Japanese Patent No. 3394890 JP 2001-286578 A

  The present invention has been invented in view of the above-described conventional problems, and can easily determine whether or not the user's movement appropriately corresponds to the periodic movement of the movable part. It is an object of the present invention to provide an exercise device that allows a user to perform effective exercise.

  In order to solve the above problems, an exercise device according to the present invention performs a periodic operation in an exercise device including a movable part on which a user rides and a drive unit that causes the movable part to perform a periodic operation. The motion detection means for detecting the body motion of the user riding on the movable part, and the period of the user's body motion detected by the motion detection means and the period of the periodic motion of the movable part by the drive unit are compared. It has a feature in that it comprises a rhythm feeling judging means for obtaining the user's rhythm feeling from the period difference. It is possible to determine whether or not the user is making a rhythmic movement synchronized with the periodic movement of the movable part.

  And in the thing provided with the alerting | reporting means which notifies a user of the said period difference, it can prompt a user to perform an appropriate motion.

  The present invention relates to a cycle of the user's body movement detected by the motion detection means for detecting the body movement of the user riding on the movable section performing the periodic movement, and the periodic movement of the movable section by the driving unit. Rhythm sense determination means for obtaining the rhythm sense of the user from the difference between the cycles of the rhythm sense of the user, so that the user performs a rhythmic movement synchronized with the periodic movement of the movable part. From this determination result, the user can know whether his / her movement corresponding to the movement of the movable part is appropriate, and keep the appropriate movement Thus, effective exercise can be performed.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. First, from the mechanical point of view of the exercise device, the exercise device shown in FIG. 2 and FIG. 3 uses the seat 2 on which the user sits on the seat 2 by periodically swinging the seat 2 back and forth and left and right. This exercise allows the person to perform exercises for balance training. The seat 2 has a shape imitating the back of a horse or a saddle, and the upper surface is a seating surface. A main body 1 containing a drive unit 3 is arranged. On the front end side of the seat 2 is disposed a reins 6 having a semicircular arc shape and both ends pivotably connected to the seat 2 back and forth, and an operation panel 8. In addition, ridges 7 and 7 are suspended from both front sides of the seat 2, respectively.

  The main body 1 is provided with grounding legs 15 at four corners and a drive unit 3 (described later) accommodated in a portion that rises obliquely rearward from the central portion so that its vertical position can be adjusted. And covers 17 and 18.

  On the other hand, the seat 2 includes a seating surface 21 attached to the upper surface of the seat frame 20 and protective covers 23 and 23 attached to the left and right of the seat frame 20. Further, the flange 7 includes a fixed piece 71 fixed to the side surface of the sheet frame 20, a connecting piece 72 suspended from the fixed piece 71, and a leg piece 70 suspended from the connecting piece 72.

  As shown in FIGS. 3 to 5, 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, The main body 1 is attached to the main body 1 by being connected to a support frame (not shown) disposed in the main body 1 in the main body 1 so as to be rotatable about the axis A 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. It is connected.

  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 and 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 reciprocate around the axis of the axis A.

  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 the connecting shaft 40a between the link plate 41 and the movable plate 40 is T1, and the trajectory of the connecting shaft 40b between the telescopic actuator 45 and the movable plate 40 is T2, the trajectory of the connecting shaft 40a is shown in FIG. As shown, although the strokes of both T1 and T2 are the same, the vertical component is set to be different between the two 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. 6B, the central point 21a sinks forward and draws a trajectory returning to the rear while rising.

  FIG. 6 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 large, 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. 6, 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 made about the axis of the axis A in the front-rear direction lower than the rear side. Although the plate 40 swings left and right in the same angular range on both the front side and the rear side, since the front side is longer than the rear side with respect to the front and rear axis A, the left and right movements of the front end side of the movable plate 40 are performed. The stroke 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 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 extended / contracted by an operation on an operation panel 8 described later to change the front / rear inclination angle of the seat 2. Then, the forward tilting posture, the horizontal posture, and the backward tilting posture are switched. It is also possible to increase or decrease the vertical movement component by performing expansion and contraction in conjunction with the above-described swinging back and forth and left and right.

  FIG. 7 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 S provided on the seat 2 and the input weight value, and regarding the degree of load on each muscle accompanying the posture change of the front and rear inclination of the seat 2, Data on how the myoelectric potential of each muscle changes due to the difference in the front and rear tilt angle of the seat 2 and the speed of the motor 31 is taken and determined based on this data.

  By the way, the user sitting on the seat 2 that performs the periodic operation as described above performs a movement for maintaining balance as the seat 2 swings. When the user's body motion is a motion synchronized with the periodic motion of the seat 2, the most effective motion is performed. However, as described above, it is difficult for the user to recognize whether his / her body movement is synchronized with the periodic movement of the seat 2.

  For this reason, in this exercise apparatus, motion detection means S1 for detecting the body movement of the user who is riding on the movable part performing the periodic motion is provided, and rhythmic feeling determination means D is provided. C in FIG. 1 is a control unit that controls the operation of the drive unit 3. As the motion detection means S1, load sensors provided on the left and right eaves 7 and 7 can be preferably used, but in addition, an acceleration sensor mounted on the user's body, a load attached to the reins 6 and the seat surface 21. Sensors can also be used.

  FIG. 8 shows an output example for approximately 10 seconds when the load sensors provided on the left and right saddles 7 and 7 are the motion detection means S1. In the figure, A is the output of the load sensor provided on the right side ridge 7 and B is the left side ridge 7, and it can be seen that the detected load increases and decreases periodically.

  On the other hand, since the acceleration sensor S2 is provided on the seat 2 that is periodically oscillated by the drive unit 3, the above-described oscillation cycle of the seat 2 is determined from the output change of the acceleration sensor S2. Can be detected. Note that the swing period of the seat 2 may be detected based on the movement of the mechanism unit 3 instead of the acceleration sensor S2.

  Here, the rhythm feeling determination means D compares the period of body movement obtained as the output of the motion detection means S1 with the period of movement of the seat 2 obtained as the output of the acceleration sensor S2, and uses the difference between the periods. For example, if the deviation of the peak value is within a predetermined time (for example, 0.2 seconds), a determination that the rhythm is good is output. The periodic change patterns themselves may be compared to determine that the sense of rhythm is good if the correlation coefficient is 0.9 or more, for example. Such a determination result is notified to the user using the display 88 or to the user by voice notification.

  This notification is not only about whether the movement of the user follows and synchronizes with the movement of the seat 2, but for example, when the deviation of the peak value is large, the notification that the body movement delay is large. It is preferable to be able to go and inform the user what the user's movement is for the desired movement. Further, the display 88 may be used to perform a display for visually confirming the period difference. As such display, it is possible to use a display in which, for example, a graph of the movement in the front-rear direction of the movement of the user and a graph of the movement in the front-rear direction of the seat 2 are superimposed.

  In the above 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 type, and the platform on which the user stands is periodically arranged. For example, as shown in FIG. 9, a footrest 90 for swinging the seat 2 on which the user sits and individually placing each foot of the user is placed. It can also be applied to those that load the user with an exercise simulating a walking movement by vertically moving the. As the motion detection means S1 in these, a load sensor provided on the footrest 90 and a load sensor provided for assisting balance maintenance and provided on a handle or string held by the user can be used.

  As described above, the display 88 provided on the operation panel 8 displays a period difference (phase difference) and provides information to assist the user in determining how to move his / her own movement. Anything that can be communicated can be used suitably, but in addition, it has a connection interface with memory cards, personal computers, mobile phones, etc., and can customize the background image etc. to the user's preference Provide functions, calculate and display the amount of exercise of the user from the output value of the load sensor, display the past exercise history, and display whether there is a change in the user's sense of rhythm between the previous time and this time If the user can perform the exercise, the user can raise awareness of the exercise using the exercise apparatus.

  Furthermore, it is good also as what incorporates the game sensation that a virtual character is nurtured when it is possible to exercise on the rhythm well.
