Description

    RELATED APPLICATIONS
  • This application claims priority under 35 U.S.C. §119 to U.S. Provisional Patent Application No. 60/893,923 filed on Mar. 9, 2007, and U.S. Provisional Patent Application No. 61/003,080 filed on Nov. 14, 2007, the entire disclosures of which are incorporated herein by reference.
  • BACKGROUND
  • Wave pools and water rides often use conventional wave generators to produce waves. The design of the pool is very important for producing waves. If the design of the pool is flawed, the pool will not produce waves. Even in nature with the correct beach, perfect waves are rare, because the waves depend upon environmental conditions, such as tides, wind, and off-shore storms.
  • One conventional wave generator is the pneumatic surf wave. The pneumatic surf wave stores water in caissons and uses the water to produce the desired wave. The pneumatic surf wave uses gravity to discharge the water from the caissons. The pneumatic surf wave uses a fan to expel the air in the chamber, causing a vacuum to draw the air upward. When the air is at its maximum capacity, the air is released into the chamber to create the wave. The caissons of the pneumatic surf wave are generally positioned upright.
  • Another conventional wave generator is the surf wave generator. The surf wave generator uses compressed air to release water from caissons to form a wave. The surf wave generator uses rows of caissons positioned along a side of the pool. More specifically, the caissons of the surf wave generator are generally positioned vertically along a back side of the pool.
  • Yet another conventional wave generator is the pneumatic wave generator. The pneumatic wave generator uses water-filled caissons to produce the desired wave. The pneumatic wave generator uses compressed air to expel the wave from the caisson. The pneumatic wave generator includes many caissons in a single pool. The pneumatic wave generator includes caissons that are generally positioned vertically on a back side of the pool.
  • SUMMARY
  • Some embodiments of the invention provide an apparatus and method for creating an artificial wave for a water ride with pneumatic wave generators enhanced by nozzles or jets. Some embodiments of the invention provide a sheet flow wave generator including a ride surface and nozzles or jets coupled to the ride surface. The nozzles or jets can be configured to form an artificial wave upon the ride surface. Embodiments of the invention also provide an apparatus and method of forming an artificial wave that moves in a direction against current flow. An apparatus and method of making an artificial wave can include forming an artificial wave that moves in one direction and using current moving in another direction to slow the speed of the artificial wave. Some embodiments of the invention can also be used to make a standing wave that is suitable for recreational use by causing water to flow through nozzles or jets.

  • DETAILED DESCRIPTION
  • Before any embodiments of the invention are explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the following drawings. The invention is capable of other embodiments and of being practiced or of being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. The use of “including,” “comprising,” or “having” and variations thereof herein is meant to encompass the items listed thereafter and equivalents thereof as well as additional items. Unless specified or limited otherwise, the terms “mounted,” “connected,” “supported,” and “coupled” and variations thereof are used broadly and encompass both direct and indirect mountings, connections, supports, and couplings. Further, “connected” and “coupled” are not restricted to physical or mechanical connections or couplings.
  • FIGS. 1 and 2 illustrate a water ride 100 according to one embodiment of the invention. The water ride 100 can include one or more chambers or caissons 1, a primary pump room 2, and wave-generating devices 3. In some embodiments, the water ride 100 can include water return grates 4, water return pipes 5, a water pump 7, a water suction intake system 8, and a secondary pump room 9. The water ride 100 can include one or more sets of stairs 14 that allow a rider to enter and exit the water ride 100. In some embodiments, the water ride 100 can be positioned adjacent to various commercial establishments or recreational activities, such as a concession stand 10, a hot tub 11, or a restaurant 12. In some embodiments, a bar or wall 13 can be positioned within the water ride 100 to divide the water ride 100 into two or more sections.
  • The primary pump room 2 can include pumps positioned close to the surface of the pool in order to produce a current to propel riders. The wave-generating devices 3 can be coupled to the water return pipes 5 in order to use the water flowing through the water return grates 4 to power the wave-generating devices 3. The water return pipes 5 can be connected to the water pump 7. The water pump 7 can also be connected to the water suction intake system 8. The secondary pump room 9 can supply the caissons 1 with air to produce the primary wave of the water ride 100.
  • The wave-generating devices 3 can include pipes with nozzles or individual jets that force water upward to create a wave that moves in a direction against the current flow of the primary wave generated by the caissons 1. As used herein and in the appended claims, the terms “nozzle” and “jet” may be used interchangeably, with both terms referring to any device capable of propelling water upward from a surface in a desired direction and at a desired pressure. In one embodiment, as shown in FIG. 6, a pattern of nozzles 102 formed in a pipe can generate a wave at a starting location 15.
  • In some embodiments, additional wave-generating devices can be used to create a small non-curling wave or “bump” before a curling wave created by the wave-generating devices 3. This small non-curling wave can cause the rider to dip down before rising up the curling wave.
  • In some embodiments, the water ride 100 can use gravity to force water out of the caissons 1 to produce the primary wave. The water ride 100 can include one or more caissons 1 positioned vertically along a back side of the pool. In other embodiments, the water ride 100 can use a set wave system to generate primary and/or secondary waves as disclosed in applicant's co-pending U.S. utility patent application entitled “Set Wave System for Wave Generation,” the entire contents of which is herein incorporated by reference, and which also claims priority to U.S. provisional patent application No. 60/893,923.
  • The wave-generating devices 3 can be used to form an artificial wave that moves in a direction against current flow, such as the current flow produced by the primary wave generated by the caissons 1. The artificial wave generated by the wave-generating devices 3 can also move in a direction that is against the current flow of a river type of water ride that does not provide primary waves.
  • In some embodiments, as shown in FIG. 1, the artificial wave formed by the wave-generating devices 3 can move against the current flow in a channel (such as a stream or river, whether natural or artificial). The current flow in the channel can slow down the speed of the artificial wave. For example, in some embodiments, the current flow can slow down the speed of the artificial wave to about one-quarter of its original speed. In general, the water ride 100 can form an artificial wave that moves in one direction and can use current moving in another direction to slow the speed of the artificial wave.
  • In some embodiments, the wave-generating devices 3 include one or more nozzles or jets that can be used to change or enhance the shape of the artificial wave. In some embodiments, the nozzles or jets can be positioned beneath a surface of the water. In some embodiments, a series of nozzles or jets can be positioned on a floor of the water ride and can be used to change or enhance the shape of the artificial wave. For example, a series of nozzles or jets can be used to make the wave higher, steeper, and/or curl over. Also, a combination of nozzles or jets and current flow caused by the caissons 1 can be used to make the wave higher, steeper, and/or curl over.
  • In some embodiments, the water ride 100 can be used to make a standing wave that is suitable for recreational use by causing water to flow through nozzles or jets. In some embodiments, the nozzles or jets can be articulated or moveable to facilitate varying a shape of the standing wave.
  • As shown in FIGS. 3-5, some embodiments of the invention provide a sheet flow wave ride including a ride surface and a series of nozzles or jets coupled to, formed in, or positioned proximate to the ride surface. The nozzles or jets can be configured to form an artificial wave upon the ride surface. The ride surface can be generally planar. The ride surface can be positioned to be substantially horizontal or inclined with respect to the ground. The nozzles or jets can be configured to cause water to flow across the ride surface. If the ride surface is inclined, the nozzles or jets can be configured to cause water to flow upwardly over the ride surface. Depending on the intended use of the water ride, the nozzles or jets can be configured to define water depths on the ride surface from approximately 2 inches to approximately 36 inches. For a sheet flow water ride, the water depth on the ride surface can be substantially less than for a river type of water ride.
  • In some embodiments, the nozzles or jets are angled to cause the wave to curl forward on one side. The pressure of the water flowing through the nozzles or jets can be varied. For example, the pressure can be varied through each individual nozzle or jet or through groups of nozzles or jets. The water pressure can be varied through the nozzles or jets to change the shape and/or position of the wave. In some embodiments, the nozzles or jets can be articulated either in groups or individually. The nozzles or jets can be articulated to change the shape and/or position of the wave. In some embodiments, the water pressure can be varied through the nozzles or jets and the nozzles or jets can be articulated to move the wave left or right, move the wave up or down, and/or to vary the shape of the wave. In some embodiments, the water pressure is higher in the front (or lower or upstream) nozzles or jets than in the back (or higher or downstream) nozzles or jets. In some embodiments, a portion of the nozzles or jets are positioned along a front end (or lower end or upstream) of the ride surface to cause water flow upwardly across the ride surface. In some embodiments, a drain can be formed at the back end (upper end or downstream) of the ride surface.
  • FIG. 3A illustrates one embodiment of a sheet flow water ride 200 with a ride surface 202. The sheet flow water ride 200 can include wave-generating devices 3, additional wave-generating or flow-creating devices 4, a water suction intake system 8, and stairs 14. The wave-generating devices 3 can be used to create artificial waves on the ride surface 202. The wave-generating devices 3 can be configured in a number of manners, such as those shown in FIGS. 3B-3E. If the configuration of FIG. 3B is used, the artificial wave can be formed at a central portion 204 of the wave-generating devices 3. If the configuration of FIG. 3C is used, the artificial wave can be formed at a diagonal portion 206 of the wave-generating devices 3. If the configuration of FIG. 3D is used, the artificial wave can substantially span the width of the water ride 200. If the configuration of FIG. 3E is used, the artificial wave can be formed at another diagonal portion 208 of the wave-generating devices 3. In some embodiments, as shown in FIG. 3A, a bar or wall 13 can be positioned within the water ride 200 to create two ride surfaces for two riders. Each ride surface can include one of the nozzle or jet configurations shown in FIGS. 3B-3E.
  • FIGS. 4A-5E illustrate a water ride 300 similar to the water ride 200 shown in FIGS. 3A-3E, except that no bar or wall 13 is included in the water ride 300. As a result, the water ride 300 only includes a single ride surface 302.
  • In some embodiments, at least some of the nozzles of the wave-generating devices 3 are defined by openings formed in pipes. As shown in FIGS. 6-7, the openings in the pipes can spiral at least part of the way around the pipes in a rifling-like fashion. These types of nozzles can also be configured within the water rides described herein in the manner shown and described with respect to FIGS. 3A-5E.
  • FIGS. 8A-8D illustrate a water ride 400 according to another embodiment of the invention. The water ride 400 can include a body 402 divided into two or more parts, such as four parts 404, 406, 408, and 410, as shown in FIGS. 8A and 8C. More specifically, the body 402 can include an upper left body 404, an upper right body 406, a lower left base 408, and a lower right base 410. In some embodiments, each of the four parts 404, 406, 408, and 410 can be constructed of fiberglass. The water ride 400 can be substantially portable by disassembling and reassembling the four parts in a new location. In one embodiment, as shown in FIG. 8A, the assembled water ride 400 can have a length L of about 50 feet, a width W for each half of about 12 feet, and a maximum height H of about 7 feet. The upper left body 404 can be secured to the upper right body 406 using fasteners within holes 420 in flanges 422.
  • As shown in FIGS. 8A and 8C, the upper left body 404 and the upper right body 406 can include grating lips 412 that can support grating 414. In some embodiments, the upper left body 404 and the upper right body 406 can also include lateral grating 416 for de-watering the water ride 400 along its lateral sides 418.
  • In some embodiments, as shown in FIG. 8A, one or both of the upper left body 404 and the upper right body 406 can include stairs 424 that allow riders to enter and exit the water ride 400. In some embodiments, the upper left body 404 and the upper right body 406 can include a curb 425 formed around a bottom perimeter of the water ride 400.
  • One or both of the upper left body 404 and the upper right body 406 can include openings 426 (as shown in FIG. 8A) through which jets 428 (as shown in FIG. 8C) can be positioned. The jets 428 can propel a sheet of water up a ride surface 430. In addition to the jets 428, the water ride 400 can include a series of wave-generating devices 432, as shown in FIG. 8A, such as a series of pivot jets, that can propel water upward and/or in a direction that is against the current flow produced by the jets 428. FIG. 8B illustrates a wave-generating device 432 in the form of a pivot jet that can be articulated with respect to the ride surface 430.
  • FIGS. 8C-8D illustrate the jets 428 that propel water upwardly onto the ride surface 430. As the water moves up the ride surface 430, the water creates a sheet of water on the ride surface 430 flowing at a particular rate. Water is also being propelled upwardly from the wave-generating devices 432 positioned across the width W of the water ride 400. When the sheet of water meets the area adjacent to the wave-generating devices 432, the sheet of water is slowed down. The water being propelled upward by the wave-generating devices 432 combines with the sheet of water being propelled upward by the jets 428. As these two bodies of water meet, an artificial wave is generated on the ride surface 430. The shape, height, and curl of this artificial wave can be altered by varying the pressure and/or position of the wave-generating devices 432. The artificial wave can also be altered by varying the pressure of the jets 428. In some embodiments, the pressures and positions of the wave-generating devices 432 and the jets 428 can be automated with an automation system.
  • As shown in FIGS. 8C-8D, the water ride 400 can include grating 414 through which return water can flow once the sheet of water has passed over the ride surface 430. The return water can flow downward into a basin 434. As shown in FIG. 8D, the return water in the basin 434 can flow through water return grating 436 and into water intake ports 438 in order to be returned to the jets 428 through caissons 440. In some embodiments, the de-watering of the water ride 400 can also be accomplished using the lateral grating 416, as shown in FIGS. 8A and 8C.
  • FIG. 9 illustrates a water ride 500 according to another embodiment of the invention. The water ride 500 is similar to the water ride 400 shown and described with respect to FIGS. 8A-8D. In one embodiment, the water ride 500 can have a length L of about 52 feet and a total width W of about 34 feet. FIG. 9 illustrates an artificial curling wave 502 created by a combination of a sheet of water flowing from jets 528 up the incline of the ride surface 530 and water being propelled upward by jets 532 coupled to the ride surface 530. In some embodiments, the jets 532 can be coupled to the ride surface 530 in groups, with each group being positioned in a particular direction and propelling water at a particular pressure. For example, the jets 532 can be positioned in four rows across the width W of the water ride 500. In addition, the rows of jets 532 can create an angled portion across part of the width W of the water ride 500. The angled portion can be used to direct the curling portion of the artificial wave to the desired position on the ride surface 530.
  • FIGS. 10A-10C illustrate a water ride 600 according to another embodiment of the invention. The water ride 600 is similar to the water ride 400 shown and described with respect to FIGS. 8A-8D, except that the water ride 600 includes water intake ports 638 positioned along lateral sides 618 of the water ride 600, rather than under a ride surface 630 of the water ride 600.
  • As shown in FIG. 10A, a sheet of water is propelled up the ride surface 630 by jets 628. As the sheet of water flows up the inclined ride surface 630, the sheet of water can meet a first set of wave-generating jets 640 that can create a small non-curling wave or bump. The sheet of water can then met a second set of wave-generating jets 632 positioned across the width of the water ride 600. The jets 632 can create a curling wave, for example, as shown and described with respect to FIG. 9. The sheet of water can pass the jets 632 and continue up the inclined ride surface 630 until reaching the grating 614. As shown in FIG. 10B, the return water can fall through the grating 614 and be directed into a basin 634 and then toward the water intake ports 638 positioned along the lateral sides 618 of the water ride 600. The return water can be directed into chambers or caissons 642 (in one embodiment, three caissons 642 on each lateral side 618 of the water ride 600) and through additional piping 643 back to the jets 628. In some embodiments, a portion of the return water can be routed directly back onto the ride surface 630 by piping 644 (as shown in FIGS. 10A and 10B) rather than being returned to the jets 628.
  • FIGS. 11 and 12 illustrate an artificial curling wave created by a combination of a sheet of water flowing from jets up the incline of the ride surface and water being propelled upward by jets coupled to the ride surface. In some embodiments, the jets can be coupled to the ride surface in panels or groups (such as sixteen groups, as shown in FIGS. 11 and 12), with each group being positioned in a particular direction and propelling water at a particular pressure. For example, the jets can be positioned in four rows and four sections across the width of the water ride to create sixteen groups of jets. In addition, the rows of jets can create an angled portion across part of the width of the water ride. The angled portion can be used to direct the curling portion of the artificial wave to the desired position on the ride surface. In one embodiment, each panel or group can be about 24 inches long and about 7½ inches wide. Four panels can span about 96 inches across the width of the water ride. In another embodiment, each panel or group can be about 8 inches long, with four panels spanning about 32 inches across the width of the water ride in order to create a two foot high barrel standing wave.
  • FIGS. 13A-13J illustrate a wave-generating device 700 for use with the water rides shown and described with respect to FIGS. 1-12. The wave-generating device 700 can include groups of jets that can be operated, positioned, and/or pressurized in the same manner. FIG. 13A illustrates a top left group 702, a top right group 704, a top middle group 706, a bottom left group 708, a bottom right group 710, and a bottom middle group 712. By selectively controlling each of the groups of jets, the configurations shown in FIGS. 13B-13J can each be created. Each of the configurations shown in FIGS. 13B-13J can produce a different type, shape, or size of artificial wave. FIG. 13B illustrates the use of the top left group 702, the top middle group 706, and the bottom right group 710. FIG. 13C illustrates the use of the bottom left group 708, the top middle group 706, and the top right group 704. FIG. 13D illustrates the use of the bottom left group 708, the bottom middle group 712, and the bottom right group 710. FIG. 13E illustrates the use of the top left group 702 and the top right group 704. FIG. 13F illustrates the use all the groups except for the bottom middle group 712.

FIG. 13J illustrates the use of the top left group 702, the bottom left group 708, and the bottom right group 710.
  • FIG. 14 illustrates a wave-generating device 800 for use with the water rides shown and described with respect to FIGS. 1-12. The wave-generating device 800 can include a matrix 802 having a particular bed size. In one embodiment, the bed size is about 35½ inches by 20 inches. The matrix 802 can include a horizontal matrix 804 and an inclined matrix 806. The horizontal matrix 804 can include, for example, 66 jets (6 rows by 11 columns). The inclined matrix 806 can include, for example, 144 jets (6 rows by 24 columns). Accordingly, in one embodiment, the matrix 802 can include a total of 210 jets.
  • FIGS. 15A-15D illustrate wave profiles created with various embodiments of the invention.
