Description

本発明は、膝まわりの筋肉を鍛えられるトレーニングマシンに関する。   The present invention relates to a training machine that can train muscles around the knee.

膝の曲げ伸ばしがスムーズに行われないと膝に痛みが生じるが、このような膝の痛みを和らげるには、膝まわりの筋力を鍛えて関節への負担を減らしたり、ストレッチで関節の動きを柔らかくしたりするのが良いとされている。そこで、膝まわりの筋力を鍛えるための種々のトレーニングマシンが提案されており、このようなトレーニングマシンとしては、例えば自転車のペダルを漕ぐような運動を行う自転車型のものや(例えば、特許文献1参照)、階段の昇り降りを繰り返すような運動を続けるステッピングマシン(例えば、特許文献2参照)が挙げられる。   If the knees are not bent and stretched smoothly, pain may occur in the knees. It is said to be soft. Accordingly, various training machines for training the muscle strength around the knee have been proposed. Examples of such a training machine include a bicycle type that performs exercises such as pedaling a bicycle (for example, Patent Document 1). And a stepping machine (see, for example, Patent Document 2) that continues to move up and down the stairs repeatedly.

特開第2000−116818号公報JP 2000-116818 A 特開第2006−102431号公報JP 2006-104311 A

ここで、膝を伸ばすと半月板は前方へ移動すると共に下腿が内旋し(頸骨内旋運動)、膝を曲げると半月板は後方へ移動すると共に下腿が外旋する(頸骨外旋運動)。すなわち、膝の屈伸運動(伸展運動及び屈曲運動)に膝の旋回運動が加わることで、膝の曲げ伸ばしがスムーズに行われる。   When the knee is extended, the meniscus moves forward and the lower leg rotates inward (tibial internal rotation). When the knee is bent, the meniscus moves backward and the lower leg rotates externally (tibial external rotation). . That is, the knee flexion / extension motion (extension motion and flexion motion) is added to the knee turning motion, so that the knee is smoothly bent and stretched.

よって、筋力の衰えにより膝の曲げ伸ばしがスムーズにできない場合には、膝を屈伸させるための筋力だけでなく、膝(半月板)を旋回させるための筋力を鍛えるのが好ましい。しかしながら、従来のトレーニングマシンは膝の屈伸運動にのみ着目しており、膝の旋回運動に着目したものはなかった。   Therefore, when the knee cannot be smoothly bent and stretched due to the weakening of the muscle strength, it is preferable to train not only the muscle strength for bending and stretching the knee but also the muscle strength for turning the knee (meniscus). However, conventional training machines focus only on knee flexion and extension, and none focus on knee turning motion.

本発明は、膝を旋回させるための筋力を鍛えることのできるトレーニングマシンの提供を目的とする。   An object of this invention is to provide the training machine which can train the muscular strength for turning a knee.

本発明の請求項1に記載のトレーニングマシンは、使用者の両足が載置される載置台と、 前記載置台に支持された支柱と、前記支柱に支持され、前記使用者が把持してパドリング動作を行うためのハンドルと、を備え、前記支柱は、上下方向に延びる第1回転軸を中心に前記載置台に対して回転自在とされ、前記ハンドルは、前記ハンドルの長手方向中心に位置する第2回転軸を中心に前記支柱に対して回転自在とされ、前記第2回転軸は前記第1回転軸に対して垂直に延びていることを特徴とする。   The training machine according to claim 1 of the present invention is a mounting table on which both feet of a user are mounted; a support supported by the mounting table; and a support supported by the support, which is gripped and paddled by the user. A handle for performing an operation, wherein the support column is rotatable with respect to the mounting table about a first rotation axis extending in a vertical direction, and the handle is positioned at a longitudinal center of the handle. The second rotation axis is rotatable about the second rotation axis, and the second rotation axis extends perpendicularly to the first rotation axis.

本発明の請求項2に記載のトレーニングマシンは、前記第1回転軸の軸線は、前記第2回転軸と交差することを特徴とする。   The training machine according to claim 2 of the present invention is characterized in that an axis of the first rotation axis intersects with the second rotation axis.

本発明の請求項3に記載のトレーニングマシンは、前記ハンドルの長手方向両側には重りが着脱自在に装着されることを特徴とする。   The training machine according to claim 3 of the present invention is characterized in that weights are detachably attached to both sides in the longitudinal direction of the handle.

本発明の請求項1に記載のトレーニングマシンによれば、支柱は第1回転軸を中心に回転自在であり、ハンドル部は第2回転軸を中心に回転自在であるから、使用者がハンドル部を把持してパドリング動作を行うと、ハンドルは前後方向に旋回すると同時に上下方向に旋回することになり、ハンドルの左右両端がそれぞれ円を描くような動きになる。そして、ハンドルの前後方向への旋回に伴い使用者の膝は捻ねられるので、膝まわりの筋肉をほぐすことができる。また、ハンドルを前後方向へ旋回させることによってハンドルには水平方向の遠心力が働くが、使用者は当該遠心力に抗してパドリング動作を行うことになるので、膝の旋回運動に必要な膝回りの筋力を鍛えることができる。更に、ハンドルは単に前後方向への旋回だけでなく、これに上下方向の旋回が加わった円を描くような動きになるので、ハンドル操作、ひいては膝の動きをスムーズに行うことができる。   According to the training machine of the first aspect of the present invention, the support column is rotatable about the first rotation axis, and the handle portion is rotatable about the second rotation axis. When a paddling operation is performed while holding the handle, the handle turns in the front-rear direction and simultaneously in the up-down direction, and the left and right ends of the handle move in a circle. Since the user's knee is twisted as the handle turns in the front-rear direction, the muscles around the knee can be loosened. In addition, by rotating the handle in the front-rear direction, a horizontal centrifugal force acts on the handle. However, since the user performs paddling operation against the centrifugal force, the knee necessary for the knee turning motion is required. You can train your strength. Furthermore, since the handle moves not only in the front-rear direction but also in a circle in which a vertical turn is added to the handle, the handle operation and thus the knee movement can be performed smoothly.

本発明の請求項2に記載のトレーニングマシンによれば、第1回転軸の軸線は第2回転軸と交差するので、第1回転軸の軸線と第2回転軸の交点を中心にハンドルが上下及び前後に旋回することになり、使用者はパドリング動作を安定して行うことができる。   According to the training machine of the second aspect of the present invention, since the axis of the first rotation axis intersects with the second rotation axis, the handle moves up and down around the intersection of the axis of the first rotation axis and the second rotation axis. Further, the user can turn back and forth, and the user can stably perform the paddling operation.

本発明の請求項3に記載のトレーニングマシンによれば、ハンドルの長手方向両側には重りが着脱自在に装着されるので、重りの有無により遠心力の大きさを調節することができ、これにより膝まわりの筋力への負荷を調節できる。また、重りを追加しても、これにより増大するのは遠心力のみであり、鉛直方向への負荷は支柱により支えられるので、膝に負担がかかることはない。   According to the training machine of the third aspect of the present invention, since the weight is detachably attached to both sides in the longitudinal direction of the handle, the magnitude of the centrifugal force can be adjusted depending on the presence or absence of the weight. The load on the muscle strength around the knee can be adjusted. Even if the weight is added, only the centrifugal force is increased by this, and the load in the vertical direction is supported by the support column, so that the knee is not burdened.

以下、添付図面を参照して、本発明の実施形態に係るトレーニングマシンについて説明する。図1〜図4を参照して、トレーニングマシン1は、使用者Mの両足Fが載置される載置台2と、載置台2に立設された支柱3と、支柱3に支持されたハンドル部4と、を備える。   Hereinafter, a training machine according to an embodiment of the present invention will be described with reference to the accompanying drawings. 1 to 4, the training machine 1 includes a mounting table 2 on which both feet F of the user M are mounted, a support column 3 standing on the mounting table 2, and a handle supported by the support column 3. Part 4.

載置台2は平坦な上面21を有し、上面21の略中央部には軸部材5が立設されている。支柱3は、軸部材5に回転自在に支持された筒状部31と、筒状部31の外周面から上方に延びる支柱本体32と、を備え、筒状部31が支柱本体32と一体的に軸部材5に対して回転することにより、支柱3が上下方向に延びる第1回転軸R1を中心に載置台2に対して回転するように構成されている。なお、支柱本体32は高さ調整可能に構成されている。   The mounting table 2 has a flat upper surface 21, and a shaft member 5 is erected at a substantially central portion of the upper surface 21. The column 3 includes a cylindrical portion 31 that is rotatably supported by the shaft member 5, and a column main body 32 that extends upward from the outer peripheral surface of the cylindrical portion 31, and the cylindrical portion 31 is integrated with the column main body 32. The column 3 is configured to rotate with respect to the mounting table 2 around the first rotation axis R1 extending in the vertical direction by rotating with respect to the shaft member 5. In addition, the support | pillar main body 32 is comprised so that height adjustment is possible.

ハンドル部4は、左右方向に延びる棒状のハンドル41と、ハンドル41の長手方向中心部から前方へ延びる軸部材42と、を備え、軸部材42は支柱本体32の上端に設けられた軸孔33に挿通されて回転自在に支持されている。よって、ハンドル部4は支柱3に対して前後方向に延びる第2回転軸R2を中心に上下方向へ旋回可能であり、また支柱3と共に第1回転軸R1を中心に前後方向へも旋回可能とされている。   The handle portion 4 includes a rod-like handle 41 extending in the left-right direction and a shaft member 42 extending forward from the longitudinal center of the handle 41. The shaft member 42 is a shaft hole 33 provided at the upper end of the column main body 32. And is rotatably supported. Therefore, the handle portion 4 can pivot in the vertical direction about the second rotation axis R2 extending in the front-rear direction with respect to the column 3, and can also pivot in the front-rear direction together with the column 3 about the first rotation axis R1. Has been.

なお、本実施形態においては、第1回転軸R1と、第2回転軸R2と、軸部材42の長手方向中心線C1とは、一点(点P)で交わるように構成されている。よって、ハンドル部4は点Pを中心に前後方向及び上下方向へ旋回自在となる。   In the present embodiment, the first rotation axis R1, the second rotation axis R2, and the longitudinal center line C1 of the shaft member 42 are configured to intersect at one point (point P). Therefore, the handle portion 4 can turn in the front-rear direction and the up-down direction around the point P.

また、ハンドル41には円筒状の一対の弾性体6a,6bが装着され、これら弾性体6a、6bの左右両側には重り7が着脱自在に装着され、ハンドル41の左右両端部位が使用者Mにより把持される把持部41aとして機能する。   A pair of cylindrical elastic bodies 6a and 6b is attached to the handle 41, and weights 7 are detachably attached to the left and right sides of the elastic bodies 6a and 6b. It functions as a gripping part 41a gripped by.

このように構成されたトレーニングマシン1は、次の様にして用いられる。まず、使用者Mは、両足Fを載置台2の上面21に載置する。このとき、両足Fは第1旋回軸R1(軸部材5)の左右両側に位置させ、足幅は小さくしておく。次に、ハンドル41が腹部くらいの高さになるよう、必要に応じて支柱3の高さ調節を行う。   The training machine 1 configured as described above is used as follows. First, the user M places both feet F on the upper surface 21 of the placing table 2. At this time, both feet F are positioned on the left and right sides of the first turning axis R1 (shaft member 5), and the foot width is kept small. Next, the height of the column 3 is adjusted as necessary so that the handle 41 is as high as the abdomen.

そして、使用者Mはハンドル41の把持部41aを把持し、パドリング動作を行う(図5〜図7参照)。即ち、ハンドル41を握ったまま、犬かき動作やカヌーのパドリング動作のように、円を描くように両手を回す。上述したように、ハンドル41は点Pを中心に前後方向及び上下方向へ旋回自在であるから、使用者Mがこのようにしてパドリング動作を行うと、ハンドル41は前後方向に旋回すると同時に上下方向に旋回することになり、ハンドル41の左右両端がそれぞれ円を描くような動きになる。即ち、ハンドル41の一端が所定方向に回転すると、ハンドル41の他端は半周遅れて同一方向に回転するようになる。   Then, the user M grips the grip 41a of the handle 41 and performs a paddling operation (see FIGS. 5 to 7). That is, while holding the handle 41, both hands are rotated so as to draw a circle like a dog shoveling action or a canoe paddling action. As described above, since the handle 41 can turn in the front-rear direction and the up-down direction about the point P, when the user M performs the paddling operation in this way, the handle 41 turns in the front-rear direction and at the same time the up-down direction. The left and right ends of the handle 41 move in a circle. That is, when one end of the handle 41 is rotated in a predetermined direction, the other end of the handle 41 is rotated in the same direction with a half turn delay.

すると、このようなハンドル41の動きに追随して、使用者Mの身体は8の字を描くように揺動し、このような身体の揺動を支えるために使用者Mの膝まわりの筋肉は水平方向に捻られるように(水平方向に旋回するように)なり、これによって膝まわりの筋肉をほぐすことができる。なお、弾性体6a,6bは揺動する使用者Mの腹部がハンドル41に直接ぶつかるのを防止する。   Then, following the movement of the handle 41, the body of the user M swings so as to draw a figure 8, and the muscles around the knee of the user M in order to support such swinging of the body. Can be twisted horizontally (turning horizontally), which can relax the muscles around the knee. The elastic bodies 6 a and 6 b prevent the swinging user M's abdomen from directly hitting the handle 41.

また、ハンドル41を旋回させることによってハンドル41には遠心力が働き、この遠心力に抗してハンドル操作(パドリング動作)を行うので、膝の旋回運動に必要な膝回りの筋力を鍛えることができ、膝の旋回運動を改善することができる。更に、ハンドル41には重り7を装着可能であるから、重り7を調節することにより膝への負荷を調節でき、使用者Mの体力に合ったトレーニングが可能になる。また、重り7をハンドル41に装着しても、これにより大きくなるのは遠心力のみであり、重り7の重力方向の負荷は支柱3により支えられ膝にはかからないので、膝に無理な負担はかからない。   Further, a centrifugal force acts on the handle 41 by turning the handle 41, and a handle operation (paddling operation) is performed against this centrifugal force, so that the muscle strength around the knee necessary for the knee turning motion can be trained. And can improve the knee turning motion. Furthermore, since the weight 7 can be attached to the handle 41, the load on the knee can be adjusted by adjusting the weight 7, and training suitable for the physical strength of the user M becomes possible. Even when the weight 7 is attached to the handle 41, only the centrifugal force is increased by this, and the load in the gravity direction of the weight 7 is supported by the support column 3 and does not apply to the knee. It does not take.

上述したように、本実施形態のトレーニングマシン1を用いることにより、膝まわりの筋肉をほぐすことができ、また膝の曲げ伸ばしに必要な旋回運動を改善できる。そして膝の旋回運動が改善されることで、歩行時等における膝への負担が減り、衝撃に対する膝関節の痛みが軽減され、階段の昇降動作も楽になる。更に、パドリング動作によるハンドル1の特殊な軌道動作により、バランス感覚の改善も期待でき、転倒やふらつきを防止できる。   As described above, by using the training machine 1 of the present embodiment, the muscles around the knee can be loosened, and the turning motion necessary for bending and stretching the knee can be improved. By improving the knee turning motion, the burden on the knee during walking or the like is reduced, the pain of the knee joint with respect to the impact is reduced, and the elevating operation of the stairs is facilitated. Furthermore, the special orbital motion of the handle 1 by paddling motion can also be expected to improve the sense of balance and prevent falls and wobbling.

なお、足幅を広くして同様の動作を行うと、股関節まわりの筋肉に対して上述したのと同様の効果を得ることができる。   If the same operation is performed with the foot width widened, the same effect as described above can be obtained for the muscles around the hip joint.

以上、本発明の実施形態に係るトレーニングマシンについて添付の図面を参照して説明したが、本発明はかかる実施形態に限定されず、本発明の範囲を逸脱することなく種々の変形、修正が可能である。   As described above, the training machine according to the embodiment of the present invention has been described with reference to the accompanying drawings, but the present invention is not limited to the embodiment, and various modifications and corrections can be made without departing from the scope of the present invention. It is.

例えば、上記実施形態においては、第1回転軸R1と第2回転軸R2とハンドル41の中心線C1とを1点(点P)で交わるようにしたが、これらが1点で交わらなくても上述したのと同様のパドリング動作は可能である。   For example, in the above embodiment, the first rotation axis R1, the second rotation axis R2, and the center line C1 of the handle 41 intersect at one point (point P), but these may not intersect at one point. A paddling operation similar to that described above is possible.
