Abstract

The invention relates to an assembly of a mounting system (43) and rudder (44) for mounting the rudder to the hull (11) of a boat (1). The assembly comprises: a frame (442) which is mounted on the hull (11) from a first mounting element and a second mounting element; and a rudder body (441) which is slidably mounted in the frame (442) to allow adjustment of the depth of the rudder (44). The rudder (44) has a hydrofoil (45). The rudder body supports the hydrofoil (45) at one of the ends of said rudder body, and wherein the rudder body is suitable for being arranged in the frame (442) with either the hydrofoil (45) oriented upwards, i.e. above a waterline of the boat (1), or the hydrofoil (45) oriented downwards, i.e. below a waterline of the boat (1).

Description

Title: Mounting system and rudder assembly, support plane installation kit comprising such an assembly and method of changing the configuration of a boat comprising such a kit

Technical area

The invention relates to the field of installing rudders on boats.

The invention thus relates more precisely to a system for mounting a rudder to the hull of a boat, an assembly comprising such a mounting system and a rudder and method for installing a rudder.

State of the prior art

During coastal navigation, it is not uncommon for a part of the boat, such as the rudder, to encounter an obstacle, such as the bottom or a rock or unidentified floating object. Such an encounter may result in damage to said part.

Such a risk is particularly present with regard to rudder and it would be beneficial to have a system to limit the risks linked to coastal obstacles.

A solution to this problem is the provision of a rudder comprising a frame and a body mounted sliding in said frame to allow, through this sliding, an adaptation of the depth of the rudder depending on the configuration of the bottom. However, if such a sliding assembly makes it possible to adapt the depth of the rudder according to the risks involved, it does not provide protection against an unpredictable obstacle, such as a sandbank or an orphaned rock.

There is therefore a need to provide systems which would make it possible to limit the risks linked to coastal obstacles which do not require adjustment as is the case with such a sliding assembly.

According to another problem of the prior art, there are support plan installation kits for boats which each include: - two supporting plane arms intended to be fixed on a structural element of the boat and each having a supporting plane intended to be at least partly submerged when the arm equips the boat,

- one or more rudders each equipped with a supporting plane, for example T-shaped.

Such kits make it possible to transform a “classic” boat into a boat with supporting planes (or, according to its English name which is generally used, “hydrofoils”), or hydrofoils.

These kits nevertheless have a relatively significant drawback in that they do not allow a rapid transition of the boat from the hydrofoil configuration to the classic configuration. Indeed, if it could be possible to simply dismantle the supporting plane arms to allow passage into a classic configuration, the or each rudder must necessarily be replaced by a classic rudder, that is to say without a supporting plane. Thus, in addition to the difficulty of dismantling the rudder, it is necessary for the boater to have access to one or more rudders without a supporting surface.

Thus, there would be an interest in providing elements of such a kit which would facilitate the transition of a boat from a hydrofoil configuration to a classic configuration and which would avoid the problems of complete dismantling of the rudder as presented by the installation kits for supporting planes of the prior art.

Presentation of the invention

In certain configuration of the invention, it aims to remedy the above drawback and thus aims to provide a system making it possible to offer protection to the rudders in the event of encountering an obstacle such as a rock, the bottom or an unidentified floating object.

In some of these configurations, the invention relates in particular to a system for mounting a rudder to the hull of a boat, the mounting system comprising: a first and a second mounting element by means of which the rudder is intended to be mounted to the hull of the boat, the first and the second mounting element being intended to be mounted movable in rotation with respect to the hull of the boat around a rudder axis which is common to them, the second mounting element being intended to be arranged along the rudder axis under the first mounting element when the boat is afloat, the first element of assembly having a pivot axis along which the rudder is intended to be mounted movable in rotation, the pivot axis being transverse to the rudder axis, and the second mounting element being intended to be assembled to one of the rudder and the hull by elastic interlocking.

The invention aims more particularly to facilitate the transition from a hydrofoil configuration to a conventional configuration and to avoid the problems of complete dismantling of the rudder.

To this end, the invention relates to a mounting system and rudder assembly for mounting the rudder to the hull of a boat from said mounting system, the mounting system and rudder assembly comprising: a first and a second mounting element by means of which the rudder is intended to be mounted to the hull of the boat, the first and the second mounting element being intended to be mounted movable in rotation with respect to the hull of the boat around an axis of rudder which is common to them, a frame mounted on the first and second mounting elements, a rudder body mounted sliding in the frame to allow adjustment of the depth of the rudder.

The rudder has a carrier plane, said carrier plane being preferably a T-shaped carrier plane, and the rudder body carries the carrier plane at one of the ends of said rudder body and the rudder body being adapted to be arranged in the reinforcement with either the supporting plane oriented upwards, that is to say above a waterline of the boat, or the supporting plane oriented downwards, that is to say above below a waterline of the boat.

In this way, with such a configuration; rudder can easily switch from a “hydrofoil” configuration, in which the supporting plane is located under the waterline, to a classic configuration, that is to say in which the supporting plane is out of water by a simple change of arrangement of the rudder in the frame. In addition, with such a configuration, the rudder can be used in both configurations of the boat, thereby eliminating the need for two separate rudders.

The second mounting member may be intended to be arranged along the rudder axis below the first mounting member when the boat is afloat, the first mounting member having a pivot pin along which is intended to be mounted movable in rotation the rudder, the pivot axis being transverse to the rudder axis, the second mounting element being intended to be assembled to one of the rudder and the hull by elastic fitting.

The second mounting element may be intended to be assembled to the rudder by elastic fitting.

The mounting system may further comprise an intermediate part intended to be fixed to the hull, and advantageously to the transom of the hull, and in which the first and the second mounting element are mounted movable in rotation with respect to the intermediate piece around the rudder axis.

In this way only the intermediate piece can be specific to the boat to be fitted, the first and second mounting elements can be standard elements of a rudder installation kit.

The rudder may have a depth portion arranged on one end of the rudder intended to be opposite the hull, and in which said depth portion comprises an element made of deformable material, such as an elastomer which is advantageously a natural or synthetic rubber.

In this way, in the event of encountering an object causing the rudder to pivot around the pivot axis, the risk of damage to the rudder at said end is reduced.

By “carrying plane” or “carrying planes”, it is understood, above and in the rest of this document, a profiled element to provide a lift force to the boat that it equips, such elements are also known under the name “wings” bearings” or even “lifting planes”, or, according to the more usual English name “foils” or “hydrofoils”, and equip boats of the “hydrofoil” type (or in English “hydrofoil”).

With such a supporting plane, the rudder can participate in the elevation of the boat when the latter has a “hydrofoil” configuration.

In accordance with the invention, the rudder body carries the supporting plane at the level of one of the ends of said rudder body and the rudder body is adapted to be arranged in the frame with either the supporting plane oriented upwards, c that is to say above a waterline of the boat, or the supporting plane oriented downwards, that is to say below the waterline of the boat.

With such a configuration, the rudder can equip the boat both when it is configured for “hydrofoil” navigation and when it is configured for “classic” navigation.

The invention further relates to a kit for installing supporting planes for a boat, in particular wind-powered, a boat comprising at least one structural element, the kit for installing supporting planes comprising an assembly according to the invention and at least one supporting plane arm intended to be mounted on the structural element and having a supporting plane intended to be at least partly submerged.

The invention further relates to a method of mounting a rudder to the hull of a boat from a system according to the invention, the method comprising the following steps of: mounting on the hull of the first and the second element mounting elements movable in rotation with respect to the hull of the boat around a rudder axis which is common to them, the second mounting element being arranged along the rudder axis under the first mounting element when the boat is afloat, mounting the movable rudder in rotation around a pivot axis of the first mounting element, the pivot axis being transverse to the rudder axis, the second mounting element being assembled to one of the rudder and the hull by elastic interlocking.

Such a method allows the assembly of a rudder using a mounting system according to the invention and to benefit from the advantages linked thereto. The invention further relates to a method for changing the configuration of a rudder of a boat equipped with a carrier plane installation kit according to the invention, the method for changing the configuration comprising the following steps: removal of the rudder of the frame, passage of the orientation of the rudder from one configuration among a configuration in which the supporting plane oriented upwards and a configuration in which the supporting plane oriented downwards, to another configuration among the configuration in which the supporting plane oriented upwards and the configuration in which the supporting plane oriented downwards, arrangement of the rudder in the frame while maintaining the orientation in which it was passed.

A step of modifying a configuration of the at least one supporting plane arm can also be provided in such a way as to change from one configuration to a configuration in which the second supporting plane is at least partly immersed and a configuration in which the second supporting plane is not immersed to the other configuration among the configuration in which the second supporting plane is at least partly immersed and the configuration in which the second supporting plane is not immersed.

Detailed presentation of particular embodiments

Figures IA and IB illustrate a boat 1, here a catamaran, equipped with an installation kit for supporting planes 22, 32, 45, 55 incorporating a rudder mounting system according to one possibility of the invention so that the latter forms a hydrofoil.

It will be noted, of course, that if in the context of this embodiment, the installation kit for supporting planes 22, 32, 45, 55, and therefore the mounting system according to the invention, equips a boat 1 of type catamaran, this can be adapted to other types of boats, such as a monohull or a trimaran, as will be shown in the following embodiments.

The boat 1 comprises a structural element 15, here one of the connecting arms 15, 16, on which part of the installation kit for supporting planes 22, 32, 45, 55 is installed.

An installation kit for supporting planes 22, 32, 45, 55 according to the present embodiment comprises, as shown in Figure 2: two support blocks 21, 31 each intended to be fixed to the at least one structural element 15 , that is to say one of the connecting arms 15, 16 of the boat 1, two supporting plane arms 22, 32 each having a supporting plane 24, 34 intended to be at least partly immersed, each supporting plane arm 22, 32 being mounted on a support block 21, 31 which is respective to it, two rudders each equipped with a 45, 55 T-shaped supporting plane.

It should be noted that, according to an advantageous and optional possibility of the invention, shown in Figure 2, the installation kit of supporting planes can also include a control system 17 capable of communicating with a system for modifying the motorized configuration, not shown, and control said system to adapt the arrangement of the supporting plane arms 22, 32. Note nevertheless, in a usual configuration of the invention, the arrangement of the supporting plane arms 22, 32 is adjusted manually by a member of the crew of boat 1.

The support block 21, 31 comprises, as shown in Figure 3: two adaptation parts 212A, 212B, shaped to cooperate with the structural element 15, 13 and be fixed to the latter, the adaptation parts providing a plane reference for the supporting plane arm 22, a plate 211 on which the supporting plane arm 22 is mounted, the plate 211 being mounted on the adaptation parts 212A, 212B along the reference plane.

As shown in Figure 3, in the present embodiment, two adaptation parts 212A, 212B are provided consisting of two half-shells sandwiching the structural element, that is to say the arm connection 15. The first adaptation part 212A, “top” part, has an L shape, while the second adaptation part 212B, “bottom” part, has a U shape in order to best accommodate the lower part of the connecting arm 15. Such a conformation allows the adaptation parts 212A, 212B, from the shape of the portion of the connecting arm 15 which they house, to provide a reference plane, with respect to -screw of the waterline of the boat, for the plate 211 and therefore the supporting plane arm 22 which is mounted on the plate 211. As shown in Figure 3, the U shape of the second adaptation part 212B forms a housing so as to stabilize its placement on the connecting arm 15, and that of the first adaptation part 212A. Note that the surface of the first adaptation part 212A which is opposite the deck of the boat defines the reference plane.

Each of the first and second adaptation parts is preferably made of a rigid material such as a thermoplastic, a composite material or even wood.

It will of course be noted that if in the present embodiment, said surface of the first adaptation part 212A materializes the reference plane, this plane may not present materiality, since by the provision of a support surface , not necessarily flat, the adaptation part(s) 212A, 212B make it possible to ensure the orientation of the plate 211, and therefore of the supporting plane arm 22, with respect to the waterline of the boat 1.

According to one possibility of the invention shown in Figure 3, the first adaptation part 212A can have a recess in order to authorize the placement of an adjustment system 213 of the orientation of the supporting plane arm 22 on the plate , said adjustment system 213 comprising a gear assembly to allow height adjustment of the ball joint(s) 215, 216, illustrated in Figures 4A and 4B.

In accordance with Figure 3, in the present embodiment, the plate 211 has a complementary shape with the adaptation parts 212A, 212B. Thus, the plate 211 has a U shape with the two branches of the U which define a housing shaped to receive the adaptation parts 212A, 212B. The fixing of the plate 211 on the adaptation parts 212A, 212B is done by elastic fitting and by translation along the axis of the connecting arm of the boat. The plate 211 thus makes it possible to ensure good fixing of the adaptation parts 212A, 212B on the connecting arm 15. It will of course be noted that such elastic fitting is only an example of mounting the plate 211 on the adaptation parts, any other assembly, such as screwing, riveting or welding can be considered. It should nevertheless be noted that in the context of the invention, a removable assembly is to be preferred.

Each plate is preferably made of a rigid material such as a thermoplastic, a composite material, wood or even metal and in particular stainless steel. Each support plane arm 22, 32 comprises, as shown in Figures IA and IB, comprises a fixing arm 23, 33 by which the support plane arm 22, 32 is mounted on the plate 211, and a support plane 24, 34 as such which, by being fixed to one end of the fixing arm 23, 33, is intended to be at least partly submerged. The supporting plane 24, 34 is profiled in order to provide a lift force when the boat 1 moves. Of course, if in the present embodiment, the support arm 23, 33 and the support plane 24, 34 are distinct from each other, it is possible to provide a one-piece support plane arm 22, 32 with the support arm 23, 33 and the supporting plane 24, 34 which are then formed integral with each other.

Each supporting plane arm 22, 32 can be mounted on the corresponding plate 211 from at least two ball joints 215, 216, 217. In this first embodiment, as shown in Figures 4A and 4B, each plane arm carrier 22, 32 is mounted on the corresponding plate 211 from a first and second ball joints 215, 216 located on either side of the supporting plane arm in order to define a first pivot connection and another ball joint 217 which is arranged at one end of the supporting plane arm 22, 32 which is free from the supporting plane 24, 34 this with a lateral offset to define a second pivot connection with the second ball joint 216. The first ball joint 215 is mounted movable in translation vis- with respect to the plate 211 in order to allow adjustment of the “height” of the first ball joint 215. In this way, an adjustment of its height, from the adjustment system 213, allows the supporting plane arm 22, 32 to pivot around the second pivot connection and thus to adjust the orientation of the supporting planes with respect to the connecting arm 15 and therefore the boat 1. It will be noted that according to one possibility of the invention, the third ball joint 217 can be dismountable in such a way as to allow the supporting plane arm to pivot around an axis defined by the first and second ball joints 215, 216 when it is disassembled from the third ball joint 217.

As also shown in Figures 4A and 4B, a complementary support 214 can be provided, for example arranged on a deck of the boat 1, complementary in order to provide an additional fixing point for the supporting plane arm 22, 32. According to this possibility , the supporting plane arm 22, 32 can be fixed to this complementary support 214 from a sliding pivot connection as provided, by example and as illustrated by Figures 4A and 4B, from a strap 214A attaching the supporting plane arm 22, 32 to said complementary support 214.

As shown in Figures IA and IB, the installation kit for carrier planes 22, 32, 45, 55 according to the present embodiment also includes two rudders 44, 54 each equipped with a T-shaped carrier plane 45, 55. In order to allow the boat 1 to be maneuvered, each of the rudders is extended by a bar 42, 52 which is respective to it.

By T-shaped supporting plane, we mean above that the supporting plane 45, 55 comprises two profiles extending in the extension of one another and on either side of the rudder body thus forming the high bar of a capital “T” with the body of the rudder which forms the body of the T.

According to one possibility of the invention illustrated in Figures 5A and 5B, each rudder 44, 54 is mounted on a respective hull 11, 12 of the boat 1, and more precisely on the transom of said hulls 11, 12, by means of a mounting system 43. The mounting system 43 comprises an intermediate part 431 fixed to the transom, and a first and a second mounting element 432, 433 by means of which the rudder 44, 54 is mounted to the hull 11, 12 of the boat 1, the first and the second mounting element 432, 433 are mounted movable in rotation with respect to the intermediate part 431, and therefore to the hull of the boat, around a rudder axis which is attached to them. common. The second mounting element 433 is arranged along the rudder axis below the first mounting element 432 when the boat 1 is afloat.

Note that, according to the principle similar to the adaptation parts 212A, 212B, the intermediate part 431 is adapted according to the shape of the transom to be equipped. Thus, in the kit, to allow the installation of each rudder, only the intermediate part 431 has to be adapted to the boat 1 to be equipped, the other elements concerning the rudder including in particular the first and second mounting elements can be standardized.

According to a variant of the invention, the first and second mounting elements 432, 433 can be adapted to the boat 1 which they equip, the first and second mounting elements 432, 433 then being directly mounted on the hull 11, 12 (or in this case at the transom of said hull) around a rudder axis.

The first mounting element 432 has a pivot axis 432A along which the rudder 44 is movably mounted in rotation, the pivot axis 432A being transverse to the rudder axis and is, preferably and more precisely, substantially perpendicular to the axis. rudder. More specifically, the first element 432 has on a first portion a through orifice in which the rudder axis passes (lock or needle, depending on the rudder configuration, as discussed below) and on a second portion two others orifices through which the pivot pin 432A passes. The pivot pin 432A is transverse to the rudder pin.

The second mounting element 433 is assembled to one of the rudder 44 and the hull 11 (through the intermediate piece 431), here the rudder 44, by elastic fitting. Of course, according to a variant not illustrated, the mounting element 433 can be assembled intermediate piece 431, therefore the hull, by elastic snap-fastening, this elastic snap-fastening then also making it possible to provide a movable assembly in rotation around the rudder axis . To allow such elastic mounting, the second mounting element 433 has on a first portion a through orifice through which the rudder axis passes and on a second portion comprising two arms each having a cantilevered tongue, the arms together defining a reception space for a rudder fixing member 44 preferably having a relief face.

It will be noted that if the first and second mounting elements 432, 433 are provided in the form of two independent parts, it is also possible, without departing from the scope of the invention, that the first and second elements of assembly 432, 433 are supplied in the form of a single part. Likewise, if the first and second elements 432, 433 are mounted in the present embodiment, pivoting around the rudder axis forming the rudder stock, it is also possible that the first and second elements 432, 433 are mounted on the intermediate piece 431, or even the hull, by means of a respective needle, the first and the second element then each forming a femelot. According to a possibility not illustrated, the first element 432 can be mounted removable on the hull, this making the first element 432 free to pivot around the pivot axis 432A and to disengage from the rudder axis, or rudder. In this way, when the user wishes to remove the rudder in order to store it, he can disengage the first element and disengage the second element from its attachment by elastic engagement so as to separate the rudder 44, 54 from the hull 11, 12.

The rudder 44, as shown in Figure 5A, comprises: a frame 442 by which the rudder 44 is mounted on the first and second mounting elements 432, 433, rudder body 441 slidably mounted in the frame 442 in order to allow an adjustment of the depth of the rudder 44, a securing system, such as a pin, in the position of the rudder body 441 on the frame 442, not shown.

The frame 442 has a first and a second extension, extending towards the shell 11, 12, from which the frame is respectively mounted on the first and the second mounting element 432, 433. The first extension is pivotally mounted around the pivot axis 432A. The second extension forms the fixing member and preferably presents, as shown in Figure 5B and towards the shell 11: two grooves extending on either side of the second extension in a direction parallel to the axis rudder, configured to each accommodate a respective cantilevered tongue of the second mounting element 433, a flush face, to facilitate the introduction of the second member into the reception space defined by the second mounting element.

With such mounting of the rudder 44 on the hull of the boat, when the rudder encounters an obstacle, such as the bottom or a rock or an unidentified floating object, the forces applying to the rudder 44 due to this encounter will cause a dislocation of the second extension with respect to the second mounting element 433 and a pivoting of the rudder 44 around the pivot axis 432A in a direction opposite to the movement of the boat 1 thus making it possible to limit the risks of damage to the rudder 44.

In the context of the present embodiment and the invention, the rudder body 441 has a supporting plane 45 here in a T shape. Of course, if such a supporting plane 45 is linked to the use of a mounting system in the frame of a kit for installing carrier planes 22, 32, 45, 55, such a rudder mounting system 43 is perfectly usable, according to a possibility not included in the scope of the invention, for the assembly of a simple rudder not having a supporting plane or not using a frame 442 since such a mounting system offers both a protective function and ease of handling of the latter, regardless of its configuration.

In order to allow the inclination of the carrier planes 45, 55 fitted to the rudders 44, 54 to be adjusted, in the context of the invention, it is possible to provide a system for adjusting the incidence of the carrier plane, not shown. Such an angle of attack adjustment system can be accessible on the bar 32, 42 associated with said rudder 44 or even directly accessible on the rudder 44, the adjustment then being made either on the ground or by raising the rudder 44.

As shown in Figure 5C, according to a particularly advantageous possibility of the invention in the context of such a mounting system, the rudder 44 can comprise a portion of depth 443 arranged on one end of the rudder 44 intended to be opposite the hull and at the front of the latter, in a direction of movement of the boat 1. The depth portion 443 comprises an element made of deformable material, such as an elastomer which can be, for example, a natural or synthetic rubber. Such a depth portion 443 comprising a deformable material, such as an elastomer, makes it possible to absorb part of the forces exerted on the rudder 44 when the latter encounters an obstacle.

According to the invention, as will be discussed in connection with Figures 9A and 9B, the rudder body 441 has two installation orientations in the frame 442, one with the supporting plane 45 arranged on the bottom of the rudder 44 , that is to say below the waterline of the boat, and the other with the supporting plane arranged on the top of the rudder 44, that is to say above the waterline. In this way, with such a 441 rudder body, the rudder 44 can be used as part of a hydrofoil configuration, that is to say with the supporting plane 45 arranged on the bottom of the rudder 44, as in a classic configuration, that is to say with the supporting plane 45 arranged on the top of the rudder 44. For this, as shown in Figure 5D, the shape of the rudder body can be adapted with each end 441A, 441B of the body which is configured to provide the guiding function of the boat that is his.

It will be noted that, in accordance with the possibility illustrated in Figure 5C not shown in Figure 5D, the end 441A of the rudder 44 not equipped with a supporting plane (that dedicated to the "classic boat" configuration) can also be provided with a element made of deformable material, such as an elastomer which may be, for example, a natural or synthetic rubber.

Note that to facilitate adjustment of the orientation of the rudder, the bar 42, 52 can be fixed to the frame 442. In this way, it is not necessary to assemble/disassemble it when changing the orientation of the rudder. rudder 44.

According to such a variant, a method of changing the orientation of the rudder can be provided comprising the following steps: disengagement of the second mounting element 433 from its elastic fitting in order to allow pivoting of the frame around the axis of pivot 432A, pivoting of the rudder 44 around the pivot axis 432A in order to bring it to an orientation close to horizontal and removal of the securing system in order to allow the rudder body 441 to slide in the frame 442, removal of the rudder body 441 from the frame 442 and turning of the latter in order to change its orientation, installation of the rudder body 441 in the frame 442 with the new orientation, securing the positioning of the rudder body 441 in the frame 442 by reinstalling the security system. It will be noted that in the context of the invention, an installation kit for supporting planes 22, 32, 45, 55 according to this first embodiment can be installed according to an installation method comprising the following steps: fixing the two parts adaptations 212 on the structural element 15, that is to say the connecting arm 15, fixing of each of the plates 211 on the corresponding adaptation part 212 along the reference plane defined by the latter, each adaptation part 212 and the corresponding plate 211 participating in the formation of the corresponding support block 21, 31, mounting of each of the supporting plane arms 22, 32 on the respective plate 211, assembly, for each of the rudders 44, 54 and on the corresponding hull 11, 12, of the first and second mounting elements 432, 433 movable in rotation with respect to the hull 11, 12 of the corresponding boat 1 around a rudder axis which is common to said elements of mounting 432, 433 this by means of the intermediate piece 431, the second mounting element 433 corresponding to said rudder 44, 54 being arranged along the rudder axis under the first mounting element 432 corresponding when the boat 1 is afloat , mounting of each rudder 44, 54 movable in rotation around the pivot axis 432A of the first corresponding element 432, said pivot axis 432A being transverse to the corresponding rudder axis, each second mounting element being assembled to the rudder by elastic interlocking.

Figures 6A and 6B illustrate the assembly of a supporting plane arm 22 according to a second embodiment. A support plane installation kit 22, 32, 45, 55 according to this second embodiment differs from a support plane installation kit 22, 32, 44, 55 according to the first embodiment in that the supporting plane arm 22 is mounted on the plate 211 from the first and the second ball joint 215, 216 which are both movable in translation with respect to the plate 211, the plate being devoid of third ball joint 217 and in that the supporting plane arm 22 is fixed to the support complementary 214 from a sliding pivot connection provided by a strap 214A attaching the supporting plane arm 22 to said complementary support 214.

In this second embodiment and for each supporting plane arm 22, 32, the first and second ball joint 215, 216, by equipping the end of said supporting plane arm 22, 32 free of the supporting plane, together define an axis of pivoting of the supporting plane arm 22, 32 with respect to the structural element 15.

In this way, when each supporting plane arm 22, 32 is released from the strap 214A which provides the sliding pivot connection to the complementary support 214, said supporting plane arm 22, 32 is able to tilt with respect to the structural element, here the connecting arm 15 and thus be raised out of the water. Such tilting makes it possible to limit the handling constraints of the boat 1 when it is brought ashore for storage or in heavy weather not compatible with a hydrofoil configuration.

Figures 7 to 8B illustrate a monohull boat 1 equipped with a support plane installation kit according to a third embodiment. An installation kit for supporting planes 22, 32, 45, 55 according to this third embodiment differs from an installation kit for supporting planes 22, 32, 45, 55 according to the second embodiment in that a single adaptation part 212 and a single plate 211 are provided forming a single support block on which the two supporting plane arms 22, 32 are mounted, in that the deck 13 of the boat 1 forms the structural element, in that the supporting planes 34 bearing plane arms 22, 32 are T-shaped supporting planes and in that the fixing of the adaptation part on the bridge 13 is obtained by means of a strap 218 passing through the part d adaptation 212 and going around the hull 11.

It will be noted that this strap 218, as shown in Figure 7, in this third embodiment in which the support plan installation kit equips a monohull boat 1, can come to bear on the keel 14 in such a way as to improve the fixing the adaptation part on the bridge 13. The adaptation part 212 and the plate 211 extend over the entire width of the bridge 13.

Figures 8A and 8B show the mounting of each of the supporting plane arms 22, 32 on the single plate 211. It can thus be seen that in this third embodiment, in a manner similar to the second embodiment, each arm of plan carrier 22, 32 is mounted on the plate 211 using a first and a second ball joint 215, 216 arranged at one end of the carrier plane arm 22, 32 which is free from the carrier plane by together defining an axis pivoting, which is here provided by means of a pivot 216A connecting the first and second ball joints 215, 216. Of course, such a pivot 216A, as is the case for the second embodiment, is not necessary and the first and second ball joints 215, 216 are capable of providing such mounting without the pivot being necessary.

In a manner identical to the second embodiment, the first and the second ball joint 215, 216 are both movable in translation with respect to the plate 211. To do this, the adjustment system 213 comprises two gears, not referenced, geared together and integral in rotation with respectively the first and second ball joint 215, 216. As shown in Figure 8B, one of the gears is provided with a pulley intended to be coupled with a winch, not shown, by the use of a belt, not shown. Alternatively, the pulley can be operated manually by a simple rope kept under tension acting as a belt. In this way, manipulation of the winch makes it possible to rotate the two gears in a counter-rotating movement which in turn causes a movement of the first and second ball joints 215, 216 with respect to the plate 211 which is opposite each other and therefore a pivoting of the supporting plane arm 22, 32.

Each supporting plane arm 22, 32 is also mounted on the plate 211 by means of the complementary support 214 of the supporting plane arm on which the supporting plane arm 22, 32 is mounted by means of a removable sliding pivot connection such as that provided by strap 214A. Such a sliding pivot connection does not hinder the pivoting of the supporting plane arm 22, 32 when adjusting the height of the first and second ball joints 215, 216 with respect to the plate 211 by means of the adjustment system 213. It will be noted that in this third embodiment, in order to allow stable placement with respect to the plate, the complementary support has a base having a surface complementary to the upper surface of the plate 211. Figures 9A and 9B respectively illustrate a boat 1 equipped with two rudders 44, 54 according to the invention in a hydrofoil configuration and in a classic boat configuration.

It can be seen that in the hydrofoil configuration illustrated in Figure 9A, in accordance with the invention, each rudder 44, 54, and therefore their body 441 are arranged in the corresponding frame 442, 542 with the supporting plane 45 oriented downwards. , that is to say below the waterline of the boat 1. In an identical manner the supporting plane arms 22, 32 are arranged with their respective supporting plane 24, 34 which is submerged.

In the classic configuration illustrated in Figure 9B, in accordance with the invention, each rudder 44, 54, and therefore their body 441 are arranged in the corresponding frame 442, 542 with the supporting plane 45 oriented upwards, this is that is to say above the waterline of the boat 1. In an identical manner the supporting plane arms 22, 32 are arranged with their respective supporting plane 24, 34 raised, that is to say outside of the sea.

The passage of the boat 1 from one configuration to another can be done according to the following process: removal of each rudder 42, 52 from the corresponding frame 442, 542, changing the orientation of each rudder 42, 52 from one configuration among a configuration in which the supporting plane 45, 55 oriented upwards and a configuration in which the supporting plane 45, 55 oriented downwards, to another configuration among the configuration in which the supporting plane 45, 55 oriented toward the top and the configuration in which the supporting plane 45 faces downwards, arrangement of each rudder 42, 52 in the corresponding frame 44, 54 while maintaining the orientation in which it was passed, passage of each of the plane arms carrying a configuration among a configuration in which the supporting plane 24, 34 corresponding to said arm is at least partly immersed and a configuration in which the supporting plane 24, 34 corresponding to said arm is not immersed in the other configuration among the configuration in which the supporting plane 24, 34 corresponding to said arm is at least partly immersed and the configuration in which the second supporting plane 24, 34 corresponding to said arm is not immersed. This last transition from one configuration to another of the supporting plane arms can be done, as is permitted in the embodiments of the present invention, by tilting the supporting plane arms as shown in Figures 9A and 9B.
