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 surface. 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. U.S. Pat. Nos. 8,434,966, 9,103,133, 9,279,263, 10,145,135, 10,280,640, and 10,526,806 disclose deep wave surfing simulators, each of which is incorporated by reference in their entirety herein.
A pool wave generator is disclosed having a pool area and a plurality of chambers for generating a wave in the pool area. The plurality of chambers may be used to retain or release water into the pool to create a desired wave.
The plurality of chambers may be separated from an edge of the pool to create a gap there between. A passage may be positioned below the gap to fluidly couple the chamber to the pool. The passage may be used to reduce turbidity or limit eddy currents in the fluid as the water is moved between the chamber and the pool. The gap may permit spectators or the storage of controllers, blowers, pumps, or other components and/or equipment of the pool wave generator. In an exemplary embodiment, the gap may include a floor for supporting a spectator. The gap may also include an edge that corresponds to an extension of an edge of the pool. The edge of the gap may include a transparent wall to permit observation of the pool activities from a location within the gap.
The pool wave generator may also include a pool floor and/or pool edge for influencing a wave profile or wave characteristics and/or for creating different wave zones. The pool floor may include different combinations of tapered sections and/or horizontal sections, or other contours for creating different breaking waves of different characteristics.
The pool wave generator may also include outwardly flared walls extending away from the plurality of chambers. The wall positions may be used to reduce and/or control eddy currents created from the water's interaction with the wall and/or floor.
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 pool configured to create waves. The pool may include one or more chambers at one end that are configured to receive and release water into the pool for generating the waves. Exemplary chambers are provided to reduce turbulence and generate better waves for riding. The pool may be configured to generate zones that define or generate waves of different profiles and/or for riding by riders of different experience levels.
Although embodiments of the invention may be described and illustrated herein in terms of a pool wave generator having unique and novel features, it should be understood that embodiments of this invention do not require or necessitate the inclusion of each of the features. The instant disclosure does not require any specific component, configuration, or feature, and any combination of features may be incorporated or combined and remain within the full description of the invention. For example, the inclusion of the elongated chamber between the chamber and the pool to reduce eddy currents may be used in any conventional features of a pool wave generator. Similarly, the inclusion of the spectator area, and/or the bottom contour to generate different wave zones may similarly be used alone or in conjunction with other features described herein.
In an exemplary embodiment, the pool area 12 may be a recessed pool configured to hold water. The terminal end 18 may be a wall for retaining the water. The wall may be vertical or may be sloped. In an exemplary embodiment, the terminal end is created by a sloped bottom of the pool to approximate or similar a beach area. As the water is pushed across the pool area 12 by the release of water from the chambers 14, the water may travel toward the terminal end and travel across and up the sloped bottom until the water stops and eventually comes back to the pool area along the sloped bottom under the influence of gravity.
As represented by the arrows adjacent the chambers 14, the chambers 14 may release water into the pool area 14 sequentially. The chambers may be linearly aligned along one side of the pool 12. The chambers may also include different directions, configurations, and orientations. The release of water from the chambers may be used to control wave attributes, such as a wave height, direction, shape, etc. As illustrated in
Angling the opposing lateral sides may also be used to control the currents of the pool according to embodiments described herein.
Exemplary embodiments described herein may include a pool having a first linear edge in which a plurality of chambers are configured to fluidly couple and dispense water into the pool along the first linear edge. One or more chambers may be configured along an entirety of the first linear edge. The pool may include two opposing lateral sides extending from terminal ends of the first linear edge. The opposing lateral sides may extend forward of the first linear edge at an angle. The angle of each lateral side may be the same or different, depending on the pool configuration. The opposing lateral sides may extend outward and forward from the first linear edge at an oblique angle. Exemplary embodiments of the angled opposing lateral sides may assist in current mitigation. Exemplary embodiments of the angled opposing lateral sides may also focus a wave's energy such that a wave may be reformed for different experience levels. Exemplary embodiments include an oblique angle measured from the front of the linear position of chambers outward and around through the pool area and to the linear side wall. The oblique angle is preferable greater than 90 degrees and less than 180 degrees. The oblique angle may also be greater than 110 degrees, greater than 120 degrees greater than or approximately 135 degrees, greater than or approximately 150 degrees, or greater than or approximately 160 degrees. The oblique angle may also or in addition be less than 180 degrees, less than 170 degrees, less than or equal to 160 degrees, less than or equal to 150 degrees, or less than or equal to 135 degrees.

In an exemplary embodiment, the system is configured to cycle through the process of releasing water from the chamber and permitting the resurgence of water into the chamber. The system may also include a delay after any number of cycles to permit the water in the pool to settle and reduce turbulence that could affect wave generation.
In the exemplary embodiment provided herein, two valves are illustrated—a first valve 22 for water control and a second valve 24 for gas control. Any combination of valves may be used and are within the scope of the instant disclosure. For example, multiple gas valves may be used to vent the chamber, inject pressurized gas, etc., and multiple fluid valves may be used to emit or retain the water within the chamber. The order and/or cycle of the valves as described herein is exemplary only. Any number of different ways may be used to release the wave using valves, gates, or other methods. The valves may be opened, closed, in different ways. For example, the system may use a purge system to remove gas from the chamber before resurgence of water to elevate the water level returning to the chamber. For example, the system may not use a pressurized gas system for expelling the water into the pool. For example, single direction valves may be used such that valves do not necessitate individual actuation to open and close each valve. The valves of each chamber may be controlled individually or as a sequence within a larger operation of the entire pool system.
In an exemplary embodiment, multiple wave zones 36, 37, 38 may be created. The creation of multiple wave zones may be generated from a single wave generation cycle of the chambers. For example, the chambers may release in sequence to form a first wave. That first wave may change profile, height, direction, etc. as the wave propagates across the pool floor. The wave may also deteriorate and/or reform based on the underlying topography of the pool floor. As illustrated, for example in
As illustrated, a first wave zone 36 is adjacent the wave generating chambers. The wave at this portion is at its highest. This area may be for the most experienced riders. It may also be for the short board riders.
As illustrated, a second wave zone 37 may be in an area of the pool after the wave leaves the chambers that runs along a sidewall or edge of the pool. The wave will dissipate energy and reduce height after the wave propagates away from the chambers. This area is therefore created for intermediate riders and longboard riders.
As illustrated, a third wave zone 38 may be adjacent the side of the pool away from the chambers. The edge may correspond to a shore area 46′ of the pool. This area may have a shallow depth and may have an inclined floor bottom. The third wave zone 38 may be for beginning wave riders. This area may also be used for boogie boards, foam boards, kayaks, or skimming boards. This area may also be used for body riding or wave jumping.
The bottom of the pool may have areas that correspond or influence the wave zones. For example, a first area 42′ of the pool bottom may generally correspond to the first wave zone 36, while a second area 44′ of the pool bottom may generally correspond to the second wave zone 37, and a third area 46′ of the pool bottom may generally correspond to the third wave zone 38. A fourth area 44′ and/or other areas may be used to generate and separate the different wave zones and/or be used to reform waves as the wave propagates from the chambers. The different areas of the pool floor are discussed more fully with respect to
The different floor bottom areas may be used to influence a wave profile. For example, the depth of the floor may influence a wave size, while the slope of the floor may affect the wave shape. The first area 42′ adjacent the chambers may therefore generate a wave zone 36 for the most experienced riders. This area may be approximately 2-6 meters deep. This area may have a floor bottom with a greater slope or incline toward the shore or opposing side of the pool and/or may have the greatest depth. The third area 46′ may be adjacent the shore or edge of the pool away from the chambers and may generate a wave zone 38 for the most inexperienced riders. This area may therefore have a floor bottom with the smallest slope or incline toward the edge and/or may have the shallowest depth. The gentler slope may make the wave brake softer.
In an exemplary embodiment, the edge of the pool away from the chambers may also be contoured to influence the wave characteristics. For example, in the area of the third wave zone, or the area for beginners, the edge may be elevated toward a middle of the pool, on an opposite side of the pool from the middle chambers of the sequence of chambers. This elevation may form a shore or dry indentation into the side of the pool. As the wave propagates across the pool from the chambers toward the shore, the wave may wrap around the elevation extending into the pool area. Other or additional elevations may be provided along the short to create additional wave zones. In an exemplary embodiment, an elevation may be used to separate and/or redirect a wave.
Referring to
As illustrated, the chambers may release water into the pool in sequence generating a wave. If the chambers first open at the middle of the sequence of chambers and then open sequentially in opposing directions toward each end, both left and right waves will propagate from the chambers and break at approximately the same time (assuming a mirror configuration of the pool). The chamber sequencing may also be delayed or offset, such that the left and right breaking waves may be staggered. The expert wave zone may be defined as an area adjacent or proximate the chambers. The wave within the expert wave zone may break along the wave-generating wall. The wave may retain an approximate constant height as the sequential release of water from the chambers may be used to maintain the wave formation. In an exemplary embodiment, the wave height in the expert wave zone may be approximately 1.5 to 3.5 meters (approximately 4 to 11 feet). After the wave leaves the area proximate the chambers, the wave will dissipate energy and the wave height will decrease. The wave extending along the side edge of the pool away from the chambers may form the intermediate wave zone with a wave height that is reduced from the expert wave zone. In an exemplary embodiment, the wave height in the intermediate wave zone may be approximately 1-2 meters (approximately 3 to 6 feet). The wave height may continue to decrease as it travels away from the chambers. The wave may thereafter break along the opposite side of the pool in the shallow area to create a beginner wave zone. In an exemplary embodiment, the wave height in the beginner wave zone may be approximately 0-1.5 meters (0 to 4.5 feet).
In an exemplary embodiment, a first area 42 may correspond to the area proximate the chambers 14. As seen in
In an exemplary embodiment, a third area 46 may correspond to the area on an opposite end of the pool form the chambers 14. The third area 46 may be on a side of the pool corresponding to an end of the wave travel that is opposite from the origin of the wave. The pool floor 56 of this area may have a more gradual slope than the slope of the area adjacent the chambers. The pool floor 56 may include a gradual slope upward such that the pool toward the first area 42 is deeper than the area on an opposite side thereof. The terminal end of this area may have a zero depth such that the water washes up the side to the surface of the wall. This area may approximate a beaching area. The slope may traverse from deeper to shallower moving across the area in a direction away from the chambers at an angle β. This area may correspond to a band or width at the terminal end of the wave at an opposing side of the pool from the chambers. As the chambers may generate a wave that propagates away from the chambers in an oblique angle and not directly perpendicular to a front face of the chambers, the opposing end of the pool may be offset and include a portion of the pool that ends past the lateral side end of the chambers. Opposite may therefore include directly or geometrically opposite as well as opposite based on the propagation of the wave generated from the chambers.
As illustrated, the third area 46 may be shaped in a curve such that portions of this area are further away from the chambers than other portions of this area. For example, the shore area 46′ may be curved such that portions adjacent the lateral side of the pool corresponding to the ends of the chambers and toward a middle of the shore (for a mirrored pool) or the opposite lateral side of the pool (for a single sided pool) are positioned closer toward the chambers than areas there between. As illustrated, the shore region or the side of the pool opposite the chambers may therefore include three curved regions, two outside regions on opposing ends of the shore region in which the region is concave with the inward concavity toward the chambers, and an interior curved region between the two outside regions in the middle of the shore region is convex with the outward concavity toward the chambers. The concave and/or convex shore areas may include curvi-linear sections. For example, the interior portion of the concave or convex curved shore section may be extended to approximate a linear interior section so that the curvature of the concave or convex portion is not constant through the curve.
As illustrated, a second area 44 may extend from the first area 42 to the third area 46. This area may be similarly sloped. The slope of the area may be linear, curvi-linear, or curved. This area may include a gradual slope that transitions the bottom surface from the first area 42 to the third area 44. This area may also be contoured to provide a transition to any other area that may be included in the bottom profile. The second area 44 may therefore provide a transitional surface between two or more other floor bottom surfaces or areas.
The pool may include one or more other floor areas defining one or more other zones. For example, the first wave zone may be separated from the third wave zone. The separation may be to create a floor profile to recreate a desired waveform. The separation may be to permit space between the various wave zones for rider safety and/or rider enjoyment. As seen in
In an exemplary embodiment, the gradient of the pool floor bottom 52 corresponding to a first area 42, 42′ is greater than the gradient of the pool floor bottom 56 corresponding to the third area 46, 46′ (α≥β). In an exemplary embodiment, the gradient of the pool floor bottom of the second area 46, 46′ is generally equal to either of or between the gradient of the first area and the second area (α≥θ≥ β). The pool floor bottom 52 may have a slope of between 3 and 10 degrees. The pool floor bottom 56 may have a slope of greater than 0 degrees to 5 degrees. The pool floor bottom corresponding to the second area 46, 46′ may have a slope of between 2 and 10 degrees.
The configuration, shape, elevation, slopes, and other features of the pool floor bottom described herein are exemplary only. Other or additional features may be added and are within the scope of the present description. For example, an additional sloped floor and/or one or more other level floor areas may also be included to create additional wave areas and/or separate wave areas. Other elements may also be included, such as floor configurations, walls, dividers, elevations, shore features, etc. to further enhance the surfing experience or to provide additional benefits to the pool wave generator described herein. These may include features for splitting, redirecting, reforming, or otherwise effecting the generated wave.
Conventional chamber configurations in which the chamber and pool share a common wall or in which the chamber and the pool are in close proximity create eddy currents through the area between the chamber and the pool. The eddy currents may interfere with the shape and stability of the generated wave. U.S. Pat. No. 10,526,806 discloses a vane positioned between or near the chamber and pool interface to control and direct the water movement and reduce the formation of eddy currents. Such systems create construction and maintenance costs as the vanes must be internally supported and maintained. Exemplary embodiments described herein permit the formation of a wave pool that may manage or reduce the formation of eddy currents without the use of a vane or an internal structure within or adjacent the water flow path between the chamber and pool.
The chamber 62 and the configuration of the chamber 62 to the pool 64 may be used to generate waves of desired characteristics. Exemplary embodiments use the chamber width CW and the width between the pool and the chamber (wall width) WW to control or influence the currents and waves generated by the chambers. In an exemplary embodiment, the width between the pool and the chamber, WW, is greater than 2 meters. The greater distance in this transition area between the chamber and the pool, however, can affect and reduce the height of a generated waved. Therefore, conventionally, it was desirable to keep this area as short as possible. This distance, however, can be used to reduce turbulence and create a better wave profile. In an exemplary embodiment, the distance between an edge of the pool and an edge of the chamber is between 2 and 7 meters (6 and 21 feet). The chamber width, CW, may influence the resulting height of the generated wave. Similar to the wall width WW, this dimension conventionally was reduced as the additional width necessitated additional power for controlling and releasing the wave. For example, additional gas would be needed to create the same pressure on the water surface. The chamber width CW is preferably 1.3 to 5 meters (approximately 4 to 15 feet).
In an exemplary embodiment, the chamber 62 may be coupled to the pool 64 by a passage 66. The passage may be positioned at a depth lower than the pool 64, such that water exits the chamber and enters the pool, on a bottom of the pool or adjacent to the bottom of the pool. The passage may be shaped such that the direction of water leaving the passage may have a vertical component. The passage may include an inner wall 68B and an outer wall 68A. The inner wall 68B and outer wall 68A may be curved to reduce turbulence imposed on the water as it passes through the passage from the chamber to the pool.
As described herein, the terminal end of the pool 64 toward the chamber may be separated by the chamber by a width WW. In an exemplary embodiment, the separation between the chamber and the pool may permit spectator observation. As illustrated in
In an exemplary embodiment, the separation between the chamber and the pool may permit storage of system components in addition to or in place of spectator observation. For example, the area between the pool 64 and the chamber 62, positioned over passage 66, may include the space for the air plenum, pump equipment, blowers, electronics, controllers, equipment room, or other system components. As illustrated, the bleacher or sitting area may incorporate an equipment room 86. The space under the floor 78 or otherwise positioned between the chamber and the pool may include other component parts, such as a space for the air plenum, electronics, controllers, or other equipment. As illustrated, the area between the pool and chamber includes a space for the air plenum 84 and behind the chamber 86 is positioned the electrical room.
In an exemplary embodiment, the space between the pool 64 and the area 72 between the pool and the chamber 62 may be open and/or unobstructed. In this case, a rider, swimmer, and/or lifeguard may be able to enter the pool area from the floor 78 on the wave generating side of the pool. In an exemplary embodiment, a wall 74 may extend beyond the height of the water to separate the space between the pool and the chamber from the pool itself. The wall 74 may be an extension of the side of the pool over the passage entrance. The wall 74 may be of an acrylic, plastic or other semi-transparent or transparent material to permit observation of the activities within the pool at a location outside of the pool. The wall 74 may protect observers from getting wet or accidentally falling into the pool.
An exemplary embodiment provided herein includes a pool wave generator, comprising a pool area, and a plurality of chambers on one side of the pool area for releasing water into the pool area to generate a wave in the pool area.
The plurality of chambers may include an interior wall on a side of the plurality of chambers toward the pool for separating water retained within the chamber from the pool. The pool may include a wall defining an edge of the pool on a side of the pool toward the plurality of chambers. The pool wave generator may also include a passage from each of the plurality of chambers to the pool, the passage creating a fluid flow path from an interior of a chamber to the pool area. The interior wall of the chamber may be separated from the wall defining the edge of the pool by at least 2 meters. A gap may therefore be defined by the separation of the interior wall of the chamber to the wall defining the edge of the pool. The gap may include a floor for supporting a spectator. Electrical equipment may be positioned within the gap. The gap may be positioned over the passage. The gap may not be in fluid communication with the pool, chamber, or passage.
The pool wave generator may also include a transparent wall extending above the wall defining the edge of the pool toward the plurality of chambers.
In an exemplary embodiment, the pool area may be defined by a first edge containing the plurality of chambers on one side of the pool area, a first lateral side extending from the first edge and extending away from the plurality of chambers, a second lateral side on an opposite side of the pool from the first lateral side and extend from the first edge and extending away from the plurality of chambers, and an opposite side edge of the pool area from the first edge. The first lateral side and the second lateral side may extend away from the chambers at an oblique angle. The oblique angle may be approximately 110 degrees to 160 degrees. The oblique angle may be approximately 130 degrees to 160 degrees.
The pool area of the pool wave generator may include a pool floor. The pool floor may be contoured to create different wave zones. The pool floor may include a first portion of the pool floor that is adjacent an edge of the pool area toward the plurality of chambers. The first portion may include a first tapered floor from the edge upward in a direction away from the plurality of chambers. The pool floor may include a third portion of the pool floor that is positioned adjacent an opposing edge of the pool area away from the plurality of chambers. The third portion may include a third tapered floor. The taper of the first tapered floor may be greater than an angle of the taper of the third tapered floor. The pool floor may include a generally flat transition section between part of the first tapered floor and the third tapered floor. The pool floor may include a second tapered floor, the second tapered floor may be positioned between the first tapered floor and the third tapered floor at a lateral side of the pool.
In an exemplary embodiment, the opposing edge of the pool area may be defined by the third tapered floor being elevated to the height of the water to similar a beach shore. The opposing edge of the pool area may include an elevated region such that the opposing edge of the pool area at a height of the water defines a curved shape. The curved shape may include three curves: two concave curves on opposing ends of the opposing edge of the pool area, and a convex curve positioned between the two concave curves, wherein a concavity of the curves is from a perspective of the plurality of chambers.
In an exemplary embodiment, the pool area may include a shore edge. The shore edge may be an opposite side edge of the pool across from the chambers. The opposite side edge of the pool area may define two lobe areas. Each of the two lobe areas may comprise a concave curved section in relation to the interior of the pool. The opposite side edge of the pool area may be created by a sloping elevation of the floor to create the opposite side edge. The opposite side edge of the pool area may have an elevation of the floor at water level defining the opposite side edge that is positioned closer to the plurality of chambers in an area toward the middle of the opposite side edge and has an elevation of the floor at water level positioned further away from the plurality of chambers in an area toward a side of the opposite side edge.
In an exemplary embodiment, the pool wave generator may comprise any combination of a pool means for retaining water within an area for simulating a wave environment, a shore means for approximating a beaching area of the pool; a wall means for retaining water within the pool area for influencing waves, currents, water propagation, or combinations thereof within the pool area, chamber means chamber means for retaining and releasing water into the pool area to generate a wave in the pool area, and/or passage means for transitioning water from the chamber means into and out of the pool means.
Exemplary embodiments of a pool means for retaining water within an area for simulating a wave environment can include any structure described herein or any structure that is equivalent thereto. For example, the pool means may be a sufficiently strong structure for creating a cavity or enclosure for retaining water within an area. The area may not be fully defines, such as in the case of a tapered floor extending upward from below water level to above water level and waves being generated thereon. The pool area may therefore be dynamic based on the water position. The pool means may be, for example, a concrete structure. The concrete structure may be internally and/or externally reinforced.
Exemplary embodiments of a shore means for approximating a beaching area of the pool can include any structure described herein or any structure that is equivalent thereto. The shore means may, for example, be a portion of the pool means including a wall that tapers or extends upward from below water level to above water level on one or more sides of the pool area. The shore means may be positioned across from the pool area from the chambers.
Exemplary embodiments of a wall means for retaining water within the pool area for influencing waves, currents, water propagation, or combinations thereof within the pool area can include any structure described herein or any structure that is equivalent thereto. For example, the wall means may include portions of the shore means. The wall means may include contours within the elevation of the wall approximates the height of the water at different locations along the wall means and/or at different positioned away from the chambers. The wall means may include a portion that is positioned closer to the chambers at one location or along a stretch of the wall means and then includes one or more portions that extend away from the chambers so that the water is propagated around an indentation created by the wall means. The wall may include lateral side walls that extend from opposing ends of the chambers and extend away from the chambers at an oblique angle thereto.
Exemplary embodiments of chamber means for retaining and releasing water into the pool area to generate a wave in the pool area can include any structure described herein or any structure that is equivalent thereto. The chamber means may include different combinations of valves for retaining and releasing water from the chamber. The chamber means may include different combinations of valves for evacuating and/or injecting gas out of and into the chamber. The chamber means may control the water strictly by controlling the ingress and egress of gas into the chamber. The chamber means may control the water strictly by controlling the ingress and egress of water into the chamber. The chamber means may control the water by a combination of controlling the gas and water into and out of the chamber.
Exemplary embodiments of the passage means for transitioning water from the chamber means into and out of the pool means can include any structure described herein or any structure that is equivalent thereto. The passage means may include a passage in fluid communication between the pool area (or pool means) and the chamber (or chamber means). The passage means may be an elongated passage between the pool and the chamber. The passage means may include curved walls. The passage means may be in fluid communication with a bottom of the chamber and/or with a bottom or through the floor of the pool. The passage means may include a horizontal section to traverse a gap created between the chamber and the pool. The horizontal section may be more equal to or greater than 2 meters (6 feet).
