ABSTRACT:
A retractor device is mounted a recreational vehicle for permitting powered retraction of the external power cord. The power cord is normally stored within an interior compartment and is accessible through an openable cover when extension of the power cord and connection to an external electrical power source is desired. A retractor device is mounted interiorly of the cover and has a pair of generally parallel but spaced rollers which are relatively spring urged toward one another for gripping the power cord therebetween. The rollers are synchronously driven in opposite rotational directions from a drive motor which, through a suitable control switch, is powered from a low voltage direct current source, such as the vehicle battery. At least one roller can be moved, in opposition to the springs, into a release position by a manually-actuated release element to effectively disengage the cord when manual extension of the power cord is desired.
