ABSTRACT:
An electrical outlet protective cover 10 is described for mounting to ungrounded or grounded electrical outlet receptacles for preventing a child from inserting a foreign object into the receptacle or from inserting an electrical plug. The cover 10 has a back plate 52 with receptacle apertures 68, 70 for receiving the receptacle. The cover has a front panel 54 substantially forward of the back plate 52 forming shutter cavities 56 therebetween. Shutters 60, 62 are slidably mounted in the cavities 56 for horizontal movement between offset positions and aligned positions. Each of the shutters 60,62 have slots or apertures 88, 90, 92 for receiving corresponding electrical plug progngs. The slots 88 and 90 are of an enlarged size to accommodate ungrounded prongs or grounded prongs. The cover 10 has plug passageways 76 and 78 aligned with the receptacle apertures 68 and 70 respectively for preventing a child from touching the prongs when a plug is being inserted into a receptacle. To insert a plug, one must first insert the prongs of the plug into the shutter slots while the shutter is in the offset position. Then lateral force must be exerted on the plug to move the shutter from the offset position to the aligned position. When the shutter is moved to the aligned position, the plug is clear to be inserted into the passageway 76, 78 and into the receptacle.
