<p>A latch drive set includes a rotatable drive member (40) having means (50, 53) for engaging the drive member with spindle, for rotating the spindle about an axis to operate a latch unit, and a mounting plate (20) for rotatably supporting the drive member with respect to the latch unit so that the drive member (40) at least partly overlies the mounting plate (20) in the direction of the axis. Means (81, 83) is provided on the drive member for coupling the drive member to a handle unit in an annular zone extending about the axis so that the handle unit at least partly overlies the drive member in the direction of the axis when so coupled. In situ, rotation of the handle unit is effective to rotate the spindle via rotation of the drive member. Also disclosed are a privacy adaptor set and a lever handle arrangement.</p> |
