Abstract
Abstract An ironing device includes an iron body having an electric heating element, a seat on which the iron can rest when not in use and a power supply cord terminating in a connector having a socket adapted to connect with prongs on the iron body for supplying power to the heating element. The connector is provided with a first releasable latch for detachably interlocking the connector with the iron body so that the iron can be used as a corded iron and a second releasable latch for detachably interlocking the connector to the seat so that the iron can be used as a cordless iron. The user can selectively interlock the connector to either the iron body or the seat by activating a button device on the seat which selectively releases either the first or second latch.
