Abstract

Abstract A protective fixture which is detachably mounted to existing wall plug receptacles comprising: a base member which overlies the plug receptacle face plate; a retention pin adapted to affix the base member to the receptacle; four essentially flat walls extending outwardly from the periphery of the plate member, at least one pair of studs affixed diametrically across on the inside face of each of the base plate side wall surfaces, a cover member having two essentially flat sides spaced apart and held spaced apart by a third front side, the vertical edges of the cover flat sides will abut in close proximity to the outwardly projecting vertical edges of the side walls, at least one pair of latching elements affixed diametrially across on the edge of the inside face of each side wall of the cover member and adapted to fit and detachably lock with the adjacent studs, when the said cover member is slipped into cooperative union with the base member.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 291 words
An electrical wall outlet protective fixture which is detachably mountable to an existing electrical plug receptacle comprising: (a) a rectangular back wall member configured to substantially overlie the plug receptacle; (b) a retention pin adapted to affix said back wall member to said receptacle; (c) four essentially flat walls extending outwardly from the periphery of said back wall member providing two opposing side walls, a top wall, extending outwardly from said back wall member a distance greater than said side walls and a bottom wall extending outwardly from said back wall member a distance greater than said side walls; (d) an open portion provided in said bottom wall and of a sufficient size to permit the passage of at least one electrical plug power cord; (e) at least one opening in said back wall member adapted to provide access to the receptacle sockets; (f) at least one pair of studs affixed one each on each inside face of said side walls at a location across from one another and protruding towards one another; (g) a separate cover member having two essentially flat sides spaced apart and held apart by a third front side sized so that the cover flat sides will abut in close proximity to the outwardly extending vertical edges of said side walls extending from said back wall member, and (h) at least one pair of latching elements affixed diametrically across on the edge of the inside face of each of said flat sides of the cover member and extending partially beyond thereof, said latching elements being adapted to fit and detachably lock with said paired studs, when the said cover member is slipped into cooperative union with said four flat walls extending outwardly from said back wall member.
Claim 2
Dependent Claim 291 words
An electrical wall outlet protective fixture which is detachably mountable to an existing electrical plug receptacle comprising: (a) a rectangular back wall member configured to substantially overlie the plug receptacle; (b) a retention pin adapted to affix said back wall member to said receptacle; (c) four essentially flat walls extending outwardly from the periphery of said back wall member providing two opposing side walls, a top wall, extending outwardly from said back wall member a distance greater than said side walls and a bottom wall extending outwardly from said back wall member a distance greater than said side walls; (d) an open portion provided in said bottom wall and of a sufficient size to permit the passage of at least one electrical plug power cord; (e) at least one opening in said back wall member adapted to provide access to the receptacle sockets; (f) at least one pair of studs affixed one each on each inside face of said side walls at a location across from one another and protruding towards one another; (g) a separate cover member having two essentially flat sides spaced apart and held apart by a third front side sized so that the cover flat sides will abut in close proximity to the outwardly extending vertical edges of said side walls extending from said back wall member, and (h) at least one pair of latching elements affixed diametrically across on the edge of the inside face of each of said flat sides of the cover member and extending partially beyond thereof, said latching elements being adapted to fit and detachably lock with said paired studs, when the said cover member is slipped into cooperative union with said four flat walls extending outwardly from said back wall member.
Claim 3
Dependent Claim 42 words
The protective fixture of claim 1 wherein the linear distance between the inside surface of said back wall member and said open portion of said bottom wall is less than the lateral distance required to pull a plug from an outlet receptacle.
Claim 4
Dependent Claim 21 words
The fixture of claim 1 wherein said fixture has an external configuration approximating the plug receptacle to which it is mated.
Claim 5
Dependent Claim 59 words
The fixture of claim 1 wherein each latching element comprises a hook-like element comprising a shank portion and an exterior portion projecting outwardly from said shank portion and at a right angle thereto and an outer oriented beveled leading edge to permit sliding contact with a stud until said exterior portion slips past the stud to lock with same.
Claim 6
Dependent Claim 27 words
The fixture of claim 1 wherein said cover member is removable under manual compression of the cover member flat sides permitting the breaking of said cooperative union.
Claim 7
Dependent Claim 20 words
The fixture of claim 1 wherein said cover member is of a rigid but mildly deformable plastic material of construction.
