Drawer system slide assemblies and closure mechanisms

A self-closing drawer slide system includes first and second slide members and a self-closing mechanism which, in turn, includes a housing coupled to the first slide member, a carriage slidably coupled to the housing, and a spring coupled between the housing and the carriage. The carriage has an engagement area that selectively receives a cam/tab extending from the second slide member. As the drawer is pulled open, the carriage disengages from the cam/tab as it rotates and is locked in place. As the drawer returns, the carriage again engages the cam/tab, unlocks, and is pulled toward a drawer-closed position by the spring. The system may also include an intermediate member, with respective sets of three balls disposed between the intermediate and first and second slide members such that respective centers of the balls define corners of an obtuse triangle. The self-closing mechanism may also include a damper.
