     BACKGROUND 
     1. Technical Field 
     The present disclosure relates generally to mounts for securing mobile devices to a structure, and more particularly, to a vent-attached mobile device mount accepting air freshener fragrance cartridges. 
     2. Related Art 
     A wide variety of portable electronic devices are currently in existence on the market, though there has been a recent convergence towards a fewer category of devices that fulfill many needs. Typically, these are smartphones that which integrate functions and features that may have earlier been provided in separate, independent devices such as music players, gaming consoles, personal digital assistants, digital still and video cameras, electronic readers, mapping and navigation devices, and so on. Several short-to-medium range communications modalities are also integrated, including WiFi and Bluetooth for short-range/local data transfer links, as well as cellular communications systems that can substantially extend its communicative range. 
     When interacting with the smartphone for a brief moment, it may be held in the hand and placed back down following use. However, there may be some situations in which the user is performing a primary task not with or relating to the smartphone, e.g., driving a vehicle, working on a computer, cooking, and so on, but would nevertheless desire to access a function or view something on the smartphone. 
     In response to these needs, various mounting devices have been developed. One configuration is a cradle that mechanically retains the smartphone, with the cradle being mounted to a structure. The compressive retention mechanisms are oftentimes cumbersome to engage and/or disengage, so more recently, magnetic mounts are being utilized. A mount head including one or more permanent magnets are fixed to the structure, with a metallic plate being attached to the rear of the smartphone. The magnets on the mount engage the metallic plate, thereby releasably engaging the smartphone to the mount. Whether utilizing a compressive or a magnetic retention, the mount is attached to a location within the interior of the vehicle that is visible and accessible by the driver and/or passengers. A variety of attachment modalities are known in the art, including suction cups and adhesives that secure the mount to a surface such as the windshield or the dashboard, adapters that fit within cupholders in the center console or within the compact disc player slot, as well as clips that attach to the louvers or grilles of air conditioning vents. 
     The use of air conditioning vents as a mounting location for mobile devices is relatively new, however, as vent mounts have been more common for air fresheners that are typically lighter in weight. The enclosed space of a vehicle interior tends to retain unpleasant odors from a variety of sources, and air fresheners may be utilized to adsorb, oxidize, sanitize, or mask the odorants. An inexpensive and widely used air freshener are the continuous action type, one example of which is a wick or reed impregnated with a volatile fluid with fragrance material. Such air fresheners may be hung from visors or placed in similar central locations within the interior of the vehicle. 
     Another continuous action type air freshener employs a gel material that incorporates the fragrance, and stored within a container, one surface of which is a semi-permeable material that allows the fragrance vapors to slowly disperse into the surrounding environment. These air fresheners may be mounted to the air conditioning vent, with either cooled or heated air further facilitating the dispersion of the fragrance vapors. Typical mounts utilized for such air fresheners had structural configurations matched to the relatively light weight thereof and were generally unsuitable for adaptation to heavier articles such as mobile devices. Several improvements to better retain and stabilize the mounts on the vent grilles/louvers that horizontally and vertically distribute load forces have been made. 
     There are a limited number of air conditioning vents in typical front dash on which various devices may be mounted. The driver seat is typically configured with left and right rear-facing vents, and the passenger seat is likewise configured with left and right rear-facing vents. Some vehicles may incorporate an additional central vent. The right driver-side vent is oftentimes partially obstructed by the steering wheel, so it is not an ideal location for a mobile device. Likewise, the left passenger-side vent is offset too much to the right and may also not be a practical location for mounting a mobile device. To optimize the circulation of fragrance in the vehicle, a centrally located air conditioning vent is preferable. 
     Accordingly, while there may be multiple air conditioning vents on which various devices can be mounted, the practical or usable mounting locations are more limited. Therefore, there is a need in the art for a consolidated air conditioning vent mount for mobile devices and air fresheners.

     DETAILED DESCRIPTION 
     The detailed description set forth below in connection with the appended drawings is intended as a description of the presently preferred embodiment of a magnetic device vent mount with a fragrance cartridge holder and is not intended to represent the only form in which it can be developed or utilized. The description sets forth the functions for developing and operating the mount in connection with the illustrated embodiments. It is to be understood, however, that the same or equivalent functions may be accomplished by different embodiments that are also intended to be encompassed within the scope of the present disclosure. It is further understood that the use of relational terms such as first, second, distal, proximal, left, right, and the like are used solely to distinguish one from another element without necessarily requiring or implying any actual such relationship or order between such elements. 
     With reference to  FIG. 1 , a first embodiment of a mounting device  10   a  has a magnetic mount head  12 , a cartridge housing  14  that accepts a fragrance cartridge  16 , and a vent mount  18 , each of which will be described in further detail below. It is generally contemplated that the magnetic mount head  12  engages with a corresponding metallic plate attached to, integral with, or otherwise coupled to an electronic device such as a cellular telephone, smartphone, phablet, tablet, and the like. The magnetic mount head  12  may be movably coupled to a stalk  20  that extends from the cartridge housing  14 . The vent mount  18 , in turn, is understood to be attachable to the louvers of a vehicle air conditioning vent to securely couple the magnetic mount head  12 , an electronic device attached thereto, the cartridge housing  14 , and the fragrance cartridge  16  received therein, to the air conditioning vent. 
     As shown in partially exploded perspective view of  FIG. 2  as well as the cross-sectional view of  FIG. 7 , the cartridge housing  14  is defined by an open top end  22 , a closed bottom end  24 , a front face  26 , and an opposed rear face  28 . In the exemplary configuration, the cartridge housing  14  is circular, and therefore the front face  26  and the opposed rear face  28  have a circular shape. The cartridge housing  14  additionally defines an internal cavity  30  within which the fragrance cartridge  16  is received, and so the cartridge housing  14  has a circumferential sidewall  32  that terminates at lip extremities  32   a ,  32   b  of the open top end  22 . The circular shape of the cartridge housing  14  is presented by way of example only and not of limitation, and any other suitable shape may be substituted. In this regard, the aforementioned features of the front face  26 , the rear face  28 , and the circumferential sidewall  32  thereof are likewise referenced in an exemplary sense only. To the extent the cartridge housing  14  has an alternative shape, alternative terms specific to such shapes are understood to be applicable. 
     Because the fragrance cartridge  16  is configured to be received within the cartridge housing  14 , it is understood to have a shape that generally conforms to the internal cavity  30  thereof, e.g., circular. More specifically, the fragrance cartridge  16  may have a partially toroid geometry with a rounded front portion  34  that defines a body  36  of the fragrance cartridge  16 , and a flat rear face  38  that is opposite the rounded front portion  34 . There is also a flange rim  40  that is a part of the flat rear face  38 . 
     With additional reference to  FIG. 3 , the body  36  of the fragrance cartridge  16 , as well the flat rear face  38  that backs the body  36 , has a U-shaped or horseshoe profile characterized by an engagement slot  42  that extends from the periphery to a central portion  44 . In further detail, the body  36  is generally defined by a semicircular base section  46  with a left branch  48   a  and a right branch  48   b  integral therewith. The left branch  48   a  and the right branch  48   b  are curved inwardly toward each other, with a left outer sidewall  50   a  and a right outer sidewall  50   b  terminating at a left tip  52   a  and a right tip  52   b , respectively. The outer sidewalls  50   a ,  50   b  are understood to be contiguous with an outer sidewall  50   c  of the semicircular base section  46 . 
     The engagement slot  42  is defined at least partly by a left inner sidewall  54   a  extending from the left tip  52   a , and a right inner sidewall  54   b  extending from the right tip  52   b . In addition, the engagement slot  42  is partly defined by a central semicircular inner sidewall  54   d  that is contiguous with the left inner sidewall  54   a  and the right inner sidewall  54   b . The central semicircular inner sidewall  54  generally corresponds to the central portion  44 . The width of the engagement slot  42  may be varied, though as will be described in further detail below, in one embodiment it is slightly wider than the diameter of the stalk  20 . The tips  52   a ,  52   b  may have a slight curvature to reduce any sharp edges that can snag within the internal cavity  30  of the cartridge housing  14 . 
     The flange rim  40  extends outwardly from the entire outline of the body  36 , and in a substantially perpendicular relationship to the respective inner and outer sidewalls  50 ,  54  described above. In this regard, the flange rim  40  may be structurally contiguous and/or have a uniform construction with the body  36 . The edges of the flange rim  40  are understood to conform to the outline of the body  36  and thus have a uniform width, with a few exceptions. 
     One such exception is a pair of left and right notches  56   a ,  56   b  defined in the flange rim  40  of the respective left and right branches  48   a ,  48   b  of the body  36 . As will be described in further detail below, the notches  56  are understood to frictionally engage with posts located within the internal cavity  30  so that the fragrance cartridge  16  remains within notwithstanding any minor vibration or jostling force typically encountered in a moving vehicle. In one exemplary embodiment, the notches  56  are circular with rounded edges. The flange rim  40  is understood to be constructed of a resilient plastic material that deforms in response to a certain degree of force applied thereto. Such force may be that which corresponds to a deliberate effort to manually remove the fragrance cartridge  16  from the cartridge housing  14 , or to insert the fragrance cartridge  16  into the internal cavity  30 . The specific positioning of the notches  56  relative to the center axis of the engagement slot  42 , which in turn is the insertion and removal axis  58 , is contemplated to facilitate such an removable engagement of the fragrance cartridge  16  and the cartridge housing  14 . 
     Another exception is an upper tab  60  extending from that portion of the flange rim  40  corresponding to the semicircular base section  46 . The upper tab  60  provides a surface by which t user can grasp the fragrance cartridge  16  in order to pull and remove the same from the cartridge housing  14 . Along these lines, the upper tab  60  may be pushed and inserted into the internal cavity  30 . 
     The body  36  of the fragrance cartridge  16  is understood to serve as the reservoir for a fluid material impregnated with a fragrance. To this end, the body  36  may be constructed of a resilient, non-permeable polymer material including polyethylene terephthalates (PET), polyethylene (PE), low-density polyethylene (LDPE), high density polyethylene (HDPE), polyvinyl chloride (PVC), polyamides or nylon, polyoxymethylene or Delrin, and so on. The body  36  may be transparent or translucent so that a user may immediately ascertain the volume of the fragrance fluid material that remains to decide that a replacement cartridge is necessary, and/or to distinguish one type of fragrance cartridge or another marked with different colorants. The fluid material may be a highly volatile liquid or oil. A variety of scents or fragrances that are either synthetically produced or naturally derived oils such as lavender, orange, lemon, vanilla, cedar, wood, sandalwood, and the like. Besides colorants and fragrances, the fluid material may incorporate other additives such as stabilizers, plasticizers, and/or lubricants. Furthermore, it is within the purview of one having ordinary skill in the art to select different fragrances, carrier fluids, colorants, and additives. There are numerous possible combinations and blends, and the present disclosure need not be limited to any particular one. 
     While the body  36  is not permeable, it is contemplated that the flat rear face  38  of the fragrance cartridge  16  may be. A thin, resilient though permeable film  62  may be affixed over the entirety of the fragrance cartridge reservoir and adhered to the flange rim  40 . Glue, or any other suitable adhesive may be utilized to so affix the permeable film  62  to the body  36 . The permeable film  62  is contemplated to slowly release the volatile fragrance material into the atmosphere. It will be appreciated that any suitable material may be utilized for the permeable film  62 , and further, any other suitable fragrance or volatile liquid release modality may be substituted without departing from the scope of the present disclosure. 
     As indicated above, the cartridge housing  14  includes the stalk  20  extending from a central portion  64  thereof. The stalk  20  includes a ball joint  65  that is either integral with or fixedly attached to the end of the stalk  20  and is configured to be rotatably coupled to the magnetic mount head  12 . In this regard, the ball joint  65  may also be referred to more generally as a primary rotatable joint. Although specific reference is made to the magnetic mount head  12 , this is by way of example only and the ball joint  65  may be rotatably coupled to any other cradle-type apparatus that holds an electronic device, or any other attachment, including those with device charging functionalities, auto-clamping functionalities, and so on. 
     Referring again to  FIG. 2  and the cross-sectional view of  FIG. 7 , the magnetic mount head  12  may be generally defined by a front face  66  and a head body  68 . The front face  66  may be an elastomeric covering  67  that conceals a set of magnets  69  mounted to the head body  68 , which in turn engages a ferromagnetic element. In one embodiment, this may be a standalone steel plate that is adhered to or otherwise attached to a mobile device or other object to be removably attached to the magnetic mount head  12 . 
     With additional reference to  FIG. 4 , the rear of the head body  68  defines a pocket  70 , within which there is a joint socket  72 . The pocket  70  has an interior wall  74  and a circular floor  76 . In the illustrated example, the joint socket  72  may be comprised of four socket tines  78   a ,  78   b ,  78   c , and  78   d  that are circularly positioned around the pocket  70  in a spaced relationship to each other. The interior surfaces of the socket tines  78   a - 748  are each understood to have a partial spherical contour corresponding in size and shape to the ball joint  65  that is positioned within the joint socket  72 . Along these lines, the tines  78  have an arcuate profile as part of such partial spherical contour. 
     Each of the tines  78  are understood to be slightly undersized relative to the size of the ball joint  65  so that it may be frictionally retained in a desirable orientation. The slight biasing force exerted in this configuration may be overcome by applying an axial force upon the ball joint  65 /stalk  20 . This is understood to spread apart the tines  78  to release the ball joint  65  from the grips of the joint socket  72 . In this regard, the tines  78  are spaced away from the interior wall  74  to allow for such spreading. Though a ball-and-socket joint is shown, this is by way of example only and any other rotating/articulating engagement between the magnetic mount head  12  and the cartridge housing  14  are possible. 
     Stability at the endpoints of the mounting device  10 , that is, the magnetic mount head  12  on one end, and the vent mount  18  at the opposite end, may be maximized by positioning each along the same axis, and attaching to a contiguous coaxial structure. More particularly, this structure extends through the cartridge housing  14  and intersects the internal cavity  30 . The engagement slot  42  defined in the body  36  of the fragrance cartridge  16  provides a passageway for the structure thus configured. The vent mount  18  extends from the rear face  28  of the cartridge housing  14  in a direction opposite the magnetic mount head  12 . 
     With reference to the exploded view of  FIG. 5  as well as the cross-sectional view of  FIG. 7 , the cartridge housing  14  may be comprised of various subcomponents that are so positioned along a common central mount axis  79 . Specifically, there may be a circular cover  80  with a cover face  82  that generally corresponds to the front face  26  referenced in the context of the overall cartridge housing  14 . Additionally, there is a sidewall  84  that generally corresponds to the aforementioned circumferential sidewall  32  similarly referenced in the context of the overall cartridge housing  14 . The sidewall  84  extends substantially around the circumference of the cover face  82 , terminating at a left end  84   a  as well as an opposite right end  84   b . Defined along the rim of the sidewall  84  are a series of venting indents  86  that permit the flow of air and fragrance material from the fragrance cartridge  16 . The cartridge housing  14  may at least be a combined assembly of the circular cover  80  and a circular stabilizer  88  each attached to a coupling  90 . 
     The circular stabilizer  88  is understood to have a circumference substantially corresponding to that of the circular cover  80 , and defined by a central hub  92  integral with a pair of upper and lower spokes  94   a ,  94   b  extending to a peripheral circular rim  96 . Within an interior region of the circular stabilizer  88 , there are left and right hemispherical slots  98   a ,  98   b . It is expressly contemplated that the hemispherical slots  98  open to the vehicle air conditioning vents, and exposes the permeable film  62  of the fragrance cartridge  16  to the airflow, aiding in the dispersion of the fragrance. The central hub  92  further defines a quadrangular recess  100  that receives a corresponding quadrangular flange  102  of the coupling  90 . The quadrangular recess  100  and the quadrangular flange  102  may be sized and shaped for a friction fit. The center of the circular stabilizer  88  is aligned with the common central mount axis  79 , and a fastener or screw  104  extends from the central hub  92  in alignment therewith. 
     The coupling  90  also includes a collar portion  106  abutting the quadrangular flange  102 , and defines a keyed bore  108  that receptively engages the stalk  20 . The axis of the keyed bore  108  is aligned and coaxial with the common central mount axis  79 , and also receives the screw  104 . The keyed bore  108  is so configured to prevent rotational movement of the stalk  20  when inserted therein according to one embodiment of the present disclosure. 
     In addition to being attached to the circular stabilizer  88 , the coupling  90  is also attached to the circular cover  80 . With additional reference to  FIG. 6 , there is an integral bushing  110  in the central portion  64  of the circular cover  80 . The center axis of the bushing  110  is understood to be in axial alignment with the common central mount axis  79 . The bushing  110  may further define a keyed opening  112  that has the same profile as the keyed bore  108  of the coupling  90  that is fitted within the bushing  110 . The coupling  90  has an extension  114  from the collar portion  106 , some sections of which are engaged to the bushing  110 . In other embodiments, the coupling  90  and the bushing  110  may be a unitary structure. The extension  114  includes a passageway  115  through which a transverse fastener  116  may be inserted to secure the coupling  90  to the circular cover  80  and/or the stalk  20  when inserted through the keyed opening  112  and the keyed bore  108  of the coupling  90 . The circular cover  80  additionally defines a cover slot  118  that extends from the outer periphery thereof to the central portion  64 . 
     As mentioned above, the cartridge housing  14  incorporates various structural features that aid in aligning and retaining the fragrance cartridge  16  within its internal cavity  30 . One such structural feature is the U-shaped fragrance cartridge  16  and the engagement slot  42 , within which the coupling  90  and/or the stalk  20  is received. Although in some embodiments the stalk  20  does not extend entirely through the coupling  90 , because the stalk  20  is fixed to the coupling  90 , the stalk  20  may be considered as being received within the engagement slot  42  of the fragrance cartridge  16  because the coupling  90  may be an extension of the stalk  20 . It is to be understood that while some features have been described as discrete components and subcomponents, different embodiments within the contemplation of the present disclosure may utilize different integrated combinations of features that form a unitary component or sub-component. 
     Another retention feature previously described is the series of notches  56  defined around the circumference of the flange rim  40  of the fragrance cartridge  16 . As best shown in  FIG. 6 , the interior side of the circular cover  80  includes a series of circumferentially spaced posts  120  that extend the entire depth of the sidewall  32 , and beyond. The notches  56  on the fragrance cartridge  16  are engageable to the posts  120  so that the fragrance cartridge  16  remains within the internal cavity  30 . 
     An interior of the circular cover  80  may further define a circular protuberance  124  in a middle region  122  between the outer periphery and the central portion  64  thereof that is contemplated to provide an interference fit against the rounded front portion  34  of the fragrance cartridge  16 . This circular protuberance  124  may be seen as a circular depression  125  on the cover face  82  of the circular cover  80 . During insertion of the fragrance cartridge  16 , the circular protuberance  124  partly inhibits such movement, but once fully inserted, the circular protuberance  124  is understood to clear the raised, rounded front portion  34  of the fragrance cartridge  16 . This feature is likewise contemplated to aid in the retention of the fragrance cartridge  16 . 
     The circular stabilizer  88 , and hence cartridge housing  14  of which it is a part, includes the vent mount  18  that is configured to couple the mounting device to the louvers of an air conditioner vent. The vent mount  18  is comprised of a metallic clip  126  with a base  128  and a pair of opposed claws  130 . There is a fastener hole  132  defined in the base  128 . The screw  104  may be inserted through the fastener hole  132 , and compress the base  128  against the circular stabilizer  88 . The clip  126 , and hence the vent mount  18 , is understood to be in axial alignment with the common central mount axis  79 . 
     The claws  130  may be received within an elastomeric jaw assembly  134  generally comprised of an upper jaw  134   a  and a lower jaw  134   b , with a common base  136 . In the illustrated example, the jaws  134  are vertically offset from each other, and define a horizontally oriented separate between which a horizontal vent louver is retained. Each of the upper and lower jaws  134   a ,  134   b  define respective cavities  138   a ,  138   b  that are receptive to the corresponding claws  130  of the metallic clip  126 . The upper jaw  134   a  and the lower jaw  134   b , like the claws  130  inserted therein, are configured to be movable relative to each other, and so there may be a joint structure  140  within the common base  136 . The claws  130  are biased toward each other, such that they exert a compressive force against the upper jaw  134   a  and the lower jaw  134   b . The jaws  134  may be spread apart manually to provide clearance for the vent louvers while the mounting device  10  is being attached thereto. Alternatively, the open end of the jaws  134  may be pressed on to the vent louvers and inserted further therein. Once fully attached on to the louvers, the jaws  134 , and the claws  130 , are understood to be compressively retained thereon. 
     In addition to defining a part of the cartridge housing  14 , the circular stabilizer  88  is contemplated to minimize rotational movement about transverse axes normal to the common central mount axis  79 . The peripheral circular rim  96  and interior portions of the circular stabilizer  88  may be abutted against the air conditioning vent louver and prevent from further rotation. To provide further frictional engagement to the vent louver, the rear side of the circular stabilizer  88  may include an elastomeric pad  142  that extends around the circumference of the circular stabilizer  88 . 
       FIGS. 8, 9 and 10  depict a second embodiment of the magnetic mounting device  10   b  that accepts the fragrance cartridge  16  within its housing  14 . Many of the same components utilized in the first embodiment  10   a  described above are also utilized in the second embodiment  10   b , including the vent mount  18  comprised of the same metallic clip  126  and elastomeric jaw assembly  134 . The metallic clip  126  is attached to the same circular stabilizer  88  with the screw  104 . Additionally attached to the rear of the circular stabilizer  88  is the elastomeric pad  142 . The housing  14  likewise includes the circular cover  80  with the bushing  110 , to which the stalk  20  is coupled. The screw  104  extends through the stabilizer  88 , an alternatively configured coupling  150 , and partly through the bushing  110 /circular cover  80 . The screw  104  is threaded and secured onto the stalk  20 , which accepts the magnetic mount head  12 . 
     The coupling  150  similarly includes a quadrangular flange  152  received within the quadrangular recess  100  defined by the circular stabilizer  88 . The coupling  150  is also defined by a collar portion  154 , with a through bore  156  extending through the collar portion  154 . The through bore  156  is stepped, and there is a wider counterbore  158  that is sized and shaped to accept a quadrangular key  160  at the tip of the stalk  20 . The collar portion  154  is received within a circular opening of the bushing  110 . 
     The closed bottom end  24  of the housing  14  further includes a drip catch  162  that attaches to the circular cover  80  with clips  164 . The drip catch  162  has partially circular catch body  166  with a front rim  168  and an opposed rear rim  170 . Additionally, there is a tapered inner rim  172  that conforms to the outer contour of the stabilizer  88 . In a central region  174  of the catch body  166 , there is a protuberance  176  that roughly conforms to the width of the engagement slot  42  of the fragrance cartridge  16 . The protuberance  186  is understood to frictionally retain, or at least position or align the fragrance cartridge  16  within the housing  14 , and prevent lateral movement of the same. 
     Referring again to  FIG. 1 , the embodiment of the mounting device  10   a  shown therein contemplates a direct coupling of the magnetic mount head  12  to the stalk  20 . That is, the magnetic mount head  12 , the stalk  20 , the cartridge housing  14 , and the vent mount  18  are arranged along the single common central mount axis  79 . As shown in  FIG. 11 , an offset extension bar  144  may be rotatably coupled to the stalk  20  and the ball joint  65  fixed thereto. More specifically, the offset extension bar  144  may be defined by a first or proximal end  146  that includes the same joint socket as those described above in relation to the magnetic mount head  12 . Such joint socket, in turn, may be rotatably coupled to the stalk  20 . The offset extension bar  144  may also be defined by a second or distal end  148 . This distal end  148  may include a joint base portion  150  to which a second stalk  152  is attached. At the end of the second stalk  152  may be another ball joint, which rotatably couples to the magnetic mount head  12 . In all respects, this magnetic mount head  12  is the same as that which was described above in the context of the first embodiment  10   a , so details thereof will be omitted. Because the offset extension bar  144  is rotatable relative to the stalk  20 , it may be extended to the left, to the right, to the bottom, to the top, or anywhere in between to better position and orient the magnetic mount head  12 . 
     The particulars shown herein are by way of example and for purposes of illustrative discussion of the embodiments of the present disclosure only and are presented in the cause of providing what is believed to be the most useful and readily understood description of the principles and conceptual aspects. In this regard, no attempt is made to show details with more particularity than is necessary, the description taken with the drawings making apparent to those skilled in the art how the several forms of the present disclosure may be embodied in practice.
