  This invention is invented in view of said conventional problem, Comprising: It aims at providing the exercise device which can perform the effective motion according to the user.

  In order to solve the above problems, an exercise device according to the present invention includes a movable part for moving a user's body and a drive part for moving the movable part, and the drive part is connected to the user via the movable part. Is an exercise device that can vary the exercise given to the user, and stores information acquisition means for acquiring the body information as the user's biological information and exercise ability information, and preferable operation information of the corresponding movable means. The motion database, the motion acquisition means for acquiring the motion status of the movable part, the motion status acquired by the motion acquisition means, and the physical information acquired by the information acquisition means are referred to the motion database, and preferably the movable part And a control unit that acquires operation parameter information about the operation and outputs the information. The user can know the operating parameters preferable for the user.

  The information indicated by the output means may be provided with means for notifying the display or voice.

  Further, the control unit may cause the drive unit to perform an operation based on the acquired operation parameter information.

  As the information acquisition means, a means for obtaining physical information by data input by the user can be used, but a sensor may be used, and the sensor at this time is attached to clothes worn by the user. Can be suitably used.

  In the present invention, since the user can know what the movement of the movable part according to the user's biological information and exercise ability information is, it is effective for the user. An operation that can be performed can be performed by the movable unit.

  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 corresponding to the movable portion in the present invention is composed of 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. 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 footrest 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.

  In addition, an acceleration sensor AS (see FIG. 1) for detecting the movement of the seat 2 that is a movable portion is attached to the inside of the seat 2, and the acceleration sensor AS acquires an operation status of the movable portion. Is functioning as

  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.

  Next, physical information acquisition means provided in the exercise apparatus will be described. The exercise apparatus incorporates a body composition meter T for acquiring the user's biological information, and the user's exercise ability information. The sensor S for acquiring is incorporated.

  The body composition meter T measures the weight of the user who sits on the seat 2 with the load sensor S1 placed on the upper surface of the seat surface 21 and the heel 7, and puts the foot on the heel 7, and the user's palm and sole. An electrode M for allowing a weak current to flow through the human body is provided on the reins 6 and 7 that are touched with each other, and the body composition is measured using impedance. With this body composition meter T, body weight, body fat, visceral fat, skeletal muscle rate, basal metabolism, and the like can be obtained as biological information.

  The sensor S for acquiring athletic ability information includes a load sensor S1 disposed at a position where the inner thigh touches when the user sits on the seat 2 on the side of the seat 2, and a sensor S2 for detecting the movement of the user. As the sensor S2, a plurality of strain sensors or acceleration sensors attached to the clothes W worn by the user as shown in FIG. 7 can be used. Although attached to the clothes W here, it may be attached in any way as long as it can be easily attached to the user's body. However, when the sensor S2 is attached to the clothing W that is in close contact with the body, it is possible to feed back which muscle is loosened and which muscle is tense.

  On the other hand, as shown in FIG. 1, a control unit C including a drive control unit C1 that controls the drive unit 3 includes a storage unit C2, an athletic ability calculation unit C3, an output unit C4, and a data table C5 that is an operation database. The operation input unit in the operation panel 8, the various sensors S, and the body composition meter T are connected to each other, and a notification unit H and a display unit 88 that are operated by an output from the output unit C4. Is connected.

  The athletic ability calculation unit C3 determines the user for the movement of the seat 2 from the movement of the seat 2 obtained from the acceleration sensor AS, the movement of the user obtained from the sensor S2, and the force measured by the weight sensor S1. The user's motor ability (for example, exercise level Ex, muscle strength, endurance, flexibility, balance, muscle endurance) is estimated from the responsiveness of the movement, comparison of movement, and magnitude of the force. FIG. 9 shows an example of determination when these athletic abilities are selected in three stages of large, medium and small.

  The data table 5 is composed of parameter data relating to the operation of the seat 2 such as what speed is preferable for the movement given to the seat 2 according to the value of the physical information and what value is preferable for the inclination angle of the seat 2. It stores the operation database that has been processed. This motion database is created from measurement of physical information of a large number of subjects, observations of user's myoelectric potential and calorie consumption, user's movements, etc. when the motion parameters of the seat 2 are changed. is there.

  Now, when the user gets on the seat 2 and puts his / her foot on the heel 7 and grasps the reins 6, and the movement of the seat 2 by the drive unit 3 is operated at a preset speed and an inclination angle, the control unit C has a body composition. The biometric information is acquired from the meter T, and the athletic ability calculation unit C3 calculates the athletic ability based on the information acquired from the weighted sensors S1 and S2, and the biometric information and athletic ability information are stored in the storage unit K. . Also, by referring to the data table C5, preferable parameter data corresponding to the obtained biological information and exercise ability information is acquired.

  The control unit C compares the speed data given to the drive control unit C1 and the inclination angle data of the seat 2 with the parameter data, and the comparison result and preferable parameter data are provided in the operation panel 8. It is displayed on the display unit 88. At this time, it is preferable that the notification unit H also notifies the same content by voice. For example, “Because a faster movement is preferable for you, set the speed to ~ and the seat to the forward tilted state. . " From the viewpoint of the user, it is possible to know what kind of movement is performed on the seat 2 so that an effective movement can be performed.

  The control unit C may automatically change to the operation parameter obtained from the data table C5. However, the change in this case is preferably performed after notifying the user in advance using the display unit 88 or the notification unit H.

  The display unit 88 under the control of the control unit C is provided in the operation panel 8. If the display mode is changed, the weight measured by the body composition meter T (when the height is input separately). BMI value), body fat percentage, visceral fat level, skeletal muscle percentage, basal metabolism, etc. are displayed. At this time, it is possible to read past measurement values from the storage unit K and display them on the display unit 88, for example, in a state where the previous measurement values are written together with the current measurement values. desirable.

  Since the amount of exercise and calorie consumption can be calculated from the output of the sensor S2 and the load sensor S1 and the exercise time, a display mode for these data may be provided, and these data are also stored in the storage unit K. It may be possible to display the past exercise history. The amount of exercise and calorie consumption can also be calculated from the motor load of the drive unit 3, and the exercise amount is exercise Ex (Ex = Mets × Time Mets: which is a unit proposed in the 2006 Exercise Guidelines of the Ministry of Health, Labor and Welfare) It is preferable to use a unit of intensity of exercise.

  Although a body composition meter T is provided as a biological information acquisition means for acquiring biological information, a sphygmomanometer that measures blood pressure and pulse, a blood glucose meter that optically measures blood glucose level, and optically measures sebum thickness It may be equipped with a sebum thickness gauge. These biological information acquisition means are convenient if they are connected to the exercise device by wire or wirelessly and transfer measurement information to the control unit C on the exercise device side, and are particularly attached to the tip of the finger. A type capable of measuring the above can be suitably used.

  In the above description, the exercise apparatus itself measures biological information and exercise ability information. However, the information may be separately received from the biological information measurement apparatus and exercise ability measurement apparatus. Such information may be taken in, for example, through the communication interface 92, or may be taken in by reading out information from the information medium in which the information is recorded through the information medium interface 91. It is preferable that the operation database can be updated through these interfaces 91 and 92.

  Furthermore, the biometric information and athletic ability information may be information that the user inputs the biometric information and athletic ability information in the form of answering an inquiry. FIG. 8 shows an example of the operation panel 8 capable of inputting the information. In the figure, 80 is a power switch, 81 is a height adjustment switch for adjusting the height of the seat 2 by operating an electric slide unit (not shown), and 82 is an inclination angle of the seat 2 by operating the telescopic actuator 45. Is an angle adjustment switch for adjusting the speed, 83 is a speed adjustment switch for adjusting the speed by changing the rotation speed of the motor 31 of the drive unit 3, 84 is a selection switch group for inputting information, and 85 is a swing operation. An operation mode selection switch 86 for suppressing to beginners' orientation, 86 is an operation mode changeover switch for switching the exercise intensity by the swinging operation, and the display unit 88 is composed of a liquid crystal display and is set to the information input mode. For example, an inquiry question is displayed on the display unit 88 and information is input using the selection switch group 84.

  It is preferable that the athletic ability information in this case is obtained by inputting a result when the user performs a movement that is a measure of flexibility and muscle strength, for example.

  In the above embodiment, the swing type exercise device that loads the user with exercise simulating riding is shown. However, the present invention is not limited to this embodiment, and as shown in FIG.
