Description

本考案は、学童が背負うランドセルの背負いベルトが歩行中に肩からずり下がって開くのを防止する背負いベルトの改良に関する。 The present invention relates to an improvement of the backpack belt that prevents the backpack belt of the school bag carried by school children from slipping down from the shoulder and opening while walking.

従来、学童が使用するランドセルは、教科書やノートなどの副教材、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。さらに、昨今は教育現場においても文部科学省の新学習要領に示すごとく、2020年から情報教育・ICT活用教育が行われている。 Traditionally, school bags used by school children are quite heavy because they accommodate supplementary teaching materials such as textbooks and notebooks, as well as gymnastics equipment. Furthermore, in recent years, information education and ICT utilization education have been conducted since 2020, as shown in the new course of study of the Ministry of Education, Culture, Sports, Science and Technology.

そのため、学童は日常的にタブレット型端末やノートパソコンなどのディスプレイパネルを備えた板状の電子機器を使用して授業を受けることとなった。そのため、学童は重量(400gから700g)のある電子機器を収納したランドセルを登下校時に持ち運ぶため、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となる。 As a result, school children routinely take classes using plate-shaped electronic devices equipped with display panels such as tablet terminals and laptop computers. Therefore, school children carry a school bag containing heavy electronic devices (400 g to 700 g) when they go to and leave school, so it is a considerable burden for school children in the lower grades from 1st grade to 3rd grade to carry a heavy school bag on their backs. Will be.

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の長さ調節をすることが可能に形成してある。しかし、小柄な低学年の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、登下校の振動や揺れとランドセルの重量で背負いベルトの肩当部が広がり肩からずり落ちやすくなる。 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. However, if a small school child in the lower grades carries a heavy school bag on his back even if the backpack belt is adjusted, the shoulder rest of the backpack belt will expand due to the vibration and shaking of going to and from school and the weight of the school bag, and it will be easy to slip off the shoulder.

背負いベルトが肩からずり落ちて広がるとランドセルの重心が下方に移動しランドセルが背中から離れるため、低学年の学童にとってランドセルがより重くなって背負いにくくなる。さらには、背負いベルトが肩からずり下がって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疲れやすいだけでなく、いわゆる「ランドセル症候群」となりやすい。ランドセル症候群とは、自分の身体に合わない重さや大きさのランドセルを背負ったまま、長時間通学することによる心身の不調を表す言葉である。 When the backpack belt slides down from the shoulder and spreads, the center of gravity of the school bag moves downward and the school bag moves away from the back, which makes the school bag heavier and harder to carry for younger school children. Furthermore, walking with the backpack belt sliding down from the shoulder and spreading out not only makes it difficult for the school bag to sway from side to side and makes it difficult to walk, but also tends to cause so-called "school bag syndrome". School bag syndrome is a term that expresses physical and mental disorders caused by going to school for a long time while carrying a school bag of a weight and size that does not fit one's body.

さらにはまた、ランドセルが搖動することにより収納した教科書や副教材などが傷みやすいだけでなく、ランドセルに収納した電子機器の故障の原因となる虞があり、且つ、背負ったランドセルが安定しないと歩行中に身体が左右にブレて歩行が危険となる場合があるなどの多くの問題点を有している。 Furthermore, the textbooks and supplementary teaching materials stored in the school bag are easily damaged by the movement of the school bag, and there is a risk of causing a malfunction of the electronic devices stored in the school bag, and walking if the school bag carried on the back is not stable. It has many problems such as the body may shake from side to side and walking may be dangerous.

そのため、ランドセルの背負いベルトが肩からずれて広がるのを防止して快適に登下校するための補助具として肩ズレ防止具が使用され、背負いベルトの間に肩ズレ防止具を取付けてベルトの広がりを防止してランドセルを背負い易くしてある以下のものが知られている(例えば、特許文献1、2参照)。 Therefore, a shoulder slip prevention device is used as an auxiliary tool to prevent the backpack belt of the school bag from spreading off the shoulder and to go to and leave school comfortably, and a shoulder slip prevention device is attached between the backpack belts to spread the belt. The following are known that prevent the problem and make it easier to carry the school bag on the back (see, for example, Patent Documents 1 and 2).

しかし、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際、いずれもそれぞれベルト部の一端を背負いベルトの任意個所に巻きつけて装着し、簡単に取り外しができない構造である。そのため、使用中に連結ベルトがずり下がりお腹付近に位置し、連結ベルトとしての効果を発揮できない恐れがある。さらには、連結具のベルトを連結しないときには連結部分が下方に垂れ下がりぶらぶら状態になるため邪魔である。さらにはまた、垂れ下がったベルト部分がぶらぶらすると、歩行中に木の枝やすれ違う車両に引っ掛かる可能性が有り、非常に危険であるなどの問題点を有している。 However, when these connecting belts are attached to the backpack belt of the school bag, one end of each belt portion is wrapped around an arbitrary part of the backpack belt and attached, and the structure cannot be easily removed. Therefore, the connecting belt may slide down during use and be located near the abdomen, and may not be effective as a connecting belt. Furthermore, when the belt of the connecting tool is not connected, the connecting portion hangs down and becomes a hanging state, which is an obstacle. Furthermore, if the hanging belt portion hangs down, it may be caught by a tree branch or a vehicle passing by while walking, which is extremely dangerous.

そこで、本考案は、背負いベルトの裏面にいわゆるチェストベルト(肩ズレ防止具)を保持する保持部を設け、該保持部にチェストベルトの端部を取付けてチェストベルトを常に学童の正面(胸部分)側に位置させることにより、登下校中の揺動によるチェストベルトのずり下がりを防止することにより、ランドセルを常に背中側に位置させて学童が疲れずに安全に登下校することができるようにし、また、チェストベルトの不使用時には簡単に取り外して収納し紛失を防止することを目的とする。 Therefore, in the present invention, a holding portion for holding a so-called chest belt (shoulder slip prevention device) is provided on the back surface of the backpack belt, and the end portion of the chest belt is attached to the holding portion so that the chest belt is always in front of the school child (chest portion). By locating it on the) side, it prevents the chest belt from slipping down due to rocking while going to and from school, so that the school bag is always located on the back side so that school children can safely go to and leave school without getting tired. Also, when the chest belt is not in use, it can be easily removed and stored to prevent loss.

本考案は、ランドセルを構成する左右一対の背負いベルト2において、前記背負いベルト2の上端から230mmから280mmの間に肩当部3を形成し、該肩当部の上端から100mmから140mmの間に肩部5と、該肩部の下方100mmから140mの間にやや幅狭に形成した学童の胸部分に位置する正面胸部6を一体に形成し、該正面胸部の裏面に合成繊維生地または布帛により縦長で帯状に形成した保持帯部10の上下両端に設けた接続部12、12をそれぞれ縫着または鋲で固定し、一対のベルト部21、21からなるチェストベルト20のそれぞれ一端に設けた雌雄一対の装着部22、22を前記保持帯部10の中央に設けた連通部15から正面胸部6側に環回させて着脱可能に留め、前記ベルト部21、21の他端に設けた雌雄一対からなる連結部30を着脱可能に連結して背負ベルト2が幅方向に広がるのを規制してなることを特徴とする。また、前記背負いベルト2を構成する肩当部3は、上端から250mmの長さに形成し、該肩当部の上端から125mmに肩部5と、該肩部から下方125mにやや幅狭に形成した学童の胸部分に位置する正面胸部6をそれぞれ一体に形成してなることを特徴とする。さらには、前記チェストベルト20のベルト部21の一端に設けた装着部22は、一方の装着雄部23をベルト部21の一端側に取付け、他方の装着雌部25を前記ベルト部21の連結部寄りに取付けて互いに着脱可能に取付けてなることを特徴とする。さらにはまた、前記チェストベルト20のベルト部21に取付けた装着部22は、ホックまたは面ファスナからなることを特徴とする。また、前記チェストベルト20のベルト部21に取付けた連結部30は、一方のベルト部21に該ベルト部の長さを調節する調節部38を介して雌部片35を取付け、他方のベルト部21の端部に雄部片31を連結し、前記雄部片31と雌部片35を互いに着脱可能に連結してなることを特徴とする。 In the present invention, in the pair of left and right backpack belts 2 constituting the land cell, the shoulder support portion 3 is formed between 230 mm and 280 mm from the upper end of the backpack belt 2, and the shoulder portion is between 100 mm and 140 mm from the upper end of the shoulder support portion. 5 and the front chest 6 located in the chest of the school child formed slightly narrower between 100 mm and 140 m below the shoulder are integrally formed, and the back surface of the front chest is vertically elongated with a synthetic fiber cloth or cloth. A pair of males and females provided at one end of a chest belt 20 composed of a pair of belt portions 21 and 21 by fixing the connecting portions 12 and 12 provided at the upper and lower ends of the strip-shaped holding belt portion 10 with sewing or studs, respectively. The mounting portions 22 and 22 are circulated from the communication portion 15 provided in the center of the holding band portion 10 to the front chest 6 side to be detachably fastened, and consist of a pair of males and females provided at the other ends of the belt portions 21 and 21. The connecting portion 30 is detachably connected to prevent the backpack belt 2 from spreading in the width direction. Further, the shoulder rest portion 3 constituting the backrest belt 2 is formed to have a length of 250 mm from the upper end, and is formed to be 125 mm from the upper end of the shoulder rest portion with the shoulder portion 5 and slightly narrower with the shoulder portion 125 m below. It is characterized in that the front chest 6 located on the chest of a school child is integrally formed. Further, in the mounting portion 22 provided at one end of the belt portion 21 of the chest belt 20, one mounting male portion 23 is mounted on one end side of the belt portion 21, and the other mounting female portion 25 is connected to the belt portion 21. It is characterized in that it is attached to a part and is detachably attached to each other.

したがって、通学中の学童の揺動や駆けっこなどによる揺動でもチェストベルト20は、保持帯部10に幅方向を保持されるため所定位置から下がらることなく背負いベルト2、2の横幅を一定幅に支持するため横幅の広がりを防止することができる。 Therefore, the chest belt 20 is held in the width direction by the holding belt portion 10 even when the schoolchild is swinging while commuting to school or swinging due to running, so that the width of the backpack belts 2 and 2 is constant without lowering from a predetermined position. Since it supports the width, it is possible to prevent the width from expanding.

さらには、前記したごとく、背負いベルト2、2の肩当部3、3が肩から下がらないのでランドセルの上方が背中側から離れることなく背中側に位置し、ランドセルの重心が学童の背中側に位置するため背負いやすく肩こりや痛みいわゆる、「ランドセル症候群」を防止して快適に歩行することができる。 Furthermore, as described above, since the shoulder pads 3 and 3 of the backpack belts 2 and 2 do not fall from the shoulders, the upper part of the school bag is located on the back side without separating from the back side, and the center of gravity of the school bag is located on the back side of the school child. Therefore, it is easy to carry on your back, and you can prevent stiff shoulders and pain, so-called "school bag syndrome", and walk comfortably.

また、背負いベルト2の肩当部3の正面胸部6の裏面に縦長に設けた保持帯部10へのチェストベルト20の取付けは、保持帯部10の連通部15にチェストベルト20のベルト部21の一端をそれぞれ挿通して正面胸部6の表面側から環回させてベルト部21の装着雄部23と装着雌部25を接合させるだけの簡単な操作で取付けることができる。 Further, when the chest belt 20 is attached to the holding band portion 10 vertically provided on the back surface of the front chest portion 6 of the shoulder rest portion 3 of the back carrying belt 2, the belt portion 21 of the chest belt 20 is attached to the communication portion 15 of the holding belt portion 10. It can be attached by a simple operation of inserting one end thereof and rotating the belt portion 6 from the surface side of the front chest portion 6 to join the attached male portion 23 and the attached female portion 25 of the belt portion 21.

前記チェストベルト20を背負いベルト2に装着した後、互いの連結部30を連結し、ベルト部21の長さを調節部38で適正な肩幅の長さに調整することができる。したがって、前記したごとく、互いの背負いベルト2、2の間が幅方向に広がらないので肩当部が肩からずれるのを防止することができ、且つ、登下校時において学童が安定してランドセルを背負うことができる。 After the chest belt 20 is attached to the backpack belt 2, the connecting portions 30 can be connected to each other, and the length of the belt portion 21 can be adjusted to an appropriate shoulder width by the adjusting portion 38. Therefore, as described above, since the space between the backpack belts 2 and 2 does not widen in the width direction, it is possible to prevent the shoulder rest from shifting from the shoulder, and the schoolchild can stably carry the school bag on his / her back when going to and from school. be able to.

このチェストベルト20の不使用時は、ベルト部21の装着部22を互いに離脱させた後、ベルト部21を保持帯部10の連通部15から引き抜くことにより、簡単に取り外して収納することができるので紛失を防止でき便利であると共に、不使用時におけるベルト部21のぶら下がりによる不慮の事故を防止することができる。 When the chest belt 20 is not in use, the belt portion 21 can be easily removed and stored by separating the mounting portions 22 of the belt portions 21 from each other and then pulling out the belt portion 21 from the communication portion 15 of the holding band portion 10. Therefore, it is possible to prevent the loss and it is convenient, and it is possible to prevent an accidental accident due to the hanging of the belt portion 21 when not in use.
