Description

The present invention is defined as a fully adjustable system for

  adjust in a frontal plane the position of the saffron of a sailboat in relation to the general surface of the water and whatever the degree of heeling of the same boat. To allow a good laminar flow of fluid from

  and other saffron; in order to significantly reduce the lateral drift in relation to its track, beyond a certain angle of heel. Traditionally sailboats have a directional rudder fixed relative to the vertical (when these yachts are in position allowing them no angle of heel), with a single degree of freedom.

  Some sailboats have two inclined rudders, oriented with a fixed angulation compared to the verticality of the traditional saffron. With the aim of compensating the resistances according to a certain degree determined accommodation. These existing systems have their interests, but do not allow the complete cancellation of resistance to progress and beyond a certain angle of heel no longer provide the correct laminar flow up to the loss of control of the sailboat.

  The device according to the invention makes it possible to remedy considerably these drawbacks mentioned above. It has indeed according to a first feature a large pulley serving as a support for saffron.

  This support pulley can rest on one or more trolleys (s) which goes or will itself or (they) slide on one or more rail (s) if necessary, to accentuate the lateral mobility in a frontal plane, the Saffron orientation in addition to the rotation allowed by the support pulley.

  According to the particular embodiments of the embodiment, the movable part of the support pulley being the actual support of the rudder, and the fixed part is its other component resting at its base on one or more trolleys (s).

  On the anterior or posterior face of the support pulley may be provided to stabilize and define directly and precisely the angulation given to saffron, one or more hoist (s) force multipliers.

  The carriage (s) is or are large enough and wide to support the fixed point (s) of the fixed part of the support pulley. The trolley (s) slide (s) along the rail (s).

  Each rail is provided with a stopper stop system for the arrival of the trolley (s) at each end.

  A hoist system can be fixed on either side of the trolley (s) lo allowing its or their displacement (s) and fixation (s) of its or their position (s) on the rail (s) .

  1 shows in front section and in front view the device of the invention FIG. 2 is a front section and a rear view of the device of the invention FIG. FIG. 4 shows in front section and in rear view the same variant as in FIG. 3 of this device. FIG. 5 shows in front section and in front view a second variant embodiment of this device. FIG. 6 shows in front section and in rear view the variant 5 of FIG. 5 of this device FIG. 7 is a frontal section and a rear view of a third embodiment of this device FIG. 8 is a front section and an anterior view the variant of Figure 8 of this device With reference to these drawings, the system comprises a central saffron (?) whose anterior part e is supported in its upper part, and also a lower part by a hinge (pin and female) type hinge.

  According to a variant not illustrated, the saffron shovel (4) can be supported by a drift well support containing the previously mentioned joint.

  The saffron shovel (4) directional is thus adjustable as a saber drift with a hoist system on the previous support that can raise or lower on a vertical axis.

  On this unidirectional rudder (4), only the upper articulation and or the upper part of the articulation is fixed on the rear face of the central part of the transverse bar (10) situated inside the moving part (5). ) of the support pulley.

  The lower articulation and where the lower part of the saffron articulation (4) is fixed according to the rotation system chosen on a central axis (11) lower vertical and perpendicular to the crossbar (10) previously mentioned. The whole sliding around the circular rail (12) formed by the non-rotating outer portion (6) of the support pulley (1), by the presence of a carriage (13) sliding around the fixed circle serving as rail (12) previously cited at each end of the crossbar (10) and at the most distal end of another support bar (11) perpendicular to the previous (10), fixed at its center and facing downwards. Each carriage (13) is fixed on one of the outermost, right, left and central (lower) faces of this "T" -shaped structure thus allowing the rotational movement of this structure.

  The support pulley (1) is composed of an outer portion without rotational mobility (6) resting in its lower base on a movable carriage (2), rather long and wide enough having a convex shape in order to support it more effectively.

  This carriage (2) with rollers or ball bearings slides along a rail (3) which substantially conforms to the shape of the hull of the boat, in its front plane and extending over the entire width of the latter .

  The most distal and lateral ends of this rail (3) have a stopper (8) on each side of the width covered by this rail (3) in order to stop the body of the carriage (2).

  According to the variant shown in Figures 3 and 4, it may be preferable to add a second rail (14) identical to the previous one with the same carriage (2) sliding in synergy with the first on the underside of the rail (14), and secured integrally to the upper part of the outer or non-rotating part (6) of the support pulley (1). In a goal to ensure the solidity, and a better efficiency of the system. -5.-

  On the anterior face of the support pulley (1) with reference to Figure No. 1, there is the presence of power reduction hoists (7). Hoist (7) having a pulley (15) attached to the cross bar (10) at the distal end thereof.

  The hoist (7) will then be inserted with another pulley (16) located on the non - rotating fixed outer part (6) on the upper half - sphere of the support pulley (1), with a wedge (17) preceding the 'a pulley. A hoist (7) as previously mentioned at its point of origin and its respective termination on each half sphere separated by the vertical axis formed by the saffron blade (4) relative to the initial position of use (saffron ( 4) perpendicular to the rail (3) of the carriage (2) supporting the support pulley (1)). And each of these hoists (7) from their orientation intersect with that of the opposite side at a point forming an "x" in a front view.

  In a sagittal or profile plane, these two hoists (7) previously mentioned intersect and are superimposed on their meeting point and spaced so that no friction between them does not appear during their tensioning.

  The length of each end of the hoists (7) and the position of the pulleys (15, 16) relative to the system are such that a traction exerted upwards by the user on one of the hoists (7) is multiplied and allows to give the desired angular orientation to the saffron (4). As long as the hoist (7) opposite is simultaneously shocked or released simultaneously with each use, and it is retightened and locked at its respective wedge (17) to ensure the angular immobility in the frontal plane of the system. -6.-

  Such hoists (9) are also present on each side of the carriage (2) on which the base of the non-rotating part (6) of the support pulley (1) rests, and joining the ends of the rail (3) in order to allow the lateral displacement, the positioning and the precise stabilization of this carriage (2) on the same rail (3).

  According to a second variant of embodiment shown in FIGS. 5 and 6, the non-rotating part (6) can be located in the inner part of the support pulley (1) which is in this case fixed integrally to one or more wagon (s). ) (2) placed on the anterior face of the non-rotating internal portion (6) of the support pulley (1); and sliding along the rail (s) (3) superimposed (s) in a frontal plane and extended (s) on the width of the sailboat. The outer part of the support pulley (1) consists of moving carriages (13) or a continuous assembly (13) provided with bearings to slide around the rail (12) formed by the perimeter of the circle that forms the inner part (6) of the support pulley (1).

  According to a third embodiment illustrated in FIGS. 7 and 8, the support pulley (1) may have the form of a parabola (inverted half-disc) on which slides a carriage (19) supporting the upper part of the hinge joint saffron (4).

  The lower part is fixed on an axis forming a pivot articulation (20) placed in the center of a transverse bar (10) (forming the base and the diameter of the half disc joining the carriages (2) placed at each end of the diameter of parabolic 1 which slide on the rail (s) (3) allowing the right lateral movement, left of the entire system.

  By way of non-limiting example, the articulated adjustable system of the rudder (4) will have variable dimensions and various other variants, depending on the size and category of sailboats chosen for its use.

  - light sailing - sailboats of liveable type regatta version whose length and width is defined by the architect and or the rules of gauge defined by the French sailing federation.

  lo And or by the class of the series of sailboats.

  The device according to the invention is particularly intended for setting the position of the saffron (4) in particular on racing yachts as well in Olympic routes, coastal sailing, and offshore races; and also adaptable on any boat requiring a traditional directional rudder system.

  This system allows an adjustment at will as fine as possible, appropriate to the list of the sailboat comparing to a fine tuning of the sails during a Competition.
