SYSTEM AND METHOD FOR ADJUSTING THE SPRING TORQUE OF A LOCK CHASSIS |
摘要 |
A latch assembly configured to attach to a door includes one of a knob and a lever. The latch assembly further includes a latch extending from the door. A spindle is rotatable from a first position to a second position to move the latch from an extended position to a retracted position. A first biasing member is selectively operable to bias the spindle toward the first position. A second biasing member is selectively operable to bias the spindle toward the first position. An actuator is movable between a knob position in which only one of the first biasing member and the second biasing member biases the spindle toward the first position and a lever position in which both the first biasing member and the second biasing member cooperate to bias the spindle toward the first position.
