Abstract
Abstract There is disclosed a removable vent window for a roof of an automobile which is particularly adapted for retrofit installation. The vent window is mounted in an opening extending across a major width of a car roof, preferably slightly rearwardly of the forward edge of the roof. The opening is framed with members of preformed or stretch formed extruded aluminum which are stretch formed into a generally rectangular frame to provide support for the hinges and latches that secure the vent window. The vent window is removably mounted in the opening by hinge members along the forward edge of the opening. The rear edge of the opening and window bear detachable latching mechanisms whereby the window can be pivoted between a closed, sealing position and an open, forwardly inclined, venting position. The latch mechanisms can be detached from the window, freeing the rear edge of the window and permitting it to be pivoted to an elevated position and disengaged from its hinges for complete removal of the window. The window is installed in existing roof panels by cutting the panel to the approximate dimensions of the desired opening, placing the preformed frame members into the opening and applying a bonding adhesive between the frame members and the panel surrounding the opening. The vent window is shaped with a surface contour that approximates the contour of the roof and the panel is mounted in the frame members and latched into its closed position so that the frame members and surrounding roof are clamped into the desired roof contour by the rigid window panel. The assembly is retained in this clamped configuration until the bonding adhesive has cured sufficiently that the frame members support the surrounding roof panel.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
234 words
In an automobile body having a fixed, rigid roof over the passenger compartment, the improvement comprising: an opening extending across a major width of said roof and positioned slightly rearwardly of the forward edge of said roof; frame means carried by said roof about the periphery of said opening; a vent closure panel having substantially the same shape and dimensions as said opening; a frame member having an upright main channel with a cross section having a web and parallel sides coextensive with the edge of said opening; an inwardly dependent channel having an arcuate cross section carried on the upper edge of the inboard side of the main channel of said frame member; a first pair of side-by-side grooves extending transversely across said dependent channel on one side of said frame member to provide an arcuate tongue there between; and a hinge plate mounted to said panel and bearing a slot along one edge thereof receiving said arcuate tongue to permit pivotal movement of said closure panel between a closed position over said opening and a forwardly inclined, open, vent position; closure panel seal means carried by said frame; and latch means secured at the rear edge of said closure panel and carried on the rear edge of said frame for locking said closure panel in said closed position against said seal means and for supporting said closure panel in said vent position.
Claim 2
Dependent Claim
