Definitions

  • the invention relates to a sword bearing for surfing sail boards, with a sword box inserted into the sail board, in which a sword that can be inserted from above is pivotably mounted with a handle protruding over the top of the board.
  • a sword bearing of this type known from DE 32 17 444 C2
  • the sword is pivoted during pivoting out and in about two bearing journals arranged on both sides of the sword with a common axis of rotation, which in guide and bearing grooves in the side walls of the lower part of a two-part sword case to sit.
  • the relatively large swivel range of the handle of the sword projecting over the top of the board, the swiveled-out position of which is predetermined on the basis of the size of the sail board, due to the uniaxial swivel mounting of the sword, means that the handle, when the sword is swiveled in, moves a position relatively far in the bow direction relative to the position of the swiveled-out sword occupies.
  • the forward position of the sword handle limits the rearmost position of the mast foot, which is adjustable in the longitudinal direction of the board by means of a slide that can be moved in a mast rail.
  • the limitation of the rearmost mast foot position due to the relatively far forward position of the sword handle when the sword is swung in has a negative effect on the speed of the surfboard on space sheet courses.
  • the invention has for its object to reduce the pivoting range of the handle of the sword of the generic sword bearing when swinging the sword out and in.
  • the sword bearing according to the invention brings about a considerable improvement in the sailing properties of a surfing sail board without worsening the handling of the sword with a reduced pivoting range of the sword handle compared to the known surfing sail boards.
  • the unchanged good handling of the sword is achieved by the double bearing of the new sword, which ensures favorable leverage, especially when the sword is unfolded, so that when the sword is unfolded due to the friction of the sealing lips on the underside of the sword box by the surfer to be applied by adults without difficulty Young people are controllable.
  • the speed of racing boards in particular can be increased by installing an appropriate insert plate with the guide and bearing grooves for the pivot pins of the sword, which enable the rearmost position of the mast base to be optimally shifted in the rear direction.
  • a sailing board 1 with a foam core 2 is provided with a recess 3 in the core, which receives a plastic-molded sword case 4 and is extended in the rear direction to receive a swung-in sword 5.
  • a mast rail 8 with a slide 9 which can be displaced in the longitudinal direction of the board is used for setting different positions of the mast base 10.
  • An outer bearing pin 12 in the area of the upper edge 13 of the sword and an inner bearing pin 14 offset from it are formed on the upper sword part 11, which in the longitudinal direction of the sword 5 with a distance a and in the transverse direction of the sword with a distance b from one another on one side of the sword upper part 11 are arranged.
  • Plastic rollers 15 are placed on the journals 12, 14.
  • an interchangeable insert plate 17 made of plastic is inserted from below, which latches with the side wall 16.
  • the insert plate 17 has two curved guide and bearing grooves 18, 19 for receiving the bearing pins 12, 14 of the sword 5 with the rollers 15.
  • the bearing grooves 18, 19 extend up to the top 4a of the sword case 4.
  • the kinematics of the sword bearing shown in FIG. 2 are as follows: When pivoting the sword 5 from position 5a to position 5b and pivoting the sword in the opposite direction, the two bearing pins 12, 14 form two variable pivot points 20, 21, and the sword 5 pivots about a variable ideal pivot point 22, which is characterized by the Intersection of the two standards 23, 24 on the tangents 25, 26 on the guide and bearing grooves 18, 19 in the variable pivot points 20, 21 in the respective position of the sword 5 results.
  • FIG. 1 The position of a handle 27 of a conventional, swiveled-in sword with a single-point swivel mounting shown in dash-dotted lines in FIG. 1 illustrates the position 6a of the handle 6 of the swiveled-in sword 5 that can be moved by the two-point swivel mounting.
