Description:
FIELD OF THE INVENTION 
     The present invention relates generally to enclosure systems for mobile devices and more particularly to providing a retractable casing system for a cellular phone. 
     BACKGROUND 
     Mobile devices have become ubiquitous in everyday life. As mobile capabilities permeate many traditional devices, new devices having cellular connectivity are improving their dimensional utility becoming more convenient for many users. Mobile devices including smart phones, cellular phones, geo-positional systems (GPS), tablets and notebooks are some examples of mobile devices that are used by various users, for business or personal use. With the advancement in the technological capabilities and complexities of mobile devices, the need to provide physical protection to one&#39;s mobile device, protecting it from impact, damage, environmental and/or other physical adversity, is also increasing. Additionally, with the proliferation of mobile devices, users may also seek to distinguish their mobile device from another&#39;s by utilizing a casing or protection system which provides for unique labeling, colors, shapes or other visual identifiers. 
     While various protective cases have been designed for some mobile phones, many of the case designs are difficult to use, lack convenience in utility and may have restrictions for users who have dexterity limitations or other physical limitations. Other case designs are not physically protective, such as those involving peels and flexible covers for the mobile phones. Still other case designs are often overly rigid for a normal user when it becomes challenging and difficult to remove a phone from a protective case. 
     Some objectives of a convenient and purposeful casing system for a mobile device are preferably that it should: a) provide convenience and ease in use; b) be convenient and reasonably straight-forward to situate the cell phone into; c) provide a secure and reliable fit to a secured cell phone; d) be convenient and reasonably straightforward to remove the cell phone readily without risk of damage to a user or the physical cell phone; and e) be provide reasonable protection to the cell phone. 
     Based on these objectives, most of the casing systems in the market today fall short of the suite of requirements. For instance, many existing cases provide a molded shell of which the cell phone is to be torque and/or twisted into; these movements and requirements often cause a user to difficulty, especially one with limited or affected hand flexibility and dexterity. Similarly, where a user has mis-fitted his cell phone into the case (i.e., where the cell phone has been inserted upside down such that the camera is not aligned with the camera hole in the case, for instance), a user is required to unseat his cell phone and re-situate it into the case the right way; during this process, a user may again be challenged, be possibly injured or inconvenienced, or damage the cell phone or the case in repositioning it. In other situations, where a user has a poorly crafted case or has frequently removed and replaced the cell phone into a case, often the cell phone&#39;s seating in the case is no longer secure and the cell phone may inadvertently be released from the case unexpectedly. The security of the seating of the cell phone is an integrity aspect which a user is dependent upon. 
     Further, the combined objectives of providing for a secure fit and being protective, also require that a case be able to withstand a reasonable drop height such that common impacts do not damage the cell phone or the case. These combined objectives are often in conflict with other combined objectives which provided for a good user experience, including convenience. For instance, in today&#39;s market, users often find that their experience provides for generally one or no more than two of the objectives above; user experiences are more likely to indicate that it is difficult to find a case which provides for being reasonably simple to put on, providing for an initially and repeatably secure fit, and providing for an simple removal technique. Typically, in the present market, if one casing system is very easy to put on and provides for a secure fit, it usually is very difficult to take off. Similarly, where a case is very easy to put on and easy to take off, it usually does not provide for a secure fit. 
       FIG. 1  shows an example of an existing case  10  for a mobile device. The existing case  10  depicts a case having two pieces with a top portion  11  for the upper end of a phone and a bottom portion  12  for the primary part of the phone. In operation, the top section  11  is seated against the bottom section  12 , and slides onto the bottom section  12  through the open side end. A cell phone (not shown) may be inserted into bottom section  12  and then the top section  11  may be slid onto the top section of the phone. Similarly, once the top section  11  is removed by sliding away from the bottom section  12 , the cell phone can be removed from the bottom portion  12 . 
     While the exemplar case of  FIG. 1  is more convenient than a traditional molded casing consisting of a unitary design, the exemplar case remains inconvenient and challenging for the reasons previously set forth above. For instance, the two-piece arrangement with a top section  11  and a bottom section  12  may inadvertently become separated where the resulting single piece becomes an ineffective case; additionally, during a normal impact, once of the portions may separate from the cell phone thereby leaving the cell phone unprotected; and further, the wearability of the two distinct pieces will occur at different rates if the user primarily removes the top portion. 
     It is therefore desirable to improve on cases and casing systems that are utilized to overcome the challenges set forth above. It is also desirable to provide for an improved unified casing system which may achieve the objectives discussed above and improve over the existing limitations. Therefore, it is advantageous to achieve a solution that overcomes the aforementioned issues.

     DETAILED DESCRIPTION 
     The following description is presented to enable one of ordinary skill in the art to make and use the embodiments of the invention and is provided in the context of a patent application and its requirements. Various modifications to the preferred embodiments and the generic principles and features described herein will be readily apparent to those skilled in the art. Thus, the present invention is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features described herein. 
     The present invention relates generally to enclosure systems for mobile devices and more particularly to providing a retractable casing system for a cellular phone having a unified operation. As set forth in  FIG. 2 , according to the current invention, six states of insertion operation ( 20 A- 20 F) and six states of removal operation ( 20 A- 20 F) for the present invention of the unified retractable casing system for a mobile device, are depicted. 
     From  FIG. 2 , a unified retractable casing system  20  for a mobile device  200  is depicted at cover-close state  20 A. The unified device is arranged to be configured as a single, unified retractable casing system which operates as though it was a single piece with flexible characteristics. In particular, though the device is comprised of a plurality of sub-assemblies and/or components, the resulting unified device generally has three main portions, as further depicted in  FIG. 2 : an upper cover  21  (see  20 A), a lower cover  22  (see  20 A), and a hinge mechanism  23  (see  20 B). The hinge mechanism  23  is present in the device of  20 A but is not visible as the upper cover  21  is situated as seated with the lower cover  22 , rendering the hinge mechanism to be no visible, in a preferred embodiment, from the perspective of  20 A. Further details of the hinge mechanism  23  are set forth below and with regard to  FIG. 3  and  FIG. 4 . 
     From  FIG. 2 , the six states of operation of the present invention are depicted. At  20 A, the present invention is arranged to be in the cover-close state, where the upper cover  21  and the lower cover  22  are arranged to be in contact with one another via the internal hinge mechanism  23  (not shown). At  20 A, the present invention is exclusive of a mobile device situated within. More particularly, the cover-close state can be visually determined by the contact point shown at  24  where the upper cover  21  and the lower cover  22  are in contact with one another, in a fully closed position, without a mobile device. In one or more preferred embodiments, when the upper cover  21  and the lower cover  22  are arranged to be completely in a closed position, the two parts form a seam in between along their respective edges when in contact. Operatively,  20 A depicts a close state for the present invention. 
     To operate the present invention from the cover-close state of  20 A to an insertion-pull-out state, as depicted at  20 B, the upper cover  21  is pulled outward from the lower cover  22  and thereby exposes, at least in part, the hinge mechanism  23 . This state is visually determinable as the insertion-pull-out state and may be visually inspected at  25 . In one or more preferred embodiments, the insertion-pull-out state may provide for arrangements of the device where the upper cover may be separated at varying distances from the lower cover, thereby visually allowing for portions or the entirety of the hinge mechanism to be observable. In such arrangements, these embodiments provide for the upper cover to be pulled away from the lower cover from a minimal distance to a maximum distance whereby the maximum separation as between the two portions is the maximal length of the insertion-pull-out state. 
     To operate the present invention from the insertion-pull-out state of  20 B to an insertion-bend-down state, as depicted at  20 C, the upper cover  21  is bent downward after being extended away from the lower cover  22 , thereby maintaining the exposure of the hinge mechanism visually, as visually set forth at  26 . In the insertion-bend-down state, the present invention is arranged to accept the insertion of a mobile device (shown as  200  in  20 D). 
     The present invention is operative to accept for insertion a mobile device  200  at  20 D, depicted as the inserted state, visually determinable at  27 . At this state, though the mobile device is inserted into the lower portion  22 , the mobile device is not fully seated nor secured with the present invention. Further steps are required in order to secure the inserted mobile device with the present invention. As used herein, the inserted state of  20 D may be used interchangeably with ‘removal state’ where a similar physical orientation of the present invention is required to remove the mobile device from the present invention, as further described herein. 
     Once the mobile device is inserted into the lower portion  22  of the present invention, the upper cover  21  is then operatively positioned to return to a position in which is aligned with the lower cover  22 ; in a preferred embodiment, the upper cover  21  is bent upwards towards its original position of  20 B, to achieve a insertion-bend-up state at  20 E, as is visually determinable at  28 . Once the upper cover is aligned with the lower cover, having first seated the mobile device within the lower cover, the combination of the present invention and the mobile device are ready to be securely seated. 
     At  20 F, the present invention is arranged from the bent-up state of  20 E to the device-secure state (also used herein as the insertion-push-down state or close state) of  20 F. To operate the device from  20 E to  20 F, in one or more preferred embodiments, first the upper cover  21  is aligned with the lower cover and the upper cover is pressed or pushed towards the lower cover. As the upper cover is pressed into contact with the lower cover, creating the seam described in  20 A though not visually viewable at  20 F due to the presence of the mobile device  200 , the mobile device is then secured and seated into the present invention. The upper cover  21  being arranged with the lower cover  22  is visually determinable at  29 . When the upper cover and lower cover are finally positioned in contact with one another with the mobile device within the present invention, the combination is complete and the mobile device is securable situated with the present invention (i.e., device-secure state or close state). Once the mobile device is situated with the present invention in the device-secure state, a user may securely use the mobile device or may then elect to remove the mobile device by returning to the removal-pull-out state or similar. 
     To remove the mobile device from the device-secure state of  20 F, the upper cover is pulled away from the lower cover, as in pull-out state  20 E. As soon as the removal-pull-out state  2 E reaches the maximal length, the upper cover can then be bent downward, as in removal-bend-down state  20 D. The mobile device accommodated and enclosed by the lower cover may then be readied to be removed from the casing system, as depicted at device-removal state  20 C; as used herein, the insert-device-on state  20 D is similar to a device-removal state  20 C in that the upper cover is bent downward from the axis of the mobile device for both actions where the physical state of the present invention appears similar for both activities. Once the mobile device is removed, the case may be bent-up as in  20 B removal-bend-up  20 B state, and pushed down and closed as in  20 A cover-close state (or removal-push-down state), or may remain open awaiting further mobile device insertion. 
       FIG. 3 , in accordance with one or more embodiments of the invention, sets forth a top view of the internal structure of the inner upper cover, inner lower cover, and the hinge mechanism of the present invention, in a state of any of cover-close  20 A, removal-push-down  20 A, device-secure  20 F, insertion-push-down  20 F.
