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 according to an embodiment of the present invention comprises an opening unit configured such that, when a second door rotates in order to open a second storing chamber, the second door is separated from a first door. The opening unit comprises: a latch hook provided on the second door so as to be selectively inserted into a latch slot formed on the front surface of the first door; a pressing portion provided on a door handle provided on the front surface of the second door, the pressing portion comprising a guide protrusion having a sloping surface formed on one side thereof; and a link portion having a contact portion formed on one end thereof so as to contact the sloping surface and to 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 together with the contact portion such that the latch hook is separated from the latch slot.

The present invention is a gate latching system for use in securing a pair of cooperating stock gates together. A preferred embodiment of the invention employs a pair of latching devices for securing a pair of overlapping stock gates together in a closed position. An alternate embodiment of the invention is designed with an extended arm for securing a pair of stock gates closed when the stock gates do not overlap. Both pairs of latching devices are designed so that one of the latching devices is bolted to one gate and the other latching device is bolted to the other gate. Each latching device has a u-shaped receiver for receiving a horizontal member of the opposite gate. The horizontal members enter the u-shaped receivers by lifting one of the gates as the gates are being closed and are secure therein by a lid that closes over one receiver.
