JP 2010-207570 A

上記特許文献1の揺動運動器具は、乗載部を上下方向と左右方向の2方向に揺動させるため、乗載部を1方向に揺動させる場合に比べて、筋肉をムラなく振動させることが可能であるが、クランク機構を用いて乗載部を揺動させる方向を、2方向、3方向…と増やすほど、複雑なクランク機構が必要となってコスト高となる。   Since the swing exercise device of Patent Document 1 swings the mounting portion in two directions, the vertical direction and the left-right direction, the muscles vibrate more evenly than when the mounting portion swings in one direction. However, as the direction in which the mounting portion is swung using the crank mechanism is increased to two directions, three directions, etc., a complicated crank mechanism is required and the cost increases.

本発明はかかる現状に鑑みてなされたものであり、乗載部の揺動方向を比較的低廉に増やすことが可能な揺動運動器具の提供を目的とする。   The present invention has been made in view of the present situation, and an object thereof is to provide a swing exerciser capable of increasing the swing direction of the mounting portion relatively inexpensively.

本発明は、床に載置されるベースと、該ベースに上下方向、及び/又は左右方向に揺動可能に保持される中間フレームと、該中間フレームをベースに対して上下方向、及び/又は左右方向に揺動させる揺動機構と、体の一部又は全部を載置する乗載面が上面に形成された乗載部と、中間フレームと乗載部の間に介装されて、乗載部を、中間フレームの上の所定の原点位置に保持し、乗載部に対して乗載面に沿った方向に外力が加わると、中間フレームに対して乗載部を該外力の方向に変位させるとともに、乗載部を原点位置に付勢する付勢力を発生させる保持手段と、乗載部の底部に固定されて、回転軸を乗載面と略垂直に下方突出させる偏心モータとを備えることを特徴とする揺動運動器具である。   The present invention includes a base placed on the floor, an intermediate frame held by the base so as to be swingable in the vertical direction and / or the horizontal direction, the intermediate frame in the vertical direction with respect to the base, and / or A swing mechanism that swings in the left-right direction, a mounting portion on which a mounting surface for mounting a part or all of the body is formed on the upper surface, and an intermediate frame and the mounting portion are interposed between When the mounting portion is held at a predetermined origin position on the intermediate frame and an external force is applied to the mounting portion in a direction along the mounting surface, the mounting portion is moved in the direction of the external force with respect to the intermediate frame. A holding means for generating a biasing force that biases the mounting portion to the origin position, and an eccentric motor that is fixed to the bottom portion of the mounting portion and projects the rotating shaft downward substantially perpendicular to the mounting surface. An oscillating exercise device characterized by comprising:

かかる構成にあっては、偏心モータが駆動して、錘の遠心力が乗載面に沿った方向に発生すると、乗載部が遠心力の方向に変位して、保持手段が原点位置への付勢力を発生させる。ここで、偏心モータの錘の遠心力の方向は、錘の回転に伴って乗載面上を回転するため、偏心モータの駆動時には、偏心モータの錘の遠心力と、保持手段による原点位置方向の付勢力によって、乗載部は、中間フレームに対して、原点位置を中心に、乗載面に沿って楕円状(円状を含む)の軌跡を描くように、揺動することとなる。   In this configuration, when the eccentric motor is driven and the centrifugal force of the weight is generated in the direction along the mounting surface, the mounting portion is displaced in the direction of the centrifugal force, and the holding means is moved to the origin position. Generate a biasing force. Here, since the direction of the centrifugal force of the eccentric motor rotates on the mounting surface as the weight rotates, when the eccentric motor is driven, the centrifugal force of the eccentric motor weight and the origin position direction by the holding means Due to this urging force, the mounting portion swings with respect to the intermediate frame so as to draw an elliptical (including circular) trajectory along the mounting surface around the origin position.

このように、本発明にあっては、床に載置されるベースに対して乗載部を直接保持するのでなく、ベースに対して中間フレームを上下及び/又は左右に揺動可能に保持し、さらに、偏心モータと保持手段によって、乗載部を中間フレームに対して楕円状の軌跡で揺動可能に保持するため、クランク機構を用いることなく楕円状の揺動方向を追加できる。そして、かかる偏心モータと保持手段は、クランク機構に比べて低廉に実現可能であるため、本発明によれば、従来構成に比べて乗載部の揺動方向を低廉に増やすことができる。また、本発明に係る保持手段と偏心モータは、クランク機構よりも軽量な構成で実現可能であるため、上下及び/又は左右に揺動させる中間フレーム上に配設しても不具合は生じない。   Thus, in the present invention, the mounting portion is not directly held with respect to the base placed on the floor, but the intermediate frame is held so as to be swingable up and down and / or left and right with respect to the base. Furthermore, since the mounting portion is held by the eccentric motor and the holding means so as to be swingable with respect to the intermediate frame along an elliptical locus, an elliptical swinging direction can be added without using a crank mechanism. Since the eccentric motor and the holding means can be realized at a lower cost than the crank mechanism, according to the present invention, the swinging direction of the mounting portion can be increased at a lower cost than the conventional configuration. Moreover, since the holding means and the eccentric motor according to the present invention can be realized with a lighter configuration than the crank mechanism, there is no problem even if they are arranged on an intermediate frame that swings up and down and / or left and right.

本発明の具体的な態様として、前記保持手段は、弾性材を備えてなり、乗載部に対して乗載面に沿った方向に外力が加わると、該弾性材が弾性変形することにより、中間フレームに対して乗載部を該外力の方向に変位させるとともに、弾性材の復元弾力によって乗載部を原点位置に付勢する構成が提案される。かかる構成にあっては、ゴム等の弾性材によって、乗載部を支持しつつ、乗載面に沿った方向に乗載部を変位可能に保持できるため、従来構成に比べて、極めて低廉かつ軽量に揺動方向を増やすことができる。   As a specific aspect of the present invention, the holding means includes an elastic material, and when an external force is applied to the mounting portion in a direction along the mounting surface, the elastic material is elastically deformed, A configuration is proposed in which the mounting portion is displaced in the direction of the external force with respect to the intermediate frame, and the mounting portion is biased to the origin position by the restoring elasticity of the elastic material. In such a configuration, the mounting portion can be held so as to be displaceable in a direction along the mounting surface while supporting the mounting portion with an elastic material such as rubber. The swinging direction can be increased lightly.

また、本発明の具体的な態様として、前記保持手段は、中間フレームと乗載部のいずれか一方に配設されたボールキャスターと、中間フレームと乗載部のいずれか他方に配設されてボールキャスターを凹面上に支持する受皿とを備えてなるものであり、乗載部に対して乗載面に沿った方向に外力が加わると、ボールキャスターが受皿の凹面上を該外力の方向に転がることにより、中間フレームに対して乗載部を該外力の方向に変位させるとともに、受皿の凹面の案内作用によって乗載部を原点位置に付勢する構成も提案される。かかる構成にあっても、クランク機構を設けることなく、従来構成に比べて、低廉かつ軽量に揺動方向を増やすことができる。   Further, as a specific aspect of the present invention, the holding means is disposed on one of the intermediate frame and the mounting portion, and on one of the intermediate frame and the mounting portion. A receiving tray that supports the ball caster on the concave surface. When an external force is applied to the mounting portion in a direction along the mounting surface, the ball caster moves on the concave surface of the receiving tray in the direction of the external force. A configuration is also proposed in which the riding part is displaced in the direction of the external force with respect to the intermediate frame by rolling, and the riding part is urged to the origin position by the guiding action of the concave surface of the tray. Even in such a configuration, the swinging direction can be increased more inexpensively and lightly than the conventional configuration without providing a crank mechanism.

また、本発明にあって、偏心モータは、乗載部の重心に配設されている構成が提案される。かかる構成にあっては、偏心モータの遠心力が乗載部の重心に加わることとなるため、乗載部を自転させる方向にモーメントを発生させることなく、遠心力によって乗載部を乗載面に沿って効率的に変位させて、乗載部を円滑に揺動させることが可能となる。   In the present invention, a configuration is proposed in which the eccentric motor is disposed at the center of gravity of the mounting portion. In such a configuration, since the centrifugal force of the eccentric motor is applied to the center of gravity of the mounting portion, the mounting portion is placed by the centrifugal force without generating a moment in the direction of rotating the mounting portion. Accordingly, it is possible to smoothly displace the mounting portion and to smoothly swing the mounting portion.

また、本発明にあって、前記保持手段は、乗載部の重心を中心とする対称位置に、対をなすように複数配設されている構成が提案される。かかる構成にあっては、乗載部を原点位置に付勢する付勢力によって、乗載部を自転させる方向のモーメントが発生しないため、乗載部を一層円滑に揺動させることが可能となる。   Further, in the present invention, a configuration is proposed in which a plurality of the holding means are arranged so as to form a pair at a symmetrical position with the center of gravity of the mounting portion as the center. In such a configuration, since the moment in the direction of rotating the mounting portion is not generated by the urging force that urges the mounting portion to the origin position, the mounting portion can be more smoothly swung. .

さらに、本発明にあっては、中間フレームには開口部が形成されており、偏心モータは乗載部の底部から下方に突出して前記開口部に挿入されている構成が提案される。かかる構成にあっては、偏心モータと中間フレームとを干渉させることなく、乗載部の高さを低くすることができるため、揺動運動器具をコンパクト化できるとともに、乗載部の揺動時の安定性を向上させることが可能となる。   Furthermore, in the present invention, a configuration is proposed in which an opening is formed in the intermediate frame, and the eccentric motor protrudes downward from the bottom of the riding portion and is inserted into the opening. In such a configuration, the height of the mounting portion can be reduced without causing the eccentric motor and the intermediate frame to interfere with each other, so that the swinging exercise device can be made compact and the swinging portion can be swung. It becomes possible to improve stability.

本実施例の揺動運動器具1は、図1に示すように、上面に平坦な乗載面2形成された乗載部3を備えている。乗載部3は駆動源によって揺動可能となっており、図1に示すように乗載面2の上に足を載せて立った状態で、駆動源によって乗載部3を揺動させて、筋肉を揺らして緊張と弛緩を繰り返させることで、能動的に体を動かさなくても、筋力トレーニングや有酸素運動、筋肉のストレッチ、マッサージなどが可能となるものである。なお、かかる揺動運動器具1は、乗載面2に立った状態で使用するだけでなく、乗載面2に座った状態など、体の一部を載せた状態でも使用できる。後述するように、本実施例の揺動運動器具1は、乗載部3を上下方向、左右方向、及び円方向の3方向に揺動させる。図1に示すように、乗載面2は横長矩形状をなしており、そのサイズは、幅約80cm×奥行約50cmである。
Embodiments of the present invention are illustrated by the following examples.
As shown in FIG. 1, the swing exercise device 1 of the present embodiment includes a mounting portion 3 having a flat mounting surface 2 formed on the upper surface. The riding part 3 can be swung by a driving source, and the riding part 3 is swung by the driving source in a state where a foot is placed on the riding surface 2 as shown in FIG. By repeating the tension and relaxation by shaking the muscles, muscle training, aerobic exercise, muscle stretching, massage, etc. are possible without actively moving the body. The swing exercise device 1 can be used not only on the riding surface 2 but also on a part of the body such as sitting on the riding surface 2. As will be described later, the swing exercise device 1 of the present embodiment swings the mounting portion 3 in three directions, ie, a vertical direction, a horizontal direction, and a circular direction. As shown in FIG. 1, the mounting surface 2 has a horizontally long rectangular shape, and the size is about 80 cm wide × about 50 cm deep.

揺動運動器具1の構成について詳述すると、図1に示すように、揺動運動器具1は、前記乗載部3と、乗載部3を揺動可能に保持する運動器具本体4とで構成される。運動器具本体4は、図2,3に示すように、床に載置されるベース6と、ベース6の上に揺動可能に保持される中間フレーム7と、該中間フレーム7を揺動させる揺動機構とを備えており、乗載部3は中間フレーム7の上に保持される。   The configuration of the swing exercise device 1 will be described in detail. As shown in FIG. 1, the swing exercise device 1 includes the riding portion 3 and an exercise device body 4 that holds the mounting portion 3 so as to be swingable. Composed. As shown in FIGS. 2 and 3, the exercise equipment body 4 swings the base 6 placed on the floor, the intermediate frame 7 that is swingably held on the base 6, and the intermediate frame 7. The mounting portion 3 is held on the intermediate frame 7.

図1,2に示すように、ベース6は、上部が開放された金属箱状をなしており、その内部に、中間フレーム7を揺動させる揺動機構が配設される。ベース6の下底面には滑り止めシート9が固着され、ベース6は床Fの上に滑らないように載置される。中間フレーム7は、中央部に円形の開口部8が形成された、矩形板状の金属フレームである。ベース6と中間フレーム7の平面形状は略同大であり、中間フレーム7は、ベース6の上に重なるように保持される。   As shown in FIGS. 1 and 2, the base 6 has a metal box shape with an open top, and a swing mechanism for swinging the intermediate frame 7 is disposed therein. A non-slip sheet 9 is fixed to the lower bottom surface of the base 6, and the base 6 is placed on the floor F so as not to slip. The intermediate frame 7 is a rectangular plate-shaped metal frame in which a circular opening 8 is formed at the center. The planar shapes of the base 6 and the intermediate frame 7 are substantially the same, and the intermediate frame 7 is held so as to overlap the base 6.

図2に示すように、ベース6と中間フレーム7は、短尺なアーム10によって幅方向の中央部で相互に連結される。中間フレーム7は、その中央部をアーム10の上端部10aに軸支されることにより、シーソーのように両端部を上下方向に揺動可能としている。また、アーム10の下端部10bは、ベース6の中央部に軸支されて、上端部10aを左右に揺動可能としている。このように、中間フレーム7は、左右に揺動するアーム10の上端部10aに対して、上下に揺動可能に軸支されることにより、ベース6に対して、上下方向と左右方向の2方向に揺動可能に保持されている。そして、ベース6の内部に配設される揺動機構は、中間フレーム7をベース6に対して上下方向に揺動させる上下揺動機構と、中間フレーム7を左右方向に揺動させる左右揺動機構とで構成される。   As shown in FIG. 2, the base 6 and the intermediate frame 7 are connected to each other at the center in the width direction by a short arm 10. The intermediate frame 7 is pivotally supported by the upper end portion 10a of the arm 10 at the center, so that both end portions can be swung up and down like a seesaw. Further, the lower end portion 10b of the arm 10 is pivotally supported at the center portion of the base 6 so that the upper end portion 10a can swing left and right. In this way, the intermediate frame 7 is pivotally supported so as to be able to swing up and down with respect to the upper end portion 10a of the arm 10 swinging left and right. It is held so that it can swing in the direction. The swing mechanism disposed inside the base 6 includes a vertical swing mechanism that swings the intermediate frame 7 in the vertical direction with respect to the base 6 and a left-right swing mechanism that swings the intermediate frame 7 in the left-right direction. It consists of a mechanism.

図2に示すように、上下揺動機構は、中間フレーム7を上下に揺動させる駆動源である上下揺動用モータ14と、上下揺動用モータ14の回転を、中間フレーム7を上下に揺動させる動きに変換する上下揺動用クランク機構15とで構成される。詳述すると、上下揺動用モータ14は、ベース6の内部に固定されており、上下揺動用クランク機構15は、上下揺動用モータ14の回転運動を上下方向の往復運動に替えて、中間フレーム7の左側部を、ベース6の左側部に対して離近するように往復移動させ、これにより、中間フレーム7を、アーム10の上端部10aを中心に上下方向にシーソー状に揺動させる。なお、揺動運動器具1に配設される各種モータには、外部電源(図示省略)から電力が供給される。   As shown in FIG. 2, the vertical swing mechanism swings the intermediate frame 7 up and down by rotating the vertical swing motor 14 which is a drive source for swinging the intermediate frame 7 up and down and the vertical swing motor 14. And a vertically swinging crank mechanism 15 that converts the motion to be moved. More specifically, the vertically swinging motor 14 is fixed inside the base 6, and the vertically swinging crank mechanism 15 replaces the rotational motion of the vertically swinging motor 14 with the reciprocating motion in the vertical direction, thereby changing the intermediate frame 7. The left side portion of the arm 6 is reciprocated so as to be close to the left side portion of the base 6, thereby swinging the intermediate frame 7 in a seesaw shape in the vertical direction around the upper end portion 10 a of the arm 10. Note that power is supplied from an external power source (not shown) to the various motors disposed in the swing exercise device 1.

図2に示すように、左右揺動機構は、中間フレーム7を左右に揺動させる駆動源である左右揺動用モータ17と、左右揺動用モータ17の回転を、中間フレーム7を左右に揺動させる動きに変換する左右揺動用クランク機構18とで構成される。詳述すると、左右揺動用モータ17は、ベース6の内部に固定されており、左右揺動用クランク機構18は、左右揺動用モータ17の回転運動を左右方向の往復運動に替えて、中間フレーム7の幅方向の中央部を、左右方向に往復移動させ、これにより、中間フレーム7を、アーム10の下端部10bを中心に左右方向に揺動させる。   As shown in FIG. 2, the left / right swing mechanism swings the left / right swing motor 17, which is a drive source for swinging the intermediate frame 7 left and right, and the left / right swing motor 17, swinging the intermediate frame 7 left and right. And a left-right swinging crank mechanism 18 that converts the motion to be moved. More specifically, the left / right swing motor 17 is fixed inside the base 6, and the left / right swing crank mechanism 18 replaces the rotational motion of the left / right swing motor 17 with a reciprocating motion in the left / right direction, thereby changing the intermediate frame 7. The center portion in the width direction of the arm 10 is reciprocated in the left-right direction, whereby the intermediate frame 7 is swung in the left-right direction around the lower end portion 10 b of the arm 10.

乗載部3は、図3に示すように、矩形状の金属板からなるものであり、体を載せる乗載面2を形成する乗載部3の上面には、滑り止め加工(図示省略)が施されている。乗載部3は、中間フレーム7と乗載部3の間に介装された弾性材20によって、中間フレーム7の上の所定の原点位置に保持される。具体的には、弾性材20は、外力によって弾性変形し易い円柱状のゴムブッシュであり、中間フレーム7の上面にあって、右手前、右奥、左手前、左奥の4箇所に1個ずつ固着される。4個の弾性材20の形状及び材質は共通しており、中間フレーム7の重心を中心に、右手前と左奥で対をなすように、また、左手前と右奥で対をなすように対称配置される。そして、乗載部3は、その底面を、四個の弾性材20の上面に固着することによって原点位置に保持される。かかる原点位置は、乗載部3が、中間フレーム7と平行となり、かつ、乗載部3の重心と中間フレーム7の重心が上下に重なることとなる位置である。このように、乗載部3は、弾性材20によって原点位置に保持されているため、乗載部3に対して乗載面2に沿った方向に外力を加えて弾性材20を弾性変形させることにより、中間フレーム7に対して乗載部3を外力方向に変位させることができ、また、弾性材20の復元弾力によって乗載部3を原点位置に付勢する付勢力を発生させることができる。   As shown in FIG. 3, the mounting portion 3 is made of a rectangular metal plate, and the upper surface of the mounting portion 3 that forms the mounting surface 2 on which the body is placed has an anti-slip process (not shown). Is given. The mounting portion 3 is held at a predetermined origin position on the intermediate frame 7 by an elastic material 20 interposed between the intermediate frame 7 and the mounting portion 3. Specifically, the elastic member 20 is a cylindrical rubber bush that is easily elastically deformed by an external force. The elastic member 20 is on the upper surface of the intermediate frame 7, and is one piece at four locations on the right front, right back, left front, and left back. It is fixed one by one. The shape and material of the four elastic members 20 are the same, so that the middle frame 7 is centered on the center of gravity so that a pair is formed at the right front and back left, and a pair is formed at the left front and right back Symmetrical arrangement. And the mounting part 3 is hold | maintained in an origin position by adhering the bottom face to the upper surface of the four elastic materials 20. FIG. The origin position is a position where the mounting portion 3 is parallel to the intermediate frame 7 and the center of gravity of the mounting portion 3 and the center of gravity of the intermediate frame 7 overlap each other. Thus, since the mounting portion 3 is held at the origin position by the elastic material 20, an external force is applied to the mounting portion 3 in the direction along the mounting surface 2 to elastically deform the elastic material 20. Thus, the mounting portion 3 can be displaced in the direction of the external force with respect to the intermediate frame 7, and the urging force that urges the mounting portion 3 to the origin position can be generated by the restoring elasticity of the elastic material 20. it can.

図2〜5に示すように、乗載部3の底部には偏心モータ21が配設される。偏心モータ21は、モータの回転軸23に偏りのある態様で錘22を固定してなるものである。この偏心モータ21は、その回転軸23が乗載面2に対して垂直に下方突出するようにして、乗載部3の底面の重心位置に固着される。また、図5に示すように、乗載部3の底部から下方に突出するように配設された偏心モータ21は、中間フレーム7の中央部に形成された開口部8を貫通して、中間フレーム7の下方まで突出している。   As shown in FIGS. 2 to 5, an eccentric motor 21 is disposed at the bottom of the mounting portion 3. The eccentric motor 21 is formed by fixing a weight 22 in such a manner that the rotating shaft 23 of the motor is biased. The eccentric motor 21 is fixed to the position of the center of gravity of the bottom surface of the mounting portion 3 so that the rotation shaft 23 protrudes vertically downward with respect to the mounting surface 2. Further, as shown in FIG. 5, the eccentric motor 21 disposed so as to protrude downward from the bottom portion of the mounting portion 3 passes through the opening portion 8 formed in the central portion of the intermediate frame 7, Projects to the bottom of the frame 7.

本実施例にあっては、偏心モータ21を駆動させることにより、乗載部3を、中間フレーム7に対して乗載面2に沿って円を描くように揺動させることができる。具体的には、偏心モータ21を駆動させると、錘22の遠心力が乗載面2に沿って発生する。そして、この遠心力が、偏心モータ21が固着された乗載部3の重心に加わることにより、図5に示すように、乗載部3を保持する弾性材20が弾性変形して、乗載部3は、遠心力の方向に変位し、また、弾性材20の復元弾力によって原点位置に付勢される。   In the present embodiment, by driving the eccentric motor 21, the mounting portion 3 can be swung so as to draw a circle along the mounting surface 2 with respect to the intermediate frame 7. Specifically, when the eccentric motor 21 is driven, a centrifugal force of the weight 22 is generated along the mounting surface 2. And this elastic force is added to the gravity center of the mounting part 3 to which the eccentric motor 21 is fixed, so that the elastic member 20 holding the mounting part 3 is elastically deformed as shown in FIG. The part 3 is displaced in the direction of the centrifugal force, and is urged to the origin position by the restoring elasticity of the elastic member 20.

ここで、偏心モータ21から乗載部3に加わる遠心力の方向は、錘22の回転に合わせて乗載面2に沿って回転することとなる。このため、本実施例では、偏心モータ21の駆動時には、偏心モータ21の錘22の遠心力と、弾性材20の復元弾力によって、乗載部3は、図6に示すように、原点位置を中心に、乗載面2に沿って円を描くように揺動することとなる。なお、偏心モータ21の錘22の遠心力は乗載部3に加わり、また、乗載部3は重心を中心とする対称位置で弾性材20に保持されているため、かかる乗載部3の揺動時に、乗載部3が乗載面2に沿って自転することは殆どない。また、中間フレーム7の開口部8は、偏心モータ21が乗載部3の揺動に伴って開口部8の内部で揺動しても、偏心モータ21が開口縁とぶつからないような大きさに形成されている。   Here, the direction of the centrifugal force applied from the eccentric motor 21 to the mounting portion 3 rotates along the mounting surface 2 in accordance with the rotation of the weight 22. For this reason, in the present embodiment, when the eccentric motor 21 is driven, the mounting portion 3 sets the origin position by the centrifugal force of the weight 22 of the eccentric motor 21 and the restoring elasticity of the elastic member 20, as shown in FIG. At the center, it swings so as to draw a circle along the mounting surface 2. It should be noted that the centrifugal force of the weight 22 of the eccentric motor 21 is applied to the mounting portion 3, and the mounting portion 3 is held by the elastic material 20 at a symmetrical position with the center of gravity as the center. When swinging, the mounting portion 3 hardly rotates along the mounting surface 2. Further, the opening 8 of the intermediate frame 7 is sized so that the eccentric motor 21 does not collide with the opening edge even if the eccentric motor 21 swings inside the opening 8 as the mounting portion 3 swings. Is formed.

このように、本実施例の揺動運動器具1は、上下揺動用モータ14の駆動によって、中間フレーム7を上下に揺動させることができ、また、左右揺動用モータ17の駆動によって中間フレーム7を左右に揺動させることができ、さらに、偏心モータ21の駆動によって、乗載部3を自転させることなく円を描くように揺動させることができる。ここで、揺動運動器具1のベース6の内部には、上下揺動用モータ14、左右揺動用モータ17、及び偏心モータ21の駆動を制御する制御基板(図示省略)が設けられており、図示しない遠隔操作装置(リモコン)によって、使用者が各モータ14,17,21のON/OFFと回転速度を調整できるよう構成されている。   As described above, the swing exercise device 1 of this embodiment can swing the intermediate frame 7 up and down by driving the vertical swing motor 14, and can drive the intermediate frame 7 by driving the left and right swing motor 17. Can be swung left and right, and further, by driving the eccentric motor 21, it can be swung in a circle without rotating the mounting portion 3. Here, inside the base 6 of the swing exercise device 1, a control board (not shown) for controlling driving of the vertical swing motor 14, the left and right swing motor 17, and the eccentric motor 21 is provided. The remote control device (remote control) that is not used allows the user to adjust the ON / OFF and rotation speed of each motor 14, 17, 21.

したがって、本実施例の揺動運動器具1は、使用者が体の一部又は全部を乗載面2に載せた状態で、3つのモータ14,17,21を同時に駆動させれば、乗載面2を、上下方向、左右方向、円方向の3方向に同時に揺動させて、筋肉を3方向にムラなく振動させることできる。このように、筋肉を振動させる方向を増大させれば、短時間で筋肉を効率良く運動させることができ、また、筋肉に局所的な負荷が集中し難いため、長時間の有酸素運動にも適する。   Therefore, the swing exercise device 1 of the present embodiment is mounted when the user drives the three motors 14, 17, 21 at the same time in a state where a part or all of the body is mounted on the mounting surface 2. The surface 2 can be swung simultaneously in the three directions of the vertical direction, the horizontal direction, and the circular direction, and the muscles can be vibrated in three directions without unevenness. In this way, if the direction in which the muscles are vibrated is increased, the muscles can be exercised efficiently in a short time, and the local load is difficult to concentrate on the muscles. Suitable.

本実施例では、クランク機構によって揺動可能に保持された中間フレーム7の上に弾性材20を介して乗載部3を保持して、偏心モータ21の錘22の遠心力によって弾性材20を弾性変形させることで、円を描くように乗載部3を揺動させるため、クランク機構等を設けることなく、比較的低廉な構成によって、乗載部3に、さらなる揺動方向を追加できるという利点がある。なお、弾性材20及び偏心モータ21は、中間フレーム7を上下左右に揺動させる揺動機構に比べて軽量であるため、上下左右に揺動する中間フレーム7の上に配設しても不具合は生じない。   In the present embodiment, the mounting portion 3 is held via the elastic material 20 on the intermediate frame 7 that is swingably held by the crank mechanism, and the elastic material 20 is moved by the centrifugal force of the weight 22 of the eccentric motor 21. Since the mounting portion 3 is swung like a circle by elastic deformation, a further swinging direction can be added to the mounting portion 3 with a relatively inexpensive configuration without providing a crank mechanism or the like. There are advantages. The elastic member 20 and the eccentric motor 21 are lighter than a swing mechanism that swings the intermediate frame 7 up and down and left and right, so that even if the elastic member 20 and the eccentric motor 21 are disposed on the intermediate frame 7 that swings up and down and left and right Does not occur.

また、本実施例では、乗載部3の重心に配設された偏心モータ21の錘22の遠心力が乗載部3の重心に加わるため、乗載部3を自転させる方向にモーメントを発生させることなく、遠心力によって乗載部3を乗載面2に沿って効率的に変位させて、乗載部3を円滑に揺動させられるという利点がある。   In this embodiment, since the centrifugal force of the weight 22 of the eccentric motor 21 disposed at the center of gravity of the mounting part 3 is applied to the center of gravity of the mounting part 3, a moment is generated in the direction of rotating the mounting part 3. Without this, there is an advantage that the mounting portion 3 can be efficiently displaced along the mounting surface 2 by centrifugal force, and the mounting portion 3 can be smoothly swung.

また、本実施例では、4個の弾性材20が、乗載部3の重心を中心とする対称位置に、対をなすように配設されているため、乗載部3が原点位置から変位したときに、弾性材20の復元弾力によって、乗載部3を自転させる方向のモーメントが発生しない。このため、かかる構成によれば、乗載部3を乗載面2に沿って殆ど自転させずに、円を描くように円滑に揺動させられるという利点がある。   In the present embodiment, the four elastic members 20 are disposed so as to form a pair at symmetrical positions with the center of gravity of the mounting portion 3 as the center, so that the mounting portion 3 is displaced from the origin position. In this case, the moment in the direction of rotating the mounting portion 3 is not generated by the restoring elasticity of the elastic member 20. For this reason, according to this configuration, there is an advantage that the mounting portion 3 can be smoothly swung in a circle without substantially rotating along the mounting surface 2.

また、本実施例では、乗載部3の底部の偏心モータ21が、中間フレーム7の開口部8を貫通して中間フレーム7の下方に突出するよう構成している。かかる構成によれば、中間フレーム7と乗載部3の間隔を狭くして乗載部3の高さを抑えることができるため、揺動運動器具1のコンパクト化や、乗載部3の揺動時の安定性向上が可能となる。   In the present embodiment, the eccentric motor 21 at the bottom of the mounting portion 3 is configured to pass through the opening 8 of the intermediate frame 7 and protrude below the intermediate frame 7. According to such a configuration, the distance between the intermediate frame 7 and the mounting portion 3 can be narrowed and the height of the mounting portion 3 can be suppressed, so that the swing exercise device 1 can be made compact and the mounting portion 3 can be swung. The stability during operation can be improved.

なお、本発明は、上記実施例の構成に限定されるものではなく、本発明の要旨を逸脱しない範囲内で適宜変更可能である。例えば、上記実施例では、中間フレーム7は、上下方向と左右方向の2方向に揺動可能となっているが、本発明に係る中間フレームの揺動方向は1方向でも構わない。また、中間フレームは、上下及び/又は左右方向に加えて、前後方向に揺動させてもよい。   In addition, this invention is not limited to the structure of the said Example, In the range which does not deviate from the summary of this invention, it can change suitably. For example, in the above embodiment, the intermediate frame 7 can swing in two directions, ie, the vertical direction and the horizontal direction, but the swing direction of the intermediate frame according to the present invention may be one direction. Further, the intermediate frame may be swung in the front-rear direction in addition to the up-down direction and / or the left-right direction.

また、上記実施例では、乗載部3を4個の弾性材20によって保持しているが、弾性材20の配設数は適宜変更可能である。また、上記実施例では、偏心モータ21の錘22の遠心力によって乗載部3が中間フレーム7に対して円状の軌跡を描くように揺動するが、乗載部3の軌跡は円状に限らず、楕円状であってもかまわない。   Moreover, in the said Example, although the mounting part 3 is hold | maintained with the four elastic materials 20, the arrangement | positioning number of the elastic materials 20 can be changed suitably. In the above-described embodiment, the mounting portion 3 swings so as to draw a circular locus with respect to the intermediate frame 7 by the centrifugal force of the weight 22 of the eccentric motor 21, but the locus of the mounting portion 3 is circular. Not limited to this, it may be oval.

また、上記実施例では、本発明に係る保持手段を弾性材(ゴムブッシュ)20のみによって構成しているが、本発明に係る保持手段は、かかる弾性材に限定されず、乗載部を原点位置に保持し、乗載部に対して乗載面に沿った方向に外力が加わると、乗載部を外力の方向に変位させるとともに、乗載部を原点位置に付勢する付勢力を発生させるものであればよい。   Moreover, in the said Example, although the holding means which concerns on this invention is comprised only by the elastic material (rubber bush) 20, the holding means which concerns on this invention is not limited to this elastic material, A mounting part is made into an origin. When an external force is applied to the mounting portion in the direction along the mounting surface, the mounting portion is displaced in the direction of the external force and a biasing force that biases the mounting portion to the origin position is generated. Anything can be used.

例えば、図7は、本発明に係る保持手段を、ゴム製の弾性材20に替えて、スペーサ24とコイルバネ25によって構成した変形例の揺動運動器具1aである。具体的には、本変形例では、中間フレーム7と乗載部3の間に円柱状の金属製スペーサ24が複数介装され、金属製スペーサ24の上端によって乗載部3を中間フレーム7と平行となるよう支持する。ここで、スペーサ24は、下端を中間フレーム7の上面に固着されるが、その上端は乗載部3の底面に固着されず、乗載部3の底面が、スペーサ24の上を滑ることによって、原点位置から乗載面2に沿った方向に変位可能となっている。   For example, FIG. 7 shows a swing exercise device 1a of a modified example in which the holding means according to the present invention is configured by a spacer 24 and a coil spring 25 in place of the rubber elastic material 20. Specifically, in this modification, a plurality of cylindrical metal spacers 24 are interposed between the intermediate frame 7 and the mounting portion 3, and the mounting portion 3 is connected to the intermediate frame 7 by the upper end of the metal spacer 24. Support to be parallel. Here, the lower end of the spacer 24 is fixed to the upper surface of the intermediate frame 7, but the upper end is not fixed to the bottom surface of the mounting portion 3, and the bottom surface of the mounting portion 3 slides on the spacer 24. The position can be displaced in the direction along the mounting surface 2 from the origin position.

さらに、本変形例では、中間フレーム7と乗載部3の間にコイルバネ25が複数介装される。具体的には、コイルバネ25は、上端が乗載部3の底面に固着され、下端が中間フレーム7の上面に固着されることにより、乗載部3が原点位置から乗載面2に沿った方向に変位した時に、コイルバネ25の復元弾力によって、乗載部3を原点位置方向に付勢する。   Furthermore, in this modification, a plurality of coil springs 25 are interposed between the intermediate frame 7 and the mounting portion 3. Specifically, the upper end of the coil spring 25 is fixed to the bottom surface of the mounting portion 3, and the lower end is fixed to the upper surface of the intermediate frame 7, so that the mounting portion 3 extends along the mounting surface 2 from the origin position. When displaced in the direction, the mounting portion 3 is urged toward the origin position by the restoring elasticity of the coil spring 25.

したがって、かかる構成にあっても、偏心モータ21の駆動によって、乗載部3に対して乗載面2に沿った方向に錘22の遠心力が加わると、乗載部3は、原点位置から変位して、偏心モータ21の錘22の遠心力と、コイルバネ25の復元弾力によって、中間フレーム7に対して乗載面2に沿って円状又は楕円状の軌跡を描くように揺動することとなる。このように、本発明に係る保持手段は、弾性材のみに限らず、弾性材とスペーサの組合せにより構成してもよい。   Therefore, even in such a configuration, when the centrifugal force of the weight 22 is applied to the mounting portion 3 in the direction along the mounting surface 2 by driving the eccentric motor 21, the mounting portion 3 is moved from the origin position. Displacement and rocking so as to draw a circular or elliptical locus along the mounting surface 2 with respect to the intermediate frame 7 by the centrifugal force of the weight 22 of the eccentric motor 21 and the restoring elasticity of the coil spring 25. It becomes. Thus, the holding means according to the present invention is not limited to an elastic material, and may be configured by a combination of an elastic material and a spacer.

また、図8は、本発明に係る保持手段を、ゴム製の弾性材20に替えて、ボールキャスター26と受皿27で構成した変形例の揺動運動器具1bである。具体的には、本変形例では、乗載部3の底面にボールキャスター26が複数固着されるとともに、中間フレーム7の上面にあって、各ボールキャスター26と上下に対向する位置に受皿27が夫々固着される。受皿27は、球面状の凹面28を有する金属部材であり、その凹面28は、中央部が最も深く、中央部から外周部に向かうにつれて傾斜がきつくなるよう形成されている。ボールキャスター26と受皿27は、乗載部3が原点位置に位置する時に、ボールキャスター26が受皿27の凹面28の中央部に支持されるように配置されている。かかる構成にあっては、乗載部3に対して乗載面2に沿った方向に錘22の遠心力が加わると、ボールキャスター26が受皿27の凹面28の上を遠心力の方向に転がることにより、中間フレーム7に対して乗載部3を遠心力の方向に変位させるとともに、受皿27の凹面28の案内作用によって乗載部3を原点位置に付勢する付勢力が発生する。また、乗載部3が原点位置から大きく変位するほど、凹面28の、ボールキャスター26を支持する部分の傾斜がきつくなることで、乗載部3を原点位置に付勢する付勢力が強くなる。   FIG. 8 shows a swinging exercise apparatus 1b of a modified example in which the holding means according to the present invention is configured by a ball caster 26 and a receiving tray 27 in place of the rubber elastic material 20. Specifically, in the present modification, a plurality of ball casters 26 are fixed to the bottom surface of the mounting portion 3, and a tray 27 is provided at a position on the top surface of the intermediate frame 7 so as to face each ball caster 26 vertically. Each is fixed. The saucer 27 is a metal member having a spherical concave surface 28, and the concave surface 28 is formed so that the central portion is deepest and the inclination becomes tighter from the central portion toward the outer peripheral portion. The ball caster 26 and the receiving tray 27 are arranged so that the ball caster 26 is supported by the central portion of the concave surface 28 of the receiving tray 27 when the mounting portion 3 is located at the origin position. In this configuration, when the centrifugal force of the weight 22 is applied to the mounting portion 3 in the direction along the mounting surface 2, the ball caster 26 rolls on the concave surface 28 of the tray 27 in the direction of the centrifugal force. As a result, the mounting portion 3 is displaced in the direction of the centrifugal force with respect to the intermediate frame 7, and a biasing force that biases the mounting portion 3 to the origin position is generated by the guiding action of the concave surface 28 of the tray 27. Further, the greater the displacement of the mounting portion 3 from the origin position, the stronger the inclination of the concave portion 28 that supports the ball caster 26, thereby increasing the urging force that urges the mounting portion 3 to the origin position. .

このように、本変形例にあっては、ボールキャスター26と受皿27が、乗載部3を原点位置に保持し、乗載部3に対して乗載面2に沿った方向に外力が加わると、乗載部3を外力の方向に変位させるとともに、乗載部3を原点位置に付勢する付勢力を発生させる。このため、本変形例にあっても、偏心モータ21の駆動によって、乗載部3に対して乗載面2に沿った方向に錘22の遠心力が加わると、乗載部3は、原点位置から変位して、錘22の遠心力と原点位置への付勢力によって、中間フレーム7に対して原点位置を中心に乗載面2に沿って円状又は楕円状の軌跡を描くように揺動することとなる。このように、本発明に係る保持手段は、ボールキャスターと受皿の組合せにより構成することも可能である。   Thus, in this modification, the ball caster 26 and the tray 27 hold the mounting portion 3 at the origin position, and external force is applied to the mounting portion 3 in the direction along the mounting surface 2. Then, the mounting portion 3 is displaced in the direction of the external force, and a biasing force that biases the mounting portion 3 to the origin position is generated. For this reason, even in this modification, when the eccentric motor 21 is driven and the centrifugal force of the weight 22 is applied to the mounting portion 3 in the direction along the mounting surface 2, the mounting portion 3 becomes the origin. Due to the displacement from the position and the urging force to the origin position by the centrifugal force of the weight 22, the intermediate frame 7 is swung so as to draw a circular or elliptical locus along the mounting surface 2 around the origin position. Will move. Thus, the holding means according to the present invention can be configured by a combination of a ball caster and a tray.
