Definitions

  • the invention relates to a floating body, in particular a multihull boat with a sail drive.
  • the object of the invention is to increase the safety and the ease of use and ease of use when using such a float and to improve the driving properties, in particular also to increase the speed.
  • a floating body which is designed as a multi-hull boat with at least two hulls connected by at least one cross member, these individual hulls are pivotally connected to at least one cross member at least in the vertical planes extending through their longitudinal axis.
  • the subject matter of the invention is characterized in that the hulls and the cross member embody a closed system of forces.
  • the reaction forces resulting from the pounding movements of the hulls are only insignificantly transferred into the cross member, as a result of which results in a significant improvement in user convenience.
  • connection between the individual fuselage and the cross member can comprise at least one joint, preferably a joint with a joint axis that is essentially parallel to the cross member, so that the fuselage can pivot freely in a plane determined by its longitudinal extent.
  • springs counteracting the pivoting movement and / or shock absorbers damping the pivoting movements can be provided.
  • a membrane coupling arranged between the individual fuselage and the crossmember can also be used within the scope of the invention for the articulated connection of the fuselage to the crossmember.
  • Such a membrane coupling then consists of an inner hub part, e.g. an inner ring or frame, which is connected to a ring-shaped or frame-shaped outer part via a disk made of elastic material.
  • the aim of the present invention is to make the elasticity of the connection effected with this membrane coupling different in the different directions of deflection.
  • the outer part has dimensions that differ from one another or strengths and / or elasticities that differ from one another in two mutually transverse directions.
  • the diaphragm coupling can counteract the deflections of different magnitudes occurring in different planes
  • the membrane coupling according to the invention with its elasticity differing in different planes can be advantageous in many fields of application; In boat building, it provides the advantage, in part, that the unsprung masses of the boat are reduced and the travel comfort is improved in the application for connecting a single hull to a cross member. In addition, the heel is reduced and the risk of a "trip" of a multihull boat is eliminated. The boat hulls tend to pound considerably less. Numerous other features of such a membrane coupling will be explained in detail later with reference to the drawing.
  • hollow bodies filled with a fluid medium preferably connected to one another via a connecting line, can be assigned to these hulls within the scope of the invention.
  • the damping can be regulated by means of a throttle valve arranged in such a connecting line.
  • an energy converter that can be operated by the medium flowing through it, e.g. a turbine can be arranged to utilize the energy generated by the swings of the boat hulls.
  • float according to the invention which serve to solve the problem defined at the outset of separating the aerodynamically or hydrodynamically acting forces, relate to the rig consisting of mast, foresail and mainsail and shrouds.
  • this rig of the floating body formed as a multihull boat is only fixedly attached to the cross member.
  • the stay for the foresail can advantageously be pivoted about a location on the crossmember, preferably in the area of the mast base, e.g. be guided and held on an arc-shaped running rail which extends between the hulls.
  • a beam carrying the stage of the foresail is articulated on the cross member, preferably on the mast foot, and can be pivoted about a vertical axis.
  • This can Klüverbaum d 9 nn. representss variation of the image projected on the wind direction
  • the sail area can be moved by means of pods.
  • the jib boom is connected to the crossmember in a selectively fixable manner, in such a way that, at the free end of the jib boom, two rods or the like extending on both sides to the crossmember . are articulated with one of their ends and the other ends of these rods are movable by means of runners along guides arranged on the cross member.
  • the position of the sails in relation to the wind direction can be optimized and a greater propulsive force can be achieved.
  • the possibility is also opened up to make the operation of the boat as easy as possible, to improve the handling and to ensure compliance with and maintenance of a certain chosen course more easily and reliably
  • an extensive closed guide on the cross member e.g. provide a running rail on which both the runners of the rods articulated at the free end of the jib boom and the fetching points of the sheets of the sails are guided by means of such runners.
  • the runners can be connected to one another at a distance by means of a pulling element guided along the guide and for the purpose of adjusting the sails and their trees by means of the pulling element and a drive assigned to this pulling element, e.g. a roller or gear drive, movable along the guide.
  • a pulling element guided along the guide and for the purpose of adjusting the sails and their trees by means of the pulling element and a drive assigned to this pulling element, e.g. a roller or gear drive, movable along the guide.
  • the invention is also concerned with improving the stability of the floating body in the sense of the initially defined objective, namely that according to the invention in the case of such a floating body designed as a multihull boat, a sword running in the longitudinal axis of the boat on the underside of the crossmember into the water immersed attached.
  • the free-flowing sword thus absorbs large lateral forces immersed in the water and when the boat begins to heel, the risk of capsizing is considerably reduced, because at the same time the lateral area of the sword is reduced with the heeling, because the heel increasingly heaves the sword out of the water . As a result of the reduction of the lateral forces and the heeling moment, the boat can then easily return to its horizontal position.
  • the multihull boat shown in FIGS. 1 and 2 for example a so-called catamaran, consists of the cross member 1 and the two hulls 2, which are connected to the cross member 1 by means of joints 3 and are held in a desired position by means of the springs 4.
  • Shock absorbers 5 ensure damping of the swiveling movements of the fuselages 2 about the swiveling axis coaxial with the axes of the joints 3.
  • the hulls 2 can carry out movements independently of one another and from the cross member 1 and can adapt to the sea conditions individually. Pounding movements of the hulls 2 are only transmitted to a minimal extent to the cross member 1 and a cabin arranged on this cross member, which results in a considerable improvement in comfort when using the boat.
  • the mass of the parts of the boat to be lifted at sea becomes less and an undercut of the hull tip becomes more likely avoided than with a rigid connection between hulls and cross beams.
  • the mast 6, the shrouds 7 and other components of the rigging are only attached to the cross member 1 according to FIG. 2, so that no reactions originating from the wind forces are introduced into the hulls 2 and, on the other hand, the tamping movements of these hulls 2 can have no effect on the tensions in the shrouds 7 which keep the mast 6 in the desired position with the vertical axis 8.
  • the membrane couplings shown in the following figures can be used for the articulated, flexible connection of the hulls 2 to the cross member 1.
  • FIG. 3 shows such a coupling, arranged in each case between an individual fuselage 2 and the cross member 1, in a cross section, the parts to be connected to the fuselage and cross member being designated 1 'or 2'.
  • Each such coupling consists of a disc 9, which connects an annular or frame-shaped outer part 10 to an inner hub part 11 and in turn is made of elastic material, for. B. of metal, rubber, fiber-reinforced plastic or the like.
  • the edges of the disk 9 could be firmly connected to the outer part 10 or the hub part 11 in the areas 12 in any way, e.g. by clamping by means of screws, by gluing, welding, clamping and the like.
  • the coupling as a whole is designated by 13, its axis is designated by reference number 14.
  • FIG. 4 shows that the outer part can have dimensions that differ from one another in two mutually transverse directions.
  • the outer part 10 is elliptical and accordingly the disk 9 is larger in the direction of the main axis of the ellipse than in the direction of the secondary axis.
  • the outer part 10 and the hub part 11 of the coupling 13 consist of two concentric ellipses with their main axes parallel to one another, according to FIG. 8 the main axes of such ellipses are perpendicular to one another and according to the figure q the outer part consists of an approximately rectangular part and the hub part from a circular frame.
  • F i gur 10
  • approximately rectangular frames form the outer part 10 and the hub part 11.
  • a membrane coupling according to the invention is not only suitable for the special case explained above for use in a multihull boat, but also for all other areas of application in mechanical engineering.
  • this coupling is designed in such a way that a medium can flow through it in the direction of the arrow 16, which may be advantageous for various fields of application.
  • the disk 14 shows a variant of the disk 9 or the disk holder 12, according to which the disk 9 has a bead-shaped reinforcement 9 'on its inner and outer edge, which is held in a form-fitting manner in a correspondingly profiled groove in each of the parts 10 and 11.
  • the disk consists of two layers 9a and 9b, between which a fluid medium can be enclosed. This results in a change in the spring constant, e.g. due to the curvature of the disk caused by the pressure of the fluid medium.
  • the division of the disc into two layers also has other advantages with regard to deformability and - as shown in FIG.
  • a wedge-shaped insert 17 can be inserted between the two layers 9a and 9b in this way. That in the event of a load, the clamping pressure acting on the pane edges is increased and such self-clamping occurs and prevents the pane edge from sliding out.
  • the different reaction of the clutch in different levels can not be within the scope of the invention merely by different design and dimensioning of the parts holding the disk 9, the outer part 10 and the Hub part 11, achieve, but also by designing the disc 9 with locally and regionally different strengths and / or elasticities. This can be achieved by reinforcement or different dimensions of the thickness of the disc 9.
  • FIG. 16 shows a multihull boat, the cross member 1 of which is articulated to the hulls 2 by means of couplings 13 according to the invention.
  • the longitudinal axis B around which each fuselage 2 rolls, runs in the longer axis of the outer part 10 of each coupling 13.
  • the deflection ⁇ about this axis B is comparatively small.
  • the axis C can be seen in the plan view according to FIG. 17.
  • the reaction force of the coupling 13 should be large and counteract even small deflections of ⁇ extent. Even if waves hitting the side of the boat generate high torques, this angle T- should remain as small as possible.
  • the axis C therefore runs perpendicular to the plane determined by the disk 9 of each clutch 13.
  • the axis A can be seen, around which the hulls 2 stamp.
  • the high degree of freedom of the couplings 13 in this axis by the angle ⁇ is therefore appropriate in order to enable the hulls 2 to be largely adapted to the shafts independently of one another. This maintains a laminar inflow of the hulls for longer and increases the speed of the boat.
  • FIG. 19 and FIG. 20 show how the hulls 2 can be assigned a movement damping device which consists of hollow bodies 18 filled with a fluid medium, which according to FIG. 20 are also deformed by the deformations of the couplings 13.
  • the desired degree of damping is easily adjustable with such a device.
  • the hollow bodies 18 can thus be connected via a connecting line 19 in which a throttle valve 20 for regulating the flow is arranged, as shown in FIG. 20.
  • this connecting line 19 it could also be an energy converter that can be operated by the medium flowing through it, e.g. a turbine 21 may be arranged.
  • FIGS. 22 and 23 In the embodiment of a multihull boat shown in FIGS. 22 and 23, one of the numerous possibilities is illustrated for making the attachment of the headsail independent of the hulls and thereby achieving the aim of the invention defined at the outset.
  • the forestay 29 of the rig of this boat is attached to a jib boom 30 which is pivotally mounted on the mast foot 31 of the mast 6 about the vertical axis 8 of this mast and is braced by means of a water shroud 32 which in turn is on the same axis 8, namely on the underside of the cross member 1 is stored.
  • the jib boom is held in its respective target position by two pods 33 and can be adjusted to starboard, port and in any intermediate position as required.
  • an arched running rail 35 can also be provided, which extends between the two hulls 2 and on which the stay 29 for the headsail 36 is guided and held.
  • a runner 37 holding the forestay 29 can be moved on the arc-shaped running rail 35.
  • the forestay 29 can be pivoted about the axis 8 of the mast 6 attached to the cross member 1 by means of the running rail 35 and this runner 37.
  • the present invention is also concerned with various things Possibilities to make a swiveling jib boom as stable as possible and to bring and hold it reliably within the swiveling range in predetermined positions, which ensure that a certain course is maintained with optimal use of wind forces and currents.
  • the jib boom 30 shown in FIG. 25 is braced for the sake of strength and stability by means of two rods 38 with respect to the cross member 1 of the boat, namely two rods extending to the cross member 1 on both sides of the free end of the jib boom 38 articulated with one of their ends and the other ends of these rods 38 are movable by means of runners 39 along guides 40 arranged on the cross member 1, in such a way that these runners 39 join in the movement of the jib boom 30 when the jib boom 30 is pivoted and in each case in the desired target - Swivel position can be fixed to hold the jib boom 30.
  • one of the runners 39 can be used as a fetch point for the advance sheet of the foresail 36, advantageously because the required distance of this fetch point from a winch winch for the advance sheet can be ensured by guiding the fetch point through the guide rail 40 and also because the forces acting on the foresail 36 from the lay tensions do not have to be absorbed via the sheet but can be dissipated via the rigid rod 38.
  • the sheet of jib boom 30 and large boom 41 is guided over a roller 42.
  • the wind pressure force 45 gives a (negative) torque 48 about the pivot axis, ie about the axis 8 of the mast 6, while the wind pressure force 47 from the mainsail 34, on the other hand, gives a torque 49 turning right about this axis 8.
  • the sail surface 55 projected onto the wind direction 54 is only half as large as the sail surface 57 when the foresail 36 is pivoted out in the case of a jib boom 30 running in the boat's longitudinal axis 56.
  • Additional jib sails can be placed between the headsail 36 and the mainsail 34 to increase the jet effect, which leads to a significant increase in propulsion.
  • Figure 29 shows the situation similar to that of Figure 28, but for downwind courses. Here too there is a significant increase in the sail area 57 projected in the wind direction 54.
  • FIG. 31 the features of the invention shown in FIGS. 22 to 30 are again illustrated in their context.
  • the foresail 36 is shown in full in the "upwind position” and dashed in the "upwind position", the pivotable jib boom with 30 and the course of the sheet are shown in dashed lines.
  • the changes in the length of the jib correspond to the required bowiness of the sail according to the course chosen.
  • FIGS. 32 to 35 show further examples of the position of the sails in relation to the respective wina direction.
  • the jib boom 30 which is adjusted in the direction of the boat axis 56 permits a conventional sail position for the jib 36, the jib 53 and the mainsail 34.
  • the setting angle easily separable at the guide 40 for the all-round traction means 40 'can be set.
  • FIG. 33 it is shown that the optimal sail position that has just been found can simply be turned when the wind is blowing, the position of the sails remaining unchanged with respect to one another. Because a larger bulge of the sails is required for upwind courses, this bulge is optimized by simply changing the sheet lengths.
  • FIG. 34 shows the enlargement of the projected wind flow area that is important for the pre-wind course.
  • this enlargement is achieved by spinnaker and spinaker boom.
  • FIG. 35 shows that the slotted wing position used with advantage in aircraft construction can also be achieved with the pivotable jib boom.
  • the improvement of the propulsion values through better use of the deflection of the current must be bought with a reduction in safety, ie this sailing position entails certain dangers, because lifting the sails during gusts presses the jib against the stage and the mast and that hoped for reduction in strength does not occur. Nevertheless, with steady winds and long blows, this feathering position can contribute to considerable speed gains.
  • FIG. 36 shows the basic overall structure of a multihull boat according to the present invention.
  • the pivotable jib boom 30, as can be seen particularly well in FIG. 36, can be designed as a walkable catwalk with a railing.
  • FIG. 38 shows the arrangement according to the invention of a sword 63 below the boat axis 56. This sword also advantageously serves to achieve the object of the invention defined at the outset.
  • the sword 63 initially opposes the wind transverse force 64 with the greatest lateral force 65.
  • the sword 63 together with the windward hull 2 is hoisted out of the water, so that the lateral wind force 64 which causes the heeling no longer counteracts any lateral force 65 caused by the sword 63.
  • the heeling moment decreases and the boat can return to its normal position more easily.
  • FIG. 39 shows the multihull boat in an already inclined position, the entire weight being shifted to one of the two hulls.
  • the sword 63 were integrated in this fuselage 2, then the entire lateral force 65 would come into play even more.
  • the sword 63 in the middle of the boat, however, it is inevitably hoisted by the heeling movement and no longer allows any lateral force to take effect.
  • the hull 2 is now designed in such a way that it does not allow any significant lateral forces 65 'to take effect, for example as a round frame, then the hull can slide over the water 66 so that the wind force 64 takes away most of the reaction force and the heeling moment is so reduced that the boat quickly returns to its horizontal position.
  • Figures 40 and 41 show a device for pivoting the sword 63 in order to change the immersion depth.
  • the pivoting of the sword 63 which is arranged in a housing 68 at the free end of a tube 67 and is pivotably mounted about a pivot axis 69, is carried out by means of a toothed pinion 70 and a toothed belt 71 or toothed belt 70 guided over this pinion.
  • a toothed pinion 70 which extends with its two ends down into the housing 68 and there cooperates with a ring gear 72 of the top of the sword 63, wherein it is pressed by two deflection rollers 73 against the ring gear 72 of the sword 63.

In this low position, the profiled sword 63 can then also be pivoted about the axis of the telescopic tube 76 as required, thereby increasing the effect as necessary.
  • the tiller of the sword 63 embodied by the telescopic tube 76 penetrates the cockpit of the boat, as can be seen from FIGS. 42 and 43, and is therefore statically well supported, namely at two locations that are relatively far apart.
