ABSTRACT:
A window latch mechanism having first and second closure members for attachment to respective first and second double-hung windows. Hingeably attached to the first closure member is a tongue having a distal tooth. When the closure members are in an open configuration thereof, the tongue may be selectively rotated about a hinge to an easy open position or to a vertical ready-to-latch position. The first closure member also includes a vertically extending biasing wall adjacent to a base of the tongue. The second closure member includes a bar positioned to be overlapped by the tooth when in a closed and locked position thereof. The mechanism also includes at least one restraining boss positioned opposite the bar relative to the tongue for selectively allowing the tongue to be biased away from the bar and interferringly held by the boss away from the bar in a closed but unlatched position to allow the windows to be opened.
