Description

La présente invention concerne une civière flottante, destinée notamment à la récupération des blessés en mer, du type comprenant une armature métallique hélitreuillable supportant une plaque en matériau composite assurant la flottabilité de l'ensemble.The present invention relates to a floating stretcher, intended in particular for the recovery of casualties at sea, of the type comprising a metal frame that can be hoisted, supporting a plate of composite material ensuring the buoyancy of the assembly.

De telles civières flottantes sont en particulier utilisées par l'armée ou la protection civile pour récupérer au moyen d'hélicoptères des pilotes blessés tombés en mer. Il existe à l'heure actuelle plusieurs civières de ce genre, mais dont aucune ne donne véritablement entière satisfaction, en raison notamment de leur encombrement relativement important, ce qui pose des problèmes de stockage et de transport.Such floating stretchers are in particular used by the army or the civil protection to recover by means of helicopters of the wounded pilots fallen at sea. There are at present several stretchers of this kind, but of which none gives really whole satisfaction, in particular because of their relatively large size, which poses storage and transport problems.

La présente invention a donc pour but principal de remédier à cet inconvénient et, pour ce faire, elle a pour objet une civière flottante du type susmentionné qui se caractérise essentiellement en ce que la plaque et l'armature sont articulées dans leur partie médiane, afin que l'ensemble puisse être replié sur lui-même dans le sens de la longueur.The main object of the present invention is therefore to remedy this drawback and, to do this, it relates to a floating stretcher of the aforementioned type which is essentially characterized in that the plate and the frame are articulated in their middle part, in order that the assembly can be folded back on itself lengthwise.

Ainsi, la civière présente un encombrement réduit qui facilite à la fois son stockage et son transport en hélicoptère ou à dos d'homme.Thus, the stretcher has a reduced size which facilitates both its storage and its transport by helicopter or on human back.

Dans une forme de réalisation particulière de l'invention, l'armature métallique est essentiellement constituée par un tube principal rigide cintré au niveau de la tête du blessé et dont les deux branches s'étendent sensiblement en parallèle jusqu'au niveau des pieds, chacune des branches de ce tube étant pourvue dans sa partie médiane d'une articulation et d'un moyen de blocage de cette articulation permettant de rigidifier l'armature en position dépliée.In a particular embodiment of the invention, the metal frame is essentially constituted by a rigid main tube bent at the level of the wounded person's head and whose two branches extend substantially in parallel up to the level of the feet, each branches of this tube being provided in its middle part with a joint and a means for blocking this joint making it possible to stiffen the armature in the unfolded position.

De préférence, l'articulation est constituée par une biellette montée pivotante sur chaque portion de branche au moyen d'un axe, tandis que le moyen de blocage est constitué par une bague femelle montée coulissante sur l'une des portions de branche et venant se visser sur une bague mâle, prévue sur l'autre portion de branche, en enserrant la biellette.Preferably, the articulation is constituted by a connecting rod pivotally mounted on each branch portion by means of an axis, while the locking means is constituted by a female ring slidably mounted on one of the branch portions and coming screw on a male ring, provided on the other portion of branch, by enclosing the rod.

Quant à la plaque en matériau composite, elle est réalisée en deux parties rigides reliées l'une à l'autre par deux articulations disposées sur les côtés, un moyen de blocage de ces articulations étant prévu pour rigidifier ladite plaque en position dépliée.As for the plate made of composite material, it is produced in two rigid parts connected to each other by two articulations arranged on the sides, a means for blocking these articulations being provided to stiffen said plate in the unfolded position.

De préférence, l'articulation est constituée par une biellette montée pivotante sur chacune des parties de plaque au moyen d'un axe, tandis que le moyen de blocage est constitué par un profilé en U monté coulissant et venant en prise sur les bords contigus des deux parties de plaque de part et d'autre de l'articulation.Preferably, the articulation is constituted by a connecting rod pivotally mounted on each of the plate parts by means of an axis, while the locking means is constituted by a U-shaped profile mounted sliding and engaging on the contiguous edges of the two parts of the plate on either side of the joint.

Grâce à cet ensemble de dispositions, la civière flottante selon l'invention peut être aisément pliée ou dépliée en fonction des besoins, tout en ayant une très bonne rigidité en position dépliée d'utilisation.Thanks to this set of provisions, the floating stretcher according to the invention can be easily folded or unfolded as required, while having very good rigidity in the unfolded position of use.

Avantageusement, la plaque en matériau composite épouse la forme du tube principal de l'armature et comporte une face supérieure parfaitement plane, tandis que sa face inférieure est munie d'un renflement au niveau de la tête qui se prolonge vers les pieds par deux chevrons longitudinaux parallèles.Advantageously, the composite material plate follows the shape of the main tube of the frame and has a perfectly flat upper face, while its lower face is provided with a bulge at the level of the head which is extended towards the feet by two rafters. parallel longitudinal.

Cette forme particulière de la plaque de matériau composite permet à la civière toute équipée jetée à l'eau de se retourner automatiquement dans le bon sens et de flotter alors dans une position inclinée à environ 45°, ce qui facilite considérablement la récupération du blessé, ce dernier flottant approximativement dans la même position du fait de son gilet de sauvetage.This particular shape of the composite material plate allows the fully equipped stretcher thrown into the water to automatically turn in the right direction and then float in a position inclined at about 45 °, which considerably facilitates the recovery of the injured, the latter floating approximately in the same position due to his life jacket.

De plus, la plaque en matériau composite est fixée de manière amovible sur l'armature métallique au moyen d'un évidement prévu en partie frontale, venant en prise sur la partie cintrée du tube principal, et de deux broches supportées par l'armature et venant en prise dans des perçages latéraux prévues à cet effet dans la plaque au niveau des pieds.In addition, the plate of composite material is removably attached to the metal frame by means of a recess provided in the front part, engaging on the curved part of the main tube, and two pins supported by the frame and engaging in lateral holes provided for this purpose in the plate at the feet.

Il est ainsi possible, une fois le blessé récupéré et ramené à terre, de déverrouiller la plaque de l'armature et de maintenir le blessé sur la plaque afin de l'emmener directement vers des moyens radiographiques, tandis que l'armature peut être équipée d'une nouvelle plaque en vue d'un autre sauvetage. A cet effet, la plaque est avantageusement prévue radiotransparente.It is thus possible, once the injured person has been recovered and brought back to the ground, to unlock the plate of the frame and to keep the injured person on the plate in order to take him directly to radiographic means, while the frame can be equipped a new plate for another rescue. For this purpose, the plate is advantageously provided radiolucent.

De préférence également, l'armature métallique est pourvue à sa partie inférieure d'un tube secondaire de plus faible diamètre, relié au tube principal par des tubes de jonction et s'étendant parallèlement à celui-ci le long de ses deux branches afin de former deux patins de luge, ce tube secondaire étant interrompu au niveau de chacune des articulations du tube principal.Also preferably, the metal frame is provided at its lower part with a secondary tube of smaller diameter, connected to the main tube by junction tubes and extending parallel to the latter along its two branches in order to forming two sledge runners, this secondary tube being interrupted at each of the joints of the main tube.

Ces patins de luge facilitent évidemment l'introduction de la civière chargée du blessé dans l'hélicoptère de sauvetage, sans pour autant entraver sa capacité de pliage.These sledge skates obviously facilitate the introduction of the stretcher responsible for the injured in the rescue helicopter, without hampering its folding capacity.

D'autres caractéristiques et avantages de l'invention ressortiront de la description qui va suivre d'un exemple de réalisation non limitatif, faite en regard des dessins annexés dans lesquels :

La civière représentée sur les figures 1 et 2 se compose principalement d'une armature métallique 1 supportant une plaque en matériau composite 2 qui assure la flottabilité de l'ensemble. Cette civière est en effet destinée à recueillir des blessés ou des naufragés tombés en mer, en particulier des pilotes d'avion. Il va de soi cependant qu'une telle civière peut également être utilisée dans n'importe quel milieu aquatique, lac ou rivière, et ce aussi bien par l'armée que par la protection civile.The stretcher shown in Figures 1 and 2 mainly consists of a metal frame 1 supporting a plate of composite material 2 which ensures the buoyancy of the assembly. This stretcher is indeed intended to collect the wounded or shipwrecked who fell at sea, in particular airplane pilots. It goes without saying, however, that such a stretcher can also be used in any aquatic environment, lake or river, both by the army and by civil protection.

L'armature métallique 1 est essentiellement constituée par un tube principal rigide 3 en inox, cintré au niveau de la partie entourant la tête du blessé, comme représenté en 4, et dont les deux branches 5 s'étendent sensiblement en parallèle jusqu'au niveau des pieds sur une longueur d'environ 2 mètres.The metal frame 1 is essentially constituted by a rigid main tube 3 made of stainless steel, bent at the level of the part surrounding the head of the injured person, as shown in 4, and the two branches 5 of which extend substantially in parallel up to the level feet over a length of about 2 meters.

Conformément à l'invention, chacune des branches 5 du tube principal 3 est pourvue dans sa partie médiane d'une articulation 6 permettant à la civière de se replier sur elle-même, comme représenté sur les figures 3 et 4. Cette articulation 6 est constituée ici par une biellette 7 montée pivotante sur chaque portion de branche au moyen d'un axe 8. Un moyen de blocage constitué par une bague femelle 9 montée coulissante sur l'une des portions de branche 5 et venant se visser sur une bague mâle 10 fixée sur l'autre portion de branche, en enserrant la biellette 7, permet de rigidifier l'armature 1 dans sa position dépliée d'utilisation.According to the invention, each of the branches 5 of the main tube 3 is provided in its central part with a hinge 6 allowing the stretcher to fold back on itself, as shown in FIGS. 3 and 4. This hinge 6 is constituted here by a connecting rod 7 pivotally mounted on each branch portion by means of an axis 8. A locking means constituted by a female ring 9 slidingly mounted on one of the branch portions 5 and coming to be screwed on a male ring 10 fixed on the other branch portion, by enclosing the link 7, makes it possible to stiffen the frame 1 in its unfolded position of use.

L'armature métallique 1 est également pourvue à sa partie inférieure de deux tubes secondaires 11 de plus faible diamètre, reliés au tube principal 3 par des tubes de jonction 12 et qui s'étendent parallèlement à celui-ci le long des deux branches 5. Les extrémités de ces deux tubes 11sont relevées et soudées au tube principal 3, formant ainsi deux patins de luge. Bien entendu, les tubes 11 sont coupés au niveau des articulations à biellette 6, comme représenté en 13, afin de ne pas entraver le pliage de l'armature, mais forment néanmoins des patins continus facilitant l'introduction de la civière à l'intérieur de l'hélicoptère de sauvetage, en permettant au treuilliste de faire glisser la civière sur le bord de la porte cargo.The metal frame 1 is also provided at its lower part with two secondary tubes 11 of smaller diameter, connected to the main tube 3 by junction tubes 12 and which extend parallel to the latter along the two branches 5. The ends of these two tubes 11 are raised and welded to the main tube 3, thus forming two sledge runners. Of course, the tubes 11 are cut at the link joints 6, as shown in 13, so as not to impede the folding of the frame, but nevertheless form continuous pads facilitating the introduction of the stretcher inside from the rescue helicopter, allowing the winchman to slide the stretcher over the edge of the cargo door.

Les tubes 11 des patins de luge sont par ailleurs reliés ensemble par des tubes transversaux tels que 14 qui donnent à l'armature 1 sa rigidité latérale. Cette armature présente ainsi une certaine profondeur permettant d'accommoder la plaque de matériau composite 2 destinée à supporter le blessé.The tubes 11 of the sledge runners are also connected together by transverse tubes such as 14 which give the frame 1 its lateral rigidity. This frame thus has a certain depth making it possible to accommodate the plate of composite material 2 intended to support the injured person.

L'armature métallique 1 comprend également, du côté de la tête, un arceau 15 soudé au tube principal 3 et relié à la partie cintrée 4 de celui-ci par des tubes de jonction 16. Cet arceau est destiné à protéger la tête ou le casque du blessé lors de son transport sur la civière.The metal frame 1 also comprises, on the side of the head, a hoop 15 welded to the main tube 3 and connected to the curved part 4 thereof by junction tubes 16. This hoop is intended to protect the head or the helmet of the injured person during transport on the stretcher.

A l'autre extrémité de l'armature se trouve un cale-pied extensible 17, monté coulissant dans des fourreaux 18 soudés sur le bord intérieur des deux branches 5 du tube principal 3. Un moyen de verrouillage non représenté, constitué par exemple par des broches quart de tour, est en outre prévu pour bloquer ce cale-pied, soit dans sa position rétractée, soit dans sa position d'extension.At the other end of the frame is an extendable toe clip 17, slidably mounted in sheaths 18 welded to the inner edge of the two branches 5 of the main tube 3. A locking means not shown, constituted for example by quarter-turn pins, is further provided for locking this toe clip, either in its retracted position or in its extended position.

De petits tubes 19 et 20 sont également soudés sur les deux branches 5 du tube principal 3 de manière à faire saillie vers le haut, réalisant ainsi une protection latérale du blessé transporté au niveau des épaules et des tibias.Small tubes 19 and 20 are also welded to the two branches 5 of the main tube 3 so as to protrude upwards, thereby providing lateral protection for the injured person carried at the shoulders and shins.

Aux quatre extrémités de la civière et sur le tube principal 3 sont soudés des anneaux 21 pour la fixation d'élingues. Ces anneaux 21 sont disposés de telle sorte que lorsque la civière est hélitreuillée, la pantoire brélant la civière met celle-ci automatiquement dans une position inclinée sensiblement à 45°. Le blessé arrimé sur la plaque de matériau composite 2 conserve ainsi une position relativement stable.At the four ends of the stretcher and on the main tube 3 are welded rings 21 for fixing slings. These rings 21 are arranged in such a way that when the stretcher is helicopter-towed, the pantry brelating the stretcher automatically puts the stretcher in an inclined position substantially at 45 °. The injured person stowed on the composite material plate 2 thus retains a relatively stable position.

Enfin, l'armature métallique 1 est également équipée, à l'avant d'une paire de poignées extensibles 22, et à l'arrière d'une paire de poignées extensibles 23, ce qui permet, le cas échéant, de transformer la civière en brancard. Les poignées avant 22 sont montées coulissantes dans des fourreaux 24 soudés sur le bord inférieur du tube principal 3, tandis que les poignées arrière 23 sont montées coulissantes directement dans les extrémités des deux branches 5 de ce même tube principal.Finally, the metal frame 1 is also equipped, at the front with a pair of extendable handles 22, and at the rear with a pair of extendable handles 23, which makes it possible, if necessary, to transform the stretcher on a stretcher. The front handles 22 are slidably mounted in sleeves 24 welded to the lower edge of the main tube 3, while the rear handles 23 are slidably mounted directly in the ends of the two branches 5 of this same main tube.

Quant à la plaque de matériau composite 2, elle est réalisée en deux parties rigides 25 et 26, reliées l'une à l'autre par des articulations 27 disposées sur les côtés. Ces articulations sont constituées ici, comme on peut le voir plus clairement sur les figures 5 et 6, par une biellette 28 montée pivotante sur chacune des parties 25 et 26 de la plaque 2 au moyen d'un axe 29. La plaque 2 peut ainsi se replier sur elle-même selon un mouvement cinématique étudié, conjointement avec le repliement de l'armature 1, comme illustré sur les figures 3 et 4. Un moyen de blocage, constitué par un profilé en U 30 monté coulissant sur la partie de plaque 26, permet de rigidifier la plaque 2 dans sa position dépliée en venant en prise sur les bords contigus des deux parties de plaque 25 et 26, de part et d'autre de l'articulation 27.As for the plate of composite material 2, it is produced in two rigid parts 25 and 26, connected to each other by articulations 27 arranged on the sides. These joints are formed here, as can be seen more clearly in Figures 5 and 6, by a rod 28 pivotally mounted on each of the parts 25 and 26 of the plate 2 by means of an axis 29. The plate 2 can thus fold back on itself according to a kinematic movement studied, together with the folding of the frame 1, as illustrated in FIGS. 3 and 4. A locking means, constituted by a U-shaped section 30 slidably mounted on the plate part 26, makes it possible to stiffen the plate 2 in its unfolded position by engaging on the contiguous edges of the two plate parts 25 and 26, on either side of the articulation 27.

La plaque en matériau composite 2 épouse étroitement la forme du tube principal 3 de l'armature 1 sans faire saillie à l'extérieur et se trouve ainsi parfaitement protégée contre les chocs. Sa face supérieure est parfaitement plane, tandis que sa face inférieure présente à l'avant un renflement relativement important 31 qui se prolonge vers l'arrière par deux chevrons longitudinaux parallèles 32. Cette forme particulière, qui a fait l'objet d'une longue étude, permet à la civière, lorsqu'elle est jetée à l'eau, de se retourner automatiquement dans le bon sens et de prendre alors une position inclinée à environ 45°, l'extrémité supérieure de la civière se trouvant hors de l'eau sur environ 50 cm. Cette flottabilité à 45° est assurée lorsque la civière est équipée de tous ses accessoires nécessaires à l'hélitreuillage, c'est-à-dire une pantoire et un bout d'environ 50 mètres, le tout pesant environ 3 kg.The composite material plate 2 closely follows the shape of the main tube 3 of the frame 1 without protruding outside and is thus perfectly protected against shocks. Its upper face is perfectly flat, while its lower face has at the front a relatively large bulge 31 which is extended towards the rear by two parallel longitudinal rafters 32. This particular shape, which has been the subject of a long study, allows the stretcher, when thrown into the water, to automatically turn in the right direction and then take a position inclined at about 45 °, the upper end of the stretcher being out of the water about 50 cm. This buoyancy at 45 ° is ensured when the stretcher is equipped with all its accessories necessary for helicopter hoisting, that is to say a panty and a piece of approximately 50 meters, all weighing approximately 3 kg.

Selon une autre caractéristique de l'invention, la plaque de matériau composite 2 est fixée de manière amovible sur l'armature métallique 1. A cet effet, la partie avant de la plaque est pourvue d'un évidement venant en prise sur la partie cintrée 4 du tube principal 3, tandis que la partie arrière est pourvue de deux oreilles 33 percées d'un trou dans lequel vient en prise une broche quart de tour 34 supportée par l'armature.According to another characteristic of the invention, the plate of composite material 2 is removably fixed on the metal frame 1. For this purpose, the front part of the plate is provided with a recess engaging on the curved part 4 of the tube main 3, while the rear part is provided with two ears 33 pierced with a hole in which engages a quarter-turn spindle 34 supported by the frame.

Grâce à cette disposition, il est possible, une fois le blessé récupéré et ramené à terre, de déverrouiller rapidement la plaque 2 de l'armature 1 pour transporter le blessé sur la plaque 2 vers des moyens radiographiques appropriés. A cette fin, la plaque est équipée de sangles 35 permettant d'y arrimer directement le blessé, indépendamment de l'armature 1, ainsi que de quatre poignées de transport souples 36. De préférence, les sangles 35 seront pourvues d'un système d'attache rapide dont la partie femelle sera fixée à la plaque, permettant ainsi au sauveteur d'arrimer le blessé sur la plaque avec une seule main. De plus, le matériau composite constituant la plaque sera avantageusement prévu radiotransparent, ce qui permettra de radiographier le blessé sans avoir à le déplacer inutilement.Thanks to this arrangement, it is possible, once the injured person has been recovered and brought back to the ground, to quickly unlock the plate 2 of the frame 1 in order to transport the injured person on the plate 2 to appropriate radiographic means. To this end, the plate is equipped with straps 35 making it possible to directly secure the injured person there, independently of the frame 1, as well as four flexible carrying handles 36. Preferably, the straps 35 will be provided with a system of '' quick coupler, the female part of which will be fixed to the plate, allowing the rescuer to secure the injured person on the plate with one hand. In addition, the composite material constituting the plate will advantageously be provided radiolucent, which will make it possible to x-ray the injured person without having to move it unnecessarily.

On voit donc en définitive que la civière flottante selon l'invention présente de nombreux avantages par rapport à celles existant actuellement.It can therefore be seen ultimately that the floating stretcher according to the invention has many advantages compared to those currently existing.

Elle est tout d'abord pliante, grâce à ses articulations à biellettes 6 et 27, ce qui facilite considérablement son stockage, ainsi que son transport, éventuellement à dos d'homme. En position dépliée d'utilisation, elle présente néanmoins une très bonne rigidité, grâce à ses moyens de blocage 9-10 et 30.It is first of all folding, thanks to its articulations with links 6 and 27, which considerably facilitates its storage, as well as its transport, possibly on a man's back. In the unfolded position of use, it nevertheless has very good rigidity, thanks to its blocking means 9-10 and 30.

De plus, lorsqu'elle est jetée à l'eau, dans n'importe quelle position, elle se retourne dans le bon sens et retrouve en moins d'une minute sa position de flottaison inclinée à environ 45° qu'elle conserve ensuite en permanence quel que soit l'état de la mer. Ceci est dû à la forme particulière de la plaque de matériau composite 2 et permet, en cas de fractures ou de blessures graves à la colonne vertébrale, d'arrimer le blessé sur la civière dans la position exacte de flottaison qu'il occupe avec son gilet de sauvetage. Celui-ci est ensuite hissé jusqu'à l'hélicoptère de sauvetage dans la même position et à partir de cet instant, plus aucun mouvement ne sera nécessaire au blessé jusqu'aux moyens radiographiques de l'hôpital.In addition, when it is thrown into the water, in any position, it turns in the right direction and finds in less than a minute its float position tilted at about 45 ° which it then keeps in permanently whatever the state of the sea. This is due to the particular shape of the composite material plate 2 and allows, in the event of fractures or serious injuries to the spine, to secure the injured person on the stretcher in the exact flotation position he occupies with his life jacket. This one is then hoisted up to the rescue helicopter in the same position and from this moment, no more movement will be necessary for the injured person until the radiographic means of the hospital.

Une fois arrivé à terre, la civière se transforme éventuellement en brancard, grâce à ses poignées extensibles 22 et 23, puis la plaque de matériau composite 2, solidaire du blessé, est déverrouillée de l'armature 1 en escamotant simplement les deux broches quart de tour 34 prévues à cet effet. L'armature 1 peut alors être équipée d'une nouvelle plaque en vue d'un autre sauvetage, tandis que le blessé est acheminé dans les meilleures conditions vers un hôpital, toujours sur sa plaque de matériau composite, au moyen des poignées de transport 36, tout en étant fermement maintenu sur celle-ci par les sangles 35.Once on land, the stretcher eventually turns into a stretcher, thanks to its extendable handles 22 and 23, then the plate of composite material 2, secured to the injured person, is unlocked from the frame 1 by simply retracting the two quarter pins tower 34 provided for this purpose. Frame 1 can then be fitted with a new plate for another rescue, while the injured person is transported in the best conditions to a hospital, still on his plate of composite material, by means of the carrying handles 36, while being firmly held thereon by the straps 35.
