In the embodiment shown, seating portion 30 further includes a handle 37. As with base 20, seating portion 30 may be covered with leather, upholstery or a washable fabric or material.
Base 20 is connected to support structure 40. Support structure 40 generally includes a base 41, a pair of front legs 42, a pair of rear legs 43 and a height adjustment mechanism. Base 41 includes a first or front upwardly turned end 41A, a second or rear upwardly turned end 41B, a third or left side 41C and a fourth or right side 41D. In the embodiment shown, left side 41C includes an upwardly extending flange 41E. Base 41 may support a power source, such a battery B.
Front legs 42 include a first or left side front leg 42A and a second or right side front leg 42B. Each of front legs 42a and 42B has a first end 42C and a second end 42D. A drive shaft or linkage 42E extends through legs 42A and 42B. Rear legs 43 include a first or left side rear leg 43A and a second or right side rear leg 43B. Each of rear legs 43A and 43B has a first end having a wheel or roller 43C and a second end 43D. A drive shaft or linkage 43E extends through legs 43A and 43B.
Referring to FIGS. 4, 5A and 5B, height adjustment mechanism 44 generally includes a bracket 45 (not shown in FIGS. 5A and 5B) connected to right side 41D of base 41, a first drive link 47A, a second drive link 47B, a follower 48A and a worm gear 48B. On the right side of support structure 40, second end 42D of front leg 42B is pivotally coupled to one end of first drive link 47A. One end of second drive link 47B is pivotally coupled to second end 43D of rear leg 43B. The opposite ends of drive links 47A and 47B are pivotally coupled to follower 48A. Follower 48A moves along vertically extending worm gear 48B as worm gear 48B rotates. An adjustment knob 48C may be used to rotate worm gear 48B, thereby driving follower 48A along worm gear 48B. In the position shown in FIG. 5A, front legs 42 and rear legs 43 are in the fully retracted position. In order to raise legs 42 and 43 to the position shown in FIG. 5B, adjustment knob 48C is rotated to drive follower 48A upward along worm gear 48B. As this occurs, the ends of drive links 47A and 47B attached to follower 48A are driven upwardly. This pulls second end 42D of front leg 42B and second end 43D of rear leg 43B upwardly. This causes legs 42 and 43 to rotate drive shafts 42E and 43E, driving legs 42 and 43 downward against a support surface and raising support structure 40, along with base 20 and seating portion 30. Regardless of the position of legs 42 and 43, handle 37 can be used to raise legs 43 off the ground and move device 10 on wheels 43C.
Drive mechanism 50 generally includes a housing 51, a support platform 52, a first or front bracket 53, a second or rear bracket 54 a left side link 55 and a right side link 56. Housing 51 is supported on base 40 and encloses a motor and drive system (not shown). The motor and drive system may include gears, drive shafts, cams and other components typically used to impart mechanical motion. The motor and drive system can be of any configuration that imparts motion to seating portion 30 as described below.
Support platform 52 generally includes an upper support plate 52A that is secured to the underside of seating surface 35, a first or left side flange 52B and a second or right side flange 52C. Flanges 52A and 52B extend downwardly and generally perpendicularly to support plate 52A. Bracket 53 includes a body portion 53A, a first or left side flange 53B and a second or right side flange 53C. Flanges 53B and 53C extend generally perpendicularly to body portion 53A. Flanges 53B and 53C are connected at their lower ends to a shaft 53D that extends through housing 51 and are connected at their upper ends to a shaft 53E that extends through flanges 52B and 52C. Bracket 54 includes a body portion 54A, a first or left side flange 54B and a second or right side flange 54C. Flanges 54B and 54C extend generally perpendicularly to body portion 54A.

The lower ends of links 55 and 56 are connected to the output shaft 57 of a drive motor housed within housing 51. The opposite ends of links 55 and 56 are connected to shaft 54E that extends through flanges 52B and 52C. Activating the motor and drive system imparts motion to links 55 and 56 through their lower ends and causes them to move in alternating back and forth motion over an arc segment to replicate the walking gait of a horse. The movement of links 55 and 56 imparts motion to support platform 52, bracket 53 and bracket 54, all of which pivot at their connection points to shafts 53D, 53E and 54E.
Device 10 may be provided with a controller (not shown) to control the motion characteristics produced by drive mechanism 50. For example, the controller can be used to set the simulated speed of a horse produced by drive mechanism 50. In certain embodiments of the invention, the controller is programmable such that it can simulate a ride in which the horse moves at a faster or slower gait or is moving uphill, downhill or across level terrain during different time periods. The controller may be mounted directly to base 20 or seating portion 30 or may be connected to one or both by wires. In other embodiments, the controller communicates with drive mechanism 50 through wireless technology.
Device 10 may be further provided with an adjustment mechanism 60 for aligning the components of drive mechanism 50. In the embodiment shown, adjustment mechanism 60 includes a turnbuckle 61 having a first end 62 connected to housing 51 and a second end 63 connected to support structure 40.
FIGS. 6-11 illustrate the motion of seating portion 30 according to one embodiment of the invention. FIGS. 6 and 11 show device 10 in its centered or neutral position. FIGS. 7, 8 and 10 show device 10 upon activation in which seating portion 30 has moved forward and to the right such that the front right corner tilts downwardly as shown in FIG. 8. As the seat moves backward, the front right corner tilts upwardly and the rear left corner tilts downwardly as shown in FIG. 9. In the next stage of movement, seating portion 30 moves forward with the front two corners tilting downwardly and the two rear corners tilting upwardly. Seating portion 30 then moves rearward such the left front corner tilts upwardly and the right rear corner tilts downwardly. The sequence is then repeated.
In certain embodiments of the invention, device 10 weighs from approximately 30 pounds to approximately 100 pounds. Device 10 may be designed to support persons of any weight.
In one embodiment of a method according to the present invention, an individual places the apparatus on a sufficiently supportive surface, uses the controller mechanism to set the desired ride characteristics (such as speed, time, changes in speed, terrain, etc.) and sits on the seating surface as the apparatus cycles through the programmed ride. The individual may use the apparatus one or more times a day as desired and for as long as desired. Use of the apparatus by the individual soothes and relaxes the individual, thereby reducing the propensity to exhibit the targeted undesired characteristics often associated with autism spectrum disorders.
Although the present invention has been described in detail the same is to be taken by way of example only and not by way of limitation. Numerous changes can be made to the embodiments described without departing from the scope of the invention.
