Description
Field of the Invention
This invention relates generally to protective covers for electric sockets and more particularly to a protective cover which is easily opened to permit installation and removal of electric plugs from the outlet and releasably locked to prevent tampering with the plug by a child.
Background of the Invention
Safety covers and shields for electric connections and sockets are well known in the prior art. However, most such shields or covers are not easily opened for use and do not have easily opened locking devices.

This invention differs from the above-cited prior art by providing a protective cover for electric sockets which consists of a base plate having openings to fit the individual electric receptacles and an opening to receive the mounting screw to secure the base plate in place of the usual socket cover plate. A box-shaped cover is hingedly connected on one side of the base plate and is opened to permit installation and removal of electric plugs in said receptacles. The box-shaped cover has slots extending along the side and top thereof through which the cords may extend from the plugs secured in said electric receptacles. The base plate and box-shaped cover have matching fasteners to secure the cover against being easily opened by a child. The hinged connection of the cover to the base plate may be separate hinge members pivotally secured together or may be a one-piece flexible hinge of the type known as a "living" hinge.

Brief Description of the Drawings
FIG. 1 is an isometric view of a protective cover for electric sockets installed in place in open position illustrating a preferred embodiment of the invention.
FIG. 2 is a view in side elevation of the protective cover shown in FIG. 1 in closed position.
FIG. 3 is a plan view of the protective cover shown in FIG. 1 in closed position.
FIG. 4 is a partial, isometric view, similar to FIG. 1, of a protective cover for electric sockets installed in place in open position illustrating an alternate embodiment of the invention using a different hinge for the cover.
Description of the Preferred Embodiment
Referring to the drawings by numerals of reference, there is shown in FIG. 1 an isometric view of an insulated, protective cover assembly 10 for electric sockets illustrating a preferred embodiment of this invention.
Protective cover assembly 10 comprises a base plate 11, of an insulating material such as plastic, hard rubber, etc., having openings 12 to fit the individual electric receptacles 13 and an opening 14 receiving the mounting screw 15 to secure the base plate in place of the usual socket cover plate. A box-shaped cover 16, of an insulating material such as plastic, hard rubber, etc., is hingedly connected, as at 17, on one side of the base plate 11 and is opened to permit installation and removal of electric plugs 18 in receptacles 13. The insulated, box-shaped cover 16 has slots 19, 20 extending along the side and top thereof through which the cords 21 may extend from the plugs 18 secured in electric receptacles 13. The insulated, base plate 11 and box-shaped cover 16 have matching fasteners 22, 23 to secure the cover 16 against being easily opened by a child. Fasteners 22, 23 are tubular, similar to a hinge, and are aligned when closed to receive a locking pin 24. The hinged connection 17 of the cover 16 to the base plate 11 may be separate hinge members 25, 26 pivotally secured together by a hinge pin 27 (FIGS. 1, 2 and 3) or may be a one-piece flexible hinge 28 of the type known as a "living" hinge (FIG. 4).
Operation
While the assembly and operation of this invention should be apparent from the foregoing description, a brief description of assembly and operation will be given for a clearer understanding of the invention and its function.
As previously described, the protective cover assembly 10 is preferably of electrically insulating materials such as plastic, hard rubber, etc. Cover base plate 11 is positioned on a surface in which the electric sockets are located with openings 12 positioned over electric receptacles 13. Hole 14 is positioned over the threaded mounting hole used in securing the usual cover plate in place and screw 15 inserted and tightened to secure the protective cover base plate in place.
In the view shown in FIG. 1, the box-shaped cover 16 is hinged open. Either form of hinge 17, as in FIG. 1 or FIG. 4, may be used. Electric plugs 18 are inserted in receptacles 13 and box-shaped cover 16 closed with the electric cords 21 extending from plugs 18 through the slots 19, 20 which permit free movement of the cords to the side or front of the cover assembly 10. With the cover assembly 10 closed, pin 24 is inserted in aligned locking tubes 22, 23 to secure cover 16 in a removably locked position.
While this invention has been fully and completely described, with reference to two preferred embodiments, it should be understood that, within the scope of the appended claims, the invention may be practiced otherwise than as specifically described herein.
