For example, Patent Document 1 discloses a training device that allows both arms to be exercised.
　特許文献１に記載のトレーニング器具によると、筋肉の硬化を伴うことなく、筋肉痛、疲労等の身体へ与える負担が少なく、また、柔軟で弾力性の富んだ肩部、腕部、背部などの筋肉等を得ることができる。 According to the training device described in Patent Document 1, there is no hardening of muscles, there is less burden on the body such as muscle pain and fatigue, and the training device is flexible and has a lot of elasticity in the shoulders, arms, back, etc. You can gain muscle etc.
　特許文献１のトレーニング器具は、トレーニング器具側のウェイト（錘）から延びるワイヤーとユーザが握る握持部との間に、昇降揺動部材と称される回動軸と歯車等を備える負荷伝達機構部を設けている。単にウェイトとユーザが握る握持部とをワイヤーによって直に接続する構成のトレーニング器具と比較して、特許文献１のトレーニング器具は昇降揺動部材（負荷伝達機構部）が設けられていることにより、ユーザが鍛えようとする腕のひねり動作により生じる負荷を加えることができる。そのため、単調方向の筋肉の鍛錬に留まらず、負荷が伴うひねり動作により腕の骨の周りの筋肉をより多く動かすこととなり、柔軟性及び弾力性を備えた筋力の習得が可能となる。 The training device of Patent Document 1 has a load transmission mechanism that includes a rotating shaft called an elevating swinging member, gears, etc. between a wire extending from a weight on the training device side and a grip part held by a user. We have established a department. Compared to training equipment that simply connects the weight and the grip part that the user grasps directly using a wire, the training equipment of Patent Document 1 is equipped with an elevating and swinging member (load transmission mechanism part). , it is possible to apply the load caused by the arm twisting motion that the user is trying to exercise. Therefore, rather than training the muscles in a monotonous direction, the muscles around the arm bones are moved more by twisting motions that involve a load, and it becomes possible to acquire muscle strength with flexibility and elasticity.

With reference to FIGS. 1 to 5 and FIG. 34, the configuration and operation of the training device load transmission mechanism section 1A of the first embodiment will be described. The training device load transmission mechanism section 1A includes an outer casing 2 and an inner casing 3. The inner casing 3 is housed in the outer casing 2 and reciprocates inside the outer casing 2 in one direction. A slide rail (not shown) is interposed between the outer casing 2 and the inner casing 3 to reduce the sliding friction that occurs between the outer casing 2 and the inner casing 3. Slide rails include roller types and bearing types.
＜第１実施形態のトレーニング器具用負荷伝達機構部１Ａの構成についての説明＞
　内側筐体３は主動軸部４と中間軸部５とクランク軸部６とを備え、外側筐体２は摺動軸部１３を備える。主動軸部４と摺動軸部１３の間の各軸部を介して主動軸部４と摺動軸部１３の相互に動力が伝達可能である。 <Description of the configuration of the training device load transmission mechanism section 1A of the first embodiment>
The inner casing 3 includes a main drive shaft 4 , an intermediate shaft 5 , and a crankshaft 6 , and the outer casing 2 includes a sliding shaft 13 . Power can be transmitted between the main drive shaft part 4 and the sliding shaft part 13 via each shaft part between the main drive shaft part 4 and the sliding shaft part 13 .
　第１実施形態のトレーニング器具用負荷伝達機構部１Ａでは、主動軸部４、中間軸部５、及びクランク軸部６の各軸部は、内側筐体３に回動可能に軸支される。図１から理解されるように、主動軸部４は内側筐体３に取り付けられた主動軸軸受４ａ、４ｂに回動自在に軸支され、中間軸部５は内側筐体３に取り付けられた中間軸軸受５ａ、５ｂに回動自在に軸支される。 In the training device load transmission mechanism section 1A of the first embodiment, each shaft section of the main drive shaft section 4, the intermediate shaft section 5, and the crankshaft section 6 is rotatably supported by the inner housing 3.

　摺動軸部１３は、外側筐体２に設けられた摺動軸受１３ａに軸支されて、図１における上下方向に変位を許容される。また、摺動軸受１３ａは、摺動軸部１３に対して線接触により軸支されてもよい。例えば、摺動軸受１３ａの内周面がすり鉢形状をしており、当該内周面の一部が摺動軸部１３の外周面に線接触することで軸支されてもよい。これによれば、摺動軸部１３は、摺動軸受１３ａとの間の摺動摩擦を低減させることができ、より滑らかな図１における上下方向の変位をすることができる。 The sliding shaft portion 13 is pivotally supported by a sliding bearing 13a provided in the outer housing 2, and is allowed to be displaced in the vertical direction in FIG. Furthermore, the sliding bearing 13a may be supported by line contact with the sliding shaft portion 13. For example, the inner circumferential surface of the sliding bearing 13a may have a mortar shape, and a portion of the inner circumferential surface may be in line contact with the outer circumferential surface of the sliding shaft portion 13 to be pivotally supported. According to this, the sliding shaft portion 13 can reduce sliding friction with the sliding bearing 13a, and can perform smoother vertical displacement in FIG. 1.

A guide column 140 (see FIGS. 6 to 11) is inserted into the connecting tube 8. For the connecting tube portion 8, a member having low sliding resistance, such as fluororesin, is used, for example. As a result, the training device load transmission mechanism section 1A can be smoothly moved up and down and rotated in the first training device 100.

The first joint piece 12a and the second joint piece 12c are connected by a first universal joint 12b, which is a universal joint 40. The second joint piece 12c and the third joint piece 12e are connected by a second universal joint 12d, which is a universal joint 40.
The universal joint 40 can freely change the angle at which the two rotating shafts join to transmit the rotational motion of one rotating shaft to the other rotating shaft at an angle. The universal joint 40 may be any of various types of universal joints or a rod member called a connecting rod 41 (see FIG. 30). A connecting rod 41 is used in the universal joint 40 (first universal joint 12b and second universal joint 12d) shown in FIG. The connecting rod 41 includes two through holes (a first through hole 41a and a second through hole 41b) that are orthogonal to each other.

Examples of the universal joint include a top-shaped universal joint and a constant velocity universal joint.
The connecting joint part 12 includes three connecting pieces 30, a first joint piece 12a, a second joint piece 12c, and a third joint piece 12e, and a universal joint 40 (first joint piece) connecting these adjacent connecting pieces 30. It is composed of a universal joint 12b and a second universal joint 12d). Although the connecting joint portion 12 is configured to include three connecting pieces 30, the present invention is not limited to this, and may include four or more connecting pieces 30. The connecting joint 12 includes at least two universal joints 40 . For example, a connecting joint 12 that includes four connecting pieces 30 includes two or three universal joints 40 . The first joint piece 12a is rotatably attached with a pin 12f so as to straddle the side surface of the crankshaft portion 6. The pin 12f is orthogonal to the rotation axis of the crankshaft portion 6, and serves as the rotation axis of the first joint piece 12a.

It can be bent at a predetermined angle in two orthogonal directions using the universal joint 12b as a base point.
　第２自在継手１２ｄは、第２関節片１２ｃと第３関節片１２ｅとを直角に交差する２本の回転軸を用いて接続し、第２関節片１２ｃと第３関節片１２ｅとは第２自在継手１２ｄを基点にして直交する２方向に所定角度折れ曲がることができる。 The second universal joint 12d connects the second joint piece 12c and the third joint piece 12e using two rotating shafts that intersect at right angles. It can be bent at a predetermined angle in two orthogonal directions using the universal joint 12d as a base point.
　第１関節片１２ａはその一端においてクランク軸部６の軸方向に直交する第４中心軸１２ｋ（ピン１２ｆ）を有する回動が許容されてクランク軸部６に接続されるので、第１関節片１２ａはクランク軸部６の軸方向に沿うように回動する。また、第１関節片１２ａはその他端において第１自在継手１２ｂを介して第２関節片１２ｃに接続されるので、第１関節片１２ａは第２関節片１２ｃに対して直交する２方向に屈曲することができる。 The first joint piece 12a has a fourth central axis 12k (pin 12f) perpendicular to the axial direction of the crankshaft part 6 at one end thereof, and is allowed to rotate and is connected to the crankshaft part 6. 12a rotates along the axial direction of the crankshaft portion 6. Moreover, since the first joint piece 12a is connected to the second joint piece 12c via the first universal joint 12b at the other end, the first joint piece 12a can be bent in two directions perpendicular to the second joint piece 12c. can do.

The piece 12c can be bent in two directions perpendicular to the third joint piece 12e.
　第３関節片１２ｅは、第２関節片１２ｃと接続している端部とは反対側の端部において、摺動軸部１３の第１端部１３ｂに接続される。 The third joint piece 12e is connected to the first end 13b of the sliding shaft portion 13 at the end opposite to the end connected to the second joint piece 12c.
　主動軸部４は、下端部にユーザが握持する握持部１１が接続される。握持部１１は、ユーザが力を入力する入力部である。そして、ユーザの手、腕の動きは握持部１１を介して主動軸部４に伝わり主動軸部４自体も回動及び水平移動をする。後出の第１トレーニング器具１００から理解されるように、主動軸部４に接続される握持部１１は環状物、特には手の指により握られるため、矩形の環状である。図６ないし１１に示されるように、握持部１１は平面視において矩形（四角形）状であり、切れ目無くつながった環を形成している。 A grip portion 11 that is gripped by a user is connected to the lower end of the main drive shaft portion 4 . The grip section 11 is an input section through which the user inputs force. The movements of the user's hands and arms are transmitted to the main drive shaft section 4 through the grip section 11, and the main drive shaft section 4 itself rotates and moves horizontally. As will be understood from the first training device 100 described later, the gripping portion 11 connected to the main drive shaft portion 4 is held by an annular object, particularly the fingers of a hand, and therefore has a rectangular annular shape. As shown in FIGS. 6 to 11, the grip portion 11 has a rectangular (square) shape in plan view, and forms a continuous ring.
　中間軸部５は主動軸部４の回動と連動して回動する。そして、主動軸部４と中間軸部５との間に懸架され主動軸部４と中間軸部５の互いの回動を伝達する第１回動伝達部１Ｋが備えられる。主動軸部４の回動は、第１回動伝達部１Ｋによって、中間軸部５に伝えられる。また、摺動軸部１３に作用する外力に起因する中間軸部５の回動しようとする力は、第１回動伝達部１Ｋによって、主動軸部４に伝達される。主動軸部４と中間軸部５は互いに平行となる配置である。 The intermediate shaft portion 5 rotates in conjunction with the rotation of the main drive shaft portion 4. A first rotation transmission section 1K is provided which is suspended between the main drive shaft section 4 and the intermediate shaft section 5 and transmits mutual rotation of the main drive shaft section 4 and the intermediate shaft section 5. The rotation of the main drive shaft portion 4 is transmitted to the intermediate shaft portion 5 by the first rotation transmission portion 1K. Further, a force that causes the intermediate shaft portion 5 to rotate due to an external force acting on the sliding shaft portion 13 is transmitted to the main drive shaft portion 4 by the first rotation transmission portion 1K. The driving shaft portion 4 and the intermediate shaft portion 5 are arranged parallel to each other.
　主動軸部４と中間軸部５とは、内側筐体３に回動自在に軸支されており、主動軸部４と中間軸部５とは内側筐体３により連結固定され、内側筐体３によって主動軸部４と中間軸部５との互いの水平移動が伝達される。 The main drive shaft part 4 and the intermediate shaft part 5 are rotatably supported by the inner case 3, and the main drive shaft part 4 and the intermediate shaft part 5 are connected and fixed by the inner case 3. 3 transmits the horizontal movement of the main drive shaft section 4 and the intermediate shaft section 5 to each other.
　トレーニング器具用負荷伝達機構部１Ａでは、第１回動伝達部１Ｋは伝達チェーン１０を備える（図１ないし５中、太い破線で示される。）。伝達チェーン１０は、例としてローラーチェーン、リーフチェーンなどが挙げられる。第１回動伝達部１Ｋの伝達チェーン１０の懸架と噛み合わせのため、主動軸部４に主動軸スプロケット４Ｃと中間軸部５に中間軸スプロケット５Ｃが備えられる。第１回動伝達部１Ｋは、伝達チェーン１０を採用する代わりにベルトとプーリーの組み合わせ（図示せず）としてもよい。ベルトの例として、Ｖベルト、平ベルト、歯付きベルトなどが挙げられる。 In the training equipment load transmission mechanism section 1A, the first rotation transmission section 1K includes a transmission chain 10 (indicated by thick broken lines in FIGS. 1 to 5). Examples of the transmission chain 10 include a roller chain and a leaf chain. In order to suspend and engage the transmission chain 10 of the first rotation transmission section 1K, the main drive shaft section 4 is provided with a main drive shaft sprocket 4C, and the intermediate shaft section 5 is provided with an intermediate shaft sprocket 5C. The first rotation transmission section 1K may be a combination of a belt and a pulley (not shown) instead of employing the transmission chain 10. Examples of belts include V-belts, flat belts, toothed belts, and the like.
　図１に示すように、中間軸部５とクランク軸部６とは直交する関係にあり、中間軸部５とクランク軸部６との間には、第２回動伝達部１Ｍが備えられる。第２回動伝達部１Ｍは、中間軸部５とクランク軸部６との互いの回動を伝達する。第２回動伝達部１Ｍは、直角に交差する２軸間で回転を伝達する役割を担う。ここで２軸間とは、中間軸部５とクランク軸部６との間のことである。 As shown in FIG. 1, the intermediate shaft portion 5 and the crankshaft portion 6 are in a perpendicular relationship, and a second rotation transmission portion 1M is provided between the intermediate shaft portion 5 and the crankshaft portion 6. The second rotation transmission section 1M transmits mutual rotation between the intermediate shaft section 5 and the crankshaft section 6. The second rotation transmission section 1M plays a role of transmitting rotation between two axes that intersect at right angles. Here, the term "between two shafts" refers to the space between the intermediate shaft section 5 and the crankshaft section 6.
　第１実施形態において、第２回動伝達部１Ｍは、中間軸部５に備えられる中間軸部傘歯車５ｄと、クランク軸部６に備えられ中間軸部傘歯車５ｄと歯合するクランク軸傘歯車６ｃを備える。中間軸部５の回動動作はクランク軸部６に直角に連動する。なお、中間軸部５とクランク軸部６とを直交して接続する第２回動伝達部１Ｍの機構として、例えば、クラウンギヤと平歯車、ウォームとウォームホイールの組み合わせ等の機構が挙げられる。 In the first embodiment, the second rotation transmission section 1M includes an intermediate shaft bevel gear 5d provided on the intermediate shaft section 5, and a crankshaft bevel gear provided on the crankshaft section 6 that meshes with the intermediate shaft bevel gear 5d. A gear 6c is provided. The rotational movement of the intermediate shaft portion 5 is interlocked with the crankshaft portion 6 at right angles. Note that the mechanism of the second rotation transmission section 1M that orthogonally connects the intermediate shaft section 5 and the crankshaft section 6 includes, for example, a mechanism such as a combination of a crown gear and a spur gear, a worm and a worm wheel, and the like.
　摺動軸部１３は外側筐体２において中間軸部５と平行となる位置に配置される。クランク軸部６の回動及び軸方向への水平移動は連結関節部１２を介して紙面上では上下動の動作に変換され、摺動軸部１３に伝達される。摺動軸部１３は、第１トレーニング器具１００（図６ないし１１参照）の負荷の大きさを調整自在な負荷付与部１３０に連結される。 The sliding shaft portion 13 is arranged in the outer housing 2 at a position parallel to the intermediate shaft portion 5. Rotation and horizontal movement in the axial direction of the crankshaft portion 6 are converted into vertical movement on the paper via the connecting joint portion 12 and transmitted to the sliding shaft portion 13 . The sliding shaft portion 13 is connected to a load applying portion 130 that can adjust the magnitude of the load on the first training device 100 (see FIGS. 6 to 11).
　クランク軸部６の回動及び軸方向の水平移動に伴って連結関節部１２が動かされ、連結関節部１２を介して摺動軸部１３に上下動の動作が生じる。つまり、主動軸部４の軸回転及びクランク軸部６の軸方向への水平移動により摺動軸部１３が上下動し、摺動軸部１３に連結された第１トレーニング器具１００（図６ないし１１参照）の負荷付与部１３０（ウェイト１３１）が上下動する。なお、トレーニング器具用負荷伝達機構部１Ａにおいて、第１回動伝達部１Ｋは主動軸部４に設けられた主動軸スプロケット４ｃと、中間軸スプロケット５ｃと、主動軸スプロケット４ｃと中間軸スプロケット５ｃの間に懸架された伝達チェーン１０とを備える。第２回動伝達部１Ｍは、中間軸部５に設けられた中間軸部傘歯車５ｄと、同中間軸部傘歯車５ｄと歯合するクランク軸傘歯車６ｃとを備える。第１回動伝達部１Ｋ及び第２回動伝達部１Ｍにより、主動軸部４の回転がクランク軸部６に伝達される。主動軸部４とクランク軸部６とは内側筐体３において軸支されていることから、主動軸部４のクランク軸部６の軸方向への水平移動は内側筐体３を介してクランク軸部６に伝達される。 As the crankshaft portion 6 rotates and moves horizontally in the axial direction, the connecting joint portion 12 is moved, and a vertical motion is generated in the sliding shaft portion 13 via the connecting joint portion 12. In other words, the sliding shaft 13 moves up and down due to the axial rotation of the main drive shaft 4 and the horizontal movement in the axial direction of the crankshaft 6, and the first training device 100 (see FIGS. 6 and 6) connected to the sliding shaft 13 moves up and down. 11) moves up and down. In addition, in the load transmission mechanism section 1A for training equipment, the first rotation transmission section 1K includes a main drive shaft sprocket 4c provided on the main drive shaft section 4, an intermediate shaft sprocket 5c, and a main drive shaft sprocket 4c and an intermediate shaft sprocket 5c. and a transmission chain 10 suspended between them. The second rotation transmission portion 1M includes an intermediate shaft bevel gear 5d provided on the intermediate shaft portion 5, and a crankshaft bevel gear 6c meshing with the intermediate shaft bevel gear 5d. The rotation of the main drive shaft section 4 is transmitted to the crankshaft section 6 by the first rotation transmission section 1K and the second rotation transmission section 1M. Since the main drive shaft section 4 and the crankshaft section 6 are pivotally supported in the inner case 3, the horizontal movement of the crankshaft section 6 of the main drive shaft section 4 in the axial direction is caused by moving the crankshaft section 6 through the inner case 3. 6.
　トレーニング器具用負荷伝達機構部１Ａにおいて、連結関節部１２により、クランク軸部６の回動及び軸方向の水平移動により摺動軸部１３が進退動する。こうして、主動軸部４（握持部１１）は負荷付与部１３０（ともに図６ないし１１参照）の負荷に比例する力によって付勢される。そして、ユーザが入力部である握持部１１を主動軸部４に対して回転付勢力に抗して軸回転させることにより、摺動軸部１３は外側筐体２の内部に引き込まれ、摺動軸部１３に連結された負荷付与部１３０は引張される（引き上げられる）。さらに、ユーザが握持部１１を主動軸部４に対して付勢力に抗ってクランク軸部６の軸方向に水平移動させることにより、摺動軸部１３は外側筐体２の内部に引き込まれ、摺動軸部１３に連結された負荷付与部１３０は引張される（引き上げられる）。 In the training device load transmission mechanism section 1A, the sliding shaft section 13 moves forward and backward by the rotation of the crankshaft section 6 and the horizontal movement in the axial direction by the connecting joint section 12. In this way, the main driving shaft section 4 (grip section 11) is biased by a force proportional to the load of the load applying section 130 (see FIGS. 6 to 11). Then, when the user rotates the grip part 11, which is an input part, against the rotational biasing force with respect to the main drive shaft part 4, the sliding shaft part 13 is drawn into the outer casing 2, and the sliding shaft part 13 is pulled into the outer housing 2. The load application section 130 connected to the dynamic shaft section 13 is tensed (pulled up). Furthermore, when the user horizontally moves the grip part 11 against the main drive shaft part 4 in the axial direction of the crankshaft part 6 against the biasing force, the sliding shaft part 13 is pulled into the inside of the outer housing 2. As a result, the load application section 130 connected to the sliding shaft section 13 is pulled (pulled up).
＜トレーニング器具用負荷伝達機構部１Ａの動作についての説明＞
　図２から図５を参照して、トレーニング器具用負荷伝達機構部１Ａの動作について説明する。図２はトレーニング器具用負荷伝達機構部１Ａ（以下、負荷伝達機構部１Ａとする）の動作における初期姿勢を示す図であり、図３は負荷伝達機構部１Ａの主動軸部４の回動に伴う動作を説明するための図であり、図４は負荷伝達機構部１Ａの主動軸部４の水平移動に伴う動作を説明するための図であり、図５は負荷伝達機構部１Ａの主動軸部４の回動及び水平移動に伴う動作を説明するための図である。 <Description of the operation of the training equipment load transmission mechanism section 1A>
The operation of the training device load transmission mechanism section 1A will be described with reference to FIGS. 2 to 5. FIG. 2 is a diagram showing the initial posture during operation of the load transmission mechanism section 1A for training equipment (hereinafter referred to as load transmission mechanism section 1A), and FIG. 3 shows the rotation of the main drive shaft section 4 of the load transmission mechanism section 1A. FIG. 4 is a diagram for explaining the operation accompanying the horizontal movement of the main drive shaft section 4 of the load transmission mechanism section 1A, and FIG. FIG. 4 is a diagram for explaining operations accompanying rotation and horizontal movement of the portion 4. FIG.
　図２に示す負荷伝達機構部１Ａの動作における初期姿勢は、主動軸部４が図２中の一番右に位置し、連結関節部１２が上向きに一番伸張している状態である。すなわち、負荷伝達機構部１Ａの動作における初期姿勢では、摺動軸部１３の第２端部１３ｃが最も高い位置にある。 The initial position in the operation of the load transmission mechanism section 1A shown in FIG. 2 is a state in which the main drive shaft section 4 is located at the far right in FIG. 2 and the connecting joint section 12 is extended upward the most. That is, in the initial posture of the operation of the load transmission mechanism section 1A, the second end 13c of the sliding shaft section 13 is at the highest position.
　図３に示す負荷伝達機構部１Ａは、図２に示す初期姿勢における主動軸部４の位置に留まり回動のみ行われた状態を示す。ユーザにより握持部１１が回動され、握持部１１の回動が主動軸部４の回動となり、当該回動が第１回動伝達部１Ｋを介して中間軸部５に伝達され、さらに第２回動伝達部１Ｍを介してクランク軸部６に伝達される。クランク軸部６の回動に伴い、連結関節部１２の第１自在継手１２ｂ及び第２自在継手１２ｄがクランク軸の周方向に屈曲する。当該屈曲により負荷伝達機構部１Ａの内部で連結関節部１２が湾曲して摺動軸部１３を負荷伝達機構部１Ａの内部に引き込み、摺動軸部１３に連結された第１トレーニング器具１００（図６ないし１１参照）の負荷付与部１３０（ウェイト１３１）を持ち上げる。従って、ユーザによる握持部１１の回動に対して、負荷付与部１３０（ウェイト１３１）の負荷が作用することとなる。 The load transmission mechanism section 1A shown in FIG. 3 shows a state where the main drive shaft section 4 remains in the initial position shown in FIG. 2 and only rotates. The grip part 11 is rotated by the user, the rotation of the grip part 11 becomes the rotation of the main drive shaft part 4, and the rotation is transmitted to the intermediate shaft part 5 via the first rotation transmission part 1K, Further, the rotational motion is transmitted to the crankshaft section 6 via the second rotation transmission section 1M. As the crankshaft portion 6 rotates, the first universal joint 12b and the second universal joint 12d of the connecting joint portion 12 bend in the circumferential direction of the crankshaft. Due to the bending, the connecting joint part 12 is curved inside the load transmission mechanism part 1A, and the sliding shaft part 13 is drawn into the inside of the load transmission mechanism part 1A, and the first training device 100 ( Lift up the load applying section 130 (weight 131) (see FIGS. 6 to 11). Therefore, the load of the load applying section 130 (weight 131) acts on the rotation of the grip section 11 by the user.
　図４に示す負荷伝達機構部１Ａは、図２に示す初期姿勢における主動軸部４の位置から主動軸部４を回動することなく図中左側に水平移動させた状態を示す。ユーザにより握持部１１が図中左側に水平移動され、握持部１１の水平移動が主動軸部４の水平移動となり、当該水平移動が内側筐体３を介して中間軸部５及びクランク軸部６に伝達される。クランク軸部６の当該水平移動に伴い、連結関節部１２の第１自在継手１２ｂ及び第２自在継手１２ｄがクランク軸部６の軸方向に屈曲する。当該屈曲により負荷伝達機構部１Ａの内部で連結関節部１２が湾曲して摺動軸部１３を負荷伝達機構部１Ａの内部に引き込み、摺動軸部１３に連結された第１トレーニング器具１００（図６ないし１１参照）の負荷付与部１３０（ウェイト１３１）を持ち上げる。従って、ユーザによる握持部１１の水平移動に対して、負荷付与部１３０（ウェイト１３１）の負荷が作用することとなる。 The load transmission mechanism section 1A shown in FIG. 4 is shown in a state in which the main drive shaft section 4 is horizontally moved to the left in the figure without rotation from the position of the main drive shaft section 4 in the initial posture shown in FIG. The grip part 11 is horizontally moved to the left side in the figure by the user, and the horizontal movement of the grip part 11 becomes the horizontal movement of the main drive shaft part 4, and the horizontal movement moves the intermediate shaft part 5 and the crankshaft via the inner housing 3. 6. As the crankshaft 6 moves horizontally, the first universal joint 12b and the second universal joint 12d of the connecting joint 12 bend in the axial direction of the crankshaft 6. Due to the bending, the connecting joint part 12 is curved inside the load transmission mechanism part 1A, and the sliding shaft part 13 is drawn into the inside of the load transmission mechanism part 1A, and the first training device 100 ( Lift up the load applying section 130 (weight 131) (see FIGS. 6 to 11). Therefore, the load of the load applying section 130 (weight 131) acts on the horizontal movement of the grip section 11 by the user.
　図５に示す負荷伝達機構部１Ａは、図２に示す初期姿勢における主動軸部４の位置から主動軸部４を回動すると供に図中左側に水平移動させた状態を示す。ユーザにより握持部１１が回動されると供に図中左側に水平移動され、握持部１１の回動及び水平移動が主動軸部４の回動及び水平移動となる。握持部１１の回動は第１回動伝達部１Ｋを介して中間軸部５に伝達され、さらに第２回動伝達部１Ｍを介してクランク軸部６に伝達される。握持部１１の水平移動は内側筐体３を介して中間軸部５及びクランク軸部６に伝達される。クランク軸部６の当該回動及び当該水平移動に伴い、連結関節部１２の第１自在継手１２ｂ及び第２自在継手１２ｄがクランク軸の周方向及び軸方向に屈曲する。当該屈曲により負荷伝達機構部１Ａの内部で連結関節部１２が湾曲して摺動軸部１３を負荷伝達機構部１Ａの内部に引き込み、摺動軸部１３に連結された第１トレーニング器具１００（図６ないし１１参照）の負荷付与部１３０（ウェイト１３１）を持ち上げる。従って、ユーザによる握持部１１の回動及び水平移動に対して、負荷付与部１３０（ウェイト１３１）の負荷が作用することとなる。 The load transmission mechanism section 1A shown in FIG. 5 is shown in a state in which the main drive shaft 4 is rotated and horizontally moved to the left in the figure from the position of the main drive shaft 4 in the initial posture shown in FIG. When the grip part 11 is rotated by the user, it is horizontally moved to the left in the figure, and the rotation and horizontal movement of the grip part 11 become the rotation and horizontal movement of the main drive shaft part 4. The rotation of the grip portion 11 is transmitted to the intermediate shaft portion 5 via the first rotation transmission portion 1K, and further transmitted to the crankshaft portion 6 via the second rotation transmission portion 1M. Horizontal movement of the grip portion 11 is transmitted to the intermediate shaft portion 5 and the crankshaft portion 6 via the inner housing 3. With the rotation and horizontal movement of the crankshaft section 6, the first universal joint 12b and the second universal joint 12d of the connecting joint section 12 are bent in the circumferential direction and the axial direction of the crankshaft. Due to the bending, the connecting joint part 12 is curved inside the load transmission mechanism part 1A, and the sliding shaft part 13 is drawn into the inside of the load transmission mechanism part 1A, and the first training device 100 ( Lift up the load applying section 130 (weight 131) (see FIGS. 6 to 11). Therefore, the load of the load applying section 130 (weight 131) acts on the rotation and horizontal movement of the grip section 11 by the user.
　握持部１１を回動すると共に水平移動する動作は、握持部１１を回動のみ又は水平移動のみする場合に比べて、連結関節部１２の湾曲の程度が大きくなり摺動軸部１３を負荷伝達機構部１Ａの内部により多く引き込みより多くのエネルギーを消費することとなる。 When the gripping part 11 is rotated and horizontally moved, the degree of curvature of the connecting joint part 12 becomes larger than when the gripping part 11 is only rotated or only horizontally moved. This results in more energy being consumed inside the load transmission mechanism section 1A than when it is being pulled in.
　なお、図３、４、５に示す負荷伝達機構部１Ａの状態では、負荷付与部１３０（ウェイト１３１）の負荷の作用により図２に示す初期状態に戻ろうとする力（復元力）が握持部１１に作用する。ユーザはこの復元力に抗いながら図３、４、５の状態を維持するか、握持部１１をさらに回動若しくは水平移動させるか、又は初期姿勢の状態に戻すこととなる。 In addition, in the state of the load transmission mechanism section 1A shown in FIGS. 3, 4, and 5, the force (restoring force) to return to the initial state shown in FIG. 2 due to the action of the load on the load applying section 130 (weight 131) is 11. The user either maintains the states shown in FIGS. 3, 4, and 5 while resisting this restoring force, further rotates or horizontally moves the grip portion 11, or returns it to the initial posture.

　第１トレーニング器具１００の構成は図６ないし図７にて示される。第１トレーニング器具１００は、負荷伝達機構部１Ａを装着した器具である。 <First training equipment 100>

The seat support 112 is inserted into a hole vertically extending in front of the center of the lower surface of the framework 120, and the seating portion 110 is supported by the framework 120. The framework 120 includes a thigh presser 121 that prevents the thighs of a user seated on the seat 111 from lifting up. Preferably, the thigh presser part 121 is provided to allow the user to create an appropriate arch in the back during training.
　負荷付与部１３０は、枠組１２０に設けられた負荷の大きさを調整自在とし、金属製の重量部材である複数枚の板状プレートからなるウェイト１３１と、同ウェイト１３１を枠組１２０に上下動自在に支持するウェイト案内支柱１３２と、ウェイト１３１を相互に連結離別自在とすることが可能なクランプ（図示せず）を具備する。ウェイト１３１の枚数が加減されて負荷付与部１３０の荷重（負荷）は調整される。一対の円柱状のウェイト案内支柱１３２は、着座部１１０の後方にて枠組１２０に上下端が所定の左右の間隔を隔ててそれぞれ鉛直方向に固定され、ウェイト１３１の各板状プレートがその貫通孔を挿通され積層し、枠組１２０に上下動自在に支持されている。 The load applying unit 130 can freely adjust the magnitude of the load provided to the framework 120, and includes a weight 131 made of a plurality of plate-shaped plates, which are heavy metal members, and the weight 131 can be freely moved up and down on the framework 120.

By increasing or decreasing the number of weights 131, the load on the load applying section 130 is adjusted. A pair of cylindrical weight guide columns 132 are vertically fixed to the framework 120 at the rear of the seating section 110 with their upper and lower ends spaced apart from each other by a predetermined lateral interval, and each plate-shaped plate of the weight 131 has its through hole. are inserted and stacked, and supported by the framework 120 so as to be vertically movable.
　２個の負荷伝達機構部１Ａは、２本の案内支柱１４０に接続部７により上下動自在、かつ水平方向に回動自在にそれぞれ嵌合されている。負荷伝達機構部１Ａの主動軸部４に接続される握持部１１は、ユーザが手でそれぞれ把持し力を入力する入力部となる環状物のハンドルである。各握持部１１は負荷伝達機構部１Ａに対してそれぞれ水平方向に軸回転できる。また、握持部１１の揺動も可能である。各握持部１１は、初期状態（図６及び図７参照）においては、各握持部１１を把持した使用者の手の甲が第１トレーニング器具１００の外側を向く位置である。各握持部１１は、初期状態においては、座席１１１に着座したユーザが腕を上方に伸ばした手の位置よりさらに上方に位置する。そして、ユーザは握持部１１を通じて負荷伝達機構部１Ａを下降させることが可能である。このとき、ユーザは両腕を正中（体の左右の真ん中のライン）から外側へ胸元にて開くことができる（図８及び図９参照）。 The two load transmission mechanism parts 1A are respectively fitted to the two guide columns 140 via the connection parts 7 so as to be vertically movable and horizontally rotatable.

The tension members 180 of the first training device 100 shown in FIGS. 6, 7, 8, and 9 are two ropes or wires of the same length, and one end of each of the two tension members 180 is attached to a weight. 131, and the other end of each is connected to the load transmission mechanism section 1A. Two tension members 180, one end of which is fixed to the weight 131, are each wound around the direction change guide wheel 170. The direction change guide wheel 170 converts the downward load applied to the tension member 80 by the weight 131 into an upward load.
On the other hand, the tension member 180 of the first training device 100 shown in FIGS. 10 and 11 uses one rope or wire. Both ends of this one tension member 180 are respectively connected to two load transmission mechanism parts 1A. A movable pulley is provided in a box portion 133 provided at the upper end of the weight 131, and the tension member 180 is wound around this movable pulley. When one of the two load transmission mechanisms 1A is pulled down, the tension member 180 lifts the weight 131 upward together with the moving pulley using the other load transmission mechanism 1A as a fulcrum.
　図６及び図７に示す初期状態の場合、負荷伝達機構部１Ａの回転は規制される。これに対し、図８及び図９の状態では、負荷伝達機構部１Ａが正面方向を向くように回転付勢させる力に抗して、ユーザが負荷伝達機構部１Ａを所定角度まで回転させることが可能となる。負荷伝達機構部１Ａが正面方向を向くように回転付勢する力は、負荷付与部１３０の負荷に比例するとともに、負荷伝達機構部１Ａの上下位置におおよそ逆比例している。 In the initial state shown in FIGS. 6 and 7, rotation of the load transmission mechanism section 1A is restricted. On the other hand, in the states shown in FIGS. 8 and 9, the user cannot rotate the load transmission mechanism 1A to a predetermined angle against the force that urges the load transmission mechanism 1A to rotate so as to face the front direction. It becomes possible. The force that urges the load transmission mechanism 1A to rotate so as to face in the front direction is proportional to the load on the load applying section 130 and approximately inversely proportional to the vertical position of the load transmission mechanism 1A.
　なお、図１０及び図１１のように、第１トレーニング器具１００では左右の負荷伝達機構部１Ａの昇降動作を異ならせてトレーニングすることも可能である。
　後述する第２実施形態に係るトレーニング器具用負荷伝達機構部１Ｂ（以下、負荷伝達機構部１Ｂという。）、第４実施形態に係るトレーニング器具用負荷伝達機構部１Ｄ（以下、負荷伝達機構部１Ｄという。）、及び第５実施形態に係るトレーニング器具用負荷伝達機構部１Ｅ（負荷伝達機構部１Ｅという。）は、負荷伝達機構部１Ａに代えて、第１トレーニング器具１００に装着して使用することができる。２個の負荷伝達機構部１Ｂ，１Ｄ、１Ｅは、負荷伝達機構部１Ａと同様に、第１トレーニング器具１００の２本の案内支柱１４０に接続部７により上下動自在、かつ水平方向に回動自在にそれぞれ嵌合される。 In addition, as shown in FIGS. 10 and 11, in the first training device 100, it is also possible to perform training by making the lifting and lowering operations of the left and right load transmission mechanism parts 1A different.

The two load transmission mechanism parts 1B, 1D, and 1E, like the load transmission mechanism part 1A, are connected to the two guide columns 140 of the first training device 100 by connection parts 7 so as to be vertically movable and horizontally rotatable. They are fitted together freely.
　＜第１トレーニング器具１００の使用方法についての説明＞
　第１トレーニング器具１００について、代表的な使用方法を順に説明する。始めにユーザの筋力、目的等を考慮した負荷に合わせて重量のウェイト１３１が配置される。ユーザは正面を向いて座席１１１に着座し、足裏が床面に接地するように座席１１１を適切な高さに調整して固定する。さらに、座席１１１に着座したユーザの大腿部の上面と接する程度に大腿部押え部１２１を適切な高さに調整して固定する。 <Explanation on how to use the first training device 100>
Typical usage methods for the first training device 100 will be explained in order. First, weights 131 are placed according to the load taking into account the user's muscle strength, purpose, and the like. The user sits on the seat 111 facing forward, and adjusts and fixes the seat 111 to an appropriate height so that the soles of the user's feet are in contact with the floor. Furthermore, the thigh presser 121 is adjusted to an appropriate height and fixed to such an extent that it contacts the upper surface of the thigh of the user seated on the seat 111.
　次に、使用者は立ち上がり、正面方向を向いた負荷伝達機構部１Ａの初期状態（図６及び図７参照）に合わせ、手の甲を第１トレーニング器具１００の左右に向けて、握持部１１をそれぞれ把持する。そして、握持部１１を上方に伸ばした手で把持しながら、また握持部１１を下方に引っ張りながら座席１１１に正面方向を向いて着座する。 Next, the user stands up, adjusts the initial state of the load transmission mechanism section 1A facing the front direction (see FIGS. 6 and 7), turns the back of the hand to the left and right sides of the first training device 100, and holds the grip section 11. Grasp each. Then, the user sits on the seat 111 facing forward while grasping the gripping part 11 with the hand extended upward and pulling the gripping part 11 downward.
　次に、ユーザは負荷付与部１３０の負荷に比例した力によって握持部１１に作用する回転付勢力に抗して、両上腕を外側に捻り、各握持部１１を負荷伝達機構部１Ａに対して水平方向に軸回転させて、各握持部１１を把持した手の甲をそれぞれ第１トレーニング器具１００の正面方向に向ける。この「かわし動作」のポジションをとることにより、屈筋と伸筋とが共に「弛緩」して肩や腕がリラックスした状態になる。また、負荷付与部１３０の負荷により握持部１１が上方向に付勢されており、肩甲帯付近等の筋肉が適度に「伸張」される。 Next, the user twists both upper arms outward against the rotational urging force acting on the gripping part 11 by a force proportional to the load of the load applying part 130, and twists each gripping part 11 into the load transmission mechanism part 1A. On the other hand, the grips are rotated in the horizontal direction so that the backs of the hands gripping each grip portion 11 face toward the front of the first training device 100. By adopting this "dodging motion" position, both the flexor and extensor muscles "relax" and the shoulders and arms become relaxed. Moreover, the gripping part 11 is urged upward by the load of the load applying part 130, and muscles in the vicinity of the shoulder girdle and the like are appropriately "stretched".
　次に、ユーザは、適度に「伸張」された肩甲帯付近等の筋肉が「反射」を引き起こすように、負荷付与部１３０の負荷に抗して両腕を屈曲し筋肉を「短縮」させて握持部１１を引き下げる。このとき、さらに上腕を外側に捻る「弛緩」と「伸張」の動作を加えながら、両手で握持部１１を引き下げる。この上腕を外側に捻る動作によって各握持部１１を負荷伝達機構部１Ａに対してさらに外側水平方向に軸回転することにより、ウェイト１３１を引き上げることになり、両腕を引き下げる初動作における負荷が減少する。このように、両腕を屈曲して握持部１１を引き下げて筋肉を「短縮」させるとき、さらに上腕を外側に捻ることによって、「弛緩」と「伸張」の動作を加えながら適切な「短縮」のタイミングを出現させることより、各筋肉群が「弛緩－伸張－短縮」のタイミングを得て、連動性よく動作を行うことができる。 Next, the user flexes both arms against the load of the load applying section 130 to "shorten" the muscles so that the appropriately "stretched" muscles near the shoulder girdle cause a "reflex." and pull down the grip part 11. At this time, the grip portion 11 is pulled down with both hands while further adding "relaxation" and "extension" motions of twisting the upper arm outward. This action of twisting the upper arms outward causes each gripping part 11 to further pivot outwardly in the horizontal direction with respect to the load transmission mechanism part 1A, thereby pulling up the weight 131 and reducing the load in the initial movement of pulling both arms down. Decrease. In this way, when bending both arms and pulling down the grip part 11 to "shorten" the muscles, by further twisting the upper arms outward, the appropriate "shortening" is performed while adding "relaxation" and "stretching" motions. By making the timing of "relaxation-stretching-shortening" appear, each muscle group can obtain the timing of "relaxation-stretching-shortening" and perform movements in good coordination.
　さらに、ユーザは、両腕を引き下げて、さらに上腕を外側に捻りながら外側に伸ばすという、下方向、回転方向、及び横方向の３方向のそれぞれに対して負荷付与部１３０によって適切に調節された負荷をかけることができるので、適度に「伸縮」された各筋肉群が「弛緩－伸張－短縮」のタイミングを得て、連動性よく動作を行うことができる。なお、上腕を外側に伸ばす際には、握持部１１（主動軸部４）の水平移動に対して負荷付与部１３０（ウェイト１３１）によって適切に調整された負荷が付勢される。 Furthermore, the user pulls down both arms, and further extends the upper arms outward while twisting them outward, which is appropriately adjusted by the load applying unit 130 in each of the three directions: downward, rotational, and lateral directions. Since the load can be applied, each muscle group that has been appropriately "stretched and contracted" can obtain the timing of "relaxation-stretching-shortening" and perform movements in a well-coordinated manner. Note that when the upper arm is extended outward, a load appropriately adjusted by the load applying section 130 (weight 131) is applied to the horizontal movement of the grip section 11 (main driving shaft section 4).
　ユーザは、両腕を屈曲して握持部１１を引き下げるとき、各負荷伝達機構部１Ａが正面方向を向くように回転付勢される力に抗して、各負荷伝達機構部１Ａがそれぞれ外側を向くように両腕を外側に漸次広げる。負荷伝達機構部１Ａが正面方向を向くように回転付勢される力は負荷伝達機構部１Ａの位置（高さ）に略逆比例するため、両腕を屈曲させて握持部１１を引き下げることに伴い、両腕を外側に広げることに対する抗力が減少する。そのため、両腕を屈曲させて握持部１１を引き下げるとき、使用者は両腕を外側に広げるように略一定の筋力を出力させることにより、握持部１１を引き下げながら、両腕を漸次外側に広げる動作を滑らかに行うことができ、主動筋と拮抗筋の共縮を防ぐことが可能となる。 When the user bends both arms and pulls down the grip part 11, each load transmission mechanism part 1A resists the force that rotates and urges each load transmission mechanism part 1A to face in the front direction. Gradually spread both arms outward so that they are facing. Since the force that rotationally biases the load transmission mechanism section 1A to face the front direction is approximately inversely proportional to the position (height) of the load transmission mechanism section 1A, it is necessary to bend both arms and pull down the grip section 11. As a result, the resistance to spreading the arms outward decreases. Therefore, when the user bends both arms and pulls down the grip 11, the user outputs a substantially constant amount of muscle force so as to spread both arms outward, thereby gradually moving both arms outward while pulling down the grip 11. It is possible to perform the widening movement smoothly, and it is possible to prevent co-contraction of the agonist and antagonist muscles.
　次に、ユーザは、各握持部１１を略肩部の高さまで引き下げた後、負荷付与部１３０の負荷による各付勢力に従いながら、上腕を内側に捻り両腕を内側に閉じながら両腕を伸ばすことにより、手の甲を握持部１１に従って着座した状態にゆっくりと戻す。これにより、トレーニングの１サイクルが終了する。そして、このトレーニングを適切な回数のサイクルだけ繰り返す。 Next, the user lowers each grip part 11 to approximately the height of the shoulder, and then twists the upper arm inward and closes both arms while following each urging force due to the load of the load applying part 130. By stretching, the back of the hand is slowly returned to the seated state according to the grip part 11. This completes one cycle of training. Then repeat this training for the appropriate number of cycles.

　連結関節部１２は、摺動軸部１３の軸方向に対して直交する中心軸１２ｇを有する回動と、中心軸１２ｇに直交する方向への回動とが、複数の連結片部３０の組み合わせにより許容され、摺動軸部１３に複数の連結片部３０の一（３０（１２ｅ））が接続される。 <First modification 1Ba of load transmission mechanism section 1B for training equipment according to second embodiment>
A first modification 1Ba of the load transmission mechanism section 1B will be described with reference to FIG. 31. In FIG. 31, common parts between the first modification 1Ba (see FIG. 31) and the load transfer mechanism section 1B (see FIGS. 12 and 13) are used in the load transfer mechanism section 1B (see FIGS. 12 and 13). The description thereof will be omitted. Hereinafter, only the portions of the first modification 1Ba that are different from the load transmission mechanism section 1B will be described. The difference between the first modification 1Ba and the load transmission mechanism section 1B lies in the configuration of the connecting joint section 12. The connecting joint part 12 of the load transmission mechanism part 1B includes a first joint piece 12a, a second joint piece 12c, and a third joint piece 12e, which are the connecting piece parts 30. On the other hand, the first modification 1Ba includes a ball joint 42 instead of the second joint piece 12c. Therefore, the connecting joint part 12 of the first modification 1Ba includes the first joint piece 12a which is the connecting piece part 30, the ball joint 42, and the third joint piece 12e.
The connecting joint part 12 has a rotation having a central axis 12g perpendicular to the axial direction of the sliding shaft part 13 and a rotation in a direction perpendicular to the central axis 12g, which is a combination of the plurality of connecting pieces 30. Accordingly, one of the plurality of connecting pieces 30 (30 (12e)) is connected to the sliding shaft 13.
　第１関節片１２ａとボールジョイント４２とは、自在継手４０（４１）である第１自在継手１２ｂにより接続される。ボールジョイント４２と第３関節片１２ｅとは、自在継手４０（４１）である第２自在継手１２ｄにより接続される。自在継手４０の第１自在継手１２ｂと第２自在継手１２ｄは、コンロッド４１（図３０参照）が採用される。 The first joint piece 12a and the ball joint 42 are connected by the first universal joint 12b, which is the universal joint 40 (41). The ball joint 42 and the third joint piece 12e are connected by a second universal joint 12d, which is a universal joint 40 (41). The first universal joint 12b and the second universal joint 12d of the universal joint 40 employ a connecting rod 41 (see FIG. 30).
　ボールジョイントとは、金属球に丸棒を付けたボールスタッドとそれに球面接触するソケットから構成され、任意の方向に回転可能で、かつ並進方向には高い剛性をもつジョイントのことである。ボールスタッドの例としては、リンクボール、及びトリボールジョイントなどがある。
　図３１に示す様に、第１関節片１２ａはクランク軸部６に第４中心軸１２ｋを回転中心とする回動可能に接続される。第１自在継手１２ｂは、第１関節片１２ａに第３中心軸１２ｊを回転中心とする回動可能に接続される。第１自在継手１２ｂと第２自在継手１２ｄとは、ボールジョイント４２を介して任意の方向に回転可能に接続される。第２自在継手１２ｄは、第３関節片１２ｅに第１中心軸１２ｇを回転中心とする回動可能に接続される。第３関節片１２ｅは、摺動軸部１３の下端部に摺動軸部１３の中心軸を中心とする回動可能に接続される。これにより、連結関節部１２は、クランク軸部６の軸方向への水平移動、及びクランク軸部６を中心とする回動を摺動軸部１３の鉛直方向の往復移動に滑らかに変換することができる。 A ball joint is a joint that consists of a ball stud, which is a round rod attached to a metal ball, and a socket that makes spherical contact with the ball stud.It is rotatable in any direction and has high rigidity in the translational direction. Examples of ball studs include link balls and tri-ball joints.
As shown in FIG. 31, the first joint piece 12a is rotatably connected to the crankshaft portion 6 about the fourth central axis 12k. The first universal joint 12b is rotatably connected to the first joint piece 12a about the third central axis 12j. The first universal joint 12b and the second universal joint 12d are connected via a ball joint 42 so as to be rotatable in any direction. The second universal joint 12d is rotatably connected to the third joint piece 12e about the first central axis 12g. The third joint piece 12e is connected to the lower end portion of the sliding shaft portion 13 so as to be rotatable about the central axis of the sliding shaft portion 13. Thereby, the connecting joint portion 12 smoothly converts horizontal movement of the crankshaft portion 6 in the axial direction and rotation around the crankshaft portion 6 into reciprocating movement of the sliding shaft portion 13 in the vertical direction. Can be done.
　第１変形例１Ｂａの連結関節部１２は、連結片部３０の１部にボールジョイント４２を用いることで、連結関節部１２の曲がり具合が滑らかになり、主動軸部４の回転及び水平移動をより滑らかに摺動軸部１３に伝えることができる。
　なお、第１変形例１Ｂａの連結関節部１２は、第１実施形態に係る負荷伝達機構部１Ａ、第３実施形態に係る負荷伝達機構部１Ｃ、第４実施形態に係る負荷伝達機構部１Ｄ、及び第５実施形態に係る負荷伝達機構部１Ｅの連結関節部１２として用いることができる。
　この場合、負荷伝達機構部１Ａ、１Ｃ、１Ｄ、及び１Ｅは、第１変形例１Ｂａと同様の効果を得ることができ、連結片部３０の１部にボールジョイント４２を用いることで、連結関節部１２の曲がり具合が滑らかになり、主動軸部４の回転及び水平移動をより滑らかに摺動軸部１３、１４、１５に伝えることができる。 In the connecting joint part 12 of the first modification 1Ba, by using a ball joint 42 in a part of the connecting piece part 30, the bending condition of the connecting joint part 12 becomes smooth, and the rotation and horizontal movement of the driving shaft part 4 are controlled. This can be transmitted to the sliding shaft portion 13 more smoothly.
In addition, the connection joint part 12 of the first modification 1Ba includes a load transmission mechanism part 1A according to the first embodiment, a load transmission mechanism part 1C according to the third embodiment, a load transmission mechanism part 1D according to the fourth embodiment, And it can be used as the connecting joint part 12 of the load transmission mechanism part 1E according to the fifth embodiment.
In this case, the load transmission mechanism parts 1A, 1C, 1D, and 1E can obtain the same effect as the first modification 1Ba, and by using the ball joint 42 in a part of the connecting piece part 30, the connecting joint The bending of the portion 12 becomes smoother, and the rotation and horizontal movement of the main drive shaft portion 4 can be more smoothly transmitted to the sliding shaft portions 13, 14, and 15.
＜第２実施形態に係るトレーニング器具用負荷伝達機構部１Ｂの第２変形例１Ｂｂ＞
　次に図３２を参照して負荷伝達機構部１Ｂの第２変形例１Ｂｂについて説明する。図３２において、第２変形例１Ｂｂ（図３２参照）と負荷伝達機構部１Ｂ（図１２、図１３参照）との共通する部分については負荷伝達機構部１Ｂ（図１２、図１３参照）に用いた符号を付すものとし、その説明は省略する。以下、第２変形例１Ｂｂについて負荷伝達機構部１Ｂと異なる部分についてのみ説明する。 <Second modification 1Bb of load transmission mechanism section 1B for training equipment according to second embodiment>
Next, a second modification 1Bb of the load transmission mechanism section 1B will be described with reference to FIG. 32. In FIG. 32, the common parts of the second modification 1Bb (see FIG. 32) and the load transfer mechanism section 1B (see FIGS. 12 and 13) are applicable to the load transfer mechanism section 1B (see FIGS. 12 and 13). The description thereof will be omitted. Hereinafter, only the portions of the second modification 1Bb that are different from the load transmission mechanism section 1B will be described.
　第２変形例１Ｂｂのクランク軸部９と負荷伝達機構部１Ｂのクランク軸部６とにおいて、連結関節部１２との連結位置が異なる。第２変形例１Ｂｂのクランク軸部９の基端部と連結関節部１２の連結位置との距離は、負荷伝達機構部１Ｂのクランク軸部６の基端部と連結関節部１２の連結位置との距離より大きい（図１２、図３２参照）。この違いは、第２変形例１Ｂｂと負荷伝達機構部１Ｂとの初期姿勢の違いに現れる。具体的には、第２変形例１Ｂｂの初期姿勢は図３２における主動軸部４（握持部１１）が一番左に位置している状態であり、負荷伝達機構部１Ｂの初期姿勢は図１２における主動軸部４（握持部１１）が一番右に位置している状態である。 The connection position with the connecting joint part 12 is different between the crankshaft part 9 of the second modification 1Bb and the crankshaft part 6 of the load transmission mechanism part 1B. The distance between the base end of the crankshaft section 9 and the connection position of the connection joint section 12 of the second modification 1Bb is the same as the distance between the base end of the crankshaft section 6 of the load transmission mechanism section 1B and the connection position of the connection joint section 12. (see FIGS. 12 and 32). This difference appears in the difference in initial posture between the second modified example 1Bb and the load transmission mechanism section 1B. Specifically, the initial posture of the second modified example 1Bb is such that the main drive shaft portion 4 (grip portion 11) is located at the far left in FIG. 32, and the initial posture of the load transmission mechanism portion 1B is as shown in FIG. In this state, the main drive shaft portion 4 (grip portion 11) at 12 is located at the far right.
　更に、第２変形例１Ｂｂと負荷伝達機構部１Ｂとでは、主動軸部４の負荷が加わる水平移動の方向が異なる。負荷伝達機構部１Ｂは、初期姿勢（図１２において一番右）から主動軸部４（握持部１１）が摺動軸部１３から遠ざかる方向（図１２において左方向）に移動する際に、移動する方向とは反対方向（図１２において右方向）の負荷が加わる。そして、主動軸部４（握持部１１）が摺動軸部１３に近づく方向（図１２において右方向）に移動する際に、移動する方向と同じ方向（図１２において右方向）に負荷が加わる。 Further, the second modification 1Bb and the load transmission mechanism section 1B differ in the direction of horizontal movement in which the load of the main drive shaft section 4 is applied. When the main drive shaft section 4 (grip section 11) moves away from the sliding shaft section 13 (leftward direction in FIG. 12) from the initial posture (rightmost position in FIG. 12), the load transmission mechanism section 1B A load is applied in the direction opposite to the direction of movement (rightward in FIG. 12). When the main drive shaft portion 4 (grip portion 11) moves in a direction approaching the sliding shaft portion 13 (rightward in FIG. 12), a load is applied in the same direction as the moving direction (rightward in FIG. 12). join.
　一方で、第２変形例１Ｂｂは、初期姿勢（図３２において一番左）から主動軸部４（握持部１１）が摺動軸部１３に近づく方向（図３２において右方向）に移動する際に、移動する方向とは反対方向（図３２において左方向）の負荷が加わる。そして、主動軸部４（握持部１１）が摺動軸部１３から遠ざかる方向（図３２において左方向）に移動する際に、移動する方向と同じ方向（図３２において左方向）に負荷が加わる。 On the other hand, in the second modification 1Bb, the main drive shaft portion 4 (grip portion 11) moves in the direction approaching the sliding shaft portion 13 (to the right in FIG. 32) from the initial posture (leftmost in FIG. 32). At this time, a load is applied in the direction opposite to the direction of movement (leftward in FIG. 32). When the main drive shaft section 4 (grip section 11) moves away from the sliding shaft section 13 (to the left in FIG. 32), a load is applied in the same direction as the moving direction (to the left in FIG. 32). join.
　第２変形例１Ｂｂと負荷伝達機構部１Ｂとでは、同一の動作に対する負荷の加わる方向が正反対となるため、両者を併用することで多種多様な筋力トレーニングを行うことができる。 The second modification 1Bb and the load transmission mechanism section 1B apply loads in opposite directions for the same motion, so by using both in combination, a wide variety of muscle strength training can be performed.
＜第３実施形態に係るトレーニング器具用負荷伝達機構部１Ｃ＞
　図１４ないし１６及び図１８を参照して、第３実施形態のトレーニング器具用負荷伝達機構部１Ｃ（以下負荷伝達機構部１Ｃとする。）の構成及び動作について説明する。図１４は負荷伝達機構部１Ｃの構成を説明するための図であり、図１５は負荷伝達機構部１Ｃの主動軸部２７６の回動及び平行移動を伴う動作を説明するための第１図であり、図１６は同第２図であり、図１８は第２トレーニング器具２０１の足置き部２７１の拡大図である。負荷伝達機構部１Ｃは後述する第２トレーニング器具２０１に接続されて使用される。 <Load transmission mechanism section 1C for training equipment according to third embodiment>
With reference to FIGS. 14 to 16 and FIG. 18, the configuration and operation of a training device load transfer mechanism section 1C (hereinafter referred to as load transfer mechanism section 1C) of the third embodiment will be described. FIG. 14 is a diagram for explaining the configuration of the load transmission mechanism section 1C, and FIG. 15 is a first diagram for explaining the operation involving rotation and parallel movement of the main drive shaft section 276 of the load transmission mechanism section 1C. 16 is the same FIG. 2, and FIG. 18 is an enlarged view of the footrest 271 of the second training device 201. The load transmission mechanism section 1C is used while being connected to a second training device 201, which will be described later.
　負荷伝達機構部１Ｃは主動軸部２７６にユーザの力の入力部となる足置き部２７１が接続される。負荷伝達機構部１Ｃは、第１実施形態に係る負荷伝達機構部１Ａと比較して、主動軸部２７６の構成において負荷伝達機構部１Ａの主動軸部４（図１参照）と異なる。主動軸部２７６は、摺動軸部１３と同じ側面にその端部を突出させており、当該端部に足置き部２７１が接続されている点で負荷伝達機構部１Ａと異なる。以下、負荷伝達機構部１Ｃの説明では、第１実施形態に係る負荷伝達機構部１Ａと共通する構成については図１４ないし１６及び図１８において負荷伝達機構部１Ａの説明に用いた符号を付してその説明を省略し、第１実施形態に係る負荷伝達機構部１Ａと異なる構成についてのみ詳細に説明する。 In the load transmission mechanism section 1C, a footrest section 271 that serves as a user's force input section is connected to a main drive shaft section 276. The load transfer mechanism section 1C is different from the load transfer mechanism section 1A according to the first embodiment in the configuration of the main drive shaft section 276 from the main drive shaft section 4 of the load transfer mechanism section 1A (see FIG. 1). The main drive shaft section 276 differs from the load transmission mechanism section 1A in that its end portion protrudes from the same side as the sliding shaft section 13, and the footrest section 271 is connected to the end section. Hereinafter, in the description of the load transfer mechanism section 1C, the same components as the load transfer mechanism section 1A according to the first embodiment are designated by the reference numerals used in the explanation of the load transfer mechanism section 1A in FIGS. 14 to 16 and FIG. 18. The explanation thereof will be omitted, and only the configuration that is different from the load transmission mechanism section 1A according to the first embodiment will be explained in detail.
　負荷伝達機構部１Ｃは、第１実施形態に係る負荷伝達機構部１Ａ（図１参照）から９０度回転させて、クランク軸部６の軸方向がほぼ鉛直となるように立てた状態で使用される。本体上部２７７付近に主動軸部２７６が位置する。 The load transmission mechanism section 1C is rotated 90 degrees from the load transmission mechanism section 1A (see FIG. 1) according to the first embodiment and used in an upright position so that the axial direction of the crankshaft section 6 is substantially vertical. Ru. The main drive shaft portion 276 is located near the upper portion 277 of the main body.
　ユーザは、左右の何れかの足を足置き部２７１に載せる。足置き部２７１はユーザの足の大きさより一回り大きい面積を持つ。足置き部２７１は、第３回動軸２７３と、側板２７４ａと、側板２７４ｂと、接続板２７５と、を備える。 The user places either the left or right foot on the footrest 271. The footrest 271 has an area that is one size larger than the user's foot. The footrest 271 includes a third rotation shaft 273, a side plate 274a, a side plate 274b, and a connection plate 275.
　接続板２７５は、その中央部に対して垂直に主動軸部２７６が接続される。接続板２７５の両端には、接続板２７５に対して垂直に接続された平板状の側板２７４ａ、２７４ｂが設けられる。側板２７４ａ、２７４ｂには、第３回動軸２７３が回動自在に垂直に接続される。 A driving shaft portion 276 is connected perpendicularly to the center of the connecting plate 275. At both ends of the connection plate 275, flat side plates 274a and 274b connected perpendicularly to the connection plate 275 are provided. A third rotation shaft 273 is vertically and rotatably connected to the side plates 274a and 274b.
　第３回動軸２７３は、足置き部２７１の裏面に設けられた軸受２７２（図１８参照）により回動自在に軸支されている。これにより、足置き部２７１は、第３回動軸２７３回りに回動することができる。また、足置き部２７１は、主動軸部２７６回りに回動することができる。 The third rotation shaft 273 is rotatably supported by a bearing 272 (see FIG. 18) provided on the back surface of the footrest 271. Thereby, the footrest portion 271 can rotate around the third rotation axis 273. Further, the footrest portion 271 can rotate around the main drive shaft portion 276.
　即ち、足置き部２７１は、二つの互いに直交する異なる軸回りに回動することができる。したがって、図１４、１８に示す構造を備えることにより、ユーザは、足の向き及び足の曲げ角など足の置き方の自由度が広がり、ストレスフリーで足置き部２７１に足裏を載置して、自身の足を所望の角度で足置き部２７１を足で押すことができる。よって、ユーザは自身の望む形（角度や力）で、第２トレーニング器具２０１により、足を含む自身の身体に対して負荷を与えることができる。 That is, the footrest 271 can rotate around two mutually orthogonal different axes. Therefore, by providing the structures shown in FIGS. 14 and 18, the user has greater freedom in how to place the foot, such as the direction of the foot and the bending angle of the foot, and can place the sole of the foot on the footrest 271 stress-free. The user can press the footrest 271 with his/her foot at a desired angle. Therefore, the user can use the second training device 201 to apply a load to his or her body, including the feet, in a manner desired by the user (angle or force).
＜第３実施形態に係るトレーニング器具用負荷伝達機構部１Ｃの動作についての説明＞
　ユーザは負荷伝達機構部１Ｃを用いて様々な脚の運動をすることができる。図１４ないし１６を参照し、以下に脚の運動の一例を示しながら負荷伝達機構部１Ｃの動作について説明する。脚の運動の一例として、ユーザの膝関節を屈伸させる運動に伴う、負荷伝達機構部１Ｃの動作について説明する。 <Description of the operation of the training device load transmission mechanism section 1C according to the third embodiment>
The user can perform various leg exercises using the load transmission mechanism section 1C. Referring to FIGS. 14 to 16, the operation of the load transmission mechanism section 1C will be described below while showing an example of leg movement. As an example of leg movement, the operation of the load transmission mechanism section 1C accompanying the movement of bending and extending the user's knee joint will be described.
　ユーザの初期姿勢として膝関節を屈曲させて足の甲を真っ直ぐ上方に向けて足置き部２７１に置く姿勢をとる（図１９参照）。このときの足置き部２７１の状態は、図１４に示す様に足置き部２７１は負荷伝達機構部１Ｃの最上部に位置するとともに、足置き部２７１の向き、延いてはユーザの足の向きは甲を真っ直ぐ上方に向けた状態にある。図１４に示す状態では摺動軸部１３は外側筐体２の外部に最大限出ている。 The user's initial posture is to bend the knee joint and place the foot on the footrest 271 with the top of the foot facing straight upwards (see FIG. 19). The state of the footrest 271 at this time is such that the footrest 271 is located at the top of the load transmission mechanism 1C as shown in FIG. with the instep facing straight upwards. In the state shown in FIG. 14, the sliding shaft portion 13 is exposed to the outside of the outer housing 2 to the maximum extent possible.
　次に、ユーザは膝関節を徐々に伸ばしつつ、当該膝関節を内側に倒すようにして脚を回転させる（図２０、２１参照）。ユーザは膝関節を伸ばす際に脚を斜め上方に押し上げるようにして足置き部２７１を押し上げることで足置き部２７１を上方へ平行移動させる。膝関節を最大限開いた状態において、ユーザは膝関節を内側に最大限倒すようにする（図２１参照）。このときの足置き部２７１の状態は、図１６に示すように足置き部２７１は負荷伝達機構部１Ｃの最上部に位置するとともに、足置き部２７１は主動軸部２７６の軸周りを最大限回動した状態にある。図１６に示す状態では摺動軸部１３は外側筐体２の内部に最大限引き込まれている。 Next, the user rotates the leg while gradually stretching the knee joint and tilting the knee joint inward (see FIGS. 20 and 21). The user moves the footrest 271 upward in parallel by pushing up the footrest 271 as if pushing the leg diagonally upward when extending the knee joint. With the knee joint fully open, the user tilts the knee joint inward as much as possible (see FIG. 21). At this time, the footrest 271 is positioned at the top of the load transmission mechanism 1C as shown in FIG. It is in a rotating state. In the state shown in FIG. 16, the sliding shaft portion 13 is pulled into the outer housing 2 to the maximum extent.
　負荷伝達機構部１Ｃの状態において、図１５は図１４に示す状態から図１６に示す状態へ移行する途中の状態を示す。 In the state of the load transmission mechanism section 1C, FIG. 15 shows a state in the middle of transition from the state shown in FIG. 14 to the state shown in FIG. 16.
　負荷伝達機構部１Ｃにおいて、足置き部２７１を回動することで、主動軸部２７６の回動が第１回動伝達部１Ｋ、第２回動伝達部１Ｍ、連結関節部１２を介して摺動軸部１３に伝達され、摺動軸部１３は外側筐体２に対して相対的に変位し、当該変位が負荷付与部２３０のウェイトを上下に変位させる。ユーザは、負荷付与部２３０により生じる付勢力に抗いながら足置き部２７１の回動運動を行うことができる。 In the load transmission mechanism section 1C, by rotating the foot rest section 271, the rotation of the main drive shaft section 276 is caused to slide through the first rotation transmission section 1K, the second rotation transmission section 1M, and the connecting joint section 12. This is transmitted to the dynamic shaft portion 13, and the sliding shaft portion 13 is displaced relative to the outer housing 2, and this displacement vertically displaces the weight of the load applying portion 230. The user can rotate the footrest 271 while resisting the urging force generated by the load applying section 230.
　さらに、負荷伝達機構部１Ｃにおいて、足置き部２７１を図１４中における上方に平行移動させることで、主動軸部２７６の平行移動が内側筐体３及び連結関節部１２を介して摺動軸部１３に伝達され、摺動軸部１３は外側筐体２に対して相対的に変位し、当該変位が負荷付与部２３０のウェイトを上下に変位させる。ユーザは、負荷付与部２３０により生じる付勢力に抗いながら足置き部２７１の平行移動を行うことができる。 Furthermore, in the load transmission mechanism section 1C, by moving the footrest section 271 upward in parallel in FIG. 13, the sliding shaft portion 13 is displaced relative to the outer housing 2, and this displacement vertically displaces the weight of the load applying portion 230. The user can move the footrest section 271 in parallel while resisting the urging force generated by the load applying section 230.
　なお、図１５に示す負荷伝達機構部１Ｃの状態では、負荷付与部１３０のウェイトの負荷の作用により図１４に示す初期状態に戻ろうとする力（復元力）が足置き部２７１に作用する。ユーザはこの復元力に抗いながら図１５の状態を維持するか、足置き部２７１をさらに回動若しくは平行移動させるか（図１６参照）、又は初期姿勢の状態に戻すこととなる（図１４参照）。 Note that in the state of the load transmission mechanism section 1C shown in FIG. 15, a force (restoring force) that attempts to return to the initial state shown in FIG. 14 acts on the foot rest section 271 due to the action of the load of the weight of the load applying section 130. The user either maintains the state shown in FIG. 15 while resisting this restoring force, further rotates or translates the footrest 271 (see FIG. 16), or returns to the initial posture (see FIG. 14). ).
　＜第２トレーニング器具２０１＞
　図１７ないし２１を参照して第２トレーニング器具２０１の構成及び動作について説明する。図１７は、第２トレーニング器具２０１の外観を示す斜視図である。
　＜第２トレーニング器具２０１の構成についての説明＞
　図１７に示すように、第２トレーニング器具２０１は、ユーザが着座するための着座部２１０と、負荷を付与する負荷付与部２３０と、鉛直方向に伸びる円柱状の案内支柱２４０と、案内支柱２４０に案内されて上下方向に移動自在、かつ、回動自在に接続された昇降部２５０と、昇降部２５０に設けられた把持部２６０と、ユーザの足裏を載置するための足置き部２７１と、スライドレール２２２ａ、２２２ｂと、足置き部２７１を備える負荷伝達機構部１Ｃと、一端が昇降部２５０に接続され、他端が負荷伝達機構部１Ｃに接続され、負荷付与部２３０による負荷を昇降部２５０及び負荷伝達機構部１Ｃに対して付与する引張部材２８０と、を備える。
　昇降部２５０は、トレーニング器具用負荷伝達機構部１Ａ、トレーニング器具用負荷伝達機構部１Ｂ、及び、後述のトレーニング器具用負荷伝達機構部１Ｄ、トレーニング器具用負荷伝達機構部１Ｅを適用し用いることができる。把持部２６０は、トレーニング器具用負荷伝達機構部１Ａ、トレーニング器具用負荷伝達機構部１Ｂ、及び、後述のトレーニング器具用負荷伝達機構部１Ｄ、トレーニング器具用負荷伝達機構部１Ｅの握持部１１に相当し、ユーザが力を入力する入力部である。 <Second training equipment 201>
The configuration and operation of the second training device 201 will be explained with reference to FIGS. 17 to 21. FIG. 17 is a perspective view showing the appearance of the second training device 201. As shown in FIG.
<Description of the configuration of the second training device 201>
As shown in FIG. 17, the second training device 201 includes a seating section 210 for a user to sit on, a load applying section 230 for applying a load, a cylindrical guide column 240 extending in the vertical direction, and a guide column 240. an elevating section 250 that is guided by and connected to the elevating section so as to be movable and rotatable in the vertical direction; a grip section 260 provided on the elevating section 250; and a foot rest section 271 for placing the sole of the user's foot. and a load transmission mechanism section 1C including slide rails 222a, 222b and a foot rest section 271, one end of which is connected to the elevating section 250 and the other end of which is connected to the load transmission mechanism section 1C, which allows the load by the load application section 230 to be transferred. It includes a tension member 280 that is applied to the lifting section 250 and the load transmission mechanism section 1C.
The elevating section 250 can apply and use a training equipment load transmission mechanism part 1A, a training equipment load transmission mechanism part 1B, a training equipment load transmission mechanism part 1D, and a training equipment load transmission mechanism part 1E, which will be described later. can. The grip part 260 is attached to the grip part 11 of the training equipment load transmission mechanism part 1A, the training equipment load transmission mechanism part 1B, the training equipment load transmission mechanism part 1D, and the training equipment load transmission mechanism part 1E, which will be described later. This corresponds to an input section through which the user inputs force.
　以下、第２トレーニング器具２０１について図面を用いて詳細に説明する。まず、図１７、図１８を用いて、第２トレーニング器具２０１の構造を説明する。図１７は、前述の通り、第２トレーニング器具２０１の斜視図であり、図１８は、負荷伝達機構部１Ｃ周りの拡大図である。 Hereinafter, the second training device 201 will be explained in detail using the drawings. First, the structure of the second training device 201 will be explained using FIGS. 17 and 18. As described above, FIG. 17 is a perspective view of the second training device 201, and FIG. 18 is an enlarged view of the area around the load transmission mechanism section 1C.
　図１７に示されるように、第２トレーニング器具２０１において、着座部２１０は、第２トレーニング器具２０１の基礎フレームとなる枠組２２０により支持される。枠組２２０は、第２トレーニング器具２０１全体の骨格となり、第２トレーニング器具２０１を床面に安定させて設置させる機能を担う。枠組２２０は、例えば、鉄鋼やアルミニウム、ステンレス、樹脂等の一定以上の剛性を有する素材からなる角柱パイプ材や板材などを加工して、ボルトや溶接等により固定して形成することができる。着座部２１０は、ユーザが着座する座席２１１と、座席２１１を支持する座席支柱２１２と、から成る。座席支柱２１２は、枠組２２０に対して固定される。そして、座席支柱２１２は、座席２１１を保持する。座席支柱２１２は、図示していないが、引張部材２８０を前後方向に通過させるための貫通孔を備える。座席２１１は、第２トレーニング器具２０１の使用者（ユーザ）が着座する箇所であり、図１７に示すように、第２トレーニング器具２０１の左右方向に長い長方形となっている。これは、座席２１１の右側と左側のいずれにも着座できるようにするためであるが、ユーザが無理なく着座できるのであれば長方形でなくともよく、正方形であってもよいし、円形であってもよい。 As shown in FIG. 17, in the second training device 201, the seating portion 210 is supported by a framework 220 that serves as the base frame of the second training device 201. The framework 220 serves as the skeleton of the entire second training device 201, and has the function of stably installing the second training device 201 on the floor. The frame 220 can be formed by, for example, processing a prismatic pipe or plate made of a material having a certain level of rigidity, such as steel, aluminum, stainless steel, or resin, and fixing the material with bolts, welding, or the like. The seating section 210 includes a seat 211 on which a user sits, and a seat support 212 that supports the seat 211. Seat post 212 is fixed to framework 220. The seat support 212 then holds the seat 211. Although not shown, the seat support column 212 includes a through hole through which the tension member 280 passes in the front-rear direction. The seat 211 is a place where the user of the second training device 201 sits, and has a rectangular shape that is long in the left-right direction of the second training device 201, as shown in FIG. This is to allow the user to sit on either the right or left side of the seat 211, but it does not need to be rectangular as long as the user can sit comfortably, and may be square or circular. Good too.
　図１７に示すように、着座部２１０は、座席２１１の後方であって、負荷付与部２３０との間に、ユーザが使用時に体を支持させるための背もたれ２１５を備えてもよい。 As shown in FIG. 17, the seating section 210 may include a backrest 215 behind the seat 211 and between it and the load applying section 230 for supporting the user's body during use.
　枠組２２０には、鉛直方向に伸びる案内支柱２４０が設けられる。図１７に示されるように、案内支柱２４０は、負荷付与部２３０よりも前方、かつ、着座部２１０よりも後方の位置に設けられる。図１７に示されるように、枠組２２０は、案内支柱２４０の後方に、内部で、引張部材２８０の伸長方向を誘導するための上部筐体２２５を備える。そして、案内支柱２４０は、その下端が枠組２２０に接続され、上端が上部筐体２２５に接続されて固定される。 The framework 220 is provided with a guide column 240 that extends in the vertical direction. As shown in FIG. 17, the guide column 240 is provided at a position forward of the load application section 230 and rearward of the seating section 210. As shown in FIG. 17 , the framework 220 includes an upper housing 225 for guiding the extension direction of the tension member 280 internally behind the guide column 240 . The lower end of the guide column 240 is connected to the framework 220, and the upper end is connected to and fixed to the upper housing 225.
　図１７に示されるように、案内支柱２４０には衝撃吸収材２４１が設けられてもよい。衝撃吸収材２４１は、昇降部２５０が、上部筐体２２５及び枠組２２０に対して、接触する際の衝撃を緩和するための部材である。衝撃吸収材２４１は、一例としてゴムやスポンジ等により実現されてもよい。 As shown in FIG. 17, the guide column 240 may be provided with a shock absorber 241. The shock absorber 241 is a member for alleviating the shock when the elevating section 250 comes into contact with the upper housing 225 and the framework 220. The shock absorber 241 may be realized by rubber, sponge, or the like, for example.
　案内支柱２４０には、図１７に示される昇降部２５０が取り付けられる。図１７に示されるように、昇降部２５０は、案内支柱２４０に対して上下移動自在に取り付けられている。図示していないが、昇降部２５０は、案内支柱２４０を挿通するための貫通孔を有する。したがって、昇降部２５０は、案内支柱２４０に沿って上下移動する。また、昇降部２５０は、案内支柱２４０を中心軸として、案内支柱２４０に対して回動自在に、案内支柱２４０に取り付けられている。したがって、案内支柱２４０には一定の剛性が求められる。よって、案内支柱２４０は、一例として、ステンレス等により作製されてよい。第２トレーニング器具２０１において、昇降部２５０として、前出の第１実施形態に係る負荷伝達機構部１Ａ、第２実施形態に係る負荷伝達機構部１Ｂ、後述の第４実施形態に係る負荷伝達機構部１Ｄ、または第５実施形態に係る負荷伝達機構部１Ｅが適用されるようにしても良い。 An elevating section 250 shown in FIG. 17 is attached to the guide column 240. As shown in FIG. 17, the elevating section 250 is attached to the guide column 240 so as to be movable up and down. Although not shown, the elevating section 250 has a through hole through which the guide column 240 is inserted. Therefore, the elevating section 250 moves up and down along the guide column 240. Further, the elevating section 250 is attached to the guide column 240 so as to be rotatable with respect to the guide column 240 with the guide column 240 as a central axis. Therefore, the guide column 240 is required to have a certain degree of rigidity. Therefore, the guide column 240 may be made of stainless steel or the like, for example. In the second training device 201, the lifting section 250 includes a load transmission mechanism section 1A according to the first embodiment described above, a load transmission mechanism section 1B according to the second embodiment, and a load transmission mechanism according to the fourth embodiment described below. The portion 1D or the load transmission mechanism portion 1E according to the fifth embodiment may be applied.
　図１７に示されるように、第２トレーニング器具２０１の負荷伝達機構部１Ｃは、スライドレール２２２ａ、２２２ｂに沿って摺動する。そのスライドレール２２２ａは、第２トレーニング器具２０１の枠組２２０と枠組２２０の前方に配される枠組２２１に懸架され、両端部で固定される。図１８は、第２トレーニング器具２０１のうちの負荷伝達機構部１Ｃ周りの拡大図である。 As shown in FIG. 17, the load transmission mechanism section 1C of the second training device 201 slides along the slide rails 222a and 222b. The slide rail 222a is suspended by a framework 220 of the second training device 201 and a framework 221 disposed in front of the framework 220, and is fixed at both ends. FIG. 18 is an enlarged view of the load transmission mechanism section 1C of the second training device 201.
　負荷付与部２３０は、図１７に示すように、枠組２２０に対してその上下が固定された一対の円柱状のウェイト案内支柱２３２（図１７では紙面の関係上片方のみを示している）と、ウェイト案内支柱２３２に対して上下動自在に構成されたウェイトとからなる。ウェイトにはウェイト案内支柱２３２を挿通するための貫通孔が設けられている。負荷付与部２３０は、付与する負荷の大きさを調整可能に構成されてよく、具体的には、重量部材となるウェイトを板状の部材とし、その枚数によって、負荷を調整することとしてよい。したがって、負荷付与部２３０は、ウェイトを相互に連結離別自在とするクランプ（不図示）を備えることとしてもよい。ウェイトの板状の部材それぞれを固定の重量とすることで、段階的に負荷の大きさを変更することができる。また、ウェイト案内支柱２３２には、衝撃吸収材２３１が設けられてよく、ウェイトが枠組２２０と一定以上の衝撃を以て衝突することを抑制する。 As shown in FIG. 17, the load applying section 230 includes a pair of cylindrical weight guide columns 232 (only one of which is shown due to space constraints in FIG. 17) whose top and bottom are fixed to the framework 220; The weight is configured to be movable up and down relative to the weight guide column 232. The weight is provided with a through hole through which the weight guide column 232 is inserted. The load applying section 230 may be configured to be able to adjust the magnitude of the load to be applied. Specifically, the weight serving as the weight member may be a plate-shaped member, and the load may be adjusted depending on the number of the weights. Therefore, the load applying section 230 may include a clamp (not shown) that connects and detaches the weights from each other. By setting each plate-shaped member of the weight to a fixed weight, the magnitude of the load can be changed in stages. Further, the weight guide column 232 may be provided with a shock absorbing material 231 to prevent the weight from colliding with the framework 220 with a shock exceeding a certain level.
　＜第２トレーニング器具２０１の使用方法＞
　図１９ないし２１を参照して、第２トレーニング器具２０１の使用方法について説明する。図１９～図２１は、第２トレーニング器具２０１を使用する運動の例であって、足の運動をする例を示す左側面図である。 <How to use the second training device 201>
A method of using the second training device 201 will be described with reference to FIGS. 19 to 21. FIGS. 19 to 21 are left side views showing examples of exercises using the second training device 201, including an example of exercising the legs.
　図１９に示すように、ユーザは、第２トレーニング器具２０１の右側、即ち、座席２１１の右側に着座する（図１９の紙面上手前側）。即ち、ユーザは、負荷伝達機構部１Ｃを左側、背もたれ２１５を右側にして、座席２１１に着座する。そして、図１９に示すように、ユーザは、左脚を負荷伝達機構部１Ｃの足置き部２７１に載置し、ひざを屈曲させた状態をとる。 As shown in FIG. 19, the user is seated on the right side of the second training device 201, that is, on the right side of the seat 211 (upper front side in the paper of FIG. 19). That is, the user sits on the seat 211 with the load transmission mechanism section 1C on the left side and the backrest 215 on the right side. Then, as shown in FIG. 19, the user places his left leg on the footrest 271 of the load transmission mechanism section 1C and bends his knee.
　この状態から、ユーザは、左足を伸ばしていき、負荷伝達機構部１Ｃを押す。すると、図２０に示すように、負荷伝達機構部１Ｃは、スライドレール２２２ａ、２２２ｂに沿って摺動していく。このとき、負荷伝達機構部１Ｃには、第２トレーニング器具２０１後方（図１９～図２１の紙面左方向）に向けて、接続部２７９に接続された引張部材２８０に接続された負荷付与部２３０の負荷が付与される。 From this state, the user stretches his left leg and pushes the load transmission mechanism section 1C. Then, as shown in FIG. 20, the load transmission mechanism section 1C slides along the slide rails 222a and 222b. At this time, the load transmission mechanism section 1C includes a load application section 230 connected to the tension member 280 connected to the connection section 279 toward the rear of the second training device 201 (leftward in the paper plane of FIGS. 19 to 21). load is given.
　そして、図２０に示すように足を伸ばした状態から、ゆっくりと負荷伝達機構部１Ｃをスライドレール２２２ａ、２２２ｂに沿って、元の位置に戻すように摺動させる。この運動を一定回数繰り返し実行する。つまり、ユーザは、図１９と図２０との間の姿勢を所定回数繰り返す。 Then, as shown in FIG. 20, from the state where the legs are extended, the load transmission mechanism section 1C is slowly slid along the slide rails 222a and 222b so as to return to its original position. Repeat this exercise a certain number of times. That is, the user repeats the posture between FIG. 19 and FIG. 20 a predetermined number of times.
　なお、ユーザは、図２１に示すように、図２０に示す状態よりも更に腰に捻りを加える方法で、負荷伝達機構部１Ｃをより遠くまで押してもよく、その場合により足を伸ばしつつ腰回りを鍛えることができる。このような姿勢が可能なのも、足置き部２７１が、負荷伝達機構部１Ｃ本体に対して回動自在に構成されているからである。ユーザは、図１９と図２０の間で足の伸縮運動を行ってもよいし、図１９と図２１の間で足の伸縮運動を行ってもよい。 In addition, as shown in FIG. 21, the user may push the load transmission mechanism part 1C further by twisting the waist further than in the state shown in FIG. can be trained. This posture is possible because the footrest 271 is configured to be rotatable relative to the main body of the load transmission mechanism 1C. The user may extend/contract the legs between FIG. 19 and FIG. 20, or may extend/contract the legs between FIG. 19 and FIG. 21.
　また、図示していないが、図１９～図２１における座席２１１の反対側であって第２トレーニング器具２０１の左側に着座する（図１９～２１の紙面上奥側）。即ちユーザが自身の右側に負荷伝達機構部１Ｃを左側に背もたれ２１５が位置するように座席２１１に着座することで、ユーザは右足による運動をすることもできる。 Although not shown, the user is seated on the opposite side of the seat 211 in FIGS. 19 to 21 and on the left side of the second training device 201 (the back side on the paper of FIGS. 19 to 21). That is, by sitting on the seat 211 with the load transmission mechanism section 1C on the right side of the user and the backrest 215 on the left side, the user can also exercise with his or her right leg.
　したがって、左右対称に、ユーザは、両足を鍛えつつ、腰回りの回転運動を行うことができる。具体的には、ユーザは開脚して負荷伝達機構部１Ｃを蹴るようにして押し出す動作を行う。このため、ユーザの股関節周り、骨盤の周囲、大腿部、膝等の筋肉の強化に好例である。 Therefore, the user can perform rotational exercise around the waist while training both legs symmetrically. Specifically, the user opens his legs and performs a kicking motion to push out the load transmission mechanism section 1C. Therefore, it is a good example for strengthening muscles around the user's hip joints, pelvis, thighs, knees, etc.
　脚の各筋肉群が「弛緩－伸長－短縮」のタイミングを得て、連動性よく動作を行うことができる。具体的には、図１９に示す状態では、左足には負荷付与部２３０の負荷がかからず、筋肉が「伸長」している状態であると言える。また、図１９に示す状態は、足置き部２７１に、ただ、足を載置しているだけの状態でもあり、全体的にリラックスした状態であるので、「弛緩」している状態であるとも言える。 Each muscle group in the legs can achieve the timing of "relaxation-stretching-shortening" and perform movements in a well-coordinated manner. Specifically, in the state shown in FIG. 19, no load is applied to the left leg by the load applying section 230, and the muscles can be said to be in a "stretched" state. In addition, the state shown in FIG. 19 is a state in which the feet are simply placed on the foot rest portion 271, and is in an overall relaxed state, so it can be said to be a "relaxed" state. I can say it.
　ここから、ユーザが、足に力を加えて、負荷付与部２３０による負荷が加えられている負荷伝達機構部１Ｃを押していく。即ち、図１９から図２０又は図２１に示す過程において、ユーザの左脚に負荷付与部２３０の負荷がかかり、ユーザの左脚の筋肉に、「短縮」状態を生じさせることができる。そして、図２０又は図２１に示す状態において、足置き部２７１を負荷伝達機構部１Ｃに対して回転させることで、内部のクランク機構により接続部２７９が負荷伝達機構部１Ｃ内に引き込まれることによって、足にかかる負荷付与部２３０による負荷が加重される。即ち、図２０又は図２１に示すように、負荷伝達機構部１Ｃを回転させる状態では、ユーザの足に、「弛緩」状態を生じさせることができる。 From here, the user applies force to his/her foot to push the load transmission mechanism section 1C to which the load is applied by the load application section 230. That is, in the process shown in FIGS. 19 to 20 or 21, the load applying unit 230 applies a load to the user's left leg, causing the muscles of the user's left leg to be in a “shortened” state. In the state shown in FIG. 20 or 21, by rotating the footrest 271 relative to the load transmission mechanism 1C, the connecting portion 279 is pulled into the load transmission mechanism 1C by the internal crank mechanism. , the load applied to the foot by the load applying section 230 is increased. That is, as shown in FIG. 20 or 21, when the load transmission mechanism section 1C is rotated, the user's feet can be brought into a "relaxed" state.
　そして、図２０や図２１に示す状態から図１９に示す状態に移行する過程において、脚を図１９の状態に戻していくことで、筋肉の「伸長」状態を生じさせることができる。
　したがって、図１９に示す状態から、図２０や図２１に示す状態になるまで、負荷伝達機構部１Ｃを動かし、そこから、図１９に示す状態に戻す運動のサイクルを繰り返すことで、「弛緩－伸長－短縮」のタイミングを生じさせて、連動性よく動作を行うことができる。なお、脚の運動についても、図１９に示す状態を初期状態としてもよいし、図２０や図２１に示す状態を初期状態として１サイクルの運動を行うこととしてもよいが、「弛緩」した状態から運動を開始することが望ましいことから、他者の協力等を得て、図２０や図２１に示す状態から運動を開始することが望ましい。 Then, in the process of transitioning from the state shown in FIGS. 20 and 21 to the state shown in FIG. 19, by returning the leg to the state shown in FIG. 19, the "stretched" state of the muscles can be caused.
Therefore, by repeating the cycle of moving the load transmission mechanism 1C from the state shown in FIG. 19 to the state shown in FIGS. 20 and 21, and then returning it to the state shown in FIG. By creating the timing of "extension-contraction", the movements can be performed in a well-coordinated manner. Regarding the movement of the legs, the state shown in FIG. 19 may be the initial state, or the state shown in FIGS. 20 and 21 may be the initial state and one cycle of movement may be performed, but the "relaxed" state Since it is desirable to start the exercise from the state shown in FIGS. 20 and 21, it is desirable to obtain the cooperation of others and start the exercise from the state shown in FIG. 20 or 21.
　また、両脚ではなく片脚ずつ鍛える構造とすることで、一度に両方を鍛えるための負荷伝達機構部１Ｃを用意する必要がないので、両足に対応する形で第２トレーニング器具２０１を構成するよりもサイズをコンパクトにすることができる（負荷伝達機構部１Ｃを両脚のために二つ備えるよりも幅を狭くすることができる）ので、第２トレーニング器具２０１の設置スペースとして用意するべきスペースの面積を小さくすることができる。なお、図１９～図２０の運動において、ユーザは、第２トレーニング器具２０１に、対して、負荷伝達機構部１Ｃを正面にし、背もたれ２１５を背にして着座部２１０に着座して、運動を行ってもよい。 Moreover, by adopting a structure that trains one leg at a time instead of both legs, there is no need to prepare a load transmission mechanism section 1C for training both legs at once, so it is better to configure the second training device 201 in a form that corresponds to both legs. Since the size can be made compact (the width can be made narrower than when two load transmission mechanism parts 1C are provided for both legs), the area of the space that should be prepared as the installation space for the second training equipment 201 is reduced. can be made smaller. In addition, in the exercise shown in FIGS. 19 to 20, the user performs the exercise while sitting on the second training device 201 on the seat section 210 with the load transmission mechanism section 1C facing forward and the backrest 215 at the back. You can.
　＜第１トレーニング器具１００及び第２トレーニング器具２０１のまとめ＞
　前述の第１トレーニング器具１００及び第２トレーニング器具２０１は、初動負荷トレーニング（登録商標）により肩部、腕部、背部、脚の筋肉等に対するトレーニングを適切に行う器具である。ここで、初動負荷トレーニングとは、「反射の起こるポジションへの身体変化及びそれに伴う重心位置変化等を利用し、主働筋の弛緩－伸張－短縮の一連動作過程を促進させるとともに、その拮抗筋並びに拮抗的に作用する筋の共縮を防ぎながら行うトレーニング」と定義される。初動負荷トレーニングは、最後まで負荷を与えて筋肉の緊張状態（硬化）を伴いながら筋肉を肥大化する終動負荷トレーニングとは全く異なるトレーニングである。初動負荷トレーニングは、負荷を与えるポイント、負荷を解き放つポイントと角度、リズム、筋出力の連続性など全体としての動作イメージを把握してトレーニングを行うことが必要である。従来の負荷トレーニングは身体のバランスや部分的硬化等によって適切な動作やフォームを取ることが困難であるという問題を内包している。しかし、初動負荷トレーニングを実現する第１トレーニング器具１００及び第２トレーニング器具２０１により理想的な一連動作やフォームを伴ったトレーニングが容易に誘導される。 <Summary of the first training device 100 and the second training device 201>
The first training device 100 and the second training device 201 described above are devices that appropriately train muscles of the shoulders, arms, back, legs, etc. through initial load training (registered trademark). Here, initial load training is defined as ``using the body's change to the position where the reflex occurs and the accompanying change in the center of gravity, etc., to promote the series of movements of relaxation, stretching, and shortening of the agonist muscles, and to promote the relaxation, stretching, and shortening of the agonist muscles. It is defined as "training performed while preventing co-contraction of muscles that act antagonistically." Initial load training is a completely different type of training from final load training, in which the load is applied until the end, causing muscle tension (hardening) and increasing the size of the muscles. In initial load training, it is necessary to train with an understanding of the overall movement image, such as the point at which the load is applied, the point and angle at which the load is released, the rhythm, and the continuity of muscle output. Conventional load training involves the problem that it is difficult to maintain proper movement and form due to body balance, partial stiffness, etc. However, the first training device 100 and the second training device 201 that realize initial load training can easily induce training with an ideal series of movements and form.
　第１トレーニング器具１００及び第２トレーニング器具２０１を用いた初動負荷トレーニングによって、「中心部（身体根幹部）から末端部への分節間の力伝達」、すなわち、自らは伸びようとせず縮む特性を持つ人体の筋を弛緩させリラックスした状態とし、感覚受容器である筋紡錘・腱器官に適切な負荷を与え、適度に筋を伸張したところから、あるいは受動的に伸張されたところから筋が短縮する時の力発揮を誘発し、瞬時、連続性をもって負荷が漸減することにより、共縮を起こさないのは心筋だけと言われてきた人体の他の筋が心筋のように共縮を起こすことのない活動状態を得ることができ、神経筋制御を促進・発達させることが可能となる。 Through initial load training using the first training device 100 and the second training device 201, “force transmission between segments from the center (body trunk) to the distal region”, that is, the characteristic of contracting without trying to expand, is achieved. By relaxing the muscles of the human body and placing an appropriate load on the muscle spindles and tendon organs that are sensory receptors, the muscles can be shortened from the point where they are stretched moderately or from the point where they are passively stretched. It is said that the myocardium is the only muscle that does not cause co-contraction, but other muscles in the human body can cause co-contraction like the myocardium. It is possible to obtain a state of activity free of stress, and it becomes possible to promote and develop neuromuscular control.
　第１トレーニング器具１００及び第２トレーニング器具２０１を用いた初動負荷トレーニングは、当該トレーニング器具の負荷を利用して筋肉に反射を起こし、本来働かなければならない筋肉がうまく働き、筋肉と神経の機能を高めるトレーニングである。弛緩した筋肉にタイミングの良い伸縮、短縮を促すための触媒として負荷を用いている。そして、このようなトレーニングによって、弛緩－伸張－短縮の一連動作の促進が図られ、さらに共縮が防止されることにより、神経と筋肉の機能や協調性を高め、筋肉痛や疲労など身体への負担が少なく、筋肉の硬化を伴うことなく、柔軟で弾力性の富んだ筋肉が得られる。又、強制的な心拍数や血圧の上昇が少なく有酸素的に代謝を促進させることにより、糖尿病、高血圧など生活習慣病の予防や靭帯損傷、骨折等の治癒促進に有効であるとともに、神経・筋肉・関節のストレスの解除、老廃物の除去等、身体に有益な状態を作り出すことができる。 Initial load training using the first training device 100 and the second training device 201 uses the load of the training device to cause reflexes in the muscles, so that the muscles that should normally work work well and the functions of muscles and nerves are improved. This is training to improve. Load is used as a catalyst to encourage relaxed muscles to stretch and shorten in a timely manner. This kind of training promotes the series of relaxation-stretching-shortening movements, and prevents co-contraction, thereby improving the function and coordination of nerves and muscles, and reducing physical effects such as muscle pain and fatigue. Flexible and elastic muscles can be obtained with less strain on the muscles and without muscle stiffness. In addition, by aerobically promoting metabolism with less forced increase in heart rate and blood pressure, it is effective in preventing lifestyle-related diseases such as diabetes and hypertension, and promoting healing of ligament damage and fractures, as well as improving nerve and It can create beneficial conditions for the body, such as relieving stress in muscles and joints and removing waste products.

　図３３を参照して負荷伝達機構部１Ｃの変形例１Ｃａについて説明する。変形例１Ｃａは、負荷伝達機構部１Ｃ（図１４、１５、１６参照）に対して、足置き部２７１（主動軸部４）の移動方向が異なる。負荷伝達機構部１Ｃ（図１４、１５、１６参照）において、足置き部２７１（主動軸部４）の移動方向は、摺動軸部１３の移動方向に対して直角となる。即ち、足置き部２７１（主動軸部４）の移動方向と摺動軸部１３の移動方向とのなす角は９０度となる。 In FIG. 33, the common parts of the modification 1Ca (see FIG. 33) and the load transfer mechanism section 1C (see FIGS. 14, 15, and 16) are as follows. The reference numerals used in (see) will be used, and the explanation thereof will be omitted. Hereinafter, only the portions of the modified example 1Ca (see FIG. 33) that are different from the load transmission mechanism section 1C (see FIGS. 14, 15, and 16) will be described.
A modification 1Ca of the load transmission mechanism section 1C will be described with reference to FIG. 33. Modification 1Ca is different from the load transmission mechanism section 1C (see FIGS. 14, 15, and 16) in the moving direction of the foot rest section 271 (main driving shaft section 4). In the load transmission mechanism section 1C (see FIGS. 14, 15, and 16), the moving direction of the footrest section 271 (main driving shaft section 4) is perpendicular to the moving direction of the sliding shaft section 13. That is, the angle formed by the moving direction of the foot rest part 271 (main driving shaft part 4) and the moving direction of the sliding shaft part 13 is 90 degrees.
　これに対して、変形例１Ｃａ（図３３参照）の足置き部２７１（主動軸部４）の移動方向は、摺動軸部１３の移動方向に対して４５度となる。即ち、足置き部２７１（主動軸部４）の移動方向と摺動軸部１３の移動方向とのなす角は４５度となる。 On the other hand, the moving direction of the foot rest part 271 (main driving shaft part 4) of Modification 1Ca (see FIG. 33) is 45 degrees with respect to the moving direction of the sliding shaft part 13. That is, the angle formed by the moving direction of the foot rest part 271 (main driving shaft part 4) and the moving direction of the sliding shaft part 13 is 45 degrees.
　変形例１Ｃａ（図３３参照）は、足置き部２７１（主動軸部４）を斜め上方に移動することができるため、足置き部２７１及び主動軸部４などの重量による負荷を軽減することができ、小さい負荷から大きい負荷まで調整幅を大きくすることができるため利用者が子供、女性及び高齢者など筋力の弱い人でも利用することができる。 In modification 1Ca (see FIG. 33), the footrest 271 (main drive shaft 4) can be moved diagonally upward, so the load due to the weight of the footrest 271, main drive shaft 4, etc. can be reduced. Since the adjustment range can be widened from small to large loads, it can be used even by people with weak muscles such as children, women, and the elderly.
　また、負荷伝達機構部１Ｃにおいて足置き部２７１（主動軸部４）を真上方向に移動させる場合、脚に力が入りにくい場合があるが、変形例１Ｃａは足置き部２７１（主動軸部４）を斜め上方に移動させるので、脚に力が入り易く筋力トレーニングがし易いなどの効果を得ることができる。 Furthermore, when moving the footrest 271 (main drive shaft 4) directly upward in the load transmission mechanism 1C, it may be difficult to apply force to the legs; 4) is moved diagonally upward, so it is possible to obtain effects such as easier force to be applied to the legs and easier muscle training.
＜第４実施形態に係るトレーニング器具用負荷伝達機構部１Ｄ＞
　図２２ないし２４を参照して、第４実施形態のトレーニング器具用負荷伝達機構部１Ｄ（以下負荷伝達機構部１Ｄとする。）の構成及び動作について説明する。図２２は第４実施形態に係るトレーニング器具用負荷伝達機構部１Ｄの構成を説明するための図であり、図２３は第４実施形態に係るトレーニング器具用負荷伝達機構部１Ｄの動作について説明するための図であり、図２４は第４実施形態に係るトレーニング器具用負荷伝達機構部１Ｄに用いられる摺動軸受１４ａを説明するための図である。
　負荷伝達機構部１Ｄは、第１トレーニング器具１００及び第２トレーニング器具２０１に接続されて使用される。 <Load transmission mechanism section 1D for training equipment according to fourth embodiment>
With reference to FIGS. 22 to 24, the configuration and operation of a training device load transmission mechanism section 1D (hereinafter referred to as load transmission mechanism section 1D) of the fourth embodiment will be described. FIG. 22 is a diagram for explaining the configuration of the training equipment load transmission mechanism section 1D according to the fourth embodiment, and FIG. 23 is a diagram for explaining the operation of the training equipment load transmission mechanism section 1D according to the fourth embodiment. FIG. 24 is a diagram for explaining a sliding bearing 14a used in a training device load transmission mechanism 1D according to a fourth embodiment.
The load transmission mechanism section 1D is used while being connected to the first training device 100 and the second training device 201.
　負荷伝達機構部１Ｄの摺動軸受１４ａの構成が第２実施形態に係る負荷伝達機構部１Ｂの摺動軸受１３ａと異なる。このため、負荷伝達機構部１Ｄの摺動軸部１４の動作が負荷伝達機構部１Ｂの摺動軸部１３と異なる。以下、負荷伝達機構部１Ｄの説明では、第２実施形態に係る負荷伝達機構部１Ｂと共通する構成については図２２ないし２４において負荷伝達機構部１Ｂの説明に用いた符号を付してその説明を省略し、第２実施形態に係る負荷伝達機構部１Ｂと異なる構成及び動作についてのみ詳細に説明する。
　なお、負荷伝達機構部１Ｄの摺動軸部１４は、負荷伝達機構部１Ｂの摺動軸部１３に相当し、形状は摺動軸部１３と同様であり、その動作が摺動軸部１３と異なる。 The structure of the sliding bearing 14a of the load transmission mechanism section 1D is different from the sliding bearing 13a of the load transmission mechanism section 1B according to the second embodiment. Therefore, the operation of the sliding shaft section 14 of the load transmission mechanism section 1D is different from that of the sliding shaft section 13 of the load transmission mechanism section 1B. Hereinafter, in the description of the load transfer mechanism section 1D, the same components as the load transfer mechanism section 1B according to the second embodiment will be described with reference numerals used in the explanation of the load transfer mechanism section 1B in FIGS. 22 to 24. will be omitted, and only the configuration and operation that are different from the load transmission mechanism section 1B according to the second embodiment will be described in detail.
The sliding shaft section 14 of the load transmission mechanism section 1D corresponds to the sliding shaft section 13 of the load transmission mechanism section 1B, has the same shape as the sliding shaft section 13, and its operation is similar to that of the sliding shaft section 13. different from.
　摺動軸部１４を軸支する摺動軸受１４ａは、クランク軸部６の軸方向に対して摺動軸部１４を斜めに挿通させる軸受穴１４ｄを有する（図２４参照）。図１２に示す様に第２実施形態に係るトレーニング器具用負荷伝達機構部１Ｂの摺動軸受１３ａは上面から下面に向かって垂直に形成された軸受穴１３ｄを備える。これに対して、負荷伝達機構部１Ｄの摺動軸受１４ａは、上面から下面に向かって斜めに傾斜する軸受穴１４ｄを備える。 The sliding bearing 14a that pivotally supports the sliding shaft 14 has a bearing hole 14d through which the sliding shaft 14 is inserted diagonally with respect to the axial direction of the crankshaft 6 (see FIG. 24). As shown in FIG. 12, the sliding bearing 13a of the training device load transmission mechanism 1B according to the second embodiment includes a bearing hole 13d formed vertically from the upper surface to the lower surface. On the other hand, the sliding bearing 14a of the load transmission mechanism section 1D includes a bearing hole 14d that is obliquely inclined from the upper surface to the lower surface.
　摺動軸受１４ａに挿通される摺動軸部１４は、クランク軸部６の軸方向に対して傾斜を持って筐体部２２に引き込まれ、または突き出される。
　第２実施形態に係る負荷伝達機構部１Ｂの摺動軸部１３とクランク軸部６とのなす角は直角であるが、負荷伝達機構部１Ｄの摺動軸部１４の中心軸とクランク軸部６の中心軸とのなす角は直角よりも大きい鈍角となるため、摺動軸部１３とクランク軸部６とを連結する連結関節部１２のクランク軸部６の回動又は水平移動に伴う変形量は負荷伝達機構部１Ｄの連結関節部１２の方が小さい。従って、摺動軸受１３ａに代えて摺動軸受１４ａを採用することで、負荷伝達機構部１Ｄの連結関節部１２の変形に伴う摩擦などの抵抗は、より小さくなるので、負荷伝達機構部１Ｄの動作は、よりスムーズに行うことができ、さらに連結関節部１２の変形量を小さくすることができるので連結関節部１２の摩耗などを抑制することができる。 The sliding shaft portion 14 inserted into the sliding bearing 14a is drawn into or protruded from the housing portion 22 at an angle with respect to the axial direction of the crankshaft portion 6.
Although the angle between the sliding shaft section 13 of the load transmission mechanism section 1B and the crankshaft section 6 according to the second embodiment is a right angle, the central axis of the sliding shaft section 14 of the load transmission mechanism section 1D and the crankshaft section Since the angle formed with the central axis of 6 is an obtuse angle larger than a right angle, the connecting joint section 12 connecting the sliding shaft section 13 and the crankshaft section 6 is deformed due to rotation or horizontal movement of the crankshaft section 6. The amount is smaller in the connecting joint part 12 of the load transmission mechanism part 1D. Therefore, by employing the sliding bearing 14a instead of the sliding bearing 13a, the resistance such as friction accompanying the deformation of the connecting joint 12 of the load transmission mechanism section 1D becomes smaller. The movement can be performed more smoothly, and the amount of deformation of the connecting joint 12 can be reduced, so that wear of the connecting joint 12 can be suppressed.
　なお、第４実施形態に係る負荷伝達機構部１Ｄの摺動軸受１４ａは、第１実施形態に係る負荷伝達機構部１Ａに適用してもよい。負荷伝達機構部１Ａに摺動軸受１４ａを適用する場合、摺動軸受１３ａに代えて摺動軸受１４ａを負荷伝達機構部１Ａに装着する。負荷伝達機構部１Ａの摺動軸部１３は、負荷伝達機構部１Ｄの摺動軸部１４に相当し、形状は摺動軸部１４と同じである。負荷伝達機構部１Ａの摺動軸部１３が摺動軸受１４ａに軸支された場合は、摺動軸部１３は摺動軸部１４と同様の動作をする。
　従って、摺動軸受１３ａに代えて摺動軸受１４ａを装着することにより、負荷伝達機構部１Ａの連結関節部１２の変形に伴う摩擦などの抵抗は小さくなるので、負荷伝達機構部１Ａの動作はよりスムーズに行うことができ、さらに連結関節部１２の変形量を小さくすることができるので連結関節部１２の摩耗などを抑制することができる。 Note that the sliding bearing 14a of the load transmission mechanism section 1D according to the fourth embodiment may be applied to the load transmission mechanism section 1A according to the first embodiment. When the sliding bearing 14a is applied to the load transmission mechanism section 1A, the sliding bearing 14a is attached to the load transmission mechanism section 1A instead of the sliding bearing 13a. The sliding shaft section 13 of the load transmission mechanism section 1A corresponds to the sliding shaft section 14 of the load transmission mechanism section 1D, and has the same shape as the sliding shaft section 14. When the sliding shaft portion 13 of the load transmission mechanism portion 1A is pivotally supported by the sliding bearing 14a, the sliding shaft portion 13 operates in the same manner as the sliding shaft portion 14.
Therefore, by installing the sliding bearing 14a in place of the sliding bearing 13a, the resistance such as friction caused by the deformation of the connecting joint 12 of the load transmission mechanism section 1A is reduced, so that the operation of the load transmission mechanism section 1A is This can be done more smoothly, and the amount of deformation of the connecting joint 12 can be reduced, so wear of the connecting joint 12 can be suppressed.
　さらに、第４実施形態に係る負荷伝達機構部１Ｄの摺動軸受１４ａは、第３実施形態に係る負荷伝達機構部１Ｃに適用してもよい。負荷伝達機構部１Ｃに摺動軸受１４ａを適用する場合、摺動軸受１３ａに代えて摺動軸受１４ａを負荷伝達機構部１Ｃに装着する。負荷伝達機構部１Ｃの摺動軸部１３は、負荷伝達機構部１Ｄの摺動軸部１４に相当し、形状は摺動軸部１４と同じである。負荷伝達機構部１Ｃの摺動軸部１３が摺動軸受１４ａに軸支された場合は、摺動軸部１３は摺動軸部１４と同様の動作をする。
　従って、摺動軸受１３ａに代えて摺動軸受１４ａを装着することにより、負荷伝達機構部１Ｃの連結関節部１２の変形に伴う摩擦などの抵抗は小さくなるので、負荷伝達機構部１Ｃの動作はよりスムーズに行うことができ、さらに連結関節部１２の変形量を小さくすることができるので連結関節部１２の摩耗などを抑制することができる。 Furthermore, the sliding bearing 14a of the load transmission mechanism section 1D according to the fourth embodiment may be applied to the load transmission mechanism section 1C according to the third embodiment. When the sliding bearing 14a is applied to the load transmission mechanism section 1C, the sliding bearing 14a is attached to the load transmission mechanism section 1C instead of the sliding bearing 13a. The sliding shaft section 13 of the load transmission mechanism section 1C corresponds to the sliding shaft section 14 of the load transmission mechanism section 1D, and has the same shape as the sliding shaft section 14. When the sliding shaft portion 13 of the load transmission mechanism portion 1C is pivotally supported by the sliding bearing 14a, the sliding shaft portion 13 operates in the same manner as the sliding shaft portion 14.
Therefore, by installing the sliding bearing 14a in place of the sliding bearing 13a, the resistance such as friction caused by the deformation of the connecting joint 12 of the load transmission mechanism section 1C is reduced, so that the operation of the load transmission mechanism section 1C is This can be done more smoothly, and the amount of deformation of the connecting joint 12 can be reduced, so wear of the connecting joint 12 can be suppressed.

With reference to FIGS. 25 to 28, the configuration and operation of a training device load transmission mechanism section 1E (hereinafter referred to as load transmission mechanism section 1E) of the fifth embodiment will be described. FIG. 25 is a diagram for explaining the configuration of the training equipment load transmission mechanism section 1E according to the fifth embodiment, and FIG. 26 is a diagram for explaining the operation of the training equipment load transmission mechanism section 1E according to the fifth embodiment. FIG. 27 is a diagram for explaining the operation of the sliding shaft section 15 of the training device load transmission mechanism section 1E according to the fifth embodiment, and FIG. It is a figure for demonstrating the sliding bearing 15a of the load transmission mechanism part 1E for instruments. FIG. 28(a) is a perspective view of the sliding bearing 15a. FIG. 28(b) is a cross-sectional view of a surface of the sliding bearing 15a cut along the cutting surface 15e shown in FIG. 28(a), viewed from the direction of arrow A.
The load transmission mechanism section 1E is used while being connected to the first training device 100 and the second training device 201.
　負荷伝達機構部１Ｅの摺動軸受１５ａの構成が第２実施形態に係る負荷伝達機構部１Ｂの摺動軸受１３ａと異なる。このため、負荷伝達機構部１Ｅの摺動軸部１５の動作が負荷伝達機構部１Ｂの摺動軸部１３と異なる。以下、負荷伝達機構部１Ｅの説明では、第２実施形態に係る負荷伝達機構部１Ｂと共通する構成については図２５ないし２８において負荷伝達機構部１Ｂの説明に用いた符号を付してその説明を省略し、第２実施形態に係る負荷伝達機構部１Ｂと異なる構成及び動作についてのみ詳細に説明する。
　なお、負荷伝達機構部１Ｅの摺動軸部１５は、負荷伝達機構部１Ｂの摺動軸部１３に相当し、形状は摺動軸部１３と同じであり、その動作が摺動軸部１３と異なる。 The structure of the sliding bearing 15a of the load transmission mechanism section 1E is different from the sliding bearing 13a of the load transmission mechanism section 1B according to the second embodiment. Therefore, the operation of the sliding shaft section 15 of the load transmission mechanism section 1E is different from that of the sliding shaft section 13 of the load transmission mechanism section 1B. Hereinafter, in the description of the load transfer mechanism section 1E, the same components as the load transfer mechanism section 1B according to the second embodiment will be described with reference numerals used in the explanation of the load transfer mechanism section 1B in FIGS. 25 to 28. will be omitted, and only the configuration and operation that are different from the load transmission mechanism section 1B according to the second embodiment will be described in detail.
The sliding shaft section 15 of the load transmission mechanism section 1E corresponds to the sliding shaft section 13 of the load transmission mechanism section 1B, has the same shape as the sliding shaft section 13, and operates in the same manner as the sliding shaft section 13. different from.
　トレーニング器具用負荷伝達機構部１Ｅ（以下、負荷伝達機構部１Ｅという）は、摺動軸部１５を軸支する摺動軸受１５ａは、クランク軸部６の軸方向に対して直交して挿通する第１軸受穴１５ｊと、第１軸受穴１５ｊに交差し、かつ、クランク軸部６の軸方向に対して斜めに挿通する第２軸受穴１５ｋを有し、摺動軸部１５は、クランク軸部６の軸方向の移動に伴い第１軸受穴１５ｊと第２軸受穴１５ｋとの間を移動する。 In the training device load transmission mechanism section 1E (hereinafter referred to as load transmission mechanism section 1E), a sliding bearing 15a that pivotally supports the sliding shaft section 15 is inserted orthogonally to the axial direction of the crankshaft section 6. The sliding shaft portion 15 has a first bearing hole 15j and a second bearing hole 15k that intersects the first bearing hole 15j and is inserted obliquely to the axial direction of the crankshaft portion 6. As the portion 6 moves in the axial direction, it moves between the first bearing hole 15j and the second bearing hole 15k.
　摺動軸受１５ａの軸受穴１５ｄは第１軸受穴１５ｊと第２軸受穴１５ｋを備える。図２８（ｂ）に示す様に、第１軸受穴１５ｊは上部筒側面部１５ｆと下部円筒側面部１５ｇとによって形成され、第２軸受穴１５ｋは上部斜円錐側面部１５ｈと下部斜円錐側面部１５ｉとによって形成される。 The bearing hole 15d of the sliding bearing 15a includes a first bearing hole 15j and a second bearing hole 15k. As shown in FIG. 28(b), the first bearing hole 15j is formed by an upper cylindrical side surface 15f and a lower cylindrical side surface 15g, and the second bearing hole 15k is formed by an upper oblique conical side surface 15h and a lower oblique conical side surface. 15i.
　図２５ないし２７に示す様に、第１軸受穴１５ｊと第２軸受穴１５ｋとは交差するため、摺動軸部１５は、第１軸受穴１５ｊに支持された状態と第２軸受穴１５ｋに支持された状態との間を遷移することができる。図２５及び図２７（ａ）は摺動軸部１５が第１軸受穴１５ｊに支持された状態を示し、図２６及び図２７（ｂ）は摺動軸部１５が第２軸受穴１５ｋに支持された状態を示す。 As shown in FIGS. 25 to 27, since the first bearing hole 15j and the second bearing hole 15k intersect, the sliding shaft portion 15 can be supported in the first bearing hole 15j and in the second bearing hole 15k. It is possible to transition between supported states. 25 and 27(a) show a state in which the sliding shaft portion 15 is supported in the first bearing hole 15j, and FIG. 26 and FIG. 27(b) show a state in which the sliding shaft portion 15 is supported in the second bearing hole 15k. Indicates the state in which the
　摺動軸部１５は、鉛直状態では第１軸受穴１５ｊに支持され、最大限傾斜した状態では第２軸受穴１５ｋに支持される。摺動軸部１５は、鉛直状態と最大限傾斜した状態との間の状態では、くびれ部１５ｍに支持される。くびれ部１５ｍは、図２８（ｂ）に示す様に、上部筒側面部１５ｆと下部斜円錐側面部１５ｉとの境界、及び、上部斜円錐側面部１５ｈと下部円筒側面部１５ｇとの境界に形成される。 The sliding shaft portion 15 is supported by the first bearing hole 15j in the vertical state, and supported by the second bearing hole 15k in the maximum tilted state. The sliding shaft portion 15 is supported by the constriction portion 15m in a state between the vertical state and the maximum tilted state. As shown in FIG. 28(b), the constricted portion 15m is formed at the boundary between the upper cylindrical side surface 15f and the lower oblique conical side surface 15i, and at the boundary between the upper oblique conical side surface 15h and the lower cylindrical side surface 15g. be done.
　負荷伝達機構部１Ｅの握持部１１にユーザの力の入力が無い状態、即ち、負荷伝達機構部１Ｅの初期状態において、摺動軸部１５は筐体部２２の外部に突出する部分が最も長い。この初期状態のとき、握持部１１は鉛直状態となり第１軸受穴１５ｊに支持される。負荷伝達機構部１Ｅの初期状態において、主動軸部４は図２５の紙面上最も右側に位置する。 In a state in which no user force is input to the grip portion 11 of the load transmission mechanism portion 1E, that is, in an initial state of the load transmission mechanism portion 1E, the portion of the sliding shaft portion 15 that protrudes to the outside of the casing portion 22 is the most long. In this initial state, the grip portion 11 is in a vertical state and supported by the first bearing hole 15j. In the initial state of the load transmission mechanism section 1E, the main drive shaft section 4 is located on the rightmost side on the paper surface of FIG.
　そして、ユーザにより握持部１１への水平移動若しくは回動の入力が行われることによって、摺動軸部１５は筐体部２２内部に徐々に引き込まれるとともに傾斜角が大きくなる。この状態において、主動軸部４は、第１軸受穴１５ｊによる支持からくびれ部１５ｍに支持される状態に遷移する。 Then, when the user inputs horizontal movement or rotation to the grip portion 11, the sliding shaft portion 15 is gradually drawn into the housing portion 22 and the inclination angle increases. In this state, the main drive shaft portion 4 transitions from being supported by the first bearing hole 15j to being supported by the constricted portion 15m.
　さらに、ユーザにより握持部１１への水平移動及び回動の入力が行われることによって、最大限傾斜した状態となり、くびれ部１５ｍによる摺動軸部１５の支持から第２軸受穴１５ｋによる支持に遷移する。 Furthermore, when the user inputs horizontal movement and rotation to the gripping part 11, the state is tilted to the maximum extent, and the sliding shaft part 15 is changed from being supported by the constricted part 15m to being supported by the second bearing hole 15k. Transition.
　摺動軸受１５ａの側平面１５ｌは平な面である。側平面１５ｌは摺動軸受１５ａの位置合わせに用いられる。摺動軸受１５ａの位置決めの基準となる平面に側平面１５ｌを当接させることで、摺動軸受１５ａの位置及び角度を規定する。 The side plane 15l of the sliding bearing 15a is a flat surface. The side plane 15l is used for positioning the sliding bearing 15a. By bringing the side plane 15l into contact with a plane that serves as a reference for positioning the sliding bearing 15a, the position and angle of the sliding bearing 15a are defined.
　負荷伝達機構部１Ｅは、摺動軸受１５ａを用いることによって、摺動軸部１５が傾斜するので連結関節部１２の屈曲する大きさを抑制することができる。これにより、従って、摺動軸受１３ａに代えて摺動軸受１５ａを採用することで、負荷伝達機構部１Ｅの連結関節部１２の変形に伴う摩擦などの抵抗は、より小さくなるので、負荷伝達機構部１Ｅの動作は、よりスムーズに行うことができ、さらに連結関節部１２の変形量を小さくすることができるので連結関節部１２の摩耗などを抑制することができる。 In the load transmission mechanism section 1E, by using the sliding bearing 15a, the sliding shaft section 15 is inclined, so that the degree of bending of the connecting joint section 12 can be suppressed. Therefore, by employing the sliding bearing 15a instead of the sliding bearing 13a, resistance such as friction accompanying deformation of the connecting joint section 12 of the load transmission mechanism section 1E becomes smaller, so that the load transmission mechanism The operation of the portion 1E can be performed more smoothly, and the amount of deformation of the connecting joint portion 12 can be reduced, so that wear and the like of the connecting joint portion 12 can be suppressed.
　なお、第５実施形態に係る負荷伝達機構部１Ｅの摺動軸受１５ａは、第１実施形態に係る負荷伝達機構部１Ａに適用してもよい。負荷伝達機構部１Ａに摺動軸受１５ａを適用する場合、摺動軸受１３ａに代えて摺動軸受１５ａを負荷伝達機構部１Ａに装着する。負荷伝達機構部１Ａの摺動軸部１３は、負荷伝達機構部１Ｅの摺動軸部１５に相当し、形状は摺動軸部１５と同じである。負荷伝達機構部１Ａの摺動軸部１３が摺動軸受１５ａに軸支された場合は、摺動軸部１３は摺動軸部１５と同様の動作をする。
　従って、摺動軸受１３ａに代えて摺動軸受１５ａを装着することにより、負荷伝達機構部１Ａの連結関節部１２の変形に伴う摩擦などの抵抗は小さくなるので、負荷伝達機構部１Ａの動作はよりスムーズに行うことができ、さらに連結関節部１２の変形量を小さくすることができるので連結関節部１２の摩耗などを抑制することができる。 Note that the sliding bearing 15a of the load transmission mechanism section 1E according to the fifth embodiment may be applied to the load transmission mechanism section 1A according to the first embodiment. When applying the sliding bearing 15a to the load transmission mechanism section 1A, the sliding bearing 15a is attached to the load transmission mechanism section 1A instead of the sliding bearing 13a. The sliding shaft section 13 of the load transmission mechanism section 1A corresponds to the sliding shaft section 15 of the load transmission mechanism section 1E, and has the same shape as the sliding shaft section 15. When the sliding shaft portion 13 of the load transmission mechanism portion 1A is pivotally supported by the sliding bearing 15a, the sliding shaft portion 13 operates in the same manner as the sliding shaft portion 15.
Therefore, by installing the sliding bearing 15a in place of the sliding bearing 13a, the resistance such as friction caused by the deformation of the connecting joint 12 of the load transmission mechanism section 1A is reduced, so that the operation of the load transmission mechanism section 1A is This can be done more smoothly, and the amount of deformation of the connecting joint 12 can be reduced, so wear of the connecting joint 12 can be suppressed.
　さらに、第５実施形態に係る負荷伝達機構部１Ｅの摺動軸受１５ａは、第３実施形態に係る負荷伝達機構部１Ｃに適用してもよい。負荷伝達機構部１Ｃに摺動軸受１５ａを適用する場合、摺動軸受１３ａに代えて摺動軸受１５ａを負荷伝達機構部１Ｃに装着する。負荷伝達機構部１Ｃの摺動軸部１３は、負荷伝達機構部１Ｅの摺動軸部１５に相当し、形状は摺動軸部１５と同じである。負荷伝達機構部１Ｃの摺動軸部１３が摺動軸受１５ａに軸支された場合は、摺動軸部１３は摺動軸部１５と同様の動作をする。
　従って、摺動軸受１３ａに代えて摺動軸受１５ａを装着することにより、負荷伝達機構部１Ｃの連結関節部１２の変形に伴う摩擦などの抵抗は小さくなるので、負荷伝達機構部１Ｃの動作はよりスムーズに行うことができ、さらに連結関節部１２の変形量を小さくすることができるので連結関節部１２の摩耗などを抑制することができる。 Furthermore, the sliding bearing 15a of the load transmission mechanism section 1E according to the fifth embodiment may be applied to the load transmission mechanism section 1C according to the third embodiment. When applying the sliding bearing 15a to the load transmission mechanism section 1C, the sliding bearing 15a is attached to the load transmission mechanism section 1C instead of the sliding bearing 13a. The sliding shaft section 13 of the load transmission mechanism section 1C corresponds to the sliding shaft section 15 of the load transmission mechanism section 1E, and has the same shape as the sliding shaft section 15. When the sliding shaft portion 13 of the load transmission mechanism portion 1C is pivotally supported by the sliding bearing 15a, the sliding shaft portion 13 operates in the same manner as the sliding shaft portion 15.
Therefore, by installing the sliding bearing 15a in place of the sliding bearing 13a, the resistance such as friction caused by the deformation of the connecting joint 12 of the load transmission mechanism section 1C is reduced, so that the operation of the load transmission mechanism section 1C is This can be done more smoothly, and the amount of deformation of the connecting joint 12 can be reduced, so wear of the connecting joint 12 can be suppressed.
