Definitions

  • the invention relates to a low-heeled sailboat according to the preamble of claim 1.
  • a sailboat is any ship powered by wind, which is driven by wind, with the help of at least one sail.
  • Sailing boats according to the invention thus include in particular all types of sailing ships, sailboats and sailing yachts.
  • heeling arm means that the sailboat can be driven essentially free of heel under external conditions which are normal for sailing, irrespective of the direction of travel relative to the wind direction and the travel speed.
  • the heeling can cause accidents due to falling objects or persons falling into the water from the sailboat. In the worst case it comes by an excessive lateral force, especially in suddenly increasing wind, to capsize the sailboat.
  • the only hitherto well-known largely non-ajar vessel is the windsurfing board.
  • the mast is connected to the surfboard via an articulated mast base, so that the Mast can be tilted in all directions without the board is crowding.
  • this floating connection requires the surfer to hold the mast constantly so that the mast does not fall over. Therefore, the idea of a hinged mast base is not applicable to sailboats with larger masts or for longer trips.
  • Another disadvantage of the mast foot of a windsurfing board is that the mast is not self-righting.
  • An inventive low-slung sailboat comprises at least one rudder system, at least one fuselage at least one mast and at least one storage device connecting the fuselage to the mast.
  • the mast serves to carry sails, with the help of which wind can be used to propel the sailboat.
  • the sailboat becomes maneuverable.
  • the sailboat comprises at least one hull, but may also include two, three or more hulls, for example in the form of a catamaran or trimaran.
  • the mast is rotatably mounted in a lower portion on the bearing device about a longitudinal axis of the sailboat. At least this distinguishes the sailboat from known sailboats with folding masts whose mast can be folded on a folding device forward or backward, for example, to go under bridges.
  • a longitudinal axis extending in a bow-tail direction of the sailboat axis is referred to, wherein the mast is located substantially above the longitudinal axis.
  • the rotatable mounting decouples mast and fuselage movement.
  • the mast of the wind generated by the wind on the sails carried by the mast lateral force can yield by inclining to the leeward side, without the hull of the sailboat inclines equally. So there is no heeling of the trunk.
  • the bearing device can be, for example, as lying on the longitudinal axis, radially guided by the mast and rigid or to a bolt longitudinal axis of the bolt to be rotatably connected to the trunk connected bolts around which the mast can rotate.
  • the sailboat includes at least one automatic erecting device connected to a lower portion of the power transmission mast for effecting torque on the mast in at least one direction along the longitudinal axis, particularly in the direction that mounts the mast from an inclined position to the vertical orientation of the mast longitudinal axis erects.
  • the lower section refers to a section of the mast which is located near the lower end of the mast in vertical operation of the mast longitudinal axis during normal operation of the sailboat.
  • Automatic means in the context of the invention that the erector works without human intervention in particular, the torque in the event of a time-variable inclination of the mast from the vertical to the respective currently present tendency can be adjusted.
  • the torque caused by the righting device can brake a rotational movement of the mast, keep the mast in a certain position and / or raise the mast in the vertical orientation of its mast longitudinal axis.
  • the erecting device can exert the necessary torque on the mast to erect the mast against a torque generated by the wind-induced lateral force and / or the weight of the mast and the mast carried sail and rigging torque, that is, to turn the mast about the longitudinal axis to a vertical orientation.
  • the mast and the erector can be connected to each other, for example, rigid or via a gear unit.
  • the erecting device can apply the work necessary for erection of the mast optionally at a low force and a long distance or vice versa.
  • the transmission unit may comprise, for example, a gear transmission and / or a pulley.
  • the erecting device prevents the mast from being tilted by the lateral force to a horizontal orientation in which the wind on the sails carried by the mast no longer produces substantially any lateral or propulsive force. Instead, the erector holds the mast in a more or less strongly inclined depending on the wind strength and direction of equilibrium position, as the mast of a prior art sailboat is held by the firmly connected to the mast fuselage together with the hull in a wind dependent inclined position. As soon as the lateral force subsides, for example because the wind decreases, the wind direction changes relative to the direction of travel or the sails are overtaken, the erecting device brings the mast into a vertical orientation.
  • a dynamic embodiment of the erecting device ensures that the mast, at any angle of inclination to the vertical, experiences a balance between torque and lateral force on the one hand and the erecting device on the other hand, and thus can be stable. Due to the automatic design, a quick response to changing conditions, for example in the case of suddenly fluctuating transverse force, for example due to a gust of wind, is made possible, and possible operating errors are avoided.
  • the at least one storage device may be detachably connected by a number of holding means with the at least one hull.
  • the holding means may comprise, for example, clamps and / or screws with which the bearing device is clamped or screwed to the hull.
  • An attachment with retaining means has the advantage that the bearing device can be retrofitted to the hull, for example, to rebuild a previously known sailboat according to the invention.
  • a detachable connection offers the additional advantage that the attachment of the bearing device is reversible.
  • the storage device can thus be removed from the fuselage, for example for maintenance work or for attaching another storage device.
  • the at least one storage device can be connected via support elements, for example by a wood or metal frame, with the at least one hull.
  • the bearing device can advantageously be spaced from the fuselage so that the at least one mast can rotate freely about the longitudinal axis.
  • the at least one storage device may be at least partially integrated in the at least one hull.
  • An integrated bearing device does not increase the air or water resistance of the hull, does not present a disturbing obstacle on deck and does not degrade the aesthetic value of the sailboat.
  • the at least one hull may comprise at least one trunk ballast for shifting the center of gravity of the hull below the waterline.
  • the hull ballast may be, for example, weights of a material of high density, for example lead, which are arranged as low as possible in the hull. It is also a variable hull ballast conceivable, for example by more or less large amounts of water are filled into containers in the fuselage to compensate for different loading conditions of the sailboat.
  • the hull ballast produces a torque urging the hull into a horizontal orientation. As a result, the hull is less easily, for example, deflected by wind and waves from the horizontal orientation and returns automatically in this.
  • the trunk ballast helps to reduce the heeling tendency of the sailboat.
  • At least one sheet of a sail carried by the at least one mast can be fastened on the longitudinal axis to the at least one hull.
  • a sheet joins a sail to the hull of a sailboat to set the feathering position relative to the hull. Due to the fact that the sheet is fixed to the hull on the longitudinal axis, ie on the axis of rotation of the mast, the distance of the sail from the fixing point does not change during a rotary movement of the mast. The feathering is thus preserved and does not need to be readjusted.
  • the sailboat may include at least one decoupling means for electrically decoupling the mast from the hull.
  • the decoupling means may comprise, for example, a coating of the contact surfaces of the mast with the fuselage, the bearing device and / or a connection unit with a material having poor electrical conductivity, for example a plastic, in particular wear-resistant plastic.
  • the decoupling means ensures that a lightning strike into the mast is not transmitted to the fuselage where it could damage electrical equipment and / or injure crewmembers.
  • the invention provides that the mast is electrically connected via an electrical connection with the body of water on which the sailboat floats.
  • the electrical connection is designed according to the invention for carrying a typical for a lightning strike performance and / or has a higher electrical conductivity than the hull enclosing connections of the mast with the body of water.
  • She can, for example an electric line and / or an at least partially conductive keel include.
  • the mast acts as a lightning rod.
  • at least the rigging connected to the fuselage especially within the reach of crew members, electrically insulating or with a lower than the electrical connection Stromleitrichlor or a high electrical resistance formed so that the current flow due to a striking in the mast flash substantially in the body of water takes place.
  • the sailboat may comprise at least one brake unit for controlled deceleration of a rotary movement of the mast.
  • the brake unit is designed as a sliding bearing with sufficiently high frictional force between the sliding bearing and the mast.
  • the friction force can be adjustable, for example, by a variable contact pressure of the sliding bearing to the mast. At low frictional force of the mast moves almost freely, whereby a minimum heeling tendency of the sailboat is achieved. The stronger the frictional force is increased, the more the rotational movement of the mast is delayed, and the heeling behavior of the sailboat approaches the heeling behavior of a previously known sailboat. In this way, the glider can adjust the heeling behavior individually to his preferences and the external conditions, such as wind and wave conditions.
  • the brake unit can also be designed so that it completely prevents the rotational movement of the mast at least temporarily.
  • the sailboat shows the same heeling behavior as a previously known sailboat.
  • the brake unit can be configured in this case as a bolt, which is offset when required parallel to the longitudinal axis radially through the mast and a recess of the fuselage, wherein the recess prevents the bolt form-fitting to a rotational movement about the longitudinal axis.
  • the brake unit prevents the rotational movement of the mast with a small transverse force and releases in the manner of a torque wrench only when a certain torque generated by the transverse force is exceeded.
  • the available wind energy is used as efficiently as possible for propulsion.
  • high lateral forces which would lead to a strong heeling in previously known sailboats, are not transmitted to the hull by the released rotational movement of the mast. This design thus combines optimal performance of the sailboat in light wind with increased safety in - especially sudden - strong wind.
  • the sailboat may include at least one stop for limiting the amplitude of rotational movement of the mast.
  • at least one stop in particular two stops each of which limits the amplitude of the rotational movement to the starboard side and port side of the hull, can be advantageously prevented that the mast tends so far that the mast or sail attached thereto dive into the water or with collide with the hull or superstructures or people on it.
  • the stopper is designed so that it will not be damaged even when hitting a fast moving mast on the stop neither the mast nor the stop.
  • the stop can be elastically deformable, for example made of rubber, or combined with a brake unit which brakes the mast before hitting the stop.
  • the sailboat may comprise at least one sail adjustment device for automatically adjusting the position of at least one sail carried by the at least one mast to a rotational movement of the mast.
  • the sail can be automatically opened when the mast tilts.
  • the sail adjustment device can operate purely mechanically, for example via possibly connected to a transmission cables that connect the mast, the fuselage and a sheet of sail together. But it is also a motorized SegelstellISS conceivable, for example, with a motor that adjusts the sheet, at least one sensor that detects the position of the mast relative to the hull, and a controller that controls the engine using the sensor data.
  • the at least one erecting device can be at least one for power transmission, for example, rigid or via a transmission device, with the lower portion of the at least comprising a mast connected and rotatably mounted about the longitudinal axis counterweight.
  • the counterweight can advantageously be dimensioned and / or arranged such that the common center of gravity of the at least one mast, of the mast supported sail and rigging and the counterweight is below the longitudinal axis.
  • the weight force of the counterweight produces a mast erecting torque, which is the greater, the farther the mast and a rigidly connected counterweight are deflected from a vertical orientation of the mast longitudinal axis. It is thus achieved in the simplest way, in particular without complex and / or error-prone control systems, an automatically and dynamically operating Aufrichtvorraum.
  • the mast is connected to the counterweight via a transmission device, for example a toothed gearing, a small deflection of the mast can effect a large deflection of the counterweight and thus a large torque that raises the mast with appropriate gear ratio translation.
  • a transmission device for example a toothed gearing
  • the longitudinal axis of the mast can be kept at a slight inclination from the vertical, whereby a more efficient implementation of wind power in propulsion of the sailboat is possible than with stronger inclination.
  • the transmission device has a variable ratio, so that the inclination behavior of the mast can be adapted, for example, to environmental conditions and / or preferences of the crew of the sailboat.
  • the at least one counterweight may advantageously consist of a material of high density, for example lead, in order to save space.
  • the counterweight may be disposed within the hull in order not to increase the water and / or drag of the sailboat by external attachments.
  • the counterweight can also be arranged outside the hull, for example, if not enough space is available in the hull.
  • the at least one counterweight can be arranged below the at least one fuselage.
  • the counterweight with the same mass can produce a higher torque raising the mast.
  • the counterweight can thus be lighter and smaller dimensions, which reduce the cost of production and improve the performance of the sailboat due to the lower total mass.
  • a form with low water resistance such as a torpedo or teardrop shape, have.
  • a counterweight disposed below the fuselage can for example be rigidly connected to the mast by guiding the mast through a recess in the fuselage to the underside of the fuselage where it is connected to the counterweight, for example bolted or bolted.
  • the counterweight may include at least one keel.
  • the term keel is, as usual in sailboat construction, used for a mounted on the underside of the hull of a sailboat component whose extension transverse to the direction of travel is small in relation to its extension along the direction of travel and its vertical extent.
  • a keel generally serves to reduce sideways drift and increase the weight stability of a sailboat. Due to the design of the counterweight as keel, the counterweight can act as a righting device at the same time and reduce the drift of the sailboat. As a result, further devices for reducing drift, such as swords or keels, can be dimensioned smaller or even completely eliminated. The sailboat is thus easier and cheaper to construct.
  • the at least one keel may include at least one keel ballast for lowering the center of gravity of the keel.
  • a keel ballast for lowering the center of gravity of the keel.
  • the center of gravity of the keel is displaced away from the longitudinal axis, so that the keel generates a higher upright mast torque for the same mass.
  • the keel ballast may be represented by weights attached to or in the keel, such as lead or other high density material.
  • the at least one counterweight may comprise at least two keels, which are preferably arranged in the manner of a keel keel or Dreierkiels.
  • the same mast-erecting torque can be achieved with less vertical expansion of each keel than with a single keel. This reduces the depth of the sailboat, allowing it to sail in shallower water and easier to transport ashore.
  • the keels are connected in different orientations relative to the mast longitudinal axis, for example Y-shaped with the mast, at least one keel is in a nearly vertical even with inclined mast Orientation. As a result, a large horizontally projected, perpendicular to the direction of travel surface of the keel is achieved, which reduces the drift of the sailboat.
  • the sailboat may comprise at least one connection unit rotatably mounted about the longitudinal axis on the bearing device for connecting the at least one mast to the at least one counterweight.
  • the compound is designed for power transmission and can be, for example, rigid or mediated by a transmission device. Due to the fact that the mast in this embodiment is not mounted directly but indirectly via the connecting unit on the bearing device, the mast, for example for maintenance purposes, can be separated from the hull without interfering with the bearing device.
  • the connecting unit is a rod-shaped or tubular body which is connected at one end in each case, in particular releasably, to the mast and the counterweight.
  • the at least one connecting unit may enclose the longitudinal axis and the at least one body at least on one side and / or be substantially annular.
  • a connection unit enclosing the hull has the advantage that no recess in the hull is necessary for the passage of the connection unit, thus gaining space in the fuselage, increasing the stability of the fuselage and enabling easy retrofitting of previously known sailboats according to the invention.
  • a longitudinal axis and the hull completely enclosing, in particular annular, connection unit offers the advantage of particularly high stability.
  • the at least one connecting unit can be guided in a groove on the outside of the at least one fuselage.
  • the connection unit is installed particularly space-saving and aesthetically inconspicuous and increases the water resistance and aerodynamic drag of the sailboat only slightly.
  • the at least one connection unit can have at least one mast holder for, preferably detachable, connection of the at least one mast and / or at least one counterweight holder for, preferably detachable, connection of the at least one counterweight to the connection unit.
  • Removable connections for example plug-in, screwed or clamped connections, offer the advantage that mast and / or counterweight can be easily separated from the sailboat, for example for maintenance or transport purposes, or to use depending on the purpose of different poles and / or counterweights on the same sailboat.
  • the at least one connection unit may include a number of fasteners, such as hooks or rings for attaching a number of shrouds of the at least one mast to the connection unit.
  • a number of fasteners such as hooks or rings for attaching a number of shrouds of the at least one mast to the connection unit.
  • connection unit may be made of a material of high rigidity and strength, preferably of steel and / or composite material. This ensures that the connection unit can transmit the forces occurring between mast and keel without being deformed or damaged.
  • the at least one mast holder and the at least one counterweight holder can be arranged opposite one another on the connection unit with respect to the longitudinal axis. This symmetrical arrangement a particularly simple construction and high stability is achieved.
  • the at least one bearing device may be configured such that it fixes the at least one mast and / or the at least one connection unit with respect to a longitudinal movement parallel to the longitudinal axis and / or a radial movement perpendicular to the longitudinal axis relative to the at least one fuselage. Preventing longitudinal movement ensures that the driving force generated by the sails carried by the mast is transferred to the hull without loss. The prevention of radial movement prevents unwanted relative movements between the mast and fuselage, which could destabilize the sailboat.
  • the at least one storage device may comprise a number of longitudinal bearings and / or a number of radial bearings, wherein the at least one mast and / or the at least one connection unit is longitudinally positively connected to the at least one fuselage via the longitudinal bearings and / or via the radial bearings with respect to the radial movement is positively connected to the at least one hull.

  • the drive may comprise, for example, a propeller acting transversely to the direction of travel, which is rigidly connected to the mast horizontally under water, in particular on an extension of the mast longitudinal axis.
  • the propeller can produce a mast-erecting torque through the water displaced transversely to the direction of travel and thus support, for example, a keel belonging to the erector, so that the latter can be made smaller. This advantageously results in a weight saving and a reduced draft of the sailboat.
