2. Description of the Relevant Art
The 80's decade has witnessed phenomenal growth in the participatory family water recreation facility, i.e., the waterpark, and in water oriented ride attractions in the traditional themed amusement parks. The main current genre of water ride attractions, e.g., waterslides, river rapid rides, and log flumes, and others, require participants to walk or be mechanically lifted to a high point, wherein, gravity enables water, participant(s), and riding vehicle (if appropriate) to slide down a chute or incline to a lower elevation splash pool, whereafter the cycle repeats.
Generally speaking, the traditional downhill water rides are short in duration (normally measured in seconds of ride time) and have limited throughput capacity. The combination of these two factors quickly leads to a situation in which patrons of the parks typically have long queue line waits of up to two or three hours for a ride that, although exciting, lasts only a few seconds. Additional problems like hot and sunny weather, wet patrons, and other difficulties combine to create a very poor overall customer feeling of satisfaction or perceived entertainment value in the waterpark experience. Poor entertainment value in waterparks as well as other amusement parks is rated as the biggest problem of the waterpark industry and is substantially contributing to the failure of many waterparks and threatens the entire industry.
Waterparks also suffer intermittent closures due to inclement weather. Depending on the geographic location of a waterpark, the waterpark may be open less than half of the year. Waterparks may be closed due to uncomfortably low temperatures associated with winter. Waterparks may be closed due to inclement weather such as rain, wind storms, and/or any other type of weather conditions which might limit participant enjoyment and/or participant safety. Severely limiting the number of days a waterpark may be open naturally limits the profitability of that waterpark.
The phenomenal growth of waterparks in the past few decades has witnessed an evolution in water-based attractions. In the '70s and early '80s, these water attractions took the form of slides from which a participant started at an upper pool and slid by way of gravity passage down a serpentine slide upon recycled water to a lower landing pool. U.S. Pat. No. 3,923,301 to Myers discloses such a slide dug into the side of a hill. U.S. Pat. Nos. 4,198,043 to Timbes and 4,196,900 to Becker et al. disclose such slides supported on a structure. Each of these slides only allowed essentially one-dimensional movement from the upper pool, down the slide to the lower pool. Consequently, the path taken down the slide always remained the same thus limiting the sense of novelty and the unexpected for the participant after multiple uses.
Cognizant of this limitation in traditional water slides, new water attractions were developed which inserted a little more of the element of chance during the ride. One such attraction has up to twelve people seated within a circular floating ring being propelled down a flume comprising a series of man-made rapids, water falls and timed water spouts. As the floating ring moves down the path of the water attraction, contact with the sides of the flume cause the ring to rotate thus moving certain people in closer proximity to the “down-river” side of the rapids, the water falls and the spouts. Those people who were closest to such features of the water ride tended to get the most wet. Since such movement was determined mostly by chance, each participant had an equal chance of getting drenched throughout the ride by any one of the many water ride features.
This later type of ride, though an improvement over the traditional water slide, was still essentially a one-dimensional travel from an upper start area down to a lower start area where all features came into play. Furthermore, each of these features were either continuously active (such as the water fall) or automatically activated by the proximity of the floating ring to the feature.
The popularity of these types of rides has resulted in very long lines at such waterparks. Observers, such as those waiting in line for the water ride, could not interact (except verbally) with those participants on the ride. Consequently, the lasting memory at such parks may not be about the rides at the park, but the long lines and waiting required to use the rides.
For the reasons stated above and more, it is desirable to create a natural and exciting amusement ride system to transport participants between rides as well as between parks that will interconnect many of the presently diverse and stand-alone waterpark rides. An amusement ride system and method are described. In some embodiments, an amusement ride system may be generally related to water amusement attractions and rides. Further, the disclosure generally relates to water-powered rides and to a system and method in which participants may be more involved in a water attraction.
In some embodiments, a portion of a path system may include special effects. The special effects may include visual effects (e.g., lighting displays). Path systems may include a conduit through which a participant may be conveyed. A portion of the conduit may be enclosed and pressurized fluids may assist conveying the participant the enclosed conduit. The path system may inhibit the participant from exiting a portion of the path system.
An amusement ride system may include an elevation system to convey a participant from a first elevation to a second elevation. The elevation system may include, for example, a fluid jet, a conveyor belt system, an uphill water slide, a wind tunnel or a vertical jet to elevate the participant to a predetermined height. Fluid jets may fall under a broad category of elevation systems referred to as fluid assisted elevation systems.
In some embodiments, an amusement ride system may include a floating queue line. The floating queue line may be coupled to a portion of a path system. The floating queue line may include a channel. The channel may hold water at a depth sufficient to allow a participant to float within the channel. The floating queue line may be coupled to a water ride such that a participant remains in the water while being transferred from the channel along the floating queue line to the water ride.
A portion of a water path system may include a substantially horizontal channel segment including a first portion and a second portion. The portion may include a water inlet positioned at the first portion and a water outlet positioned at the second portion. Water may be transferred into the channel at the first portion and transferred out of the channel at the second portion in sufficient quantities to create a hydraulic gradient between the first portion and the second portion.
A portion of a path system may include a substantially angled channel segment including a high elevation end and a low elevation end. The angled channel segment may function such that a participant moves in a direction from the upper elevation end toward the lower elevation end. The path system may include a water inlet at the high elevation end. A predetermined amount of water may be transferred into the angled channel segment at the high elevation end such that friction between a participant and the angled channel segment is reduced. A flowing body of water may have a depth sufficient to allow a participant to float within the channel during use
In some embodiments, a path system may include a plurality of fluid jets spaced apart. The fluid jets may be positioned along the path system at predetermined locations. The fluid jets may be oriented tangentially with respect to the path system surface so as to contact a participant as a participant passes by each of the locations. Each of the fluid jets may produce a fluid stream having a predetermined velocity that is selectively greater, less than, or the same as the velocity of the participant at each of the fluid jet locations.
A portion of a path system may be coupled to a walkway. A segment of the portion of the path system is at substantially the same height as a portion of the walkway such that a participant walks from the walkway into the water within the path system.
A portion of a path system may be coupled to a stairway. The stairway may function such that a participant walks along the stairway into the water within the path system.
A path system may include a docking station coupled to at least a portion of the path system. The docking station may receive and inhibit movement of inflatable vehicles to allow participants to exit or enter the inflatable vehicles.
An amusement ride system may include at least one overflow pool coupled to a path system. The overflow pool may collect water overflowing from the path system.
In some embodiments, an amusement ride may form a portion of a transportation system. The transportation system would itself be a main attraction with water and situational effects while incorporating into itself other specialized or traditional water rides and events.

The first source of water and/or the second source of water may include a portion substantially adjacent the belt, wherein the portion of the first and/or second source of water comprises a depth of water which allows a participant to more easily enter a floatation device.
Depending on a water amusement parks geographic location, the waterpark may only be open for less than half of the year due to inclement weather (e.g., cold weather, rain, etc.). What is needed is a way to enclose portions or substantially all of the waterpark when weather threatens to shut down the park. However, it would be beneficial to have some type of enclosure that may be at least partially removed or retracted to open up at least a portion of the waterpark to the environment during good weather.
Positionable screens may be used to substantially enclose a portion of a waterpark during inclement weather. A multitude of positionable screens may be retractable/extendable within one another. The screens may also serve other functions in addition to protecting participants from uncomfortable weather conditions. The screens may be used to trap and recirculate heat lost from, for example, the water enclosed within the screens. The positioning of the screens may be automated, manual, or a combination of both. The screens may be formed from materials that allow most of the visible light spectrum through while inhibiting transmission of potentially harmful radiation.

While the invention is susceptible to various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawing and will herein be described in detail. It should be understood, however, that the drawings and detailed description thereto are not intended to limit the invention to the particular form disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the present invention as defined by the appended claims.
Amusement rides may include so called “water” amusement rides. Water amusement rides typically include water as an effect at least in some portion of the amusement ride. The amusement ride may include multiple different elevation points coupled to one another with some type of path system. In some embodiments, a path system may include, for example, conduits, channels, portions of natural rivers, portions of natural bodies of water, rails, and/or tracks. Path systems may include paths that split into two or more paths. Paths that have split may subsequently rejoin at a later point in the path system. A path system may include, for example, a conduit or channel. Channels typically include a water element and may include water deep enough for inflatable vehicle to float along the channel. The channel may include sides that are high enough to inhibit water within the channels from inadvertently spilling over the sides. The channel may include barriers or sides that are high enough to inhibit a participant from exiting over the sides prematurely and/or in an uncontrolled manner.
In some embodiments, a path system may include a conduit (e.g., a tube). The conduit may not include water or any type of water element. The conduit as the term implies is a substantially enclosed path system which may inhibit a participant from exiting over the sides prematurely and/or in an uncontrolled manner. “Fully enclosed” is not necessarily limited to a seamless and/or continuous sheet forming the conduit. Portions of the conduit may be formed out of a rigid material in a cage or net like formation. A perforated conduit may allow participants greater visibility and/or enjoyment during an amusement ride. The conduit may be formed from substantially transparent materials. In some embodiments, portions of the conduit may be formed from substantially transparent materials. Forming portions of a conduit from transparent materials may allow a participant greater visibility (and consequently greater enjoyment) during an amusement ride.
In some embodiments, substantially parallel bars coupled together may form a conduit. In some embodiments, mixtures of different materials and methods for forming conduits may be employed.
An embodiment of a path system may be formed from at least two materials of different transparencies. The upper portion of a path system may be formed from a substantially transparent material. The lower portion of a path system may be formed of a substantially opaque material. Advantages of such a path system may include reducing construction costs. For example various opaque construction materials may be less expensive than comparable translucent materials. The translucent portion of the path system may be less expensive to produce in part due to the fact that it is not necessary to produce the top portion to the same weight bearing capacities of the lower portion of the path system.
These restraining members may also be referred to as barriers. Barriers may generally function to inhibit participants from entering or exiting a particular area. Barriers may be associated with any portion of a water amusement park and may come in a variety of forms. In some embodiments, barriers may be positioned along the sides of water amusement park features. Barriers may be positioned along the sides of water channels inhibiting participants from exiting/entering the water channel prematurely and encourage participants to use predetermined access points. In some embodiments, barriers may be positioned over portions of a water amusement park. Barriers positioned along the sides and over portions of water amusement park may function together to substantially enclose a portion of a water amusement park except for designated access points.
Barriers may be associated with portions of a water amusement park including, but not limited to, water channels, downhill water slides, uphill water slides, pool, and conveyor belts. Barriers may be constructed of rigid materials (e.g., plastics such as polycarbonates). Barrier materials may be substantially transparent (e.g., polycarbonate) and/or allow participants a virtually unimpeded view through the barriers. In some embodiments, barriers may comprise substantially flexible materials (e.g., flexible polymeric fencing materials) or comprise rigid materials fashioned in a substantially flexible manner (e.g., chain link fencing).
In some embodiments, barriers may be designed to be quickly and/or easily assembled and disassembled. Portions of barriers may be designed to opened such that access to the portion of the water amusement park the barrier is inhibiting may be accessed during times of emergency or need (e.g., cleaning, mechanical failure, injury to a participant). Portions of a barrier may be designed to be drawn aside like a curtain for flexible materials or like a sliding door for less flexible materials.
In some embodiments, barriers may server multiple functions. Barriers may do more than just inhibit access to particular portions of a water amusement park. Barriers may be designed to provide shade to participants when situated within a portion associated with the barriers. In some embodiments, barriers may act as solar panels or work as part of a heat sink. Barriers may function to inhibit participants from accessing and/or viewing a portion of a water amusement park. In some embodiments, barriers may function to serve as a structural support for other water and/or entertainment features (e.g., light shows and/or displays).
In some embodiments, a barrier may be positioned along the sides and/or above a portion of a water amusement park. One or more of the barriers may be positioned adjacent one or more sides of a conveyor belt. At least a portion of one or more of the barriers may be configured such that the contours of the portion substantially complement the contours of a portion of a waterpark.
In some embodiments, portions of a waterpark may constructed on based on a foundation formed from a support structure 126.
In some embodiments, portions of a waterpark may include a spatial adjustment mechanism. Spatial adjustment mechanisms may include any mechanism capable of functioning to spatially adjust a first portion of a waterpark relative to a second portion of a waterpark. Spatial adjustment mechanisms may include a cam system. Spatial adjustment mechanisms may include a system of two or more telescoping support “legs”. Advantages of a spatial adjustment mechanism may include facilitating assembly of modular portions of a waterpark.
In some embodiments, a spatial adjustment mechanism may function to spatially adjust a first portion of a waterpark relative to a second portion of a waterpark such that an end of the first portion is substantially aligned with an end of the second portion.
A cam adjustment system may function by rotation of a pivot point coupled to a support structure 126. The pivot point may include an elongated member 108. The pivot point may be coupled to the support structure via an elliptical or elongated member such that as the pivot point is rotated the support structure and anything coupled to it move in a relative direction.
Spatial adjustment mechanisms may include systems which function to adjust a first portion of a waterpark relative to a second portion in any dimension deemed necessary under the circumstances. Embodiments described have concentrated on vertical spatial adjustment, however, this should not be viewed as a limiting example. Systems for spatially adjusting a portion of a waterpark my adjust the portion in a horizontal plane. Systems may function to adjust a portion of a waterpark spatially in more than one dimension.
In some embodiments, a conveyor belt system may include one or more support elements coupled to the support structure. Support elements may be configured to support and align a belt as the belt moves between the support structure and the support elements. Support elements may comprise a curved surface such that movement of the belt over the curved surface of the support element is facilitated. Traditionally support elements used in association with conveyor belts may include moving parts or elements. For example a roller or a system of rollers (e.g., a belt of rollers) may be used to support a from a conveyor belt as the belt moves in a continuous circle. Rollers have been used to provide support for a flexible conveyor belt.
In some embodiments, a support element may have no moving parts. In some embodiments, a support element may have substantially no moving parts. Advantages of no moving parts in the support elements may include less occurrence of malfunction and need for repair especially in the harsh conditions associated with waterparks.
Almost all waterpark rides require substantial waiting periods in a queue line due to the large number of participants at the park. This waiting period is typically incorporated into the walk from the bottom of the ride back to the top, and can measure hours in length, while the ride itself lasts a few short minutes, if not less than a minute. A series of corrals are typically used to form a meandering line of participants that extends from the starting point of the ride toward the exit point of the ride. Besides the negative and time-consuming experience of waiting in line, the guests are usually wet, exposed to varying amounts of sun and shade, and are not able to stay physically active, all of which contribute to physical discomfort for the guest and lowered guest satisfaction. Additionally, these queue lines are difficult if not impossible for disabled guests to negotiate.
The concept of a continuous water ride was developed to address the problems and issues stated above associated with water amusement parks. Continuous water rides may assist in eliminating and/or reducing many long queue lines. Continuous water rides may eliminate and/or reduce participants having to walk back up to an entry point of a water ride. Continuous water rides may also allow the physically handicapped or physically challenged to take advantage of water amusement parks. Before that may have been difficult if not impossible due to many flights of stairs typically associated with water amusement parks.
In some embodiments, continuous water rides may include a system of individual water rides connected together. The system may include two or more water rides connected together. Amusement rides described herein may include downhill water slides, uphill water slides, single tube slides, multiple participant tube slides, space bowls, sidewinders, interactive water slides, water rides with falling water, themed water slides, dark water rides, and/or accelerator sections in water slides. Connections may reduce long queue lines normally associated with individual water rides. Connections may allow participants to remain in the water and/or in an inflatable vehicle during transportation from a first portion of the continuous water ride to a second portion of the continuous water ride.
In some embodiments, an exit point of a first water ride may be connected to an entry point of a second water ride forming at least a portion of a continuous water ride. The exit point of the first water ride and the entry point of the second water ride may be at different elevation levels. An elevation system may be used to connect the exit point of the first water ride and the entry point of the second water ride. In some embodiments, an entry point of a second water ride may have a higher elevation than an exit point of a first water ride coupled to the entry point of the second water ride.
In some embodiments, elevation systems may include any system capable of transporting one or more participants from a first point at one elevation level to a second point at a different elevation level. Elevation systems may include a conveyor belt system. Elevation systems may include a water lock system. Elevation systems may include an uphill water slide, a spiral transport system, and/or a water wheel.
In some embodiments, bodies of water 122 may include multiple elevation systems 124 and multiple water rides connecting each other. In some embodiments, floating queue lines and/or channels may couple water rides and elevation systems. Floating queue lines may help control the flow of participants more efficiently than without using floating queue lines.
In some embodiments, elevation systems may include a conveyor belt system. Conveyor belt systems may be more fully described in U.S. patent application Ser. No. 09/952,036 (Publication No. US-2002-0082097-A1), herein incorporated by reference. This system may include a conveyor belt system positioned to allow participants to naturally float up or swim up onto the conveyor and be carried up and deposited at a higher level.
The conveyor belt system may also be used to take participants out of the water flow at stations requiring entry and/or exit from the amusement ride. Participants float to and are carried up on a moving conveyor. Participants may be transported into the amusement ride at a desired location and velocity. The conveyor may extend below the surface of the water so as to more easily allow participants to naturally float or swim up onto the conveyor. Extending the conveyor below the surface of the water may allow for a smoother entry into the water when exiting the conveyor belt. Typically the conveyor belt takes participants from a lower elevation to a higher elevation, however it may be important to first transport the participants to an elevation higher than the elevation of their final destination. Upon reaching this apex the participants then may be transported down to the elevation of their final destination on a water slide, rollers, or on a continuation of the original conveyor that transported them to the apex. This serves the purpose of using gravity to push the participant off and away from the belt, slide, or rollers into a second water ride of the continuous water ride and/or a floating queue. The endpoint of a conveyor may be near a first end of a horizontal hydraulic head channel wherein input water is introduced through a first conduit. This current of flowing may move the participants away from the conveyor endpoint in a quick and orderly fashion so as not to cause increase in participant density at the conveyor endpoint. Further, moving the participants quickly away from the conveyor endpoint may act as a safety feature reducing the risk of participants becoming entangled in any part of the conveyor belt or its mechanisms. A deflector plate may also extend from one or more ends of the conveyor and may extend to the bottom of the channel. When the deflector plate extends at an angle away from the conveyor it may help to guide the participants up onto the conveyor belt as well as inhibit access to the rotating rollers underneath the conveyor. These conveyors may be designed to lift participants from one level to a higher one, or may be designed to lift participants out of the water, onto a horizontal moving platform.
In some embodiments, a belt may include a series of interlocking plates or pieces. A belt so constructed may be more durable. Examples of such a belt may be purchased commercially from Intralox, L.L.C.
The conveyor belt speed may also be adjusted in accordance with several variables. The belt speed may be adjusted depending on the participant density; for example, the speed may be increased when participant density is high to reduce participant waiting time. The speed of the belt may be varied to match the velocity of the water, reducing changes in velocity experienced by the participant moving from one medium to another (for example from a current of water to a conveyor belt). Conveyor belt speed may be adjusted so participants are discharged at predetermined intervals, which may be important where participants are launched from a conveyor to a water ride that requires safety intervals between the participants.
Several safety concerns should be addressed in connection with the conveyor system. The actual belt of the system should be made of a material and designed to provide good traction to participants without proving uncomfortable to the participants touch. Detection devices or sensors for safety purposes may also be installed at various points along the conveyor belt system. These detection devices may be variously designed to determine if any participant on the conveyor violating safety parameters. Gates may also be installed at the top or bottom of a conveyor, arranged mechanically or with sensors wherein the conveyor stops when the participant collides with the gate so there is no danger of the participant being caught in and pulled under the conveyor. Runners may cover the outside edges of the conveyor belt covering the space between the conveyor and the outside wall of the conveyor so that no part of a participant may be caught in this space. All hardware (electrical, mechanical, and otherwise) should be able to withstand exposure to water, sunlight, and various chemicals associated with water treatment (including chlorine or fluorine) as well as common chemicals associated with the participants themselves (such as the various components making up sunscreen or cosmetics).
In some embodiments, a conveyor belt system may include restraining devices and/or gripping devices. Restraining devices may be used to inhibit participants from moving while on the conveyor belt (other than the movement associated with the movement of the conveyor belt itself when activated).
Various sensors may also be installed along the conveyor belt system to monitor the number of people using the system in addition to their density at various points along the system. Sensors may also monitor the actual conveyor belt system itself for breakdowns or other problems. Problems include, but are not limited to, the conveyor belt not moving when it should be or sections broken or in need of repair in the belt itself. All of this information may be transferred to various central or local control stations where it may be monitored so adjustments may be made to improve efficiency of transportation of the participants. Some or all of these adjustments may be automated and controlled by a programmable logic control system.
Various embodiments of the conveyor lift station include widths allowing only one or several participants side by side to ride on the conveyor according to ride and capacity requirements. The conveyor may also include entry and exit lanes in the incoming and outgoing stream so as to better position participants onto the conveyor belt and into the outgoing stream.

In some embodiments, a gate mechanism may include a positionable arm. The positionable arm may be coupled to a dam or gate. The gate may be buoyant and function to hinder the progress of participants. The positionable arm may function to position the gate in an upward hindering position as depicted in
The gate mechanism may function such that few or no pinch points are accessible to a participant. The gate mechanism may be driven by outboard actuators (e.g., hydraulic or pneumatic). The gate mechanism may include a pivot shaft, actuators, and local drive unit. The gate mechanism may include sensors. Some of the sensors may communicate the position of the gate to a programmable controller. Some of the sensors may detect when participants approach the gate. Some of the sensors may detect when participants have safely cleared the gate. Sub-framework of the gate may be mounted directly to the path system flooring (e.g., concrete).
In some embodiments, a gate mechanism may include a cam-like structure. One end of the cam-like structure may be coupled to a pivot point which rotates a gate mechanism into position to inhibit participants from accessing and end of a conveyor belt.
In some embodiments, gate mechanisms may be used to direct participants toward one or more paths when there exists two or more alternative path choices built into a water amusement park ride system. The gate mechanism may be coupled to a control system. The control system and/or gate mechanism may be coupled to sensors. The control system may be at least partially automated.
In some embodiments, participants may signal which path option they prefer and a gate mechanism may comply appropriately with the participant's choice. For example, a participant may signal manually (e.g., vocally or using hand signals) which path option the participant prefers. Using motion detectors and/or voice recognition software may allow a control system to automatically position a gate mechanism such that a participant enters the desired path option. In some embodiments, a gate mechanism may be manually controlled by an operator. In some embodiments, a participant may use a personal electronic signally device to indicate which path option they prefer. For example a participant identifier may be used as described in U.S. patent application Ser. No. 10/693,654 entitled “CONTINUOUS WATER RIDE,” herein incorporated by reference.
In some embodiments, a gate mechanism may function to regulate the flow of participants between a multi-path option such that participants are distributed appropriately to maintain a maximum participant flow rate reducing participant waiting times. Appropriately distributing participants between path options of a water amusement ride and/or elevation system may include substantially evenly distributing participants between path options. Appropriately distributing participants between path options of a water amusement ride and/or elevation system may include distributing participants between path options based on each path's particular participant flow capacity.
One skilled in the art may use and/or modify common methods and devices to act as or accomplish similar ends of the gate mechanism (e.g., diverting participants between path options and/or controlling the flow of participants through a particular section of a water amusement ride and/or system).
A system of rollers may facilitate transfer of water amusement park participants onto and/or off of a portion of a water amusement park (e.g., conveyor belt, water channel or slide). In some embodiments, a system of rollers may ease the transition for participants onto and/or off of a conveyor belt. A system of rollers may include a plurality of rollers coupled together such that the rollers freely rotate about a central axis. In some embodiments, a system of rollers may include a plurality of rollers coupled together such that the rollers rotate about a central axis in a predetermined direction.
Rollers may be formed from materials which are resistant to conditions typically associated with a water amusement park. Rollers may be formed from materials with a low coefficient of friction to assist participants in transferring from different portions of a water amusement park. In some embodiment, roller may comprise materials which provide at least some give such that rollers are not uncomfortable for participants to traverse. In some embodiments, a system of rollers may function to have a certain amount of “give” built into them while still functioning to transfer participants. Rows of rollers may be linked such that there is a predetermined amount of flexibility between the rows of rollers such that the system of rollers as a whole flexes at least slightly. Slight flexing of the system of rollers may reduce the occurrence and severity of potential injuries associated with participants using the system of rollers to transfer from one portion of a waterpark to another portion of a waterpark, if for example the participant is traveling at a high rate of speed when the participant transfers to the system of rollers.
In some embodiments, a system of rollers may include a plurality of a series of individual rollers coupled together with an elongated member. In some embodiments, a system of roller may include a plurality of single rollers with an elongated member positioned through the roller. The elongated member upon which rollers rotate about may be formed from substantially rigid and/or substantially flexible materials.
In some embodiments, a launch conveyor may function as a transition between portions of a waterpark. A launch conveyor may be modular, facilitating insertion of the launch conveyor into portions of a waterpark. In certain embodiments, a launch conveyor may include a relatively short conveyor belt which is used to launch a participant to provide the participant with extra momentum before entering a portion of a water ride. A launch conveyor may be inserted in between a floating queue line and/or a downhill water slide. A launch conveyor may assist in controlling a participant flow rate.
In some embodiments, a launch conveyor may include a mechanism for adjusting and angle of ascent/descent of the conveyor. Adjusting the angle of ascent/descent may allow a launch conveyor to assist launching participants in a variety of ways including uphill, downhill, and horizontally.
In some embodiments, a launch conveyor may include a pump to assist in recirculating water such that there is not a build up of water at any point in a waterpark system.
In some embodiments, floating queue system 160 may include fluid jets. Floating queue system 160 may be designed as depicted in
Fluid jets within a floating queue system may assist in controlling the flow of participants onto a conveyor system and/or amusement park ride. Control systems may be coupled to the fluid jets to control the velocity of fluids exiting the jets to control the flow of participants onto a conveyor system and/or amusement park ride. In some embodiments, control systems may be at least partially automated. For example, control systems may include sensors coupled to the control system. Sensors may assist the control system in keeping track of a participant flow rate through a floating queue system such that a control system may adjust the participant flow rate accordingly. The control system may be coupled to sensors at least in the immediate vicinity of the park preceding and following the floating queue. In some embodiments, a floating queue system may assist in controlling the flow of participants off a conveyor system and/or amusement park ride.
In some embodiments, one or more fluid jets may be designed to produce a fluid stream having a predetermined velocity which is selectively greater, less than, or the same as a velocity of a participant at each of the fluid jet locations. At least some of the fluid jets may be positioned along a portion of the first source of water and/or a portion of the second source of water substantially adjacent to a portion of the belt. The fluid jets may be oriented tangentially with respect to the surface of the source of water so as to contact a participant and/or participant vehicle as a participant and/or participant vehicle passes by each of the locations.
In some embodiments, an amusement park system may include portions of a body of water (e.g., channels, pools, etc.) wherein the portions are shallower than the rest of the body of water. Shallower portions of a body of water may allow participants to more easily enter the amusement park system at this point. Shallower portions may allow a participant to more easily enter a water amusement ride and/or more easily mount/access a vehicle (e.g., an inflatable vehicle such as an inner tube). Shallower portions of a body of water may also be referred to as participant/vehicle access or entrance points. These shallower portions may be shallow enough to facilitate participants entrance into a ride/vehicle while still allowing the participant/vehicle to float. In some embodiments, shallower portions of a body of water may range from 1 to 4 feet in depth. In some embodiments, shallower portions of a body of water may range from 1 to 3 feet in depth. In some embodiments, shallower portions of a body of water may range from 1 to 2 feet in depth. In some embodiments, shallower portions of a body of water may range from 2 to 3 feet in depth.
In some embodiments, shallower portions of a body of water may be positioned adjacent a beginning point and/or end point of an elevation system (e.g., a conveyor belt elevation system). Shallower portions may be positioned in conjunction with or instead of floating queue system 160 as depicted in
In some embodiments, shallower portions of a body of water may be positioned before/adjacent a beginning point of a conveyor belt elevation system. The shallower portion may be used in combination with means for conveying water from a beginning of a conveyor belt elevation system to the end of the conveyor belt elevation system, described more fully in U.S. patent application Ser. No. 09/952,036 (Publication No. US-2002-0082097-A1). Water conveyed from a beginning point of a conveyor belt elevation system to an end point of a conveyor belt elevation system may be used to create a hydraulic gradient to assist in pushing a participant onto the conveyor belt and/or assist in pulling a participant off of the conveyor belt. The hydraulic gradient used in such a manner may assist in regulating the flow of participants through a conveyor belt elevation system as well as any water amusement park system to which the conveyor belt elevation system is a part of.
In some embodiments, path 116a and/or path 116b may include a queue line which funnels participants in a controlled manner to conveyor belt elevation system 124. Using two or more queue lines to funnel participants to an elevation system (especially an elevation system which may handle several participants at a time (e.g., wide enough to handle two participants next to each other)) may increase the loading efficiency of an amusement ride.
In some embodiments, an elevation system may include a water lock system. These systems may be used to increase elevation and/or decrease elevation. In certain embodiments, an exit point of a first water ride of a continuous water ride may have an elevation below an entry point of a second water ride of the continuous water ride. In some embodiments, the water lock system includes a chamber for holding water coupled to the exit point of the first water ride and the entry point of the second water ride. A chamber is herein defined as an at least partially enclosed space. The chamber includes at least one outer wall, or a series of outer walls that together define the outer perimeter of the chamber. The chamber may also be at least partially defined by natural features such as the side of a hill or mountain. The walls may be substantially watertight. The outer wall of the chamber, in certain embodiments, extends below an upper surface of the first water ride and above the upper surface of the second water ride. The chamber may have a shape that resembles a figure selected from the group consisting of a square, a rectangle, a circle, a star, a regular polyhedron, a trapezoid, an ellipse, a U-shape, an L-shape, a Y-shape or a figure eight, when seen from an overhead view.
A first movable member may be formed in the outer wall of the chamber. The first movable member may be positioned to allow participants and water to move between the exit point of the first water ride and the chamber when the first movable member is open during use. A second movable member may be formed in the wall of the chamber. The second movable member may be positioned to allow participants and water to move between the entry point of the second water ride and the chamber when the second movable member is open during use. The second movable member may be formed in the wall at an elevation that differs from that of the first movable member.
In certain embodiments, the first and second movable members may be configured to swing away from the chamber wall when moving from a closed position to an open position during use. In certain embodiments, the first and second movable members may be configured to move vertically into a portion of the wall when moving from a closed position to an open position. In certain embodiments, the first and second movable members may be configured to move horizontally along a portion of the wall when moving from a closed position to an open position.
A bottom member may also be positioned within the chamber. The bottom member may be configured to float below the upper surface of water within the chamber during use. The bottom member may be configured to rise when the water in the chamber rises during use. In certain embodiments, the bottom member is substantially water permeable such that water in the chamber moves freely through the bottom member as the bottom member is moved within the chamber during use. The bottom member may be configured to remain at a substantially constant distance from the upper surface of the water in the chamber during use. The bottom member may include a wall extending from the bottom member to a position above the upper surface of the water. The wall may be configured to prevent participants from moving to a position below the bottom member. A floatation member may be positioned upon the wall at a location proximate the upper surface of the water. A ratcheted locking system may couple the bottom member to the inner surface of the chamber wall. The ratcheted locking system may be configured to inhibit the bottom member from sinking when water is suddenly released from the chamber. The ratcheted locking system may also include a motor to allow the bottom member to be moved vertically within the chamber. There may be one or more bottom members positioned within a single chamber. The bottom member may incorporate fluid jets to direct and/or propel participants in or out of the chamber.
The lock system may also include a substantially vertical first ladder coupled to the wall of the bottom member and a substantially vertical second ladder coupled to a wall of the chamber. The first and second ladders, in certain embodiments, are positioned such that the ladders remain substantially aligned as the bottom member moves vertically within the chamber. The second ladder may extend to the top of the outer wall of the chamber. The ladders may allow participants to exit from the chamber if the lock system is not working properly.
In certain embodiments, water may be transferred into and out of the water lock system via the movable members formed within the chamber wall. Opening of the movable members may allow water to flow into the chamber from the second water ride or out of the chamber into the first water ride.
The lock system may also include a controller for operating the system. The automatic controller may be a computer, programmable logic controller, or any other control device. The controller may be coupled to the first movable member, the second movable member, and the first water control system. The controller may allow manual, semi-automatic, or automatic control of the lock system. The automatic controller may be connected to sensors positioned to detect if people are in the lock or not, blocking the gate, or if the gate is fully opened or fully closed or the water levels within the chambers.
In certain embodiments, the participants may be floating in water during the entire transfer from the first water ride to the second water ride. The participants may be swimming in the water or floating upon a floatation device. Preferably, the participants are floating on an inner tube, a floatation board, raft, or other floatation devices used by participants on water rides.
In certain embodiments, the lock system may include multiple movable members formed within the outer wall of the chamber. These movable members may lead to multiple water rides and/or continuous water ride systems coupled to the chamber. The additional movable members may be formed at the same elevational level or at different elevations.
In some embodiments, a first and second movable members formed in the outer wall of a chamber of a lock system may be configured to move vertically into a portion of the wall when moving from a closed position to an open position. The members may be substantially hollow, and have holes in the bottom configured to allow fluid flow in and out of the member. In an open position, the hollow member may be substantially filled with water. To move the member to a closed position, compressed air from a compressed air source may be introduced into the top of the hollow member through a valve, forcing water out of the holes in the bottom of the member. As the water is forced out and air enters the member, the buoyancy of the member may increase and the member may float up until it reaches a closed position. In this closed position, the holes in the bottom of the member may remain submerged, thereby preventing the air from escaping through the holes. To move the member back to an open position, a valve in the top of the member may be opened, allowing the compressed air to escape and allowing water to enter through the holes in the bottom. As water enters and compressed air escapes, the gate may lose buoyancy and sink until it reaches the open position, when the air valve may be closed again.
An advantage to the pneumatic gate system may be that water may be easily transferred from a higher lock to a lower one over the top of the gate. This system greatly simplifies and reduces the cost of valves and pumping systems between lock levels. The water that progressively spills over the top of the gate as it is lowered is at low, near-surface pressures in contrast to water pouring forth at various pressures in a swinging gate lock system. This advantage makes it feasible to eliminate some of the valves and piping required to move water from a higher lock to a lower lock.
In certain embodiments a pneumatic or hydraulic cylinder may be used to vertically move a gate system. An advantage to this system may be that the operator has much more control over the gate than with a gate system operating on a principle of increasing and decreasing the buoyancy. More control of the gate system may allow the gates to be operated in concert with one another, as well as increasing the safety associated with the system. The gate may be essentially hollow and filled with air or other floatation material such as Styrofoam, decreasing the power needed to move the gate.
While water lock systems are described as having only a single chamber coupled to two water rides forming an amusement ride, it should be understood that multiple chambers may be interlocked to couple two or more water rides of a first amusement ride and/or a second amusement ride. By using multiple chambers, a series of smaller chambers may be built rather than a single large chamber. In some situations it may be easier to build a series of chambers rather than a single chamber. For example, use of a series of smaller chambers may better match the slope of an existing hill. Another example is to reduce water depths and pressures operating in each chamber so as to improve safety and reduce structural considerations resulting from increased water pressure differentials. Another example is the use of multiple chambers to increase aesthetics or ride excitement. Another is the use of multiple chambers to increase overall speed and participant throughput of the lock.
The participants may be transferred from the first water ride to the second water ride by entering the chamber and altering the level of water within the chamber. The first movable member, coupled to the first water ride is opened to allow the participants to move into the chamber. The participants may propel themselves by pulling themselves along by use of rope or other accessible handles or be pushed directly with fluid jets or be propelled by a current moving from the lower water ride toward the chamber. The current may be generated using fluid jets positioned along the inner surface of the chamber. Alternatively, a current may be generated by altering the level of water in the first water ride. For example, by raising the level of water in the first water ride a flow of water from the first water ride into the chamber may occur.
After the participants have entered the chamber, the first movable member is closed and the level of water in the chamber is altered. The level may be raised or lowered, depending on the elevation level of the second water ride with respect to the first water ride. If the second water ride is higher than the first water ride, the water level is raised. If the first water ride is at a higher elevation than the second water ride, the water level is lowered. As the water level in the chamber is altered, the participants are moved to a level commensurate with the upper surface of the second water ride. While the water level is altered within the chamber, the participants remain floating proximate the surface of the water. A bottom member preferably moves with the upper surface of the water in the chamber to maintain a relatively constant and safe depth of water beneath the participants. The water level in the chamber, in certain embodiments, is altered until the water level in the chamber is substantially equal to the water level of the second water ride. The second movable member may now be opened, allowing the participants to move from the chamber to the second water ride. In certain embodiments, a current may be generated by filling the chamber with additional water after the level of water in the chamber is substantially equal to the level of water outside the chamber. As the water is pumped in the chamber, the resulting increase in water volume within the chamber may cause a current to be formed flowing from the chamber to the water ride. When the movable member is open, the formed current may be used to propel the participants from the chamber to a water ride. Thus, the participants may be transferred from a first water ride to a second water ride without having to leave the water forming an amusement ride. The participants are thus relieved of having to walk up a hill. The participants may also be relieved from carrying any floatation devices necessary for the amusement ride. Water lock systems may be more fully described in U.S. patent application Ser. No. 09/952,036 and U.S. Pat. No. 6,475,095 which are all incorporated by reference herein.
In some embodiments, elevation systems may be designed to be entertaining and an enjoyable part of the water ride as well as the water rides of the amusement ride which the elevation system is connecting. For example, when the elevation system includes an uphill water slide, the entertainment value may be no less for the elevation system of the continuous water ride than for the connected water rides.
In some embodiments, an exit point of a second water ride of an amusement ride may be coupled to an entry point of a first water ride. Coupling the exit point of the second water ride to the entry point of the first water ride may form a true continuous water ride loop. The continuous water ride may include a second elevation system coupling the exit point of the second water ride to the entry point of the first water ride. The second elevation system may include any of the elevation systems described for use in coupling an exit point of the first water ride to the entry point of the second water ride. The second elevation system may be a different elevation system than the first elevation system. For example, the first elevation system may be an uphill water slide and the second water elevation system may be a conveyor belt system.
In some embodiments, a continuous water ride may include one or more floating queue lines. Floating queue lines may be more fully described in U.S. Patent Publication No. 20020082097. Floating queue lines may assist in coupling different portions of a continuous water ride. Floating queue line systems may be used for positioning participants in an orderly fashion and delivering them to the start of a ride at a desired time. In certain embodiments, this system may include a channel (horizontal or otherwise) coupled to a ride on one end and an elevation system on the other end. It should be noted, however, that any of the previously described elevation systems may be coupled to the water ride by the floating queue line system. Alternatively, a floating queue line system may be used to control the flow of participants into the continuous water ride from a dry position within a station.
In use, participants desiring to participate on a water ride may leave the body of water and enter the floating queue line. The floating queue line may include pump inlets and outlets similar to those in a horizontal channel but configured to operate intermittently to propel participants along the queue line, or the inlet and outlet may be used solely to keep a desired amount of water in the queue line. In the latter case, the channel may be configured with high velocity low volume jets that operate intermittently to deliver participants to the end of the queue line at the desired time.
In certain embodiments, the water moves participants along the floating queue line down a hydraulic gradient or bottom slope gradient. The hydraulic gradient may be produced by out-flowing the water over a weir at one end of the queue after the participant enters the ride to which the queue line delivers them, or by out-flowing the water down a bottom slope that starts after the point that the participant enters the ride. In certain embodiments, the water moves through the queue channel by means of a sloping floor. The water from the outflow of the queue line in any method can reenter the main channel, another ride or water feature/s, or return to the system sump. Preferably the water level and width of the queue line are minimized for water depth safety, participant control and water velocity. These factors combined deliver the participants to the ride in an orderly and safe fashion, at the preferred speed, with minimal water volume usage. The preferred water depth, channel width and velocity would be set by adjustable parameters depending on the type of inflatable vehicle, participant comfort and safety, and water usage. Decreased water depth may also be influenced by local ordinances that determine level of operator or lifeguard assistance, the preferred being a need for minimal operator assistance consistent with safety.
In some embodiments, amusement rides may include exits or entry points at different portion of the amusement ride. Floating queue lines coupling different portions and/or rides forming an amusement ride may include exit and/or entry points onto the continuous water ride. Exit/entry points may be used for emergency purposes in case of, for example, an unscheduled shutdown of the amusement water ride. Exit/entry points may allow participants to enter/exit the amusement water ride at various designated points along the ride during normal use of the amusement water ride. Participants entering/exiting the continuous water ride during normal use of the ride may not disrupt the normal flow of the ride depending on where the entry/exit points are situated along the course of the ride.
Embodiments disclosed herein provide an interactive control system for an amusement ride and/or portions of the amusement ride. In certain embodiments, the control system may include a programmable logic controller. The control system may be coupled to one or more activation points, participant detectors, and/or flow control devices. In addition, one or more other sensors may be coupled to the control system. The control system may be utilized to provide a wide variety of interactive and/or automated water features. In some embodiments, participants may apply a participant signal to one or more activation points. The activation points may send activation signals to the control system in response to the participant signals. The control system may be configured to send control signals to a water system, a light system, and/or a sound system in response to a received activation signal from an activation point. A water system may include, for example, a water effect generator, a conduit for providing water to the water effect generator, and a flow control device. The control system may send different control signals depending on which activation point sent an activation signal. The participant signal may be applied to the activation point by the application of pressure, moving a movable activating device, a gesture (e.g., waving a hand), interrupting a light beam, a participant identifier and/or by voice activation. Examples of activation points include, but are not limited to, hand wheels, push buttons, optical touch buttons, pull ropes, paddle wheel spinners, motion detectors, sound detectors, and levers.
The control system may be coupled to sensors to detect the presence of a participant proximate to the activation point. The control system may be configured to produce one or more control systems to active a water system, sound system, and/or light system in response to a detection signal indicating that a participant is proximate to an activation point. The control system may also be coupled to flow control devices, such as, but not limited to: valves and pumps. Valves may includes air valves and water valves configured to control the flow air or water, respectively, through a water feature. The control system may also be coupled to one or more indicators located proximate to one or more activation points. The control system may be configured to generate and send indicator control signals to turn an indicator on or off. The indicators may signal a participant to apply a participant signal to an activation point associated with each indicator. An indicator may signal a participant via a visual, audible, and/or tactile signal. For example, an indicator may include an image projected onto a screen.
In some embodiments, the control system may be configured to generate and send one or more activation signals in the absence of an activation signal. For example, if no activation signal is received for a predetermined amount of time, the control system may produce one or more control signals to activate a water system, sound system, and/or light system.
Throughout the system electronic signs or monitors may be positioned to notify participants or operators of various aspect of the system including, but not limited to: operational status of any part of the system described herein above; estimated waiting time for a particular ride; and possible detours around non operational rides or areas of high participant density.
In some embodiments, a water amusement park may include a cover or a screen. Screens may be used to substantially envelope or cover a portion of a water amusement park. Portions of the screen may be positionable. Positionable screen portions may allow portions of the park to be covered or uncovered. The decision to cover or uncover a portion of the water amusement park may be based on the weather. Inclement weather may prompt operators to cover portions of the waterpark with the positionable screens. While clear warm weather may allow operators to move the positionable screen so portions of the water amusement park remain uncovered.
In some embodiments, positionable screens may be formed from substantially translucent materials. Translucent materials may allow a portion of the visible light spectrum to pass through the positionable screens. Translucent materials may inhibit transmittance of certain potentially harmful portions of the light spectrum (e.g., ultraviolet light). Filtering out a potentially harmful portion of the light spectrum may provide added health benefits to the water amusement park relative to uncovered water amusement parks. A non-limiting example of possible screen material may include Foiltech. Foiltech has an R protective value of about 2.5. A non-limiting example of possible screen material may include polycarbonates. Polycarbonates may have an R protective value of about 2. In some embodiments, multiple layers of screen material (e.g., polycarbonate) may be used. Using multiple layers of screen material may increase a screen materials natural thermal insulating abilities among other things. Portions of the screening system described herein may be purchased commercially at Arqualand in the United Kingdom.
In some embodiments, portions of the positionable screen may assist in collecting solar radiation. Solar radiation collected by portions of the positionable screen may be used to increase the ambient temperature in the area enclosed by the screen. Increasing the ambient temperature in enclosed portions of the water amusement park using collected solar radiation may allow the water amusement park to remain open to the public even when the outside temperature is uncomfortably cold and unconducive to typical outside activities.
In some embodiments, positionable screens may be used to enclose portions of a water amusement park. Enclosed areas of the water amusement park may function as a heat sink. Heat emanating from bodies of water within the enclosed area of the water amusement park may be captured within the area between the body of water and the positionable screens. Heat captured under the positionable screens may be recirculated back into the water. Captured heat may be recirculated back into the water using heat pumps and/or other common methods known to one skilled in the art.
In some embodiments, screens may be mounted on wheels and/or rollers. Screen may be formed from relatively light but strong materials. For example, panels may be formed from polycarbonate for other reasons described herein, while structural frameworks supporting these panels may be formed from, for example, aluminum. Lightweight, well-balanced, support structures on wheels/rollers might allow screens to be moved manually by only a few operators. Operators might simply push screens into position. Mechanisms may installed to assist operators in manually positioning screens (e.g., tracks, pulley mechanisms).
Examples of systems which facilitate movement of screens over bodies of water and/or channels (e.g., track based systems) are illustrated in U.S. Pat. Nos. 4,683,686 to Ozdemir and 5,950,253 to Last, each of which is incorporated by reference as if fully set forth herein.
In some embodiments, some water amusement park areas may include immovable screens substantially enclosing the water amusement area (e.g., a dome structure). While other water amusement areas may remain uncovered year round. Channels may connect different water amusement areas. Channels may include portions of a natural river. Channels may include portions of man-made rivers or reservoirs. Channels may include portions of a natural or man-made body of water (e.g., a lake). The portions of the natural or man-made body of water may include artificial or natural barriers to form a portion of the channel in the body of water. Channels may include positionable screens as described herein. In some embodiments, an entire waterpark may include permanent and/or positionable screens covering the waterpark. In some embodiments, only portions of a waterpark may include permanent and/or positionable screens.
There are advantages to covering the channels and/or portions of the park connected by the channels as opposed to covering the entire park in, for example, one large dome. One advantage may be financial, wherein enclosing small portions and/or channels of a park is far easier from an engineering standpoint and subsequently much cheaper than building a large dome. Channels that extend for relatively long distances may be covered far more easily than a large dome structure extending over the same distance which covers the channel and much of the surrounding area. It is also far easier to retract portions of the screens described herein to selectively expose portions of a waterpark than it is to selectively retract portions of a dome.
Screen systems may be more fully described in U.S. patent application Ser. No. 10/693,654 to Henry et al. which is incorporated by reference as if fully set forth herein.
In some embodiments, water amusement parks may include participant identifiers. Participant identifiers may be used to locate and/or identify one or more participants at least inside the confines of the water amusement park. Participant identifiers may assist control systems in the water amusement park. Participant identifiers may be considered as one portion of a water amusement park control system in some embodiments. Participant identifiers may be used for a variety of functions in the water amusement park.
In some embodiments, a plurality of personal identifiers may be used in combination with a water amusement park. Personal identifiers may be provided to each individual participant of the water amusement park. Personal identifiers may be provided for each member of staff working at the water amusement park. Within the context of this application the term “participant” may include anyone located in the confines of the water amusement park including, but not limited to, staff and/or patrons. A plurality of sensors may be used in combination with the personal identifiers. Personal identifiers may function as personal transmitters. Sensors may function as receiver units. Sensors may be positioned throughout the water amusement park. Sensor may be positioned, for example, at particular junctions (i.e., coupling points) along, for example, a continuous water ride. Sensors may be placed along, for example, floating queue lines, channels, entry/exit points along water rides, and/or entry/exit points between portions of the water amusement park. Personal identifiers working in combination with sensors may be used to locate and/or identify participants.
In some embodiments, personal identifiers and/or sensors may be adapted for ultrasonic, or alternatively, for radio frequency transmissions Personal identifiers and/or sensors may operate on the same frequency. Identification of individual personal identifiers may be achieved by a pulse timing technique whereby discrete time slots are assigned for pulsing by individual units on a recurring basis. Pulses received from sensors may be transmitted to decoder logic which identifies the locations of the various transmitter units in accordance with the time interval in which pulses are received from various sensors throughout the water amusement park. A status board or other display device may display the location and/or identity of the participant in the water amusement park. Status of a participant may be displayed in a number of ways. Status of a participant may be displayed as some type of icon on a multi-dimensional map. Status of a participant may be displayed as part of a chart displaying throughput for a portion of the water amusement park.
In some embodiments, programming means may be provided for a participant identifier. Participant identifiers may be substantially identical in construction and electronic adjustment. Participant identifiers may be programmed to predetermined pulse timing slots by the programming means. Any participant may use any participant identifier. The particular pulse timing slot may be identified as corresponding with a particular participant using a programmer. Participant identifiers may be associated with a particular participant by positioning the participant identifier in a receptacle. The receptacle may be coupled to the programmer. Receptacles may function to recharge a power source powering the participant identifier. In some embodiments, a receptacle may not be necessary and the personal identifier may be associated in the water amusement park with a particular participant via wireless communication between the personal identifier and a programmer.
In some embodiments, participant identifiers may be removably coupled to a participant. The participant identifier may be band which may be coupled around an appendage of a participant. The band may be attached around, for example, an arm and/or leg of a participant. In some embodiments, identifiers may include any shape. Identifiers may be worn around the neck of a participant much like a medallion. In some embodiments, an identifier may be substantially attached directly to the skin of a participant using an appropriate adhesive. In some embodiments, an identifier may be coupled to an article of clothing worn by a participant. The identifier may be coupled to the article of clothing using, for example, a “safety pin”, a plastic clip, a spring clip, and/or a magnetic based clip. In some embodiments, identifiers may be essentially “locked” after coupling the identifier to a participant. A lock may inhibit the identifier from being removed from the participant by anyone other than a staff member except under emergency circumstances. Locking the identifier to the participant may inhibit loss of identifiers during normal use of identifiers. In some embodiments, a participant identifier may be designed to detach from a participant under certain conditions. Conditions may include, for example, when abnormal forces are exerted on the participant identifier. Abnormal forces may result from the participant identifier becoming caught on a protrusion, which could potentially endanger the participant.
In some embodiments, circuitry and/or a power source may be positioned substantially in the personal identifiers. Positioning any delicate electronics in the personal identifier, such that material forming the personal identifier substantially envelopes the electronics, may protect sensitive portions of the personal identifier from water and/or corrosive chemicals typically associated with a water amusement park. Participant identifiers may be formed from any appropriate material. Appropriate materials may include materials that are resistant to water and corrosive chemicals typically associated with a water amusement park. Participant identifiers may be at least partially formed from materials which are not typically thought of as resistant to water and/or chemicals, however, in some embodiments materials such as these may be treated with anticorrosive coatings. In certain embodiments, participant identifiers may be formed at least partially from polymers.
In some embodiments, a personal identifier may be brightly colored. Bright colors may allow the identifier to be more readily identified and/or spotted. For example, if the identifier becomes decoupled from a participant the identifier may be more easily spotted if the identifier is several feet or more under water. In some embodiments, a personal identifier may include a fluorescent dye. The dye may be embedded in a portion of the personal identifier. The dye may further assist in spotting a lost personal identifier under water and/or under low light level conditions (e.g., in a covered water slide).
Personal identifiers which may be adapted to be used with the systems and methods described herein are more fully described in U.S. patent application Ser. No. 10/693,654 to Henry et al which is incorporated by reference herein.
Other components which may be incorporated into a participant identifier system are disclosed in the following U.S. patents, herein incorporated by reference: a personal locator and display system as disclosed in U.S. Pat. No. 4,225,953; a personal locator system for determining the location of a locator unit as disclosed in U.S. Pat. No. 6,362,778; a low power child locator system as disclosed in U.S. Pat. No. 6,075,442; a radio frequency identification device as disclosed in U.S. Pat. No. 6,265,977; and a remote monitoring system as disclosed in U.S. Pat. No. 6,553,336.
In some embodiments, participant identifiers may be used as part of an automated safety control system. Participant identifiers may be used to assist in determining and/or assessing whether a participant has been separated from their vehicle (e.g., inflatable vehicles or inner tubes). Sensors may be positioned along portions of a water amusement park. For example sensors may be placed at different intervals along a water amusement ride. Intervals at which sensors are placed may be regular or irregular. Placement of sensors may be based on possible risk of a portion of a water amusement ride. For example, sensors may be placed with more frequency along faster moving portions of a water amusement ride where the danger for a participant to be separated from their vehicle is more prevalent.
In some embodiments, vehicle identifiers may be used to identify a vehicle in a water amusement park. The vehicle identifier may be used to identify the location of the vehicle. The vehicle identifier may be used to identify the type of vehicle. For example, the vehicle identifier may be used to identify how many people may safely ride in the vehicle.
In some embodiments, sensors near an entry point of a portion of a water amusement ride may automatically assess a number of participant identifiers/participants associated with a particular vehicle. Data such as this may be used to assess whether a participant has been separated from their vehicle in another portion of the water amusement ride.
In some embodiments, an operator may manually input data into a control system. Data input may include associating particular participant identifier(s) and/or the number of participants with a vehicle.
In some embodiments, a combination of automated and manual operation of a safety control system may be used to initially assess a number of participants associated with a vehicle. For example, an operator may provide input to initiate a sensor or a series of sensors to assess the number of participants associated with the vehicle. The assessment may be conducted at an entry point of a water amusement ride.
In certain embodiments, personal identifiers may be used in combination with a recording device. The recording device may be positioned in a water amusement park. One or more recording devices may be used throughout the water amusement park. The participant identifier may be used to activate the recording device. The participant identifier may be used to remotely activate the recording device. The recording device may include a sensor as described herein. The identifier may automatically activate the recording device upon detection by the sensor coupled to the recording device. The participant may activate the recording device by activating the personal identifier using participant input (e.g., a mechanical button, a touch screen). The participant identifier may activate one or more recording devices at one or more different times and/or timing sequences. For example several recording devices may be positioned along a length of a downhill slide. A participant wearing a personal identifier may activate (automatically or upon activation with user input) a first recording device positioned adjacent an entry point of the slide. Activating the first recording device may then activate one or more additional recording devices located along the length of the downhill water slide. Recording devices may be activated in a particular sequence so as to record the participant progress through the water slide.
In some embodiments, a recording device may record images and/or sound. The recording device may record other data associated with recorded images and/or sound. Other data may include time, date, and/or information associated with a participant wearing a participant identifier. The recording device may record still images and/or moving (i.e., short movie clips). Examples of recording devices include, but are not limited to, cameras and video recorders.
In some embodiments, a recording device may be based on digital technology. The recording device may record digital images and/or sound. Digital recording may facilitate storage of recorded events, allowing recorded events to be stored on magnetic media (e.g., hard drives, floppy disks, etc. . . . ). Digital recordings may be easier to transfer as well. Digital recordings may be transferred electronically from the recording device to a control system and/or processing device. Digital recordings may be transferred to the control system via a hard-wired connection and/or a wireless connection.
Upon recording an event, the recording device may transfer the digital recording to the control system. The participant may purchase a copy of the recording as a souvenir. The participant may purchase a copy while still in a water amusement park, upon exiting the water amusement park, and/or at a later date. The control system may print a hard copy of the digital recording. The control system may transfer an electronic copy of the recorded event to some other type of media that may be purchased by the participant to take home with them. The control system may be connected to the Internet. Connecting the control system to the Internet may allow a participant to purchase a recorded event through the Internet at a later time. A participant may be able to download the recorded event at home upon arranging for payment.
In some embodiments, personal identifiers may be used in combination with sensors to locate a position of a participant in a water amusement park. Sensors may be positioned throughout the waterpark. The sensors may be connected to a control system. Locations of sensors throughout the waterpark may be programmed into the control system. The participant identifier may activate one of the sensors automatically when it comes within a certain proximity of the sensor. The sensor may transfer data concerning the participant (e.g., time, location, and/or identity) to the control system.
In some embodiments, participant identifiers may be used to assist a participant to locate a second participant. For example, identifiers may assist a parent or guardian to locate a lost child. The participant may consult an information kiosk or automated interactive information display. The interactive display may allow the participant to enter a code, name, and/or other predetermined designation for the second participant. The interactive display may then display the location of the second participant to the participant. The location of the second participant may be displayed, for example, as an icon on a map of the park. Security measures may be taken to ensure only authorized personnel are allowed access to the location of participants. For example, only authorized personnel (e.g., waterpark staff) may be allowed access to interactive displays and/or any system allowing access to identity and/or location data for a participant. Interactive displays may only allow participants from a predetermined group access to participant data from their own group.
In some embodiments, participant identifier may be used to assist in regulating throughput of participants through portions of a water amusement park. Participant identifiers may be used in combination with sensors to track a number of participants through a portion of the water amusement park. Keeping track of numbers of participants throughout the waterpark may allow adjustments to be made to portions of the waterpark. Adjustments made to portions of the waterpark may allow the portions to run more efficiently. Adjustments may be at least partially automated and carried out by a central control system. Increasing efficiency in portions of the waterpark may decrease waiting times for rides.
In some embodiments, sensors may be positioned along one or both sides of a floating queue line. Sensors in floating queue lines may be able to assist in detecting participants wearing participant identifiers. Data including about participants in the floating queue lines may be transferred to a control system. Data may include number of participants, identity of the participants, and/or speed of the participants through the floating queue lines. Based on data collected from the sensors, a control system may try to impede or accelerate the speed and/or throughput of participants through the floating queue line as described herein. Adjustment of the throughput of participants through the floating queue lines may be fully or partially automated. As numbers of participants in a particular ride increase throughput may decrease. In response to data from sensors the control system may increase the flow rate of participants to compensate. The control system may automatically notify waterpark staff if the control system is not able to compensate for increased flow rate of participants.
In certain embodiments (an example of which is depicted in
In some embodiments, a queue system may include water deep enough to substantially float buoyant vehicles. The queue system may include fluid jets located along the length of a path system forming the queue system. The fluid jets may include high velocity low volume fluid jets. The jets may use pressurized or high velocity fluids directed at participants/vehicles to propel them along a surface. The surface may include an incline, a decline, or be substantially level. Fluids may include liquids (e.g., water) and/or gases (e.g., air). Jets may be set at an appropriate angle to provide propulsive power for a vehicle. Jets may automatically orient themselves to a proper angle when connected to an automated control system. Jets may be positioned along floors, walls, and/or ceilings. Fluid jets using liquids to propel participant carriers along a portion of a water path system may be used in combination with dewatering systems. Dewatering systems may be especially useful when fluid jets using liquids are used to propel participant carriers up an incline. Dewatering systems may be used to remove liquid running down an inclined surface, such that the momentum of the liquid does not detract from the momentum of fluid expelled from fluid jets used to propel participants. Dewatering systems may be more fully described in U.S. Pat. No. 5,011,134 which is incorporated by reference herein.
Fluid jet systems used for vehicle propulsion in amusement rides may be more fully described in U.S. Pat. Nos. 5,213,547 to Lochtefeld and 5,503,597 to Lochtefeld et al. which are incorporated by reference as if fully set forth herein.
In some embodiments, participant identifiers may be used with interactive games. Interactive games may include interactive water games. Interactive games may be positioned anywhere in a water amusement park. Interactive games may be positioned along a floating queue line, an elevation system, and/or a water ride. Interactive games positioned along portions of the water amusement park where delays are expected may make waiting more tolerable or even pleasurable for participants.
An interactive water game including a control system as described above may include a water effect generator; and a water target coupled to the control system. In some embodiments, the water effect generator may include a water cannon, a nozzle, and/or a tipping bucket feature. The water effect generator may be coupled to a play structure. During use a participant may direct the water effect generator toward the water target to strike the water target with water. A participant may direct the water effect using a participant identifier to activate the water effect generator. Upon being hit with water, the water target may send an activation signal to the control system. Upon receiving an activation signal from the water target, the control system may send one or more control signals to initiate or cease predetermined processes.
The water target may include a water retention area, and an associated liquid sensor. In some embodiments, the liquid sensor may be a capacitive liquid sensor. The water target may further include a target area and one or more drains. The water target may be coupled to a play structure.
In some embodiments, the interactive water game may include one or more additional water effect generators coupled to the control system. Upon receiving an activation signal from the water target, the control system may send one or more control signals to the additional water effect generator. The additional water effect generator may be configured to create one or more water effects upon receiving the one or more control signals from the control system. For example, the one or more water effects created by the additional water effect generator may be directed toward a participant. The additional water effect generator may include, but is not limited to: a tipping bucket feature, a water cannon, and/or a nozzle. The additional water effect generator may be coupled to a play structure.
A method of operating an interactive water game may include applying a participant signal to an activation point associated with a water system. The participant signal may be fully automated and originate from a participant identifier. The participant signal may be activated when a participant wearing the participant identifier positions themselves in predetermined proximity of the activation point. Participant input may activate the participant signal using the participant identifier. An activation signal may be produced in response to the applied participant signal. The activation signal may be sent to a control system. A water system control signal may be produced in the control system in response to the received activation signal. The water system control signal may be sent from the control system to the water system. The water system may include a water effect generator. The water effect generator may produce a water effect in response to the water system control signal. The water effect generator may be directed toward a water target to strike the water target with water. An activation signal may be produced in the water target, if the water target is hit with water. The water target may send the activation signal to the control system. A control signal may be produced in the control system in response to the received water target activation signal. In some embodiments, the interactive water game may include an additional water effect generator. The control system may direct a control signal to the additional water effect generator if the water target is struck by water. The additional water effect generator may include, but is not limited to: a water cannon, a nozzle, or a tipping bucket feature. The additional water effect generator may produce a water effect in response to a received control signal. The water effect may be directed toward a participant.
Amusement rides including water channels (e.g., artificial rivers) may include adjustable mechanisms or devices capable of changing the course of a river. Adjustable mechanisms such as these may be described as adjustable weirs. Weirs are generally defined as a dam placed across a river or canal to raise or divert the water, or to regulate or measure the flow of water.
A mechanism is described that controls the flow of water for an artificial river, in the context of waterpark, and in the setting of participants and participant carriers within the controlled river. Adjustable weirs may be optimally producible, easily installed, and/or readily maintained. Safety to both participants and personnel may be a requirement. Adjustable weirs may function to alter flow characteristics of water in a channel, produce downstream rapids of varying degree, and/or undulations to such in dynamic fashion. Adjustable weirs may function to fully dam up the upstream body of water (with only moderate leakage), whether in off-duty mode and/or in the event of power failure, such that, for example, upper water volumes may not overflow lower regions of the same river system.
Adjustable weirs may include safety fail-safes. For example an adjustable weir may include a loss of power mode, where the weir reverts to/maintains an upward (water-retaining) position. Adjustable weir fail-safes may include keeping gaps between static and moving features to a safe minimum, and/or inherently precluding access. Adjustable weir fail-safes may include ensuring no serviceable equipment (except for fundamental overhaul, coinciding with river drainage) may be located behind or beneath the primary mechanism. Advantages of ensuring no serviceable equipment is located behind or beneath the primary mechanism may ensure accessibility to serviceable equipment (e.g., when in the failsafe position, a huge body of water may be under retention). Serviceable equipment and/or motive components may be located outboard of the main channel, whether below grade (e.g., in pits), and/or above (e.g., in enclosures).
Adjustable weirs may include serviceable equipment and components which may be removed/exchanged with comparative rapidity and minimal disruption/removal of other components. Adjustable weirs may require minimal maintenance. Adjustable weirs may include drive mechanisms which are chemically benign (e.g., electrical or pneumatic). Chemically benign drive mechanisms are advantageous when river systems (natural or artificial) are used so as to inhibit introduction of chemicals (e.g., hydraulic fluid) into the environment. Non-engineered parts may be used whenever possible for the construction of adjustable weirs, chosen at least for durability and ready availability. Adjustable weirs may include lock-out features, such that the weir table may be redundantly secured into either of its extreme positions, regardless of hydraulic conditions in the river. Positioning of an adjustable weir may be capable of dynamic operation, taking into account the changing hydraulic forces of the moving volume of water.
Closing the gaps are fixed upstream plate 170 (secured to the concrete riverbed), and side shrouds 172. Both elements may continuously fit to rotatable contour 174, regardless of its position. The rotatable contour depicted in the associated figures is in the shape of an “hourglass,” however it should be noted this is just one example of many possible shapes the rotatable contour may assume.
To prevent water and/or participants from being sucked down behind adjustable weir 168, trailing plates 176 may be attached to the pivoting weir table. An upstream leaf is hinged directly thereto; a horizontal plate may be dragged behind. Together, a benign (though moving) riverbed is presented, with close proximity to the concrete walls (and minimal gaps).
In certain embodiments, outboard pits may be covered—though size, shape, theming, etc., of such may be determined on an application basis.
As a variety of drive means may be applied, none are presented in the
