前記駆動機構部60は、傾動軸53に相対回動可能に支持されて配設され、この傾動軸53を中心に傾動可能とされるものであり、詳細には、傾動軸53に回動可能として取付けられるハウジング61と、このハウジング61内に設けられ、揉み玉51に揉み動作を行わせるための駆動力を与える揉みモータ62と、同じくハウジング61内に設けられ、揉み玉51に叩き動作を行わせるための駆動力を与える叩きモータ64と、ハウジング61内でこれら揉みモータ62、叩きモータ64からの運動を揉み玉51に伝達する揉み機構及び叩き機構とを備える構成である。   The drive mechanism 60 is disposed to be supported by the tilting shaft 53 so as to be rotatable relative to the tilting shaft 53, and can be tilted about the tilting shaft 53. And a housing motor 62 provided in the housing 61 for applying a driving force for causing the kneading balls 51 to perform a kneading operation, and also provided in the housing 61 for striking the kneading balls 51. A tapping motor 64 that gives a driving force to perform, a kneading motor 62 in the housing 61, a kneading mechanism that transmits the movement from the tapping motor 64 to the kneading balls 51, and a tapping mechanism.

この駆動機構部60が、揉み玉51が取付けられた揉み玉支持アーム52を可動状態で支持しつつ、ベース部54に対し傾動軸53を中心に傾動可能とされることで、揉み玉51を背もたれ部上の被施療者に対し進退させ、揉み玉51の被施療者側への突出量を調整できる仕組みである。こうした駆動機構部60の傾動のために、ハウジング61の側部には、傾動軸53を中心とする所定ピッチ円径で且つ所定円弧長の部分歯車67が固定配設される。また、揉みモータ62と叩きモータ64は、それぞれ制御部40から出力される制御信号を受けて作動し、揉み玉51による各種マッサージ機能を被施療者に対して提供することとなる。   The drive mechanism 60 is capable of tilting around the tilting shaft 53 with respect to the base portion 54 while supporting the kneading ball support arm 52 to which the kneading balls 51 are attached in a movable state. This is a mechanism that allows the user on the backrest part to advance and retreat and adjust the amount of protrusion of the kneading balls 51 toward the user. In order to tilt the drive mechanism 60, a partial gear 67 having a predetermined pitch circle diameter and a predetermined arc length around the tilt shaft 53 is fixedly disposed on the side of the housing 61. The kneading motor 62 and the tapping motor 64 operate in response to control signals output from the control unit 40, and provide various massage functions by the kneading balls 51 to the user.

駆動機構部60の前記揉み機構としては、ハウジング61内で傾動軸53上に回動可能に支持され、揉みモータ62で回転駆動される揉み軸部63と、この揉み軸部63上に形成された偏心ロータ部63aに相対回動可能として取付けられる揉み玉支持アーム52とを備える構成である。なお、揉み玉支持アーム52は、揉み軸部63に支持される部位から揉み玉取付位置までの長さを、少なくとも揉み玉51及び駆動機構部60が最大限傾動した状態で、被施療者が背もたれ部13にもたれた場合の被施療者の背面位置、及び駆動機構部60における最も被施療者寄りの位置をそれぞれ揉み玉51が越えて突出可能となる寸法として形成される。
また、駆動機構部60の前記叩き機構としては、ハウジング61内に傾動軸53と平行な向きで回動可能として配設される叩き軸65と、この叩き軸65上に形成された偏心ロータ部65aに一端部を相対回動可能に取付られると共に、他端部を揉み玉支持アーム52の一部に揺動可能に取付けられるロッド66と、叩きモータ64の駆動力を叩き軸65に伝達する原動プーリ64a、伝動ベルト64b、及び従動プーリ64cとを備える構成である。
The stagnation mechanism of the drive mechanism unit 60 is formed on the stagnation shaft portion 63 and a stagnation shaft portion 63 that is rotatably supported on the tilting shaft 53 in the housing 61 and is rotationally driven by the squeezing motor 62. The kneading ball support arm 52 is attached to the eccentric rotor portion 63a so as to be relatively rotatable. The kneading ball support arm 52 has a length from the portion supported by the kneading shaft portion 63 to the kneading ball mounting position, with at least the kneading balls 51 and the drive mechanism 60 tilted to the maximum extent by the user. The size is such that the kneading balls 51 can protrude beyond the back position of the user when leaning against the backrest 13 and the position closest to the user in the drive mechanism 60.
Further, as the hitting mechanism of the drive mechanism portion 60, a hitting shaft 65 disposed in a housing 61 so as to be rotatable in a direction parallel to the tilting shaft 53, and an eccentric rotor portion formed on the hitting shaft 65. One end portion is attached to 65a so as to be relatively rotatable, and the other end portion is attached to a part of the kneading ball support arm 52 so as to be swingable, and the driving force of the tapping motor 64 is transmitted to the tapping shaft 65. This configuration includes a driving pulley 64a, a transmission belt 64b, and a driven pulley 64c.

前記揉み機構では、揉みモータ62の回転が減速機構(図示を省略)を介して揉み軸部63に伝えられ、揉み軸部63が回転することで、揉み軸部63上で傾動軸53に対し斜め向きとなっている偏心ロータ部63aが傾動軸53の周りで偏心した回転を行い、この偏心ロータ部63a周りに取付けられた揉み玉支持アーム52が、叩き機構側のロッド66との連結による拘束を受けつつ、偏心ロータ部63aの回転で連続して揺れる状態となる。これに伴い、揉み玉支持アーム52の一端部に取付けられた揉み玉51が連続する軌跡を描きつつ上下、左右及び前後に揺動することで、施療動作としての揉みを実現する仕組みである。   In the stagnation mechanism, the rotation of the stagnation motor 62 is transmitted to the stagnation shaft part 63 via a speed reduction mechanism (not shown), and the stagnation shaft part 63 rotates to rotate the stagnation shaft part 63 with respect to the tilting shaft 53. The eccentric rotor portion 63a which is inclined is rotated eccentrically around the tilt shaft 53, and the kneading ball support arm 52 attached around the eccentric rotor portion 63a is connected to the rod 66 on the hitting mechanism side. While being restrained, the eccentric rotor 63a is continuously swayed by the rotation of the eccentric rotor portion 63a. Along with this, the kneading balls 51 attached to one end of the kneading ball support arm 52 swings up and down, left and right and back and forth while drawing a continuous trajectory, thereby realizing a kneading as a treatment operation.

この揉み玉51の揉み動作に係る上下、左右及び前後の動きのうち、前後の動き成分、すなわち揉み玉51の被施療者側へ突出する動き及び逆に被施療者から離れる動きの成分については、傾動軸53を中心とした駆動機構部60の傾動に伴う揉み玉51の被施療者に対する進退移動と、その運動の向きをほぼ一致させることから、駆動機構部60の前記揉み機構による揉み動作と、傾動機構による駆動機構部60及び揉み玉51の傾動動作との複合により、揉み玉51における前後の動きの大きさ、すなわち揉み動作における揉み玉51の被施療者に対する突出量を任意に調整できる。そして、例えば、被施療者の身体に接した揉み玉51が前後の動きを伴わず押圧力を加えない状態で動く、いわゆる「さすり」のような動きを施療動作として実行する場合、揉み機構と傾動機構の複合動作により、揉み動作のうち揉み玉51の前後の動きの成分を打消してこれを実現でき、この際、傾動機構による傾動動作では揉み動作における揉み玉51の前後の動きの成分のみを打消せることで、揉み玉51の他の動き成分への影響を考慮せずに済むこととなり、制御を簡略に行えると共に、揉み玉が不自然な動きにならず被施療者に違和感を与えることもない。   Of the up / down, left / right, and front / back movements related to the kneading operation of the kneading balls 51, the front / rear movement components, that is, the movement of the kneading balls 51 that protrude toward the user and the movement of the movement away from the user Since the advancing / retreating movement of the kneading balls 51 with respect to the user with the tilting of the driving mechanism 60 around the tilting axis 53 is substantially matched with the direction of the movement, the kneading operation by the kneading mechanism of the driving mechanism 60 is performed. And the drive mechanism 60 by the tilting mechanism and the tilting motion of the kneading balls 51, the magnitude of the back and forth movement of the kneading balls 51, that is, the amount of protrusion of the kneading balls 51 with respect to the user in the kneading motion is arbitrarily adjusted it can. For example, in the case where the kneading balls 51 that are in contact with the body of the user move in a state where no pressing force is applied without moving back and forth, so-called “suri” movement is executed as a treatment operation, By the combined operation of the tilting mechanism, it is possible to cancel the component of the back and forth movement of the kneading ball 51 in the kneading operation, and at this time, the tilting operation by the tilting mechanism is a component of the back and forth movement of the kneading ball 51 in the kneading operation. By canceling only the effect, it is not necessary to consider the influence on the other motion components of the kneading balls 51, the control can be simplified, and the kneading balls do not move unnaturally, making the user feel uncomfortable. I don't give it.

また、叩き機構では、叩き軸65上の偏心ロータ部65aと揉み玉支持アーム52の他端部とをロッド66で連結することで、偏心ロータ部65aの回転によりロッド66が動いて、揉み玉支持アーム52を揉み軸部63上の偏心ロータ部63aを中心に揺動させる一種のクランク機構が構成されており、揉み玉支持アーム52の揺動でアーム一端部の揉み玉51も揺動して、施療動作としての叩きを実現する仕組みである。   Further, in the hitting mechanism, the eccentric rotor portion 65a on the hitting shaft 65 and the other end portion of the kneading ball support arm 52 are connected by the rod 66, whereby the rod 66 is moved by the rotation of the eccentric rotor portion 65a, and the kneading ball is moved. A kind of crank mechanism that swings the support arm 52 around the eccentric rotor portion 63a on the kneading shaft portion 63 is configured, and the kneading ball 51 at one end of the arm also rocks by the rocking of the kneading ball support arm 52. Thus, it is a mechanism that realizes tapping as a treatment operation.

この揉み玉51の叩き動作に係る揉み玉51の被施療者側へ突出する動き及び逆に被施療者から離れる動きについても、傾動軸53を中心とした駆動機構部60の傾動に伴う揉み玉51の被施療者に対する進退移動と、その運動の向きをほぼ一致させることから、駆動機構部60の前記叩き機構による叩き動作と、傾動機構による駆動機構部60及び揉み玉51の傾動動作との複合により、叩き動作における揉み玉51の被施療者に対する突出量、すなわち叩きのストロークを任意に調整できる。さらに、叩き動作に伴う揉み玉51の動きに合せて、傾動機構による傾動動作を適切なタイミングで実行することで、被施療者に対する揉み玉51の叩きの強弱調整も行える。   As for the movement of the kneading balls 51 that protrudes toward the user and the movement of the kneading balls 51 that move away from the user, the kneading balls that accompany the tilting of the drive mechanism 60 around the tilting shaft 53 are also used. 51, because the movement direction of the patient 51 substantially matches the direction of the movement, the hitting operation by the hitting mechanism of the drive mechanism unit 60 and the tilting operation of the drive mechanism unit 60 and the kneading balls 51 by the tilting mechanism. By the combination, the protruding amount of the kneading balls 51 with respect to the user in the hitting operation, that is, the hitting stroke can be arbitrarily adjusted. Furthermore, the strength of the hitting of the kneading balls 51 with respect to the user can be adjusted by executing the tilting operation by the tilting mechanism at an appropriate timing in accordance with the movement of the kneading balls 51 accompanying the hitting operation.

前記ベース部54は、傾動軸53を軸支することで駆動機構部60を傾動可能に支持するものであり、この他、傾動軸53を減速機構を介して回転駆動する昇降モータ57と、駆動機構部60を傾動させて揉み玉51を被施療者に対し進退させ、施療の強さを調整する進退モータ58とを備える構成である。   The base portion 54 supports the drive mechanism portion 60 so as to be tiltable by supporting the tilt shaft 53. In addition, the base portion 54 is driven by a lift motor 57 that rotationally drives the tilt shaft 53 via a speed reduction mechanism. The mechanism portion 60 is tilted to move the kneading balls 51 forward and backward with respect to the user, and includes an advance / retreat motor 58 that adjusts the strength of treatment.

進退モータ58は、駆動機構部60におけるハウジング61側部の部分歯車67と噛合させたピニオンギヤ58aに減速機構を介して回転駆動力を与え、ピニオンギヤ58aを回転させ、部分歯車67を傾動軸53を中心として移動させることで、駆動機構部60の傾動軸53を中心とした傾動を実現するものである。この進退モータ58は、あらかじめ施療開始前に被施療者の身体(例えば、肩から腰までのカーブ)を調査して得られた情報に基づく制御部40の制御により、その駆動状態を変化させて駆動機構部60を傾動させ、揉み玉51を進退させて揉み玉51の被施療者に対する突出量を調整し、被施療者ごとに最適な施療を提供できるようにしている。   The advancing / retracting motor 58 applies a rotational driving force to the pinion gear 58a meshed with the partial gear 67 on the side of the housing 61 in the drive mechanism 60 via the speed reduction mechanism, rotates the pinion gear 58a, and causes the partial gear 67 to move the tilt shaft 53. By moving it as the center, the tilt about the tilt shaft 53 of the drive mechanism 60 is realized. The advance / retreat motor 58 changes its drive state under the control of the control unit 40 based on information obtained by examining the body of the user (for example, a curve from the shoulder to the waist) before starting treatment. The drive mechanism 60 is tilted to move the kneading balls 51 forward and backward to adjust the amount of protrusion of the kneading balls 51 with respect to the user, so that optimal treatment can be provided for each user.

なお、ハウジング61側部の部分歯車67は、可能な限りそのピッチ円半径を小さく形成され、且つ、駆動機構部60と一体に傾動する揉み玉51に対し、背もたれ部13にもたれた場合の被施療者の背面位置を越えて突出可能となる傾動範囲を与えることのできる、十分な周方向長さとして形成されて、中心の傾動軸53に近い位置に配設される。また、この部分歯車67と噛合するピニオンギヤ58aは、ベース部54側の進退モータ58及び減速機構から部分歯車67と噛合可能な位置まで突出した片持ち支持の状態で配設されており、このピニオンギヤ58aをはじめとする部分歯車67の駆動機構とハウジング61との接触はない。   The partial gear 67 on the side of the housing 61 is formed with a pitch circle radius as small as possible, and the covered gear 51 when tilted integrally with the drive mechanism 60 is leaned against the backrest 13. It is formed as a sufficient length in the circumferential direction that can provide a tilting range that can protrude beyond the back surface position of the user, and is disposed at a position near the tilting shaft 53 at the center. The pinion gear 58a meshing with the partial gear 67 is disposed in a cantilevered state protruding from the advance / retreat motor 58 and the speed reduction mechanism on the base portion 54 side to a position where it can mesh with the partial gear 67. There is no contact between the drive mechanism of the partial gear 67 including 58 a and the housing 61.

こうして部分歯車67及びピニオンギヤ58aを用いて、駆動機構部60の傾動機構をコンパクトに構成しているが、これは、揉み玉51を取付けた揉み玉支持アーム52を揉み軸部63で支持すると共に、揉み軸部63を傾動軸53上に取付けて、揉み軸部63の中心位置を駆動機構部60の傾動中心である傾動軸53と一致させ、外部から揉み玉51に加わる力が揉み玉支持アーム52及び揉み軸部63を介して傾動軸53にそのまま伝わるようにしていることによるもので、駆動機構部60の傾動機構に不要な力が加わらず、部分歯車67及びピニオンギヤ58aを強度の高い構造とする必要が無く、特に、ピニオンギヤ58aを片持ち支持としても問題なく動作させられることで、簡略な傾動機構が実現している。   Thus, the partial gear 67 and the pinion gear 58a are used to make the tilting mechanism of the drive mechanism 60 compact. This is because the kneading ball support arm 52 to which the kneading balls 51 are attached is supported by the kneading shaft 63. The kneading shaft portion 63 is mounted on the tilting shaft 53 so that the center position of the kneading shaft portion 63 coincides with the tilting shaft 53 that is the tilting center of the drive mechanism 60, and the force applied to the kneading balls 51 from the outside is supported by the kneading balls. This is because it is transmitted as it is to the tilting shaft 53 via the arm 52 and the squeezing shaft portion 63, and unnecessary force is not applied to the tilting mechanism of the drive mechanism portion 60, and the partial gear 67 and the pinion gear 58a have high strength. There is no need for a structure, and in particular, a simple tilting mechanism is realized by operating the pinion gear 58a as a cantilever without any problem.

また、簡略で且つ駆動機構部60との物理的干渉をほとんど考慮せずに済む機構となっている部分歯車67及びピニオンギヤ58aを、駆動機構部60横の傾動軸53に近い部位に配置できることで、駆動機構部の傾動機構を傾動軸に対し駆動機構部より外周側となる位置に配置していた場合と比べて、駆動機構部60全体の小型化が図れると共に、容易に部分歯車67の周方向長さを確保して、揉み玉の突出量を大きくできる構造が無理なく得られる。こうした揉み玉51の突出量を大きくできる構造では、突出状態とされた揉み玉51が被施療者に対し背面側からだけでなく上方や下方から接近することができ、被施療者の身体各位置の検出や揉み玉51によるマッサージ動作を効率的に実行でき、特にマッサージにおいてはそのバリエーションを増大させて、変化に富んだマッサージ効果を与えられる。   In addition, the partial gear 67 and the pinion gear 58a, which are simple and require little consideration of physical interference with the drive mechanism 60, can be disposed at a location near the tilt shaft 53 beside the drive mechanism 60. Compared with the case where the tilting mechanism of the drive mechanism unit is arranged at a position closer to the outer peripheral side than the drive mechanism unit with respect to the tilting shaft, the entire drive mechanism unit 60 can be downsized and the peripheral gear 67 can be easily rotated. A structure that can secure the length in the direction and increase the amount of protrusion of the kneading balls can be obtained without difficulty. In the structure in which the amount of protrusion of the kneading balls 51 can be increased, the kneading balls 51 in a protruding state can approach the user not only from the back side but also from the upper side and the lower side. Detection and massage operation by the kneading balls 51 can be efficiently executed. In particular, in the massage, the variation can be increased and a massage effect rich in change can be given.

前記回転体55は、一部を円筒面状、他部を歯車状として形成され、ベース部54の側端部下寄りで回転の中心軸となる傾動軸53の軸端に固定支持されて、それぞれ傾動軸53と共にベース部54に対し回動可能として配設され、歯車状部分をピニオンギヤ部55aとしてガイドフレーム20のラック21と噛合させる構成である。この回転体55のピニオンギヤ部55aと、十分な幅として形成された樹脂製のラック21とが広い接触面積を確保しつつ噛合することで、回転体55が回転してピニオンギヤ部55aとラック21との噛合状態を変化させても異音が生じにくく、また接触に伴う摩擦も小さく抑えられる。   The rotating body 55 is partly formed in a cylindrical shape and the other part is formed in a gear shape, and is fixedly supported on the shaft end of the tilting shaft 53 that is the central axis of rotation near the side end portion of the base portion 54, respectively. It is arranged so as to be rotatable with respect to the base portion 54 together with the tilting shaft 53, and the gear-like portion is engaged with the rack 21 of the guide frame 20 as a pinion gear portion 55a. The pinion gear portion 55a of the rotating body 55 and the resin rack 21 formed with a sufficient width engage with each other while ensuring a wide contact area, whereby the rotating body 55 rotates and the pinion gear portion 55a and the rack 21 are engaged with each other. Even if the meshing state is changed, abnormal noise is hardly generated, and friction caused by contact can be suppressed to be small.

この回転体55に加え、ベース部54の側端部上側にはガイドローラ59がそれぞれ回動可能に取付けられており、これらのガイドローラ59がガイドフレーム20に挿嵌されて回転体55と共にガイドフレーム20長手方向以外の動きを拘束されることで、ベース部54が一対のガイドフレーム20に背もたれ部上下方向に移動可能で且つ他方向への動きを拘束されて支持されることとなる。   In addition to the rotating body 55, guide rollers 59 are rotatably attached to the upper side end portions of the base portion 54. These guide rollers 59 are inserted into the guide frame 20 and guided together with the rotating body 55. By restraining the movement in the direction other than the longitudinal direction of the frame 20, the base part 54 can be moved in the vertical direction of the backrest part by the pair of guide frames 20, and supported in the other direction by restraining the movement in the other direction.

そして、回転体55が、昇降モータ57による傾動軸53の駆動に伴って回転することで、ラック21との噛合位置を変えてガイドフレーム20を走行する状態となり、同時にベース部54をはじめとするメカユニット50全体をガイドフレーム20に沿って背もたれ部13の上下に移動させる仕組みとなっており、これにより揉み玉51による被施療部位を上下に変えることができる。このメカユニット50の上下移動に際し、昇降モータ57は、制御部40から出力される制御信号を受けて作動しており、揉み玉51を背もたれ部13でこの揉み玉51による各種マッサージを被施療者に対し提供するのに最適な箇所にそれぞれ位置させることとなる。   The rotating body 55 rotates as the tilting shaft 53 is driven by the elevating motor 57, thereby changing the meshing position with the rack 21 and traveling the guide frame 20, and simultaneously starting with the base portion 54. The entire mechanical unit 50 is moved up and down the backrest 13 along the guide frame 20, whereby the treatment site by the kneading balls 51 can be changed up and down. When the mechanical unit 50 moves up and down, the elevating motor 57 is operated in response to a control signal output from the control unit 40, and the massager 51 receives various massages from the massager 51 on the backrest 13. It will be located at the most suitable place to provide for.

さらに、ベース部54側端部には複数のローラ56も配設されており、これらローラ56が、回転体55との間隔を維持したまま、回転体55のピニオンギヤ部55aがラック21と噛合する状態で、ガイドフレーム20におけるラック21のある面の裏側にあたる外周面に転がり接触して、回転体55とローラ56がガイドフレーム20の一部を挟んだ状態を保ちながら、ガイドフレーム20に対し上下に移動することで、回転体55とラック21とがこのローラ56で離隔を阻止されて噛合状態を確実に維持し、回転する回転体55がガイドフレーム20に対し確実に上下動できることとなり、メカユニット50全体を正確に上下動させられ、施療子である揉み玉51を正確に所望の上下方向位置に調整できる。また、このローラ56の存在でガイドフレーム20の形状精度に関わりなく回転体55をラック21寄りに位置させてピニオンギヤ部55aとラック21の噛合状態を維持でき、ガイドフレームを高精度に形成し且つ外力に対しその形状を厳密に維持できる高い剛性を確保する必要がなく、ガイドフレームの構造を簡略化、軽量化することもできる。   Further, a plurality of rollers 56 are also arranged at the end of the base portion 54, and the pinion gear portion 55 a of the rotating body 55 meshes with the rack 21 while these rollers 56 maintain a distance from the rotating body 55. In this state, the rolling body 55 and the roller 56 are vertically in contact with the guide frame 20 while maintaining a state in which the rotating body 55 and the roller 56 sandwich a part of the guide frame 20 while being in contact with the outer peripheral surface of the guide frame 20 on the back side of the surface with the rack 21 , The rotating body 55 and the rack 21 are prevented from being separated from each other by the roller 56 and the meshing state is reliably maintained, and the rotating rotating body 55 can move up and down reliably with respect to the guide frame 20. The entire unit 50 can be accurately moved up and down, and the massaging balls 51 as the treatment element can be accurately adjusted to a desired vertical position. Further, the presence of the roller 56 allows the rotating body 55 to be positioned closer to the rack 21 regardless of the shape accuracy of the guide frame 20 to maintain the meshed state of the pinion gear portion 55a and the rack 21, thereby forming the guide frame with high accuracy and It is not necessary to secure high rigidity capable of maintaining the shape strictly against external force, and the structure of the guide frame can be simplified and reduced in weight.

前記肘掛部14は、座部12の両側に位置して基台部11と一体に連結し、背もたれ部13がリクライニング角度を変化させたり、座部12が傾動しても、被施療者の前腕を安定的に支持するよう形成される構成である。この肘掛部14にも、前記エアポンプ70による空気の給排で動作するエアセルを配設して、被施療者の前腕部に対しマッサージを行える構成としてかまわない。   The armrest part 14 is located on both sides of the seat part 12 and is integrally connected to the base part 11. Even if the backrest part 13 changes the reclining angle or the seat part 12 tilts, the forearm of the user It is the structure formed so that it may be supported stably. The armrest portion 14 may also be configured such that an air cell that operates by supplying and discharging air by the air pump 70 can be provided to massage the forearm portion of the user.

前記脚支持部15は、座部12の前側に位置し、座部12前端付近を中心として傾動可能に配設され、内蔵のアクチュエータ(図示を省略)により傾斜角度を調整されるものである。この脚支持部15にも、前記エアポンプ70による空気の給排で動作する脚用エアセルや、上下に移動しつつ脚を押圧するローラ等の施療機構を配設するようにしてかまわない。   The leg support portion 15 is positioned on the front side of the seat portion 12 and is disposed so as to be tiltable about the vicinity of the front end of the seat portion 12, and the tilt angle is adjusted by a built-in actuator (not shown). A treatment mechanism such as a leg air cell that operates by supplying and discharging air by the air pump 70 and a roller that presses the leg while moving up and down may also be provided in the leg support portion 15.

前記リモコン30は、マッサージ機に対する各種操作入力を受付ける多数のスイッチや表示部を備え、マッサージ機1の側部におけるスタンド16に着脱自在に設置され、マッサージに係る操作入力を制御部40に送信するものである。なお、リモコン30のスイッチや表示部の位置を被施療者にとって最適位置とするために、スタンド16の位置は調整可能となっている。   The remote controller 30 includes a large number of switches and display units for receiving various operation inputs to the massage machine, is detachably installed on the stand 16 on the side of the massage machine 1, and transmits operation inputs related to massage to the control unit 40. Is. Note that the position of the stand 16 can be adjusted so that the position of the switch and the display unit of the remote controller 30 is the optimum position for the user.

前記制御部40は、揉み玉51をはじめとするメカユニット50を用いて被施療者の身体各部位置検出を実行し、その検出結果に基づいて、施療機構やマッサージ機の他の各可動部分を被施療者に対応した状態に調整すると共に、施療機構や他の各可動部分に対し、リモコン操作やあらかじめ記録設定されたマッサージ内容、また前記検出結果の情報に基づいて、適切なマッサージの実行のための動作制御を行うものである。   The control unit 40 detects the position of each part of the body of the user using the mechanical unit 50 including the kneading balls 51, and based on the detection result, the other movable parts of the treatment mechanism and the massage machine are detected. In addition to adjusting to a state corresponding to the user, appropriate massage is performed based on the remote control operation, the massage contents recorded and set in advance, and the detection result information for the treatment mechanism and other movable parts. Operation control is performed.

この制御部40は、そのハードウェア構成として、CPUやメモリ、入出力インターフェース等を備えるコンピュータとなっており、メモリ等に格納されるプログラムにより、コンピュータを制御部40として動作させる仕組みである。この制御部40をなすコンピュータは、CPUやメモリ、ROM等を一体的に形成されたマイクロコンピュータとしてもかまわない。   The control unit 40 is a computer including a CPU, a memory, an input / output interface, and the like as its hardware configuration, and is a mechanism that causes the computer to operate as the control unit 40 by a program stored in the memory or the like. The computer constituting the control unit 40 may be a microcomputer in which a CPU, a memory, a ROM, and the like are integrally formed.

この制御部40をなすコンピュータのユニットは、座部12直下等のマッサージ機1内部の所定のスペースに配設され、リモコン30と通信可能な状態とされると共に、メカユニット50や、背もたれ部13や脚支持部15の各アクチュエータ、エアポンプ70とそれぞれ電気的に接続され、被施療者の身体各部位置検出の際にはあらかじめ設定された位置検出用プログラムに基づく制御信号出力により、また、マッサージ実行の際には設定されたマッサージのデータに基づく制御信号出力により、これらの駆動機構を動作させる。さらに制御部40は、メカユニット50や各アクチュエータの変位量を出力するエンコーダ等の信号出力手段とも電気的に接続されており、メカユニット50の状態や、背もたれ部13及び脚支持部15の傾斜等の状態を把握しつつこれらの動作制御を行うこととなる。   The computer unit constituting the control unit 40 is disposed in a predetermined space inside the massage machine 1 such as immediately below the seat 12 and is in a state where it can communicate with the remote controller 30, and the mechanical unit 50 and the backrest unit 13. And each actuator of the leg support 15 and the air pump 70 are electrically connected to each other, and when detecting the position of each part of the body of the user, a control signal is output based on a preset position detection program, and a massage is executed. In this case, these drive mechanisms are operated by a control signal output based on the set massage data. Further, the control unit 40 is also electrically connected to a signal output means such as an encoder that outputs the displacement amount of the mechanical unit 50 and each actuator, and the state of the mechanical unit 50 and the inclination of the backrest 13 and the leg support 15 are also shown. These operation controls are performed while grasping the state of the above.

制御部40は、マッサージに先立つ被施療者の身体各部位置検出として、メカユニット50を制御して、メカユニット50を背もたれ部13における初期位置からガイドフレーム20に沿って移動させつつ駆動機構部60を傾動させて、揉み玉51を被施療者に沿って動かす過程で、背もたれ部13にもたれた被施療者側からの揉み玉51に対する圧力の変化や揉み玉51の傾き変化等を順次取得し、この情報に基づいて、被施療者の肩位置、背骨のライン、腰位置を検出する仕組みである。特に、肩位置を検出する場合、制御部40は、揉み玉51をいったん肩より上方に位置させ、さらに、駆動機構部60を傾動させ、揉み玉51の被施療者側への突出量を背もたれ部13にもたれた被施療者の背面位置を越える大きさとした上で、揉み玉51を被施療者の肩より上方から駆動機構部60ごと下降させ(図17(A)参照)、揉み玉51が肩上側に到達した状態(図17(B)参照)を検出することで、被施療者の肩位置を検出、認定することとなる。   The control unit 40 controls the mechanical unit 50 to detect the position of each part of the body of the user prior to the massage, and moves the mechanical unit 50 along the guide frame 20 from the initial position of the backrest unit 13. In the process of moving the kneading balls 51 along the user, the change in the pressure on the kneading balls 51 from the user leaning against the backrest 13 and the change in the inclination of the kneading balls 51 are sequentially acquired. Based on this information, the shoulder position, spine line, and waist position of the user are detected. In particular, when detecting the shoulder position, the control unit 40 temporarily positions the kneading balls 51 above the shoulder, further tilts the drive mechanism 60, and puts the amount of protrusion of the kneading balls 51 toward the user back on the back. The size of the kneading ball 51 is lowered from above the shoulder of the user with the drive mechanism 60 (see FIG. 17A), and the size of the kneading ball 51 is lowered from the shoulder of the user. By detecting the state (see FIG. 17B) that has reached the upper shoulder side, the shoulder position of the user is detected and authorized.

一方、マッサージの場合においても、揉み玉51が背もたれ部13にもたれた被施療者の背面位置を越えて突出可能な機構を有していることで、制御部40はこれを利用したマッサージを実行させることもでき、例えば、制御部40は揉み玉51をいったん被施療者の肩より上方に位置させた後、駆動機構部60を傾動させ、揉み玉51の被施療者側への突出量を背もたれ部13にもたれた被施療者の背面位置を越える大きさとした上で、揉み玉51を被施療者の肩より上方から駆動機構部60ごと下降させ、揉み玉51を肩上側に到達させて、揉み玉51の肩上側部分に対するマッサージ動作を実行させることができる(図13(A)参照)。   On the other hand, even in the case of massage, the control unit 40 performs a massage using this by having a mechanism in which the kneading balls 51 can protrude beyond the back position of the user leaning on the backrest 13. For example, after the kneading balls 51 are once positioned above the shoulders of the user, the control unit 40 tilts the drive mechanism 60 so that the amount of the kneading balls 51 protruding toward the user is increased. The size of the massaging ball 51 is lowered from above the shoulder of the user together with the drive mechanism unit 60 so that the massaging ball 51 reaches the shoulder upper side after the size of the back surface of the user leaning on the backrest portion 13 is exceeded. The massage operation for the upper shoulder portion of the kneading balls 51 can be executed (see FIG. 13A).

また逆に、制御部40は揉み玉51をいったん背もたれ部13最下部の被施療者の腰より下側に位置させた後、駆動機構部60を傾動させ、揉み玉51の被施療者側への突出量を背もたれ部13にもたれた被施療者の背面位置を越える大きさとした上で、揉み玉51を被施療者の腰部より下方から駆動機構部60ごと上昇させ、揉み玉51を腰部下側に到達させて、揉み玉51の腰部下側部分に対するマッサージ動作を実行させることもできる(図13(B)参照)。   Conversely, the control unit 40 once places the massaging balls 51 below the waist of the user at the bottom of the backrest 13 and then tilts the drive mechanism 60 to move the massaging balls 51 toward the user. The amount of protrusion is set to be larger than the back position of the user leaning against the backrest 13, and the kneading balls 51 are raised together with the drive mechanism 60 from below the waist of the user, so that the kneading balls 51 are moved below the waist. It can also be made to reach the side, and the massage operation | movement with respect to the waist lower part of the kneading ball 51 can also be performed (refer FIG. 13 (B)).

次に、本実施形態に係るマッサージ機における被施療者の肩位置検出動作及び突出状態の揉み玉によるマッサージ動作について説明する。はじめに、被施療者の肩位置検出動作について、図14のフローチャートを用いて説明する。前提として、マッサージ機1に被施療者が着座して背中を背もたれ部13にもたれさせた状態で、マッサージ機1の主電源が入とされ、マッサージ機1が起動したものとする。   Next, the shoulder position detection operation of the user and the massage operation using the protruding kneading balls in the massage machine according to the present embodiment will be described. First, the shoulder position detection operation of the user will be described using the flowchart of FIG. As a premise, it is assumed that the main power of the massage machine 1 is turned on and the massage machine 1 is started in a state where the user is seated on the massage machine 1 and the back is leaned against the backrest 13.

まず、制御部40は、背もたれ部13下方の初期位置にあるメカユニット50において、進退モータ58を作動させ、ピニオンギヤ58aを駆動して部分歯車67を動かし、揉み玉51と駆動制御部60を傾動させて、揉み玉51を被施療者側に向わせる(ステップS001)。また、制御部40は昇降モータ57も作動させ、回転体55を回転させてガイドフレーム20に対しメカユニット50全体を上に動かす(ステップS002)。こうして、揉み玉51を被施療者の背中に押付けながら、揉み玉51を背もたれ部13の下方から上昇させる状態が得られる(図15参照)。この時、揉み玉51が被施療者の背中で突出を阻止され、それ以上前方へ進めないので、駆動機構部60も傾動できず、作動中の進退モータ58には大きな負荷がかかった状態となっている。   First, in the mechanical unit 50 in the initial position below the backrest 13, the control unit 40 operates the advance / retreat motor 58, drives the pinion gear 58 a to move the partial gear 67, and tilts the kneading balls 51 and the drive control unit 60. Then, the kneading balls 51 are directed toward the user (step S001). The control unit 40 also operates the lifting motor 57 to rotate the rotating body 55 and move the entire mechanical unit 50 upward with respect to the guide frame 20 (step S002). In this way, a state in which the kneading balls 51 are raised from below the backrest 13 while the kneading balls 51 are pressed against the back of the user is obtained (see FIG. 15). At this time, the kneading balls 51 are prevented from projecting on the back of the user and cannot move forward any further, so that the drive mechanism 60 cannot tilt, and the advancing / retracting motor 58 in operation is under a heavy load. It has become.

揉み玉51が上昇を続けて、肩を越えた位置に達すると(図16(A)参照)、揉み玉51が被施療者の背中を押さない状態となり、揉み玉51が被施療者の背面位置を越えて前方へ進めることで、駆動機構部60が傾動を開始し、進退モータ58の負荷が急減することとなる。制御部40はこの進退モータ58の負荷を監視して(ステップS003)、負荷が急減する状態に達したか否かを判定する(ステップS004)。負荷が急減する状態に達したと判定したら、制御部40はその時点の揉み玉51の位置を肩の仮位置と認定し、同時に進退モータ58を停止させ、揉み玉51と駆動制御部60が傾動しないようにして、揉み玉51がそれ以上突出しないようにする(ステップS005)。一方、前記ステップS004で負荷が急減する状態に達していない場合は、再びステップS003に戻って、進退モータ58の負荷の監視を繰返す。   When the kneading balls 51 continue to rise and reach a position beyond the shoulder (see FIG. 16A), the kneading balls 51 do not press the back of the user, and the kneading balls 51 are in the back of the user. By proceeding forward beyond the position, the drive mechanism 60 starts tilting, and the load on the advance / retreat motor 58 is suddenly reduced. The control unit 40 monitors the load of the advance / retreat motor 58 (step S003), and determines whether or not a state where the load suddenly decreases is reached (step S004). If it is determined that the load suddenly decreases, the control unit 40 recognizes the position of the kneading ball 51 at that time as the temporary position of the shoulder, and simultaneously stops the advancing / retreating motor 58 so that the kneading ball 51 and the drive control unit 60 The kneading balls 51 are prevented from tilting so that the kneading balls 51 do not protrude any more (step S005). On the other hand, if the load has not reached the state of sudden decrease in step S004, the process returns to step S003 again and the monitoring of the load of the advance / retreat motor 58 is repeated.

肩の仮位置認定後、制御部40はさらに昇降モータ57の作動を継続させ、メカユニット50を上に移動させる一方(図16(B)参照)、進退モータ58は停止したままとして、揉み玉51を進退させない状態で所定距離、例えば10cm程度上昇させる(ステップS006)。上昇後、制御部40は、昇降モータ57をいったん停止させると共に、進退モータ58を作動させて揉み玉51と駆動制御部60を再び傾動させ、揉み玉51を背もたれ部13前方側へ最大限突出させる(ステップS007)。   After the temporary position of the shoulder is recognized, the control unit 40 continues the operation of the lifting motor 57 and moves the mechanical unit 50 upward (see FIG. 16B), while the advance / retreat motor 58 remains stopped, and the kneading balls A predetermined distance, for example, about 10 cm, is raised in a state where 51 is not advanced or retracted (step S006). After the ascent, the control unit 40 temporarily stops the elevating motor 57 and operates the advance / retreat motor 58 to tilt the kneading balls 51 and the drive control unit 60 again so that the kneading balls 51 protrude to the front side of the backrest 13 to the maximum. (Step S007).

揉み玉51を突出させたら(図17(A)参照)、制御部40は進退モータ58を停止させる一方、昇降モータ57を作動させ、回転体55を前記上移動の場合とは逆方向に回転させて、メカユニット50と共に揉み玉51を下降させていく(ステップS008)。揉み玉51が肩上側に近接すると(図17(B)参照)、揉み玉51の下降速度が低下するのに伴い、昇降モータ57の負荷が急増するため、制御部40はこの昇降モータ57の負荷を監視して(ステップS009)、負荷が急増する状態に達したか否かを判定する(ステップS010)。負荷が急増する状態に達したと判定したら、制御部40は、その時点の揉み玉位置を取得し、この揉み玉位置を真の肩位置として認定する(ステップS011)。一方、前記ステップS010で負荷が急増する状態に達していない場合は、再びステップS009に戻って、昇降モータ57の負荷の監視を繰返す。   When the kneading balls 51 are protruded (see FIG. 17A), the control unit 40 stops the advance / retreat motor 58 and operates the elevating motor 57 to rotate the rotating body 55 in the opposite direction to the upward movement. Then, the kneading balls 51 are lowered together with the mechanical unit 50 (step S008). When the kneading balls 51 come close to the shoulder upper side (see FIG. 17B), the load on the elevating motor 57 increases rapidly as the descent speed of the kneading balls 51 decreases. The load is monitored (step S009), and it is determined whether or not a state in which the load increases rapidly (step S010). If it determines with having reached the state where load increases rapidly, the control part 40 will acquire the kneading ball position at that time, and will recognize this kneading ball position as a true shoulder position (step S011). On the other hand, if the load has not reached the state of sudden increase in step S010, the process returns to step S009 again, and the monitoring of the load on the lifting motor 57 is repeated.

真の肩位置を認定したら、制御部40は昇降モータ57を一旦停止させた後逆転させ、メカユニット50と共に揉み玉51を上昇させて、揉み玉51を肩上側から離隔させる(ステップS012)と共に、進退モータ58を作動させて揉み玉51と駆動制御部60を傾動させ、揉み玉51を被施療者から離れる向きに移動させ、メカユニットの上下動に際し揉み玉が背もたれ部13にもたれた被施療者の背面と物理的に干渉しない位置まで後退させる(ステップS013)。この後、制御部40が、昇降モータ57を一旦停止させた後再び作動させ、メカユニット50を下に移動させて初期位置まで戻す(ステップS014)と、一連の肩検出動作が完了となる。   When the true shoulder position is identified, the control unit 40 temporarily stops the elevating motor 57 and then reverses it, raises the kneading balls 51 together with the mechanical unit 50, and separates the kneading balls 51 from the upper shoulder (step S012). Then, the kneading balls 51 and the drive control unit 60 are tilted by operating the advancing / retreating motor 58 to move the kneading balls 51 away from the user, and the kneading balls are leaned against the backrest 13 when the mechanical unit is moved up and down. Retreat to a position that does not physically interfere with the back of the user (step S013). Thereafter, when the control unit 40 temporarily stops the lifting motor 57 and then operates it again to move the mechanical unit 50 downward and return it to the initial position (step S014), a series of shoulder detection operations are completed.

こうして正確な肩位置の情報が得られた後、必要に応じて、体重測定や腰位置などの身体他部分の位置検出などのマッサージ開始前の準備動作が制御部40により実行された後、被施療者によりマッサージコース等の動作状態指示が入力され、制御部40が入力を受けて、各施療機構によるマッサージ動作が開始することとなる。揉み玉51によるマッサージの場合、設定されたマッサージの内容に応じて、制御部40は、昇降モータ57を作動させて各回転体55を回転させ、ガイドフレーム20に対しメカユニット50全体を上下に移動させ、揉み玉51の上下位置を調整すると共に、進退モータ58を作動させて揉み玉51と駆動制御部60を傾動させ、揉み玉51の被施療者側への突出量を調整して、揉み玉51をマッサージの対象箇所に位置させる。この後、又はこうした揉み玉51の移動と並行して、制御部40は、マッサージの種類に応じて、揉みモータ62及び/又は叩きモータ64を作動させ、揉み玉51に設定された揉みや叩き等のマッサージに対応した動きを行わせることとなる。   After the accurate shoulder position information is obtained in this way, the preparatory operation before the start of massage, such as weight measurement and position detection of other body parts such as the waist position, is performed by the control unit 40 as necessary. An operation state instruction such as a massage course is input by the user, and the control unit 40 receives the input, and a massage operation by each treatment mechanism is started. In the case of massage with the kneading balls 51, the control unit 40 operates the lifting motor 57 to rotate each rotating body 55 according to the set massage content, and the entire mechanical unit 50 is moved up and down with respect to the guide frame 20. Move and adjust the vertical position of the kneading balls 51, actuate the advance / retreat motor 58 to tilt the kneading balls 51 and the drive control unit 60, and adjust the amount of protrusion of the kneading balls 51 to the user, The massaging balls 51 are positioned at the massage target location. Thereafter, or in parallel with the movement of the kneading balls 51, the control unit 40 operates the kneading motor 62 and / or the tapping motor 64 according to the type of massage, and the kneading and tapping set in the kneading balls 51. The movement corresponding to the massage is performed.

このようにマッサージを行う中、揉み玉51は被施療者側から相対的に押される状態となって、揉み玉51には押圧力が加わるが、揉み玉51を取付けた揉み玉支持アーム52を揉み軸部63で支持すると共に、この揉み軸部63を傾動軸53上にその中心を一致させて取付け、揉み玉51に加わる力が揉み玉支持アーム52及び揉み軸部63を介して傾動軸53にそのまま伝わるようにしていることで、傾動軸53以外の、駆動機構部60の傾動機構をなすピニオンギヤ58aに駆動機構部60を介して強い力が加わることはなく、ピニオンギヤ58aで部分歯車67を無理なく動作させて、駆動機構部60のスムーズな傾動を実現できる。   During massage, the kneading balls 51 are relatively pressed from the user side, and a pressing force is applied to the kneading balls 51, but the kneading balls supporting arm 52 to which the kneading balls 51 are attached is provided. The kneading shaft portion 63 is supported by the kneading shaft portion 63 and mounted on the tilting shaft 53 so that the center thereof coincides, and the force applied to the kneading ball 51 is tilted through the kneading ball support arm 52 and the kneading shaft portion 63. 53, the pinion gear 58a that forms the tilt mechanism of the drive mechanism 60 other than the tilt shaft 53 is not applied with a strong force via the drive mechanism 60, and the partial gear 67 is generated by the pinion gear 58a. Thus, the drive mechanism 60 can be smoothly tilted.

続いて、被施療者が背もたれ部13にもたれた場合の被施療者の背面位置を揉み玉51が大きく越えて突出した状態での、揉み玉による被施療者に対する上方や下方からのマッサージ動作について説明する。   Subsequently, the massage operation from above or below the user with the kneading balls with the kneading balls 51 projecting far beyond the back position of the user when the user leans against the backrest 13 explain.

まず、揉み玉51で被施療者の肩に対し上方からマッサージを行う場合、制御部40は、揉み玉51が被施療者の肩位置より上方に存在するように、必要に応じて、昇降モータ57を作動させ、回転体55を回転させてガイドフレーム20に対しメカユニット50全体を上に移動させ、揉み玉51を上昇させる(図16(B)参照)。そして、揉み玉51が被施療者の肩位置より上方に存在する状態で、制御部40は、進退モータ58を作動させて揉み玉51と駆動制御部60を傾動させ、揉み玉51の被施療者側への突出量を背もたれ部13にもたれた被施療者の背面位置より大きくする(図17(A)参照)。   First, when massaging the shoulder of the user with the kneading balls 51 from above, the control unit 40 moves the lifting motor as necessary so that the kneading balls 51 are present above the shoulder position of the user. 57 is operated to rotate the rotating body 55 to move the entire mechanical unit 50 upward with respect to the guide frame 20 and raise the kneading balls 51 (see FIG. 16B). Then, in a state where the kneading balls 51 are present above the shoulder position of the user, the control unit 40 operates the advance / retreat motor 58 to tilt the kneading balls 51 and the drive control unit 60 to treat the kneading balls 51. The amount of protrusion to the person side is made larger than the back position of the user who leans against the backrest 13 (see FIG. 17A).

さらに制御部40は、進退モータ58を停止させる一方、昇降モータ57を作動させて、メカユニット50と共に揉み玉51を下降させ、揉み玉51を被施療者の肩より上の位置から、あらかじめ検出した肩位置に到達させる(図17(B)参照)。この状態で、制御部40は駆動機構部60の揉みモータ62及び/又は叩きモータ64を作動させて、揉み玉51の肩上側部分に対する揉み及び/又は叩きのマッサージ動作を実行する(図13(A)参照)。こうして肩に対する揉み玉51での揉みや叩き等のマッサージを肩上側から行うことで、背面側からのマッサージとは異なる新たなマッサージ効果を付与することができ、施療効果を高められることとなる。   Further, the control unit 40 stops the advance / retreat motor 58 and operates the elevating motor 57 to lower the kneading balls 51 together with the mechanical unit 50 so that the kneading balls 51 are detected in advance from a position above the shoulder of the user. The shoulder position is reached (see FIG. 17B). In this state, the control unit 40 operates the kneading motor 62 and / or the tapping motor 64 of the drive mechanism unit 60 to execute a massage operation of kneading and / or tapping on the shoulder upper portion of the kneading balls 51 (FIG. 13 ( A)). Thus, by performing massage such as massage or hitting with the kneading balls 51 on the shoulder from the upper side of the shoulder, a new massage effect different from the massage from the back side can be provided, and the treatment effect can be enhanced.

また、揉み玉51で被施療者の腰に対し下方からマッサージを行う場合、制御部40は、揉み玉51が被施療者の腰位置より下方に存在するように、必要に応じて、昇降モータ57を作動させ、回転体55を回転させてガイドフレーム20に対しメカユニット50全体を下に移動させ、揉み玉51を下降させる。そして、揉み玉51が被施療者の腰位置より下方に存在する状態で、制御部40は、進退モータ58を作動させて揉み玉51と駆動機構部60を傾動させ、揉み玉51の被施療者側への突出量を背もたれ部13にもたれた被施療者の背面位置より大きくする。   In addition, when massaging the user's waist with the massage balls 51 from below, the control unit 40 moves the lifting motor as necessary so that the massage balls 51 exist below the waist position of the users. 57 is operated to rotate the rotating body 55 to move the entire mechanical unit 50 downward with respect to the guide frame 20 and lower the kneading balls 51. In a state where the kneading balls 51 are present below the waist position of the user, the control unit 40 operates the advancing / retreating motor 58 to tilt the kneading balls 51 and the drive mechanism 60 to treat the kneading balls 51. The amount of protrusion to the person side is made larger than the back position of the user who leans against the backrest 13.

さらに制御部40は、進退モータ58を停止させる一方、昇降モータ57を作動させて、メカユニット50と共に揉み玉51を上昇させ、揉み玉51を腰直下に到達させる。この状態で、制御部40は駆動機構部60の揉みモータ62及び/又は叩きモータ64を作動させて、揉み玉51の腰下側部分に対する揉み及び/又は叩きのマッサージ動作を実行する(図13(B)参照)。こうして腰に対する揉み玉51での揉みや叩き等のマッサージを腰下側から行うことで、背面側からのマッサージとは異なる新たなマッサージ効果を付与することができ、施療効果を高められることとなる。   Further, the control unit 40 stops the advance / retreat motor 58 and operates the lifting motor 57 to raise the kneading balls 51 together with the mechanical unit 50 so that the kneading balls 51 reach just below the waist. In this state, the control unit 40 activates the kneading motor 62 and / or the tapping motor 64 of the drive mechanism unit 60 to execute a massage operation of kneading and / or tapping on the lower waist portion of the kneading balls 51 (FIG. 13). (See (B)). By performing massage such as massage or hitting with the kneading balls 51 on the waist from the lower waist side in this way, a new massage effect different from the massage from the back side can be given, and the treatment effect can be enhanced. .

このように、本実施形態に係るマッサージ機は、背もたれ部13内部に揉み玉51の駆動機構部60を傾動可能に配設する一方、この駆動機構部60における揉み玉支持アーム52を揉み軸部63で支持すると共に、揉み軸部63を傾動軸53上に取付けて、揉み軸部63の中心位置を駆動機構部60の傾動中心である傾動軸53と一致させ、揉み玉51に加わる力が揉み玉支持アーム52及び揉み軸部63を介して傾動軸53にそのまま伝わるようにすることで、揉み玉51側から駆動機構部60を傾動させる駆動部分に不要な力が加わらず、ピニオンギヤ58aをはじめとする傾動用の駆動機構を高い強度のあるものとする必要が無く、この傾動用の駆動機構を簡略化でき、メカユニット50を小型化できると共に、大幅なコストダウンが図れる。   As described above, the massage machine according to the present embodiment disposes the drive mechanism 60 of the kneading balls 51 inside the backrest portion 13 so as to be tiltable, while the kneading ball support arm 52 in the drive mechanism 60 is kneaded. 63, and the squeezing shaft part 63 is mounted on the tilting shaft 53 so that the center position of the squeezing shaft part 63 coincides with the tilting shaft 53 that is the tilting center of the drive mechanism 60, and the force applied to the squeezing ball 51 is increased. By transmitting directly to the tilting shaft 53 via the kneading ball support arm 52 and the kneading shaft portion 63, unnecessary force is not applied to the drive portion that tilts the drive mechanism portion 60 from the kneading ball 51 side, and the pinion gear 58a is moved. It is not necessary to make the drive mechanism for tilting with high strength, and the drive mechanism for tilting can be simplified, the mechanical unit 50 can be downsized, and the cost can be greatly reduced. Achieved.

なお、前記実施形態に係るマッサージ機においては、駆動機構部60で揉み機構をなす揉み軸部63に揉み玉支持アーム52を相対回動可能として取付けると共に、揉み軸部63を傾動軸53上に回動可能に取付けて、傾動軸53が揉み軸部63を介して揉み玉支持アーム52を揺動可能に支持する構成としているが、これに限らず、マッサージ機に揉み機能が無く、駆動機構部60が揉み機構を有しない場合などは、傾動軸に揉み玉支持アームを直接取付けて、傾動軸が揉み玉支持アームを揺動可能に支持する構成とすることもでき、前記同様、施療子としての揉み玉に加わる力が揉み玉支持アームを介して傾動軸にそのまま伝わるようにすることで、駆動機構部の傾動機構に不要な力が加わらず、揉み玉と駆動機構部の傾動動作や傾動停止時における施療動作の信頼性や安全性を高められると共に、駆動機構部の傾動機構を高い強度のあるものとする必要が無く、傾動機構を簡略化でき、メカユニット全体の小型化が図れる。   In the massage machine according to the above embodiment, the kneading ball support arm 52 is attached to the kneading shaft portion 63 that forms a kneading mechanism by the drive mechanism portion 60 so as to be relatively rotatable, and the kneading shaft portion 63 is placed on the tilting shaft 53. The tilting shaft 53 is configured to pivotably support the kneading ball support arm 52 via the kneading shaft portion 63 so as to be swingable. However, the present invention is not limited to this, and the massage machine does not have a kneading function. When the portion 60 does not have a stagnation mechanism, the stagnation ball support arm can be directly attached to the tilting shaft, and the tilting shaft can be configured to support the stagnation ball support arm in a swingable manner. As the force applied to the kneading balls is transmitted to the tilting shaft as it is through the kneading ball support arm, unnecessary force is not applied to the tilting mechanism of the drive mechanism, and the tilting operation of the kneading balls and the drive mechanism Tilt stop With enhanced reliability and safety of the treatment operations during, some with no need to high strength tilt mechanism of the drive mechanism, simplifies the tilting mechanism, thereby the size of the entire mechanical unit.

また、前記実施形態に係るマッサージ機においては、メカユニット50の回転体55にピニオンギヤ部55aを設ける一方、ガイドフレーム20にはラック21を設け、ピニオンギヤ部55aとラック21とを噛合させて、回転する回転体55がガイドフレーム20を上下に走行可能とされる構成としているが、これに限らず、歯車とラックの組合せを用いる以外で、メカユニットの荷重の加わる回転体が、ガイドフレームに対し滑ってずれることなくガイドフレームを上下に走行可能となる構成、例えば、回転体に形成した凹凸に対応する逆の凹凸をガイドフレームに設けて、凹凸の係合で回転体がずれなくガイドフレームを上下に走行可能となるような構成としてもかまわない。   Further, in the massage machine according to the embodiment, the pinion gear portion 55a is provided on the rotating body 55 of the mechanical unit 50, while the guide frame 20 is provided with the rack 21, and the pinion gear portion 55a and the rack 21 are meshed to rotate. However, the present invention is not limited to this, and the rotating body to which the load of the mechanical unit is applied to the guide frame is not limited to this. A configuration in which the guide frame can be moved up and down without slipping and slipping, for example, a reverse unevenness corresponding to the unevenness formed in the rotating body is provided in the guide frame, and the rotating body is not displaced by engagement of the unevenness. It may be configured to be able to run up and down.
