Abstract
The cord winding device of the present invention includes a housing within which a spring biased spool is engaged. The biasing spring is internal of the spool, creating a simple device which is small in size. Engagement of the spool to the housing is created with a yoke-like structure, allowing the device to function without regard to its orientation. The spool is provided with a high walled helical channel in its outer surface, within which a single layer of cord can be secured with turns of the cord being isolated from one another. The cord is pinched in position when placed at a severe angle from its coiled angle. Further, a double contact rotary contact assembly which is able to accommodate up to eight conductors is provided within the housing, creating devices by which current can be transferred from conductors of a fixed in position terminal end cord to conductors of the cord rotatably secured to the spool within the device without causing twisting of the cord.
