Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 384 words
A device for impeding an unauthorized individual from plugging an electric plug into an electric receptacle, the plug having a cord extending therefrom, said apparatus comprising: a container having an open end, a closed end opposite said open end, and a wall between said open end and said closed end, said wall having an outer surface and an inner surface, said container being capable of receiving said plug; a child proof cap; an open-ended slot in one of said container and said cap, said slot being sufficiently large to receive the cord for passage of the cord out of said container, and said slot being sufficiently small so as to prevent the plug from leaving said container through said slot; means on said container, complementary to said child proof cap, for engaging the child proof cap for selective attachment and removal of said child proof cap to and from said container, said open end of said container being closed by said cap when said means engages said cap; and capturing means, operable independently of said child proof cap, for selectively preventing removal of the plug from said container, said capturing means comprising first and second opposed apertures in said wall of said container, and a lock bar including a middle portion receivable in said opposed apertures, including a first end portion outside of said container, proximate said first aperture, when said middle portion is received in the opposed apertures, and including a second end portion outside of said container, proximate said second aperture, when said middle portion is received in the opposed apertures, said second portion having a hole therethrough for receiving a padlock, said opposed apertures being sized to receive said middle portion of said lock bar but not to pass said first end portion so the lock bar can be received in said apertures with the second end portion outside the wall of the container to accept a padlock through said hole, said lock bar and said inner surface of said container defining a space sufficiently large for the cord to pass through but not sufficiently large for the plug to pass through so as to retain the plug in said container; whereby the plug is selectively captured in said container by at least one of said cap and said capturing means.
Claim 2
Independent Claim 384 words
A device for impeding an unauthorized individual from plugging an electric plug into an electric receptacle, the plug having a cord extending therefrom, said apparatus comprising: a container having an open end, a closed end opposite said open end, and a wall between said open end and said closed end, said wall having an outer surface and an inner surface, said container being capable of receiving said plug; a child proof cap; an open-ended slot in one of said container and said cap, said slot being sufficiently large to receive the cord for passage of the cord out of said container, and said slot being sufficiently small so as to prevent the plug from leaving said container through said slot; means on said container, complementary to said child proof cap, for engaging the child proof cap for selective attachment and removal of said child proof cap to and from said container, said open end of said container being closed by said cap when said means engages said cap; and capturing means, operable independently of said child proof cap, for selectively preventing removal of the plug from said container, said capturing means comprising first and second opposed apertures in said wall of said container, and a lock bar including a middle portion receivable in said opposed apertures, including a first end portion outside of said container, proximate said first aperture, when said middle portion is received in the opposed apertures, and including a second end portion outside of said container, proximate said second aperture, when said middle portion is received in the opposed apertures, said second portion having a hole therethrough for receiving a padlock, said opposed apertures being sized to receive said middle portion of said lock bar but not to pass said first end portion so the lock bar can be received in said apertures with the second end portion outside the wall of the container to accept a padlock through said hole, said lock bar and said inner surface of said container defining a space sufficiently large for the cord to pass through but not sufficiently large for the plug to pass through so as to retain the plug in said container; whereby the plug is selectively captured in said container by at least one of said cap and said capturing means.
Claim 3
Independent Claim 346 words
A device for impeding an unauthorized individual from plugging an electric plug into an electric receptacle, the plug having a cord extending therefrom, said apparatus comprising: container means having an open end, said container being capable of receiving said plug; child proof cap means; an open-ended slot in one of said means, said slot being sufficiently large to receive the cord for passage of the cord out of said container, and said slot being sufficiently small so as to prevent the plug from leaving said container through said slot; means on said container, complementary to the child proof cap, for engaging the child proof cap for selective attachment and removal of the child proof cap to and from the container, said open end of said container being closed by said cap when said means on said container engages said cap; and second capturing means, operable independently of said child proof cap, for selectively preventing removal of the plug from said container, said second capturing means being engageable by a padlock to secure said second capturing means to said container, said second capturing means comprising a generally planar lock bar including a middle portion having a first width and a first end portion having a width wider than the width of said middle portion and including a second end portion having a hole therethrough for receiving a padlock, wherein said container has a generally cylindrical wall, opposed apertures in said wall having a width adequate to receive said middle portion of said lock bar but not to pass said first end portion so the lock bar can be mounted in said apertures with the second end portion outside the wall of the container to accept a padlock through said hole, said second capturing means further comprising a space defined by said lock bar and said container between said lock bar and the wall of said container having a maximum width which allows the cord to pass through the space but which does not allow the plug to pass so as to retain the plug in said container.
Claim 4
Independent Claim 346 words
A device for impeding an unauthorized individual from plugging an electric plug into an electric receptacle, the plug having a cord extending therefrom, said apparatus comprising: container means having an open end, said container being capable of receiving said plug; child proof cap means; an open-ended slot in one of said means, said slot being sufficiently large to receive the cord for passage of the cord out of said container, and said slot being sufficiently small so as to prevent the plug from leaving said container through said slot; means on said container, complementary to the child proof cap, for engaging the child proof cap for selective attachment and removal of the child proof cap to and from the container, said open end of said container being closed by said cap when said means on said container engages said cap; and second capturing means, operable independently of said child proof cap, for selectively preventing removal of the plug from said container, said second capturing means being engageable by a padlock to secure said second capturing means to said container, said second capturing means comprising a generally planar lock bar including a middle portion having a first width and a first end portion having a width wider than the width of said middle portion and including a second end portion having a hole therethrough for receiving a padlock, wherein said container has a generally cylindrical wall, opposed apertures in said wall having a width adequate to receive said middle portion of said lock bar but not to pass said first end portion so the lock bar can be mounted in said apertures with the second end portion outside the wall of the container to accept a padlock through said hole, said second capturing means further comprising a space defined by said lock bar and said container between said lock bar and the wall of said container having a maximum width which allows the cord to pass through the space but which does not allow the plug to pass so as to retain the plug in said container.
