Abstract
A device is provided for use in actuating a locking lug in a cylindrical lockset. The device includes a mechanism for moving the locking device between door handle locking and unlocking positions. The moving mechanism includes a plunger having an axis, a locking-assist spring coupled to the plunger and the locking lug, and a mechanism for reciprocating the plunger along its axis in opposite directions. To lock the cylindrical lockset, the reciprocating mechanism moves the plunger along its axis in a locking direction against the locking-assist spring so that the locking-assist spring is moved toward the locking lug to urge the locking lug to its door handle-locking position. To unlock the cylindrical lockset, the reciprocating mechanism moves the plunger along its axis in an opposite, unlocking direction away from the locking lug so that the locking lug is allowed to move to its door handle-unlocking position.
