  • Patent number: 11851911
    Abstract: An exemplary pushbutton mechanism is configured for use with a lockset including a spindle and a plunger extending into the spindle, and generally includes a first component, a second component, and a cam interface. The first component is configured for rotational coupling with the plunger and for axial coupling with the spindle, and is rotatable between a locking orientation and an unlocking orientation. The second component is configured for rotational coupling with the spindle and for axial movement relative to the first component and the spindle, and is axially movable between a depressed position and a projected position. The cam interface is configured to correlate rotation of the first component with axial displacement of the second component.
