Abstract
A roof jack adapter which allows standard roof jacks to be used in conjunction with the adapter for use on ribbed steel roofing. The roof jack adapter is comprised of a rectangular piece of steel flat bar strategically drilled to allow non abrasive elevators to be attached to the steel flat bar. The steel flat bar will also be drilled to allow the standard roof jack to be fastened to the adapter as well as the roof. The piece of steel flat bar will also have a support mechanism designed to allow the standard roof jack to be held securely on the roof jack adapter while the entire apparatus is being installed on the roof. The roof jack adapter with the non abrasive elevators will allow a standard roof jack to be fastened to a ribbed steel roof in a position above the rib portion of the steel roofing, thus not damaging the finish on the steel roofing.
Description

Fig. 2 shows the roof jack adapter 1 from a side view with the standard roof jack 7 the slot in the standard roof jack 9 the holes which allow the entire apparatus to be fastened to the roof 8 the slightly longer roofing screw 8A the support plank 7A the support mechanism 6 the non abrasive elevators 5 the screws securing the steel flat bar to the non abrasive elevators 4 and the piece of steel flat bar 10.
Fig. 3 shows the roof jack adapter 1 in place on a piece of steel rib roofing 12 with the non abrasive elevators 5 supporting the steel flat bar 10 with the standard roof jack 7 fastened through the hole 8 with the slightly longer roofing screw 8A.
Fig. 4 shows the entire apparatus fastened to the steel rib roofing 12 with the roof jack adapter 1 the standard roof jack 7 the support mechanism 6 the support plank 7A the slots in the standard roof jack 9 the slightly longer roofing screw 8A and the piece of steel flat bar 10.
FIELD OF THE INVENTION
A roof jack adapter which will allow a standard roof jack to be used on steel rib roofing without damaging the finish on the steel roofing.
BACKGROUND OF THE INVENTION
Roof jacks in various forms have existed for a long time. The primary use of the standard roof jack has been to allow the individual working on a roof with a steep pitch to have a stable platform to work from.
The roof jack adapter will allow the standard roof jack to be used with the adapter to be secured in place in a position above the rib of the steel rib roofing allowing work to be carried out without damaging the finish on the steel roofing particularly in situations where routine maintenance to items such as chimney's must be done.
SUMMARY OF THE INVENTION
The preferred embodiment of the roof jack adapter would be an 18 inch piece of steel flat bar with holes drilled in the outside edges allowing non abrasive elevators to be fastened to the long sides of the rectangular piece of steel flat bar in a position parallel with each other.
The non abrasive elevators would hold the steel flat bar in a position above the rib on steel rib roofing allowing a standard roof jack to be fastened to the roof jack adapter in a manner which would be secure, and cause no damage to the roofing material.
A support device in the form of a threaded hole with a like threaded screw or a protruding stud would be fixed to the steel flat bar allowing the standard roof jack to be held in position on the roof jack adapter thus allowing easy installation of the entire apparatus on the roof. The piece of steel flat bar would also have two holes directly above the support device. The two holes as well as the support device would be at the upper and in the center of the steel flat bar with the spacing of the holes and support device such that they directly line up with the slotted holes on a standard roof jack.
The roof jack adapter with the standard roof jack attached can be fastened to the roof by removing an existing roofing screw and then placing a new slightly longer roofing screw through the standard roof jack and the roof jack adapter in the same place the old screw was removed. A secondary screw may also be used to ensure the entire apparatus will not pivot and move on the roofing surface.
The non abrasive elevators can easily be changed in their thickness or position on the steel flat bar allowing the adapter to be used on a variety of different configurations of steel rib roofing. This roof jack adapter provides a fast easy cost effective way to deal with one of the major problems associated with working on finished steel rib roofing.
The accompanying drawings will give a better understanding of the exact use of the roof jack adapter.
