  • Knob assembly
    Patent number: 5430249
    Abstract: A self-retaining knob assembly (200) includes a housing (150) and a hub (120). The housing (150) has a cavity(157) for receiving a key (135) and a rotation track (160) about the cavity (157). The hub (120) has an integral key (135) and is rotatably mounted within the cavity (157) and within the rotation track (160). While being mounted, the key (135) is guided into the rotation track (160) by a guide member (266) integrally located on the housing (150). The housing (150) has retaining members (261,262) which cooperate with the key (135) to substantially restrict the removal of the key (135) from within the cavity (157) after the key (135) is mounted.
