Abstract
A housing device for the retractable storage of a wire, cord or cable which is capable of operationally interconnecting electronic equipment, such as portable speakers and radios, while the interiorly coiled end of the wire, cord or cable remains coiled around a rotatable spool during connection. In its preferred embodiment, the housing device has a cover with connection ports therethrough. A radio connected to the connection ports becomes operationally connected with the interiorly coiled end of the wire, cord or cable through electrically conductive means integral with the spring-driven spool. The outer end of the coiled wire is then extended through an opening in the housing cover and connected to a portable speaker. The opening in the housing would be just large enough to accommodate the wire. A device larger in diameter than the wire would be attached at the near end of the exposed wire to prevent it from retracting all the way back inside the housing. After disconnection from the speaker, a light tug on the outer end of the coiled wire engages the spring-activated spool to retract the outer end back into the housing.
