Abstract
A pair of free linkages are disposed in a door latch housing between the housing, the latch bolt, and the latch bolt actuating buttons. Preferably, each linkage comprises a toggle hinge having first and second sides joined by a pivotable connection in a one piece polypropylene construction. The sides of the hinge taper approaching the pivotable connection so the pivotable connection is substantially thinner than the first and second sides. The taper of the first and second sides differs in alternating fashion across the pivotable connection to form a bearing surface alternately on one side of the pivotable connection and the other. Responsive to the movement of a privacy button to its latched position, movement of one of the actuating buttons is prevented without preventing movement of the other actuating button. Responsive to movement of the other actuating button, the privacy button returns to its unlatched position.
