Description

本発明は、使用者の脚部の運動を促したり脚部の運動を矯正したりするための運動補助装置に関するものである。   The present invention relates to an exercise assisting device for urging a user's leg movement or correcting the leg movement.

脚部の運動を補助する装置として、種々のものが提案されている。リハビリテーションという観点からは、使用者が自発的に筋力を発揮するのではなく、使用者の身体に外力を与えることで使用者の筋群に伸縮を行わせる他動運動によって運動効果を得る運動補助装置が知られている。   Various devices have been proposed for assisting leg movement. From the viewpoint of rehabilitation, exercise assistance that obtains an exercise effect by passive movement that causes the user's muscle group to expand and contract by giving external force to the user's body, rather than spontaneously exerting muscle strength by the user The device is known.

このような運動補助装置において、脚部を対象とし且つ使用者が立位で使用するものとしては、左右の足をそれぞれ載せる一対のステップに底背屈方向の動作を行わせるとともに上記ステップを前後方向に往復駆動することで、ステップが歩行運動を模擬した動きを行うものとし、この左右のステップに足を載せている使用者は、歩行動作を他動運動として行うことになるものが知られている（たとえば、特許文献１参照）。   In such an exercise assisting device, the leg portion is intended for use by the user in a standing position, and a pair of steps on which the left and right feet are respectively placed are operated in the dorsiflexion direction, and the above steps are performed back and forth.

(For example, refer to Patent Document 1).

国際公開２００８／０４１５５４International Publication 2008/041554

上記のものは、足関節の可動域を広げることや、歩行に伴って使用することになる下腿部の筋群を刺激するという点において、きわめて有効である。   The above is extremely effective in expanding the range of motion of the ankle joint and stimulating the muscles of the lower leg that will be used with walking.

一方、歩行訓練を行う場合、殊にリハビリテーション目的の歩行訓練を行う場合、関節可動域の拡大や下腿部の筋群の訓練に加えて、踏み出しに際しての重心移動も重要となる。   On the other hand, when performing gait training, particularly when performing gait training for the purpose of rehabilitation, in addition to expanding the range of motion of the joint and training the muscles of the lower leg, it is also important to move the center of gravity when stepping on.

つまりは歩行時の足の踏み出しは、身体の前後左右のバランスをいったん崩すことでなされるものであり、上記バランスを崩すための体幹移動を恐怖感なく行うことができるようにならなければ、歩行動作はぎこちないものとなる。   In other words, the stepping of the foot during walking is done by breaking the balance of the front, back, left and right of the body once, and if the trunk movement to break the balance can not be done without fear, Walking motion is awkward.

本発明はこのような点に鑑みなされたものであって、足の底背屈動作に加えて体重を左右や前後に移す重心移動（体幹移動）を併せて訓練することができる運動補助装置を提供することを課題とするものである。   This invention is made in view of such a point, Comprising: In addition to the plantar dorsiflexion operation | movement, the exercise | movement assistance apparatus which can be trained together with the gravity center movement (trunk movement) which moves a weight to the left and right or the front and back It is a problem to provide.

本発明は、架台と、架台に設けられ底背屈方向に動作する左右一対の足置用のステップと、上記架台を支える基台とからなり、上記架台は基台に対して、水平方向または水平軸周りの回転方向に可動となるように支持されていることに特徴を有している。   The present invention comprises a gantry, a pair of left and right footrests that are provided on the gantry and operate in the dorsiflexion direction, and a base that supports the gantry. It is characterized by being supported so as to be movable in the direction of rotation around the horizontal axis.

足置用の左右のステップはその底背屈方向動作に前後方向の水平成分をもつ動作をするものであり、架台は上記基台に対して左右の水平方向動作を含む動きを行うものであることが好ましく、更には上記架台は、上記ステップの動作に同期した水平方向動作または水平軸周りの回転動作を行うものであることが好ましい。   The left and right steps for foot placement are those that have a horizontal component in the front-rear direction in the movement in the dorsiflexion direction, and the gantry performs a movement including left and right horizontal movements relative to the base. Further, it is preferable that the gantry performs a horizontal operation synchronized with the operation of the step or a rotation operation around a horizontal axis.

上記ステップの動作と上記架台の動作の少なくとも一方を担う駆動源を備えていることも好ましい。   It is also preferable that a drive source responsible for at least one of the operation of the step and the operation of the gantry is provided.

本発明においては、底背屈動作を行うステップが設けられた架台が基台に対して水平方向または水平軸周りの回転方向に可動となるように支持されているために、足の底背屈動作に加えて、前後あるいは左右の体幹移動や体幹の傾きを行わせることができるものであり、歩行動作の訓練としてより好ましいものとなっている。   In the present invention, since the gantry provided with the step for performing the sole dorsiflexion operation is supported so as to be movable in the horizontal direction or the rotational direction around the horizontal axis with respect to the base, In addition to the movement, the trunk can be moved forward and backward or left and right, and the trunk can be tilted, which is more preferable as a walking movement training.

特に足置用の左右のステップがその底背屈方向動作に前後方向の水平成分をもつ動作を行い、架台は上記基台に対して左右の水平方向動作を含む動きを行うものであると、前後方向と左右方向の体幹移動を共に行うことができるために、歩行動作の訓練に更に好ましい結果を得ることができる。   In particular, the left and right steps for footrest perform an operation having a horizontal component in the front-rear direction in the dorsiflexion direction motion, and the gantry performs a motion including the left and right horizontal motion with respect to the base. Since both trunk movements in the front-rear direction and the left-right direction can be performed, a more favorable result can be obtained for training of walking motion.

また上記架台が、上記ステップの動作に同期した水平方向動作または水平軸周りの回転動作を行うものであると、足の底背屈動作と体幹の移動方向とを関連づけて行うことができるために、歩行の訓練において特に好ましい結果を得ることができる。   In addition, if the gantry performs a horizontal movement synchronized with the movement of the step or a rotation movement around the horizontal axis, the dorsiflexion movement of the foot and the movement direction of the trunk can be associated with each other. In particular, a particularly favorable result can be obtained in walking training.

上記ステップの動作と上記架台の動作の少なくとも一方を担う駆動源を備えたものとすれば、いわゆる他動運動として歩行訓練を行うことができるために、自発的な動きが困難な場合においても、有効な運動を行わせることができる。   Assuming that a drive source responsible for at least one of the operation of the step and the operation of the gantry is provided, walking training can be performed as a so-called passive motion, so even when it is difficult to move spontaneously, Effective exercise can be performed.

本発明を実施の形態の一例に基づいて詳述すると、この運動補助装置は、上面に左右一対のステップ３，３が配されている架台２と、上記架台２内に配設されて上記ステップ３，３の駆動を担う駆動手段４と、架台２を支えている基台１とからなる。   The present invention will be described in detail based on an example of the embodiment. This exercise assisting device includes a gantry 2 in which a pair of left and right steps 3 and 3 are arranged on an upper surface, and the step 2 disposed in the gantry 2. The driving means 4 for driving the motors 3 and 3 and the base 1 supporting the gantry 2 are provided.

上記ステップ３，３は、使用者の足裏全体を載せることができる寸法のもので、各ステップ３の後端寄りの部分が架台２上に設けた支柱２１に配したほぼ左右方向の軸３０によって支持されて夫々上下に回動自在となっているとともに、各ステップ３の前端側が上記駆動手段４に連結されており、各ステップ３，３は駆動手段４によって上下に回動駆動される。   Steps 3 and 3 are sized so that the entire sole of the user can be placed thereon, and a portion near the rear end of each step 3 is a substantially horizontal shaft 30 disposed on a column 21 provided on the gantry 2. The front end side of each step 3 is connected to the driving means 4, and each step 3, 3 is rotated up and down by the driving means 4.

上記駆動手段４は、架台２上に配されたモータ４０と、該モータ４０の回転がピニオン４１を介して伝達されるギア４２と、ギア４２の周部に各一端が連結され且つ他端が各ステップ３，３に連結された連接棒４３とからなるもので、一方の連接棒４３とギア４２との連結点は、他方の連接棒４３とギア４２との連結点からギア４２の軸回りにおいてほぼ１８０°ずれたところにあるために、モータ４０によるギア４２の回転に伴い、両ステップ３，３はほぼ１８０°ずれた位相で上下に回動する。   The driving means 4 includes a motor 40 disposed on the gantry 2, a gear 42 to which rotation of the motor 40 is transmitted via a pinion 41, one end connected to a peripheral portion of the gear 42, and the other end The connecting rod 43 is connected to each of the steps 3 and 3. The connecting point between one connecting rod 43 and the gear 42 is around the axis of the gear 42 from the connecting point between the other connecting rod 43 and the gear 42. Therefore, as the gear 42 is rotated by the motor 40, the steps 3 and 3 are rotated up and down with a phase shifted by approximately 180 °.

このために、ステップ３，３に使用者が足を載せて立っている時、ステップ３，３の上記回動に伴い、使用者は足のつま先側を下げる底屈(plantar flexion)動作と、つま先側を上げる背屈(dorsi flexion)動作とを繰り返し行うことになる。また、左足が底屈を行う時、右足が背屈を、左足が背屈を行う時、右足が底屈を行う。   For this reason, when the user stands on the steps 3 and 3, with the rotation of the steps 3 and 3, the user performs a plantar flexion operation to lower the toe side of the foot, and The dorsi flexion movement to raise the toe side is repeated. Also, when the left foot is bent, the right foot is dorsiflexed, and when the left foot is dorsiflexed, the right foot is bent.

なお、両ステップ３，３は平行ではなく、ステップ３，３に足を載せた時、つま先側が外側に少し開くように設けられており、この関係で、連接棒４３とギア４２との連結点及び連接棒４３とステップ３との連結点は、夫々自在継手で形成してある。   In addition, both steps 3 and 3 are not parallel, and when the foot is placed on steps 3 and 3, the toe side is provided so that it slightly opens outward. In this relationship, the connecting point between the connecting rod 43 and the gear 42 is provided. And the connection point of the connecting rod 43 and step 3 is formed with a universal joint, respectively.

そして、上記左右一対のステップ３，３や駆動手段４が設置されている上記架台２は、基台１上の支柱１０に設けた前後方向の回転軸２０によって、左右方向中央部が支持されることで、左右方向に回動自在となっている。   The gantry 2 in which the pair of left and right steps 3 and 3 and the driving means 4 are installed is supported at the center in the left and right direction by a front and rear rotating shaft 20 provided on the column 10 on the base 1. Thus, it can be freely rotated in the left-right direction.

このために、上記ステップ３，３に左右の足を載せて立ち、この状態で上記駆動手段４を作動させてステップ３，３を動かすことで、使用者の脚部に対して他動運動を行わせる時、使用者は架台２の左右回動に伴って左右に体幹を傾かせることになる。   For this purpose, the left and right feet are placed on the steps 3 and 3 and the driving means 4 is operated in this state to move the steps 3 and 3, thereby performing a passive movement with respect to the legs of the user. When performing, the user tilts the trunk to the left and right as the gantry 2 rotates left and right.

すなわち、ステップ３，３に使用者が両足を載せた状態で、一方の足を底屈、他方の足を背屈させると、通常、底屈させた足の方に重心が移るために、左右のバランスが変化し、架台２は回転軸２０を中心に重心が移った方の足側が下がり、他方が上がる。   In other words, when the user puts both feet in Steps 3 and 3, when one leg is bent to the bottom and the other leg is bent to the back, the center of gravity usually shifts toward the bent leg. The balance of the gantry 2 is lowered on the foot side where the center of gravity has moved around the rotation axis 20 and the other is raised.

駆動機構４によるステップ３，３の回動で、底屈させる側と背屈させる側とが入れ替われば、使用者の左右の重心移動で架台２は逆方向に傾く。使用者の足に底屈と背屈とを交互に行わせることができるとともに、この時に生じる使用者の重心の左右移動を利用して、使用者の体幹を左右交互に傾かせることができるものである。   If the bottom bending side and the back bending side are interchanged by the rotation of steps 3 and 3 by the drive mechanism 4, the gantry 2 tilts in the opposite direction due to the left and right center of gravity movement of the user. The user's feet can be alternately bent and bent back, and the user's trunk can be tilted alternately left and right using the left / right movement of the user's center of gravity. Is.

なお、架台２の左右両端と基台１との間には弾性体５，５を配置することで、架台２の左右の傾きがステップ３，３の回動駆動に応じた緩慢な速度で行われるようにしてある。弾性体５は使用者の体重に応じてばね力を調節することができるものが好ましい。弾性体５に代えてダンパーを用いてもよいのはもちろんである。また、架台２を支えることになる支柱１０は、強度の点からすれば、図１及び図２に示すような架台２の前後端に配したものではなく、架台２の左右方向中央部の前後方向全長にわたり支える形態のものが好ましい。   The elastic bodies 5 and 5 are arranged between the left and right ends of the gantry 2 and the base 1, so that the left and right inclinations of the gantry 2 are performed at a slow speed according to the rotational driving of the steps 3 and 3. It is supposed to be. The elastic body 5 is preferably one that can adjust the spring force according to the weight of the user. Of course, a damper may be used instead of the elastic body 5. Moreover, the column 10 that supports the gantry 2 is not arranged at the front and rear ends of the gantry 2 as shown in FIG. 1 and FIG. A configuration that supports the entire length in the direction is preferable.

ところで、使用者によっては、底屈させた足側に重心を移動させる動作が困難であったりする場合がある。この点からすれば、架台２の左右方向の揺動（シーソー動）も、動力で行うものとしてもよい。図４はこの場合の一例を示しており、前記駆動手段４におけるピニオン４１と噛み合うドリブンギア４５を設けるとともに、ドリブンギア４５の周部と架台２における回転軸２０から離れた部分とを連接棒４６で連結してある。なお、ステップ３の駆動のためのギア４２と、架台２の駆動のためのドリブンギア４３とは等速で１回転するものとして、右足を載せたステップ３が右足を底屈させる時、架台２の右側（右足が載った側）を下げ、左足を載せたステップ３が左足を底屈させる時、架台２の左側（左足が載った側）を下げるようにしている。   By the way, depending on the user, it may be difficult to move the center of gravity to the bent side of the foot. From this point, the horizontal swing (seesaw motion) of the gantry 2 may be performed by power. FIG. 4 shows an example of this case. A driven gear 45 that meshes with the pinion 41 in the driving means 4 is provided, and the connecting rod 46 connects the peripheral portion of the driven gear 45 and the portion of the gantry 2 away from the rotary shaft 20. It is connected with. Note that the gear 42 for driving the step 3 and the driven gear 43 for driving the gantry 2 are rotated at a constant speed, and when the step 3 with the right foot is bent to the right foot, the gantry 2 The right side (the side on which the right foot is placed) is lowered, and when the step 3 on which the left foot is placed causes the left foot to bend, the left side (the side on which the left foot is placed) is lowered.

上記ドリブンギア４５は架台２上に配置するが、支柱１０側に設けてもよい。ただし、ドリブンギア４５とピニオン４１との噛み合いが架台２が傾いても保たれるものとしておく。   The driven gear 45 is arranged on the gantry 2 but may be provided on the support column 10 side. However, it is assumed that the engagement between the driven gear 45 and the pinion 41 is maintained even when the gantry 2 is tilted.

このように架台２の動きも動力で行う時、左右の足の底屈背屈動作と、体幹を左右に傾ける動作とを確実に同期させることができ、安定したリズミカルな動きを使用者に行わせることができる。   Thus, when the movement of the gantry 2 is also performed with power, it is possible to reliably synchronize the plantar flexion and dorsiflexion movements of the left and right feet and the movement of tilting the trunk to the left and right, and to provide a stable rhythmic movement to the user. Can be done.

動力による駆動は架台２側だけとし、足を底背屈させるステップ３の回動は、架台２の傾きによる使用者の重心移動によってなされるようにしてもよい。図５はこの場合の一例を示しており、図４に示したものとほぼ同じ構成であるが、ステップ３，３に連接棒４３，４３で連結されたギア４２をピニオン４１と噛み合わずに自由回転するものとしてある。なお、この例におけるギア４２の回転には常に抵抗が加わるようにしておくことが好ましい。   Driving by power may be performed only on the gantry 2 side, and the rotation of step 3 that causes the foot to bend back may be performed by moving the center of gravity of the user due to the tilt of the gantry 2. FIG. 5 shows an example of this case, and the configuration is almost the same as that shown in FIG. 4, but the gear 42 connected to the steps 3 and 3 by the connecting rods 43 and 43 can be freely engaged with the pinion 41. It is supposed to rotate. In addition, it is preferable to always add resistance to the rotation of the gear 42 in this example.

駆動手段４による駆動で架台２の右側が下がる時、両ステップ３，３に足を載せている使用者は右足側に重心を移動させることになるが、架台２の右足側が下がっていることもあって、使用者は右足のつま先を底屈させることで、つまりは右足のつま先側に重心をかけることで安定を保とうとする。架台２の左右の傾きが変われば、逆に左足のつま先側に重心をかけて安定を保とうとする。このために、架台２の左右揺動に伴い、使用者は左右の足に底屈と背屈とを行わせることになる。   When the right side of the gantry 2 is lowered by driving by the driving means 4, the user who puts his / her feet on both steps 3 and 3 moves the center of gravity to the right foot side, but the right foot side of the gantry 2 may be lowered. Therefore, the user tries to maintain stability by bending the toe of the right foot to the bottom, that is, by placing the center of gravity on the toe side of the right foot. If the left / right inclination of the gantry 2 changes, the center of gravity of the left foot is placed on the toe side to maintain stability. For this reason, as the gantry 2 swings left and right, the user causes the left and right feet to perform bottom flexion and dorsiflexion.

図６に他例を示す。基本的構成は図４に示したものとほぼ同じで、駆動手段４によってステップ３，３の駆動を行うと同時に、ピニオン４１の回転がドリブンギア４６を介して伝達されるギア４７の偏心部と架台２とが連接棒４６で連結されている。なお、架台２上のドリブンギア４６から基台１上のギア４７には架台２が左右回動しても動力が伝達されるものとしておく。   FIG. 6 shows another example. The basic configuration is substantially the same as that shown in FIG. 4, and the driving means 4 drives the steps 3 and 3, and at the same time the eccentric portion of the gear 47 to which the rotation of the pinion 41 is transmitted via the driven gear 46. The gantry 2 is connected by a connecting rod 46. Note that power is transmitted from the driven gear 46 on the gantry 2 to the gear 47 on the gantry 1 even if the gantry 2 rotates left and right.

ステップ３の動きに同期させた左右揺動を架台２に行わせることができるものであり、また、ここでは架台２側から支柱２２を下方に突出させて支柱２２の下端を回転軸１２によって基台１に連結して架台２を左右回転自在に支持して、架台２を回転自在とする回転軸１２が架台２から下方に離れた位置に設けているために、回転軸１２を中心とした架台２の左右揺動は、先に示した実施例のものよりも左右方向の移動量が大きくなる。このために使用者の体幹の左右移動量を大きくすることができる。   The gantry 2 can be made to swing left and right in synchronism with the movement of step 3, and here, the column 22 protrudes downward from the gantry 2 side and the lower end of the column 22 is supported by the rotating shaft 12. Since the rotary shaft 12 that is connected to the base 1 and supports the base 2 so as to be rotatable left and right, and that allows the base 2 to rotate freely, is provided at a position separated downward from the base 2, the rotational axis 12 is the center. The horizontal swing of the gantry 2 has a larger amount of movement in the left-right direction than that of the above-described embodiment. For this reason, the left-right movement amount of the user's trunk can be increased.

図８に示すものは、図７に示したものに更にステップ３，３の前後動が加わるようにしたもので、ステップ３から突出させたアーム３３の先端を支柱２１に回転軸３０で取り付けている。回転軸３０を中心にステップ３が回動する時、ステップ３は前後にも移動する。このステップ３の前後動は、つま先側が下がる時、前方に移動し、つま先側が上がる時、後方に移動する。歩行にとって重要な左右の体幹移動と前後の体幹移動の双方を行わせることができるものである。   FIG. 8 shows a configuration in which the forward and backward movements of steps 3 and 3 are added to the configuration shown in FIG. 7, and the tip of the arm 33 projected from step 3 is attached to the column 21 with the rotary shaft 30. Yes. When step 3 rotates about the rotation shaft 30, step 3 also moves back and forth. The forward / backward movement of Step 3 moves forward when the toe side is lowered, and moves backward when the toe side is raised. Both the left and right trunk movements important for walking and the front and rear trunk movements can be performed.

なお、架台２の左右の動きと、ステップ３の前後の動きとは同期して行われるものであり、また、前述のように架台２はつま先側が下がるステップ３が設けられている側が下がりつつ基台１の左右方向中心から離れる方向に移動するようにしていることから、架台２の左右の動きとステップ３の前後の動きとの合成は、図８(a)に示すように、Ｖ字形の軌道となる。   The left and right movements of the gantry 2 and the movements before and after the step 3 are performed in synchronization. As described above, the gantry 2 is lowered while the side on which the step 3 where the toe side is lowered is provided is lowered. Since it moves in the direction away from the center of the horizontal direction of the table 1, the combination of the horizontal movement of the gantry 2 and the movement before and after the step 3 is V-shaped as shown in FIG. Orbit.

しかし、ギア４７における連接棒４６の連結点が１８０°異なっておれば、架台２はつま先側が上がるステップ３が設けられている側が下がりつつ基台１の左右方向中心から離れる方向に移動することになり、架台２の左右の動きとステップ３の前後の動きとの合成が、図８(b)に示すように、ハ字形の軌道となる。このために、ギア４７における上記連結棒４６の連結点を１８０°異なる位置に変更できるようにしておけば、図８(a)(b)に示す２つの動きを選択的に行わせることができることになる。ちなみに図８(a)に示す動きは、歩行の蹴り出しや接地の動作を模擬するものとなり、図８(b)に示す動きは、スケートでの蹴り出し様のトレーニングとなる。   However, if the connecting point of the connecting rod 46 in the gear 47 is different by 180 °, the gantry 2 moves in a direction away from the center in the left-right direction of the base 1 while the side where the step 3 is raised is lowered. Thus, the combination of the left and right movements of the gantry 2 and the movements before and after the step 3 forms a C-shaped trajectory as shown in FIG. For this reason, if the connecting point of the connecting rod 46 in the gear 47 can be changed to a position different by 180 °, the two movements shown in FIGS. 8A and 8B can be selectively performed. become. Incidentally, the movement shown in FIG. 8 (a) simulates the kicking and grounding movements of walking, and the movement shown in FIG. 8 (b) is a kick-like training in skating.

図９に別の実施例を示す。架台２とステップ３及び駆動手段４におけるステップ３の駆動部分については図７に示したものと同じである。しかし、基台１に対して架台２はリニアガイド６によって左右にスライド自在に配してある。また、基台１の左右に夫々配したリニアガイド６は、左側と右側が共に外側方が下がる勾配を持つものとしてある。   FIG. 9 shows another embodiment. The drive part of step 3 in the gantry 2 and step 3 and the drive means 4 is the same as that shown in FIG. However, the gantry 2 is arranged to be slidable left and right by the linear guide 6 with respect to the base 1. In addition, the linear guides 6 respectively arranged on the left and right sides of the base 1 are assumed to have a gradient in which the left side and the right side both fall outward.

左右のステップ３，３に載せた足のうちの一方に重心を移せば、左右のリニアガイド６のうちの上記重心に近い側のリニアスライド６には、上記勾配のために架台２を外側方へスライドさせる力が発生し、架台２はその方向に移動する。逆の足に重心を移せば、架台２も逆方向にスライドする。   If the center of gravity is moved to one of the feet placed on the left and right steps 3 and 3, the linear slide 6 on the side closer to the center of gravity of the left and right linear guides 6 has the gantry 2 outside due to the above gradient. Is generated, and the gantry 2 moves in that direction. If the center of gravity is moved to the opposite foot, the gantry 2 also slides in the opposite direction.

左右のステップ３，３に回動を（本例ではステップ３の前後動も）行わせたことでステップ３上に立つ使用者の重心移動が起これば、架台２の左右移動もなされるものである。この左右移動に際し、図中の弾性体５は、架台２を基台１の左右方向中央に保つように働く。弾性体５は必須のものではなく、無くてもよい。   If the center of gravity of the user standing on step 3 is moved by rotating the left and right steps 3 and 3 (in this example, the back and forth movement of step 3), the pedestal 2 is also moved left and right It is. During the left-right movement, the elastic body 5 in the drawing works to keep the gantry 2 at the center in the left-right direction of the base 1. The elastic body 5 is not essential and may be omitted.

なお、本例では架台２がスライド動作に伴ってわずかに傾くものであり、この傾きを許すために、リニアガイド６における架台２との連結は回転軸６０を介して行っている。リニアガイド６に代えて、図９(c)に示すように、傾斜面６１をローラ６２が転動する構成としてもよい。   In this example, the gantry 2 is slightly tilted with the sliding operation, and the linear guide 6 is connected to the gantry 2 via the rotating shaft 60 in order to allow the tilt. Instead of the linear guide 6, as shown in FIG. 9 (c), the inclined surface 61 may be configured so that the roller 62 rolls.

図１０は架台２の水平スライド移動を駆動手段４によって行うようにしたものを示している。駆動手段４のピニオン４１の回転は、ギア４２を介してステップ３，３を駆動するほか、ドリブンギア４５及びギア４７と連接棒４６を介して架台２を左右に水平スライド移動させる。左右スライド移動に伴って架台２が傾きを持つようにするために、リニアガイド６を図９に示す傾きを持つものとしてもよい。リニアガイド６に代えてローラを用いてもよいのも同様である。   FIG. 10 shows a state in which the horizontal slide movement of the gantry 2 is performed by the driving means 4. The rotation of the pinion 41 of the driving means 4 not only drives the steps 3 and 3 via the gear 42 but also horizontally slides the gantry 2 left and right via the driven gear 45 and the gear 47 and the connecting rod 46. The linear guide 6 may have an inclination shown in FIG. 9 so that the gantry 2 has an inclination in accordance with the left / right sliding movement. Similarly, a roller may be used instead of the linear guide 6.

架台２が左右に移動したり左右方向に傾くものを示したが、このほか、図１１及び図１２に示すように、架台２の中央１点を球ジョイント８で受けることにより、前後左右に架台２が傾くようにしてもよい。架台２は、使用者２の重心が球ジョイント８から見てどちらにあるかによって傾く方向を変化させるものであり、このために使用者は足の底背屈動作に加えて、重心がどの位置にあるかを架台２の傾き方向から容易に認識することができ、前後左右方向への重心のかけ方の訓練に好適に用いることができる。   Although the pedestal 2 moves left and right or tilts in the left-right direction, as shown in FIGS. 11 and 12, the pedestal 2 receives a central point by a ball joint 8 so 2 may be inclined. The gantry 2 changes the tilting direction depending on where the center of gravity of the user 2 is seen from the ball joint 8. For this purpose, the user can determine the position of the center of gravity in addition to the sole dorsiflexion motion. Can be easily recognized from the tilt direction of the gantry 2 and can be suitably used for training how to apply the center of gravity in the front-rear and left-right directions.

架台２に前後左右の自在な傾きを許す構成は、球ジョイント８ではなく、図１３に示すように、基台１と架台２との間の空間全体にフォーム材からなる弾性体５を配置することによっても得ることができる。コイルばねなどからなる弾性体５を上記空間に並べるようにしてもよい。図中５０は基台１の下面に配した弾性材であり、接地面に凹凸があっても安定させることができる。   The structure that allows the gantry 2 to freely tilt in the front, rear, left, and right is not the ball joint 8 but the elastic body 5 made of foam material is disposed in the entire space between the base 1 and the gantry 2 as shown in FIG. Can also be obtained. You may make it arrange the elastic body 5 which consists of a coil spring etc. in the said space. In the figure, reference numeral 50 denotes an elastic material disposed on the lower surface of the base 1 and can be stabilized even if the grounding surface has irregularities.

ステップ３の駆動に加えて架台２もモータ４０にて駆動する場合、上述の例では両者を同期させているが、この同期は位相を少しずらせておいてもよい。また、架台２が１往復する間にステップ３が２往復するようにしてもよく、ステップ３の動きと架台２の動きとは上記の例で示したものに限定されるものではない。   In the case where the gantry 2 is also driven by the motor 40 in addition to the driving in Step 3, the two are synchronized in the above example, but this synchronization may be slightly shifted in phase. Further, step 3 may be reciprocated twice while the gantry 2 reciprocates once, and the movement of step 3 and the movement of the gantry 2 are not limited to those shown in the above example.

ドリブンギア４５やギア４７等のギア類で且つ回転軸方向を変換しているものは、たとえばベベルギアなどで形成されるのであるが、図ではこの点を反映させていない。またギア４７に一端を連結した連接棒４６の他端を基台１に連結する場合は、ギア４７を架台２側に配置することができることから、どのように駆動するかについても上記実施例に限定されるものではない。   The gears such as the driven gear 45 and the gear 47 whose rotational axis direction is converted are formed by, for example, bevel gears, but this point is not reflected in the drawing. Further, when the other end of the connecting rod 46 having one end connected to the gear 47 is connected to the base 1, the gear 47 can be arranged on the gantry 2 side. It is not limited.
