Description

本発明は、振動による刺激を与えることにより足裏をマッサージするマッサージ器に関する。   The present invention relates to a massager that massages a sole by applying stimulation by vibration.

人体の足の裏は、末梢神経と動脈の毛細血管が集中している。そのため足裏に多く分布するツボを押圧して前記末梢神経を刺激するとともに血行の促進を行うことにより、疲労回復と全身諸器官の機能を活性化できることが古くから知られており、足裏指圧、竹踏みなどの健康増進療法が広く普及している。   Peripheral nerves and arterial capillaries are concentrated on the soles of the human body. For this reason, it has been known for a long time that stress can be recovered and the functions of various organs can be activated by stimulating the peripheral nerves by pressing acupuncture points distributed a lot on the soles of the feet and promoting blood circulation. Health promotion therapies such as bamboo walking are widely used.

そして前記足裏健康法を手軽に行なえしかもその効果を一層高めるため、従来から用いられてきた踏み竹に替え、電動モータを用いて発生する振動により足裏を刺激するマッサージ器が提案されている(例えば、特許文献1参照)。   And in order to perform the above-mentioned foot health method easily and to further enhance its effect, a massager that stimulates the sole by vibration generated by using an electric motor is proposed in place of the traditional bamboo. (For example, refer to Patent Document 1).

前記マッサージ器は図10に示すように、つま先側を枢支された足載せ台aの踵側が、電動モータmの回転により足載せ台aを上下に駆動する駆動機構bと、押しバネcを具えた弾性機構gとで支持されている。前記駆動機構bは、電動モータmの回転がベルト減速機構eを介して伝達される回転軸b1と、該回転軸b1に対して中心軸が偏芯して形成された偏芯部b2と、該偏芯部b2に下端を枢支されかつ上端が足載せ台aを枢着されるロッドb3とを含み構成されている。そのためこのマッサージ器は、前記ロッドb3が電動モータmの回転により上死点h1と下死点h2の間で上下動することにより足載せ台aに上下の振動が生じ、その結果足載せ台a上に載置された足裏を前記振動により刺激することができる。   As shown in FIG. 10, the massage device includes a driving mechanism b that drives the footrest a up and down by the rotation of the electric motor m, and a pressing spring c on the heel side of the footrest a that is pivotally supported on the toe side. It is supported by the provided elastic mechanism g. The drive mechanism b includes a rotation shaft b1 through which the rotation of the electric motor m is transmitted via a belt reduction mechanism e, an eccentric portion b2 formed by eccentrically forming a central axis with respect to the rotation shaft b1, The eccentric part b2 includes a rod b3 pivotally supported at the lower end and pivotally attached to the footrest a at the upper end. For this reason, in this massager, the rod b3 moves up and down between the top dead center h1 and the bottom dead center h2 by the rotation of the electric motor m, so that vertical vibration is generated in the footrest a. As a result, the footrest a The sole placed on the top can be stimulated by the vibration.

前記弾性機構gは、伸縮方向を垂直に向けて足載せ台a踵部の下部に配された押しバネcからなり、足載せ台aに負荷する使用者の体重に抗する上向きのバネ力により足載せ台aを上方へ付勢している。これにより電動モータmの駆動負荷を低減している。   The elastic mechanism g is composed of a push spring c disposed at the lower part of the footrest a with the direction of expansion and contraction being perpendicular, and by an upward spring force that resists the weight of the user loaded on the footrest a. The footrest a is urged upward. Thereby, the driving load of the electric motor m is reduced.

ところで、前記足裏を押圧する際、足裏に向けて最も深く押さえ込んだ位置での押圧力を高めるほど前記末梢神経を有効に刺激するとともに血行を促進する効果が大きい。従って前記マッサージ器では足載せ台aが上昇した時、載置される足裏を強く押し上げ、しかもその時の上昇速度を速めて足裏を鋭く押圧することにより、末梢神経への刺激を高めマッサージ効果を顕著とすることができる。   By the way, when pressing the sole, the peripheral nerve is effectively stimulated and the blood circulation is promoted more effectively as the pressing force at the position where the foot is pressed deepest toward the sole is increased. Therefore, in the massage device, when the footrest a rises, the foot to be placed is pushed up strongly, and the rate of rise at that time is accelerated to push the sole sharply, thereby enhancing stimulation to the peripheral nerves and a massage effect Can be conspicuous.

しかしながら、前記従来のマッサージ器では、足載せ台aが上昇するに従い押しバネcは伸長してバネ力を減じ、図10に示すように、上死点h1におけるバネ力f1は下死点h2でのバネ力f2よりも小さくなる。そのため足載せ台aが上死点h1近傍へと上昇した時に、足裏を押圧する力がむしろ低下し、しかもバネ力の低下に伴って電動モータmの駆動負荷が増加するため、回転速度も低下する。その結果足裏に振動による刺激が加えられても、マッサージのポイントとなる足載せ台aの上昇時における押圧力および押圧速度が双方共不足して、例え長時間施療してもマッサージ効果が得られないという問題がある。   However, in the conventional massage device, as the footrest a rises, the push spring c expands to reduce the spring force, and as shown in FIG. 10, the spring force f1 at the top dead center h1 is at the bottom dead center h2. Is smaller than the spring force f2. Therefore, when the footrest a rises to the vicinity of the top dead center h1, the force for pressing the sole is rather reduced, and the driving load of the electric motor m is increased as the spring force is reduced. descend. As a result, even if stimulation by vibration is applied to the sole of the foot, both the pressing force and the pressing speed when the footrest a, which is the point of massage, is raised are insufficient, and a massage effect can be obtained even if it is treated for a long time. There is a problem that can not be.

本発明は、前記したマッサージ器が有する問題点を解消し、足載せ台を上下動させる駆動部は、電動機と、その回転により、前記足載せ台を上下動しかつ足載せ台が下方位置から上方位置に上昇するに従い、強さを増大する昇降手段とを具えることを基本とし、短時間の使用で顕著なマッサージ効果が得られるマッサージ器の提供を課題としている。   The present invention eliminates the problems of the massage device described above, and the drive unit for moving the footrest up and down moves the footrest vertically by the electric motor and its rotation, and the footrest is moved from the lower position.

以下、本発明の実施の一形態を図示例とともに説明する。図1はマッサージ器1の分解斜視図、図2は平面図、図3は要部を説明する正面図である。本発明のマッサージ器1は、図1に示すように基台2と、足載せ台3と、この足載せ台3を上下動させる駆動部4とからなり、足載せ台3が細かく上下動して生じる振動により足載せ台3の上に載る載置者の足裏を加圧刺激してマッサージするものである。   Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view of the massage device 1, FIG. 2 is a plan view, and FIG. 3 is a front view illustrating the main part. As shown in FIG. 1, the massage device 1 of the present invention comprises a base 2, a footrest 3, and a drive unit 4 that moves the footrest 3 up and down. The footrest 3 moves up and down finely. In this way, the soles of the mounter placed on the footrest 3 are massaged by applying pressure to the footrest 3 due to the vibration generated.

前記基台2は、図1、3に示すように、略円盤状をなし、上側中央に装置部分を配置しうる凹部21を有するとともに床面などに安定して設置するための扁平なゴム足22を下面に複数隔設している。   As shown in FIGS. 1 and 3, the base 2 has a substantially disc shape, and has a concave portion 21 in which the device portion can be arranged at the upper center, and a flat rubber foot for stable installation on a floor surface or the like. A plurality of 22 are provided on the lower surface.

前記足載せ台3は、昇降板9とカバー体11とからなる。前記昇降板9は、本形態では水平な略矩形板状をなし、下側に補強リブを形成するとともにつま先側端部の両側に一対の支持片23、23を突設している。前記支持片23、23は、前記基台2に立設された一対の支持枠12、12に各々支持軸P1により枢着され、これにより前記昇降板9は、基台2に対して前記支持軸P1を中心として踵側が上下動可能に支持される。   The footrest 3 includes an elevating plate 9 and a cover body 11. In the present embodiment, the elevating plate 9 has a horizontal, substantially rectangular plate shape. The elevating plate 9 has a reinforcing rib on the lower side and a pair of support pieces 23 and 23 projecting from both sides of the toe side end. The support pieces 23, 23 are pivotally attached to a pair of support frames 12, 12 erected on the base 2 by support shafts P 1, whereby the elevating plate 9 is supported by the base 2. The heel side is supported so as to be movable up and down around the axis P1.

前記カバー体11は、本形態では図1、3に示すように、下側に前記昇降板9および前記基台2の凹部21を上から覆うへこみを有する略円盤状をなし、その上面に平面視略足形状に盛り上がった左右一対の足型部10を形成している。カバー体11は、前記昇降板9上に載置されるとともに図示されないビスにより前記昇降板9に固着され、そのためカバー体11は昇降板9と一体となって上下動しうる。なおカバー体11は、側方に張り出して形成した鍔部43の下面に、手で持上げる際に指掛かりとなる一対の凹部44、44を有する。   In this embodiment, as shown in FIGS. 1 and 3, the cover body 11 has a substantially disk shape having a dent that covers the elevating plate 9 and the concave portion 21 of the base 2 from above, and a flat surface on the upper surface thereof. A pair of left and right foot mold portions 10 swelled in a generally leg shape is formed. The cover body 11 is placed on the elevating plate 9 and is fixed to the elevating plate 9 with screws (not shown), so that the cover body 11 can move up and down integrally with the elevating plate 9. In addition, the cover body 11 has a pair of recessed parts 44 and 44 used as a finger hook when raising by hand on the lower surface of the collar part 43 formed by projecting sideways.

前記足型部10は、図3に示すように、踵を向ける側に踵側端部に向けて下り勾配αを有する傾斜部13を有する。前記傾斜部13の下り勾配αは例えば6〜26度、本形態では13度に形成されている。マッサージの際足型部10に載せた足は、傾斜部13上で踵側が低く支持される。その結果アキレス腱が引き伸ばされて脚部のストレッチ効果が付加されるため、健康増進効果が一層高まる点で好ましい。6度未満ではストレッチ効果があらわれず、26度を越えると立っているのが困難となる。なお傾斜部13は、その表面を円弧状に形成してもよい。   As shown in FIG. 3, the foot mold part 10 has an inclined part 13 having a downward slope α toward the heel side end part on the heel side. The downward slope α of the inclined portion 13 is, for example, 6 to 26 degrees, and is 13 degrees in this embodiment. The foot placed on the foot mold part 10 during the massage is supported on the inclined part 13 with a lower heel side. As a result, the Achilles tendon is stretched and a leg stretching effect is added, which is preferable in that the health promotion effect is further enhanced. If it is less than 6 degrees, the stretch effect does not appear, and if it exceeds 26 degrees, it becomes difficult to stand. In addition, you may form the inclined part 13 in the circular arc shape on the surface.

また前記足型部10は、その表面を厚さ数ミリ程度のマット体24で被覆される。該マット体24は、合成ゴム、エチレン酢ビ共重合樹脂(EVA)、熱可塑性エラストマーなどの弾性体を用いて形成されるため、足裏に対する触感を高めるとともに振動時の滑りを防止できる点で好ましい。またマット体24は、球面状の突起42が多数突設され、振動時足裏のツボを有効に刺激しうる点で好ましい。   The foot part 10 is covered with a mat body 24 having a thickness of several millimeters. Since the mat body 24 is formed using an elastic body such as synthetic rubber, ethylene vinyl acetate copolymer resin (EVA), or a thermoplastic elastomer, the mat body 24 can increase the feeling of touching the sole and prevent slipping during vibration. preferable. The mat body 24 is preferable in that a large number of spherical protrusions 42 are provided so as to effectively stimulate the pressure points on the soles during vibration.

前記駆動部4は、電動機Mと昇降手段5とを具える。前記電動機Mは本形態では、大トルクを得るためDCモータを用い、図2に示すように、前記基台2に図示されないボルトにより固定されている。なお本形態の電動機Mは、2170rpmの速度で回転する。   The drive unit 4 includes an electric motor M and an elevating means 5. In this embodiment, the electric motor M uses a DC motor to obtain a large torque, and is fixed to the base 2 with bolts (not shown) as shown in FIG. The electric motor M of this embodiment rotates at a speed of 2170 rpm.

前記昇降手段5は、足裏にマッサージ刺激を加える振動を発生するため載置者の体重負荷に抗して前記足載せ台3にを上下動させるものであり、前記電動機Mの回転運動を前記足載せ台3を上下動させる往復運動に変換する運動変換部25と前記体重負荷の一部を支える弾性支持部26とを含み構成される。   The raising / lowering means 5 moves the footrest 3 up and down against the weight load of the mounter in order to generate vibration that applies massage stimulation to the sole, and the rotational movement of the electric motor M is It includes a motion converting portion 25 that converts to a reciprocating motion that moves the footrest 3 up and down and an elastic support portion 26 that supports a part of the weight load.

前記運動変換部25は、前記電動機Mの回転速度を減速するベルト伝動部27と、回転運動を上下運動に変換して前記昇降板9を昇降させるクランク機構部34とを具える。前記ベルト伝道部27は図2、4に示すように、電動機Mの出力軸に取付けられた小プーリ28と、前記基台2に設けられた一対のボールベアリング軸受29、29により軸支された駆動軸30にキー溝31に嵌合されたキーにより相対回転不能に取付けられた前記小プーリ28よりも大径の大プーリ32と、双方のプーリ28、32間に掛け渡されたVベルト33とからなる。本形態では、ベルト伝道部27により前記電動機Mの出力が減速され、前記駆動軸30は450〜1700rpm程度、本形態では1130rpmの速度で回転する。   The motion conversion unit 25 includes a belt transmission unit 27 that decelerates the rotational speed of the electric motor M, and a crank mechanism unit 34 that converts the rotational motion into a vertical motion and moves the lift plate 9 up and down. As shown in FIGS. 2 and 4, the belt transmission portion 27 is pivotally supported by a small pulley 28 attached to the output shaft of the electric motor M and a pair of ball bearing bearings 29, 29 provided on the base 2. A large pulley 32 having a diameter larger than that of the small pulley 28 attached to the drive shaft 30 by a key fitted in a key groove 31 so as not to be relatively rotatable, and a V belt 33 stretched between the pulleys 28 and 32. It consists of. In this embodiment, the output of the electric motor M is decelerated by the belt transmission section 27, and the drive shaft 30 rotates at a speed of about 450 to 1700 rpm, in this embodiment, 1130 rpm.

前記クランク機構部34は、前記駆動軸30の両端部に形成され、該駆動軸30よりも小径でしかも中心軸C2が前記駆動軸30の中心軸C1に対して偏芯距離dだけ同方向へずれた一対の偏位軸35、35と、下端部を軸受36を介して偏位軸35に軸着するとともに上端部を支持軸P2により前記昇降板9の踵側の端部に枢着した一対の連結腕37、37とを含み構成されたものを例示している。   The crank mechanism portion 34 is formed at both ends of the drive shaft 30, has a smaller diameter than the drive shaft 30, and the central axis C 2 is in the same direction as the eccentric distance d with respect to the central axis C 1 of the drive shaft 30. A pair of displaced shafts 35, 35 and a lower end thereof are pivotally attached to the displacement shaft 35 via a bearing 36, and an upper end thereof is pivotally attached to the end of the elevating plate 9 on the heel side by a support shaft P2. An example including a pair of connecting arms 37 and 37 is illustrated.

前記クランク機構部34は前記駆動軸30の回転に連動して運動し、図5はその運動状態を線図で示すものである。図5の線図において、C1、C2間の線分は仮想のクランクを示し、C2、P2間の線分は連結腕37の中心線であり該連結腕37の動きを示し、P1、P2間の線分は前記昇降板9の中心線でありその動きを示す。図5(A)に示すように、駆動軸30の中心軸C1と偏位軸35の中心軸C2が同高さに並ぶとき昇降板9は水平に支持された中間点に位置する。駆動軸30の右回り(図面上の方向)の回転に連動して連結腕37が上昇し、これにより昇降板9のP2側(踵側)が押し上げられる。図5(B)に示すように、駆動軸30が90度回転して中心軸C2が中心軸C1の真上に至るとき昇降板9は中間点よりも前記偏芯距離d高い上死点まで上昇し、駆動軸30がさらに回転すると昇降板9は下降し、図5(C)に示すように、中間点に戻る。駆動軸30の回転により昇降板9のP2側は中間点よりも下位へと移動し、図5(C)に示すように、中心軸C2が中心軸C1の真下に位置するとき、昇降板9は中間点よりも前記偏芯距離d低い下死点に至り、これを過ぎると再び上昇して図5(A)に示す中間点に戻る。   The crank mechanism 34 moves in conjunction with the rotation of the drive shaft 30, and FIG. 5 is a diagram showing the movement state. In the diagram of FIG. 5, the line segment between C1 and C2 indicates a virtual crank, the line segment between C2 and P2 is the center line of the connecting arm 37 and indicates the movement of the connecting arm 37, and between P1 and P2 The line segment is the center line of the lifting plate 9 and shows its movement. As shown in FIG. 5A, when the center axis C1 of the drive shaft 30 and the center axis C2 of the displacement shaft 35 are arranged at the same height, the elevating plate 9 is positioned at an intermediate point supported horizontally. The connection arm 37 is raised in conjunction with the clockwise rotation (direction in the drawing) of the drive shaft 30, and thereby the P2 side (the heel side) of the lifting plate 9 is pushed up. As shown in FIG. 5B, when the drive shaft 30 rotates 90 degrees and the central axis C2 reaches directly above the central axis C1, the lifting plate 9 reaches the top dead center that is higher in the eccentric distance d than the intermediate point. Ascending and the drive shaft 30 further rotates, the elevating plate 9 descends and returns to the midpoint as shown in FIG. As the drive shaft 30 rotates, the P2 side of the lift plate 9 moves to a position lower than the intermediate point. As shown in FIG. 5C, when the center axis C2 is located directly below the center axis C1, the lift plate 9 Reaches a bottom dead center that is lower than the midpoint by the eccentric distance d, and after that, it rises again and returns to the midpoint shown in FIG.

前記昇降板9は、叙上の如くつま先側が支持枠12に支持軸P1により枢着されるとともに踵側がクランク機構部34で支持されるため、駆動軸30が1回転する毎に踵側が上下動を繰り返す。そして前記駆動軸30は450〜1700rpm程度の高速で回転するため昇降板9の上下動により振動が発生し、その結果足載せ台3に載せられる足裏にマッサージ効果を奏する刺激を与えることができる。   As described above, since the toe side is pivotally attached to the support frame 12 by the support shaft P1 and the heel side is supported by the crank mechanism portion 34 as described above, the heel side moves up and down every time the drive shaft 30 rotates. repeat. Since the drive shaft 30 rotates at a high speed of about 450 to 1700 rpm, vibration is generated by the vertical movement of the elevating plate 9, and as a result, a stimulus for exerting a massage effect can be given to the sole placed on the footrest 3. .

前記偏芯距離dは、例えば0.4〜1.8mm程度、本形態では、0.9mmに形成されている。偏芯距離dは、1.8mmを越えると足載せ台3の上下振幅が過大となるため、足裏への刺激が限度をオーバーしてマッサージ効果がむしろ低下するとともに振動音が大きくなり、0.4mm未満では足載せ台3の振幅が不足して充分なマッサージ効果が得られない。   The eccentric distance d is, for example, about 0.4 to 1.8 mm, and is 0.9 mm in this embodiment. When the eccentric distance d exceeds 1.8 mm, the vertical amplitude of the footrest 3 becomes excessive, so that the stimulation to the sole exceeds the limit, the massage effect is rather lowered, and the vibration noise increases. If it is less than 4 mm, the amplitude of the footrest 3 is insufficient and a sufficient massage effect cannot be obtained.

前記弾性支持部26は、図2、3に示すように、上下端部が前記昇降板9、前記基台2に各々取付けられ、昇降板9の踵側端部の両側部に配された一対のリンク体6、6と、該リンク体6に装着される引きバネ8とを含み構成されたものを例示している。   As shown in FIGS. 2 and 3, the elastic support portion 26 has a pair of upper and lower ends attached to the elevating plate 9 and the base 2, respectively, and arranged on both sides of the eaves side end portion of the elevating plate 9. The link bodies 6 and 6 and the tension spring 8 attached to the link body 6 are illustrated.

前記リンク体6は、本形態では、図3、6に示すように、下端部が前記基台2に下固定具38Lを介し支持軸P3にて枢着された一対の下リンク6L、6Lと、下端部が前記下リンク6Lの上端部にネジからなる枢支点7により枢支されるとともに上端部が前記昇降板9に上固定具38Uを介し支持軸P4にて枢着された一対の上リンク6U、6Uとからる。本形態の上リンク体6U、下リンク6Lは全て同じ長さに形成されるため、リンク体6は菱形をなす。なお前記下リンク6L、6Lは、上に向い開脚して配されるとともに、その下端部を間隔を隔てた異なる位置で基台2に枢着することもでき、また上リンク6U、6Uを上に向って巾狭に配するとともに、その上端部を間隔を隔てた異なる位置で昇降板9に枢着することもよい。また上リンク6Uと下リンク6Lとは、互いに異なる長さに形成してもよい。   In this embodiment, the link body 6 includes a pair of lower links 6L and 6L whose lower ends are pivotally attached to the base 2 via a lower fixing tool 38L via a support shaft P3, as shown in FIGS. The upper end of the lower link 6L is pivotally supported by a pivot point 7 made of a screw, and the upper end is pivotally attached to the lift plate 9 by the support shaft P4 via the upper fixture 38U. Links 6U and 6U are used. Since the upper link body 6U and the lower link 6L of this embodiment are all formed to have the same length, the link body 6 forms a rhombus. The lower links 6L and 6L are arranged with their legs open upward, and their lower ends can be pivotally attached to the base 2 at different positions spaced apart from each other. The upper links 6U and 6U can be attached to the lower links 6L and 6L. It may be arranged narrowly upward, and its upper end may be pivotally attached to the lifting plate 9 at different positions spaced apart from each other. Further, the upper link 6U and the lower link 6L may be formed to have different lengths.

前記リンク体6はパンタグラフ状をなすため、図6に示すように、前記昇降板9の上下動に連動して前記支持軸P3、P4間の間隔Hが増減し、同時に前記左右の枢支点7、7間の間隔Wが減少、増加する。そして前記引きバネ8は、間隔Wが増減するの左右の枢支点7、7間に張架され、図7に示すように、バネ力Fによりリンク体6を枢支点7、7間の距離を狭める向きに常に付勢している。その結果パンタグラフ状のリンク体6には、前記バネ力Fにより前記P3、P4間の間隔Hを増大する向きの力Pが発生し、該力Pにより昇降板9が押上げられる。その結果昇降板9にかかるマッサージを行う載置者の体重の一部が弾性支持部26で支持されて、昇降板9を上下動させる前記電動機Mの負荷が軽減されるため、一定のマッサージ振動をスムースに発生させることができるとともに小型の電動機Mを用いることが可能となる。   Since the link body 6 has a pantograph shape, as shown in FIG. 6, the distance H between the support shafts P3 and P4 increases or decreases in conjunction with the vertical movement of the elevating plate 9, and at the same time the left and right pivot points 7 , 7 is decreased and increased. The tension spring 8 is stretched between the left and right pivot points 7 and 7 where the interval W increases or decreases. As shown in FIG. Always energizing in a narrowing direction. As a result, the pantograph-like link body 6 generates a force P in the direction of increasing the distance H between the P3 and P4 by the spring force F, and the lifting plate 9 is pushed up by the force P. As a result, a part of the body weight of the mounter who massages the lifting plate 9 is supported by the elastic support portion 26, and the load of the motor M that moves the lifting plate 9 up and down is reduced. Can be generated smoothly and a small electric motor M can be used.

昇降板9が上昇することにより間隔Wが小さくなると、引きバネ8の長さが短くなるため前記リンク体6を付勢するバネ力Fは減少する。しかしながらリンク体6に作用する力のベクトル合成の結果、前記昇降板9を押し上げる力Pはむしろ昇降板9の上昇とともに増大する。これにより振動過程で足載せ台3が上昇することにより足型部10が足裏を深く押付けるタイミングに合わせてより強い力で足裏が押圧され、その結果足裏の末梢神経が有効に刺激されて活性化されるとともに血行の促進効果も大きくマッサージ効果が著しく向上する。また昇降板9の上昇時に電動機Mの負荷が軽減され回転速度がむしろ加速されるため、前記足型部10が足裏を深く押付けるタイミングでパルス的な加圧が生まれ、短時間の使用でも顕著なマッサージ効果を得ることができる。   When the interval W is reduced by raising the elevating plate 9, the length of the tension spring 8 is shortened, so that the spring force F for urging the link body 6 is reduced. However, as a result of the vector synthesis of the forces acting on the link body 6, the force P that pushes up the lift plate 9 increases rather as the lift plate 9 rises. As a result, the footrest 3 is raised during the vibration process, so that the sole is pressed with a stronger force in accordance with the timing when the foot 10 presses the sole deeply. As a result, the peripheral nerve of the sole is effectively stimulated. In addition to being activated, the effect of promoting blood circulation is great and the massage effect is remarkably improved. Further, since the load of the electric motor M is reduced and the rotational speed is rather accelerated when the elevating plate 9 is raised, pulse-like pressurization is generated at the timing when the foot mold part 10 presses the sole of the foot deeply. A remarkable massage effect can be obtained.

本形態のマッサージ器1は、トランス、整流器、タイマーなどを含む制御部39により動作がコントロールされる。前記制御部39は、図示されない電気コードにより家庭用100V電源に接続され、前記電動機Mを駆動している。該制御部39でコントロールされたマッサージ器1は、図9に示すように、スイッチON信号を受け電動機Mに給電することにより振動が作動してマッサージを開始する。そして設定時間経過によるタイマー作動、又はスイッチOFF信号を受け、電動機Mへの給電を停止することにより振動が停止してマッサージを終了する。   The operation of the massage device 1 of this embodiment is controlled by a control unit 39 including a transformer, a rectifier, a timer, and the like. The control unit 39 is connected to a household 100V power source by an electric cord (not shown) and drives the electric motor M. As shown in FIG. 9, the massage device 1 controlled by the control unit 39 receives the switch ON signal and supplies power to the electric motor M to start the massage. Then, upon receiving the timer operation or the switch OFF signal when the set time elapses, the power supply to the electric motor M is stopped to stop the vibration and the massage is finished.

前記スイッチ信号を送るスイッチ操作部14は、前記基台2のつま先側に立設された柱状部40の上端部に設けられ、カバー体11の足型部10、10間に設けられた弾性キャップ41の内部に配置される。前記スイッチ操作部14は、足型部10、10間に配されるため足型部10に載置した足で容易に入切でき、操作性に優れる点で好ましい。   The switch operation part 14 for sending the switch signal is provided at the upper end of the columnar part 40 erected on the toe side of the base 2 and is provided between the foot mold parts 10 and 10 of the cover body 11. 41 is disposed inside. Since the switch operation unit 14 is arranged between the foot mold parts 10 and 10, it can be easily turned on and off with a foot placed on the foot mold part 10, and is preferable in terms of excellent operability.

偏芯距離dを1mmとして上死点と下死点との間隔が2mmに形成されたクランク機構部34により上下に駆動される昇降板9と基台2の間に、表1に示す条件に基づいて形成され図6に示される弾性支持部26を取付けた実施例を作成した。本実施例のリンク体6は昇降板9の上下動に連動して、支持軸P3、P4間の距離であるリンク高さHが中間点での29mmを中心に、上死点での30mmと下死点での28mmの間で増減する変形を繰返す。リンク体6の枢支点7間に張架された前記引きバネ8は前記変形により伸縮し、そのバネ力Fに基づいてリンク体6が昇降板9を押上げる。   Table 1 shows the conditions shown in Table 1 between the lift plate 9 and the base 2 that are driven up and down by a crank mechanism 34 having an eccentric distance d of 1 mm and a distance between the top dead center and the bottom dead center of 2 mm. An embodiment was made with the elastic support 26 formed thereon and shown in FIG. In the link body 6 of this embodiment, the link height H, which is the distance between the support shafts P3 and P4, is 30 mm at the top dead center centered on 29 mm at the middle point in conjunction with the vertical movement of the lifting plate 9. Repeat the deformation to increase or decrease between 28mm at the bottom dead center. The pull spring 8 stretched between the pivot points 7 of the link body 6 expands and contracts due to the deformation, and the link body 6 pushes up the lifting plate 9 based on the spring force F.

前記実施例において、上死点、下死点及び中間点で弾性支持部26が昇降板9を押上げる力Pをシミュレーションにより求めた。その結果図8に示すように、下死点は49.82N、中間点で50.98N、上死点で52.09Nの力Pがシミュレーションされ、前記昇降板9を押上げる力Pは昇降板9が上昇するに従い漸増することが確認できた。   In the said Example, the force P which the elastic support part 26 pushes up the raising / lowering board 9 in the top dead center, the bottom dead center, and the intermediate point was calculated | required by simulation. As a result, as shown in FIG. 8, a force P of 49.82N at the bottom dead center, 50.98N at the middle point, and 52.09N at the top dead center is simulated, and the force P pushing up the lift plate 9 is the lift plate. It was confirmed that 9 gradually increased as 9 increased.
