DETAILED DESCRIPTION OF THE INVENTION

[0031] As can be seen in FIGS. 1 and 2, embodiments of the water effect play structures 100 described herein can form the centerpiece of a water play feature. In some embodiments, the water effect play structure 100 may be comprised of a plurality of modular water effect play units 10 assembled together. However, it is also contemplated that the play structures 100 described herein can take on any number of different structural configurations and need not be comprised of the water effect play units 10 of the present disclosure.

[0032] An embodiment of a water effect play unit 10 is shown in FIG. 3. The water effect play unit 10 comprises a first support post 11 and a second support post 12. In the illustrated embodiment, each of the first and second support posts 11, 12 are curved. In other embodiments, each of the first and second support posts 11, 12 may take on other configurations. For example, in some embodiments, each of the first and second support posts 11, 12 may be straight or substantially straight. The lower portion 13 of each of the first and second support posts 11, 12 is configured to be mounted to a play surface. For example, in some embodiments, the lower portion 13 of the support posts 11, 12 may be configured to be bolted into a play surface, such as through a peripheral flange. In other embodiments, the lower portion 13 of the support posts 11, 12 may be configured to be anchored into the ground beneath the play surface.

[0033] The play unit 10 may also comprise one or more crossbars 14. As illustrated in FIG. 3, the crossbar 14 may span between the upper portions of the first and second support posts 11, 12. For instance, the crossbar 14 may have a first end that is connected to an upper portion of the first support post 11 and a second end that is connected to an upper portion of the second support post 12. In some embodiments, the crossbar 14 may be rotatably connected to the first and second support posts 11, 12. In the illustrated embodiment, the crossbar 14 is shown as being positioned at the very top of the first and second support posts 11, 12. In other embodiments, however, one or both of the first and second support posts 11, 12 may continue to a higher elevation, from which one or more play features or aesthetic (e.g. themed) features may be mounted.

[0034] In some, non-illustrated embodiments, a play unit 10 may comprise more than one crossbar 14. For instance, in some embodiments, a play unit 10 may comprise multiple crossbars 14 positioned at different locations along the support posts 11, 12, i.e. at different vertical heights. For example, a second crossbar 14 may be positioned vertically below a first crossbar 14. A play unit 10 may also comprise multiple crossbars 14 positioned at substantially the same location along the support posts 11, 12, i.e. at substantially the same vertical height. For example, a second crossbar 14 may be positioned horizontally adjacent to a first crossbar, depending on the width/thickness of the support posts 11, 12.

[0035] The play unit 10 also comprises one or more water tanks 20. As illustrated in FIG. 3, each of the one or more water tanks 20 may be positioned on a crossbar 14. More particularly, in some embodiments, the crossbar 14 may run horizontally through the water tank 20. In some embodiments, the water tank 20 may be rotatably connected to the crossbar 14, such that the crossbar will serve as an axis of rotation. In other embodiments, the crossbar 14, itself, may be configured to rotate about its longitudinal axis. Although the embodiment illustrated in FIG. 3 has a single water tank 20 positioned on crossbar 14, other embodiments of the play unit 10 described herein may contain a plurality of water tanks positioned on a single crossbar.

[0036] The water tank 20 comprises a first end 21 and a second end 22. The first end 21 of the water tank comprises one or more openings 23. The one or more openings 23 may be sized and configured to prevent outside objects from entering the interior of the water tank 20. For example, in the illustrated embodiment, the one or more openings 23 comprise a single slit-like opening. The width of the slit-like opening may be less than 5 inches, alternatively less than 4 inches, alternatively less than 3 inches. In other, non-illustrated embodiments, the one or more openings 23 may have a number of different configurations and sizes. For example, in some embodiments, the one or more openings may comprise an array of small openings, similar to those found in a watering can or a shower head. In some embodiments, the one or more openings 23 may also comprise a screen or mesh structure positioned across the opening, which prevents objects from entering the interior of the water tank 20.

[0037] In some embodiments, the first end 21 of the water tank may also comprise a closure, or cover, for the one or more openings 23. For instance, the embodiment illustrated in FIG. 5 comprises a cover 24. The cover 24 may be attached to the first end 21 of the water tank through a hinge, such that the cover moves between a position in which it covers the one or more openings 23 (see, e.g. the left image in FIG. 5) and a position in which the one or more openings are exposed (see, e.g., the right image in FIG. 5).

[0038] The second end 22 of the water tank may be configured to have a greater weight than the first end 21 of the tank. For example, in some embodiments, the second end 22 of the water tank may comprise one or more solid regions, contain one or more weights, or a combination thereof. The greater weight of the second end 22 biases the water tank 20 into a first position, in which the first end 21 of the tank is positioned above the second end 22 of the tank. In some embodiments, the first end of the tank 21 may be positioned angularly above, as opposed to directly above, the second end of the tank 22. For instance, in the illustrated embodiment, when the tank is empty the first end 21 may be positioned above the second end 22 at an angle between about 50 degrees and about 85 degrees, alternatively between about 55 degrees and about 85 degrees, alternatively between about 55 degrees and about 80 degrees, alternatively between about 60 degrees and about 85 degrees.

[0039] Although the water tank 20 of the illustrated embodiment has a substantially triangular shape, the water tank may take on any of a number of different shapes. For instance, in some embodiments, the shape of the water tank 20 may be configured to fit a desired play theme.

[0040] Embodiments of the play unit 10 also comprise a water transport system 30. The water transport system 30 is configured to transport water from a water supply (such as a municipal water supply) to the water tank 20. In some embodiments, such as the illustrated embodiment, the water transport system 30 may be concealed within other elements of the play unit 10. For instance, the water transport system 30 may comprise piping that runs through at least one, and optionally both, of the first and second support posts 11, 12. In some embodiments, the water transport system 30 may be connected to a water supply through a connection located below the play surface.

[0041] The water transport system 30 may also comprise piping that runs at least partially, and optionally entirely, through the crossbar 14. For instance, the crossbar 14 may comprise one or more nozzles or manifolds through which water may be delivered from the water transport system 30 directly to the interior of the water tank 20. In some embodiments, therefore, the flow of water into the water tank 20 during filling may be completely concealed. In those embodiments where the play unit 10 comprises a plurality of crossbars 14, the water transport system 30 may be configured to supply water through each of the plurality of crossbars 14.

[0042] Embodiments of the play unit 10 may also comprise one or more deflectors 40. For instance, a deflector 40 may be positioned below the water tank 20. In some embodiments, the deflector 40 may be supported by a lower crossbar 15. In the illustrated embodiment, for example, a lower crossbar 15 spans between the first and second support posts 11, 12 below the crossbar 14 that supports the water tank 20. The lower crossbar 15 may have a first end that is connected to an upper portion of the first support post 11 and a second end that is connected to an upper portion of the second support post 12. In some embodiments, the lower crossbar 15 may be rotatably connected to the first and second support posts 11, 12, the deflector 40 may be rotatably connected to the lower crossbar 15, or a combination thereof. In other, nonillustrated embodiments, the deflector 40 may not be mounted on a crossbar 15 but rather may itself be connected to the first and second support posts 11, 12.

[0043] In some embodiments, the water supply system 30 may also be configured to supply water to the lower crossbar 15. For instance, in some embodiments, the lower crossbar 15 may comprise one or more openings or nozzles through which water may flow. For example, in addition to supporting a deflector 40, the lower crossbar 15 may provide any of a variety of water effects, such as a rain curtain. Similarly, in those embodiments where the deflector 40 is not mounted on a crossbar 15 but rather itself connected to the first and second support posts 11, 12, the water supply system may be configured to supply water to the deflector itself 40 to provide any of a variety of additional water effects, such as a rain curtain.

[0044] The deflector 40 may be positioned so that water flowing out of the water tank 20 contacts a surface 41 of the deflector 40 on its way toward the play surface. In some embodiments, for example, the deflector 40 may be angled so as to direct the water flowing out of the water tank 20 in a particular direction. For instance, in the embodiment illustrated in FIG. 3, the deflector 40 is configured to direct the water toward the front of the play unit 10. In other embodiments, the deflector 40 may be configured to direct the water toward the rear of the play unit 10 (e.g. its position on the play unit may be reversed). The angle of the deflector 40 (and hence the angle at which the water flows off of the deflector) may be varied and selected to provide a particular splash effect.

[0045] The surface 41 of the deflector 40 may also have one or more features configured to manipulate the water so as to cause the water to flow off of the deflector 40 in a particular manner, thereby providing a unique splash effect. For instance, the deflector 40 may comprise a concave surface 41, as shown in the illustrated embodiment, or a surface comprising concave elements. In other embodiments, the deflector 40 may comprise a convex surface 41 or a surface comprising convex elements. In other embodiments, the surface 41 of the deflector 40 may comprise one or more upward protrusions, e.g., teeth or bumps, around which the water flows (such teeth may also be provided in combination with concave or convex surface features).

[0046] In some embodiments, the flow of water onto the deflector 40 may cause the deflector to rotate to provide particular splash effects. For instance, in some embodiments, the deflector may comprise one or more wheels over which water flows. In other embodiments, the deflector 40 may comprise one or more orifices that, when filled with water, cause the deflector to tilt about the crossbar 15 (or the crossbar to rotate about the support posts 11, 12 causing the deflector to tilt) so as to provide a second, delayed splash effect. The variety of splash effects that can be achieved by the incorporation of different deflectors 40 is almost limitless.

[0047] In some embodiments, the play unit 10 may be configured to include one or more additional water spray effects. For instance, in the illustrated embodiment, each of the first and second support posts 11, 12 comprises a water spray nozzle 16 extending toward the front of the play unit. The type and position of these additional water spray effects may be varied to provide a desired play experience.

[0048] In some embodiments, the play unit 10 may be configured so that the types of water effects, as well as the positions of the various water effects, may be interchangeable. For example, in the embodiment illustrated in FIG. 4, the first and second support posts 11, 12 may each comprise a standardized joint 17, such as a stab fitting, to which a variety of water effect elements may be attached. As shown in the illustrated embodiment, crossbars 14, 15 may comprise feed through joints 18 and an intermediate connecting element—in the illustrated embodiment an element comprising an additional water spray nozzle 16, although a variety of connecting elements may be used in its place—may span between and separate the two feed through joints. At the very top of the support posts 11, 12 may be positioned a joint cap 19. In some embodiments, the joint cap 19 may also comprise a water nozzle or other water spray effect. Using this arrangement, support posts 11, 12, once installed may be converted into a variety of different play units 10 simply by interchanging the water spray elements attached to the standardized joint. This arrangement may also simplify repair of the play unit 10, since a non-functioning element may easily be removed and replaced.

[0049] The play unit 10 may be configured so that the water tank 20 is in a first position while it fills with water until, upon reaching an activating volume of water inside the tank, the tank rotates or flips into a second position, dumping the water contained therein downward through the one or more openings 23. In some embodiments, a relatively large movement of the water tank 20 between the first and second positions may be desirable, as it will be eye-catching to children and increase the enjoyment of the play unit 10. In other words, it may be desirable that the water tank 20 not merely move from a position in which the first end 21 is located slightly above horizontal to a position in which the first end 21 is located slightly below horizontal, but rather that the tank rotate across a relatively large arc when an activating volume is reached. For instance, in some embodiments, upon reaching an activating volume the water tank 20 will rotate at least 35 degrees, alternatively at least 45 degrees, alternatively at least 55 degrees.

[0050] Depending on the direction in which the water tank 20 is positioned, the water tank may be configured to flip toward the front of the play unit 10 or toward the rear of the play unit. As previously described, a deflector 40 may also be used to direct water toward the front of the play unit 10 or toward the rear of the play unit. Therefore, different effects can be provided by altering the directions of the water tanks 20 and deflectors 40 (e.g. a water tank can flip toward the rear of the play unit but the water can be directed toward the front of the play unit by a deflector; a water tank can flip toward the front of the play unit and the water can be directed toward the front of the play unit by a deflector; etc.).

[0051] In some embodiments, the water tank 20 may rotate about the crossbar 14. In other embodiments, the tank 20 may be fixed to the crossbar 14 and the crossbar may rotate about the support posts 11, 12. In yet other embodiments, rotation of the water tank 20 between the first and second positions may occur through a combination of these processes.

[0052] Rotation of an embodiment of a water tank 20 between a first position and a second position is illustrated for example in FIG. 5. In the illustrated embodiment, cover 24 is caused by gravity to move between a closed position (when the water tank 20 is in a first position) and an open position (when the water tank is in a second position). The flow of water through the one or more openings 23 may also cause the cover 24 to open. In some embodiments, the cover 24 may also be used to direct the flow of water from the one or more openings 23 in a particular direction.

[0053] Once the contents of the water tank 20 have been emptied, the weight of the second end 22 of the tank will cause the tank to rotate, or flip, back into the first position, whereupon it will begin to fill again.

[0054] In some embodiments, the play unit 10 may be modular. For instance, in some embodiments, a number of play units 10 utilizing the same basic sets of components may be linked together, such that certain components are shared by adjacent play units 10. In some embodiments, for example, a play structure 100 may comprise a first play unit 10 and a second play unit 110 linked together. The second play unit 110 may comprise a third support post 111 and a second crossbar 114. The third support post 113 may be substantially identical to the first and second support posts 11, 12. Like the first and second support posts 11, 12, the third support post 111 may have a lower portion 13 configured to be mounted to the play surface. The second crossbar 114 may be substantially identical to crossbar 14. The second crossbar 114 may span between the second support post 12 and the third support post 113. For instance, the second crossbar 114 may have a first end connected to an upper portion of the second support post 12 and a second end connected to an upper portion of the third support post 113. The second play unit 110 may also comprise one or more water tanks 120 positioned on and supported by the second crossbar 114, as well as a water transport system 130 configured to transport water into the one or more water tanks.

[0055] By providing modular play units 10 that may be assembled together as described above, a number of play units 10, 110 may be linked together to form a play structure 100. Each of the support posts 11, 12 may be configured to support a first crossbar 14 on one side of the support post and a second crossbar 114 on the opposite side of the support post. Accordingly, play structures 100 assembled using embodiments of the modular play units 10 minimize the number of support posts 11, 12 required. Additionally, the same set of components may be used to prepare play structures 100 of varying sizes and shapes, minimizing the manufacturing costs while allowing for the construction and installation of customized play structures.

[0056] For instance, in some embodiments, a third play unit 210 may be linked to the second play unit 110 in the manner described above. The third play unit 210 may comprise an additional support post 211, an additional crossbar 214, one or more additional water tanks 220, and a water transport system 230 configured to fill the one or more additional water tanks. Similarly, a fourth play unit 310 may be linked to the third play unit 210 in the manner described above. The fourth play unit 310 may comprise an additional support post 311, an additional crossbar 314, one or more additional water tanks 320, and a water transport system 330 configured to fill the one or more additional water tanks. Although not illustrated, additional (e.g. fifth, sixth, seventh, etc.) play units may also be linked in order to form larger play structures 100.

[0057] In some embodiments, one or more of the linked play units 10, 110, etc. may comprise deflectors 40, 140, 240, 340. In some embodiments, for example, each deflector 40, 140, 240, 340, etc. may be mounted on a respective lower crossbar 15, 115, 215, 315, etc. as described herein.

[0058] To facilitate the construction of play structures 100 through the modular connection of a plurality of play units 10, it is important the play units 10 and the components thereof are easy to install and adaptable to at least a small degree of misalignment. For instance, the connection between a crossbar 14 and the support posts 11, 12, etc. may be configured to be water tight even where one or more of crossbars 14, 114 may not connect to a support post 11, 12, etc. in perfect alignment. For instance, when multiple play units 10 are connected modularly, there may be some differences in the exact locations at which each crossbar 14, 114, etc. intersects a support post 11, 12, etc. and/or in the exact angles at which each crossbar intersects a support post. Accordingly, the support posts 11, 12, etc. may comprise a crossbar connection element that is configured to accept and secure a crossbar 14, 114, etc. to form a water-tight connection despite a degree of imprecision as to the exact location (vertical and/or horizontal) at which the crossbar is connected and/or the exact angle of the crossbar at the point of connection.

[0059] The water transport systems 30, 130, etc. of the assembled play units 10, 110, etc. may be linked together so that only one connection with a water supply is necessary to supply water to each of the water tanks 20, 120, etc. In some embodiments, each of the water transport systems 30, 130, etc. may be linked such that water flows to each play unit individually, e.g. through an underground linkage. In other embodiments, each of the water transport systems 30, 130, etc. may be linked within the play structure 100 itself, such that a single flow of water extends to the water tanks 20, 120, etc. of more than one play unit 10, 110, etc.

[0060] A play structure 100 may be prepared by linking a plurality of play units 10, 110, etc. in series. For example, in some embodiments, the play structure 100 may comprise a row of play units 10, 110, etc, linked side-by-side. The play units 10, 110, etc. may be arranged to form a straight line, a zig-zag, a circular arc, etc. For instance, an embodiment of a play structure 100 comprising four play units 10, 110, 210, 310 arranged in a circular arc is shown in FIG. 6.

[0061] A play structure 100 may also be prepared by linking a plurality of play units 10, 110, etc. in a closed circuit. In some embodiments, the closed circuit of play units 10, 110, etc. may form a polygon. For instance, three play units 10, 110, 210 may be assembled so that each play unit 10, 110, 210 is connected to two adjacent units to form a triangle. Or, as shown in FIG. 7, four play units 10, 110, 210, 310 may be assembled so that each lay unit is connected to two adjacent units to form a square. In other embodiments, the closed circuit may form a circle (such as where the crossbars 14, 114, etc. of the various play units 10, 110, etc. are curved). Note that where the play units 10, 110, etc. are assembled in a closed circuit, the number of support posts 11, 12, 111, etc. required may be further minimized. For instance, the play structure 100 shown in FIG. 7 contains only four support posts 11, 12, 111, 211.

[0062] Embodiments of the play structure 100 described herein may provide a number of unique play opportunities. For example, in some embodiments, one or more of the plurality of water tanks 20, 120, etc. may be configured to release the water contained therein, i.e. tip, at different times. In some embodiments, the plurality of water tanks 20, 120, etc. may be configured to tip at random or in a substantially random order. This may provide a unique play experience, as children will not know which water tank 20, 120, etc. is about to release its water, leading children to move between the various play units 10, 110, etc. In addition to keeping a child's attention for a longer duration, embodiments of the play structure 100 described herein may therefore also lead to a more active play experience.

[0063] Another additional benefit is that, in some embodiments, there may be a near constant movement of tanks 20, 120, etc., which may be visually eye-catching and draw children to the structure 100. For instance, in some embodiments, one or more of the plurality of water tanks may tip within every 60 second interval, alternatively within every 45 second interval, alternatively within every 30 second interval, alternatively within every 20 second interval, alternatively within every 15 second interval.

[0064] Embodiments of the play structures 100 described herein may be configured so that one or more of a plurality of water tanks 20, 120, etc. release the water contained therein, i.e. tip, at different times in a number of different ways.

[0065] In some embodiments, the water tanks 20, 120, etc. may be configured to fill at different rates, i.e., the water transport system 30, 130, etc. may be configured to supply water to the water tanks 20, 120, etc. at different rates. For instance, the water supply systems 30, 130, etc. for the different play units 10, 110, etc. may comprise piping having different diameters, the water supply systems for the different play units may comprise different nozzles or manifolds, the water supply systems may be configured to pump the water to the different play units at different pressures, the water supply systems for the different play units may comprise one or more obstructions or flow paths of differing lengths, or any combination of the above. In some embodiments, a pump may be configured and programmed to provide water to the plurality of water tanks 20, 120, etc. at random or substantially random rates.

[0066] In some embodiments, the water tanks 20, 120, etc. may have different activation volumes. For example, the water tanks 20, 120, etc. for the different play units 10, 110, etc. may have different interior volumes, the water tanks for the different play units may have different geometries, the water tanks for the different play units may have different weights incorporated into the second end, or any combination thereof. In some embodiments, both the water transport system 30, 130, etc. may be configured to supply water to the water tanks 20, 120, etc. for the different play units 10, 110, etc. at different rates and the water tanks for the different play units may have different activation volumes.

[0067] Embodiments of the play structures 100 described herein may also be configured so that one or more of the plurality of water tanks 20, 120, etc. release the water contained therein so as to provide splash effects in a variety of different directions. For instance, where the play structure 100 comprises a plurality of play units 10, 110, etc. in series, at least one of the plurality of water tanks 20, 120, etc. may be configured to provide a splash effect to the front of the structure 100 and at least one of the plurality of water tanks may be configured to provide a splash effect to the rear of the structure. In some embodiments, for instance, adjacent play units 10, 110, etc. may provide splash effects in alternating directions.

[0068] Using embodiments of the present disclosure, providing splash effects in multiple directions may be achieved in a number of manners. For example, the water tanks 20, 120, etc. may be positioned so as to tip in different directions, e.g. water tank 120 may be positioned on the crossbar 114 or the crossbar 114 may be connected to the support posts 12, 111 so that the water tank 120 faces the opposite direction from water tank 20. Alternatively, one or more of the deflectors 40, 140, etc. may be positioned so as to cause a splash effect to occur in a different direction. For example, deflector 40 may be positioned to cause a splash effect toward the front of a play structure 100 and adjacent deflector 140 may be positioned to cause a splash effect toward the rear of a play structure. In other embodiments, both the water tanks 20, 120, etc. may be positioned to tip in different directions and deflectors 40, 140, etc. may be positioned to cause the water to flow in different directions.

[0069] In the embodiment illustrated in FIG. 7, for example, the play structure 100 is configured so that each of the splash effects occurs to the exterior of the polygonal structure. This may have the additional benefit of creating a dry zone at the center of the structure 100. Children and adults may enjoy congregating in the dry zone and enjoying the entertainment and cooling effects of the flowing water without getting wet. In the illustrated embodiment, each of the water tanks 20, 120, 220, 320 is configured to tip inward toward the center of the play structure 100, but the released water is manipulated by the deflectors 40, 140, 240, 340 so as to flow toward the exterior of the structure. This may provide an enjoyable visual effect for children and adults located in the central dry zone. Namely, when the deflectors 40, 140 etc. are transparent or translucent, it will appear that water being released from the tanks 20, 120, etc. is falling directly onto those located in the dry zone. Other configurations are also contemplated however. In the illustrated embodiment, each of the additional water spray effects 16 is also positioned so as to spray toward the exterior of the structure. In other, non-illustrated embodiments, a plurality of the splash effects may be configured to occur toward the interior of a polygonal structure 100, thereby causing a central soak zone.

[0070] Embodiments of the play structures 100 described herein may also be configured so that one or more of the play units 10, 110, etc. provide different splash effects. For instance, the deflectors 40, 140, etc. associated with the plurality of water tanks 20, 120, etc. may differ from one another. By providing a play structure 100 with different types of deflectors 40, 140, one can provide a variety of unique splash play opportunities within a single structure 100. It may also provide a preserved element of surprise, as children may forget which play unit 10, 110 provides which unique splash effect especially when the play units 10, 110, etc. are configured in a closed circuit.

[0071] In some embodiments, the support posts 11, 12 for each play unit 10 may also be configured so that they can be mounted in a variety of configurations, providing an additional degree of flexibility for the design of unique and customized play structures 100. For instance, the support posts 11, 12 of the illustrated embodiments may be mounted in at least four different ways, as illustrated in FIG. 8: (i) the support posts may be mounted so as to curve outward toward the sides of the play unit 10, as illustrated in FIG. 8A; (ii) the support posts may be mounted so as to curve inward away from the sides of the play unit, as illustrated in FIG. 8B; (iii) the support posts may be mounted so as to curve toward the front of the play unit, as illustrated in FIG. 8C; and/or (iv) the support posts may be mounted so as to curve toward the rear of the play unit, as illustrated in FIG. 8D. This flexibility allows for the construction of play structures 100 having a variety of unique shapes and designs.

[0072] In some embodiments, each of water tanks 20, 120, etc. may be configured to hold between about 5 and about 30 gallons of water, alternatively between about 5 and about 20 gallons, alternatively between about 8 and about 18 gallons, alternatively between about 10 and about 15 gallons. In some embodiments, the different water tanks 20, 120, etc. in a play structure 100 may hold different volumes of water, such that the splash effects from different play units 10, 110, etc. have varying levels of magnitude.

[0073] It can be seen that the described embodiments provide unique and novel play units 10 and structures 100 that have a number of advantages over those in the art. While there is shown and described herein certain specific structures embodying the invention, it will be manifest to those skilled in the art that various modifications and rearrangements of the parts may be made without departing from the spirit and scope of the underlying inventive concept and that the same is not limited to the particular forms herein shown and described except insofar as indicated by the scope of the appended claims.
