1. An electrical charger for a mobile device, the charger comprising:
- a main body that is jacket-shaped and includes a back panel having a thickness of less than 12 mm, a left panel, a right panel and a bottom panel defining therebetween a space for receiving and holding the mobile device therein, said back panel housing a charging circuit configured to receive a line AC voltage and convert it to a DC voltage suitable for charging the mobile device;
a pair of AC prongs including a first AC prong and a second prong, selectively foldable into the back panel into a stowed position and into an extended position, at which the AC prongs jutt out of the back panel;
a connection structure comprising at least said left panel and said right panel and configured to grasp onto and hold the charger secured directly to the mobile device in a detachable manner; and
the AC prongs are so foldable into the back panel that in their stowed position, the main body plane of each of the prongs is aligned with a main body plane of the back panel,wherein the operating element is structurally formed as a slidable cover which exposes the AC prongs in a first sliding position and covers the AC prongs in a second sliding position of the operating element, the slidable cover including a first slidable cover for the first prong and a second and physically separate slidable cover for the second prong.

Abstract
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. In a further embodiment, the AC prongs are concealed by a cover plate in their stowed position.

10. The electric charger for a mobile device, the charger comprising:
-
a main body housing a charging circuit configured to receive a line AC voltage and convert it to a DC voltage suitable for charging a battery of the mobile device; a pair of AC prongs selectively foldable into the main body into a stowed position and into an extended position, at which the AC prongs jutt out of the main body; a connection structure configured to grasp onto and hold the charger secured directly to the mobile device in a detachable manner; and a cover structured and configured to conceal the AC prongs to render them invisible in the stowed position, including an operating element actuatable by a user of the charger and configured to raise the AC prongs from the stowed position and to return the AC prongs to the stowed position, in a manner wherein the pivotable movement of the AC prongs in and out of the main body is substantially proportional to the movement of the operating element, wherein each prong has a respective pivot body, and a tight wire is wound on by each said pivot body and said operating element pushes and pulls on said tight wire to move said prongs from and to said stowed position. - View Dependent Claims (11)
