Abstract

A device which allows the end-to-end assembly of two boat mast sections, characterised by the fact that the sleeve, by expansion, very slightly deforms the sections to be assembled so as to bring their four faces into contact with the sleeve.

Description

La prësente invention concerne un perfectionnement aux dispositifs permettant d'assembler bout a bout deux morceaux de profil de mât de bateau à voile. The present invention relates to an improvement to the devices making it possible to assemble end to end two pieces of sailboat mast profile.

Un mât de bateau à voile est constitué d'un profil d'aluminium sur lequel est fixé un certain nombre de pièces nécessaire au bon fonctionnement de la voile. I1 est. maintenu en position verticale sur un bateau par un systèrne de cables et de drisses. A sailing boat mast is made of an aluminum profile on which is fixed a number of parts necessary for the proper functioning of the sail. He is. kept upright on a boat by a system of cables and halyards.

Ce profil subit un certain nombre de contraintes et doit résister à des conditions de vent et de mer quelquefois très importantes. This profile is subject to a number of constraints and must withstand sometimes very strong wind and sea conditions.

Compte tenu de l'évolution du marché qui tend a produire des bateaux, de plus en plus grands, il devient difficile de produire des mats en un seul morceau. Given the evolution of the market which tends to produce increasingly large boats, it becomes difficult to produce masts in one piece.

Ceux-ci sont difficiles à manutentionner, a transporter.Ils peuvent quelquefois nécessiter des transports spéciaux. These are difficult to handle and transport, and may sometimes require special transport.

Une des solutions poÜl pallier a ces inconvénients est de les construire en deux morceaux et de relier ces deux morceaux par un manchon intérieur. One of the solutions for overcoming these drawbacks is to construct them in two pieces and to connect these two pieces by an inner sleeve.

Pour assembler entre eux bout a bout deux profils de mât de bateau, la méthode la plus courante consiste a reconstituer avec le profil existant par découpe et soudure un profil plus petit que l'on introduit a l'intérieur des deux profils à assembler. To assemble two end to end profiles of a boat mast, the most common method consists in reconstituting with the existing profile by cutting and welding a smaller profile which is introduced inside the two profiles to be assembled.

On les rend solidaires les uns des autres par des rivets aveugles ou de vis figure nO 1. They are made integral with each other by blind rivets or screws figure nO 1.

Les difficultés d'un tel assemblage sont nombreuses, car pour être effi cace le manchon doit adhérer parfaitement aux deux pièces à assembler. The difficulties of such an assembly are numerous, because to be effective the sleeve must adhere perfectly to the two parts to be assembled.

L'ajustage doit être parfait afin que les caractéristiques mécaniques de l'assemblage soient identiques a celles du profil en un seul morceau. The adjustment must be perfect so that the mechanical characteristics of the assembly are identical to those of the profile in one piece.

Les moments d'inertie en flexion ne doivent pas varier. Pour arriver a un tel résultat, il est sovent nécessaire de rentrer le manchon en force du fait qu'il est impossible 'obtenir du producteur des profils parfaitement identiques. The moments of inertia in bending must not vary. To achieve such a result, it is often necessary to force the sleeve in because it is impossible to obtain from the producer perfectly identical profiles.

En effet, dans un profil fermé, seul le pourtour(périmetre) reste constant. Les autres cotes par le jeu des tolérences varient de façon importante. Indeed, in a closed profile, only the periphery (perimeter) remains constant. The other ratings by the game of tolerances vary significantly.

En regle générale, si la cote de la plus grande largeur diminue , celle de la plus grande longueur augmente et inversement figure nO 2.As a general rule, if the dimension of the greatest width decreases, that of the greatest length increases and conversely figure nO 2.

Toutes ces raisons font qu'il est difficile et très onéreux a raccorder bout a bout les deux morceaux d'un même mât de bateau. All these reasons make it difficult and very expensive to connect end to end the two pieces of the same boat mast.

Le systeme d'assemblage bout a bout de deux morceaux de profil de mât de de bateau a voile selon notre invention permet de pallier a ces inconvénients. The end-to-end assembly system of two pieces of sailboat mast profile according to our invention overcomes these drawbacks.

L'invention consiste 1) A placer à l'intérieur des deux profils à assembler un ensemble de profil spécialement étudier qui assemblés entre eux et sous l'action de vis ou tout autre moyen de pression se déplacent et viennent s'appliquer parfaitement aux parois intérieur des deux profils à assembler. The invention consists 1) To place inside the two profiles to assemble a set of specially studied profile which assembled together and under the action of screws or any other pressure means move and come to apply perfectly to the walls inside of the two profiles to be assembled.

Apres immobilisation des moyens de pression, l'ensemble est en place prêt a fonctionner 2) A effectuer cette opération dans un laps de temps très court sans avoir. a utiliser pour ce faire d'une main d'oeuvre hautement spécialisée.After immobilizing the pressure means, the assembly is in place ready to operate 2) To perform this operation in a very short period of time without having. to be used for this purpose by a highly specialized workforce.

3) D'être assuré d'obtenir des resultats fiables et reproductibles.3) To be assured of obtaining reliable and reproducible results.

Exemple nO 1 Figure nO 3
Dans cet exemple nous avons conçu deux profils (4) et (5) qui coulissent entre eux le long des parois (1) et (2).Example nO 1 Figure nO 3
In this example we have designed two profiles (4) and (5) which slide between them along the walls (1) and (2).

Le manchon ainsi constitué une fois introduit dans les profils à assembler, on actionne les vis de pression. Lorsque l'on agit sur la vis (3) les profils (4) et (5) du manchon s'écartent et poussent sur les parois du mat en (6) et (7). The sleeve thus formed once introduced into the profiles to be assembled, the pressure screws are actuated. When one acts on the screw (3) the profiles (4) and (5) of the sleeve move apart and push on the walls of the mat in (6) and (7).

Par déformation, les faces intérieur (8) et (9) du profil de mât viennent s'appliquer parfaitement au manchon. Les quatre faces du profil de mât sont alors parfaitement ajustées au manchon qui remplit pleinement sa fonction. By deformation, the inner faces (8) and (9) of the mast profile are applied perfectly to the sleeve. The four sides of the mast profile are then perfectly adjusted to the sleeve which fully fulfills its function.

Exemple nO 2 Figure nO 4
Nous avons conçu ici trois profils.Example nO 2 Figure nO 4
We have designed three profiles here.

Les deux profils (10) et (11) sont reliés entre eux par les méplats type queue d'aronde (12) par serrage des méplats latéraux (12) a l'aide de vis de de serrage les profils (10) et (11) viennent appliquer une pression sur les parois (13) et (14) du profil à assembler.The two profiles (10) and (11) are interconnected by the dovetail type flats (12) by tightening the lateral flats (12) using clamping screws the profiles (10) and (11 ) apply pressure to the walls (13) and (14) of the profile to be assembled.

Les quatre faces du profil sont ainsi parfaitement en contact du manchon. The four faces of the profile are thus perfectly in contact with the sleeve.

Exemple nO 3 Figure nO 5
Comme ci-dessus, nous avons conçu trois profils.Example # 3 Figure # 5
As above, we have designed three profiles.

Les deux profils (15) et (16) sont reliés entre eux par les profils (17) et (18) qui viennent s'encliqueter les uns dans les autres.The two profiles (15) and (16) are interconnected by the profiles (17) and (18) which snap into each other.

Par action des vis les points (19) et (20) des profils (17) et (18) se rapprochent de la paroi du profil de mat et poussent les profils (15) et (16) qui viennent également en contact du mât à assembler.By the action of the screws the points (19) and (20) of the profiles (17) and (18) approach the wall of the mast profile and push the profiles (15) and (16) which also come into contact with the mast to to assemble.

Là aussi, les quatre faces du manchon sont en contact des profils a assembler. Again, the four faces of the sleeve are in contact with the profiles to be assembled.

Ces trois exemples ne sont pas restrictlfs. Tout système mettant en oeuvre des profils qui par action sur deux faces du profil a assembler permet aux deux autres par déformation de s'ajuster parfaitement est visé par l'invention.  These three examples are not restrictive. Any system using profiles which by action on two faces of the profile to be assembled allows the other two by deformation to adjust perfectly is covered by the invention.
