Definitions
- 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.
- 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.
- 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.
- the pneumatic wave generator uses water-filled caissons to produce the desired wave.

Description
- 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. 61/003,081 filed on Nov. 14, 2007, the entire disclosures of which are incorporated herein by reference.
- 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.
- Some embodiments of the invention provide an apparatus and method for creating an artificial wave for a river water ride with pneumatic wave generators enhanced by nozzles or jets. Embodiments of the invention provide an apparatus and method of forming an artificial wave that moves in a direction against current flow in a river water ride. 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. Some embodiments of the invention include a concave feature with a depression and a de-watering grate positioned upstream of the nozzles or jets.

FIGS. 1 and 2 illustrate awater ride 100 according to one embodiment of the invention. Thewater ride 100 can include one or more chambers orcaissons 1, aprimary pump room 2, and wave-generatingdevices 3. Thewater ride 100 can include water return grates 4,water return pipes 5, awater pump 7, a watersuction intake system 8, and asecondary pump room 9. Thewater ride 100 can include one or more sets ofstairs 14 that allow a rider to enter and exit thewater ride 100. In some embodiments, thewater ride 100 can be positioned adjacent to various commercial establishments or recreational activities, such as aconcession stand 10, ahot tub 11, or arestaurant 12. In some embodiments, a bar orwall 13 can be positioned within thewater ride 100 to divide thewater 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-generatingdevices 3 can be coupled to thewater return pipes 5 in order to use water flowing through the water return grates 4 to power the wave-generatingdevices 3. Thewater return pipes 5 can be connected to thewater pump 7. Thewater pump 7 can also be connected to the watersuction intake system 8. Thesecondary pump room 9 can supply thecaissons 1 with air and/or water to produce the primary wave of thewater 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 thecaissons 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 inFIG. 6 , a pattern ofnozzles 102 formed in a pipe can generate a wave at a startinglocation 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 thecaissons 1 to produce the primary wave. Thewater ride 100 can include one ormore caissons 1 positioned vertically along a back side of the pool. In other embodiments, thewater 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 thecaissons 1. The artificial wave generated by the wave-generatingdevices 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-generatingdevices 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, thewater 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 thecaissons 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 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. For a river water ride, the nozzles or jets can be configured to define water depths on the ride surface from approximately 24 inches to approximately 36 inches. - 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 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.
