Abstract
Description
Bôme à profil variable
L'invention concerne une bôme à profil variable.Boom with variable profile
The invention relates to a boom with variable profile.
Les bômes classiques ont un profil droit qui ne peut étre modifier, ce qui nécessite, lorsque le le vent change de direction, par rapport à la marche du voilier, le remplacement de la voile plate par une voile creuse (ou inversement), ce qui entraîne un effort physique souvent important pour l'équipage. The classic booms have a straight profile which cannot be modified, which requires, when the wind changes direction, compared to the sailboat's progress, the replacement of the flat sail with a hollow sail (or vice versa), which often involves significant physical effort for the crew.
En théorie, plus le bateau s'éloigne du lit du vent, plus la voile doit étre creuse; il est évidemment impossible d'emporter suffisamment de voiles différentes pour pcuvoir en changer à chaque modification de cap.In theory, the further the boat moves away from the wind bed, the more the sail should be hollow; it is obviously impossible to carry enough different sails to change it with each change of course.
La bôme, objet de cette invention, permet de remédier à cet inconvénient puisque, à partir d'une voile plate, il est possible d'obtenir une voile ayant le creux souhaitable. La description qui va suivre,aidée da dessin ci-annexé, permettra de bien comprendre l'invention.The boom, object of this invention, overcomes this drawback since, from a flat sail, it is possible to obtain a sail having the desirable hollow. The description which follows, aided by the appended drawing, will make it possible to understand the invention well.
Cette bôme se compose d'une poutre formée par deux tubes 1 & maintenus à une distance convenable à l'aide de goussets 3 placés et fixés de chaque côté des tubes 1 & , cette poutre servant de support à un ensemble d'éléments 4,5,6,7 articulés entre eux et composés, eux-mêmes,de deux profilés 8 placés de chaque c8té d'un méplat 9.This boom consists of a beam formed by two tubes 1 & kept at a suitable distance using gussets 3 placed and fixed on each side of the tubes 1 &, this beam serving as support for a set of elements 4, 5,6,7 articulated between them and composed, themselves, of two sections 8 placed on each side of a flat 9.
Les éléments 4,5,6,7 sont destinés à recevoir la bordure de la voile.The elements 4,5,6,7 are intended to receive the edge of the sail.
Les éléments 5 & sont reliés à des bielles lO & 1 dont la position est commandée par le déplacement d'une sorte de charriot composé de deux flasques 12 & 3, d'une entretoise 14 et d'une pièce filetée 15, cette pièce filerée i) traverse un écrou 16 faisant corps avec l'un des flasques. A chacune des extrémités de la tige fileté 15 est disposé un bouton moleté 17 qui permet d'agir sur celle-ci et, de ce fait, suivant le besoin, de bloquer, ou de libérer, le charriot commandant la position des bielles 10 & 1.Il est aise de comprendre que la position de ces bielles 10 & 1 mcdifie la position des éléments 4,5,6,7 créant ainsi une courbe, un creux, plus ou moins important, permettant d'obtenir une voile idéale puisque creuse sur l'avant et plate sur l'arrière, du point d'écoute au point de drisse.The elements 5 & are connected to connecting rods 10 & 1, the position of which is controlled by the displacement of a sort of carriage composed of two flanges 12 & 3, of a spacer 14 and of a threaded piece 15, this threaded piece i) passes through a nut 16 integral with one of the flanges. At each end of the threaded rod 15 is disposed a knurled button 17 which makes it possible to act on it and, therefore, according to the need, to block, or to release, the carriage controlling the position of the connecting rods 10 & 1.It is easy to understand that the position of these rods 10 & 1 mcdify the position of the elements 4,5,6,7 thus creating a curve, a hollow, more or less important, allowing to obtain an ideal sail since hollow on the front and flat on the back, from the listening point to the halyard point.
L'élément 4 en son extrémité opposée à l'élément 5, est articulé sur un point fixe 18 à l'aide d'un axe 19 ; l'élément 7 est articulé sur un point mobile 20, à l'aide d'un axe 21.The element 4 at its end opposite to the element 5, is articulated on a fixed point 18 using a pin 19; the element 7 is articulated on a mobile point 20, using an axis 21.
Cette b8e est reliée au mât à l'aide d'une articulation lui permettant tous les déplacements désirables, y compris de faire une révolution de 1000 autour de son axe.This b8e is connected to the mast using an articulation allowing it all the desirable displacements, including making a revolution of 1000 around its axis.
La présente invention ne se limite pas à ce qui a été plus spécialement décrit dans ce qui précède, et montré au dessin ci-annexé, elle en comprend toutes les variantes, tant dans ses dimensions que dans sa compesition et sa présentation. The present invention is not limited to what has been more particularly described in the foregoing, and shown in the attached drawing, it includes all variants thereof, both in its dimensions and in its composition and presentation.
