Patent number: 11965356Abstract: In one form, a cylindrical lockset includes a chassis including a pair of hubs, a pair of drive tubes, a retractor, and a lock control assembly. The lock control assembly has a locked state and an unlocked state. The lock control assembly also has a plurality of movable elements, each having a locking position and an unlocking position. One of the hubs includes a guide channel, and a slider is movably seated in the guide channel. One of the movable elements is associated with the slider, and is configured to move the slider between a lock-indicating position and an unlock-indicating position.Type: GrantFiled: April 14, 2022Date of Patent: April 23, 2024Assignee: Schlage Lock Company LLCInventors: Smitha Basavaraju, Kenton H. Barker, Harikrishnan Mannattil, Subbiah Gopalakrishnan, David J. Hurlbert, Ajeya S. Rao, Achyuta Dhanvantri

Publication number: 20240102311Abstract: A handleset includes a housing, a spindle sleeve, a handle, a coupler, and a spindle. The spindle sleeve includes an aperture, and is rotatably mounted to the housing. The handle is mounted to the spindle sleeve and includes a recess aligned with the aperture. The coupler is movably mounted in the aperture for movement between a decoupling position and a coupling position. The coupler in the coupling position is disengaged from the recess and does not prevent removal of the handle from the spindle sleeve. The coupler in the coupling position extends into the recess and prevents removal of the handle from the spindle sleeve. The spindle is movably received in the spindle sleeve and selectively retains the coupler in the coupling position.Type: ApplicationFiled: December 5, 2023Publication date: March 28, 2024Inventors: Drake Lunday, Adam M. Litwinski, David J. Hurlbert, Zachary Wiggins, Marshall Owens

Patent number: 11920379Abstract: An exemplary product line system includes a common platform and a plurality of component families, each of which includes a plurality of interchangeable component species configured for use with the common platform. The common platform includes an inside drive assembly and a chassis assembly including a chassis and an outside drive assembly. A lockset assembled from the system includes the common platform and a plurality of modular components. Each of the modular components corresponds to a respective one of the component families, and is provided as a selected species of the corresponding component family. The lockset has a function defined by the set of component species installed to the lockset. The function of the lockset can be changed by altering the set of component species installed to the lockset without disassembling the chassis assembly.Type: GrantFiled: August 3, 2021Date of Patent: March 5, 2024Assignee: Schlage Lock Company LLCInventors: Kenton H. Barker, Subbiah Gopalakrishnan, David J. Hurlbert, Kasey Wachtendorf, Snehil Solanki, Dilip Bangaru, Austin M. Roup, Rakesh Murali

Patent number: 11905735Abstract: A lockset including a chassis having a locked state and an unlocked state, a latchbolt connected with the chassis, a handle mounted to the chassis, and a lock cylinder connected with the chassis. The handle is operable to retract the latchbolt when the chassis is unlocked, and is inoperable to retract the latchbolt when the chassis is locked. The lock cylinder includes a shell and a plug selectively rotatable relative to the shell. The chassis is configured to transition from the locked state to the unlocked state in response to rotation of the plug in a first rotational direction from a home position to a first rotated position. The chassis is configured to return from the unlocked state to the locked state in response to rotation of the plug in a second rotational direction from the first rotated position to the home position.Type: GrantFiled: October 19, 2020Date of Patent: February 20, 2024Assignee: Schlage Lock Company LLCInventors: Snehil Solanki, Kenton H. Barker, James D. Ohl, Greg Hebner, David J. Hurlbert

Publication number: 20230026356Abstract: The present disclosure is directed to a lock assembly that can be converted between a clutching and non-clutching orientation by rotating an outer housing 180 degrees relative to an outside drive assembly. The outer housing includes a notch and an elongate arcuate slot formed in the inner surface of the outer housing adjacent a through aperture and across from one another. A lock control lug is moveably coupled with the outside drive assembly and is selectively engageable with the notch or the arcuate slot of the outer housing. An outer lever is placed in a non-clutching configuration when the lock control lug is engaged with the notch and in a clutching configuration when the lock control lug is engaged with the arcuate slot.Type: ApplicationFiled: July 5, 2022Publication date: January 26, 2023Inventors: Kenton H.
