Definitions

  • the invention relates to a lip seal made of plastic, in particular for the lower end of the sword case of a surfboard.
  • Sealing lip profiles for the sword case have also already been screwed into the board body.
  • the screwing in of the sealing lips brings on the one hand the advantage of the easy interchangeability of sealing lips in need of renovation, but on the other hand shows the disadvantage that the flow conditions under the board are adversely affected by the screw heads protruding above the underwater ship.
  • the invention has for its object to develop a lip seal for the sword case of surfing sail boards, which does not detach from the board body, does not affect the flow conditions and is easily replaceable in the event of damage.
  • the invention is characterized in that the object is achieved in a simple and expedient manner. Furthermore, the lip seal offers optimal rigidity against water pressure and is almost completely sealed when the sword is folded in and out.
  • the cover strip with the sealing lip is characterized by a streamlined surface. Finally, the cover strip is very inexpensive to manufacture, since the clamping zone is made of hard plastic, e.g. Polyvinyl chloride, and the sealing lip made of soft plastic, e.g. Polyurethane, with an appropriate design of the extrusion die of an extruder, can be extruded from these relatively inexpensive materials at the same time and the two different plastics firmly bond to one another during curing.
  • the lip seal for the sword case (not shown) of a surfing sail board (1) has two support bars (3) let into the board body on both sides of the sword case opening (2) as well as two cover bars (5), which are designed as terminal bars and which close with the profile (4) of the underwater ship, for clamping in the carrier strips (3).
  • the cover strips (5) consist of a flat extruded profile that has an outer Clamping zone (6) made of a hard plastic, such as polyvinyl chloride, and an inner, a sealing lip (7) forming zone made of elastic plastic, such as polyurethane.
  • the two sealing lips (7) of the lip seal form an elastic, tight closure of the sword case opening (2) in the folded (8 ⁇ ) and the unfolded position (8 ⁇ ) of the sword (8).
  • two vertical clamping webs (9, 10) with a hook-shaped cross section are arranged, which when the cover strip (5) is clamped into the carrier strip (3) behind the hook-shaped legs (11, 12) of the support bar (3) designed as a U-profile.
  • obliquely inward-facing guide surfaces (13) for corresponding outward sliding surfaces (14) are arranged on the clamping webs (9, 10) of the cover strip (5) such that when the cover strip (5 ) in the carrier strip (3) the clamping webs (9, 10) of the cover strip (5) are first pressed inwards and then spring open again and hook behind the hook-shaped legs (11, 12) of the carrier strip (3).
  • the carrier strips (3) which are made of a hard plastic, e.g. Polyvinylchloride or aluminum are screwed to the sword case and screwed outside of the sword case onto plastic blocks (15) glued into the surfboard (1).
  • a hard plastic e.g. Polyvinylchloride or aluminum
  • cover strip can be removed and replaced by simply loosening the clamping lock between cover strip (5) and carrier strip (3).
  • the carrier strips (3) can be injection molded onto the lower part of the sword case made of plastic.
