Abstract
An electrically nonconductive utility cable guard for use in protecting electrical riser cables from vandalism and rodent damage. The cable guard is a U-shaped open-ended channel formed of a reinforced synthetic resin material having an overall thickness of from 1/4" to 5/8". Molded to the outer edge of each side portion of the channel are short mounting tabs having apertures therein for mounting the guard to an accommodating surface such as a utility pole. In one embodiment the tabs extend from the side walls at an angle of 105.degree.. The cable guard neatly mates with underground conduit extensions due to a novel footing integrally molded to one end of the channel. The footing uses a plurality of stepped lips extending axially and radially away from the channel to mate with the ends of conduit of various sizes.
Claims12
An electrically non-conductive utility cable riser guard for use in connection with an above ground structure, said guard comprising:
- a channel-shaped open-ended elongated body having a rounded bottom portion and two side-wall portions, said body being composed of a glass fiber reinforced synthetic resin material having an overall thickness greater than 1/4";
- attachment means for securing said body to an above ground structure, said attachment means comprising a plurality of flat tabs integral to and extending from the outer edge of each side-wall portion;
- and
- a stepped footing integrally molded to one end of said body and comprising a plurality of concentric steps extending longitudinally from said body for mating with electrical conduits of different diameters.
An electrically non-conductive utility cable guard comprising:
- a substantially U-shaped open-ended channel having a rounded bottom portion and two side portions, said channel being formed of a glass-fiber reinforced polyester synthetic resin material having an overall thickness of from 1/4" to 5/8";
- means for mounting said channel to an accommodating surface, said means for mounting being integrally molded to and extending at an angle >90.degree. from the outer edge of each side portion and comprising a plurality of short flanges each having an aperture therethrough;
- means for axially interfacing one end of said channel with electrical conduit, said means for axially interfacing being integrally molded to one end of said channel and having a plurality of stepped lips extending axially and radially away from said channel.
A removable crush resistant electrically nonconductive utility cable guard for use in connection with an above ground structure for protecting above ground utility cables at the entry point to underground conduits, said guard comprising:
- a substantially U-shaped open-ended elongated body having a longitudinal axis and also having a rounded bottom portion and two side-wall portions, said body being composed of glass fiber reinforced synthetic resin material having an overall nominal thickness of 3/8";
- attachment tab means integrally molded to the outer edges of said side-wall portions at an obtuse angle and comprising at least two tabs on each side-wall portion positioned along the length of said elongated body at staggered locations, each of said tabs further comprising a perforation to accommodate a mounting bolt for securing said body to an above ground structure;
- and
- coupling means integral with said body at one end thereof and extending axially therefrom, said coupling means comprising a plurality of concentric steps aligned with said body for receiving during installation conduits of different diameters.
