Abstract
A door latch which provides leverage to the door in both the closing and opening operations of the latch's door handle. The door latch has a door axle attached to an edge of the door and a striker is attached to the cabinet. A latch pivoting component has a base bearing journaled to the door axle and a handle attached to the base bearing for manually rotating the base bearing about the door axle. A cam is attached to the base bearing and is engageable with the striker by rotation of the base bearing. The cam includes a closing cam segment and an opening cam segment. The opening cam segment engages and slides along the striker as the latch pivoting component is rotated in an opening direction of rotation. The closing cam segment engages and slides along the striker as the latch pivoting component is rotated in a closing direction of rotation.
