Definitions

  • One of the steps in rigging a surfboard is to connect the boom to the mast of the rig.
  • the boom has a shaped piece on its mast-side end, which is essentially V-shaped or round and in the leg of which the fork ends are inserted.
  • mast rope a rope known as mast rope, in order to achieve a firm connection.
  • the surfer puts a stopper or similar knot around the mast with one end of the mast mast.
  • the object of the present invention is to provide a connection between the boom and mast of a rig, which is easier to handle and helps prevent possible kinking.
  • a device for connecting the boom and mast of a rig the device being non-positively connected to the mast-side ends of the boom, which is characterized in that it consists of two individual shaped pieces, each of which is fixed to a branch of the boom are connected and between them a free space for receiving the mast by at least 90 degrees close, furthermore that there are clamping means by means of which the two fittings can be releasably clamped together around the masts.
  • the two shaped pieces 1, 2 surround the mast 3 shown here in cross section.
  • Each shaped piece 1, 2 has a cylindrical recess 4, into which the fork ends 5 can be inserted.
  • the clamping surfaces 6 are shaped as segments of an inner cylinder wall and are somewhat extended on both sides of the device in the direction of the mast, whereby lips 7 are formed which can be braced over ribs for reinforcement.
  • the clamping surfaces 6 are with a non-slip, rubber provided elastic plastic material 10.
  • the two shaped pieces 1, 2 have holes 11 through which the starting bulkhead can be guided.
  • a flexible tab 8 is attached to one shaped piece and is guided around the mast 3 to be enclosed by at least 60 degrees.
  • a hook 9 is formed, on which a U-shaped clip 12 can be hung.
  • the lips 7 are largely enclosed by the tab 8 and the clasp 12, which are tensioned by means of a buckle 13.
  • the clamping clip 12 and the tab 8 together span the masts 3 to be clamped in by at least 180 degrees. The clamping force is thereby continuously distributed over the entire circumference of the mast 3.
  • the tab is advantageously made of metal and riveted to the fitting 2.
  • the two leg ends 15 of the U-shaped clip 12 are pivotally attached to the buckle 13.
  • the buckle 13 itself is designed so that it works according to the lever law. It is pivotably placed on a specially shaped support surface 20, which has a series of joint socket-like depressions 21.
  • the buckle 13 can be pivoted about the pivot point 16 formed by its joint head 22.
  • the distance between this fulcrum 16 and the attachment location 17th thereby forms a load arm, while the area between pivot point 16 and buckle handle 18 forms a power arm.
  • the clamping clip 12 passes the pivot point 16 as zenith in the closing direction of the buckle 13, the clip 12 comes to lie between the pivot point 16 and the buckle handle 18 when the buckle 13 is closed. This achieves self-locking, which effectively prevents the buckle 13 from opening independently.
  • the end 19 of the buckle handle 18 is flush with the boom 5, thereby preventing the buckle 13 from being inadvertently opened. This also reduces the risk of injury to the closed buckle 13.
  • a joint socket 21 for the part of the buckle 13 forming a joint head 22 is formed by each recess 21 of the bearing surface 20. Depending on the recess 21 in which this joint head 22 is placed, a more or less strong clamping or clamping force results. Since the two fittings 1 and 2 can be completely symmetrical, they can be produced using only one injection mold, which is also smaller and therefore cheaper than one for a conventional V-shaped fitting.
  • FIG 2 the embodiment shown in Figure 1 and already described is shown in perspective. It can be clearly seen that the clamping surfaces 6 on both sides of the device are somewhat extended by forming lips 7. As a result, the clamping handle is reinforced and the torsional stability compared to the mast 3 is increased. So that the lips 7 can better absorb the forces that occur, they can be reinforced with ribs.
  • the clamping surfaces 6 are also provided with a non-slip, rubber-elastic plastic material 10. This protects the mast 3 and the boom 5 can be moved somewhat relative to the mast 3 depending on the selected clamping force.
  • the device according to the invention allows the surfboard to be rigged up more quickly. Because the boom is divisible at the front, i.e. its two branches can be spread apart, it can simply be placed around the rig, or around the sail and masts, after which the device is clamped together using the buckle. In addition, the handling of this device is significantly easier than the handling of the mast rope, which now completely eliminated.
  • the surfer no longer needs to master the stopper stick or other suitable knots and can therefore no longer experience surprises on the water that can result from an incorrectly attached fastening knot. Even in the event of falls and other unusual movements by the surfer, the clean connection between mast 3 and boom 5 always remains. There is no longer any rope that could compress and damage the masts in such situations due to strong constriction. The contact surfaces twist less and their edges can no longer impress the masts. As a result, weakened areas on the masts can no longer arise and kinking is no longer possible for this reason.
