Abstract
A multi-joint link hinge includes a hinge bracket, a plurality of side portions, a link module, and a door bracket coupled to the link module. The hinge bracket includes a base portion that defines a plurality of screw coupling holes at a vertical surface of the base portion, and a plurality of side portions that extend from the base portion in a horizontal direction and are spaced apart from each other in a vertical direction. The link module includes a plurality of links that are coupled to the plurality of side portions along an axis that extends in the vertical direction, where the plurality of links is disposed between the plurality of side portions.
Claims20
A multi-joint link hinge comprising:
- a hinge bracket comprising:
- a base portion that defines a plurality of screw coupling holes at a vertical surface of the base portion, and

- a link module comprising a plurality of links that are coupled to the plurality of side portions along an axis that extends in the vertical direction, the plurality of links being disposed between the plurality of side portions;
- and
- a door bracket coupled to the link module.
A multi-joint link hinge comprising:
- a hinge bracket comprising:
- a base portion that defines a plurality of screw coupling holes at a vertical surface of the base portion, and
- a support portion that protrudes from the vertical surface and extends in a horizontal direction;
- a link module comprising a plurality of links, each link being coupled to a top surface of the support portion or a bottom surface of the support portion;
- and
- a door bracket coupled to the plurality of links.
A refrigerator comprising:
- a cabinet that defines a storage space;
- a door configured to rotate relative to the cabinet and to open and close at least a portion of the storage space;
