Said other surface is preferably formed of PVC. It will however be readily apparent to a person skilled in the relevant art that other materials could be used Instead of or as wall as PVC. 5atd other surface is preferably arranged to support one or more said persons upon completion, voluntarily or otherwise, of said surfing.

Said other surface Is preferably at least partially porous to facilitate drainage of fluid from said surface. Said other surface of said one aspect of said surfing device preferably comprises said Impact absorption material of said other aspect of the present invention. Said at least partially deformable other surface Is preferably arranged to at least partially enhance ride safety.

Said at least partially porous regions preferably comprise apertures. The apertures are preferably formed by two corresponding pairs of oppositely positioned dividers or strips that collectedly define rectangular shaped apertures.

For example, said partia lly porous surface of said surfing device, in one preferred form deforms quickly and the amount of deformation Is substantial, in an alternative preferred form said partially porous surface deforms more slowly and the amount of deformation Is less. Differences In deformation amounts and other de ormation cha racteristics may be provided, for example by different materials, material thicknesses or densities, or a combination of one or more of these.

Said cables preferably also at least partially absorb a fallen rider's Impact. In a preferred form of the present invention the cables loop under said other surface. The cables are therefore at least partially slack. In the event of said Impact of a fallen rider, this slackness enables the cables to at least partially move away from said rider proximal their point of impact. This away movement at least partially absorbs the Impact. However, the away movement also results In corresponding movement of said cable on either side of said rider and at least partial lifting of said other surface in regions on said either side. Said lifting preferably also contributes to said impact absorption In a preferred form by preferably lifting at least the weight of said other surface, In a more preferred form of the present Invention said cables minimally absorb seld fallen rider's Impact and said Impact Is primarily absorbed by said partially porous surface.

Said deformation Is preferably also arranged to at least partially enhance said surfing by temporarily reducing said fluid relief as said surfer surfs over said at least partially porous regions. The fluid relief Is preferably temporarily reduced by reducing porosity, in a preferred form of the present Invention porosity Is reduced by buckling of said slot edges and restricting or throttling of the corresponding apertures. A reduction In fluid relief increases the volume of fluid on said other surface which Increases upPft and in turn pushes a rider away from said other surface.

Another advantage of said temporary fluid relief reduction is that It at least partially reduces the rate of drainage of fluid drained from said other surfing surface. This reduction in drainage rate at least partially reduces energy usage of said surfing device by reducing the rate of projection of said projected energy required to enable said surfer to surf over said other surface at least partially solely via said projected energy.

Said modules preferably each comprise one or more of: at least a portion of said other surface; and at least one energy projecting outlet.

Said modification preferably most typically comprises one or more of: layout and In particular satd surface; or performance. However, said detachable feature may further be suitable for disassembling said device, moving disassembled components to another location and reassembling said device.

Said modules preferably further comprise one or more of said fluid relief and said floatation means. Satd energy projecting outlets are preferably spaced substantially evenly. However, due to said shape of said surface effective spacing ts at least partially variable for different regions of said surfing surface. The variable nature of said effective spacing creates a resolution effect on said projected energy. This resolution effect alters the effective 5 surface area of projection of said projected energy onto said surfing surface, in preferred embodiments ft effectively at least partially alters concentration of projected energy onto said surfing surface.

Said nozzles are preferably spaced In longitudinal direction substantially aligned with said longitudinal length a distance ranging from approximately 50 to approximately 300 mm. 0 Preferably said nozzles are spaced in a direction transverse to said longitudinal direction a distance ranging from approximately 250 to approximately 600 mm.

The surfer 70 therefore surfs 76 essentially free from any friction that would result from contact with the surface 80.

The surfboard 100 Includes contours of the present Invention which in this particular example comprise a waved underneath surface 110. Also included In the surfboard 100 are data means in the form of a processor 120 and corresponding respective data receiving and emitting terminals 124 and 128. As w!tl be readily appreciated by a person skilled in the relevant art emitting terminals 128 enable recorded data to be retrieved and analysed. The processor 120 and terminals 124 and 128 of this particular embodiment Is also designed for real time operation. The surfboard 100 also includes an at least partially stiff underneath portion which in this particular example is In the form of stiffened portion 134. A softened portion 136 is also Included and is one example of an at least partially soft upper portion.

As can be best seen in figure 3, the nozzles 20 and support structure 30 of this particular example are designed to simulate an ocean wave 200. The nonies 20 are positioned relative to each other to project fluid from uniform or seml-unlformly spaced positions of the surface 80. The projected fluid directs energy outwardly of the surface 80 from a position which can either be on or below the surface 80. Fluid is projected with sufficient force tD enable a rider using a planar object such as surfboard 100 to ride mostly free of any frlctional forces that would otherwise occur between the surfboard 100 and the surface 80.

Fluid 40 is projected at an angle ranging from approximately 10 to approximately 35 degrees relative to a tangential plane which is tangential to the surface 80, and values ranging from approximately ISOkgf per square meter to approximately 500kgf per square meter. However, mostly the fluid 40 Is projected generally uniformly both In terms of the angle and force of projection. The device 101s however designed so that It can Include segments (see for example figure 3 and segment 210 of that figure) that project fluid 40 at angles and forces generally different to those of other segments of the device 10. This variation enables the device 10 to more exactly simulate different surfing conditions experience at different points on a natural ocean wave. The range of projection angles Is represented by lines 220 and 230.

As is best shown In figure 7, fluid 40 Is also projected at a range of angles between approximately 135 and approximately 45 degrees relative to a front edge 82 of the surface 80. This second group of projection angles further enables the ride 10 to more exactly simulate real wave effects. Real wave effects alter dynamics of surfing and the surfing device 10 Is designed to simulate these effects to, for example, make the device 10 easier or more difficult to longitudinally traverse. This adjustment of the level of difficulty is, for example, made by Increasing or decreasing drag of the surfboard 100. Real wave effects are also enhanced by dynamic adjustment of both groups of projection angles described above so that the angles can be adjusted while the ride Is operating. The surfing device 10 also has the capability of static adjustment of both groups of projection angles In which case angles of projection are adjusted when the device 10 In not In use.

The surfing device 10 Is designed for essentially non-continuous projection of fluid from nozzles 20 during operation. This fluid projection Is as described In relation to the above referenced present applicant's patent 777355 and relies on sensors and related features described therein. Those sensors and related features are hereby incorporated by reference.

The surface 80 Is modular and constructed of connected modules 232. Modules 232 each have nozzle housings 234 for receipt and housing of nozzles 20. The device 10 Includes an energy projecting structure in the form of structure 236, which In this particular example, is designed for projecting the fluid 40. The structure 236 Includes structural members In the form of structural members 238 which connect to form structure 236.

Each module 232 of this particular example also Includes connecting means, for example, in the form of nuts and bolts or crimps, ties, and clips, as well as other types of festers 240 for mechanical connection, and also fittings 242. The connecting means may also additionally or alternately comprise chemical connections, comprising for example, heat bonding, ultrasonic welding or gluing or a combination of these. Mechanical connections can also, for example, comprise Interlocking portions of connecting modules 232, cables and a supporting substrate providing a receiving cavity or other receiving feature.

The fitting 242 Is designed for connecting nozzles 20 with the fluid projecting structure 236.The fluid projecting structure 236 Includes the energy projecting means which, referring to figure 3 in this particular example comprises a pump 241 which pumps fluid to the nozzles 20. The fitting 242 can, for example, be integrated Into the modules 232 but alternatively is a separate connected component, for example a sealed coupling.

Each module 232 may contain a few as one nozzle 20 and one means for connecting enother module. As Is best shown in figure 2 the surface 80 of the surfing device 10 Is supported on suspended cable or strap like supports 246 that are themselves supported by a frame 248. The modules 232 are designed to readily facilitate assembly and disassembly for maintenance, and In relation to mobile versions of the surfing device 10, transport between different locations. Referring again to figure 3, lines 250 and 260 represent another example of a range of fluid projection angles and represent values of approximately 5 and approximately 25 degrees relative to the aforementioned tangential plane. Referring to figure 4, this range of angles Is typically more suited to continuous fluid projection of surfing device 300. The surfing device 300 includes, In addition to features of the surfing device 10, fluid relief means which in this particular example comprises fluid relief components 350. These components 350 are designed for removing excess fluid from the surface 80. Excess fluid is any fluid that Interacts adversely with surfing 76. The fluid relief components 350 are also designed to modify surfing 76. This modification is in this particular example designed to alter a level of difficulty of the surfing 76. However the fluid relief components are also, more specifically, designed to alter, for example, one or more of at least the following characteristics of the surfing 76: drag; fluid projection angle; and penetration of the projected fluid. The flutd relief components 350 are also adjustable, both statically and dynamically. Static adjustment includes adjustment performed when the surfing device 300 Is temporerlly In- operational. Contrastingly, dynamic adjustment includes adjustment that is performed during surfing 76. The dynamic adjustment of this particular example is automated. Figures 5a - 5b shows this adjustment and the corresponding effects schematically. Extremes of adjustment and the corresponding effects are represented, at the lower extreme by reference numerals 360 and 370, and the upper extreme by reference numerals 380 and 390.

Fluid relief of the surfing device 300 Is also independently adjustable at different positions of the surface 80. This enables fluid relief to be set at different values at different positions. The adjustment Is effected. In this particular example, by varying a restriction to the flow of fluid through the fluid relief components 350. Referring to figure 5b, examples of extremes of this restriction are represented by reference numerals 400 and 410. In relation to the surfing device 300 a reduction or Increase in fluid relief respectively increases or decreases drag associated with su rfing 76. The fluid relief components 350 are also adjusted to simulate forces of an ocean wave and enhance stability by controlling drag.

Adjustment of the fluid relief of the surfing device 300 is also designed to change the angle of projection of fluid. By reducing or increasing fluid relief the fluid projection angle Is respectively reduced or Increased. This change to fluid projection angle is, in this particular example of a surfing device, at a distance from the surface 80. In relation to surfing device 300, reduced fluid relief bends projected fluid toward a more acute angle relative to the surface 80. This bending Is similar to, In relation to an ocean wave, more uplift. It Is currently understood that this similarity is due to a lowering of the person 70 toward the nozzles 20. The fluid relief adjustment described above In relation to surfing device 300 is also designed to maintain energy transfer of the projected fluid while reducing a distance the energy is transferred from the surface 80.

Fluid relief of the surfing device 300 Is designed to relieve fluid within a range from approximately 100% to approximately 5094 of the projected fluid, ft may, for example, comprise at least one or more of the following: suction or a vacuum; gravity; or centrifugal force.

As Is best shown in figure 6, the other surface of the present Invention Is at least partially porous to facilitate drainage and this takes the form In relation to surface 80 of slotted or gauzed PVC 420. The slotted PVC 420 has a fluid relief ratio of porosity relative to the entire surface area If the surface 80 of approximately 0.52 sqm per sqm. Slots 422 of the slotted PVC 420 are formed by two corresponding pairs of oppositely positioned walls 424 and 426 that collectively define rectangular shaped apertures 428. One pair of the oppositely positioned walls 424 are spaced from each other ranging from approximately 3 to approximately 15mm, and the other pair 426 from approximately 15 to approximately 50mm.

Referring to figure 6a, the partially porous surface of the slotted PVC 420 Is designed to deform upon impact of a fallen rider to absorb the rider's energy and enhance ride safety. The walls 424 and 426 of the slotted PVC 420 deform by buckling. They are designed to buckte quite Instantaneously upon Impact to provide a soft feeling for a fallen rider. The slotted PVC 420 is quite thick and therefore although the walls 424 and 426 buckle quite quickly they are capable of absorbing most of the energy generated during a rider's fall. However, energy absorption can also be adjusted by using different materials, material thicknesses, densities, or a combination of one or more of these. The slotted PVC 420 is also applicable to water sport related rides other than those of the detailed description, for example ride 10. The surface, Is designed for a person to surf on either via the projected fluid of, for example, ride 10 or alternatively by at least partially direct contact with the slotted PVC 420 and via fluid projected out of, over or upon the slotted PVC 420. The cables or straps 246 also absorb a fallen rider's impact. Figure 6d shows the cables 246 looping under the surface 80. Referlng to figure 6c, the cables 246 are slack enough, in the event of a rider falling onto the surface 80, to at least partially move away from the rider proximal their point of Impact 427 and absorb some of the Impact. This away movement also results in corresponding movement of the cables or straps 246 on either side of the rider and at least partial lifting of surface 80. This lifting also contributes to impact absorption by lifting part of the weight of surface 80.

The buckling described above also enhances surfing by temporarily reducing fluid relief as the surfer 70 surfs 76 over the slotted PVC 420. In relation to PVC 420 porosity is reduced by buckling of the walls 424 and 426 and corresponding restriction or throttling of the corresponding apertures 428. A reduction in fluid relief increases the volume of fluid on the surface 80 which In turn pushes the surfer 70 away from the surface 80. This away movement is beneficial to the surfer 70 as it increases uplift.

Another advantage of a reduction In fluid relief Is that It reduces the rate of drainage of fluid drained from the surface 8a This reduction In drainage rate reduces energy usage of the ride 10 by reducing the rate of projection of fluid 40 required to enable the surfer 70 to surf over the slotted PVC 420 without making any significant contact with the slotted PVC 420.

Surface 80 of surfing devices 10 and 300 of figures 1 and 4 Is elongate. Surfing devices 10 and 300 are therefore suitable for surfing 76 alone a longitudinal length of the elongate surface 80. However, particularly in relation to surfing device 300, a person can surf 76 within a relatively confined region. Surface 80 of surfing device 300 is therefore not . necessarily required to be elongate. Surfing device 300 is therefore likely to be more suitable, than device 10, for less complex and expensive Installations. Figure 7 best represents projection of fluid 40 in relation to surfing devices 10 and 300 at angles ranging from approximately 45 degrees to approximately 135 degrees relative to a front edge 82 of the elongate surface 80. Figure 8 shows a surfing device 450 having a surfing surface 460 shaped to simulate the shape of an ocean wave. Surfing device 450 may comprise features of either surfing device 10 or 300. Additional adjustable features of surfing devices 10, 300 and 450 include: the rate of projection of fluid 40; the angle of projection of fluid 40 (as described above); and the shape of the surface 80. These features are adjustable in relation to each of these devices either statically or dynamically or both statically and dynamically. They are also independently adjustable relative to other of these adjustable features and also relative to position of the surface 80. This ena les different values to be set at any given time at different positions. The static and dynamic adjustment corresponds to static and dynamic fluid relief adjustment described above in relation to the surfing device 300. It also includes automatic adjustment control corresponding to manual and automatic fluid relief adjustment which is also described above.

Referring to figures 1 · 4 surfing devices 10, 300 and 450 are also designed for static adjustment of the following: position of noules 20; and fluid projection of nozzles 20 Including their fluid projection capacity. This static adjustment corresponds to static fluid relief adjustment described above. The surfing devices 10, 300 and 450 also optionally include manual and automatic adjustment control corresponding to manual and automatic fluid relief adjustment control described above.

Figure 9 shows another example of a surfing device of the present Invention In the form of lurf!ng device 500. Surfing device 500 Includes, in place of surface 80 of surfing devices 10, 300 and 450, a horizontal and flat surface 510. Sur ace 510 is supported on top of or Just beneath a body of fluid In the form of liquid 520, or alternative, up to approximately 300 mm below an upper surface of the body of liquid 520. The surfing device also includes at least one floatation means In the form of floats 530. The floats 530 are connected to the surface 510 and designed for Its support upon the liquid 520. The floats 530 include static adjustment of the present Invention in the form of static adjustment 540. This static adjustment enables adjustment between extreme float positions 550 and 560 of figure 10.

Another example of a surfing device of the present invention Is surfing device 1000 shown in figure 11, This other example comprises at least one energy projecting means In the form of electromagnetic energy projecting plates 1100. It also Includes the support structure 30 of the surfing devices 10, 3∞ and 450 along with all other features of the surfing device 10. Other features of the surfing device 1∞0 that are identical to those of the surfing device 10 are referenced using reference numerals used in relation to the surfing device 10. Arrows 1200 represent electromagnetic energy projected by the plates 1100. Projected electromagnetic energy 1200 Is another example of energy projection of the present Invention that enables a person 70 to surf 76. As explained above In relation to the surfing device 10, In this other example, the person 70 surfs 76 entirely via direct contact with the projected energy 1200 and essentially independently of surface 80. The plates 1100 project electromagnetic energy 1200 from a position which lies essentially In a plane of the surface 80.

With respect to surfing device 1000 the person 70 surfs 76 on a surface of the present invention in the form of surface 1300 which Is created as follows. Referring to figure 12, surfing 76 Involves B planar object in the form of surfboard 1350. The surfboard 1350 has an appearance which closely resembles surfboard 100. However the surfboard 1350 doesn't include the weved underneath surface 110 of surfboard 100. (n place of the waved underneath surface 110 It has at least one electromagnetic energy receiving region in the form of metallic plates 1360. The surfboard 1350 Is designed In relation, for example, to Its shape and materials to best receive the electromagnetic energy 1200. The design of the surfboard 1350 may also be adjusted according to user preferences, for example shape, thickness, weight texture, stiffness. The electromagnetic energy has a concentration ranging from approximately ISOkgf per square meter to approximately 500kgf per square meter. This energy range relates to an active area of the surface 80 which Is that area of the surface 80 which at any given instant is intended for the person 70 to surf 76 over.

Interaction between the electromagnetic energy 1200 and the metallic plates 1360 creates the surface 1300. As in relation to the surfing device 10, the surface 1300 of the surfing device 1000 is positioned above the surface 80. The surfer 70 surfs 76 over the surface 1300 without making any significant contact with the surface 80. The surfer 70 therefore surfs 76, as In relation to surfing device ID, essentially free from any friction that would result from contact with the surface 80.

It will be appreciated that the invention in at least one of its preferred forms has at least the following advantages:

1. Provision of a simulated wave which is adjustable In real time white a person surfs via It; Adjustability of a simulated wave including for example angle and force of energy projection and also in relation to any region of the surfing device or precise position of, or above, a surface of the surfing device over which a person surfs;

Adjustability of a simulated wave to simulate many and varied natural ocean waves to suit all skill levels. Adjustability, Including for example In relation to features of Kern 2 Immediately above, different wave directions and energy levels In relation to any region or precise position as referenced at item 2 immediately above is vast and possibly Infinite. As such, different simulated waves that can be experienced with one or more embodiments of the surfing device are also vast end possible Infinite. These different simulated waves and different simulated wave experiences can also occur In relation to the same surfing device embodiment Adjustment between these different simulated waves and different simulated wave experiences can also occur dynamically while 8 surfer Is surfing the surfing device, and also In real time;

Efficient transfer of energy to a surfing device such as a surf board or boogie board for efficient energy and power consumption. This is provided, for example, in relation to at least one preferred embodiment because energy Is projected from a position which is proximal that of a person surfing on the device at any given instant tn time, in relation to this preferred embodiment, and at least one other, energy transfer Is more efficient than other wave simulation devices providing similarly sized simulated waves. These other wave simulation devices typically comprise either or both projection of fluid onto a surface or production of a stream of fluid. Both impart significant frictional forces onto a surface of the fluid and these frlctlonal forces typically rapidly reduce fluid velocity. Other wave simulation devices therefore typically require significantly more energy In order to overcome these frictional forces. Relief of fluid from a surface of the surfing device above which a surfer surfs. This relief enables adjustment of interference of residual fluid with, either or both, the projected fluid or fluid contacted by a surfer surfing via the surfing device. It can therefore be used to adjust fluid dynamic aspects of the surfing device to in turn adjust ride characteristics of the device such as those described In relation to the aforementioned advantages. This fluid relief can also be provided In relation to any region of the surfing device or precise position of a surface of the surfing device. It can also at least substantially quickly adjust Interference. Constant and generally even fluid relief provides another advantage of preventing fluid building up on a wave like surface of the surfing device. This limits load bearing requirements of the corresponding support structure and facilitates a corresponding reduction In support structure construction requirements. It also facilitates more flexible design limitations in relation to the surfing device. This Increased flexibility leads, for example, to improvements in impact absorption design and reductions In construction costs compared to other wave simulation devices. Further advantages associated with fluid relief relate to safety whereby fluid can be Instantaneously drained from the surface If so required by an operator to ensure the safety of a participant.

6. Impact absorption by: localised deformation of said other surface; movement of looped support ca bles away from the point of Impact; movement of said other surface into a body of fluid; or a combination of one or more of these.

It will be appreciated by persons skilled in the art that numerous variations or modifications may be made to the invention as shown In the specific embodiments without departing from the spirit or scope of the Invention as broadly described. For example, energy projection may, for example, comprise a combination of fluid and electromagnetic energy projection. The proportion of each form of energy may also be designed to provide the most efficient form of energy transfer to a planar object such as surfboard 100. The present embodiments are, therefore, to be considered In all respects as Illustrative and not restrictive.
