Definitions

  • the invention relates to a device for the articulated fastening of a mast foot to a sailing board.
  • Known joints generally consist of a flexible plug made of rubber or a similar flexible material.
  • the invention has for its object to provide a device for the articulated attachment of a mast foot to a sail board, which at the same time prevents the risk of injury by pinching body parts between mast and sail board with particularly easy mobility of the mast.
  • the invention provides that a double ball socket joint is arranged between a pin to be attached to the sail board and a socket to be connected to the lower end of the mast, that the double ball socket joint consists of two ball socket joints arranged one above the other and that the range of motion of the socket relative to the pins overall is limited to essentially 180 degrees by at least one stop.
  • the essential technical progress can be achieved that an extremely robust, stable, by mechanical stresses highly resilient, smooth joint was created, which also reliably prevents body parts such as arms and legs from being accidentally caught between the mast and the sail board. It is namely ensured according to the invention by a stop that the mast can not be turned so far that it comes into contact with the sail board.
  • the stops are preferably arranged in such a way that there is always sufficient space between the mast and the sail board to prevent crushing of the arms or legs.
  • the mast can be pivoted with practically no resistance to the desired control movements relative to the sail board.
  • the joint according to the invention can also be loaded with extremely large forces up to approximately 200 kp without the risk of damage.
  • the mast can be guided very easily on the one hand within the desired range of movement due to the limitation of the range of movement by means of a stop and, on the other hand, never move beyond the permissible range even on uncontrolled movements and strike against the sail board.
  • the desired distance at maximum deflection of the mast between the sail board and the mast can be determined by appropriate arrangement of the stops. If necessary, this distance could also be changed by changing the height of the double spherical shell joint relative to the sail board.
  • the device according to the invention is also practically maintenance-free and ensures perfect functioning even over very long operating times.
  • a pin 10 which is intended for attachment to a sail board, is pivoted by 90 degrees relative to a connecting piece 11, which can accommodate a mast.
  • the connector 11 is connected to the pin 10 via a double spherical shell joint 12.
  • This double spherical shell joint 12 essentially has two spherical shell joints 13 and 14 which are arranged in series between the socket 11 and the pin 10.
  • the spherical shells of the two spherical shell joints 13 and 14 are arranged within a sleeve 17.
  • the individual components can be seen, from which the invention Device exists. It can be seen from this illustration that the double ball socket joint designated in its entirety by 12 essentially comprises those components which are identified by the reference numerals 13 to 31.
  • the nozzle 11 can be pivoted between the extended position shown in FIG. 3 and the angled position illustrated in FIG. 1 with respect to the pin 10, namely in a radius of action of 360 degrees. This means that the nozzle 11 in the position shown in FIG. 1 can be rotated as desired about the axis defined by the pin 10.
  • the stop surface 23a which is formed on the ball pin neck 23, lies on the stop 16, which is formed on the projecting edge 27 of the hollow cylinder piece 25.
  • the core 31 When assembled, the core 31 is with its. External threads are screwed into the two hollow cylinder pieces 24 and 25 in such a way that the inner end edges of these two hollow cylinder pieces 24 and 25 meet.
  • a bearing shell is formed for the joint ball 20 or 21, specifically by the projecting edge 26 or 27 of the hollow cylinder piece 24 or 25 on one side and the concave recess 29 or 30 of the ring 28 on the other hand, wherein the ring 28 is slidably mounted within the core 31 in the sliding fit and is held between the two joint balls 20 and 21.
  • the two ball studs 18 and 19 and the core 31 are made of a metal that is resistant to salt water, and the remaining parts of the device according to the invention are made of an unbreakable plastic material that is resistant to salt water and has high tensile strength.
  • an unbreakable plastic material that is resistant to salt water and has high tensile strength.
  • polytetrafluoroethylene or other suitable plastic material could be used.
  • the protective sleeve 32 can be formed, for example, as a bellows made of a rubber-elastic material such as a plastic material.
