Definitions

  • the invention relates to an auxiliary device for erecting capsized sails of windsurf boards with a line attached to the mast.
  • the object of the invention is to create an auxiliary device with which these forces, which must be very great at the beginning of the re-erection, can attack the sail more effectively.
  • the invention solves this problem by means of a tube or the like fastened to the mast foot, the free upper end of which is firmly connected to the mast by a cord of limited length and to a line on which the pull necessary for the straightening up can be exercised. It is thereby achieved that the pull exerted on the line initially acts on the upper end of the tube and this rises from the water by an amount which is limited by the length of the cord.
  • the length of the cord is preferably chosen so that when a pull is exerted on the upper tube end, the tube is at an angle of 30 to 50 ° to the mast.
  • FIG. 1 and 2 show a windsurf board 1 with a mast 2, a sail 3, a boom 4 and the auxiliary device according to the invention.
  • the auxiliary device has a tube 5 and a pull line 6.
  • the tube 5 is closed at the bottom with a bushing 7 and at the top with a bushing 8.
  • the mast 2 which is usually connected to the windsurfing board 1 by an elastic part 9 via two plastic parts 10 and 11, usually consists of a plastic tube which is conical upwards and over which the pocket 12 of the sail 3 is pulled. This pocket is fastened at the bottom with a cord 13 to the plastic part 11, which has a hole 14 running diametrically through the plastic part.
  • the lower bushing 7 of the tube 5 is also fastened to the mast with a part 13a of this fastening cord. This cord part 13a is through a bore 15 in this lower one Led out.
  • the course of the fastening cord is shown only by a simple representation of the two cord parts 13 and 13a. In reality, the connection of these cord parts would also be seen.
  • the upper part of the tube 5 is closed with a bushing 8 which has a longitudinal bore 16 and an eccentric transverse bore 17.
  • An elastic train preferably a rubber band 18 is in a bore 19 which secures the lower end of the tubular sleeve 7 and extends approximately between a third and a half of the tube length in the tube 5 upwards.
  • this elastic cable 20 is knotted with a cord 21 which extends outwards through the longitudinal bore 16 and, as can be seen, is fastened to the mast at the point 22. If a pull is now exerted on the upper end of the tube 5 via the line 6, which is fastened in the eccentric bore 17, then this pull is transmitted to the elastic pull 18, which stretches until the knot 20 is tightened strikes the lower stop end 23 of the socket 8. In this case, as can be seen from FIG.
  • the tube 5 assumes a position relative to the mast 2 in which the latter forms an angle ⁇ with the tube. If a pull is now exerted on the bushing 8 of the tube 4 with the line 6, this is transmitted to the mast point 22, as shown in FIG. It has been found that this allows the sail to be raised much more easily than without the auxiliary device, as shown in FIG. 4.
  • the auxiliary device significantly increases the angle ⁇ at which the tension is exerted on the masts.
