ABSTRACT:
A door latch coupling arrangement includes a detent release member connected to an inside operator by a freewheeling connection. An intermittent member is movable between coupled and uncoupled positions with respect to the detent release member and pivotally connected to the inside operator to establish an operative connection between the detent release member and inside operator when in coupled position. A manual control member shifts the intermittent member between its coupled and uncoupled positions.
