Description




FIELD OF THE INVENTION




This invention relates to inflatable structures generally, and more specifically to an inflatable tent structure having an integrally attached inflation pump.




BACKGROUND OF THE INVENTION




Inflatable tents and other inflatable enclosures are known. A simple example is shown in U.S. Des. Pat. 396,087 to Liu.




Certain inflatable houses have an inflatable support structure and an inflatable interior chamber. U.S. Pat. Nos. 5,970,661 to Bishop et al. and 4,031,674 to Rand are illustrative of such structures. Other structures have inflatable support members only, and do not have an air pressurized interior chamber. U.S. Des. Pat. 216,352 to Martin et al. illustrates one such structure.




In all cases, however, inflatable tent structures either require the connection of a separate inflation means, or are dependent upon the use of a separate power source. For example, both the Rand '674 and the Bishop et al. '661 structures require a connection to an electric power source to operate the inflation fan. Another example is shown in U.S. Pat. No. 6,192,633 to Hilbert, wherein a separate compressed air tank must be connected to a manifold to inflate the support structure. Similarly, in U.S. Des. Pat. 361,364 to Winters, a nozzle is provided for connection to either a separate inflation pump or for engagement by a person's mouth depending on the size of the inflatable structure. Other conventional inflatable structures such as beach balls, pool floats, travel pillows and the like are all provided with a nozzle or the like for attachment to a separate inflation means.




For portable, transportable inflatable structures that are dependent on ancillary inflation means, whether such means is an electrical pump or a foot-operated bellows-type pump, such inflation means may limit and restrict the ability to use such structures in any desired environment. For example, it would be impossible to use an inflatable tent in the back woods if such tent requires the use of an electrical inflation pump. Similarly, it may be inconvenient to have to bring a mechanical type inflation pump along with the inflatable housing structure particularly if the inflation pump is being used for other items.




Thus, there is a need to provide an inflatable structure that is not dependent on ancillary inflation means and that does not require a user to blow into an air nozzle. Such need is met by the inflation apparatus of the present invention having an integrated inflation means that expedites inflation, is quick and easy to operate, and does not require a connection to an outside power source. The inflatable tent of the present invention is easily transportable and can be used in any environment without concern for supplementary energy sources and without requiring the user to exhaust lung capacity.




SUMMARY OF THE INVENTION




A tent or the like having an inflatable support structure comprises a manually operated inflation pump associated with the inflatable support structure and the tent or the like. The pump is fixedly attached to the tent such that the tent and the pump form a single, integrated unit. The pump is preferably movable between a storage position and a use position. While in the storage position, the pump is also preferably is hidden or camouflaged by the tent environment. In addition, the tent structure may be enhanced with sound means or other means for increasing enjoyment and use of the tent.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




The following detailed description is of the best mode or modes of the invention presently contemplated. Such description is not intended to be understood in a limiting sense, but to be an example of the invention presented solely for illustration thereof, and by reference to which in connection with the following description and the accompanying drawings one skilled in the art may be advised of the advantages and construction of the invention. In the various views of the drawings, like reference characters designate like or similar parts.





FIG. 1

illustrates an inflatable tent


10


of the present invention. The term “tent” as used herein is not intended to be construed in a limiting fashion, such that only actual “camping tents” or the like are contemplated. For instance, the inflatable tent


10


of the present invention may be in the form of a camping tent as shown in

FIG. 1

, or a house as shown in

FIG. 2

, or any structural design suitable for use as an inflatable structure. In addition, while most of the illustrations of the present invention relate to play enclosures, it is not intended that the application be limited to enclosed structures or structures suitable for children. For purposes of illustration and explanation, however, the inflatable structure of the present invention will be illustrated as a camping tent or a child's play house as shown in

FIGS. 1 and 2

.




The inflatable tent


10


of

FIG. 1

comprises an inflatable base


20


, suitable for positioning on a support surface, and a plurality of inflatable walls


30


. Similarly, the inflatable tent


100


of

FIG. 2

comprises an inflatable base


120


and a plurality of inflatable walls


130


. While the tents are illustrated with two or more walls


30


,


130


, it will be understood that any number of walls will be operable as long as the tent is inflated for its desired purpose. The base


20


,


120


and walls


30


,


130


define an inflatable support structure formed by a network of interconnected inflation passages. When inflated, the inflatable support structure preferably enables the tent to form a freestanding enclosure, with suitable material


35


,


135


spanning between the walls


30


,


130


and base


20


,


120


to further define such enclosure.




More specifically, the inflatable support structure of the present invention is preferably constructed with a combination of single layered and double layered, heat-sealed PVC (polyvinylchloride) portions


40


,


140


and


50


,


150


respectively. Materials having other chemical compositions are clearly contemplated. The single-layered portions


40


,


140


preferably form the wall material


35


,


135


, while the double-layered portions


50


,


150


preferably form the base


20


,


120


and wall chambers


30


,


130


. In some instances mesh or nylon fabric inserts


60


could replace the single layered PVC portions


40


. The double-layered, heat-sealed portions or bladders, when filled with an inflation fluid such as air, create structural chambers that are strategically positioned to define and give structural form, creating a three-dimensional structure.




The tent of the present invention is provided with inflation means


300


integrally associated with the network of interconnected inflation passages. Such inflation means


300


is preferably constructed as a manually operated foot pump


305


(

FIG. 1

) integrally associated with the inflatable base


20


of the tent structure that serves to inflate and deflate the inflatable support structure of the tent. The pump


305


is activated by an application of force upon the pump upper surface


308


, which causes a compression of the pump interior (not shown) that results in the introduction of an inflation fluid such as air into the inflatable support structure. Repeated compressions of such pump results in the dispersion of fluid throughout the network of interconnected inflatable chambers until the tent structure is fully inflated. A switch


310


or the like provided on the pump enables a user to change the pump from an inflation mode to a deflation mode, wherein the airflow direction may be controlled as desired. While such means


300


is preferably connected directly to the inflatable structural support members, such means


300


may also service the interior of the tent structure if desired.




The inflation means


300


is integrated into the design of the tent and is preferably non-removable. Such means


300


is also preferably hingedly movable between a use position


320


, wherein the pump surface


308


is easily accessible to the foot of user for inflation and deflation, and a storage position


325


, wherein the pump surface


308


is disposed adjacent a wall of the tent structure and secured in such position by suitable securing means. Integrating the inflation means into the design of the tent is also preferable so that the inflation means housing does not appear to be an obvious feature of the overall tent appearance. For example, the pump


180


(

FIG. 2

) associated with the inflatable base


120


may take the form of a flower attached to the house


100


, so that the pump


180


appears camouflaged into the design of the house


100


. Pump


180


is operated in a similar manner to pump


305


.




While the inflation means of the present invention is illustrates as a foot-operated pump, it will be appreciated that such pump may be located in a position that is suitable for access by another part of a user's body. It will also be appreciated that other types of pumps that do not rely on the compression of a bladder will be operable. While it is preferable that the pump is integrally associated with the tent housing, it is not necessary that the pump is located directly adjacent the tent as shown. Furthermore, it is preferable that the inflation means is not dependent on alternative energy sources such as that provided by an electrical connection and/or such as that which would restrict use of the tent in a particular environment.




The inflatable structure of the present invention may also be adorned with visual images indicative of the particular design of the structure. For example, if the inflatable structure is in the shape of a house


100


as shown in

FIG. 2

, such house


100


might have siding


102


, shingles


104


on the roof


106


, a chimney


108


, windows


110


, a sunroof


112


, a mailbox


114


and the like, all of which are indicative of a house-type dwelling. Other images are clearly contemplated. As shown in

FIG. 3

, the inside of the structure


100


might also have images and designs


116


printed on the interior walls


137


. Similarly, a camping tent inflatable structure


10


as shown in

FIG. 1

might have camping tent features, such as a mesh roof and the like.




The inflatable structures


10


,


100


of the present invention may further comprise doors


70


(FIG.


1


),


170


(

FIG. 2

) that may have a variety of closure means. One example is illustrated in

FIG. 1

, wherein a simple loop-type closure


72


associated with the door


70


is strappable around a peg


74


provided on the tent body. Another example is illustrated in

FIG. 2

, wherein the door


170


is connected to the house


100


by a zipper closure, a Velcro® closure or something akin to a Ziploc® closure. Other closure means are clearly contemplated. Such closure means may be associated with any part of the inflatable structure that is capable of opening and closing, such as a door, window or the like.




The inflatable structure of the present invention may also comprise features designed to enhance the use and enjoyment of the structure. One example of such a feature includes the incorporation of sound means


200


into the walls of the structure. Such sound means


200


may be touch-activated, battery-operated inserts, in which case they may be serviced or replaced at some time in the future, or they may be integrally formed into the walls of the structure. In other words, accessible pockets


139


may be provided in the walls of the structure to house the sound means or the like, or such means may be integrally formed between layers of wall material at the time of manufacture. Such sound means may be operable by a button or switch, which button or switch may be indicative of the nature of the sound. For instance, a “WOF WOF” sound will be heard by touching an image


142


of a dog on an interior wall


137


of the house


100


of FIG.


3


. Similarly, a “CHIRP CHIRP” sound will be heard by touching an image


144


of a bird on an interior wall


137


of the house


100


. Similarly, a “HOO HOO” sound will be heard by touching an image


146


of an owl on an exterior wall


105


of the house


100


of FIG.


2


. Such sound means may be located throughout the structure as shown. Other use-enhancing features may be incorporated into the design of the tent as desired. Such features are not intended to be restricted to audio generators, but could also include means for generating effects that access the normal human senses of touch, taste, feel, sight and smell.




While the present invention has been described at some length and with some particularity with respect to the several described embodiments, it is not intended that it should be limited to any such particulars or embodiments or any particular embodiment, but it is to be construed with references to the appended claims so as to provide the broadest possible interpretation of such claims in view of the prior art and, therefore, to effectively encompass the intended scope of the invention.
