね等の金属
より成る棒状の芯材９を配し、この芯材９を蓋６
の端縁で被つて固定し、芯材９の上下において、
背当て部２と蓋６とを２本のミシン糸１１，１１
で縫着している。更に、背当て部２の上端左右の
角部にＵ字状に折曲げる補強材１２を嵌め込み、
ボルト１３で固定し、蓋６と背当て部２とを締め
付けている。 That is, a rod-shaped core material 9 made of metal such as piano wire or steel is arranged between the bolt holes 10 formed on the left and right sides near the upper end of the backrest part 2, and this core material 9 is inserted into the lid 6.
Cover and fix with the edge of the core material 9, at the top and bottom of the core material 9,
The backrest part 2 and the lid 6 are connected with two sewing threads 11, 11.
It is sewn with. Furthermore, reinforcing members 12 bent into a U-shape are fitted into the left and right corners of the upper end of the backrest part 2,
They are fixed with bolts 13, and the lid 6 and the backrest 2 are tightened.
この場合、補強材１２とボルト１３の鍔部が芯
材９の左右両端部を押圧するため、芯材９の端部
がランドセルの外部に突き出るのを阻止してい
る。 In this case, the reinforcing material 12 and the flanges of the bolts 13 press both left and right ends of the core material 9, thereby preventing the ends of the core material 9 from protruding to the outside of the school bag.
尚、芯材９は、丸線又は半丸線（断面が半円形
の棒状のもの）のいずれも実施可能である。 Note that the core material 9 can be either a round wire or a semi-round wire (a bar-shaped wire with a semicircular cross section).
この考案は、上述の構成を有するものであり、
従つて以下のような優れた効果を有する。 This invention has the above-mentioned configuration,
Therefore, it has the following excellent effects.
芯材７に発泡合成樹脂板を用いたため、ベニ
ヤ板に比べて非常に軽量であり、しかも弾性が
あつて衝撃に強いため、何らかの原因で衝撃が
加わつてもベニヤ板のように破損する恐れが少
ない。 Since a foamed synthetic resin board is used for the core material 7, it is much lighter than a plywood board, and is more elastic and resistant to impact, so there is less risk of damage like a plywood board even if an impact is applied for some reason.
補強用芯材９を背当て部２の上辺付近に設け
て、マチ部３や底部４に接続されない背当て部
２の上辺を補強したため、背当て部２の周囲全
体がしつかりと支持され、従つて軽量であるに
かかわらず強度が大である。 Since the reinforcing core material 9 is provided near the upper side of the back rest part 2 to reinforce the upper side of the back rest part 2 that is not connected to the gusset part 3 or the bottom part 4, the entire periphery of the back rest part 2 is firmly supported. Therefore, although it is lightweight, it is strong.
従来の背当て部では、肩掛けバンドの一端を
係合するために上辺に金属製棒材が露出して取
り付けてあつたのに対し、補強用芯材９を蓋６
の端縁で被つて固定しているので、当該芯材９
が外部からまつたく見えず、体裁が良い。 In the conventional backrest part, a metal rod was exposed and attached to the upper side in order to engage one end of the shoulder strap, whereas the reinforcing core material 9 was attached to the lid 6.
Since it is covered and fixed by the edge of the core material 9,
It is not visible from the outside and has a good appearance.
