Definitions

  • the invention relates to a safety and stability device in stormy seas for motor boats according to the preamble of claim 1.
  • Such a device is known from document FR-A-1408225 which relates to a new form of pleasure and sports boat (cockpit) which renders the lack of stability without effect, but its irreversibility is conditioned by the fact that it must be used exclusively an overhead propeller engine. If in this embodiment the inventor, instead of putting four fixed arms at ⁇ 90 degrees between them, had arranged four arms which can be distant from each other, as shown in claims 1, 2 and 3 of the invention, and s 'he had developed the features according to legend (A), (G) and (K), he would have solved the problem.
  • the cabin suspended in the air can in no case be submerged and at the same time be irreversible. If the cockpit, with the arms fully extended or fully retracted, immerses in the water any object forming a single body with the cockpit (for example: the outboard) the hulls after a rotation of ⁇ 45 degrees will be prevented in their rotation by the outboard and the device is therefore unusable and, consequently, the boat becomes a normal catamaran.
  • the object of the present invention is to achieve complete irreversibility in all directions for motor boats. This objective is achieved by a device according to the preamble of claim 1 by the characteristics of its characterizing part.
  • the system consists of side shells B which can be two, three, four or more; these shells are of various shapes and sizes. They can, with any system, turn around the central boat I.
  • the device will be provided with an adjustable stroke stop.
  • the maneuver will last 10 to 15 seconds, during which time there will be instability.
  • An oil pump, OPERATED manually, will be installed in the circuit in case the motor pump does not work.
  • the device can be put in position L0 by lengthening the piston G2 and shortening G1-G3.
  • the two Z pistons are used to symmetrically distance the two shells in height; the distance meter "M", in height, will slide inside its housing.
  • the shape of the side shells can vary from that shown in the DES. 10-13.
  • the vertical arms "V” can be extended using a system identical to that of the arms "D".
  • This device can, as we can see if we refer to the DES. 16, adapt to small and large boats.
  • the dotted shells represent the device in the L0 position.

Claims (5)

1. Sicherheits- und Stabilitätsvorrichtung für Motorboote beim Sturm bestehend aus mindestens zwei kreisenden Schwimmern, die mit dem Boot durch zwei Arme verbunden sind, die um zwei Halter rotieren, wobei einer davon an Bug und einer an Heck angebracht ist. Diese Halter befinden sich Longitudinalachse des Bootes und erlauben die freie Rotation dieser Schwimmer um das Boot. (I);
charakterisierend ist außerdem,
daß die Arme untereinander durch ein Kontrollsystem verbunden sind, durch welches man ihre Position verändern kann und somit auch das Tauchniveau der rotierenden Schwimmer, ohne ihre freie Rotierung um das Boot zu beeinträchtigen.
2. Die Vorrichtung wie unter Pantentanspruch 1 beschrieben zeichnet sich weiters dadurch aus, daß die Träger längs der vertikalen Achse gehoben oder gesenkt werden können, unter Beibehaltung ihrer Position längs der horizontalen Achse, die sich in zentraler Lage des Bootes befindet.
3. Vorrichtung laut Patentanspruch 1 oder 2, dadurch charakterisiert, daß das Kontrollsystem für die Position der rotierenden Schwimmer aus hydraulischen Kolben besteht.
4. Vorrichtung laut Patentanspruch 1 oder 2, dadurch charakterisiert, daß das Kontrollsystem für die Position der rotierenden Schwimmer aus Zahnradcrics besteht.
5. Vorrichtung laut Pantentanspruch 1 oder 2, dadurch charakterisiert, daß das Kontrollsystem für die Position der rotierenden Schwimmer eine ruheposition diesr Schwimmer vorsieht, während derselben die Schwimmer nur das Gewicht der Vorrichtung tragen.
