Description

本考案は、学童が使用するランドセルの背負いベルトが、歩行中にランドセルの重さで左右に開くのを防止して背負い易くする補助ベルトの改良に関する。 The present invention relates to an improvement of an auxiliary belt that prevents the backpack belt of a school bag used by school children from opening to the left and right due to the weight of the school bag while walking, making it easier to carry.

従来、小学生が使用するランドセルは、教科書や副教材、さらには体操具などを収容するためかなりの重量となる。特に１年生から３年生までの低学年の学童にとって、重いランドセルを背負っての通学はかなりの負担である。 Traditionally, school bags used by elementary school students are quite heavy because they accommodate textbooks, supplementary teaching materials, and gymnastics equipment. Especially for lower grade school children from the first grade to the third grade, going to school with a heavy school bag on their back is a considerable burden.

一方、ランドセルに取付けてある背負いベルトは、学童の身長にあわせてある程度長さを調節することが可能に形成してあるが、身長が低い低学年、特に小柄な学童は背負いベルトを調整しても重いランドセルを背負うとランドセルが後方へずれたり、背負いベルトの肩当て部が学童の肩から外れたりして広がりやすい。また、背負いベルトが広がると低学年の学童にとってランドセルの重心が移動するため、より重くなって背負いにくくなる。さらに、背負いベルトが広がった状態での歩行は、ランドセルが左右に揺れて歩きにくくて疲れやすい。さらには、歩行中にランドセルが安定しないと身体が左右にブレて歩行が危険であるなどの多くの問題点を有している。 On the other hand, the backpack belt attached to the school bag is formed so that the length can be adjusted to some extent according to the height of the school child, but in the lower grades with a short height, especially for small school children, adjust the backpack belt. If you carry a heavy school bag on your back, the school bag will shift backwards, and the shoulder rest of the backpack belt will come off the shoulders of school children, making it easy to spread. In addition, when the backpack belt is widened, the center of gravity of the school bag moves for school children in the lower grades, which makes it heavier and more difficult to carry. Furthermore, when walking with the backpack belt spread out, the school bag swings from side to side, making it difficult to walk and making it easy to get tired. Furthermore, if the school bag is not stable during walking, the body shakes from side to side and walking is dangerous.

そのため、ランドセルの背負いベルトが広がるのを防止するため、互いの背負いベルトの間に広がり防止用の連結ベルトを取付けてランドセルを背負い易くしているものが知られている（例えば、特許文献１、２参照）。 Therefore, in order to prevent the backpack belts of the school bag from spreading, it is known that a connecting belt for preventing the spread is attached between the backpack belts to make it easy to carry the school bag (for example, Patent Document 1, Patent Document 1, 2).

これらの連結ベルトは、ランドセルの背負いベルトに取付ける場合、それぞれベルト部の先端に着脱可能な雌雄一対の連結具を取付け、他端を背負いベルトの任意個所に巻きつける装着部を設けて使用している。 When attaching these connecting belts to the backpack belt of a school bag, a pair of removable male and female connecting tools are attached to the tip of each belt part, and the other end is provided with a mounting part to be wound around any part of the backpack belt. There is.

したがって、連結ベルトを背負いベルトへ取付ける場合、装着部が背負いベルトへの巻きつけが弱いと、使用中に連結ベルトが下がって背負いベルトが広がる恐れがある。また、背負いベルトに連結ベルトを巻きつけてあるだけであるため、使用中に外れたりするおそれがある。さらには、連結ベルトの装着位置が学童のお腹の部分に位置するので、背負いベルトの肩当部分が学童の肩から下がって広がりやすいため、ランドセルが左右に揺れ歩きにくい。特に低学年の学童には負担が大きく疲れやすいなどの問題点を有している。 Therefore, when the connecting belt is attached to the backpack belt, if the mounting portion is weakly wrapped around the backpack belt, the connecting belt may be lowered and the backpack belt may be expanded during use. In addition, since the connecting belt is simply wrapped around the backpack belt, it may come off during use. Furthermore, since the connecting belt is attached to the abdomen of the school child, the shoulder rest of the backpack belt easily spreads down from the shoulder of the school child, making it difficult for the school bag to swing from side to side. In particular, it has problems such as being burdensome and easy to get tired for school children in the lower grades.

そこで、本考案は、背負いベルトに取付ける幅広がり防止用の連結ベルトが使用中にズリ下がったり、外れたりすることなく安全で確実に使用することができるランドセルの背負いベルトに取付ける補助ベルトを提供することを目的とする。 Therefore, the present invention provides an auxiliary belt to be attached to the backpack belt of a school bag that can be safely and surely used without the connecting belt for preventing width spread attached to the backpack belt slipping down or coming off during use. The purpose is.

上記課題を達成するため、本考案は、一側に連結孔１８を設け、中央上下方向にベルト孔１６を設けてなる一対の装着部１３、１３の前記連結孔１８と、一対のベルト部１１ａ、１１ｂの一端をそれぞれ連結し、該ベルト部１１ａ、１１ｂの他端に雌雄一対で互いに着脱可能に連結する接続具２０を取付けてなり、前記装着部１３のベルト孔１６に背負いベルト３のベルト連結部９を挿通して肩当部５方向に装着部１３を移動させ、この装着部１３のベルト孔１６の内壁面全体と前記肩当部５の胸部５ｂの外周面全体を面接触させて狭着支持させてなることを特徴とする。また、前記装着部１３のベルト孔１６は、上方開口部１６ａを背負いベルト３の肩当部５を構成する胸部５ｂの横幅と厚さよりやや狭い横幅と厚さに開口し、下方開口部１６ｂは背負いベルト３のベルト連結部９が挿通可能な横幅と厚さに開口してなり、この装着部１３の上方開口部１６ａからベルト連結部９の下端を挿通して背負いベルト３の肩当部５方向に装着部１３を移動させ、この装着部１３のベルト孔１６の内壁面全体と前記肩当部５の胸部５ｂの外周面全体と面接触させて狭着させることにより装着部１３を肩ベルト５の胸部５ｂに着脱可能に狭着支持させてなることを特徴とする。さらには、装着部１３のベルト孔１７は、内壁面の上下方向全体に凹凸部１９を設けてなることを特徴とする。さらにはまた、前記ベルト部１１ａ、１１ｂにそれぞれ連結した雌雄一対の接続具２０は、一端に装着部１３を連結したベルト部１１ａの他端に該ベルト部の長さを調節する調節部２８を介して雌部片２５を取付け、一方に装着部１３を取付けたベルト部１１ｂの他端に雄部片２１を連結し、前記雄部片２１と雌部片２５を互いに着脱可能に連結してなることを特徴とする。また、前記装着部１３は、表面に光に反射する反射板、または、任意形状のキャラクター図形などを表記する表示部３５を設けてなることを特徴とする。 In order to achieve the above object, in the present invention, the connecting hole 18 of the pair of mounting portions 13 and 13 having the connecting hole 18 provided on one side and the belt hole 16 provided in the central vertical direction and the pair of belt portions 11a. , 11b are connected to each other, and a connector 20 is attached to the other ends of the belt portions 11a and 11b so as to be detachably connected to each other by a pair of males and females. The mounting portion 13 is moved in the direction of the shoulder rest portion 5 through the connecting portion 9, and the entire inner wall surface of the belt hole 16 of the mounting portion 13 and the entire outer peripheral surface of the chest portion 5b of the shoulder rest portion 5 are brought into surface contact with each other for narrowing. It is characterized by being supported. Further, the belt hole 16 of the mounting portion 13 has an upper opening 16a opened to a width and thickness slightly narrower than the width and thickness of the chest 5b constituting the shoulder rest portion 5 of the belt 3, and the lower opening 16b is a backrest. The belt connecting portion 9 of the belt 3 is opened to have a width and thickness that can be inserted, and the lower end of the belt connecting portion 9 is inserted from the upper opening 16a of the mounting portion 13 in the direction of the shoulder rest portion 5 of the backpack belt 3. By moving the mounting portion 13 so that the entire inner wall surface of the belt hole 16 of the mounting portion 13 and the entire outer peripheral surface of the chest portion 5b of the shoulder rest portion 5 are brought into surface contact with each other and narrowly fitted, the mounting portion 13 is brought into close contact with the chest portion of the shoulder belt 5. It is characterized in that it is detachably supported by a narrow attachment to 5b. Further, the belt hole 17 of the mounting portion 13 is characterized in that the uneven portion 19 is provided on the entire inner wall surface in the vertical direction. Furthermore, the pair of male and female connectors 20 connected to the belt portions 11a and 11b each have an adjusting portion 28 for adjusting the length of the belt portion at the other end of the belt portion 11a to which the mounting portion 13 is connected to one end. The female part piece 25 is attached to the other end of the belt portion 11b to which the attachment portion 13 is attached, and the male portion piece 21 is connected to the other end of the belt portion 11b, and the male portion piece 21 and the female portion piece 25 are detachably connected to each other. It is characterized by becoming. Further, the mounting unit 13 is characterized in that a reflecting plate that reflects light or a display unit 35 that displays a character figure of an arbitrary shape is provided on the surface of the mounting unit 13.

したがって、補助ベルト１０は、一対のベルト部１１ａ、１１ｂの一端にそれぞれ取付けた装着部１３のベルト孔１６に背負いベルト３，３のベルト連結部９の先端を挿通して肩当部５の正面胸部５ｂ方向に移動させて狭着固定させることにより、補助ベルト１０を肩当部５の所定位置に簡単に取付けることができる。また、背負いベルト３に狭着固定した補助ベルト１０の装着部１３は、学童の登下校時にランドセルを揺さぶられても肩当部５の外周面とベルト孔１６の内壁面とが全面当接しているため摩擦抵抗によりズレたり脱落するおそれはない。さらに、補助ベルト１０の装着部１３を肩当部５の胸部５ｂ付近に取付けたことにより、登下校中にランドセルを揺さぶっても背負ベルト３の肩当部５が肩からズレたり広がるのを防止することができるので、低学年の学童でも肩に負担がかからずに背負うことができる。さらにはまた、装着部１３の表面に設けた表示部３５に反射板を取付けることにより学童を交通事故から守り安全を図ることができ、また、表示部３５に漫画のキャラクター図形などを張ることにより学童が興味を引きランドセルの購買意欲を増進させることができる。さらには、ベルト部１１、１１に取付けた接続具２０は、ワンタッチで簡単に着脱連結操作をすることができるので、低学年の学童でも容易に取り扱うことができる。 Therefore, in the auxiliary belt 10, the tip of the belt connecting portion 9 of the backpack belts 3 and 3 is inserted into the belt hole 16 of the mounting portion 13 attached to one end of the pair of belt portions 11a and 11b, respectively, and the front chest portion of the shoulder rest portion 5. The auxiliary belt 10 can be easily attached to a predetermined position of the shoulder rest portion 5 by moving it in the 5b direction and fixing it in a narrow position. Further, in the mounting portion 13 of the auxiliary belt 10 narrowly fixed to the backpack belt 3, the outer peripheral surface of the shoulder rest portion 5 and the inner wall surface of the belt hole 16 are in full contact with each other even if the school bag is shaken when the school child goes to and from school. Therefore, there is no risk of slipping or falling off due to frictional resistance. Further, by attaching the mounting portion 13 of the auxiliary belt 10 to the vicinity of the chest 5b of the shoulder rest portion 5, it is possible to prevent the shoulder rest portion 5 of the backpack belt 3 from slipping or spreading from the shoulder even if the school bag is shaken while going to and from school. Therefore, even younger school children can carry it on their shoulders without burdening their shoulders. Furthermore, by attaching a reflector to the display unit 35 provided on the surface of the mounting unit 13, it is possible to protect school children from traffic accidents and ensure safety, and by putting a cartoon character figure or the like on the display unit 35.

この補助ベルト１０は、図１、３に示すごとく、合成繊維材を帯状に形成した一対のベルト部１１ａ、１１ｂと、該ベルト部の一端にランドセル１の背負いベルト３に狭着固定させる硬質合成樹脂材により形成した装着部１３と、前記ベルト部の他端に同じく硬質合成樹脂材により形成した雌雄一対で互いに着脱可能に形成した接続具２０とにより構成してある。 As shown in FIGS. 1 and 3, the auxiliary belt 10 is made of a pair of belt portions 11a and 11b in which synthetic fiber materials are formed in a band shape, and a rigid composite in which one end of the belt portions is narrowly fixed to the backpack belt 3 of the school bag 1. It is composed of a mounting portion 13 formed of a resin material and a connector 20 formed on the other end of the belt portion by a pair of males and females also formed of a rigid synthetic resin material so as to be detachable from each other.

前記一対のベルト部１１ａ、１１ｂは、合成繊維素材を所定幅（１５ｍｍから３０ｍｍ、好ましくは、２０ｍｍ）に形成し、ベルト部１１ａの長さは、１３０ｍｍから１８０ｍｍ、好ましくは、１５０ｍｍに形成し、ベルト部１１ｂは、短尺な７０ミリから１２０ｍｍ、好ましくは、９０ｍｍの長さに形成してある。 The pair of belt portions 11a and 11b are formed of a synthetic fiber material having a predetermined width (15 mm to 30 mm, preferably 20 mm), and the length of the belt portion 11a is formed to be 130 mm to 180 mm, preferably 150 mm. The belt portion 11b is formed to have a short length of 70 mm to 120 mm, preferably 90 mm.

次いで、一方のベルト部１１ａには、一端に背負ベルト３に狭着する装着部１３を連結し、他方に該ベルト部の長さを調節する調節部２８を介して接続具２０の雌部片２５を連結し、他方にベルト部１１ｂには、一端に背負ベルト３に狭着する装着部１３を連結し、他方に接続具２０の雄部片２１を連結してある。 Next, a mounting portion 13 narrowly attached to the backpack belt 3 is connected to one end of the belt portion 11a, and a female portion piece of the connector 20 is connected to the other via an adjusting portion 28 for adjusting the length of the belt portion. 25 is connected, and a mounting portion 13 narrowly attached to the backpack belt 3 is connected to one end of the belt portion 11b, and a male portion 21 of the connector 20 is connected to the other end.

前記装着部１３は、図３〜５に示すごとく、硬質合成樹脂材からなり中央上下方向にベルト孔１６を形成し、前記装着部１３の一側にベルト部１１ａ、１１ｂの一端をそれぞれ連結する連結孔１８を設けてある。 As shown in FIGS. 3 to 5, the mounting portion 13 is made of a hard synthetic resin material and has a belt hole 16 formed in the vertical direction in the center, and one ends of the belt portions 11a and 11b are connected to one side of the mounting portion 13. A connecting hole 18 is provided.

前記装着部１３のベルト孔１６は、図４、５に示すごとく、上方開口部１６ａを背負いベルト３の肩ベルト部５を構成する胸部５ｂの横幅と厚さよりやや狭い横幅と厚さに開口し、下方開口部１６ｂは背負いベルト３のベルト連結部９が挿通可能な横幅と厚さに開口し、上下方向全体を逆末広がりに形成してある。 As shown in FIGS. The lower opening 16b is opened to have a width and a thickness that allows the belt connecting portion 9 of the backpack belt 3 to be inserted, and is formed so as to extend in the reverse direction as a whole in the vertical direction.

この装着部１３の背負いベルト３への取付けは、背負いベルト３のベルト連結部９の下端をベルト孔１６の上方開口部１６ａから挿通し、装着部１３を肩当部５方向に移動させ、前記ベルト孔１６の内壁面全体と前記肩当部５の胸部５ｂの外周面全体とが圧接して狭着させることにより、装着部１３を肩当部５の胸部５ａに支持固定可能に形成してある。 To attach the mounting portion 13 to the backpack belt 3, the lower end of the belt connecting portion 9 of the backpack belt 3 is inserted through the upper opening 16a of the belt hole 16, and the mounting portion 13 is moved in the shoulder rest portion 5 direction. The entire inner wall surface of the hole 16 and the entire outer peripheral surface of the chest portion 5b of the shoulder rest portion 5 are brought into close contact with each other to be narrowly fitted, so that the mounting portion 13 can be supported and fixed to the chest portion 5a of the shoulder rest portion 5.

また、図３に示すごとく、前記装着部１３の正面には表示部３５を設け、該表示部に例えば、自動車のライトに反射する反射板、または、各種のアニメのキャラクターを表記可能に形成することができる。さらには、この表示部３５を含む装着部全体を学童が興味を引く斬新なデザインなどにすることにより、ランドセルの購買意欲を増進させることもできる。 Further, as shown in FIG. 3, a display unit 35 is provided in front of the mounting unit 13, and for example, a reflector reflecting a light of an automobile or various animation characters can be formed on the display unit so as to be able to be written. be able to. Furthermore, by making the entire mounting part including the display part 35 a novel design that attracts the interest of school children, it is possible to increase the purchasing motivation of the school bag.

前記した補助ベルト１０に取付けた接続具２０は、図３、７に示すごとく、公知の連結具で、雌雄一対の雄部片２１と雌部片２５とからなり、装着部１３の連結孔１８にベルト部１１ａの一端を連結し、他端に該ベルト部の長さを調節する長さ調節部２８を介して雌部片２５を連結し、同じく装着部１３の連結孔１８に一端を連結したベルト部１１ｂの他端に雄部片２１を取付けてある。 As shown in FIGS. 3 and 7, the connecting tool 20 attached to the auxiliary belt 10 is a known connecting tool, which is composed of a pair of male and female male part pieces 21 and female part pieces 25, and is a connecting hole 18 of the mounting portion 13. One end of the belt portion 11a is connected to the other end, the female portion piece 25 is connected to the other end via the length adjusting portion 28 that adjusts the length of the belt portion, and one end is also connected to the connecting hole 18 of the mounting portion 13. A male portion 21 is attached to the other end of the belt portion 11b.

この接続具２０の連結は、雄部片２１の左右に設けた弾発力を有する係止爪部２３と、雌部片２５に設けた爪受部２６とを着脱可能に嵌合して連結する。 The connecting tool 20 is connected by detachably fitting and connecting the locking claw portion 23 having elastic force provided on the left and right of the male portion piece 21 and the claw receiving portion 26 provided on the female portion piece 25. do.

補助ベルト１０を背負いベルト３に取付ける場合、背負いベルト３は、ランドセル１の下面に取付けた下ベルト(図示せず)と連結する前に、背負いベルト３のベルト連結部９の先端を装着部１３の上方ベルト孔１６ａに挿通して肩当部５方向に移動させ、肩当部５の胸部５ｂ方向に摺動させて動かなくなる位置まで移動させて狭着固定する。 When the auxiliary belt 10 is attached to the backpack belt 3, the backpack belt 3 is attached to the tip of the belt connecting portion 9 of the backpack belt 3 before being connected to the lower belt (not shown) attached to the lower surface of the school bag 1. It is inserted through the upper belt hole 16a of the belt and moved in the direction of the shoulder rest 5, and then slid in the direction of the chest 5b of the shoulder rest 5 to move to a position where it cannot move and is narrowly fixed.

その際、装着部１３のベルト孔１６は、肩当部５の胸部５ｂの横幅と厚さよりやや狭く開口し、下方開口部１６ｂは背負いベルト３のベルト連結部９が挿通可能な横幅と厚さの逆末広がりに開口してある。そのため、この装着部１３を肩当部５の上方向に摺動させると、前記ベルト孔１６の内壁面全体と前記肩当部５の胸部５ｂの外周面全体とが面接触する摩擦抵抗により、装着部１３を肩当部５の胸部５ｂに支持固定させることができる。 At that time, the belt hole 16 of the mounting portion 13 opens slightly narrower than the width and thickness of the chest 5b of the shoulder rest portion 5, and the lower opening 16b has the width and thickness through which the belt connecting portion 9 of the backpack belt 3 can be inserted. It is open to the reverse end. Therefore, when the mounting portion 13 is slid upward on the shoulder rest portion 5, the mounting portion is due to frictional resistance in which the entire inner wall surface of the belt hole 16 and the entire outer peripheral surface of the chest portion 5b of the shoulder rest portion 5 are in surface contact with each other. 13 can be supported and fixed to the chest 5b of the shoulder rest 5.

ベルト孔１６の内径は肩当部５の胸部５ｂの横幅よりやや細幅に形成してあるため、装着部１３を肩当部５の下部まで移動させながら摺動させると、肩当部５の幅方向に設けたクッション部６を変形させながら摺動させて動かない位置まで上昇させて狭着固定させことができる。一度狭着固定させると摩擦抵抗によりランドセルの揺動や振動では容易に引く抜くことが困難になる。 Since the inner diameter of the belt hole 16 is formed to be slightly narrower than the lateral width of the chest portion 5b of the shoulder rest portion 5, when the mounting portion 13 is slid while moving to the lower portion of the shoulder rest portion 5, it is moved in the width direction of the shoulder rest portion 5. The provided cushion portion 6 can be slid while being deformed and raised to a position where it does not move, and can be fixed in a narrow position. Once fixed in a narrow space, it becomes difficult to pull it out easily due to the swing or vibration of the school bag due to frictional resistance.

図６に示す装着部１３のベルト孔１７は、内壁面全体に波形またはくさび形などの凹凸部１９を設けることにより、ベルト孔１７の内壁面全体と胸部５ｂの外周面全体との接触面積が広くなることから装着部１３の狭着力が増し、学童がランドセルを乱暴に取り扱っても衝撃で抜けるおそれがなく安心して使用することができる。 The belt hole 17 of the mounting portion 13 shown in FIG. 6 is provided with an uneven portion 19 such as a corrugated shape or a wedge shape on the entire inner wall surface, so that the contact area between the entire inner wall surface of the belt hole 17 and the entire outer peripheral surface of the chest 5b is increased. Since it becomes wider, the narrowing force of the mounting portion 13 increases, and even if a school child handles the school bag roughly, there is no risk of it coming off due to an impact, and the school bag can be used with confidence.

補助ベルト１０を背負いベルト３に装着後、ベルト部１１ａに設けた長さ調節部２８でランドセル１を背負う学童の肩幅に調整し、さらに接続具２０の雄部片２１と雌部片２５を互いに嵌合して連結する。この調節は、雄部片２１と雌部片２５を互いに連結した後に調節してもよいことは勿論である。 After attaching the auxiliary belt 10 to the backpack belt 3, the length adjusting portion 28 provided on the belt portion 11a adjusts the shoulder width of the school child carrying the school bag 1 on the back, and further, the male part piece 21 and the female part piece 25 of the connector 20 are attached to each other. Fit and connect. Of course, this adjustment may be made after connecting the male part 21 and the female part 25 to each other.

したがって、補助ベルト１０の長さを調節部２８で調節して背負いベルト３の肩幅を学童の肩幅に合わせることにより、背負いベルト３が幅方向に広がらず一定幅を維持するため、安定してランドセルを背負うことができる。また、この補助ベルト１０は、不使用時には、装着部１３を背負いベルト３の肩当部５から下方に押し下げて引き抜くことにより、自由に取り外して収納することができる。 Therefore, by adjusting the length of the auxiliary belt 10 with the adjusting portion 28 and adjusting the shoulder width of the backpack belt 3 to the shoulder width of the school child, the backpack belt 3 does not spread in the width direction and maintains a constant width, so that the school bag is stable. Can be carried on the back. Further, when not in use, the auxiliary belt 10 can be freely removed and stored by pushing the mounting portion 13 downward from the shoulder rest portion 5 of the belt 3 and pulling it out.

以下本考案の実施の形態の作用について説明すると、ランドセル１の背負いベルト３に補助ベルト１０を取付ける場合、背負いベルト３を構成するベルト連結部９の下端を装着部１３の上方開口部１６ａから挿入して下方開口部１６ｂに抜いて装着部１３を肩当部５方向に摺動させる。 Hereinafter, the operation of the embodiment of the present invention will be described. When the auxiliary belt 10 is attached to the backpack belt 3 of the school bag 1, the lower end of the belt connecting portion 9 constituting the backpack belt 3 is inserted from the upper opening 16a of the mounting portion 13. Then, it is pulled out to the lower opening 16b and the mounting portion 13 is slid in the shoulder rest portion 5 direction.

この装着部１３は、細幅のベルト連結部９から幅広になる肩当部５の下端まで移動を阻止されることなく上昇し、さらに上昇させると横幅が広くなる肩当部５の下方胸部５ｂに設けたクッション部６を変形させながら摺動して上昇し、ベルト孔１６の内壁面と胸部５ｂの外周面とが面接触し、摺動不可能位置で停止して狭着固定する。 The mounting portion 13 is provided on the lower chest 5b of the shoulder rest portion 5 which rises from the narrow belt connecting portion 9 to the lower end of the shoulder rest portion 5 which becomes wider without being blocked, and when further raised, the width becomes wider. The cushion portion 6 is deformed and slides up, and the inner wall surface of the belt hole 16 and the outer peripheral surface of the chest 5b come into surface contact with each other, and the cushion portion 6 is stopped at a non-sliding position to be fixed in a narrow position.

前記装着部１３の停止位置は、ベルト孔１６の内壁面全体が逆末広がりに形成され、前記肩当部５は胸部５ｂから肩部５ａ方向に幅広に形成してあるため、上方開口部１６ａが背当部５の肩部５ａの幅広部分に引っ掛かり上昇が阻止されて停止するため、装着部１３を肩当部５の胸部５ｂに支持固定させることができる。 As for the stop position of the mounting portion 13, the entire inner wall surface of the belt hole 16 is formed so as to extend in the opposite direction, and the shoulder rest portion 5 is formed wide from the chest 5b toward the shoulder 5a, so that the upper opening 16a is the back. Since the mounting portion 13 is stopped by being caught by the wide portion of the shoulder portion 5a of the shoulder rest portion 5 and stopped, the mounting portion 13 can be supported and fixed to the chest portion 5b of the shoulder rest portion 5.

さらに、ベルト部１１ａ、１１ｂの長さ調節は、ベルト部１１ａに取付けた長さ調節部２８でベルト部の長さを調節してランドセルを背負う学童の肩幅と背負いベルト３の左右幅を適正幅に調節し、次いで、接続具２０の雄部片２１と雌部片２５とを嵌合させて連結する。したがって、学童の胸元で適正な位置に補助ベルト１０を取付けることができるので、背負いベルト３が幅方向に広がるのを防止して快適にランドセルを背負うことができる。 Further, the length of the belt portions 11a and 11b is adjusted by adjusting the length of the belt portion with the length adjusting portion 28 attached to the belt portion 11a to adjust the shoulder width of the school bag carrying the school bag and the left and right width of the backpack belt 3 appropriately. Then, the male part piece 21 and the female part piece 25 of the connector 20 are fitted and connected to each other. Therefore, since the auxiliary belt 10 can be attached to an appropriate position on the chest of the school child, the backpack belt 3 can be prevented from spreading in the width direction and the school bag can be comfortably carried on the back.

前記装着部１３のベルト孔１７の内壁面全体に波形またはくさび形などの凹凸部１９を設けることにより、ベルト孔１７の内壁面全体と胸部５ｂの外周面全体との接触面積が広くなることから装着部１３の狭着力が増し、学童がランドセルを乱暴に取り扱っても衝撃や振動で抜けるおそれがなく安心して使用することができる。 By providing the uneven portion 19 such as a corrugated shape or a wedge shape on the entire inner wall surface of the belt hole 17 of the mounting portion 13, the contact area between the entire inner wall surface of the belt hole 17 and the entire outer peripheral surface of the chest 5b becomes wider. The narrowing force of the mounting portion 13 is increased, and even if a school child handles the school bag roughly, there is no risk of it coming off due to impact or vibration, and the school bag can be used with peace of mind.

さらにはまた、補助ベルト１０は、装着部１３の表面に設けた表示部３５に自転車や車両のライトに反射する反射板を取付けて学童の交通事故を防止でき、また、任意形状の図柄や人気漫画のキャラクターを表記して他のランドセルと差別化を図ることにより、ランドセルの所有者を明確にすることができ、さらにはまた、学童が補助ベルトに興味を持つことにより、ランドセルの購買意欲を増進させることができる。 Furthermore, the auxiliary belt 10 can prevent traffic accidents of school children by attaching a reflector that reflects the light of a bicycle or a vehicle to the display portion 35 provided on the surface of the mounting portion 13, and has an arbitrary shape and popularity. By noting the character of the cartoon and trying to differentiate it from other school bags, the owner of the school bag can be clarified, and further, the school bag's interest in the auxiliary belt makes the school bag motivated to buy. Can be promoted.

このベルト部１１ａ、１１ｂに取付けた接続具２０は、雄部片２１と雌部片２５とを互いにワンタッチで連結することにより、低学年の学童でも胸元で適正な位置に補助ベルト１０を取付けることがでるので疲れにくく快適に背負うことができる。さらには、背負いベルト３に補助ベルト１０を取付けることにより、背負いベルト３の肩部分での広がり防止してランドセルの左方向への揺れを防止し快適にランドセルを背負うことができる。 The connector 20 attached to the belt portions 11a and 11b connects the male portion 21 and the female portion 25 to each other with one touch, so that even a lower grade school child can attach the auxiliary belt 10 to an appropriate position on the chest. You can carry it comfortably on your back without getting tired. Further, by attaching the auxiliary belt 10 to the backpack belt 3, the backpack belt 3 can be comfortably carried on the back by preventing the school bag from spreading at the shoulder portion and preventing the school bag from swinging to the left.
