Description

WATER BASED AMUSEMENT PARK TRANSPORTATION RIDE SYSTEM

INTRODUCTION

The present application relates generally to amusement attractions and rides.

More particularly, the disclosure generally relates to a system and method for an amusement ride elevation and/or descending system.

BACKGROUND

During the last 30 years, the growth in participatory family water-based recreation, and in water oriented ride attractions in the traditional themed amusement parks, has been unprecedented. Current attractions, for example, waterslides, river rapid rides, 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, or catch unit where after the cycle repeats.

Generally speaking, the traditional downhill water rides are short in duration and have limited throughput capacity. The combination of these two factors can lead to a situation in which patrons of the parks typically form long queues and have a long waiting time for a ride that, although exciting, lasts only a few seconds. Additional problems like hot and sunny weather, wet patrons etc. 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 within industry.

At least in preferred embodiments the present invention provides an interesting, new and alternative ride in an attempt to keep waterpark participants entertained, thereby prolonging their overall experience and enjoyment of the park. Using preferred embodiments of the present invention it may be possible for a patron to ride from any given location to another within a waterpark. Further, the invention generally relates to amusement rides and methods for transporting participant/ participants and their vehicles between different elements/areas within an amusement park in a safe, efficient and interesting manner.

It is known from PCT/GB98/01008 to provide a water ride comprising an inclined hollow rotating tube having an internal screw thread. However, there are various limitations with the arrangement disclosed in this document. It is necessary for the individual to align themselves with the entrance to the tube so that they are positioned ready for transportation. If the individual is not properly positioned, the rotation of the tube may cause them to be tipped out of their vehicle. The same problem may occur when the individual tries to exit the tube. Thus, the water ride disclosed in the prior art is potentially dangerous.

SUMMARY OF THE INVENTION

Viewed from a first aspect, the present invention relates to a system for conveying an individual in a leisure park, the system comprising: a tube having an inlet and an outlet; and a rotatable screw for conveying the individual from said inlet to said outlet; the system further comprising an inlet flow control means adapted operatively to cause a surge of water into said inlet suitable for biasing an individual into the tube; and/or an outlet flow control means adapted operatively to cause a surge of water out of said outlet for biasing an individual out of the.

The surge of water may correspond to an increased flow rate of the water as it enters the inlet and/or exits the outlet. Preferably, the surge of water is sufficient to transport the individual into the inlet and/or out of the outlet respectively. A surge of water into the inlet may ensure that an individual is introduced fully into the tube and is preferably clear of the inlet as the screw rotates. Likewise, a surge of water out of the outlet may ensure that an individual is expelled from the tube and is clear of the outlet as the screw rotates. The system may comprise both an inlet and an outlet flow control means; or only one of said flow control means. The tube inlet is preferably located in a body of water, for example a pool or a stream. The individual may enter the tube directly from the body of water. The individual may have a floatation device, such as an inflatable ring or float. Preferably, the individual may be in a vehicle and the individual enters and exits the tube while in said vehicle. More than one user may be in the vehicle. The system is preferably configured such that the individual(s) and the vehicle are drawn into the tube by the inlet flow control means; and/or expelled from the tube by the outlet flow control means.

The inlet flow control means and/or the outlet flow control means may each comprise one or more jets of water. Preferably, however, the flow rate of water entering the tube from the body of water and/or exiting the tube is controlled by the associated flow control means. The inlet flow control means preferably comprises a movable inlet barrier. The inlet barrier may be movable between a first position for restricting or preventing the flow of water into the inlet and a second position for allowing water to flow into said inlet. The inlet barrier could, for example, be raised/lowered or pivoted by suitable drive means, such as one or more hydraulic pistons.

Preferably the inlet barrier is rotatable. The inlet barrier is preferably coupled to the screw and, in use, may rotate with the screw.

A recess or aperture is preferably provided in the inlet barrier. When the aperture is below the surface of the water, the water can enter the tube. The recess is preferably sized to allow the individual to pass through it. In use, a surge of water may enter through the aperture in the inlet barrier causing an individual to be transported into the tube.

The inlet barrier may be a collar or a flange. The collar or flange is preferably provided proximal the inlet. The collar or flange may be defined by or be contiguous with said internal screw thread or the tube. The inlet flow control means may be defined by or be contiguous with an induction thread formed in the screw.

The outlet flow control means preferably comprises a movable outlet barrier. The outlet barrier may be movable between a first position for restricting or preventing the flow of water out of the outlet and a second position for allowing water to flow out of said outlet. The outlet barrier could, for example, be raised/lowered or pivoted by suitable drive means. Preferably, however, the outlet barrier is rotatable. The outlet barrier is preferably coupled to the screw and, in use, rotates with the screw.

An aperture or recess is preferably provided in the outlet barrier. When the aperture is positioned at the bottom of the tube, the water can exit the tube. The aperture is preferably sized to allow the individual to pass through it.

An outlet ramp may be provided extending at least substantially from said screw to said outlet, the outlet ramp being inclined downwardly towards the outlet operatively to allow the individual to slide down the outlet ramp and out of the tube. The outlet ramp is preferably formed in a sidewall of said tube. The outlet ramp preferably extends from the final turn of the screw (i.e. the section of the screw proximal the outlet) to the outlet. The outlet ramp may be used in conjunction with or instead of an outlet flow control means.

A preferred embodiment of the present invention comprises an inlet flow control means at the inlet of the tube; and an outlet ramp at the outlet of the tube. The system according to this embodiment does not have an outlet flow control means. Viewed from a further aspect, the present invention relates to a system for conveying an individual in a leisure park, the system comprising: a tube having an inlet and an outlet; and a rotatable screw for conveying the individual from said inlet to said outlet; the system further comprising an outlet ramp extending at least substantially from said screw to said outlet, the outlet ramp being inclined downwardly towards the outlet operative Iy to allow the individual to slide down the outlet ramp and out of the tube.

The outlet ramp preferably extends from the final turn of the screw (i.e. the section of the screw proximal the outlet) to the outlet.

Preferably the outlet ramp is adapted to raise the individual above the level of the outlet to enable the individual to slide out of the outlet. The outlet ramp may be defined by a circle sector of the tube having a reduced diameter. In this arrangement, the individual may be lifted by the outlet ramp to a height above the outlet of the tube (which may be defined by a lip or flange).

Alternatively, the outlet ramp may be defined by a circle sector of the tube having an increased diameter. In this arrangement the ramp typically falls away towards the outlet of the tube.

A portion of the outlet ramp may be operatively substantially horizontal. This horizontal section may provide a lead-in to the inclined section of the outlet ramp.

The system preferably has an inlet flow control means of the type described herein. The systems described herein may comprise a screw separate from the tube. For example, the tube could be fixed and the screw rotatable. In arrangements in which the tube is fixed, the tube could be open along part or all of its length. Preferably, however, the screw is formed on an interior of the tube and, in use, the screw and the tube rotate together. The inlet may be tapered to define a truncated cone.

At least one step may be formed in the screw thread. The at least one step may allow an individual to exit the system if it stops mid-cycle. The at least one step may be a continuous spiral extending the length of the screw thread to allow access irrespective of the orientation of the screw. Alternatively, one or more ladders may be provided. In use, the tube is inclined at an angle relative to the horizontal. The inlet is typically arranged below the level of the outlet.

The screw preferably defines a guide surface for conveying the individual along the length of the tube. The guide surface is preferably inclined relative to a longitudinal axis of the tube at an angle approximately equal to the angle at which the longitudinal axis of the tube is operatively inclined relative to the vertical. Thus, the guide surface is preferably oriented substantially vertically when it is at the bottom of the tube. The tube is preferably rotatable and has an inner profile comprising an at least substantially continuous inwardly projecting helical ridge forming said screw and a helical platform for supporting the individual as the tube rotates; the platform being inclined at an angle relative to a longitudinal axis of the tube. Preferably, the helical platform is operatively arranged substantially or generally horizontally. The platform is preferably operatively arranged so as to be substantially or generally horizontal in the region where the individual(s) travel. In use, the individual may be supported on a substantially horizontal platform or may float in a pool having a substantially horizontal base. This arrangement is advantageous since it may reduce the volume of water that is transported by the tube and may also make it easier for an individual to exit the tube.

Viewed from a further aspect, the present invention relates to a system for conveying an individual in a leisure park, the system comprising a rotatable tube having an inlet, an outlet and an at least substantially continuous internal screw thread for conveying the individual from said inlet to said outlet; wherein the tube has an inner profile comprising said screw thread and a helical platform for supporting the individual as the tube rotates; the platform being inclined at an angle relative to a longitudinal axis of the tube. The platform is preferably operatively arranged so as to be substantially or generally horizontal in the region where the individual(s) travel. In use, the individual may be supported on a substantially horizontal platform or may float in a pool having a substantially horizontal base defined by the platform. The system may transport an individual from a first body of water along with a pool of water. The arrangement whereby the platform is inclined relative to the longitudinal axis of the tube is advantageous since, at least in preferred embodiments, the volume of water transported with the individual may be reduced. By inclining the platform relative to the longitudinal axis of the tube, when it is positioned at the bottom of the tube (i.e. it is positioned such that it supports the individual(s) and/or a pool of water) the angle at which the platform is inclined in a longitudinal direction relative to the horizontal may be reduced or may be substantially zero degrees (i.e. horizontal). Advantageously, the platform may provide an exit route for an individual travelling in the tube, for example in the event of a mechanical failure. The individual may climb from thread to thread and walk along the lowermost region of the tube where the platform is substantially or generally horizontal.

The platform is preferably inclined at an angle relative to the longitudinal axis of the tube which is substantially or approximately equal to the angle at which the longitudinal axis of the tube is operatively inclined to the horizontal. The platform may have a substantially or generally flat or rectilinear profile in a longitudinal direction. Alternatively, the platform could define an arcuate profile (either concave or convex) in a longitudinal direction. The platform could even have a rippled, ridged, sinusoidal, irregular or saw tooth profile. The platform and the internal screw thread may be formed integrally. Indeed, the platform may be formed and/or defined by said internal screw thread.

The systems described herein preferably comprise a circular tube. However, in certain embodiments, it may be desirable for the tube to have non-circular transverse cross-sections. The tube may have an elliptical, oval or ovoid cross-section. Indeed, the cross-section of the tube may be used to provide the desired inlet and/or outlet flow control means. For example, if the tube has an ovoid cross-section proximal the inlet this may provide the desired surge in flow.

Viewed from a yet further aspect, the present invention relates to a system for conveying an individual in a leisure park, the system comprising: a tube having an inlet and an outlet; and a rotatable screw for conveying the individual from said inlet to said outlet; wherein said inlet and/or said outlet is/are formed in a sidewall of said tube. An inlet ramp and/or an outlet ramp may be associated with the respective inlet and/or outlet. Preferably the inlet ramp and/or the outlet ramp extend in a generally tangential direction. Viewed from a further aspect, the present invention relates to a water ride for use in a leisure park comprising an inclined hollow rotating tube having a screw thread on its internal surface, the first end of the tube being at a lower water level and the second end of the tube being at a higher water level wherein an individual entering the tube at one level will be carried to the other level by a body of water moving along the internal thread as the tube rotates about its axis. Accordingly an entry collar, and the exit moulding will combine to ensure that participants and their floatation devices are correctly spaced for safe entry and exit. The rotation of the threaded tube will provide participants with a new and entertaining method of elevated transport. When arranged in series, participants can reach almost any given location. Preferably, an individual is carried using a floating carrying means, by the body of water moving along the internal screw thread.

Preferably, the hollow tube is constructed such that the configuration of the internal screw thread provides an unobstructed central area to allow a clear view through the hollow tube. Preferably the body of water moving along the internal screw thread will be deep enough for the participant/participants and their floatation devices to float but could be at a lesser depth to provide lubrication only or a combination of the both.

Preferably the hollow tube can be made to different dimensions thereby varying the number of users. The angle of incline of the hollow tube can also be varied to suit location requirements.

Preferably the internal screw thread will be designed to infill the floor section of the ponds created by the thread thereby reducing the volume of water being carried and also presenting a flat base between threads should it be necessary for a participant/participants to stand away from their floatation device at any time.

Preferably at the point of entry, the channel will be of sufficient width to allow one participant or group of participants and their floatation device at a time to approach the rotating ride.

Preferably the entry collar will present a barrier to the participant/participants and their floatation vehicle at the beginning of the ride.

Preferably the barrier formed by the entry collar will be shaped to be the same height or greater than the pitch of the internal screw thread and will be equal to or greater than the depth of water being held back.

Preferably the open section of the entry collar will present itself to the participant/participants and their floatation device as the ride turns about its axis and in doing so will allow water to rush into the first open thread section, and allowing the awaiting participant/participants and their floatation device to ride in at the. same moment.

Preferably as the ride turns about its axis, the gap in the entry collar will close off the flow of water as it passes the lower part of the ride. In doing so it will re present the barrier to hold back the water and the next participant/participants and their floatation device who will be awaiting the next revolution of the ride and their turn to enter.

The entry collar system is particularly suitable for rides with a diameter suitable for single person use but is equally suitable for larger diameter rides.

Preferably on larger diameter rides intended for larger floatation devices, a special cone shaped device may be used to reduce the diameter of the opening. The collar can still be used where necessary to create the rush of water designed to carry the participant/participants and their floatation device into the ride.

Preferably the pitch of the internal thread can be varied during the design and manufacture stage to compensate for variations in the angle of the ride itself. By varying the pitch it will be possible to create the optimum size of pond being held in the threads of the screw. Preferably the exit moulding will eject the participant/participants and their floatation device by raising the inside surface of the tube at the point of the last complete revolution of the threaded tube prior to exit. The moulded shape will raise the participant/participants and their floatation vehicle to a point, which is higher than the exit lip of the tube.

Preferably participants will be discharged into a receiving unit, which can be either a receiving pool, or another ride, or channel or a connection device allowing the participants to be positioned ready for onward transmission in the next section of the ride or to exit the ride altogether. Preferably the entire ride will be supported on a series of annular rings attached at locations externally and which will be located on roller guides acting as bearings.

Preferably the roller guides will act as bearings but could be attached to the power source thereby driving the rotation of the ride. The guides and the power source will be of sufficient dimension and power to turn the entire threaded tube complete with the operating volume of water and the rides participant/participants and their floatation devices.

Preferably the transportation of participants and their floatation devices in this way will greatly reduce if not eliminate the necessity for, and use of access stairways.

Preferably the use of lifts or hoists for the rider's floatation devices will also be eliminated or reduced as the device will be transported with the rider.

Preferably as water is being transported to the top of the ride within the ride itself, the necessity for and use of pumps and pipe work will be either eliminated or reduced.

Typically the ride would be manufactured using traditional moulding techniques, and using almost any practical material, the most economical material being glass reinforced plastic with a steel support system

For the reasons previously stated, it is a natural progression to create an exciting amusement ride system to transport participant/participants and their vehicles within the water-based amusement park.

The ride system may include an elevated/inclined system to transport participant/participants and their vehicles from a first position to second and subsequent positions. The transportation system may include, for example, directional fluid jets, revolving threaded tube/tubes system, entry collar, entry cone, transition module and exit ejector moulding, directional connectors for change from one tube system to another, annular support ring and wheeled track supports and drive mechanism. In some preferred embodiments of the system a support structure may include support for the main ride system and also the drive unit mounting together with entry channel and receiving unit for ride completion or onward transmission.

In some preferred embodiments of the system, an amusement ride system may include an area to accommodate a floating queue. The floating queue may be contained within a channel. The channel may hold water at a depth sufficient to allow a participant/s and their vehicle(s) to float within the channel. The floating queue may be coupled to a water ride such that a participant/s and their vehicles remain in the water while being transferred from the channel to the water ride. In some preferred embodiments, an amusement ride may form a pprtion 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 system, though referred to herein as a transportation system, would at least in preferred embodiments be an entertaining and enjoyable part of the water park experience.

In certain preferred embodiments, an amusement ride system may include a continuous water ride. Amusement ride systems may include a system of individual water rides connected together. The system may include two or more water rides connected together. In some preferred embodiments, an amusement ride system may include an elevation system to transport a participant from a first elevation to a second elevation. The first elevation may be at a different elevation level than a second elevation. The first elevation may include an exit point of a first water amusement ride. The second elevation may include an entry point of a second water amusement ride. In some preferred embodiments, a first and second elevation may include an exit and entry points of a single water amusement ride.

At least in preferred embodiments the present invention provides an elevated revolving tube with an internal thread capable of carrying participant/ participants and their vehicles floating in a pond created by the shape of the internal screw thread. The revolving ride, powered by a suitable power source, would be shaped specifically in the actual screw threads and at the point of entry and exit as described later. These design features facilitate ease of entry and exit, and ensure the ride operates both safely and efficiently. The ride would carry people from a lower water level to a higher water level thereby eliminating, or at least reducing the necessity for stairways, tyre hoisting devices, pumps and pipe-work. Viewed from a still yet further aspect, the present invention relates to a system for conveying a participant/participants and their floatation device from a source of water to other sources of water in an amusement park, comprising: a threaded tube to convey participant/participants and or participant vehicle, wherein the tube is located to adjoin a source of water and to other sources of water; and a motor device configured to rotate the threaded tube as required.

The system may further comprise one or more fluid jets positioned at least along a portion of the entry channel and other locations. The system may have fluid jets configured above, at, or below water level to assist the directional passage of the participant/participants. A plurality of fluid jets may be positioned at various locations from entry to exit so as to gain maximum effect. It is envisaged that the fluid would be water but could be any substance including air which is acceptable to/compatible with the overall operating system.

The system may comprise a second and possibly a multiple of rotating threaded tubes to convey participant/participants and their floatation devices wherein the second and subsequent rotating threaded tubes can be adjoined to other rides within the amusement park. Second and subsequent motor devices may be designed to rotate other parts of the ride.

The system may have a control system to control the speed of tube rotation which when used in conjunction/combination with the fluid jets function to adjust the rate of participant/participants throughput through at least a portion of the amusement park. The control system may be manually or at least partially if not entirely automated.

The rotation of the threaded tube may be adjusted to a speed, which controls the participant/participants throughput rate. Preferably, the system comprises an entry spacer collar configured to ensure only one participant/participants vehicle enters the rotating threaded tube at any one time. Whilst the use of multiple vehicles in each thread turn is possible it is envisaged that this would be impracticable.

The spacer collar can be positioned by rotation, at a point to gain maximum effect from its function prior to permanent fixing. The dimension of the spacer collar when fitted to the end of the rotating threaded tube is preferably equal to or more than the depth of water at the entry point.

A gap is preferably provided in the spacer collar sufficient to allow safe passage of the participant/participant in their respective vehicles. Preferably, the profile of the spacer collar presents a vertical or near vertical wall to the water, which will hold back the water until the gap in the collar is presented. The system preferably comprises a conical shaped device for reducing the overall diameter of the ride intended to provide an easier entry passage on rides where the diameter of the ride is considered to be too large for a more conventional entry style.

The system may further comprise a rotating tube with an internal thread, wherein the pitch of the thread is variable to suit the angle of tube installation; the angle between the pitch of the thread and the internal surface of the rotating tube should be such that it creates the optimum operating size for the pond of water therein contained.

The profile of the internal thread may be such that the base of the pond or pool formed will be flat and preferably is positioned substantially horizontally. This is desirable to both reduce the volume of water contained within the pond and to present a more user friendly surface in the event of the need for riders to stand away from their floatation devices.

The internal thread preferably remains open in its centre to allow a clear space both for exit of the participant/participants in the event of a breakdown and for visual effect, the hole created allowing a clear view through the centre of the rotating threaded tube.

The system preferably comprises an exit ejection thread located as a section of the final complete turn of thread within the rotating tube. The exit ejection thread may change in profile throughout the last complete turn, infilling the pond and lifting the participant/participants and their vehicle. Thus, the participant/participants and their vehicle may be lifted to a higher point than would be normally achieved if the thread had a uniform profile. The higher point of lift formed as part of the exit ejector thread is preferably as high/or higher than the water level contained in the first and subsequent receiving unit. The system may include an angled coupling. The angled coupling may be configured to allow one revolving threaded tube to discharge the participant/participants and their vehicle so that another threaded tube collects the participant/participants and their vehicle for onward transmission should it be required. The coupling may either be left hand or right hand or straight and may be varied in angle to suit site conditions and the angle required by the position of the revolving threaded tube being used for onward transmission.

The system may further comprise a support structure configured to provide support for the revolving threaded tube/ tubes and the revolving threaded tube movement mechanism; wheeled runners to provide a bearing system allowing free movement of the revolving threaded tube. The system may have annular rings affixed to the outer circumference of the revolving threaded tube at varying intervals throughout its length to provide a rotating track. A plurality of wheeled runners or bearings may be mounted to support the annular rings. The support structure may support the driving mechanism used to rotate the threaded tube. The driving mechanism may be powered by electricity, water, air, gas or hydraulics. The driving mechanism may be geared to allow variable speeds in forward and/όr reverse.

The water depth within the pitch of the internal thread is preferably sufficient to allow participant/participants vehicles to float where necessary and that the water should be at its minimum sufficient to act as a lubricant. The transport of participant/participants and their vehicles may be an inclined direction and a declined direction when the drive unit is reversed.

The first and subsequent sources of water may be a pool, a channel, or a waterslide.

The participant/participants preferably ride on a floatation device. The participant/participants may ride on an inflatable floatation device.

It will be appreciated that the entire ride, or a section of the ride can be themed to suit the requirements of the location and/or the client. The internal screw thread/or threads may be in-filled to exclude light allowing specialist internal lighting themes and effects.

DETAILED DESCRIPTION

The water ride relies on riders' vehicles entering one at a time and in such a way5 that a following rider cannot crowd or interfere with smooth safe entry.

The water ride when viewed as a side elevation is essentially a series of compartments each containing a pool of water. Although a ride could be constructed large enough to accommodate multiple users and vehicles in each compartment, it is envisaged for the time being that one floatation device would be sufficient in each0 compartment. For this reason, riders with their floatation devices should arrive at the starting point individually.

The present invention is designed to ensure that riders and their vehicles are presented individually and correctly spaced ready for entry into the water ride.

The present invention is a complete system for spacing riders ready for entry but5 usage of part or all of the system is dependant on throughput of the ride to be determined at the time and also the individual prevailing site conditions.

The entry to the ride is particularly hazardous if the end of the cylinder is simply submersed in the water of a normal pool at water level, as entry relies in part on the rider manoeuvring into the correct position. To this end it would be safer if the riders passage0 into the ride was involuntary or if aid was necessary then it should be minimal, the invention would act as a river with sides of a width to contain and guide only one rider or rider vehicle at a time into the entrance of the ride proper.

Amusement rides may include so called "water" amusement rides. Water amusement rides typically include water as an effect at least in some portion of the5 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 vehicles to float.

The ride now disclosed is in effect a revolving cylinder reinforced and mounted on supports as necessary and with an internal screw thread as depicted. Participants and their vehicles approach the bottom end of the ride via a channel or sjmilar formed deep enough for a vehicle and its riders to float. The vehicle and participants float towards the ride with the aid of the current created by the flow of water, in some cases it may be helpful for jets to be mounted as described, which would help propel and guide the participant/participants and their vehicles.

In the present embodiment it is essential that participants and their vehicles enter the ride one at a time as the pool of water created by the internal screw thread is designed to accept only one vehicle and its participants at a time. Therefore as the participant and his vehicle arrive at the start of the ride the entry collar will assist entry into the ride. The entry collar is in effect a barrier located at the entrance to the ride which is designed to hold back participant/participants and their floatation devices together with the flow of water in the approach channel until the gap in the collar is presented by the revolution of the ride. As the gap moves to the entry position water will rush in to the first thread taking the participant/participants and their floatation devices with it. As the ride revolves the gap will move above the water level restoring the barrier and holding back water and the next participant/s and their vehicle ready for the next complete revolution of the ride. It can be seen that in this way only one vehicle and its rider/s will be allowed to enter the ride in each complete revolution of the cylinder.

When a ride is constructed with a tube diameter great enough to accommodate multi user floatation devices it is envisaged that a conical moulding would be affixed to the entrance of the ride. The device would be large enough to encompass the entire diameter of the ride and would reduce the entry diameter to a dimension, which would accommodate the floatation devices more efficiently. It may be possible for more than one vehicle to enter the ride at a time but this would involve some modification to the ride as proposed.

At peak operating times it is envisaged that the ride will have a vehicle and participant/participants in each turn of the screw thread. The shape of the screw thread and. the angle of the ride will be variable at design and manufacture stage to suite site conditions and client requirements but it is envisaged that the floor of each thread will be horizontal, in this way not only will it reduce the amount of water required to operate the ride but will present a flat base on which a participant may stand should it be necessary for riders to climb out of the ride. But in any event, the pool of water created by each turn of the thread will be sufficient for participant/participants and their vehicles to float unhindered or in some cases it may be necessary to reduce the volume of water to a level where it acts as a lubricant only.

As the ride revolves participants and their vehicles move on the body of water towards the upper end of the ride and this process continues to the point where the participant/participants and their vehicles are ready for discharge or exit from the ride itself.

The exit or ejector section included in the design of the ride eηsure that the participant/participants and their floatation devices are able to exit the ride quickly and safely by creating a 'mini slide' within the last complete revolution of the ride. As the ride turns, the rider is lifted by virtue of the changing profile of the base of the ride to a point above the exit lip of the tube and this effectively allows the rider/s to slip down and out into the collection device away from the rides natural exit point.

Because of the size of the proposed ride, the use of a steel support system may become necessary but this can be established at manufacture stage to suit site conditions.

Attached to the outer surface of the ride would be a single or series of annular rings. These rings would be mounted on a series of roller bearings designed to support the entire ride as it revolves about its axis. It is envisaged that the bearings would be established at manufacture stage to suit site conditions. A suitable drive unit is necessary to turn the ride about its axis and this can be established at manufacture stage to suit site conditions. It is envisaged that the drive unit would have variable control speeds and also be reversible should it become necessary to use the ride in reverse.

A water ride 1 in accordance with a preferred embodiment of the present invention is shown in the accompanying Figures. The water ride 1 may be installed in an amusement or theme park to convey users 3 seated in a floatation vehicle 5. In the present embodiment, the individuals 3 are transported from a water pool P onto a water slide S.

The water ride 1 comprises a cylinder 7 which is rotatable about a longitudinal axis X. The cylinder 7 has an inlet 9, an outlet 11 and an internal thread 13 for conveying the individuals 3 from the inlet 9 to the outlet 11. The cylinder 7 is inclined such that the inlet 9 is partially submerged in the water pool P. An overflow/balance tank T is provided for collecting water below the pool P.

The cylinder 7 is preferably made of glass fibre and is mounted on a steel support structure 15. The cylinder 7 is mounted on a set of bearings 16 and a motor 17 is provided to drivingly rotate the cylinder 7.

The cylinder 7 comprises a sidewall 19 defining the internal thread 13 and an inlet cone moulding 20. The region of the sidewall 19 extending axially between the internal thread 13 forms a helical platform on which each floatation vehicle 5 is supported as it is conveyed from the inlet 9 to the outlet 11. The section of the sidewall defining said platform is inclined relative to the longitudinal axis X such that the platform is substantially horizontal when positioned at the bottom of the cylinder 7. This arrangement is desirable since it reduces the volume of water transported by the internal thread 13.

An inlet collar 21 is provided at the inlet 9 for controlling the flow of water into the cylinder 7. As shown in Figure 5, the inlet collar 21 extends only partway around the circumference of the cylinder 7 and defines an aperture 23 for enabling the introduction of the floatation vehicle 5 into the cylinder 7. The cylinder 7 rotates in a clockwise direction when viewed from reference point B.

The inlet collar 21 has a leading edge 25 and a trailing edge 27. The leading edge 25 displaces any floatation vehicle 5 located in the inlet 9 without tipping it over as the cylinder 7 rotates. The trailing edge 27 causes a surge of water into the inlet 9 when the trailing edge 27 enters the pool P (i.e. when the aperture 23 is introduced into the pool P). Advantageously, the surge of water into the inlet 9 draws a floatation vehicle 5 along with its occupant(s) into the cylinder 7. The continued rotation of the cylinder 7 causes the internal thread 13 to convey the floatation vehicle 5 towards the outlet 9 in known manner. One or more directional flow jets (not shown) may be provided in an entry channel housing to assist entry of the vehicle 5 into the inlet 9.

The outlet 11 of the cylinder 7 will now be described with reference to Figures 6 to 10. The outlet 11 is coupled to the slide S so that an floatation vehicle 5 is launched directly onto the slide S, as shown in Figure 6. The profile of the sidewall 19 is modified such that a region proximal the outlet 11 has a reduced diameter relative to circumferentially adjacent sections so as to form a raised outlet ramp R. Thus, the platform on which the floatation vehicle 5 is supported rises as the vehicle 5 approaches its exit position. As shown in Figures 9 and 10, the vehicle 5 is expelled from its raised position directly onto the slide S. It will be noted that the internal thread 13 is adapted to retain the vehicle 5 and water in the cylinder 7 until the vehicle 5 is in the desired position. The taper of the internal thread 13 is coincident with the reduced diameter of the region proximal the outlet such that the water is allowed to exit the cylinder 7 when it has been raised to its highest level.

The operation of the water ride 1 will now be described with reference to the accompanying Figures. In particular, the introduction of a vehicle 5 into the inlet 9 will be described with reference to Figures 1 to 4; and the expulsion of a vehicle 5 from the outlet 11 will be described with reference to Figures 6 to 10.

Figure 1 shows the vehicle 5 and the riders moving forward into a riding position. The aperture 23 in the entry collar 21 is located in the pool P and is in position to allow the vehicle 5, the riders and water to rush into the first thread in the cylinder 7. The surge of water into the inlet 9 also draws the next vehicle 5' into position in the pool P ready to be drawn into the inlet 9 when the cylinder 7 undergoes one complete rotation.

The cylinder 7 is shown in Figure 2 having undergone a quarter revolution from the position in Figure 1. The continued rotation of the cylinder 7 starts to move the aperture 23 out of the pool P and the collar 21 thereby forms a barrier limiting or preventing the introduction of further water into the cylinder 7. As outlined above, the trailing edge 27 of the collar 21 guides the vehicle 5 into the cylinder 7 without tipped the vehicle 5. The collar 21 also prevents the next vehicle 5' from entering the inlet 9 and helps move it into position ready for introduction into the inlet 9 once the cylinder 7 has undergone a complete revolution.

The cylinder 7 is shown in Figure 3 having undergone a half turn from the position in Figure 1. The rotation of the cylinder 7 causes the vehicle 5 to start to ascend the ride 1 floating in its own pond (or pool) of water. The next vehicle 5' has reached the entry collar and is awaiting the next revolution of the ride to enable entry when the aperture 23 again enters the pool P. The cone moulding 20 and entry collar 21 have now turned and closed off entry to ride holding back water and riders. Moreover, the following vehicle 5" has at this stage started to move towards the start position proximal the inlet 9.

The cylinder 7 is shown in Figure 4 having undergone a three-quarter turn from the position in Figure 1. The vehicle 5 remains floating in its own pool of water defined by the internal thread 13 and the continued rotation of the cylinder 7 has caused the vehicle 5 to be raised above the level of the water in the pool P. The next vehicle 5' is preparing for entry into the cylinder 7 through the aperture 23. The cone moulding 20 and the inlet collar 21 are in a fully extended position and serve as a barrier preventing the next vehicle 5' and the water in the pool P entering the cylinder 7. Once the cylinder 7 has undergone one complete revolution, the aperture 23 is again positioned in the pool P and the next vehicle 5' is drawn into the cylinder 7 via the inlet 9. It will be appreciated that this cycle is repeated as the cylinder 7 continues to rotate.

An end elevation of the outlet 11 from the water ride 1 is shown in Figure 6. The cylinder 7 is shown in an exit position with a vehicle 5 having been expelled onto the slide S. The final thread of the internal thread 13 serving to eject the vehicle 5 from the cylinder

7.

A side elevation of the outlet 11 is shown in Figure 7. In this Figure the vehicle 5 in the final thread of the internal thread 13 is approaching the outlet 11. Similarly, the second and third vehicle 5', 5" in the series are each proceeding towards the outlet 11. The vehicles 5 are each in respective pools of water defined by the internal thread 13. The cylinder 7 is shown in Figure 8 having undergone a quarter turn from the position in Figure 7. The first vehicle 5 is shown at the point just before the exit proximal the outlet. However, the internal thread 13 maintains the vehicle 5 within the cylinder 7 in its own pool of water. The profile of the sidewall 19 of the cylinder 7 is adapted so as to start to raise the vehicle 5 in a substantially radial direction when the cylinder 7 is approximately 90-180° from its final expulsion position.

The cylinder 7 is shown in Figure 9 having undergone a half turn from the position in Figure 7. The floor or base of the final thread is beginning to lift to a height above normal (i.e. closer to the longitudinal axis X of the cylinder 7 than the preceding section(s) of the cylinder 7) and which will eject the vehicle 5 and water contained in the final turn of the thread. The sidewall 19 is profiled to define an inclined section R sloping downwardly onto the slide S.

The cylinder 7 is shown in Figure 10 having undergone a three-quarter turn from the position in Figure 7. The sidewall 19 forming the base proximal the outlet 11 slopes downwardly from the final thread causing the vehicle 5 to be discharged from the cylinder

7 onto the slide S. The second and third vehicle 5', 5" continue to progress towards the outlet 11 as^'the cylinder 7 rotates.

While the invention is susceptible to various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawings and the accompanying description. 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. It will be appreciated that various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention. For example, a plurality of the cylinders 7 described herein could be chained together. Adjacent cylinders 7 in the chain could be linked by a coupling. Alternatively, the vehicle 5 could be deposited from a first cylinder 7 into an intermediate pool prior to entering a second cylinder 7.

Moreover, although the preferred embodiment shows vehicle 5 being transported between different levels, it is envisaged that the present invention could be used to transport vehicle from a first pool P to a second pool P' at substantially the same level.
