Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of patent application Ser. No. 10/265,821, filed Oct. 7, 2002, which is a continuation of patent application Ser. No. 09/879,852, filed Jun. 11, 2001, which are hereby incorporated by reference.[0001]

BACKGROUND OF THE INVENTION

1. The Field of the Invention

The present invention relates generally to floating recreational devices, and more particularly, but not necessarily entirely, to a movable, floating modular playground configured to accommodate various playground equipment for kids of all ages.

2. The Relevant Technology

The prior art discloses a number of water trampolines. Water trampolines provide a leisure time activity for kids of all ages in a body of water. The combination of a trampoline and an inflatable vessel allows users to enjoy the bouncing and acrobatic activities performed on a trampoline with the benefits of playing in the water. However, the disclosed trampolines are limited to only one recreational device, the trampoline.

U.S. Pat. No. 6,223,673 granted to Mears et al. discloses a floatable park that includes a trampoline and a first inflatable object attached to the trampoline. Mears discloses attaching another recreational device to the trampoline, such as a giant inflatable pillow, an inflatable log or a slide. However, the park needs to be inflated with air and is only held together with straps.

The prior art also discloses a number of floating docks and decks. For example, U.S. Pat. No. 6,073,572 granted to Gruhn et al. discloses a floating dock. Gruhn discloses individual modular floating sections that can be connected together to form a floating structure. However, the prior art docks and decks are limited to a floating deck structure without additional attachments.

U.S. Pat. No. 5,823,132 granted to Donovan discloses a floating deck structure. Donovan discloses a structural deck that floats on a rigid, buoyant material filled watertight float. The deck can be configured to accommodate a variety of accessories and furnishings for various recreational activities. However, the invention is not modular in design and limited to a deck structure.

The prior art fails to disclose a rigid floating playground module which can be interconnected to other playgrounds. The disclosed playgrounds achieve their buoyancy with an inflatable member, which can be punctured and require patching or replacement.

The prior art is thus characterized by several disadvantages that are addressed by the present invention. The present invention minimizes, and in some aspects eliminates, the above-mentioned failures, and other problems, by utilizing the methods and structural features described herein.

BRIEF SUMMARY OF THE INVENTION

Applicant has discovered that floating playgrounds are more versatile and provide more recreation if the playground is movable and modular. The modular design allows different modules with different recreational implements to be connected together, and later disconnected and interchanged for other modules. Applicant has thus conceived of a floating playground that supports a variety of recreational implements, is movable and floats. A preferred design concept of the floating playground comprises two modules attached together. Each module rests on a floating vessel and has a frame encircling the perimeter of the vessel. Preferably vertical posts are attached to the frame and support various recreational implements. [0046]
Referring now to FIG. 1, there is shown a perspective view of two [0047] modules 11 attached together to form the floating playground generally at 10. A module 11 can be any size, but preferably is no more than eight and one half feet wide, such that the module 11 can fit on a trailer and be transported without a permit. Preferably, the module 11 is supported by a floating vessel 12 that provides buoyancy to the module 11. The vessels 12 are preferably rectangular in shape, made from rotationally molded plastic and filled with foam, or expanded polystyrene, for buoyancy. The expanded polystyrene preferably has a density of 1 lb/ft³. The foam prevents the vessels 12 from filling with water in the event that the plastic shell of the vessel 12 is breached. Referring now to FIG. 1A, there is shown a breakaway, perspective view of one of the vessels 12 shown in FIG. 1. A ledge 14 is molded into the vessel 12 and preferably circumscribes the entire upper perimeter of the vessel 12. The ledge 14 defines an upper portion 16 and a lower portion 18 of the vessel 12. Four pockets 20, or slots, are molded in the upper portion 16 of the vessel 12. The pockets 20 are preferably located just above the ledge 14 with two pockets 20 residing on each longitudinal edge of the vessel 12 near the ends.
Referring again to FIG. 1, the [0048] ledge 14 receives a frame 22 that is preferably made of metal. The frame could also be made of any suitable material to those skilled in the art. The frame 22 is preferably a hollow member, with a rectangular cross-section. The frame 22 circumscribes one vessel 12. Referring now to FIG. 1B, there is shown a partial, cross-sectional view of one of the modules 11 shown in FIG. 1. After the frame 22 is placed on the ledge 14, an attachment means 24, preferably an angle iron made of metal, with a first portion 24 a and a second portion 24 b is slid into each of the four pockets 20. The attachment means 24 could be any other suitable device, made of a suitable material to those skilled in the art, depending on the type of material used to make the frame 22. The attachment means 24 is positioned such that the first portion 24 a slides into the pocket 20 and the second portion 24 b rests flush against the frame 22. The second portion 24 b of the attachment means 24 is then attached to the frame 22, preferably by welding. The attachment of the frame 22 to the four attachment means 24 securely attaches the frame 22 to the vessel 12. Referring again to FIG. 1, a preferably vertical post 28 attaches to the frame 22, preferably by welding. The posts 28 are preferably made of metal, but can be made of any other suitable material used to make the frame 22. The posts 28 can be placed anywhere on the frame 22 in a manner to support any type of recreational implement (not shown).
Referring now to FIG. 1C, there is shown a bottom view of one of the [0049] vessels 12 as shown in FIG. 1. The vessels 12 preferably have three ridges 26, or rudder-like projections, that run the majority of the longitudinal length of the bottom of the vessel 12. The ridges 26 act as rudders when the vessel 12 is moved through the water.
Referring now to FIG. 2, there is shown a top view of two [0050] frames 22 and two flotation vessels 12 of the two modules 11 shown in FIG. 1. A frame 22 circumscribes each vessel 12. The frame 22 is attached to the vessels 12 with the attachment means 24 (shown with dotted lines), which reside in the pockets 20 (shown generally with brackets).
Referring to FIG. 3, there is shown a perspective view of a preferred embodiment of the floating playground [0051] 10. The embodiment shows two modules 11 a and 11 b with various recreational implements attached. Module 11 a is attached to module 11 b with an attachment means 44. Referring to FIG. 3A, there is shown a partial, break away view of the attachment means 44 shown in FIG. 3. The attachment means 44 is preferably a hinge pin assembly 45. The assembly 45 comprises a pair of barrel hinges 45 a and 45 b, and a hinge pin 45 c. The barrel hinges 45 a and 45 b are preferably made of metal, and are attached to the frame 22 of the two modules 11 a and 11 b, preferably by a weld 47. Barrel hinge 45 a is a center hinge 45 a, attached to the frame 22 of module 11 a while hinge 45 b are top and bottom barrel hinges 45 b attached to the frame 22 of module 11 b. The modules 11 a and 11 b are together by bringing the two modules 11 a and 11 b together, then positioning module 11 a such that the center barrel hinge 45 a resides between the top and bottom barrel hinges 45 b. Once the center barrel hinge 45 a resides between the top and bottom barrel hinges 45 b, the hinge pin 45 c is slidably inserted through the top hinge 45 b, through the center hinge 45 a and then through bottom hinge 45 b. The process is repeated for the other attachment means 44 on the modules 11 a and 11 b, and then said modules 11 a and 11 b are connected together to form a floating playground 10. The attachment means 44 is preferably a hinge pin assembly 45, but can also be a latch, a clamp, a U-joint which allows two degrees of movement, but not torsional movement, a spherical end joint which allows three degrees of movement, or any other suitable means to those skilled in the art.
Referring again to FIG. 3, a floating [0052] vessel 12 is shown supporting each module 11 as a buoyancy base. The frames 22 are shown circumscribing the vessels 12. Preferably vertical posts 28 are shown supporting an upper deck 30 on one module 11 a while preferably vertical posts 28 support a trampoline 38 on the second module 11 b. In an alternative embodiment, the space 25 residing between the trampoline 38 and the frames 22 can be surrounded with a safety net (not shown), preferably around all sides of the trampoline 38, to prevent any injury to a user of the trampoline 38. The upper deck 30 comprises a platform 30 a, which rests on a plurality of cross-members 30 b. The cross-members 30 b are preferably made of the same material as the frame 22 and posts 28, and are attached by welding. The cross-members 30 b are supported by the preferably vertical posts 28. A lower decks 32 is shown covering the vessel 12 of module 11 a. The lower decks 32 is a protective covering, known to those skilled in the art, that functions to cover and protect the top of the vessel 12. The upper deck 30 of module 11 a also has a railing 36 attached to the cross members 30 b of the upper deck 30. Alternatively, the railing 36 can be attached to the preferably vertical posts 28. A slide 34 is attached to the railing 36 on the upper deck 30 and runs into the water. The slide 34 is supported by a slide attachment bracket 50 which attaches the slide 34 to the frame 22. A climbing net 46 is attached to the railing 36 and extends into the water. A basket ball hoop 48 is also attached to the railing 36. The trampoline 38 is supported by preferably vertical posts 28. Two ladders 40 a and 40 b are shown on the two modules 11 a and 11 b, respectively. Ladder 40 b extends from the trampoline 38 to the frame 22 and the other ladder 40 a extends from the back side of the upper deck 30 to the lower deck 32 beneath the upper deck 30. The end 42 of the flotation vessel 12 of module 11 b beveled. The beveled end 42 allows the floating playground 10 to glide across the water when the modules 11 a and 11 b are moved across the water. Ridges 26 act as rudders and help to prevent side to side movement of the modules 11 when the modules 11 are being moved. Movement is accomplished by attaching a rope (not shown) to the modules 11 and towing the modules 11 with a boat (not shown), or other suitable water craft. Alternatively, an outboard motor (not shown) can be attached to the module 11 a on the end opposite the beveled end 42 to make the modules 11 self-propelling.
It will be appreciated that the recreational implements shown in FIG. 3 are illustrative of a few of the recreational implements that can be attached to the [0053] modules 11. In addition to the implements shown in FIG. 3, other implements that cab be attached to the playground include, but are not limited to: a swing, a bathroom, a kitchen, curtains enclosing the deck, a canopy covering the deck, a tent covering the trampoline, an infant swing, an inflatable plastic log, a toy captains wheel, a toy periscope, a glass bottom section, a variety of floating toys for children, a set of monkey bars, a jungle gym, a climbing tube, a walk way or any other recreational implement.
Referring to FIG. 3B, there is shown an alternative embodiment of one [0054] module 11 of the floating playground 10. This embodiment shows a circular flotation vessel 12 a supporting a circular trampoline 38 a. The circular flotation vessel 12 a is preferably rotationally molded plastic filled with foam with an opening 17 in the center to form a doughnut shape. In the circular embodiment, a frame 22 a is used to attach preferably vertical posts 28 a to the trampoline 38 a. A ladder 41 is attached to the frame 22 a and trampoline 38 a to provide access to the trampoline 38 a.
Referring to FIG. 4, there is shown a top view of the preferred embodiment of the floating playground shown in FIG. 3.

Applicant's floating playground is supported by a durable, foam filled, plastic vessels 12 that do not require inflating. The foam also ensures that if the vessel were to be damaged, the vessel 12 will not fill with water and retain its buoyancy.
Also, because applicant's floating playground [0069] 10 is modular, an unlimited number of recreational toys can be attached together to form a floating playground 10. Applicant's floating playground 10 is also movable. Therefore, a user of the playground 10 can connect and disconnect modules 11 as desired and move the modules 11 to a different location. In essence, the applicant has conceived of a way to build a playground 10 on the water and interchange the toys on the playground in as many combinations as desired.
The phrase “uppermost portion of the floatation means” as used herein shall refer broadly to the concept of some portion of the vessel that is providing buoyancy, and not to any attachments residing on or connected to said vessel that do not aid in buoyancy or floatation. [0070]
A propelling means for propelling the floating playground [0071] 10 from one location to another upon a body of water is within the scope of the present invention. Such a propelling means may include any suitable motor, engine, towing device, or other suitable device now known or later discovered, that is capable of propelling the floating playground 10 from one location to another upon a body of water.
It is to be understood that the above-described arrangements are only illustrative of the application of the principles of the present invention. Numerous modifications and alternative arrangements may be devised by those skilled in the art without departing from the spirit and scope of the present invention and the appended claims are intended to cover such modifications and arrangements. Thus, while the present invention has been shown in the drawings and fully described above with particularity and detail in connection with what is presently deemed to be the most practical and preferred embodiment(s) of the invention, it will be apparent to those of ordinary skill in the art that numerous modifications, including, but not limited to, variations in size, materials, shape, form, function and manner of operation, assembly and use may be made without departing from the principles and concepts set forth herein.
