Abstract
A segmented lock pin is presented. The segmented lock pin includes a first right cylinder, a second right cylinder, and a coupling member. The first right cylinder is movably joined to the second right cylinder by the coupling member. The first right cylinder is axially, laterally, and rotationally movable with respect to the second right cylinder. When implemented as a driver pin, the segmented lock pin provides no counterrotation feedback during a picking attempt of a lock in which the segmented driver pin is installed once the first right cylinder of the segmented driver pin is in a hull of the lock, the second right cylinder of the segmented driver pin is in a plug of the lock, and an edge of the second right cylinder engages the hull of the lock.
Claims19
A lock comprising:
- a hull;
- a cylindrical plug disposed within the hull, wherein the plug defines a keyway and a plurality of plug bores that communicate with the keyway through the plug, wherein the plurality of plug bores, in a locked position of the lock, communicate with a corresponding plurality of hull bores formed in the hull;
- a plurality of spring-loaded pin stacks comprising a plurality of key pins and a plurality of driver pins, each pin stack comprising a key pin and a driver pin, wherein the plurality of spring-loaded pin stacks are movable, by a key inserted into the keyway, to position interfaces between key pins and driver pins to a shear line between the plug and the hull to allow rotation of the plug about its longitudinal axis relative to the hull to unlock the lock;
- and
- a segmented driver pin of the plurality of driver pins, wherein the segmented driver pin comprises a first right cylinder, a second right cylinder, and a coupling member that is movably joined to the first right cylinder and movably joined to the second right cylinder, wherein the first right cylinder is axially, laterally, and rotationally movable with respect to the second right cylinder, and wherein the segmented driver pin provides no counterrotation feedback during a lock picking attempt once the first right cylinder is in the hull, the second right cylinder is in the plug, and an edge of the second right cylinder engages the hull.
A lock repinning kit comprising a plurality of pins for repinning a lock, the lock repinning kit comprising:
- a plurality of segmented pins, each segmented pin comprising a first right cylinder, a second right cylinder, and a coupling member that is movably joined to the first right cylinder and movably joined to the second right cylinder, wherein each first right cylinder is axially, laterally, and rotationally movable with respect to the respective second right cylinder.
A segmented lock driver pin comprising:
- a first right cylinder;
- a second right cylinder;
- and
- a coupling member,
- wherein the first right cylinder is movably joined to the second right cylinder by the coupling member, wherein the first right cylinder is axially, laterally, and rotationally movable with respect to the second right cylinder, and wherein the segmented lock driver pin provides no counterrotation feedback during a picking attempt of a lock in which the segmented driver pin is installed once the first right cylinder of the segmented driver pin is in a hull of the lock, the second right cylinder of the segmented driver pin is in a plug of the lock, and an edge of the second right cylinder engages the hull of the lock.
