Definitions

  • the invention relates to a rotary knob for an electric operating device with a lighting device, with a hollow handle portion having a translucent portion and a light source that emits light in the hollow portion of the handle portion.
  • knobs are often used in vehicle construction and there in the automotive electronics.
  • the lighting device is used to make the switch position even during darkness, whereby differences in the day and after design of the switch can be present.
  • the knobs have on their surface a light exit area, which then serves as a pointer marker for the setting of the control unit.
  • a light guide which forwards the light from a light source in the direction of the light-transmissive areas or light exit areas. From the DE 198 34 347 for example, a rotary knob for an operating device is known, in which the light which is emitted by a light source is forwarded by means of a light guide body in the interior of the rotary knob to the light exit areas.
  • the light-permeable region in the grip part of the rotary knob is exposed via a specially designed light exit region, which can be formed on the light guide.
  • the pointer mark on the handle part is thus indirectly illuminated by means of a light source and the light guide.
  • Such a knob is in the DE 35 35 381 disclosed.
  • the light guide is arranged here directly in the knob and has a connection socket for the light source.
  • the terminal base is made of a transparent material. He is a light guide formed, which ends with its surface in an opening of the opaque hood. If light is emitted by means of the light source, the surfaces are brightly visible on the visible side of the hood.
  • the invention is based on the object to develop a knob that optimally exploits the luminous efficacy of the bulb, which is produced with minimized manufacturing and assembly costs, which has an independent of the light source, swivel handle part and its translucent area in every turning and swiveling position with the same intensity lights.
  • the light is generated by means of a light source and passed through a hollow cylindrical reflector on the translucent area, wherein the reflector extends from the bulb to the hollow portion of the handle portion.
  • the inventive design of a knob can be dispensed with the light guide inside the knob and the knob can be produced with minimal production costs and correspondingly lower production costs.
  • Another advantage resulting from the elimination of the light guide, is that the handle portion of the knob can be arranged pivotally.
  • FIG. 1 shows the perspective top view of a rotary knob 1 according to the invention.
  • the rotary knob 1 consists of an opaque handle part 2, a handle part connected to the base part 3 and a rotary knob housing only partially shown 4.
  • the handle part 2 has a disc-shaped lower portion 5 and arranged above it, diametrically extending over the disc-shaped portion 5, elongated area in the form of a survey 6. In a radially outer end of the survey 6, a translucent area 7 is formed in the survey 6.
  • the handle part 2 and the base part 3 are rotatably mounted in the direction of the arrow P relative to the rotary knob housing 4.
  • Such a knob 1 may, for. B. as a rotary switch for an electric sunroof in a motor vehicle use.
  • Figure 2 shows the perspective view of a knob 1 without handle part 2, so that the base part 3 with the preferably integrally formed thereon reflector 8 is visible.
  • the base part 3 is preferably made of polyoxymethylene (POM). In this case, white-colored POM is preferably used.
  • This colored plastic (POM) has a high degree of reflection, so that the substantially hollow cylindrical surface 9 of the reflector 8 need not be additionally coated, which in turn has a positive effect on the manufacturing cost.
  • In the annular groove-shaped recess 10 of the base part 3 further components, such as return springs, can be used.
  • On the outer peripheral surface of the base part 3 retaining pin 11 are simultaneously integrally formed for receiving the handle part 2.
  • the position of the luminous means 12 is shown in FIG.
  • the handle part has a disc-shaped structure in the lower region and is made tapered in the upper region 6, so that the operator can easily grasp the knob 1 and turn.
  • extensions 13 are formed which can be pushed over the retaining pin 11, so that the handle part 2, as shown in Figure 4, can be pivoted in the direction of the arrow F.
  • the handle part 2 pivots about the receiving pin 11 of the base part.
  • the grip part 2 is made hollow and the umbrella-shaped reflector 8 extends from the bulb 12 into the hollow region 14 of the grip part 2.
  • the reflection surface 9 forms the shape after the section of a hollow cylinder, which forwards the light umbrella-shaped.
  • the light rays 15 emitted by the light source 12 are reflected beyond the hollow cylindrical region 16 of the reflector out of the reflection surface 9 in the direction of the translucent portion 7 of the handle part 2, bundled and forwarded targeted, while angle and shape of the reflective surface 9 are the requirements accordingly variable.
  • the knob 1 is preferably made of plastic.
  • Preferred plastics are thermoplastic acrylonitrile-butadiene-styrene polymers (ABS) or ABS / polycarbonates (ABS-PC) or polyamide (PA).
  • the knob housing 4 is preferably made of polyamide (PA) and the handle part 2 is preferably made of ABS or ABS-PC.
  • the translucent region 7 of the grip part 2 is preferably made of the transparent plastic polycarbonate (PC).
  • PC transparent plastic polycarbonate
  • the knob 1 made of plastic may also have a painted surface.
  • the entire handle part are made of a translucent material, wherein the subsequently translucent acting area is masked before painting.
  • the upper part can also be completely painted in a first step and the translucent area 7 can be subsequently exposed by means of a laser engraving.
  • the maximum light output of the bulb 12 is forwarded via the reflector 8 to the translucent area 7. It is also clear that the still existing spread of the light illuminates the translucent area 7 in any pivoting position with full intensity. In contrast to the light guides in which the light is scattered on exit, in the inventive focusing of the light by the reflector 8, the light beams are focused and are thus for homogeneous fluoroscopy of the translucent area 7 available.
  • the translucent region 7 is preferably arranged at the radial end of the grip part 2.
  • the translucent region 7 can be a simple geometric shape, such as a circle or a rectangle, or it can be in the form of a symbol that identifies the intended use of the rotary knob.
  • the application of the invention is not limited to the automotive technology, the invention can also be used in the field of electronics and control technology, such as on test equipment.
