Abstract

A latching system includes a handle, a latch, a release rod, an arm portion, and a finger portion. The handle is attached to the door assembly and includes an escutcheon and a grip portion movable relative to the escutcheon between a first position, a second position, and a third position. The latch is attached to the door assembly and the release rod extends from the latch. The arm portion rotates relative to the escutcheon in response to moving the grip portion. The finger portion pivotally extends from the arm portion to an engagement member that is disengaged from the release rod when the pull grip is in the first position, engages the release rod when the pull grip is in the second position, and moves the release rod away from the handle and toward the latch to operate the latch when the pull grip is in the third position.
