ABSTRACT:
A knob assembly (22) for a door (20) includes a spindle (30) and a latch (108) in communication with the spindle (30) and extendable from an edge (132) of the door (20). An inner knob portion (36) is secured to the spindle (30), and an outer knob portion (38) faces the inner knob portion and freely rotates on the spindle (30). A lug (102, 104) projects from a second surface (106) of the outer knob portion (38) for engagement with a notch (58) formed in a first surface54of the inner knob portion (36). The outer knob portion (38) is selectively operable to positively engage the lug (102, 104) with the notch (58) for enabling rotation of the spindle (30) in response to rotation of the outer knob portion (38) to move the latch (108) from a normally latched position (110) to an unlatched position (146).
