There is provided a closing device for a filler port. This closing device for the filler port comprises a fuel passage forming portion configured to include a first engagement element; a first open-close mechanism configured to include a first cover that is opened toward an upstream side; and a second open-close mechanism configured to open and close a second opening and include a second cover that is opened toward the upstream side. The first open-close mechanism further comprises a disengagement portion located on the upstream side of a second engagement element when the second engagement element is engaged with the first engagement element, and configured to disengage the second engagement element from the first engagement element when receiving a force in a closing direction from the second cover.

Disclosed is a refrigerator, more particularly a refrigerator including dual doors that are convenient to use. The refrigerator includes a main body having a storage space therein, a first door hinged to the main body for opening and closing the storage space, a door frame provided at the first door, a second door hinged to the first door, the second door having a side wall, at least a portion of which is inserted into the door frame, and a catching part provided in the side wall, and a locking device for selectively allowing the second door to be turned with respect to the first door, wherein the locking device includes a moving member, the displacement of which is changed depending on the open or closed state of the first door, and a catching member, the displacement of which is changed depending on the displacement of the moving member, whereby the protruding length of the catching member from the door frame is changed, the catching member being selectively caught in the catching part.

A refrigerator includes a cabinet that defines a storage space, a main door having an opening, and a sub-door configured to, based on rotating in the rotation directions of the main door relative to the main door, open and close the opening of the main door. The sub-door further includes an operation unit disposed at a lower side of the sub-door and configured to be operated by a user, a latch unit disposed vertically above the operation unit and configured to catch a portion of the main door, and a connection unit that connects between the operation unit and the latch unit. The connection unit includes a connection member that extends from an upper end in contact with the latch unit to a lower end in contact with the operation unit, and a connection member case defining a connection member accommodating portion that receives the connection member.

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.

An appliance door closure assembly is provided and comprises an inner door selectively coupled with an outer door. An anchor is in connection with the inner door and defines a retention space. A latch assembly is in connection with the outer door. The latch assembly includes a first cam having a first contact surface and pivotally coupled to a base. A second cam has a second contact surface engaged with the first contact surface of the first cam. The latch assembly is movable between a first position and a second position.

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.

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.
