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.

Abstract: A panel connector for use in connecting a plurality of panels such as to form a display. The connector is defined by a spring clip, of suitable length, forming an arcuate bead on the edge of the panel to be connected and adapted to be received in a complementary socket element. The clip includes inturned legs providing an improved support of the panel edge, maintaining the panel edge centered in the clip and against undesirable outward movement of the panel from the clip. The socket element may be arranged to permit selective angular disposition of the panel through a preselected wide angular range for facilitated arrangement of the panels as desired. The socket element may define a plurality of sockets for receiving a corresponding plurality of panel edges and opposite edges of the panels may be connected to different socket elements to permit a series arrangement of the panels and socket elements.
