Definitions

  • the balls holder may comprise a ring part arranged around the rotary cylindrical body portion.
  • the balls holder may comprise a plurality of two lowers arms extending vertically from the ring part along the rotary cylindrical body portion, each lower balls being retained between two lower arms by means of bumps, such that each of two lower arms forming a lower ball cage.
  • the balls holder may comprise a plurality of two uppers arms extending from the ring part in a vertical direction along the rotary conical body portion, each upper balls being retained between two upper arms by means of bumps, such that each of two upper arms forming an upper ball cage.
  • the outer surface of the rotary body may comprise a plurality of uniform grooves extending in the vertical direction along the outer surface of the rotary body, regularly arranged around the outer surface of the rotary body and in direct contact with the plurality of upper balls and/or the plurality of lower balls; such that the rotary body comprises a wavy surface providing haptic effect while the knob is rotationally operated.
  • the plurality of uniform grooves may be arranged on the outer surface of the rotary cylindrical body portion such that said plurality of uniform grooves is in direct contact with the plurality of lower balls.
  • the rotary knob 10 comprises along a vertical axis V an upper cap 12 configured to be rotated by a finger of an operator about a rotational axis A, and a rotary body 14 configured to rotate about the rotational axis A.
  • the rotational axis A corresponds to the vertical axis V.
  • the upper cap 12 is configured to be attached at the top end of the rotary body 14.
  • the rotary knob 10 further comprises a detent ring 16 configured to be mounted at the bottom end of the rotary body 14 and comprising teeth for angular position detection of the rotary knob 10.
  • the detent ring 16 is configured to be snapped with the rotary body 14.
  • the rotary knob 10 further comprises a rotary detection system (not shown) cooperating with the teeth, as for instance light barrier system.
  • the balls holder 22 comprises a plurality of two uppers arms 54 extending from the ring part 50 in a vertical direction along the rotary conical body portion 28, in the direction of the large end of the rotary conical body portion 28, each upper balls 24 being retained between two upper arms 54 by means of bumps, such that each of two upper arms 54 forming an upper ball cage.
  • the bumps of each upper cage are oriented to the nest of the upper cage.
  • the space inside each upper cage, or nest of the upper cage, is a bit larger than each upper ball 24 diameter such that each upper ball 24 is free to rotate inside the upper cage.
