Abstract
Abstract The invention relates to conduits for carrying and protecting cables and particularly to carrier supports within said conduits which support cables or other utility carriers. The carrier supports serve to protect the cables from abrasive contact with the conduit and comprise elongated extruded malleable members whose outer surfaces conform to the inner wall of the conduit. A plurality of extruded cavities are provided within the extruded member which are symmetrically oriented about a line central to the member, each cavity having a common wall along contact points between cavities and the outer covering of the extruded member. Support barriers are provided between the cavities and the outer walls to maintain the cavity form.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
136 words
A carrier support adapted to be within a protective conduit for the purpose of supporting utility carriers along a path in a damage-prone environment said carrier support comprising, a) an elongated extruded malleable member within and along said conduit path dimensionally disposed along its outer surface to conform to the inner wall of said conduit and carried thereby, b) a plurality of extruded individual cavities within said extruded member whose paths are "' symetrically oriented about a co-axial line central to said extruded member and each disposed to maintain a common wall along contact points between individual cavities and between cavity and outer covering of said extruded member, and c) support barriers within said extrusion between cavities and outer wall disposed to maintain the cavity form along the conduit path regardless of the damage prone environment.
Claim 2
Dependent Claim
136 words
A carrier support adapted to be within a protective conduit for the purpose of supporting utility carriers along a path in a damage-prone environment said carrier support comprising, a) an elongated extruded malleable member within and along said conduit path dimensionally disposed along its outer surface to conform to the inner wall of said conduit and carried thereby, b) a plurality of extruded individual cavities within said extruded member whose paths are "' symetrically oriented about a co-axial line central to said extruded member and each disposed to maintain a common wall along contact points between individual cavities and between cavity and outer covering of said extruded member, and c) support barriers within said extrusion between cavities and outer wall disposed to maintain the cavity form along the conduit path regardless of the damage prone environment.
Claim 3
Dependent Claim
52 words
A carrier support according to claim 1, in which the extruded member includes five cavities each having tangential contact along a common wall and contact with the outer wall to form three contact points to render stiffness and strength to the extruded member along its complete path to preveht the collapse thereof.
Claim 4
Dependent Claim
43 words
A carrier support according to claim 2, in which the cavities are circularly shaped to permit a common wall thickness between cavities and between cavity and outer wall to render maximum capacity within the extrusion while still maintaining the required stiffness and strength.
Claim 5
Dependent Claim
26 words
. A carrier support according to claim 2, in which the cavities are honey-comb shaped with common wall contact points to provide maximum size and strength.
Claim 6
Dependent Claim
34 words
A carrier support according to claim 1, in which there is included between the cavities and wall, filler spaces, each disposed to provide additional strength as well as means for transmitting additional utility functions.
Claim 7
Dependent Claim
45 words
A carrier support according to claim 1, in which the extruded member is triangular frustrum shaped to accomodate a plurality of cavities, said configuration disposed to permit the extruded member to freely coil and wind to accommodate and freely negotiate conduit paths having impediments therein.
Claim 8
Dependent Claim
51 words
A carrier support according to claim 6, in which triangular member includes three, five or more circularly configured cavities each having contact points along a common wall between the cavities and between cavity and the outer wall of the extruded member to provide optimum size and rigidity. to the extruded member.
Claim 9
Dependent Claim
48 words
A carrier support according to claim 6, in which the extruded member includes three honey-comb configured cavities, each having contact points along a common wall between cavities and between cavity and the outer wall of the extruded member to provide optimum size and rigidity to the extruded member.
Claim 10
Dependent Claim
39 words
A carrier support according to claim 1, in which the extruded member includes a plurality of cavities rectangularly arrayed within said member, the cavities having contact points along common barrier walls and the outer walls of said extruded member.
Claim 11
Dependent Claim
71 words
A protective conduit having therein an extruded malleable carrier support according to any one of the preceding claims, the inside surface of said conduit and the outside surface of said carrier support defining a space for receiving filler material disposed to solidify therein to cause the said conduit and carrier support to maintain a fixed spaced relationship to suitably protect the carrier support from the entry of contaminents within the conduit.
Claim 12
Dependent Claim
87 words
A cable support system comprising extrudable cable support members each composed of cable carrying cells symmetrically arrayed about a coaxial line central to the said array, resilient means connecting said cells to maintain and support the cells in their arrayed configuration while providing resiliency to the cell array configurations, material means disposed about the said cells to provide reinforcement and lubrication along their wear and/or bearing surfaces, and splicing means for connecting the cable support members at their extremities to maintain continuity of the cable support system.
Claim 13
Dependent Claim
87 words
