Abstract
A compact, low-cost hinge assembly for mounting a door to a household appliance. A stay bar has first and second elongate edge surfaces extending between opposing first and second ends. The first end is pivotally connected to a door-mounting bracket on which an abutment is located. A torsion spring is mounted to a body-mounting bracket, and an arm of the spring resiliently engages the first edge surface to urge the second surface into engagement with the abutment, urging the door, in a closed position, toward the closed position. A detent recess in the second surface receives the abutment to hold the door partially open. A stop face projects from the first edge surface, and the spring arm contacts the stop face to hold the door horizontal, in a fully open position.
Claims11
A hinge assembly for mounting a door to the body of a household appliance, comprising:
- a door-mounting bracket for mounting to the door;
- a hinge pin for pivoting the door about an axis between a closed position, a first open position near the closed position, and a second open position;
- a body-mounting bracket for mounting to the body;
- an abutment on the body-mounting bracket;
- a stay bar having first and second elongate surfaces extending between opposing first and second ends of the stay bar, the first end being pivotally connected to the door-mounting bracket, at least one detent recess in the second surface proximate the first end, and a stop face projecting from the first surface proximate the second end;
- and
- a spring mounted to the body-mounting bracket, the spring having an arm slidingly and resiliently engaging the first surface to apply a torque to the stay bar to urge the second surface into engagement with the abutment, wherein
- the arm cooperates with the abutment to urge the door, in the closed position, toward the closed position
- the abutment is received in the at least one detent recess to hold the door in the first open position, and
- the arm contacts the stop face to support the door in the second open position.
