Abstract
A door latch operating assembly is capable of rotating a door latch arm between a first locked position for locking a door in a closed position and a second unlocked position for unlocking the door. The latch operating assembly includes a lock platform and a handle having a gripper portion which is grasped by a person's hand for rotating the handle, and a shaft portion attached to the gripper portion and extending therefrom through an opening in the lock platform. A driver cam has a housing which receives the shaft portion of the handle, and at least one wing member extending laterally outwardly from one side of the housing. The wing member has an upwardly facing engaging surface for engaging a link which is linearly movable with respect to the lock platform. The link has a bottom edge portion with a downwardly facing engaging surface which bears against the upwardly facing engaging surface of the wing member of the driver cam, and a top edge portion with an upwardly facing engaging surface. A disk is rotatably mounted on the face plate of the lock platform about an axis of rotation and has a detent radially spaced from the axis of rotation which is engageable with the upwardly facing engaging surface of the top edge portion of the link. The link rotates the disk upon movement of the link. A shaft is mounted on the disk and rotatable about the axis of rotation, the shaft carrying the latch arm thereon whereby the latch arm is moved between its first and second positions.
