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.

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.

Publication number: 20210230901Abstract: A key or key blank includes a key blade having a first edge, a second edge, and first and second opposed sides. The first edge has one or more edge bittings to elevate and/or rotate one or more tumbler pins of a lock with a vertically-oriented keyway, and one of the opposed sides has one or more side bittings to elevate and/or rotate one or more tumbler pins of a lock with a horizontally-oriented keyway. Side warding surfaces on the key blank are shaped and positioned to minimize the interference of peaks between the skewed bitting cuts on the key. A lock has a keyway configured for the key having edge bittings to elevate and/or rotate one or more tumbler pins of a vertical lock and side bittings to elevate and/or rotate one or more tumbler pins of a horizontal lock.Type: ApplicationFiled: January 22, 2021Publication date: July 29, 2021Applicant: ASSA ABLOY HIGH SECURITY GROUP INC.Inventors: Thomas DUCKWALL, Peter H.

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: 9920551Abstract: An electromechanical cylinder lock includes an outer lock shell and a rotatable lock barrel located therein which is controlled by dual locking features. A side bar or fence selectively blocks and permits rotation of the barrel with respect to the shell in response to insertion of a key into a keyway in the barrel. A slider bar is movable between a blocking position in which the side bar is prevented from permitting rotation of the barrel, and an unblocking position in which the side bar permits rotation of the barrel. Alternately, a blocking mechanism is provided to block motion of tumbler pins in the cylinder lock. A shape memory alloy actuator, such as a wire made of nitinol, disposed in the barrel is activated by an electric current in response to determination by an electronic control device whether an attempt to open the lock is authorized. Thermal interlock protection from external heating of the lock is also provided.Type: GrantFiled: January 24, 2013Date of Patent: March 20, 2018Assignee: ASSA ABLOY HIGH SECURITY GROUP INC.Inventor: Peter Field

Patent number: 9771738Abstract: A cylinder lock with a rotating tumbler pin, a sidebar, and a slider has a keyway with a ward projection into the center of the bitting area of a key blade received by the keyway. The tip of each rotating tumbler pin seats on the bitting surfaces remaining to the sides of this center ward of the key, and the tumbler pins that are engaged by the bitting on the side of the key blade do not seat on more than half of the width of the blade. Half the pin width is removed from each tumbler pin near the tip thereof. The key has a bitted section at which one or more bittings are formed and a non-bitted section bitting that is devoid of bitting. The bittings extend at a constant depth to an edge of the key blade.Type: GrantFiled: January 26, 2015Date of Patent: September 26, 2017Assignee: ASSA ABLOY HIGH SECURITY GROUP INC.Inventors: Peter H. Field, Glenn Hartman

Patent number: 9482031Abstract: A cylinder lock includes a side bar assembly comprising a binding bar and a testing bar and code pins, each comprising a key projection, a code hole, and binding features. Partial rotation of the cylinder causes the binding bar to engage the binding features of the code pins to prevent radial movement of the pins. If the code holes of the code pins are aligned with code points of the testing bar, the testing bar is able to move inwardly with the binding bar and out of the slot so as to permit the cylinder to rotate within the bore. If one or more code holes is not aligned with a code point of the testing bar, the code point will contact the body of the code pin and thereby be prevented from moving radially inwardly out of a locking slot, thus blocking rotation of the cylinder.Type: GrantFiled: July 29, 2015Date of Patent: November 1, 2016Assignee: ASSA ABLOY HIGH SECURITY GROUP INC.Inventors: Peter H. Field, Torsten Quast
