Rotary knob assembly

摘要

A rotary knob assembly and methods for forming and controlling friction effecting features of the knob assembly are disclosed. The knob assembly includes a mounting structure and a knob. The knob is rotatably coupled to a bezel of the mounting structure. The knob includes a stabilizer, a guide member, and a retainer having a patterned surface. At least a portion of the stabilizer is disposed between the bezel and the retainer to maintain an axial position and a radial position of the knob. A detent formed on the guide member cooperates with a patterned surface of the retainer to provide a haptic feedback to a user.

主权项

1. A method for forming a knob assembly comprising the steps of:
(a) providing a first cavity insert for a mold assembly; (b) providing a first inner core insert for the mold assembly; (c) providing a first pair of outer core inserts for the mold assembly; (d) positioning the first cavity insert, the first inner core insert, and the first pair of outer core inserts to form a first mold cavity within the mold assembly for receiving a molten material therein; and (e) introducing the molten material into the first mold cavity to form a stabilizer of the knob assembly, wherein the first cavity insert, the first inner core insert, and the first pair of outer core inserts are at least one of modifiable and replaceable, and wherein the first cavity insert, the first inner core insert, and the first pair of outer core inserts include a groove and a protuberance configured to form friction affecting features of the knob assembly.
