Description

  The present invention relates to a swing type exercise device that swings a seat on which a user is seated and applies an exercise load imitating riding to the user.

  Rocking-type exercise devices that give users exercise load imitating horse riding have become widespread from medical facilities for rehabilitation purposes to ordinary households as simple exercise equipment that can be used by children and elderly people. Patent Documents 1 and 2 are typical prior arts of this oscillating motion apparatus.

  Patent Document 1 shows a back pain prevention training apparatus that realizes a series of smooth swing patterns using a 6-axis parallel mechanism or the like, and Patent Document 2 swings back and forth between a motor and a link. It is intended to realize left-right swing.

  In such an oscillating type exercise device, as in riding, the heel can be suspended from the seat so that the foot can be placed on the heel so that the riding posture can be easily taken, and the oscillating motion can be applied to the seat. This reduces the possibility that the user will fall off the seat when it is done, but the conventional saddle is forward from the center position in the front-rear direction of the seat (the position that becomes the hip point when sitting) from the viewpoint of maintaining the riding posture. The heel was located about 100 mm on the side.

  However, when it is possible to change the longitudinal angle of the seat from the viewpoint of more effective balance training, when the swinging motion is performed with the seat tilted forward at the position of the heel, the user May not be able to balance the front and back, leading to a dangerous situation.

In addition, the main body in which the mechanism for swinging the seat is placed at the top is often formed to have an inclination that is retracted backward toward the upper side. However, when the seat is swung, The heel with the foot hits the side of the body, which limits the movement of the heel and damages the body and the heel.
Japanese Patent No. 3394890 JP 2001-286578 A

  The present invention has been invented in view of the above-described conventional problems, and an object of the present invention is to provide an oscillating motion apparatus including a heel that can further improve the stability of the user. .

  In order to solve the above-described problems, a swing type exercise device according to the present invention includes a seat on which a user sits and rides, a drive unit that causes the seat to swing, and a suspension that is suspended from both sides of the seat. In the swing type exercise apparatus provided with the heel, the heel is characterized in that it is disposed 150 mm or more forward from the center position of the seat. When the user puts his / her foot on the heel, the foot can be positioned further forward, so that the user can get on the seat without being turned forward even when the seat is leaning forward.

  In the present invention, since the position of the heel is arranged on the front side than usual, even when the seat is tilted forward, the user can step on the foot on the heel and is in a forward-turned state. Accordingly, the swinging motion with the forward tilt of the seat being further increased can be performed without impairing safety. In addition, since the bag is arranged on the front side, the risk of the bag hitting the main body is reduced, so that the exercise can be performed in a more comfortable state, and the main body and the bag are less likely to be damaged.

  Hereinafter, the present invention will be described based on an embodiment shown in the accompanying drawings. The swing type exercise device shown in FIGS. 1 to 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. A main body 1 containing a drive unit 3 for driving is disposed, and a reins 6 are arranged on the front end side of the seat 2 in a semicircular shape and both ends of the seat 2 are connected to the seat 2 so as to be rotatable forward and backward. 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. Protective covers 23 and 23, a panel cover 24 covering the periphery of the operation panel 8, and the like.

  The heel 7 includes a fixing piece 71 fixed to the heel attachment portion 200 on the side surface of the seat frame 20, a connecting piece 72 suspended from the fixing piece 71, and a footrest piece 70 suspended from the connecting piece 72. Thus, the protective cover 23 covers the outer side of the connecting shaft portion of the connecting piece 72 to the fixed 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 through the link plate 41. At this time, when the trajectory of swinging of the connecting shaft 40a between the link plate 41 and the movable plate 40 is T1, the trajectory of swinging of the connecting shaft 40b between the telescopic actuator 45 and the movable plate 40 is T2. As shown in FIG. 9, although both strokes are the same, the upper and lower components are set to be different between the trajectories T1 and T2. Incidentally, the trajectory T1 moves only substantially back and forth, but the trajectory T2 moves up and down in addition to the front and rear because the shaft 303 in the link plate 42 is located behind the shaft 40b. There are many ingredients. In addition, in order to move the rotary plate 39 up and down the position of the shaft 303 serving as the pivotal fulcrum of the link plate 42 in the component for swing driving on the front end side of the movable plate 40, The trajectory T2 takes a route that is shifted up and down between the outward path and the return path.

  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. The seat 2 also swings back and forth and right and left together with the plate 40. The rotational speeds of the output shafts 32 and 33 are set so that the back and forth swing is performed during one cycle of the left and right swing. Therefore, the center point 21a at the center in the left-right direction and lowest in the front-rear direction on the seating surface 21 of the seat 2 is 8 in plan view as shown in FIG. The character is drawn. Further, due to the difference between the trajectories T1 and T2, as shown in FIG. 4B, the central point 21a sinks forward and draws a trajectory in which it returns to the rear while rising.

  In addition, as described above, the trajectory T1 on the rear end side of the seat 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 up and down movement of the seat is performed by moving the front end up and down with the rear side as a fulcrum. When sitting on the seat 2, the user who positions the center of gravity at a position that substantially coincides with the center point of the seat 2 is behind the user. Thus, the movement of the seat 2 moving up and down on the front end side with the rear end side of the seat 2 positioned at a fulcrum as a fulcrum can be sensed more accurately.

  FIG. 4 is 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 the speed changes quickly from a small interval to a large interval. However, it shows that 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 is expanded / contracted by an operation with respect to an operation panel 8 to be described later to move forward and backward, horizontally and backward. In addition to being able to switch between tilt postures, the vertical movement component may be increased or decreased by performing expansion and contraction linked to the above-described back-and-forth and left-and-right swinging.

  Further, if the front-back 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 and the speed of the motor 31.

  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 made 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 becomes horizontal. When the toes are placed on the heel 7, a good posture can be maintained regardless of excessive force on the ankles and knees.

  By the way, in this swing type exercise device, the seat 2 can be swung forwardly as described above, but the distance L from the center point 21a of the seat 2 to the heel is 100 mm. This is not a problem when the seat 2 is swung back and forth and left and right in a horizontal state, but it becomes difficult to maintain a balance on the seat 2 when the seat 2 is swung forward and tilted. If the balance cannot be maintained, the user's body will be leaned forward, and it will be difficult to withstand this state because of the position of the front and back of the foot placed on the heel 7.

  For this reason, in the oscillating motion apparatus of the illustrated example, the distance L from the center point 21a of the seat 2 to the heel 2 is 200 mm. For this reason, even when the seat 2 is tilted forward, the user can securely hold the foot placed on the heel 7 at the front position of the seat 2, so that the posture can be maintained even when the seat 2 is in a forward-turned state. Then, it can ride on the seat 2.

  In addition, since the distance between the main body 1 that houses the drive unit 3 and the heel 7 can be increased, the movement of the foot placed on the heel 7 when the heel 7 hits the main body 1 is restricted. The possibility of damaging the main body 1 is reduced.

  The distance L depends on the value of the maximum forward tilt angle of the seat 2, but is preferably 150 mm or more as long as it can be shifted to the forward tilt state. Further, if the distance L is too long, there is a problem when the sheet 2 is swung back and tilted. Therefore, the distance L is preferably 250 mm or less.

  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 or a preset value, the operation time, and the input weight value.
