Abstract:
A protective case for a mobile device having a co-molded multi-layered construction having a first layer that generally forms the external back face surface of the case. A second layer generally forms the perimeter bumper of the case. The first layer is comprised of material that has a hardness and/or rigidity that is greater than the second layer. The layers are configured to interact with one another so that they are capable of distributing impact forces to mitigate damage to the mobile device. One or more reinforcing support members in the form of a beam or rod are provided and extend internally and longitudinally near the sides of the case and preferably near the long sides of a rectangular shaped case. The reinforcing support members are formed of even harder or more rigid materials, such as metal alloy or cured fiber reinforced composite rods or beams, relative to the first and second layer and are capable of providing additional support and rigidity to the mobile device to stop or mitigate unintentional or undesired bending of the mobile device.

     BACKGROUND OF THE INVENTION 
     Field of the Invention 
       [0002]    This patent document relates to user removable protective enclosures or cases for mobile electronic devices and more particularly to such cases that have a reinforcing support member. 
       Description of the Related Art 
       [0003]    Mobile consumer electronic products, such as smart and cellular phones, computing tablets, MP3/audio/video players, gaming devices and laptops are continuously and rapidly evolving to meet expanding consumer demands. Typically, such devices include an external enclosure or encasing that house the electronics of the device and an interactive touchscreen on one or more faces of the device. With each passing day, such devices are becoming more and more powerful, connected, and interactive; employ bigger and bigger screens and better and more numerous cameras; and now run what is seemingly countless specific applications and features that address any conceivable need. Indeed, they are becoming so commonplace in today&#39;s society that it is now hard to remember life without them. 
         [0004]    Manufacturers, while racing to provide such enhanced functionality, are also increasingly very sensitive to increases in the overall weight and bulkiness of their devices. As a result they are decreasing the thickness to offset increases in screen size. For example, the most recent generation of iPhone 6 Plus, introduced in September 2014, is just over half the thickness of the original iPhone (1 st  generation) introduced in 2007, yet provides approximately double the screen space. As a result, these devices, which are commonly encased within metallic housings, are becoming more and more susceptible to undesirable or unintentional bending, which can impair the functionality of the screen and buttons, and/or expose or damage the electronics within the device. 
         [0005]    The inventors here have recognized, therefore, that there is a need to develop protective cases for such mobile electronic devices that are capable of providing additional reinforcing support to mitigate or prevent bending of the device while minimizing bulkiness and weight and yet maintain a high level of protection. 
       SUMMARY OF THE INVENTION 
       [0006]    Disclosed are numerous aspects of a unique and inventive protective case configured to receive, retain and protect a mobile device that includes a front face and a back face that define the height or thickness of the mobile device, a perimeter defined by top-end, bottom-end, right, and left sides residing between the front and back faces, and corners defined at the intersecting regions of the sides. The case may be for a mobile electronic device that is in the form of a tablet, a mobile phone, an MP3 audio player, a gaming device, or other portable handheld electronic device and may have one or more touchscreens on its front face and/or back face. 
         [0007]    The protective case is, in a first aspect, comprised of three primary components, a bottom shell portion, an upper portion, and one or more reinforcing support members. The bottom shell portion is dimensioned and configured to reside below the back side or face of the electronic device. The upper portion generally extends from the bottom shell portion and is dimensioned and configured to cover at least a portion of one or more sides and/or a portion or a perimeter portion of the front face of the mobile device. In an illustrated implementation, the one or more reinforcing support members are housed or otherwise located and retained within the bottom shell portion. 
         [0008]    The bottom shell portion may be co-molded with the upper portion as respective first and second layers, wherein the bottom shell portion layer may be made of a material that is more rigid than the co-molded upper portion layer. The bottom shell portion may be formed, for example, of a polycarbonate (PC) material while the upper portion layer may be formed of less rigid thermoplastic urethane (TPU), a thermoplastic elastomer (TPE), an acrylonitrile butadiene styrene (ABS), nylon, silicone rubber or a combination thereof. Additional layers may also be co-molded or otherwise incorporated into the protective case. 
         [0009]    The reinforcing support member may be formed of a third material that is different from either the material that forms the bottom shell portion or the material that forms the upper portions and may provide additional support and rigidity to the mobile device via the protective case. It is contemplated, for example, that the reinforcing support member may be formed of metal or metal alloy such as a steel, stainless steel, tungsten, titanium or magnesium alloy and/or may be formed of a composite (hardened or cured) fiber reinforced structure or lay-up of directionally oriented fibers and/or non-directionally oriented (e.g., randomly oriented) fibers with or without an internal core component or substrate. The reinforcing support members may be circular, oval, square or rectangular in cross-section or a combination thereof and may be uniform in size and shape or may vary in size and shape from one region to another of the support member. 
         [0010]    The one or more reinforcing support members may be co-molded with the bottom shell and/or upper portions and/or may be inserted after molding within a cavity formed within the components. The reinforcing support members, in another aspect, may be formed of a material that is more rigid and/or may be a greater bending stiffness than the material that forms either the bottom shell portion or the upper portion of the case. 
         [0011]    The reinforcing support members may be constructed uniformly along its longitudinal length or may be constructed with greater or lesser rigidity along its length by increasing its dimensions and/or by virtue of selection of construction materials at a particular longitudinal region. For example, the reinforcing support member may be formed more rigidly near the regions that are configured to be positioned adjacent the buttons of the electronic device (e.g., volume buttons) by, for example, increasing the dimensions of the reinforcing support member in those adjacent residing regions. 
         [0012]    In one aspect, the protective case may be manufactured by placing the reinforcing support members (e.g., steel rods) in a mold configured to define the shape of the bottom shell portion. The reinforcing support members may run the full length or the majority of the length of the case and/or the electronic device that the case is configured to receive. The reinforcing support members may be positioned within the case so as to be configured to run lengthwise near or under the longitudinally extending edges of the electronic device so as to extend between the top and the bottom ends or sides of the device and/or case on the right and/or left sides thereof. 
         [0013]    Multiple reinforcing support members may be employed and each may be formed of the same and/or different materials and may be positioned along or under the left and/or right sides of the electronic device or positioned more centrally and inwardly from the side walls. Once the reinforcing members are positioned in the desired location in the mold, the mold can be injected with a first polymer material (e.g. PC) on top of the reinforcing support members to form the bottom shell portion containing there within the reinforcing support members to form a first molded construct. The first molded construct is then inserted into another mold that is configured to form the upper portion of the case. Once the first molded construct is positioned in the second mold, the second mold is injected with a second more pliable polymer material (e.g. TPU) that is co-molded to the first molded construct and the first polymer material. 
         [0014]    The one or more reinforcing support members may be housed within the bottom shell portion base section of the wall structure (e.g., reference numeral  220 , best seen in  FIG. 4 ) without increasing the thickness of the wall. Alternatively, as illustrated in the drawings, the bottom shell portion (e.g., reference numeral  300 , also best seen in  FIG. 4 ) may be configured to include one or more outwardly extending protrusions (e.g., reference numeral  360  in the drawings) that house the one or more reinforcing support members. The outwardly extending protrusions may be configured to extend lengthwise along the backside of the case and protrude outwardly in a direction away from the back face of the electronic device so as to create ridges, footings or rails (e.g., reference  362 , best illustrated in  FIGS. 1C-1D  and  FIG. 5B ) on the backside of the case that are capable of elevating the electronic device above a resting surface, which may further protect the electronic device from accidental spills by elevating it from the surface upon which the case is resting. The outward protrusions may be configured include apertures that allow visibility to the reinforcing member(s) housed therein. In this way the user may be able to visibly detect whether the reinforcing member is fractured or stressed or whether it remains sound operating condition. 
         [0015]    The outwardly extending protrusions on the back side of the bottom shell may be constructed with multiple reinforcing support members of the same or different configurations and constructed with the same or different materials. Alternatively, the outwardly extending protrusions may be constructed without the incorporation of any reinforcing support member. In the later construction, the outward protrusions extending lengthwise on the backside of the bottom shell portion may provide additional support and rigidity to the mobile device via the protective case. 
         [0016]    It should be understood that each of the foregoing and various aspects, together with those set forth in the claims and summarized above or otherwise disclosed herein, including the drawings, may be combined to form claims for a device, apparatus, system, method of manufacture, and/or use without limitation.

       DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0025]    As summarized above and illustrated in the drawings, disclosed herein are various aspects of a protective case for a mobile device capable of providing additional reinforcing support to mitigate or prevent bending of the device while minimizing bulkiness and weight, yet maintaining a high level of protection. Aspects of which are summarized above and illustrated in the drawings. 
         [0026]    Commonly disclosed in  FIGS. 1-6  is a protective enclosure or case  200  for a mobile device (not shown) that illustrate, by way of example only, various of the configuration and construction aspects of the case. In this particular implementation, the case is configured for an Apple iPhone 6 plus® mobile or smart phone device. It should be understood, however, that the case may be configured for any mobile device or electronic device, including but not limited to portable or cellular phones, PDAs, MP3 or audio/video devices, gaming devices, laptop computers or computing tablet devices. The case  200  is generally comprised of a multilayered construction comprising layers  300 ,  500  of relatively different rigidity, and one or more reinforcing support members  400  extending there-through and being formed of an even more rigid material. 
         [0027]    As best depicted in  FIGS. 1A-1F , the protective case  200  includes front and back face walls  210 ,  220  and left-side and right-side walls  230 ,  240  and top-side and bottom-side walls  250 ,  260 , respectively. The side walls  230 ,  240 ,  250 ,  260  reside between the front and back faces. Each of the walls  210 ,  220 ,  230 ,  240 ,  250 ,  260  are dimensioned to correspond in dimension to the front and back faces, and left, right, top and bottom sides of a mobile device, respectively. In the illustrated embodiment, the case  200  is generally rectangular in shape extending longitudinally from the bottom to the top side walls  260 ,  250  with the left and right sides  230 ,  240  being the opposing long sides and the top and bottom sides  250 ,  260  being the opposing short sides of the rectangle 
         [0028]    More specifically, the front face wall  210  is defined by inner and outer surfaces  211 ,  212  and includes an inwardly projecting retention lip or rim  214  (best illustrated in the cross-sectional views of  FIG. 4 ). The retention rim  214  is positioned to reside over the perimeter region of the front face of the mobile device to assist in retaining the mobile device within the case  200 . The retention rim  214  may encircle a portion or the entire perimeter of the front face of the mobile device. For example the retention rim  214  may be configured to extend at regions of the top, bottom, left and/or right sides of the mobile device in any combination thereof. The back face wall  220  is also defined by inner and outer surfaces  221  and  222  and may include a camera lens and flash opening or aperture  224  extending there-through. 
         [0029]    The left side and right side walls  230 ,  240  are also each defined by inner and outer surfaces  231 ,  232  and  241 ,  242 , respectively. The left side wall  230  may further include volume control buttons  234 , which like the other buttons described herein, are positioned, dimensioned, configured and adapted to being depressed by the user so as to interface and actuate the volume control buttons on the mobile device, yet revert back to the undepressed position when the user removes pressure from the button. Also included in the left side wall  230  can be an opening or aperture  236  that is positioned and dimensioned to correspond with the ringer silent switch of the mobile device to provide functional user access to the switch. The right side wall  240  may include a power button  243  that is positioned, dimensioned, configured and adapted to interface with the power button on the mobile device. It is contemplated that any of the side walls may include additional apertures and/or buttons to provide access or control over corresponding ports or buttons on the mobile device should the device have such controls or ports on that side. 
         [0030]    The top side and bottom side walls  250 ,  260  are also each defined by inner and outer surfaces  251 ,  252  and  261 ,  262  respectively. The top side wall  250  may include (although not depicted) a mobile device button positioned, dimensioned, configured, and adapted to interface with a corresponding button on the mobile device. The buttons on the case may reside within and be connected to an aperture in a levered manner at one end or at a mid-section of the aperture, such that when pressed, the button hinges around the lever connection. The bottom side wall  260  may include aperture  264  positioned and dimensioned to correspond with the speaker grill regions on the mobile device. The bottom side wall  260  may further include a headphone jack/microphone and data/charging port apertures  266 ,  267  that are positioned and dimensioned to correspond with the headphone jack port and microphone opening and the data and charging port, respectively. Collectively the side walls  230 ,  240 ,  250 ,  260  define a perimeter  270  between the front and back faces  210 ,  220  of the protective case  200 . 
         [0031]    As previously noted, the case  200  may be formed of a multilayered construction that includes two layers  300 ,  500  that are co-molded together to form a unitary integral construct. Various aspects of these layers and their inter-relationship, construction and manufacture are described in more detail. 
         [0032]    As best illustrated in  FIGS. 3A-3C , the first layer  300 , which forms the lower or bottom shell portion, is defined by first inner and outer surfaces  310 ,  311 , respectively, and dimensioned to cover the back face of the mobile device. The first layer  300  is configured to extend to the perimeter of the mobile device at the back face boundary, which is the perimeter defined by the intersection of the side walls and the back face of the mobile device. 
         [0033]    The first layer  300  may further include a plurality of upward extending protrusions  330  positioned along the perimeter region of the first layer  300  to correspond in location with the corners and certain portions of the side regions of the mobile device. The upward extending protrusions  330  are dimensioned to reside at a height that is slightly below the height of the mobile device at those regions. However, it is contemplated that one, some or all of the upward extending protrusions  330  may be configured to extend at, below, or above the height of the mobile device in any combination. 
         [0034]    The first layer  300  or bottom shell portion may be configured to cover the entire, a majority, half or less than half of the back face of the mobile device and may be configured to extend to or around the entire, a majority, half or less than half of the perimeter of the mobile device at the back face boundary. 
         [0035]    In the illustrated implementation, the first layer  300  is configured to cover nearly the entire back face of the mobile device, with the exception of the flash and camera lens window aperture  224  and the entire perimeter of the back face. It should be understood, however, that alternative configurations may be employed. Perimeter regions in the first layer  300  that reside between one or more of the corners may be removed. Mid-section regions of the layer  300  may be removed to allow for access to, or user utilization of, user controls, additional touchscreen interface, and/or other device features (e.g., speakers, cameras, lights, microphone, etc.) that are located on the side walls and/or back face of the mobile device. 
         [0036]    The first layer  300  may further include one or more outwardly and rearwardly extending protrusions  360 . The outwardly extending protrusions  360  are configured to extend longitudinally along opposing sides lengthwise on the backside of the case outwardly away from the backside of the electronic device housed therein. Each of the outwardly extending protrusions  360  may include one or more retention cavities  370  that extend longitudinally with the length of the outwardly extending protrusion  360 . Each of the cavities  370  is dimensioned to receive and house a reinforcing support member  400 . The outwardly extending protrusions may also include one or more windows or apertures  380  that allow the reinforcing member to be visual seen by the user to facilitate visual detection as to whether a reinforcing member is fractured or stressed or to confirm that it remains undamaged and in sound condition. 
         [0037]      FIGS. 5A-5B  are front and back face end perspective views, respectively, of another embodiment of the protective case for a mobile device that further illustrate the construction of the protective case and the relationship of the first layer, second layer and reinforcing support members. As shown in  FIG. 5A , the front face of the protective case includes cavities  370  (see also  FIGS. 3B-3C ) to reveal the reinforcing support member  400 . In another embodiment, no cavity is formed in the front face of the protective case, however, the first layer  300  may be made of a transparent or semi-transparent material to reveal the reinforcing support member  400  (formed of a darker or distinctly colored material residing there beneath). 
         [0038]      FIG. 6  is front face view of one embodiment of the protective case  200  for a mobile device. As shown in  FIG. 6 , the front face of the protective case may include tabs  580  extending from the second layer  500  along the left and right side walls and overlaying a portion of the inner surface  310  of the first layer  300  to provide additional support. Although each of the tabs  580  are shown as a continuous piece on each side, it is also contemplated that a break or breaks may be applied to each of the tabs so that each side can have multiple tabs. The tabs  580  may have apertures  590  sized to receive elevated protrusion members  390  extending from the inner surface  310  of the first layer  300  to form interlocking mechanism. 
         [0039]    The reinforcing support member  400  may be made of any suitable material or combination of materials. It is contemplated, for example, that the one or more reinforcing support members may be formed of metal or metal alloy such as a steel, stainless steel, tungsten, titanium or magnesium alloy and/or may be formed of a composite fiber reinforced structure or lay-up of directionally oriented fibers and/or non-directionally oriented (e.g., randomly oriented) fibers with or without an internal core component or substrate. The reinforcing support members may circular, oval, square or rectangular in cross-section. The purpose of the reinforcing support member  400  is to provide additional support and rigidity to the phone via the protective case  200 . 
         [0040]    The second layer  500 , which forms the upper portion, is also defined by inner and outer surfaces  510 ,  511 , respectively. The second layer  500  is generally more flexible and is dimensioned to cover the top, bottom, right and/or left sides of the mobile device and forms the inwardly projecting lip or rim  214  of the front face wall  210  that serves to extend over the perimeter of the front face of the mobile device so as to assist in retaining the device within the case  200 . 
         [0041]    While in the illustrated embodiment, the second layer  500  extends around the entire perimeter of the mobile device, it may be configured elsewise. Thus, it is contemplated that the second layer  500  may cover the entire, a majority, half or less than half of the top, bottom, right and/or left sides of the mobile device and/or may be configured to extend around less than the entire, a majority, half or less than half of the perimeter of the mobile device in any combination. The second layer  500  includes the one or more mobile device control apertures that extend through the layer and/or control buttons (e.g.,  234 ,  236 ,  243 ,  264 ,  266 ,  267 ) that are dimensioned and positioned to allow access to and/or control to the control buttons and/or ports (e.g., power button, volume button, ringer silent switch, headphone jack, microphone opening, speaker grill, and data/charging port) on the mobile device. The second layer  500  may also further include one or more overlapping indentations  540  in the inner surface  510  at regions configured to reside at portions of the sides and corners of the mobile device. The indentations  540  are configured or molded so as to be in the negative image of the upward extending protrusions. 
         [0042]    While, the first and second layers  300 ,  500  may be co-molded to form an integrated construction, it should be understood that it is contemplated that only portions of one or more of the layers may be co-molded, or each of the layers may be separately formed and mechanically attached to one another by clips, snaps or latches between each of the components or between for example the third layer and the first layer. A combination of co-molding and mechanical attachment of the layers or portions thereof may also be employed. 
         [0043]    In a fully integrated or co-molded construction, the case  200  would be properly dimensioned and have sufficient flexibility to allow the user to insert and remove the mobile device without damaging to the case  200  or the device. The flexibility may be implemented via the construction materials employed (e.g., having a relatively softer more pliable upper shell portion and more rigid bottom shell portion to allow the device to be inserted into the window defined by the upper shell) and the configuration of the layers or components. 
         [0044]    When the components are modular or separable from one another, the user may wrap the second layer around the mobile device and then clip the first layer into position onto the second layer and around the device, or vice versa (e.g., position the device into the first layer and clip the second layer into the first layer around the device). The clips, snaps, hooks, or other mechanical attachments may be formed or molded into: (a) two or more of the layers at their perimeter regions, (b) one or more of the upwardly extending protrusions  330  and/or indentions  540  in the first and second layers  300 ,  500 , (c) the control buttons  234  and corresponding apertures on the first and second layers  300 ,  500  and/or (d) at any region where two layers are in contact or in proximity to one another. Thus, a combination of co-molding and/or mechanical attachment of the layers may be employed. 
         [0045]    The materials that form the layers may be selected based on their hardness or rigidity. For example, the first layer  300  may be made of a first material that has a first hardness or rigidity, and the second layer  500  (including the tabs  580 ) may be made of a second material that has a second hardness or rigidity that is different from the first hardness. In a preferred implementation, the first hardness is greater than the second hardness and the first rigidity is greater than the second rigidity. 
         [0046]    The first and second layers  300 ,  500  may be formed of a composition comprised of one or more materials including but not limited to polycarbonate; thermoplastic urethane (TPU), thermoplastic elastomer (TPE), acrylonitrile butadiene styrene (ABS), nylon, metal, silicone rubber, or any combination thereof. For example, the first layer  300 , which is the harder and more rigid of the two layers, may be formed of a composition comprised of polycarbonate (PC), a combination of polycarbonate and ABS, nylon, fiber reinforced plastic, and/or metal. The second layer  500 , which is the relatively less rigid, softer layer, may be formed, for example, of a composition comprised of TPU and/or TPE or combination thereof or other polymer or suitable material. 
         [0047]    In a preferred implementation, the first layer  300  may have a Shore A durometer hardness that is 50% or more greater than the second layer  500 , 40% or more greater than the second layer  500 , 30% or more greater than the second layer, 20% or more greater than the second layer, or 10% or more greater than the second layer all +/−5% as measured using the American Society for Testing and Materials (ASTM) standard D2240. The first layer may have a Shore A durometer hardness of 100+/−15, 100+/−10, or 100+/−5, or 100 as measured using the American Society for Testing and Materials (ASTM) standard D2240. The second layer may have a Shore A durometer hardness of 65+/−15, 65+/−10, 65+/−10, or 65 as measured using the American Society for Testing and Materials (ASTM) standard D2240. It should be understood that the two layers may be formed of materials having a Shore A hardness that is comprised of any combination of hardness described above. Thus, for example the first layer may be formed of a material having a Shore A durometer hardness that is 100+/−5 while the second layer may be formed of a different material having a shore A durometer hardness of 65+/−15. 
         [0048]    Each of the one or more reinforcing support members  400  may be preferably formed of a material that is even more rigid and harder than the material that forms either the first layer/bottom shell portion  300  or the second layer/upper portion  500 . It is also preferable that the support members  400  be relatively small, for example for the iPhone 6 Plus case as illustrated, preferably 3 mm and/or less in cross-sectional width, height or diameter to avoid adding bulk, and even more preferably 2.5 mm or less in cross-sectional width, height, and/or diameter, and yet even more preferably 2 mm or less in cross-sectional width, height, and/or diameter, and yet even more preferably 1.5 mm and/or less in cross-sectional width, height, and/or diameter, and yet even more preferably 1.0 mm and/or less in cross-sectional width, height, or diameter. The cross-section being understood to be taken at a plane cutting transversely at a right angle to the longest axis of the member  400 . 
         [0049]    A method of manufacturing the protective case  200  for a mobile device is also disclosed. The case may be manufactured by placing the reinforcing support members  400  (e.g., steel rod) in a mold configured to define the shape of the bottom shell portion  300 . The reinforcing support members  300  are dimensioned and positioned in the desired manner relative to the configuration of the bottom shell portion  300 . For example, they may be dimensioned and positioned to run lengthwise near or under the longitudinally extending edges of the electronic device so as to extend between the top to the bottom sides or ends of the device and/or case on the right and/or left sides thereof. Multiple reinforcing support members may employed that are formed of the same and/or different materials (which may be harder or more rigid than one or more of the other members  400  employed in the case  200 ) and may be positioned along or under the left and/or right sides of the electronic device or positioned more centrally and inwardly from the left and right side walls  230  and  240 , respectively. 
         [0050]    Thus, it is contemplated, for example, that multiple reinforcing support members  400  may be employed and that those members may be formed of materials that have the same, or different hardness and rigidity. Staggering or stepping the hardness or rigidity or other material properties of multiple reinforcing support members  400  incorporated into the case, allows flexibility in the manner the case  200  performs under stress to resist bending. Thus, for example, the user could inadvertently stress the electronic device (e.g., by sitting on it or jamming it into a brief case), the force could fracture or visibly strain one (e.g., the more rigid member) of reinforcing support members  400  but may be insufficient to visibly strain or fracture another support member  400  (e.g., the less rigid member). The electronic device could therefore continue to be afforded reinforcement and protection, yet the user would be warned by virtue of the visible fracture or strain on the deformed reinforcing support member that undue stress has been applied to the device and can therefore take corrective measures to avoid damaging the device. 
         [0051]    Similarly, the use of materials having different physical properties may provide additional advantages. For example, a metal rod may be employed to form one of the support members and a more rigid polymer (or fiber reinforced polymer) may be employed to form another of the support members having a greater bending stiffness than the member formed of the metal rod. The case  200  could, therefore, be capable of providing strong resistance to bending forces via the more rigidly formed support member(s), yet the one or more malleable metal rods that form the other support members  400  may continue to provide support even when those more rigid members fracture or fail under excessive stress. Additionally, the user could bend the metal rods, to the extent deformed, back into alignment, even though the more rigid polymer members have been fractured. The case thereby may continue to provide the device added reinforcement support. 
         [0052]    While the illustrated embodiment depicts two support members  400  extending on opposing sides of the case along the left and right long sides of the case  200 , it should be understood that the case  200  may employ fewer or more support members and that one or more such support members may be oriented diagonally or perpendicularly to the long-side of the case. Such diagonally and/or perpendicularly oriented support members may be in addition to those oriented lengthwise as depicted or may be employed instead of one or more of the lengthwise oriented support members. 
         [0053]    Once the one or more reinforcing members  400  are positioned in the desired location in the mold, the mold is injected with a first polymer material (e.g. PC) on top of the reinforcing support members  400  to form a first molded construct in the form the bottom shell portion  300  and the reinforcing support members  400  contained or housed therein. The first molded construct is then inserted into another mold compartment that is configured to form the upper portion  500  of the case  200 . Once the first molded construct is positioned in the second mold, the second mold is injected with a second more pliable polymer material (e.g. TPU) that is co-molded to the first molded construct and the first polymer material to thereby form second molded construct, which in the illustrated embodiment would be the case  200 . 
         [0054]    While the illustrated embodiment is described as being formed of two co-molded layers, it should be understood that additional layers may be molded to form the case and that any of the molded constructs could be incorporated into another molded or unmolded component such as a wallet or folio. In addition, while the illustrated embodiment is described as incorporating reinforcing support members in the bottom portion of the shell  300 , it should be understood that the reinforcing support members may be incorporated into the upper shell portion  500  along one or more of the side walls or along overlapping regions of the upper and lower shell portions and that incorporating such reinforcing support members into the supper shell portion  500  may be in addition or as a substitute to those in the lower shell portion  300 . To the extent reinforcing support members are incorporated into the upper shell portion  500 , those members may be positioned in the mold in the desired location when the upper portion  500  is molded. The upper portion  500  could be molded before or after the lower portion  300 , and then the two portions being co-molded together to form an integral case construct. 
         [0055]    When reinforcing support members  400  are incorporated into the upper portion  500 , such members may be incorporated into one, two, three or all four sidewalls  230 ,  240 ,  250 ,  260  lengthwise along a portion or the entirety of the sidewalls and/or into the front face wall  210 . The reinforcing support members  400 , for example, may be incorporated to run lengthwise along the base of any, some or all of the sidewalls, and/or may run lengthwise along the mid or upper region of those sidewalls nearer the front face wall  210 . When such members  400  are incorporated into the front face wall  210 , such members  400  may run lengthwise on one, two, three, or four sides of the front face wall  210  and may be contained or co-molded within the inwardly projecting rim or lip  214 . In order to provide flexibility in the upper portion  500  to facilitate insertion and removal of the mobile device into and out of the case  200 , it may be preferable not to include such members  400  in all the sides or portions of the upper regions, such as the corner regions and/or regions surrounding the buttons and apertures. 
         [0056]    Reinforcing support members  400  may be incorporated into the case  200  with reference to structural analysis of the mobile device. Thus, for example such reinforcing support members  400  may be incorporated in the case to be configured to be at or near regions of the mobile device that are prone to bending, such as around end regions or underlying areas of structural weakness such as near buttons or apertures. Thus, a preferred implementation would include one or more reinforcing support members  400  that are configured to reside in proximity to such areas of structural weakness. 
         [0057]    The various aspects relating to configuration and construction of each of the two component layers described above or otherwise herein and/or illustrated in the drawings may be formed during the molding process.
