Abstract

A water or other amusement or surfing attraction that includes an inflatable portion or material. A variety of different waveforms, such as curling waves, may be generated. The inflatable portion or material may be inflated to different pressures, or multiple inflatable portions or materials may be coupled with the attraction such that the shape of a riding surface can be manipulated by modifying the amount of air or fluid used to inflate the inflatable portions or materials. Contouring elements that exhibit a force upon a sliding surface of an attraction may be used to form a desired contour in the sliding surface. Various riding configurations may be used as part of the attraction, including sidewalls that taper inward or flare outward, bowl-shaped riding surfaces, and half-bowl-shaped riding surfaces. Staircases that are inflatable or non-inflatable may be used as entry and/or exit points for riders to interact with the riding surfaces.

Description

INFLATABLE WATER ATTRACTION
BACKGROUND
1. Field The present invention relates generally to water attractions, such as wave machines or surfing simulators. More particularly, the present invention relates to amusement or water attractions that incorporate one or more inflatable areas or portions.

2. Description of the Related Art Water attractions (e.g., waterslides, surfing slides or machines, boogie-boarding slides, etc.) are a popular entertainment activity during periods of warm weather. Conventional water attractions are commonly made of fiberglass or other rigid or semi-rigid materials that provide a smooth and slippery surface for supporting a flow of water thereon to transport a rider from an entrance to an eat. A variety of different types of ride vehicles (e.g., inner tubes, body boards, surf boards, floatation devices, etc.) may be used by the rider when the rider travels along the water attraction by supporting the rider as the ride vehicle slides along the sliding surface.
Maintaining low friction between the rider (or a ride vehicle that the rider rides upon) and the sliding surface that supports the flow of water helps ensure an exciting or thrilling ride since the lower the friction on the sliding surface of the water attraction, typically the greater the speed that the rider may achieve. Lower friction between the rider and the sliding surface can also increase the comfort of the rider since it aids in preventing undesirable rubbing on the rider's skin or tugging at the rider's swimsuit. When using a ride vehicle, low friction can also aid in lengthening the life of the ride vehicle and the water attraction due to reduced wear and tear to each of the ride vehicle and the water attraction as the ride vehicle travels down the water attraction, which can reduce maintenance or install costs.
One type of water attraction that has proven a popular lure for patrons to water or other amusement parks or venues is the surfing machine or simulator. These machines may be used both for entertainment purposes as well as training purposes for helping instruct individuals that may be wary or otherwise unable to surf out in the open ocean. Conventional surf machines utilize water pumps cooperating with nozzles or jets to flow a sheet or layer of water over a variety of surfaces and allow riders to skim atop the water flow. A sliding surface of the surf machines is conventionally a rigid or semi-rigid, low-friction surface that supports maneuvering by riders upon a conventional or modified surfboard or boogie board (individually and collectively referred to as a "board").
Unfortunately, users without much surfing experience, either in the ocean or upon surfing machines, commonly fall off of the board during early attempts at using surfing machines. The surfaces of these machines make uncomfortable contact with a rider upon the rider's falling off of their board.
Moreover, the risk of falling while walking on conventional surf machines (e.g., when entering or exiting the portion of the ride to be surfed upon) is heightened since the surfing machine surface must commonly be manufactured to be slippery in order to adequately allow for low-friction between a rider's board and the surface of the ride.
As the sheet flow or standing wave product (collectively "surfing machine") market becomes more popular, water venues increasingly look to new surfing machines that can provide novel experiences to riders. Moreover, as the surfing industry becomes more sophisticated and the influence of extreme sports becomes more popular, more extreme standing waves created by such surfing machines is desired in order to satisfy the thrill anticipated by these new generation of users, both adults and children. As new surfing machines are developed, particularly those with more extreme characteristics, safety concerns, manoeuvrability, and rider comfort must be adequately addressed.
Thus, an improved water attraction configured to allow for various kinds of waveforms, to help ensure rider safety, to reduce rider discomfort, and/or to improve rider maneuverability is desired. Ideally, the water attraction would allow a rider to make contact with the surface of the water attraction, for example, upon falling off of a ride vehicle, with reduced risk of injury or discomfort. Moreover, the water attraction would ideally permit improved control, either by the rider themselves, or by the ride designer, over the speed, location, orientation, or other maneuverability characteristic as the rider uses the water attraction.

DETAILED DESCRIPTION
The detailed description of exemplary embodiments herein makes reference to the accompanying drawings and pictures, which show the exemplary embodiments by way of illustration and its best mode. While these exemplary embodiments are described in sufficient detail to enable those skilled in the art to practice the invention, it should be understood that other embodiments may be realized and that logical and mechanical changes may be made without departing from the spirit and scope of the invention. Thus, the detailed description herein is presented for purposes of illustration only and not of limitation. For example, the steps recited in any of the method or process descriptions may be executed in any order and are not limited to the order presented. Moreover, any of the functions or steps may be outsourced to or performed by one or more third parties. Furthermore, any reference to singular includes plural embodiments, and any reference to more than one component may include a singular embodiment.
Turning first to FIG. 1 a perspective view of a water attraction 100 is shown that incorporates inflatable areas or materials. The water attraction 100 is formed of a structure that utilizes one or more inflatable elements (e.g., walls 140, 142). The inflatable elements may be walls, for example, as shown, that are configured to couple with one another andfor to other components of the water attraction 100 in order to form a stable base capable of supporting a flow of water upon certain surfaces of the water attraction 100. A rider may therefore ride or surf upon such surfaces, as discussed in greater detail herein. A coating may be sprayed, painted, or otherwise applied to a surface of the inflatable elements or non-inflatable elements of the water attraction 100, for example, to vary the smoothness or frictional coefficient of the underlying elements, as desired.
As illustrated, a source of water, such as one or more nozzles or jets 130 are connected at one end of the water attraction 100 and are configured to spray, flow, or otherwise provide a volume or flow 135 of water upon certain surfaces of the water attraction 100. For example, a first surface 101 disposed immediately adjacent to the nozzles or jets 130 may be substantially planar in nature. A second surface 102 may be disposed at a tilted or inclined orientation (e.g., curved or planar) and coupled with the first surface 101, with a lower elevation disposed closer to the nozzles or jets 130. In one embodiment, the first surface 101 and the second surface 102 may be formed of the same material or same component. In an alternative embodiment, the first surface 101 and the second surface 102 may be made of different materials or components.
A third surface 104 is connected with the second surface 102 and allows for water to be drained from the third surface 104 (e.g., via a grating, grille, mesh, etc. or other porous configuration or material making up the third surface 104).
Thus, the flow of water from the nozzles 130 flows onto the first surface 101, then onto the second surface 102, and finally onto the third surface 104 where the water is drained to a water reservoir 110 located, for example, underneath the first surface 101, the second surface 102, and/or the third surface 104.
One or more lower dewatering surfaces 105 and/or 105 may be positioned adjacent to the nozzles 130 and/or at lower elevation surfaces, for example, to drain water from the water attraction 100 when the water attraction is not powered or operating.
=
A plant room 115 for containing mechanical and/or electrical components that interface with the nozzles 130 is disposed adjacent to the nozzles 130. For example, a pump 145 may communicate with water in the water reservoir 110 and may be configured to pump at least some of the water in the water reservoir 110 back to the nozzles 130 so that the water can be recirculated and flow again over the first, second, and third surfaces (101, 102, 104). The plant room 115 may be designed as a permanent structure, or may be a temporary structure (e.g., an inflatable and/or a mobile fiberglass structure) that is configured to be transported as part of a mobile water attraction. In some embodiments, the plant room 115 may feature an integrated or built in nozzle for the flowing of water onto the first, second, and/or third surfaces (101, 102, 104). Thus, in one embodiment, the water attraction 100 may be an inflatable standing wave ride that is connected to a separate fiberglass pump and/or plant room. In another embodiment, a pump may be located within a portion or area of the waterslide attraction 100, for example, within the water reservoir, for the purposes of water recirculation.
A staircase 150 is positioned on one side of the water attraction 100 and extends from a ground level to the third surface 104 for allowing entry and/or exit access for riders wishing to use the water attraction 100. In an alternative embodiment, different locations along the water attraction 100 for a staircase may be used (e.g., alternative sides of the ride) and/or multiple staircases may be used (e.g., two staircases, one on each side of the ride). The staircase 150 includes steps 152 and side rails 164. The side rails 154 may help ensure safety of riders using the steps 152 so that they do not fall off of the staircase 150 in the case of a loss of footing. Either or both of the steps 152 and/or side rails 154 may be inflatable. Similarly, perimeter protection bumpers 120 or other handrails, guardrails, footholds, handholds, etc. may be disposed along an outer edge of the water attraction 100 (or at other locations along its surfaces) for increased safety and/or containment of riders and/or water flowing on the water attraction 100. In one embodiment, the perimeter protection bumpers 120 may be inflatable.
In one embodiment, one or more inflatable elements of the water attraction 100 may be inflated to differing pressures in order to raise/lower or otherwise adjust a shape of a wave formed by the flow of water upon its surfaces (e.g., the second surface 102). For example, the second surface 102 may be a fabric, sheet or other material that is stretched (e.g., tensioned) or positioned over one or more inflatable elements (e.g., bladders) located beneath the second surface 102. In another embodiment, the inflatable elements may be formed integrally as part of the second surface 102. In such an embodiment, a rider may ride upon the inflatable or other contouring elements themselves (e.g., if the inflatable or other contouring elements are positioned on a top side of the sliding surface). Alternatively, an integrally formed inflatable or contouring element may be contained within an interior area of a fabric, sheet, or other material that is used for the second surface 102.
As certain of those inflatable elements are inflated or the pressures of certain of those inflatable elements are adjusted, the shape of the second surface 102 may be modified as the inflatable elements act to raise or otherwise adjust the shape of the second surface 102. When water flows over the second surface 102, the shape of the second surface 102 may cause the water to form different types of wave shapes (e.g., curling waves to the left or to the right, barreling waves to the left or to the right, etc.).
In another embodiment, one or more inflatable elements of the water attraction 100 may be inflated to differing pressures in order to maintain stability of the water attraction 100 while also providing safe and/or comfortable impact surfaces for riders (e.g., riders that fall off of their board or other ride vehicle). For example, impact or riding areas of the water attraction 100 may have the one or more inflatable elements in or associated with those areas inflated to a lower pressure while access and/or structural areas of the water attraction 100 may have the one or more inflatable elements in or associated with those areas inflated to a higher pressure. In another embodiment, one or more of the first surface 101, the second surface 102, and/or the third surface 104 may have an adjustable gradient for the riding slope. For example, such a configuration may be used to direct water flow in a particular direction from a higher slope elevation to a lower slope elevation.
FIG. 1B shows one exemplary method or manner of obtaining a desired waveform or shape on the water attraction 100 of FIG 1A_ An inflatable portion or bladder 160 is disposed on or otherwise coupled with (e.g., located beneath) the second surface 102 of the water attraction 100_ As increased amount of air or other fluid is provided to or in the bladder 160, the bladder 160 inflates and presses against the second surface 102, causing the second surface 102 to extend upward in a predetermined shape. For example, the concave portion 162 of the bladder 160 may form a curling wave when a flow of water flows 164 across the second surface 102. Any of a variety of shapes may be formed via bladders coupled with the second surface 102 in an alternative embodiment In one example, the bladder 160 may extend to the full width and/or length of the sliding surface 102 and/or the water attraction 100. Certain embodiments may utilize additional inflatable elements configured to be positioned below and/or secured on top of the second surface 102 in order to generate a desired wave shape.

FIG. 1C shows another exemplary method of obtaining a desired waveform or shape on the water attraction 100. A plurality of inflatable portions or bladders 170 are disposed on or otherwise coupled with (e.g., located beneath) the second surface 102 of the water attraction 100. Similar to the discussion above, one or more of the inflatable portions or bladders 170 may be inflated so as to direct the flow of water that flows 164 across the second surface 102 in a desired or predetermined direction, thus creating waves having a certain shape or configuration. In addition or in the alternative, the bladders 170 may be manipulated so as to control the flow of water without changing a shape of a wave to be ridden by a rider (e.g., certain bladders 170 may be inflated in order to direct the flow of water to a drainage area).
FIG. 2 shows a perspective view of a water attraction 200 that generates a curling wave 210 that may be ridden or otherwise interacted with by a rider.
The water attraction 200 may include features that are the same as or similar to those previously discussed. Thus, the water attraction 200 may utilize inflatable elements or portions and/or coatings for achieving a desired frictional coefficient such that a rider can tide upon a flow of water upon a sliding surface 202 and surf on or in a part of the curling wave 210. Any of a variety of wave shapes or types may be generated in an alternative embodiment. In an 'alternative embodiment, multiple waves (e.g., curling waves) may be generated upon a sliding surface of a water attraction.
FIG. 3 shows a perspective view of a water attraction 300 with curved sidewalls that taper from a front end 360 to a rear and 370 of the water attraction 300. The water attraction 300 may include features that are the same as or similar to those previously discussed. Thus, the water attraction 300 may utilize inflatable elements or portions and/or coatings for achieving a desired frictional coefficient such that a rider can ride upon a flow of water upon a sliding surface 310.
A first curved sidewall 320 is disposed along a first edge of the sliding surface 310. A second curved sidewall 322 is disposed along a second and opposite edge of the sliding surface 310. A flow of water 340 is provided onto the sliding surface 310 by one or more nozzles 350 or other jets. After flowing over the sliding surface, the flow of water may drain through a drainage surface or portion 330, the same as or similar to the previous discussion. In certain embodiments, additional drainage surfaces or portions 332 and/or 334, located at a top of each of the curved sidewalls 320 and/or 322 may be used. A rider may slide or surf upon the sliding surface 310 on the flow of water 340 and also slide or carve up all or a portion of the first curved sidewall 320 and/or the second curved sidewall 322. Although the sidewalls (320, 322) are shown in a tapered configuration from the front end 360 to the rear end 370 of the water attraction 300, in an alternative embodiment, the sidewalls (320, 322) may not taper and instead may be parallel or substantially parallel to one another or be oriented in a different configuration.
Similar to FIG. 3, a perspective view of a water attraction 400 is shown in FIG.
4. However, the water attraction 400 is shown with curved sidewalls that flare from a front end 460 to a rear end 470. The water attraction 400 may include features that are the same as or similar to those previously discussed. Thus, the water attraction 400 may utilize inflatable elements or portions and/or coatings for achieving a desired frictional coefficient such that a rider can ride upon a flow of water upon a sliding surface 410.
A first curved sidewall 420 is disposed along a first edge of the sliding surface 410. A second curved sidewall 422 is disposed along a second and opposite edge of the sliding surface 410_ A flow of water 440 is provided onto the sliding surface 410 by one or more nozzles 450 or other jets. In certain embodiments, additional or alternative nozzles or jets may be placed in other locations of the water attraction 400, for example, atop or beneath one or both of the curved sidewalls (420, 422) and directed onto one of both of the curved sidewalls (420, 422) in order to better wet the surfaces of the curved sidewalls (420, 422). After flowing over the sliding surface 410, the flow of water may drain through a drainage surface or portion 430, the same as or similar to the previous discussion. Similar to previously discussed, in certain embodiments, additional drainage surfaces or portions 432 and/or 434, located at a top of each of the curved sidewalls 420 and/or 422 may be used. A rider may slide or surf upon the sliding surface 410 upon the flow of water 440 and also slide or carve up all or a portion of the first curved sidewall 420 and/or the second curved sidewall 422. Although the sidewalls (420, 422) are shown in a flared configuration from the front end 460 to the rear end 470 of the water attraction 400, in an alternative embodiment, the sidewalls (420, 422) may not flare and instead may be parallel or substantially parallel to one another or be oriented in a different configuration.
Turning next to FIG. 5, a water attraction 500 is shown from a top perspective.
The water attraction 500 may include features that are the same as or similar to those previously discussed. For example, the water attraction 500 may include inflatable portions or elements that can be inflated to provide a riding surface or that can be inflated to provide a stable base or structure for coupling with a riding surface, such as a fabric sheet (e.g., flexible and/or with a low coefficient of friction), for enabling surfing or other riding by a rider.
The water attraction 500 is formed in the shape of a bowl. At a center area of the bowl is a plurality of nozzles 604 configured in a radial orientation such that they are capable of spraying or flowing 506 water in substantially 360 degrees. In an alternative embodiment, the plurality of nozzles 504 may be a single nozzle and/or may be capable of flowing water in less than 360 degrees. A sliding surface 502 in the shape of a bowl is positioned adjacent to the plurality of nozzles 504. Thus, similar to previous embodiments, a rider may ride upon a flow of water from the plurality of nozzles 504 that flows over the sliding surface 502, thus surfing or skimming on the water along an interior surface of the bowl shape. The bowl shape may allow for greater numbers of riders to concurrently use the water attract1on500.
A drainage surface 510 is positioned adjacent to the sliding surface 502. In an exemplary embodiment, the drainage surface is coupled with or otherwise meets with an upper edge of the sliding surface 502 such that the flow of water from the plurality of nozzles 504 travels onto the drainage surface 510 after flowing over the sliding surface 502. Thus, the water flowed 506 from t the plurality of nozzles 504 flows first onto the sliding surface 502 in a direction towards the drainage surface 510. When the water encounters the drainage surface 510, the water is drained to a water reservoir, for example, a tank or volume of space positioned beneath the drainage surface. In one embodiment, the water reservoir may be disposed around at least part of a perimeter of the bowl shape formed by the sliding surface 502. In an alternative embodiment, the water reservoir may be of any shape and located at any of a variety of positions, for example, interfacing with the water drained through the drainage surface 510 via a piping system to transport the water.
The same or similar methods or manners previously discussed, utilizing pumps, motors, and/or other mechanical and/or electrical equipment, may be used for pumping or otherwise recirculating the water in the water reservoir back to the plurality of nozzles 504 so that it can be reused and flowed again over the sliding surface 502. Riders may enter upon the sliding surface 502 of the water attraction 500 via the drainage surface 510 or, in an alternative embodiment, another path, entrance, or exit means may be provided (e.g., a staircase may extend to a center of the bowl from outside the bowl, a portion of the bowl may be cut-away to allow riders to enter into the center of the bowl, etc.).
FIG. 6 shows a water attraction 600 in the form of a half-bowl from a top view.
The water attraction 600 may include features that are the same as or similar to those previously discussed. For example, the water attraction 600 may include inflatable portions or elements that can be inflated to provide a riding surface or that can be inflated to provide a stable base or structure for coupling with a riding surface, such as a fabric sheet with a low coefficient of friction, for enabling surfing or other riding by a rider.
The water attraction 600 is formed in the shape of a half-bowl. At a lower area or position of the half-bowl is a plurality of nozzles 604 configured in a radial orientation such that they are capable of spraying or flowing 606 water in an outward direction onto the half-bowl shape (e.g., substantially 180 degrees)_ In an alternative embodiment the plurality of nozzles 604 may be a single nozzle and/or may be capable of flowing water in less than or greater than 180 degrees. A sliding surface 602 in the shape of a half-bowl is positioned adjacent to the plurality of nozzles 604. Thus, similar to previous embodiments, a rider may ride upon a flow of water from the plurality of nozzles 604 that flows over the sliding surface 602, thus surfing or skimming on the water along an interior surface of the half-bowl shape.
A drainage surface 610 is positioned adjacent to the sliding surface 602. In an exemplary embodiment, the drainage surface is coupled with or otherwise meets with an upper edge of the sliding surface 602 such that the flow of water from the plurality of nozzles 604 travels onto the drainage surface 610 after flowing over the sliding surface 602. Thus, the water flowed 606 from the plurality of nozzles 604 flows first onto the sliding surface 602 in a direction towards the drainage surface 610. When the water encounters the drainage surface 610, the water is drained to a water reservoir, for example, a tank or volume of space positioned beneath the drainage surface 610. In one embodiment, the water reservoir may be disposed around at least part of a perimeter of the half-bowl shape formed by the sliding surface 602. In an alternative embodiment, the water reservoir may be of any shape and located at any of a variety of positions, for example, interfacing with the water drained through the drainage surface 610 via a piping system to transport the water.
The same or similar methods or manners previously discussed, utilizing pumps, motors, and/or other mechanical and/or electrical equipment, may be used for pumping or otherwise recirculating the water in the water reservoir back to the plurality of nozzles 604 so That it can be reused and flowed again over the sliding surface 602. Riders may enter upon the sliding surface 602 of the water attraction 600 via the drainage surface 610 or, in an alternative embodiment, other entrance means may be provided (e.g., riders may enter the sliding surface 602 from a side of the half-bowl shape without having to first step onto the drainage surface 610).
FIG. 7A shows a side view of an inflatable water attraction 700 utilizing a connected plantroom or equipment room. The water attraction 700 may include features that are the same as or similar to those previously discussed.
The water attraction 700 has an inflatable base 702 upon which a sliding surface 706 is integral or attached thereto. A rider may surf or otherwise slide, either with or without a ride vehicle, upon a flow of water directed upon the sliding surface 706. Similar to embodiments previously discussed, a drainage or dewatering area 708 is integral with the inflatable base 702 or is attached or formed thereon (e.g., via mesh, grating, grilles, etc.) and allows the flow of water to drain through the drainage or dewatering area 708 after the flow of water has travelled across the sliding surface 706 into a water reservoir 710. As illustrated, the water reservoir 710 may be located beneath the sliding surface 706 and/or drainage or dewatering area 708 and contained by at least a part of the inflatable base 702.
The inflatable base 702 includes a first set of a plurality of fixings 720 disposed along a surface of the inflatable base 702 (e.g., an underside) and are configured to attach or otherwise couple with a ground or floor surface to help maintain stability for the water attraction 700. A separate plantroom 730 is located adjacent to the inflatable base 702 for the containment of various pieces of equipment used for proper operation of the water attraction 700 (e.g., filtration units, dosing units, controls, pumps, air blowers, nozzles, etc.).
A second set of a plurality of fixings 722 are disposed on the plantroom 730 and/or on the inflatable base 702 for connecting the inflatable base 702 to the plantroom 730. In one embodiment, securing the inflatable base 702 to the plantroom 730 (e.g., a heavier structure) may help keep the inflatable base 702 in a desired position, for example, during erection, during times when it is empty of water (such as during inspection or servicing), and/or when the inflatable base 702 is otherwise deflated of air or fluid.
The plantroom 730 includes a variety of pieces of equipment therein. For example, one or more pumps 750 is provided for pumping water from the water reservoir 710 to one or more nozzles 740. A section inlet 780 may be provided within the water reservoir 710 and connected with the one or more pumps 750. The suction inlet 780 may be positioned near the ground or floor such that water is enabled to be pumped from the bottom of the water reservoir 710. The one or more nozzles 740 is connected with the suction inlet 780 and/or the one or more pumps 760 via a filtration unit and/or dosing unit and/or manifold 770. The one or more nozzles 740 are directly connected with the inflatable base 702 and are configured to spray water received from the water reservoir 710 back onto the sliding surface 706 of the water attraction 700. In certain embodiments, the plantroom 730 may also include equipment for inflating one or more of the inflatable portions or surfaces of the water attraction 700 (e.g., air blowers).
FIG. 7B shows a side view of an inflatable water attraction 780. The water attraction 780 has a base or structure 782 (e.g., inflatable) that forms or supports a sliding surface 781 for a rider to ride or surf thereon and a dewatering area 783- for draining water into a water reservoir 784 located beneath the sliding surface 781 and/or the dewatering area 783. The water attraction 780 may include features that are the same as or similar to those previously discussed, for example, in FIG. 7A. However, the water attraction 780 utilizes a submerged pump 786, located at least partially within the water reservoir 784 for pumping water from the water reservoir 784 to one or more nozzles 792. The one or more nozzles 792 and associated piping or plumbing may be located within a nozzle area 790 (e.g., a connected plant room or equipment room). The nozzle area 790 may be a dry or wet area.
The one or more nozzles 792 may be directly connected with the base or structure 782 and are configured to spray water received from the water reservoir 784 back onto the sliding surface 781 of the water attraction 780.
FIG. 8A shows a side view of an inflatable water attraction 800 with a variable ride surface and constant positioned dewatering area. The water attraction 800 may include features that are the same as or similar to those previously discussed. The water attraction 800 has an inflatable base 802 that forms or supports a riding surface 804. A flow of water 810 (e.g., from nozzles, jets, a sluice, gravity, etc.) flows over the riding surface 804 and is evacuated at a dewatering area 806 by draining 820 into a water reservoir located beneath the riding surface 804 and/or the dewatering area 806.
The riding surface 804 may be adjustable or variable, for example, to generate larger or smaller waves and/or a steeper surfing or riding portion.
In one embodiment, the riding surface 804 may be varied via the use of inflatable bladders positioned underneath the riding surface 804. Likewise, any other type of contouring element may be (inflatable or not) to vary the riding surface 804 (e.g., hydraulic elements, etc.). A first riding surface configuration 830 (e.g., a beginner configuration) may provide a rider with a low-elevation and easier surface to surf thereon. A second riding surface configuration 832 (e.g., a general use configuration) may provide a rider with a medium-elevation surface to surf thereon. A third riding surface configuration 834 (e.g., an expert configuration) may provide a rider with a steep-elevation surface to surf thereon. For each of the above-described configurations, the dewatering area 806 does not adjust in elevation.
Different wave forms or shapes may be generated on any of the above-described configurations (e.g., the third riding surface configuration 834 may incorporate tube or barreling waves). In an alternative embodiment, greater or fewer variations to the riding surface 804 may be obtained FIG. 85 shows a side view of a portion of a riding surface 870 of an inflatable water attraction 850 with a variable ride surface and variable dewatering area.
The same as or similar to the above description for FIG. 8A, the riding surface 870 may be configured to be in a first riding configuration 860 (e.g., a beginner configuration), a second riding configuration 862 (e.g., a general use configuration), and a third riding configuration 864 (e.g., an expert configuration). However, in FIG. 8B, a dewatering area 880 is configured to also adjust in elevation depending upon the configuration of the riding surface 870. For example, the dewatering area 880 may be at a lowest elevation when the riding surface 870 is in the first riding configuration 860, a middle elevation when the riding surface 870 is in the second riding configuration 862, and a highest elevation when the riding surface 870 is in the third riding configuration 864. Similar to the above, different wave forms or shapes may be generated on any of the above-described configurations and/or greater or fewer variations to the riding surface 870 may be obtained in alternative embodiments.
Although the embodiments shown and described above feature water attractions having particular configurations or shapes, an inflatable portion and/or coating applied to the inflatable portion may be implemented on any of a variety of water or other attractions. In one example, entry and/or exit locations for a water ride may differ from those explicitly shown in the embodiments illustrated. In another example, a water attraction, such as a curling wave surfing ride, may have its entire main structure or sliding surface as an inflatable structure or made from an inflatable material. Alternatively, a water attraction, such as a curling wave surfing ride, may only be constructed with partially inflatable structures (e.g., at the entry and exit points and/or the sliding surface or riding area). In dewatering or drainage areas of a water attraction, such as at the exit points, an integral netting or grating may be used in place of, or in conjunction with, the inflatable materials at those locations.
The inflatable portion or portions may be adjusted to different pressures and/or different inflation amounts in order to achieve a variety of different wave forms or riding surface shapes or configurations. Moreover, alternative embodiments may have certain inflatable portions filled to greater pressures or amounts to aid in stability of the ride while other inflatable portions are filled to lower pressures or amounts to aid in providing a comfortable surface for riders to make contact with, for example, when such riders fall or lose their footing. Still other embodiments may utilize contouring elements or portions that exhibit a force on a sliding surface in similar fashion to the described ' inflatable embodiments, but may utilize hydraulic or other moving components, as previously discussed. Any of a variety of coatings may be applied to the surfaces of the inflatable portions, or other areas, of the water attractions (e.g., to increase or decrease friction coefficients of certain surfaces with respect to others). One or more inflatable portions may be positioned at any desired location along the water attraction, for example, to provide a less rigid surface for more comfortably supporting riding thereon and/or to absorb an impact of the rider or a ride vehicle. In one example, the inflatable structure may be completely above ground, completely below ground, or partially above and partially below ground. In some embodiments, a water reservoir of the water attraction may be made of the inflatable material.
A water attraction using an inflatable portion or portions may be modular in nature such that it may be more easily manufactured, transportable, and/or constructed at a given location. For example, a water attraction using an inflatable portion or portions may be designed to be portable such that it is intended to be used at a given geographic location for a short period and then deflated and/or deconstructed and shipped to a new location. A rifting pallet (e.g., configured to interface with a forklift or other equipment designed to couple therewith for transportation) may be integral, built in, or otherwise attached with a surface of a water attraction (e.g., on an underside, to the draining surface, sliding surface, or any other component) in order to more easily move the water attraction between geographic locations. Certain embodiments may utilize different colors, textures, patterns, etc. upon different areas or surfaces of the water attraction, for example, to help riders distinguish between queuing / non-riding areas and the riding areas of the attraction. Certain embodiments, including any of those previously discussed, may utilize a sheet flow of water or a deep flow of water to generate a standing wave ride.
