Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
203 words
A locking wall plate and plug apparatus comprising, in combination, a mounting plate, the mounting plate including at least one annular opening, the annular opening including a rotatable outlet plate captured within the annular opening and rotatable from a first vertical position to a second vertical position, the rotatable outlet plate including a plurality of spaced parallel electrical prong receiving slots wherein the prong receiving slots are in a vertical orientation in the first position and in a vertical orientation in the second position mounted within the rotatable outlet plate, and an electrical plug member, the electrical plug member including a lock plate fixedly mounted to a forward end of the electrical plug member, and the electrical plug member including a plurality of locking legs orthogonally mounted and forwardly directed of the locking plate, and the locking legs spaced apart a predetermined diameter, and a plurality of electrical prongs mounted to the electrical plug member between the locking legs and directed forwardly of the lock plate, and the annular opening including a right and left annular locking slot wherein the locking legs are receivable within the locking slots in the second position and are displaced from the locking slots in the first position.
Claim 2
Dependent Claim
203 words
A locking wall plate and plug apparatus comprising, in combination, a mounting plate, the mounting plate including at least one annular opening, the annular opening including a rotatable outlet plate captured within the annular opening and rotatable from a first vertical position to a second vertical position, the rotatable outlet plate including a plurality of spaced parallel electrical prong receiving slots wherein the prong receiving slots are in a vertical orientation in the first position and in a vertical orientation in the second position mounted within the rotatable outlet plate, and an electrical plug member, the electrical plug member including a lock plate fixedly mounted to a forward end of the electrical plug member, and the electrical plug member including a plurality of locking legs orthogonally mounted and forwardly directed of the locking plate, and the locking legs spaced apart a predetermined diameter, and a plurality of electrical prongs mounted to the electrical plug member between the locking legs and directed forwardly of the lock plate, and the annular opening including a right and left annular locking slot wherein the locking legs are receivable within the locking slots in the second position and are displaced from the locking slots in the first position.
Claim 3
Dependent Claim
43 words
An apparatus as set forth in claim 1 wherein the locking slots are spaced apart a predetermined diameter and are defined by a predetermined arc of opening, and the locking legs defined a predetermined arc substantially equal to the predetermined arc of opening.
Claim 4
Dependent Claim
47 words
An apparatus as set forth in claim 2 wherein the locking legs each include an outwardly directed locking tab, wherein each locking tab and each locking leg are receivable within a respective locking slot when the rotatable outlet plate and plug member are in the second position.
Claim 5
Dependent Claim
55 words
An apparatus as set forth in claim 3 wherein the outlet plate includes a bifurcated end portion formed at opposed longitudinal sides of the outlet plate, wherein each bifurcated end portion captures and receives the mounting plate about the annular openings to position the outlet plate within the annular opening relative to the mounting plate.
Claim 6
Dependent Claim
76 words
An apparatus as set forth in claim 4 wherein the outlet plate includes an outlet plate biasing spring, the outlet plate biasing spring including a first end secured to the outlet plate and the second end secured to the mounting plate, and the biasing spring mounted within an annular track, wherein the biasing spring is arranged in a generally semi-annular configuration in a first position and stretched to a substantially annular configuration in the second position.
