Abstract:
1. An adjustable ventilator jack for ventilating a cover, said adjustable ventilator jack comprising: a dome comprising a dome portion and a depending shaft portion wherein said dome portion defines one of (a) a generally circular umbrella shape, and (b) a polygonal umbrella shape, wherein an axial center of said dome portion is an upper most portion and wherein an outer surface curves in a downward direction extending away from said axial center a predefined distance thereby defining a dome-outer-perimeter; wherein said shaft portion extends downwardly from said axial center of said dome portion and wherein said axial center of said dome portion and said shaft portion define a shaft opening suitably sized to receive a support structure form a bottom of the dome; two ventilator plates, wherein each ventilator plate comprises two opposed surfaces defining a plate hole there through in the approximate center, said plate hole defining a shaft receiver suitably sized to receive said shaft portion; wherein each ventilator plate further defines a vent section disposed at least partially around said shaft receiver, said vent section defining at least one air vent, and wherein said opposed surfaces extend from said vent section to a predefined point thereby defining an plate-outer-perimeter; a jack support that is one of (a) integral to said dome and (b) mechanically associated with said dome, wherein said jack support is attached on said outer surface of said dome and defines a jack-support-hole there through so that said jack-support-hole is in substantial alignment with said shaft opening to allow the support structure passed there through; wherein said jack support further defines a jack support interface suitably configured to releaseably receive a jack for releasably engaging with the support structure, configured to movably associate with said support structure so that said dome moves along said support structure when said jack is activated; and a fastening device configured to mechanically associate the ventilator plates and dome so that they clamp together.
