DETAILED DESCRIPTION

(10) A conduit riser cover is indicated in the drawings by reference number 10. The cover 10 comprises a substantially cylindrical body 12 having a frusto-conical top segment 14. The body 12 defines a slit 16. There are opposed flanges 18 and 20 on each side of the slit. The cover 10 can be molded or otherwise constructed from a resilient, non-conductive material, such as a polymer or any other appropriate material. The nature of the material allows the cover 10 to be spread open at slit 16 as shown in FIG. 4 for mounting over the open end of a conduit riser C. It will be understood that the shape of the conduit riser cover 10 may be other than shown herein within the scope of the present invention. Although the cover can be beneficially employed with a conduit riser, it can be used to cover other electrical distribution equipment such as an insulated bushing of a transformer, cable terminator and the like.

(11) As seen in FIGS. 2 and 5, the top segment 14 includes an opening 22. The opening 22 is generally circular and is bounded by distal ends of a plurality of inwardly disposed members or fingers 24. The members or fingers 24 are flexible and allow the opening 22 to increase in size to accommodate different diameter electric wires W. Gaps between the fingers 24 form ventilation openings in addition to providing for flexing of the fingers. The top segment 14 also defines a separate plurality of ventilation openings 26 to allow airflow and the egress of hot air out of the cover.

(12) As seen in FIGS. 3 and 6, the body 12 includes a bottom opening 28. The opening 28 is bounded by distal ends of a plurality of inwardly disposed members or fingers 30. The members or fingers 30 are flexible and allow the opening 28 to conform to or fit on different diameter conduits (e.g., conduits in the inclusive range of from about 1.5 inches to about 5 inches in diameter).

(13) FIG. 7 illustrates the cover 10 installed over the upper opening of the conduit riser C. In installation, the cover 10 is opened at slit 16, as shown in FIG. 4, to encompass the wires W and the upper end of the conduit riser C. As noted previously herein, the flexible fingers 24 allow the cover 10 to encompass one or more wires W and seat snugly around the wires. As the conduit riser cover 10 is being applied to the conduit riser C, the electric wires W engage the fingers 24 and deflect them as required so that the wires may pass through the top of the conduit riser cover. The resiliency of the fingers 24 assures that while the size of the opening 22 may change, the ends of the fingers remain in engagement (or in a close spacing) to inhibit pests from accessing the conduit riser C. Similarly, the flexible fingers 30 can flex through engagement with the conduit riser C as the conduit riser cover is being applied to the conduit riser to change the size of the opening 28 and allow the cover to encompass the upper end of conduits of different diameters and seat snugly around the conduit. The finger 30 may flex to accommodate a typical range of conduit riser sizes of from about 1.5 to 5 inches. It will be understood that conduit risers outside of this size range may be accommodated by the fingers within the scope of the present invention. Thus, pests cannot access the conduit riser C open top by entering through the bottom of the conduit riser cover 10.

(14) As seen in FIG. 7, the cover 10 is locked in place by a slide 32 (broadly, “closure member”), which is shown in greater detail in FIG. 8. The slide 32 is configured for sliding down over the flanges 18 and 20 to secure them together to secure the slit closed. The slide 32 includes a substantially flat face plate 34, two perpendicular inner walls 36 and 38 that terminate at outwardly sloped ends 40, 42, respectively, that include securing openings 44 and 46, respectively. The walls 36 and 38 define a channel 48 that is dimensioned to seat the flanges 18 and 20. In this aspect, as seen in FIG. 4, the flanges 18 and 20 include securing openings 50, 52, 54, and 56. In the illustrated embodiment, the openings 44 and 46 align with the openings 52 and 56, and an additional securing means, such as a zip tie 58 can be threaded through the openings.

(15) It will be noted that in lieu of the slide 32, securing means can be introduced through the openings 50 and 54 and/or the openings 52 and 56. In addition to, or instead of, a securing means such as the zip tie 58 or the like, a tag or other identifying indicia can be attached to the cover through the holes in the flanges or the holes in the slide 32.

(16) As can be seen in the figures, when the cap 10 is mounted in place, there are a plurality of ventilation openings or gaps between the flexible upper fingers 24 and between the lower fingers 30, as well as ventilation openings 26. The ventilation openings allow airflow through the cover 10. The cover 10 prevents access by squirrels, birds, or other varmints into the upper open end the conduit riser C.

(17) It will be apparent that modifications and variations are possible without departing from the scope of the appended claims. It is intended that all matter contained in the above description and shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
