Definitions

  • the invention relates to a device for windsurfing devices for adjusting the distance between the boom and the surfboard, which has a drill which can be connected to the mast of the device and has axially spaced-apart depressions and a bolt which engages in the depressions for axial adjustment and determination of the aforementioned distance .
  • a known device of this type for adjusting the distance between the boom and the surfboard is connected on the one hand to the mast base of the surfboard and on the other hand to the mast.
  • the latch is located on the mast base.
  • the object of the invention is to provide a device of the type mentioned in the introduction, which enables a so-called water start in particular to be carried out more easily. Furthermore, a height adjustment of the boom should at least be possible when the surfer is standing on the floating surfing device.
  • a second tube is slidably mounted on the first tube and that the bolt is part of a locking device arranged on the second tube and can be unlocked by means of an element that can be operated while surfing.
  • the distance between the boom and the surfboard can be easily changed and readjusted at any time.
  • the distance in question is matched to the respective surfer by raising and locking the outer tube of the two telescopic tubes, which is directly or indirectly connected to the boom.
  • the distance mentioned can now be reduced by unlocking the locking device, for. B. by a pull line or a lever, and by pushing back the outer tube including the rig with the sail or the boom, optionally supported by a retractor, in the starting position, that is, in the position of the shortest distance, with subsequent relocking of the two telescopic tubes .
  • This minimum distance is such that the surfer lying in the water, with his feet supported on the surfboard by grasping the boom, can lift the rig with the sail sufficiently far out of the water so that the wind can reach safely under the sail .
  • the device is unlocked again and the rig or boom is set to the desired height and locked again, which is also easy to carry out.
  • the distance in question can also be conveniently set during the actual surfing in order to best suit the prevailing conditions.
  • Another advantage of the new device is that the rig with the sail is easier to lift out of the water even when the surfer is standing on the floating board. The device is then also unlocked to reduce the distance in question, so that the rig with the sail using the usual catch sheet due to the larger catch angle the sheet is lighter, that is to say with less force, from which water can be pulled.
  • a locking arrangement for locking the mast at the mast base can be designed such that the bolt automatically engages and / or can be adjusted via a lever arrangement or via a control element leading into the vicinity of the boom, whereby the height adjustment is further facilitated while driving.
  • markings can, for example, reflect the distance in cm from the bottom of the mast, but symbols can also be used.
  • the device according to the invention can also be retrofitted, at least in the case of those mast feet which enable the mast shoe to be fixed at at least one height, for example commercially available mast feet with circumferential transverse grooves.
  • the windsurfing device shown in Fig. 1 consists of the usual surfboard 1, the rig 2, which is composed of a mast 3 and a boom 4 and is provided with a sail 5 and the proposed device 6, which in the example shown on the one hand with the Mast foot joint 7 of the surfboard 1 and on the other hand is connected to the mast 3.
  • the device 6 is pulled apart by the dimension a and locked in this position, so that the boom 4 to the surfboard 1 has such a distance that is generally perceived by the surfing person as useful.
  • the device 6 is shown in detail, it consists of an inner tube 8, an outer tube 9 and a locking device 10, the z. B. is attached by means of screws 11 below the outer tube.
  • the lower end of the inner tube 8 is, for. B. at 12 by means of screws with a socket 13, which in turn is advantageously rotatably mounted in the mast foot joint 7 of the surfboard 1.
  • the socket 13 is detachably connected to the joint 7, so that the device 6 can be separated from the surfboard, for example for transport purposes.
  • the two tubes 8 and 9 can be moved telescopically one inside the other and can be adjusted in the desired position in the axial direction and can be locked by means of the latching device 10.
  • the latching device 10 consists of a housing 14 with a latching bolt 15 and with a spring 16 (FIG. 3), which presses the bolt 15 normally into the locking position, for which purpose the bolt has a contact shoulder 16a.
  • the locking device comprises locking recesses 17, which are provided on the outer surface of the inner tube 8, in the direction of the axial extension of the inner tube 8.
  • the inner tube is provided with an axially extending longitudinal groove 18, the bottom of which is provided with the locking recesses 17 spaced apart from one another is, the locking recesses advantageously consist of holes.
  • a guide element 19 is also provided, for. B. in the form of a bracket.
  • a pull cord 20 runs as an operating element, which is connected on the one hand to the outer end of the locking bolt 15 and on the other hand can be detachably attached to the mast 3, advantageously in the region of the point at which the boom 4 is also attached to the mast 3.
  • the bracket 19 ensures a safe retraction of the locking pin 15 when the surfer Rope gripped at its upper end and pulls on it.
  • a retraction device 21 is provided for this purpose.
  • e.g. B. can consist of a rubber strand.
  • This rubber strand is fixed on the one hand on the outer tube 9 and on the other hand on the inner tube 8 in a conventional manner. Since the two pipes 8 and 9 are said to be relatively extensible, e.g. B. by a dimension of 40 to 60 cm, and are accordingly long, the rubber cord 21 must have a corresponding deflection distance.
  • the inner tube 8 is provided in the region of its lower end with an inner, conventional deflection block 22 which, for. B. is fixed by means of a bolt 24 so that the strand is guided around this block and fixed at the upper end of the inner tube 9.
  • the strand 21 has a sufficiently large basic length that allows the tubes 8 and 9 to be pulled apart relatively far.
  • the lower end of the outer tube 9 is also provided with a slip eyelet 25, which serves to ensure that the sail 5 can be fixed to the device 6, as illustrated in FIG. 1.
  • a slip eyelet 25 which serves to ensure that the sail 5 can be fixed to the device 6, as illustrated in FIG. 1.
  • the sail 5 is pulled over the mast 3 and the mast is in turn pushed over the outer tube 9 to the stop on either the housing 14 or the eyelet 25, it is ensured that the rig 2 with the sail 5 does not inadvertently can solve from the device 6.
  • the device 6 is arranged between the mast ankle 7 of the surfboard 1 and the foot of the mast 3.
