Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to tents and more particularly pertains to a new tent with integral air mattress for improving camping comfort.




2. Description of the Prior Art




The use of tents is known in the prior art. More specifically, tents heretofore devised and utilized are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements.




Known prior art includes U.S. Pat. No. 4,335,545; U.S. Pat. No. 4,000,585; U.S. Pat. No. 4,819,389; U.S. Pat. No. 4,928,442; U.S. Pat. Des. 330,745; and U.S. Pat. Des. 285,880.




While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new tent with integral air mattress. The inventive device 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. The bottom surface of the bottom layer includes a series of intersecting grooves for permitting air flow and water flow underneath the tent. The shell is attached to a skirt member which extends from the base member. The air mattress does not cover the entire top surface of the bottom layer, so that a portion of the bottom layer adjacent a door of the tent is exposed, forming a flat area suitable for placing shoes and other gear thereon.




The invention further includes a tent structure having a support frame comprised of a plurality of support poles made of a series of telescoping pole elements. A locking means is provided to lock the pole elements in an extended position. The locking means comprises a tongue and groove arrangement which are engaged/disengaged through twisting movements of the pole elements. A central hub element is provided which receives the ends of the support poles and locks them in place using locking springs.




In these respects, the tent with integral air mattress according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of improving camping comfort.




SUMMARY OF THE INVENTION

DESCRIPTION OF THE PREFERRED EMBODIMENT




With reference now to the drawings, and in particular to

FIGS. 1 through 10

thereof, a new tent with integral air mattress embodying the principles and concepts of the present invention and generally designated by the reference numeral


10


will be described.




As best illustrated in

FIGS. 1 through 10

, the tent with integral air mattress


10


comprises a base member


12


supported upon the ground, a support frame


13


extending upwardly from the base member, and a shell


14


attached to the base member and supported by the frame


13


.




The base member


12


, as best illustrated in

FIGS. 1

,


2


A-B, and


3


, is composed of a bottom layer


15


of a water resistant material, such as rubber, or the like. The layer


15


rests directly upon the ground and therefore it has a pre-selected thickness for cushioning and insulating the base member


12


. The bottom surface


16


of the layer


15


includes a series of intersecting grooves


17




a, b


formed therein for permitting air and water to pass underneath the base member when it rests on the ground. The bottom surface


16


is also suitably roughened to prevent slippage of the base member upon the ground. Skirts


18


of the same material as the layer


15


extend upwards from the top surface of the layer


15


, the purpose of which will become apparent later in the description.




The base member


12


also includes a pair of air mattresses


19




a


,


19




b


fixedly attached to the top surface of the bottom layer


15


using any suitable means. The air mattresses


19




a


,


19




b


are preferably made of a material capable of holding air and are covered in a soft material for improving the comfort of the mattresses. Such materials are generally known in the art and therefore no further discussion of them is needed. The mattresses


19




a


,


19




b


are generally identical, so only one will be described in detail, it being understood that the other one is similar.




The mattress


19




a


defines an enclosed chamber which is separate and distinct from the chamber defined by the mattress


19




b


. An air inlet port


20


of conventional configuration communicates with the chamber, permitting air to be input into the chamber, but preventing air escape. In addition, a separate air outlet port


21


communicates with the chamber for permitting rapid deflation of the mattress


19




a


. As shown in

FIG. 9

, the air outlet port


21


comprises an outlet nozzle


22


integral with the mattress and having a threaded end which engages with an internally threaded cap


23


for closing the nozzle


22


and preventing escape of air. The nozzle


22


is configured such that when the cap is removed, it allows air to freely exit the chamber of the mattress, such that the mattress can be rapidly deflated.




As illustrated, the mattresses


19




a


,


19




b


are disposed substantially side by side upon the layer


15


, and have a thickness such that the skirts


18


extend upward above the top of the mattresses. However, the mattresses do not completely cover the entire top surface of the layer


15


such that a lowered area


24


is formed at the ends of the mattresses. The lowered area


24


thus comprises the portion of the layer


15


which is not covered by the mattresses. The lowered area


24


forms a suitable location for shoes and other equipment to be placed before climbing up on the mattresses. The shoes and equipment placed in the area


24


are kept from direct contact with the ground by the layer


15


, thus keeping such items dry.




The support frame


13


comprises four flexible, telescoping support poles


25




a


,


25




b


,


25




c


,


25




d


which each extend upward from a respective corner of the base member


12


and are connected thereto by being disposed within connectors


26


disposed at each corner of the base member. The opposite ends of the poles


25




a


,


25




b


,


25




c


,


25




d


are connected to a central hub element


27


. Turning to

FIG. 5

, one of the telescoping support poles


25




a


is shown, it being understood that the remaining poles


25




b-d


are identical to the pole


25




a


. The pole


25




a


is composed of a series of telescoping pole elements


28




a


,


28




b . . . n


with the element


28




a


having a larger diameter than the element


28




b


which has a larger diameter than the next element, and so on. The support poles


25




a-d


can be comprised of any number of individual pole elements


28




a


,


28




b . . . n


. The elements


28




a


are adapted to fit within the connectors


26


. The pole elements are thus able to be retracted into the largest pole element


28




a


, similar to an antenna, and extended out for use. A means for locking the pole elements in the extended position must therefore be provided. Such a means is illustrated in

FIG. 6

, where two of the pole elements


28




a


,


28




b


are shown. The interior wall of the element


28




a


includes a pair of circumferentially spaced shoulder assemblies


29




a


,


29




b


formed thereon, with the assemblies being separated by gaps


30




a


,


30




b


. Each shoulder assembly


29




a


,


29




b


comprises a pair of axially spaced shoulders


31




a


,


31




b


defining a groove


51


therebetween. The pole element


28




b


includes at one end thereof a pair of projecting tongues


52


on diametrically opposite sides thereof. The tongues


52


are sized for fitting through the respective gaps


30




a


,


30




b


, so as to permit the pole element


28




b


to be telescoped into the pole element


28




a


. The pole element


28




b


is axially locked relative to the element


28




a


by axially aligning the tongues with the grooves


51


and rotating the elements relative to each other, so that the tongues are disposed within the grooves thus preventing axial movement of the element


28




b


relative to the element


28




a


. It should be understood that each of the pole elements includes a pair of projecting tongues at one end and a pair of shoulder assemblies on its interior at the other end, except for the two end pole elements


28




a


,


28




n


. The pole element


28




n


includes only the projecting tongues. Thus each of the pole elements is locked in a similar fashion to the connection between the elements


28




a


,


28




b


. As can be seen in FIGS.


5


and


7


-


9


, the distal end of each support pole (i.e. pole elements


28




n


) includes a neck region


53


followed by a bulbous tip


54


, the purpose of which will become apparent later in the description. It is preferable that the pole elements


28




a


,


28




b . . . n


be made of a graphite material such that it is able to be flexed into an arched configuration.




The central hub element


27


, which receives the ends of the support poles


25




a


-


25




d


, comprises a solid, cross shaped member having four arms


55




a


-


55




d


, with each arm having an aperture


56


formed therein. Disposed within each aperture


56


is a locking spring


57


which is configured to matingly receive the neck region


53


and bulbous end


54


of the support poles, to secure the distal ends of the poles within the hub element


27


. The distal ends of the poles are thus frictionally retained within the apertures


56


by frictional engagement with the springs


57


. The ends can be removed from the hub by a simple pulling force applied to the pole element


28




n.






The shell


14


is supported by the support poles


25




a-d


so as to define a tent interior area. The shell


14


is comprised of a series of nylon panels connected to each other to define the walls of the tent


10


. The base of the shell


14


is affixed to the skirts


18


such as by stitching and/or gluing, in order to form a watertight connection between the shell and the base member


12


. Therefore the shell


14


is permanently attached to the base member


12


. The shell


14


includes a plurality of spaced, nylon sleeves


32


attached thereto, such as by stitching, through which extend the poles


25




a-d


for supporting the shell.




One of the panels of the shell


14


includes a door means


33


formed therein. The door means


33


comprises a pair of outer flaps


34




a


,


34




b


which preferably are a part of the shell


14


. The flaps


34




a


,


34




b


are integral at one edge thereof with the shell


14


, while the remaining edges are removably secured by zippers, as is conventional. The door means


33


also includes an inner mesh screen composed of separate mesh flaps


35




a


,


35




b


appropriately affixed to the inside of the shell


14


as is also conventional. The mesh screen permits fresh air to enter the interior of the tent when the flaps are moved out of the way, while keeping out bugs.




As best shown in

FIG. 4

, the tent


10


includes a door mat means


36


which can be rolled onto the ground in front of the door means


33


. The door mat means


36


comprises a flexible sheet material which is integrally connected along one edge thereof to the base member


12


. The sheet is preferably rolled-up when not in use, as illustrated in

FIG. 1

, for storage within the tent. To use, the door means is opened, allowing the sheet to be unrolled in front of the area of the door means.




The side of the shell


14


opposite the door means


33


includes a mesh screen window


37


therein, so as to permit fresh air flow into the tent. The shell


14


also includes a donut shaped, mesh screen sun roof


38


adjacent the top thereof for further increasing air flow and sunlight into the tent. A central fabric area


39


encloses the hub element


27


and is suitably attached to the mesh sun roof


38


so as to secure the fabric area and the hub element to the tent


10


. The central fabric area


39


comprises a fabric layer above and below the central hub element


27


and stitched together so as to secure the hub element between the layers. Apertures are provided between the layers, aligned with the holes


56


, in order to allow passage of the pole elements


28




n


so that they can be inserted into the hub element. Preferably, means are provided within the tent so as to permit selective covering and uncovering of the window


37


and the sun roof


38


. The mesh flaps


35




a


,


35




b


, mesh window


37


, and mesh sun roof


38


are preferably formed of a UV resistant mesh material to protect the occupants of the tent from the harmful effects of UV rays from sunlight.





FIG. 10

illustrates a carrying bag


40


which can be used to carry the tent


10


when it is not assembled. The bag


40


defines an interior volume for holding the base member and shell, and includes an exterior sleeve


41


for holding the telescoping poles


25




a


-


25




d


. The bag also includes a pocket


42


for holding miscellaneous items such as a mattress repair kit. A pair of adjustable, locking straps


43


,


44


are used to close the bag. The bag can also include a conventional zipper connection


45


for gaining access to the interior of the bag. In order to provide for easy carrying of the bag, a pair of handles


46


,


47


are attached thereto, and can be secured together using a conventional strap member


48
