Definitions

  • the invention relates to a pot-shaped winding drum for a retractable and extendable telescopic antenna according to the type specified in the preamble of claim 1.
  • a telescopic antenna is already known (Hirschmann Automatic antennas AUTA 6000 EL), in which a toothed conveyor wire for the telescope is transported through a gearwheel connected to a worm wheel, the worm wheel being driven by a worm driven by a belt drive with an electric motor connected is.
  • the conveyor wire is wound up or unwound in the winding space of a non-driven winding drum.
  • a winding drum is also known (US Pat. No. 2,496,785), which is connected to an annular gear wheel, which faces a motor-driven drive wheel with the interposition of a conveyor wire.
  • the invention has for its object to develop a winding drum according to the preamble of claim 1 such that the gear means are simplified.
  • the components of a winding drum unit according to the invention are a winding drum 10, a coupling part 11, a wire guide part 12 and a gear part 13.
  • the substantially pot-shaped winding drum 10 is made in one piece and has a flat base part 14 which merges into a somewhat conical outer wall 15 and an inner wall 16 which is coaxial with this and has a smaller diameter.
  • the diameter ratio between the outer wall 15 and the inner wall 16 is chosen so that a winding space 17 remains free between the two walls.
  • the inner wall 16 carries a ring gear 20 in the edge region of its outer side 18 facing away from the base part.
  • the winding drum has on its open side a tubular extension 21 through which the coupling part 11 to be inserted into the interior 22 and to be firmly connected to the inside of the base 14 fits.
  • the wire guide part 12 consists of a flat ring 23 with a cylindrical projection 24 on the top, which fits loosely in the tubular inner wall 16 of the winding drum.
  • the lower leg 26 of the insertion opening 25 is followed by a deflecting wall 27 which runs obliquely upwards and opens into the flat ring.
  • the gear part 13 consists of a cylindrical pin 28 to which a worm wheel 29 is attached. At its end facing away from the worm wheel, the pin 28 merges into a pin 30 of smaller diameter.
  • the parts 10, 11, 12 and 13 are one-piece parts, preferably plastic injection molded parts.
  • the gear part 13 is connected to the coupling part 11 in a rotationally fixed manner and held axially immovably in the bottom wall 14.
  • FIG. 2 also shows a housing part 32 of the telescopic antenna, which accommodates the winding drum unit 33 shown in individual parts in FIG. 1.
  • the wire guide part lies in the housing in a rotationally secure manner, while the winding drum 10 is rotatably mounted.
  • the winding drum is driven by the worm wheel 29 and a worm 34 which is arranged on the shaft of an electric motor 35.
