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.

Claims

1. A mobile device charger, comprising:

a main body comprising a charging circuit configured to receive a line AC voltage and convert it to a DC voltage suitable for charging a mobile device, the main body having a main body plane; and

a pair of AC prongs foldable into the main body plane in a stowed position and configured to be pivoted out of the main body plane in an operable position, each of the AC prongs has a respective main body plane in their stowed positions, the AC prongs lie flattened out so that the main body planes of both said AC prongs extend in the same plane and parallel to the main body plane of the main body of the charger and said main body has a thickness dimension of less than 12 mm.

2. A mobile device charger, comprising:

a clip formed of a first clip body portion and a second body portion which are interconnected via a spring-biased clip and which provide an ability to be clipped to an article of clothing;

a charging circuit embedded in the clip and including AC prongs foldable into the body of the clip in a stowed position and configured to be pivoted out of the body portion in an operable position;

a cell phone hook on which the mobile device can be hooked, the hook having electrodes formed therein which are electrically coupled to the mobile device, whereby the clip provides the dual functionality of supporting mobile device and also enabling it to be inserted into an AC power source to charge the mobile device, and

wherein the charging circuit is embedded in the first body portion and the AC prongs are mounted to the second body portion.

3. The mobile device of claim 2, including the USB connector.

4. The mobile device of claim 2, in combination with a mobile device jacket which is configured to clip and hold onto a mobile device charger and which is provided with said mechanism that allows it to be hooked on the hook of the clip and to communicate the charging signals to the mobile device.

5. A mobile device, comprising:

a mobile device body housing holding therein communication circuits that enable a user of said mobile device to communicate wirelessly with other mobile devices or with a central communication system;

an internal battery in said mobile device housing for powering circuitry located within said mobile device housing;

a built-in charging circuit for said battery;

AC prongs stowed within said mobile device housing; and

an operating mechanism coupled to and configured to enable a user to selectively move said AC prongs in and out of said mobile device housing,

wherein said mobile device housing has a generally rectangular shape with length, width and thickness dimensions and defining a main body plane which is oriented perpendicular to said thickness direction of said housing and wherein said AC prongs have respective main body planes and the body planes of the AC prongs lie flattened out in the same plane and oriented parallel to the main body plane of the housing in a stowed orientation of said AC prongs, and said thickness dimension is less than 12 mm.
