Abstract

The invention relates to the rig of single-masted light skiffs on which is threaded, with the aid of an attached sleeve, a triangular sail whose peak is connected to the end of a boom or of a wishbone. According to the invention, the sleeve (11) has a perimeter which is larger than that of the mast (13), and it is stretched by a filling lining (14) of synthetic foam. Such a rig is particularly suitable for a wind-surfing board. <IMAGE>

Description

L'invention concerne legréement des esquifs légers à mât unique et notamment des planches à voile.The invention relates to the approval of light skiffs with a single mast and in particular windsurfers.

Un telgréement comporte très généralement une voile triangulaire portée par le mât et dont l'empointure munie d'un oeillet, est fixée à l'extrémité soit d'une bôme classique longeant la bordure, soit, dans le cas d'une planche à voile, d'une bôme à deux branches appelée du nom anglaisde "wishbone", la voile passant alors entre les deux branches.Such an arrangement very generally comprises a triangular sail carried by the mast and the point of which provided with an eyelet, is fixed at the end either of a conventional boom along the edge, or, in the case of a windsurfing board , a boom with two branches called the English name "wishbone", the sail then passing between the two branches.

Parfois, la voile est complétée par une voile auxiliaire déflectrice en forme de triangle aplati dont les coins inférieur et supérieur sont reliés au pied et à la tête du mât, respectivement par une amure et par une drisse tandis que l'empointure porte un oeillet fixé à l'extrémité d'un support prolongeant la bôme ou le wishbone au-delà du point d'attache de ce dernier sur le mât.Sometimes the sail is completed by an auxiliary deflecting sail in the shape of a flattened triangle, the lower and upper corners of which are connected to the foot and the head of the mast, respectively by a tack and a halyard while the shank carries a fixed eyelet at the end of a support extending the boom or the boom beyond the point of attachment of the latter on the mast.

Le plus souvent la voile est enfilée sur le mât grâce à un fourreau rapporté formé par une bande de toile dont les deux zones marginales longitudinales sont appliquées et cousues respectivement sur les deux faces de la voile sur toute la hauteur du bord de cette dernière tourné vers le mât. Dans le cas d'une planche à voile, il serait plus exact de parler de deux fourreaux s'étendant le long du mât, respectivement de part et d' aitre d'une échancrure située au niveau du point d'attache du wishbone sur le mât, toutefois dans tout ce qui suit le vocable fourreau désignera indifféremment un fourreau sans solution de continuité ou un fourreau en deux parties.Most often the sail is threaded on the mast thanks to an attached sheath formed by a strip of canvas whose two longitudinal marginal zones are applied and sewn respectively on the two faces of the sail over the entire height of the edge of the latter turned towards the mast. In the case of a windsurfing board, it would be more accurate to speak of two sleeves extending along the mast, respectively on the side and at the top of a notch located at the point of attachment of the wishbone on the mast, however in all that follows the term sheath will designate either a sheath without a continuity solution or a sheath in two parts.

Un premier objet de l'invention est de prévoir que le fourreau a un périmètre intérieur nettement plus grand que le périmètre exté-.. rieur du mât et qu'il est tendu par une garniture de remplissage en mousse semi-souple de matière synthétique à cellules fermées présentant une section en coin effilé qui, à l'opposé de la pointe épouse le profil du mât.A first object of the invention is to provide that the sheath has an inside perimeter significantly larger than the outside perimeter of the mast and that it is stretched by a filling filling made of semi-flexible foam of synthetic material to closed cells with a tapered corner section which, opposite the point, follows the profile of the mast.

Afin de faciliter le transport et le garage de l'esquif, il est. fréquent d'utiliser un mât tubulaire en plusieurs tronçons emboîtés, démontables ou télescopiques. Pour permettre à l'utilisateur de choisir le degré de souplesse du mât, il est alors avantageux de prévoir que le tronçon tubulaire supérieur qui s'étend sur sensiblement la moitié de la hauteur du mât, peut être emboîté dans une embase constituée au gré de l'utilisateur, par un tronçon de tube unique de plus grande section ou par l'assemblage par emboîtement de deux tronçons de tube ayant sensiblement la même longueur, le tronçon inférieur ayant une section plus petite pour être emboîtée à l'intérieur de l' autre qui forme alors le tronçon central et la partie la plus rigide du mât. La plus grande souplesse du tronçon inférieur par rapport à celle du tronçon médian permet d'améliorer la "défense" sur coup de vent.In order to facilitate the transport and the garage of the skiff, it is. frequent to use a tubular mast in several nested, removable or telescopic sections. To allow the user to choose the degree of flexibility of the mast, it is then advantageous to provide that the upper tubular section which extends over substantially half the height of the mast, can be fitted into a base cons formed at the user's discretion, by a single section of tube of larger section or by the interlocking assembly of two sections of tube having substantially the same length, the lower section having a smaller section to be fitted to the inside the other which then forms the central section and the most rigid part of the mast. The greater flexibility of the lower section compared to that of the middle section makes it possible to improve the "defense" in gale.

De préférence, les tronçons tubulaires présentent une section ovale dont le grand axe est situé dans le plan de la voile. Eventuel- lement, l'un au moins des tronçons est renforcé par une cloison intérieure médiane perpendiculaire au grand axe ou par enfoncement à frottement doux, au niveau de l'effort maximal, d'un tube de renfort rond.Preferably, the tubular sections have an oval section whose major axis is located in the plane of the sail. Optionally, at least one of the sections is reinforced by a median internal partition perpendicular to the major axis or by a soft friction drive, at the level of the maximum force, of a round reinforcing tube.

Lorsque la voile présente du côté du mât un "rond de bord", c' est-à-dire lorsque le fourreau s'étend en arc de cercle avec une convexité tournée vers le mât, un autre objet de l'invention prévoit que le mât est pré-cambré pour présenter une courbure de même sens que celle du fourreau mais de rayon plus grand que celui de cette dernière. Ainsi on diminue l'effort exercé sur les angles haut et bas de la voile lors de l'étarquage de l'amure de l'empointure, ce qui permet un allégement des renforts classiques par surépaisseur.When the sail has a "round edge" on the side of the mast, that is to say when the sheath extends in an arc of a circle with a convexity facing the mast, another object of the invention provides that the mast is pre-arched to present a curvature in the same direction as that of the sleeve but with a radius greater than that of the latter. Thus, the force exerted on the top and bottom angles of the sail is reduced during the stretching of the tack of the wedge, which allows a reduction of the conventional reinforcements by extra thickness.

Si le gréement comporte une voile auxiliaire déflectrice dont l'empointure est alors fixée sur l'extrémité d'un support rigide prolongeant la bôme ou le whisbone, un autre objet de l'invention est de prévoir que ce support est constitué par une tringle pliée en forme de M à jambages allongés, la pointe centrale rentrante étant destinée à recevoir l'oeillet de l'empointure de la voile déflectrice et les deux jambages pouvant être écartés élastiquement et présentant leurs extrémités libres coudées vers l'intérieur pour coopérer respectivement avec deux emplantures ou deux trous ménagés sur la bôme ou le wishbone de part et d'autre de son point d'attache sur le mât. Ce montage permet le débattement de la voile auxiliaire de l'un à l'autre des jambages du M, organisant ainsi au voisinage du mât, entre cette voile auxiliaire et le fourreau de la voile principale, quelle que soit la force "prise" par le vent, un "effet de fente" qui empêche le décollement des filets d'air de l'extrados de la voile principale, ce qui favorise l'écoulement du vent relatif lors des bords grand largue.If the rigging comprises an auxiliary deflecting sail, the point of which is then fixed on the end of a rigid support extending the boom or the whiskey, another object of the invention is to provide that this support consists of a folded rod M-shaped with elongated legs, the re-entrant central point being intended to receive the eyelet of the point of the deflecting sail and the two legs which can be elastically separated and having their free ends bent inwardly to cooperate respectively with two footings or two holes made on the boom or the boom on either side of its point of attachment to the mast. This assembly allows the displacement of the auxiliary sail from one to the other of the legs of the M, thus organizing in the vicinity of the mast, between this auxiliary sail and the sheath of the main sail, whatever the force "taken" by the wind, a "split effect" which prevents the detachment of the air streams from the upper surface of the main sail, which favors the flow of the relative wind during the large drop edges.

L'invention sera mieux comprise à la lecture de la description qui va suivre et à l'examen des dessins annexés représentant, à titre d'exemple non limitatif, certains modes de réalisation de l'invention et dans lesquels :

  • - la figure 1 montre en élévation une voile d'esquif léger avec un fourreau selon l'invention, le mât devant recevoir cette voile et la garniture de remplissage du fourreau étant représentée à côté,
  • - la figure 2 est une coupe du fourreau enfilé sur le mât,
  • - la figure 3 montre, schématiquement, les deux montages possibles d'un mât selon l'invention,
  • - la figure 4 est une élévation d'un gréement avec voile déflectrice,
  • - la figure 5 est une vue de dessus du gréement de la figure 4,
  • - les figures 6 et 7 montrent le verrouillage d'un mât de planche à voile sur son pied.
The invention will be better understood on reading the description which follows and on examining the appended drawings showing, by way of nonlimiting example, certain embodiments of the invention and in which:
  • FIG. 1 shows in elevation a light skiff sail with a sheath according to the invention, the mast having to receive this sail and the filling filling of the sheath being shown alongside,
  • FIG. 2 is a section of the sheath threaded on the mast,
  • FIG. 3 schematically shows the two possible assemblies of a mast according to the invention,
  • FIG. 4 is an elevation of a rigging with a deflecting veil,
  • FIG. 5 is a top view of the rigging of FIG. 4,
  • - Figures 6 and 7 show the locking of a windsurf mast on its foot.

Sur les figures 1 et 2, une voile 10 triangulaire est munie le Long de son bord de mât d'un fourreau 11 formé par une bande oblongue iont les zones marginales longitudinales sont appliquées et cousues sur les deux faces respectivement dudit bord. En fait, ici, la voile est destinée à une planche à voile et le fourreau 11 est en deux par- :ies s'étendant de part et d'autre d'une échancrure 12 située au ni- veau du point d'attache du wishbone de la planche sur le mât.In FIGS. 1 and 2, a triangular sail 10 is provided along its mast edge with a sheath 11 formed by an oblong strip, and the longitudinal marginal zones are applied and sewn on the two faces respectively of said edge. In fact, here, the sail is intended for a windsurfing board and the sheath 11 is in two parts: ies extending on either side of a notch 12 situated at the level of the attachment point of the board boom on the mast.

Le périmètre intérieur du fourreau 11 est nettement plus grand que le périmètre extérieur du mât 13 sur lequel il doit être enfilé et les parois du fourreau sont tendues par une garniture de remplissage 14 en mousse synthétique à cellules fermées ayant une section en coin à pointe 15 effilée. Afin de faciliter son introduction, cette garniture est sectionnée en tronçons, quatre dans l'exemple représenté. Cette disposition améliore l'aérodynamisme de la voile et, en outre, rend le mât insubmersible, ce qui facilite son relevage lorsqu'il a été couché accidentellement sur le plan d'eau et interdit le retournement dans le cas d'un catamaran par exemple.The internal perimeter of the sleeve 11 is significantly larger than the external perimeter of the mast 13 on which it is to be threaded and the walls of the sleeve are stretched by a filling pad 14 of closed cell synthetic foam having a wedge-shaped section with a point 15 tapered. In order to facilitate its introduction, this trim is sectioned into sections, four in the example shown. This arrangement improves the aerodynamics of the sail and, moreover, makes the mast unsinkable, which makes it easier to lift when it has been accidentally laid down on the water and prevents overturning in the case of a catamaran for example. .

Il est à noter que la largeur du fourreau n'est pas limitée, que ce dernier peut être très important et, qu'à la limite, on peut concevoir une voile à double épaisseur entièrement matelassée par une garniture en mousse synthétique à condition évidemment, de donner des formes convenables à chaque tronçon de la garniture et de prévoir un soufflet au niveau de l'échancrure 12 dans le cas d'une planche àvoile.It should be noted that the width of the scabbard is not limited, that the latter can be very large and that, at the limit, it is possible to design a double-thickness sail entirely quilted with a synthetic foam lining provided, of course, to give suitable shapes to each section of the lining and to provide a bellows at the notch 12 in the case of a sailboard.

A la figure 1 le mât 13 est constitué de façon connue par des tronçons tubulaires emboîtés, à savoir un tronçon supérieur 13a qui s'étend sur sensiblement la moitié de la hauteur totale du mât et un tronçon inférieur 13b. Afin de permettre d'adapter la souplesse du mât aux conditions d'utilisation, il est possible de mettre à la disposition de l'utilisateur soit une embase formée par un tronçon unique 13b, soit une embase formée par l'emboîtement de deux tronçons 13c, 13d (figure 3) ayant sensiblement la même longueur. Cependant, pour améliorer la défense sur coup de vent, notamment dans le cas d'une planche à voile, c'est la partie inférieure du mât, sous le wishbone, qui doit présenter une bonne souplesse et, selon l'invention, c'est le tronçon médian 13c qui a le-plus grand diamètre et constitue la partie la plus rigide, les tronçons 13a et 13d venant s'embotter respectivement aux deux extrémités de ce tronçon 13c.In Figure 1 the mast 13 is constituted in a known manner by nested tubular sections, namely an upper section 13a which extends over substantially half of the total height of the mast and a lower section 13b. In order to adapt the flexibility of the mast to the conditions of use, it is possible to provide the user with either a base formed by a single section 13b, or a base formed by the interlocking of two sections 13c , 13d (Figure 3) having substantially the same length. However, to improve the defense against gale, in particular in the case of a windsurfing board, it is the lower part of the mast, under the boom, which must have good flexibility and, according to the invention, it is the middle section 13c which has the largest diameter and constitutes the most rigid part, the sections 13a and 13d coming to nest respectively at the two ends of this section 13c.

De préférence, la section des tronçons tubulaires constituant le mât, est un ovale dont le grand axe est sensiblement dans le plan de la voile (figure 2). Dans ce cas, à un ou plusieurs niveaux, notamment au niveau de l'effort maximal (sensiblement le niveau du point vélique), il est possible de prévoir un renforcement, soit par une cloison intérieure médiane 16 perpendiculaire au grand axe (représentée en traits mixtes à la figure 2), soit en introduisant à frottement doux un ou plusieurs tronçons de tube rond.Preferably, the section of the tubular sections constituting the mast is an oval whose major axis is substantially in the plane of the sail (Figure 2). In this case, at one or more levels, in particular at the level of the maximum force (substantially the level of the vélique point), it is possible to provide a reinforcement, either by a median internal partition 16 perpendicular to the major axis (shown in lines mixed in Figure 2), either by gently introducing one or more sections of round tube.

Lorsque la voile 10 présente du côté du mât 13 un rond de bord, c'est-à-dire lorsque le fourreau 11 s'étend en arc de cercle, le mât 13 peut être pré-cambré, comme cela est représenté aux figures 1 et 3. Toutefois, la cambrure du mât au repos doit avoir un rayon de courbure un peu supérieur à celui du fourreau. Cette pré-cambrure diminue l'effort exercé sur les angles de la voile lorsqu'on étarque l'amure 25 (figure 5) d'empointure, ce qui permet d'alléger les renforts classiques par surépaisseurs et diminuerle plissage de la voile.When the sail 10 has an edge circle on the side of the mast 13, that is to say when the sheath 11 extends in an arc, the mast 13 can be pre-bent, as shown in FIGS. 1 and 3. However, the camber of the mast at rest must have a radius of curvature slightly greater than that of the scabbard. This pre-arch decreases the force exerted on the angles of the sail when the tack tack 25 (FIG. 5) is stretched, which makes it possible to lighten the conventional reinforcements by extra thicknesses and reduce the pleating of the sail.

Comme il a été dit ci-avant, la voile 10 enfilée sur le mât est parfois associée à une voile auxiliaire déflectrice 17 (figure 4 et 5) en forme de triangle aplati dont les coins inférieur et supérieur sont reliés au pied et à la tête-du mât, respectivement par une amure 18 et une drisse 19, tandis que l'empointure porte un oeillet 20 fixé à l'- extrémité d'un support 21 prolongeant la bôme ou le wishbone au-delà du point d'attache de ce dernier sur le mât. Un tel gréement est représenté aux figures 4 et 5 sur une planche à voile 22, avec de façon classique un pied de mât 23 et un wishbone 24. Comme dans cet exemple il s'agit d'une planche à voile, l'utilisateur doit pouvoir passer de babord à tribord ou inversement sans lâcher le wishbone et le support 21 doit être relativement court (environ 35 à 40 cm) pour que son extrémité passe devant la poitrine de l'utilisateur lorsque ce dernier tient, avec ses bras allongés devant lui., les deux branches du wishbone, mais lorsqu'il s'agit de tout autre esquif léger, la longueur du support peut être quelconque. Comme cela est bien visible à la figure 5, le support 21 a la forme générale d'un M à jambages allongés. L'angle rentrant du M est destiné à recevoir l'oeillet 20 de la voile auxiliaire et les jambages peuvent être écartés élastiquement pour amener leurs extrémités libres, coudées vers l'intérieur, à s'engager dans des trous ou des emplantures prévues en 26a, 26b sur l'embout 27 de fixation du wishbone 24 sur le mât 13. Cette disposition permet le débattement de la voile auxiliaire d'un jambage à l'autre du M, ce qui organise en 29 entre la voile auxiliaire 17 et le fourreau 11 un effet de fente empêchant le décollement des filets d'air de l'extrados de la voile 10.As mentioned above, the sail 10 threaded on the mast is sometimes associated with an auxiliary deflecting sail 17 (FIGS. 4 and 5) in the shape of a flattened triangle, the lower and upper corners of which are connected to the foot and to the head. -from the mast, respectively by a tack 18 and a halyard 19, while the recess carries an eyelet 20 fixed to the end of a support 21 extending the boom or the boom beyond the point of attachment of this last on the mast. Such rigging is represented felt in FIGS. 4 and 5 on a windsurf board 22, conventionally with a mast foot 23 and a wishbone 24. As in this example it is a windsurf board, the user must be able to pass from port side to starboard or vice versa without letting go of the wishbone and the support 21 must be relatively short (about 35 to 40 cm) so that its end passes in front of the user's chest when the latter holds, with his arms extended in front of him., both branches of the wishbone, but when it comes to any other light skiff, the length of the support can be arbitrary. As is clearly visible in Figure 5, the support 21 has the general shape of an M with elongated legs. The re-entrant angle of the M is intended to receive the eyelet 20 of the auxiliary sail and the legs can be spaced apart elastically so as to bring their free ends, bent inward, to engage in holes or in the recesses provided for in 26a , 26b on the nozzle 27 for fixing the wishbone 24 on the mast 13. This arrangement allows the travel of the auxiliary sail from one leg to the other of the M, which organizes at 29 between the auxiliary sail 17 and the sheath 11 a slitting effect preventing the detachment of the air streams from the upper surface of the sail 10.

Lorsque le gréement équipe une planche à voile, il est avantageux de prévoir un moyen d'amarrage permettant une séparation aisée et rapide du mât par rapport à son pied et de la voile par rapport au mât. C'est pourquoi l'invention prévoit un emboîtement à frottement doux du mât sur le touret du pied de mât et un verrouillage par agrafage élastique, l'agrafe élastique étant constituée par un étrier dont les extrémités des branches, recourbées vers l'intérieur, viennent s'engager chacune dans deux perforations radiales conjuguées du mât et du touret et dont la partie transversale comporte une boucle utilisée comme point d'attache de l'amure étarquant la voile. Un tel moyen de verrouillage du mât d'une planche à voile est représenté aux figures 6 et 7.When the rigging equips a windsurfing board, it is advantageous to provide a mooring means allowing an easy and rapid separation of the mast relative to its foot and of the sail relative to the mast. This is why the invention provides for a soft friction fitting of the mast on the mast foot drum and a locking by elastic stapling, the elastic staple being constituted by a stirrup, the ends of the branches of which are curved inwards, each engage in two combined radial perforations of the mast and the reel, the transverse part of which comprises a loop used as the attachment point for the tack stretching the sail. Such a means for locking the mast of a windsurfing board is shown in FIGS. 6 and 7.

A la figure 6, un pied de mât traditionnel comporte une articulation 30 en caoutchouc moulé ayant la forme d'un hyperboloide de révolution limité par deux sections droites dans chacune desquelles est noyée une platine métallique affleurante 31, respectivement 32, portant un axe central fileté 33, respectivement 34, en saillie vers 1' extérieur. L'axe 34 de la platine inférieure 32 est vissé ou autrement fixé dans une embase 35 (représentée schématiquement en traits interrompus) qui s'emboîte et est immobilisée fermement par un moyen convenable dans un puits 36 ménagé dans une planche à voile 37.In FIG. 6, a traditional mast foot has an articulation 30 of molded rubber having the shape of a hyperboloid of revolution limited by two straight sections in each of which is embedded a flush metal plate 31, respectively 32, carrying a central threaded axis 33, respectively 34, projecting outwards. The axis 34 of the bottom plate 32 is screwed or the like ment fixed in a base 35 (shown schematically in broken lines) which fits and is immobilized firmly by a suitable means in a well 36 formed in a windsurfing board 37.

Sur l'axe 33 de la platine supérieure 31, est vissée une pièce intermédiaire 38 en matière synthétique moulée qui comporte un socle 38a surmonté en son centre d'une partie cylindrique oblongue 38b. Le diamètre du socle 38a est sensiblement égal à celui de la platine 31. Sur la partie 38b est monté, libre en rotation, un touret 39 en matière synthétique qui est muni à sa partie inférieure d'une collerette débordante 40 et est retenu en position longitudinale par une broche 41 traversant diamétralement la partie 38b juste au-dessus de sa face supérieure.On the axis 33 of the upper plate 31, is screwed an intermediate piece 38 of molded synthetic material which comprises a base 38a surmounted in its center by an oblong cylindrical part 38b. The diameter of the base 38a is substantially equal to that of the plate 31. On the part 38b is mounted, free in rotation, a drum 39 made of synthetic material which is provided at its lower part with an overflowing flange 40 and is retained in position longitudinal by a pin 41 diametrically crossing the part 38b just above its upper face.

Sur le touret 39 est emboîtée à frottement doux la partie inférieure d'un mât tubulaire 50. Selon l'invention, le verrouillage du mât 50 sur le touret 39 est obtenu par agrafage. L'agrafe (figures 1 et 2) est constituée par un étrier 42 dont les branches 43 et 44 peuvent s'écarter élastiquement l'une de l'autre et dont les extrémités libres 43a et 44a sont recourbées à angle droit vers l'intérieur pour coopérer avec des perforations conjuguées 45a, 46a, respectivement 45b, 46b, ménagées respectivement à travers les parois du mât 50 (perforations 45a, 45b) et les parois du touret 39 (perforations 46a, 46b).On the reel 39 is fitted with soft friction the lower part of a tubular mast 50. According to the invention, the locking of the mast 50 on the reel 39 is obtained by stapling. The clip (FIGS. 1 and 2) is constituted by a stirrup 42 whose branches 43 and 44 can deviate elastically from one another and whose free ends 43a and 44a are bent at right angles inwards to cooperate with conjugated perforations 45a, 46a, respectively 45b, 46b, formed respectively through the walls of the mast 50 (perforations 45a, 45b) and the walls of the drum 39 (perforations 46a, 46b).

L'étrier 42 (figure 2) comporte sur sa partie transversale une boucle 48. Cette boucle 48 accroît l'élasticité lors de l'écartement des branches 43 et 44. En outre, la boucle 48 constitue un point d' amarrage pour l'amure (non représentée) utilisée pour étarquer la voile.The stirrup 42 (Figure 2) has on its transverse part a loop 48. This loop 48 increases the elasticity when the branches 43 and 44 are separated. In addition, the loop 48 constitutes a mooring point for the tack (not shown) used to tow the sail.

Avec une telle disposition l'arrachement de l'étrier 42 permet de séparer le mât de son pied et de faire glisser le fourreau de la voile le long du mât sans avoir aucun noeud ou autre attache à défaire. Dans le cas où la voile a été couchée accidentellement sur le plan d'eau et que la force du vent interdit son relevage, l'arrachement de l'étrier 42 entraîne la séparation du gréement de la planche, le mât se dégage pratiquement seul du fourreau par gravité et coule, et le "véliplanchiste" dispose alors de la voile qui, si elle comporte une garniture en mousse comme il est dit ci-avant, peut jouer le rôle d' une bouée de. sauvetage.With such an arrangement, the tearing off of the stirrup 42 makes it possible to separate the mast from its foot and to slide the sheath of the sail along the mast without having any knot or other attachment to undo. In the event that the sail has been accidentally laid down on the water and the force of the wind prohibits its lifting, the tearing of the stirrup 42 results in the separation of the rigging from the board, the mast is released practically alone from the scabbard by gravity and sinks, and the "windsurfer" then has the sail which, if it has a foam lining as it is said above, can play the role of a buoy. rescue.

Des modifications peuvent être apportées aux réalisations décrites et représentées, sans pour cela sortir du cadre de l'invention. C'est ainsi, par exemple, que la voile 10 (figure 1) peut présenter un rond de bord le long de la chute 28 et être alors lattée.Changes can be made to the achievements of written and represented, without departing from the scope of the invention. Thus, for example, the sail 10 (Figure 1) can have an edge circle along the fall 28 and then be battened.
