The screen protector 16 includes a gasket 48, which may be a flexible, impermeable element. The mating elements 28 and the receiving elements 44 provide a clamping force therebetween such that, when assembled, the clamping force compresses the gasket 48 between a surface on the perimeter of the base 14 and a surface on the perimeter of the screen protector 16. According to some exemplary embodiments, the clamping force may vary based on an extent the mating elements 28 are assembled to the receiving elements 44 such that the clamping force increases as the mating elements 28 are further inserted into the receiving elements 44.
Now referring to FIG. 5, an exploded rear perspective view of the screen protector 16 is shown. The gasket 48 may be elastic and configured as a continuous loop. The gasket 48 may be disposed on a perimeter defined by the screen protector 16. The perimeter of the screen protector 16 includes a groove 50 defined by the rib 30 that is configured to retain the gasket 48 therein. According to some exemplary embodiments, the gasket 48 may be retained in the groove 50 at least in part by virtue of an elasticity of the gasket 48.

Each of the plurality of notches 32 is configured to receive a corresponding one of a plurality of retaining elements 42 of the screen protector 16 when the cover 12 is assembled to the base 14 and retains the screen protector 16 therebetween. Thus, when the cover 12 is assembled to the screen protector 16, the retaining elements 42 and the notches 32 form a male-female coupled pair. When the plurality of notches 32 receive the plurality of retaining elements 42, the lateral deformation of the cover 12 is reduced, thereby reducing a likelihood that one of the second securing elements 20 is inadvertently released from the first securing elements 18, and ensuring that a waterproof integrity of the case 10 is maintained.
Now referring to FIG. 15, an exploded rear perspective view of port plug gaskets 56 and a portion of the cover 12 is shown. The port plugs 36 may be sized to compress or provide a clamping force to a corresponding port plug gasket 56, when the port plugs are inserted in the ports 34 of the base 14, to form a water proof seal between the ports 34 and the port plugs 36. The port plug gaskets 56 may be elastic and configured as a continuous loop and disposed on a corresponding perimeter defined by each port plug 36.
Now referring to FIG. 16, a rear perspective view of a portion of the cover 12 is shown with the port plug gaskets 56 assembled to the port plugs 36. The port plugs 36a and 36b and their corresponding port plug gaskets 56a and 56b are shown as having rectangular and circular shapes, respectively.

Now referring to FIGS. 18 and 19, respective detail view D3 and detail view D4 are shown of the receiving element 44 of the base 14. The base 14 defines the receiving element 44 as a substantially rectangular opening that extends for a distance into a perimeter of the base 14. The receiving element 44 may extend for the distance along an axis A that is substantially perpendicular to an axis B that is substantially parallel to the planar portion of the base 14. The receiving element 42 may include a guide notch 58 that extends from the receiving element 44 toward the interior of the base 14 and provides for flexion or movement of the base 14 to provide impact absorption for the base 14. The perimeter of the base 14 defines a gasket surface 1 on the interior of the base 14 that receives the gasket 48 when the screen protector 16 is assembled to the base 14.
Now referring to FIG. 20, a view through section B-B of the screen protector 16 of FIG. 10 is shown. The mating element 28 is shown on side B of the screen protector 16 and opposite the retaining element 42 on side A of screen protector 16.
Now referring to FIG. 21, a detail view of section D5 in FIG. 20 is shown. The rib 30 of the screen protector 16 may protrude away from the screen protector 16, initially extending perpendicular to a planar portion of the screen protector 16 and then outward away from the medial portion of the screen protector 16 parallel to the planar portion of the screen protector 16, thereby defining the groove 50. The screen protector 16 defines a gasket surface 2 on the perimeter of the screen protector 16 that receives the gasket 48 when the gasket 48 is assembled in the groove 50. According to some exemplary embodiments, the plurality of mating elements 28 protrude along an axis C that is substantially perpendicular to the planar portion of the screen protector 16 and the axis D, which is substantially parallel to the planar portion of the screen protector 16. The retaining element 42 is on the side A of the screen protector 16 opposite the rib 30 and the mating elements 28, which are on side B of the screen protector 16.
Thus, embodiments of the present invention provide a robust case for a mobile device that not only provides impact protection but also remains waterproof during and after such impacts. The retaining elements 42 of the screen protector 16 advantageously couple to the notches 32 of the cover 12 when the cover is assembled to the base 14 with the screen protector therebetween. The cooperation of the retaining elements 42 and the notches 32 advantageously allows the second securing elements 20 of the cover 12 to remain securely attached to the first securing elements 18 of the base 14. The mating elements 28 and the receiving elements 44 further cooperate to advantageously provide a waterproof seal between the gasket surface of the screen protector and the gasket surface of the base 14 by applying a clamping force to compress the gasket 48 between the respective gasket surfaces. In this way, the cover 12, the screen protector 16 and the base 14 cooperate to provide a protective and waterproof mobile device case.
It will be appreciated by persons skilled in the art that the present invention is not limited to what has been particularly shown and described herein above. In addition, unless mention was made above to the contrary, it should be noted that all of the accompanying drawings are not to scale. A variety of modifications and variations are possible in light of the above teachings without departing from the scope and spirit of the invention.
