Abstract
Abstract A protective cover for an electrical outlet is made up of a cover plate attachable to the existing receptacle plate and includes an opening aligned over each outlet in the plate and a unitary cap which is hinged to the cover along one side of each opening. The cap is movable into snap-fit engagement with a catch so as to serve as a protective cover over the outlet to prevent tampering and protect it from the elements. A latch release mechanism internally of the cap minimizes the risk of opening by infants as well as making it weatherproof.

Total Claims: 14
Claim 1
Independent Claim
224 words
A protective cover for electrical receptacles of the type having at least one electrical outlet for insertion of the prongs of an electrical plug, said cover comprising: an adapter plate including an exterior surface, an interior surface with an opening in said plate alignable over said outlet, and means for releasably connecting said adapter plate to said receptacle such that the opening therein is aligned with said outlet for exposing same; a catch member on the exterior surface of said plate alongside each opening; a generally convex cap member including means securing said cap member to said plate on one side of each opening opposite to said catch member for movement between an open position and a closed position, said cap member sized to substantially cover the opening when in the closed position and having latching means movable into releasable engagement with said catch member when said cap member is in the closed position; and release means extending from one end of said cap and member adjacent to said latching means across the interior of said cap and beneath an opening in said cap member, and a tool insertable through an opening in said cap member to depress said release means in a direction to exert an upward pressure on said latching means to release said latching means from engagement with said catch member.
Claim 2
Dependent Claim
224 words
