Description

【０００１】
【発明の属する技術分野】
本発明は、誰でも手軽に且つ適切にマッサージを受けられるようにする背中マッサージ部付枕に関する。
【０００２】
【従来の技術】
人の身体の各部分に対し所定のマッサージ効果を与えるマッサージ器は、手に持って使う小さなものから椅子状、マット状などの大きいものまで様々な形状のものが従来から用いられ、また、マッサージ動作機構にも機械的に動きを発生させる方式や空気による容器の膨張・収縮を用いる方式など、多様な方式が採用されている。
【０００３】
こうした従来のマッサージ器のうち、マット上に仰向けで寝た状態の人に対しマッサージ効果を与えるエアマットタイプのものは、身体の多くの箇所に同時にマッサージ効果を与えることができると共に、機械式に比べると軽量であり、非使用時には折畳んで容易に持運べ、収納にも便利であるという特長を有し、従来から広く用いられてきた。このようなエアマットタイプのマッサージ器の一例を図１０に示す。図１０は従来のマッサージ器の斜視図である。
【０００４】
前記図１０に示す従来のマッサージ器１００は、中空体のマット１０１と、このマット１０１内部に収納されて空気の注入、排出で膨張・収縮する複数の空気セル１０２と、この空気セル１０２に対し空気の加圧注入、吸引排出を行う空気注入排出装置１０３とを備える構成である。
この従来のマッサージ器１００では、人がマット１０１上に仰向けに寝た状態で空気注入排出装置１０３を作動させ、空気セル１０２に対する空気の注入、排出を適宜切換えて空気セル１０２の膨張・収縮を繰返させ、膨張時には身体に対する押圧力を発生させると共に収縮時には押圧状態を解除して、人の肩から背中、さらに腰から脚にかけて揉みとほぼ同等のマッサージ効果を与えることができる。
【０００５】
【発明が解決しようとする課題】
従来のマッサージ器は以上のように構成されていたことから、マットとして用いる関係上、コリの起りやすい首、及び肩から背中にかけての部分に対してマッサージ効果を与えるためのマッサージ器としては、占有面積が大きく、設置する場所が限られると共に、一旦空気を抜いて折畳まないと容易に持運んで場所を変えることができず、不便であるという課題を有した。
【０００６】
また、マットタイプと別のマッサージ器で前記各部分にマッサージ効果を与えられるものも従来から存在するが、これでは人が寝た姿勢の状態で首から背中までの部分にマッサージ効果を与えることはできないという課題を有していた。
本発明は前記課題を解消するためになされたもので、枕部分に頭部を載せてリラックスした姿勢において、首、さらに肩から背中にかけて効果的且つ手軽にマッサージ効果を与えられると共に、構造が簡略な上にコンパクトで製造コスト低減も図れる背中マッサージ部付枕を提供することを目的とする。
【０００７】
【課題を解決するための手段】
本発明に係る背中マッサージ部付枕は、寝た姿勢の人の頭部を支える所定の枕と、当該枕に連結されて背中下側に敷設される背中マットと、可撓性を有する所定形状の中空体で形成され、当該中空体の中空部分に連通する所定の連通路が接続され、前記背中マットの所定箇所に複数配設される流体セルと、前記各流体セルに前記連通路を介して接続され、各流体セルに対し連通路を通じて所定の流体を供給するポンプユニットとを備え、前記連通路が、前記枕内部を通って前記背中マットの枕への連結部位より下の枕下部端部を貫通し、寝た姿勢の人の首の下方に位置する背中マットの枕寄り部分の下側から前記流体セルに各々接続されるものである。
このように本発明においては、枕内部を通る連通路を介して流体を中空部分に出入りさせられる流体セルが背中マットに配設され、ポンプユニットを作動させると背中マットの流体セルに流体が供給されることにより、流体セルで身体に所定のマッサージ効果を与えられると共に、ポンプユニットから流体セルに至る連通路の引回しが容易となり、且つ引回した連通路が外部に現れず、デザイン性が向上する。
【０００８】
また、背中マットにおける流体セルと連通路の接続箇所を枕近傍とし、ちょうど首と背中マットとの間に隙間が生じる位置に合わせることにより、背中マットの他の部分に比べて厚みがより大きくなる連通路接続位置が直接身体に接触しにくく、流体セルの収縮時においても使用者に違和感を与えず、使用感を向上させられる。
【０００９】
また、本発明に係る背中マッサージ部付枕は、寝た姿勢の人の頭部を支える所定の枕と、所定の大きさの可撓性を有する略シート状体で形成され、前記枕と一体に連結されて背中下側に敷設される背中シートと、可撓性を有する所定形状の中空体で形成され、当該中空体の中空部分に連通する所定の連通路が接続され、前記枕の一又は複数の所定箇所及び前記背中シート上の少なくとも背中シート中央に対する横方向両側の二つの所定位置にそれぞれ配設される流体セルと、前記各流体セルに前記連通路を介して接続され、各流体セルに対し連通路を通じて所定の流体を供給するポンプユニットとを備え、前記背中シート上の各流体セルに連通する前記連通路が、前記枕内部を通って背中シートの枕への連結部位より下の枕下部端部を貫通し、寝た姿勢の人の首の下方に位置する背中シートの枕寄り部分の下側から各流体セルに各々接続されるものである。
このように本発明においては、流体を中空部分に出入りさせられる流体セルが枕及び背中シート表面に配設され、枕の上に人が頭部を載せ、且つ背中シート上に身体を載せた状態で、ポンプユニットを作動させて流体セル内に対し流体を供給して流体セルの膨張、収縮を繰返させ、マッサージ対象となる首上部及び肩から背中にかけての部分に接する各流体セルで前記各部分を所定間隔で押圧刺激することにより、リラックスした姿勢の状態で前記各部分に確実に揉みと同等のマッサージ効果を与えられることとなり、流体セルに対する流体の供給量の調整で押圧力の調節が行いやすいことと合わせ、マッサージ器としての使い勝手に優れる。さらに、背中シート上の流体セルと連通路の接続箇所を枕近傍とし、ちょうど首と背中シートとの間に隙間が生じる位置に合わせることにより、背中シートの他の部分に比べて厚みがより大きくなる連通路接続位置が直接身体に接触しにくく、流体セルの収縮時においても使用者に違和感を与えず、使用感を向上させられる。
【００１０】
また、本発明に係る背中マッサージ部付枕は必要に応じて、所定の大きさの可撓性を有するセルシートが前記背中シート上に重ねられ、前記セルシートと背中シートとを略帯状の所定固着部分で一体に固着してセルシートと背中シートとの間に閉じられた空間が少なくとも二つ形成され、当該閉じられた空間を取囲むセルシート及び背中シートの所定部分が前記流体セルをなすものである。このように本発明においては、背中シート上の流体セルを背中シートとセルシートとの固着で形成し、セルシートと背中シートとの間の閉じられた空間を中空部分としてポンプユニットで流体の注入と排出を繰返して膨張、収縮を行わせることにより、流体セルとしてマッサージ対象となる肩から背中にかけての部位を押圧刺激する部分の構造を著しく簡略化できることとなり、製造も容易となり低コスト化が図れる。
【００１１】
また、本発明に係る背中マッサージ部付枕は必要に応じて、前記背中シートとセルシートとの固着部分の一部が、背中シートの縦の中心線を一又は複数回横切る形で連続すると共に、当該連続部分が前記二つの閉じられた空間を隔てる境界となるものである。このように本発明においては、流体セルの中空部分となる背中シートとセルシートとの間の二つの閉じられた空間を互いに隔てる固着部分が背中シートの中心線を一又は複数回横切るように配設され、二つの閉じられた空間がそれぞれ背中シートの縦の中心線を一部跨る状態となることにより、固着部分をより長く設定できることとなり、背中シートとセルシートとの固着強度を高められ、耐久性を向上させられる。
【００１２】
また、本発明に係る背中マッサージ部付枕は必要に応じて、前記流体セルが、前記背中シート上で前記二つの所定位置に加えて、長手方向を背中シート縦方向に向けた細長い中空体として背中シートの中央に配設されるものである。このように本発明においては、背中シート上の中央にも流体セルが配設され、この流体セルに対しても膨張、収縮を行わせ、背中の中央部分を押圧刺激可能とすることにより、流体セルの膨張で背筋を伸そうとする押圧力が加わることとなり、背筋の伸びる状態が繰返されることで脊椎の身体前後方向の歪みを矯正できる。
【００１３】
また、本発明に係る背中マッサージ部付枕は必要に応じて、前記背中シート中央の流体セルとして、背中シート中央部に可撓性の略筒状体を重ね、当該略筒状体の両端部を背中シートにそれぞれ一体に固着し、略筒状体内を閉じた前記中空部分とするものである。このように本発明においては、背中シート中央の流体セルを背中シートに固着した所定の略筒状体で形成し、略筒状体内の閉じられた空間を中空部分としてポンプユニットで流体の注入と排出を繰返して略筒状体部分に膨張、収縮を行わせることにより、マッサージ対象となる背中中央部分を押圧刺激する部分の構造を著しく簡略化できることとなり、製造も容易となり低コスト化が図れる。
【００１４】
また、本発明に係る背中マッサージ部付枕は必要に応じて、前記背中シート上の流体セルが、それぞれ背中シートと独立した二つの中空体で形成され、当該中空体長手方向を背中シート縦方向に向けて中空体一側部と背中シートの横方向端部寄り所定位置とを固着させ、背中シート中央寄りの中空体他側部を所定範囲上下動自在として配設されるものである。このように本発明においては、背中シート上の流体セルをなす中空体が背中シートの側端部寄り位置で一側部を背中シートに固着されて配設され、流体セルがこの固着部分を中心として可動状態となり、膨張時に背中シート中央側から外側に向おうとする動きを発生させることにより、膨張する流体セルが外側に向いながらそれぞれ背中の所定部分を押圧し、特に肩部分の筋肉を伸そうとする外向きの押圧力が加わることとなり、より高いマッサージ効果を与えて肩の筋肉のコリを効率よくほぐすことができ、快適感を高められる。
【００１５】
また、本発明に係る背中マッサージ部付枕は必要に応じて、前記枕の内部に前記流体セルが配設されると共に、当該流体セル配設箇所の下側を少なくとも含む枕底面所定部分に、硬質の略板状体の底板が配設されるものである。このように本発明においては、枕の底面所定部分に底板が配設され、この底板で枕底部の変形を抑えて枕の流体セルの膨張時に押圧力が枕下側に向うのを防ぐことにより、枕を置いた所がマット上などの柔らかい場所である場合でも、流体セルの膨張による押圧力を底板が支えて枕の下側に力を分散させず、押圧力を確実に人体頭部側に向けることができ、優れたマッサージ効果を与えられる。
【００１６】
【発明の実施の形態】
（本発明の第１の実施形態）
以下、本発明の第１の実施形態に係る背中マッサージ部付枕を図１ないし図６に基づいて説明する。図１は本実施の形態に係る背中マッサージ部付枕の斜視図、図２は本実施の形態に係る背中マッサージ部付枕の要部一部切欠側面図、図３は本実施の形態に係る背中マッサージ部付枕の枕内配管状態説明図、図４は本実施の形態に係る背中マッサージ部付枕における肩部空気セル形成状態説明図、図５は本実施の形態に係る背中マッサージ部付枕における背中空気セル形成状態説明図、図６は本実施の形態に係る背中マッサージ部付枕のポンプユニットの概略構成図である。
【００１７】
前記各図に示すように、本実施の形態に係る背中マッサージ部付枕１は、寝た姿勢の人の頭部を支える枕２と、所定の大きさの可撓性を有するシート体で形成され、枕２と一体に連結されて背中下側に敷設される背中シート３と、可撓性を有する所定形状の中空体で形成され、この中空体の中空部分に連通する連通路としての所定の管７が接続され、枕２における人体首上部に当接する所定箇所及び背中シート３上の三つの所定位置にそれぞれ配設される流体セルとしての枕部空気セル４、肩部空気セル５、及び背中空気セル６と、各空気セル４、５、６に前記管７を介して接続され、各空気セル４、５、６に対し管７を通じて流体として空気を繰返し注入もしくは排出するポンプユニット８とを備える構成である。
【００１８】
前記枕２は、頭部を支持可能な十分な大きさとされると共に、上面を人の頭部から首にかけての部分に沿う曲面とされ、人体首上部に当接する内側部分に枕部空気セル４が膨張収縮自在に配設される構成である。この枕２の下部には硬い略板状体の底板２ａが配設され、枕２下部の変形を防いでいる。また、この底板２ａの端部には所定高さ起立した起立部２ｂが一体に形成され、起立部２ｂを貫通して空気の連通路としての管７が背中シート３側の肩部空気セル５及び背中空気セル６に接続される（図２参照）。
【００１９】
この肩部空気セル５及び背中空気セル６に接続される分を含めて、枕２内部には各空気セル４、５、６に接続される管７が内蔵され、枕２の両側に配設される接続コネクタ２ｃとそれぞれ連結されている（図３参照）。両側の接続コネクタ２ｃのうち、一方にはポンプユニット８に繋がっている外部の管７が着脱自在に接続され、各空気セル４、５、６に空気を供給可能とする。外部の管７を接続しない場合、接続コネクタ２ｃ部分には目隠し用の蓋２ｄが付けられる。枕２が所定の厚みを有することから、側面への接続コネクタ２ｃの取付が容易に行える。また、枕２内で各空気セル４、５、６への管７の引回しを行い、且つ枕２の側面に接続コネクタ２ｃを集中配設しているため、外部の管７との接続が容易に行えると共に、外部の管７の接続が分散せずにまとまり、デザイン性も優れたものとなる。
【００２０】
前記背中シート３は、可撓性を有し且つ丈夫な熱可塑性樹脂からなるシート体で形成され、枕２の底板２ａに一端部を螺子止めされて一体に連結される構成である。この背中シート３上に二つの肩部空気セル５及び背中空気セル６が形成され、各空気セル５、６には背中シート３の枕２寄り部分の下側から管７が接続される。この管７接続位置はちょうど首の下方に位置して直接身体と接触しにくく、使用者に違和感を与えない。また、この背中シート３部分には、肩部空気セル５及び背中空気セル６を含む背中シート３全体を包むカバー３ａが配設される。このカバー３ａに覆われた背中シート３で背中マットを形成する。
【００２１】
前記各空気セル４、５、６は、空気注入排出に伴う変形に耐えうる中空体として、枕２の首上部に当接する内側位置に配設されると共に、背中シート３には左右及び中央の三箇所にそれぞれ配設されてなり、接する身体各部分に対し十分にマッサージ効果を与えられる所定の形状及び大きさとされて膨張収縮自在とされる構成である。背中シート３上の肩部空気セル５及び背中空気セル６は、いずれも細長い形状とされてなり、長手方向を背中シート３の縦方向に一致させてそれぞれ配設される。
【００２２】
このうち、背中シート３左右の肩部空気セル５は、背中シート３と同じ熱可塑性樹脂からなる略シート状のセルシート５ａを背中シート３上に重ね、背中シート３の中央から所定寸法離れた二つの所定区画をそれぞれ囲む矩形状の略帯状固着代でセルシート５ａと背中シート３とを熱融着した結果、熱融着部分で閉じられた空間及びこれを挟むセルシート５ａと背中シート３の所定部分をそれぞれ中空部分及び中空体として得られるものである（図４参照）。これら左右の各肩部空気セル５は同じ容積としている。
【００２３】
また、背中シート３中央部の背中空気セル６は、背中シート３と同じ熱可塑性樹脂からなるシート体を略筒状に成形してなる中央筒体６ａを背中シート３の中央で背中シート３及びセルシート５ａ上に重ね、中央筒体６ａ両端部を全て背中シート３に熱融着して、この熱融着部分で内部を閉じた空間とされた中央筒体６ａで形成されるものである（図５参照）。これら肩部空気セル５及び背中空気セル６を各シートの熱融着で背中シート３と一体形成しているため、各空気セル５、６の位置関係がずれないと共に、繰返しの膨張収縮に対する耐久性にも優れる。
【００２４】
前記ポンプユニット８は、空気を吸引・排出する公知の空気ポンプ８ａと、前記空気ポンプ８ａの吸引口、排出口にそれぞれ連通すると共に、前記枕２及び背中シート３の空気セル４、５、６にそれぞれ管７を介して接続され、各管７を通じた各空気セル４、５、６に対する空気の注入状態、排出状態、及び注入排出停止状態をそれぞれ切換える複数の電磁弁８ｂと、この電磁弁８ｂ及びポンプ本体８ａを制御して各空気セル４、５、６に対し空気の注入と排出を繰返してそれぞれ膨張・収縮動作を行わせる制御部８ｃと、この制御部８ｃに対して人が動作指示を与えるための操作部（図示を省略）とを備える構成である。電磁弁８ｂは、空気ポンプ８ａの吸引口、排出口にそれぞれ接続されると共に、枕２の枕部空気セル４、及び背中シート３の肩部空気セル５及び背中空気セル６に対応してそれぞれ個別の管７を介して接続され、空気ポンプ８ａとの連通状態切換は各電磁弁８ｂにより各空気セル４、５、６に関して独立して行われる仕組みとなっている（図６参照）。
【００２５】
次に、前記構成に基づく背中マッサージ部付枕の動作について説明する。まず、マッサージを受けようとする人が枕２に頭部を、背中シート３に背中をそれぞれ載せ、リラックスした姿勢となった状態で、操作部を操作してポンプユニット８の動作開始を指示する。
ポンプユニット８では、空気ポンプ８ａが作動開始して空気を吸引・排出すると共に、制御部８ｃが所定の電磁弁８ｂを制御し、電磁弁８ｂは管７を空気ポンプ８ａの排出側に連通させる状態となる。空気ポンプ８ａは管７を介して各空気セル４、５、６のいずれか一つ又は複数に空気を加圧注入して膨張させ、空気セルの膨張による押圧力が身体接触部分に伝わる。
【００２６】
一方、空気を加圧注入された空気セルが最大限膨張したら、制御部８ｃでの制御により電磁弁８ｂは管７を空気ポンプ８ａの吸引側に連通させる状態に切り替り、空気ポンプ８ａの吸引で空気セルから空気が排出され、空気セルは収縮して押圧力を減衰させ、身体接触部分に押圧力を与えない状態となる。この後、空気セルが最大限収縮したら、電磁弁８ｂが再度管７と空気ポンプ８ａとの連通状態を切り替え、空気セルに空気ポンプ８ａから空気が注入される状態となる。
【００２７】
このようにして、各空気セル４、５、６に対する空気の注入並びに排出の各状態が繰返され、各空気セル４、５、６がそれぞれ膨張・収縮することで、マッサージ対象箇所を枕２及び背中シート３の各空気セル４、５、６位置で断続的に押圧刺激し、揉み動作と同じようなマッサージ効果を与えられる。これら各空気セル４、５、６の膨張による押圧力は、空気ポンプ８ａから各空気セル４、５、６に送込まれる空気量で調節され、制御部８ｃで適切な押圧力となるよう空気量を制御される。
【００２８】
特に、背中シート３では、中央の背中空気セル６が背中の中央部分を断続的に押圧することで、背筋が繰返し伸びる状態となり、脊椎の身体前後方向の歪みを矯正する効果も得られる。また、背中シート３の左右の各肩部空気セル５が背中のうち左右の肩付近をそれぞれ断続的に押圧することで、それぞれ背中肩部分の筋肉にマッサージ効果を与えられ、肩部分のコリを効果的にほぐすことができる。これら背中シート３上の各空気セル５、６については、制御部８ｃによる電磁弁８ｂの制御で、三箇所の各空気セル５、６のうち、中央の背中空気セル６を膨張させている際には左右二つの肩部空気セル５は収縮させ、背中空気セル６によるマッサージ効果を発生させると共に、逆に背中空気セル６を収縮させている際には左右の肩部空気セル５を膨張させ、肩部分にマッサージ効果を与えるようにしている。
【００２９】
このように、本実施の形態に係る背中マッサージ部付枕においては、枕部空気セル４、肩部空気セル５、及び背中空気セル６が枕２及び背中シート３表面に配設され、枕２の上に人が頭部を載せ、且つ背中シート３の上に背中を載せた状態で、ポンプユニット８を作動させて各空気セル４、５、６内に対し空気の注入と排出を繰返して各空気セル４、５、６の膨張、収縮を繰返させ、マッサージ対象となる首、さらに肩から背中にかけての部分をこれらの部分に接触する空気セルで押圧刺激することから、リラックスした姿勢の状態でマッサージ対象の各部分に確実に揉みと同等のマッサージ効果を与えられると共に、ポンプユニット８の各空気セル４、５、６に対する空気の注入・排出が各空気セル４、５、６毎に制御され、枕２と背中シート３の各空気セル５、６でそれぞれ膨張・収縮のタイミングを適切に設定して相互に連係した押圧動作を行えることで、各空気セル５、６による押圧刺激の相乗効果が得られ、身体のコリをほぐす能力が著しく向上する。また、枕２の底面に底板２ａが配設され、底板２ａで枕２底部の変形を抑えて枕部空気セル４膨張時に押圧力が枕２下側に向うのを防げることから、枕２下方へ力を分散させず、確実に押圧力を人体側に向けることができ、首部へ確実にマッサージ効果を与えられる。さらに、各空気セル５、６を背中シート３とセルシート５ａ、並びに、中央筒体６ａの熱融着で形成していることから、構造が簡略で製造しやすく、低コスト化できる。
【００３０】
（本発明の第２の実施形態）
本発明の第２の実施形態に係る背中マッサージ部付枕を図７に基づいて説明する。図７は本実施の形態に係る背中マッサージ部付枕の斜視図である。
前記図７に示すように、本実施の形態に係る背中マッサージ部付枕１は、前記第１の実施形態同様に、枕２と、背中シート３と、枕部空気セル４と、肩部空気セル５と、管７と、ポンプユニット８とを備える一方、異なる点として、背中空気セル６をなす中央筒体６ａが配設されないと共に、背中シート３とセルシート５ａとの熱融着部分の一部が、背中シート３の縦の中心線を複数回横切る略波状に連続して配置されると共に、この連続部分が背中シート３上の左右の肩部空気セル５を隔てる境界となり、左右の肩部空気セル５が背中シート３中央部から左右に広がって配設される構成を有するものである。なお、背中シート３上の左右の肩部空気セル５は同じ容積となっている。
【００３１】
次に、前記構成に基づく背中マッサージ部付枕の動作について説明する。前記第１の実施形態同様、マッサージを受けようとする人が枕２に頭部を、背中シート３に背中をそれぞれ載せ、リラックスした姿勢となった状態で、操作部を操作してポンプユニット８を作動させると、各空気セル４、５に空気を注入して各空気セル４、５を膨張させる状態と、各空気セル４、５から空気を吸引排出して各空気セル４、５を収縮させる状態とが繰返され、マッサージ対象箇所を枕２及び背中シート３の各空気セル４、５位置で断続的に押圧刺激することとなり、揉み動作と同じようなマッサージ効果を与えることが可能となる。
【００３２】
特に、背中シート３では、左右の各肩部空気セル５が背中の中央から左右の肩にかけての部分をそれぞれ断続的に押圧することで、それぞれ背中肩部分の筋肉にマッサージ効果を与えられ、肩部分のコリを効果的にほぐすことができる。これら背中シート３上の肩部空気セル５については、制御部８ｃによる電磁弁８ｂの制御で、肩部空気セル５を左右同時に膨張・収縮させる他、必要に応じて左右交互に膨張・収縮させる状態とすることもできる。
【００３３】
このように、本実施の形態に係る背中マッサージ部付枕においては、肩部空気セル５を形成するために設けられる背中シート３とセルシート５ａとの熱融着部分の一部が背中シート３中央を複数回横切る状態で配置され、熱融着部分の長さをより多く設定していることから、背中シート３とセルシート５ａとの固着強度を高められ、耐久性を向上させられると共に、背中シート３をより簡略な構造として低コスト化、軽量化が図れる。
【００３４】
なお、前記実施の形態に係る背中マッサージ部付枕において、背中シート３中央における背中シート３とセルシート５ａとの熱融着部分は曲線を組合わせた略波状に配置される構成としているが、これに限らず、直線が折れ曲って連続するジグザグ状に配置される構成とすることもできる。
（本発明の第３の実施形態）
本発明の第３の実施形態に係る背中マッサージ部付枕を図８及び図９に基づいて説明する。図８は本実施の形態に係る背中マッサージ部付枕の斜視図、図９は本実施の形態に係る背中マッサージ部付枕の膨張状態説明図である。
【００３５】
前記各図に示すように、本実施の形態に係る背中マッサージ部付枕１は、前記第１の実施形態同様に、枕２と、背中シート３と、枕部空気セル４と、肩部空気セル５と、管７と、ポンプユニット８とを備える一方、異なる点として、背中空気セル６をなす中央筒体６ａが配設されないと共に、背中シート３上の左右の肩部空気セル５が、それぞれ背中シート３から独立した同じ大きさの細長い中空体で形成され、この中空体長手方向を背中シート３縦方向に向けて中空体一側部と背中シート３の横方向端部寄り位置とを熱融着で連結して、背中シート３中央寄りの中空体他側部を所定範囲上下動自在として配設される構成を有するものである。
【００３６】
前記肩部空気セル５は、背中シート３と同じ熱可塑性樹脂からなるシート体を二つ折りして重なる長手方向端部を熱融着して略袋状体を形成し、この略袋状体開口端部（図８中の斜線部分）を背中シート３の横方向端部にそれぞれ融着して固着し、背中シート３から独立した二つの中空体として形成される構成である。次に、前記構成に基づく背中マッサージ部付枕の動作について説明する。まず、マッサージを受けようとする人が枕２に頭部を、背中シート３に背中をそれぞれ載せ、リラックスした姿勢となった状態で、前記第１の実施形態同様に操作部を操作してポンプユニット８を作動させると、各空気セル４、５に空気を注入して各空気セル４、５を膨張させる状態と、各空気セル４、５から空気を吸引排出して各空気セル４、５を収縮させる状態とが繰返され、マッサージ対象箇所を枕２及び背中シート３の各空気セル４、５位置で断続的に押圧刺激することとなり、揉み動作と同等のマッサージ効果を与えることが可能となる。
【００３７】
特に、背中シート３では、左右の肩部空気セル５が膨張すると、肩部空気セル５は背中シート３中央側の端部が熱融着した側の端部を中心に背中シート３から浮上がって中央から外側に向う動きを伴うこととなる（図９（Ｂ）参照）。この肩部空気セル５が左右の肩付近をそれぞれ押圧して肩部分に外向きの力を与えることで、それぞれ肩部分の筋肉に高いマッサージ効果を与えられ、肩部分のコリを確実にほぐすことができる。これら背中シート３上の肩部空気セル５については、前記第２の実施形態同様、制御部８ｃによる電磁弁８ｂの制御で、肩部空気セル５を左右同時に膨張・収縮させる他、必要に応じて左右交互に膨張・収縮させる状態とすることもできる。
【００３８】
このように、本実施の形態に係る背中マッサージ部付枕においては、背中シート３上の肩部空気セル５をなす中空体が背中シート３の側端部寄り位置で一側部を背中シート３に熱融着されて配設され、肩部空気セル５がこの熱融着部分を中心として可動状態となり、膨張時に背中シート３中央側から外側に向う動きを発生することから、膨張する肩部空気セル５が外側に向いながらそれぞれ背中の肩部分を押圧し、肩部分の筋肉を伸そうとする外向きの押圧力を加えて、より高いマッサージ効果を与えられ、肩の筋肉のコリを効率よくほぐすことができ、快適感を高められる。
【００３９】
なお、前記実施の形態に係る背中マッサージ部付枕においては、肩部空気セル５をなす中空体として、まずシート体を二つ折りして重なる長手方向端部を熱融着して略袋状体を形成し、さらに略袋状体を背中シート３に熱融着する構成としているが、これに限らず、初めから袋状である袋状体を背中シート３に熱融着等で固着して肩部空気セル５となす構成とすることもできる。
【００４０】
【発明の効果】
以上のように本発明によれば、枕内部を通る連通路を介して流体を中空部分に出入りさせられる流体セルが背中マットに配設され、ポンプユニットを作動させると背中マットの流体セルに流体が供給されることにより、流体セルで身体に所定のマッサージ効果を与えられると共に、ポンプユニットから流体セルに至る連通路の引回しが容易となり、且つ引回した連通路が外部に現れず、デザイン性が向上するという効果を奏する。
【００４１】

And a back air cell 6 and a pump unit 8 connected to each air cell 4, 5, 6 via the pipe 7, and repeatedly injecting or discharging air as a fluid through the pipe 7 to each air cell 4, 5, 6. It is the structure provided with.
[0018]
The pillow 2 is large enough to support the head, and the upper surface is a curved surface along a portion from the head of the person to the neck. Is configured to expand and contract freely. A bottom plate 2a, which is a hard substantially plate-like body, is disposed at the lower part of the pillow 2 to prevent the lower part of the pillow 2 from being deformed. Further, an upright portion 2b standing up to a predetermined height is integrally formed at the end of the bottom plate 2a, and a tube 7 serving as an air communication path penetrating the upright portion 2b is a shoulder air cell 5 on the back seat 3 side. And connected to the back air cell 6 (see FIG. 2).
[0019]
Including the portion connected to the shoulder air cell 5 and the back air cell 6, pipes 7 connected to the air cells 4, 5, 6 are built in the pillow 2 and arranged on both sides of the pillow 2. The connection connectors 2c are connected to each other (see FIG. 3).

Since the pillow 2 has a predetermined thickness, the connection connector 2c can be easily attached to the side surface. Further, the pipe 7 is routed to the air cells 4, 5, 6 in the pillow 2, and the connection connector 2 c is concentrated on the side surface of the pillow 2, so that the connection with the external pipe 7 is possible. It can be easily performed, the connections of the external pipes 7 are gathered without being dispersed, and the design is excellent.
[0020]
The back sheet 3 is formed of a sheet body made of a flexible and durable thermoplastic resin, and has a configuration in which one end is screwed to the bottom plate 2a of the pillow 2 and is integrally connected. Two shoulder air cells 5 and a back air cell 6 are formed on the back sheet 3, and a tube 7 is connected to each air cell 5, 6 from the lower side of the back sheet 3 near the pillow 2. This connection position of the tube 7 is located just below the neck so that it does not come into direct contact with the body and does not give the user a sense of incongruity. Further, a cover 3 a that wraps the entire back sheet 3 including the shoulder air cell 5 and the back air cell 6 is disposed on the back sheet 3 portion. A back mat is formed by the back sheet 3 covered with the cover 3a.
[0021]
The air cells 4, 5, and 6 are disposed at inner positions that contact the top of the neck of the pillow 2 as hollow bodies that can withstand deformation due to air injection and discharge, and the back seat 3 has left and right and center It is arranged at three locations, and has a predetermined shape and size that can give a sufficient massage effect to each part of the body that comes into contact with each other, so that it can expand and contract freely. Both the shoulder air cell 5 and the back air cell 6 on the back sheet 3 are formed in an elongated shape, and are arranged such that the longitudinal direction thereof coincides with the longitudinal direction of the back sheet 3.
[0022]
Among these, the shoulder air cells 5 on the left and right of the back sheet 3 are overlapped on the back sheet 3 by a substantially sheet-like cell sheet 5a made of the same thermoplastic resin as the back sheet 3 and separated from the center of the back sheet 3 by a predetermined dimension. As a result of heat-sealing the cell sheet 5a and the back sheet 3 with a rectangular substantially belt-like fixing margin surrounding each of the two predetermined sections, a space closed by the heat-sealed portion and the cell sheet 5a and the back sheet 3 sandwiching the space are sandwiched. These predetermined portions are obtained as a hollow portion and a hollow body, respectively (see FIG. 4). These left and right shoulder air cells 5 have the same volume.
[0023]
The back air cell 6 at the center of the back sheet 3 has a central cylinder 6a formed by molding a sheet body made of the same thermoplastic resin as the back sheet 3 into a substantially cylindrical shape at the center of the back sheet 3 and the back sheet 3 and It is formed by a central cylindrical body 6a which is overlapped on the cell sheet 5a, and both ends of the central cylindrical body 6a are heat-sealed to the back sheet 3 and the interior is closed by this heat-sealed portion. (See FIG. 5). Since the shoulder air cell 5 and the back air cell 6 are integrally formed with the back sheet 3 by thermal fusion of the respective sheets, the positional relationship between the air cells 5 and 6 is not shifted and durability against repeated expansion and contraction is achieved. Excellent in properties.
[0024]
The pump unit 8 communicates with a known air pump 8a that sucks and discharges air, and a suction port and a discharge port of the air pump 8a, and air cells 4, 5, 6 of the pillow 2 and the back sheet 3 respectively. A plurality of solenoid valves 8b that are respectively connected to the air cells 4, 5, and 6 through the pipes 7 and switch between the air injection state, the discharge state, and the injection / discharge stop state, respectively. 8b and the pump body 8a to control each of the air cells 4, 5 and 6 to repeatedly inject and discharge air to perform expansion / contraction operations, and a person operates to this control unit 8c. It is a structure provided with the operation part (illustration omitted) for giving an instruction | indication. The electromagnetic valve 8b is connected to the suction port and the discharge port of the air pump 8a, and corresponds to the pillow part air cell 4 of the pillow 2 and the shoulder part air cell 5 and back air cell 6 of the back seat 3, respectively. It connects via the separate pipe | tube 7, The communication state switching with the air pump 8a becomes a mechanism performed independently regarding each air cell 4, 5, 6 by each electromagnetic valve 8b (refer FIG. 6).
[0025]
Next, operation | movement of the pillow with a back massage part based on the said structure is demonstrated. First, a person who wants to receive a massage places his head on the pillow 2 and his back on the back sheet 3, and instructs the pump unit 8 to start operating by operating the operation unit in a relaxed posture. .
In the pump unit 8, the air pump 8a starts operating and sucks and discharges air, and the control unit 8c controls a predetermined electromagnetic valve 8b, and the electromagnetic valve 8b causes the pipe 7 to communicate with the discharge side of the air pump 8a. It becomes a state. The air pump 8a pressurizes and injects air into any one or a plurality of the air cells 4, 5 and 6 via the pipe 7, and the pressing force due to the expansion of the air cell is transmitted to the body contact portion.
[0026]
On the other hand, when the air cell pressurized with air is expanded to the maximum extent, the solenoid valve 8b is switched to a state where the pipe 7 communicates with the suction side of the air pump 8a by the control of the control unit 8c, and the suction of the air pump 8a is performed. As a result, air is discharged from the air cell, and the air cell contracts to attenuate the pressing force, and does not apply the pressing force to the body contact portion. Thereafter, when the air cell contracts to the maximum extent, the electromagnetic valve 8b switches the communication state between the pipe 7 and the air pump 8a again, and the air cell is in a state where air is injected from the air pump 8a.
[0027]
In this way, each state of air injection and discharge to each air cell 4, 5, 6 is repeated, and each air cell 4, 5, 6 expands and contracts, so that the massage object location is changed to the pillow 2 and The air cells 4, 5, 6 on the back sheet 3 are intermittently pressed and stimulated to give a massage effect similar to that of the massage operation. The pressing force due to the expansion of each of the air cells 4, 5, 6 is adjusted by the amount of air sent from the air pump 8a to each of the air cells 4, 5, 6, so that the control unit 8c has an appropriate pressing force. The amount is controlled.
[0028]
In particular, in the back sheet 3, the central back air cell 6 intermittently presses the central portion of the back, whereby the back muscles are repeatedly stretched, and the effect of correcting the distortion of the spine in the front-rear direction is also obtained. In addition, the left and right shoulder air cells 5 of the back sheet 3 intermittently press the vicinity of the left and right shoulders of the back, respectively. Can be effectively loosened. Regarding the air cells 5 and 6 on the back seat 3, the central back air cell 6 is inflated among the three air cells 5 and 6 by the control of the electromagnetic valve 8b by the control unit 8c. The two left and right shoulder air cells 5 are contracted to generate a massage effect by the back air cell 6 and conversely when the back air cell 6 is contracted, the left and right shoulder air cells 5 are expanded. The massage is given to the shoulder part.
[0029]
Thus, in the pillow with a back massage part according to the present embodiment, the pillow part air cell 4, the shoulder part air cell 5, and the back air cell 6 are disposed on the surfaces of the pillow 2 and the back sheet 3, and the pillow 2 With the person on the head and the back on the back sheet 3, the pump unit 8 is operated to repeatedly inject and exhaust air into the air cells 4, 5, and 6. The air cells 4, 5 and 6 are repeatedly expanded and contracted, and the neck from which the massage is performed and the part from the shoulder to the back are pressed and stimulated by the air cell in contact with these parts. With this, it is possible to reliably give each part to be massaged a massage effect equivalent to itchiness, and control the air injection / discharge of each air cell 4, 5, 6 of the pump unit 8 for each air cell 4, 5, 6 Pillow 2 and back The air cells 5 and 6 of the air cell 3 can set the timing of expansion / contraction appropriately and perform the pressing operation linked to each other, so that the synergistic effect of the pressure stimulation by the air cells 5 and 6 can be obtained. The ability to loosen the stiffness is significantly improved. In addition, a bottom plate 2a is disposed on the bottom surface of the pillow 2, and the bottom plate 2a suppresses deformation of the bottom of the pillow 2 to prevent the pressing force from being directed to the lower side of the pillow 2 when the pillow portion air cell 4 expands. The force can be surely directed to the human body without distributing the force to the neck, and a massage effect can be reliably given to the neck. Furthermore, since the air cells 5 and 6 are formed by thermal fusion of the back sheet 3, the cell sheet 5a, and the central cylinder 6a, the structure is simple and easy to manufacture, and the cost can be reduced.
[0030]
(Second embodiment of the present invention)
A pillow with a back massage portion according to a second embodiment of the present invention will be described with reference to FIG. FIG. 7 is a perspective view of the pillow with back massage part according to the present embodiment.
As shown in FIG. 7, the pillow with back massage part 1 according to the present embodiment is similar to the first embodiment in that the pillow 2, the back sheet 3, the pillow part air cell 4, and the shoulder air. While the cell 5, the pipe 7, and the pump unit 8 are provided, the difference is that the central cylinder 6 a that forms the back air cell 6 is not provided, and the heat-sealed portion between the back sheet 3 and the cell sheet 5 a is not provided. A portion is continuously arranged in a substantially wave shape that crosses the vertical center line of the back seat 3 a plurality of times, and this continuous portion serves as a boundary that separates the left and right shoulder air cells 5 on the back seat 3. The shoulder air cell 5 has a configuration in which the shoulder air cell 5 extends from the center of the back seat 3 to the left and right. The left and right shoulder air cells 5 on the back seat 3 have the same volume.
[0031]
Next, operation | movement of the pillow with a back massage part based on the said structure is demonstrated. As in the first embodiment, a person who wants to receive a massage puts his head on the pillow 2 and his back on the back sheet 3, and operates the operation unit in a relaxed posture to operate the pump unit 8. Is activated, air is injected into the air cells 4 and 5 to expand the air cells 4 and 5, and air is sucked and discharged from the air cells 4 and 5 to contract the air cells 4 and 5. The state to be repeated is repeated, and the massage target portion is intermittently pressed and stimulated at the positions of the air cells 4 and 5 of the pillow 2 and the back sheet 3, so that it is possible to provide a massage effect similar to the massage operation. .
[0032]
In particular, in the back seat 3, the left and right shoulder air cells 5 intermittently press the portions from the center of the back to the left and right shoulders, respectively, thereby giving a massage effect to the muscles of the back and shoulder portions, respectively.
