【発明の属する技術分野】
本発明は、ベビー用チェアに係り、さらに詳しくは乳幼児の浴室におけるバスチェアと居室における座椅子とに利用できる兼用型のベビー用チェアに関するものである。
【0002】
【従来の技術】
この種のベビー用チェアとして登録実用新案第3035733号公報に記載の「幼児入浴用補助いす」が知られている。上記公報記載の図面の一部が、図10に示されている。図10において、101は座盤、105は軸支部、111はU字形状の背凭れ部材、114は立上り部、122は保護アームである。上記の座盤101の左右両側辺部における前寄り箇所に左右の軸支部105が設けられ、この左右軸支部105に座盤101の上方に配された背凭れ部材111の左右両端が起伏可能として軸受けされている。そして、その明細書には背凭れ部材111を倒して小さい状態にして、搬送・格納に際する箱詰めをコンパクトにできる等の実用的効果を有すると言う説明がなされている。
【0003】
【発明が解決しようとする課題】
図10の従来の浴用補助いすの背凭れ部材111は、上記のように左右両端が軸支部105に起伏可能として軸受けされている。しかしながら、背凭れ部材111を伏臥したときにはU字形状内に立上り部114が格納されるので、幼児の椅子の利用が背凭れ部111の起立したときに限られることになる。したがって、浴室内で幼児をいすに座らせて洗髪するときは頭部を立てた状態で洗わなければならず、シャンプーが幼児の両目に流れ込むという不都合がある。このほか、図に示すように、いすの前面に傾斜取付けされるおもちゃを付けた保護アーム122だけが準備されているので、授乳時のほ乳瓶等を載せて居室用として兼用したときのベビー用のチェアとしては不適当になる等の問題点がある。
【0004】
本発明は、上記のような従来の課題を解決するためになされもので、背凭れ部材の上向きの度合いを容易に変更して、乳幼児の洗髪と睡眠に適する背凭れ角度に選択することができて、浴室は勿論のこと居室における幼児用の座椅子としても利用できる等の取り扱いに便利なベビー用チェアを実現することを目的としたものである。
【0005】
【課題を解決するための手段】
本発明は、装着部突設させて、座面を挟んだ対称的な左右一対の平行な側壁を形成した台座と、台座における左右の側壁に設けられた背凭れ部材と、装着部に着脱自在に装着されて左右の側壁を橋絡する橋絡部材とを備えたベビー用チェアであって、装着部は、側面視において上部が開口したコ字形に形成され、装着部の内面には、前後に形成された孔が対向して設けられ、橋絡部材の両端部には、ストッパー機構を内蔵した挿入部が設けられ、ストッパー機構は、挿入部の表面から互いに反対方向に突出して設けられた押し釦と、挿入部の表面から没入可能となるように表面から突出して設けられ、装着部の孔に挿入される一対のストッパー軸とを備え、橋絡部材を、一方のストッパー機構の両方の押し釦を押してこのストッパー機構のストッパー軸を没入させながら、他方のストッパー機構のストッパー軸を軸に回転して持ち上げ可能にしたベビー用チェアを構成したものである。
また、上記において、ストッパー機構が、挿入部の内部に背中合わせに配置され、押し釦及びストッパー軸が設けられた一対のストッパー板と、これらストッパー板の間に設けられ、これらストッパー板の間に拡張力を加えるバネとを備えたベビー用チェアを構成したものである。
また、上記において、装着部に装着される挿入部が同一構造で異なる機能を付設した複数の橋絡部材を構成し、該複数の橋絡部材を交換可能に構成したベビー用チェアを構成したものである。
また、上記において、一対の台座には、装着部の後方に連結部が突設されており、背凭れ部材は、台座における左右の側壁に設けられた軸支部を支点として頸当部側が揺動可能となっており、連結部における台座と背凭れ部材との相互間に設けられた連結機構により背凭れ部材の背凭れ角を可変にしたベビー用チェアを構成したものである。
【0006】
【発明の実施の形態】
実施の形態1
図1は本発明の実施の形態1の全体構成を示す斜視図、図2は実施の形態1の台座の説明図で、(a)は平面図、(b)は右側面図、(c)は前面図、図3は実施の形態1の断面説明図で、(a)はA−A断面図、(b)はB−B断面図、で、(c)は軸支部の断面図である。図2(a)と(c)は表裏の半分割図で示されている。
【0007】
以下、対称構造で一対型の構成部材については、数値符号の複数の記載を省略して説明する。
図1において、1はベビー用チェアである。ベビー用チェア1は合成樹脂により左右がほぼ対称構造に成形されている。ベビー用チェア1は平面形状がほぼ長方形で主に基盤の機能を司る台座2と、チェア内に収容された乳幼児の背中側を包囲する背凭れ部4と、座った乳幼児の上体部付近の移動範囲を規制する機能を果たす橋絡桿6との3部分から構成されている。
【0008】
台座2の構造を示す図2と図3において、21は台座2の中央前部に設けられた***部、22はその後方に続いて浅い扁平な凹部で構成された方形のシート部である。***部21に続くシート部22により、前方への乳幼児の滑り出しを防止した座面20が構成される。23と24はシート部22の周辺部に形成された複数の細溝と庇片である。細溝23と庇片24にはシート部22と相似形に作られたウレタン等からなるシート部材25(図1)の突出部と辺部等が差し込まれて、シート部材25がシート部22の凹部内に交換可能に添着される。26は台座2の底面四隅に設けられたウレタン樹脂等の滑り止め35(図9)が挿入される溝孔である。
【0009】
28は台座2の上面で座面20を挟み、一対の平行な左右対称的な側壁である。29は両側壁28の前方上端に突設され後で説明する橋絡桿6を装着するための装着部、30は後方側に突設されて背凭れ部材4に連結される円弧状の連結部、31は側壁28の中央寄りに形成された円筒状の軸支部である。装着部29はコ字形に形成され、内面に後述するストッパー軸が挿入される孔29aが対向して設けられている。連結部30の円弧面は軸支部31と同心的になっていて、鍵形の2つのロック穴32がその円弧面に開口している。また、33は軸支部30内の2つの係止孔、34は台座2の側面に傾斜して形成された背凭れ部4の下限の位置決め用の段部である。
【0010】
図4は背凭れ部材の説明図、図5はロック機構の説明図である。4は背凭れ部材で、輪郭形状が逆U字状に形成されている。41と42は背凭れ部材4の頸当部と背当部、43は両脇に突設された肘掛け部、44は下端の両側面に穿設された軸孔、45は2本の係止爪46を向かい合わせて設けたキャップである〔図3(c)〕。軸孔44は台座2側の軸支部31に嵌め合わされて、キャップ45が被されて背凭れ部材4の頸当部41側が軸支部31を中心に揺動可能に結合される。その際、キャップ45の2本の係止爪46が係止孔33に係止されて、抜け止めされる。47は断面がコ字形で背面側に開口し背凭れ部材4の輪郭に沿って設けられたU字溝、48はU字溝47内に設けられた背凭れ部材4をロックするロック部材を取り付けるための取付台である。
【0011】
取付台48はU字溝47内の左右に同一高さに形成され、この取付台48には連結部30に対応するロック機構50が設けられている。52はロック機構50の固定用のネジ、53は操作桿、54は摘み板、55はバネである。バネ55は操作桿53に拡張力を与えて、図5の(b)に示す状態で操作桿53の角部56をロック孔32に嵌入させて、背凭れ部材4の傾斜状態をロックする。
【0012】
また、橋絡桿6の部分的な構造が、図6(a),(b)に示されている。この橋絡桿6は対称型の上下2部材をネジ結合して構成され、コ字形の両端部を下方に折り曲げて端部に挿入部60が構成されている。70は挿入部60に内蔵されたストッパー機構である。71は挿入部60の内部に背中合わせに配置された一対のストッパー板、72は押し釦、73はストッパー軸、74はバネである。バネ74は両側の押し釦72の間に配置されて、ストッパー板71に拡張力を加えている。そして、押し釦72を矢印のように左右から押し付けると、ストッパー軸73の間隔が狭められて挿入部60の表面から没入する。62は橋絡桿6の上面に取り付けられた3種類の玩具類である。玩具類62のうち、左端は音を発しながら上下動する円筒玩具、中央は円筒面を露出させた手回し玩具、右端は星の外周を摘んで回転させる星形玩具である。なお、図1と図2(c)の83は実施の形態2の保持板82を保持する保持穴である。
【0013】
上記のような構成のベビー用チェア1は、それぞれ上述したような構造の台座2と背凭れ部材4と橋絡桿6との3部材を組み付けて構成される。即ち、背凭れ部材4を台座2の後部側に上から宛いながら台座2下部の外側面に露出した軸支部31に背凭れ部材4の軸孔44を嵌合して、外側からキャップ45を被せて両者を結合する。次いで、台座2のコ字型の装着部29に橋絡桿6の両端の挿入部60を挿入して側壁28間を橋絡すれば、図1に示すようなベビーチェア1が組み立てられる。
【0014】
組み立てられたベビーチェア1は乳幼児を入浴させるときに、浴室に運ばれて浴槽に近い床面に置かれる。通常状態ではロック機構50の角部56が上方のロック孔32に嵌入していて背凭れ角θ〔図9(b)〕がほぼ120度に設定されている。乳幼児をベビーチェア1に座らせるときは、予め橋絡桿6を解放させておく。橋絡桿6を解放するときは、図7(a)のゴシックの矢印で示されたように、橋絡桿6の一方(向かって左側)のストッパー機構70の押し釦72を親指と人差し指で押しながら、他方(右側)の挿入部60内のストッパー軸73を軸に回転して持ち上げる。
【0015】
そして、浴槽から抱き上げた乳幼児を座面20に座らせて、橋絡桿6を逆方向に回転して左の挿入部60を装着部29に嵌入して橋絡する〔図(b)〕。その際、ストッパー機構70のロック動作の有無を確認する。乳幼児をベビーチェア1から出して抱き上げるときも、上記と同様に橋絡桿6の橋絡状態を解放する。橋絡桿6を逆方向に回転してもよく〔図(c)〕、両側の押し釦72を同時に押して橋絡桿6を取り外してから座らせることもできる。
【0016】
また、乳幼児の洗髪を行うときは、図8(a)に示すように、ベビーチェア1の背面に向かって背凭れ部材4の背面の両側を両手で支える。そして、ロック機構50の摘み板54に両手の人差し指を掛けて引き上げると、操作桿53の角部56がロック孔32から抜け出してロックが解除される。そのまま、背凭れ部材4を押し下げれば、凭れ部材4のU字溝47の外壁が台座2の段部34に当接して背凭れ角θが下限の20度程度に押し下げられる。傾きが低くなるので、両目に流れ込むシャンプーに気を使うことなく、乳幼児の洗髪を行うことができる。操作桿53の角部56を2番目のロック孔32に嵌入すれば背凭れ角θがほぼ60度になり、成長した幼児の洗髪等に適用できる。
【0017】
このほか、台座2の内面側から操作して、図3(c)に示したキャップ45の2本の向かい合った係止爪46を外側に広げて外側方向の力を加えれば、キャップ45が押し出される。こうして、2つのキャップ45を抜き外せば、台座2から背凭れ部材4を分離することができる。また、前記のように橋絡桿6も分解できるので、これらの分離された3個の構成部材を小型な段ボール箱等にコンパクトに収納することも可能である。
【0018】
実施の形態2
図9は本発明の実施の形態2の構成を示す説明図で、(a)は側面図、(b)は(a)の断面図である。実施の形態2が座面20の前面上部に橋絡部材を設けて、チェアに収容された乳幼児の移動範囲を規制するという主たる機能においては変わるところがない。しかしながら、橋絡桿6に玩具類62を設けた構成の実施の形態1に対して、実施の形態2では橋絡部材6にテーブル8を設けた構造になっている。
【0019】
図9において、8はテーブル、81はその基部、82はテーブル8を支える保持板である。上記テーブル8の基部81にも、前記の橋絡桿6の挿入部60と同一構造の挿入部60が設けられている。保持板82はテーブル8に着脱自在で、必要により取り付けられる。そして、ベビーチェア1は浴室のほかに居室にも設置されて、授乳時やおやつ時には実施形態2のテーブル付きの橋絡部材6に取り替えられる。また、乳幼児の睡眠時には、ロック機構50を切り換えて背凭れ角θが60度や20度に選択されるようになっている。なお、図9の35は台座2の四隅に設けた滑り止めである。
【0020】
なお、上述の実施の形態では、星形等の玩具類を付設した橋絡桿とテーブルを付設した橋絡部材を交換可能に構成した場合を例示して説明したが、数学的な知能を発展させる玩具や電子技術の応用玩具等を設けた場合にも本発明を適用することができる。また、操作桿の角部をロック孔に嵌入させたロック機構を、実施の形態2の保持板のような支え部材で背凭れ角θを切り替えるように構成してもよい。特に、台座と背凭れ部材との連結部に摩擦車や歯車等を応用したロック手段付きの連結機構を構成して、背凭れ角θの間欠切換に代えて連続可変型にしてもよい。さらに、一対の出没するストッパー軸を設けたストッパー機構等の構成についても、必ずしも実施の形態の構造に限定するものではない。
【0021】
【発明の効果】
以上、説明したように、本発明は、背凭れ部材の背凭れ角を複数段に切り換え可能に構成した。したがって、浴室の洗髪時において、シャンプーの流入による乳幼児の目の痛みを防ぐことができる。また、居室内の乳幼児の食事や睡眠などの生活態様に合わせて、背凭れ角を適切な角度に設定することもできる。しかも、おもちゃやテーブル付きの橋絡部材を交換できるので、極めて便利になる。
【0022】
よって、本発明によれば、乳幼児の生活に即した姿勢で座らせることができるばかりか、座席時の状態に適した構成部材を選択的に構成できるベビー用チェアを提供することができ、極めて便利なベビー用チェアが実現される。

In a normal state, the corner portion 56 of the lock mechanism 50 is fitted into the upper lock hole 32, and the backrest angle θ (FIG. 9B) is set to approximately 120 degrees. When the infant is seated on the baby chair 1, the bridge 6 is released in advance. When releasing the bridge 6, the push button 72 of the stopper mechanism 70 on one side (toward the left side) of the bridge 6 is pushed with the thumb and forefinger as shown by the Gothic arrow in FIG. While pushing, the stopper shaft 73 in the other insertion portion 60 (the right side) is rotated about the shaft and lifted.
[0015]
Then, the infant hung up from the bathtub is seated on the seating surface 20, and the bridge 6 is rotated in the reverse direction so that the left insertion part 60 is fitted into the mounting part 29 and is bridged (FIG. (B)). At that time, the presence or absence of the locking operation of the stopper mechanism 70 is confirmed. When the baby is taken out from the baby chair 1 and lifted, the bridge state of the bridge 6 is released as described above. The bridge 6 may be rotated in the opposite direction (FIG. (C)), and the pushbuttons 72 on both sides can be pressed simultaneously to remove the bridge 6 and be seated.
[0016]
Further, when washing an infant's hair, both sides of the back of the backrest member 4 are supported with both hands toward the back of the baby chair 1 as shown in FIG. When the index finger of both hands is put on the knob plate 54 of the lock mechanism 50 and pulled up, the corner portion 56 of the operating rod 53 comes out of the lock hole 32 and the lock is released. If the backrest member 4 is pushed down as it is, the outer wall of the U-shaped groove 47 of the baffle member 4 comes into contact with the step portion 34 of the pedestal 2 and the backrest angle θ is pushed down to the lower limit of about 20 degrees. Since the inclination is low, infants can be washed without worrying about the shampoo flowing into their eyes. If the corner portion 56 of the operation rod 53 is fitted into the second lock hole 32, the backrest angle θ becomes approximately 60 degrees, which can be applied to hair washing of a grown infant.
[0017]
In addition, by operating from the inner surface side of the pedestal 2 and spreading the two opposing locking claws 46 of the cap 45 shown in FIG. 3 (c) outward and applying an outward force, the cap 45 is pushed out. It is. In this way, the backrest member 4 can be separated from the base 2 by removing the two caps 45. In addition, since the bridge 6 can be disassembled as described above, these three separated components can be stored compactly in a small cardboard box or the like.
[0018]
Embodiment 2
9A and 9B are explanatory views showing the configuration of the second embodiment of the present invention. FIG. 9A is a side view, and FIG. 9B is a cross-sectional view of FIG. There is no difference in the main function of the second embodiment in which a bridging member is provided at the upper front portion of the seating surface 20 and the movement range of the infant accommodated in the chair is restricted. However, in contrast to the first embodiment in which the toy 62 is provided on the bridge 6, the second embodiment has a structure in which the table 8 is provided on the bridge member 6.
[0019]
In FIG. 9, 8 is a table, 81 is a base portion thereof, and 82 is a holding plate that supports the table 8. The base portion 81 of the table 8 is also provided with an insertion portion 60 having the same structure as the insertion portion 60 of the bridge 6. The holding plate 82 is detachable from the table 8 and is attached if necessary. The baby chair 1 is installed in the living room in addition to the bathroom, and is replaced with the bridging member 6 with the table of the second embodiment at the time of breastfeeding or snacks. Further, when the infant sleeps, the backrest angle θ is selected to be 60 degrees or 20 degrees by switching the lock mechanism 50. In addition, 35 of FIG. 9 is a slip stopper provided at the four corners of the base 2.
[0020]
In the above-described embodiment, a case has been described in which the bridge member provided with toys such as a star shape and the bridge member provided with a table are configured to be replaceable, but mathematical intelligence has been developed. The present invention can also be applied when a toy or an applied toy of electronic technology is provided. In addition, the lock mechanism in which the corner portion of the operating rod is fitted in the lock hole may be configured to switch the backrest angle θ with a support member such as the holding plate of the second embodiment. In particular, a connecting mechanism with a lock means using a friction wheel, a gear, or the like may be configured at the connecting portion between the pedestal and the backrest member, and the continuously variable type may be used instead of the intermittent switching of the backrest angle θ. Furthermore, the configuration of a stopper mechanism or the like provided with a pair of protruding and retracting stopper shafts is not necessarily limited to the structure of the embodiment.
[0021]
【The invention's effect】
As described above, the present invention is configured such that the backrest angle of the backrest member can be switched to a plurality of stages. Therefore, it is possible to prevent infants' eye pain due to inflow of shampoo when washing hair in the bathroom. In addition, the backrest angle can be set to an appropriate angle in accordance with a lifestyle such as meals and sleep of infants in the room. Moreover, since the toy and the bridging member with the table can be exchanged, it becomes extremely convenient.
[0022]
Therefore, according to the present invention, it is possible to provide a baby chair that can be seated in a posture suited to the life of an infant and that can selectively configure components suitable for the state at the time of the seat. A convenient baby chair is realized.
