  Embodiments of the present invention will be described below. FIG. 1A is a schematic side view, and FIG. 1B is a bottom view. FIG. 2 (a) is a schematic side view of another leg specification, and FIG. 2 (b) is a front view. FIG. 3 shows a drive system, where FIG. 3 (a) is a schematic plan view and FIG. 3 (b) is a schematic side view.

  The exercise equipment E is a device in which a heel 1 is supported by a leg 2 that is in contact with the ground and a person sits on the heel 1 and swings the heel 1 in the front-rear direction X, the left-right direction Y, and the up-down direction Z to perform horse riding It is.

  In the present invention, the height of the heel 1 is reduced by suppressing the thickness of the drive unit built in the heel 1, so that a person sitting on the heel 1 can perform a tightening operation (exercise) of both feet, and It simplifies the mechanism that swings in the left-right and up-down directions Z, yet allows it to perform a movement on a real horse. Details will be described below.

  A base 3 is fixed to a leg 2 that is in contact with the ground, and a heel drive unit 6 is swingably mounted on the base 3. Specifically, a swing sliding surface 15 is formed on the base 3, and ball bearings 16 provided at, for example, four corners of the rod drive unit 6 are mounted on the swing sliding surface 15 so as to be freely rollable. . The output from the drive motor 4 fixed to the heel drive unit 6 on the base 3 is transmitted in the front-rear direction X and the left-right direction Y through a drive unit described later, and the heel drive unit 6 is horizontally driven in the front-rear direction X and the left-right direction Y. Accordingly, the movement in the vertical direction Z is performed following the swinging sliding surface 15.

  The drive unit is formed in a planar shape to form a planar drive unit 5. Hereinafter, the planar drive unit 5 will be described in detail.

  As shown in FIG. 3, the drive motor 4 is fixed to the base 3 with the axis of the output shaft 7 of the drive motor 4 intersecting the front and rear direction X at about 45 ° in a plan view. The drive motor 4 is driven to rotate in the forward and reverse directions. Output shafts 7 are protruded on both sides of the drive motor 4. A worm gear 31 is attached to both ends of the output shaft 7. A worm wheel 32 is rotatably supported on the base 3, and the worm gear 31 is engaged with the worm wheel 32 so that the rotation of the drive motor 4 is greatly reduced to rotate the worm wheel 32.

  In the worm wheel 32, an eccentric vertical axis 9 is erected at a position eccentric from the rotational vertical axis F thereof. An eccentric longitudinal axis 9 is pivotally connected to both ends of a swinging horizontal link 12 in which a pair of horizontal links 11 and 11 are connected so that the angle can be changed. The planar drive unit 5 is configured as the drive point P. The drive point P is pivotally connected to the eaves drive unit 6 as a drive shaft 33.

  Thus, the rotational output of the drive motor 4 is decelerated in the reduction gear mechanism 8 of the worm gear 31 and the worm wheel 32 to decelerate and rotate the worm wheel 32, and the oscillating horizontal in which the eccentric longitudinal axes 9 and 9 are pivotally connected. The link 12 is swung horizontally to change the opening angle θ between the horizontal links 11 and 11, the drive shaft 33 is driven and moved in the front-rear direction X and the left-right direction Y, and such drive force is applied to the eaves drive unit 6.

The reduction gear mechanism 8 is provided with eccentric longitudinal axes 9, 9 that are eccentric with respect to the rotational longitudinal axis F of the reduction gear 10. The eccentric vertical axis 9 is pivotally connected to both ends of a swinging horizontal link 12 in which the horizontal links 11 and 11 are connected so as to be capable of changing the angle, and the pivoting connection point of the swinging horizontal link 12 is connected to the planar drive unit 5. Since the drive point P is used, an eccentric vertical axis 9 that decelerates the high-speed rotation of the output shaft 7 in the reduction gear mechanism 8 and is eccentric with respect to the rotational vertical axis F of the reduction gear 10 and the reduction gear 10 is obtained. The crank mechanism is configured to cause the horizontal link 11 to perform a crank motion, and the pivot connection position of the swinging horizontal link 12 pivotally attached to the pair of horizontal links 11 and 11 is set as a driving point P in the front-rear direction X and the substantially horizontal plane.
