Publication number: 20230313562Abstract: A lock assembly includes a plug with a keyway, primary pins aligned with the keyway for controlling rotation of the plug, a sidebar for controlling rotation of the plug, secondary pins adjacent the keyway for controlling movement of the sidebar, and at least one supplemental sidebar control element for controlling movement of the sidebar. The lock assembly is operated by simultaneously manipulating the primary pins, the secondary pins, and the supplemental sidebar control element to place each in a respective position and/or orientation to permit rotation of the plug and to permit sufficient movement of the sidebar to permit rotation of the plug and then applying torque to the plug.Type: ApplicationFiled: April 10, 2023Publication date: October 5, 2023Applicant: ASSA ABLOY HIGH SECURITY GROUP INC.Inventors: Mark BENZIE, Douglas E. TRENT, Samuel D. WOOD, Peter H. FIELD, Walter DANNHARDT, Thomas DUCKWALL

Patent number: 11624206Abstract: A lock assembly includes a plug with a keyway, primary pins aligned with the keyway, a sidebar, secondary pins adjacent the keyway, and at least one supplemental sidebar control element for controlling movement of the sidebar. A key blank has a key blade with a primary top edge to receive primary bittings for controlling the primary pins, a rib to receive secondary bittings for controlling the secondary pins, and at least one shuttle pin. The shuttle pin engages a multi-level ridge within the keyway to move the shuttle pin from a retracted position to an extended position in which an end of the shuttle pin actuates the supplemental sidebar control element.Type: GrantFiled: October 2, 2020Date of Patent: April 11, 2023Assignee: ASSA ABLOY HIGH SECURITY GROUP INC.Inventors: Mark Benzie, Douglas E.

Patent number: 10253526Abstract: A lock cylinder assembly includes a housing, a first cylinder disposed within a first bore formed in the housing, and a second cylinder disposed within a second bore formed in the housing, in which at least one of the first and second cylinders is an electronic cylinder. The lock cylinder assembly further includes first and second cams, in which each of the first and second cams are configured to actuate a door lock mechanism. The first cam is directly connected to the second cylinder so as to be rotatable with the second cylinder. The second cylinder and the second cam are rotatable with respect to each other so that the second cam does not rotate with the second cylinder. The second cam is rotatably coupled to the first cylinder so that the second cam rotates when the first cylinder is rotated.Type: GrantFiled: May 3, 2017Date of Patent: April 9, 2019Assignee: Assa Abloy High Security Group Inc.Inventors: Douglas E. Trent, James Bench, Mark Benzie, Lance Schoell

Patent number: 7895865Abstract: The present application relates to lock assemblies that provide a secondary coupling point, utilizing an anti-rotation pin or extended tailpiece leg or other method, which rotationally couples the tailpiece to the cylinder plug, thereby preventing rotation of the tailpiece independently of the cylinder plug. Therefore, a tailpiece within a bolt cam or other actuator used to withdraw a bolt or unlock a lockset cannot be rotated after the tailpiece connector connecting the tailpiece to the cylinder plug has been forcibly removed, severed, or destroyed.Type: GrantFiled: August 14, 2008Date of Patent: March 1, 2011Assignee: Medeco Security Locks, Inc.Inventors: Glenn Hartman, Mark Benzie, Dan Boadwine, Clyde T. Roberson, Doug Trent, Peter H. Field

Patent number: 6945082Abstract: A key blank, key and master keying system for a twisting tumbler sidebar lock of the type where the sidebar is blocked or unblocked by a selectively positioned longitudinally extending slider, has a key blank with a slider contacting surface on a rib on the blank below the bitting area at one of a plurality of selected predetermined locations. A key with skew cut bittings can be cut on the blank and the blank can be configured with the slider contacting surface at different predetermined locations. The slider contact area on the rib of the key blank can be divided into two horizontal portions at different predetermined locations and the slider itself can have contact surfaces also positioned at different predetermined locations so that a number of different master keying variations are possible.Type: GrantFiled: October 1, 2002Date of Patent: September 20, 2005Assignee: Medeco Security Locks, Inc.Inventors: Peter H. Field, Andy E. Perkins, Anthony Hicks, Mark Benzie, Glenn Hartman, Clyde Roberson, Thomas Duckwall, Kevin Lee, W. Daniel Boadwine
