THROUGH ROOF CONNECTOR ASSEMBLY

Abstract

A through roof connector assembly for connecting an air termination conductor to a conducting rod through a roof of a structure while limiting water ingress into the roof. The through roof connector assembly includes a universal top, a threaded stud, a conduit connection component with an upper threaded tap hole and a lower threaded tap hole which do not meet to provide a completely weatherproof connection, and a conduit extending through a roof membrane when installed in the roof. The conduit has within a conducting rod, the conducting rod threaded the lower threaded tap hole of the conduit connection component. The air terminal also threads into the threaded stud. An o-ring is located between the conduit connection component and the conduit to provide a further weatherproof connection.

DETAILED DESCRIPTION

[0018] Referring now to the drawings for a better understanding of the present invention, a through roof connector assembly is indicated in FIG. 1 et seq. by reference numeral 1. The through roof connector assembly 1 is capped by a through roof connector indicated in FIG. 1 et seq. by reference numeral 10. As displayed in FIG. 1 et seq., the through roof connector 10 includes a universal top 35, a threaded stud 50, and a conduit connection component 40. The through roof connector assembly 1, in addition to the universal top 35, threaded stud 50, and conduit connection component 40, also includes a conduit 75, a conducting rod 80, a nut 25, a washer 30, and an o-ring 60, each of which will be described in greater detail hereafter. Also displayed in FIG. 1 et seq. is a roof membrane 70 for maintaining a weatherproof seal around a roof 95. The threaded stud 50 may be one-half inch, one inch, or one and one-half inch in length. The universal top 35 has a roughly central through hole 37 to facilitate attachment to the threaded stud 50. The threaded stud 50 passes through the universal top 35 into an upper threaded tap hole 43 of the conduit connection component 40. In an embodiment of the invention, the roughly central through hole 37 may be threaded to accept threading of the threaded stud 50, and thereby attached the universal top 35. The connection between threaded stud 50 and upper threaded tap hole 43 may be secured with a thread-locking compound such as Loctite® adhesive. The nut 25 (such as a hex nut) and washer 30 (such as a spring washer) may also be used to hold threaded stud 50 in place. The nut 25, washer 30, and threaded stud 50 may be one-quarter inch UNC and may be composed of stainless steel, including 18-8 grade, such as 304 alloy or an alloy of copper.

[0019] The conduit connection component 40 has the upper threaded tap hole 43 and a lower threaded tap hole 45. Significantly, the upper threaded tap hole 43 and lower threaded tap hole 45 do not meet through the conduit connection component 40 so as to maintain the weatherproof resistance of the conduit connection component 40. The conduit connection component 40 is therefore solid material and presents at this junction no o-rings, gaskets, or seals to fail, thus maintaining the water tightness of the presently disclosed invention. The conduit 75 attaches to the conduit connection component 40. The conduit may be plastic pipe (such as PVC pipe) with a nominal bore of less than one-half inch, three-quarters inch, one inch, one and one-quarter inches, one and one-half inches, two inches, two and one-half inches, or larger.

[0020] The roof membrane 70 is also shown. The conduit 75 extends through the roof membrane 70 and roof 95 of a structure and provides a weatherproof seal between the roof 95, roof membrane 70, and the outside of the conduit 75. The roof membrane 70 may be sealed to the roof 95 via mastic or sealant.

[0021] The conduit 75 has within the conducting rod 80 for conducting any lightning which may hit the air terminal 15 via a wire into a grounding wire, grounding spike, etc. The conducting rod 80 is threaded into the lower threaded tap hole 45 of the conduit connection component 40 such as via a one-half inch UNC thread and may be composed of stainless steel and one-half inch in diameter.

[0022] The universal top 35, conduit connection component 40, or other parts discussed herein may be stamped from an aluminum alloy with a minimum of 90% aluminum or a copper alloy with a minimum of 60% copper or cast or forged from an aluminum alloy with a minimum of 85% aluminum or a copper alloy with a minimum of 80% copper. Any part made of copper alloy may be tin-plated or not.

[0023] In order to further increase the resistance to water of the presently disclosed invention, the conduit connection component 40 also has an o-ring indent for receiving an o-ring 60. The o-ring 60 located between the conduit connection component 40 and the conduit 75. The o-ring 60 may be composed of a suitable natural or synthetic rubber, in an embodiment of the invention. The o-ring 60 may be 3/16, 7/32, ¼, 5/16, ⅜, or 7/16 of an inch in thickness, or any other standard size. Note also the conduit 75 is recessed into o-ring indent of the conduit connection component 40 to further increase the resistance to water, based upon the usual orientation of the through roof connector 10.

[0024] In view of the above, it will be seen that the several objects of the invention are achieved and other advantageous results attained. As various changes could be made in the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description shall be interpreted as illustrative and not in a limiting sense.
