A lockset for a door comprising a latchbolt assembly including a bolt movable between a fully extended deadbolt locked position, and a retracted position. A spindle extends through the latch assembly in a direction transverse of the direction of movement of the bolt. Rotation of the spindle results in the bolt moving between its positions. The lockset further includes an operating assembly comprising a hand operator having a lock therein, a first plate mounted for linear movement in a direction transverse of the axis of the spindle, an actuating member connected to the hand operator for moving the first plate, a second plate having linear movement transverse to the axis of the spindle and adapted to be moved by the first plate, and rotatable drive member attached to the spindle and adapted to be rotated by the second plate. The second plate is movable between bolt retracted, and fully extended positions. A detent member engages the second plate when the locking member is unlocked for preventing the second plate from moving between its bolt unlocked and bolt fully extended positions. |
