Plateforme navale comportant une superstructure comprenant une ouverture d'accès à une niche  Naval platform comprising a superstructure comprising an access opening to a niche
La présente invention concerne une plateforme navale. The present invention relates to a naval platform.
Plus particulièrement, l'invention se rapporte à une plateforme navale du type comportant une superstructure comprenant au moins une ouverture donnant accès à une niche comme décrite dans le document EP 2 433 859.  More particularly, the invention relates to a naval platform of the type comprising a superstructure comprising at least one opening giving access to a niche as described in document EP 2 433 859.
Cette ouverture est généralement équipée de moyens d'obturation escamotables, déplaçables entre une position active d'obturation de l'ouverture et une position escamotée de dégagement de cette ouverture.  This opening is generally equipped with retractable closure means, movable between an active position of closing the opening and a retracted position of release of this opening.
Différentes raisons ont amené les concepteurs et les constructeurs de ce type de plateformes, à intégrer de plus en plus dans les superstructures, et en particulier dans les flancs de ces superstructures, des ouvertures permettant d'accéder à des niches de celles-ci.  Various reasons have led the designers and builders of this type of platform, to integrate more and more in the superstructures, and in particular in the sides of these superstructures, openings to access niches thereof.
Ces niches sont par exemple adaptées pour recevoir des embarcations rapides et des moyens de mise à l'eau et de récupération de celles-ci.  These niches are for example adapted to receive fast boats and launching means and recovery thereof.
D'autres installations et/ou équipements peuvent bien entendu être installés dans de telles niches.  Other facilities and / or equipment can of course be installed in such niches.
Pour différentes raisons et par exemple des raisons de sécurité et de protection du personnel embarqué et des raisons de discrétion notamment thermique ou de signature équivalente radar (SER), ces ouvertures sont équipées de moyens d'obturation escamotables.  For various reasons and for example reasons of safety and protection of personnel on board and reasons of discretion including thermal or radar equivalent signature (SER), these openings are equipped with retractable closing means.
Dans l'état de la technique, de très nombreux modes de réalisation de ces moyens d'obturation ont été proposés.  In the state of the art, very many embodiments of these sealing means have been proposed.
C'est ainsi par exemple que l'on peut retrouver dans des plateformes de l'état de la technique, des moyens d'obturation qui se présentent sous la forme d'un ou de plusieurs volets articulés, déplaçables entre une position d'obturation et une position de dégagement d'ouverture.  For example, it is possible to find, in platforms of the state of the art, closure means which are in the form of one or more articulated flaps, movable between a closed position. and an opening release position.
Ces déplacements peuvent par exemple être assurés par des moyens de motorisation électriques.  These displacements can for example be provided by means of electric motorization.
Différents modes de fixation de ces volets les uns sur les autres et sur le reste de la structure de la plateforme, ont également été proposés.  Different ways of fixing these shutters on each other and on the rest of the structure of the platform, have also been proposed.
Différents matériaux ont également été proposés comme par exemple des matériaux métalliques, composites..., pour fabriquer ces volets.  Various materials have also been proposed such as metal materials, composites ..., to make these shutters.
D'une façon générale, toutes ces structures présentent un certain nombre d'inconvénients notamment au niveau de leur complexité, de leur poids, de leur coût, de leur furtivité visuelle, des risques de corrosion en raison du fait qu'ils sont soumis à des agressions liées à l'environnement extérieur, etc .. In general, all these structures have a certain number of drawbacks in particular as regards their complexity, their weight, their cost, their their visual stealth, risks of corrosion due to the fact that they are subjected to attacks related to the external environment, etc.
Le but de l'invention est donc de résoudre ces problèmes.  The object of the invention is therefore to solve these problems.

L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant aux dessins annexés, sur lesquels :  The invention will be better understood on reading the description which follows, given solely by way of example and with reference to the appended drawings, in which:
- la figure 1 représente une vue schématique de côté d'une plateforme navale selon l'invention, et comportant une superstructure comprenant un flanc muni d'au moins une ouverture,  FIG. 1 represents a schematic side view of a naval platform according to the invention, and comprising a superstructure comprising a sidewall provided with at least one opening,
- la figure 2 représente une vue de derrière en perspective illustrant la structure d'un exemple de réalisation de moyens d'obturation entrant dans la constitution d'une plateforme selon l'invention,  FIG. 2 represents a rear perspective view illustrating the structure of an exemplary embodiment of closure means forming part of a platform according to the invention,
- la figure 3 illustre une vue en coupe d'un détail de moyens de guidage entrant dans la constitution de ces moyens d'obturation,  FIG. 3 illustrates a sectional view of a detail of guiding means forming part of the constitution of these closure means,
- la figure 4 illustre de façon schématique un motoréducteur entrant dans la constitution de tels moyens d'obturation, et  FIG. 4 schematically illustrates a geared motor forming part of the constitution of such closing means, and
- la figure 5 représente une vue de côté d'une plateforme illustrant des tôles de masquage servant à assurer la continuité des furtivités visuelle, thermique et électromagnétique entre la plateforme navale et les moyens d'obturation.  - Figure 5 shows a side view of a platform illustrating masking plates for ensuring the continuity of visual, thermal and electromagnetic furtivities between the naval platform and the sealing means.
On a en effet illustré sur la figure 1 , une plateforme navale qui est désignée par la référence générale 1 .  It has indeed shown in Figure 1, a naval platform which is designated by the general reference 1.
Cette plateforme navale comporte une superstructure, désignée par la référence générale 2, et qui comprend par exemple dans son flanc visible sur cette figure, au moins une ouverture donnant accès à une niche.  This naval platform comprises a superstructure, designated by the general reference 2, and which comprises for example in its visible side in this figure, at least one opening giving access to a niche.
Sur cette figure 1 , cette ouverture est désignée par la référence générale 3 et donne donc accès à une niche ménagée dans le flanc correspondant de la superstructure.  In this figure 1, this opening is designated by the general reference 3 and thus gives access to a recess formed in the corresponding side of the superstructure.
Cette ouverture 3 est associée à des moyens d'obturation escamotables désignés par la référence générale 4 sur cette figure, qui sont donc déplaçables entre une position active d'obturation de l'ouverture et une position escamotée de dégagement de cette ouverture.  This opening 3 is associated with retractable closure means designated by the general reference 4 in this figure, which are therefore movable between an active position of closing the opening and a retracted position of clearance of this opening.
Ceci permet alors d'ouvrir ou au contraire de fermer cette niche et donc de mettre celle-ci en relation avec l'environnement extérieur ou au contraire de l'isoler de cet environnement. Bien entendu de nombreux emplacements et de très nombreux modes de réalisation de cette ouverture de la superstructure et de la plateforme navale peuvent être envisagés. This then makes it possible to open or on the contrary to close this niche and thus to put it in relation with the external environment or on the contrary to isolate it from this environment. Of course, many locations and many embodiments of this opening of the superstructure and the naval platform can be envisaged.
Selon l'invention, les moyens d'obturation de l'ouverture comportent un rideau en matériau textile, associé à des moyens d'enroulement et de déroulement horizontal de ce rideau, disposés de part et d'autre de l'ouverture de la superstructure, pour obturer ou dégager l'ouverture.  According to the invention, the closure means of the opening comprise a curtain made of textile material, associated with winding and horizontal unwinding means of this curtain, arranged on either side of the opening of the superstructure , to seal or clear the opening.
On a en effet illustré par exemple sur la figure 2, un exemple de réalisation de tels moyens d'obturation.  For example, FIG. 2 illustrates an exemplary embodiment of such closure means.
En fait, sur cette figure 2, l'ouverture de la superstructure est toujours désignée par la référence générale 3 et les moyens d'obturation sont toujours désignés par la référence générale 4, la superstructure étant quant à elle toujours désignée par la référence générale 2.  In fact, in this FIG. 2, the opening of the superstructure is always designated by the general reference 3 and the closure means are always designated by the general reference 4, the superstructure being always designated by the general reference 2 .
Comme cela est illustré, les moyens d'obturation de l'ouverture comportent alors un rideau en matériau textile, désigné par exemple par la référence générale 5 sur cette figure 2.  As illustrated, the closure means of the opening then comprise a curtain of textile material, designated for example by the general reference 5 in this FIG.
Ce rideau peut alors être plein ou ajouré et présenter des caractéristiques notamment techniques de résistance à l'environnement et de discrétion et de protection, appropriées à ce type d'utilisations.  This curtain can then be full or openwork and have characteristics including technical resistance to the environment and discretion and protection appropriate for this type of use.
Ce rideau 5 est alors associé à des moyens d'enroulement et de déroulement de celui-ci, qui sont disposés de part et d'autre de l'ouverture 3 pour obturer ou dégager cette ouverture.  This curtain 5 is then associated with winding means and unwinding thereof, which are arranged on either side of the opening 3 to close or clear this opening.
Ces moyens d'enroulement et de déroulement du rideau d'obturation 5, sont désignés par exemple respectivement par les références 6 et 7 sur cette figure 2.  These winding and unwinding means of the shutter curtain 5 are designated for example respectively by references 6 and 7 in this FIG.
En fait, ces moyens d'enroulement et de déroulement du rideau 5, comportent un premier et un deuxième tambours de stockage et de déstockage du rideau, constitués par exemple respectivement par les tambours désignés par les références 7 et 6 sur cette figure 2.  In fact, these winding and unwinding means of the curtain 5, comprise a first and a second drums for storing and retrieving the curtain, constituted for example respectively by the drums designated by the references 7 and 6 in this FIG.
Ces tambours de stockage et de déstockage du rideau 6 et 7, sont alors disposés de chaque côté de l'ouverture.  These drums of storage and retrieval of the curtain 6 and 7, are then arranged on each side of the opening.
Le tambour 7 est par exemple apte à recevoir le rideau textile en position stockée escamotée de dégagement de l'ouverture.  The drum 7 is for example able to receive the textile curtain stored stored retracted position of the opening.
L'autre tambour 6 est associé par exemple à au moins un câble de traction du rideau. Ainsi par exemple, le tambour 6 est relié à deux câbles de traction 8 et 9, associés à l'extrémité libre du rideau textile 5, pour dérouler celui-ci et donc déplacer ce rideau vers sa position active d'obturation de l'ouverture. The other drum 6 is associated for example with at least one pulling cable of the curtain. For example, the drum 6 is connected to two traction cables 8 and 9, associated with the free end of the textile curtain 5, to unroll it and thus move the curtain to its active position of closing the opening .
Dans ce cas, le ou les câbles de traction 8 et 9 du rideau, sont associés par exemple à une barre de traction 10, fixée sur l'extrémité correspondante avant du rideau 5, pour permettre le déroulement de ce rideau et sa mise sous tension à travers l'ouverture.  In this case, or the traction cables 8 and 9 of the curtain, are associated for example with a drawbar 10, fixed on the corresponding front end of the curtain 5, to allow the unwinding of the curtain and its power through the opening.
Ainsi cette barre de traction 10 comporte par exemple à ses extrémités, des moyens de guidage respectivement 1 1 et 12, adaptés pour coopérer avec des moyens de guidage complémentaires respectivement 13 et 14, s'étendant le long des bords supérieur et inférieur de l'ouverture, pour guider le déplacement du rideau à travers l'ouverture de la superstructure.  Thus, this drawbar 10 comprises, for example at its ends, guide means respectively 1 1 and 12, adapted to cooperate with complementary guide means respectively 13 and 14, extending along the upper and lower edges of the opening, to guide the movement of the curtain through the opening of the superstructure.
De plus et comme cela est illustré par exemple sur la figure 3, les bords supérieur et inférieur du rideau peuvent également comporter des moyens de guidage et de mise sous tension.  In addition and as illustrated for example in Figure 3, the upper and lower edges of the curtain may also include guide means and power.
Ces moyens de guidage peuvent se présenter par exemple sous la forme de ralingues et de tunnels de ralingues ou de trains de galets ou autres.  These guide means may be for example in the form of ropes and tunnels of ropes or trains of rollers or others.
Par exemple, le rideau 5 peut comporter sur ses bords supérieur et inférieur, une ralingue par exemple 14, qui est alors associée à un tunnel de ralingue par exemple 15, de la plateforme, pour assurer le guidage des déplacements de ce rideau et sa mise sous tension.  For example, the curtain 5 may comprise on its upper and lower edges, a rope for example 14, which is then associated with a luff tunnel for example 15, of the platform, to guide the movements of this curtain and its implementation under pressure.
Ces tunnels de ralingues sont également par exemple associés à des moyens de réglage de leur position ce qui permet par exemple de régler la tension appliquée au rideau.  These lug tunnels are also for example associated with means for adjusting their position which allows for example to adjust the tension applied to the curtain.
Chaque tambour 6 et 7 décrit précédemment, est associé également par exemple à un motoréducteur électrique ou autre, tel que celui illustré sur la figure 4 et désigné par la référence générale 17.  Each drum 6 and 7 described above is also associated for example with an electric geared motor or the like, such as that illustrated in FIG. 4 and designated by the general reference 17.
On conçoit alors qu'en position escamotée, le rideau textile 5 est enroulé autour du tambour de stockage et d'enroulement 7 et que l'ouverture 3 de la superstructure de la plateforme est alors dégagée.  It is then conceivable that in the retracted position, the textile curtain 5 is wrapped around the storage and winding drum 7 and that the opening 3 of the superstructure of the platform is then disengaged.
Lorsque l'on souhaite obturer cette ouverture, un opérateur actionne l'alimentation du motoréducteur associé au tambour 6.  When it is desired to close this opening, an operator actuates the power supply of the geared motor associated with the drum 6.
Celui-ci se met alors à tourner en enroulant le ou les câbles de traction 8 et 9 du rideau et donc en provoquant l'avancée et le déroulement du rideau 5 à partir du tambour 7.  This then begins to turn by winding the traction cable or cables 8 and 9 of the curtain and thus causing the advance and unwinding of the curtain 5 from the drum 7.
Le rideau se rapproche alors de la position d'obturation de l'ouverture. Juste avant l'obturation totale de l'ouverture, le motoréducteur associé au tambour 7 est alimenté pour assurer en fin de course une parfaite tension horizontale de la toile. The curtain then approaches the shutter position of the opening. Just before the total closure of the opening, the geared motor associated with the drum 7 is fed to ensure at the end of the race a perfect horizontal tension of the fabric.
Lorsque l'on souhaite ouvrir et dégager l'ouverture, l'opérateur déclenche l'alimentation du motoréducteur associé au tambour 7, pour enrouler le rideau d'obturation autour de celui-ci et donc l'escamoter et dégager l'ouverture correspondante de la superstructure.  When it is desired to open and clear the opening, the operator triggers the supply of the geared motor associated with the drum 7, to wind the shutter curtain around it and thus retract it and release the corresponding opening of the superstructure.
Différents modes de fonctionnement du système dans son ensemble peuvent être envisagés.  Different modes of operation of the system as a whole can be envisaged.
En particulier un mode de fonctionnement de secours des moyens de manœuvre peut être prévu.  In particular, a mode of emergency operation of the operating means can be provided.
Dans ce cas le motoréducteur peut comporter une empreinte de réception d'un système d'accouplement avec une perceuse ou une visseuse/dévisseuse par exemple pneumatique, pour permettre une manouvre du rideau même en cas de panne par exemple d'alimentation électrique.  In this case the geared motor may include a receipt of a coupling system with a drill or a screwdriver / screwdriver for example pneumatic, to allow a manouvre curtain even in case of failure eg power supply.
Bien entendu d'autres modes sont envisageables.  Of course other modes are possible.
Un tel rideau SER est également compatible avec des opérations de sauvetage (SOLAS) grâce notamment à sa rapidité d'ouverture.  Such a curtain SER is also compatible with rescue operations (SOLAS) thanks to its speed of opening.
On notera que des capots de protection peuvent être disposés par exemple autour de ces tambours pour assurer la sécurité de fonctionnement de ceux-ci et la sécurité et la protection du personnel embarqué.  It will be noted that protective covers may be arranged for example around these drums to ensure the operational safety of these and the safety and protection of the personnel on board.
Il peut également être prévu des tôles de masquage périphérique autour de l'ouverture, afin d'assurer une continuité des performances de furtivité notamment visuelle, thermique et électromagnétique entre la plateforme navale et les moyens d'obturation de l'ouverture, en assurant par exemple le masquage des interstices entre ceux-ci.  It may also be provided peripheral masking plates around the opening, to ensure a continuity of stealth performance including visual, thermal and electromagnetic between the naval platform and the closure means of the opening, ensuring by example the masking of the interstices between them.
Ceci est par exemple illustré sur la figure 5, où l'on a illustré de telles tôles respectivement 18, 19, 20 et 21 .  This is for example illustrated in Figure 5, where there is illustrated such sheets respectively 18, 19, 20 and 21.
Il va de soi bien entendu que de très nombreux autres modes de réalisation encore peuvent être envisagés.  It goes without saying of course that many other embodiments can be envisaged.
