Abstract

This invention is a three-wire grounding electric adapter that is comprised of a body, a first end and a second end wherein said first end has a vertical planar face capable of detachably engaging a 3-wire electric cord, said second end has a second vertical planar face. The body has a switch that is mounted on said body for permitting said adapter to complete, or disrupt positive electrical current from electrical receptacle to an electric device of at least two electric contact blades. The blades are fixedly mounted in said second end and extending outwardly from said second vertical planar face for engaging in an electric outlet. A security screw for securing at least one blade of an electric device plug into said adapter locking at least one blade into the adapter.

Claims

1. A three-wire grounding electric adapter comprising:

(a) a body comprising a first end and a second end wherein said first end has a vertical planar face capable of detachably engaging a 3-wire electric cord, said second end has a second vertical planar face;

(b) a switch mounted on said body for permitting said adapter to complete or disrupt positive electrical current from electrical receptacle to an electric device;

(c) at least two electric contact blades fixedly mounted in said second end and extending outwardly from said second vertical planar face for engaging in an electric outlet;

(d) a security screw for securing at least one blade of an electric device plug into said adapter locking at least one blade into the adapter wherein said security screw has a head, a shaft and a tab for lockably engaging at least one blade from a cord of an electric device, and wherein said head has an indentation for receiving the blade of a security key tool having a shape which is selected from the group;

star, triangle, pentagon, octagon, a squiggle, and spiral; and

(e) wherein said adapter further comprising a strap secured to said casing for restraining the cord from the electrical device.

2. A three-wire grounding electric adapter comprising:

(a) a body comprising a first end and a second end wherein said first end has a vertical planar face capable of detachably engaging a 3-wire electric cord, said second end has a second vertical planar face;

(b) an electronically actuated switch mounted on said body for permitting said adapter to complete or disrupt positive electrical current from electrical receptacle to an electric device;

(c) at least two electric contact blades fixedly mounted in said second end and extending outwardly from said second vertical planar face for engaging in an electric outlet;

(d) a security screw for securing at least one blade of an electric device plug into said adapter locking at least one blade into the adapter;

(e) a power source connected to said electronically actuated switch; and

(f) wherein said adapter further comprises a strap secured to said casing for restraining the cord from the electrical device and an electronic on/off switching device by a “

keyed”

mechanism or an electronic on/off switching device by a remote controlled on/off device.

3. The adapter of claim 2, wherein said power source is a battery.
