Definitions

  • the invention relates to a sail board with a fastening arrangement for fastening a fin.
  • sailing boards have been developed in which the fins are pushed through and clamped from the top - similar to the sword of the sailing board - through a corresponding slot. Then for transport the fin can be released from the clamp and removed.
  • This type of fin attachment in turn has the disadvantage that a slot penetrating the sail board has to be made, which makes the manufacturing process for such a board more complex. In particular, a good seal must be provided in the area of these slots.
  • the object of the invention is accordingly to provide a sail board with an Eefesti supply arrangement for a fin, which allows the fin to be inserted or removed in a few simple steps and which can be attached without great effort in the manufacture of the sail board.
  • this sail board provided with the fastening arrangement should be suitable for being produced in the hollow body blowing process.
  • the advantage achieved by the invention is that the manufacturing process is considerably simplified and thus made more cost-effective.
  • the manufacturing process is considerably simplified and thus made more cost-effective.
  • only core grooves corresponding to the groove shape need to be attached, around which the plastic also applies during the blow molding process, thereby providing the sail board with an eirier groove at the appropriate point.
  • the fin has a profile piece on its upper side, the cross section of which is adapted to the cross-sectional shape of the groove. The fin is simply pushed from the open end of the groove.
  • a preferred embodiment of the invention provides for a recess on the groove base or in the groove walls, in which a correspondingly shaped resilient part of the profile piece, for example a tongue, engages.
  • a correspondingly shaped resilient part of the profile piece for example a tongue
  • this tongue engages in the recess.
  • the tongue is released from the recess with a finger or a pen and the fin can be pulled out.
  • a slot or a bore is made near the open end of the undercut groove, through which e.g. presses the spring tongue of the professional with the index finger 1 piece and can thus loosen the fin.
  • the profile piece of the fin On the closed end of the groove, seen in the longitudinal direction, it is tapered in a wedge shape; the profile piece of the fin has an arcuate curve at the corresponding end.
  • This design of groove and fin ensures a firm fit of the fin.
  • the curved part of the profile piece abuts in the wedge-shaped tapered part against the groove walls and is deformed a little bit elastically by the force applied when inserting the fin.
  • the restoring forces caused by this deformation in turn have the effect that the spring tongue is pressed into the recess and is held firmly there. Overall, this measure will achieve that the groove cannot wobble in the longitudinal direction of the groove.
  • the profile piece is provided with slits or incisions in the area of the curved curve. This ensures that resilient tongues are created which push the fin backwards when inserted.
  • the bottom of the groove is advanced more than the groove webs.
  • the profile piece of the fin has an appropriately designed nose. This nose takes up tipping forces. that act on the fin, for example, when touching the ground, and prevents the groove webs from being loaded with these tilting forces.
  • the profile piece and the actual fin-like part of the fin are detachably connected to one another.
  • the profile piece thus represents an "adapter" which is suitable for receiving various types of fins that are commercially available.
  • the profile piece designed as an adapter can also be designed such that the fin used in each case can be fastened at different positions when viewed in the longitudinal direction. This enables the user of such a sailing board to position the fin according to his individual needs.
  • Figure 1 is a side view of a fin with attached profile piece. 2 shows a section through a groove of a sail board with the fastening device according to the invention;
  • Figure 4 shows another embodiment of a Prof i 1 piece for the fastening device.
  • Fig. 5 shows a section through a groove and a fin inserted therein.
  • the sections I-I according to FIG. 3 and II-II according to FIG. 2 correspond to this section.
  • FIG. 1 shows a fin 1 with an attached profile piece 7, which is inserted into the groove 4 shown in longitudinal section in FIG. 2.
  • the profile piece has at its front end a nose 17 which engages in a corresponding Schuschnei fertilizer 19 of the groove 4 in the inserted state of the fin.
  • At the rear end of the profile piece there is a resilient tongue 14 on which a wedge 20 is placed. This wedge 20 engages in the inserted state of the fin in a corresponding recess 13 on the groove base 11 of the groove (see. Fig. 2).
  • the cross section of the profile piece 7 with attached fin 22 is shown in Fig. 3.
  • the profile piece is T-shaped. Elongated holes 18 are present in the web 21.
  • the flange 23 is cut at its rear end so that there is a gap 24 between the tongue 14 and the web 21.
  • the open end of the groove 4 closes with the rear edge of the Sailing boards 2 off.
  • slots 15 or bores which run vertically in each groove are provided on this rear end of the sail board. The user can press through these slots with his finger on the tongue 14 and thereby release the wedge 20 of the tongue from the recess 13 of the groove base 11.
  • the fin 3 is. the web 21 of the professional 1 piece in the area in which it merges into the fin 22. beveled.
  • the groove has corresponding bevels on the groove webs 12.
  • the fin 22 is curved outwards at its upper end and widened, so that in the inserted state of the fin it continues into the underside 3 of the sailing board in continuation of the curvature.
  • FIG. 5 shows a horizontal section through a groove 4 into which a fin with the flange 23 of the profile piece 7 is inserted.
  • the groove 4 tapers in a wedge shape.
  • the nose 17 abuts the wedge-shaped groove walls 24. Due to the deformation of the nose 17 and the restoring force caused thereby, the wedge 20 is pressed firmly against the edge of the recess 13 in the groove base.
  • the profile piece is provided by cutting slots 26 with resilient tongues 27, which force a reset 1. 5, the slot 15 for actuating the tongue 14 is also indicated.
  • FIG. 4 schematically shows a further embodiment of a profile piece 7, which serves as an adapter.
  • a profile piece 7 is inserted into the groove 4 and with a corresponding spring tongue 14 locked.
  • the profile piece 7 has a slot 25 downwards, into which commercially available fins can be inserted and fastened.

Abstract

L'aileron (1) d'une planche a voile doit pouvoir etre fixe et enleve avec peu de manipulations. Le dispositif de fixation necessaire a cet effet doit pouvoir etre monte sur la planche, lors de sa fabrication, sans trop de frais. A cet effet, dans la partie inferieure (3) de la planche est formee une rainure profilee (4) ouverte a une extremite. Sur la partie superieure de l'aileron (1) est montee une piece profilee (7) dont la section transversale correspond a la section transversale de la rainure (4).
