Description

TECHNICAL AREA

The present invention relates to the field of boating.

More specifically, the invention relates to the field of submerged appendages equipping nautical craft.

More precisely still, the present invention relates to the support means of submerged appendages for nautical machines.

The submerged appendages of nautical craft, sometimes called daggerboards, foils, ailerons or rudders, are parts fixed under the structure of the craft. Generally at the back of the nautical craft, it is a rudder. But also sometimes at the front of the craft, these are fins or foils. The appendages have for example the function of giving the nautical craft stability in heel (drift) and allowing control of the direction (rudder).

For this, the rudders are generally made up of an element located in a general vertical plane which can pivot in order to deflect the flow of water under the hull of the machine to control its direction.

The rudders can also include a flap or a profiled wing, sometimes called foil or hydrofoil, most often completely submerged, generally horizontal in use and the incidence of which can be modified to control the lift of the craft.

Subsequently, the term “appendix” will be used to designate any type of fin, appendage, fin, foil, saffron or equivalent means, without the use of the term “appendix” being considered as limiting.

STATE OF THE ART

Many systems have already been proposed to support the appendages of nautical devices.

A first known system is formed by a system called helmet adapted to allow a lifting of the appendix. This system includes a guide designed to allow vertical translation of the appendix, in order to make it mobile. The maintenance is done by friction of the appendage on wedges provided inside the helmet and / or by the use of mechanical maintenance systems (latch, hook, hook, etc ...). The main drawback of this system is that it cannot fix elements at the ends of the appendix, for example a profiled wing or foil, without having to dismantle them before and after each fitting of the appendix.

A second known system is formed by a mechanical hinge system forming a support for the appendix. This mechanical hinge system, fixed on the infrastructure of the machine and supporting the articulated appendix, allows the rotation of the appendix. The main drawback of this system, however, is to have the appendix always at post, which is a problem especially for recreational vehicles.

A third known system is formed by an assembly called spurs and females and consisting of male and female fittings supporting the appendix. More specifically, the appendages are in this case supported between two pairs of spines and females positioned on the transom of the ship. The main defect of this system is that it does not have the liftable appendage function, which is a problem for recreational vehicles. This system in particular does not protect the appendages during the stages of launching and leaving the water.

A fourth type of known system consists of a guide or helmet with a pivoting appendage. These systems include an axis of rotation between a fixed helmet and the appendix. The main problem with this technology is not to offer the possibility of holding the appendix vertically or even to have a rigid linkage inside the appendix.

PROBLEMS POSED AND BASIS OF THE INVENTION

In the above context, the present invention aims to improve the state of the art and to provide a new appendage support device having advantages over the prior art.

An object of the invention is in particular to propose means making it possible to facilitate the installation and the removal of an appendage, including in the case where the latter is provided with equipment such as a flap forming a bearing plane or else a propeller drive.

The aforementioned aims are achieved in the context of the present invention, thanks to an appendage support device for nautical equipment comprising:

- a support element,

- two jaws linked to the support element, at least one of which is pivotally articulated relative to a vertical axis in use on the support element, the two jaws having internal surfaces complementary to the external surface of the appendage , and

- a reversible means for locking the jaws in the closed position, capable of pinching and holding the appendage in position between the jaws.

The present invention also relates to a system comprising in combination a support device of the aforementioned type and an appendage.

The present invention also relates to nautical craft equipped with an appendage support device and / or a system of the aforementioned type.

The present invention further relates to a method of installing an appendage support on a nautical craft, which support comprises a support element, two jaws linked to the support element, at least one jaw of which is pivotally pivoted relative to a vertical axis for use on the support element, the two jaws having internal surfaces complementary to the external surface of the appendix, and a reversible means for locking the jaws in the closed position, suitable for pinching and holding the appendix in position between the jaws, characterized in that it comprises the step consisting in fixing the support element on the infrastructure of the nautical machine.

The present invention further relates to a method of using an appendix support on a nautical machine, which support comprises a support element fixed on the infrastructure of the nautical machine, two jaws linked to the support element, including at least one jaw pivotally pivoted relative to a vertical axis on the support element, the two jaws having internal surfaces complementary to the external surface of the appendix, and a reversible means for locking the jaws in the closed position, suitable for pinch and hold the appendage in position between the jaws, characterized in that it includes the steps of placing an appendage between the jaws, close them on the appendix and lock them in the closed position using the reversible locking means to install the appendix and alternatively unlock the reversible locking means, open the jaws and remove the appendix.

DETAILED DESCRIPTION OF THE INVENTION

In the appended figures, the appendix (which may be formed of a fin, a rudder, fin, foil, or any equivalent means) is referenced 100.

Furthermore, in the appended figures 8 and 9, the structure of the nautical device to be fitted, schematically represented, is referenced 150.

As indicated above, in the context of the invention, the term appendage must be understood in a general sense encompassing any type of appendages, fins, rudders, fins, foils or equivalent means used on a nautical craft.

As also indicated above, the support device according to the invention, referenced 10 in the figures, comprises a support element 20, two jaws 30, 40 and locking means 60.

The support element 20 is formed of a plate adapted to be fixed to the transom of the craft, for example a ship, a boat or any other floating craft, and formed a support for fixing the appendix 100.

The support 20 can be the subject of numerous embodiments. Its purpose is to support the two jaws 30, 40 with relative pivoting about a vertical axis.

In the appended figures, this axis is referenced schematically O-O.

According to the embodiment shown in Figures 1 to 4, the support 20 is formed of a yoke comprising a vertical core 22 designed to be fixed on the transom of the nautical machine and provided at its ends with two horizontal wings 24 , 26 serving as a support for the vertical axis of rotation.

The invention is not limited to this particular embodiment of the support 20 and extends to all equivalent means.

The two jaws 30, 40 are mounted for rotation about the axis 0-0 on the yoke forming the support element 20.

If necessary, one of the jaws 30 or 40 can be rigidly fixed on the support 20 and only the complementary jaw 40 or 30 mounted for rotation about the vertical axis 0-0 on the support 20.

However, preferably, as illustrated in the figures, the two jaws 30, 40 are mounted in rotation, symmetrically, about the axis 0-0 on the support 20.

The two jaws 30, 40 respectively constitute right and left parts of the helmet.

The articulation means proper of the jaws 30, 40 on the support yoke 20 can also be the subject of numerous embodiments.

According to the embodiment shown in the figures and visible in particular in Figures 5, 6 and 7, the two jaws 30, 40 are provided on their vertical edge 31, 41 adjacent to the support 20, of hinges 32, 42 respectively connected and articulated by a pin or journal 28.

Preferably, each of the two hinges 32, 42 is formed from several alternating and entangled eyelets. More specifically according to the particular and nonlimiting embodiment illustrated in the appended figures, the hinge 32 comprises 4 eyelets 32a, 32b, 32c and 32d and the hinge 42 comprises 3 complementary eyelets 42a, 42b and 42c.

The internal surfaces 34, 44 of the jaws, that is to say the surfaces of the jaws 34, 44 facing each other, are formed by impressions complementary to the external surface of the appendix 100.

More specifically, it is preferably concave surfaces which are symmetrical to one another with respect to a vertical median plane of the device.

More precisely still, the internal surfaces 34, 44 of the jaws 30, 40 are formed by an identical curved horizontal generator over the entire height of the jaws 30, 40.

In other words, the horizontal profile of the internal surfaces 34, 44 of the jaws 30, 40, as well as the profile of the chamber formed between the internal surfaces 34, 44 in the closed position of the jaws 30, 40, remain identical throughout the jaw height 30, 40.

According to the particular and nonlimiting embodiment illustrated in the appended figures, the horizontal generator defining the outline of the internal surfaces 34, 44 is formed of a line of continuous curvature, without inflection point, having a radius of curvature progressively increasing from the vertical section 31, 41 adjacent to the support 20, towards the opposite vertical section 39, 49 on the opening side of the jaws where this generatrix is substantially rectilinear.

In other words, the internal surfaces 34, 44 of the jaws 30, 40 are each delimited by a concave cap towards the interior of the chamber and having a radius of curvature progressively decreasing from one end or the caps are substantially flat and straight towards the opposite end.

The cross section of the chamber formed between the jaws 30, 40 in the closed position thereof, is complementary to the horizontal cross section of the appendix 100. This chamber thus has a cross section in the overall shape of an elongated drop of water longitudinally.

The locking means 60 are designed to ensure reversible locking of the jaws 30, 40 in the closed position.

The locking means 60 can be the subject of numerous embodiments.

It may be a snap-in or toggle system as shown diagrammatically in the appended figures.

Preferably the locking means 60 are adapted to tighten the jaws 30, 40 in the closed position on the appendix 100 by exerting on the latter sufficient pressure to maintain the appendix 100 in position.

More specifically, according to the embodiment shown in the figures, we see locking means 60 which comprise, on the vertical edge 39 of a first jaw 30, opposite the support 20, an element 62 preferably extending at least over the major part of the height of the jaw 30 and formed of a hook having a concavity directed towards the outside of the jaw 30 and on the homologous edge 49 of the second jaw 40, opposite the support 20, a second complementary element 64 adapted to cooperate with the first means 62.

When the two jaws 30, 40 are brought together in the closed position, the element 64 is adapted to come into elastic engagement with the first element 62.

However, the element 64 is adapted to be elastically deformed on command of a user, in order to escape the element 62 and allow the abovementioned locking means 60 to be opened.

According to the particular embodiment shown in the appended figures, the holding and locking element 64 is formed by a sole 65 and a hook 66. The sole 65 is adapted to be fixed on the edge 49 of the jaw 40 The hook 66 emerges towards the inside of the edge 49. It is concave in the direction of the face 44 of the jaw and adapted to cooperate with the complementary hook 62. The element 64 further comprises a foot 67 ensuring the connection between the hook 66 and the sole 65. The foot 67 allows elastic deformation to alternately allow the engagement of the hook 66 with the hook 62 to ensure the locking of the jaws in closed position, and the separation of the hooks 66 and 62 to allow the opening of the jaws.

Preferably, as illustrated in the appended figures, the locking device 60 also comprises an element 68 extending the foot 67 opposite the hook 66, to serve as a lever arm facilitating the elastic deformation of the foot 67 to ensure respectively the setting engaging hooks 62 and 66 and separating them.

Of course, the invention is not limited to the particular embodiment of the locking system 60 which has just been described, but extends to any variant in accordance with its spirit.

Such closing and locking means 60 can be formed by any equivalent means, for example any other toggle system, a system based on complementary velvet and hook means fixed respectively on the edges 39, 49 of the two jaws 30, 40, magnets, etc. for example locking means based on bolts or pins, or even a plurality of such means ...

The term “toggle joint system” is understood to mean a blocking system comprising two levers or articulated rods, which are blocked when an axis of articulation between the two levers or rods exceeds a point of alignment between the three axes of articulation and comes to a stop. Such toggle systems are well known to those skilled in the art. They will therefore not be described in more detail below.

In general, the locking means 60 are formed of complementary means fixed respectively on the jaws 30, 40 and which can be placed manually easily and selectively in engagement or separated.

Where appropriate, the locking means 60 comprise means for adjusting the clamping force of the jaws 30, 40 in the closed position.

According to an advantageous characteristic of the invention, the locking means 60 are also equipped with a frangible element.

The function of such a frangible element is to break when a force greater than a threshold is applied to the appendix 100, in order to ensure the separation of the jaws 30, 40 without risking the deterioration of the most important elements of the system and the more expensive, in particular the appendix 100 and / or the essential elements of the support device, in particular the support element 20 itself and / or the jaws 30, 40.

It will indeed be understood that thanks to the presence of this element liable to rupture, it suffices to replace the latter, in the event of untimely effort applied to the appendix 100 to make the system operational again at a lower cost.

In practice, such a frangible element can be formed from any component or sub-assembly of the locking device 60, for example simply means, such as screws, ensuring the fixing of the locking means 62 and 64 to the jaws 30 and 40. A frangible element can be provided on one or other of the locking elements 62 and 64, or even on these two elements 62 and 64.

According to another advantageous characteristic of the invention, there are provided on the internal surface 34, 44 of the jaws 30, 40, elements 38, 48 in relief, of complementary shape of the appendix 100, having a function of blocking the 'appendix 100.

These complementary shaped means 38, 48 have the objective of making it possible to fix the appendix 100 in position between the jaws 30, 40 closed by preventing any relative vertical translation of the appendix 100 relative to the jaws 30, 40.

According to the particular embodiment shown in the figures, there is thus provided a pin or stud 38 projecting perpendicularly on the internal surface 34 of a first jaw 30 and a complementary blind hole 48, facing, on the internal surface 44 of the other opposite jaw 40.

The pin 38 thus extends along a horizontal axis in use.

As can be seen in the appended figures, the pin 38 aims to pass through an orifice 110 of complementary section formed in appendix 100.

A single port 110 or equivalent means may be provided on appendix 100.

As a variant, a plurality of orifices 110 can be provided distributed over the height of the appendix 100 to allow the appendix 100 to be selectively fixed in a plurality of positions relative to the jaws 30, 40.

Likewise, a single pin 38 projecting from the internal surface 34 of the jaw 30 or a plurality of pins 38 can be provided on this surface 34, to reinforce the securing of the appendix 100, subject to providing a corresponding number of orifices 110 in the appendix 100 and according to the same geographical distribution on the internal surface 34 of the jaw 30.

As a variant, it is possible to provide a vertical guide trough in the appendix 100, adapted to receive the pin 38, or even vertical guide troughs adapted to receive the different pins 38.

According to another advantageous characteristic of the invention, the support device 10 can be equipped with electrical or electronic detection means adapted to switch between two positions depending on whether the jaws 30, 40 are in the open and / or closed position and / or according to whether an appendix 100 is positioned or not between the two jaws 30, 40.

In practice, a micro-switch can be provided for this between the two jaws 30, 40, for example near the edges 39, 49 to detect the open and / or closed positions of the two jaws 30, 40 and a second microphone respectively. -switch positioned on one of the internal surfaces 34, 44 to detect the presence of the appendix 100 or not between the two jaws 30, 40.

Such electronic or electrical detection means detecting the position of the jaws 30, 40 and the presence or not and the position of the appendix 100 deliver open / closed state information. They allow in particular to detect a bad positioning or a stall of the appendix 100.

According to another variant in accordance with the invention, it is possible to provide complementary electrical contacts respectively on at least one of the jaws 30 or 40 and on at least one of the surfaces facing the appendix 100. Such electrical contacts can be used to provide an electrical connection with any electrical equipment placed on the appendix, for example for motor control purposes, connection with sensors, energy distribution and serve for example to control the machine, in particular for navigation engine control.

Represented schematically such electrical contacts in Figure 7 under the reference 80. The representation given in Figure 7 is however in no way limiting as to the number, the arrangement or the configuration of the electrical contacts. In practice at least one of the sets of complementary electrical contacts provided respectively on the jaws 30, 40 or on the opposite appendix 100 is formed of elastic elements in order to guarantee a good quality of contact and electrical connection.

The authorized opening between the two jaws 30, 40 is preferably sufficient to allow the appendage to be removed laterally, either transversely to its longitudinal axis and not only longitudinally. In other words, the width of the free opening formed between the two jaws 30, 40 is preferably at least equal to the greatest thickness of the appendage considered perpendicular to its median plane of symmetry.

Of course the present invention is not limited to the particular embodiments which have just been described but extends to any variant in accordance with its spirit.

In particular within the framework of the invention, the expression “nautical device” must be understood as encompassing any type of floating device, without being strictly limited to floating devices used for sport or leisure purposes.

Furthermore, as an alternative to manual control of the opening and closing of the jaws 30 and 40, of the vertical movement of the appendix 100 between the jaws 30 and 40 and of the locking and unlocking of the means 60 respectively, it is possible to provide in the context of the invention to equip the device with appropriate respective actuators making it possible to produce, by appropriate motorizations and if necessary in response to a remote control, at least some movements of opening and closing of the jaws 30 and 40, for vertical displacement of the appendix 100 between the jaws 30 and 40 and for locking and unlocking the means 60 respectively.

Such actuators are known per se and will therefore not be described in more detail below.

To ensure automated movement in the vertical direction of the appendix 100, it suffices for example to provide a rack or the like on the appendix and opposite, at the support element 20 or the jaws 30, 40 an associated motorized pinion .

The appendix 100 shown diagrammatically in FIGS. 1 to 4 consists of a rectilinear element having a constant horizontal cross section over its entire height. The invention already finds an interesting application with type of appendage because it offers many advantages in the handling of such an appendage, compared to the prior art.

However, as can be seen in FIG. 8, in the context of the present invention, the appendix 100 can be provided with different equipment. The invention then offers even greater advantages because it facilitates the installation and removal of the appendix despite the presence of this equipment.

Such equipment makes it possible for example to perform functions such as the appendix 100 does not only serve as a rudder for directing the trajectory of the machine.

To this end, the appendix 100 can be provided, for example at its lower end or in the vicinity of its lower end, with a propeller 120 associated with a motorization 130.

As can also be seen in the appended FIGS. 8 and 9, the appendix 100 may be provided with a flap 140 forming a generally horizontal support plane, at its lower end or in the vicinity of its lower end, or even in an intermediate position over its height. .

A modification of the incidence of this flap 140 or of the position of movable fins integrated in the flap makes it possible to control the lift of the machine.

Those skilled in the art will understand that despite the presence of these elements 130, 140 forming a large projection relative to the horizontal cross section of the appendix 100, the support system according to the present invention, thanks to the opening of the jaws 30, 40, allows easy installation and removal of the appendix 100, without having to dismantle and remove the equipment 130, 140 from the appendix 100.

FIGS. 8 and 9 show equipment provided at the base, that is to say at the bottom, of appendix 100.

However, the invention also applies to appendages comprising equipment at their upper part, for example a housing housing a motorization (thermal or electric), batteries, an electronic control module or any other required equipment.

A motorization provided in the upper part of the appendix 100 can for example be connected to a propeller carried by the lower part of the appendix 100, by a linkage which descends in the appendix to the propeller.

Those skilled in the art will understand that there again, despite the presence of such equipment which prohibits removal of the appendage by sliding downwards, the opening of the jaws 30, 40 authorized within the framework of the invention, allows simple and easy manipulation of the appendix whether in an installation phase or in a removal phase.

The system according to the invention makes it possible to perform numerous functions thanks to appendix 100, in particular:

. a ship steering function (shown diagrammatically by the arrow D in FIG. 9), the appendix 100 then constituting a rudder,. a lift function of the ship (shown diagrammatically by the arrow P in FIG. 9) thanks to the flap 140,. a propulsion function of the ship (shown diagrammatically by the arrow Pr in FIG. 9) using the propeller 120 placed at the base of appendix 100,. if necessary, a control of the lift by means of a command, for example by linkage associated with the flap 140 constituting the bearing plane, (shown diagrammatically by the arrow A in FIG. 9),. where appropriate, an automatic servo-control function thanks to the use of suitable servo-motors, for controlling at least one of the displacements provided within the framework of the present invention,. a possible lifting function of the appendix 100 by opening the jaws 30, 40, (shown diagrammatically by the arrow R. in FIG. 9). a “fuse” function avoiding risks of deterioration of sensitive parts of the system thanks to the presence of a frangible element (shown diagrammatically by the arrow F in FIG. 9),. a function for detecting the position of the jaws 30, 40 and the presence of the appendix 100 by virtue of the above-mentioned electrical detection connectors, and. a command / feedback function thanks to the presence of electrical contacts, such as connection pins, complementary on the appendix 100 and on the facing surfaces of the jaws 30, 40, allowing interaction / exchange with the different elements arranged / connected / contained on appendix 100 (motor, sensor, servo controls).

The device according to the invention offers numerous advantages over the state of the art.

The support system in accordance with the invention makes it possible in particular to propose an accountable appendage without dismantling the equipment such as carrier plane 140 and propeller propeller 120.

The support device according to the present invention makes it possible in particular to easily remove the appendix transversely after opening the jaws 30, 40.

The means constituting the invention can be made of any suitable material, plastic, metal and / or wood and according to any suitable technique, for example by resin molding.

The invention applies in particular, but not exclusively to sailboats comprising an appendage or motorized ships.
