Definitions

  • the invention relates to a profile sail for a sailboat, consisting of a mast with several superposed, individually expandable or reefable sail trees on the mast, between which an outer sail covering bridging the maximum vertical distance is provided and the at least two each with a vertical hinge axis connected, together have a symmetrical wing profile corresponding horizontal tree parts, one of which encloses the mast.
  • the object of the invention is to simplify the pulling and reefing of the superimposed sail sections and thereby the mast length of the respective one Adjust sail size and provide an improved adjustability of the curvature of the profile sail in order to achieve an optimal curvature distribution over the width of the sail.
  • the length of the mast consisting of several telescopically guided tubes is adjustable, that the inner tube carries a fixed top piece of the sail approximated to an elliptical outline in side view, the between the top piece and the bottom sail tree fixed to the outer tube intermediate sail sections as well as the sail trees suspended from the mast, which can be lifted by mast extension or reefing devices attacking the movable sail trees, can be reefed while shortening the mast, and that for optimal distribution of curvature along the axis of the airfoil profile, which forms the front third of its length, is articulated connected tree parts of each sail tree can be adjusted jointly by an arch adjustment drive.
  • the heel ie the inclination of the mast and thus of the boat, which is mainly caused by wind forces acting on the upper end of the sail, can be kept small, so that the boat keel, which is otherwise required for stabilization, can be reduced or replaced by a small sword.
  • the semi-elliptical outline shape of the sail is preferred because it has significant aerodynamic advantages. Due to the chosen sail shape, The changeable sail height and the adjustable curvature distribution can be taken into account or suitably used by suitably trimming the sail, and favorable propulsive forces can be achieved with minimized heeling.
  • the profile sail comprises a mast 10 consisting of telescopically guided tubes, the outer tube 12 of which is supported with a lower region in the boat hull, not shown, by means of a rotary bearing, where a rotary adjustment drive acts on a lower pivot 14 of the outer tube 12.
  • the outer tube 12 Above its passage through the boat deck, the outer tube 12 is divided and provided with flanges 16, which have a common horizontal hinge axis, so that the mast can be folded down with a reefed sail into a tub arranged on or near the boat deck.
  • a central tube 18 is guided in the outer tube 12, and an inner tube 20 is guided therein, which remain in a sufficiently large overlap in the extended state for the purpose of kink stability.
  • the telescopic tubes 12, 18, 20 are guided into one another with low friction by inner guide rollers 22, 24, which are distributed at their upper end on their circumference, and by outer guide rollers 26, 28, which are arranged at the lower end of their outer periphery.
  • a winch 30 is provided for a tension member or tension band 31 below the mast, which via an outer deflection roller 32 arranged at the upper end of the outer tube 12 and via lower and upper deflection rollers 34 and 36 of the middle tube 18 to the lower end of the Inner tube 20 is guided.
  • a lock shown in FIG. 5 is provided at the upper end of the middle tube 18 in order to hold the middle tube on the outer tube so that the inner tube 20 is first actuated by the winch 30 when extending .
  • FIG. 1b, c corresponds to approximately half an ellipse, so that the shape of the upper end of the sail is determined by the small ellipse half-axis.
  • This end of the sail is formed by a top piece 40 fastened to the upper side of the inner tube 20, which remains above the telescoped mast tubes when the mast is retracted and the sail is reefed according to FIG. 1a.
  • An upper sail section 42 is suspended from the top piece 40 and is limited at the bottom by an upper sail tree 44 in its length and in its cross section corresponding to a symmetrical wing profile.
  • a central sail section 46 extends from upper sail tree 44 to a middle sail tree 48, and a lower sail section 50 extends from the middle sail tree 48 to a lower sail tree 52 fixed to the outer tube 12.
  • the sail trees 44, 48 are guided according to FIG. 2 on the outer tube 12, which, as the other tubes also have a polygonal, for example square, cross section. Since the upper sail boom 44 is inevitably supported on the center tube 18 when the sail is fully set as shown in FIG. 1c, this carries an adapter 54 which takes over the guiding and locking of the upper sail boom 44 until the sail is in the half or fully raised state Fig. 1b or 1a is transferred.
  • the sail trees consist of a lattice frame construction, preferably made of light metal or glass fiber reinforced plastic, and can be individually and collectively reefed by means of deflection rollers, cable pulls and winding motors arranged in the lower sail tree 52, not shown, in order to pull a sail section down over the next higher tree and reef the sail to that extent.
  • the cables of the reefing device run from the winches of the winding motors with braked freewheel.
  • the cables of the reefing device for the upper sail tree 44 are passed through the lower sail tree 48.
  • the lower sail tree 52 for example trough-shaped, attached to the outer tube 12 approximately at the level of the boat deck, takes the folded ones when the sail is reefed Sail sections with the overlying sail trees.
  • the adapter 54 fastened to the outside at the upper end of the center tube 18 according to FIG. 5 has outer guide surfaces 56 which continue the outline of the outer tube 12.
  • One or more pawl levers 58 are pivotally mounted on the adapter and are resiliently pretensioned with their lower pawl end 60 in the direction of an inner shoulder 62 of the outer tube 12, so that the center tube and the outer tube are automatically locked as soon as the center tube is completely retracted.
  • Each pawl lever 58 carries on its upper curved arm a bolt or roller 64 which, when the sail is pulled out of the state according to FIG. 1b in the one according to FIG.
  • a bolt 70 that is prestressed in the direction of the adapter is horizontally guided on the sail tree 44, which in the state of FIG. 5 in a receptacle 72 in the adapter about a horizontal axis 68 swiveling holding member 74 engages.
  • the holding member 74 can be resiliently biased into its lower end position shown, in which a stop inclined surface 76 protrudes from the adapter 54 at its lower end and is opposite a stop 78 on the upper side of the outer tube 12.
  • the holding member 74 When retracting the center tube 18, the holding member 74 is pivoted clockwise to the left by the stop 78 on the outer tube 12, so that the latch 70 is free from the support surface of the receptacle 72 and the locking of the sail tree 44 on the adapter is released.
  • the sail tree 44 can now be pulled down from the adapter onto the outer tube 12 by means of the reefing device, the ratchet lever 58 restoring the locking of the middle tube 18 to the outer tube 12 and the bolt 70 being pressed back into the sail tree by means of an inclined surface 79 on the outer tube.
  • each sail tree consists of a rear tree part 80 which surrounds the mast 10 with a guide and extends over approximately two thirds of the total length of the wing profile.
  • a middle tree part 84 which is delimited by slightly convex outer sides 86, is connected to this by means of a vertical hinge axis 82.
  • a front tree part 88 the outer sides 90 of which correspond to the profile at the front end of an airfoil, is articulated on the tree part 84 by means of a vertical hinge axis 92.
  • first lever 94 and a second lever 96 are mounted centrally, which in the exemplary embodiment shown extend approximately over half the length of the respective tree part and are connected to one another in an articulated manner by a coupling strap 98.
  • the levers are arranged within the respective sail tree and lie in the longitudinal axis of the sail tree when the sail is stretched.
  • rotatable front and rear pairs of rollers or sprockets 100, 102 are mounted in the same arrangement, each roller pair consisting of an upper and a lower roller and, for example, the upper roller above and the lower roller is arranged below the lever.
  • the reference numerals of the individual rollers are only entered for the rollers of the second lever 96.
  • the upper rollers 104, 108 of the first lever 94 are wrapped in opposite directions by an articulated tension member, preferably a chain 112, the rear end of the chain 112 on one side of the rear tree part 80 and the front end of this chain on the opposite side Side of the middle tree part 84 is attached at a lateral distance from the respective roller.
  • the lower rollers 106, 110 of the first lever 94 are wrapped by a chain 114 in a mirror-symmetrical arrangement to the upper chain 112.
  • the second lever 96 is one with its ends laterally on the middle Tree part 84 and upper chain 116 fastened to the front tree part 88 and a lower chain 118 fastened to the lower rollers 106, 110 in a mirror-symmetrical arrangement for this purpose, attached to the opposite sides of the lower tree part or front tree part.
  • the rear end of the first lever 94 is articulated at a point 122 to a swivel actuator 124, which in the example shown consists of a screw spindle 130, mounted transversely on the rear tree part 80 and driven by a motor 126 with reduction 128, on which one with the Lever end related nut 132 is guided.
  • the chain 112 guided over the upper rollers 104, 108 pulls the left outer side of the middle tree part 84 to the front end of this lever which is pivoted to the right so that the middle tree part 84 reaches, for example, the position shown in FIG. 4c.
  • the second lever 96 which is mounted on the hinge axis 92 at the front end of the central tree part 84, is pivoted in the same direction, with the front end of the chain 116 guided over the upper rollers 104, 108, the left outside of the front tree part 88 to the already pivoted lever, but with additional translation effect.
  • the respective sail tree with its individual tree parts is brought to an opposite curvature and the desired curvature distribution increasing on the wing profile is achieved.
  • the covering of the individual sections of the sail has a certain elasticity, with which any convex curvature of the sail or its covering can be adjusted by contacting the outside of the tree parts.
  • FIGS. 4b and 4c on the concave sail side where the covering also bears against the contours of the tree parts, the covering is held on the side edges of the tree sections by means of inner loops or eyelets, not shown.
