On the other hand, when releasing the fixation, as shown in FIG. 4B, an operation completely opposite to that in FIG. 4A is performed, and the engagement of the backrest latch hook 42 is released along the direction of the arrow. As shown in FIGS. 6A and 6B, the backrest rotation locking bar 44 is engaged (inserted) into the first positioning hole 10 and then rotated, and in the illustrated situation, from the horizontal direction to the vertical direction along the direction of the arrow. However, as long as the backrest can be locked (fixed) to the first seat portion 1, it is not limited to the illustrated rotatable rotation locking bar 44. For example, the backrest main body 41 can be fixed to the first seat surface part 1 by simply engaging (inserting) the backrest rotation locking bar 44 into the first positioning hole 10 without rotating the backrest rotation locking bar 44. Good too.
第１実施形態に係る椅子は上下反転可能なことにより年齢の異なる児童のニーズを満たすことができ、背もたれ４を第１座面部１または第２座面部２に対応して係止することもできる。背もたれ４と第２座面部２との係止形態は、背もたれ４と第１座面部１との係止形態と類似するため、ここでその説明を省略する。 Since the chair according to the first embodiment can be turned upside down, it can meet the needs of children of different ages, and the backrest 4 can also be locked in correspondence with the first seat part 1 or the second seat part 2. . The manner in which the backrest 4 and the second seat portion 2 are engaged is similar to the manner in which the backrest 4 and the first seat portion 1 are engaged, and therefore the description thereof will be omitted here.
７ヶ月～６歳（７２ヶ月）の児童に対しては、第１実施形態に係る椅子は以下通りの形態（表１）で様々なニーズを満たすことができる。 For children aged 7 months to 6 years (72 months), the chair according to the first embodiment can meet various needs in the following configurations (Table 1).
このように、７ヶ月～１歳の児童に対しては、椅子が反転しないことにより低い座面（ｈ１＞ｈ２）を保持し、児童の年齢が低くて背もたれ４の使用が必要となる。１歳～３歳の児童に対しては、１歳未満の時に比べて成長してきたので、椅子を反転させることにより高い座面（ｈ１＞ｈ２）を保持し、児童の年齢が低くて背もたれ４の使用がまだ必要となる。３歳～６歳の児童に対しては、椅子を反転させることにより高い座面（ｈ１＞ｈ２）を保持し、児童の年齢は快適さに応じて背もたれを適切に使用可能な年齢である。ここでは、高さｈ１は、１７０～２００ｍｍであることが好ましく、１８０ｍｍであることがより好ましく、高さｈ２は、１４０～１６０ｍｍであることが好ましく、１５０ｍｍであることがより好ましい。こうすることで、乳幼児は抵抗なく自然かつ快適に椅子に座り、幼い頃から良い座り姿勢を身に付けることができる。椅子自体の占有床面積が十分であって安定かつ安全である。背もたれが乳幼児の背中をよりよく支え、取り外し可能であって高い位置と低い位置のいずれにも取り付けて使用可能である。乳幼児は椅子に座る場合に椅子の高さが適切であるため、膝が自然に曲がって足が床面に着床する。 In this way, for children between 7 months and 1 year old, the chair does not invert so that a low seating surface (h1>h2) is maintained, and the use of the backrest 4 is necessary because the children are young. For children between 1 and 3 years old, since they have grown compared to when they were under 1 year old, the chair can be inverted to maintain a high seat surface (h1>h2), and if the child is younger, the backrest should be 4 The use of is still required. For children between the ages of 3 and 6, the chair is inverted to maintain a high seating surface (h1>h2), and the child is old enough to use the backrest appropriately depending on comfort. Here, the height h1 is preferably 170 to 200 mm, more preferably 180 mm, and the height h2 is preferably 140 to 160 mm, more preferably 150 mm. This allows infants to sit naturally and comfortably on the chair without resistance, allowing them to learn good sitting posture from an early age. The chair itself occupies sufficient floor space and is stable and safe. The backrest provides better support for the baby's back and is removable so that it can be mounted in either a high or low position. When infants sit on a chair, the height of the chair is appropriate, so their knees naturally bend and their feet touch the floor.
また、現代の家庭環境に自然に溶け込めるために、椅子の色はグレー、ライトグレー、オレンジ、ブルー、イエロー、ピンクのいずれかであることが好ましい。当然ながら、椅子については、他の適切な色を選んで使用してもよい。椅子全体の軽量化を実現するために、背もたれを含めて椅子全体の材質としては、環境配慮型プラスチックを用いることが好ましい。 Furthermore, in order to blend naturally into modern home environments, the chair's color is preferably gray, light gray, orange, blue, yellow, or pink. Of course, other suitable colors may be used for the chairs. In order to reduce the weight of the entire chair, it is preferable to use environmentally friendly plastic as the material for the entire chair including the backrest.
なお、図７Ａ～図７Ｃ及び図８Ａ～図８Ｃに示すように、椅子の本体部分は、円弧凹状に形成されることが好ましく、耐荷重性に優れ、安定かつ安全であるため、背もたれが固定されるかどうかにかかわらず、水平方向または垂直方向に複数の椅子を容易に積み重ねて収納することができ、収納スペースが小さく、幼稚園や遊び場などの公共場所に適用できる。 As shown in Figures 7A to 7C and Figures 8A to 8C, the main body of the chair is preferably formed into an arcuate concave shape, which has excellent load resistance, stability, and safety, so that the backrest is fixed. Regardless of whether it is installed, multiple chairs can be easily stacked horizontally or vertically, the storage space is small, and it can be applied to public places such as kindergartens and playgrounds.
図示された例において、第１座面部１及び第２座面部２は、前端部のみにおいて、連結部３を介して互いに連結されている。第１座面部１及び第２座面部２の間の空間は、両側方に開口し且つ後方にも開口している。第１座面部１及び第２座面部２の間の空間の上下方向への長さは、前側から後側に向けて、しだいに長くなる。したがって、一つの椅子の第１座面部１及び第２座面部２の間に、当該第１座面部１及び第２座面部２の後方から、他の椅子の連結部３を挿入することによって、他の椅子の連結部、第１座面部１及び第２座面部２が、一つの椅子の第１座面部１及び第２座面部２の間に配置されるようにして、図７Ａ～図８Ｃに示すように、一つの椅子及び他の椅子を重ねることができる。 In the illustrated example, the first seat part 1 and the second seat part 2 are connected to each other via a connecting part 3 only at the front end. The space between the first seat part 1 and the second seat part 2 is open to both sides and also to the rear. The vertical length of the space between the first seat part 1 and the second seat part 2 gradually increases from the front side to the rear side. Therefore, by inserting the connecting part 3 of another chair between the first seat part 1 and the second seat part 2 of one chair from the rear of the first seat part 1 and the second seat part 2, 7A to 8C, so that the connecting part, the first seat part 1, and the second seat part 2 of the other chair are arranged between the first seat part 1 and the second seat part 2 of one chair. One chair and another chair can be stacked on top of each other, as shown in .
図示された例において、一対の側板部５の側方向（横方向）への間隔は、前側から後側に向けて、しだいに狭くなる。すなわち、一対の側板部５の側方向への間隔は、前端部において、後端部よりも、広くなっている。したがって、一つの椅子の第１座面部１及び第２座面部２の間に、当該第１座面部１及び第２座面部２の後方から、他の椅子の連結部３を挿入する際、他の椅子の一対の側板間に、一つの椅子の後端部が位置するようになる。つまり、他の椅子の一対の側板間に一つの椅子の後端部を挿入することによって、他の椅子の一対の側板間に、一つの椅子の一対の側板部５、第１座面部１及び第２座面部２が配置されるようにして、図７Ａ～８Ｃに示すように、一つの椅子及び他の椅子を重ねることができる。 In the illustrated example, the distance between the pair of side plate portions 5 in the lateral direction (horizontal direction) gradually becomes narrower from the front side to the rear side. That is, the distance between the pair of side plate portions 5 in the lateral direction is wider at the front end than at the rear end. Therefore, when inserting the connecting part 3 of another chair between the first seat part 1 and the second seat part 2 of one chair from the rear of the first seat part 1 and the second seat part 2, The rear end of one chair is located between the pair of side plates of the chair. That is, by inserting the rear end of one chair between the pair of side plates of the other chair, the pair of side plates 5, the first seat part 1 and With the second seat portion 2 arranged, one chair and another chair can be stacked on top of each other, as shown in FIGS. 7A to 8C.
上述したように、第１実施形態に係る椅子によれば、従来技術に比べて、児童の成長につれても適用し続けることができ、７ヶ月～６歳の児童は必要に応じて適切な形態でニーズを満たすことができるとともに、背もたれが係合により固定されるので、露出する部品と危険な隙間がなく、児童の安全を危険にさらすことなく、収納が容易でかつ家庭環境に自然に溶け込む。 As described above, the chair according to the first embodiment can be continued to be used as the child grows, compared to the conventional technology, and children between 7 months and 6 years old can use the chair in an appropriate form as needed. In addition to meeting the needs, since the backrest is fixed by engagement, there are no exposed parts and dangerous gaps, without endangering the safety of children, easy to store, and blends naturally into the home environment.
