ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an inflatable tent for use in connection with tents. The inflatable tent has particular utility in connection with an inflatable tent with an integral air mattress.
2. Description of the Prior Art
Inflatable tents are desirable for quickly forming the shell of a tent. A common difficulty in setting up tents is preventing them from falling during construction. Inflatable tents take shape upon filling the structural airframe with pressurized air and allow the support frame to be easily inset due to the fact that the tent is self-supporting.
The use of tents is known in the prior art. For example, U.S. Pat. No. 6,167,898 to Larga et al discloses tent with integral air mattress that includes a base member composed of a bottom water resistant layer and at least one inflatable air mattress attached to the top of the bottom layer. A support frame extends upward from the base member and supports a fabric shell so as to define a tent interior. However, the Larga et al '898 patent does not have inflatable rib air passageways attached to the cover to support the tent while the support frame is being assembled.
Similarly, U.S. Pat. No. 5,642,750 to Brown et al discloses a tent having a continuous seamless peripheral surface and containing an integral self-inflating floor that has a spherical tent and an attached air mattress that self-inflates. However, the Brown et al '750 patent does not have inflatable rib air passageways attached to the cover to support the tent while the support frame is being assembled.
U.S. Pat. No. 4,531,330 to Phillips discloses a bed/shelter unit that comprises a panel of flexible tent material adapted to arch over the inflatable mattress from one side to the other. The panel has inflatable arches at its ends that are adapted when inflated to extend over the mattress from one side to the other. End closures at the ends of the tent hold the arches in an erected position with the panel drawn between the arches and the mattress. However, the Phillips '330 patent does not have inflatable rib air passageways attached to the cover to support the tent while the support frame is being assembled.
U.S. Pat. No. 5,660,197 to Boe et al discloses a tent with integrated inflatable mattress that has an outer sidewall supported by a par of flexible support poles. A double cushioned floor aligns with the bottom of the tent and is permanently sealed around the perimeter of the tent. An integral inflatable mattress is formed between the cushioned floor and a mattress upper surface. However, the Boe et al '197 patent does not have inflatable rib air passageways attached to the cover to support the tent while the support frame is being assembled.
Lastly, U.S. Pat. No. 5,502,927 to Hammerton discloses a portable, inflatable tent that has a semi-cylindrical cover portion that fastens to a planar base portion. The cover portion is provided with rib air-passageways that when inflated, support the cover portion in its semi-cylindrical configuration. However, the Hammerton '927 patent does not have inflatable rib air passageways attached to the cover to support the tent while the support frame is being assembled.
While the above-described devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe a inflatable tent that allows an inflatable tent with an integral air mattress. The Larga et al '898, Brown et al '750, Phillips '330, Boe et al '197 and Hammerton '927 patents make no provision for inflatable rib air passageways attached to the cover to support the tent while the support frame is being assembled.
Therefore, a need exists for a new and improved inflatable tent that can be used for an inflatable tent with an integral air mattress. In this regard, the present invention substantially fulfills this need. In this respect, the inflatable tent according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of an inflatable tent with an integral air mattress.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of tents now present in the prior art, the present invention provides an improved inflatable tent, and overcomes the above-mentioned disadvantages and drawbacks of the prior art. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved inflatable tent and method which has all the advantages of the prior art mentioned heretofore and many novel features that result in a inflatable tent which is not anticipated, rendered obvious, suggested, or even implied by the prior art, either alone or in any combination thereof.
To attain this, the present invention essentially comprises a pliable base connected to a pliable shell. An inflatable support rib is connected to the pliable shell, and a support frame is connected to the pliable shell. An inflatable mattress is connected to the pliable base.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated.
The invention may also include pliable screened windows and window covers, pliable doors and an attachment for an inflatable sofa. There are, of course, additional features of the invention that will be described hereinafter and which will form the subject matter of the claims attached.
Numerous objects, features and advantages of the present invention will be readily apparent to those of ordinary skill in the art upon a reading of the following detailed description of presently preferred, but nonetheless illustrative, embodiments of the present invention when taken in conjunction with the accompanying drawings. In this respect, before explaining the current embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of descriptions and should not be regarded as limiting.
As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present invention. It is important, therefore, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention.
It is therefore an object of the present invention to provide a new and improved inflatable tent that has all of the advantages of the prior art tents and none of the disadvantages.
It is another object of the present invention to provide a new and improved inflatable tent that may be easily and efficiently manufactured and marketed.
An even further object of the present invention is to provide a new and improved inflatable tent that has a low cost of manufacture with regard to both materials and labor, and which accordingly is then susceptible of low prices of sale to the consuming public, thereby making such inflatable tent economically available to the buying public.
Still another object of the present invention is to provide a new inflatable tent that provides in the apparatuses and methods of the prior art some of the advantages thereof, while simultaneously overcoming some of the disadvantages normally associated therewith.
Even still another object of the present invention is to provide an inflata
