Definitions

  • the invention is based on an antenna for automobiles with in the preamble of claim 1 specified features.
  • Such an antenna is on the market. It has a foot section with an obliquely upward rod-shaped Radiators for radio reception. At the bottom of the foot section are medium provided for fastening the foot part on the roof of the body of an automobile.
  • the body panel has a hole in which a short extension provided on the underside of the foot part is inserted.
  • a tensioning device from below on the extension, which cooperates with the underside of the foot part the body panel between the underside of the foot section and the tensioning device clamps.
  • the foot section has a housing with a base plate.
  • the Housing has a lower edge, which protrudes downwards over the base plate and has a contour which is adapted to the contour of the body panel.
  • an elastomeric seal along the bottom of the housing provided, which in a relaxed state down over the lower Edge of the housing protrudes. By clamping the foot section on the body panel the seal is compressed.
  • the present invention has for its object to show a way how can be ensured with such an antenna with an eccentrically located attachment point in the simplest and cheapest possible manner that the inner seal is evenly compressed in the assembled state and between the lower edge of the housing of the foot part and there is no gap in the body panel or at most a uniformly wide gap.
  • Such a buffer is particularly suitable for an antenna in which the seal on the underside of the base part of the antenna a constant length Cross section.
  • a second solution to the problem is the subject of claim 5.
  • a seal is provided instead of a separate buffer, in which the cross-section is not the same over its length, but in which the cross section of the seal in the area between the extension and the nearest Apex of the lower edge of the housing is so much larger than between the extension and the distant apex that already the Counterforce caused by the compression of the seal in its section between the longitudinal axis of the extension and the nearest vertex that counterbalance which is balanced by the upsetting of the Seal in its section between the longitudinal axis of the extension and the distant apex is generated, so that an uneven gap between the body panel and the lower edge of the housing is avoided.
  • the antenna shown in Figures 1 and 2 has a foot part 1, which a Has base plate 2 made of metal and a hood 3 made of plastic, in which the Base plate 2 is inserted so that the lower edge 6 of the hood 3 all around little protrudes downward over the base plate 2.
  • the contour of the edge 6 is adapted to the contour of the body panel 4 on which the antenna is attached shall be.
  • the hood 3 has an extension 22 with a threaded bush into which an antenna rod 24 is screwed, which one at its lower end has threaded bolts matching the threaded bushing.
  • the antenna rod 24 runs with a strong inclination against the base plate 2 of the foot part 1
  • a first elastomeric seal 5 is provided, which is supported on the underside of the base plate, rests on the edge of the hood 3, protrudes over the edge of the hood 3 in a relaxed state and has a contour has which the contour of the body panel 4 is adapted, on which the Seal 5 comes to rest.
  • the lower edge 6 of the hood 3 and also the seal 5 are oval in plan (see Figure 2).
  • the metallic base plate 2 To attach the foot part 1 to the body panel 4, the metallic base plate 2 an extension 7 in the form of a sleeve, which itself from the flat base plate 2 to beyond the lower edge 6 of the hood extends vertically downwards.
  • This extension 7 is through a bore 8 in Body sheet 4 inserted and fastened by means of a clamping device 9.
  • the Clamping device 9 consists of an outer sleeve 10, which over the sleeve-shaped Extension 7 is pushed and a ground contact ring at its upper end 11 carries, which tapered, against the underside of the body panel Has 4 directed projections 12.
  • the outer sleeve 10 is by means of a Screw 13, which is turned into an internal thread of the extension 7, or by a nut, which is turned on an external thread of the extension 7, pressed against the underside of the body panel 4, the projections 12 act with high pressure on the underside of the body panel 4 and there establish a reliable electrical ground contact.
  • tilting is caused by a Counteracted buffer 19, which in the area between the extension 7 and the nearest vertex 15 and is made of an elastomeric material, which is harder than the elastomeric material of the seal 5.
  • the buffer 19 is developed another counterforce 27, which together with the counterforce 25 Counterforce 26 compensated and thus ensured that the gap between the lower edge 6 of the hood and the body panel 4 is uniformly thin or even practically disappears completely.
  • the seal 5 can be in the area between the extension 7 and the nearest vertex 15 are greatly widened, as shown in Figure 3. Otherwise the example according to FIG. 3 is correct with the Example according to Figures 1 and 2 match.
  • a dome 20 is provided, which starts from the base plate 2 and protrudes downward beyond the lower edge 6. He serves in one to him to engage a suitable second hole in the body panel 4 and ensure that the antenna on the body panel 4 is fixed non-rotatably.
  • the mandrel 20 and the extension 7 are together from a second elastomer Surround seal 21, which preferably consists of the same material like the first seal 5.
  • FIG. 4 shows a practical example of a foot part 1 of an antenna of the type shown in Figures 1 and 2 in a plastic oblique view.
  • FIG. 4 is the one that slopes upwards Extension 22 can be clearly seen, which has a threaded bush 23, in which the antenna rod 24, not shown in Figure 4 can be screwed.
  • an outer sleeve 10 ( Figure 1) is pushed onto the extension 7 and with a screw to be tightened firmly against the underside of the body panel clamped, as described with reference to Figure 1.
