The upper end of the front link 5a is rotatably fixed to the upper shaft pin 4a provided at the front end of the pedestal 4, and the lower end of the front link 5a of the side plate 16 of the movable pedestal 6 is fixed. It is rotatably fixed to the lower shaft pin 7a provided in the front end portion. The upper end of the rear link 5b is rotatably fixed to the upper shaft pin 4b provided at the rear end of the pedestal 4, and the lower end of the rear link 5b is the side plate 16 of the movable pedestal 6. It is rotatably fixed to the lower shaft pin 7b provided at the rear end of the shaft. Each of the lower shaft pins 7a and 7b at the front and rear constitutes a left and right shaft that rotatably supports the linking links 5a and 5b around the axis line in the left and right directions Y. Thus, the pedestal 4 has a left and right shaft ( 7a, 7b) reciprocation rotation movement is possible in the front-back direction shown by the arrow M of FIG.

As shown in FIG.2 and FIG.4, the bearing board 24 is erected at the both ends of the base 8, and the connection board 25 which opposes the bearing board 24 is respectively at the both ends of the movable stand 6, respectively. It is installed side by side. The connecting plate 25 is pivotably connected to the axial plate 24 by the front and rear inclination shafts 9 inclined so as to be parallel to the base 8. The front and rear inclination shafts 9 are disposed at two front and rear positions in the center of the base 8 to support the movable pedestal 6 around the front and rear inclination shafts 9 so that the pedestal 4 is inclined back and forth. Rotational reciprocation is possible in the left-right direction shown by the arrow N of FIG. 4 around the axis 9, and rotational reciprocation is also possible in the left-right direction shown by the arrow P of FIG.

On the other hand, the drive part 13 uses the two motors (equivalent to the 1st, 2nd drive source) 10a, 10b, and the rotational force of the output rotation shaft 12a of the motor 10a to the front-back direction of the base 4 (X). ) Is converted into a reciprocating linear movement, a rotary reciprocating movement around the left and right shafts 7a and 7b, a rotary reciprocating movement around an imaginary front and rear axis, and a rotary reciprocating movement around an imaginary vertical axis, and the four motions combined Two drive parts 13a and 13b which enable driving of (2) are provided. The motors 10a and 10b of this example are placed in the movable pedestal 6 on the base 8, and the protruding directions of these output rotation shafts 12a and 12b are all upward.

The 1st drive part 13a is for the reciprocation linear movement of the front-back direction X, and the rotary reciprocation movement around the left-right axis 7a, 7b (corresponds to a 1st conversion means), and the 2nd drive part 13b is the front-back direction It is for rotational reciprocating movement about an axis, and rotational reciprocation movement about an up-and-down shaft (equivalent to 2nd conversion means). As shown in FIGS. 2 and 3, the first driving unit 13a corresponds to a first shaft (first left and right shafts) connected to the output rotation shaft 12a via the motor gear 11a and the first gear 14. (17), an eccentric crank (19) connected eccentrically to an end of the first shaft (17), and one end of which is connected to the eccentric crank (19), and the other end of the shaft pin provided at the front link (5a). It consists of an arm link 20 which is rotatably fixed to 5c. Both ends of the first shaft 17 are supported by the movable pedestal 6 so as to be rotatable, and the eccentric crank 19 performs the eccentric circular motion with respect to the first shaft 17 to thereby open the arm link 20. All the links 5a reciprocate in the front-rear direction X through this. For this reason, the pedestal 4 connected to the connection link 5, ie, the seat 2, can be rocked in the direction shown by the arrow M of FIGS. The crank arm is composed of an eccentric crank 19 and an arm link 20.

Moreover, as shown in FIG.3 and FIG.4, the 2nd drive part 13b is equivalent to the 2nd shaft (2nd left-right axis | shaft) connected to the output rotating shaft 12b via the motor gear 11b and the 2nd gear 15.

Both ends of the second shaft 18 are rotatably supported by the movable pedestal 6. The eccentric rod 21 is disposed on either the left side or the right side of the movable pedestal 6 (the right side in Figs. 3 and 4). The upper end portion 21a of the eccentric rod 21 is eccentrically connected to the end of the second shaft 18 by the shaft pin 29 shown in FIG. 4, and the lower end portion 21b of the eccentric rod 21 is connected to the base ( The axial pin 28 is rotatably connected to the L-shaped connecting bracket 27 fixed to 8). Therefore, when the upper end part of the eccentric rod 21 performs an eccentric circular motion by the rotation of the 2nd shaft 18, the pedestal 4, ie, the seat 2, as shown by the arrow N of FIG. Rotational reciprocation movement around an axis is possible, and rotation reciprocation movement also becomes possible about an up-and-down axis | shaft as shown by the arrow P of FIG.

Then, by controlling the operation timings of the motors 10a and 10b, a plurality of exercise modes (described later), which are modeled after the normal walking, the fast walking, and the like, can be realized through the drive system. FIG. 5 is a diagram schematically showing a control system in the drive system of the oscillating motion device 1. The control system includes a selection switch (corresponding to an operation means) 101, a memory 102, a driver 103a, 103b, a sensor 104a, a controller (corresponding to a control means) 100 that performs various controls. 104b) and the elevating mechanism 50 are electrically connected, respectively. The selection switch 101 is for selecting an exercise mode, and is provided on the front side of the seat 2 so as to be easily handled in a seated state by a user who makes the selection. The memory 102 stores in advance the operation timings of the motors 10a and 10b according to the respective exercise modes. The drivers 103a and 103b receive a command signal from the controller 100 and perform the start stop of the motors 10a and 10b and the speed adjustment during rotation. The sensors 104a and 104b detect the rotational speeds of the first shaft 17 and the second shaft 18. As shown in Figs. 2 and 3, these sensors 104a and 104b are capable of non-contact detection with respect to both shafts 17 and 18 using, for example, an encoder. The elevating mechanism 50 performs the elevating operation in combination with each exercise mode as necessary.

The operation of the oscillating exercise device 1 will be described below.

When the selection switch 101 is pressed, the controller 100 reads out one of the modes selected by the user from each of the modes previously stored in the memory 102, and sends a command signal corresponding to the mode to the drivers 103a and 103b. Shown in When the output rotary shaft 12a projecting in one direction of the motor 10a rotates in response to the signal from the driver 103a, the first shaft is engaged by the motor gear 11a and the first gear 14. (17) rotates. The rotational speed of the first shaft 17 is detected by the sensor 104a and fed back to the controller 100.

Moreover, when the output rotary shaft 12b which protrudes in one direction of the motor 10b by receiving the signal from the driver 103b rotates, the 2nd shaft will be engaged by the motor gear 11b and the 2nd gear 15 engaged. 18 rotates. The rotational speed of the second shaft 18 is detected by the sensor 104b and fed back to the controller 100. For this reason, stable control is performed with respect to each operation | movement of the motors 10a and 10b according to each movement mode.

And when the 1st shaft 17 rotates, the eccentric crank 19 connected to the edge part of the 1st shaft 17 will perform an eccentric circular motion, and the front link 5a will be front-right and left-side through the arm link 20. It rotates in the front-back direction X about the axis 7a. At this time, the rear link 5b cooperates and rotates around the rear left and right shafts 7b, so that the pedestal 4, that is, the seat 2 reciprocates and swings in the front-back direction X. On the other hand, by the rotation of the second shaft 18, the upper end of the eccentric rod 21 performs an eccentric circular motion, and the base 4, that is, the seat 2, rotates reciprocally around the front and rear axis 9.

Hereinafter, with reference to FIGS. 6-13, the example (1st-8th mode) of each exercise mode which a user can select is demonstrated. In addition, in each figure, (a) shows the reciprocating linear movement of the front-back direction, (b) shows the (left-right) rotational reciprocation movement around the front-back (X) axis, and (c) shows the combined motion of (a) (b) .

At this time, the controller 100 makes the rotation speed of the motor 10a twice the rotation speed of the motor 10b, and operates without giving time difference between both motors 10a and 10b.

As a second mode, as shown in Fig. 7 (a) (b), when the front and rear straight line is set to twice the frequency of left and right rotation and the phase difference is-(1/2) T, it is shown in (c). Likewise, you can get a V-shaped exercise. At this time, the controller 100 makes the rotation speed of the motor 10a twice the rotation speed of the motor 10b, and operates it by giving time difference-(1/2) T between the two motors 10a, 10b. .

As a third mode, as shown in Fig. 8 (a) and (b), when the front and rear straight line is set to four times the frequency of left and right rotation and the phase difference is 0, as shown in (c),? Can get exercise. At this time, the controller 100 makes the rotation speed of the motor 10a four times the rotation speed of the motor 10b, and operates it without giving time difference between both motors 10a and 10b.

As a fourth mode, as shown in Fig. 9 (a) (b), when the front and rear straight line is set to the frequency of 1/2 times of the left and right rotation, and the phase difference is 0, as shown in (c), it is 8 characters. You can get a workout. At this time, the controller 100 makes the rotation speed of the motor 10a be 1/2 times the rotation speed of the motor 10b, and operates without giving time difference between both motors 10a and 10b.

As a fifth mode, as shown in Fig. 10 (a) and (b), when the left and right rotations are stopped, one-shaped movement can be obtained as shown in (c). At this time, the controller 100 operates only the motor 10a.

As the sixth mode, as shown in Fig. 11 (a) and (b), when the straight forward and backward movement is stopped, as shown in (c), one-shaped movement can be obtained. At this time, the controller 100 operates only the motor 10b.

As a seventh mode, as shown in Fig. 12 (a) (b), when the frequency of the straight forward and backward rotation is the same and the phase difference is (π / 2) T, as shown in (c), ○ You can get a chair-shaped exercise. At this time, the controller 100 makes the rotational speed of the motor 10a the same as the rotational speed of the motor 10b, and operates by giving time difference (π / 2) T between the two motors 10a, 10b.

As the eighth mode, as shown in Fig. 13 (a) and (b), when the forward, backward and left and right rotations are stopped, as a matter of course, the movement is not performed as shown in (c). At this time, the controller 100 does not operate the motors 10a and 10b together.

As described above, according to the first embodiment, the movable pedestal 6 provided on the base 8 is rotatably supported around the front and rear inclination shaft 9 inclined in the front-rear direction (first Corresponding to the supporting means), the base 4 fixed to the seat 2 has a rotary reciprocating movement around the left and right shafts 7a, 7b provided on the movable pedestal 6 via connecting links 5a, 5b. It is possibly supported (corresponds to the second supporting means). Then, by the first drive unit 13a, the rotational movement of the output rotating shaft 12a of the motor 10a is reciprocated linear movement in the front-rear direction of the pedestal 4 and the rotation around the left and right shafts through the second supporting means. In addition to being converted to reciprocating movement, the rotational movement of the output rotating shaft 12b of the motor 10b is rotated reciprocally around the front and rear shafts of the pedestal 4 via the first supporting means by the second drive unit 13b. And rotational reciprocating movement around the vertical axis. Therefore, according to the first embodiment, four operations in which one operation is added to the conventional three operations described in Patent Document 2 become possible, and the movement is complicated, and the part to be trained for each user's body by the selection of an arbitrary exercise mode. Since the selection of is made easy, a larger fitness effect can be obtained than before. In addition, although there are two motors 10a and 10b as drive sources, the control and ease of cost can be reduced. Moreover, the installation space of the drive device 3 can be narrowed and compactness can also be attained.

In addition, although eight modes were illustrated as the exercise mode which can be selected in the said embodiment, other modes can also be added and the number of modes can also be reduced on the contrary.

Moreover, in the said embodiment, when the user pushes the selection switch 101, although the controller 100 controls each operation of the motors 10a and 10b according to this selection, both motors 10a and 10b You can simply turn on and off manually. Even in that case, it is possible to select a site to be trained for each user's body. The motors 10a and 10b can perform both forward rotation and reverse rotation.

Moreover, in the said embodiment, although the inclination direction of the front-back inclination shaft 9 is inclined backward, you may incline forward. Further, by combining the front and rear inclination angle variable function by the elevating mechanism 50 with the four operations of the first embodiment, and controlling the inclination angles of the front, rear, left and right in synchronization with each operation, a more complicated movement becomes possible. A greater fitness effect can be achieved. It goes without saying that it may be combined with the stretching movement of the leg portion 60.
