It is movable and can also be rotated and reciprocated in the left-right direction indicated by arrow P in FIG.

[0018] On the other hand, the drive unit 13 uses two motors (corresponding to the first and second drive sources) 10a and 10b and the rotational force of the output rotary shaft 12a of the motor 10a in the longitudinal direction X of the base 4. Convert these into the reciprocating linear movement, the rotational reciprocating movement around the left and right axes 7a and 7b, the virtual reciprocating rotational movement around the front and rear axes, and the rotational reciprocating movement around the virtual vertical axis. Two drive units 13a and 13b that can be driven are provided. The motors 10a and 10b in this example are vertically installed in the movable frame 6 on the base 8, and the protruding directions of the output rotary shafts 12a and 12b are all upward.

[0019] The first drive unit 13a is for reciprocating rectilinear movement in the front-rear direction X and for rotating back and forth about the left and right shafts 7a, 7b (corresponding to the first conversion means), and the second drive unit 13b is It is for reciprocating movement around the axis and for reciprocating movement around the vertical axis (corresponding to the second conversion means). As shown in FIGS. 2 and 3, the first drive unit 13a includes a first shaft (corresponding to a first left and right axis) 17 connected to the output rotating shaft 12a via a motor gear 11a and a first gear 14. An eccentric crank 19 that is eccentrically connected to the end of the first shaft 17, an arm link 20 that has one end connected to the eccentric crank 19, and the other end is attached to a shaft pin 5c provided on the front link 5a. It consists of Both ends of the first shaft 17 are rotatably supported by the movable frame 6, and the eccentric crank 19 performs an eccentric circular motion with respect to the first shaft 17, thereby allowing the front link 5 a to pass through the arm link 20.

The eccentric crank 19 and the arm link 20 constitute a crank arm.

Further, as shown in FIGS. 3 and 4, the second drive unit 13b includes a second shaft (second left and right shafts) connected to the output rotating shaft 12b via a motor gear 1 lb and a second gear 15. 18) and an eccentric rod 21 whose one end is eccentrically connected to the end of the second shaft 18 and whose other end is rotatably connected to the base 8. Both ends of the second shaft 18 are rotatably supported by the movable mount 6. The eccentric rod 21 is on the left or right side of the movable mount 6. Placed on either side (right side in Figures 3 and 4). The upper end 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 2 lb of the eccentric rod 21 is fixed to the base 8. A pivot pin 28 is pivotally coupled to the coupling bracket 27. Therefore, the rotation of the second shaft 18 causes the upper end portion of the eccentric rod 21 to perform an eccentric circular motion, so that the pedestal 4, i.e., the seat 2, rotates and reciprocates around the longitudinal axis as indicated by the arrow N in FIG. It is possible to reciprocate around the vertical axis as indicated by arrow P in Fig. 3.

[0021] By controlling the operation timings of the motors 10a and 10b, a plurality of motion modes (described later) simulating normal walking, fast walking, etc. can be realized through the drive system. FIG. 5 schematically shows the drive system of the oscillating motion device 1 including a control system. The control system includes a controller (corresponding to a control means) 100 that performs various controls, a selection switch (operating means), a memory 102, a dryer 103a, 103b, sensors 104a, 104b, a lifting mechanism 50. Are electrically connected to each other. The selection switch 101 is for selecting an exercise mode, and is provided on the front side of the seat 2 as shown in FIG. 1 so that the user who makes the selection can easily handle it while seated. Yes. The memory 102 stores in advance the operation timing of the motors 10a and 10b corresponding to each motion mode. The drivers 103a and 103b receive a command signal from the controller 100, and start and stop the motors 10a and 10b and adjust the speed 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 can be detected in a non-contact manner with respect to both shafts 17 and 18, for example, using an encoder. The elevating mechanism 50 performs an elevating operation combined with each motion mode as necessary.

[0022] The operation of the oscillating exercise device 1 will be described below.

[0023] When the selection switch 101 is pressed, the controller 100 reads out one mode selected by the intermediate user of each mode stored in advance in the memory 102 and outputs a command signal corresponding to the mode. Issued to drivers 103a and 103b. In response to the signal from the driver 103a, when the output rotating shaft 12a protruding in one direction of the motor 10a rotates, the first shaft 17 rotates due to the engagement between the motor gear 1la and the first gear 14. 1st shaft 17 times The rotation speed is detected by the sensor 104a and fed back to the controller 100.

[0024] When the output rotating shaft 12b protruding in one direction of the motor 10b is rotated in response to a signal from the driver 103b, the second shaft 18 is rotated by the meshing between the motor gear ib and the second gear 15. To do. The rotation speed of the second shaft 18 is detected by the sensor 104 b and fed back to the controller 100. As a result, stable control can be performed by each operation of the motors 10a and 10b corresponding to each motion mode.

[0025] Then, when the first shaft 17 rotates, the eccentric crank 19 connected to the end of the first shaft 17 performs an eccentric circular motion, and the front link 5a passes through the arm link 20 to move the front left and right shafts 7 to each other. Rotate in the longitudinal direction X around a. At this time, since the rear link 5b cooperates and rotates about the rear left and right shafts 7b, the base 4, that is, the seat 2, reciprocates and swings in the front-rear direction X. On the other hand, the rotation of the second shaft 18 causes the upper end portion of the eccentric rod 21 to perform an eccentric circular motion, and the pedestal 4, that is, the seat 2 rotates and reciprocates around the longitudinal axis 9.

Hereinafter, with reference to FIGS. 6 to 13, examples of the exercise modes that can be selected by the user (first to eighth modes) will be described. In each figure, (a) is the reciprocating linear movement in the front-rear direction, (b) is the reciprocating (left-right) rotational movement around the front and rear X axis, and (c) is the combined motion of (a) and (b). The

First, in the first mode, as shown in FIGS. 6 (a) and 6 (b), when the straight forward / reverse frequency is set to twice the frequency of the left / right rotation and the phase difference is set to 0, as shown in (c) , ∞-shaped movement is obtained. At this time, the controller 100 sets the rotational speed of the motor 10a to be twice the rotational speed of the motor 10b, and operates the motor 10a without causing a time difference.

[0028] In the second mode, as shown in Figs. 7 (a) and 7 (b), when the forward / backward travel is set to twice the frequency of the left / right rotation and the phase difference is-(1Z2) T, As shown, a V-shaped movement is obtained. At this time, the controller 100 operates the motor 10a with the rotational speed of the motor 10a being twice the rotational speed of the motor 10b, giving a time difference— (1Z2) T between the motors 10a and 10b.

[0029] As the third mode, as shown in FIGS. 8 (a) and 8 (b), when the straight forward / reverse is set to a frequency four times that of the left / right rotation and the phase difference is set to 0, as shown in (c), ∞∞-shaped movement is obtained. At this time, the controller 100 sets the rotational speed of the motor 10a to be four times the rotational speed of the motor 10b, and operates the motor 10a and 10b without giving a time difference.

[0030] As the fourth mode, as shown in FIGS. 9 (a) and 9 (b), straight forward and backward movement is performed at a frequency 1Z2 times that of left and right rotation. When it is a number and the phase difference is 0, as shown in (c), an 8-shaped motion is obtained. At this time, the controller 100 sets the rotational speed of the motor 10a to 1Z2 times the rotational speed of the motor 10b, and operates the motor 10a without causing a time difference.

[0031] In the fifth mode, as shown in FIGS. 10 (a) and 10 (b), when the left-right rotation is stopped, as shown in FIG. 10 (c), a single-shaped motion is obtained. At this time, the controller 100 operates only the motor 10a.

[0032] In the sixth mode, as shown in FIGS. 11 (a) and 11 (b), when the forward / backward straight movement is stopped, a linear motion is obtained as shown in (c). At this time, the controller 100 operates only the motor 10b.

[0033] In the seventh mode, as shown in FIGS. 12 (a) and 12 (b), when the frequency of straight forward and backward rotation is the same as that of left and right rotation and the phase difference is (π Ζ2) よう, as shown in (c) In addition, a crab-shaped movement is obtained. At this time, the controller 100 sets the rotation speed of the motor 10a to be the same as the rotation speed of the motor 10b, and operates the motor 10a and 10b with a time difference (π （2) Τ.

[0034] As shown in FIGS. 13 (a) and 13 (b), as the eighth mode, when the forward / backward straight movement and the left / right rotation are stopped, as a matter of course, the movement stops as shown in (c). At this time, the controller 100 does not operate the motors 10a and 10b.

As described above, according to the first embodiment, the movable gantry 6 provided on the base 8 is supported so as to be capable of rotating and reciprocating around the front-rear tilt axis 9 inclined in the front-rear direction (first step). 1 corresponds to the supporting means), and the base 4 fixed to the seat 2 is supported so as to be able to rotate and reciprocate around the left and right shafts 7a and 7b provided on the movable base 6 via the connecting links 5a and 5b. (Corresponds to the second support means). Then, the first drive unit 13a converts the rotational movement of the output rotary shaft 12a of the motor 10a into the reciprocating linear movement of the pedestal 4 in the front-rear direction and the rotary reciprocating movement around the left-right axis through the second support means. At the same time, the rotational force of the output rotating shaft 12b of the motor 10b is converted by the second driving unit 13b into a rotational reciprocating motion around the front and rear axes of the pedestal 4 and a rotational reciprocating motion around the vertical axis through the first support means. . Therefore, according to the first embodiment, four operations can be performed by adding one operation to the conventional three operations described in Patent Document 2, which complicates the exercise and allows the user to select an arbitrary exercise mode. Since it is easy to select the part to be trained for each body, it is possible to obtain a greater fitness effect than before. Can do. In addition, the motors 10a and 10b as drive sources have two forces, which can facilitate control and reduce costs. In addition, the installation space for the drive unit 3 can be reduced to achieve compactness.

[0036] In the above-described embodiment, force and other modes exemplified as eight modes can be added as selectable exercise modes, and conversely, the number of modes can be reduced.

[0037] In the above embodiment, when the user presses the selection switch 101, the controller 10 0 force Force motor 10a, 10b that controls each operation of the motor 10a, 10b according to this selection. May be simply turned on and off manually. Even in that case, it is possible to select a part to be trained for each user's body. The motors 10a and 10b can perform either forward rotation or reverse rotation.

[0038] In the above embodiment, the tilt direction of the front / rear tilt shaft 9 is rearwardly lowered, but may be forwardly lowered. Further, by combining the four movements of the first embodiment with the front / rear inclination angle variable function by the elevating mechanism 50 and controlling the inclination angle of the front / rear and left / right in synchronization with each movement, a more complicated motion can be achieved. It becomes possible, and a greater fitness effect can be obtained. Of course, it may be combined with the extension and contraction movement of the leg 60. Industrial applicability
