Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
139 words
A safety device for an electrical connector device of an electrical wall fixture, said safety device comprising a plate for covering an electrical wall fixture; a first externally threaded substantially sleeve type device mounted on the plate and surrounding at least part of an electrical connector device of the electrical wall fixture; a second externally threaded substantially sleeve type device mounted on the plate; a first internally threaded cap threadedly coupled to the first sleeve type device and covering the electrical connector device when the receptacle is not in use and threadedly coupled to the second sleeve type device when the receptacle is in use; and a second internally threaded cap for accommodating an electrical connector plug and threadedly coupled to the first sleeve type device when the receptacle is in use in cooperation with the electrical connector plug.
Claim 2
Dependent Claim
139 words
A safety device for an electrical connector device of an electrical wall fixture, said safety device comprising a plate for covering an electrical wall fixture; a first externally threaded substantially sleeve type device mounted on the plate and surrounding at least part of an electrical connector device of the electrical wall fixture; a second externally threaded substantially sleeve type device mounted on the plate; a first internally threaded cap threadedly coupled to the first sleeve type device and covering the electrical connector device when the receptacle is not in use and threadedly coupled to the second sleeve type device when the receptacle is in use; and a second internally threaded cap for accommodating an electrical connector plug and threadedly coupled to the first sleeve type device when the receptacle is in use in cooperation with the electrical connector plug.
Claim 3
Dependent Claim
27 words
A safety device as claimed in claim 1, wherein the sleeve type device comprises a substantially hollow cylinder having a cylindrical surface extending approximately 270° in circumference.
Claim 4
Dependent Claim
67 words
A safety device as claimed in claim 2, wherein the electrical connector device is a wall receptacle for accommodating an electrical connector plug affixed to electrically conductive wires, and wherein the second cap has a substantially axial bore formed therethrough and the wires extend through the bore, said second cap being funnel shaped and being threadedly coupled to the sleeve type device and accommodating the plug firmly.
Claim 5
Dependent Claim
116 words
A safety device for an electrical connector device of an electrical wall switch, said safety device comprising a plate for covering an electrical wall switch; a first externally threaded substantially sleeve type device mounted on the plate and surrounding at least part of the electrical wall switch, said sleeve type device comprising a substantially hollow cylinder having a cylindrical surface extending approximately 270° in circumference; a second externally threaded substantially sleeve type device mounted on the plate; and an internally threaded cap threadedly coupled to the first sleeve type device and covering the wall switch when said switch is not in use and threadedly coupled to the second sleeve type device when switch is in use.
Claim 6
Dependent Claim
116 words
A safety device for an electrical connector device of an electrical wall switch, said safety device comprising a plate for covering an electrical wall switch; a first externally threaded substantially sleeve type device mounted on the plate and surrounding at least part of the electrical wall switch, said sleeve type device comprising a substantially hollow cylinder having a cylindrical surface extending approximately 270° in circumference; a second externally threaded substantially sleeve type device mounted on the plate; and an internally threaded cap threadedly coupled to the first sleeve type device and covering the wall switch when said switch is not in use and threadedly coupled to the second sleeve type device when switch is in use.
