ABSTRACT:
The present invention relates to locking door latches. A door latch according to the invention may include a handle assembly that includes a generally cylindrical shank having an axis, an engagement member that includes a generally cylindrical bore configured to permit the shank to pass through the engagement member, a spindle operable by the shank, and a live bolt assembly coupled to the spindle so as to be actuated by the spindle. The handle is movable in a direction parallel to the axis between a first position and a second position. In the first position, the shank engages the engagement member so as to prohibit the shank from rotating about the axis. In the second position, the shank does not engage the engagement member so as to permit rotation of the shank about the axis.
