【発明の属する技術分野】
本発明は施療子によりマッサージを行うマッサージ機に関するものである。
【０００２】
【従来の技術】
マッサージ機には各種のものが提供されているが、もみマッサージを行うことができるマッサージ機の一例の機構部を図５に示す。該機構部は椅子の背もたれやベッド内に配設されて、ピニオンＰの回転駆動で背もたれやベッドに沿って自走するもので、走行ガイド用のころ１９及び上記ピニオンＰを両端に備える走行軸の外周に回転駆動される主軸３が設けられて、主軸３に取り付けた偏心部２の外周面にアーム１３を遊転自在に取り付けており、一端側が施療子４の取付部となっているアーム１３の他端は自在継手を備えるリンク１４，１４を介してクランク軸１５に連結されている。上記偏心部２は主軸３に対して偏心しているだけでなく、軸に対して傾斜した状態で取り付けられており、このために主軸３の回転によってアーム１３先端の施療子４は三次元的な動きとなるもみマッサージ動作を行い、クランク軸１５を回転させればアーム１３先端の施療子４はたたきマッサージ動作を行い、さらに走行軸を回転させれば、上記自走に伴って施療子４は人体背面をさするさすりマッサージを行う。また、ねじ軸１６を回転駆動することにより、主軸３の軸方向における施療子４，４の位置を変更して幅調整をすることができ、リンク１８を介してクランク軸１５の位置を変更することで、施療子４，４の前後方向位置を変えて強弱調整（突出量調整）を行うことができるようになっている。なお、上記機構部は特公平１−４９４９６号公報などに示されたものと同じであり、上記もみマッサージ動作の際の施療子４の背後から見た動きＭｘ及び側方から見た動きＭｙは、共に図４に示すような楕円形軌跡を描くものとなっている。
【０００３】
なお、上記の動きを行わせるためのモータは、図中のボックス内に納められて、その出力は複数の電動クラッチ２１，２２，２３を介して主軸３やクランク軸、ねじ軸１６等に伝達される。また上記モータは正逆回転を切り替えることができるために、もみマッサージにしても、モータの回転方向Ａ，Ｂによって、その動きは逆向きとなる。図中５はモータやクラッチ２１，２２，２３の動作制御を行う制御部である。
【０００４】
【発明が解決しようとする課題】
しかし、上記のマッサージ機における幅調整や強弱調整及び上下移動は、施療子４，４を使用者の好みの位置に合わせるために設けられたものであり、施療子４によるもみマッサージ動作そのものは、主軸３に設けた偏心部２の偏心量と傾きに依存する一定の軌跡を描くものとなっており、幅広くマッサージしたいという要望や、前後移動量が大きくてより強いマッサージを得たいという要望には応えることができなかった。
【０００５】
本発明はこのような点に鑑みなされたものであって、その目的とするところは多種多様なマッサージ動作を簡便に得ることができるマッサージ機を提供するにある。
【０００６】
【課題を解決するための手段】
しかして本発明は、回転駆動される主軸に設けた偏心部の偏心量と該偏心部の主軸に対する傾きとによって施療子にマッサージ動作となる楕円形軌跡を描く周期的運動を行わせる駆動部と、該駆動部の動作を制御する制御部とを備えているマッサージ機において、上記駆動部に加えて施療子の幅方向位置を変更する幅位置変更手段を備えるとともに、施療子の上記周期的運動に幅位置変更手段による幅位置変更の往復動作を同期連動させて行わせる制御部を備え、該制御部は、施療子の周期的運動の１周期に幅位置変更の複数回の往復動作を同期連動させて複数回の幅方向変化を重畳させた楕円形軌跡を施療子に描かせるものであることに第１の特徴を有している。

また本発明は、回転駆動される主軸に設けた偏心部の偏心量と該偏心部の主軸に対する傾きとによって施療子にマッサージ動作となる楕円形軌跡を描く周期的運動を行わせる駆動部と、該駆動部の動作を制御する制御部とを備えているマッサージ機において、上記駆動部に加えて施療子の突出方向位置を変更する突出量変更手段を備えるとともに、施療子の上記周期的運動に突出量変更手段による突出量変更の往復動作を同期連動させて行わせる制御部を備え、該制御部は、施療子の周期的運動の１周期に突出量変更の複数回の往復動作を同期連動させて上記複数回の突出量変化を重畳させた楕円形軌跡を施療子に描かせるものであることに第２の特徴を有してる。
【０００８】
また本発明は、回転駆動される主軸に設けた偏心部の偏心量と該偏心部の主軸に対する傾きとによって施療子にマッサージ動作となる楕円形軌跡を描く周期的運動を行わせる駆動部と、該駆動部の動作を制御する制御部とを備えているマッサージ機において、上記駆動部に加えて施療子の上下方向位置を変更する上下位置変更手段を備えるとともに、施療子の上記周期的運動に上下位置変更手段による上下位置変更の往復動作を同期連動させて行わせる制御部を備え、該制御部は、施療子の周期的運動の１周期に上下位置変更の複数回の往復動作を同期連動させて上記複数回の上下位置変更を重畳させた楕円形軌跡を施療子に描かせるものであることに第３の特徴を有している。
【０００９】
【発明の実施の形態】
以下本発明を実施の形態の一例に基づいて詳述すると、マッサージ機の機構部としては、上記従来例で示したものと同じでよいが、この機構部のモータやクラッチ２１，２２，２３の動作制御を行う制御部５として、もみマッサージのための主軸３の回転駆動と、幅位置調整のためのねじ軸１６の往復回転駆動とを同時に且つ同期させて行うことができるものを用いる。
【００１０】
そして、主軸３の１回転（施療子４のもみマッサージ動作の１周期）に対してねじ軸１６の１往復回転を同期連動させるとともに、もみ動作において幅が広がる方向に施療子４を移動させる時に幅位置調整における幅を広くする動作が生じるようにしたならば、主軸３の回転による主軸３の軸方向における施療子４の図１(a)にＭｘ（図４参照）で示す幅方向移動軌跡に、ねじ軸１６の往復回転駆動によるところの施療子４の上記軸方向における１往復移動Ｗが重畳されることから、施療子４が描く軌跡は図１(a)にＭｘＷで示す幅広のものとなる。
【００１１】
また、主軸３の１回転に対してねじ軸１６の複数回の往復回転を同期連動させたならば、施療子４の図１(b)にＭｘで示す幅方向移動軌跡に、ねじ軸１６の複数回の往復回転駆動によるところの施療子４の上記軸方向の複数回の往復移動Ｗ２が重畳されることから、施療子４が描く軌跡は図１(b)にＭｘＷ２で示す左右に振れながらの楕円軌道となる。
【００１２】
また、ねじ軸１６の往復回転による１往復運動の間に主軸３を複数回転させて複数周期を同期連動させたならば、図１(c)に示すように、移動軌跡Ｍｘと往復移動Ｗとの重畳結果はＭｘＷ３で示すものとなる。
【００１３】
もみマッサージのための主軸３の回転駆動と、クランク軸１５の位置を変更させることによる前後の突出量変更動作とを同時に且つ同期させて行うことができるようにしてもよい。
【００１４】
今、主軸３の１回転に対して突出量変更の１往復動作を同期連動させるとともにもみ動作において前方に施療子４を移動させる際に突出量変更によるところの前方移動が組み合わされるようにしたならば、主軸３の回転による主軸３の軸方向と直交する方向における施療子４の図２(a)にＭｙ（図４参照）で示す前後方向移動軌跡に、突出量変更の１往復動作によるところの施療子４の上記方向における動きＴが重畳されることから、施療子４が描く軌跡は図２(a)にＭｙＴで示す前後移動量の大きいものとなる。
【００１５】
また、主軸３の１回転に対して突出量変更の複数回の往復動作を同期連動させたならば、図２(b)に示すように施療子４の前後方向移動軌跡Ｍｙに突出量変更の複数回の往復動作によるところの施療子４の上記方向における動きＴが重畳されることから、施療子４が描く軌跡は図２(b)にＭｙＴ２で示す前後に振れながらの全体として前後に移動する楕円形軌跡となる。
【００１６】
また、突出量変更の１往復動作の間に主軸を複数回転させて複数周期を同期連動させたならば、図２(c)に示すように、移動軌跡Ｍｙと往復移動Ｔとの重畳結果はＭｙＴ３で示すものとなる。
【００１７】
もみマッサージのための主軸３の回転駆動と、ピニオンＰの往復回転駆動による上下往復動とを同時に且つ同期させて行うことができるようにしてもよく、主軸３の１回転に対して上下方向の１往復動作を同期連動させたならば、主軸３の回転による主軸３の軸方向及び上下方向における施療子４の図３(a)にＭｘで示す移動軌跡に、上下移動動作Ｕが重畳されることから、施療子４が描く軌跡は図３(a)にＭｘＵで示す上下移動量の大きいものとなる。
【００１８】
また、主軸３の１回転に対して複数回の上下往復動作を同期連動させたならば、図３(b)に示すように施療子４の上下左右方向の移動軌跡Ｍｘに上下の往復動Ｕが重畳されることから、施療子４が描く軌跡は図３(b)にＭｘＵ２で示す上下に振れながらの楕円形軌跡となる。
【００１９】
また、上下方向の１往復動作の間に主軸３を複数回転させて複数周期を同期連動させたならば、図３(c)に示すように、移動軌跡Ｍｘと往復移動Ｕとの重畳結果はＭｘＵ３で示すものとなる。
【００２０】
なお、主軸３の回転駆動のためのモータと、ねじ軸１６の回転駆動のためのモータや、突出量変更用のモータ、上下移動のためのモータは、別にしておくことが望ましいが、ねじ軸１６や突出量変更駆動部やピニオンＰへの回転動力伝達経路中に回転方向を切り換える手段を設けておくのであれば、共通のモータで上記のものを駆動するようにしてもよい。上記の各駆動を夫々独立したモータで行う場合には、たとえば主軸３の回転角を検出する検出手段や突出量の検出手段、幅位置の検出手段等を設けて、同期がとれるようにしておく。
【００２１】
また、幅位置調整の動作と突出量変更の動作と上下位置変更動作のうちの少なくとも２つを主軸３の回転に同期連動させたならば、さらに多様なマッサージを得ることができるのはもちろんである。
【００２２】
【発明の効果】

[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail based on an example of the embodiment. The mechanism part of the massage machine may be the same as that shown in the above-described conventional example. As the control unit 5 that performs operation control, a controller that can simultaneously and synchronously perform rotational driving of the main shaft 3 for massaging and reciprocating rotational driving of the screw shaft 16 for width position adjustment is used.
[0010]
When the reciprocating rotation of the screw shaft 16 is synchronously interlocked with one rotation of the main shaft 3 (one cycle of the massage massage operation of the treatment element 4), and the treatment element 4 is moved in a direction in which the width increases in the kneading operation. If an operation to increase the width in the width position adjustment is generated, the movement trace of the treatment element 4 in the axial direction of the main shaft 3 due to the rotation of the main shaft 3 is indicated by Mx (see FIG. 4) in FIG. Further, since the reciprocating movement W in the axial direction of the treatment element 4 due to the reciprocating drive of the screw shaft 16 is superimposed, the locus drawn by the treatment element 4 has a wide width indicated by MxW in FIG. It becomes.
[0011]
Further, if a plurality of reciprocating rotations of the screw shaft 16 are synchronized with one rotation of the main shaft 3, the screw shaft 16 moves in the width direction movement locus indicated by Mx in FIG. A plurality of reciprocating movements W2 in the axial direction of the treatment element 4 due to a plurality of reciprocating rotational drivings are superimposed, so that the trajectory drawn by the treatment element 4 swings to the left and right indicated by MxW2 in FIG. Becomes an elliptical orbit.
[0012]
Further, if the main shaft 3 is rotated a plurality of times during a single reciprocating motion by the reciprocating rotation of the screw shaft 16, and a plurality of cycles are synchronously linked, as shown in FIG. The result of superimposing is indicated by MxW3.
[0013]
You may enable it to perform simultaneously and synchronously the rotational drive of the main axis | shaft 3 for a massage massage, and the protrusion amount change operation before and behind by changing the position of the crankshaft 15. FIG.
[0014]
Now, if one reciprocating operation of changing the projection amount is synchronized with one rotation of the main shaft 3 and the treatment element 4 is moved forward in the kneading operation, the forward movement due to the changing projection amount is combined. For example, the treatment element 4 in the direction orthogonal to the axial direction of the main shaft 3 due to the rotation of the main shaft 3 is moved by a reciprocating operation of changing the protrusion amount in the longitudinal movement locus indicated by My (see FIG. 4) in FIG. Since the movement T of the treatment element 4 in the above direction is superimposed, the locus drawn by the treatment element 4 has a large amount of forward and backward movement indicated by MyT in FIG.
[0015]
Further, if a plurality of reciprocating movements for changing the protrusion amount are synchronized with one rotation of the main shaft 3, the protrusion amount is changed in the longitudinal movement locus My of the treatment element 4 as shown in FIG. 2 (b). Since the movement T in the above-mentioned direction of the treatment element 4 due to the reciprocating motion is superimposed, the locus drawn by the treatment element 4 moves back and forth as a whole while swinging back and forth as indicated by MyT2 in FIG. It becomes an elliptical locus .
[0016]
In addition, if the main shaft is rotated a plurality of times during one reciprocating operation for changing the protrusion amount and a plurality of cycles are synchronized with each other, the result of superimposing the movement locus My and the reciprocating movement T as shown in FIG. This is indicated by MyT3.
[0017]
The rotational drive of the main shaft 3 for the massage treatment and the vertical reciprocation by the reciprocating rotational drive of the pinion P may be performed simultaneously and synchronously. If one reciprocating operation is synchronized and interlocked, the vertical movement operation U is superimposed on the movement locus indicated by Mx in FIG. 3A of the treatment element 4 in the axial direction and the vertical direction of the main shaft 3 due to the rotation of the main shaft 3. Therefore, the locus drawn by the treatment element 4 has a large vertical movement amount indicated by MxU in FIG.
[0018]
If a plurality of up and down reciprocating motions are synchronously linked to one rotation of the main shaft 3, as shown in FIG. Therefore, the locus drawn by the treatment element 4 becomes an elliptical locus while swinging up and down as indicated by MxU2 in FIG.
[0019]
If the main shaft 3 is rotated a plurality of times during one reciprocating motion in the vertical direction and a plurality of cycles are synchronously interlocked, as shown in FIG. 3C, the result of superimposing the movement locus Mx and the reciprocating movement U is This is indicated by MxU3.
[0020]
It is desirable that the motor for rotating the main shaft 3, the motor for rotating the screw shaft 16, the motor for changing the protrusion amount, and the motor for moving up and down are separated from each other. If a means for switching the rotation direction is provided in the rotational power transmission path to the shaft 16, the protrusion amount changing drive unit, and the pinion P, the above-described one may be driven by a common motor. When each of the above driving is performed by independent motors, for example, a detecting means for detecting the rotation angle of the main shaft 3, a detecting means for the protruding amount, a detecting means for the width position, etc. are provided so as to be synchronized. .
[0021]
Further, if at least two of the width position adjusting operation, the protrusion amount changing operation, and the vertical position changing operation are synchronized with the rotation of the main shaft 3, it is possible to obtain more various massages. is there.
[0022]

Therefore, to obtain an operation in which a reciprocating operation of changing the width position is superimposed on a periodic motion that draws an elliptical locus determined by the amount of eccentricity of the eccentric portion provided on the rotationally driven main shaft and the inclination of the eccentric portion with respect to the main shaft. Therefore, it is possible to obtain a massaging operation rich in changes in the width direction, which has not been obtained conventionally.
