Abstract

A drill resistant lock cylinder (100) is useful for resisting attempts to defeat the cylinder (100) using locks or picks. The cylinder (100) includes a cylinder housing (105) having a central axis. Two pinion cylinders (115, 125) are positioned inside the cylinder housing (105) along the central axis. A
combination pin cylinder (120) is positioned along the central axis between the two pinion cylinders (115, 125), and the combination pin cylinder (120) and each pinion cylinder (115, 125) includes axial pinholes (220) there through. Pins (130) located inside the axial pinholes (220) in the combination pin cylinder (120) and the pinion cylinders (115, 125) establish two shear lines along axial ends of the pinion cylinders (115, 125).

Claims (8)

1. A drill resistant lock cylinder comprising:
a cylinder housing having a central axis;

two pinion cylinders positioned inside the cylinder housing along the central axis;

a combination pin cylinder positioned along the central axis between the two pinion cylinders, wherein the combination pin cylinder and each pinion cylinder includes axial pinholes there through; and pins located inside the axial pinholes in the combination pin cylinder and the pinion cylinders, whereby two shear lines are established along axial ends of the pinion cylinders.
2. The drill resistant lock cylinder of claim 1, wherein the pins are of variable lengths, enabling a key having pins of corresponding variable lengths to be inserted at an axial end of the housing, causing the pins to align along the two shear lines and place the cylinder in an unlocked configuration.
3. The drill resistant lock cylinder of claim 1, further comprising an anti-drill disc at one end of the cylinder housing.
4. The drill resistant lock cylinder of claim 1, wherein the pinion cylinders include opposing pinion teeth designed to engage a rack for sliding a bolt in and out of a locked position.
5. The drill resistant lock cylinder of claim 1, wherein the axial pinholes are positioned equidistant from each other at a constant radius from the central axis of the housing, thereby enabling the cylinder to be locked in a plurality of rotational positions.
6. The drill resistant lock cylinder of claim 1, further comprising a detachable key.
7. The drill resistant lock cylinder of claim 6, wherein the detachable key includes a plurality of key combination discs of varying thicknesses for changing a mechanical combination required to unlock the lock cylinder.
8. The drill resistant lock cylinder of claim 6, wherein the pins are connected to segments that are secured in a key receptacle.
