A home appliance includes a main body having a storage compartment, a first door hingedly coupled to the main body that opens and closes the storage compartment, and a second door that rotates relative to the first door. The second door includes a latch receptor. The first door includes a locking device with a magnetic component and a latch member. In a state in which the first door closes the storage compartment of the main body, separating the magnetic component from the main body by a first distance, the locking device disengages the latch member from the latch receptor of the second door. In a state in which the first door opens the storage compartment of the main body, separating the magnetic component from the main body by greater than the first distance, the locking device engages the latch member into the latch receptor of the second door.

An integral door guide assembly is removably coupled in an opening of a door of a refrigerator and has an adjustable height. The refrigerator includes a first door rotatably connected to a front surface of a main body, and having an opening in which a plurality of door guide assemblies can be arranged, and a second door rotatably connected to a front surface of the first door. The door guide assembly includes a door guide, a guide removably fixed on both side walls of the opening, a moving unit removably coupled with both side walls of the door guide, guided by the guide to move in an up-down direction, a stopper coupled with the guide, and caught by or released from the catching projections to adjust a position of the moving unit and a latch configured to fix the stopper released from the catching projections.

A magnetic latching system is provided for removably latching a panel to an aircraft surface portion. The latching system includes a removable axis panel engageable to a latching land. The panel and land define opposing magnetically attractive surface portions, with a body of magnetic material disposed there between. An inflatable seal is also disposed intermediate the panel and the land. Upon inflation, the inflatable seal is operative to urge the panel away from the land far enough to reconnect magnetic engagement between the panel and the land, sufficient to permit disengagement of the panel from the land.
