Definitions

  • the invention relates to the design and production of trimarans, in particular, but not exclusively to sail.
  • trimarans are represented by US-A-4,326,475 and G B-A-1,304,511.
  • the trimaran known from the document cited first comprises, according to the preamble to claim 1, three floats forming a static flotation system of three flotation zones arranged at the top of a triangle and a bridge to which these floats are connected, however, on the one hand, each of the three floats is pivotally mounted relative to the bridge around at least one axis, one of the pivot axes being substantially vertical, on the other hand, at least one float is provided with a fin of operation, which is essentially vertical, which is pivotally mounted relative to this float about a pivot axis and which is provided with a device for adjusting its pivoting.
  • trimarans such as that shown in US-A-4326475
  • these comprise pivot axes, in particular vertical ones
  • the maneuverability of the trimaran is generally deteriorated due to the absence, in these known structures, of stabilizing fins and of devices for adjusting the pivoting of the maneuvering fins correctly adapted to their function.
  • the object of the invention is to remedy the aforementioned drawbacks and its object is to propose new structures capable of achieving the aim of producing trimarans having improved mechanical strength and maneuverability compared to the trimarans known to date.
  • the stabilization fin is either fixed relative to said float, or pivotally mounted relative to the float about a vertical axis, and is then provided with a device for adjustment of its pivoting.
  • the main advantage of the claimed trimaran lies in obtaining both good stabilization of the floats and good maneuverability, due to the simultaneous adoption of the stabilization fins, on the one hand, of maneuvering, 'somewhere else.
  • a support 14 in T is pivotally mounted, around a geometric axis A parallel to the axis Oy, by means of the two parts of the bar 16 of the T which constitute trunnions and rest in bearings 17 fixed on the float 2.
  • the vertical leg 15 of the support 14 constitutes a trunnion and allows the mounting pivoting around a vertical geometric axis B of the arm 6 and of the arm 5, both welded (18) to the same bushing 19.
  • the ends 5a and 6a, opposite the bushing 19, are provided with ball joint ends 20 which are, on the one hand, fixed to the bridge 4 by horizontal axes 21 substantially perpendicular to the arm considered (5 or 6), on the other hand, fixed to the considered arm (5 or 6) by their threaded part (22, 23).
  • a jack 24 is disposed between each arm 6 and the bridge 4 and allows either to adjust the position of said arm relative to the bridge, or to make a flexible suspension, when its active chamber is connected to a gas accumulator under pressure.
  • the rear float 3 is also connected to the deck 4 by means of a support 14 which allows pivoting around axes A horizontal and B vertical.
  • the beam 10 can oscillate around three orthogonal axes (26, 29, 32) and slide parallel to its own axis.
  • Each float is, moreover, provided with substantially vertical fins, contained in the vertical longitudinal plane of symmetry of the float.

Claims (3)

1. Trimaran, umfassend drei Schwimmer (1, 2, 3), die ein statisches Schwimmsystem aus drei an der Spitze eines Dreiecks angeordneten Schwimmzonen bilden, und einen Mittelsteg (4), an dem diese Schwimmer angehängt sind, wobei einerseits jeder der drei Schwimmer gegenüber dem Mittelsteg (4) um mindestens eine Achse verschwenkbar montiert ist, wobei eine (B) der Schwenkachsen im wesentlichen vertikal ist, anderseits mindestens ein Schwimmer mit einem Manövrier-Flossenkiel (36, 41) versehen ist, welcher im wesentlichen vertikal, gegenüber diesem Schwimmer um eine Schwenkachse (37, 42) verschwenkbar und mit einer Einrichtung (38) zum Steuern seiner Verschwenkung versehen ist, dadurch gekennzeichnet, dass:
1) jeder Schwimmer mit einem Stabilisations-Flossenkiel (39, 43) versehen ist, der vertikal hinter der im wesentlichen vertikalen Schwenkachse (B) des Schwimmers angeordnet ist; und
2) die Schwenkachse (37, 42) jedes Manövrier-Flossenkiels (36, 41) im wesentlichen vertikal und vor der Schwenkachse (B) des entsprechenden Schwimmers angeordnet ist.
2. Trimaran nach Anspruch 1, dadurch gekennzeichnet, dass der Stabilisations-Flossenkiel (43) eines Schwimmers gegenüber dem Schwimmer (3) feststehend ist.
3. Trimaran nach Anspruch 1, dadurch gekennzeichnet, dass der Stabilisations-Flossenkiel (39) gegenüber dem entsprechenden Schwimmer um eine vertikale Achse (40) verschwenkbar angeordnet und mit einer Einrichtung (38) zum Steuern seiner Verschwenkung versehen ist.
