With reference now to the drawing figures, wherein like reference numbers represent corresponding parts throughout the several views, FIGS. 1-8 show various aspects of example embodiments of a case 10 for housing an electronic device D. The case 10 generally comprises a back or base panel 20 and a peripheral sidewall or frame 60. In example forms, the base panel 20 and frame 60 are constructed of polycarbonate or other hard plastic, metal, composite, polymeric, ceramic and/or other material(s) of construction.

In the depicted embodiment, the base or back panel component 20 comprises a generally rectangular planar back 22 with rounded corners, configured to generally match the external geometry of a specified model of smart phone. In alternate embodiments, the shape and size of the case are configured to generally match the external geometry of other electronics devices, such as for example, tablet computers, smart phones, cell phones, MP3 players and other portable music and/or video players, electronic readers, handheld game devices, and the like. The back wall 22 optionally includes one or more openings or cutouts 24 for alignment with a camera, flash unit, controls, and/or other features of the electronics device to which the case 10 is configured for use.

As seen best in FIG. 2, the exterior face of the back 22 of the base panel 20 optionally has one or more decorative or protective materials applied thereto. In the depicted embodiment, the exterior face of the back 22 of the base panel 20 defines a recess into which a natural or simulated wood section is mounted in an ornamental design. In alternate embodiments, one or more sections of other materials such as other natural or simulated wood(s), stone(s), leather(s), metal(s) and/or other materials are applied to the exterior face of the back 22 of the base panel 20 in various combinations, colors, and/or designs.

As seen best in FIGS. 4-5, one or more upright attachment flanges 30 extend generally transversely from the interior face of the back 22 of the base panel 20, about the periphery of the base panel. The attachment flanges 30 include one or more male snap coupling elements 32 at positions along their outer surfaces, for interengagement with cooperating female snap coupling elements on the frame 60, as described below. The attachment flanges 30 optionally also define one or more opening(s) or cutout section(s) 34 for allowing access to controls, ports or other features of the electronic device D. In the depicted embodiment, the male snap coupling elements 32 comprise elongate linear ribs extending lengthwise along the outer surfaces of the attachment flanges 30, generally parallel to the plane of the back 22 of the base panel. Preferably, as shown in FIG. 5A, a portion of the male snap coupling elements 32 comprises a gradual reduction 33 wherein the rib extending along the outer surface of the flange 30 tapers into the flange 30 as the rib approaches the radiused portion of the flange 30, for example toward the bottom of the base panel. Preferably, the male snap coupling element 32 of the flange 30 generally opposite the rib having the gradual reduction 33 comprises a similar taper-like reduction. In example forms, the gradual reduction 33 of the male snap coupling elements 32 assists in assembly and disassembly of the case 10, allowing for easier connection and release of the case components.

In one example embodiment, the flanges 30 further comprise at least one first interengagement feature 36 for releasably interengaging at least one second interengagement feature 74 of the frame 60, as described below. In the depicted embodiment, the at least one interengagement feature 36 is formed with the flange 30 and comprises a channel or slot 38, defining a recessed or laterally offset fin or flange-like portion generally opposite the connected side of the flange 30. In one example form, four first interengagement features are provided along portions of the flanges 30 at spaced apart locations, for example wherein two features are positioned on each flange 30 that extends along the long sides of the case.

The interior face of the back 22 of the base panel 20 optionally defines a shallow recess 40 into which an internal liner 50 is mounted. The liner 50 optionally includes one or more openings or cutout sections 52 for alignment with a corresponding feature of the base panel 20, for example to provide clearance for access to or operation of a camera, control, port or other feature of the electronic device D. The liner 50 can comprise, for example, a sheet of PVC, silicone, rubber, soft plastic, foam, or other resilient material held in place on the base panel 20 by adhesive, to provide a measure of impact resistance.

As seen best in FIGS. 4 and 6, the peripheral sidewall or frame 60 comprises a generally rectangular body having a top panel 62, a bottom panel 64, and first and second side panels 66, 68, bounding front and back openings. One or more of the top, bottom and/or side panel(s) optionally define one or more openings or cutout portions 72 for allowing access to or use of controls, ports or other features of the electronic device D. Optionally, one or more buttons or actuator inserts 94 can be provided within the openings for interfacing with and operation of the controls, ports, or other features of the electronic device while at least partially housing or covering the same. In one example form, the inserts 94 releasably couple to the openings and permit at least some movement thereof while remaining releasably coupled thereto.

The frame 60 includes a front lip 82 projecting transversely inward into the front opening from the front peripheral edges of the top, bottom and side panels, such that the front opening does not permit the electronic device D to pass through when the case is installed on the device, and to provide protection to the front face of the electronic device.

The internal surfaces of one or more of the top panel 62, the bottom panel 64, and the first and second side panels 66, 68 of the frame 60 define one or more female snap coupling elements 92 for cooperative releasable engagement with the male snap coupling elements 32 of the base panel 20 when the case 10 is assembled. In the depicted embodiment, the female snap coupling elements 92 comprise elongate linear channels extending along the internal surfaces of the walls of the frame, generally parallel to the plane defined by the front lip 82. In alternate embodiments, the configuration and/or orientation of the male snap coupling elements 32 and the female snap coupling elements 92 may take other forms, such as pins and holes, projections and recesses, or other interengaging or abutting surface features; and/or the position of the male and female snap coupling elements can be reversed, with the male elements being on the frame 60 and the female elements being on the base 20.

In one example embodiment, at least one of the panels of the frame 60 further comprises at least one second interengagement feature 74 for releasably interengaging the at least one first interengagement feature 36 of the base 20. In the depicted embodiment, four second interengagement features 74 are provided along the panels of the frame 60, for example the first and second side panels 66, 68, for releasably interengaging the four first interengagement features 36 of the base 20 (see FIGS. 3 and 8). The second interengagement feature 74 generally comprises a fin or flange 76 that defines a channel-like slot, generally formed between the internal surface of the side panels 66, 68 and the flange 76. Thus, when the case 10 is assembled, the one or more male snap coupling elements 32 of the base 20 are releasably engaged with the female snap coupling elements 92 of the frame 60 and the at least one first interengagement feature 36 of the base 20 is releasably interengaged with the at least one second interengagement feature 74 of the frame 60. FIGS. 7-7B show greater details of the engagement of the snap coupling elements 32, 92 and interengagement features 36, 74. Taken along line 7A-7A of FIG. 7 and as shown in FIG. 7A, the snap coupling elements 32, 92 releasably couple together to restrain movement between the base 20 and the frame 60 in a first direction Dl. And taken along line 7B-7B and as shown in FIG. 7B, the first and second interengagement features 36, 74 releasably interengage to restrain movement between the side panels 66, 68 and the base 20 in a second direction D2, which is generally transverse to the first direction Dl. As depicted, the fin 76 of the second interengagement feature 74 is received within the slot 38 of the first interengagement feature 36 and the flange-like portion of the first interengagement feature 36 is received in the channel-like slot (formed between the internal surface of the side panels 66, 68 and the fin 76) of the second interangegement feature 74. Preferably, the first and second interengagement features 36, 74 act to stiffen the panels 66, 68, for example to act against the panels 66, 68 bowing inwards or outwards in the second direction D2. Thus, when the snap coupling elements 32, 92 and the first and second interengagement features 36, 74 releasably engage, the frame 60 acts as if it is more or less integral with the base 20, providing a strong and durable yet releasable connection therebetween. In alternate embodiments, the configuration and/or orientation of the first interengagement features 36 and the second interengagement features 74 may take other forms, such as pins and holes, projections and recesses, or other interengaging or abutting surface features; and/or the position of the first and second interengagement features can be reversed, with the first interengagement features being on the frame 60 and the second interengagement features being on the base 20.

As best seen in FIG. 8, one or more release access recesses or slots 84 are optionally provided along the interface between the frame 60 and the base 20 when assembled, to facilitate disassembly of the case 10 and removal or replacement of the electronic device D. In one example form, the slots 84 are generally positioned near the gradual reduction 33 of the male snap coupling elements 32 to provide for easier releasable disengagement of the base 20 from the frame 60, for example by a user inserting a fingernail or a tool into the slot and prying or pulling the frame apart from the base.

Thus configured, the case 10 of the present invention provides for secure attachment of a smart phone or other electronic device D therein, for example by placement of the phone into the frame 60 with the phone's screen side toward the front lip 82 of the frame, and the phone's controls aligned with the frame's cutouts 72. The base 20 is then installed over the back of the phone, and the attachment flanges 30 of the base inserted into the frame 60 internal of the top panel 62, the bottom panel 64, and the first and second side panels 66, 68 of the frame. The base 20 is pressed into the frame 60 until the male snap coupling elements 32 snap into the female snap coupling elements 92 and the at least one first interengagement feature 36 interengages the at least one second interengagement feature 74, to secure the case 10 in its assembled configuration, with the phone captured and retained between the base and the frame. The phone may then be utilized in standard fashion. To remove the case 10, the user inserts a fingernail or tool into the recess 84 between the base 20 and the frame 60 and separates the parts, allowing the phone to be removed from the case.
