Definitions

  • the invention relates to a swivel joint according to the preamble of claim 1.
  • a swivel joint is known from FR-OS 25 31 029.
  • the sword can only be pivoted with difficulty after a short period of use in the known sailing surfboard .
  • the rubber knobs act like a trap for dirt particles which are washed against the rubber knobs when water passes through the narrow gaps between the sword and the sword case walls. The same applies to sand and gravel particles, which can get into the mentioned narrow gaps when pulling the sailing surfboard over the beach. These foreign particles also hinder the swiveling of the sword.
  • a further pivot bearing for the sword of a sailing surfboard which has a swivel joint serving as a fixed bearing axis, which forms a unit with the sword in the assembled state.
  • the known swivel joint has two bearing shells which are flanged to the sword from both sides and screwed together. The sword can be pivoted against the friction and clamping forces of the two bearing shells.
  • the swivel joint with guide ribs on both sides is inserted into corresponding longitudinal grooves in the sword case, which extend from the top of the board to beyond the middle of the sword case height.
  • the guide webs are provided with friction blocks, which exert friction and clamping forces against the longitudinal grooves.
  • the reaction forces occurring on the sword are, however, only insufficiently transmitted to the sail surfboard via the bearing shells of the known swivel joint, since the elastic friction blocks represent the only points of contact between the swivel joint and the sword box.
  • These reaction forces are considerable under certain circumstances, since the swung-out sword is subjected to bending in every angular position by the water flow transversely to the longitudinal direction and is additionally subjected to torsion in the longitudinal direction because the course apparently driven, especially when crossing, is not due to the drift and possible water flow corresponds to the course actually driven over ground.
  • the object of the invention is to ensure, in the case of a swivel joint of the type mentioned at the outset, an undisturbed function with regard to reliable locking and easy pivoting even during long operation.
  • FIGS. 1 and 2 show, in the case of the swivel joint according to the invention, the bearing lugs (n) of the slide rings (c) firmly connected to the sword are rotatably guided in the corresponding recesses (j) of the bearing shells (a), (b).
  • the transverse forces that occur on the sword as a result of the water flow are directed onto the board via the sliding surfaces (k / o) of the sliding rings or bearing shells (a), (b).
  • Ring seals (d) are used to seal the bearing, which are in contact with the sealing surfaces when the adjusting screw (i) is tightened (p) of the slide rings (c) and protect the entire mechanism from dirt.
  • the bearing shells (a), (b) are pulled against the slide rings (c) by means of the adjusting screw (i), which connects the two bearing shells inserted in a correspondingly larger hole in the blade.
  • a spacer sleeve or other suitable measures e.g. B. pin (f) / stump (r), thereby preventing the bearing shells (a), (b) from being pulled too tightly against one another.
  • a dowel pin (h) prevents the bearing shells from rotating against each other.
  • the frictional resistance of the swivel joint is determined by the ring seals (d), which are pressed against the sealing surfaces (p) with the help of the adjusting screw (i) in such a way that the sword is not automatically pivoted backwards by the water flow.
  • Clip elements (q) within the swivel lock the sword in one or more positions, the end positions of the sword being predetermined by stops, which can also be located within the swivel.
  • the sword is pushed together with the trapezoidal swivel from above into a corresponding recess on the board body.
  • a slight jerk locks the swivel in the board due to conical static friction.
  • the mechanics of the swivel joint are independent of the corresponding recess in the board body. With the exception of the end positions (rubber buffers), the sword does not touch the sword case when swiveling in and out.
  • the trapezoidal recess is only responsible for the adjustment of the bearing shells and the secure hold of the swivel joint. Farther it serves as an abutment for absorbing the torque that occurs on the bearing shells when the sword is pivoted in and out.
  • the bearing diameter (y / n) or diameter of the sliding surfaces (k / o) is chosen as large as possible.
  • the slide rings are screwed or glued to the sword.
  • the necessary bearing attachments (n), clip elements (q), sliding (o) and sealing surfaces (p) can be integrated, so that the sliding rings are not required as individual parts.
  • the clip elements (q) can also be located in the bearing shells, so that they snap into the corresponding recesses (m) of the slide rings or the sword.
  • the trapezoidal shaft in the board body is equipped with vertical webs so that any dirt that accumulates between the bearing shell and the shaft can be washed out by the water. Removing the sword is not affected by stuck dirt.
  • the locking of the hinge can be done by measures such. B. additionally screw to the board body or tensioning lugs to prevent the bearing from loosening automatically.
  • the clearly defined storage enables the sword to be operated automatically by means of a motor, so that the sword knob, which normally protrudes above the deck, could be dispensed with.
