Samsung patents fridge door with a built-in stop to limit how far it opens
Samsung has filed a patent for a refrigerator design featuring a double-door system where the outer door swings open over the inner door. The hinge includes a specific stopper and limiter mechanism that physically blocks the outer door from rotating past a certain angle. This setup ensures the outer door does not swing too far back into the kitchen or hit the wall.
In the filing’s own words
A refrigerator may include: a main body including a storage compartment, and an inner and an outer case; an inner door that is rotatable to open and close the storage compartment, the inner door including an opening; an outer door in front of the inner door and that is rotatable to open and close the opening; a hinge to which the outer door is coupled, and including: a shaft that allows the outer door to rotate, and a rotation limiter on the shaft configured to limit an opening angle of the outer door relative to the inner door; and a stopper on the outer door and configured to: with the outer door rotated relative to the inner door, move along a circumference of the shaft, and with the stopper in contact with the rotation limiter, limit the opening angle of the outer door relative to the inner door.
What exactly they claim (claim 1)
1. A refrigerator comprising: a main body, in which a storage compartment is formed, the main body including an inner case and an outer case; an inner door that is rotatable relative to the main body to open and close the storage compartment, the inner door including an opening; an outer door in front of the inner door and that is rotatable relative to the inner door to open and close the opening; a hinge to which the outer door is coupled, the hinge including: a shaft that allows the outer door to rotate, and a rotation limiter on the shaft that is configured to limit an opening angle of the outer door relative to the inner door; and a stopper on the outer door and configured to: with the outer door rotated relative to the inner door, move along a circumference of the shaft, and with the stopper in contact with the rotation limiter, limit the opening angle of the outer door relative to the inner door.
