Abstract: A lock assembly for cabinet doors comprising a mounting plate attachable to the door panel and provided with a depression in its front face to receive a handle. The handle is connected to an operating shaft for a lock adjusting member in a spring loaded manner to cause the handle to be ejected from the depression pivoting about an axis perpendicular to the axis of rotation of the adjusting member. The hand lever is retained in and released from the depression by means of the lock assembly. The lock is installed in the mounting plate separate from the depression with the handle therein, and penetrates the door panel through an opening. The lock controls a slide adjustably disposed in the mounting plate by means of a detent element engaged in the depression, the detent element retaining the handle in the depression when the lock is in the locking position and releasing the handle which is ejected from the depression when the lock is in the unlocked position.
