The front face 110 includes a transparent screen window 180 that is configured to overlie the touchscreen of the smart phone 200 when the smart phone 200 is positioned within a pocket 190 formed between the transparent screen window 180 and a base panel 300 (best illustrated in FIGS. 1C and 2B) that forms the back face 120 of the case 100. The base panel 300 includes a pocket opening 301 that extends through the base panel 300 into the pocket 190 and is dimensioned to allow the portable electronic device 200 to pass into and out of the pocket 190. The transparent screen window 180 may further include an aperture 181 configured to overlie the fingerprint scanner 220 when the device is positioned within the pocket 190. The base panel 300 may also include one or more apertures or openings 302 that extend into the pocket 190 that may serve to facilitate functionality of the portable electronic device 200.
As best illustrated in FIGS. 2A and 2B, the case 100 is comprised of a multi-layered structure that includes the base panel 300 that extends from the first end section 130 to the second end section 140, a front panel 310 bonded to a mesh substrate 320 that extends from the second end section 140 to the mid-section 150, a transparent polymer layer 330 that forms the transparent screen window 180 and adjacent regions 338 thereto, and a plurality of LED light sources 401, 402, 403, 404, 405, 406 mounted on flexible printed circuit board and electrically connected via a cable 430 to a battery 410 contained within a housing 420 having a removable battery access cover 421 on one side and a button 422 on the opposite side. As best illustrated in FIG. 10 the cable 430 may be connected to the battery housing 420 via a strain relief component 440 interposed there-between.
In addition to the pocket opening 301 described above, the base panel 300 (as well as the overlying layers) also includes openings for each of the two rings 170, which in the present embodiment are defined by polymer D-ring structures 171, and a battery access opening 303, which is covered by a back cover 340 that is connected to the back panel 300 and movable from a closed position to an open position as best illustrated in FIG. 11. When the back cover 340 is in the closed position, the back cover 340 overlies the battery access opening 303 in the arm band to the battery housing 420. In the open position the back cover 340 is displaced from the battery access opening 303, relative to its position in the closed position, to allow access to the battery housing 420 and the removable battery access cover 421 so that the user can access the battery 410 contained therein. The battery housing may be made of plastic. The base panel 300 and back cover 340 may be formed of synthetic polymer such as neoprene or SBR coated spandex, or other suitable material.
The front panel 310 includes a front side and an opposing underside with the underside being bonded to the mesh substrate layer 320. The front panel 310 further includes a pattern of slots 311 extending there-through that reveal the underlying mesh substrate 320. The patterns of slots 311 and the thicknesses are best illustrated in FIGS. 1A-1B, 2A, 3, 4A and the cross-sectional views depicted in FIGS. 2B, and 4B-4D. Notably, the thickness of the front panel 310 (between the front side and the underside of the front panel) is not uniform bur rather may include one or more faded regions that thin-out the front panel 300 as it extends along its slots outward from the pocket 190 toward the perimeter edges of the case 100, which may facilitate dispersion of light so as to more desirably illuminate the case 100. The front panel may be made of a polymer, such as poured polyurethane (PU).
As best illustrated in FIGS. 7 and 5, the transparent polymer layer 330, which is located over the base panel 300 and under the front panel and mesh substrate 310, 320, may further include etching that creates a texture on the surface of the adjacent regions next to the transparent screen window 180 of the transparent polymer layer 330. The etching is configured to correspond with the slotted patterns 311 on the front panel. The transparent polymer layer 330 may be formed of thermo plastic polyurethane (TPU) that can meet anti-fog standards at 60 degrees temperature, 95% humidity for a period of 72 hours.
The electrical assembly components (e.g., LEDs, battery housing) are positioned within corresponding apertures 331-337 disposed on the transparent polymer layer 330 (best depicted in FIGS. 6 and 7) so that they are housed between the front panel 310 and mesh substrate 320 on the front side of the case 100 and the base panel 300 on the back side of the case 100. The base panel 300, front panel 310, mesh substrate 320, the transparent polymer layer 330 are attached to each other via stitching 500 (best depicted in FIGS. 1A and 1B) such that the electrical components reside in compartments defined by the stitched layers. When the LEDs 401-406 are positioned within the apertures of the transparent polymer layer 330 and powered light is emitted sideways away from the pocket 190 and into the adjacent regions of the transparent polymer layer, which in turn may serve to create a light pipe effect. The combination of the slotted regions and the fading thickness of the front panel 310 together with the light pipe effect of the transparent polymer layer 330 serves to allow light emitted by the internally positioned LEDs to illuminate the front face 110 of the case 100.
