Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




This invention relates to inflatable games, and more particularly to an inflatable game that incorporates features designed to suspend people above ground for fun and entertainment.




2. Description of the Related Art




For many years, inflatable games have amused and entertained young and old persons alike. The typical inflatable game is a large, flexible air-filled structure taking on a variety of shapes such as a castle, a pyramid, a pirate ship, and the like. Most inflatable games have at least one air-filled horizontal mattress upon which people, typically children, can jump and bounce. The air-filled jumping surface typically provides spring back making trampoline-type play possible, such that users can jump and bounce to higher heights than normal. The inflatable games are usually large enough for multiple persons to use at the same time. In some instances, the inflatable games can be twenty (20) feet high and one hundred twenty (120) square feet wide. Furthermore, since the inflatable structures are filled with air and the surfaces are relatively soft, users can fall on the inflatable mattress with little fear of injury. Hence, the inflatable games provide a great deal of safe entertainment especially for young children.




In recently years, the increasing popularity of inflatable games has led some game manufacturers to make inflatable games that are more sophisticated and contain more features than just an inflatable mattress. For instance, some inflatable games now include slides, obstacle courses, and other features for playing physically challenging games like tug-of-war. In addition to jumping and bouncing, these alternative inflatable games allow for a variety of different activities, all of which could be engaged with little fear of injury. As more features are added, the user is treated to an ever widening variety of games and activities to engage in, thereby enhancing the user's experience with the inflatable games. In an effort to keep their customers entertained, inflatable game manufacturers are constantly seeking more features to include in their games.




Moreover, it is also generally known that the added elevation and the thrill of being suspended in midair can be very exciting for people seeking amusement. Consequently, zip lines and suspended bridges have always been popular activities at amusement parks, fairs, and carnivals. However, Applicant is not aware of any inflatable game that incorporates features designed to suspend people in midair. This may be partly due to the difficult of utilizing inflatable structures to structurally support a person suspended in midair. Inflatable structures are generally too soft and pliable to withstand the load of the weight of the suspended structure loaded together with the person. In fact, the side walls of most conventional inflatable structures are likely to sag and crumble under the weight of a person riding for example a zip line. Hence, it will be appreciated that there is a need for an inflatable game that incorporates features that can suspend a person in midair. To this end, there is a particular need for an inflatable structure that is designed to withstand the load of the combined weight of a suspended structure together with a person hanging from the structure.




SUMMARY OF THE INVENTION




The aforementioned needs are satisfied by the snow sliding apparatus of the preferred embodiments of the present invention. In one aspect, the preferred embodiments provide an inflatable game that incorporates an inflatable structure in conjunction with a suspended feature that is configured to suspend a person in midair over the inflatable structure. In one embodiment, the suspended feature is supported by two inflatable supporting structures wherein the inflatable supporting structures are dimensioned to support the weight of the suspended feature and the person. In one embodiment, the ratio of the width to the height of the supporting wall is at least 1 to 2 so as to inhibit the supporting wall from sagging or toppling over. Preferably, the supporting wall has sufficient mass so that it is less likely to sag when the suspended feature is being used. In one embodiment, the suspended feature comprises a zip line. In another embodiment, the suspended feature comprises a suspended bridge.




In another aspect, the preferred embodiments provide an inflatable game comprising an inflatable mattress and a suspended feature that extends over the inflatable mattress. In one embodiment, the suspended feature comprises a zip line that is attached to rigid structures positioned adjacent the inflatable mattress. In another embodiment, the suspended feature comprises a suspended bridge that is attached to rigid structures positioned adjacent the inflatable mattress.




In yet another aspect, the preferred embodiments provide an inflatable game that is designed to suspend a person in midair over a cushioned surface. In one embodiment, the person can be suspended via a tie line over a horizontal inflatable structure. In another embodiment, the person can be suspended via a hollow tube over a horizontal inflatable structure. These and other advantages of the present invention will become more fully apparent from the following description taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




Reference will now be made to the drawings wherein like numerals refer to like parts throughout.

FIG. 1

illustrates an inflatable game


100


of one preferred embodiment. As shown in

FIG. 1

, the inflatable game


100


generally comprises an inflatable structure


102


that is filled with a fluid such as gas. In one embodiment, the inflatable structure


102


comprises a plurality of flexible sheets


104


that are assembled together in a known manner. Preferably, the sheets


104


are sewn, glued, sealed or otherwise attached together in a manner such that seams between the individual sheets


104


are air-tight so as to inhibit leakage of air. The sheets


104


can be made of vinyl or other suitable material. The size and shape of the sheets


104


and their arrangement, once assembled, define the general shape of the inflatable structure


102


. It is understood that the inflatable structure


102


can take on a variety of different shapes, such as castles, pirate ships, pyramids, and the like, without departing from the spirit of the invention.




In the embodiment as showing in

FIG. 1

, the inflatable structure


102


comprises a three-dimensional U-shaped structure having a horizontal mattress


106


that extends between two vertical walls


108




a


,


108




b


. Preferably, the horizontal mattress


106


is dimensioned and inflated in a manner such that people can fall or jump on the mattress


106


and be sufficiently cushioned by the air contained therein. In one embodiment, the horizontal mattress


106


is about 6 feet thick, 54 feet long, and 24 feet wide. However, it can be appreciated that the dimension of the inflatable structure can vary without departing from the scope of the invention.




As

FIG. 1

further shows, a cable


110


extends between the two vertical walls


108




a


,


108




b


. The cable


110


functions as a zip line along which people can slide from one end to the other. Preferably, the cable


110


is made of a high-strength material capable of withstanding many times the average weight of an adult human. Moreover, the cable


110


preferably has a low elasticity such that it does not flex considerably under regular loading. In the embodiment shown, the ends


112




a


,


112




b


of the zip line


110


are attached to the two vertical walls


108




a


,


108




b


in a manner such that the zip line


110


is sloped at an angle so as to enable a person to slide from the first end


112




a


of the line to the other


112




b


. Advantageously, the zip line


110


extends along the first distance


114


so as to allow a person


180


to travel over the first distance


114


while being suspended midair above the inflated mattress


106


which provides a safe cushion for the person to fall on.




In one embodiment, the vertical walls


108




a


,


108




b


are designed in a manner such that they will only sag slightly when the zip line


110


is in use. Preferably, the ratio of the width to the height of each vertical wall


108




a


,


108




b


is at least 1 to 2 so as to inhibit the vertical walls


108




a


,


108




b


from sagging or toppling over when the user is hanging from the zip line


110


. However, it is understood that the dimensions of the walls comprising the inflatable structure can vary depending upon the desired final shape, and such variance does not depart from the spirit of the invention. In some embodiments, one or both vertical walls


108




a


,


108




b


can be supported by additional inflatable structures that are positioned adjacent to the vertical walls


108




a


,


108




b


so as to provide additional mass for the structure, which further reduces the likelihood of sagging or toppling from the weight of the person hanging from the zip line. For example, each vertical wall


108




a


,


108




b


can be connected to an additional inflatable mattress (not shown) positioned behind the walls.





FIG. 1

also shows the manner in which the zip line


110


is attached to the vertical walls


108




a


,


108




b


of the inflatable structure


102


. In the embodiment shown, each end


112




a


,


112




b


of the zip line


110


is threaded through a plurality of retainers


116


such as metal rings that are attached to an interior surface


120


of the vertical walls


108




a


,


108




b


at an appropriate height so as to suspend the zip line


110


above the inflatable mattress


106


. Advantageously, the use of multiple retainers distributes the load that is induced on the vertical walls


108




a


,


108




b


when the zip line


110


is in use. However, in other embodiment, a single retainer can be used to attach the ends of the zip line to each interior surface of the vertical walls or the end of the zip line can be directly attached to the vertical wall. As

FIG. 1

further shows, an opening


118


is formed in the vertical wall


108


wherein the opening


118


extends from an interior surface


120


to an exterior surface


132


of the vertical wall. Preferably, the opening


118


serves as a place where people can stand before sliding down the zip line


110


.




Moreover, in some embodiments, a sliding member


122


such as a harness can be detachably attached to the zip line. Preferably, the sliding member


122


is configured to carry a person while the person slides along the zip line


110


. In another embodiment, the sliding member


122


also includes a perch


124


for a person to sit on while the sliding member


122


moves along the zip line


110


. In one embodiment, the perch


124


also comprises additional retaining straps (not shown) which keep the rider


180


secured to the sliding member


122


even when the rider


180


is not actively holding on to the sliding member


122


. This embodiment of the sliding member


122


is relatively safe because the retaining straps inhibit the person from inadvertently falling out of the sliding member


122


during travel. In other embodiments, the sliding member


122


comprises a bar that can be attached to the zip line


110


in a known manner. Preferably, the bar is configured for the person to hold onto while sliding along the zip line


110


. Using a bar as the sliding member allows more people to ride along the zip line


110


in a less amount of time because users


180


simply have to grab the bar before moving along the zip line


110


. Moreover, in addition to gliding down the zip line, the person


180


can also climb and hang on the zip line


110


while being suspended in midair, giving the user


180


an enjoyable play activity.




The inflatable structure


100


of

FIG. 1

incorporates the zip line


110


to thereby provide the rider


180


with a wider array of activities than those currently available in the art. For example, the sliding member


122


can move the person


180


along the length of the zip line


110


under the force of gravity. If the slope of the zip line


110


is large, the user


180


may reach considerable speeds. Furthermore, the person


180


can even complete the travel by dropping onto the soft, bouncy horizontal mattress


106


of the inflatable structure


102


. The zip line


110


can be used in a competitive game, wherein the person


180


, while strapped into the sliding member


122


, is challenged to move up the zip line


110


using only arm strength. If there are several people


180


, the people


180


could compete and try to achieve this task in the shortest amount of time. Moreover, people


180


can also climb along the zip line


110


without using the sliding member


122


and drop from the elevated height onto the horizontal mattress


106


for an exciting free fall. Thus, addition of the zip line


110


allows for additional activities to thereby increase people's


180


enjoyment of the inflatable game


100


. Moreover, it can be appreciated that the inflatable structure shown in

FIG. 1

can also represent part of a larger inflatable structure.




In another embodiment not shown, the zip line is not attached to the inflatable structure. Instead, the zip line is attached to separate structures that are positioned near the inflatable structure, and the zip line extends over the inflatable structure and allows the same types of activities described hereinabove. For example, in one embodiment, the zip line is attached to vertical poles positioned at opposite ends of the inflatable structure such that the zip line extends over the inflatable structure. As such, this embodiment of the inflatable structure advantageously inhibits sagging or toppling over of the zip line regardless of the dimensions of the inflatable structure.





FIG. 2

provides a schematic illustration of another inflatable game


200


. The inflatable game


200


comprises an inflatable structure


202


similar to the inflatable structure


102


shown and described in FIG.


1


. Moreover, the inflatable game


200


comprises a suspended bridge


204


that extends between two vertical walls


206




a


,


206




b


of the inflatable structure. As will be described in greater detail below, the suspended bridge


204


provides the players with an even wider variety of activities to engage in and thereby increases the player' enjoyment of the inflatable game.




In one embodiment, the inflatable bridge


204


comprises a hollow tube, made of flexible material such as vinyl. Preferably, the bridge


204


is sufficiently large enough to allow a person to crawl through or in some embodiments, to allow a person to walk through in a substantially upright posture. The tunnel can be attached to the inflatable structure via a number of well known attachment processes such as sewing or through the use of adhesives.




In this embodiment, both vertical walls


206




a


,


206




b


further comprise a tunnel


208




a


,


208




b


. The tunnel


208




a


,


208




b


is preferably a hollow tube having a diameter large enough to allow a person to walk therethrough in an upright position. Each tunnel


208




a


,


208




b


extends from an exterior surface


210




a


,


210




b


to a respective interior surface


212




a


,


212




b


so as to provide access to the bridge


204


. The tunnels


208




a


,


208




b


are preferably aligned with a first and second end


214




a


,


214




b


of the bridge


204


in a manner such that the tunnels


208




a


,


208




b


and the bridge


204


form a uniform walkway between the vertical walls


206




a


,


206




b


. As is also shown in

FIG. 2

, a ladder


218


can also be used to enable a person


280


to climb to the tunnel


208




a


,


208




b


leading to the bridge


204


.




As shown in

FIG. 2

, the bridge


204


extends along the first distance


220


at an elevated height above the inflatable structure


202


, and as such, the bridge


204


provides the person with a larger array of activities than those currently available in the art. For example, the person


280


can walk or crawl from one section of the inflatable structure to another while suspended high above ground. Furthermore, if the bridge


204


is fixed to the inflatable structure


202


at a slope; the person


180


can use the bridge as a slide that is suspended in midair. Similarly, a sloped bridge can also be used in a competitive game in which people attempt to climb up the bridge


204


in the shortest amount of time. Advantageously, these added activities allow the person


180


to more fully enjoy the inflatable game


200


.




Alternative embodiments of the bridge


204


comprise a plurality of viewing windows


222


which are openings created in the bridge


204


at intermittent distances. The viewing widows


222


allow a person to look out over the inflatable structure


202


as the person moves through the bridge


204


. Similarly, the sides of the bridge


204


, in other embodiments, an also comprise a see-through mesh material through which people can look out over the inflatable structure


102


so that people in the bridge are more aware of their elevation, which is likely to produce more excitement.




Other embodiments of the bridge comprise an elongated horizontal surface with sidewalls extending from the edges of the horizontal surface, but which is open to the sky. As before, this allows people to look out over the inflatable structure and get a sense of the elevation. Also, depending on the elevation of the bridge, people might be able to safely drop from the bridge to the cushioned horizontal mattress


206


for a thrilling free fall. Thus, these alternative embodiments of the suspended bridge produce added enjoyment to the inflatable structure game.




Still in other embodiments, the bridge is not connected to the inflatable structure. The bridge can be attached to rigid structures, such as elevated platforms, lying adjacent to the inflatable structure, and a portion of the bridge extends over the inflatable structure. As such, a person can participate in the same activities described above. Also, as situated, the bridge is less likely to sag or topple over when the user is on the bridge.





FIG. 3

illustrates another embodiment of an inflatable structure


300


incorporating a suspended bridge


302


. As shown in

FIG. 3

, the inflatable structure


300


comprises a front and rear wall


304


,


306


with the suspended bridge


302


extending therebetween. The front wall


304


can be further supported by an additional structure


308


, which in this embodiment is in the configuration of a skull. The additional structure


308


is attached to the front wall


304


in a manner so as to provide added mass to the inflatable structure


300


so as to inhibit the front wall


304


from sagging or toppling over under the weight of people suspended by the bridge


302


. As

FIG. 3

further shows, the rear wall


306


is also supported by a slide


310


that is attached to the rear wall


306


in a manner so as to inhibit the rear wall


306


from toppling over.




It will be appreciated that the inflatable game of the preferred embodiments can incorporate both a suspended bridge and a zip line without departing from the spirit of the invention. Such an embodiment would allow a person to advantageously engage in all of the activities described above with the same inflatable game. Advantageously, the inflatable structure used in conjunction with the suspended features described above allow the user to engage in new activities, which are not available on current designs of inflatable game. Advantageously, these new activities provide added enjoyment to the user of the inflatable game.




Although the foregoing description of the preferred embodiment of the present invention has shown, described and pointed out the fundamental novel features of the invention, it will be understood that various omissions, substitutions, and changes in the form of the detail of the apparatus as illustrated as well as the uses thereof, may be made by those skilled in the art, without departing from the spirit of the invention.
