Definitions

  • the invention relates to a plug sword arrangement for a standing sail device, with a sword box and a plug sword guided therein, a bearing being provided in the side walls of the sword box for a pin projecting from the plug sword and the length of the lower slot opening of the sword box being greater than the width of the plug sword.
  • a plug-in sword arrangement is known from DE-A 2 738 070.
  • a standing sail device essentially consists of a boat hull, a rig and a plug sword.
  • the rig usually has a mast base with a joint, a mast, a boom and the sail.
  • the rig is placed in the so-called mast track and the plug-in sword in the sword case, whereby the mast base together with the mast track ensures that the rig can be detached from the hull at any time.
  • the mast track can be designed as a groove or blind hole or the like in the hull.
  • the plug sword is usually arranged behind the mast, for which purpose a sword box is provided behind the mast track arranged in the longitudinal center plane, which forms a longitudinal slot going through the hull.
  • the plug-in sword is pushed through this longitudinal slot and then protrudes downwards out of the hull.
  • the control principle of the dock sail device is based on the shifting of the sail pressure point in relation to the lateral center of gravity of the hull with a sword during sailing. Due to the articulated arrangement of the rig on the hull, the sail pressure point can be moved by tilting the mast forward or backward. In addition, several mast tracks arranged one behind the other can be provided, so that the sailor can choose the suitable mast track depending on the wind strength.
  • the lateral center of gravity of the hull can be changed by adjusting the lateral center of gravity of the plug-in sword. To this end, folding swords can be used to a limited extent, which are tiltably mounted in the sword case and, by tilting backwards, shift the lateral center of gravity of the sword slightly to the rear. At the same time, however, the lateral center of gravity is also shifted upwards (DE-A 2706 141).
  • a folding sword cannot guarantee the required stability because the lateral center of gravity cannot be shifted far enough to the rear and also moves upwards. The result of this is that the surfing device lurches in strong winds and high speeds, which leads to falls.
  • efforts are made to choose the shape so that the hull forms the smallest possible wetted area very quickly and easily at higher speeds, i.e. rises out of the water very quickly. This possibility of shaping, however, is limited by the known sword arrangements.
  • Another disadvantage is that the folding sword can not be placed vertically.
  • the shift of the lateral center of gravity is not long enough, so that the surfing device not only lurches in strong winds, but also becomes very lucrative.
  • a fin arrangement for a surfboard which consists of a longitudinal slot in the rear and in the underside of the surfboard and a fin arranged displaceably in the longitudinal direction therein.
  • the displaceability in the longitudinal direction is ensured by toothed ridges arranged in the slot side walls and corresponding pins.
  • the known device is not suitable for a plug-in sword arrangement because it is not accessible from the top of the board and also does not permit a folding sword arrangement.
  • the object of the invention is to provide a plug-in sword arrangement for a standing sail device which enables an optimal lateral point adjustment of the plug-in sword, in particular for high speeds.
  • a folding sword known per se, which can be actuated with the foot, is preferably used as the plug-in sword. Thanks to the new plug-in sword arrangement, optimal trimming positions of the plug-in sword can be selected, whereby the lateral center of gravity of the sword can be shifted both in the horizontal and in the vertical direction. In combination with several mast tracks, the new guarantees Plug-in sword arrangement almost all trim positions between the center of gravity of the sail and the lateral center of gravity of the hull, which are necessary for the optimal control of the standing sail device.
  • a telescopic sword is guided in the sword case, which can be pushed together and is also tiltably mounted in the sword case.
  • the plug-in sword arrangement according to the invention is accommodated in a hull 1 of a standing sail device. Only the mast foot 2, which sits in the mast track 3, is indicated from the rig of the standing sail device. Further mast tracks 3 can of course be provided in the hull 1, so that mast displacement in the longitudinal direction of the hull is possible.
  • the plug-in sword arrangement consists of the sword box 4 and the plug-in sword 5.
  • the plug-in sword is shown as a folding sword and, in a manner known per se, has the swivel and plug-in axis 6 arranged transversely to the plane of the sword surface with the two stub axles 7, 8.
  • Bre, ns, 3 pots 9 are arranged on both sides of the sword surfaces above the plug-in axis 6 and are intended to produce a frictional connection with the side walls of the sword case in a manner known per se.
  • Three cusps 10 are preferably formed on the sword head, which serve for the foot adjustment of the tilting position of the folding sword. In Fig. And 3, the possibility of tilting is indicated by the bow arrow. Folding swords of the type shown are known and are therefore not an immediate subject of the invention.
  • the new plug-in sword arrangement can also be equipped with other types of swords and types of sword, provided that a plug-in axle 6 with stub axles 7, 8 and preferably at least one brake plug or similar device generating friction is provided.
  • the length L is longer than the sword width B (Fig. 3). It is preferably longer than twice the width of the sword B. This measure makes it possible to move the sword in the sword case in the longitudinal direction of the hull.
  • the sword case 4 consists of the two side walls 11, 12 and the front wall 13 and the rear wall 14.
  • the design and shape of the front and rear walls of the sword case depend in a manner known per se on the shape of the edge of the sword. It is therefore not discussed in more detail in the context of the present invention.
  • the sword box forms the slot 15 with the upper slot opening 16 and the lower slot opening 17.
  • a friction lining is expediently provided on the inside, which cooperates with the brake plug 9 in such a way that the respectively set position of the sword 5 in the sword box 4 is preserved when sailing.
  • pimples 18 or similar locking means for brake plugs or the like can be arranged on the inner surfaces of the side walls 11, 12, which lock the respective position of the gradual pivoting and / or displacement of the plug-in sword.
  • the longitudinal displacement of the sword 5 in the sword box 4 is ensured by longitudinal grooves 19, 20.
  • the grooves 19, 20 are spatially opposite each other in the sword case 4 and run in the longitudinal direction of the hull.
  • the height of each groove is preferably only slightly larger than the height or diameter of the stub axles 7, 8, so that the stub axles can be guided in the longitudinal direction in the grooves.
  • the depth of the grooves corresponds to the length of the stub axles 7, 8, so that the displacement of the plug-in sword is not hindered.
  • the longitudinal grooves 19, 20 are each connected to a plug-in groove 21, 22, the grooves 20, 21 and 19 and 22 merge into one another, and the plug-in grooves 21, 22 have approximately the same dimensions as the longitudinal grooves 19, 20.
  • the plug-in grooves 21, 22 run vertically downward from the slot opening 16 until they meet the longitudinal grooves 19, 20 at right angles.
  • a different angle of incidence can also be selected, ie, for example, the longitudinal grooves can have an inclination to the horizontal and / or the plug-in grooves can have an inclination to the vertical (not shown).
  • the plug-in grooves 21, 22 are expediently arranged behind the longitudinal grooves 19, 20 (not shown), the front wall 13 being so far away from the foremost locking means 24 that the head of the folding sword can be pivoted forward unhindered and the function of the folding sword when opening Eg on the beach is not hindered.
  • slots 21, 22 can also be advantageous to insert the slots 21, 22 in the middle or to be provided at the end or at any other point of the sword box.
  • more than one pair of slots 21, 22 can be accommodated in the side walls 11, 12 of the sword case 4 (not shown).
  • the lateral center of gravity of the sword can be easily shifted upwards. If a telescopic retractable sword is also used as the sword, the lateral point adjustment is particularly possible.
  • locking recesses 24 can be arranged in the bottom wall 23 of each longitudinal groove 19, 20, into which the stub axles 7, 8 can be inserted. In this way, the selected position of the plug sword is determined. To move the sword 5 is only pulled up a little until the stub axles 7, 8 come under the top wall 25 of the longitudinal grooves 19, 20. Then the sword is pushed forward or backward in the longitudinal grooves.
  • a sword 26 or the like, which is known per se, is preferably used to actuate the sword 5, which is only indicated in FIGS. 1 and 3 and is not shown in the other figures, in order not to disturb the clarity of the drawing.
  • the shape of the locking recesses 24 is preferably based on the shape of the stub axles 7, 8.
  • the locking recesses are cup-shaped, so that they serve as rotary bearings for the round axle journals 7, 8. If, however, tilting or swiveling of the sword 5 in the sword case 4 is to be prevented, square stub axles and recesses can be selected, for example, so that the respectively selected position of the sword is locked. In this case, the friction linings or knobs 18 and the brake plugs 9 could possibly be omitted.
  • the lower slot opening 17 is closed with preferably two elastic, opposite and overlapping sealing lips 27 arranged on the sword case, for example made of rubber or plastic.
  • the sword 5 is inserted through the sealing lips 27, the lips being so elastic but also so firm that they nestle against the sword on the one hand and on the other hand in the areas which only cover the opening 17, prevent water from sailing splashed up out of the sword box.
  • the invention includes a considerable improvement in the maneuverability and trimming possibility of a standing sail device. Above all, it also makes it possible to optimize the hull shape in terms of sliding and climbing, which was previously pointless due to the lack of trim options.
