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 refrigerator including an inner door rotatably coupleable to a cabinet to open and close a storage compartment, the inner door having an opening, an outer door rotatably coupleable to the front of the inner door to open and close the opening of the inner door, a hook locking groove formed on the inner door, a manipulation handle provided to be rotatable with respect to a transverse shaft coupleable to the outer door and including a movable contact part, and a locking member provided to be rotatable with respect to a longitudinal shaft coupled to the outer door, wherein the locking member includes a hook lockable to and unlockable from the hook locking groove, and a passive contact part to selectively contact with the movable contact part.

A screen door cross bar is cooperable with a screen door assembly including a door frame and a latch assembly with a latch handle. The screen door cross bar includes a mounting bracket securable to the door frame on a side of the door frame opposite from the latch assembly, and a bar pivotally attached at one end to the mounting bracket. The bar is configured to engage the latch handle at an opposite end. The cross bar is designed to be fixed at a pivot point on the non-latch side of the screen door and receive the latch at the latch-side of the door to pivot and move vertically with the latch as it is actuated.

A deadbolt assembly for securing co-mounted doors together and activating at least one deadbolt may include at least a first retention component and a first actuator interface mounted to or defined by a first coupling assembly of a key-side assembly operatively mounted to one of the co-mounted doors, and at least a second retention component and a second actuator interface mounted to or defined by a second coupling assembly of a lever-side assembly operatively mounted to the other of the co-mounted doors, at least one of the key-side assembly and the lever-side assembly including a deadbolt assembly having a deadbolt configured to be responsive to actuation thereof to extend a deadbolt therefrom, wherein actuation of the deadbolt assembly also causes the first and second retention components to secure the first and second coupling assemblies to one another.

A home appliance is provided. The home appliance includes a main body having an accommodation space, a first door rotatably coupled to the main body to open and close the accommodation space and having an opening, a second door rotatably coupled to the first door to open and close the opening, and a locking device configured to fix or separate the first door to or from the main body or fix or separate the second door to or from the first door. The locking device includes a main ring unit, an operating lever configured to separate the second door from the first door by pressure, and a dual opening preventing member configured to maintain a fixed state of the second door with respect to the first door when the operating lever is pressed in a state in which the first door is open.

A double-door lock assembly includes a first lock and a second lock which are mounted to a first door and a second door, respectively. The first lock includes a first rotary member, a first magnetic member and a linkage member. The second lock includes a second rotary member having a driving portion and a second magnetic member. The first and second rotary members can be driven to rotate together to open or close the first and second doors simultaneously when the first and second magnetic members are attracted to each other and the driving portion on the second rotary member contacts against the linkage member on the first rotary 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.
