EP3330170B1 - System for roll stabilisation of boats and boat - Google Patents

Description

The invention relates to a system for roll stabilization of a boat about its longitudinal axis with at least two, in the arrangement of the system on a boat left in water or arranged directly above the water surface, the rolling motion by the water resistance counteracting stabilizing elements. Furthermore, the invention relates to a boat with such a system for roll stabilization.

For the purposes of the present invention, the term "boat" refers in particular to motor yachts, sports boats or sailboats, but the invention should not be limited thereto.

A system for stabilizing a boat of this type is already known in the form of hinged Schwertkielen of sailboats or outriggers in sailboats or catamarans. The US 7 789 035 B1 further describes a combination of a boom stabilizer and a standing aid for canoes or kayaks. Also, applications of stability pontoons to increase the stability of ships in heavy cargo operations are known.

However, the known systems have the disadvantage that they must be part of the boat from the beginning, can not be retrofitted, or require disturbing fastening devices on the deck of the boat. In addition, lateral attachment of these systems to the fuselage can negatively affect the flow resistance of the boat. Finally, they are obstructive after catching the boat, since they need appropriate space when the boat is parked outside the water or on a trailer.

Also known from the prior art are ships or boats with moving fuselage parts. The patent EP 1 685 021 B1 describes a vessel with hulls that are essentially controlled by hydrostatic forces. It Specifically, a catamaran with two hulls and a platform connecting the two hulls is listed. The hulls are movably connected to the platform and can be set in two defined positions. To the hulls for this purpose ballast, means for removing the ballast and means for blocking or locking in the desired position of swimming are provided. A similar system, in which individual parts of the fuselage can be adjusted, also describe the WO 9216405 A1 and the DE 10 2011 010 487 A1 ,

A movable design of parts of the hull to stabilize the ship or boat requires a particularly complex and expensive construction and high demands on the reliability must be made because a malfunction can already lead to a capsizing of the boat. In addition, such a system must already be considered and integrated in the construction of the boat. Retrofitting is not possible or only with considerable effort. The object of the invention is therefore to develop a system for roll stabilization of a boat and a boat, which in a particularly simple manner, a roll stabilization can be achieved around the boat's longitudinal axis. The roll stabilization should have the simplest possible structure and be retrofitted even with existing boats.

This object of the invention is achieved by a system for roll stabilization according to claim 1. With respect to the boat, this object is achieved by a boat according to claim 11. Preferred embodiments of the invention are set forth in the subclaims and the following description, each of which individually or in combination may constitute an aspect of the invention.

In particular, the system according to the invention has a base support which is arranged and fastened to the stern of the boat. The roll stabilization then takes place via two or more planar stabilizing elements in the form of stabilizing plates, of which a first stabilizing plate is arranged on the port side of the boat and a second stabilizing plate on the starboard side of the boat. The first and the second stabilizing plate are movably mounted relative to a hull of the boat to the base support and in particular driven electrically or hydraulically, so that the first stabilizing plate in Port direction and the second stabilization plate in the starboard direction outward in a stabilizing position are movable.

The movement can be a pivoting movement or a linear movement, also a rotation about an axis parallel to the vertical axis of the boat is possible. One aspect, however, is that by this movement, the two stabilizing plates are moved outwards, which should then be located just below or on the water surface. A preferred embodiment of the invention has a bathing platform as a basic carrier. The stabilizing plates are then arranged on the underside and movably mounted, in particular in the region of the starboard or port side edge of the bathing platform.

Between the first and the second stabilizing plate on the one hand and the bathing platform on the other hand, the drive, in each case preferably designed as a pivoting mechanism, is provided. The stabilizing plates are pivotable about the pivot mechanisms in each case about axes of rotation extending essentially parallel to the longitudinal axis of the boat. Expediently, alternatively or additionally, a translatory and / or rotational movement can also be realized.

In a preferred embodiment, the stabilizing plates are arranged in the retracted, inactive position under the bathing platform. In this way, the stabilization plates are stowed to save space and do not adversely affect the flow around the boat. Particularly preferably, the first stabilizing plate and the second stabilizing plate each have a width less than or equal to half the width of the bathing platform.

It is furthermore preferable to provide that the first stabilizing plate and / or the second stabilizing plate can be aligned in an adjustment at an angle of +/- 45 ° about an axis parallel to the vertical axis of the boat and more preferably vertically downwards, ie parallel to the vertical axis. This allows stabilization of the boat in the event of swell and suppresses slipping in cross-currents. Depending on the requirements, the stabilizing plates can also be designed and stored and driven so that they also in this position can be rotated about the vertical axis, then they can even be used as an additional control for the boat when needed.

In a particularly preferred embodiment, the first and / or the second stabilization plate in a further position are largely aligned horizontally. The first and / or second horizontally oriented stabilization plate can preferably be arranged at the level of the water surface or are already arranged at the level of the water surface. According to the invention, a height adjustment of the stabilizing plates is also provided. This can be done via the pivoting movement and / or via a horizontal guide.

This has the particular advantage that the width of the boat is increased by the cantilevered stabilization plates and thus a roll stabilization of the boat is achieved about the longitudinal axis. Due to the preferred rear-side arrangement of the stabilization system also a pounding of the boat is reduced to the transverse axis.

In order to increase the weight of the stabilizing plates, the first and / or second stabilizing plate preferably each have a border, which makes it possible to store water at least temporarily. It is expedient to carry out the lateral borders in different heights. These measures additionally support the stabilizing effect of the system.

Preferably, the first and / or second horizontally oriented stabilization plate flush with the bathing platform to extend the useful surface of the bathing platform. It is particularly expedient to provide a support structure under the first and / or second stabilization plate. The support structure is purposefully formed by rectangular support profiles made of steel. The stabilization plates preferably consist of particularly lightweight and stable GRP or plastic. Also preferably, the projections are made with a coating, such as teak.

The listed technical measures high stability of the stabilizing plates is achieved and the cantilevered stabilizing plates can so fully used as an extension of the bathing platform, so also be committed. In addition, they facilitate the access of the boat from the water.

The adjustment of the stabilizing plates is carried out separately or coupled via two independent drive units or via only one drive unit with a coupling device via which the two stabilizing plates are actuated. According to the invention, the actuating force is generated electrically and / or hydraulically. A manual adjustment, for example by a cable or a crank link can be provided in addition or alone. According to the invention, locking devices are also provided in order to lock the stabilizing plates in the desired orientation. The locking devices are preferably arranged on the pivot mechanisms.

For easier adjustment, the surface of swiveling stabilizing plates can also be fitted with motor-adjustable lamellae, which are rotated only after pivoting of the stabilizing plates into a position parallel to the surface of the stabilizing plates. This reduces the water resistance during pivoting of the stabilizing plates.

Preferably, a pivot rod is arranged on the drive unit and the pivot rod can be rotated by the drive unit. At the bathing platform and / or on the hull of the boat, a receptacle is further preferably provided, in which the rod is rotatably mounted. The stabilizing plates are rotatably connected directly or indirectly via a support structure with the pivot rod, so that the pivoting movement can take place. The connection can be made solvable or non-releasable by positive locking, adhesion or material bond.

Depending on the load case and / or design and / or connection of the bathing platform on the hull of the boat is provided according to the invention to attach individual components of the pivot mechanism on the hull of the boat.

Further features and advantages of the invention will become apparent from the following description of preferred embodiments with reference to the drawings.
