Definitions

  • the invention relates to a lip seal made of plastic for the lower end of the receiving opening for the sword case and the sword, especially in surf sail boards, with one on each side of the opening for receiving the sword case and the swung-in sword, flush with the profile of the underwater fastening strip hard plastic and a sealing lip made of elastic plastic together with this as an extruded profile, the sealing lips forming an elastic closure of the receiving opening for the sword case and the sword, as well as with a carrier strip made of plastic embedded in and fastened in the board body on each side of the receiving opening for clamping a fastening strip with a sealing lip.
  • the invention has for its object to develop a lip seal for the sword case and the receiving opening for the sword in surfboards with an improved sealing effect compared to the generic lip seal.
  • the lip seal according to the invention is completely sealed due to its optimal rigidity against water pressure when the sword is swung in and out.
  • the fastening strip with the sealing lip has a streamlined surface.
  • the fastening strip designed as a clamping strip with the sealing lip can be produced very inexpensively, since the fastening strip 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 5 inserted on both sides of the receiving opening 2 for the sword case and the folded sword 3 into the board body 4, as well as two fastening bars 7 with an elastic that form the terminal bars 6 of the underwater ship and are designed as terminal bars Sealing lip 8 for clamping onto the carrier strips 5.
  • the fastening strip 7 is designed as an L-profile.
  • a short, vertically bent clamping leg 11, 12 is formed on each of the end edges of the long 9 and the short leg 10 of the fastening strip 7.
  • the sealing lip 8 adjoining the long leg 9 of the fastening bar 7 is formed on its long side facing away from the fastening bar to form a rounded sealing edge 13 which merges into an elastic support leg 14 which is directed obliquely upwards and which joins the end edge of the short leg 10 of the fastening bar 7 is scheduled.
  • the support leg 14, which is stiffer than the sealing lip 8, has a greater thickness 15 than the sealing lip.
  • One fastening strip 7 each made of hard plastic, e.g. Polyvinyl chloride, and a sealing lip 8 and a support leg 14 made of an elastic plastic such as polyurethane are produced together as an extruded profile.
  • hard plastic e.g. Polyvinyl chloride
  • sealing lip 8 and a support leg 14 made of an elastic plastic such as polyurethane
  • the support bar 5 is designed as a U-profile with two short legs 16, 17 and a connecting web 18.
  • the leg 16, which is attached to the web 18 at right angles, has an extension 19 projecting beyond the connecting web 18 and a shoulder 20 at its free end.
  • the other leg 17 of the carrier strip 5 is bent slightly inwards, and the connecting web 18 has a shoulder 21 in the transition region to the oblique leg 17.
  • the carrier strips 5, which consist of a hard plastic such as polyvinyl chloride, are glued to the sword case and glued into the board body 4 outside the sword case.
  • the sealing lip 8 forms, together with the support leg 14 and the short leg 10 of the fastening strip 7, an elastic hollow profile strip 23, the stiffness of which is less in the extension direction a of the sword 3 than in the folding direction b of the sword.
  • This mode of operation of the sealing lip 8 integrated in the hollow profile strip 23 ensures that the two sealing lips 8 of the lip seal form an elastic, tight closure of the opening for receiving the sword case and the sword 3 in the folded 3 'and the unfolded position 3' of the sword 3, the sealing effect of the lip seal is ensured by the stiffening of the sealing lips 8 with the aid of the support legs 14 even when the water pressure is high on a strong swell on the underwater ship.
  • the reduced stiffness of the sealing lip 8 in the extending direction a of the sword 3 guarantees a medium smoothness of the sword 3, so that the hand force required for unfolding the sword can be mastered by any surfer, and that when folding in the sword due to the greater rigidity of the sealing lips 8 in Folding direction b increasing actuation force can be easily applied by any surfer due to the possibility of handling the sword with the foot.
  • the fastening strip can be removed and replaced by simply loosening the clamping lock between the fastening strip 7 and the carrier strip 5.
