    Folding system of floats for sail or motor trimarans or other multi-hull vessels. System of folding of floats, for trimarans or other multi-helmets, where each float (2) and its arms (3) form a rigid solid that to be folded approaches the central hull (1) describing a substantially horizontal trajectory, thanks to that the arms are released from the central hull and are lifted along a guide (5) substantially vertical solidarity with the boat's rail and thanks to a tensioner (10) that goes from the middle of the arm to an interior point of the embroiders of the central hull (1) and that rises pivoting on said point.

    [0002] Float folding system for sail or motor trimarans or other multi-hull vessels.
    [0003]
    [0004] Object of the invention
    [0005]
    [0006] With this patent we propose a system for folding floats for sail or motor trimarans that wish to reduce their sleeves. They could also be used by boats with central helmets with more than one float. It is designed to ideally be able to use mooring spaces for monohulls. In order for this to happen, the trimaran sleeve already folded should not be larger than the seats normally used for monohulls of the same length. In order that the folding can be done while the trimaran is still afloat and without loss of stability, the floats must approach the central hull describing a substantially horizontal trajectory. In order that, even being foldable, the trimaran can sail with any time, the set formed by each float and by the arms that join it to the central hull must be monolithic. And in order for the trimaran deck to be used by its crew when the floats are already folded, the float arm assembly should not invade the central hull beyond the candlesticks.
    [0007]
    [0008] BACKGROUND OF THE INVENTION
    [0009]
    [0010] The float folding systems used by Dragonfly, Kurt Huges, Astus, etc. are already well known, but we do not consider them of interest because they are unnecessarily complicated, fragile, and expensive. We could use the old and well-known Farrier - Corsair system where the float and its arms form a rigid solid, but the great invasion of the central hull by arms and tensioners after folding makes the use of its cover very uncomfortable by the crew in the mooring plaza.
    [0011]
    [0012] Description of the invention
    [0013]
    [0014] Due to all this we propose a new system of folding, of our invention and absolutely new, that does not have the disadvantages of those known up to now. Like the Farrier - Corsair system, the float and its arms are joined together forming a rigid solid and there is a lower tensioner that goes from the central part of each arm to the side of the ship. But there the resemblance ends. Instead of lifting the free end of the arms by means of an upper tensioner like in the Farrier - Corsair system, in our system the free end of the arm, and thanks to a "guide", it rises following a more or less straight trajectory and more or less vertical, which avoids that the roof of the central hull is invaded.
    [0015]
    [0016] Description of the drawings
    [0017]
    [0018] To complement the description that will be made below and in order to help a better understanding of the characteristics of the invention, according to a preferred embodiment of the same, a set of drawings is included as an integral part of said description. where, with illustrative and non-limiting character, the following has been represented:
    [0019]
    [0020] Figure 1 shows the half of a section of a trimaran equipped with the folding system for its floats, all made in accordance with the object of the invention, and in the position of deployment of the floats.
    [0021] Figure 2 shows a view similar to that of Figure 1, but in which the process of folding the float in three steps and its situation once folded is shown. The horizontal trajectory of the lower part of the floats is observed.
    [0022] PREFERRED EMBODIMENT OF THE INVENTION
    [0023] In view of the figures outlined, it can be seen how the following elements participate in the trimaran of the invention:
    [0024] (1) Central helmet
    [0025] (2) Float
    [0026] (3) Arm or arms
    [0027] (4) Tensioner
    [0028] (5) Guide
    [0029] (6) Tension joint / central hull
    [0030] (7) Tension / arm joint
    [0031] (8) Guide / arm joint
    [0032] (9) Security fixation
    [0033] (10) Reinforcement tensioner
    [0034] Figure 1 shows a monolithic assembly formed by a float (2) and one or more arms (3), a tensioner (4) that links the arm (or arms) (3) to the central hull through respective end joints. a guide (5) that forces the inner end of the arm (3) to perform an ascending and more or less vertical movement during the folding process, this guide being (5) a rail, a pusher, an endless screw, a combination of rail and pusher, or rail and worm, etc. We also have the necessary joints of the tensioner with the central hull (6), the tensioner with the arm (7), and the guide with the arm (8).
    [0035] It is essential the additional participation of some "security fixation" (9) that ensures that the arm is not released from the central hull when the ship is sailing, and finally a "tensor of respect" (10), which will be discussed more ahead.
    [0036] Figure 2 shows the process of folding the float in four phases, with a movement from left to right:
    [0037] In a first phase the float (2) would be open. While in the second and third the float (2) would approach getting more vertical and would be approaching the central hull. In the final phase of folding, the float (2) would already be fully folded, and as we can see with hardly any intrusion of the cover of the central hull by the elements of the system. By designing the system properly, especially the position and shape of the guide (5), it is possible to achieve that the bottom part of the float (2) moves completely horizontally.
    [0038] The folding system just described, however, has a disadvantage. And, due to the nature of the system, the tensioner (4) has to be very short and it has to join the arm (3) at a point too close to the central hull and it also has to pull with a angle too small. All this forces the arms to absorb too great efforts. To compensate for this, we suggest the convenience of using a second reinforcement tensioner that goes from a point near the area of union of the arm with the float to a point located far below in the central hull. This second tensioner, or "reinforcement tensor" (10), would have a greater lever arm and pull with a much greater angle.This reinforcing tensioner should be able to shrink, bend, be telescopic, or dismantle at the time of folding. It could also be flexible, in which case it can also serve as a mechanism for collecting the shrouds that start from the floats.Figure 1 clearly shows the usefulness of this reinforcement tensor.
