Abstract
A self-close drawer mechanism includes a housing, a slidable self-close latch selectively positionable within the housing, a rotatable cam element in the housing, a flexible link system extending around the cam element, and a spring applying stored force to the sliding self-close latch through the flexible link. Dual cam surfaces in the cam elements realize a decreasing pull force as the user opens the drawer and provides smoother opening and closing operations with an improved user experience.
