Description

本発明は、座臥姿勢のマッサージ受療者の頸部、体幹、上下肢を、噴流水圧によってマッサージする液圧マッサージ装置に関する。   The present invention relates to a hydraulic massage device that massages the neck, trunk, and upper and lower limbs of a massage recipient in a sitting posture with jet water pressure.

従来から、液体が貯留された液槽内に、液槽一辺方向に沿って移動可能に移動台車を設けたうえで、移動台車に設けた噴射部から開口に向かって噴射液を噴射することで、液槽の開口を覆って設けられた可撓性シートに座臥姿勢で乗り込んだマッサージ受療者の治療部位を噴射液でマッサージする液圧マッサージ装置がある（例えば、特許文献１参照）。   Conventionally, in a liquid tank in which liquid is stored, a movable carriage is provided so as to be movable along the direction of one side of the liquid tank, and then a jet liquid is ejected from an ejection section provided on the movable carriage toward the opening. There is a hydraulic massage device that massages a treatment site of a massage recipient who has entered a flexible sheet covering a liquid tank opening in a sitting posture with a jet liquid (see, for example, Patent Document 1).

特開２００３−０５２７８２JP2003-052782 特開２００５−２６１８２４JP-A-2005-261824

液圧マッサージ装置によるマッサージ施療時においてマッサージ受療者は、シート乗降時等に下肢を床面やシートから持ち上げて体の向きを変える動作を行うことがある。この動作時には、臀部のみを介して全体重が可撓性シートの一部分に印加されてしまって可撓性シートが過剰に撓んでしまうことがある。このようなシートの過剰撓みが生じると、マッサージ受療者がバランスを崩して転倒することが考えられる。このような可撓性シートの過剰な撓みを防止するためには、可撓性シートの撓み性を若干弱める、もしくは剛性を少し強めることが考えられる。しかしながら、このような変更を加えると、可撓性シートが変形しにくくなって噴射液噴射によるマッサージ効果が弱まってしまう。そのため、この対策は有効ではない。   During massage treatment using a hydraulic massage device, a massage recipient may perform an operation of lifting the lower limb from the floor or the seat to change the body orientation when getting on and off the seat. At the time of this operation, the entire weight may be applied to a part of the flexible sheet only through the collar portion, and the flexible sheet may be bent excessively. If such excessive sheet deflection occurs, it is considered that the massage recipient loses balance and falls. In order to prevent such excessive bending of the flexible sheet, it is conceivable to slightly weaken the flexibility of the flexible sheet or slightly increase the rigidity. However, when such a change is added, the flexible sheet is difficult to be deformed, and the massage effect by the jetting liquid jet is weakened. Therefore, this measure is not effective.

また、特許文献２には、液漕の長辺方向の中途部において、可撓性防水シートの下方で液漕の幅方向に掛け渡されるように水槽に固定された補助支持ネットまたはシートを備えた液圧マッサージ装置が開示されている。この構成によれば、液漕の開口を覆う可撓性シートが薄くても、マッサージ受療者は可撓性シートに安定して乗り降りすることができる。   In addition, Patent Document 2 includes an auxiliary support net or sheet fixed to the water tank so as to be spanned in the width direction of the liquid tank below the flexible waterproof sheet in the middle portion in the long side direction of the liquid tank. A hydraulic massage device is disclosed. According to this configuration, even if the flexible sheet covering the opening of the liquid tub is thin, the massage recipient can stably get on and off the flexible sheet.

また、液圧マッサージ装置の可撓性シートの素材として天然ゴムが採用され、この天然ゴム層の一方面（マッサージ受療者が乗り降りする面）に特殊ゴム層が加工形成された可撓性シートが市販されている。しかしながら、この可撓性シートの下方に補助支持ネット等を液槽の幅方向に対して架け渡した場合、マッサージ受療者の乗り降り動作などの繰り返しによって天然ゴム層と補助支持ネット等が擦れ、次第に天然ゴム層が摩耗してしまうという問題点を有していた。 Also, a natural rubber is adopted as a material of the flexible sheet of the hydraulic massage device, and a flexible sheet in which a special rubber layer is processed and formed on one surface of the natural rubber layer (a surface on which a massage recipient gets on and off) is formed. It is commercially available. However, when an auxiliary support net or the like is placed under the flexible sheet in the width direction of the liquid tank, the natural rubber layer and the auxiliary support net or the like are rubbed gradually due to repeated operations such as getting on and off the massage recipient. There was a problem that the natural rubber layer was worn.

したがって本発明は、上述の問題点に鑑みてなされたものであって、マッサージ効果に支障を生じさせることなく可撓性シートの過剰な撓みを抑制するとともに、可撓性シートの摩耗を防止することができる液圧マッサージ装置の提供を主たる目的としている。   Therefore, the present invention has been made in view of the above-described problems, and suppresses excessive bending of the flexible sheet and prevents wear of the flexible sheet without causing any trouble in the massage effect. The main purpose is to provide a hydraulic massage device that can be used.

本発明は、上面に開口を有して液体が貯留された液槽と、前記液槽内に、液槽一辺方向に沿って移動可能に設けられた移動台車と、前記移動台車に設けられて前記開口に向かって噴射液を噴射する噴射部と、前記噴射部に前記噴射液を供給する噴射液供給部と、前記開口を覆って前記液槽に設けられておりマッサージ受療者が治療部位をシート上面に当接させて座臥乗込可能な可撓性シートと、可撓性補強帯と、前記液槽の周囲を囲むケーシングと、を備え、前記可撓性補強帯は、前記可撓性シートの上側にあって前記液槽一辺方向と交差する方向に沿って前記液槽の開口両端間に架設され、前記ケーシングは、前記液槽一辺方向に沿った側面に位置する底部に、窪みが設けられており、前記窪みは、前記可撓性シートに乗降する前記マッサージ受療者の踵が入り込む大きさを有し、且つ、前記可撓性補強帯に対応する位置に設けられている。
The present invention includes a liquid tank having an opening on the upper surface and storing a liquid, a movable carriage provided in the liquid tank so as to be movable along one side of the liquid tank, and the movable carriage. An injection part that injects an injection liquid toward the opening, an injection liquid supply part that supplies the injection liquid to the injection part, and a massage recipient that is provided in the liquid tank so as to cover the opening. A flexible sheet that can come into contact with the upper surface of the sheet and that can be carried on the seat, a flexible reinforcing band, and a casing that surrounds the periphery of the liquid tank , wherein the flexible reinforcing band is the flexible sheet The upper side of the adhesive sheet is installed between both ends of the opening of the liquid tank along a direction intersecting the one side direction of the liquid tank, and the casing is recessed at the bottom located on the side surface along the one side direction of the liquid tank. And the recess is adapted to get on and off the flexible sheet. Sized to di受療's heel enters, and is provided at a position corresponding to the flexible reinforcing strip.

マッサージ受療者はシート乗降時等において下肢を床面やシートから持ち上げて体の向きを変える動作を行うことがあるが、これらの動作時には臀部のみを介して全体重が可撓性シートの一部分に印加されてしまって可撓性シートが過剰に撓んでしまうことがある。このようなシートの過剰撓みが生じると、マッサージ受療者がバランスを崩して転倒することが考えられる。上記構成を有する本発明では、可撓性補強帯により可撓性シートが補強されるので、可撓性シートの過剰な撓みが防止され、可撓性シートが過剰に撓んでマッサージ受療者がバランスを崩して転倒することは未然に防止される。また、ケーシング側面の窪みにより、マッサージ受療者は、踵をケーシングに近づけ易くなって姿勢が安定し、乗降動作がやりやすくなる。さらには、可撓性シートの過剰な撓みを可撓性補強帯の追加により防止しており、可撓性シートの撓み性や剛性に改変を加える必要がない。そのため、マッサージ効果にほとんど影響を与えない。
A massage recipient may perform an action of lifting the lower limbs from the floor or the sheet to change the direction of the body when getting on and off the seat, etc., but during these actions, the overall weight is only part of the flexible sheet through the buttocks. It may be applied and the flexible sheet may be bent excessively. If such excessive sheet deflection occurs, it is considered that the massage recipient loses balance and falls. In the present invention having the above-described configuration, the flexible sheet is reinforced by the flexible reinforcing band, so that excessive bending of the flexible sheet is prevented, and the flexible sheet is excessively bent so that the massage recipient can Falling out of balance is prevented in advance. Further, the depression on the side surface of the casing makes it easier for the massage recipient to approach the heel to the casing, stabilizes the posture, and facilitates the getting-on / off operation. Furthermore, excessive bending of the flexible sheet is prevented by adding a flexible reinforcing band, and it is not necessary to modify the flexibility and rigidity of the flexible sheet. Therefore, it hardly affects the massage effect.

また、本発明には、前記可撓性補強帯の前記液漕一辺方向の寸法を乗降する前記マッサージ受療者の臀部が食み出さない程度の最小寸法に設定するという態様がある。この態様によれば、マッサージ受療者が可撓性シート上で横臥した際に可撓性補強帯の端部がマッサージ受療者の背中部に当接し難くなり、マッサージ受療者は背中部に可撓性補強帯の端部が当接することに起因する違和感を感じることなく、心地よいマッサージを受けることができる。Moreover, in this invention, there exists an aspect of setting to the minimum dimension of the extent which the buttocks of the said massage recipient who gets on and off the said dimension of the said liquid reinforcement one side direction of the said flexible reinforcement band does not protrude. According to this aspect, when the massage recipient lies down on the flexible sheet, the end of the flexible reinforcement band does not come into contact with the back portion of the massage recipient, and the massage recipient can flex to the back portion. A comfortable massage can be received without feeling uncomfortable due to the contact of the end portions of the elastic reinforcing band.

また、本発明には、前記可撓性補強帯の端部に断面視口状の口状部を形成し、前記口状部に押さえ金具を挿通し、前記押さえ金具を介して前記液槽の縁上端に連結固定するようにした、という態様がある。この態様によれば、押さえ金具を介することなく可撓性補強帯の端を直接液槽の縁上端に連結固定する場合に比して可撓性補強帯の端を液槽の縁上端に連結固定する作業が容易に行えるため、作業効率を向上できる。また、可撓性補強帯が設けられる部位はマッサージ受療者が実際に乗り降りを繰り返し行う部分であるから、可撓性補強帯のずれなどが一番発生し易いところとなっているが、本発明によれば押え金具を介して連結固定するようにしたので、縁上端に対して可撓性補強帯を強固に連結固定でき、乗り降りを繰り返しても可撓性補強帯のずれが発生し難いものとなる。Further, in the present invention, a mouth portion having a mouth shape in cross section is formed at an end portion of the flexible reinforcing band, a press fitting is inserted into the mouth portion, and the liquid tank is inserted through the press fitting. There is an aspect in which the upper end of the edge is connected and fixed. According to this aspect, the end of the flexible reinforcement band is directly connected to the upper edge of the liquid tank without connecting the holding metal fitting to the upper edge of the liquid tank. Since the fixing work can be easily performed, the work efficiency can be improved. Further, since the part where the flexible reinforcement band is provided is a part where the massage recipient actually repeats getting on and off, the displacement of the flexible reinforcement band is most likely to occur. According to the above, since it is connected and fixed through the presser fitting, the flexible reinforcing band can be firmly connected and fixed to the upper edge of the edge, and the flexible reinforcing band is not easily displaced even when repeatedly getting on and off. It becomes.

また、本発明には、前記可撓性補強帯に両面ファスナの雌部材または雄部材が設けられ、前記可撓性シート上に敷設するシーツ部材に前記可撓性補強帯の雌部材または雄部材に対応する雄部材または雌部材が設けられる、という態様がある。この態様によれば、可撓性補強帯の上方から可撓性シート面に対してシーツ部材を敷設する場合に、シーツ部材の雌部材または雄部材と可撓性補強帯の雄部材または雌部材に結合することでシーツ部材の一部を可撓性補強帯に対して固定することが可能となる。In the present invention, a female member or a male member of a double-sided fastener is provided on the flexible reinforcing band, and a female member or a male member of the flexible reinforcing band is provided on a sheet member laid on the flexible sheet. There is a mode in which a male member or a female member corresponding to is provided. According to this aspect, when the sheet member is laid on the flexible sheet surface from above the flexible reinforcing band, the female member or male member of the sheet member and the male member or female member of the flexible reinforcing band It becomes possible to fix a part of the sheet member to the flexible reinforcing band by coupling to the flexible reinforcing band.

また、本発明において、前記窪みは、前記液槽一辺方向中央を含む位置に設けられていることが好ましい。
Moreover, in this invention , it is preferable that the said hollow is provided in the position containing the said liquid tank one side direction center.

また、本発明において、前記窪みは、前記可撓性補強帯に対応する位置における窪みの凹み度合が、他の位置における窪みの凹み度合より大きい窪みであることが好ましい。
Moreover, in this invention, it is preferable that the said hollow is a hollow in which the hollow degree of the hollow in the position corresponding to the said flexible reinforcement belt is larger than the hollow degree of the hollow in another position.

本発明によれば、マッサージ効果に支障を生じさせることなく可撓性シートの過剰な撓みを抑制することができる。また、例えば、可撓性シートの素材として天然ゴムを採用し、且つこの天然ゴム層の一方面（マッサージ受療者が乗り降りする面）に特殊ゴム層を加工形成したものを可撓性シートとして採用した場合であっても、可撓性補強帯を可撓性シートの上側に架設しているため、マッサージ受療者の乗り降り動作などの繰り返しによって天然ゴム層と可撓性補強帯とが擦れて次第に天然ゴム層が摩耗してしまうという心配が無用となる。   According to the present invention, it is possible to suppress excessive bending of the flexible sheet without causing any trouble in the massage effect. In addition, for example, natural rubber is used as the material of the flexible sheet, and a special rubber layer processed and formed on one side of this natural rubber layer (the surface on which the massage recipient gets on and off) is used as the flexible sheet. Even in this case, since the flexible reinforcement band is installed on the upper side of the flexible sheet, the natural rubber layer and the flexible reinforcement band are gradually rubbed due to repetition of the getting on and off operation of the massage recipient. There is no need to worry about the natural rubber layer being worn away.

The hydraulic massage device 100 includes a liquid tank 1, a movable carriage 2, first to fourth injection units 3A to 3D, an injection liquid supply unit 4, a flexible sheet 5, a flexible reinforcing band 6, and a carriage moving mechanism. 7 and a casing 8.

液槽１は、上面に開口１ａを有して水等の液体Ａが貯留される直方体形状（平面視楕円形状を含む）の内容積を有している。ケーシング８は、全周にわたって液槽１の側面を覆っている。移動台車２は、図２に示すように、転動輪２ａを有している。移動台車２は、転動輪２ａを液槽１内の底部で転動させることで、液槽１の一辺方向１ｂに沿って水平移動可能となっている。なお、本実施形態では、液槽１は一方辺が他方辺より長い形状を有しており、長い方の一方辺に沿った方向を一辺方向１ｂとしている。   The liquid tank 1 has an internal volume of a rectangular parallelepiped shape (including an elliptical shape in plan view) in which an upper surface has an opening 1a and stores a liquid A such as water. The casing 8 covers the side surface of the liquid tank 1 over the entire circumference. As shown in FIG. 2, the movable carriage 2 has rolling wheels 2a. The movable carriage 2 can move horizontally along one side direction 1 b of the liquid tank 1 by rolling the rolling wheel 2 a at the bottom of the liquid tank 1. In the present embodiment, the liquid tank 1 has a shape in which one side is longer than the other side, and a direction along one longer side is defined as a one-side direction 1b.

第１〜第４の噴射部３Ａ〜３Ｄは、外部から供給される噴射液Ｂを液槽底部側から開口１ａに向かって噴射している。噴射液供給部４は、第１〜第４の噴射部３Ａ〜３Ｄに噴射液Ｂを供給している。   The 1st-4th injection parts 3A-3D are injecting the injection liquid B supplied from the outside toward the opening 1a from the liquid tank bottom part side. The injection liquid supply unit 4 supplies the injection liquid B to the first to fourth injection units 3A to 3D.

可撓性シート５はゴムシート材からなり、液槽１に、開口１ａの全部を覆って取り付けられており、マッサージ受療者Ｃが治療部位をシート上面に当接させて座臥状態で乗込可能となっている。具体的には可撓性シート５は、図５に示すように、シート全周が液槽１の縁上端１ｃにボルト止めされることで、液槽１に装着されている。なお、本実施形態では、可撓性シート５は、開口１ａの全面を覆って取り付けられている。   The flexible sheet 5 is made of a rubber sheet material, and is attached to the liquid tank 1 so as to cover the entire opening 1a, and the massage recipient C gets in a sitting position with the treatment site in contact with the upper surface of the sheet. It is possible. Specifically, as shown in FIG. 5, the flexible sheet 5 is attached to the liquid tank 1 by bolting the entire periphery of the sheet to the edge upper end 1 c of the liquid tank 1. In the present embodiment, the flexible sheet 5 is attached so as to cover the entire surface of the opening 1a.

可撓性補強帯６は、高強度・高弾性率などの特性を持つ高性能・高機能繊維のシート部材もしくは網状部材からなる。高性能・高機能繊維としては、パラ系アラミド繊維、超高分子量ポリエチレン繊維、ポリアリレート繊維、ＰＢＯ繊維、炭素繊維などを採用することができる。パラ系アラミド繊維などの高性能・高機能繊維は、高弾性率の特性を有しているためマッサージの妨げとならず、しかも高強度の特性も備えているので、体格が大きく体重の重いマッサージ受療者が乗り降しても充分に耐え得ることができる。また、高性能・高機能繊維は耐衝撃性や耐摩耗性を有しており、使用に伴う経年劣化による伸びが少ないので、他の繊維を採用した場合に比して長期間使用することができ、頻繁に可撓性補強帯を交換することを回避でき、ランニングコストを低減でき経済的である。可撓性補強帯６は、可撓性シート５の上側にあって液槽１の一辺方向１ｂと交差する方向に沿って開口１ａ上に架設されている。可撓性補強帯６は、マッサージ受療者Ｃが可撓性シート５に乗降する際に、マッサージ受療者Ｃの臀部が当接する部位に設けられている。なお、可撓性補強帯６が設けられる臀部が当接する部位とは、マッサージ受療者Ｃが一辺方向１ｂに沿って可撓性シート５上に横臥した際にマッサージ受療者Ｃの腰部から臀部、またはその近傍部が当接する範囲のことをいう。また、可撓性補強帯の液漕１の一辺方向に沿う寸法は乗降するマッサージ受療者の臀部が食み出さない程度の寸法（４００ｍｍ〜５００ｍｍ）に設定されている。 The flexible reinforcing band 6 is made of a sheet member or a net-like member made of high-performance and high-performance fibers having characteristics such as high strength and high elastic modulus. As the high performance / high function fiber, para-aramid fiber, ultra high molecular weight polyethylene fiber, polyarylate fiber, PBO fiber, carbon fiber, and the like can be used. High-performance and high-performance fibers such as para-aramid fibers do not interfere with massage because they have high elastic modulus characteristics, and also have high-strength characteristics.

なお、このような形状を有する窪み８ａを、一辺方向１ｂに沿った液槽１の側面に位置するケーシング８の部位の全体にわたって設けてもよいが、本実施形態では次のように設けている。すなわち、マッサージ受療者Ｃが一辺方向１ｂに沿った液槽側面側の液槽載置面Ｅから可撓性補強帯６に乗降するマッサージ受療者Ｃの踵Ｃａや爪先に対向する位置とその近傍位置とにおける窪み８ａ（図３参照）の凹み度合を、他の位置における窪み８ａ（図４参照）の凹み度合より大きくしている。ここでいう窪み度合とは、一辺方向１ｂと直交する方向に沿った窪み８ａの断面積や、窪み形成部位の最底辺において、一辺方向１ｂと直交する方向に沿った窪み表面部位と窪み無しケーシングの表面部位との間の離間間隔を一例として挙げることができる。   In addition, although the hollow 8a which has such a shape may be provided over the whole site | part of the casing 8 located in the side surface of the liquid tank 1 along the one side direction 1b, in this embodiment, it provides as follows. . That is, the position where the massage recipient C faces the heel Ca or the toe of the massage recipient C who gets on and off the flexible reinforcing band 6 from the liquid tank mounting surface E on the side surface of the liquid tank along the one side direction 1b and the vicinity thereof The dent degree of the dent 8a (see FIG. 3) at the position is larger than the dent degree of the dent 8a (see FIG. 4) at the other positions. Here, the degree of depression refers to the cross-sectional area of the depression 8a along the direction orthogonal to the one-side direction 1b, or the depression surface portion and the depression-free casing along the direction perpendicular to the one-side direction 1b at the bottom of the depression formation portion. As an example, a spacing interval between the surface portion and the surface portion can be given.

次に以上の構成を備えた液圧マッサージ装置１００の動作を説明する。図６に示すように、液圧マッサージ装置１００の可撓性シート５の上面にマッサージ受療者Ｃが、治療部位をシート上面に当接させて座臥（例えば横臥）する。この状態で、マッサージ受療者Ｃもしくは、マッサージ施療介添者Ｄが装置１００の動作を開始するスイッチをオンにする。すると、吸水ポンプ部１３が駆動して液槽１から液体Ａを吸水し、吸水した液体Ａを加圧して噴射液Ｂにし、さらにこのようにして発生させた噴射液Ｂを曲折配管１４を介して移動台車２の台車内流路２６に圧送する。台車内流路２６に圧送された噴射液Ｂは、軸内流路２０Ａａ〜２０Ｄａと噴射部内流路２１Ａａ〜２１Ｄａを経て、第１〜第４の噴射部３Ａ〜３Ｄの第１〜第４の噴射ノズル２２Ａ〜２２Ｄまでさらに圧送される。各噴射ノズル２２Ａ〜２２Ｄは、圧送されてきた噴射液Ｂを開口１ａに向かって液槽１内の液体Ａ中に噴射する。噴射された噴射液Ｂは、可撓性シート５の裏面に突き当たったうえで液槽１内の液体Ａ中に拡散する。その際、可撓性シート５が噴射液Ｂの噴射によって部分的に上方側に屈曲変形し、屈曲シート部位に位置するマッサージ受療者Ｃの体表部位をマッサージする。   Next, operation | movement of the hydraulic massage apparatus 100 provided with the above structure is demonstrated. As shown in FIG. 6, the massage recipient C sits on the upper surface of the flexible sheet 5 of the hydraulic massage apparatus 100 with the treatment site in contact with the upper surface of the sheet (for example, lying down). In this state, the massage recipient C or the massage treatment attendant D turns on the switch for starting the operation of the device 100. Then, the water absorption pump unit 13 is driven to absorb the liquid A from the liquid tank 1, pressurize the absorbed liquid A into the injection liquid B, and further generate the injection liquid B thus generated via the bent pipe 14. Then, it is pumped to the bogie passage 26 of the moving carriage 2. The injection liquid B pumped to the bogie internal flow path 26 passes through the in-axis flow paths 20Aa to 20Da and the injection section internal flow paths 21Aa to 21Da, and the first to fourth injection sections 3A to 3D. Further pressure is fed to the injection nozzles 22A to 22D. Each of the spray nozzles 22A to 22D sprays the spray liquid B that has been fed into the liquid A in the liquid tank 1 toward the opening 1a. The jetted liquid B is abutted against the back surface of the flexible sheet 5 and then diffuses into the liquid A in the liquid tank 1. At that time, the flexible sheet 5 is partially bent and deformed upward by the injection of the spray liquid B, and massages the body surface part of the massage recipient C located at the bent sheet part.

以上の噴射液Ｂの噴射を行いながら、チェーン駆動部１０の駆動モータ１０ａが任意に正逆回転することで、移動台車２が一辺方向１ｂに沿って反復直線移動する。このとき、移動台車２は、第１、第２のねじギア２５Ａ、２５Ｂの連結孔２５Ａａ、２５Ｂａが断面矩形状の軸９に挿通することで、その直線移動が案内される。これにより、移動台車２に装着されている第１〜第４の噴射部本体２１Ａ〜２１Ｄの第１〜第４の噴射ノズル２２Ａ〜２２Ｄが反復直線移動する。   While the jet liquid B is being jetted as described above, the drive motor 10a of the chain drive unit 10 arbitrarily rotates forward and backward, whereby the movable carriage 2 repeatedly moves linearly along the one-side direction 1b. At this time, the moving carriage 2 is guided by the linear movement of the connecting holes 25Aa and 25Ba of the first and second screw gears 25A and 25B through the shaft 9 having a rectangular cross section. Thereby, the 1st-4th injection nozzle 22A-22D of the 1st-4th injection part main bodies 21A-21D with which the mobile trolley 2 was mounted | worn repeats linear movement.

さらに、この状態で回転駆動部１１が軸９を正逆回転駆動することで、軸９によって第１、第２のねじギア２５Ａ、２５Ｂが正逆回転される。すると、第１、第２のねじギア２５Ａ、２５Ｂに連動連結された第１、第２の受動ギア２４Ａ、２４Ｂが回転駆動され、これにより、第１、第３の回転筒１８Ａ、１８Ｃと第１、第３の連結ギア２３Ａ、２３Ｃと第１、第３の噴射部本体２１Ａ、２１Ｃとが回転する。さらに第１、第３の連結ギア２３Ａ、２３Ｃに噛合している第２、第４の連結ギア２３Ｂ、２３Ｄが回転し、それに伴って第２、第４の噴射部本体２１Ｂ、２１Ｄが回転する。このとき、第１、第３の噴射部本体２１Ａ、２１Ｃと第２、第４の噴射部本体２１Ｂ、２１Ｄとは互いに逆方向に回転する。これにより、第１〜第４の噴射部本体２１Ａ〜２１Ｄに装着されている第１〜第４の噴射ノズル２２Ａ〜２２Ｄが第１〜第４の噴射軸部２０Ａ〜２０Ｄの軸心を中心にして回動する。   Further, in this state, the rotation driving unit 11 drives the shaft 9 to rotate forward and backward, whereby the first and second screw gears 25A and 25B are rotated forward and backward by the shaft 9. Then, the first and second passive gears 24A and 24B interlocked with the first and second screw gears 25A and 25B are rotationally driven, whereby the first and third rotary cylinders 18A and 18C and the first The first and third connection gears 23A and 23C and the first and third injection unit main bodies 21A and 21C rotate. Further, the second and fourth connection gears 23B and 23D meshing with the first and third connection gears 23A and 23C rotate, and the second and fourth injection unit main bodies 21B and 21D rotate accordingly. . At this time, the first and third injection unit main bodies 21A and 21C and the second and fourth injection unit main bodies 21B and 21D rotate in directions opposite to each other. Thereby, the 1st-4th injection nozzles 22A-22D with which the 1st-4th injection part main bodies 21A-21D are equipped are centered on the axial center of the 1st-4th injection shaft parts 20A-20D. Rotate.

以上の反復直線移動／反復回動移動を受けた第１〜第４の噴射ノズル２２Ａ〜２２Ｄは、一辺方向１ｂに沿って複雑な移動軌跡を描きながら、液槽１内を移動する。これによりマッサージ受療者Ｃは、複雑な移動軌跡を描きながら移動する第１〜第４の噴射ノズル２２Ａ〜２２Ｄが噴射する噴射液Ｂによって念入りかつ丁寧にマッサージされる。   The first to fourth injection nozzles 22A to 22D that have received the above repetitive linear movement / repetitive rotation movement move in the liquid tank 1 while drawing a complicated movement locus along the one-side direction 1b. As a result, the massage recipient C is carefully and carefully massaged by the jet liquid B ejected by the first to fourth jet nozzles 22A to 22D that move while drawing a complicated movement trajectory.

液圧マッサージ装置１００では、可撓性補強帯６を設けており、これによって可撓性シート５が補強されるので、図７に示すように、可撓性シート５の過剰な撓みが防止され、可撓性シート５が過剰に撓んでマッサージ受療者Ｃがバランスを崩して転倒することは未然に防止される。なお、図７において、実線で示した可撓性シート５の形状は、可撓性性補助帯６を設けた本実施形態の液圧マッサージ装置１００における可撓性シート５の撓み込み具合を示しており、仮想線で示した可撓性シート５の形状は、可撓性性補助帯６を設けていない従来例における可撓性シート５の撓み込み具合を示している。   In the hydraulic massage device 100, the flexible reinforcing band 6 is provided, and thereby the flexible sheet 5 is reinforced, so that excessive bending of the flexible sheet 5 is prevented as shown in FIG. Further, it is prevented that the flexible sheet 5 is excessively bent and the massage recipient C loses balance and falls. In FIG. 7, the shape of the flexible sheet 5 indicated by a solid line indicates the bending state of the flexible sheet 5 in the hydraulic massage device 100 of the present embodiment provided with the flexible auxiliary band 6. The shape of the flexible sheet 5 indicated by the phantom line indicates the bending state of the flexible sheet 5 in the conventional example in which the flexible auxiliary band 6 is not provided.

なお、通常、マッサージ受療者Ｃの転倒は、乗降時に臀部のみを可撓性シートＣに当接させる行為中に生じることが多い。そこで、液圧マッサージ装置１００では、マッサージ受療者Ｃが可撓性シート５に乗降する際にマッサージ受療者Ｃの臀部が当接する部位に可撓性補強帯６を設けている。そのため、乗降時に臀部のみを可撓性シート５に当接させる行為により生じる可撓性シート５の過剰な撓みを確実に防止してマッサージ受療者Ｃの転倒を確実に防ぐことができる。さらには、可撓性シート５の過剰な撓みを可撓性補強帯６の追加により防止しており、可撓性シート５の撓み性や剛性に改変を加えられていない。そのため、マッサージ効果にほとんど影響を与えることなく可撓性シート５の過剰な撓みが防止されている。   In general, the fall of the massage recipient C often occurs during the act of bringing only the buttocks into contact with the flexible sheet C when getting on and off. Therefore, in the hydraulic massage device 100, the flexible reinforcing band 6 is provided at a site where the massage recipient C contacts the buttocks when the massage recipient C gets on and off the flexible sheet 5. Therefore, excessive bending of the flexible sheet 5 caused by the action of bringing only the buttocks into contact with the flexible sheet 5 when getting on and off can be surely prevented, and the massage recipient C can be prevented from falling over. Furthermore, excessive bending of the flexible sheet 5 is prevented by the addition of the flexible reinforcing band 6, and the flexibility and rigidity of the flexible sheet 5 are not modified. Therefore, excessive bending of the flexible sheet 5 is prevented without substantially affecting the massage effect.

また、液圧マッサージ装置１００では、ケーシング８の底部に窪み８ａを設けるので、次のような効果が得られる。すなわち、乗降時においてマッサージ受療者Ｃは、一辺方向１ｂに沿った液槽側面１ｄに位置する床面（装置載置面）Ｅから可撓性シート５に腰を落とす、もしくは腰を落としている可撓性シート５から起立する。その際、マッサージ受療者Ｃは、液槽側面１ｄに位置するケーシング８の底部にできるだけ踵Ｃａや爪先を近づけると、姿勢が安定して動作がやりやすくなる。液圧マッサージ装置１００では、液槽側面１ｄに位置するケーシング８の底部に、可撓性シート５に乗降するマッサージ受療者Ｃの踵Ｃａや爪先またはマッサージ施療介添者Ｄの爪先Ｄａが入り込む大きさを有する窪み８ａを設けている。これにより、マッサージ受療者Ｃは、踵Ｃａや爪先をケーシング８に近づけ易くなって姿勢が安定し、乗降動作がやりやすくなる。   Moreover, in the hydraulic massage apparatus 100, since the hollow 8a is provided in the bottom part of the casing 8, the following effects are acquired. That is, at the time of getting on and off, the massage recipient C drops his / her waist on the flexible sheet 5 from the floor surface (device mounting surface) E located on the liquid tank side surface 1d along the one-side direction 1b. Stands up from the flexible sheet 5. At that time, when the massage recipient C brings the heel Ca or the toe as close as possible to the bottom of the casing 8 located on the liquid tank side surface 1d, the posture becomes stable and the operation becomes easy. In the hydraulic massage apparatus 100, the size of the massage recipient C who gets on and off the flexible sheet 5 and the toe Da of the massage treatment assistant D or the toe Da of the massage treatment attendant D enter the bottom of the casing 8 located on the liquid tank side surface 1d. The depression 8a having the above is provided. As a result, the massage recipient C can easily bring the heel Ca and the toes close to the casing 8, stabilize the posture, and easily perform the getting-on / off operation.

また、マッサージ動作中の液圧マッサージ装置１００にマッサージ施療介添者Ｄが近づいて液圧マッサージ装置１００の操作やマッサージ受療者Ｃの介添えを行うことがある。その際、マッサージ施療介添者Ｄの爪先Ｄａも窪み８ａに入り込むので、マッサージ施療介添者Ｄは液圧マッサージ装置１００に近づきやすくなって、操作や介添えが容易になる。さらには、窪み８ａを設けることでマッサージ受療者Ｃの踵Ｃａや爪先、もしくはマッサージ施療介添者Ｄの爪先Ｄａがケーシング８に接触しにくくなるため、ケーシング接触に起因する踵Ｃａや爪先Ｄａの創傷や、踵Ｃａや爪先Ｄａの接触に起因するケーシング８の汚れを未然に防ぐこともできる。   Moreover, the massage treatment attendant D may approach the hydraulic massage apparatus 100 during the massage operation, and the hydraulic massage apparatus 100 may be operated or the massage recipient C may be accompanied. At that time, the toe Da of the massage treatment attendant D also enters the recess 8a, so that the massage treatment attendant D can easily approach the hydraulic massage device 100, and operation and assistance are facilitated. Furthermore, since the heel Ca and the toe of the massage recipient C or the toe Da of the massage treatment attendant D are less likely to contact the casing 8 by providing the depression 8a, the wound of the heel Ca and the toe Da caused by the casing contact. In addition, it is possible to prevent the casing 8 from being contaminated due to the contact between the heel Ca and the toe Da.

さらには、液圧マッサージ装置１００では、液槽側面１ｄ側の液槽載置面Ｅから可撓性補強帯６に乗降するマッサージ受療者Ｃの踵Ｃａや爪先に対向する位置とその近傍位置とにおける窪み８ａの凹み度合を、他の位置における前記窪みの凹み度合より大きくしているので、マッサージ受療者Ｃの踵Ｃａや爪先をケーシング８にさらに確実に近づけることが可能となる。   Furthermore, in the hydraulic massage device 100, the position opposite to the heel Ca or the toe of the massage recipient C who gets on and off the flexible reinforcing band 6 from the liquid tank mounting surface E on the liquid tank side surface 1d side, and the vicinity thereof Since the dent degree of the dent 8a is larger than the dent degree of the dent at other positions, it is possible to bring the heel Ca and the toe of the massage recipient C closer to the casing 8 more reliably.

なお、図３は、可撓性補強帯６を設けた部位における窪み８ａの形状を示し、図４は可撓性補強帯６を設けていない部位における窪み８ａの形状を示している。   3 shows the shape of the recess 8a in the portion where the flexible reinforcing band 6 is provided, and FIG. 4 shows the shape of the recess 8a in the portion where the flexible reinforcing band 6 is not provided.

本発明は上述の実施形態に限定されることなく、本発明の趣旨を逸脱しない範囲において適宜変更が可能である。例えば、可撓性補強帯６の帯両端６ａの液槽１の縁上端１ｃへの連結・固定方法は上述の実施形態に限定されるものではなく、例えば、可撓性補強帯６の帯両端６ａに設けたスライド式ファスナ等により可撓性補強帯６が着脱自在となるように構成してもよい。こうすれば可撓性補強帯６の着脱動作が一層容易なものとなり、可撓性補強帯６の手入れや着脱後の可撓性シート５上の清掃が一段と行い易くなる。   The present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the spirit of the present invention. For example, the method of connecting and fixing the band ends 6a of the flexible reinforcing band 6 to the edge upper end 1c of the liquid tank 1 is not limited to the above-described embodiment. You may comprise so that the flexible reinforcement band 6 can be attached or detached freely with the slide type fastener etc. which were provided in 6a. This makes it easier to attach and detach the flexible reinforcing band 6, and makes it easier to care for the flexible reinforcing band 6 and to clean the flexible sheet 5 after the attachment and detachment.
