发明名称 Releasable holding means for window or screen
摘要 Means for releasably holding a window or screen in a door frame. The door frame has a continuous flange around an opening to support one side of a window or screen and a plurality of recesses adjacent the opening. A slidable tab within each recess has an elongated slot therethrough and at least two runners on the underside upon which to slide the tab to and from an extended position within the recess. A threaded means passes through the elongated slot in the tab to a threaded hole in the base of the recess to releasably hold the tab in a selected fixed position. The tabs in extended position securely but releasably hold the window or screen against the flange on the frame.
