Abstract
The invention relates to an operating device (1) comprising a rotatable crank drive which can be actuated by repeatedly pressing and releasing a push-button (4). The push-button (4) is thus alternately fixed in an operating position, i.e. the out position, and a locking position, i.e. the pressed-in position. A rotatable locking ring (9) which can be axially displaced in an elastic manner and the housing (8) of the operating device (1) comprise crank elements (10, 11) which are alternately distributed around the circumference, and in which the push-button (4) can be securely locked in a precise position.
Claims5
Operating device (1) for a flush operating knob (4) with a locking device for the axial locking and unlocking of the operating knob (4) that is extendable under spring load by means of a link guide, especially for the rotary switch of an automobile,
- characterized in that the link guide is embodied as a multiple toothed, circumferential link drive,
- that a body (8) of the operating device (1), and a locking ring (9) that is axially fixed and pivoted on the operating knob (4) have successively arranged, circumferentially distributed link elements (10 and 11), in which the operating knob (4) can be axially locked.
Operating device according to one of the previous claims,
- characterized that the fixed link elements (10) of the body (8) continuously extend to an exterior body edge of the hollow-cylindrical wall,
- that the operating device (1) can be attached to an assembly area in an instrument panel (21) in its locked position, and that the axial spring-loaded operating knob (4) in its unlocked position can be pushed a stop shoulder (22) of the instrument panel (21) against a collar-like stop (20).
