ABSTRACT:
A mechanism for providing a biasing force in the desired directions at appropriate degrees of refrigerator door opening. An cam mounted to the door has a lateral wall with three interconnected linear sections joined with predetermined included angles. An arm is pivotally mounted in an aligned slot in the refrigerator housing and is spring biased into engagement with the cam. The arm and cam are arranged so that the arm exerts a strong door closing bias on the first cam section when the door is closed, exerts a greater door closing bias on the second section when the door is partially open and exerts a slight door opening bias on the third section when the door is more fully open.
