Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 243 words
In an electrical outlet box having a wall structure providing front to rear wall means and a bottom wall interconnected therebetween, the front to rear wall means and bottom wall defining a chamber within the wall structure which opens through the front of the box, said wall means defining an outermost periphery of said box and including wall portions which are recessed inwardly from said periphery so as to define recessed areas extending along said periphery of said box, from the front to the rear of said box, said recessed areas housing cable entry port means for the passage of electrical power cable into said box chamber, said cable entry port means includes a generally rectangular aperture in said front to rear inwardly recessed wall portion extending upwardly from said bottom wall, a generally V-shaped opening in said bottom wall converging inwardly from the longitudinally extending side rims of said aperture and opening in a direction generally perpendicular to said front of said box, and closure panel means depending from the longitudinally extending side rims of said aperture and terminating in free end portions, said free end portions being separated by a distance which is less than the narrowest dimension of the electrical power cable to be inserted therein, said free end portions of said closure panel means adapted to deflect laterally away from one another upon passage of a cable into said aperture and to thereafter resistingly bear against the installed cable.
Claim 2
Dependent Claim 243 words
In an electrical outlet box having a wall structure providing front to rear wall means and a bottom wall interconnected therebetween, the front to rear wall means and bottom wall defining a chamber within the wall structure which opens through the front of the box, said wall means defining an outermost periphery of said box and including wall portions which are recessed inwardly from said periphery so as to define recessed areas extending along said periphery of said box, from the front to the rear of said box, said recessed areas housing cable entry port means for the passage of electrical power cable into said box chamber, said cable entry port means includes a generally rectangular aperture in said front to rear inwardly recessed wall portion extending upwardly from said bottom wall, a generally V-shaped opening in said bottom wall converging inwardly from the longitudinally extending side rims of said aperture and opening in a direction generally perpendicular to said front of said box, and closure panel means depending from the longitudinally extending side rims of said aperture and terminating in free end portions, said free end portions being separated by a distance which is less than the narrowest dimension of the electrical power cable to be inserted therein, said free end portions of said closure panel means adapted to deflect laterally away from one another upon passage of a cable into said aperture and to thereafter resistingly bear against the installed cable.
Claim 3
Dependent Claim 35 words
An electrical outlet box as claimed in claim 1, wherein said front to rear wall means includes a pair of opposed side walls and a pair of opposed end walls interconnected between said side walls.
Claim 4
Dependent Claim 19 words
An electrical outlet box as claimed in claim 2, wherein said recessed areas are formed in said end walls.
Claim 5
Dependent Claim 50 words
An electrical outlet box as claimed in claim 2, including electrical fixture mounting post members adjacent the inside surface of each opposed end wall in opposed alignment generally centrally of said end walls, and wherein each end wall is offset on either side of said electrical fixture mounting post member.
Claim 6
Dependent Claim 22 words
An electrical outlet box as claimed in claim 4, wherein said recessed areas in said end walls are in diagonally opposed alignment.
Claim 7
Dependent Claim 55 words
An electrical outlet box as claimed in claim 1, including a frangible closure web joining said free end portions of said closure panel means, substantially preventing access into said box through said cable entry port means, said frangible closure web being readily pierceable by manual force of the end of said electrical power cable thereagainst.
Claim 8
Dependent Claim 27 words
An electrical outlet box as claimed in claim 6, wherein said frangible web extends along the entire length of said free ends of said closure panel means.
Claim 9
Dependent Claim 75 words
An electrical outlet box as claimed in claim 1, including a third closure panel member extending inwardly from the inside surface of said front to rear inwardly recessed wall portion transversely of and closely adjacent to the converging front edges of said closure panel means, said third closure panel member thereby substantially closing the generally V-shaped space formed between said closure panel means which opens in a direction perpendicular to the front of the box.
Claim 10
Dependent Claim 36 words
An electrical outlet box as claimed in claim 8, including a reinforcing strut extending between the top of said third closure panel member and the inside surface of said front to rear inwardly recessed wall portion.
Claim 11
