It is preferable to interpose (not shown).
[0027] 揺動駆動部材 50は、駆動部 5の動力により左右往復することで、規制部材 32と共 に揺動部材 40を左右方向に揺動させるものである。この揺動駆動部材 50は、スライ ド体 51と、第 1回転体 52、偏心軸 53とを有している。  The swing drive member 50 swings the swing member 40 in the left-right direction together with the regulating member 32 by reciprocating left and right by the power of the drive unit 5. The swing drive member 50 includes a slide body 51, a first rotating body 52, and an eccentric shaft 53.
スライド体 51は左右方向移動自在に支持されている。詳しくは、ベース 10の後側で 且つベース 10の左右両側に一対の支持体 54L, 54Rが設けられている。支持体 54 L, 54Rには、一対の固定軸 55F, 55Rが取り付けられている。  The slide body 51 is supported so as to be movable in the left-right direction. Specifically, a pair of supports 54L and 54R are provided on the rear side of the base 10 and on both the left and right sides of the base 10. A pair of fixed shafts 55F and 55R are attached to the supports 54L and 54R.

One fixed shaft 55F is attached to the front side of the supports 54L and 54R, and the other fixed shaft 55R is attached to the rear side of the supports 54L and 54R. It has been. The slide body 51 is attached to the front and rear fixed shafts 55F and 55R so as to be movable in the left and right directions.
[0028] スライド体 51には、前後に延びる第 3摺動溝 56が設けられている。また、スライド体  The slide body 51 is provided with a third sliding groove 56 extending in the front-rear direction. Also slide body
51には第 3摺動溝 56を上方から覆うように、プレート 57が取り付けられている。この プレート 57には、当該プレート 57から上方に立ち上がる係止棒 58が設けられ、係止 棒 58の上端は、揺動部材 40の後側に設けられた係合部 59に係合されている。この 係合部 59は前後方向に延びる長孔とされている。 A plate 57 is attached to 51 so as to cover the third sliding groove 56 from above. The plate 57 is provided with a locking rod 58 that rises upward from the plate 57. The upper end of the bar 58 is engaged with an engagement portion 59 provided on the rear side of the swing member 40. The engaging portion 59 is a long hole extending in the front-rear direction.
第 1回転体 52は、駆動部 5の動力により上下方向の軸回りに回転し、且つ、スライド 体 51の下側に配置されたもので、前記第 3ギア 27と同じものである。  The first rotating body 52 is rotated about the vertical axis by the power of the drive unit 5 and is disposed below the slide body 51, and is the same as the third gear 27.
[0029] 偏心軸 53は、第 3ギア 27の軸芯である第 3回転軸 28に偏心した状態で当該第 3ギ ァ 27に取り付けられている。詳しくは、偏心軸 53は、第 3ギア 27の上面から上方へ立 ち上げられており、偏心軸 53の上端はスライド体 51の第 3摺動溝 56に摺動自在に 嵌められている。 The eccentric shaft 53 is attached to the third gear 27 in a state of being eccentric with respect to the third rotating shaft 28 that is the axis of the third gear 27. Specifically, the eccentric shaft 53 is raised upward from the upper surface of the third gear 27, and the upper end of the eccentric shaft 53 is slidably fitted in the third sliding groove 56 of the slide body 51.
図 2,図 3に示すように、第 3ギア 27の軸芯に対する偏心軸 53と係止棒 58との偏心 度合いを見たとき、係止棒 58は偏心軸 53よりも偏心した状態にある。  As shown in FIGS. 2 and 3, when the degree of eccentricity between the eccentric shaft 53 and the locking rod 58 with respect to the axis of the third gear 27 is seen, the locking rod 58 is more eccentric than the eccentric shaft 53. .
揺動部 4によれば、第 3回転軸 28 (第 1回転体 52の縦軸）を回転させると、偏心軸 5 3は第 3回転軸 28回りに回転運動をする。このとき、偏心軸 53の上端はスライド体 51 の第 3摺動溝 56を前後に摺動するので、偏心軸 53によってスライド体 51が左右に往 復移動する。スライド体 51が左右に往復移動することで、プレート 57及び係止棒 58 が左右に移動することとなる。  According to the oscillating portion 4, when the third rotating shaft 28 (vertical axis of the first rotating body 52) is rotated, the eccentric shaft 53 rotates about the third rotating shaft 28. At this time, since the upper end of the eccentric shaft 53 slides back and forth in the third sliding groove 56 of the slide body 51, the slide body 51 moves back and forth by the eccentric shaft 53. As the slide body 51 reciprocates left and right, the plate 57 and the locking rod 58 move left and right.
[0030] 係止棒 58が左右に移動することで、係止棒 58に係合している揺動部材 40は第 2 回転軸 48 (円柱 31の軸芯）を中心として左右方向に揺動する。揺動部材 40の左右 方向の揺動により規制部材 32が左右に揺動することとなり、規制部材 32に連結して いるリング体 35が揺動して、その結果、座部 2が左右方向に揺動することとなる。 次に、屈伸運動装置 1の作動態様について図 8，図 9を用いて説明する。 なお、作動態様の説明において、駆動開始直後は、座部 2が最も下がっている状 態であって、座部 2の前部における左右方向中央 C1が装置の左右方向中心 C2と一 致している状態とする。 [0030] As the locking rod 58 moves to the left and right, the swinging member 40 engaged with the locking rod 58 swings in the left-right direction around the second rotating shaft 48 (the axis of the cylinder 31). To do. As the swing member 40 swings in the left-right direction, the restricting member 32 swings left and right, and the ring body 35 connected to the restricting member 32 swings. As a result, the seat portion 2 moves in the left-right direction. It will swing. Next, the operation mode of the bending and stretching apparatus 1 will be described with reference to FIGS. In the description of the operation mode, immediately after the start of driving, the seat 2 is in the lowest position, and the center C1 in the left-right direction at the front of the seat 2 matches the center C2 in the left-right direction of the device. State.
[0031] 屈伸運動装置 1を使用するには、使用者 Uは座部 2に座った状態で足を床に付き、 この状態で駆動部 5を駆動することとなる。  [0031] To use the bending and stretching exercise device 1, the user U sits on the seat 2 and puts his / her foot on the floor, and drives the drive unit 5 in this state.
駆動部 5を駆動すると、まず、駆動モータ 20の駆動軸における回転動力がギアボッ タス 21を経て第 1ギア 25に伝達される。第 1ギア 25に伝達された動力は、第 2ギア 26 を経て第 2回転軸 48に伝達されると共に、第 3ギア 27を経て偏心軸 53に伝達される 。第 2ギア 26と第 3ギア 27との回転比は 2対 1なので、第 2回転軸 48は第 3回転軸 28 よりも 2倍の速さで回転する。第 2回転軸 48の回転によって円柱 31は回転し、第 1摺 動溝 33に嵌り込んだ第 1摺動体 37が当該第 1摺動体 37に沿って移動し、図 8 (a)か ら図 8 (b)に示すように、リング体 35が上昇を開始する。 When the drive unit 5 is driven, first, rotational power in the drive shaft of the drive motor 20 is transmitted to the first gear 25 via the gear button 21. The power transmitted to the first gear 25 is transmitted to the second rotating shaft 48 via the second gear 26 and also transmitted to the eccentric shaft 53 via the third gear 27. . Since the rotation ratio between the second gear 26 and the third gear 27 is 2 to 1, the second rotating shaft 48 rotates at twice the speed of the third rotating shaft 28. The cylinder 31 is rotated by the rotation of the second rotating shaft 48, and the first sliding body 37 fitted in the first sliding groove 33 moves along the first sliding body 37, and FIG. 8 (a) to FIG. 8 As shown in (b), the ring body 35 starts to rise.
[0032] 図 8 (a) ,図 8 (b)に示すように、リング体 35が上昇を開始すると同時に、偏心軸 53 による偏心運動によってスライド体 51が左右方向一方 (右側）に移動する。スライド体 51の右側への移動により、揺動部材 40の前側は左側に移動するので、座部 2の中 央 C1は装置の中心 C2より左側に移動することとなる。 [0032] As shown in FIGS. 8 (a) and 8 (b), the ring body 35 starts to rise, and at the same time, the slide body 51 moves to one side (right side) in the left-right direction by the eccentric motion by the eccentric shaft 53. As the slide body 51 moves to the right side, the front side of the swing member 40 moves to the left side, so that the center C1 of the seat 2 moves to the left side from the center C2 of the apparatus.
図 8 (b)，図 8 (c)に示すように、座部 2は上昇しながら左側に徐々に移動して!/、く。 そして、リング体 35が円柱 31の上端に達すると、揺動部材 40の前側も装置の中心 C 2から最も左側に移動した状態 (スライド体 51が右側に最も移動した状態）となるので 、座部 2は、最も上昇した位置で且つ座部 2の中央 C1は装置の中心 C2より左側に最 も離れた位置となる。  As shown in Fig. 8 (b) and Fig. 8 (c), seat 2 gradually moves to the left as it rises! When the ring body 35 reaches the upper end of the cylinder 31, the front side of the swing member 40 is also moved to the leftmost side from the center C2 of the device (the slide body 51 is moved most to the right side). Part 2 is the highest position, and the center C1 of the seat part 2 is farthest to the left of the center C2 of the device.
[0033] 言い換えれば、リング体 35が円柱 31の上端に達したときは、座部 2の前側は左側 へ最も大きく移動 (揺動）した状態となる。  In other words, when the ring body 35 reaches the upper end of the cylinder 31, the front side of the seat portion 2 is moved (swinged) to the left most.
リング体 35が円柱 31の上端側に達した後は、リング体 35は徐々に下降すると共に After the ring body 35 reaches the upper end side of the cylinder 31, the ring body 35 gradually descends and
、揺動部材 40の前側も装置の中心 C2側へと移動 (スライド体 51が右側に最も移動し た状態から左側へ移動）することこなり、座部 2は徐々に下降すると共に、座部 2の前 側は徐々に装置の中心 C2に向けて移動する。 The front side of the swinging member 40 also moves to the center C2 side of the device (the slide body 51 moves from the most moved right side to the left side), and the seat 2 gradually descends and the seat The front side of 2 gradually moves toward the center C2.
図 8 (a)に示すように、リング体 35が再び円柱 31の下端側に達した後は、座部 2は 最も下がっていると共に、座部 2の中央 C1は装置の中心 C2と同じ位置となり、駆動 開始直後に位置に戻る。  As shown in Fig. 8 (a), after the ring body 35 reaches the lower end side of the cylinder 31 again, the seat 2 is lowered most and the center C1 of the seat 2 is the same position as the center C2 of the device. And return to the position immediately after the start of driving.
[0034] このように、座部 2は、最も下がった状態から徐々に上昇すると共に、この上昇動作 に合わせて (連動して）装置の中心 C2から左右方向一方側へと移動する。そして、座 部 2は、最も上昇した状態から徐々に下降すると共に、下降動作に合わせて (連動し て)装置の中心へと戻る。 [0034] Thus, the seat 2 gradually rises from the lowest position, and moves from the center C2 of the apparatus to one side in the left-right direction in conjunction with (in conjunction with) this raising operation. Then, the seat 2 gradually descends from the most elevated state and returns to the center of the apparatus in conjunction with (in conjunction with) the descending motion.
そして、図 9 (b)，図 9 (c)に示すように、座部 2が下降して、最も下がって!/、る位置に 達した後は、座部 2は再び上昇すると共に、座部 2の中央 C1は装置の中心 C2から 左右方向他方 (右側）へと移動する。 Then, as shown in FIGS. 9 (b) and 9 (c), after the seat 2 is lowered and reaches the lowest position! /, The seat 2 rises again and the seat 2 Center C1 of part 2 from the center C2 of the device Move to the other side (right side).
[0035] リング体 35が円柱 31の上端に達すると、揺動部材 40の前側も装置の中心 C2から 最も右側に移動した状態 (スライド体 51が左側に最も移動した状態）となるので、座 部 2は、最も上昇した位置で且つ座部 2の中央 C1は装置の中心 C2より左側に最も 離れた位置となる。即ち、リング体 35が円柱 31の上端に達したときは、座部 2の前側 は左側へ最も大きく揺動した状態となる。 [0035] When the ring body 35 reaches the upper end of the cylinder 31, the front side of the swinging member 40 is also moved to the rightmost side from the center C2 of the device (the slide body 51 is moved most to the left side). Part 2 is the highest position, and the center C1 of the seat part 2 is the farthest left side from the center C2 of the device. That is, when the ring body 35 reaches the upper end of the cylinder 31, the front side of the seat portion 2 is most swayed to the left side.
リング体 35が円柱 31の上端側に達した後は、リング体 35は徐々に下降すると共に 、揺動部材 40の前側も装置の中心 C2側へと移動 (スライド体 51が左側に最も移動し た状態から右側へ移動）するため、座部 2は徐々に下降すると共に、座部 2の前側は 徐々に装置の中心 C2に移動する。  After the ring body 35 reaches the upper end side of the cylinder 31, the ring body 35 gradually descends, and the front side of the swing member 40 also moves to the center C2 side of the device (the slide body 51 moves most to the left side). The seat part 2 gradually descends and the front side of the seat part 2 gradually moves to the center C2 of the device.
[0036] このように、座部 2は、上昇した位置から最も下がった状態に戻ると、再び、徐々に 上昇すると共に、この上昇動作に合わせて (連動して)装置の中心 C2から左右方向 他方側へと移動する。そして、座部 2は、最も上昇した状態から徐々に下降すると共 に、下降動作に合わせて (連動して)装置の中心 C2へと戻るようになって!/、る。 [0036] In this way, when the seat 2 returns to the lowest position from the raised position, the seat 2 gradually rises again, and in accordance with this ascent action (in conjunction) from the center C2 of the device in the left-right direction Move to the other side. Then, the seat 2 gradually descends from the most elevated state, and returns to the center C2 of the device in conjunction with the descending motion (in conjunction)! /.
屈伸運動装置 1によれば、座部 2は昇降すると共に、この昇降動作に連動して左右 方向にも揺動するため、下肢にやや負担をかけた状態で屈伸運動 (スクワット運動）と 腰等にひねり運動をすることができる。  According to the bending and stretching exercise device 1, the seat 2 moves up and down and swings in the left and right direction in conjunction with the lifting and lowering operation. Therefore, the bending and stretching exercise (squat exercise) and the waist are performed with a slight load on the lower limbs. You can exercise to twist.
また、屈伸運動装置 1は、座部 2に座った状態で屈伸運動をする構成であるため、 狭レ、スペースでも屈伸運動を行うことができる。  In addition, since the bending and stretching exercise device 1 is configured to perform bending and stretching while sitting on the seat 2, it can perform bending and stretching even in a narrow space.
