ABSTRACT:
A safety cover for covering a plurality of co-planar sockets of an electrical outlet includes a plurality of cover sections. Attached to each of the cover sections is at least one non-conductive prong configured for insertion into at least one receptacle opening of one of the sockets. A flexible interconnection strip interconnects at least a first of the cover sections with at least a second of the cover sections. The flexible interconnection strip has a rest configuration in which the flexible interconnection strip is positioned in a manner such that the first and second cover sections are substantially non-coplanar with respect to each other. A cam structure is attached to at least one of the cover sections. The cam structure and the prong are located on the same surface of the cover section. The cam structure is constructed and positioned to permit a user to apply downward pressure on the surface of the cover section that is opposite to the cam structure while the prong is located in the receptacle opening and thereby to cause the cover section to pivot about the cam structure and to cause the prong to withdraw at least partially from the receptacle opening. As an alternative to the cam structure, the cover sections may be constructed of soft, elastic material. The outer edges of each cover section form a seal around the socket while the prong is located in the receptacle opening and no pressure is applied to the center portion of the cover section. The outer edges of the cover section push outward from the socket when pressure is applied to the center portion.
