  • Conformed control knob for fingertip operation of a manipulating lever
    Patent number: 5386935
    Abstract: A conformed control knob (23) is mounted to a manipulating lever (22) of an apparatus (20) having an arm (21) to be operably controlled by the manipulating lever (22). Through manual manipulation of the control knob (23), the arm (21) can be controlled for proportional precision movement. The control knob (23) includes an upwardly facing substantially planar support surface (25) formed for supporting at least one fingertip (26) of an operator's hand thereon, and includes a recess (27) formed therein to receive the fingertip (26). The support surface (26) is sufficiently cupped and the manipulating lever (22) is sufficiently biased upwardly toward the fingertip (26) to transmit both lateral and vertical movement of the operator's hand to the manipulating lever (22) for fingertip control thereof.
