Definitions

  • the invention relates to a standing sail device (windsurfer) with a surfboard and a sail, which can be freely rotated and pivoted on all sides by means of a universal joint on the surfboard and is controlled by the user with the aid of at least one handle bar (handle spar).
  • Such standing sail devices are known in principle and are very popular.
  • the disadvantage is that it is relatively difficult to sail against the wind direction or gain height.
  • the invention is therefore based on the object of improving the driving properties of the standing sail device in such a way that it can be driven with less effort against the wind and, above all, also higher in the wind than the known standing sail devices.
  • the invention provides that the sail surface is symmetrical with respect to its vertical axis and has, from above, curved sail edges (beds) which run away from one another in an arc, to which sail edges (beds) which run towards one another towards the universal joint or sail neck connect that Furthermore, the sail is held by a peripheral frame and that the handle bar (handle spar) with its two free ends is rotatably or pivotally attached to the peripheral frame.
  • peripheral frame runs along the entire contour of the sail, so that it is held on all sides by frame parts (frame spars) and can therefore be stretched extremely taut. Together with the inventive sail shape or sail surface is obtained in the possibility l ichkeit very close to the wind or against the wind surf.
  • At least one adjustable spacer that changes the distance between the frame parts (frame spars) is also provided, whereby a change in the profile of the sail can be achieved.
  • the sail can therefore be optimally adjusted (profiled) at any time.
  • the sail 5 is held by a peripheral frame 6 which extends along the outer contour of the sail 5.
  • the sail 5 is attached to the peripheral frame 6, for example, with the aid of sail bags.
  • At least one handle bar 8 (handle spar) is also provided on at least one side of the sail 5 for holding by the user, but handle bars 8 and 9 are preferably arranged on both sides of the sail 5 and expediently rigidly connected to one another.
  • the self-contained circumferential frame 6 consists of a plurality of elongated, rod-shaped frame parts (frame spars) 10, 11, 12 and 13 which, in the exemplary embodiment according to FIG a triangle or a trapezoid (see dash-dotted line in Figure 3) to the universal joint 7 and arch upward.
  • the sail 5 is preferably provided with a tip 14. Relative to a central vertical axis 15 leading through the universal joint and the tip 14, the sail 5 or the sail surface and the peripheral frame 6 are designed symmetrically. Furthermore, the two frame parts 10 and 12 located to the left of the vertical axis 15 in FIG.
  • the frame parts 10 and 11 are preferably rectilinear, but they can also be slightly concave or convex (not shown).
  • a mast is not provided.
  • the frame parts or preferably the two upper frame parts 12 and 13 according to FIG. 1 run parallel to one another over a certain height H (parallelism not shown in FIGS. 1 and 3) and each have a plurality of fastening points at the same distance from one another 18 for the handlebars 8 and 9, so that they can be attached to the peripheral frame 6 optionally at different heights.
  • the fastening points 18 are, for example, bores in the frame parts and also serve to fasten at least one spacer 19 that can be changed in length. This spacer 19 ensures that the spacing of the frame parts or the mutually opposite fastening points 18 on the peripheral frame 6 can be changed is what changes the profile of the sail is achieved.
  • the spacer 19 consists of a rod 20 with opposing threads 21 on its free ends 22 and 23 and two head pieces 24, 25 arranged on the free ends 22, 23. These head pieces 24, 25 each have one cylindrical part 26 with an internal thread 27 such that the two head pieces 24, 25 either move away from one another or move toward one another when the rod 20 rotates about its longitudinal axis.
  • each head piece 24, 25 has a fork-shaped part 29, which consists of two tabs 30, 31 which grip around the frame part located in the area of the fastening point 18 of the peripheral frame 6 or accommodate it between them.
  • a bearing pin 32 passes through bores 33, 34 in the two brackets 30, 31 and the fastening point 18 designed as a bore in the peripheral frame 6.
  • the bearing pin 32 is secured by a nut or a split pin 35.
  • the axis 36 of the bearing bolt 32 and correspondingly the axes of the bearing bores 18 serving as fastening points in the peripheral frame 6 are perpendicular to the sail 5 or the sail surface. Furthermore, the axis 36 is perpendicular to the axis 37 of the rod 20 of the spacer 19, so that each head piece 24, 25 is pivotally held in the plane of the sail 5 or parallel to this plane on the peripheral frame 6.
  • the spacer 19 can serve directly as a handle bar.
  • the two Handle bars 8 and 9 are then not required.
  • the attachment and pivotable mounting of the handlebars 8, 9 takes place in the illustrated embodiment directly on the spacer 19 or on the rod 20 or outside on the cylindrical parts 26 of the two head pieces 24, 25.
  • the handlebars 8, 9 on their Ends of bearing parts 38, 39, each with a bearing bore 40.
  • each head piece 24, 25 passes through the bearing bore 40, so that the handle bars 8, 9 are not only freely pivotable about the axis 37 of the spacer 9, but the parts are also displaceable in the longitudinal direction relative to one another.
  • the handle bar 9 is only shown in dashed lines because the use of a single handle bar 8 is generally sufficient.
  • the handle bar 8 and the spacer 19 to be rotated in order to perform its function are then constantly on one side of the sail 5 indicated by dash-dotted lines in FIG. 2.
  • handle bars 8 and 9 are used on both sides of a sail, the ends 41, 42 of the handle bars 9 are also connected to the bearing parts 38, 39.
  • the sail 5 according to Figure 1 is preferably in one piece.
  • the lower part of the sail area consists of a triangular sail area 43 standing on the top and an upper sail area 44 with sail edges (beds) which run in an arc shape corresponding to the frame parts 12, 13.
  • the embodiment shown in Figure 3 differs from the embodiment according to Figure 1 in that the sail is in two parts and consists of an approximately triangular bottom sail 47 and an upper sail 48 arranged at a distance above it. In this way, for example, a wide, horizontally lying viewing gap or a window 49 can be created at the user's head height, which allows an unobstructed view.
  • a tensioning element 50 preferably in the form of at least one traction rope, by means of which it is possible for the sail edges 51, 52 (lying) lying opposite one another to run at right angles to the vertical axis 15 of the peripheral frame 6 of lower sail 47 and upper sail 48 in the vertical direction in a more or less, arbitrarily strong position to hold.
  • the pull rope 50 is guided through eyelets (not shown in FIG. 3) and extends, for example, in a W-shape between the two sail edges 51, 52.
  • the peripheral frame 6 can be reinforced in particular in the area of the fastening points 18 for the handle bars 8, 9 by a sleeve 53 or a sleeve-shaped body 53 which also serves as a possible connecting element for the frame parts 10 and 12 or 11 and 13.
  • a holding part 54 connects the frame parts 12 and 13 in the area of the tip 14 and a connecting element 55 is provided in the area of the universal joint 7 in order to produce a secure fastening of the two frame parts 10 and 11 to the universal joint 7.
  • the holding part 54 and the connecting element 55 can be joints, so that the frame parts can be moved relative to one another about axes 56 and 57 which are perpendicular to the sail surface.
  • a stop 55 a on the cylindrical part 26 of the head pieces 24, 25 ensures that the rod 20 of the spacer 19 cannot be unscrewed from the head piece 24, 25.
  • the circumferential frame 6 is tubular in cross-section, but in principle it can also have a different profile.
  • the sail bags 58, 59 take up the frame parts with a lot of play. Their width B is 5 to 10 times the thickness of the frame parts. (The illustration in FIG. 1 is not to scale).
  • sail 5 or 47, 48 can be used both as a scratch sail and as a mainsail.
  • the position of the sword 3 and the universal joint 7 on the surfboard 2 is adapted to the symmetrical shape of the sail and to the main position of the user resulting from the shape of the sail.
  • a spacer can also consist of rod-shaped or sleeve-shaped parts which can be telescopically pushed together without the use of threads and locked in different lengths.
  • the invention is therefore not limited to the specifically illustrated and described exemplary embodiments.
