Patent ID: 6910827

Claim:
In combination, an actuating lever formed of a flat shaft and having a central axis, said actuating lever comprising a plurality of barb engagement surfaces extending laterally to the central axis, a knob defining a cavity having an opening for axially receiving the actuating lever, and a retainer disposed within the cavity for retaining the actuating lever therein, said retainer comprising a body comprising stakes and wings extending laterally relative to the body for supporting the body within the cavity and adapted to springingly deflect in response to axial insertion of the actuating lever to cause the stakes to engage the cavity surface, thereby securing the retainer within the cavity, said retainer further comprising a cantilever arm attached to the body at one end and extending axially to a front end adjacent the opening and adapted to springingly deflect in response to axial insertion of the actuating lever into the cavity, said cantilever arm further comprising barbs for engaging the barb engagement surfaces of the actuating lever to retain the actuating lever within the cavity.
