Safety grain bin door latch system
A safety door latch system is presented for a grain bin having a door frame. An inner door is connected to the door frame that is configured to move between an open position and a closed position. An outer door is connected to the door frame and is configured to move between an open position and a closed position. A safety mechanism is connected to the door frame and is configured to move between an open position and a closed position. When the inner door frame is moved to a closed position, a portion of the inner door engages the safety mechanism thereby causing the safety mechanism to move to the closed position. When the safety mechanism is in the closed position, the outer door may be latched to the safety mechanism. When the safety mechanism is in the open position, the outer door cannot latch to the safety mechanism.
REFRIGERATOR
Disclosed herein is a refrigerator in which the structure of a door is improved. The refrigerator includes a main body having a storage compartment, a door rotatably coupled to the main body to open or close the storage compartment and having a door frame, a coupling member coupled to the door frame, and a door handle coupled with the coupling member in a sliding manner.

LATCHING ASSEMBLIES FOR DOOR-IN-DOOR REFRIGERATOR APPLIANCES
A latching assembly for a refrigerator appliance having inner and outer doors includes a catch and a latch. The latch is operable to engage the catch. As a result of such engagement, the inner and outer doors are latched together when the latch is engaged with the catch. The latching assembly also includes a trigger connected to the latch. The trigger is movable within a plane perpendicular to the vertical direction from a first position to a secondary position. The latch moves within the plane perpendicular to the vertical direction when the trigger moves to the secondary position. As a result, the latch is disengaged from the catch by moving the trigger within the plane perpendicular to the vertical direction to the secondary position.

DOOR ASSEMBLY FOR SELECTIVELY INTERLOCKING OPPOSING DOORS
A door assembly for selectively interlocking opposing doors each pivotably mounted at a hinge side thereof to a door frame so as to both open and close in the same direction includes a door handle assembly mounted to one door at a latch side thereof opposite the hinge side and carrying a first plurality of magnets, and another door handle assembly mounted to the other door at a latch side thereof opposite the hinge side and carrying a second plurality of magnets. The door handle assemblies are arranged relative to each other with the first and second pluralities of magnets aligned such each aligned pair of the first and second pluralities of magnets have opposite magnetic polarities, and the aligned first and second pluralities of magnets magnetically couple to each other as the door handle assemblies are brought into contact with each other.

Door latch assembly
A door latch assembly includes a housing, an inside and outside handle operably coupled with the housing, and a latch plunger. A latch cam is operably coupled with the inside and outside handles, and the latch cam further includes a crank arm slidably disposed against an inclined surface of a plunger leg operably coupled to the latch plunger. A biasing member urges the latch plunger to an extended position, wherein rotation of the inside or outside door latch handle in a first direction rotates the crank arm of the latch cam and displaces the plunger leg of the latch plunger and the latch plunger to a retracted position against the urging of the biasing member.

Refrigerator
A refrigerator includes an opening unit such that, when a second door rotates to open a second storing chamber, the second door is separated from a first door. The opening unit includes: a latch hook to be selectively inserted into a latch slot on the front surface of the first door; a pressing portion provided on a door handle of the second door, the pressing portion comprising a guide protrusion having a sloping surface; and a link portion having a contact portion on one end to contact the sloping surface and move upward/downward along the sloping surface, the other end of the link portion contacting the latch hook. When the pressing portion is pressed, the contact portion moves upward along the sloping surface, and the other end of the link portion pushes the latch hook upward with the contact portion to separate the latch hook from the latch slot.
