bolts are optionally used to secure the first end 20 of the conduit 19 to the concrete footing 24 . it will be understood by those skilled in this art that other appropriate devices and / or members can be used to secure the first central pedestal 4 to a collection basin surface . if no additional polygonal decks are desired , the second end 20 of the first central pedestal 4 may be connected in any suitable manner to a cap 7 , which is designed to prevent water from flowing out of the second end 21 of the first central pedestal 4 . alternatively , the first central pedestal 4 can be manufactured with a closed second end 21 . as shown in fig1 a - 1 c , the first water supply leg 8 and second water supply leg 10 may partially support the first polygonal deck 12 and may transmit pressurized water to water play elements 17 generally disposed upon railings 14 or on the first and second water supply legs 8 , 10 , or both . in one embodiment , the first and second water supply legs 8 , 10 are pipe - like and l - shaped . as one ordinarily skilled in the art can appreciate , other manners or shapes of pipe , tubing , or other functionally shaped water - carrying conduit of sufficient strength and size to transmit pressurized fluid are within the spirit and scope of the present invention . moreover , the present invention is not limited to a particular type of water play element 17 . for example , a faucet 36 and tipping buckets 34 are shown in fig1 a , but other water play elements 17 may be substituted for these elements or these elements may be moved to different positions on the structure . blind flanges 24 b may be used to cap the first water supply leg 8 and second water supply leg 10 when those water transfer positions are not in use . additional conduit 24 a may be attached to flanges formed in first water supply leg 8 and second water supply leg 10 as may be necessary . such conduit 24 a can be used to supply pressurized water to additional water play structures or to other types of water play elements , play pods , etc . alternatively , the conduit 24 a could be simply used as a water spout . as previously noted , water may be emitted from various water play elements 17 positioned about the water play structure 2 . the emitted water is collected in the pool 3 . the pool 3 may vary from a substantially zero depth to a depth of several feet depending on the needs of the operator . as shown in fig2 in one embodiment , the pool 3 is further comprised of a drain 25 , which allows the water to circulate back to the water supply . the drain 25 may communicate with a central water supply or the fluid exiting the drain may be held in a storage facility . in either case , a pump 26 , which can be positioned on the pool floor 18 , or on a skid which is anchored to the water play structure 2 , or remote thereto , may be used to move fresh and / or re - circulated water to the water play structure 2 . as one skilled in the art can appreciate , the size and power of the pump 26 will be dictated by the volume of water to be moved , the distance that the water must travel , the pressure required to operate the water play elements 17 on various levels of the modular water play structure 2 , etc . an additional aspect of the present invention is to provide the ability to quickly and easily modify and interchange , if necessary , interactive play modules 27 ( see , e . g ., fig3 a ) to accommodate operator needs . in one embodiment , the interactive play module 27 is comprised of at least one railing 14 ( see fig3 b ) interconnected to a frame 28 , which houses an interactive play apparatus 16 and which may be secured to the first polygonal deck 12 via an appropriate attachment means 30 . such an attachment means 30 may be a flange , bracket , bolts , weld , epoxy glue , rivets , or other similar device . this modular configuration provides a myriad of combinations for the operator and facilitates quick replacement of the entire interactive play module 27 , if desired . see fig3 a and 3b . this ease of interchangeability also facilitates servicing of the play structure 2 and the play elements 17 , and simplifies design and manufacture of both the interactive play modules 27 and overall play structure 2 . as shown in fig1 a , 3a , and 3 b , the railing 14 can be swapped with various water play elements 17 ( e . g ., sprinkler 32 , series of swiveling buckets 34 coupled to a faucet 36 , etc .). in one embodiment , the railing 14 has a first end 38 and a second end 40 , each of which is preferably flanged so that the railing 14 can be easily removed for servicing or replacement . the railing 14 can be made out of metal , metal alloy , or other material having similar strength and durability characteristics , or a combination thereof . the railing frame 28 can house spindles 42 ( see fig3 b ), the interactive play apparatus 16 ( see fig3 a ), or both . as shown in fig1 a , different interactive play apparatuses 16 , such as a tic - tac - toe module 44 , a gear - oriented module 46 , a propeller - mounted module 47 , a spinning ball module 48 , a maze - oriented module 49 , or a slide module 50 ( not shown ), can be easily interchanged within an interactive play module 27 , depending on the needs of the operator . if the operator so desires , the entire interactive play module 27 can also be removed and replaced by simply disconnecting the attachment means 30 and the first end 38 and , if necessary , the second end 40 of the railing 14 , and replacing the interactive play module 27 with another pre - assembled interactive play module 27 . the aforementioned interactive play apparatuses 16 and water play elements 17 are intended to be for illustrative purposes only . as one ordinarily skilled in the art can appreciate , other interactive play apparatuses 16 and / or water play elements 17 may be used alone , or in combination , without departing from the spirit and scope of the present invention . another aspect of the present invention is to provide a modular water play structure 2 which can easily adapt to accommodate additional play participants . depending on the projected number of play participants , additional polygonal decks can easily be added to the structure , building off of the first central pedestal 4 . this is accomplished by adding additional decks and corresponding water supply legs to the central pedestal 4 . as shown in fig4 a and 4b , in one embodiment , up to a four level water play structure 2 can be achieved by tiering polygonal decks in a staircase manner . the decks may be located at different heights on the central pedestal by adding central pedestal sections . each additional polygonal deck may be supported , in part , by the polygonal deck that precedes it . for instance , in order to achieve a second level 51 , a second central pedestal 52 is connected to the first central pedestal 4 that is anchored near , to , or beneath the pool floor 18 . see fig5 a - 5 c . a third water supply leg 54 may be connected to the second central pedestal 52 so that water can be carried to water play elements 17 positioned on railings 14 on the second level 51 of the water play structure 2 . in addition , the third water supply leg 54 may partially support a second polygonal deck 58 . the second polygonal deck 58 may also be partially supported by the second water supply leg 10 via a first support member 60 . in one embodiment , additional stairs 17 a are positioned from the first polygonal deck 12 to an edge of the second polygonal deck 58 . if a third level 62 to the play structure is desired , as shown in fig6 a - 6 d , a third central pedestal 64 may be connected to the second central pedestal 52 . similarly , a fourth water supply leg 66 may be connected to the third central pedestal 64 in order to carry water to further water play elements 17 on the third level 62 and to partially support a third polygonal deck 68 . the third polygonal deck 68 may be supported in a similar fashion , as described above , by a second support member 70 that spans between the second polygonal deck 58 and the third polygonal deck 68 . stairs 17 a may also connect the second polygonal deck 58 and third polygonal deck 68 so that play participants can freely move between the second and third levels 51 , 62 . turning now to fig3 and 7a - 7 g , if the operator requires a fourth level 72 , a fourth central pedestal 74 may be connected to the third central pedestal 64 . in one embodiment , the fourth central pedestal 74 is further comprised of means 22 ( e ., a flange or bracket ) for connecting a fourth polygonal deck 76 to the fourth central pedestal 74 . in this embodiment , no water supply leg is used to support the fourth polygonal deck 76 . rather , the fourth polygonal deck 76 is supported by third and fourth support members 78 , 80 , respectively . however , the first water supply leg 8 and fourth water supply leg 66 are used to supply pressurized water to water play elements 17 which may be installed on the fourth polygonal deck 76 . the third support member 78 spans between the fourth water supply leg 66 and the fourth polygonal deck 76 ; the fourth support member 80 spans between the first water supply leg 8 and the fourth polygonal deck 76 . again , stairs 17 a may be added to interconnect the third polygonal deck 68 with the fourth polygonal deck 76 . in order to provide further stability to the modular water play structure , as shown in fig8 a and 8b , optional , adjustable support columns 82 can be positioned beneath the first , second , third , or fourth water supply legs 8 , 10 , 54 , and 66 , respectively . each adjustable support column 82 can be extended to accommodate any height differences between the water supply legs and the pool floor 18 . in one preferred embodiment , each adjustable column 82 is comprised of a stationary post 84 in telescopic relationship with a sleeve 86 . the stationary post 84 may be removably or fixedly connected to the pool floor 18 by bolts , glue , or other securement methods known in the art . alternatively , the stationary post 84 may simply rest upon the pool floor 18 . even if the stationary post 84 is not secured to the pool floor 18 or , for that matter , if it rests above the pool floor 18 , it will have the effect in many instances of supporting deck structure , especially if the deck structure begins to oscillate as a result of play participant activity . once the telescoping sleeve 86 is adjusted to a proper height to either partially or fully support a polygonal deck , the telescoping sleeve 86 may be fixedly or removably connected to either a water supply leg and / or the underside of a polygonal deck via an attachment device , which may include a flange , bracket , or other coupling mechanism known in the art . in order to ensure that the telescoping sleeve 86 stays in position , in one embodiment , the telescoping sleeve 86 is further comprised of a plurality of apertures 88 to accept bolts 90 , which are temporarily or permanently tightened against the stationary post 84 . see fig8 b . as one ordinarily skilled in the art can appreciate , other methods of adjusting and securing the adjustable support column 82 are within the spirit and scope of the present invention . moreover , the adjustable support column 82 , as well as the modular water play structure 2 generally , can be made out of a rust - resistant , durable metal , metal alloy , or other material having similar strength and non - corrosiveness characteristics , or a combination thereof . if four levels are insufficient to accommodate the number of play participants , additional modular water play structures 2 may be added to the overall system . in such a preferred embodiment , the first central pedestal 4 may be modified to include a second supply line connection 92 ( not shown , but identical to water supply line connection 6 in fig2 ), which connects the first central pedestal 4 to an identical first central pedestal 4 that is similarly anchored at , near , or beneath a pool floor 18 at a sufficient distance from the first modular water play structure 2 . the second modular play structure 2 can be built to the desired number of levels in the manner described above . additional modular water play structures 2 can be added in like fashion , if desired . the first , second , third , and fourth central pedestals 4 , 52 , 64 , 74 , respectively , and first , second , third and fourth water supply legs 8 , 10 , 54 , and 66 , respectively , are preferably made out of a rust - resistant , durable metal , such as stainless steel or other metals having similar strength and durability characteristics , and are to be of sufficient size and strength to safely support the modular water play structure 2 and play participants while also supplying pressurized water to the various interconnected water play elements 17 . similarly , all manners or shapes of pipe , tubing , or other functionally shaped water - carrying channel of sufficient strength may be used for the above - described central pedestals and water supply legs and still be within the spirit and scope of the invention . as one ordinarily skilled in the art can appreciate , the first , second , third , and fourth support members 60 , 70 , 78 , and 80 , respectively , can take various forms and be constructed of various materials and still be within the spirit and scope of the present invention . for example , railing / spindle configurations , as shown in fig3 and 5a or horizontally - positioned i - beams ( not shown ) can be used . in addition , the previously described interconnections between the central pedestals , water supply legs , and railings can take various forms . for instance , coupling assemblies , threaded conduit , or other connections that are designed to accommodate pressurized fluids are well within the scope of the present invention . moreover , gaskets 94 ( shown in fig7 b ) may optionally be used between some or all points of connection between water transferring conduit . the first , second , third , and fourth polygonal decks 12 , 58 , 68 , and 76 , respectively , can also vary in shape , thickness , and size . preferably , each polygonal deck has at least three sides and is made from fiberglass or other material providing a non - slip , non - corrosive , non - degrading surface . as shown in fig7 c , in one embodiment , each polygonal deck is hexagonal . various means for connecting each polygonal deck to each respective central pedestal or water supply leg can be used , such as flanged connections or brackets . any such connection method is deemed within the skill of those working in this art . in order to operate the water play elements 17 on the various levels of the modular water play structure 2 , play participants turn valves 96 ( as shown in fig1 b ), which are strategically placed along the railings 14 or other areas of the system . various valves 96 , such as butterfly , gate , etc ., may be used alone , or in combination and still be within the scope of the present invention . water flow may also be increased or decreased to a particular section of the modular water play structure 2 by adjusting the respective valve 96 . as noted above , the pool 3 can vary in depth , size and configuration . as one ordinarily skilled in the art can appreciate , filtration and water structures are to be incorporated per local building code or other requirements . while an effort has been made to describe some alternatives to the preferred embodiment , other alternatives will readily come to mind to those skilled in the art . therefore , it should be understood that the invention may be embodied in other specific forms without departing from the spirit or central characteristics thereof . the present examples and embodiments , therefore , are to be considered in all respects as illustrative and not restrictive , and the invention is not intended to be limited to the details given herein .
