[0034] Referring to FIGS. 1 and 4, the accessory device 130 of the illustrated embodiment includes an outer shell 132, the mounting post 300, and the rotational stop tab 332. In various embodiments, the accessory device 130 includes various components, such as a display screen, user input devices (e.g., buttons, switches, sliders, and / or keys), communication ports, power delivery and / or charging ports, wireless charging components (e.g., to wirelessly charge the mobile device 25 when attached), speakers, microphones, SIM card trays, memory card trays, and / or other suitable components.

[0035] In the illustrated embodiment, the outer shell 132 has an oblong shape, including two short sides (top and bottom sides) and two long sides (left and right sides). Other configurations and / or shapes of the outer shell 132 are contemplated and within the scope of the present disclosure.

[0036] In various embodiments, the accessory device 130 includes one or more magnetic securement devices (not shown). In some embodiments, the magnetic securement devices of the accessory device 130 are aligned with magnetic securement devices 124 of the case 120, magnetic securement devices of the mobile device 25, and / or other suitable locations. These magnetic securement devices facilitate wireless charging, securing the accessory device 130 to the mobile device 25 and / or the case 120, alignment of the accessory device 130 with the mobile device 25 and / or case 120 (e.g., to align NFC antennas), and / or attaching the accessory device 130 to another surface.

[0037] As described above, the mounting post 300 includes the inner column 310 and the outer flange 320. In various embodiments, the mounting post 300 extends from a front face 132a of the outer shell 132 of the accessory device 130 and provides a structure onto which the post receiver 200 can be mounted.

[0038] In various embodiments, the inner column 310 includes a cylindrical shape, a hexagonal shape, an octagonal shape, or other suitable shape. In the embodiment shown in the figures, the mounting post 300 is configured to enable the post receiver 200 to be mounted in one orientation in which the case 120 and the accessory device 130 are aligned when assembled together (i.e., with a long axis of the case 120 parallel to a long axis of the accessory device 130). In other embodiments, the mounting post 300 has a different shape, such as a hexagon, octagon, circle, or other suitable shape that enables the accessory device 130 to be coupled with the case 120 at different orientations relative to the case 120 (i.e., landscape left, portrait, landscape right, and inverted portrait). In some embodiments, the inner column 310 is rotationally symmetrical to enable insertion of the mounting post 300 in any of a plurality of orientations. In some embodiments, the inner column 310 is rotationally asymmetrical to restrict insertion and / or rotation of the mounting post 300.

[0039] In various embodiments, the outer flange 320 includes a square shape, a hexagonal shape, an octagonal shape, or other suitable shape. In some embodiments, the outer flange 320 is rotationally symmetrical to enable insertion of the mounting post 300 in any of a plurality of orientations. In some embodiments, the outer flange 320 is rotationally asymmetrical to restrict insertion of the outer flange 320 into the stepped insertion channel 220 to one of a set of orientations (e.g., one, two, or more orientations). In some embodiments, the outer flange 320 is rotationally asymmetrical to restrict rotation of the mounting post 300 within the stepped insertion channel 220. In some embodiments, the outer flange 320 includes a non-uniform shape to enable the system 100 to restrict assembly to authorized accessory devices having an outer flange with that non-uniform shape.

[0040] In some embodiments, to facilitate assembly of the outer flange 320 into the stepped insertion channel 220, the outer flange 320 and / or inner column 310 include a chamfered edge, fillet edge (i.e., with a curved profile), and / or beveled edge. In the embodiment shown in FIG. 4, the outer flange 320 includes a chamfered edge between a front face 321 and an outer perimeter 322 and includes a chamfered edge around corners of the outer perimeter 322. In the embodiment shown in FIG. 4, the inner column 310 includes a chamfered edge around corners of an outer perimeter.

[0041] In various embodiments, the outer flange 320 is located at a distal end of the inner column 310. In other embodiments, the outer flange 320 is located inward from the distal end of the inner column 310, for example, to facilitate improved axial alignment of inner column 310 during insertion into the stepped insertion channel 220. In some such embodiments, the distal end of the inner column 310 includes a chamfered, filleted, or bullet-nose shape to facilitate insertion into the stepped insertion channel 220.

[0042] In various embodiments, the rotational stop tab 332 is configured to restrict rotation of the mounting post 300 when inserted into the rotational stop recess 334. The rotational stop tab 332 is sized to enable rotation of the mounting post 300 until a last translational movement of the mounting sequence for securing the mounting post 300 to the post receiver 200. During the last translational movement of the mounting sequence, the rotational stop tab 332 is inserted into the rotational stop recess 334 and restricts rotation of the mounting post 300 such that unmounting of the mounting post 300 from the post receiver 200 requires performing the steps of the mounting sequence in a reverse order, as described below.

[0043] In various embodiments, the case 120 includes a back wall 121, a plurality of side walls (not labeled), mounting fixtures 122, magnetic securement devices 124, the post receiver 200, and / or other suitable case features. The case 120 is configured to securely house the mobile device 25. In the example embodiment shown, the case 120 includes a one-piece body, but can include two, three, or more pieces in other embodiments. In various embodiments, the case 120 includes polycarbonate, polyoxymethylene, other suitable thermoplastics, carbon fiber reinforced polymer (“carbon fiber”), other fiber reinforced polymers (e.g., fiberglass reinforced nylon), thermoplastic polyurethane (TPU), silicone, and / or other suitable materials.

[0044] A front side of the back wall 121 and the side walls define a cavity or opening 126 in which the mobile device 25 is secured. In certain embodiments, the back wall 121 includes an outer shell 127 and a backer panel 128 that enclose all or a portion of each of the mounting fixtures 122, the magnetic securement devices 124, and / or the post receiver 200. The outer shell 127 includes a flange opening 127a configured to receive the outer flange 320 of the mounting post 300. In other words, a shape of the flange opening 127a matches a shape of the outer flange 320. The flange opening 127a provides an opening through a rear face 121a and a front face 121b of the back wall 121. In FIG. 3, the backer panel 128 is not shown to more clearly show the mounting fixtures 122, the magnetic securement devices 124, and the post receiver 200. In other embodiments, the outer shell 127 and the backer panel 128 are integrally formed.

[0045] In various embodiments, the case 120 includes one or more structural features, fasteners, and / or connectors that secure the mobile device 25 within the opening 126 of the case 120, for example, to promote retention of the mobile device 25 within the case 120 during forceful motions (e.g., a physical impact). In various embodiments, the case 120 includes an inner lip (not labeled) that extends around an inner perimeter of the side walls along an outer edge of the mobile device 25 and extends partially over a front face (i.e., a screen) of the mobile device 25. Other configurations of the inner lip and other means to secure the mobile device 25 within the case 120 are contemplated and within the scope of the present disclosure.

[0046] In some embodiments, the case 120 is an oblong case having two short sides and two long sides. In the example embodiment shown in FIGS. 2 and 3, the two short sides are left and right sides and the two long sides are top and bottom sides. In various embodiments, the case 120 includes one or more holes (not labeled) to facilitate user interaction with one or more components of the mobile device 25, such as communication ports, buttons, switches, speakers, microphones, SIM card trays, memory card trays, or other suitable components of the mobile device 25. In some embodiments, back wall 121 of the case 120 is configured to extend beyond a protrusion of the mobile device 25, such as a camera bump, which enables the case 120 to provide a flat surface on the rear face 121a of the back wall 121 for improved magnetic attachment, described below.

[0047] The mounting fixtures 122 are configured to secure a retention device to the case 120. In the example embodiment shown in FIG. 3 and FIG. 12, the case 120 includes an upper mounting fixture 122a, a first lower mounting fixture 122b, and a second lower mounting fixture 122c to which a retention device 1100 is connectable. In various embodiments, the retention device 1100 can selectively be connected to the upper mounting fixture 122a and one of the first lower mounting fixture 122b and the second lower mounting fixture 122c.

[0048] The retention device 1100 facilitates supporting the case 120 by a user's hand. In some embodiments, the retention device 1100 secures the case 120 to the user's hand. In the embodiment shown in FIG. 12, the retention device 1100 includes a hand strap configured to wrap around a back of a user's hand. In other embodiments, the retention device 1100 includes a clip that fits over the user's hand or another suitable retention device. In various embodiments, the retention device 1100 enables a user to hold the case 120 with their hand, but without wrapping a thumb or finger(s) around an edge of the case 120, which may cause inadvertent user inputs on a touch screen display of the mobile device 25.

[0049] In various embodiments, the magnetic securement devices 124 facilitate wireless charging, securing accessories for the mobile device 25, and / or attaching the mobile device 25 to another surface. In some embodiments, the magnetic securement devices 124 are configured to magnetically secure the accessory device 130 to the case 120 with a quick-release mechanism while still enabling a quick-release unmounting of the accessory device 130. In the example embodiment shown in FIG. 3, the magnetic securement devices 124 includes magnets, shown as magnetic securement devices 124a, 124b, 124c, 124d, and 124e. Specifically, the magnetic securement devices 124 are configured to magnetically secure the case 120 to the accessory device 130, to another magnetic securement device, and / or to another suitable magnetic material (i.e., ferrous metal).

[0050] Since the case 120 of the accessory mount system 100 includes the post receiver 200 generally formed as a recess within the case 120 as opposed to a post or other protruding structure, the case 120 is enabled to provide a flat surface on the rear face 121a of the back wall 121, which facilitates magnetic attachment of the case 120 to any suitable ferrous metal surface, such as a metal railing, a metal table, a hood of a car engine bay, or machinery where the mobile device 25 is being used.

[0051] During the mounting sequence, the post receiver 200 is configured to receive the mounting post 300 and thereby secure the accessory device 130 to the case 120 and mobile device 25. As described above, the post receiver 200 includes the rotational retention device 210 and the stepped insertion channel 220, while the mounting post 300 includes the inner column 310 and the outer flange 320.

[0052] In various embodiments, the mounting sequence for securing the mounting post 300 to the post receiver 200 includes both translational movements and rotational movements of one or both of the mounting post 300 and the post receiver 200 (i.e., the accessory device 130 and the case 120). Generally, the translational movements bring the front face 132a of the accessory device 130 and the rear face 121a of the case 120 close to each other and the rotational movements rotate the mounting post 300 relative to the post receiver 200 to enable further insertion of the mounting post 300. More specifically, the outer flange 320 of the mounting post 300 is insertable into the stepped insertion channel 220 until stopped by a step or wall of the stepped insertion channel 220. The outer flange 320 is then rotatable within the stepped insertion channel 220 to bypass the step or wall and enable further insertion of the outer flange 320 into the stepped insertion channel 220.

[0053] Referring to FIGS. 7A, 7B, 7C, 8A, 8B, and 8C, an example mounting sequence for securing the mounting post 300 to the post receiver 200 is shown. The rotational retention device 210 is configured to guide the rotation of the outer flange 320 from an unsecured rotational position 700 (FIG. 7A and FIG. 8A) through an intermediate rotational position 720 (FIG. 7B and FIG. 8B) to a secured rotational position 730 (FIG. 7C and FIG. 8C). In the unsecured rotational position 700, the mounting post 300 is removable from the post receiver 200 by a translational force to separate the two components. In the secured rotational position 730, the mounting post 300 is prevented from being removed by a translational force by the outer shell 127. In the secured rotational position 730, the accessory mount system 100 reduces a likelihood of accidental separation of the accessory device 130 from the case 120.

[0054] In various embodiments, the rotational retention device 210 is configured to: (1) provide a rotational snap-fit engagement for the mounting post 300 between two or more rotational positions; (2) guide rotational movement of the mounting post 300 between the rotational positions along the path through the stepped insertion channel 220; and / or (3) guide translational movement of the mounting post 300 along the path through the stepped insertion channel 220. For the rotational snap-fit engagement, the rotational retention device 210 is configured to provide at least some resistance to rotation of the mounting post 300, but enable rotation of the mounting post 300 between the rotational positions, as described below.

[0055] The rotational retention device 210 includes a spring arm device 211 that provides the resistance to rotation of the mounting post 300. As seen in FIG. 5, the spring arm device 211 of the example embodiment includes four spring arms 212 located at a different position about the rotational retention device 210, shown individually as spring arms 212a, 212b, 212c, and 212d. The spring arms 212 are bendable (i.e., elastically deformable) to provide the resistance to rotation of the mounting post 300. Specifically, the outer flange 320 is configured to engage the spring arms 212 when the outer flange 320 is rotated between the rotational positions, causing the spring arms 212 to bend outwards and then return inwards. In other embodiments, the rotational retention device 210 includes another elastically deformable component and / or magnets instead of, or in addition to, the spring arm device 211 to provide the resistance to the rotation of the mounting post 300. In some such embodiments, the spring arm device 211 provides one stage of resistance for a first rotational range of the mounting post 300 and the magnets provide another stage of resistance for a second rotational range of the mounting post 300. In some such embodiments, the first and second rotational ranges overlap.

[0056] In various embodiments, the rotational retention device 210 includes a flange guide 214 that guides rotational and / or translational movement of the outer flange 320 along the path through the stepped insertion channel 220. In other embodiments, the flange guide is separate from the rotational retention device 210. In some embodiments, the rotational retention device 210 includes the outer shell 127, the rear face 128a of the backer panel 128, and the flange guide 214 that are configured to guide the translational movement of the outer flange 320 along the path through the stepped insertion channel 220.

[0057] In various embodiments, the flange guide 214 includes one or more steps and one or more riser faces that are configured to guide and / or limit movement of the outer flange 320 along the path through the stepped insertion channel 220. The steps guide translational movement of the outer flange 320, for example, by stopping insertion of the outer flange 320 when the outer flange abuts one or more of the steps. The riser faces guide rotational movement of the outer flange 320, for example, by stopping rotation of the outer flange 320 when the outer flange abuts one or more of the riser faces. Although the steps and riser faces are shown separately and at right angles to each other, in some embodiments, the flange guide 214 includes an angled riser face (not shown) that guides a compound movement (i.e., both a translational movement and a rotational movement) of the outer flange 320.

[0058] In various embodiments, the flange guide 214 includes one or more groups of steps in which each step of a group is located at a different position about an axial center of the flange guide 214 (e.g., around a perimeter of the outer flange 320 when inserted into the stepped insertion channel 220). In some embodiments, the flange guide 214 includes one or more groups of riser faces in which each riser face of a group is located at a different position about the axial center of the flange guide 214.

[0059] In the embodiment shown in FIGS. 5 and 6, the flange guide 214 includes a group of middle channel steps 215, a group of middle channel riser faces 216, and a group of inner channel riser faces 217. In this example embodiment, each of the middle channel steps 215 has a same configuration, each of the middle channel riser faces 216 has a same configuration, and each of the inner channel riser faces 217 has a same configuration. Other implementations and / or different configurations of these groups and other configurations of steps and / or riser faces within these groups are contemplated and within the scope of the present disclosure.

[0060] For clarity and brevity, only one step and riser face of each of the group of middle channel steps 215, the group of middle channel riser faces 216, and the group of inner channel riser faces 217 is labeled and described herein.

[0061] For the stepped insertion channel 220, in the embodiment shown in FIGS. 5 and 6, the flange opening 127a of the outer shell 127, the flange guide 214, and the rear face 128a of the backer panel 128 form the stepped insertion channel 220. Specifically, the outer channel 220a is defined at least in part by the flange opening 127a. The middle channel 220b is defined at least in part by the middle channel step 215, middle channel riser face 216, the inner channel riser face 217, the spring arms 212, and the front face 121b of the back wall 121 of the case 120. The inner channel 220c is defined at least in part by the inner channel riser face 217, the spring arms 212, and the rear face 128a of the backer panel 128.

[0062] In various embodiments, the outer channel 220a is configured to restrict insertion and rotation of the outer flange 320 to the unsecured rotational position 700 of the outer flange 320 shown in FIG. 7A. When the outer flange 320 is in the unsecured rotational position 700, the outer channel 220a enables translational movement (i.e., insertion) of the outer flange 320 into the outer channel 220a and further into the middle channel 220b of the stepped insertion channel 220, but restricts rotation of the outer flange 320.

[0063] In various embodiments, the middle channel 220b is configured to enable at least some rotation of the outer flange 320, for example, between the unsecured rotational position 700 shown in FIG. 7A and the secured rotational position 730 shown in FIG. 7C. In other words, the middle channel 220b restricts rotation of the outer flange 320 to a predetermined range of rotation. When the outer flange 320 is inserted into the middle channel 220b from the outer channel 220a, the outer flange 320 becomes rotatable within the predetermined range of rotation.

[0064] In various embodiments, the middle channel 220b is configured to restrict translational movement of the outer flange 320 within at least some of the predetermined range of rotation. In some embodiments, the middle channel 220b prevents the outer flange 320 from being pulled away from the post receiver 200 to prevent accidental removal and / or separation of the accessory device 130 from the case 120. Specifically, when the outer flange 320 has been rotated away from the unsecured rotational position 700, for example, to the intermediate rotational position 720 (FIG. 7B), the front face 121b of the back wall 121 prevents removal of the outer flange 320 without first rotating the outer flange 320 back to the unsecured rotational position 700 (FIG. 7A).

[0065] In some embodiments, the middle channel 220b prevents the outer flange 320 from being inserted further into the stepped insertion channel 220 until the outer flange 320 has been rotated to the secured rotational position 730 (FIG. 7C). Specifically, the middle channel step 215 is configured to prevent further insertion of the outer flange 320 until the outer flange 320 has been sufficiently rotated to bypass the middle channel step 215.

[0066] In various embodiments, the middle channel 220b is configured to enable at least some translational movement of the outer flange 320. Specifically, when the outer flange 320 is in the unsecured rotational position 700 (FIG. 7A), the middle channel 220b enables translational movement (i.e., removal) of the outer flange 320 from the middle channel 220b into the outer channel 220a. Similarly, when the outer flange 320 is in the secured rotational position 730, the middle channel 220b enables translational movement (i.e., further insertion) of the outer flange 320 into the inner channel 220c of the stepped insertion channel 220.

[0067] In various embodiments, the inner channel 220c is configured to restrict rotation of the outer flange 320 to the secured rotational position 730 (FIG. 7A). When the outer flange 320 is in the secured rotational position 730, the inner channel 220c enables translational movement (i.e., insertion) of the outer flange 320 from the middle channel 220b into the inner channel 220c, but restricts rotation of the outer flange 320.

[0068] In various embodiments, each channel of the stepped insertion channel 220 is associated with a direction of movement and adjacent channels are associated with different directions of movement. In the example embodiment described above, the outer channel 220a is associated with translational movement in a first direction, the middle channel 220b is associated with rotational movement in a second direction, and the inner channel 220c is associated with translational movement in a third direction. In other embodiments, one or more channels of the stepped insertion channel 220 is associated with a compound direction of movement having both a translational component and a rotational component (e.g., a screw-like direction that rotates and moves inward).

[0069] Turning to FIGS. 9A, 9B, 9C, 9D, and 9E, and FIGS. 10A, 10B, and 10C the example mounting sequence for the accessory mount system 100 using the case 120 and the accessory device 130 is shown from a left side view. The mounting sequence can be performed by a user of the mobile device 25, for example. For clarity, the mounting sequence is now described with the case 120 and post receiver 200 in a fixed position, while the accessory device 130 and mounting post 300 undergo translational movements and rotational movements (relative to the case 120) between a first position 902, a second position 904, a third position 906, a fourth position 908, and a fifth position 910. Each of these positions includes a rotational position and a translational position. In other embodiments and / or scenarios, the accessory device 130 and mounting post 300 are fixed while the case 120 and post receiver 200 undergo translational movements and rotational movements. In other embodiments and / or scenarios, both the case 120 and the accessory device 130 undergo translational and / or rotational movements. Although example rotations and distances are described below in the mounting sequence, such rotations and distances are not intended to limit the invention.

[0070] In FIG. 9A, the first position 902 of the accessory device 130 includes a first rotational position and a first translational position. In the first position 902, the mobile device 25 is not secured to the accessory device 130, the rear face 121a of the back wall 121 of the case 120 is facing the front face 132a of the outer shell of the accessory device 130, and the left and right sides of the case 120 are aligned in parallel with left and right sides of the accessory device 130. In the first rotational position, the outer flange 320 is in the secured rotational position 730 (FIG. 7C and FIG. 8C). In the first translational position, the rear face 121a is separated from the front face 132a by a first distance of approximately 10 millimeters. From the first position 902, the user moves the accessory device 130 into the second position 904 by performing a first rotational movement on the accessory device 130.

[0071] In FIG. 9B, the second position 904 of the accessory device 130 includes a second rotational position and the first translational position. In the second rotational position, the accessory device 130 has been rotated about a central axis of the mounting post 300 by approximately 45 degrees in a first direction. With this rotation, the outer flange 320 is in the unsecured rotational position 700 (FIG. 7A and FIG. 8A). As described above, the unsecured rotational position 700 enables the outer flange 320 to be inserted into the outer channel 220a of the stepped insertion channel 220. From the second position 904, the user moves the accessory device 130 into the third position 906 by performing a first translational movement on the accessory device 130.

[0072] In FIG. 9C and FIG. 10A, the third position 906 of the accessory device 130 includes the second rotational position and a second translational position. In the second translational position, the rear face 121a is separated from the front face 132a by a second distance of approximately 2 millimeters. With the first translational movement to the second translational position, the outer flange 320 is inserted through the outer channel 220a and into the middle channel 220b. From the third position 906, the user moves the accessory device 130 into the fourth position 908 by performing a second rotational movement on the accessory device 130.

[0073] In FIG. 9D and FIG. 10B, the fourth position 908 of the accessory device 130 includes the first rotational position and the second translational position. For this fourth position 908, the accessory device 130 has been rotated back to the first rotational position (i.e., rotated about the central axis of the mounting post 300 by approximately 45 degrees in a second direction that is opposite the first direction). With this rotation, the outer flange 320 is in the secured rotational position 730 (FIG. 7C and FIG. 8C). From the fourth position 908, the user moves the accessory device 130 into the fifth position 910 by performing a second translational movement on the accessory device 130.

[0074] In various embodiments, the magnetic securement devices 124 of the case 120 engage the magnetic securement devices of the accessory device 130 to secure the accessory device 130 in the first rotational position when the accessory device 130 is moved into the second translational position. In other words, the magnetic securement devices 124 are configured to have a magnetic strength that provides reduced resistance to rotation in the first translational position and increased resistance to rotation in the second translational position.

[0075] In FIG. 9E and FIG. 10C, the fifth position 910 of the accessory device 130 includes the first rotational position and a third translational position. In the fifth position 910, the accessory device 130 is secured to the mobile device 25. In the third translational position, the rear face 121a is no longer separated from the front face 132a (i.e., the rear face 121a abuts the front face 132a). With this translational position: (1) the outer flange 320 is inserted through the middle channel 220b and into the inner channel 220c; and (2) the rotational stop tab 332 is inserted into the rotational stop recess 334 (i.e., the rotational stop 330 is engaged). As described above, the rotational stop 330 restricts rotation of the mounting post 300 such that unmounting of the mounting post 300 from the post receiver 200 requires performing the steps of the mounting sequence in a reverse order. That is, the inverse of the second translational movement is performed to enable rotation of the mounting post 300.

[0076] In various embodiments, the magnetic securement devices 124 of the case 120 engage the magnetic securement devices of the accessory device 130 to secure the accessory device 130 in the first rotational position and the third translational position when the accessory device 130 is moved into the third translational position.

[0077] For removal of the accessory device 130 from the case 120, the user performs the movements above in the reverse order. The flange guide 214 is configured to provide tactile feedback to the user to facilitate assembly and removal of the accessory device 130, for example, by limiting movements of the outer flange 320 to those movements that either assemble or remove the outer flange 320 from the stepped insertion channel 220.

[0078] In various embodiments, the magnetic securement devices 124 are configured to provide a translational retention force that the user must exceed to pull the accessory device 130 from the fifth position 910 to the fourth position 908 and thereby enable rotation of the accessory device 130. In some such embodiments, the translational retention force reduces accidental or unintentional removal of the accessory device 130 from the case 120.

[0079] In various embodiments, the rotational retention device 210 is configured to provide a rotational retention force that the user must exceed to rotate the accessory device from the fourth position 908 to the third position 906. In some such embodiments, the rotational retention force reduces accidental or unintentional removal of the accessory device 130 from the case 120. In some embodiments, the rotational retention device 210 is configured to provide the rotational retention force in only one direction that resists removal of the accessory device 130. In some embodiments, the rotational retention device 210 is configured to provide different rotational retention forces in different directions, specifically, a higher rotational retention force in one direction that resists removal of the accessory device 130 and a lower rotational retention force in an opposite direction that resists attachment of the accessory device 130 to the case 120. In some such embodiments, the lower rotational retention force provides tactile feedback to the user during attachment.

[0080] Although the mounting sequence described above employs two rotational movements and two translational movements, the mounting sequence is not limited to these movements. In various embodiments, the mounting sequence includes at least two translational movements of the outer flange 320 and at least one rotational movement of the outer flange 320. In various embodiments, the translational movements and rotational movements are performed alternately (e.g., interleaved) with each other.

[0081] In some embodiments, the mounting sequence includes: (1) a first translational movement (e.g., from the second position 904 to the third position 906); (2) a first rotational movement (e.g., from the third position 906 to the fourth position 908); and (3) a second translational movement (e.g., from the fourth position 908 to the fifth position 910). In some other embodiments, the mounting sequence further includes additional interleaved rotational movements and translational movements.

[0082] Turning to FIG. 11, another embodiment of the accessory mount system 100 includes a latch mechanism 1010. In various embodiments, the accessory mount system 100 includes the latch mechanism 1010 alternatively, or addition to, the rotational retention device 210.

[0083] In various embodiments, the latch mechanism 1010 includes one or more retractable tabs configured to lock the accessory device 130 to the case 120, for example, to prevent accidental removal of the accessory device 130. The retractable tabs are movable between an extended position in which the mounting post 300 is secured to the post receiver 200 and a retracted position in which the mounting post 300 is releasable from the post receiver 200. In the example embodiment shown in FIG. 11, the outer flange 320 includes two retractable tabs 1022 (shown individually as 1022a and 1022b) that extend radially outward from a center axis of the mounting post 300.

[0084] In various embodiments, the accessory device 130 includes a tab actuator (not shown), such as a lever, switch, button, electro-mechanical actuator, or other suitable actuator, that selectively causes the retractable tabs 1022 to extend outward to lock the accessory device 130 and / or retract inward to release (or enable the release of) the accessory device 130. In some embodiments, the latch mechanism 1010 includes a spring arm or other suitable elastically deformable component that causes the retractable tabs 1022 to return to the extended position when the tab actuator is released. In other words, the retractable tabs 1022 are biased towards the extended position and actuation of the tab actuator causes the retractable tabs 1022 to retract inwards.

[0085] In various embodiments, the latch mechanism 1010 includes magnetic securement devices 1024. In the embodiment shown in FIG. 11, the magnetic securement devices 1024 are shown individually as magnetic securement devices 1024a and 1024b. In some embodiments, the magnetic securement devices 1024 are aligned with magnetic securement devices 124 of the case 120, magnetic securement devices of the mobile device 25, and / or other suitable locations. The magnetic securement devices 1024 facilitate wireless charging, securing the accessory device 130 to the mobile device 25 and / or the case 120, alignment of the accessory device 130 with the mobile device 25 and / or case 120 (e.g., to align NFC antennas), and / or attaching the accessory device 130 to another surface.

[0086] Although only a single example post receiver 200 and example mounting post 300 are shown in the example embodiment, other variations of these components are contemplated and within the scope of the present disclosure. Similarly, other variations of the case 120 and the accessory device 130 are contemplated and within the scope of the present disclosure.

[0087] In various embodiments, the mounting post 300 is configured to be coupled with any of a plurality of different cases that include a suitable post receiver 200, for example, as a modular accessory to the different cases.

[0088] It should be appreciated that the post receiver 200, the mounting post 300, the case 120, and the accessory device 130 can vary in accordance with the present disclosure. For example, the post receiver 200 and the mounting post 300 can employ different sizes and shapes of the mounting post 300 and stepped insertion channel 220. Although the stepped insertion channel 220 includes three separate channels, the stepped insertion channel 220 can include two, four, or more separate channels in other embodiments.
