No. 11/115,880, filed on Apr. 26, 2005 now abandoned, which claims the benefit of U.S. Provisional Patent Application No. 60/566,057, filed on Apr. 27, 2004, and claims the benefit of U.S. Provisional Patent Application No. 60/566,057, filed on Apr. 27, 2004, each of which is expressly incorporated herein in its entirety by reference thereto.


FIELD OF THE INVENTION
The present invention relates generally to an amusement ride, and relates more particularly to a ride having carriages that revolve around a central unit in which the carriages bounce up and down as they revolve.
BACKGROUND INFORMATION
The growth of the amusement industry has led to the development of a wide variety of rides designed for children and adults. Among the wide variety of rides, one of the historically more prevalent types is the carousel, in which carriages that may seat one or more passengers revolve around a central axial unit. Originally, the passenger carriages were designed to resemble horses or coaches, but over time, carousels have been updated to include carriages designed to imitate modern vehicles, such as automobiles. Among the more common of the automobile designs is the ‘dune buggy’, popular with children.
One of the main limitations of the typical carousel ride is the monotonous quality of its passenger motion. The passenger simply revolves around the central unit, usually at a constant speed, with rather stilted lateral and vertical motion. This lack of versatility has, over time, made the typical carousel ride a less attractive ride in comparison to other ride types introduced to amusement parks.

DETAILED DESCRIPTION
Those skilled in the art will gain an appreciation of the present invention from a reading of the following description when viewed in conjunction with the accompanying drawings of FIGS. 1 to 4, inclusive. The individual reference characters designate the same or similar elements throughout the several views.
Referring now to FIG. 1, there is shown a schematic perspective view of an example embodiment of an amusement ride 1 according to the present invention. As shown, a plurality of carriages, e.g., 5a, 5b and 5c, are coupled to a central unit 10 by respective shafts or cantilever arms 7a, 7b and 7c that radiate outwardly from and are pivotably attached to the central unit 10. The carriages 5a, 5b, 5c are suspended above the ground by the shafts 7a, 7b, 7c. The carriages may be implemented in the shape of, e.g., miniature cars or buggies. The size of the buggies may be dimensioned so as to enable seating of two adults or children of a desired age range in both a front seating area and a back seating area. As indicated in an example embodiment of the amusement ride 1 shown in top plan view in FIG. 3, the ride 1 may include six carriages 5a, 5b, 5c, 5d; 5e, 5f, in total, that are each pivotably coupled to the central unit 10 by respective shafts 7a, 7b, 7c, 7d, 7e, 7f. The carriages 5a, 5b, 5c, 5d, 5e, 5f are uniformly spaced circumferentially, forming a hexagonal pattern about the central unit 10. It should be understood and appreciated that any number of carriages and shafts may be provided and that the carriages may take any desired form, including, e.g., a motor vehicle, boat, canoe, raft, bus, train, bicycle, motorcycle, tricycle, horse or other animal, sled, toboggan, skateboard, roller skate, plane, hang glider, roller coaster, spaceship, rocket, etc.
The central unit 10 includes a motor and rotates about its central axis. As the central unit 10 rotates and the carriages 5a, 5b, 5c travel in circumferential paths substantially in a horizontal plane about the central axis, each carriage periodically encounters one or more structures or arrangements, described in greater detail below, that cause the carriages to pivot in an upward direction. When a carriage includes passengers, the weight of the passengers counteracts the upward momentum and movement of the carriage so that the upward motion reaches an upper limit and then the carriage begins to pivot downward. This downward movement is in turn limited by an additional bumper structure off of which the carriage may bounce or ‘jump’ in a semi-elastic manner. Due to its momentum, as the carriage bounces it may retrace its upward path. This motion is repeated cyclically so that the carriage oscillates between an upper limit position and the stopper structure. This oscillatory movement may be damped to control the speed and smoothness of the oscillation. During this oscillation the passenger(s) experiences an undulating vertical jumping motion in addition to the horizontal revolving motion.
This vertical motion is schematically illustrated in FIG. 2. In FIG. 2, one of the carriages 5a is illustrated as positioned substantially below horizontal plane A′ A′′, while another carriage 5d is illustrated as positioned substantially above the plane A′ A′′. Thus, while the carriages fixedly revolve around the central axis at the same speed, each carriage pivots up or down independently, and at any given time, each carriage may therefore be at a different phase of oscillation with respect to the other carriages.
FIG. 4 illustrates in greater detail an example embodiment of an amusement ride according to the present invention and particularly illustrates an example mechanism for generating the vertical oscillatory motion of the carriages. The central unit 10 is positioned on a platform 35 and is rotatably coupled thereto. The central unit 10 includes or is coupled to an energy source, e.g., an electrical power source, and also includes a motor mechanism 40 that enables the unit to rotate around its vertical central axis 11 with respect to the platform 35. The platform 35, which provides support for the ride, may be moved between locations by wheels 30. Once a desired location is selected, retractable legs, e.g., 22a, 22d positioned beneath the platform 35 are extended to fix the ride 1 in place upon the floor and to level the ride 1. Each carriage is pivotably coupled by a shaft e.g., 7a, 7d to a plate fixture 17a, 17d rigidly attached to the external surface of the central unit 10. In addition, radially extending lower arms 8a, 8d positioned below the shafts 7a, 7d are also pivotably coupled to the plate fixtures 17a, 17d. Rollers 16a, 16d are rotatably fixed to the distal ends of each lower arm 8a, 8d. Horizontal support plates 18a, 18d are positioned on top of the rollers 16a, 16d and are fixed to the top surfaces of the lower arms 8a, 8d. On top of each of the support plates 18a, 18d, a bumper 14a, 14d and a bellows 12a, 12d is fixedly positioned. The bellows 12a, 12d may also be fixedly attached to lower surfaces of the shafts 7a, 7d or may be arranged to abut or strike the lower surface of the shafts 7a, 7d during the oscillation movement. Each of the rollers 16a, 16d is configured to engage at least one arrangement for inducing a vertical motion 20 positioned along the circumference of the platform 35. Upon engagement with a roller, the arrangement 20 exerts an upward force on the roller e.g., 16a that is transmitted to the lower arm 8a and then to the shaft 7a by means of the bellows 12a. In the example embodiment depicted, the arrangement 20 is implemented as an upwardly sloping ramp. Additional bumper elements 42a, 42d may be provided for the lower arms 8a, 8d. Bellows 12a, 12d may be, e.g., hydraulic, pneumatic, etc., and may be selectively inflatable and deflatable for loading and unloading, for adjustment during riding by the operator or a rider, etc. A pump system, compressor system and/or an accumulator system may be provided to inflate and deflate the bellows 12a, 12d. During loading of passengers, the bellows 12a, 12d may be in a deflated condition, and, immediately before the ride begins, the bellows 12a, 12d may be inflated. Then, when the ride is completed, the bellows 12a, 12d may again be deflated for unloading and subsequent loading. Sensors, e.g., proximity sensors, magnetic sensors, switches, etc., may be provided to prohibit the carriages from stopping on the ramp when the ride cycle is coming to an end.
The operation of the amusement ride may be explained as follows with reference to the above-described structures. As the central unit 10 rotates, the assemblies coupled to the central unit revolve circumferentially, whereby the rollers 16a, 16d periodically come into contact with the ramp 20. During this contact, the rollers 16a, 16d are lifted. Initially, the upward movement of the rollers 16a, 16d is transmitted the lower arms 8a, 8d, which pivot upwardly. As the lower arms 8a, 8b pivot, they apply force to the bellows 12a, 12d, which begin to compress. Since the compression of the bellows 12a, 12d is gradual, the upward movement of the lower arms is temporarily transmitted to the shafts 7a, 7b which therefore acquire a degree of upward movement in sympathy with the movement of the rollers 16a, 16d over the ramp 20. When the rollers 16a, 16d reach the end of the ramp 20, which may end abruptly, the rollers 16a, 16d they fall off in a downwardly, causing the lower arms 8a, 8b to pivot downwardly in relation to the shafts 7a, 7b, which in turn causes the bellows to expand. After a certain time, the shafts 7a, 7b reach an upper limit position and begin a downward motion under the weight of the passengers in the carriages. As the shafts pivot downwardly in relation to the lower arms 8a, 8b (since the lower arms are not forced downwards by the weight of the passengers), they compress the bellows 12a, 12d, which damp the downward movement of the carriages. Along their downward trajectory, the shafts 7a, 7d eventually come into contact with bumpers 14a, 14d which may include an elastic material such as rubber that induce the shafts to rebound upwardly. Since the shafts 7a, 7d come into contact with the bumpers 14a, 14d while the lower arms 8a, 8d do not, the shafts 7a, 7d acquire an upward movement relative to the lower arms 8a, 8d which spreads the shafts 7a, 7d apart from the lower arms 8a, 8d and causes the bellows 12a, 12b to expand. This oscillation continues during the duration of the ride. The oscillation may be considered to be periodic in the sense that a ramp 20 provided at one or more locations imparts the oscillating movement periodically as each carriage 5a, etc., passes the ramp(s) 20. The ramp 20 may have an upwardly sloped portion in the direction of travel of the carriages 5a, etc., which may have a simple profile as a wedge or a more complex profile, e.g., undulating. The upwardly sloped portion may end abruptly or may end more gradually depending upon the desired performance of the ride.
In the foregoing manner, the differential pivoting of the shafts 7a, 7d with respect to the lower arms 8a, 8d (and vice versa) generates a cyclic expansion and compression of the bellows 12a, 12d. In sum, the periodic effect of the ramps, the weight of the carriages and the bumpers, together with the associated cyclic damping effect of the expansion and compression of the bellows, brings about a damped oscillatory motion of the carriages, which the passengers experience as a smooth and undulating ‘jumping around’ motion.
