Definitions

  • This invention relates in general to water rides, specifically a mechanism and process that: 1) will safely transfer the kinetic energy of a high speed water flow to participants riding/sliding (with or without a vehicle) upon a low-friction surface and enable them to accelerate in a downhill, horizontal or uphill straight or curvilinear direction; 2) will safely stabilize and equalize the coefficients of friction and trajectory of differently sized and weighted participants on a water ride with a steep downhill portion followed by a subsequent significant uphill portion; and 3) will permit self-clearing of the transitory surge/hydraulic jump that may occur on a horizontal or upwardly inclined water ride flume.
  • the current genre of water ride attractions e.g., waterslides, river rapid rides, and log flumes, require participants to walk or be mechanically lifted and water to be pumped to a high point, wherein, gravity enables water rider(s), and riding vehicle (if appropriate) to slide down a chute or incline to a lower elevation splash pool, whereafter the cycle repeats.
  • Gravity or gravity induced rider momentum is the prime driving force that powers the participant down and through these traditional water ride attractions.
  • a novel aspect of the subject invention is the employment of a high speed jet of water to propel a participant in lieu of, or in opposition to, or in augmentation with the force of gravity.
  • water ride attractions have not utilized the water that is pumped in a horizontal or downward direction as the object and driving mechanism for accelerating a rider down or along a run.
  • water ride attractions to date have not used jetted water to propel a rider up an incline to a higher elevation.
  • the embodiments of the invention described herein will permit a rider(s) on the surface of a water attraction: to accelerate downhill in excess of the acceleration attributable to the force of gravity (said embodiment is hereinafter referred to as the "Downward Accelerator”); or to accelerate in a horizontal direction, (said embodiment is hereinafter referred to as the “Horizontal Accelerator”); or to accelerate in an uphill direction (said embodiment is hereinafter referred to as the "Upward Accelerator”; or to slide downward on a conventional slide and enter a flow of water of equal or slower speed and yet return in an upward direction to a higher elevation that is equal to or less than that which could be achieved through using gravity alone (said embodiment is hereinafter referred to as the "Stabilization/Equalization Process” ,or to slide downward on a conventional water ride attraction and return in an upward direction to an elevation higher than that which could be achieved through using gravity alone (said embodiment is hereinafter referred to as the "Elevation Enhancement
  • Meyers U.S. Pat. No. 3,923,301, issued Dec. 2, 1975 discloses a method of adapting a hill to provide a waterslide dug into the ground wherein a rider from an upper start pool slides by way of gravity passage upon recycled water to a lower landing pool.
  • the structure and operation of Meyers has no relevance to the present invention.
  • Timbes U.S. Pat. No. 4,198,043 issued Apr. 15, 1980 discloses a modular molded plastic water slide wherein a rider from an upper start pool slides by way of gravity passage upon recycled water to a lower landing pool.
  • the structure and operation of Timbes has no relevance to the present invention.
  • Becker, et al. U.S. Pat. NO. 4,196,900 issued Apr. 8, 1980 discloses a conventional downslope waterslide with simplified support construction involving a reduced number of parts at reduced cost with a conventional water pipe leading from a pump to the beginning of each slide. Becker goes on to suggest that such water pipe may include thrust nozzles at the top giving an extra push component to a person sitting there, thus making sure that a person, once boarded, does not block the slide by remaining in place. (Column 2, Lines 34 - 39). Becker's suggestion is customary to the entry tub of most conventional waterslides.
  • Becker's suggestion does not contemplate the performance characteristics as described by the present invention, i.e., downhill acceleration in excess of the acceleration attributable to the force of gravity, or acceleration in a horizontal direction in excess of that force which is necessary to prevent entry tub blockage, or acceleration in an uphill direction, or elevation recovery, or multiple propulsion locations, etc.
  • the "extra push" suggested by Becker is limited in location to the start of a slide, and limited in force to that which is necessary to avoid slide blockage by a starting slider.
  • the flow of water as injected by the subject invention is preferably located downstream of the conventional start as suggested by Becker.
  • a preferred function of the subject invention is acceleration of a rider who is already in motion, not one who is blocking the slide by remaining in place.
  • the suggestions of Becker are limited to existing conventional waterslide start basins, and as such, have no relevance to the present invention.
  • Goldfarb et al. U.S. Pat. No. 4,778,430 issued Oct. 18, 1988 discloses a waterslide toy wherein a mechanically powered conveyor lifts humanoid slide-objects from a lower slide section to the upper end of the slide section whereupon the slide-objects slide downward by way of gravity passage upon recycled water to the start point of the conveyor.
  • the structure and operation of Goldfarb et. al. has no relevance to the present invention.
  • Dürwald et al. U.S. Pat. No. 4,392,434 issued Jul. 12, 1983 discloses a turbulent waterway having boats guided in a trough between an uphill starting point and a downhill terminus and a chain conveyor that prohibits slippage as it carries the boats from terminus to start.
  • the structure and operation of Dürwald et. al. has no relevance to the present invention.
  • Moody U.S. Pat. No. 4,805,896 issued Feb. 21, 1989 discloses a water ride for swimmers which utilizes the linear (predominantly horizontal or downward) movement of a large quantity of water of swimming depth. Moody shares an attribute of the "Downward or Horizontal Accelerator" embodiments of the subject invention, i.e., the ability to move a participant in a predominantly horizontal or downward direction wherein the participant is moved by the water rather than through it. However, Moody can be distinguished from the subject invention as follows: The entire thrust of Moody is to provide a massive weight of water with very gradual downhill slopes to create desired swimmer movement.
  • the ride is comprised of a large quantity of water of with a weight substantially greater than the weight of the participant and at depth sufficient to prevent the floating or swimming participant from contacting the bottom of the water channel.
  • Moody specifies "High volume pumps at low water heads", (Column 3 Line 27).
  • the preferred embodiment for the subject invention utilizes lower volume pumps at higher water heads.
  • Such high head pumps in concert with properly configured nozzles produce powerful focused water flows that can function at less than one inch deep. A fortiori, swimming is not a requirement, and the participant will inherently touch the bottom surface over which he/she is sliding.
  • the volume of water required to move a participant per Moody is ten to twenty times greater than that which would be required by a preferred embodiment of the subject invention.
  • Moody uses a sufficient quantity of water to partially float the rider who can then accelerate by the relatively low kinetic energy of the slow moving mass of water.
  • the subject invention allows for acceleration by water impact (i.e., extreme momentum transfer), and does not require rider flotation to reduce the friction force.
  • a further significant point of differentiation includes the ability to propel the participant in an upward direction (such ability was not contemplated by Moody). As a result of these differences, it is respectfully submitted that Moody teaches away from the propulsion mechanism as taught by the subject invention.
  • Barber U.S. Pat. No. 4,836,521 issued Jun. 6, 1989 discloses an amusement device that incorporates a circular pond in which water is rotated by jets to form a vortex and wherein a rotating member with resultant centrifugal force gives the rider the sensation of traversing the edge of a giant whirlpool.
  • the structure and operation of Barber has no relevance to the present invention.
  • Dubeta U.S. Pat. No. 4,805,897 issued Feb. 21, 1989 discloses improvements to water slide systems, wherein a vertically rising water reservoir located at the upstream end of a waterslide (preferably at the beginning of the run) is properly valved to discharge a sudden quantity of water at selected intervals into the chute of the downwardly inclined waterslide. Similar to Moody (supra), Dubeta shares an attribute of several embodiments of the subject Invention, i.e., the ability to move a participant in a predominantly downrun direction wherein the participant is moved by the water rather than through it.
  • Dubeta can be distinguished from the subject invention as follows: The entire thrust of Dubeta is to increase rider safety by providing intermittent floods of water that assures proper spacing for riders on a downhill waterslide run. Dubeta clarifies; "because the flood occurs with each rider and the rider is carried thereby in a positive manner for the entire run of the slide...the riders on the slide are maintained at a spaced relation relative to one another on the slide as they proceed down the same. This overcomes many of the accidents that occur with the constant flow rate system as previously discussed.” (Column 6, Lines 57 - 64).
  • Dubeta the flood of water released by Dubeta is intended to move at substantially the same rate as the design speed of the rider sliding down the flume (see also Column 5, Line 14 - 18).
  • Dubeta's preferred embodiment utilizes a storage reservoir with seven feed of head (Column 5, Line 31). Functionally, this low head flood of water insures that the rider is carried by the flood "in a positive manner for the entire run of the slide".
  • the preferred embodiment of the subject invention does not require any mechanism or need to release gushes of water that flow in spaced relation one after the other down the slide, rather, constant flows of water can also function to perform the intended objectives.
  • the subject invention's accelerator embodiments preferably utilize head pressures in the range of 1.5 to 15 times as large as Dubeta.
  • head pressure in concert with properly configured nozzles produce powerful focused water flows that result in an acceleration and in velocities that are greater than one could ever achieve by just sliding down a flume (with or without a Dubeta gush of water).
  • Additional significant points of differentiation include the subject invention's ability to function without Dubeta's requirement of a vertically rising water tower reservoir at some location upstream from the end of the slide, and, the subject invention's ability to propel the participant in a horizontal or upward direction (such ability was not contemplated by Dubeta).
  • a participant in a Dubeta improvement will always be positioned downstream of the flood releasing valve prior to valve opening and gush production.
  • the propellant water is already flowing at such time that the participant enters its stream.
  • Atlantic Bridge Company British Pat. No. 1,204,629 discloses a conveyance device for fragile articles, e.g., fish or produce, wherein said articles are moved at a high rate of speed by way of suction and gravity and are decelerated with minimal damage by introducing said articles into a liquid bath at an acute angle so that the articles meet the liquid surface obliquely with reduced shock of impact.
  • the structure and operation of Atlantic Bridge Company has no relevance to the present invention.
  • Frenzl U.S. Pat. No. 3,598,402 issued Aug. 10, 1971 is perhaps more closely related in structure to the "Upward Accelerator" embodiment of the present invention than any of the previously discussed references.
  • Frenzl discloses an appliance for practicing aquatic sports such as surf-riding, water-skiing and swimming comprised of a vat, the bottom of which is upwardly sloping and has a longitudinal section which shows a concavity facing upwards while a stream of water is caused to flow upslope over said bottom as produced by a nozzle discharging water unto the surface of the lower end of said bottom.
  • Frenzl '402 does not recognize, either explicitly or implicitly some of the problems solved by the present invention, among which is the use of the upwardly flowing water as the means to thrust a rider up an incline and beyond the flow generating apparatus.
  • Frenzl teaches in the instance of "torrential flow” that the function of his structure, "allow(s) the practicing of surf-riding and other similar sports, as the sloping of the vat bottom results in the possibility for the water skier to keep his balance in an equilibrium position depending on the one hand, on an upwardly directed force ascribable to the drag or resistance of the carrier board or boards dipped into the stream of water and, on the other hand, on a downwardly directed force produced by the component of the weight of the water skier in a direction parallel with the vat bottom.” (Frenzl, Col. 1 lines 49 - 57).
  • Frenzl In the instance of a “river type flow”, Frenzl teaches that the function of his structure, “allows also practicing swimming. To this end, the swimmer sets the bottom 1 into a slightly sloping position... and he fills the vat almost up to its upper edge. He resorts then to low speeds for the water stream... The stream of water may be adjusted, so as to match the speed of the swimmer" (Frenzl, Col. 4 lines 14 - 22).
  • the entire teaching of Frenzl is for the user of the apparatus to be in equilibrium so that the aquatic sport can be practiced by the user. Either a user is in static equilibrium while skimming the surface of the water or in static equilibrium when swimming through the water. All adjustments to the appliance are directed at creating or sustaining this equilibrium.
  • the teaching of the present invention is to avoid equilibrium.
  • a rider who achieves equilibrium would oppose the objective for which the ride was designed, i.e., to propel its user up an incline and beyond.
  • equilibrium is a safety hazard in that other riders who enter the device and are propelled upward could collide with a rider who is in equilibrium.
  • Frenzl's structure was designed for equilibrium, and as such, teaches away from the propulsion mechanism as claimed by the subject invention.
  • Frenzi U.S. Pat. No. 4,905,987 issued Mar. 6, 1990 shows improvements to the appliance disclosed in the Frenzl '402 patent (described above) and in addition shows connected areas for swimming, non-swimming and a whirlpool so that water from the Frenzl '402 appliance is further utilized after outflow thereof.
  • the primary objective of the Frenzi '987 patent is to improve the start and exit characteristics of the Frenzl '402 appliance by providing a means whereby a user can enter, ride, and exit the appliance to avoid breakdown of the torrential flow.
  • Frenzi does not contemplate user movement from the '402 portion of the structure to other portions (e.g., swim channel or whirlpool) of his device.
  • Frenzi describes a catch grate as a vertical terminator that prohibits movement of a user and his riding equipment to other portions of the flow system.
  • Frenzl U.S. Pat. No. 4,564,190 issued Jan. 14, 1986 shows improvements to the appliance for practicing aquatic sports using gliding devices (as disclosed in the Frenzl '402 patent) by introduction of a device that removes water from an upwardly sloping bottom surface which has been slowed down by friction at the boundary faces and returns the water to a pumping system to thereby increase the flow rate and thus eliminate the deleterious effects of slowed down water.
  • Frenzl '190 is quickly distinguished from the subject invention on two bases. First, the structure and operation of Frenzl '190 is limited to an appliance for practicing aquatic sports using gliding devices.
  • Bacon '161 has no relevance to the present invention.
  • Bacon U.S. Pat. No. 3,853,067 issued Dec. 10, 1974 discloses a boat amusement ride wherein water is pumped to a channel at the top of the ride, passengers in boats are mechanically conveyed to this top water channel, the boats guided by the walls of the water channel float to a steep down chute portion, the boats individually descend to the rides low point and then recover significant elevation within a common trough with the water.
  • a dam is provided at the top of the downchute. When enough water is accumulated behind the dam it is opened and the mass of water travels along the downchute and up the subsequent rise portion, thus "priming" the ride.
  • Bacon '067 appears very similar to the "Stabilization/Equalization Process", “Elevation Enhancement Process” and “WaterCoaster” embodiments of the subject invention, however, there are four significant structural and functional distinctions.
  • Bacon '067 is limited to a "boat amusement ride". The subject invention has no such limitation, riders sliding in bathing suits without the aid of a "boat” type riding device will also function admirably.
  • Second, the water in Bacon '067 is introduced only at the "top at the beginning of the ride" (see column 2 line 36). In the subject invention, water is introduced after the rider has attained an initial start velocity in the conventional manner as known to those skilled in the art. Such introduction is by definition not at the beginning of the ride.
  • Bacon identifies and proposes a solution to the problem of carrying water through the rising portion of the trough especially during she rides start mode
  • Bacon introduces a cam at the top/start of the ride. When enough water has accumulated behind this dam it is opened and the mass of water travels along the downchute and up the subsequent rise portion, thus 'priming' the ride.
  • the subject invention solves the problem associated with upward water flow during the start mode by either introducing vents or reconfiguring the riding surface to facilitate water clearing in the subsequent rise portion of the ride. For the above stated reasons it is respectfully submitted that Bacon 067 teaches away from the subject invention.
  • JP-A-63-309 290 discloses an amusement device having a trough shaped waterway wherein at least a bottom surface thereof is smooth. Jet parts are provided at the bottom surface for ejecting a jet stream, for impelling a human body that can be moved into the water stream. The jet stream is ejected into the waterway obliquely in connection with the flowing direction.
  • the primary objective of the present invention is to provide a safe, entertaining and functional water ride in which participants are propelled in a downward, horizontal or upward direction by means of a high velocity flow of water.
  • participant will be able to ride in a horizontal direction and accelerate without the requirement of losing one's vertical elevation. More uniquely, a participant will be able to slide uphill, akin to a waterslide in reverse. Furthermore, due to the force of the propellant water, the participant can be made to achieve a height that is in excess of the initial start height.
  • a water powered escalator ie. enabling participants to move to higher elevations without the need of climbing stairs (as is currently the norm in most water recreation facilities). Additionally, this embodiment could be configured to permit handicapped individuals who cannot climb stairs to enter and ride a water oriented sliding attraction starting from the ground level.
  • a second objective of the present invention is to inject non-accelerating flows of water into a water ride that recovers in elevation following the bottom of a downchute portion.
  • Such injection has the advantage of providing a stabilizing influence for the rider/vehicle, especially those instances where rider/vehicle coefficients of friction may vary.
  • a third objective of the present invention is the design of a water ride flume that will not only allow upward rider/vehicle movement, but will concurrently function to solve the transient surge problems associated with ride start-up and slow rider transitioning upon upwardly inclined riding surfaces.
  • a fourth objective of the present invention is to connect the present invention with a standard water slide/ride; and, in series to create a water slide/ride configuration that is akin to a rollercoaster.
  • This "Water Coaster" attraction has advantage over existing water slides (and even existing roller coaster rides), in that the continuation (kinetic energy) of a slider's ride is not limited to the initial potential energy gained from climbing to the top of the slide. Rather, by timely interjection of a properly configured high speed jet of water, the kinetic energy of said jetted water can transfer and accelerate a rider to enable the rider to attain an altitude (increased potential energy) in excess of an altitude that would be achieved absent said jetted flow.
  • the degree to which a rider will achieve "excess altitude" is a function of the velocity and amount of water that contacts and remains in contact with the rider during the course of his ascent.
  • a rider Upon reaching his apogee a rider transitions and either is blasted by another jet to continue his ascent, or is blasted horizontally, or, the rider descends along a path and in the manner of a standard water slide/ride to either a standard splash pool/transition zone, or to another jetted flow of stabilizing or accelerating water.
  • the Water Coaster embodiment can include all the standard twists, turns, jumps, and loops normally associated with a Roller Coaster.
  • a fifth objective of the present invention is to create a ride out of water that is ordinarily pumped uphill in an enclosed pipe.
  • the advantage of such an improvement is that it more efficiently makes use of an existing condition, i.e., if water is going to be pumped uphill in any event, (e.g., to service a fountain, waterslide or other gravity enhanced water attraction), then, one can obtain the benefit of riding (at minimal extra cost) such water that is already being upwardly pumped.
  • the subject invention is comprised of several embodiments that can stand alone or be combined to function for the recreational purposes as described herein.
  • a modular approach has been taken to define a set of common elements that are central to each embodiment.
  • the module is only grouped for purposes of convenience and is not intended to limit the scope of the invention, or the structure or function of the respective components that comprise the module.
  • the size of the components that comprise a module is a function of intended use.
  • the preferred embodiments as hereafter described are intended for single participant use, akin to the common waterslide. It is understood by those schooled in the art that with proper upsizing the subject invention could also accommodate multiple riders simultaneously.
  • the subject invention could service single or multi-passenger sliding vehicles, wheeled vehicles, or boats, thus allowing participants to become bathing suit wet or remain street clothes dry.
  • a propulsion module 21 comprised of a high flow / high pressure water source 22 ; a flow control valve 23 ; a flow forming nozzle 24 with adjustable aperture 28 ; a discrete jet-water flow 30 with arrow indicating the predetermined direction of motion; and a substantially smooth riding surface 25 over which jet-water flow 30 flows.
  • Module 21 is made of suitable materials, for example, resin impregnated fiberglass, concrete, gunite, sealed wood, vinyl, acrylic, metal or the like, and is joined by appropriate water-tight seals in end to end relation.
  • FIG.1C side view depicts a rider 29 (with arrow indicating the predetermined direction of motion) sliding upon a series of connected modules.
  • Connections 26a , 26b and 26c between modules 21a , 21b , and 21c permit an increase in overall length of the subject invention as operationally, spatially, and financially desired.
  • Connection 26 can result from bolting, gluing, or continuous casting of module 21 in an end to end fashion.
  • the riding surface 25 of each module need be substantially in-line with and flush to its connecting module to permit a rider 29 who is sliding thereon and the jet-water 30 which flows thereon to respectively transition in a safe and smooth manner.
  • Module 21 can also be connected in the conventional manner to standard waterslide or water-ride attraction flumes as currently exist in the art.
  • Module 21 length can vary depending on desired operational performance characteristics and desired construction techniques or shipping parameters.
  • Module 21 width can be as narrow as will permit one participant to ride in a seated or prone position with legs aligned with the direction of water flow [roughly .5 meters (20 inches)], and as wide as will permit multiple participants to simultaneously ride abreast or a passenger vehicle to function.
  • the driving mechanism which generates the water pressure for the water source 22 can either be a pump or an elevated reservoir. Where a series of modules are connected, a single high pressure source or pump with a properly designed manifold could provide the requisite service, or in the alternative, a separate pump for each module could be configured.
  • the line size of the water source 22 need be of sufficient capacity to permit the requisite configuration and pressure of jet-water flow 30 to issue from nozzle 24 .
  • the water pressure at nozzle aperture can vary depending upon desired operational characteristics. In a single participant waterslide setting, nozzle pressure can range from approximately 0.345 bar to 17.241 bar (5 psi to 250 psi) depending upon the following factors: (1) size and configuration of nozzle opening; (2) the weight and friction of rider relative to the riding surface; (3) the consistency of riding surface friction; (4) the speed at which the rider enters the flow; (5) the physical orientation of the rider relative to the flow; (6) the angle of incline or decline of the riding surface; and (7) the desired increase or decrease in speed of rider due to flow-to-rider kinetic energy transfer.
  • nozzle pressure range can be higher or lower given that vehicles can be designed to withstand higher pressures than the human body and can be configured for greater efficiency in kinetic energy transfer.
  • the flow control valve 23 is used to adjust pressure and flow as operational parameters dictate and can be remotely controlled and programmed.
  • Nozzle 24 is formed and positioned to emit jet-water flow 30 in a direction substantially parallel to and in the lengthwise direction of riding surface 25 through adjustable aperture 28 . To enable continuity in rider throughput and water flow, when modules are connected in series for a given attraction, all nozzles should be aligned in the same relative direction to augment rider movement.
  • Riding surface 25 need be of sufficient structural integrity to support the weight of a human rider(s), vehicle, and water moving thereupon.
  • Riding surface 25 have a low-coefficient of friction to enable jet-water 30 to flow and rider 29 to move with minimal loss of speed due to drag.
  • the condition of jet-water flow 30 i.e., temperature, turbidity, Ph, residual chlorine count, salinity, etc.
  • the condition of jet-water flow 30 is standard pool, lake, or ocean condition water suitable for human swimming.
  • Nozzle 24 dimensions are a function of available water flow and pressure and the desired performance and capacity characteristics of the module as further described herein.
  • FIG. 2 shows a perspective of the preferred embodiment for a nozzle 24 sized to perform for a single participant flat bottomed waterslide module. Curved bottom riding surfaces would perform more efficiently with bottom originating nozzle 24 and Aperture 28 conformed to the cross-sectional curvature of the curved riding surface. Aperture 28 of nozzle 24 can either be fixed or adjustable.
  • the preferred embodiment uses an aperture capable of adjustment. Ideally, adjustment should allow for variations in thickness and width of jet-water flow 30 .
  • the breadth c of nozzle aperture 28 can range from 1/2 cm to 40 cm.
  • the width d of nozzle aperture 28 can range from 20 cm to 200 cm.
  • a multiplicity of adjustment devices are capable of effecting proper aperture control, e.g., screw or bolt fastened plates, welded plates, valves, moveable weirs or slots, etc. Many of such devices are capable of automatic remote control and programming.
  • FIG. 2 shows in exploded view bolted aperture plate 31 fastened to adjust aperture opening to operational requirements. Although just one large nozzle 24 is illustrated, multiple smaller nozzles can be packaged to achieve similar flow and aperture size characteristics with satisfactory results. For multiple participant or large vehicle configurations, additional nozzles can be placed side by side to increase the horizontal flow area, or one large nozzle can function. It is also possible to vary the number and relative location of nozzle(s) 24 within a given module, so long as they serve to propel a rider or vehicle as contemplated herein.
  • Module 21 can function with or without channel walls. Furthermore, channel walls are capable of multiple configurations and can at times act as a riding surface.
  • FIG. 3A (top view) and FIG. 3B (perspective view) illustrates module 21 with right angle channel walls 27a and 27b .
  • FIG. 3C shows module 21 with channel walls 27c and 27d in a half-pipe configuration, with riding surface 25 and channel walls 27 integrated into the shape of a parabola.
  • Conventional channel wall shapes vary substantially between the ranges as described in FIG. 1A-C and FIG. 3 A-C. Functionally, when compared to a flat riding surface the addition of channel walls has three important advantages: First, as shown in FIG.
  • module 21 with properly configured channel walls 27e and 27f will allow the introduction of compound curves to the riding surface 25 that permit rider 29 and jet-water flow 30 to ride-up the side of the channel wall in a banking turn, oscillate between walls when coming out of the turn, yet stay within the riding surface region defined by the flume channel walls 27e and 27f .
  • a rider is limited to his initial direction of motion and would not be able to negotiate a turn unless acted upon by some outside force.
  • the second advantage for channel walls is their safety function, i.e., they keep a rider within the confines of the flume and prevent untimely rider exits and injury sustaining falls from an elevated riding surface.
  • channel walls can have the disadvantage of confining excess water and allowing an undesirable build-up that can adversely effect the operation of module 21 .
  • This undesirable build-up is particularly acute in an upward directed flow and occasionally a problem in a horizontally directed flow. In both cases, this build-up will most likely occur during three stages of operation, (1) water flow start-up with no rider present; (2) transferring the kinetic energy of the operating high speed flow of water to a slower speed rider; and (3) cumulative build-up of injected water from a series of nozzles along a ride course.
  • the transient surge will continue to build and if unrelieved will result in overall flow velocity decay, i.e., the slowed water causes additional water to pile up and ultimately collapse back onto itself into a turbulent mass of bubbling white water that marks the termination of the predominantly unidirectional jet-water flow.
  • kinetic energy transfer (2) when a slow rider encounters the faster flowing water, a transient surge builds behind the rider. Likewise, if this transient surge grows to large it will choke the flow of higher speed unidirectional jetted water, thus, causing flow decay.
  • Modules with no (or relatively low height) channel walls are self-venting, i.e., the slower water will escape to the sides.
  • vents to channel wall situations one can combine the aforementioned advantages of channel walls (i.e., tracking, structure and safety) with the self-venting properties of no channel walls and simultaneously solve the start-up, rider induced, and excessive accumulation transient surge problems.
  • FIG. 5A The first class, "porous vents", is illustrated in FIG. 5A wherein rider 29 is in an inclined module 21 with channel walls 27a and 27b . Jet-water flow 30 is already issuing from nozzle 24 when rider 29 enters its flow. Since the velocity of jet-water flow 30 is moving at a rate greater than the speed of the entering rider, a transient surge 33 will build behind the rider. This build-up can be eliminated by draining the slowed water through a porous vent 34a , 34b , 34c , or 34d along the sides of channel 27a and 27b or through porous vent 34e along the bottom of riding surface 25 .
  • Porous vents 34 must large enough to permit transient surge 33 to vent, yet not too large so as to adversely affect the safety or performance of a rider or riding vehicle that is moving over the surface 25 .
  • Acceptable types of porous vent openings include a multiplicity of small holes, a porous fabric, slots, grids, etc. The water once vented can be recirculated to the water source 22 .
  • the second class of vent mechanism to be used in module 21 can be described as an overflow vent or a "flume within a flume".
  • Two preferred embodiments specific to this class are hereinafter referred to as the Triple Flume and the Double Flume.
  • the Triple Flume has the advantage of permitting higher degrees of predominantly straight upward incline than the Double Flume, while the Double Flume has the advantage of permitting radical uphill curves that are not available to the Triple Flume.
  • the Triple Flume and the Double Flume are described in the context of module 21 , they are both capable of individual attachment to conventional non-injected water tides for the self-clearing purposes as previously described.
  • FIG. 5B shows a perspective view of a Triple Flume 35 self-venting improvement to module 21 .
  • FIG. 5C shows a cross-sectional Triple Flume 35 profile.
  • Triple Flume 35 is comprised of riding surface 25 and two adjacent overflow flumes 36a and 36b .
  • Riding surface 25 is integrated with or connected to two low rise channel walls 27f and 27g of approximately equal height.
  • Overflow flume 36a abuts and integrates, connects, or shares low rise channel wall 27f and on its opposite side integrates or connects to high channel wall 27h .
  • Overflow flume 36b abuts and integrates, connects, or shares low rise channel wall 27g and on its opposite side integrates or connects to high channel wall 27i .
  • Triple Flume 35 The orientation of Triple Flume 35 is predominantly at an upward incline with jet-water flow and rider moving in an upward direction on riding surface 25 , and any overflow water that spills into overflow flume 36a and 36b moving in a downward direction due to the force of gravity. Horizontal application of Triple Flume 35 is also appropriate in those circumstances where transient surge build up interferes with the smooth jet-water flow. However, during any horizontal application overflow flume 36a and 36b must maintain a sufficient degree of slope to permit overflow water to properly drain.
  • the heights of low channel walls 27f and 27g are variable depending upon a number of factors, e.g., the initial start-up water pressure and flow; the time required to achieve full operating water pressure and flow; the volume of riding surface 25 (i.e., riding surface width multiplied by wall height); the length and degree of incline of riding surface 25 ; the disparity of velocity between a slow entering rider and the higher speed flow; the flow volume of accumulating water; and design preference as to whether rider transfer from one flume to another is to be encouraged, etc.
  • the initial start-up water pressure and flow the time required to achieve full operating water pressure and flow
  • the volume of riding surface 25 i.e., riding surface width multiplied by wall height
  • the length and degree of incline of riding surface 25 the disparity of velocity between a slow entering rider and the higher speed flow
  • the flow volume of accumulating water design preference as to whether rider transfer from one flume to another is to be encouraged, etc.
  • the height of low channel walls 27f and 27g must be sufficient to separate the upward jet-water flow 30 from the downward overflow water 37 , as well as, facilitate tracking of a rider 29 substantially upon riding surface 25 .
  • low channel walls 27f and 27g must not exceed such height that will prevent the clearing of transient surge 33 . From a practical view point to avoid redundancy, low channel walls 27f and 27g will always be less than that which would be required for high channel wall 27h and 27i .
  • Overflow flumes 36a and 36b are of at least sufficient size to accommodate any overflow water 37 , and may also be increased in size to function as traditional downward oriented participant riding surfaces.
  • 5E, 5F, and 5G show in time lapse sequence how the design of Triple Flume 35 operates to solve the problem of a pressure/flow lag during start-up.
  • jet-water flow 30 has commenced issue in an uphill direction from nozzle 24 .
  • the leading edge of water flow is slowed down bye combination of the downward force of gravity and friction with riding surface 25 , whereupon, it is overtaken and pushed by the faster and stronger flow of water that subsequently issues from nozzle 24 .
  • the result of this flow dynamic is that a transient surge 33 begins to build.
  • transient surge 33 builds, it reaches the height of low channel walls 27f and 27g and commences to spill into overflow flumes 36a and 36b . Since overflow flumes 36a and 36b are at an incline, overflow water 37a and 37b flows downhill attributable to the force of gravity to porous overflow vents 38a and 38b , whereupon, it will drain and either be pump recycled to the water source 22 or used in some other fashion.
  • FIG 5F shows this start procedure moments later wherein the water pressure/flow rate from water source 22 or flow control valve 23 has increased and transient surge 33 has moved further up the incline. Overflow water 37a and 37b continues to pour in and run down to porous overflow vents 38a and 38b .
  • FIG 5G shows the final stage of start-up wherein the transient surge 33 has been pushed over the top of rising riding surface 25 and jet-water flow 30 now runs clear. Similar to the start-up procedure, when a lower speed rider encounters the higher speed water, or when an accumulative build-up of water results from a series of injected water flows, a transient surge may occur. In like manner, the transient surge will clear by spilling off to the overflow flumes and draining accordingly. Operationally, Triple Flume 35 is limited to predominantly straight sections since the height of the low channel walls 27f and 27g are insufficient to contain rider 29 to the inside slope of any significant arc's radius of curvature due to the centrifugal acceleration of rider 29 .
  • Triple Flume 35 has over existing art is its ability to achieve a smooth upward jet-water flow and retain this smooth jetted flow at high degrees of incline under a broad range of operating water flow variables.
  • FIG. 5H shows a perspective view
  • FIG. 5I shows a cross-section of a modified design of the overflow vent or "flume within a flume" self-venting embodiment, hereafter referred to as a Double Flume 39 .
  • Double Flume 39 is comprised of riding surface 25 and a overflow flume 36c .
  • Riding surface 25 is integrated or connected on one side to a low rise channel wall 27j and on the other side to a high channel wall 27k .
  • Overflow flume 36c abuts and integrates, connects or shares low rise channel wall 27j and on its opposite side integrates or connects to a high channel wall 27L .
  • Double Flume 39 does not vent as efficiently as Triple Flume 35 , and accordingly, is unable to achieve the high degrees of inclined steepness as Triple Flume 35 .
  • Double Flume 39 can be configured to permit high degrees of curvature with rider 29 being safely contained on the inside slope of high channel wall 27k .
  • FIG. 5J illustrates this ability of Double Flume 39 to allow upwardly inclined turns.
  • FIG. 5J shows rider 29 in varying stages of a turn on Double Flume 39 with portions of transient surge 33 spilling into overflow flume 36c , whereupon this overflow water 37c gravity drains to porous overflow vent 38c .
  • Double Flume 39 allows uphill turns as well as self-vent is a unique and significant advantage over the existing art.
  • the radius of arc, degrees of curvature, left or right orientation and turn-to-turn connectivity/oscillation that is attainable by Double Flume 39 is substantially similar to that which is currently in use by those skilled in the art of building and operating conventional downhill water rides.
  • the orientation of Double Flume 39 is predominantly at an upward incline with jet-water flow and rider moving in an upward direction on riding surface 25 , and any overflow water that spills into overflow flume 36c moving in a downward direction due to the force of gravity.
  • Double Flume 39 functions in a similar manner to solve the transient surge problems associated with ride start-up, rider transition, and water accumulation as Triple Flume 35 with the exception that overflow water 37c vents only on the one low rise side.
  • FIG. 5K, FIG. 5L and FIG. 5M illustrates in time lapse sequence how Double Flume 39 operates in the start-up situation to allow self-venting and facilitate the desired clear smooth flow. In this sequence, it can be observed that as jet-water flow 30 progresses up riding surface 25 , transient surge 33 builds and spills into overflow flume 36c , whereupon overflow water 37c gravity drains to vent 38c .

  • direction of entry for the vehicle or rider 29 is substantially aligned with the direction of jet-water flow 30 . Such alignment is particularly important in the Accelerator emodiments as described herein, so as to insure the most efficient water-to-rider momentum transfer.
  • jet-water flow 30 It is possible for a rider or vehicle to enter jet-water flow 30 in an unaligned manner or in direct opposition to its flow. Such entry will result in a larger transient surge and greater velocity reduction, however, care must be taken to avoid tumbling and injury that could result from the angled and impacting jetted water.
  • the final element of module 21 that requires description is the velocity of jet-water flow 30 as issued from nozzle 24 relative to the velocity of any object (e.g., a vehicle or rider 29 ) that slides into or enters jet-water flow 30 .
  • This "relative" velocity will vary depending upon the functional purpose of module 21 . If acceleration of an entering object is desired, then, the velocity of the water will be in excess of the object in the pre-determined direction of flow. This instance is further described in the following Horizontal, Upward and Downward Accelerator embodiments. If no acceleration or de-acceleration is desired, then, the velocity of jet-water flow 30 will be equal to or less than the velocity of the entering object.
