Description

【0001】
【発明の属する技術分野】
本発明は、マッサージ器において膨張してマッサージ効果を発揮する各空気セルに対する空気の供給と排出を制御し、空気セルによる押圧力を適宜調整するマッサージ器動作制御方法に関する。
【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流体による中空体の膨張・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、適切な箇所に配設された中空の空気セルを空気で膨張させて身体にマッサージ効果を与える空気圧式のものは、身体の多くの箇所に容易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。そして、この空気圧式のマッサージ器では、空気セルを内蔵して直接身体に接するマッサージ器本体と共に、このマッサージ器本体とは別に設けられて空気セルに対し空気の供給、排出を行う空気供給排出装置が合わせて利用され、空気の供給及び排出状態をそれぞれ制御されつつ、空気の供給、排出を繰返して断続的に身体に押圧力を与える仕組みとなっていた。このような空気圧式のマッサージ器の一例を図7及び図8に示す。図7は従来のマッサージ器の斜視図、図8は従来のマッサージ器における空気供給・排出動作状態説明図である。
【0004】
前記各図に示す従来のマッサージ器100は、人の身体に接してマッサージ効果を与える所定形状のマッサージ器本体101と、このマッサージ器本体101内所定位置に収納されて空気の供給、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に対し空気の供給、排出を行う空気供給排出装置103とを備える構成である。
【0005】
前記空気供給排出装置103は、空気セル102を膨張させる空気を所定圧力で送出す公知のポンプ104と、前記ポンプ104と空気セル102とを連通させる状態と、空気セル102と外部とを連通させる状態とを切替え自在とする複数の切替弁105と、各切替弁105を制御して各空気セル102に対し空気の供給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106とを備える構成である(図2参照)。
【0006】
この従来のマッサージ器100では、人がマッサージ器本体101に身体を当接させた状態で空気供給排出装置103の動作を開始させると、制御部106が空気セル102に対する空気の供給、排出を切替弁105で適宜切替えて空気セル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、マッサージ器本体101の空気セル102位置で所定のマッサージ効果を与えることができた。
【0007】
このマッサージ器100における空気セル102から身体への押圧力の調整は、空気供給排出装置103の制御部106が切替弁105の切替タイミングを変え、空気セル102に対する空気供給開始から空気排出開始までの期間を適宜調整し、空気セル102内への供給空気量を変えて空気セル102の膨張状態を変化させることで行われていた。基準となるのは空気セル102を最大限膨張させた状態で、空気セル102をこの最大膨張状態まで膨張させると、空気セル102で発生可能な最大の押圧力を空気セル102から身体に与えられる状態となる(図8(A)参照)。この最大膨張状態での押圧力が強すぎる場合には、使用者の操作に基づいて制御部106が切替弁105の切替時期を早め、空気セル102が最大膨張状態になる前に空気排出状態とし、空気セル102に供給される空気量を抑えて押圧力を弱める仕組みとなっている(図8(B)参照)。
【0008】
【発明が解決しようとする課題】
従来のマッサージ器の押圧力調整は以上のように行われていたことから、切替弁105の切替時期を早めて空気セル102内への空気供給量を抑えると、押圧力は弱まるものの、空気セル102が膨張している状態からすぐ空気排出による収縮状態に移行することとなり、結果として身体に押圧力の伝わる時間が短くなり過ぎ、身体にマッサージ効果を適切に与えられなくなってしまうという課題を有していた。
【0009】
本発明は前記課題を解消するためになされたもので、空気セルを最大膨張状態より小さく膨張させた状態でも、膨張状態を所定期間維持させて身体に押圧力が適切に加わるようにし、確実にマッサージ効果を与えられるマッサージ器動作制御方法を提供することを目的とする。
【0011】
【課題を解決するための手段】
本発明に係るマッサージ器動作制御方法は、膨張収縮自在の所定形状を有する中空体で形成される空気セルと、当該空気セルに対し空気を供給するポンプと、前記空気セルとポンプとの間に一つ配設され、空気セルと連通する対象をポンプ又はポンプ以外の所定箇所のいずれかに切替える切替弁と、前記ポンプ及び切替弁を制御する制御手段とを備えるマッサージ器において、切替弁での空気セルをポンプに連通させる空気供給状態と空気セルをポンプ以外の所定箇所に連通させる空気排出状態とを所定周期で切替え、且つ、前記空気供給状態開始時から前記空気排出状態開始時までの間に、空気セル内の空気量を略一定に維持する期間を少なくとも一度は設定する動作制御方法であって、前記切替弁の空気供給状態と空気排出状態との切替時期及び/又は前記ポンプのON状態とOFF状態との切替時期を制御して前記空気セルへの空気供給量を異ならせ、押圧力を最大とする第1の空気供給量モードと押圧力を弱くする第2の空気供給量モードとを与えると共に、前記第1の空気供給量モード及び前記第2の空気供給量モードについて、前記空気供給状態開始時から前記空気排出状態開始時までの期間の長さを略一致させ、前記第1の空気供給量モードの場合に、前記空気セルが最大膨張状態に達しても前記ポンプを停止させずに動作継続させ、前記第2の空気供給量モードの場合に、前記空気セル内の空気量を略一定に維持する期間を当該空気量略一定状態での空気セル内の空気量が少ないほどより長く設定するものである。このように本発明においては、空気セルへの空気供給量を異ならせた第1及び第2の空気供給量モードを設定する一方、空気セルが所定の膨張状態となる空気供給開始時から空気排出開始時までの期間の長さを、空気供給量モードによらず略一致させ、押圧力を弱くする第2の空気供給量モードの場合は、膨張した空気セルの大きさが小さい場合ほど空気セルの空気量を略一定に維持する状態をより長く継続させることにより、空気セルの膨張状態が押圧力としてマッサージ対象となる身体に伝わる時間が十分に確保され、所定の押圧力で身体にマッサージ効果を確実に与えることができる。また、押圧力を最大とする第1の空気供給量モードの場合は、空気セルが最大膨張状態に達してもポンプを停止させずに動作継続させることにより、一般的に利用する最大押圧力でのマッサージ動作でポンプの制御が容易になり、ポンプへの負担を減らせると共に、空気セルへの空気供給開始時における空気セルの膨張の立上がりが速く、身体へのマッサージ効果を一層高められる。
【0013】
【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の実施形態に係るマッサージ器動作制御方法を図1ないし図3に基づいて説明する。図1は本実施の形態に係るマッサージ器動作制御方法を適用するマッサージ器の斜視図、図2は本実施の形態に係るマッサージ器動作制御方法を適用するマッサージ器における空気供給排出装置の概略構成図、図3は本実施の形態に係るマッサージ器動作制御方法による空気供給・排出動作状態説明図である。
【0014】
前記各図に示すように、本実施の形態に係る動作制御方法を適用するマッサージ器1は、前記従来同様、マッサージ器本体101と、空気セル102と、空気供給排出装置103とを備える構成である。
前記空気セル102は、膨張収縮自在の所定形状を有する中空体で形成され、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107が接続され、マッサージ器本体101の所定箇所にそれぞれ配設される構成である。
【0015】
前記空気供給排出装置103は、前記従来の空気供給排出装置103同様に、ポンプ104と、切替弁105と、制御部106とを備える構成を有するものであり、各空気セル102に前記管107を介して接続され、各空気セル102に対し管107を通じて空気を繰返し供給もしくは排出する。前記切替弁105は、空気セル102をポンプ104に連通させる状態と、空気セル102を外部に連通させる状態とを切替えるものである。
【0016】
前記制御部106は、ポンプ104及び各切替弁105をそれぞれ制御して各空気セル102に対し空気の供給と排出を繰返してそれぞれ膨張・収縮動作を行わせるものである。この制御部106は使用者によって操作される操作部(図示を省略)を別体として配設されており、所定の操作で動作開始・終了、押圧力の強さ等を指示される。
【0017】
次に、本実施の形態に係るマッサージ器動作制御方法によるマッサージ器の動作について説明する。まず、使用者がマッサージ器本体101に身体の所定部分を当接させた状態で、操作部(図示を省略)を操作して動作開始を指示すると、制御部106はポンプ104を作動開始させ、空気を送出させると共に、所定の切替弁105を制御し、ポンプ104と空気セル102とを連通させる状態とする。この状態では、ポンプ104からの空気が切替弁105及び管107を介して空気セル102に加圧注入されて空気セル102を膨張させ、この空気セル102の膨張による押圧力がマッサージ器本体101を介して身体接触部分に伝わることとなる(図3参照;期間t1)。
【0018】
空気セル102の膨張を開始させてから所定時間経過すると、制御部106はポンプ104を停止させ、ポンプ104から空気セル102への空気供給を止める。この状態では、空気セル102内の空気の一部が管107及び切替弁105を介してポンプ104側へ戻るものの、ほとんどの空気が空気セル102内に残り、空気セル102は膨張した状態のまま維持され、身体接触部分に所定の押圧力を与え続ける状態となる(図3参照;期間t2)。
【0019】
さらに、空気供給が停止して所定時間経過すると、制御部106は新たに切替弁105を制御して、空気セル102を外部に連通させる状態に切替える(図2参照)。この状態では、空気セル102から空気が管107及び切替弁105を介して排出され、空気セル102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(図3参照;期間t3)。この後、空気セル102が収縮して所定時間経過すると、制御部106はポンプ104を動作状態とすると共に、切替弁105における連通状態を切り替え、空気セル102にポンプ104から空気が供給される状態とする。
【0020】
こうして、前記の空気セル102に対する空気の供給、供給停止、並びに排出の各状態が順に繰返され、そのたびに、空気セル102が膨張し、所定期間大きさを維持した後収縮することで、マッサージ対象箇所をマッサージ器本体101の空気セル102位置で断続的に押圧刺激し、マッサージ効果を与えられる。
これら空気セル102の膨張による押圧力は、ポンプ104から空気セル102への空気供給量を決める空気供給開始からポンプ停止までの期間、すなわち、空気供給期間の長さで調節され、使用者の操作に基づいて制御部106で切替弁105の連通状態とポンプ動作をそれぞれ制御して空気供給量のそれぞれ異なる複数の空気供給量モードを設定し、空気セル102内の空気量を調節して適切な押圧力となるようにしている。
【0021】
第一の空気供給量モードとして、押圧力を最大にする場合(図3(A)参照)は、空気供給期間を長くして空気セル102を最大膨張状態まで膨張させる(図3(A)参照;期間t1)。この最大膨張状態に達したら、制御部106がポンプ104を停止させて空気セル102への空気供給を停止する。この空気供給停止後、切替弁105切替による空気排出開始までの間、最大膨張状態の空気セル102から身体に押圧力が加わる仕組みとなっている(図3(A)参照;期間t2)。この空気供給停止から空気排出開始までの期間の長さとしては、例えば1秒ないし10秒程度が与えられる。
【0022】
一方、第二の空気供給量モードとして、押圧力を弱くする場合(図3(B)参照)は、使用者の押圧力調整操作に基づいて、制御部106がポンプ104の停止するタイミングを早めて空気セル102が最大膨張状態になる以前にポンプ104を停止させ、空気セル102への空気供給量を最大膨張状態より減らす(図3(B)参照;期間t1)。ポンプ104による空気供給が停止して空気排出が開始されるまでの間(図3(B)参照;期間t2)、所定の空気量に維持された空気セル102から最大膨張状態に比べて弱められた押圧力が身体に加わることとなる。ただし、この空気供給停止から空気排出開始までの期間(図3(B)参照;期間t2)は空気セル102を最大膨張状態まで膨張させる最大押圧力の場合(図3(A)参照)と同じであり、空気供給停止後に空気セル102から身体に押圧力の加わる期間をどの空気量モードでも一定として、身体へのマッサージ効果を確保している。
【0023】
このように、本実施の形態に係るマッサージ器動作制御方法においては、空気セル102への空気供給量をポンプ104の停止タイミングを変えて複数通り設定する一方、空気セル102に対する空気供給停止から空気排出開始までの期間を決定するポンプ104停止から切替弁105を切り替えるまでの時間を空気供給量の違いによらず同じとして、膨張した空気セル102の大きさが小さい場合、すなわち押圧力が弱い場合でも、ポンプ104を停止させて空気セル102の空気量を維持する状態を所定期間継続させることから、空気供給量が変化しても空気セル102の膨張状態が押圧力としてマッサージ対象となる身体に伝わる時間が一様に確保され、空気セル102への空気供給量に応じた押圧力で身体にマッサージ効果を適切に与えることができる。
【0024】
(本発明の第2の実施形態)
本発明の第2の実施形態に係るマッサージ器動作制御方法を図4に基づいて説明する。図4は本実施の形態に係るマッサージ器動作制御方法による空気供給・排出動作状態説明図である。
本実施の形態に係るマッサージ器動作制御方法は、前記第1の実施形態同様に、空気供給排出装置103の制御部106でポンプ104及び切替弁105の動作状態を適宜切替えて空気セル102に対する空気の供給、供給停止、並びに排出の各状態を順に繰返させる一方、異なる点として、空気セル102に対する空気供給開始から空気排出開始までの期間を空気セル102への空気供給量によらず一定とするものである。
【0025】
この本実施の形態に係るマッサージ器動作制御方法によるマッサージ器の動作について説明する。まず、使用者がマッサージ器本体101に身体の所定部分を当接させた状態で、操作部(図示を省略)を操作して動作開始を指示すると、制御部106はポンプ104を作動開始させ、空気を送出させると共に、所定の切替弁105を制御し、ポンプ104と空気セル102とを連通させる状態とする。この状態では、ポンプ104からの空気が切替弁105及び管107を介して空気セル102に加圧注入されて空気セル102を膨張させ、この空気セル102の膨張による押圧力がマッサージ器本体101を介して身体接触部分に伝わることとなる(図4参照;期間t1)。
【0026】
空気セル102の膨張を開始させてから所定時間経過すると、制御部106はポンプ104を停止させ、ポンプ104から空気セル102への空気供給を止める。この状態では、空気セル102内の空気の一部が管107及び切替弁105を介してポンプ104側へ戻るものの、ほとんどの空気が空気セル102内に残り、空気セル102は膨張した状態のまま維持され、身体接触部分に所定の押圧力を与え続ける状態となる(図4参照;期間t2)。
【0027】
さらに、空気供給が停止して所定時間経過すると、制御部106は新たに切替弁105を制御して、空気セル102を外部に連通させる状態に切替える(図2参照)。この状態では、空気セル102から空気が管107及び切替弁105を介して排出され、空気セル102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(図4参照;期間t3)。この後、空気セル102が収縮して所定時間経過すると、制御部106はポンプ104を動作状態とすると共に、切替弁105における連通状態を切り替え、空気セル102にポンプ104から空気が供給される状態とする。
【0028】
こうして、前記の空気セル102に対する空気の供給、供給停止、並びに排出の各状態が順に繰返され、そのたびに、空気セル102が膨張し、所定期間大きさを維持した後収縮することで、マッサージ対象箇所をマッサージ器本体101の空気セル102位置で断続的に押圧刺激し、マッサージ効果を与えられる。
これら空気セル102の膨張による押圧力は、ポンプ104から空気セル102への空気供給量を決める空気供給開始からポンプ停止までの期間、すなわち、空気供給期間の長さで調節され、使用者の操作に基づいて制御部106で切替弁105の連通状態とポンプ動作をそれぞれ制御して空気供給量のそれぞれ異なる複数の空気供給量モードを設定し、空気セル102内の空気量を調節して適切な押圧力となるようにしている。
【0029】
第一の空気供給量モードとして、押圧力を最大にする場合(図4(A)参照)は、空気供給期間を長くして空気セル102を最大膨張状態まで膨張させる(図4(A)参照;期間t1)。この最大膨張状態に達したら、制御部106がポンプ104を停止させて空気セル102への空気供給を停止する。この空気供給停止後、切替弁105切替による空気排出開始までの間、最大膨張状態の空気セル102から身体に押圧力が加わる仕組みとなっている(図4(A)参照;期間t2)。
【0030】
一方、第二の空気供給量モードとして、押圧力を弱くする場合(図4(B)参照)は、使用者の押圧力調整操作に基づいて、制御部106がポンプ104の停止するタイミングを早めて空気セル102が最大膨張状態になる以前にポンプ104を停止させ、空気セル102への空気供給量を最大膨張状態より減らす(図4(B)参照;期間t1)。ポンプ104による空気供給が停止して空気排出が開始されるまでの間(図4(B)参照;期間t2)、所定の空気量に維持された空気セル102から最大膨張状態に比べて弱められた押圧力が身体に加わることとなる。ただし、空気セル102に対する空気供給開始から空気排出開始までの期間(図4(B)参照;t1+t2)は空気セル102を最大膨張状態まで膨張させる最大押圧力の場合(図4(A)参照)と同じであり、空気供給停止後も空気セル102から身体に押圧力の加わる期間が十分確保され、身体に押圧力に応じたマッサージ効果を与えられる。
【0031】
このように、本実施の形態に係るマッサージ器動作制御方法においては、空気セル102への空気供給量をポンプ104の停止タイミングを変えて複数通り設定する一方、空気セル102に対する空気供給開始から空気排出開始までの期間を決定する切替弁105の切替動作タイミングを空気供給量の違いによらず同じとして、膨張した空気セル102の大きさが小さい場合、すなわち押圧力が弱い場合ほど、ポンプ104を停止させて空気セル102の空気量を維持する状態をより長く継続させることから、空気供給量が減少しても空気セル102の膨張状態が押圧力としてマッサージ対象となる身体に伝わる時間が十分に確保され、空気セル102への空気供給量に応じた押圧力で身体にマッサージ効果を確実に与えることができる。
【0032】
(本発明の第3の実施形態)
本発明の第3の実施形態に係るマッサージ器動作制御方法を図5に基づいて説明する。図5は本実施の形態に係るマッサージ器動作制御方法による空気供給・排出動作状態説明図である。
本実施の形態に係るマッサージ器動作制御方法は、前記第2の実施形態同様に、空気供給排出装置103の制御部106でポンプ104及び切替弁105の動作状態を適宜切替えて空気セル102に対する空気の供給、供給停止、並びに排出の各状態を順に繰返させる一方、異なる点として、空気セル102を最大膨張状態まで膨張させて押圧力を最大とする場合には、空気セル102が最大膨張状態に達してもポンプ104を停止させずにそのまま動作継続させるものである。
【0033】
この本実施の形態に係るマッサージ器動作制御方法によるマッサージ器の動作について説明する。まず、前記第1の実施形態同様、使用者がマッサージ器本体101に身体の所定部分を当接させた状態で、操作部(図示を省略)を操作して動作開始を指示すると、制御部106はポンプ104を動作させて空気送出を開始させると共に、切替弁105を動作させてポンプ104と空気セル102との連通状態に切替える。これにより、ポンプ104から空気が空気セル102に注入されて空気セル102を膨張させ、この空気セル102の膨張による押圧力が身体に伝わる(図5参照;期間t1)。
【0034】
ここで、使用者の押圧力調整操作で最大押圧力を得られる状態(第一の空気供給量モード)となっている場合(図5(A)参照)には、空気セル102の膨張を開始させてから所定時間経過すると、空気セル102が最大膨張状態に達し、ポンプ104からの空気供給が続けられても空気セル102内にはそれ以上空気が入らなくなる。この最大膨張状態に到達してから切替弁105切替による空気排出開始までの間、空気セル102において大きさの変化しない一定状態が継続し、この間、空気セル102は身体に押圧力を与え続ける(図5(A)参照;期間t2)。
【0035】
空気セル102の最大膨張状態到達後、さらに所定時間経過すると、制御部106は切替弁105を制御して、空気セル102を外部に連通させる状態に切替える。この状態では、空気セル102から空気が管107及び切替弁105を介して排出され、空気セル102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(図5(A)参照;期間t3)。この後、空気セル102が収縮して所定時間経過すると、制御部106は切替弁105における連通状態を切り替え、空気セル102にポンプ104から空気が供給される状態とする。
【0036】
こうして、前記の空気セル102に対する空気の供給、排出の各状態が順に繰返され、そのたびに、空気セル102が膨張し、所定期間大きさを維持した後収縮することで、身体のマッサージ対象箇所を最大の押圧力で断続的に押圧刺激し、マッサージ効果を与えられる。なお、ポンプ104は、動作開始後、押圧力が調整されない限り、空気セル102の状態によらずそのまま空気送出動作をマッサージ器1全体としての動作停止まで継続する。
【0037】
一方、使用者の押圧力調整操作で押圧力を最大押圧力より弱めた状態(第二の空気供給量モード)となっている場合(図5(B)参照)には、空気セル102の膨張を開始させてから所定時間経過後、制御部106が空気セル102を最大膨張状態とする以前にポンプ104を停止させる。前記第1の実施形態同様、ポンプ104停止後は空気セル102内の空気の一部がポンプ104側へ戻るものの、ほとんどの空気が空気セル102内に残る。空気セル102は最大膨張状態より少ない所定の空気量に維持され、この空気セル102から最大膨張状態に比べて弱められた押圧力が身体に加わる状態となる(図5(B)参照;期間t2)。
【0038】
さらに、空気供給を停止させて所定時間経過後、制御部106は切替弁105を制御して、空気セル102を外部に連通させる状態に切替える。この状態では、空気セル102から空気が管107及び切替弁105を介して排出され、空気セル102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(図5(B)参照;期間t3)。この空気排出状態に切り替るまでの空気供給開始時点からの時間(図5(B)参照;t1+t2)は、空気セル102を最大膨張状態まで膨張させる最大押圧力の場合(図5(A)参照)と同じであり、空気供給停止後に空気セル102の空気量を維持して身体に押圧力を加えられる期間は十分確保され、身体に押圧力に応じた適切なマッサージ効果を与えられる。
【0039】
この後、空気セル102が収縮して所定時間経過すると、制御部106はポンプ104を動作状態とすると共に、切替弁105における連通状態を切り替え、空気セル102にポンプ104から空気が供給される状態とする。
こうして、前記の空気セル102に対する空気の供給、供給停止、並びに排出の各状態が順に繰返され、そのたびに、空気セル102が膨張し、所定期間大きさを維持した後収縮することで、マッサージ対象箇所を所定の押圧力で断続的に押圧刺激し、マッサージ効果を与えられる。
【0040】
このように、本実施の形態に係るマッサージ器動作制御方法においては、空気セル102を最大膨張状態まで膨張させて最大押圧力を得る場合に、ポンプ104を停止させずにそのまま動作させ、空気セル102内の空気量が略一定に維持される状態として空気セル102への空気注入が限界に達した状態を用いることから、一般的に利用する最大押圧力でのマッサージ動作でポンプ104の制御が容易になり、ポンプ104への負担を減らせると共に、空気セル102への空気供給開始時における空気セル102の膨張の立上がりが速く、身体へのマッサージ効果を一層高められる。
【0041】
なお、前記第2及び第3の各実施形態に係るマッサージ器動作制御方法においては、空気セル102に対する各空気供給量モードで、空気供給状態開始及び空気排出状態開始の各タイミングを一致させ、空気供給状態開始時から空気排出状態開始時までの期間の長さを等しくする構成としているが、これに限らず、空気セル102への空気供給量を複数通り設定する場合に、切替弁105の空気供給状態と空気排出状態との切替時期及び/又はポンプ104のON状態とOFF状態との切替時期をそれぞれ複数通り設定し、空気供給状態開始及び空気排出状態開始の各タイミング、並びに空気供給状態開始時から空気排出状態開始時までの期間の長さを異ならせる構成とすることもでき、例えば、図6に示すように、空気セル102における空気量一定状態での切替弁105切替による空気排出開始のタイミングを空気供給量モード毎に適宜変化させ、空気セル102から身体に伝わる押圧力の作用期間を調整することもでき、空気セル102からの押圧タイミングを押圧力の強弱に適切に対応させてマッサージ効果の最適化が図れる。

以上のように本発明によれば、空気セルへの空気供給量を異ならせた第1及び第2の空気供給量モードを設定する一方、空気セルが所定の膨張状態となる空気供給開始時から空気排出開始時までの期間の長さを、空気供給量モードによらず略一致させ、押圧力を弱くする第2の空気供給量モードの場合は、膨張した空気セルの大きさが小さい場合ほど空気セルの空気量を略一定に維持する状態をより長く継続させることにより、空気セルの膨張状態が押圧力としてマッサージ対象となる身体に伝わる時間が十分に確保され、所定の押圧力で身体にマッサージ効果を確実に与えることができるという効果を有する。また、押圧力を最大とする第1の空気供給量モードの場合は、空気セルが最大膨張状態に達してもポンプを停止させずに動作継続させることにより、一般的に利用する最大押圧力でのマッサージ動作でポンプの制御が容易になり、ポンプへの負担を減らせると共に、空気セルへの空気供給開始時における空気セルの膨張の立上がりが速く、身体へのマッサージ効果を一層高められるという効果を有する。

BACKGROUND OF THE INVENTION
The present invention relates to a massager operation control method that controls supply and discharge of air to and from each air cell that expands and exhibits a massage effect in a massager, and appropriately adjusts the pressing force by the air cell.
[0002]
[Prior art]
Traditionally, massagers that give a predetermined massage effect to each part of the human body have been used in various shapes ranging from small ones that are held in hand to large ones such as chairs and mats. A variety of systems are employed for the operating mechanism, such as a system that generates mechanical movement and a system that uses expansion and contraction of a hollow body by a fluid.
[0003]
Among these conventional massagers, the pneumatic type that gives the body a massage effect by inflating a hollow air cell arranged at an appropriate location with air easily gives a massage effect to many parts of the body In addition, it has a feature that it is lighter than a mechanical type, can be easily folded and carried when not in use, and is convenient for storage. In this pneumatic massager, an air supply / discharge device that is provided separately from the massager body and supplies and discharges air to and from the massager body directly in contact with the body with an air cell built-in Are used in combination, and the air supply and discharge states are controlled respectively, and the air supply and discharge are repeatedly applied to intermittently apply pressure to the body. An example of such a pneumatic massager is shown in FIGS. FIG. 7 is a perspective view of a conventional massage device, and FIG. 8 is an explanatory diagram of an air supply / discharge operation state in the conventional massage device.
[0004]
A conventional massage device 100 shown in each of the drawings is a massage device main body 101 having a predetermined shape that comes into contact with a human body and gives a massage effect, and is accommodated in a predetermined position in the massage device main body 101 and is expanded by supplying and discharging air. A configuration including a plurality of air cells 102 that contract and an air supply / discharge device 103 that supplies and discharges air to and from the air cells 102.
[0005]
The air supply / discharge device 103 communicates the well-known pump 104 that sends air for expanding the air cell 102 at a predetermined pressure, the pump 104 and the air cell 102 in communication, and the air cell 102 and the outside. A plurality of switching valves 105 that can be switched between states, and a control unit 106 that controls each switching valve 105 to repeatedly supply and discharge air to each air cell 102 to perform expansion and contraction operations, respectively. The configuration (see FIG. 2).
[0006]
In this conventional massage device 100, when a person starts the operation of the air supply / discharge device 103 with the body in contact with the massage device body 101, the control unit 106 switches between supply and discharge of air to the air cell 102. By appropriately switching with the valve 105, the expansion and contraction of the air cell 102 are repeated, a pressing force is generated on the body at the time of expansion, and the pressing state is released at the time of contraction, so that a predetermined massage effect is achieved at the position of the air cell 102 of the massager body 101. Could be given.
[0007]
Adjustment of the pressing force from the air cell 102 to the body in the massage device 100 is performed by the control unit 106 of the air supply / discharge device 103 changing the switching timing of the switching valve 105, from the start of air supply to the air cell 102 until the start of air discharge. This is done by appropriately adjusting the period and changing the amount of air supplied into the air cell 102 to change the expansion state of the air cell 102. The standard is that the air cell 102 is expanded to the maximum, and when the air cell 102 is expanded to this maximum expansion state, the maximum pressing force that can be generated in the air cell 102 can be applied from the air cell 102 to the body. A state is reached (see FIG. 8A). When the pressing force in the maximum expansion state is too strong, the control unit 106 advances the switching timing of the switching valve 105 based on the user's operation and sets the air discharge state before the air cell 102 reaches the maximum expansion state. In addition, the amount of air supplied to the air cell 102 is suppressed to reduce the pressing force (see FIG. 8B).
[0008]
[Problems to be solved by the invention]
Since the adjustment of the pressing force of the conventional massage device has been performed as described above, if the air supply amount into the air cell 102 is suppressed by advancing the switching timing of the switching valve 105, the pressing force decreases, but the air cell As a result, the time when the pressure is transmitted to the body becomes too short and the body cannot be properly given a massage effect. Was.
[0009]
The present invention has been made to solve the above-described problems. Even when the air cell is inflated to be smaller than the maximum inflated state, the inflated state is maintained for a predetermined period so that a pressing force is appropriately applied to the body. It is an object of the present invention to provide a massager operation control method capable of giving a massage effect.
[0011]
[Means for Solving the Problems]
  The massage device operation control method according to the present invention includes an air cell formed of a hollow body having a predetermined shape that can be expanded and contracted, a pump that supplies air to the air cell, and the air cell and the pump. In a massager comprising one switching valve for switching a target communicating with an air cell to either a pump or a predetermined location other than the pump, and a control means for controlling the pump and the switching valve, The air supply state in which the air cell is communicated with the pump and the air discharge state in which the air cell is communicated with a predetermined location other than the pump are switched at a predetermined cycle, and from the start of the air supply state to the start of the air discharge state And an operation control method for setting a period for maintaining the air amount in the air cell substantially constant at least once, and switching between an air supply state and an air discharge state of the switching valve. Switching timing between ON and OFF states of the phases and / or the pumpControlDifferent air supply amount to the air cellA first air supply amount mode that maximizes the pressing force, and a second air supply amount mode that weakens the pressing force;And givingThe first air supply amount mode and the second air supply amount modeAbout the length of the period from the start of the air supply state to the start of the air discharge state.In the case of the first air supply mode, the operation is continued without stopping the pump even if the air cell reaches the maximum expansion state, and in the case of the second air supply mode, the air cell The period during which the air amount in the inside is maintained substantially constant is set longer as the air amount in the air cell in the state in which the air amount is substantially constant is smaller.Is. As described above, in the present invention, the air supply amount to the air cell is varied.1st and 2ndWhile the air supply amount mode is set, the length of the period from the start of air supply until the start of air discharge until the air cell is in a predetermined expansion state is made substantially the same regardless of the air supply amount mode,In the case of the second air supply amount mode in which the pressing force is weakened,The smaller the size of the expanded air cell, the longer the time it takes to transmit the expanded state of the air cell to the body to be massaged as a pressing force by continuing the state of maintaining the air volume of the air cell substantially constant. The massage effect can be reliably given to the body with a predetermined pressing force.Further, in the first air supply amount mode in which the pressing force is maximized, even if the air cell reaches the maximum expansion state, the operation is continued without stopping the pump, so that the generally used maximum pressing force is obtained. With this massage operation, the pump can be controlled easily, the burden on the pump can be reduced, and the rise of the expansion of the air cell at the start of the air supply to the air cell is quick, and the massage effect on the body can be further enhanced.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
(First embodiment of the present invention)
Hereinafter, a massage device operation control method according to a first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a perspective view of a massager to which a massager operation control method according to the present embodiment is applied, and FIG. 2 is a schematic configuration of an air supply / discharge device in the massager to which the massager operation control method according to the present embodiment is applied. FIG. 3 and FIG. 3 are explanatory views of the air supply / discharge operation state by the massage device operation control method according to the present embodiment.
[0014]
As shown in the drawings, the massage device 1 to which the operation control method according to the present embodiment is applied includes a massage device body 101, an air cell 102, and an air supply / discharge device 103, as in the conventional case. is there.
The air cell 102 is formed of a hollow body having a predetermined shape capable of expanding and contracting, and a predetermined pipe 107 serving as a communication path communicating with a hollow portion of the hollow body is connected to each of predetermined positions of the massage device main body 101. It is the structure arranged.
[0015]
Like the conventional air supply / discharge device 103, the air supply / discharge device 103 includes a pump 104, a switching valve 105, and a control unit 106. The pipe 107 is connected to each air cell 102. The air is repeatedly supplied or discharged through the pipe 107 to each air cell 102. The switching valve 105 switches between a state where the air cell 102 communicates with the pump 104 and a state where the air cell 102 communicates with the outside.
[0016]
The control unit 106 controls the pump 104 and the switching valves 105 to repeat the supply and discharge of air to the air cells 102 to perform expansion and contraction operations, respectively. The control unit 106 is provided with an operation unit (not shown) operated by the user as a separate body, and is instructed to start and end the operation, the strength of the pressing force, and the like by a predetermined operation.
[0017]
Next, the operation of the massage device according to the massage device operation control method according to the present embodiment will be described. First, when the user operates the operation unit (not shown) in the state where a predetermined part of the body is in contact with the massage body 101, the control unit 106 starts operating the pump 104, While sending out air, the predetermined switching valve 105 is controlled and the pump 104 and the air cell 102 are made to communicate with each other. In this state, air from the pump 104 is pressurized and injected into the air cell 102 via the switching valve 105 and the pipe 107 to expand the air cell 102, and the pressing force due to the expansion of the air cell 102 causes the massager body 101 to be expanded. (See FIG. 3; period t1).
[0018]
When a predetermined time has elapsed after starting the expansion of the air cell 102, the control unit 106 stops the pump 104 and stops supplying air from the pump 104 to the air cell 102. In this state, a part of the air in the air cell 102 returns to the pump 104 side through the pipe 107 and the switching valve 105, but most of the air remains in the air cell 102 and the air cell 102 remains in an expanded state. The state is maintained, and a predetermined pressing force is continuously applied to the body contact portion (see FIG. 3; period t2).
[0019]
Further, when the air supply is stopped and a predetermined time has elapsed, the control unit 106 newly controls the switching valve 105 to switch the air cell 102 to the outside (see FIG. 2). In this state, air is discharged from the air cell 102 through the pipe 107 and the switching valve 105, and the air cell 102 contracts to attenuate the pressing force and does not apply the pressing force to the body contact portion (FIG. 3). See; period t3). Thereafter, when the air cell 102 contracts and a predetermined time elapses, the control unit 106 sets the pump 104 in an operating state, switches the communication state in the switching valve 105, and supplies air to the air cell 102 from the pump 104. And
[0020]
In this way, the air supply, supply stop and discharge states are repeated in sequence for the air cell 102. Each time the air cell 102 expands, maintains a size for a predetermined period, and then contracts, thereby massaging. The target portion is intermittently pressed and stimulated at the position of the air cell 102 of the massage device main body 101 to give a massage effect.
The pressing force due to the expansion of the air cell 102 is adjusted by the period from the start of air supply to the pump stop that determines the amount of air supply from the pump 104 to the air cell 102, that is, the length of the air supply period. Based on the control, the control unit 106 controls the communication state of the switching valve 105 and the pump operation to set a plurality of air supply amount modes having different air supply amounts, and adjusts the air amount in the air cell 102 to The pressing force is set.
[0021]
When the pressing force is maximized as the first air supply amount mode (see FIG. 3A), the air cell 102 is expanded to the maximum expansion state by extending the air supply period (see FIG. 3A). Period t1). When this maximum expansion state is reached, the control unit 106 stops the pump 104 and stops the air supply to the air cell 102. After the air supply is stopped, the pressing force is applied to the body from the air cell 102 in the maximum expansion state until the start of air discharge by switching the switching valve 105 (see FIG. 3A; period t2). As the length of the period from the stop of air supply to the start of air discharge, for example, about 1 to 10 seconds is given.
[0022]
On the other hand, when the pressing force is weakened as the second air supply amount mode (see FIG. 3B), the timing at which the control unit 106 stops the pump 104 is advanced based on the pressing force adjusting operation by the user. Then, the pump 104 is stopped before the air cell 102 reaches the maximum expansion state, and the amount of air supplied to the air cell 102 is reduced from the maximum expansion state (see FIG. 3B; period t1). Until the air supply by the pump 104 is stopped and the air discharge is started (see FIG. 3B; period t2), the air cell 102 maintained at a predetermined air amount is weakened compared to the maximum expansion state. The pressing force will be applied to the body. However, the period from the stop of air supply to the start of air discharge (see FIG. 3B; period t2) is the same as the case of the maximum pressing force that expands the air cell 102 to the maximum expansion state (see FIG. 3A). The period during which the pressing force is applied from the air cell 102 to the body after the air supply is stopped is constant in any air amount mode, and the massage effect on the body is ensured.
[0023]
As described above, in the massager operation control method according to the present embodiment, the air supply amount to the air cell 102 is set in plural ways by changing the stop timing of the pump 104, while the air supply from the air cell 102 is stopped from the air supply stop. When the time from the stop of the pump 104 for determining the period until the start of discharge to the switching of the switching valve 105 is the same regardless of the amount of air supply, the size of the expanded air cell 102 is small, that is, the pressing force is weak However, since the pump 104 is stopped and the air amount of the air cell 102 is maintained for a predetermined period, the expanded state of the air cell 102 is applied to the body to be massaged as a pressing force even if the air supply amount changes. The transmission time is ensured uniformly, and the massage effect is appropriately applied to the body with the pressing force according to the air supply amount to the air cell 102. It can be obtained.
[0024]
(Second embodiment of the present invention)
A massage device operation control method according to a second embodiment of the present invention will be described with reference to FIG. FIG. 4 is an explanatory diagram of the air supply / discharge operation state by the massage device operation control method according to the present embodiment.
The massage device operation control method according to the present embodiment is similar to the first embodiment in that the control unit 106 of the air supply / discharge device 103 appropriately switches the operation state of the pump 104 and the switching valve 105 to air to the air cell 102. The supply, supply stop, and discharge states are repeated in turn, and the difference is that the period from the start of air supply to the air cell 102 to the start of air discharge is constant regardless of the amount of air supplied to the air cell 102. Is.
[0025]
The operation of the massage device according to the massage device operation control method according to this embodiment will be described. First, when the user operates the operation unit (not shown) in the state where a predetermined part of the body is in contact with the massage body 101, the control unit 106 starts operating the pump 104, While sending out air, the predetermined switching valve 105 is controlled and the pump 104 and the air cell 102 are made to communicate with each other. In this state, air from the pump 104 is pressurized and injected into the air cell 102 via the switching valve 105 and the pipe 107 to expand the air cell 102, and the pressing force due to the expansion of the air cell 102 causes the massager body 101 to be expanded. (See FIG. 4; period t1).
[0026]
When a predetermined time has elapsed after starting the expansion of the air cell 102, the control unit 106 stops the pump 104 and stops supplying air from the pump 104 to the air cell 102. In this state, a part of the air in the air cell 102 returns to the pump 104 side through the pipe 107 and the switching valve 105, but most of the air remains in the air cell 102 and the air cell 102 remains in an expanded state. The state is maintained, and a predetermined pressing force is continuously applied to the body contact portion (see FIG. 4; period t2).
[0027]
Further, when the air supply is stopped and a predetermined time has elapsed, the control unit 106 newly controls the switching valve 105 to switch the air cell 102 to the outside (see FIG. 2). In this state, air is discharged from the air cell 102 through the pipe 107 and the switching valve 105, and the air cell 102 contracts to attenuate the pressing force and does not apply the pressing force to the body contact portion (FIG. 4). See; period t3). Thereafter, when the air cell 102 contracts and a predetermined time elapses, the control unit 106 sets the pump 104 in an operating state, switches the communication state in the switching valve 105, and supplies air to the air cell 102 from the pump 104. And
[0028]
In this way, the air supply, supply stop and discharge states are repeated in sequence for the air cell 102. Each time the air cell 102 expands, maintains a size for a predetermined period, and then contracts, thereby massaging. The target portion is intermittently pressed and stimulated at the position of the air cell 102 of the massage device main body 101 to give a massage effect.
The pressing force due to the expansion of the air cell 102 is adjusted by the period from the start of air supply to the pump stop that determines the amount of air supply from the pump 104 to the air cell 102, that is, the length of the air supply period. Based on the control, the control unit 106 controls the communication state of the switching valve 105 and the pump operation to set a plurality of air supply amount modes having different air supply amounts, and adjusts the air amount in the air cell 102 to The pressing force is set.
[0029]
When the pressing force is maximized as the first air supply amount mode (see FIG. 4A), the air cell 102 is expanded to the maximum expansion state by extending the air supply period (see FIG. 4A). Period t1). When this maximum expansion state is reached, the control unit 106 stops the pump 104 and stops the air supply to the air cell 102. After the air supply is stopped, the pressing force is applied to the body from the air cell 102 in the maximum expansion state until the start of air discharge by switching the switching valve 105 (see FIG. 4A; period t2).
[0030]
On the other hand, when the pressing force is weakened as the second air supply amount mode (see FIG. 4B), the timing at which the control unit 106 stops the pump 104 is advanced based on the pressing force adjusting operation by the user. Then, the pump 104 is stopped before the air cell 102 reaches the maximum expansion state, and the air supply amount to the air cell 102 is reduced from the maximum expansion state (see FIG. 4B; period t1). Until the air supply by the pump 104 is stopped and the air discharge is started (see FIG. 4B; period t2), the air cell 102 maintained at a predetermined air amount is weakened compared to the maximum expansion state. The pressing force will be applied to the body. However, the period from the start of air supply to the air cell 102 until the start of air discharge (see FIG. 4B; t1 + t2) is the maximum pressing force that expands the air cell 102 to the maximum expansion state (see FIG. 4A). This is the same as that described above, and even after the air supply is stopped, a sufficient period for applying a pressing force to the body from the air cell 102 is ensured, and a massage effect corresponding to the pressing force is given to the body.
[0031]
As described above, in the massager operation control method according to the present embodiment, the air supply amount to the air cell 102 is set in plural ways by changing the stop timing of the pump 104, while the air supply from the start of air supply to the air cell 102 is changed to air. Assuming that the switching operation timing of the switching valve 105 for determining the period until the start of discharge is the same regardless of the difference in the air supply amount, the pump 104 is operated as the size of the expanded air cell 102 is smaller, that is, as the pressing force is weaker. Since the state of stopping and maintaining the air amount of the air cell 102 is continued for a longer time, even when the air supply amount decreases, the time for the expansion state of the air cell 102 to be transmitted to the body to be massaged as a pressing force is sufficient. It is ensured and a massage effect can be reliably given to the body with a pressing force according to the amount of air supplied to the air cell 102.
[0032]
(Third embodiment of the present invention)
A massager operation control method according to a third embodiment of the present invention will be described with reference to FIG. FIG. 5 is an explanatory diagram of the air supply / discharge operation state by the massage device operation control method according to the present embodiment.
The massaging device operation control method according to the present embodiment is similar to the second embodiment in that the control unit 106 of the air supply / discharge device 103 appropriately switches the operation state of the pump 104 and the switching valve 105 to change the air to the air cell 102. The supply, supply stop, and discharge states are repeated in order, while the difference is that when the air cell 102 is expanded to the maximum expansion state to maximize the pressing force, the air cell 102 is brought to the maximum expansion state. Even if it reaches, the operation is continued without stopping the pump 104.
[0033]
The operation of the massage device according to the massage device operation control method according to this embodiment will be described. First, as in the first embodiment, when the user operates the operation unit (not shown) and instructs to start the operation in a state where a predetermined body part is in contact with the massage device body 101, the control unit 106 Operates the pump 104 to start air delivery and operates the switching valve 105 to switch the communication state between the pump 104 and the air cell 102. As a result, air is injected from the pump 104 into the air cell 102 to expand the air cell 102, and the pressing force due to the expansion of the air cell 102 is transmitted to the body (see FIG. 5; period t1).
[0034]
Here, when the maximum pressing force can be obtained by the pressing force adjusting operation of the user (first air supply amount mode) (see FIG. 5A), the expansion of the air cell 102 is started. After a predetermined time has elapsed, the air cell 102 reaches the maximum expansion state, and no more air enters the air cell 102 even if the air supply from the pump 104 is continued. From reaching this maximum expansion state to the start of air discharge by switching the switching valve 105, a constant state in which the size does not change continues in the air cell 102, and during this time, the air cell 102 continues to apply pressure to the body ( See FIG. 5A; period t2).
[0035]
When a predetermined time elapses after the air cell 102 reaches the maximum expansion state, the control unit 106 controls the switching valve 105 to switch the air cell 102 to the outside. In this state, air is discharged from the air cell 102 through the pipe 107 and the switching valve 105, and the air cell 102 contracts to attenuate the pressing force and does not apply the pressing force to the body contact portion (FIG. 5). (A) Reference; period t3). Thereafter, when the air cell 102 contracts and a predetermined time elapses, the control unit 106 switches the communication state in the switching valve 105 so that air is supplied from the pump 104 to the air cell 102.
[0036]
In this way, each of the air supply and discharge states to the air cell 102 is repeated in turn, and each time the air cell 102 expands and maintains its size for a predetermined period of time, it contracts, and the body massage target location It is possible to give a massage effect by intermittently stimulating the pressure with the maximum pressing force. Note that, after the operation starts, the pump 104 continues the air delivery operation until the operation of the massager 1 as a whole is stopped regardless of the state of the air cell 102 unless the pressing force is adjusted.
[0037]
On the other hand, when the pressing force is weakened from the maximum pressing force by the user's pressing force adjusting operation (second air supply amount mode) (see FIG. 5B), the expansion of the air cell 102 is performed. After a predetermined time has elapsed since the start of the operation, the control unit 106 stops the pump 104 before setting the air cell 102 to the maximum expansion state. As in the first embodiment, after the pump 104 is stopped, a part of the air in the air cell 102 returns to the pump 104 side, but most of the air remains in the air cell 102. The air cell 102 is maintained at a predetermined amount of air smaller than that in the maximum expansion state, and the air cell 102 is in a state in which a pressing force weakened compared to the maximum expansion state is applied to the body (see FIG. 5B; period t2). ).
[0038]
Further, after the air supply is stopped and a predetermined time has elapsed, the control unit 106 controls the switching valve 105 to switch the air cell 102 to the outside. In this state, air is discharged from the air cell 102 through the pipe 107 and the switching valve 105, and the air cell 102 contracts to attenuate the pressing force and does not apply the pressing force to the body contact portion (FIG. 5). (B) Reference; period t3). The time from the start of air supply until switching to the air discharge state (see FIG. 5B; t1 + t2) is the maximum pressing force that expands the air cell 102 to the maximum expansion state (see FIG. 5A). ), And a sufficient period of time for applying a pressing force to the body while maintaining the amount of air in the air cell 102 after stopping the air supply is ensured, and an appropriate massage effect according to the pressing force is given to the body.
[0039]
Thereafter, when the air cell 102 contracts and a predetermined time elapses, the control unit 106 sets the pump 104 in an operating state, switches the communication state in the switching valve 105, and supplies air to the air cell 102 from the pump 104. And
In this way, the air supply, supply stop and discharge states are repeated in sequence for the air cell 102. Each time the air cell 102 expands, maintains a size for a predetermined period, and then contracts, thereby massaging. The target portion is intermittently pressed and stimulated with a predetermined pressing force to give a massage effect.
[0040]
Thus, in the massager operation control method according to the present embodiment, when the air cell 102 is expanded to the maximum expansion state to obtain the maximum pressing force, the pump 104 is operated as it is without stopping, and the air cell is operated. Since the state in which the air injection into the air cell 102 has reached the limit is used as a state in which the amount of air in the 102 is maintained substantially constant, the pump 104 can be controlled by a massaging operation with the maximum pressing force that is generally used. It becomes easy, the burden on the pump 104 can be reduced, and the rise of the expansion of the air cell 102 at the start of air supply to the air cell 102 is quick, and the massage effect on the body can be further enhanced.
[0041]
In the massager operation control method according to each of the second and third embodiments, the air supply state start timing and the air discharge state start timing are matched in each air supply amount mode for the air cell 102, and the air Although the length of the period from the start of the supply state to the start of the air discharge state is made equal, the present invention is not limited to this, and the air of the switching valve 105 is set when a plurality of air supply amounts to the air cell 102 are set. A plurality of timings for switching between the supply state and the air discharge state and / or switching timing between the ON state and the OFF state of the pump 104 are set, and each timing of starting the air supply state and starting the air discharge state, and starting the air supply state For example, as shown in FIG. 6, in the air cell 102, the length of the period from the time to the start of the air discharge state can be varied. The air discharge start timing by switching the switching valve 105 in a constant air volume state can be changed as appropriate for each air supply amount mode, and the duration of the pressing force transmitted from the air cell 102 to the body can be adjusted. It is possible to optimize the massage effect by appropriately making the pressing timing correspond to the strength of the pressing force.

【The invention's effect】
As aboveAccording to the present invention, the air supply amount to the air cell is varied.1st and 2ndWhile the air supply amount mode is set, the length of the period from the start of air supply until the start of air discharge until the air cell is in a predetermined expansion state is made substantially the same regardless of the air supply amount mode,In the case of the second air supply amount mode in which the pressing force is weakened,The smaller the size of the expanded air cell, the longer the time it takes to transmit the expanded state of the air cell to the body to be massaged as a pressing force by continuing the state of maintaining the air volume of the air cell substantially constant. And has an effect of reliably giving a massage effect to the body with a predetermined pressing force.Further, in the first air supply amount mode in which the pressing force is maximized, even if the air cell reaches the maximum expansion state, the operation is continued without stopping the pump, so that the generally used maximum pressing force is obtained. The massage control of the pump makes it easy to control the pump, reduces the burden on the pump, and the rise of the expansion of the air cell at the start of the air supply to the air cell is fast, which can further enhance the massage effect on the body Have
