Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
137 words
An electrical cable for undercarpet use comprising: (a) an elongated electrically conductive core surrounded by an electrically insulating jacket having a rectangular cross section including a top and a bottom, and (b) two elongated side members disposed on opposite sides of the jacketed core, each side member having a generally triangular cross section, including (i) a substantially flat bottom, substantially colinear with the bottom of the jacket and the substantially flat bottom of the other side member, (ii) a side, normal to its substantially flat bottom, which side is generally adjacent to the jacket and joined to the jacket by a longitudinal section that is adapted to be easily severed to separate the side member from the jacket, and (iii) a generally tapered top, which extends from the top of the side to the substantially flat bottom.
Claim 2
Dependent Claim
137 words
An electrical cable for undercarpet use comprising: (a) an elongated electrically conductive core surrounded by an electrically insulating jacket having a rectangular cross section including a top and a bottom, and (b) two elongated side members disposed on opposite sides of the jacketed core, each side member having a generally triangular cross section, including (i) a substantially flat bottom, substantially colinear with the bottom of the jacket and the substantially flat bottom of the other side member, (ii) a side, normal to its substantially flat bottom, which side is generally adjacent to the jacket and joined to the jacket by a longitudinal section that is adapted to be easily severed to separate the side member from the jacket, and (iii) a generally tapered top, which extends from the top of the side to the substantially flat bottom.
Claim 3
Dependent Claim
24 words
The cable of claim 1 in which each longitudinal section has a tapered cross section, with minimum thickness at its contact with the jacket.
Claim 4
Dependent Claim
31 words
The cable of claim 1 in which each longitudinal section has a substantially rectangular cross section, with the long dimension of the rectangle substantially parallel to the bottom of the jacket.
Claim 5
Dependent Claim
26 words
The cable of claim 1 in which the top of each side member joins the substantially flat bottom of the side member in a rounded vertex.
Claim 6
Dependent Claim
31 words
The cable of claim 1 further comprising an elongated rip cord embedded in the jacket in such a way that the jacket may be torn by pulling on the rip cord.
Claim 7
Dependent Claim
26 words
The cable of claim 1 in which the core comprises a central conductor, surrounded by a conductive shield, from which it is separated by a dielectric.
Claim 8
Dependent Claim
25 words
The cable of claim 6 further comprising an elongated conductive drain wire, electrically connected to the shield and disposed substantially coplanar with the central conductor.
Claim 9
Dependent Claim
42 words
The cable of claim 7 further comprising an elongated rip cord, substantially coplanar with the central conductor and the drain wire and embedded in the jacket in such a way that the jacket may be torn by pulling on the rip cord.
