DETAILED DESCRIPTION

In accordance with a first embodiment of the invention, FIG. 1 illustrates a trampoline play system 100 comprising a trampoline rebounding surface 110 elevated above the ground by the trampoline support frame 120, where the periphery of the trampoline rebounding surface 110 is connected to the inner circumference of a trampoline support frame 120 by springs 130. The trampoline play system 100 also preferably comprises a safety enclosure 140 wherein the player jumping on rebounding mat 110 is confined within the interior space 145 defined by safety enclosure fence 141. Safety enclosure fence 141 is preferably supported by a series of substantially vertical support posts 142 via interconnecting straps or brackets, illustrating schematically as component 143. It should be appreciated that the attachment method need not be limited to concealed or hidden connectors, as elastic cords disposed above the rebounding surface and connecting to the supports posts, frame or safety enclosure and can also be used to separate players or as an element that partially defines the games or contest.

In one embodiment, a device according to the instant invention takes the form of a trampoline bed accessory 150 being disposed on or over rebounding surface 110 of the trampoline system of FIG. 1. In FIG. 1 accessory 150 is a substantially planar device or sheet and is optionally secured to the trampoline rebounding mat 110, springs 130 or support frame 120 via fasteners schematically illustrated as component 151. The sheet, as well as other embodiments described below, can be attached to the trampoline rebounding surface by physical attachment, such as adhesive tape or “VELCRO” strips, or similar and related loop and hook fabric fasteners, applied to the margin of the sheet that extend to overlap the rebounding surface, adhesive or tacky pads on the underside of the flexible sheet, or elastic cords that reach to the edge of the rebounding mat for attachment to the frame, springs, on an annular spring cover, or extend under the rebounding mat to connect opposite sides of the flexible sheet. Alternatively, the flexible sheet may be secured by magnet attraction, for example by adhering strips of magnetic particle striping to the underside of the rebounding surface intended to attract, and therefore secure, a flexible sheet that is at least partially constructed using magnetic fillers in the resin or fabricated to include similar magnetic strips, or by eyelets or the like that can be used to connect the flexible sheet to the trampoline springs, frame, spring pad, enclosure poles, etc.

Accordingly, trampoline bed accessory 150 is sufficiently durable to resist damage from repeated impacts of player jumping on the trampoline rebounding surface 110. FIGS. 2-3 illustrate alternative embodiment's invention where the trampoline bed accessory retains water for wet play. As will be further described with respect to other embodiments, the trampoline bed accessory's alternative embodiments include various forms of game mats, which may include various features and components that enable various forms of competitive, interactive or educational play. While some embodiments of the invention are particularly adapted for use on a trampoline, the environment and methods of use are not limited thereto.

FIG. 2A schematically illustrates the water retaining properties of trampoline bed accessory 200 and the corresponding deformation of trampoline rebounding mat 110 in response to the weight of the retained water 201. FIG. 2B is a plan view further illustrating elements of the construction of trampoline bed accessory 200 associated with, among others, the water retaining properties. The trampoline bed accessory 200 has central zone 210 that is not water permeable. The central zone 210 is surrounded by an outer zone 230. Outer zone 230 is water permeable such that the quantity of retained water 201 and the corresponding deformation of the trampoline rebounding mat 110 are appropriately limited within suitable conditions for dampening the rebounding response. The flexible sheet that forms either a trampoline accessory of game mat 200 is preferably porous for water drainage along at least some of the perimeter, and preferably non-porous for retaining water in the central region. However, in alternative embodiments, non-planar devices according to the invention may be entirely non-porous or may have porous or non-porous portions/spots in various patterns. In other embodiments, the device may be entirely porous, for example, when water retention is not intended for play or educational games.

Although the quantity of water 201 is not critical for individual wet play activities, such as splashing spectators while jumping, a controlled quantity of water provides a benefit in that it dampens the trampoline rebounding surface response. A dampened response makes the trampoline more suitable for use by players, who can enjoy jumping and splashing activities with greater safety, without need to modify or adjust the spring system. Thus, the trampoline system can be returned to normal use simply by dumping, draining or pumping out the water or removing the trampoline bed accessory/game mat. Accordingly, the mat may also includes a drain hole or plug at the edge or lower surface that can be released or removed at the end of use.

When the planar embodiment of the device 150 in FIG. 1 is intended for wet play, as shown in FIG. 2A, a player may initially stand on the center of the trampoline bed accessory 200 to provide the initial deformation to the rebounding surface 110 such that water added to the central zone 210 will be retained until the accumulated weight of the water is sufficient to retain the illustrated concave shape in the absence of a player.

An alternative form of a sheet that forms a trampoline accessory 200 might also have surface regions with a concave areas to retain water, inflatable regions that extend from the sheet to cushion landings or to increase visibility of target areas or landing areas Further, in preferred embodiments the upper surface of trampoline bed accessory 200 is appropriately textured to have anti-slip properties enabling safer wet play such as under the configuration illustrated in FIGS. 2, 3, 4 or 5C.

Accordingly, the trampoline bed accessory 200 is preferably fabricated from flexible sheet(s) of material, such as materials used to form trampoline rebounding surface, (but may include alternative materials,) for example fabric, non-woven fabric, PVC coated fabric and the like, wherein the open weave of the fabric is porous and a coated region or laminated film region is non-porous. Alternative coatings include plastic film or sheeting, rubber, polyurethane, silicone and the like. Further, the fabric may be elastic, being fabricated from “LYCRA” or other elastomeric fibers. In addition, 200 may be fabricated so that it is padded.

FIG. 3 illustrates an alternative embodiment of the invention wherein the trampoline bed accessory 300 includes a peripheral wall 310 for retaining water The peripheral wall portion may substitute for or be in addition to the porous fabric region, as in some embodiments it is desirable for the game mat to extend to the edge of the rebounding surface, for either attachment thereto, or to provide a wider play area with various forms of printed indicia. The game mat can extend beyond the circumference of the trampoline frame or anywhere in between.

Alternatively, as shown in FIG. 3, accessory 300 includes a retaining wall 310 that is upright but is preferably soft, conformal or optionally filled with air or water (as further described in FIG. 4A) so that the center region can be filled with water while the trampoline rebounding surface deforms into a concave profile. The center of the game mat may also comprise a planar cavity that initially fills with and retains water while the rebounding mat 110 is undergoing deformation. Accordingly, the upper surface of the cavity is optionally submerged by providing additional water after the rebounding mat is deformed by the weight of the water in the cavity.

FIG. 4A illustrates an alternative embodiment of the trampoline bed accessory for either wet or dry play of the game mat 401 while it is filled with water as peripheral wall 414 retains sufficient water to initiate the deformation of rebounding mat 110. Thus, for wet play water peripheral wall 414 is initially filled with water via portal 441 deforming the rebounding mat, after which water is directed to the central cavity between the peripheral wall to provide an open pool of water for jumping and splashing. Alternatively, the trampoline bed accessory 401 may include other features associated with substantially dry play, such as a game mat, wherein the water retention (in either or both wall 414 or central cavity) is primarily to dampen the response of the rebounding mat 110, further enabling players to participate in the game mat activities more safely. In a preferred embodiment, the central region defined by peripheral wall 414 demarks a region of the game map 401. In a more preferred embodiment the accessory or game mat 401 includes an outer peripheral zone 445 having visual indicia 446 to indicate spacing for playing games, and would thus extend to or even beyond the edge of the rebounding mat.

FIG. 4B illustrates another alternative embodiment in which the trampoline bed accessory or game mat 402 comprises plural layers of flexible and/or elastic sheets that are sealed at the edge to form a substantially closed cavity 415. Sides or edges of game mat 402 are optionally formed by sealing together at least an upper surface 405 and a lower surface 410; the lower surface intended to contact either the rebounding surface or another horizontal surface for support. Thus, players can optionally jump on the rebounding mat or onto various locations that may be marked on the upper surface 405 of game mat 402. The interior cavity 415 is filled with water via portal 442. In more preferred embodiments, game mat 402 includes a plurality of water squirt nozzles, 431 and 432 in FIG. 4C. The squirt nozzles are oriented to either spray or squirt water upward, that is onto the player or other players, as well as laterally, that is onto spectators or players of interactive games.

Squirt nozzle 432 may include a siphon tube extension 440 attached to the inlet side of the spray nozzles to collect water at the bottom of cavity. Thus, siphon tube extension 440 is preferably flexible and extends toward the bottom of water containing cavity 415, providing access to the water regardless of the fill level of cavity 415.

In another embodiment, illustrated in FIG. 5C, game mat 502 is further subdivided or otherwise configured to provide individual sub chambers 540, 550 and 560 within cavity 515. Such sub chambers can have one or more spray nozzles 531 such that a player can selectively discharge water from one or more nozzles by landing on the appropriate region of the upper surface 505 of game mat 502. Spray nozzles may be connected to an external pressurized water source. Also, siphon tubes, such as 552, may connect from the sub chambers to spray nozzles located at a distance from the operative landing zone above the sub chamber, as might be marked on the upper surface 505 of game mat 502. The sub chambers would receive water through an orifice or valve in fluid communication with the main cavity 515 or another chamber, as the valve or orifice would normally close upon internal pressure arising from the player landing on the zone above the sub chamber. Accordingly, these configurations enable various forms of competitive and interactive play wherein players attempt to adjust the location and the time of their landing on the game mat 502 in order to more successfully drench other players with water, as well as avoiding becoming the target of another player's external operation of the spray nozzles.

It should be appreciated that as other aspects of the invention, more fully described below, include marking distinct regions with printed indicia, such as correspond to numbers, letters, symbols and the like, such indicia may be combined with the operative characteristics of squirt or spray nozzles, sound makers, bubble makers, visual displays, or light emitters. Alternatively, the operative features are readily revealed, and thus optionally featured, by providing a transparent upper layer and/or sub-cavity covers. Further, in accordance with other aspects of the invention, any of the water retaining trampoline accessories or game mats of FIGS. 1-4 can also include such printed indicia independent of the surface texture or porosity of the region, and may be used independent of a trampoline. It may be used on the ground, in a pool, on the bouncing surface of an inflatable structure.

FIGS. 5A and 5B illustrates further embodiments of the invention wherein regions of the game mat 501 are visually distinct to the player, as in the plan view shown in FIG. 5A, having printed indicia corresponding to numbers, letters, symbols, borders and the like. FIG. 5B illustrates a more preferred embodiment of the invention wherein an auditory or visual output is provided to players and/or spectators to indicate that the player has made contact with one or more distinct regions of the game mat during play.

Thus, in the plan view of trampoline accessory/game mat 501 in FIG. 5A regions or zones labeled 510, 511, 512, 513 and 514 are operatively connected to a visual display 540 and/or loudspeaker 550 to provide players, as well spectators, with an output in response to the player landing on the visual indicia associated with the zone. FIG. 5B is an elevation of the cross-section corresponding to reference line B-B′ in FIG. 5A to illustrate the juxtaposition of pressure or impact transducers 520, 521, 522 in correspondence with the location of visual indicia 513, 512 and 511 respectively. An optional amplifier or signal processor 530 receives the output from transducers 520, 521 and 522 via connecting circuit 535.

Accordingly, circuit 531 of game device mat 501, shown in plan view in optionally includes controllers along with electronic output devices, which may include a game control device for spectator or automatic control of the visual display or loudspeaker, illustrated in FIG. 5B, depending on the nature of the games or play activity. Such games may utilize either alone or in combination loudspeaker 550 or a visual display 540. The visual display may be digital or analog, and can provide the players with scores, as well as play instructions, such as instructions to land on a particular letter symbols or icons, either in response to a question, a direct instruction or command. Additionally in alternative embodiments, more fully described with reference to FIG. 6 below, the visual display is coincides with the zone on the surface of the game mat. Further, the visual indicia may be varied by replacing an overlaying sheet, and thus providing the option of selecting from a variety of games appropriate for different age or skill levels, including competitive interaction between the player within the trampoline enclosure and the spectators, as well as pool and splash games not associated with a trampoline.

In yet another embodiment, the visual indicia of FIG. 5A can represent a calculator for learning math facts or language skills. Bouncing off a particular number symbol could generate a corresponding audio or visual output of a number or mathematical operation. Both the player inside the safety enclosure and observers can participate in interactive play or practice their multiplication tables, as well as addition, subtraction or division and word games. Spectators might call out instructions, or be required to provide the correct answer to the calculations or words selected by the jumping player.

Game mat can also have multiple patterns for playing jumping games. The patterns can also be used as place locators for marking indicia or applying detachable indicia used to play games that utilize numbers, words, cards and symbols, etc. For example, in one embodiment the pattern may consist of an array of hook and loop fabric fasteners intended to receive a variety of discrete separate marks having a corresponding fastening component disposed on their underside. The patterned array thus permits the removal and secure replacement of separate marks either as part of, or to correspond with the play activity.

While the visual display is optionally deployed to provide correct answers to games, such as the aforementioned calculations, an alternative use is to tally the score of games, or alternatively provide a player with an indication of the number of bounces, elapsed time and like parameters related to athletic performance.

In additional embodiments, the planar game mat is combinable with either a shallow splash pool or more substantial pool structure independent of use with a trampoline structure. In such embodiments, the planar mat is not required to be flexible, and can be somewhat rigid, as it would be disposed at the bottom of the pool. According, the printed indicia and other features previously described with respect to recreational activities on the trampoline rebounding surface can take place in either a temporary or more permanent pool, i.e. a permanent or in ground pool as well as a temporary or splash pool and the like.

While the invention has been described in connection with a preferred embodiment, it is not intended to limit the scope of the invention to the particular form set forth, but on the contrary, it is intended to cover such alternatives, modifications, and equivalents as may be within the spirit and scope of the invention as defined by the appended claims.
