  • Publication number: 20250092716
    Abstract: A key cam according to certain embodiments generally includes a shell, a lost motion driver, a plug, and a lock control lug. The shell extends along a longitudinal axis defining a proximal direction and an opposite distal direction. The lost motion driver is rotatably seated in a proximal end portion of the plug, and is operable to rotate the shell with lost rotational motion. The plug is rotatably seated in the shell and includes a proximal bowtie opening and a distal bowtie opening. The lock control lug is movably seated in the shell and projects into a lock control opening of the shell.

  • Publication number: 20250027343
    Abstract: 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.
