　従来から、飛行機内等で長時間同じ姿勢を取り続けることに伴って血液の流れが悪くなり、下肢などの静脈において血栓が生じる、エコノミークラス症候群と呼ばれる静脈血栓塞栓症が良く知られている。この血栓の発生を予防するために、足首を運動させる装置が用いられている。特許文献１は、この種の装置を開示する。 Conventionally, venous thromboembolism called economy class syndrome, in which blood flow deteriorates as a result of taking the same posture for a long time in an airplane or the like and a thrombus occurs in a vein such as a lower limb, is well known. In order to prevent the occurrence of this thrombus, a device that moves the ankle is used. Patent Document 1 discloses this type of apparatus.
　特許文献１は、乗物用のシートのフットレストを、踵に相当する位置を支点として、電動モータ等により回動させることで、着座者の足を運動させる装置を開示する。特許文献１に記載されたこのフットレストは着座者が座っているシートと一体型であるか、又は、前席のシートと一体型であることが記載されている。 Patent Document 1 discloses an apparatus for moving a foot of a seated person by rotating a footrest of a vehicle seat by an electric motor or the like with a position corresponding to a heel as a fulcrum. It is described that this footrest described in Patent Document 1 is integrated with a seat on which a seated person is sitting, or integrated with a front seat.

　しかし、上記特許文献１の構成は、踵に相当する位置を支点として、足を回転（上下）運動させているため、足首の屈伸運動ができる幅が狭い範囲に限られている。そして、特許文献１の装置は、乗物のシートと一体型になっているので、他の場所（例えば自宅又は職場など）で使用することができない。更に、特許文献１の装置の駆動メカニズムは電動モータ等しか記載されていないため、省エネルギー性の観点からも改善の余地があった。 However, the configuration of Patent Document 1 described above is limited to a narrow range in which the ankle can bend and extend because the foot is rotated (up and down) with the position corresponding to the heel as a fulcrum. And since the apparatus of patent document 1 is united with the vehicle seat, it cannot be used in other places (for example, a home or a workplace). Furthermore, since only the electric motor or the like is described as the drive mechanism of the device of Patent Document 1, there is room for improvement from the viewpoint of energy saving.
　本発明は以上の事情に鑑みてされたものであり、その目的は、足首を十分に屈伸させ、様々な場所で使用可能であるとともに、省電力を実現可能な足首運動装置を提供することにある。 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an ankle exercise device that can sufficiently bend and stretch the ankle, can be used in various places, and can realize power saving. is there.

It is a perspective view which shows the main structures of the ankle exercise device 1 which concerns on one Embodiment of this invention. FIG. 2 is a plan view schematically illustrating a configuration for driving a foot support member included in the ankle exercise device. In the following description, “front”, “left”, “right”, and the like mean front, left, and right based on the user of the ankle exercise device 1.
　図１に示す足首運動装置１は、長時間にわたって同じ姿勢を取り続けること等により下肢に発生する血栓を予防するために、足首を運動させる装置である。足首運動装置１は、足先と踵を交互に上げる運動を使用者に行わせることにより、下肢の血液の流れを良くすることで、下肢に発生する血栓を予防することができる。また、この足首の運動によって、歩くのに欠かせない前脛骨筋、ヒラメ筋等の筋肉をトレーニングする効果を得ることができる。 The ankle exercise device 1 shown in FIG. 1 is a device for exercising the ankle in order to prevent blood clots generated in the lower limbs by keeping the same posture for a long time. The ankle exercise device 1 can prevent blood clots generated in the lower limbs by improving the blood flow in the lower limbs by causing the user to perform the exercise of alternately raising the toes and the heels. Moreover, the effect of training muscles such as the anterior tibial muscle and the soleus muscle, which are indispensable for walking, can be obtained by the exercise of the ankle.
　図１に示すように、足首運動装置１は、主として、中空箱状に形成されたケーシングとしてのベース部材２と、使用者の足を載せて支持する足支持部材３Ｌ，３Ｒと、ベース部材２内に収容され、足支持部材３Ｌ，３Ｒの姿勢を変更可能な姿勢変更機構１０と、を備える。 As shown in FIG. 1, the ankle exercise device 1 mainly includes a base member 2 as a casing formed in a hollow box shape, foot support members 3 </ b> L and 3 </ b> R for supporting a user's foot on the base member 2, and the base member 2. And a posture changing mechanism 10 that is housed inside and can change the posture of the foot support members 3L and 3R.
　本実施形態において、足支持部材３Ｌ，３Ｒ及び姿勢変更機構１０は、持ち運びが可能なベース部材２に対してコンパクトなレイアウトで設けられており、これにより、ポータブル型の足首運動装置１が実現されている。従って、使用者は、足首運動装置１を携帯して、長時間同じ姿勢を取ることが多い場所（例えば、乗物、自宅及び職場等）に容易に移動させ、床等の安定した場所に足首運動装置１を置いて使用することができる。 In the present embodiment, the foot support members 3L and 3R and the posture changing mechanism 10 are provided in a compact layout with respect to the portable base member 2, thereby realizing the portable ankle exercise device 1. ing. Therefore, the user carries the ankle exercise device 1 and easily moves it to a place (for example, a vehicle, a home, or a workplace) that often takes the same posture for a long time, and moves the ankle exercise to a stable place such as the floor. The device 1 can be placed and used.
　足支持部材３Ｌ，３Ｒは、使用者の足を載せるためのペダル状の部材であって、左右の対でベース部材２の上方に配置されている。 The foot support members 3L and 3R are pedal-like members on which the user's feet are placed, and are disposed above the base member 2 in pairs of left and right.
　図１に示すように、それぞれの足支持部材３Ｌ，３Ｒは前後方向に細長い板状に形成されており、何れも、その前後方向ほぼ中央部が、左右水平方向に配置された棒状の支持軸４により回転可能に支持されている。支持軸４の軸線（足支持部材３Ｌ，３Ｒの回転軸線）は、ベース部材２の上面よりも上方に位置している。これにより、左右の足支持部材３Ｌ，３Ｒは、側面視で支持軸４を支点としてシーソー状に回転し、その姿勢を前上がりと前下がりとの間で変化させることができので、使用者の足首を十分な角度で屈伸させることができる。 As shown in FIG. 1, each of the foot support members 3L, 3R is formed in a plate shape elongated in the front-rear direction, and both of them are rod-shaped support shafts whose substantially central part in the front-rear direction is disposed in the left-right horizontal direction. 4 is rotatably supported. The axis of the support shaft 4 (the rotation axis of the foot support members 3L and 3R) is located above the upper surface of the base member 2. As a result, the left and right foot support members 3L and 3R can rotate in a seesaw shape with the support shaft 4 as a fulcrum in a side view, and the posture thereof can be changed between front-up and front-down. The ankle can bend and stretch at a sufficient angle.
　ベース部材２内に収容される姿勢変更機構１０は、図１及び図２に示すように、電動モータ１１と、フライホイール１２と、駆動伝達機構１３と、第１クラッチ１４と、第２クラッチ１５と、ブレーキ１６と、を備えている。 As shown in FIGS. 1 and 2, the posture changing mechanism 10 housed in the base member 2 includes an electric motor 11, a flywheel 12, a drive transmission mechanism 13, a first clutch 14, and a second clutch 15. And a brake 16.
　電動モータ１１は、その出力軸３１の軸線を前後方向に水平に向けて配置されている。この電動モータ１１は、出力軸３１と軸線を一致させて回転可能に支持されたフライホイール１２を所定の方向に回転駆動することができる。 The electric motor 11 is arranged with its output shaft 31 oriented horizontally in the front-rear direction. The electric motor 11 can rotationally drive the flywheel 12 that is rotatably supported with the output shaft 31 and the axis aligned with each other in a predetermined direction.
　電動モータ１１の出力軸３１と、フライホイール１２と、の間には第１クラッチ１４が設けられている。この第１クラッチ１４はワンウェイクラッチとして構成されており、出力軸３１の回転をフライホイール１２に伝達する一方、フライホイール１２の回転を出力軸３１に伝達しないように構成されている。これにより、電動モータ１１によりフライホイール１２を駆動して十分な速度で回転させた状態で電動モータ１１を減速又は停止させたときに、フライホイール１２の回転に対して電動モータ１１が抵抗にならないようにすることができる。 A first clutch 14 is provided between the output shaft 31 of the electric motor 11 and the flywheel 12. The first clutch 14 is configured as a one-way clutch, and is configured to transmit the rotation of the output shaft 31 to the flywheel 12 while not transmitting the rotation of the flywheel 12 to the output shaft 31. Thus, when the electric motor 11 is decelerated or stopped while the flywheel 12 is driven by the electric motor 11 and rotated at a sufficient speed, the electric motor 11 does not become a resistance to the rotation of the flywheel 12. Can be.
　フライホイール１２は、回転することにより、足首運動装置１の各部（例えば、足支持部材３Ｌ，３Ｒ）を駆動するための運動エネルギーを蓄えることができる。また、フライホイール１２の慣性モーメントにより回転速度の変動を抑制することができるので、足支持部材３Ｌ，３Ｒを滑らかに動作させることができる。 The flywheel 12 can store kinetic energy for driving each part (for example, the foot support members 3L and 3R) of the ankle exercise device 1 by rotating. Moreover, since the fluctuation | variation of rotational speed can be suppressed with the moment of inertia of the flywheel 12, the foot support members 3L and 3R can be operated smoothly.
　駆動伝達機構１３は、主として、減速機２１と、クランクプレート（クランク部材）２２Ｌ，２２Ｒと、伝動リンク２３Ｌ，２３Ｒと、を備えている。 The drive transmission mechanism 13 mainly includes a speed reducer 21, crank plates (crank members) 22L and 22R, and transmission links 23L and 23R.
　減速機２１は、入力軸３４と、入力ベベルギア３５と、２つの出力ベベルギア３６Ｌ，３６Ｒと、２つの出力軸３７Ｌ，３７Ｒと、を備える。この減速機２１は、入力軸３４から入力した動力を減速しつつ左右に分配して、出力軸３７Ｌ，３７Ｒから出力することができる。 The reduction gear 21 includes an input shaft 34, an input bevel gear 35, two output bevel gears 36L and 36R, and two output shafts 37L and 37R. The speed reducer 21 can distribute the power input from the input shaft 34 to the left and right while decelerating and output the power from the output shafts 37L and 37R.
　入力ベベルギア３５は、フライホイール１２の軸線と一致するように回転可能に支持されており、この入力ベベルギア３５には、減速機２１の入力軸３４が固定されている。 The input bevel gear 35 is rotatably supported so as to coincide with the axis of the flywheel 12, and the input shaft 34 of the speed reducer 21 is fixed to the input bevel gear 35.
　この入力軸３４と、フライホイール１２との間には、第２クラッチ１５が設けられている。この第２クラッチ１５は例えば電磁クラッチとして構成されており、後述の制御部５から入力される電気信号に基づいて、フライホイール１２からの動力を駆動伝達機構１３の減速機２１に伝達する接続状態と、動力を伝達しない遮断状態と、を切り換えることができる。 A second clutch 15 is provided between the input shaft 34 and the flywheel 12. The second clutch 15 is configured as an electromagnetic clutch, for example, and is in a connected state in which power from the flywheel 12 is transmitted to the speed reducer 21 of the drive transmission mechanism 13 based on an electric signal input from the control unit 5 described later. And a cut-off state in which power is not transmitted.
　この第２クラッチ１５は、例えば、摩擦により動力を伝達する構成のものを用いることができる。この場合、クラッチ接続時のショックを和らげることができる。 The second clutch 15 may be configured to transmit power by friction, for example. In this case, the shock at the time of clutch connection can be eased.
　入力ベベルギア３５には、出力ベベルギア３６Ｌ，３６Ｒが同時に噛み合っている。２つの出力ベベルギア３６Ｌ，３６Ｒは、左右で向き合うように配置されており、何れも、入力ベベルギア３５と直交する水平な軸線まわりで回転可能に支持されている。 The output bevel gears 36L and 36R are meshed with the input bevel gear 35 at the same time. The two output bevel gears 36 </ b> L and 36 </ b> R are arranged to face each other on the left and right sides, and both are supported so as to be rotatable around a horizontal axis perpendicular to the input bevel gear 35.
　左側の出力ベベルギア３６Ｌには出力軸３７Ｌが固定され、右側の出力ベベルギア３６Ｒには出力軸３７Ｒが固定されている。左右の出力軸３７Ｌ，３７Ｒには、後述のクランクプレート２２Ｌ，２２Ｒがそれぞれ固定されている。 The output shaft 37L is fixed to the left output bevel gear 36L, and the output shaft 37R is fixed to the right output bevel gear 36R. Crank plates 22L and 22R, which will be described later, are fixed to the left and right output shafts 37L and 37R, respectively.
　この構成で、入力軸３４が駆動されると、入力ベベルギア３５に噛み合う２つの出力ベベルギア３６Ｌ，３６Ｒが、互いに等しい速度で逆向きに回転する。これにより、クランクプレート２２Ｌ，２２Ｒを、出力軸３７Ｌ，３７Ｒによって駆動することができる。 In this configuration, when the input shaft 34 is driven, the two output bevel gears 36L and 36R meshing with the input bevel gear 35 rotate in opposite directions at the same speed. Thus, the crank plates 22L and 22R can be driven by the output shafts 37L and 37R.
　ブレーキ１６は、例えば電磁ブレーキとして構成されており、ブレーキ軸４１を介してベベルギア４２と連結されている。このベベルギア４２は、減速機２１の出力ベベルギア３６Ｌ，３６Ｒに対して同時に噛み合っている。この構成で、図２に示す制御部５からの信号が入力されてブレーキ１６が動作すると、発生した制動力がブレーキ軸４１及びベベルギア４２を介して減速機２１に伝達され、回転が制動される。 The brake 16 is configured as an electromagnetic brake, for example, and is connected to the bevel gear 42 via the brake shaft 41. The bevel gear 42 meshes with the output bevel gears 36L and 36R of the speed reducer 21 at the same time. With this configuration, when the signal from the control unit 5 shown in FIG. 2 is input and the brake 16 operates, the generated braking force is transmitted to the speed reducer 21 via the brake shaft 41 and the bevel gear 42, and the rotation is braked. .
　上述したように、この減速機２１は、ベベルギア３５，３６Ｌ，３６Ｒを用いることで、フライホイール１２からの回転動力を９０°異なる向きで取り出して、クランクプレート２２Ｌ，２２Ｒに伝達するように構成されている。これにより、ベース部材２の内部の空間を有効に利用することができ、足首運動装置１を一層コンパクトにすることができる。 As described above, the speed reducer 21 uses the bevel gears 35, 36L, and 36R to extract the rotational power from the flywheel 12 in a direction different by 90 ° and transmit it to the crank plates 22L and 22R. ing. Thereby, the space inside the base member 2 can be used effectively, and the ankle exercise device 1 can be made more compact.
　また、ベベルギア３５，３６Ｌ，３６Ｒを用いることで、クランクプレート２２Ｌ，２２Ｒにおける互いに逆方向の回転を容易に実現できる。 Further, by using the bevel gears 35, 36L, 36R, the crank plates 22L, 22R can be easily rotated in opposite directions.
　左右のクランクプレート２２Ｌ，２２Ｒはそれぞれ円板状に構成されており、その外周縁の近傍の適宜の位置には、伝動リンク２３Ｌ，２３Ｒの端部が取り付けられている。伝動リンク２３Ｌ，２３Ｒは棒状に構成されており、その一端がクランクプレート２２Ｌ，２２Ｒに回転可能に連結され、他端が、足支持部材３Ｌ，３Ｒの前側下部に回転可能に連結されている。これにより、クランクプレート２２Ｌ，２２Ｒの回転を、足支持部材３Ｌ，３Ｒの所定角度範囲内での回転往復運動に変換することができる。 The left and right crank plates 22L and 22R are each formed in a disk shape, and the end portions of the transmission links 23L and 23R are attached to appropriate positions near the outer peripheral edge. The transmission links 23L and 23R are configured in a rod shape, one end of which is rotatably connected to the crank plates 22L and 22R, and the other end is rotatably connected to the front lower portions of the foot support members 3L and 3R. Thereby, rotation of the crank plates 22L and 22R can be converted into a reciprocating motion of the foot support members 3L and 3R within a predetermined angular range.
　以上の構成で、足首運動装置１に備えられる図示しない操作部を使用者が操作して運動開始が指示されると、電動モータ１１が駆動され、出力軸３１の回転動力が第１クラッチ１４を介してフライホイール１２に伝達されて、フライホイール１２が回転駆動される。そして、フライホイール１２の回転動力は、接続状態の第２クラッチ１５を介して、減速機２１の入力軸３４に伝達される。減速機２１は、入力軸３４の回転をベベルギア３５，３６Ｌ，３６Ｒにより減速して出力軸３７Ｌ，３７Ｒに伝達し、これによりクランクプレート２２Ｌ，２２Ｒが回転する。 With the above configuration, when the user operates an operation unit (not shown) provided in the ankle exercise device 1 to instruct the start of exercise, the electric motor 11 is driven, and the rotational power of the output shaft 31 causes the first clutch 14 to rotate. And the flywheel 12 is rotationally driven. Then, the rotational power of the flywheel 12 is transmitted to the input shaft 34 of the speed reducer 21 via the connected second clutch 15. The speed reducer 21 decelerates the rotation of the input shaft 34 by the bevel gears 35, 36L, and 36R and transmits it to the output shafts 37L and 37R, whereby the crank plates 22L and 22R rotate.
　次に、クランクプレート２２Ｌ，２２Ｒによる足支持部材３Ｌ，３Ｒの動作について、図３から図５までを参照して詳細に説明する。図３は、左右一側の足支持部材３Ｌが前上がり状態となり、他側の足支持部材３Ｒが前下がり状態となった様子を示す側面図である。図４は、左右の足支持部材３Ｌ，３Ｒがそれぞれ図３とは逆の姿勢となった様子を示す斜視図である。図５は、足首運動装置１を用いた足首の運動を説明する斜視図である。 Next, the operation of the foot support members 3L, 3R by the crank plates 22L, 22R will be described in detail with reference to FIGS. FIG. 3 is a side view showing a state in which the left and right foot support members 3L are in the forwardly raised state and the other foot support member 3R is in the forwardly lowered state. FIG. 4 is a perspective view showing the left and right foot support members 3L and 3R in a posture opposite to that in FIG. FIG. 5 is a perspective view for explaining the movement of the ankle using the ankle exercise device 1.
　伝動リンク２３Ｌ，２３Ｒはクランクプレート２２Ｌ，２２Ｒに連結されているので、クランクプレート２２Ｌ，２２Ｒの回転に従って、伝動リンク２３Ｌ，２３Ｒが押し上げられたり引き下げられたりする。この結果、足支持部材３Ｌ，３Ｒは、図３及び図４に示すように、前部が伝動リンク２３Ｌ，２３Ｒにより上側に押されることで前上がり姿勢となり、前部が伝動リンク２３Ｌ，２３Ｒにより下に引っ張られることで前下がり姿勢となる。このように、足支持部材３Ｌ，３Ｒは、支持軸４を支点として所定角度範囲内で回転する。 Since the transmission links 23L and 23R are connected to the crank plates 22L and 22R, the transmission links 23L and 23R are pushed up and down as the crank plates 22L and 22R rotate. As a result, as shown in FIG. 3 and FIG. 4, the foot support members 3L and 3R are in a front-up posture when the front part is pushed upward by the transmission links 23L and 23R, and the front part is transmitted by the transmission links 23L and 23R. Pulled down to be in a forward-down position. Thus, the foot support members 3L and 3R rotate within a predetermined angle range with the support shaft 4 as a fulcrum.
　左右の伝動リンク２３Ｌ，２３Ｒがクランクプレート２２Ｌ，２２Ｒに取り付けられる位置（位相）は、一方が上端であるとき、他方が下端となるように定められている。左右のクランクプレート２２Ｌ，２２Ｒは互いに等しい速度で逆向きに回転するので、左右の伝動リンク２３Ｌ，２３Ｒは、一方が押し上げられるときに、他方が引き下げられることになる。 The positions (phases) at which the left and right transmission links 23L and 23R are attached to the crank plates 22L and 22R are determined such that when one is the upper end, the other is the lower end. Since the left and right crank plates 22L and 22R rotate in opposite directions at the same speed, the left and right transmission links 23L and 23R are pulled down when one is pushed up.
　これにより、図３に示すように、左側の足支持部材３Ｌが前上がり状態となるときは、右側の足支持部材３Ｒが前下がり状態となる。また、図４に示すように、左側の足支持部材３Ｌが前下がり状態となるときは、右側の足支持部材３Ｒが前上がり状態となる。更に、左右の足支持部材３Ｌ，３Ｒは、一方が前部を上昇させるように傾くのと同時に、他方が前部を下降させるように傾く。 Thus, as shown in FIG. 3, when the left foot support member 3L is in the forwardly raised state, the right foot support member 3R is in the forwardly lowered state. Further, as shown in FIG. 4, when the left foot support member 3L is in the forwardly lowered state, the right foot support member 3R is in the forwardly raised state. Furthermore, one of the left and right foot support members 3L and 3R is tilted so as to raise the front part, and the other is tilted so as to lower the front part.
　これにより、図３と図４の状態が交互に繰り返し実現され、図５に示すように、使用者の足首を、あたかも歩行しているかのように左右交互に運動させることができる。 3 and 4 are alternately and repeatedly realized, and the user's ankle can be moved alternately left and right as if walking, as shown in FIG.
　次に、足首運動装置１における制御について説明する。 Next, control in the ankle exercise device 1 will be described.
　足首運動装置１は、図２に示すように制御部５を備えている。この制御部５は公知のコンピュータとして構成され、ベース部材２の内部に収容されている。 The ankle exercise device 1 includes a control unit 5 as shown in FIG. The control unit 5 is configured as a known computer and is accommodated in the base member 2.
　制御部５は、フライホイール１２の回転速度に応じて、電動モータ１１の駆動及び停止を制御する。具体的には、制御部５はフライホイール１２の回転速度を回転センサ４５により検出し、当該回転速度が予め設定された所定速度を上回ると、電動モータ１１を停止させるように構成されている。 The control unit 5 controls the driving and stopping of the electric motor 11 according to the rotational speed of the flywheel 12. Specifically, the control unit 5 is configured to detect the rotational speed of the flywheel 12 with the rotation sensor 45 and stop the electric motor 11 when the rotational speed exceeds a preset predetermined speed.
　この構成で、フライホイール１２の回転が停止した状態で使用者により運動開始が指示されると、制御部５は、電動モータ１１がフライホイール１２の回転駆動を開始するように制御する。制御部５はフライホイール１２の回転速度を回転センサ４５により監視し、この回転速度が所定値を上回ったことが検知されると、電動モータ１１の駆動を停止させる。なお、電動モータ１１の停止後も、フライホイール１２で蓄積したエネルギーにより、足支持部材３Ｌ，３Ｒの動作を継続することができる。 In this configuration, when the user gives an instruction to start exercise while the rotation of the flywheel 12 is stopped, the control unit 5 controls the electric motor 11 to start the rotational drive of the flywheel 12. The control unit 5 monitors the rotational speed of the flywheel 12 with the rotation sensor 45 and stops driving the electric motor 11 when it is detected that the rotational speed exceeds a predetermined value. Even after the electric motor 11 is stopped, the operation of the foot support members 3L and 3R can be continued by the energy accumulated in the flywheel 12.
　そして、制御部５は、フライホイール１２の回転が減衰して上記の所定値よりも一定程度遅くなったことが回転センサ４５により検知されると、再び電動モータ１１を駆動させ、フライホイール１２を所定速度まで加速させる。即ち、足支持部材３Ｌ，３Ｒの動力源であるフライホイール１２は、電動モータ１１により間欠的に回転駆動される。 Then, when the rotation sensor 45 detects that the rotation of the flywheel 12 is attenuated and is slower than the predetermined value by the rotation sensor 45, the control unit 5 drives the electric motor 11 again, Accelerate to a predetermined speed. That is, the flywheel 12 that is the power source of the foot support members 3L and 3R is intermittently driven to rotate by the electric motor 11.
　これにより、フライホイール１２の回転速度が十分でない場合（運動開始の初期等）にのみ、電動モータ１１を用いて装置を駆動するため、少ない電力で利用でき、装置の省エネルギー性を高めることができる。また、使用者は、足支持部材３Ｌ，３Ｒを足で力強く踏んで、足支持部材３Ｌ，３Ｒに交互動作を通常より高速で行わせたり、足支持部材３Ｌ，３Ｒの姿勢変化を妨げるように足に力を入れて動作速度が減衰する感覚を得たりする等、慣性による動きの変化を楽しみながら運動を行うことができる。 Thereby, since the apparatus is driven by using the electric motor 11 only when the rotational speed of the flywheel 12 is not sufficient (eg, at the beginning of exercise), the apparatus can be used with a small amount of power, and the energy saving performance of the apparatus can be improved. . In addition, the user steps on the foot support members 3L and 3R with his / her foot to cause the foot support members 3L and 3R to perform an alternate operation at a higher speed than usual or to prevent the posture change of the foot support members 3L and 3R. It is possible to exercise while enjoying the change of movement due to inertia, such as obtaining a sense that the motion speed is attenuated by applying force to the foot.
　以上に説明したように、本実施形態の足首運動装置１は、ベース部材２と、左右の対でベース部材２に配置される足支持部材３Ｌ，３Ｒと、足支持部材３Ｌ，３Ｒの姿勢を前上がりと前下がりとの間で変更可能な姿勢変更機構１０と、を備える。姿勢変更機構１０は、電動モータ１１と、当該電動モータ１１によって駆動されるフライホイール１２と、フライホイール１２の回転を足支持部材３Ｌ，３Ｒに伝達する駆動伝達機構１３と、を備える。 As described above, the ankle exercise device 1 of the present embodiment has the base member 2, the foot support members 3L and 3R disposed on the base member 2 in a pair of left and right, and the postures of the foot support members 3L and 3R. And a posture changing mechanism 10 that can be changed between front-up and front-down. The posture changing mechanism 10 includes an electric motor 11, a flywheel 12 driven by the electric motor 11, and a drive transmission mechanism 13 that transmits the rotation of the flywheel 12 to the foot support members 3L and 3R.
　これにより、容易に持ち運ぶことが可能なシンプルな構成を実現できるとともに、使用者の足先及び踵を上下に動かすことにより足首の十分な屈伸を行わせることができる。また、フライホイール１２を用いて足支持部材３Ｌ，３Ｒの姿勢を変更することで、足支持部材３Ｌ，３Ｒの姿勢変更動作を滑らかに行うことができる。更に、フライホイール１２の回転により蓄積したエネルギーを利用可能になるので、装置の省電力性を向上させることができる。 This makes it possible to realize a simple configuration that can be easily carried and to allow the ankle to bend and stretch sufficiently by moving the user's toes and heels up and down. Further, by changing the postures of the foot support members 3L and 3R using the flywheel 12, the posture changing operation of the foot support members 3L and 3R can be performed smoothly. Furthermore, since the energy accumulated by the rotation of the flywheel 12 can be used, the power saving performance of the apparatus can be improved.
　また、本実施形態の足首運動装置１において、姿勢変更機構１０は、左右の足支持部材３Ｌ，３Ｒのうち一方の姿勢を前上がり方向に変化させると同時に、他方の姿勢を前下がり方向に変化させる。 Further, in the ankle exercise device 1 of the present embodiment, the posture changing mechanism 10 changes one posture of the left and right foot support members 3L, 3R in the forward upward direction and simultaneously changes the other posture in the forward downward direction. Let
　これにより、使用者の足首を左右交互に動かし、歩行時のような運動を行うことができる。 This allows the user's ankles to move alternately left and right to perform movements as if walking.
　また、本実施形態の足首運動装置１は、電動モータ１１とフライホイール１２との間に第１クラッチ１４が配置され、フライホイール１２と駆動伝達機構１３の減速機２１との間に第２クラッチ１５が配置される。 In the ankle exercise device 1 of the present embodiment, the first clutch 14 is disposed between the electric motor 11 and the flywheel 12, and the second clutch is disposed between the flywheel 12 and the speed reducer 21 of the drive transmission mechanism 13. 15 is arranged.
　これにより、電動モータ１１とフライホイール１２との間、及び、フライホイール１２と駆動伝達機構１３との間において、動力の伝達及び遮断を切り替えることができる。従って、例えば、足支持部材３Ｌ，３Ｒの動作を必要に応じて素早く止めることができる。 Thereby, transmission and interruption of power can be switched between the electric motor 11 and the flywheel 12 and between the flywheel 12 and the drive transmission mechanism 13. Therefore, for example, the operation of the foot support members 3L and 3R can be quickly stopped as necessary.
　また、本実施形態の足首運動装置１は、電動モータ１１の駆動及び停止を制御する制御部５を備える。制御部５は、足支持部材３Ｌ，３Ｒの姿勢変更動作中に電動モータ１１を停止することが可能である。 Further, the ankle exercise device 1 of the present embodiment includes a control unit 5 that controls driving and stopping of the electric motor 11. The control unit 5 can stop the electric motor 11 during the posture changing operation of the foot support members 3L and 3R.
　これにより、フライホイール１２の慣性回転により足支持部材３Ｌ，３Ｒの駆動を行うことができるので、足首運動装置１の省電力性を確実に高めることができる。 Thereby, since the foot support members 3L and 3R can be driven by the inertial rotation of the flywheel 12, the power saving performance of the ankle exercise device 1 can be reliably improved.
　次に、第２実施形態を説明する。図６は、第２実施形態の足首運動装置１ｘにおいて、左足支持部材３Ｌだけが動いている様子を示す斜視図である。図７は、第２実施形態の足首運動装置１ｘの構成の概略を示す平面図である。なお、本実施形態の説明においては、前述の実施形態と同一又は類似の部材には図面に同一の符号を付し、説明を省略する場合がある。 Next, a second embodiment will be described. FIG. 6 is a perspective view showing a state where only the left foot support member 3L is moving in the ankle exercise device 1x of the second embodiment. FIG. 7 is a plan view schematically illustrating the configuration of the ankle exercise device 1x according to the second embodiment. In the description of the present embodiment, the same or similar members as those of the above-described embodiment may be denoted by the same reference numerals in the drawings, and description thereof may be omitted.
　本実施形態の足首運動装置１ｘにおいて、図６に示すように、姿勢変更機構１０ｘの駆動伝達機構１３ｘは、第３クラッチ３８Ｌ及び第４クラッチ３８Ｒを更に備える。図７に示すように、当該第３クラッチ３８Ｌ及び第４クラッチ３８Ｒの作動は、制御部５により制御される。 In the ankle exercise device 1x of this embodiment, as shown in FIG. 6, the drive transmission mechanism 13x of the posture changing mechanism 10x further includes a third clutch 38L and a fourth clutch 38R. As shown in FIG. 7, the operations of the third clutch 38L and the fourth clutch 38R are controlled by the control unit 5.
　第３クラッチ３８Ｌは、減速機２１の出力軸３７Ｌと、クランクプレート２２Ｌと、の間に設置され、例えば電磁クラッチとして構成される。第３クラッチ３８Ｌは、制御部５から入力される電気信号に基づいて、減速機２１からの動力をクランクプレート２２Ｌに伝達する接続状態と、動力を伝達しない遮断状態と、を切り換えることができる。 The third clutch 38L is installed between the output shaft 37L of the speed reducer 21 and the crank plate 22L, and is configured as an electromagnetic clutch, for example. Based on the electrical signal input from the control unit 5, the third clutch 38L can switch between a connected state in which the power from the reduction gear 21 is transmitted to the crank plate 22L and a disconnected state in which the power is not transmitted.
　第４クラッチ３８Ｒは、減速機２１の出力軸３７Ｒと、クランクプレート２２Ｒと、の間に設置され、例えば電磁クラッチとして構成される。第４クラッチ３８Ｒは、制御部５から入力される電気信号に基づいて、減速機２１からの動力をクランクプレート２２Ｒに伝達する接続状態と、動力を伝達しない遮断状態と、を切り換えることができる。 The fourth clutch 38R is installed between the output shaft 37R of the speed reducer 21 and the crank plate 22R, and is configured as an electromagnetic clutch, for example. Based on the electrical signal input from the control unit 5, the fourth clutch 38R can switch between a connected state in which power from the reduction gear 21 is transmitted to the crank plate 22R and a disconnected state in which power is not transmitted.
　制御部５は、第３クラッチ３８Ｌ及び第４クラッチ３８Ｒの作動を制御することで、減速機２１からの動力を連続的又は間欠的にクランクプレート２２Ｌ，２２Ｒへ伝達することができる。 The control unit 5 can transmit the power from the speed reducer 21 to the crank plates 22L and 22R continuously or intermittently by controlling the operation of the third clutch 38L and the fourth clutch 38R.
　制御部５は、第３クラッチ３８Ｌ及び第４クラッチ３８Ｒをそれぞれ独立して制御することができる。従って、左右の足支持部材３Ｌ，３Ｒのうち何れかを単独で動かすように、第３クラッチ３８Ｌ及び第４クラッチ３８Ｒの作動を制御し、減速機２１からの動力を片側のクランクプレート（２２Ｌ又は２２Ｒ）にのみ伝達させることもできる。 The control unit 5 can control the third clutch 38L and the fourth clutch 38R independently of each other. Therefore, the operation of the third clutch 38L and the fourth clutch 38R is controlled so that one of the left and right foot support members 3L, 3R is moved independently, and the power from the speed reducer 21 is supplied to one crank plate (22L or 22R) can also be transmitted.
　また、制御部５は、左右の足支持部材３Ｌ，３Ｒについて、左右で異なるタイミングで姿勢変更動作の開始／停止が行われるように、第３クラッチ３８Ｌ及び第４クラッチ３８Ｒの作動を制御することができる。これにより、足支持部材３Ｌ，３Ｒにおけるバリエーション豊かな動きを実現することができるので、運動の単調さを回避でき、運動の継続を促すことができる。 In addition, the control unit 5 controls the operation of the third clutch 38L and the fourth clutch 38R so that the posture changing operation is started / stopped at different timings for the left and right foot support members 3L and 3R. Can do. Thereby, since the variation-rich movement in the foot support members 3L and 3R can be realized, the monotonousness of the movement can be avoided and the continuation of the movement can be promoted.
　具体的には、下記の例のように、左右の足支持部材３Ｌ，３Ｒにおける多彩な動きを実現することができる。 Specifically, as shown in the following example, various movements in the left and right foot support members 3L and 3R can be realized.
　本実施形態の足首運動装置１ｘは、複数の動作モードを有している。使用者は、足首運動装置１ｘが備える操作部を介して、複数の動作モードから１の動作モードを選択する。この操作部は、例えば、リモートコントローラや、ベース部材２に設けられたスイッチ及び表示部や、ベース部材２に設けられたタッチパネル等から構成することができる。 The ankle exercise device 1x of the present embodiment has a plurality of operation modes. The user selects one operation mode from a plurality of operation modes via the operation unit included in the ankle exercise device 1x. This operation part can be comprised from the remote controller, the switch and display part provided in the base member 2, the touch panel provided in the base member 2, etc., for example.
　上記動作モードは、例えば、通常モード、単独運動モード、眠気防止モード、リズム体操モード、音楽体験モード等を含むことができる。 The above operation modes can include, for example, a normal mode, a single exercise mode, a drowsiness prevention mode, a rhythmic exercise mode, a music experience mode, and the like.
　足首運動装置１ｘは図略の記憶部を備えており、この記憶部は、第３クラッチ３８Ｌ及び第４クラッチ３８Ｒを制御するために予め設定された複数の制御データを記憶している。制御部５は、使用者が操作部を介して選択された動作モードに対応する制御データを記憶部から取得し、取得した制御データに基づいて第３クラッチ３８Ｌ及び第４クラッチ３８Ｒの作動を制御する。 The ankle exercise device 1x includes a storage unit (not shown), and the storage unit stores a plurality of control data set in advance for controlling the third clutch 38L and the fourth clutch 38R. The control unit 5 acquires control data corresponding to the operation mode selected by the user via the operation unit from the storage unit, and controls the operation of the third clutch 38L and the fourth clutch 38R based on the acquired control data. To do.
　通常モードが選択された場合、制御部５は、減速機２１からの動力をクランクプレート２２Ｌ，２２Ｒへ伝達するように、第３クラッチ３８Ｌ及び第４クラッチ３８Ｒの作動を制御し、減速機２１からの動力を左右の足支持部材３Ｌ，３Ｒに伝達させる。これにより、第１実施形態で説明したように、使用者の足首を左右交互に動かし、歩行時のような運動を行うことができる。 When the normal mode is selected, the control unit 5 controls the operation of the third clutch 38L and the fourth clutch 38R so as to transmit the power from the speed reducer 21 to the crank plates 22L and 22R. Is transmitted to the left and right foot support members 3L, 3R. Thereby, as demonstrated in 1st Embodiment, a user's ankle can be moved alternately right and left, and exercise | movement like the time of a walk can be performed.
　単独運動モード（例えば、左足首運動）が選択された場合、制御部５は、減速機２１からの動力を左足支持部材３Ｌにのみ伝達するように、第３クラッチ３８Ｌ及び第４クラッチ３８Ｒの作動を制御する。これにより、使用者は、左右片側だけの足首を動かすことができる。 When the single motion mode (for example, left ankle motion) is selected, the control unit 5 operates the third clutch 38L and the fourth clutch 38R so as to transmit the power from the speed reducer 21 only to the left foot support member 3L. To control. Thereby, the user can move the ankle only on the left and right sides.
　眠気防止モードが選択された場合、第３クラッチ３８Ｌ及び第４クラッチ３８Ｒの作動を制御するために制御部５が選択する制御データは、左右の足支持部材３Ｌ，３Ｒが不規則的なタイミングで運動の開始／停止を行うように定められている。なお、制御データによらず、例えば、乱数によって第３クラッチ３８Ｌ及び第４クラッチ３８Ｒの接続／遮断タイミングを決定しても良い。このように、使用者の左右足首に規律がない動きをさせることで、使用者の眠気を覚ますことができるとともに、普段しない動きにより、脳を鍛える効果も期待することができる。 When the drowsiness prevention mode is selected, the control data selected by the control unit 5 for controlling the operation of the third clutch 38L and the fourth clutch 38R is that the left and right foot support members 3L, 3R are at irregular timings. It is defined to start / stop exercise. For example, the connection / disconnection timing of the third clutch 38L and the fourth clutch 38R may be determined by a random number regardless of the control data. In this way, by making the user's left and right ankles move without discipline, the user's sleepiness can be awakened, and the effect of training the brain can be expected due to unusual movement.
　この眠気防止モードにおいては、運動の開始／停止が切り換わる平均的な頻度を、使用者の操作によって変化させることが可能に構成することもできる。なお、この頻度の切換に連動して、電動モータ１１の回転速度を変更制御することが可能に構成しても良い。これにより、使用者が望む動きのペースに応じて足支持部材３Ｌ，３Ｒを動かすことができる。 In this sleepiness prevention mode, the average frequency at which the start / stop of the exercise is switched can be changed by the operation of the user. In addition, you may comprise so that change control of the rotational speed of the electric motor 11 may be interlocked with the switching of this frequency. Thereby, the foot support members 3L and 3R can be moved in accordance with the pace of movement desired by the user.
　また、制御部５は、他の動作モードにおいて使用者の眠気を検知した場合、自動的に眠気防止モードに切り替えることもできる。具体的には、例えば、制御部５は、リモートコントローラ、足支持部材３Ｌ，３Ｒの何れ又は両方、ベース部材２等に設けられた図略の人体センサからの検出値に基づいて使用者が眠くなっているか否かを判定し、眠くなっていると判定した場合、自動的に眠気防止モードに切り替える。人体センサとしては、例えば、心拍、呼吸数、血圧、筋肉の弛緩等を検出するセンサが考えられるが、これに限定されない。 Also, the control unit 5 can automatically switch to the sleepiness prevention mode when the user's sleepiness is detected in another operation mode. Specifically, for example, the control unit 5 makes the user sleep based on a detection value from a human body sensor (not shown) provided on the remote controller, the foot support members 3L and 3R, the base member 2 or the like. If it is determined whether or not it is sleepy, it automatically switches to the sleepiness prevention mode. Examples of the human body sensor include, but are not limited to, sensors that detect heartbeat, respiratory rate, blood pressure, muscle relaxation, and the like.
　リズム体操モードが選択された場合、制御部５は、左右の足支持部材３Ｌ，３Ｒに対する、体操に適した所定のリズムに合わせた動きを実現する制御データに基づいて、左右の足支持部材３Ｌ，３Ｒが運動の開始／停止を行うように制御する。これにより、足首運動の楽しさを一層向上させることができる。そして、そのリズムに合わせて上半身も動くことで、座ったままでも、楽しくリズム体操をすることができる。更に、使用者の足首を一定のリズムで動かすことによって、使用者の下肢に物理的な刺激を与え、大脳の前頭葉の機能を改善し、認知症改善の効果も図ることができる。なお、開始／停止のリズムに合わせたテンポで、図略のスピーカーからブザー音を鳴らしたり、ランプを光らせたりしても良い。 When the rhythm exercise mode is selected, the control unit 5 controls the left and right foot support members 3L based on the control data for realizing the movement in accordance with a predetermined rhythm suitable for the exercise with respect to the left and right foot support members 3L and 3R. , 3R is controlled to start / stop motion. Thereby, the pleasure of ankle exercise can be further improved. And by moving the upper body according to the rhythm, you can enjoy rhythmic exercises while sitting. Furthermore, by moving the user's ankle at a constant rhythm, physical stimulation is given to the user's lower limbs, the function of the frontal lobe of the cerebrum is improved, and the effect of improving dementia can be achieved. A buzzer sound or a lamp may be emitted from a speaker (not shown) at a tempo that matches the start / stop rhythm.
　音楽体験モードが選択された場合、制御部５は、前記記憶部に記憶した音声データをスピーカーから流すように制御するとともに、当該音声データの音楽に同期した動きを出す制御データに基づいて、左右の足支持部材３Ｌ，３Ｒが運動の開始／停止を行うように制御する。これにより、使用者の足首を律動的に動かすことができるので、単調な足首運動に面白みを与えることができるとともに、律動運動による血流の改善等の効果も図ることができる。 When the music experience mode is selected, the control unit 5 controls the audio data stored in the storage unit to flow from the speaker, and based on the control data that moves in synchronization with the music of the audio data, The foot support members 3L and 3R are controlled to start / stop movement. Thereby, since a user's ankle can be moved rhythmically, while being able to give interest to a monotonous ankle exercise | movement, effects, such as improvement of the blood flow by rhythm exercise | movement, can also be aimed at.
　また、この音楽体験モードは、足首運動装置１に予め設定された所定の音楽に連動して運動の開始／停止を行うことに限定されない。例えば、ベース部材２又は上記リモートコントローラ等に設けられた図略のマイクを介して周囲の音を取り込み、制御部５がその音声レベル等を解析することで制御データをリアルタイムで生成し、当該制御データに基づいて左右の足支持部材３Ｌ，３Ｒの動きを制御することが考えられる。これにより、使用者の好みの音楽に合わせて足首を動かすことができるので、使用者の心が落ち着き易い状態で足首を運動することができ、適度の運動と呼吸改善により、脳内のセロトニン神経が強化され、うつ病の改善等の効果も期待できる。 Further, the music experience mode is not limited to starting / stopping exercise in conjunction with predetermined music preset in the ankle exercise device 1. For example, the surrounding sound is captured via a microphone (not shown) provided in the base member 2 or the remote controller, and the control unit 5 generates control data in real time by analyzing the sound level and the like. It is conceivable to control the movement of the left and right foot support members 3L, 3R based on the data. As a result, the ankle can be moved according to the user's favorite music, so the ankle can be exercised in a state where the user's mind is easy to calm down. Can be strengthened and can be expected to improve depression.
　以上に説明したように、本実施形態の足首運動装置１ｘにおいて、姿勢変更機構１０ｘは、出力軸３７Ｌ，３７Ｒと、第３クラッチ３８Ｌ及び第４クラッチ３８Ｒと、を備える。出力軸３７Ｌ，３７Ｒは、足支持部材３Ｌ，３Ｒに動力を伝達する。第３クラッチ３８Ｌ及び第４クラッチ３８Ｒは、出力軸３７Ｌ，３７Ｒと左右の足支持部材３Ｌ，３Ｒのそれぞれとの間に設置される。 As described above, in the ankle exercise device 1x of the present embodiment, the posture changing mechanism 10x includes the output shafts 37L and 37R, the third clutch 38L, and the fourth clutch 38R. The output shafts 37L and 37R transmit power to the foot support members 3L and 3R. The third clutch 38L and the fourth clutch 38R are installed between the output shafts 37L, 37R and the left and right foot support members 3L, 3R, respectively.
　これにより、電動モータ１１を共通としつつ、左右の足支持部材３Ｌ，３Ｒのそれぞれに対して動力の伝達／遮断を独立で切り換えることが可能になり、バリエーション豊かな動きを実現することができる。 This makes it possible to independently switch the transmission / cutoff of power to each of the left and right foot support members 3L and 3R while using the electric motor 11 in common, and realize a variety of movements.
　また、本実施形態の足首運動装置１ｘは、制御部５を備える。制御部５は、足支持部材３Ｌ，３Ｒへの動力の伝達／遮断を切り換えるように、第３クラッチ３８Ｌ及び第４クラッチ３８Ｒを制御する。制御部５は、連続的又は間欠的に動力を足支持部材３Ｌ，３Ｒへ伝達するように第３クラッチ３８Ｌ及び第４クラッチ３８Ｒの作動を制御可能である。制御部５は、左右の前記足支持部材３Ｌ，３Ｒに対して、動力の伝達及び遮断の少なくとも何れかを左右で異なるタイミングで行うように第３クラッチ３８Ｌ及び第４クラッチ３８Ｒを制御可能である。 Further, the ankle exercise device 1x of the present embodiment includes a control unit 5. The control unit 5 controls the third clutch 38L and the fourth clutch 38R so as to switch transmission / cutoff of power to the foot support members 3L, 3R. The controller 5 can control the operation of the third clutch 38L and the fourth clutch 38R so as to transmit power to the foot support members 3L, 3R continuously or intermittently. The control unit 5 can control the third clutch 38L and the fourth clutch 38R so as to perform at least one of transmission and interruption of power to the left and right foot support members 3L and 3R at different timings on the left and right. .
　これにより、例えば、左右の足支持部材３Ｌ，３Ｒをそれぞれランダムに動かすことで眠気を解消することができる。また、例えば、体操リズム、音楽のテンポ等に合わせて左右の足支持部材３Ｌ，３Ｒを動かすことで、単調な足首運動に面白みを与えることができる。 Thereby, for example, drowsiness can be eliminated by randomly moving the left and right foot support members 3L and 3R. Further, for example, by moving the left and right foot support members 3L and 3R according to the gymnastic rhythm, music tempo, etc., it is possible to add interest to monotonous ankle movement.
　以上に本発明の好適な実施の形態を説明したが、上記の構成は例えば以下のように変更することができる。 Although a preferred embodiment of the present invention has been described above, the above configuration can be modified as follows, for example.
　伝動リンク２３Ｌ，２３Ｒの押上げ及び引下げは、クランクプレート２２Ｌ，２２Ｒに代えて、他の構成のクランク部材、例えば、クランクアーム、クランクシャフト等によって実現することもできる。また、クランク機構ではなく、例えば溝カム等のカム機構を用いて足支持部材３Ｌ，３Ｒの動作を実現することもできる。 The push-up and pull-down of the transmission links 23L and 23R can be realized by a crank member having another configuration, for example, a crank arm, a crankshaft or the like, instead of the crank plates 22L and 22R. Further, the operation of the foot support members 3L and 3R can be realized by using a cam mechanism such as a groove cam instead of the crank mechanism.
　電動モータ１１等の動力源として、ベース部材２の内部又は外部に充電式のバッテリーが備えられても良い。あるいは、例えば家庭用電源等の外部の電力源から電源ケーブルを介して電力を供給するように構成しても良い。 As a power source for the electric motor 11 or the like, a rechargeable battery may be provided inside or outside the base member 2. Alternatively, for example, power may be supplied from an external power source such as a household power source via a power cable.
　第１クラッチ１４、第２クラッチ１５は、上記種類のクラッチに限定せず、例えば、粘性や電磁力を用いる方式のクラッチを使用することもできる。 The first clutch 14 and the second clutch 15 are not limited to the above-mentioned type of clutch, and for example, a clutch using a viscosity or electromagnetic force may be used.
　運動を止める時に、フライホイール１２の回転エネルギーを電気エネルギーに変換して、足首運動装置１に設けられたバッテリーに回収することもできる。こうして得られた回生電力は、再び電動モータ１１でフライホイール１２を回転駆動するときに使用される。この構成では、省電力性を一層高めることができる。 When the movement is stopped, the rotational energy of the flywheel 12 can be converted into electric energy and collected in a battery provided in the ankle exercise device 1. The regenerative electric power obtained in this way is used when the flywheel 12 is rotationally driven by the electric motor 11 again. With this configuration, power saving can be further enhanced.
　左右の足支持部材３Ｌ，３Ｒを、交互にではなく、その傾斜姿勢が左右で常に一致するように動作させても良い。例えば、左右の伝動リンク２３Ｌ，２３Ｒを、クランクプレート２２Ｌ，２２Ｒに対して、一方が上端であるとき他方も上端となるように、かつ、一方が下端であるとき他方も下端となるように取り付ければ良い。 The left and right foot support members 3L and 3R may be operated so that their inclined postures always coincide with each other, not alternately. For example, the left and right transmission links 23L, 23R are attached to the crank plates 22L, 22R so that when one is the upper end, the other is also the upper end, and when one is the lower end, the other is the lower end. It ’s fine.
　減速機２１において左右の出力ベベルギア３６Ｌ，３６Ｒのうち一方を省略して、他方の出力ベベルギアに左右両方のクランクプレート２２Ｌ，２２Ｒを連結して、その回転方向を一致させても良い。この場合、左右の伝動リンク２３Ｌ，２３Ｒのクランクプレート２２Ｌ，２２Ｒに対する取付位相を互いに１８０°異ならせることで、左右の足支持部材３Ｌ，３Ｒを互い違いに動作させることができる。また、上記の取付位相を互いに一致させると、左右の足支持部材３Ｌ，３Ｒの姿勢を一致させることができる。 In the speed reducer 21, one of the left and right output bevel gears 36L and 36R may be omitted, and both the left and right crank plates 22L and 22R may be connected to the other output bevel gear so that the rotation directions thereof coincide. In this case, the left and right foot support members 3L and 3R can be operated alternately by making the mounting phases of the left and right transmission links 23L and 23R different from each other by 180 °. Further, when the above attachment phases are matched with each other, the postures of the left and right foot support members 3L and 3R can be matched.
　ブレーキ１６は、例えば減速機２１の入力軸３４に配置されても良い。この場合、ベベルギア４２及びブレーキ軸４１を省略することができる。 The brake 16 may be disposed on the input shaft 34 of the speed reducer 21, for example. In this case, the bevel gear 42 and the brake shaft 41 can be omitted.
　単独運動モードは、リズム体操モード又は音楽体験モードと同時に実行することも可能である。この場合、片足だけのリズム体操モード等が実現される。 The single exercise mode can be executed simultaneously with the rhythm exercise mode or the music experience mode. In this case, a rhythmic exercise mode or the like of only one foot is realized.
　左右の足支持部材３Ｌ，３Ｒを、左右個別に設けられた電動機により駆動する構成も可能である。 A configuration in which the left and right foot support members 3L and 3R are driven by electric motors separately provided on the left and right sides is also possible.
　リモコン等に動き検出センサを設置し、当該センサからの検出データに基づいて、足支持部材３Ｌ，３Ｒを動かすこともできる。これにより、使用者の上半身の動きに合わせて、足支持部材３Ｌ，３Ｒを動かすことができるので、使用者が足首運動の楽しさを味わうことができる。 It is also possible to install a motion detection sensor on the remote controller or the like and move the foot support members 3L and 3R based on detection data from the sensor. Thereby, since the foot support members 3L and 3R can be moved in accordance with the movement of the upper body of the user, the user can enjoy the fun of ankle movement.
