ABSTRACT:
A collapsible prong plug device includes a casing, an electrical plug with one or more prongs rotatably mounted in the casing and movable between a collapsed and an extended position, a securing means designed to engage the electrical plug to maintain the plug in an extended position, and a releasable securing means. The securing means can be released by a user to allow the plug to be moved to the collapsed position. A preferred form of securing mechanism is a spring and a preferred form of release means is a slidable collapse bar, designed to engage and rotate the prongs.
A cradle or attachment means can be integrated into the casing, with an electrical connection and a mechanical connection so that a rechargeable battery or a device containing such a battery can be electrically and mechanically attached to the cradle. Alternatively, a cable can be fined with a power adapter plug and electrically connected to the basic device. A power supply within the casing allows the rechargeable device to be attached to the collapsible prong plug device and plugged directly into a wall socket.
