Abstract
An axial pin tumbler lock for housing in an outer shell. The lock includes a shell and a rotatable driver sleeve telescoped into the shell. The driver sleeve has a bird-cage design including a front large inner diameter portion and a rear small-diameter inner portion and circumferentially arranged throughbores in communication with the inner diameters. A stationary tumbler sleeve is also telescoped in the shell, and in a facing relationship with the driver sleeve. The tumbler sleeve slot includes throughbores in communication with an inner diameter. A spindle extends through the sleeves and is rotatably mounted in the driver sleeve. The spindle includes a body portion and a neck portion with a curved transition zone between the two. Driver and tumbler pins mounted in the throughbores normally prevent rotation of the spindle and driver sleeve with respect to the tumbler sleeve.
