Abstract
A rotary controller selectively-disengageable locking knob assembly, having a hub having a longitudinal axis and an axial bore extending at least partially through the inner hub along the longitudinal axis, wherein the axial bore is configured to receive a shaft of the rotary controller arranged in or on a device surface. The assembly also includes a knob concentrically disposed about at least a portion of the hub, wherein the knob includes a first engagement arrangement. A post is threadedly engaged with the radial bore so as to secure the hub to the shaft of the rotary controller, and projecting radially outwardly through the radial slot, such that rotation of the knob induces a rotation of the hub via contact of the post with the radial slot. The knob is axially moveable on the hub to selectively disengage the first engagement arrangement from contact with a second engagement arrangement.
