Abstract: A lock assembly includes a casing, two pivotable members pivotally mounted in the casing and meshed with each other, two linking rods, and two hook device each including a hook member and a rocker arm that is pivotally mounted in the casing. Each hook member has a first end pivotally connected to an associated rocker arm and a hooked second end that is passable through an associated one of two openings of the casing. When either pivotable member is pivoted, each rocker arm and each hook member are actuated such that the hooked second end of each hook member is moved between a retracted position in the casing and a locking position out of the casing. Damage to the hooked second ends of the hook members during closing of a door is prevented.

Abstract: A lock assembly includes a casing, a pivotable member pivotally mounted in the casing, two linking rods each having a first end pivotally connected to the pivotable member and a second end, and two hook devices each including a first hook member and a second hook member. Each second hook member is pivotally mounted in the casing. The second end of each linking rod is pivotally connected to an associated second hook member. Each first hook member includes a first end pivotally connected to the second hook member. Each hook member further includes a hooked second end that is passable through an associated opening of the casing. When the pivotable member is pivoted, each first hook member is pivoted such that the hooked second end of each first hook member is moved between a retracted position in the casing and an extended position out of the casing.
