Patent number: 12195999Abstract: An exemplary ring lock generally includes a housing, a shackle, a lock cylinder, and a first frangible component. The shackle is movable relative to the housing between an open position and a closed position. The lock cylinder is operable to maintain the shackle in the closed position, and is selectively operable to permit movement of the shackle from the closed position to the open position. The first frangible component is configured to break in response to application of a first threshold torque to the lock cylinder. With the first frangible component broken, the lock cylinder is prevented from permitting movement of the shackle from the closed position to the open position.Type: GrantFiled: September 23, 2022Date of Patent: January 14, 2025Assignee: Schlage Lock Company LLCInventors: Marco Stunnebrink, Manjunatha Ramakrishna, Ramamohan Bhaskar Shettigar, Arjun S. Kunnath, Ilias Baiazitov, Jan Gerbrand Hutten, Martin van Ede

Publication number: 20240384563Abstract: A lock apparatus generally includes a connecting portion, a housing, a primary lock, and a secondary lock. The connecting portion is engageable to the housing with a bolt assembly, and the primary lock locks the bolt assembly in the engaged position. The secondary lock arrests the bolt assembly in the engaged and locked condition in response to an attack that displaces the primary lock from a nominal configuration.Type: ApplicationFiled: May 15, 2023Publication date: November 21, 2024Inventors: Manjunatha Ramakrishna, Arjun S. Kunnath, Adithya Gangadhar Shetty, Ramamohan Bhaskar Shettigar

Publication number: 20240360696Abstract: An exemplary lock apparatus generally includes a shackle, a crossbar, a lock device, a first bolt, and a trigger. The lock device has a locked state in which the lock device retains a spindle in a spindle locking position, and an unlocked state in which the lock device does not prevent movement of the spindle to a spindle unlocking position. The first bolt is engaged with the spindle such that movement of the spindle between the spindle locking position and the spindle unlocking position drives the first bolt between a first locking position and a first unlocking position. The trigger is movably mounted in the crossbar for movement between an engagement position, in which the trigger maintains the spindle in the spindle unlocking position, and a disengagement position, in which the spindle is operable to move to the spindle locking position.Type: ApplicationFiled: July 9, 2024Publication date: October 31, 2024Inventors: Robert Townsend, Arjun S. Kunnath, Ramamohan Bhaskar Shettigar, Manjunatha Ramakrishna

Patent number: 11761244Abstract: An adjustable latch configured to accommodate different backset lengths. The adjustable latch includes inner and outer housings, at least a portion of the inner housing being structured for axial and rotational displacement within the outer housing as an engagement projection of the inner housing is displaced about an adjustment slot of the outer housing. The apparatus may include a bolt assembly having a bolt rod and a latch bar, the bolt rod having projections that are structured to be adjacent to the latch bar when the bolt rod is at a first rotational position and at first or second axial positions. When the bolt rod is at a second rotational position, the axial positions of the bolt rod and the inner housing relative to at least the latch bar and outer housing, respectively, may be adjusted to adjust the backset setting of the latch.Type: GrantFiled: November 2, 2021Date of Patent: September 19, 2023Assignee: Schlage Lock Company LLCInventor: Manjunatha Ramakrishna
