Patent Description:
Amusement parks may have various entertainment attractions. One type of entertainment attraction may be a carousel ride system. The carousel ride system may include a turntable and multiple figures (e.g., seats for riders) that rotate with the turntable. In some carousel ride systems, the multiple figures may move up and down relative to the turntable as the multiple figures rotate with the turntable.

<CIT> describes a ride including a first turntable assembly including a first turntable and a drive mechanism operable to rotate the first turntable about a rotation axis extending vertically through the first turntable. The ride apparatus includes a second turntable assembly that is supported on the first turntable, and the second turntable assembly includes a second turntable and a drive mechanism operable to rotate the secondary turntable about a rotation axis extending vertically through the second turntable. The ride apparatus includes a number of passenger vehicles mounted on the second turntable that are rotated to maintain an angular orientation to cause the vehicles to face a focal point or area on a projection surface provided about the turntables. The drive mechanisms are operable to independently rotate the first and second turntables about the rotation axes.

In an embodiment, a carousel ride system includes a first rotatable platform and multiple second rotatable platforms. Each second rotatable platform of the multiple second rotatable platforms is positioned within a respective opening in the first rotatable platform. A first drive system is configured to drive rotation of the first rotatable platform and multiple second drive assemblies are configured to drive rotation of the multiple second rotatable platforms. Multiple figures extend over the multiple second rotatable platforms and multiple figure drive assemblies are configured to independently lift and rotate the multiple figures relative to the multiple second rotatable platforms. One or more processors are configured to coordinate operation of the first drive system, the multiple second drive assemblies, and the multiple figure drive assemblies to maintain the multiple figures in a forward-facing orientation relative to a direction of travel of the first rotatable platform during operation of the carousel ride system.

In an embodiment, a method of operating a carousel ride system includes driving rotation of a first rotatable platform about a first rotational axis using a first drive system positioned between the first rotatable platform and a ground relative to a vertical axis. The method also includes driving rotation of multiple second rotatable platforms about respective second rotational axes using multiple second drive assemblies, wherein each second rotatable platform of the plurality of second rotatable platforms is positioned within a respective opening in the first rotatable platform, wherein each second drive assembly of the multiple second drive assemblies is positioned between a respective one of the multiple second rotatable platforms and the ground relative to the vertical axis. The method further includes driving rotation and lift of multiple figures that extend over the multiple second rotatable platforms using multiple figure drive assemblies positioned between the multiple second rotatable platforms and the ground relative to the vertical axis and in a coordinated manner to maintain the multiple figures in a forward- facing orientation relative to a direction of travel of the first rotatable platform during operation of the carousel ride system.

The present disclosure is related to a carousel ride system that may be used in an amusement park. The carousel ride system may include a first platform (e.g., first rotatable platform), multiple second platforms (e.g., second rotatable platforms), and multiple figures (e.g., seats for riders). The figures may move up and down relative to the first platform as the figures rotate with the first platform. At least some of the figures may also rotate with a respective second platform. In an embodiment, each figure may lift (e.g., move up and down) and rotate independently from one another while maintaining a consistent forward-facing orientation to improve ride entertainment and/or comfort, for example.

In an embodiment, carousel ride operations may be programmable so that different operational modes can be performed during ride operation. For instance, some figures may lift and/or rotate, while other figures may not lift and/or rotate. In an embodiment, one or more groups of figures may lift and/or rotate in a coordinated manner, such as to provide a group of riders (e.g., a family) a racing-type experience, to face toward one another at certain times or throughout ride operation, or the like. Such operational modes may further enhance the ride experience.

With the foregoing in mind, <FIG> is a perspective view of an embodiment of a carousel ride system <NUM> that includes a first platform <NUM> (e.g., first rotatable platform), multiple second platforms <NUM> (e.g., second rotatable platforms), and multiple figures <NUM> (e.g., seats for riders) each mounted on a respective pole <NUM> (e.g., rigid support pole). As shown, a first set of the figures <NUM>, such as figures 16A, are positioned on the first platform <NUM> and may move up and down relative to the first platform <NUM> as the figures 16A rotate with the first platform <NUM>. A second set of the figures <NUM>, such as figures 16B, are each positioned on a respective second platform <NUM> and may move up and down relative to the respective second platform <NUM> as the figure 16B rotates with the respective second platform <NUM>. Because the second platforms <NUM> are supported within openings formed in the first platform <NUM> and/or are carried to rotate with the first platform <NUM>, it should be appreciated that each of the figures (e.g., figures 16A and 16B) may rotate with the first platform <NUM> and may move up and down relative to the first platform <NUM> and/or the second platform <NUM>. Additionally, each of the figures <NUM> (e.g., figures 16A and 16B) may lift and rotate independently from one another via a respective pole <NUM> while rotating with the first platform <NUM> and/or a respective second platform <NUM>.

The first platform <NUM> may be a rotatable platform or table supported and driven by a first platform drive system (e.g., unified first platform drive system), which may include multiple first platform drive assemblies <NUM> that are located under the first platform <NUM>. The first platform drive system, which may include the first platform drive assemblies <NUM>, may drive the first platform <NUM> to rotate about a first rotational axis <NUM> that passes through a center of the first platform <NUM> and that may be parallel to a vertical axis <NUM>. For example, as shown, the first platform drive assemblies <NUM> may be positioned underneath the first platform <NUM> (e.g., between the first platform <NUM> and the ground; underneath a radially-outer edge portion of the first platform <NUM>), and the first platform drive assemblies <NUM> may be arranged circumferentially about the first rotational axis <NUM>.

In the illustrated embodiment of <FIG>, six first platform drive assemblies <NUM> may be used to support and drive the first platform <NUM> to move on a rail <NUM> (e.g., track, path) in a circumferential direction <NUM>. The rail <NUM> may be a circular track positioned on a base (e.g., ground; steel-reinforced concrete slab). Each of the first platform drive assemblies <NUM> may include physically-separate drive units. For example, as shown in <FIG>, each of the first platform drive assemblies <NUM> includes two physically-separate drive units. It should be appreciated that any of a variety of different drive assembly configurations (e.g., more or less than six first platform drive assemblies, each having more or less than two drive units) may be implemented. However, multiple first platform drive assemblies <NUM> that each have multiple drive units may advantageously enable the carousel ride system <NUM> to continue to operate and drive rotation of the first platform <NUM> even after one or a portion of the drive assemblies <NUM> fail.

As illustrated, the drive units in each first platform drive assembly <NUM> may be connected by a connection beam <NUM>. Each first platform drive assembly <NUM> may be connected to the first platform <NUM> by one or more support beams <NUM>. The use of multiple first platform drive assemblies <NUM> along with the multiple connection beams <NUM> and multiple support beams <NUM> may help to distribute weight (e.g., of the first platform <NUM>, the second platforms <NUM>, the figures <NUM>, riders) across the rail <NUM> and the base.

The multiple second platforms <NUM> may be a set of rotatable platforms or tables supported and driven by respective second platform drive assemblies <NUM>. As shown, a single second platform drive assembly <NUM> may be located under a respective second platform <NUM> and may be used to support and drive the respective second platform <NUM>. Each second platform drive assembly <NUM> may drive the respective second platform <NUM> to rotate about a respective second rotational axis (e.g., second rotational axis 56A or 56B of a corresponding second platform <NUM>) and that may be parallel to the vertical axis <NUM> and/or the first rotational axis <NUM>.

As illustrated, each second platform drive assembly <NUM> may be positioned on a radially-extending beam <NUM> (e.g., spoke). In an embodiment, each radially-extending beam <NUM> may include one or more rods that extend radially between a respective connection beam <NUM> and a center post located under the first platform <NUM>. Each radially-extending beam <NUM> may be fixed to (e.g., non-rotatable with respect to) the respective connection beam <NUM> and the center post (e.g., the center post may rotate relative to the ground), or each radially-extending beam <NUM> may be fixed to the respective connection beam <NUM> and may be rotatably coupled to (e.g., rotatable with respect to) the center post (e.g., the center post may be stationary relative to the ground). Each second platform drive assembly <NUM> may be connected to a respective second platform <NUM> by one or more support beams <NUM>. Additionally, each second platform drive assembly <NUM> may be connected to a respective first platform drive assembly <NUM> by one or more additional connection beams <NUM>. As shown, the second platform drive assemblies <NUM> may be positioned underneath the respective second platform <NUM> (e.g., between the respective second platform <NUM> and the ground; underneath a center portion of the respective second platform <NUM>), and the second platform drive assemblies <NUM> may be radially-inwardly of the first platform drive assemblies <NUM> (e.g., between the first platform drive assemblies <NUM> and the center post).

Each second platform <NUM> may be positioned within a respective platform opening in the first platform <NUM>. In an embodiment, each second platform <NUM> is not supported by the first platform <NUM>, and is instead fully supported by its second platform drive assembly <NUM> and associated structures (e.g., the radially-extending beam <NUM>) located underneath the first platform <NUM> and/or the second platform <NUM>. In an embodiment, a radial gap is provided between a radially-outer surface of the second platform <NUM> and a radially-inner surface that defines the respective platform opening. In such cases, roller bearings may be provided within the radial gap to facilitate rotation of the second platform <NUM> relative to the first platform <NUM>. It should also be appreciated that the second platforms <NUM> may be at least partially supported on the first platform <NUM>, or the first platform <NUM> may be at least partially supported on the second platforms <NUM>.

Each of the multiple figures <NUM> may be mounted on a corresponding pole <NUM>. The poles <NUM> may not extend upward above the figures <NUM> and/or may not be attach to a ceiling or other structure above the figures <NUM>. During loading and unloading operations of the carousel ride system <NUM>, the carousel riders may travel (e.g., walk) on the first platform <NUM> and/or the second platform <NUM> to reach the multiple figures <NUM>. Each pole <NUM> may extend through a respective opening (e.g., pole opening) in the first platform <NUM> or one of the second platforms <NUM>. In some cases, at least a portion of the figure <NUM> may extend through the respective opening along with the pole <NUM>, for example. Thus, at least the portion of the figure <NUM> may be positioned below the first platform <NUM> or one of the second platforms <NUM> relative to the vertical axis <NUM> (e.g., between the first platform <NUM> or one of the second platforms <NUM> and the ground). It should be appreciated that each pole <NUM> may be positioned so that at least a portion of the figure <NUM> attached thereto extends over at least one of the first platform <NUM> or the second platforms <NUM>.

The first platform <NUM> and the second platforms <NUM> may be carried to travel together about the first rotational axis <NUM>. Thus, operation of the first platform drive assemblies <NUM> to drive rotation of the first platform <NUM> about the first rotational axis <NUM> may result in rotation of the multiple figures 16A positioned on the first platform <NUM> and the multiple figures 16B positioned on the second platforms <NUM> about the first rotational axis <NUM>. Additionally, rotation of each second platform <NUM> about a respective rotational axis (e.g., second rotational axis 56A or 56B of the second platform <NUM>) may drive rotation of corresponding multiple figures 16B positioned on the second platform <NUM> about the respective second rotational axis 56A or 56B. To facilitate discussion and image clarity, only some of the multiple figures <NUM> and corresponding components (e.g., pole <NUM>) are illustrated in <FIG>. However, it should be appreciated that the multiple figures <NUM> and corresponding components may be distributed at various locations about the first platform <NUM> and the second platforms <NUM>. The first platform <NUM> and the second platforms <NUM> may rotate at the same or different rotational rates and/or in the same or different directions (e.g., in the circumferential direction <NUM> or in a direction opposite the circumferential direction <NUM>). Additionally, the second platforms <NUM> may rotate at the same or different rotational rates and/or in the same or different directions as compared to one another. Furthermore, the rotational rates and/or the directions may vary throughout the ride operation.

As mentioned previously, each of the multiple figures <NUM> may be supported and driven, via a respective pole <NUM>, by a figure drive assembly <NUM> (e.g., lift and rotate system or assembly). The figure drive assembly <NUM> may be supported by and/or concealed inside a housing unit <NUM> that is located under the first platform <NUM> and/or a respective second platform <NUM>. Each housing unit <NUM> may be attached (e.g., mounted, such as via one or more fasteners) to a bottom side of the first platform <NUM> or the respective second platform <NUM>, and thus, the figure drive assemblies <NUM> are positioned underneath the first platform <NUM> or the respective second platform <NUM> (e.g., between the first platform <NUM> or the respective second platform <NUM> and the ground). In this way, the housing unit <NUM> may support and carry the figure drive assembly <NUM> with the first platform <NUM> or the respective second platform <NUM>. The housing unit <NUM> may also provide protection for the figure drive assembly <NUM> from dirt, moisture, accidental contact, or the like.

Each figure drive assembly <NUM> may drive a corresponding figure <NUM> to move up and down along a respective figure axis <NUM> (e.g., parallel to the respective pole <NUM>, the vertical axis <NUM>, the first rotational axis <NUM>, and/or the second rotational axis 56A or 56B). Each figure drive assembly <NUM> may also drive the corresponding figure <NUM> to rotate about the respective figure axis <NUM>. The figure drive assembly <NUM> may increase the operational flexibility of the carousel ride system <NUM>, thus enriching the ride experience for riders.

During ride operations, at least the first platform <NUM>, a respective center of each of the second platforms <NUM>, the multiple figures 16A, the first platform drive assemblies <NUM>, and a respective center of each of the second platform drive assemblies <NUM> may rotate together in the circumferential direction <NUM>. During this rotation, the multiple figures <NUM> may move up and down along the figure axes <NUM>. In an embodiment, the multiple figures <NUM> may also rotate about the figure axes <NUM>. The multiple figures <NUM> may move up and down at the same or different lift rates, may move up and down through the same or different lift heights (e.g., relative to the first platform <NUM> or the respective second platform <NUM>), may rotate at the same or different rotational rates, and/or may rotate in the same or different directions (e.g., in the circumferential direction <NUM> or in a direction opposite the circumferential direction <NUM>) as compared to one another. Furthermore, the lift rates, the lift heights, the rotational rates, and/or the directions may vary throughout the ride operation.

A variety of support and drive assemblies, systems, or components may be generally hidden from the view of the riders. For example, the first platform drive assemblies <NUM>, the rail <NUM>, the connection beams <NUM>, the support beams <NUM>, the second platform drive assemblies <NUM>, the radially-extending beams <NUM>, the support beams <NUM>, the additional connection beams <NUM>, the figure drive assemblies <NUM>, and at least a portion of each pole <NUM> may be positioned vertically below the first platform <NUM> and/or the multiple second platforms <NUM>, enclosed by a cover (e.g., wall), and/or positioned within a receptacle (e.g., opening or hole) formed in the ground. Thus, as the riders approach the carousel ride system <NUM>, travel across the first platform <NUM>, and the multiple second platforms <NUM> during loading and unloading operations, and ride on the multiple figures <NUM> during ride operations, the riders may not see the variety of support and drive assemblies, systems, or components mentioned above, the cover, and/or the ground surrounding the receptacle. While at least some portions of the hidden features are shown as generally transparent to facilitate discussion and to enable visualization of components of the carousel ride system <NUM>, it should be appreciated that at least some portions of such hidden features may not be transparent.

Additionally, it should be appreciated that various drive assemblies described in preceding sections may be powered, controlled, and coordinated by a power system and a control system (e.g., electronic control system). For example, with reference to <FIG>, a power system <NUM> and a controller <NUM> may be used in the carousel ride system <NUM>. The power system <NUM> and the controller <NUM> may be positioned under the first platform <NUM> and the second platforms <NUM>, being generally hidden from the view of the riders. However, the power system <NUM> and the controller <NUM> may be positioned in any suitable location. The power system <NUM> may provide electrical power for operating the various drive assemblies, including the first platform drive assemblies <NUM>, the second platform drive assemblies <NUM>, the figure drive assemblies <NUM>, and so on. The controller <NUM> may control and coordinate the operations of the various drive assemblies mentioned above, and/or the operations of the power system <NUM>. For example, the controller <NUM> may control, via the second platform drive assemblies <NUM> and the figure drive assemblies <NUM>, orientations of the figures <NUM> so that the riders riding on the figures <NUM> (e.g., figures 16B that may rotate with a corresponding second platform <NUM> in addition to rotating with the first platform <NUM> during ride operations) may consistently face forward (e.g., in the circumferential direction <NUM>; in a direction of travel of the first platform <NUM>) while each of the figures <NUM> are lifting and rotating individually.

In an embodiment, the figures <NUM> (e.g., all figures <NUM> or a group of figures <NUM>, such as all figures <NUM> that rotate with one of the second platforms <NUM>) may lift and/or rotate in a coordinated manner, such as to provide a group of riders (e.g., a family) a racing-type experience, to face toward one another at certain times or throughout ride operation, or the like. For example, as the first platform <NUM> rotates about its first rotational axis <NUM> and the second platform <NUM> rotates about its second rotational axis <NUM>, a first figure <NUM> on the second platform <NUM> may move forward of the other figures <NUM> on the second platform <NUM>, then the first figure <NUM> on the second platform <NUM> may move rearward relative to the other figures on the second platform <NUM> as a second figure <NUM> on the second platform <NUM> moves forward of the other figures <NUM> on the second platform <NUM>, and so on. Thus, the riders may have a racing-type experience throughout ride operations. The controller <NUM> may control the figure drive assemblies <NUM> to consistently face forward and/or so that the figures <NUM> are raised as they move forward of the other figures <NUM> on the second platform <NUM> (e.g., reach a peak at a forward-most position or while in front of the other figures <NUM>) and so that the figures <NUM> are lowered as they move rearward of the other figures on the second platform <NUM> (e.g., reach a valley at a rearward-most position or while behind the other figures <NUM>) to enhance the racing-type experience.

As illustrated, the controller <NUM> may include one or more processors <NUM>, a memory device <NUM>, and an input device <NUM>. The processor(s) <NUM> may provide control signals to certain controllable devices and components (e.g., motors, actuators, brakes, or the like) associated with the various drive assemblies (e.g., the first platform drive assemblies <NUM>, the second platform drive assemblies <NUM>, and the figure drive assemblies <NUM>) and other relevant assemblies/systems. The processor(s) <NUM> may be configured to receive inputs via an input device <NUM> (e.g., from a ride operator; from a rider; from another device) and to provide the control signals to the controllable devices and components in response to the inputs. For example, the processor(s) <NUM> may receive an input that indicates that the riders have climbed onto the multiple figures <NUM> and that a loading operation is complete. In response, the processor(s) <NUM> may provide control signals to the first platform drive assemblies <NUM>, the second platform drive assemblies <NUM>, and the figure drive assemblies <NUM> to initiate new ride operations. In an embodiment, the processors(s) <NUM> may receive an input (e.g., prior to the ride or during the ride, such as via an input device on the figure <NUM>) that indicates a characteristic and/or a preference of a rider of a particular figure, such as a characteristic and/or preference related to a lift rate, a lift height, a rotational rate, and/or a rotational direction for the figure <NUM>. In response, the processor(s) <NUM> may provide control signals to the respective figure drive assembly <NUM> to adjust the figure <NUM> in accordance with the characteristic and/or preference (e.g., a higher lift rate, a lift height and/or a rotational rate for an adult, and a lower lift rate, a lift height, and/or rotational rate for a child). In an embodiment, the processor(s) <NUM> may receive an input from another device (e.g., computing system), such as an input related to achievements of the rider in the amusement park, such as a number of points earned in a game, a number of rides completed, purchases made, or the like. In response, the processor(s) <NUM> may provide control signals to the respective figure drive assembly <NUM> to adjust the figure <NUM> in accordance with the achievements (e.g., a higher lift rate, a lift height and/or a rotational rate for a first rider with more achievements, and a lower lift rate, a lift height, and/or rotational rate for a second rider with fewer achievements). In an embodiment, the processor(s) <NUM> may receive an input (e.g., from a rider(s) in a group of riders; prior to the ride or during the ride) that indicates a group preference, such as selection of one of multiple group movements for the figures 16B on a respective one of the second platforms <NUM> (e.g., face forward for a racing experience, face toward one another for a family experience). In response, the processor(s) <NUM> may provide control signals to the respective figure drive assemblies <NUM> to adjust the figures 16B in a coordinated manner to provide the selected group movement. Any combination of inputs and corresponding control features may be implemented.

In operation, the carousel ride system <NUM> may continuously move between loading operations, ride operations, and unloading operations. Certain operations (e.g., ride operations) may be automated and/or controlled on one or more timers (e.g., timed schedules). For example, once rotation of the first platform <NUM> commences, rotations of the second platforms <NUM> may commence simultaneously or with a delay time. The rotation of the first platform <NUM> may continue for a time period (e.g., predetermined or operator-controlled time period, such as <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, or more minutes). The rotations of the second platforms <NUM> may continue for the same or a different time period. When the time period of the first platform <NUM> ends, the processor(s) <NUM> may provide the control signals to the controllable devices and components (e.g., motors, actuators, brakes, or the like) of the first platform <NUM>, the second platforms <NUM>, and the figures <NUM> to stop movement (e.g., rotations and/or lifts) simultaneously or in a predetermined time sequence.

The memory device <NUM> may include one or more tangible, non-transitory, computer-readable media that store instructions executable by the processor(s) <NUM>. For example, the memory device <NUM> may include random access memory (RAM), read only memory (ROM), rewritable non-volatile memory such as flash memory, hard drives, optical discs, and/or the like. Additionally, the processor(s) <NUM> may include one or more general purpose microprocessors, one or more application specific processors (ASICs), one or more field programmable gate arrays (FPGAs), or any combination thereof.

Additionally or alternatively, individual (or distributed) controllers may be implemented. For example, the first platform drive assemblies <NUM>, the second platform drive assemblies <NUM>, the figure drive assemblies <NUM>, and/or the power system <NUM> may have dedicated controllers (to be described in detail later) respectively. The dedicated controllers may be communicatively connected to the controller <NUM>. The controller <NUM> may control and coordinate, via the respective dedicated controllers, the operations of the first platform drive assemblies <NUM>, the second platform drive assemblies <NUM>, the figure drive assemblies <NUM>, and/or the power system <NUM>.

<FIG> is a perspective view of a portion of one of the first platform drive assemblies <NUM>, as described in <FIG>. For example, the portion of the first platform drive assembly <NUM> shown here may be a drive unit <NUM>, which is one of the two separated drive units in the configuration described previously. The drive unit <NUM> may be used to drive the first platform <NUM> to rotate about a center axis of the first platform drive assemblies <NUM> (e.g., the first rotational axis <NUM>). The drive unit <NUM> may be used to support and drive the first platform <NUM> to move on the rail <NUM> in the circumferential direction <NUM>. The rail <NUM> may be secured on a base using mounting bolts and/or other fasteners, for example.

As illustrated, the drive unit <NUM> may be connected to another drive unit in the same first platform drive assembly <NUM> by the connection beam <NUM>. The drive unit <NUM> may include a frame assembly <NUM>, one or more drive wheels <NUM>, and a drive motor <NUM>. The frame assembly <NUM> may provide support for the connection beam <NUM>. Additionally, the frame assembly <NUM> may provide mounting points for the drive wheel(s) <NUM> and the drive motor <NUM>. The drive motor <NUM> may be any type of electrical motor that generates rotational force used to drive the drive wheel(s) <NUM> to rotate. Although not shown here, the drive unit <NUM> may include other components, such as one or more brake units, one or more biasing members, one or more gearboxes, and the like.

The frame assembly <NUM> may include a frame <NUM>, one or more support beams <NUM>, and a jack <NUM>. The frame <NUM> may provide direct support for the connection beam <NUM>. The support beams <NUM> may be coupled to (e.g., vertically suspended from) the frame <NUM>. The support beams <NUM> may be connected horizontally via a bracket <NUM>. The support beams <NUM> may or may not contact the surface of the rail <NUM> during ride operations. The jack <NUM> may be coupled to (e.g., vertically suspended from) a bottom of the bracket <NUM>).

In an embodiment, the support beams <NUM>, or a portion (e.g., bottom portion) of the support beams <NUM>, may be made of certain metal or plastic material that has specific abrasion and resistance properties. For example, ultra-high molecular weight (UHMW) polyethylene, which has high abrasion and impact resistance properties, may be used in the support beams <NUM>. In the cases where the support beams <NUM> may contact the surface of the rail <NUM> during ride operations to support the frame <NUM> and other components, the support beams <NUM> (e.g., made of the UHMW polyethylene or other suitable material) may resist wear, friction, and corrosion, thus reducing maintenance cost (e.g., with less power consumption) and extending equipment/component life.

In an embodiment, a gap <NUM> (e.g., along the vertical axis <NUM>) may be provided between the support beams <NUM> and a top surface of the rail <NUM> (e.g., during default or expected operation; while a wear level or thickness of the drive wheels <NUM> is above a threshold). In such cases, a sensor (e.g. contact sensor or position sensor) and/or a scraper (or scraper blade) may be installed on the support beams <NUM>. The sensor may be used to detect whether the support beams <NUM> contact or are within a threshold distance of the top surface of the rail <NUM>. The sensor may generate a signal in response to the detected event, and the signal may indicate a corresponding (e.g., nearest) drive wheel <NUM> has experienced too much wear (e.g., the wear level or the thickness is below the threshold) during ride operations. The scraper or scraper blade may be used to clean the rail <NUM> to remove possible debris or fallen objects during ride operations to avoid potential halt/damage to the first platform drive wheel <NUM>.

As illustrated, the jack <NUM> may have a pre-attached pad, which may prevent possible delamination (e.g., to the rail <NUM>) during ride operations when one or more drive wheels <NUM> wear out or a similar situation occurs. In some cases, the jack <NUM> may be a portable jack for maintenance (e.g. used to support the frame <NUM> and other components while replacing the drive wheel <NUM>).

Additionally, it should be appreciated that the operations of the first platform drive assembly <NUM> may be coordinated and controlled by a controller <NUM> (e.g., electronic controller). The controller <NUM> may control and coordinate the operations of the drive units <NUM>. For example, the controller <NUM> may control the drive motors <NUM> and/or the brakes to start or stop the rotation of the first platform <NUM>. In an embodiment, the controller <NUM> may adjust speed settings of the drive motors <NUM> to control a rotation speed of the first platform <NUM>.

The controller <NUM> may include one or more processors <NUM>, a memory device <NUM>, and an input device <NUM>. The processor(s) <NUM> may provide control signals to certain controllable devices and components (e.g., motors, actuators, brakes, or the like) associated with the first platform drive assemblies <NUM> and other relevant assemblies/systems. The processor(s) <NUM> may be configured to receive inputs via an input device <NUM> (e.g., from a ride operator; from riders; from a computing device) and to provide the control signals to the controllable devices and components in response to the inputs.

Further, the processor(s) <NUM> may receive a signal generated by a sensor in response to the detected event (e.g. one of the support beams <NUM> contacting or being within the threshold distance of the rail <NUM>) during a ride operation. The processor(s) <NUM> may respond to the received signals. For example, if the ride operation is near an end, the processor(s) <NUM> may determine and/or send an instruction to the control system <NUM> that the ongoing ride operation may proceed until reaching the end. In an embodiment, where multiple sensors are installed (e.g., on multiple support beams <NUM>), the processor(s) <NUM> may determine and/or instruct continuing or terminating the ride operation based on a number of support beams <NUM> in contact with or within the threshold distance of the rail <NUM>. For example, if the processor(s) <NUM> receives a signal from one sensor indicating a contacting event has been detected during a ride operation, the processor(s) <NUM> may determine and/or send an instruction to the controller <NUM> that the ride operation may proceed. However, when the processor(s) <NUM> receives signals from both sensors installed on the paired support beams <NUM> of one drive unit <NUM> or from multiple sensors installed on multiple support beams <NUM> of multiple drive units <NUM>, the processor(s) <NUM> may determine and/or send an instruction to the controller <NUM> that the ride operation should be terminated. In response, the controller <NUM> may instruct a suitable action, such as to maintain the ride operation, stop the ride operation, and/or provide a notification for repair (e.g., to a ride operator).

<FIG> is a cross-sectional perspective view of one of the second platform drive assemblies <NUM>, as described in <FIG>. For example, the portion of the second platform drive assembly <NUM> shown here may be from one of the second platform drive assemblies <NUM> described previously. Each of the second platform drive assemblies <NUM> may be used to drive a corresponding second platform <NUM> to rotate about a respective second rotational axis (e.g., the second rotational axis 56A).

During ride operations, each second platform <NUM>, a group of the multiple figures 16B positioned on the second platform <NUM>, and the second platform drive assembly <NUM> may rotate together in a circumferential direction (e.g., circumferential direction <NUM>). During this rotation, each figure 16B in the group of multiple figures 16B positioned on the second platform <NUM> may move up and down relative to the second platform <NUM> along a respective figure axis <NUM>. Meanwhile, each figure 16B in the group of multiple figures 16B may rotate about the respective figure axis <NUM>.

As illustrated, the second platform drive assembly <NUM> shown here may include a plate assembly <NUM> and one or more drive wheel assemblies <NUM>. The plate assembly <NUM> may provide a rotation base for the second platform <NUM> mounted on top of the plate assembly <NUM>. The drive wheel assembly <NUM> may provide the drive force for the plate assembly <NUM>.

The plate assembly <NUM> may include a fixed plate <NUM> (e.g., fixed to the radially-extending beam <NUM>), a rotatable plate <NUM> (e.g., rotatable relative to the fixed plate <NUM>), and a bearing plate <NUM> between the fixed plate <NUM> and the rotatable plate <NUM>. The fixed plate <NUM> may be positioned on top of the radially-extending beam <NUM>. Additionally, the fixed plate <NUM> may be connected to a corresponding first platform drive assembly <NUM> by one or more additional connection beams <NUM>. The bearing plate <NUM> is placed under the rotatable plate <NUM> to distribute the load (e.g., combined weight from the second platform <NUM> and the group of the multiple figures 16B positioned on the second platform <NUM>) and/or transfer concentrated compressive forces between the fixed plate <NUM> and the rotatable plate <NUM>. The rotatable plate <NUM> is used to drive the second platform <NUM> to rotate about a respective vertical axis (e.g., second rotational axis 56A) during ride operations.

Both the fixed plate <NUM> and the rotatable plate <NUM> may have radially-outer (e.g., donut-shaped, ring-shaped, annular) surfaces. In an embodiment, both the fixed plate <NUM> and the rotatable plate <NUM> may have hollow structural sections to provide a low-weight structure, thus increasing driving efficiency of the drive wheel assemblies <NUM> during ride operations.

In an embodiment, the fixed plate <NUM>, the rotatable plate <NUM>, and the bearing plate <NUM> may be concentric (e.g., centered about the second rotational axis 56A). The inner diameters of the fixed plate <NUM>, the rotatable plate <NUM>, and the bearing plate <NUM> may be same or similar to each other, while the outer diameters may be different. For example, the fixed plate <NUM> may have a larger outer diameter than the rotatable plate <NUM> and the bearing plate <NUM>. The bearing plate <NUM> may have a smaller outer diameter than the fixed plate <NUM> and the rotatable plate <NUM>.

The drive wheel assemblies <NUM> may include a drive wheel <NUM>, a wheel holder <NUM>, and a drive motor <NUM>. Driven by the drive motor <NUM>, the drive wheel <NUM> may be movable along the radially-outer surface of the fixed plate <NUM>. The wheel holder <NUM>, which may be placed between the drive wheel <NUM> and the drive motor <NUM>, may be used to hold the drive wheel <NUM> onto the radially-outer surface of the fixed plate <NUM>. The wheel holder <NUM> may have certain contact parts (e.g., extended from the main body of the wheel holder <NUM> toward the rotatable plate <NUM>) that may contact the radially-outer surface of the rotatable plate <NUM>. Therefore, rotation of the drive wheel <NUM> (e.g., about a rotational axis <NUM>) may drive the rotatable plate <NUM> to rotate about the second rotational axis 56A, accordingly driving the second platform <NUM> to rotate about the second rotational axis 56A during ride operations.

It should be appreciated that the wheel holder <NUM> may contact the fixed plate <NUM> and the drive wheel <NUM> may move along the radially-outer surface of the rotatable plate <NUM>. The drive motor <NUM> may be any type of electrical motor that generates the rotational force used to drive the drive wheel(s) <NUM> to rotate. Although not shown here, the drive wheel assemblies <NUM> may include other components, such as one or more brake units, one or more biasing members, one or more gearboxes, and the like.

Additionally, it should be appreciated that the operations of the second platform drive assemblies <NUM> may be coordinated and controlled by a controller <NUM> (e.g., electronic controller). The controller <NUM> may control and coordinate the operations of the plate assemblies <NUM> and drive wheel assemblies <NUM>. For example, the controller <NUM> may control one or more drive motors <NUM> and/or associated brakes to start or stop one or more rotations of the second platforms <NUM>. In an embodiment, the controller <NUM> may adjust speed settings of the drive motors <NUM> to control a rotational speed of the second platform <NUM>.

The controller <NUM> may include one or more processors <NUM>, a memory device <NUM>, and an input device <NUM>. The processor(s) <NUM> may provide control signals to certain controllable devices and components (e.g., motors, actuators, brakes,) associated with the second platform drive assemblies <NUM> and other relevant assemblies/systems. The processor(s) <NUM> may be configured to receive inputs via an input device <NUM> (e.g., from a ride operator; from a rider) and to provide the control signals to the controllable devices and components in response to the inputs. For example, during certain ride operations, one or more second platforms <NUM> may be reserved for special events (e.g. family rides) that allow adults to ride with children. Accordingly, certain figures 16B may be modified to have double-seat features. The operator may use the controller <NUM> directly or indirectly (e.g., through the controller <NUM> that may provide access to the controller <NUM> remotely) to adjust the operations of the reserved second platforms <NUM> based on characteristics of the figures 16B and/or preferences of the riders. For instance, the rotational speed of the reserved second platforms <NUM> may be adjusted lower or higher during a time window during ride operations based on the characteristics of the figures 16B and/or preferences of the riders.

The memory device <NUM> may include one or more tangible, non-transitory, computer-readable media that store instructions executable by the processor(s) <NUM>. The adjustable rotational speed of the reserved second platforms <NUM> may be stored in the memory device <NUM> so that the preferred operations related to the family ride events may be performed automatically via the processor(s) <NUM> with or without the operator's supervisions. The memory device <NUM> may include random access memory (RAM), read only memory (ROM), rewritable non-volatile memory such as flash memory, hard drives, optical discs, and/or the like. Additionally, the processor(s) <NUM> may include one or more general purpose microprocessors, one or more application specific processors (ASICs), one or more field programmable gate arrays (FPGAs), or any combination thereof.

Turning to <FIG>, a perspective view of one of the figure drive assemblies <NUM> is illustrated. As stated previously, each figure drive assembly <NUM> may be concealed inside the respective housing unit <NUM> that is located under the first platform <NUM> or the respective second platform <NUM>. Each housing unit <NUM> may be attached to a bottom side of the first platform <NUM> or the respective second platform <NUM>. Each pole <NUM> may extend from the connected housing unit <NUM> along the figure axis <NUM>, through a respective opening in either the first platform <NUM> or one of the second platforms <NUM>, to a corresponding figure <NUM>.

A support assembly <NUM> may be used to provide support for the pole <NUM> and to provide mounting points for a lift assembly <NUM> and a rotation assembly <NUM>. The lift assembly <NUM> may drive the pole <NUM> to move up and down along the figure axis <NUM> during ride operations. The rotation assembly <NUM> may drive the pole <NUM> to rotate about the figure axis <NUM> during ride operations. With the figure drive assembly <NUM> and the resulting increased operational flexibility of the carousel ride system <NUM>, the ride guests may have a more enjoyable riding experience.

The support assembly <NUM> may include a post <NUM> mounted on a base plate <NUM>. As shown, one or more ribs <NUM> may be installed (e.g., welded) between the lower portion of the post <NUM> and the base plate <NUM> to reinforce the joint between the post <NUM> and the base plate <NUM>, therefore increasing the stability of the pole <NUM> and the corresponding figure <NUM> attached to the pole <NUM> during ride operations. The post <NUM> may have a hollow structural section to provide a low-weight structure, thus reducing the weight attached to the first platform <NUM> and the second platform <NUM>.

The lift assembly <NUM> may include a lift motor <NUM> installed on a lift motor base <NUM>. The lift motor base <NUM> may be mounted on the base plate <NUM>. A threaded shaft <NUM> (e.g., ball screw) may be installed with one end rotatably coupled to the lift motor base <NUM>, and another end rotatably coupled to a shaft bracket <NUM> that is mounted on the post <NUM>. The threaded shaft <NUM> may be utilized in conjunction with bearings (e.g., ball bearings) to facilitate rotation of the threaded shaft <NUM>. The lift motor <NUM> may be any type of electrical motor that generates the rotational force used to drive the threaded shaft <NUM> to rotate. The lift motor base <NUM> may include gears (e.g., spur gears and/or other types of gears) that may transfer motion (e.g., rotations) from an output shaft of the lift motor <NUM> to the threaded shaft <NUM>. The threaded shaft <NUM> extend through a threaded opening in a mounting bracket <NUM>, and the rotation of the threaded shaft <NUM> may drive linear movement of the mounting bracket <NUM> (and the components, such as the pole <NUM>, supported on the mounting bracket <NUM>) along the figure axis <NUM>.

The threaded shaft <NUM> may thus be considered a linear actuator that translates rotational motion to linear motion with little friction. It should be appreciated that an additional and/or alternative driving mechanism may be utilized. For example, other types of linear actuators may be used to translate rotational motions to linear motions.

As shown, a pair of mounting brackets <NUM> and <NUM> are mounted on the support assembly <NUM>. At least one of the mounting brackets (e.g., mounting bracket <NUM>) may have the threaded opening to accept the threaded shaft <NUM>. The mounting bracket <NUM> may be coupled to a pair of guides <NUM>. Similarly, the mounting bracket <NUM> may be coupled to another pair of guides <NUM>. Both the pair of guides <NUM> and the pair of guides <NUM> may move freely along a pair of rails <NUM> that are mounted on the post <NUM>.

In addition to translational motions provided by the lift assembly <NUM>, rotational motions may be provided by the rotation assembly <NUM>. The rotation assembly <NUM> may include a rotation motor <NUM> installed on a rotation motor base <NUM>. The rotation motor base <NUM> may be coupled to the mounting bracket <NUM> and to a sleeve <NUM> (e.g., rod). The rotation motor <NUM>, the rotation motor base <NUM>, the mounting bracket <NUM>, the sleeve <NUM>, and/or the pole <NUM> may translate along the figure axis <NUM> via operation of the lift assembly <NUM>. Additionally, the sleeve <NUM> and the pole <NUM> coupled thereto may be driven to rotate about the figure axis <NUM> via operation of the rotation assembly <NUM>. The rotation motor <NUM> may be any type of electrical motor that generates the rotational force used to drive the sleeve <NUM> to rotate. The rotation motor base <NUM> may include gears (e.g., spur gears and/or other types of gears) that may transfer rotation from an output shaft of the rotation motor <NUM> to the sleeve <NUM>.

As the sleeve <NUM> is coupled to the pole <NUM>, motions of the sleeve <NUM>, including translational motions along the figure axis <NUM> and rotational motion about the figure axis <NUM>, may be transferred to motions of the pole <NUM>, which in turn may be transferred to motions of the figure <NUM> that is mounted on the pole <NUM>. Therefore, in the carousel ride system <NUM>, each figure <NUM> may raise, lower, and rotate independently during ride operations. It should be appreciated that the sleeve <NUM> and the pole <NUM> may be integrally formed with one another, or the rotation assembly <NUM> may be configured to drive the pole <NUM> without rotation of the sleeve <NUM>, for example.

Additionally, it should be appreciated that the operations of the figure drive assembly <NUM> may be coordinated and controlled by a controller <NUM> (e.g., electronic controller). The controller <NUM> may control and coordinate the operations of the lift assembly <NUM> and rotation assembly <NUM>. For example, the controller <NUM> may control the lift motor <NUM> to cause the corresponding figure <NUM> to start or stop moving up and down during ride operations. In an embodiment, the controller <NUM> may adjust speed settings of the rotation motor <NUM> to control rotational speeds and/or direction of the corresponding figure <NUM> during ride operations.

The controller <NUM> may include one or more processors <NUM> and a memory device <NUM>. The processor(s) <NUM> may provide control signals to certain controllable devices and components (e.g., motors, actuators, brakes, or the like) associated with the individual lift and rotate system <NUM> and other relevant assemblies/systems. The processor(s) <NUM> may be configured to receive inputs via an input device <NUM> (e.g., from a ride operator, from riders, from a computing device) and to provide the control signals to the controllable devices and components in response to the inputs. For example, certain figures <NUM> may be put offline for maintenance so that the individual lift and rotation may be disabled.

The memory device <NUM> may include one or more tangible, non-transitory, computer-readable media that store instructions executable by the processor(s) <NUM>. In the example of figure maintenance described above, the identification of figures <NUM> determined for maintenance may be stored in the memory device <NUM> so that these figures <NUM> may be disabled during ride operations before maintenance commences. The memory device <NUM> may include random access memory (RAM), read only memory (ROM), rewritable non-volatile memory such as flash memory, hard drives, optical discs, and/or the like. Additionally, the processor(s) <NUM> may include one or more general purpose microprocessors, one or more application specific processors (ASICs), one or more field programmable gate arrays (FPGAs), or any combination thereof.

<FIG> are cross-sectional side views of an embodiment of a central figure drive assembly <NUM> that may be used in a carousel ride system, such as the carousel ride system <NUM> of <FIG>. In <FIG>, the central figure drive assembly <NUM> is in a loading configuration <NUM> (e.g., lowered or first configuration). In <FIG>, the central figure drive assembly <NUM> is in a ride configuration <NUM> (e.g., raised or second configuration.

The central figure drive assembly <NUM> may include a center mast <NUM> that extends vertically upwardly from a floor <NUM> (e.g., ground). A figure <NUM> may be supported on a figure support assembly <NUM>, and the figure <NUM> and the figure support assembly <NUM> may be relative to the center mast <NUM> and the floor <NUM> along the vertical axis <NUM>. The figure support assembly <NUM> may include a figure support rod <NUM>, a bracket <NUM>, a first post <NUM>, and/or a second post <NUM>. The figure support assembly <NUM> may also include a gear assembly <NUM> and a crankshaft <NUM>. The central figure drive assembly <NUM> may further include a platform <NUM> (e.g., the first rotatable platform) and/or a roof <NUM>.

A motor <NUM> and/or a gear assembly <NUM> may be provided to drive the movement of the figure support assembly <NUM> and the figure <NUM> supported thereon. For example, the motor <NUM> and/or the gear assembly <NUM> may be positioned between and may contact a motor support rod <NUM> and a portion of the figure support assembly <NUM> to thereby drive the movement of the figure support assembly <NUM> and the figure <NUM> supported thereon. The bracket <NUM> and the gear assembly <NUM> may be coupled to the center mast <NUM> via respective splined interfaces <NUM>, which may facilitate the movement in the vertical direction <NUM> and block movement in the circumferential direction <NUM> relative to the center mast <NUM>.

In operation, the motor <NUM> may be controlled to adjust the central figure drive assembly <NUM> to the loading configuration <NUM> in which the figure <NUM> is positioned at a first distance above the platform <NUM> to enable a rider to board the figure <NUM>. Then, upon initiation of the ride operation, the motor <NUM> may be controlled to adjust the central figure drive assembly <NUM> to the ride configuration <NUM> in which the figure <NUM> is positioned at a second distance above the platform <NUM> that is greater than the first distance to provide the rider with a more exciting ride experience. Then, in the ride configuration <NUM>, the crankshaft <NUM> may be driven to rotate (e.g., via its own motor and/or the gear assembly <NUM>), as shown by an arrow <NUM>. The rotation of the crankshaft <NUM> may cause the figure <NUM> to move up and down relative to the platform <NUM>. In this way, the central figure drive assembly <NUM> may enable the figure <NUM> to move through relatively large distances (e.g., more than <NUM> meter) relative to the platform <NUM> between the loading configuration <NUM> and the ride configuration <NUM> to provide for easy loading and to maintain a high vertical position throughout the ride operation, but also to move repeatedly through relatively small distances (e.g., less than <NUM> meter) relative to the platform <NUM> to provide an up and down motion (e.g., undulating motion) while the figure <NUM> is at the high vertical position during the ride operation. Furthermore, the center mast <NUM> may rotate in the circumferential direction <NUM> relative to the floor <NUM>, which may drive rotation of the figure <NUM> and the figure support assembly <NUM> in the circumferential direction <NUM> relative to the floor <NUM> (e.g., via the splined interfaces <NUM>). In this way, the rider may travel up and down along the vertical axis <NUM> and around in the circumferential direction <NUM> during the ride operation. It should be appreciated that multiple figures <NUM> and their respective figure support assemblies <NUM> may be coupled to the center mast <NUM> at staggered positions (e.g., about a circumference of the center mast <NUM> and/or along the vertical axis <NUM>). In such cases, the multiple figures <NUM> may move from the loading configuration <NUM> to the ride configuration <NUM> together (e.g., at the beginning of the ride operation) and then may move via their respective crankshafts <NUM> throughout the ride operation. However, different operations and sequences of operations are envisioned. For example, certain figures <NUM> may remain in the loading configuration <NUM> during the ride operation, such as in based on a rider selection or characteristics of the rider (e.g., a child).

It should be appreciated that the central figure drive assembly <NUM> may be utilized to drive figures in any of a variety of carousel ride systems. For example, the central figure drive assembly <NUM> may be utilized to drive the figures 16A of the carousel ride system <NUM> of <FIG>. In such cases, the center mast <NUM> may be positioned along the first rotational axis <NUM> of the first rotatable platform <NUM> shown in <FIG>. Some or all of the figures 16A of <FIG> may be coupled to the center mast <NUM> (e.g., at staggered positions about the circumference of the center mast <NUM>) via their own figure support assembly <NUM>, and the figures 16A of <FIG> may rotate with the first rotatable platform <NUM> of <FIG> (e.g., via the splined interface <NUM>) and may move up and down along the vertical axis <NUM> in the manner disclosed herein. It should be appreciated that the central figure drive assembly <NUM> may be utilized to drive the figures 16B of the carousel ride system <NUM> of <FIG>. In such cases, the center mast <NUM> may be positioned along the second rotational axis <NUM> of the second rotatable platform <NUM> shown in <FIG>. Some or all of the figures 16B of <FIG> may be coupled to (e.g., at staggered positions) the center mast <NUM> via their own figure support assembly <NUM>, and the figures 16B of <FIG> may rotate with the first rotatable platform <NUM> of <FIG> (e.g., via the splined interface <NUM>) and may move up and down along the vertical axis <NUM> in the manner disclosed herein.

While only certain features of present embodiments have been illustrated and described herein, many modifications and changes will occur to those skilled in the art.
