DETAILED DESCRIPTION OF THE INVENTION

FIGS. 1 6 illustrate the preferred embodiment of the apparatus or IPNVG protective case of the present invention by the numeral 10. As illustrated, particularly in the figures, apparatus or protective case 10 comprises a first container portion 12 having a somewhat non-oblong configuration, which is designed not to include sharp corners or the like, as illustrated in FIG. 1, but specifically configured to house a pair of IPNVG therein. Container portion 12 provides an outer hard protective shell 14 having a continuous side wall 16 and a base or floor portion 18, as is seen in FIG. 5. Preferably the exterior hard shell 14 would be constructed of a heavy duty nylon material combined with a special parachute thread for defining the durable outer case capable of protecting an IPNVG 20, of the type as illustrated in FIG. 3. Further as illustrated in FIGS. 2 and 4, the protective case 10 would further define a top portion or cover 22 also having a heavy duty nylon outer shell 24 with a wall 26 and an upper portion 28. The top portion 22, as seen in FIG. 4, would include a carrying handle 23, which is secured to the outer surface 25 of top portion 22, at each end 27 of handle 23, defining a space 29 for grasping handle 23.

As is further illustrated in the figures, the container portion 12 and the top portion 22 are connected along a common edge 30 which allows the top to move between open and closed positions, in the direction of arrow 33, to serve its protective function. There is also provided a zipper 32 along the entire disengagable edge between top portion 22 and container portion 12. Zipper 32 would be either be one continuous zipper or a pair of zippers so that when the zipper 32 is zipped closed, it defines the closed protective case 10 as is illustrated in FIG. 4.

Returning now to FIGS. 1 and 2, within the interior of the protective shell 14, there is included a soft, compressible material 40. This protective material comprises a high quality soft, optical foam 42 which defines a soft protective cushion for the IPNVG 20 that would be placed therein, as seen in FIG. 3. The soft material 40 would include a pair of carved out portions 44 and 46 with a protective cushion wall 48 there between, as seen in cross-section in FIG. 2. These carved out portions 44 and 46 would define the openings which would house the IPNVG 20 when the IPNVG 20 is placed therein, as illustrated in FIG. 3. The protective wall 48 would simply serve as a means for allowing the two central body portions 21 of the IPNVG to be protected therein when being stored away as illustrated in FIG. 3.

Further, as illustrated, the top portion 22 would likewise contain the protective foam 42 and would include a carved away central portion 50, as seen in FIG. 2, so that when the top portion 22 is closed upon the container portion 12, the uppermost member 54 of goggles 20 would rest therein for protection when the case 10 is in the closed position.

As further illustrated in FIGS. 1 2, there is also included a plurality of openings 60, which would in the preferred embodiment would include four openings 60, each of which would have the ability to accommodate a battery therein, so that the night vision goggles 20, as stored in container 12, could include an extra set of batteries so as to provide a greater level of protection, should the batteries within the goggles 20 lose power.

Returning to FIG. 4, there is illustrated the protective case 10 in the closed position, with the zippers 32 having been fully closed in this particular view. As illustrated in FIG. 4, in the preferred embodiment, there would be a set of the IPNVG goggles 20 within the case 10 when the case is closed, after the goggles 20 are set therein as being done in FIG. 3. The handle 23, as discussed earlier, would allow the case 10 to be easily carried around and placed into the cockpit of a plane and stored therein until used. Further, as seen in FIG. 4, the case 10 would include a second handle 45, similar to the handle 23 on the top portion 22 of case 10, but handle 45 placed on the front portion 13 of the case 10, in the same manner as handle 23, for allowing carrying of the case 10 in this fashion.

It should be made clear that it is the combination of the rigid exterior 14 and the interior soft compressible optic foam material 42, having the carved out portions 44 and 46 in the lower material 42, and the carved out portion 50 in the top foam material 42 which allows the IPNVG goggles 20 to be stored within a very soft environment that would prevent damage to the goggles; yet have a protective exterior outer shell 14 which would protect the IPNVG goggles 20 from exterior trauma during flight within the cockpit.

Finally, FIGS. 1 through 6 illustrate the preferred embodiment, in terms of dimensions and construction, of the present invention, for providing protection for the IPNVG goggles, including the preferred thickness of the interior optic foam 42 and the depth of the cut out spaces 44,46 within the optic foam 42 in which the goggles 20 would rest. Although the dimensions are preferred, it is foreseen that various dimensions may apply in various cases, depending on the type of goggles that have been stored and the change in the shape and size of the goggles during the course of the improvement of the art.

In the preferred embodiment, the thread utilized would be Nylon, Size E, 8 oz., with a tensile strength of 8.5 lbs., or equivalents of these specifications. Although the weave size may vary depending on various factors, the fabric, in the preferred embodiment would be Cordura Nylon 1000 Denier coated one side for waterproof finish. The Nylon webbing would be Type 17, 1 inch wide, with a tensile strength of 2500 lbs, in the preferred embodiment. These specifications cited above may be changed to equivalent specifications depending on certain factors.
