ABSTRACT:
FIELD OF THE INVENTION
This invention relates to household electrical installation devices and more particularly to safety covers for electrical outlets intended to prevent children from touching the live prongs of a plug or inserting an object into the terminals of an outlet.
BACKGROUND OF THE INVENTION
Disclosed in my earlier U.S. Pat. No. 4,981,439, which patent is incorporated in this specification by this reference, is a safety device for preventing children from touching the live prongs of a jack plugged into a household electrical outlet, or inserting an object into the terminal of the outlets. This prior art device comprise separate components including a cover that could be easily misplaced. The instant invention results from an attempt to provide a more convenient, one-piece safety device which can also stabilize the position of a jack or plug connected to the outlet.
SUMMARY OF THE INVENTION
The principal and secondary objects of this invention are to provide a multi-function safety cover for electrical wall outlets which in an open position provides easy access to the outlet, and, in a closed position prevents access to the outlet when not in use, and stabilizes the position of a plug connected to the outlet by, among others, supporting the cord and preventing it from pulling down the plug.
These and other valuable objects are achieved by a safety cover including a base extending from a cover plate which can be substituted for the standard cover plate of the outlet, a pair of quarter-shell segments that are laterally hinged to the base and can be brought together to provide a complete enclosure of the outlet. Cut-outs in the edges of the segments allow for passage of the cord of the jack plugged into the outlet, a sleeve surrounding the base can be translated axially to lock the shell segments around the jack and cord.
