Definitions

  • a rig commonly used in windsurfing for a sailing board has become known, for example, from DE-PS 19 14 604.
  • This rig has a sail held open between a mast and a curved spar, the unstated one being free on all sides by means of a joint Rig can be rotated and swiveled on the sail board and held by the surfer on the spar and thus adjusted relative to the sail board and wind.
  • the typical sail shape for this is triangular, with the front end, namely the luff of the sail, being held on the mast.
  • the sail is connected to the spar provided in the form of a spreading tree and separated only by a rear cam.
  • the spar in the form of a spreader or boom is attached to the mast at its front end above the sail neck, so that the sail extending obliquely downwards from the rear cam to the mast is loosely guided between the outwardly curved booms.
  • Riggs with a sail area which have reinforcing ribs in the area of the upper leech of the sail, in order thereby to enlarge the active sail area somewhat.
  • a significantly better use of wind cannot be achieved by this.
  • the present invention creates a completely new type of rig for a sail board, which can be used to sail at a speed significantly higher than in the prior art, both in a weak breeze and in high winds.
  • This is made possible according to the invention by using a Y-shaped mast and a three-part sail attached to it.
  • the sail area is significantly increased in that two upper sail parts are provided at a distance from each other.
  • the wind forces can be utilized considerably better, since the wind that is incident obliquely to the sail area also acts on the sail area located at the rear and thus contributes to increased propulsion. Only in the sail position, in which "with the wind" is being sailed, is the rear sail in the slipstream, so that essentially no increased use of wind is possible.
  • the mast section of the fork mast arranged on the leeward side is raised further, so that this increases the effective sail area and in turn increases the propulsive forces. Since in this sailing position the windward diverging mast section with the partial sail attached to it is further lowered, this lifting position above all increases the buoyancy forces, which leads to less wetting of the surfboard and thus to an increased speed. Due to the buoyancy forces induced on the surfboard, the surf can jump over waves with his sailboard and fly for a short time.
  • the masts i.e. the boom and the sails or partial sails themselves are made smaller.
  • the center of gravity of the rig is lowered, i.e. it is shifted further towards the surfboard, which significantly increases the handling of the surfboard and rig compared to the prior art.
  • the risk of breakage is also reduced, and the weight of the entire arrangement is also reduced, particularly due to the smaller, stiff masts and the possible shorter booms.
  • the smaller design also has the further advantage that the sails can no longer blow out so far on the leeward side.
  • the spar in the form of the two booms at its end facing away from the mast runs vertically to the level of the booms in a dovetail shape in a double end and the sail is attached to the two ends of the spars.
  • This also makes a not inconsiderable increase in the sail area possible, which increases the propulsive forces.
  • the rigid and immovable fastening of the sail to the two ends of the spar in the form of a fixed two-point suspension facing away from the mast ensures that, above all, the upper leek cannot blow out too strongly due to the wind forces.
  • a sail rod is provided which is supported on the front of the mast, for example in the region of the mast fork on the holding member provided there for the individual mast sections.
  • This sail rod runs immediately above the seam at which the lower one-piece sail section merges into the two upper sail sections, the sail on the sail rod being trimmable at the end opposite the mast. This avoids, on the one hand, that the sails can blow as far as in the prior art, even in strong wind.
  • the spar in the form of the fork arrangement not to be formed in rigid fork trees, but instead to consist of a partially elastic or even completely elastic handle guide which, for example, hangs freely in the form of a rope.
  • This grip guide is attached and trimmed on the one hand at the front of the mast, also preferably at the level of the fork and on the other hand at the rear end of the sail rod.
  • the sail is thus braced only on the luff on the mast and at the rear end of the sail in the form of a one-point or two-point bracing on the sail rod.
  • a rig 1 is shown on a sailing board 3.
  • the rig 1 comprises a mast or fork mast 5, which is divided into a lower one-piece mast section 7 and two upper, mutually divergent mast sections 9.
  • the sail consists of a double or trisail 11, which is divided into a lower sail section 11a, and two adjacent sail sections 11b and 11c. Both the lower sail section 11a and the two upper V-shaped sail sections 11b and 11c are attached along their luff, for example via a mast hem to the mast 5.
  • the spar in the form of a fork arrangement 13 is fastened in its front end to the mast 5 in a known manner by means of pods.
  • the sail 11 is also fastened by means of pods.
  • the transition from the lower sail section 11a to the two upper sail sections 11b and 11c takes place along a seam 17 which runs at the height of the spar.
  • the spar itself is attached to the mast 5 at the usual height. In the area of the attachment point there is the transition from the lower one-piece mast section 7 to the two upper diverging mast sections 9.
  • the rigging attached to the sail board can be pivoted by means of a joint which is provided on the mast base and is not shown in more detail the spar serving as handles can be adjusted.
  • a holding member which the two upper Mast sections 9 holds in a rigid but adjustable angle As is indicated only schematically in FIG. 1 and what will be discussed later, when the transition from the lower one-piece mast section 7 to the two upper diverging mast sections 9 is provided, a holding member which the two upper Mast sections 9 holds in a rigid but adjustable angle. Furthermore, the mast 5 can also be made height-adjustable overall.
  • Figure 2a illustrates a basic position it represents by the bottom mast section 9 is substantially vertical to the water surface, the two upper divergent mast sections 9, for example an angle of 60 ° to 100 °, preferably 90 include 0th
  • the double formation of the sail creates a considerably larger sail area in the upper area, whereby in all sail positions where the wind falls at an angle to the sail, the wind pressure also acts on the leeward sail and thereby the propulsive forces increase.
  • FIGS. 2b and 2c schematically show the position of the sail when the wind is strong. From this it becomes clear that even with the strongest wind, the erection of the leeward sail now enables very large propulsive forces despite this extreme position, since the upper leeward sail section 11b is now practically complete is erected, and thereby offers the largest surface for the wind. Due to the windward lying sail section 11c, which in this extreme position is pushed further and further down to the water surface, enormously large buoyancy forces are introduced by the wind onto the rig 1 and thus the sailboard 3, so that this rig according to the invention provides the greatest possible propulsion forces and also buoyancy forces like a kite. As a result, the wetted area becomes smaller, the speed increases and, above all, wave jumps can also be made possible.
  • FIG 3 an alternative rig according to the invention is shown schematically in side view with a single sail.
  • the spar 13 with the two booms is not simply closed .
  • Oval but formed with two outlet ends 21 running apart in a dovetail shape.
  • the sail area can also be increased significantly in the case of a single sail, since the upper luff 23 of the sail rises towards the upper outlet end 21a and the lower luff 25 can extend recessedly towards the lower outlet end 21b, the sail being cut off at the rear between the two outlet ends and essentially parallel runs to the lower front mast section 7.
  • FIG. 4 shows a further development which combines the advantages according to FIGS. 1 and 3, thus has a fork mast and three sail sections 11a to 11c, the seam 17 running from the front attachment point of the spars on the mast 5 to the rear upper outlet end 21a of the spars 13.
  • the splitting into the two outlet ends does not have to be symmetrical to the plane of the two booms 13a and 13b, but can also be such that the lower outlet end 21b lies in the plane of the booms 13a and 13b and only the upper outlet end 21a runs out above this level.
  • Fig. 5 the holding member 19 for holding and carrying the 3 mast sections 7 and 9 is shown schematically.
  • the two mutually diverging mast sections 9 are guided through seam seams 27 on the upper sail sections 11b and 11c and secured on the holding member 19.
  • the lower mast section 7 is also inserted through a corresponding hem seam 27 and secured to the holding member.
  • the sail is then braced via sheets at the rear or at the rear outlet ends 21a and 21b.
  • the design of the holding member 19 can in particular be such that the angle between the two upper mast sections and the height of the entire Mast is designed to be adjustable.
  • the use of the sailing board is carried out in the same way as in the case of the well-known and initially mentioned rig according to the prior art.
  • the uprighting of the sail also takes place via a known starting sheet attached to the fork point.
  • the mast can also be V-shaped, the two sails 11b and 11c reaching down to their lower leech without the common sail section 11a. Since the sails are only a short distance apart in this lower area, the wind yield is not significantly increased.
  • the three mast sections are in one plane apart from their inherent curvature. It is also possible, however, that the upper diverging mast sections additionally run obliquely backwards away from the lower mast section, so that the upper sail sections 11b and 11c are formed like a kite in plan view.
  • FIG. 6 a further embodiment of the rig according to FIG. 6 is discussed, in which a rig is shown in a slightly rotated side view with the lower one-piece sail section 11a and the two upper double sail sections 11b and 11c.
  • a sail rod 31 is provided which, as only indicated, is supported on the front fork point 18 of the mast 5, i.e. can be fixed there or, for example, by means of a joint.
  • the sail can be trimmed tightly by means of a sail eye with its tapered end.
  • the sail rod 31 runs directly above the seam 17 between the two diverging sail halves 11b and 11c.
  • this arrangement ensures that the sails cannot blow out as strongly as conventionally.
  • the sail is held at its rear end only over the sail rod 31. But it is also possible that a sail hem is provided through which the sail rod can be inserted.
  • the spar 13 can be shaped with the fork arrangement in the form of a partially elastic or fully elastic, freely vibratable handle guide 33, which is only attached to the front of the mast, preferably in the region of the fork point 18 and at the rear end of the sail rod 35, for example by pods.
  • This handle guide is therefore not designed in the form of two outwardly curved large trees, but in this case can hang freely between the two suspension points on both sides of the sail surface 11a.
  • the handle guide 33 is, for example, at least partially elastic, it can essentially have a U-shape, the open one
  • the end of this grip guide 33 can be provided, for example, with two semicircular suspension bends 39 in order to mount this grip guide 33 at the fork point 18 from the outside around the mast sections 9.
  • the handle guide can then be fastened, for example by means of pods, to the rear end of the sail rod 35, which in particular also ensures a simple possibility for assembling and dismantling the rig.
  • the sail rod 31 can be releasably attached to the mast 5 or the holding member 19. However, it is also possible to fasten it via a joint mentioned, so that the sail rod can be folded with the mast in a space-saving manner when dismantling.
