ABSTRACT:
A combination cover plate and safety guard plate to be interfaced with a conventional electrical wall receptacle to prevent a child of tender years from gaining unauthorized access to the receptacle and sustaining serious injury from an electric shock as a consequence of an accidental contact with a current carrying wire. The cover plate is adapted to receive one or more of the electrical receptacles, so that the power can be supplied therefrom to an electrical appliance, or the like. The cover plate and safety guard plate are pivotably interconnected with one another at first ends thereof. Each of the second ends of the cover plate and safety guard plate includes respective spring-biased retaining means by which the cover and safety guard plates can be releaseably connected together. Accordingly, the safety guard plate may be rotated towards the cover plate and secured in a position across the face thereof, whereby to cover the receptacles and prevent unauthorized access thereto. The safety guard plate may be rotated away from the cover plate by exerting sufficient force against the bias of a spring, whereby to permit the disconnection of the respective retaining means. The spring is selected so that the force required to disconnect the respective retaining means is greater than that which a child of tender years is capable of exerting.
