RELATED APPLICATIONS 
       [0001]    This application claims priority to U.S. Provisional Patent Application 62/171,284, of the same title, filed on Jun. 5, 2015, which is hereby incorporated by reference in its entirety. 
     
    
     BACKGROUND 
       [0002]    Field 
         [0003]    The present disclosure is generally related to a device for attaching to a mobile device, allowing a user of the mobile device to grasp and manipulate the device in a secure manner. 
         [0004]    Description of the Related Art 
         [0005]    Personal digital assistants, portable music players, cell phones, and other mobile devices have become omni-present indispensable devices in frequent use throughout a user&#39;s day. They are so important that owners dread dropping these devices and harming them. Owners also dread exposing them to environments known to be injurious, such as water or other liquids. 
         [0006]    Attempts to prevent harm to such devices include a variety of colorful and impact-resistant plastic and rubberized shells, which cushion the inner electronics in the event of a drop or other impact. Plastic waterproof covers may also be helpful. Shells, however, tend to cover only one larger surface of the device, such as a back surface, and perhaps the sides, thus leaving unprotected large areas, such as the user&#39;s screen. Plastic covers may provide more protection, but must typically be removed or opened in order to use the device. Shells and waterproof covers also typically conform to the basic form of the device and therefore do not offer the device user an enhanced grip apart from that perhaps provided by the rubberized surface or texture of the shell. Mobile device attachments that currently exist are either fixed in their placement on a mobile device, forcing a limited range of motion as regards positions in which a user may hold the device and/or the device attachment is bulky, making it difficult for a user to, for example, place the device in a pocket or carrying case as would be possible were it not for the bulk of the device attachment. 
         [0007]    Therefore, what is needed is a collapsible apparatus offering a range of rotation that may be affixed to a mobile device and used to hold and support the device.

       DETAILED DESCRIPTION 
       [0047]    The present application discloses a unique product for enhancing the functionality of hand-held devices, such as a mobile device. Affixing the attachment device, which may be known in the trade as a “amänō” to a mobile device provides a secure attachment and may allow for holding the mobile device with, for example, a single finger. With this attachment, one is able to hold and use device with confidence that the user will not drop the device, possibly causing damage. In one embodiment, the amänō or attachment device may comprise three or more separate concentric round “rings” allowing a unique edge swivel. In an example embodiment, the attachment device may include three concentric rings, the outer ring of which may be affixed to a backing plate. The bottom portion of the backing plate may be covered in an adhesive that may be used to affix the attachment device to a mobile device. The adhesive may be protected until usage by a protective film that may be removed by a user prior to affixing the backing plate to a mobile device. In embodiments, the adhesive may be a repositionable adhesive. This may allow a user to place and remove the attachment device from a mobile device, and/or use the same attachment device on a plurality of mobile devices. In embodiments, the backing plate may be affixed to the mobile device using a non-adhesive, including but not limited to a suction cup, clip, or some other means of securing the attachment device. The attachment device may include a middle ring that is positioned within the outer ring. The outer ring may have a recessed area extending the inner circumference of the outer ring that accommodates a lock ring. The middle ring may have a recessed area extending the outer circumference of the middle ring that accommodates the lock ring. The lock ring when secured within the recessed portions of the outer and middle rings may hold the middle ring secure to the outer ring and allow for swivel or rotation (possibly of 360-degree range) along the inner portion of the outer ring, where the rotation is parallel to the plane of the backing plate. An inner ring may be secured to the middle ring using a lock ring within a hinge mount. The hinge mount may allow for the inner ring to have a 90-degree range of motion, or a range of motion less than 90-degrees, from its closed position to its fully opened position. In another embodiment, the inner ring may have a greater than 90-degree freedom of movement between a closed position and a fully open position, based at least in part on utilizing a spring hinge or some other type of hinge or pivot. Because the inner ring is mounted at the hinge mount to the middle ring, the inner ring may also swivel 360-degrees, or less than 360-degrees, in conjunction with the middle ring, in full rotation around the inner perimeter of the outer ring. This may allow for a customizable fit and personalized experience for the user. 
         [0048]    Referring to  FIG. 1 , the attachment device  10  includes an outer ring  12 , a middle ring  14  and an inner ring  16 , shown here in a fully upright position, so that a user may insert a finger, thumb, or non-human element such as a device stand or other apparatus, through the center of the ring  16 . The inner ring  16  may hinge about a hinge mount  18 , using a lock pin disclosed in later drawings. A side view of the attachment device  10  is shown in  FIG. 2 , with a bottom or outer ring  12  and the fully extended inner ring  16 . As seen in  FIG. 3A , the backing plate  30  of ring  10  is flat. In embodiments, the backing plate may not be entirely flat, but may for example have beveled or curved edges, a grooved surface, a patterned surface, a textured surface, or some other type of plate surface area that is not entirely flat. In addition, the backing plate bottom may include an adhesive pad  32  for securing the attachment device to a mobile device. The adhesive may cover a part of the bottom surface, as shown in  FIG. 3A , or may cover the entire bottom surface, as shown in  FIG. 3B . The adhesive pad may also include an outer release liner  34  for removal before adhering the device to a user instrument, such as a cell phone or a smart phone. The views of  FIGS. 3A-3B  also depict small portions of the upright inner ring  16  extending slightly beyond the bottom or outer ring  12 , when the inner ring is in an open position, 90-degrees relative to the plane of the backing plate. 
         [0049]    The backing plate may include a pad with a generally circular shape, a hollow circle or other desired shape. The greater the surface coverage with the adhesive, the more firmly the user device will hold the attachment device. In general, but not inevitably, the attachment device will be manufactured separately from the user devices contemplated herein. In some embodiments, the outer ring may include an adhesive pad, with no backing plate, for adhering the attachment device to the user device. In some embodiments, the adhesive may be furnished on a roll with pre-cut pads having a bottom adhesive surface for immediate application to the bottom of the attachment device. Each pad may also have an opposite side with a removable adhesive liner, so that a buyer and user of the attachment device may remove the protective removable adhesive liner and attach the attachment device to the user device of his or her choosing. 
         [0050]    The same attachment device  10  is depicted in  FIGS. 4-6 , in a partially-opened position. In  FIG. 4 , outer ring  12  is adjacent middle ring  14 , which mounts inner ring  16  via a hinge mount  18 . As seen earlier, it is possible to orient or raise inner ring  16  at a right-angle to the outer ring, and as seen below, the inner ring may also be closed up with the outer ring. In this embodiment, inner ring  16  is at about a 45-degree angle to the outer ring. In some embodiments, the hinging action of ring  16  about the hinge mount  18  is not smooth and has a degree of friction, so that when the user orients the rings as desired, and lays down the attachment device, along with a user device or user&#39;s mobile device, the orientation is maintained. The orientation of the rings does not shift of its own accord or under the weight of a small, portable user device. This may allow for the attachment device to be used as a stand for the device to which it is attached. For example, the attachment device may be used in this manner to hold a tablet computer at a 45-degree (or some other) angle while resting on a tabletop to facilitate hands-free viewing by a user of the tablet. The backing plate  30  is also visible in  FIGS. 4-5 . In another embodiment, friction between the inner  16 , middle  14  and/or outer rings  12  may cause the movement of a ring to be minimized, slowed or halted in its rotation. 
         [0051]      FIG. 5  is a front perspective view of attachment device  10  in a closed orientation, showing the generally flat top surface formed by outer ring  12 , middle ring  14  and inner ring  16 . The flatness of the top surface can be seen also in the side view of  FIG. 6 , in which can be seen the device  10  and the outer ring  12 . In embodiments, the components of the attachment device are smooth and can be used with sometimes-expensive user devices without fear of gouging or scratching. For example, the component parts, if made of metal, plastics or composites that are sufficiently hard could scratch a user&#39;s other property, such as a tablet computer, or another user device of the type contemplated herein for use with the attachment device. Thus, if necessary, the parts may be deburred or polished, as necessary, to prevent catching on clothing, scratching of user devices or otherwise interfering with the user. 
         [0052]    Examples of user devices which may advantageously use the attachment device include cell phones, smart phones, personal digital assistants, calculators, MP 3  players, iPods, iPads, tablet computers and similar, mobile or small devices intended for digital interaction with a user. Other devices may be used as desired. In an embodiment, the attachment device may be used to hold a clipboard, pad, or other surface area. In embodiments, the attachment device may be affixed to a post, such as an adjustable post that may be used to mount the attachment device and the object to which it is attached, such as mounting to a dashboard of a car, countertop, wall, tabletop, or some other surface. 
         [0053]      FIGS. 7-12  depict the component parts that may advantageously be used for the attachment device. In this embodiment, details of outer ring  12  are disclosed in  FIGS. 7-8 . Outer ring  12  includes an outer surface  72 , an inner surface  74  and an inner recess  76 , which may be used to accommodate a lock ring, useful for locking together outer ring  12  and middle ring  14 . Note also in  FIG. 7 , the bottom surface  78  of outer ring  12  is solid, rather than hollow. Maintaining a solid bottom  78  allows for greater strength and stiffness in the outer ring and in the attachment device. As noted, in this example embodiment the outer ring and backing plate are one piece, the bottom surface of which provides a surface area for mounting outer ring  12  and its bottom  78  to the user device. In alternate embodiments, the outer ring and backing plate may be separate components that are affixed to one another via integral manufacture, an adhesive, a mechanical connection or some other manner of attachment. 
         [0054]    The lock ring, as well as the other portions of the attachment device, enjoys a good deal of freedom in the materials that may be used. The lock ring may have a shape of an o-ring, i.e., a generally round shape or having a circular cross-section. The lock ring alternately may have a generally oval or elliptical shape. The lock ring may alternatively have a shape of a rounded square or rounded rectangle. The lock ring may be made of metal, elastomer, plastic, composite or some other material. The ring ideally should have sufficient flexibility to allow assembly and sufficient rigidity to resist disassembly. 
         [0055]    Perspective and cross-sectional views, respectively, of an embodiment of middle ring  14  are disclosed in  FIGS. 9-10 . In  FIG. 9 , middle ring  14  includes an inner surface  92 , an outer surface  94  and a recess  96  in the outer surface. The recess  96  provides space for a lock ring  99 , which is used to secure the middle ring  14  to outer ring  12 , using the recess  76  in the inner surface  74  of the outer ring and the recess  96  in the outer surface  94  of the middle ring  14 . The lock ring  99  fills the recesses  76 ,  96  of the outer and middle rings and interferes with attempts to disassemble the outer and middle rings. Thus, the attachment device is strong and stable, but ultimately can be disassembled if the parts include sufficient tolerances. Middle ring  14  also includes a gap  98  to accommodate the hinge mount  18  of the inner ring. The length of lock ring  99  is a little less than the circumferential length of the recesses  76 ,  96 , so that a lock pin can be used in this space, described below. In embodiments, parts with tighter tolerances may be considered to be permanently assembled, while parts with greater tolerances may be easier to disassemble. User devices may be safer with attachment devices having tighter tolerances and a lower chance of disassembly or failure. 
         [0056]    Other embodiments of the device attachment may secure the outer ring to the middle ring in different ways. For example, in some embodiments when the outer and middle rings are made of plastic, they may be secured to each other with a reversible or non-reversible snap fit. In some embodiments, when the outer and middle rings are metallic, they may be assembled by interference or press fitting of the middle ring into the center of the outer ring. In other embodiments, there may be a thin bearing between the two rings, the bearing having a shape suitable for joining the two rings. There may also be a bushing between the outer and middle rings to assist in the rotational freedom of the outer and middle rings. As noted, a lock ring may be used. In other embodiments. The lock ring may have a highly defined profile for snap fitting into the outer and middle rings and joining them. In yet additional embodiments, the lock ring may be metallic, providing a press fit or interference fit for the outer and middle rings. 
         [0057]    Details of one embodiment of the inner ring  16  are disclosed in  FIGS. 11-12 . Inner ring  16  includes an outer surface  112  for mating with an outer surface of middle ring  14 , and also includes an inner surface  114 , typically used for a user&#39;s finger. Outer surface  112  includes a hinge mount  18  with a hollow  116  for use with a lock pin  118 . In practice, the lock pin is assembled into the hollow  116  with ends of the lock pin  118  protruding from the hinge mount  18 . The ends of the pin rest in the hollow  96  of middle ring  14  on opposite sides of the gap  98 . Recall that gap  98  is the area occupied by the hinge mount  18  when the attachment device  10  is assembled. The inner ring  16  thus hinges on the lock pin  118  which hinges on the hinge mount  18 , supported by the ends of the middle ring  14 . The arrangement works because the internal parts of the hinge are secured by middle ring  12 . In embodiments, the lock pin  118  may be a plurality of lengths and diameters. 
         [0058]    In embodiments, the outer ring may be affixed or adhered to the mobile device of the user. The middle ring is able to rotate a full 360-degrees about the outer ring. This rotational freedom allows a user to orient the device for use or convenience. For example, many user devices include a viewing screen, a physical keyboard or a touch-screen keyboard, and a plurality of buttons with which to manipulate or operate the device. The ability to rotate the attachment device allows the user great freedom to orient and manipulate the device. For example, the screen orientation relative to the user may be altered, from portrait to landscape, by using the swivel motion of the attachment device to rotate the device to which it is attached. 
         [0059]    An exploded view of one embodiment is disclosed in  FIG. 13 . The attachment device  10  includes an outer ring  12  with a backing plate  78 , outer and inner surfaces  72 ,  74  and an internal hollow  76 . Outer ring  12  is locked to middle ring  14  via lock ring  99 . Middle ring  14  is disclosed with an inner surface  92 , an outer surface  94  and an external hollow  96  and gap  98  on the outer surface. Lock ring  99  occupies the hollows  76 ,  96  to lock the rings together. Inner ring  16  includes an outer surface  112  and an inner surface  114  for accommodating a finger of a user. Inner ring  16  is assembled to middle ring  14  via hinge mount  18  and lock pin  118 , which fits into hollow  116  of the hinge mount  18 . Hinge mount  18  fits into the gap  98  of the middle ring, as described above. 
         [0060]    The attachment device as disclosed herein has many advantages. The device includes many convenient features for the mobile device to which it is affixed. First and foremost it is designed to function as a “ring” that slides over a user&#39;s finger, or other means of holding a device, such as a device stand, allowing secure and confident holding of the mobile device via the attachment device. This ring is unique in that the outer ring allows 360-degree swivel of the middle ring (and inner ring based upon the inner ring being secured to the middle ring). The functionality can be separated into several distinct states. In an open state, the attachment device has several functions, and is not limited to these alone. The device acts as a ring to be used with the user&#39;s finger, or device stand, to hold the mobile device or other user device. This allows for mobile device to be firmly grasped, reducing the chance of dropping the device without the need of grasping with more than one finger. The attachment device allows the user to hold a mobile device with one finger, away from the user&#39;s palm, freeing the remainder of the hand to do other tasks. In a position in which the inner ring is left at a fixed position, the attachment device may be used to hold the mobile device at a fixed angle for viewing, such as placement on a table surface where the attachment device holds the mobile device at a 45-degree angle relative to the plane of the tabletop. 
         [0061]    In the closed state, there are also many possible applications for the attachment device. For example, with the inner ring in a closed position and the device in a flat orientation, such as seen in  FIG. 5 , the attachment device may form a one finger gripping point that reduces the mobile device from sliding out of a user&#39;s hand. The device may also act as a spacer of buffer between the back of the user device and any surface the device is placed upon. This protects the finish of the mobile device by keeping it away from direct contact with a possible rough or damaging surface. The flat surface, or closed top of the attachment device, again, as seen for example in  FIG. 5 , may also act as a clear flat surface to apply signage and branding for custom marketing. Because of the range of motion of the inner ring, the mobile device may be easily returned to a small holding compartment, such as a pocket or purse, with the ring in a closed, flat position without the user having to accommodate the bulk of the attachment device in its opened position. 
         [0062]    The concentric circular design disclosed herein provides a great deal of freedom for users of the disclosed device, in terms of ability to orient the device and the attachment. It is understood that the rings disclosed herein are intended to be used with actual objects and as such are only approximations of true circles. Such circular rings are able to rotate within each other. Rings of other shapes, such as ovals, will not rotate and will thus allow less freedom for the user. Many such non-rotating shapes, such as ovals, or even squares or rectangles, are still able to mount a hinge and support a lock pin. This may allow an oval, square or rectangular attachment to mount to a user device. The user may then open an inner ring, whether in a generally oval, square or rectangular shape, and use the inner shape to hold the user device. In these embodiments, an outer shape of the inner ring may be a non-rotatable shape, while providing for a generally circular inner shape or shapes to accommodate a user&#39;s finger or other object suitable for holding the user device. 
         [0063]    While the disclosure has been disclosed in connection with the preferred embodiments shown and described in detail, various modifications and improvements thereon will become readily apparent to those skilled in the art. Accordingly, the spirit and scope of the present disclosure is not to be limited by the foregoing examples, but is to be understood in the broadest sense allowable by law.
