Embodiment Construction

[0062] figure 1 A top view of a front panel 10 of an operating unit 12 for an air-conditioning or heating system of a motor vehicle is shown. Also shown are three rotary regulators 14 for regulating temperature, air distribution and blast intensity. Furthermore, operating unit 12 also has various keys 16 . The three rotary actuators 14 also have stop devices, which serve on the one hand to maintain the currently assumed rotary position and, on the other hand, to provide an acoustic and tactile feedback of the adjustment to the person actuating the rotary actuators. With the help of Figures 2 to 11 The construction of the locking device according to the first exemplary embodiment is explained in detail.

[0063] Each rotary adjuster 14 has a rotary operating element 18 , which is mounted rotatably about an axis of rotation 20 . On the lower axial end side 22 , the rotary operating element 18 has a locking link 24 which extends on the end side along the circumference of the...

Abstract

The latching device for a rotationally or translationally movable operating element is provided with a resiliently mounted latching projection (32) and with a latching guideway (24) which is in sliding contact with the latching projection (32) and which has a plurality of latching depressions (26) with latching elevations arranged between them. The latching depressions (26) and the latching elevations (28) form a substantially corrugated latching path (30) along which the latching projection (32) slides during a relative movement between latching guideway (24) and latching projection (32). The latching projection (32) has a surface (44) which contacts the latching path (30) along at least one contact line (40, 42) running substantially transversely to the longitudinal extent of the latching path (30). When sliding along the latching path (30), the latching projection (32) experiences an upward and downward movement with periodic change of the orientation of its contact line (40, 42) with respect to the latching guideway (24). The surface of the latching path (30) has a change of inclination which follows the change of orientation of the contact line (40, 42) of the latching projection (32) during its upward and downward movement.

Description

technical field [0001] The invention relates to a locking device for a rotationally movable or linearly movable operating element. Background technique [0002] Operating units are used to manually operate electrical or electronic devices, which operating units have operating elements of different configurations. In addition to depressible push-button operating elements, sliders or similar objects are increasingly used as rotary actuators (ie, rotatable operating units), especially in motor vehicle operating units. In the case of rotatable operating elements as well as translationally movable operating elements, it is desirable to provide the person actuating the operating element with acoustic and / or tactile feedback regarding the adjustment of the operating element. The locking device has proven to be effective in this regard, and has the additional advantage that the actuating element automatically maintains the once-accepted adjustment position. Furthermore, the lockin...
