The part goes into the inside, so that it does not hurt the user's knee.

  In the present invention, it is possible to easily put a foot on the heel, and at the same time, when the heel is subjected to a swinging motion, the heel comes to a position that does not place a burden on the user's knee, You can maintain a good posture and never hurt your knees.

  Hereinafter, the present invention will be described based on the embodiments shown in the accompanying drawings. The swing type exercise device shown in FIGS. 2 and 3 swings the seat 2 on which the user sits to the seat 2 by swinging back and forth and right and left. The seat 2 allows the sitting user to perform an exercise for balance training. The seat 2 has a shape imitating the back of a horse and a saddle and the upper surface is a seating surface, and the seat 2 swings in the upper portion. It consists of a main body 1 that houses a drive unit 3 for driving, and a reins 6 are arranged on the front end side of the seat 2 and are semicircular and both ends are pivotally connected to the seat 2 back and forth. At the same time, an operation panel 8 is provided, and hooks 7 and 7 are suspended from both front sides of the seat 2, respectively.

  As shown in FIG. 5, the main body 1 includes a base frame 11 having grounding legs 15 at four corners, a support column 12 that rises obliquely rearward from a substantially central portion of the base frame 11, and a support column 12 with respect to the support column 12. A support frame 13 slidably mounted in the longitudinal direction of the base frame 11, and an electric slide unit 14 that electrically slides the support frame 13. The outer surface is covered with a cover 17 covering the outer periphery, a main cover 18 covering the outer periphery of the support frame 13, and the like.

  On the other hand, as shown in FIG. 6, the seat 2 is attached to the seat frame 20, the seat surface 21 attached to the upper surface of the seat frame 20, the cover 22 connected to the lower side of the seat frame 20, and the left and right sides of the seat frame 20. A protective cover 23, a panel cover 24 covering the periphery of the operation panel 8, and the like.

  The heel 7 includes an attachment piece 71 fixed to the heel attachment portion 200 on the side surface of the seat frame 20, a connection piece 72 suspended from the attachment piece 71, and a footrest piece 70 suspended from the connection piece 72. Thus, the protective cover 23 covers the outer side of the connecting shaft portion of the connecting piece 72 to the mounting piece 71 and prevents the knee portion of the user sitting on the seat 2 from hitting the connecting shaft portion.

  Next, the drive unit 3 will be described. As shown in FIGS. 7 to 10, the drive unit 3 includes a motor 31 and a gear group 34 that transmits the rotation of the motor 31 to the two output shafts 32 and 33 in a box-shaped movable frame 30. , And a movable plate 40 positioned above the movable frame 30 is connected to the movable frame 30 by two types of link plates 41, 42. The movable frame 30 includes bearing portions 300, 300 is attached to the main body 1 by being connected to the support frame 13 in the main body 1 by means of shafts 130 and 130 shown in FIG.

  Here, the link plate 41 connected to the rear end side of the movable plate 40 is connected to the rear side surface of the movable frame 30 by the shaft 301, whereas the link plate 42 is connected to the inside of the movable frame 30. The link plate 42 is supported on the front end side of the movable plate 40 on the front end side of the movable plate 40, and the link plate 42 is supported on the front end side of the movable plate 40. It is connected through.

  The output shaft 32 of the two output shafts 32 and 33 that are rotationally driven has an eccentric portion located on the outer surface side of the movable frame 30, and this eccentric portion is connected to the support frame 13 by a link 35. Has been.

  The other output shaft 33 has two eccentric portions 33a and 33b located on the outer surface side of the movable frame 30, and the eccentric portion 33a having a small eccentric amount is connected to the link plate 42 and has an eccentric portion having a large eccentric amount. 33 b is connected to a connecting link 36 having one end connected to the link plate 41.

  Of the two output shafts 32, 33, the rotation of the eccentric portion of the output shaft 32 connected to the support frame 13 by the link 35 causes the movable frame 30 to rotate on the shaft 130 (the longitudinal axis A tilted back and forth in FIG. 9). ).

Further, the eccentric rotation of the eccentric portion 33a of the other output shaft 33 swings the front end side of the movable plate 40 back and forth and up and down via the link plate 42 and the telescopic actuator 45, and the eccentric rotation of the eccentric portion 33b is connected to the connecting link 36. The rear end side of the movable plate 40 is mainly swung back and forth via the link plate 41. As shown in FIG. 9, the trajectory of back and forth swinging of the connecting shaft 40a between the link plate 41 and the movable plate 40 is represented by T1. When the trajectory of back and forth of the connecting shaft 40b between the telescopic actuator 45 and the movable plate 40 is T2, the strokes of both are the same, but the vertical component is set to be different between the trajectories T1 and T2. together are, in order to lower the position of the axis 303 of rotation plate 39 becomes the rotation fulcrum of the link plate 42, the locus T2 is a forward Has become shall take root shifted up or down in the road.

  Here, the seat 2 is configured such that the seat frame 20 is fixed on the movable plate 40 which is driven to swing back and forth and right and left as the output shafts 32 and 33 rotate. Swing back and forth and right and left together with the plate 40. Further, since it is set so that the front / rear swing is performed two cycles during one cycle of the left / right swing, the center of the seat surface 21 of the seat 2 that is the lowest in the front / rear direction is the center in the left / right direction. The point 21a draws a figure 8 in a plan view as shown in FIG.

  Also, due to the difference between the trajectories T1 and T2, the center point of the seat 2 is drawn as shown in FIG. Since the trajectory T1 on the rear end side 2 is a longitudinal movement with a small vertical motion component, and the trajectory T2 on the front end side of the seat 2 is a longitudinal motion with a large vertical motion component, the vertical movement of the seat 2 is backward. The front end is moved up and down with the side as a fulcrum. When sitting on the seat 2, the user who positions the center of gravity substantially coincides with the center point of the seat 2 moves the seat 2 up and down with the rear end side of the seat 2 positioned behind the seat 2 as a fulcrum. You will feel more accurately.

  FIG. 4 shows a plot of the movement of the center point of the sheet 2 at predetermined time intervals. For this reason, when the point interval is large, the speed is high, and from a small interval to a large interval in a short time. The change shows that the acceleration is large. That is, in the case shown in FIG. 4, the acceleration when moving forward is larger than the acceleration when moving backward. This means that if you sit on the seat 2 and receive the movement of the seat 2, you will feel that you are moving forward, and for this you can get the feeling of actually riding. .

  Further, since the left and right swings are not about the axis of the horizontal axis substantially parallel to the movable plate 40 and the seating surface 21, but the front side is about the axis of the front and rear axis A that is lower than the rear side. Although the front and rear sides swing left and right within the same angular range, the distance from the front and rear axis A is longer on the front side than on the rear side. It is larger than the left / right movement stroke on the rear end side. For this reason, the movement in the shape of figure 8 in a plan view by combining the rocking in the front-rear direction (pitch) and the rocking in the left-right direction (roll) is as shown in FIG. The lateral movement width of the seat 2 is larger than the lateral movement width on the rear side, and the forward oblique movement includes a yaw component in which the front end side of the seat 2 moves while being twisted obliquely forward.

  Therefore, when the user sits on the seat 2 and receives the above movement of the seat 2, the user cannot keep balance unless he / she copes with the yaw movement in addition to the pitch and roll. It is more effective in terms of balance training.

  The expansion / contraction actuator 45 in the drive unit 3 is provided to change the front / rear inclination angle of the seat 2, and the expansion / contraction actuator 45 expands / contracts by an operation on the operation panel 8 to be described later. In addition, the vertical movement component may be increased or decreased by performing expansion / contraction in conjunction with the above-described back-and-forth movement.

  Further, if the front / rear inclination angle of the seat 2 is changed, the load applied to each muscle (abdominal muscle, back muscle, thigh front muscle, thigh rear muscle) of the user when the seat 2 is swung is also changed. In order to allow the user to clearly understand this change, here, the load on each muscle can be displayed on the operation panel 8 as described later. The load condition is determined on the basis of data on how the myoelectric potential of each muscle changes depending on the difference in the front and rear inclination angle of the seat 2.

  By the way, when the user sits on the seat 2 and receives the above movement of the seat 2, the user can swing more safely by placing his toes on the heel 7 and holding the reins 6. The hook 7 can be adjusted to the height of the user's physique and preference because the connecting point of the leg piece 70 to the connecting piece 72 can be adjusted up and down.鐙 7 can be set.

  Further, the connecting piece 72 is formed of an elastic material and can be bent to the left and right, and the footrest piece 70 connected to the outer surface of the connecting piece 72 is higher toward the outer side as shown by the right side collar 7 in FIG. It is easy to put a foot on the footrest piece 70 by having the bottom piece having the slope α, which is offset to the outside. Then, when the foot is hung on the footrest piece 70 of the heel 7, as shown in the heel 7 on the left side in FIG. The bottom piece is in a horizontal state. When the toes are placed on the heel 7, a good posture can be maintained regardless of excessive force on the ankles and knees.

  FIG. 11 shows the operation panel 8 arranged at the front end of the seat 2. In the figure, 80 is a power switch, 81 is a height adjustment switch for adjusting the height of the seat 2 by operating the electric slide unit 14, and 82 is for adjusting the inclination angle of the seat 2 by operating the telescopic actuator 45. 83 is a speed adjustment switch for adjusting the swinging speed by changing the rotational speed of the motor 31 of the driving unit 3, 84 is an up / down switch for inputting a weight value of the user, and 85 is a swinging switch. An operation mode selection switch for suppressing the movement operation to be suitable for beginners, 86 an operation mode switching switch for switching the exercise intensity by the swinging operation, 87 an exercise object changeover switch for switching the exercise object, and 88 a liquid crystal panel It is a display composed of When the movement object changeover switch 87 is operated, the front / rear inclination angle of the seat 2 is switched to a state suitable for each by the telescopic actuator 45.

  The display 88 displays the inclination state of the sheet 2, the display of the speed adjustment state, the display of the operation time, the display of the exercise intensity, the display of the calculated amount of exercise (calorie consumption), and the sheet 2 by the expansion and contraction of the expansion / contraction actuator 45. By displaying the posture change of the front / rear inclination of the human body, what value load is applied to which muscle of the abdominal muscles / back muscles / thigh front / thigh rear of the human body is displayed. The amount of exercise is calculated based on the output of the acceleration sensor provided on the seat 2 and the input weight value.
