DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

A. Overview

(11) To gain a better understanding of the invention, a preferred embodiment will now be described in detail. Frequent reference will be made to the drawings. Reference numerals or letters will be used throughout to indicate certain parts or locations in the drawings. The same reference numerals or letters will be used to indicate the same parts and locations throughout the drawings, unless otherwise indicated.

B. Environment

(12) The present invention concerns the prevention of insect borne and small creature borne infectious diseases as noted above by providing an individual sized, sleeping bivy composed of an endoskeleton or frame overlaid and integrated with mosquito netting. Ideally the mosquito netting would meet CDC and WHO recommendations of pore size and would be treated with permethrin to prevent illness and death especially among children. This would allow air to pass through the shelter while still providing the desired high degree of bite protection. The endoskeleton is preferably, but not necessarily an inflatable structure or a self rising structure.

(13) The preferred embodiment now described will be with respect to an individual sized personal insect bite preventing shelter. The scale of the embodiment, therefore, is to be understood with respect to this type of article. It is to be understood as well, however, that the invention is applicable to other articles and its scale can vary accordingly.

C. Structure

(14) FIGS. 1-3 show a first embodiment of the present invention. The bivy 10 has a bottom or floor member 12 that is preferably water proof and can have a variety of forms. Preferably floor member 12 can be comprised of a plastic material, a coated plastic, a thermoplastic, a sheet of nylon, polyethylene, polypropylene, mylar, polyester, or other applicable or desired material. The material used in constructing floor member 12 can have a thickness ranging from about 10 to about 60 mil, with a preferred thickness of about 30-40 mil. The flooring material 12 is provided with an outer periphery defined by a series of interconnected structures 14-24 that collectively form an upstanding exterior or outer wall about the floor 12 that can have a height of 1 to 3 inches. The structures 14-24 can be connected to the flooring material by any one of a number of approaches including, but not limited to, glue or adhesive, by being heat welded, spot welded, or by other techniques including molding.

(15) The structures 14-24 that extend around floor member 12 could be constructed from a series of interconnected inflatable tubes, and an exterior inflating port 26 can be provided along one of the structures as is shown in the outer periphery section 14. Alternatively, the members 14-24 could be formed from tubes that have been filled with a self-inflating foam, or other memory retaining style or type of material provided therein, or from other forms of tubing, or a thickened wall material that will be equally collapsible into a small package.

(16) The bivy 10 also includes an upper endoskeleton or upper support structure 30 that is attached to floor member 12 by a suitable connection, for example glue/adhesive, sewing, by heat welding or like approaches. The upper endoskeleton or support structure 30 will be formed with two opposing end sections in the form of a three-dimensional pyramidal tripod or triframe 40 and 42. The foremost triframe 40 in FIG. 1 is comprised of a straight end most member 44 and a pair of straight side members 46 and 48. The opposite end's triframe 42 is LAO formed from a straight end most member 50 and its own pair of additional straight side members 52 and 54.

(17) The present design also allows the top or upper portion of each of the two opposing triframes 40/42 to form or develop a crimped area shown at 47 and 49 in the two opposing triframes 40/42, respectively, as is shown in FIG. 4. This could occur when or if the endoskeleton structure 30 is in an early stage of deflation, for example due to colder air that could cause the inflating air supply within bivy 10 to be reduced. The crimped areas 47/49 are formed from the collapsing of the upper portions of members 44/46/48 of triframes 40 and members 50/52/54 of triframes 42 where they meet with the opposing ends of the top horizontal support member 56. As the opposing crimped areas 47/40 form they will collectively serve to crimp the opposing ends of the top horizontal support member 56 and thereby hold air within the top horizontal support member 56 that will thereby assist in preventing the netting 70 from sagging and gaining a closer proximity to an occupant of the bivy 10.

(18) Extending between the triframes 40 and 42 is a straight horizontally extending top member 56, as shown in FIGS. 1-4, and a pair of additional straight horizontally extending side members 58 and 60 that are located on opposite sides of top member 56. Top member 56 extends between a top portion of each of the triframes 40/42 and will interconnect with the top ends of members 44-48 of triframe 40 and the top ends of members 50-54 of triframe 42 at the opposite end of bivy 10. Each of the side members 58/60 will span horizontally between to opposing legs of the triframe as is shown for side member 58 that spans between triframe members 46 and 52 while side member 60 spans between triframe members 48 and 54. The connection point between the side members 58/60 and the triframe members 48/54 and 46/52, respectively, is preferably located about one third the way down from the top of the length of the triframe members 48/54 and 46/52, respectively.

(19) The upper support structure or endoskeleton 30, that includes the two opposing triframes 40 and 42 and the horizontal members 56, 58 and 60, can be covered by insect or mosquito bite prevention netting or screening shown at 70 that can be made from a fabric comprised, for example, from a fabric such as a woven cotton, a woven plastic material made from, for example, polyethylene, polyester, polypropylene, a nylon material or other man made yarns, threads, or strands comprised of a combinations of fibers. A mesh size within the woven fabric netting 70 of 1.2 mm will be sufficient to stop mosquitoes from entering, and a smaller mesh size, for example 0.6 mm, will be small enough to stop other biting insects, such as biting midges and no-see-ums, from entering the screening. It should be understood that other mosquito screening materials could be used as well as what is important is to keep biting insects out of the bivy and away from biting contact with the bivy's occupant.

(20) While the screening or netting 70 allows airflow through the bivy, it is also possible to also overlay a tarp, a cover, or a water proof sheet to create climate protection as desired. One example would be to have a tarp or a type of water proof sheet or cover, as is shown in dotted line at 72, that could be rolled along the top horizontal member 56 to which it could be held in that rolled up manner by a tie, by a Velcro connected strap, or a similar device. When unrolled such a tarp or cover would extend over the upper endoskeleton 30 including the two end triframes 40/42.

(21) The size of the bivy 10 reasonably would conform to standard humanitarian aid and military, manufactured, cot and commercial or naval berth dimensions. As an example, the width of bivy 10 can vary between about 40 and about 55 inches, and preferably between about 24 and 36 inches, while the over all length of bivy 10 can vary from about 5.5 to about 7 feet and preferably can be about 87 inches long. The height of bivy 10, from floor member 12 to the top support 56 can range from about 20 to about 30 inches, and preferably is about 25 inches in over all interior height.

(22) FIGS. 1-3 also show, for example, that the mosquito netting or screening can be provided with an entry portal 74 on one or both sides of bivy 10. That portal can be arranged in the form of an elongated U-shaped, two way entry zipper, positioned on a side of the bivy and for example below horizontal member 58 and above the floor 12. Preferably the zipper portal 74 should be able to be opened and closed from both the inside and outside so that the occupant can control entry and exit. It should be understood that other forms of entry portals 74 could also be used, for example, a Velcro closure, snaps, or other similar mechanisms.

(23) The upwardly extending wall members 14-24, that define the outer periphery of floor 12, as well as each of the upper support structures comprised of members 44-60 can all be part of an inflatable structure or system formed from suitable hollow tubing. Each tubing cross point or interconnection, as for example at the apex of each of the triframes where members 44, 46 and 48 join one another, and where each triframe element joins the upwardly extending walls forming the outer periphery of floor 12, will comprise a joint or interconnection that fluidly interconnects each tube within the inflatable system. In a like manner the horizontal members 56, 58 and 60 will also fluidly interconnect with the triframes 40 and 42, with the top member 56 joining the apex of the opposing triframes, and with the side members 58 and 60 joining triframe members 46/52 and 48/54, respectively.

(24) The individual tubes forming the straight members 44-60, as well as the tubes forming the upstanding walls 14-24 that extend around floor member 12, could be tubes having a diameter that might vary from about 2 inches to about 5 inches, with the preferred diameter being about 3 inches. Also, it is desirable to be able to deflate the bivy 10 and collapse the entire structure into a package that will have size and weight about equal to that of a football. Consequently, the collapsed package should weigh between 14-25 oz. with a preferred weight of about 1 pound (16 oz.).

(25) As noted above there is an exterior inflation port 26 through which the entire endoskeleton 30 and the upstanding walls 14-24 can be inflated as a collective group. If the bivy is used where night air can be cold the inflated volume might partially deflate. To permit an occupant within bivy 10 to top up the inflation air volume, or to inflate or reinflate the inflatable system (members 14-60), an interior inflation port 80 can be provided, for example on the inside of triframe member 46 as is shown in FIGS. 5 and 6. Port 80 is preferably comprised of a pouch 82, a pull out tube 84 having a closure 86 at the end thereof to close off the outer end of tube 84. The bivy occupant can simply pull out tube 84 from pouch 82, remove or open the end closure 86 and blow into tube 84 to re-inflate or add supportive inflation into the inflatable system by mouth without exiting the bivy and exposing the occupant to bites. Additionally, a pump could be used with both the interior and exterior inflation ports 26/80.

(26) Another exemplary alternative to inflating the endoskeleton or upper support 30 comprised of individual inflatable tube members 14-60, would be as shown in FIG. 7 where those tubes filled with a resilient, self inflating open cell foam 90 as shown by the portion of tube 44 that has been cut away. The foam could, for example, be polyurethane or plasticized polyvinylchloride foam, that will fill with air through an open inflation port 26. The outer tube, which can comprise an envelope for the foam, can be, for example, a coated nylon with a wall thickness that can vary between 0.0015 and 0.025 inches, a tube diameter that can vary between 2-6 inches, and the open cell foam can have a density that can vary between 0.5 and 5 pounds per cubic foot, and can be provided with an internal air pressure of from 3 to 20 psi via inflation port 26. The endoskeleton or upper support structure 30 and the upstanding walls 14-24 can all be compressed with air inflation port 26 being an open condition so that the foam filled tubes will be reduced in size and the while bivy can be collapsed into a small package that might be slightly heavier than that involving only the air inflatable tube system discussed previously.

(27) As another alternative, shown in FIG. 8, is achieved by having each of the members 14-60 in comprising the supporting and collapsible endoskeleton structure formed from an interconnected network of smaller diameter tubes 92, instead of the inflatable tubes of the previous embodiment of FIGS. 1-4. The tubes 92 will preferably have a thickened sidewall 94, as shown, for example whose thickness can be about one quarter to about one third of the total diameter, and with an overall tube 92 diameter of about 1 to 1.8 inches. When collapsed each of the tubes 92 will be bent and upon releasing the collapsed package the tubes 92 will each spring into a relatively straight condition and be strong enough to reform the endoskeleton and hold up the netting 70 and to remain in an erected condition until once again collapsed back into a small package.

(28) As is evident from FIGS. 1-3 the triframes 40/42 at each end of the bivy 10 are formed from three straight members that define acute angles within the two triangles within each triframe 40/42. Looking at triframe 40, it is preferred that the uppermost angle between end member 44 and member 46 be about 30 , and that the angle at the bottom each of those members have with the outer periphery member 14 could then be 75 . Other angle combinations could, for example, include a top angle that could range between 30 and 50 with the bottom angles then both ranging between 75 and 65 . In general, as the top angle decreases the height increases, and the height would decrease as the top angle was enlarged, making the relationships inverse. It should be understood that other angles would be used as well with the foregoing range being the preferred range.

(29) A further embodiment is shown in FIG. 9 that is also comprised of inflatable tubular members. Here the foremost triframe 112 includes side members 106 and 108 and an end member 110. This embodiment differs from the first embodiment by having the horizontal side members 100 and 102 extend beyond the sides of the triframe ends 106 and 108 on triframe 112 and interconnect with the end member 110 of triframe 112 by extension members 114 and 116. This same arrangement will also be provided at the opposite end triframe 120. That opposite end triframe 120 is itself comprised of side members 122 and 126 and an end member 124. The two extensions of horizontal side members 10 and 102 are shown at 128 and 130, respectively.

(30) The bottom sheet 160 will be attached to and surrounded by edge members 140-150 that are also fluidly interconnected with triframes 112 and 120, and the horizontal side members 100, 102, 118 and extension members 114/116 and 28/130.

(31) Thus, the horizontal side members 100/102 will effectively extend fully around the sides and each triframe and will be fluidly interconnected with the other inflatable tubes forming the upper endoskeleton support structure supporting netting material 152. Triframes 112 and 120 are interconnected by the horizontal side members 100/102 and by a top horizontal member 118. An inflating port 170 is also provided within an internal inflator pouch 172 like that shown in FIGS. 4 and 5. Also, a waterproof tarp shown in doted line at 174 could be provided as well.

D. Operation

(32) To erect the bivy it can be unrolled or opened up from its collapsed condition. For the embodiment using the inflatable system, once the inflation port 26 is exposed the inflation system comprised of members 14-60 can be inflated into the form shown in FIG. 1. The mosquito netting or screening is adhered to the endoskeleton of the bivy so the inflation of that endoskeleton will automatically expand and arrange the netting and the entry port 72. To collapse an erected bivy 10 port 26 can be opened, along with port 86, and the bivy can be folded or rolled into a small package as the air is expelled from within the inflation system.

(33) Where the endoskeleton tubing is filled with the self inflation open celled foam, once the collapsed package is opened and the inflation port 26, or port 86 as well, is opened the self rising foam will fill causing the endoskeleton to rise into its desired shape. It may be helpful to provide some additional air pressure by adding air into or through port 26 or 86. To collapse this embodiment the ports 26/86 can be opened and the bivy can once again be compressed, rolled or folded into a smaller package size with entrained air once again being expelled through ports 26/86 as the bivy is compressed into its smaller package size.

(34) In the smaller tube version, the raised bivy can be folded, compressed or rolled into its smaller size with the tubes being bent and thus confined within the collapsed structure.

(35) In each instance, the smaller collapsed structure and shape can be retained by an outer cover, by a tie, a snap, by a Velcro strap system, or any other approach that will securely yet releasably hold the bivy elements in their compressed, folded, rolled or collapsed form.

(36) When introducing elements of various aspects of the present invention or embodiments thereof, the articles a, an, the and said are intended to mean that there are one or more of the elements, unless stated otherwise. The terms comprising, including and having, and their derivatives, are intended to be open-ended terms that specify the presence of the stated features, elements, components, groups, and/or steps, but do not exclude the presence of other unstated features, elements, components, groups, and/or steps and mean that there may be additional features, elements, components, groups, and/or steps other than those listed. Moreover, the use of top and bottom, front and rear, above, and below and variations thereof and other terms of orientation are made for convenience, but does not require any particular orientation of the components. The terms of degree such as substantially, about and approximate, and any derivatives, as used herein mean a reasonable amount of deviation of the modified term such that the end result is not significantly changed. For example, these terms can be construed as including a deviation of at least +/5% of the modified term if this deviation would not negate the meaning of the word it modifies.

(37) While the invention has been described in connection with what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention is not to be limited to the disclosed embodiments, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
