Description

La présente invention se rapporte aux mâts de bateau à voile. Elle concerne, plus particulièrement, une structure de mât à l'intérieur duquel peut prendre place la tringle d'un enrouleur de voile.The present invention relates to masts of a sailing boat. It relates, more particularly, to a mast structure inside which the rod of a sail furler can take place.

Il existe actuellement sur le marché un mât du type ci- dessus, qui est constitué par un profil étiré en métal ou alliage léger ayant une section en forme de fer à cheval défini par deux parois concentriques, l'une interne, l'autre externe, réunies par des entretoises.There is currently on the market a mast of the above type, which is constituted by a drawn profile of metal or light alloy having a horseshoe-shaped section defined by two concentric walls, one internal, the other external. , joined by spacers.

Une telle structure présente certains inconvénients. Tout d'abord, son profil à deux parois et entretoises rend sa fabrication assez difficile. De plus, sa rigidité n'est pas toujours suffisante, lorsque la voile est particulièrement sollicitée par le vent, pour empêcher l'ouverture du fer à cheval sous l'action de la tringle de l'enrouleur qui s'échappe ainsi de son logement. Enfin, l'existence de deux parois ne facilite pas la fixation d'une poulie au sommet du mât car il est nécessaire alors de procéder au perçage de ces deux parois.Such a structure has certain drawbacks. First of all, its profile with two walls and spacers makes its manufacture quite difficult. In addition, its rigidity is not always sufficient, when the sail is particularly stressed by the wind, to prevent the opening of the horseshoe under the action of the furling rod which thus escapes from its housing. . Finally, the existence of two walls does not facilitate the fixing of a pulley at the top of the mast because it is then necessary to drill these two walls.

La présente invention a pour but de fournir un mât de bateau qui ne souffre pas des inconvénients ci dessus.The object of the present invention is to provide a boat mast which does not suffer from the above drawbacks.

Pour atteindre ce but, le mât selon l'invention présente, en section transversale, une portion externe ayant grossièrement la forme d'un fer à cheval, une portion interne disposée à l'intérieur de la portion externe pour la renforcer et ayant la forme d'un arc de cercle, de même axe de symétrie que celle-ci et ouvert du même côté qu'elle, dont les extrémités sont respectivement reliées aux branches du fer à cheval et deux portions de fermeture fixées aux extrémités respectives desdites branches et formant deux lèvres qui obturent partiellement l'ouverture du fer à cheval en laissant subsister entre elles un espace suffisant pour permettre le passage d'une voile fixée à l'intérieur du mât.To achieve this object, the mast according to the invention has, in cross section, an external portion having roughly the shape of a horseshoe, an internal portion disposed inside the external portion to reinforce it and having the shape an arc of a circle, of the same axis of symmetry as the latter and open on the same side as it, the ends of which are respectively connected to the branches of the horseshoe and two closure portions fixed to the respective ends of said branches and forming two lips which partially obstruct the horseshoe opening, leaving sufficient space between them to allow the passage of a sail fixed inside the mast.

De façon avantageuse, le mât est constitué par l'assemblage de deux profilés formant respectivement les deux portions de fermeture et d'au moins un troisième profilé formant les portions externe et interne.Advantageously, the mast is constituted by the assembly of two sections respectively forming the two closure portions and at least one third section forming the outer and inner portions.

D'autres caractéristiques de l'invention, ainsi que ses avantages, ressortiront de la description qui va suivre, faite en regard de la figure annexée et donnant, à titre explicatif mais nullement limitatif, une forme de réalisation avantageuse d'un tel mât. Cette figure est une vue en coupe transversale d'un mât de bateau selon l'invention.Other characteristics of the invention, as well as its advantages, will emerge from the description which follows, given with reference to the appended figure and giving, by way of explanation but in no way limiting, an advantageous embodiment of such a mast. This figure is a cross-sectional view of a boat mast according to the invention.

Le mât représenté sur la figure possède une structure dont la section peut être décomposée en quatre portions, à savoir:

  • - une portion externe 10 ayant grossièrement la forme d'un fer à cheval, d'axe de symétrie xx', dont la partie traversée par cet axe constitue l'avant du mât;
  • - une portion interne de renforcement du fer à cheval 12 formée d'une partie sensiblement en arc de cercle 12a, également d'axe de symétrie x x' et ouvert du même côté que le fer à cheval et de deux bras de raccordement 12b reliant respectivement les deux extrémités de l'arc de cercle aux branches du fer à cheval; et
  • - deux portions de fermeture identiques 14, disposées respectivement au niveau de l'extrémité des branches du fer à cheval, c'est à dire à l'arrière du mât, et formant deux lèvres, dirigées en direction l'une de l'autre qui laissent subsister entre elles un léger espace.
The mast shown in the figure has a structure whose section can be broken down into four portions, namely:
  • - An outer portion 10 having roughly the shape of a horseshoe, of axis of symmetry xx ', the part crossed by this axis constitutes the front of the mast;
  • - an internal portion of reinforcement of the horseshoe 12 formed of a part substantially in an arc of a circle 12a, also of axis of symmetry xx 'and open on the same side as the horseshoe and of two connecting arms 12b connecting respectively the two ends of the arc of a circle at the branches of the horseshoe; and
  • - two identical closure portions 14, respectively disposed at the end of the horseshoe arms, that is to say at the rear of the mast, and forming two lips, directed in the direction of one another which leave a slight space between them.

Pour fixer les idées, et à titre purement indicatif, le rapport entre la dimension du fer à cheval 10 selon l'axe xx' (longueur) et sa plus grande dimension selon une direcper- pendiculaire à cet axe (largeur) est d'environ 1,5. Le rapport entre sa largeur et la dimension de son ouverture est d'environ 1,6. Pour ce qui concerne la portion 12, dont on peut dire, pour simplifier, qu'elle est en forme de Q, l'arc de cercle 12a couvre un angle de 1600 à 1700 environ et le rapport entre son rayon et la largeur du fer à cheval est d'environ 0,35 à 0,40. La distance qui sépare son centre de la base du fer à cheval représente entre 25% et 30% de sa longueur.To fix the ideas, and purely for information, the ratio between the size of the horseshoe 10 along the axis xx '(length) and its largest dimension in a direction perpendicular to this axis (width) is approximately 1.5. The ratio of its width to the size of its opening is approximately 1.6. As regards the portion 12, which can be said, for simplicity, that it is in the shape of a Q, the arc of a circle 12a covers an angle of approximately 160 0 to 170 0 and the ratio between its radius and the width horseshoe is about 0.35 to 0.40. The distance from its center to the base of the horseshoe is between 25% and 30% of its length.

Il apparait immédiatement que, grâce à la présence de la portion de renforcement en Q, une telle structure possède une excellente rigidité. Celle-ci peut encore être améliorée par deux entretoises 12c reliant le corps de l'arc de cercle aux branches du fer à cheval.It immediately appears that, thanks to the presence of the reinforcing portion in Q, such a structure has excellent rigidity. This can be further improved by two spacers 12c connecting the body of the arc to the branches of the horseshoe.

La structure ainsi constituée offre, dans sa moitié la plus proche de l'ouverture du fer à cheval, un volume libre qui sert à recevoir la tringle d'un enrouleur de voile. L'espace qui sépare les extrémités des deux lèvres 14 est destiné au passage de la voile.The structure thus formed offers, in its half closest to the opening of the horseshoe, a free volume which is used to receive the rod of a sail furler. The space which separates the ends of the two lips 14 is intended for the passage of the sail.

La forme générale de la structure étant décrite, il y a lieu maintenant de préciser la manière dont elle est réalisée.The general form of the structure having been described, it is now necessary to specify the manner in which it is produced.

Dans l'exemple représenté sur la figure 1, le mât est formé par l'assemblage de quatre profilés A,B,C et D réalisés par étirage en métal ou alliage léger, tel que l'aluminium.In the example shown in Figure 1, the mast is formed by the assembly of four sections A, B, C and D made by drawing in metal or light alloy, such as aluminum.

Plus précisément, la portion en fer à cheval 10 et la portion en Q 12 sont constituées par les deux profilés A et B dont l'un A forme l'arrondi du fer à cheval et une partie de ses branches, tandis que l'autre B forme le reste des branches et la totalité de la portion en Q. Ces deux profilés sont assemblés par un système à cran en exploitant la relative élasticité des branches du profilé A. Celui-ci comporte, à chaque extrémité, une partie saillante 16, dirigée vers t'intérieur, qui prend place dans un cran 18 ménagé du côté extérieur de l'extrémité correspondante du profilé B. Lors de l'assemblage, l'élasticité du profilé A lui permet de s'ouvrir légèrement pour laisser pénétrer, entre les extrémités de ses branches, les extrémités du profilé B jusqu'à ce que les parties saillantes 16 viennent s'emboîter dans les crans 18.More specifically, the horseshoe-shaped portion 10 and the Q-shaped portion 12 are formed by the two sections A and B, one of which A forms the roundness of the horseshoe and part of its branches, while the other B forms the rest of the branches and the entire portion in Q. These two sections are assembled by a notch system by exploiting the relative elasticity of the branches of section A. This comprises, at each end, a projecting part 16, facing inward, which takes place in a notch 18 formed on the outside of the corresponding end of the profile B. During assembly, the elasticity of the profile A allows it to open slightly to allow penetration, between the ends of its branches, the ends of the profile B until the projecting parts 16 fit into the notches 18.

Les deux autres profilés C et D sont identiques et constituent respectivement les deux portions de fermeture ou lèvres 14 de la structure. Ces profilés qui obturent partiellement la partie arrière du mât en ne laissant subsister qu'une fente pour le passage de la voile, sont accrochés aux extrémités du profilé B. Ils présentent une paroi arrondie 14a formant l'extrémité de la lèvre et se prolongeant par une paroi 14b regardant vers l'intérieur du mât et par une paroi 14c regardant vers l'extérieur. La paroi 14b a une longueur sensiblement double de celle de la paroi 14c qui se termine au niveau de l'extrémité du profilé B. Enfin, une paroi de renforcement 14d relie l'extrémité de la paroi 14c au milieu de la paroi 14b. L'arrondi de la paroi 14a permet d'offrir à la voile, lorsqu'elle vient en contact avec la lèvre, un profil adouci qui réduit sensiblement son risque d'être endommagée.The other two sections C and D are identical and respectively constitute the two closure portions or lips 14 of the structure. These sections which partially close the rear part of the mast, leaving only a slot for the passage of the sail, are attached to the ends of the section B. They have a rounded wall 14a forming the end of the lip and extending by a wall 14b looking towards the inside of the mast and a wall 14c looking towards the outside. The wall 14b has a length substantially double that of the wall 14c which ends at the end of the profile B. Finally, a reinforcing wall 14d connects the end of the wall 14c in the middle of the wall 14b. The rounded wall 14a makes it possible to offer the sail, when it comes into contact with the lip, a softened profile which significantly reduces its risk of being damaged.

L'accrochage des profilés C et D aux extrémités du profilé B est réalisé en deux points. Plus précisément, la paroi 14b se termine par un arrondi 20 qui prend place dans une rainure 22 ménagée sur l'intérieur du profilé B. Un méplat 24 est prévu à la base de l'arrondi 20 pour permettre l'introduction de celui-ci dans la rainure 22. L'autre point d'accrochage se situe à l'extrémité du profilé B qui comporte une partie saillante crantée 26 coopérant avec une autre partie saillante crantée 28, de forme complémentaire, qui prolonge la paroi 14d. Les profilés C et D sont ainsi accrochés au pofilé B par un système à emboitement et par un système à cran.The attachment of profiles C and D to the ends of profile B is carried out at two points. More specifically, the wall 14b ends in a rounded 20 which takes place in a groove 22 formed on the inside of the profile B. A flat 24 is provided at the base of the rounded 20 to allow the introduction thereof. in groove 22. Water the attachment point is located at the end of the profile B which has a notched protruding part 26 cooperating with another notched protruding part 28, of complementary shape, which extends the wall 14d. Profiles C and D are thus hooked to profile B by a snap-in system and by a notch system.

La paroi 14c comporte avantageusement une ouverture débouchant dans une cavité 30 qui permet la fixation d'une voile auxiliaire.The wall 14c advantageously comprises an opening opening into a cavity 30 which allows the attachment of an auxiliary sail.

Afin de garantir le maintien en place des profilés C et D, qui peuvent être soumis de la part de la voile à de fortes sollicitations en direction de l'intérieur du mât, il est avantageux de renforcer leur accrochage à l'aide de rivets 32 fixés dans les parties crantées 26 et 28. Ceci pose cependant un problème. Etant donné, en effet, que l'espace laissé libre entre les extrémités des lèvres est faible, il n'est pas possible lorsque les profilés C et D sont rivetés, d'accéder à l'enrouleur de voile qui se trouve pratiquement emprisonné dans le mât. Pour résoudre ce problème, les profilés C et D sont réalisés, sur la longueur du mât, en plusieurs tronçons. Les uns sont rivetés, tandis que les autres, au niveau des zones où l'accès de l'enrouleur doit être possible, ne le sont pas et peuvent ainsi être enlevés aisémentIn order to guarantee that the profiles C and D are held in place, which can be subjected to heavy loads on the part of the sail towards the interior of the mast, it is advantageous to strengthen their attachment by means of rivets 32 fixed in the notched parts 26 and 28. This however poses a problem. Given, in fact, that the space left free between the ends of the lips is small, it is not possible when the sections C and D are riveted, to access the sail furler which is practically trapped in the mast. To solve this problem, sections C and D are made, along the length of the mast, in several sections. Some are riveted, while others, in the areas where access to the reel must be possible, are not and can therefore be easily removed

La structure décrite reste sensiblement la même pour toutes les dimensions de mâts. Par contre, la manière dont cette structure est réalisée, et plus particulièrement le nombre de profilés utilisés, peuvent différer. L'exemple décrit, utilisant deux profilés pour constituer la portion en fer à cheval et la portion en θ, concerne une structure dont la section a une longueur de 44 cm et une largeur de 30 cm. Pour un mât de plus grandes dimensions, il peut être avantageux de réaliser le profilé A en deux, voire trois parties. A l'inverse, pour un petit mât, les profilés A et B peuvent être remplacés par un profilé unique. Il faut aussi mentionner que ces deux profilés peuvent être assemblés par soudage, collage ou rivetage.The structure described remains essentially the same for all dimensions of masts. On the other hand, the way in which this structure is produced, and more particularly the number of profiles used, may differ. The example described, using two sections to constitute the horseshoe portion and the θ portion, relates to a structure whose section has a length of 44 cm and a width of 30 cm. For a mast of larger dimensions, it may be advantageous to produce the section A in two, or even three parts. Conversely, for a small mast, profiles A and B can be replaced by a single profile. It should also be mentioned that these two profiles can be assembled by welding, gluing or riveting.

Les avantages de l'invention apparaissent maintenant plus clairement. Tout d'abord, la structure adoptée et, plus précisément, le fer à cheval à paroi unique, renforcé par un profil en Ω, donne au mât une excellente rigidité qui est, par ailleurs, sensiblement renforcée par les deux lèvres arrières. Grâce à cette rigidité et à la présence des lèvres qui referment la cavité contenant la tringle de l'enrouleur, celle-ci non seulement ne risque pas de sortir du mât, mais aussi reste droite, ce qui est important pour que l'enroulement de la voile se fasse dans de bonnes conditions. Cette rigidité n'empêche pas cependant, grâce au mode d'accrochage des lèvres et leur réalisation en plusieurs tronçons, un accès très facile aux organes importants de l'enrouleur de voile emprisonné à l'intérieur du mât. De plus, les profilés utilisés ont des formes qui rendent leur fabrication très facile. Enfin, la fixation des poulies à t'avant du mât ne pose pas de problème car une paroi seulement doit être percée.The advantages of the invention now appear more clearly. First of all, the structure adopted and, more precisely, the single-walled horseshoe, reinforced by an Ω profile, gives the mast an excellent rigidity which is, moreover, appreciably reinforced by the two rear lips. Thanks to this rigidity and the presence of the lips which close the cavity containing the reel rod, the latter not only does not risk coming out of the mast, but also remains straight, which is important for the winding of sailing is done in good conditions. This rigidity does not, however, prevent, thanks to the method of attachment of the lips and their realization in several sections, very easy access to the important organs of the sail furler trapped inside the mast. In addition, the profiles used have shapes that make their manufacture very easy. Finally, the fixing of the pulleys to the front of the mast poses no problem since only one wall must be pierced.
