     FIELD OF THE INVENTION 
       [0002]    The present invention relates generally to a system and method for pivotally mounting an electronic device on a wall. The invention provides a wall mount and a back cover coupled to the device that enables the device to easily rotate about its position on the wall. 
       BACKGROUND 
       [0003]    In recent decades, many individuals have come to rely on electronic devices as their primary source of entertainment. This popularity has transformed these devices into thinner and lighter electronics that can be easily mounted or held in a user&#39;s hands. These new devices have also been designed to change orientation intuitively to allow for full rotation of the device. To create a more comfortable user experience, a large number of individuals prefer to mount these lighter devices on a wall. Many wall mounts have been designed for this purpose, but few allow for full rotation. The wall mounts that can provide full rotation are heavy, bulky, and unsightly. They can damage the wall they are mounted on and can be difficult to use. It is therefore advantageous to provide a light, easy to use, and unobtrusive wall mount that allows a device to fully rotate.

     DETAILED DESCRIPTION 
       [0072]    Embodiments of the wall mount  10  of the present invention preferably allow a display device  50  to be securely mounted on a wall in such a way that a user can easily rotate the device between vertical and horizontal orientations without losing continuous power to the device. The wall mount is secured to the wall on one end and interlocked into the display device on the other. The wall mount  10  is preferably 7.8 millimeters thick at its thickest point and 5.7 millimeters at its thinnest point with a 288 millimeter diameter. These measurements of the preferred embodiment with a thicker upper section and a narrower lower section are shown in  FIG. 4 . When coupled to the display device and mounted on a wall, the wall mount holds the device roughly 2.5 millimeters from the wall. The wall mount consists of four main components, a wall plate, a face plate, a rotator ring, and a power disc, as seen in  FIGS. 1 and 5 . The pieces of the wall mount are preferably Teflon coated to decrease friction, and can be made of various materials, although steel is preferred. 
         [0073]    The wall plate  20 , shown in  FIG. 6 , is closest to the wall and is a circular piece fastened into the wall&#39;s surface by screws or another fastening mechanism. In its center is a circular orifice  21  surrounded by a recessed circular edge in which the power disc  70  engages such that the wall plate, and the other wall mount  10  components, encircle the power disc  70 . The outer wall plate has slots  22  for screws or other tools such as double sided adhesive tape to mount and secure the wall mount to the wall, as well as recessed and projecting rings  23  at varying distances from the center for interacting with the other components of the wall mount. At least one of the indented rings will interact with the rotator ring  30  and has two stops  24  radially opposite each other to limit the range of rotation of the invention. 
         [0074]    The rotator ring  30 , shown in  FIG. 7 , is formed to be positioned over the outermost portions of the wall plate  20 . It is similarly a circular shape with a center circular orifice  31 . Preferably, the top of the rotator plate&#39;s outside edge has protruding mounting horns  32  that interlock with the back cover  80  of the display device  50  and hold the display device  50  in place when mounted on a wall  60 . The rotator ring also has extended segments  33  on its interior edge which interact with the stops on the wall plate to determine the range of rotation. 
         [0075]    Then the face plate  40  fits over the inner portion of the rotator ring  30  and engages with the wall plate  20  at a radial location approximately between the center wall plate&#39;s center and edge. It is also a circular shape with a center orifice  41 . The inner edge of the face plate is shaped to have large diameter arcs  42  forming slots that, when assembled, avoid covering the mounting slots  22  on the wall plate, as seen in  FIG. 9 . The inner edge of the face plate is also shaped to have smaller diameter arcs  43  with knife edges  45 . These smaller diameter arcs form tabs which will fit behind the back cover  80  of the device to secure the device when it is oriented horizontally, as in  FIG. 24 . The outer circle of the face plate also has slots  44  which match up with at least some of the mounting slots  22  on the wall plate  20  for joining the two components by screw or other device and effectively enclosing rotator ring  30  between the components. In preferred embodiments, the screw or other mechanism in slots  22  and  44  extend to the wall  60  and hold wall mount  10  in place on a wall or other surface. This embodiment is illustrated in  FIGS. 10A, 10B, 34A, 34B, 35A, and 35B . 
         [0076]    The power disc  70  sits in the center of the wall mount  10  as seen in  FIGS. 1, 34A, 35A , and  35 B and provides electricity to the display device. A detailed view of the power disc inside of the wall plate in one embodiment of the invention is shown in  FIG. 34B . The power disc is made up of five components: a main disc  71 , two contact pads  72 , wires  73 , a strain relief  74 , and a cover  75 . The main disc  71  is circular in shape with raised arcs that create a recessed compartment in the center of the main disc, as seen in  FIG. 27 . These arcs enclose and protect the electrical contact pads  72  which supply power to the device  50  and are preferably in the center of the main disc  71 . The main disc includes further protrusions that encircle the wires and strain relief and provide a foundation on which the cover piece  75  rests, creating a protected compartment where the wires  73  connect to the contact pads  72 . It also preferably includes a second recess for the insulated wires. In some embodiments the main disc further includes orifices for connecting the cover piece  75  via corresponding stakes on the cover piece  76 . The contact pads  72  are two metal plates, one positively charged and one negatively charged, that lay in recess on the face of the main disc as in  FIG. 31  and are preferably secured thereto with an adhesive. They are shaped to carry electricity to the center of the main disc  71 , preferably with arcs having a radius centered concentrically with the other components when assembled, which will accommodate for rotation of the display device&#39;s contact points as the device&#39;s orientation changes. The contact pads  72  may be made of any material that conducts electricity, although those that do so most efficiently and inexpensively, such as copper or aluminum, are preferred. They may be made from a sheet of metal having two holes positioned vertically near a lower edge as seen in  FIG. 30A . The upper holes will provide a structure to anchor the contact pads to the main disc  71  while the lower holes will provide a connection point for the wires  73 .  FIG. 30B  illustrates a sheet of metal that may then be cut to the preferred shape. Double sided tape is preferably secured to the back of the contact pads by peeling the backing of the tape. Wires  73  attached to the bottom of the contact pads preferably connect the pads to an electrical power source. The power source is in the form of electrical wire that is connected to the power disk by a connector (not shown) allowing for easy replacement of the electrical source. The wires  73  can be made of any conductive material. As seen in  FIG. 28A  the preferred embodiment uses standard two-wire cable. In the preferred embodiment, the wires of the two-wire cable are separated at the last 35 millimeters from the end using an Exacto-type knife. The wires are then stripped of insulation at the end 25 millimeters as seen in  FIG. 28B . The wires  73  should be insulated where possible, as in  FIG. 29A . Next, the strain relief  74  should be slipped over the end of the wires just past the point where the cable has been split. The preferred embodiment includes positive and negative markings on the strain relief which should align with the corresponding wires  73  as in  FIG. 29A . Once the positive and negative contact pads  72  are identified as in  FIG. 29B , the wires  73  may be passed through the lower holes in the ends of the contact pads and soldered into place. The lowest hole should be connected to wires  73  while the upper hole should be kept clear. The contact pads  72  should be secured flat on the face of the main disc via the strain relief. The contact pads are then placed on the main disc with the cable and strain relief as shown in  FIG. 31 . The insulated wires  73  should not pass beyond the recess of the main disc. The exposed wires must not contact each other. Once the assembly is well aligned, the wires  72  should be secured with a glue gun and a generous amount of hot glue as in  FIG. 32A . The placement of the glue is highlighted in  FIG. 32B . The glue will provide strain relief and keep the exposed wires separated and insulated from each other. Finally, a cover  75  with a series of stakes engages with the protrusions of the main disc  71  and encases the contact pads  72 , wires  73 , and strain relief  74  between the cover and the main disc  71 . The cover is preferably positioned before the hot glue hardens and secured in place preferably by melting stakes protruding from the cover  76  into the holes of the main disc  71  as illustrated in  FIG. 33B . 
         [0077]    Preferably, the display device  50  includes a back cover  80  which connects the device to the wall mount  10 . The back cover  80  is generally a steel plate with recesses, orifices, and protrusions which integrate the wall mount into its center. Specifically, the back cover  80  has slots  81  that interlock with the mounting horns  31  of the rotator ring  30 . These slots  81  are positioned in a way that the mounting horns  31  are at the top most points of the wall mount  10  when the display device  50  is in the vertical position. The back cover  80  also has two raised flaps  82  that are positioned to interlock with the smaller diameter arcs  43  of the face plate. The knife edges  45  of arcs  43  will slide under the flaps  82 . They are positioned so that one flap  82  is above the point of rotation and one flap  82  is below the point of rotation when the device is in the horizontal orientation to support the device in both directions. This design is illustrated in  FIG. 15 . Preferably, the slots and flaps are punched and stamped into sheet metal that forms the back cover  80 . As the device  50  and back cover  80  rotate, the flaps  82  will be moved to the sides of the point of rotation and thus will not interlock with the face plate when the device is in the vertical orientation. This movement is shown in  FIGS. 21-24  in which the wall plate is invisible. 
         [0078]    The device  50  is attached to the wall mount  10  in the vertical orientation by placing the device slightly above the wall mount. The user then lowers the device  50  onto the wall mount  10 , where the mounting horns  31  will be captured by the corresponding slots  81  on the back cover as the device  50  slides downward. The lower blades  45  will also partially engage with the flaps  82  in this position as seen in  FIG. 16 . The connection between mounting horns  31  and the slots  81  will hold the device to the wall, as in  FIG. 20 . A user can then rotate the device  50 , bringing it to a horizontal orientation, by simply pushing or pulling an edge or corner of the device. That action will move the device and rotate the back cover, sliding the raised flaps of the back cover along channels between the face plate  40  and the core of the wall plate  20  over the extended portions  43  and knife edges  45  of the face plate. Thus, in the horizontal orientation, the device  50  is supported by the flaps  82 , locked into the face plate  40  above and below which secures the device on the wall via the raised flaps rather than only the mounting horns. Thus, the slots  81  are engaged when the invention is mounted in the vertical orientation and flaps  82  are engaged when the invention is rotated into horizontal orientation.
