　特許文献１などに開示される従来のマッサージ機においては、左右一対のマッサージ部材によるマッサージ動作と押圧部材によるマッサージ動作とは、常に同じ動作パターンの組み合わせとして足部に施されるものであった。そのため、得られるマッサージ感が単一的になっていた。
  また、左右のマッサージ部材が足部を左右両側から狭持・押圧した後に、この狭持状態を緩めようとするタイミングで、押圧部材が足部を押圧したとしても、足部が押圧部材から離れる方向へ逃げてしまい、押圧部材によるマッサージ動作が十分に足部に伝わらないということもあり、押圧部材による効果的なマッサージ動作がなされないこともあった。 In the conventional massage machine disclosed in Patent Literature 1 and the like, the massage operation by the pair of left and right massage members and the massage operation by the pressing member are always applied to the foot as a combination of the same operation patterns. Therefore, the massage feeling obtained was united.
In addition, after the left and right massage members sandwich and press the foot from both the left and right sides, even if the pressing member presses the foot at the timing to loosen the holding state, the foot separates from the pressing member.

　本実施形態の下肢用マッサージ機１は、正面視すると四角形であり側面視すると長靴型（Ｌ字型）であるケーシング２を有している。このケーシング２の前面には、前方及び上方へ向けて開放する左右一対の施療凹部９が、互いに左右に離れて並設されている。これら左右の施療凹部９内には、弾力性及び柔軟性があり且つ適度な通気性を備えた内張材が設けられている。 In the present specification, “calf” refers to a portion above the ankle that comes under the knee, and “foot” refers to a portion below the ankle. Moreover, the direction in description is shown suitably in the figure, and corresponds with the front-back direction, the left-right direction, and the up-down direction seen from the user who uses the massage machine 1 for lower limbs.
The lower limb massage machine 1 of the present embodiment has a casing 2 that is rectangular when viewed from the front and boots (L-shaped) when viewed from the side. On the front surface of the casing 2, a pair of left and right treatment recesses 9 that are open frontward and upward are provided side by side apart from each other. In these left and right treatment recesses 9, there is provided a lining material which is elastic and flexible and has an appropriate air permeability.
　図２に示すように、ケーシング２内には、台フレーム部２ａと、この台フレーム部２ａの後端部で起立する背フレーム部を有する側面視Ｌ型の支持フレームが設けられている。台フレーム部２ａには水平マッサージ機構３が設けられており、背フレーム部には垂直マッサージ機構４が設けられている。
　なお、水平マッサージ機構３や垂直マッサージ機構４の「水平」「垂直」の呼称は、本明細書中での便宜上のものに過ぎず、下肢用マッサージ機１としての使用状態を限定したものではない。 As shown in FIG. 2, a side view L-shaped support frame having a base frame portion 2a and a back frame portion standing at a rear end portion of the base frame portion 2a is provided in the casing 2. A horizontal massage mechanism 3 is provided on the base frame portion 2a, and a vertical massage mechanism 4 is provided on the back frame portion.
In addition, the names of “horizontal” and “vertical” of the horizontal massage mechanism 3 and the vertical massage mechanism 4 are merely for convenience in the present specification, and do not limit the use state as the lower limb massage machine 1. .
　まず、水平マッサージ機構３（足部マッサージ機構）を説明する。
　図２～図５などに示すように、水平マッサージ機構３は、足部を嵌め入れる程度に左右方向に離れて並設された左右一対のマッサージ部材５，５と、これら左右一対のマッサージ部材５，５の相互間に配備された押圧部材６と、左右一対のマッサージ部材５，５を互いに近接離反させる第１駆動機構７と、押圧部材６を動作させる第２駆動機構８とを有している。 First, the horizontal massage mechanism 3 (foot massage mechanism) will be described.
As shown in FIG. 2 to FIG. 5 and the like, the horizontal massage mechanism 3 includes a pair of left and right massage members 5 and 5 arranged in parallel in the left and right direction so as to fit a foot portion, and the pair of left and right massage members 5. , 5, a first drive mechanism 7 that moves the pair of left and right massage members 5, 5 close to and away from each other, and a second drive mechanism 8 that operates the press member 6. Yes.
　マッサージ部材５，５は左右一対を一組として、この組み合わせがケーシング２の左右の施療凹部９に対応するように合計二組、設けられている。マッサージ部材５は、厚み方向に弾性を有する素材によって起立した板状に形成され、マッサージ部材５が互いに対向する内面には、足部への接触感を和らげるクッション材やカバー材等が設けられている。
　水平マッサージ機構３の第１駆動機構７は、左右一対のマッサージ部材５，５を、それらの相互間に嵌め入れられる足部への挟持位置（図４参照）と、解放位置（図３参照）との間で往復動作させることにより、足部に対して揉みによるマッサージ動作を付与するものである。この第１駆動機構７は、二組のマッサージ部材５，５を同時に駆動させるようになっている。 The massage members 5 and 5 are provided as a pair of left and right, and a total of two sets are provided so that this combination corresponds to the left and right treatment recesses 9 of the casing 2. The massage member 5 is formed in a plate-like shape standing by a material having elasticity in the thickness direction, and a cushioning material, a cover material or the like that softens the feeling of contact with the foot is provided on the inner surface where the massage member 5 faces each other. Yes.
The first drive mechanism 7 of the horizontal massage mechanism 3 has a pair of left and right massage members 5, 5 sandwiched between them (see FIG. 4) and a release position (see FIG. 3). By reciprocating between the foot and the foot, a massage operation by itchiness is imparted to the foot. This 1st drive mechanism 7 drives two sets of massage members 5 and 5 simultaneously.
  第１駆動機構７は、マッサージ部材５，５間を貫通する方向（左右方向）に設けられた１本の回転軸１０と、この回転軸１０を回転駆動する駆動モータ１１（電動モータ）と、回転軸１０の回転駆動力をマッサージ部材５によるマッサージ動作に変換するための変換部とを有している。
　駆動モータ１１は、正転駆動と逆転駆動とに切換可能なもので、ウォームギアとこのウォームギアに噛合するウォームホイルとが内蔵された減速部を介して、回転軸１０に回転駆動力を伝達する。 The first drive mechanism 7 includes one rotary shaft 10 provided in a direction (left-right direction) penetrating between the massage members 5 and 5, a drive motor 11 (electric motor) that rotationally drives the rotary shaft 10, And a conversion unit for converting the rotational driving force of the rotary shaft 10 into a massage operation by the massage member 5.
The drive motor 11 can be switched between forward rotation drive and reverse rotation drive, and transmits the rotational drive force to the rotary shaft 10 via a speed reducing portion in which a worm gear and a worm wheel meshing with the worm gear are incorporated.
　変換部は、回転軸１０がマッサージ部材５を貫通する部分に配備されており、回転軸１０が中心部を貫通し、外周縁に回転軸１０に対して傾斜状に設けられたカム溝を有する傾斜ボス部１３を有している。
　本実施形態の場合、傾斜ボス部１３と回転軸１０との間には、ワンウエイクラッチ機構１４が配備されるものとなっている。それ故、駆動モータ１１が正転駆動し、回転軸１０が正転する場合には、回転軸１０の回転駆動力が傾斜ボス部１３に伝えられ、回転軸１０と傾斜ボス部１３とは同方向に一体に回転する。一方、駆動モータ１１が逆転駆動し、回転軸１０が逆転する場合には、傾斜ボス部１３は回転軸１０に対して空転状態となり、回転軸１０の回転駆動力は傾斜ボス部１３には伝わらないことになる。 The conversion unit is provided in a portion where the rotary shaft 10 penetrates the massage member 5, the rotary shaft 10 passes through the center portion, and has a cam groove provided on the outer peripheral edge so as to be inclined with respect to the rotary shaft 10. An inclined boss portion 13 is provided.
In the present embodiment, a one-way clutch mechanism 14 is provided between the inclined boss portion 13 and the rotating shaft 10. Therefore, when the drive motor 11 rotates forward and the rotating shaft 10 rotates forward, the rotational driving force of the rotating shaft 10 is transmitted to the inclined boss portion 13, and the rotating shaft 10 and the inclined boss portion 13 are the same. Rotate integrally in the direction. On the other hand, when the drive motor 11 is driven in the reverse direction and the rotary shaft 10 is rotated in the reverse direction, the inclined boss portion 13 is idle with respect to the rotary shaft 10, and the rotational driving force of the rotary shaft 10 is transmitted to the inclined boss portion 13. There will be no.
　なお、ワンウエイクラッチ機構１４の詳細は、後述する。
　傾斜ボス部１３の外周縁には、マッサージ部材５の基端に設けられた環状嵌合部１５がベアリングを介して嵌り込んでおり、マッサージ部材５は回転軸１０と相対回転自在な状態を保持するようになっている。
　また、変換部は、マッサージ部材５から下向きに突出する規制突起１６を、支持フレームの台フレーム部２ａ等に設けられた左右方向に長い横長孔１７に係合させる構造を有している。この規制突起１６と横長孔１７とが係合し、規制突起１６が横長孔１７内を摺動することにより、マッサージ部材５は、傾斜ボス部１３と供回り（従動回転）しないようになっている。すなわち、回転軸１０が回転する際には、傾斜ボス部１３が回転軸１０のまわりに傾斜成分に応じた左右方向の揺動を起こすようになって、このときの揺動成分だけがマッサージ部材５に伝達されるようになっている。 Details of the one-way clutch mechanism 14 will be described later.
An annular fitting portion 15 provided at the base end of the massage member 5 is fitted to the outer peripheral edge of the inclined boss portion 13 via a bearing, and the massage member 5 maintains a state of being rotatable relative to the rotary shaft 10. It is supposed to be.
Further, the conversion portion has a structure in which a regulation protrusion 16 protruding downward from the massage member 5 is engaged with a horizontally elongated hole 17 provided in the base frame portion 2a of the support frame in the left-right direction. The restricting protrusion 16 and the horizontally long hole 17 engage with each other, and the restricting protrusion 16 slides in the horizontally long hole 17, so that the massage member 5 does not rotate with the inclined boss portion 13 (followed rotation). Yes. That is, when the rotating shaft 10 rotates, the inclined boss portion 13 swings in the left-right direction around the rotating shaft 10 according to the tilt component, and only the swing component at this time is a massage member. 5 is transmitted.
　回転軸１０に対して傾斜ボス部１３が傾く傾斜方向は、マッサージ部材５，５間において相対逆向きとなるように設定されている。そのため、左右一対のマッサージ部材５，５が互いに近接した後、離反するといった揺動動作を行う。左右一対のマッサージ部材５，５が互いに近接した際には、マッサージ部材５，５間に配備された足部を挟持し、左右から押圧マッサージするといった動作が行われることになる。 The inclination direction in which the inclined boss portion 13 is inclined with respect to the rotating shaft 10 is set to be in the opposite direction between the massage members 5 and 5. Therefore, after the pair of left and right massage members 5 and 5 come close to each other, a swinging operation is performed such that they are separated. When the pair of left and right massage members 5 and 5 are close to each other, an operation is performed in which a foot portion disposed between the massage members 5 and 5 is sandwiched and massaged by pressing from the left and right.
　左右一対のマッサージ部材５，５が互いに離反した際には、マッサージ部材５，５間に配備された足部が開放されることとなる。回転軸１０を連続回転させることで、マッサージ部材５，５は前述した挟持動作と解放動作とを交互に繰り返しながら、所定角度範囲に規制された状況下でうねり状の揺動をする。
　上記した動作は、回転軸１０を正転した際に発生する動きである。すなわち、回転軸１０を正転した際には、ワンウエイクラッチ機構１４により、回転軸１０の回転駆動力が傾斜ボス部１３に伝えられ、回転軸１０と傾斜ボス部１３とは同方向に一体に回転し、マッサージ部材５が揺動駆動されることになる。 When the pair of left and right massage members 5 and 5 are separated from each other, the foot portion provided between the massage members 5 and 5 is opened. By continuously rotating the rotary shaft 10, the massage members 5 and 5 swing in a wavy manner under a condition restricted to a predetermined angle range while alternately repeating the above-described sandwiching operation and releasing operation.
The above-described operation is a movement that occurs when the rotating shaft 10 is rotated forward. That is, when the rotary shaft 10 is rotated forward, the one-way clutch mechanism 14 transmits the rotational driving force of the rotary shaft 10 to the inclined boss portion 13, and the rotary shaft 10 and the inclined boss portion 13 are integrated in the same direction. The massage member 5 is driven to swing by rotating.
　一方、回転軸１０が逆転した際には、ワンウエイクラッチ機構１４により、傾斜ボス部１３は回転軸１０に対して空転状態となり、回転軸１０の回転駆動力は傾斜ボス部１３には伝わらない。そのため、マッサージ部材５は、足部の挟持状態、又は足部の解放状態を維持したまま停止するが、後述する押圧部材６は駆動されることになる。
　一方、図２や図５に示す如く、足裏への押圧マッサージを行う押圧部材６は、第１駆動機構７に備えられた回転軸１０に対して一体回転可能に設けられた回転ロータ２０と、この回転ロータ２０の外周面で、互いに周方向及び軸方向に所定間隔をおいて分散配置された複数の突起を有している。 On the other hand, when the rotating shaft 10 is rotated in the reverse direction, the one-way clutch mechanism 14 causes the inclined boss portion 13 to idle with respect to the rotating shaft 10, and the rotational driving force of the rotating shaft 10 is not transmitted to the inclined boss portion 13. For this reason, the massage member 5 stops while maintaining the clamped state of the foot part or the released state of the foot part, but the pressing member 6 described later is driven.
On the other hand, as shown in FIG. 2 and FIG. 5, the pressing member 6 that performs pressure massage on the soles is provided with a rotary rotor 20 provided so as to be integrally rotatable with respect to the rotary shaft 10 provided in the first drive mechanism 7. The outer surface of the rotary rotor 20 has a plurality of protrusions dispersedly arranged at predetermined intervals in the circumferential direction and the axial direction.
　この押圧部材６を駆動する第２駆動機構８は、回転ロータ２０を回転軸１０と一体回転させることにより、左右一対のマッサージ部材５，５の相互間に嵌め入れられる足部に対して、その足裏（つま先裏、土踏まず、踵裏）を上方へ押圧するようにマッサージ動作を付与するものである。
  回転軸１０の回転により回転ロータ２０を回転させるとき、回転軸１０の回転方向に応じて、複数の突起が足部の足裏を押圧しながら後側から前側へ移動するか、反対に前側から後側へと移行するかを選択できるものとなっている。 The second drive mechanism 8 that drives the pressing member 6 is configured so that the rotary rotor 20 rotates integrally with the rotary shaft 10 so that the foot part fitted between the pair of left and right massage members 5 and 5 is A massage operation is applied so as to press the sole (toe, arch, heel) upward.
When the rotary rotor 20 is rotated by the rotation of the rotary shaft 10, the plurality of protrusions move from the rear side to the front side while pressing the soles of the feet according to the rotation direction of the rotary shaft 10, or from the front side. It is possible to select whether to move to the rear side.
　本実施形態の場合、足裏への押圧マッサージを行う押圧部材６は、更に複雑な構成を有するものとなっている。
　本実施形態の押圧部材６は、使用者の足裏中央部をマッサージする第１マッサージ部材２０を有すると共に、使用者の足裏後部をマッサージする第２マッサージ部材２１と、使用者の足裏前部をマッサージする第３マッサージ部材２２とを有し、これら第１マッサージ部材２０～第３マッサージ部材２２を連動して駆動させることで、足裏に対するマッサージ動作を発生させるものとされている。 In the case of this embodiment, the pressing member 6 that performs pressure massage on the sole has a more complicated configuration.
The pressing member 6 of the present embodiment includes a first massage member 20 that massages the user's sole center part, a second massage member 21 that massages the user's sole, and the user's sole. And a third massage member 22 for massaging the portion. The first massage member 20 to the third massage member 22 are driven in conjunction with each other to generate a massage operation on the sole.
　第１マッサージ部材２０は、足裏中央部に押圧マッサージを付与する、前述した回転ロータ２０である。
　この第１マッサージ部材２０（回転ロータ）から後方に延びるように形成されたアーム状の第１連結片２３が配備されていて、第１連結片２３は、基端部が回転軸１０に対して偏心状態で回動自在に取り付けられ、先端部に第２マッサージ部材２１が設けられていて、回転軸１０が回転運動することで、第１連結片２３に連結されている第２マッサージ部材２１が揺動運動する構成とされている。 The 1st massage member 20 is the rotary rotor 20 mentioned above which gives a press massage to the sole center part.
An arm-shaped first connecting piece 23 formed so as to extend rearward from the first massage member 20 (rotating rotor) is provided, and the first connecting piece 23 has a base end portion with respect to the rotating shaft 10. The second massage member 21 is attached in an eccentric state so as to be rotatable, the second massage member 21 is provided at the tip, and the rotary shaft 10 is rotated to move the second massage member 21 connected to the first connection piece 23. It is configured to swing.
　加えて、第１マッサージ部材２０（回転ローラ）から前方に延びるように形成されたアーム状の第２連結片２４が配備されていて、第２連結片２４は、基端部が回転軸１０に対して偏心状態で回動自在に取り付けられ、先端部に第３マッサージ部材２２が設けられていて、回転軸１０が回転運動することで、第２連結片２４に連結されている第３マッサージ部材２２が前後方向にスライド揺動する構成とされている。 In addition, an arm-shaped second connecting piece 24 formed to extend forward from the first massage member 20 (rotating roller) is provided, and the second connecting piece 24 has a base end portion on the rotating shaft 10. On the other hand, the third massaging member is attached in an eccentric state so as to be rotatable, the third massaging member 22 is provided at the tip, and the rotary shaft 10 is rotated to be coupled to the second coupling piece 24. 22 is configured to slide and swing in the front-rear direction.
　第２マッサージ部材２１と第３マッサージ部材２２には、上方突出状に複数の突起２５が形成されており、この突起により足裏へのマッサージが効果的なものとなる。
　上記した第１連結片２３と第２連結片２４は、それぞれの連結片の基端部が同じ位置となるように、一体に形成されている。
　前述した如く、本実施形態の下肢用マッサージ機１の場合、傾斜ボス部１３と回転軸１０との間には、ワンウエイクラッチ機構１４が配備されるものとなっている。 A plurality of protrusions 25 are formed on the second massage member 21 and the third massage member 22 so as to protrude upward, and these protrusions effectively massage the soles of the feet.
The first connecting piece 23 and the second connecting piece 24 described above are integrally formed so that the base ends of the connecting pieces are at the same position.
As described above, in the case of the lower limb massage machine 1 of this embodiment, the one-way clutch mechanism 14 is provided between the inclined boss portion 13 and the rotary shaft 10.
　このワンウエイクラッチ機構１４は、一方向動力伝達部４０と、ブレーキ部５０とから構成されている。
　図６、図７に示す如く、一方向動力伝達部４０は、傾斜ボス部１３の幅方向内側に設けられており、図６、図８に示す如く、ブレーキ部５０は、傾斜ボス部１３の幅方向外側に設けられている。 The one-way clutch mechanism 14 includes a one-way power transmission unit 40 and a brake unit 50.
As shown in FIGS. 6 and 7, the one-way power transmission portion 40 is provided on the inner side in the width direction of the inclined boss portion 13. As shown in FIGS. 6 and 8, the brake portion 50 is connected to the inclined boss portion 13. It is provided outside in the width direction.
　図６、図７に示すように、一方向動力伝達部４０は、傾斜ボス部１３の内部に遊嵌状態で嵌り込む蝸状ボス部４２を有している。蝸状ボス部４２は、回転軸１０が中心部を貫通しており、回転軸１０に対して固定され同伴回転するようになっている。
　蝸状ボス部４２の外周縁には、側方視で螺旋状のカム溝４３が形成されている。詳しくは、このカム溝４３は、角度０度の位置で半径が最大であり、反時計方向に廻るにしたがって、半径が短くなるようなカム溝４３となっている。そのため、丁度一周回った位置（角度３６０度）の直前では、半径が最短となっている。このため、角度３６０度（言い換えれば、角度０度）の位置には、切り立った崖部４４（位置規制部）が形成されていることになる。このカム溝４３は、側面視で、蝸牛の殻状に似た形態を呈している。この崖部４４は、それぞれのマッサージ部材５において、回転軸１０の周方向に対して所定の位置に形成されるものとなっている。 As shown in FIGS. 6 and 7, the one-way power transmission unit 40 has a hook-shaped boss portion 42 that fits into the inclined boss portion 13 in a loosely fitted state. The hook-shaped boss portion 42 has the rotating shaft 10 penetrating the center portion, and is fixed to the rotating shaft 10 and rotates together.
A spiral cam groove 43 is formed on the outer peripheral edge of the bowl-shaped boss portion 42 in a side view. Specifically, the cam groove 43 is a cam groove 43 having a maximum radius at a position of an angle of 0 degrees and a radius becoming shorter as it rotates counterclockwise. For this reason, the radius is the shortest immediately before the position that has just made one round (angle 360 degrees). For this reason, a steep cliff 44 (position restricting portion) is formed at a position of an angle of 360 degrees (in other words, an angle of 0 degrees). The cam groove 43 has a form resembling a cochlear shell shape in a side view. The cliff 44 is formed at a predetermined position in each massage member 5 with respect to the circumferential direction of the rotary shaft 10.
　例えば、右足を挟み込む押圧部材５に対応する崖部４４の位置と、左足を挟み込む押圧部材５に対応する崖部４４の位置とを、回転軸１０の周方向に対して同じ位置とすることで、右足を挟持押圧する際に同じように左足も挟持押圧することができるようになる。すなわち、右足に対応する押圧部材５と、左足に対応する押圧部材５とが同位相で揺動させることができる。一方で、右足を挟み込む押圧部材５に対応する崖部４４の位置と、左足を挟み込む押圧部材５に対応する崖部４４の位置とを、回転軸１０の周方向に対して９０度乃至は１８０度ずらすことにより、例えば、右足（左足）押圧する際に、左足（右足）を緩めた状態乃至は解放状態とすることができるようになる。すなわち、右足に対応する押圧部材５と、左足に対応する押圧部材５とを異なった位相で揺動させることが可能となる。 For example, the position of the cliff 44 corresponding to the pressing member 5 that sandwiches the right foot and the position of the cliff 44 corresponding to the pressing member 5 that sandwiches the left foot are set to the same position with respect to the circumferential direction of the rotating shaft 10. When the right foot is clamped and pressed, the left foot can be clamped and pressed in the same manner. That is, the pressing member 5 corresponding to the right foot and the pressing member 5 corresponding to the left foot can be swung in the same phase. On the other hand, the position of the cliff 44 corresponding to the pressing member 5 that sandwiches the right foot and the position of the cliff 44 corresponding to the pressing member 5 that sandwiches the left foot are 90 degrees or 180 degrees with respect to the circumferential direction of the rotary shaft 10. By shifting the degree, for example, when the right foot (left foot) is pressed, the left foot (right foot) can be released or released. That is, the pressing member 5 corresponding to the right foot and the pressing member 5 corresponding to the left foot can be swung at different phases.
　この蝸状ボス部４２のカム溝４３上を、位置決め片４５の下端底部が摺動することになる。この位置決め片４５は、角柱状の形状を呈しており、長手方向が蝸状ボス部４２の半径方向を向くものとされている。一方で、位置決め片４５の上端部は、傾斜ボス部１３の幅方向内側（蝸状ボス部４２に面する側）であって、径外側に設けられた径方向を向く溝部４６に嵌り込んでいて、当該溝部４６内を径方向に摺動自在となっている。 The bottom end of the positioning piece 45 slides on the cam groove 43 of the bowl-shaped boss 42. The positioning piece 45 has a prismatic shape, and its longitudinal direction faces the radial direction of the bowl-shaped boss portion 42. On the other hand, the upper end portion of the positioning piece 45 is fitted in a groove portion 46 which is on the inner side in the width direction of the inclined boss portion 13 (the side facing the bowl-shaped boss portion 42) and faces the radial direction provided on the outer diameter side. The groove 46 is slidable in the radial direction.
　図７に示す分解状態の部材を組み付けた場合、傾斜ボス部１３の径方向内側に形成された円筒状の凹部４７に、蝸状ボス部４２が遊嵌状態に嵌り込むこととなり、蝸状ボス部４２のカム溝４３上を位置決め片４５が摺動すると共に、傾斜ボス部１３の溝部４６に位置決め片４５の上端部が嵌り込んだ構成となっている。
　この構成であれば、回転軸１０が正転方向（図７の方向から蝸状ボス部４２を見て、蝸状ボス部４２が時計回りに廻る方向）に回転すると、蝸状ボス部４２に形成された崖部４４が、位置決め片４５の下端部の側面に当接し、蝸状ボス部４２と位置決め片４５が同伴回転することとなる。言い換えれば、回転軸１０の正転回転と同伴して、位置決め片４５も正転方向に回転する。 When the disassembled member shown in FIG. 7 is assembled, the hook-like boss portion 42 is fitted into the cylindrical concave portion 47 formed on the radially inner side of the inclined boss portion 13 in a loose-fitting state. The positioning piece 45 slides on the cam groove 43 of the portion 42, and the upper end portion of the positioning piece 45 is fitted in the groove portion 46 of the inclined boss portion 13.
With this configuration, when the rotary shaft 10 rotates in the forward rotation direction (the direction in which the hook-shaped boss portion 42 rotates clockwise when viewed from the direction of FIG. 7), the hook-shaped boss portion 42 The formed cliff portion 44 comes into contact with the side surface of the lower end portion of the positioning piece 45, and the bowl-shaped boss portion 42 and the positioning piece 45 rotate together. In other words, the positioning piece 45 also rotates in the forward direction along with the forward rotation of the rotating shaft 10.
　この際、位置決め片４５の上端部は、傾斜ボス部１３の溝部４６に嵌り込んだ構成となっているため、回転軸１０が正転するに伴い、傾斜ボス部１３も正転方向に回転し、ひいては、その回転駆動力により、マッサージ部材５が揺動駆動されることになる。
　一方、回転軸１０が逆転方向（図７の方向から蝸状ボス部４２を見て、蝸状ボス部４２が反時計回りに廻る方向）に回転すると、位置決め片４５は、蝸状ボス部４２に形成された崖部４４と係合することはなく、蝸状ボス部４２のカム溝４３上をスライドするようになる。位置決め片４５が崖部４４に達した際、すなわち、蝸状ボス部４２における角度０度から角度３６０度に到る際には、位置決め片４５が崖部４４を落下するように動くことになる。 At this time, since the upper end portion of the positioning piece 45 is fitted into the groove portion 46 of the inclined boss portion 13, the inclined boss portion 13 also rotates in the forward direction as the rotary shaft 10 rotates forward. As a result, the massage member 5 is driven to swing by the rotational driving force.
On the other hand, when the rotary shaft 10 rotates in the reverse direction (the direction in which the hook-shaped boss portion 42 rotates counterclockwise when the hook-shaped boss portion 42 is viewed from the direction of FIG. 7), the positioning piece 45 is moved to the hook-shaped boss portion 42. It does not engage with the cliff portion 44 formed in the above-mentioned shape, and slides on the cam groove 43 of the bowl-shaped boss portion 42. When the positioning piece 45 reaches the cliff 44, that is, when the angle from the angle 0 degree to 360 degrees in the bowl-shaped boss part 42 is reached, the positioning piece 45 moves so as to fall on the cliff 44. .
　このことから明らかなように、回転軸１０が逆転方向に回転する際には、崖部４４が位置決め片４５の下端部の側面に当接することはなく、位置決め片４５は、蝸状ボス部４２のカム溝４３上を滑るだけとなり、蝸状ボス部４２と位置決め片４５が同伴回転しないこととなる。そのため、回転軸１０が逆転回転する際には、その回転駆動力は、位置決め片４５に伝達することはなく、傾斜ボス部１３は非回転状態となる。そのため、マッサージ部材５は揺動運動せず、停止した状態となる。 As is clear from this, when the rotary shaft 10 rotates in the reverse direction, the cliff portion 44 does not come into contact with the side surface of the lower end portion of the positioning piece 45, and the positioning piece 45 has the bowl-shaped boss portion 42. Only the cam groove 43 slides, and the hook-shaped boss portion 42 and the positioning piece 45 do not rotate together. Therefore, when the rotating shaft 10 rotates in the reverse direction, the rotational driving force is not transmitted to the positioning piece 45, and the inclined boss portion 13 is not rotated. Therefore, the massage member 5 does not swing and is stopped.
　上記した一方向動力伝達部４０により、マッサージ部材５の揺動状態と停止状態が切り替えられることになる。
　ところで、マッサージ部材５が停止状態の場合、言い換えれば、回転軸１０が逆転していて、位置決め片４５の下端部が蝸状ボス部４２のカム溝４３上を滑っている状態の場合、マッサージ部材５に負荷を加えると、傾斜ボス部１３を介して、位置決め片４５の下端部が蝸状ボス部４２のカム溝４３上を反時計回りに勝手に動き得る状況となって、マッサージ部材５が意図せず動くようになる。 The oscillating state and the stopped state of the massage member 5 are switched by the above-described unidirectional power transmission unit 40.
By the way, when the massage member 5 is in a stopped state, in other words, when the rotating shaft 10 is reversed and the lower end portion of the positioning piece 45 is sliding on the cam groove 43 of the bowl-shaped boss portion 42, the massage member When a load is applied to 5, the lower end portion of the positioning piece 45 can move freely on the cam groove 43 of the bowl-shaped boss portion 42 via the inclined boss portion 13. It will move unintentionally.
　例えば、マッサージ部材５，５を近接させた状態（足部を挟み込んだ状態）で、回転軸１０を正転から逆転に切り替え、マッサージ部材５を停止させたとしても、挟み込んだ足部からの反力により、マッサージ部材５に負荷が加わり、マッサージ部材５が離反する方向に動くこととなる。
　このような不都合を防ぐために、ワンウエイクラッチ機構１４には、傾斜ボス部１３を逆転方向に回転させないためのブレーキ部５０が設けられている。 For example, even if the massaging members 5 and 5 are close to each other (a state where the foot is sandwiched), the rotation shaft 10 is switched from normal rotation to reverse rotation and the massage member 5 is stopped. Due to the force, a load is applied to the massage member 5 and the massage member 5 moves in a direction away from the massage member 5.
In order to prevent such inconvenience, the one-way clutch mechanism 14 is provided with a brake portion 50 for preventing the inclined boss portion 13 from rotating in the reverse direction.
　図８に示す如く、ブレーキ部５０は、傾斜ボス部１３の幅方向外側に、取り付けリング５５を用いて取り付けられたブレーキインナー部５１と、このブレーキインナー部５１の外周部を取り囲むように取り付けられ、且つケーシング（固定側）に固定されるブレーキアウター部５２を有する。ブレーキアウター部５２は、環状（円筒状）の部材であり、このブレーキアウター部５２の内側空間にブレーキインナー部５１が遊嵌状に嵌り込む。 As shown in FIG. 8, the brake portion 50 is attached to the outer side in the width direction of the inclined boss portion 13 so as to surround the brake inner portion 51 attached using the attachment ring 55 and the outer peripheral portion of the brake inner portion 51. And a brake outer portion 52 fixed to the casing (fixed side). The brake outer portion 52 is an annular (cylindrical) member, and the brake inner portion 51 is fitted into the inner space of the brake outer portion 52 in a loose fit.
　ブレーキインナー部５１は環状の部材であり、外周面には、側面視で直角三角形の形状を呈した三角凸部５３が、ブレーキインナー部５１の外周方向に沿って複数個（本実施形態の場合、８個）形成されている。三角凸部５３の頂点近傍では、ブレーキアウター部５２の内周面との距離（隙間）が非常に狭くなるが、三角凸部５３の谷部近傍では、ブレーキアウター部５２の内周面との距離（隙間）が広くなるようになっている。 The brake inner portion 51 is an annular member, and a plurality of triangular convex portions 53 having a right triangle shape in a side view are provided on the outer peripheral surface along the outer peripheral direction of the brake inner portion 51 (in the case of the present embodiment). 8). In the vicinity of the apex of the triangular convex portion 53, the distance (gap) from the inner peripheral surface of the brake outer portion 52 is very narrow, but in the vicinity of the trough portion of the triangular convex portion 53, the distance from the inner peripheral surface of the brake outer portion 52 is reduced. The distance (gap) is increased.
　加えて、ブレーキインナー部５１とブレーキアウター部５２との間、言い換えれば、三角凸部５３の谷部には、当該谷部内を移動可能とされた隙間部材５４が配設されている。この隙間部材５４は、球状、乃至は円柱状を呈する部材であり、その大きさ（直径）は、三角凸部５３の頂点とブレーキアウター部５２の内周面との隙間よりは大きなものとされている。 In addition, a gap member 54 that is movable in the valley portion is disposed between the brake inner portion 51 and the brake outer portion 52, in other words, in the valley portion of the triangular convex portion 53. The gap member 54 is a member having a spherical shape or a cylindrical shape, and its size (diameter) is larger than the gap between the apex of the triangular convex portion 53 and the inner peripheral surface of the brake outer portion 52. ing.
　以上述べた構成を有するブレーキ部５０によれば、回転軸１０が正転方向（図８の方向からブレーキインナー部５１を見て、ブレーキインナー部５１が反時計回りに廻る方向）に回転すると、隙間部材５４は、三角凸部５３間に形成された谷部に位置することとなり、ブレーキインナー部５１とブレーキアウター部５２との間を連結するものが全くない状態となる。そのため、ブレーキインナー部５１とブレーキアウター部５２とは非連結状態となり、ブレーキ部５０としての作用を発現しないものとなる。そのため、傾斜ボス部１３の回転を阻害することが無く、マッサージ部材５は確実に揺動駆動されることになる。 According to the brake unit 50 having the above-described configuration, when the rotary shaft 10 rotates in the forward rotation direction (the direction in which the brake inner unit 51 rotates counterclockwise when viewed from the direction of FIG. 8), The gap member 54 is located in a valley formed between the triangular protrusions 53, and there is no connection between the brake inner part 51 and the brake outer part 52. Therefore, the brake inner part 51 and the brake outer part 52 are in a non-connected state, and the action as the brake part 50 is not exhibited. Therefore, the massage member 5 is reliably driven to swing without hindering the rotation of the inclined boss portion 13.
　逆に、回転軸１０が逆転方向（図８の方向からブレーキインナー部５１を見て、ブレーキインナー部５１が時計回りに廻る方向）に回転すると、隙間部材５４は三角凸部５３の斜面を登り、三角凸部５３の頂点近傍に達することになる。三角凸部５３の頂点近傍に達した隙間部材５４は、三角凸部５３（言い換えれば、ブレーキインナー部５１）とブレーキアウター部５２との隙間に噛み込み、ブレーキインナー部５１とブレーキアウター部５２とが一体回転するように働きかける。 Conversely, when the rotary shaft 10 rotates in the reverse direction (the direction in which the brake inner portion 51 turns clockwise when viewed from the direction of the brake inner portion 51 from the direction of FIG. 8), the gap member 54 climbs the slope of the triangular convex portion 53. Thus, the vicinity of the apex of the triangular convex portion 53 is reached. The gap member 54 that has reached the vicinity of the apex of the triangular convex portion 53 is engaged with the gap between the triangular convex portion 53 (in other words, the brake inner portion 51) and the brake outer portion 52, and the brake inner portion 51 and the brake outer portion 52 are Work to rotate as a unit.
　この状態になると、ブレーキインナー部５１は、固定側（例えばケーシング）につながるブレーキアウター部５２と連結状態になるため、ブレーキインナー部５１が非回転状態となる。そのため、ブレーキインナー部５１に連結された傾斜ボス部１３の回転が阻害され、マッサージ部材５は、その位置において動きが抑制されることとなる。
　このようなブレーキ部５０の作用により、マッサージ部材５，５を近接させた状態（足部を挟み込んだ状態）で、回転軸１０を正転から逆転に切り替え、マッサージ部材５を停止させたとしても、挟み込んだ足部からの反力により、マッサージ部材５が離反する方向に動くことを確実に抑制することが可能となる。 If it will be in this state, since the brake inner part 51 will be in the connection state with the brake outer part 52 connected to a fixed side (for example, casing), the brake inner part 51 will be in a non-rotation state. Therefore, the rotation of the inclined boss portion 13 connected to the brake inner portion 51 is hindered, and the movement of the massage member 5 is suppressed at that position.
Even if the massaging members 5 and 5 are brought close to each other by such an action of the brake unit 50 (a state where the foot is sandwiched), the rotation shaft 10 is switched from normal rotation to reverse rotation and the massaging member 5 is stopped. It becomes possible to reliably suppress the massage member 5 from moving in the direction of separating by the reaction force from the sandwiched foot.
　加えて、下肢用マッサージ機１は、垂直マッサージ機構４（ふくらはぎマッサージ機構）を備えている。
　この垂直マッサージ機構４としては、様々なものが採用可能であるが、本実施形態の場合、図１に示すように、垂直マッサージ機構４は、ふくらはぎの前面の斜め外方及び内側方を押すマッサージ部材３０と、ふくらはぎを裏側からマッサージする押圧部材３１と、これらマッサージ部材３０と押圧部材３１とを一体に上下動させる昇降駆動部３２とを有するものとなっている。 In addition, the lower limb massage machine 1 includes a vertical massage mechanism 4 (calf massage mechanism).
As this vertical massage mechanism 4, various types can be adopted. In the case of this embodiment, as shown in FIG. 1, the vertical massage mechanism 4 is a massage that pushes diagonally outward and inward of the front of the calf. It has the member 30, the press member 31 which massages a calf from the back side, and the raising / lowering drive part 32 which moves these massage members 30 and the press member 31 up and down integrally.
　マッサージ部材３０と押圧部材３１とを一組として、この組み合わせがケーシング２の左右の施療凹部９に対応するように合計二組、設けられている。マッサージ部材３０と押圧部材３１とが一体となって上下動することで、ふくらはぎは、その前後が効果的に押圧マッサージされることになる。
　次に、本実施形態に係る下肢用マッサージ機１（特に、水平マッサージ機構３）の作動態様を説明する。 A total of two sets of the massage member 30 and the pressing member 31 are provided so as to correspond to the left and right treatment recesses 9 of the casing 2. When the massage member 30 and the pressing member 31 are integrally moved up and down, the front and rear of the calf are effectively pressed and massaged.
Next, an operation mode of the lower limb massage machine 1 (particularly, the horizontal massage mechanism 3) according to the present embodiment will be described.
　まず、下肢用マッサージ機１は、運転操作スイッチ３３がオフの状態にあるとき、水平マッサージ機構３における左右一対のマッサージ部材５は解放状態となっている。また、垂直マッサージ機構４のマッサージ部材５及び押圧部材６は、最も下方位置で停止している。
　そこでまず、使用者は、左右のふくらはぎを垂直マッサージ機構４におけるマッサージ部材５と押圧部材６との間に嵌め入れると共に、左右の足部を、水平マッサージ機構３における左右一対のマッサージ部材５の間に嵌め入れる。 First, in the lower limb massage machine 1, when the driving operation switch 33 is in an OFF state, the pair of left and right massage members 5 in the horizontal massage mechanism 3 are in a released state. Moreover, the massage member 5 and the pressing member 6 of the vertical massage mechanism 4 are stopped at the lowest position.
Therefore, first, the user inserts the left and right calves between the massage member 5 and the pressing member 6 in the vertical massage mechanism 4 and the left and right feet between the pair of left and right massage members 5 in the horizontal massage mechanism 3. Fit in.
　この状態で運転操作スイッチ３３をオン操作すると、駆動モータ１１が作動し、垂直マッサージ機構４では、マッサージ部材３０がふくらはぎの側面を押圧すると共に、押圧部材３１がふくらはぎの後面を押圧して、これら前後の押圧位置が同時に上方乃至は下方へ移動するような押圧マッサージが施される。
　また、水平マッサージ機構３では、駆動モータ１１の作動で回転軸１０が正転回転を始める。回転軸１０の正転の場合、ワンウエイクラッチ機構１４が動力伝達状態となり、回転軸１０の回転駆動力が傾斜ボス部１３に伝えられ、回転軸１０と傾斜ボス部１３とは同方向に一体に回転する。 When the operation switch 33 is turned on in this state, the drive motor 11 is activated, and in the vertical massage mechanism 4, the massage member 30 presses the side surface of the calf, and the pressing member 31 presses the rear surface of the calf. A pressing massage is performed so that the front and rear pressing positions simultaneously move upward or downward.
Further, in the horizontal massage mechanism 3, the rotation shaft 10 starts normal rotation by the operation of the drive motor 11. In the case of normal rotation of the rotating shaft 10, the one-way clutch mechanism 14 is in a power transmission state, the rotational driving force of the rotating shaft 10 is transmitted to the inclined boss portion 13, and the rotating shaft 10 and the inclined boss portion 13 are integrated in the same direction. Rotate.
　これにより、第１駆動機構７では変換部を介して左右一対のマッサージ部材５，５が左右に揺動し、解放状態と挟持状態とを繰り返すようになって、足部に対して左右両側から揉みマッサージを施すようになる。また同時に、第２駆動機構８により、押圧部材６（第１マッサージ部材２０～第３マッサージ部材２２）が駆動され、足部の足裏に対して押圧マッサージが施される。 As a result, in the first drive mechanism 7, the pair of left and right massage members 5 and 5 swings left and right via the conversion unit, and repeats the released state and the sandwiched state, so that the foot part can be viewed from both the left and right sides. Start massaging massage. At the same time, the pressing member 6 (the first massage member 20 to the third massage member 22) is driven by the second drive mechanism 8, and the pressure massage is performed on the soles of the feet.
　このような状況下で、自動運転モードのプログラム又は手動により、回転軸１０を逆転するようにする。特に、マッサージ部材５が近接した状態をセンサ（回転センサや近接センサ、リミットスイッチ）などで検出し、足部の挟持状態のタイミングで、回転軸１０を正転駆動から逆転駆動するようにする。
　すると、ワンウエイクラッチ機構１４（特に、一方向動力伝達部４０）が動力非伝達状態となり、回転軸１０の回転駆動力が傾斜ボス部１３に伝えられず、左右一対のマッサージ部材５，５が足部の狭持状態を維持したまま停止することになる。しかしながら、第２駆動機構８により、押圧部材６（第１マッサージ部材２０～第３マッサージ部材２２）が駆動され、足部の足裏に対して押圧マッサージはそのまま継続されることになる。 Under such circumstances, the rotating shaft 10 is reversed by a program in the automatic operation mode or manually. In particular, the state in which the massage member 5 is close is detected by a sensor (rotation sensor, proximity sensor, limit switch) or the like, and the rotary shaft 10 is driven in reverse from the normal rotation drive at the timing of the foot clamp state.
Then, the one-way clutch mechanism 14 (particularly, the one-way power transmission unit 40) is in a power non-transmission state, the rotational driving force of the rotating shaft 10 is not transmitted to the inclined boss part 13, and the pair of left and right massage members 5, 5 are It will stop while maintaining the holding state of the part. However, the pressing member 6 (the first massage member 20 to the third massage member 22) is driven by the second driving mechanism 8, and the pressing massage is continued as it is against the sole of the foot.
　このとき、ワンウエイクラッチ機構１４に備えられたブレーキ部５０の作用により、マッサージ部材５，５を近接させた状態（足部を挟み込んだ状態）で維持することができ、挟み込んだ足部からの反力により、マッサージ部材５が離反する方向に動くことを確実に抑制できる。
  このようにして、回転軸１０を逆転させ、ワンウエイクラッチ機構１４の動作（動力非伝達動作）を利用することで、左右一対のマッサージ部材５，５は挟持状態を保持することができる。この狭持状態を維持しつつ、押圧部材６、すなわち第１マッサージ部材２０～第３マッサージ部材２２を連動して駆動させることで、左右一対のマッサージ部材５，５の間に嵌め込まれた足部は、押圧部材６による押圧で上方に逃げるようなことがなく、押圧部材６による押圧を確実且つ十分に受けることができるようになる。 At this time, the action of the brake part 50 provided in the one-way clutch mechanism 14 allows the massage members 5 and 5 to be maintained in a state of being close to each other (a state in which the foot part is sandwiched), and the reaction from the sandwiched foot part. The force can reliably suppress the massage member 5 from moving in a direction away from the massage member 5.
In this way, the pair of left and right massage members 5 and 5 can be held in a sandwiched state by reversing the rotating shaft 10 and utilizing the operation (power non-transmission operation) of the one-way clutch mechanism 14. While maintaining this pinching state, the pressing member 6, that is, the first massage member 20 to the third massage member 22 are driven in conjunction with each other, so that the foot fitted between the pair of left and right massage members 5, 5 Does not escape upward due to the pressing by the pressing member 6, and the pressing by the pressing member 6 can be reliably and sufficiently received.
　すなわち、下肢用マッサージ機１を用いることで、左右一対のマッサージ部材５，５及び押圧部材６による足部への効果的なマッサージ施術が可能となる。
　ところで、今回開示された実施形態はすべての点で例示であって制限的なものではないと考えられるべきである。本発明の範囲は上記した説明ではなくて特許請求の範囲によって示され、特許請求の範囲と均等の意味および範囲内でのすべての変更が含まれることが意図される。 That is, by using the lower limb massage machine 1, it is possible to effectively massage the foot by the pair of left and right massage members 5, 5 and the pressing member 6.
By the way, it should be thought that embodiment disclosed this time is an illustration and restrictive at no points.

　例えば、垂直マッサージ機構４と水平マッサージ機構３とは、常に同期して動作するようにしてもよいし、いずれか一方だけを独立して動作するようにしてもよい。これらは、使用者の所望するところに応じて、適宜選択できるようにしておくとよい。 For example, the vertical massage mechanism 4 and the horizontal massage mechanism 3 may always operate in synchronization, or only one of them may operate independently. These may be appropriately selected according to the user's desire.
