  • a possible adjustment can be a few millimeters, for example 1 mm to 5 mm.
  • the axis 14 together with the axle disc 15 is fixed at the bottom of the carrier 11 in the axial direction.
  • the drive plate 34 can in contrast be moved in the axial direction, wherein the rotationally fixed bearing with respect to the axis 14 is maintained, so that it is rotated in each case. By a spring this adjustment can be used just for resilient pressing up.
  • a finished operating device 10 shows a finished operating device 10, but at the same time a section of a hob 71.
  • the cover 63 of the operating device 10 is also part of a cooktop plate of the hob 71, as is well known.
  • a seal 66 advantageously made of rubber used in an opening 64 in the cover 63. It has an upper collar 67 which is wide and rests on top of the cover 63.
  • a lower collar 68 of the seal 66 is inserted through the opening 64 and abuts on the underside. This is to prevent liquid on the cover 63 between the cover itself and the seal 66 goes down.
  • the seal 66 has a detectable height above the cover 63, so that spilling over of liquid is difficult.
  • a rotary knob 70 is formed. It is designed for the rotationally fixed attachment to the axis 14 with its flattening, which is known in principle to the person skilled in the art.
  • the rotary knob 70 around the individual symbols 56 of the symbol disc 55 are arranged with the numbers or symbols, as they are mainly from the Fig. 6 can be seen. These are translucent, so that the corresponding symbols or numbers can be illuminated from below with LED and are visible as a light indicator through the cover 63 therethrough.
  • the operating device 10 is pushed out of a fitting position relative to the carrier 11 or moved linearly, so that the retaining lugs 26 engage under the retaining projections 12 in the end position.
  • the carrier 11 is slightly bent in the region of the bearing projection 23 until the bearing projection 23 engages in the bearing recess 13 and engages. In this case, there is an obvious strong stress on the components due to the deflection.
  • FIGS. 9 and 10 a further embodiment of an operating device 110 is shown, in which a bearing recess 113 is likewise provided in the carrier 111.
  • the axis 114 has in comparison to the representations of Fig. 5 to 8
  • a longer, not shown here bearing projection whose length advantageously corresponds exactly to the thickness of the carrier 111.
  • the above-described pushing or linear movement of the operating device 10 relative to the carrier 11 is not possible with such a long bearing projection. Therefore, the mounting is performed with a rotary motion, as will be explained.
  • the support frame 120 has downwardly extending guide pins 172, which are arranged on protruding arms. They are designed to engage in elongated holes 173 of the carrier 111.
  • securing projections 175 are again formed on protruding arms, which are downwards. They are recognizably beveled in the direction of rotation for the end position, so that they can more easily engage in securing recesses 176 of the carrier 111.
  • Fig. 11 is shown in plan view, as the operating device 110 is attached to the carrier 111 and thereby engages the bearing projection of the axis 114 in the bearing recess 113.
  • the guide pin 172 including slots 173 are provided, with the guide pins 172 are located at the left end of the slots 173 here. It can be seen that in this piecing position the retaining lugs 126 have not yet reached under the retaining projections 112 in the carrier 111. Likewise, the securing projections 175 have not yet been able to press into the securing recesses 176, since they are not yet over it.
  • a relative rotation is now performed in a second step after the attachment of the two parts to each other, for example, the control device 110 in the representation of Fig. 11 rotated clockwise relative to the carrier 111.
  • the guide pins 172 run along in the slightly curved elongated holes 173.
  • the retaining lugs 126 run under the holding projections 112.
  • the securing projections 175 engage in the end position in the securing recesses 176 and prevent turning back. This turning back is only possible by removing or canceling the securing projections 175, alternatively by their simultaneous lifting out of the securing recesses 176 out and at least certain rotation back into the attachment position, so they do not automatically engage again.
  • a lateral section of this configuration is not shown in addition, but it can be easily determined by the 6 to 7 to introduce.
  • the bearing projection on the axle 114 extends to the level of the underside of the carrier 111.
  • the additional bearing of the axle 114 is also made possible on the carrier 11, which is usually stable. If the upper storage is not only in the operating device 110, in particular on the in Fig. 6 illustrated intermediate bearing 46, but also possibly still arranged on the cover 63 Seal 66, lateral forces and lateral forces on the axis 114 can be very well absorbed by these bearings and are largely kept away from the drive plate 134.
