Description

  The present invention keeps the balance of the user by swinging the seat on which the user is seated to give the user an exercise load imitating riding or swinging a stand on which the user stands. The present invention relates to an oscillating-type exercise device that forces this.

  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 this type of oscillating motion apparatus, the seat can be oscillated not only in a horizontal state but also in a forwardly inclined state or a backwardly inclined state, By changing the exercise intensity by changing it, there is a demand for maintaining a high level of balance sensation and further increasing the amount of exercise.

However, for beginners who use the swing type exercise device for the first time, if swinging with a high degree of forward tilt or swinging at a high speed is made, there is a risk that excessive motion will be forced, There is also a possibility that the user's body may fall off the seat without following the movement of the seat.
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 that can be used with peace of mind even by beginners.

  In order to solve the above-described problems, a swing type exercise device according to the present invention includes a movable part on which a user rides, a drive part that causes the movable part to perform a swing movement, and a control unit that performs drive control of the drive part. And an instruction input means for designating a beginner mode in an oscillating exercise apparatus in which at least one of the exercise intensity and operation time of the oscillating motion by the driving unit and the posture of the movable unit is variable. The control means includes a variable range of the motion intensity of the swing motion, a variable range of the operation time, and a variable range of the posture of the movable part when an instruction input for specifying the beginner mode is made from the instruction input means. It is characterized by limiting at least one.

  If beginner mode is specified, the exercise intensity (including speed) can be suppressed, the operation time can be shortened, and the posture is limited to a level state, so there is no excessive exercise, Moreover, it does not become difficult to get on the movable part.

  In the present invention, by specifying the beginner mode, the variable range of the exercise intensity of the oscillating motion, the variable range of the operation time, or the variable range of the posture of the movable part is limited. Or, it can eliminate the state that the operation time is long or the posture that makes it difficult to maintain the balance, the state where the exercise intensity (including the speed) is suppressed, the state where the operation time is shortened, or The user can receive a swinging motion in an easy-to-maintain state, and this does not force the user to exercise excessively. A situation in which the user does not slide down from the movable part without unavoidable does not occur, and even a beginner can use it with peace of mind.

  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. 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. Thus, a roll driving unit is configured.

  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. 33b is connected to a connecting link 36 having one end connected to the link plate 41 to form a pitch driving unit.

  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 the 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. 11 (b), the central point 21a sinks forward and draws a trajectory that 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. 11 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. 11, the acceleration during the forward movement is larger than the acceleration during the backward movement. 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 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. The roll drive unit also serves as the yaw drive unit.

  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 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. 12 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, which is a display means, displays the tilt state of the seat 2, displays the speed adjustment state, displays the operation time, displays the exercise intensity, displays the calculated amount of exercise (calorie consumption), By displaying the posture of the seat 2 that is tilted back and forth due to the expansion and contraction, a display of what value is applied to which muscle of the abdominal muscles / back muscles / thigh front / thigh rear of the human body is performed.

  Next, the operation when the beginner mode is designated by the operation mode selection switch 85 will be described. If the angle adjustment switch 82 is operated among the various switches arranged on the operation panel 8, the telescopic actuator 45 is operated as described above to change the posture of the seat 2 from the forward tilt state to the rear tilt state. If the speed adjustment switch 83 is operated, the swinging operation speed can be changed, and if the operation mode changeover switch 86 is further operated, “soft” is obtained by combining the change in speed and the change in posture. The three modes of “Hard” and “Powerful” can be switched. However, when the beginner mode is designated, the posture change, the speed change and the exercise intensity change by the switches 82, 83, 86 are described. Limits are applied to reduce the angle change range centering on the horizontal state for posture changes, and the slowest to medium for speed changes. It is variable only within the range up to the speed of degrees, and only “soft” can be selected as the exercise intensity, and the posture (angle), speed and exercise intensity at the time when the beginner mode is specified If it is out of the above range, first, it is set within the above range. Further, the continuous operation time is limited within a predetermined time.

  For such a limitation, data describing the posture range, speed range, motion intensity range, and motion time limit values permitted in the beginner mode is written in the data table C3 in the control circuit C shown in FIG. When the beginner mode is instructed by the operation mode selection switch 85, the arithmetic control unit C1 reads the data from the data table C3, and based on this data, the posture change range, the speed change range, the exercise intensity change range, and the operation time This limit value is set, and each operation control is performed within the set range. The count timer C4 in FIG. 1 is for measuring the operation time, and C2 is for holding the weight value and the value of the exercise amount obtained by calculation.

  In the above-described embodiment, the swing type exercise device that loads the user with exercise simulating riding is shown, but the present invention is not limited to this form, and the table on which the user stands is swung. Thus, for example, a load imitating a user simulating surfing, and a walking motion was simulated by swinging a seat on which the user sits and moving up and down a footrest on which each user's foot is individually placed. The present invention can also be applied to a device that exercises a user.
