Abstract
Abstract This invention consists of a device attachable to an electrical outlet and wall socket which will prevent babies and small children from pulling out the plug, inserting their fingers or other objects into the socket and onto the plug where they might receive a damaging electrical shock. In general the invention consists of an attachable receptacle plate with raised collars positioned upon the electrical wall outlet. A flexible split cap is positioned about the electrical cord and plug. The caps engage the collars in a locking relationship such that they can not be disengaged by a baby or small child. The caps attached to the collars by means of protruding stubs which are guided into tracks in the collars. In addition, flexible locking tab on the caps is forced inward when the cap is turned and pops outwardly in locking position through a hole in the collar. The cap can only be disengaged from the collar by pushing the locking tab inward and turning the cap. This can not be accomplished by a baby or infant, hence a small child is protected from shocking itself.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
173 words
An interchangeable protective device adapted for installation upon an electrical outlet, plug and cord connected thereto, comprising in combination: a receptacle plate having an electrical outlet thereon; a raised collar on said receptacle plate encircling said electrical outlet, said raised collar having: a tab slot extending longitudinally inward through said raised collar; a locking slot extending approximately perpendicular to said tab slot in a circumferential direction through the inner portion of said raised collar; a tab indentation extending from said locking slot to the outer surface of said raised collar; a split cap positioned about an electrical plug and cord, said split cap adapted for insertion within said raised collar; a flexible locking tab adapted for inward motion extending from the outer surface of said split cap, adapted to engage said tab slot and said locking slot, and to protrude through said tab indentation, said locking tab adapted to being unlocked when pressed inwardly; a flat surface positioned on said locking tab adapted to bear against said locking slot in a locking relationship.
Claim 2
Dependent Claim
173 words
An interchangeable protective device adapted for installation upon an electrical outlet, plug and cord connected thereto, comprising in combination: a receptacle plate having an electrical outlet thereon; a raised collar on said receptacle plate encircling said electrical outlet, said raised collar having: a tab slot extending longitudinally inward through said raised collar; a locking slot extending approximately perpendicular to said tab slot in a circumferential direction through the inner portion of said raised collar; a tab indentation extending from said locking slot to the outer surface of said raised collar; a split cap positioned about an electrical plug and cord, said split cap adapted for insertion within said raised collar; a flexible locking tab adapted for inward motion extending from the outer surface of said split cap, adapted to engage said tab slot and said locking slot, and to protrude through said tab indentation, said locking tab adapted to being unlocked when pressed inwardly; a flat surface positioned on said locking tab adapted to bear against said locking slot in a locking relationship.
