Deep Water Stationary Wave System and Method

This application is a continuation of U.S. patent application Ser. No. 18/055,827 filed Nov. 15, 2022, entitled “DEEP WATER STATIONARY WAVE SYSTEM AND METHOD”, which claims priority to U.S. Provisional Patent Application No. 63/264,096, dated Nov. 15, 2021, “WAVE SYSTEM AND METHOD”, the entire content of each of which is hereby incorporated by reference.

Water attractions have brought fun to different people from different geographic locations for many generations. The water attraction permits different geographic areas to have access to simulated experiences from other geographic areas. For example, a wave pool may approximate an experience at a beach.

Different water attractions may be used to approximate natural environments to permit users to experience sports and activities from these other environments. For example, sheet wave rides simulate a surfing or boogie boarding experience that permits a rider, with their body or a thin board, to ride upon a sheet flow of water that is contoured by an underlying ride area floor. The sheet wave ride does not provide a true surfing experience, as the sheet flow does not permit wave breaking or the use of an actual surfboard.

Deep wave surfing systems are provided that attempt to create a more accurate approximation of the surfing experience in the natural environment. Examples of wave systems may be found in, for example, U.S. Pat. Nos. 6,629,803; 6,738,992; 6,928,670; 6,932,541; 7,326,001; 7,568,859; 7,658,571; 7,717,645; 7,722,291; 7,815,396; 8,303,213; 8,496,403; 8,516,624; 9,144,727; 9,777,494; 10,119,285; United States Patent Publication Numbers 20150089731; 20160053504; 20180266129; and International Patent Application Publication Numbers WO2018083265; WO2018149969; WO2018188741; WO2019018573, all of which are incorporated by reference in their entirety herein.

A wave system is disclosed herein. The wave system may include an obstacle in which water is pushed over to create a wave contoured surface for riding or maneuvering by a user.

The exemplary wave system may include an adjustable obstacle for changing the wave contoured surface of the water flowing over the obstacle. Exemplary embodiments may include a controller for adjusting the obstacle for desired configurations. In an exemplary embodiment, the obstacle may be static in position, and/or may be absent from the wave system entirely.

The exemplary wave system may include a declined surface extending from the water outlet toward the obstacle. The declined surface may be bounded by interior side walls. The interior side walls may be tapered, narrowing from a wider end near the water outlet to a narrower end adjacent the object. Exemplary embodiments may include different combinations of tapered and/or non-tapered interior side walls.

The exemplary wave system may include a water cycle in which water leaves the water outlet, over the obstacle, through a water drainage system, through a reservoir under the water ride area, and back to the water outlet. In an exemplary embodiment, the wave system may include a pump system in the reservoir under the ride area. The pump system may be position at or rearward of the obstacle and toward a rear of the wave system. The pump system may include a moveable mechanism for translating the pumps from a first position to a second position. The pump system moveable mechanism may be used to access the pumps for installation, maintenance, and/or replacement. Exemplary embodiments of the pump system may include pump inlets that are positioned toward a lower portion of the reservoir for drawing water into the pump from a bottom of the reservoir away from the water surface.

The exemplary wave system may include a water conditioner. Exemplary embodiments of the wave conditioner may be create by sheets having apertures therein. The sheets may be positioned in direct contact or may be positioned with gaps between adjacent sheets.

The exemplary wave system may include a water level controller in which a water level of the tail water or water level at the end of the wave near the water drainage area may be adjusted. The water level controller may be used to adjust the water level in the reservoir and in the area of the generated wave in order to adjust or effect the shape and/or size of the generated wave.

The following detailed description illustrates by way of example, not by way of limitation, the principles of the invention. This description will clearly enable one skilled in the art to make and use the invention, and describes several embodiments, adaptations, variations, alternatives and uses of the invention, including what is presently believed to be the best mode of carrying out the invention. It should be understood that the drawings are diagrammatic and schematic representations of exemplary embodiments of the invention, and are not limiting of the present invention nor are they necessarily drawn to scale.

Exemplary embodiments described herein include a wave generation system and methods for generating a rideable wave.

Although embodiments of the invention may be described and illustrated herein in terms of a rideable wave, it should be understood that embodiments of this invention are not limited to any specific or required wave size and/or shape. As disclosed herein, exemplary embodiments may create different water surfaces, configurations, and experiences, all of which are within the scope of the instant disclosure. In addition, different features and combinations of structures, configurations, shapes, and components are provided as exemplary only. No feature, objective, or result is necessary to the invention, and therefore, no corresponding structure, component, or configuration is required or necessary to the invention. Instead, any combination of features, components, and configurations may be used in any combination and remain within the scope of the instant description. For example, any wave system described herein may be used with any described obstacle, wave conditioner, water level controller, pumps, declined surface, reservoir, water chambers, or without any one or more of these features and remain within the scope of the instant disclosure.

illustrates an exemplary wave system according to embodiments described herein. The exemplary wave systemmay include a water outletfor introducing water onto a rideable area of the ride. The wave systemmay include an obstacle. Water introduced onto the ride from the water outletmay encounter the obstacleto generate a contoured wave surface with the water. The contoured wave surface of the water (not shown) may be used as a rideable wave. The wave systemmay include a water drainage systemto remove the water from the ride area and/or permit rider exit. The wave systemmay also include a containment structurefor holding and containing the water and wave system components. As used herein, the term “ride area” is intended to encompass the upper portion of the ride attraction upon which water flows during operation. With reference to, the ride area would encompass the area from declined surfaceto the end of the water drainage system.

As seen in, the obstacleis positioned between the front of the wave systemwhere water is introduced at the water outletand the back of the wave system where water is removed at the water drainage system. As illustrated, the obstaclemay be connected or positioned relative to or integrated into the ride structure such that it forms a generally convex shape above a horizontal plane of a floor surface of the ride area. The obstacletherefore defines a local maximum elevated surface relative to portions of the floor surface adjacent to the obstacle. The obstacle is configured to cause the water flowing thereover to back up creating a desired contoured wave surface for riding by a user.

As seen inand, the obstaclemay extend transversely across at least a portion of the ride structure from one lateral sideto an opposing lateral sideof the rideable area. The rideable areamay be over the top of the ride structure over the obstacle, toward the water outletfrom the obstacle, and in the area adjacent the obstacle in which the contoured wave surface is created with the water flows thereover. The obstaclemay have a constant or variable cross sectional profile as the obstacle is traversed laterally across the rideable area. For example, as illustrated, the obstacledefines an elevated surface that is the same across the ride area. Other configurations of the obstacle may also be used. For example, the obstacle may be separate segments that may be positioned adjacent one another across the rideable area. In an exemplary embodiment, more than one obstacle may be used, which may be positioned at different locations laterally (side to side) and/or longitudinally (front to back) on the rideable area. As another example, the obstacle may include a variable cross sectional profile as the obstacle is traverse laterally across the rideable area. For example, the obstacle may include a curvature is a horizontal plane, such that one portion of the obstacle may be positioned in front of or behind another portion of the obstacle relative to the water outlet. As described herein in more detail, exemplary embodiments may include the dynamic changing of the obstacleshape, and/or obstacle location on the ride area.

As more easily observed in, the obstacle can include one or more shaped surfaces. As illustrated, the obstacle may include a front surface, a transition surface, a rear surface, and any combination thereof. The front surfacemay be an upwardly sloped surface above the ride floor, such as at transition surfaceand/or. As illustrated, each of the front surface, transition surface, and rear surfaceare planar. However, each surface may also be concave curved, convex curved, compound curved, or combinations thereof. As illustrated, each of the front surface, transition surface, and rear surfaceare stepwise coupled creating a discontinuous surface encountered by the water as it flows over the obstacle. Exemplary embodiments may include curvatures on portions of and/or between the respective surface(s), transition segments, integration between segments, or contouring surfaces and/or layers across one or more segments to reduce the discontinuity and/or create a continuous surface from the front of the obstacle to the top of the obstacle or to the back of the obstacle.

In an exemplary embodiment, the wave systemmay include a declined surface. The declined surfacemay be positioned adjacent the water outlet. Exemplary embodiments may have the water outletat a higher elevation and the declined surfaceis configured to move the water to a lower elevation before encountering the obstacle. The declined surfacemay be configured to increase the velocity of the water encountering the obstacle. The declined surfacemay be used to create a trough between the declined surfaceand the obstacleto influence the shape of the contoured wave surface created by the water. The wave systemmay also include a transition surface between the declined surfaceand the obstacle. The transition surfacemay define a minimum elevation of a ride area floor. The transition surfacemay be planar and horizontally level. The transition surfacemay be contoured to transition the flow of water from the declined surface toward the obstacle.

As best illustrated by the top elevation view of the wave system and declined surfaceof, the declined surface may have opposing interior walls. The interior wallsmay contain the flowing water from the water outlet and down the declined surface. As illustrated, the opposing interior walls may be inwardly tapered from a first end toward the water outlettoward a second end toward the obstacle. A cross-wise, lateral distance between opposing interior wallsdefines an interior diameterof the declined surface. As illustrated, the diameterof the declines surfaceis greater proximate the water outletand lesser proximate the obstacle. The taper may extend from adjacent the water outletnear the obstacle, to a beginning edge of the obstacle, near the maximum elevated portion of the obstacle, or after the obstacle. In an exemplary embodiment, the tapering of the opposing interior wallsmay be used to reduce sidewall effects on the water as the water flows down the declined surface. For example, the frictional effects of the sidewall may cause turbulence and white-water to occur near the interior walls of the ride. The tapering may be used to increase the speed of the water and minimize the sidewall effects. The tapered sidewalls may therefore be used to reduce the appearance of turbulence in the flowing water to create a smoother, glassier water surface. The interior wallsmay be tapered along an entire length of the declined surface or any portion thereof. For example, the interior wallsmay include a parallel or non-tapered portion adjacent the water outlet, but a tapered portion toward the obstacle end of the declined surface. In an exemplary embodiment, the walls may interior wallsmay also be inwardly or outwardly tapered as the interior wall is traversed upward in elevation above the ride area floor. For example, the interior wallsmay be angled inwardly or outwardly from the vertical plane.

Referring back to, the wave system may include a water drainage system. As illustrated, the water drainage systemmay be positioned on an opposite side of the obstaclethan the water outlet. The water drainage systemmay remove the water from the ride area floor or from the ride area. In an exemplary embodiment, the water drainage systemmay recycle the water back to the water outlet. For example, the water drainagemay include a portion of the ride area floor having apertures or passages there through for permitting the passage of water from the ride area to an area below the ride area floor. Other drainage systems may be used, such as drainage surface on the lateral sides and/or the tops of the lateral sides of the sidewalls of the ride structure. Any combination of drainage features may be used in any combination. As illustrated, the wave systemmay include a transition surfacebetween the obstacleand the drainage system.

As illustrated, the water drainage systemmay include an inclined surface. The inclined surface may be configured such that a user may exit the ride area by walking on the inclined surface out of the water. The inclined surface may therefore be textured, contoured, shaped, or through the apertures create an increased frictional surface for easier standing and walking by the user. The drainage systemmay also include an extended rear section. This area may be used to slow a rider, permit spectator viewing, permit operator positioning and/or availability for assistance of users, and combinations thereof. As the water drainage system may be impacted by the user after riding the contoured wave surface of the water generated by the obstacle, the water drainage system may be padded or have other impact resistant features. In an exemplary embodiment, the water drainage system may have a flexible covering and/or surface.

As illustrated in, the wave systemmay include a containment structure. The containment structuremay contain the water within system. The containment structure may provide structural support for one or more components of the wave system. In an exemplary embodiment, the containment structure is sufficiently strong to retain and the amounts of water for the ride operation. In an exemplary embodiment, the containment structureis configured to retain water below the ride area. The containment structure may therefore define a reservoir for passing water received from the drainage systemunder the ride area back to the water outlet. As described more fully herein, the reservoir below the ride area may include one or more pumps for moving water as described herein. In an exemplary embodiment, the containment structures is concrete. In an exemplary embodiment portions or all of the ride area floor and/or containment structure may be concrete. For example, the declined surfacemay include a concrete under layer to support the flowing water from the water outlet. The containment structure, and/or portions of the wave system may include one or more access panels and/or doors to allow access to components and/or locations within the wave system structure.

illustrate cross sectional views of an exemplary wave system according to embodiments described herein. As illustrated by the dashed lines of, the water may be circulated from the water outlet, down the declined surfaceto encounter the obstacleand create the contoured wave surface with the water, to drain through the drainage systemto be moved through the reservoirby nozzles.

Exemplary embodiments may also include water filters. Water filters may be used to reduce debris in the system that may clog the nozzles and/or create obstacles for riders while they are within the ride area. In an exemplary embodiment, the water drainage systemmay provide a first filter. As described herein, the water drainage systemmay include a porous to permit water to pass there through. The water drainage systemmay be configured to filter out materials larger than a desired size. For example, the water drainage systemmay be used to keep a person, body parts, clothing, shoes, boards, riding vehicles, bracelets, watches, phones, cameras, wallets, and other objects that may be lost by a user while riding the wave system. One or more filters may also be positioned on an inlet and/or outlet side of the nozzle. One or more filters may also be positioned before or proximate to the water outlet. The filters may be removable and/or replaceable for maintenance and/or easy cleaning. The filters at the nozzles may be supported by the nozzles for access according to embodiments described herein.

Exemplary embodiments may also include one or more water conditioner,. The water conditioner,may be positioned adjacent a water outlet. The water conditioner may be configured to reduce turbulence in the water flow. Exemplary water conditioner may include a system of apertures for passing the water. For example, a conditioner may include a planar structure including a plurality of apertures therein. The conditioner may include a mesh, expanded metal, net, or other configuration. Exemplary embodiments of a conditioner is described in more detail herein in reference to.

As described herein, the water conditioners and/or position of the pumps may be used to reduce turbidity of the water coming from the water outlet. For example, as the water travels from the pumps, the water turbidity may be reduced. Therefore, the further the pumps are from the water outlet, the less turbidity there may be in the water outlet. However, the further the pumps are from the water outlet, the more power is required to push the water through the system. The conditioners may also be used to reduce turbidity in the water. However, the more conditioners that are present or the more interference to the cross sectional area of the water passage, the more power is required to push the water through the conditioners.

As shown and described herein, the wave systemmay include one or more surfaces for supporting, containing, and/or moving water. The surfaces illustrated herein are generally planar surfaces creating discontinuity between one surface area to an adjacent surface area. The invention is not so limited. Instead, surfaces may include fillets or other tapered, curved, or transitional area to reduce the discontinuity between surfaces, and/or create a continuous transition from one surface to an adjacent surface. The transition may be accomplished through contouring of either or both of the adjacent surfaces. The transition between surfaces may be through one or more layers or coatings between adjacent surfaces. For example, as seen in, a filletmay be used at a surface transition between the reservoir and the water outlet. The filletmay be a curved surface to create a continuous transition between an upwardly extending wall from the reservoir to the downwardly inclined declining surface to the ride area.

The surfaces shown and described herein may include additional features, such as surface coatings, drainage features, additional layers, and combinations thereof. The additional features may be to reduce the effects of impact by a user or reduce injury during the ride experience through contact with the surface. The additional feature may include foam or other padding. The additional features may be to reduce the impacts of the environment on the wave system or system components. For example, additional features may include UV resistant, water resistant, chlorine resistant, etc. protections and/or coatings. Additional features may include sealants to reduce water penetration into parts of the system. Additional features may include frictional engagement or frictional reducing structures, coatings, and/or layers. Exemplary portions of the system may benefit from reduced friction, such as at or along the declined surface, while portions of the system may benefit from increased friction, such as at or along the drainage system. Any combination of additional features may be used with any features described herein.

illustrate an exemplary view of an exemplary embodiment of an adjustable obstacle described in a related application. In an exemplary embodiment, the obstacleis deformable such that the obstacle may present a different cross sectional front profile to oncoming water. The size of the obstacle front profile may be used to vary or change the contoured wave surface created with the water flowing over the obstacle.

illustrates an exemplary embodiment of an obstacleaccording to embodiments described herein. As illustrated, the obstacleincludes an actuator for adjusting a profile, shape, orientation, height, angle of attack for inbound water, or a combination thereof. As illustrated, the actuator may be a bladderthat is filled with a substanceto inflate or change the contour, profile, shape, orientation, height, angle of attack, or any combination thereof. The bladdermay be configured with one or more valves for permitting the substance to enter the bladder as well as vacate the bladder. The substance may be air, liquid, or solid.

As illustrated in, the obstacle may include a cover layer. The cover layer may be used to provide a smoother transition for the passage of water over the obstacle than the actuator and/or other obstacle components without the layer would provide. The layer may be used to provide surface characteristics, such as a smoother, reduced frictional surface for passage of water there over. In an exemplary embodiment, the cover layer may be configured such that a length of a surface encountered by flowing water from the front of the layer or obstacle to the back of the layer or obstacle can be changed as the obstacle is changed according to embodiments described herein. For example, the cover layer may extend into and out of a surface of the wave system as the bladder is deflated and inflated, respectively. The cover layer may be elastic or stretchable thereby providing the necessary deformation for expansion by the bladder. The cover layer may be overlapping or telescoping, pleated, or otherwise deformable to permit the desired actuation to change the obstacle as described herein. The obstacle may include one or more additional surfaces for providing increased rigidity and/or a desired surface to encounter the water. The surface may be planar, curved, complex curved, or a combination thereof.

Exemplary embodiments may include a controller coupled to the actuatorfor controlling a shape of the obstacle. Changing a shape of the obstacle may include any combination of a change in a front profile of the obstacle, a height of the obstacle, a slope of one or more surfaces of the obstacle, a cross sectional profile of the obstacle, an orientation of the obstacle and/or any component part of the obstacle, etc. The controller may be configured to dynamically control a position and/or shape of the obstacle. The controller may permit a user to select a position and/or shape of the obstacle. The controller may permit a user to select a skill level, such as beginner, intermediate, and experienced. The controller may thereafter position the obstacle at a corresponding shape associated with the selection of the skill level. The controller may also include a programmer. The programmer may include a schedule that permits a user to select an obstacle shape at desired times, intervals, etc. The programmer may communicated with the actuator to adjust or change the obstacle shape according to the desired or entered schedule. The controller may also be configured to adjust the shape of the obstacle based on the operational time of the wave system. For example, during start up or shut down, the shape, such as the height, of the obstacle may be minimized. The reduction in the obstacle may permit the water to flow over the obstacle more easily and reduce the start-up water agitation. Once the water has run for a predetermined amount of time, the obstacle may be increased in size so that the contoured water surface may be created.

In exemplary embodiments, the wave system may also include a controller for adjusting an amount of water through the pumps. The controller of the pump may adjust a flow rate of the pump. The combination of either or both of the adjustments to the obstacle and/or the pump flow rates may be used to change the contoured wave surface of the water. The adjustment to the contoured wave surface of the water may be used to provide different ride experiences. The adjustment to the pump flow rate and/or obstacle shape may be used to create a contoured wave surface to correspond with an experience level of the user.

Referring back to, exemplary embodiments of the wave systemincludes an obstaclefor creating a contoured wave surface with the water for riding or performing maneuvers by a user. As described herein the obstaclemay be positioned around a central area of the ride structure. In an exemplary embodiment, the nozzlepositioned below the ride area may be proximate to, in line with, or rearward (on a side opposing the water entry and toward the water drainage system) of the obstacle. Exemplary embodiments may include a removable water drainage portion. The wave system may therefore permit access to the reservoirthrough all or a portion of the water drainage surface. By positioning the water pumps rearward of the obstacle, the pumps may be closer to, proximate to, or under a portion of the water drainage surface. The nozzles may therefore be easier to access for replacement, installation, and/or maintenance. As described herein, exemplary portions of the containment structure, and/or surfaces,,may be concrete. Therefore, access under or through these surfaces may be difficult. Access through the removable pump system may therefore improve ease of access without weakening or compromising the structural infrastructure and/or complicating the infrastructure. However, access panels may also be provided in the wave system. For example, access panels may be provided through the ride area floor and/or through exterior wall sin order to access areas that may include components parts, such as filters.

illustrates a perspective view of the wave systemwith the water drainage system surface portion removed to permit viewing of the nozzles positioned thereunder.illustrates a perspective view of an exemplary nozzle according to embodiments described herein for use in an exemplary wave system. As illustrated, a portion of the nozzles may extend rearward or be positioned proximate to the end of the concrete portion of the containment structure defining a portion of the ride area floor (surfacesand/or).

As illustrated, in an exemplary embodiment, the pump systemmay include a water inletand water outlet. The water inletmay be configured to draw water from a lower portion of the reservoir. As illustrated, the water inletincludes a front surface. The front surfacemay be configured to attach or couple to the infrastructure of the wave system. The pump systemmay be configured to draw water from the reservoir near the top, middle, bottom, or a combination thereof of the reservoir. In an exemplary embodiment, the system may be configured to draw toward the bottom of the reservoir. Water from the top surface of the water level within the reservoir may be aerated and/or may draw in air from above the surface of the water level. In some cases, if the water is pulling from the water surface into the water inletof the pump, the system may pull in air from the water surface. This may occur if a vortex from the water surface is created at the water inlet into the pump. When this air is pulled through the pump and ejected with the water onto the ride area floor, it may cause cavitation. The pump may include components to reduce the cavitation of the system by limiting the air being pulled from a surface of the water. For example, the pump may include a lip (not shown) that extends over a top of the water inlet. The lip may reduce the water directly pulled from the surface and reduce a corresponding amount of air into the pump system. Other features may also be used to direct the water from lower in the water column. For example, tubes or other passages may be used to direct water from a desired location within the water column. These components and features may be selected based on the water level and the clearance of the system above the ground of the reservoir. The wave system may also include an intermediate layer between the water drainage system and the reservoir that may reduce the aeration of the water before it enters the pumps. Such layers may include surface structures at the top of the reservoir, or other intermediate structure to reduce the impact of the water returning from the ride area floor to the reservoir to reduce the churning and/or incorporation of air into the water within the water column of the reservoir before the water enters the pump(s).

As illustrated, the pumpsmay be moveable relative to the containment structure. In an exemplary embodiment, the relative movement may be achieved or facilitated through the use of a movement system. In an exemplary embodiment, the relative movement may be achieved through the use of rollersand/or tracks. As illustrated, the pumpsmay include a plurality of rollersto support the pumps. The rollersmay be positioned on corresponding tracksto control the relative position and movement of the rollers. Although rollers on tracks are illustrated as an exemplary movement system, other system may be used, such as telescoping rails, sliders, or other systems for linear translation of component parts. Although linear translation is shown and describe, and specifically a single axis translation along rails, the invention is not so limited. Other systems may be used. For example, a two-axis linear translation system like a gantry system may be used. Other configurations may permit translation in a first direction then followed by translation in a second direction. This configuration may permit the pumps to act like an access panel, pulling them out and then over to permit an opening under the ride area floor. Other configurations and movement platforms are also considered herein.

Exemplary embodiments of the wave systemaccording to embodiments described herein may include a pump system having a first position and a second position.illustrate a cross sectional view of the wave system in which the pumps are in a first and second position.illustrate a top elevation view of the wave system with the water drainage portion removed to permit viewing of the pumps in the first and second position, as described herein. In an exemplary embodiment, the first position of the pump (as seen in) may be an in use position. The pumpmay be positioned in a forward position toward the water outlet. In an exemplary embodiment, the forward position may be with a portion or all of the pump positioned under or proximate a portion of the containment structure or ride structure, such as surface, surface, obstacle, or combinations thereof. The pumps may be secured into the first position such as by lock on movement system, bolting or other attachment of the pump structure to the infrastructure, such as portions of the containment structure, or combinations thereof. The second position of the pump (as seen in) may be in an exposed configuration. The second position may be rearward (away from the water outlet) than the first position. The second position may exposed a portion or all of the pump structure. The second position may therefore improve efficiencies for repair, replacement, installation, and combinations thereof.

Referring back to, or, exemplary embodiments of a wave system described herein may include a water conditioner,,.illustrates exemplary components of a water conditioner according to embodiments described herein. Exemplary embodiments of a water conditioner include a plurality of sheets having apertures there through. Adjacent sheets of the plurality of sheets may be separated by a gap. The front sheet is illustrated for sake of clarity as solid lines, while sheets removed from the front surface are illustrated in dashed lines. The plurality of sheets may therefore define parallel planes that have a separation gap there between. Exemplary embodiments may have the same or different separation gaps between different adjacent sheets. In an exemplary embodiment, different sets of sheets may be coupled together. For example, a first set of sheetsmay be coupled together, a second set of sheetsmay be coupled together and a third set of sheetsmay be coupled together. Different sets of sheets may thereafter be stacked to create a water conditioner. As illustrate, the aperture size, configuration, position, shape, orientation, and combinations thereof may be different between two or more sheets or set of sheets. In an exemplary embodiment, different aperture sizes, orientations, shapes, or other configuration is used between two or more sheets. With the variability between sheets, the apertures and structure defining the apertures will overlap between the different sheets. The overlap between the different sheets may therefore create a small mesh size or overall aperture size so that the water has a higher probability of contacting a sheet structure as it traverses from one end of the conditioner to another. As illustrated, the sheets may be crated from expanded metal. Metals sheets may have slits cut therein. The metal is then expanded to create the different aperture size and shapes.illustrates and exemplary embodiment in which three sets of panels are used having different configurations, whileillustratessets of panels are used, in which each panel includes a plurality of sheets having apertures there in.

illustrates an exemplary wave system according to embodiments described herein. The exemplary wave systemmay include a water outletfor introducing water onto a rideable area of the ride. The wave systemmay include an obstacle. Water introduced onto the ride from the water outletmay encounter the obstacleto generate a contoured wave surface with the water. The contoured wave surface of the water (not shown) may be used as a rideable wave. The wave systemmay include a water drainage systemto remove the water from the ride area and/or permit rider exit. The wave systemmay also include a containment structurefor holding and containing the water and wave system components.

In an exemplary embodiment, the wave systemmay include a declined surface. The declined surfacemay be positioned adjacent the water outlet. Exemplary embodiments may have the water outletat a higher elevation and the declined surfaceis configured to move the water to a lower elevation before encountering the obstacle. The declined surfacemay be configured to increase the velocity of the water encountering the obstacle. The declined surfacemay be used to create a trough between the declined surfaceand the obstacleto influence the shape of the contoured wave surface created by the water. The wave systemmay also include a transition surface between the declined surfaceand the obstacle. The transition surfacemay define a minimum elevation of a ride area floor. The transition surfacemay be planar and horizontally level. The transition surfacemay be contoured to transition the flow of water from the declined surface toward the obstacle.

As seen in, the obstacleis positioned between the front of the wave systemwhere water is introduced at the water outletand the back of the wave system where water is removed at the water drainage system. As illustrated, the obstaclemay be connected or positioned relative to or integrated into the ride structure such that it forms a generally upwardly angled projection above a horizontal plane of a floor surface of the ride area. The obstacletherefore defines a local maximum elevated surface relative to portions of the floor surface adjacent to the obstacle. The obstacle is configured to cause the water flowing there over to back up creating a desired contoured wave surface for riding by a user.

The obstaclemay extend transversely across at least a portion of the ride structure from one lateral side to an opposing lateral side of the ride area. With reference to the embodiment in, the ride area would encompass the area from and including declined surfaceto the end of the water drainage system. The obstaclemay have a constant or variable cross sectional profile across the rideable area. For example, as illustrated, the obstacledefines an elevated surface that is the same across the ride area. Other configurations of the obstacle may also be used.

As more easily observed in, the obstaclecan include one or more generally planar or shaped surfaces. As illustrated, the obstaclemay include a front surface and a back surface, and any combination thereof. The front surface may be an upwardly sloped surface above the ride floor, such as at transition surface. Exemplary embodiments may include curvatures on portions of and/or between the respective surface(s), transition segments, integration between segments, or contouring surfaces and/or layers across one or more segments to reduce the discontinuity and/or create a continuous surface from the front of the obstacle to the top of the obstacle or to the back of the obstacle.

Referring back to, the wave system may include a water drainage system. As illustrated, the water drainage systemmay be positioned on an opposite side of the obstaclethan the water outlet. The water drainage systemmay remove the water from the ride area. In an exemplary embodiment, the water drainage systemmay recycle the water back to the water reservoir and subsequently back to the water outlet. For example, the water drainagemay include a portion of the ride area floor having apertures or passages there through for permitting the passage of water from the ride area floor to the reservoir. Other drainage systems may be used, such as drainage surface on the lateral sides and/or the tops of the lateral sides of the sidewalls of the ride structure. Any combination of drainage features may be used in any combination. As illustrated, the surface after the obstaclemay comprise a drainage area. The surface may therefore include apertures that permit the flow of fluid through but may be small enough to permit a user to stand, walk, or otherwise be kept from passing there through. As illustrated, the drainage surface is shown in cross hatching.

As illustrated, the water drainage systemmay include an inclined surface, a lower surface, and an upper surface. The inclined surface may be configured such that a user may exit the ride area by walking on the inclined surface out of the water. The inclined surface may therefore be textured, contoured, shaped, or otherwise create an increased frictional surface for easier standing and walking by the user. The drainage systemmay also include an extended rear section. This area may be used to slow a rider, permit spectator viewing, permit operator positioning and/or availability for assistance of users, and combinations thereof. As the water drainage system may be impacted by the user after riding the contoured wave surface of the water generated by the obstacle, the water drainage system may be padded or have other impact resistant features. In an exemplary embodiment, the water drainage system may have a flexible covering and/or surface.

As illustrated in, the wave systemmay include a containment structure. The containment structuremay contain the water within the system. The containment structuremay provide structural support for one or more components of the wave system. In an exemplary embodiment, the containment structure is sufficiently strong to retain and the amounts of water for the ride operation. In an exemplary embodiment, the containment structureis configured to retain water within and below the ride area. The containment structure may therefore define a reservoir for passing water received from the drainage systemunder the ride area back to the water outlet. As described more fully herein, the reservoir below the ride area may include one or more pumps for moving water as described herein. In an exemplary embodiment, the containment structureis concrete. In an exemplary embodiment all or a portion of the ride area floor may be fiberglass. Alternatively, portions of the ride area floor may be concrete covered with a cushioned material such as neoprene or foam. The containment structure, and/or portions of the wave system may include one or more access panels and/or doors to allow access to components and/or locations within the wave system structure.

The water may be circulated from the water outlet, down the declined surfaceto encounter the obstacleand create the contoured wave surface with the water, to drain through the drainage systemto be moved through the reservoir by pumps, as shown in. In exemplary embodiments, the wave system may also include a controller for adjusting an amount of water through the pumps. The controller of the pump may adjust a flow rate of the pump. The combination of either or both of the adjustments to the obstacle and/or the pump flow rates may be used to change the contoured wave surface of the water. The adjustment to the contoured wave surface of the water may be used to provide different ride experiences. The adjustment to the pump flow rate and/or obstacle shape may be used to create a contoured wave surface to correspond with an experience level of the user.

Exemplary embodiments described herein may include a mechanism for controlling the height of the water in the reservoir to further affect the shape of a contoured wave.illustrates an exemplary cross sectional view of an exemplary wave system according to embodiments described herein. The reservoirmay be segregated to include a tailwater tank(or first portion) of the reservoir below the ride area floor, and a charge tank(or second portion) that is preferably at the rear portion of the ride behind any generated wave, near the water recovery area. Alternatively, the charge tank could be located at a different location in the reservoir. For example, the charge tank could be pushed off to the side under the ride area floor, if needed. The segregation of the reservoir may be used to control the height of the tailwater of the wave generation system. The height of the tailwater may be used to control a height and/or shape of a wave. As shown, the reservoir may be defined or enclosed in a container having an outer wall and a floor. A vertical wallmay separate the first portionof the reservoir from the second portionof the reservoir. The vertical wallmay be positioned in a rear portion of the wave generating device, such as in the water recovery area.

As illustrated in, the vertical separation wallbetween the first portionof the reservoir and the second portionof the reservoir may control an amount of water between the two portions. As illustrated, the separation wall comprises a pumpfor moving water from the second portionof the reservoir, away from the ride area floor, to the first portionof the reservoir that includes an area below the ride area floor. The separation wall may also or alternatively comprise a variable surfacethat allows at least a portion of the top of the wallto change height. Water from the first reservoir may therefore flow over the top of the variable surface. In the embodiment depicted inthe variable surfacecomprises only a relatively short length of the top of the wall. Alternatively, the variable surface could be wider or narrower, comprising the entire length of the wall, or only a portion of the width, depending on how fast the water level is desired to change. A wider variable surfacewould allow for faster changes in water level, while a narrower variable surfacewould allow for slower changes in water level. In one embodiment, a plurality of variable surfacesmight be placed along the same vertical wall, in which case each of the plurality of variable surfaceswould preferably be adjusted by the same amount.
