Safety plug

Claim 2

A safety electrical plug comprising an insulating body, a pair of spaced elongate flat contact blades rotationally mounted in the body and extending therefrom for engagement with a socket type electrical outlet, contact means for connecting the blades to the conductors of a line cord, and drive means for rotating the blades about their longitudinal axes between a spaced parallel position for engagement with the socket outlet and a coplanar safety position, said drive means including biasing means urging the blades toward the safety position.

Claim 3

A safety electrical plug as in claim 1 including lock means for securing the blades in the safety position.

Claim 4

A safety electrical plug as in claim 1 wherein said drive means includes a slide on the body having a push button extending outwardly of the body, a rotational drive connection between said slide and one of said blades, and a rotational drive connection between said one blade and the other blade whereby the blades rotate together.

Claim 5

A safety electrical plug as in claim 3 including a lock member, engageable with said slide to lock the same in a given position.

Claim 6

A safety electrical plug including an insulating housing; a pair of blade assemblies in said housing; each assembly including a portion rotatably mounted in the body, a flat contact blade extending outwardly of the body, means for forming an electrical connection with a conductor, and a gear meshed with the gear of the other assembly; a slide on the body having a push button on one end thereof extending outwardly of the body; a rotational drive connection between said slide and one assembly; and a spring biasing said slide to extend the push button from the body whereby depression of the push button rotates said blades in one direction and the spring rotates the blades in another direction.

Claim 7

A safety electrical plug including an insulating housing; a pair of blade assemblies in said housing; each assembly including a portion rotatably mounted in the body, a flat contact blade extending outwardly of the body, means for forming an electrical connection with a conductor, and a gear meshed with the gear of the other assembly; a slide on the body having a push button on one end thereof extending outwardly of the body; a rotational drive connection between said slide and one assembly; and a spring biasing said slide to extend the push button from the body whereby depression of the push button rotates said blades in one direction and the spring rotates the blades in another direction.

Claim 8

A safety electrical plug as in claim 5 including lock means for limiting movement of the slide.

Claim 9

A safety electrical plug including an insulating housing; a pair of elongate flat blades extending from the housing; rotatable mounting means in the housing for one of said blades whereby the blade may be rotated relative to the housing; means for forming an electrical connection between the blades and the conductors of a line cord; drive means for rotating said one blade about its longitudinal axis between two positions, said drive means including biasing means urging such blade towaRd one of such positions; and lock means for holding such blade in such one position.

Claim 10

A safety electrical plug including an insulating housing; a pair of elongate flat blades extending from the housing; rotatable mounting means in the housing for one of said blades whereby the blade may be rotated relative to the housing; means for forming an electrical connection between the blades and the conductors of a line cord; drive means for rotating said one blade about its longitudinal axis between two positions, said drive means including biasing means urging such blade towaRd one of such positions; and lock means for holding such blade in such one position.
