摘要： A longitudinal side bar is employed in connection with a standard type of cylinder lock having wafer tumblers with ears that extend through a opening in the rotatable cylinder into the cylinder housing. In order to open the lock, the tumbler ears must be retracted into the cylinder. The longitudinal side bar is held in a longitudinal groove in the rotatable cylinder. When the cylinder rotates, the side bar cams radially inward to engage the tumblers. When the lock is being comprised and torque is applied to the cylinder, the cylinder rotates a predetermined amount even though the tumbler ears are not retracted. The side bar will then ride in to engage the edges of the tumblers to prevent further retraction of the tumbler ears. In this fashion, compromise of the lock is defeated. A sheet metal curved leaf type spring is also employed to grip the tumblers and provide a constant spring force tending to prevent the tumblers from being aligned by a pick.
