A cell phone charger comprises a main body having embedded therein a charging circuit configured to receive line AC voltage and to convert it to a DC voltage suitable for charging the mobile device. AC prongs fold into the body in a stowed position and a connection structure formed integrally with the main body grasps onto and holds the charger secured to the cell phone device. In a preferred embodiment, the AC prongs pivot independently and lie flat against an outside surface of the main body.

The present invention is generally directed to a battery charger and, more particularly, to a battery charger for cell phones and like mobile devices which is constructed to be detachably integrated with the body of the cell phone, with minimal alteration of the cell phone's weight and/or dimensions.
The present invention is rooted in the inspired realization by the present inventors that the explosive and unrelenting adoption by hundreds of millions, if not billions, of people of the cellular cell phone as the primary communication device, requires renewed focus on its charger circuitry and on the method and approach to charging cell phones, PDAs, and mobile communication devices generally.
Personal computing and communication devices such as the familiar cell phone, or the digital communication devices such as the famous Blackberry® and similar devices have been uniquely designed to be hand-held. They generally have a box-like, rectangular shape with a specific height, width and thickness dimensions that vary from device to device. The width of the typical cell phone is generally in the range from 4 to 7 centimeters or even 8 cm, with a height of approximately 10 cm and a thickness on the order of from 7 to 20 mm.
FIG. 1 is a perspective of a typical hand-held mobile communication device, illustrating its overall rectangular shape and comparative dimensions and component layout.
FIG. 2 is a back view of the mobile device of FIG. 1 with cover partially removed, exposing the internal battery and mechanism for attaching the cover.
FIG. 2A provides a view of the back side of the cell phone cover of FIG. 2.
With reference to FIG. 1, shown therein is a conventional, handheld mobile device 10, which may be any cell phone device, such as the now popular iPhone® line of phones, or the phones provided by the many other manufacturers in the field, including the Blackberry®. The communication device 10 of FIG. 1 has a generally rectangular shaped body 11 with dimensions as mentioned before and with a front panel featuring a display 12 and a keyboard 14. Of course, the device 10 may be of the type having a touchscreen, instead of a keyboard. Along the sides are various controls and connectors, including, for example, an audio output connector 16 and an interface circuit which also serves as a charging port 18, and various on/off switches 20 and other controls.
Turning to FIG. 2, in typical fashion, the mobile device 10 has a backside 22 with a removable panel or cover 24, which is typically released by pressing a release button 26, which allows the cover 24 to slide in grooved channels 28, 30, to expose a tightly packed compartment, including a battery 32. As is well known and also as shown in both FIG. 2 and FIG. 2A, the backside of the cover 24 has tongues 34 with catches 36, as well as a lock catch 38. When that cover 24 is placed facing down and in registrations with the slots 40 in the main body of the mobile device 10, it fits in and can slide until its catch 38 is caught and locked in the catch bar 27, which bar can be released by pressing the button 26.
Turning to FIG. 3, in order to avoid tampering with the mobile device 10 (and so possibly compromising warranties and/or to simplify its use), the invention provides a jacket style charger unit 50 which has the general configuration of a jacket with a back panel 52 which has a thickness of several millimeters and in which is embedded the charging circuit described below, or like charging circuits. The generally flat back panel 52 of the charger jacket 50 is flanked by left and right hugging panels 54, 56 which are inwardly curved, resilient and designed to either allow the mobile device 10 to be slid therebetween, or to be forcefully snapped onto the back side of the mobile device 10 and grasp and hold the side walls 13, 15 of the mobile device 10 (FIG. 1). To avoid blocking or obstructing access to the various controls typically found on the sidewalls 13, 15 and along the top of the mobile device 10, the resilient panels 54, 56 are largely cutout and have only several joining ribs for rigidity, which allow full access to the electrical connectors, switches and ports.
