Abstract
A latch assembly includes coplanar pairs of magnets that engage each other when the latch assembly is in a closed position in order to secure the latch assembly in the closed position. A related appliance with features for selectively securing a door of the appliance in a closed position is also provided.
Claims16
A latch assembly, comprising:
- a housing;
- a holder pivotally mounted within the housing such that the holder is pivotable on a pivot axis relative to the housing, the holder defining a slot;
- a stator having a first end portion and a second end portion, the stator being mounted to the holder;
- a first magnet positioned at the first end portion of the stator, the first magnet having an outer surface;
- a second magnet positioned at the second end portion of the stator, the second magnet having an outer surface, the outer surface of the second magnet positioned coplanar with the outer surface of the first magnet;
- a carrier having a projection;
- a mover mounted to the carrier and having a first end portion and a second end portion;
- a third magnet positioned at the first end portion of the mover, the third magnet having an outer surface, the outer surface of the third magnet positioned adjacent the outer surface of the first magnet when the latch assembly is in a closed position;
- and
- a fourth magnet positioned at the second end portion of the mover, the fourth magnet having an outer surface, the outer surface of the fourth magnet positioned adjacent the outer surface of the second magnet when the latch assembly is in the closed position, the outer surface of the fourth magnet positioned coplanar with the outer surface of the third magnet,
- wherein the holder includes two distal end portions spaced apart from each other by a first length along the pivot axis, wherein the housing includes opposing side walls that are spaced apart from each other by a second length along the pivot axis, wherein the second length is greater than the first length, and wherein the holder linearly slides along the pivot axis between the opposing side walls of the housing in order to adjust to a lateral location of the carrier,
- wherein the slot of the holder is positioned on the holder between the first magnet and the second magnet, the projection of the carrier received within the slot of the holder when the latch assembly is in the closed position.

An appliance, comprising:
- a cabinet;
- a door pivotally mounted to the cabinet;
- and
- a latch assembly configured for selectively securing the door in a closed configuration, the latch assembly comprising
- a housing fixed relative to the cabinet;
- a holder pivotally mounted within the housing such that the holder is pivotable on a pivot axis relative to the housing;
- a stator having a first end portion and a second end portion, the stator being mounted to the holder;
- a first magnet positioned at the first end portion of the stator, the first magnet having an outer surface;
- a second magnet positioned at the second end portion of the stator, the second magnet having an outer surface, the outer surface of the second magnet positioned parallel to the outer surface of the first magnet;
- a mover having a first end portion and a second end portion, the mover positioned on the door such that the mover is fixed relative to the door;
- a third magnet positioned at the first end portion of the mover, the third magnet having an outer surface, the outer surface of the third magnet positioned at the outer surface of the first magnet when the door is in the closed configuration;
- and
- a fourth magnet positioned at the second end portion of the mover, the fourth magnet having an outer surface, the outer surface of the fourth magnet positioned at the outer surface of the second magnet when the door is in the closed configuration, the outer surface of the fourth magnet positioned parallel to the outer surface of the third magnet,
- wherein the holder includes two distal end portions spaced apart from each other by a first length along the pivot axis, wherein the housing includes opposing side walls that are spaced apart from each other by a second length along the pivot axis, wherein the second length is greater than the first length, and wherein the holder linearly slides along the pivot axis between opposing side walls of the housing in order to adjust to a lateral location of the door.
