ABSTRACT:
A workout horse includes a stationary base frame, a body portion on which a rider sits mounted on an upper support which is movable relative to the base frame, and drive device interconnecting the base frame and the upper support for continuously reciprocating the upper support and thereby the body portion forwards and backwards relative to the base frame along an intended rotary path. For providing the body portion with the simulated movement of a horse at one end of the upper movable support a rigid link is pivotally connected between the upper support and the base frame, the other end of the upper support being supported above the base frame by a separate linkage spaced from the rigid link in the direction of movement of the upper support, and the drive device is mounted offset from the linkage in the direction of movement and comprises two cranks driven by an electric motor, the first crank being connected directly to the upper support to effect the reciprocal motion of the upper support, and the second crank being connected to said linkage between the upper support and the base frame whereby substantially horizontal driving movement of the second crank effects vertical extension or contraction of the linkage thereby changing the attitude of the upper support relative to the base frame, the combined action of the first and second cranks effecting a movement of the upper support and thereby the body portion which simulates the movement of a horse. In a particular embodiment the horse is for use by polo players and the drive device effects a movement of the upper support and thereby the body portion which simulates the natural cantering movement of a polo pony.
