A latch has a displaceable latching element in a housing for engagement with a separate striker arm to be latched behind an engagement shoulder of the latching element. The housing mounts a cylinder lock to receive a key from the front. A rotor is mounted on the rear of cylinder lock and rotation of the key rotation the rotor to drive a locking element to engage and lock the latching element. The rotor may also be axial displaceable against spring biasing responsive to a rear unit pushing element whereby unlocking from a rear cylinder lock may rotate the rotor to unlock and pushing causes the latching element to be displaced against its biasing to release the striker arm. Embodiments include a gravity biased and manually opened latch and a spring biased self-locking embodiment.

A door-in-door refrigerator includes a door having an inner door and an outer door. When the inner and outer doors are in open positions, food items stored in a main refrigerated compartment are accessible. When the inner and outer doors are in closed positions, the door seals the refrigerated compartment, and food items stored in the main refrigerated compartment are not accessible. When the inner door is in a closed position and the outer door is in an open position, food items stored in a storage structure coupled to the door are accessible. A latch includes a trigger that moves in a direction substantially parallel to a handle. Movement of the trigger shifts the latch between a latched position, in which pulling on the handle causes the inner and outer doors to open, and an unlatched position, in which pulling on the handle causes the outer door to open while the inner door remains closed.

A thermal printer includes a housing, a head cover, and a locking mechanism, wherein the locking mechanism includes a lever member and a lock member which are configured so that i) as an operation part is pressed down, the lock member rotates in a direction to move a claw away from the lock pin, and a lock is released by the claw being disengaged from the lock pin and ii) as the operation part of the lever member is pulled up, a portion of the lever member presses the lock member, whereby the lock member rotates in a direction to move the claw away from the lock pin, and the lock is released by the claw being disengaged from the lock pin.

A lock apparatus includes: a housing; an opening and closing door that is rotatable about a support shaft of the housing; an engaging member that is movable and provided on one of the housing and the door; an engaged member provided on the other of the housing and the door; an operation member that is movable and provided on the door; and a lock mechanism configured to restrict a movement of the engaging member. When the door is closed, the engaging member is engaged with the engaged member into an engaged state. In the engaged state, when the engaging member is moved in conjunction with a movement of the operation member, the engaged state is released to allow the door to be opened. In the engaged state, when the lock mechanism restricts the movement of the engaging member, the movement of the operation member is restricted.

A latch assembly which provides a locking latch that pivots with movement of the handle and also pivots independently of movement of the handle in order to allow closure of the drawer or door without requiring that the handle be actuated to an open position for closure.
