The diameter of the internal chamber 9 is O 1 in the region of the head 6 of the extrusion pellet and O 2 in the region of the end part 8 of the stalk 7 O1 = O 2; the diameter O of the internal chamber 9 is larger than the diameter O1 or O 2 by several tenths of a millimetre.

Description

L'invention a pour objet un rivet à chambrage interne permettant de riveter plusieurs épaisseurs avec un seul type de rivet. The subject of the invention is an internally chambered rivet making it possible to rivet several thicknesses with a single type of rivet.

Actuellement, il existe un grand nombre de rivets. Ces rivets sont en général classés en plusieurs catégories spécifiques de certaines épaisseurs. Toutes ces catégories de rivets augmentent le prix de revient, le volume de stockage etc. Currently, there are a large number of rivets. These rivets are generally classified into several specific categories of certain thicknesses. All these categories of rivets increase the cost price, the storage volume, etc.

L'invention tend à résoudre tous ces inconvénients. The invention tends to solve all these drawbacks.

Le rivet selon l'invention permet de riveter plusieurs épaisseurs avec un seul type de rivet, donc de diminuer le nombre de catégories de rivets. The rivet according to the invention makes it possible to rivet several thicknesses with a single type of rivet, therefore to reduce the number of categories of rivets.

A cet effet, le rivet selon l'invention comporte un chambrage interne, coaxial au corps du clou, formé au niveau du fût de la pastille d'extrusion et resserré à ses deux extrémités, par un épaulement, d'une part au niveau de la partie terminale du rut et d'autre part au niveau de la tête de la pastille d'extrusion. Le point de rupture du clou est situé au niveau de la chambre interne, peu avant l'épaulement qui est du cté de la pastille d'extrusion. La matière du fût d'extrusion est bloqué à deux extrémités durant l'extrusion du clou, la partie centrale du fût s'évase donc entre la tête du clou et la paroi, coté tête, à assembler. To this end, the rivet according to the invention comprises an internal recess, coaxial with the body of the nail, formed at the level of the barrel of the extrusion pad and tightened at its two ends, by a shoulder, on the one hand at the level of the end part of the rut and on the other hand at the level of the head of the extrusion pellet. The breaking point of the nail is located at the level of the internal chamber, shortly before the shoulder which is on the side of the extrusion pellet. The material of the extrusion barrel is blocked at two ends during the extrusion of the nail, the central part of the barrel therefore flares between the head of the nail and the wall, head side, to be assembled.

Les dessins ci-joints donnés à titre d'exemple indicatif et non limitatif permettront de comprendre aisément l'invention. Ils représentent un mode de réalisation préféré selon l'invention. The attached drawings given by way of indicative and non-limiting example will allow the invention to be easily understood. They represent a preferred embodiment according to the invention.

La figure 1 est une vue en coupe du rivet selon l'invention. Figure 1 is a sectional view of the rivet according to the invention.

La figure 2 est une vue en coupe du rivet, mis en place dans une pastille d'extrusion, au début de la traction sur le clou. Figure 2 is a sectional view of the rivet, placed in an extrusion pad, at the start of traction on the nail.

La figure 3 est une vue en coupe du rivet selon la figure 2 après la rupture du corps du clou et de la tête. Figure 3 is a sectional view of the rivet according to Figure 2 after the breakage of the body of the nail and the head.

Le rivet est composé d'un clou 1 formé par un corps 2, une tête 3 et un point de rupture 4 entre le corps 2 et la tête 3. Le clou est mis en place dans une pastille d'extrusion 5 composée d'une tête d'extrusion 6, d'un fût 7 et d'une partie terminale 8. The rivet is composed of a nail 1 formed by a body 2, a head 3 and a breaking point 4 between the body 2 and the head 3. The nail is placed in an extrusion pad 5 composed of a extrusion head 6, of a barrel 7 and of a terminal part 8.

Le rivet comporte un chambrage interne 9 formé au niveau du fût 7. The rivet has an internal recess 9 formed at the level of the barrel 7.

Cette chambre interne 9 a un diamètre de +, elle est resserrée à ses deux extrémités par un épaulement 10,11, qui se situe, d'une part au niveau de la partie terminale 8 du fût 7 et d'autre part au niveau de la tête 6 de de la pastille d'extrusion 5. Le diamètre de la chambre interne 9 est de + 1 au niveau de la tête 6 de la pastille d'extrusion 5 et de +2 au niveau de la partie terminale 8 du fût 7 b 1 = 2. Le diamètre + de la chambre interne 9 est plus grand de quelques dixièmes de millimètre que le diamètre + 1 ou + 2, par exemple
b 2 = 4 - 4/10.This internal chamber 9 has a diameter of +, it is tightened at its two ends by a shoulder 10.11, which is located, on the one hand at the level of the terminal part 8 of the barrel 7 and on the other hand at the level of the head 6 of the extrusion pellet 5. The diameter of the internal chamber 9 is + 1 at the head 6 of the extrusion pellet 5 and +2 at the terminal part 8 of the barrel 7 b 1 = 2. The diameter + of the internal chamber 9 is larger by a few tenths of a millimeter than the diameter + 1 or + 2, for example
b 2 = 4 - 4/10.

L'épaulement 11, du côté de la tête 3 du clou 1 ou partie terminale 8, est en forme de tronc de cône inversé tandis que l'épaulement 10, du côté de la tête 6 de la pastille d'extrusion 5, est perpendiculaire à l'axe du clou. The shoulder 11, on the side of the head 3 of the nail 1 or end portion 8, is in the form of an inverted truncated cone while the shoulder 10, on the side of the head 6 of the extrusion pad 5, is perpendicular to the axis of the nail.

Lorsque l'on tire sur le corps 2 du clou 1, le fût 7 de la pastille d'extrusion 5 gonfle dans son chambrage interne 9 qui est resserré à ses deux extrémités par des épaulements 10, 11 et la matière s'enroule et déborde autour et au-dessus de la tête 3 du clou 1. Ce chambrage interne 9 assure ainsi une étanchéité parfaite pour l'assemblage réalisé par ce type de rivet ; de plus, la quantité de matière disponible permet de riveter plusieurs épaisseurs avec un seul et même type de rivet ; enfin la résistance au cisaillement est largement augmentée compte tenu d'une extrusion à des diamètres différents +, +1 et +2 au niveau de la tête 3 du clou 1, du corps 2 du clou 1 et de la tête 6 de la pastille d'extrusion 5.  When the body 2 of the nail 1 is pulled, the barrel 7 of the extrusion pad 5 swells in its internal recess 9 which is tightened at its two ends by shoulders 10, 11 and the material rolls up and overflows around and above the head 3 of the nail 1. This internal recess 9 thus provides a perfect seal for the assembly produced by this type of rivet; moreover, the quantity of material available makes it possible to rivet several thicknesses with a single type of rivet; finally the shear strength is greatly increased taking into account an extrusion at different diameters +, +1 and +2 at the level of the head 3 of the nail 1, of the body 2 of the nail 1 and of the head 6 of the pellet d extrusion 5.
