Description

Dispositif de freinage pour la bôme d'un voilier Braking device for the boom of a sailboat
L'invention concerne un dispositif de freinage pour la bôme d'un voilier.The invention relates to a braking device for the boom of a sailboat.
Un tel dispositif est particulièrement utile lors d'une manœuvre d'empannage. Cette dernière se pratique lorsqu'un voilier navigue au vent arrière, lorsque la bôme est débordée à l'extérieur du voilier. La manœuvre d'empannage consiste à changer, de manière volontaire ou involontaire, le cap du voilier pour lui faire franchir le lit du vent par l'arrière.Such a device is particularly useful during a jibing maneuver. The latter is practiced when a sailboat sails in the downwind, when the boom is overflowed outside the sailboat. The jibing maneuver is to change, voluntarily or involuntarily, the heading of the boat to make it cross the wind bed from behind.
A cette occasion, si cette manœuvre n'est pas ou mal contrôlée, la bôme passe violemment d'un bord à l'autre en prenant très rapidement de la vitesse, et ce d'autant plus que le vent est fort et que la mer est agitée. La bôme peut alors heurter le haubanage et conduire à la rupture de la bôme ou du vit du mulet qui est l'articulation de la bôme sur le mat.On this occasion, if this maneuver is not or poorly controlled, the boom passes violently from one side to the other taking very quickly speed, and especially as the wind is strong and the sea is agitated. The boom can then hit the guying and lead to the rupture of the boom or the mule's life which is the articulation of the boom on the mast.
Il est également possible qu'un membre de l'équipage séjournant sur le pont puisse être surpris par la vitesse de déplacement de la bôme, ce qui occasionne souvent des blessures très graves, en particulier à la tête.It is also possible that a member of the crew staying on the bridge may be surprised by the speed of movement of the boom, which often causes very serious injuries, especially to the head.
Afin de sécuriser la manœuvre d'empannage, il est connu d'utiliser des dispositifs de freinage de la bôme permettant de diminuer sa vitesse de déplacement. Un cordage principal est alors fixé ou guidé au niveau de ses extrémités sur chacun des bords du voilier, par exemple aux cadènes de bas hauban. Le cordage passe par le dispositif de freinage, ce dernier étant fixé sous la bôme.In order to secure the jibing maneuver, it is known to use braking devices of the boom to reduce its speed of movement. A main rope is then fixed or guided at its ends on each of the edges of the sailboat, for example to the lower shrouds. The rope passes through the braking device, the latter being fixed under the boom.
Des dispositifs de ce type sont connus des documents EP 0 630 806, US 4 941 420, GB 2 299 798, US 4 138 962 et GB 2 358 847.Devices of this type are known from EP 0 630 806, US 4 941 420, GB 2 299 798, US 4 138 962 and GB 2 358 847.
Ces dispositifs comportent un corps équipé de moyens de fixation, notamment à la bôme ou à un cordage de commande, et de moyens de freinage d'un cordage principal dont les extrémités sont fixées ou guidées en deux points disposés de part et d'autre de l'axe médian longitudinal du voilier. Ces dispositifs sont généralement complexes, constitués de plusieurs pièces, encombrants et onéreux. En outre, ils nécessitent pour leur mise en oeuvre de faire passer une extrémité du cordage dans le dispositif de freinage. Ils ne peuvent par conséquent pas être installés directement en milieu du cordage. La mise en oeuvre de tels dispositifs est donc longue et fastidieuse. L'invention vise à remédier à ces inconvénients en proposant un dispositif de freinage peu coûteux, léger, de dimensions réduites et facile à installer.These devices comprise a body equipped with fastening means, in particular at the boom or a control rope, and braking means of a main rope whose ends are fixed or guided in two points arranged on either side of the longitudinal center line of the sailboat. These devices are generally complex, consisting of several pieces, bulky and expensive. In addition, they require for their implementation to pass one end of the rope in the braking device. They can not therefore be installed directly in the middle of the rope. The implementation of such devices is therefore long and tedious. The invention aims to overcome these disadvantages by providing an inexpensive braking device, lightweight, small in size and easy to install.
A cet effet, l'invention concerne un dispositif de freinage du type précité, caractérisé en ce que les moyens de freinage comportent au moins une première ouverture de passage d'une boucle du cordage principal, ménagée dans le corps et une seconde ouverture ménagée dans le corps, sensiblement parallèle à la première ouverture et à l'intérieur de laquelle fait saillie un élément destiné à retenir la boucle par passage de celle-ci autour de lui.To this end, the invention relates to a braking device of the aforementioned type, characterized in that the braking means comprise at least a first passage opening of a loop of the main rope, formed in the body and a second opening in the body, substantially parallel to the first opening and inside which protrudes an element for retaining the loop by passing it around it.
L'utilisateur passe ainsi simplement une boucle formée sur le cordage principal, l'insère dans l'ouverture de passage puis passe la boucle autour de l'élément en saillie.The user simply passes a loop formed on the main rope, inserts it into the passage opening and then passes the loop around the projecting element.
Le frottement du cordage sur le corps est augmenté du fait des différentes courbures du cordage et de la tension exercée sur celui-ci.The friction of the rope on the body is increased because of the different bends of the rope and the tension exerted on it.
Selon une caractéristique de l'invention, l'élément en saillie est constitué par un doigt faisant saillie vers l'intérieur de la seconde ouverture, du côté opposé à la première ouverture, la longueur de l'élément en saillie étant inférieure à la longueur de la seconde ouverture selon l'axe de l'élément. Avantageusement, le corps comporte au moins deux ouvertures de passage de la boucle du cordage principal, sensiblement parallèles entre elles.According to a feature of the invention, the projecting element is constituted by a finger projecting towards the inside of the second opening, on the opposite side to the first opening, the length of the projecting element being less than the length. the second opening along the axis of the element. Advantageously, the body comprises at least two passage openings of the loop of the main rope, substantially parallel to each other.
La puissance de freinage est d'autant plus importante que le nombre et la surface des zones de courbure du cordage sont importants. Par conséquent, le passage du cordage dans une pluralité d'ouvertures permet d'augmenter la puissance de freinage du dispositif.The braking power is all the more important as the number and the surface of the bending zones of the rope are important. Therefore, the passage of the rope in a plurality of openings increases the braking power of the device.
Préférentiellement, le corps comporte trois ouvertures de passage de la boucle du cordage principal.Preferably, the body has three openings for passage of the loop of the main rope.
Selon une caractéristique de l'invention, le corps est de forme allongée et plate, les ouvertures de passage de la boucle du cordage principal étant décalées les unes par rapport aux autres selon l'axe médian longitudinal du corps et centrées sur cet axe.According to one characteristic of the invention, the body is elongated and flat, the passage openings of the loop of the main rope being offset relative to each other along the longitudinal median axis of the body and centered on this axis.
Selon une possibilité de l'invention, l'ouverture de passage est de forme oblongue, l'axe défini par l'ouverture étant sensiblement perpendiculaire à l'axe médian longitudinal du corps. Avantageusement, les moyens de fixation sont disposés à une extrémité du corps et centrés sur l'axe médian longitudinal de celui-ci. Préférentiellement, la seconde ouverture est située du côté de l'extrémité du corps comportant les moyens de fixation.According to a possibility of the invention, the passage opening is of oblong shape, the axis defined by the opening being substantially perpendicular to the longitudinal median axis of the body. Advantageously, the fastening means are disposed at one end of the body and centered on the longitudinal central axis thereof. Preferably, the second opening is located on the side of the end of the body having the fastening means.
L'invention concerne en outre un procédé d'utilisation du dispositif de freinage selon l'invention, caractérisé en ce qu'il comporte les étapes suivantes :The invention further relates to a method of using the braking device according to the invention, characterized in that it comprises the following steps:
- une première étape de formation d'une boucle avec le cordage principal,a first step of forming a loop with the main rope,
- une seconde étape de passage de la boucle dans au moins une ouverture de passage du corps, - une troisième étape de passage de la boucle issue de l'ouverture de passage autour de l'élément en saillie.a second step of passage of the loop in at least one passage opening of the body; a third step of passage of the loop issuing from the passage opening around the projecting element.
Selon une possibilité de l'invention, entre la seconde et la troisième étape, la boucle issue de l'ouverture de passage est passée dans la seconde ouverture puis à nouveau dans l'ouverture de passage. La boucle est alors enroulée autour de la zone du corps située entre l'ouverture de passage et la seconde ouverture, de manière à augmenter par frottement la puissance de freinage.According to a possibility of the invention, between the second and the third step, the loop resulting from the passage opening is passed in the second opening and then again in the passage opening. The loop is then wrapped around the area of the body located between the passage opening and the second opening, so as to increase by friction the braking power.
De toute façon, l'invention sera bien comprise à l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exemple non limitatif, une forme d'exécution de ce dispositif de freinage.In any case, the invention will be better understood with the aid of the description which follows, with reference to the appended schematic drawing showing, by way of non-limiting example, an embodiment of this braking device.
Figures 1 et 2 représentent un voilier équipé du dispositif de freinage selon l'invention, respectivement selon une première et une seconde formes de mise œuvre ; Figure 3 à 5 représentent les étapes successives d'un premier montage du cordage principal sur le dispositif de freinage ;Figures 1 and 2 show a sailboat equipped with the braking device according to the invention, respectively according to a first and a second implementation forms; Figures 3 to 5 show the successive steps of a first assembly of the main rope on the braking device;
Figure 6 à 8 représentent des variantes de montage du cordage principal ;Figure 6-8 show mounting variants of the main rope;
Les figures 1 et 2 représentent un voilier comportant un mat 1 équipé d'une borne 2 et d'une voile 3.FIGS. 1 and 2 show a sailboat comprising a mast 1 equipped with a terminal 2 and a sail 3.
Un dispositif de freinage 4, également appelé frein de borne est disposé sous la bôme 2 et fixé à celle-ci par l'intermédiaire d'une manille 5.A braking device 4, also called a terminal brake, is arranged under the boom 2 and fixed thereto by means of a shackle 5.
Selon une première mise en œuvre du dispositif de freinage 4 représentée en figure 1 , un cordage principal 6 est monté sur le dispositif de freinage 4, les deux extrémités du cordage principal étant amenées au cockpit par l'intermédiaire de poulies de renvoi 8 fixées sur chaque bord du voilier aux cadènes de bas hauban.According to a first implementation of the braking device 4 shown in FIG. 1, a main rope 6 is mounted on the braking device 4, the two ends of the main rope being brought to the cockpit by means of return pulleys 8 fixed on each edge of the sailboat to the bottom of the shrouds.
La tension du cordage peut alors être réglée au niveau du cockpit.The tension of the rope can then be adjusted at the level of the cockpit.
Selon une autre possibilité de mise en œuvre représentée en figure 2, les extrémités du cordage principal 6 sont directement fixées aux cadènes de bas hauban. Le dispositif de freinage 4 est relié à une première extrémité d'un cordage de commande 10 sur lequel une tension peut être réglée de manière prédéfinie. La seconde extrémité du cordage de commande est amenée au cockpit par l'intermédiaire de poulies de renvoi 11. La tension exercée sur le dispositif de freinage 4 influe alors sur la tension du cordage principal 6 et, par conséquent, sur la puissance de freinage.According to another implementation possibility shown in FIG. 2, the ends of the main rope 6 are directly attached to the lower shrouds. The braking device 4 is connected to a first end of a control rope 10 on which a voltage can be set in a predefined manner. The second end of the control rope is brought to the cockpit by means of return pulleys 11. The tension exerted on the braking device 4 then influences the tension of the main rope 6 and, consequently, the braking power.
Comme cela apparaît notamment en figure 3, le dispositif de freinage 4 comporte un corps 12 réalisé en matériau métallique et forgé en une seule pièce. Le corps 12 est de forme allongée et plate, la manille de fixation 5 étant disposée au niveau d'une première extrémité 13 du corps 12.As appears in particular in Figure 3, the braking device 4 comprises a body 12 made of metal material and forged in one piece. The body 12 is of elongate and flat shape, the fixing shackle 5 being disposed at a first end 13 of the body 12.
Le corps comporte des première 14, deuxième 15 et troisième 16 ouvertures de passage oblongues, décalées les unes par rapport aux autres suivant l'axe médian longitudinal A du corps 12, respectivement de la première extrémité 13 vers la deuxième extrémité 17 du corps 12, et centrées sur l'axe A.The body comprises first 14, second 15 and third 16 oblong passage openings, offset relative to each other along the longitudinal median axis A of the body 12, respectively from the first end 13 to the second end 17 of the body 12, and centered on the axis A.
L'axe défini par chacune des ouvertures de passage 14, 15, 16 est disposé sensiblement perpendiculairement à l'axe du corps A.The axis defined by each of the passage openings 14, 15, 16 is disposed substantially perpendicular to the axis of the body A.
Le corps comporte en outre une ouverture 18 ménagée entre les ouvertures de passage 14, 15, 16 et la première extrémité 13 du corps 12, à l'intérieur de laquelle fait saillie, selon l'axe du corps A et dans la direction de la première extrémité 13, un doigt 19 forgé avec le corps 12.The body further comprises an opening 18 formed between the passage openings 14, 15, 16 and the first end 13 of the body 12, within which it projects, along the axis of the body A and in the direction of the first end 13, a finger 19 forged with the body 12.
La longueur du doigt 19 est inférieur à la longueur de l'ouverture 18 suivant l'axe du corps A. L'espace délimité entre l'extrémité libre du doigt 19 et le corps 12 est au moins égal au diamètre courant d'un cordage.The length of the finger 19 is less than the length of the opening 18 along the axis of the body A. The space defined between the free end of the finger 19 and the body 12 is at least equal to the current diameter of a rope. .
Il est à noter que le nombre d'ouvertures de passage peut varier en fonction des applications, ce dispositif de freinage étant adapté pour des voiliers équipés de voiles ayant une superficie pouvant aller jusqu'à 40m2.It should be noted that the number of passage openings may vary according to the applications, this braking device being suitable for sailboats equipped with sails having an area of up to 40m 2 .
Nous allons à présent décrire les étapes successives d'un premier type de montage du dispositif de freinage sur le cordage principal. Selon une première étape représentée à la figure 3, une boucle 20 est formée sur le cordage principal 6. Une seconde étape représentée à la figure 4 consiste à passer la boucle 20 dans une ouverture de passage. Il s'agit, dans ce type de montage, de la première ouverture de passage 14. Dans une troisième étape représentée à la figure 5, la boucle 20 issue de l'ouverture de passage 14 est disposée autour du doigt 19, à l'intérieur de la seconde ouverture 18 située au niveau de la première extrémité 13 du corps 12.We will now describe the successive steps of a first type of mounting of the braking device on the main rope. In a first step shown in Figure 3, a loop 20 is formed on the main rope 6. A second step shown in Figure 4 is to pass the loop 20 in a passage opening. In this type of assembly, it is a question of the first passage opening 14. In a third step represented in FIG. 5, the loop 20 issuing from the passage opening 14 is arranged around the finger 19, at the inside the second opening 18 located at the first end 13 of the body 12.
Le dispositif de freinage 4 peut ainsi être positionné sur le cordage principal 6 sans besoin de détacher le dispositif de freinage 4 ou les extrémités du cordage 6.The braking device 4 can thus be positioned on the main rope 6 without the need to detach the braking device 4 or the ends of the rope 6.
La figure 6 décrit un deuxième type de montage dans lequel la boucle 20 est passée dans la deuxième ouverture de passage 15, puis dans la première 14, puis enfin autour du doigt 19. La figure 7 décrit un troisième type de montage dans lequel la boucle 20 est passée successivement dans la troisième ouverture de passage 16, dans la deuxième 15, dans la première 14 puis enfin autour du doigt 19.FIG. 6 describes a second type of assembly in which the loop 20 is passed through the second passage opening 15, then into the first 14, then finally around the finger 19. FIG. 7 describes a third type of assembly in which the loop 20 is passed successively in the third passage opening 16, in the second 15, in the first 14 and finally around the finger 19.
La figure 8 décrit un quatrième type de montage, similaire à celui représenté en figure 4, dans lequel la boucle 20 est passée successivement dans la troisième ouverture de passage 16, dans la deuxième 15, dans la première 14, dans l'ouverture 18 équipée du doigt, à nouveau dans la première ouverture de passage 14 puis enfin autour du doigt 19.FIG. 8 describes a fourth type of assembly, similar to that represented in FIG. 4, in which the loop 20 passes successively in the third passage opening 16, in the second 15, in the first 14, in the equipped opening 18. finger, again in the first opening passage 14 and finally around the finger 19.
Il est bien entendu possible d'utiliser toute autre variante de montage dérivant de manière évidente de celles exposées ci-dessus. Comme il va de soi, l'invention ne se limite pas à la forme de réalisation de ce dispositif de freinage, décrite ci-dessus à titre d'exemple, mais elle embrasse au contraire toutes les variantes. It is of course possible to use any other mounting variant obviously deriving from those described above. As goes without saying, the invention is not limited to the embodiment of this braking device, described above as an example, but it embraces all variants.
