INFI,ATABLE STRUCTURE FOR COVERING SPORT UTILITY VEHICLES, BOATS
AND THE LIKE
Field of the Invention This invention relates to the field of inflatable structures including tents, and in particular to an inflatable structure useful as an event venue, portable temporary shelter, or for covering from the elements mid-to-large sized vehicles including sport utility vehicles, boats, cars and the like.
Back~rc)und of the Invention Inflatable tents for use in camping are known in the prior art and are sold commercially by for example Airzone Recreation Products of Kelowna, British Columbia, Canada. Such tents typically replicate camping tents available commercially which rely on bent fibreglass poles for their support structure and instead substitute inflatable poles which, when bent, provide the supporting framework for the exterior fabric skin or canopy of the tent over which a so-called fly sheet may be mounted. In the other extreme, large tents are known in the prior art for use such as by the military for providing field barracks, field hospitals and various depot facilities, such tents often being made of canvas and supported on tubular metal-pole supporting structures.
Applicant believes that a commercial need exists for relatively large pneumatically inflatable tent-like structures which are larger than conventional recreational camping tents and smaller than military-style field tents. It is believed that such structures will find commercial acceptaince and use by the owners of large for example sport utility vehicles, boats, trailers, and other wl:ieeled vehicles or towables which ordinarily would require a large garage or shed for their safe storage and which are often not housed in, for example, conventional residential homes as not having extended garage facilities. Also applicant believes that commercial acceptance and use of , ., If .
such larger pneumatically inflatable tent-like structures may include those in the field of portable corporate sponsorship pavilions for example for use in trade-shows, portable pneumatically inflatable recreational and professional sports shelters for sheltering equipment, non-engaged players, or sickly or wounded players on for example the side-lines of a sports field.
What is required, and is an object of the present invention to provide, is a relatively larger pneumatically inflatable structure which may be readily transportable in that, when collapsed, the structure is not exceedingly heavy or overly bulky so the structure may be transported in for example the aforementioned sport utility vehicles, in mini-vans, or in the beds of pickup trucks and the like, and for example may be camed by two adult males to a convenient location for their use, and wherein the structure may be erected using for example a high volume, low pressure air compressor running for example from the twelve volt power source of the vehicle used to transport the collapsed structure.

Detailed Description of Embodiments of the Invention As seen in the accompanying Figures 1-4 wherein similar characters of reference denote corresponding parts in each view, the pneumatically inflatable structure according to one aspect of the present invention includes two adjacent pairs of bowed and criss-crossed pneumatic tubes 1:2 and 14 mounted to a base 16 so as to sandwich a vertically upstanding bowed vault-forming pneumatic tube 18 therebetween. In one embodiment of the invention, pairs of tubes 12 and 14 are substantially identical and are mounted adjacent one another separated only by the diameter of the ends 18a and 18b of tube 18.
In particular, a pair of tubes 12 may include tubes 20 and 22 criss-crossed at a vertex 24. They are mounted at vertex 24 in fluid communication with one another by a cooperating hollow flexible conduit 26. The ends 20a and 22a of tubes 20 and 22 respectively are mounted on a common side 16a of base 16 for example by the use of flexible folded tabs 27 formed at the end of each of the tubes. The opposite ends of tubes 20 and 22, namely ends 20b and 22b respectively are mounted by tabs 27 to a common edge 16b of base 16 opposite to edge 16a. T'he opposite ends 18a and 18b of tube 18 are mounted adjacent ends 20a and 22b .,,I~
respectively on a first side of tube 18, and are mounted adjacent ends 28a and 30b respectively on the opposite immediately adjacent side of tube 18. Thus ends 28a and 30b of tubes 28 and 30 respectively which form the criss-crossed pair of tubes of pair 14, are also mounted to edges 16a and 161) of base 16 respectively. The opposite ends of tubes 28 and 30 namely ends 28b and 30a are moiunted to the corners of base 16, on the corners adjacent end edge 16d.
Ends 22a and 20b are mo unted on the corners of base 16 adjacent end edge 16c.
Each of the pairs of tubes 12 and 14 are bowed and criss-crossed so as to form a frame defining a downwardly concave substantially domed enclosure 32 and 34 respectively.
Vault-fbrming bowed pneumatic tube 18 is bowed so as to be also downwardly concave defining an opening underneath tube 18 which is at least as big in its lateral and height dimensions as the corresponding dimensions of domed enclosures 32 and 34. Thus taken in combination the two adjacent pairs of tubes 12 and 14 and the vault-forming tube 18 define an elongate open enclosure elongate along longitudinal axis A. That is, the elongate open enclosure includes the two domed enclosures 32 and 34 and an inter-connected vaulted passageway 36 extending therebetween.
For an efficient and modular use of more conventional components such as the tents taught in my United States Patent No. 6,263,617 and incorporated herein by reference, in one aspect of the present invention two such inflatable tents are used to form pairs of tubes 12 and 14, each being mounted on common base 16. Base 16 may be a rectangular flexible sheet. Where pairs of tubes 12 and 14 are employed modularly and each already has a floor mounted to the ends of the pairs of tubes, in a further embodiment of the present invention, a separate spanning, joining or linking section of base 16 is employed to join the adjacent sides of the conventional tent floors and so as to sandwich therebetween vault-forming tube 18 mounted with its ends on the connecting piece of base 16. As may be understood then, it is not necessary that the inflatable structure according to the present invention merely and only is limited to two pairs of tubes 12 and 14 and a single vault-forming tube 18 as it will be understood that a further elongated enclosure may be constructed using three or more pairs of criss-crossed bowed inflatable tubes similar to , ..~~
pairs 12 or 14, and wherein adjacent pairs of tubes each have bowed vault-forming tubes such as tube 18 interleaved therebetween.
In a preferred embodiment, each of the tubes of the criss-crossed pairs of tubes 12 and 14 and vault-forming tube 18 is of a design such as taught in my United States Patent No.
6,263,617 such that a resilient or at least flexible inner tube is mounted within an outer flexible relatively non-resilient sleeve, and wherein such a sleeve has a folded seam along its interior circumference folded over so that the sleeve and inner tube may be constructed as a linear pole which rnay then be bent to accommodate the required bowed shaped to form the domed structures.
It has been found that such inflatable tubes for example having approximately a five inch diameter which is constant along the length of each tube may be inflated to approximately ten pounds per square inch (psi) and thereby provide sufficient rigidity for an inflatable structure which may then house vvheeled vehicles or towable trailers such as the trailer and boat combination illustrated in Figure 1 which is not intended to be limiting.
Thus in one embodiment, the height from base 16 to the vertex of vault-forming pole 18 may be approximately eight feet and the distance between the opposite ends of the pole are approximately thirteen feet, vault-forming tube thus being approximately twenty-four-twenty-six feet long depending on the desired curvature and amount of bow.
The vault-forming pneumatic tube 18 in one embodiment not intended to be limiting is approximately twenty-four feet long and has a substantially constant circumference along its length of approximately twenty-two inches. In that embodiment the distance between opposite ends 18a and 18b of vault-forming pneumatic tube 18 measured across base 16, that is from edge 16a to edge 16b, is approximately thirteen feet. Advantageously, the elongate open enclosure may be approximately twenty feet long using tubes 20, 22, 28 and 30 each having a length of also approximately twenty-four feet and a circumference of approximately twenty-two If inches. In this embodiment of the structure the height of the elongate open enclosure under the vault-forming pneumatic tube may be approximately eight feet.
An array of interconnected tubes 3 8 stemming from a common manifold 40 maybe used to simultaneously inflate all of the tubes, where for example separate air lines 38 are mounted in fluid communication with adjacent ends of tubes 18, 20 and 28, and a single source (note shown) of pressurized air is mounted to manifold 40.
As will be apparent to those skilled in the art in the light of the foregoing disclosure, many alterations and modifications are possible in the practice of this invention without: departing from the spirit or scope thereof. Accordingly, the scope of the invention is to be construed in accordance with the substance defined by the following claims.
Figure 4 is the view of the inflatable structure of Figure 1 with the boat and trailer removed.
Figure 5 is the view of the inflatable structure of Figure 3 with the structure shown in dotted outline and a canopy mounted on the structure.
Figure 6 is the view of Figure 5 showing the canopy alone.
Detailed Description of Embodiments of the Invention As seen in the accompanying Figures 1-4 wherein similar characters of reference denote corresponding parts in each view, the pneumatically inflatable structure according to one aspect of the present invention includes two adjacent pairs of bowed and criss-crossed pneumatic tubes 1:2 and 14 mounted to a base 16 so as to sandwich a vertically upstanding bowed vault-forming pneumatic tube 18 therebetween. In one embodiment of the invention, pairs of tubes 12 and 14 are substantially identical and are mounted adjacent one another separated only by the diameter of the ends 18a and 18b of tube 18.
In particular, a pair of tubes 12 may include tubes 20 and 22 criss-crossed at a vertex 24. They are mounted at vertex 24 in fluid communication with one another by a cooperating hollow flexible conduit 26. The ends 20a and 22a of tubes 20 and 22 respectively are mounted on a common side 16a of base 16 for example by the use of flexible folded tabs 27 formed at the end of each of the tubes. The opposite ends of tubes 20 and 22, namely ends 20b and 22b respectively are mounted by tabs 27 to a common edge 16b of base 16 opposite to edge 16a. T'he opposite ends 18a and 18b of tube 18 are mounted adjacent ends 20a and 22b .,,I~
respectively on a first side of tube 18, and are mounted adjacent ends 28a and 30b respectively on the opposite immediately adjacent side of tube 18. Thus ends 28a and 30b of tubes 28 and 30 respectively which form the criss-crossed pair of tubes of pair 14, are also mounted to edges 16a and 161) of base 16 respectively. The opposite ends of tubes 28 and 30 namely ends 28b and 30a are moiunted to the corners of base 16, on the corners adjacent end edge 16d.
Ends 22a and 20b are mo unted on the corners of base 16 adjacent end edge 16c.
Each of the pairs of tubes 12 and 14 are bowed and criss-crossed so as to form a frame defining a downwardly concave substantially domed enclosure 32 and 34 respectively.
Vault-fbrming bowed pneumatic tube 18 is bowed so as to be also downwardly concave defining an opening underneath tube 18 which is at least as big in its lateral and height dimensions as the corresponding dimensions of domed enclosures 32 and 34. Thus taken in combination the two adjacent pairs of tubes 12 and 14 and the vault-forming tube 18 define an elongate open enclosure elongate along longitudinal axis A. That is, the elongate open enclosure includes the two domed enclosures 32 and 34 and an inter-connected vaulted passageway 36 extending therebetween.
For an efficient and modular use of more conventional components such as the tents taught in my United States Patent No. 6,263,617 and incorporated herein by reference, in one aspect of the present invention two such inflatable tents are used to form pairs of tubes 12 and 14, each being mounted on common base 16. Base 16 may be a rectangular flexible sheet. Where pairs of tubes 12 and 14 are employed modularly and each already has a floor mounted to the ends of the pairs of tubes, in a further embodiment of the present invention, a separate spanning, joining or linking section of base 16 is employed to join the adjacent sides of the conventional tent floors and so as to sandwich therebetween vault-forming tube 18 mounted with its ends on the connecting piece of base 16. As may be understood then, it is not necessary that the inflatable structure according to the present invention merely and only is limited to two pairs of tubes 12 and 14 and a single vault-forming tube 18 as it will be understood that a further elongated enclosure may be constructed using three or more pairs of criss-crossed bowed inflatable tubes similar to , ..~~
pairs 12 or 14, and wherein adjacent pairs of tubes each have bowed vault-forming tubes such as tube 18 interleaved therebetween.
In a preferred embodiment, each of the tubes of the criss-crossed pairs of tubes 12 and 14 and vault-forming tube 18 is of a design such as taught in my United States Patent No.
6,263,617 such that a resilient or at least flexible inner tube is mounted within an outer flexible relatively non-resilient sleeve, and wherein such a sleeve has a folded seam along its interior circumference folded over so that the sleeve and inner tube may be constructed as a linear pole which rnay then be bent to accommodate the required bowed shaped to form the domed structures.
It has been found that such inflatable tubes for example having approximately a five inch diameter which is constant along the length of each tube may be inflated to approximately ten pounds per square inch (psi) and thereby provide sufficient rigidity for an inflatable structure which may then house vvheeled vehicles or towable trailers such as the trailer and boat combination illustrated in Figure 1 which is not intended to be limiting.
Thus in one embodiment, the height from base 16 to the vertex of vault-forming pole 18 may be approximately eight feet and the distance between the opposite ends of the pole are approximately thirteen feet, vault-forming tube thus being approximately twenty-four-twenty-six feet long depending on the desired curvature and amount of bow.
The vault-forming pneumatic tube 18 in one embodiment not intended to be limiting is approximately twenty-four feet long and has a substantially constant circumference along its length of approximately twenty-two inches. In that embodiment the distance between opposite ends 18a and 18b of vault-forming pneumatic tube 18 measured across base 16, that is from edge 16a to edge 16b, is approximately thirteen feet. Advantageously, the elongate open enclosure may be approximately twenty feet long using tubes 20, 22, 28 and 30 each having a length of also approximately twenty-four feet and a circumference of approximately twenty-two If inches. In this embodiment of the structure the height of the elongate open enclosure under the vault-forming pneumatic tube may be approximately eight feet.
An array of interconnected tubes 3 8 stemming from a common manifold 40 maybe used to simultaneously inflate all of the tubes, where for example separate air lines 38 are mounted in fluid communication with adjacent ends of tubes 18, 20 and 28, and a single source (note shown) of pressurized air is mounted to manifold 40.
As will be apparent to those skilled in the art in the light of the foregoing disclosure, many alterations and modifications are possible in the practice of this invention without: departing from the spirit or scope thereof. Accordingly, the scope of the invention is to be construed in accordance with the substance defined by the following claims.
